Neural Correlates of Decision Making on a Gambling Task

Individual differences in affective decision making were examined by recording event-related potentials (ERPs) while 74 typically developing 8-year-olds (38 boys, 36 girls) completed a 4-choice gambling task (Hungry Donkey Task; E. A. Crone & M. W. van der Molen, 2004 ). ERP results indicated: (a) a robust P300 component in response to feedback (punishment vs. reward outcomes), (b) anticipation effects (stimulus-preceding negativity) prior to outcomes presented on frequent (vs. infrequent) punishment choices, (c) anticipation effects prior to selections associated with short and long-term losses (vs. gains), and (d) individual differences in ERP components were significantly correlated with behavioral performance and verbal ability. These findings suggest that neurophysiological responses may be an index of children's trait-based and/or developmental level of decision-making skills in affective–motivational situations.     

Cultural-Specific Lexis for Intercultural Communication: Case Studies From Two Different Classrooms

In light of the move towards a bi/multilingual turn and recent reevaluation of translation in the field of applied linguistics, this article looks at the translation of culture-specific lexis (CSL) and its role in developing learners’ intercultural discussion and reflection. It examines learning journals kept by students in two different contexts, intermediate learners of Japanese in a U.K. university and intermediate learners of English in a South Korean university. Despite a difference in contexts, three recurrent themes were identified in the learning journals in both classrooms: (1) reflection of languages and cultures, (2) considerations of the target reader, and (3) critical reflection of one’s own translation. The results of the study show that translation tasks involving CSL can enhance students’ intercultural awareness and, consequently, contribute to the development of intercultural competence.     

Measuring clearance mechanics based on dynamic leg length

The aim of this study was to quantify clearance mechanics during gait. Seventeen children diagnosed with hemiplegic cerebral palsy underwent a three-dimensional gait analysis evaluation. Dynamic leg lengths were measured from the hip joint center to the heel, to the ankle joint center and to the forefoot throughout the gait cycle. Significant asymmetry was observed during stance, initial and terminal swing phases, where the hemiplegic limb was found shorter by using a paired t-test at 51 sample points (p < .05). The hemiplegic side was restricted in achieving maximal length during terminal swing. The ratio between the maximal dynamic leg length during the stance phase to minimal dynamic leg length during the swing phase was found higher on the non-involved side and lower on the hemiplegic side (p < .05). Quantifying clearance mechanics based on dynamic leg length can provide an additional insight into the analysis of gait patterns and might assist in detecting time of abnormal kinematic deviations.     

Serum Lactate Dehydrogenase in Non-Hodgkin’s Lymphoma: A Prognostic Indicator

Non-Hodgkin’s lymphoma constitutes a group of disorders originating from the malignant transformation of lymphocytes and involving either the lymph nodes or extranodal sites. NHL commonly presents in the sixth to seventh decade of life with a male preponderance (50–75 %). Recent studies have shown importance of serum LDH in prognosis of NHL. Authors report a case of a 63 year old male presenting with complaints of fever and backache for past 4 months. General and systemic examination revealed bilateral axillary lymphadenopathy and splenomegaly respectively. Serum LDH level was highly elevated (3441 U/l). Excisional axillary and bone marrow biopsy were done before oncology referral. Complete workup revealed diffuse Non-Hodgkin’s lymphoma with bone marrow infiltration. Patient died because of acute renal failure due to NHL and DM 2 (Type 2 diabetes mellitus).     

Times of Violence

This essay reads the NBC drama The West Wing against the cultural anxieties and ambivalences about the contemporary presidency, arguing that the program presents a powerful and meaningful “presidentiality,” a discursive construction of the presidency with ideological and rhetorical relevance. Specifically, The West Wing mimetically captures a view of the presidency, offering, in the process, a romantic vision of the institution that reflects the postmodernity of U.S. politics and the uncertainty that pervades questions of heroism and hierarchy at the turn of the twenty‐first century. In part, the political drama disrupts images of traditional power politics, presenting a more chaotic, inclusive, and communal portrayal of the presidency. Against this narrative backdrop, however, we contend that the program situates its postmodern rendition of presidentiality within a cathartic portrayal of the presidency, relying on conservative demarcations of presidential leadership ordered by commitments to intellectualism, militarism, masculinity, and whiteness.     

Teenagers' Use of MSN Features,Discussion Topics,and Online Friendship Development: The Impact of Media Richness and Communication Control

With a sample of 248 Hong Kong adolescents, this study probed the impact of media richness and communication control on teenagers' use of MSN® for online friendship development. Both media richness and communication control contributed to MSN's overall functionality and teenagers' self-presentation and friendship development. Media richness positively influenced both social and task communications and shortened the time needed to turn a stranger to friend, whereas communication control showed a positive relationship to social friendship communication. Rich features, such as webcam and MSN Spaces, facilitated the increase of acquaintances, new friends, opposite-sex friends, and total number of friends, whereas messaging helped build close friendships. Overall, media richness and communication control appeared to be valid constructs in explaining teenagers' MSN feature use and online friendship development.     

University Students’ Conceptualization and Interpretation of Topographic Maps

This study investigates the strategies and assumptions that college students entering an introductory physical geology laboratory use to interpret topographic maps, and follows the progress of the students during the laboratory to analyze changes in those strategies and assumptions. To elicit students’ strategies and assumptions, we created and refined a topographic visualization test that was administered before and after instruction to 26 students during the first semester of the study and to 92 students during the second semester. To more deeply understand how students think about and conceptualize topographic maps, we focused on eight individual students who were interviewed about their pretest and posttest answers as well as videotaped during three laboratory sessions. We found that even students who claim never to have worked with topographic maps often perform impressively on their pretests by making useful assumptions about symbolic topographic information. Some students, however, begin with less productive assumptions that may be unfamiliar to some instructors (e.g., thinking that the spacing of contour lines indicates elevation instead of slope). Initial success should not be misinterpreted, however, as an integrated understanding of topographic maps. Only in posttest interviews do most students express explanations integrating multiple normative assumptions. In addition to highlighting the strategies and assumptions that college students use to interpret topographic maps, we outline the implications of these findings for the design of learning objectives, curricular activities, and assessments for topographic lessons in introductory college geology courses and the training of future geoscientists.     

Relative Endurance of High- and Low-Strength Women

Abstract

The purpose of this study was to analyze the relative endurance ability of women in terms of muscle mass, static muscle strength, and critical occluding tension levels (COTL). Women physical education majors volunteered as subjects for this study (N = 56). The percentages of grip strength used for the relative endurance tests were 30%, 45%, 60%, and 75% with local circulation to the forearm muscles intact and artificially occluded by a pressure cuff. Analysis of the data revealed that there was no significant difference in the endurance times of high- and low-strength women. The relationship between grip strength and relative endurance time for each tension level was insignificant (r = ?.23 to ?.34). These findings were discussed in light of the relatively small differences in muscle mass and similarity in COTL of high- and low-strength women.
