Revisioning Visions: Narrative Case Studies of Classroom Teachers’ Changing Views of Drama

For two years, I studied three teachers using drama as a tool for teaching and learning in their classrooms. The K-3 (K-5 in the second year of the study) school, McDowell Elementary (all names are pseudonyms to preserve anonymity) belonged to a large urban district in a major Southeastern city whose population was 74% African American, 15% Caucasian, 10% Asian, and 1% Latino. Over 80% of the students qualified for the federal free-or-reduced lunch program. The drama program was fully funded by an area church with support from a local children's theatre, as part of a philanthropic program "to enrich the lives o f . inner-city children both academically and artistically. " The three focus teachers, Geri (kindergarten), Janine (third grade), and Lane (first grade), willingly collaborated with me as I taught with them and reflected on our collaborations. The school, Geri and Lane, as well as many children and colleagues were familiar to me as I had been the drama specialist at McDowell two years earlier. The larger research study on which this article draws is a narrative case study using ethnomethodological and phenomenological methods. Each case shared here tells a unique story; collectively they represent a significant range of teacher perceptions and interpretations of classroom drama that I saw over the two years of the study.
Within-Culture and Gender Differences in Self-Concept

Open-ended self-descriptions were provided by 301 urban and 251 rural Nepalese secondary school children. The responses were coded according to whether they were "large group" collectivist, "small group" collectivist, or individualist and evaluative or nonevaluative self-references. As predicted, the rural, less modernized group gave fewer individualist responses but, contrary to prediction, did not provide either more "small group" collectivist responses or fewer evaluative responses. There was also no tendency for the males to report a more individualistic self. Both groups, particularly the rural, frequently reported future-oriented self-descriptions. The findings, therefore, questioned the generalizability of theoretical notions of culture and the self.
The Effect of Violent Video Games on Aggression

Participants and procedure. o 8 college students o Played each game for 10 min (order of game presentation randomized across participants) o Completed Game Complexity Questionnaire for each game o Six questions (rating scale from 1 to 5): o Overall, how difficult was it to learn the game? o Was it difficult to learn how to use controls for the game? o How quickly did you learn controls for the game? o Did you find the game so difficult that you became frustrated? o How would you rate the pace of the game? o How hard were you trying to win the game? o The goal: Make sure that the most violent game is not the most fast-paced/difficult/frustrating game o In addition, recorded frequency of videogame playing for each participant o Non-violent game is rated significantly less difficult than violent games o No difference between violent and mildly violent game o Mildly violent game is rated significantly more difficult than other games o No difference between violent and nonviolent game
Site-Specific and Sensory Neuron-Dependent Increases in Postsynaptic Glutamate Sensitivity Accompany Serotonin-Induced Long-Term Facilitation at Aplysia Sensorimotor Synapses

Long-term changes in the efficacy of Aplysia sensory neuron (SN) connections accompany behavioral training or applications with 5-HT. The changes evoked by training or 5-HT include formation of new SN varicosities and transmitter release sites. Because new synapse formation requires proper alignment of presynaptic structures with postsynaptic zones containing a high density of transmitter receptors, we examined whether changes in postsynaptic sensitivity to the presumed SN transmitter (glutamate) were correlated with formation and distribution of new SN varicosities in contact with motor cell L7 in cell culture. The formation of stable SN connections after 4 d in culture did not significantly change overall responses to focal applications of glutamate. However, specific sites along L7’s axon apposed to SN varicosities expressed larger responses to glutamate compared with adjacent sites with few SN varicosities. After treatments with 5-HT that evoked long-term changes in both the structure and the function of SN–L7 synaptic interaction, glutamate responses increased selectively at sites along the surface of L7’s axon with preexisting or new SN varicosities. Increases in postsynaptic response to glutamate 24 hr after 5-HT treatment required interaction with an SN. These results suggest that new synapse formation between neurons, either with regeneration or after external stimuli that evoke increases in synaptic efficacy, involves site-specific changes in expression of functional neurotransmitter receptors on the postsynaptic cell that is regulated by interaction with the presynaptic neuron.
Changes in patterns of post-separation parenting over time: Recent Australian data

Abstract This article examines continuity and change in post-separation patterns of parenting across a three-year time span. We analyse longitudinal data from two recent Australian studies: the Household, Income and Labour Dynamics in Australia (HILDA) Survey; and the Caring for Children after Parental Separation (CFC) Project. Mother-residence was found to be the most common and the most stable pattern. Though far less common, father-residence also appeared to be reasonably stable. By contrast, shared care was found to be the most fluid of these three parenting configurations.
Integration of Schematic Faces and Other Complex Objects in Schizophrenia

