Uncovering Preservice Teachers' Beliefs About Diversity Through Reflective Writing

This article reports findings from a mixed-method investigation of a cohort of teacher candidates who were placed in an urban and culturally diverse practicum site at an elementary school. Fifteen preservice teachers completed pre- and posttest measures related to hope, motivation for teaching, and efficacy for teaching. Throughout the semester, they were required to investigate personal beliefs and past experiences with cultural diversity in the form of writing reflective response letters and cultural autobiographies. Providing the students with these opportunities was beneficial; however, findings are consistent with previous studies that suggest that (a) multiple opportunities across time are needed to uncover and dialogue about beliefs to present significant change rather than single, isolated opportunities and (b) teacher candidates with multicultural schooling and life experiences are more likely to have favorable beliefs and attitudes regarding cultural diversity than are candidates with monocultural schooling and life experiences.
Narrative and Identity Management: Discourse and Social Identities in a Tale of Tomorrow

The ways in which interactional details and roles enacted by participants in relation to the ongoing production of a story connect with larger roles and identities have not been at the center of the problematics of identity construction in narrative. In an attempt to redress the balance, this article uses a broad definition of the conversation analytic concept of discourse identities and takes into account the ethnography of its data to explore the discourse identities management in the course of a conversational tale of tomorrow constructed by 3 Greek female adolescents. Stories of projected events, along with stories of shared events, form the specific group's main narrative practices. I show that the joint construction of the story at hand rests on the participants' enactment of a set of discourse identities that are intertwined with the story's emerging internal structure, particularly the components of complicating action and evaluation. These identities are interrelated to the participants' larger social roles and identities as friends and members of a close-knit group who share an interactional history.
Vascular patterning defects associated with expression of activated Notch4 in embryonic endothelium

Notch proteins function as receptors for membrane-bound ligands (Jagged and Delta-like) to regulate cell-fate determination. We have investigated the role of Notch signaling in embryonic endothelium of the mouse by expressing an activated form of the Notch4 protein in vasculature under the regulation of the Flk1 (VEGFR) locus. Expression of activated Notch4 results in a growth and developmental delay and embryonic lethality at about 10 days postcoitum. The extent of the developing vasculature in mutant embryos was restricted, fewer small vessels were seen, and vascular networks were disorganized. The brain periphery of mutant embryos contained large dilated vessels with evidence of compromised vessel-wall integrity and large areas of necrosis; yolk-sac vasculature was abnormal. Expression of an activated form of Notch4 in embryonic vasculature leads to abnormal vessel structure and patterning, implicating the Notch pathway in phases of vascular development associated with vessel patterning and remodeling.
Performance teachers' identity and professional knowledge in advanced music teaching

This paper explores the interrelationship between performance teachers' professional identity and the various forms of professional knowledge they bring to their work. The data derive from an ethnographic case study conducted across a period of 12 weeks in each of two distinct music training institutions in Greece – a University Music Department and a Conservatoire. A total of 28 teachers participated in the study across institutions (Conservatoire, n=18; Music Department, n=10) and within each institutional sample four teachers were observed during their teaching and performing practices. Institutional documents provided contextual information. Findings showed that performance teachers drew on different forms of professional knowledge in their teaching practice in accordance with the construction of the more valued identity in their workplace as either a teacher or a performer. Also evident was that a particular identity and forms of professional knowledge were foregrounded at the point where teacher and performer identities met or separated. The development of a new type of professionalism at the interface where performer and teacher identities meet thereby empowering teachers to take on roles and responsibilities that would extend their professional stories of self is discussed.
Emotional and Social Mind Training: A Randomised Controlled Trial of a New Group-Based Treatment for Bulimia Nervosa

Objective There is a need to improve treatment for individuals with bulimic disorders. It was hypothesised that a focus in treatment on broader emotional and social/interpersonal issues underlying eating disorders would increase treatment efficacy. This study tested a novel treatment based on the above hypothesis, an Emotional and Social Mind Training Group (ESM), against a Cognitive Behavioural Therapy Group (CBT) treatment. Method 74 participants were randomised to either ESM or CBT Group treatment programmes. All participants were offered 13 group and 4 individual sessions. The primary outcome measure was the Eating Disorder Examination (EDE) Global score. Assessments were carried out at baseline, end of treatment (four months) and follow-up (six months). Results There were no differences in outcome between the two treatments. No moderators of treatment outcome were identified. Adherence rates were higher for participants in the ESM group. Discussion This suggests that ESM may be a viable alternative to CBT for some individuals. Further research will be required to identify and preferentially allocate suitable individuals accordingly.

