إدارة المصارف الإسلامية ودورها في تحقيق التنمية الاقتصادية بعض المصارف الإسلامية العربية إنموذجاً للمدة 2006- 2013, صباح رحيم مهدي الاسدي

Muthanna Journal of Administrative and Economics Sciences

ان الغاية من انشاء المصارف الاسلامية، هي مواجهة التحديات التي تواجه المسلمون من خلال تعاملاتهم المالية والاستثمارية، وما لها من علاقة بالمصارف التجارية، لان اغلب المعاملات التجارية تحتاج الى ايداع وسحب وأتمان مصرفي، وخوفا من الوقوع بدائرة الحرام من خلال التعاملات الربوية (التعامل بالفائدة). فجاءت فكرة انشاء المصارف الاسلامية ترسيخا لمبادئ التعاليم الاسلامية وادراكا لحجم التحديات التي تعاني منها الامة الاسلامية في مجالها الاقتصادي، لذا كان من الضروري ايجاد آلية فاعلة للتصدي لتلك التحديات، من خلال تكوين مؤسسات مصرفية تنموية هدفها الابتعاد عن التعامل بالفائدة، وفي الوقت نفسه العمل على دعم التنمية الاقتصادية والتقدم الاجتماعي للشعوب والمجتمعات الاسلامية وفقا لمبادئ …

Shop Around: An Experiment On Air Force Vehicle Parts Procurement, Melvin K. Boothe

Theses and Dissertations

Current procurement processes for vehicle parts vary substantially across the Air Force. Many of these parts are "commercial off-the-shelf" items that are procured through local vendors via a government purchase card. Understanding what guidance dictates various purchasing processes and how that guidance affects the behavior of purchasers is unknown. A mixed method approach of semi-structured interviews of purchasers at multiple bases and an experimental survey testing different sets of guidance are used to understand the effects of guidance, as well as produce recommendations for action and future research for leaders at the local and headquarters levels.

Not All Tons Are Created Equal; Analyzing Aerial Port Capability To Define The Working Ton, Casey L. Owens

Theses and Dissertations

United States Transportation Command (TRANSCOM) along with Air Mobility Command (AMC) provide airlift assets that accomplish thousands of missions around the world every week for cargo distribution. The current unit of measure is a short ton, which is the primary metric used in decision making. However, the short ton measurement does not adequately predict the amount of work necessary to properly prepare different cargo types for airlift. Utilizing the short ton metric leads to inadequate forecasting times for cargo preparation and aircraft loading, which leads to delayed missions. The root of the problem is that the metric used does not …

Managing Supply Discrepancies: The Effect Of Performance Measurement And Feedback On Order Fulfillment Quality, Michael J. Weber

Theses and Dissertations

Extensive research on the impact of shipping and packaging errors in the private sector finds numerous negative outcomes, including reduced customer satisfaction, reduced customer loyalty, and lower profitability. However, little research has been done examining the impact of order fulfillment errors on military operations. The purpose of this research is to quantify the impact of supply discrepancy reports (SDRs) on military aircraft readiness metrics, including cannibalizations, not mission capable supply (NMCS) hours, aircraft availability and MICAP hours. Results show SDRs significantly impact aircraft readiness metrics in seven of the fifteen analyses conducted. Additionally, a quasi-experimental study is implemented at DLA …

Flightline Heroics And The Façade Of A Healthy Common Support Equipment Fleet, Benjamin D. Bobic

Theses and Dissertations

Access to serviceable support equipment enables aircraft maintenance crews the ability to efficiently keep assigned aircraft safe and mission capable. Current Air Force policy does not require formal management and enterprise fleet health reporting of serialized support equipment. As such, articulating funding requirements to replace equipment has been a challenge for equipment managers. To better articulate support equipment requirements, equipment managers need quantifiable support equipment data. A previous study examined the relationship between aircraft availability and support equipment availability. While finding no significant correlation, the author identifies the practices of "Frankensteining" and "Beg-Borrow-Steal" as possible reasons for the absence of …

C-130j Inventory Control Point Location Determination, Joshua P. Casey

Theses and Dissertations

Since the first C-130J delivery in 1999, Lockheed Martin has managed the USAF’s C-130J “peculiar” parts inventory at Keesler AFB. Now with 193 aircraft assigned to 17 operating locations across the globe, effective supply chain management and recognized cost savings are essential components to mission success and fleet longevity. Previous research within the area of location analysis has shown that minimizing the average weighted distance of shipping products can assist in cost reduction efforts. Due to this, the goal of this study is to determine if alternative CONUS C-130J locations can be utilized as the Inventory Control Point to help …

