Abstract

The present study addresses the consequences of materialistic value-orientation (i.e. Acquisition Centrality) on the effect of the sense of control on religious experiences of the urban consumer class of Bangladesh. The central thesis is that economic transformation may contribute to the materialistic value-orientation and exert a control on the social experience; nonetheless, it would not exert any effect between the relationship of the Locus of Control and the role of religion. To test the thesis, the research investigates; given the economic growth begets acquisition centrality on a larger scale and these values, in return, often form the new purpose of social lives and emerge as a potential social force of modernity. Can religion as a century-old social institution continue to have strong-hold on the definition of social reality? To answer the question, this Cross-sectional research administered a survey of 1246 respondents from ten randomly selected distinct areas of Dhaka city and analyzed the data within a structural equation modeling (SEM) framework. The findings suggest that the people with high (External) sense of control are more likely to be influenced by their religious experiences and the people with low (Internal) sense of control have high Acquisition Centrality; Acquisition Centrality strengthened the influence of External Locus of Control on the influence of religion.

Abstract

Evidence from literature shows that deviant behavior is on high side among undergraduates in Nigeria whereas some certain psychosocial factors causing this phenomenon have not been fully explored. This study examined whether age, gender, socio-economic status and attitude towards drug abuse determine deviant behavior among the undergraduate students. It adopted ex-post facto design. Simple random sampling technique was used to sample 269 participants. The Prescription Drug Attitudes Questionnaire (PDAQ) and Deviant Behavior Variety Scale (DBVS) were used to gather data from the participants. T-test analysis and multiple regression were used to test the formulated hypotheses. The results revealed that age, monthly allowance and attitude towards drug abuse have significant joint prediction of deviant behavior (R=.358 R2 =.128, F=10.594, p<.05) while only attitude towards drug abuse independently predicted deviant behavior (R=.236, R2 =.056 F = 17.112; p<.01). Also, there was a significant gender difference on deviant behavior [t (293) = 4.196, p<.01], where male respondents scored high significantly (M=4.09, SD=3.44) compared to female respondents (M=2.53, SD=2.31) on deviant behavior. It is therefore recommended that policy makers in educational sector and the governing council of tertiary institutions need to create awareness on the debilitating effects of drugs on students’ behavior, especially among males.

Abstract

The present paper has identified two career models, the Protean Career and the Boundaryless Career, that can be considered to accommodate higher education graduates’ personal and professional needs, as well as the flexibility and adaptability requirements of the current labor market. The research used the data from a tracer study applied online to the graduates of the West University of Timisoara, with a response rate of 25% (which falls within the response rate for similar studies at the European level).

There has been an increased dynamic of the number of jobs compared to the short period since they have been active on the labor market, especially among male graduates. At the level of individual factors that can influence career success, the importance given to both objective and subjective values is observed. The results have shown that for graduates, income, job security, the possibility of promotion, the use of knowledge, but especially leisure time, are equal priorities, with consistent values in time for both stages of the study. Moreover, there has been a significant negative association between the variables of leisure time and job satisfaction (r (522) = -.17, p <.001). Given the mode of action, the high dynamics of jobs, which reflect the much-needed flexibility in the dynamic context of the labor market, and the values that have guided job search, often working and studying at the same time, the pattern of employment career that most accurately describes the career profile of graduates seems to be that of the Protean career (the path with a heart), also called the career of the 21st century.

Abstract

The problem of selecting an optimal set of investment stocks is of a huge interest for both individual and institutional investors. This paper compares the hybrid multiple criteria decision making (MCDM) approach to selecting the best stock to invest in, with the stock selection using modern portfolio theory (MPT). When selecting stocks, it is very important to thoroughly analyse stocks, according to multiple criteria, including their equity market indicators, as well as financial indicators. The objective of the research is to compare the stock selection using a hybrid MCDM approach and MPT, which includes only the equity market indicators. The analysed sample includes 18 stocks, which are CROBEX components on the Croatian capital market from January 2017 to January 2019. The rankings of stocks were calculated using five MCDM methods. These were then used to obtain the final hybrid stock ranking, which was compared to the MPT stock selection. The results show that there is a significant difference in the stock rankings. However, the stocks which have not entered any portfolio in MPT selection were ranked as lowest according to the hybrid MCDM approach, which confirms that those stocks are the worst to invest in. The research can serve as a guidance for investors to use all available stock information in their decision making process of investment.

