Las condiciones de interacción comunicativa en las técnicas lingüísticas de obtención de información y sus efectos en la elaboración discursiva sobre el cuerpo y la educación

El método de encuesta es un método de investigación de naturaleza lingüística y buena parte de las líneas de investigación elaboradas acerca de este método parecen haber obviado en buena medida esta característica. La relegación de la naturaleza lingüística del método de encuesta ha comportado un importante nivel de reificación de los elementos que se consideran implicados en él. Nos referimos fundamentalmente a las preguntas, a los entrevistadores y entrevistadoras, a las respuestas, a las personas encuestadas y a los propios instrumentos de las técnicas de investigación. Esta reificación ha transformado dichos elementos, en elementos objetivables y manipulables, y en cierta forma, desnudos de su principal característica: su significado y dimensión lingüística. Las repercusiones de este enfoque del método de encuesta han sido varias, entre ellas podemos destacar, por ejemplo, la reducción de lo lingüístico en los cuestionarios a meros enunciados casi métricos de preguntas, y la reducción de las respuestas a tan sólo marcas en diversas casillas. Este enfoque también ha propiciado que la figura del/de la entrevistador/a se convierta, por definición, en una fuente de sesgo, principalmente por sus características sociodemográficas, negándole una participación lingüística de interacción social en el método de encuesta. Igualmente, bajo esta perspectiva, la forma conversacional de la entrevista ha relegado a los cuestionarios a un mero intercambio de interrogaciones y monosílabos, o a un simple intercambio de papeles, olvidando precisamente que ni la entrevista es una conversación, ni los cuestionarios son elementos neutros en relación a la interacción lingüística de las personas implicadas en una situación de encuesta. Las hipótesis formuladas proponen en líneas generales, la recuperación de la naturaleza lingüística del método de encuesta, no tanto porque este método funcione a través de la palabra oral o escrita, como porque el lenguaje comporta una elaboración de significados compartidos en función de los mucho elementos que lo dimensionalizan. Entre estos elementos hemos destacado, en relación al método de encuesta, la propia situación de interacción condicionada por la técnica de investigación que se utilice (cuestionario autoadministrado, cuestionario entrevistado, entrevista), la persona encuestada, el/la interlocutor/a con el que la persona entra en contacto y con el que desarrol1ará la encuesta y el objeto sobre el cual va a ser preguntada la persona encuestada. En definitiva se trata de recuperar la importancia del contexto comunicativo y del "otro" simbólico en el proceso de obtención de información a través del método de encuesta. De forma más concreta las hipótesis tratan de poner de manifiesto la incidencia del objeto de interlocución, no tanto sobre los contenidos, sino sobre los procesos implicados en la interlocución. Igualmente las hipótesis sugieren que el modo de administración tiene efectos sobre los contenidos de respuesta, ya que los modos de administración son, en realidad, elementos contextuales de interlocución. Finalmente, las hipótesis tratan de otro elemento, el entrevistador o la entrevistadora sugiriendo que las interacciones de género, con sus puestas en juego de estereotipos, representaciones y prácticas tienen incidencia sobre los contenidos discursivos en función del contexto de interlocución y de la relevancia del tema. En este trabajo se han desarrollado dos investigaciones. En la primera investigación hemos tratado del tema del cuerpo y en la segunda de la educación. Se eligió el tema del cuerpo porque las hipótesis proponen la relevancia del contenido de interlocución en relación a la interacción comunicativa entre géneros, y consideramos que es una temática relativamente amenazante, ya que en la representación de lo público y lo privado pertenece más al dominio de lo privado que de lo público. La segunda investigación aborda el tema de la educación en contraste con la primera, es decir, su discurso pertenece al orden de lo público, de lo no amenazante y su interlocución está menos condicionada por las interacciones de género. Los resultados de las investigaciones nos permiten afirmar que la forma de administración no sólo es un medio de interrogación sino un contexto de interlocución, y que si bien el sexo como variable independiente tiene pocos efectos, el género está relacionado con los contenidos discursivos que se evidencian en la interlocución si existe una vinculación entre tema y contexto de género

