Measuring and tracking quality factors in Free and Open Source Software projects

Free and Open Source Software (FOSS) has gained increased interest in the computer software industry, but assessing its quality remains a challenge. FOSS development is frequently carried out by globally distributed development teams, and all stages of development are publicly visible. Several product and process-level quality factors can be measured using the public data. This thesis presents a theoretical background for software quality and metrics and their application in a FOSS environment. Information available from FOSS projects in three information spaces are presented, and a quality model suitable for use in a FOSS context is constructed. The model includes both process and product quality metrics, and takes into account the tools and working methods commonly used in FOSS projects. A subset of the constructed quality model is applied to three FOSS projects, highlighting both theoretical and practical concerns in implementing automatic metric collection and analysis. The experiment shows that useful quality information can be extracted from the vast amount of data available. In particular, projects vary in their growth rate, complexity, modularity and team structure.

Lean Thinking in Software Development : Impacts of Kanban on Projects

The history of software development in a somewhat systematical way has been performed for half a century. Despite this time period, serious failures in software development projects still occur. The pertinent mission of software project management is to continuously achieve more and more successful projects. The application of agile software methods and more recently the integration of Lean practices contribute to this trend of continuous improvement in the software industry. One such area warranting proper empirical evidence is the operational efficiency of projects. In the field of software development, Kanban as a process management method has gained momentum recently, mostly due to its linkages to Lean thinking. However, only a few empirical studies investigate the impacts of Kanban on projects in that particular area. The aim of this doctoral thesis is to improve the understanding of how Kanban impacts on software projects. The research is carried out in the area of Lean thinking, which contains a variety of concepts including Kanban. This article-type thesis conducts a set of case studies expanded with the research strategy of quasi-controlled experiment. The data-gathering techniques of interviews, questionnaires, and different types of observations are used to study the case projects, and thereby to understand the impacts of Kanban on software development projects. The research papers of the thesis are refereed, international journal and conference publications. The results highlight new findings regarding the application of Kanban in the software context. The key findings of the thesis suggest that Kanban is applicable to software development. Despite its several benefits reported in this thesis, the empirical evidence implies that Kanban is not all-encompassing but requires additional practices to keep development projects performing appropriately. Implications for research are given, as well. In addition to these findings, the thesis contributes in the area of plan-driven software development by suggesting implications both for research and practitioners. As a conclusion, Kanban can benefit software development projects but additional practices would increase its potential for the projects.

The Walls of Agios Donatos Zervochoriou : A case study of a fortress in Thesprotia, northwestern Greece

The study deals with the dating and the function of the fortress of Agios Donatos, which is located in the Kokytos river valley in Thesprotia, northwestern Greece. To solve the dating problem one had to use parallels found in research literature, preferably within as close range as possible. As most of the fortresses within a close proximity had not been adequately published, one had to use parallels within a larger area, throughout the Hellenistic world. Archaeological material found in trial trenches on site was used when possible. To think of the function of the site one had to study the site itself and its relation to the environment, and to compare the situation with the parallels found in research literature, mostly different archaeological survey projects in Greece and Asia Minor. The fortress was built during a period ranging from the final decades of the fourth century down to the mid-third century BC. Most likely it was built during the first quarter of the third century, that is the reign of Pyrrhus of Epirus when the area experienced a boom in fortress building activity. The function of the site was most likely to protect a trade route from the major port in the area to the central areas of the valley and on to Kalamas river, which was the major route on to Macedon. In the end an appendix dealing with the other fortified sites in Thesprotia has been compiled.

