Lateral roots, including adventitious roots, are the main component of rapeseed roots with support, absorb, and synthesis functions and their morphological parameters directly affecting the plant's aboveground growth and yield. Root biomass, as a material base for lateral root growth, can be used as a link between plant phenotypes and their physiological processes, as well as to enhance root 3D growth model mechanisms and accuracy. To quantify the relationships between lateral root morphological indices and the corresponding organ biomass for rapeseed, we used two cultivars, NY 22 (conventional) and NZ 1818 (hybrid), and conducted cultivar and fertilizing cylindrical tube experiments during the 2016–2019, with two fertilizer levels, no fertilizer, and 180 kg N ha−1 fertilizer. The lateral root biomass and morphological parameters were determined during the whole growth period. The biomass‐based lateral root morphological parameter models were developed by analyzing the quantitative relationship between the lateral root morphological indices and their corresponding biomass, and the descriptive models were verified with independent experimental data. The results showed that the correlation (r) of simulated and observed values for the lateral root morphological parameters are all greater than 0.9 with significant levels at p < 0.001. The absolute values of the average absolute difference (da) of simulated and observed values for the lateral root length (LLR), lateral root average diameter (ADLR), lateral root surface area (SALR), and lateral root volume (VLR) are −30.408 cm, −0.003 mm, 12.902 cm2, and 0.039 cm3, respectively. The RMSE values are 175.183 cm, 0.010 mm, 59.710 cm2, and 1.513 cm3, respectively. The ratio of da to the average observed values (dap) for the LLR and VLR are all less than 5%, and the ADLR and SALR are all <6%. The models developed in this paper have good performance and reliability for predicting lateral root morphological parameters of rapeseed. The study provides a mechanistic method for linking the rapeseed growth model with the morphological model using corresponding organic biomass and laying a good foundation for establishing a 3D morphological model for rapeseed root system based on biomass.

The critical platform studies literature is increasingly considering the role of social difference as a structuring logic in the platform economy, complementing understandings of worker precarity facilitated by worker misclassification and algorithmic management. Contributing to this literature, this paper demonstrates how platforms and police produce carceral geographies that manage and exploit immigrant delivery workers as surplus populations. The carceral geographies of the platform economy account for both how carceral space produces and manages the surplus populations from which platform capital draws its workers, facilitating the disposability and exploitation of workers. Focusing on South Asian delivery workers in New York City, the paper uses the example of bike registrations to show how police and platforms expand carceral spaces in immigrant communities, increasing their vulnerability to premature death and violence. Finally, it suggests how delivery worker organising offers instances of situated resistance that challenge platform capital and carceral logics. [ABSTRACT FROM AUTHOR]

More than 30 years after its premiere, Seinfeld continues its run as a seminally popular television show. On October 1, 2021, five‐year streaming rights to the show were purchased by Netflix for $500 million. Set in New York City, where rent control laws have a long history, several episodes of the show consider the trials of apartment living, including shortages, tastes for discrimination by sellers, bribery, search costs, and quality degradation. Seinfeld also illustrates the informal process through which rent‐controlled apartments are advertised (e.g., less advertising under rent control shortage). This paper argues that popular media can be used as an effective pedagogical tool in learning. This paper analyzes four episodes of Seinfeld to help students identify and differentiate the very real costs of rent control. The paper also guides students to appreciate the difficulty in crafting a policy that is free of unintended consequences. [ABSTRACT FROM AUTHOR]

BOND prices ,PAPER money ,WAR ,ACCOUNTS payable - Abstract
The article reports on conversion clause in the United States. American monetary history is full of strange happenings and queer events beginning with the resolution of Massachusetts Bay Colony in 1690 explaining the issue of the first paper money. It referred to "the sundry considerable debts" which had been contracted "for maintaining their Majesties" interests against hostile invasions of their French and Indian enemies," the actual fact being that the colony had sent an expedition against Quebec in the expectation that plunder would pay the costs thereof. It is true that the highest prices at which the five-twenty bonds sold on the New York market never exceeded 14 points above par in 1864 and 12 points above in 1865, whereas at the same time the premiums on gold were in the ranges 77-85 and 98-105, respectively. In the years following the war the gap between the premium on the bonds and on gold steadily narrowed. By late 1869 the gap had disappeared and from 1870 on the advantage clearly lay with the bonds, their market premium over par persistently exceeding the gold premium. Senator John Sherman pointed out on the floor of the Senate, March 6, 1876, that even the government's 5 per cent bonds had been "at par with gold for the past five years" while the greenbacks had been "from 6 to 22 per cent below gold."

In 2018, the New York City (NYC) Department of Health and Mental Hygiene piloted a novel jurisdictional risk assessment (JRA) for public health disasters using the analytic hierarchy process (2018 JRA‐AHP). This new approach offers a replicable and equitable model for consensus decision‐making that incorporates the complexities of disaster preparedness. Its main contribution to the field is to offer a practical manifestation of emergency management's Whole Community Approach. The 2018 JRA‐AHP applied this principle by expanding traditional definitions of 'expertise' to include lived experience of disaster and facilitating direct participation in the risk decision by a variety of individuals with diverse backgrounds, expertise and knowledge of public health disasters. This paper describes the theory, methods and results behind the JRA‐AHP. The paper also presents a critical analysis of public health disaster risk assessments; contextualizes the Whole Community Approach using models of the relationship between democratic governments and communities; and addresses the practical applications of the 2018 JRA‐AHP in NYC while exploring the potential challenges that other jurisdictions may face in attempted adaptation.

