The present research was primarily aimed to adapt, translate, and standardize WISC-IV for Pakistan. The research was conducted in collaboration with NCS Pearson Private Limited, India as part of a larger project aiming at standardization of WISC-IV for South Asia. Research process was completed through three studies. Study-I was concerned with the adaptation and translation of WISC-IV and it was completed through two phases. Phase I involved pre-testing of the original WISC-IV South Asia subtests (n=12). Its findings not only identified few items needing adaptation but also suggested translation of instructions and/or item content of all subtests (including performance subtests). Phase II was concerned with the steps involved in proper adaptation and translation of the WISC-IV subtests. It involved a priori procedures (judgmental procedures) for adaptation and translation of the subtests. These procedures included multiple-forward translation, committee approaches, and expert reviews. This process resulted in development of Urdu adaptation of WISC-IV in which child directed instructions for all subtests and item content of all verbal subtests have been translated into Urdu along with various adaptive changes. Study II was aimed to evaluate the psychometric properties of the WISC-IV PAK through conduction of tryout I (n=33), tryout II (n=88), and tryout III (n=110). Initial tryout assessed functioning and comprehensibility of items through response frequency and reliability analysis only. But other two tryouts involved Classical Test Theory (CTT) and Item Response Theory (IRT) based psychometric techniques to improve, item reliability, item difficulty, item discrimination, and item fit. This detailed item analysis v involved item re-ordering of nine subtests and changes in item content and/or sampled responses of few other subtests and resulted in finalization of WISC-IV PAK. The study III involved the standardization of the WISC-IV PAK and was completed through four phases. All the analyses conducted in this study are based on a normative sample of 800 children (50% girls) selected through following a stratified random sampling design. The normative sample was stratified into 11 age groups, two gender groups, five geographical regions, and three parental education levels. It was selected from govt., semi-govt., and private schools and colleges situated in 10 districts of Pakistan. In the first phase of study III, subtests temporal stability and internal consistency evidence was established. In the phase II a multi-model multi-trait matrix method was utilized to establish convergent and discriminant validity of WISC-IV PAK. The cross validation of WISC-IV factorial structure in Pakistan was also done during this phase. Pakistani norms for WISC-IV PAK were developed for 11 age groups of one year ranging from 6 to 16 years and 11 months in the phase III of the standardization study. Two types of norms including standard score norms (scaled scores and composite scores) and test-age equivalent norms were derived. Comparison of WISC-IV PAK composite scores by using Pakistani and UK norms was also conducted in this phase. In the last phase of study III influence of variables like age, gender, geographical region, and parental education level on children’s intelligence level was explored. This concluded the efforts to provide a reliable and well-standardized tool to measure intelligence of Pakistani children.

ہو ملاقات جو اپنوں سے یا اغیار کے ساتھ

ہو ملاقات جو اپنوں سے یا اغیار کے ساتھ
کتنا اچھا ہو اگر سب سے ملیں پیار کے ساتھ

تو نے منصور بڑی دار کو عزت بخشی
ذکر ہوتا ہے تو ہوتا ہے ترا دار کے ساتھ

میں تو بس دُور ہی رہتا ہوں ہمیشہ ان سے
میری بنتی جو نہیں زر سے نہ زردار کے ساتھ

آسرا حشر میں آقا کی شفاعت ہو گی
کون واں ہو گا بھلا مجھ سے خطاکار کے ساتھ

مجھ کو منظور فقط تیری رفاقت جو ملے
نہ رہے کوئی تعلق مرا سنسار کے ساتھ

ساتھ تیرے بھی وہی ہو گا یقینا تائبؔ
جو کہ ہوتا ہے یہاں ایک وفادار کے ساتھ

Syed Ali Tarmizi and Akhun Darwaiza: Mughal Agents or Popular Saints

The Sixteenth century proved an eventful period with regard to the Mughal-Pakhtūn relations in the north-western borderland region. Besides the political tug of war it witnessed a clash of religious nature between the two Ṣūfī saints of the area namely Bāyazīd Anṣārī and Syed ‘Alī Tirmidhī Aliās Pīr Bābā. Settled in the pre-dominantly anti-Mughal Pakhtūn abode Bāyazīd Anṣārī was an opponent of the Mughals in his political orientation in religious jargon. Pīr Bābā challenged his Ṣūfic interpretation based on the Waḥdat al-Wūjūd concept of Islamic mysticism. Their confrontation of mystic traditions gave birth to a debate that whether Pīr Bābā had confronted Bāyazīd for religious reasons or he was working for the interests of the Mughals. The present article aimed at to investigate the matter and to establish a factual position. It would further be explored to understand the nature and contents of the conflict that whether it was religious or otherwise.