The EU and Institutional Twinning in Morocco - An inquiry into the motives of cooperation through discourse ethics

This study examines Institutional Twinning in Morocco as a case of EU cooperation through the pragmatic, ethical and moral logics of reason in Jürgen Habermas’s discourse ethics. As a former accession tool, Twinning was introduced in 2004 for legal approximation in the context of the European Neighborhood Policy. Twinning is a unique instrument in development cooperation from a legal perspective. With its long historical and cultural ties to Europe, Morocco presents an interesting case study of this new form of cooperation. We will analyse motives behind the Twinning projects on illegal immigration, environment legislation and customs reform. As Twinning is a new policy instrument within the ENP context, there is relatively little preceding research, which, in itself, constitutes a reason to inquire into the subject. While introducing useful categories, the approaches discussing “normative power Europe” do not offer methodological tools precise enough to analyse the motives of the Twinning cooperation from a broad ethical standpoint. Helene Sjursen as well as Esther Barbé and Elisabeth Johansson-Nogués have elaborated on Jürgen Habermas’ discourse ethics in determining the extent of altruism in the ENP in general. Situating the analysis in the process-oriented framework of Critical Theory, discourse ethics provides the methodological framework for our research. The case studies reveal that the context in which they operate affects the pragmatic, ethical and moral aspirations of the actors. The utilitarian notion of profit maximization is quite pronounced both in terms of the number of Twinning projects in the economic sphere and the pragmatic logics of reason instrumental to security and trade-related issues. The historical background as well internal processes, however, contribute to defining areas of mutual interest to the actors as well as the motives Morocco and the EU sometimes described as the external projection of internal values. Through its different aspects, Twinning cooperation portrays the functioning of the pragmatic, ethical and moral logics of reason in international relations.

Collecting data from distributed FOSS projects

A key trait of Free and Open Source Software (FOSS) development is its distributed nature. Nevertheless, two project-level operations, the fork and the merge of program code, are among the least well understood events in the lifespan of a FOSS project. Some projects have explicitly adopted these operations as the primary means of concurrent development. In this study, we examine the effect of highly distributed software development, is found in the Linux kernel project, on collection and modelling of software development data. We find that distributed development calls for sophisticated temporal modelling techniques where several versions of the source code tree can exist at once. Attention must be turned towards the methods of quality assurance and peer review that projects employ to manage these parallel source trees. Our analysis indicates that two new metrics, fork rate and merge rate, could be useful for determining the role of distributed version control systems in FOSS projects. The study presents a preliminary data set consisting of version control and mailing list data.

Parasta ennen : Tasa-arvotyön projektitapaistuminen

This book is a study of equality work, that is, the activities which have involved the promotion of gender equality in Finland. The study focuses on the period when the public sector has become more market-oriented, and business-oriented thinking has penetrated activities that have not traditionally emphasised profit-making. I have asked about the kind of power relations that have led to equality work in Finland. In addition to marketisation, publicly funded projects, especially by the European Union, have permeated the public sector. I have analysed the effects this turn has had on the aims and activities of equality work. Despite marketisation, equality work has remained for decades, and problems related to equality have also been recognised. The question of agency is a central focus of this study. I have analysed the kind of agency that has been offered and possible in equality work. With my previous “equality project career”, I have also participated in the formation of my research subject. This study also represents a description of a researcher taking on the responsibility for being involved in the formation of her own research subject. The study data includes national and EU-level political and governmental documents as well as articles and other publications related to equality issues. The data also includes documents from 99 publicly funded equality projects. Notable research data have been drawn from research interviews with 30 people who have been engaged in equality work in different parts of Finland and who have also worked in publicly funded equality projects. As a research method, I have combined Foucault’s discourse analysis and genealogical analysis as well as deconstructive reading. Political and governmental programmes have called for equality work, such as teaching, training, research and other political influencing in order to promote the political interests of the welfare state. Alliance with the state offers the opportunity to accomplish professionalism and continuity. Although equality work has not achieved similar legitimisation compared to other public sector professions. Equality work has fulfilled the interests of welfare state despite current trends towards marketisation. Publicly and budgetary funded equality work has evolved into business-oriented projects in a situation where the project itself has become a new governing mechanism for society. To analyse this trend, I have developed the concept of projectisation. The concept refers to a form of power that has directed discussions of equality in order to be heard. On the other hand, projectisation has contributed to the visibility of problems related to equality while maintaining heteronormativity and hierarchical order of societal differences, especially of gender, as well as harnessing equality for market use, thereby becoming somewhat useful and productive. Equality has been labelled as women’s work and being something that women do and continuity of the equality work has required a complex form of competence. The persistence of problems concerning equality as well as co-operation between women and the “discourse virtuosity ” of equality work has also opened up opportunities for situational change. Key words: Equality work, project, projectisation, genealogical method, discourse analysis, deconstructive reading, heteronormativity, agency, discourse virtuosity.

