30 Days Wild: Development and Evaluation of a Large-Scale Nature Engagement Campaign to Improve Well-Being

There is a need to increase people’s engagement with and connection to nature, both for human well-being and the conservation of nature itself. In order to suggest ways for people to engage with nature and create a wider social context to normalise nature engagement, The Wildlife Trusts developed a mass engagement campaign, 30 Days Wild. The campaign asked people to engage with nature every day for a month. 12,400 people signed up for 30 Days Wild via an online sign-up with an estimated 18,500 taking part overall, resulting in an estimated 300,000 engagements with nature by participants. Samples of those taking part were found to have sustained increases in happiness, health, connection to nature and pro-nature behaviours. With the improvement in health being predicted by the improvement in happiness, this relationship was mediated by the change in connection to nature.     

Farm animal embryo technologies: achievements and perspectives

Progress and changes in embryo technology in farm animals are briefly reviewed in terms of how well embryos can be made and used and what the subject has taught us about the maintenance of pregnancy and reproduction in general. Generalizations are made about the need to not accept dogma, how initially complex techniques always become simplified and thereby more applicable, and the need for the support of long-term and basic research. Personal views are offered on how best to prepare and motivate the next generation of scientists in the field, and the need for scientists to engage in the debate of how embryo technologies should be used responsibly in countering global inequalities.     

The factors influencing transactional sex among young men and women in 12 sub‐Saharan African countries

Abstract

Transactional sex may put young women and young men in sub‐Saharan Africa at increased risk of contracting sexually transmitted infections (STIs), including HIV/AIDS. This behavior may also put young women at higher risk of pregnancy and childbearing. Policymakers and program managers need to know what factors put youth at increased risk. We investigated this issue using logistic regression analyses of data from male and female modules of Demographic and Health Surveys from 12 sub‐Saharar African countries. We found that young men and young women are at greater risk of engaging in transactional sex than are older people. Unmarried young women and young men were significantly more likely to engage in transactional sex than married youth. Based on these results, our conclusions were that programs geared toward reducing the incidence of transactional sex or protecting men and women already in transactional sexual relationships should be aimed at both young women and young men. Due to our finding that unmarried young women and young men are more vulnerable to experiencing transactional sex, programs to prevent transactional sex should be specifically directed to this subgroup of young people.

Gestation as mothering

Some commentators maintain that gestational surrogates are not ‘mothers’ in a way capable of grounding a claim to motherhood. These commentators find that the practices that constitute motherhood do not extend to gestational surrogates. We argue that gestational surrogates should be construed as mothers of the children they bear, even if they fully intend to surrender those children at birth to the care of others. These women stand in a certain relationship to the expected children: they live in changed moral circumstances by reason of their pregnancy, and they engage in the practices said to define motherhood in the post-birth context. By contrast, ovum donors and embryo donors are not similarly ‘mothers’ because they do not find themselves involved in these circumstances. Not all women involved in three-parent in vitro fertilization qualify as mothers either. Given this analysis of mothering, we note that transmen who gestate children are engaged in mothering activity even if they otherwise function as a father to those children. By itself, this defence of the maternity of gestational surrogates does not confer moral title to the children they bear; gestation would not by itself override the contractual arrangements gestational surrogates have made regarding the disposition of their children. This interpretation of gestational surrogates as mothers does, however, undercut cultural understandings of these women as mere ‘vessels’, devoid of entitlement to respect as persons and parents. We also consider the meaning of mothering for ‘brain-dead’ women kept alive to give birth and for the prospect of extracorporeal gestation.     

Factors Influencing Owner Satisfaction With Companion-Dog-Training Facilities

The aim of this study was to survey people currently attending companion-dog-training facilities about their reasons for attending training, their expectations prior to training, their training experiences, and the factors contributing to their satisfaction with these experiences. The 178 participants indicated that they experienced few canine behavioral difficulties prior to attending training, with factors other than dog behavior influencing their decision to attend a particular facility. Features identified as important were characteristics of the instructors and the facility itself, opportunities for the dog caretaker (owner) to develop dog-training skills and knowledge, and specific canine behavior outcomes. Satisfaction was a multidimensional concept: satisfaction with the instructors and facility being dissociable from satisfaction with progress made by the dog and handler. Each of these represented different aspects of the training experience. Training facilities may need to address a wide range of issues to engage additional dog owners in training activities. Identification of these issues is an important first step in this process.

