Description
The digital forensics community has neglected email forensics as a process, despite the fact that email remains an important tool in the commission of crime. Current forensic practices focus mostly on that of disk forensics, while email forensics is left as an analysis task stemming from that practice. As there is no well-defined process to be used for email forensics the comprehensiveness, extensibility of tools, uniformity of evidence, usefulness in collaborative/distributed environments, and consistency of investigations are hindered. At present, there exists little support for discovering, acquiring, and representing web-based email, despite its widespread use. To remedy this, a systematic process which includes discovering, acquiring, and representing web-based email for email forensics which is integrated into the normal forensic analysis workflow, and which accommodates the distinct characteristics of email evidence will be presented. This process focuses on detecting the presence of non-obvious artifacts related to email accounts, retrieving the data from the service provider, and representing email in a well-structured format based on existing standards. As a result, developers and organizations can collaboratively create and use analysis tools that can analyze email evidence from any source in the same fashion and the examiner can access additional data relevant to their forensic cases. Following, an extensible framework implementing this novel process-driven approach has been implemented in an attempt to address the problems of comprehensiveness, extensibility, uniformity, collaboration/distribution, and consistency within forensic investigations involving email evidence.

Description
With an increasing global interest in Chinese economics and society, more and more native English speakers have started to learn Chinese as a second language (L2). While English and Chinese share a similar word order at the syntactic level, they differ significantly in ways to keep track of reference at the discourse level. There are generally three ways to keep track of reference: repeating the full noun phrase (NP), replacing the full NP with a lexical pronoun, or omitting the NP using zero anaphora. Chinese, a topic-prominent language, allows a wide use of zero anaphora to maintain reference; whereas English, a subject-prominent language, allows only a limited use of zero anaphora. Due to this difference, Chinese as a second language learners whose native language is English (CSL learners), must learn to implement the use of zero anaphora more frequently in their Chinese discourse. The purpose of this study is to investigate how CSL learners keep track of reference using zero anaphora. It is hypothesized that CSL learners at intermediate proficiency level would display a transfer effect from English to Chinese in their Chinese discourse. Specifically, they would produce fewer zero anaphora than native Chinese speakers, and they would also tend to consider discourse with many uses of zero anaphora for reference tracking as less appropriate. To test the hypothesis, a story-retelling task and multiple-choice questions task were adopted. The results of both tasks supported the hypothesis. Meanwhile, it is also evident that the CSL learners have acquired some usage of zero anaphora in their Chinese discourse as the usage of zero anaphora was more frequent when speaking Chinese than English.

Description
This thesis seeks to explore the contrast between the performance of mergers and acquisitions and the propensity of CEOs to enter into these deals. M&A are common means by which firms achieve inorganic growth, but they often perform poorly and fail to accrue expected returns. This apparent contrast between deal popularity and performance prompts further examination and an application of theoretical concepts from the field of strategic management. Following a review of M&A theory, this thesis explores agency theory and managerial hubris and applies these concepts to executive decision-making in M&A. Four hypotheses are presented, evaluating the effects of compensation structure and overconfidence on the M&A decision-making behavior of executives.

This thesis provides a detailed analysis and risk assessment of the various stakeholders impacted by the US Airways-American Airlines merger. The stakeholders include employees, shareholders, new American passengers, the cities of Phoenix and Dallas, and other airlines. In order to understand how these stakeholders are impacted, we did thorough analysis of past major airline mergers and referenced cases from those mergers. Because the history of the airline industry is filled with hundreds of mergers and acquisitions, we only reference the America West-US Airways, Delta-Northwest, United-Continental, and Southwest-AirTran mergers in our thesis.

Abstract Mergers and Acquisitions: A Study of mergers and Acquisitions of Banking Institutions in Arizona and the Effect on the Community Benjamin Paul Taylor II A great deal of research has been conducted on mergers and acquisitions of banks across the country; however, few studies have consisted of mergers of Arizona banks. Therefore, this study focused on (1) gaining a greater insight on how mergers of banks personally enhance or impede employees and the community of Arizona, (2) addressed the issue of whether some bank employees received and "golden parachutes," which are compensation packages given to top level management when banks merge, and (3) provided an "insighter's point of view" by investigating through qualitative methods bank employees' feelings about Arizona bank mergers and acquisitions.

Description
We chose to analyze Apple's current cash and cash equivalents balance of $246.1 billion. To fully understand how to maximize Apple's investment using this cash balance, we performed detailed due diligence on the company. We analyzed the history of apple, a timeline of their major product releases, their financial statements, product mix, and the industries in which they operate. This allowed us to gain a deeper understanding of available opportunities. After doing our due diligence on the company, we look at their current cash levels and potential reasons that the cash balance has been increasing so quickly. Another component of their cash balance is the implications of a tax holiday for repatriation, so we also looked at the potential effects of this on Apple's cash balance. Finally, we begin the main portion of our project where look at the six potential options for the cash. We cover share buybacks, dividends or a special dividend, paying down debt, investing in research and development, making a large acquisition, or continuing to build a high cash balance. We pull data on each of these, look at financial metrics and many different numbers to evaluate which of these six options would maximize shareholder value. A large portion of our work was spent looking at acquisition targets. We finally vetted three potential targets: Tesla, Netflix, and Disney. These companies made sense for a number of different qualitative reasons, but after looking at them from a financial standpoint we concluded Disney was the only company worth modeling out. A detailed financial model was built on Disney to find a purchase price. Included in this was a discounted cash flow analysis, comparable company's analysis, analyzing precedent transactions, and then finding an enterprise value based on the model. We also built an accretion dilution model to see what the effect on earnings per share is and also what the combined entity would look like. In order to present our findings, we built a pitch book. A pitch book is the standard type of presentation that investment banks use in order to show their recommendations to companies.

Description
The purpose of this longitudinal study was to predict /r/ acquisition using acoustic signal processing. 19 children, aged 5-7 with inaccurate /r/, were followed until they turned 8 or acquired /r/, whichever came first. Acoustic and descriptive data from 14 participants were analyzed. The remaining 5 children continued to be followed. The study analyzed differences in spectral energy at the baseline acoustic signals of participants who eventually acquired /r/ compared to that of those who did not acquire /r/. Results indicated significant differences between groups in the baseline signals for vocalic and postvocalic /r/, suggesting that the acquisition of certain allophones may be predictable. Participants’ articulatory changes made during the progression of acquisition were also analyzed spectrally. A retrospective analysis described the pattern in which /r/ allophones were acquired, proposing that vocalic /r/ and the postvocalic variant of consonantal /r/ may be acquired prior to prevocalic /r/, and /r/ followed by low vowels may be acquired before /r/ followed by high vowels, although individual variations exist.

Description
Identifying the hindrances to performing effective talent acquisition within the science, technology, engineering, and mathematics field is an important topic for technical hiring managers. Top candidates have multiple options during highly competitive market conditions requiring managers to look for unique solutions which diverge from competition. Prior to this study there has been very little research considering national laboratory research and development challenges from a technical hiring manager’s talent acquisition perspective. Utilizing a unique combination of national laboratory multi-organization survey, pilot study, Human Resource (HR) tracking data and trust based business strategy to enhance partnering this research finds hiring managers can leverage out of the box techniques to improve internal processes while developing industry support to target highly qualified individuals. This methodology could be utilized by technical hiring managers across federal national laboratory enterprise to effectively capture next generation staff and leadership talent who align with their organization professionally as well as social culture.
