Expatriate Workers And Its Repercussions On The Economy And Labor Market In Iraq After 2003, Yusur Qasim Dawood, Lawrence Yahiya Saleh Al- Kubaisi

Journal of Economics and Administrative Sciences

The demand for expatriate labor to Iraq increased after 2003 as a result of the openness that Iraq experienced, but this expatriate labor, which was requested at an increasing rate, has had economic, social, and political effects on the Iraqi economy in general, and the Iraqi labor market in particular. This is due to the high rates of unemployment, as most of these expatriate workers cause competition to local labor, and thus cause repercussions on the Iraqi economy as a whole, except for those expatriate workers coming with companies working in the oil sector. Iraq's GDP

The Effectiveness Of Indicators Of Financial Discipline In Strengthening The Exchange Rate, With A Special Reference To Iraq, Karrar Mahdi Fenjan, Mohammed Saleh Salman Al-Kubaisi

Journal of Economics and Administrative Sciences

Controlling public expenditures is one of the main objectives of the public budget. The public budget often suffers from a deficit, whether in developed or developing countries, because expenditures are usually greater than the revenues generated. This requires the existence of financial rules that are adhered to by the government, which in turn leads to discipline. Fiscal policy leads to a reduction in the obligations incumbent on the government. Adhering to the financial rules would correct the course of fiscal policy in Iraq, with the need to direct oil revenues in the years of financial abundance when global oil prices …

Sigesn Light-Emitting Devices: From Optical To Electrical Injection, Yiyin Zhou

Graduate Theses and Dissertations

Si photonics is a fast-developing technology that impacts many applications such as data centers, 5G, Lidar, and biological/chemical sensing. One of the merits of Si photonics is to integrate electronic and photonic components on a single chip to form a complex functional system that features compact, low-cost, high-performance, and reliability. Among all building blocks, the monolithic integration of lasers on Si encountered substantial challenges. Si and Ge, conventional epitaxial material on Si, are incompetent for light emission due to the indirect bandgap. The current solution compromises the hybrid integration of III-V lasers, which requires growing on separate smaller size substrates …

Sleeping With The Enemy: Examining The Relationship Between Sleep And Pain In Post-9/11 Veterans, John L. Schwartz Jr.

Psychology Theses & Dissertations

United States veterans are a diverse group of individuals, yet as a result of their service, they share a unique set of customs, traditions, and values. Post-9/11 veterans are more likely to experience elevated levels of pain and poor sleep quality compared to their civilian counterparts; however, little is known about how beliefs related to veterans’ pain impact their sleep and how levels of pain acceptance influence the sleep-pain association. This study examined relationships between sleep and pain in a sample of 102 post-9/11 veterans. Results support associations between pain and sleep identified in other populations. Positive correlations were found …

Closing The Contextual And Chronological Gap: A Design And Development Study Of A Systematic Tool For The Selection Of Learning And Performance Support Interventions, James Knapp Iii

STEMPS Theses & Dissertations

Gaps in human performance resulting from a lack of skills and knowledge require solutions – interventions. The process of selecting the most effective intervention (solution) for closing a skills and knowledge gap—such as classroom training, e-Learning, Structured on-the-job Training (SOJT), or job-aid—is a fundamental and vital practice for Human Performance Technology (HPT) practitioners. Unlike other activities in the Performance Improvement/HPT (PI/HPT) model, the activity of intervention selection is ambiguous. Meaning, there is currently no systematic process or tool in place for selecting learning and performance-improvement solutions that is reflective of the learning science. Consequently, the critical activity of intervention selection …

An Experimental Investigation Into The Impact Of Acute Stress On Alcohol Craving Through Implicit Coping Motives, Douglas J. Glenn

Psychology Theses & Dissertations

Drinking to cope with negative emotions is associated with many negative alcohol-related outcomes such as increased alcohol use, drinking-related problems, and alcohol use disorders. An acute stressor is one example of a stimulus leading to negative emotions that an individual may wish to avoid. Research has shown that acute stress positively relates to drinking. Specifically, previous experimental studies have shown that individuals exposed to a stressor drink more alcohol and have stronger urges to drink than those not exposed to a stressor. Thus, it may be that drinking to cope explains why people experience alcohol cravings after experiencing a stressor. …

How Leader And Follower Mindfulness Relate To Performance And Ocb Through Conversation Quality And Empathy: A Moderated Mediation Model, Arianna White-Levatich

