Texture, composition and provinance of innershelf sediments between Narakkal and Purakkad, Kerala with special reference to the formation of Mud Banks

The continental shelf of southwest coast of India (Kerala) is broader and . flatter compared to that of the east coast. The unique characteristic feature of the study area (innershelf between Narakkal and Purakkad) is the intermittent appearance of 'mud banks' at certain locations during southwest monsoon. The strong seasonality manifests significant changes in the wind, waves, currents, rainfall, drainage etc., along this area. Peculiar geomorphological variation with high, mid and lowlands in the narrow strip of the hinterland, the geological formations mainly consisting of rocks of metamorphic origin and the humid tropical weathering conditions play significant role in regulating the shelf sedimentation. A complementary pattern of distri bution is observed for clay that shows an abundance in the nearshore. Silt, to a major extent, depicts semblance with clay distribution . Summation of the total asymmetry of grain size distribution are inferred from the variation of skewness and kurtosis.Factor I implies a low energy regime where the transportation and deposition phases are controlled mostly by pelagic suspension process as the factor loadings are dominant on finer phi sizes. The second Factor is inferred to be the result of a high energy regime which gives higher loadings on coarser size fractions. The third Factor which might be a transition phase (medium energy regime) representing the resultant flux of coastal circulation of the re-suspension/deposition and an onshoreoffshore advection by reworking and co-deposition of relict and modern sediments. The spatial variations of the energy regime based on the three end-member factor model exhibits high energy zone in the seaward portion transcending to a low energy one towards the coast.From the combined analysis of granulometry and SEM studies, it is concluded that the sandy patches beyond 20 m depth are of relict nature. They are the resultant responses of beach activity during the lower stand of sea level in the Holocene. Re-crystallisation features on the quartz grains indicate that they were exposed to subaerial weathering process subsequent to thei r deposition

Efficacy of Cluster- Based Approach for the revival of Handloom Co-operative Societies in Kerala- with special reference to Thiruvananthapuram and Kannur Districts

one of the key sectors, identified by the Department of Industries Government of Kerala, for the cluster development initiative is Handloom, which gives employment to over over 50,000 people directly. Despite its age old tradition and fame, the performance of the sector vis-à-vis power looms is not very rosy owing to (i) competition from cheap power loom cloth from other states (ii) scarcity of quality yarn (iii) price escalation of yarn, dyes, chemicals and other raw materials (iv) the shrinking market for handlooms in Kerala (v) non-demand based production and inadequacy of new designs and (vi) inefficiencies in the system, particularly in the co-operative sector. Cluster based approach is adopted in the handloom sector with the objective of providing necessary support mechanism to come out of the crisis that the sector faces now. While four cluster schemes are being implemented in Kerala, it is under IHDS-CDP that the State got a sizeable number of clusters benefiting a large number of societies and weavers- 24 handloom clusters, bringing 152 handloom co-operative societies and over 19,800 handloom workers under the Programme. This research attempts to revisit the underlying rationale and context of the new direction and would attempt to broadly analyze the growth trends under the influence of cluster model adopted by the State IHDS-CDP for the revival of handloom sector through a detailed study of the handloom co-operative societies in Kerala. If handloom sector in Kerala can be revived using cluster based approach, it can be easily concluded that cluster is capable of taking the MSME in Kerala to a ‘high growth path.’ The study is aimed at understanding how best clusters emerge as appropriate industrial organization suitable for the current global structure of manufacture

