An Application of Auditory Stimuli as Fading Prompts in Discrimination Training

Perlman, Neal S. 05 1900 (has links)
An experiment was conducted to examine the functionality of using auditory stimuli in isolation as fading stimuli. A review of the literature revealed very few reports regarding the usage of the auditory modality for fading purposes. The study employed auditory prompts as fading stimuli in the transfer of stimulus control across stimulus modalities, specifically, the transfer of stimulus control from auditory to visual stimulus properties. A single subject was employed for the experiment. The results were that the intensity of the auditory stimulus was an ineffective dimension to use for fading operations in the transfer of stimulus control across stimulus modalities, Further investigation is needed regarding the conditions that limit the transfer of stimulus control when auditory prompts are employed as fading stimuli.

Transfer technologií na Přírodovědecké fakultě Univerzity Karlovy v Praze / Transfer of Technologies at Faculty of Science, Charles University in Prague

Kadlec, Vojtěch January 2013 (has links)
This master thesis is focused on issues of technology transfer and cooperation between universities and application area. The aim is to disclose the barriers and factors that affect technology transfer and to identify the spatial pattern of cooperation. Theory of regional systems, concepts of triple helix, differentiated knowledge bases and models of learning are verified by a case study of Faculty of Science, Charles University in Prague. For the verification were used guided interviews with selected leaders of research teams at Faculty of Science. This thesis points out that the local specifics shape the character of cooperation. On the other hand comparison with research institutions in South Moravia shows that barriers affecting technology transfer are national. The comparison also shows that the existence of supporting institutions can positively affect the transfer of knowledge between academic and industry sphere. Key words: technology transfer, cooperation, personal contacts

Evaluation of Transfer of Technical Training: A Prototype

Stubbs, Carol A. (Carol Ann) 08 1900 (has links)
The degree of transfer of technical training to workplace behavior was evaluated using a Solomon Four-Group experimental design. Additionally, all groups received retrospective pretests. Subjects were 103 technicians in an electronics company. Supervisors rated technicians on behaviorally anchored rating scales which were developed and labeled as behavior description scales for simplicity. Analysis of variance revealed no effect for training nor pretest. A training-pretest interaction effect was revealed for one dimension (Communication with Support Groups). Analysis of covariance revealed main effects for pretesting for two dimensions (Problem Solving and Communication with Supervisor) and a pretest-training interaction-for one dimension (Problem Solving). Except for one dimension, t tests revealed no significant differences between traditional pretests and retrospective pretests, thus negating a hypothesized response shift bias.

A Porous Media Model for Sprinkler Wetting

Sipe, Joel E 08 April 2010 (has links)
A one-dimensional porous media model has been developed to investigate water based fire suppression. The model is for heat and mass transfer in porous materials subjected to external water sprays and radiant heating. In the model, heat transfer inside the material occurs by conduction, convection, and phase change. Mass transfer occurs by gas phase diffusion and convection in the liquid and gas phases. Convective mass fluxes are driven by pressure gradients according to Darcy’s Law. Boundary conditions that are appropriate for a range of cases are presented. The model was used, along with experiments, to investigate two scenarios relevant to water based suppression: spray wetting and radiant heating. Ceramic fiberboard samples were used as a test material. For the wetting tests, the model is shown to be able to reasonably predict the rate of water absorption into the samples. Radiant heating tests were conducted in the cone calorimeter with pre-wetted samples. For the heating tests, the model is shown to reasonably predict the drying behavior that would directly precede an ignition event.

Intramolecular Energy Transfer in Polychromophores that Utilize Peptide Bridging Groups

Ferguson, David C 05 May 2000 (has links)
Efficient singlet-singlet (SSET) and triplet-triplet (TTET) energy transfer between fluorenyl and either phenylbenzoyl or naphthyl chromophores in enantiomerically pure dipeptides occur via through-space intramolecular dipole-induced dipole (Förster-SSET) and electron exchange (Dexter-TTET) mechanisms as demonstrated by, UV-visible absorption, fluorescence, phosphorescence and laser flash photolysis measurements. Unprotected, optically pure 3-(2-fluorenyl)-L-alanine (8, Fla) and its C- and N-protected derivatives were synthesized using a modified Sorensen procedure, and were subsequently used for solution-phase synthesis of the dipeptides (9, Bpa-Fla and 10,Npa-Fla) and solid-phase synthesis of a 15-residue peptide (7). UV absorption spectra of the dipeptides indicate that the chromophores do not interact electronically in the ground state nor do their photophysical characteristics change when incorporated into the peptides. Dipeptide bichromophore fluorescence and phosphorescence results show efficient SSET (kSSET > 109 s-1) and TTET (kTTET > 104 s-1). Fluorescence and phosphorescence spectra produced by excitation at donor absorbance wavelengths show complete energy transfer in 9 and efficient energy transfer in 10. Donor-acceptor separation (transfer separation distance) was calculated from the spectral overlap of the donor fluorescence spectrum and the acceptor UV absorption spectrum using the Förster equation for energy transfer. With the spectral overlap value, assumed orientation of the chromophores in the dipeptide and the fluorescence quantum yield of the donor, a "critical" Förster transfer distance was calculated for the two dipeptides (9, 10) to be 14.6 Ã… and 15.1 Ã…, respectively. The actual distance calculated from dipeptide fluorescence spectra, using an assumed Förster distance was 9.1 Ã… and 8.7 Ã…, respectively. HyperChem MM3 modeling of the two dipeptides yielded an average inter-chromophore separation of 11 ±3 Ã…, comparable to the experimental values. Laser flash photolysis of the two dipeptides revealed near complete TTET. The spectral analysis of each dipeptide showed essentially 100% acceptor triplet present, although the donor in each case absorbed all or most of the incident light.

