Social risk assessment and social capital: A significant parameter for the formation of climate change policies

Public policy issues arising from climate change projections are becoming increasingly important in terms of the range and the scope of their effects. In order to effectively confront them it is important to address social, environmental and economic aspects as fully as possible in decision-making processes. In this context, social risk assessment techniques have begun to be applied to explore citizens’ risk perceptions of climate change projections. The present study aims to contribute to this area by examining the influence of four social capital parameters (social trust, institutional trust, social norms and social networks) on public risk perceptions of climate change. An empirical study was conducted for this purpose in Greece's fourth largest city, Heraklion. Results demonstrate that social capital is a significant explanatory parameter for citizens’ risk perceptions. Specifically, individuals with lower levels of social capital tend to perceive higher risks from climate change impacts. The most important parameter explaining this result is the low level of institutional trust, revealing that Heraklion's citizens do not believe that existing public institutions will be able to effectively manage projected climate change impacts.     

Straightforward intermediate rank tensor product smoothing in mixed models

Tensor product smooths provide the natural way of representing smooth interaction terms in regression models because they are invariant to the units in which the covariates are measured, hence avoiding the need for arbitrary decisions about relative scaling of variables. They would also be the natural way to represent smooth interactions in mixed regression models, but for the fact that the tensor product constructions proposed to date are difficult or impossible to estimate using most standard mixed modelling software. This paper proposes a new approach to the construction of tensor product smooths, which allows the smooth to be written as the sum of some fixed effects and some sets of i.i.d. Gaussian random effects: no previously published construction achieves this. Because of the simplicity of this random effects structure, our construction is useable with almost any flexible mixed modelling software, allowing smooth interaction terms to be readily incorporated into any Generalized Linear Mixed Model. To achieve the computationally convenient separation of smoothing penalties, the construction differs from previous tensor product approaches in the penalties used to control smoothness, but the penalties have the advantage over several alternative approaches of being explicitly interpretable in terms of function shape. Like all tensor product smoothing methods, our approach builds up smooth functions of several variables from marginal smooths of lower dimension, but unlike much of the previous literature we treat the general case in which the marginal smooths can be any quadratically penalized basis expansion, and there can be any number of them. We also point out that the imposition of identifiability constraints on smoothers requires more care in the mixed model setting than it would in a simple additive model setting, and show how to deal with the issue. An interesting side effect of our construction is that an ANOVA-decomposition of the smooth can be read off from the estimates, although this is not our primary focus. We were motivated to undertake this work by applied problems in the analysis of abundance survey data, and two examples of this are presented.     

Political Generations in Developing Countries: Evidence and Insights from Algeria

The socialization literature has examined whether individualswho pass through their formative years during definable historicaleras constitute political generations characterized by shareddispositions or collective memories that outlast the eras themselves.Drawing upon 1995 public opinion data from Algeria, we ask whetherpolitical generations are discernible in a non-Western societyin which the government and politics have undergone fundamentaltransformations in character and normative orientation. We findevidence that shared attitudes characterize Algerians who cameof age during the regime of President Houari Boumedienne—astable 13-year period from 1965 to 1978 marked by centralizedpolitical leadership, low grassroots political participation,and state-led socialism. Other cohorts are not similarly distinguishable,however, nor does the Boumedienne cohort differ from otherswith respect to a number of political, economic, and culturalorientations. Like other studies, this research indicates thatsome historical periods produce durable generation effects whileothers do not and that some attitudes acquired during the formativeyears of late adolescence and early adulthood persist over timewhile others do not.     

Ego strength and achievement motivation in pathological gamblers

This paper argues that there area priori reasons to extract measures of ego strength and achievement motivation from the psychometric data base routinely collected from inpatient pathological gambers in order to clarify the meaning of these constructs and to evaluate their roles in personality organization. A sample of 57 subjects engaged in an inpatient treatment program for pathological gamblers was studied using Barron's Ego Strength Scale (ES) from the Minnesota Multiphasic Personality Inventory and two measures of achievement motivation from the California Personality Inventory, Achievement via Conformance (Ac) and Achievement via Independence (Ai). Compared to the standardization group norms on these instruments, pathological gamblers are significantly deficient in both ego strength and one type of achievement motivation, Ac. Clinical impressions of gamblers in treatment suggest that narcissistic characteristics are a major problem in treatment and that future research should attempt further detailed studies of ego structure in order to refine treatment objectives.     

