Catalytic Combustion Of Ethyl Acetate, Tuğba Gürmen Özçeli̇k, Süheyda Atalay, Erden Alpay

Turkish Journal of Chemistry

The catalytic combustion of ethyl acetate over prepared metal oxide catalysts was investigated. CeO, Co_2O_3, Mn_2O_3, Cr_2O_3, and CeO-Co_2O_3 catalysts were prepared on monolith supports and they were tested. Before conducting the catalyst experiments, we searched for the homogeneous gas phase combustion reaction of ethyl acetate. According to the homogeneous phase experimental results, 45% of ethyl acetate was converted at the maximum reactor temperature tested (350 °C). All the prepared catalysts were tested in order to find the best catalyst for the complete combustion of ethyl acetate. According to the results, all these catalysts produced higher conversion rates than that …

The Clinical Utility Of Categorical And Dimensional Subclassification Of Schizophrenia: An Investigation Using Prototypic And Nonprototypic Cases, Megan A. Hasenwinkel

All-Inclusive List of Electronic Theses and Dissertations

The heterogeneity of schizophrenia and how best to delineate subtypes has been a problem since schizophrenia was first recognized. Limitations with the current subtypes of schizophrenia include low temporal stability, poor interrater reliability, lack of support for validity, and frequent use of the "undifferentiated" subtype. As an alternative, researchers have proposed dimensional models for subclassification of schizophrenia. These include Crow's Type I/Type II (positive symptoms/negative symptoms), Nicholson and Neufeld's severity of disorder/severity of symptoms model, the three dimension model (negative, disorganized, psychotic) proposed in the DSM-IV, as well as lesser-known four and five dimension models. One important criterion for evaluating …

Port Competitiveness In North East Asia : An Integrated Fuzzy Approach To Expert Evaluations, Gi-Tae Yeo

Plymouth Business School Theses

Despite the fact that the Northeast Asia (NEA) region, which had four of the top five and 20 of the top 30 container ports in the world in 2003, can be regarded as holding a central position in liner shipping and the handling of container cargo volumes, very little research has been done into the evaluation of its port competitiveness (EPC). For this reason, the EPC in NEA can be regarded as a problematic and urgent issue to be solved, and worthy of academic attention. From this aspect, this research set out to attempt to address the above issue by …

The Characteristics Of Sino-Taiwanese Joint Ventures In The People's Republic Of China, Chen-Yu James Liu

Plymouth Business School Theses

The main objective of this thesis is to shed light on the characteristics and performance of Sino-Taiwanese joint ventures (JVs) in the People's Republic of China and in particular to investigate the role played by guanxi (interpersonal relationships) in their formation and in the way they function. The research shows that guanxi enhances the effectiveness of Taiwanese joint venture partners by overcoming unanticipated external environmental factors and enabling them to deal with the complex internal managerial issues associated with the Chinese market. The different political and economic relations between Taiwan and China make the joint venture entry strategy attractive to …

Impact Of Culture On Stock Market Development And Corporate Governance, Walaa Wahid Eldin Elkelish

Plymouth Business School Theses

This study takes a step forward to explore the dynamic relationship between cultural values and stock market development in the United Kingdom, during the period 1991- 2004. Cultural values are represented by the cultural model of Hofstede (1980) which consists of five dimensions, which are: power distance, uncertainty avoidance, individualism, masculinity and time horizon. Stock market developmenti s representedb y four indicators, which are: stock market activity, size, liquidity and concentration. Empirical results, using structural equation modelling (SEM), show that some cultural values have significant relationships with stock market development indicators. Power distance has a significant negative relationship with stock …

The Adoption Of Internet Technologies By Independent Hotels In The Uk, Wai Mun Lim

Plymouth Business School Theses

The growth of the technology and its range of possible uses have made it a necessity for independent hoteliers to examine their use of the internet, specifically its effectiveness for marketing and distribution purposes. It is widely recognised that the independent hotel sector makes up the bulk of the hotel industry in the UK and often do not have the resources or desire to keep up with new technologies. This study scrutinizes, evaluates and establishes the factors that influence the decision to adopt a range of internet technologies for marketing and distribution within the UK Independent hotel sector. The conceptual …

Socio-Economic Aspects Of Commercial Ports And Wharves In Southwest England: A Grounded Theory Approach To Regional Competitiveness, Sarah Tuck

Plymouth Business School Theses

The Southwest Region, as defined by the SW Regional Development Agency, forms an extended peninsula with a coastline of 1,020 km, the longest of any region in England. All along this coastline are fishing ports, commercial ports, small wharves, closed ports, ferry ports and leisure ports. Amongst the smallest are a dozen tidal ports, tiny harbours and rocky wharfs that still maintain a commercial trade of local and environmental significance. According to most theories of port development these ports should close, being forced out of business by larger, more efficient ports. Semi-structured interviews were conducted with fifteen people who were …

