Seasonal comparisons of daily activity budgets of gray squirrels (Sciurus carolinensis) in urban areas

Gray squirrels (Sciurus carolinensis) use trees for various resource needs in urban and nonurban settings; particularly, mast producing trees which are the preferred and supplemental foods for the species. During periods of abundant mast availability, less time will be invested in foraging because of the higher success rate stemming from the increased ability to locate food items. Conversely, in periods of reduced mast availability, more time will be invested in foraging. However, correlations between food availability and foraging effort are only supported under the assumption that gray squirrels rely significantly on mast as a preferred or supplemental food source (Nixon et al, J Wildl Manag 39:1–25, 1975). Therefore, given the seasonal variation in the availability of mast, there should also be correlating seasonal variations in foraging effort. In this paper, we will examine daily and seasonal time-activity budgets of gray squirrels in urban areas. We studied the time-activity budgets of gray squirrels in six urban parks in Baltimore, MD. Seasonal frequencies of activities were expressed as percent occurrence and seasonal differences in activities were analyzed using a Tukey Studentized multiple range test for significance. We found that the activity with highest percent occurrence was forage (2003, summer: 23.8 %, fall: 25.9 %; 2004, summer: 23.1 %, fall: 25.2 %), followed by feed and store, all activities associated with food. Results of the Tukey Studentized multiple range test for seasonal differences of activities yielded significant results (P?P?=?0.003); fall 2003 and fall 2004 (P?=?0.048).     

Struggle for Transdisciplinary Moments: Building Partnerships for Resettlement

The effects of climate change are both acute and chronic, leaving many communities in a perpetual state of uncertainty. For others, there is no such uncertainty—their communities will soon be uninhabitable. Some levels of government have begun to recognize and slowly respond to communities facing the possibilities of relocation. This paper considers the impact of transdisciplinary thinking and collaborative moments in the planning phase of one of the few community-scale managed retreat attempts in the United States. In January 2016, the US Department of Housing and Urban Development (HUD) awarded the state of Louisiana $48.3 million to plan, design, and implement a structured and scalable resettlement with former and current residents of Isle de Jean Charles. The paper uses data from surveys and interviews with the practitioner team, fieldnotes, review of published reports, and a sample of more than 400 media accounts. Our analysis highlights how developing a transdisciplinary process may render a new understanding to the tasks and meanings of planning resettlements in the future.     

Health Insurance and the Aging: Evidence From the <Emphasis Type="Italic">Seguro Popular</Emphasis> Program in Mexico

Aimed at covering the large fraction of workers in the informal sector without access to a social security program, the Mexican public health insurance program Seguro Popular began in 2002 and now reaches more than 50 million individuals. We estimate impacts of Seguro Popular for the population aged 50 and older on a set of indicators related to health care including utilization, diagnostic/preventive tests, and treatment conditional on being ill. Using the longitudinal Mexican Health and Aging Study over the period 2001–2012, we conduct before and after difference-in-difference matching impact estimators. Our results suggest large and important effects of the Program on utilization and diagnostic tests. We find overall smaller effects on the probability of being in treatment for individuals with chronic diseases, but these effects are concentrated in rural areas with relatively more health services versus rural areas with lower levels of health services. These results suggest that, to the extent that health services become more available in rural areas lacking services, effects of health insurance may increase.     

‘All in all it is just a judgement call’: issues surrounding sexual consent in young people’s heterosexual encounters

In the UK, there has been growing concern about young people’s understanding of sexual consent, with the views of young people themselves often lost in academic and educational policy debates. However, the focus on high rates of sexual violence has meant a lack of attention on the everyday negotiation of consensual heterosexual activity, leading to assumptions being made regarding young people’s lack of understanding of sexual consent. This paper emerges from a wider study of over 500 young people which sought to uncover their understanding of the issues. Drawing on data from workshops and the open text responses to an on-line survey the findings presented in this paper show that the majority of heterosexual young people understood the complexity of sexual consent as an embodied process, which can be difficult to define, talk about or practice uniformly. This complex understanding, in which sexual consent is a continuum rather than a dichotomy, has implications for sexual education initiatives. We argue that it is only by providing a closer understanding of how – within consensual sexual activities – young people understand and enact sexual consent through a range of embodied communication strategies that education surrounding sexual assault will become meaningful.

Is Self‐Compassion Selfish? The Development of Self‐Compassion,Empathy, and Prosocial Behavior in Adolescence

Both self‐compassion and empathy have been theorized to promote prosociality in youth, but there is little longitudinal data examining this possibility. We assessed self‐compassion, empathy, and peer‐rated prosociality yearly, in a cohort of 2,078 youth across 17 schools (M age at T1 = 14.65 years; 49.2% female), as they progressed from Grade 9–12. We utilized multi‐level modeling to predict prosocial behavior, nested within students, classes, and schools. We found that self‐compassion and empathy uniquely predicted peer‐rated prosocial behavior. However, only empathy predicted increases in prosocial behavior across time. While self‐compassion is not selfish, it does not appear to facilitate the development of kindness toward adolescent peers. Self‐compassion may help to buffer against possible negative effects of empathic distress.     

Working together, working apart: management culture in a manufacturing firm

This paper presents a case study of management culture in a manufacturing organisation. Its general aim is to assess the usefulness of the concept ‘culture’ as it applies to organisations. After first establishing that the organisational members had a sense that their organisation was an unique ‘family’ the article then proceeds to argue that this ‘togetherness’ was, in many contexts, divided. Managers also had a series of conflictual orientations to other members that were partially defined by the managers organisational role but were also underwritten by assumptions about organisational history, community, biography and profession. The paper concludes by suggesting that, at this level of analysis, managers are not often an unified block with a common identity and that management culture is hence best seen as a map of oppositions and commonalities that reflects the wider culture that the organisation is a part of.     

Economic Partisan Advantages in Congressional Contests: 1938-1978

Two broad categories of variables have been used to explainthe dynamics of national forces on congressional elections:presidential and party-related forces. Present research hasemphasized presidential forces in analyzing congressional electionoutcomes, especially with respect to the impact of economicconditions, but this emphasis has resulted in a lack of attentionto other variables that are linked to the major parties ratherthan incumbent presidents. Meaningful empirical relationshipsmay have been inadvertently disregarded because they contradictexpectations derived from an "incumbency hypothesis." This articlesuggests that there are party-related forces operating on congressionalelections, aside from party affiliation, that provide consistentand long-term electoral advantages to candidates of the parties,irrespective of which party controls the presidency. We arguethat the economic policy emphases and historical records ofthe major parties interact with economic conditions such asunemployment and inflation to yield advantages that accrue tothe candidates at election time; these effects are termed economicpartisan advantages.
