Can Detroiters Dream Again? The Imagined Dialectics of Urban Decline in Anthony Bourdain’s Parts Unknown—Detroit     

Eun Young Lee  Chad Nelson 《Communication Studies》2018,69(4):421-438

Examining the Detroit episode of Anthony Bourdain’s CNN show, Parts Unknown, this study illuminates how the collective memory of the American dream is ironically projected onto Detroit, the metonymic city of America past. In order to identify the nostalgia of the American dream narrated in the show, we apply the dialectical approach to intercultural communication suggested by Martin and Nakayama and propose the imagined dialectics. Throughout our analyses, we contend that the imagined dialectic narrated in the Parts Unknown episode nostalgically frames Detroit’s past, which inevitably fetishizes its present. We ultimately argue that the nostalgia of the American dream epitomizes the lack of an intercultural and interregional understanding within the US and prevents us from democratic discussion for the betterment of the urban lives.  相似文献

Content Validation of the Community College Student Success Program Inventory     

Deryl K. Hatch  Naomi Mardock-Uman  Matthew J. Nelson 《Community College Journal of Research & Practice》2018,42(6):439-444

This study reports on the content validation of the Community College Student Success Program Inventory (CCSSPI), a structured interview protocol for program personnel, designed to serve as a tool for researchers and practitioners alike to account for critical features of various types of student success programs in detailed and comparable ways across multiple sites. In all, 20 subject matter experts (SMEs) rated the relevancy and clarity of each item to ascertain essential program features. Content validity index (CVI) and scale-level index scores (S-CVI) were calculated. Results showed high to moderately high validity for items related to course goals, logistics, skills-focused curricular items, and academic and student services. Other contingent facets—collaborative and contextualized learning, co-curricular and community activities, ancillary instruction, and instructor role—were rated as less valid, depending on program goals. The instrument is recommended for use in multisite qualitative or mixed-methods research and institutional improvement.  相似文献

Audience Currencies in the Age of Big Data     

Jacob L. Nelson  James G. Webster 《媒体管理杂志》2016,18(1):9-24

ABSTRACT

Audience ratings data have long occupied the attention of marketers and media managers. These are the “currencies” that support the operation of commercial media. Today, metrics can be derived from many large datasets, raising the possibility that new kinds of currencies might emerge. We argue that data on exposure are the most likely to support currencies, and that these might well go beyond traditional measures of audience size and composition. We explore the relationship between the most plausible contenders for audience currencies: size and engagement as measured by time spent. Contrary to the “Law of Double Jeopardy,” we find these metrics to be uncorrelated in an online environment, suggesting that each might have a role to play as a currency. We conclude with a discussion of how the political economy of audience measurement is likely to affect audience currencies in the age of big data.  相似文献   

Carbohydrate gel ingestion during running in the heat on markers of gastrointestinal distress

The purpose of this study is to measure the effects of carbohydrate ingestion during exercise in the heat by measuring markers of gastrointestinal damage and inflammation. Methods: Active subjects (n?=?7) completed two 60-min running trials in a heated environment (70% VO₂max, 30°C). At minute 20 of exercise, subjects consumed a carbohydrate gel (Cho) (27?g), or a non-carbohydrate placebo (nCho). Plasma endotoxin, I-FABP, TNF-α, IL-6, IL-1β, IL-10, and MCP-1 were measured pre-exercise, 20-min post-exercise, and again 2-h, and 4-h post-exercise. Results: Endotoxin increased 20-min post-exercise compared to pre in the Cho trial only (p?=?.03). I-FABP levels increased 20-min post-exercise in the Cho trial only compared to pre-exercise (p?=?.003). I-FABP levels were also increased in Cho trial 20-min post-exercise when compared to same time point in the nCho trial (p?=?.032). TNF-α increased 20-min post-exercise in the Cho trial only compared to pre (p?=?.03). Plasma IL-6 concentration increased 20-min post-exercise when compared to pre in both the Cho (p?=?.002) and nCho (p?=?.009), but remained elevated at the 2-h time point in the nCho trial (p?=?.03). I-FABP and several plasma cytokines (TNF-α, MCP-1, Il-6) returned to baseline sooner in the Cho trial. Conclusions: Ingestion of carbohydrate gel during exercise in the heat enhances markers of gastrointestinal wall damage.  相似文献   

Managing cognitive load in educational multi-user virtual environments: reflection on design practice   总被引：1，自引：0，他引：1  

Brian C. Nelson  Benjamin E. Erlandson 《Educational technology research and development : ETR & D》2008,56(5-6):619-641

In this paper, we explore how the application of multimedia design principles may inform the development of educational multi-user virtual environments (MUVEs). We look at design principles that have been shown to help learners manage cognitive load within multimedia environments and conduct a conjectural analysis of the extent to which such principles can help manage cognitive load in the highly immersive “beyond multimedia” environments that 3-D educational MUVEs represent. We frame our discussion as a design practice analysis of the River City MUVE, a science inquiry environment that has middle school students collaborating to develop and test hypotheses regarding illnesses sweeping a virtual town. We analyze the current River City interface design using a framework describing cognitive overload scenarios and associated approaches to manage cognitive load. We also discuss the potential difficulties that may be seen as multimedia principles are applied to 3-D MUVEs. Our discussion describes a blueprint for research implementations that we are undertaking to systematically investigate the effect of an educational MUVE interface design based on multimedia principles—implementations that we hope will provide an action framework for other MUVE researchers to use in their own studies.  相似文献   

Factors Related to the Extent of Mortality among Home Economics Students in Certain Colleges of Minnesota,Wisconsin and Iowa during 1943-50     

Helen Y. Nelson 《Journal of Experimental Education》2013,81(1):59-63

Because of low verbal skills exhibited by deaf subjects and because of earlier research results linking verbal behavior to aesthetic behavior, this preliminary investigation sought to lay some groundwork for an empirical study of the relationship between these two ordering systems. This study states the postulates upon which our working paradigm is based and presents the results of a correlational analysis of syntactic and aesthetic preference scores of ninety-two deaf high school students (both profoundly deaf and legally deaf). The results appear to corroborate earlier findings linking syntactic and aesthetic behavior. The study suggests the direction for an experimental study which is now in operation under a university grant.  相似文献