Prediction leaching of potassium using the convective-dispersive and the convective log-normal transfer function models

There is increasing concern about soil enrichment with K+ and subsequent potential losses following long-term application of poor quality water to agricultural land. Different models are increasingly being used for predicting or analyzing water flow and chemical transport in soils and groundwater. The convective-dispersive equation (CDE) and the convective log-normal transfer function (CLT) models were fitted to the potassium (K+) leaching data. The CDE and CLT models produced equivalent goodness of fit. Simulated breakthrough curves for a range of CaCl2 concentration based on parameters of 15 mmol l(-1) CaCl2 were characterised by an early peak position associated with higher K+ concentration as the CaCl2 concentration used in leaching experiments decreased. In another method, the parameters estimated from 15 mmol l(-1) CaCl2 solution were used for all other CaCl2 concentrations, and the best value of retardation factor (R) was optimised for each data set. A better prediction was found. With decreasing CaCl2 concentration the value of R is required to be more than that measured (except for 10 mmol l(-1) CaCl2), if the estimated parameters of 15 mmol l(-1) CaCl2 are used. The two models suffer from the fact that they need to be calibrated against a data set, and some of their parameters are not measurable and cannot be determined independently.

Quantifying the residual creep life of polyester mooring ropes

This paper assesses the ARELIS (Assured Residual Life Span) method for estimating residual creep life of polyester rope used in deepwater mooring lines. A statistical model has been developed to quantify the uncertainties in the method, such as the scatter in creep rupture test data and load sharing between sub-ropes. This model can be used to determine the required test load, duration and number of ARELIS tests, in order to guarantee a minimum creep life for a mooring line at its service load. Creep rupture tests have been performed to provide input for the statistical model.

Infant-mother attachment and the growth of externalizing problems across the primary-school years

Background:  Some contend that attachment insecurity increases risk for the development of externalizing behavior problems in children. Method:  Latent-growth curve analyses were applied to data on 1,364 children from the NICHD Study of Early Child Care to evaluate the association between early attachment and teacher-rated externalizing problems across the primary-school years. Results:  Findings indicate that (a) both avoidant and disorganized attachment predict higher levels of externalizing problems but (b) that effects of disorganized attachment are moderated by family cumulative contextual risk, child gender and child age, with disorganized boys from risky social contexts manifesting increases in behavior problems over time. Conclusions:  These findings highlight the potentially conditional role of early attachment in children’s externalizing behavior problems and the need for further research evaluating causation and mediating mechanisms.

Goal-refinement appraisal of soft projects (GRASP)

Industrial projects are often complex and burdened with time pressures and a lack of information. The term 'soft-project' used here stands for projects where the ‘what’ and/or the ‘how’ is uncertain, which is often the experience in projects involving software intensive systems developments. This thesis intertwines the disciplines of project management and requirements engineering in a goal-oriented application of the maxim ‘keep all objectives satisfied’. It thus proposes a method for appraising projects. In this method, a goal-oriented analysis establishes a framework with which expert judgements are collected so as to construct a confidence profile in regard to the feasibility and adequacy of the project's planned outputs. It is hoped that this appraisal method will contribute to the activities of project ‘shaping’ and aligning stakeholders’ expectations whilst helping project managers appreciate what parts of their project can be progressed and what parts should be held pending further analysis. This thesis offers the following original contribution: an appreciation of appraisal in the project context; a goal-oriented confidence profiling technique; and: a technique to produce goal-refinement diagrams – referred to as Goal Sketching. Collectively these amount to a method for the ‘Goal Refinement Appraisal of Soft-Projects’ (GRASP). The validity of the GRASP method is shown for two projects. In the first it is used for shaping a business investigation project. This is done in real-time in the project. The second case is a retrospective study of an enterprise IT project. This case tests the effectiveness of forecasting project difficulty from an initial confidence profile.

