This research aims to investigate the direct and indirect (via creative self-efficacy [CSE] and thriving) effects of regulatory focus (RF) on employee intrapreneurship (EI) in Pakistan’s small- and medium-sized enterprises (SMEs).

A time-lagged (six weeks apart) design is used to collect data through self-administered questionnaires. The researchers retrieved 492 usable responses from frontline employees working in SMEs.

The results showed the positive direct and indirect (via CSE and thriving) effects of promotion focus on EI. As expected, the results showed negative direct and indirect effects of prevention focus on intrapreneurship. The follow-up analysis revealed the mediating effect of CSE is stronger for the promotion focus and intrapreneurship, and the mediating effect of thriving is stronger for prevention focus and intrapreneurship.

This study reveals the importance of RF facets as important predictors of EI. The study highlights the importance of intrapreneurship in emerging economies, but expecting such behavior from every employee is a fallacy. Thus, decision-makers in organizations can nurture prevention-focused employees to engage in intrapreneurship.

This is a pioneer study to include RF (promotion focus and prevention focus) in an emerging country – Pakistan – to reveal its significance in EI. It establishes CSE and thriving as mediating mechanisms between RF and EI for the first time to offer new insights into theory and practice.

This research aims to investigate relationship between workplace spirituality and employees' knowledge-hiding as mediated by organizational identification.

In this research, a time-lagged design is employed and multi-source data are collected through self-administered questionnaires. A sample of 305 focal respondents and 1,048 of the respondents' peers is used to test the hypotheses using AMOS (analysis of moment structures) 24.0.

The results reveal that two dimensions of workplace spirituality – meaningful work and values alignment –play significant roles in reducing knowledge-hiding in terms of workplace spirituality's three dimensions of evasive hiding, rationalized hiding and “playing dumb.” However, contrary to expectations, a sense of community has significant positive effects on the dimensions of knowledge-hiding. The study also reveals that organizational identification significantly mediates the relationships between the dimensions of workplace spirituality and those of knowledge-hiding.

This pioneer study introduces workplace spirituality (which differs from religious spirituality) and the significance of workplace spirituality in the workplace in the religious and conservative society of Pakistan. This study uses the lens of social identity theory (SIT) to establish for the first-time organizational identity as a mediating mechanism between workplace spirituality and knowledge-hiding to offer new insights for theory and practice.

Because of its increased absorptance in fluid and reduced heat loss, direct absorption nanofluid (DANF) is receiving intense interest as an efficient way to harvest solar energy. This work aims to investigate, for the first time, the application of DANF in parabolic trough collectors (PTC), a promising collector for solar thermal systems.

A representative flow and heat transfer study of different fluids in a straight tube is conducted, and the basic energy equation and radiative transfer equations are numerically solved to obtain the fluid temperature distribution and energy conversion efficiency. Ethylene glycol (EG) and different concentrations of (i.e., 0.1-0.6 per cent) multi-wall carbon nanotubes (MWCNT) in EG are used as sample fluids. Four cases are studied for a traditional PTC (i.e., using metal tube) and a direct absorption PTC (i.e., using transparent tube) including a bare tube, a tube with an air-filled glass envelope and a tube with vacuumed glass envelop. The numerical results are verified by an experimental study using a copper-glass absorber tube, which reveals the good potential of DANFs.

Compared with a conventional PTC, using DANF shows an increase of 8.6 per cent and 6.5 K, respectively, in thermal efficiency and outlet temperature difference at a volume fraction (0.5 per cent) of nanoparticles. The results also show that the improvement in solar efficiency increases with increasing particle concentrations, and the vacuum insulated case has the highest efficiency.

In all previous studies, an important section was missing as the effect of photons on the direct solar absorption trough collector, which is considered in this study. This paper proposes a new concept of using direct solar absorption nanofluids for concentrated solar collectors and analyzes the performance of both absorptance and transmittance efficiency considerations. To reveal the potential of the new concept, an analytical model based on energy balance is developed, and two case studies are performed.

Reviews previous research on the factors affecting the proportions of debt and equity used to finance firms, describes the Saudi Arabian tax system (based on net worth) and stock market; and examines the capital structure 1993‐1997 of a sample of 35 publicly traded Saudi companies. Uses multi‐linear regression models to investigate the relationships between capital structure and other variables in 5 sectors and illustrates their varied leverage ratios. Discusses and analyses the positive links between leverage ratios, firm size and share of government ownership; and negative links with growth, return on assets and profitability margin.

Explains how the adoption of Islamic law (Shariah) theoretically affects a political economy, why it requires the abolition of interest rates as a price for money and how this is achieved. Takes Saudi Arabia as an example of a Muslim country governed by Shariah and investigates how far it accords with theory. Argues that equity financing (including non‐interest bearing government bonds) has helped to finance growth and insulated the stock market from speculative financing. Looks at statistics on the financial structures, assets and loans of Saudi banks (including joing ventures with foreign banks) and concludes that they have “done well” in implementing Islamic principles; and that interest‐free financing is appropriate for this country.

