A box in the field: modernity and the barn in twentieth-century Ireland

This paper argues that the modern barn in Ireland is a complex social and architectural phenomena that is without, or has yet to find, a satisfactory discourse. Emerging in the middle third of the twentieth century, the modern barn – replete with corrugated iron and I-sections – continues to represent a presence in the Irish landscape whose ubiquity is as emphatic as its flexibility. It is, however, its universal properties that begin to suggest connections with wider narratives. The modernising aspects of the barn that appear in the 1920s and 30s begin to conflate with a rhetoric of architectural modernism which was simultaneously appearing across Europe. But while the relationship between high modernism’s critique of what it divined as the inspirational qualities of utilitarian buildings – Walter Gropius on grain silos, Le Corbusier on aircraft hangers etc. – has been well-documented, in Ireland this relationship perhaps contains another layer of complexity.
The barn’s consolidation as a modern type coincided with the search for a nation’s cultural identity after centuries of colonial rule. This tended to be an introspective vision that prioritised rural space over urban space, agriculture over industry, and imagined the small farm as a central tenet in the construction of a new State. This paper suggests that the twentieth-century barn – as a product of the mechanisation of agriculture promoted by the new administrations – is an iconic structure, emblematic of attempts to reconcile the contradictory forces and imagery of modernity with the mores of a traditional society. Moreover, given a cultural purview that was often ambivalent or even hostile to the ideologies and forms of modernity, the barn in Ireland is, perhaps, not so much the inspiration but the realisation of an architectural modernism in that country at its most pervasive, enduring and unself-conscious.

De triomf van de tiran: Triumphi als kritiekmiddel in Romeinse literatuur

Of all the rituals of ancient Rome none was more spectacular than the triumph. Scholarly attention has long been devoted to the origins and circumstances of this ritual, but lately the role of the triumph in moral discourse has also come into focus. Emperors could gain great military prestige from celebrating a triumphus, yet this prestige could (posthumously) be undermined by hostile historians and biographers who used descriptions of triumphal processions to cast unpopular emperors in a negative light. Discussing in particular the ‘bad triumphs’ of Nero, Elagabalus, and Gallienus, but also considering many other cases, this article explores how triumphal descriptions could be employed as literary weapons. Ancient authors did not hesitate to emphasize, distort, or invent certain aspects of the ritual to suit their purposes. In fact, the triumphal idiom proved such a powerful tool for the delegitimation of emperors that it was even employed to situations which did not constitute triumphal celebrations at all. Hence the cultural elite sought to control the meaning of the ritual and to establish whether emperors counted as benign rulers or tyrants.

Men’s depression and suicide literacy: A nationally representative Canadian survey

Background: Male suicide prevention strategies include diagnosis and effective management of men’s depression. Fundamental to suicide prevention efforts is public awareness, which in turn, is influenced by literacy levels about men’s depression and suicide.

Aim: To examine sex differences in mental health literacy with respect to men’s depression and suicide among a cohort of Canadian respondents.

Methods: 901 English-speaking Canadian men and women completed online survey questionnaires to evaluate mental health literacy levels using 10-item D-Lit and 8-item LOSS questionnaires, which assess factual knowledge concerning men’s depression and suicide. Statistical tests (chi-square, z-test) were used to identify significant differences between sex sub-groups at 95% confidence.

Results: Overall, respondents correctly identified 67% of questions measuring literacy levels about male depression. Respondents’ male suicide literacy was significantly poorer at 53.7%. Misperceptions were especially evident in terms of differentiating men’s depressive symptoms from other mental illnesses,
estimating prevalence and identifying factors linked to male suicide. Significant sex differences highlighted that females had higher literacy levels than men in regard to male depression.

Conclusions: Implementing gender sensitive and specific programs to target and advance literacy levels about men’s depression may be key to ultimately reducing depression and suicide among men in Canada.

