Big Data: Wrongs and Rights by Andrew Cormack (WAIS Seminar)

Abstract: Big Data has been characterised as a great economic opportunity and a massive threat to privacy. Both may be correct: the same technology can indeed be used in ways that are highly beneficial and those that are ethically intolerable, maybe even simultaneously. Using examples of how Big Data might be used in education - normally referred to as "learning analytics" - the seminar will discuss possible ethical and legal frameworks for Big Data, and how these might guide the development of technologies, processes and policies that can deliver the benefits of Big Data without the nightmares. Speaker Biography: Andrew Cormack is Chief Regulatory Adviser, Jisc Technologies. He joined the company in 1999 as head of the JANET-CERT and EuroCERT incident response teams. In his current role he concentrates on the security, policy and regulatory issues around the network and services that Janet provides to its customer universities and colleges. Previously he worked for Cardiff University running web and email services, and for NERC's Shipboard Computer Group. He has degrees in Mathematics, Humanities and Law.

On lions, impala, and bigraphs: modelling interactions in Ubiquitous Computing

As ubiquitous systems have moved out of the lab and into the world the need to think more systematically about how there are realised has grown. This talk will present intradisciplinary work I have been engaged in with other computing colleagues on how we might develop more formal models and understanding of ubiquitous computing systems. The formal modelling of computing systems has proved valuable in areas as diverse as reliability, security and robustness. However, the emergence of ubiquitous computing raises new challenges for formal modelling due to their contextual nature and dependence on unreliable sensing systems. In this work we undertook an exploration of modelling an example ubiquitous system called the Savannah game using the approach of bigraphical rewriting systems. This required an unusual intra-disciplinary dialogue between formal computing and human- computer interaction researchers to model systematically four perspectives on Savannah: computational, physical, human and technical. Each perspective in turn drew upon a range of different modelling traditions. For example, the human perspective built upon previous work on proxemics, which uses physical distance as a means to understand interaction. In this talk I hope to show how our model explains observed inconsistencies in Savannah and ex- tend it to resolve these. I will then reflect on the need for intradisciplinary work of this form and the importance of the bigraph diagrammatic form to support this form of engagement.

Big Data or Right Data?

Abstract Big data nowadays is a fashionable topic, independently of what people mean when they use this term. But being big is just a matter of volume, although there is no clear agreement in the size threshold. On the other hand, it is easy to capture large amounts of data using a brute force approach. So the real goal should not be big data but to ask ourselves, for a given problem, what is the right data and how much of it is needed. For some problems this would imply big data, but for the majority of the problems much less data will and is needed. In this talk we explore the trade-offs involved and the main problems that come with big data using the Web as case study: scalability, redundancy, bias, noise, spam, and privacy.

The Open Web of Things as a means to unlock the potential of the IoT

Abstract: There is a lot of hype around the Internet of Things along with talk about 100 billion devices within 10 years time. The promise of innovative new services and efficiency savings is fueling interest in a wide range of potential applications across many sectors including smart homes, healthcare, smart grids, smart cities, retail, and smart industry. However, the current reality is one of fragmentation and data silos. W3C is seeking to fix that by exposing IoT platforms through the Web with shared semantics and data formats as the basis for interoperability. This talk will address the abstractions needed to move from a Web of pages to a Web of things, and introduce the work that is being done on standards and on open source projects for a new breed of Web servers on microcontrollers to cloud based server farms. Speaker Biography -Dave Raggett : Dave has been involved at the heart of web standards since 1992, and part of the W3C Team since 1995. As well as working on standards, he likes to dabble with software, and more recently with IoT hardware. He has participated in a wide range of European research projects on behalf of W3C/ERCIM. He currently focuses on Web payments, and realising the potential for the Web of Things as an evolution from the Web of pages. Dave has a doctorate from the University of Oxford. He is a visiting professor at the University of the West of England, and lives in the UK in a small town near to Bath.

