Evaluating leadership development using the Most Significant Change technique

Course evaluations are now a serious matter for universities trying to meet stakeholder needs and expectations, quality assurance, improvements and strategic decision making. Typically, students are invited to participate in surveys on how well the design and delivery aspects meet predetermined learning objectives, quality of teaching, and the types of improvements needed for future deliveries. We used the Most Significant Change technique to gather data on the impact of a leadership course on 18 Pacific Islanders who completed a Master of Education (Educational Leadership). Participants' views highlighted impacts that were of significance to the students and their workplaces. The findings demonstrate that the Most Significant Change technique offers a more comprehensive understanding of the impact of leadership development courses.

Aspect-based model of user experience

Traditional HCI design and evaluation methods merely focus on functional and usability aspects of a product. Although these aspects are important, they do not guarantee product’s success, especially the consumer product. Many consumer products are now part of user’s everyday activities – that support fun, pleasure, entertainment, etc. Secondly, in today’s consumer market many of the products have become similar in terms of their technology, functionality, price and quality. In response, many companies have started designing products with added emotional and experiential values. This has challenged designer’s to explore and visualize directions in product design field that could evoke intended and desired experiences amongst its users. Subjective product qualities such as fun, pleasure, entertainment, etc. are not the part of a product, but they are better thought of as the outcome of user’s interaction with the product...

Recent advances in modeling the vulnerability of transportation networks

It is well known that, for major infrastructure networks such as electricity, gas, railway, road, and urban water networks, disruptions at one point have a knock on effect throughout the network. There is an impressive amount of individual research projects examining the vulnerability of critical infrastructure network. However, there is little understanding of the totality of the contribution made by these projects and their interrelationships. This makes their review a difficult process for both new and existing researchers in the field. To address this issue, a two-step literature review process is used, to provide an overview of the vulnerability of the transportation network in terms of four main themes - research objective, transportation mode, disruption scenario and vulnerability indicator –involving the analysis of related articles from 2001 to 2013. Two limitations of existing research are identified: (1) the limited amount of studies relating to multi-layer transportation network vulnerability analysis, and (2) the lack of evaluation methods to explore the relationship between structure vulnerability and dynamical functional vulnerability. In addition to indicating that more attention needs to be paid to these two aspects in future, the analysis provides a new avenue for the discovery of knowledge, as well as an improved understanding of transportation network vulnerability.

Patient perspectives of using a web based intervention program for patients with type 2 diabetes and acute coronary syndrome

Introduction Research highlights patients with dual diagnoses of type 2 diabetes and acute coronary syndrome (ACS) have higher readmission rates and poorer health outcomes than patients with singular chronic conditions. Despite this, there is a lack of education programs targeted for this dual diagnosis population to improve self-management and decrease negative health outcomes. There is evidence to suggest that internet based interventions may improve health outcomes for patients with singular chronic conditions, however there is a need to develop an evidence base for ACS patients with comorbid diabetes. There is a growing awareness of the importance of a participatory model in developing effective online interventions. That is, internet interventions are more effective if end users’ perceptions of the intervention are incorporated in their final development prior to testing in large scale trials. Objectives This study investigated patients’ perspectives of the web-based intervention designed to promote self-management of the dual conditions in order to refine the intervention prior to clinical trial evaluation. Methods An interpretive approach with thematic analysis was used to obtain deeper understanding regarding participants’ experience when using web-application interventions for patients with ACS and type 2 diabetes. Semi-structured interviews were undertaken on a purposive sample of 30 patients meeting strict inclusion and exclusion criteria to obtain their perspectives on the program. Results Preliminary results indicate patients with dual diagnoses express more complex needs than those with a singular condition. Participants express a positive experience with the proposed internet intervention and emerging themes include that the web page is seen as easy to use and comforting as a support, in that patients know they are not alone. Further results will be reported as they become available. Conclusion The results indicate potential for patient acceptability of the newly developed internet intervention for patients with ACS and comorbid diabetes. Incorporation of patient perspectives into the final development of the intervention is likely to maximise successful outcomes of any future trials that utilise this intervention. Future quantitative evaluation of the effectiveness of the intervention is being planned.

