Engaged at Work and Happy at Home: A Spillover–Crossover Model

The current diary study among 50 Spanish dual-earner couples examines whether engagement at work has an impact on own and partners’ well-being. Based on the Spillover–Crossover model, we hypothesized that individuals’ work engagement would spill over to the home domain, increasing their happiness level at the end of the day. Moreover, we predicted a crossover of happiness between the members of the couple. Participants filled in a diary booklet during five consecutive working days (N = 100 participants and N = 500 occasions). The results of multilevel analyses showed that daily work engagement has a direct effect on daily happiness. We also found that employees’ daily work engagement influenced partner’s daily happiness through employees’ daily happiness. Finally, results showed a clear bidirectional crossover of daily happiness between both members of the couple. These findings indicate that the positive effects of work engagement go beyond the work setting and beyond the employee.     

Infants’ vocalizations at 6 months predict their productive vocabulary at one year

Long before their first words, children communicate by using speech-like vocalizations. These protophones might be indicative of infants’ later language development. We here examined infants’ (n = 56) early vocalizations at 6 months (vocal reactivity scale of the IBQ-R) as a predictor of their expressive and receptive language at 12 months (German version of the CDI). Regression analyses revealed vocalizations to significantly predict expressive, but not receptive language. Our findings in German-learning 6-month-olds extend previous predictive evidence of early vocalizations reported for older infants. Together these findings are informative in light of early assessments monitoring typical and atypical language development.     

Does childhood general cognitive ability at age 12 predict subjective well-being at age 52?

Drawing on a broad, multidimensional conceptualization of subjective well-being, this study examined the power of childhood general cognitive ability to predict life satisfaction, satisfaction with eight individual life domains, and the frequency of experiencing positive and negative affect in middle adulthood. Data were obtained from a representative Luxembourgish sample (N = 738; 53% female) in a longitudinal study conducted in 1968 and 2008. Childhood general cognitive ability was unrelated to life satisfaction, negatively related to negative affect and satisfaction with free time, and positively related to positive affect and satisfaction with some of the life domains associated with socioeconomic success (i.e. finances, self, housing, work, or health). This predictive power persisted even when childhood socioeconomic status was controlled.     

Are behaviors at one alternative in concurrent schedules independent of contingencies at the other alternative?

Some have reported changing the schedule at one alternative of a concurrent schedule changed responding at the other alternative (Catania, 1969), which seems odd because no contingencies were changed there. When concurrent schedules are programmed using two schedules, one associated with each alternative that operate continuously, changing the schedule at one alternative also changes the switch schedule at the other alternative. Thus, changes in responding at the constant alternative could be due to the change in the switch schedule. To assess this possibility, six rats were exposed to a series of conditions that alternated between pairs of interval schedules at both alternatives and a pair of interval schedules at one, constant, alternative and a pair of extinction schedules at the other alternative. Comparing run lengths, visit durations and response rates at the constant alternative in the alternating conditions did not show consistent increases and decreases when a strict criterion for changes was used. Using a less stringent definition (any change in mean values) showed changes. The stay/switch analysis suggests it may be inaccurate to apply behavioral contrast to procedures that change from concurrent variable‐interval variable‐interval schedules to concurrent variable‐interval extinction schedules because the contingencies in neither alternative are constant.     

Recovery at home and performance at work: A diary study on self–family facilitation

This 5-day diary study among 65 Dutch employees focuses on the interplay between time on and off the job. We examined how daily off-job (work-related, physical, household) activities, in combination with the degree to which people want to engage in these activities relate to self–family facilitation (i.e., the positive influence of the fulfilment of one's own interests on one's family life). Further, we tested whether self–family facilitation relates to psychological detachment from work, recovery, and finally whether recovery relates to job performance. Multilevel analyses revealed that household activities enhance self–family facilitation only on days that people want to engage in such activities. Furthermore, spending time on household activities hinders psychological detachment on days people do not want to spend time on these activities. In addition, self–family facilitation and psychological detachment relate to better recovery the next morning. Finally, feeling recovered in the morning is beneficial for task performance during work. These findings emphasize the role of one's “wants” in the degree to which off-job activities lead to recovery. Furthermore, the results highlight the importance of keeping a good interaction between the self and the family for daily recovery and performance.     

Are parrots poor at motor self-regulation or is the cylinder task poor at measuring it?

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self-control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was challenged when three Corvus species (corvids) were found to parallel great apes despite having much smaller absolute brain sizes. However, new analyses suggest that it is the number of pallial neurons, and not absolute brain size per se, that correlates with levels of motor inhibition. Both studies used the cylinder task, a detour-reaching test where food is presented behind a transparent barrier. We tested four species from the order Psittaciformes (parrots) on this task. Like corvids, many parrots have relatively large brains, high numbers of pallial neurons, and solve challenging cognitive tasks. Nonetheless, parrots performed markedly worse than the Corvus species in the cylinder task and exhibited strong learning effects in performance and response times. Our results suggest either that parrots are poor at controlling their motor impulses, and hence that pallial neuronal numbers do not always correlate with such skills, or that the widely used cylinder task may not be a good measure of motor inhibition.     

