No studies have reported on the impact at team level of the Medtronic Hugo™ RAS system. We described the work patterns and learning curves of an experienced robotic nurse team adapting to the new robotic system. We prospectively recorded the robotic nurse team’s preoperative, perioperative, and postoperative tasks on the first 30 robotic procedures performed. The data were descriptively analyzed, and Gantt Charts were created for a timeline overview of the work patterns. We compared the operative times between the Medtronic Hugo™ RAS and the Davinci® system. The preoperative phase seemed to improve with a median time of 94 min (IQR 81–107). After 20 surgeries, the work pattern became more consistent where the scrub and circulating nurses worked simultaneously. There was no noticeable improvement for the perioperative and postoperative phases with a stable median time of 170 min (IQR 135–189) and 26 min (IQR 22–31). We found that the work pattern seemed to stabilize after 20 surgeries but with a continued decrease in preoperative time without a learning curve plateau. The robotic nurse team suffered from few breaks and long working hours because only a few nurses at our facility were trained in the Hugo™ system. [ABSTRACT FROM AUTHOR]

To assess the association of regional socioeconomic deprivation and nicotine use, survey data from 17,877 pupils aged 9–17 years were analysed. Lifetime use of combustible, e-cigarettes, and both products were the outcome variables. The German Index of Socioeconomic Deprivation was the exposure variable. Logistic regression models controlling for age, gender, school type, and sensation seeking were used to examine associations between regional socioeconomic deprivation and nicotine use. Ever use of combustible cigarettes was 17.8%, of e-cigarettes 19.6%, and of both products 13.4%. Compared to the most affluent area, the adjusted odds ratio of combustible cigarette use in the most deprived area was 2.24 (95% CI: 1.67–3.00), of e-cigarette use 1.56 (95% CI: 1.20–2.03), and of poly use 1.91 (95% CI: 1.36–2.69). Nicotine use among young people across ages and especially in socioeconomic-deprived areas was widespread. Nicotine control measures are urgently needed to reduce smoking and vaping in German adolescents. [ABSTRACT FROM AUTHOR]

Purpose: Recently, the robotic surgical system, Hugo™ was approved for clinical use. The transfer of skills is important for understanding the implementation of surgical innovation. We explored the transfer of skills from the DaVinci® to the Hugo™ by studying the learning curve and short-term patient outcomes during radical prostatectomy (RARP). Methods: We examined the transfer of skills from one surgeon performing RARP from the first case with the Hugo™ system in April 2022. The surgeon had previously performed > 1000 RARPs using DaVinci®. Perioperative and clinical outcomes were collected for procedures on both Hugo™ and DaVinci®. Patient follow-up time was 3 months. Results: Nineteen Hugo™ cases and 11 DaVinci® cases were recorded. No clinically relevant difference in procedure time was found when transferring to Hugo™. Patients operated using Hugo™ had more contacts postoperatively compared to the DaVinci®, all Clavien–Dindo (CD) grade 1 (53% vs 18%). Three patients from the Hugo™ group were re-admitted within 30 days with catheter malfunction (CD grade 1), infection without a focus (CD grade 2), and ileus due to a hernia in the port hole (CD grade 3b). The 3-month follow-up showed similar results in prostate-specific antigen levels (PSA) and erectile dysfunction between the two robotic systems, but a higher incidence of incontinence was found for the Hugo™. Conclusion: We observed that the skills of an experienced robotic surgeon are transferable from DaVinci® to Hugo™ when performing RARP. No obvious benefits were found for using Hugo™ compared to DaVinci® for RARP although this needs confirmatory studies. [ABSTRACT FROM AUTHOR]