Methodology To model the energy and greenhouse gas emissions of electronic software distributions

A new electronic software distribution (ESD) life cycle analysis (LCA)methodology and model structure were constructed to calculate energy consumption and greenhouse gas (GHG) emissions. In order to counteract the use of high level, top-down modeling efforts, and to increase result accuracy, a focus upon device details and data routes was taken. In order to compare ESD to a relevant physical distribution alternative,physical model boundaries and variables were described. The methodology was compiled from the analysis and operational data of a major online store which provides ESD and physical distribution options. The ESD method included the calculation of power consumption of data center server and networking devices. An in-depth method to calculate server efficiency and utilization was also included to account for virtualization and server efficiency features. Internet transfer power consumption was analyzed taking into account the number of data hops and networking devices used. The power consumed by online browsing and downloading was also factored into the model. The embedded CO2e of server and networking devices was proportioned to each ESD process. Three U.K.-based ESD scenarios were analyzed using the model which revealed potential CO2e savings of 83% when ESD was used over physical distribution. Results also highlighted the importance of server efficiency and utilization methods.

Twin experiments with the equivalent weights particle filter and HadCM3

This paper investigates the use of a particle filter for data assimilation with a full scale coupled ocean–atmosphere general circulation model. Synthetic twin experiments are performed to assess the performance of the equivalent weights filter in such a high-dimensional system. Artificial 2-dimensional sea surface temperature fields are used as observational data every day. Results are presented for different values of the free parameters in the method. Measures of the performance of the filter are root mean square errors, trajectories of individual variables in the model and rank histograms. Filter degeneracy is not observed and the performance of the filter is shown to depend on the ability to keep maximum spread in the ensemble.

Training on the use of a bespoke continuing professional development framework improves the quality of CPD records

BACKGROUND: Using continuing professional development (CPD) as part of the revalidation of pharmacy professionals has been proposed in the UK but not implemented. We developed a CPD Outcomes Framework (‘the framework’) for scoring CPD records, where the score range was -100 to +150 based on demonstrable relevance and impact of the CPD on practice. OBJECTIVE: This exploratory study aimed to test the outcome of training people to use the framework, through distance-learning material (active intervention), by comparing CPD scores before and after training. SETTING: Pharmacy professionals were recruited in the UK in Reading, Banbury, Southampton, Kingston-upon-Thames and Guildford in 2009. METHOD: We conducted a randomised, double-blinded, parallel-group, before and after study. The control group simply received information on new CPD requirements through the post; the active intervention group also received the framework and associated training. Altogether 48 participants (25 control, 23 active) completed the study. All participants submitted CPD records to the research team before and after receiving the posted resources. The records (n=226) were scored blindly by the researchers using the framework. A subgroup of CPD records (n=96) submitted first (before-stage) and rewritten (after-stage) were analysed separately. MAIN OUTCOME MEASURE: Scores for CPD records received before and after distributing group-dependent material through the post. RESULTS: Using a linear-regression model both analyses found an increase in CPD scores in favour of the active intervention group. For the complete set of records, the effect was a mean difference of 9.9 (95% CI = 0.4 to 19.3), p-value = 0.04. For the subgroup of rewritten records, the effect was a mean difference of 17.3 (95% CI = 5.6 to 28.9), p-value = 0.0048. CONCLUSION: The intervention improved participants’ CPD behaviour. Training pharmacy professionals to use the framework resulted in better CPD activities and CPD records, potentially helpful for revalidation of pharmacy professionals. IMPACT: • Using a bespoke Continuing Professional Development outcomes framework improves the value of pharmacy professionals’ CPD activities and CPD records, with the potential to improve patient care. • The CPD outcomes framework could be helpful to pharmacy professionals internationally who want to improve the quality of their CPD activities and CPD records. • Regulators and officials across Europe and beyond can assess the suitability of the CPD outcomes framework for use in pharmacy CPD and revalidation in their own setting.

Does fertilizer type and method of application cause significant differences in essential oil yield and composition in rosemary (Rosmarinus officinalis L.)?