While matters of food waste and soil have become vital research arenas, compost remains the Cinderella of human geographical enquiry. In response, this paper brings compost to the centre of debates at the intersection of diverse economies and circular economy. In particular, the concept of community composting and the care involved in such practices is used to offset and problematise the technoscientific bias in circular economy discourses. Extending feminist perspectives on care in soil studies, this paper focuses on the careful circularities that are realised through community composting in New York City. This case study provides not only a material space for examining community composting but also a unique opportunity to consider the colliding worlds of worth that operate in and around urban sustainability transitions to zero waste. Drawing empirical insights from interviews, participant observation, and document analysis, this paper argues for a sensitisation of circular economy policy and research to matters of care and diverse economies as a means to better understand motivations, justifications, and outcomes of efforts to reorient food systems onto more sustainable pathways. We argue that privileging care in this way helps to shift focus away from dominant narratives of "scaling‐up" towards sustainability to a more relational perspective that sees transformation in connecting, deepening, and even scaling‐down. This means attending to the micro as well as macro transformations needed to enact the required sustainability transitions. [ABSTRACT FROM AUTHOR]

A controversial U.S. Supreme Court decision in Kelo v. City of New London (2005) which did not limit the use of state's eminent domain powers, led to an unprecedented legislative reaction by almost all 50 states. Of all, New York State stands out as one of the single states not to respond with a legislative amendment. In this study, I ask whether the state's predation was greater in the years following these legal and political developments, in light of the freedom which was granted to local politicians by both the Supreme Court and the state's legislators. The article hypothesizes that contrary to common perceptions, judicial decisions impact local government actions even when no limits on the use of powers are being posed. I use rigorous statistics and scrupulously defined data to expand scholarly understanding of the aftermath of the judicial decision in Kelo. The main finding is that the decision has in fact affected political behavior, but in the opposite direction than commonly expected: politicians in New York City acted consistently with public opinion, which was hostile too Kelo, not by changing the law, but by changing their practice. Studying all known taking exercises in New York City between 1991 and 2019, the paper finds no increase in the number of development projects involving condemnations after 2005. In fact, the probability of a taking for economic development or urban renewal dropped by 90%. The use of eminent domain for such projects declined even when both state and federal courts refrain from interposing any actual limit on its use. The paper lends qualified support to an alternative assertion that takings decisions by government officials are largely shaped by planning and political needs and that officials are sensitive to revealed public preferences even when there is no constitutional or legal impediment on their exercise of power.

This paper considers how and to what ends commoning practices can take shape in direct response to the spectres and/or realities of eroding resources (we focus especially on public resources) within iterations of what we term "salvage commoning". We show how, in such contexts, commoning practices may potentially alleviate but also potentially (re)produce inequities, exclusions, and resource retractions. To illustrate, we draw upon two examples: parent‐teacher organisations in Washington, DC, and block associations in New York City. In both instances, people have cooperatively built new relations, coordinated voluntary labour, and stewarded resources in connection with specific commons (public schools and urban spaces) threatened by disinvestment and crisis. We show how troubling alignments and exclusions can emerge under these conditions, suggesting critical questions about the starkly mixed potential of salvage commoning—especially in the face of ongoing and emerging crises in which such orientations are likely to become increasingly prevalent.

Puerto Rico is one of the world's oldest colonies, with thousands of its people dislocated to the United States (U.S.) mainland in the wake of Hurricane Maria and the ongoing economic crisis. However, since the 2019 protests ousting then governor Rosello, Puerto Ricans across the Diaspora are imagining new emancipatory realities, including the possibility of independence. This paper draws on data from the Colonial Mentality Study in New York City (CMS‐NYC, N = 19) to explore how Puerto Ricans in the Diaspora narrativize new political possibilities despite the challenges posed by post‐disaster migration and racial and economic inequality. Using a decolonial psychoanalytic approach, we show how two colonial logics—moving "up and out" of Puerto Rico and "up and in" American capitalism—are textured by discourses of racial inferiority and upward mobility, and illustrate how these are experienced by Puerto Ricans who identify as Multiracial (Multiracial‐Identified Puerto Rican, N = 11), and Puerto Ricans who identify as Black (BIPR, N = 8). Reading our findings in the sociogenic context of race, class, and colonialism in Puerto Rico, and race and class among Puerto Ricans in NYC, we explore how racism toward Puerto Ricans and racism among Puerto Ricans intersect with notions of upward mobility, revealing how anti‐Blackness supports economic inequality in the U.S. mainland alongside with Puerto Rico's colonial situation. Complementing decolonial psychoanalytic theory with the Afro‐Puerto Rican radical tradition, we outline the implications of this research for future scholarship, clinical practice, and political action.

This paper follows the 22‐year journey of a small community‐based program with roots in a psychoanalytic training institute, to the program's current status as an independent non‐profit organization serving families throughout the Bronx with psychodynamic, attachment‐based parent‐infant treatment. The product of an unusual collaboration among a psychoanalytic training institute, a program of the NYC Department of Education and several generous foundations, we aimed to offer teen mothers a dyadic model of parent‐infant intervention based on the principles of psychodynamic theory, attachment theory, and mentalization through the lens of an infant mental health perspective. Underlying the creation, implementation, and expansion of the Chances for Children organization at every level were questions of basic trust and mistrust, class, and culture. With this in mind, we describe the development of the model, collaborations with institutions and communities, and the obstacles we encountered along the way. On a macro level, we consider questions of class, culture, and institution that we encountered on every level in institutional bureaucracy, in community outreach, and in collaborating programs. On a more micro level, we use the contexts of a teen‐parent therapeutic group and a dyadic mother‐child treatment to address issues that arise when white, middle‐class clinicians of privilege work in communities of color that are frequently suffering insufficiencies in food, housing, jobs, and experiencing random violence. Finally, we reflect on what has made the work of Chances for Children possible, successful, and enduring even as we embarked on the telehealth practices necessary during the COVID pandemic.