Physical characterization of plastic surfaces in wearing and cleanability research

Plastic surfaces are a group of materials used for many purposes. The present study was focused on methods for investigation of surface topography, wearing and cleanability of polyvinyl chloride (PVC) model surfaces and industrial plastic surfaces. Contact profilometry, scanning electron microscopy (SEM) and atomic force microscopy (AFM) are powerful methods for studying the topography of plastic surfaces. Although they have their own limitations, they are together an effective tool providing useful information on surface topography, especially when studying laboratory-made PVC model surfaces with known chemical compositions and structures. All examined laboratory-made PVC plastic surfaces examined in this work could be considered as smooth according to both AFM and profilometer measurements because height differences are in the nanoscale on every surface. Industrial plastic surfaces are a complex group of materials because of their chemical and topographical heterogeneity, but they are nevertheless important reference materials when developing cleaning and wearing methods. According to the results of this study the Soiling and Wearing Drum and the Frick-Taber methods are very useful when simulating three-body wearing of plastic surfaces. Both the investigated wearing methods can be used to compare the wearing of different plastic materials using appropriate evaluation methods of wearing and industrial use. In this study, physical methods were developed and adapted from other fields of material research to cleanability studies. The thesis focuses on the methodology for investigating the cleanability of plastic surfaces under realistic conditions, where surface topography and the effect of wear cleanability were among the major topics. A colorimetric method proved to be suitable for examining the cleanability of the industrial plastic surfaces. The results were utilized to evaluate the relationship between cleanability and the surface properties of plastic surfaces. The devices and methods used in the work can be utilized both in material research and product development.

Precipitation-induced runoff and leaching from milled peat mining mires by peat types : a comparative method for estimating the loading of water bodies during peat pruduction

