Unraveling a Benchmark for Sulphur Akin in the Cochin Estuarine System

The thesis deals with a benchmark study of dissolved and sedimentary sulphur compounds which play prominent roles in the prevailing redox conditions in the selected sites of Cochin estuarine system. Sulphur and its analogues play prominent roles in estuarine biochemical processes. A complete knowledge on the sulphur involvement in these processes is restricted due to the lacking of data on the organic sulphur compounds. Sulphate and sulphide in surface and bottom water and Sulphate, acid volatile sulphide and total sulphur in sediments were studied and correlated to know their interrelations in determining the redox condition of the environment. It also characterises the sediments of the sites on the basis of total organic carbon: total sulphur ratio. The study had attempted to decrease the concentration levels of sulphur in the sedimentary environment by the application of a remedial measure. Knowledge of sulphur uptake by plants from prior literatures has prompted to use phytoremediation for decreasing the sulphur concentration. Phytoremediation is an emerging technology that uses plants to clean up or remediate contaminated soil, sludges, sediments, and ground water through contaminant removal, degradation or containment. The plant selected was wheat grass since earlier studies have shown that wheat grass is effective in remediating pollutants particularly trace metals. So reduction in the concentration of selected trace metals was also focussed.

Benthic ecology of selected prawn culture fields and ponds near Cochin

The thesis on the"Benthic ecology of selected prawn culture fields and ponds near Cochin” was taken up with a view to provide information on the qualitative and quantitative distribution of benthos and their relationships to prawnproduction of different culture ecosystems and to the physico-chemical parameters influencing their production. A two-year observation was carried out in nine selected prawn culture systems including perennial ponds (stations 1 to 4) seasonal fields (stations 5 to 7) and contiguous canals (stations 8 and 9) during December 1988 to November 1989. All macro- and meiobenthic organisms contributing to the faua were identified and their abundance, distribution, diversity, biomass and trophic relationships between benthos and prawns were studied. The environmental variables studied were temperature pH, salinity, dissolved oxygen, alkalinity, nitrite-nitrogen, nitrate-nitrogen, amonianitrogen, phosphate and silicate of bottom water and organic carbon and texture of the soil The thesis is presented in 4 Chapters. Chapter I presents an’ INTRODUCTION to the topic of study and a review of relevant works to bring an awareness to the present status of research in benthos and benthic ecology. Chapter 11, MATERIALS AND MTHODS, includes the techniques of sampling, preservation of samples and methods of analyses of various physico-chemical factors and area covered under the study is also given in this chapter. Chapter III, HYDROGRAPHY deals with the results of investigation and discussion onthe physico-chemical parameters of water and Chapter IV, SEDIMENT covers the sedimentoloical characteristics of the different culture systems followed by a detailed discussion. Chapter V, BOTTOM FAUNA presents an account on the various aspects of benthos and benthic ecology and the details of prawn production. A discussion on the overall assessment of interrelations between abiotic and biotic factors is given in Chapter VI, DISCUSSION. A critical evaluation of the implication of benthic production on prawn production under culture conditions and trophic relationships are also included in this chapter. An executive SUMMARY of the observations made during this study is presented in the final section of the thesis .

El ideal administrativo, nueva visión de la gestión directiva

Las recientes crisis económicas que ha vivido el mundo nos llevan a hacer una reflexión en torno a las responsabilidades que tienen los dirigentes empresariales en los cambios económicos e incluso sociales que se están viviendo. Es por tanto el momento para hacer un análisis más profundo del aporte que la administración, como ciencia, ha hecho a la sociedad. Se ha identificado que la administración permite el desarrollo y crecimiento de un individuo, al tiempo que es un medio de crecimiento y desarrollo para una comunidad, una región y una cultura, lo que se convierte en una realidad indiscutible que nos lleva a reflexionar acerca del porqué, ocurren problemas como las quiebras, ausencia de recursos, y conflictos internos en las organizaciones. En esa medida, una reflexión puede ser que los ideales que ha venido liderando la administración han sido desvirtuados y apartados de una moral y ética empresarial que permita al directivo pensar en algo más que utilidades. Podría parecer extraño decir que la empresa y la acción gerencial deben ir más allá. Podríamos iniciar con el análisis de la obsolescencia de los ideales administrativos o incluso en la ausencia de ideales en la administración. Sobre si se está teniendo en cuenta que la administración que conocemos y aprendemos sigue vigente en un mundo que ha evolucionado y cambiado, el mundo de hoy es distinto al que conocimos incluso en nuestra época de formación profesional, pues se nos enseñó a pensar linealmente, causa y efecto, todo cumple un orden y un plan predeterminado, hoy la visión de certidumbre y control del hombre sobre las decisiones son guiadas por el azar, y por más que el hombre trabaja y diseña estrategias, éstas serán transformadas de acuerdo a las emergencias. Por lo anterior, es importante entender que para avanzar y dejar la obsolescencia en los ideales que ha definido la administración, los directivos deben cambiar su visón y entender la dinámica de interrelación de sus organizaciones en un mundo en permanente caos. Debemos estudiar desde dinámicas diferentes a la de funcionalidad, y saber que es momento para que la administración tenga una nueva visión de la gestión administrativa, por lo que debemos ampliar nuestro horizonte y ver a través de la complejidad. Las decisiones que toman los directivos, las estrategias que definen y la forma de relacionarse con la competencia en mercados altamente competitivos requiere de un cambio en la administración y de un marco ético muy distinto, debe concebirse la gestión directiva y administrativa para mantener y conservar la vida del sector, de la empresa y, por ende, mantener el medio que nos rodea. Por ello se propone ejercer la administración desde la bioética.

