The main objectives of this work were to investigate physico-chemical and heavy metal contaminations in water and sediments as well as their accumulation, histopathology and genotoxicity in Freshwater mussels of River Kabul. For this purpose water sample A (reference site 1), water sample B (polluted site 2), water sample C (polluted site 3) and water sample D (polluted site 4) upstream and downstream of River Kabul were collected during winter and summer periods and analyzed for eight physico-chemical parameters (pH, TSS, TDS, TA, Cl, K, EC, Na) and nine heavy metals (Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Zn) and compared with water sample A and NEQS recommended limits. All the studied physico-chemical and heavy metal parameters in water samples A, B, C and D except TSS andHg were below the NEQS proposed limits, where the values of TSS and Hg were above the NEQS recommended limits in all the water samples A, B, C and D. Thus the overall sequence of different water samples was D > C > B > A. This highlights that water sample D had higher and sample A had lower physico-chemical and heavy metal contaminations. Water samples A and B had highest TDS and lowest K for low flow and had highest TSS and lowest K for high flow seasons. Similarly water samples C and D showed highest TDS and lowest pH for low flow and showed higher TSS and lower K for high flow periods. Among heavy metals water sample A had highest Zn and lowest Cr for both summer and winter seasons. Water sample B showed higher Zn and lower Cu for summer and greater Zn and smaller Hg for winter seasons. Similarly water samples C had greater Zn and smaller Cu for both summer and winter seasons. Similarly water samples D had higher level of Zn for summer and greater Zn and lower Hg for winter seasons. Similarly among the studied heavy metals in sediments sample A had highest Fe and lowest Hg for both summer and winter seasons. Sediments sample B, had highest concentration of Fe and lowest concentration of Hg for both summer and winter seasons. Similarly sediments sample C had highest Fe and lowest Hg for both summer and winter seasons. Similarly sediments sample D had highest concentration ofFe and lowest concentration of Hg for both summer and winter seasons. This investigation was further aimed to determine bioaccumulation of heavy metals including Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn in soft tissues of freshwater mussels.Overall order of metals concentration in different tissues showed that Fe was the highly and Hg was the lowest accumulated metals. This study was further meant to investigate histopathological impacts of heavy metals in soft tissues were degeneration of epithelium, lipofusin pigments, atrophy, inflammation, necrosis and granulocytoma in digestive gland. In gonads necrosis, inflammation, atresia, lipofusin pigments and granulocytoma were found. While in gills the degeneration of cilia, fusion of gills lamellae, haemocytic infiltration and gills swelling was recorded. Similarly in intestine degeneration of epithelium and its cillia were found. The highest intensity of histopathological lesions was recorded in site 4 and lowest in site1. Furthermore the present investigation was conducted to assess genotoxical impacts of heavy metals in hemolymph of selected freshwater mussels. Therefore degree of DNA damage like TCS and comet class 0, class 1, class 2, class 3 and class 4 were determined. The order of sites according to DNA damage was 4 > 3 > 2 > 1, i.e. the highest DNA damage was noticed in site 4 while lowest in site 1.

مرشد دا شہر

مرشد دا شہر
(آنحضور صوفی محمد اصغر سائیں رینجرز آف جہلم شریف والوں کی یاد میں )

سیّو مینوں دیو ودھائیاں جہلم شہر نوں میں جے چلی
خوشیاں ہوئیاں دون سوائیاں میں تے جاندی پئی ہاں کلی

سیاں کرن روانہ آئیاں نالے روون وانگ سودائیاں
ماہی ہن کیوں دیراں لائیاں ، انہاں نوں دیوے کون تسلی

جہلم شہر دے کوچے گلیاں ، ڈھونڈ رہی میں تھکیاں تلیاں
پارس(۱) پیر دے در آ کھلیاں ،مینوں لوکی کہندے جھلی

دلبر دے میں دیس نوں جاواں اوتھے جاکے شکر مناواں
درد دلے دے رج سناواں ، عشقے دی اے چوٹ اَولی

دید تیری نوں ترسن سیاں ، ہجر سزا میں کٹ دی پیاں
ہوئیاں اج سہاگن جنھاں راہ ہمیش سجن دی ملّی

قادری عشق چبارے چڑھیاں اوہ نہ فیر گھراں نوں وڑیاں
جہلم جا اوہ درس چ پڑھیاں، انہاں نوں چٹھی مرشد گھلی

