A methodology for connecting user centered design (UCD) with eco-design. The possibility of migration of products to services based on the user acceptance

The consumer products generation is one of the main engines that fuel the planet's environmental problems, reduction of environmental impacts associated with the products has been studied from various aspects between them, the supply of products for public consumption instead of private, seeking to meet the needs of the community by establishing programs for sharing single product. It has been detected a problematic issues linked to this strategy, where the user acceptance of this new way of living together with the products must be achieved. The arguments here presented seek to identify user perception of such proposals and their possible acceptance throughout strategies from the User Centered Design (UCD).     

Predicting supportive behavior of parents and siblings to a family member with intellectual disability living in institutional care

This feasibility study examines whether the theory of planned behavior can predict supportive behavior provided by either parents to their offspring-or adult siblings to their brothers and sisters-with an intellectual disability living in 2 Israeli institutional care facilities. Participants were 67 parents and 63 siblings who were interviewed at baseline regarding their intentions to visit their offspring or sibling in the institutional care facility, to contact the caregiving staff, and to accept visits at home. Parents' and siblings' behavior regarding visitation and supportive behavior was examined after 6 months by caregiving staff. Core findings indicated that subjective norms in siblings and parents predicted frequency of home visits. Perceived behavioral control predicted frequency of contact between siblings and staff. Differences between parents and siblings regarding their supportive behaviors are discussed with respect to social work practice.     

Work Hours,Schedules, and Insufficient Sleep Among Mothers and Their Young Children

Studies have linked parents' employment, work hours, and work schedules to their own sleep quality and quantity, but it is unclear whether these associations extend to children. The authors used data from the 5‐year in‐home survey of the Fragile Families and Child Wellbeing Study (N = 1,818) to examine the associations between maternal work hours and schedule and insufficient sleep among disadvantaged mothers and their young children. They found that mothers who worked more than 35 hours per week were more likely to experience insufficient sleep compared to mothers who worked fewer hours, whereas children were more likely to experience insufficient sleep when their mothers worked between 20 and 40 hours. Nonstandard work schedules were associated with an increased likelihood of insufficient sleep for mothers but not their children. The results highlight a potentially difficult balance between work and family for many disadvantaged working mothers in the United States.     

Gay, Orthodox, and trembling: the rise of Jewish Orthodox gay consciousness, 1970s-2000s

In 2001, the documentary movie, Trembling Before God, was played in Jewish and gay film festivals around the world, provoking strong emotional reactions. Trembling Before God comprises interviews with Orthodox Jewish gay and lesbian persons who vividly and movingly describe their struggles to live their lives as observant Jewish people, being faithful at the same time to their sexual desires and their religious tradition. Almost all the people interviewed in the movie expressed mixed emotions: love towards their tradition and attachment to their community of faith, coupled with resentment against a community, which in their eyes failed to respond with understanding to their emotional needs, thus adding to their pain. This article aims to modify the picture portrayed in the movie. The dilemmas and struggles of gays and lesbians who live their lives in Orthodox Jewish communities are indeed real. Orthodox gays and lesbians experience a greater dissonance between their sexuality and the values of their community and therefore face more anxieties and inner turmoils than gays and lesbians who live in more permissive environments. The struggles of gay and lesbian Orthodox Jews, however, are not necessarily greater than those of gays and lesbians who live their lives in other conservative communities. In fact, while it is almost impossible to be a sexually active gay or lesbian and a practicing Southern Baptist, Seventh-Day Adventist, Jehovah's Witness, or Mormon, it is not impossible for gays and lesbians to live their lives in an Orthodox Jewish environment. Amazingly, since the 1970s, thousands of gays and lesbians have given up on liberal environments and joined the ranks of traditionalist Jewish congregations.     

Observing Erotic Videos With Heterosexual Content Induces Different Cerebral Responses in Homosexual and Heterosexual Men

ABSTRACT

To determine the cerebral functionality associated with the perception and processing of erotic stimuli in men with different sexual orientation, this work evaluated the electroencephalographic activity (EEG) from several cortical areas, as well as subjective arousal in homosexual and heterosexual men during observation of an erotic film with heterosexual content. The heterosexual men rated the erotic video with higher general and sexual arousal than the homosexual participants. During observation of the neutral and erotic videos, both groups showed a decreased amplitude of the alpha band in prefrontal and parietal cortices, indicating increased attention. When watching the erotic video, the homosexual men showed an increased amplitude of the theta and fast bands only in the prefrontal cortex, which could be related to the cognitive processing of the erotic stimulus. These EEG results should broaden our knowledge of the cortical mechanisms related to the different perception and processing of erotic stimuli in men with different sexual orientations.     

“Todo ha sido a pulmón”: Community organizing after disaster in Puerto Rico

ABSTRACT

In this Notes from the Field, we highlight the work of community based organizations that filled essential gaps in the disaster recovery efforts in Puerto Rico for communities that were heavily damaged by Hurricane Maria yet received little formal government aid. We describe community mobilizing and organizing efforts and identify key lessons for eco-social work practice. As disaster risk increases with climate change, community led efforts are likely to prove vital for the effective protection of the most vulnerable population groups.     

The Role of Catchment Areas on School Segregation by Economic,Social and Cultural Characteristics

This research analyses the socioeconomic and cultural segregation of students across school catchment areas using census data for the students in their second year of secondary education in Andalusia (the most populated region in Spain). The main methodology used is the Mutual Information Index, which satisfies all the desirable properties for measuring segregation. Concretely, we draw upon the additive decomposability property, which decomposes the segregation of students across schools into the different levels in which schools can be grouped, that is, catchment areas and, within catchment areas, by source of funding (public and semiprivate schools). We found that school segregation is greater than catchment areas’ segregation. Additionally, statistically significant correlations are found between the level of segregation within the catchment areas and factors such as size of the catchment area, parental level of education and size of the municipality where the school is located.

     

Matrix variate Macdonald distribution

Abstract

In this article, we generalize the univariate Macdonald distribution to the matrix case and give its derivation using matrix variate gamma distribution. We study several properties such as cumulative distribution function, marginal distribution of submatrix, triangular factorization, moment generating function, and expected values of several functions of the Macdonald matrix. Some of these results are expressed in terms of special functions of matrix arguments and zonal polynomials.
