Concept definition in knowledge management : the development of an organizational memory scale

Theorists and researchers in the field of Knowledge Management are frequently frustrated by issues with concept definition, as illustrated by the following comment "there remains disagreement on methodologies, definitions and processes" from the summary article "Issues Raised at ECKM, 2008". How can we clearly define constructs of interest? How can we further research and understanding in the field if we are speaking with different vocabularies? This paper illustrates some of these issues by describing the concept definition process involved in the development of an organizational memory scale. The example being used to illustrate these issues was a self-report scale of organizational memory developed to survey experienced workers' attitudes to mentoring others to pass on their knowledge. The current research sought to differentiate between the types of organizational knowledge that experienced workers have and the possible relationships these have with attitudes pertaining to knowledge transfer via mentoring. Defining the construct to be measured is the vital first ingredient in scale development. Many researchers lament that the concept of organizational memory is a "rather loosely defined and under-developed concept" (e.g. Johnson & Paper, 1998, p.504), and this hints at the challenges that concept definition can entail. Furthermore, in the early stages of this particular project it became clear that the organizational memory scale had similar aims, and was able to borrow from, an existing sale of organizational socialization (Chao, O'Leary-Kelly, Woolf, Klein & Gardner, 1994). This paper describes the concept definition process involved in the development of the scale along with results from the exploratory factor analysis. There is a discussion of the relative contribution that the organizational memory scale makes alongside the existing measure of socialization (Chao et al., 1994), along with goals for further development.

Processing of wh-questions in a case of posterior cortical atrophy

Posterior cortical atrophy (PCA) is a type of dementia that is characterized by visuo-spatial and memory deficits, dyslexia and dysgraphia, relatively early onset and preserved insight. Language deficits have been reported in some cases of PCA. Using an off-line grammaticality judgement task, processing of wh-questions is investigated in a case of PCA. Other aspects of auditory language are also reported. It is shown that processing of wh-questions is influenced by syntactic structure, a novel finding in this condition. The results are discussed with reference to accounts of wh-questions in aphasia. An uneven profile of other language abilities is reported with deficits in digit span (forward, backward), story retelling ability, comparative questions but intact abilities in following commands, repetition, concept definition, generative naming and discourse comprehension.

Revising the critical care family needs inventory for the emergency department

Background: The Critical Care Family Needs Inventory (CCFNI) has been used widely over the last two decades for analysing the needs of family members in the intensive care unit. However, it has significant limitations as a needs assessment tool for use with families in the Emergency Department (ED). This paper discusses the methodological challenges encountered during the process of reviewing and adapting this tool for use in the ED. Aims: The purpose of this study was to revise and adapt the CCFNI for use with a population of family members of critically ill patients in an Australian Emergency Department. Instrument: The process of tool revision, adaptation and reconstruction included: critique of the CCFNI; concept definition; item review; content and structure revision; scale revision; and testing with a sample of the target population. Methods: Data collection methods were aimed at accessing a vulnerable population, while enhancing response rate and data quality. A sample of 84 relatives of critically ill patients from one Melbourne Metropolitan Emergency Department was used, 73% of whom returned questionnaires. Results: Pilot data were examined with the specific purpose of identifying elements of the tool that required refinement or modification. Methods used for establishing reliability and validity of the revised tool provided satisfactory results. Limitations: Limitations of this study include inadequate sample size for exploratory factor analysis, and an incomplete response set for some items, which influenced item analysis. Conclusion: The process used for addressing the identified methodological issues in reviewing and adapting the CCFNI for use in the ED provides a framework for adapting an established tool for a specific purpose.

Um estudo exploratório sobre a imagem conceitual de estudantes universitários acerca do conceito de limite de função

Esta é uma pesquisa de caráter exploratório, cujo objetivo foi investigar os elementos que compõem a imagem conceitual de estudantes universitários sobre o conceito de limite de uma função de uma variável real. O estudo envolveu 25 estudantes do curso de licenciatura em matemática de duas universidades públicas no estado do Pará (Brasil) e constituiu-se de duas etapas. Primeiramente, aplicamos um questionário que continha tarefas relacionadas aos aspectos conceituais de limite de uma função de uma variável. A segunda etapa consistiu na realização de entrevistas com seis sujeitos que foram selecionados devido às imagens conceituais evocadas por eles na etapa anterior, e que por sua vez, encontravam-se em conformidade com os quatro Temas de Discussão (TD) que nortearam essas entrevistas. A análise dos resultados baseou-se, sobretudo, na teoria de Tall e Vinner (1981) e Vinner (1991), bem como nos estudos realizados por Cottril et al (1996), Jordaan (2005), Juter (2006), Nair (2009), dentre outros, que compuseram a fundamentação teórica do presente estudo. Dentre os resultados obtidos, ressaltamos que os estudantes relacionam o conceito de limite de uma função de uma variável real com interpretações estáticas e/ou dinâmicas que, em alguns momentos, constituíram-se como fatores de conflito potencial, conforme destacado por Vinner (1991). Além disso, evidenciamos que algumas das imagens conceituais evocadas pelos sujeitos investigados não se fizeram coerentes, fato que os influenciou a construir uma definição conceitual pessoal diferente da definição conceitual formal de limite de uma função de uma variável real.

