Analysis of Pelvis-Thorax Coordination Patterns of Professional and Amateur Golfers during Golf Swing

The aim of this research was to quantify the coordination pattern between thorax and pelvis during a golf swing. The coordination patterns were calculated using vector coding technique, which had been applied to quantify the coordination changes in coupling angle (γ) between two different segments. For this, fifteen professional and fifteen amateur golfers who had no significant history of musculoskeletal injuries. There was no significant difference in coordination patterns between the two groups for rotation motion during backswing (p = 0.333). On the other hand, during the downswing phase, there were significant differences between professional and amateur groups in all motions (flexion/extension: professional [γ] = 187.8°, amateur [γ] = 167.4°; side bending: professional [γ] = 288.4°, amateur [γ] = 245.7°; rotation: professional [γ] = 232.0°, amateur [γ] = 229.5°). These results are expected to be a discriminating measure to assess complex coordination of golfers' trunk movements and preliminary study for interesting comparison by golf skilled levels.     

Two-Way Regularized Fuzzy Clustering of Multiple Correspondence Analysis

Multiple correspondence analysis (MCA) is a useful tool for investigating the interrelationships among dummy-coded categorical variables. MCA has been combined with clustering methods to examine whether there exist heterogeneous subclusters of a population, which exhibit cluster-level heterogeneity. These combined approaches aim to classify either observations only (one-way clustering of MCA) or both observations and variable categories (two-way clustering of MCA). The latter approach is favored because its solutions are easier to interpret by providing explicitly which subgroup of observations is associated with which subset of variable categories. Nonetheless, the two-way approach has been built on hard classification that assumes observations and/or variable categories to belong to only one cluster. To relax this assumption, we propose two-way fuzzy clustering of MCA. Specifically, we combine MCA with fuzzy k-means simultaneously to classify a subgroup of observations and a subset of variable categories into a common cluster, while allowing both observations and variable categories to belong partially to multiple clusters. Importantly, we adopt regularized fuzzy k-means, thereby enabling us to decide the degree of fuzziness in cluster memberships automatically. We evaluate the performance of the proposed approach through the analysis of simulated and real data, in comparison with existing two-way clustering approaches.     

Magic Learning Pill: Ontological and Instrumental Learning in Order to Speed Up Education

The purpose of this research is to investigate the phenomenology of learning — people”s attitudes toward their learning experiences that have inherent worth in themselves (i.e., ontological learning) or have value outside of the learning itself (i.e., instrumental learning). In order to explore this topic, 58 participants from the U.S., Russia, and Brazil were interviewed with a central question derived from the science fiction writer Isaac Asimov’s short story “Profession”: whether participants would take a “Magic Learning Pill” (MLP) to avoid the process of learning, and instead magically acquire the knowledge. The MLP would guarantee the immediate learning by skipping the process of learning while achieving the same effect of gaining skills and knowledge. Almost all participants could think of some learning experiences for which they would take MLP and others for which they would not. Many participants would not take MLP for ontological learning, which is learning experiences that have inherent value for the people, while they would take MLP for instrumental learning, which is learning that mainly serves some other non-educational purposes. The main finding suggests that both instrumental and ontological types of learning are recognized by a wide range of people from diverse cultures as present and valued in their lives. This is especially significant in light of the overwhelmingly instrumental tone of public discourse about education. In the context of formal education, ontological learning was mentioned 35 times (28.0%) while instrumental learning was mentioned 74 times (60.2%). Although ontological learning was often mentioned as taking place outside of school, incorporating pedagogy supporting ontological learning at school deserves consideration.     

Influences of stereotype and social distance on prejudice toward African Americans

The study sought to identify the influential factors of stereotypes, social distance, and prejudice toward racial/ethnic minorities in the United States. We used data from the American General Social Survey (GSS) of 2012, and analysed the data of 4 820 individuals (3 700 Caucasians, 722 African Americans, and 398 others; males?=?44.2%, females?=?55.8%). Data were analysed using the SPSS 18.0 Statistics Program. In order to test for differences in racial prejudice by demographic characteristics by stereotyping and social distancing, we utilised variance and regression analyses procedures. Results suggest that stereotypes and social distance effects on prejudice toward African Americans vary according to ethnicity, gender, age, education, and income. Specifically, older and less-educated white males were more prejudiced toward African Americans than were individuals from other sociodemographic groupings. There was a direct relationship between the holding of stereotypical views and social distance, in that those who showed higher levels of stereotyping maintained a greater social distance from African Americans and showed greater implicit prejudice toward them. Racism toward African Americans remains a major social concern in the USA, and is largely influenced by sociodemographic factors.     