Psychology Theses & Dissertations

Interest within the organizational research community regarding mindfulness has recently surged. Little research, however, has examined how employees’ mindfulness may influence interactions between leaders and followers. This study examined how followers’ trait mindfulness related to two specific aspects of dyadic interactions: leader – member conversational quality (LMCQ) and follower empathy toward a leader. Further, the study examined how this influence extended (via LMCQ and leader-oriented empathy) to task performance and organizational citizenship behavior (OCB), two important workplace outcomes for followers. Leader mindfulness was also expected to have a significant influence on the relationships, in that it was expected to strengthen …

Emotion Regulation Variability And Relationship Functioning In Emerging Adulthood, Laura B. Kenneally

Psychology Theses & Dissertations

Emotion regulation is a transdiagnostic factor that functions as a crucial contributor to individual well-being and social functioning. Research seeking to identify adaptive or maladaptive strategies of emotion regulation has often focused on individual strategies, though emerging evidence suggests that what constitutes “adaptive” regulation is often context-dependent. Having a large repertoire of emotion regulation strategies that one is willing to use at different rates has been termed “emotion regulation variability,” and has been linked to positive individual outcomes. While the benefits of emotion regulation variability have been demonstrated on an individual level, the impact on romantic relationships has yet to …

Language And Cultural Identity In Post-Soviet Frozen Conflicts, Irina Paquette

Graduate Program in International Studies Theses & Dissertations

How we, as humans, define ourselves and our national and ethnic distinction often centers on visible characteristics—physical features, group traditions, and language. Of those, language is both mutable and plays such a central role in daily life that it is often a hotly contested and manipulated factor in defining national identity. This paper examines the role language has played in the formation of crisis situations in the former Soviet Union. Linguistic identity has been used as a basis to establish the legitimacy of independence for both Soviet republics and separatist groups within those republics. As such, it is a highly …

The Impact Of A Crisis Intervention Team Program On Psychiatric Boarding, Kurtis Hooks

Counseling & Human Services Theses & Dissertations

Psychiatric boarding is the phenomenon of housing individuals in emergency departments while awaiting access to mental health services in the community. The expansion of psychiatric boarding is attributed to continued deinstitutionalization and under-resourcing of mental health services. Psychiatric boarding is also associated with deleterious outcomes for individuals in need of access to behavioral health services, facilities. There is limited research on programmatic efforts to reduce psychiatric boarding as it pertains to Crisis Intervention Team programs colocated in medical settings.

Experiences Of Low-Income Student-Parents At A Community College During The Coronavirus (Covid-19) Pandemic, Marlena Yvonne Jarboe

Educational Leadership & Workforce Development Theses & Dissertations

Twenty-two percent of United States undergraduate students are parents (Cruse, et al., 2020). Referred to as student-parents, they are most likely to have low-incomes and attend community colleges (Cruse, et al., 2019; Gault et al., 2014). They tend to reduce their course loads and drop out of college due to work-life balance challenges even though they typically have better grade point averages than their non-parent peers (Cruse et al., 2019; Manze, et al., 2021; Peterson, 2016).

The problem to be addressed was how community college instructors, leaders, and legislators can support low-income student-parents’ persistence toward a postsecondary credential. There is …

The Second-Order Impact Of Relative Power On Outcomes Of Crisis Bargaining: A Theory Of Expected Disutility And Resolve, Tatevik Movsisyan

Graduate Program in International Studies Theses & Dissertations

How does structure shape behavior and outcomes in crisis bargaining? Formal bargaining models of war rely on expected utility theory to describe first-order effects, whereby the payoffs of war determine actors’ “resolve” to fight as a function of costs and benefits. Value preferences of risk and future discounting are routinely treated as predefined and subjective individual attributes, outside the strategic context of bargaining or independent from expected utility. However, such treatment fails to account for context-conditional preferences sourcing from actors’ expectations of relative gain or loss. Drawing on a wealth of experimental evidence from behavioral economics, but without departing from …

Hydrothermal Processes For Extraction And Conversion Of Biomass To Produce Biofuels And Value-Added Products, Anuj Hemant Thakkar

Civil & Environmental Engineering Theses & Dissertations

An integrated biorefinery approach based on subcritical hydrothermal processes was developed to maximize utilization of biomass components by producing multiple products. Biomass from various sources like agricultural waste (lignocellulose), food waste (spent yeast), and dedicated cultivation (micro-algae) was used in this research.

