Culturally responsive computing: a theory revisited

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.     

Lifesource XL-18 pedometer for measuring steps under controlled and free-living conditions

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.     

Undisclosed Flexibility in Computing and Reporting Structural Equation Models in Communication Science

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.     

整形 已成现代生活的一部分?!

只要提起"动手术",很多人都会毛骨悚然。然而却有越来越多人为了"变美"而甘愿挨刀子,在整形手术从拒绝到争议再到逐渐被接受的这个过程中,我们看到了技术的进步,和人们更加开放包容的态度。但这是否就意味着我们可以无条件地接受整形?做整形手术的人数在不断增加,但没有人会对此扬起眉毛啧啧称奇。去年英国"治疗"("治疗"一词似乎不太合适,但不管了)了50,122名整形人士,而其中90%是女性,同样也     

Preparing a CPT Submission Package

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.     

Racial and Gender Identity Among Black Adolescent Males: An Intersectionality Perspective

A considerable amount of social identity research has focused on race and racial identity, while gender identity, particularly among Black adolescents, remains underexamined. The current study used survey data from 183 Black adolescent males (13–16 years old) to investigate the development and relation between racial and gender identity centrality and private regard, and how these identities impact adjustment over time. It was found that dimensions of racial and gender identity were strongly correlated. Levels of racial centrality increased over time while gender centrality, and racial and gender private regard declined. In addition, racial and gender identity uniquely contributed to higher levels of psychological well‐being and academic adjustment. These findings are discussed within the context of existing identity theories and intersectionality theory.     

Parental Cultural Socialization of Mexican‐American Adolescents’ Family Obligation Values and Behaviors

The current study examined how parents’ cultural socialization efforts contribute to adolescents’ family obligation values and behaviors and how these processes may depend upon the relational climate at home. Utilizing survey and daily diary methodologies, 428 Mexican‐American adolescents (50% males; M_age = 15 years) and their parents (83% mothers; M_age = 42 years) participated in the study. Adolescents reported on their family obligation values and engagement in family assistance tasks across 14 days. Parents reported on their cultural socialization practices. Results indicated that parental cultural socialization was associated with adolescents’ family obligation values and behaviors when parent–child relationships were low in conflict and high in support. Findings suggest that the transmission of cultural values and practices is best facilitated through positive parent–child relationships.
