103. Pathways for Assessing Interdisciplinarity: A Systematic Review
- Author
-
Laursen, Bethany K., Motzer, Nicole, and Anderson, Kelly J.
- Abstract
In many sectors and in many respects, interdisciplinarity has made progress in recent decades, but less so when it comes to evaluating interdisciplinary work. Challenges remain, especially regarding what counts as 'good' interdisciplinarity. While previous reviews describe broad trends contributing to these challenges, high-level observations are less suited to: (1) pinpointing underlying sources of persistent evaluative issues, (2) capturing less frequent counterexamples and emerging trends, and (3) providing practical guidance for moving the field forward. This article presents a novel approach for excavating and analyzing assessment designs within and across a wide range of published studies. It is the first study to structure its review of interdisciplinary evaluation around the basics of evaluation theory, creating a simplified model of assessment design choices called an "assessment pathway." It further stands alone as an extensive systematic review of the interdisciplinary literature uniquely placed within the context of evaluation, encompassing 20 years, 142 studies, 1,006 assessment pathways, and 19,114 data points. Results show that while interdisciplinary assessments to date excel at variation, only 12% of identified pathways contain the minimum elements required to reach an evaluative judgment. Increased attention to evaluation theory can catalyze progress and provide structure and shared language to a highly varied domain.

104. The Interchangeability of Liking and Friend Nominations to Measure Peer Acceptance and Friendship

- Abstract
Two studies examine the convergence between measures of friendship and measures of liking in the assessment of friendship and peer acceptance. In the first study, 551 (301 boys and 250 girls) Canadian primary school children (ages 8-11) nominated friends and liked-most classmates. In the second study, 282 (127 boys and 155 girls) US primary school children (ages 9-11) nominated friends and rated classmates on a sociometric preference scale. The results revealed considerable convergence in the assessment of friendship. Most first, second, and third ranked friends were also nominated and rated as liked-peers, suggesting that when measures of liking are used to identify friends, few top-ranked friendships are overlooked. There was less convergence in assessments of peer acceptance. Peer acceptance scores derived from friend nominations were more strongly correlated with peer acceptance scores derived from liking nominations than with those derived from sociometric preference ratings. We conclude that liking nominations accurately capture friendships, particularly best friendships. Friend nominations may be a suitable substitute for assessments of liking, but they are a poor substitute for assessments of sociometric preference.

105. Exploring Two-Year College Biology Instructors' Preferences around Teaching Strategies and Professional Development
- Author

Wise, Sarah B., Archie, Tim, and Laursen, Sandra
- Abstract
Nearly half of all college students and the majority of college students of color begin their studies at 2-year colleges. The educational quality that these students experience will affect future success, but little research to date has focused on the professional development (PD) of their instructors. We offer an exploratory study on PD needs and preferences of ten 2-year college biology instructors who have experience with evidence-based instructional practices. Using a literature review and interview data, we address four research questions. We contextualize the interview results by describing interviewee teaching styles and their teaching and inclusion strategies, drawing on categorizations from education research literatures in and beyond biology. We then summarize interviewee experiences, preferences, and recommendations for PD. Most interviewees preferred PD that could be readily applied to their courses and included follow-up community support. While our purposive sample is limited, we note high levels of interest in PD supporting inclusive pedagogy and non-biology learning goals, such as study skills, metacognition, and quantitative skills. We describe implications for inclusive design of biology instructor PD.

109. What Does It Mean to Be Susceptible to Influence? A Brief Primer on Peer Conformity and Developmental Changes That Affect It
- Author
-
Laursen, Brett and Faur, Sharon
- Abstract
Peer influence is a twofold process that entails a behavior by an agent of influence that elicits conformity from the target of influence. Susceptibility describes the likelihood that conformity will occur. This review focuses on factors that shape susceptibility to peer influence. We argue that conformity has two distinct sources. In some instances, conformity is a product of characteristics of the target of influence, operationalized as stable individual difference variables. Trait-like attributes associated with susceptibility to peer influence include conformity dispositions, social goals, resource acquisition strategies, vulnerabilities, and maturational status. In other instances, conformity is a product of the context in which the target is situated, operationalized as impermanent individual difference variables. State-like circumstances associated with susceptibility to peer influence include conditions of uncertainty, personal attributes that differ from the partner or group, perceived benefits of impression management, unmet social needs, and social referents and beliefs about their behavior. Empirical illustrations are provided. We close with a discussion of developmental changes hypothesized to impact variations in susceptibility to peer influence.