Yield and Chemical Composition of Castor Bean Ricinus Communis L. As Influenced by Environment

Castor bean (Ricinus communis L.) locally known as “arind” or “arindi” is non- edible oilseed crop with enormous significance having almost 700 uses. Keeping in view the potential of castor as a cash crop, a study was carried out to investigate germination rate index (GRI) of different cultivars, optimum sowing date and appropriate seed source for adaptability, stand establishment and suitability under diverse environmental conditions of Pothowar (Pakistan). For the purpose, a hypothesis was developed “Castor bean can be economically beneficial cop of Pothwar region” To evaluate this hypothesis, three types of experiments including in vitro experiments, sowing date and seed source trials were conducted. In vitro experiments were of two types. In the first experiment, the seed of four castor bean cultivars (DS-30, PR-7/1, PR-101, Local) was conditioned to different moisture levels i.e. 0, -700 and - 1400 kPa under different temperature levels (10, 15, 20, 25, 30 and 35°C) in growth chamber to determine germination rate index. The results showed that GRI of cultivars differed significantly on the basis of temperature and moisture levels. The cultivar DS- 30 showed the highest GRI value followed by PR-101 and minimum value for Local cultivar. All the cultivars showed a downward trend for germination at 10°C and 15°C at -1400 kPa osmotic pressure. In the second experiment, seed of commercial cultivar, DS-30 was collected from three different locations of Bahawalpur, Faisalabad and Tandojam and tested under same temperature and moisture levels as in first experiment. Germination rate index differed significantly with respect to seed sources as well as temperature regimes. Maximum germination rate index was observed in the Faisalabad seed source followed by the Tandojam seed source, while the Bahawalpur seed source xxishowed the lowest germination rate index value. As regards moisture levels, the highest GRI value was noted in 0 kPa (control) while minimum at -1400kPa. Regarding field trials, the same four cultivars as used in in vitro trial, were sown in July and August during 2004 and 2005 with four sowing dates (15 th July, 30 th July, 15 th August, 30 th August) at three locations (Islamabad, Attock, Chakwal). The cultivar DS-30 had greater emergence percentage, plant height, seed yield, number of capsules plant -1 , seed weight plant -1 , 100-seed weight and yield ha -1 than the other cultivars. Similarly the crop planted in July gave significantly better results compared to August sowing. The cultivar DS-30 had higher oil content, oil yield, palmitic acid and linoleic acid, whereas ricinoleic acid was comparable to other cultivars. The highest value for ricinoleic was found in Local cultivar. To determine the better seed source for Pothowar Plateau, DS-30 seed produced under different temperature and rainfall patterns (Faisalabad, Tandojam, Bahawalpur) was tested in the second field trial at same three locations as used in sowing date trial. Faisalabad seed source performed better regarding most of the growth parameters as compared to others. Tandojam seed source crop produced higher oil content and protein percentages compared to the rest of seed sources. However, seed source has a nominal effect on oil content, protein percent and fatty acid profile. As castor been cultivation in Pakistan has been on a regular decline since 1979, its cultivation is now restricted to marginal areas of the country and Pothwar region of Punjab. In order to revive its cultivation, it was imperative to conduct an ex ante economic analysis with other competing crops of the area to examine its diffusion potential in Pothwar region. Moreover, the relative success of castor bean cultivation in different parts of the region was also carried out to assess its potential at different xxiirainfall zones of the area. Our findings show that castor bean cultivation can be a profitable option for farmers as a kharif crop provided it is planted at optimum time (July) along with high yielding cultivar (DS-30). Stability analysis of four castor bean cultivars over three locations revealed that PR-101 is the stable cultivar at all three locations of Pothowar although its yield was comparatively lower than DS-30. However, DS-30 can also be appropriate cultivar for all the locations especially Islamabad and Attock as its yield was highest among the cultivars.
