Impact of urbanization on the water quality,fish habitat,and fish community of a Lake Ontario marsh,Frenchman’s Bay

Frenchman’s Bay is a barrier beach wetland with a highly urbanized watershed located east of Toronto, along the north shore of Lake Ontario. Degradation of water quality has reduced the historically large stand of emergent vegetation to fringe emergent beds to the north and south of the Bay. Altered hydrology and runoff from the urban watershed and a nearby major highway have resulted in poor water quality, and warmer waters at the northern site. By contrast, the southern site has considerably cleaner and cooler water, as it is influenced by exchange of good-quality water with Lake Ontario. These differences in water quality were reflected in the composition of the fish assemblages that were sampled at the two sites over a 2-year period. Comparisons with past studies indicate that the dominant fish community of Frenchman’s Bay has been relatively stable for the last 20 years. Scores for the Wetland Fish Index, an indicator of wetland condition, were significantly higher in the south site than in the north site, which corresponded to significant differences in Water Quality Index scores. Although the northern portion of Frenchman’s Bay shows clear signs of degradation, the southern portion contains important fish habitat for western Lake Ontario.     

Spatial and Temporal Aspects of Alcohol-Related Crime in a College Town

Objective: The authors aimed to clarify crime "movement" through the city of Madison to focus efforts to address consequences of student drinking. The authors examined all crime reported by police during the 2003 year. Methods: Using geographical information system (GIS) mapping and 2003 crime data from the University of Wisconsin-Madison and the city of Madison, the authors investigated the relationships among high-density alcohol outlets and various city neighborhoods. Results: Different categories of crime showed different temporal and spatial patterns: Serious crimes peaked between 2 and 3AM, coinciding with bar closing time. Less serious crimes peaked between 11PM and midnight. Reports of vandalism peaked in the morning and afternoon. "Hotspots" for different crimes moved throughout the downtown. Results were consistent with problems associated with high-risk student drinking in college communities. Conclusion: These results and maps generated by GIS led directly to changes made by city and university officials to address high-risk drinking.     

Changes in chemical and physical propertiesof stream water across an urban-rural gradient in western Georgia

The Middle Chattahoochee River Watershed in western Georgia is undergoing rapid urban development. Consequently, Georgia’s water quality is threatened by extensive development as well as other land uses such as grazing. Maintenance of stream water quality, as land development occurs, is critical for the protection of drinking water, biotic integrity, and stream morphology. A two-phase, watershed-scale study was established to develop relationships among land use and water quality within western Georgia. During phase 1 (year one), physio-chemical, biological and morphological measurements were taken within 16 sub-watersheds, ranging in size from 500–2500 ha. Nutrient and fecal coliform concentrations within watersheds with impervious surface > 5% often exceeded those in other watersheds during both baseflow and storm flow. Also, fecal coliform bacteria in more urbanized areas often exceeded the US EPA’s standard for recreational waters. During the second phase of the study, models will be tested and calibrated based on newly chosen watersheds.

Prevalence of Elder Mistreatment as Reported by Social Workers in a Probability Sample of Adult Day Health Care Clients

ABSTRACT

There are growing numbers of Adult Day Health Care (ADHC) programs providing needed health services to community-dwelling elderly. Therefore, ADHC staff are in an opportune position to identify and to intervene in suspected elder mistreatment (EM) cases. In this paper, prevalence estimates of EM are reported for a probability sample of ADHC clients in New York State, using data provided during a social worker informant interview. The abuse “signs and symptoms” items in the social worker informant interview schedule were divided into two categories: (1) physical indicators and (2) client's behavioral indicators. Physical indicators included unexplained bruises and welts, unexplained burns, unexplained lacerations or abrasions, human bite marks, and frequent injuries that are “accidental” or “unexplained.” Client's behavioral indicators included apprehension, being frightened, and afraid to go home. EM prevalence for all 8 items was 12.3 percent. When “apprehensive” was excluded, the EM prevalence was 3.6 percent in this sample. These findings suggest that ADHC provides a point of contact for the assessment and intervention of EM that might otherwise be overlooked among elders who are often isolated or homebound.     

