The body core temperature is a measure of the health and well-being of a person. This temperature seldom varies from the average of 37 °C (98.6 °F) and has been used to gage a person’s wellness at any time. The current work reviews the published health and medical works about this topic, focusing on the effects of hypothermia, especially with respect to neurological issues. The controversy still exists, and the jury is out. A heat transfer researcher’s insight foresees the possible results and calls for more research in the field. In addition, a perspective is provided for a couple of traditional “truths” about related topics that have been challenged in recent times.

Our aim was to analyse body core temperature and peripheral vascular microcirculation at skin hypothenar eminence of the hands and its relationship to symptoms in fibromyalgia syndrome (FMS). A total of 80 FMS women and 80 healthy women, matched on weight, were enrolled in this case–control study. Thermography and infrared thermometer were used for evaluating the hypothenar regions and core body temperature, respectively. The main outcome measures were pain pressure thresholds (PPTs) and clinical questionnaires. Significant associations were observed between overall impact [ β = 0.033; 95% confidence interval (95%CI) = 0.003, 0.062; p = 0.030], daytime dysfunction ( β = 0.203; 95%CI = 0.011, 0.395; p = 0.039) and reduced activity ( β = 0.045; 95%CI = 0.005, 0.085; p = 0.029) and core body temperature in FMS women. PPTs including greater trochanter dominant ( β = 0.254; 95%CI = 0.003, 0.504; p = 0.047), greater trochanter non-dominant ( β = 0.650; 95%CI = 0.141, 1.159; p = 0.013), as well as sleeping medication ( β = −0.242; 95%CI = −0.471, −0.013; p = 0.039) were also associated with hypothenar eminence temperature. Data highlighted that FMS women showed correlations among body core temperature and hand temperature with the clinical symptoms.

In recent years, outbreaks of highly contagious diseases, like the Ebola virus, have motivated vigorous efforts to screen travelers entering the United States, especially at airports. Screening involves monitoring the body temperature of entering travelers, and blocking entry of those showing a fever, indicating a potential infection. Typically, screening is performed using commercially available non-contact infrared thermometers (NCITs). These thermometers require specific use protocols (e.g., working distances) to provide accurate results, which may not be followed by inspectors reluctant to approach potentially contagious travelers. Furthermore, the NCITs’ accuracy is based on an assumption that the NCIT readings from a forehead will predict the body core temperatures using a simple common one-size-fits-all correction offset. Unfortunately, the temperature detected on the forehead surface by an NCIT may not represent the true body core temperature, due to the changing conditions of the external environment and/or surface conditions of the forehead skin. It is not clear whether the correction factor is able to adjust to the thermal environment, or whether the surface condition of the forehead, including sweat and skin tone, affects the NCIT readings. Before a clinical study is conducted to understand the differences between the forehead temperatures and the body core temperatures, a computational model to simulate temperature distribution inside and on the surface of the body is a cost-effective way to identify factors that influence the temperatures and to study the reasons for their deviations. The objectives of this study were to 1) develop a numerical whole-body model and perform computational heat transfer simulations of different body geometries and 2) perform parametric studies to evaluate the effect of environmental factors, such as air temperature and heat transfer coefficient, on the differences between the forehead temperature and body core temperature. This data can be used to evaluate correction factors or needed to use the measured forehead temperature to predict the body core temperature.

Abstract Advertising helps to establish a set of assumptions that the consumer will bring to all other aspects of their engagement with a given brand. Advertising provides tangible evidence of the financial credibility and competitive presence of an organization. Persuasion is becoming more important in advertising. In marketing, persuasive advertising acts to establish wants/motivations and beliefs/attitudes by helping to formulate a conception of the brand as being one which people like those in the target audience would or should prefer. Considering the changes in lifestyle and eating habits of a significant part of the population in urban areas in Romania, the paper aims to analyse how brands manage to differentiate themselves from competitors, to reposition themselves on the market and influence consumers, meeting their increasingly varied needs. Food brands on the Romanian market are trying, lately, to identify new methods of differentiation and new benefits for their buyers. Given that more and more consumers are becoming increasingly concerned about what they eat and the products’ health effects, brands struggle to highlight the fact that their products offer real benefits for the body. The advertisements have become more diversified and underline the positive effects, from the health and well - being point of view, that those foods offer (no additives and preservatives, use of natural ingredients, various vitamins and minerals or the fact that they are dietary). Advertising messages’ diversification is obvious on the Romanian market, in the context of an increasing concern of the population for the growing level of information of some major consumer segments.

