Background Lifestyle choices reflect the beliefs that individuals attribute to aspects of life. This construct can be assessed with the Individual Lifestyle Profile (PEVI) questionnaire, which measures elements of Nutrition, Physical Activity, Preventive Behaviors, Social Relationships and Stress Management. Objective The objective of this study was to estimate the psychometric properties of the PEVI applied to a sample of Brazilian university students, identifying the prevalence of each lifestyle component according to participants’ age, sex, weight status, course area/field and economic stratum and to estimate the contribution of these characteristics on physical and psychological lifestyle. Methods The PEVI data was analyzed by confirmatory factor analysis, using the indexes chi-square per degrees of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI) and Root Mean Square Error of Approximation (RMSEA). First-order and second-order models (physical and psychological lifestyle) were tested. Prevalences of lifestyle components were calculated and compared by participants’ age, sex, weight status, course area/field and economic stratum. A hypothetical causal structural model was elaborated to investigate the impact of sample characteristics on physical and psychological lifestyles. This model was evaluated considering the global fit to the data (χ2/df, CFI, TLI and RMSEA) and the hypothetical causal trajectories (β) (α = 5%). Results A sample of 1,303 students was used. The mean age was 20.9 (standard deviation = 2.8) years, 66.8% of participants were females, 63.4% had weights in the normal range and 73.7% were students of the social and exact sciences. The PEVI data showed an adequate fit for both the first- (χ2/df = 2.03, CFI = 0.98; TLI = 0.97; RMSEA = 0.04) and second-order (χ2/df = 2.25; CFI = 0.97; TLI = 0.97; RMSEA = 0.04) models. There was a higher prevalence of unfavorable physical and psychological lifestyle choices among females, among underweight and obese individuals, in older students and in those with lower economic strata. Moreover, negative behaviors in physical lifestyle were more prevalent in students from human/social/exact sciences and worse psychological lifestyle was observed among health sciences students. These results were confirmed by a structural model. Conclusion The PEVI data presented validity and reliability. Negative lifestyle choices had high prevalence among students. Moreover, individual characteristics had different impact on physical and psychological lifestyle choices.

The Relationship

In this study we proposed to estimate the impact of lifestyle, negative affectivity, and college students’ personal characteristics on eating behavior. We aimed to verify that negative affectivity moderates the relationship between lifestyle and eating behavior. We assessed eating behaviors of cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE)) with the Three-Factor Eating Questionnaire-18. We assessed lifestyle with the Individual Lifestyle Profile, and we assessed negative affectivity with the Depression, Anxiety and Stress Scale-21. We constructed and tested (at p < .05) a hypothetical causal structural model that considered global (second-order) and specific (first-order) lifestyle components, negative affectivity and sample characteristics for each eating behavior dimension. Participants were 1,109 college students ( M age = 20.9, SD = 2.7 years; 65.7% females). We found significant impacts of lifestyle second-order components on negative affectivity (β = −0.57–0.19; p < 0.001–0.01) in all models. Physical and psychological lifestyle components impacted directly only on CR (β=−0.32–0.81; p < 0.001). Negative affectivity impacted UE and EE (β = 0.23–0.30; p < 0.001). For global models, we found no mediation pathways between lifestyle and CR or UE. For specific models, negative affectivity was a mediator between stress management and UE (β=−0.07; p < 0.001). Negative affectivity also mediated the relationship between thoughts of dropping an undergraduate course and UE and EE (β = 0.06–0.08; p < 0.001). Participant sex and weight impacted all eating behavior dimensions (β = 0.08–0.34; p < 0.001–0.01). Age was significant for UE and EE (β=−0,14– −0.09; p < 0.001–0.01). Economic stratum influenced only CR (β = 0.08; p = 0.01). In sum, participants’ lifestyle, negative emotions and personal characteristics were all relevant for eating behavior assessment.