110. Assessing Peer Influence and Susceptibility to Peer Influence Using Individual and Dyadic Moderators in a Social Network Context: The Case of Adolescent Alcohol Misuse
- Author
-
DeLay, Dawn, Burk, William J., and Laursen, Brett
- Abstract
Higher accepted friends are known to influence the alcohol misuse of lower accepted friends, but not the reverse. The present study was designed to address the origins of this influence: Are higher accepted friends particularly "influential" or are lower accepted friends particularly "susceptible" to influence? To address this question, we introduce an innovative application of longitudinal social network techniques (RSIENA) designed to distinguish being influential from being susceptible to influence. The results revealed that influence was a product of heightened susceptibility among low accepted adolescents, rather than heightened influence among high accepted adolescents. The findings are consistent with claims that low accepted youth fear the consequences of nonconformity and adjust their behavior to more closely resemble their affiliates.

111. Constraints on the Use of the Memorizing Effort Heuristic
- Author

Laursen, Skylar J. and Fiacconi, Chris M.
- Abstract
Despite the naïve intuition that individuals' confidence in their future memory performance should increase with longer self-paced study time, it is commonly observed that the relation between invested study time and memory predictions (i.e., judgments of learning (JOLs)) is negative. This negative relation has been suggested to reflect use of the "memorizing effort heuristic," whereby participants infer that items that require more effort to learn are less likely to be subsequently remembered. Here, we report the results of two experiments along with a re-analysis of a prior published dataset (Laursen & Fiacconi, "Memory & Cognition," 49(3), 498-517, 2021) that place constraints on our current understanding of individuals' use of the memorizing effort heuristic. In Experiment 1 we presented difficult word pairs either in isolation or intermixed with relatively easier items to assess the impact of list context on individuals' use of the memorizing effort heuristic. Our results showed that in the presence of relatively easier items the negative relation between study time and JOLs for difficult items was absent. In Experiment 2, we sought to determine whether this same context-dependent shift also applied to individuals' predictions for others' memory performance. Interestingly, we found that, although individuals did apply the memorizing effort heuristic when making predictions regarding others' memory performance, they did not adapt their use of this heuristic in the same context-dependent manner as when they predict their own memory performance. Together, these findings point to the need for a more sophisticated understanding of the interplay between data-driven and goal-driven regulation of self-directed learning.

112. Combining Meta-Epidemiological Study Datasets on Commercial Funding of Randomised Clinical Trials: Database, Methods, and Descriptive Results of the COMFIT Study

- Abstract
Randomised trials are often funded by commercial companies and methodological studies support a widely held suspicion that commercial funding may influence trial results and conclusions. However, these studies often have a risk of confounding and reporting bias. The risk of confounding is markedly reduced in meta-epidemiological studies that compare fairly similar trials within meta-analyses, and risk of reporting bias is reduced with access to unpublished data. Therefore, we initiated the COMmercial Funding In Trials (COMFIT) study aimed at investigating the impact of commercial funding on estimated intervention effects in randomised clinical trials based on a consortium of researchers who agreed to share meta-epidemiological study datasets with information on meta-analyses and trials included in meta-epidemiological studies. Here, we describe the COMFIT study, its database, and descriptive results. We included meta-epidemiological studies with published or unpublished data on trial funding source and results or conclusions. We searched five bibliographic databases and other sources. We invited authors of eligible meta-epidemiological studies to join the COMFIT consortium and to share data. The final construction of the COMFIT database involves checking data quality, identifying trial references, harmonising variable categories, and removing non-informative meta-analyses as well as correlated meta-analyses and trial results. We included data from 17 meta-epidemiological studies, covering 728 meta-analyses and 6841 trials. Seven studies (405 meta-analyses, 3272 trials) had not published analyses on the impact of commercial funding, but shared unpublished data on funding source. On this basis, we initiated the construction of a combined database. Once completed, the database will enable comprehensive analyses of the impact of commercial funding on trial results and conclusions with increased statistical power and a markedly reduced risk of confounding and reporting bias.

113. Thinking with Klein about Integration
- Author

Laursen, Bethany and O'Rourke, Michael
- Abstract
Integration is crucial to interdisciplinary and transdisciplinary work and it therefore deserves perennial attention by scholars and practitioners of such work. Few have thought so carefully, deeply, and tenaciously about integration as Julie Thompson Klein. In this article, we recount the development of Klein's thinking on integration, from her early stepwise model in 1990 to her current socio-linguistic model. After summarizing Klein's views, we compare the socio-linguistic model to a more recent view of integration known as the IPO (input-process-output) model. We show how these two models of integration relate to one another, and then we demonstrate their complementarity using an example of integrative argumentation from a Toolbox workshop. We conclude that we can understand instances of cross-disciplinary integration better with both models than with only one or the other. This theoretical stereoscope opens new avenues of research about the types of integrative relations collaborators use, what is involved in social/rhetorical integration, and the extent to which it is feasible to specify all of the parameters in an instance of integration.