How to design educational settings to promote collaborative inquiry: Pedagogical infrastructures for technology-enhanced progressive inquiry

Strategies of scientific, question-driven inquiry are stated to be important cultural practices that should be educated in schools and universities. The present study focuses on investigating multiple efforts to implement a model of Progressive Inquiry and related Web-based tools in primary, secondary and university level education, to develop guidelines for educators in promoting students collaborative inquiry practices with technology. The research consists of four studies. In Study I, the aims were to investigate how a human tutor contributed to the university students collaborative inquiry process through virtual forums, and how the influence of the tutoring activities is demonstrated in the students inquiry discourse. Study II examined an effort to implement technology-enhanced progressive inquiry as a distance working project in a middle school context. Study III examined multiple teachers' methods of organizing progressive inquiry projects in primary and secondary classrooms through a generic analysis framework. In Study IV, a design-based research effort consisting of four consecutive university courses, applying progressive inquiry pedagogy, was retrospectively re-analyzed in order to develop the generic design framework. The results indicate that appropriate teacher support for students collaborative inquiry efforts appears to include interplay between spontaneity and structure. Careful consideration should be given to content mastery, critical working strategies or essential knowledge practices that the inquiry approach is intended to promote. In particular, those elements in students activities should be structured and directed, which are central to the aim of Progressive Inquiry, but which the students do not recognize or demonstrate spontaneously, and which are usually not taken into account in existing pedagogical methods or educational conventions. Such elements are, e.g., productive co-construction activities; sustained engagement in improving produced ideas and explanations; critical reflection of the adopted inquiry practices, and sophisticated use of modern technology for knowledge work. Concerning the scaling-up of inquiry pedagogy, it was concluded that one individual teacher can also apply the principles of Progressive Inquiry in his or her own teaching in many innovative ways, even under various institutional constraints. The developed Pedagogical Infrastructure Framework enabled recognizing and examining some central features and their interplay in the designs of examined inquiry units. The framework may help to recognize and critically evaluate the invisible learning-cultural conventions in various educational settings and can mediate discussions about how to overcome or change them.

Tekstiilityötä ja matematiikkaa yhdistävän oppimateriaalin käyttökelpoisuus perusopetuksen yläluokilla

In this study the researcher wanted to show the observed connection of mathematics and textile work. To carry this out the researcher designed a textbook by herself for the upper secondary school in Tietoteollisuuden Naiset TiNA project at Helsinki University of Technology (URL:http://tina.tkk.fi/). The assignments were designed as additional teaching material to enhance and reinforce female students confidence in mathematics and in the management of their textile work. The research strategy applied action research, out of which two cycles two have been carried out. The first cycle consists of establishing the textbook and in the second cycle its usability is investigated. The third cycle is not included in this report. In the second cycle of the action research the data was collected from 15 teachers, five textile teachers, four mathematics teachers and six teachers of both subjects. They all got familiar with the textbook assignments and answered a questionnaire on the basis of their own teaching experience. The questionnaire was established by applying the theories of usability and teaching material assessment study. The data consisted of qualitative and quantitative information, which was analysed by content analysis with computer assisted table program to either qualitative or statistical description. According to the research results, the textbook assignments seamed to be applied better to mathematics lessons than textile work. The assignments pointed out, however, the clear interconnectedness of textile work and mathematics. Most of the assignments could be applied as such or as applications in the upper secondary school textile work and mathematics lessons. The textbook assignments were also applicable in different stages of the teaching process, e.g. as introduction, repetition or to support individual work or as group projects. In principle the textbook assignments were in well placed and designed in the correct level of difficulty. Negative findings concerned some too difficult assignments, lack of pupil motivation and unfamiliar form of task for the teacher. More clarity for some assignments was wished for and there was especially expressed a need for easy tasks and assignments in geometry. Assignments leading to the independent thinking of the pupil were additionally asked for. Two important improvements concerning the textbook attainability would be to get the assignments in html format over the Internet and to add a handicraft reference book.