Twenty-one acute schizophrenic patients and 26 neurotic patients sorted each of six sets of 15 objects into three groups. A set consisted either of schematic faces, nonsense objects, or histoforms, each composed of five independently varying features. For the faces and nonsense objects these features could be integrated into a whole, whereas for the histoforms they could not. The distribution of four of the features was such that a set could be divided into three groups. The fifth feature either remained constant and had no, effect on sorting performance or it varied randomly and acted as a distractor. Performance was assessed from the variance in common between the grouping actually present in a set and the grouping produced by the subject. For the control patients faces were sorted much better than histoforms if no distractor was present. However, performance with faces was massively impaired by a distractor while performance with histoforms was not. For the schizophrenic patients faces were not sorted better than histoforms and the effect of distraction was similar for every type of material. The performance of the controls suggests that the gestalt quality of the faces dominated over their constituent details. This enabled more features to be handled at once, thus achieving better sorting with faces than histoforms. However, it also made it more difficult for subjects to ignore a distracting component in the faces. The performance of the schizophrenics suggests that for them the integrated gestalt of the face was not dominant over its components.
Combining Morpheme-based Machine Translation with Post-processing Morpheme Prediction

This paper extends the training and tuning regime for phrase-based statistical machine translation to obtain fluent translations into morphologically complex languages (we build an English to Finnish translation system). Our methods use unsupervised morphology induction. Unlike previous work we focus on morphologically productive phrase pairs -- our decoder can combine morphemes across phrase boundaries. Morphemes in the target language may not have a corresponding morpheme or word in the source language. Therefore, we propose a novel combination of post-processing morphology prediction with morpheme-based translation. We show, using both automatic evaluation scores and linguistically motivated analyses of the output, that our methods outperform previously proposed ones and provide the best known results on the English-Finnish Europarl translation task. Our methods are mostly language independent, so they should improve translation into other target languages with complex morphology.
Secretome Analysis Uncovers an Hcp-Family Protein Secreted via a Type VI Secretion System in Agrobacterium tumefaciens

ABSTRACT Agrobacterium tumefaciens is a plant-pathogenic bacterium capable of secreting several virulence factors into extracellular space or the host cell. In this study, we used shotgun proteomics analysis to investigate the secretome of A. tumefaciens, which resulted in identification of 12 proteins, including 1 known secretory protein (VirB1*) and 11 potential secretory proteins. Interestingly, one unknown protein, which we designated hemolysin-coregulated protein (Hcp), is a predicted soluble protein without a recognizable N-terminal signal peptide. Western blot analysis revealed that A. tumefaciens Hcp is expressed and secreted when cells are grown in both minimal and rich media. Further biochemical and immunoelectron microscopy analysis demonstrated that intracellular Hcp is localized mainly in the cytosol, with a small portion in the membrane system. To investigate the mechanism of secretion of Hcp in A. tumefaciens, we generated mutants with deletions of a conserved gene, icmF, or the entire putative operon encoding a recently identified type VI secretion system (T6SS). Western blot analysis indicated that Hcp was expressed but not secreted into the culture medium in mutants with deletions of icmF or the t6ss operon. The secretion deficiency of Hcp in the icmF mutant was complemented by heterologous trans expression of icmF, suggesting that icmF is required for Hcp secretion. In tumor assays with potato tuber disks, deletion of hcp resulted in approximately 20 to 30% reductions in tumorigenesis efficiency, while no consistent difference was observed when icmF or the t6ss operon was deleted. These results increase our understanding of the conserved T6SS used by both plant- and animal-pathogenic bacteria.
Insulin Modulates STAT3 Protein Activation and Gene Transcription in Hepatic Cells*

Treatment of rat hepatoma cells with insulin attenuated the interleukin 6 (IL-6) stimulation of acute phase plasma protein genes. To identify the potential mechanism of this action, the influence of insulin on IL-6 signal transduction was determined. An insulin dose-dependent reduction in signal transducer and activator of transcription 3 (STAT3) gene transcription, mRNA accumulation, protein concentration, and IL-6-inducible DNA binding activity was detected. A reduction in the IL-6-activated sis-inducible element binding of STAT3 was observed within 4 h of insulin treatment, whereas a maximal 3-4-fold lower STAT protein concentration was measured after 8-24 h of insulin treatment. Insulin mediated a similar magnitude reduction in the amount of mRNA encoding the IL-6 receptor α subunit and IL-6 binding activity. These effects of insulin appear to contribute to the strongly suppressed transcriptional induction of the IL-6-responsive acute phase plasma protein genes.
TripleProv: efficient processing of lineage queries in a native RDF store

Given the heterogeneity of the data one can find on the Linked Data cloud, being able to trace back the provenance of query results is rapidly becoming a must-have feature of RDF systems. While provenance models have been extensively discussed in recent years, little attention has been given to the efficient implementation of provenance-enabled queries inside data stores. This paper introduces TripleProv: a new system extending a native RDF store to efficiently handle such queries. TripleProv implements two different storage models to physically co-locate lineage and instance data, and for each of them implements algorithms for tracing provenance at two granularity levels. In the following, we present the overall architecture of our system, its different lineage storage models, and the various query execution strategies we have implemented to efficiently answer provenance-enabled queries. In addition, we present the results of a comprehensive empirical evaluation of our system over two different datasets and workloads.
Making Meaning of the Messages: Transmission and Reception of Racial Socialization among African American Dyads.

