Preschool Children’s Behavioral Tendency toward Social Indirect Reciprocity

Social indirect reciprocity seems to be crucial in enabling large-scale cooperative networks among genetically unrelated individuals in humans. However, there are relatively few studies on social indirect reciprocity in children compared to adults. Investigating whether young children have a behavioral tendency toward social indirect reciprocity will help us understand how and when the fundamental ability to form cooperative relationships among adults is acquired. Using naturalistic observation at a nursery school, this study examined whether 5- to 6-year-olds show a behavioral tendency to engage in social indirect reciprocity in response to their peers’ prosocial behavior toward a third party. The results revealed that bystander children tended to display prosocial behavior toward their peers more frequently after observing these peers’ prosocial behavior toward third-party peers, compared with control situations; this suggests that 5- to 6-year-olds may have an essential behavioral tendency to establish social indirect reciprocity when interacting with peers in their daily lives. In addition, bystanders tended to display affiliative behavior after observing focal children’s prosocial behavior. In other words, observing peers’ prosocial behavior toward third-party peers evoked bystanders’ positive emotions toward the helpers. Considering both the present results and previous findings, we speculate that in preschoolers, such positive emotions might mediate the increase in the bystander’s prosocial behavior toward the helper. In addition, an intuitional emotional process plays an important role in the preschooler’s behavioral tendency toward social indirect reciprocity in natural interactions with peers.     

Carob or St. John’s Bread

Carob is the large bean-like pod of a handsome evergreen tree of the same name. Containing 40% sugar and 6% protein, it is chiefly used for stock food and is manufactured into various forms of human food. From the seeds comes a valuable gum, in increasing demand in commerce. Carob trees thrive in parts of California without irrigation.     

Instructional Integration of Disciplines for Promoting Children’s Positive Attitudes Towards Plants

Plants are an integral part of nature. Many plant species in almost any part of the world are under serious threats due to various reasons such as deforestation, pollution–of air, water and soil–caused by industrialisation, overgrazing and rapid population growth. It is likely that people have strong positive attitudes towards conservation of plants. This study investigated the effectiveness of an instructional approach based on integration of botany with chemistry and art on students’ attitude towards plants. This study was carried out in a science summer school for 10–12-years-old students (N = 49) in Turkey. The Plant Attitude Questionnaire was used as pre-test and post-test to assess the effects of the instruction on the students’ attitudes towards plants. Moreover, the participating children were asked to keep journals throughout the instruction. The children’s journals served as a data collection tool. The findings of the study indicated that integration of botany with chemistry and art is a good way to support children’s positive attitudes towards plants, particularly for an instructional approach based on the integration of plants with various disciplines to support children’s interest and enjoyment of plants. Also, this approach could offer children opportunities to understand the importance of plants in the living environments of humans and other organisms, and material benefits from plants in industry.     

Mesophotic reef fish assemblages of the remote St. Peter and St. Paul’s Archipelago,Mid-Atlantic Ridge,Brazil

Mesophotic reef fish assemblages (30–90 m depth) of the small and remote St. Peter and St. Paul’s Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil, were characterized using remotely operated vehicles. Ordination analyses identified distinct fish assemblages in the upper (30–50 m) and lower (50–90 m) mesophotic zones, the former characterized by high abundances of species that are also abundant at euphotic reefs (Caranx lugubris, Melichthys niger, Stegastes sanctipauli and Chromis multilineata) and the latter dominated by two mesophotic specialists (Prognathodes obliquus and Chromis enchrysura). Planktivores dominated fish assemblages, particularly in the upper mesophotic zone, possibly due to a greater availability of zooplankton coming from the colder Equatorial Undercurrent in mesophotic depths of the SPSPA. Turf algae, fleshy macroalgae and scleractinian corals dominated benthic assemblages between 30 and 40 m depth, while bryozoans, black corals and sponges dominated between 40 and 90 m depth. Canonical correspondence analysis explained 74 % of the relationship between environmental characteristics (depth, benthic cover and complexity) and structure of fish assemblages, with depth as the most important independent variable. Juveniles of Bodianus insularis and adults of P. obliquus and C. enchrysura were clearly associated with branching black corals (Tanacetipathes spp.), suggesting that black corals play key ecological roles in lower mesophotic reefs of the SPSPA. Results from this study add to the global database about mesophotic reef ecosystems (MREs) and provide a baseline for future evaluations of possible anthropogenic and natural disturbances on MREs of the SPSPA.     