Colagens têxteis: em busca de um design sustentável

Os desafios dos designers nos dias de hoje são inúmeros, sendo um deles o de desenvolver produtos que atendam ao mercado sem deixar de lado as preocupações com a sustentabilidade, seja ambiental, sócio-ética ou econômica. Assim sendo, a própria disputa para alcançar novos patamares de destaque no mercado também fez proliferar novas tecnologias de produção sustentável como um fator diferenciador nos dias de hoje que, para além de preservar a natureza, conquista uma larga faixa de clientes sensíveis a este tipo de preocupações. É objetivo deste trabalho a criação de produtos de design de moda e decoração e sua verificação enquanto design sustentável. Neste contexto, enquadra-se este trabalho que visa desenvolver produtos de moda e decoração realizados com a técnica da colagem têxtil, resultando assim, em produtos inovadores, únicos, intemporais e com design. A presente investigação desenvolveu-se em parceria com o Banco de Vestuário de Caxias do Sul, que forneceu dados para o estudo do setor têxtil e levantamento dos resíduos da indústria têxtil da região para caracterização do setor, além de disponibilizar os resíduos têxteis que serviram de base para a criação de produtos de moda e de decoração mais sustentáveis. Para a criação das superfícies têxteis coladas foram desenvolvidas amostras com testes de temperaturas e tempos para verificar a combinação que mais se adequa a cada tipo de matéria-prima. Além de fazer uso destes resíduos, a investigação contou com o auxílio de mão-de-obra de artesãs que, por sua vez, foram capacitadas com a técnica da colagem têxtil através de dois workshops. Após esta etapa, para fazer a análise dos níveis de sustentabilidade dos produtos, utilizou-se o Sustainability Design Orienting Toolkit (SDO) que é um conjunto de ferramentas que visa a orientação dos designers no desenvolvimento de produtos em termos de sustentabilidade ambiental, sócio-ética e econômica.

O perfil em homicídios múltiplos: o caso do estripador de Lisboa

Um dos objectivos deste trabalho, sobre homicídios múltiplos e o “estripador de Lisboa”, passa por sublinhar a importância dos perfis criminais e abordar os problemas de validade científica dos mesmos, tendo em conta as principais metodologias de investigação criminal e do criminal profiling, atento o valor dos processos de análise de dados que podem ser utilizados para a obtenção de informação de natureza preditiva, com relevância para os contributos da psicologia. Assim, e de um ponto de vista transdisciplinar, definimos o nosso problema de investigação questionando se os conhecimentos e competências da psicologia teriam aumentado a eficácia e a eficiência da investigação criminal relativamente ao “estripador de Lisboa”, em termos preditivos do crime e de elaboração do perfil. Para fundamentar o estudo empírico, analisamos os conceitos de violência e de perigosidade, as teorias explicativas do comportamento criminal, as características das personalidades desviantes, o conceito de psicopatia, de assassinos em série, bem como os métodos científicos e não científicos de perfis criminais. A propósito destes, salientamos o perfil lust murder. Trata-se de um estudo de casos múltiplos, complementado por uma entrevista semi-estruturada e um sistema de criminal profiling (tipo indutivo e dedutivo). A amostra é constituída por cinco mulheres, prostitutas, vítimas de homicídio, encontradas na margem Norte e na margem Sul do Tejo, cujas idades variavam entre 22 e 27 anos. Para a realização do estudo recorremos a fontes documentais, à realização da citada entrevista semi-estruturada gravada, bem como utilizámos uma máquina fotográfica e um manequim, de material acrílico, como simulacro do sexo feminino. Para cada caso foi feita uma análise qualitativa, no âmbito da metodologia de estudo de caso. Para a comparação dos casos efectuámos uma Análise de Correspondências Múltiplas (ACM). Analisados os dados, concluímos que o caso particular do “estripador de Lisboa” é, sem dúvida, um bom exemplo de que a fórmula “organizado / desorganizado” não funciona quando aplicada a casos reais. Contudo, cruzando os contributos da psicologia com a reconstituição dos factos, encontramos evidências que nos levam a classificar o autor dos crimes como um sujeito psicopata, com traços esquizóides. O assassino em série que atormentou a cidade de Lisboa seria um indivíduo aparentemente normal, com uma vida social pouco activa e uma visão hostil do mundo exterior. Seria um sujeito impulsivo e agressivo, sem capacidade para sentir qualquer empatia. Essencialmente vingativo e virado para si próprio, tenderia a desenvolver comportamentos de evitação social, mantendo os seus relacionamentos a um nível superficial. Tratar-se-ia de uma pessoa distante, centrada nele mesmo e desligada de factores externos, o que explica a sua falta de cuidado e de planeamento na cena do crime (pela não antecipação das consequências dos factores envolvidos).

