description: A investigação se passa em uma formação continuada de professores de Ciências e Matemática da Educação de Jovens e Adultos (EJA), semipresencial, com doze turmas contendo 30 alunos cada, distribuídas em nove municípios do Estado do Espírito Santo - Brasil. O objetivo deste trabalho foi apresentar o primeiro estágio dessa investigação - o planejamento e a implantação da rede de investigadores no Estado do Espírito Santo para coletar dados na perspectiva naturalística, a fim de organizar as unidades de análise em categorias que se definem ao longo da investigação. Os instrumentos da investigação são questionários, entrevistas, observações e relatos de experiência, mas neste trabalho nos focamos em algumas questões de um primeiro questionário. Os dados produzidos são organizados e analisados de forma colaborativa pela equipe de investigação, utilizando um software de análise qualitativa “WEBQDA”. Trata-se de uma investigação qualitativa, em desenvolvimento, envolvendo professores de Ciências e Matemática de escolas da educação básica situadas em nove polos no Estado. A investigação é uma primeira versão de uma radiografia da sala de aula de Ciências e Matemática na modalidade da EJA que, mais do que conhecer a realidade educacional do Estado, propõe ações e intervenções que estejam em consonância com essa realidade.

description: O artigo problematiza a experiência piloto da implantação do Programa Um Computador por Aluno – UCA, em escola pública da Rede Municipal de Ensino de Vitória/ES/Brasil. O objetivo foi analisar as contribuições do Programa para a formação profissional tecnológica de professores na perspectiva das subjetividades docentes, práxis pedagógica e emancipação social. A investigação de natureza qualitativa trouxe os procedimentos técnicos e científicos na “pesquisa–ação”, com sua coleta de dados pautada na observação sistemática e participante associada ao diário de campo, à aplicação de questionários e à análise de documentos oficiais. Os resultados indicaram contradições entre a utilização das Tecnologias da Informação e Comunicação – TICs, pelos docentes no cotidiano e no contexto pedagógico; constataram a fragilidade do suporte tecnológico disponibilizado; apontaram que a mudança dos meios requer mudança de concepções e que as práticas de linguagens precisam ser repensadas. Verificou-se que a formação continuada de professores é uma prioridade e que as subjetividades são transformadas neste processo, fortalecendo os objetivos emancipadores da escola.

description: Nascent soot particles with mobility diameters ≤10 nm were measured in an ethylene/air premixed flame to shed light on the challenges and potential artifacts affecting studies on soot inception by differential mobility analysis (DMA) techniques. The size distribution functions (SDFs) of particles with charge acquired either naturally or diffusively upon ion seeding were measured at several positions in the flame using rapid-dilution probing and a high-resolution DMA for different values of the ratio of dilution ratio to residence time (DR/Δt). The SDFs are roughly bimodal with a sub-3 nm mode and a larger one that appears either downstream in the flame or for low DR/Δts. Soot nuclei smaller than 3 nm preferentially acquire positive charge, which brings into question the assumption of steady-state charging probability of flame sampled soot nuclei in the bipolar diffusion neutralizer. The approximately polarity-symmetric lognormal SDF of larger particles is attributed to nuclei coagulation. Naturally charged particles increase in number when lowering DR/Δt, suggesting either their collisional charging by flame chemi-ions or particle nucleation by condensation of neutral molecules on ions or both. The critical conditions for suppressing particle coagulation and charge redistribution in the sampling system were not achieved under most conditions, despite the fact that values of DR/Δts were more favorable to such a suppression in the present experiment as compared to other studies in the literature. As a result, the identification of this “asymptotic” regime, which is critical to determine the parent SDFs and the charge state of nascent soot in the flame, is still elusive. © 2016 American Association for Aerosol Research