Resilient Aircraft Maintenance Constructs: Enhancing Repair Network Designs To Effectively Manage Risks And Supply Chain Interruptions, Thomas S. Bihansky

Theses and Dissertations

This research aims to extend the understanding of supply chain resiliency by utilizing a simulation model of a U.S. Air Force aircraft engine repair network to evaluate the degree of resiliency built into the system. The study compares the recovery time of the disrupted current system to that of a fully-integrated repair network; the objective being the quantification of resiliency in the current networks design and gauging the effectiveness of various strategies in reducing recovery time. This contributes to current literature by bridging the explicit gap on how to quantify, measure, and compare resilient supply chain strategies and also provides …

Critical Issues In The Air Force Medical Equipment Procurement Process, Samuel H. Pang

Theses and Dissertations

The Air Force medical logistics community relies on multiple contracting offices to acquire medical equipment for the Air Force Medical Service. The perception is that burdensome regulations contribute to the challenges faced in the procurement process. This research takes a broader examination to understand the factors leading to long lead times and delayed procurements. Process mapping and interviews with the key stakeholders supporting medical equipment procurement determined that the critical issues were a lack of centralized medical equipment contracting authority, insufficient market research and inconsistent local knowledge on contracting processes. This research provides future recommendations for the Air Force Medical …

Efficiency Driver In Nigerian Airports: A Bootstrap Dea–Censored Quantile Regression Approach, Obioma Reuben Nwaogbe, Peter Wanke, Innocent Chukwuka Ogwude, Carlos Pestana Barros, Abul Kalam Azad

Journal of Aviation Technology and Engineering

This paper reports on the use of a novel two-stage approach for assessing the efficiency of 30 major Nigerian airports from 2003 to 2013 based on bootstrapped data envelopment analysis (DEA) and censored quantile regression. In the first stage, bootstrapped efficiency estimates are computed. They enable bias correction and testing for significant differences in efficiency levels among airports. Subsequently, bootstrapped DEA results are combined with censored quantile regression to assess the impact of contextual variables—related to the airports’ ownership, location, and network connectivity—on different efficiency percentiles. The results reveal that the intensity of significant impacts regarding airports’ contextual variables may …

Quadratic Two-Stage Stochastic Optimization With Coherent Measures Of Risk, Jie Sun, Li-Zhi Liao, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

A new scheme to cope with two-stage stochastic optimization problems uses a risk measure as the objective function of the recourse action, where the risk measure is defined as the worst-case expected values over a set of constrained distributions. This paper develops an approach to deal with the case where both the first and second stage objective functions are convex linear-quadratic. It is shown that under a standard set of regularity assumptions, this two-stage quadratic stochastic optimization problem with measures of risk is equivalent to a conic optimization problem that can be solved in polynomial time.

Constrained Dual Representation Of Coherent Risk Measures, Marcus Ang, Jie Sun, Qiang Yao

Research Collection Lee Kong Chian School Of Business

A classical result in risk measure theory states that every coherent risk measure has a dual representation as the supremum of certain expected value over a risk envelope. We study this topic in more detail. The related issues include: (1) Set operations of risk envelopes and how they change the risk measures, (2) The structure of risk envelopes of popular risk measures, (3) Aversity of risk measures and its impact to risk envelopes, and (4) A connection between risk measures in stochastic optimization and uncertainty sets in robust optimization.

The Emerging International Taxation Problems, James G. Yang, Victor N.A. Metallo

Department of Accounting and Finance Faculty Scholarship and Creative Works

The problems of tax evasion and tax avoidance are as old as taxes themselves. Between 2015 and 2016 alone, many U.S. multinational corporations were involved in tax disputes with the European Commission. From a historical perspective, these disputes are unprecedented as they have resulted in tremendous amount of tax penalties. The most notable case was Apple for €13 billion of unpaid tax. This article discusses what tax strategies these corporations used that caused such disputes. It specifically investigates seven corporations: Apple Inc., McDonald’s, Starbucks, Fiat, Amazon, Google, and Ikea, and elaborates on the following tax strategies: high royalties, intercompany transfer …