Petrofac International Limited: el mercadeo interno, una estrategia efectiva en el manejo de personal

Como futuros administrados es importante recordar que nuestra función no será únicamente crear una empresa y generar constantemente ingresos. Esto es una de tantas tareas que tiene una persona que se encamina por crear o ser parte de una empresa, sea grande o pequeña siempre existirán variables que con los años se han convertido más y más indispensables en los procesos de este recorrido. El tema principal de nuestro estudio de caso es entender el concepto del endomarketing o como muchos lo conocen marketing interno; en pocas palabras es algo que por años se ha visto su efectividad en la productividad y satisfacción de los empleados. Google es una de las multinacionales más grandes del mundo, que el ultimo reconocimiento fue por parte de uno de los ranking más influyentes “The World’s Billionaries” ocupando como el CEO de la compañía Larry Page el puesto #12 , que por años ha sabido invertir en su recurso más importante que son sus empleados. En una entrevista con la revista Fortune, Larry exclama que “es importante que la empresa sea una familia, que las personas sientan que son parte de la empresa, y que la empresa es como una familia para ellos. Cuando se trata a las personas de esa manera, se obtiene una mejor productividad”. Con este pequeño ejemplo e idea de cómo una de las marcas más influyentes en el mundo ha fortalecido su mejor recurso por años el cual le ha remunerado con el éxito que tiene hoy en día. Entonces es como el mercadeo interno o endomarketing siendo uno de los conceptos tratados en el mercadeo en general hoy en día, logrando meterse como un modelo de negocio en la mayoría de empresas que existen hoy. Este es uno de los motivos que nos motivó para desarrollar este estudio de caso que verán a continuación, el cual se basa en la investigación y análisis de variables que comprenden a la empresa Petrofac, y si bien ha sabido implementar el concepto en sus procesos diarios. El estudio de caso describe como a través de los años ha sabido implementar con éxito la herramienta de evaluación y análisis del mercado interno a los empleados que constituyen hoy en día Petrofac International Limited. Abarcaremos primero con los objetivos del estudio, seguido del inicio y crecimiento de la empresa en los últimos años, en que países tiene presencia y cuáles son sus proyectos más importantes hoy en día. El estudio de caso será implementado por un tipo de investigación descriptiva, que con la recopilación de suficiente información tanto cuantitativa como cualitativa nos ira fortaleciendo la hipótesis principal, usaremos datos estadísticos que serán recopilados de encuestas, entrevistas y focus group. Al final con el análisis y a las conclusiones que lleguemos se busca demostrar el impacto positivo que ha tenido los empleados de diferentes países y de diferentes culturas que poco a poco han influenciado a la empresa para alcanzar el éxito que ha logrado hasta ahora, y de la misma forma como la empresa ha influenciado en cada una de las vidas de estas personas sin importar el lugar en el que estén laborando, siempre la empresa busca que se sientan parte de ella. Como resultados generales, se obtienen argumentos que sustentan que la implementación del mercadeo interno le permite a la empresa generar ventajas competitivas y dinámicas, que son desarrolladas internamente para un futuro reflejarlas ante los clientes externos. El estudio permitió concluir que el mercadeo interno debe ser una estrategia de comunicación dentro de una empresa convirtiéndose de primera necesidad para la compañía, pues los beneficios que genera son cada vez más necesarios para cada área que abarca el negocio.

Concept of "Crossover Point" and its Application on Threshold Voltage Definition for Undoped-Body Transistors

As the conventional MOSFET's scaling is approaching the limit imposed by short channel effects, Double Gate (DG) MOS transistors are appearing as the most feasible candidate in terms of technology in sub-45nm technology nodes. As the short channel effect in DG transistor is controlled by the device geometry, undoped or lightly doped body is used to sustain the channel. There exits a disparity in threshold voltage calculation criteria of undoped-body symmetric double gate transistors which uses two definitions, one is potential based and the another is charge based definition. In this paper, a novel concept of "crossover point'' is introduced, which proves that the charge-based definition is more accurate than the potential based definition.The change in threshold voltage with body thickness variation for a fixed channel length is anomalous as predicted by potential based definition while it is monotonous for charge based definition.The threshold voltage is then extracted from drain currant versus gate voltage characteristics using linear extrapolation and "Third Derivative of Drain-Source Current'' method or simply "TD'' method. The trend of threshold voltage variation is found same in both the cases which support charge-based definition.

Justifying threshold voltage definition for undoped body transistors through ``crossover point'' concept

Two different definitions, one is potential based and the other is charge based, are used in the literatures to define the threshold voltage of undoped body symmetric double gate transistors. This paper, by introducing a novel concept of crossover point, proves that the charge based definition is more accurate than the potential based definition. It is shown that for a given channel length the potential based definition predicts anomalous change in threshold voltage with body thickness variation while the charge based definition results in monotonous change. The threshold voltage is then extracted from drain current versus gate voltage characteristics using linear extrapolation, transconductance and match-point methods. In all the three cases it is found that trend of threshold voltage variation support the charge based definition.

Interlink decision making index (IDMI) -- a simple tool/concept to assist decision making for sustainability Part 1: definition of IDMI

There is an apparent gap between the LCA or other assessment's outcomes and its effective application in the decision making process. It is needed to provide to the decision makers a simple, less human interfered mechanism that integrates all the key criteria (environmental, economic, technical and safety etc.). The proposed index: Interlink Decision Making Index (IDMI) has all these features: simple, interlink (all criteria) and automatically and quantified influence of critical criteria (ie. no human weighting needed) and is able to assist the multi-criteria decision making for sustainability based on the outcomes of specific assessments (eg. LCA, ElA etc.). The index represents a pure numerical value and does not necessarily have any physical meanings, but it reflects the total merits of a particular option once the normal decision making criteria and (up to two) critical criteria (CC) have been chosen. Then, without arbitrarily weighting process, the comparison and selection of the best possible option, ie. decision can be made based on the derived IDMI results. Two hypothetical examples are presented in part 2 of the paper to demonstrate the application of the IDMI concept and it's differences with the traditional "tabular method" in the decision making process.