Further examination of the Self-efficacy Scale

The purpose of this study was to examine further the factorial validity of the Self-efficacy Scale via component and subsequent correlational analyses. 651 undergraduates enrolled in an introductory psychology course voluntarily completed the Self-efficacy Scale and the Bem Sex-role Inventory. A principal component analysis with an orthogonal rotation produced a two-factor solution which was remarkably similar to the factor structures reported previously. The two factors (General Self-efficacy and Social Self-efficacy) accounted for about 34% of the total variance. Further, the correlation coefficients indicated that General Self-efficacy was more strongly related to masculine traits than to feminine traits, as defined by the Bem Sex-role Inventory.     

How health motivation moderates the effect of vividness on consumption expectations of indulgent food

The current research examines how the vividness of food depictions affects consumers' consumption expectations of indulgent food items. Through three studies, we found that the level of motivation to be healthy plays a crucial role in determining how vividness impacts their consumption expectations of indulgent food items. Specifically, when consumers are less motivated to be healthy, vividness increases their consumption expectations due to increased attention-driven involvement with the food information. On the other hand, when consumers are motivated to be healthy, vividness is assumed to increase goal conflict, leading to reduced consumption expectations. Importantly, our research also found that the joint effect of vividness and health motivations on consumption expectations is attenuated when the indulgent food items contain healthy ingredients.     

The COVID-19 threat and luxury advertising

The purpose of this research is to examine how the COVID-19 pandemic has impacted the luxury goods industry. The authors hypothesize that pandemic threats drive consumers toward luxury consumption to increase their perceptions of control. The article reports results of three experimental studies conducted in the United States. In Study 1, after participants read an article about COVID-19, they respond favorably to an advertisement for a luxury brand. The comparative control participants read an article about a tofu dish and respond less favorably to the luxury advertisement. Study 2 provides further evidence that perceived control acts as a mediator, while ruling out alternative explanations. Study 3 indicates that threat evokes luxury preferences only when advertisements for both luxury and nonluxury products use abstract messages, as opposed to concrete messages. The findings provide practical insights showing that the most effective advertising strategy for luxury brand managers is to use abstract rather than concrete messages for targeting consumers who feel highly threatened by COVID-19.     

Cyberostracism: effects of being ignored over the Internet

Ostracism is such a widely used and powerful tactic that the authors tested whether people would be affected by it even under remote and artificial circumstances. In Study 1, 1,486 participants from 62 countries accessed the authors' on-line experiment on the Internet. They were asked to use mental visualization while playing a virtual tossing game with two others (who were actually computer generated and controlled). Despite the minimal nature of their experience, the more participants were ostracized, the more they reported feeling bad, having less control, and losing a sense of belonging. In Study 2, ostracized participants were more likely to conform on a subsequent task. The results are discussed in terms of supporting K. D. Williams's (1997) need threat theory of ostracism.     

Ecological Themes in Evangelii Gaudium,Together towards Life,and The Cape Town Commitment for Fraternity with God's Creation

The main purpose of this study is to explore the Christian response to the current ecological crisis by examining three statements using a method of theological reflection: Evangelii Gaudium (EG), Together towards Life (TTL), and The Cape Town Commitment (CTC). The three statements request Christians’ care for creation, which is now threatened. In contemplating the ecological crisis, the three statements call attention to the widespread abuse and destruction of the Earth due to an economic system that accelerates consumerism and human greed. To overcome this ecological crisis, Pope Francis recalls the joy of the gospel overflowing from the Trinity; TTL and CTC echo this, drawing their faith tradition from the Trinity with widening understanding of God who is creator, redeemer, and sustainer. The three statements also identify the rest of creation as the new poor in order to recall that the suffering of the poor and the suffering of the earth are one, inseparable from the suffering of Jesus. Finally, this study examines the three statements in relation to the spirituality of ecological themes. In particular, EG and TTL discern a false spirituality that is a form of individualism and a theology of prosperity, but suggest a spirituality that is referred to as either transformative spirituality or mystical fraternity. The study concludes that it is time to turn to the cosmological dimension of spirituality and theology for fraternity with God's creation and the future of the earth community.     

Subjective well-being,social buffering and hedonic editing in the quotidian

A previous study on the relationship between subjective well-being (SWB) and hedonic editing—the process of mentally integrating or segregating different events during decision-making—showed that happy individuals preferred the social-buffering strategy more than less happy individuals. The present study examined the relationship between SWB, social-buffering and hedonic outcomes in daily life. In Study 1, we used web-based diaries to measure the frequency with which individuals utilised social and non-social buffers as well as daily levels of happiness. Consistent with the previous finding, happy individuals utilised social buffers more frequently than less happy individuals. Interestingly, the utilisation of social buffers had a positive effect on daily happiness among all participants, regardless of individuals’ levels of SWB. In Study 2, we found that although the use of social buffers yielded similar effects across groups on online evaluations of events, happy individuals showed a positive bias in global evaluations of past events. This finding suggests that how one construes and remembers the outcomes of social buffering may shape the different hedonic editing preferences among happy and less happy individuals.