Características e especificidades de jovens agressores sexuais

Nos últimos anos o estudo da violência sexual juvenil tem vindo a atrair a atenção dos serviços de saúde mental, de justiça juvenil e de políticas públicas, bem como de vários investigadores. Teoricamente existem duas perspetivas explicativas da ocorrência das agressões sexuais cometidas por adolescentes. A perspetiva generalista sugere que os crimes sexuais cometidos por jovens são mais uma manifestação de tendências delinquenciais genéricas, em que as agressões sexuais constituem apenas uma parte do comportamento antissocial do adolescente. A segunda abordagem, denominada de perspetiva especialista, entende que os jovens agressores sexuais se distinguem dos outros adolescentes agressores, argumentando que existem diferentes fatores explicativos das agressões sexuais de outras agressões delinquentes. A presente investigação, composta por cinco estudos, teve como objetivo obter resultados que pudessem contribuir para a discussão internacional sobre qual das perspetivas parece explicar de modo mais apropriado o comportamento sexualmente agressivo de jovens menores de idade. Para o efeito recorreu-se a uma amostra total de 118 adolescentes agressores sexuais (61 violadores e 57 abusadores sexuais de crianças), tendo sido efetuadas análises comparativas com 112 jovens agressores não sexuais e 98 não agressores num conjunto de dimensões (características demográficas, tipológicas, criminais, problemas de comportamento, tendências antissociais, características familiares, sociais e comunitárias e interesses sexuais). Os resultados permitiram observar algumas características diferenciadoras de jovens agressores sexuais por violação de jovens agressores sexuais de crianças. Possibilitaram, igualmente, a observação de características semelhantes entre jovens agressores sexuais e jovens agressores não sexuais, sugerindo que em algumas dimensões são, genericamente, análogas. A exceção parece centrar-se em torno das variáveis relacionadas com a sexualidade (conhecimentos e interesses sexuais atípicos). As implicações destes resultados são discutidas em torno da avaliação psicológica e da avaliação do risco de reincidência, bem como na intervenção e prevenção de comportamentos de agressão sexual juvenil.

Single and joint effects of natural and chemical stressors to the terrestrial isopod Porcellionides pruinosus

Environmental contamination and climate changes constitute two of the most serious problems affecting soil ecosystems in agricultural fields. Agriculture is nowadays a highly optimized process that strongly relies on the application of multiple pesticides to reduce losses and increase yield production. Although constituting, per se, a serious problem to soil biota, pesticide mixtures can assume an even higher relevance in a context of unfavourable environmental conditions. Surprisingly, frameworks currently established for environmental risk assessments keep not considering environmental stressors, such as temperature, soil moisture or UV radiation, as factors liable to influence the susceptibility of organisms to pesticides, or pesticide mixtures, which is raising increasing apprehension regarding their adequacy to actually estimate the risks posed by these compounds to the environment. Albeit the higher attention received on the last few years, the influence of environmental stressors on the behaviour and toxicity of chemical mixtures remains still poorly understood. Aiming to contribute for this discussion, the main goal of the present thesis was to evaluate the single and joint effects of natural stressors and pesticides to the terrestrial isopod Porcellionides pruinosus. The first approach consisted on evaluating the effects of several abiotic factors (temperature, soil moisture and UV radiation) on the performance of P. pruinosus using several endpoints: survival, feeding parameters, locomotor activity and avoidance behaviour. Results showed that these stressors might indeed affect P. pruinosus at relevant environmental conditions, thus suggesting the relevance of their consideration in ecotoxicological assays. At next, a multiple biomarker approach was used to have a closer insight into the pathways of damage of UV radiation and a broad spectrum of processes showed to be involved (i.e. oxidative stress, neurotoxicity, energy). Furthermore, UV effects showed to vary with the environment medium and growth-stage. A similar biomarker approach was employed to assess the single and joint effects of the pesticides chlorpyrifos and mancozeb to P. pruinosus. Energy-related biomarkers showed to be the most differentiating parameters since age-classes seemed to respond differently to contamination stress and to have different metabolic costs associated. Finally, the influence of temperature and soil moisture on the toxicity of pesticide mixtures was evaluated using survival and feeding parameters as endpoints. Pesticide-induced mortality was found to be oppositely affected by temperature, either in single or mixture treatments. Whereas chlorpyrifos acute toxicity was raised under higher temperatures the toxicity of mancozeb was more prominent at lower temperatures. By the opposite, soil moisture showed no effects on the pesticide-induced mortality of isopods. Contrary to survival, both temperature and soil moisture showed to interact with pesticides to influence isopods’ feeding parameters. Nonetheless, was however the most common pattern. In brief, findings reported on this thesis demonstrated why the negligence of natural stressors, or multiple stressors in general, is not a good solution for risk assessment frameworks.

