A preliminary observation on the effect of audio-visual speech perception in voiced cognates by Cypriot-Greek learners of English
Get PDFThis study examines the use of audiovisual cues in the perception of sound contrasts which have a different phonemic status in the listeners’ L1 and L2. Voice-voiceless cognates differing in the distinctiveness of their visual gestures (/p/-/b/, /t/-/d/, and /k/-/g/) were presented to CG (Cypriot-Greek) learners of English in audio, visual, and audiovisual modalities. Overall identification rates were significantly higher audiovisually in the cases where the auditory and visual information matched (bimodal congruent condition) than in the audiovisual condition in which auditory and visual information did not match (bimodal incongruent condition) or in the audio or video alone condition for either contrast. The results point to the multisensory speech-specific mode of perception, which plays an important role in alleviating the majority of moderate-to-severe L2 difficulties. CG listeners’ success seems to depend upon the ability to relate what they see to what they hear
Visualization Challenges of Virtual Reality 3D Images in New Media Environments
Get PDFThis paper proposes a three-dimensional image visualization process to face-drawing three-dimensional image reconstruction algorithm to obtain the data field with three-dimensional space, using color adjustment based on global color correction and local Poisson fusion to optimize the splicing seams between the texture color blocks and updating the visualization technology of three-dimensional images. Divide the digital display design and create a virtual reality visualization display using 3D modeling in combination with the new media environment. Propose design steps to visualize virtual reality three-dimensional images in the new media environment by combining the key algorithms of three-dimensional image visualization from the previous section. Combined with the application of new media displaying 3D images, the concept of artifact shape in reconstructed images is proposed to analyze the quality of 3D image reconstruction by taking the Herman model and Sheep-Logan model as the research object. Test experiments are conducted to examine the visual impact of texture mapping algorithms, and different sampling intervals are set to measure the drawing time of 3D reconstruction. For the data size and number of pictures of other organizations, the processing time of the 3D image reconstruction algorithm based on surface drawing is no more than 2s. The denser the sampling points are, the higher the degree of fitting, the more complete the preservation of isosurface information is, the finer the effect of 3D reconstruction, and the higher the quality of the image
Exploring the Role of Perceived Supervisor Support: A Serial Mediation of Approach Job Crafting and Thriving at Work in Enhancing Job Satisfaction
Get PDFThe purposeof this study is to explore the underlying mechanism of approach job crafting and thriving at work that explain the relationship between perceived supervisor support and job satisfaction amongpublic sector employees. Drawing on job demand and resource model and organization support theory, the study aims to investigate the proposed serial mediation in public sector employees in Pakistan. By examining the sequential relationships among perceived supervisor support, approach job crafting, thriving at work, and ultimately job satisfaction, this research seeks to provide a comprehensive understanding of the dynamics within public sector organizations and offer insights for enhancing employee satisfaction. Based on cross sectional data from 369 public sector employees,Smart PLS 4andstructural equation modeling (SEM) wereemployedto analyze the data and study the serial mediation effect. Strong empirical evidence was found for all the proposed hypotheses. The findings indicated that stronger perceptions of supervisor support are associated with higher levels of job satisfaction among employees. Furthermore, approach job crafting and thriving at work mediate this relationship, highlighting theemployee behavior to actively shape theirroles and experiences at work. The findings show a path for public sector employees to capitalize on the antecedents to employee job satisfaction. Furthermore, it is suggested that public sector organizations should encourage active supervisor support to promote employee job satisfaction. In doing so, it is important to ensure that the employees are provided a workplace that pursues and encourages approach job crafting for enhanced levels of job satisfaction through thriving at work. This study expands theresearch on approach job crafting and sheds light on important conditions under which perceived supervisor support promotes job satisfaction in public sector employees in Pakistan. The study holds importance for public sector employees, supervisors and the public sector departments at large

Understanding the machined material’s behaviour in electro-discharge machining (EDM) using a multi-phase smoothed particle hydrodynamics (SPH) modelling
Get PDFElectro-discharge machining (EDM) has been extensively employed for machining hard alloys, and its simulations have been widely conducted using finite element analysis (FEA). However, the majority of mesh-based models depended on forecasting the crater profile only based on the temperature gradient, without offering detailed data regarding the machined material properties. It is crucial to understand the behaviour of the machined material in order to accurately assess the flushing efficiency, analyse the wear on the electrode, and examine the interaction between the debris generated during machining and the remaining workpiece. This is done to ensure that no recast material is left behind after the EDM process. For the first time, a meshless smoothed particle hydrodynamics multi-phase model was implemented to gain practical insights and comprehensively understand a very intricate phenomenon that occurs within a very short time. Additionally, this approach is utilised to investigate the characteristics of the materials being machined. We utilised our SPH model to simulate both the capacitance- and transistor-based EDM of Ti–6Al–4V and AISI304 steel. Our simulation considered the temperature-dependent thermal properties and latent heats of the materials. The accuracy of our model was confirmed by comparing its results with experimental, analytical, and finite element analysis (FEA) results. The machined material was observed during its removal from the surface, and the dimensions of the resulting crater, as well as its aspect ratio and the rate at which the material was removed, were predicted with an error ranging from 2 to 22%. This error is far lower than that of the typical finite element (FE) prediction. This model lays the groundwork for a more complex model that will more accurately represent EDM and other similar manufacturing processes

Military First Responders in Sri Lanka: Post-Crisis Psychosocial Challenges and Treatment Recommendations by Mental Health Professionals
Get PDFPurpose – This research explored perspectives of civilian and military based mental health professionals regarding mental health challenges, influencing factors, and treatment considerations for military first responders in Sri Lanka, after they’ve been exposed to crisis events.
Methodology – Twenty-nine mental health professionals from Sri Lanka (14 civilian and 15 military based) engaged in a semi-structured interview to share their experiences and recommendations in treating military first responders from Sri Lanka army and navy.
Key findings – Thematic Analysis yielded two main categories of data:) 1) factors influencing the impact of exposure to crisis event and 2) factors influencing effective interventions; for first responders in the Sri Lanka military. . These two categories were further analysed as themes and subthemes, based on factors which amplify, buffer against, and/or has a variable impact on trauma symptomology, and factors external to military first responders, which could impact their recovery efficiency. .
Originality – This study is one of the first to explore mental health challenges and treatment considerations for military first responders in South Asia, through the perspective of civilian and military based mental health professionals