This dissertation examines the relations among adolescent perceived racial socialization messages and mother transmitted messages in a sample of African American mothers and their children. It first examined the size and direction of the relationship between the two perspectives of racial socialization. The findings indicate that, although adolescent and parent socialization messages are related, there are substantial differences between the two perspectives. However, the size of the relationship differed across the socialization messages. Mothers and adolescents were more likely to agree on the indirect messages parents send through their actions (r = 0.35) than they were to agree on the direct verbal messages that parents use. The next set of analysis explored the ways in which adolescent, maternal, and family characteristics shaped the relationship between adolescent and maternal views of racial socialization messages and practices. These analyses demonstrated that adolescent gender, maternal education, and family structure affected the relationship between adolescent and maternal reports of behavioral socialization practices. Mother-daughter dyads had higher congruence on behavioral socialization than mother-son dyads. Dyads headed by married mothers had higher congruence than those headed by unmarried mothers. College-educated mothers had higher levels of congruence with their adolescent children than non-college educated mothers. The last set of analyses explored the relation between racial socialization and racial identity over time. Overall, adolescents’ perceptions of racial socialization were
A structural look at consumer innovativeness and self-congruence in new product purchases

Consumer innovativeness and new product purchasing literatures are replete with solid yet unrelated theories that have not been considered simultaneously as part of a larger psychological framework. This oversight limits the ability of practitioners to effectively target the valuable consumer innovators market segment. In this study, an approach/avoidance framework of new product purchase intentions is discussed and empirically tested via structural equation modeling. Consumer innovativeness, self-congruence, and satisfaction play the role of approach mechanisms, while perceived risk acts as an avoidance mechanism. The authors combine a set of related yet disconnected theories, while suggesting a means of appealing to consumer innovators through a specific form of self-congruence. A sample of 741 students is employed to examine these issues. Several notable findings are highlighted, including verification of indirect relationships between the independent variables and behavioral intent. Model fit is excellent and results are consistent across the handheld devices, home entertainment, and music industries. © 2008 Wiley Periodicals, Inc.
Alternative routes to the cell surface underpin insulin-regulated membrane trafficking of GLUT4

ABSTRACT Insulin-stimulated delivery of glucose transporters (GLUT4, also known as SLC2A4) from specialized intracellular GLUT4 storage vesicles (GSVs) to the surface of fat and muscle cells is central to whole-body glucose regulation. This translocation and subsequent internalization of GLUT4 back into intracellular stores transits through numerous small membrane-bound compartments (internal GLUT4-containing vesicles; IGVs) including GSVs, but the function of these different compartments is not clear. Cellugyrin (also known as synaptogyrin-2) and sortilin define distinct populations of IGV; sortilin-positive IGVs represent GSVs, but the function of cellugyrin-containing IGVs is unknown. Here, we demonstrate a role for cellugyrin in intracellular sequestration of GLUT4 in HeLa cells and have used a proximity ligation assay to follow changes in pairwise associations between cellugyrin, sortilin, GLUT4 and membrane trafficking machinery following insulin-stimulation of 3T3-L1 adipoctyes. Our data suggest that insulin stimulates traffic from cellugyrin-containing to sortilin-containing membranes, and that cellugyrin-containing IGVs provide an insulin-sensitive reservoir to replenish GSVs following insulin-stimulated exocytosis of GLUT4. Furthermore, our data support the existence of a pathway from cellugyrin-containing membranes to the surface of 3T3-L1 adipocytes that bypasses GSVs under basal conditions, and that insulin diverts traffic away from this into GSVs. Summary: Cellugyrin-containing internal GLUT4-containing vesicles provide an insulin-sensitive reservoir to replenish GLUT4 storage vesicles following insulin-stimulated exocytosis of GLUT4.
What Brings People to Leadership Roles: A Phenomenological Study of Beef Industry Leaders

