Examination and comparison of psychological characteristics of american football players and handball players

In this study, mental toughness and anxiety have been chosen to be compared between male American football and handball players. The present study was carried out to determine and examine the psychological parameters mentioned above and show the importance of these concepts in the process of sport career. Mental toughness (with its sub-dimensions) and anxiety levels of 44 male participants were determined. Twenty-seven of those participants were American football players between 19 and 25 years of age (mean ± s: age 20.93 ± 2.25 years). Their sports experience ranged between 1 and 19 years (mean ± s: 10.26 ± 3.34 years). The remaining seventeen participants were handball players between 18 and 26 years of age (mean ± s: age 21.54 ± 3.31 years). Their sport experience ranged between 5 and 12 years (mean ± s: 9.15 ± 4.13 years). Differences between the groups were determined using the "Independent Sample t-test" analysis method using the SPSS 21.0 software. The independent sample t-test results showed that there were significant differences in the total mental toughness (including its sub-dimensions; confidence, constancy and control) and anxiety levels of the two group of players (p < .05). The American football team players’ confidence, control, and total mental toughness levels were higher than that of handball players and they had lower level scores for constancy and anxiety levels. © 2018 by authors, all rights reserved

Suitability of calorie fortified diets for improving the production of Clarias gariepinus broodstock and fry

The findings are presented of an experiment conducted to determine the adequate level of calorie in diets that is necessary to bring Clarias gariepinus female broodstock to grand stage. The effect of different calorie level on the quality and quantity of egg produced by C. gariepinus broodstock and the survival rate of the fry fed the same diets and those fed harvested zooplankton were also investigate

From drawing board to dining table: the success story of the GIFT project

As compared to crops and livestock, the genetic enhancement of fish is in its infancy. While significant progress has been achieved in the genetic improvement of temperate fish such as salmonids, no efforts were made until the late 1980s for the genetic improvement of tropical finfish, which account for about 90 percent of global aquaculture production. This paper traces the history of the Genetic Improvement of Farmed Tilapia (GIFT) project initiated in 1988 by the WorldFish Center and its partners for the development of methods for genetic enhancement of tropical finfish using Nile tilapia (Oreochromis niloticus) as a test species. It also describes the impacts of the project on the adoption of these methods for other species and the dissemination of improved breeds in several countries in Asia and the Pacific.GIFT, Tilapia culture, WorldFish Center, Genetics Oreochromis Niloticus

ENVIRONMENT, HUMAN HEALTH AND SAFETY PERSPECTIVES TO PRIVATE SECTOR PARTICIPATION IN AGRICULTURE

Agriculture, unlike industrial activity which has always resulted in pollution, has been environmentally benign for most of its history until after the Second World War when the system disintegrated. Then, crop residues were incorporated into the soil or fed to livestock, the manure returned to the land in amounts that could be absolved and utilized. Mechanized farming, however, is reliant on synthetic fertilizers and pesticides. Hence, crop residues and livestock excreta, which were once recycled have become wastes and their disposal a continuing problem for the farmer. With the present national policy on agriculture, there is the need for private sector participation especially in the area of environmental health and safety for economic and environmental sustainability.Environmental Economics and Policy, Farm Management, Health Economics and Policy,

The growth and survival rate of (private) Oreochromis niloticus fingerlings fed with varying percentages of Leucaena leucocephala leaf meal based diets

A-ten-week feeding trial was carried out to evaluate the growth and survival rate of Oreochromis niloticus fed with varying percentage levels of Leucaena leucocephala leaf meal as a substitute for groundnut cake. The levels in the various diets were 0% - Diet 1, 25% - Diet 2, 50% - Diet 3 and 75% - Diet 4. Ten fingerlings with an average weight of 0.44g were stocked at the rate of 10 fish per bowl and fed at 5% body weight. Diet 1 with 0% inclusion of leucaena leaf meal gave a significant difference (P>0.05) in growth and survival rate compared with diets 2, 3 and 4. The water quality parameters recorded were appropriate for fish cultur

Fish genetics research in member countries and institutions of the International Network on Genetics in Aquaculture: Proceedings of the Fifth Steering Committee Meeting of INGA

A conference proceedings of the Fifth Steering Committee Meeting of the International Network on Genetics in Aquaculture (INGA), this publication incorporates information drawn from aquaculture genetics research undertaken or in progress in member countries and associate member institutions of INGA. The papers in this publication examine progress in aquaculture genetics research in developing countries and identify areas for possible collaboration between institutions in developing and developed countries towards developing better breeds of fish that can contribute to increased production and food security while ensuring the conservation of aquatic biodiversity.Fishery resources, Genetics, INGA, Information networks, ICLARM, SEAFDEC, FAO, Bangladesh, China, Cote d'Ivoire, Egypt, Fiji, India, Indonesia, Malawi, Malaysia, Philippines, Thailand, Viet Nam, Israel, UK, Netherlands,

Impact of capital on the growth process of a sugarcane farm in Mpumalanga

The research was conducted for a representative 50 ha farm in the Onderberg region in Mpumalanga province, where farmers use a combination of centre-pivot, drip, and dragline systems of different sizes to grow sugarcane. The main intention was to establish a multi-period linear programming model capable of economically evaluating a farm's expansion decision-making process for farmers faced with investment decisions in alternative irrigation systems, taking into account the available initial capital of the farm. A linear programming (LP) model was used to assign a mainline for a total of twelve irrigation system combinations based on the assumption that the farmer wishes to start with a 30 ha centre-pivot investment. The Generalized Algebraic Modelling System (GAMS) was used to formulate the farm growth model as mixed integer dynamic linear programming (MIDLP) for a 15-year planning horizon. Based on the results, farmers are initially forced to invest in lower-cost irrigation systems when they lack capital to start a farm business due to the time value of money. They only consider lowering operating costs by investing in capital intensive irrigation systems when they have more own capital or borrowing capacity.Agricultural Finance,