Purpose: Accurate surgical reconstruction of arterial vascular supply is a crucial part of living kidney transplantation (LDKT). The presence of multiple renal arteries (MRA) in grafts can be challenging. In the present study, we investigated the impact of ligation versus anastomosis of small accessory graft arteries on the perioperative outcome. Methods: Clinical and radiological outcomes of 51 patients with MRA out of a total of 308 patients who underwent LDKT with MRA between 2011 and 2020 were stratified in two groups and analyzed. In group 1 (20 patients), ligation of accessory arteries (ARAs) and group 2 (31 patients) anastomosis of ARAs was performed. Results: Significant differences were observed in the anastomosis-, surgery-, and warm ischemia time (WIT) in favor of group 1. Students t-test showed comparable serum creatinine levels of 2.33 (± 1.75) to 1.68 (± 0.83) mg/dL in group 1 and 2.63 (± 2.47) to 1.50 (± 0.41) mg/dL in group 2, were seen from 1 week to 1 year after transplant. No increased rates of Delayed graft function (DGF), primary transplant dysfunction and transplant rejection were seen, but graft loss and revision rates were slightly higher when the ARAs were ligated. Analysis of Doppler sonography revealed that segmental perfusion deficits tend to regenerate during the clinical course. Conclusion: Ligation of smaller accessory renal arteries may not affect the outcome of living kidney transplantation, except for a minor increase in the reoperation rate. Segmental perfusion deficits of the graft seem to regenerate in most cases as seen in Doppler sonography. [ABSTRACT FROM AUTHOR]

Diffuse large B cell lymphoma (DLBCL) is a genetically highly heterogeneous disease. Yet, to date, the vast majority of patients receive standardized frontline chemo-immune-therapy consisting of an anthracycline backbone. Using these regimens, approximately 65% of patients can be cured, whereas the remaining 35% of patients will face relapsed or refractory disease, which, even in the era of CAR-T cells, is difficult to treat. To systematically tackle this high medical need, it is important to design, generate and deploy suitable in vivo model systems that capture disease biology, heterogeneity and drug response. Recently published, large comprehensive genomic characterization studies, which defined molecular sub-groups of DLBCL, provide an ideal framework for the generation of autochthonous mouse models, as well as an ideal benchmark for cell line-derived or patient-derived mouse models of DLBCL. Here we discuss the current state of the art in the field of mouse modelling of human DLBCL, with a particular focus on disease biology and genetically defined molecular vulnerabilities, as well as potential targeting strategies.

To examine the relationship between regional socioeconomic deprivation and adherence to the 24-h movement guidelines among children and adolescents, a cross-sectional study was conducted. A total of 17,433 students aged 9–17 participated in a survey in winter 2021/2022. Daily screen time (ST), moderate-to-vigorous physical activity (MVPA), and sleep behavior were outcome variables. The German Index of Socioeconomic Deprivation (GISD), a regional socioeconomic objective measure, was the exposure variable. Associations between GISD and health behaviors were examined using regression models. Models were adjusted for age, gender, school type, and individual self-reported socioeconomic status (SES). The proportions of meeting the MVPA, ST, and sleep duration guidelines were 14%, 22%, and 34%, respectively. A total of 2.3% met all guidelines. Students from the most deprived communities were half as likely to meet all three guidelines compared to students from the most affluent regions (OR = 0.49 [0.28; −0.03], p = 0.010). There was a consistent relationship between GISD and lower levels of adherence to screen time guidelines (most deprived compared to most affluent: OR = 0.49 [0.38; 0.64], p < 0.001). There was no association between GISD and adherence to sleep time guidelines. We found mixed results for the association between GISD and MVPA. Regional SES appears to be an important factor associated with screen time. Screen time should be limited through intervention programs, especially in disadvantaged areas. Parents should be made aware of their children's increased media consumption. Recommendations for screen time should be clearly communicated, as should the health disadvantages of increased media consumption in childhood and adolescence. [ABSTRACT FROM AUTHOR]

The objective was to examine pandemic-related changes in depression and anxiety symptoms in adolescents and young adults in Germany considering pre-existing depression and anxiety problems. In this cross-sectional study, 11,523 adolescents and young adults aged 14–21 years who perceived an impact of the Coronavirus disease (COVID-19) pandemic on their mental health reported the frequencies of depression and anxiety symptoms retrospectively for different pre-pandemic and pandemic phases. Data were collected using web-based questionnaires between January 5th and February 20th, 2022. Depression and anxiety were assessed with a modified version of the Patient Health Questionnaire (PHQ-4). Scale-fit cut-offs were used to identify pre-existing elevated depression and anxiety scores. Multilevel mixed linear models were conducted to assess changes in depression and anxiety symptoms from 2019 to 2021 and compare for age, gender and pre-pandemic mental health problems. Among young people who were experiencing mental health changes as a result of the pandemic, the frequency of depression and anxiety symptoms increased during the COVID-19 pandemic. This association was moderated by age, gender, and pre-existing elevated depression/anxiety scores. For young people without elevated pre-pandemic depression/anxiety, the scores increased strongly over time, with 61% reporting elevated depression symptoms and 44% reporting elevated anxiety symptoms in 2021. In contrast, self-perceived change was minimal for adolescents and young adults with elevated pre-pandemic depression and anxiety. Among young people whose mental health has been affected by the COVID-19 pandemic, the group without pre-pandemic mental health conditions reported greater deterioration than those with elevated pre-pandemic depression and anxiety scores. Thus, adolescents and young adults without pre-existing depression and anxiety problems who perceived a change in general mental health due to the pandemic reported an alarming increase in symptoms of depression and anxiety during the COVID-19 pandemic period.

