Abstract

Purpose

The field of library and information sciences (LIS) is crucial to our educational system. Across the globe, the LIS systems operate at varying levels and rates of efficiency. One of the developing nations is Pakistan, which has LIS systems in all of its colleges, universities and schools. This multimethod study aims to identify and quantify elements that are detrimental to LIS progress as well as evaluate the faculty and infrastructure profiles of universities that offer LIS undergraduate and graduate level programmes.

Design/methodology/approach

Data was collected from the study's participants, who were mainly LIS professionals and faculty at 17 different universities, using survey questionnaires and in-person interviews. This study used a descriptive survey methodology, gathering information through a Google Survey and filling it out with a premade survey proforma. The survey responses were examined using content analysis. The development of LIS instructional and scholarly output is influenced by a variety of factors, which were investigated using a generalized linear model (GLM). To determine whether there was a statistically significant difference in opinion between faculty members and working professionals, as well as between men and women, the outcomes of an independent sample t-test were examined.

Findings

According to our data, the factors that have the biggest impact on the caliber and output of LIS research are “poor writing skills” (3.43), “lack of journal publication fees” (3.51) and “lack of research skills” (3.78). The top GLM model identified poor writing skills, a lack of publication fees and a lack of research expertise as bottleneck characteristics for producing high-quality LIS research. The aforementioned factors were 3.62, 2.41 and 2.19 times more significant than the average factor, respectively, to put it another way.

Originality/value

This study’s analysis revealed that there is no real distinction between the two groups' viewpoints. The results of this study can be applied to problems and challenges associated with LIS education in Pakistani educational institutions.

Abstract

Purpose

This study aims to investigate the status of library and information science (LIS) education in Pakistan, as well as LIS progress, level of employment and issues, infrastructure and facilities, challenges faced by LIS institutions and future prospects of the profession.

Design/methodology/approach

A total of 115 permanent/regular and visiting academic members from different Pakistani institutions/universities participated in the research. A mixed-method was used, and data was collected through questionnaires and interviews. The data was analyzed quantitatively and qualitatively.

Findings

This study’s results showed that assistant, associate and associate professors have been very involved in producing high-quality research articles and producing quality graduates. This study also found that there are several problems with LIS education in Pakistan, such as a lack of qualified teachers, resources and facilities. This study provides all the answers to these problems. They are useful for LIS teachers and students in Pakistan because LIS education has been around for a long time, but there are still some problems that need to be fixed. The results could have an immediate effect on the direction, ability to survive and future of LIS education in Pakistan.

Originality/value

Previously, different studies have been conducted on evolution and challenges to the LIS profession, but to the best of the authors’ knowledge, no study has been reported based on the professional experiences in other Universities of Pakistan. According to the research, the findings are crucial for LIS professors and students in Pakistan. In addition, the research investigates the challenges faced by LIS teachers in Pakistan. It concludes with suggestions on how to address some of these problems. It is also said that Pakistan must develop universal standards for LIS to close the gap between what users want and what library workers can do.

Abstract

Purpose

The purpose of this study is to answer whether and how supervisor–subordinate instrumental or expressive ties based on enterprise social media (ESM) might enhance employee performance.

Design/methodology/approach

Drawing on social exchange theory, this study developed a theoretical model to explore the influencing mechanism of different supervisor–subordinate ties based on ESM on employee job performance. The model was empirically tested through 219 ESM users.

Findings

The results revealed that supervisor–subordinate instrumental ties based on ESM play a positive role in employee job performance, while supervisor–subordinate expressive ties based on ESM are not significantly related to employee job performance. Supervisor–subordinate instrumental ties and expressive ties based on ESM can positively influence employee job performance through the mediating effect of organizational trust. Besides, perceived performance climate can weaken the relation of organizational trust to job performance, and then weaken the indirect relations via the mediating of organizational trust.

Originality/value

Our findings advance the understanding of ESM use through various underlying mechanisms and have the potential of guiding organizations to fine-tune their social media usage strategies.

