Potato-based snacks (PBS) are widely popular among people of all age groups despite known negative health aspects. University students, due to their busy routines and less familiarity with diets are more prone to selecting unhealthy meals and snacks. The study aims to explore the outlook of university students regarding their consumption of processed and packaged PBS in their daily lives and compares gender’s PBS choices with dietary habits and food environment.

A total of 122 students from various universities across Pakistan were included in this study. The data were collected using a structured questionnaire and distributed using the snowball method.

The university students showed a significant difference in their living habits (p = 0.016), where 25.4% of enrolled male students were hostellers as compared to females (14.8%). Significant differences were noticed in choosing PBS that further depends on the familiarity of the product, (p = 0.030), where 9.0% of female students rated familiarity with the product as being important while 20.5% of males responded familiarity as a critical factor. Studying the usual location/point of purchase for a PBS, a significant difference was observed (p = 0.008%) where more male students (27.9%) choose to buy their PBS from a local convenience store as compared to female students (18.9%). Female students (13.1%) would rather choose to buy their PBS on their weekly grocery runs.

This study concluded that female and male students’ attitudes regarding the consumption of PBS were almost the same regardless of environment and brand repute.

The purpose of this paper is to access the present situation of the Pakistani population that suffers from vitamin D deficiency.

A review-based study was conducted based on publications from Pakistan between the years 2008 and 2018. The publications were archived from Pub Med and Google Scholar databases. A total of 18 publications were shortlisted, based on the cutoff values of vitamin D sufficiency, insufficiency and deficiency.

As per the data, 38.5 per cent of the participants were males, 48.7 per cent were females and 12.8 per cent of the studies have not mentioned the genders of the participants. The cumulative results show that 58.17 per cent (95 per cent CI: 52.17, 64.16) of the population is vitamin D-deficient and 26.65 per cent (95 per cent CI: 21.63, 31.66) is insufficient in vitamin D. The highest level of vitamin D deficiency was reported from Sindh (62.15 per cent), followed by Khyber Pakhtunkhwa (60.57 per cent), Punjab (51.75 per cent) and the Federal Capital (49.25 per cent). Moreover, Cochran’s Q test indicated considerable heterogeneity (p = >0.001) with regard to Vitamin D deficiency (VDD) prevalence found among samples from the selected studies.

The present analysis suggests that more than half of the Pakistani population suffers from VDD, which, thus, should be considered as an epidemic and treated likewise.

The novel coronavirus (SARS-CoV-2) variant of 2019 has taken more than 3.8 million lives according to the World Health Organization. To stop the spread of such a deadly and contagious disease, lockdown of varying nature was imposed worldwide. Lockdown, preventive techniques and observation of standard operating procedures (SOPs) have effectively decreased the spread of contagious diseases but have affected various businesses and industries economically. The food industry has been hit hard by different restriction parameters, due to which a disruption in food supply and demand was observed. Therefore, this study aims to study this disruption in the supply chain of processed food.

A comprehensive review was conducted on PubMed, Google Scholar, and Scopus to locate articles on processed foods, food delivery and supply chain. The selected articles were evaluated using the context analysis method.

The pandemic situation has increased the consumption and demand for processed food products from retail stores, and decreased the demand for food service products. These circumstances called for technological advancement in the field of food supply from farm to fork. This study reviews research articles, policies and secondary literature. Several advances have been made to deliver safe, nutritious and wholesome food to consumers. Block chain-based food supply chains, value stream mapping, sustainable supply chain domain and online ordering systems via mobile apps have been discussed in correspondence with information and communication technology (ICT) during COVID-19.

This study concludes that the use of advanced software and its adequate knowledge by suppliers, logistics companies and consumers have assisted in handling shocks to the global food system and provided in-time food delivery, traceability, database information and securely processed food to consumers.

This study shows the effects of COVID-19 pandemic on global food systems; disruption in food demand and supply chain is overlooked and changed; use of technological advances in food supply chain to tackle pandemic; online food ordering system gained popularity and improved technically.

The present study was carried out to determine (1) essential minerals, total polyphenols, total flavonoids, moisture and ash of four selected South African herbal teas and (2) the effect of blending bush tea with other known commercial herbal teas.