Viewing Time Measures of Sexual Orientation in Samoan Cisgender Men Who Engage in Sexual Interactions with Fa’afafine

Androphilia refers to attraction to adult males, whereas gynephilia refers to attraction to adult females. The current study employed self-report and viewing time (response time latency) measures of sexual attraction to determine the sexual orientation of Samoan cisgender men (i.e., males whose gender presentation and identity is concordant with their biological sex) who engage in sexual interactions with transgender male androphiles (known locally as fa’afafine) compared to: (1) Samoan cisgender men who only engage in sexual interactions with women, and (2) fa’afafine. As expected, both measures indicated that cisgender men who only engaged in sexual interactions with women exhibited a gynephilic pattern of sexual attraction, whereas fa’afafine exhibited an androphilic one. In contrast, both measures indicated that cisgender men who engaged in sexual interactions with fa’afafine demonstrated a bisexual pattern of sexual attraction. Most of the cisgender men who exhibited bisexual viewing times did not engage in sexual activity with both men and women indicating that the manner in which bisexual patterns of sexual attraction manifest behaviorally vary from one culture to the next.     

Gas Law for the Classroom

The author provides information on how science teachers can write science literacy objectives that help English language learners (ELLs) develop the scientific literacy needed for academic success in the science classroom. The article offers suggestions on how teachers can determine the vocabulary, language functions, and sentence structures that their students need to engage in critical thinking in science. An approach for collaboration with students' English as a second language (ESL) teacher is discussed.     

Animal tool-use

The sight of an animal making and using a tool captivates scientists and laymen alike, perhaps because it forces us to question some of our ideas about human uniqueness. Does the animal know how the tool works? Did it anticipate the need for the tool and make it in advance? To some, this fascination with tools seems arbitrary and anthropocentric; after all, animals engage in many other complex activities, like nest building, and we know that complex behaviour need not be cognitively demanding. But tool-using behaviour can also provide a powerful window into the minds of living animals, and help us to learn what capacities we share with them - and what might have changed to allow for the incontrovertibly unique levels of technology shown by modern humans.     

Black spaces,black places: Strategic assimilation and identity construction in middle-class suburbia

While white ethnics and immigrants of colour have been studied in terms of their attempts to assimilate into the American mainstream, sociologists assume that ongoing racial discrimination obviates the need for an extensive examination of the actual assimilation trajectories of middle-class blacks. Many middle-class blacks travel from the black to the white world rather than existing exclusively in one racially distinct environment. Yet, we do not fully understand how middle-class blacks conceptualize their own integration into American society. Drawing on data collected through in-depth interviews with middle-class blacks and ethnographic research in a white and a black suburb, I establish the link between an affinity for black spaces and the alternative assimilation trajectories of middle-class blacks. I find that middle-class blacks engage in a variant of segmented assimilation, privileging the black world as a site for socializing even if they live in a white suburb. This selective pattern of assimilation, what I term strategic assimilation, suggests that this population of middle-class blacks does not perceive itself as permanently constrained to the bottom rung of a racial hierarchy.     

An inexpensive gel electrophoresis-based polymerase chain reaction method for quantifying mRNA levels

In order to engage their students in a core methodology of the new genomics era, an ever-increasing number of faculty at primarily undergraduate institutions are gaining access to microarray technology. Their students are conducting successful microarray experiments designed to address a variety of interesting questions. A next step in these teaching and research laboratory projects is often validation of the microarray data for individual selected genes. In the research community, this usually involves the use of real-time polymerase chain reaction (PCR), a technology that requires instrumentation and reagents that are prohibitively expensive for most undergraduate institutions. The results of a survey of faculty teaching undergraduates in classroom and research settings indicate a clear need for an alternative approach. We sought to develop an inexpensive and student-friendly gel electrophoresis-based PCR method for quantifying messenger RNA (mRNA) levels using undergraduate researchers as models for students in teaching and research laboratories. We compared the results for three selected genes measured by microarray analysis, real-time PCR, and the gel electrophoresis-based method. The data support the use of the gel electrophoresis-based method as an inexpensive, convenient, yet reliable alternative for quantifying mRNA levels in undergraduate laboratories.     

The origins of belonging: social motivation in infants and young children

Our reliance on our group members has exerted a profound influence over our motivation: successful group functioning requires that we are motivated to interact, and engage, with those around us. In other words, we need to belong. In this article, I explore the developmental origins of our need to belong. I discuss existing evidence that, from early in development, children seek to affiliate with others and to form long-lasting bonds with their group members. Furthermore, when children are deprived of a sense of belonging, it has negative consequences for their well-being. This focus on social motivation enables us to examine why and in what circumstances children engage in particular behaviours. It thus provides an important complement to research on social cognition. In doing so, it opens up important questions for future research and provides a much-needed bridge between developmental and social psychology.     

An integrated view of aromatase and its inhibition

Aromatase inhibition has become a major treatment strategy for postmenopausal women with oestrogen-dependent breast cancer. Its optimal application is, however, dependent upon (i) the accurate identification of cancers which are ultimately dependent upon the activity of the aromatase enzyme, (ii) the use of the best method/inhibitor by which to blockade aromatase activity.