Operational Flexibility: A Model for Effective Project Management

The aim of this study is to investigate the role of operational flexibility for effective project management in the construction industry. The specific objectives are to: a) Identify the determinants of operational flexibility potential in construction project management b) Investigate the contribution of each of the determinants to operational flexibility potential in the construction industry c) Investigate on the moderating factors of operational flexibility potential in a construction project environment d) Investigate whether moderated operational flexibility potential mediates the path between predictors and effective construction project management e) Develop and test a conceptual model of achieving operational flexibility for effective project management The purpose of this study is to findout ways to utilize flexibility inorder to manage uncertain project environment and ultimately achieve effective project management. In what configuration these operational flexibility determinants are demanded by construction project environment in order to achieve project success. This research was conducted in three phases, namely: (i) exploratory phase (ii) questionnaire development phase; and (iii) data collection and analysis phase. The study needs firm level analysis and therefore real estate developers who are members of CREDAI, Kerala Chapter were considered. This study provides a framework on the functioning of operational flexibility, offering guidance to researchers and practitioners for discovering means to gain operational flexibility in construction firms. The findings provide an empirical understanding on kinds of resources and capabilities a construction firm must accumulate to respond flexibly to the changing project environment offering practitioners insights into practices that build firms operational flexibility potential. Firms are dealing with complex, continuous changing and uncertain environments due trends of globalization, technical changes and innovations and changes in the customers’ needs and expectations. To cope with the increasingly uncertain and quickly changing environment firms strive for flexibility. To achieve the level of flexibility that adds value to the customers, firms should look to flexibility from a day to day operational perspective. Each dimension of operational flexibility is derived from competences and capabilities. In this thesis only the influence on customer satisfaction and learning exploitation of flexibility dimensions which directly add value in the customers eyes are studied to answer the followingresearch questions: “What is the impact of operational flexibility on customer satisfaction?.” What are the predictors of operational flexibility in construction industry? .These questions can only be answered after answering the questions like “Why do firms need operational flexibility?” and “how can firms achieve operational flexibility?” in the context of the construction industry. The need for construction firms to be flexible, via the effective utilization of organizational resources and capabilities for improved responsiveness, is important because of the increasing rate of changes in the business environment within which they operate. Achieving operational flexibility is also important because it has a significant correlation with a project effectiveness and hence a firm’s turnover. It is essential for academics and practitioners to recognize that the attainment of operational flexibility involves different types namely: (i) Modification (ii) new product development and (iii) demand management requires different configurations of predictors (i.e., resources, capabilities and strategies). Construction firms should consider these relationships and implement appropriate management practices for developing and configuring the right kind of resources, capabilities and strategies towards achieving different operational flexibility types.

Research through DESIGN through research - a problem statement and a conceptual sketch

This paper re-addresses the issue of a lacking genuine design research paradigm. It tries to sketch an operational model of such a paradigm, based upon a generic design process model, which is derived from basic notions of evolution and learning in different domains of knowing (and turns out to be not very different from existing ones). It does not abandon the scientific paradigm but concludes that the latter has to be embedded into / subordinated under a design paradigm.

Mobiles Lernen

In ihrer Arbeit "Mobiles Lernen. Analyse des Wissenschaftsprozesses der britischen und deutschsprachigen medienpädagogischen und erziehungswissenschaftlichen Mobile-Learning-Diskussion." zeichnet Judith Seipold die Phasen und Entwicklungslinien der bisherigen und naturwüchsigen Diskussion um das Mobile Lernen nach. Dabei eröffnet sie mit ihrer Analyse des vornehmlich britischen Wissenschaftsprozesses des Mobilen Lernens ab Beginn des 21. Jahrhunderts den Blick auf die Struktur der medienpädagogischen und erziehungswissenschaftlichen Mobile-Learning-Diskussion, auf deren Kontexte, Bezugspunkte, Perspektiven und theoretische Schwerpunkte, aber auch Erfolge und Problembereiche in der praktischen Umsetzung des Lernens mit Mobiltechnologien in formalisierten Lernkontexten wie dem des Schulunterrichts. Auf diese Weise liefert die Autorin eine Systematik, die nicht nur die britische Diskussion für die deutschsprachige Medienpädagogik verfügbar macht, sondern auch eine neue und systematisch begründete Reflexionsebene für eine aktuelle medienpädagogische Entwicklung – das Mobile Lernen – bildet. Zunächst widmet sich die Autorin der Analyse des Wissenschaftsprozesses der bisherigen britischen und teils auch der deutschsprachigen Mobile-Learning-Diskussion. Um diesen Prozess in seiner Struktur greifbar zu machen, skizziert sie die Bezugsdisziplinen, aus denen die medienpädagogische und erziehungswissenschaftliche Mobile-Learning-Forschung schöpft, arbeitet die Legitimationsbasis auf, auf die sich Mobiles Lernen stützt, zeichnet die historische Entwicklung der Diskussion nach, die sowohl Alltagsnutzung von Mobiltechnologien als auch den Fachdiskurs einschließt, und erläutert innerhalb ihres Modells der Phasen und Entwicklungslinien Mobilen Lernens Theorien, Konzepte und Modelle, die in der Mobile-Learning-Community als zentral für Analyse und Planung Mobilen Lernens erachtet werden. Konzepte und Modelle, die in der Mobile-Learning-Diskussion die Rolle der Lernenden in das Zentrum der Betrachtungen rücken und eine explizite Handlungsorientierung unterstützen, sind Kernbereich des theoriebasierten Teils der Arbeit. Überlegungen zu einer „Sozio-kulturellen Ökologie Mobilen Lernens“, zu „user-generated contexts“ und zu einer „kulturökologisch informierten Didaktik des Mobilen Lernens“ sind dabei sowohl reflektierende Einordnung aktueller Konzepte und Modelle als auch theoretische und konzeptionelle Basis für die praktische Umsetzung Mobilen Lernens. Um die Rolle der Handlungskompetenzen, kulturellen Praktiken und Strukturen der Lerner bei der Nutzung von Mobiltechnologien für Lernen analytisch zu fassen, finden im Praxis-Kapitel Planungs- und Analyseschemata unter Rückgriff auf Beispiele aus der Praxisforschung und der Implementierung mobilen Lernens in den Schulunterricht Anwendung. Ihre Erörterungen rahmt die Autorin abschließend kritisch und weist zum einen auf bildungspolitische, strukturelle und handlungspraktische Implikationen hin, die sich aus der Mobile-Learning-Diskussion ergeben; zum anderen lenkt sie das Augenmerk auf Gegensätze und Dialektiken des Mobilen Lernens, die sich im Spannungsfeld zwischen alltäglicher mobiler Mediennutzung und der teils theoretisch informierten schulischen Verwendung von Mobiltechnologien zum Lernen entfalten. Sie gilt es, im weiteren Verlauf der Diskussion zu hinterfragen und aufzulösen.