The Impact

Consensual union, also known as cohabitation, has become more frequent in recent decades in Brazil and many other countries. In this context, some studies have analyzed the impact of marriage on women's wages. This article analyzes the effects of marital status on Brazilian women's wages by specifically investigating the individual characteristics of these effects using data from the 2000 Brazilian Census Database. This study concludes that wages differ by up to 15 per cent between married and single women and up to 3 per cent between married and cohabiting women.

The Impact

The use of open-plan offices is increasing as they are effective in improving intellectual productivity by fostering a communication among workers. Previous research on the relationship between the indoor sound environment and intellectual productivity has mostly reported the impact of the sound environment on the tasks that individuals work on. However, there has been no research on the impact of sound environment on office spaces where multiple workers are actually working. In this study, we developed a system that can analyze the individual characteristics of workers in relation to the sound environment by simultaneously measuring their evaluation to the sound environment and the sound environment of the office. The system collected workers' evaluation of their impressions to the sound environment through a regular questionnaire using the experience sampling method. At the same time, it measured the sound environment of the office with multiple small measurement devices. The obtained sound environment evaluation data and the acoustic data of the office were stored in a single database. Finally, this system was run in a working environment to evaluate the sound environment on a trial basis.

AbstractThe effect of heated waters from coal-burning power stations on the water parameters and the occurrence of macroinvertebrates depends on the individual characteristics of the river to which the heated waters are discharged. The objective of the study was to assess the impact of heated water from the Ostrołęka Power Station on selected water properties and the macroinvertebrate community in the Narew River. Samples were collected in years: 2013-2016 along two river stretches: upstream and downstream of the canal. The water temperature was higher and the oxygen concentrations were lower at the downstream sites compared to the upstream sites of the canal. The values of conductivity, concentrations of nitrates, phosphates, chlorides and calcium were similar at the sampling sites. A total of 33 families of macrozoobenthos were found. The numbers of families were positively correlated with the temperature and conductivity and negatively correlated with oxygen. The heated waters were found to have no effect on the Shannon-Wiener diversity index. The inflow of heated waters increased the percentage of Gammaridae, represented by species Dikerogammarus haemobaphes (Eichwald, 1841) and decreased the percentage of Chironomidae. The presence of the thermophilous bivalve Sinanodonta woodiana (Lea, 1934) was noted downstream of the canal.

The Impact

Scholars and governments are interested in four sets of questions concerning public opinion on foreign policy and national security policy. First, what do public opinion polls measure? How do citizens, who are generally uninformed about foreign policy and world affairs, form opinions on these matters? Second, how rational is public opinion? Is it stable or volatile? Are opinions coherent? Do opinions plausibly reflect the flow of world events? Third, what factors influence the formation of citizen opinions? Specifically, what is the impact of fundamental attitudes toward war and military force, partisanship, ideology, and gender? Finally, how universal are the determinants of citizen opinion, especially on crucial issues of war and peace? Are the findings in global comparisons the same as those in the American or European contexts? Considerable scholarship has been devoted to these four questions. Scholars now characterize public opinion as rational, in the sense that it is fairly stable, coherent, and responsive to real world events. Attitudes toward war and military force are a major focus of the research literature because many specific policy attitudes flow from fundamental views of war. Gender has also become a major focus of research because many studies find that women are less supportive of the use of military force for most purposes. Finally, scholars are beginning to discover that some opinion patterns are universal across societies, while others are more affected by the individual characteristics of national societies. Studies of global public opinion have expanded greatly, with recent scholarship focusing on global attitudes toward gender equality, immigration, and climate change.

The Impact

Studies on female legislative behavior suggest that women parliamentarians may challenge party cohesion by allying across party lines. In this paper we analyze a specific parliamentary activity – bill co-sponsorship – in the Italian lower Chamber, between 1979 and 2016, as a source of information about MPs’ original preferences to study how gender affects party cohesion. Do women form a separated group in the Italian parliament? On average, are they more or less distant from the center of their parties than men? Does gender affect systematically party cohesion? A principal component analysis of co-sponsorship data allows us to identify the ideal points of all MPs in a multidimensional space for each legislature. Based on these data we estimate the impact of gender on party cohesion at the individual level while controlling for the impact of several other variables of different kind (individual, partisan, and institutional). We find that: (1) on average, women show lower cohesion as a group inside different parties and higher party cohesion than men; (2) the influence of gender on party cohesion is not conditional upon individual characteristics, upon the size and organization of parliamentary parties, and upon the share of women in their parliamentary groups; (3) the different behavior of women MPs may depend on the different patterns of recruitment in the parties.

