Exploring Critical Factors Influencing Sustainable Food Consumption: A Conceptual Review (Published)

Sustainable food consumption is consumption of foods/diets that meets the dietary needs of man, the society, environment, economy and culture. Everyday great amounts of food are produced, processed, transported by the food industry and consumed by us. Hence, a comprehensive model of determinants of the sustainability of consumption is developed and applied to food consumption. When discussing the problem of unsustainable consumption, there is a need to focus on consumers’ behavior towards the decision making process. The sustainability of food consumption depends on individual consumer choices, but these individual choices are severely constrained by a range of factors. This paper is an attempt to profile these factors that affect sustainable food consumption. In addition, a research model is drawn up to aid further studies in this area.

Comparison of Zooplankton Community Structures in three Polyculture Models of Ponds Stocking Ctenopharyngodon Idellus (Published)

The Zooplanktons community structures in three polyculture models of pods, stocking mainly grass carp (Ctenopharyngodon idellus) were enumerated. We focused on the variability of a zooplankton community structure and compared its differences in the three polyculture models. Environmental factors and zooplankton abundance differed significantly among models. Nevertheless, model 2 had the minimum biomass of crustacean and zooplankton. Statistical analysis revealed that, NO2–N, COD, NO3–N, T, DO, PO43–P and pH are the most important environmental variables acting on the zooplankton assemblage. The differences in community structure of zooplankton and the growth rate of fish in the three Polyculture models showed that the model 2 was the most reasonable and efficient culture method, and Paddlefish (Polyodon spathula) can make more valuable contributions to market demand than bighead carp (Aristichthys nobilis).

Nature of Language, Speech and Communication Disorders (Review Completed - Accepted)

Speech, language and communication disorders are most common form of disorder among children in the world. The speech and language disorders are classified as expressive language disorder, phonological disorder, and communication disorder not-otherwise-specified (DSM-IV), mixed receptive-expressive language disorder and stuttering. Each category of speech and language impairment is prevalent among children from 5-15%. These disorders are mainly heritable and thus their genetic factor plays an important role in influencing these disorders. Genetic basis behind this defect is studied thoroughly in this review. Literature findings have showed that the main genes responsible for speech and language disorders are FOXP1 and FOXP2 genes which are identified through genome study linkages and genomic screening. Further research is required to UN reveal the biological pathways behind this deficit and to improve the treatment methods. Though various genetic factors play a vital role, other environmental factors also influences the speech and language disorders. The environmental factors must be considered importantly during childhood who already has genetic risk disorder. The important environmental influences related to children’s success or failures in reading are mainly educational experiences and home environment. Children’s literacy is mainly gained through the effect of home environment and through their oral language skills and reading comprehension ability when compared to accurate reading. Children who have such disorders must receive assistance from the speech-language pathologist. Speech-language pathologists work with children, families and schools to assist a child’s communication. This therapy can be useful to children all through their educational trajectory for the understanding of language, vocabulary and reading which is more complex. Their transition must be from learning to employment along with the children.

Using Least Squared Method To Estimate The Magnitude Of Various Environmental Sources Of Variation Influencing Birth Weight In Lohi Sheep Breed (Review Completed - Accepted)

Data on 3984 lambing records of 1285 Lohi ewes kept at the Livestock Experimental Station, Bahadurnagar, Okara for the period 1980-2011 were analyzed by using Harvey’s Mixed Model Least Squares and SPSS Computer Programme. The purpose was to estimate the magnitude of various environmental sources of variation influencing birth weight in this breed of sheep. The least squares mean for birth weight was 3.60± 0.03 kg. The trait was significantly (P< 0.01) & (P< 0.05) influenced by the year and season of birth, type of birth and the sex of the lamb born. The age of the dam also had significant effect on birth weight of the lamb; the younger ewes produced lighter (3.48 ± 0.03 kg) lambs than older ewes (3.69 ± 0.03 kg)