Direct Formation Of H_2o_2 From H_2 And O_2, Meltem Yildiz, Ayşe Ni̇lgün Akin

Turkish Journal of Chemistry

The direct combination of hydrogen and oxygen to form hydrogen peroxide in liquid media with prepared catalysts was carried out in a slurry reactor at atmospheric pressure and room temperature. An O_2/H_2 ratio of 2:1 with a 50 mL/min flow rate was used in these experiments. Catalyst activity measurements were tested by the iodometric titration method using KMnO_4. The results are discussed based on the effects of support material, catalyst preparation method, reaction time, and medium (type of halide and acid) on hydrogen peroxide yield in direct oxidation of hydrogen to produce hydrogen peroxide. Our results showed that the catalytic …

Partial Separability And Partial Additivity For Orderings Of Binary Alternatives, Md. Abul Bashar

Theses and Dissertations (Comprehensive)

In Multiple-Criteria Decision Analysis (MCDA), a good way to find the best alternative is to construct a value function that represents a Decision Maker’s (DM) preferences. For multidimensional alternatives, an additive value function is easiest to work with because it assesses the alternatives in a simple and transparent manner. A DM’s preferences over consequences on a subset of the set of criteria may or may not depend on consequences on the rest of the criteria. Preferences that are free from all such interdependence are said to be separable. The existence of an additive value function implies separability and, when consequences …

The Role Of Christian Faith In The Acculturation And Identity Development Of Chinese Immigrant Youth, Lynn Chyi-Ing Liao

Theses and Dissertations (Comprehensive)

Immigration is a life-altering experience that significantly contributes a context for identity formation, a critical and salient task during the years of late adolescence and emerging adulthood. Religion as a influential factor in the lives of youth has often been overlooked and considering the transnational quality of Christianity, it may have an important role to play in the acculturation and identity development of immigrant youth.

In this qualitative study, I chose to interview Chinese immigrant youth aged 18-23, who are recent immigrants and self-identify as Christian. The central idea of this exploratory inquiry is that each individual interprets experiences of …

Criminal Jumping On And Off The Curb - Discretion And The Idea Of An Impartial And Independent Police Force, W. Wesley Pue

All Faculty Publications

This paper presents a commentary on the idea of independence of the police, arguing that notions of independence are complicated considerably when the reality of police discretion is taken into account. The notion of colourability is identified as central (where goals not unlawful in themselves are pursued for unlawful reasons - eg. to vicitimize one's political foes) as is the possibility of police powers being deployed lawfully in the strict sense, but in a fashion that is nonetheless constitutionally improper.

The Problem Of Official Discretion In Anti-Terrorism Law: Comment On Khawajah, W. Wesley Pue, Robert Russo

All Faculty Publications

This paper assesses the first judicial ruling on key provisions of the Anti Terrorism Act. Rutherford J.'s ruling struck down provisions creating a motive requirement in the definition of terrorist activity while upholding the overall structure of the act against challenges on the basis of overbreadth and vagueness. A fault-line divides the two sides of the ruling. On one side the court looked to the lived-experience of legal rules, concluding that including motive requirements would mislead officials in the direction of improper and unconstitutional racial or religious profiling. On the other side of the fault-line the court restricted itself to …

Assurance Services As A Substitute For Law In Global Commerce, Margaret M. Blair, Cynthia A. Williams, Li-Wen Lin

All Faculty Publications

In this article we examine the rapid emergence and expansion of a private-sector compliance and enforcement infrastructure that we believe may increasingly be providing a substitute for public and legal regulatory infrastructure in global commerce, especially in developing countries where rule of law is weak and court systems are absent or inadequate. This infrastructure is provided by a proliferation of performance codes and standards, and a rapidly-growing global army of privately-trained and authorized inspectors and certifiers that we call the "third-party assurance industry." The growth in the third party assurance business has been phenomenal in the last decade. The business …

A Prisoners' Charter? Reflections On Prisoner Litigation Under The Canadian Charter Of Rights And Freedoms, Debra Parkes

All Faculty Publications

This paper examines over twenty years of prisoner litigation under the Canadian Charter of Rights and Freedoms, beginning with a brief consideration of the social and political context for prisoners into which the Charter was entrenched in 1982, before moving on to consider a variety of successful and unsuccessful prisoners' Charter claims. The author notes some ways in which the impact of the Charter has been diminished at the prison walls, including through a lack of full and meaningful access by prisoners to courts or other means of independent review of prison decisions and conditions, as well as by the …

