The Use Of Asynchronous Video Communication To Improve Instructor Immediacy And Social Presence In A Blended Learning Environment, Jered Borup, Charles R. Graham, Andrea Velasquez

Faculty Publications

Instructors in a blended learning format struggle to find an effective balance between face-to-face instruction that is high in fidelity and online instruction that is high in flexibility. This chapter presents three cases where asynchronous video communication was used to help offer students instruction high in fidelity and flexibility. Although the medium for sharing asynchronous video varied between the three cases, findings indicate that video was a useful tool to improve instructor immediacy and/or social presence with a minimum amount of face-to-face instruction. The instructors in all three cases saw asynchronous video communications as an effective way to communicate with …

Lost In Translation: The Effects Of Incentive Compensation On Strategy Surrogation, Jongwoon Choi, Gary Hecht, William B. Tayler

Faculty Publications

To facilitate managers’ decision-making, firms develop strategic performance measurement systems that translate strategy into performance measures. Ideally, managers see measures for what they are: imperfect proxies for intangible strategic constructs. However, managers may fail to fully appreciate the fact that measures are merely representations of the strategic constructs, and act as though the measures were the construct of interest – a phenomenon we label surrogation. In this paper, we investigate whether and how the use of strategically-linked performance measures for compensation purposes affects managers’ propensity to exhibit surrogation. In accordance with the attribute substitution framework (Kahneman and Frederick 2002), we …

Short Interest As A Signal Of Audit Risk, Cory A. Cassell, Michael S. Drake, Stephanie J. Rasmussen

Faculty Publications

Motivated by evidence from the empirical accounting and finance literatures suggesting that short sellers target firms with suspect financial reporting, we investigate whether short interest provides a signal of the degree of audit risk. We find a positive association between audit fees and short interest (total shares sold short scaled by total shares outstanding) after controlling for other determinants of audit fees. This finding suggests that short interest is an indicator of audit risk that reflects information not captured by traditional client risk measures. We also find an increase in the magnitude of the association between audit fees and short …

Should Investors Follow The Prophets Or The Bears? Evidence On The Use Of Public Information By Analysts And Short Sellers, Michael S. Drake, Lynn Rees, Edward P. Swanson

Faculty Publications

We investigate whether short sellers and analysts differ in their use of information that is predictive of future returns. We find that open short interest is significantly associated in the expected direction with all eleven variables examined. In contrast, analysts tend to positively recommend stocks with high growth, high accruals, and low book-to-market ratios, despite these variables having a negative association with future returns. We then investigate the profitability of using short interest in trading. We find abnormal returns (1.11 percent per month) from a zero-investment strategy that (1) shorts firms with highly favorable analyst recommendations (buy signal) but high …

Third Way Architecture: Between Cybernetics And Phenomenology, S Murrani

School of Art, Design and Architecture

This article in its essence aims to challenge and unfold, each at a time, two different fields of methodology – cybernetics and phenomenology – that have direct effects on the product of being and the process of becoming in architectural discourse. Furthermore, this article suggests a third way philosophy for architecture that relates notions of post-phenomenology and technoscience, and considers both to be equally vital to development and speculation within current architectural discourse. First, the history of each of the two fields – cybernetics and phenomenology – will be unveiled with a focus on exploring their impact upon architecture in …

Understanding Streaming In Dictyostelium Discoideum: Theory Versus Experiments, J. C. Dallon, Brittany Dalton, Chelsea Malani

Faculty Publications

Recent experimental work involving Dictyostelium discoideum seems to contradict several theoretical models. Experiments suggest that localization of the release of the chemoattractant cyclic adenosine monophosphate to the uropod of the cell is important for stream formation during aggregation. Yet several mathematical models are able to reproduce streaming as the cells aggregate without taking into account localization of the chemoattractant. A careful analysis of the experiments and the theory suggests the two major features of the system which are important to stream formation are random cell motion and chemotaxis to regions of higher cell density. Random cell motion acts to reduce …

Organizational Centralization As Figurational Dynamics: Movements And Counter-Movements In The Gaelic Athletic Association, John Connolly, Paddy Dolan

Articles

In this paper we develop aspects of Elias’s figurational approach within organisational studies by using some of the core theoretical constructs as a model to explain organi­sational change through an empirical investigation of the dynamics of centralisation–decentralisation processes in an Irish sports organisation. Based on historical analysis, the paper documents the expanding interdependencies, figurational dynamics and shifting power balances which led to a gradual, non-linear movement towards greater integration and centralisation within the organisation.

