The purpose of this research is to evaluate ethnicity and its impact on the political structure of Punjab, Pakistan. This topic was required by the subverting tendencies of the circumstances that, in reality, endanger the survival of the minority groups in Punjab. In order to upgrade provincial political development, the facets that proliferate its existence in policies and hold it can be abolished. They have not yielded any efficacious outcomes in spite of elucidation that has been consistently provided. Subsequently, they need to search for a more practical alternative by focusing on the divisions that are present in ethnic societies. Ethnic democracy should be present that is a governmental system that links the ethnic groups to their democratic and political rights. Quantitative research was used in this research article. The researcher collected the data by distributing questionnaire among people. For future research, this research concludes with a debate of recommendations.

Purpose The purpose of this paper is to identify and theoretically explain the general barriers to adopting lean construction practices in the construction industry regardless of the country or the company size or specialization, and to suggest future research studies in this field. Design/methodology/approach Systematic literature review was conducted to identify and explain the list of the barriers from scientific sources that were published before May 2018. Findings Twenty-nine barriers were identified and explained, and a proposed model to classify the sources of the barriers was chosen. Seventeen barriers were classified as internal environment-related barriers, five were labor-related, three were materials-related and four were exogenous barriers. In addition, some directions for the future research studies were suggested. Research limitations/implications The barriers that are related to the advanced levels of lean construction (LC) implementations, to a specific location or to a specific LC tool were excluded. Originality/value This review will help to increase the understanding of the new concept of LC and might help to encourage the adoption of LC practices. Also, it might be useful for identifying the strategies to achieve successful application of these practices.

Q-methodology is a technique incorporating the benefits of both qualitative and quantitative research. Q-method involves Q-sorting, a method of data collection and factor analysis, to assess subjective (qualitative) information. The use of Q-sorting and factor analysis has often resulted in the misconception that Q-methodology involves psychometric or quantitative assessment, although Q as a methodology actually enables the systematic assessment of qualitative data. Misconceptions regarding Q have resulted in a heterogeneous collection of Q-applications in the extant literature, which has obscured the fundamental principles of Q-methodology. The purpose of this paper is to present a systematic review of Q-based research to investigate the criteria researchers have used to develop Q-studies. Published research studies between January 2008 and December 2008 that employed Q-techniques and methodology were assessed. Data were extracted and synthesized through the development and use of the Assessment and Review Instrument for Q-methodology (ARIQ). Fourteen research studies met the inclusion criteria for the review. The Q-methodological studies were disparate in their application of terminology, instrument development, and factor analysis, although data extraction and synthesis processes revealed two types of studies: those which aimed to apply conventional Q-methodology and those which applied variations of Q-techniques. It is concluded that variations of Q-technique and its methodology are unavoidable. However, this does not obviate the need for researchers to explicitly state their rationale for decisions to deviate from conventional Q-methodology if they are to produce demonstrably valid research. The review instrument (ARIQ) developed for this review will facilitate this end.

In the past twenty years there has been a surge of research on chemistry students’ attitudes, self-efficacy, self-concept, expectations, values, interest, motivation, effort beliefs and achievement emotions. This research has sought to understand how students feel when learning chemistry and how this may be influencing how they perform. However the wealth of this research has yet to be reviewed as a whole to identify its major themes and findings. This article reports on a review of 91 affective chemistry education research studies published since the year 2000. A focus of this review is to survey the methodological approaches used throughout research. The main finding of this review is that quantitative research regimes overwhelmingly dominant the landscape of affective chemistry education research. Of the studies reviewed, 85% (n = 77) are quantitative, 10% (n = 9) are mixed-methods while just 5% (n = 5) are qualitative research studies. Five overarching themes of affective chemistry education research are revealed. These themes manifest as the purposes behind these research studies which include; (i) to measure and compare affective states across various student demographics and contexts (32%, n = 29), (ii) to assess the influence of a learning intervention on student affect (30%, n = 28), (iii) to correlate measured affective states to performance in exams (24%, n = 22), (iv) to develop and validate scales for chemistry education research (10%, n = 9) and (v) to quantitatively model affective theoretical frameworks (3%, n = 3). The dominance of quantitative research regimes to investigate student affect may be challenged given the highly subjective and unstable nature of measured affective states. The findings of this review offer a series of implications for affective chemistry education which will be later discussed with a view to indicating potential directions for future affective chemistry education research.

