The main purpose of this study is to examine the effects of health workers’ levels of work commitment on the levels of depression and burnout.  Having this purpose in mind, a questionnaire consisting of personal information form, work commitment scale, burnout scale and depression scale was conducted with 266 health workers of İstanbul Kartal Training and Research Hospital in May 2013. Data obtained from questionnaires were analyzed by SPSS 17,0 statistical software. Correlation analysis was utilized in order to determine the relationships among work commitment, burnout and depression levels of health workers whereas regression analysis was utilized in order to determine the effects of health workers’ levels of work commitment on the levels of depression and burnout. According to the results, it has been found that there are statistically relevant relationships among work commitment, burnout and depression levels of health workers. It has been concluded that the more health workers’ levels of work commitment increase, their levels of depression and burnout decrease.

Bevezetés: A neonatális szepszis mortalitása magas, és koraszülöttek esetén a szepszis rizikója emelkedik a születési súly csökkenésével. Anyag és módszer: A szerzők gyorsteszt segítségével 12 érett újszülött és 60 igen kis súlyú (VLBW) koraszülött interleukin-6-vérszintjét határozták meg a C-reaktív protein vizsgálatával egyidejűleg, akiket a Semmelweis Egyetem I. Számú Szülészeti és Nőgyógyászati Klinikájának Neonatális Intenzív Centrumában kezeltek 2005-ben és 2006-ban. A szérum-IL-6 meghatározása gyorsteszt segítségével történt (Milenia Quickline IL-6, PicoScan system). Eredmények: Vizsgálataikban a szérum-interleukin-6- és CRP-meghatározás korrelált. A szérum-IL-6-meghatározás szenzitivitása a CRP-értékkel együtt az általuk vizsgált betegcsoportban 100% volt, álnegatív eset nem fordult elő. A vizsgálat pozitív prediktív értéke 93%. Adataikat Mann–Whitney-teszt segítségével analizálták (SPSS Statistical Software Package, Chicago, IL, USA). Szignifikáns különbség volt az igazolt szepszis és az infekciós betegcsoport IL-6-értékei között ( p = 0,048), valamint az infekciós és nem infekciós csoport interleukin-6-értékei között ( p < 0,005). Következtetések: Az igen kis súlyúak nem specifikus infekciós tünetekhez hasonló reakcióit értékelve, a szeptikus és nem infekciós esetek elkülönítése a neonatális morbiditás és mortalitás csökkentése érdekében is fontos szempont, a költségek csökkentésével egyidejűleg.

Unemployment is one of the economic problems in Indonesia. Judging from the level of education that was completed there were unemployment from the level of college graduates. This encourages the level of competition in getting jobs to be more stringent, so that college graduates (bachelor of Statistics in IPB) must have the preparation of various factors to maintain the quality of their graduates. The quality of college graduates can be seen from the length of time waiting to get a job. This study aims to determine the influential factors in getting a job for graduates of the IPB Statistics degree, so that the CHAID method can be used in this study. The results of CHAID's analysis in this study in the form of tree diagrams using α = 10% explained that the factors influencing the waiting period variables were sex, internship, and the ability to master statistical software, where the accuracy value generated by the classification model was 79.3 %.

Although extensively studied, psoriasis still has negative consequences and is associated with multiple comorbidities, including metabolic syndrome. The severity of psoriasis seems to influence the occurrence of diagnostic criteria for metabolic syndrome. 208 patients diagnosed with psoriasis were identified, who were divided into lots depending on the severity of psoriasis, but also to the presence or absence of metabolic syndrome. Interpretation of statistical data was done with SPSS V21 (Statistical Package for Social Science) and MEDCALC (Statistical Software). The coexistence of severe psoriasis with metabolic syndrome increases the risk of developing cardiovascular diseases by 2.97 or greater, with a confidence interval of [1.60, 5.51], than that of patients with severe psoriasis who have no metabolic syndrome. The hypothesis was statistically confirmed by p = 0.003. Analyzing the total group with psoriasis by severity, we found the following distribution: from the total number of 208 patients, 39 (18.8%) had severe psoriasis, 83 (39.9%) moderate psoriasis and 86 (41.3%) mild psoriasis. The higher incidence of metabolic syndrome in patients with psoriasis is evidenced by the Pearson Chi-Square test, where p [0.001. The association of metabolic syndrome in patients with psoriasis is evident. The more severe the psoriasis, the more likely it is to develop metabolic syndrome.

The main purpose of this study is to examine the effect of corporate social responsibility on the organizational performance of the Dangote cement factory in Ethiopia. In order to achieve the research objectives, the authors adopted both a descriptive and explanatory research design. Structured questionnaires were used to gather data from the targeted group of the study, where the probability and non-probability sampling technique was employed to draw a sample of 179. The collected data were presented and analyzed using the SPSS (version 20) statistical software package. A multiple linear regression model was applied to see the effect of CSR on organizational performance. The study showed that philanthropic activities, ethical activities, and legal activities affect organizational performance, have a positive relationship, and are statistically significant at a 1% confidence interval. It was concluded that for the existence of business industries, the community relation is key to ensuring a conducive atmosphere for the business to succeed.

Item Response Theory Models

In this article, we present StataStan, an interface that allows simulation-based Bayesian inference in Stata via calls to Stan, the flexible, open-source Bayesian inference engine. Stan is written in C++, and Stata users can use the commands stan and windowsmonitor to run Stan programs from within Stata. We provide a brief overview of Bayesian algorithms, details of the commands available from Statistical Software Components, considerations for users who are new to Stan, and a simple example. Stan uses a different algorithm than bayesmh, BUGS, JAGS, SAS, and MLwiN. This algorithm provides considerable improvements in efficiency and speed. In a companion article, we give an extended comparison of StataStan and bayesmh in the context of item response theory models.
