One instrument focuses on evaluations of the parents and the other on evaluations of their child’s development. Both instruments are presented after an adoption vignette in which the sexual orientation and relational status of the prospective adoptive parents and the gender of the adopted child were varied. First, we determined the factorial structure of the two instruments using exploratory factor analysis. Second, we validated the observed factorial structures using confirmatory factor analysis. Third, we tested the measurement invariance of this model across the prospective adoptive parents’ sexual orientation, relational status, and gender of their adopted child using multiple-group confirmatory factor analysis. The two instruments showed good psychometric qualities and proved to be reliable resources to measure diverse aspects of attitudes toward same-sex parenting.

The system comprises an analog signal processor, a control interface circuit, and a microprocessor that controls the sequence of operations.

As dual-earners are now a majority and men and women's roles in both the workplace and at home have changed, questions have been raised regarding how individuals and couples can balance family and work. Nevertheless, research addressing work-family conciliation strategies is limited to a conflict-driven approach and context-specific instruments are scarce. This study develops an instrument for assessing how dual-earners manage their multiple roles detaching from a conflict point of view highlighting the work-family conciliation strategies put forward by these couples. Through qualitative and quantitative procedures the Work-Family Conciliation Strategies Scales was developed and is composed by 5 factors: Couple Coping; Positive Attitude Towards Multiple Roles, Planning and Management Skills, Professional Adjustments and Institutional Support; with good adjustment [χ2/df = 1.22; CFI = .90, RMSEA = .04, SRMR = .08.] and good reliability coefficients [from .67 to .87]. The developed scale contributes to research because of its specificity to the work-family framework and its focus on the proactive nature of balancing work and family roles. The results support further use of this instrument.

The present study aimed at capturing (1) the relative weight of parental financial support and autonomy support in contributing to the youngsters' psychological well-being (PWB), and (2) the mediating role of identity capital and uncertainty management in this relationship. A total of 620 participants completed measures of parental support, identity capital, uncertainty management and PWB. Autonomy support was found to be the strongest predictor of PWB, both directly and indirectly through its effects on identity capital and the use of target focused uncertainty management strategies. Conversely, financial support evidenced only a minor indirect impact through the mediation of tangible identity capital. Autonomy stimulation may constitute one of the most developmentally determinant family challenges in assisting the process of coming of age in Portugal.

According to the recommendations of the IEC Standard 544, mechanical tests are carried out, and the radiation degradation is measured after accelerated irradiations.

Participants were 768 Portuguese university students. Using a quasiexperimental design, participants were presented with identical descriptions of a couple interested in adopting a child, manipulating couple sexual orientation and child gender. Participants were then asked to anticipate three aspects of the sexual and gender development of the adopted child: sexual orientation, gender role behavior, and gender identity. MANOVAs and follow-up ANOVAs were conducted in order to analyze the data. Results indicated that participants, particularly males, considered children adopted by either lesbian or gay couples to have a lower probability of developing a normative sexual and gender identity than children adopted by heterosexual couples. Both men and women considered that children would emulate the sexual orientation of their same-sex parents, and that a boy's gender role behavior was more at risk if he was adopted by a lesbian couple. Moreover, men were apprehensive about the gender role behavior of a boy adopted by a gay male couple. Overall, these results indicate persistence of biased evaluations of the sexual and gender development of children adopted by lesbian and gay parents. Furthermore, both gender of the participant and gender of the child play an important role in these evaluations. Results are discussed and interpreted as a way of "doing gender" in the context of hegemonic masculinity.