Hepatitis A ,acute inflammatory demyelinating polyneuropathy ,Guillain-Barré syndrome - Abstract
Introduction: Acute inflammatory demyelinating polyneuropathy (AIDP) is characterized by progressive, mild sensory symptoms and progressive areflexic weakness. It typically follows a gastrointestinal or respiratory infection but has rarely been described after acute viral hepatitis.Case Report: This is the case of a 59-year-old male who presented to the emergency department after acutely developing progressive neurologic symptoms following a hospitalization for acute hepatitis A. Cerebrospinal fluid analysis revealed albuminocytologic dissociation, and cervical spine magnetic resonance imaging revealed nerve root enhancement.Discussion: The patient was diagnosed with AIDP, which is the most common subtype of Guillain-Barré syndrome in the United States and Europe. There have been few previously reported cases of AIDP following acute hepatitis A infection.

Quantitative Biology - Neurons and Cognition - Abstract
Reading saccades that occur within a single line of text are guided by the size of letters. However, readers occasionally need to make longer saccades (known as return-sweeps) that take their eyes from the end of one line of text to the beginning of the next. In this study, we tested whether return-sweep saccades are also guided by font size information and whether this guidance depends on visual acuity of the return-sweep target area. To do this, we manipulated the font size of letters (0.29 vs 0.39 deg. per character) and the length of the first line of text (16 vs 26 deg.). The larger font resulted in return-sweeps that landed further to the right of the line start and in a reduction of under-sweeps compared to the smaller font. This suggests that font size information is used when programming return-sweeps. Return-sweeps in the longer line condition landed further to the right of the line start and the proportion of under-sweeps increased compared to the short line condition. This likely reflects an increase in saccadic undershoot error with the increase in intended saccade size. Critically, there was no interaction between font size and line length. This suggests that when programming return-sweeps, the use of font size information does not depend on visual acuity at the saccade target. Instead, it appears that readers rely on global typographic properties of the text in order to maintain an optimal number of characters to the left of their first fixation on a new line.

Physics - Chemical Physics - Abstract
Disentangling the dynamics of electrons and nuclei during nonadiabatic molecular transformations remains a considerable experimental challenge. Here we have investigated photoinduced electron transfer dynamics following a metal-to-ligand charge-transfer (MLCT) excitation of the [Fe(bmip)2]2+ photosensitizer, where bmip = 2,6-bis(3-methyl-imidazole-1- ylidine)-pyridine, with simultaneous femtosecond-resolution Fe K{\alpha} and K\b{eta} X-ray Emission Spectroscopy (XES) and Wide Angle X-ray Scattering (WAXS). This measurement clearly shows temporal oscillations in the XES and WAXS difference signals with the same 278 fs period oscillation. The oscillatory signal originates from an Fe-ligand stretching mode vibrational wavepacket on a triplet metal-centered (3MC) excited state surface. The vibrational wavepacket is created by 40% of the excited population that undergoes electron transfer from the non-equilibrium MLCT excited state to the 3MC excited state with a 110 fs time constant, while the other 60% relaxes to a 3MLCT excited state in parallel. The sensitivity of the K{\alpha} XES spectrum to molecular structure results from core-level vibronic coupling, due to a 0.7% average Fe-ligand bond length difference in the lowest energy geometry of the 1s and 2p core-ionized states. These results highlight the importance of vibronic effects in time-resolved XES experiments and demonstrate the role of metal-centered excited states in the electronic excited state relaxation dynamics of an Fe carbene photosensitizer.

Astrophysics - Astrophysics of Galaxies - Abstract
We perform a comprehensive analysis of the redshift evolution of the rest-UV spectra of star-forming galaxies out to z~5. We combine new z~5 measurements of HI Ly$\alpha$ and low- and high-ionization interstellar metal absorption features with comparable measurements at z~2-4. We measure the equivalent widths of interstellar absorption features using stacked spectra in bins of Ly$\alpha$ equivalent width, performing corrections to Ly$\alpha$ strengths based on a model for the transmission of the intergalactic medium. We find a strong correlation between decreasing low-ionization absorption strength and increasing Ly$\alpha$ emission strength over the redshift range z~2-5, suggesting that both of these quantities are fundamentally linked to neutral gas covering fraction. At the highest Ly$\alpha$ equivalent widths, we observe evolution at $z\sim5$ towards greater Ly$\alpha$ emission strength at fixed low-ionization absorption strength. If we interpret the non-evolving relationship of Ly$\alpha$ emission strength and low-ionization line strength at z~2-4 as primarily reflecting the radiative transfer of Ly$\alpha$ photons, this evolution at z~5 suggests a higher intrinsic production rate of Ly$\alpha$ photons than at lower redshift. Our conclusion is supported by the joint evolution of the relationships among Ly$\alpha$ emission strength, interstellar absorption strength, and dust reddening. We perform additional analysis in bins of stellar mass, star-formation rate, UV luminosity, and age, examining how the relationships between galaxy properties and Ly$\alpha$ emission evolve towards higher redshift. We conclude that increasing intrinsic Ly$\alpha$ photon production and strong detection of nebular CIV emission (signaling lower metallicity) at z~5 indicate an elevated ionized photon production efficiency ($\xi_{\rm ion}$)., Comment: 20 pages, 17 figures, accepted for publication in MNRAS

