This article investigated whether wellbeing at work mediates the relationship between psychological capital (PsyCap) and performance. It also assessed the validity of the widely used measure for PsyCap—the psychological capital questionnaire (PCQ)-24, in the Indian work context. A sample of 225 employees from different private sector industries filled up the questionnaires, measuring PCQ-24, wellbeing (index of psychological well-being at work) and performance (Greene–Shortridge scale of job performance). The scales were validated using confirmatory factor analysis, and the mediation model was tested using Hayes PROCESS macro. The results showed that PCQ-24 mediates the association between PsyCap and performance. PsyCap influenced job performance by way of augmenting wellbeing at work. The PCQ-24 was also found to be a valid measure in the Indian work context with a few modifications. The results were discussed using cognitive positive appraisal of work-related factors, conservation of resources theory (COR) and broaden and build theory.

The present study emphasizes the molecular interactions between human brain acetylcholinesterase (AChE) and the natural ligand Huperzine-B and its comparison to 'AChE-Tolserine interactions'. Docking between Huperzine-B and AChE was performed using 'Autodock4.2'. Hydrophobic interactions and hydrogen bonds both play an equally important role in the correct positioning of Huperzine-B within the 'catalytic site' of AChE to permit docking. However, docking of Tolserine to AChE is largely dominated by hydrophobic interactions. Such information may aid in the design of versatile AChE-inhibitors, and is expected to aid in safe clinical use of Huperzine-B. Scope still remains in the determination of the three-dimensional structure of AChE-Huperzine-B complex by X-ray crystallography to validate the described data. Furthermore, this study confirms that Huperzine-B is a more efficient inhibitor of human brain AChE compared to tolserine with reference to Ki and ΔG values.

Temperature is considered as an important environmental factor, and the increasing water temperature resulting from global warming is a great concern. The present study was conducted to examine the effects of elevated water temperature on growth, hemato‐biochemical parameters in Nile tilapia, Oreochromis niloticus acclimatized to three temperatures (31°C, 34°C and 37°C) for 60 days. Additionally, erythrocytic cellular abnormalities (ECA) and erythrocytic nuclear abnormalities (ENA) tests were assayed using peripheral erythrocytes after exposure to the three temperatures. Fish were sacrificed on days 7, 15, 30 and 60 of exposure. Growth performances viz., weight gain, % weight gain and specific growth rate (SGR) showed decreasing tendency at 34°C but significantly declined at 37°C compared to 31°C. The abundance of haemoglobin (Hb) and red blood cells (RBCs) significantly decreased in response to temperature increases, while white blood cells (WBCs) displayed the opposite response. At days 7 and 15, blood glucose levels significantly increased in response to the temperature increase, while at days 30 and 60 glucose declined. Frequencies of ECA and ENA were significantly enhanced at the highest temperature throughout the experimental period. Dissolved oxygen decreased and free CO2 increased significantly with increasing temperature throughout the study period. The present study revealed that temperatures higher than 34°C may be hazardous to O. niloticus.

The aim of the study was to explore the career aspirations of the youth in Manipur, and data were collected through focus group discussions from 18 participants. The analysis of the data using thematic analysis was done to identify themes to develop an understanding of what careers these youth aspire for and the barriers to their aspirations. Four major themes identified were aspirations, barriers, support from family, and impact of the insurgency. The participants were found to have high career aspirations, clarity with regard to what they want to achieve in life, and desire to have careers that let them work for the betterment of their community. Limited job opportunities in Manipur and underdevelopment of private sector were attributed as major barriers. Participants from lower socioeconomic status reported facing greater challenge. Emotional as well as monetary support from family facilitated high career aspirations and perseverance in achieving them.

Terms of trade is an important indicator of the welfare gains from international trade to the exporting country. Terms of trade of oil-exporting countries are hypothesized to depend primarily on oil prices. The study assesses the relation between oil prices and the terms of trade of Saudi Arabia. The study uses the Autoregressive Distributed Lag method to determine the cointegration between the country's terms of trade and oil prices for the period 2000-2018. The data for net barter terms of trade is taken from World Development Indicators and oil price is taken from Saudi Arabian Monetary Agency. The results show that oil prices and terms of trade are cointegrated and any disequilibrium between the two variables is corrected by 35% in a year. The study also reports a positive relationship between the two items, both in the short run and long run. Diagnostic tests indicate the model to be fit. The results suggest that, for a primarily oil-producing country like Saudi Arabia, the terms of trade depend on oil prices. The study fills the gap in the literature on the study of terms of trade for Saudi Arabia for the last few years, where there has been a high volatility in oil prices.

DOI: dx.doi.org/10.17017/jfish.v2i2.2014.27 Abstract This study was carried out at the Disease Laboratory of the Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh, Bangladesh to verify the therapeutic performances of six commercial aqua drugs; three doses were selected as less than recommended, recommended and more than recommended to assess their performances. Before starting therapeutic experimental nine climbing perch (Anabas testudineus) and six stinging catfish (Heteropneustes fossilis) were confirmed as diseased ones by their clinical signs. The backswimmers (Notonecta glauca) were collected from faculty of fisheries pond and fish louses (Argulus sp.) were collected from tilapia fishes. Effective doses and their performances were determined on the basis of desired water quality change and clinical signs. It was found that all the drugs performed better at more than recommended doses as follows Aqua Ox performed better at the rate of 0.2 mg/l, GR Plus, 0.0005 ml/l, ID Plus (5%), 0.00026 ml/l; Active Blue, 0.0002 ml/l; Hashpoka Killer, 0.0001 ml/l; and Para Control, 0.001 ml/l. So these doses were suggested as recommended doses.
