Rusli, Pinky. "The Effect of Control Source and Control Framing on Employee Effort." UKnowledge, 2017. http://uknowledge.uky.edu/accountancy_etds/8.

Abstract:

Prior research suggests that controls can negatively impact the motivation of employees to exert effort and that the detrimental effects of controls depend on control source. That is, controls cause more adverse behavior when employees attribute the source of control implementation to their manager’s decision than when the source of control implementation is beyond their manager’s authority. This study uses experiments to investigate whether the behavioral effects of controls depend not only on control source, but also on control framing, by which managers can frame the control implementation

Abstract:

A frame refers to a decision maker’s perception of a decision problem. Frames affect outcomes of decisions and are partially controlled by how decision problems are formulated. This study investigated the effect of framing alternatives in a privacy decision as gaining or losing value, need to make an effort and gaining control in an online environment. Also a structure among the many effects found in earlier research concerning privacy in the context of Internet based services was sought. For these purposes two experiments and one survey were conducted at a university in Sweden. The study incl

Abstract:

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand functions the benefits of integration with inventory control are substantially increased due to the price dynamics. We also provide some analytical results for this more complex model. We thus conclude that integrated pricing/inventory models could repeat the success of revenue management in practice if reference price effects are included in the demand model an

Abstract:

Quality of Service (QoS) in real-time media applications can be defined as the ability to guarantee the delivery of packets from source to destination over best-effort networks within some constraints. These constraints defined as the QoS metrics are end-to-end packet delay, delay jitter, throughtput, and packet losses. Transporting real-time media applications over best-effort networks, e.g. the Internet, is an area of current research. Both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) have failed to provide the desired QoS. This research aims at developing app

Abstract:

Quality of Service (QoS) in real-time media applications is an area of current interest because of the increasing demand for audio/video, and generally multimedia applications, over best effort networks, such as the Internet. Media applications are transported using the User Datagram Protocol (UDP) and tend to use a disproportionate amount of network bandwidth as they do not perform congestion or ﬂow control. Methods for application QoS control are desirable to enable users to perceive a consistent media quality. This can be accomplished by either modifying current protocols at the transport l

Abstract:

Neurocognitive models of anxiety highlight the importance of attentional control and prefrontal control mechanisms and posit that anxiety is characterised by impaired effectiveness and efficiency during inhibition, especially under high cognitive load and in the presence of threat-related stimuli (Eysenck, Derakshan, Santos, & Calvo, 2007). The current thesis utilised behavioural, oculomotor, pupillary, and neurophysiological measures to examine the inefficient/ineffective inhibitory control and increased cognitive effort in high (vs. low) anxious individuals in the presence and absence of

Abstract:

This dissertation is concerned with the problem of the exact pole-placement by minimum control effort using state and output feedback for linear multivariable systems. The novelty of the design lies in obtaining a direct transformation of the system matrices into a modified controllable canonical form. Two realizations are identified, and the algorithms to obtain them are derived. In both cases, the transformation matrix has some degrees of freedom by tuning a scalar or a set of scalars within the matrix. These degrees of freedom are utilized in the solution to reduce further the norm of the s

Abstract:

Hemiparetic stroke survivors often produce asymmetric forces when performing bilateral tasks, despite their perception that the forces are equal. It has been hypothesized that this asymmetry is due to the use of effort – as opposed to force magnitude – as the controlled parameter in bilateral force-matching. That is, human perception of force and weight seems to be based more on the intensity of the outgoing motor command than on afferent feedback. This thesis is focused around an experiment that investigated whether this sense of effort (SOE) plays a dominant role in the control and perceptio

Abstract:

Le soudage par friction malaxage (FSW) est un procédé de soudage innovant pour les matériaux à bas point de fusion (aluminium, cuivre…). Il a été breveté en 1992 par l’organisme anglais The Welding Institute (TWI). Depuis plusieurs années, celui-ci se développe dans l’industrie en cherchant à réduire son coût d’investissement. Le principe du FSW est de réaliser un cordon de soudure grâce à un outil animé d’un mouvement de rotation et d’avance. Les niveaux d’efforts et de précision requis contraignent à l’utilisation de machines cartésiennes de grande envergure. L’utilisation des robots industr

Abstract:

Age affects hearing and cognitive abilities. Older people, with and without hearing impairment (HI), exhibit difficulties in hearing speech in noise. Elderly individuals show greater difficulty in segregating target speech from distracting background noise, especially if the noise is competing speech with meaningful contents, so called informational maskers. Working memory capacity (WMC) has proven to be a crucial factor in comprehending speech in noise, especially for people with hearing loss. In auditory scenes where speech is disrupted by competing speech, high WMC has proven to facilitate

Abstract:

This dissertation reports on two supplemental instruction implementations in courses with high failure rates. In study one, 27 ultra-short on-line tutorials were created for Principles of Accounting II students (N = 426). In study two, 21 tutorials with a similar design were created for Elementary Statistics students (N = 1,411). Accounting students were encouraged by their instructor to use the resource, but statistics students only saw a brief demonstration by the researcher. Neither course gave students credit for using the tutorials. In study one, 71.4% of the accounting students used the

Abstract:

Stress is the most common reason for sick leave in Sweden today. The physical demands are less in today’s work life, but the psychological demands have increased, resulting in increased stress related ill-health. The aim with the current study was to gain an understanding in how individuals that has been or are on stress-related sick leave experience the social support received at the work place and where they experienced that the primary responsibility for the sick leave was. Nine participants from self-help groups for stress was interviewed with a qualitative hermeneutic approach. The interv
