The board structure (BS) is pivotal in modern corporate governance (CG). This study aims to investigate BS variables (BSIZE, BIND and chief executive officer [CEO] duality) and their correlation with risk-taking behavior indicators, enriching the understanding of how CG shapes financial institutions’ (FIs) decision-making in Pakistan.

By scrutinizing data from 67 financial entities listed on the Stock Exchange of Pakistan spanning from 2011 to 2022 through panel data regression techniques, the research emphasizes that BS holds a substantial influence over the risk tendencies exhibited by these firms.

Key findings suggest that board size has a positive influence, aligned with previous CG research. Smaller boards perform better and avoid excessive risk-taking, contrasting some negative relationship claims. More independent directors are recommended to curtail risk and financial disruption. Holding both CEO and chair roles reduces risk exposure, resonating with reputational and employment risk theory. It is essential to recognize that BS’s impact on risk-taking is nuanced and context-dependent.

Policymakers, scholars, practitioners and investors working in the market for financial companies might greatly benefit from the empirical findings of this study. Imposing mandates on FIs to uphold adequate capital reserves functions as a safeguard against unforeseen losses, thereby diminishing the probability of unwarranted risk-taking.

Prior studies in this domain predominantly focus on nonfinancial sectors. In addition, existing research often explores the relationship between BS and firm risk-taking solely within the banking sector, overlooking other FIs. This study contributes by using a comprehensive data set encompassing all types of FIs, thus extending the existing literature.

The objective of this study was to look closely at how domestic violence is represented in Pakistani drama serials to see if portrayals are reinforcing stereotypical and/or patriarchal values, or breaking the rigid norms.

With the help of dispositive analysis within the critical discourse approach, the prominent and non-dominant discourses about domestic violence were identified and discussed. Episodes from two popular drama serials, Kaisa Yeh Naseeban and Khaas, released in 2019, were watched with special focus on texts on domestic violence alongside objects and actions.

Analysis showed that both drama serials gave importance to socio-systemic and liberal humanist instrumentalism discourses, which describe domestic violence as a result of social structures and that abuse is used to assert control, respectively. However, some instances were noted where patriarchal values were encouraged.

As media has become a powerful tool of influence and awareness in the recent times, it is imperative that the content watched on it by millions of people be studied and analyzed. It is claimed that Pakistani drama serials with wide following and that are made on social issues around women aim to raise awareness and empower them. Domestic violence is a prevalent issue in Pakistan, and no research till date has examined representation of domestic violence on Pakistani popular media, which may influence response to domestic violence, which this paper aims to do.

The purpose of this paper is to analyse the determinants of Portuguese firms’ performance.

To achieve this aim, the authors used data from 37 non-financial firms in the period between 2010 and 2015. Three dependent variables were tested and the estimation of the model using the Generalised Method of Moments shows that internal, external and institutional factors are important to explain the performance of firms listed in Euronext Lisbon.

The determinants of firm performance vary depending on the variable used to measure the performance. Specifically, the results show that when the authors use a market variable of performance, the firm-specific variables are not so important to explain performance. The macroeconomic factors, including the investor’s sentiment and insider ownership, more effectively explain the firm’s performance. The evidence suggests that the determinants of firm performance change according to the way in which different stakeholders appreciate firm performance.

The main contribution of such approach is to show that internal and external factors influence performance measures in distinct ways, thus helping managers who are expected to make decisions according to the investors’ expectations. It provides initial guidelines for policy makers to understand how to improve the performance of their firms using firm-specific factors. Additionally, this work also demonstrates that the firm’s characteristics, macroeconomics and governance factors could affect the Portuguese firms’ performance, conveying a valuable contribution for investors.

The purpose of this study is to analyze the export competitiveness of Pakistan with border-sharing countries, i.e. Afghanistan, China, India and Iran for the year 2014.

The study uses revealed symmetric comparative advantage (RSCA) index to measure export competitiveness with border-sharing countries. The study has split the results into highest and marginal comparative advantage and disadvantage according to the rank.

Pakistan is exporting 160, 155, 133 and 60 commodities at three-digit level of Standard International Trade Code (Rev 3) classification to Afghanistan, China, India and Iran, respectively. The results suggest that Pakistan has highest and marginal comparative disadvantage in more than half of these commodities exported to border-sharing countries. Pakistan can improve its market share for rice in Afghanistan, China and Iran. Special measures and productive efforts are required to improve the export competitiveness of cotton, textile yarn and cotton fabric in border-sharing countries.