description: Objetivo deste trabalho foi analisar o letramento, especifi camente leitura e interpretação, dos alunos ingressantes no curso de Recursos Humanos da Universidade do Extremo Sul Catarinense (UNESC). Os pressupostos teóricos revisados foram sobre: letramento - Soares (2001), Kleiman (1995), e letramento acadêmico – Fischer (2008) e Oliveira (2009). Quanto ao método, trata-se de pesquisa qualitativa e descritiva que teve como corpus 26 acadêmicos do curso de Recursos Humanos. Para avaliar as competências de leitura dos acadêmicos foram preparadas e aplicadas atividades com base na matriz de Língua Portuguesa para o 3º ano do Ensino Médio do INEP (Instituto Nacional de Estudos e Pesquisas Educacionais). A referida matriz é composta por tópicos que descrevem quais habilidades dos alunos devem ser medidas e avaliadas pelo professor. Os resultados desse estudo mostraram que, apesar de não se ter um critério que possa defi nir um indivíduo como letrado ou iletrado na literatura, os alunos responderam adequadamente 70% das questões solicitadas cujo foco era leitura e interpretação.

description: During occupational exposure studies, the use of conventional scanning mobility particle sizers (SMPS) provides high quality data but may convey transport and application limitations. New instruments aiming to overcome these limitations are being currently developed. The purpose of the present study was to compare the performance of the novel portable NanoScan SMPS TSI 3910 with that of two stationary SMPS instruments and one ultrafine condensation particle counter (UCPC) in a controlled atmosphere and for different particle types and concentrations. The results show that NanoScan tends to overestimate particle number concentrations with regard to the UCPC, particularly for agglomerated particles (ZnO, spark generated soot and diesel soot particles) with relative differences >20%. The best agreements between the internal reference values and measured number concentrations were obtained when measuring compact and spherical particles (NaCl and DEHS particles). With regard to particle diameter (modal size), results from NanoScan were comparable < [± 20%] to those measured by SMPSs for most of the aerosols measured. The findings of this study show that mobility particle sizers using unipolar and bipolar charging may be affected differently by particle size, morphologies, particle composition and concentration. While the sizing accuracy of the NanoScan SMPS was mostly within ±25%, it may miscount total particle number concentration by more than 50% (especially for agglomerated particles), thus making it unsuitable for occupational exposure assessments where high degree of accuracy is required (e.g., in tier 3). However, can be a useful instrument to obtain an estimate of the aerosol size distribution in indoor and workplace air, e.g., in tier 2.

description: This study aims to discuss the concept of cultural sustainability and its relation to architecture and urbanism. We asked a fundamental question: what conditions can create a sense of cultural sustainability in a contemporary and future Muslim city? And how can the contemporary and future Muslim city demonstrate the value of culture in the built environment? We illustrated the value of culture in the old Muslim cities; in particular, we selected the Eminönü neighborhood in al-Fatih district in Istanbul, Turkey, as an example that achieved cultural sustainability. We read the history and the morphology of the Eminönü neighborhood that is still sustained and alive until today. In addition, to expand the understanding of cultural sustainability and urbanism, we studied the meaning of cultural sustainability, the evolution of culture in sustainable development, and its relation to the built environment. Furthermore, we discussed how scholars and researchers have explained and studied the concept of cultural sustainability in the built environment from different perspectives. In this regard, we suggested a theoretical framework that includes three roles: cultural sustainability “in” buildings, cultural sustainability “for” buildings, and cultural sustainability “as” buildings to analyze the built environment in the Eminönü neighborhood. Three main areas in the Eminönü neighborhood were analyzed through the framework’s criteria and indicators we have suggested. In conclusion, we aim to argue the possibility of considering the cultural aspect of a city as a separate component in the sustainability model and to emphasize the important role of culture in creating the city’s image and identity through architecture. Also, to offer a cultural sustainability framework that can be adopted to be applied in any neighborhood.

Usando como modelo teórico o Enfoque Ontossemiótico do conhecimento e do ensino da matemática, analisaram-se os conflitos matemáticos implícitos nas respostas dos alunos, assim como os objetos e processos matemáticos utilizados, para caracterizar os possíveis conflitos semióticos que conduziram a respostas incorretas. Em termos de resultados, para além da elevada percentagem de alunos que não responderam às questões salienta-se a existência de vários conflitos semióticos associados à formulação das hipóteses e ao cálculo da probabilidade do erro tipo I.

