Collegiate Fan Allegiance and Twitter\u27s Role Using the Revised Psychological Continuum Model (PCM): A Case Study of Clemson Men\u27s Basketball Fan

The purpose of this study is to investigate the Twitter\u27s role in the formation of team allegiance through the revised Psychological Continuum Model (PCM) by creating James and Funk (2006). Although collegiate sports programs are using social media to communicate with their fans, little research about how social media impacts the formation of team allegiance has been done. The primary focus will be to analyze how individuals interact with a sports team via Twitter and how those interactions form allegiance. Twitter, a new communication technology platform, is, at present, one of the most popular sites and communication technologies among both individuals and organizations (Clavio, 2011). Twitter also offers a beneficial platform as a strategic marketing tool, enabling fans to elevate team allegiance within the sports realm. This study will also specifically determine whether observing people’s interactions on Twitter is an effective way to study the developing relationship between individuals’ awareness and emotions related to watching sports games and their allegiance toward specific sports team. This research will also help sports marketers learn about sports consumers’ behaviors, needs, and motivations online, which will help shape internet marketing communication

Rethinking summarization and storytelling for modern social multimedia

Traditional summarization initiatives have been focused on specific types of documents such as articles, reviews, videos, image feeds, or tweets, a practice which may result in pigeonholing the summarization task in the context of modern, content-rich multimedia collections. Consequently, much of the research to date has revolved around mostly toy problems in narrow domains and working on single-source media types. We argue that summarization and story generation systems need to re-focus the problem space in order to meet the information needs in the age of user-generated content in different formats and languages. Here we create a framework for flexible multimedia storytelling. Narratives, stories, and summaries carry a set of challenges in big data and dynamic multi-source media that give rise to new research in spatial-temporal representation, viewpoint generation, and explanatio

Inclusion Not Exclusion: Comparative Educational Perspectives at the Heart of Sustainable Development in the Gulf States

Welcome to this special edition of FIRE: Forum for International Research in Education. This issue celebrates the rich variety of research brought together at the 6th Annual Gulf Comparative Education Society (GCES) Symposium in April 2015. Hosted by Middlesex University at their Dubai campus, the symposium was an opportunity to share and critically discuss matters related to comparative and educational research in a region where opportunities for such activities can be challenging to access. Speakers from Kuwait to Oman came together, and in the form of the conference found both a voice and a support network. The richness of this meeting of minds has been captured in part though this special edition. Building on the quality of research that FIRE has become recognized for, we hope you will find the content of this issue interesting, thought provoking, and even controversial, as all good research should be. Above all, we hope it inspires even more academics from within this region to come forward and participate in the debate at future GCES conferences

Heparin and Heparan Sulfate: Analyzing Structure and Microheterogeneity [chapter]

available in PMC 2013 August 28The structural microheterogeneity of heparin and heparan sulfate is one of the major reasons for the multifunctionality exhibited by this class of molecules. In a physiological context, these molecules primarily exert their effects extracellularly by mediating key processes of cellular cross-talk and signaling leading to the modulation of a number of different biological activities including development, cell proliferation, and inflammation. This structural diversity is biosynthetically imprinted in a nontemplate-driven manner and may also be dynamically remodeled as cellular function changes. Understanding the structural information encoded in these molecules forms the basis for attempting to understand the complex biology they mediate. This chapter provides an overview of the origin of the structural microheterogeneity observed in heparin and heparan sulfate, and the orthogonal analytical methodologies that are required to help decipher this information

Generalisable Methods for Vegetation Classification Using Computer-Generated Pseudoquadrats

Many countries have developed phytosociological classifications of their vegetation to describe semi-natural and natural vegetation communities. Can methods be developed for any classification system to allocate newly surveyed quadrats, i.e. data gathered from new field surveys, into the most likely vegetation community? Algorithms or software already exist to allocate quadrats for some classifications, but these are not generalisable to any system. We test the robustness of several generalisable approaches to allocate quadrats to an existing phytosociological classification, using the British National Vegetation Classification (NVC) as a case study. Vegetation from 167 quadrats was classified using two-way indicator species analysis (TWINSPAN) and the resultant groups allocated to communities within the NVC using the NVC-specific \u27MAVIS\u27 software. Sets of artificial \u27pseudoquadrats\u27 for potential communities were computer-generated based on either the published NVC community descriptions or from the subset of species surveyed. Distance in ordination space of observed quadrats from pseudoquadrats was used to predict community type. The conventional NVC-specific MAVIS classification produced 11 sub-communities at the site, and this was assumed to be the most reliable descriptor of the vegetation communities. There was a close match between the pseudoquadrat-based community predictions and the MAVIS predictions, although pseudoquadrats based on the subset of species observed at the site appeared to be slightly more reliable. Our results demonstrate that the use of pseudoquadrats provides a flexible, generalisable means to allocate objectively vegetation quadrats into any extant classification system

A Social Identity Approach to Sport Psychology: Principles, Practice, and Prospects.