Pakistan has to adopt special strategies to improve the competitiveness of those commodities that fall in marginal comparative advantage and disadvantage. To increase the volume of cross-border trading, political and diplomatic channels are required among the countries especially the border-sharing countries.

Export competitiveness of Pakistan is analyzed for all the commodities exported to border-sharing countries and categorized into highest and marginal comparative advantage and disadvantage. To avoid the problem of asymmetry in Balassa index revealed comparative advantage, RSCA index is used.

Heavy metals constitute one of the most hazardous substances that could be accumulated in biota coming from human activities such as agricultural and industrial wastes. This paper aims to study the levels of some of the most common heavy metals in muscles of the fish caught in the Karun River (Ahvaz, Iran) and to assess the health risks associated with their consumption.

In present study, the concentrations of three heavy metals (Pb, Cd and Cu) in the muscle of highly consumed fish species Ctenopharyngodon Idella (Cyprinidae) collected from three selected markets (Khoram Kooshk, Ahvaz-e Qadim and Padad Shahr; total number of samples was 45) in Ahvaz city and human health risk associated with their consumption were detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

The results indicated that the highest and lowest accumulated metal concentrations were related to Cu (20.36 ± 0.84) and Cd (0.53 ± 0.02), respectively. In addition, the mean difference for Pb and Cu across two pairwise of sampling sites were significant (Ahvaz-e Qadim and Khoram Kooshk, P for Pb = 0.025, P for Cu = 0.033; Ahvaz-e Qadim and Padad Shahr, p for Pb = 0.018, p for Cu = 0.039). The estimated daily intake of all metals in muscles of fish in this study were below the legal limit, and mean differences were not statistically significant among the sampling sites, except for Cu (Ahvaz-e Qadim and Khoram Kooshk, p = 0.048; Ahvaz-e Qadim and Padad Shahr, p = 0.041). Target hazard quotient values were also all below 1.

It can be concluded that the fishes from Ahvaz city markets are comparatively clean and do not constitute a risk for human health.

The purpose of this research is to examining the effect of transformational leadership on work stress, organizational citizenship behavior (OCB) and turnover intention, examining the effect of work stress on OCB and turnover intention and examining the effect of OCB on turnover intention.

Data were collected using the survey method, with questionnaires and data analysis were done employing the WarpPLS with two approaches. This research finds the results of this study indicate that the higher the transformational leadership, the lower the work stress will be. The positive significant relationship might be because of direction or command given by the leaders to nurses at each meeting held regularly.

The results of this study indicate that the higher transformational leadership, the lower the turnover intention will be even though it is not significant. The results of this study indicate that the higher the work stress, the lower the OCB, although not significant.

Previous studies have not examined the relationship of the variables mentioned above, especially in Manado where the respondents have different cultures.

The purpose of this paper is to analyze nano zero-valent iron (nZVI)-activated carbon/Nickel (nZVI-AC/Ni) by a novel method. The synthesized adsorbent was used to degrade reactive orange 16 (RO 16) azo dye.

The optimum conditions for the highest removal of RO 16 dye were determined. Characterization of nZVI-AC/Ni was done by scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction and energy-dispersive X-ray spectroscopy. The nZVI-AC/Ni were used for the removal of dye RO 16 and the parameters affecting were discussed such as pH, adsorbent dosage, contact time and concentration of dye. To investigate the variables and interaction between them, an analysis of variance test was performed.

The characterization results show that the synthesis of nZVI-AC/Ni caused no aggregation of nanoparticles. The maximum dye removal efficiency of 99.45% occurred at pH 4, the adsorbent dosage = 0.1 gL-1 and the dye concentration of 10 mgL-1. Among various algorithms of feed-forward backpropagation neural network, Levenberg–Marquardt with mean square error (MSE) = 9.86 × 10^–22 in layer = 5 and the number of neurons = 9 was selected as the best algorithm. On the other hand, the MSE of the radial basis function model was 0.2159 indicating the good ability of the model to predict the percentage of dye removal.

There are two main innovations. One is that the novel nZVI-AC/Ni was prepared successfully. The other is that the optimized conditions were obtained for the removal of RO 16 dye from an aqueous solution. Furthermore, to the best of the knowledge, no study has ever investigated the removal of RO 16 by nZVI-AC/Ni produced.
