SYNOPSIS

Does work-family conflict influence parental behaviors and parenting-related emotional states? Through an experimental research approach, River and colleagues showed that work-family conflict influences both emotions and parental behaviors, but the effect is moderated by the quality of the intimate relationship. In this commentary, we offer an interpretation of the results congruent with the recent theoretical approaches that stress the need for a multisystem psycho-biological approach to studying the factors that regulate parenting behaviors. In this perspective, we provide complementary explanations of the observed results and suggest possible future directions for research on these topics.  相似文献

Objective. The aims of this article were to test the measurement invariance of the Italian and American versions of the Adult Parental Acceptance–Rejection Questionnaire and to compare adults’ remembrances of parental acceptance–rejection across the two nations. Design. The Adult Parental Acceptance–Rejection Questionnaire was administered to 564 Italian adults (M = 23.04 years) and 509 U.S. American adults (M = 22.09 years), matched by gender and age. The measurement invariance of the Parental Acceptance–Rejection Questionnaire was first established by means of multi-group confirmatory factor analyses. Results. The Parental Acceptance–Rejection Questionnaire is fully invariant across the two cultures, and adults organize their remembrances of mothers’ and fathers’ parenting around the same four classes of behavior in both nations. Italian and American adults tend to remember their parents as having been quite loving, with Italian parents being remembered as slightly less warm and more hostile than American parents. Conclusions. The full invariance of the Parental Acceptance–Rejection Questionnaire across the two populations represents additional strong evidence for the universality of interpersonal acceptance–rejection theory. Measurement invariance also confirmed that the Adult Parental Acceptance–Rejection Questionnaire (short form) can be used to measure adult remembrances of parental acceptance–rejection across these two populations.  相似文献

Piperno, a Late Quaternary magmatic rock cropping out on the eastern side of the Campi Flegrei (Italy), is probably the most important building stone of Naples, used over a time-span from at least the Roman age until the beginning of the 20th century. Despite its wide diffusion in the monumental architecture of Naples, very little is known about this rock, as regards its technical features, as well as the geological aspects. This paper aims at providing a first overall contribution towards a rediscovery of this long-time-used material, in view of careful restoration works, which nowadays at Naples only take into account the proper geological features of the stone in a few peculiar cases. Thus, it seems of extreme importance to understand the basic parameters of Piperno and, above all, its response to weathering agents. Main mineralogical, petrographical and engineering–geological properties are presented here for the first time, with specific reference to two sampling areas, located at Pianura and Soccavo, in the western sector of the Neapolitan urban area. As far as many of its physico–mechanical features are concerned, Piperno extends over a wide range of values, which allow different varieties of the rock to be identified. This preliminary result is seemingly in accordance with data from old historical literature, which stated the existence of six horizons in the Piperno formation.  相似文献

University administrators may invest significant time and resources with the goal of improving their U.S. News & World Report ranking, but the real impact of these investments is not well known since, as other universities make similar changes, rankings become a moving target. This research removes the mystique of the U.S. News ranking process by producing a ranking model that faithfully recreates U.S. News outcomes and quantifies the inherent “noise” in the rankings for all nationally ranked universities. The model developed can be a valuable tool to institutional researchers and university leaders by providing detailed insight into the U.S. News ranking process. It allows the impact of changes to U.S. News subfactors to be studied when variation between universities and within subfactors is present. Numerous simulations were run using this model to understand the effect of each subfactor individually and to determine the amount of change that would be required for a university to improve its rank or move into the top 20. Results show that for a university ranked in the mid-30 s it would take a significant amount of additional resources, directed in a very focused way, to become a top-ranked national university, and that rank changes of up to ± 4 points should be considered “noise”. These results can serve as a basis for frank discussions within a university about the likelihood of significant changes in rank and provide valuable insight when formulating strategic goals.  相似文献

