No full textThe intention to share: professionals’ knowledge sharing behaviors in online communities
No full textSince the 1990s, the rise of some online communities as well as the decline of others has caught the attention of academia as well as of practice. One assumption for the decline of some online communities is the lack of the rich knowledge content that is believed to be the source of competitiveness and sustainability of any online community. Online communities are increasingly acknowledging the value of knowledge and the knowledge sharing processes required for online communities to build and sustain their identity in this competitive and constantly changing online environment. This research aims to provide an understanding of knowledge sharing behavior through the adaptation of two major theories imported from Social Psychology: the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TpB). Exploring knowledge sharing from a social psychological perspective provides an understanding of the process an individual goes through to make the decision to share his/her knowledge with others as well as the different psychological factors facilitating or hindering knowledge sharing behavior. Research findings are based on a web-survey of 158 group members, and an observation of interactions of eight active groups in one online community of professional educators. Proposing an extended theoretical model of knowledge sharing behavior in an online community, this research found that normative pressures, including subjective norms and descriptive norms, had a strong influence on the formation of the individual’s intention to share in the online community. Knowledge sharing self-efficacy also was found to significantly account for explaining the individual’s motivation to share his/her knowledge with other members. Attitude and controllability were not found to have significant impacts on the formation of intention. The qualitative analysis of the interactions of members of eight active groups revealed that there were other implicit factors that motivated individuals to engage in online activities. The observation of 24 online sessions had generated beliefs related to knowledge sharing behavior. Those beliefs were related to normative beliefs and the pressure created by the expectations of others, control beliefs and the confidence of the individual’s ability to behave, and finally, behavioral beliefs and individual outcome expectations.Ph.D.Includes bibliographical referencesIncludes vitaby Bibi M.

By Ameena Bibi, Assistant Prof, Department of Urdu, International Islamic University, Islamabad
Urdu Dictionary Board (UDB) has compiled and published Urdu’s most comprehensive dictionary, titled Urdu Lughat: Tareekhi Usool Par (Urdu Dictionary: on historical principles). While appreciating the monumental work, the author of this paper has pointed out certain lacuna in the way many of the entries in Urdu Lughat published by UDB are explained. The author has also compared the explanatory wordings in UDB’s dictionary with some other dictionaries of Urdu and has explained what and which is correct and what errors have been committed by UDB editors. Although she is all-praise for the work, she has objectively evaluated some portions of UDB’s dictionary in the light of lexicographic rules
Xylan deterioration approach: Purification and catalytic behavior optimization of a novel β-1,4-d-xylanohydrolase from Geobacillus stearothermophilus KIBGE-IB29
No full textThe β-1,4-d-xylanohydrolase is an industry valuable catalytic protein and used to synthesize xylooligosaccharides and xylose. In the current study, β-1,4-d-xylanohydrolase from Geobacillus stearothermophilus KIBGE-IB29 was partially purified up to 9.5-fold with a recovery yield of 52%. It exhibited optimal catalytic activity at pH-7.0 and 50 °C within 5 min. Almost 50% activity retained at pH-4.0 to 9.0 however, 70% activity observed within the range of 40 °C to 70 °C. The β-1,4-d-xylanohydrolase showed a significant hydrolytic pattern with 48.7 kDa molecular mass. It was found that the enzymatic activity improved up to 160% with 1.0 mM ethanol. Moreover, the activity of enzyme drastically increased up to 2.3 and 1.5 fold when incubated with Tween 80 and Triton X-100 (1.0 mM), respectively. The β-1,4-d-xylanohydrolase also retained 72% activity at −80 °C after 180 days. Such a remarkable biochemical properties of β-1,4-d-xylanohydrolase make it possible to forecast its potential use in textile and food industries.