Drawing on social identity theory and self-categorization theory, we outline an approach to sport psychology that understands groups not simply as features of sporting contexts but rather as elements that can be, and often are, incorporated into a person's sense of self and, through this, become powerful determinants of their sport-related behavior. The underpinnings of this social identity approach are outlined, and four key lessons for sport that are indicative of the analytical and practical power of the approach are presented. These suggest that social identity is the basis for sports group (1) behavior, (2) formation and development, (3) support and stress appraisal, and (4) leadership. Building on recent developments within sport science, we outline an agenda for future research by identifying a range of topics to which the social identity approach could fruitfully contribute

Heparan sulfate proteoglycans: structure, protein interactions and cell signaling

Heparan sulfate proteoglycans are ubiquitously found at the cell surface and extracellular matrix in all the animal species. This review will focus on the structural characteristics of the heparan sulfate proteoglycans related to protein interactions leading to cell signaling. The heparan sulfate chains due to their vast structural diversity are able to bind and interact with a wide variety of proteins, such as growth factors, chemokines, morphogens, extracellular matrix components, enzymes, among others. There is a specificity directing the interactions of heparan sulfates and target proteins, regarding both the fine structure of the polysaccharide chain as well precise protein motifs. Heparan sulfates play a role in cellular signaling either as receptor or co-receptor for different ligands, and the activation of downstream pathways is related to phosphorylation of different cytosolic proteins either directly or involving cytoskeleton interactions leading to gene regulation. The role of the heparan sulfate proteoglycans in cellular signaling and endocytic uptake pathways is also discussed.Proteoglicanos de heparam sulfato são encontrados tanto superfície celular quanto na matriz extracelular em todas as espécies animais. Esta revisão tem enfoque nas características estruturais dos proteoglicanos de heparam sulfato e nas interações destes proteoglicanos com proteínas que levam à sinalização celular. As cadeias de heparam sulfato, devido a sua variedade estrutural, são capazes de se ligar e interagir com ampla gama de proteínas, como fatores de crescimento, quimiocinas, morfógenos, componentes da matriz extracelular, enzimas, entreoutros. Existe uma especificidade estrutural que direciona as interações dos heparam sulfatos e proteínas alvo. Esta especificidade está relacionada com a estrutura da cadeia do polissacarídeo e os motivos conservados da cadeia polipeptídica das proteínas envolvidas nesta interação. Os heparam sulfatos possuem papel na sinalização celular como receptores ou coreceptores para diferentes ligantes. Esta ligação dispara vias de sinalização celular levam à fosforilação de diversas proteínas citosólicas ou com ou sem interações diretas com o citoesqueleto, culminando na regulação gênica. O papel dos proteoglicanos de heparam sulfato na sinalização celular e vias de captação endocítica também são discutidas nesta revisão.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Federal de São Paulo (UNIFESP) Departamento de BioquímicaUniversidade Federal de São Paulo (UNIFESP) Departamento de OftalmologiaUNIFESP, Depto. de BioquímicaUNIFESP, Depto. de OftalmologiaSciEL

Leaky doors: private captivity as a prominent source of bird introductions in Australia

The international pet trade is a major source of emerging invasive vertebrate species. We used online resources as a novel source of information for accidental bird escapes, and we investigated the factors that influence the frequency and distribution of bird escapes at a continental scale. We collected information on over 5,000 pet birds reported to be missing on animal websites during the last 15 years in Australia. We investigated whether variables linked to pet ownership successfully predicted bird escapes, and we assessed the potential distribution of these escapes. Most of the reported birds were parrots (> 90%), thus, we analysed factors associated with the frequency of parrot escapes. We found that bird escapes in Australia are much more frequent than previously acknowledged. Bird escapes were reported more frequently within, or around, large Australian capital cities. Socio-economic factors, such as the average personal income level of the community, and the level of human modification to the environment were the best predictors of bird escapes. Cheaper parrot species, Australian natives, and parrot species regarded as peaceful or playful were the most frequently reported escapees. Accidental introductions have been overlooked as an important source of animal incursions. Information on bird escapes is available online in many higher income countries and, in Australia, this is particularly apparent for parrot species. We believe that online resources may provide useful tools for passive surveillance for non-native pet species. Online surveillance will be particularly relevant for species that are highly reported, such as parrots, and species that are either valuable or highly commensal.Miquel Vall-llosera, Phillip Casse

Impulsivity and self-harm in adolescence: a systematic review

Research supports an association between impulsivity and self-harm, yet inconsistencies in methodology across studies have complicated understanding of this relationship. This systematic review examines the association between impulsivity and self-harm in community-based adolescents aged 11-25 years and aims to integrate findings according to differing concepts and methods. Electronic searches of EMBASE, MEDLINE, PsychINFO, CINAHL, PubMed and The Cochrane Library, and manual searches of reference lists of relevant reviews, identified 4,496 articles published up to July 2015, of which 28 met inclusion criteria. Twenty-four of the studies reported an association between broadly specified impulsivity and self-harm. However, findings varied according to the conception and measurement of impulsivity and the precision with which self-harm behaviours were specified. Specifically, lifetime non-suicidal self-injury was most consistently associated with mood-based impulsivity related traits. However, cognitive facets of impulsivity (relating to difficulties maintaining focus or acting without forethought) differentiated current self-harm from past self-harm. These facets also distinguished those with thoughts of self-harm (ideation) from those who acted on thoughts (enaction). The findings suggested that mood-based impulsivity is related to the initiation of self-harm, while cognitive facets of impulsivity are associated with the maintenance of self-harm. In addition, behavioural impulsivity is most relevant to self-harm under conditions of negative affect. Collectively, the findings indicate that distinct impulsivity facets confer unique risks across the life-course of self-harm. From a clinical perspective, the review suggests that interventions focusing on reducing rash reactivity to emotions or improving self-regulation and decision-making may offer most benefit in supporting those who self-harm
