Housing and Confinement of Farm Animals Collection

The purpose was to determine the effects of the physical dimensions of the pen and group size and stocking density on cow activity. Cows (randomly assigned to 4 groups of 6 animals each) were tested in pens with 24 or 12 lying places and in groups with 12 or 6 cows. All groups were tested in each of the 4 treatments with treatment order allocated using a 4 × 4 Latin square. The distance moved and the number of movements were calculated using 5-min scan sampling of video recordings over a 48-h period. Time spent lying down, number of lying …

Mobile Marketing At Telenor: A Mad Strategy?, Yasmin Malik

International Conference on Marketing

In early 2010, Telenor Pakistan became the first local mobile network operator to implement a comprehensive mobile marketing strategy in a market where the true potential for mobile marketing was still nascent and misunderstood by both consumers and brands alike. This case study is the first documented study on how Operator-driven mobile marketing via opt-in based consumer profiling can enable and drive the development of a mobile marketing eco-system in Pakistan - in addition the case study also examines the positioning of the Operator in the mobile marketing value chain.

On Shelf Availability: A Literature Review & Conceptual Framework, Kristie Spielmaker

Marketing Undergraduate Honors Theses

On-Shelf Availability (OSA) is a key performance indicator for the retail industry, greatly impacting profit and customer loyalty. Strong competition in the industry causes retailers and suppliers to put heavy emphasis on improving performance in an effort to satisfy consumers and keep them coming back to their store or product. Over 40 years of research has been done on OSA and its complement, out-of stock (OOS), however very little progress has been made in improving performance in these areas, leading to the belief that gaps in extant research exist. In order to solve the OOS problem, the key drivers of …

The Physical Distribution Security System: Who Is Affecting The Vulnerability Of Goods Transprtation?, Luca Urciuoli

Journal of Transportation Management

The purpose of this study is to explore the vulnerability of physical distribution networks to antago- nistic threats. Previous research identifies globalization and Just in Time (JIT) as the main causes of vulnerability. However, cargo crime has always existed, even before the identification of these trends. In this explorative study new factors are brought to light. In particular, it appears that stake- holders’ dynamics are influencing the level of security.

Food Safety Risks Associated With U.S. Horse Slaughter

Agribusiness Reports

Meat originating from U.S. horses may contain residues from substances banned by the U.S. Food and Drug Administration and the European Union for use in animals intended for consumption. Phenylbutazone, for example, is commonly administered to U.S. horses and has been associated with life-threatening reactions in humans. Requiring a thorough drug history for each U.S. horse intended for human consumption may help circumvent human health risks.

A Comparison Of Logistics Strategies And Integration In The U.S. And Ghana, Michael A. Mcginnis, John E. Spillan, Ali Kara, King Obed Domfeh (Dok)

Journal of Transportation Management

This manuscript empirically compares logistics strategies and outcomes in Ghanaian and U.S. firms to test the underlying factor structure and measurement equivalences of the Bowersox/Daugherty model and its relationship with critical success factors. A structured questionnaire was used to gather data from Ghanaian and American logistics managers. Using confirmatory factor analysis (CFA), we compared the three dimensions of Overall Logistics Strategy (OLS) - Process Strategy, Market Strategy, and Information Strategy – in the two countries. A structural equation model (SEM) was then used to assess the impact of OLS on perceived organizational competitiveness in the two countries. Although the economic, …

Assessing The Strategic Evolution Of U.S. Low Cost Airlines In The Post-9/11 Environment, Carl A. Scheraga, Paul Caster

Journal of Transportation Management

It has been suggested in the literature that low-cost airlines have, in varying degrees, departed from the original low-cost model introduced by Southwest Airlines. This study provides a multi-year analysis in the post-9/11 time period, for the years 2004-2009, of the demonstrated strategic positioning choices of U. S. low-cost airlines. The sample utilized is restricted to U. S. low-cost carriers so as not to conflate operating environments. Furthermore, a quantitative methodology is employed to measure effectively these choices and to facilitate inter-airline comparisons. Airlines, as part of their strategic planning process, articulate positions with regard to cost leadership, product differentiation, …

Understanding Supply Chain Security Strategy, Zachary Williams, Jason E. Lueg, Sean P. Goffnett, Stephen A. Lemay, Robert L. Cook

Journal of Transportation Management

In the post-9/11 environment, organizations are acutely aware of the need to secure their supply chains from risks of being a target of, or an unwilling participant in, a terror attack. However, supply chain security (SCS) comes at a cost and increasing levels of protection have increasing levels of costs to the firm. So some firms engage in strategic initiatives to secure the supply chain (SC) while others do not; and each firm engages in varying degrees of activities to ensure SCS. Therefore, in this study, the researchers sought to explore what types of SCS strategies exist. The researchers analyze …

The Role Of Returns Management Orientation, Internal Collaboration, And Information Support In Reverse Logistics, Enping (Shirley) Mai, Haozhe Chen, Kenneth Anselmi

Journal of Transportation Management

While reverse logistics has gained significant interest in recent years, the research on its antecedents is still far from comprehensive. The current study utilizes data collected from China to empirically test a conceptual model that is developed based on the resource based view of the firm. It is proposed that returns management orientation, internal collaboration, and information support are important predictors of reverse logistics performance. The structural equation modeling analysis supports these proposed relationships. Furthermore, the current study also confirms the positive relationship between a firm’s reverse logistics performance and market performance.