Full text linkPerselingkuhan dalam keluarga akan merusak sendi-sendi rumah tangga. Oleh sebab itu, pencegahan perselingkuhan perlu diupayakan. Berkaitan dengan hal tersebut, yang menjadi permasalahan dalam penelitian ini adalah a) analisis struktur dalam Hikayat Bayan Budiman; b) gambaran isi cerita sisipan dalam Hikayat Bayang Budiman; c) makna simbolik dalam Hikayat Bayan Budiman sehingga mampu mencegah seseorang berselingkuh. Penelitian ini bertujuan mengetahui struktur (penokohan, alur, latar) bingkai utama dan cerita sisipan dalam Hikayat Bayan Budiman; mengetahui gambaran isi cerita sisipan dalam Hikayat Bayang Budiman; mengetahui makna simbolik Bari cerita sisipan yang secara sistematis mengupayakan pencegahan perselingkuhan dalam keluarga. Sebagai salah satu penelitian sastra, penelitian ini menggunakan metode kualitatif yang bersifat deskriptif. Selanjutnya menggunakan pendekatan struktural sebagai langkah awal untuk mengetahui keberadaan tokoh-tokoh dalam Hikayat Bayan Budiman. Kemudian pendekatan semiotik untuk mengetahui makna simbolik dalam Hikayat Bayan Budiman. Hasil penelitian ini menunjukkan dari analisis struktur yang meliputi penokohan, alur, dan latar memperlihatkan bahwa tokoh Khojah Maimun digambarkan sebagai sosok yang tampan, pandai, dan bijaksana; sedangkan Bibi Zainab sebagai wanita yang cantik, tergoda laki-laki lain, tetapi dapat dicegah Burung Bayan; Burung Bayan memperlihatkan sosok burung yang mempunyai wawsan luas, bijaksana, tempat curahan hati Bibi Zainab. Adapun rangkaian peristiwa menampakkan pengenalan, konflik, per unitan, klimaks, dan peleraian. Mengenai latar memperlihatkan adanya latar tempat dan suasana yang mendukung peristiwa yaitu bahagia, marah, gelisah, dan cemas. Gambaran cerita sisipan memperlihatkan sisi kehidupan yang dihadapi manusia sehari-hari, terutama menyangkut masalah keluarga yang meliputi kesetiaan, kemandirian, kepalsuan, dsb. Makna simbolik yang muncul adalah perselingkuhan dapat disebabkar oleh rasa sepi, kerinduan, kesempatan, martabat dan kekayaan lebih tinggi. Hal itu dapat dihindari apabila disikapi dengan bijaksana dan ditunjukkan baik buruknya perselingkuhan, kebahagiaan yang abadi dalam keluarga, rasa saling percaya, saling menghargai, dan saling mencintai

Perception of Secondary School Teachers Towards the Transformational Leadership for Teachers' Effectiveness
Full text linkThe main aim of this study was to identify the perception of
secondary school teachers towards transformational leadership styles among their principals for teachers' effectiveness. The transformational
leadership factors consist of idealised influence attribute and behaviour,
intellectual stimulation, individualised consideration and inspirational
motivation. The study was conducted in ten secondary schools in the
Kuala Pilah, Jelebu and Jempol district. A total of 235 teachers were
selected by using a simple random sampling method.
Statistical analysis such as descriptive, percentage, means scores
and Pearson correlation test were carried out. The findings revealed that
the principals 'sometimes' exhibited idealised influence attribute (X = 2.35) and behaviour, 'sometimes' provided inspirational motivation (X=2.59),
and 'sometimes' (X=2.59) utilised intellectual stimulation in executing
tasks to teachers. The results also proved principals in KPJJ district 'once
in a while' give individualised consideration (X= 1.89) to their teachers.
Correlational analysis indicated that principals' idealised influence
attribute, idealised influence behaviour, inspirational motivation,
intellectual stimulation and individualised consideration were related to
teachers' effectiveness. This means that the relationship between the four
factors of transformational leadership and teachers' effectiveness were
positive and moderate. The higher the principals displayed
transformational leadership styles the higher will be teachers' effectiveness
in their performance