New York City faces accelerating inundation risk from sea level rise, subsidence, and increasing storm intensity from natural and anthropogenic causes. Here we calculate a previously unquantified contribution to subsidence from the cumulative mass and downward pressure exerted by the built environment of the city. We enforce that load distribution in a multiphysics finite element model to calculate expected subsidence. Complex surface geology requires multiple rheological soil models to be applied; clay rich soils and artificial fill are calculated to have the highest post‐construction subsidence as compared with more elastic soils. Minimum and maximum calculated building subsidence ranges from 0 to 600 mm depending on soil/rock physical parameters and foundation modes. We compare modeled subsidence and surface geology to observed subsidence rates from satellite data (Interferometric Synthetic Aperture Radar and Global Positioning System). The comparison is complicated because the urban load has accumulated across a much longer period than measured subsidence rates, and there are multiple causes of subsidence. Geodetic measurements show a mean subsidence rate of 1–2 mm/year across the city that is consistent with regional post‐glacial deformation, though we find some areas of significantly greater subsidence rates. Some of this deformation is consistent with internal consolidation of artificial fill and other soft sediment that may be exacerbated by recent building loads, though there are many possible causes. New York is emblematic of growing coastal cities all over the world that are observed to be subsiding (Wu et al., 2022, https://doi.org/10.1029/2022GL098477), meaning there is a shared global challenge of mitigation against a growing inundation hazard. Plain Language Summary: As coastal cities grow globally, the combination of construction densification and sea level rise imply increasing inundation hazard. The point of the paper is to raise awareness that every additional high‐rise building constructed at coastal, river, or lakefront settings could contribute to future flood risk, and that mitigation strategies may need to be included. The subsidence mapping concept helps to quantify the hazard and adds specificity to soil types and conditions. We present satellite data that show that the city is sinking 1–2 mm/tr with some areas subsiding much faster. Key Points: More than 8 million people live in New York City, which is observed to be sinking 1–2 mm/year, while sea level risesWe calculate the mass of all buildings in New York City and model the subsidence caused by the pressure they exert on the EarthWe show detailed images of observed subsidence in New York City from satellite data [ABSTRACT FROM AUTHOR]

The Inner Shell Spectroscopy (ISS) beamline on the 8-ID station at the National Synchrotron Light Source II (NSLS-II), Upton, NY, USA, is a high-throughput X-ray absorption spectroscopy beamline designed for in situ, operando, and time-resolved material characterization using high monochromatic flux and scanning speed. This contribution discusses the technical specifications of the beamline in terms of optics, heat load management, monochromator motion control, and data acquisition and processing. Results of the beamline tests demonstrating the quality of the data obtainable on the instrument, possible energy scanning speeds, as well as long-term beamline stability are shown. The ability to directly control the monochromator trajectory to define the acquisition time for each spectral region is highlighted. Examples of studies performed on the beamline are presented. The paper is concluded with a brief outlook for future developments. [ABSTRACT FROM AUTHOR]

In Syracuse, New York more than 10% of children are lead poisoned each year, a toxic exposure that lowers the children's ability to learn and increases risky behaviors in adolescence. African American children are affected at nearly twice the rate of White children. We describe a community‐university collaboration to reduce childhood lead poisoning in Syracuse, and the effects these efforts have had on public policy to date. This paper documents the effectiveness of the Community Action, Research, and Education model to deliver community‐based prevention strategies on child lead poisoning in Syracuse, New York. The community‐based strategies were successful for promoting legal and policy change, increasing the public awareness of this tragic problem, holding elected and appointed officials to their commitments in addressing this toxic injustice, and obtaining needed intervention and disability accommodations for lead‐poisoned children in the community and educational institutions.

Pork‐barrel spending is a form of public spending controlled by individual legislators and primarily serving a local interest. In this paper, we investigate the impact of a type of pork, council member capital discretionary education spending voted upon in a participatory budgeting (PB) process, on school budgets and performance in New York City. Exploiting plausibly exogenous variation in discretionary spending induced by the PB elections, we find winning a PB election increases school pork appropriations. However, we find no evidence these transfers from council members improve fiscal and performance outcomes. Further, pork may interfere with school budgeting. Applications for practice: Even though NYC participatory budgeting elections are nonbinding, NYC council members fund capital projects that win these elections. As a result, winning schools experience large appropriation increases. We call this discretionary funding designated by one council member "pork" funding.Pork funding did not significantly affect fiscal outcomes (operating spending) or academic performance (test scores and attendance). We can rule out large changes for both, although medium‐sized improvements in school environment perception are possible.Estimates suggest participatory budgeting projects—and the pork they precipitate—may have small disruptive effects on school budgets by shifting resources from instruction and student support to building services. Qualitative data also suggest participatory budgeting projects may lack coordination with school budgets.Pork funding may increase total capital resources in recipient schools. However, the timing of capital expenditures limits power to identify the size of this effect or rule out the crowd‐out of other capital resources. [ABSTRACT FROM AUTHOR]

Noise is one of the primary quality‐of‐life issues in urban environments. In addition to annoyance, noise negatively impacts public health and educational performance. While low‐cost sensors can be deployed to monitor ambient noise levels at high temporal resolutions, the amount of data they produce and the complexity of these data pose significant analytical challenges. One way to address these challenges is through machine listening techniques, which are used to extract features in attempts to classify the source of noise and understand temporal patterns of a city's noise situation. However, the overwhelming number of noise sources in the urban environment and the scarcity of labeled data makes it nearly impossible to create classification models with large enough vocabularies that capture the true dynamism of urban soundscapes. In this paper, we first identify a set of requirements in the yet unexplored domain of urban soundscape exploration. To satisfy the requirements and tackle the identified challenges, we propose Urban Rhapsody, a framework that combines state‐of‐the‐art audio representation, machine learning and visual analytics to allow users to interactively create classification models, understand noise patterns of a city, and quickly retrieve and label audio excerpts in order to create a large high‐precision annotated database of urban sound recordings. We demonstrate the tool's utility through case studies performed by domain experts using data generated over the five‐year deployment of a one‐of‐a‐kind sensor network in New York City.

