Experience with a multi-year fleet planning model

The fleet planning problem requires determination of the changing airline fleet mix based on existing traffic levels and projected growth, on the existing fleet, various aircraft types available in the future, and other operational and financial considerations. Several applicable mathematical formulations have been reported. One of these has been programmed for the computer and used by the authors for several years. This paper discusses the application of that model to real airline planning situations. Such practical experience has effected changes in the program and the manner it is used in fleet planning studies.     

Sex-positive criminology: Possibilities for legal and social change

This article provides an introduction to sex-positive criminology and its goals for change. Sex-positive criminology draws from the “thick desire” organizing principle, which is a rights-based approach to human sexuality, as well as from positive sexuality approaches. It also draws from critical, queer, and feminist criminological traditions and abolitionist sensibilities. We discuss examples that pertain to key tenets of sex-positivity: consent and bodily autonomy, education, medical access, harm reduction, and ways to increase agency. Main topics of discussion include addressing deeply harmful and sex-negative laws and policies that perpetuate state violence, such as coerced or forced sterilization, criminalization of abortion and pregnancy loss, sexual and physical assault of sex workers by police, criminalization through medically inaccurate laws, and legislation such as Allow States and Victims to Fight Online Sex Trafficking Act and the Stop Enabling Sex Traffickers Act that puts marginalized populations at risk. Throughout, we reflect on possibilities for sex-positive laws and policies and the social impacts they would have, such as improving health and well-being.     

Parents' beliefs about children's emotions,children's emotion understanding,and classroom adjustment in middle childhood

To explore how parental socialization of emotion may influence children's emotion understanding, which then guides children's interpretations of emotion‐related situations across contexts, we examined the pathways between socialization of emotion and children's adjustment in the classroom, with children's emotion understanding as an intervening variable. Specifically, children's emotion understanding was examined as a mediator of associations between mothers' beliefs about the value and danger of children's emotions and children's adjustment in the classroom within an SEM framework. Classroom adjustment was estimated as a latent variable and included social, emotional, and behavioral indices. Covariates included maternal education, and child gender and ethnicity. Participants were a diverse group of 201 third‐graders (116 African American, 81 European American, 4 Biracial; 48.8% female), their mothers, and teachers. Results revealed that emotion‐related beliefs (value and danger) had no direct influence on classroom adjustment. However, children whose mothers endorsed the belief that emotions are dangerous demonstrated less emotion understanding and were less well‐adjusted in the classroom. Mothers' belief that emotions are valuable was not independently associated with emotion understanding. Findings point to the important role of emotion understanding in children's development across contexts (family, classroom) and developmental domains (social, emotional, behavioral) during the middle childhood years.     

Childcare and parental work schedules: a comparison of childcare arrangements among Finnish,British and Dutch dual-earner families

This study examined the association between parental work schedules and non-parental childcare arrangements among dual-earner families in Finland, the Netherlands and the UK. Data from the ‘Families 24/7’ web survey were used, including 937 parents with children aged 0–12 years. Results showed a negative association between non-standard work and formal childcare across all countries. A similar association was found for using a combination of formal and informal childcare, whereas solely using informal childcare was not associated with work characteristics. Country differences showed that, compared with Finland, the probability of using formal childcare was lower in the Netherlands, whereas the probability of using informal childcare was higher in the UK. Interaction effects showed that the negative association between non-standard work and formal childcare was stronger in the Netherlands, compared with Finland. Also, the positive association between working hours and formal childcare was weaker for Dutch and British parents. This study identified the challenges that parents face when arranging childcare outside of office hours. Although the supply of formal childcare seems to be insufficient, using informal childcare introduces other potential problems. Because a considerable proportion of employees work non-standard hours, governments should help these parents in meeting their need for high quality childcare.     

“Let’s talk about the real issue”: Localized perceptions of environment and implications for ecosocial work practice

ABSTRACT

This interpretive study investigated how residents from socioeconomically challenged communities in North St. Louis understand and make meaning of environmental change and its impact on their well-being. Based on these localized data, we argue that racial minorities facing socioeconomic challenges may experience some environmental issues as less of an immediate concern than violence and racism. However, race and racism shape both the realities of environmental threats as well as residents’ perceptions about environmental injustice in their communities. This study informs ecosocial work practices such as educating communities on local environmental issues and mobilizing community members toward environmental decision-making.

Are midwifery clients in Ontario making informed choices about prenatal screening?

BackgroundInformed choice is often lacking in women's decisions about prenatal screening.AimThe aim of this study is to evaluate how well midwives in Ontario, Canada are facilitating informed choice in this area.MethodsAn Internet-based survey was used to investigate 171 midwifery clients’ knowledge, attitude towards and experience of prenatal genetic screening tests, and to determine the proportion of study participants who made an informed choice about prenatal screening.FindingsAll participants demonstrated adequate knowledge of prenatal screening. The vast majority (93.0%) of participants made an informed choice. Participants who chose to screen had lower knowledge scores than those who opted out of screening. Client satisfaction rates in regard to care received in this area ranged from 97% to 100%.ConclusionsResults of this study suggest that Ontario midwives are effective in conveying information on prenatal genetic screening, contributing to high levels of client knowledge and satisfaction in comparison to similar studies in other jurisdictions.     

Testing Cross-National Conflict Shifting theory: An analysis of Chiquita Brands’ transnational crisis in Colombia

This study uses the Cross-National Conflict Shifting theory to analyze Chiquita Brands’ transnational crisis originated in Colombia with consequences in the United States. The research includes a content analysis and a case study conducted by U.S. and Colombian scholars. This research contributes to the global public relations’ body of knowledge by supporting 9 out of the 10 CNCS theoretical propositions, and further supporting the theory with 3 research questions and 8 hypotheses (2 partially supported, 6 supported).
