A gradual decline in functional and mental capacity, as well as a growing risk of care dependency constitute major concerns of life in old age. These are expected to become more urgent in the future, because the old-age dependency ratio in the EU is projected to nearly double until 2060 due to demographic change. On the other side, there is a strong desire to maintain the autonomy of older people as long as possible. In reaction to this, there have been strong health and social policy recommendations across Europe to develop and promote the use of assistive technologies (ATs). Whereas systematic reviews already exist for several kinds of ATs, reviews about self-care ATs are still missing. Based on a systematic literature search in PsycINFO, MEDLINE, and Google Scholar databases 203 papers were identified of which 13 were included according to our selection criteria. The methodological quality of all the reviewed studies is evaluated. We reviewed findings on objective and subjective indicators of independent living as efficiency criteria as well as evidence about facilitating and inhibiting factors in the use of these technologies. Self-care ATs turned out to be efficient, with respect to care hours, independence level, and self-reported satisfaction. The actual use of these ATs was influenced by diverse personal, contextual, and device aspects. Lack of randomized control trial studies and the need for a further research about ATs in the diverse subdomains of self-care activities is revealed. Based on the findings of the current study, we generate recommendations for future research. [less ▲]

Two studies (participants: N =126; N = 247) examined the reliability and validity of the German version of the Self-Concept Clarity Scale (Stucke, 2002). The results from exploratory and confirmatory factor analysis showed a one-factor solution fit best for adults, whereas a two-factor solution fit best for adolescents. Internal reliability was high for adult and adolescent samples. In adults, self-concept clarity was negatively correlated with both narcissism and self-reported aggression. The German version of the SCCS is a useful scale for predicting aggression, especially in adults. [less ▲]

The generalized internal/external frame-of-reference (G)I/E model explains the formation of domain-specific motivational-affective constructs through social and dimensional comparisons. We examined the associations between verbal and math achievement and corresponding domain-specific academic self-concepts (ASCs) and interests for first-graders and third-graders (N=21,192). Positive achievement-self-concept and achievement-interest relations were found within matching-domains in both grades, while negative cross-domains achievement-self-concept and achievement-interest relations were only found for third-graders. These findings suggest that while the formation of domain-specific ASCs and interests seem to rely on social and dimensional comparisons for third-graders, only social comparisons seem to be in operation for first-graders. Gender and cohort invariance was established in both grade levels. Findings are discussed within the framework of ASC differentiation and dimensional comparison theory. [less ▲]

We propose a self-consistent generalized quantum master equation (GQME) to describe electron transport through molecular junctions. In a previous study [Esposito, M.; Galperin, M. Phys. ReV. B 2009, 79, 205303], we derived a time-nonlocal GQME to cure the lack of broadening effects in Redfield theory. To do so, the free evolution used in the Born-Markov approximation to close the Redfield equation was replaced by a standard Redfield evolution. In the present paper, we propose a backward Redfield evolution leading to a time-local GQME which allows for a self-consistent procedure of the GQME generator. This approach is approximate but properly reproduces the nonequilibrium steady-state density matrix and the currents of an exactly solvable model. The approach is less accurate for higher moments such as the noise. [less ▲]

Self-control is typically conceptualized as an inherent human skill, focusing on the imperative control of thoughts, feelings, and behavior. In the present research, we scrutinize this understanding by differentiating between an ability self-concept of self-control strength and experiential acts of self-control. Moreover, by taking a motivational perspective, we analyze how much of a role intrapsychic conflict plays in both conceptions of self-control, and with regard to psychological well-being. In cross-sectional Study 1 (N = 228), we compared a typicality measure of experiential acts of imperative self-control with the widely used Self-Control Scale (Tangney et al. in J Pers 72:271-322, 2004). Findings confirm that "being good" at self-control does not correspond to "acting" self-controlled, and that both measures show opposing relationships to intrapsychic conflict, as well as to well-being. In Study 2 (N = 114), we corroborated these findings by using an experience-sampling approach. Multilevel analyses showed that between-person differences (Level 2) in self-control strength were generally unrelated to experiential acts of self-control in everyday life. By contrast, we found a positive Level 2 effect for acting self-controlled. With regard to momentary affect, both between- and within differences (Level 1) in acting self-controlled served as substantial predictors, in addition to momentary self-determination. Other context-dependent effects (i.e., studying vs. leisure time) further emphasize the need to consider motivational interpretations of self-control (strength). [less ▲]