Precipitation-induced runoff and leaching from milled peat mining mires by peat types: a comparative method for estimating the loading of water bodies during peat production. This research project in environmental geology has arisen out of an observed need to be able to predict more accurately the loading of watercourses with detrimental organic substances and nutrients from already existing and planned peat production areas, since the authorities capacity for insisting on such predictions covering the whole duration of peat production in connection with evaluations of environmental impact is at present highly limited. National and international decisions regarding monitoring of the condition of watercourses and their improvement and restoration require more sophisticated evaluation methods in order to be able to forecast watercourse loading and its environmental impacts at the stage of land-use planning and preparations for peat production.The present project thus set out from the premise that it would be possible on the basis of existing mire and peat data properties to construct estimates for the typical loading from production mires over the whole duration of their exploitation. Finland has some 10 million hectares of peatland, accounting for almost a third of its total area. Macroclimatic conditions have varied in the course of the Holocene growth and development of this peatland, and with them the habitats of the peat-forming plants. Temperatures and moisture conditions have played a significant role in determining the dominant species of mire plants growing there at any particular time, the resulting mire types and the accumulation and deposition of plant remains to form the peat. The above climatic, environmental and mire development factors, together with ditching, have contributed, and continue to contribute, to the existence of peat horizons that differ in their physical and chemical properties, leading to differences in material transport between peatlands in a natural state and mires that have been ditched or prepared for forestry and peat production. Watercourse loading from the ditching of mires or their use for peat production can have detrimental effects on river and lake environments and their recreational use, especially where oxygen-consuming organic solids and soluble organic substances and nutrients are concerned. It has not previously been possible, however, to estimate in advance the watercourse loading likely to arise from ditching and peat production on the basis of the characteristics of the peat in a mire, although earlier observations have indicated that watercourse loading from peat production can vary greatly and it has been suggested that differences in peat properties may be of significance in this. Sprinkling is used here in combination with simulations of conditions in a milled peat production area to determine the influence of the physical and chemical properties of milled peats in production mires on surface runoff into the drainage ditches and the concentrations of material in the runoff water. Sprinkling and extraction experiments were carried out on 25 samples of milled Carex (C) and Sphagnum (S) peat of humification grades H 2.5 8.5 with moisture content in the range 23.4 89% on commencement of the first sprinkling, which was followed by a second sprinkling 24 hours later. The water retention capacity of the peat was best, and surface runoff lowest, with Sphagnum and Carex peat samples of humification grades H 2.5 6 in the moisture content class 56 75%. On account of the hydrophobicity of dry peat, runoff increased in a fairly regular manner with drying of the sample from 55% to 24 30%. Runoff from the samples with an original moisture content over 55% increased by 63% in the second round of sprinkling relative to the first, as they had practically reached saturation point on the first occasion, while those with an original moisture content below 55% retained their high runoff in the second round, due to continued hydrophobicity. The well-humified samples (H 6.5 8.5) with a moisture content over 80% showed a low water retention capacity and high runoff in both rounds of sprinkling. Loading of the runoff water with suspended solids, total phosphorus and total nitrogen, and also the chemical oxygen demand (CODMn O2), varied greatly in the sprinkling experiment, depending on the peat type and degree of humification, but concentrations of the same substances in the two sprinklings were closely or moderately closely correlated and these correlations were significant. The concentrations of suspended solids in the runoff water observed in the simulations of a peat production area and the direct surface runoff from it into the drainage ditch system in response to rain (sprinkling intensity 1.27 mm/min) varied c. 60-fold between the degrees of humification in the case of the Carex peats and c. 150-fold for the Sphagnum peats, while chemical oxygen demand varied c. 30-fold and c. 50-fold, respectively, total phosphorus c. 60-fold and c. 66-fold, total nitrogen c. 65-fold and c. 195-fold and ammonium nitrogen c. 90-fold and c. 30-fold. The increases in concentrations in the runoff water were very closely correlated with increases in humification of the peat. The correlations of the concentrations measured in extraction experiments (48 h) with peat type and degree of humification corresponded to those observed in the sprinkler experiments. The resulting figures for the surface runoff from a peat production area into the drainage ditches simulated by means of sprinkling and material concentrations in the runoff water were combined with statistics on the mean extent of daily rainfall (0 67 mm) during the frost-free period of the year (May October) over an observation period of 30 years to yield typical annual loading figures (kg/ha) for suspended solids (SS), chemical oxygen demand of organic matter (CODmn O2), total phosphorus (tot. P) and total nitrogen (tot. N) entering the ditches with respect to milled Carex (C) and Sphagnum (S) peats of humification grades H 2.5 8.5. In order to calculate the loading of drainage ditches from a milled peat production mire with the aid of these annual comparative values (in kg/ha), information is required on the properties of the intended production mire and its peat. Once data are available on the area of the mire, its peat depth, peat types and their degrees of humification, dry matter content, calorific value and corresponding energy content, it is possible to produce mutually comparable estimates for individual mires with respect to the annual loading of the drainage ditch system and the surrounding watercourse for the whole service life of the production area, the duration of this service life, determinations of energy content and the amount of loading per unit of energy generated (kg/MWh). In the 8 mires in the Köyhäjoki basin, Central Ostrobothnia, taken as an example, the loading of suspended solids (SS) in the drainage ditch networks calculated on the basis of the typical values obtained here and existing mire and peat data and expressed per unit of energy generated varied between the mires and horizons in the range 0.9 16.5 kg/MWh. One of the aims of this work was to develop means of making better use of existing mire and peat data and the results of corings and other field investigations. In this respect combination of the typical loading values (kg/ha) obtained here for S, SC, CS and C peats and the various degrees of humification (H 2.5 8.5) with the above mire and peat data by means of a computer program for the acquisition and handling of such data would enable all the information currently available and that deposited in the system in the future to be used for defining watercourse loading estimates for mires and comparing them with the corresponding estimates of energy content. The intention behind this work has been to respond to the challenge facing the energy generation industry to find larger peat production areas that exert less loading on the environment and to that facing the environmental authorities to improve the means available for estimating watercourse loading from peat production and its environmental impacts in advance. The results conform well to the initial hypothesis and to the goals laid down for the research and should enable watercourse loading from existing and planned peat production to be evaluated better in the future and the resulting impacts to be taken into account when planning land use and energy generation. The advance loading information available in this way would be of value in the selection of individual peat production areas, the planning of their exploitation, the introduction of water protection measures and the planning of loading inspections, in order to achieve controlled peat production that pays due attention to environmental considerations.

