We examined whether a supervisor's coaching leadership style predicts the perception of organizational politics in performance appraisal ( OPPA) reported by the collaborators. Additionally, we drew on social cognition and motivational life-span development theories to hypothesize age-related differences in perceived OPPA and its link with the coaching leadership style. Using hierarchical linear modeling ( HLM) on a sample of 576 employees and 112 leaders, we found that coaching leaders are perceived as less manipulative in their performance ratings, especially by older employees. This article includes a discussion of the implications these results have for performance management of an age-diverse workforce. © 2016 Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

Coaching is a developmental intervention implemented in organisations to improve individual attitudes and behaviours. Few studies, however, have tested these assumptions and explained the mechanisms involved. We propose psychological capital (PsyCap), a set of positive individual resources, as a possible mediator. We investigated whether coaching framed in goal setting and conservation of resources theories is effective in improving PsyCap and, through this, individual attitudes and performance, and whether its effects maintain over time. We conducted an experiment with 56 employees in a marketing company, who were either randomly assigned to a coaching intervention or a wait‐list control group. Measures of interest were collected before the programme started (T1), and after the programme, which lasted 4 months (T2). A follow‐up measure for the experimental group was collected after a further 4 months (T3). ANOVAs showed coaching was associated with increases in PsyCap, job attitudes, and one dimension of job performance. The mediating role of PsyCap was supported for job attitudes. The effects on PsyCap and job attitudes lasted over time, as revealed by within‐subjects repeated measures analyses. This study fills a gap in our knowledge of the explanatory processes of coaching effectiveness by building on solid research design features. [ABSTRACT FROM AUTHOR]

ABSTRACT Using the 2006 Eurobarometer data (representative sample of the European population, N = 16 306, 27 countries), we performed a multilevel analysis aimed at predicting fear of crime. A significant proportion of the variation in fear of crime was at country level. Of the individual predictors included, being a woman, being poorly educated, being unemployed, and being an urban dweller showed positive relations with fear of crime. Fear was highest among people who considered themselves to be socially marginal, among people with negative expectations regarding themselves and their country's future, and among people who considered their nation's welfare system to be unsatisfactory. Among the ecological predictors we took into consideration, nations' degree of economic inequality and low expenditure on education and on social protection showed a positive association with fear of crime, whereas the crime, immigration, and employment rates did not. Implications and limitations of this research are discussed. Copyright © 2013 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Past research adopting a configural approach to organisational commitment has yielded support for differentiated profiles (i.e. different combinations of different levels of commitment components) and for their relationship with attitudinal and behavioral outcomes. The present study aimed to: (a) investigate, in an Italian privatised organisation, the emergence of commitment profiles derived from the combination of affective (AC) and continuance (CC) organisational commitment, following Sinclair and colleagues' conceptualisation (2005); and (b) examine whether these profiles differed in absenteeism, as an objective outcome, job satisfaction, and job performance. Results from cluster analysis supported the presence of four groups (Allied, Free Agents, Trapped, and Complacent). The Allied and the Complacent profiles reported higher job satisfaction. Moreover, the Complacent profile displayed the highest job performance and the Allied showed the lowest level of absenteeism; both were significantly different from the Trapped profile. Implications for theory and practice are discussed. [ABSTRACT FROM AUTHOR]

Using a multilevel, longitudinal model, we tested the mugging thesis, which states that 'a conservative is a liberal who has been mugged', in a national sample of Italians (N = 457, nested in 54 counties) surveyed four times between October 2002 and January 2007. We predicted participants' increase in conservatism as a function of the cross-level interactions between criminal victimisation on the one hand and the unemployment and the crime rates for their areas of residence on the other. Conservatism increased among victimised participants living in areas characterised by high unemployment rates, but not among those living in areas with low unemployment rates. The cross-level interaction between victimisation and crime rate did not influence our dependent variable. The strengths, implications and limitations of this research are discussed.