Kymijoen vaelluskalojen nousureittien avaamisen kustannusten ja hyötyjen arviointi

The objective of this thesis is to evaluate different means of increasing natural reproduction of migratory fish, especially salmon, in the river Kymijoki. The original stocks of migratory fish in Kymijoki were lost by the 1950s because of hydropower plants and worsened quality of water in the river. Nowadays the salmon stocks is based on hatchery-reared fish, even though there is significant potential of natural smolt production in the river. The main problem in the natural reproduction is that the migratory fish cannot ascend to the reproduction areas above the Korkeakoski and Koivukoski hydropower plants. In this thesis alternative projects which aim to open these ascencion routes and their costs and benefits are evaluated. The method used in the evaluation is social cost-benefit analysis. The alternative projects evaluated in this thesis consist of projects that aim to change the flow patterns between the eastern branches of Kymijoki and projects that involve building a fish ladder. Also different combinations of these projects are considered. The objective of this thesis is to find the project that is the most profitable to execute; this evaluation can be done in comparing the net present values of the projects. In addition to this, a sensitivity analysis will be made on the parameter values that are most uncertain. We compare the net present values of the projects with the net present values of hatchery-reared smolt releases, so we can evaluate, if the projects or the smolt releases are more socially profitable in the long term. The results of this thesis indicate that especially the projects that involve building a fish ladder next to the Korkeakoski hydropower plant are the most socially profitable. If this fish ladder would be built, the natural reproduction of salmon in the Kymijoki river could become so extensive, that hatchery-reared smolt releases could even be stopped. The results of the sensivity analysis indicate that the net present values of the projects depend especially on the initial smolt survival rate of wild salmon and the functioning of the potential fish ladder in Korkeakoski. Also the changes of other parameter values influence the results of the cost-benefit analysis, but not as significantly. When the net present values of the projects and the smolt releases are compared, the results depend on which period of time is selected to count the average catches of reared salmon. If the average of the last 5 years catches is used in counting the net benefits of smolt releases, all the alternative projects are more profitable than the releases. When the average of the last 10 years is used, only building of the fish ladder in Korkeakoski and all the project combinations are more profitable than the smolt releases.

The link between foreign aid, public investment and economic growth

Länsimaat ovat rahoittaneet kehitysyhteistyöhankkeita jo lähes kuuden vuosikymmenen ajan, mutta kehitysavun tehokkuudesta ei olla edelleenkään päästy yksimielisyyteen. Yksi avunantajamaiden tapa vaikuttaa kehitysavun tehokkuuteen, eli avun vaikutukseen vastaanottajamaan taloudellisen kasvun kiihdyttäjänä, on sitoa ne julkisen sektorin infrastruktuurihankkeisiin. Joissain tapauksissa tämä vaikuttaa avun vastaanottajan käytökseen ja asenteisiin kehitysapua kohtaan. Tutkielmassa käsitellään kehitysavun tehokkuutta tilanteessa, jossa se on sidottu julkisen sektorin investointeihin kehitysmaassa. Tutkimus pohjaa Kalaitzidakisin ja Kalyvitisin (2008) malliin, jossa osa kehitysmaan julkisen talouden investoinneista rahoitetaan kehitysavulla. Seuraavaksi tarkastellaan ylijäämää tavoittelevan käyttäytymisen (rent- seeking) vaikutusta kehitysavun tehokkuuteen pohjaten Economidesin, Kalyvitisin ja Philippopoulosin (2008) malliin. Tutkielmassa referoidaan lisäksi tutkimuskysymystä sivuavia empiirisiä tutkimuksia, esitellään aluksi tavallisimmat kehitysyhteistyön muodot, sekä esitellään talousteoreettisia näkökulmia kehitysyhteistyön tehokkuuden määrittelylle. Tutkielma perustuu puhtaasti teoreettisiin malleihin ja niissä sovelletut menetelmät ovat matemaattisia. Tutkielmassa käsitellään ensin tapaus, jossa kehitysyhteistyöllä rahoitetaan julkisen sektorin investointihankkeita. Jossain tapauksissa kehitysavun kasvu lasku siirtää vastaanottajamaan kulutusta julkisista investoinneista kulutukseen, jolloin kehitysyhteistyövaroin osittain rahoitettujen hankkeiden koko pienenee, ja suhteellinen tehokkuus laskee. Seuraavaksi tarkastellaan tilannetta, jossa kehitysyhteistyövaroista vain osa päätyy hankkeen rahoittamiseen, ja todetaan, että kehitysavun tehokkuus ja vaikutus maan kansantulon kasvuun vähenee talouden toimijoiden ylijäämää tavoittelevan käyttäytymisen (mukaan lukien korruptio) myötä entisestään. Tämän tutkimuksen perusteella voidaan todeta, että kehitysapu vaikuttaa kehittyvän maan talouden kasvuun tapauksessa, jossa julkisia infrastruktuurihankkeita rahoitetaan osittain maan omin verovaroin ja osittain kehitysyhteistyövaroin. Ylijäämää tavoitteleva käyttäytyminen vaikuttaa kehitysavun tehokkuuteen negatiivistesti vähentäen kehitysavun positiivisia kasvuvaikutuksia.

