A RBES for Generating Automatically Personalized Menus

Food bought at supermarkets in, for instance, North America or the European Union, give comprehensive information about ingredients and allergens. Meanwhile, the menus of restaurants are usually incomplete and cannot be normally completed by the waiter. This is specially important when traveling to countries with a di erent culture. A curious example is "calamares en su tinta" (squid in its own ink), a common dish in Spain. Its brief description would be "squid with boiled rice in its own (black) ink", but an ingredient of its sauce is flour, a fact very important for celiacs. There are constraints based on religious believes, due to food allergies or to illnesses, while others just derive from personal preferences. Another complicated situation arise in hospitals, where the doctors' nutritional recommendations have to be added to the patient's usual constraints. We have therefore designed and developed a Rule Based Expert System (RBES) that can address these problems. The rules derive directly from the recipes of the di fferent dishes and contain the information about the required ingredients and ways of cooking. In fact, we distinguish: ingredients and ways of cooking, intermediate products (like sauces, that aren't always made explicit) and final products (the dishes listed in the menu of the restaurant). For a certain restaurant, customer and instant, the input to the RBES are: actualized stock of ingredients and personal characteristics of that customer. The RBES then prepares a "personalized menu" using set operations and knowledge extraction (thanks to an algebraic inference engine [1]). The RBES has been implemented in the computer algebra system MapleTM2015. A rst version of this work was presented at "Applications of Computer Algebra 2015" (ACA'2015) conference.

A measure of skin familiarity and its role in the early detection of skin cancer

Skin self-examination (SSE) is promoted widely so that individuals will become familiar with their skin and be better able to identify suspicious changes earlier. However, individuals can also become familiar with their skin other than through purposeful SSE. In this article, we develop a measure of skin familiarity based on the density of spots on 14 different areas of the body. A factor analysis of the 14 body-area scores revealed that they could be grouped into four broad body regions (shoulders and back, front of legs, back of legs, and feet). Each total body score and body-region score has high internal consistency (Cronbach's alpha coefficients ranging from 0.79 to 0.93). Moreover, the scores correlate as expected with skin self-examination behaviors and other personal characteristics, indicating high construct validity. We consider the advantages that skin familiarity measures offer over the exclusive use of SSE measures in the assessment of early detection activities and discuss the direction of future research in this area

Not Getting By: Poverty Management and Homelessness in Miami

Urban inequality has emerged as one of the dominant themes of modern life and globalization. More than three million people experienced homelessness in the United States last year; in Miami-Dade, more than 15,000 individuals were homeless. Surviving extreme poverty, and exiting or avoiding homelessness, involves negotiating a complex mix of public and private assistance. However, a range of factors influence what types of help are available and how they can be accessed. Frequently, larger social structures determine which resource are available, leaving many choices entirely out of the individual’s control. For single men, who are ineligible for many benefits, homelessness can be difficult to avoid and even harder to exit. My study seeks to better understand how adult, minority men living in extreme poverty in Miami-Dade negotiate their daily survival. Specific research questions address: Do black and Hispanic men who are homeless or at risk of homelessness have different personal characteristics and different experiences in avoiding or exiting homelessness? How does Miami’s response to extreme poverty/homelessness, including availability of public benefits and public and private service organizations, either maximize or constrain the choices available to this population? And, what is the actual experience of single, adult men who are homeless or at risk of homelessness, in negotiating their daily survival? A mixed methods approach combines quantitative survey data from 7,605 homeless men, with qualitative data from 54 semi-structured interviews incorporating the visual ethnography techniques of Photo Elicitation Interviewing. Results show the differences experienced by black and Hispanic men who are poor and homeless in Miami. Findings also highlight how the community’s official and unofficial responses to homelessness intersect with the actual experiences of the persons targeted by the policies and programs, challenging preconceived notions regarding the lives of persons living in extreme poverty. It adds to the existing body of literature by focusing on the urban Miami context, emphasizing disparities amongst racial and ethnic groups. Findings are intended to provide an empirically grounded thesis that humanizes the subjects and illuminates their personal experiences, helping to inform public policy around the needs of extremely poor populations.

Niveles de actividad física en los periodos de recreo de niños y adolescentes en un colegio distrital de Bogotá

Objetivo: determinar los niveles de actividad física (AF) de niños y adolescentes entre 10 y 17 años durante los periodos de recreo escolar en un colegio distrital de Bogotá. Método: estudio de corte transversal en un colegio distrital de la localidad de Puente Aranda en Bogotá. Fueron observados a través del sistema de observación de juego y de actividad en el tiempo libre en jóvenes (SOPLAY) los niveles y tipos de AF de niños y adolescentes en los periodos de recreo durante tres semanas, utilizando una condición de observación diferente para cada semana. Adicionalmente, las condiciones del contexto de las áreas recreo deportivas fueron evaluadas. Resultados: las prevalencias de escolares sedentarios fueron de 52,4 %, 77,3 % y 64,9 % durante la 1ª, 2ª y 3ª semana respectivamente. El sexo femenino fue más sedentario con el masculino (57 %, 82 % y 73 % vs 45 %, 70 % y 54 %) para cada semana observada. Se obtuvieron diferencias significativas (p<0,05) en los niveles de AF de los escolares. Conclusión: niños y adolescentes presentan elevadas prevalencias de sedentarismo siendo las actividades más frecuentes estar sentado, de pie o acostado durante los periodos de recreo. El sexo masculino mostró porcentajes superiores de participación en AF moderadas vigorosas. Las áreas recreo deportivas no contaban con condiciones del contexto relacionadas con disponibilidad de equipamiento para realizar AF ni existencia de actividades organizadas. Son necesarios programas e intervenciones eficaces que promuevan la AF en niños y adolescentes durante el recreo de la jornada escolar.

