Newborns (N = 83) were presented with 3 conditions, each for 160 sec: tongue protrusion (TP), mouth opening (MO), and control (CO). In TP and MO, a female model alternated between demonstrating the gesture for 20 sec and presenting a passive, motionless face for 20 sec. In CO, she presented a passive face in both the “demonstration” and “passive” intervals. The participants' eyes were more widely open in the demonstration intervals of TP and MO than in the passive intervals, indicating that they were attending to the gestures. In TP, the participants produced more TP responses than MO responses, but in MO there was no effect, undermining the neonatal imitation hypothesis.  相似文献

ABSTRACT

The current systematic literature review aimed to analyse the associations between temporary agency work (TAW), job satisfaction, and mental health in Europe, as well as to outline a future research agenda. Twenty-eight scientific articles were identified by searching different data bases (i.e. PSYNDEX, PsycINFO, PubMed, and Web of Science) for the time span from January 2000 to December 2016. Our review reveals first that TAW is not consistently negatively related to job satisfaction. However, job insecurity and working conditions are important mediators in the relation of TAW and lowered job satisfaction. Second, TAW is not consistently related to all investigated types of mental health impairments. However, when focusing on specific outcomes and comparing temporary agency workers to permanent employees, we still find consistent evidence regarding higher levels of depression and fatigue among temporary agency workers. Inconsistent associations between TAW, job satisfaction and mental health can partly be attributed to unfavourable methodological aspects of the included primary studies. To address these aspects, future research should consider applying a standard measurement of TAW, including a minimum of meaningful confounding variables, improving the operationalisation of outcome variables and the study design.  相似文献

This paper investigates the influence of accounting standards on systematic earnings understatement. To isolate the effect of reporting regulations from those of other institutional drivers of earnings management, Holthausen (2003) proposes analyzing reporting practices in a country undergoing a transition in accounting standards. We respond to this call by analyzing earnings management practices of large German-listed companies before and after their transitions from German GAAP to IFRS. Specifically, we focus on Big Bath behavior following Chief Financial Officer turnovers between 1999 and 2006. Our findings provide evidence of the effect of accounting standards on the existence of this particular earnings understatement pattern. However, while we detect Big Bath behavior for our sample of German GAAP firms, we find no such indication for those firms reporting under IFRS. Controlling for alternative explanations such as self-selection bias does not change our findings. We conclude that accounting standards seem to have a considerable influence on earnings management behavior, independent of managers’ and auditors’ incentives.  相似文献

The analysis of recurrent event data in clinical trials presents a number of difficulties. The statistician is faced with issues of event dependency, composite endpoints, unbalanced follow‐up times and informative dropout. It is not unusual, therefore, for statisticians charged with responsibility for providing reliable and valid analyses to need to derive new methods specific to the clinical indication under investigation. One method is proposed that appears to have possible advantages over those that are often used in the analysis of recurrent event data in clinical trials. Based on an approach that counts periods of time with events instead of single event counts, the proposed method makes an adjustment for patient time on study and incorporates heterogeneity by estimating an individual per‐patient risk of experiencing a morbid event. Monte Carlo simulations demonstrate that, with use of a real clinical study data, the proposed method consistently outperforms other measures of morbidity.

The term “information” has become a universal and omnipresent keyword in almost all areas of our modern world—be it in science or society in general. This is not only obvious from the naming of whole scientific branches like Information Theory, Information Science or Informatics but even more from common speaking—characterising our present time and society as information age viz. information society. However, what “information” might mean, is by no means clear and there is a wide range of interpretations covering, among others, its technical, communicational, educational, mental, and scientific aspects. But is the use of the same term justified when adopted in Biology, Physics, Archaeology, Law, Communication Technology, and Informatics (to list just a few of the involved scientific branches) or do its different uses at least have some common characteristics—some sort of common denominator? Is information natural, e.g. manifesting itself as a material phenomenon residing in organisms, stars, atoms, or genes, or is it just a cultural product of human communication, thinking, and interpretation? In this article, we try to clarify some of the most important interpretations, discuss and contrast them with the Informatics point of view. Interpretations range from taking information as material, transferable signals (following Shannon’s Information Theory or the genetic approaches), treating it as a sign (following a semiotic approach), as a commercial product (now common in Web-based Information Business) to considering it a pure mental phenomenon bound to humans or human-like individuals or even to groups and societies. Based on these interpretations, we shall throw a critical glance on current trends in human science and society—focusing on the now popular concept of “information society”—and then derive some theses and guidelines for further research escorting the growth and dispersal of information technology. As it will turn out, an information society which defines itself through the number of computers, internet connections and network links is based on a very narrow, techno-centric concept of information. However, a reflection on the educational and cultural aspects of information might lead to a better-qualified society consisting of responsible and critical citizens.  相似文献

This study is the first attempt to investigate the influence of unions on innovative activities in Germany at the industry level. Econometric models estimated by a highly robust method and submitted to a number of specification tests indicate that trade unions do not have a negative impact on innovative activity which is measured by either the percentage of revenues spent on R&D or the percentage of employees working in R&D. This finding is consistent with evidence on the influence of unions on productivity in Germany and with considerations about the German system of industrial relations.  相似文献

The aim of this article is to describe the extent of truancy in Cologne and to identify the relevant predictors. Hypotheses are deduced from classical deviance theories (control theory, amomy theory, theory of urban subcultures) and tested empirically. Our analysis is based on a survey of pupils in Cologne from grade 8 to 10 which was conducted in 1999 by the Max Planck Institute for Foreign and International Criminal Law in Freiburg. Our results show that 7.9 percent of all respondends can be defined as truants. Boys play truant more than girls, and the higher the age, the more pupils bunk off school. More important than gender and age is the type of secondary school. We find the highest amount of truants at Hauptschulen and Sonderschulen. It is shown that truancy is a multidimensional phenomenon that cannot be explained by just one single theory.  相似文献
