ABSTRACT Parathyroids of pregnant rats nephrectomized 24 hours before delivery on the 22nd day of pregnancy, show increased parathyroid activity. The foetal parathyroids are also enlarged and have an increased mitotic rate and there is a significant positive relationship between the foetal parathyroid volume and the serum phosphorus of the mothers. Hence it is reasonable to assume that the stimulus for the foetal parathyroids is the same as that for the mothers, i. e. the altered calcium-phosphorus homeostasis after nephrectomy.

ABSTRACT In non-insulinized alloxan diabetic pregnant rats an altered calciumphosphorus homeostasis was demonstrated and in addition morphological parathyroid changes occurred in the diabetic rats and their offspring. This was manifested by enlargement of the parathyroid glands and increased mitotic rate, suggesting parathyroid stimulation. The parathyroid volume in the offspring of the alloxan diabetic rats exhibited a significant negative relationship with the maternal serum calcium and a significant positive relationship with the maternal serum phosphorus. Hence it is reasonable to assume that the altered calcium-phosphorus homeostasis in the diabetic pregnant rats is responsible for the morphological changes in the foetal parathyroids.

ABSTRACT Geometrically increasing doses of cortisone (0.5, 1.5 and 4.5 mg twice daily) were injected into pregnant rats, and the volume, nuclear diameters and mitotic rate of the maternal parathyroids as well as the parathyroid volume and mitotic rate in the foetuses were determined. The nuclear diameters were if anything smaller and the mitotic rate tended to decrease in the cortisone treated groups. There were no significant differences between the parathyroid volumes of the foetuses in the control and cortisone-treated groups. Thus, it seems that the development of the rat foetal parathyroids and the morphology of the maternal parathyroids are little affected if at all, by cortisone.

Love is more than a close friendship. It acts as a major facilitator of interpersonal relationship. Love is positive in nature and leaves a positive affect on every individual. An individual in love not only feels positive but spreads positivity around. They smile, be kind to other people, behave compassionately with everyone. If the person is happy then he is likely to be psychologically and emotionally healthy. The current study aimed at understanding the relationship between love, affect and wellbeing among young females aged between 20-25 years. The study reported a significant positive relationship between love and positive affect with the significant correlation of 0.29 at 0.05 levels (p<0.05). It was also found a significant positive relationship between love and wellbeing with the significant correlation of 0.58 at 0.01 level (p<0.01). This means that people in love experience positive emotions and healthy wellbeing. The correlation between love and negative affect came out to be insignificant. The correlation turned out to be -0.13. This means that people in love do not experience negative emotions.

The 2 types of exchange relationship perceptions—social exchange relationship perceptions (SERPs) and economic exchange relationship perceptions (EERPs)—constitute the primary concept for understanding individual behavior in the workplace. Using a sample of 581 employees from Mainland China, I explored the effects of SERPs and EERPs on employee extrarole behavior (ERB), as well as the moderating effect of organization-based self-esteem (OBSE) on the relationships between SERPs and ERB, and between EERPs and ERB. The results revealed a significant positive relationship between SERPs and ERB, a significant negative relationship between EERPs and ERB, and a significant moderating effect for OBSE. Theoretical and practical implications of these findings are discussed.

Abstract In this research on the one hand we analyzed the relationship that exists in terms of motivational persistence and the Big Five dimensions and, on the other hand, organizational citizenship behavior (OCB). The results show that the conscientiousness has been identified as being in a significant positive relationship with OCB. This result is consistent with the data provided by previous researchers. The results also indicate that three conscientiousness facets are in a positive relationship with OCB. These three conscientiousness facets are self-efficacy, cautiousness and orderliness. Agreeableness was not identified as being associated with OCB. At the level of the relationship between motivational persistence factors and OCB, we have identified a significant positive relationship with only one factor: current purpose pursuing. The OCB model has two variables that work best as predictors: high scores with regard to current purpose in terms of the pursuing-motivational persistence factor, and low scores in terms of the imagination-facet of openness to experience.

Total dissolved solids (TDS) and chlorophyll a were not related in 25 lakes which were all off the Precambrian Shield. Both on-shield and off-shield lakes were included in the previous reports which showed a significant relationship between TDS and productivity. When data from on-shield and off-shield lakes were analyzed separately, there was no significant positive relationship between TDS and lake biomass or productivity. It was also shown that mean depth ([Formula: see text]) was as good a predictor of fish production as the TDS: [Formula: see text] ratio, the morphoedaphic index.Key words: TDS, biomass, productivity, morphoedaphic index, chlorophyll a, lakes

Present research was intended to examine the association between suicidal ideation and clinical anger among the physically disabled. The Purposive Convenient study was conducted at Artificial Limbs Centre, Fauji Foundation Hospital Rawalpindi from February 2016 to November 2016. The modified scale for suicidal ideation and the clinical anger scale were used for data collection. Sample comprised of 150 physically disabled individuals including 87 (56%) males and 63 (42%) females.  Findings revealed that suicidal ideation had significant positive relationship with clinical anger and females were significantly higher in clinical anger and suicidal ideation as compared to males. Furthermore,results revealed higher mean scores on clinical anger by the participants having the problem of spinal cord 26.10±9.25 and suicidal ideation is higher in persons having problem of polio 15.87±9.41as compared to other physical disabilities. The study highlighted the need develop and enhance mental and physical health. Continuous...

This study investigates the relationship between Foreign Direct Investment (FDI) and some macroeconomic variables such as Gross Domestic Product (GDP), Gross Capital Formation (GCF), Agriculture, Forestry, and Fishing (AFF), Industry, Import, Export, Inflation and Unemployment rate. Panel Data of 14 regional alliances countries from 1990-2018 were collected from The World Bank website. Robust regression models are used in this study. This research found that GDP had significant positive relationship with FDI in all regions except Arab League, EU and G7 countries. GCF had significant positive relationship with FDI in Arab League, BRI, GATT, NAFTA countries & negative relationship in APEC, G7 countries. AFF had significant positive relationship with FDI in BRICS, GATT countries & negative relationship in African Union, ASEAN, BIMSTEC, BRI, BRICS, SAFTA countries. Industry had significant positive relationship with FDI in African Union, BRI, NAFTA, OECD countries and negative relationship in BRICS, G7, G20 countries. Import had significant positive relationship with FDI in African Union, APEC, Arab League, ASIAN, BRI, G7, G20, GATT countries and negative relationship in BRICS countries. Export had significant positive relationship with FDI in BRICS countries and negative relationship in African Union, ASEAN, BRI, G20, GATT, OECD, SAFTA countries.

The production of cereals, including rice, wheat, and maize has increased in China over the past 20 years. However, variations in the production and cultivated area of cereals remains unclear. In this study, we collected and analyzed the cereal production and cultivated area in China from 1998 to 2016. An 85% increase in cereal production was recorded from 1998 to 2016, due to an increase in the maize production along with the increase in the cultivated area. Meanwhile, rice and wheat production have been stable since 2000. No change occurred in the rice cultivated area through 2016, and a 19% decrease in the wheat cultivated area was observed in 2016 relative to 1998. In addition, a significant positive relationship was observed among cereal production, maize production, and cultivated area (p < 0.0001). Together, the increase in cereal production in China over the past two decades has resulted from the increase in maize cultivated area and the consequent increase in maize production.
