    Workplace mobbing is a hostile and unethical communication, systematically aimed from one or more individuals towards mostly one individual, who are forced into a helpless position and are held in it by constant bullying. This article describes some of the most important characteristics of mobbing: offensive behaviour, organizational and non-organizational causes of this behaviour, the victim and the consequences. Modern business environment is complex, dynamic, volatile, and requires better ability to adjust. Constant changes are a part of organizational reality, but they also produce an ideal environment for all kinds of conflicts. Conflicts are inevitable in every organization, but the task of its management is to identify them and resolve before they affect the workforce, productivity and costs. The idea is to avert psychological abuse and aberrant behaviour such as mobbing which that may cause physical and mental disorders. Mobbing is a problem of the modern society; as a violation of human rights it is relatively new and unrecognised in Croatia. Abuse is mostly psychological: it affects the victim's health and life, quality of work, productivity, profitability, and may lead to significant economic losses in the community. Mobbing can be averted by joint forces that would involve employee and management, medical and legal professionals, and even community as a whole. The more an organization pursues excellence based on trust and business ethics, the higher the probability that mobbing will be averted or stopped.

    Workers with handicap or psychological impairment are frequently submitted to mobbing. If causative factors of psychological disorders are not recognized, the physician charged of medical surveillance of workers may himself become a prosecutor and enhance the mobbing actions to the extent that the mobbed worker is discharged. In order to avoid this undue effect, the physician should strictly adhere to the body of legislation and to good occupational medicine practices. Health surveillance for occupationally exposed groups of workers is required under specific health and safety legislation. Workers unexposed to hazard in the workplace cannot be included in health surveillance programme, and declaring these workers unfit for their job is a patent violation of Workers' Statute Law. Psychological disorders should be carefully evaluated in order to clarify their relationship with work. The case of a worker affected with schizophrenia, already reported in the literature, is here re-analysed in order to emphasize these concepts.

    Full Text Available Workplace mobbing has become a common topic. Taking into account the increasing reports of this act, this study was aimed at investigating the prevalence of mobbing in relation to university students who work and also ascertaining the most frequent biosociodemographic and work characteristics of the group of workers who were mobbed. The sample was composed of 457 working students living in the metropolitan area of Porto Alegre, in the state of Rio Grande do Sul, and usedas instruments a Biosociodemographic and Employment questionnaire and the Negative Acts Questionnaire (NAQ. It could be observed that 89.3% of the students had a mobbing score according to the NAQ – objective measure. As per the subjective measure, 11.2% of the participants stated to having beenmobbed. High rates of the practice of hostile acts in the workplace can be noted, but these are often viewed as mundane and normal acts in the workplace. In conclusion, it is necessary to seek alternatives in order to overcome this problem, which already affects a significant number of workers.

    Full Text Available RQ: Is there a connection among perception of hostile and unethical communication, timely removal of causes and employee satisfaction?Purpose: Perceived mobbing in the organization, analysing causes and timely removal of them without any effect; achieve an environment of satisfied employees. The purpose is to study the relationship amongthe categories: perceiving mobbing, removing the effects, employee satisfaction.Methods: Qualitative research approach, method of interview by using the seven steps principles.Results: The findings clearly state that being aware of the negative factors and psychological abuse in organizations was present. The interview participants perceived different negative behaviours especially by the female population and from the side of superiors. In some organizations perceived negative factors are insults,insinuations, low wages, inadequate working day, competition, lobbying, and verbal threats. All negative factors lead to serious implications for employees, in which the organization can lose its reputation, productivity is reduced, costs of employment can increase with more sick leaves and in extreme cases, the results can be soserious that the organization can end in bankruptcy or liquidation.Organization: The result of the study warns management to acceptcertain actions and remediate the situation in organizations. The employer and managers must do everything to protect their subordinates from violence and potential offenders.Society: The research study warns on the seriousness of mobbing among employees, the aim is to bring the issue to individuals and society. The victim usually needs help (health costs, losses in the pension system, increased unemployment, and lower productivity of the whole society.Originality: In view of the sensitivity of the issues, the author concludes that the existing research studies are based especially on closed questions (questionnaires; however, interviews create mutual trust between

