Theory and Practice: A Matter of Words. Language, Knowledge and Professional Community in Social Work

The relation between theory and practice in social work has always been controversial. Recently, many have underlined how language is crucial in order to capture how knowledge is used in practice. This article introduces a language perspective to the issue, rooted in the ‘strong programme’ in the sociology of knowledge and in Wittgenstein’s late work. According to this perspective, the meaning of categories and concepts corresponds to the use that concrete actors make of them as a result of on-going negotiation processes in specific contexts. Meanings may vary dramatically across social groups moved by different interests and holding different cultures. Accordingly, we may reformulate the issue of theory and practice in terms of the connections between different language games and power relationship between segments of the professional community. In this view, the point is anyway to look at how theoretical language relates to practitioners’ broader frames, and how it is transformed while providing words for making sense of experience.

A simplified model for evaluation of fatigue damage in frames

Many studies have been developed to analyze the structural seismic behavior through the damage index concept. The evaluation of this index has been employed to quantify the safety of new and existing structures and, also, to establish a framework for seismic retrofitting decision making of structures. Most proposed models are based in a posterthquake evaluation in such a way they uncouple the structural response from the damage evaluation. In this paper, a generalization of the model by Flórez-López (1995) is proposed. The formulation employs irreversible thermodynamics and internal state variable theory applied to the study of beams and frames and it allows and explicit coupling between the degradation and the structural mechanical behavior. A damage index es defined in order to model elastoplasticity coupled with damage and fatigue damage.

Redes de información y conocimiento climatológico en el mundo hispánico del siglo XVIII

