Gender differences among undergraduates in the recognition of emotional facial expressions

The perceptive accuracy of university students was compared between men and women, from sciences and humanities courses, to recognize emotional facial expressions. emotional expressions have had increased interest in several areas involved with human interaction, reflecting the importance of perceptive skills in human expression of emotions for the effectiveness of communication. Two tests were taken: one was a quick exposure (0.5 s) of 12 faces with an emotional expression, followed by a neutral face. subjects had to tell if happiness, sadness, anger, fear, disgust or surprise was flashed, and each emotion was shown twice, at random. on the second test 15 faces with the combination of two emotional expressions were shown without a time limit, and the subject had to name one of the emotions of the previous list. in this study, women perceived sad expressions better while men realized more happy faces. there was no significant difference in other emotions detection like anger, fear, surprise, disgust. Students of humanities and sciences areas of both sexes, when compared, had similar capacities to perceive emotional expressions

The Agendas of The Stream

The new tech has introduced the traits of the hypermedia, interactivity and convergence in the journalism field. Moreover, it has involved the emergence of new media and changes in the informative contents. In 2006 Al Jazeera in English was created for covering the underreported regions, inasmuch as new media arise, new contents do so, thus, the research examines the agendas of The Stream, the TV show from Al Jazeera that relies heavily on social networks.

DESCRIPCIÓN Y ANÁLISIS DE LOS HALLAZGOS DE LAS INVESTIGACIONES HECHAS POR STEFAN TENGBLAD SOBRE LA PRÁCTICA DIRECTIVA HASTA EL AÑO 2014

Se realizó el análisis de ocho artículos y un libro escrito por el profesor Stefan Tengblad desde el 2000 hasta el 2012. Durante 12 años, el autor sueco se ha dado la tarea de analizar no solo los resultados obtenidos por los escritores más importantes sobre la práctica directiva, sino que también se puso en la tarea de comparar sus estudios y resultados. En las reseñas reconstructivas se pueden identificar las variables más importantes y las conclusiones que Tengblad obtuvo después de muchos años de estudio. Nuestro principal objetivo es descubrir, analizar y comprender las investigaciones hechas por el escritor sueco sobre la naturaleza de la práctica directiva hasta el año 2014. De esta manera podremos ver si las diferentes posiciones de los autores han cambiado con los años. Trataremos algunas variables importantes de la práctica directiva como el liderazgo, la fragmentación del trabajo, la comunicación escrita y electrónica, los valores, los objetivos, la toma de decisiones, las normas, la cultura corporativa, la estructura organizacional, las expectativas internas y externas, entre otras. Todo esto nos llevará a identificar a profundidad el discurso del profesor Stefan Tengblad y los aportes que le ha hecho a la comunidad no solo académica sino también laboral.

Catholic worker movement: un análisis desde la acción política no violenta y la lógica transnacional de los movimientos sociales

El Catholic Worker Movement se ha caracterizado por enmarcarse en las dinámicas de movilización social y acción política no violenta, que respondían, desde su creación en 1933, a un conjunto de problemáticas sociales y económicas sobre las cuales la sociedad civil se interesó y dio inicio a su actividad en escenarios de la política doméstica de Estados Unidos. Pese a ser un movimiento que surgió en un contexto nacional con fundamentación religiosa, el CWM alcanzó el desarrollo de lógicas transnacionales que contribuyeron a la defensa de su causa y a la reivindicación de valores y principios que motivarían posteriormente a la búsqueda de recursos para reforzar su lucha. Así, el proceso de evolución del movimiento tomó dirección en torno a fenómenos como la difusión, la adquisición de repertorios de acción colectiva correspondientes a la no violencia, y al aprovechamiento de factores exógenos y endógenos representados en distintas formas de oportunidad política y capacidad organizativa.