Evaluation Of Different Electronic Product Code Discovery Service Models, Su Mon Kywe, Jie Shi, Yingjiu Li, Raghuwanshi Kailash

Research Collection School Of Computing and Information Systems

Electronic Product Code Discovery Service (EPCDS) is an important concept in supply chain processes and in Internet of Things (IOT). It allows supply chain participants to search for their partners, communicate with them and share product information using standardized interfaces securely. Many researchers have been proposing different EPCDS models, considering different requirements. In this paper, we describe existing architecture designs of EPCDS systems, namely Directory Service Model, Query Relay Model and Aggregating Discovery Service Model (ADS). We also briefly mention Secure Discovery Service (SecDS) Model, which is an improved version of Directory Service Model with a secure attribute-based access control …

Cng As A Feasible Replacement For The U.S. Transportation Sector, Veysel Uz

Theses and Dissertations

For many years there has been much attention on reducing U.S. fuel imports to improve the nation's energy independence. Much of the focus has been on the transportation sector, as it accounts for 28% of total U.S. energy consumption. This thesis examines compressed natural gas (CNG) as a possible alternative fuel for the U.S. transportation sector. To fully explore this possibility, it is essential to understand both the supply and demand sides of the problem. This research examines the availability and adequacy of CNG as a full or partial fuel replacement for U.S. transportation fuels, the factors that prevent CNG …

A Spreadsheet Model That Estimates The Impact Of Reduced Distribution Time On Inventory Investment Savings: What Is A Day Taken Out Of The Pipeline Worth In Inventory?, Serhat Saylam

Theses and Dissertations

In most of the literature dealing with inventory problems, either with a deterministic or probabilistic model, lead time is viewed as a prescribed constant or a stochastic variable that is not subject to control. But in many practical situations, lead time can be reduced by an extra crashing cost; in other words, it is controllable. This study proposes a repeatable spreadsheet optimization model that estimates the impact of reduced replenishment lead time on inventory investment savings at forward and strategic locations to motivate decision makers to support enterprise-wide distribution process improvement. The study provides users with a means of automatically …

An Assessment Tool Of Performance Based Logistics Appropriateness, Korhan G. Yukselen

Theses and Dissertations

Performance-Based Logistics (PBL) is the most preferred product support strategy in the Department of Defense. Using performance-based acquisition methods to the maximum extent practicable when acquiring services is mandated. But although PBL should be used whenever feasible, few documents show how to measure its feasibility. The aim of this research is to fill this gap by answering the following question: What factors determine the appropriateness of the selection of PBL as a strategy for a specific acquisition? This study seeks to determine which factors affect success when selecting PBL as an acquisition method. Each factor is examined in detail and …

Examining Express With Simulation, David R. Williams

Theses and Dissertations

The Execution and Prioritization of Repair Support System (EXPRESS) is a database tool used by the Air Force to prioritize depot maintenance of reparable spare parts to maximize responsiveness to warfighter need. Many studies have examined individual portions of EXPRESS, though few have examined it as an entire system. This effort proposes a modeling approach for examining the overall system behavior of EXPRESS using discrete event simulation. The emphasis of the model is to be flexible enough to provide useful insight into system performance, while also remaining open-ended enough to provide a foundation for future expansion and analysis. A case …

The Impact Of Supply Chain Business Processes On Competitive Advantage And Organizational Performance, John F. Perry Ii

Theses and Dissertations

Organizational performance has routinely been viewed through a limited scope primarily focused on functions, practices, and resources directly controlled by the focal organization, but supply chain management (SCM) has broadened this scope to incorporate all organizations along the supply chain. This shifted the notion of competition from that of between individual organizations to between supply chains. Supply chain management is an ever growing field; multiple SCM frameworks exist today and are being further developed and defined. Successful firms must reside on the leading edge of management techniques, theories, and practices in order to stay competitive in an ever growing, more …

The Relationship Between Key Supply Chain Process Implementation, Competitive Advantage, & Organizational Performance, Anthonelli White Jr.

Theses and Dissertations

In spite of an ever-accumulating body of research on the topic of supply chain management (SCM), an agreed upon definition or framework regarding its essential constructs or practices does not exist. There are, however, a few leading academic perspectives on SCM that have been bolstered by the acceptance of industry leaders. One such perspective is that presented by the Global Supply Chain Forum (GSCF). This study applies established survey methods to expand the body of knowledge pertaining to SCM by empirically validating the relationships conceptualized by the GSCF framework through an analysis of the perception of mid-level managers and senior-level …

Evaluation Of Inventory Reduction Strategies: Balad Air Base Case Study, Aaron V. Glassburner

Theses and Dissertations

The end of military operations in Iraq brought a new set of challenges for Air Force supply professionals as they responsibly reduced levels of assets within the country while supporting on-going missions. This research evaluates two separate supply reduction plans that were implemented at Balad Air Base during the Air Force's final months in the area of operations. The logic of Air Force consumable inventory computations are modeled in detail and historical data from supply records are utilized to evaluate each plan's supportability to different notional fleet sizes. Each plan is evaluated under measures of backorders, backorder quantities, and customer …
