This study examines the relationship between gentrification and neighborhood crime rates by measuring the growth and geographic spread of one of gentrification's most prominent symbols: coffee shops. The annual counts of neighborhood coffee shops provide an on–the–ground measure of a particular form of economic development and changing consumption patterns that tap into central theoretical frames within the gentrification literature. Our analysis augments commonly used Census variables with the annual number of coffee shops in a neighborhood to assess the influence of gentrification on three–year homicide and street robbery counts in Chicago. Longitudinal Poisson regression models with neighborhood fixed effects reveal that gentrification is a racialized process, in which the effect of gentrification on crime is different for White gentrifying neighborhoods than for Black gentrifying neighborhoods. An increasing number of coffee shops in a neighborhood is associated with declining homicide rates for White, Hispanic, and Black neighborhoods; however, an increasing number of coffee shops is associated with increasing street robberies in Black gentrifying neighborhoods.

In 2001, California instituted a statewide test measuring English proficiency for English learners, students who are not proficient in English. In 2003 and 2004, nearly 500,000 English learners in grades 1–5 took this test each year. The relationship between bilingual education receipt and English proficiency is estimated using value-added regression models for each section of the test—listening and speaking, reading, and writing. In these regression models, students in bilingual education have substantially lower English proficiency of 0.3 standard deviations or more compared with other English learners in first and second grades. In contrast, the difference between bilingual education and other programs is usually less than 0.1 standard deviations for students in grades 3–5. These results hold for ordinary least squares, school fixed effects, and propensity score models.

One of the most perplexing issues faced by finance managers is to know about the effect of capital structure on the profitability of firm. Many studies have been carried out to examine the effect of capital structure on the profitability of firms, but most of them belong to other parts of the world, and only few studies have been conducted in India. Thus, the present study has been undertaken to evaluate the effect of capital structure on the profitability of Nifty 50 companies listed on National Stock Exchange of India from 2008 – 2017. The data has been analyzed by using descriptive statistics, correlation and multiple panel data regression models. Four different regression models have been used to study the relationship between capital structure and profitability. In these models, we study the individual effect of total debt and total equity ratios on profitability, that is, ROA and ROE. All four models have been tested with pooled OLS, fixed effects, and random effects. We conclude that there is significant positive impact of capital structure on firm’s profitability.

The Relationship

This study uses 1986-2012 National Longitudinal Survey of Youth 1979 cohort data to investigate the relationship between raising children and net worth among younger baby boomer parents. I combine fixed effects and unconditional quantile regression models to estimate changes in net worth associated with having children in different age groups across the wealth distribution. This allows me to test whether standard economic models for savings and consumption over the life course hold for families at different wealth levels. My findings show that the wealth effects of children vary throughout the distribution. Among families at or below the median, children of all ages were associated with wealth declines, likely due to the costs of childrearing. However, at the 75th percentile and above, wealth increased with the presence of younger children but decreased once those children reached age 18. My results, therefore, provide evidence for a saving and investment model of childrearing among wealthier families, but not among families at or below median wealth levels. For these families, the costs of raising children largely outweighed motivations for saving.

This study analyzes the relationship between work inspections—which are a relevant control mechanism of countries’ safety function—and the rate of work accidents in Europe. The empirical application is based on fixed-effects regression models on a sample of 24 European countries for the period 2008-2015. The results confirm the pro-cyclical relationship between the rate of work accidents and economic activity (GDP) among the sampled countries. Additionally, the findings reveal that work inspections are an important control mechanism that significantly contributes to alleviate the rate of work accidents. In line with increased awareness of occupational health and safety (OHS) as a relevant dimension of territories’ productive structures, policy implications and future research avenues are discussed.

Abstract Introduction Literature shows that exercise moderates the relationship between sleep and emotional distress (ED.) However, it is unclear whether different types of exercise, such as aerobic and strengthening, affect this relationship differently. We investigated the moderating role of two types of exercise (aerobic and strengthening) regarding the relationship between ED and sleep. Methods Our analysis was based on data from 2018 National Health Interview Survey (NHIS), a nationally representative study in which 2,814 participants provided all data. Participants were asked 1) “how many days they woke up feeling rested over the past week”, 2) the Kessler 6 scale to determine ED (a score >13 indicates ED), and 3) the average frequency of strengthening or aerobic exercise per week. Logistic regression analyses were performed to determine if the reported days of waking up rested predicted level of ED. We then investigated whether strengthening or aerobic exercise differentially moderated this relationship. Covariates such as age and sex were adjusted in the logistic regression models. Logistic regression analyses were performed to determine if subjective reporting of restful sleep predicted level of ED. We investigated whether strengthening exercise or aerobic exercise differentially moderated this relationship. Covariates such as age and sex were adjusted in the logistic regression models. Results On average, participants reported 4.41 restful nights of sleep (SD =2.41), 3.43 strengthening activities (SD = 3.19,) and 8.47 aerobic activities a week (SD=5.91.) We found a significant association between days over the past week reporting waking up feeling rested and ED outcome according to K6, Χ2(1) = -741, p= <.001. The odds ratio signified a decrease of 52% in ED scores for each unit of restful sleep (OR = .48, (95% CI = .33, .65) p=<.001.) In the logistic regression model with moderation, aerobic exercise had a significant moderation effect, Χ2(1) = .03, p=.04, but strengthening exercise did not. Conclusion We found that restful sleep predicted reduction in ED scores. Aerobic exercise moderated this relationship, while strengthening exercise did not. Further research should investigate the longitudinal effects of exercise type on the relationship between restful sleep and ED.

