This study seeks to shed light on the informal process of knowledge production in criminology and criminal justice by examining acknowledgements in journal publications. Studying the structure of research collaboration among scholars may enhance our understanding of the discipline’s organization. We test hypotheses derived from prior research by analyzing acknowledgements in 786 articles from five journals in criminology and criminal justice over the last five years. As anticipated by the “invisible college” hypothesis, criminology and criminal justice scholarship contains a small group of individuals who receive a disproportionate share of acknowledgements. Additionally, we find that higher ranked and more productive scholars are awarded more acknowledgements than their lower ranked and less productive counterparts. Integrating acknowledgements as an unofficial assessment tool may improve the collective endeavor of contemporary science in our field. Overall, the influence of the “invisible colleagues,” measured by acknowledgements, demonstrates the value of collaboration in the process of knowledge production. 相似文献

在伊犁州三地区九年义务教育阶段,教师对学生的校园暴力的现象十分普遍.随机抽样调查认为:受暴力行为伤害的学生比例,农村大于城市、汉族大于少数民族、差生大于优生、男生大于女生,其中受隐性暴力行为伤害的学生比例远大于显性暴力,而且初中大于小学,初三尤为严重;受显性暴力行为伤害的学生比例小学大于初中,小学高段比例更大.教师对学生施暴的主要原因是工作方法欠缺,法制观念淡薄,尤其是升学竞争压力大和学生被教师施暴后的沉默态度.要想制止校园暴力行为,必须改革我国现行的教育考试制度,树立对教师、学生新的评价观,全面提高教师、学生的素质,使每个学生在儿童、青少年时期健康而全面的发展,真正落实素质教育. 相似文献

In this study, we explore how career orientations of Russian high schoolers are related to the quality of their academic capital. We introduce and validate the concept of the academic capital of high school students. We describe why we chose Schein’s Career Orientations Inventory as a screening instrument, which allows us to determine whether the individual is aware of their vector of future career advancement, and we propose how the instrument can be modified to be used among the cohort of high school students that form the subject of our study. During the course of the study, we tested three hypotheses of the interrelationship between the academic capital of high school students and their career orientations. 相似文献

In this article we will present findings from a national survey questioning the actual impact of the new governance structures
at German universities on academic teaching. To begin with, we give a theoretical underpinning to the economization of higher
education institutions (HEIs) according to Principal-Agent Theory. This allows for the development of hypotheses about the
influence of new selective incentives (merit pay, performance-related budgeting, Management by Objectives, teaching awards)
on the professors’ academic teaching behavior. Instructed by critical considerations on Principal-Agent Theory we extended
the axiomatics of this economic theory by incorporating concepts like work task motivation and academic socialization for
a supposedly more comprehensive explanation. Data from a nationwide German survey allows us then to test our theory-driven
assumptions. Our target population was the entire collectivity of all professors at German universities from which we could
draft a sample 8,000 individuals. An estimation of four different OLS-regression models shows that the hypotheses derived
from Principal-Agent Theory must be rejected whereas the hypotheses based on motivational aspects and socialization processes
can be confirmed. Based on our analysis we can conclude that for the status quo of implementation there are no direct influences
of new selective incentives on the actual teaching performance whereas we have strong indications for altered mechanisms of
enculturation in the field of universities. New Public Management (NPM) seems to produce a new breed of professors whose preferences
and practice are conditioned by the imperatives evoked by this new managerialism. 相似文献

This study was designed to address two purposes. First, we wanted to test working hypotheses derived from previous studies
about the transformation of individual and collective knowledge in elementary classrooms. Second, we attempted to understand
the degree to which “ownership” was an appropriate concept to understand the process of learning in science classrooms. Over
a four-month period, we collected extensive data in a Grade 6/7 classroom studying simple machines. As in our previous studies
we found that (a) conceptual and material resources were readily shared among students, and (b) tool-related practices were
appropriated as newcomers participated with more competent others (peers and teachers) in the pursuit of student-framed goals.
We also found that for discursive change (“learning”) at the classroom level to occur, it appeared more important whether
a new language game was closely related to students' previous language games than who actually proposed the new language game
(teacher or student). Implications are drawn for the design of science curricula and classroom activities.
Both pedagogy and design are still tightly bound by rationalist, symbol-manipulating, problem-solving assumptions that hold
knowledge to be a property of individuals. Pedagogy still concentrates on the individual and individual performance, even
though most work is ultimately collaborative and highly social. (Brown & Duguid, 1992, p. 171) 相似文献