Ethnoprimatology without Conservation: The Political Ecology of Farmer–Green Monkey (<Emphasis Type="Italic">Chlorocebus sabaeus</Emphasis>) Relations in St. Kitts,West Indies

The driving force behind the mixed-methods ethnoprimatological endeavor is to effectively conserve nonhuman primates. In this article, I argue that ethnoprimatological research can meet this goal only by discarding the purely science views of conservation that dominate the current literature. By considering more than local ecological perceptions, their ideological agendas, and their levels of power via a political ecology framework, ethnoprimatologists can simultaneously socialize the ecosystems we study and contribute our ethological skills to advance traditionally humanist disciplines’ increased attention to a wider field of agents and structures that matter. I support these arguments through an examination of farmer–green monkey (Chlorocebus sabaeus) relations in St. Kitts. Kittitian farmers’ narrative revealed three scales that collectively construct what is locally known as “the monkey problem:” increased rates of local contact between farmers and monkeys on farms, contestations over the future of St. Kitts’ land, and global debates over appropriate strategies to manage the monkey population. I show that although “the monkey problem” in St. Kitts does not involve an endangered or threatened species, my analysis of this construct has implications for primate populations that are threatened. This is because the root cause of this “problem”—the globalized discourse of nature conservation overpowering and problematizing local views about people–animal interactions—characterizes so many of the locales home to primates of conservation concern.

Influence of nitrogen on the production of hypericins by St. John’s wort

The effect of nitrogen supply on the production of ‘hypericins’ (hypericin and pseudohypericin) in leaves of St. John’s wort (Hypericum perforatum L.) was examined with plants grown in sand culture and soil. In sand culture, 56-d growth of St. John’s wort plants with decreased nitrogen levels resulted in increased production of hypericins in leaves. A short-term low nitrogen stress in sand culture also resulted in increased production of leaf hypericins. While growth in a low nitrogen-containing soil resulted in elevated levels of hypericins, their production was decreased by supplementation of the soil with additional nitrogen. Increased production of hypericins in St. John’s wort leaves did not require the nitrogen supply to be decreased to levels that resulted in nitrogen deficiency symptoms. Moreover, alteration in the production of leaf hypericins occurring with changes in nitrogen supply did not alter the concentration ratio of pseudohypericin and hypericin. Increased production of leaf hypericins was not associated with any significant changes in the number of dark glands on the leaves and only a weak correlation was observed between leaf dark gland number and levels of leaf hypericins. These results are discussed in terms of the biochemistry of naphthodianthrone production by St. John’s wort plants and implications for growth environment effects during cultivated growth of this medicinal plant.     

Indo-Fijian Children’s BMI

Health research has shown that overweight and obesity in children and adults are becoming significant public health problems in the developing world. Evidence suggests that this phenomenon is more marked in urban than rural areas and may be associated with modernization. However, the underlying reasons for this nutrition transition remain unclear. Dietary shifts, often in conjunction with income and time constraints in urban environments, may entail a greater reliance on more convenient sugar and fat-dense food. Also, the necessity of labor-intensive agricultural work to meet rural subsistence needs is supplanted in urban environments by sedentary work. This paper extends the application of human behavioral ecology theory into the realm of international development and policy by applying Kaplan’s embodied capital theory to explore differences in food habits and nutritional status of Indo-Fijian children within the context of urbanization. Urban high-embodied-capital women demonstrate higher rates of wage-earning employment than urban low-embodied-capital or rural women. Findings indicate that urban high-embodied-capital households spend significantly more on food purchases, purchase a greater proportion of processed foods, and have children with higher body mass indexes (BMI) than do urban low-embodied-capital or rural households. This suggests that urban high-embodied-capital mothers, who tend to be employed, may be making trade-offs between income and food choices.

