An Approach To Improve International Maritime Security Through The Coordination Between The Imo Instruments And The Proliferation Security Initiative (Psi) Regime, Song Y. Yi Dec 2012

An Approach To Improve International Maritime Security Through The Coordination Between The Imo Instruments And The Proliferation Security Initiative (Psi) Regime, Song Y. Yi

World Maritime University Dissertations

This dissertation is a study on the Proliferation Security Initiative (PSI) which is a global effort through which nations deliberately interdict carriage of illicit WMD-related substances commuting States and non-States actors. Given its flexibility as an “activity” rather than an organization, the initiative has gained supports from more than 102 countries since its interception in 2003. Now, in its 10th year, and despite boasting over 100 participants, the PSI continues to face legal, political and structural challenges. By looking into the realities of PSI activities, the paper attempts to explore some of the key challenges, with its practical means of …


How Exclusive Is The Exclusive Economic Zone : Contemporary Analysis Of The United Nations Convention On The Law Of The Sea 1982, Oscar Garrido-Lecca Hoyle Dec 2012

How Exclusive Is The Exclusive Economic Zone : Contemporary Analysis Of The United Nations Convention On The Law Of The Sea 1982, Oscar Garrido-Lecca Hoyle

World Maritime University Dissertations

International agreements as maritime international laws are the main tool for the sustainable development of the protection and employment of the oceans and seas. Dealing with maritime issues that arise every day, requires a highly focused analysis and establishment of principles and rules to prevent these problems. Globalization provides the opportunity to carry out business around the world and its development has created transnational companies. Technological advances have allowed extended opportunities to explore and exploit the natural resources of the seas, with the resulting risk of these resources becoming extinct if such activities are not controlled. In this scenario, the …


Activity Of Enzyme Trypsin Immobilized Onto Macroporous Poly(Epoxy-Acrylamide) Cryogel, W Johnson, Ymm Makame Dec 2012

Activity Of Enzyme Trypsin Immobilized Onto Macroporous Poly(Epoxy-Acrylamide) Cryogel, W Johnson, Ymm Makame

Tanzania Journal of Science

Bovine pancreatic trypsin has been covalently immobilized onto monolithic polyacrylamide cryogels with epoxy functionality (Epoxy-MPAAGs). The covalent immobilization of trypsin onto Epoxy-MPAAGs was achieved through incorporation of ethylenediamine-glutaraldehyde spacers on the cryogels’ surfaces. The immobilization yield and the influence of pH and temperature conditions on the activity of the immobilized trypsin were assessed by using the hydrolysis of a low molecular weight substrate, N-α-benzoyl-D, L-arginine-p-nitroanilide (BAPNA). Optimal pH and temperature values of 9 and 50 °C, respectively, were established for both the immobilized trypsin and the free trypsin. Activity measurements from the native trypsin before immobilization and the residual free …


Computational Chemistry Capacity Building In An Underprivileged Context: Challenges, Outcomes And Perspectives, L Mammino Dec 2012

Computational Chemistry Capacity Building In An Underprivileged Context: Challenges, Outcomes And Perspectives, L Mammino

Tanzania Journal of Science

Computational chemistry is a fast developing branch of modern chemistry, focusing on the study of molecules to enable better understanding of the properties of substances. Its applications comprise a variety of fields, from drug design to the design of compounds with desired properties (e.g., catalysts with specific actions) and to ample overlaps with nanotechnology. However, despite its relevance, the presence of computational chemistry research in Sub-Saharan Africa is still scarce, practically absent in many institutions. Bridging the gap with the other continents requires the identification of capacity building options that may enable a rapid growth. The recent experience at the …


Using Metaphors As A Tool For Creative Strategic Sense-Making, Tomaž Kolar Dec 2012

Using Metaphors As A Tool For Creative Strategic Sense-Making, Tomaž Kolar

Economic and Business Review

This paper investigates the use of metaphor as a valuable tool in encountering contemporary challenges in marketing strategy development. A review of the literature indicates how traditional approaches pay insufficient attention to the fact that marketing strategy development rests largely on the processes of intuitive and symbolic thinking. The first part of the paper establishes creative strategic thinking, which includes these processes as a key imperative in marketing strategy development. To show how metaphors can serve as a tool in encountering some of the challenges identified the second part examines the functions of metaphors. The final part of the paper …