Avi Mintz (2008) has recently argued that Anglo-American educators have a tendency to alleviate student suffering in the classroom. According to Mintz, this tendency can be detrimental because certain kinds of suffering actually enhance student learning. While Mintz compellingly describes the effects of educator's desires to alleviate suffering in students, he does not examine one of the roots of the desire: the feeling of compassion or pity (used as synonyms here). Compassion leads many teachers to unreflectively alleviate student struggles. While there are certainly times when compassion is necessary to help students learn, there are other times when it must be overcome. Compassion in the classroom is a two-edged sword that must be carefully employed; and yet it is often assumed that it is an unequivocal good that ought to trump all other impulses. In this article I hope to raise awareness concerning the promises and pitfalls of compassion in education by examining the theories of two historical figures who famously emphasised compassion in their philosophical writings: Jean-Jacques Rousseau and Friedrich Nietzsche. Rousseau and Nietzsche argue that compassion is a powerful educational force but that it must be properly employed. For Rousseau and Nietzsche, compassion is necessary to develop self-mastery in human beings—the ultimate goal of education—but it is a compassion that must hurt in order to help. My hope is that Rousseau's and Nietzsche's ideas on compassion will encourage thoughtful reflection on the uses and abuses of compassion in education. 相似文献

贺享雍的长篇小说《土地神》就是从农民身处的精神境况出发,希望通过底层农民对生存的困境进行反抗、对自身的卑微进行抗争、对现实的强权进行反讽,在伤害与被伤害、侮辱与被侮辱、欺骗与被欺骗的怪圈中,展示历史、现实强权与个体农民之间的巨大张力,揭示出农民生存的伤痛和农村现代性的艰难。在这部小说中,我们既能看到历史强权的抽象,又能看到乡村现实的还原。 相似文献

INTRODUCTION The development of network technology led to the appearance of many high-speed networks with bandwidth larger than 1 Gbps, or even 10 Gbps. Through high-speed networks, applications like sci- entific collaboration, telemedicine, and real-time environment monitoring can transfer high-bandwidth real time data, images, and video captured from re- mote sensors such as satellite, radars, and echocar- diography. What is more, data intensive grid applica- tion (Foster et al., 2001)… 相似文献

我们知觉到的都是单个的个体,然而语言中真正具有解释意义的是那些表达共相的词语,但我们既能够认识共相也能够认识殊相。这个事实揭示了我们语言所具有的意向性,这种意向性使得我们能够超越共相而指向个体,超越语言而抵达世界。而这一切的基础则是我们意识的意向性,正是意向性在我们这个一切皆流的世界中将世界个体化,进而通过语言将世界转化成一个相对静止的、具有固定意义的世界。对于这个过程而言,我们自身既是这个过程的发起者,也是这个过程的产物。 相似文献

Several studies have focused on the role of students’ conceptions of intellectual ability, the learning process and the self-efficacy. However, these three parameters have not been integrated and analysed within the same model. Against this background, the objective of our research is to identify the links that develop between these three constructs. To this end, we have put forward two hypotheses: 1. The conception that intelligence is constructed directly and positively affects the conception that learning is a constructive process. This has a positive impact on perceived self-efficacy. 2. The conception that intelligence is a fixed trait directly and positively affects the conception that learning is a reproductive process and leads to lower perceptions of self-efficacy. To test these hypotheses, we conducted research using a questionnaire distributed among 1112 students in their last year of primary school. The questionnaires were subject to statistical analysis using structural equation modelling. The results confirm our hypotheses and thus show the relevance of our model. 相似文献