Chronic pulmonary aspergillosis (CPA) is a chronic fungal infection of the lung associated with high morbidity and mortality. The CPA Research network (CPAnet) registry established in 2018 is an international multicenter collaboration aiming to improve CPA knowledge and patient care. This study's aim was to describe the data collection process and content of CPAnet registry with preliminary clinical data. In the CPAnet registry, clinical data are collected through a web-based questionnaire. Data include CPA phenotype, comorbidities, treatment, outcome, and follow-up from several international centers. An exemplary descriptive analysis was performed on 74 patients, who were registered online before April 2020. CPA patients were predominantly (72%) male, 39% had chronic obstructive pulmonary disease, and 68% had a history of smoking. Chronic cavitary pulmonary aspergillosis was the most common CPA subtype (62%). In 32 patients (52%), voriconazole was the preferred first-line therapy. The multicenter multinational CPAnet registry is a valuable approach to gather comprehensive data on a large study population and reflects real-world clinical practice rather than focusing on specific patient populations in more specialized centers. Additional CPA reference centers are being encouraged to join this promising clinical research collaboration.

- Abstract
Background: Most previous studies of teaching styles and reading skills have been cross-sectional. Longitudinal research is needed to clarify the direction of effects. The present longitudinal study examined the degree to which differences in teaching styles in the third grade predict the sixth-grade reading performance. The consistency of the findings was addressed by comparing results across students in two countries (Finland and Estonia). Methods: A total of 1,057 students (50.9% boys) were followed from the third to sixth grade. Teaching styles of third-grade teachers (N = 70) were examined as predictors of the development of reading (i.e., third-grade to sixth-grade reading fluency and comprehension). Results: Five patterns of third-grade teaching practices were found across two countries: "child-centred style," "teacher-directed style," "child-dominated style," "extreme child-centred style," and "mixed child-centred" and "teacher-directed style (mixed teaching style)." The mixed teaching style and the child-centred style in the third grade were related to the greatest increases in reading fluency from the third to sixth grade, over and above the contribution of age, gender and maternal education. Conclusions: The findings underscore the importance of the flexible use of child-centred and teacher-directed practices, which are both linked to the development of reading fluency during late primary school years.

120. Off on the Wrong Foot: Task Avoidance at the Outset of Primary School Anticipates Academic Difficulties and Declining Peer Acceptance

Laursen, Brett, Richmond, Ashley, Kiuru, Noona, Lerkkanen, Marja-Kristiina, and Poikkeus, Anna-Maija
- Abstract
The present study examined the academic antecedents of declining peer social status. Participants included 545 (311 boys, 234 girls) Finnish students followed from the 1st through the 4th grade (ages 6-8 at outset). Each year, teachers completed assessments of academic task avoidance and students completed standardized measures of reading and math achievement. Acceptance was assayed through peer nominations. Supporting the hypothesized model, the results indicated that a lack of interest and motivation at the outset of primary school leads to a downward spiral of academic difficulties and diminished peer acceptance. Specifically, academic task avoidance in 1st and 2nd grade anticipated declining math and reading achievement one year later, which in turn, anticipated decreases in peer acceptance the following year. The findings held after controlling for factors known to contribute to school and peer difficulties, such as friendlessness, school readiness, and emotional and behavioural problems.

- Abstract
Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children's speech to one another and foster their language abilities and how these processes may vary in children with hearing loss. We used new objective measurement approaches to identify and quantify children's vocalizations during social contact, as determined by children's proximity and mutual orientation. The contributions of peer vocalizations to children's future vocalizations and language abilities were examined in oral language inclusion classrooms containing children with hearing loss who use hearing aids or cochlear implants and their typically hearing peers. Across over 600 hours of recorded vocal interactions of 29 2.5-3.5 year olds (16 girls) in 3 cohorts of children in a classroom, we found that vocalizations from each peer on a given observation predicted a child's vocalizations to that same peer on the subsequent observation. Children who produced more vocalizations to their peers had higher receptive and expressive language abilities, as measured by a standardized end-of-year language assessment. In fact, vocalizations from peers had an indirect association with end-of-year language abilities as mediated by children's vocalizations to peers. These findings did not vary as a function of hearing status. Overall, then, the results demonstrate the importance of dyadic peer vocal interactions for children's language use and abilities.

