THE PURPOSE OF THIS CHAPTER IS TO PRESENT A THEORETICAL PROPOSAL FOR THE ADOPTION OF A PROFESSIONAL ROLE CHARACTERIZED BY THINKING AND ACTING CRITICALLY, IN ORDER TO GENERATE EDUCATIONAL CHANGES. EDUCATIONAL PSYCHOLOGY HAS BEEN SHAPED BY THEORETICAL AND EPISTEMOLOGICAL PERSPECTIVES THAT HAVE NOT PLACED EMPHASIS ON THE REFLECTION OR DISCUSSION OF ISSUES RELEVANT TO DISCIPLINE, WHICH HAS LED TO ESTABLISHMENT OF AREAS, FUNCTIONS AND ROLES THAT ARE UNCLEAR AND LACKING CONSENSUS, FROM A PARADIGMATIC LOGIC OF SIMPLICITY. IT IS PROPOSED, THROUGH THE BIBLIOGRAPHIC REVIEW OF ARTICLES AND BOOK CHAPTERS, A POSITION OF EDUCATIONAL PSYCHOLOGY THAT PROMOTES CRITICAL THINKING AS AN ESSENTIAL PART OF THE PROFESSIONAL ROLE, WHICH ALLOWS, ON THE ONE HAND, TO DISCUSS THE FOUNDATIONAL BASIS OF THIS DISCIPLINE, ALLOWING GREATER CLARITY ON THE SCOPE OF THE SCIENTIFIC AND THE PROFESSIONAL FIELD. ON THE OTHER HAND, IT ALLOWS THE DEVELOPMENT OF A FACET OF PROMOTION OF CHANGES IN THE EDUCATIONAL COMMUNITY, FROM THIS SAME CRITICAL ROLE, BRINGING IT CLOSER TO A PARADIGM OF COMPLEXITY. FINALLY, THE ADVANTAGES AND DISADVANTAGES OF THIS POSITION ARE DISCUSSED, AND IT IS CONCLUDED THAT THIS VIEW WOULD ESTABLISH A NEW PERSPECTIVE OF EDUCATIONAL PSYCHOLOGY, WHICH CAN BE COMPLEMENTED BY THE TRADITIONAL VIEW.

IN THIS PAPER WE STUDY THE INVERSE PROBLEM ARISING IN THE MODEL DESCRIBING THE TRANSPORT OF TWO-PHASE FLOW IN POROUS MEDIA. WE CONSIDER SOME PHYSICAL ASSUMPTIONS SO THAT THE MATHEMATICAL MODEL (DIRECT PROBLEM) IS AN INITIAL BOUNDARY VALUE PROBLEM FOR A PARABOLIC DEGENERATE EQUATION. IN THE INVERSE PROBLEM WE WANT TO DETERMINE THE COEFFICIENTS (FLUX AND DIFFUSION FUNCTIONS) OF THE EQUATION FROM A SET OF EXPERIMENTAL DATA FOR THE RECOVERY RESPONSE. WE FORMULATE THE INVERSE PROBLEM AS A MINIMIZATION OF A SUITABLE COST FUNCTION AND WE DERIVE ITS NUMERICAL GRADIENT BY MEANS OF THE SENSITIVITY EQUATION METHOD. WE START WITH THE DISCRETE FORMULATION AND, ASSUMING THAT THE DIRECT PROBLEM IS DISCRETIZED BY A FINITE VOLUME SCHEME, WE OBTAIN THE DISCRETE SENSITIVITY EQUATION. THEN, WITH THE NUMERICAL SOLUTIONS OF THE DIRECT PROBLEM AND THE DISCRETE SENSITIVITY EQUATION WE CALCULATE THE NUMERICAL GRADIENT. THE CONJUGATE GRADIENT METHOD ALLOWS US TO FIND NUMERICAL VALUES OF THE FLUX AND DIFFUSION PARAMETERS. ADDITIONALLY, IN ORDER TO DEMONSTRATE THE EFFECTIVENESS OF OUR METHOD, WE PRESENT A NUMERICAL EXAMPLE FOR THE PARAMETER IDENTIFICATION PROBLEM.

HIERARCHICAL PRODUCTION PLANNING IS A WIDELY UTILIZED METHODOLOGY FOR REAL WORLD PRODUCTION PLANNING SYSTEMS, WITH THE AIM TO ESTABLISH ALTERNATIVE DECISION-MAKING LEVELS OF THESE PLANNING ISSUES. FOR TACTICAL PURPOSES, THE METHODOLOGY CONSIDERING ONE OR TWO DISAGGREGATION LEVELS, IN ORDER TO MEET THE FINAL DEMAND. FREQUENTLY, THE HIERARCHICAL APPROACH UTILIZES DIFFERENT DETERMINISTIC OPTIMIZATION MODELS THAT IMPOSE APPROPRIATE CONSTRAINTS TO KEEP COHERENCE OF THE PLAN ON THE PRODUCTION SYSTEM. HOWEVER, IN MANY SITUATIONS, A DETERMINISTIC MODEL ISN?T APPROPRIATE FOR CAPTURING UNCERTAIN DEMAND BEHAVIOR THAT IS PRESENT IN SOME REAL-WORLD APPLICATIONS. ONE UNCERTAINTY TO BE CONSIDERED IS THE INVOLVEMENT OF OPTIMIZATION MODELS IN WHICH THIS PARAMETER IS REPRESENTED BY A RANDOM VARIABLE OR A SET OF SCENARIOS. FOR THAT PURPOSE, IN THE PROPOSED CHAPTER, WE INTRODUCE A HIERARCHICAL APPROACH USING DIFFERENT STOCHASTIC OPTIMIZATION MODELS, IN ORDER TO DETERMINE OPTIMAL ALLOCATION OF RESOURCES AT THE TACTICAL LEVEL, AS WELL AS IN REFERENCE TO THE MOST IMMEDIATE PLANNING HORIZON, IN ORDER TO MEET UNCERTAIN DEMANDS. WE ALSO PRESENT A CASE STUDY APPLYING THE PROPOSED METHODOLOGY TO AN INDUSTRIAL COMPANY THAT PRODUCES DIFFERENT HOUSE HOLD ELECTRICAL APPLIANCES, ELUCIDATING THE RELEVANCY OF THE ADOPTED METHODOLOGY.