In a national sample of the Italian population, surveyed four times between October 2002 and January 2007 ( N = 2,008), we performed a multilevel longitudinal study aimed at predicting the increase in crime risk perception as a function of three families of independent variables, respectively lying at the within individual level (direct victimization and indirect victimization), at the between-individuals level (being a woman, being an older person, being a poorly educated person and size of area of residence) and at the ecological level (county's crime rate, unemployment rate and immigration rate). Direct and indirect victimization, being a woman, being an older person, living in a large town and in a context characterized by high crime and unemployment rates positively influenced the change in crime risk perception, while the other individual and ecological predictors we used in our predictive model did not. Strengths, limitations, implications and future developments of this research are discussed. [ABSTRACT FROM AUTHOR]

Beckwith-Wiedemann syndrome (BWS), an overgrowth disorder with several congenital abnormalities, encompasses nephrourological anomalies. The objective of the report is to analyze the latter and related genotype-phenotype correlations. The study was a retrospective review of nephrourological investigations and genotype in 67 BWS patients. Imaging and laboratory studies have been correlated with the molecular anomalies typical of BWS. Thirty-eight (56.7%) patients had a total of 61 nonmalignant nephrourological findings, including nephromegaly ( n = 24), collecting system abnormalities ( n = 14), cryptorchidism ( n = 11), nephrolithiasis ( n = 5), cysts ( n = 5), and dysplasia ( n = 1). Four patients had Wilms' tumor, all associated with renal hyperplasia. Renal findings were almost consistent in the BWS group, with nephromegaly in all patients and collecting system abnormalities in half of them. BWS and negative patients also had frequent anomalies (63.6% and 61.9% respectively), whereas only 36.0% of BWS had renal findings ( p = 0.003). Cryptorchidism was associated with abdominal wall defects ( p < 0.001) appearing more frequently in BWS ( p = 0.028). Urinary tract infections were observed in 17.9% of patients, with two resulting in life-threatening sepsis. Hypercalciuria was present in 10% of cases. 55.5% of BWS patients have renal findings. Although variegate, these anomalies disclose a genotype-phenotype correlation. [ABSTRACT FROM AUTHOR]

Ovarian cancer (OC) is the most lethal gynecologic cancer characterized by an elevated apoptosis resistance that, potentially, leads to chemo-resistance in the recurrent disease. Mitochondrial oxidative phosphorylation was found altered in OC, and mitochondria were proposed as a target for therapy. Molecular evidence suggests that the deregulation of mitochondrial biogenesis, morphology, dynamics, and apoptosis is involved in carcinogenesis. However, these mitochondrial processes remain to be investigated in OC. Eighteen controls and 16 OC tissues (serous and mucinous) were collected. Enzymatic activities were performed spectrophotometrically, mitochondrial DNA (mtDNA) content was measured by real-time-PCR, protein levels were determined by Western blotting, and mitochondrial number and structure were measured by electron microscopy. Statistical analysis was performed using Student's t-test, Mann-Whitney U test, and principal component analysis (PCA). We found, in OC, that increased mitochondrial number associated with increased peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α) and mitochondrial transcription factor A (TFAM) protein levels, as well as mtDNA content. The OC mitochondria presented an increased maximum length, as well as reduced cristae width and junction diameter, associated with increased optic atrophy 1 protein (OPA1) and prohibitin 2 (PHB2) protein levels. In addition, in OC tissues, augmented cAMP and sirtuin 3 (SIRT3) protein levels were observed. PCA of the 25 analyzed biochemical parameters classified OC patients in a distinct group from controls. We highlight a "mitochondrial signature" in OC that could result from cooperation of the cAMP pathway with the SIRT3, OPA1, and PHB2 proteins. [ABSTRACT FROM AUTHOR]

Using a longitudinal design, we asked 2 age cohorts of adolescents (15- and 18-year-olds) whether they, during the last year, had experienced events that had increased their civic interest and about details of their experiences. Based on self-determination theory, we predicted that the adolescents who reported having experienced events of this kind had already been more interested and had had more positive feelings about politics much earlier in time, and that this original interest would have increased more over time, than that of other adolescents. Second, we proposed that the adolescents who had encountered events that triggered their civic interest would have been engaged in behaviors that reflected their needs for autonomy, relatedness, and competence, much earlier in time, and that, over time, they would have increased these behaviors more than other adolescents. These 2 predictions were largely confirmed. As for the content of the events the adolescents reported, many of them concerned national and international issues experienced as threatening, and that challenged the adolescents' beliefs and morality. Overall, a previous interest in politics and engagement in exploratory behaviors that reflect the adolescents' psychological needs seem to play crucial roles in understanding why adolescents in their everyday life encounter events that trigger their civic interest. Further, the findings show that having had everyday experiences that trigger the adolescents' civic interests are associated with a later increase in political interest more broadly.
