Personal Identity in College and the Work Context: Developmental Trajectories and Psychosocial Functioning

Personal identity formation represents a core developmental challenge for adolescents and young adults. Because much of the identity literature focuses on college students, it is necessary to conduct a detailed inquiry into the ways in which specific commitment and exploration processes develop over time for college students and for employed individuals. Two samples (456 college students and 318 employed individuals) were used to identify identity status trajectories over time and to examine external correlates of these trajectories (i.e. depressive symptoms, self‐esteem, identity centrality, community integration, and sense of adulthood). Similar identity trajectories emerged in both college students and employed individuals. Four of these trajectories corresponded to Marcia's identity statuses. In addition, apart from the ‘classical’ or troubled diffusion trajectory, a carefree diffusion trajectory was also obtained. Whereas individuals on an identity‐achieved pathway fared best in terms of the outcome measures, individuals in the troubled diffusion trajectory fared worst in terms of self‐esteem, depressive symptoms, and community integration over time. Implications and suggestions for future research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

The Significance of the Buddhist 10-Membered Formula of Dependent Origination

The dynamic process of karmic activity is one of the key philosophical concepts of the Buddhist doctrine, and is traditionally explained as the operation of a chain of 12 mutually interlinked members of dependent origination (pratītyasamutpāda). Textual research, however, reveals that a series of alternative chains of members of dependent origination coexisted prior to the systematization of this earlier textual material into the standardized list of 12 members. Such an alternative list consists of 10 members. This article examines the importance of this particular list of 10 members in the development of Yogācāra Buddhist philosophy. This philosophy, the basic interpretation of the mundane world of which is that the world around us only xists as the working of the human mind, i.e. the domain of perceptual consciousness (vijñāna), matured in the late fourth–early fifth century CE. This examination of the 10-fold formula of dependent origination also adds to our knowledge of the region of origin of Yogācāra philosophy, and thus on the geographical diversities within the development of Buddhist philosophy.     

Mindful Disintegration and the Decomposition of Self in Healthy Populations: Conception and Preliminary Study

The concept and quantification of ‘disintegration’ related to mindfulness were examined, i.e. attentional refinement to microscopic resolution wherein constituents of matter are decomposed into elemental units. Thus, perceptual data are synthesized less coherently. To explore this hypothesis, neural substrates of perceptual disorganization (high-frequency EEG event-related synchronization dynamics—ERD/ERS) and contextual meaning (N400 ERP) were investigated in healthy practitioners before and after a mindfulness retreat. N400 ERP amplitude attenuated, as did gamma-ERD. Shift from beta-ERD to beta-ERS was observed. These findings suggest: (1) mediated gamma-oscillations reflecting disrupted neural binding of visual representation/cohesion, (2) reduced N400 amplitude reflecting diminished extraction of contextual meaning, and (3) modulations in beta-synchrony that may serve to ‘stabilize’ cortical functioning during the transformative disintegrative process related to mindfulness, akin to a process of ‘non-reactivity’ at the cortical level. The latter may provide a candidate neural index for the construct of ‘equanimity’ within the mindfulness purview. An overarching interpretative framework of the results paralleling adaptive versus maladaptive disintegrative experience is further discussed.     

The role of daily need crafting in daily fluctuations in adolescents’ need-based and affective experiences

Based on self-determination theory, this diary study examined associations between adolescents’ daily need crafting and daily fluctuations in their need-based and affective experiences. We also examined the role of daily perceived autonomy-supportive parenting in adolescents’ daily need-crafting. Adolescents (N?=?159; M_age?=?15.56; 62% female) filled out a diary for seven consecutive days. Multilevel path analyses indicated that need crafting varied on a day-to-day basis, with daily need crafting relating positively to daily positive affect and negatively to negative affect. The benefits of daily need crafting were accounted for by higher daily need satisfaction and lower need frustration. Further, on days adolescents perceived more parental autonomy support, they reported more need satisfaction and less need frustration, an effect that was partially due to higher need crafting that day. Overall, the results suggest that need crafting represents a critical pro-active skill, with resulting benefits for adolescents’ daily need-based experiences and well-being.

