Neuroendocrine control of a dynamic communication signal

Multiple physiological systems regulate the electric communication signal of the weakly electric gymnotiform fish, Brachyhypopomuspinnicaudatus. Fish were injected with neuroendocrine probes which identified pharmacologically relevant serotonin (5-HT) receptors similar to the mammalian 5-HT1AR and 5-HT2AR. Peptide hormones of the hypothalamic-pituitary-adrenal/interrenal axis also augment the electric waveform. These results indicate that the central serotonergic system interacts with the hypothalamic-pituitaryinterrenal system to regulate communication signals in this species. The same neuroendocrine probes were tested in females before and after introducing androgens to examine the relationship between sex steroid hormones, the serotonergic system, melanocortin peptides, and EOD modulations. Androgens caused an increase in female B. pinnicaudatus responsiveness to other pharmacological challenges, particularly to the melanocortin peptide adrenocorticotropic hormone (ACTH). A forced social challenge paradigm was administered to determine if androgens are responsible for controlling the signal modulations these fish exhibit when they encounter conspecifics. Males and females responded similarly to this social challenge construct, however introducing androgens caused implanted females to produce more exaggerated responses. These results confirm that androgens enhance an individual's capacity to produce an exaggerated response to challenge, however another unidentified factor appears to regulate sex-specific behaviors in this species. These results suggest that the rapid electric waveform modulations B. pinnicaudatus produces in response to conspecifics are situation-specific and controlled by activation of different serotonin receptor types and the subsequent effect on release of pituitary hormones.

Questioning the merits and demerits of electronic communication in Social Work

This paper examines the social dynamics of electronic exchanges in the human services, particularly in social work. It focuses on the observable effects that email and texting have on the linguistic, relational and clinical rather than managerial aspects of the profession. It highlights how electronic communication is affecting professionals in their practice and learners as they become acculturated to social work. What are the gains and losses of the broad use of electronic devices in daily lay and professional, verbal and non-verbal communication? Will our current situation be seriously detrimental to the demeanor of future practitioners, their use of language, and their ability to establish close personal relationships? The paper analyzes social work linguistic and behavioral changes in light of the growth of electronic communication and offers a summary of merits and demerits viewed through a prism emerging from Baron���s (2000) analysis of human communication.

Crisis communication in politics: forgiveness as image restoration tool

Crisis communication is a widely treated field. There are lot of works and guides which provide helpful information in order to face crisis situations successfully (Alcat, 2005, Benoit, 1997) and articles about case studies (Nespereira, 2014, Blaney y Benoit 2001). Nonetheless, most of times, these guides are focused on business or corporations (Abeler, 2010) and there are not such information about crisis communications in politics (Gaspar e Ibeas, 2015). The field is smaller if we speak about forgiveness as restoration image tool in politics (Harris 2006). Despite all, we live in ���forgiveness era��� as Krauze said (1998) where people demand to politicians to apologize when they have mistakes (Harris et al. 2006:716). So, we will try to make an approach to forgiveness in politics as a image restoration tool and analyze its capabilities in order to face crisis management.

Looking for Determinants of Ontological Security in the Spain of the Crisis

The concept of ontological security has a remarkable echo in the current sociology to describe emotional status of men of late modernity. However, the concept created by Giddens in the eighties has been little used in empirical research covering various sources of risk or uncertainty. In this paper, a scale for ontological security is proposed. To do this, we start from the results of a research focused on the relationship between risk, uncertainty and vulnerability in the context of the economic crisis in Spain. These results were produced through nine focus groups and a telephone survey with standardized questionnaire applied to a national sample of 2,408 individuals over 18 years. This work is divided into three main sections. In the fi rst, a scale has been built from the results of the application of different items present in the questionnaire used. The second part explores the relationships of the scale obtained with the variables further approximate the emotional dimensions of individuals. The third part observes the variables that contribute to changes in the scale: These variables show the structural feature of the ontological security.

