Environmental Efficiency Analysis of Basmati Rice Production in Punjab, Pakistan: Implications for Sustainable Agricultural Development
The intensive use of chemicals worked as a catalyst to shift the production frontier but the most critical factor of maintaining a clean environment was totally ignored. The present study attempts to estimate the environmental efficiency of rice production by employing the translog stochastic production frontier approach. The data are collected from five major Basmati rice growing districts (Gujranwala, Sheikupura, Sialkot, Hafizabad, and Jhang) of Punjab in 2006. Chemical weedicides and nitrogen are treated as environmentally detrimental inputs. The mean technical efficiency index is sufficiently high (89 percent) but the environmental efficiency index of chemical weedicides alone is 14 percent while the joint environmental efficiency index of chemical weedicides and nitrogen is 24 percent implying that joint environmental efficiency is higher than chemical weedicide alone. It indicates that substantial reduction (86 percent) in chemical weedicide use is possible with higher level of productivity. Moreover, it is likely to contribute a considerable decrease in environmental pollution which is expected to enhance the performance of agriculture labour. The reduction in chemical weedicides will save Rs 297 per acre and Rs 1307.3 million over all from the rice crop in Punjab, improving the profitability of rice growing farmers by the same proportion. Empirical analysis indicates that reduction in environmental pollution together with higher level of profitability in rice production is achievable.Rice Production, Environmental Efficiency, Weedicide, Fertiliser (NPK), Stochastic Translog Frontier
The Effect of Supply Chain Integration, Management Commitment, and Sustainable Supply Chain Practices on Non-profit Organizations Performance Using SEM-FsQCA: Empirical Evidence in Afghanistan
This study investigates the impact of supply chain integration, management
commitment, and sustainable supply chain practices on non-profit organization
performance. The research, centered on non-profit organizations in Afghanistan,
employs Structural Equation Modeling (SEM) and Fuzzy-set Qualitative
Comparative Analysis (FsQCA) to untangle intricate connections, involving a
sample size of 169 participants. The findings suggest that integrating the supply
chain positively affects sustainable practices, emphasizing the role of consistent
integration in enhancing overall performance. Moreover, higher management
commitment leads to improved supply chain performance. Additionally, supply
chain challenges significantly influence non-profit performance, underscoring the
importance of efficient supply chain management in enhancing overall
organizational performance. The FSQCA of Non-Profit Organization Performance
(NPOS) identified critical factors contributing to positive outcomes, including
Supply Chain Practice (SSCP) and Management Commitment (MC) with high raw
coverage values. The Integration of Supply Chain (SCI) combined with the absence
of Supply Chain Challenges (SCC) demonstrated strong links to positive outcomes,
highlighting the importance of overcoming challenges within an integrated supply
chain framework and providing valuable insights for non-profit organizations

ANALISIS KOMPARATIF PEMUTUSAN KONTRAK KOMERSIAL DI AFGHANISTAN DAN INDONESIA
Penelitian ini mengkaji pemutusan kontrak komersial di Afghanistan dan Indonesia.
Penelitian ini menggali implikasi hukum pemutusan kontrak di Afghanistan dan
Indonesia, memberikan wawasan berharga bagi praktisi, pembuat kebijakan, dan
akademisi hukum komersial. Afghanistan dan Indonesia memiliki sistem hukum
yang berbeda, terbentuk oleh sejarah, budaya, dan politik masing-masing.
Meskipun keduanya mengakui hukum Islam, Afghanistan memiliki lanskap yang
berbeda dengan latar belakang sosial politik yang rumit dan iklim ekonomi yang
berubah dengan cepat. Hukum kontrak komersial berkaitan dengan pembuatan,
pelaksanaan, dan penegakan kontrak. Hal tersebut melibatkan kesepakatan antara
dua pihak atau lebih untuk pertukaran barang, jasa, atau hak keuntungan. Penelitian
ini menggunakan pendekatan hukum normatif legislatif untuk menganalisis
pemutusan kontrak di Afghanistan dan Indonesia, dengan memeriksa kategori
hukum, literatur terkait, serta undang-undang dan sumber-sumber otoritatif untuk
pemahaman aturan kontrak bisnis. Kontrak komersial di Afghanistan dan Indonesia
dapat diputuskan jika berakhir karena force majeure. Di Afghanistan, kontrak dapat
dibatalkan jika ditetapkan oleh pengacara tak berwenang, sedangkan di Indonesia,
pemutusan kontrak harus diputuskan oleh hakim. Pembatalan kontrak komersial di
Afghanistan dan Indonesia bisa menimbulkan kewajiban hukum seperti
pengembalian keadaan semula, pembayaran ganti rugi, atau pemulihan kerugian.