Year: 2019

description: Partimos da constatação de que o sucesso escolar é claramente dependente da competência de escrita demonstrada em vários géneros escolarizados. Assim, a escrita escolar, com as suas legítimas exigências, expõe a desigualdade dos alunos; contudo, pensamos ser possível, na escola, abordar a competência de escrita de uma forma mais global, que integre a relação pessoal com o saber e com a escrita, desenvolvida em contextos escolares, mas também extraescolares. Tal abordagem didática poderá abrir caminho para a reconstrução de uma relação mais positiva com as práticas escriturais escolares, que seja consequente – como se pretende – nos conhecimentos de escrita e em textos mais conformes às normas da escrita escolar. Argumentamos, portanto, a favor da entrada da “relação com a escrita” nos dispositivos didáticos e descrevemos modos de operacionalização inscritos numa oficina sobre a escrita, vocacionada para conhecer e intervir na relação com a escrita que adolescentes do 7.º ano estavam a desenvolver. A partir de alguns exemplos de atividades e de reflexões dos alunos, salientamos os principais resultados, indícios de mudanças favoráveis na relação dos Sujeitos com a escrita, e procuramos deixar pistas de formas como a escola e o professor de língua podem transformar a escrita escolar em instrumento de inclusão e de construção e não de segregação e de reprodução, por via da reflexão e da partilha quer dos processos quer dos produtos textuais afiliados a contextos escolares, pessoais e sociais.

description: A infeção por VIH/Sida, um dos mais graves problemas de saúde pública do mundo, afeta atualmente cerca de 35 milhões de pessoas, apesar dos progressivos sinais animadores no sentido de a contrariar, como a diminuição do número de mortes provocadas pelo VIH/Sida, o aumento do acesso ao tratamento, entre outros (UNAIDS, 2014). As campanhas de prevenção da infeção VIH/Sida, uma peça chave na resposta à epidemia, tanto pelo apoio às iniciativas de prevenção como na promoção de um ambiente livre de estigmas e discriminação, veiculam com frequência representações de género múltiplas e conflituantes (Meyer, Santos, Oliveira & Wilhelms, 2004), baseadas em estereótipos de papéis sexuais e de género (OPS, 2010). À luz de uma tão proclamada educação em sexualidade, que permita a aprendizagem de informações culturalmente relevantes e cientificamente corretas (UNESCO, 2010), é possível incorporar a análise crítica destes discursos, que “nunca dizem nada por dizer” (Gregolin, 2007, p.23) e que, impregnados de desigualdades de género (e poder), obstaculizam a prevenção (Pinto-Coelho, 2009; Rogow & Haberland, 2005). Este artigo, inserido no Projeto de Doutoramento em curso, onde se analisam campanhas de prevenção do VIH/Sida produzidas por OG e ONG de Países da CPLP entre 2000 e 2010, procura ser mais um contributo para o debate.

description: Quando a promoção da colaboração está na ordem do dia, as ferramentas disponibilizadas gratuitamente pela web social, como os fóruns de discussão online, surgem como pontos de encontro entre indivíduos que desejam trabalhar juntos para alcançar finalidades comuns. Na formação inicial de professores, como noutros cursos de Ensino Superior, esta tem vindo a ser uma prática em crescimento e de sucesso. Partindo desta realidade, desenvolveu-se um estudo de caso numa turma de um curso de mestrado profissionalizante na Universidade de Aveiro. Nele participaram dois grupos de estudantes, tendo-se recolhido dados nos anos letivos de 2010/2011 e 2011/2012. Pretendia-se: i) identificar as suas representações sobre trabalho colaborativo (através de um questionário e uma reflexão escrita individual), ii) compreender a influência dessas representações na adoção de práticas colaborativas num fórum de discussão online (através de um questionário e registos no fórum), iii) compreender o contributo da colaboração adotada num fórum de discussão online para a construção de conhecimento didático sobre a abordagem da ortografia (através dos registos no fórum e dos instrumentos didáticos produzidos pelos grupos) e iv) compreender o contributo desse conhecimento para a conceção de instrumentos didáticos sobre a abordagem da ortografia (através dos registos no fórum e dos instrumentos didáticos produzidos). Os resultados revelaram uma relação entre a (des)valorização da colaboração e a sua adoção num ambiente colaborativo, como o fórum de discussão online, com repercussões no conhecimento construído, logo nos instrumentos didáticos concebidos pelos estudantes. No presente artigo, pretendemos discutir estes resultados.

