Thirty-six species of epilithic brown algae, with multicellular, foliaceous and thalloid organizations belonging to three classes, three orders, four families and fifteen genera of the phylum Phaeophycota have been collected from Manora, Hawkesbay, Buleji and Paradise Point, the coastal areas near Karachi (Pakistan) during March 2006 and June 2010. They were morphologically investigated, identified with the help of existing literature and taxonomically described. As a result of that three new species viz. Iyengaria nizamuddinii, Spatoglossum shameelii and S. qaiserabbasii were discovered and eleven species were described for the first time from the coast of Pakistan. The occurrence of Padinopsis is its first record of growth in the Indian Ocean. In the previously described species, several new characters and taxonomic variations were recorded. Later on the collected species were investigated anatomically in detail. For this purpose, the thalli were first studied in surface view. Then cross sections (CS) were obtained from apical middle and lower parts of the thalli and microscopically examined to understand mode of growth and morphogenesis of thallus. Wherever possible, the CS and longitudinal sections (LS) of stipe, holdfast or heptron were obtained, in several cases the marginal portion of the thalli were also studied. The anatomy of fertile parts was investigated to understand reproductive structures, their development and pre-fertilization changes. The information obtained was compared with the previously published descriptions and discussed in each species. In most of the cases new and much detailed information was obtained and several new anatomical features were discovered.

نیل کنارے دو دل ہارے

نیل کنارے دو دل ہارے

مصری نوجوان ان دو شخصیات کے ممنون ہوں نہ ہوں دریائے نیل کی ممنونیت سے انکار نہیں کر سکتے ۔دریا کے کنارے سرکار نے بیٹھنے کے لیے خوبصورت اور آرام دہ جگہ بنائی ہے یہاں نیل کی تازہ ہوا کے جھونکے کی سر مستی میں یہ نوجوان لڑکے اور لڑکیا ں ایک دوسری سے محبت کی پینگیں بڑھاتے ہیں ۔مصر میں مرد و زن کے اختلاط پرکوئی سرکاری یا سماجی پابندی نہیں عورت اپنی زندگی کا ساتھی بڑے اعتماد کے ساتھ نا صرف چن سکتی ہے بلکہ اس کا اظہا بھی برملا کر تی ہے ۔ میرے خیال میں شاید ہی کسی دوسرے مسلم ملک میں عورت کو یہ اختیار حاصل ہو جو مصری عورت کو حاصل ہے ۔دریائے نیل کے کنارے جوان جوڑوں کی بیٹھک دریا کے حسن میں اضافے کا موجب بنتی ہے ۔مصری لڑکیاں جدید مغربی لباس کے اوپر خوش رنگ کوٹ زیب تن کر کے اور سر پر دوپٹے کی جگہ سکارف پہنے انتہائی جاذبِ نظر دکھاتی دیتی ہیں ۔تھوڑے تھوڑے فاصلے پر بیٹھے ان جوڑوں کے درمیان سوڈان او ر دوسرے غریب افریقی ممالک کی خواتین گھومتی نظر آتی ہیں جو ہاتھوں میں خوش رنگ گلدستے لیے ان محب اور محبوب کی خوش گپیوں میں مخل ہو کر رنگ میں بھنگ ڈال کر مطالبہ کرتی ہیں کہ ہم سے پھول خرید کر اپنے دوست کو پیش کرے ۔میں نے سوڈانی خاتون سے پوچھا کہ دن میںکتنے گلدستے فروخت کرتی ہو ،بولی دن اچھا ہو تو سو جنین کے پھول نکل جاتے ہیں میں نے  دکتور محمود سے پوچھا کہ آپ نے کبھی کسی کے ساتھ نیل کے کنارے پر لطف وقت بتایا ہے ،بولے ہائے میرے نصیب میری غربت اس راہ میں بڑی رکاوٹ ہے ۔میں نے پوچھا اس پر لطف وقت کے لیے...

The Issue of Human Cloning: A Review in Semitic Religions’ Context

Human cloning has emerged as a new and innovative technology in the reproductive and therapeutic science in the recent past. So far it has not been practiced over human beings but owing to its huge potential and possible scope, it has attracted the attention of not only the masses (particularly the infertile couples and LGBTQs etc) but the other stakeholders including the religious scholars from worlds’ prominent religions have given their views on this technology in order to guide their followers. This paper examines and reviews the religious points of view on human cloning. For this purpose, three Semitic religions in the world i-e Judaism, Christianity, and Islām have been examined. As far as Islam is concerned, this portion has been divided into two broad sections elaborating the Shī‘ah and Sunnī schools’ opinions. Being an innovative topic, the religious teachings do not address it directly hence the injunctions related to the reproduction are most relevant to it. Three Semitic religions have been examined from the perspective of admissibility or non-admissibility of human cloning, the rationale behind the verdict on human cloning and the possible solutions to the issues and problems faced by the followers in the case of acceptance or rejection of this biomedical technology. Most of the religions emphasize over adaptability of the natural mode of reproduction only, where male and female genders contribute to the reproductive cycle. The Semitic religions reject the reproductive cloning generally. The religious experts need to conduct more focused and updated research before coming to any conclusion about the permissibility or non-permissibility of this technique.

Comparatrive Study of a Male and a Female School Principal: Exploring Their Gender Related Views and Practices of Task Delegation

Gender and leadership has been an area of concern for researchers working in the field of gender based educational inequalities. "Gender inequality in education constructs and, in turn, is constructed by inequalities between men and women in other spheres that intersect with education" (Subrahmanian, 2005, p. 9). The provision of equal opportunities in education has been a major concern for the researchers (Khalid & Khan, 2006; Ashraf, 2007; Aslam, 2009; Ghaffar, 2011). Ashraf (2007) has highlighted the need for developing gender equality perspective for secondary school teachers, which could ascertain the growth of students as gender-aware individuals. The present qualitative study has attempted to explore the gender related views of a male and a female school principal and their practices of task delegation through comparative analysis using Sergiovanni's (1991) framework and a gender lens. The data were collected through semi-structured interviews, observations (through shadowing), post observation discussions and document reviews. Miles and Huberman's (1992) framework guided the data analysis. The study has used gender lens to explore the analyzed data, which is then reviewed through Sergiovanni's (1991) framework. This framework helped in identifying the views symbolized as "Heart" of the leaders as key elements informing their practices presented as the "Hand". The study revealed that the "Head" that symbolizes meaning making of leadership responsibilities with a gender lens was the missing element in participants' professional repertoire as a school encompassing "hand" dimension of this framework. The key findings of the study show that the participants' practices of task delegation to male and female staff were guided by their views and past experiences of gender. It also showed that the absence of professional training on gender was the reason for their lack of insights into how gender guided their practices. The study suggests professional courses and sessions based on gender studies to build the principals' understanding of key gender constructs and how these inform their practices and demonstrate gender informed leadership. The gender informed leadership practices will hold significance in the provision of equal opportunities for male and female staff as well as students at a single school level to the whole educational system. Further, the study recommends the researchers to explore other aspects of principals' decision making such as conflict resolution, motivation and staff appraisals with a gender lens.