Saudis’ Attitudes toward Chemical Pollution of the Environment,Al-Baha Region,Saudi Arabia

The results of a public opinion survey were used to assess the variation in attitudes toward the chemical pollution of the environment among Saudi residents of the Al-Baha region, Saudi Arabia. A total of 17 statements were given to respondents, addressing general opinions about health risks from chemical pollution. The main findings of this study are: (1) Most Saudis consider the place where they live unhealthful; (2) there was substantial concern about exposure to chemicals with more than 77% of respondents indicating a conscious effort to avoid chemicals in their daily life; (3) chemicals were seen as predominantly being “dangerous” and leading to more harm than good, and they see that the more a person is exposed to chemicals causing cancer the more likely he/she will get cancer; (4) Respondents see that chemicals in the environment are less harmful than chemicals from lifestyle factors and they disagree with the statement that “use of chemicals has improved their health more than it has harmed them”; (5) Saudis are not prepared to accept some health risks in order to benefit the economy. The study did not find any potential relationship between gender, age range, place of residence, and education level and attitude toward chemical pollution among Saudi residents.     

Medical Students’ Attitudes toward Abortion Education: Malaysian Perspective

Background

Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students’ attitudes toward abortion education and presents a case for including abortion education in medical schools.

Methods and Results

A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students’ pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students’ attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity.

Conclusions

Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights.     

Exploring Children’s Perspectives on the Welfare Needs of Pet Animals

Children are increasingly viewed as important recipients of educational interventions to improve animal welfare, yet research examining their perspectives is lacking, particularly within the UK. Helping children to care appropriately for animals depends, not least, on an ability to understand the needs of different species and correctly identify cues given by the animal that indicate its welfare state. This study began to explore: (a) children’s perceptions of welfare needs, focusing on four common pet animals; (b) influences on the development of knowledge; (c) beliefs about whether or not (all) animals are sentient, and (d) their confidence in identifying when their own pets are in need. Fourteen focus groups were carried out with 53 children aged 7 to 13 years. Findings highlighted an affirmative response that animals have feelings (dogs especially), albeit with doubts about this applying universally. There was wide variation in children’s knowledge of welfare needs, even among owners of the animal in question. Conversely, some children lacked confidence in spite of the extensive knowledge they had developed through direct experience. An important finding was a perceived difficulty in identifying the needs of particular species or specific types of need in their own pets. Fitting well with a recent emphasis on “positive welfare,” children felt that many animals need demonstrative love and attention, especially cats and dogs. While there is clearly scope for educating children about common needs and cues that indicate animals’ welfare state, other areas pose a greater challenge. Emotional connection seems important in the development of extensive knowledge and concern for welfare. Accordingly, animals that do not possess the kind of behavioral repertoire that is easy to interpret or allows for a perceived sense of reciprocity are possibly at risk of negative welfare experiences.     

Pauli Murray’s journey toward social justice

Pauli Murray’s lifelong fate was to be both ahead of her times concerning racism, heteropatriarchy, and class exploitation, yet largely behind the scenes within social movements that challenged these systems of oppression. As a truly independent African American feminist thinker, Murray’s accomplishments have long remained relatively unknown. This review essay analyses The Firebrand and the Lady and Jane Crow, two important biographies that constitute important additions to the growing corpus of scholarship on Murray’s life. These books lay a scholarly foundation for studying not only the life of this neglected African American feminist intellectual activist, but also how her ideas and actions catalyzed social change. Drawing upon contemporary anti-racist, feminist and intersectional frameworks, this essay analyses how both books draw upon race, class, gender, and sexuality as categories of analysis, yet place different analytical weight on these concepts.     