Soil health as a predictor of lettuce productivity and quality: A case study of urban vacant lots

Urban agriculture offers a framework for local self-reliance and resilience in cities. However, there is a concern over the capacity of urban soil to provide sustainable and safe food production. We tested the effectiveness of several soil health indicators to predict food crop productivity and quality in vacant lots in a disadvantaged neighborhood in the city of Cleveland, Ohio. We defined soil health as a state of composite well being in terms of biological, chemical, and physical properties of the soil as they relate to crop productivity. Twelve city-owned vacant lots, three close to each of the four city schools, were selected for soil properties and plant growth analyses. Soil samples were analyzed for pH, moisture content (θv), soil texture, soil organic matter (SOM), active carbon (AC), ammonium (NH₄-N), nitrate (NO₃-N), microbial biomass N (MBN), and nematode community parameters including total (TNN), bacteria-feeding (BFN), fungal-feeding (FFN), and plant-parasitic (PPN) nematodes, number of nematode genera (NNG), and nematode food web enrichment index (EI) and structure index (SI). Lettuce was planted in the selected vacant lots and its growth was documented through measures of dry biomass, numbers of leaves/plant, and complementary subjective appearance scores related to physiological status. All measured parameters varied considerably among vacant lots except soil pH. Principal components analysis revealed that among the primary soil physical, chemical, and biological parameters, soil clay, NO₃-N, MBN, SOM, AC, TNN, BFN, FFN, and PPN contributed most to the variance of the entire dataset. There were also several positive correlations among these key soil health predictor variables: AC was positively correlated with clay, SOM, MBN, TNN, BFN, FFN and PPN, and TNN was positively correlated with AC, SOM, MBN, BFN, FFN and PPN. Of the identified primary soil health indicators, only clay, SOM, and MBN positively correlated with lettuce dry biomass, which was also positively correlated with a secondary soil health indicator, the nematode food web EI. Lettuce leaf necrosis was negatively correlated with clay, AC, SOM, MBN, TNN, FFN, and PPN, and the proportion of withered leaves was negatively correlated only with SOM. It is concluded that AC, PPN, TNN, SOM, MBN, clay, and nematode food web EI can serve as important soil health indicators that have potential for predicting crop productivity and quality in urban soils. It is also concluded that lettuce can serve as an important indicator of soil health with respect to crop productivity and quality in vacant lots.     

The role of urban indicators in city management: a proposal for Croatian cities

Cities are dynamic economic and social structures that play a dominant role in both national and international economies. They are centers of population, production, consumption, and development. Cities utilize all advantages of economy of scale, proximity, and concentration. On the other hand, they produce high environmental pressures and diminish thereby the quality of life for urban residents. Indicators (environmental, economic, and governance and management) are seen as a tool that would help policy-makers in formulating urban policy that would lead cities towards sustainability and provide assistance for monitoring their development and municipal performance. The aim of this paper is to consider the role that urban indicators can play in city management. We present basic features of urban indicators that will determine their usefulness in urban management. This paper provides the framework to include environmental and economic indicators, as well as governance and management indicators, in successful urban management.     

Regulating animal health,gender and quality control: A study of veterinary surgeons in Great Britain

This paper explores the validity of performance management regimes for quality assuring animal health regulation by comparing the results of tests for bovine tuberculosis (bTB) between male and female vets. In doing so it hopes to present some practical solutions to the regulation of animal disease and encourage further sociological study of the veterinary profession. Concerns about the quality of animal health regulation by vets have prompted thinking about the role of quality control mechanisms such as performance management systems and performance indicators. To investigate their suitability, bTB testing data from areas with high incidence of bTB in Great Britain were extracted from the Vetnet database. Using the data, a performance indicator ‘reactors per 1000 cattle tested’ was calculated and compared with veterinarians' gender. Results showed statistically significant differences between gender and vets' reactor detection: male vets were more likely to detect animal disease than female vets. The paper considers how the concepts of ‘emotional labour’ and ‘relational distance’ may explain vets' behaviour. The presence of these systematic biases raises questions over the use of performance indicators as means of quality control, and highlights the need for further social scientific analysis of the veterinary profession.     

Quality of Web-based Information on Pathological Gambling

The present study aims to evaluate the quality of web-based information on gambling and to investigate potential content quality indicators. The following key words: gambling, pathological gambling, excessive gambling, gambling problem and gambling addiction were entered into two popular search engines: Google and Yahoo. Websites were assessed with a standardized proforma designed to rate sites on the basis of “accountability”, “presentation”, “interactivity”, “readability” and “content quality”. “Health on the Net” (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. Of the 200 links identified, 75 websites were included. The results of the study indicate low scores on each of the measures. A composite global score appeared as a good content quality indicator. While gambling-related education websites for patients are common, their global quality is poor. There is a need for useful evidence-based information about gambling on the web. As the phenomenon has greatly increased, it could be relevant for Internet sites to improve their content by using global score as a quality indicator.     