Análisis del desarrollo y evolución del objetivo e implementación de las operaciones estrátegicas planteadas en los planes de ordenamiento territorial de Bogotá desde el 2000 al 2013: caso de estudio operación estratégica centro

La planificación urbana en la consolidación de las ciudades ha venido adquiriendo una gran importancia para el desarrollo urbano, a través de instrumentos de gestión urbana. Dentro de esta investigación se analiza las operaciones estratégicas como un instrumento de gestión que ha tenido cambios en su objetivo, alcance e implementación para poder transformar y mejorar a través de intervenciones urbanas los temas físicos, económicos, sociales y culturales dentro de los territorios. A partir de lo anterior, se identificaron cinco elementos que han limitado la implementación de las operaciones estratégicas que son, una visión a largo plazo, la falta de una gerencia especifica, voluntad política, continuidad y la coordinación y comunicación interinstitucional.

A Liderança: uma análise sobre o clima organizacional

No quotidiano de uma organização, facilmente se constatará a influência da liderança sobre o comportamento e o clima organizacional predominantes. Assim, o presente trabalho pretende evidenciar o grau e nível que tais inter-relações poderão assumir no seio das organizações. Neste universo, e tendo sobretudo em conta as exigências da gestão organizacional contemporânea, existem várias questões suscetíveis de ser levantadas. Bastarão as competências técnicas acumuladas e adquiridas para garantir a eficácia de um líder? Por outro lado, poderá este atingir os objetivos a que a organização se propõe se não estiver provido das devidas competências relacionais? Pretende-se igualmente determinar os fatores e condicionalismos que caraterizam o líder carismático, capaz de tornar o clima organizacional favorável ao aumento da produtividade dos trabalhadores, gerir equipas, estimular a motivação, fazer uso efetivo dos recursos e desenvolver a confiança nas pessoas. Além disso, focando a dimensão do comportamento organizacional pretende-se definir o contrato psicológico, a relação líder-membro e como esta influencia os comportamentos, a motivação e o trabalho. O estudo empírico incide sobre uma escola superior: O Instituto Politécnico da Guarda. Os resultados apontam para a existência de uma relação positiva indiciando que o contrato psicológico, existente entre colaboradores e liderança das unidades orgânicas da instituição em análise, assenta no envolvimento e satisfação favorável no que respeita às relações líder-membro.

An ontological approach to competency management

Competency management is a very important part of a well-functioning organisation. Unfortunately competency descriptions are not uniformly specified nor defined across borders: National, sectorial or organisational, leading to an opaque competency description market with a multitude of competency frameworks and competency benchmarks. An ontology is a formalised description of a domain, which enables automated reasoning engines to be built which by utilising the interrelations between entities can make “intelligent” choices in different situations within the domain. Introducing formalised competency ontologies automated tools, such as skill gap analysis, training suggestion generation, job search and recruitment, can be developed, which compare and contrast different competency descriptions on the semantic level. The major problem with defining a common formalised ontology for competencies is that there are so many viewpoints of competencies and competency frameworks. Work within the TRACE project has focused on finding common trends within different competency frameworks in order to allow an intermediate competency description to be made, which other frameworks can reference. This research has shown that competencies can be divided up into “knowledge”, “skills” and what we call “others”. An ontology has been created based on this with a simple structure of different “kinds” of “knowledges” and “skills” using semantic interrelations to define the basic semantic structure of the ontology. A prototype tool for analysing a skill gap analysis has been developed. Personal profiles can be produced using the tool and a skill gap analysis is performed on a desired competency profile by using an ontologically based inference engine, which is able to list closest fit and possible proficiency gaps