description: O presente estudo teve como principal objetivo perceber o contributo do uso da técnica Synectics no desenvolvimento do potencial criativo de estudantes do ensino superior universitário, num contexto de sala de aula. Assumindo uma natureza mista, pretende captar os dados, partindo das perceções dos próprios intervenientes no estudo de caso. Assim, esta investigação envolve o estudo intensivo e detalhado de um pequeno grupo, formado por estudantes a frequentar o Mestrado em Comunicação Multimédia, na Universidade de Aveiro, em Portugal. Recorre a escalas de medida específicas, entre as quais o Teste Pensando Criativamente de Torrance e um Teste de Diagnóstico, desenvolvido na unidade curricular de Criatividade na Comunicação Multimédia, para se poder cumprir com os objetivos definidos neste estudo. Conclui-se, pelos dados coligidos e pela respetiva análise, que a aplicação do Synectics não só ajudou os estudantes a desenvolverem o seu potencial criativo, como também os ajudou a melhor reconhecerem o seu perfil criativo, tendo contribuído para desenvolver a flexibilidade, a originalidade e a fluência das suas respostas, e, simultaneamente, desenvolver e incentivar o pensamento divergente.

Satisfação docente e discente nos regimes presencial e a distância: estudo comparativo no contexto do Ensino Superior Politécnico
Creators: name: Chagas, Laura

Publisher: name: Indagatio Didactica
Year: 2019

description: Este artigo incide sobre a temática da satisfação dos estudantes e docentes do ensino superior, numa perspetiva comparativa da análise entre os regimes presencial e a distância. Através de um estudo de matriz quantitativa, de teor descritivo-correlacional, procura-se saber (i) quais os elementos que mais contribuem para a satisfação discente em ambos regimes e quais as diferenças encontradas nos dois, (ii) que fatores mais significativamente concorrem para a satisfação docente e que diferenças se registam entre as duas metodologias e (iii) de que modo se correlaciona a satisfação de estudantes e docentes. Os resultados encontrados evidenciam índices favoráveis de satisfação discente nos dois regimes, não se assinalando diferenças significativas entre os mesmos. As dimensões em que se verificaram índices mais elevados de satisfação global foram, no regime presencial, ‘infraestruturas tecnológicas’ e ‘corpo docente e tutores e, no regime a distância, ‘conteúdos’ e ‘serviços de apoio’. Por sua vez, o índice de satisfação mais reduzido recaiu sobre a dimensão ‘sistema de avaliação’, em ambos os regimes. Os docentes experienciam níveis moderados de satisfação, sobretudo em associação à subescala ‘instrutor’. Crê-se que as diversas Instituições de Ensino Superior que têm implementado iniciativas de Ensino a Distância podem beneficiar das sugestões veiculadas nas conclusões do estudo, as quais se pretende que contribuam para o aperfeiçoamento da oferta de cursos desta modalidade no contexto português.

description: Objective: We examined the physician perspectives on asthma management in Asia. Methods: An online/face-to-face, questionnaire-based survey of respiratory specialists and primary care physicians from eight Asian countries/region was carried out. The survey explored asthma control, inhaler selection, technique and use; physician-patient communications and asthma education. Inclusion criteria were >50% of practice time spent on direct patient care; and treated ≥30 patients with asthma per month, of which >60% were aged ≥12 years. Results: REALISE Asia (Phase 2) involved 375 physicians with average 15.9(±6.8) years of clinical experience. 89.1% of physicians reporting use of guidelines estimated that 53.2% of their patients have well-controlled (GINA-defined) asthma. Top consideration for inhaler choice was asthma severity (82.4%) and lowest, socio-economic status (32.5%). 54.7% of physicians checked their patients’ inhaler techniques during consultations but 28.2(±19.1)% of patients were using their inhalers incorrectly. 21.1-57.9% of physicians could spot improper inhaler techniques in video demonstrations. 79.6% of physicians believed combination inhalers could increase adherence because of convenience (53.7%), efficacy (52.7%) and usability (18.9%). Initial and follow-up consultations took 16.8(±8.4) and 9.2(±5.3) minutes respectively. Most (85.1%) physicians used verbal conversations and least (24.5%), video demonstrations of inhaler use. 56.8% agreed that patient attitudes influenced their treatment approach. Conclusion: Physicians and patients have different views of ‘well-controlled’ asthma. While physicians informed patients about asthma and inhaler usage, they overestimated actual usage and patients’ knowledge was sub-optimal. Physician-patient interactions can be augmented with understanding of patient attitudes, visual aids and ancillary support to perform physical demonstrations to improve treatment outcomes.

