The Relationship Between Emotional Content and Phonological Processing in Persian Speaking Children Who Stutter: A Study by Event-related Potential

Introduction: Emotion can contribute to the severity of stuttering, although the underlying mechanism is unknown. Event-related Potential (ERP) could be very helpful for assessing emotional processing in persons with stuttering. Our study aimed at the investigation of phonological processing for emotional and neutral words in Children Who Stutter (CWS) by ERP. Materials and Methods: Ten CWS were given 120 emotional and neutral words to read. Phonological processing was assessed by aloud reading task, while simultaneously ERP was recorded. The results were analyzed as behavioral (reaction time and accuracy) and electrophysiological (amplitude and topography). Results: There were significant differences in reaction time and accuracy between positive, negative, and neutral words (P<0.05). The electrophysiological data analysis showed significant differences for a minimum of amplitude in the left frontal area, for a maximum of amplitude in the right temporal area, and peak to peak distance in the left frontal area (P<0.05). Visual inspection suggested that recorded fluctuations have a bigger amplitude range for neutral words in all brain regions, except prefrontal, frontal and right frontal. Conclusion: Valence would affect behavioral measures. Generally, emotion facilitates word processing by reducing activity in anterior brain areas in phonological processing time.

Logistic Regression for Employability Prediction

Prediction is a conjecture about something which may happen. Prediction need not be based upon the previous knowledge or experience on the unknown event of interest in the future. But it is a necessity for mankind to foresee and make the right decisions to live better. Every person does predictions but the quality of the predictions differs and that differentiates successful persons and unsuccessful persons. In order to automate the prediction process and to make quality predictions available to every person, machines are trained to make predictions and such field comes under machine learning and later on deep learning algorithms. Various fields such as health care, weather forecasting, natural calamities, and crime prediction are some of the applications of prediction. The researchers have applied the field of prediction to see whether a model can predict the employability of a candidate in a recruitment process. Organizations use human expertise to identify a skilled candidate for employment based on various factors and now these organizations are trying to migrate to automated systems by harnessing the benefits of the exponential growth in the area of machine learning and deep learning. This investigation presents the development of a model to predict the employability by using Logistic Regression. A set of candidates was tested in the proposed model and results are discussed in this paper.

Preoperatory Anxiety in Patients Undergoing Cardiac Surgery

Anxiety is a feeling of discomfort produced in face of an unknown event, as an impending cardiac surgery, that can lead to inconveniences in the intervention and subsequent recovery. Being the purpose of this research to analyze pre-surgical anxiety, a descriptive cross-sectional study among patients undergoing cardiac surgery was carried out. Data about sociodemographic variables were collected and the level of anxiety prior to surgery was assessed using the STAI-S scale. Subsequently, descriptive data analyses were performed, relationships among variables were analyzed, and a binary logistic regression model was developed in order to analyze the role of the variables involved in the development of preoperative anxiety. Sixty subjects were finally included; more than 80% had a moderate to high level of anxiety. 26.7% underwent valve surgery and 47% underwent coronary artery bypass graft (CABG) surgery, in the latter case presenting higher levels of anxiety. Statistically significant relationships were found among the level of anxiety and (a) level of studies, (b) first surgical intervention, and (c) the rating given to their previous surgical experience. We concluded that preoperative anxiety in people undergoing cardiac surgery is high and yet it is an underestimated phenomenon. The relationship between the received information and their anxiety level is inversely proportional, so that people programmed for cardiac surgery should be provided with all the information they required, through an individualized intervention.

Materiality Matters When Organizing for Crisis Management

Sensemaking is the process to make sense of an unknown event. Research on the contribution of materiality in sensemaking is currently an area in need of further study. The Swedish system of crisis management puts the municipality in a key position when managing a crisis. Making the municipal situation room an interesting area for research. This study focuses on sensemaking in the municipal situation room during crisis management. The area of interest is when and why digital and/or non-digital resources are being used during sensemaking. The study contributes to an understanding of how sensemaking are performed in entanglement with the materiality provided. This is important for understanding needs of exercises and needs of resources in the situation room. The study was conducted as a qualitative study where interviews and observations were used to gather empirical evidence.

An ERP Study of Expectation Violation in a Social Comparison Context

Previous studies pay more attention to the cognitive control in classical cognitive conflict task but the time-course of the expectation violation in a social comparison context remains unknown. Event-related potentials (ERPs) were recorded to explore the electrophysiological correlates of expectation violation by using a reward feedback paradigm in a social comparison context. Results showed that: Expectation incongruent stimuli (EIS) elicited a more positive ERP deflection (P400-700) than did expectation congruent stimuli (ECS) between 400 and 700 ms. Furthermore, dipole source analysis revealed that the generator of P400-700 was localized near the posterior cingulate gyrus (PCC), which might be involved in the monitoring and controlling of reward expectation conflict (expectation violation). EIS also elicited a more negative ERP deflection (N1000-1500) than did ECS between 1,000 and 1,500 ms. The generator of N1000-1500 was localized near the parahippocampal gyrus, which might be related to unpleasant emotions induced by a lack of reward feedback.

Pollen morphology of Prototulbaghia Vosa: A comparative palynological study of the Southern African Alliaceae.

The Southern African Alliaceae Borkh. is represented by four genera (Allium L., Nothoscordum Kunth, Tulbaghia L. and Prototulbaghia Vosa) and 28 species. The pollen morphology of the endangered monotypic genus Prototulbaghia has not been described before. A comparative study of the pollen morphology of Prototulbaghia siebertii Vosa, Nothoscordum borbonicum Kunth, Tulbaghia simmleri P.Beauv. and T. violaceae Harv. is presented in this article. Scanning electron microscopy, as well as light microscopy, were used to examine the pollen. The pollen morphology of the species can be described as perprolate and monosulcate, and the surface sculpture as reticulate and heterobrochate. However, the pollen of Prototulbaghia siebertii displays a unique characteristic as the grains are folded in their breadth with the tips touching, hence causing the grain to display a triangular and disulcate appearance. It might be possible to ascribe this fold to the process of harmomegathy or a still unknown event that occurs during the development of the pollen grain. This phenomenon should be further investigated to determine the cause of folding and whether it is a unique taxonomic characteristic of this genus, and if it could be of evolutionary significance for the Alliaceae.
