La Crisis ambiental como proceso. Un análisis reflexivo sobre su emergencia, desarrollo y profundización desde la perspectiva de la teoría crítica

La investigación se focaliza en el análisis de la crisis ambiental considerada como un fenómeno complejo de evolución incierta producto de un proceso socio histórico, cuyos orígenes se remontan a los albores del proyecto moderno y deben rastrearse en un cúmulo de circunstancias que expresan las contradicciones de un modelo socioeconómico identificado con el crecimiento sostenido de la producción y las magnitudes económicas. Partiendo de esta base, se propone abordar la relación entre saber sociológico y crisis ambiental, a partir de las contribuciones de la teoría crítica a la compresión de las causas profundas de la crisis ambiental y de sus elementos constitutivos. Para lo cual se propone profundizar en algunas categorías desarrolladas por la corriente social crítica, las cuales si bien no se refieren en forma directa a la problemática ambiental, se vislumbran como campos fértiles para comprender los procesos sociales generadores de la crisis ambiental así como las alternativas que han de adoptarse para su resolución, teniendo en cuenta los mecanismos que ejerce el sistema para neutralizar los cambios que implica la conformación de una racionalidad alternativa. Acorde con ello, la primera parte del trabajo se centra en el abordaje de la relación sociedad naturaleza en el marco de tres grandes procesos sociales identificados como cosmológico, teocéntrico y antropocéntrico, haciendo especial hincapié en la correlación que en cada una de las etapas consideradas se establece entre racionalidad dominante, producción de conocimiento y conceptualización de naturaleza. El segundo capítulo profundiza en los efectos de la racionalidad instrumental sobre la ruptura del proyecto moderno y su incidencia sobre la emergencia de la crisis ambiental, a partir de la posición adoptada por Heidegger y por los referentes de la Escuela de Frankfurt. Posteriormente el análisis se estructura en torno a las dimensiones críticas de la modernidad avanzada, considerada como contexto situacional de desarrollo y profundización de la crisis ambiental, teniendo en cuenta los aportes teóricos desarrollados por Zygmunt Bauman e Immanuel Wallerstein. Al finalizar se presentan las conclusiones generales de la tesis y las posibles líneas de investigación que se abren a partir del trabajo desarrollado.

Educação, qualificação profissional e mercado de trabalho : estudo sobre os impactos na educação da expansão econômica do complexo industrial de SUAPE/PE/Brasil

Essa pesquisa teve como preocupação central conhecer a avaliação que os estudantes do 3° ano do ensino médio da educação básica acerca da educação fornecida pela rede estadual de ensino no estado de Pernambuco quanto à preparação para o mercado de trabalho, especialmente na região do Complexo Industrial de Suape em Pernambuco, Brasil. A pesquisa contou com a participação de 130 alunos que estudavam em duas escolas do município de Ipojuca - onde se localiza o referido Complexo Industrial -, e com 07 autoridades ligadas a educação – responsáveis pelas políticas públicas nessa região e em todo estado – em Pernambuco e nas cidades do Cabo de Santo Agostinho e Ipojuca. Foram aplicados um questionário validado aos alunos e uma entrevista semi-estruturada as autoridades (secretários de estado, gerentes regionais) em educação. Na análise quantitativa fizemos uso do programa SPSS; enquanto que na análise qualitativa utilizamos a análise de discurso. A partir dos dados obtidos conseguimos como resultado que os alunos acreditam que a escola não os prepara adequadamente para o ingresso e permanência no mercado de trabalho, e acreditam ainda, que para que essa constatação possa ser modificada é preciso que haja um investimento maior na qualidade da educação como prioridade em nosso estado e em nosso país. Nesse sentido, analisamos que mesmo com todos os avanços que estão ocorrendo no Brasil, com programas e leis de incentivo a educação básica e profissional, a sociedade globalizada exige cada vez mais investimentos em educação, e que ela deixe de ser dual e torne-se integrada e onilateral, fazendo com que os alunos consigam acreditar na educação e, a partir dela se tornem sujeitos críticos e com oportunidades de ingresso no mercado com as competências que lhe são exigidas para tal fim.

Memory and power : two movements

The institutions that work with the preservation and diffusion of cultural heritage - be them archive, libraries, museums, art galleries or cultural centres - present a certain discourse about reality. To understand this discourse, composed by sound and silence, by fullness and emptiness, by presence and absence, by remembrance and forgetting, an operation is implied, not only with the enunciation of speech and its gaps, but also the comprehension of that which causes to speak, of who is speaking and of the point whence one speaks. Preservation and destruction, or, in another way, conservation and loss, walk hand in hand in the arteries of life. As suggested by Nietzsche (1999, p.273), it is impossible to live without loss, it is entirely impossible to live avoiding destruction to play its game and drive the dynamics of life on. However, by means of a kind of tautological argument, one often justifies preservation by the imminence of loss and memory by the threat of forgetting. Thus, one ceases to consider that the game and the rules of the game between forgetting and memory are not fed by themselves and that preservation and destruction are not opposed in a deadly duel, but instead they complement one another and are always at the service of subjects that build themselves and are built through social practices. To indicate that memories and forgettings can be sown and cultivated corroborates the importance of working towards the denaturalisation of these concepts and towards the understanding that they result from a construction process also involving other forces, such as: power. Power is a sower, a promoter of memories and forgettings.

Toward an acoustic vowel metric: listener validation

This paper examines objective measures of speech production, specifically vowels. The relationship between the listener's perception of sections of the vowels with their perception of the entire vocalic utterance was examined.