Durante la Ilustración, el imperio español alcanzó su máxima amplitud y las instituciones oficiales incrementaron su apoyo a las ciencias. Para defender sus fronteras y ejercer con eficacia el poder político, económico y religioso, la Corona y la Iglesia necesitaban obtener información precisa --incluida la climatológica-- de las posesiones españolas y de los pobladores de éstas. Fueron varios los procedimientos empleados para ello: sistema de cuestionarios y relaciones geográficas, estudios medico-topográficos, visitas e inspecciones oficiales, expediciones político-científicas, correspondencia epistolar, artículos periodísticos, etc. Dichos procedimientos fueron aplicados por redes de informadores cuyas actuaciones se basaban en la división del trabajo, el reparto de colaboradores en diferentes lugares, el uso de códigos de comunicación comprensibles, el envío de los resultados a los superiores jerárquicos y la toma de decisiones por las autoridades competentes. Las redes de información estaban sometidas a dictámenes que normalizaban su creación y continuidad temporal, daban forma a su estructura interna, especificaban sus cometidos y obligaban a cumplir protocolos y plazos. En su seno se idearon planes de investigación integrados en el estudio general de la Tierra, el ser humano y la cultura. El beneficio de las actuaciones de sus miembros se plasmó en cubrir grandes ámbitos geográficos con el consiguiente ahorro de tiempo, esfuerzos y medios. En sus correspondientes contextos, los miembros de las redes efectuaron estudios climatológicos conforme a intereses, imposiciones y circunstancias específicas. Así, los médicos se interesaron por las condiciones climáticas que influían en la salud humana; los funcionarios reales y los ingenieros militares describieron los climas locales y regionales aptos para el fomento y el control político, jurídico y educativo de los habitantes de los territorios hispánicos; los expedicionarios estudiaron las interacciones entre los fenómenos naturales y las influencias de los accidentes geográficos en los climas; los clérigos se interesaron por los aspectos estéticos, apologéticos y contemplativos de los climas; finalmente, en la prensa de la época se publicaron registros meteorológicos periódicos y trabajos climatológicos varios. En definitiva, el saber climatológico en el mundo hispánico ilustrado aportó algunos rasgos esenciales a la climatología en una etapa pre-fundacional de esta disciplina. Dichos rasgos se desarrollaron generalmente en una escala local o regional y se refirieron a los siguientes asuntos: el calor como principal agente de las modificaciones atmosféricas, de la formación de vapor acuoso y de las precipitaciones; la influencia del suelo en el aumento de humedad y calor en el aire; el poder de los vientos para trasladar de un lugar a otro el frío o el calor, el vapor de agua, los fenómenos atmosféricos y los agentes responsables de las enfermedades contagiosas; las propiedades del aire atmosférico y su capacidad para interaccionar con el medio ambiente; la condición estática y repetitiva de los climas, si bien se admitió que dichos fenómenos podían sufrir modificaciones; la corroboración experimental de las diferencias climáticas entre las zonas tropicales y medias del planeta; la refutación de que la naturaleza americana y sus habitantes eran inferiores a los europeos; y la demostración de que los principios rectores de los fenómenos físicos del Viejo y el Nuevo Mundo eran idénticos. Desde el último tercio del siglo XVIII, los documentos producidos por los componentes de las redes de información incluyeron datos meteorológicos. Pero no siempre se emplearon los mismos instrumentos de medida ni se siguieron los mismos protocolos de indagación en idénticas condiciones. Además, y salvo excepciones, los períodos durante los cuales se recabaron datos atmosféricos fueron relativamente cortos, y los expertos no efectuaron las mismas operaciones aritméticas con los parámetros. Por esta razón, y por la orientación utilitaria de los ilustrados hispánicos, el saber climatológico no obtuvo en el período y en el ámbito geográfico considerados resultados teóricos apreciables; en cambio, dio lugar a una gran cantidad de actividades prácticas con aplicaciones a la medicina, la agricultura, la náutica, el fomento, la prevención de riesgos naturales, etc. La principal utilidad de este trabajo consiste en servir de complemento a los procedimientos actualmente en uso en historia de la hidrología y en climatología histórica. ABSTRACT During the Enlightenment, the Spanish Empire achieved its highest length and State institutions increased their support to sciences. In order to defend their frontiers and to exercise political, economical and religious power, the Crown and the Church needed exact information --including the climatologic one-- about its possessions and its habitants. Some of the procedures employed to get that objective were: system of questionnaires and geographic relations, medical-topographic studies, official visits and inspections, political-scientific expeditions, direct mail, journalistic articles, etc. Those procedures were applied by informers´ networks which obtained, manned and transmitted every kind of data about the natural and moral reality of the Hispanic territories; their actions were based on the division of tasks, the distribution of collaborators at several places, the use of understandable communication codes and the sending of results to the hierarchical superiors; after, the competent authorities took decisions. The information networks were subjected to rules witch regulated its creation, temporary continuity, interior structure, objectives, protocols and periods. Their memberships invented plans about the general research of the Earth, the human beings and the culture; and they contributed to get benefits because of covering large geographic frames and economizing time, effort and means. According to their specifics contexts, concerns, impositions and circumstances, the informers performed climatologic tasks. Thus, the physicians were interested in the climatic conditions which affected to human health; the royal officers and military engineers described the most propitious climates to patronage and political, lawful and educative control of inhabitants of Hispanic territories; the participants in politic-scientific expeditions studied the interactions among natural phenomena and the influence of geographic aspects on the climate; the clergymen underlined the esthetic, apologetic and contemplative face of climates; finally, in the newspapers were published a lot of meteorological data and climatologic works. So, the climatologic knowledge in the Hispanic enlightened world added these essential aspects --referred in a local and regional area-- during the pre-foundational epoch of the climatology: the heat as first agent of atmospheric modifications, aqueous vapor and precipitations; the influx of the land in the increment of humidity and heat of the air; the power of the winds to convey the cold, the heat, the aqueous vapor, the atmospheric phenomena and the agents which caused contagious maladies; the properties of the air and its faculty to mediate with the environs; the static and repetitive condition of the climate and its possibility to experience change; the experimental confirmation of climatic varieties between tropical and central areas of the planet; the negation of the inferiority of the American nature and inhabitants; the demonstration about the equality of the rules which conducted physical phenomena in the Old and the New world. Since the last third part of the eighteenth century, the documents produced by the members of the networks included meteorological data. But the informers were not used to employ the same measure instruments and homogeneous protocols completion in the same conditions. Exceptions besides, the times of taking atmospheric data, usually were very short; and the experts did not carry out the same arithmetical operations with parameters. Because of this reason and the utilitarian guidance of the informers, during the Hispanic Enlightenment, it was not possible to obtain theoretic conclusions about climatologic knowledge; but there were a lot of practical activities applied to Medicine, Agriculture, Navigation, patronage, prevention of natural risks, etc. The main utility of this work consist in favoring the present procedures of the History of Hydrology and Historic Climatology.

