EXPLORING SUPPLY DYNAMICS IN COMPETITIVE MARKETS

Understanding the ebb and flow of competitive markets is essential for students pursuing a variety of undergraduate degrees. The objective of this study is to introduce users to interactions that occur in the supply side of competitive markets using a dynamic simulation model with curriculum materials.Marketing,

Agency Theory Issues in the Food Processing Industry

The objective is to identify significant determinants of performance for food processing firms over the 1992 to 2003 time period, focusing particularly on the issue of family control. Variables measuring firm effects such as asset size, governance, income distribution, and risk are used to explain return on equity. This study builds upon previous research by including a measure of income distribution in the food processing industry. Governance variables are found to be significant determinants of return on equity. The results found no evidence of agency problems in family-controlled firms during this time period.agribusiness, institutional economics, organizational economics, Agribusiness, Food Consumption/Nutrition/Food Safety, Production Economics, D23, G34, Q13, Q14,

Attitudes and reported practice of paediatricians and child psychiatrists regarding the assessment and treatment of ADHD in Ireland

Objectives. This mixed-method national survey has obtained original data on attention deficit hyperactivity disorder (ADHD) attitudes, assessment and treatment regimes reported by paediatricians and child psychiatrists; and has compared their clinics. It has examined the extent of involvement of Irish paediatricians in the management of ADHD. Methods. A questionnaire was designed, based on a review of literature and ADHD guidelines, and piloted by expert clinicians. Universal recruitment was conducted among Child and Adolescent Mental Health Services (CAMHS) consultants (n = 71) and community/general paediatric consultants (n = 72). Quantitative and qualitative data was collected and analysed. Results. There was an overall response rate of 43%. A dedicated ADHD clinic is offered in 79% of CAMHS services, but only in one paediatric service. Participants reported that the assessment of ADHD involves multidisciplinary work and this was only established in CAMHS clinics. Medication is initiated by 82% of child psychiatrists and only 22% of paediatricians. Conclusions. This first national study of ADHD attitudes and practices presents comprehensive data regarding the management of children with ADHD in CAMHS and paediatric settings in Ireland. Paediatricians reported a minor role in managing ADHD. Study limitations are related to subjective reporting rather than case note audit, and a moderate response rate for the paediatricians’ participants

Nuclear burst plasma injection into the magnetosphere and resulting spacecraft charging

The passage of debris from a high altitude ( 400 km) nuclear burst over the ionospheric plasma is found to be capable of exciting large amplitude whistler waves which can act to structure a collisionless shock. This instability will occur in the loss cone exits of the nuclear debris bubble, and the accelerated ambient ions will freestream along the magnetic field lines into the magnetosphere. Using Starfish-like parameters and accounting for plasma diffusion and thermalization of the propagating plasma mass, it is found that synchronous orbit plasma fluxes of high temperature electrons (near 10 keV) will be significantly greater than those encountered during magnetospheric substorms. These fluxes will last for sufficiently long periods of time so as to charge immersed bodies to high potentials and arc discharges to take place

Influence Of Tomato Yellow Leaf Curl Viral Infection On Antioxidant Content In Tomato (Lycopersicon Esculentum)

Tomato (Lycopersicum esculentum) is one of the most significant and extensively grown vegetable crop all over the world. Tomato Leaf Curl Viral disease is one of the key viral diseases leading to loss in productivity across the country. Antioxidants existent in plants play a vital role in this defence. In order to understand the basis of the tolerance study of the variation in the level of antioxidants in tomato against viral infections was necessary. Our study therefore focuses on analysing the influence of TLCV infection on variation in antioxidant content in tomato plants. Various antioxidants including alkaloids, ascorbic acid, total phenol, saponin and flavanoids were compared in healthy controls and TLCV infected tomato cultivars for a period of 30 days post inoculation. Previous reports suggest an increase in the antioxidant content in tomato plants in response to bacterial and fungal infection. The mechanism of host plant tolerance to various infections consists of a series of changes in biochemical events. This study reveals significant increase in the amounts of antioxidants post infection with ascorbic acid showing maximum rise