Bias in the Social Web

Abstract A frequent assumption in Social Media is that its open nature leads to a representative view of the world. In this talk we want to consider bias occurring in the Social Web. We will consider a case study of liquid feedback, a direct democracy platform of the German pirate party as well as models of (non-)discriminating systems. As a conclusion of this talk we stipulate the need of Social Media systems to bias their working according to social norms and to publish the bias they introduce. Speaker Biography: Prof Steffen Staab Steffen studied in Erlangen (Germany), Philadelphia (USA) and Freiburg (Germany) computer science and computational linguistics. Afterwards he worked as researcher at Uni. Stuttgart/Fraunhofer and Univ. Karlsruhe, before he became professor in Koblenz (Germany). Since March 2015 he also holds a chair for Web and Computer Science at Univ. of Southampton sharing his time between here and Koblenz. In his research career he has managed to avoid almost all good advice that he now gives to his team members. Such advise includes focusing on research (vs. company) or concentrating on only one or two research areas (vs. considering ontologies, semantic web, social web, data engineering, text mining, peer-to-peer, multimedia, HCI, services, software modelling and programming and some more). Though, actually, improving how we understand and use text and data is a good common denominator for a lot of Steffen's professional activities.

Data-Driven Text Generation using Neural Networks & Provenance is Complicated and Boring — Is there a solution?

Title: Data-Driven Text Generation using Neural Networks Speaker: Pavlos Vougiouklis, University of Southampton Abstract: Recent work on neural networks shows their great potential at tackling a wide variety of Natural Language Processing (NLP) tasks. This talk will focus on the Natural Language Generation (NLG) problem and, more specifically, on the extend to which neural network language models could be employed for context-sensitive and data-driven text generation. In addition, a neural network architecture for response generation in social media along with the training methods that enable it to capture contextual information and effectively participate in public conversations will be discussed. Speaker Bio: Pavlos Vougiouklis obtained his 5-year Diploma in Electrical and Computer Engineering from the Aristotle University of Thessaloniki in 2013. He was awarded an MSc degree in Software Engineering from the University of Southampton in 2014. In 2015, he joined the Web and Internet Science (WAIS) research group of the University of Southampton and he is currently working towards the acquisition of his PhD degree in the field of Neural Network Approaches for Natural Language Processing. Title: Provenance is Complicated and Boring — Is there a solution? Speaker: Darren Richardson, University of Southampton Abstract: Paper trails, auditing, and accountability — arguably not the sexiest terms in computer science. But then you discover that you've possibly been eating horse-meat, and the importance of provenance becomes almost palpable. Having accepted that we should be creating provenance-enabled systems, the challenge of then communicating that provenance to casual users is not trivial: users should not have to have a detailed working knowledge of your system, and they certainly shouldn't be expected to understand the data model. So how, then, do you give users an insight into the provenance, without having to build a bespoke system for each and every different provenance installation? Speaker Bio: Darren is a final year Computer Science PhD student. He completed his undergraduate degree in Electronic Engineering at Southampton in 2012.

Evaluación de la pertinencia de los criterios que miden los estándares de habilitación para IPSSO propuestos por el Ministerio de la Protección Social

Se estudió la pertinencia de los criterios, calificación y modo de verificación de los estándares de calidad para IPSSO del “Manual de procedimientos para verificar si las instituciones prestadoras de salud ocupacional, cumplen con los estándares mínimos del sistema de garantía de la calidad en salud ocupacional y riesgos profesionales (SGC-SORP)”, con el objetivo de identificar las fortalezas y posibles ajustes mediante una revisión sistemática y análisis teórico de los estándares de calidad, logrando obtener un conocimiento específico y profundo sobre el modo como funcionaba el instrumento, mediante los cuales se logró sintetizar aquellos aspectos ideales teóricamente para la prestación con calidad del servicio de salud ocupacional, en función de los requerimientos establecidos en la normatividad, concluyendo que quizás es más conveniente crear un instrumento específico para salud ocupacional, higiene y seguridad industrial y aplicar el manual de habilitación actual para el cumplimiento obligatorio de estándares de calidad, que deben cumplir todo tipo de IPS en general sin diferenciar el tipo de especialidad.

Se estudiaron 60 pacientes, que ingresaron al azar a la Fundación Oftalmológica Nacional, con diagnóstico clínico de neoplasia de superficie ocular o lesión sospechosa de neoplasia, quienes fueron sometidos a citología de impresión y posterior resección quirúrgica completa, más estudio patológico de la lesión. Se realizó un análisis descriptivo, analizando la sensibilidad y la especificidad con el método clásico y análisis bayesiano.

Lo ambiental y lo social de la aspersión en Colombia. ¿Política ambiental o estrategia antinarcóticos?