Numerical analysis of shell and spatial structures

Since the advent of the computer into the engineering field, the application of the numerical methods to the solution of engineering problems has grown very rapidly. Among the different computer methods of structural analysis the Finite Element (FEM) has been predominantly used. Shells and space structures are very attractive and have been constructed to solve a large variety of functional problems (roofs, industrial building, aqueducts, reservoirs, footings etc). In this type of structures aesthetics, structural efficiency and concept play a very important role. This class of structures can be divided into three main groups, namely continuous (concrete) shells, space frames and tension (fabric, pneumatic, cable etc )structures. In the following only the current applications of the FEM to the analysis of continuous shell structures will be discussed. However, some of the comments on this class of shells can be also applied to some extend to the others, but obviously specific computational problems will be restricted to the continuous shells. Different aspects, such as, the type of elements,input-output computational techniques etc, of the analysis of shells by the FEM will be described below. Clearly, the improvements and developments occurring in general for the FEM since its first appearance in the fifties have had a significative impact on the particular class of structures under discussion.

[Estimates from Walton & Moore for the raising and altering of seats in the anatomical room, and for repairing the lower room, northwest corner of the College House], 2 December 1806

The estimate includes projected costs for the materials and labor required for each renovation. The anatomical room needed its circular seats raised and altered. The renovation of the lower room included making new window frames and sashes (including replacing glass), installing new doors, and repairing the floors.

The future imagined: Exploring fiction as a means of reflecting on today’s Grand Societal Challenges and tomorrow’s options

European science policy (so-called Horizon 2020) is guided by Grand Societal Challenges (GSCs) with the explicit aim of shaping the future. In this paper we propose an innovative approach to the analysis and critique of Europe’s GSCs. The aim is to explore how speculative and creative fiction offer ways of embodying, telling, imagining, and symbolising ‘futures’, that can provide alternative frames and understandings to enrich the grand challenges of the 21st century, and the related rationale and agendas for ERA and H2020. We identify six ways in which filmic and literary representations can be considered creative foresight methods (i.e. through: creative input, detail, warning, reflection, critique, involvement) and can provide alternative perspectives on these central challenges, and warning signals for the science policy they inform. The inquiry involved the selection of 64 novels and movies engaging with notions of the future, produced over the last 150 years. Content analysis based on a standardised matrix of major themes and sub-domains, allows to build a hierarchy of themes and to identify major patterns of long-lasting concerns about humanity’s future. The study highlights how fiction sees oppression, inequality and a range of ethical issues linked to human and nature’s dignity as central to, and inseparable from innovation, technology and science. It concludes identifying warning signals in four major domains, arguing that these signals are compelling, and ought to be heard, not least because elements of such future have already escaped the imaginary world to make part of today’s experience. It identifies areas poorly defined or absent from Europe's science agenda, and argues for the need to increase research into human, social, political and cultural processes involved in techno-science endeavours.

