The Interplay Between Personal Identity and Social Identity Among Vocational High School Students: A Three-Wave Longitudinal Study
Full text linkAlthough identity research has predominantly focused on college-bound adolescents, it has largely neglected vocational high school students who enter the job market immediately after graduation. Furthermore, most studies have concentrated on personal identity and have overlooked the concurrent development of social identity. This study examined the relationship between adolescents’ personal and social identities over three years of vocational high school. The participants were 4,264 vocational high school students in Japan (Time 1: 46.44% girls; Mage = 15.78). Using a random intercept cross-lagged panel model, the results indicated that within-person increases in social identity predicted increases in personal identity one year later. These findings highlight the importance of social identity as a valuable resource for personal identity development among vocational high school students, a group underrepresented in identity research
Diverse-and-Dynamic Pathways in Educational and Interpersonal Identity Formation during Adolescence: Longitudinal Links With Psychosocial Functioning
Full text linkThis study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted five identity trajectories in each educational and interpersonal identity domain and revealed (a) high prevalence of low commitment identity trajectories, (b) absence of the closure trajectory, and (c) changeable identity trajectories that have not been identified in Western context (i.e., the Netherlands). Furthermore, a latent change model revealed dynamic relations between identity trajectories and psychosocial functioning. These findings provide critical insights into the diverse and dynamic pathways of identity formation during adolescence in Japan
Role of the H+2 channel in the primordial star formation under strong radiation field and the critical intensity for the supermassive star formation
Full text linkWe investigate the role of the H+2 channel on H2 molecule formation during the collapse of primordial gas clouds immersed in strong radiation fields which are assumed to have the shape of a diluted blackbody spectra with temperature Trad. Since the photodissociation rate of H+2 depends on its level population, we take full account of the vibrationally resolved H+2 kinetics.We find that in clouds under soft but intense radiation fields with spectral temperature Trad ≲ 7000 K, the H+2 channel is the dominant H2 formation process. On the other hand, for harder spectra with Trad ≳ 7000 K, the H- channel takes over H+2 in the production of molecular hydrogen.We calculate the critical radiation intensity needed for supermassive star formation by direct collapse and examine its dependence on the H+2 level population. Under the assumption of local thermodynamic equilibrium (LTE) level population, the critical intensity is underestimated by a factor of a few for soft spectra with Trad ≲ 7000 K. For harder spectra, the value of the critical intensity is not affected by the level population of H+2 . This result justifies previous estimates of the critical intensity assuming LTE populations since radiation sources like young and/or metal-poor galaxies are predicted to have rather hard spectra
Direction of associations between personality traits and educational identity processes: Between‐ and within‐person associations
Full text linkIntroduction: In adolescence, personality traits and educational identity processes are interwoven. Previous studies have shown that personality traits predict healthy identity commitment and exploration in education. However, the direction of associations between personality traits and an identity process that searches for another identity option (i.e., reconsideration of commitment) is unclear. Furthermore, there is a lack of prospective studies regarding the direction of the association between personality traits and the educational identity process using within-person methods. Therefore, this study examined the direction of these associations. Methods: Participants of this four-wave longitudinal study comprised 618 Japanese 13-year-old adolescents (53.3% girls). This study involved a 1-year-interval assessment. Results: Cross-lagged panel models (CLPM) indicated that four personality traits (neuroticism, agreeableness, and conscientiousness) predicted three educational identity processes, while reconsideration of commitment predicted two personality traits (i.e., neuroticism and conscientiousness). Random intercept cross-lagged panel models (RI-CLPM) indicated that agreeableness predicted healthy commitment, while commitment predicted agreeableness at within-person level. Conclusion: The findings from CLPM suggest that reconsideration of commitment is a significant factor to predict healthy (i.e., conscientiousness) and unhealthy (i.e., neuroticism) personality traits in individual differences. Furthermore, the findings from RI-CLPM suggest that agreeableness may be a key trait in promoting healthy educational identity commitment. Theoretical and practical implications of these findings are discussed
Adolescents’ Identity Development Predicts the Transition and the Adjustment to Tertiary Education or Work
Full text linkAlthough identity development is crucial in individuals’ psychological adjustment from adolescence to adulthood, little is known about its impact in the transition to tertiary education or work. This study examined whether identity development during high school predicts career choices and adjustment (i.e., engagement) and maladjustment (i.e., burnout) after graduation. A total of 357 Japanese adolescents participated throughout the 3-year period of vocational high school (M age = 15.75; 62.75% girls). A follow-up assessment, at 18 months after the school-to-tertiary education or school-to-work transitions, was conducted. Higher identity synthesis during high school years predicted entry into tertiary education, while higher identity confusion predicted transition to work. Furthermore, higher identity synthesis during the high school years predicted higher post-graduation academic engagement, and higher levels of identity confusion predicted higher levels of post-graduation academic or work burnout. Overall, this study contributes to the understanding of the role of identity development in adolescence as a valuable asset for predicting the transition and the adjustment to tertiary education or work
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
