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.     

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.     

‘I’m Black and I’m Proud’: A Majority Ecological Context Protects Affective Aspects of Black Identity Under Stereotype Threat

We provide evidence that stereotype threat, a phenomenon that causes stigmatized individuals to experience group-based evaluative concerns (Steele in Am Psychol 52:613–629, 1997; Whistling Vivaldi and other clues to how stereotypes affect us, W.W. Norton, New York, 2010), impacts affective aspects of Black identity as a function of majority versus minority ecological contexts. Black/African-American students, enrolled in either Africana Studies (Black ecological majority) or Psychology (Black ecological minority), completed private and public regard subscales from the Multidimensional Inventory of Black Identity (Sellers et al. in Pers Soc Psychol Rev 2:18–39, 1998) at baseline (Time 1) and after being randomly assigned to a stereotype threat or no-threat/control condition (Time 2). In threat, participants were introduced to a ‘puzzle’ task as diagnostic of intellectual abilities, whereas in no-threat the same task was introduced as culture fair, such that people from different racial/ethnic groups had performed similarly on this task in the past. In Psychology, students under threat exhibited a simultaneous decrease and increase in private and public regard, respectively, a pattern shown in the literature to be associated with discrimination-based distress and lesser well-being in Black ecological minority environments. In contrast, Africana Studies students’ racial identity under threat remained intact. We discuss the protective effects of Africana Studies on racial identity and implications for educational reform.

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.     

Ergonomic analysis of the work conditions of porters and owners of the Supply Center of Campinas, SP

Transforming work conditions is part of the ergonomic action that should help to improve work situations that brings risks to the workers health. six workers were observed in different locations of the supply center (Central Free Market, Free Market 2, Flowers Market and Permanent Shed 4). During the observation of workers to the Ergonomic Analysis of Work - AET (Rohmert and Landau) was performed. The workers were divided into two groups: porters and owners. The porters were the most susceptible to the risks of work and minor accidents with sharp wood from boxes or even risk of traffic accidents as pedestrians. However, regarding the use of mental ability for negotiations, use of computers and organizing and planning the establishment of work, the owners were the ones that most time played these activities. The ergonomics advocates work that can be transformed and that favors employee and employer. It is, therefore, intended to redefine the strategies that are embedded into the organizational structure of work.
