Authorship conflict in Bangladesh: an exploratory study

This study aimed to explore the causes, types, and consequences of authorship conflicts among the researchers of selected research institutions in Dhaka, Bangladesh; and to suggest ways to reduce conflicts. A sample of 100 researchers was given a semi‐structured questionnaire; 45 subjects responded. The responses were confidential and anonymous. Over two‐thirds of the respondents were aware of authorship conflicts, and one‐third had actually faced conflicts with their co‐authors. Of them, four faced conflicts with their juniors, while 13 faced conflicts with their seniors or supervisors. The primary causes of such conflicts appear to be unethical claims of authorship, violation of authorship order, and deprivation of authorship. In most cases, the victims became frustrated and had to give up, and avoided a direct clash to safeguard their job. Four respondents claimed to have been victimized for raising their voice. Conflict was never resolved in seven cases. To reduce conflicts, respondents suggested that authorship should be decided before the study begins, order of authorship must be determined according to contribution, and a standard code of authorship should be followed strictly. Authorship conflicts arise among researchers mostly due to what they regard as unethical practice of their co‐authors, supervisors, and department heads in the absence of any formal authorship policy in the institutions. A standard code of authorship, sensitization of researchers to the problem through open discussions and advocacy, and formation of a grievance redress committee are suggested to minimize such conflicts. Although the sample size was small, some of the specific recommendations will be appropriate in many other cases.     

Scandix pecten-veneris L.的植物素、生物学潜力及酶抑制活性研究（英文）

目的:本研究旨在测定Scandix pecten-veneris L.的植物素和评价其生物学潜力。方法:测定S.pecten-veneris提取物中植物素的含量,包括生物碱、黄酮、多酚和单宁。使用2,2-二苯基-1-苦肼基(DPPH)测定抗氧化活性;同时通过铁还原/抗氧化能力(FRAP)测定还原能力;使用琼脂扩散测定法评价对七种细菌和四种真菌菌株的抗微生物活性。同时,对脲酶、磷酸二酯酶-Ⅰ和过氧化氢酶-Ⅱ进行酶抑制研究。结论:沙门氏菌显示出适度的抗自由基活性;羟基自由基的潜能降至初始值的20%左右。S.pectenveneris多种提取物的抗氧化活性与总酚含量呈线性相关。S.pecten-veneris叶对金黄色葡萄球菌表现出最高的抑制活性;对白色念珠菌表现出到最高的抗真菌活性。植物提取物对脲酶的活性最有效;对磷酸二酯酶-Ⅰ和碳酸酐酶-Ⅱ显示出中等活性。结果表明,S.pecten-veneris具有良好的药用潜力,可用于治疗一些特定的疾病。