En este artículo se revisan y analizan algunos aspectos del Programa de Erradicación de Cultivos Ilícitos con Glifosato (PECIG) y su Plan de Manejo Ambiental, con el ánimo de demostrar que no consideran de manera adecuada los componentes ambiental y social. Desde la perspectiva de las políticas públicas se demuestra que se ajustan más a una estrategia militar-antinarcóticos que social y medioambiental, contrario al querer transmitido en la definición del instrumento, que habla de la compensación, prevención y mitigación de impactos, la protección de los recursos naturales, del medio ambiente y de la salud de la ciudadanía ubicada en las zonas de influencia directa. Para ello, se hace un recuento de cómo está definido el Programa y los organismos que lo componen; después se explica el Plan de Manejo Ambiental y el análisis de su implementación, posteriormente se muestran los resultados obtenidos de esta verificación para, finalmente, formular las respectivas conclusiones.-----This paper reviews and analyzes issues of the Illicit Crop Eradication Program with Glyphosate (ICEPG) and its Environmental Management Plan, with the aim to demonstrate that the environmental and social components have not been properly considered. From the public policy viewpoint, they are shown to fit more into a military antinarcotics strategy rather than a social and environmental strategy, as opposed to the aims contained in the instrument definition, which talks about impact compensation, prevention, and mitigation; and protection of natural resources, environment, and population’s health within the direct influence areas. For this purpose, an initial review of the Program definition and component organizations is provided; the Environmental Management Plan is explained, its implementation is analyzed; the results from this verification are shown; and, finally, the respective conclusions are formulated.

Occupational therapy and its relevance in social projects. relationships, learning and opportunities: collection of experiences of University of Alberta Mscot students in Bogotá, Colombia

Occupational therapists are equipped to promote wellbeing through occupation and to enable participation and meaningful engagement of people in their social and physical environments (WFOT, 2012). As such, the role of the occupational therapists is profoundly linked to the social, cultural and environmental characteristics of the contexts in which occupations take place. The central role that context plays in occupational performance creates an interesting dichotomy for the occupational therapist: on one hand, a profound understanding of cultural and social factors is required from the Occupational Therapy (OT) in order to develop a meaningful and successful collaboration with the person; on the other hand, the ability of the occupational therapists to recognize and explore the contextual factor of an occupation-person dyad transcends cultural and spatial barriers. As a result, occupational therapists are equipped to engage in international collaboration and practice, and as such face unique and enriching challenges. International fieldwork experiences have become a tool through which occupational therapists in training can develop the critical skills for understanding the impact of cultural and social factors on occupation. An OT student in an international fieldwork experience faces numerous challenges in leading a process that is both relevant and respectful to the characteristics of the local context: language, cultural perceptions of occupation and personhood, religious backgrounds, health care access, etc. These challenges stand out as ethical considerations that must be considered when navigating an international fieldwork experience (AOTA, 2009). For more than five years now, the Faculty of Rehabilitation Medicine (FRM) of the University of Alberta (UoFA) and the School of Medicine and Health Sciences at the Universidad del Rosario (UR), Bogota, Colombia, have sustained a productive and meaningful international collaboration. This collaboration includes a visit by Dr. Albert Cook, professor of the FRM and former dean, to the UR as the main guest speaker in the International Congress of Technologies for Disability Support (IBERDISCAP) in 2008. Furthermore, Dr. Cook was a speaker in the research seminar of the Assistive Technology Research Group of the Universidad del Rosario. Following Dr. Cook’s visit, Professors Liliana Álvarez and Adriana Ríos travelled to Edmonton and initiated collaboration with the FRM, resulting in the signing of an agreement between the FRM and the UR in 2009, agreement that has been maintained to this day. The main goal of this agreement is to increase academic and cultural cooperation between the UR and the UofA. Other activities have included the cooperation between Dr. Kim Adams (who has largely maintained interest and effort in supporting the capacity building of the UR rehabilitation programs in coordinating the provision of research placement opportunities for UR students at the UofA), an Assistive Technology course for clinicians and students led by Dr. Adams, and a research project that researched the use of basic cell phones to provide social interaction and health information access for people with disabilities in a low-income community in Colombia (led by Tim Barlott, OT, MSc, under the supervision of Dr. Adams). Since the beginning, the occupational therapy programs of the Universidad del Rosario and the University of Alberta have promoted this collaboration and have strived to engage in interactions that provide further development opportunities for students and staff. As part of this process, the international placement experience of UofA OT students was born under the leadership of: Claudia Rozo, OT program director at UR, placement and academic leadership of Elvis Castro and Angélica Monsalve, professors of the occupational therapy program at UR; and Dr. Lili Liu, OT department director at UofA, Cori Schmitz, Academic coordinator of clinical education at the UofA; and Tim Barlott and Liliana Álvarez leading the international and cross-cultural aspect of this collaboration.This publication summarizes and illustrates the process of international placement in community settings in Colombia, undertaken by occupational therapy students of the University of Alberta. It is our hope that this document can provide and document the ethical considerations of international fieldwork experience, the special characteristics of communities and the ways in which cultural and social competences are developed and help international students navigate the international setting. We also hope that this document will stimulate discussion among professional and academic communities about the importance and richness of international placement experiences and encourage staff and students to articulate their daily efforts with the global occupational therapy agenda.