The European Space Agency Climate Change Initiative Soil Moisture (ESA CCI SM) product provides soil moisture estimates from radar satellite data with a daily temporal resolution. Despite validation exercises with ground data that have been performed since the product’s launch, SM has not yet been consistently related to soil water storage, which is a key step for its application for prediction purposes. This study aimed to analyse the relationship between soil water storage (S), which was obtained from soil water balance computations with ground meteorological data, and soil moisture, which was obtained from radar data, as affected by soil water storage capacity (Smax). As a case study, a 14-year monthly series of soil water storage, produced via soil water balance computations using ground meteorological data from northeast Portugal and Smax from 25 mm to 150 mm, were matched with the corresponding monthly averaged SM product. Linear (I) and logistic (II) regression models relating S with SM were compared. Model performance (r2 in the 0.8–0.9 range) varied non-monotonically with Smax, with it being the highest at an Smax of 50 mm. The logistic model (II) performed better than the linear model (I) in the lower range of Smax. Improvements in model performance obtained with segregation of the data series in two subsets, representing soil water recharge and depletion phases throughout the year, outlined the hysteresis in the relationship between S and SM.

AbstractObjectivesThe results of existing studies on bisphenol A (BPA) and puberty timing did not reach a consensus. Thereby we performed this meta-analytic study to explore the association between BPA exposure in urine and puberty timing.MethodsMeta-analysis of the pooled odds ratios (OR), prevalence ratios (PR) or hazards ratios (HR) with 95% confidence intervals (CI) were calculated and estimated using fixed-effects or random-effects models based on between-study heterogeneity.ResultsA total of 10 studies involving 5621 subjects were finally included. The meta-analysis showed that BPA exposure was weakly associated with thelarche (PR: 0.96, 95% CI: 0.93–0.99), while no association was found between BPA exposure and menarche (HR: 0.99, 95% CI: 0.89–1.12; OR: 1.02, 95% CI: 0.73–1.43), and pubarche (OR: 1.00, 95% CI: 0.79–1.26; PR: 1.00, 95% CI: 0.95–1.05).ConclusionsThere was no strong correlation between BPA exposure and puberty timing. Further studies with large sample sizes are needed to verify the relationship between BPA and puberty timing.

Social media marketing (SMM) is a new field that involves the marketing of goods, services, information, and ideas via online networks and social media. Drawing on the stimulus-organism-response framework, this study aims to examine how social-media-marketing activities (SMMA) affect brand loyalty, brand trust, and revisit intention (returning to the same place in the future) for coffee shops in Northern Cyprus. Empirical evidence was collected from 415 undergraduate students who follow specific coffee shops on Facebook, and a structural equation modeling approach was applied. The results showed a significant positive influence of SMMA on brand loyalty, brand trust, and revisit intention. The findings show that SMMA are a stronger predictor of revisit intention than brand loyalty and brand trust. Furthermore, brand loyalty and brand trust are significant mediators in the relationship between SMMA and revisit intention. Additionally, the sequential mediation effects of brand loyalty and brand trust in the relationship between SMMA and revisit intention are supported. Overall, with effective SMMA from coffee shops on Facebook, the customer grows confidence in the brand, which increases the level of brand loyalty. This, in turn, encourages revisit intention of the customer. As a result, brand executives on social media platforms (in this case, Facebook) should promote specific SMMA for their brands and engage in such activities to creates brand trust and brand loyalty. These findings contribute to the literature by examining the relationship between SMMA and revisit intention and exploring how SMMA affect revisit intention by adding brand loyalty and brand trust as mediators.

Understanding periods of the year associated with higher risk for falling and less physical activity may guide fall prevention and activity promotion for older adults. We examined the relationship between weather and seasons on falls and physical activity in a three-year cohort of older adults with glaucoma. Participants recorded falls information via monthly calendars and participated in four one-week accelerometer trials (baseline and per study year). Across 240 participants, there were 406 falls recorded over 7569 person-months, of which 163 were injurious (40%). In separate multivariable regression models incorporating generalized estimating equations, temperature, precipitation, and seasons were not significantly associated with the odds of falling, average daily steps, or average daily active minutes. However, every 10 °C increase in average daily temperature was associated with 24% higher odds of a fall being injurious, as opposed to non-injurious (p = 0.04). The odds of an injurious fall occurring outdoors, as opposed to indoors, were greater with higher average temperatures (OR per 10 °C = 1.46, p = 0.03) and with the summer season (OR = 2.69 vs. winter, p = 0.03). Falls and physical activity should be understood as year-round issues for older adults, although the likelihood of injury and the location of fall-related injuries may change with warmer season and temperatures.
