ABSTRACT: This study attempts to investigate the relationship between perceived organizational justice (distributive, procedural, informational and interpersonal) and personality characteristics (conscientiousness and agreeableness) with counterproductive work behavior (CWB). The statistical population comprised of all personnel of Isfahan Power Distribution Company. The sample included 121 people, selected randomly by clustral sampling manner and response to the Colquitt’s organizational justice questionnaire, NEO personality questionnaire and Bennet and Robinsonʼs counterproductive work behaviour scale. Results indicated that there is a negative significant relationship between four facets of organizational justice and two dimensions of personality characteristics with organizational oriented CWB and interpersonal oriented CWB. Regression analysis showed that predictive variables were able to predict 34% of organizational oriented CWB and 32% of interpersonal oriented CWB and informational justice was the best predictor of two dimension of counterproductive work behaviour. The results indicated that the manners that increase personnel’s perceived justice and respect to the personality characteristic in personnel selection have an important role in decrease of counterproductive work behaviour.

J. Life Sci. Biomed., 3(4): 273-276, 2013.

ABSTRACT: Before the emergence of Islam, Arabs did not know anything about arts and Sciences (except for poetry and Lecture). However, after the defeat of Iranian Kingdom, due to their longer presence in Iran, the Arabs were attracted to the culture and civilization of Iran. Iranians with their civilized and cultural background immediately forgot the defeat and helped with the Sciences, techniques and thoughts. This way, they took the initiatives and brought the Sciences and techniques which, Arabs were not aware of, into the Islam; Sciences such as medicine, astronomy, music, architecture, mathematics and arts. Iranians started to compile, translate and teach the books to their students. The present article which covers the first period of the reign of the Abbasid, based on the historical documents, discusses the way Arabs got familiar with Iranian sciences and it studies the influence and spread of these sciences into the world of Islam and Moslems.

ABSTRACT: The purpose of this study is to investigate the simple and the multiple relationships between self-regulated learning strategies and motivational learning strategies, and procrastination and academic performance among the male first grade high school students in Boushehr. The participants are 300 (n=300) male first-graders, collected by random sampling method from all of the high schools in Boushehr during 1387-1388 year. The means of this study are: the Self-Regulated Learning Strategies Scale (SLSS) the Motivational Learning Strategies Questionnaire (MLSQ), the Tackman Procrastination Test, the General Self-efficacy Questionnaire (GSE), the Test Anxiety Inventory (TAI), and the Schwarzer, Smiths & Dihols Procrastination Scale. In order to analyse the data, statistical methods of simple correlation coefficient and multivariable regression have been used. According to the regression analysis, among the self-regulated learning strategies, which are the predictors of academic performance, only the self-consequence strategy is a predictor of academic performance. In addition among the self-regulated learning strategies which are the predictors of procrastination, the learning strategies of note review, self-evaluation, self-consequence and textbook review are efficient respectively. Moreover among the motivational learning strategies, which are the predictors of academic performance, the motivational strategies of self-efficacy intrinsic values, and test anxiety are efficient respectively. Also, among the motivational learning strategies the variables which are the predictors of procrastination, motivational strategies of intrinsic values, test anxiety, self-regulation and self-efficacy are the efficient ones respectively.

ABSTRACT: One of the most important functions of the nuclear family concerning which most of the sociologists have sympathy is the generation of cultural social identity where a new-born as a biological creature is raised by his/her family as a person with a cultural social identity that is made of his/her own society’s social behaviours and cultural elements. One of the influential factors in this process is the social stratification of families. The performance of children is somehow affected by their family background, and their social class and conditions. Since the differences between different social classes have remained considerable, in this research, we tried to study the relation between families’ social stratification and the quality and form of children socialization in The Children of Heaven script by Majid Majidi who directed The Children of Heaven successful movie in 1990s based on it. Documentary and textual analysis methods were used for data seeking and data mining, respectively. The results of this research showed that the patterns of raising the children were closely correlated to the social stratification. If the complementary social institutions especially schools do not make a way to upgrade the quality of the socialization of the children belonging to lower social classes, the application of popular education methods in these classes will lead to the continuance of the reproduction of class structure and social stratification. In order to improve family life, internalize the equal distribution of roles in a family, and reducing the reoccurrence of gender discrimination, it is necessary that children are socialized without considering their gender and according to their special characteristics and intentions.