In addition to qualitative methods presented in chaos and complexity theories in educational research, this article addresses quantitative methods that may show potential for future research studies. Although much in the social and behavioral sciences literature has focused on computer simulations, this article explores current chaos and complexity methods that have the potential to bridge the divide between qualitative and quantitative, as well as theoretical and applied, human research studies. These methods include multiple linear regression, nonlinear regression, stochastics, Monte Carlo methods, Markov Chains, and Lyapunov exponents. A postulate for post hoc regression analysis is then presented as an example of an emergent, recursive, and iterative quantitative method when dealing with interaction effects and collinearity among variables. This postulate also highlights the power of both qualitative and quantitative chaos and complexity theories in order to observe and describe both the micro and macro levels of systemic emergence.

Viewing dark triad as a positive personality trait, the researchers intend to explore the constructive use of impression management with regard to career success based on structural holes theory, paying particular attention to social capital and network benefits as sequential mediators between impression management and career success. A systematic literature review was conducted comprising published research studies on the chosen variables of interest. The researchers made use of several websites and links, like Google Scholar, PsychINFO, ResearchGate, and Web of Science. The systematic research was conducted to identify the desired variables and review was summarized from 2000 to 2020. Considering the past literature, it was proposed that impression management improves social capital that further leads to network benefits, thus, contributing to career success, whereas, the dark triad strengthens the relationship between impression management and social capital.  In last section, potential areas for future research in the context of impression management and dark triad are identified and a research agenda is put forward for the potential researchers. In future, researchers may benefit from the proposed conceptual model and can conduct a longitudinal quantitative research study considering the variables studied.

Over the past decade, South African organisations have had to cope with an ever-increasing rate of local and global changes. There have been considerable and ongoing socio-political changes, resulting from new government regulations. Most organisations have experienced some type of downturn, whether due to external business factors or poor internal performance. A typical response to organisational decline is retrenchment. Our study sought to explore employees’ perceptions of the effects of retrenchment on job stress and organisational commitment in a mining company. The study was located within a quantitative research paradigm. Four research hypotheses were posited and data was collected in one region from a sample of 400 surface mining employees, including management, administrators, engineers and artisans. The results showed that the effects of retrenchment did not have a negative impact on job stress (time stress and anxiety). This may be due to the fact that the mining company in question had a planning and consultation process in place for the employees prior to the retrenchment process. The results also showed that job stress (time stress and anxiety) was negatively associated with organisational commitment. To conclude this article we discuss the implications of our findings, outline the limitations of our study and make recommendations for future research.

The current research investigates the impact of internal corporate social responsibility on job satisfaction in Jordanian pharmaceutical companies. Quantitative research design and regression analysis were applied on a total of 302 valid returns that were obtained in a questionnaire based survey from 14 pharmaceutical companies among employees, supervisors and managers. The results showed that internal corporate social responsibility was significantly related to job satisfaction and three of its dimensions, namely working conditions, work life balance and empowerment contributed significantly to job satisfaction, whereas employment stability and skills development had no contribution. This study implies that Jordanian pharmaceutical companies have to try their best to promote and facilitate internal corporate social responsibility among their employees in an effort to improve their job satisfaction, which will eventually yield positive results for the company as a whole. In light of these results, the research presented many recommendations for future research; the most important ones were the application of this study in other sectors, cultures, and countries, and using of multi method for collecting data.
