Barriers to formal communication in the SANDF

This dissertation is an exploratory study aimed at empirically identifying and examining manifestations of communication barriers in the South African National Defence Force. A convergence model of communication is presented, describing the stages involved when individuals share the same information. The convergence model of communication delineates the relationship among the physical, psychological, and social aspects of communication. Two complementary theorems deduced by Kincaid (1988) from the convergence principle and the basic cybernetic process involved in information processing are applied in the analyses. The theorems specify the conditions under which intercultural communication will lead to convergence between members of different cultures involved. An empirically testable model was developed to collect information about possible communication barriers. The barriers are an indication of the restrictions on communication in the system and therefore indicate the possibility of restricting cultural convergence.CommunicationM.A. (Communication

Hobart Town Turkish Bath Co. Ltd. Index: Royal Society Collection

The establishment of a Turkish Bath Company for Hobart Town was promoted at a public meeting held on 25 October 1866. 200 shares off5 each were sold. The chairman of the Directors was Alfred Kennerley, later succeeded by Henry Llewellyn Roberts. The first secretary was W.G.Elliston. Land at the corner of Harrington and Collins Street ( south side) was purchased from Mr Adcock for l400 pounds in 1867 and adjacent land with two houses purchased from Moses Cohen in 1874. The building was designed by Henry Hunter and with fittings etc., cost about 1500 pounds. The baths were opened to the public in September 1868 (two days a week for ladies and 4 days for men). The company was wound up in 1892 and the premises sold. The buildings were finally pulled down in 1933. Royal Society RS.

Physiological responses of reared sea bream (Sparus aurata Linnaeus, 1758) to an Amyloodinium ocellatum outbreak

Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves that live within its ecological range. Fish mortalities are usually attributed to anoxia, associated with serious gill hyperplasia, inflammation, haemorrhage and necrosis in heavy infestations; or with osmoregulatory impairment and secondary microbial infections due to severe epithelial damage in mild infestation. However, physiological information about the host responses to A.ocellatum infestation is scarce. In this work, we analysed the proteome of gilthead sea bream (Sparus aurata) plasma and relate it with haematological and immunological indicators, in order to enlighten the different physiological responses when exposed to an A.ocellatum outbreak. Using 2D-DIGE, immunological and haematological analysis and in response to the A.ocellatum contamination we have identified several proteins associated with acute-phase response, inflammation, lipid transport, homoeostasis, and osmoregulation, wound healing, neoplasia and iron transport. Overall, this preliminary study revealed that amyloodiniosis affects some fish functional pathways as revealed by the changes in the plasma proteome of S. aurata, and that the innate immunological system is not activated in the presence of the parasite.DIVERSIAQUA, Portugal [MAR2020]Fundacao para a Ciencia e Tecnologia [SFRH/BD/118601/2016]info:eu-repo/semantics/publishedVersio

Subjects Agree to Participate in Environmental Health Studies without Fully Comprehending the Associated Risk

Recent advances in environmental health research have greatly improved our ability to measure and quantify how individuals are exposed. These advances, however, bring bioethical uncertainties and potential risks that individuals should be aware of before consenting to participate. This study assessed how well participants from two environmental health studies comprehended consent form material. After signing the consent form, participants were asked to complete a comprehension assessment tool. The tool measured whether participants could recognize or recall six elements of the consent form they had just reviewed. Additional data were collected to look for differences in comprehension by gender, age, race, and the time spent reading the original consent form. Seventy-three participants completed a comprehension assessment tool. Scores ranged from 1.91 to 6.00 (mean = 4.66); only three people had perfect comprehension scores. Among the least comprehended material were questions on study-related risks. Overall, 53% of participants were not aware of two or more study-related risks. As environmental public health studies pose uncertainties and potential risks, researchers need to do more to assess participants’ understanding before assuming that individuals have given their ‘informed’ consent

Implementing physically active learning: Future directions for research, policy, and practice