Leadership has been deeply studied in the literature; however, little research exists studying the role of volunteer peer leaders in non-formalized leadership roles in membership-based organizations. This phenomenological study was designed to explore the experience of beef industry leaders in leadership roles. Twelve active beef industry volunteer leaders were interviewed and described their experience as leaders. Industry leadership was defined from study themes as a role fulfilled by someone who is willing to serve their industry, with the best of the industry in mind and taking on the responsibility and challenges that come along with making decisions to serve and speak for their peers with integrity. Seven themes identified the central phenomenon and seven traits of beef industry leaders were identified. This study offers significance to the field of leadership; to the beef industry; and to agricultural organizations that may guide developing future leaders.
Retrospective reports of school bullying: Stability of recall and its implications for research

In this article a non-probability sample of 60 lesbians, gay men and bisexual men and women, who had all been bullied at school for a period of 5 years or more, were asked to complete a self-report style questionnaire at two time points (12–14 months apart) to assess the stability of their recollections of bullying. Three particular types of recollection were explored: (1) age factors and calendar reference points, (2) incident or event recall, and (3) recall for peripheral factors (e.g. ramificationsandconsequences). The results suggested that participants were able to recallkey events intheirlivesandplace themwithina generalchronologywhichwas not found to vary greatly across the 12–14-month period. They were also able to recall specific types of bullying occurring in specific locations with relative constancy. However, recollections of subsequent outcomes (e.g. telling a teacher) were recalled less well. It is argued that this study lends some support to the idea that retrospective studies have a role to play in applied research and that memory stability may be a useful indicator of reliability where prospective studies are difficult to conduct. However, they should not be seen as an alternative to longitudinalresearch.
Today and Tomorrow

T he main battle tank of the U.S. Army is under pressure due to critical scrutiny from numerous fronts questioning its relevance to the modern security environment. The M1 Abrams played a key role briefly in Operation Iraqi Freedom and rarely in Operation Enduring Freedom. Moreover, due to an apparent perception within NATO that heavy U.S. armor was no longer needed, the Army redeployed the last of the Abrams based in Europe to the United States in 2013.1 Elsewhere, the relevance of heavy armor is being challenged. Anti-armor weapon technology has advanced considerably, to the point that even nonstate actors such as Hezbollah have seen some success against advanced main battle tanks (i.e., Israeli Merkavas in 2006). 2 Finally, the downward tra-jectories of both the overall U.S. military budget and the Army force structure threaten the Abrams force. The cumulative effect of these pressures will make tank force structure and tank modernization efforts prime candidates for budget reductions. This article is not an argument against all such reductions, but it does propose that contemplated Army M1 Abrams tanks maneuver in the streets as they conduct a combat patrol in the city of Tal Afar, Iraq, 3 February 2005. The tanks and their crews are attached to the 3rd Armored Cavalry Regiment.
Factors Influencing Transition and Persistence in the First Year for Community College Students with Disabilities

DEDICATION To my parents, Byron and Rose McCluskey, who taught me hard work and instilled within me the drive to complete my dream. To my family, my husband David and my children Veronica, Caroline, Audrey, and Yvonne, who are my inspiration and strength. v ACKNOWLEDGMENTS I would like to thank my advisor, Dr. Joseph Berger, for his guidance throughout my program of study. I would also like to thank Joanne Sharac, my critical friend, who provided helpful comments and suggestions throughout my dissertation. and Yvonne, for their support, patience, and confidence in me during my dissertation. Community colleges have always played a crucial role in providing access to college, especially for students with disabilities. At the same time the rate of completion is exceptionally low for this particular population (Belch, 2004). In order to improve persistence and achievement measurably, colleges may seek clues in successful transitions by students with disabilities. This project presents a qualitative research study to illuminate factors that contribute to semester-by-semester success of community college students with disabilities during their first year. A conceptual model of successful transitional processes was developed from theoretical constructs reported in the literature and was expanded by data from individual case studies. Seven very strong stages emerged as a result of the research. These stages were: 1) pre-college experiences that influence academic involvement, 2) initial encounters that created first impressions, 3) transition shock, 4) support-seeking and strategic adjustment 5) prioritizing and balancing of college and vii non-college commitments, 6) recognizing success, and 7) a sense of belonging to the college community. These results indicated a successful transition into college is an important first step in persistence for students with disabilities. Persistence of students with disabilities requires further attention and research in order to improve graduation rates of these students at community colleges.
Low-Income Minority Seniors' Enrollment in a Cybercafé: Psychological Barriers to Crossing the Digital Divide

Investigated were why some low income, predominantly immigrant seniors (n = 91) choose to enroll in free training and start to use computers and the Internet while others choose not to enroll. The study was conducted in collaboration with a senior center in downtown Los Angeles that provides free Internet access and training to its seniors. The results suggest that psychological variables (e.g., computer anxiety, computer self-efficacy, and aging anxiety) are stronger predictors of older adults' enrollment than their age or actual experience in using computers. Discussed are ways to motivate seniors to participate in computer training by reducing potential barriers.