ABSTRACT: This study was an attempt to examine psychometric properties, reliability, and validity of a test of reading comprehension for fourth grade elementary school students in Firouzabad, Iran. The target population of the study included (458 male and 464 female) fourth grade elementary school students in the 2010-2011 school year selected by census method. The measurement instrument included a reading comprehension test developed based on the abilities of fourth grade elementary school students and from extracurricular materials so that the test can measure the student’s actual ability in reading comprehension. Reliability of the test was estimated to be 0.86 after removing one of the items. Experts and experienced teachers’ views were sought for validity analysis and content validity of the test was confirmed. Furthermore, after examining criterion validity of the test, a correlation analysis was made between the students’ scores in reading comprehension and their scores in two courses: ‘let’s read’ and ‘composition’. The correlation coefficient for the relationship between the reading comprehension test both ‘composition’ and ‘let’s read’ was the same, i.e., 0.56 and meaningful at 0.001 level of significance. Based on the results obtained in the main implementation of the test, students’ mean score was 20/50 with the standard deviation of 0.36. The results of the t test showed that there was no meaningful difference between male and female students in test performance in reading comprehension. Factor analysis was also used for examining test dimensions. For this purpose, principal component (PC) analysis was used. Analysis of the scree plot showed that from the 6 factors, the first factor explained a higher percentage of the variance compared to other factors.

ABSTRACT: Biotoxicity of two plant powders; Piper guineense (Schum and Thonn) and Zingiberofficinale was investigated to ascertain their efficacies as sustainable and eco-friendly pesticides against fish beetles, Dermestes maculates. Eight dosages, 0.02, 0.04, 0.06, 0.08, 0.05, 1.0, 1.5 and 2.0 all in grams (g) were used in the assay and larval and adult mortalities monitored in two distinct experiments after 24 hours, 48 hours and 72 hours. Piper guineense powder at 2.0g gave mortalities of 83.33% and 76.67% for larva and adult respectively. In Zingiberofficinale, larval and adult mortalities of 76.67% and 73.33% respectively were obtained at 2.0g. There was 150% and 106.7% larval and adult emergence respectively when the smoked catfish (Clariasgariepinus) was treated with P. guineense powder. Similarly, when the fish was treated with Z. officinale, there was 166.7% and 156.7% larval and adult emergence respectively. The percentage weight losses were 0.15% and 0.35% for larvae and adults respectively in fish treated with P. guineense and 0.45% and 0.90% for larvae and adults respectively in fish treated with Z. officinale. The LD50 values were 28.3mg and 130.5mg for larva and adult respectively in fish treated with P. Guineans while the LD50 for larva and adult in Z. officinale treated fish were 66.2mg and 258.8mg, respectively. P. guineense was also observed to more toxic than Z. officinale, thereby ranking higher in storage potentialities. The plant materials could play a sustainable role in protecting the main source of protein in local food menu as well as foster development in bio and socio-economic values of the occupational areas.

ABSTRACT: Water samples from the Anambra River were taken from five distinct locations that displayed differential environmental stress to evaluate freshwater pollution. The physico-chemical characteristics of the river were conducted. The distribution and occurrence of heavy metals, which may affect human health and possibly induce aquatic damage, were investigated in the water column, adopting standard ecological and chemical techniques. The experimental approach was conducted under 2x5 factorial in a completely randomized block design using equal replicates to test the effects of season (rainy and dry) and location on the pollution parametric measurements, together with their interactions on heavy metal concentrations. Public survey on the use and treatment of water from the ecologically stressed river was investigated with questionnaire. Variations occurred between physico-chemical parameters and heavy metal concentrations of water samples from different locations in both rainy and dry seasons. Season by location interaction affected the heavy metal concentrations adversely, especially with regard to zinc. Likert scaling procedure further showed significant use and non-treatment of water from the river, posing a potential health threat to the dependent human population. Being obvious from the results that freshwater pollution could also be traceable to effluent/municipal wastewater discharged from industries and homes, there is need to respond appropriately to sustain the aquatic resources and avert possible human disease tragedies. In addition, Ackerman’s principles of water management for people and environment should be followed.