Model-Based Matching by Linear Combinations of Prototypes

We describe a method for modeling object classes (such as faces) using 2D example images and an algorithm for matching a model to a novel image. The object class models are "learned'' from example images that we call prototypes. In addition to the images, the pixelwise correspondences between a reference prototype and each of the other prototypes must also be provided. Thus a model consists of a linear combination of prototypical shapes and textures. A stochastic gradient descent algorithm is used to match a model to a novel image by minimizing the error between the model and the novel image. Example models are shown as well as example matches to novel images. The robustness of the matching algorithm is also evaluated. The technique can be used for a number of applications including the computation of correspondence between novel images of a certain known class, object recognition, image synthesis and image compression.

The Quadric Reference Surface: Theory and Applications

The conceptual component of this work is about "reference surfaces'' which are the dual of reference frames often used for shape representation purposes. The theoretical component of this work involves the question of whether one can find a unique (and simple) mapping that aligns two arbitrary perspective views of an opaque textured quadric surface in 3D, given (i) few corresponding points in the two views, or (ii) the outline conic of the surface in one view (only) and few corresponding points in the two views. The practical component of this work is concerned with applying the theoretical results as tools for the task of achieving full correspondence between views of arbitrary objects.

Performance-Driven Microfabrication-Oriented Methodology for MEMS Conceptual Design with Application in Microfluidic Device Design

Performance and manufacturability are two important issues that must be taken into account during MEMS design. Existing MEMS design models or systems follow a process-driven design paradigm, that is, design starts from the specification of process sequence or the customization of foundry-ready process template. There has been essentially no methodology or model that supports generic, high-level design synthesis for MEMS conceptual design. As a result, there lacks a basis for specifying the initial process sequences. To address this problem, this paper proposes a performance-driven, microfabrication-oriented methodology for MEMS conceptual design. A unified behaviour representation method is proposed which incorporates information of both physical interactions and chemical/biological/other reactions. Based on this method, a behavioural process based design synthesis model is proposed, which exploits multidisciplinary phenomena for design solutions, including both the structural components and their configuration for the MEMS device, as well as the necessary substances for the chemical/biological/other reactions. The model supports both forward and backward synthetic search for suitable phenomena. To ensure manufacturability, a strategy of using microfabrication-oriented phenomena as design knowledge is proposed, where the phenomena are developed from existing MEMS devices that have associated MEMS-specific microfabrication processes or foundry-ready process templates. To test the applicability of the proposed methodology, the paper also studies microfluidic device design and uses a micro-pump design for the case study.