description: This Thesis looks at investors’ loss tolerance with portfolios managed by a human advisor compared to an algorithm with different degrees of humanization. The main goal is to explore differences between these groups (Humanized Algorithm, Dehumanized Algorithm, Humanized Human and Dehumanized Humans) and a potential diverging effect of humanizing. The Thesis is based on prior research (Hodge et al., 2018) but incorporates new aspects such as additional variables (demographics, prior experiences) and a comparison between users and non-users of automated-investment products. The core of this research is an experiment simulating an investment portfolio over time with four different portfolio managers. Subjects were asked to decide if they want to hold or sell a declining portfolio at five points in time to measure their loss tolerance. A cox regression model shows that portfolios managed by the Humanized Human had the highest loss tolerance. Humanizing leads to higher loss tolerance for the human advisor but to lower loss tolerance for algorithmic advisors within the non-user group.

description: Der § 2b UStG setzt für die juristischen Personen des öffentlichen Rechts die Mehrwertsteuer-Systemrichtlinie in deutsches Recht um und löste die alte systemwidrige Rechtslage des § 2 Abs. 3 UStG ab. Die juristischen Personen des öffentlichen Rechts müssen daher bei jeder Leistung prüfen, ob sich der Umfang ihrer Umsatzbesteuerung geändert hat bzw. ändern wird unter dem Gesichtspunkt der Wettbewerbsverzerrung. Die Arbeit untersucht daher, welche Änderung der § 2b UStG auf die umsatzsteuerliche Behandlung von wirtschaftlichen Tätigkeiten von juristischen Personen des öffentlichen Rechts hat und wie sich diese auswirken. Die Arbeit stellt die Grundzüge der Umsatzbesteuerung, die Umsatzbesteuerung nach alter und nach neuer Rechtslage dar. Abschließend wird der Umstellungsprozess zur neuen Rechtslage dargestellt. Als Ergebnis kann festgestellt werden, dass die unternehmerische Betätigung von juristischen Personen des öffentlichen Rechts sich vergrößern wird, da jede einzelne Leistung untersucht werden muss. Hierdurch kann es zu Fehleinschätzungen bei der Leistungszuordnung kommen, was zu einer falschen Umsatzsteuerdeklaration führt. Auf der anderen Seite kann das Volumen des Vorsteuerabzuges sich erhöhen. Es bleibt abzuwarten, ob der § 2b UStG europarechtskonform ist. Keywords: Umsatzbesteuerung; juristische Person des öffentlichen Rechts; § 2b UstG; Mehrwertsteuer-Systemrichtlinie; Umstellungskonzept.

description: CELF2 is an RNA binding protein that has been implicated in developmental and signal-dependent splicing in the heart, brain and T cells. In the heart, CELF2 expression decreases during development, while in T cells CELF2 expression increases both during development and in response to antigen-induced signaling events. Although hundreds of CELF2-responsive splicing events have been identified in both heart and T cells, the way in which CELF2 functions has not been broadly investigated. Here we use CLIP-Seq to identified physical targets of CELF2 in a cultured human T cell line. By comparing the results with known functional targets of CELF2 splicing regulation from the same cell line we demonstrate a generalizable position-dependence of CELF2 activity that is consistent with previous mechanistic studies of individual CELF2 target genes in heart and brain. Strikingly, this general position-dependence is sufficient to explain the bi-directional activity of CELF2 on 2 T cell targets recently reported. Therefore, we propose that the location of CELF2 binding around an exon is a primary predictor of CELF2 function in a broad range of cellular contexts.
Hätte eine Pre-Mortem-Analyse den Tod von eLWIS verhindern können? – Verhaltensorientierte Ansätze für effektives Kostenmanagement in Großprojekten