Stakeholder driven indicators for eHealth performance management

The goal of the present article is to compile a corpus of indicators of eHealth development evaluation that would essentially reflect stakeholder approaches and complement technical indicators of assessment of an eHealth system. Consequently, the assessment of the development of an eHealth system would reflect stakeholder approaches and become an innovative solution in attempting to improve productivity of IT projects in the field of health care. The compiled minimum set of indicators will be designed to monitor implementation of the national eHealth information system. To ensure reliability of the quality research, the respondents were grouped in accordance to the geographical distribution and diversity of the levels and types of the represented jobs and institutions. The applied analysis implies several managerial insights on the hierarchy of eHealth indicators. These insights may be helpful in recommending priority activities in implementation of an eHealth data system on the national or international level. The research is practically useful as it is the first to deal with the topic in Lithuania and its theoretical and practical aspect are particularly relevant in implementation of an eHealth data system in Lithuania. The eHealth assessment indicators presented in the article may be practically useful in two aspects: (1) as key implementation guidelines facilitating the general course of eHealth system development and (2) as a means to evaluate eHealth outcomes.     

Evaluating housing needs with the use of GIS

Rosario (Argentina) has different levels of housing quality and access to physical and social infrastructure. To assess the needs of newly decentralised districts, it is necessary to supply the municipality with new tools to analyse weaknesses and potentialities. The use of GIS can help in this evaluation. It can be implemented at the Public Housing Service to detect problem areas and improve the allocation of resources by efficiently targeting housing needs. Indicators are used to measure different levels of housing needs and provision of basic services. Spatial inequity related to the access to social infrastructure is calculated for the most disadvantaged groups. Expressed demand is also calculated and compared with the demand derived from the indicators. According to the evaluation it can be concluded that the city of Rosario is facing disparities inside the districts. The combined use of derived demand with expressed demand proves to be efficient to detect cases of housing needs where derived demand via indicators is showing lower levels of demand or hiding the situation completely. The growing demand of GIS tools and the availability of census data in digital format will improve and consolidate the evaluation of housing needs and its effect on spatial inequity.     

Drinking, socioemotional functioning, and academic progress in secondary school

Secondary schools are sites of academic instruction but also contexts of socioemotional development, and the intertwining of these two functions has consequences for adolescents' future health and education. Drawing on nationally representative data from the National Longitudinal Study of Adolescent Health (n = 8,271), this study explored the bidirectional associations among indicators of adolescents' alcohol use and their feelings of social integration at school. Socioemotional problems did not predict increased drinking over time, but drinking predicted declining socioemotional functioning, with negative implications for adolescents' academic grades by the end of high school. These associations, however, were conditioned by aspects of school context, with drinkers feeling more marginalized in schools characterized by dense networks with low rates of drinking.     

Analysis of the non-native flora of Ensenada, a fast growing city in northwestern Baja California

Urbanized areas show a high proportion of non-native plants and can work as dispersal points to the surrounding areas. Ensenada is a fast growing city located in the northwestern peninsula of Baja California (Mexico). It is the southern extreme of a bi-national, coastal urban corridor that extends from Los Angeles, California south to Ensenada. This corridor is part of the biodiversity hotspot of the California Floristic Province. The aim of this study was to analyze the composition and distribution of the spontaneous flora in the city of Ensenada. We systematically sampled two differentiated urban environments, vacant lots and arroyos, in 2006 and 2007. We found a total of 158 plant species, 61% of them were non-native species. Arroyo areas showed higher non-native species richness than vacant lots (21.9 vs. 13.6 species/transect) and could be potential dispersal vectors for non-native species to natural areas outside of the city, or in the reverse direction also.     

A Review of Alcoholism Screening Instruments and Their Appropriateness for Women

Abstract

The purpose of this paper is to review empirical data on currently used alcoholism screening instruments. It is the contention of this article that current established instruments have incorporated items significantly more characteristic of males' alcoholism or late stage problem drinking of women. They omit areas more germane to women's life course experiences, such as reproductive health issues and exposure to physical and sexual abuse. Indicators more appropriate for detecting problem drinking in women are proposed.     