Corn stover (agricultural waste) was hydrothermally pretreated to remove lignin and xylan while preserving most of the glucan. The pretreated corn stover was utilized to produce levulinic acid (thermochemically) and fermentable sugars (biochemically). The solid residue generated during levulinic acid production was utilized to produce biocarbon electrode material. The results generated from the experiments were used for designing …

Shipboard Lidar As A Tool For Remotely Measuring The Distribution And Bulk Characteristics Of Marine Particles, Brian Leigh Collister

OES Theses and Dissertations

Light detection and ranging (lidar) can provide remote estimates of the vertical distribution of optical properties in the ocean, potentially revolutionizing our ability to characterize the spatial structure of upper ocean ecosystems. However, challenges associated with quantifying the relationship between lidar measurements and biogeochemical properties of interest have prevented its adoption for routinely mapping the vertical structure of marine ecosystems. To address this, we developed a shipboard oceanographic lidar that measures attenuation (α) and linear depolarization (δ) at scales identical to those of in-water optical and biogeochemical measurements. The instrument’s ability to resolve the distribution of optical and biogeochemical properties …

A Testing And Experimenting Environment For Microscopic Traffic Simulation Utilizing Virtual Reality And Augmented Reality, Mahmud Hasan

Computational Modeling & Simulation Engineering Theses & Dissertations

Microscopic traffic simulation (MTS) is the emulation of real-world traffic movements in a virtual environment with various traffic entities. Typically, the movements of the vehicles in MTS follow some predefined algorithms, e.g., car-following models, lane changing models, etc. Moreover, existing MTS models only provide a limited capability of two- and/or three-dimensional displays that often restrict the user’s viewpoint to a flat screen. Their downscaled scenes neither provide a realistic representation of the environment nor allow different users to simultaneously experience or interact with the simulation model from different perspectives. These limitations neither allow the traffic engineers to effectively disseminate their …

Mobilizing Discomfort For Water Security As A Human Right: A Newspaper Analysis Of Social Conflict In South Africa, Madison Gonzalez

Graduate Program in International Studies Theses & Dissertations

There are 884 million people globally that do not have access to improved drinking water, while 2.5 billion do not have improved access to sanitation (Office of the High Commissioner for Human Rights, 2010). Those living in informal settlements and slums—what I call the ‘solidaric disaffiliated’ zones—represent one such location where individuals around the world have found themselves in a situation of neglected crisis as their geographic, economic, and social expulsion pushes them beyond the reach of opportunity and access to basic human rights such as water and sanitation. As individuals feel their dignity deteriorating due to the extreme precarity …

Norm Contestation And Its Effects On Emergence Of A New Norm, Khadijeh Salimi

Graduate Program in International Studies Theses & Dissertations

The objective of this study is to propose a theoretical model to investigate the mechanism by which contesting of a harmful legal norm by powerless individual actors results in the emergence of a new norm. While much work has been done on norm contestation at the “actor level” in the field, the structural conditions under which contesting of harmful norms by powerless individual actors lead to emergence of a new norm have been insufficiently studied, especially in the non-democratic cultural context. I developed a model that combine existing causal theories in one frame to reproduce observe conditions in the real …

Data-Driven Operational And Safety Analysis Of Emerging Shared Electric Scooter Systems, Qingyu Ma

Computational Modeling & Simulation Engineering Theses & Dissertations

The rapid rise of shared electric scooter (E-Scooter) systems offers many urban areas a new micro-mobility solution. The portable and flexible characteristics have made E-Scooters a competitive mode for short-distance trips. Compared to other modes such as bikes, E-Scooters allow riders to freely ride on different facilities such as streets, sidewalks, and bike lanes. However, sharing lanes with vehicles and other users tends to cause safety issues for riding E-Scooters. Conventional methods are often not applicable for analyzing such safety issues because well-archived historical crash records are not commonly available for emerging E-Scooters.

Perceiving the growth of such a micro-mobility …

Elementary Classroom Teachers’ Perceptions Of Redesigned Classroom Space: A Qualitative Case Study, Kristin Lee Pender

Teaching & Learning Theses & Dissertations

Classroom redesign is being recognized globally as necessary to better increase student’s enjoyment levels, engagement, collaboration, and learning. Instead of seeing traditional classrooms in a fixed setting where students are seated in rows facing the front of the room, classrooms are being arranged in multiple ways. As a result of this focus on redesigned learning spaces, there is a need to examine teachers’ perceptions about redesigned classroom spaces and understand the decisions behind their design. Thus, it is important to examine teachers’ perceptions of their classroom space to better understand if they consider their students learning needs, engagement levels, and …