Modelos Masculinos Y Violencia En Sanctuary Y Crónica De Una Muerte Anunciada, Cesar Valverde

Scholarship

This essay analyzes how two novels, William Faulkner’s Sanctuary and Gabriel Garcia Marquez’s Chronicle of a Death Foretold, present masculine models that juxtapose power and violence during times of social crisis. Both novels present violent masculinities that overcome peaceful masculinities, in conflicts that result in murders and rapes; but rather than acuse the individuals responsible for the violent acts, the texts point out the social mechanisms that inexorably move the authors of the crimes. In both works we also see violence against women and resulting public deaths of men wrongly accused, which happen due to an inability to adapt to …

Crisis Discourse In Ireland: Enterprise Discourse On An Edge, Brendan O'Rourke

Conference papers

The 2007 international economic crisis may have begun in capitalism’s heartland with credit default swops and sub-prime mortages, nevertheless some of its most dramatic manifestations have been at the edge. In Europe, the peripheral economies of Iceland, Greece and Ireland have manifested crises that have shaken Europe to the core, and generated crisis discourse that may well prove central. Certainly previous talk of crisis seem to have been key to political change processes in the past (Hay, 1996; Mårtenson and Lindhoff, 1998).While there has been some initial analysis of the discursive response to the economic crisis (Hartz, 2010; O’Rourke, 2010) …

How Can We Nurture And Develop Creativity In First Year Design Students, Kerry Meakin

Theses

This research paper investigates the perceptions of first year third level design students regarding their creative thinking and use of creative strategies, while studying a first year design based curriculum in an Institute of Technology in Dublin. The research was conducted in a three-phase, sequential project. The first phase, questioned twenty seven students by issuing anonymous questionnaires to gather data on their methods of incubating design ideas, if they experienced any levels of anxiety when doing so, and their satisfaction levels in their design and creative abilities. Literature was reviewed to discover the attributes of those we perceive as creative …

Religiosity, Self-Control, And Antisocial Behavior: Religiosity As A Promotive And Protective Factor, Robert D. Laird, Loren D. Marks, Matthew D. Marrero

Faculty Publications

Three hypotheses with the potential to provide information on the role of religiosity as a promotive and protective factor in early adolescence were tested. Adolescents (N = 166, M age = 13 years, 49% female, 49% European American, 45% African American) and mothers reported their own personal importance of religion and the frequency of their attendance of religious services. Greater mother importance and attendance was associated with greater adolescent importance and attendance. Mother importance was indirectly linked to adolescent antisocial behavior through adolescent importance. Less adolescent importance and attendance were associated with low self-control and low self-control was associated …

Obtaining Speech Assets For Judgement Analysis On Low-Pass Filtered Emotional Speech, John Snel, Charlie Cullen

Conference papers

Investigating the emotional content in speech from acoustic characteristics requires separating the semantic con- tent from the acoustic channel. For natural emotional speech, a widely used method to separate the two channels is the use of cue masking. Our objective is to investigate the use of cue masking in non-acted emotional speech by analyzing the extent to which filtering impacts the perception of emotional content of the modified speech material. However, obtaining a corpus of emotional speech can be quite difficult whereby verifying the emotional content is an issue thoroughly discussed. Currently, speech research is showing a tendency toward constructing …

Corned Beef: An Enigmatic Irish Dish, Máirtín Mac Con Iomaire, Pádraic Óg Gallagher

