Investigations Of The Tribological Effects Of Engine Oil Dilution By Vegetable And Animal Fat Feedstock Biodiesel On Selected Surfaces, Sultana Mahbuba Shanta

College of Graduate Studies: Theses & Dissertations

Biodiesels have become attractive alternative fuel to replace traditional fossil fuels. Biodiesels can be used in diesel engines with no major modification, but its use leads to some degree of engine oil dilution because of biodiesel leaking and scrapping to engine oil pan. Biodiesels can be made from vegetable and animal fat feedstocks. Therefore, the fatty acid methyl ester components of biodiesel may vary upon these sources of feedstock. In this thesis work, engine oil is diluted with vegetable (canola oil, peanut oil and soybean oil biodiesel) and animal (chicken fat) feedstock biodiesels at known percentages and these mixtures are …

Detecting Outliers In Multiple Linear Regression, Ehab A. Mahmood

Journal of Economics and Administrative Sciences

It is well-known that the existence of outliers in the data will adversely affect the efficiency of estimation and results of the current study. In this paper four methods will be studied to detect outliers for the multiple linear regression model in two cases : first, in real data; and secondly, after adding the outliers to data and the attempt to detect it. The study is conducted for samples with different sizes, and uses three measures for comparing between these methods . These three measures are : the mask, dumping and standard error of the estimate.

Journal of Economics and Administrative Sciences

This research has come out with that, function-based responsibility accounting system has harmful side – effects preventing it of achieving its controlling objective, that is, goal congruence, which are due to its un integrated measures, its focus on measuring measurable behaviors while neglecting behaviors that are hardly measured, and its dependence on standard operating procedures. In addition, the system hypotheses and measures are designed to fit previous business environment, not the current environment. The research has also concluded that the suggestive model, that is, activity-based responsibility accounting is designed to get ride of harmful side – effects of function-based responsibility …

Dynamic Algorithm (Drblts) And Potentially Weighted (Wbp) To Estimate Robust Regression Using A Bootstrap Technique (Comparative Study), Taha Hussein Ali

Journal of Economics and Administrative Sciences

Bootstrap is one of an important re-sampling technique which has given the attention of researches recently. The presence of outliers in the original data set may cause serious problem to the classical bootstrap when the percentage of outliers are higher than the original one. Many methods are proposed to overcome this problem such Dynamic Robust Bootstrap for LTS (DRBLTS) and Weighted Bootstrap with Probability (WBP).

Four Perspectives On Architectural Strategy, C. Jason Woodard, Joel West

Research Collection School Of Computing and Information Systems

A recurring theme in the literature on technology and organizations is the concept of mirroring, which posits a duality between technological and organizational design decisions. In this paper we highlight a second, orthogonal duality between components and interfaces: designers of both products and organizations must decide what information to hide within component boundaries and what to expose to other designers. Although the component-interface duality appears in many settings, it presents especially vexing strategic challenges in the design and production of complex digital artifacts. We present a typology of four interlinked perspectives on these kinds of strategic design problems, and discuss …

An Effective Approach For Topicspecific Opinion Summarization, Binyang Li, Lanjun Zhou, Wei Gao, Kam-Fai Wong, Zhongyu Wei

Research Collection School Of Computing and Information Systems

Topic-specific opinion summarization (TOS) plays an important role in helping users digest online opinions, which targets to extract a summary of opinion expressions specified by a query, i.e. topic-specific opinionated information (TOI). A fundamental problem in TOS is how to effectively represent the TOI of an opinion so that salient opinions can be summarized to meet user’s preference. Existing approaches for TOS are either limited by the mismatch between topic-specific information and its corresponding opinionated information or lack of ability to measure opinionated information associated with different topics, which in turn affect the performance seriously. In this paper, we represent …

Gender Differences In Virtual Collaboration On A Creative Design Task, Shu Schiller, Fiona Nah, Brian Mennecke, Keng Siau

Research Collection School Of Computing and Information Systems

Collaboration is an important activity in every organization because it fundamentally affects work processes and organizational outcomes. Diversity adds complexity to the mechanism of virtual teams because teams routinely operate virtually by spanning temporal, geographic, national, and cultural boundaries. One important way to decode such complexity is to understand gender differences and their impacts on virtual modes of collaboration. In this research, we examine gender differences and how they influence outcomes and attitudes on virtual collaboration in the context of team gender composition. Phase one of our study involved male-male dyads and female-female dyads that collaborated virtually in Second Life. …

Kovesi And The Formal And Material Elements Of Concepts, T. Brian Mooney, Mark Nowacki, John N. Williams

Research Collection School of Social Sciences

In his seminal work Moral Notions, Julius Kovesi presents a novel account of concept formation. At the heart of this account is a distinction between what he terms the material element and the formal element of concepts. This paper elucidates his distinction in detail and contrasts it with other distinctions such as form-matter, universal-particular, genus-difference, necessary-sufficient, and open texture-closed texture. We situate Kovesi’s distinction within his general philosophical method, outlining his views on concept formation in general and explain how his theory of concept formation is applied in moral philosophy.