Cannibalism, Ecocriticism, And Portraying The Journey, Simon C. Estok Dec 2012

Cannibalism, Ecocriticism, And Portraying The Journey, Simon C. Estok

CLCWeb: Comparative Literature and Culture

In his article "Cannibalism, Ecocriticism, and Portraying the Journey" Simon C. Estok discusses the ways early modern preoccupation with cannibalism is at once rooted in and reflective of an ecophobic environmental ethics. Looking both at descriptions of metaphoric and literal cannibalism, Estok shows that imagining cannibalism was central to the travel narrative and to its investments in writing the center and the periphery, the human and the nonhuman, the acceptable and the repugnant — binaries which reveal ethical positions, not only toward people, but, more broadly, toward the natural environment. Estok argues that it is relevant to discuss the discourse …


Gulliver, Travel, And Empire, Claude Rawson Dec 2012

Gulliver, Travel, And Empire, Claude Rawson

CLCWeb: Comparative Literature and Culture

In his article "Gulliver, Travel, and Empire" Claude Rawson analyzes Jonathan Swift's Gulliver's Travels as a central document of European intellectual history. Rawson focuses on the relationship between ethnicity and human identity and asks what constitutes humanity and how individual groups qualify (or not) for human status. Posing teasingly as a "parody" of travel books, it is both a series of voyages and an ethnically widening arc of moral exploration as Book Four at once expresses an ambivalent perception of the Irish under English rule and extends to what Swift/Gulliver calls "all Savage Nations" and ultimately takes in what Swift …


The Slave Trade In The Work Of Fox, Johnson, And Spielberg, Ya-Huei Lin Dec 2012

The Slave Trade In The Work Of Fox, Johnson, And Spielberg, Ya-Huei Lin

CLCWeb: Comparative Literature and Culture

In her article "The Slave Trade in the Work of Fox, Johnson, and Spielberg" Ya-huei Lin analyzes Paula Fox's The Slave Dancer (1973), Charles R. Johnson's The Middle Passage (1990), and Amistad, the 1997 film directed by Steven Spielberg based on the true event of 1841. Lin's examination of these three texts is an attempt to clarify the event's narration in the context of Walter Benjamin's historical materialism. Further, Lin explores what Louis Althusser proposes in "A Letter on Art" as to how the texts at hand make one see the ideology from which they are located. The authors' …


Reimagining "Tense And Tender Ties" In García's Monkey Hunting, Yu-Fang Cho Dec 2012

Reimagining "Tense And Tender Ties" In García's Monkey Hunting, Yu-Fang Cho

CLCWeb: Comparative Literature and Culture

In her article "Reimagining 'Tense and Tender Ties' in Garcia's Monkey Hunting" Yu-Fang Cho analyses Cristina García's re-narration of transnational histories of the multi-racial, multi-generational Chinese Cuban family in Monkey Hunting (2003) as a critical project that recasts developmental immigrant narratives primarily set in the United States as part of the emerging cultural archive of global migrations. Drawing on recent scholarship on comparative racialization, especially Ann Laura Stoler's formulation of "tense and tender ties" as a method, Cho examines how García's family saga unsettles the temporal and spatial logics of Euro-American modernity through the deployment of cyclical narrative structure …


Power And Representation In Anglo-American Travel Blogs And Travel Books About China, Stefano Calzati Dec 2012

Power And Representation In Anglo-American Travel Blogs And Travel Books About China, Stefano Calzati

CLCWeb: Comparative Literature and Culture

In his article "Power and Representation in Anglo-American Travel Blogs and Travel Books about China" Stefano Calzati presents a comparative analysis between two travel books and two travel blogs written by Anglo-American travellers about China. The assumption is that travel books and travel blogs, being two differently mediated forms of travel writing, share some similarities: they are "autodiegetic narratives" and they bear a (cross)cultural potential. Through a Multimodal Critical Discourse Analysis I investigate how Anglo-American travel writers represent themselves and Chinese people as to what extent the definition of travel writing is medially affected; 2) to what extent the cross-cultural …


Negra D'America Remond And Her Journeys, Sirpa A. Salenius Dec 2012

Negra D'America Remond And Her Journeys, Sirpa A. Salenius

CLCWeb: Comparative Literature and Culture

In her article "negra d'America Remond and Her Journeys" Sirpa A. Salenius analyzes Sarah P. Remond's travels to Europe. Remond, an African American born free in Salem, Massachusetts in 1826 into an abolitionist family, was a successful lecturer on abolitionism in the United States before traveling to England in 1859. During her anti-slavery lecture tour there, she also became involved in promoting women's rights thus enlarging the scope of her social and political agenda to embrace both racial and gender oppression. Subsequently, she studied in London, graduating as a nurse from London University College before moving to Italy where …


Drone Federalism: Civilian Drones And The Things They Carry, Margot E. Kaminski Dec 2012