Objective Identify co-produced multi-stakeholder perspectives important for successful widespread physically active learning (PAL) adoption and implementation. Method A total of 35 stakeholders (policy makers, n = 9; commercial education sector, n = 8; teachers, n = 3; researchers, n = 15) attended a design thinking PAL workshop. Participants formed 5 multi-disciplinary groups with at least 1 representative from each stakeholder group. Each group, facilitated by a researcher, undertook 2 tasks: (1) using Post-it Notes, the following question was answered: within the school day, what are the opportunities for learning combined with movement? and (2) structured as a washing-line task, the following question was answered: how can we establish PAL as the norm? All discussions were audio-recorded and transcribed. Inductive analyses were conducted by 4 authors. After the analyses were complete, the main themes and subthemes were assigned to 4 predetermined categories: (1) PAL design and implementation, (2) priorities for practice, (3) priorities for policy, and (4) priorities for research. Results The following were the main themes for PAL implementation: opportunities for PAL within the school day, delivery environments, learning approaches, and the intensity of PAL. The main themes for the priorities for practice included teacher confidence and competence, resources to support delivery, and community of practice. The main themes for the policy for priorities included self-governance, the Office for Standards in Education, Children's Services and Skill, policy investment in initial teacher training, and curriculum reform. The main themes for the research priorities included establishing a strong evidence base, school-based PAL implementation, and a whole-systems approach. Conclusion The present study is the first to identify PAL implementation factors using a combined multi-stakeholder perspective. To achieve wider PAL adoption and implementation, future interventions should be evidence based and address implementation factors at the classroom level (e.g., approaches and delivery environments), school level (e.g., communities of practice), and policy level (e.g., initial teacher training)

Attitudes, understanding, and concerns regarding medical research amongst Egyptians: A qualitative pilot study

<p>Abstract</p> <p>Background</p> <p>Medical research must involve the participation of human subjects. Knowledge of patients' perspectives and concerns with their involvement in research would enhance recruitment efforts, improve the informed consent process, and enhance the overall trust between patients and investigators. Several studies have examined the views of patients from Western countries. There is limited empirical research involving the perspectives of individuals from developing countries. The purpose of this study is to examine the attitudes of Egyptian individuals toward medical research. Such information would help clarify the type and extent of concerns regarding research participation of individuals from cultural, economic, and political backgrounds that differ from those in developed countries.</p> <p>Methods</p> <p>We conducted semi-structured interviews with 15 Egyptian individuals recruited from the outpatient settings (public and private) at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. Thematic analysis followed.</p> <p>Results</p> <p>All individuals valued the importance of medical research; however most would not participate in research that involved more than minimal risk. Individuals were comfortable with studies involving surveys and blood sampling, but many viewed drug trials as being too risky. All participants valued the concept of informed consent, as they thought that their permission to be in a research study was paramount. Many participants had discomfort with or difficulty in the understanding several research concepts: randomization, double-blind, and clinical equipoise. Trust in the physicians performing research was important in deciding to participate in clinical research. The small sample size and the selection bias associated with obtaining information from only those who agreed to participate in a research study represent limitations in this study.</p> <p>Conclusion</p> <p>Overall, individuals in our sample recognize the value of medical research and have a great deal of trust regarding medical research and their participation in research. There were, however, concerns with the level of research risks associated with several types of medical research. Many also demonstrated confusion with certain research methodologies. We recommend 1) enhanced educational efforts regarding general research concepts to enhance the validity of informed consent and 2) further survey studies in other areas of Egypt to determine the generalizability of our results.</p

Cell activation-based screening of natively paired human T cell receptor repertoires

Adoptive immune therapies based on the transfer of antigen-specific T cells have been used successfully to treat various cancers and viral infections, but improved techniques are needed to identify optimally protective human T cell receptors (TCRs). Here we present a high-throughput approach to the identification of natively paired human TCRα and TCRβ (TCRα:β) genes encoding heterodimeric TCRs that recognize specific peptide antigens bound to major histocompatibility complex molecules (pMHCs). We first captured and cloned TCRα:β genes from individual cells, ensuring fidelity using a suppression PCR. We then screened TCRα:β libraries expressed in an immortalized cell line using peptide-pulsed antigen-presenting cells and sequenced activated clones to identify the cognate TCRs. Our results validated an experimental pipeline that allows large-scale repertoire datasets to be annotated with functional specificity information, facilitating the discovery of therapeutically relevant TCRs