An alternative method for dating unknown tephras based on a segmented regression model

In CoDaWork’05, we presented an application of discriminant function analysis (DFA) to 4 different compositional datasets and modelled the first canonical variable using a segmented regression model solely based on an observation about the scatter plots. In this paper, multiple linear regressions are applied to different datasets to confirm the validity of our proposed model. In addition to dating the unknown tephras by calibration as discussed previously, another method of mapping the unknown tephras into samples of the reference set or missing samples in between consecutive reference samples is proposed. The application of these methodologies is demonstrated with both simulated and real datasets. This new proposed methodology provides an alternative, more acceptable approach for geologists as their focus is on mapping the unknown tephra with relevant eruptive events rather than estimating the age of unknown tephra.

Resumen tomado de la publicación

Globalización, capitalismo financiero y responsabilidad social empresarial: tensiones estructurales

Los efectos nocivos que el capitalismo financiero y la globalización han tenido sobre los equilibrios sociales y económicos están estrechamente relacionados con los argumentos conceptuales que, como una llamada de atención, han llegado a las corporaciones y las empresas por la responsabilidad social corporativa. Sin embargo, el modelo construido en torno a la acumulación de capital y beneficios han planteado una relación simbiótica en la que ellos mismos son el recurso y el fin de su propia existencia, dando lugar a tensiones estructurales que anula las alternativas de ser sostenible y socialmente responsable al mismo tiempo. El camino que enfrentamos como sociedad, como empresas y como modelo económico sostenible se basa en el trabajo conjunto y los cambios en la manera de abordar el mercado.

Liderazgo, afrontamiento al estrés y toma de decisiones empresariales. una revisión conceptual

El liderazgo basa sus estudios en el análisis de la razón y la emoción, las cuales son dos factores fundamentales para el desarrollo de las personas y la forma como éstas, a través de tácticas propias del liderazgo, demuestran un factor diferenciador entre un equipo de trabajo, creando así, un grupo con unos seguidores y un líder que maneja y soporta la presión de todo el equipo. El estrés es considerado como una tensión que afecta psicológicamente al individuo y adicionalmente produce cambios fisiológicos, que pueden alterar el día a día de las personas en todos los ámbitos de la vida, y el laboral no es la excepción. El estrés puede ser producido por diferentes circunstancias, las cuales son diferentes para cada persona y éstas se presentan en diferentes aspectos de la vida del individuo, es decir, se puede presentar a nivel familiar, educativo, profesional, entre otros dependiendo el individuo que se desee analizar. “… Recibir una calificación reprobatoria en un examen de física, llegar considerablemente tarde a una junta importante, o jugar tiempos extra a muerte súbita en un partido de hockey”. (Hughes, Ginnett, & Curphy, 2007, p. 456) El presente trabajo se enfoca en el estrés laboral, ya que es fundamental para la toma de decisiones, actividad de alta importancia en la gestión directiva, por lo cual se estudiará el efecto que tiene el estrés en la toma de decisiones a niveles empresariales. El estrés laboral ha sido estudiado desde hace más de tres décadas por lo que es posible encontrar definiciones al respecto; McGrath, en 1970 definió el estrés laboral como “el desequilibrio sustancial (percibido) entre la demanda y la capacidad de respuesta del individuo bajo condiciones en las que el fracaso ante esta demanda posee importantes consecuencias (percibidas)”. (Navarro, 2009, p. 86) A partir de esta definición se podría asumir que el estrés laboral tiene un efecto sobre la toma de decisiones sin importar el cargo que el individuo desempeñe. Con el fin de entender y aportar a la administración como disciplina un recurso más para comprender este concepto de la psicología que tiene implicaciones en las organizaciones y en la forma en que los directivos toman decisiones, y así puedan apropiarlas a su diario vivir dentro de las organizaciones, se realizará una monografía que estará basada principalmente en artículos y libros que han introducido este tema anteriormente, pero que no han dado a conocer estos avances a la línea administrativa. Finalmente, con los resultados esperados en esta investigación, aparte de dar a conocer a los administradores los avances de aquellas ciencias sociales existentes anteriormente a la administración y que permiten que el desarrollo administrativo sea mejor, aportando al desarrollo de las capacidades profesionales de los gerentes y empresarios, se espera describir los factores externos que afectan al estrés e identificar cómo éste afecta la toma de decisiones en la dirección.