    Full Text Available Our reality, having been subject to the numerous social crises during the last decades of the 20th century, is characterized by frequent incidences of powerlessness and alienation. The man is more frequently a subject to loneliness and overcomes the feeling of worthlessness, no matter whether he considers himself an individual or a part of a whole larger social. Such an environment leads to development of aggression in all fields of ones life. This paper has as an objective the pointing out of the mental harassment that is manifested in the working environment. There is a prevalence of mobbing cases, as a mode of pathological communication. The result of this is that a person, subjected to this kind of abuse, is soon faced with social isolation. This research also aspires to initiate the need for social groups self-organization of which victims are part of. The reaction modality of a social group directly conditions the outcome of the deliberate social drama, one is subjected to it as a result of mobbing.

  10. Barking and mobbing.

    Lord, Kathryn; Feinstein, Mark; Coppinger, Raymond

    2009-07-01

    Barking is most often associated with the domestic dog Canis familiaris, but it is a common mammalian and avian vocalization. Like any vocalization, the acoustic character of the bark is likely to be a product of adaptation as well as an expression of the signaler's internal motivational state. While most authors recognize that the bark is a distinct signal type, no consistent description of its acoustic definition or function is apparent. The bark exhibits considerable variability in its acoustic form and occurs in a wide range of behavioral contexts, particularly in dogs. This has led some authors to suggest that dog barking might be a form of referential signaling, or an adaptation for heightened capability to communicate with humans. In this paper we propose a general 'canonical' acoustic description of the bark. Surveying relevant literature on dogs, wild canids, other mammals and birds, we explore an alternative functional hypothesis, first suggested by [Morton, E.S., 1977. On the occurrence and significance of motivation-structural rules in some bird and mammal sounds. Am. Nat. 111, 855-869] and consistent with his motivational-structural rules theory: that barking in many animals, including the domestic dog, is associated with mobbing behavior and the motivational states that accompany mobbing.

    Full Text Available The currently specific problem at work is chronic fatigue, a syndrome characterized by physiological and emotional exhaustion and often generated (through permanent frustration by the position with a too much or too low volume of work. First of all, the treatment of stress, of burnout or in countering resilience, is preventive and consists in gaining a better resistance. In simpler words, fighting against those phenomena is maintaining personal health. “Health is a fully favorable condition, physically, mentally and socially, and not merely the absence of disease or infirmity”[1]. Later it was added that health is the “capacity to lead a socially and economically productive life.” But, when the general concern is to destroy the balance, whatever that may mean – the balance of the active body or the body “ready to leave the system”, balance of knowledge, individual and collective mental equilibrium, functional balance of economy, balance of the bio-system… - we must not remain indifferent. It occurs frequently a phenomenon which is a relatively unknown concept for the Romanian economy – the mobbing or bullying.

    In recent years, psychological problems that are caused by working conditions, like burn out syndrome, are more commonly observed. In our study, we aimed to evaluate mobbing exposure, factors causing mobbing and precautions for mobbing in residency students who are educated in anaesthesiology and reanimation clinics in Turkey. After obtaining consent from the ethics committee, we sent our questionnaires to the secretariats of the departments by postal mail. Completed questionnaires were collected in our department's secretariat blindly and randomly mixed. One hundred and one participants were returned the questionnaires. Data was statistically analysed in SPSS 21.0 software programme. During residency programme, sated to have experienced mobbing one or more time. Interestingly, 5.9% participants complained of physical mobbing. Mobbing exposure was more common in females. The most serious new onset psychosomatic symptoms stated during residency were committing suicide (2%), addiction (16%), severe depression (18%), panic attack (8%), more accidents (7%) and tendency of violence (15%). In mobbing group there was statistically significant dissatisfaction rate. In professions where mobbing is common, incidences of psychiatric diseases and suicide attempts are high are increased. Who are under risk for experiencing mobbing should be noticed carefully to ensure good judgement and problems should be inspected objectively in a detailed manner. Anesthesiology societies and other medical professional societies should establish mobbing committees. Thus, mobbing problems can be resolved and healthy career oppurtunities can be presented to residents.