Abstract

The main objective of this analysis is to evaluate and compare the various classification algorithms for the automatic identification of favourable days for intraday trading using the Croatian stock index CROBEX data. Intra-day trading refers to the acquisition and sale of financial instruments on the same trading day. If the increase between the opening price and the closing price of the same day is substantial enough to earn a profit by purchasing at the opening price and selling at the closing price, the day is considered to be favourable for intra-day trading. The goal is to discover relation between selected financial indicators on a given day and the market situation on the following day i.e. to determine whether a day is favourable for day trading or not. The problem is modelled as a binary classification problem. The idea is to test different algorithms and to give greater attention to those that are more rarely used than traditional statistical methods. Thus, the following algorithms are used: neural network, support vector machine, random forest, as well as k-nearest neighbours and naïve Bayes classifier as classifiers that are more common. The work is an extension of authors’ previous work in which the algorithms are compared on resamples resulting from tuning the algorithms, while here, each derived model is used to make predictions on new data. The results should add to the increasing corpus of stock market prediction research efforts and try to fill some gaps in this field of research for the Croatian market, in particular by using machine learning algorithms.

Abstract

Let 𝒯( k ) n denote the set of k-Stirling permutations having n distinct letters. Here, we consider the number of steps required (i.e., pushes) to rearrange the letters of a member of 𝒯( k ) n so that they occur in non-decreasing order. We find recurrences for the joint distribution on 𝒯( k ) n for the statistics recording the number of levels (i.e., occurrences of equal adjacent letters) and pushes. When k = 2, an explicit formula for the ordinary generating function of this distribution is also found. In order to do so, we determine the LU-decomposition of a certain infinite matrix having polynomial entries which enables one to compute explicitly the inverse matrix.

Abstract

European countries interest for archaeological heritage, as part of the cultural landscape, was firstly expressed at the London Convention (1969), whose content was later revised by La Valetta Convention (1992). Romania joined this Convention in 2000, thus assuming the mission to protect and preserve the archaeological heritage, facing with massive economic development and urban expansion. Although we speak of a consecrated historical center, in Timisoara’s urban landscape preventive archaeology has become a reality only from 2004, when first researches were conducted. During the last few years, local infrastructure development has determined an extension of archaeological investigations over the historical area of the city, with major influences especially over public transportation (most of the times hampered, sometimes deviated, even blocked in the specific area, during archaeological research). Our approach focuses on multiple facets and implications of preventive archaeology over Timisoara’s urban landscape, from immediate, obvious issues (such as population’s satisfaction regarding archaeological investigations, their consequences (over access in the area, safety or transportation)), to long-term results (over local tourism, urban development or locals’ education for protecting and promoting cultural heritage).

Abstract

Alcohol use among students in tertiary institutions has long been established as a major public health concern. Also, previous research has shown that individuals with depression are particularly susceptible to alcohol use. There is, however, a paucity of empirical studies focusing on whether this relation is moderated by gender or buffered by a sense of inner meaning fulfilment. We assessed the moderating roles of gender and inner meaning fulfilment in the relationship between depression and alcohol use among university students in Nigeria. A correlational survey design was utilized. Data were collected from 1,173 students (57% male) aged between 16 and 36 years selected across six Nigerian universities. Data were subjected to SPSS v.23 for statistical analysis. Our findings show that depression, gender, inner meaning fulfilment significantly correlated with alcohol use. The effect of depression on alcohol was positive and significant (b=.439, se=.049, p=.000). Inner meaning fulfilment significantly moderated the relationship between depression and alcohol use (b=-.163, se=.034, p=.000). Depression was established as a significant risk factor for alcohol use, regardless of gender, and inner meaning fulfilment may buffer this association. Implications and recommendations are discussed.
