Impact of urban structure on avian diversity along the Truckee River, USA

Urban riparian habitats are potentially important resources for native birds in arid ecosystems. Most studies have assessed the value of urban riparian habitat in terms of vegetation and natural resources; however, the surrounding land use and infrastructure may determine the viability of urban habitat. We studied the impact of urban structure, the combination of land use, infrastructure and vegetation variables that work together to shape the urban environment, on avian riparian habitat in the Truckee Meadows, Nevada, USA. Land use and infrastructure explained avian species richness and abundance better than local vegetation alone, but community resemblance was more strongly correlated to vegetation. Avian species guilds responded differentially to surrounding land use, suggesting there may be a functional difference between land use types. The best models for bird diversity used urban structure (both land use and vegetation) to describe potential habitat. Urban structure describes urban habitat in ways that vegetation variables alone cannot. Studies that ignore land use and infrastructure and other socioeconomic variables are likely missing key functional differences within urban ecosystems, and may miss the potential for compatible development that encourages both biodiversity and urban growth.     

Kazakhstan: constructing identity in a post-Soviet society

One of the problems with the now independent countries of Central Asia is that they have little history of independent statehood and even less experience of any ideological context that legitimizes a specific set of political arrangements, other than the discredited Marxist model of the Soviet system. Neither habit nor attachment to a coherent set of political ideals is very helpful as the basis for individual identification with or support of the State. Perhaps as a consequence, political operatives in Central Asian countries have opted to emphasize the centrality of ethnicity to legitimize their current political arrangements. But in Kazakhstan this presents a potential problem – the country is ethnically very diverse, has a large Russian/Slavic population and the ‘core nation’ of ethnic Kazakhs comprises a bare majority of Kazakh citizens. We utilize survey research to test the influence such factors as ethnicity, religion and other nexus of identity have on feelings of attachment to the state. Our findings indicate that identifying as ‘Kazakh’ indeed has a positive effect on identification with the state, as do identifying as Sunni Muslim and ‘Asian’. However, institutional trust and economic well-being are also positive influences on affective regard for the state, allowing an opening for broadening and deepening the basis for state legitimacy.     

Differences in Cognitive Distortions Between Pathological and Non-Pathological Gamblers with Preferences for Chance or Skill Games

Cognitive distortions have been thought to play an important role in the development and maintenance of pathological gambling. The present study investigated whether severity of gambling problems and gamblers’ preference for chance or skill games were related to two sub-factors of cognitive distortions as measured by the Gamblers Belief Questionnaire: Luck/Perseverance, which reflects an individual’s perception that chance is favorable to him/her, and Illusion of Control, which reflects an individual’s perception that his/her behavior influences chance occurrences. Participants (N = 166) were recruited from a race track (n = 79), off-course betting facilities (n = 50) and from an online treatment program for problem gamblers (n = 49). Gambling severity was measured by the South Oaks Gambling Screen, and 73 were classified as pathological gamblers whereas 93 were classified as non-pathological gamblers. The present study supports previous proposals that cognitive distortions are core processes related to gambling behavior as pathological gamblers reported more cognitive distortions than did non-pathological gamblers. A preference for skill games was also associated with greater Illusion of Control compared to a preference for chance games. For gamblers preferring skill games there were no differences in Luck/Perseverance or Illusion of Control between pathological and non-pathological gamblers.     

WHY ZERO TOLERANCE OF MISCONDUCT IS UNDESIRABLE IN CONTESTS

Competition can foster misconduct in any circumstance where the organizer of a contest cannot perfectly monitor contestants' actions or when doing so is prohibitively costly. Although misconduct comprises all actions that are contrary to the interest of the organizer, it is not necessarily the case that it is optimal to prohibit all such behavior. In this paper, we determine the equilibrium level of misconduct chosen by players in a symmetric rank‐order tournament between two competitors in which the organizer tolerates some level of misconduct. In addition to showing that zero tolerance may not minimize the level of misconduct in equilibrium, we show that there exists a range of tolerated misconduct where a symmetric mixed strategy equilibrium exists with players cheating (i.e., misconduct above the tolerated level) with some probability. When the gain from misconduct is uncertain and unknown the contest organizer faces a tradeoff: tolerating more misconduct will reduce such behavior when the state of temptation is high, but increase it when temptation is low.

Natural experiment methodology for research: a review of how different methods can support real-world research

In particular research domains, the randomized control trial (RCT) is considered to be the only means for obtaining reliable estimates of the true impact of an intervention. However, an RCT design would often not be considered ethical, politically feasible, or appropriate for evaluating the impact of many policy, programme, or structural changes common in public health research. As such, researchers must use alternative yet robust research methods for determining the impact of such interventions. The evaluation of natural experiments (i.e. an intervention not controlled or manipulated by researchers), using various experimental and non-experimental design options can provide an alternative to the RCT. The following review highlights (a) the importance of evaluating natural experiments; (b) design considerations associated with evaluating natural experiments; (c) methods for reducing bias in natural experimental studies; and (d) the potential benefits of targeted systems to enable natural experiments in emerging priority domains moving forward.     

Teaching Ethnographic Research Methods in Social Work

This article describes a social work course that incorporates instruction on ethnographic research, a contemporary qualitative methodology. The authors describe each of the seven course modules used to teach students ethnographic research methods. They cover sampling strategies, data collection, data analysis, theory development, presentation of findings, and practical application within a clinical setting. Findings from student evaluations of the usefulness and relevance of the course are also described, as are the educational and research implications of teaching ethnographic research methods within a social work curriculum.     

The Hospital Foundation Strategy and Performance Relationship

Attracting philanthropic donations is a strategic imperative for many hospitals. A hospital can manage the giving process most effectively by developing a well‐managed hospital foundation. This study examines the hospital foundation strategy and performance relationship. Using a sample of 258 hospital foundations we identified different strategies and significant performance differences among them.