    The phenomenon of the physical, moral or psychical violence in the working environment, variously indicated as "mobbing", "workplace bullying" or "workplace harassment", is to date object of numerous studies, mostly of epidemiological type, which are yet to clear, in a sufficient way, the aspects of that phenomenon, the possible causes, risk factors, constituent characteristics and consequences. Our search, a systematic review of the existing studies in literature and a meta-analysis of the jobs chosen to such scope, has shown that only a small percentage of the researches conducted on the topic is represented from studies that collected original information on the subject. The results of the meta-analysis show that in the category of the mobbed workers the psychosomatic disturbs, stress, and anxiety are greater than in the group of controls and that the perception of the surrounding environment is more negative in the victims of mobbing compared with the not mobbed workers. The value of such results is reduced by the characteristics and the heterogeneity of the studies.

  18. Function of snake mobbing in spectral tarsiers.

    Gursky, Sharon

    2006-04-01

    Numerous species are known for their tendency to approach and confront their predators as a group. This behavior is known as mobbing. Snakes seem to be one of the more consistent recipients of this type of predator-directed behavior. This paper explores individual differences (sex and age) in the mobbing behavior of the spectral tarsier toward live and model snakes. This study was conducted at Tangkoko Nature Reserve (Sulawesi, Indonesia) during 2003-2004. During this research, 11 natural mobbing events and 31 artificially induced mobbing events were observed. The mean number of individuals at a mobbing was 5.7. The duration of mobbing events was strongly correlated with the number of assembled mobbers. Adults were more likely than other age classes to participate in mobbings. Males were more likely than females to participate in mobbings. Mobbing groups often contained more than one adult male, despite the fact that no spectral tarsier group contains more than one adult male. No difference in body size between extragroup males and resident males was observed, refuting the "attract the mightier" hypothesis. The number of mobbers did not affect whether the tarsier or the snake retreated first, countering the "move-on" hypothesis. The "perception advertisement" hypothesis was tentatively supported, in that live snakes were rarely seen in the area following mobbing calls, in comparison to when tarsiers either ignored the snake or alarm call.

    The term 'mobbing' is defined as antagonistic behaviors with unethical communication directed systematically at one individual by one or more individuals in the workplace. This cross-sectional and descriptive study was conducted for the purpose of determining the mobbing behaviors encountered by nursing school teaching staff in Turkey, its effect on them, and their responses to them. A large percentage (91%) of the nursing school employees who participated in this study reported that they had encountered mobbing behaviors in the institution where they work and 17% that they had been directly exposed to mobbing in the workplace. The academic staff who had been exposed to mobbing behaviors experienced various physiological, emotional and social reactions. They frequently 'worked harder and [were] more organized and worked very carefully to avoid criticism' to escape from mobbing. In addition, 9% of the participants stated that they 'thought about suicide occasionally'.

    The aims of this study were to develop a mobbing scale for academic nurses and to determine their mobbing experiences. Data were collected between January and June 2006 with a 60-item mobbing scale and a questionnaire composed of 6 questions concerning demographics and 10 questions regarding nurses' opinions about mobbing. For the Mobbing Scale for Academic Nurses, the content validity index was 88%, item-to-total correlations ranged from .41 to .73, Cronbach alpha was .97, and Kaiser-Meyer-Olkin measure of sampling adequacy was .72. Barlett's test yielded quite significant results (chi2= 7905.47, p = .000). The scale was composed of eight subscales. One fifth of the academic nurses experienced mobbing, and there was evidence of mobbing at university nursing schools. The mobbing scale for academic nurses can be used to collect reliable and accurate data about mobbing experienced by academic nurses. If there is mobbing in nursing faculties and schools, appropriate precautions should be taken to protect people against mobbing, and a safe and comfortable atmosphere must be created in nursing faculties and schools.