Timely diagnostic testing for active SARS‐CoV‐2 viral infections is key to controlling the spread of the virus and preventing severe disease. A central public health challenge is defining test allocation strategies with limited resources. In this paper, we provide a mathematical framework for defining an optimal strategy for allocating viral diagnostic tests. The framework accounts for imperfect test results, selective testing in certain high‐risk patient populations, practical constraints in terms of budget and/or total number of available tests, and the purpose of testing. Our method is not only useful for detecting infections, but can also be used for long‐time surveillance to detect new outbreaks. In our proposed approach, tests can be allocated across population strata defined by symptom severity and other patient characteristics, allowing the test allocation plan to prioritize higher risk patient populations. We illustrate our framework using historical data from the initial wave of the COVID‐19 outbreak in New York City. We extend our proposed method to address the challenge of allocating two different types of diagnostic tests with different costs and accuracy, for example, the RT‐PCR and the rapid antigen test (RAT), under budget constraints. We show how this latter framework can be useful to reopening of college campuses where university administrators are challenged with finite resources for community surveillance. We provide a R Shiny web application allowing users to explore test allocation strategies across a variety of pandemic scenarios. This work can serve as a useful tool for guiding public health decision‐making at a community level and adapting testing plans to different stages of an epidemic. The conceptual framework has broader relevance beyond the current COVID‐19 pandemic. [ABSTRACT FROM AUTHOR]

This paper's findings suggests that the New York City fiscal crisis by itself did not lead to a fundamental change in risk perceptions of investors, resulting in higher interest rates in the municipal bond market. The monthly prediction errors generated by time series tests were relatively small and none were statistically significant. Only the signs on the prediction errors for June, July, and August were consistent with a New York City effect. Thus, if the New York City default had an impact on aggregate interest rates, it was at most small and of short duration. [ABSTRACT FROM AUTHOR]

This paper proposes an ensemble predictor for the weekly increase in the number of confirmed COVID‐19 cases in the city of New York at zip code level. Within a Bayesian model averaging framework, the baseline is a Poisson regression for count data. The set of covariates includes autoregressive terms, spatial effects, and demographic and socioeconomic variables. Our results for the second wave of the coronavirus pandemic show that these regressors are more significant to predict the number of new confirmed cases as the pandemic unfolds. Both pointwise and interval forecasts exhibit strong predictive ability in‐sample and out‐of‐sample. [ABSTRACT FROM AUTHOR]

Climate change is disrupting our environment and business‐as‐usual practices will fail to reverse its impact. This paper focuses on the impact of the building sector and, in particular, it questions the energy and environmental benefits of advanced integrated and more conventional building‐applied photovoltaic (PV) systems, compared to a traditional municipality utility supply. A demonstration project named the ecological living module (ELM) is used to create a comparative life cycle assessment (LCA) of the adoption of these PV systems across three different climatic locations, namely New York City, London, and Nairobi. Findings show that, over the entire life cycle, the solar systems do better than the grid mix in reducing the building's dependence on nonrenewable resources. Unsurprisingly, in comparative terms, these systems do substantially better if the local grid mix is characterized by a predominantly nonrenewable energy profile. When comparing the two solar systems, the environmental impacts of the solar cells are negligible in the advanced system, whereas its structural components result in it being less environmentally friendly than the conventional solar PV. This highlights the possibility of future design iterations of these components to rethink their material ecology in terms of their life cycle—materiality, sourcing, and manufacturing, and so forth. The implications of this work suggest questioning, on a case‐by‐case basis, when and in what contexts integrated solar energy building systems are most plausible. This work also questions the scale at which grid scale distribution should occur. [ABSTRACT FROM AUTHOR]

During the last decade, while national homicide rates have remained flat, New York City has experienced a second great crime decline, with gun violence declining by more than 50 percent since 2011. In this paper, we investigate one potential explanation for this dramatic and unexpected improvement in public safety—the New York Police Department's shift to a more surgical form of "precision policing," in which law enforcement focuses resources on a small number of individuals who are thought to be the primary drivers of violence. We study New York City's campaign of "gang takedowns" in which suspected members of criminal gangs were arrested in highly coordinated raids and prosecuted on conspiracy charges. We show that gun violence in and around public housing communities fell by approximately one third in the first year after a gang takedown. Our estimates imply that gang takedowns explain nearly one quarter of the decline in gun violence in New York City's public housing communities over the last eight years. [ABSTRACT FROM AUTHOR]

Over 50,000 defendants are referred for competency to stand trial evaluations each year in the United States (Psychological evaluations for the courts: A handbook for mental health professionals and lawyers, New York, NY: The Guildford Press; 2018). Approximately 20% of those individuals are found by courts to be incompetent and are referred for "restoration" or remediation (Psychological evaluations for the courts: A handbook for mental health professionals and lawyers, 4th edn. New York, NY: The Guildford Press; 2018; Bull Am Acad Psychiatry Law. 1991;19:63–9). The majority of those incompetent defendants meet criteria for psychotic illnesses (J Am Acad Psychiatry Law. 2007;35:34–43). Forensic mental health professionals frequently have such patients/defendants decline recommended treatment with psychotropic medication. For a significant minority of defendants diagnosed with psychotic disorders, treatment with medication is thought to be necessary to restore their competency to stand trial. Without psychiatric intervention to restore competency, defendants may be held for lengthy and costly hospitalizations while criminal proceedings are suspended. In these situations, clinicians are guided by the Supreme Court decision, Sell v. United States (2003). The Sell opinion describes several clinical issues courts must consider when determining whether a defendant can be treated involuntarily solely for the purpose of restoring his/her competency. This paper offers some guidance to clinicians and evaluators who are faced with making recommendations or decisions about involuntary treatment. Using a question and answer format, the authors discuss data that support a decision to request, or not request, court authorization for involuntary treatment. Specifically, eight questions are posed for forensic evaluators to consider in determining the prognosis or viability of successful treatment and restoration. Finally, a clinical vignette is also presented to highlight important factors to consider in Sell‐related evaluations. [ABSTRACT FROM AUTHOR]