Body-temperature elevations are multifactorial in origin and classified as hyperthermia as a rise in temperature due to alterations in the thermoregulation mechanism; the body loses the ability to control or regulate body temperature. In contrast, fever is a controlled state, since the body adjusts its stable temperature range to increase body temperature without losing the thermoregulation capacity. Fever refers to an acute phase response that confers a survival benefit on the body, raising core body temperature during infection or systemic inflammation processes to reduce the survival and proliferation of infectious pathogens by altering temperature, restriction of essential nutrients, and the activation of an immune reaction. However, once the infection resolves, the febrile response must be tightly regulated to avoid excessive tissue damage. During fever, neurological, endocrine, immunological, and metabolic changes occur that cause an increase in the stable temperature range, which allows the core body temperature to be considerably increased to stop the invasion of the offending agent and restrict the damage to the organism. There are different metabolic mechanisms of thermoregulation in the febrile response at the central and peripheral levels and cellular events. In response to cold or heat, the brain triggers thermoregulatory responses to coping with changes in body temperature, including autonomic effectors, such as thermogenesis, vasodilation, sweating, and behavioral mechanisms, that trigger flexible, goal-oriented actions, such as seeking heat or cold, nest building, and postural extension. Infrared thermography (IRT) has proven to be a reliable method for the early detection of pathologies affecting animal health and welfare that represent economic losses for farmers. However, the standardization of protocols for IRT use is still needed. Together with the complete understanding of the physiological and behavioral responses involved in the febrile process, it is possible to have timely solutions to serious problem situations. For this reason, the present review aims to analyze the new findings in pathophysiological mechanisms of the febrile process, the heat-loss mechanisms in an animal with fever, thermoregulation, the adverse effects of fever, and recent scientific findings related to different pathologies in farm animals through the use of IRT.

The COVID-19 pandemic has put a hold on the Silent Mentor Programme (SMP); this pause has not only caused unprecedented challenges for the delivery of medical education but has forced changes in the programme ceremony sessions. We aimed to describe the psychological impact and experiences of family members of silent mentors during the COVID-19 pandemic using qualitative interviews. Many expressed feelings of remorse and unrest about the unprecedented delay of the SMP. The delay increased negative emotions particularly among some elderly family members; however, there was no prominent negative effect on their functional health and well-being. Several participants relayed the belief that the soul cannot rest until the body receives a proper burial while some worried about the deterioration of the physical condition of the mentors. In conclusion, findings provide insights into the importance of not overlooking the mental health implications of delaying the SMP in future outbreaks or crises.

Orientation: Shame has been internationally researched in various cultural and societal contexts as well as across cultures in the workplace, schools and institutions of higher education. It is an emotional signal that refers to experienced incongruence of identity goals and the judgement of others.Research purpose: The purpose of this study was to focus on experiences of shame in the South African (SA) workplace, to provide emic, in-depth insights into the experiences of shame of employees.Motivation for the study: Shame in the workplace often occurs and might impact negatively on mental health and well-being, capability, freedom and human rights. This article aims at gaining some in-depth understanding of shame experiences in SA workplaces. Building on this understanding the aim is to develop awareness in Industrial and Organisational Psychologists (IOPs), employees and organisations to cope with shame constructively in addition to add to the apparent void in the body of knowledge on shame in SA workplaces.Research design, approach and method: An interpretative hermeneutical research paradigm, based on Dilthey’s modern hermeneutics was applied. Data were collected through semistructured interviews of 11 employees narrating their experiences from various workplaces, including the military, consulting organisations and higher education institutions. Content analysis was used for data analysis and interpretation.Main findings: The major themes around which shameful experiences evolved included loss of face, mistreatment by others, low work quality, exclusion, lifestyle and internalised shame on failure in the workplace. Shame is experienced as a disturbing emotion that impacts negatively on the self within the work context. It is also experienced as reducing mental health and well-being at work.Practical/managerial implications: SA organisations need to be more aware of shame in the workplace, to address the potential negative effects of shame on employees, particularly if they are not prepared to reframe shame into a constructively and positively used emotion. Safe spaces should be made available to talk about shame. Strategies should be applied to deal with shame constructively.Contribution/value-add: This article expands an in-depth understanding of shame from emic and culture-specific perspectives within SA workplaces. The findings are beneficial to IOPs and organisations to understand what shame is from the perspective of SA employees across cultural groups. The article thereby adds value to theory and practice, offering IOPs a deeper understanding of shame in the work context.