Fatiga Laríngea: efectos del uso prolongado de la voz

La voz como herramienta de trabajo de los docentes, puede afectarse por su uso prolongado, abuso o conductas de mal uso, que desencadenan limitaciones funcionales de origen laboral. Uno de los síntomas más frecuentes de quienes usan masivamente su voz con fines ocupacionales es la fatiga laríngea (FL), o cansancio vocal por debilitamiento muscular. El presente estudio quasiexperimental longitudinal pre- postest evaluó el efecto que el uso de la voz, analizando variables sociodemográficas, de salud y trabajo, los estilos de vida y los factores de riesgo ocupacionales, pero principalmente el efecto que produce el uso prolongado de la voz sobre las variables físico acústicas después de un día de trabajo, en 99 docentes de una institución de educación superior en Colombia, en comparación con trabajadores con menor uso vocal. Se aplicó un cuestionario de sintomatología vocal para controlar los sesgos, se le tomaron grabaciones pre y post jornada a cada trabajador con el software Speech Analizer® y se reportaron los cambios subjetivos tras un día de trabajo a cada trabajador. Fueron hallados cambios en las variables físico – acústicas como efecto del uso prolongado de la voz después de un día de trabajo en los dos grupos de participantes, en cuyo caso el efecto fue más significativo en los docentes que en los administrativos – no docentes. El riesgo de presentar trastornos de la voz se asoció directamente con la exposición a factores de riesgo ocupacionales y aquellos asociados a condiciones de salud y al estilo de vida de los individuos, cuyas consecuencias fueron mayores para el grupo de docentes; dado que al ser la voz su principal herramienta de trabajo, el uso fue mayor y asimismo la probabilidad de desencadenar sintomatología vocal, derivada de la fatiga laríngea. La variable de fo promedio para la fonación sostenida de la vocal /a/, que representa una sonido neutro en tonalidad o el tono habitual, mostró diferencias significativas entre grupos (p=0,048). Para este caso, el grupo de docentes registró un aumento de la fo en el postest en comparación con un cambio no significativo para el grupo de administrativos luego del uso prolongado de la voz. En consecuencia, hubo diferencias en el valor registrado para la máxima fo (p =0,025), mínima fo (p=0,011) y el rango de fo (p=0,012) en la emisión sostenida de la vocal /a/. Para el caso del grupo de administrativos, las diferencias significativas estuvieron dadas por la disminución de la fo, rango y máxima y mínima frecuencia en las tres vocales (/a/, /i/, /o/) en contraste con lo ocurrido para el grupo de docentes. En la intensidad de la voz fueron encontradas también diferencias significativas entre grupos (p=0,001) con un decrecimiento del volumen en el postest, tanto promedio como mínimo, máximo y rango de la intensidad, en la fonación sostenida de la vocal /a/ para el grupo de docentes; ninguna significancia estadística fue hallada en el grupo de administrativos para estas variables. Se demostró a través de mediciones objetivas y resultados verificables, el fenómeno de la fatiga laríngea, asociados a los efectos que se presentan tras la demanda vocal continua, discriminando el impacto, entre las variables de cargo y género.

La construcción narrativa de la identidad a través del conflicto y la ventrilocuación

El objetivo del siguiente trabajo es analizar el discurso de indígenas y mestizos a partir de una perspectiva pragmática. En particular, vamos a explorar la idea de que estos discursos están constituidos por muchas voces. En otras palabras, se muestra la polifonía, para utilizar una idea de Bakhtin. Según este enfoque, la identidad se desarrolla a través de la integración de voces ajenas que se produce a través de narraciones. En este sentido, la identidad surge de rellenar con la propia intención las palabras de los demás. Siguiendo la etnografía de la comunicación nuestra unidad de análisis es el acto de habla (el acto de significado) que se produce en un contexto. Sugerimos que la ventrilocuación de las ideas de otras personas y los conflictos son temas relevantes para el estudio de la construcción narrativa de la identidad.

The sight of silence : the conceptualisation of silence in the visual cultures of sign language communities

Deaf people are perceived by hearing people as living in a silent world. Yet, silence cannot exist without sound, so if sound is not heard, can there be silence? From a linguistic point of view silence is the absence of, or intermission in, communication. Silence can be communicative or noncommunicative. Thus, silence must exist in sign languages as well. Sign languages are based on visual perception and production through movement and sight. Silence must, therefore, be visually perceptible; and, if there is such a thing as visual silence, how does it look? The paper will analyse the topic of silence from a Deaf perspective. The main aspects to be explored are the perception and evaluation of acoustic noise and silence by Deaf people; the conceptualisation of silence in visual languages, such as sign languages; the qualities of visual silence; the meaning of silence as absence of communication (particularly between hearing and Deaf people); social rules for silence; and silencing strategies.

The construction of the museological object

Exhibiting is or should be to work against ignorance, especially against the most refractory of all ignorance: the pre-conceived idea of stereo typed culture. To exhibit is to take a calculated risk of disorientation - in the etymological sense: (to lose your bearings), disturbs the harmony, the evident , and the consensus, that constitutes the common place (the banal). Needless to say however it is obvious that an exhibition that deliberately tries to scandalise will create an inverted perversion which results in an obscurantist pseudo-luxury - culture ... between demagogy and provocation, one has to find visual communication's subtle itinerary. Even though an intermediary route is not so stimulating: as Gaston Bachelard said "All the roads lead to Rome, except the roads of compromise." It is becoming ever more evident that museums have undergone changes that are noticeable in numerous areas. As well as the traditional functions of collecting, conserving and exhibiting objects. museums have tried to become a means of communication, open and aware of the worries of modern society. In order to do this , it has started to utilise modern technology now available and lead by the hand of "marketing" and modern business management.

A new paradigm for BCI research

A new control paradigm for Brain Computer Interfaces (BCIs) is proposed. BCIs provide a means of communication direct from the brain to a computer that allows individuals with motor disabilities an additional channel of communication and control of their external environment. Traditional BCI control paradigms use motor imagery, frequency rhythm modification or the Event Related Potential (ERP) as a means of extracting a control signal. A new control paradigm for BCIs based on speech imagery is initially proposed. Further to this a unique system for identifying correlations between components of the EEG and target events is proposed and introduced.

