Abstract Background: Entrepreneurship is essential in creating, fulfilling and forming a healthy economy. This study is conducted to investigate Factor Affecting on Entrepreneurial Intention: The case study on Wollo University Students. Some studies have been done in this area but only a few were conducted in Ethiopia. This research aims to address the gap that exists due to the weakness of previous studies to verify the factors that affect entrepreneurial intention and provide more clarification on the topic. Methods: For the purpose of this study explanatory research design was employed. The researcher used stratified random sampling to classify all participants into seven colleges and one school of law. From each stratum proportionally by using purposive sampling to select 226 respondents with graduate students from college of business and economics for the desire of the study. Both primary and secondary data were collected. Primary data were collected through structured questionnaire from 210 students. Secondary data were collected from previous studies and used as reference. Results: The correlation and regression analysis has been applied to see the relationship and how independent variables influence entrepreneurial intention. From the analyses it is confirmed that demographic factors have statistically insignificant effect on entrepreneurial intention, while personal factors, environmental factors and family background have a statistically significant effect on entrepreneurial intention. Conclusions: Based on the findings it is concluded that demographic factor does not affect entrepreneurial intention while personal factors, environmental factors and family background affect entrepreneurial intention.

AbstractThe conventional data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) consuming multiple inputs to produce multiple outputs under the assumption that all the data are exact. In the real world, however, it is possible to obtain interval data rather than exact data because of various limitations, such as statistical errors and incomplete information, et al. To overcome those limitations, researchers have proposed kinds of approaches dealing with interval DEA, which either use traditional DEA models by transforming interval data into exact data or get an efficiency interval by using the bound of interval data. In contrast to the traditional approaches above, the paper deals with interval DEA by combining traditional DEA models with error propagation and entropy, uses idea of the modified cross efficiency to get the ultimate cross efficiency of DMUs in the form of error distribution and ranks DMUs using the calculated ultimate cross efficiency by directional distance index. At last we illustrate the feasibility and effectiveness of the proposed method by applying it to measure energy efficiency of regions in China considering environmental factors.

Shared Psychotic Disorder

Shared psychotic disorder, characterized by shared delusion among two or more subjects (termed “Folie à deux,” “trois,” etc.), is often associated with strong religious beliefs or social isolation, factors creating strong psychological sympathy. Recently, we treated a rare familial case of “Folie à quatre” in central Tokyo without such influences. The proband was a schizophrenia patient and younger brother within monozygotic twins. Positive symptoms were “transmitted” to remaining family members, his elder brother, mother, and father father, in a relatively short period of three months. Although the pathophysiology of these positive symptoms (delusions and hallucinations) remains unclear, the transmission pattern suggests the primacy of social and environmental factors (and/or their interaction), while genetics appeared less influential in this “Folie à famille.” Although undiagnosed psychoses in the whole family cannot be excluded, they did not share the other negative schizophrenia symptoms of the proband. A strong familial connection appeared to be the most important factor for the common delusion and hallucination.

Tobacco use is one of the most preventable causes of premature death globally, yet statistics show that there has been an increase of female smokers. Hence a need to understand why smoking prevalence continues despite the overwhelming data on adverse health effects. The aim of this study was to explore personal, socio-cultural, and environmental factors that are associated with smoking among female university students of University of Lusaka. A qualitative case study design was conducted with a sample 12 female students from the University of Lusaka. Snowball sampling was utilized. Female students smoking tobacco were predominantly associated with the desire for personal gratification, to feel accepted by their peers who smoke, to express female independenceand freedom and exposure to a male family member who smokes at younger age. Socio-cultural factors such as such as peer influence, family influence and female modernity in society were the major influencers of smoking in the female students, and environmental factors such as the lack of responsiveness to Zambia’s anti-smoking campaigns and a gap in the enforcement of anti-smoking legislation in Zambia also played an indirect role in facilitating smoking among female student. Anti-smoking campaigns could try and consider evaluating interventions from a male and female perspective respectively.

This study aims to determine the effectiveness of implementing Law Number 23 of 2004 on Elimination of Violence in Household, as well as the factors that influence its enforcement. This type of research is empirical legal research with a quantitative descriptive in nature. This research was conducted in Makassar City to be precise at the Makassar City Police. The data collection techniques used in this study were questionnaires, documentation, and literature study. The data analysis technique used is quantitative data analysis techniques. The results showed that the implementation of Law No. 23 of 2004 in Makassar City is still considered less effective. Factors affecting the effectiveness of the implementation of Law No. 23 of 2004 in Makassar City consists of several factors, namely: legal factors; law enforcement factors; supporting facility factors; environmental factors; and cultural factors. in addition, environmental factors are the biggest factor affecting the effectiveness of the implementation of Law No. 23 of 2004.
