Dialogic Cultural Relationships of Expertise, Knowledge, (Inter)dependence and Power Within the Acculturating Family: Exploring the Technolinguistic Brokering Experiences of Adolescents and Their Immigrant Non-English Speaking Mothers

Description

This dissertation explores the technolinguistic brokering experience of adolescents and (im)migrant non-English speaking mothers in acculturating families. By focusing on the performance of cultural intermediation, I examine the dimensions of technolinguistic brokering and their influence upon the Adolescent Language Technology Broker (ALTB) and mother relationship. Additionally, I explore the factors…

This dissertation explores the technolinguistic brokering experience of adolescents and (im)migrant non-English speaking mothers in acculturating families. By focusing on the performance of cultural intermediation, I examine the dimensions of technolinguistic brokering and their influence upon the Adolescent Language Technology Broker (ALTB) and mother relationship. Additionally, I explore the factors of power present as a result of the complexities of the ALTBs role to connect their mother to the English speaking community. This research uses a qualitative approach to explore concepts of expertise, knowledge, (inter)dependence, relational maintenance and quality, and power in the dialogic cultural relationship. Research indicates that expertise in the form of culture, cultural interactions, multilingual, and relational maintenance and quality contribute to the ALTBs capabilities in building cultural relationships. Moreover, to assist in dealing with power tensions created by differing levels of expertise and knowledge, ALTBs and mothers communicatively construct an (inter)dependent cultural relationship. I highlight practical implications, discuss limitations, and provide recommendations for future directions.

Startle Distinguishes Task Expertise

Description
Recently, it was demonstrated that startle-evoked-movements (SEMs) are present during individuated finger movements (index finger abduction), but only following intense training. This demonstrates that changes in motor planning, which occur through training (motor learning - a characteristic which can provide researchers and clinicians with information about overall rehabilitative effectiveness), can…

Recently, it was demonstrated that startle-evoked-movements (SEMs) are present during individuated finger movements (index finger abduction), but only following intense training. This demonstrates that changes in motor planning, which occur through training (motor learning - a characteristic which can provide researchers and clinicians with information about overall rehabilitative effectiveness), can be analyzed with SEM. The objective here was to determine if SEM is a sensitive enough tool for differentiating expertise (task solidification) in a common everyday task (typing). If proven to be true, SEM may then be useful during rehabilitation for time-stamping when task-specific expertise has occurred, and possibly even when the sufficient dosage of motor training (although not tested here) has been delivered following impairment. It was hypothesized that SEM would be present for all fingers of an expert population, but no fingers of a non-expert population. A total of 9 expert (75.2 ± 9.8 WPM) and 8 non-expert typists, (41.6 ± 8.2 WPM) with right handed dominance and with no previous neurological or current upper extremity impairment were evaluated. SEM was robustly present (all p < 0.05) in all fingers of the experts (except the middle) and absent in all fingers of non-experts except the little (although less robust). Taken together, these results indicate that SEM is a measurable behavioral indicator of motor learning and that it is sensitive to task expertise, opening it for potential clinical utility.