Análisis de sensibilidad para un modelo de medición de percepción de marca basado en simulación computacional por agentes

Se presenta el análisis de sensibilidad de un modelo de percepción de marca y ajuste de la inversión en marketing desarrollado en el Laboratorio de Simulación de la Universidad del Rosario. Este trabajo de grado consta de una introducción al tema de análisis de sensibilidad y su complementario el análisis de incertidumbre. Se pasa a mostrar ambos análisis usando un ejemplo simple de aplicación del modelo mediante la aplicación exhaustiva y rigurosa de los pasos descritos en la primera parte. Luego se hace una discusión de la problemática de medición de magnitudes que prueba ser el factor más complejo de la aplicación del modelo en el contexto práctico y finalmente se dan conclusiones sobre los resultados de los análisis.

Caracterización de la exposición ocupacional a los gases, dióxido de azufre (so2), sulfuro de hidrógeno (h2s), y monóxido de carbono (co), y la percepción de salud de los trabajadores, en una empresa del sector hidrocarburo en Colombia

En el proceso de extracción de petróleo (crudo) deben realizarse tratamientos físicos y químicos en estaciones de recolección del hidrocarburo con el fin de garantizar su calidad antes de su entrega para el transporte y comercialización. Para la realización de esta actividad el personal operativo requerido (operadores) debe realizar diferentes actividades, tales como ronda operacional, verificación de sistemas de almacenamiento del crudo, agua residual del proceso e insumos químicos utilizados en su tratamiento y manipulación de facilidades en las estaciones de recolección, entre otras. Como resultados de las actividades rutinarias los operadores están expuestos a factores de riesgo químico asociados a gases y vapores orgánicos generados en los procesos de tratamiento del crudo. En el presente trabajo se realizaron mediciones de calidad de aire e higiene industrial en diferentes estaciones tratamiento de crudo, con el propósito de evaluar los niveles de exposición de los operadores a gases y vapores de hidrocarburos durante el proceso de tratamiento de crudo y dar respuesta a la siguiente pregunta: ¿existe relación entre la exposición ocupacional, las emisiones atmosféricas de gases (SO2, CO, H2S) y la percepción de afectación de la salud de los trabajadores que se encuentran expuestos durante la actividad laboral, en una empresa del sector de hidrocarburos? Se realizó un estudio de corte transversal, mediante la aplicación de cuestionarios sobre las condiciones de trabajo y de salud a 30 trabajadores que laboran en una estación de tratamiento de crudo de una compañía del sector de hidrocarburos. Los operadores objeto de estudio laboran en turnos rotativos, han estado vinculados con la compañía por más de dos años y tienen contrato directo, adicionalmente, se identificaron los factores de riesgos ambientales y ocupacionales para el grupo de trabajadores y se realizó una revisión de los informes de medición de higiene industrial y de calidad de aire de las estaciones donde labora el personal seleccionado con el fin de establecer si los resultados se relacionan. Los resultados obtenidos indican que el 100% de los trabajadores son de género masculino y se desempeñan en cargos de operadores, recorredores de pozos de crudo y supervisores. El 97% de los operadores tiene más de cuarenta años de edad y el 80% de los mismos ha laborado por más de 6 años en la compañía. Acerca de la percepción de los trabajadores sobre su estado de salud el 90% afirma que su salud es buena, el 97% respondió que no presenta problemas respiratorios, el 23% manifiesta que presenta trastornos dermatológicos y el 27% indican que presenta dolor de cabeza constante. De la revisión de los informes de calidad de aire disponibles se encontró que las mediciones de Dióxido de Azufre SO2, Monóxido de Carbono CO se encuentran dentro del rango definido como el de menor impacto para la salud humana. De los datos del informe se puede concluir que la calidad del aire es buena en el 100% de las áreas de influencia de las estaciones de tratamiento de crudo. Según los informes de higiene industrial el 34% de las instalaciones presenta concentraciones de Sulfuro de Hidrógeno (H2S) en el límite permisible para exposiciones crónicas en un promedio ponderado de tiempo (TLV-TWA) y el límite permisible para exposiciones agudas en un límite de exposición a corto plazo (TLV-STEL). Solo el 37% de los trabajadores objeto de este estudio percibe el riesgo por la exposición a factores de riesgo químicos y son claramente consientes que se encuentran expuestos a estos riesgos por la manipulación de productos químicos y exposición a sustancias químicas producto de sus actividades rutinarias, el 73% no percibe el riesgo de exposición por su actividad laboral. Se recomienda que la compañía fortalezca su esquema de vigilancia para generar alternativas que eleven los niveles de consciencia del riesgo del trabajador. Los factores de riesgo ambiental y ocupacional, de los gases y vapores generados se deben al proceso de tratamiento de crudo, están mutuamente relacionados dado que al generarse una emisión y/o escape no controlado como consecuencia se tiene una afectación directa al medio ambiente y a los trabajadores.

