Despite multiple efforts and considerable funding, historically marginalized groups (e.g., racial minorities and women) continue not to enter or persist in the most lucrative of fields – technology. Understanding the potency of culturally responsive teaching (CRT), some technology-enrichment programs modified CRP principles to establish a culturally responsive computing (CRC) experience for disenfranchised groups. We draw from our respective praxes developing two such initiatives and reconceptualize CRC as a heuristic. In this theoretical article, we offer a more nuanced vision of CRC considering intersectionality, innovations, and technosocial activism. Implications for the newly defined tenets consider programmatic, theoretical, and methodological concerns. 相似文献

The contributions of volunteers in special libraries have not been well-documented or researched. However, anecdotal evidence shows that volunteers have played a key role in the formation of many special libraries and continue to lend their skills and knowledge to these libraries. This column explores examples from the literature and gives a brief case study on the various ways philatelic libraries use volunteers. The scope of the column includes traditional unpaid volunteers, remote volunteers, crowdsourcing, internships, job training programs, and other voluntary or nontraditional work. Volunteer labor is far from free in terms of cost to the organization, but can provide benefits beyond simply unpaid labor including subject expertise, special skills, and community building. Special libraries looking to begin or expand volunteer programs are advised to study the lessons learned from other types of libraries and organizations with successful volunteer programs. Successfully managing volunteers requires careful planning and coordination just as managing paid staff does. 相似文献

Librarianship has a long tradition of collaboration and cooperation between libraries, but the literature yields scant evidence of formal partnerships in practice in special libraries. This column explores the barriers to collaboration for special libraries, from organizational culture to legal constraints, as well as the potential benefits and how librarians can overcome the barriers to reap these benefits. Different types of collaboration, including among similar special libraries and between special libraries and other types of libraries and related organizations, as well as informal and formal cooperation, and short-term and long-term partnerships, are discussed. Collaboration and cooperation were part of the impetus to form professional associations. The column provides a brief history of professional library associations and their role in supporting library partnerships in the United States. The conclusion explores how the increasingly digital nature of information and library work affects collaborative library efforts and where the future of these efforts may lie, especially for special libraries. 相似文献

The primary aim was to examine the criterion and construct validity and test–retest reliability of the Lifesource XL-18 pedometer (A&D Medical, Toronto, ON, Canada) for measuring steps under controlled and free-living activities. The influence of body mass index, waist size and walking speed on the criterion validity of XL-18 was also explored. Forty adults (35–74 years) performed a 6-min walk test in the controlled condition, and the criterion validity of XL-18 was assessed by comparing it to steps counted manually. Thirty-five adults participated in the free-living condition and the construct validity of XL-18 was assessed by comparing it to Yamax SW-200 (YAMAX Health & Sports, Inc., San Antonio, TX, USA). During the controlled condition, XL-18 did not significantly differ from criterion (P > 0.05) and no systematic error was found using Bland–Altman analysis. The accuracy of XL-18 decreased with slower walking speed (P = 0.001). During the free-living condition, Bland–Altman analysis revealed that XL-18 overestimated daily steps by 327 ± 118 than Yamax (P = 0.004). However, the absolute percent error (APE) (6.5 ± 0.58%) was still within an acceptable range. XL-18 did not differ statistically between pant pockets. XL-18 is suitable for measuring steps in controlled and free-living conditions. However, caution may be required when interpreting the steps recorded under slower speeds and free-living conditions. 相似文献

The use of structural equation modeling (SEM) in communication research has become increasingly popular in recent years, with SEM being commonly used as the primary method of data analysis in studies published within the field’s journals. However, despite its widespread use, there are persistent misapplications of SEM in published empirical studies in the communication sciences. Of these types of misuse, the most troubling are those related to the exploitation of flexibilities in data collection and analysis. Given the number of decisions that must be made when analyzing and reporting structural equation models, decisions which often remain undisclosed, the potential for researchers to exploit flexibilities in SEM research is high. To assess the extent of this problem, as well as the more longstanding types of misuse (i.e., omission of information and disclosed “bad practice”) identified by prior studies, we undertake a methodical review of studies employing structural equation modeling within major journals in the field of communication between the years 2007 and 2011. Articles were coded on the characteristics of the sample, characteristics of the model tested, as well as for various potential problems that we defined a priori. The most serious issues are identified, and recommendations for future standards in SEM research are suggested. 相似文献

The candidate chooses projects for his or her ability to establish credentials as a performance technologist. The clearer the links between actions and improved performance for the client, the stronger the case each example makes. Candidates will need to show this linkage between contribution and outcome for each project used in preparing the submission package. 相似文献
