Requirement Elicitation, Cameron Myers

Honors Theses

Requirement Elicitation is a flexible and malleable process that can be changed based upon the requirements of the analyst, stakeholders, and/or the application. In recent years analysts have given more distinction to the effectiveness and the types of result yielded based on the unique attributes of each elicitation technique. These distinctions arose because of advancing technology and use cases used when developing an application. Naturally, the elicitation techniques are advancing as well. They are advancing into different categories to better focus on yielding the right information to identify the right requirements. Such as behavioral techniques, cognitive techniques, contrived techniques, etc. …

Refugee Camp Education: Hope, Gaps, And Barriers, Allyson Dykstra

Honors Theses

The urgency to provide humane living conditions such as food, shelter, safety and education grows with the refugee population as temporary stays become more permanent. Refugees are staying longer in emergency arrangements, which appears to affect mental health, ability to hope, and sustainable coping mechanisms for these populations. With dissatisfactory conditions in camps, this paper intends to explore how refugees cope with their environment and in what ways needs are not being met, in order to explain the present condition of refugee health, their coping mechanisms, and how to combat it.

Reshaping The United States' Anti-Trafficking Legislation: The Need For Uniform Reporting And Victim Rehabilitation, Bryant Cross

Honors Theses

Trafficking in persons—or “human trafficking”—is a prevalent issue in the United States in the twenty-first century. Since the turn of the century, awareness surrounding the national and international problem of human trafficking has gradually risen. This rise in awareness came hand-in-hand with Congressional efforts to combat the trafficking of human beings through federal law—namely, the Trafficking Victims Protection Act (TVPA) of 2000 and its subsequent reauthorizations. Unfortunately, federal legislators’ initial framing of the trafficking in persons problem as an international issue—rather than a national issue—led to the creation of a weak legislative foundation for anti-trafficking efforts in the United States. …

The Peaceful Transition Of Spain: How Authoritarianism Became Democracy, Emma Haiser

Honors Theses

The peaceful transition from authoritarianism under Francisco Franco to a democratic constitutional monarchy after Franco’s death stands as a critical juncture in modern Spanish history because of the uniqueness of the historical event. The transition occurred without direct foreign intervention to manipulate Spanish politicians into passing democratic legislation; instead, the transition was initiated by Francoist leaders who willingly enacted the regime’s change which undermined their initial place in society. The Spanish transition was caused by three main factors: societal opposition to the Francoist regime, democratic international influence, and progressive leaders taking office after Franco’s death. This paper will explore the …

Food Insecurity On Wmu’S Campus: Student Satisfaction Of The Invisible Need Project, Ava Daly

The Macroevolution Of Diadromous And Non-Diadromous Clupeiformes., Lindsey Dehaan

Honors Theses

Migration is a common life history strategy across the animal tree of life. This behavior is energetically demanding and may trigger strong selection for the evolution of an optimal ecomorphology to lessen energetic costs, yet the ecomorphology of migratory aquatic species remains poorly understood. Previous studies have demonstrated that migratory fishes exhibit predictable phenotypic patterns in body size evolution in response to evolving migration: migratory fishes are larger than non-migratory fishes. Migratory fishes may also have functional traits (e.g. fin shape) associated with locomotion that have experienced similar selective forces and exhibit predictable evolutionary patterns, resulting in migratory lineages sharing …

How Do Israelis And Palestinians Interpret Their Own Histories As Evidence That They Have Claim Over Israeli Held Territory?, Jacob Kubiak

Honors Theses

The Israeli-Palestinian War over Israeli-held territories has been a major controversy for many years. The modern conflict has been raging on since 1948. This conflict has caused the displacement of 1.4 million Palestinians, uprooting them from what they believe to be their ancestral home. Along with this displacement, the conflict has caused infrastructural collapse and the rise of terrorist organizations within Israel and Palestinian territories. Both groups have their own evidence in claiming the Israeli-held territory, including archaeological history and ancient texts to argue that they are the rightful owners of this land. The narratives of land claim belief are …

The Impact Of Goal Orientation And Learning Organization On Mobbing Of Academic Advisors In The U.S., Bette A. Ludwig

Dissertations

Mobbing emerged in research decades ago as a way to understand aggressive behavior in the animal kingdom (Lorenz, 1966). This same concept has been adapted for higher education to explain acts of incivility and negative behaviors employees experience within their institutions (Duffy & Sperry, 2007, 2012; Harper, 2016; Yelgecen & Kokalan, 2009). The theory of mobbing encompasses both the organization and the aggressor.

This quantitative study, operationalized using measurable behaviors from the Work Domain Goal Orientation Questionnaire (Vandewalle, 1997), the Dimension of Learning Organization Questionnaire (Watkins and Marsick, 1993), and the Negative Acts Questionnaire (Einarsen, 1997), researches mastery orientation, performance …

Simultaneous X-Ray Emission Accompanying Two Electron Capture For Fluorine On Gas Targets, David S. La Mantia

Dissertations

The collision between a charged ion and an atom resulting in the capture of two electrons, simultaneous with the emission of a single photon is referred to as radiative double electron capture (RDEC). For ion-atom collisions, this process can be considered the inverse of double photoionization. The study of either process, where just two electrons are involved without influence from neighboring electrons, promises new insight into electron correlation and the role it plays in quantum mechanics. Such a study for photoionization has not yet been done experimentally for two-electron ions because the only target system for which two electrons are …
