Further properties of generalized residual designs

The concept of ‘residuation’ is extended so that all ‘generalized residual designs’ (in the sense of Shrinkhande and Singhi) are in fact ‘residual’ with respect to the extended type of residuation. A measure of departure from the usual type of residuation is given in general, and stronger estimates of this measure are given for affine designs.     

The environmental efficiency of well-being: A cross-national analysis

Recent research has conceptualized sustainability as the environmental efficiency of well-being (EWEB). This concept takes into account the benefits societies are able to produce from their demands on the environment. Research along these lines indicates that countries vary widely in the efficiency with which they transform the Earth’s resources into well-being. Here, we take up this finding as a puzzle to be explained. We construct a new measure of EWEB using the ecological footprint per capita (a measure of environmental consumption) and average life satisfaction (a measure of subjective well-being). We draw hypotheses from political economy, modernization, and sustainable consumption theories in the environmental social sciences. Using full information maximum likelihood estimation, we test the effects of climate, political, economic, and social factors on EWEB with a sample of 105 countries. Key findings include a negative quadratic effect of economic development on EWEB, a negative effect of income inequality, and a positive effect of social capital.     

The feminization of bereavement among community-dwelling older adults

We examined gender differences in frequency and sociodemographic predictors of spousal, non-spousal family, and friendship bereavement events among community-dwelling older adults using data from the UAB Study of Aging. Analysis involved a 30-month observation period of 893 subjects. There were significant differences between women and men for all types of loss. Significant differences were also found in the sociodemographic predictors of loss between and within gender categories. This study revealed the extent to which older women disproportionately bear the burden of loss and points to the need for greater attention to bereavement as a women's issue.     

Comparison of bootstrap estimation intervals to forecast arithmetic mean and median air passenger demand

The aim of this paper is to compare passenger (pax) demand between airports based on the arithmetic mean (MPD) and the median pax demand (MePD). A three phases approach is applied. First phase, we use bootstrap procedures to estimate the distribution of the arithmetic MPD and the MePD for each block of routes distance; second phase, we use percentile, standard, bias corrected, and bias corrected accelerated methods to calculate bootstrap confidence bands for the MPD and the MePD; and third phase, we implement Monte Carlo (MC) experiments to analyse the finite sample performance of the applied bootstrap. Our results conclude that it is more meaningful to use the estimation of MePD rather than the estimation of MPD in the air transport industry. By carrying out MC experiments, we demonstrate that the bootstrap methods produce coverages close to the nominal for the MPD and the MePD.     

Researching the links between social-emotional learning and intercultural education: strategies for enacting a culturally relevant teaching

ABSTRACT

This paper examines the links between social-emotional learning (SEL) and intercultural education. The work calls for pedagogical attention to the role of emotions in intercultural education and analyses the role of SEL within the umbrella of intercultural education. It claims that both SEL and intercultural education offer a framework for rethinking and changing curricula, school climates and relationships providing the foundation for quality of education for all. Therefore, this connection is not only critical but also inevitable and desirable. It asserts that SEL in intercultural landscapes is a human right that all students are entitled to, and argues that ignoring this right amounts to a social injustice. Some pedagogical considerations and strategies for enacting a culturally relevant implementation of SEL in intercultural settings will be provided. The purpose of the paper is to inform the debate on the role of emotional aspects in intercultural education, and how to configure culturally responsive teachers.     

The Portuguese Version of the Hartford Geriatric Social Work Competency Scale II – Assessment Subscale: Factor Structure and Psychometric Properties

The current study aimed to test the fit of the Portuguese version of the Hartford Geriatric Social Work Competency Scale II – Assessment subscale (GSWCS-A) and explore its factor structure and psychometric properties in a sample of 534 social workers working in the gerontology field. Confirmatory factor analysis showed that all items presented good factor loadings and that the single-component model fit the data well. The GSWCS-A showed very good internal consistency. Despite the existence of different theoretical perspectives on Social Work, which frame the required competencies for professional practice, the GSWCS-A Portuguese version revealed similitudes with studies conducted in other countries. Nevertheless, the different factor structures (single-component vs. bi-factorial) may indicate that different competencies are being emphasised in terms of professional training. To sum, the GSWCS-A may be a short and useful self-report instrument for addressing social workers’ assessment competencies in the gerontology setting.     

An Institutional Contingency Perspective of Interlocking Directorates

Interlocking directorates, in which companies are linked by the directors that serve on their boards, exist globally. It is an expression of hegemonic power exercised by the elites of a society, and has been studied with great interest by organizational sociologists, management scholars and financial economists. The interest emanates from the effect that interlocks have on wealth creation and distribution, and from the perspective that interlocks can tell us how elites in a society are networked. Although diverse theoretical perspectives have informed the research on interlocking directorates, this review shows that the Anglo‐American perspective dominates. This dominance is notable not only in the volume of Anglo‐American studies, but also in theories employed by international studies. For example, most international studies use agency theory to investigate the welfare implications of interlocks, but many countries do not use the Anglo‐American legal regime, which is the basis for agency theory. This paper expands the theoretical basis of the review to include class hegemony and resource dependence, to articulate better the causes and consequences of interlocks in the international context. The paper also extends theory by showing that institutions have an important influence on interlocks, so that the latter can be welfare‐depleting in one institutional setting, while welfare‐enhancing in another. The review concludes by discussing the implication for future research.

Predicting probabilities for the 2010 FIFA World Cup games using a Poisson-Gamma model

In this paper, we provide probabilistic predictions for soccer games of the 2010 FIFA World Cup modelling the number of goals scored in a game by each team. We use a Poisson distribution for the number of goals for each team in a game, where the scoring rate is considered unknown. We use a Gamma distribution for the scoring rate and the Gamma parameters are chosen using historical data and difference among teams defined by a strength factor for each team. The strength factor is a measure of discrimination among the national teams obtained from their memberships to fuzzy clusters. The clusters are obtained with the use of the Fuzzy C-means algorithm applied to a vector of variables, most of them available on the official FIFA website. Static and dynamic models were used to predict the World Cup outcomes and the performance of our predictions was evaluated using two comparison methods.