    Abstract Understanding the factors that facilitate the emergence of cooperation among organisms is central to the study of social evolution. Spotted hyenas Crocuta crocuta frequently cooperate to mob lions Panthera leo, approaching the lions as a tightknit group while vocalizing loudly in an attempt to overwhelm them and drive them away. Whereas cooperative mobbing behavior has been well documented in birds and some mammals, to our knowledge it has never been described during interactions between 2 apex predators. Using a 27-year dataset, we characterize lion–hyena encounters, assess rates of mobbing behavior observed during these interactions, and inquire whether mobbing results in successful acquisition of food. Lions and hyenas interacted most often at fresh kills, especially as prey size and the number of hyenas present increased. Possession of food at the beginning of an interaction positively affected retention of that food by each predator species. The presence of male lions increased the probability of an interspecific interaction but decreased the likelihood of hyenas obtaining or retaining possession of the food. Hyena mobbing rates were highest at fresh kills, but lower when adult male lions were present. The occurrence of mobbing was predicted by an increase in the number of hyenas present. Whether or not mobbing resulted in acquisition of food from lions was predicted by an increase in the number of mobs formed by the hyenas present, suggesting that cooperation among hyenas enhances their fitness.

    2010-03-01

    We present experimental and theoretical studies of one type of mobbing behavior in which swarms of prey animals (e.g., tree swallows) harass a predator (e.g., a red-tailed hawk). Empirical field data were collected for tree swallows mobbing a fixed model predator; previous studies have established that this experimental design provokes the same response as actual ``perch-and-wait'' predator behavior. We extended these earlier studies using stereometric video to record the three-dimensional trajectories of prey birds and mobbing cries; we also analyzed single-angle video data taken of crows mobbing red-tailed hawks in flight. Video recordings of red-tailed hawk flight were filmed and analyzed to establish the dynamics of potential predator attacks. The trajectory analysis employed particle-tracking methods and statistical analyses to understand and model the dynamical rules governing this behavior. Swarming behavior during mobbing exhibited a high degree of periodicity and coordination both for fixed predator and in-flight mobbing attacks. The trajectories of individual mobbing birds were analyzed as a random walk superimposed on an approximately elliptical flightpath. Computer simulation studies reproduce several aspects of this behavior, in particular explaining how the mobbing strategy employed by prey birds minimizes the risk of hawk predation while optimizing the frequency of harassing attacks.

    Full Text Available Academic mobbing is a non-violent, sophisticated, ‘ganging up’ behaviour adopted by academicians to “wear and tear” a colleague down emotionally through unjustified accusation, humiliation, general harassment and emotional abuse. These are directed at the target under a veil of lies and justifications so that they are “hidden” to others and difficult to prove. Bullies use mobbing activities to hide their own weaknesses and incompetence. Targets selected are often intelligent, innovative high achievers, with good integrity and principles. Mobbing activities appear trivial and innocuous on its own but the frequency and pattern of their occurrence over long period of time indicates an aggressive manipulation to “eliminate” the target. Mobbing activities typically progress through five stereotypical phases that begins with an unsolved minor conflict between two workers and ultimately escalates into a senseless mobbing whereby the target is stigmatized and victimized to justify the behaviours of the bullies. The result is always physical, mental, social distress or illness and, most often, expulsion of target from the workplace. Organizations are subjected to great financial loss, loss of key workers and a tarnished public image and reputation. Public awareness, education, effective counselling, establishment of anti-bullying policies and legislations at all levels are necessary to curb academic mobbing. General practitioners (GPs play an important role in supporting patients subjected to mental and physical health injury caused by workplace bullying and mobbing.

    Full Text Available An increasing number of organizations face the problem of mobbing, which represents a serious, widespread problem with numerous consequences for victims, organizations, and society. We also recognize the connection this phenomenon has with the emergence of post-traumatic stress disorder (PTSD. PTSD poses one of the most critical consequences for victims of mobbing, who mostly consist of employees at lower organizational levels. Our research focuses on the prevalence of mobbing in Slovenia, its correlation to PTSD, and some differences in the subjective and objective assessments of being exposed to mobbing. We found that the prevalence of mobbing in Slovenia can be compared to some previous assessments as well as data from other countries. Among the study's participants, 24% could be classified as regular victims of mobbing. For the first time, we link mobbing with PTSD using a Slovenian sample. We also recorded some interesting differences between subjective and objective assessments of mobbing, thereby indicating the importance of subjective conceptualizations of mobbing acts, which should be investigated in greater detail in future research.