123. Revisiting the Hypothesis That Friends Buffer against Diminished Self-Esteem Arising from Poor Quality Parent-Adolescent Relationships: A Replication Study
- Author

Laursen, Brett, Dickson, Daniel J., Boivin, Michel, Bowker, Julie C., Brendgen, Mara, and Rubin, Kenneth H.
- Abstract
This replication study revisited conclusions from 2 previous investigations (Gauze, Bukowski, Aquan-Assee, & Sippola, 1996; van Aken & Asendorpf, 1997), which suggested that support from friends buffers against diminished self-esteem arising from poor quality relationships with mothers during the transition into adolescence. The aim of this replication study was to conduct an independent test of these findings with both concurrent and longitudinal data. Concurrent data for replication analyses were drawn from 4 projects, involving a total of 959 boys and 1,119 girls (ages 10 to 14) from Canada and the United States. Three samples reported participant ethnic descent: Africa (12.1%), Asia (5.6%), Europe (65.3%), Latin America (12.1%), and Native North America (0.9%). Child and mother reports of mother-child relationship quality assayed (a) maternal social support (in 3 data sets), and (b) family cohesion and adaptability (in 2 data sets). Main effects were replicated but hypothesized buffering effects were not. Maternal social support and friend social support were independently associated with adolescent self-esteem, concurrently, but not longitudinally. Family cohesion (but not adaptability) was associated with adolescent self-esteem, concurrently and longitudinally. Friend social support did not moderate associations between mother-child relationship quality and adolescent self-esteem, concurrently or longitudinally. The findings are consistent with a cumulative effects model wherein friends uniquely contribute to adolescent self-worth, over and above the contribution of mothers. The findings do not support claims that friends moderate associations between mother-child relationship quality and adolescent self-esteem.

127. When Seeing Is Believing: Generalizability and Decision Studies for Observational Data in Evaluation and Research on Teaching

Weston, Timothy J., Hayward, Charles N., and Laursen, Sandra L.
- Abstract
Observations are widely used in research and evaluation to characterize teaching and learning activities. Because conducting observations is typically resource intensive, it is important that inferences from observation data are made confidently. While attention focuses on interrater reliability, the reliability of a single-class measure over the course of a semester receives less attention. We examined the use and limitations of observation for evaluating teaching practices, and how many observations are needed during a typical course to make confident inferences about teaching practices. We conducted two studies based on generalizability theory to calculate reliabilities given class-to-class variation in teaching over a semester. Eleven observations of class periods over the length of a semester were needed to achieve a reliable measure, many more than the one to four class periods typically observed in the literature. Findings suggest practitioners may need to devote more resources than anticipated to achieve reliable measures and comparisons.

128. On the Intersection of Interdisciplinary Studies and Argumentation Studies: The Case of Inference to the Best Explanation

Laursen, Bethany K.
- Abstract
This article aims to convince readers of the value of intersecting the scholarship of interdisciplinarity with the field of argumentation studies. The interdisciplinarity literature has not much engaged with the vehicle that carries interdisciplinary learning, languages, and locutions: the argument. On the argumentation studies side, despite the diverse interests of these scholars, not many have studied how reasoning proceeds in interdisciplinary inquiries. To aid bridge-building from both sides, I use the example of interdisciplinary abductive reasoning to show how the two fields can benefit from each other. The article proceeds as thin, comparative case studies thickened by theory. By analyzing two extended cases of inquiry cast in Douglas Walton's argumentation terms, I argue Walton's model is necessary but not sufficient for understanding and dealing with the unique challenges of interdisciplinary abduction. I propose, instead, we add the PEPR model (Pattern Recognition, Explanation Imagination, Pattern Matching, and Reporting) to help us focus on the data to be explained while we lean on Walton's model to understand the people doing the explaining. I conclude argumentation studies and interdisciplinary theory can be mutually enlightening.

ESA operates the Sentinel-1 satellites, which provides Synthetic Aperture Radar (SAR) data of Earth. Recorded Sentinel-1 data have shown a potential for remotely observing and monitoring local conditions on broad acre fields. Remote sensing using Sentinel-1 have the potential to provide daily updates on the current conditions in the individual fields and at the same time give an overview of the agricultural areas in the region. Research depends on the ability of independent validation of the presented results. In the case of the Sentinel-1 satellites, every researcher has access to the same base dataset, and therefore independent validation is possible. Well documented research performed with Sentinel-1 allow other research the ability to redo the experiments and either validate or falsify presented findings. Based on current state-of-art research we have chosen to provide a service for researchers in the agricultural domain. The service allows researchers the ability to monitor local conditions by using the Sentinel-1 information combined with a priori knowledge from broad acre fields. Correlating processed Sentinel-1 to the actual conditions is still a task the individual researchers must perform to benefit from the service. In this paper, we presented our methodology in translating sentinel-1 data to a level that is more accessible to researchers in the agricultural field. The goal here was to make the data more easily available, so the primary focus can be on correlating and comparing to measurements collected in the broadacre fields. We illustrate the value of the service with three examples of the possible application areas. The presented application examples are all based on Denmark, where we have processed all sentinel-1 scan from since 2016., Comment: 9 pages, 5 figures, conference (AGENG2018)

