Learning in later life: participation in formal, non-formal and informal activities in a nationally representative Spanish sample

This article examines the participation of Spanish older people in formal, non-formal and informal learning activities and presents a profile of participants in each kind of learning activity. We used data from a nationally representative sample of Spanish people between 60 and 75 years old (n = 4,703). The data were extracted from the 2007 Encuesta sobre la Participación de la Población Adulta en Actividades de Aprendizaje (EADA, Survey on Adult Population Involvement in Learning Activities). Overall, only 22.8 % of the sample participated in a learning activity. However, there was wide variation in the participation rates for the different types of activity. Informal activities were far more common than formal ones. Multivariate logistic regression indicated that education level and involvement in social and cultural activities were associated with likelihood of participating, regardless of the type of learning activity. When these variables were taken into account, age did not predict decreasing participation, at least in non-formal and informal activities. Implications for further research, future trends and policies to promote older adult education are discussed.

Is the wage curve formal or informal? Evidence for Colombia

The objective of this paper is to analyse the existente or not of a wage curve in Colombia, paying special attention to the differences between formal and informal workers, an issue that has been systematically ignored in the wage curve literature. The obtained results using microdata from the Colombian Continuous Household Survey (CHS) between 2002 and 2006 show the existence of a wage curve with a negative slope for the Colombian economy. Using information on metropolitan areas, the estimates of the elasticity of individual wages to local unemployment rates was -0.07, a value that is very close to those obtained for other countries. However, the disaggregation of statistical information for formal and informal workers has shown significant differences among both groups of workers. In particular, for the less protected groups of the labour market, informal workers (both men and women), a high negatively sloped wage curve was found. This result is consistent with the conclusions from efficiency wage theoretical models and should be taken into account when analysing the functioning of regional labour markets in developing countries.

The paper also analyzes the transformation that will have to take place in the formal surroundings of education in order to improve their social function. The main points of view and contributions made by diverse authors are discussed. It is important that all actors involved in the educational process take in consideration these contributions in order to be ready for future changes.

Estudi sobre el perfil de persones grans amb dependència del servei d'ajuda a domicili del Consell Comarcal d'Osona i el tipus de suport formal i informal

The aim of this study is to determine the profile of dependent elderly people users of the home care services (SAD) of the regional council in Osona (Consell Comarcal d´Osona) , and the characteristics of formal and informal types of support they use. Methodology. An observational study of a transversal format has been carried out, with retrospective and descriptive purposes. The target population is 63 people (26 men and 37 women) included in the program of the regional SAD They have a recognized dependence grade approved by the law 39 /2006, December 14th , promoting the individual autonomy and care of elderly people in a dependent situation. The data were collected by social workers of basic social services, first with a home visit and followed by handed out questionnaires, specifically designed for this study, in order to obtain information on socio-demographic characteristics, and the type of support formal and informal. The obtained results on the SAD users are women in a 58.7% and a 41.3 % are men. The 84% of the total sampling are 80 years old and more, being the average age of 85.2 years old. 45% of them are married, 41% are widows and widowers and 14% are single. 54% are rated with severe dependence (grade II), 42.8% with high dependence (grade III). 86% live accompanied. 100% have an informal caregiver and a 95% of the times, the caregiver is a relative who in 73% of the cases the dedication time is permanent. The coverage of the SAD has an average of 4.27 hours per week and per user. The formal services most used are the technical (62%), also the assessment of an occupational therapist at home (57%) and the telecare service in a (56%). Conclusions. The SAD is used primarily for women in an advanced age and severe dependence. The informal assistance structures have an informal caregiver, being a member of the family mostly, living with the dependent, and mainly in a permanent dedication basis. The SAD has a varied intensity in each case. The formal support services complementary to the SAD, are largely used in all cases.

Formal Power Analysis of Systems-on-Chip

The design methods and languages targeted to modern System-on-Chip designs are facing tremendous pressure of the ever-increasing complexity, power, and speed requirements. To estimate any of these three metrics, there is a trade-off between accuracy and abstraction level of detail in which a system under design is analyzed. The more detailed the description, the more accurate the simulation will be, but, on the other hand, the more time consuming it will be. Moreover, a designer wants to make decisions as early as possible in the design flow to avoid costly design backtracking. To answer the challenges posed upon System-on-chip designs, this thesis introduces a formal, power aware framework, its development methods, and methods to constraint and analyze power consumption of the system under design. This thesis discusses on power analysis of synchronous and asynchronous systems not forgetting the communication aspects of these systems. The presented framework is built upon the Timed Action System formalism, which offer an environment to analyze and constraint the functional and temporal behavior of the system at high abstraction level. Furthermore, due to the complexity of System-on-Chip designs, the possibility to abstract unnecessary implementation details at higher abstraction levels is an essential part of the introduced design framework. With the encapsulation and abstraction techniques incorporated with the procedure based communication allows a designer to use the presented power aware framework in modeling these large scale systems. The introduced techniques also enable one to subdivide the development of communication and computation into own tasks. This property is taken into account in the power analysis part as well. Furthermore, the presented framework is developed in a way that it can be used throughout the design project. In other words, a designer is able to model and analyze systems from an abstract specification down to an implementable specification.