Strength of visual percept generated by famous faces perceived without awareness: effects of affective valence, response latency, and visual field

Participants who were unable to detect familiarity from masked 17 ms faces ([Stone and Valentine, 2004] and [Stone and Valentine, in press-b]) did report a vague, partial visual percept. Two experiments investigated the relative strength of the visual percept generated by famous and unfamiliar faces, using masked 17 ms exposure. Each trial presented simultaneously a famous and an unfamiliar face, one face in LVF and the other in RVF. In one task, participants responded according to which of the faces generated the stronger visual percept, and in the other task, they attempted an explicit familiarity decision. The relative strength of the visual percept of the famous face compared to the unfamiliar face was moderated by response latency and participants’ attitude towards the famous person. There was also an interaction of visual field with response latency, suggesting that the right hemisphere can generate a visual percept differentiating famous from unfamiliar faces more rapidly than the left hemisphere. Participants were at chance in the explicit familiarity decision, confirming the absence of awareness of facial familiarity.

Identification of novel molecular determinants of tissue mineralization in fish

The identification of genes involved in signaling and regulatory pathways, and matrix formation is paramount to the better understanding of the complex mechanisms of bone formation and mineralization, and critical to the successful development of therapies for human skeletal disorders. To achieve this objective, in vitro cell systems derived from skeletal tissues and able to mineralize their extracellular matrix have been used to identify genes differentially expressed during mineralization and possibly new markers of bone and cartilage homeostasis. Using cell systems of fish origin and techniques such as suppression subtractive hybridization and microarray hybridization, three genes never associated with mechanisms of calcification were identified: the calcium binding protein S100-like, the short-chain dehydrogenase/reductase sdr-like and the betaine homocysteine S-methyltransferase bhmt3. Analysis of the spatial-temporal expression of these 3 genes by qPCR and in situ hybridization revealed: (1) the up-regulation of sdr-like transcript during in vitro mineralization of gilthead seabream cell lines and its specificity for calcified tissues and differentiating osteoblasts; (2) the up-regulation of S100-like and the down-regulation of bhmt3 during in vitro mineralization and the central role of both genes in cartilaginous tissues undergoing endo/perichondral mineralization in juvenile fish. While expression of S100-like and bhmt3 was restricted to calcified tissues, sdr-like transcript was also detected in soft tissues, in particular in tissues of the gastrointestinal tract. Functional analysis of gene promoters revealed the transcriptional regulation of the 3 genes by known regulators of osteoblast and chondrocyte differentiation/mineralization: RUNX2 and RAR (sdr-like), ETS1 (s100-like; bhmt3), SP1 and MEF2c (bhmt3). The evolutionary relationship of the different orthologs and paralogs identified within the scope of this work was also inferred from taxonomic and phylogenetic analyses and revealed novel protein subfamilies (S100-like and Sdr-like) and the explosive diversity of Bhmt family in particular fish groups (Neoteleostei). Altogether our results contribute with new data on SDR, S100 and BHMT proteins, evidencing for the first time the role for these three proteins in mechanisms of mineralization in fish and emphasized their potential as markers of mineralizing cartilage and bone in developing fish.