ALGINATE DISPLAYS EXCELLENT BIOCOMPATIBILITY AND BIODEGRADABILITY AND HAS MANY DIFFERENT APPLICATIONS IN BIOMEDICINE AND THE FOOD INDUSTRY. ALGINATE-BASED BIOMATERIALS CAN BE USED IN REGENERATIVE MEDICINE AS A DRUG DELIVERY SYSTEM AND CELL CARRIER. IN FOOD APPLICATIONS, IT IS A POPULAR INGREDIENT, FOOD ADDITIVE, AND CARRIER OF ESSENTIAL COMPONENTS IN ALGINATE GEL ENCAPSULATION. THE ANIONIC POLYSACCHARIDE CAN BE EASILY MODIFIED VIA CHEMICAL AND PHYSICAL REACTIONS TO OBTAIN THREE-DIMENSIONAL (3D) SCAFFOLDING DERIVATIVES SUCH AS HYDROGELS, MICROSPHERES, MICROCAPSULES, SPONGES, FOAMS, AND FIBERS. ALGINATE-DERIVED SUPPORTED MATRICES? BIODEGRADABILITY, BIOCOMPATIBILITY, MECHANICAL STRENGTH, AND EXCEPTIONAL CHELATING PROPERTIES MAKE THEM USEFUL FOR A BROAD RANGE OF APPLICATIONS. THIS CHAPTER FOCUSES ON RECENT ADVANCES IN THE USE OF ALGINATE AND ITS DERIVATIVES IN THE BIOMEDICAL AND FOOD INDUSTRIES, INCLUDING USES SUCH AS WOUND HEALING, CARTILAGE AND BONE REGENERATION, DRUG DELIVERY, FOOD ADDITIVES, AND, IN ENCAPSULATED FORM, CARRIERS OF MICRONUTRIENTS AND BIOACTIVE COMPONENTS.

ESTE LIBRO EXPONE ASPECTOS METODOLÓGICOS CLAVES PARA LA ADECUADA APLICACIÓN DE LOS ENFOQUES DE CICLO DE VIDA A LA GESTIÓN DE LOS RECURSOS HÍDRICOS, HACIENDO REFERENCIA AL ESTADO DEL ARTE Y A LOS DEBATES QUE APUNTAN LOS RETOS METODOLÓGICOS MÁS RELEVANTES, EN UNA ESTRUCTURA DE 5 CAPÍTULOS.

THIS BOOK SHOWED US THAT TODAY, PUBLIC AND PRIVATE ORGANIZATIONS ARE INTERESTED IN KNOWING THE VIEWS OF USERS ON THE QUALITY OF THE SERVICE. THEREFORE, THE AIM OF THE RESEARCH IS TO DETERMINE THE RELATIONSHIP BETWEEN THE FACTORS OF QUALITY MANAGEMENT AND METABOLIC CONTROL OF TYPE 2 DIABETES USERS A RURAL AREA OF CHILE.MANAGEMENT FACTORS TO ASSESS INCLUDE: USER SUPPORT, THE SPEED OF ATTENTION AND PROFESSIONALISM OF THE STAFF.

ISMAEL ES UN HOMBRE DE FAMILIA Y UN EXITOSO EMPRESARIO QUE TUVO QUE LIDIAR CON DUROS EVENTOS DESDE LA NIÑEZ. NO OBSTANTE, LOGRA CON ESFUERZO Y PERSEVERANCIA LO QUE MUCHOS DESEAN, PERO POCOS ALCANZAN. UNA MAÑANA AL DESPERTAR SE ENCUENTRA EN UN LUGAR DESCONOCIDO, PERO EXTRAÑAMENTE FAMILIAR, EN COMPAÑÍA DE UNA PEQUEÑA NIÑA A LA QUE LE RELATA PARTES DE SU VIDA. ASÍ COMIENZA UN RECORRIDO POR SU HISTORIA, ENTRE LAS DÉCADAS DE 1970 Y 1980, MARCADA POR EVENTOS QUE DEMUESTRAN QUE UNA PERSONA PUEDE ROMPER LOS DOGMAS ESTABLECIDOS POR UNA SOCIEDAD Y LOGRAR VIVIR Y SER FELIZ. ESCRITO DESDE LOS FUNDAMENTOS DE LA PSICOLOGÍA POSITIVA Y DEL COACHING, ANTES DE VIVIR, BASADA EN VARIAS HISTORIAS REALES, INTEGRADAS EN LA VIDA DE ISMAEL, ES UNA NOVELA QUE INSPIRARÁ A SUS LECTORES A NO RENDIRSE Y A SEGUIR ADELANTE, AUNQUE TODO PAREZCA EN SU CONTRA.

THIS OVERVIEW BRINGS TOGETHER WIDELY SCATTERED AND DISPARATE LITERATURE CONCERNING NATURAL PRODUCTS FROM LATIN-AMERICAN PLANTS; IN PARTICULAR, STUDIES BASED ON SCREENING OF SECONDARY METABOLITES ARE REVIEWED IN THE CONTEXT OF THE DEVELOPMENT OF NEW ANTIOXIDANTS AND BIOCIDES.
