Associations Among Self-Compassion, Eating Behaviors, and Stress in College Freshmen
Get PDFPurpose: Few studies have investigated the potential relationship between self-compassion and eating behaviors. Self-compassion has been shown to improve one’s ability to respond more effectively to various situations and stressors by embracing the constructs of self-kindness, common humanity and mindfulness. This study examined correlations between self-compassion, eating behaviors and stress in first-time college freshmen.Methods: First-time freshmen (N=1477), ages 18-22 years (63% female), self-reported measures of Perceived Stress Scale (PSS), Three-Factor Eating Questionnaire (TFEQ), and Self-Compassion Scale (SCS). Associations among PSS, SCS and TFEQ scores were examined with Pearson correlations by gender. Differences by gender were explored with t-tests.Results: There were significant (p < 0.01) correlations between disinhibition and negative SCS constructs (self-judgment, r = 0.29; isolation, r = 0.23; over-identification, r = 0.28) and restraint and self-judgment in females (r = 0.26). Females scored significantly higher than males on PSS and negative SCS subscales (p < 0.05).Conclusion: Interventions increasing self-compassion and reducing stress may optimally support psychological and behavioral wellbeing as students transition into college. Future research needs to understand how self-compassion interventions may attenuate the inimical cycle of dietary restraint and disinhibition in university students
Allelopathic Impact of Sorghum and Sunflower on Germinability and Seedling Growth of Cotton (Gossypium hirsutum L.)
Get PDFSorghum and sunflower are considered as highly allelopathic plants with inhibitory efficacy on plants of other species. In a pot study, the phytotoxic potential of sorghum and sunflower shoot and root on germination and seedling growth of cotton was evaluated through soil incorporation of powders and spray of water extracts. The experiment was conducted at | department of Agronomy, Sindh Agriculture University Tandojam during Kharif (summer) 2010 and 2011. The analysis of pooled data suggested that all the powders and water extracts of both allelopathic crops caused substantial suppression of germination and related traits of cotton seedlings as compared to control (untreated). Sorghum shoot powder (10 g kg-1 soil) caused highest allelopathic effects and reduced cotton seed germination by 12.8%, root length by 45.4%, shoot length by 51.9%, fresh weight seedling-1 by 41.7% and dry weight seedling-1 by 36.7%, followed by sunflower shoot powder (10 g kg-1 soil) in phytotoxic efficiency for inhibiting seed germination, seedling growth and weight in contrast to control (untreated). Sorghum showed superiority over sunflower in allelopathic efficiency. Powder of both crops was found more allelopathic in contrast to water extract. Among plant parts phytotoxic potential, shoot proved higher in inhibitory effect than root. However, it was concluded from the results of present study that both sorghum and sunflower possess allelopathic compounds with growth suppressing ability which could be utilized for effective weed management in cotton under field conditions as eco-friendly low-cost alternate of herbicides with wise strategy
The Status and Prospects for Agriculture in the United Arab Emirates (UAE) and their Potential to Contribute to Food Security
Get PDFThis paper focuses on the status and prospects for food production in the United Arab Emirates (UAE) and the government’s role in sourcing food to feed its people. Food security is an international issue even for those countries that have fertile soil, adequate water, and a skilled farm labor force. This is evident in the UAE, with its harsh environment, limited water resources, and infertile soil. In recent years, and as a result of the mega-development in its infrastructure and its economic activities, the UAE received more than eight million people from more than 200 ethnicities worldwide. They have not only been seeking better jobs and better life, but also with the intention to settle permanently. Their growth in the UAE population alerted the government to look for alternatives to increase food supplies other than from imports. Focusing on its local farms, and exploring the suitable new farming techniques, will bring more prosperity to the farming sector in the UAE
Enhanced Mechanical Properties of Organo-Clay Based UHMWPE Nanocomposite Films
Get PDFThe proposed study investigated the effect of organo-clay contents in ultra-high molecular weight polyethylene (UHMWPE) gel/solution cast films. The organo-clay was loaded in the range of 1 to 5 % (wt. / wt.), based on polymer content, to prepare UHMWPE nanocomposite films. The UHMWPE nanocomposite films were drawn up to 15 times below their melting point. Un-drawn and drawn UHMWPE nanocomposite films were subjected to mechanical and optical characterizations. The enhanced modulus (> 170 % higher than un-drawn films for 5 % organo-clay loadings at draw ratio of 15) and higher force at break (about 150 % higher than un-drawn films) without the loss of inherent optical transparency, even at higher organo-clay loadings, are reported. The findings in this study will broaden the engineering applications of UHMWPE nanocomposite films