Verificación de los niveles de atenuación de dos tipos de protectores auditivos tipo copa en trabajadores de una empresa del sector Hidrocarburos. Barrancabermeja-Colombia 2013.

El presente estudio se realizó con el fin de verificar los niveles de atenuación de dos tipos de protectores auditivos tipo copa, bajo condiciones reales de operación en una empresa del sector hidrocarburos en Colombia. Esta verificación se llevó a cabo determinando las diferencias existentes entre los niveles de atenuación establecidos por el fabricante (NRR Teórico), los niveles de atenuación ajustados de acuerdo a la metodología propuesta por NIOSH (NRR Ajustado) y los niveles de atenuación obtenidos experimentalmente (NRR Experimental). El estudio se desarrolló sobre la evaluación de los niveles equivalentes de presión sonora, mediante dosimetrías de doble canal, valorando los niveles de ruido al interior y al exterior del pabellón auditivo de forma simultánea. Los valores obtenidos en las mediciones se ajustaron a los criterios establecidos en la norma ISO 11904 parte 1 considerando la estimación de niveles de inmisión sonora mediante técnica MIRE (Microphone In a Real Ear) corregidos a condiciones de campo libre. Los resultados obtenidos permitieron establecer diferencias significativas entre los niveles de atenuación teóricos, ajustados y experimentales, aspecto que brinda oportunidades de mejora cuando se trata de seleccionar y mantener elementos de protección personal auditiva como estrategia preventiva primaria en el propósito de la disminución de la probabilidad de ocurrencia de hipoacusia neurosensorial inducida por ruido en el lugar de trabajo.

Caracterizacion de nódulos tiroideos: concordancia entre estudio citopatologico y ecografia en la detección de nódulos malignos

: Los métodos imagenológicos para evaluar los nódulos tiroideos han sido motivo de estudio en las últimas décadas, especialmente la ecografía sobresale sobre las otras modalidades diagnósticas por su accesibilidad, portabilidad, y seguridad. A pesar de ello, las características ecográficas de cada nódulo han sido objeto de controversia en cuanto a su potencial detección de malignidad o benignidad. Se presenta un estudio de concordancia entre el estudio citopatológico y la ecografía para la caracterización nódulos tiroideos de naturaleza maligna y benigna, y su análisis de pruebas diagnósticas. Metodología: Se realizó un estudio descriptivo de concordancia con estudio de pruebas diagnósticas anidado. Se escogieron todos los pacientes con nódulos tiroideos a quienes se les realizó ecografía y estudio citopatológico de la lesión y se estudiaron los hallazgos ecográficos para evaluar su potencial diagnóstico para malignidad. Se incluyeron un total de 100 pacientes con nódulos tiroideos potencialmente malignos. La concordancia entre la ecografía en modo B y el estudio citopatológico fue moderada (índice kappa 0.55). La característica con mayor potencial para detectar malignidad fue la presencia de Microcalcificaciones (sensibilidad 75%, especificidad 92%).
