Political scientists generally derive their quantitative methodologies from two disparate traditions: econometric or psychometric. The psychometric tradition has made a lasting impact on political analysis through attention to issues of measurement. Measurement issues are particularly troublesome to political scientists because many interesting concepts are either latent or multidimensional. On the other hand, the econometric tradition has provided political scientists with a means of coping with macrolevel phenomena. In studying macrophenomena, the problem of few cases (there is only one American economy, for example) is handled by using longitudinal analysis. Econometrics provided tools for coping with challenges that longitudinal analysis posed for regression analysis.

The present study aimed to measure the link between representations of money, ethnolinguistics affiliations and the nature of corruption among agents and users of public services. The numerous legal mechanisms put in place have produced limited results without big effects. Thus, this survey raises the problem of the persistence (obstinacy) of corruption in spite of the multiple efforts taken various levels (institutional, national, and international). The sample of the study consists, on the one hand, of 100 users of public services chosen at random at the Directorate of Treasure and Public Accounting (DGTCP) and at the General Directorate of Taxes and Domains (DGID) in Benin. And on the other hand, of 50 agents in public service; identified in the two directorates according to their contact with the users in the exercise of their functions. Two different questionnaires were used to collect data on the two targets (of agents). The results from the correlation and regression analysis confirm the existence of a significant link between the representation of money, ethnolinguistics affiliations of the agents and users of public services and the behavior of corruption. The results of this research will allow authorities at various levels to better understand the behavior of corruption of the agents and users of public service and it will also be of use in the drafting of measures that aim at changing people’s behavior for an effective and productive fight against corruption.

Bicycle-sharing programs have emerged around the world. Theoretically, the effect of bicycle sharing on more conventional transit modes can take a substitute or complementary form. On one hand, bicycle sharing could substitute for conventional transit as a convenient and sustainable travel option. On the other hand, bicycle sharing may complement such transit by seamlessly connecting transit stations with origins and destinations and thus increase accessibility. However, the questions of how and to what extent bicycle-sharing programs affect public transit ridership remain to be answered, despite the attempts of a few empirical and quantitative studies. This study examined the impact of the Capital Bikeshare (CaBi) program on Metrorail's ridership in Washington, D.C. When CaBi trips were mapped, it was observed that Metrorail stations had been important origins and destinations for CaBi trips. Six of seven CaBi stations producing more than 500 trips were located close to Metrorail stations. This study conducted a regression analysis and found that public transit rider-ship was positively associated with CaBi ridership at the station level. A 10% increase in annual CaBi ridership contributed to a 2.8% increase in average daily Metrorail ridership. On the basis of these results, policy implications and recommendations are discussed.

The research seeks to investigate students rating of various forms of academic dishonesty and also examined the impact of psychological gender on cheating behavior among undergraduates in a Malaysian university. Primary data were sourced through the distribution of 363 questionnaires. Statistical analysis of the data revealed that the following cheating techniques have widely used them a. Using published materials without reference, copying the assignments, using unfair means for presenting data, getting unauthorized help for assignment completion and presenting others work. On the other hand, regression analysis on the psychological gender revealed that the instrumental traits tend to influence male to engage in academic dishonesty.

AbstractThe analysis presents some of the results of an online survey regarding the COVID-19 pandemic, which was undertaken among ethnic Hungarians from Transylvania. The survey was based on a convenience sample and was realized between 16 and 26 April 2020, so during a specific period of the lockdown. Among others, the questionnaire asked the respondents about the degree in which the post-pandemic world would change. The answers to the question show that nearly three quarters of the respondents think that the world will not change at all or it will suffer only minor changes. Those who are more prone towards seeing a totally or a majorly changed world are in a minority. We assume that this situation could reflect a wishful thinking in front of an uncertain context. The regression analysis showed that respondents’ opinion regarding the change can be only marginally predicted by the selected independent variables. Men, those holding materialistic values, are significantly less convinced that the world will suffer major/total changes. On the other hand, trust in several institutions raises the odds of formulating the opinion that the post-pandemic world will be considerably changed.

The relation of extra-embryonic fluid weight to litter number and foetal and placental weight was studied in mice on the 18th day of pregnancy, in litters both of experimentally reduced and of normal number. Partial regression analysis showed that litter number and foetal weight both exerted a negative effect on fluid weight; placental weight had no significant effect. Increased foetal weight reduced weight locally; on the other hand the effect of litter number was exerted systemically, throughout both horns of the uterus.

Abstract. α-MSH, ACTH and β-endorphin were measured by radioimmunoassay in samples of amniotic fluid collected from the 32nd to the 38th gestational week and at labour from normal pregnancies and pregnancies complicated by gestosis. In normal pregnancies, the concentration of α-MSH, ACTH and β-endorphin remained relatively constant during the last 7 gestational weeks, but increased at labour above the values of the 38th week by 88, 143 and 96%, respectively. A positive correlation between β-endorphin and α-MSH (r=0.92) or ACTH (r=0.76) levels was found when labour values were considered in the regression analysis. In contrast, when labour values were excluded, only a poor positive correlation between β-endorphin and α-MSH (r=0.52) was found. In complicated pregnancies, α-MSH and ACTH concentrations were similar to those found in normal pregnancies; on the other hand, the level of β-endorphin, was found to be 130% higher than normal. As in normal pregnancies, α-MSH, ACTH and β-endorphin levels increased at labour, but only by 46, 44 and 23%, respectively. In contrast to in normal pregnancies, the correlation between β-endorphin and α-MSH or ACTH was not significantly modified by labour values. The present results confirm and extend previous studies showing that β-endorphin may be considered a marker of fetal distress and that the fetal pituitary is capable of reacting to stressful stimuli in normal and suffering fetuses.

An experiment was conducted with college students to examine the effects of source and user comments on the perceptions of a shared news story embedded in a blog post. When the shared news was credited to a news organization source incongruent with the participants’ political orientation, it was perceived to be biased against the participants’ issue position. When credited to a congruent source, the same news was perceived to be biased in favor of the participants’ position. In addition, the shared news from an incongruent source was perceived to have greater influence on others’ issue position than the same news from a congruent source, although perceived reach of the shared news was not different between the two conditions. A subsequent regression analysis identified source and perceived influence, but not perceived reach, as predictors of news bias perception. On the other hand, the second factor, user comments either agreeable or disagreeable to the participants’ issue position, did not influence how the shared news was perceived. In the discussion, theoretical implications of these findings are elaborated, and suggestions are made to refine the methods of shared news research.
