Käytettävyyssuunnittelun teoria ja käytäntö: Tapaustutkimus huonekalujen verkkokaupasta

Käytettävien ohjelmistojen suunnittelu tuo hyötyjä loppukäyttäjälle sekä muille sidosryhmille. Verkkokaupassa käytettävyys on elintärkeää, koska asiakkaat vaihtavat helposti seuraavalle sivustolle, mikäli he eivät löydä etsimäänsä. Tutkimusten mukaan käytettävyys vaikuttaa ostopäätöksen tekemiseen. Lisäksi käytettävyydellä on merkitystä asiakastyytyväisyyteen, joka taas vaikuttaa asiakasuskollisuuteen. Tässä tutkielmassa tutkittiin, miten käytettävyyttä suunnitellaan käytännössä verrattuna teoreettisiin suosituksiin. Tapaustutkimuksen kohteena oli huonekaluja myyvän kansainvälisen yrityksen verkkokaupan uudistamiseen tähtäävä projekti. Uudistamistarve nousi aikaisemman verkkokauppaversion puutteellisesta käytettävyydestä. Projekti toteutettiin ketterällä Scrum-menetelmällä. Empiirinen aineisto kerättiin puolistrukturoitujen haastattelujen avulla. Haastateltavat olivat käyttökokemuksen suunnitteluun osallistuvia henkilöitä. Haastattelujen teemat laadittiin teoreettisen aineiston pohjalta. Teoreettisessa osuudessa tutkittiin käytettävyyden suunnitteluun liittyviä periaatteita, prosessia ja menetelmiä. Aikaisemmasta tutkimuksesta löydettiin 12 periaatetta, jotka tukevat ja luonnehtivat käyttäjäkeskeistä suunnittelua. Käytettävyyttä suunnitellaan käyttäjäkeskeisen prosessin avulla. Eri prosessimallit pitivät keskeisinä asioina käyttökontekstin määrittelyä ja ymmärtämistä, mitattavia käytettävyysvaatimuksia, suunnitteluratkaisujen empiiristä arviointia sekä suunnitteluprosessin iteratiivisuutta. Lisäksi tarkasteltiin, mitä suunnittelumenetelmiä tutkijat ehdottavat käytettävyyden suunnitteluun ja mitä kyselytutkimusten perusteella todellisuudessa käytetään. Verkkokauppaprojektissa käytettävyyden suunnittelu erosi osittain teoreettisista suosituksista. Käyttökontekstitietoa ei ollut kaikilla projektiin osallistuvilla, eikä käytettävyysvaatimuksia ollut asetettu teorian tarkoittamalla tavalla. Yhtäläisyyksiäkin löytyi. Verkkokauppaprojektissa suunnitteluratkaisuja arvioitiin empiirisesti todellisten käyttäjien edustajien avulla. Suunnitteluprosessi oli iteratiivinen eli suunnitteluratkaisuja oltiin valmiita muuttamaan arvioinnin tuloksena. Tutkimuksen perusteella suositellaan, että verkkokauppaprojektissa parannettaisiin kommunikointia, koska käyttökontekstitieto ei saavuttanut kaikkia projektissa työskenteleviä. Teorian tulisi entisestään korostaa kommunikoinnin tärkeyttä. Tutkimuksen perusteella esitetään myös, että teoria ohjaisi paremmin vaatimusmäärittelyjen tekemiseen käytännössä.