This paper examines New York City's Summer Youth Employment Program (SYEP). SYEP provides jobs to youth ages 14–24, and due to high demand for summer jobs, allocates slots through a random lottery system. We match student‐level data from the SYEP program with educational records from the NYC Department of Education and use the random lottery to estimate the effects of SYEP participation on a number of academic outcomes, including test taking and performance. We find that SYEP participation has positive impacts on student academic outcomes, and these effects are particularly large for students who participate in SYEP multiple times. [ABSTRACT FROM AUTHOR]

COVID‐19 has extraordinarily impacted every facet of the health care facilities' operations. Various strategies and policies were implemented promptly to preserve resources, not only to provide medical care to the expected massive numbers of COVID‐19 patients, but also to mitigate the contagion spread at the workplace to ensure safety of healthcare workers. All routine, non‐essential medical services and procedures were ramped down and workers deemed non‐essential were directed to work remotely from home to reduce the number of people at hospital premises and preserve much needed personal protective equipment that were in short supply at the outset of the pandemic. The laboratories did not remain unscathed and were under immense pressure to maintain workplace safety while being operational and provide best patient care with limited resources. In this paper, we share our experience and challenges that we faced in a cytopathology laboratory at a major academic centre in New York, USA during the peak of infection. This study reviews the impact of COVID‐19 on cytopathology specimen numbers during the peak of pandemic in New York City. Most specimens decreased in number and proportion except for effusion cytology which almost doubled. The rate of malignant and indeterminate diagnostic categories significantly increased while the benign category decreased, and the non‐diagnostic category remained the same. Adaptations to staffing and clinical operations to provide continuous patient care and trainee education while maintaining workplace safety are described. [ABSTRACT FROM AUTHOR]

This paper examines the case of continuous budgeting both preadoption and postadoption in New York City and considers matters of forecast bias, rebudgeting, and the belief that New York City remains in structural deficit which has been cited as a continuing source of concern since New York City's 1970s fiscal crisis. The asserted structural deficit is a rationale for reducing spending in the prebudget and postbudget adoption periods. Williams (), shows that New York City's revenue forecasts are biased to underestimation, exacerbating over longer horizons. This paper examines expenditure estimates, reductions and within-year modifications over the first decade of the twenty-first century. If there is a structural deficit, expenditures would exceed revenues in forecasts by more than offsetting forecast biases. However, there are other reasons expenditures may exceed revenues in forecasts. Late term increases in expenditure estimates suggest deliberate choices, which cannot be termed 'structural.' Expenditure changes follow changing revenue particularly in the postadoption period. This rebudgeting practice does not reflect fiscal stress; it is part of a complex method of producing a surreptitious budget stabilization fund, reallocations favored by the mayor, and possibly shifting of the budget towards capital uses with little broad public discussion. These observed effects are somewhat consistent with effective financial management, but are nontransparent and inconsistent with democratic participation. Policy recommendations aim at restoring transparency and democratic oversight. [ABSTRACT FROM AUTHOR]

In the 40‐plus years since the Individuals with Disabilities Education Act, special education has grown in the number of students and amount spent on services. Despite this growth, academic performance of students with disabilities remains troublingly low compared to general education students. To some extent, these differences reflect persistent underlying disabilities, but they also may reflect ineffective services. Does special education improve academic outcomes for students with disabilities? There is surprisingly little evidence to guide policy and answer this question. This paper provides an answer for the largest disability group, students with specific learning disabilities (LDs), using rich New York City public school data. Because the majority of LDs are classified after school entry, we observe outcomes before and after classification, allowing us to estimate impacts using within‐student pre/post comparisons (student fixed effects) and an intent‐to‐treat specification. We find that academic outcomes improve for LDs following classification into special education and impacts are largest for those entering special education in earlier grades. Attendance, however, shows little change after classification. Results are robust to alternative specifications and falsification tests bolster confidence in a causal interpretation. Differences in impacts by gender, race/ethnicity, grade of classification, and settings illuminate possible mechanisms. [ABSTRACT FROM AUTHOR]

The aeronautical community is currently researching technology that might lead to commercial hypersonic aircraft that would cruise at Mach 5–8 in the middle or upper stratosphere and would transfer passengers from London to New York or from Los Angeles to Tokyo in just a couple of hours. Depending on the engine technology to be adopted, these aircraft will potentially release substantial amounts of water vapor and nitrogen oxides around 30–40 km altitude. We show here that the operation of a large fleet of such aircraft could potentially deplete considerable amounts of ozone in the stratosphere, which would lead to a substantial increase in biologically damaging ultraviolet radiation reaching the Earth's surface. The calculations are based on a specific emission scenario, which carries large uncertainties but can easily be scaled to account for the type of aircraft engine to be eventually adopted, improved technology to be expected, and the size and operation conditions of the future aircraft fleet. Plain Language Summary: Commercial hypersonic aircraft, if developed in the future, will be flying at Mach 5 to 8 in the middle to upper stratosphere (30 to 40 km altitude) to carry passengers in a couple of hours from London to New York or from Los Angeles to Tokyo. Depending on the adopted technology and fleet size, the powerful engines of such airplanes may release substantial amounts of water and nitrogen oxides in the stratosphere, which could potentially damage the protecting ozone layer and hence increase the level of biologically damaging ultraviolet radiation reaching the Earth surface. The paper uses an advanced global atmospheric model to assess the impact of a potential fleet of hypersonic aircraft. Key Points: Hypersonic transport (HST) releasing nitrogen oxides and water vapor have the potential to reduce the stratospheric ozone abundancePer Tg injection of nitrogen oxides, the calculated ozone depletion is larger for aircraft flying at 30 km than 40 km altitudeOzone decrease near the HST flight altitude is reduced by about a third when temperature and dynamical feedbacks are taken into account [ABSTRACT FROM AUTHOR]

This paper investigates skyscraper competition between New York City and Chicago. The urban economics literature is generally silent on strategic interaction between cities, yet skyscraper rivalry between these cities is a part of U.S. historiography. This paper tests whether there is, in fact, strategic interaction across cities. First, I find that each city has positive reaction functions with respect to the other city, suggesting strategic complementarity. In regard to zoning, I find that height regulations negatively impacted each city, but produced positive responses by the other city, providing evidence for strategic substitutability.