Establishing a connection between knowledge transfer and innovation diffusion

Successful innovation diffusion process may well take the form of knowledge transfer process. Therefore, the primary objectives of this paper include: first, to evaluate the interrelations between transfer of knowledge and diffusion of innovation; and second to develop a model to establish a connection between the two. This has been achieved using a four-step approach. The first step of the approach is to assess and discuss the theories relating to knowledge transfer (KT) and innovation diffusion (ID). The second step focuses on developing basic models for KT and ID, based on the key theories surrounding these areas. A considerable amount of literature has been written on the association between knowledge management and innovation, the respective fields of KT and ID. The next step, therefore, explores the relationship between innovation and knowledge management in order to identify the connections between the latter, i.e. KT and ID. Finally, step four proposes and develops an integrated model for KT and ID. As the developed model suggests the sub-processes of knowledge transfer can be connected to the innovation diffusion process in several instances as discussed and illustrated in the paper.

Independence referendums: who should vote and who should be offered citizenship?

In this EUDO CITIZENSHIP Forum Debate, several authors consider the interrelations between eligibility criteria for participation in independence referendum (that may result in the creation of a new independent state) and the determination of putative citizenship ab initio (on day one) of such a state. The kick-off contribution argues for resemblance of an independence referendum franchise and of the initial determination of the citizenry, critically appraising the incongruence between the franchise for the 18 September 2014 Scottish independence referendum, and the blueprint for Scottish citizenship ab initio put forward by the Scottish Government in its 'Scotland's Future' White Paper. Contributors to this debate come from divergent disciplines (law, political science, sociology, philosophy). They reflect on and contest the above claims, both generally and in relation to regional settings including (in addition to Scotland) Catalonia/Spain, Flanders/Belgium, Quebec/Canada, Post-Yugoslavia and Puerto-Rico/USA.

Psychological contracts and independent sales contractors: an examination of the predictors of contractor-level outcomes

Over the past decade, the independent sales contractor (ISC) has emerged as both an important distribution channel and a management challenge. This study makes two contributions to this evolving field. First, it explores the interrelations of the psychological contract with sales performance, voluntary turnover and organisational advocacy of ISCs, which have hitherto been largely unexplored. Second, it examines differences between high- and low-performing sales contractors on these linkages, due to findings in the literature that a small number of sales contractors often achieve a majority of sales. Based on survey data as well as 7 years of contractor-level data related to sales performance and voluntary turnover (n = 189), results indicate that psychological contract fulfilment and perceived dependency are important determinants of subsequent sales performance, voluntary turnover and organisational advocacy, with significant differences reported between high- and low-performing ISCs. A notable finding pertinent for sales managers responsible for managing ISCs is that high-performing sales contractors are motivated by psychological contract fulfilment and a low perception of dependency, while low-performing sales contractors are more likely to act as advocates for the firm due to perceived dependency, but may concurrently engage in organisational advocacy as a means to leave the firm.

Evaluating nitrogen utilization efficiency of nonpregnant dry cows offered solely fresh cut grass at maintenance levels

The present study aimed to identify key parameters influencing N utilization and develop prediction equations for manure N output (MN), feces N output (FN), and urine N output (UN). Data were obtained under a series of digestibility trials with nonpregnant dry cows fed fresh grass at maintenance level. Grass was cut from 8 different ryegrass swards measured from early to late maturity in 2007 and 2008 (2 primary growth, 3 first regrowth, and 3 second regrowth) and from 2 primary growth early maturity swards in 2009. Each grass was offered to a group of 4 cows and 2 groups were used in each of the 8 swards in 2007 and 2008 for daily measurements over 6 wk; the first group (first 3 wk) and the second group (last 3 wk) assessed early and late maturity grass, respectively. Average values of continuous 3-d data of N intake (NI) and output for individual cows ( = 464) and grass nutrient contents ( = 116) were used in the statistical analysis. Grass N content was positively related to GE and ME contents but negatively related to grass water-soluble carbohydrates (WSC), NDF, and ADF contents ( < 0.01), indicating that accounting for nutrient interrelations is a crucial aspect of N mitigation. Significantly greater ratios of UN:FN, UN:MN, and UN:NI were found with increased grass WSC contents and ratios of N:WSC, N:digestible OM in total DM (DOMD), and N:ME ( < 0.01). Greater NI, animal BW, and grass N contents and lower grass WSC, NDF, ADF, DOMD, and ME concentrations were significantly associated with greater MN, FN, and UN ( < 0.05). The present study highlighted that using grass lower in N and greater in fermentable energy in animals fed solely fresh grass at maintenance level can improve N utilization, reduce N outputs, and shift part of N excretion toward feces rather than urine. These outcomes are highly desirable in mitigation strategies to reduce nitrous oxide emissions from livestock. Equations predicting N output from BW and grass N content explained a similar amount of variability as using NI and grass chemical composition (excluding DOMD and ME), implying that parameters easily measurable in practice could be used for estimating N outputs. In a research environment, where grass DOMD and ME are likely to be available, their use to predict N outputs is highly recommended because they strongly improved of the equations in the current study.