Background: Pulmonary Tuberculosis (TB) is diagnosed through sputum samples. As sputum sampling is challenging in children and cachexic patients, the development of diagnostic tests using saliva appears promising but has been discouraged due to low bacterial load and poor sensitivity. Here, we present a novel and rapid method to enrich Mycobacterium tuberculosis (Mtb) from saliva, which may serve as a basis for a diagnostic saliva test. Methods: Lipobiotin-functionalized magnetic beads (LMBs) were incubated with Mtb-spiked PBS and saliva from healthy donors as well as with saliva from TB patients. Flow cytometry was used to evaluate the capacity of the beads to bind Mtb, while real-time quantitative polymerase chain reaction (qPCR) was utilized to detect Mtb and determine the amount of mycobacterial DNA in different sample types. Results: We found that LMBs bind Mtb efficiently when compared to non-functionalized beads. The development of an qPCR assay based on the use of LMBs (LMB assay) allowed us to enrich mycobacterial DNA in spiked sample types, including PBS and saliva from healthy donors (enrichment of up to ~8.7 fold). In Mtb-spiked saliva samples, we found that the LMB assay improved the detection rate of 102 bacteria in a volume of 5 ml from 0 out of 15 (0%) to 6 out of 15 (40%). Consistent with that, the LMB assay increased the rate of correctly identified saliva samples from TB patients in two independent cohorts. Conclusions: Implementation of the principle of the LMB-based assay may improve the sensitivity of existing diagnostic techniques, e.g. by functionalizing materials that facilitate Mtb sampling from the oral cavity.

The interactions between physical activity (PA), screen time, and sleep affect the health of children and adolescents. This study described the national prevalence estimates of German youth aged 9 to 18 years who meet PA, screen time, and sleep guidelines alone and in combination and examined the associations of demographic and personal characteristics with adherence to guidelines. Data from a 2019–2020 German student survey were used (n = 15,786). The target population consisted of children and adolescents enrolled in grades 5–10, with a mean age of 13.0 years (SD = 1.8) and an equal gender distribution (male: 50%). The levels of PA, screen time, and sleep were assessed by self-reports (online questionnaires). The prevalence rates of meeting each guideline individually and in different combinations were calculated, and multilevel logistic regression models were used to examine the associations of demographic and personal characteristics with meeting versus not meeting guidelines. Overall, 9.7% of the respondents met all three guidelines combined, and approximately 25% did not meet any of the guidelines. Half of the participants (50%) met the sleep guidelines, and approximately one third met the screen time (35%) and PA (37%) guidelines alone. Demographic characteristics associated with adherence to meeting all three movement guidelines included younger age, male gender, higher self-reported socioeconomic status, and school type. Personal characteristics related to adherence to meeting all three movement guidelines included better subjective school performance, less frequent attention deficit hyperactivity disorder (ADHD), lower levels of depressive symptoms, lower body mass index (BMI), and not using substances in the past 30 days. Conclusion: A low percentage of German children and adolescents met the movement guidelines. With increasing age, the proportion of young people who follow the recommendations decreases. There is an urgent need for health interventions devoted to youth behavior as a whole. What is Known: • High levels of PA, low levels of screen time, and optimal sleep duration provide enhanced health benefits in comparison to the adoption of just one of these behaviors. • Evidence shows that movement behaviors interact throughout the day and should be studied concurrently. What is New: • Approximately 10% of German children and adolescents met the recommendations on PA, screen time, and sleep, while 25% did not meet any guidelines. • Meeting all guidelines was associated with less frequent ADHD and depressive symptoms, lower BMI, and less frequent substance use in the past 30 days.

