The study examined the mediating role of individual’s self-regulatory processes of deep cognitive strategies (meaningful learning rather than a reproduction of knowledge) and negative affect in the relationship between dispositional and team goal orientations and team member’s performance of complex tasks. Thirty-three research and development teams and their managers participated. Results demonstrated that dispositional performance orientation (focus on success) increased negative affect, which, in turn, lowered employee job performance. Whereas team learning orientation (focus on learning and improvement) decreased negative affect, which, in turn, was associated with higher employee job performance. Additionally, both dispositional and team learning orientations were positively and significantly associated with individuals’ use of deep cognitive strategies. However, deep cognitive strategies were not associated with employee performance. Findings suggest that managers of teams performing complex tasks may want to consider ways to create and sustain a high learning orientation in order to reduce negative affect and increase use of deep cognitive strategies within their teams.

The Ideal

The reconstruction of a three-dimensional image of a specimen from a set of electron micrographs reduces, under certain assumptions about the imaging process in the microscope, to the mathematical problem of reconstructing a density distribution from a set of its plane projections.In the absence of noise we can formulate a purely geometrical criterion, which, for a general object, fixes the resolution attainable from a given finite number of views in terms of the size of the object. For simplicity we take the ideal case of projections collected by a series of m equally spaced tilts about a single axis.

From X-ray analysis, the conclusions are drawn from averaged molecular informations. Thus, limitations are caused when analyzing systems whose symmetry is reduced due to interatomic interactions. In contrast, scanning tunneling microscopy (STM) directly images atomic scale surface electron density distribution, with a resolution up to fractions of Angstrom units. The crucial point is the correlation between the electron density distribution and the localization of individual atoms, which is reasonable in many cases. Thus, the use of STM images for crystal structure determination may be permitted. We tried to apply RuCl3 - a layered material with semiconductive properties - for such STM studies. From the X-ray analysis it has been assumed that α-form of this compound crystallizes in the monoclinic space group C2/m (AICI3 type). The chlorine atoms form an almost undistorted cubic closed package while Ru occupies 2/3 of the octahedral holes in every second layer building up a plane hexagon net (graphite net). Idealizing the arrangement of the chlorines a hexagonal symmetry would be expected. X-ray structure determination of isotypic compounds e.g. IrBr3 leads only to averaged positions of the metal atoms as there exist extended stacking faults of the metal layers.

Abstract Functional capacity evaluations (FCEs) have become an important component of disability evaluation during the past 10 years to assess an individual's ability to perform the essential or specific functions of a job, both preplacement and during rehabilitation. Evaluating both job performance and physical ability is a complex assessment, and some practitioners are not yet certain that an FCE can achieve these goals. An FCE is useful only if it predicts job performance, and factors that should be assessed include overall performance; consistency of performance across similar areas of the FCE; consistency between observed behaviors during the FCE and limitations or abilities reported by the worker; objective changes (eg, blood pressure and pulse) that are appropriate relative to performance; external factors (illness, lack of sleep, or medication); and a coefficient of variation that can be measured and assessed. FCEs can identify specific movement patterns or weaknesses; measure improvement during rehabilitation; identify a specific limitation that is amenable to accommodation; and identify a worker who appears to be providing a submaximal effort. FCEs are less reliable at predicting injury risk; they cannot tell us much about endurance over a time period longer than the time required for the FCE; and the FCE may measure simple muscular functions when the job requires more complex ones.

Low Levels

The current study was an attempt to determine the degree to which the suppression of respiratory sinus arrhythmia (RSA) and attentional control were influential in the ability to engage various executive processes under high and low levels of negative affect. Ninety-four college students completed the Stroop Test while heart rate was being recorded. Estimates of the suppression of RSA were calculated from each participant in response to this test. The participants then completed self-ratings of attentional control, negative affect, and executive functioning. Regression analysis indicated that individual differences in estimates of the suppression of RSA, and ratings of attentional control were associated with the ability to employ executive processes but only when self-ratings of negative affect were low. An increase in negative affect compromised the ability to employ these strategies in the majority of participants. The data also suggest that high attentional control in conjunction with attenuated estimates of RSA suppression may increase the ability to use executive processes as negative affect increases.

Lack Of Knowledge

Metacognitive awareness of memory failure may take the form of the “blank in the mind” (BIM) experience. The BIM experience informs the person of a temporary memory failure and takes the form of a disruption in the flow of consciousness, of a moment of no content in awareness. The aim of the present study was to examine the psychometric properties of the Blank in the Mind Questionnaire (BIMQ) designed to tap the BIM experience and differentiate it from other memory-related experiences, such as searching but not having in memory a piece of information (i.e., lack of knowledge). The participants (N = 493) were 249 younger adults (18–30 years old) and 244 older adults (63–89 years old) of both genders. Confirmatory factor analysis applied to the BIMQ confirmed a three-factor model with interrelations between the factors. The first factor represented the experience of lack of knowledge, the second represented the experience of BIM, and the third the person’s negative affective reactions to memory failure. The internal consistency of the three factors ranged from Cronbach’s α = .80 to .88. Convergent validity was shown with correlations of the BIMQ factors with self-report measures of cognitive and memory failures, and to the negative-affect subscale of the Positive and Negative Affect Schedule (PANAS).

Diary Research

This article presents an overview of the literature on daily fluctuations in work engagement. Daily work engagement is a state of vigor, dedication, and absorption that is predictive of important organizational outcomes, including job performance. After briefly discussing enduring work engagement, the advantages of diary research are discussed, as well as the concept and measurement of daily work engagement. The research evidence shows that fluctuations in work engagement are a function of the changes in daily job and personal resources. Particularly on the days that employees have access to many resources, they are able to cope well with their daily job demands (e.g., work pressure, negative events), and likely interpret these demands as challenges. Furthermore, the literature review shows that on the days employees have sufficient levels of job control, they proactively try to optimize their work environment in order to stay engaged. This proactive behavior is called job crafting and predicts momentary and daily work engagement. An important additional finding is that daily engagement has a reciprocal relationship with daily recovery. On the days employees recover well, they feel more engaged; and engagement during the day is predictive of subsequent recovery. Finding the daily balance between engagement while at work and detachment while at home seems the key to enduring work engagement.

Abstract. This study investigated the factor structure and measurement invariance of the Mroczek and Kolarz’s scales of positive and negative affect in Iran (N = 2,391) and the USA (N = 2,154), and across gender groups. The two-factor model of affect was supported across the groups. The results of measurement invariance testing confirmed full metric and partial scalar invariance of the scales across cultural groups, and full metric and full scalar invariance across gender groups. The results of latent mean analysis revealed that Iranians scored lower on positive affect and higher on negative affect than Americans. The analyses also showed that American men scored significantly lower than American women on negative affect. The significance and implications of the results are discussed.

Abstract. We examined the negative outcomes, particularly social costs that result when a person harms their group by performing poorly, and whether self-compassion could buffer against these negative outcomes. In Studies 1 and 2, participants performed poorly and harmed their group or performed equal to their group. Harmful poor-performing participants felt more burdensome, experienced more negative affect, felt more ostracized, anticipated more exclusion, and felt lowered self-esteem than equal-performing participants. Studies 3 and 4 disentangled poor performance from harming a group. Poor-performing participants either harmed the group or caused no harm. Harmful poor-performing participants felt more burdensome and anticipated more exclusion, indicating the additional social consequences of a harmful poor performance over a non-harmful performance. Across studies, trait self-compassion was associated with reduced negative effects.
