Factors affecting employees’ performance: the case of telecommunication company, Jordan

Nowadays, the phenomenon of employee performance become a major concern for management around the world as it is a key element which influence organizational effectiveness and competitiveness in era of technological advancement. In understanding these key elements towards achieving success throughout the emergence of globalization, the main objective of this study is to analyze the relationship between workload, role conflict, supervisor support and co-worker support with employee performance among telecommunication employees, Jordan. Data was collected using questionnaire through convenience sampling technique. Total 285 questionnaires distributed to the employees; however, only 119 questionnaires have been successfully collected, and further used for the data analysis. For data analysis; SPSS version 25.0 has been used. From the research findings, it revealed that three (3) out of four variables having significant relationship with the employee performance, which are role conflict, supervisor support and co-worker support. As a recommendation, Telecommunication Company in Jordon need to ensure that all three variables (role conflict, supervisor support and co-worker support) which have significant relationship with the performance need to be managed successfully as to boost up their employees’ performance

The effects of Artemisia Sieberi, Achillea Fragrantissima, and Olea Europaea leaves on the performance and physiological parameters in heat-stressed broiler chickens

High temperatures have detrimental effects on the performance and physiology of broiler chickens. Medicinal plants have various biological activities and may enhance the heat resistance of chickens during heat waves. Therefore, this study aimed to explore the potential roles of using specific local medicinal plants to alleviate the negative impacts of heat stress (HS) in broilers. In this study, 180 day-old chicks were used to investigate the effects of HS and dietary indigenous medicinal plants on growth performance, antioxidant biomarkers, and intestinal health. The chicks were assigned to six groups (18 pens with 10 chicks per pen) with three replicates each. In the first group, the chicks were kept under thermoneutral conditions (CON) and fed a basal diet. The other five groups were exposed to recurrent heat stress and fed a basal diet (T1, HS group) or supplemented with Artemisia Sieberi (1.25 g/kg of feed; T2), Achillea Fragrantissima (15 g/kg of feed; T3), Olea europaea (10 g/kg of feed; T4), and all the previous additives (all-in-one) combined at the same dose levels mentioned above (T5). At 21 days of age, the chicks from each group were exposed to two phases of heat stress: phase 1 from days 21 to 34 (34 ± 1°C) followed by phase 2 from days 35 to 39 (37 ± 1°C). The results indicate that HS significantly increased rectal temperature and respiration rate in broiler chickens. Feed intake and body weight gain were improved in all supplemented groups, while the feed conversion ratio was decreased in response to the dietary inclusion of medicinal plants. Additionally, glutathione peroxidase and immunoglobulin G levels were increased in the T3, T4, and T5 groups compared to the other groups. HS induced significant upregulated in the mRNA levels of heat shock protein 70 and interleukin-8, while the mRNA of occludin was decreased. The T3, T4, and T5 showed significantly decreased expression of hepatic HSP70 and ileum IL-8 genes and increased ileum mRNA occludin levels relative to the CON and T1 groups. In conclusion, supplementation with these plants enhances growth performance and maintains intestinal health sustaining the productivity of broiler chickens under HS conditions

EFFECTS OF PREGNANCY AND DISEASE STRESS ON THE ANTIOXIDATIVE CAPACITY OF SHEEP AND GOAT

ABSTRACT Sheep and goat undergoes various stresses throughout their life cycle, among various causes of these stresses pregnancy and diseases are the most common one which widely affected these two ruminants. The aim of this study was to investigate the effect of pregnancy and disease stress on antioxidative capacity of the sheep and goat, which in turn screens the total health status of the animal under study. Forty goat and sheep females (20 each) in two groups viz 15 diseased & pregnant and 5 healthy females without pregnancy and diseases (control) were investigated for variations in the antioxidative capacity. Result of study revealed that acw value (the water soluble antioxidative capacity) was reported lowest in pregnant sheep (5.75mg/l), whereas this value was reported highest in the control group (7.08 mg/l) which concluded that stress caused by pregnancy or disease reduced the antioxidative capacity of goat and sheep as compared the control group. Similar trends were reported in the goat also

Effect of Maternal Water Restriction on Sexual Behavior, Reproductive Performance, and Reproductive Hormones of Male Rat Offspring

The present study aimed to investigate the effect of maternal water restriction on sexual behavior, reproductive performance, and reproductive hormones of male rat offspring. Forty pregnant female rats were divided into two equal groups: Control (C) and water-restricted (WR). Control dams had ad libitum water access throughout pregnancy, while dams in the WR group were subjected to 50% water-restriction from day 10 of pregnancy onwards. The maternal water restriction provoked a significant reduction (p < 0.05) in body weight of dams before delivery and at birth and litter body weights of offspring at birth. Maternal water restriction did not affect relative weights of reproductive and body organs of male rat offspring. All hormonal concentrations, sperm count, and vitality in male rat offspring were not significantly affected by maternal water restriction. Maternal water restriction exposure induced significant (p < 0.05) reduction in intromission latency, intromission frequency, and post-ejaculation interval in male rat offspring while a significant (p < 0.05) increase in the ejaculation latency was detected in maternal WR group. In conclusion, this study suggests that maternal water restriction had a negative impact on some reproductive characteristics but did not severely affect reproductive performance and reproductive hormones of male rat offspring

Effects of medical plants on alleviating the effects of heat stress on chickens

ABSTRACT: Over the past decades, global climate change has led to a significant increase in the average ambient temperature causing heat stress (HS) waves. This increase has resulted in more frequent heat waves during the summer periods. HS can have detrimental effects on poultry, including growth retardation, imbalance in immune/antioxidant pathways, inflammation, intestinal dysfunction, and economic losses in the poultry industry. Therefore, it is crucial to find an effective, safe, applicable, and economically efficient method for reducing these negative influences. Medicinal plants (MPs) contain various bioactive compounds with antioxidant, antimicrobial, anti-inflammatory, and immunomodulatory effects. Due to the biological activities of MPs, it could be used as promising thermotolerance agents in poultry diets during HS conditions. Nutritional supplementation with MPs has been shown to improve growth performance, antioxidant status, immunity, and intestinal health in heat-exposed chickens. As a result, several types of herbs have been supplemented to mitigate the harmful effects of heat stress in chickens. Therefore, several types of herbs have been supplemented to mitigate the harmful effects of heat stress in chickens. This review aims to discuss the negative consequences of HS in poultry and explore the use of different traditional MPs to enhance the health status of chickens
