Sustainable career development for R&D professionals: Applying a career development system in Basque country

The goal of this study is to measure the effectiveness of a career development system implemented at a research and technology organization at satisfying the context requirements of a decree issued by the Basque Country government. Through in-depth surveying of 80 R&D professionals over the five years, the authors aimed to determine whether a career development system, when it is linked to context requirements and researchers’ contributions, could offer researchers feedback about their career aims and increase their job satisfaction. During the five years of the study, the researchers’ capacity to meet career requirements improved by 20%, and job satisfaction, although it declined at first, increased substantially in the last two years, reaching a historic high for the employee satisfaction survey.

Acculturation and academic achievement of rural to urban migrant youth: The role of school satisfaction and family closeness

China's 'tidal wave' of rural to urban migration has had a tremendous impact on the educational outcomes of its children. It remains unexplored how and when do migrant children’s experience of acculturation following arrival in the place of settlement influence their academic achievement. This study used a stratified cross-sectional sample of 2412 Chinese migrant children and adolescents aged 10–18 (Mean = 14, 45 % female) to investigate the role of school satisfaction and family closeness in the relationship between acculturation patterns and academic achievement. Acculturation patterns are derived from the bidimensional model proposed by Berry (2005). The results indicated that integration had a positive association with concurrent academic achievement. School satisfaction was a mediator between integration and academic achievement. Furthermore, the full mediation of school satisfaction was only supported when there was a high level of family closeness. Findings from this study underline the usefulness of the bi-dimensional model in understanding the individual differences in academic achievement and suggest greater attention to the cultural variations in interpersonal functioning at the family and school context.     

Coping With the Unexpected in Childbirth: A Thematic Analysis

This article reports original research that describes new mothers'' experiences of birth and maternity care. Qualitative data were collected through a survey on birth satisfaction, which included space for women to provide comments about their birth and experience of care. Thirty-nine women provided comments that were analyzed using the thematic analysis method. Two themes emerged from the women''s experiences: “Unexpected birth processes: expectations and reality” and “Coping with birth: the role of health-care staff.” Participants described unexpected birthing processes, their experiences of care, and maternity care staff''s contributions to coping with birth. Implications for practice for childbirth professionals include promotion of physiologic birth, respectful person-centered care during all phases of perinatal care, and the value of childbirth preparation.
