The formalization of natural language contracts can make the prescriptions found in these contracts more precise, promoting the development of smart contracts, which are digitized forms of the documents where the monitoring and execution can be partially automated. Full formalization remains a difficult problem, and this thesis makes steps towards solving this challenge by focusing on a narrow sub-problem of formalizing contract refinements. We want to allow a contract author to customize a contract template, and automatically convert the resulting contract to a formal specification language called Symboleo, created specifically for the legal contract domain. The hope is that research towards partial formalization can be useful on its own, as well as useful towards the full formalization of contracts. The main questions addressed by this thesis involve asking what linguistic forms these refinements will take. Answering these questions involves both linguistic analysis and empirical analysis on a set of real contracts to construct a controlled natural language (CNL). This language is expressive and natural enough to be adopted by contract authors, and it is precise enough that it can reliably be converted into the proper formal specification. We also design a tool, SymboleoNLP, that demonstrates this functionality on realistic contracts. This involves ensuring that the contract author can input contract refinements that adhere to our CNL, and that the refinements are properly formalized with Symboleo. In addition to contributing an evidence-based CNL for contract refinements, this thesis also outlines a very clear methodology for constructing this CNL, which may need to go through iterations as requirements change and as the Symboleo language evolves. The SymboleoNLP tool is another contribution, and is designed for iterative improvement. We explore a number of potential areas where further NLP techniques may be integrated to improve performance, and the tool is designed for easy integration of these modules to adapt to emerging technologies and changing requirements.

While the transition back to work following maternity leave is a stage of a woman’s career that can have significant impact on the rest of her working life, this remains an under-researched topic. The current study examines mothers’ return to work experiences, with a specific focus on the downgrading to their jobs they encounter, perceived as demotions, which no previous study has pursued. Drawing from research investigating mothers’ psychological contracts and their turnover intentions, the current study examines the relationship between demotions, psychological contract violation and employment outcomes. Also of interest was whether psychological contract violation initiated a process of grieving, as mothers struggled to separate from their identities as valued employees. In-depth interviews were conducted with eight mothers. Mothers who perceived their restructured jobs as demotions experienced psychological contract violations in response, and also described emotions consistent with a process of grieving. However, not all mothers who experienced psychological contract breach or violation quit their jobs. Implications for working mothers and for future research are discussed. / Thesis / Master of Arts (MA)

Researchers know much about the use of contract (or adjunct) instructor faculty in academe, but little about contract instructors in civilian federal training agencies. No one has determined the effective administrative support of instructional delivery or the professional development needs of these federal agency contractors. The National Fire Academy's mission is to promote the professional development of those fire personnel engaged in fire suppression, fire prevention, and allied functions. Each year approximately 3000 resident students complete a variety of two week training programs. Approximately 500 contract instructors conduct most of these on-campus programs. These instructors have widely divergent expertise, instructional competence and teaching experience. The research questions were: 1. What are the problems, if any, that NFA contract instructors have had that have implications for effective program delivery?</li> 2. What are the administrative support services, if any, that should be provided to contract instructors in the areas of: A. Orientation of new instructors? B. Program delivery? C. Evaluation processes? D. Professional development?</li> 3. What other administrative support services, if any, would assist contract instructors in providing instructional services?</li> 4. What are the problems, if any, that Program Chairs have dealt with that have implications for effective program delivery? All 536 resident contract instructors received a questionnaire about their perception of their administrative support and professional development needs; 45% responded (n=245). Eight of the ten Academy Program Chairs, who oversee the contract instructors, were interviewed about the types of problems and solutions they have used in dealing with these personnel. Analysis used both quantitative and qualitative methods. This research had a three-fold purpose. First, the research could determine the elements of effective support of instructional delivery for the Academy's contract instructors. Second, the research could provide the basis to make policy recommendations of such elements for the Academy. Finally, the research sought to determine what was required to support the professional development of contract instructors in any training organization. The results indicated that the responding contract instructors had several administrative support needs and concerns including keeping program content current, providing new instructors with an orientation and an instructor handbook, gaining access to classroom supplies, and improving the availability of program evaluations. There was also strong interest in three professional development options: preferred admission to other NFA classes, on-site instructor conferences, and a newsletter. Generally, Program Chairs' responses were supportive of these needs. The recommendations included the implementation of a contract instructor career path and the use of a government and contractor "shared responsibility management model." / Ed. D.