DECISION making ,SMALL group research ,SMALL groups - Abstract
The system dynamics group at the Rockefeller College of the University at Albany has been developing techniques to create system dynamic models with groups of managers during the last 25 years. Building upon their tradition in decision conferencing, the group has developed a particular style that involves a facilitation team in which people play different roles. Throughout these years of experience, the group has also developed several “scripts” to elicit knowledge from experts based on small-groups research, and well-established practices in the development of system dynamics models. This paper constitutes a detailed documentation of a relatively small-scale modeling effort that took place in early 2001, offering a “soup to nuts” description of group model building at Albany. The paper describes in detail nine of the scripts that the group has developed, offering some reflections about their advantages and limitations. Copyright © 2006 John Wiley & Sons, Ltd.

Objective: To compare the clinical outcomes of a modified arthroscopic triple‐row (TR) repair technique with the suture bridge (SB) repair technique in treating L‐shaped delaminated rotator cuff tears. Various surgical techniques for L‐shaped delaminated rotator cuff tears have been reported, many of which aid in increasing the contact area and pressure of the rotator cuff. However, there is still debate over which technique yields superior results. Methods: From January 2017 to March 2020, 61 cases of L‐shaped delaminated rotator cuff tears were included in this study. Of these, 34 cases underwent the modified arthroscopic triple‐row repair technique, while 27 cases were addressed with the suture bridge repair technique. Functional assessment was conducted using the American Shoulder and Elbow Surgeons (ASES) score, the University of California Los Angeles (UCLA) shoulder score, the Constant score (CS), and the visual analogue scale (VAS) score. Magnetic Resonance Imaging (MRI) assessments for rotator cuff healing were performed at the 24‐month postoperative mark. Statistical evaluations were conducted using SPSS for Windows (Version 25.0, IBM, Armonk, NY, USA), employing the Wilcoxon signed‐rank test to compare preoperative and postoperative data and ROM differences, and the Mann–Whitney U test for statistical differences in clinical outcome scores between the two groups. A p‐value of less than 0.05 was considered statistically significant. Results: Comparative analysis of the preoperative and final follow‐up scores revealed a substantial enhancement in shoulder function, as indicated by the ASES, UCLA, CS, and VAS scores, with statistical significance (p < 0.001). At both the preoperative stage and final follow‐up, no notable differences were observed in ASES, UCLA, CS, and VAS scores between the two groups. However, the TR repair group exhibited lower VAS scores than the SB group at 1 and 3 months postoperatively. Active range of motion (ROM) showed significant improvement in both groups. No significant differences in ROM were noted between the two groups either before the surgery or at the final follow‐up. Conclusion: The study demonstrates that both the modified arthroscopic TR and SB techniques for L‐shaped delaminated cuff tears yield satisfactory outcomes, with no significant differences in overall clinical performance. Notably, early postoperative pain management appears more effective with the modified TR technique, suggesting its potential for enhanced early recovery experiences. This technique's design, promoting securer fixation and optimal contact conditions, is implied to facilitate superior long‐term healing, warranting further investigation into its long‐term benefits.

SUMMARY This paper discusses modelling, analysis and design issues for a 55-storey hotel building recently planned for New York City, USA. The lateral force resistance of the investigated building primarily makes use of exterior reinforced concrete shear walls in one direction and exterior reinforced concrete moment frames in the other direction, in which tube action credited to the connection of the walls and frames was designed to play a significant role in the lateral stiffness and strength. In addition, a full-storey belt wall system, enclosing the entire perimeter of the building at approximately the mid-height, is expected to provide a considerable contribution to the lateral force resistance. In this paper, the contribution of tube action and the belt wall system to structural behaviour is investigated in terms of quantitative measures such as lateral drift, building dynamic properties and flange frame contribution to overturning moment resistance. In addition, axial force distribution among the various vertical members under lateral forces is discussed for each of the two principal building directions. Finally, the seismic behaviour of the investigated building is qualitatively discussed in order to propose a seismic force-resisting system classification into which this concrete tube system would fit.

MUNICIPAL revenue ,FORECASTING ,DECISION making ,BUDGET deficits ,PUBLIC spending - Abstract
This paper examines the impact of forecasters, horizons, revenue categories, and forecast timing in relation to decision making on forecast bias or accuracy. The significant findings are: for the most part forecasters tend to report forecasts that are similar rather than competitive. Forecast bias (underforecasting) increases over longer horizons; consequently claims of structural budget deficit are suspect, as an assertion of structural deficit requires that a reliable forecast of revenue shows continuous shortfall compared with a reliable forecast of expenditures. There is an overforecasting bias in property tax, possibly reflecting demand for services. There is an underforecasting forecast bias in two revenue categories, all other taxes and federal categorical grants, resulting in a net total underforecasting bias for the city's revenue. There appears to be a period effect (forecasts in June are substantially biased), but this effect requires further study. The study suggests further examination of the bias associated with revenue categories, time within the budget cycle, and forecast horizon. [ABSTRACT FROM AUTHOR]

This paper evaluates the relationship among the NYMEX futures prices for crude oil, unleaded gasoline, heating oil and the US trade-weighted exchange rate. The motivation is to update and extend the literature in an attempt to determine the relationship between the US exchange rate and energy prices. In addition, the causal relationships among the energy futures prices are examined. Cointegration is detected among the variables, but contrary to the existing empirical literature, it is found that the US exchange rate can be excluded from the cointegrating space. The Granger causality tests and impulse response functions also indicate that the US exchange rate is not related to the energy prices. The recursive cointegration analysis reveals that the relationship between the US exchange rate and the energy futures prices has faded across time. [ABSTRACT FROM AUTHOR]

