Bong Joon Ho, Okja (2017): Wounding The Feelings, Nagehan Uzuner
Bong Joon Ho, Okja (2017): Wounding The Feelings, Nagehan Uzuner
Markets, Globalization & Development Review
Okja is a cute fictitious pig which is created in the laboratory as a solution for the meat industry to prevent hunger, which is one of the important problems of our contemporary century and the near future of the humanity. This pig-like, depicted as an ecological food source of the industrial society, is commodified for the mediation of the spheres within the society. Okja, as a film, falls within the intersections of food industry, feminism, orientalism, mediatization and globalization concepts. I try to understand and redefine the movie through contradictions such as East-West, women-men, good-evil. The review reexamines multiple interacting …

This paper estimates the potential economic and operational impacts of commercial space horizontal launch activities on airlines under various launch scenarios using predictive fast-time simulation modeling, focusing on Cecil Air and Space Port in Jacksonville (Florida) and the rules governing the national airspace system (NAS) in the United States. Our results indicate that the …
Supply Chain Student Biases Regarding Transportation Jobs, Drew Mahosky
Supply Chain Student Biases Regarding Transportation Jobs, Drew Mahosky
Information Systems Undergraduate Honors Theses
As a Supply Chain student at the University of Arkansas, I have made some observations about how students view jobs with a transportation focus. I have seen other students gravitate towards jobs on the consumer-side of the supply chain job market, with many joining large companies like Walmart and Amazon. The university itself has helped instill this feeling in me as well, due to their focus more on the consumer-side of supply chains. There have only been two classes offered to me thus far in my degree plan that I felt truly addressed transportation-side supply chains at all, with them …

The Obstacles To The Modernization Of Common Support Equipment, J. Erik Ritschard
Theses and Dissertations
The current fleet of Common Support Equipment (CSE) is faced with a $2B funding disconnect that threatens 9 of the 12 USAF Core Functions. This research identifies the barriers to efforts to modernize CSE across the sustainment, acquisition, and maintenance communities. Using a qualitative, grounded theory methodology, the responses are explored of interviewed Support Equipment managers responsible for the sustainment and modernization of CSE. Significant barriers to current modernization efforts were exposed, resulting in expensive, duplicative, and unreliable equipment; concluding that the AF must change the way CSE is administrated, funded, and culturally understood to prevent future mission degradation.

Resupply Operations Of A Dispersed Infantry Brigade Combat Team Using Approximate Dynamic Programming, Camero K. Song
Resupply Operations Of A Dispersed Infantry Brigade Combat Team Using Approximate Dynamic Programming, Camero K. Song
Theses and Dissertations
Military sustainment planners must consider the effective employment of Cargo Unmanned Aerial Vehicles (CUAVs) into resupply operations under austere threat conditions. Viewed as an inventory routing problem, the complexities of resupplying dislocated Forward Operating Bases (FOBs) under dangerous and dynamic conditions warrant additional features to the baseline problem. This research models a military stochastic inventory routing problem with multiple routing (MIL SIRP- MR) as a Markov decision process (MDP) model and provides high-quality policy solutions using a combination of approximate dynamic programming and ordinal optimization techniques.

Learning By Supplying And Competition Threat, Yi-Fan Chen, Alireza Naghavi, Shin-Kun Peng
Learning By Supplying And Competition Threat, Yi-Fan Chen, Alireza Naghavi, Shin-Kun Peng
Research Collection School Of Economics
This study proposes a model of learning by supplying in an international outsourcing framework, where the supplier of a relationship-specific input can reverse engineer and become a competitor to its partner in the final goods market. Transmitting knowledge to a more capable supplier therefore creates competitive threat despite the benefits it brings within an outsourcing relationship. In particular, in markets with less differentiated products and for standard inputs that require less knowledge to be shared, choosing an intermediate capability level supplier prompts a strategic expansion of output to deter supplier entry in the final goods market, resulting in higher profits …

Research Collection School Of Computing and Information Systems
With the deepening of power market reform, distributed power generation is gaining momentum. This paper tests the distributed photovoltaic (DPV) economy under different business models by taking three provinces to stand for typical resource zones. The Internal return rate (IRR) is used to measure the economy, while the improved levelized cost of electricity (LCOE) is used to model the generation cost. Three business modes, namely pure producer (all generation sold to the grid), prosumer (self-use and the rest sold to the grid), and peer-to-peer trade (P2P, all generation traded via the grid) are studied. Results show that peer-to-peer trade is …