Astrophysics - Astrophysics of Galaxies - Abstract
We present the detection analysis of a diffuse molecular cloud at z$_{abs}$=2.4636 towards the quasar SDSS J1513+0352(z$_{em}\,\simeq$ 2.68) observed with the X-shooter spectrograph(VLT). We measure very high column densities of atomic and molecular hydrogen, with log N(HI,H$_2$)$\simeq$21.8,21.3. This is the highest H$_2$ column density ever measured in an intervening damped Lyman-alpha system but we do not detect CO, implying log N(CO)/N(H$_2$) < -7.8, which could be due to a low metallicity of the cloud. From the metal absorption lines, we derive the metallicity to be Z $\simeq$ 0.15 Z$_{\odot}$ and determine the amount of dust by measuring the induced extinction of the background quasar light, A$_V$ $\simeq$ 0.4. We also detect Ly-$\alpha$ emission at the same redshift, with a centroid located at a most probable impact parameter of only $\rho\,\simeq$ 1.4 kpc. We argue that the line of sight is therefore likely passing through the ISM of a galaxy as opposed to the CGM. The relation between the surface density of gas and that of star formation seems to follow the global empirical relation derived in the nearby Universe although our constraints on the star formation rate and on the galaxy extent remain too loose to be conclusive. We study the transition from atomic to molecular hydrogen using a theoretical description based on the microphysics of molecular hydrogen. We use the derived chemical properties of the cloud and physical conditions (T$_k\,\simeq$90 K and n$\simeq$250 cm$^{-3}$ derived through the excitation of H$_2$ rotational levels and neutral carbon fine structure transitions to constrain the fundamental parameters that govern this transition. By comparing the theoretical and observed HI column densities, we are able to bring an independent constraint on the incident UV flux, which we find to be in agreement with that estimated from the observed star formation rate., Comment: accepted for publication in A&A

Astrophysics - Astrophysics of Galaxies - Abstract
With a total integration time of 168 hours and a narrowband (NB) filter tuned to Lyman alpha at z = 8.8, the UltraVISTA survey has set out to find some of the most distant galaxies, on the verge of the Epoch of Reionization. Previous calculations of the expected number of detected Lya-emitting galaxies (LAEs) at this redshift did not explicitly take into account the radiative transfer (RT) of Lya. In this work we combine a theoretical model for the halo mass function with numerical results from high-res cosmological hydrosimulations with LyC+Lya RT, assessing the visibility of LAEs residing in these halos. Uncertainties such as cosmic variance and the anisotropic escape of Lya are taken into account, and it is predicted that once the survey has finished, the probabilities of detecting none, one, or more than one are ~90%, ~10%, and ~1%; a significantly smaller success rate compared to earlier predictions, due to the combined effect of a highly neutral IGM scattering Lya to such large distances from the galaxy that they fall outside the observational aperture, and to the actual depth of the survey being less than predicted. Because the IGM affects NB and broadband (BB) magnitudes differently, we argue for a relaxed color selection criterion of NB - BB ~ +0.85. But since the flux is continuum-dominated, even if a galaxy is detectable in the NB its probability of being selected as a NB excess object is <~35%. Various properties of galaxies at this redshift are predicted, e.g. UV and Lya LFs, M*-Mh relation, spectral shape, optimal aperture, and the anisotropic escape of Lya through both a dusty ISM and a partly neutral IGM. Finally, we describe and publish a fast numerical code for adding numbers with asymmetric uncertainties ("x_{-sigma_1}^{+sigma_2}") proving to be significantly better than the standard, but wrong, way of adding upper and lower uncertainties in quadrature separately., Comment: Submitted to A&A, comments are welcome

Computer Science - Robotics - Abstract
Mapping field environments into point clouds using a 3D LIDAR has the ability to become a new approach for online estimation of crop biomass in the field. The estimation of crop biomass in agriculture is expected to be closely correlated to canopy heights. The work presented in this paper contributes to the mapping and textual analysis of agricultural fields. Crop and environmental state information can be used to tailor treatments to the specific site. This paper presents the current results with our ground vehicle LiDAR mapping systems for broad acre crop fields. The proposed vehicle system and method facilitates LiDAR recordings in an experimental winter wheat field. LiDAR data are combined with data from Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU) sensors to conduct environment mapping for point clouds. The sensory data from the vehicle are recorded, mapped, and analyzed using the functionalities of the Robot Operating System (ROS) and the Point Cloud Library (PCL). In this experiment winter wheat (Triticum aestivum L.) in field plots, was mapped using 3D point clouds with a point density on the centimeter level. The purpose of the experiment was to create 3D LiDAR point-clouds of the field plots enabling canopy volume and textural analysis to discriminate different crop treatments. Estimated crop volumes ranging from 3500-6200 (m3) per hectare are correlated to the manually collected samples of cut biomass extracted from the experimental field., Comment: 9 pages, 6 figures, conference (ICPA 2018)