Children's Vocabulary Development : The role of parental input, vocabulary composition and early communicative skills

The aim of this thesis is to examine the early vocabulary development of a sample of Swedish children in relation to parental input and early communicative skills. Three studies are situated in an overall description of early language development in children. The data analyzed in the thesis was collected within a larger project at Stockholm University (SPRINT- “Effects of enhanced parental input on young children’s vocabulary development and subsequent literacy development” [VR 2008-5094]). Data analysis was based on parental report via SECDI, the Swedish version of the MacArthur-Bates Communicative Development Inventories, and audio recordings. One study examined parental verbal interaction characteristics in three groups of children with varying vocabulary size at 18 months. The stability of vocabulary development at 18 and 24 months was investigated in a larger study, with focus on children’s vocabulary composition and grammatical abilities. The third study examined interrelations among early gestures, receptive and productive vocabulary, and grammar measured with M3L, i.e. three longest utterances, from 12 to 30 months. Overall results of the thesis highlight the importance of early language development. Variability in different characteristics in parental input is associated with variability in child vocabulary size. Children with large early vocabularies exhibit the most stability in vocabulary composition and the earliest grammatical development. Children’s vocabulary composition may reflect individual stylistic variation. Use of early gestures is associated differentially with receptive and productive vocabulary. Results of the thesis have implications for parents, child- and healthcare personnel, as well as researchers and educational practitioners. The results underscore the importance of high quality in adult-child interaction, with rich input fine-tuned to children’s developmental levels and age, together with high awareness of early language development.

O estilo gerencial do executivo público catarinense

The purpose of this study was make an utterance of the managerial style of the public executive from Santa Catarina and compare it with public executives from Minas Gerais and United States, considering their capacity in giving and receiving feedback and their opening or auto-expositions in the interrelations with subordinates. It began with a review of the literature about functions and managerial style from several contributions that exist in the theory of the organizations. The theoric countersignement used in this essay was stablished in “Johari’s Window”, of Luft, that brought the possibility of the analysis of the interpersonal relations, considering the feedback variants and opening. The research is descriptive and still comparative, being applied to public executives from Santa Catarina, between the occupants of the first and the second hierarchic rungs. The instrument used was the questionnaire “Personel Relations Surwey”, of John Hall and Martha Williams, the same was applied at the researches that had been made in Minas Gerais and in United States. It was evident, by the statistic analysis in coherence with the theoric model, several conclusions, among them we detach: a) The unexistence of a standart managerial style between public executives from Santa Catarina; b) Executives from this state use more feedback than executives from Minas Gerais and the same as north-americans; c) The executives from Santa Catarina have more opening (overture) than mineiros and north-americans; d) Some personel variants interfere in the managerial style of the public executive from Santa Catarina.

Literatura infantil : uma abordagem das qualidades sensíveis e inteligíveis da leitura imagética na escola

Esta dissertação discute a leitura de textos imagéticos a partir da perspectiva da educação e da semiótica visual, tratando das articulações e relações entre os elementos constitutivos da imagem em livros de literatura infantil sem texto verbal. A investigação busca revelar, na complexidade das relações existentes entre elementos estruturantes das imagens nos livros O caminho do caracol e Cena de rua, o sentido que se inscreve no texto e a possibilidade da sua leitura no meio escolar. As obras literárias para a infância veiculam a linguagem visual em junção com a verbal e propiciam experiências sensíveis e inteligíveis. A partir da teoria semiótica greimasiana, aplicando instrumentos de análise do percurso gerativo de sentido, a pesquisa demonstra que o texto imagético é estruturado por diferentes níveis de complexidade, impondo um modo de ler específico. A identificação, descrição, classificação, bem como as relações entre as categorias, nas suas dimensões cromática, eidética e topológica, levam à constatação que as qualidades plásticas da imagem organizam sistemas de linguagem, reunindo solidariamente o plano da expressão e do conteúdo, criam estruturas e geram efeitos de sentido. A imagem, então, constitui-se como objeto de significação e a ilustração presente no livro de literatura infantil, ao ser tratada como texto lisível, torna-se objeto de leitura. A complexidade desse tipo de texto aponta a necessidade da formação específica de professores para explorar a leitura escolar das linguagens visuais.
