Over the past decade Identity Management has become a central theme in information technology, policy, and administration
in the public and private sectors. In these contexts the term ‘Identity Management’ is used primarily to refer to ways and
methods of dealing with registration and authorization issues regarding persons in organizational and service-oriented domains.
Especially due to the growing range of choices and options for, and the enhanced autonomy and rights of, employees, citizens,
and customers, there is a growing demand for systems that enable the regulation of rights, duties, responsibilities, entitlements
and access of innumerable people simultaneously. ‘Identity Management’ or ‘Identity Management Systems’ have become important
headings under which such systems are designed and implemented. But there is another meaning of the term ‘identity management’,
which is clearly related and which has gained currency. This second construal refers to the need to manage our moral identities
and our identity related information. This paper explores the relation between the management of our (moral) identities and
‘Identity Management’ as conceptualized in IT discourse. 相似文献
In Finnish VET, students’ work experience is explicitly defined as workplace learning, instead of the practice of already
learnt skills. Therefore, vocational students’ learning periods in the workplace are goal-oriented, guided and assessed. This
paper examines the characteristics of students’ workplace learning and compares them with the characteristics of employees’
workplace learning. The data were collected with an Internet questionnaire from final-year vocational students (N = 3106). In total, 1603 students (52 %) answered the questionnaire. The data were analysed using quantitative methods. The
results indicate that features typical of employees’ workplace learning can also be found in student learning as well. However,
VET-related workplace learning has a number of characteristics that have not been brought to light in research on employees’
workplace learning thus far. We suggest that in developing educational practices it would be useful to draw on some of the
features of workplace learning such as the use of collaboration and shared practices; conversely for workplace practices it
would be useful to draw on some of the features of educational practices. For example, by utilising the structures of students’
workplace learning system presented in this study, learning at work could be transformed towards more goal-directed, guided
and assessed activity. 相似文献
The research questions addressed in this study were: what types of epistemological beliefs do elementary students have; what
types of metacognition do elementary students have; and what are the relationships among students’ perceived characteristics
of constructivist learning environment, metacognition, and epistemological beliefs. A total of 626 students enrolled in sixth,
seventh, and eight grades of nine elementary public schools located in Ankara, Turkey constituted the participants of this
study. Constructivist learning environment survey (CLES), Junior metacognitive awareness inventory (Jr. MAI), and Schommer
epistemological belief questionnaire (EB) were administered to students. Factor Analysis of Jr. MAI revealed both knowledge
of cognition and regulation of cognition items were loaded into one factor. Confirmatory factor analysis of EB revealed a
four factor structure namely innate ability, quick learning, omniscient authority, and certain knowledge. Regression analyses
revealed that metacognition and omniscient authority were significant predictors of personal relevance dimension of CLES.
Metacognition was found as the only predictor of the student negotiation. Innate ability and metacognition significantly contributed
to uncertainty. This study revealed that the elementary students with different mastery levels hold different epistemological
beliefs and multi-faceted nature of elementary school students’ metacognition was seemed to be supported with this study.
It was found that metacognition contributed to model more than epistemological beliefs for all three dimensions of CLES. 相似文献
The purpose of this study is to examine the effect of creative drama-based instruction on seventh graders’ science achievements
in the ecology and matter cycles unit and their attitudes toward science. The study is an experimental study carried out in
one of the public elementary schools in Turkey during 2005–2006 schooling year. An ecological concept achievement test was
developed and administered to 45 students in two classes (as control and experimental group) of an elementary school before
and after the treatment. The experimental group received creative drama-based instruction and the control group received traditional
instruction. A guiding instruction material which contains six lesson plans in the subject was constructed for the teacher
to administer creative drama-based instruction. The topics of ecosystems and matter cycles were taught to the both of groups
for 3 weeks. A science attitude test was administered to both groups before and after the treatment. The results revealed
a statistically significant difference between the mean scores of the both groups with respect to achievement in the ecology
concepts and median of the attitudes toward science in favour of the experimental group after the treatment. 相似文献
The study reported here examined grade 2–4 children’s sensitivity to the consistency in the spelling of roots in related words.