Organic fertilizers based on seaweed extract potentially have beneficial effects on many crop plants. Herewe investigate the impact of organic fertilizer on Rosmarinus officinalis measured by both yield and oilquality. Plants grown in a temperature-controlled greenhouse with a natural photoperiod and a controlledirrigation system were treated with seaweed fertilizer and an inorganic fertilizer of matching mineralcomposition but with no organic content. Treatments were either by spraying on to the foliage or wateringdirect to the compost. The essential oil was extracted by hydro-distillation with a Clevenger apparatusand analysed by gas-chromatography mass-spectrometry (GC–MS) and NMR. The chemical composi-tions of the plants were compared, and qualitative differences were found between fertilizer treatmentsand application methods. Thus sprayed seaweed fertilizer showed a significantly higher percentage of�-pinene, �-phellandrene, �-terpinene (monoterpenes) and 3-methylenecycloheptene than other treat-ments. Italicene, �-bisabolol (sesquiterpenes), �-thujene, and E-isocitral (monoterpenes) occurred insignificantly higher percentages for plants watered with the seaweed extract. Each was significantly dif-ferent to the inorganic fertilizer and to controls. The seaweed treatments caused a significant increasein oil amount and leaf area as compared with both inorganic treatments and the control regardless ofapplication method.

Gamma transition intensity determination using multidetector coincidence data

This work describes two similar methods for calculating gamma transition intensities from multidetector coincidence measurements. In the first one, applicable to experiments where the angular correlation function is explicitly fitted, the normalization parameter from this fit is used to determine the gamma transition intensities. In the second, that can be used both in angular correlation or DCO measurements, the spectra obtained for all the detector pairs are summed up, in order to get the best detection statistics possible, and the analysis of the resulting bidimensional spectrum is used to calculate the transition intensities; in this method, the summation of data corresponding to different angles minimizes the influence of the angular correlation coefficient. Both methods are then tested in the calculation of intensities for well-known transitions from a (152)Eu standard source, as well as in the calculation of intensities obtained in beta-decay experiments with (193)Os and (155)Sm sources, yielding excellent results in all these cases.

MACHINE VISION FOR AUTOMATICVISUAL INSPECTION OF WOODENRAILWAY SLEEPERS USING UNSUPERVISED NEURAL NETWORKS

The motivation for this thesis work is the need for improving reliability of equipment and quality of service to railway passengers as well as a requirement for cost-effective and efficient condition maintenance management for rail transportation. This thesis work develops a fusion of various machine vision analysis methods to achieve high performance in automation of wooden rail track inspection.The condition monitoring in rail transport is done manually by a human operator where people rely on inference systems and assumptions to develop conclusions. The use of conditional monitoring allows maintenance to be scheduled, or other actions to be taken to avoid the consequences of failure, before the failure occurs. Manual or automated condition monitoring of materials in fields of public transportation like railway, aerial navigation, traffic safety, etc, where safety is of prior importance needs non-destructive testing (NDT).In general, wooden railway sleeper inspection is done manually by a human operator, by moving along the rail sleeper and gathering information by visual and sound analysis for examining the presence of cracks. Human inspectors working on lines visually inspect wooden rails to judge the quality of rail sleeper. In this project work the machine vision system is developed based on the manual visual analysis system, which uses digital cameras and image processing software to perform similar manual inspections. As the manual inspection requires much effort and is expected to be error prone sometimes and also appears difficult to discriminate even for a human operator by the frequent changes in inspected material. The machine vision system developed classifies the condition of material by examining individual pixels of images, processing them and attempting to develop conclusions with the assistance of knowledge bases and features.A pattern recognition approach is developed based on the methodological knowledge from manual procedure. The pattern recognition approach for this thesis work was developed and achieved by a non destructive testing method to identify the flaws in manually done condition monitoring of sleepers.In this method, a test vehicle is designed to capture sleeper images similar to visual inspection by human operator and the raw data for pattern recognition approach is provided from the captured images of the wooden sleepers. The data from the NDT method were further processed and appropriate features were extracted.The collection of data by the NDT method is to achieve high accuracy in reliable classification results. A key idea is to use the non supervised classifier based on the features extracted from the method to discriminate the condition of wooden sleepers in to either good or bad. Self organising map is used as classifier for the wooden sleeper classification.In order to achieve greater integration, the data collected by the machine vision system was made to interface with one another by a strategy called fusion. Data fusion was looked in at two different levels namely sensor-level fusion, feature- level fusion. As the goal was to reduce the accuracy of the human error on the rail sleeper classification as good or bad the results obtained by the feature-level fusion compared to that of the results of actual classification were satisfactory.