The growing use of simulation-based training makes it necessary to develop efficient training programs in order to ensure optimal use of time and resources. Our aim was to develop and gather validity evidence for a simulation-based test in ureteronephroscopy and set a pass/fail standard for the test that will allow future mastery learning. This study is a validation study. A test in ureteronephroscopy and stone removal on the URO Mentor™ virtual reality simulator (3D Systems, USA) was developed by two experienced urologists in order to ensure content. Participants with different experience completed three standardized tasks on the simulator and simulator-generated metrics were used as outcome parameters to minimize bias and ensure a fair response process. Twenty novices, 15 intermediates, and 8 experienced urologists were included in the study. Validity evidence for internal structure and relationship to other variables was questionable with weak and mostly insignificant correlations across all four metrics (Cronbach's alpha = 0.14, p = 0.15) and across the three modules (Cronbach's alpha = 0.41 (p = 0.02), 0.35 (p = 0.06), 0.10 (p = 0.35), and 0.30 (p = 0.09) for each metric, respectively). It was not possible to establish a pass/fail score for the simulation test with meaningful consequences. Our study showed that automatically generated simulator metrics cannot be used as a valid way of assessing competence in ureteronephroscopy. Virtual-reality simulator training could still be a valuable and patient-safe way to practice these skills, but an experienced supervisor is needed to determine when the trainee is ready to continue to supervised practice on patients.

This study examined the association between bullying victimization and e‐cigarette use. Data from a 2019–2020 German student survey were used (N = 16,476). The target population consisted of students enrolled in grades 5–10, with a mean age of 13.1 years (SD = 1.8), and equal gender distribution (49.5% female). Mixed‐effect multivariable logistic regression models were used to examine the association between bullying victimization (attacked physically, assaulted verbally, experienced relational bullying, sexual harassment, cyberbullying) and current e‐cigarette use. The multivariable analysis controlled for age, sex, sensation‐seeking, socioeconomic status, school performance, type of school attended, and substance use (current cigarette smoking, hookah smoking, and alcohol drinking). Overall 510 (3.7%) students reported current use of e‐cigarettes. The odds for using e‐cigarettes increased each step of being bullied from "never," "rarely," "sometimes," "once a week," to "several times a week" by 2.03 (95% confidence interval [CI]: 1.81, 2.29) in the unadjusted model, and by 1.46 (95% CI: 1.24, 1.71) in the covariate‐adjusted model. Data indicate an empirical association between victimization and e‐cigarette use among German students. Design limitations prevent the conclusion of a causal relationship, calling for well‐designed longitudinal studies to investigate the temporal sequence between victimization and e‐cigarette use.

Background: Aggressive marketing has resulted in exponential growth of energy drink sales in recent years. Despite growing concerns about the negative health effects of energy drinks, they are increasingly popular among young people. Little is known about temporal associations between energy drink consumption and other drug use, though some researchers have suggested that energy drink consumption reflects an entry into a drug-using lifestyle.Aims: The purpose of this study was to evaluate whether energy drink use among adolescents who have never tried substances is associated with a risk of initiating tobacco (i.e. cigarettes, e-cigarettes, and hookah) and alcohol use.Methods: A school-based longitudinal study of 3071 adolescents ages 9-17 years was conducted in six federal states of Germany. Data analyses involved two assessment waves that took place approximately 12 months apart: baseline (fall-winter of school year 2016-2017), and 12-month follow-up (fall-winter of school year 2017-2018).Results: Multilevel models revealed that energy drink use at baseline was associated with cigarette (odds ratio for energy drink ever use, 3.15 (95% confidence interval, 2.07-4.78 )), e-cigarette (odds ratio, 4.32 (95% confidence interval, 2.87-6.51)), hookah smoking (odds ratio, 3.15 (95% confidence interval, 2.06-4.82)), and alcohol use (odds ratio, 2.26 (95% confidence interval, 1.75-2.93)) initiation within 12 months.Conclusions: These results raise the possibility that energy drinks may potentially act as a gateway drug to other substances. However, inferences regarding whether this association is or is not causal cannot yet be made. [ABSTRACT FROM AUTHOR]