Narratives of Variation in Teacher-Pupil Relationships Across a Career

This paper reports on the findings of a research study focused on teacher perceptions of their relationships with pupils over three phases of a career. Data collected from thirty primary school teachers using a critical event narrative approach were coded and compared across the three groups of teachers at different points in their careers; 0-7 years, 8-23 years, and over 24 years. The study, based in the United Kingdom, highlighted a complex development amongst teachers which centres on five key areas identified as differentiating between the three career phases; interaction, behaviour, expectations, proximity and control. Results indicate that teachers go through a series of relationship transitions in relation to these five areas, and that these transitions can often confront teachers with conflicting views of what positive teacher-pupil relationships are and create personal dissonance as they try to make sense of their role in these relationships. Based on empirical evidence, this paper argues that positive relationships with pupils are not necessarily associated with experience and that the transitions teachers experience through their career is of concern given the centrality of teacher-pupil relationships to effective teaching.

Conceptualizing and Researching the Professionalization of Religious Education Teachers: Historical and International Perspectives

Current discussions on Religious Education (RE), both in Germany and England, focus on the quality of teaching and the professionality of teachers, but neglect the historical and institutional process of professionalization upon which conceptions of teaching quality and teacher professionality hinge. This article seeks to provide definitional clarity by differentiating between individual and collective professionalization; exploring teacher professionalization in general and in the special case of RE; and operationalizing the concept of RE teacher professionalization for the purposes of planned historical and international comparative research. A three-fold conceptualization of professionalization is proposed, consisting of the following inter-related levels: (1) initial and continuing professional development; (2) professional self-organization and professional politics; and (3) professional knowledge. The breadth, complexity and significance of the historical and institutional processes associated with the professionalization of RE teachers at each of these levels is described and discussed. It is argued that further historical and international comparative research on these lines would contribute a broader and deeper understanding of the presuppositions of RE teacher professionality beyond current debates.

Dynamic cost indexing

This paper describes the development of a generic tool for dynamic cost indexing (DCI), which encompasses the ability to manage flight delay costs on a dynamic basis, trading accelerated fuel burn against ‘cost of time’. Many airlines have significant barriers to identifying which costs should be included in ‘cost of time’ calculations and how to quantify them. The need is highlighted to integrate historical passenger delay and policy data with real-time passenger connections data. The absence of industry standards for defining and interfacing necessary tools is recognised. Delay recovery decision windows and ATC cooperation are key constraints. DCI tools could also be used in the pre-departure phase, and may offer environmental decision support functionality: which could be used as a differentiating technology required for access to designated, future ‘green’ airspace. Short-term opportunities for saving fuel and/or reducing emissions are also identified.

Phonological and articulation treatment approaches in Portuguese children with speech and language impairments: a randomized controlled intervention study

Background: In Portugal, the routine clinical practice of speech and language therapists (SLTs) in treating children with all types of speech sound disorder (SSD) continues to be articulation therapy (AT). There is limited use of phonological therapy (PT) or phonological awareness training in Portugal. Additionally, at an international level there is a focus on collecting information on and differentiating between the effectiveness of PT and AT for children with different types of phonologically based SSD, as well as on the role of phonological awareness in remediating SSD. It is important to collect more evidence for the most effective and efficient type of intervention approach for different SSDs and for these data to be collected from diverse linguistic and cultural perspectives. Aims: To evaluate the effectiveness of a PT and AT approach for treatment of 14 Portuguese children, aged 4.0–6.7 years, with a phonologically based SSD. Methods & Procedures: The children were randomly assigned to one of the two treatment approaches (seven children in each group). All children were treated by the same SLT, blind to the aims of the study, over three blocks of a total of 25 weekly sessions of intervention. Outcome measures of phonological ability (percentage of consonants correct (PCC), percentage occurrence of different phonological processes and phonetic inventory) were taken before and after intervention. A qualitative assessment of intervention effectiveness from the perspective of the parents of participants was included. Outcomes & Results: Both treatments were effective in improving the participants’ speech, with the children receiving PT showing a more significant improvement in PCC score than those receiving the AT. Children in the PT group also showed greater generalization to untreated words than those receiving AT. Parents reported both intervention approaches to be as effective in improving their children’s speech. Conclusions & Implications: The PT (combination of expressive phonological tasks, phonological awareness, listening and discrimination activities) proved to be an effective integrated method of improving phonological SSD in children. These findings provide some evidence for Portuguese SLTs to employ PT with children with phonologically based SSD
