This paper examines one particular problem of values in cloud computing: how individuals can take advantage of the cloud to store data without compromising their privacy and autonomy. Through the creation of Lockbox, an encrypted cloud storage application, we explore how designers can use reflection in designing for human values to maintain both privacy and usability in the cloud. 相似文献

Research has established that adolescents both befriend peers based on their academic achievement and adjust their own achievement to that of their friends’ over time. However, these processes may be different for ethnic minority students, because some of them may adhere to an oppositional culture that rejects striving for academic success. We examine respective differences between self-identified ethnic minority and majority students using longitudinal social network analysis (stochastic actor-oriented models) in a sample of 1175 students (aged 13) from 12 grade-level networks in Germany secondary schools. Among the students, we find that academically successful students in particular prefer friends with high grades, but that students with poor grades exert more social influence on their friends to adjust their performance. Moreover, while minority students are indeed less inclined to select friends with higher grades, both ethnic majority and minority youth prefer friends with similar academic achievement and are similarly influenced by their friends’ achievement. However, social influence is stronger from same-ethnic than from inter-ethnic friends. In sum, there is mixed evidence for an oppositional culture among ethnic minority students in our sample. 相似文献

Objectives
What impact does the strengthening of child rights have on the experience and circumstances of children? CRC General Comment 13 emphasizes that defining measurable targets for improvements in child protection is a key element of efforts to strengthen child rights and well-being across the world. This paper describes an attempt to identify key domains relevant to such mapping of child protection indicators, and the feasibility of collecting data—from existing data sources or otherwise—to complete a “National Child Protection Index Report” summarizing achievements and concerns at a national level.Methods
A process of inter-agency consultation was facilitated by the CPC Learning Network to establish a template for the Index Report. The template was modeled on that used for the “Countdown to 2015” maternal, neonatal and child health initiative, aiming to capture indices not only of key protection risks but also implementation and coverage of key protection measures. The work drew on indicator development and policy initiatives by a number of international child protection agencies. The template developed was used as a basis to pilot national data collection in Indonesia and, at a sub-national level, in northern Uganda.Findings
The template provides a concise summary of protection issues of relevance to a broad range of constituencies, global and national. However, in the pilot settings, existing routine data collection was inadequate to effectively populate a large proportion of indicators. Mechanisms of collating findings from discrete assessments—another potential source of data for completion of the index report—were also generally underdeveloped.Practice implications
In settings where state infrastructure allows the collection and analysis of routine data in such domains as health and economic activity, such efforts should be extended to the child protection sector. Discrete assessments by governmental or non-governmental agencies also provide significant potential for more effective sharing and collation of information. National Child Protection sub-clusters or equivalent structures can play an important role in facilitating both of these processes. 相似文献6.

A partnership was initiated between educators of the College of Medicine and the McGoogan Library at the University of Nebraska Medical Center to establish a new educational component for incoming medical students. The objective was to encourage the development of the students' independent information seeking skills. A three-day seminar was introduced in which the process of seeking information was emphasized rather than the final product. Cooperative development of the seminar resulted in a fresh approach to educating medical students at the College of Medicine and the emergence of an ongoing instructional link between the library faculty and educators in the College of Medicine. 相似文献

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed. 相似文献

Children identified as normal or as specifically language impaired (SLI) were given speech, language, and intelligence testing
on a longitudinal basis. Fourteen normal and 29 SLI children between the ages of 4 1/2 and 8 years were tested at Time 1.
They were retested three to four years later when they were 8 to 12 years old. The results indicated that both the normal
and the SLI children continued to develop skills in receptive and expressive language and speech articulation across the 3-
to 4-year period intervening between evaluations. Overall, however, the SLI children appeared to develop language skills at
a slower than normal rate and 80% of them remained language impaired at Time 2. In addition, the majority of the SLI children
manifested reading impairment at Time 2, while none of the normal children did so. The implications for the educational management
of SLI children are discussed.