This paper discusses practical modeling issues pertinent to the design of an irregularly shaped reinforced concrete (RC) high-rise building currently under development in New York City. The structure analyzed consists of a 60-storey residential tower and a 25-storey hotel building structurally connected to each other. For the seismic force resistance, a dual system combining ordinary RC shear walls and intermediate slab-column moment frames was used at the upper portion, while a building frame system of ordinary RC shear walls was used at the lower portion of the structure. A variety of models were used to simulate the behavior of various elements of the structure, with special attention given to overall systemic effects of different member stiffness considered to account for distinct stress levels under service and ultimate loads. The models used the slab-column frames and shear walls were verified by comparing with other available models or laboratory tests. The in-plane flexibility of floor diaphragms at the interface between the two substructures with different geometries was simulated to identify the most critical wind conditions for each structural member. Finally, building dynamic analyses were performed to demonstrate the modeling issues to be considered for the lateral force design of irregular high-rise buildings. [ABSTRACT FROM AUTHOR]

Aims and objectives. To describe and analyse the nurses’ role in responding to the influenza epidemic in New York City in 1918. Background. Today the world is facing the threat of pandemic avian influenza and there is renewed interest in lessons learned from the influenza pandemic of 1918, one of the deadliest disease outbreaks recorded in history. Much of the published history has been written from a medical or military perspective. No comprehensive account of nursing’s role has been written. Design. A social history framework was used. Methods. Traditional historical methods were used for data collection, data immersion, the development of a chronology and themes. Critical analysis of social, political and economic context was also done. Primary sources included the Lillian D. Wald papers at the New York Public Library, newspapers, journal articles and other archival data. Results. In 1918, New York City nurses provided care to thousands of patients. They did so with minimal federal support, relying on local community agencies to establish makeshift hospitals and provide soup kitchens. The Henry Street Visiting Nurses, assisted by numerous social agencies and Red Cross volunteers, visited patients in their homes and provided them with the only treatment there was: nursing care. Conclusions. In 1918, immediate cooperation among a previously established network of nursing and other social organisations and prompt cooperation with the American Red Cross and the United States Public Health Service was essential to New York City’s response to the crisis. Relevance to clinical practice. Should an influenza pandemic occur today, as many as a billion people could fall ill. Shortages of antiviral drugs, the speed with which the pandemic could occur and its widespread effects are such that nursing, public health and medical professionals will need to rely on local personnel and supplies. Immediate cooperation and collaboration among federal, state and local organizations will be essential to the response. [ABSTRACT FROM AUTHOR]

This paper examines experiences of gentrification from the perspective of young working class women of color who have grown up on the Lower East Side of New York City in the 1980s and 90s. In a participatory action research project entitled 'Makes Me Mad: Stereotypes of young urban womyn of color', six young women researchers investigate the relationship between the gentrification of their community, public (mis)representations, and their self-understanding. Focusing on how young women negotiate processes of disinvestment and gentrification, this paper offers insights into how globalization is worked out on the ground and in their everyday lives. Bridging the material and psychological, I explore the socio-spatial constitution of young women's identities as they interpret their experiences growing up on the Lower East Side having to live up both to the grittyness of ghetto life and the glamour of the club, café and boutique life. Drawing connections between the white-washing sweep of gentrification, and socioeconomic disinvestment of their community, the women express a nuanced understanding of neighborhood change. I maintain that we can learn about the contradictions of globalization from these young women's ambivalent relationship with neighborhood change. [ABSTRACT FROM AUTHOR]

Few communities welcome federally subsidized rental housing, with one of the most commonly voiced fears being reductions in property values. Yet there is little empirical evidence that subsidized housing depresses neighborhood property values. This paper estimates and compares the neighborhood impacts of a broad range of federally subsidized rental housing programs, using rich data for New York City and a difference-in-difference specification of a hedonic regression model. We find that federally subsidized developments have not typically led to reductions in property values and have, in fact, led to increases in some cases. Impacts are highly sensitive to scale, though patterns vary across programs. © 2007 by the Association for Public Policy Analysis and Management [ABSTRACT FROM AUTHOR]

Nonprofit organizations play a critical role in U.S. housing policy, a role typically justified by the claim that their housing investments produce significant neighbor-hood spillover benefits. However, little work has actually been done to measure these impacts on neighborhoods. This paper compares the neighborhood spillover effects of city-supported rehabilitation of rental housing undertaken by nonprofit and for-profit developers, using data from New York City. To measure these benefits, we use increases in neighboring property values, estimated from a difference-in-difference specification of a hedonic regression model. We study the impacts of about 43,000 units of city-supported housing completed during the 1980s and 1990s, and our sample of property transactions includes nearly 300,000 individual sales. We find that both nonprofit and for-profit projects generate significant, positive spillover effects. This finding in itself is significant, given the widespread skepticism about the impact of subsidized housing on neighborhoods. We also find some differences across sectors. First, the impact of nonprofit housing remains stable over time, whereas the effect of for-profit housing declines slightly with time. Second, while large for-profit and nonprofit developments deliver similar benefits, in the case of small projects, for-profit developments generate greater impacts than their nonprofit counterparts. These differences are consistent with theoretical predictions. In particular, in the presence of information asymmetries with respect to housing quality, the non-distribution constraint should lead nonprofits to invest more than for-profits in developing and maintaining features that benefit the broader community. Meanwhile, the fact that scale makes a difference to nonprofit impacts may reflect the capacity constraints often faced by smaller nonprofits. ©2006 by the Association for Public Policy Analysis and Management [ABSTRACT FROM AUTHOR]