- Abstract
Cancer of unknown primary (CUP) tumors are biologically very heterogeneous, which complicates stratification of patients for treatment. Consequently, these patients face limited treatment options and a poor prognosis. With this study, we aim to expand on the current knowledge of CUP biology by analyzing two cohorts: a well‐characterized cohort of 44 CUP patients, and 213 metastatic patients with known primary. These cohorts were treated at the same institution and characterized by identical molecular assessments. Through comparative analysis of genomic and transcriptomic data, we found that CUP tumors were characterized by high expression of immune‐related genes and pathways compared to other metastatic tumors. Moreover, CUP tumors uniformly demonstrated high levels of tumor‐infiltrating leukocytes and circulating T cells, indicating a strong immune response. Finally, the genetic landscape of CUP tumors resembled that of other metastatic cancers and demonstrated mutations in established cancer genes. In conclusion, CUP tumors possess a distinct immunophenotype that distinguishes them from other metastatic cancers. These results may suggest an immune response in CUP that facilitates metastatic tumor growth while limiting growth of the primary tumor. [ABSTRACT FROM AUTHOR]

- Abstract
The present study compares two methods for assessing peer influence: the longitudinal actor-partner interdependence model (L-APIM) and the longitudinal social network analysis (L-SNA) Model. The data were drawn from 1,995 (49% girls and 51% boys) third grade students (M[subscript age] = 9.68 years). From this sample, L-APIM (n = 206 indistinguishable dyads and n = 187 distinguishable dyads) and L-SNA (n = 1,024 total network members) subsamples were created. Students completed peer nominations and objective assessments of mathematical reasoning in the spring of the third and fourth grades. Patterns of statistical significance differed across analyses. Stable distinguishable and indistinguishable L-APIM dyadic analyses identified reciprocated friend influence such that friends with similar levels of mathematical reasoning influenced one another and friends with higher math reasoning influenced friends with lower math reasoning. L-SNA models with an influence parameter (i.e., average reciprocated alter) comparable to that assessed in L-APIM analyses failed to detect influence effects. Influence effects did emerge, however, with the addition of another, different social network influence parameter (i.e., average alter influence effect). The diverging results may be attributed to differences in the sensitivity of the analyses, their ability to account for structural confounds with selection and influence, the samples included in the analyses, and the relative strength of influence in reciprocated best as opposed to other friendships.

Computer Science - Robotics - Abstract
This paper describes a collaborative modelling approach to automated and robotic agricultural vehicle design. The Cresendo technology allows engineers from different disciplines to collaborate and produce system models. The combined models are called co-models and their execution co-simulation. To support future development efforts a template library of different vehicle and controllers types are provided. This paper describes a methodology to developing co-models from initial problem definition to deployment of the actual system. We illustrate the development methodology with an example development case from the agricultural domain. The case relates to an encountered speed controller problem on a differential driven vehicle, where we iterate through different candidate solutions and end up with an adaptive controller solution based on a combination of classical control and learning feedforward. The second case is an example of combining human control interface and co-simulation of agricultural robotic operation to illustrate collaborative development

Physics - Chemical Physics - Abstract
Time-resolved X-ray scattering patterns from photoexcited molecules in solution are in many cases anisotropic at the ultrafast time scales accessible at X-ray Free Electron Lasers (XFELs). This anisotropy arises from the interaction of a linearly polarized UV-vis pump laser pulse with the sample, which induces anisotropic structural changes that can be captured by femtosecond X-ray pulses. In this work we describe a method for quantitative analysis of the anisotropic scattering signal arising from an ensemble of molecules and we demonstrate how its use can enhance the structural sensitivity of the time-resolved X-ray scattering experiment. We apply this method on time-resolved X-ray scattering patterns measured upon photoexcitation of a solvated di-platinum complex at an XFEL and explore the key parameters involved. We show that a combined analysis of the anisotropic and isotropic difference scattering signals in this experiment allows a more precise determination of the main photoinduced structural change in the solute, i.e. the change in Pt-Pt bond length, and yields more information on the excitation channels than the analysis of the isotropic scattering only. Finally, we discuss how the anisotropic transient response of the solvent can enable the determination of key experimental parameters such as the Instrument Response Function., Comment: Accepted for publication in Journal of Synchrotron Radiation

Astrophysics - Astrophysics of Galaxies - Abstract
We examine the dust geometry and Ly{\alpha} scattering in the galaxies of the Lyman Alpha Reference Sample (LARS), a set of 14 nearby (0.02 < $z$ < 0.2) Ly{\alpha} emitting and starbursting systems with Hubble Space Telescope Ly{\alpha}, H{\alpha}, and H{\beta} imaging. We find that the global dust properties determined by line ratios are consistent with other studies, with some of the LARS galaxies exhibiting clumpy dust media while others of them show significantly lower Ly{\alpha} emission compared to their Balmer decrement. With the LARS imaging, we present Ly{\alpha}/H{\alpha} and H{\alpha}/H{\beta} maps with spatial resolutions as low as $\sim$ 40 pc, and use these data to show that in most galaxies, the dust geometry is best modeled by three distinct regions: a central core where dust acts as a screen, an annulus where dust is distributed in clumps, and an outer envelope where Ly{\alpha} photons only scatter. We show that the dust that affects the escape of Ly{\alpha} is more restricted to the galaxies' central regions, while the larger Ly{\alpha} halos are generated by scattering at large radii. We present an empirical modeling technique to quantify how much Ly{\alpha} scatters in the halo, and find that this "characteristic" scattering distance correlates with the measured size of the Ly{\alpha} halo. We note that there exists a slight anti-correlation between the scattering distance of Ly{\alpha} and global dust properties., Comment: 32 pages, 51 figures, accepted to ApJ

