This study aimed to investigate the scholarly information-seeking behavior of academic engineers and technologists working at the University of the Punjab. The purpose of the study was to investigate the various information sources being used by academic engineers and technologists for their scholarly tasks, with a focus on use patterns of e-journals. A quantitative study employing “survey” method was conducted to achieve the research objectives. A self-administered questionnaire was distributed to all regular and contractual academic engineers and technologists working at the university and a response rate of 61% was achieved. The study findings showed that the respondents' most-used information sources were e-journals, e-books, discussion with colleagues, and electronic research reports. They accessed e-journal articles through general search engines, Google Scholar, and open access e-journal websites. Majority of the respondents used e-journals for keeping themselves up-to-date and supervising researchers. While previous studies have investigated academic and practitioner engineers' information-seeking habits, this study is valuable as it investigated academic engineers' and technologists' scholarly information-seeking behavior in relation to their e-journals use patterns. 相似文献

This study examines the experiences of transgender college students in coping with stress in comparison to their cisgender peers. Undergraduate and graduate students from 73 colleges, totaling 26,292 participants, of which 47 identified as transgender completed an online survey. Transgender students reported greater exposure to trauma and higher rates of suicidal experiences, as well as different precipitants to reported stressful periods and sources of support than their cisgender peers. Implications for individual and group counseling as well as outreach and prevention to better support transgender students are explored. 相似文献

This study aimed at investigating the relationship between intellectual, social, personal and personality variables of academically gifted secondary school students. A total of 297 tenth grade boys and girls were identified on the basis of three main criteria: 1. Academic achievement with special emphasis on Arabic language, science and math scores; 2. Behavioural traits; 3. General mental ability and general adjustment. Data related to socioeconomic status and personal characteristics were also collected. Results of the analysis of variance showed that there were significant differences between gifted and nongifted groups in general mental ability, achievement, general adjustment, behavioural traits, personal and social variables, in favour of the former. 相似文献

This article explores the raced representations of the “Muslim Other” and how these representations engaged the lived realities and found footing in how Muslim youth understood their identities. Utilizing qualitative life history interviews with 24 Muslim undergraduates, I examine student talk addressing the construction of the Muslim in public discourse. 相似文献

微生物给人类带来了有利又有害的一面。这些有利的影响一般源于人们与微生物之间的共生关系。但是人类一些疾病的产生使得看似友好的微生物成为条件致病菌,使人们感染上微生物相关的疾病。人们致力于研究多种抗菌剂用于治疗和抑制病原微生物的感染,但是微生物耐药性的出现使得人们的研究进程受阻。尽管已有大量关于药物开发的研究缓解了这个难题,但微生物对这些药物的耐受性以及持续的微生物进化变异,使研究人员把重点放在筛选各种植物膳食类化合物上以用于抗菌。亚麻酸及其衍生物(二十碳五烯酸和二十二碳六烯酸)是已被广泛研究的omega-3脂肪酸,在人类的健康方面扮演着重要的角色,对大脑、眼睛、心血管系统和人的正常成长都有重要作用。然而,作为抗菌剂的使用并没有受到人们广泛的重视,可能是由于人们缺乏对其抗菌机制、药理毒性以及给药方式的了解。因此,本文综述了omega-3脂肪酸作为替代药物在治疗和预防微生物相关疾病中的作用。 相似文献

This paper proposes an optimization scheme for optimal configuration and energy management of the micro-grid (MG), using the Cuckoo search optimization algorithm (CSOA). The selected MG supplies a load profile located between 30.119 latitude and 31.605 longitude. The energy produced by the MG generation sources, according to meteorological data of the proposed location, is calculated using MATLAB. The objective/fitness function is modeled and designed for minimizing the total investment cost (TIC) including capital, investment, operation and maintenance costs. A novel weighted goal attainment function (WGAF) has been proposed to reduce CO2 emissions and their associated costs. Moreover, WGAF also applies higher taxes on the amount of emissions that exceed governmental approved limits. To investigate the effects of WGAF on the TIC ($/year), annual cost of energy ($/kWh), and CO2 emissions, various weighted coefficients are analyzed. The simulation results have shown that the designed optimization scheme can robustly and efficiently produce the optimal MG configuration that is both eco-friendly and generates economic benefits. 相似文献

Surveillance practices are becoming increasingly insidious, finding their way into nearly every aspect of public and private life in the United States. Surveillance by state policing agencies have particularly targeted and criminalized communities of color. Such practices are not simply a new context, but are part of a broader carceral state, structuring all aspects of social life. Drawing upon a year and a half of ethnographic fieldwork with Muslim youth in New York City, I attempt to engage in a practice of “uncomfortable reflexivity” to ask how living within a carceral state that actively surveils Muslim communities affected the ways in which Muslim youth engaged me, a social researcher, and the tools I used to collect data. This research recognizes that youth are not simply there for researchers to take knowledge from, even if “insider” researchers have meaningful relationships with them. Rather, this research depicts that young people are carefully engaged in thoughtful and creative ways to ensure their own safety is protected. Ultimately, this study points to the necessity of research that is both self-reflective in its design as well as in its ability to make claims about youth experiences. 相似文献

Two reef margin species of tropical sea urchins, Echinometra sp. C (Ec) and Echinometra oblonga (Eo), occur sympatrically on Okinawa intertidal reefs in southern Japan. Hybridization between these species was examined through a series of cross-fertilization experiments. At limited sperm concentrations, where conspecific crosses reached near 100% fertilization, both heterospecific crosses showed high fertilization rates (81%–85%). The compatibility of the gametes demonstrated that if gamete recognition molecules are involved in fertilization of these species, they are not strongly species-specific. We found that conspecific crosses reached peak fertilization levels much faster than did heterospecific crosses, indicating the presence of a prezygotic barrier to hybridization in the gametes. Larval survival, metamorphosis, and juvenile and adult survival of hybrid groups were nearly identical to those of their parent species. Hybrids from crosses in both directions developed normally through larval stages to sexually mature adults, indicating that neither gametic incompatibility nor hybrid inviability appeared to maintain reproductive isolation between these species. In adults, Ec×Ec crosses gave the highest live weight, followed by Eo (ova)×Ec (sperm), Ec (ova)×Eo (sperm), and Eo×Eo. Other growth performance measures (viz., test size, Aristotle’s lantern length, and gonad index) of hybrid groups and their parental siblings showed the same trends. The phenotypic color patterns of the hybrids were closer to the maternal coloration, whereas spine length, tube-foot and gonad spicule characteristics, pedicellaria valve length, and gamete sizes showed intermediate features. Adult F1 hybrids were completely fertile and displayed high fertilization success in F1 backcrosses, eliminating the likelihood that hybrid sterility is a postzygotic mechanism of reproductive isolation. Conversely, intensive surveys failed to find hybrid individuals in the field, suggesting the lack or rarity of natural hybridization. This strongly suggests that reproductive isolation is achieved by prezygotic isolating mechanism(s). Of these mechanisms, habitat segregation, gamete competition, differences in spawning times, gametic incompatibility or other genetic and non-genetic factors appear to be important in maintaining the integrity of these species. 相似文献