description: Im Juni 2018 gab der Discounter Lidl bekannt, dass er das in Kooperation mit SAP durchgeführte IT-Investitionsprojekt „eLWIS“ mit sofortiger Wirkung einstellen würde. Die bis zu diesem Zeitpunkt angefallenen Kosten betrugen bereits rund 500 Mio. Euro. Damit reiht sich Lidl in eine durchaus beachtliche Liste jener Unternehmen ein, die ein geplantes IT-Großprojekt nicht im vorgesehenen Kosten- und Zeitrahmen abzuwickeln vermochten. Die enorme Verbreitung dieser Problematik über eine Vielzahl von Branchen hinweg gibt Anlass zu einer intensiven Analyse der Erfolgsfaktoren für effektives Kostenmanagement in Großprojekten. Einen vielversprechenden Ansatz stellt in diesem Kontext das verhaltensorientierte Controlling dar, das vor allem Maßnahmen gegen kognitive Fehlleistungen und Könnensdefizite der handelnden Akteure in den Mittelpunkt der Betrachtung rückt. Im Rahmen dieser Arbeit werden ausgewählte kognitive Verzerrungen dargestellt, die im Kontext von Investitionsprojekten zu dysfunktionalem Entscheidungsverhalten führen können. Darauf aufbauend sollen Lösungsmöglichkeiten dargelegt werden, mit deren Hilfe diese Verzerrungen aufgefangen und negative Konsequenzen für das Unternehmen vermieden werden können. Keywords: Investitionsprojekte; Projektcontrolling; verhaltensorientiertes Controlling; kognitive Verzerrungen.

Giving in Unilaterally Risky Dictator Games: A Model of Allocation Decisions Under Existential Threat
Creators: name: Kovatsch, Sarah Franziska
Publisher: name: Junior Management Science
Year: 2020

description: This study reports experimental results from variations of the standard dictator game that capture different variants of unilaterally risky allocation decisions where only the dictator’s payoff is subject to risk. Thereby, it addresses the question of whether decisions under existential threat, modeled as a risk to the dictator’s payoff, encourage or discourage generosity in individual decision making. It aims at bridging the gap between experimental economics and psychological research on the behavioral impact of mortality salience. Results show that giving in unilterally risky dictator games increases with the risk imposed on the dictator’s payoff. Risk aversion falls short of explaining the increase in generosity. Instead, the observed behavior is most likely motivated by a preference for efficient capital employment. Moreover, dictator games prove to be an apt model for decisions under existential threat. Keywords: dictator games; risky decisions; mortality salience; generosity; existential threat.

Stochastic Optimization of Bioreactor Control Policies Using a Markov Decision Process Model

description: Biopharmaceuticals are the fastest-growing segment of the pharmaceutical industry. Their manufacture is complicated by the uncertainty exhibited therein. Scholars have studied the planning and operation of such production systems under some uncertainties, but the simultaneous consideration of fermentation and resin yield uncertainty is lacking so-far. To study the optimal operation of biopharmaceutical production and purification systems under these uncertainties, a stochastic, dynamic approach is necessary. This thesis provides such a model by extending an existing discrete state-space, infinite horizon Markov decision process model of upstream fermentation. Tissue Plasminogen Activator fermentation and chromatography was implemented. This example was used to discuss the optimal policy for operating different fermentation setups. The average per-cycle operating profit of a serial setup was 1,272 $; the parallel setup produced negative average rewards. Managerial insights were derived from a comparison to a basic, titer maximizing policy and process sensitivities. In conclusion, the integrated stochastic optimization of biopharma production and purification control aids decision making. However, the model assumptions pose room for further studies. Keywords: Markov decision process; biopharmaceuticals production; fermentation uncertainty; chromatography resin; stochastic performance decay.

