Hydrogen-induced cold cracking in heat-affected zone of low-carbon high-strength steel

The Y-groove cracking test by submerged arc welding was employed to study the susceptibility of a low-carbon high-strength steel to hydrogen-induced cold cracking (HICC). The morphology of hydrogen cracks was observed using an electron probe microscope. The results showed that the heat-affected zone (HAZ) has a higher susceptibility to HICC than the weld metal and that increasing heat input can improve the HICC resistance of the weldment. The intergranular microcracking is the main HICC mode at the lowest heat input condition, accompanied with some transgranular microcracks attached to complex inclusions. In combination with phase transformation behaviour in sub-zones, the effect of the phase transformation sequence is proposed to try to illustrate the fact that the fine-grained HAZ has higher probability of hydrogen cracking than the coarse-grained HAZ owing to the occurrence of hydrogen enrichment in the fine-grained HAZ after the transformation.     

The Meaning of Childbearing Among IVF Service Users Assessed via Laddering Technique

The psychosocial issues related to infertility have been widely researched. However, the meaning a couple gives to childbearing remains a relatively unexplored area. This study explores the meaning making of Hong Kong Chinese couples who had received in-vitro fertilization (IVF). Eleven IVF-successful and seven IVF-unsuccessful informants were assessed using two complementary constructivist methods: laddering technique and constructivist-grounded theory analysis of in-depth interviews. Findings revealed four aspects of symbolic meaning of childbearing focused on the informant's sense of self, cultural values, existential purpose, and relations with others. The results also depicted infertility as a form of disenfranchised grief, following ambiguous loss, underscoring the need for counselors to explore the meaning of childbearing among IVF service users and the impact on their self-narratives as a function of treatment outcome.     

Training Addiction Counselors to Implement an Evidence-Based Intervention: Strategies for Increasing Organizational and Provider Acceptance

One barrier to widespread public access to empirically supported treatments (ESTs) is the limited availability and high cost of professionals trained to deliver them. Our earlier work from 2 clinical trials demonstrated that front-line addiction counselors could be trained to deliver a manualized, group-based cognitive behavioral therapy (GCBT) for depression, a prototypic example of an EST, with a high level of adherence and competence. This follow-up article provides specific recommendations for the selection and initial training of counselors, and for the structure and process of their ongoing clinical supervision. We highlight unique challenges in working with counselors unaccustomed to traditional clinical supervision. The recommendations are based on comprehensive feedback derived from clinician notes taken throughout the clinical trials, a focus group with counselors conducted 1 year following implementation, and interviews with key organization executives and administrators.     

The role of religion in moderating the impact of life events on material life goals: some evidence in support of terror management theory

How would religion and a life event carrying an existential threat (LEET) jointly impact a person's life goals of becoming wealthy and successful in one's career? Goal reprioritisation, socioemotional selectivity, and gerotranscendence theories predict a shift away from material goals following a LEET, independent of the effect of religion. However, terror management theory (TMT) predicts that the effect of death thoughts depends on one's prevailing cultural values. As religion can be regarded as a culture, it is possible that Christians' and non-believers' material life goals would be differentially altered by LEET. Data from 1259 young Chinese adults reveal no main effect of LEET, but a strong effect of religion. Moreover, there was an interaction effect between LEET and religion on material life goals: LEET weakened material goals for Christians but not for non-believers. These findings suggest that TMT is more suitable than the other theories for predicting life goal changes.     

The Role of School-based Group Mentoring in Promoting Resilience among Vulnerable High School Students

This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents.

Family therapy in Macau: development,challenges and opportunities

Family therapy in Macau is in its early stages of development. The Satir model and structural family therapy were the first two therapies introduced. Later on, solution‐focused brief therapy and narrative therapy were also introduced. Macau has been undergoing dramatic socioeconomic changes since the relaxation of the gambling licenses. In sociocultural terms this has led to significant changes: the so‐called ‘dealer's complex’, gambling, drug abuse and youth deviance have become more prevalent. To address complicated family problems, various counselling institutes and training centres were established to conduct family therapy. However, there are still some limitations and challenges that must be addressed in order to have a thriving family therapy profession in Macau.     

Applicant Perceptions of Test Fairness: Integrating Justice and Self-Serving Bias Perspectives

The justice perspective is the current dominant framework for research on applicant perceptions of test fairness. Recently, an emerging perspective suggests that self-serving bias mechanisms may be operative in the development of test fairness perceptions. Using data from 494 actual applicants to an entry-level State Police Trooper position, this study integrates both the justice and self-serving bias perspectives to achieve a better understanding of test fairness perceptions. Results from structural equation modeling show that perceived job-relevance affects perceived fairness. In addition, test performance affects both perceptions indirectly through perceived performance.