ABSTRACTThis study examined the impact of situational and individual characteristics on sales representatives' propensity to lie or to tell the truth. The situational elements were the honesty of the organisation climate and its formal rules about lying to customers. The individual elements were the participants' degree of Machiavellianism and tolerance for ambiguity. The results indicated that more Machiavellian people were more likely to lie and that they were less guided by the rules than people who were low in this trait. In addition, rules and climate work together for people with a high tolerance for ambiguity in a complex manner.

The Impact

The article devoted to one of the topical problems of penitentiary institutions – the return to society of a prisoner who has served a sentence, provided that he or she will never commit crimes. This is the most difficult problem that arises in the course of the implementation by the penitentiary system of its main function – to ensure the safety of society. In many countries, the degree of prisoners’ isolation is determined by their categorization. German practice is based on a risk assessment of illegal conduct in relation to a particular person. The risk of violent acts is not necessarily related to the nature of the committed crime or the length of the sentence. The prison administration makes its own decision on the choice of the regime of detention. The penitentiary system (not the court) develops flexible security measures that can be changed in relation to the prisoner’s personality. All measures taken against prisoners should be based on the proportionality principle. The analysis of various rehabilitation programs for prisoners, used in Western Europe, leads the author to the conclusion that the most effective of them is individual therapy, which reduces the risk of recidivism by almost half. As a standard used in Germany, the author specify the principle of “risk – need – quick res-ponse”. The higher the risk of recidivism, the more intense the impact on the prisoner’s behavior should be. However, the application of this principle will be effective only when the selected cognitive techniques and practical training technologies coincide with the individual characteristics and the prisoner’s ability to learn. In addition, the results achieved by the prison administration must be supported by post-penitentiary rehabilitation programs. The article also describes the system of selection and training of prison personnel in Germany.

Creative Team

Rather than the view of the entrepreneur as a ‘lone ranger’, recent work has focused on the importance of teams in bringing a start-up to growth and success. Here, we aim to bridge the gap between the individual characteristics of entrepreneurs and the characteristics of their teams by examining openness of founders in relation to creative team environment (CTE), innovative work behaviour (IWB) and performance. On the basis of upper echelon theory and integrating other complementary theories such as the attention-based view, we develop a theoretical framework and test this using a survey of 322 high-tech entrepreneurs. Our findings suggest a mediating role of CTE and IWB in the relation between openness of entrepreneurs and performance. The implications of the results for managerial practices and future research directions are discussed.

The study presents an algorithm, ParSCAPE, for model-independent extraction of peak positions and intensities from atomic pair distribution functions (PDFs). It provides a statistically motivated method for determining parsimony of extracted peak models using the information-theoretic Akaike information criterion (AIC) applied to plausible models generated within an iterative framework of clustering and chi-square fitting. All parameters the algorithm uses are in principle known or estimable from experiment, though careful judgment must be applied when estimating the PDF baseline of nanostructured materials. ParSCAPE has been implemented in the Python programSrMise. Algorithm performance is examined on synchrotron X-ray PDFs of 16 bulk crystals and two nanoparticles using AIC-based multimodeling techniques, and particularly the impact of experimental uncertainties on extracted models. It is quite resistant to misidentification of spurious peaks coming from noise and termination effects, even in the absence of a constraining structural model. Structure solution from automatically extracted peaks using the Liga algorithm is demonstrated for 14 crystals and for C60. Special attention is given to the information content of the PDF, theory and practice of the AIC, as well as the algorithm's limitations.
