Linking Ethical Leadership and Employees’ In-Role Performance: Exploring the Mediating Roles of Psychological Capital and Follower-Leader Relational Capital

This study investigates the mediating impact of psychological capital and follower-leader relational capital on the relationship between ethical leadership and in-role performance through the lenses of social exchange theory, social information processing theory, and psychological resources theory. Analysis of data collected from a sample of 171 employees and 24 supervisors from Pakistan reveals that ethical leadership has a positive effect on followers’ in-role job performance, yet this effect is fully explained through the role of psychological capital and partially through follower-leader relational capital. Significant implications of these findings for further research and practice are discussed

On effective radiational gravity acceleration at the interface of dense plasmas and vacuum

Radiative, gravitational surface waves are investigated at the interface of high density and low temperature, magnetized incompressible electron-ion plasmas in the presence of dense radiation electromagnetic radiation pressure (DEMRP). The inhomogeneous embedded is reported at plasma-vacuum interface. The DEMRP is found to stabilize the surface waves, however for a specific case, it tends to enhance the growth rate of surface waves via the frictional instability. The group velocity of gravitational radiation is shown to be the function of wavelength. The obtained analytical results are presented both numerically and graphically as function of DEMRP. to show that the incorporation of DEMRP may introduce quite different dispersive properties of charged surface wave phenomena. It is shown numerically that the frequency of the obtained radiative gravitational waves in the presence of DEMRP is found to lie in the range of high frequency radio waves, while in case of rare laboratory plasma, the frequency of these waves is found to lie within the very low frequency radio waves of the electromagnetic radiation spectrum. This work may enhance the gravitational aspects of electromagnetic radiations in dense astrophysical systems such as neutron star and white dwarfs

Effect of Oral intake of Stevia Leaf Powder on Body Weight – An Experimental study

Introduction: The steviol glycosides are found  in the stevia leaf. These glycosides possess sweetening properties as well as they have antioxidant, anti-microbial, anti-inflammatory, antihyperglycemic, and anti-hypertensive effects. This study was conducted to  find out the effect of Stevia leaf on body weight in obese Sprague Dawley male rats. Materials and Methods: This experimental study was carried out on 90 Sprague Dawley male rats. Group1(normal control) was given a standard diet for the entire study period, while the remaining sixty rats were given a high-fat diet (HFD) for 8 weeks to induce obesity. The obese rats were randomly assigned to group 2 (Obese Control) and Group 3 (obese + Stevia) and given HFD for another 6 weeks. The stevia leaf powder was added to the diet of group 3. Diet intake was noted for all the groups. Rats were weighed on the first day of every week, for six weeks, and then at the end of the study period.      Results: Body weights of rats in each group, at the start and end of the 6-week intervention period, when compared, showed a significant increase in group 1 (p=0.001), and group 2 (p = 0.001), while group 3 showed a non-significant increase (p = 0.248). The percentage increase in body weight for groups 1, 2, and 3 was 4.8, 9.3, and 1.1, respectively. Graphically, the weekly increase in average body weights of the three experimental groups showed maximum values for group 2. Conclusions: Stevia leaf possesses weight-reducing effects which may be due to inhibition of appetite, reduction in food intake, and consequent weight loss. Keywords: Obesity, weight loss, Natural non-nutritive sweeteners, Stevi

Myths and fallacies about epilepsy among residents of a Karachi slum area

Misconceptions about epilepsy may explain the considerable stigma accompanying it. We aimed to identify such fallacies through questionnaire-based interviews of 487 adult residents of a slum area in Karachi, Pakistan. Of those interviewed, 25% believed that epilepsy was caused by evil spirits, black magic and envy by others those without a school education were more likely to hold these views (P \u3c 0.05). Perceived complications included impotence and cancer. Shoe-sniffing was considered a treatment modality by 13%. It appears that misconceptions abound regarding epilepsy\u27s causes, complications and methods of treatment. However, those who had received a school education were less likely to link epilepsy with supernatural phenomena

Threshold primary tumour sizes for nodal and distant metastases in papillary and follicular thyroid cancers.

Abstract BACKGROUND: In papillary and follicular thyroid cancers (PTC, FTC), nodal and distant metastasis are generally considered important determinants of recurrence and survival, respectively. However, there is no consensus about the threshold primarytumour size (PTS) for these determinants. The aim of this study was to assess size relationships for developing nodal, pulmonary, bone and overall distant metastases. METHODS: This prospective study covered 139 (93 females and 46 males) consecutive biopsy proven patients with PTC (114/139, mean age 41.0 ± 15.7 years, M: F, 35%:65%) and FTC (25/139, mean age 39.2 ± 14.3 years, M: F: 24%:76%). RESULTS: Average primary tumor size was 23.4 ± 11.1 mm and 26.5 ± 13.1 mm for PTC and FTC respectively (p value=0.223). Nodal metastasis was found more common in PTC than FTC (49% vs 28%, p value \u3c0.05), whereas overall distant metastasis was approximately the same (13% and 24%, p value =0.277); however, bone metastasis was significantly higher in FTC than PTC (24% vs 5%, p value \u3c0.05). Cumulative risk for nodal and distant metastases for FTC and PTC starts at PTS \u3c20 mm and may indicate an unusual aggressive tumor behavior in the studied population. Highest cumulative risk for nodal and pulmonary metastases in PTC and for bone metastasis in FTC was found to be ≥ 50 mm PTS. CONCLUSION: We conclude that a PTS of \u3c20 mm may indicate an unusual aggressive tumor behavior with highest cumulative risk for nodal and pulmonary metastases in PTC and for bone metastasis in FTC with a cutoff of ≥ 50 mm

The role of space and place in organisational and institutional change : a systematic review of the literature

We present a systematic review of empirical articles investigating the role of place and space within the organisational and institutional change literature. In taking stock of the change literature, our aim is to better understand the nature and degree of scholarly engagement with concepts associated with place and space to inform a future research agenda. Our systematic review identified 290 empirical articles published between 1979 and 2020 that attended to organisational or institutional change and also engaged with space or place. Our analysis generated four archetypal perspectives that represent qualitatively different ways of viewing the role of place and space in how organisations and institutions change: functional perspective, situated perspective, experiential perspective, and mutually constituted perspective. We synthesise the four perspectives into a typology that reveals different levels of attention to change as process and to place and space as lived or physical phenomena, and cast light on different assumptions about the relationships between change and place or space that can guide future research

CPEC Investment Opportunities and Challenges in Pakistan

China-Pakistan Economic Corridor (CPEC) is related with energy and infrastructural projects. China has made massive investments in Pakistan so the region will attract reasonable foreign direct investments. Three routes are developed for infrastructural development i.e. Khunjerab to Gwader, establishment of railway, airport and seaport at Gwader so lot of prospering opportunities will be for the areas of Khyber Pakhtunkhwa and Baluchistan. As CPEC is a combination of the myriad projects on infrastructure and energy sector and these projects will be supported by an investment of $46 billion, whereby$ 35 billion will be spent on energy sector and remaining $11 billion will be spent on infrastructural developments. This review considered the available research on the prospects and issues of CPEC and provides implications for research and Pakistani economy. Available research on CPEC and its implications is descriptive in nature. There is a need to conduct sector specific studies to lay out policies and framework of action to capitalize on the opportunities provided by CPEC