Parametrized actor-critic algorithms for finite-horizon MDPs

Due to their non-stationarity, finite-horizon Markov decision processes (FH-MDPs) have one probability transition matrix per stage. Thus the curse of dimensionality affects FH-MDPs more severely than infinite-horizon MDPs. We propose two parametrized 'actor-critic' algorithms to compute optimal policies for FH-MDPs. Both algorithms use the two-timescale stochastic approximation technique, thus simultaneously performing gradient search in the parametrized policy space (the 'actor') on a slower timescale and learning the policy gradient (the 'critic') via a faster recursion. This is in contrast to methods where critic recursions learn the cost-to-go proper. We show w.p 1 convergence to a set with the necessary condition for constrained optima. The proposed parameterization is for FHMDPs with compact action sets, although certain exceptions can be handled. Further, a third algorithm for stochastic control of stopping time processes is presented. We explain why current policy evaluation methods do not work as critic to the proposed actor recursion. Simulation results from flow-control in communication networks attest to the performance advantages of all three algorithms.

Preparing health science students for interdisciplinary professional practice

In 2002, a number of lecturers from different clinical schools within the Faculty of Health Sciences at La Trobe University embarked on the development of a new interdisciplinary professional practice subject to be undertaken by all final-year undergraduate health science students. The subject was designed to better prepare students for their first professional appointment by introducing them to the concepts of interdisciplinary teamwork, the health care context, and the challenges and constraints that organizational contexts present. This report details the background of the project, the consultation and development that took place in the design of the subject, and implementation of the subject. The uniqueness of the project is explained by the number of disciplines involved, the online delivery, and the focus on a set of generic graduate attributes for health science students. It is hoped that students who have undertaken this subject will have a better understanding of the roles of other health professionals and the context in which they will be working by grappling with many real-life professional issues that they will face when they graduate and enter the workforce.

Viilin varahapatteen kehittäminen

Kirjallisuuskatsauksessa käsiteltiin viiliä hapanmaitotuotteena, viilin arviointimenetelmiä sekä viilihapatteissa käytettyjen hapatekantojen vaikutuksia maidossa ja niiden vuorovaikutuksia toisiinsa. Lisäksi pohdittiin viilihapatteiden bakteriofaageja, niiden ehkäisyä sekä solunsisäisiä että -ulkoisia faagiresistenssimekanismeja. Kokeellisessa osassa tutkittiin, onko nykyisten tuotantohapatteiden koostaminen yksittäiskannoista mahdollista, sekä koostettiin uusista Lactococcus lactis ssp. cremoris -kannoista varahapate. Hapatteiden käyttökelpoisuutta tutkittiin rakennemittauksin ja aistinvaraisin menetelmin. Varahapatteen faagikestävyyttä testattiin valmistamalla viiliä ja infektoimalla viilit faaginäytteillä. Hapatekannat viljeltiin fermentorissa, konsentroitiin sentrifugoimalla ja pakastettiin –75 °C:ssa. Hapatteet koostettiin noin 1 päivä ennen viilin valmistusta. Viilit arvioitiin aistinvaraisesti 3–6 hengen ryhmässä ja viileille tehtiin rakennemittaukset (kiinteys, sakeus ja koossapysyvyys) sekä kemialliset analyysit. Aistinvaraisen arvioinnin tulokset käsiteltiin tilastollisesti ja tulosten perusteella tehtiin uudet kantakombinaatiot ja viilit. Tuotantohapatekannoilla valmistetut viilit arvioitiin kolmitestillä (n = 10–11) ja uusilla kannoilla valmistetut viilit arvioitiin profiilitestillä (n = 8). Lisäksi viileille tehtiin rakennemittaukset ja kemialliset analyysit. Varahapatekoosteilla valmistettujen viilien pH laski 4,5:een faagin läsnäollessa 0–10 tunnin viiveellä verrattuna faagivapaisiin viileihin, kun taas tuotantohapatteet eivät hapantuneet faagin läsnäollessa. Aromintuottajat eivät kasvaneet viileissä kunnolla, kun hapate koostettiin yksittäiskannoista. Kolmitestissä ei erotettu nykyisillä tuotantohapatteilla valmistettua viiliä yksittäin koostetusta hapatteesta, eli hapatteita on mahdollista koostaa yksittäiskannoista. Varahapatteilla koostetut viilit poikkesivat profiilitestissä tuotantohapatteella koostetusta viilistä ulkonäkö- ja rakenneominaisuuksiltaan. Makuominaisuuksien suhteen ei viilien välille saatu eroa.

