Examining The Relationship Between Employer Knowledge Dimensions And Organizational Attractiveness: An Application In A Military Context, Filip Lievens, Greet Van Hoye, Bert Schreurs

Research Collection Lee Kong Chian School Of Business

This study uses Cable and Turban's (2001) employer knowledge framework as a conceptual model to formulate hypotheses about a broad range of possible factors affecting the attractiveness of an organization (i.e. armed forces) among potential applicants (576 high-school seniors). Results show that gender, familiarity with military organizations, perceptions of job and organizational attributes (task diversity and social/team activities), and trait inferences (excitement, prestige, and cheerfulness) explained potential applicants' attraction to military organizations. Relative importance analyses showed that trait inferences contributed most to the variance, followed by job and organizational attributes, and employer familiarity. Finally, we found some evidence of interactions …

Agro-Pastoralists’ Wrath For The Prosopis Tree: The Case Of The Il Chamus Of Baringo District, Kenya, D. Layne Coppock, Abdillahi A. Aboud, Phillip K. Kisoyan

Environment and Society Faculty Publications

Indigenous to Peru, Chile, and Argentina, the woody plant called Prosopis juliflora (also known by the American common name of “Honey Mesquite”) has spread world-wide in recent decades, including rangelands throughout Latin America, North America, south and central Asia, Australia, and sub-Saharan Africa. A species known for rapid establishment, high adaptability, and fast rates of growth, its dispersal has primarily been a consequence of intentional introduction by well- meaning “technical experts” who wanted to provide a new source of fodder, fuel wood, or a means to combat desertification in arid and semi-arid lands. One problem, however, is that unless Prosopis …

Linking Pastoralists And Exporters In A Livestock Marketing Chain: Recent Experiences From Ethiopia, D. Layne Coppock, Solomon Desta, Getachew Gebru, Seyoum Tezera

Environment and Society Faculty Publications

The Boran of southern Ethiopia have been traditionally viewed as unwilling or unable to engage in large scale, commercialized livestock trade. Here we report on the creation of a new livestock marketing chain from the Borana Plateau to export outlets largely serving the Gulf States. Since 2003 various meetings and exchange tours were organized by collaborating agencies and PARIMA to directly link pastoral producers with livestock exporters and policy makers. This occurred against a backdrop of growing export demand for small ruminants, rapid development of private export industry, formation of well-trained pastoral marketing groups (often dominated by women), and provision …

Consumer Preferences For High-Tech Product Forms: Converged Or Separate? Evolution Of Technology & Reversal Of Preferences, Jin K. Han, Seh-Woong Chung, Seok Sohn Yong

Research Collection Lee Kong Chian School Of Business

With the surging popularity and growing availability of convergence products (e.g., camera phones, all-in-one PDAs) in high-tech product categories, consumers now face another dilemma in their purchase consideration: which product form converged, stand-alone, or both? This study sets out to investigate pattern(s) of consumer preferences for product form along the evolution of technology trajectories. In two experiments, we find that, at low levels of technological performance, consumers show an overwhelming preference for the converged product form over the dedicated counterpart; whereas, at a higher technological performance level, the pattern of preferences is reversed. Furthermore, we observe that a preannouncement of …

Determinants Of Intra-Day Stock Price Change And Asymmetric Information, Christopher Hian Ann Ting

Research Collection Lee Kong Chian School Of Business

This paper presents a synthesized model of asymmetric information. An empirical analysis of more than 1,400 NYSE common stocks shows that trade direction is more important than volume in revealing the asymmetry. There is also evidence to suggest that signed duration reflects informed trading activity. We use the proposed measure of information asymmetry to study daily changes in the level of informed trading and find that earnings announcements narrow the information gap between the informed and the uninformed. On average, information asymmetry is largest at the beginning of the trading day and it decreases monotonically toward the closing bell. More …

E-Government Capabilities And Crisis Management: Lessons From Combating Sars In Singapore, Shan Ling Pan, Gary Pan, Paul R. Devadoss

Over the past two decades, it has leveraged its IT infrastructure for economic development and transformed its public services. The SARS outbreak in 2004 turned into a national health crisis because it spread rapidly and the medical community had little knowledge of how to treat the new mutation of the corona virus. Yet, several Singaporean government agencies utilized the e-Government infrastructure and related resources to quickly bring the outbreak under control. In particular, the government?s IT infrastructure streamlined communications, information exchange, and data flow, and significantly eased collaboration …

Incidence Of Larval And Pupal Parasitoids Of Lepidoptera In Uganda With Special Reference To New Associations, I. Rwomushana, S. Kyamanywa, A. J. Ngi-Song, C. O. Omwega

All Peer-Reviewed Publications

Cotesia flavipes Cameron (Hymenoptera: Braconidae) was introduced in Uganda in 1998 for the biological control of the old association cereal stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). However there is little information on whether this parasitoid will attack new association Lepidoptera, which in turn may have implications on its efficacy on Ch. partellus. This study investigated the incidence of introduced Co. flavipes on Ch. partellus, and new association lepidopteran species and associated effects on its efficacy. Parasitism levels for Co. flavipes in several locations varied between 13.7-34.8% and 1.5-18.8% on Ch. partellus and new association hosts, respectively. Implications for biological control …

