Three phosphate solubilizing bacteria were isolated and identified by 16S rRNA sequencing as Pseudomonas putida, Pseudomonas sp and Pseudomonas fulva. The strains were subjected to plant biochemical testing and all the PGPR attributes were checked in the presence of pesticides (chlorpyrifos and pyriproxyfen). The phosphate solubilizing index of strain Ros2 was highest in NBRIP medium i.e 2.23 mm. All the strains showed acidic pH (ranges from 2.5-5) on both medium i.e PVK and NBRIP. Strain Ros2 was highly positive for ammonia production as well as siderophore production while strain Rad2 was positive for HCN production. The results obtained by the strains Rad1, Rad2 and Ros2 for auxin production were 33.1, 30.67 and 15.38 μg ml-1, respectively. Strain Rad1 showed 16% increase in percentage germination in comparison to control in the presence of pesticide stress. Most promising results for chlorophyll content estimation were obtained in the presence of carotenoids upto 6 mgg-1 without stress by both strains Rad1 and Rad2. Study suggests that especially strain Ros2 can enhance plant growth parameters in the pesticide stress.

سید اسد اﷲ کاظمی

سید اسد اﷲ صاحب کاظمی
افسوس ہے کہ مشہور ماہر تعلیم سید اسد اﷲ صاحب کاظمی نے کراچی میں انتقال کیا وہ مسلم یونیورسٹی کے نامور فرزند تھے حصول تعلیم کے بعد کچھ دنوں یونیورسٹی ہی میں انگریزی کے استاد رہے، پھر صوبہ متحدہ کے محکمہ تعلیمات سے وابستہ ہوگئے، اور ڈپٹی ڈائرکٹر کے عہدہ تک پہنچے، اسی زمانہ میں ریاست کشمیر کے ڈائرکٹر تعلیمات ہوگئے ملازمت سے ریٹائر ہونے کے بعد یونیسکو کی طرف سے کئی سال تک حکومت بغداد کے مشیر تعلیم رہے اس طرح ان کی پوری عمر تعلیمی تجربات میں گذری مسلمانوں میں وہ ماہر تعلیم مانے جاتے تھے، ان کو مسلمانوں کے تعلیمی مسائل سے بڑی دلچسپی تھی، اور اُن کی تعلیمی تنظیموں کو اپنے تجربات اور مفید مشوروں سے فائدہ پہنچاتے تھے، علمی و ادب کا بلند اور (ستھرا مذاق رکھتے تھے) مذہبی مطالعہ بھی وسیع تھا، راسخ العقیدہ پابند مذہب مسلمان تھے، کلام مجید کے مطالعہ کا خاص ذوق تھا، بغداد کے قیام کے زمانہ میں کچھ عربی بھی سیکھ لی تھی۔ اﷲ تعالیٰ نے اُن کو دین و دنیا دونوں سے نوازا تھا، عالم آخرت کی نعمتوں سے بھی سرفراز فرمائے۔ (شاہ معین الدین ندوی، نومبر ۱۹۷۱ء)

 

DIGITAL LITERACY AS A FOUNDATION FOR RELIGIOUS MODERATION LEARNING AT SALATIGA'S AL-HIJRAH TINGKIR ISLAMIC BOARDING SCHOOL

The current millennial generation, includes santri, who have digital literacy skills, but unfortunately it has not been matched by ability to use digital media to obtain information and self development. The purpose of the research was to determine the extent to which students’ digital literacy skills, how to use digital literacy as a basis for religious moderation learning, and the obstacles faced during the training on the use of digital literacy at the Al-Hijrah Islamic Boarding School Tingkir Salatiga. This research is a qualitative and participatory action research. Data collection techniques used are participant observation, interviews, and documentation. The data analysis technique uses Mile and Hubermen in the form of reduction, presentation, and conclusions. The research procedure includes planning, implementation, observation, and reflection. The result of the studi show that digital literacy can be used as a basis for learning religious moderation. The students at the Al-Hijrah Islamic Boarding School can get digital content in the form of religious moderation material from website, social media, and others. The students also take advantage of digital literacy to create religious moderation content.

Psychological Impact of Terrorism on Internally Displaced Women

The biggest dilemma of modern age is Terrorism. While on one side, terrorism has extinguished countless lives, left physical scars and psychologically hampered masses; on the other side it has also displaced millions of people. Vast literature on the effects of terrorism on mental health of people is available across cultures, but there are very few studies that have highlighted psychological impact of terrorism on internally displaced women. The present study is an endeavor to focus on the mental health of one of this neglected segment of society, in Pakistan. Studies on mental health of people affected by Terrorism worldwide, revealed high levels of post traumatic stress disorder as one of the major negative outcome of the trauma. However there are some recent studies that have highlighted some positive changes too that an individual may experience as a result of struggling with the trauma, called post traumatic growth (PTG). The present study investigated both the post traumatic stress disorder (PTSD), as well as the development of post traumatic growth( PTG) among internally displaced women (N=130) from Federally Administered Tribal Areas (FATA) who were living in the IDP camps. Furthermore, the researcher also examined the differences in PTSD scores of the respondents vis-à-vis their marital status, differences and severity of trauma resulting from loss of a family member or close relative/s. This study also explored the unique relationship of post traumatic stress disorder (PTSD) with post traumatic growth (PTG) and locus of control (LOC) among the sample. In addition to this, general mental health of the sample was also assessed along with its relationship with PTSD. Age range of the sample was16- 60 years (Mean age = 39.94, S.D = 13.95). Results indicated that majority of the sample had at least some symptoms of post traumatic stress disorder and slightly less than half of the sample (40.8%) met the diagnostic criteria of PTSD. Findings revealed a significant difference between married and unmarried women on PTSD scale, with married women obtaining significantly higher scores on PTSD scale as compared to unmarried respondents. Besides, bivariate correlation revealed that age was also strongly correlated with PTSD. Therefore, further analysis (ANCOVA) was conducted, controlling for women’s age. Our findings revealed that marital status was no longer significantly associated with PTSD symptoms. Further, though loss of family member/s did not reveal a significant difference in the scores of PTSD among the sample, yet it was observed that women who lost family member in terrorism scored relatively higher on PTSD scale. PTSD was negatively associated with PTGI in the preliminary analysis (r =-.14) but post hoc analysis when conducted, by regressing post traumatic growth (PTG) onto post traumatic stress symptoms ( PTSD), revealed a significant quadratic effect. Hence the study demonstrated a significant curvilinear relationship between PTSD and PTG. Respondents with fewer PTSD symptoms reported lower levels of growth, whereas respondents having moderate levels of PTSD symptoms exhibited higher levels of growth. Surprisingly when PTSD symptoms became severe, the growth levels dropped down. In this study the relationship of PTSD and locus of control (LOC) could not be verified as all the respondents rated themselves extremely high on God locus of health control scale (GLHC). In fact there was no variability in the scores on GLHC scale among the sample. Findings also revealed a strong positive correlation between General mental Health symptoms (GHQ) and PTSD. The present research on one side, provides a detailed analysis of PTSD and the factors that contribute toward PTSD among internally displaced women from remote areas of Pakistan, whereas on the other side it has also revealed positive outcomes following trauma: Post traumatic growth and its relationship with post traumatic stress disorder in a unique combination of terrorism and internal displacement.