Sosiaalityön ammattilaiset refleksiivisinä toimijoina : tutkimus erikoistumiskoulutuksesta Margaret Archerin teorian valossa

In Finland, specialized studies in social work (professional licentiate education) were begun in the year 2000. The education is targeted at experienced social workers and leads to a licentiate degree (a degree between master s and doctorate). In this study, the experiences of members of the first study cohort, specializing in social work with children and young people, are examined. The study s theoretical frame of reference is based on the morphogenetic approach, developed by British sociologist Margaret Archer. In it, the potential powers of both an agent as well as social and cultural structures are considered important and worth taking into account. Archer sees reflexivity, a person s ability to analyze herself/himself, as an essential starting point for agency. Thanks to reflexivity, people are able to engage in internal conversations , discuss the concerns that are important to them and form agential projects . In Archer s theory, the social structures and traits of the cultural system are seen as having potential power in relation to people s agential projects; these powers can enable but also restrain the realization of the projects. On the other hand, individuals can try to review the factors affecting their agential projects and find ways of action that facilitate them. The research task is to study the self-understanding of social work professionals in the 21st century, the issues and goals professionally important for them, as well as the contexts framing the realization of these goals. The research questions are as follows: 1) What kind of internal conversations, concerns and agential projects related to their work did the professionals taking part in licentiate education bring to light? 2) What kind of enabling and restraining factors can be identified in their situations? And 3) What kind of social structures and traits related to the cultural system are connected to these factors? The research material was collected by interviewing the students in different phases of their education. In 2001 and 2004 all members of the study group (n = 25) were interviewed. In 2007, 13 students took part. The themes of the internal conversations brought to light in the interviews were divided into four broad thematic categories: professional development, the position of children in social work, multiprofessional work and structural social work. In relation to these themes the students formed different kinds of agential projects. In addition, the study reveals several cultural and social structures that have enabled but also restrained the realization of the agential projects. These structures are linked, for example, to the relations between employees and employers, students and teachers, children and adults as well as between the representatives of different professions. Working conditions which social workers often consider weak are discussed as a focal issue related to many themes. These working conditions become evident, for example, in the great imbalance which exists between the professional tasks and the amount of time that social workers have for them. Difficult situations arise when social workers feel they cannot reach the goals that are professionally important to them because of the strict external conditions of the work.