Privacy, Identity And Security, Benjamin J. Goold

All Faculty Publications

This paper examines the relationship between security, surveillance, privacy and identity, both in the context of legislation such as the Anti-terrorism Act and the PATRIOT Act, and also in the light of ongoing changes in how that personal information is gathered, processed and used. It is argued that prevailing notions of privacy — and the legal frameworks that aim to protect privacy interests — are ill-suited to defending individuals from an increasingly sophisticated array of surveillance and data processing techniques, which enable information to be acquired and shared at almost zero-cost and which threaten to establish the ‘categorical identity’ as …

Hearing The Sexual Assault Complaints Of Women With Mental Disabilities: Consent, Capacity, And Mistaken Belief, Janine Benedet, Isabel Grant

All Faculty Publications

Women with mental disabilities experience high rates of sexual assault. The authors trace the history of the criminal law's treatment of cases involving such acts in order to evaluate whether the substantive law of sexual assault is meeting the needs of this group of women. In particular, the authors focus on the legal issues of consent, capacity, and mistaken belief. The authors situate this discussion in the context of current debates in feminist and critical disability theory, grounding the theory in scholarly research on sexual assault of women with mental disabilities. In considering the law's treatment of sexual violence against …

Hearing The Sexual Assault Complaints Of Women With Mental Disabilities: Evidentiary And Procedural Issues, Janine Benedet

All Faculty Publications

When a woman with a mental disability makes a complaint of sexual assault, she must confront a criminal trial process that was not designed in contemplation of her as a witness. The requirements of repeated testimony under oath and the ability to be cross-examined are not always well-suited to the particular needs and capacities of women with mental disabilities. These problems are magnified by the tendency to infantilize women with mental disabilities, thereby diminishing their credibility and depicting them as hypersexual when they engage in any sexual activity. These stereotypes also manifest themselves in the application of evidentiary rules relating …

Individualism And Collectivism In America: The Case Of Gun Ownership And Attitudes Toward Gun Control, Katarzyna Celinska

Publications and Research

A number of sociologists and cultural psychologists claim that the United States is a predominantly individualistic country. This article uses a unidimensional index of individualism and collectivism to analyze one of the most debated sociopolitical issues in America: gun ownership and gun control. It tests the hypothesis that the widespread gun ownership in the United States and prevailing attitudes toward gun control represent competing individualistic and collectivistic cultural traditions, respectively. The findings indicate that the index is one of the predictors of gun ownership and of attitudes about gun permits.

Fifth Millennium Anthropomorphic Figurines In Southeastern And Central Anatolia: Comparative Museum Research., Ellen H. Belcher

Publications and Research

The Halaf cultural horizon occurred during the fifth millennium B.C. (uncalibrated) and extended throughout upper Mesopotamia, including southeastern Anatolia. Halaf material culture is well-known for its imaginative and beautifully made architecture, polychrome-painted pottery, geometric stamp seals and figurines. The regional character and variation of Halaf figurine assemblages however, is poorly understood, particularly in southeastern Anatolia. My research and study of these figurines reveals distinct southeastern Anatolian styles and technologies, some of which demonstrate direct connections to central Anatolia.

This article presents preliminary conclusions from a comparative analysis of contemporaneous anthropomorphic figurines belonging to the Halaf and Chalcolithic cultures …

The Arab Charter On Human Rights 2004, Susan M. Akram

Faculty Scholarship

The Boston University International Law Journal is publishing, for the first time, an English version of the 2004 Arab Charter on Human Rights. A very brief review of how the 2004 Arab Charter came into being introduces this English translation. The drafting history of the Arab Charter on Human Rights begins in 1960. In that year, members of the Union of Arab Lawyers (the oldest NGO in the Arab world) requested the League of Arab States (created in 1945) during their meeting in Damascus to adopt an Arab Convention on Human Rights. Eight years later, participants in the first meeting …

Digital Watermarking And Self-Authentication Using Chirp Coding, Jonathan Blackledge

Articles

This paper discusses a new approach to ‘watermarking’ digital signals using linear frequency modulated or ‘chirp’ coding. The principles underlying this approach are based on the use of a matched filter to provide a reconstruction of a chirped code that is uniquely robust, i.e. in the case of very low signal-to-noise ratios.

Chirp coding for authenticating data is generic in the sense that it can be used for a range of data types and applications (the authentication of speech and audio signals, for example). The theoretical and computational aspects of the matched filter and the properties of a chirp are …

Modelling And Computer Simulation Of Radar Screening Using Plasma Clouds, Jonathan Blackledge

Articles

Following a brief introduction on the principles of screening an aerospace vehicle using a plasma, we develop models for the Impulse Response Functions (IRFs) associated with microwave (Radar) back-scattering from a strong and weakly ionized plasma screen. In the latter case, it is shown that the strength of the return signal is determined by an IRF that is characterised by the simple negative exponential exp(−σ₀t/Є₀) where σ₀ is the average conductivity of the plasma, Є₀ is the permittivity of free space and t is the two-way travel time. For a weakly ionized plasma, the …