Der Präventionsradar untersucht das gesundheitsrelevante Verhalten von Kindern und Jugendlichen in Deutschland und wird seit 2016 einmal jährlich an Schulen durchgeführt. Durch die Kombination aus Quer- und Längsschnittstudie ermöglicht der Präventionsradar neben der Analyse des aktuellen Gesundheitsverhaltens auch die Betrachtung dieser Verhaltensweisen im Zeitverlauf. Des Weiteren werden durch den Präventionsradar Schulen in ihrer Präventionsarbeit unterstützt. The "Präventionsradar" examines child and youth health in Germany and has been carried out in schools once a year since 2016. Combining a cross-sectional and longitudinal design, the study allows for analyzing both current health behaviors as well as the development of these behaviors over time. Moreover, the "Präventionsradar" provides valuable support for school-based prevention programs. [ABSTRACT FROM AUTHOR]

ABSTRACT: BACKGROUND: Physical activity (PA) is one of the most important health behaviors that may be modified by each individual. To foster PA in adolescents, a school‐based intervention was evaluated. METHODS: A cluster‐randomized controlled trial with preassessment in 2014 and follow‐up assessment in 2015 included 29 schools with 1020 students (47.6% girls, mean age = 13.69 years). Intervention students received pedometers and monitored their steps for 12 weeks. Classes with the most steps were awarded. Primary outcomes included moderate‐to‐vigorous PA, out‐of‐school sports activities, active transport assessed through questionnaires, as well as cardiorespiratory fitness measured using the 20‐m shuttle‐run test and anthropometric data (weight, height, body fat, and waist circumference) assessed by study staff. RESULTS: Significant interaction terms between group and time were found for all 3 indicators of PA; intervention students showed a higher increase of PA than control students. The same pattern was shown for cardiorespiratory fitness, but the effect missed significance. A more favorable development for the intervention students was shown for body fat and waist‐to‐height ratio, while there was no effect on body mass index percentile. CONCLUSIONS: An easy way to administer school‐based PA program may enhance students' leisure‐time PA even 1 year after the intervention has ended. [ABSTRACT FROM AUTHOR]

The essay looks at the confusions between real and imaginary places as revealed by Thomas Campbell's poem "Gertrude of Wyoming" and attempts to reconstruct 19th-century ideals and ideologies of heroine reading disseminated through the poem. It examines Campbell's naturalistic errors and the differential ethical stakes for different kinds of errors as it relates to the geographical inaccuracies in the poem and its vividness.

Risk is always present in people's lives: diseases, new technologies, socio-scientific issues (SSIs) such as climate change, and advances in medicine-to name just a few examples-all carry risks. To be able to navigate risks in everyday life, as well as to participate in social debate on risk-related issues, students need to develop risk competence. Science education can be a powerful tool in supporting students' risk competence, which is an important component of scientific literacy. As there are different definitions of risk within the scientific community, the aims of this article are (1) to review the literature on two major theoretical frameworks for conceptualising risk, the realist, and the constructivist paradigms of risk and (2) to connect both in order to suggest a working definition of what can be understood as risk competence in science instruction.

The risk of death is increased for persons with epilepsy. The literature on causes of death in epilepsy is based mainly on cohorts with epilepsy of mixed aetiologies. For clinical purposes and improved understanding of mortality in different epilepsies, more information is needed on mortality in epilepsies of specific causes. In poststroke epilepsy (PSE), seizures occur in a setting of vascular disease and high mortality rates. The extent to which epilepsy contributes to mortality in this patient group is poorly understood. We therefore aimed to describe causes of death (COD) in PSE on a national scale. A previously identified cohort of 7740 patients with epilepsy or seizures after a stroke in 2005–2010 was investigated. A total of 4167 deaths occurred before the end of 2014. The standardized mortality ratio for the study cohort was 3.56 (95% CI: 3.45–3.67). The main underlying causes of death were disorders of the circulatory system (60%) followed by neoplasms (12%). Diseases of the nervous system were the sixth leading underlying COD (3%), and epilepsy or status epilepticus was considered the underlying COD in approximately a similar proportion of cases as neurodegenerative disorders (0.9% and 1.1%, respectively). Epilepsy was considered a contributing COD in 14% of cases. Our findings highlight the importance of optimal management of vascular morbidity in patients with PSE. The large proportion of patients with epilepsy as a contributing COD indicate the need of high ambitions also regarding the management of seizures in patients with PSE. [ABSTRACT FROM AUTHOR]

"Eigenständig werden 5+6" (Becoming independent 5+6) is a German school-based smoking prevention program that draws on social competence and social influence approaches. It was investigated whether the program's effect on smoking onset is mediated by substance-specific skills and cognitions such as knowledge, attitudes/risk perception, normative expectations, resistance skills, and refusal self-efficacy. Multiple mediation analyses revealed a statistically significant total indirect effect that accounted for 30.8% of the total effect. When considered separately, significant indirect effects could be found for normative expectations concerning peer smoking and the resistance skill of saying 'no'. Between these two mediators, the percentage of total effect mediated varied between 9.8% and 10.3%. Results of the current study emphasize the importance of substance-specific skills and cognitions in the effectiveness of school-based programs combining social competence and social influence curricula in preventing adolescent smoking onset.