Sanailua, kynäilyä, intoilua ja epäilyä : Oppilaiden kirjoitustaito ja sen arvioiminen alkuopetuksessa

Objectives. In primary education the pupils form a basis for their writing skills. By assessing pupils writing skills the teacher gathers information about the development of their skills and notices possible learning disabilities. The assessment of writing skills requires both knowledge of different evaluation methods and the phonological system in Finnish language. The purpose of this study is to analyze the pupils writing skills and different assessment methods that help the teacher in writing evaluation. The pupils writing skills are viewed from spelling, composing and writing motivation s point of view. Methods. The research material consists of dictation exercises, written stories and writing motivation self-assessments of 19 pupils. Dictation exercises measured the spelling skills of pupils and they were written in the spring of the first grade and the autumn of the second grade. Dictation exercises were analyzed with two different methods: mistake analysis and word-structure analysis. Information of pupils spelling skills development was gathered by comparing their performance in autumn s dictation exercise to spring s dictation. Composing skills were measured with stories that the pupils wrote. Both the stories and the writing motivation s self-assessment were made in the autumn of the second grade. Composing skills were analyzed according to assessment criteria formed for this study. Results. The spelling skill of most of the pupils had developed from the first grade s spring to the second grade s autumn. The spelling skills of half of the pupils (N=9) had improved significantly. The composing skills of the pupils varied largely. Strongest part of the pupils composing skill was following instructions and the weakest part was the use of versatile vocabulary and clause structures. The girls outdid the boys in all segments of their composing skills. For most pupils their spelling skill reflected their composing skill: good spellers were also good story writers. The relation between writing motivation and general writing skill was not this simple: some pupils (N=5) writing motivation was much higher than what would have been expected based on their writing skills.

A performance-based framework for assessing liquefaction potential based on CPT data

This article describes a new performance-based approach for evaluating the return period of seismic soil liquefaction based on standard penetration test (SPT) and cone penetration test (CPT) data. The conventional liquefaction evaluation methods consider a single acceleration level and magnitude and these approaches fail to take into account the uncertainty in earthquake loading. The seismic hazard analysis based on the probabilistic method clearly shows that a particular acceleration value is being contributed by different magnitudes with varying probability. In the new method presented in this article, the entire range of ground shaking and the entire range of earthquake magnitude are considered and the liquefaction return period is evaluated based on the SPT and CPT data. This article explains the performance-based methodology for the liquefaction analysis – starting from probabilistic seismic hazard analysis (PSHA) for the evaluation of seismic hazard and the performance-based method to evaluate the liquefaction return period. A case study has been done for Bangalore, India, based on SPT data and converted CPT values. The comparison of results obtained from both the methods have been presented. In an area of 220 km2 in Bangalore city, the site class was assessed based on large number of borehole data and 58 Multi-channel analysis of surface wave survey. Using the site class and peak acceleration at rock depth from PSHA, the peak ground acceleration at the ground surface was estimated using probabilistic approach. The liquefaction analysis was done based on 450 borehole data obtained in the study area. The results of CPT match well with the results obtained from similar analysis with SPT data.