Statistical Significance of the Contribution of Variables to the PCA solution: An Alternative Permutation Strategy

In this paper, the statistical significance of the contribution of variables to the principal components in principal components analysis (PCA) is assessed nonparametrically by the use of permutation tests. We compare a new strategy to a strategy used in previous research consisting of permuting the columns (variables) of a data matrix independently and concurrently, thus destroying the entire correlational structure of the data. This strategy is considered appropriate for assessing the significance of the PCA solution as a whole, but is not suitable for assessing the significance of the contribution of single variables. Alternatively, we propose a strategy involving permutation of one variable at a time, while keeping the other variables fixed. We compare the two approaches in a simulation study, considering proportions of Type I and Type II error. We use two corrections for multiple testing: the Bonferroni correction and controlling the False Discovery Rate (FDR). To assess the significance of the variance accounted for by the variables, permuting one variable at a time, combined with FDR correction, yields the most favorable results. This optimal strategy is applied to an empirical data set, and results are compared with bootstrap confidence intervals.     

Using trained pouched rats to detect land mines: another victory for operant conditioning

We used giant African pouched rats (Cricetomys gambianus) as land mine-detection animals in Mozambique because they have an excellent sense of smell, weigh too little to activate mines, and are native to sub-Saharan Africa, and therefore are resistant to local parasites and diseases. In 2009 the rats searched 93,400 m(2) of land, finding 41 mines and 54 other explosive devices. Humans with metal detectors found no additional mines. On average, the rats emitted 0.33 false alarm for every 100 m(2) searched, which is below the threshold given by International Mine Action Standards for accrediting mine-detection animals. These findings indicate that Cricetomys are accurate mine-detection animals and merit continued use in this capacity.     

Beyond shared perceptions of trust and monitoring in teams: implications of asymmetry and dissensus

Past research has implicitly assumed that only mean levels of trust and monitoring in teams are critical for explaining their interrelations and their relationships with team performance. In this article, the authors argue that it is equally important to consider the dispersion in trust and monitoring that exists within teams. The authors introduce "trust asymmetry" and "monitoring dissensus" as critical dispersion properties of trust and monitoring and hypothesize that these moderate the relationships between mean monitoring, mean trust, and team performance. Data from a cross-lagged panel study and a partially lagged study support the hypotheses. The first study also offered support for an integrative model that includes mean and dispersion levels of both trust and monitoring. Overall, the studies provide a comprehensive and clear picture of how trust and monitoring emerge and function at the team level via mean and dispersion.     

A process-content approach to adolescent identity formation: examining longitudinal associations between identity styles and goal pursuits

Research on identity focuses on the processes involved (e.g., identity style) or its content (e.g., goals and values), but limited research has addressed both issues simultaneously. The present study investigates cross‐lagged relations between identity styles (i.e., informational, normative, and diffuse‐avoidant) and goals (i.e., intrinsic vs. extrinsic and openness to change vs. conservation) in a 3‐wave adolescent sample (N = 806). Results support a reciprocal model, with process and content influencing each other. As for process effects, the informational and diffuse‐avoidant style predicted decreases in conservation goals, and the normative style predicted increases in conservation and extrinsic goals. As for content effects, conservation goals increased the normative style, and extrinsic goals decreased the informational and increased the diffuse‐avoidant style.     

Daily fluctuations in perfectionism dimensions and their relation to eating disorder symptoms

Multidimensional perfectionism has been shown to play an important role in eating disorders (EDs). However, research examining this relation has primarily focused on relatively stable inter-individual differences between persons, thereby failing to examine how these variables are associated within individuals on a daily basis. This study examines how daily fluctuations in Personal Standards (PS) perfectionism and Evaluative Concerns (EC) perfectionism relate to each other and to fluctuations in ED symptoms. Adolescents (N = 275) completed questionnaires each evening during seven consecutive days. Multilevel modeling showed significant day-to-day fluctuations in PS and EC perfectionism, and showed that both dimensions are intertwined in the day. Among females, fluctuations in EC perfectionism co-varied with fluctuations in ED symptoms.