Thesis advisor: Anant Nyshadham / Thesis advisor: Kit Baum / The dissertation consists of three independent explorations of labor market dynamics in developing countries. I first investigate how minimum wages affect employment and investment decision of firms in India and how they can lead to accelerated automation and offshoring. Then, I investigate how managers of garment production lines in India's largest ready-made garment producer establish informal agreements to deal with worker absenteeism shocks. Finally, I study how Indonesian households learn about their productivity in different sectors of the economy and show that they often spend years, if not decades, in sectors where they are less productive which depresses their earning potentials, but they converge to their most productive sector over time. In the first chapter, "Effect of Minimum Wages on Automation and Offshoring Decisions of Firms: Evidence from India", I study the effect of India's local minimum wages on the production structure of firms in the formal economy. I compile data on the country's numerous minimum wages which vary at the state, year, and industry level, and show that changes to these wages have important effects on firm-level capital investment and employment of different types of employees. The effects depend on the firms' ability to automate and offshore certain tasks. Using a difference-in-difference approach, I show that firms in the average industry, that is, firms in industries neither intensive in routine nor offshorable tasks, continue to invest in machinery and computers at a rate of 8% per year following a minimum wage hike. However, they substitute payroll workers with managers and contract workers less likely to be bound by the minimum wage. Firms in industries intensive in routine tasks that are easier to automate invest 6.1% more in machinery and 4% more in computers, at the expense of payroll workers. Firms in industries intensive in tasks easier to do remotely continue to invest in machinery and computers, but the rate of investment in computers falls by 6.2% following a minimum wage hike, and payroll worker employment falls as well. This suggests that some tasks that combine workers and computers, like data analysis, may be offshored. These results support the predictions of a task-based production model, and indicate that minimum wages have a strong effect on the structure of production at the firm level, leading some towards increased rates of automation and offshoring. In the second chapter, "Absenteeism, Productivity, and Relational Contracts Inside the Firm", joint with other researchers, we study relational contracts among managers using unique data that tracks transfers of workers across teams in Indian ready-made garment factories. We focus on how relational contracts help managers cope with worker absenteeism shocks, which are frequent, often large, weakly correlated across teams, and which substantially reduce team productivity. Together these facts imply gains from sharing workers. We show that managers respond to shocks by lending and borrowing workers in a manner consistent with relational contracting, but many potentially beneficial transfers are unrealized. This is because managers' primary relationships are with a very small subset of potential partners. A borrowing event study around main trading partners' separations from the firm reinforces the importance of relationships. We show robustness to excluding worker moves least likely to reflect relational borrowing responses to idiosyncratic absenteeism shocks. Counterfactual simulations reveal large gains to reducing costs associated with forming and maintaining additional relationships among managers. In the last chapter, "Learning, Selection, and the Misallocation of Households Across Sectors", joint with other researchers, we study the role of labor misallocation (i.e., suboptimal sorting of households across sectors) in explaining low productivity in developing countries. We estimate a generalized earnings equation with dynamic correlated random coefficients, allowing households to learn about their relative productivity across the agricultural and non-agricultural sectors. Estimates show that households sort across sectors on comparative advantage, but learn and converge slowly over time, with many households spending substantial time in a suboptimal sector. Roughly 33% of households are misallocated to start, earning 64% less on average than they could have if they were properly sorted across sectors. Our approach nests several alternative models which can be ruled out, including those without dynamics and/or heterogeneity in relative productivity across sectors. We also evaluate alternative interpretations for the dynamic sorting we observe in the data such as saving out of financial constraints and skill accumulation or learning by doing. / Thesis (PhD) — Boston College, 2022. / Submitted to: Boston College.

Serial murder investigations are normally hard for police to handle because of problems that appear internal and external to the police department. While the traditional techniques of investigating a crime (presence witness or witnesses, collecting evidence, and obtaining a confession from the suspect) are helpful in normal situations, their rare application to serial murder cases is only further complicated by other issues. This recognition of investigative issues is critical for not only apprehending these dangerous types of individuals but also for preventing more murders. Case studies of six serial killers have been examined to clarify the issues, using the traditional techniques of investigation as a reference. The data have been interpreted in terms of the factors present in helping to apprehend the offender as well as the problems that hindered the investigation. A final discussion of solutions and the identification of other problems that have not been previously addressed in other works are offered. It is imperative to take note of these issues and work to diminish and/or resolve them for more effectively pursuing serial killers. With acknowledgement of where law enforcement is deficient, a larger effort can be made to not only minimize but possibly even eliminate the errors within an investigation.

This thesis is an assessment of the position of Islamic law and English law regarding the doctrine of the frustration of the contract. The thesis gave in the first general view about Islamic law and Saudi legal system, also about the contract in Islamic law in general. This study provides a detailed and critical account of the principles of frustration of contract law which operate under Islamic law and English law, where appropriate, identifies and critically evaluates the differences between the principles of frustration of contract which operate respectively under Islamic law and English law and to recognize the effect of the frustration on the performance of the contract. In the case of the absence of theory of frustration of contract in Islamic Law, an attempt will be made to create a complete doctrine of frustration of contract. Researcher discussed the frustration of contract in Islamic Law. In the case of the absence of theory of frustration of contract in Islamic Law, an attempt will be made to create a complete theory of frustration of contract in Islamic law. This is recognised owing to the fact that most cases of the application of frustration fall under the doctrine of impossibility. Impossibility can be regarded as taking place ‘when there supervening events without default of either party and for which the contract makes no sufficient provision which so significant changes the nature, if the cases where impossibility relates to the subject-matter of contracts or relates to the parties, subjective or objective impossibility. This study discusses the issue of Frustration of contract due to external factors covering cases of legal impossibility. This study examines the discharge of contract if there is circumstances do not make the performance impossibility but became difficult to perform such as impracticability and frustration of purpose. It will also look in some detail at the limitations and narrow scope of the doctrine of frustration, and also discuss contractual parties’ sometimes preferred alternatives, such as drafting force majeure clauses and hardship clauses.
