IMPACT OF A MORE INTENSIVE INSECT PEST INFESTATION LEVEL ON COTTON PRODUCTION: TEXAS HIGH PLAINS

This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests.Crop Production/Industries,

MILK SUPPLY RESPONSE IN DELAWARE

Milk supply response by dairy farmers in Delaware was analyzed employing d1stnbuted lag price structures for number of milk cows and milk production per cow. A polynominal distributed lag model is fitted to quarterly data with deflated prices for the period 1966 to 1978. The variations in the number of milk cows is explained by about 98 percent. Farmers react positively to milk prices after l-2 years, while wages and feed prices have a negative impact on cow numbers. Milk production per cow shows positive adjustments to milk prices after 6 to 15 months. Technology and feed prices influence also milk production (R l =.87). While the short-run price elasticity of milk production is only .2, the long-run aggregate elasticity grows to 2.8 percent. Intermediate-run projections of milk supply were also performed with the model

Tidal river sediment management–A Case Study in Southwestern Bangladesh a case study in southwestern Bangladesh /

The problems of severe drainage congestion and waterlogging in the southwestern Bangladesh have been solved by an innovative concept, Tidal River Management (TRM). TRM involves the uniform raising of the land inside a tidal basin (beel) while simultaneously maintaining the proper drainage capacity in the river. The present practice of TRM is to link the river with the selected beel by constructing a link canal at the entrance of which most of the sedimentation takes place. This localized sedimentation also creates drainage congestion and water logging making it unattractive to landowners who participate in the program. In this paper a functional sediment management plan is presented to get rid of this problem

Dataset: Does loneliness, self-esteem and psychological distress correlate with problematic internet use? A Bangladeshi survey study

Background: Researchers have claimed that problematic internet use (PIU) and internet addiction (IA) is a global mental health problem. However, little research has addressed this issue in Bangladesh and no previous study has examined the relationship between PIU and potential psychological risk factors. Aim: The present study examined the prevalence of PIU and its associated risk factors including socio-demographic variables, internet use behaviors, and other psychological variables including loneliness, self-esteem, and psychological distress. Methods: A cross-sectional study was conducted among Bangladeshi students (N = 605). Measures included the Internet Addiction Test (IAT), Rosenberg's SelfEsteem Scale, the UCLA Loneliness Scale, and the General Health Questionnaire. Results: Using a cut-off score of ≤60 (out of 100) on the IAT, the prevalence of PIU was 16.5% (n = 100). Regression analysis showed that sleep disturbance (more or less than 6-7 hours sleeping time), not using internet for academic purposes, and online chatting were risk factors for PIU. Loneliness and psychological distress were positively correlated with PIU, whereas self-esteem was negatively correlated. Conclusions: The present study highlights that PIU among Bangladeshi university students is an issue of concern and that targeted prevention is needed among emerging adults to help overcome the potentially negative effects of problematic internet use