Objectives: To test the effects of a school-based prevention programme on students' smoking-related behaviour, attitudes and knowledge 6 months after implementation over 2 school-years has ended. Design: Two-arm prospective cluster randomised controlled trial with a follow-up survey 6 months after end of programme implementation, that is, 26 months after baseline. Setting: 45 public secondary schools from four federal states in Germany (Bremen, Hesse, North Rhine-Westphalia, Schleswig-Holstein). Participants: A total of 3444 students from 172 classes with a mean age of 10.37 years (SD=0.59) and 47.9% girls at baseline. Analysis sample with follow-up up data merged to baseline data comprises 2513 datasets (73%). Intervention: 'Eigenständig werden 5+6', a school-based prevention programme for grades 5 and 6 to enhance substance-specific and general life skills, consisting of 14 units (à 90 min) and two workshops (4--6 h) being taught over a time period of 2 school-years by trained teachers. Outcome measures: Lifetime and current smoking, incidence of smoking in baseline never smokers, smoking-related knowledge, attitudes, perceived norms of smoking and self-efficacy to refuse cigarette offers were assessed in students. Results: 6 months after the end of programme implementation, students of intervention classes showed significantly lower rates for lifetime smoking (adjusted OR=0.63; 95% CI 0.41 to 0.96; p=0.026) and incidence of smoking (adjusted OR=0.66; 95% CI 0.43 to 1.00; p=0.047), a higher increase of smoking-related knowledge (adjusted β=9.38; 95% CI 6.73 to 12.04; p<0.001) and a greater change in attitudes towards a more critical perception of risks and disadvantages of smoking (adjusted β=0.10; 95% CI 0.03 to 0.16; p=0.002). No group differences were found for current smoking, perceived norms of smoking and self-efficacy to refuse cigarette offers. Conclusions: Participation in the school-based prevention programme 'Eigenständig werden 5+6' may have small effects on smoking behaviour and attitudes and a moderate effect on smoking-related knowledge.

Given a relatively inelastic supply of locations with coastal water views, the price of a water view is likely to rise during housing market upturns and fall during downturns. Using 25 years of data and more than 20,000 home sales for Bellingham, Washington, this study uses the hedonic methodology to estimate water view premiums over different phases of the housing cycle. Views are differentiated both by scope and by distance from the water. Results show real dollar premiums associated with water views move with the housing cycle, rising when housing demand and overall market prices increase and falling when the overall price of housing declines. In addition, the relative value of a view fluctuates as well. [ABSTRACT FROM AUTHOR]

Background Physical activity during childhood and adolescence is associated with substantial health benefits and tracks into adulthood. Nevertheless, only 22.7% of German adolescents are sufficiently physically active. Thus, the promotion of an active lifestyle in youth is an essential issue of public health. This study will evaluate the implementation and efficacy of the "läuft." program to enhance physical activity in adolescence. "läuft." is a multicomponent school-based program developed on the basis of effective strategies for health interventions and behavioral change. Methods/design The "läuft." physical activity program targets four different levels. (a) Each student receives a pedometer and documents his/her steps over 12 weeks using an interactive user account on the "läuft." homepage. (b) For classes there will be different competitions, with achieving the most steps in selected weeks, the highest increases of steps and developing the most inventive ideas to promote physical activity in school. Besides, the intervention includes four educational lessons. (c) The headmasters and teaching staff of the participating schools will get information material with suggestions and encouragement to enhance physical activity in school. Participating teachers will be invited to an introductory seminar. (d) Parents will be provided with informational material about the program and will be invited to a parentteacher conference about the benefits of being physically active and how they can support their children in engaging in a physically active lifestyle. To evaluate the efficacy of the "läuft." physical activity program, a two-arm cluster randomized controlled trial will be conducted in three waves: (1) baseline assessment, January/February 2014, (2) post assessment, June/July 2014 and (3) 12-month follow-up assessment, June/July 2015. Data collection will include physical and medical testing, selfadministered questionnaires, group discussions and document analyses. Discussion "läuft." aims at fostering a physically active lifestyle in adolescence while a considerable decline of physical activity is present. Physical activity programs based in the school setting and following a multicomponent approach have been proven to be most successful. Furthermore, the use of pedometers is promising to enhance physical activity during the entire day and targets a wide range of adolescents regarding fitness and weight [ABSTRACT FROM AUTHOR]