THE USE OF THE EARLY WARNING INDICATOR REPORT TO IMPACT NINTH GRADE PROMOTION RATES IN A LARGE URBAN SCHOOL DISTRICT

Abstract The purpose of this study was to examine how four high schools used an Early Warning Indicator Report (EWIR) to improve ninth grade promotion rates. Ninth grade on-time promotion is an early predictor of a student’s likelihood to graduate (Bornsheuer, Polonyi, Andrews, Fore, & Onwuegbuzie, 2011; Leckrone & Griffith, 2006; Roderick, Kelley-Kemple, Johnson, & Beechum, 2014; Zvoch, 2006). The analysis revealed both similarities and differences in the ways that the four schools used the EWIR. The research took place in a large urban school district in the Mid-Atlantic. Sixteen participants from four high schools and the district’s central office voluntarily participated in face-to-face interviews. The researcher utilized a qualitative case study method to examine the implementation of the EWIR system in Wyatt School District. The interview data was transcribed and analyzed, along with district documents, to identify categories in this cross case analysis. Three primary themes emerged from the data: (1) targeted school structures for EWIR implementation, (2) the EWIR identified necessary supports for students, and (3) the central office support for school staff. The findings revealed the various ways that the target schools implemented the EWIR in their buildings and the level of support that they received from the central office that aided them in using the EWIR to improve ninth grade promotion rates. Based on the findings of this study, the researcher provided a number of key recommendations: (1) Districts should provide professional development to schools to ensure that schools have the support they need to implement the EWIR successfully; (2) There should be increased accountability from the central office for schools using the EWIR to identify impactful interventions for ninth graders; and (3) The district needs to assign dedicated central office staff to support the implementation of the EWIR in high schools across the district. As schools continue to face the challenge of improving ninth grade promotion rates, effective use of an Early Warning Indicator Report is recommended to provide school and district staff with data needed to impact overall student performance.

A case study of a district's intended and unintended results connected to the implementation of a required ninth-grade algebra 1 strategic initiative

There is a long history of debate around mathematics standards, reform efforts, and accountability. This research identified ways that national expectations and context drive local implementation of mathematics reform efforts and identified the external and internal factors that impact teachers’ acceptance or resistance to policy implementation at the local level. This research also adds to the body of knowledge about acceptance and resistance to policy implementation efforts. This case study involved the analysis of documents to provide a chronological perspective, assess the current state of the District’s mathematics reform, and determine the District’s readiness to implement the Common Core Curriculum. The school system in question has continued to struggle with meeting the needs of all students in Algebra 1. Therefore, the results of this case study will be useful to the District’s leaders as they include the compilation and analysis of a decade’s worth of data specific to Algebra 1.

Acessibilidade no ambiente escolar: reflexões com base no estudo de duas escolas municipais de Natal-RN

This work was originated through the results of the analysis of the services for the needs of people with disabilities that were permitted by the physical space of two schools of the municipality of Natal/RN. The general objective/goal was to subsidize the elaboration of alternatives for the planning of environments that could be used by any person. The study used the empirical research through the adoption of a multimethod approach including: (i) technical visits oriented by the NBR 9050, (ii) contact with users that have reduced mobility (visually impaired and wheelchair or crutch users) through escorted travels and interviews, and (iii) interview with school managers. The evidence from the research, even though with significant development of laws that guarantee people with disabilities their right to citizenship, the physical environment of our schools still present with many obstacles that prevent the mobility of people with disabilities which proves their lack of readiness to accommodate them. Therefore, the actions taken to address the accessibility has been the adoption of temporary solutions that makes the adaptation more difficult, adds obstacles and reinforces the undesirable segregation, however still very present in our society. Finally, there is the indication that in order to achieve the spatial configuration that promotes social contact and integration in between the persons with different physical status, it is necessary to completely comprehend the activities developed in each space, from the conception of the equipment to the individual learning needs, having in mind creating environments that stimulates the execution of the tasks in an independent manner without the assistance of others. The inclusion regarding attention to accessibility in the decision making process, directed to the arquitectural and urban project, would decrease the constant need to redevelop and adapt spaces, and should be definitely incorporated as an important component in the production of space

The impact of the MARINET initiative on the development of Marine Renewable Energy

Marine Renewable Energy Conversion systems comprise wave energy and tidal stream converters as well as offshore-wind turbines for electrical generation. These technologies are currently at different stages of development but are mostly at the pre-commercial stage and require research to be undertaken at a series of scales along the path to commercialization. However each of these technologies also needs specific research infrastructures in order to conduct this research. The aim of the MARINET initiative is to coordinate research and development at all scales (small models through to prototype scales, from laboratories through to open sea tests) and to allow access for researchers and developers to infrastructures which are not available universally in Europe, including test facilities for components such as power take-off systems, grid integration, moorings and environmental monitoring so as to ensure a focusing of activities in this area. The initiative offers researchers and developers access to 45 research facilities as well as to the associated network of expertise at all scales in Offshore Marine Renewable Energy technology research and development. The aim of this paper is to present this MARINET initiative that was started in 2011, bringing together a network of 29 partners spread across twelve countries. Details of the MARINET Transnational Access (TA) program are presented, for which over 260 applications were received throughout the 5 official calls for proposals. In particular, statistics on applications and completed projects are presented which provide an overview of the global development progress of the different offshore renewable energy conversion technologies at a European level. It also provides a good overview of the current research activity, as well as evidence of the requirement for specialised research facilities, in this burgeoning field.