Conference papers

Corned beef and cabbage, which is consumed in America in large quantities each Saint Patrick’s Day (17th March), is considered by most Americans to be the ultimate Irish dish. However, corned beef and cabbage is seldom eaten in modern day Ireland. It is widely reported that Irish immigrants replaced their beloved bacon and cabbage with corned beef and cabbage when they arrived in America, drawing on the corned beef supplied by their neighbouring Jewish butchers, but not all commentators believe this simplistic explanation . This paper will trace the origins and history of corned beef in Irish cuisine and chart …

Community-Based Internet Usage Policy Development, Mashael Alhawsah

Students Learning with Communities

The Internet is a tool for learning and obtaining a vast amount of information, but it is a tool which also has associated problems. The number of risks associated with the internet has been increasing both in number and in danger. As a result, protection measures must be developed to minimize the risks. One of the most important groups of such measures are Internet Usage Policies. An Internet Usage Policy addresses the problem by providing a set of guideline to be followed which minimize the risks. This dissertation investigates the development of Internet Usage Policy with the assistance of the …

Friction Stir Lap Welded Advanced High Strength Steels: Microstructure And Mechanical Properties, M. Ghosh, K. Kumar, R. S. Mishra

Materials Science and Engineering Faculty Research & Creative Works

Friction stir welding was carried out under different heat input and cooling rates to produce lap joints between high strength martensitic steel sheets. the microstructure of the welds was characterized, and microhardness was evaluated. Joint efficiency was determined by lap shear test. Variation in processing conditions governed total heat input, peak temperature and cooling rate during friction stir welding. Weld nugget microstructure depended principally on cooling rate. the slowest cooling rate promoted ferrite-pearlite and the fastest cooling rate resulted in martensite formation in the weld nugget. the weakest region of all the joints was the heat affected zone, which consists …

A Stress-Strain Model For A Two-Phase Ultrafine-Grained Aluminum Alloy, P. S. De, J. Q. Su, R. S. Mishra

Materials Science and Engineering Faculty Research & Creative Works

Two-phase ultrafine-grained (UFG) aluminum alloys with different precipitate and low-angle boundary distributions were examined for their monotonic stress-strain behavior. Precipitates in combination with low-angle grain boundaries were found to determine the deformation micro mechanism. It is proposed that thermally activated vacancy movement plays a central role in this regard. the experimental stress-strain curves matched well with the trend predicted by a modified Blum-Zheng model based on vacancy-assisted dislocation annihilation mechanism. © 2010 Acta Materialia Inc.

Hollow Hydroxyapatite Microspheres For Controlled Delivery Of Proteins, H. Fu, M. N. Rahaman, D. E. Day

Materials Science and Engineering Faculty Research & Creative Works

Hollow hydroxyapatite (HA) microspheres were prepared by reacting solid microspheres of a lithium-calcium-borate glass (106-150 microns) for 2 days in K₂HPO₄ solution (0.02 M; 37°C) and evaluated as a controlled delivery device for a model protein, bovine serum albumin (BSA). the as-prepared HA microspheres had a hollow core with a diameter equal to 0.6 the external diameter, a surface area of V100 m²/g, and a mesoporous shell wall (pore size of ≈13 nm). after loading the hollow HA microspheres with a solution of BSA, release of the BSA into a medium of phosphate-buffered saline (PBS) …

Robustness Analysis Of Slow Learning In Iterative Learning Control Systems, John R. Singler, Douglas A. Bristow

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This paper examines robust stability and robust transient growth in Iterative Learning Control (ILC). It is well known that small perturbations in system dynamics can result in very large transient growth of some ILC systems. Even larger perturbations can result in instability. One ad hoc technique commonly employed to improve robustness is to slow the learning rate by reducing the learning filter gain or lowpass filtering the error signal. Here, pseudospectra analysis is used to analyze the robustness of ILC algorithms with slow learning. It is found that robustness bounds can be increased and transient growth decreased with decreasing learning …