We build on earlier research by attempting to quantify the extent that children’s spellings of both inflected and derived
forms accord with this principle. We contrasted children’s accuracy and consistency in spelling the root form (e.g., rock) with that of its spelling in related inflected and derived forms (e.g., rocks and rocky), as well as unrelated control forms (e.g., rocket). Across grades 2–4, children’s spellings accorded with the root consistency principle to the same extent for inflected and
derived forms. Nevertheless, it was not until grade 4 that spellings maximally reflected the principle. These results are
discussed in terms of how children’s spelling might come to reflect the root consistency principle that guides spelling in
English. 相似文献
The first objective of this study was to examine the presence of the impostor phenomenon (IP) among 740 students aged 10 to
12 years old. The second objective was twofold: (1) to examine the link between the impostor feelings and the propensity to
use social comparison and (2) to examine whether this feeling is related to the processes of identification with versus contrast
to others who are either doing better or worse than oneself. Results showed that, although generally of low intensity, the
impostor feelings are indeed present in late elementary school children. A positive link between the impostor feelings and
the propensity to use social comparison was also observed. It also appeared that, more than for others, children who feel
like impostors were likely to differentiate themselves from their more capable peers while identifying themselves with less
capable peers. The discussion focuses on the presence of the IP in late elementary children and on how the upward contrast
and the downward identification may contribute to its development and maintenance. 相似文献
Compared to isokinetic and isometric tests, isoinertial movements have been poorly used to assess single-joint performance. Two calculation procedures were developed to estimate mechanical performance during single-joint isoinertial movements performed on a customised isokinetic dynamometer. The results were also compared to appreciate the effects of measurement systems and calculation procedures. Five participants performed maximal knee extensions at four levels of resistance (30, 50, 70 and 90% of the one-repetition maximum, 1-RM). Joint angular velocity and torque were assessed from customised isokinetic dynamometer measures (method A) and from weight stack kinematic (method B). Bland–Altman plots and mean percent differences (Mdiff) were used to assess the level of agreement for mean and peak angular velocity and torque. A Passing–Bablok regression was performed to compare the angular velocity-angle and torque-angle relationships computed from the two analysis methods. The results showed a high level of agreement for all mechanical parameters (Mdiff < 6% for all parameters). No statistically significant differences were observed between methods A and B in terms of angular velocity-angle and torque-angle relationships except at 30% of 1-RM for the torque-angle relationship. Both methodologies provide comparable values of angular velocity and torque, offering alternative approaches to assess neuromuscular function from single-joint isoinertial movements. 相似文献
We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6–8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate motor performance score and physical activity was assessed by combined heart rate and movement sensor and cardiorespiratory fitness by maximal cycle ergometer test. In boys, BF% was inversely associated with reading fluency (β = ?0.262, P = 0.007) and reading comprehension (β = ?0.216, P = 0.025). Motor performance mediated these associations. Leptin was inversely related to reading fluency (β = ?0.272, P = 0.006) and reading comprehension (β = ?0.287, P = 0.003). The inverse association of leptin with reading fluency was mediated by motor performance. In girls, GGT was inversely associated with reading fluency independent of confounders (β = ?0.325, P = 0.007). The inverse association of BF% with academic achievement among boys was largely explained by motor performance. Leptin in boys and GGT in girls were inversely associated with academic achievement independent of confounding factors. 相似文献
Introduction: Social roles in physical education (PE) classes have been much studied, especially mentoring and coaching roles. The studies have shown that mentoring and coaching are beneficial not only for motor learning, but also for methodological and social learning. To our knowledge, the role of the student referee in PE lessons has never been specifically studied. Yet refereeing is essential in many sports, including team sports, and provides an experience of responsibility that many teachers want to offer their students. Encouraging students to take on this role can nevertheless be difficult.
Objective: The objective of the present study was to gain access to students’ lived experiences as referees in order to determine their strategies for being effective. We particularly wanted to determine which concerns organized their activity so that we could identify a refereeing typology that would be useful for PE teaching. Our study is original in that we did not rely exclusively on experiential data to understand student refereeing activity. We also collected data on the students’ motivation in order to better understand their experiences. For this purpose, the study was conducted within the methodological framework of course-of-action theory and self-determination theory.
Method: Seventy-four students from three classes in the third year of middle school (about 13 years old) participated in the study. Among them, four (two girls and two boys and not experts in the sports in which they were going to referee) had volunteered to be filmed and to participate in self-confrontation interviews. The other students completed two questionnaires to provide information on their motivation for refereeing. The situations studied were basketball and handball matches held at the end of the lessons.
Two categories of data were collected: qualitative and quantitative. The qualitative data were based on audiovisual recordings of the students as they refereed matches and verbalization data from self-confrontation interviews; these data were used to document the students’ courses of experience during the activity period under study. The quantitative data were collected using two questionnaires, one to assess the determinants of motivation and the other to assess self-determined motivation.
Results and discussion: The qualitative analysis highlighted three typical student involvements: fulfilling the role of referee, getting help, and occasionally dropping out of the role. The quantitative analysis revealed that the students in the social role of referee mainly expressed amotivation, external regulation, and intrinsic motivation toward knowledge and accomplishment.
The results are discussed around two major points: (1) the students’ strategies of alternation from which their refereeing activity emerged and (2) proposals for PE teacher interventions. 相似文献
