Getting familiar with the code is a challenging activity and therefore resource intensive. The larger the software code base, the larger the resource expenditure. We consider software development in the case of established software developed by mid to large mature teams. This thesis explores a new way of documenting code that could increase the productivity of software development. The method consists of creating small, dynamically-ordered sets of code locations called Landmarks. These sets called Journeys are significant for a feature. The landmarks contain documentation related to system behavior and qualitative system state information at the time when the software execution reaches the locations. This new type of documentation is very light and does not require extensive additional software systems for management. This information is stored, and shared in a seamless manner via the existing source control systems. An experiment was performed to gauge the efficiency of this method versus the current development practice. The difference of productivity between developers not using this approach versus developers benefiting from this approach was captured. The results could be qualitatively interpreted as pointing towards an overall increase of productivity for the participant developers using the new approach.

The purpose of this study is to make a fresh treatment of the question of Christian origins, especially the beginnings of New Testament christology, by a holistic approach. More specifically, this study will show that, contrary to the form-critical view, the christological themes of the New Testament originated with Jesus himself, not with the post-Easter church. The movement of exposition will be threefold. We shall begin with an investigation of the mentality of Second-Temple Judaism and, in particular, of the eschatologically-minded in this period (Part One): The main focus will be on the mode of scriptural reading of the eschatologically-minded. Next, we shall move to the Jesus tradition to show that Jesus perceived his eschatological ministry as climactic and definitive (Part Two): This analysis will show how deeply Jesus shared the eschatological mode of scriptural reading. Finally, based on the conclusions of the first two parts, we shall make an attempt to retrieve some significant aspects of Jesus' self understanding (Part Three): This study will contribute to the New Testament scholarship in several ways. First of all, it will confirm a recent discovery in respect to Jesus' aims. He aimed for the restoration of Israel, and the scriptural themes of election shaped his self-understanding. Second, our study will show that the form-critical description of Christian origins is in need of revision. Third, our study has a bearing on the study of the Gospel tradition. Scholars have regarded the citations from and allusions to the Scriptures in the Jesus tradition as an indication of secondary origin. Our investigation, however, yields no support to this assumption. Finally, our study will test the advantages of the holistic approach which we shall employ in the following pages. / Thesis / Doctor of Philosophy (PhD)

The study employed Ernest (2006) Theory of Semiotic Systems to investigate the use of and exposure to multiple representations in a 10th grade algebra II suburban high school class located in the southeastern region of the United States. The purpose of this exploratory case study (Yin, 2014) was to investigate the role of multiple representations in influencing and facilitating algebra II students’ conceptual understanding of piece-wise function, absolute-value functions, and quadratic functions. This study attempted to answer the following question: How does the use of and exposure to multiple representations influence algebra II students’ understanding and transfer of algebraic concepts? Furthermore, the following sub-questions assisted in developing a deeper understanding of the question: a) how does exposure to and use of multiple representations influence students’ identification of their pseudo-conceptual understanding of algebraic concepts?; b) how does exposure to and use of multiple representations influence students’ transition from pseudo-conceptual to conceptual understanding?; c) how does exposure to and use of multiple representations influence students’ transfer of their conceptual understanding to other related concepts? Understanding the notion of pseudo-conceptual understanding in algebra is significant in providing a tool for examining the veracity of algebra students’ conceptual understanding, where teachers have to consistently examine if students accurately understand the meanings of the mathematical signs that they are constantly using. The following data collection techniques were utilized: a) classroom observation, b) task based interviews, and c) study of documents. The unit of analysis was students’ verbal and written responses to task questions. Three themes emerged from the analysis of in this study: (a) re-imaging of conceptual understanding; (b) reflective approach to understanding and using mathematical signs; and (c) representational versatility in the use of mathematical signs. Findings from this study will contribute to the body of knowledge needed in research on understanding and assessing algebra students’ conceptual understanding of mathematics. In particular the findings from the study will contribute to the literature on understanding; the process of algebraic concepts knowledge acquisition, and the challenges that algebra students have with comprehension of algebraic concepts (Knuth, 2000: Zaslavsky et al., 2002).

This qualitative research seeks to improve our understanding of the relatively under-researched phenomenon of repeat teenage pregnancies, by exploring the underlying factors and meanings that teenagers ascribe to their pregnancies. The study uses a comparative approach to provide a comprehensive psychosocial and economic understanding of the factors leading to repeat teenage pregnancies. This is achieved by exploring both the diverse and similar experiences of two groups of teenagers within different socio-economic environments - one group of 26 respondents from the Caribbean islands of Jamaica and Barbados and the other group of 26 respondents from London. The research also capitalises on a unique opportunity to contextualize the welfare dependency/teenage pregnancy discourse. The behaviours, motivations, values and attitudes of young women who become repeatedly pregnant in a Welfare state such as England, are compared with those living in countries with limited state resources and few state benefits. The comparison shows that in the latter case, the lack of state intervention can have the disempowering impact of fostering dependency in many insidious forms. The findings demonstrate the very powerful influence that both intentional and hidden or masked factors can have on a young woman's decision to repeat a pregnancy. The intrinsic relationship between the personal driving forces of the young women and their repeated pregnancies is convincingly highlighted. These driving forces are accompanied by very strong and deep-rooted beliefs in the importance of motherhood and fertility, as well as anti-abortion views. When these factors are added to economic stringency, they provide the fuel for a young woman's journey into repeat pregnancies. The findings therefore caution against a reliance on a mechanistic understanding of both single and repeat teenage pregnancies and emphasise the fact that social, psychological, and emotional processes, as well as the economic influences, are also crucial to our understanding of repeat teenage pregnancies.