New Hope learning center

This paper reviews the field of speech pathology and whether it is of benefit to helping profoundly retarded children develop verbal/functional language skills.

Room-acoustic factors in attentional tracking

In a “busy” auditory environment listeners can selectively attend to one of several simultaneous messages by tracking one listener's voice characteristics. Here we ask how well other cues compete for attention with such characteristics, using variations in the spatial position of sound sources in a (virtual) seminar room. Listeners decided which of two simultaneous target words belonged in an attended “context” phrase when it was played with a simultaneous “distracter” context that had a different wording. Talker difference was in competition with a position difference, so that the target‐word chosen indicates which cue‐type the listener was tracking. The main findings are that room‐acoustic factors provide some tracking cues, whose salience increases with distance separation. This increase is more prominent in diotic conditions, indicating that these cues are largely monaural. The room‐acoustic factors might therefore be the spectral‐ and temporal‐envelope effects of reverberation on the timbre of speech. By contrast, the salience of cues associated with differences in sounds' bearings tends to decrease with distance, and these cues are more effective in dichotic conditions. In other conditions, where a distance and a bearing difference cooperate, they can completely override a talker difference at various distances.

Sudden onset stuttering in an adult: Neurogenic and psychogenic perspectives

A healthy 33 year old man with no previous history of speech language problems was referred to speech language therapy services following an episode which left him with a pronounced stutter, and which worsened over the next ten days. A range of neurological and psychological assessments failed to find any abnormality, as did MRI testing, and a diagnosis of psychogenic stuttering was made. This client was seen for three sessions of fluency therapy without significant improvement, after which he ceased attending. This paper considers the relationship between psychogenic and neurogenic stuttering generally, then more specifically in regard to this client, and the treatment he received. The paper concludes by considering problems in differentially diagnosing neurogenic from psychogenic stuttering.

The ‘thinking’ in thinking-for-speaking: where is it?

According to the thinking-for-speaking (TFS) hypothesis, speakers of different languages think differently while in the process of mentally preparing content for speech. The aim of the present paper is to critically discuss the research carried out within the TFS paradigm, against the background of the basic tenets laid out by the proponents of this framework. We will show that despite substantial progress in the investigation of crosslinguistic differences in the organisation of information in discourse, the studies that actually examine the cognitive aspects of speech production are, to date, vanishingly few. This state of affairs creates a gap in our knowledge about the thought processes that co-occur with speech production during language use and acquisition. We will argue that in order to reach a more comprehensive picture of the cognitive processes and outcomes of speech production, methodologies additional to the analysis of information organisation must be used.

Ordered-defect sulfides as thermoelectric materials

The thermoelectric behaviour of the transition-metal disulphides n-type NiCr2S4 and p-type CuCrS2 is investigated. Materials prepared by high-temperature reaction were consolidated using cold-pressing and sintering, hot-pressing (HP) in graphite dies or spark-plasma sintering (SPS) in tungsten carbide dies. The consolidation conditions have a marked influence on the electrical transport properties. In addition to the effect on sample density, altering the consolidation conditions results in changes to the sample composition, including the formation of impurity phases. Maximum room-temperature power factors are 0.18 mW m-1 K-2 and 0.09 mW m-1 K-2 for NiCr2S4 and CuCrS2, respectively. Thermal conductivities of ca. 1.4 and 1.2 W m-1 K-1 lead to figures of merit of 0.024 and 0.023 for NiCr2S4 and CuCrS2, respectively.

Effective interventions: 25 years outside the mainstream

25 years ago when the Durham conferences were in full swing, I presented results of investigations on language and behaviour in autism. I tentatively proposed that early language in autism might tell us about the cognitive skills of people with ASD and the behaviour might lead to greater understanding of which brain systems might be affected. In this presentation, I will update these topics and present a summary of other work I have been involved with in attempting to improve the lives of people with autism and their families. Data on three people with autism at the early stages of speech development showed an unusual pattern of learning colour and number names early. One possibility was that this skill represented a sign of weak central coherence – they only attended to one dimension. Colleagues of mine were equally puzzled so we tried to find out if my results could be replicated – they were not (see Schafer, Williams & Smith, 2014). Instead we found this pattern was also seen in Down Syndrome, but that early vocabulary in autism was associated with low Colorado Meaningfulness at least in comprehension. The Colorado Meaningfulness of a word is a measure of how many words can be associated with it and often involve extensive use of context. Our data suggest that the number of contexts in which a particular word can appear has a role in determining vocabulary in ASD which is consistent with the weak central coherence theory of autism. In the course of this work I also came across a group of young people with autism who appeared to have a written vocabulary but not a spoken one. It seems possible that print might be a medium of communication when speech is not. Repetitive behaviour in autism remains a mystery. We can use functional analysis to determine why the behaviour occurs, but a worryingly large percentage of behaviours are described as being internally driven or sensory reinforced. What does that mean in terms of brain activity – could it be system analogous to epilepsy, where brain activity becomes inappropriately synchronised? At the moment I cannot claim to have solved this problem, but if sensation is a driver then sensory interventions should make a difference. Data from a recent study will be presented to suggest that for some individuals this is the case. Social behaviour remains the key however, and it remains to be seen whether it is possible for social behaviour to be aided. One route that has potential is direct teaching of skills through drama and working with others who do not have social difficulties of the same type. The picture is complicated by changes in social skills with age and experience, but the failure of people with ASD to interact when in settings of social contact is little researched.