The method used to determine moisture and ash contents followed that of the Association of Official Analytical Chemists (AOAC). Nine minerals were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES). The total phenolic and flavonoid contents were determined by Folin–Ciocalteu assay and aluminum chloride colorimetric assay, respectively.

The results of the study demonstrated that bush tea had a high ash content of 8.01% and special tea (9.23%), while honeybush (1.96%) and rooibos tea (2.17%) exhibited a low ash percentage. The mineral content was higher in bush tea and special tea than in rooibos tea and honeybush tea except for sodium, which was higher in rooibos tea. The blending of bush tea with special tea improved its potassium content from 22,937.00 mg/kg to 23,379.20 mg/kg. Blending bush tea with rooibos tea at a ratio of 25:75 increased the flavonoid content to 12.21 µg/mL.

The results of the nutrients composition cannot be generalized as it is influenced by other factors such as soil type and seasons.

Increasing the commercialization of indigenous teas.

The results of the study suggest that bush tea and special tea are nutritionally comparable with South African commercial herbal teas. Thus, the consideration for commercialization of these teas is crucial.

This study aims to unpack the link between co-worker incivility and job performance, by detailing a mediating role of psychological detachment and a moderating role of psychological capital.

The research hypotheses are tested with three-wave, time-lagged data collected from Pakistani-based employees and their supervisors.

An important reason that disrespectful co-worker treatment curtails job performance, with respect to both in-role and extra-role work efforts, is that employees detach from their work environment. This mediating role of psychological detachment is less salient to the extent that employees possess high levels of psychological capital.

For organizations, this study pinpoints a key mechanism, a propensity to distance oneself from work, by which convictions that co-workers do not show respect direct employees away from productive work activities. This study also shows how this mechanism can be subdued by ensuring that employees exhibit energy-enhancing personal resources.

This study expands extant research on the dark side of interpersonal co-worker relationships by revealing pertinent factors that explain why and when co-worker incivility can escalate into diminished performance-enhancing activities.

This study aims to examine the impact of COVID-19-related job insecurity on two types of employees’ behaviors: family undermining and withdrawal. This study also proposes emotional exhaustion as a mediator and symmetrical internal communication as a moderator in the relationship between COVID-19-related job insecurity and employees’ behaviors.

Using a time-lagged design, data were gathered from 193 employees working in Pakistan’s hospitality sector. Structural equation modeling in AMOS and PROCESS Macro were used to test the hypotheses.

The results show that COVID-19-related job insecurity is positively related to family undermining and withdrawal behaviors, and these associations are mediated by emotional exhaustion. Furthermore, symmetrical internal communication weakens the positive influence of COVID-19-related job insecurity on emotional exhaustion. Additionally, the indirect impact of COVID-19-related job insecurity on employees’ behavioral outcomes via emotional exhaustion is stronger for employees with low symmetrical internal communication than for those with high levels of symmetrical internal communication.

Hospitality management needs to focus on transparent and horizontal communication patterns to reduce the ensuing negative behaviors from COVID-19-related job insecurity.

To the best of the authors’ knowledge, this is the first study to examine the impact of COVID-19-related job insecurity on two types of employees’ behaviors: family undermining and withdrawal. This study also offers new insights via mediating mechanisms and moderators associated with the relationship between COVID-19-related job insecurity and employees’ behavioral reactions.

By applying displaced aggression and conservation of resource theory, this paper aims to investigate the effect of supervisors’ workplace stress over subordinates' unethical behavior through displaced aggression as an underlying mechanism. Moreover, it tests the moderating effect of despotic leadership between supervisors’ workplace stress and displaced aggression.

The data consists of three hierarchy levels: despotic leadership (top manager), supervisor’s (immediate supervisor/middle manager) workplace stress and displaced aggression and subordinates’ unethical behavior. The data was collected from 80 managers about their workplace stress and displaced aggression besides perceived unethical behavior of their 240 subordinates.

The data analysis of 80 bank managers of Pakistan about their perception of top managers’ despotic behavior and unethical behavior of their 240 subordinates shows the support for all hypothesized relationships. Supervisors’ workplace stress positively affected their displaced aggression over their subordinates, which motivated subordinates to engage in unethical behavior. Moreover, the findings supported the moderating effect of despotic leadership in the relationship between supervisors’ workplace stress and displaced aggression.