In cattle, core body temperature can be used as an important indicator of heat stress level. However, accurately recording core body temperature can be difficult and labor intensive. The objectives of the current study were 1) to compare the recorded tympanic and tail body temperature measurements in steers and 2) to determine the body temperature change of Angus and Brahman steers in a hot and humid environment. Data was analyzed using a repeated measure model where repeated measures were hourly tympanic and tail temperatures and their difference for individual steers during the day of the experiment. There was a significant breed effect (P=0.01), hour (P<0.0001) and breed by hour interaction (P<0.0001) for the tympanic temperature. Brahman steers, which are known to have superior thermotolerance, maintained a lower body temperature than the Angus steers during the afternoon under grazing conditions. In the Brahman steers there was only a minimal increase in the body temperature throughout the day, an evidence of the thermotolerance ability of the breed. In the Angus steers, which experienced an increase in their body temperature from hour to hour with a peak around 1600 hour; there was a significant difference between the tympanic and tail temperature during the times when the body temperature as measured by the tympanic recordings was the highest (1300 to 1700 hour). Our results indicate that the tympanic temperature can be used to accurately and continuously monitor core body temperature in a natural environment for up to several days and without disturbing the animal.

ResumoA dança é a arte de movimentar expressivamente o corpo seguindo movimentos ritmados, em geral ao som de música. Dessa forma, o significado da dança vai além da expressão artística, podendo ser vista como um meio para adquirir conhecimentos ou como opção de lazer. No campo de atuação do bacharelado, as investigações acadêmicas ainda são tímidas, urgindo de produções científicas que possam alimentar o campo científico sobre o tema. Dessa forma, o objetivo do estudo foi identificar e analisar as representações sociais que um grupo de bacharelandos do curso em Educação Física compartilha sobre a dança. A metodologia da pesquisa envolve uma abordagem qualitativa, tendo o estudo de campo como procedimento técnico. A amostra foi constituída por 200 indivíduos, sendo 85 homens e 115 mulheres com médias de idade entre 17 a 45 anos. A coleta de dados ocorreu através de questionário com associação livre de palavras, cujo termo indutor foi ”dança”. A análise foi feita por meio dos conteúdos das respostas. O resultado principal do estudo apontou que a maioria dos estudantes emprega sentido de dança como uma atividade técnica e a associam com saúde mental e bem-estar. Palavras-chave: Representação Social. Educação Física. Dança. AbstractDance is the art of expressively moving the body following rhythmic movements, usually to the sound of music. Thus, the meaning of dance goes beyond artistic expression, and can be seen as a means to acquire knowledge or as a leisure option. In the field of performance of the bachelor's degree, academic investigations are still timid, urging scientific productions that can feed the scientific field on the theme. Thus, the objective of the study was to identify and analyze the social representations that a group of Physical Education course bachelors shares about dance. The research methodology is a qualitative approach, with the field study as a technical procedure. The sample consisted of 200 individuals, 85 men and 115 women with a mean age between 17 and 45 years. Data collection was carried out through a questionnaire with free association of words, whose inducing term was, "dance". The analysis was done through the responses content. The main result of the study pointed out that most students use dance as a technical activity and associate it with mental health and well-being. Keywords: Social Representation. PE. Dance.

Hypothermia, described as a core body temperature of < 95%, is associated with ECG alteration abnormalities. Sinus bradycardia occurs when the body temperature drops below 90°F, and is correlated with gradual prolongation of the PR interval, QRS complex, QT interval. It can progress to ventricular and atrial fibrillation at a temperature reaching 89°F, which can lead to left ventricular dysfunction. Hypothermia is connected to the osborn waves, which at the end of the QRS complex consist of additional deflection. The inferior and lateral precordial leads are seen by Osborn waves, also known as J waves, Camel hump waves and hypothermic waves. As the body temperature decreases, it becomes more pronounced and a gradual expansion of the QRS complex raises the likelihood of ventricular fibrillation causing ventricle dysfunction.

The ArgumentPain has important biomedical socioanthropological, semiotic, and other facets. In this contribution pain and the experssion of pain are looked at from the perspective of evolutionary biology, utilizing, among others, cross-cultural data from field work in Melanesia.No other being cares for sick and suffering conspecifics in the way humans do. Notwithstanding aggression and neglect, common in all cultures, human societies can be characterized as empathic, comforting, and promoting the health and well-being of their members. One important stimulus triggering this caring response in others is the expression of pain. The nonverbal channel of communication, particularly certain universal — i.e., culture-independent facial expressions, gestures, and body postures, convey much of the message from the painstricken person to the group.These behaviors signal the person's physical and psychical pain, sadness, grief, and despair in ways very similar to the signs given by infants and small children: the body loses tonus and sinks or drops to the ground, the gestures are those of helplessness. Pain and grief may be so strong that control is lost not only over the body's posture but also over the mind's awareness. In such cases the afflicted person may carry out actions endangering himself or others. In general, these behavior patterns resemble those of infants in situations of distress and danger, and it is not surprising that the response of the members of the group is basically parental: taking care, assisting and consoling.Perceptive and behavioral patterns which developed in the course of avian and mammalian phylogeny to serve the well-being of the young have proven, as was shown by Eibl-Eibesfeldt (1989), to be powerful building blocks for actions in other spheres of human interaction. Love is one such field, the reactions to a conspecific suffering pain is another.