Rôle de la collaboration famille-école dans la relation entre les caractéristiques sociodémographiques des familles et les difficultés de comportement des enfants de maternelle

Résumé : Les enfants de maternelle dont la préparation scolaire est limitée risquent de présenter des difficultés comportementales nuisibles à leur adaptation ultérieure. L’implication des parents à l’école, plus précisément la collaboration famille-école (CFE), peut représenter un facteur de protection favorisant l’adaptation de l’enfant tout au long de son parcours scolaire. Les écrits scientifiques suggèrent que la CFE jouerait un rôle important dans l’explication des difficultés de comportement, surtout auprès des enfants provenant de familles défavorisées. Cette étude porte sur le rôle de la CFE dans l’explication des difficultés de comportement intériorisé et extériorisé des enfants de maternelle qui présentaient des lacunes sur le plan de leur préparation scolaire. Les analyses de régression linéaire montrent que pour l’ensemble des familles de l’échantillon (n=47), plus il y a de communication entre le parent et l’enseignant, plus il y a présence de comportements extériorisés et intériorisés. Par contre, la CFE modère la relation entre un indice d’adversité constitué du cumul de cinq facteurs de risque sociodémographiques et les difficultés de comportement intériorisé. Ainsi, chez les familles défavorisées, une communication plus fréquente est associée à moins de comportements de type intériorisé.

Activity-based life cycle costing model for cost estimation and monitoring – Case: manned and autonomous dry bulk carrier

Recent developments in automation, robotics and artificial intelligence have given a push to a wider usage of these technologies in recent years, and nowadays, driverless transport systems are already state-of-the-art on certain legs of transportation. This has given a push for the maritime industry to join the advancement. The case organisation, AAWA initiative, is a joint industry-academia research consortium with the objective of developing readiness for the first commercial autonomous solutions, exploiting state-of-the-art autonomous and remote technology. The initiative develops both autonomous and remote operation technology for navigation, machinery, and all on-board operating systems. The aim of this study is to develop a model with which to estimate and forecast the operational costs, and thus enable comparisons between manned and autonomous cargo vessels. The building process of the model is also described and discussed. Furthermore, the model’s aim is to track and identify the critical success factors of the chosen ship design, and to enable monitoring and tracking of the incurred operational costs as the life cycle of the vessel progresses. The study adopts the constructive research approach, as the aim is to develop a construct to meet the needs of a case organisation. Data has been collected through discussions and meeting with consortium members and researchers, as well as through written and internal communications material. The model itself is built using activity-based life cycle costing, which enables both realistic cost estimation and forecasting, as well as the identification of critical success factors due to the process-orientation adopted from activity-based costing and the statistical nature of Monte Carlo simulation techniques. As the model was able to meet the multiple aims set for it, and the case organisation was satisfied with it, it could be argued that activity-based life cycle costing is the method with which to conduct cost estimation and forecasting in the case of autonomous cargo vessels. The model was able to perform the cost analysis and forecasting, as well as to trace the critical success factors. Later on, it also enabled, albeit hypothetically, monitoring and tracking of the incurred costs. By collecting costs this way, it was argued that the activity-based LCC model is able facilitate learning from and continuous improvement of the autonomous vessel. As with the building process of the model, an individual approach was chosen, while still using the implementation and model building steps presented in existing literature. This was due to two factors: the nature of the model and – perhaps even more importantly – the nature of the case organisation. Furthermore, the loosely organised network structure means that knowing the case organisation and its aims is of great importance when conducting a constructive research.

Exploring Health in Military Families: Does Continuity of Care Influence Patient Satisfaction?

To ensure mission-readiness for military members, support for their families is essential. Military family health and health care satisfaction has been a neglected area of study in this population. Satisfaction can be defined in terms of patient-, provider-, and practice-level factors and is influenced by continuity of care, which is often poor in transient military populations. Using a modified patient satisfaction survey, this study found that both the number of moves and assigned providers were significantly associated with continuity of care in military spouses. Further, continuity of care was a significant predictor of satisfaction with military health care.