    This is a descriptive and comparative study of levels of mobbing perception among nurses, causes and perpetrators of mobbing, reactions to and factors affecting mobbing. Data for the study were collected from a sample of 180 Turkish nurses between July 2007 and January 2008 using a three-part questionnaire. Nurses were frequently subjected to mobbing. Younger nurses, nurses with less institutional and professional experience, nurses with lower levels of education, and nurses working in internal medicine clinics and night shifts reported higher levels of mobbing. Nurses reported their managers as the most frequent perpetrators of mobbing, and bad working conditions as the most important cause of mobbing. Many participants reported that they had come to accept mobbing incidents and did not lodge any complaints prior to the study. However, they claimed that they will not tolerate mobbing any longer, and will lodge verbal and written complaints. © 2012 The Authors.

    Full Text Available Mobbing and harassment are widely analysed in organizations providing various services but are little studied in the companies undertaking industrial activities. Therefore, the aim of the paper is to diagnose the prevalence of mobbing and harassment in the steel enterprises. The case study analysis of the largest steel producer in the world, and specifically its division in Poland was used to determine the prevalence of these phenomena. It was found out that the said company is the example of the ethically and socially responsible organization. However, the interviews indicate that single cases of mobbing and harassment activities (though relatively rare were also observed. They were distributed among three groups of employees: 1 those who do physical work (are directly engaged in the production process; 2 employees involved in the administrative activity and sales; and 3 managerial staff.

    This book presents mathematical models of mob control with threshold (conformity) collective decision-making of the agents. Based on the results of analysis of the interconnection between the micro- and macromodels of active network structures, it considers the static (deterministic, stochastic and game-theoretic) and dynamic (discrete- and continuous-time) models of mob control, and highlights models of informational confrontation. Many of the results are applicable not only to mob control problems, but also to control problems arising in social groups, online social networks, etc. Aimed at researchers and practitioners, it is also a valuable resource for undergraduate and postgraduate students as well as doctoral candidates specializing in the field of collective behavior modeling.

    The aim of this study was to study suicide risk in subjects exposed to mobbing, that is, systematic psychological harassment in the workplace. Such psychological harassment, unique to the workplace, threatens both the emotional well-being and professional ability of its victims. The items of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) that assess suicide risk were studied in 102 individuals who were exposed to mobbing. The results indicated that individuals exposed to mobbing had clear differences on the MMPI-2 from normative samples. In addition, those who appeared to be at risk for suicide differed in their scores from those not at risk. Implications for psychopathology and suicide preventions are discussed.

    Mobbing in the language of ethologists means a particular behaviour of a group of animals consisting of several members forming an alliance against a single animal, in order to eliminate this animal away from the group. This term has been adopted in current usage to mean a kind of relationship at the workplace that, by aggressive and underhand means, aims at influencing or expelling the person. The term "bossing" is used to indicate a negative action, under the meaning described above, made by one or more senior persons, or possibly by the employer. In the Italian Parliament, under the current legislature, several bills are pending regarding this problem. Besides the aspects of topical interest in the problem, there are first and foremost the different kinds of reaction-adaptation to mobbing, according to the type of individual internal working models in action, that can be anxious/avoiding, anxious/resistant or disorganised. The purpose of our study was a clinical evaluation of the different ways of adaptation-reaction to a mobbing-type relationship at the workplace, and of the type of internal working models found among the examined patients. A clinical interview was carried out with 40 patients who, over a period of 12 months of observation, came to request a clinical assessment, for medical-legal reasons, of their psycho-pathological state and ways to react to adverse situations at the workplace, such as a mobbing or bossing. Besides the psychological and relational effects of mobbing, the reactions of the examined subjects to mobbing are also described, considering also the different cognitive self-organization possibilities, according to the individual internal working model, regarding patterns of attachment in adult age. The most frequent internal working model seems to be the one related to resistant attachment, followed by the avoidance and lastly--rarely--the disorganized model. Furthermore we observed among these subjects a certain deficit in meta