ABSTRACT

The aim of this study was to investigate training load and cardiorespiratory fitness in a top-level Spanish (LaLiga) football team (n = 17). The submaximal Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1SUB) was performed in four moments of the competitive period from early February (E1) to early May (E4). Training load was quantified using a 10-Hz global positioning system and heart rate (HR) recording (n = 837 individual training sessions), while match load was quantified using semi-automated cameras (n = 216 individual match observations). Cardiorespiratory fitness moderately improved as the season progressed (P < 0.05; effect sizes = 0.8 to 1.2). Cumulative total distance covered during training between E1 and E4 was negatively correlated with percentage of changes in mean HR during the last 30 s of Yo-Yo IR1SUB (P = 0.049; r = ?0.47 [?0.71; ?0.14]; moderate). HR during the last 30 s of Yo-Yo IR1SUB was negatively correlated to total distance covered during the match (P = 0.024; r = ?0.56 [?0.80; ?0.17]; moderate). Yo-Yo IRSUB can be used to monitor seasonal changes in cardiorespiratory fitness without the need to have players work until exhaustion. Cardiorespiratory fitness given by mean HR during the last 30 s of the test seems meaningful in relation to match performance.  相似文献

The present work reports on a spectroscopic study of white colour samples collected from Etruscan polychromes on terracotta from the Cerveteri area. In particular, both white-on-red potsherds of the Orientalising period and high-value polychromes of the Archaic period were considered. The white pigment, a fundamental element in this class of artworks, was not clearly identified in previous archaeological and analytical studies, although the use of kaolin was tentatively proposed. Therefore, samples from the Monte Sughereto kaolin quarry in the Cerveteri area were also studied. The results of detailed analyses carried out using micro-Raman spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy first show that the quarry material is a high-purity kaolin containing quartz. Raman results strongly suggest that the same kind of kaolin was employed in the polychromes of the Archaic period. As to white-on red potsherds, infrared results have a key role in showing that the white pigment is a kaolin closely corresponding to the quarry material since a particular kaolin polytype (dickite) is dominant in both cases. The present work thus provides the first definitive identification of the white pigment used in Etruscan polychromes on terracotta from the Cerveteri area, and suggests that the source of kaolin might be the Monte Sughereto quarry.  相似文献

We carry out a randomized experiment involving undergraduate students enrolled at an Italian University attending two introductory economics classes to evaluate the impact on achievement of examination frequency and interim feedback provision. Students in the treated group were allowed to undertake an intermediate exam and were informed about the results obtained, while students in the control group could only take the final exam. The results show that students undertaking the intermediate exam perform better both in terms of the probability of passing the exams and of grades obtained. High ability students appear to benefit more from the treatment. The experiment design allows us to disentangle “workload division or commitment” effects from “feedback provision” effects. We find that the estimated treatment impact is due exclusively to the first effect, while the feedback provision has no positive effect on performance. Finally, the better performance of treated students in targeted examinations seems not to be obtained at the expenses of results earned in other examinations.  相似文献

The main aim of this study was to assess the physiological responses of male basketball players during usual basketball ball-drills. Fourteen male basketball players (age 18.9 ± 2.3 years) performed the following full-court (28 × 15 m) basketball ball-drills (3 × 4-min with 3-min passive rest): five-a-side (5v5), three-a-side (3v3) and two-a-side (2v2). A main effect (P < 0.0001) for ball-drills modes was evident for all variables (5v5 < 3v3 < 2v2). Mean [Vdot]O(2) during the 5v5, 3v3 and 2v2 were 39.0 ± 7.2, 42.0 ± 7.5 and 45.0 ± 6.5 ml · kg(-1) · min(-1) (69 ± 11, 74 ± 12 and 79 ± 11% of [Vdot]O(2peak)) respectively (5v5 = 3v3 < 2v2, P < 0.001). Mean blood-lactate concentrations for 5v5, 3v3 and 2v2 were 4.2 ± 1.8, 6.2 ± 2.3 and 7.8 ± 1.2 mmol (l(-1) respectively (5v5 < 3v3 < 2v2, P < 0.01). During the 5v5, 3v3 and 2v2 mean heart-rate (HR) was 84.0 ± 9.2, 88.0 ± 8.4 and 92.0 ± 5.6% of the individual peak respectively (5v5 < 3v3 < 2v2; P < 0.001). No significant differences were found between the regression-line slope (P = 0.86) and intercept (P = 0.45) of the HR-[Vdot]O(2) relationships of the multistage maximal fitness test (r(2) from 0.80 to 0.96, P < 0.001) and ball-drills (r(2) from 0.70 to 0.95, P < 0.001) conditions. Reducing the number of players over the same playing court resulted in increments in physiological demands. The 2v2 condition provided responses in the range of those reported to improve aerobic and anaerobic fitness. The aerobic demands of ball-drills can be accurately assessed using heart-rate monitoring in basketball.  相似文献