Representaciones sociales del trasplante de médula ósea, la quimioterapia y la cirugía oncológica en población general colombiana

Las representaciones sociales son una construcción de significados que las personas otorgan a un objeto en este caso el tratamiento oncológico. En el mundo, el cáncer es una enfermedad de alta prevalencia y sus tratamientos suelen generar numerosos efectos secundarios, pero a la vez es el recurso médico disponible para controlar la enfermedad. Este estudio cualitativo tuvo como objetivo analizar las representaciones sociales del tratamiento oncológico en población colombiana. Participaron voluntariamente 20 personas seleccionadas por conveniencia. Se realizaron entrevistas abiertas y se analizaron los resultados a través del análisis temático y se interpretaron con base en la teoría de las representaciones sociales. Los resultados indicaron que las personas representan el tratamiento oncológico convencional, predominantemente como quimioterapia, generadores de sufrimiento, miedo, alto costo físico, emocional y económico; así como una apuesta en la que la ganancia puede ser la prolongación de la vida o la remisión. Se discuten los resultados y sus implicaciones.

La población estudiantil en el sétimo año de la educación pública costarricense

Seventh grade students share personal characteristics that are analyzed in this paper based on the teachers´ performance of the proper mediation for the students´ learning. The results of an investigation done with the model of teachers´ profiles at this level will be the basis for this paper (Alfaro et al, 2008a). We conclude that the biopsychosocial development and maturational stage of the transit-preteen-teen children must be the domain of faculty at this level, as well as, the socioeconomic context of family and social contexts of their students.

National university`s students perspective of teachers and college education: their characteristic and classroom environment

This article presents the results of a research project in which the characteristics of university teachers and classroom environment were studied from the students´ perspectives. The study was based on a mixed design, this one attempts to develop a profile of the teachers, with the participation of students being trained in pedagogy majors. The results indicate that the students underline the importance of personality and psico-pedagogical characteristics in contrast with the theoretical findings, which point more towards professional characteristics.

Personal indebtedness, community characteristics and theft crimes

Becker (1968) and Stigler (1970) provide the germinal works for an economic analysis of crime, and their approach has been utilised to consider the response of crime rates to a range of economic, criminal and socioeconomic factors. Until recently however this did not extend to a consideration of the role of personal indebtedness in explaining the observed pattern of crime. This paper uses the Becker (1968) and Stigler (1970) framework, and extends to a fuller consideration of the relationship between economic hardship and theft crimes in an urban setting. The increase in personal debt in the past decade has been significant, which combined with the recent global recession, has led to a spike in personal insolvencies. In the context of the recent recession it is important to understand how increases in personal indebtedness may spillover into increases in social problems like crime. This paper uses data available at the neighbourhood level for London, UK on county court judgments (CCJ's) granted against residents in that neighbourhood, this is our measure of personal indebtedness, and examines the relationship between a range of community characteristics (economic, socio-economic, etc), including the number of CCJ's granted against residents, and the observed pattern of theft crimes for three successive years using spatial econometric methods. Our results confirm that theft crimes in London follow a spatial process, that personal indebtedness is positively associated with theft crimes in London, and that the covariates we have chosen are important in explaining the spatial variation in theft crimes. We identify a number of interesting results, for instance that there is variation in the impact of covariates across crime types, and that the covariates which are important in explaining the pattern of each crime type are largely stable across the three periods considered in this analysis.

Personal branding on social media - The characteristics of strong personal brands in Finland

The purpose of the study is to define the characteristics of strong personal brands on social media in Finland. Personal branding as a phenomenon is no longer limited to celebrities and political leaders. The digital revolution and the change in online behavior have created the need for a deeper investigation of the characteristics of strong personal brands on social media. The work of different academics on personal branding are examined to gain a comprehensive understanding on this research topic that has gone through a revolution during the last decade. Early impression management theory is refined to include elements from more modern literature related to personal branding, brand identity management and social media to create a theoretical framework that simplifies the process of personal brand building on social media. The framework consisting of three phases clarifies the process of modern personal branding. The results of the study are presented in line with three research themes derived from the theoretical framework: the background of the brand, the brand identity management and the social media behavior and activities. Mixed methods are used in the research as means to broaden perception on the subject. The quantitative part of the study defines general characteristics concerning the most follower personal brands in Finland in three social media channels – Facebook, Instagram and Twitter. The other part of the research was conducted by single case study including two Finnish personal brands cases to provide a deeper understanding of personal branding practices of strong social media personal brands. The results of the study show that the most used social media channels differ in terms of the personal brand characteristics and personal branding activities. Due to the characteristics of the channels also the post activities of the personal brands differ quite significantly. It can be also inferred that there is a difference between brands with an existing offline awareness and the brands with no awareness before joining the social media. In order to reduce the gap between the ideal brand image and the current image, the brand should have a clear vision as well as a good understanding of the target group and the value it creates for its target audience. The brand identity needs to be managed by communicating with the target audience authentically in the right channels, with relevant content. The dedication, the target group’s behavior and the ability to create valuable and relevant content determines the right tactics for social media personal branding.