Drone Federalism: Civilian Drones And The Things They Carry, Margot E. Kaminski

Publications

Civilian drones are scheduled to be permitted in the national airspace as early as 2015. Many think Congress should establish the necessary nationwide regulations to govern both law enforcement and civilian drone use. That thinking, however, is wrong. This Essay suggests drone federalism instead: a state-based approach to privacy regulation that governs drone use by civilians, drawing on states’ experience regulating other forms of civilian-on-civilian surveillance. This approach will allow necessary experimentation in how to best balance privacy concerns against First Amendment rights in the imminent era of drone-use democratization. This Essay closes by providing some guidance to states as …


Expectations In The Foreign Language Classrooms: A Case Study, Olha Ketsman Dec 2012

Expectations In The Foreign Language Classrooms: A Case Study, Olha Ketsman

The Qualitative Report

Research shows the strong correlation between expectations and student achievement across different disciplines. However, little research has been conducted regarding the role of discipline specific classroom expectations in student academic achievement. This multiple instrumental case study discusses expectations in two rural Spanish high school classrooms in which teachers produce d the highest achieving students. The data was collected through classroom observations, one-on-one audiotaped interviews with teachers and exploration of instructional materials. The study provides insights about the role of expectations in foreign language classrooms and offers examples of foreign language pedagogical practices that reflect high expectations. The study concludes that …

Information-Seeking 2.0:The Effects Of Informational Advantage, Laura Robinson

Sociology

This article begins to shed light on the use of new media for information acquisition and assessment. Drawing on the subject of a high school diploma for high school students, the article examines high achievers committed to academic excellence in preparation for college. However, while they share the same educational goals, they do not have access to the same informational resources. Information on advancing access to new media, traditional media, and social networks. Examination reveals how these disparities in the field of information are important Students with positive credentials adopt autonomous strategies vis-à-vis the assessment of information for both schoolwork …


Participatory Budgeting: Diffusion And Outcomes Across The World, Brian Wampler, Janette Hartz-Karp Dec 2012

Participatory Budgeting: Diffusion And Outcomes Across The World, Brian Wampler, Janette Hartz-Karp

Political Science Faculty Publications and Presentations

In this special issue of the Journal of Public Deliberation, multiple faces of Participatory Budgeting programs are revealed. The articles demonstrate that there is no standardized set of “best practices” that governments are adopting, but there are a broader set of principles that are adapted by local governments to meet local circumstances. Adopt and adapt appears to be the logic behind many PB programs.


Dharmakirti, Davidson, And Knowing Reality, Lajos Brons Dec 2012

Dharmakirti, Davidson, And Knowing Reality, Lajos Brons

Comparative Philosophy

If we distinguish phenomenal effects from their noumenal causes, the former being our conceptual(ized) experiences, the latter their grounds or causes in reality "as it is" independent of our experience, then two contradictory positions with regards to the relationship between these two can be distinguished: either phenomena are identical with their noumenal causes, or they are not. Davidson is among the most influential modern defenders of the former position, metaphysical non-dualism. Dharmakirti' strict distinction between ultimate and conventional reality, on the other hand, may be one of the most rigorously elaborated theories of the opposite position, metaphysical dualism. Despite this …


Benevolent Government Now, Howard J. Curzer Dec 2012

Benevolent Government Now, Howard J. Curzer

Comparative Philosophy

Mencian benevolent government intervenes dramatically in many ways in the marketplace in order to secure the material well-being of the population, especially the poor and disadvantaged. Mencius considers this sort of intervention to be appropriate not just occasionally when dealing with natural disasters, but regularly. Furthermore, Mencius recommends shifting from regressive to progressive taxes. He favors reduction of inequality so as to reduce corruption of government by the wealthy, and opposes punishment for people driven to crime by destitution. Mencius thinks government should try to improve the character of the population by preventing or relieving poverty, by setting a good …

Leadership Contestations, Succession, And Stability In Malaysia And Indonesia, Yang Razali Kassim Dec 2012

Leadership Contestations, Succession, And Stability In Malaysia And Indonesia, Yang Razali Kassim

Asia-Pacific Social Science Review

While Southeast Asia is generally stable, political leadership in two regional states is going through a period of uncertainty. The leaderships in Malaysia and Indonesia are undergoing some stress as they face the challenges of transition. Najib Razak, who was appointed Prime Minister of Malaysia in 2009, is due to call a general election to win his first mandate from the people. Najib’s return to office is likely, though this is not a certainty, as Malaysian politics have become more unpredictable. Indonesia’s President Susilo Bambang Yudhoyono is to step down in 2014 at the end of his second and mandatory …