(پارس پیر: صحابی رسول جن کا دربار جہلم دریا کے کنارے پر ہے)

The Relationship Between Competence and Job Satisfaction on the Performance of Private Madrasah Tsanawiyah Teachers in the City of Surabaya

This study aims to discuss the relationship between competence and job satisfaction on the performance of private Madrasah Tsanawiyah teachers in the city of Surabaya. The research method used is the type of research used that is explanatory with a quantitative approach with a sample size of 244 of 628 teachers from 44 private Madrasah Tsanawiyah in the city of Surabaya). The results showed that teachers’ competence had an effect on teachers’ job satisfaction with a value of 0.184. Teachers’ competence affected teachers’performance with a value of 0.118. Teachers’ job satisfaction affected teachers’ performance with a value of 0.222. Teachers’ job satisfaction on teachers’  performance showed a high influence with a CR value of 2.772 (greater than 2.00) and a significance level (p-value) of 0.006 (less than 5%). It can be concluded that teachers’ competence affected teachers’ job satisfaction and teachers’ competence affected teachers’  performance. Teachers’ job satisfaction had a strong effect on teachers’ performance.

The Role of Formal Education in the Alleviation of Poverty in Khyber Pakhtunhwa A Case Study of Khyber Pakhtunkhwa, Province of Pakistan

This study: ‘The role of formal education in alleviation of poverty is a case study of Khyber Pukhtunkhwa’. It is a comparative study of literate and illiterate respondents from slum areas of KP which evaluates the role of formal education in poverty alleviation by comparing the socio-economic status of both types of respondents, their personal views and thinking, their involvement in decision making process, their importance or triviality in the family and their participation in community matters. This research study develops an understanding of the educational benefits and human capital approach that can be used to enhance literacy for people especially for poor. The research is based on the importance of education in promoting free education as a constitutional right by comparing the socio-economic status and other contributing factors of literate and illiterate respondents. As a way of determining the benefits of education can offer. The main objectives of this research were to study illiteracy as cause of poverty, the causal link of education and poverty alleviation, its impact on the socio-economic status and comparison of literate and illiterate respondents with their views about availability of free education in KP province. The major hypothesis developed for this study was that higher literacy rate among people has greater potentials to combat poverty. For this purpose an interview schedule was drafted in accordance with research study objectives. The interview schedule consisting of sixty five questions was used as a tool to get information from the respondents. Eight hundred respondents i.e. four hundred illiterate and four hundred literate respondents (who were basically from the same slum areas but their socio-economic status improved as a result of education) were selected according to Warwick P.D and Linger C.A (1975, pp 69- 110) formula f = n / N through various sampling techniques the details of which have been given in chapter-3 of Research Design. The data collected was analyzed and tabulated and standard statistical tests of significance were used. The results were collected through a series of phases delivered across both types of respondents studied. These being: total monthly income, number of children, affordability of different types of diet and health and education services, point of views about importance of education, benefits of education, factors responsible for accelerating poverty and knowledge about free secondary education as a constitutional right and its availability for poor people. The main purpose of the study was to evaluate the socio-economic status of literate and illiterate respondents; in order to understand if education impacts human poverty. Furthermore, education was investigated as a human capital approach to accelerating human knowledge and skills and raising earning outcomes in KP province. The results of the study supported the hypotheses of the study. The comparative status of both the literate and illiterate revealed that high percentage of literate respondents were in the high income groups. This positively affected their living conditions. Majority of them were now living in pucca/concrete houses. The study also revealed that various other indicators, such as access to different types of diets, affordability of medicines and quality medical care, children education, participation in family and community matters and development activities confirmed improvements in the socioeconomic status of the literate respondents. While majority of the illiterate respondents were living in kacha/mud houses. During the process of this study, the researcher explored that largely due to illiteracy and poverty the illiterate respondents were unable to give education to their family members or children. Because they could not afford the cost of education and the family members were compelled to find some form of work to enhance their family’s incomes. Resultantly when such family members start practical life they are likely to form poor households because they lack sufficient income earning capacity due to inadequate human capital which becomes a cause to perpetual transmission of poverty from one generation to the next. “Human Capital” theory served as a theoretical framework of the study was tested for its validity through findings of the research study. Based on the findings of the research study, the researcher offers some key workable recommendations and a new model for the improvement of existing formal education system, its relevance, effectiveness and access to free secondary education in the province.
