The paper discusses results of a case study on the advantages applying pure aspect design patterns in the development of aspect-oriented (AO) application frameworks. By an AO application framework we mean a framework which, alongside with traditional object-oriented (OO) framework customization mechanisms, provides also abstract aspects as hot spots. We have tested the hypothesis that pure AO design patterns should promote the ease of designing collaborating abstract aspects representing hot spots. To this end, we studied the process of reworking of the OO simulation application framework into the AO framework. During this study, appropriate qualitative and quantitative data have been collected. The paper presents the generalization of the collected data and concludes that the above hypothesis has been proven.Objektinio karkaso pertvarkymas naudojant aspektinius projektavimo šablonusŽilvinas Vaira, Albertas Čaplinskas SummaryStraipsnyje pateikiami aspektinių projektavimo šablonų naudojimo aspektiniams dalykiniams karkasams projektuoti eksperimentinio tyrimo rezultatai. Aspektinis dalykinis karkasas – tai toks karkasas, kuriame greta tradicinių objektinio karkaso riemonių naudojami ir abstraktūs aspektai.

<p>GO is a new object-oriented programming language developed at Google by Rob Pike, Ken Thompson, and others. GO has the potential to become a major programming language. GO deserves an evaluation.  Design patterns document reoccurring problems and their solutions. The problems presented are programming language independent. Their solutions, however, are dependent on features programming languages provide. In this thesis we use design patterns to evaluate GO. We discuss GO features that help or hinder implementing design patterns, and present a pattern catalogue of all 23 Gang-of-Four design patterns with GO specific solutions. Furthermore, we present GoHotDraw, a GO port of the pattern dense drawing application framework JHotDraw. We discuss design and implementation differences between the two frameworks with regards to GO.</p>

Software quality models link internal attributes of programs with external quality characteristics. They help in understanding relationships among internal attributes and between internal attributes and quality characteristics. Object-oriented software quality models usually use metrics on classes (such as number of methods) or on relationships between classes (for example coupling) to measure internal attributes of programs. However, the quality of object-oriented programs does not depend on classes solely: it depends on the organisation of classes also. We propose an approach to build quality models using patterns to consider program architectures. We justify the use of patterns to build quality models, describe the advantages and limitations of such an approach, and introduce a first case study in building and in applying a quality model using design patterns on the JHotDraw, JUnit, and Lexi programs. We conclude on the advantages of using patterns to build software quality models and on the difficulty of doing so.

This case study explores how a leading charity, the British Heart Foundation (BHF), used research to ensure that the focus of its marketing and communications contributed to a story that people found engaging and were compelled to support. Amongst some staff, there was a view that the methodology of some of the BHF’s previous market research was not robust enough and that studies often lacked the quantitative data needed to develop marketing and communication strategies with confidence. Behavioural economics shows that there is usually a disconnect between what people say they will do and what they do in real life, the BHF wanted to develop a methodology that would interrogate this paradox. In doing so, it hoped to identify the areas of its work the public found most engaging and which would encourage people to support them. This insight would then be used to inform their new marketing communications plans. This note explains what the BHF learnt from involving explicit and implicit testing via a mix of qualitative and quantitative techniques.

We analyzed what happens to a nursing home chain when private equity takes over, with regard to strategy, financial performance, and resident well-being. We conducted a longitudinal (2000-2012) case study of a large nursing home chain that triangulated qualitative and quantitative data from 5 different data sources. Results show that private equity owners continued and reinforced several strategies that were already put in place before the takeover, including a focus on keeping staffing levels low; the new owners added restructuring, rebranding, and investment strategies such as establishing new companies, where the nursing home chain served as an essential “launch customer.”

Research demonstrates the critical need for transitional supportive housing (TSH) for survivors of domestic violence (Melbin, Sullivan, and Cain, 2003). However, the presence of such programs around the country is inconsistent, and where programs do exist, little consensus has been attained on what aspects of these programs are most beneficial for clients (Melbin et al., 2003). This paper presents initial descriptive data based on a program evaluation of a TSH facility located in a small rural town in the southern United States. Assessments at both the individual and program levels included gathering qualitative and quantitative data. We present data on the clients in the program as well as the support groups conducted from 2004 through spring 2006. Discussed in the conclusion are lessons learned and the next steps for greater program success.