Adolescents’ Experience and Knowledge of,and Attitudes toward,Bees: Implications and Recommendations for Conservation

Invertebrates are generally regarded with apathy, distaste, and fear in Western society. These negative sentiments likely contribute to the disparity in wildlife conservation efforts, which largely favor vertebrate organisms. Bees represent one of the most ecologically and economically important invertebrate groups, yet bee diversity and abundance is declining worldwide, mirroring the general decline of invertebrate biodiversity. Developing and implementing successful conservation efforts requires interdisciplinary research that considers the ecological and social realities of today’s world. To better inform conservation efforts related to bees, we examined adolescents’ experiences and knowledge of, and attitudes toward, bees and investigated how these dimensions related to one another. A total of 794 eighth-grade science students from the suburbs of Chicago, USA completed a 48-item, paper questionnaire. The results indicated that adolescents were only somewhat knowledgeable about bee biology and services, and they confused bees with other flying insects, especially those with black-and-yellow coloration. Adolescents regarded bees with a generally neutral attitude; their knowledge and attitudes were correlated in a positive manner. Various bee-related experiences were linked to adolescents’ knowledge and attitudes and may have influenced bee-related behavior. In particular, students who engaged in gardening and lawn-care activities demonstrated higher levels of knowledge and more positive attitudes. This study provides insight into the relationships between experiences and knowledge of, and attitudes toward, invertebrates and suggests that engaging in certain outdoor activities may promote positive attitudes toward bees among adolescents.     

A Survey of Veterinarians’ Attitudes toward Euthanasia of Companion Animals in Japan

This study investigated veterinarians’ attitudes toward euthanasia of companion animals in Japan. A nationwide survey was conducted with 932 veterinarians in small animal practices. It examined the number of times they administered euthanasia, their moral criteria for choosing euthanasia for animals, and their behavioral criteria for suggesting euthanasia to owners. According to the data analyses, on average the veterinarians administered euthanasia 2.48 times a year. For many veterinarians, two conditions were necessary to justify euthanasia for animals: “the animals are incurable and suffering” and “the owners request to euthanize the animals.” In the absence of either condition, the veterinarians were inclined to disapprove of choosing euthanasia. If the owners requested further treatment, 67% showed clear disapproval of choosing euthanasia for animals with serious medical conditions. Meanwhile, more than 76% showed clear disapproval of euthanizing healthy animals when the owners requested it. These results indicate that the owners’ request takes precedence over the animals’ condition for suffering animals, but not for healthy animals. For animals with serious medical conditions, 56% of the veterinarians answered that they would or might suggest euthanasia to the owners even though the owners requested further treatment. In this situation, for some veterinarians, the animals’ condition rather than the owners’ request might become a determinant in suggesting euthanasia to owners, even if their moral judgments were against choosing euthanasia for the animals. A decrease in the owners’ or the animals’ quality of life and the owners’ inability to pay were not primary factors in choosing or suggesting euthanasia. Having an experience of euthanizing their own animals was a key factor for the veterinarians which increased not only the number of times they administered euthanasia but also the degree of their moral approval of choosing euthanasia and their behavioral willingness to suggest it to owners.     

Effect of Women’s Perceptions and Household Practices on Children’s Waterborne Illness in a Low Income Community

An ecosystem approach to human health was adopted in a community-based study carried out in Bebnine, an underserved town in Lebanon. The objective of the study is to examine the association between women’s household practices and diarrhea among children in a setting where contaminated drinking water and intestinal diseases are common. A total of 280 women were randomly selected and interviewed using a structured questionnaire. Data were collected on 712 children between the ages of 6 and 14. The study instrument included determinants of diarrhea such as sociodemographic characteristics, water, sanitation, hygiene practices, gender variables, and behavioral risk factors. Multivariate regression analysis was employed to examine the association between water handling practices and diarrhea. The prevalence of diarrhea is 5%. Female children are more likely to suffer from diarrhea than male children (OR = 2.58; 95% CI: 1.19–5.62). Treatment of drinking water at the household level and the use of drinking water for cooking and the preparation of hot beverages are protective against diarrhea (OR = 0.15; 95% CI: 0.03–0.65). Female caretakers’ behaviors such as daily bathing and seeking medical care at times of illness are protective against diarrhea in children. The findings suggest that diarrhea is a gendered health problem. Female children, who are generally more involved in household activities than male children, are at higher risk of suffering from diarrhea. Female caretakers’ personal hygiene, household practices, and perceptions of diarrhea are additional risk factors. Intervention activities would be more effective if based on a better understanding of gender roles and household power relations.