Objective: To implement and evaluate 'Eigenständig werden 5+6' ('Becoming Independent 5+6'), a school-based curriculum for grades 5 and 6 developed on the basis of evidence-based criteria for effective drug prevention curricula in schools. Evaluation of the programme includes efficacy, feasibility and practicability in daily school routine. Methods and results: The intervention 'Eigenständig werden 5+6' consists of 14 teaching units evenly distributed over grades 5 and 6 which are interactively delivered, and a parent component. Programme effects are studied in a four wave cluster randomised controlled trial with two arms, an intervention and a control group. Self-completed questionnaires from students and teachers are collected by trained research staff. 45 schools, 172 classes and 3444 students with a mean age of 10.37 years (SD=0.59) and 47.9% girls from four federal states in Germany were assessed at baseline. 1685 students in 81 classes were assigned to intervention classes, 1759 students in 91 classes to the control arm. No differences between conditions were found for age, gender, immigration background, socioeconomic status, substance use or life skills at baseline. Exceptions were higher self-efficacy (t(3438)=2.34, p=0.02, d=0.08) and empathy (t(3302)=2.4, p=0.02, d=0.09) in the control group, whereas class climate seemed better in the intervention group (t(3037)=2.01, p=0.05, d=0.07), but effect sizes state marginal differences. Conclusion: Baseline data suggest that the initial conditions are favourable for testing programme efficacy since distribution of baseline levels of the outcomes did not differ in the intervention and control groups, except for negligible differences between self-efficacy and empathy, which were higher in the control group, and class climate, which was higher in the intervention group.

This study uses 1989-2005 data for the Seattle metropolitan area to test the natural vacancy rate hypothesis for rental housing markets using a new methodology. Findings support the existence of a natural vacancy rate for apartments that varies over time, and in some cases across apartment submarkets. Results show a decline in the natural vacancy rate in the time period following the introduction and growth of the Web. Results also show significant differences in natural vacancy rates for different geographic subareas. No significant differences in the natural vacancy rate are found for different apartment types.

Purpose - The paper seeks to explore the nature of a collaborative relationship among school and academic librarians in order to enhance the information literacy skills of students as they matriculate to college. Design/methodology/approach - The paper discusses collaboration among school librarians in Madison County, Illinois and one academic library. The major reasons for creating these partnerships and the critical success factors of the project are also discussed. Findings - The academic library's role in facilitating collaboration may be challenging but building partnerships with local school libraries is mutually beneficial. Originality/value - Extracts the valuable lessons learned which will help others to effectively build similar relationships between school and academic librarians. [ABSTRACT FROM AUTHOR]

Factors external to a home's characteristics may influence the sales price. This analysis focuses on Bellingham, Washington, because of several influences including the Canadian economy and nonresidents. First estimated is a constant-quality Bellingham housing price index, which is used as the dependent variable in a reduced-form model of market price to estimate the impact of the exchange rate. The analysis (1984-94) suggests that a 10% rise in the exchange rate leads to a 7.7% rise in Bellingham home prices. Additionally, in 1990, non-county buyers paid 4% to 6% more than county residents and non-county sellers received 6% to 8% less. [ABSTRACT FROM AUTHOR]

Inequality in housing services for renters, owners and all households in the United States is estimated for 1978 and 1985. Hedonic techniques are applied to data from the American Housing Survey to derive values for housing services that include publicly provided as well as subsidized housing. We find significant disparities in housing, but substantially less inequality than in incomes. In 1978 the top decile garnered 19.2% of housing services while the bottom decile received only 5.1%. The trend, however, is toward greater equality in housing with large and statistically significant shifts across all deciles. By 1985 the share of the top decile dropped to 16.3% (a percentage decrease in share of 15.3%) while that of the bottom decile rose to 5.7% (a percentage increase of 11.4%.) [ABSTRACT FROM AUTHOR]

