Pleurotus sajor-caju (Fr.) Singer was cultivated on selected agro wastes viz. cotton stalks, groundnut haulms, soybean straw, pigeon pea stalks and leaves and wheat straw, alone or in combinations. Cotton stalks, pigeon pea stalks and wheat straw alone or in combination were found to be more suitable than groundnut haulms and soybean straw for the cultivation. Organic supplements such as groundnut oilseed cake, gram powder and rice bran not only affected growth parameters but also increased yields. Thus bioconversion of lignocellulosic biomass by P. sajor-caju offers a promising way to convert low quality biomass into an improved human food. 相似文献

Research has indicated benefits to individuals and society of holding a multicultural versus colorblind ideology. This cross-sectional study tested the association of endorsement of multiculturalism with the individual difference constructs of identity exploration, identity confusion, and openness. Participants were 188 college students who completed a survey. Multiple regression analyses indicated that identity exploration, identity confusion, and openness independently predicted multicultural ideology. Additionally, identity exploration and identity confusion interacted such that identity exploration was associated with multiculturalism when identity confusion was low, but not when identity confusion was high. These findings indicate that general individual differences in personality and identity are predictive of cultural-related attitudes, and have implications for the design of interventions aimed at increasing multiculturalism. 相似文献

Abstract This essay recognizes that representations of the ‘Muslim woman’ as the Othered ‘object’ of the ‘Western’ gaze and the domesticated ‘object’ which the Islamic apologists strive hard to defend, are both constructions and false antitheses of each other. It seeks not the ‘truth’ regarding the Muslim women in the world of social reality but to examine how various representations of the women are constructed and to what effects and consequences these representations are mobilized. The essay proceeds in three stages. The first stage shows how the patriarchy mobilizes the Qur’an and the Hadith in order to construct the woman as the negative, the inessential and the abnormal of the man so as to exert complete subordination over her. However, the very act of attempting to mute the woman in Islam is the most strident proof that she is engaged in resistance against patriarchal control and the degree of resistance must be judged by the degree of patriarchal control. The second stage demonstrates how patriarchy operates in colonial and neo‐imperial landscape: it legitimizes the appropriation of Muslim woman ‘possessed’ by the Other (as exemplified by the orientalist seduction fantasy in William Dalrymple’s The White Mughals), but, haunted by the fear of rape and anxieties regarding the sexuality of the White woman possessed by the Self, it attempts to maintain strict control over her (as in the cases of Miss Wheeler in the ‘Mutiny’ of 1857 and Private Jessica Lynch in the Iraq War). This struggle over the feminine body is perfectly in line with Islam’s hyper‐anxiousness to hide the female body and rigorously ensure monopolic possession over her. The third stage shows how Taslima Nasreen, a late‐20th century feminist from Bangladesh, speaks the unspoken and thereby attempts to subvert the normative representation of the muted women in her autobiographical novella, entitled āmār Meyebelā. In thus examining the representations of the Muslim women, this essay seeks an alternative ‘third space of enunciation’ and takes a distinct political stand located outside of the axis of the dichotomy of the ‘Western’ gaze and the construction of the Islamic theologians. 相似文献

The correlation between antioxidant capacity and oxidative damage during aging has been reported in several tissues in different
species. Glutathione-S-transferases (GST) can metabolise endogenous and exogenous toxins and carcinogens by catalysing the
conjugation of diverse electrophiles with reduced glutathione (GSH). We observe a significant (P < 0.001) increase in plasma GST activity as a function of human age (r = 0.5675). A significant (P < 0.001) positive correlation (r = 0.8979) is observed between GST activity and total plasma antioxidant potential measured
as ferric reducing ability of the plasma (FRAP). GST activity and red cell intracellular GSH also show a significant positive
correlation (r = 0.7014). We hypothesize that the increased activity of plasma GST is a manifestation of increased generation
of ROS and a concomitant decrease in the level of plasma antioxidant capacity during aging. 相似文献

Several studies have found that older women report lower self-rated health than men. However, it is not clear why older women are more likely to report poor self-rated health than older men. Data for this study came from a national cross-sectional survey, Mental Health and Quality of Life of Older Malaysians (MHQoLOM). Included in the survey were 2980 respondents consisting of Malaysians aged 60 years and over, with both men (n = 1428) and women (n = 1552) represented. Results of t-tests showed older men expressed significantly higher levels of self-rated health and self-esteem than women (p < .01). Separate multivariate regression by gender revealed that age, life-threatening problems, and self-esteem were highly significant predictors of self-rated health among older men and women and explained 18.4% of variance in self-rated health for men and 18.2% for women. In the last step we examined the main effects of gender on self-rated health using General Linear Models (GLM) Univariate by adjusting for age, life-threatening problems, and self-esteem. Results showed an insignificant difference in self-rated health between older men and women (F (1,2715) = 2.26, P = 0.13) only after adjusting for self-esteem. It can be concluded that self-esteem affects responses to self-rated health of older men and women. 相似文献

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK. 相似文献

Teachers always played a significant role in the intellectual and moral development of students by using various techniques, assessments, and methods to improve student achievement in school＇s subjects. This study therefore focuses on the effect of teacher factors, such as assessment interval, communication language, the distance of residence, and the teacher＇s personal characteristics （gender, age, academic and professional qualification, designation, experience, and in-service training） on the 9th grade students＇ achievement in three subjects （English, Chemistry, and Mathematics at secondary level）. The population of the study is comprised of all ＂public sector＂ secondary schools, male and female teachers, and boy and girl students. A total number of 16 secondary schools （eight for boys and eight for girls）, 114 secondary school teachers （66 males and 48 females）, and 2,404 students （1,400 boys and 1,004 girls） were selected through purposive sampling techniques. Multiple statistical procedures, Spearman and Pearson correlation, mean, and standard deviation were employed to obtain stronger validity to the study. The results of the study identify weak and negative weak relationship between most of the teacher factors and student achievement in three subjects but the relationship between students＇ background and learning achievement in all three subjects were found positively correlated. 相似文献

This paper deals with the leader-following consensus problem of multi-agent systems with the consideration that each agent can only transmit its position state to the neighbors at irregular discrete sampling times. In the proposed algorithm, a continuous-discrete time observer is designed for the continuous estimation of both position and velocity from the discrete position information of the neighbors. These estimated states are then used for designing a continuous control law which solves the leader-following consensus problem. Moreover, the dynamics of the leader is not fixed and can be controlled through an external input. The stability analysis has been carried out by employing the Lyapunov approach which provides sufficient conditions to tune the parameters according to the maximum allowable sampling period. The developed algorithm has been simulated and then tested on an actual multi-robot system consisting of three differential drive wheeled robots. Both simulation and hardware results validate the effectiveness of the control algorithm. 相似文献