Abstract

Purpose

Sustainability is of growing significance in the contemporary business landscape as organizations strive to minimize their environmental impact and optimize supply chain (SC) operations. Gaining insights into the influence of Triple A SC practices on sustainable performance can offer valuable perspectives for practitioners and policymakers. This study aims to comprehensively review existing academic literature on Triple A supply chain management (SCM) and sustainability, examining its impact on sustainable performance while identifying key influencing factors.

Design/methodology/approach

This review follows the six steps and 14 decisions of conducting a systematic literature review to comprehensively review 57 papers published between 2004 and 2023.

Findings

Based on the content analysis of the selected papers, this study summarizes the antecedents, practices and outcomes of Triple A SCM, with a particular focus on its implications for sustainability. This paper builds a conceptual framework from the descriptive and thematic findings to enrich the relevant aspects of Triple A SCM.

Originality/value

This study establishes a connection between Triple A SCM and sustainable performance by examining its impact on economic, social and environmental aspects. This review identifies research gaps and acknowledges the lack of specificity in implementing Triple A SCM across diverse industries, regions and competitive markets with varying external environments. It emphasizes the necessity to customize approaches based on contextual factors and provides valuable recommendations for future research to advance the concept of Triple A SCM.

This study analyzes the causal effect of education on consumers' cognition and attitudes toward genetically modified (GM) foods.

Abstract

Purpose

This study analyzes the causal effect of education on consumers' cognition and attitudes toward genetically modified (GM) foods.

Design/methodology/approach

The authors propose an analytical framework to clarify the role of education levels and education content in the formation of attitudes toward GM foods and utilize education reforms in China as natural experiments to test the theoretical predictions empirically. For education levels, the authors use Compulsory Education Law's implementation to construct the instrument variable. For education content, the authors utilize the revision of the biology textbook in the Eighth Curriculum Reform to implement staggered difference-in-difference estimation. The authors use two national household surveys, the China Genuine Progress indicator Survey (CGPiS) and the China Household Finance Survey (CHFS) of 2017, combined with provincial-level data of education reforms.

Findings

The education level, instrumented by the Compulsory Education Law's implementation, has an insignificant effect on consumers' cognition and attitudes toward GM foods, whereas the acquisition of formal education on genetic science, introduced by the Eighth Curriculum Reform, has a statistically significant and positive influence.

Originality/value

This is the first study to investigate the causal effects of education level and content on consumers' cognition and attitude toward GM foods using national representative data. It is also the first to evaluate the long-term effects of the biology textbook reform in China. The findings help open the black box of how education shapes people's preferences and attitudes and highlight the significance of formal biology education in formulating consumers' willingness to accept GM foods.

Abstract

Purpose

The purpose of this study is to explore the relationship between information overload and employees' workplace anxiety in the context of enterprise social media (ESM).

Design/methodology/approach

This study built a theoretical model to analyze the relationships among employees' perceptions of information overload on ESM, supervisor-subordinate instrumental and expressive ties on ESM and workplace anxiety. PLS-SEM was used to test the model through 219 questionnaires collected online.

Findings

The results revealed that information overload on ESM plays a positive role in employees' workplace anxiety. Supervisor-subordinate instrumental ties based on ESM can weaken the relationship between information overload and employees' workplace anxiety, but expressive ties can strengthen the positive relationship between information overload and workplace anxiety.

Originality/value

Little is known about whether information overload on ESM will affect employees' workplace anxiety and how leaders can mitigate this effect through ESM. Hence, this study developed a theoretical model and conducted an empirical study to open up a research opportunity to examine the relationships among information overload on ESM, supervisor-subordinate instrumental and expressive ties on ESM and employees' workplace anxiety. The study also has the potential to guide organizations in fine-tuning their social media usage strategies.

Abstract

Purpose

Tour guides often use humor to entertain tourists, but the process of tour guide humor (TGH) affecting tourists’ positive word of mouth (PWOM) remains unclear. To fill the gap, this study aims to investigate how TGH enhances tourists’ PWOM through perceived relationship investment, perceived wellness value and trust in tour guides.

Design/methodology/approach

A comprehensive mediation model was proposed based on social exchange theory (SET). Data were obtained from 335 tour group tourists and analyzed using structural equation modeling.