Value Co-Creation: Eine Analyse von Treibern und Gestaltungsansätzen für B2B- vs. B2C-Kunden
Creators: name: Steinhardt, Felix Konstantin
Publisher: name: Junior Management Science
Year: 2020

description: Value Co-Creation (CC) wird eine hohe Bedeutung zugesprochen, da sie ermöglicht, Kunden aktiv in die Wertschöpfung von Unternehmen einzubeziehen und so neue Produkte und Dienstleistungen zu kreieren, die optimal auf Bedürfnisse abgestimmt sind. In dieser Arbeit werden Beweggründe bzw. Treiber für die CC-Teilnahme aus Kundensicht identifiziert. Dies geschieht anhand exemplarischer Szenarien mit quantitativen Auswertungen. Hierbei wird erstmalig auf Gemeinsamkeiten und Unterschiede der Bedeutung der Treiber von CC bei business-to-business-Kunden (Geschäftskunden) vs. business-to-consumer-Kunden (Privatkunden) im direkten Vergleich eingegangen.Was bewegt die Kunden dazu, sich an anbieterinitiierten CC-Aktivitäten zu beteiligen?Wie unterscheidet sich die Bedeutung dieser Treiber für beide Kundentypen B2B vs. B2C im Detail? Bei B2B-Kunden werden hierfür zwei Betrachtungsebenen unterschieden: die organisationale, strategische Ebene des gesamten Unternehmens („firm-level“) und die individuelle Perspektive der Mitarbeiter eines Unternehmens, welches Geschäftskunde ist („individuallevel“). Zusäzlich werden praktische Gestaltungsansätze für CC diskutiert. Die Ergebnisse tragen zum tieferen CC-Verständnis bei und geben dabei Anhaltspunkte für die Initiierung von CC-Projekten. Keywords: Co-Creation; Customer Engagement; B2B-Treiber; B2C-Treiber; Kundenmanagement.

Animal Research in Neurotechnology: Wilful Ignorance, Blameworthiness, and the Virtue of Inquisitiveness

description: Neurotechnology is a developing field of brain-centred research, aimed at enabling the brain to control, modify, and simulate our environment. With broad applications, the actual and potential involvement of animals in research and development of neurotechnology is extensive, however, as an emerging field, the moral permissibility of animals in neurotechnology has been understudied. Valued as a multi-billion-dollar sector, there has been an increase in research in the area over the last decade, and with increasing research comes increasing harms to animals, due both to the number of animals used and, as the sector develops, potential novel harms. Because of these current and prospective harms to animals, my research explores our ignorance of animal suffering in invasive neurotechnology research, and investigates whether and how we may be wilfully ignorant of those harms to which we contribute. My project further explores whether we have moral responsibilities to inquire about how animals may have been involved before we accept a particular treatment.
Existing literature on blameworthiness tends to concentrate on direct actions that harm others, it is relatively silent on activities and choices that cause or propagate indirect harms to nonhuman animals. My research addresses this deficit by relying on a vice epistemology account to argue that it is entirely appropriate to attribute blameworthiness for our epistemic failings in relation to this engagement with products of animal research. My research further argues that, when moral harms do, or could, ensue from that engagement, we have an obligation to correct those failings. These arguments have the potential to lead to a deeper recognition of the implications of, and create change in, our interactions with nonhuman animals in the space of neurotechnology research specifically, and our interactions with others more generally.

description: Information and assessment tools concerning Tagalog phonological development are minimally available. The current study thus sets out to develop elicitation and analysis tools for Tagalog. A picture elicitation task was designed with a warm-up, screener and two extension lists, one with more complex and one with simpler words. A nonlinear phonological analysis form was adapted from English (Bernhardt & Stemberger, 2000) to capture key characteristics of Tagalog. The tools were piloted on a primarily Tagalog-speaking 4-year-old boy living in a Canadian-English-speaking environment. The data provided initial guidance for revision of the elicitation tool (available at phonodevelopment.sites.olt.ubc.ca). The analysis provides preliminary observations about possible expectations for primarily Tagalog-speaking 4-year-olds in English-speaking environments: Lack of mastery for tap/trill ‘r’, and minor mismatches for vowels, /l/, /h/ and word stress. Further research is required in order to develop the tool into a norm-referenced instrument for Tagalog in both monolingual and multilingual environments.