Overview and response to reviewers of The Singing Neanderthals

Why are humans musical? Why do people in all cultures sing or play instruments? Why do we appear to have specialized neurological apparatus for hearing and interpreting music as distinct from other sounds? And how does our musicality relate to language and to our evolutionary history? Anthropologists and archaeologists have paid little attention to the origin of music and musicality — far less than for either language or ‘art’. While art has been seen as an index of cognitive complexity and language as an essential tool of communication, music has suffered from our perception that it is an epiphenomenal ‘leisure activity’, and archaeologically inaccessible to boot. Nothing could be further from the truth, according to Steven Mithen; music is integral to human social life, he argues, and we can investigate its ancestry with the same rich range of analyses — neurological, physiological, ethnographic, linguistic, ethological and even archaeological — which have been deployed to study language. In The Singing Neanderthals Steven Mithen poses these questions and proposes a bold hypothesis to answer them. Mithen argues that musicality is a fundamental part of being human, that this capacity is of great antiquity, and that a holistic protolanguage of musical emotive expression predates language and was an essential precursor to it. This is an argument with implications which extend far beyond the mere origins of music itself into the very motives of human origins. Any argument of such range is bound to attract discussion and critique; we here present commentaries by archaeologists Clive Gamble and Iain Morley and linguists Alison Wray and Maggie Tallerman, along with Mithen's response to them. Whether right or wrong, Mithen has raised fascinating and important issues. And it adds a great deal of charm to the time-honoured, perhaps shopworn image of the Neanderthals shambling ineffectively through the pages of Pleistocene prehistory to imagine them humming, crooning or belting out a cappella harmonies as they went.

Did they talk their way out of Africa?

Corballis suggests that fully vocal communication was invented by modern humans between 170,000 and 50,000 years ago. Because this new form of communication did not require hand gestures, he wondered whether this may have facilitated the development of lithic manufacture. I cast doubt on this interesting notion but offer an enhanced version that may have more potential.

Knowledge communication and translation- A knowledge transfer model

Purpose – The purpose of this paper is to propose a process model for knowledge transfer in using theories relating knowledge communication and knowledge translation. Design/methodology/approach – Most of what is put forward in this paper is based on a research project titled “Procurement for innovation and knowledge transfer (ProFIK)”. The project is funded by a UK government research council – The Engineering and Physical Sciences Research Council (EPSRC). The discussions are mainly grounded on a thorough review of literature accomplished as part of the research project. Findings – The process model developed in this paper has built upon the theory of knowledge transfer and the theory of communication. Knowledge transfer, per se, is not a mere transfer of knowledge. It involves different stages of knowledge transformation. Depending on the context of knowledge transfer, it can also be influenced by many factors; some positive and some negative. The developed model of knowledge transfer attempts to encapsulate all these issues in order to create a holistic framework. Originality/value of paper – An attempt has been made in the paper to combine some of the significant theories or findings relating to knowledge transfer together, making the paper an original and valuable one.

Causes of preventable drug-related hospital admissions: a qualitative study

Objective: To explore the causes of preventable drug-related admissions (PDRAs) to hospital. Design: Qualitative case studies using semi-structured interviews and medical record review; data analysed using a framework derived from Reason's model of organisational accidents and cascade analysis. Participants: 62 participants, including 18 patients, 8 informal carers, 17 general practitioners, 12 community pharmacists, 3 practice nurses and 4 other members of healthcare staff, involved in events leading up to the patients' hospital admissions. Setting: Nottingham, UK. Results: PDRAs are associated with problems at multiple stages in the medication use process, including prescribing, dispensing, administration, monitoring and help seeking. The main causes of these problems are communication failures ( between patients and healthcare professionals and different groups of healthcare professionals) and knowledge gaps ( about drugs and patients' medical and medication histories). The causes of PDRAs are similar irrespective of whether the hospital admission is associated with a prescribing, monitoring or patient adherence problem. Conclusions: The causes of PDRAs are multifaceted and complex. Technical solutions to PDRAs will need to take account of this complexity and are unlikely to be sufficient on their own. Interventions targeting the human causes of PDRAs are also necessary - for example, improving methods of communication.

Issues impairing the success of neural implant technology

By monitoring signals from the central nervous system, humans can be provided with a novel extra channel of communication that can, for example, be used for the voluntary control of peripheral devices. Meanwhile, stimulation of neural tissue can bring about sensation such as touch, can facilitate feedback from external, potentially remote devices and even opens up the possibility of new sensory input for the individual to experience. The concept of successfully harnessing and stimulating nervous system activity is though something that can only be achieved through an appropriate interface. However, interfacing the nervous system by means of implant technology carries with it many problems and dangers. Further, results achieved may not be as expected or as they at first appear. This paper describes a comparative study investigating different implant types and procedures. It is aimed at highlighting potential problem areas and is intended to provide a useful reference explaining important tolerances and limits.