Abstract Narrative study of religious lives has formed part of numerous projects at the Bielefeld Research Center for Biographical Studies in Contemporary Religion. An essential instrument in our designs, which mostly combine qualitative and quantitative methods, is the Faith Development Interview (FDI). In response to longstanding criticism its cognitive structural framework has been revised in respect of styles and schemata. The religious styles perspective examines the self as articulated in narratives and associates it with affectivity and emotion. This article gives an overview of our theoretical and methodological revisions, which take cognizance of current developments in lifespan developmental and clinical psychology such as attachment, mentalization and wisdom. We illustrate the implementation of these advances with a case study from our current study of ‘spirituality’,1 which we locate in the complex multi-method design, and outline the triangulation of qualitative and quantitative data.

Design patterns have become an important part of modern object-oriented design. It is necessary to evaluate and compare the effectiveness of different methods of pedagogical documentation in teaching design patterns. We compared patterns-style documentation with minimalist documentation. Patterns style disagrees with minimalism in that contextual information is not minimal — it usually contains information other than what needs to be done. The discoveries in this empirical study were two fold. First, the MANOVA (multivariate analyses of variance) shows that the effect of patterns-style documentation and minimalism are different. Second, we proposed a prediction model using a regression modeling technique. Considering these results, we formulate some guidelines for effective framework documentation by applying five of the design patterns within the Swing environment as our case study. Different documentation philosophies are better for different goals. For a simple task, use minimalist documentation. For a much more complex problem such involving five of the design patterns, our empirical results suggest using patterns-style documentation.

<p><em>The purpose of this study was to investigate the relationship between arts students’ English proficiency level and their self-efficacy. Many studies have proved that self-efficacy is a significant predictor of learning and achievement (Multon, Brown, &amp; Lent, 1991; Pajares, 1996, 1997; Schunk &amp; Pajares, 2005). Does this apply to arts students? Arts students spend most of their time practicing skills related to their professions. They have great confidence with what they were doing in their own fields, but they have to sacrifice the time that could be spent studying English. Therefore, are arts students’ self-efficacy correlated with their English proficiency levels? A total of sixty-eight students participated in this study. They were equally divided into two groups: High Proficiency Learners (HPL) and Low Proficiency Learners (LPL). The results show that there was no significant correlation between students’ English proficiency levels and their self-efficacy levels. The results did not support Bandura’s theory. However, the findings did indicate that although arts students’ English proficiency levels were poor, especially for students in the LPL group, they did believe that they had the ability to achieve a certain task. They did well in their professions but not in English. Further studies and more qualitative and quantitative data on arts students are needed.</em></p>

As pousadas são meios de hospedagem de pequeno porte, com um atendimento mais personalizado, e muitas vezes realizado diretamente pelos seus proprietários. Porém, independentemente do tamanho e da capacidade de um meio de hospedagem, ele pode investir em uma oferta de lazer, da mais simples, com algumas atividades, até a mais completa, com estrutura de equipamentos e serviços que buscam atender as expectativas de lazer dos hóspedes, contribuindo com isso para uma valoração de mercado. Esta pesquisa é um estudo de caso, com dados coletados em pesquisa bibliográfica, em artigos publicados sobre o tema, e entrevistas estruturadas, que através de dois métodos, quali-quantitativos, de coleta e análise de dados, teve como objetivo analisar a oferta de lazer das pousadas da Rota do Lambari, em Porto União, SC, os serviços e os equipamentos que estão sendo oferecidos aos hóspedes. Como resultado se observou uma oferta de lazer grande e variada na maioria delas, e uma oferta não focada somente no pescador, mas que atende a toda a família e outros hóspedes que não exercem a pesca. O lazer em pousadas de pesca: um estudo de caso na Rota do Lambari, Porto União (SC) ABSTRACT The lodges are small lodging facilities, with a more personalized service, and often performed directly by its owners. However, regardless of the size and capacity of a host resource, it can invest in a range of leisure, the simplest, with some activities to the fullest, with equipment structure and services that aim to meet the leisure expectations guests, a contributing factor to a market valuation. This research is a case study, with data collected in literature, in articles published on the subject, and structured interviews, which through two methods, qualitative and quantitative data collection and analysis, aimed to analyze the supply of leisure, hotels and Rota do Lambari, in the city of Porto União, SC, services and equipment that are being offered to guests. As a result it was observed offered a large and varied leisure in most of them, and not focused only offer the fisherman, but that caters to the whole family and other guests not engaged in fishing.