Findings

Results present that TGH positively predicts tourists’ PWOM. Perceived relationship investment, perceived wellness value and trust in tour guides not only play mediating roles between TGH and tourists’ PWOM, respectively, but also jointly provide two sequential mediation paths (TGH → perceived relationship investment → trust in tour guides → tourists’ PWOM and TGH → perceived wellness value → trust in tour guides → tourists’ PWOM).

Research limitations/implications

The findings have practical value for tour guides and travel agencies to use TGH to improve tourists’ PWOM.

Originality/value

The major contribution is that a reciprocity-based framework rooted in SET was proposed to parse the complex process of TGH promoting tourists’ PWOM. Furthermore, this study enriches current knowledge by confirming that perceived wellness value is not only available in wellness tourism but can be experienced from TGH in mass tourism.

Abstract

Purpose

This paper aims to improve the accuracy of robot payload identification and decrease the complexity in its industrial application by developing a new method based on the actuator current.

Design/methodology/approach

Instead of previous general robot dynamic modeling of the actuators, links, together with payload inertial parameters, the paper discovers that the difference of the actuator torque between the robot moving along the same trajectory with and without carrying payload can be described as a function of the payload inertial parameters directly. Then a direct dynamic identification model of payload is built, a set of specialized novel exciting trajectories are designed for accurate identification and the least square method is applied for the estimation of the load parameters.

Findings

The experiments confirm the effectiveness of the proposed method in robot payload identification. The identification accuracy is greatly improved compared with that of existing methods based on the actuator current and is close to the accuracy of the methods that direct use the wrist-mounted force-torque sensor.

Practical implications

As the provided experiments indicate, the proposed method expands the application range and greatly improves the accuracy, hence making payload identification fully operational in the industrial application.

Originality/value

The novelty of such an identification method is that it does not require the rotor inertias and inertial parameters of links as a prior knowledge, and the specially designed trajectories provide completed decoupling of the load parameters.

Abstract

Purpose

Wave breaking significantly affects the exchange process between ocean and atmosphere. This paper aims to simulate the upper ocean dynamics under the influence of wave breaking, which may help to figure out the transport of energy by these breakers.

Design/methodology/approach

The authors use a breaker-LES model to simulate the oceanic boundary layer in hurricane conditions, in which breakers become the main source of momentum and energy instead of traditional wind stress.

Findings

The mean horizontal velocities and energy increase rapidly with wind speed, reflecting that input from atmosphere dominates the coherent structure in the upper ocean. The penetration ability of a breaker limits its effective depth and thus the total turbulent kinetic energy (TKE) decreases sharply near the surface. Langmuir circulation is the main source of TKE in deeper water. The authors compared the dissipation rate (e) in the simulations with two estimates and found that the model tends to the scaling of ε∼z–3.4 at extreme wind speeds.

Originality/value

The probability distribution of breakers is also discussed based on the balance between the input from atmosphere and output by wave breaking. The authors considered the contribution of micro-scale breakers and revaluated the probability density function. The results show stability in hurricane conditions.

Abstract

Purpose

To paint large workpieces automatically, painting manipulators with hollow wrists must be transported by mobile platforms to different positions because of their limited workspaces. This paper aims to provide a visualization method for finding appropriate base positions (BPs) and maximum painting areas for manipulators.

Design/methodology/approach

This paper begins by analyzing the motion characteristics of manipulators possessing a spherical wrist and summarizing them into three constraints – positioning, orientation and singularity avoidance. The hollow wrist is simplified and considered as spherical by introducing the concepts of an inner wrist center and an outer wrist center. Taking the three constraints into consideration, the boundaries of the manipulating space are formulated analytically. Finally, to verify the method, the space obtained is applied to determine the maximum painting areas for flat, cylindrical and conical surfaces. Experiments of robotic painting were used to confirm the results.

Findings

Compared with previous studies, the maximum areas obtained using the proposed method increased by 17-131 per cent with an algorithm of lower complexity, and the process remained visually intuitive, thereby demonstrating that the method of manipulating space is more effective.

Originality/value

Such a method allows individuals to visualize the entire painting area at the current BP, thereby maximizing painting areas or optimizing BPs. It opens a black box that is the relationship between BPs and blocks. The method can also be used to choose the best configuration for painting manipulators, select the end-effector structure parameters, split surfaces into blocks, etc.