Integrating Agent and Web Service into Grid Service Workflow System

The dynamical Grid environment requires flexible and adaptive workflow system. This paper integrates Agents and Web Services into Grid Service Workflow System based on Colored Petri Nets. The combination of Agents and Web Services enhances the adaptability and dynamics of the framework. How Web Service can be located dynamically and the services provided by it can be invoked are discussed. Using an example of ordering railway ticket, we show how our framework can achieve adaptability from process, resource and task perspectives using both Agents and Web Services.
Structured representation-based robust agile-beam LADAR imaging

LAser Detection And Ranging (LADAR) imagers operate by measuring the distance to an object by timing how long a transmitted pulse takes to make a round trip between the transmitter and the receiver. LADAR images are often characterized by a multiplicative noise known as speckle which often makes the interpretation of data difficult. In this paper, we propose a more general formulation of the problem of reconstructing the piecewise smooth and texture component (speckle) directly from a set of LADAR measurements. The proposed method is evaluated on the real data collected by using a new agile-beam LADAR architecture.
Histopathological Study of Ocular Surface Squamous Neoplasia in Biopsies Received at Tertiary Care Centre

Introduction: Ocular surface squamous neoplasia(OSSN) is an encompassing term for pre-cancerous and cancerous epithelial lesions of the conjunctiva and cornea which includes Dysplasia, Carcinoma in-situ (CIS) and Invasive Squamous Cell Carcinoma. OSSN is mostly unilateral, occurs in middle aged to older patients. It is associated with factors such as HIV and xeroderma pigmentosum. Aims and Objectives: 1) To evaluate incidence of Dysplasia and Squamous Cell Carcinoma in biopsies received 2) To study the spectrum of histopathological findings in Ocular Surface Squamous Neoplasia Materials and Method: We examined 52 ocular surface biopsies received in our tertiary care centre during the period of 22 months (August-2015 to May-2017). Slides stained with Hematoxylin and Eosin were examined and dysplasia found in biopsies were categorized into mild, moderate and severe. Invasive squamous cell carcinomas were again categorized according to differentiation into well differentiated, moderately differentiated and poorly differentiated. In addition to these 52 biopsies, 10 biopsies were excluded from the study which showed normal or only hyperplastic squamous epithelium. Results: Out of 52 biopsies examined, 2 cases showed squamous papilloma,13 cases showed dysplasia-mild being the commonest and 37 cases showed invasive carcinoma, moderate differentiation being the commonest. Conclusion: OSSN is common in middle age and male gender and usually occurs in limbal conjunctiva. Histopathology remains the gold standard for accurate diagnosis and grading of OSSN. Despite increasing awareness, Invasive carcinoma is more prevalent than dysplasia. Prognosis largely depends upon grade and differentiation of tumor and specific microscopic type.
Safety alerts reduce willingness to visit parks irrigated with recycled water

This study demonstrates the effects of framing safety precautions on the presentation of a controversial product (recycled water [RW]) to the inhabitants of two Greek towns by asking them whether they would visit various configurations of a public park irrigated with RW. The same questions are posed in an additional version augmented with a safety alert. Among many others, results mainly show that willingness to visit (WTV) a park irrigated with RW or willingness to pay for RW decrease when respondents are confronted with the safety statement that ‘the irrigated parts are isolated and have been properly marked for the visitor so that he/she does not come into touch with RW’. Moreover, WTV does not decrease when there is previous experience with the park. The upgrade of RW from secondary to tertiary treatment is valuated only when safety alerts are present. The paper yields promotion insights useful for relevant utilities, organizations, and governments which are interested in forming a social marketing mix for this product while contributing to the theoretical and empirical understanding of framing effects with their experimental demonstration in the two case studies.
Modulation of microtubule stability by kinetochores in vitro

The interface between kinetochores and microtubules in the mitotic spindle is known to be dynamic. Kinetochore microtubules can both polymerize and depolymerize, and their dynamic behavior is intimately related to chromosome movement. In this paper we investigate the influence of kinetochores on the inherent dynamic behavior of microtubules using an in vitro assay. The dynamics of microtubule plus ends attached to kinetochores are compared to those of free plus ends in the same solution. We show that microtubules attached to kinetochores exhibit the full range of dynamic instability behavior, but at altered transition rates. Surprisingly, we find that kinetochores increase the rate at which microtubule ends transit from growing to shrinking. This result contradicts our previous findings (Mitchison, T. J., and M. W. Kirschner, 1985b) for technical reasons which are discussed. We suggest that catalysis of the growing to shrinking transition by kinetochores may account for selective depolymerization of kinetochore microtubules during anaphase in vivo. We also investigate the effects of a nonhydrolyzable ATP analogue on kinetochore microtubule dynamics. We find that 5' adenylylimido diphosphate induces a rigor state at the kinetochore-microtubule interface, which prevents depolymerization of the microtubule.