This study provides estimates of the value of the view amenity in single-family residential real estate markets. A focus on Bellingham, Washington, a city with a variety of views, including ocean, lake, and mountain, allows for differentiation of the view amenity by both type and quality. Results from a hedonic model estimated for several recent years suggest that depending on the particular view, willingness to pay for this amenity is quite high. The highest-quality ocean views are found to increase the market price of an otherwise comparable home by almost 60%; the lowest-quality ocean views are found to add about 8%. For ocean views of all quality levels, the value of a view is found to vary inversely with distance from the water. [ABSTRACT FROM AUTHOR]

This paper presents evidence on variation in segregation levels experienced by economic subgroups of blacks in Oakland, California and its surrounding county. The central finding is that in this area, one of the most racially integrated in the USA, higher-income blacks exhibit a substantially higher level of integration with whites than do lower-income blacks. In addition, higher income blacks made more progress toward integration in the 1970s. In the 1980s, however, inequality among blacks declined somewhat as lower middle-income blacks experienced the greatest gains in integration. By 1990, very-high income blacks in Oakland had achieved full integration with whites. While important from a descriptive standpoint, results of this study do not constitute evidence that increased black incomes would eliminate residential segregation. The continued significance of race, even for high-income blacks, is underscored by the finding that their exposure to whites is significantly lower than expected, given the disproportionate presence of whites among high-income households.

This study investigates the influence of foreign investment on U.S. residential real estate values. The study uses the Point Roberts, Washington, residential housing market as its focal point, because the market is dominated by Canadian investors and, thus, provides a very good laboratory environment in which to examine the foreign impact on a U.S. market. Factors that affect residential real estate values in this market include not only the general market supply and demand conditions, but also the exchange rate that is faced by the majority of the buyers and sellers. The findings of this study provide insights relevant to other markets that have many Canadian participants such as the border areas of Michigan and New York and certain markets in Florida. Additionally, the results could have implications for other cross-border markets in the world or any other market where foreigners from a single country or area of the world are a factor. Previous research on foreign residential investment in the United States was conducted by scholars N.G. Miller, M.A. Sklarz and N. Ordway. These authors investigate Japanese purchases of upscale homes and condominiums in Hawaii following the dramatic appreciation of the yen relative to the U.S. dollar during the mid-1980s.

Background: Physical activity during childhood and adolescence is associated with substantial health benefits and tracks into adulthood. Nevertheless, only 22.7% of German adolescents are sufficiently physically active. Thus, the promotion of an active lifestyle in youth is an essential issue of public health.This study will evaluate the implementation and efficacy of the "läuft." program to enhance physical activity in adolescence. "läuft." is a multicomponent school-based program developed on the basis of effective strategies for health interventions and behavioral change.Methods/design: The "läuft." physical activity program targets four different levels. (a) Each student receives a pedometer and documents his/her steps over 12 weeks using an interactive user account on the "läuft." homepage. (b) For classes there will be different competitions, with achieving the most steps in selected weeks, the highest increases of steps and developing the most inventive ideas to promote physical activity in school. Besides, the intervention includes four educational lessons. (c) The headmasters and teaching staff of the participating schools will get information material with suggestions and encouragement to enhance physical activity in school. Participating teachers will be invited to an introductory seminar. (d) Parents will be provided with informational material about the program and will be invited to a parent-teacher conference about the benefits of being physically active and how they can support their children in engaging in a physically active lifestyle.To evaluate the efficacy of the "läuft." physical activity program, a two-arm cluster randomized controlled trial will be conducted in three waves: (1) baseline assessment, January/February 2014, (2) post assessment, June/July 2014 and (3) 12-month follow-up assessment, June/July 2015. Data collection will include physical and medical testing, self-administered questionnaires, group discussions and document analyses.Discussion: "läuft." aims at fostering a physically active lifestyle in adolescence while a considerable decline of physical activity is present. Physical activity programs based in the school setting and following a multicomponent approach have been proven to be most successful. Furthermore, the use of pedometers is promising to enhance physical activity during the entire day and targets a wide range of adolescents regarding fitness and weight.Trial Registration: Current Controlled Trials ISRCTN49482118.