Rehabilitation approaches to promote successful unilateral and bilateral fittings and avoid inappropriate prescription

Successful hearing aid fitting occurs when the person fitted wears the aid/s on a regular basis and reports benefit when the aid/s is used. A significant number of people fitted with unilateral or bilateral hearing aids for the first time do not continue to use one or both aids in the long term. In this paper, factors consistently found in previous research to be associated with unsuccessful fitting are explored; in particular, the negative attitudes of some clients towards hearing aids, their lack of motivation for seeking help, inability to identify goals for rehabilitation, and problems with the management of the devices. It is argued here that success in hearing aid fitting involves the same dynamics as found with other assistive technologies (e.g., wheelchairs, walking frames), and is dependent on a match between the characteristics of a prospective user, the technology itself, and the environments of use (Scherer, 2002). It is recommended that for clients who identify concerns about hearing aids, or who are unsure about when they would use them, and/or are likely to have problems with aid management, only one aid be fitted in the first instance, if hearing aid fitting is to proceed at all. Rehabilitation approaches to promote successful fitting are discussed in light of results obtained from a survey of clients who experienced both successful and unsuccessful aid fitting.

Institutions, policies, and arguments:context and strategy in EU policy framing

Studies of framing in the EU political system are still a rarity and they suffer from a lack of systematic empirical analysis. Addressing this gap, we ask if institutional and policy contexts intertwined with the strategic side of framing can explain the number and types of frames employed by different stakeholders. We use a computer-assisted manual content analysis and develop a fourfold typology of frames to study the frames that were prevalent in the debates on four EU policy proposals within financial market regulation and environmental policy at the EU level and in Germany, Sweden, the Netherlands and the United Kingdom. The main empirical finding is that both contexts and strategies exert a significant impact on the number and types of frames in EU policy debates. In conceptual terms, the article contributes to developing more fine-grained tools for studying frames and their underlying dimensions.

Framing infectious diseases and U.S. public opinion

The United States has been increasingly concerned with the transnational threat posed by infectious diseases. Effective policy implementation to contain the spread of these diseases requires active engagement and support of the American public. To influence American public opinion and enlist support for related domestic and foreign policies, both domestic agencies and international organizations have framed infectious diseases as security threats, human rights disasters, economic risks, and as medical dangers. This study investigates whether American attitudes and opinions about infectious diseases are influenced by how the issue is framed. It also asks which issue frame has been most influential in shaping public opinion about global infectious diseases when people are exposed to multiple frames. The impact of media frames on public perception of infectious diseases is examined through content analysis of newspaper reports. Stories on SARS, avian flu, and HIV/AIDS were sampled from coverage in The New York Times and The Washington Post between 1999 and 2007. Surveys of public opinion on infectious diseases in the same time period were also drawn from databases like Health Poll Search and iPoll. Statistical analysis tests the relationship between media framing of diseases and changes in public opinion. Results indicate that no one frame was persuasive across all diseases. The economic frame had a significant effect on public opinion about SARS, as did the biomedical frame in the case of avian flu. Both the security and human rights frames affected opinion and increased public support for policies intended to prevent or treat HIV/AIDS. The findings also address the debate on the role and importance of domestic public opinion as a factor in domestic and foreign policy decisions of governments in an increasingly interconnected world. The public is able to make reasonable evaluations of the frames and the domestic and foreign policy issues emphasized in the frames.

Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review

Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the development of information technology, the use of technology in social work practice has risen dramatically. The aim of this literature review is to map out the state of the art of knowledge about the usage of ICT in elderly care and to figure out research-based knowledge about the usability of ICT for the prevention of loneliness and social isolation of elderly people. The data for the current research comes from the core collection of the Web of Science and the data searching was performed using Boolean? The searching resulted in 216 published English articles. After going through the topics and abstracts, 34 articles were selected for the data analysis that is based on a multi approach framework. The analysis of the research approach is categorized according to some aspects of using ICT by older adults from the adoption of ICT to the impact of usage, and the social services for them. This literature review focused on the function of communication by excluding the applications that mainly relate to physical nursing. The results show that the so-called ‘digital divide’ still exists, but the older adults have the willingness to learn and utilise ICT in daily life, especially for communication. The data shows that the usage of ICT can prevent the loneliness and social isolation of older adults, and they are eager for technical support in using ICT. The results of data analysis on theoretical frames and concepts show that this research field applies different theoretical frames from various scientific fields, while a social work approach is lacking. However, a synergic frame of applied theories will be suggested from the perspective of social work.