Introduction to special issue Building the entrepreneurial university: a global perspective

The entrepreneurial university is the next stage in the development of a medieval institution. Integrating a commitment to economic growth and social development with research and teaching, the entrepreneurial university supersedes the late 19th century Humboldtian synthesis that aligned research with teaching as the two primary academic missions (Etzkowitz, Minera, 1983, 21, 198–233). From its medieval origins, whether a student- or faculty-led foundation as in Paris or Bologna, the university has proved to be a flexible and evolving organizational form capable of reconciling conservatism with innovation. The passage of student generations combined with relative faculty autonomy is the basis on which these two institutional characteristics co-exist in a creative tension.

Moral Lineage Tracing

Lineage tracing, the tracking of living cells as they move and divide, is a central problem in biological image analysis. Solutions, called lineage forests, are key to understanding how the structure of multicellular organisms emerges. We propose an integer linear program (ILP) whose feasible solutions define, for every image in a sequence, a decomposition into cells (segmentation) and, across images, a lineage forest of cells (tracing). In this ILP, path-cut inequalities enforce the morality of lineages, i.e., the constraint that cells do not merge. To find feasible solutions of this NP-hard problem, with certified bounds to the global optimum, we define efficient separation procedures and apply these as part of a branch-and-cut algorithm. To show the effectiveness of this approach, we analyze feasible solutions for real microscopy data in terms of bounds and run-time, and by their weighted edit distance to lineage forests traced by humans.
The influence of experiential marketing and activity involvement on the loyalty intentions of wine tourists in Taiwan

This study assesses a behavioural model that uses latent variables of experience of experiential marketing, activity involvement, satisfaction and loyalty intentions of wine tourists in Taiwan. A total of 871 usable questionnaires were collected. Confirmatory factor analysis and structural equation model analysis were performed using LISREL 8.70 for Windows. Analytical results, which further elucidate the behavioural models of wine tourism, suggest that experience of experiential marketing, activity involvement and satisfaction significantly affect the loyalty intentions of wine tourists. Satisfaction played a mediating role in the behavioural model. This study provides further insight into the behavioural modelling of wine tourism.

This document seeks to consolidate the information related to POP3 AUTH into a single document. To this end, this document obsoletes and replaces RFC 1734, and updates the information contained in Section 6.3 of RFC 2449. [STANDARDS-TRACK]
Who voted for peace? Public support for the 1998 Northern Ireland agreement

Abstract The April 1998 Good Friday Agreement represents the most promising attempt in 30 years to settle the Northern Ireland conflict. Yet for more than a year after it was ratified by an overwhelming majority of voters, its key principles remained unimplemented, and on two occasions the executive has been suspended. In this article we examine public support for the Agreement and analyse the patterns of voting in the referendum. Using the 1998 Northern Ireland Referendum and Election Survey, we show that while almost all Catholics voted for the Agreement, only 57 percent of Protestants did so, and many of those expressed widespread concern and indecision. For Protestants, a yes vote in the referendum reflected a desire for the return of devolved government, the perception that the Agreement represented a ‘new beginning’, and trust in David Trimble, the Ulster Unionist leader. Catholic views of whether the Agreement would bring Irish unity centred on territoriality issues. The absence of widespread, cross‐community support for the Agreement's key principles helps to explain the difficulties in both establishing and maintaining a devolved, powersharing executive.
Word Discovery with Beta Process Factor Analysis

We propose the application of a recently developed non-parametric Bayesian method for factor analysis to the problem of word discovery from continuous speech. The method, based on Beta Process priors, has a number of advantages compared to previously proposed methods, such as Non-negative Matrix Factorisation (NMF). Beta Process Factor Analysis (BPFA) is able to estimate the size of the basis, and therefore the number of recurring patterns, or word candidates, found in the data. We compare the results obtained with BPFA and NMF on the TIDigits database, showing that our method is capable of not only finding the correct words, but also the correct number of words. We also show that the method can infer the approximate number of words for different vocabulary sizes by testing on randomly generated sequences of words.
Fowlpox Virus Encodes a Bcl-2 Homologue That Protects Cells from Apoptotic Death through Interaction with the Proapoptotic Protein Bak