Chemotherapy patient perception regarding communication with the healthcare staff

Purpose: To qualitatively explore the communication between healthcare professionals and oncology patients based on the perception of patients undergoing chemotherapy.Method: Qualitative and exploratory design. Participants were 14 adult patients undergoing chemotherapy at different stages of the disease. A socio-demographic and clinical data form was utilized along with semi-structured interviews. The interviews were audio-recorded, transcribed and content analysis was performed. Two independent judges evaluated the interview content in regards to emerging categories and obtained a Kappa index of 0.834.Results: Three categories emerged from the data: 1) Technical communication without emotional support, in which the information provided is composed of strictly technical information regarding the diagnosis, treatment and/or prognosis; 2) Technical communication, in which the information provided is oriented towards the technical aspects of the patient���s physical condition, while also providing psychological support for the patients��� subjective needs; and 3) Insufficient technical communication, win which there are gaps in the information provided causing confusion and suffering to the patient.Conclusions: Communication with emotional support contributes to greater satisfaction of chemotherapy patients. Practical implications: the results provide elements for the training of healthcare professionals regarding the importance of the emotional support that can be offered to cancer patients during their treatment.

Experiencias de danzaterapia de mujeres que han sufrido c��ncer de mama. Un estudio fenomenol��gico

Objective: This essay aims at identifying, describing and analyzing possible changes both in the experience of the body and in interpersonal relations of women with breast cancer, which result from their participation in Dance Therapy group meetings.Method: This is a phenomenologically oriented qualitative research using Maria Fux��s dance therapy method for group experiences. Eight meetings are described here, and an analysis of descriptions based primarily on Merleau-Ponty and Mar��a Fux is provided.Results: The participants have been able to express pain and sorrow over the circumstances that breast cancer and its relational environments have brought to their lives. They have been able to go through moments of creation and surrender to the rhythmic body sensations and experiential environment with different emotions lived separately and jointly. They have revived memories and sensations of their childhood and adolescence, and finally, they have rediscovered their sensitive body through body resignifications marked by the absence of the breast, and by means of feelings of greater acceptance and integration of lived experiences in new gestalts.Conclusions: This project is still under way, but it is already possible to conclude that the life experiences provided in dance therapy have allowed these women to improve their integration and welfare. Likewise, they have felt positive changes in the perception of their corporality and in their way of being in the world and with other subjects, thus experiencing the body in a new and different way.

Using blogs to enhance the capacity of mathematical communication in High School

The aim of this investigation is to analyze the use of the blog as an educational resource for the development of the mathematical communication in secondary education. With this aim, four aspects are analyzed: organization of mathematical thinking through communication; communication of mathematical thinking; analysis and evaluation of the strategies and mathematical thought of others; and expression of mathematical ideas using mathematical language. The research was conducted from a qualitative approach on an exploratory level, with the case study method of 4 classrooms of second grade of secondary education in a private school in Lima. The observational technique of 20 publications in the blog of the math class was applied; a study of a focal group with a sample of 9 students with different levels of academic performance; and an interview with the academic coordinator of the school was conducted. The results show that the organization of mathematical thinking through communication is carried out in the blog in a written, graphical and oral way through explanations, schemes and videos. Regarding communication of mathematical thinking, the blog is used to describe concepts, arguments and mathematical procedures with words and examples of the students. The analysis and evaluation of the strategies and mathematical thinking is performed through comments and debates about the publications. It was also noted that the blog does not facilitate the use of mathematical language to express mathematical ideas, since it does not allow direct writing of symbols nor graphic representation.