Unhealthy behavior clustering and mental health status in United States college students

Abstract

Objective: Examine the association of health risk behavior clusters with mental health status among US college students. Participants: 105,781?US college students who completed the Spring 2011 National College Health Assessment. Methods: We utilized the latent class analysis to determine clustering of health risk behaviors (alcohol binge drinking, cigarette/marijuana use, insufficient physical activity, and fruit/vegetable consumption), and chi-square and ANOVA analyses to examine associations between the class membership and mental health (mental health diagnoses, psychological symptoms, and self-injurious thoughts/behaviors). Results: Three classes were identified with differing rates of binge drinking, substance use, and insufficient physical activity but similar rates of insufficient fruit/vegetable consumption. Students classified with the highest rates of binge drinking and cigarette/marijuana use had the highest rates across all mental health variables compared to other classes. Conclusions: Students who reported engaging in multiple health risk behaviors, especially high alcohol and cigarette/marijuana use, were also more likely to report poorer mental health.     

The geography of deterrence: exploring the small area effects of sobriety checkpoints on alcohol-impaired collision rates within a city

This article examines alcohol-impaired collision metrics around nine sobriety checkpoint locations in Indianapolis, Indiana, before and after implementation of 22 checkpoints, using a pre/post examination, a pre/post nonequivalent comparison group analysis, and an interrupted time series approach. Traffic safety officials used geographical information system (GIS) analysis to help select checkpoint locations amid high alcohol-related collision clusters, then analyzed possible checkpoint impacts. A post hoc analysis examined counts and rates of impaired collisions before and after checkpoint dates within the 2-mile radius zones around each checkpoint site and compared pre-to-post differences to two similar time-matched control areas without checkpoints. As a group, checkpoint zones showed significant though minor declines in pre-to-post collision counts, and no impairment rate change. Considered together, non-downtown checkpoint zones had more favorable impairment rates than comparison areas. After controlling for collision volume, monthly trend, and locational effects, the interrupted time series analysis found that for all checkpoints the count of impaired collisions in post-checkpoint periods was about 19% less than pre-checkpoint counts.     

Cross-sectoral assessment of public policies in health and the environment: Scenario of the municipalities in the state of Sao Paulo

From the identification of the current and rising demand for integrated solutions by government players, especially at the stage of evaluation of public policies, this paper carried out an cross-sectoral outcome assessment of local government cost-effectiveness in the fields of health and environment. The analysis is based on the amount of resources allocated by each of the 645 municipalities in the state of São Paulo, to each field, involving consolidated evaluation indicators (IDSUS and IAA, respectively). This study required the prior distribution of municipalities in clusters within homogeneous groups previously proposed in IDSUS calculation methodology. The results suggest that the addressed areas are intimately connected, indicating that larger (and better) environmental investments can produce promising outcomes toward health performance. Therefore, there is a demand for integrated public policies in the context of environmental health. Also, there is the indication that the resource management and the proper allocation thereof may be more relevant than the total amount spent; and that lower cost-effectiveness values do not necessarily demonstrate high scores in the assessed performance indicators.     

COMBAT EXPOSURE,CIGARETTE CONSUMPTION,AND SUBSTANCE USE

This study estimates the relationship between combat exposure and several risky health behaviors: cigarette consumption, binge drinking, and drug use. We find that the U.S. active duty military personnel deployed to combat zones with enemy firefight are more likely to subsequently smoke cigarettes, consume alcohol, and use illicit drugs than their counterparts deployed to noncombat operations. Our results suggest that the mental health effects of combat can explain up to two‐thirds of the estimated association between combat exposure and risky health behaviors. (JEL H56, I12)     

Sleep Quality and Alcohol Risk in College Students: Examining the Moderating Effects of Drinking Motives

Abstract

Objective: Sleep problems and alcohol misuse are common issues experienced by college students that can have detrimental effects on overall health. Previous work indicates a strong relationship between poor sleep quality and alcohol risk in this population. This study explored the moderating effect of drinking motives in the relationship between global sleep quality and experience of alcohol-related negative consequences. Participants: College students (N = 1,878) who reported past-month drinking. Methods: Participants completed online surveys assessing sleep and alcohol-related behaviors. Results: Poorer sleep quality and higher drinking motives (coping, conformity, and enhancement) predicted greater alcohol-related consequences, controlling for drinking. Further, coping motives moderated the relationship between sleep quality and consequences such that participants reporting poor sleep and high coping motives experienced heightened levels of consequences. Conclusions: These findings advance the understanding of the relationship between sleep problems and alcohol-related risk and provide implications for targeted campus-based health promotion interventions.