Going Beyond The Multicultural Experience-Creativity Link: The Mediating Role Of Emotions, Chi-Ying Cheng, Angela K. Y. Leung, Tsung-Yu Wu

Research Collection School of Social Sciences

This research examines the mediating role of emotions implicated in the multicultural experience—creativity link. We propose that when individuals are dealing with apparent cultural contradictions upon encountering two cultures simultaneously, mentally juxtaposing dissonant cultural stimuli could lower positive affect or increase negative affect, which could in turn induce a deeper level of cognitive processing of cultural discrepancies and inspire creativity. Two studies compared dual cultural exposure versus single cultural exposure among bicultural Singaporeans (Study 1) and compared self-relevant (jointly presenting local and foreign cultures) versus self-irrelevant (jointly presenting foreign cultures only) dual cultural exposure among monocultural Taiwanese (Study 2). As …

Cracks In The Empire: Reflections Of French Journalists And Authors On The Crisis In 1930s Indochina, Henri Copin, Tobias Rettig

Research Collection School of Social Sciences

The events of the early 1930s in Vietnam left an important legacy to France's literature of enquiry and protest. Writers, essayists and journalists enquired on behalf of their audiences, and in the process developed France's littérature coloniale. By showing an interest in the colonial 'other' and identifying discrepancies between imperial ideology and colonial reality, they formed a new body of thought. This new colonial humanism arguably changed metropolitan sensibilities towards the French civilizing mission. Nevertheless, while they are critical of colonial abuses and in favour of reforms, the authors discussed in this paper do not really question the French colonial …

Special Issue: Revisiting And Reconstructing The Nghê Tinh Soviets, 1930-2011, Tobias Frederik Rettig

Research Collection School of Social Sciences

The seven papers presented here constitute the first collective effort in a Western language to revisit the Nghe Tinh Soviets of 1930–31. The Nghe Tinh movement, its name a compound of two neighbouring provinces in the north-central part of the French protectorate of Annam, not only occupies a special place in the history of the early Vietnamese Communist Party (VCP) but also became a site for animated debate on the causes of agrarian unrest that produced two of the most influential books in South East Asian Studies: James Scott’s Moral Economy of the Peasant (1976); and Samuel Popkin’s The Rational …

Research Collection Yong Pung How School Of Law

The Court of Appeal (CA) judgment in Muhammad bin Kadar v Public Prosecutor created quite a stir in Singapore. The case pertained to a murder involving two suspects, and its resolution took almost six years, with many twists and turns as to the actual facts. The CA attributed the confusion in part to questionable practices adopted by the police and the prosecution at various points in the proceedings, and reserved strong words for them in its judgment. It also established new requirements for the prosecution regarding its duty to the court to disclose relevant material not favourable to the case …

Including The Excluded: Communitarian Paths To Cosmopolitanism, Eduard Jordaan

Research Collection School of Social Sciences

Cosmopolitanism is frequently criticised for overlooking the situatedness of morality and the importance of solidarity in their aspiration to global justice. A number of thinkers take these criticisms seriously and pursue ‘a communitarian path to cosmopolitanism’. Four such approaches are considered. All four view morality and justice as grounded in a specific social setting and hold that justice is more likely to result if there is some ‘we-feeling’ among people, but are simultaneously committed to expanding the realm of justice and moral concern to beyond national boundaries. To enable the theorisation of an expanded realm of situated justice and moral …

Academic Tenure: Defining Scholarship In The Health Professions, Kimberly Mathieu Coulton

College of Graduate Studies: Theses & Dissertations

Higher education institutions in the United States grant academic tenure to junior faculty based on teaching, service, and scholarship. Traditionally, scholarship is defined as original research that is demonstrated by reports of scientific findings, peer-reviewed journal publications and presentations. However, workload issues, insufficient institutional support and ambiguity in tenure guidelines often hinder the scholarly endeavors of university faculty seeking tenure. The roles and responsibilities of faculty in the allied health professions are unique in that they are also involved in the provision of patient care, the development of community partnerships and the task of addressing vital workforce needs. A broader …

The purpose of this research was to determine the biological stability of five prebiotics in a variety of food matrices when processed under various conditions. A biological test, the prebiotic activity assay, was used to test for stability of six food products (muffin, cookie, granola bar, breakfast cereal, sports drink, and bread) containing five different prebiotics (fructooligosaccharides (FOS), inulin, galactooligosaccharides …

Identification And Characterization Of Putative Allergens In Pecan Species, Jelena Spiric

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The identification and characterization of soluble pecan proteins was found to be qualitatively dependent on the chemical characteristics of the extraction buffer that also had a significant influence on the total protein content of an extract. The ionic strength of the extraction buffer had a greater impact on protein extractability than pH. A high salt phosphate buffer (0.01 M PBS, 1M NaCl, pH 7.2) was used as an optimal extraction solution that allowed remarkable detection of clinically relevant allergens.

The 2S albumin family of seed storage proteins has been shown to be one of the most stable allergens, thus potentially …
