Structural equation modeling (SEM), with the technique of partial least squares (PLS), can be used for exploratory and predictive evaluations of the causal relationships and impact among variables postulated in theoretical models. This work presents PLS-SEM’s basic notions as a useful methodology to validate the abundance of models in the library and information science field; it offers an example of its application to test a model for measuring the impact of information resources and services on Mexican universities’ academic competitiveness; and it proposes its application to test the Information Needs Model.

This research focuses on the influence of social factors on the sustainability of hospitality industry in the context of Qatar. The significance of this research lies in its ability to empirically study the impact of social factors on the sustainability of hospitality industry in Qatar. The hypotheses building has been through the process of finding evidence through the theoretical models available in the literature for the linkages between the various social factors and sustainability. While there are several social factors which influence sustainability of any business in general, the ones which are most relevant to the hospitality industry are: Education, Life Expectancy, Income, TV index, Newspaper index, and PC index.  Structural Equation Modeling using Partial Least Square Method was used as the research methodology. This method was specifically chosen for its ability to undertake factor analysis and regression analysis simultaneously and address the issue of multi-collinearity. The sample size of 213 managers was chosen from various hotels.  The results based on the hypothesis testing would lead to the implications and also suggestions for the benefit of the hotel managers, so that sustainability of hospitality industry could be ensured.

In an effort to mitigate the impact of the COVID-19 pandemic, countries around the world have employed non-pharmaceutical containment measures. The effectiveness of such mitigation efforts relies on individual compliance (e.g., avoiding to travel or to gather). Crucially, adhering to the required behavioral recommendations places substantial burdens on those who are asked to follow them. One particularly likely outcome of adherence should be the experience of boredom. Thus, people might get bored by bothering. Drawing from research and theorizing on reward-based decision making, we conducted a high-powered study (N = 1553 US participants) to investigate whether the value and effort people ascribe to adherence to containment measures directly and indirectly (i.e., mediated by adherence) affects their experience of boredom. As expected, structural equation modeling revealed that high value and low effort predicted compliance with behavioral recommendations. Moreover, higher compliance was linked to more boredom, meaning that high value and low effort increased boredom via compliance. In contrast, high value and low effort had direct effects on boredom in the opposite direction (i.e., decreasing boredom). Attesting to their robustness and generalizability, these findings held for both prospective (with respect to upcoming winter holidays) and retrospective behavior (with respect to previous thanksgiving holidays), across US states which had or had not enforced behavioral restrictions, individual differences in boredom proneness, and demographic variables. Taken together, our results show that people can indeed get bored by bothering: Complying with nonpharmacological containment measures like avoiding to travel and to gather can come at the cost of getting bored, an experience that was strongly linked to negative affect in our study. While the observed levels of compliance were relatively high and those of boredom were relatively low, the data suggest that this could change over time because levels of boredom might rise. This might render maintenance of compliance in the general public increasingly difficult. However, we illustrate how policy makers can rely on theoretical models of boredom and behavior to maintain compliance and discuss the chances and pitfalls of doing so.

This paper uses citation analysis to measure the intellectual impact of Chinese library and information science on outside disciplines. It analyses 469 journals in disciplines outside the library and information science field containing citations to 20 Chinese library and information science journals from 1996 to 2015. It shows that Chinese library and information science mainly receives citations from related disciplines, such as business and management, communication, and computer science, and that the majority of library and information science articles are rarely cited. The library and information science subjects of bibliometrics, information technology and knowledge management are most likely to be cited.

Globally, the COVID-19 pandemic has brought significant implications to the workplace and highly impacted employee performance in every organization. In contemporary research, the scholars agree that leadership is one of the critical antecedents to predict employee performance in organizations. However, research is needed to investigate the mediating role of integral factors such as benevolence values (BV) and self-efficacy (SE) in predicting employee performance in the workplace. This study aimed to investigate the impact of key antecedents on employee performance in the banking industry. The findings reveal that the key antecedents, e.g., servant leadership (SL), self-efficacy (SE), and benevolence values (BV), have a direct positive relationship with employee performance (EP). Moreover, multiple indirect paths were tested, including serial mediation. This study used a quantitative methodology based on the positivist paradigm. A sample of 560 employees was randomly chosen. A survey questionnaire was distributed among them, and 400 were returned with a response rate of 70%, and the clean data of 400 employees was used for data analysis. The structural equation modeling (SEM) technique was employed using Smart PLS 3.3.3 software. The results confirmed that both SE and BV mediate the relationship between SL and EP. Likewise, BV mediates the relationship between SE and EP, and SE mediates the relationship between SL and BV. Finally, in serial mediation, the relationship between SL and EP is also established via SE and BV together as mediators.

The study aims to investigate the impact of participation in decision-making (PDM) and perceived organizational support (POS) on affective commitment in machinery enterprises. The study applies structural equation modeling (SEM) to test the research hypotheses. The authors surveyed 220 employees who work in machinery enterprises to collect data for the research. The study results indicate that both PDM and POS positively impact affective commitment. The findings provide empirical evidence to support the theoretical models that PDM and POS have a positive effect on affective commitment. The findings have implications for management theory: PDM and POS are the key antecedents of affective commitment. The findings also have implications for practical management in the machinery enterprises that managers should practice both PDM and POS to increase affective commitment.

Information literacy (IL) research tends to fall into one of two spaces. In the conceptual space the research concern rests with understanding the experience and core elements of the practice and how it emerges. In the practical space the execution and outcome of the practice as markers of successful teaching and learning are the focus. The division between these spaces and the lack of researcher/practitioner convergence create a conundrum that limits our ability to theorise IL, to adequately situate IL in library and information science research, to champion its benefits outside the library and information science field, or to promote to funding bodies the impact of IL. To address this conundrum a theory and foundational model of IL is described which attempts to reconstruct the IL space and its enactments without privileging research or practice.

This study aims to investigate the impact of parental career behaviors on undergraduate student’s career exploration and the mediating role of career self-efficacy. In the literature it is suggested that some social and individual factors facilitate students’ career exploration. Therefore, parental career behaviors and career self-efficacy is considered as predictors of student’s career exploration attitudes within the scope of the study. In this respect, data which are collected from 405 undergraduate students having an education on tourism and hotel management field by the survey method are analyzed by using the structural equation modeling. The results of the study indicate that parental career behaviors which are addressed support; interference and lack of engagement have a significant effect on student’s career exploration behaviors such as intended-systematic exploration, environment exploration and self-exploration. In addition, it has been found that one of the dimensions of parental career behaviors addressed as a lack of engagement has a significant effect on career self-efficacy levels of students. However, research results indicate that student’s career self-efficacy has a significant effect on only the self-exploration dimension. On the other hand, career self-efficacy has a partial mediating role between lack of engagement attitudes of parents and career exploration behaviors of students.