Percepciones de distintos agentes sociales acerca de la educación formal de los chicos y chicas tutelados

This article examines the education of children and young people in public care and the available data about their situation from several conceptual perspectives.We present a qualitative empirical study on how a sample of care leavers perceives this situation as well as the stakeholders involved in the public care process: managers of services and nominated adults by young people. We present results from a total of 96 interviews conducted in Catalonia. The young people interviewed (N = 35) were between 19 and 22 years old and were selected among those who at the age of 16 were still in care and had good academic results and the capacity andmotivation to continue studying. These young people were interviewed twice, the second a year after to follow the achievement of their training plans. The resultsshow their perception concerning the circumstances that make it easier or difficult to continue studying. Moreover, the results show the matches, mismatches anddiversity among their answers and those of other stakeholders interviewed about what factors facilitate and difficult the education. These results suggest the need for an in-depth review on the representations about the formal education of children in care from professionals and care policies, and how they address the support they need to participate in education

L’altre Segon Quintet : anàlisi formal i rítmic de l’evolució de la interpretació del repertori en els concerts en directe del Segon Quintet de Miles Davis

“L’altre Segon Quintet. Anàlisi formal i rítmic de l’evolució de la interpretació del repertori en els concerts en directe del Segon Quintet de Miles Davis” és un estudi històric i analític de la música de Miles Davis i el seu famós “Segon Quintet”. A diferència de la majoria de publicacions sobre aquesta banda, es centra únicament en els concerts en directe i el repertori que hi tocaven. Per treure a la llum la “màgia” que hi havia, he fet unes transcripcions amb un mètode propi de diverses versions de les mateixes peces al llarg dels anys i he anotat tots els fets rellevants en aspectes d’arranjaments, plantejaments estètics i interacció entre solistes i secció rítmica. Finalment he comprovat que aquesta “màgia” és fruit d’unes fórmules pautades i no és tan espontània com sembla en una primera escolta. Per altra banda, tots els músics de la banda contribueixen al so del grup, demostrant així la seva condició d’indispensables per la banda.

THE FORMAL AND THE FORMALIZED: THE CASES OF SYLLOGISTIC AND SUPPOSITION THEORY

As a discipline, logic is arguably constituted of two main sub-projects: formal theories of argument validity on the basis of a small number of patterns, and theories of how to reduce the multiplicity of arguments in non-logical, informal contexts to the small number of patterns whose validity is systematically studied (i.e. theories of formalization). Regrettably, we now tend to view logic 'proper' exclusively as what falls under the first sub-project, to the neglect of the second, equally important sub-project. In this paper, I discuss two historical theories of argument formalization: Aristotle's syllogistic theory as presented in the "Prior Analytics", and medieval theories of supposition. They both illustrate this two-fold nature of logic, containing in particular illuminating reflections on how to formalize arguments (i.e. the second sub-project). In both cases, the formal methods employed differ from the usual modern technique of translating an argument in ordinary language into a specially designed symbolism, a formal language. The upshot is thus a plea for a broader conceptualization of what it means to formalize.

Formal semantics for propositional attitudes

Contemporary logic is confined to a few paradigmatic attitudes such as belief, knowledge, desire and intention. My purpose is to present a general model-theoretical semantics of propositional attitudes of any cognitive or volitive mode. In my view, one can recursively define the set of all psychological modes of attitudes. As Descartes anticipated, the two primitive modes are those of belief and desire. Complex modes are obtained by adding to primitive modes special cognitive and volitive ways or special propositional content or preparatory conditions. According to standard logic of attitudes (Hintikka), human agents are either perfectly rational or totally irrational. I will proceed to a finer analysis of propositional attitudes that accounts for our imperfect but minimal rationality. For that purpose I will use a non standard predicative logic according to which propositions with the same truth conditions can have different cognitive values and I will explicate subjective in addition to objective possibilities. Next I will enumerate valid laws of my general logic of propositional attitudes. At the end I will state principles according to which minimally rational agents dynamically revise attitudes of any mode.

Uma nota sobre a lógica formal de Kant

O artigo apresenta um problema que surge da combinação da teoria kantiana dos juízos analíticos com a sua adesão oficial à silogística. Argumenta-se em seguida que o problema só pode ser inteiramente solucionado pelo reconhecimento de que a lógica com a qual Kant de fato operava não é consistente nem com a silogística, nem com a lógica clássica, consistindo, de fato, em uma espécie de lógica inclusiva.

HILBERT BETWEEN THE FORMAL AND THE INFORMAL SIDE OF MATHEMATICS

Abstract: In this article we analyze the key concept of Hilbert's axiomatic method, namely that of axiom. We will find two different concepts: the first one from the period of Hilbert's foundation of geometry and the second one at the time of the development of his proof theory. Both conceptions are linked to two different notions of intuition and show how Hilbert's ideas are far from a purely formalist conception of mathematics. The principal thesis of this article is that one of the main problems that Hilbert encountered in his foundational studies consisted in securing a link between formalization and intuition. We will also analyze a related problem, that we will call "Frege's Problem", form the time of the foundation of geometry and investigate the role of the Axiom of Completeness in its solution.

PROLEGÓMENOS PARA UNA TEORÍA FORMAL DE ESTRUCTURAS (DESPUÉS DE N.DA COSTA)

Resumen El articulo tiene por objetivo la reconstrucción alternativa del concepto de estructura, motivado por los articulos (1) y (3), como una generalización abstracta de lo que es un objeto matemático. Primero, mostramos su construcción, que tiene que ver con la teoría de tipos y orden en lógica, dando a lugar a propiedades y varios ejemplos interesantes. Luego avanzamos hacia una semántica concreta, para su análisis, y para permitirnos operar sobre ellas, sabiendo de este modo, lo que es "lo verdadero en ella". Obtenido ello, mostraremos los resultados de reducción de orden y de individuos, pero vistos en este contexto, así formalizando completamente en nuestra teoría de tipos la discusión de (1) (Ver también (2) y (3)) sobre estos temas.
