The collective consciousness of effective groups of researchers is characterized by shared understandings of their research object or territory. In this study, we adopted a phenomenographic approach to investigate information technology (IT) research, and its objects and territories, as they are constituted in the experience of IT researchers. Semi‐structured interviews were conducted with researchers representing different sub‐disciplines. Analysis revealed the variation in meaning associated with the idea of IT research; and the awareness structures through which participants experience variation in ways of seeing the object and territories of IT research. Eight ways of seeing IT research were found. The outcomes of our project appear to make visible the changes and developments that are an essential part of the character and experience of contemporary IT research. 相似文献
Whereas cognitive and linguistic factors for learning to read have been extensively studied, less is known about affective factors including children’s attitudes toward reading. Studies primarily from English-speaking and Western countries show gradual declines in reading attitudes in elementary school (McKenna et al., Reading Research Quarterly 30:626–639, 1995) and a positive association between reading attitudes and achievement (Petscher, Journal of Research in Reading 33:335–355, 2010). Children from Asian and African countries are underrepresented in this literature; whether these patterns can be generalized across cultures needs further investigation. This longitudinal study examined the reading attitudes of 84 children in Vietnam from grades 1 to 2 and their relations to reading performance, as measured by translated and adapted versions of the Elementary Reading Attitude Survey and Early Grade Reading Assessment, respectively. This sample from Vietnam showed a small decline in reading attitudes over time, particularly in attitudes toward academic reading. However, children on average reported feeling happy about reading in both grades. Correlations revealed different patterns of association between reading attitudes and performance based on the reading measure employed, grade level, and type of reading in question (academic versus recreational). In grade 2, reading attitudes explained unique variance in reading comprehension even after text fluency and mother’s education were considered. We present a margins plot to visualize the role of reading attitudes on reading comprehension. We discuss educational implications and future directions.
Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong. 相似文献
In this paper, a decision model is presented for the sales of software product to determine the profit and marketing policy under the influence of promotional efforts. The paper focuses on dependence of the optimal profit on the promotional efforts when there is diffusion effect of demand on the sales function. An elaborate optimization policy considering the dynamic nature of production cost function is proposed and numerical example is illustrated. The paper also studies the behavior of the future profit and its impact on profit maximization model by considering the constant price during the entire planning horizon. The experimental results greatly help us to identify the contributions of each selected parameter and its weight. Some conclusions, limitations of this study and future direction are also discussed. 相似文献

Quality accreditation in higher education exists in many countries, including Vietnam. As of May 2018, 80 higher education institutions in Vietnam have officially been evaluated and recognised using the national quality standards. This study examined the impact of institutional accreditation on the evaluated university. The qualitative research evaluates the impact of external quality assurance from the perspective of managers of the university. The self-assessment phase helped the university assemble evidence of activities carried out at the university and the status of being recognised was believed to increase its prestige. The process, on the other hand, was also believed to be burdensome, time and cost consuming, which led to no significant changes at the institution. Lack of institutional autonomy and competence of the review team were barriers to any attempts to improve quality of higher education in Vietnam. 相似文献
Intercultural interaction plays an important role in contributing to international students’ learning and wellbeing in the host country. While research on international students’ intercultural interactions reveals multifaceted aspects of personal and social factors, there is a tendency to consider language barrier and cultural differences as individual factors that constrain their interactions with the institutional community. Drawing on 105 interviews with international students in Australian vocational education and training and dual sector institutions, this paper examines international students’ intercultural interactions in host institutions and the factors that act as enablers or inhibitors for intercultural interactions. It highlights the social and structural conditions in creating symbolic capital of elitist Anglo-Australian culture and English language, and social differentiation. This paper offers insights into understanding the legitimacy of such elitism, in hope that future conceptualisation, research and practices of intercultural interactions may locate international students within their cultural diversity. 相似文献