Les coalitions comme stratégie de renouveau syndical : un cas aux Philippines

Cette recherche fait état de la crise du syndicalisme qui affecte la capacité d’action et l’efficacité des pratiques des organisations syndicales à travers le monde. Elle dresse un portrait complet des éléments de crise qu’elle décline sous les niveaux économique, politique et social. Cette recherche expose ainsi la nécessité d’un renouveau syndical pour porter précisément sur les coalitions, hétérogènes notamment, comme stratégie de renouveau syndical. Au plan analytique, elle évalue l’impact de l’identité et de la capacité organisationnelle d’une organisation syndicale aux Philippines sur son choix de se coaliser, mais aussi l’influence de ses objectifs et du contexte national dans lequel elle évolue. Les données empiriques pour mener cette étude proviennent principalement de près de 24 entrevues semi-dirigées, tenues auprès de représentants de l’une des plus grandes organisations syndicales des Philippines, de représentants d’organisations non syndicales alliées et de répondants externes à celle-ci. Premièrement, nos résultats montrent qu’une identité collective sociétale forte influence favorablement le choix de l’organisation syndicale étudiée de se coaliser. Elle confirme également le rôle essentiel de l’identité dans l’orientation de son action collective. Deuxièmement, nos résultats permettent de conclure qu’une capacité organisationnelle forte influence favorablement le choix de cette organisation syndicale de se coaliser, considérant qu’elle permet à celle-ci d’identifier les opportunités d’action, de mettre en œuvre de nouvelles stratégies et d’assurer la légitimité et la mobilisation des membres quant aux actions entreprises. De nos résultats ressort l’importance de l’éducation sur l’accroissement de la capacité organisationnelle et, particulièrement, sur la formation et le renforcement de l’identité collective de l’organisation syndicale étudiée. Plus encore, nos résultats exposent l’interaction entre les dimensions de l’identité et de la capacité organisationnelle : précisément, nous avons observé une relation de renforcement positif entre ces deux variables. Troisièmement, nos résultats mettent de l’avant l’interaction entre les différents niveaux de transformations résultantes de sa participation à différents types de coalitions. Ainsi dans le cas observé, l’obtention de transformation au plan intraorganisationnel permet à rebours d’obtenir des transformations au plan extraorganisationnel et vice-versa. Finalement, le contexte répressif des Philippines et les objectifs de l’organisation syndicale étudiée apparaissent favorables à son choix de se coaliser à différents niveaux (local, régional, national et international).

Conceptualisation, design and development of a primary school based child healthy weight intervention

INTRODUCTION: In common with much of the developed world, Scotland has a severe and well established problem with overweight and obesity in childhood with recent figures demonstrating that 31% of Scottish children aged 2-15 years old were overweight including obese in 2014. This problem is more pronounced in socioeconomically disadvantaged groups and in older children across all economic groups (Scottish Health Survey, 2014). Children who are overweight or obese are at increased risk of a number of adverse health outcomes in the short term and throughout their life course (Lobstein and Jackson-Leach, 2006). The Scottish Government tasked all Scottish Health Boards with developing and delivering child healthy weight interventions to clinically overweight or obese children in an attempt to address this health problem. It is therefore imperative to deliver high quality, affordable, appropriately targeted interventions which can make a sustained impact on children’s lifestyles, setting them up for life as healthy weight adults. This research aimed to inform the design, readiness for application and Health Board suitability of an effective primary school-based curricular child healthy weight intervention. METHODS: the process involved in conceptualising a child healthy weight intervention, developing the intervention, planning for implementation and subsequent evaluation was guided by the PRECEDE-PROCEED Model (Green and Kreuter, 2005) and the Intervention Mapping protocol (Lloyd et al. 2011). RESULTS: The outputs from each stage of the development process were used to formulate a child healthy weight intervention conceptual model then develop plans for delivery and evaluation. DISCUSSION: The Fit for School conceptual model developed through this process has the potential to theoretically modify energy balance related behaviours associated with unhealthy weight gain in childhood. It also has the potential to be delivered at a Health Board scale within current organisational restrictions.