Plato＇s Attempts at Defining Sophistry

In the Sophist, Plato offers seven definitions of a sophist. In this paper I will consider the relationship between these definitions, and examine how the first six definitions contribute to the final definition, and how the final definition, in turn, incorporates elements of the first six. Through this examination, we can also have a better grasp of Plato＇s method of division, and Plato＇s aporetic approach to philosophy.     

介词at与to的认知思辨

at这个英语单词包含攻击性意思,而to这个单词不具有此意思,主要的原因是这个词语强调将行为动作集中于一个点,这就意味着将动作对象缩小、弱化,由此蕴含一定的攻击性.     

“Visiting Day” at Rikers Island

Wacquant (2002) calls for ethnography to meet the jailhouse on its own terms, noting the dearth of first-hand writing from the carceral facility. This article describes a creative representation of qualitative research made by the author and two creative collaborators that both meets Wacquant’s call and problematizes it; meets it, as we depict the functioning of the visitation process at Rikers Island based on our first-hand experience on both sides of the bars, and problematizes it, as we chose for our medium the zine, a creative form common to prison writing, yet not sufficiently academic by Wacquant’s standards. I offer a novel definition of the zine form grounded in the academic literature, describe the visitation process at Rikers and the making of the “Visiting Day” zine, and reflect on challenges to the binary of inside/outside the carceral facility, as well as the political stakes of this theoretical formulation.     

Is Counseling's Bottom Line at the Top?

Is the face-perception system human-specific at birth?

The present study investigates the human-specificity of the orienting system that allows neonates to look preferentially at faces. Three experiments were carried out to determine whether the face-perception system that is present at birth is broad enough to include both human and nonhuman primate faces. The results demonstrate that the newborns did not show any spontaneous visual preference for the human face when presented simultaneously with a monkey face that shared the same features, configuration, and low-level perceptual properties (Experiment 1). The newborns were, however, able to discriminate between the 2 faces belonging to the 2 different species (Experiment 2). In Experiment 3, the newborns were found to prefer looking at an upright, compared with an inverted, monkey face, as they do for human faces. Overall, the results demonstrate that newborns perceive monkey and human faces in a similar way. These findings are consistent with the hypothesis that the system underlying face preference at birth is broad enough to bias newborns' attention toward both human and nonhuman primate faces.     

Older drivers’ visual search behaviour at intersections

Previous research has indicated that older drivers are more likely to be involved in collisions in complex traffic scenarios like intersections even if they are not more involved in accidents in general. Moreover, being more vulnerable, the older driver is generally at higher risk of sustaining an injury when involved in a traffic accident. Even though there may be many factors leading to the over-involvement of older drivers in intersection collisions it is clear that the visual capacity and the ability to observe may be one of the possible causes that is of high interest to understand further. The objective of the study is to identify to what degree the visual behaviour could explain older drivers’ involvement in intersection accidents. A 20 km long route composed by intersections in rural and urban environment was selected to collect both driving and eye movement data. Two groups of drivers were compared, one group aged 35–55 years and one aged 75 and above. Apart from the driving data, neck flexibility measurement was performed. The results from the neck flexibility measurement showed a clear age effect, with the older drivers showing less neck flexibility. When it comes to visual behaviour data, a difference was also found concerning the area of interest the drivers looked at; while the older drivers looked more at lines and markings on the road to position themselves in the traffic, the younger drivers looked more at dynamic objects such as other cars representing a possible threat. The difference in the visual behaviour should be used to design safety systems for all drivers to support them when they drive through an intersection.     

Humankind at a Turning Point? Feminist Perspectives

This paper was presented at the XIX World Congress of Philosophy, “Mankind at a Turning Point: Philosophical Perspectives” held in Moscow, August 22-28, 1993. The author, representing the International Association of Women Philosophers, criticizes the use of “Mankind” in the Congress title and incorporates a resolution, subsequently passed unanimously by the steering committee of the Fédération Internationale des Sociétés de Philosophic, that calls for the use of non-sexist language at future World Congresses.     

Are UN Peacekeepers at Risk for Suicide?

Media reports connecting UN peacekeeping duties by Canadian soldiers to their subsequent suicide prompted this study of peacekeeping as suicide risk. In a case-control design we retrospectively compared 66 suicides in the Canadian military between 1990 and 1995 with two control groups: (a) 2,601 controls randomly selected from the electronic military database and (b) 66 matched controls with complete personnel and medical data. We found no increased risk of suicide in peacekeepers except among a subgroup of air force personnel. Here confounding individual factors, isolation from supports, and possibly inadequate preparation for deployment elucidated their suicides. Theater of deployment (e.g., Bosnia) did not affect the suicide rate. Military suicides experienced psychosocial stresses and psychiatric illness more often than their matched controls. We conclude that although peacekeeping per se does not increase overall suicide risk, military life-styles may strain interpersonal relationships, encourage alcohol abuse, and contribute to psychiatric illness and suicide in a minority of vulnerable individuals irrespective of peacekeeping assignment. Careful selection, and preparatory military training that encourages intragroup bonding and mutual support, may protect against suicide risk.