The Influence Of Humanism On The Handwriting Of Michelangelo Buonarroti, Robert J. Tallaksen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The handwriting of Michelangelo Buonarroti underwent a distinct and permanent change between 1497 and 1502. The handwriting of his early letters of 1496 and 1497 is merchantescha, the gothic cursive mercantile script which he would have learned at school. The later handwriting is cancellarescha, a humanistic cursive. It is present in letters, contracts, memoranda, records of accounts, and in annotations on drawings. Both scripts as written by Michelangelo are analyzed paleographically and are compared to examples from instructional writing books of the period. The impossibility of evolution from one script to the other is demonstrated through analysis of the scripts …

The Impact Of Points Of Impasse On Conflict Escalation During The Special Education Conflict Resolution Process, Deedra Jane Lundeen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current literature reveals the disparity between the knowledge that strong parent-school partnerships are integral to planning and implementing educational programming for exceptional children, and the ability of parents and school personnel to identify and deescalate conflict when it occurs. Several studies acknowledged variables that helped build and maintain strong parent-school collaboration, and identified factors that escalated or de-escalated parent conflict. However, the research is sparse regarding factors that impact points of impasse on conflict escalation between parents and school districts during the special education conflict resolution process. Such information could provide stakeholders with deeper insight into the dynamic aspects of …

An Ontological View Of The Kingdom Of God In Gutierrez, Segundo, Boff, And Sobrino, Hugo Monroy

Electronic Theses and Dissertations

The great majority of the four hundred and fifty million people in Latin America are poor and oppressed. Presenting the gospel to them as good news is a challenge for any theologian. Theologians' lives are at risk in most places regardless of the ideology they endorse. Jon Sobrino escaped death because he was lecturing out of the country when a military squad came into his home and killed his six companions and the two women who helped them. To serve in a context of poverty and death, theologians need more than church doctrines, creeds, and traditions to sustain them in …

Robust And Efficient Localization Techniques For Cellular And Wireless Sensor Networks, Haseebulla M. Khan

Computer Science Theses & Dissertations

Localization in wireless networks refers to a collection of tasks that, collectively, determines the location of a mobile user, striving to hide the effects of mobility from the user and/or application. Localization has become an important issue and has drawn considerable attention, as many applications including E-911, cargo tracking, locating patients, location-sensitive billing, etc., require knowledge of the location of user/objects. It was realized, quite a while back, that extending emergency 911-like services (E-911) to continually growing mobile population is one of the extremely important localization applications. The bulk of the proposed solutions to emergency location management in wireless environments …

Supporting Awareness In Heterogeneous Collaboration Environments, Vijayanand Bharadwaj

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rapid technological advancements have made it possible for humans to collaborate as never before. However demands of group work necessitate distributed collaboration in very heterogeneous environments. Heterogeneity as in various applications, platforms, hardware and communication infrastructure. User mobility, lack of availability and cost often make imposing a common collaboration environment infeasible. Awareness is essential for successful collaboration. Awareness is a key design criterion in groupware but often collaboration occurs with applications not designed to support useful awareness. This dissertation deals with the issue of effective group awareness support in heterogeneous environments.;Awareness propagation is effective if the appropriate amount of information, …

Cellular Mechanisms Of Luteal Regression In The Bovine Corpus Luteum (Cl), Aritro Sen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The corpus luteum (CL) is a transient endocrine gland that produces progesterone (P4) for the establishment and maintenance of pregnancy. In absence of pregnancy, timely regression of the CL is essential for normal ovarian cyclicity. Several factors are known to participate in luteal regression. In this study, two factors, PGF2 alpha and endothelin (ET-1) are being studied. Protein kinase C (PKC) and calcium are the two main intracellular mediators of PGF2 alpha. The role of ET-1 in the regulation of luteal regression is unclear. The early CL is insensitive to the luteolytic actions of PGF2 alpha and the cellular mechanism(s) …

Water Quality Changes Of Underground Mines In Northern West Virginia, Jennifer Demchak

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage (AMD) is a serious problem from both abandoned surface and underground mines, and about 10,000 km of streams have been impacted by AMD in the northeastern U.S. (Pennsylvania, Maryland, Ohio, and West Virginia). Streams in the region have shown improvement over time and this improvement has been partly attributed to reclamation of mined sites and natural attenuation of AMD impacts. This study was initiated to determine the water quality changes from underground mines over time in northern West Virginia.

Assessing The Effectiveness Of Descriptive And Experimental Analyses To Identify Variables Influencing Problem Behavior In Domestic Dogs, Susan D. Kapla

Graduate Theses, Dissertations, and Problem Reports (ETD)

Problem behavior in dogs is a concern for pet owners. Many contemporary approaches to intervention first involve a process of diagnosis and classification which is often structural in nature. An accurate diagnosis is considered essential for effective treatment, however, outcome data validating the efficacy of this procedure are dubious. The success of strategies used to assess and treat behavior problems that identify behavioral function in humans (functional assessment), however, suggests the potential utility of such techniques in the assessment and treatment of behavior problems in dogs. Therefore, two separate assessments were conducted to identify and manipulate variables affecting problem behavior …