Psicólogos no labirinto das acusações: um estudo sobre a falsa denúncia de abuso sexual de pai contra filho no contexto da separação conjugal

Esta pesquisa teve por objetivo compreender como vêm sendo desempenhadas as práticas dos psicólogos que atuam em instituições de referência para atendimentos em casos de alegação de abuso sexual contra a criança. Para este fim, foram analisadas as declarações de dez pais acusados de abusar sexualmente dos filhos, por meio de questionário enviado e recebido por correio eletrônico. Este material permitiu apreender como os pais acusados compreendem a alegação de abuso sexual imputada contra eles e como operam no sentido de provar a inocência. Também foi possível registrar-lhes as impressões, dúvidas e sentimentos eliciados pelas acusações, o que deu subsídio à realização de entrevistas presenciais com psicólogos em etapa posterior. Foram realizadas entrevistas individuais semiestruturadas com cinco psicólogas de cinco instituições diferentes. As informações prestadas permitiram analisar aspectos como a abordagem teórica e os métodos de avaliação psicológica em casos de alegações de abuso sexual contra criança, incluindo uma discussão acerca da ocorrência de falsas denúncias de abuso sexual. A partir dessas informações, foi possível concluir que tais práticas tendem a privilegiar a palavra da criança, esta última, vista, por muitos, como aquela que deverá anunciar e qualificar a denúncia. Nesses termos, os pais são silenciados, enquanto as crianças são colocadas no lugar de responsáveis por decidir questões jurídicas em nome de seus direitos.

Avaliação de textos produzidos na aula de língua portuguesa: abordagens teóricas, questões didático-metodológicas e suas repercussões

Dentro do contexto da avaliação formativa, as práticas de correção dos textos produzidos devem ser entendidas não como medição da aprendizagem, mas principalmente como uma pesquisa, elas devem avaliar o aluno, o professor, o processo, as práticas enunciativas, a mediação, a escola e mesmo a família. Contudo, apesar de essa abordagem sobre a avaliação ser compatível com a concepção sócio-histórica e cognitiva da linguagem, que por sua vez é consoante com as orientações dos PCN de Língua Portuguesa, ela parece ainda se mostrar distante dos métodos adotados pelos professores. O objetivo geral desta dissertação é identificar as abordagens teóricas que subjazem aos métodos avaliativos de professores do ensino fundamental em relação à produção textual. Como objetivos específicos buscou-se (i) mapear os modelos de correção textual utilizado por esses professores a fim de oferecer um panorama sobre a realidade do ensino-aprendizagem da escrita; e (ii) organizar um material teórico capaz de embasar a prática avaliativa não apenas como um componente do ato pedagógico, mas também como componente simbólico da construção da imagem que o aluno tem sobre si e sobre sua capacidade de escrever. Trata-se de uma pesquisa qualitativa constituída por dois corpora, organizados a partir dos seguintes instrumentos: entrevista semiestruturada com sete professores que lecionam no terceiro e quarto ciclos do ensino fundamental em escolas públicas e/ou particulares; e textos escritos por alunos e corrigidos pelos mesmos professores-informantes. Constituindo um total de 35 documentos, cinco de cada professor e 3h48min de gravações transcritas. Para análise dos corpora optou-se pelo paradigma interpretativista, aliado ao paradigma indiciário, que busca olhar para além das recorrências, os dados episódicos, singulares, dados que possam ajudar a levantar hipóteses sobre uma realidade não observável por via direta. Em relação às abordagens teóricas, podem-se perceber três manifestações: (i) as que são focadas no sistema, observável quando o professor privilegia aspectos formais e quando suas marcações, ainda que busquem o aspecto discursivo, não são suficientes para que os alunos efetuem reflexões sobre o uso da língua; (ii) as que flutuam entre o estruturalismo e o sociointeracionismo, quando o professor, embora se utilize de práticas mais interacionais ainda deixa amplo espaço para correções formais; (iii) as que são eminentemente sociointeracionistas, em cujas marcas avaliativas pode-se observar respeito pela autoria, apreciação do texto, interferência significativa e convite à reflexão. Dessas práticas emergem dois papéis sociais dicotômicos assumidos pelo professor: o de revisor, que tem profunda relação com práticas avaliativas de medição, e o de leitor-avaliador, em que se pode perceber, além de métodos ligados ao sociointeracionismo e às práticas avaliativas formativas um outro aspecto singular: a afetividade. Para discorrer sobre cada um desses aspectos propostos, construiu-se uma revisão bibliográfica que buscou incorporar à discussão teórico-metodológica questões de ordem subjetivas, que orientam pensar a escrita não só sob seu aspecto sócio-histórico e cognitivo, mas também afetivo