Bonusar : Mot ett långsiktigt tänkande

Background: The background explains different financial crises and the effect those crises had on the Swedish acquits regarding variable compensation. The resent discussion regarding variable compensation and the main problems with bonuses is also explained. Our theories for this essay is mainly based on the new directions from Finansinspektionen FFFS 2009:6,7 and stakeholder theory. Other theories used are agency theory, stewardship theory and economic man.Purpose: The purpose of this essay is to analyze the new directions for variable compensation and to investigate if these new directions can lead to a more long-term thinking for managers in banks. Method:We used semi-structured interviews with open questions for our survey. During the survey we conducted three personal interviews and one mail interview, respondents represented the stakeholder groups: stakeholder, stakewatcher and stakekeeper. Conclusion: During our survey we found that the directions from Finansinspektionen are still on an early stage and it has been hard to analyze their effects. But it has been shown that the banks experience some difficulty in identifying their risk takers. In our investigation we have found that the new directions can be a step towards a more long-term thinking but it requires the management to change the point of view regarding bonuses.

Hälsofrämjande arbete på SSAB i Borlänge : Hälsofrämjande processer i arbetslivet och ledarskapets betydelse för medarbetarens hälsa

Problem: Arbetsmiljön är viktig för människors välbefinnande. Hälsofrämjande faktorer antas inte bara styrka individens fysiska och psykiska hälsa, utan även företagets konkurrenskraft och lönsamhet. I uppsatsen undersöker vi hur företaget SSAB i Borlänge arbetar med hälsa genom att tillämpa ett hälsofrämjande perspektiv och utgå från teorin om Känslan av sammanhang (KASAM). Ledarskapsvärderingar har betydelse för medarbetares hälsa (Hanson, 2004) och vi undersöker vilken uppfattning ett antal chefer har om sina roller i det hälsofrämjande arbetet och deras syn på medarbetarundersökningen HälsoSAM som företagshälsovården på SSAB bedriver. Arbetsbelastningen på medarbetare och chefer ökar till följd av sparkrav, samtidigt som resurserna minskar (Gatu, 2003). Följden blir en större risk för ohälsa och ett sätt att minska sjukfrånvaron är att genomföra hälsofrämjande insatser (Prevent, 2001). Syfte: Syftet med studien är att utifrån ett hälsofrämjande perspektiv förklara vad chefer har för möjligheter att skapa förutsättningar för att främja medarbetarnas hälsa på SSAB i Borlänge. Metod: Den metod som ligger till grund för uppsatsen baseras på ett kvalitativt angreppssätt där semistrukturerade intervjuer samt litteraturstudier genomförts för att samla information. Analys: Ledarens beteende påverkar medarbetarna. Hög arbetsbelastning på SSABs chefer leder till lägre närvaro bland medarbetarna, vilket i sin tur ger sämre förutsättningar för att främja hälsan. HälsoSAM kartlägger medarbetarnas hälsoläge, både välbefinnande och arbetskapacitet. Resultaten är vägledande i det hälsofrämjande arbetet men överbelastning, tidsbrist och kunskapsbrist hos cheferna bidrar till att uppföljningen inte blir systematisk. För ett väl fungerande hälsoarbete krävs systematik. Slutsats: Hälsofrämjande processer i arbetslivet skapas genom balans mellan krav och resurser. På SSAB i Borlänge hindras hälsoarbetet av tidsbrist och kunskapsbrist hos cheferna. Kostnadsbesparingar påverkar hälsoarbetet negativt och systematiken i uppföljningsarbetet blir lidande. Ansvaret för hälsoarbetet läggs på företagshälsovården, men utan stöd från chefer blir inte hälsoarbetet en naturlig del i verksamheten. Det är viktigt att i rådande situation se vad främjande av hälsa kan ge tillbaka till företaget i både ekonomiska och kvalitativa termer. Insikt om detta ökar chefernas incitament att prioritera hälsofrämjande processer och organisera arbetet så att människor har förutsättningar att hantera, kontrollera och klara av sina uppgifter.