ABSTRACT Midtown Manhattan is the largest business district in the country. Yet only a few miles to the south is another district centered at Wall Street. This paper aims to investigate when and why midtown emerged as a separate business district. We have created a new data set from historical New York City directories that provide the employment location, residence, and job type for several thousand residents in the late-19th and early-20th centuries. We supplement this data with additional records from historical business directories. The evidence suggests that early midtown firms appeared there in order to be closer to local residential customers who had been moving north on the island throughout the 19th century. Once several industries appeared in midtown, it triggered a spatial equilibrium readjustment in the 1880s, which then promoted the rise of skyscrapers in midtown around the turn of the 20th century. This process occurred several years before the opening of Grand Central Station in 1913. [ABSTRACT FROM AUTHOR]

HURRICANE Sandy, 2012 ,FLOODS - Abstract
In this paper, we describe a new method of modeling coastal inundation arising from storm surge by coupling a widely used storm surge model (ADCIRC) and an urban flood inundation model (FloodMap). This is the first time the coupling of such models is implemented and tested using real events. The method offers a flexible and efficient procedure for applying detailed ADCIRC storm surge modeling results along the coastal boundary (with typical resolution of ∼100 m) to FloodMap for fine resolution inundation modeling (<5 m). The coastal inundation during Hurricane Sandy was simulated at both the city (New York City) and subregional (lower Manhattan) scales with various resolutions. Results obtained from the ADCIRC and coupled ADCIRC-FloodMap simulations were compared with the recorded (high water marks) and derived (inundation extent based on the planar method) data from FEMA. At the city scale, coupled ADCIRC-FloodMap modeling demonstrates improved prediction over ADCIRC modeling alone for both the extent and depth of inundation. The advantage of the coupled model is further illustrated in the subregional modeling, using a mesh resolution of 3 m which is substantially finer than the inland mesh resolution used by ADCIRC (>70 m). In further testing, we explored the effects of mesh resolution and roughness specification. Results agree with previous studies that fine resolution is essential for capturing intricate flow paths and connectivity in urban topography. While the specification of roughness is more challenging for urban environments, it may be empirically optimized. The successful coupling of ADCIRC and FloodMap models for fine resolution coastal inundation modeling unlocks the potential for undertaking large numbers of probabilistically based synthetic surge events for street-level risk analysis.

GENTRIFICATION ,URBAN renewal ,URBAN sociology - Abstract
Inner city gentrification is widely recognized as an international phenomenon and yet little research has been carried out into its incidence, manifestations and effects at a transnational level. The main objective of the paper is to adopt such an approach comparing the context of gentrification in three of the largest cities that have been affected, New York, London in England and Paris in France. It considers the evolutionary processes of gentrification, the stages through which gentrified neighborhoods in these cities have passed. Taking an international comparative approach, it attempts to establish whether there are certain processes that are prerequisites for the gentrification process, or whether the processes associated with gentrification in the three cities are more locally contextual. The paper aims to contribute to the discourse on gentrification by analyzing the process internationally in more depth than the literature to date, offering a genuinely comparative analysis. In acknowledging contextual differences, one can offer constructive comparative observations of the various stages in the gentrification process which will allow to consider gentrification as an international process.

INTRODUCTION: South Asian (SA) and East Asian (EA) older adults represent the fastest‐growing racial/ethnic groups of Americans at risk for dementia. While recruiting older SA adults into a brain health study, we encountered unexpected hesitancy toward structural brain magnetic resonance imaging (MRI) analysis and stigmatizing attitudes related to internal locus of control (LoC) for future dementia risks. We hypothesized that support for MRI‐related research was influenced by these attitudes as well as personal MRI experience, perceived MRI safety, and concerns for personal risk for future dementia/stroke. METHODS: We developed a brief cross‐sectional survey to assess older adults' MRI experiences and perceptions, desire to learn of six incidental findings of increasing impact on health, and attitudes related to dementia (including LoC) and research participation. We recruited a convenience sample of 256 respondents (74% reporting as 50+) from the New Jersey/New York City area to complete the survey (offered in English, Chinese, Korean, and Spanish) and modeled the proportional odds (PO) for favorable attitudes toward research activities. RESULTS: Seventy‐seven SA and 84 EA respondents were analyzed alongside 95 White, Black, or Hispanic adults. White (PO = 2.54, p = 0.013) and EA (PO = 2.14, p = 0.019) respondents were both more likely than SA respondents to endorse healthy volunteers' participation in research, and the difference between White and SA respondents was mediated by the latter's greater internal LoC for dementia risks. EA respondents had more worries for future dementia/stroke than SA respondents (p = 0.006) but still shared SA respondents' lower wish (measured by proportion of total) to learn of incidental MRI findings. DISCUSSION: SA—and EA compared to SA—older adults had low desire to learn of incidental MRI findings but had different attitudes toward future dementia/stroke risks. A culturally appropriate protocol to disclose incidental MRI findings may improve SA and EA participation in brain health research. Highlights: Older Asian Americans have limited interest in incidental findings on research MRISouth Asians are most likely to attribute dementia to people's own behaviorsSouth Asians' attitudes mediate lower support for healthy volunteers in researchSouth and East Asians differ in dementia worries and research‐related attitudes [ABSTRACT FROM AUTHOR]

The research reported in this paper studied 240 rural youths in four central New York high schools. It investigated (1) the relationship between value orientations and the education and occupation choice-making process, and (2) the structural antecedents of those value orientations. Choice making was classified in two levels: aspirations and plans. An instrument was constructed which aimed at ranking individuals on a latent continuum for each of twelve values. The findings support the general hypothesis that in the education and occupation decision process there is a relationship between an individual's value orientations and the choice that an individual makes from among the alternatives available. The findings further suggest that the influence of values on choices decreases as freedom of opportunity is restricted by the bonds of social structure. [ABSTRACT FROM AUTHOR]