Purpose - The purpose of this study is to describe how to improve an organization’s desorptive capacity to facilitate knowledge transfer in transfer projects. Method - This research was conducted as a single case study, with an abductive approach, were the unit of analysis has been transfer projects. The empirical data collection has been qualitative and was conducted through 20 semi-structured interviews. The interviews were held at the case company with project managers, sub-project managers and project members to widen the experience of everyone involved in transfer projects. A thematic analysis was utilized to possess the empirical data. Result - We found that it is essential to evaluate critical factors in the identification of a transfer project and utilize managerial tools to facilitate the application of the knowledge transferred to the recipient. We have created a framework that show the correlations between the evaluation of the critical factors and the utilization of the managerial tools, categorized in organizational practices. Depending on the evaluation of the critical factors, resources need to be allocated to specific organizational practices. This will result in an improvement of an organization’s desorptive capacity. Theoretical contribution - This report contributes to the literature by filling the gap regarding how to improve organizations’ desorptive capacity to facilitate knowledge transfer in transfer projects. We have identified the critical aspects of desorptive capacity andcontributed with a framework that can be adapted by organizationsto improve their desorptive capacity. Managerial implications - The findings in this study have potential to increase the awareness among organizations about the initial phase of transfer projects and contribute to an increased understanding of how an organization can improve their desorptive capacity. It is recommended to utilize the presented framework in this report to take advantages of the correlations found between the critical factors and the organizational practices.

Lossless statistical data service over Asynchronous Transfer Mode.

Van Luinen, Steven M. January 1999 (has links)
Asynchronous Transfer Mode (ATM) can provide deterministic channels as required for real time signals, as well as statistical multiplexing. For this reason, ATM has been chosen as the underlying technology for providing a Broadband Integrated Services Digital Network (B-ISDN). Two main classes of services are expected to be supported over a B-ISDN. These classes are real-time services and data services. Data services include computer communications (Local Area Network (LAN) interconnections) and general non-real time traffic, such as file transfer and small transactions.The provision of data services over ATM are better served with statistical multiplexing, provided that the service is loss-free. For multiplexing to be loss-free and still statistical, while the maximum service rate is fixed, the multiplexer tributaries must be controlled in flow, to assure no overflow of the multiplexing buffer. Provision of a service over ATM is accomplished by an ATM layer. Transfer Capability (ATC).This thesis investigates and reports on the operating characteristics of an ATM layer Transfer Capability proposed to the International Telecommunications Union (ITU), and called Controlled Cell Transfer (CCT). CCT uses credit window based flow control on links and a quota based control in switches, and will give loss free statistical multiplexing for data. Other ITU defined ATCs are examined in regard to data service provision and compared with CCT. It is found that only CCT can provide a fast and at the same time efficient data service.The thesis also examines the impact that support of the CCT capability would have on an ATM switch, through determination of required functionality, and mapping of the required functions into a switch design. Finally, an architecture and implementation of an ATM switch is described that would support the CCT as well as the Deterministic Bit Rate (DBR) ++ / transfer capability, and would provide efficient data and real-time services.

Management of innovation networks in technology transfer.

Rampersad, Giselle January 2008 (has links)
Network management is a critical concept in innovation and technology transfer. Linkages among network members are fundamental in the innovation process which has been heralded for its contribution to wealth creation in economies increasingly characterized by both globalization and technological connectivity. Innovation networks involve relationships among members of governments, businesses and universities that collaborate continuously to achieve shared scientific goals. This study focuses on identifying the key management factors operating in such networks and on determining the process through which these lead to successful technology transfer. This is of increasing interest for many countries seeking to foster innovation, technology transfer and, in turn, international competitiveness. The study integrates the technology transfer and network research streams in order to provide a unique contribution towards understanding key network factors that are important in technology transfer. Extant technology transfer literature predominantly provides a perspective of a focal organization or, at best, that of inter-organisational relationships while its empirical investigation from a network perspective remains limited. In order to develop a more holistic network perspective, this study draws on the network literature and in particular that of the Industrial Marketing and Purchasing (IMP) group. Although neither a comprehensive network management theory nor suitable measures at the network level of analysis currently exist, the network literature is quickly evolving and has highlighted several concepts that contribute to achieving network outcomes, albeit in a conjectural fashion. Therefore, this study applies these concepts towards contributing to network management theory development in both the network and technology transfer fields. This study adopts a multi-method research approach. Qualitative exploratory research was necessary as concepts from the technology transfer and network management literatures were combined in a novel way. It was also essential in developing appropriate scales. Quantitative research then followed in order to test these scales by applying exploratory factor analysis and reliability testing. The developed scales were then employed to advance theory development, using confirmatory factor analysis via structural equation modelling. The study predominantly investigates networks within several industries that are relevant internationally and consistent with some of Australia’s national research priorities. Consequently, a pilot study was conducted in the wine industry to purify scales followed by full field work undertaken in the information and communications technology and biotechnology/nanotechnology industries. Common patterns that emerge within different industries strengthen theory development and lead to generalizations to other related industries while differences lead to industry-specific implications. A number of patterns were uncovered. Evidence was provided for the significant impact of power distribution, trust, coordination and harmony on achieving network outcomes in the ICT and the biotechnology/nanotechnology industries. While both communication and R&D efficiencies were deemed important in achieving network effectiveness, the specific relationships among these factors varied between industries. The study contributes to advancing theory on network management and offers practical management implications particularly for the industries under investigation. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1346750 / Thesis (Ph.D.) -- University of Adelaide, Business School, 2008