Spouse-aided Therapy and Psychiatric Nursing: A Preliminary Report

The training of psychiatric nurses as behavioural nurse therapists has been successfully established in the U.K. by Marks et al. However, their approach has a number of theoretical and practical limitations, such as a rigid adherence to an illness model of psychiatric disorder. This paper describes and evaluates an approach to the training of psychiatric nurses based on systems theory. Four nurses were trained in the use of Spouse-aided Therapy, a time-limited, goal-orientated outpatient approach to the treatment of married psychiatric patients with persisting psychological disorders. Patients' spouses are involved throughout therapy, with the aim of making full use of resources within marriage which may facilitate patients' recovery. Questionnaire and anecdotal data from 12 patients showed a mean fall of 30% in patients' symptoms and a mean fall of 20% in marital dissatisfaction after therapy. The pattern of results supported a systems theory interpretation of outcome.     

The Welfare Effect of an Additional Child Cannot be Stated Simply and Unequivocally

There is no single calculable welfare effect of an additional person. Rather, there are many different judgments, which may be negative or positive. The welfare effect depends upon the particular economic situation the child will be born into, which point in his life-cycle one refers to, whether he is expected to have a positive effect upon his particular sort of economy and society during and after his lifetime, and most of all, on the kind of welfare criterion used. Furthermore, no matter which welfare criterion is used, the welfare effect of an added individual summarized over time is especially sensitive to the particular assumptions made.     

Perceptions of environmental supports on the physical activity behaviors of university men and women: a preliminary investigation

OBJECTIVE: To examine perception differences between genders of university sidewalks and safety from crime on the physical activity (PA) behaviors of undergraduate students. PARTICIPANTS: Five hundred and sixty undergraduate students participated in this study. METHODS: The authors derived questions from the South Carolina Environmental Supports for Physical Activity Questionnaire (SCESPAQ) and National College Health Risk Behavior Survey (NCHRS) PA module. RESULTS: The authors found a significant mean difference between genders for the Moderate Intensity Item (eg, walking and biking) and the Flexibility Item, t(558)=3.602, p=.001, and t(558)=1.946, p=.050, respectively. Of participants surveyed, 30% of women perceived this campus to be extremely safe compared with 49% of men, t(558)=4.240, p=.001. Gender and the perceptions of sidewalk presence were significantly related (p<.05) to respondents' walking or bicycling patterns. CONCLUSIONS: Perceptions of sidewalks and safety from crime on this university campus were related to students' PA behaviors.     

Perceptions of the availability of recreational physical activity facilities on a university campus

OBJECTIVE: The author's purpose in this study was to assess perceptions of recreational physical activity (PA) facilities on a university campus. PARTICIPANTS: Four-hundred and sixty-seven undergraduate students participated in this study (women = 293; men = 174). RESULTS: The author found a significant percentage difference between women and men concerning the availability of racquetball courts on campus, 47% vs 63%, t (465) = -3.274. The author similarly found a significant percentage difference between women and men's perceptions concerning the availability of tennis courts. Twenty-seven percent of women were unaware or did not know tennis courts were available for PA, in comparison with 19% of men t (465) = -2.413. Awareness of recreational facilities revealed significant differences (Pillai's Trace = .189, p < .05) between freshmen and upperclassmen. Freshmen perceived themselves to have access to fewer recreational facilities on campus. CONCLUSION: More efforts to increase awareness of PA facilities are needed on university campuses.     

Our favourite melodies: musical consumption and teenage lifestyles

The present study explores the determinants and lifestyle correletes of musical preferences among a large sample of high school students in Toronto, Ontario. Our work is informed by theory and research on cultural stratification and adolescent subcultures. In terms of cultural stratification, we engage with Bourdieu's (1984) and Peterson's (1996) conceptualizations of elite taste, while subcultural theory encourages us to focus upon more dissenting tastes and to explore connections between musical tastes and peer group activity. Our findings suggest that racial and ethnic identity, school experiences and cultural capital are significant sources of variation in musical tastes that loosely correspond to existing typologies; they also confirm what has often been inferred - that musical tastes and peer group cultural practices are closely linked. Our findings are then discussed in the light of current debates about the nature and dimensions of listening audiences for music.     

Motivation and Commissioning: Perceived and Expressed Motivations of Care Home Providers

Commissioning of social care for older people has seen major changes since the early 1990s. Considerable responsibility now rests with local authority staff, whose views of care home providers’ motivations, their perceived strengths and weaknesses as service providers, will have a bearing on commissioning decisions. We examine commissioners’ views of provider motivations in eight English local authorities and compare their perceived motivations with providers’ expressed motives. Data were collected through semi‐structured face‐to‐face interviews with commissioners and care home providers. Providers are generally perceived by commissioners as highly altruistic, but also relatively financially motivated individuals. Further analysis revealed significantly different views towards profit‐maximizing, which commissioners perceive as very important, while providers consider it to be of little motivational value. Private sector providers are described by commissioners as significantly more motivated by personal income. Associations are found between commissioners’ perceptions of motivations and the nature of their relationships with providers. Perceptions of providers’ motivations appear important within the commissioning framework.