The single best predictor of response to aromatase inhibitors is the presence of tumour oestrogen receptors; receptor-negative cancers rarely respond whereas those with high levels seem particularly likely to benefit. However, there is a need for additional discriminatory markers. The use of microarray technology coupled with neoadjuvant therapy is likely to yield promising candidate genes. The finding that, amongst peripheral tissues, the tumour itself may have high activity has led to the suggestion that the tumour aromatase measurements may be predictive; however, in situ studies and the lack of robust assays for tumour aromatase suggest that tumour aromatase may not be an influential marker.

Whilst drugs such as anastrozole, exemestane, formestane and letrozole are all effective and specific inhibitors of aromatase, they differ in structure, potency and mechanism of action. Thus, differential sensitivity of tissues/tumours and non-cross resistance mean inhibitors are not equivalent and individual agents may have differing roles according to the setting in which they will be used. Aromatase inhibitors have evolved as key endocrine agents in the treatment of breast cancer. They offer the promise of rational treatment management based on the accurate identification of individual cohorts of tumours responsive to specific drugs.     

Live Imaging of Influenza Infection of the Trachea Reveals Dynamic Regulation of CD8+ T Cell Motility by Antigen

During a primary influenza infection, cytotoxic CD8+ T cells need to infiltrate the infected airways and engage virus-infected epithelial cells. The factors that regulate T cell motility in the infected airway tissue are not well known. To more precisely study T cell infiltration of the airways, we developed an experimental model system using the trachea as a site where live imaging can be performed. CD8+ T cell motility was dynamic with marked changes in motility on different days of the infection. In particular, significant changes in average cell velocity and confinement were evident on days 8–10 during which the T cells abruptly but transiently increase velocity on day 9. Experiments to distinguish whether infection itself or antigen affect motility revealed that it is antigen, not active infection per se that likely affects these changes as blockade of peptide/MHC resulted in increased velocity. These observations demonstrate that influenza tracheitis provides a robust experimental foundation to study molecular regulation of T cell motility during acute virus infection.     

Focus: Sex and Gender Health: Beyond the Pap Smear: Gender-responsive HIV Care for Women

Women comprise nearly one-quarter of all people living with human immunodeficiency virus (HIV) in the U.S. and 20 percent of incident annual cases. Though women overall are more likely than men to be diagnosed with HIV and engage in care, they are as unlikely to successfully achieve viral suppression with antiretroviral therapy, suggesting gender-based disparities that should be addressed by gender-responsive policies and programs. Using the socioecological model of health and syndemics theory, we comprehensively reviewed published literature to evaluate reasons for and ways to address gender differences in HIV risk and treatment. We discuss the biologic, sociocultural, interpersonal, and behavioral contexts of HIV risk that affect women, comprehensive healthcare for women with HIV that includes pregnancy planning or prevention, and policy implications.     

Gender Differences in Body Satisfaction

PINGITORE, REGINA, BONNIE SPRING, DAVID GARFIELD. Gender differences in body satisfaction. Although men and women show similar rates of obesity, women more frequently engage in weight loss efforts, with potentially adverse health consequences. We surveyed 320 college-aged men and women to examine gender differences in the determinants of body dissatisfaction and the degree of importance assigned to body-weight and shape. Results indicated that, for both genders, satisfaction with bodyweight and shape decreased as body mass index (BMI) increased. Women, however, showed significantly greater body and weight dissatisfaction than men at most weight categories. Only the underweight (BMI<20) women and men were similarly satisfied with their bodyweight and shape. As BMI increased, however, women became disproportionately more dissatisfied: both normal-weight and overweight women expressed greater dissatisfaction than comparable men. College-aged women also attributed progressively more importance to both weight and shape as BMI increased, unlike college-aged men, who considered body weight equally important to (or slightly less important than) self-esteem as BMI increased. We discuss implications for the self-esteem of obese women and men.     

"She drank his money": survival sex and the problem of violence in taverns in Gauteng province,South Africa

This article examines the practice of "survival sex" in the taverns of Soweto and Hammanskraal area, South Africa. Women who engage in survival sex do not self-identify as commercial sex workers, and the community does not identify them as such. Those who structure HIV prevention programs should not confound such women with commercial sex workers, because effective intervention may vary between the two groups. Violence against women who engage in survival sex in taverns is common, as it is argued that, when a woman accepts beer from a man, she is obliged to exchange sex (because she has "drunk his money"). The South African government should prioritize the reduction of violence as a way to reduce HIV transmission, as, in the context of violence, women do not have the option of negotiating safer sex.