This chapter builds upon the analysis of the last chapter, as fans have to deal with the issues that arise from their team’s financial superiority. Here, we question what happens when that financial superiority is accompanied by significant moral and ethical issues. Recent involvement of state actors in the ownership of English football has been evidencable and occasionally appears clear. Various reflexes and cognitive distancing occur from fandoms when football club ownership engages in practices that, according to the normative models that fans ascribe to their clubs, are mutually exclusive with the values of the fanbase and the club’s history. A common form of fan reflex often takes the form of distancing the players on the pitch from the club’s institutional structures, effectively teasing out the matchday experience from the structures that benefit from the raw emotion it generates. Another reflex is questioning why the fan should surrender their club when a morally, ethically problematic ownership model has acquired it. Here we have perhaps the greatest challenge to the normative model and, rather than negotiating that tension, as often as not the response is to try and ignore it.

Drawing on the positive activity model, this study aims to investigate the impact of workplace spirituality on the level of engagement shown by the teachers at higher education institutions. This study also tries to explore if emotional intelligence acts as a mediator in the relationship between workplace spirituality and employee engagement.

Using the purposive sampling technique, data were collected from the teachers (N = 287) teaching at various Indian educational institutions imparting tertiary education. The variables under study were measured using standardized instruments. The data were analyzed by means of Statistical Package for Social Sciences 20.0 and Analysis of Moment Structures software tools.

The findings generated from structural equation modeling analysis revealed that the teachers who practiced spirituality at their workplace were more engaged. Furthermore, emotional intelligence partially mediated this relationship.

This study underscores the importance of providing a spiritually conducive work milieu and nurturing emotional intelligence among the higher education teachers for better job outcomes.

This study offers insights into the mechanism linking spirituality at the workplace (a positive activity) and employee engagement (an indicator of well-being) in the context of higher education sector.

The paper aims to present a grid-connected multi-inverter for solar photovoltaic (PV) systems to enhance reliability indices after selected the placement and level of PV solar.

In this study, the associated probability is calculated based on the solar power generation capacity levels and outages conditions. Then, based on this probability, dependability indices like average energy not supplied (AENS), expected energy not supplied and loss of load expectations (LOLE) are computed, also, another indices have been computed such as (customer average interruption duration index (CAIDI), system average interruption frequency index (SAIFI) and system average interruption duration index (SAIDI)) addressing by affected customers with distribution networks reliability assessment, including PV. On the basis of their dependability indices and active power flow, several PV solar modules installed in several places are analyzed. A mechanism for assessing the performance of the grid's integration of renewable energy sources is also under investigation.

The findings of this study based on data extracted form a PV power plant connected to the power network system in Diyala, Iraq 132 kV, attempts to identify the system's weakest points in order to improve the system's overall dependability. In addition, enhanced reliability indices are given for measuring solar PV systems performance connected to the grid and reviewed for the benefit of the customers.

The main contributions of this study are two methods for determining the reliability of PV generators taking into consideration the system component failure rates and the power electronic component defect rates in a PV system which depend on the power input and the power loss using electrical transient analysis program (ETAP) program.

The purpose of this study is to explore the phase change (PC) dynamics in a T-shaped ventilated cavity having multiple inlet and outlet ports during nanofluid convection with phase change material (PCM) packed bed-installed system.

Finite element method was used to analyze the PC dynamics and phase completion time for encapsulated PCM within a vented cavity during the convection of nanoparticle loaded fluid. The study is performed for different Reynolds number of flow streams (Re₁ and Re₂ between 300 and 900), temperature difference (ΔT₁ and ΔT₂ between −5 and 10), aspect ratio of the cavity (between 0.5 and 1.5) and nanoparticle loading (between 0.02% and 0.1%).

It is observed that phase transition can be controlled by assigning different velocities and temperatures at the inlet ports of the T-shaped cavity. The PC becomes fast especially when the Re number and temperature of fluid in the port vary closer to the wall (second port). When the configurations with the lowest and highest Re number of the second port are considered up to 54.7% in reduction of complete phase transition time is obtained, while this amount is 78% when considering the lowest and highest inlet temperatures. The geometric factor which is the aspect ratio has also affected the flow field and PC dynamics. Up to 78% reduction in the phase transition time is obtained at the highest aspect ratio. Further improvements in the performance are achieved by using nanoparticles in the base fluid. The amounts in the phase transition time reduction are 8% and 10.5% at aspect ratio of 0.5 and 1.5 at the highest nanoparticle concentration.

The thermofluid system and offered control mechanism for PC dynamics control can be considered for the design, optimization, further modeling and performance improvements of applications with PCM installed systems.
