Students selling sex: marketisation,higher education and consumption

Robust academic research on the topic of students involved in the sex industry is in its infancy, yet the relationship appears consistent and permanent. This paper draws on findings from the largest study into the stripping industry in the United Kingdom to explore the relationships between students, sex work and consumption. To make sense of the relationship between students and participation in the sex industry, a deeper understanding of other social and cultural processes is needed. In this discussion we argue that the following points are relevant and interlinked: changes to the nature of sexual commerce and sexual consumption as they become part of the marketplace; changes in social attitudes and the rise of ‘respectability’ in sexual commerce; the ‘pleasure dynamic’ amongst students; and changes in the higher education structure that place students as consumers as well as financially fragile. We set out a future research agenda given that this relationship is set to grow as the individual bares the cost of higher education.     

Queering Constructs: Proposing a Dynamic Gender and Sexuality Model

Abstract

Higher education educators commonly understand social identities, including gender, to be fluid and dynamic. Lev's (2004) model of four components of sexual identity is commonly used to demonstrate the fluidity of sex, gender, and sexuality for individuals, but it does little to address the fixedness of those constructs. Through a multipronged intersectional framework and by centering trans* -students, this article proposes a more dynamic model for gender and sexuality.     

Use of sexuality-focused entertainment media in sex education

The literature on the impact of entertainment media on sex education is typically pathology-focused, unclear regarding the effects of such usage, and void of dialogue between those who actually work in the areas of sexuality education and entertainment. To address this gap, this paper is the product of joint authorship between media figures from varied sexually-focused programming fields and academics who teach and conduct research in the areas of sexuality and relational health. The authors focus on the role that various forms of entertainment media play in educating members of the public and college classrooms in the areas of sex and sexuality. Additionally, examples of the inclusion of entertainment media in educational contexts are discussed.     

Using sexually explicit material in a therapeutic context

For most of us, sex is a subjective, lived experience that is as unique as our genetic make-up, our upbringing, our thoughts, values, feelings, beliefs and ideas. It is through our erotic interactions, or the absence thereof, that we form aspects of our fluid and mutable erotic paths and identities. Despite the proliferation of sexual imagery throughout our culture, many of us still struggle with what sex means to us, what we do, how we experience it and what that says about who we are as people. Some who struggle with this may seek the services of a psychosexual sex therapist. This paper aims to explain how such services function, why they are necessary and how the use of sexually explicit material, in some psychosexual therapeutic contexts, can help unravel the mixed responses we have to sex and our social conditioning, and enhance our overall relationship to eroticism, pleasure and general well-being.

军人心理情绪稳定性测试仪的研制

未来战争的较量,军人心理素质将发挥重要的作用。目前对心理情绪稳定性的衡量、训练还停留在定性层面,如何量化军人的心理情绪稳定性,强化心理情绪稳定性训练,是急需解决的问题。军人心理情绪稳定性测试仪通过采集受测试军人的心理情绪稳定性数据,经过科学的统计、计算、比对,通过心理测试科学算法来量化个人的心理情绪稳定性、认知能力等心理参数,从而准确评估受测者的心理素质,为进行心理训练和辅导提供可靠依据。     

Joint trajectories of behavioral,affective, and cognitive engagement in elementary school

The aim of the present study was to model student trajectories of behavioral, affective, and cognitive engagement from Grade 3 to Grade 6. The authors also examined whether teachers perceptions could predict student trajectory membership. The authors collected data from a sample of 831 students and 152 teachers. Using multiple-process growth mixture modeling, they identified 5 distinct trajectories of student engagement. Although a large majority of children presented a stable and high level of engagement on the three dimensions over time, more than one third of them showed a lower or changing level of engagement as the years progressed. These students were more likely to be boys and to be perceived by teachers as being less engaged. They also present more learning or behavioral problems and share less positive relationships with teachers. The results support the need to consider group-based differences when designing and adapting prevention and intervention strategies to favor student engagement.     

Renewed commitments in a time of vigilance: sexuality education in the USA*

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment.     

Honey-bee mating optimization (HBMO) algorithm for optimal reservoir operation

In recent years, evolutionary and meta-heuristic algorithms have been extensively used as search and optimization tools in various problem domains, including science, commerce, and engineering. Ease of use, broad applicability, and global perspective may be considered as the primary reason for their success. The honey-bee mating process has been considered as a typical swarm-based approach to optimization, in which the search algorithm is inspired by the process of real honey-bee mating. In this paper, the honey-bee mating optimization (HBMO) algorithm is presented and tested with a nonlinear, continuous constrained problem with continuous decision and state variables to demonstrate the efficiency of the algorithm in handling the single reservoir operation optimization problems. It is shown that the performance of the model is quite comparable with the results of the well-developed traditional linear programming (LP) solvers such as LINGO 8.0. Results obtained are quite promising and compare well with the final results of the other approach.