La prioridad del Igualitarismo Democr��tico

Este art��culo mostrar�� que las versiones estrictas del Igualitarismo Democr��tico y del Igualitarismo de la Suerte son implausibles ya que defienden una visi��n monista del objeto de la justicia igualitaria. Por el contrario, sus versiones moderadas son aceptables ya que admiten la composici��n plural del objeto de justicia igualitaria.Esta comprensi��n plural exige, sin embargo, el establecimiento de prioridades normativas ya que las exigencias de cada valor entran t��picamente en conflicto. Aqu��, se ofrecer��n tres argumentos para defender la prioridad del Igualitarismo Democr��tico sobre el Igualitarismo de la Suerte: uno instrumental, otro relacionado con el significado expresivo de las pol��ticas p��blicas estatales y un ��ltimo que justifica la divisi��n del trabajo moral igualitarista.

Anthroponyms in health care interventions

Anthroponyms in Health Care Interventions. This research aims to examine the personal names used by health care professionals to refer to and speak with patients in medical consultations. To this end, a large corpus was created with anthroponyms used in this type of settings and extracted from a variety of sources. The data obtained were then analyzed, classified, described and explained. Our hypothesis is that personal names are relevant elements in the relationship between the health care provider and the patient; however, their use is decidedly complex. In the following pages we will discuss this designative complexity by way of an introduction, an analysis of anthroponymic studies and a conclusion.

Communication and behavior in high reliability organizations: An Analysis of Communication in Civil Aviation

Communication can be seen as one of the most important features to manage conflicts and the stress of the work teams that operate in environments with strong pressure, complex operations and continuous risk, which are aspects that characterize a high reliability organization. This article aims to highlight the importance of communication in high-reliability organizations, having as object of study the accidents and incidents in civil aviation area. It refers to a qualitative research, outlined by documental analysis based on investigations conducted by the Federal Aviation Administration and the Center of Investigation and Prevention of Aeronautical Accidents. The results point out that human errors account for 60 to 80 percent of accidents and incidents. Most of these occurrences are attributed to miscommunication between the professionals involved with the air and ground operation, such as pilots, crewmembers and maintenance staff, and flight controllers. Inappropriate tone of voice usage, difficulties to understand different accents between the issuer and the receiver or even difficulty to perceive red flags between the lines of verbal and non-verbal communication, are elements that contribute to the fata of understanding between people involved in the operation. As a research limitation this present research pointed out a lack of a special category of "interpersonal communications failures" in the official agency reports. So, the researchers must take the conceptual definition of "social ability", communication implied, to classify behaviors and communication matters accordingly. Other research finding indicates that communication is superficially approached in the contents of air operations courses what could mitigate the lack of communications skills as a social ability. Part of the research findings refers to the contents of communication skills development into the program to train professional involved in air flight and ground operations. So, it is expected that this present article gives an appropriate highlight towards the improvement of flight operations training programs. Developing communication skills among work teams in high reliability organizations can contribute to mitigate stress, accidents and incidents in Civil Aviation Field. The original contribution of this article is the proposal of the main contents that should be developed in a Communication Skills Training Program, specially addressed to Civil Aviation operations.

���Digital Diagnostics and Communication (DDC) system��� Redesigning the Emergency Ambulance

During the development of a new treatment space for the UK emergency ambulance participatory observations with front-line clinicians revealed the need for an integrated patient monitoring, communication and navigation system. The research identified the different information touch-points and requirements through modes of use analysis, day-in-the-life study and simulation workshops with clinicians. Emergency scenario and role-play with paramedics identified 5 distinct ambulance modes of use. Information flow diagrams were created and checked by paramedics and digital User Interface (UI) wireframes were developed and evaluated by clinicians during clinical evaluations. Feedback from clinicians defined UI design specification further leading to a final design proposal. This research was a further development from the 2007 EPSRC funded ���Smart Pods��� project. The resulting interactive prototype was co-designed in collaboration with ambulance crews and provides a vision of what could be achieved by integrating well-proven IT technologies and protocols into a package relevant in the emergency medicine field. The system has been reviewed by over 40 ambulance crews and is part of a newly co-designed ambulance treatment space.
