A comparison of Mediterranean Gecko (Hemidactylus turcicus) populations in two temperate zone urban habitats

Urban ecosystems represent unique habitats that might be more or less suitable than natural systems for many species. The Mediterranean Gecko, Hemidactylus turcicus is a synanthropic species that has successfully colonized many urban and suburban areas outside its natural range. In the United States, H. turcicus has been found predominantly in southern states on exterior surfaces of buildings. We compared population density, demographics, and extent of dispersal of populations of H. turcicus at two anthropogenic sites in a temperate region of the United States. The University of Central Oklahoma (UCO) had higher building density and greater cover by anthropogenic surfaces and the Oklahoma City Zoo (ZOO) had lower building density and greater cover by vegetation. Mark and recapture sampling was conducted at UCO from 2006 to 2007 and during 2008 at ZOO. The sizes of the populations at the two sites were estimated using the Schnabel method and population densities were calculated using those estimates. Age class of captured animals, sex of adults, and gravid status of adult females were determined at both sites. We assumed that greater exterior wall surface area of individual buildings at UCO and greater land cover by anthropogenic surfaces might 1) reduce population density and 2) facilitate dispersal there relative to the ZOO. Population sizes and density in animals per ha of land and building cover and demographics were similar at the two sites. Population density per ha of building exterior wall area was higher at ZOO than at UCO. The higher density of animals on buildings, lower proportion of subadults in the population and lower maximum dispersal distance at ZOO suggest that successful diffusion dispersal might be limited at that site relative to UCO.     

Jailhouse Islamophobia: Anti-Muslim Discrimination in American Prisons

The post 9/11 surge in America’s Muslim prison population has stirred deep-seated fears, including the specter that American prisons will become a breeding system for “radicalized Islam.” With these fears have come restraints on Muslim religious expression. Mistreatment of Muslim prisoners violates the Religious Land Use and Institutionalized Persons Act of 2000 (RLUIPA), which Congress passed in part to protect prisoners from religious discrimination. Despite RLUIPA, prisoners still face the same challenge that preceded the legislation. Ironically, while Congress directed courts to apply strict scrutiny to these cases, the courts continue to reject most claims. One reason is that many courts are applying a diluted form of the legal standard. Indeed, the “war on terror” has justified increasing deference to prison administration to the detriment of incarcerated Muslims and religious freedom.

The identification of recreational counties in nonmetropolitan areas of the USA

Nonmetropolitan counties in the USA with significant concentrations of recreational activity are identified using a combination of quantitative and contextual indicators. The 285 counties identified as recreational encompass 12 percent of the nonmetropolitan counties and 15 percent of the 1990 nonmetropolitan population. Population growth in such counties has consistently exceeded that in other nonmetropolitan areas as well as that in metropolitan areas. Net migration accounted for most of the population growth in such counties during the 24 years considered. The revenue and expenditure patterns of local governments in recreational counties differs from those elsewhere suggesting significant policy concerns.     

Socio-economic status, permanent income, and fertility: a latent-variable approach

This paper examines how permanent income and other components of socio-economic status (SES) are related to fertility in less developed countries. Because permanent income cannot be measured directly, we employ a latent-variable method. We compare our results with those of the more common proxy-variable method and investigate the consequences of not accounting for measurement error. Using data from Ghana and Peru, we find that permanent income has a large, negative influence on fertility and that research must take the latent nature of permanent income into account to uncover its influence. Controlling for measurement error in the proxies for permanent income can also lead to substantial changes in the estimated effects of control variables. Finally, we examine which of the common proxies for permanent income most closely capture the concept. The results have implications beyond this specific dependent variable, providing evidence on the sensitivity of microanalyses to the treatment of long-term economic status.     

Joint Lot Sizing and Scheduling of Multiple Items with Sequence-Dependent Setup Costs

The objective of this research is to investigate the effects of setup-cost estimating methods on the lot sizing and scheduling of multiple products in multiple periods. These initial setup cost estimators (ISCEs) are used to estimate sequence-independent initial setup costs from sequence-dependent setup costs. A search of the literature reveals that, although sequence-dependent setup costs are frequently found in practice and ISCEs are frequently used, there is a dearth of research concerning the effect of using ISCEs. After a review of the literature, a mixed integer formulation of the joint problem of lot sizing and scheduling is presented, followed by a discussion of the difficulty in solving the formulation. Next, the six ISCEs evaluated are presented. These ISCEs range from simple (select the minimum setup cost) to complex (use the branch-and-bound solution to a traveling salesman-type problem). Each ISCE is evaluated using a full factorial design with five independent variables: demand distribution (three levels), demand trend (three levels), setup to inventory level (six levels), setup distribution (three levels), and setup variability (two levels). Two hypotheses are researched. Do the more computationally complex ISCEs produce lower overall costs than do the simpler ISCEs? Does the reduction in total cost justify the additional computation cost? The results of this study demonstrate that it may be incorrect to use “conventional wisdom'’when selecting an ISCE.     

A multiple range procedure for independent proportions

A multiple range procedure is proposed for comparing proportions arising from several independent groups each of equal sample size n. The procedure is then applied to a hypothetical set of data for the purpose of illustration.     

Police encounters among a community sample of children and youth accessing mental health services

Generally, within the Canadian context, scholarship on police encounters with persons living with mental illness has focused on the experiences of adults and not children and youth. In this article, we present preliminary work of a secondary data analysis of intake statistics collected over a 5-year period (2009–2014) and a thematic content analysis of qualitative intake notes collected over a 2-year period (2009–2011) about police involvement among a community sample of children and youth accessing mental health services. Of 8,920 intakes completed, 1,449 children and youth, birth to 24 years old, had had police involvement at the time of accessing mental health services. Over the 5 years, the average number of young people with police involvement at the time of accessing mental health services was 16%, or one in six children and youth. Analysis of the qualitative intake notes revealed two main reasons for police involvement: (1) support in the home for a distressed child, and (2) concerns about a child’s conduct and behaviors in the community. The implications for social work practice and future research are discussed.     

Promoting supervisory practice change in public child welfare: lessons from university/agency collaborative research in four states

This article describes qualitative findings regarding lessons learned from research and demonstration projects in four states focused on the implementation of clinical supervision within their public child welfare agencies. This was part of a larger mixed methods study of the effectiveness of these new clinical supervision models on practice, organizational, and client outcomes. Themes from 15 focus groups with frontline supervisors participating in the projects are provided; they focused on the challenges experienced while participating and working to use clinical supervision techniques, recommendations regarding implementing such projects in the public child welfare environment, and those aspects of the implementation that were most effective in supporting their work. These themes provide direction for states and localities wishing to shift frontline supervision to a more clinical model within the public child welfare setting.
