Compared to Internet and mobile communications, computer and video games are little used for psychotherapy, (psychosocial) counseling or coaching. This also applies to Serious Games, i.?e. interactive computer games that train cognitive or behavioral skills in a digital learning environment. Avatar-based coaching can be relevant for the coaching practice which includes design features and functional principles of Serious Games and whose example can be used to derive usage potential and risks for both coachs and clients.  相似文献

In 2015, the United Nations (UN) issued probabilistic population projections for all countries up to 2100, by simulating future levels of total fertility and life expectancy and combining the results using a standard cohort component projection method. For the 40 countries with generalized HIV/AIDS epidemics, the mortality projections used the Spectrum/Estimation and Projection Package (EPP) model, a complex, multistate model designed for short-term projections of policy-relevant quantities for the epidemic. We propose a simpler approach that is more compatible with existing UN projection methods for other countries. Changes in life expectancy are projected probabilistically using a simple time series regression and then converted to age- and sex-specific mortality rates using model life tables designed for countries with HIV/AIDS epidemics. These are then input to the cohort component method, as for other countries. The method performed well in an out-of-sample cross-validation experiment. It gives similar short-run projections to Spectrum/EPP, while being simpler and avoiding multistate modelling.  相似文献

This research compared direct and indirect measures of ambivalence, 2 commonly used strategies for measuring intergenerational ambivalence between older parents and their adult children. Directly and indirectly measured ambivalence, corresponding to felt and potential manifestations of the construct, were contrasted with each other and across generations. Data were derived from 253 older parent–adult child dyads participating in the Longitudinal Study of Generations in 2005. Direct and indirect measures of ambivalence were moderately correlated with each other within each generation. Children expressed greater indirect ambivalence than their parents but were no different than their mothers or fathers in their levels of direct ambivalence. Multivariate regression analyses examining the relationship between each type of ambivalence with individual and relationship characteristics found differences in associations across equations. The results suggest that direct and indirect measures are related but represent 2 distinct conceptions of ambivalence. This research highlights the challenges in understanding the full complexity of intergenerational relations and suggests that both generational perspectives be considered in future research.  相似文献

Individuals who engage in risky sexual behavior face the possibility of experiencing negative consequences. One tenet of social learning theory is that individuals engage in behaviors partly based on observations or perceptions of others’ engagement in those behaviors. The present study aimed to document these norms–behavior relationships for both risky and protective sexual behaviors, including alcohol-related sexual behavior. Gender was also examined as a possible moderator of the norms–behavior relationship. Undergraduate students (n = 759; 58.0% female) completed a Web-based survey, including various measures of drinking and sexual behavior. Results indicated that students underestimate sexual health-protective behaviors (e.g., condom use and birth control use) and overestimate the risky behaviors (e.g., frequency of drinking prior to sex, typical number of drinks prior to sex, and frequency of casual sex) of their same-sex peers. All norms were positively associated with behavior, with the exception of condom use. Furthermore, no gender differences were found when examining the relationship between normative perceptions and behavior. The present study adds to the existing literature on normative misperceptions as it indicates that college students overestimate risky sexual behavior while underestimating sexual health-protective behaviors. Implications for interventions using the social norm approach and future directions are discussed.  相似文献

Many theoretical models examining health risk behaviors, such as sexual risk taking, assume intentions directly predict behavior, and intentions are sometimes measured as a proxy for behavior. Given that there is often a discrepancy between intentions and behaviors (e.g., Sheeran, 2002 ), this study addressed factors that predict intention-behavior congruence. Specifically, utilizing a prospective design, the goal of the study was to determine if characteristics of university students' last sexual encounter predicted whether those students who intended to use condoms, contraception, or dual methods did so in their last sexual encounter with both relationship and casual partners. The seven tested variables were condom planning and preparatory behaviors, mood, sexual arousal, substance use, perceived partner attractiveness, intention certainty, and intention stability. Data were collected from 520 American undergraduate students at a medium-sized university. The six discriminant function analyses examining the intention-behavior relationship were able to correctly classify between 74% and 92% of the participants concerning whether intenders engaged in safe sex behaviors. The variables that best discriminated between behavior engagement over the six analyses were intention stability, intention certainty, and engagement in condom preparatory behaviors. The implications of these results for sexual risk prevention and intervention research are discussed.  相似文献

This article examines the notion of ‘family’ to consider how it may be understood in people's everyday lives. Certain recurrent and powerful motifs are apparent, notably themes of togetherness and belonging, in the context of a unit that the person can be ‘part of’. At the same time, there may be important variations in the meanings given to individuality and family, evoking differing understandings of the self and personhood. I consider these ideas further through globally relevant but variable cultural themes of autonomy and relationality, suggesting the term ‘social person’ as a heuristic device to distinguish the sense of ‘close‐knit selves’ that may be involved in some understandings of personhood. I argue that this version of personhood may be powerfully expressed through ‘family’ meanings, with a significance which can be at least provisionally mapped along lines of inequality and disadvantage within and between societies around the world. These forms of connectedness may be hard to grasp through those theoretical and methodological frameworks which emphasize the (relational) individual. I argue that, in affluent English speaking societies, 1 there may be little alternative to the language of ‘family’ for expressing such forms of relationality and connection.  相似文献

We measured the use of patronizing speech among young adults who were instructed to provide directions (via an internet connection) to a newcomer to campus described as 21 or 65?years old. As predicted, the acoustic properties used with older adults were moderated by the speakers?? history with older unrelated adults (no comparable effects were found for speakers?? history with grandparents). Participants with relatively low contact with unrelated older adults were more likely than those with high contact to be judged as sounding ??patronizing?? and to display acoustical properties associated with patronization (high vocal intensity, high pitch) with older newcomers. However, participants showed a shared tendency to speak more slowly to older than young adults. Findings inform our understanding of the circumstances under which ageist speech is amplified or attenuated.  相似文献

Health and safety issues in a vocational training center were explored in this study. Several sources and methods were used: group interviews with students in traditionally female [F] and male [M] trades, i.e. hairdressing (7 F) and automated systems electromechanics (8 M, 1 F); self-administered questionnaires on injuries sustained at the school; observations of activities in these programs; and analysis of ministerial documents. Findings indicate that the partially divergent ways that OHS is addressed in these programs cannot be explained only by the specific characteristics of the two trades. Some aspects put female students in hairdressing at a disadvantage: status accorded to OHS in the study programs, learning activities, and conditions for learning and managing prevention and injuries. The discussion focuses on a gender-differentiated analysis, the importance of improving the way OHS is addressed in the programs, in particular, those primarily involving female students, and the need to pursue research. In addition, the results from individual interviews with women (5 F) training for non-traditional trades lead to discussion on the interrelated effects of sex-based gender and professional gender.  相似文献