Simulation and graph mining tools for improving gene mapping efficiency

Gene mapping is a systematic search for genes that affect observable characteristics of an organism. In this thesis we offer computational tools to improve the efficiency of (disease) gene-mapping efforts. In the first part of the thesis we propose an efficient simulation procedure for generating realistic genetical data from isolated populations. Simulated data is useful for evaluating hypothesised gene-mapping study designs and computational analysis tools. As an example of such evaluation, we demonstrate how a population-based study design can be a powerful alternative to traditional family-based designs in association-based gene-mapping projects. In the second part of the thesis we consider a prioritisation of a (typically large) set of putative disease-associated genes acquired from an initial gene-mapping analysis. Prioritisation is necessary to be able to focus on the most promising candidates. We show how to harness the current biomedical knowledge for the prioritisation task by integrating various publicly available biological databases into a weighted biological graph. We then demonstrate how to find and evaluate connections between entities, such as genes and diseases, from this unified schema by graph mining techniques. Finally, in the last part of the thesis, we define the concept of reliable subgraph and the corresponding subgraph extraction problem. Reliable subgraphs concisely describe strong and independent connections between two given vertices in a random graph, and hence they are especially useful for visualising such connections. We propose novel algorithms for extracting reliable subgraphs from large random graphs. The efficiency and scalability of the proposed graph mining methods are backed by extensive experiments on real data. While our application focus is in genetics, the concepts and algorithms can be applied to other domains as well. We demonstrate this generality by considering coauthor graphs in addition to biological graphs in the experiments.

Asukkaan Helsinki? : Tapaustutkimus vuorovaikutteisuudesta kaupunkisuunnittelussa

This study examines the interaction between inhabitants and urban planning. In addition to traditional methods of participation there can be seen an increasing need to find new channels and means to influence on one´s environment. Hearing of inhabitants during planning is hoped to decrease the amount of claims and this way to speed up the planning process. Discussion that emphasizes competitiveness and innovativeness in planning has brought out the role of inhabitants as selective consumers and end users. This extension of civil perspective completes the thought of participation in city planning and adds the pressure on developing the interaction and user orientation. The aim of the study is to point out the present situation of inhabitant´s participation and influencing in Helsinki. Helsinki City Planning Department opened a new information and exhibiotion hall called Laituri in 2008. Laituri provides the latest information about planning projects in Helsinki and temporary exhibitions as well as it operates as communication channel and information point for the department. In this study Laituri is examined as a case study of interaction between citizen and planner. The study is divided into two principal themes. The aim is to research action and interactivity at Laituri from the inhabitants´and planners´point of view. The qualitative study has inquiries, interview surveys and observation as research methods. Empiricial data of the study consists of three parts which complement each other: Laituri operational reseach, inquiry directed to the members of Laituri team and interviews of three experts. The aim is to find answers to questions like, does Laituri reach the citizens and will the opportunities to participate improve along Laituri. The study examines also how the local knowledge of inhabitants will come across to planners and further to planning. The study combines discussions of inhabitants´ influencing in Finnish society and science community. Cornerstones of the study are inhabitant participation, interaction and local knowledge in urban planning. The theory behind the study is communicative planning theory. In addition the theory consists of key concepts. The study introduces a concept of Inhabitant´s Helsinki, which reflects the inhabitant as customer-citizen who is an active product developer in participative urban planning. According to the research results the experts of Laituri and majority of inhabitants in Helsinki experience that the inhabitant´s possibilities to participate will improve along Laituri. However half of the citizens in Helsinki believe that local knowledge and ideas will only have minor impact on the final plan. According to city dwellers the present practise used by Helsinki City Planning Department supports only partially adequate interaction. The experts of Laituri experience that the role of Laituri is first of all forum of communication and discussion channel instead of effective local data collector. Based on the results the study introduces a model of inhabitant´s participation field. According to the model Laituri can be seen as phenomenom in Helsinki urban planning which has the elements of network municipality. The planner is more like diplomatic trend-setter and visionary. The inhabitant of Helsinki is an expert in city living and participative producer of local knowledge. Participation methods are increasingly segmented and tailored in every plan and project. The study argues that Inhabitant´s Helsinki is a pluralistic milieu in constant pressure for change. Therefore reaching the everyday life experiencies of inhabintants should be at higher degree in Helsinki City Planning Department´s operations.