- Abstract
• Patients' body and mind are onslaught by chronic limb-threatening ischemia (CLTI). • Patients with CLTI transition from independency to dependency. • Patients' capacity to be involved in decision-making decreased as CLTI advanced. • Person-centered care is vital to embrace patient experienced attack on body and mind. Patients facing chronic limb-threatening ischemia (CLTI) experience significant burdens, impacting their physical, emotional, and social well-being. They require extensive care from multidisciplinary healthcare professionals across primary and secondary settings. Managing CLTI necessitates strict patient adherence to treatment protocols to prevent severe complications. Surprisingly, previous studies have overlooked these patients' unique perspectives, highlighting the need to explore their experiences and challenges. The objective of this review was to systematically identify, examine, and conceptually map extant literature on patients with CLTI in the context of living with the condition, and explore their experiences of receiving treatment and care within a cross-sectoral setting. A systematic search was completed on 18 September 2023 with no methodological or format restrictions. We identified the population, concept, and context to pinpoint the delineate the focus of this review process. The JBI methodology for scoping reviews and the PRISMA-ScR checklist were followed. Based on our search, we found ten relevant scientific qualitative and/or quantitative sources and one non-scientific source. We identified four main maps: 1) Dependency on others is my new life condition, 2) I'm more than the sum of my conditions , 3) I'm lost in chaos, be alert to all of me , and 4) Give me more time, my body and mind are under attack. This scoping review describes how patients' lives are affected by CLTI and provides insights into their perception of shared decision-making, treatment, and care. The review reveals the need for a more person-centered approach to care. To nuance person-centred care further, it is necessary to consider the impact of patients' cultural values and preferences. However, this area is marked by a notable research gap. [Display omitted] [ABSTRACT FROM AUTHOR]

- Abstract
Strong evidence indicates that student expectations of success in mathematics decline in middle school. The goal of the present study was to examine whether the expectations of teachers and the quality of the student-teacher relationship play a role in these declines. A total of 201 (86 boys, 115 girls) Latino/a students (M = 11.0 years) and their teachers completed surveys at the beginning and end of the 6th grade, describing expectations of the student's success in mathematics and perceptions of teacher involvement with the student. Higher teacher expectations of mathematics success and higher student reports of teacher involvement anticipated greater increases in student expectations of success; the former (but not the latter), was limited to students with above average mathematics abilities.

150. Building Gender Equity in the Academy: Institutional Strategies for Change

Laursen, Sandra, Austin, Ann E., Laursen, Sandra, and Austin, Ann E.
- Abstract
Despite decades of effort by federal science funders to increase the numbers of women holding advanced degrees and faculty jobs in science and engineering, they are persistently underrepresented in academic STEM disciplines, especially in positions of seniority, leadership, and prestige. Women filled 47% of all US jobs in 2015, but held only 24% of STEM jobs. Barriers to women are built into academic workplaces: biased selection and promotion systems, inadequate structures to support those with family and personal responsibilities, and old-boy networks that can exclude even very successful women from advancing into top leadership roles. But this situation can--and must--change. In "Building Gender Equity in the Academy," Sandra Laursen and Ann E. Austin offer a concrete, data-driven approach to creating institutions that foster gender equity. Focusing on STEM fields, where gender equity is most lacking, Laursen and Austin begin by outlining the need for a systemic approach to gender equity. Looking at the successful work being done by specific colleges and universities around the country, they analyze twelve strategies these institutions have used to create more inclusive working environments, including: (1) implementing inclusive recruitment and hiring practices; (2) addressing biased evaluation methods; (3) establishing equitable tenure and promotion processes; (4) strengthening accountability structures, particularly among senior leadership; (5) improving unwelcoming department climates and cultures; (6) supporting dual-career couples; (7) offering flexible work arrangements that accommodate personal lives; and (8) promoting faculty professional development and advancement. Laursen and Austin also discuss how to bring these strategies together to create systemic change initiatives appropriate for specific institutional contexts. Drawing on three illustrative case studies--at Case Western Reserve University, the University of Texas at El Paso, and the University of Wisconsin-Madison--they explain how real institutions can strategically combine several equity-driven approaches, thereby leveraging their individual strengths to make change efforts comprehensive. Grounded in scholarship but written for busy institutional leaders, Building Gender Equity in the Academy is a handbook of actionable strategies for faculty and administrators working to improve the inclusion and visibility of women and others who are marginalized in the sciences and in academe more broadly.