Theory and language of climate change communication

Climate change communication has become a salient topic in science and society. It has grown to be something like a booming industry alongside more established ‘communication enterprises’, such as health communication, risk communication, and science communication. This article situates the theory of climate change communication within theoretical developments in the field of science communication. It discusses the importance and difficulties inherent in talking about climate change to different types of publics using various types of communication tools and strategies. It engages with the difficult issue of the relationship between climate change communication and behavior change, and it focuses, in particular, on the role of language (metaphors, words, strategies, frames, and narratives) in conveying climate change issues to stakeholders. In the process, it attempts to provide an overview of emerging theories of climate change communication, theories that recently have begun to proliferate quite dramatically. In some cases, we can, therefore only provide signposts to the most relevant research that is being carried out with regard to climate change communication without being able to engage with all its aspects. We end with an assessment of how communication could be improved in light of the theories and practices discussed in this article.

ViDRILO: The Visual and Depth Robot Indoor Localization with Objects information dataset

In this article we describe a semantic localization dataset for indoor environments named ViDRILO. The dataset provides five sequences of frames acquired with a mobile robot in two similar office buildings under different lighting conditions. Each frame consists of a point cloud representation of the scene and a perspective image. The frames in the dataset are annotated with the semantic category of the scene, but also with the presence or absence of a list of predefined objects appearing in the scene. In addition to the frames and annotations, the dataset is distributed with a set of tools for its use in both place classification and object recognition tasks. The large number of labeled frames in conjunction with the annotation scheme make this dataset different from existing ones. The ViDRILO dataset is released for use as a benchmark for different problems such as multimodal place classification and object recognition, 3D reconstruction or point cloud data compression.

Thermoregulatory response in hair sheep and shorn wool sheep

This study’s main goal was to evaluate the thermoregulatory responses velocity through the variation of rectal temperature (RT), related to the thermolytic pathways, respiratory rate (RR) and sweating rate (SR) among different sheep breeds. Ninety female sheep, eighteen of each breed: Santa Ines and Morada Nova (Brazilian hair breeds), Texel, Suffolk and Ile de France (wool breeds) were challenged during three non-consecutive summer days (22◦42′S, 47◦18′W, and 570m of altitude, maximum air temperature of 33.5◦C, average relative humidity of 52±6.9%). The physiological variables were registered at 0800h (T1), 1300 h (T2: after 2 h of shade rest), 1400 h (T3) (after one hour of sun exposure) and in the shade at 1415 h (T4), 1430 h (T5), 1445 h (T6) and 1500 h (T7) and a thermotolerance index (TCI) was calculated as (10-(T7 to T4)-T1). The statistical analysis was performed by a mathematical model including the fixed effects of breeds and time frames, and the interaction between these effects, besides random effects such as animal and day. The Santa Ines breed presented the lowest RT after sun exposure (39.3 ± 0.12 ◦ C; P < 0.05) and it was the only one to recover morning RT 60 min after heat stress (38.7 and 38.9 for 1300 h and 1500 h; P > 0.05). Hair breeds presented RR lower (P < 0.05) than wool breeds. Although thick wool or hair thickness differs among and within hair and wool breeds (P < 0.05), SR did not differ among breeds and time (227.7 ± 16.44 g m−2 h−1 ; P > 0.05). The thermotolerance index did not differ among breeds, but it showed similar response (P > 0.05) 45 min or 1 h of shade after sun exposure. One week post shearing is not enough to wool breeds present to show thermotolerance similar to hair breeds.