ABSTRACT Poxviruses are renowned for encoding numerous immunomodulatory proteins capable of undermining potent immune defenses. One effective barrier against infection is apoptosis, a process controlled at the mitochondria by pro- and antiapoptotic members of the highly conserved Bcl-2 family of proteins. Although poxviruses are known to encode an array of effective inhibitors of apoptosis, members of the Avipoxvirus genus, which includes fowlpox virus, encode proteins with Bcl-2 homology. Here, we show that FPV039, a fowlpox virus protein with limited Bcl-2 homology, inhibited apoptosis in response to a variety of cytotoxic stimuli, including virus infection itself. Similar to other antiapoptotic Bcl-2 proteins, FPV039 localized predominantly to the mitochondria in both human and chicken cells and protected human cells from tumor necrosis factor alpha-induced loss of the mitochondrial membrane potential. In addition, coimmunoprecipitation revealed that FPV039 interacted constitutively with the proapoptotic Bcl-2 protein, Bak, in both human and chicken cells. Concordantly, FPV039 also inhibited apoptosis induced by the transient overexpression of Bak. To confirm these results in the context of virus infection, we generated a recombinant vaccinia virus lacking F1L, the endogenous apoptotic inhibitor in vaccinia virus, and expressing FPV039. In the context of vaccinia virus infection, FPV039 retained the ability to localize to the mitochondria and interacted with Bak. Moreover, FPV039 prevented the activation of Bak and protected infected cells from apoptosis induced by staurosporine and virus infection. Together, our data indicate that FPV039 is a functional Bcl-2 homologue that inhibits apoptosis by neutralizing the proapoptotic Bcl-2 family member Bak.
Reward Modulates Attention Independently of Action Value in Posterior Parietal Cortex

While numerous studies have explored the mechanisms of reward-based decisions (the choice of action based on expected gain), few have asked how reward influences attention (the selection of information relevant for a decision). Here we show that a powerful determinant of attentional priority is the association between a stimulus and an appetitive reward. A peripheral cue heralded the delivery of reward or no reward (these cues are termed herein RC+ and RC−, respectively); to experience the predicted outcome, monkeys made a saccade to a target that appeared unpredictably at the same or opposite location relative to the cue. Although the RC had no operant associations (did not specify the required saccade), they automatically biased attention, such that an RC+ attracted attention and an RC− repelled attention from its location. Neurons in the lateral intraparietal area (LIP) encoded these attentional biases, maintaining sustained excitation at the location of an RC+ and inhibition at the location of an RC−. Contrary to the hypothesis that LIP encodes action value, neurons did not encode the expected reward of the saccade. Moreover, at odds with an adaptive decision process, the cue-evoked biases interfered with the required saccade, and these biases increased rather than abating with training. After prolonged training, valence selectivity appeared at shorter latencies and automatically transferred to a novel task context, suggesting that training produced visual plasticity. The results suggest that reward predictors gain automatic attentional priority regardless of their operant associations, and this valence-specific priority is encoded in LIP independently of the expected reward of an action.
A novel AODV routing algorithm based on local route maintenance in Tactical MANETs

Aim at improving the performance and efficiency of AODV protocol in Tactical MANETs which has large scale and fast changing topology, a novel AODV algorithm - LRM-AODV based on local route maintenance is proposed. According to the feature that there always exist many idle nodes, LRM-AODV adopts reverse route search procedure for idle nodes to produce many local routes and increase the route redundancy in the network, this speed up the route discovery and make the fast route repair possible. The simulation results indicate that the performance of LRM-AODV is superior to AODV in packet delivery ratio, end-to-end packet delay and routing overhead.
Preliminary Model Development of Client Orientation in Civil Engineering Businesses

As a key pillar underlining the marketing concept, client orientation is a philosophy in that an organization's customers should be put in the centre of its activities; therefore, it is able to create superior value for them continuously. Competing in the rapidly changing and highly competitive marketplace, firms in civil engineering sector need to attain this. This paper analyses various elements which contribute to the achievement of client orientation in civil engineering by starting with a review of the competitive marketplace and the approaches that the civil engineering sector have been adopted to meet the new challenges, then definition of client orientation. In conclusion, the preliminary "C-O-N-S-T-R- U-C-T-S" framework is proposed which aims to provide an outline approach to achieving client orientation in the civil engineering sector.