Konsekuensinya bervariasi tergantung pada faktor kasus dan hukum yang berlaku
Passive immunization against highly pathogenic Avian Influenza Virus (AIV) strain H7N3 with antiserum generated from viral polypeptides protect poultry birds from lethal viral infection
Our studies were aimed at developing a vaccination strategy that could provide protection against highly pathogenic avian influenza virus (AIV), H7N3 or its variants outbreaks. A purified viral stock of highly pathogenic H7N3 isolate was lysed to isolate viral proteins by electrophresing on 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), followed by their elution from gel through trituration in phosphate buffered saline (PBS). Overall, five isolated viral polypeptides/proteins upon characterization were used to prepare hyperimmune monovalent serum against respective polypeptides independently and a mixture of all five in poultry birds, and specificity confirmation of each antiserum through dot blot and Western blotting. Antiserum generated from various group birds was pooled and evaluated in 2-week old broiler chicken, for its protection against viral challenge. To evaluate in-vivo protection of each antiserum against viral challenges, six groups of 2-week old broiler chicken were injected with antiserum and a seventh control group received normal saline. Each group was exposed to purified highly pathogenic AIV H7N3 strain at a dose 105 embryo lethal dose (ELD50). We observed that nucleoprotein (NP) antiserum significantly protected birds from viral infection induced morbidity, mortality and lowered viral shedding compared with antiserum from individual viral proteins or mixed polypeptides/proteins inclusive of NP component. The capability of individual viral polypeptide specific antisera to protect against viral challenges in decreasing order was nucleoprotein (NP) > hemagglutinin (HA) > neuraminidase (NA) > viral proteins mix > viral polymerase (PM) > non-structural proteins (NS). Our data provide proof of concept for potential utilization of passive immunization in protecting poultry industry during infection outbreaks. Furthermore conserved nature of avian NP makes it an ideal candidate to produce antiserum protective against viral infection

Survival benefit of surgery in recurrent glioblastoma multiforme
There is an ongoing debate regarding role of surgery for recurrent glioblastoma multiforme (GBM). Older literature hinted at only modest survival benefits with surgery and a high rate of morbidity. However, more recent literature suggests better survival that may be attributed to better surgical techniques and better options in adjuvant treatment. Herein the authors review recent literature with regards to the possible role of surgery in recurrent GBM and also look into the key factors impacting second surgery
Typologies of didactical strategies and teachers’ pedagogical beliefs : a theoretical review
Didactical strategies are one of the most influential vehicles that directly contribute to transforming knowledge. Varying types of didactical approaches are being adopted and implemented in the preparation of future teachers in the initial teacher education set up. The current conceptual paper is based on rigorous literature review on the typologies of didactical strategies adopted in the initial teacher education. The purpose of this conceptual and theoretical study is to evaluate and contrast varying didactical approaches while navigating through literature. The study also aims at exploring the interrelationship of didactical approaches with teacher cognitions i.e., teacher pedagogical beliefs. The methodology of this study based on the selection of six types of didactical strategies by Van De Grift (2007) and to compare and contrast them with other typologies available in literature and to explore the interrelationship with teachers’ pedagogical beliefs. The study concludes that the varying typologies of didactical strategies are being adopted and implemented in the ITE set up and these strategies have strong relationship with teacher’s pedagogical beliefs. The study recommends that the teachers’ cognitions i.e., teachers’ pedagogical beliefs may be included in the curriculum when preparing future teachers in the initial teacher education setting. These findings are substantial for policy makers, curriculum developers, head teachers, and other stakeholders in the initial teacher education
