Food Systems Change and the Environment: Local and Global Connections

Making changes to the way food is produced, distributed, and processed is one strategy for addressing global climate change. In this case study, we examine the "forming" stage of an emergent and locally-based coalition that is both participatory and focused on promoting food security by creating food systems change. Social network analysis is used to compare network density, centrality, and centralization among coalition partners before the formation of the coalition and at its one-year anniversary. Findings reveal that the coalition facilitated information seeking, assistance seeking, and collaborative efforts related to food security among a group of organizational stakeholders that were relatively disconnected pre-coalition. Results also illuminate tensions related to increased centralization of the network, coalition efficiency, and the goals of democratic decision-making. This study highlights the utility of social network analysis as a tool for evaluating the aims and trajectory of locally-based coalitions focused on global concerns.     

Mental abilities and school achievement: A test of a mediation hypothesis

This study analyzes the interplay of four cognitive abilities - reasoning, divergent thinking, mental speed, and short-term memory - and their impact on academic achievement in school in a sample of adolescents in grades seven to 10 (N = 1135). Based on information processing approaches to intelligence, we tested a mediation hypothesis, which states that the complex cognitive abilities of reasoning and divergent thinking mediate the influence of the basic cognitive abilities of mental speed and short-term memory on achievement. We administered a comprehensive test battery and analyzed the data through structural equation modeling while controlling for the cluster structure of the data. Our findings support the notion that mental speed and short-term memory, as ability factors reflecting basic cognitive processes, exert an indirect influence on academic achievement by affecting reasoning and divergent thinking (total indirect effects: β = .22 and .24, respectively). Short-term memory also directly affects achievement (β = .22).     

Digit ratio (2D:4D), academic performance in computer science and computer-related anxiety

Being able to use information communication technology (ICT) effectively has become an essential element of participation within an increasingly digital culture. However, there are differences in participation within this digital culture. Prenatal testosterone exposure is thought to influence the development of numeric capabilities and relate to levels of anxiety, both of which contribute towards engagement with ICT. This study examined whether an index of prenatal exposure to testosterone, digit ratio (2D:4D), is related to successful involvement within a computer-technology context - performance in a Java programming course. Three studies (N = 73,75,65) identified a consistent negative correlation between 2D:4D digit ratio and attainment (r ≈ −0.2). A fourth study (N = 119) found that 2D:4D digit ratio positively correlated with two indices of computer-related anxieties, as well as anxiety sensitivity (r = 0.32/0.51). These results suggest that males and females who have been exposed to higher levels of testosterone within the womb perform better upon academic assessments of Java-related programming ability within computer science education, and have lower levels of computer-related anxieties outside computer science education. Thus, the 2D:4D index of prenatal testosterone exposure correlated with the two factors that directly impact upon ICT engagement, which is increasingly essential to effectively participate within educational and occupational environments.     

The Big Five personality traits, learning styles, and academic achievement

Personality and learning styles are both likely to play significant roles in influencing academic achievement. College students (308 undergraduates) completed the Five Factor Inventory and the Inventory of Learning Processes and reported their grade point average. Two of the Big Five traits, conscientiousness and agreeableness, were positively related with all four learning styles (synthesis analysis, methodical study, fact retention, and elaborative processing), whereas neuroticism was negatively related with all four learning styles. In addition, extraversion and openness were positively related with elaborative processing. The Big Five together explained 14% of the variance in grade point average (GPA), and learning styles explained an additional 3%, suggesting that both personality traits and learning styles contribute to academic performance. Further, the relationship between openness and GPA was mediated by reflective learning styles (synthesis-analysis and elaborative processing). These latter results suggest that being intellectually curious fully enhances academic performance when students combine this scholarly interest with thoughtful information processing. Implications of these results are discussed in the context of teaching techniques and curriculum design.     

Relations from temperamental approach reactivity and effortful control to academic achievement and peer relations in early elementary school

The goal of the current study was to examine relations from temperamental approach reactivity (i.e., impulsivity, frustration, and positive affect) and effortful control (EC; 42 and 54 months) to teachers’ reports of academic achievement and popularity (72 and 84 months). Frustration was positively related to achievement and negatively related to popularity for girls, but unrelated to boys’ outcomes. Interactions suggested that, among children with high EC or emotional approach (frustration or positive emotion), impulsivity positively predicted achievement. Few gender differences in interactions were noted. These results provide insight into the dynamics relations from temperament/personality to children’s academic and social adjustment.     

Academic success in adolescence: Relationships among verbal IQ,social support and emotional intelligence

The objective of this study was to examine, by gender, whether emotional intelligence (EI), peer social support, and/or family social support partially mediated the influence of verbal IQ on Grade 10 grade point average (GPA) for 192 students (96 male, 96 female). For male students, EI and peer social support predicted GPA and EI mediated the association between verbal IQ and GPA. For female students, EI, peer social support, and family support predicted GPA but did not mediate the association between verbal IQ and GPA. This study further examined whether subscales of EI (intrapersonal, interpersonal, adaptability, and stress management abilities), peer social support and family social support (emotional, socialising, practical, financial, and advice) added to the prediction of GPA after verbal IQ, gender, and socioeconomic status were controlled. Adaptability, stress management and practical family social support each added to the explanation of variability. None of the peer social support subscales predicted additional variance in GPA.

竞争和合作对学龄前儿童分配模式的影响:心理理论和抑制控制的作用

研究考察在双方贡献不相等时,3~6岁儿童分配模式的发展趋势及其原因。98名儿童在竞争或合作情境下和玩偶进行钓鱼游戏,然后对6枚冰箱贴进行分配。结果发现5~6岁儿童比3~4岁儿童进行平均分配的比例更高,一级心理理论和抑制控制能力完全中介了年龄的效应。和竞争情境相比,合作情境促进儿童进行平均分配,同时情境调节了抑制控制对分配模式的影响。研究表明一级心理理论和抑制控制能力的发展能够解释学龄前儿童分配模式的变化。     

Don't cheat,be happy. Self‐control,self‐beliefs,and satisfaction with life in academic honesty: A cross‐sectional study in Poland

Academic dishonesty is dishonest behavior at school or university which is supposed to result in a passed exam or in a positive grade. Academic dishonesty is a global problem, present at every stage of education. Since the consequences of this phenomenon may be serious, such as a low level of knowledge despite receiving a diploma from a school or university or carrying dishonest behaviors over into other domains of functioning, research into this phenomenon also seems to be of high significance. Cheating, plagiarism, and falsification are the forms of academic of dishonesty. The aim of this study was to establish how academic dishonesty is related to self‐control, self‐beliefs, and satisfaction with life. The sample consisted of 631 participants, to whom we administered the Academic Honesty Scale, the Brief Self‐Control Scale, the Social Success Index, the Normalcy Feeling Scale, the Social Comparison Scale, and the Satisfaction With Life Scale. We found that academic dishonesty was linked with some of the variables. The results indicated that academic dishonesty and self‐control were negatively related to academic cheating and that social comparison was positively related to plagiarism and falsification. It also turned out that women scored lower than men on academic dishonesty. Research findings on academic dishonesty have a number of important implications for education, particularly for psychologists, teachers, and sociologists.