This study contributes to the limited studies on the trickledown displaced aggression phenomenon in the service (banking) sector. Moreover, the manager’s despotic leadership role as a higher-level negative supervisory behavior in increasing the supervisors’ displaced aggression shows the critical aspect in such a stressful workplace situation.

With an emphasis on displaced aggression theory and social exchange theory, this study aims to investigate the harmful effects of exploitative leadership (EL) on employee creativity (EC) through the mediating role of knowledge hiding (KH). Moreover, this study examines the boundary effects of leader–member exchange (LMX) to explore conditions under which KH is more or less likely to occur.

The study employed time-lagged (i.e. three-wave), multisource (i.e. self-rated and peer-rated) research design to collect data from employees working in Pakistani service sector organizations. The study analyzed 323 responses using SMART PLS (v 3.3.3) to assess the measurement model and the structural model.

The findings reveal that EL is positively related to KH and negatively related to EC. The results also show partial mediating role of KH in the indirect relationship between EL and EC. Besides, the study also found that LMX moderates the positive relationship between EL and KH, and the negative relationship between EL and EC.

The study divulges interesting findings that subordinates at high-quality LMX relationships (i.e. in-group members) are more susceptible to the harmful effects of supervisory unjust treatment than at low-quality LMX relationships (i.e. out-group members). Thus, occurrence context of KH, i.e. EL should be minimized through appropriate organizational interventions.

This study contributes to the leadership and knowledge management literature by testing a hitherto unexplored moderated mediation model.

This study aims to investigate the outcomes of customers’ co-creation experience in a realistic and routinely performed co-creation setting, a restaurant. To fulfill this purpose, the current study links the branding literature to hospitality research and offers a novel framework by incorporating customers’ co-creation experience, customer brand engagement, emotional brand attachment and customer satisfaction in an integrated research model.

Data were collected from 421 diners at Chinese hotpot restaurants via a self-administered questionnaire. The reliability and convergent and discriminant validities were established through confirmatory factor analysis, and then hypotheses were tested through structural equation modeling.

This study demonstrates that customers’ co-creation experience with a restaurant brand positively impacts customer brand engagement, emotional brand attachment and customer satisfaction. In addition, current study examines these relational paths at the dimensional level by taking the co-creation experience and customer brand engagement as multidimensional constructs. The resulting in-depth investigation reveals that the hedonic, social and economic experience dimensions of co-creation experience positively influence customer satisfaction, emotional brand attachment and customer brand engagement’s buying, referring, influencing and feedback dimensions.

This study helps relationship and brand managers better understand customer experience in co-creation settings and paves the way for managers to devise engagement strategies.

The current study marks an initial attempt to delineate the outcomes of customers’ co-creation experience in a realistic co-creation setting. Furthermore, the study is first of its kind that investigates the relationship of co-creation experience and customer brand engagement at the dimensional level.

A paradigm shift toward a corporate model of higher educational settings has led to complex and excess work demands, yet the potential long-run ramifications of work overload are still under-examined. Building the arguments on the “spiral of resource loss” corollary of the conservation of resources (COR) theory, the authors have bridged this gap by testing how work overload spills over into career resilience via reduced harmonious passion. In addition, the authors compare how the employees having standardized workloads differ in their harmonious passion and career resilience from those having excessive (non-standardized) workloads.

Through a longitudinal natural field experiment of 402 faculty members [N = 198 in the standardized group (optimal load) and N = 204 in the non-standardized group (overload)] working in higher educational institutions of Pakistan, data were collected in three waves (each six months apart). The group comparison, trend analysis and longitudinal mediation analysis done through SPSS and MPlus affirmed the hypothesized associations.

The results have shown that work overload impacts career resilience through the mediating role of harmonious passion. The faculty members in the standardized workload had more passion and career resilience as compared to the non-standardized workload group. In addition, these impacts intensified overtime for the overloaded faculty members while faculty members with optimal workload sustained their passion and resilience for the teaching profession.

Taking the COR perspective, this study sheds light on how faculty members' work overloads reduce their capability to retain their passion and resilience for teaching from a longitudinal and experimental perspective.