    Full Text Available ABSTRACT Mobbing is an occupational health problem at alarming levels in all cultures and professions worldwide regardless of sex, age, experience, education and hierarchy. Mobbing is a dynamic process, varying from simple to complex. Mobbing, causing psychological, physiological and social traumas on employee’s health that are hard to recover, is mostly seen in public and health sectors and individuals aged 30-40 years. It is known that more than 50% of health care professionals are to be mobbing victims. Nurses are frequently mobbing victims, because they are at risk as they work in health care sector and are women. However, researches revealing reflections of mobbing experienced by nurses on care of sick or healthy individuals are not available. Researches revealing reflections of mobbing experienced by nurses on care of sick or healthy individuals and quality of care are required to evaluate the actual cost of mobbing. Yet, mobbing is legally accepted as guilt, the fight against mobbing is getting more important. During the fight against mobbing experienced by nurses, both individually and institutionally, a systematical approach is needed. [TAF Prev Med Bull 2013; 12(2.000: 183-192

    The aim of the study is to develop and validate a questionnaire able to evaluate the risk of mobbing at the workplace. A multiple-choice questionnaire has been developed which contains, among the different items, only one revealing a mobbing situation. The questionnaire has been administered to two groups (group A--243 subjects in a mobbing situation and group B--63 subjects without exposure to mobbing) and the differences in the scores obtained have been analysed. The questionnaire has proved to be valid and reliable. The results show that the presence of five mobbing actions is sufficient to define the workplace situation as potentially at risk for mobbing. The study reveals some limits in the selection of the two samples thus needing some adjustment. However, the questionnaire, also in the present form, can be considered a tool able to detect the mobbing situations.

    To determine the type, frequency and cause of the most frequent hostile behaviors in a sample of nurses in the Balearic Islands and the socio-professional variables involved. We performed a cross-sectional descriptive study. The sample was composed of 464 members of the association of nurses of the Balearic Islands (392 women and 49 men). Age ranged from 25 to 65 years (mean: 35.11; SD: 9.62); 368 worked in public institutions and 71 in private centers. The instrument used was the Psychological Mobbing Questionnaire. A total of 17.2% of the nurses believed they had experienced mobbing at work (men: 22.4%; women: 14.5%). Significant differences were found according to age, but not according to institution. The most frequent hostile behavior was related to distortion of information, criticism of the purported victim, and lack of professional consideration. The perpetrators of mobbing were mainly, and very significantly, the bosses. According to these results, one in five nurses in the Balearic Islands has experienced mobbing in the workplace. However, because of the low response rate, caution should be exercised when generalizing these results. Nevertheless, health institutions should bear these findings in mind to ensure standards of behavior that do not jeopardize workers' health and dignity.

    Bollani, A

    2008-01-01

    The author analyzes the juridical profile that the phenomenon of mobbing assumes within the Italian legal system, emphasizing that the English term of current usage does not designate any specific legal entity as such but simply refers, in summary fashion, to deeds and behaviours that need to be qualified according to the law in vigour. The normative frame of reference for mobbing is found in article 2087 of the Civil code, which states, as an open, teleologically oriented norm, the employer's obligation to safeguard the moral person of the employee; hence the onus is on the interpreter, essentially, to evaluate if there has been, in actual fact, a contravention of this safeguarded legal right. The author then discusses profiles that intersect with mobbing (or behaviours perceived as such) drawing on other cases regulated by the law such as the safeguarding of professionality (art. 2103 of the Civil code), and underlines that often mobbing ends by being construed as a mere accompaniment to, if not duplication of, other typical cases. Finally, the author discusses aspects of the judicial process related to the allegation and proof of the facts constituting the offence, and to the damage, in its various non patrimonial components.

    The aim of the study was to determine whether the nurses have been exposed to mobbing or not, and to reveal the causes of the mobbing between 3 November 2008 and 31 December 2008. This research was a mixed method study involving survey and focus group interviews. The sample was calculated using sample calculation formula, and 206 nurses were included in the survey study. Four focus group interviews were later carried out with 16 nurses. The survey method and semi-structured question form were used to collect data. The percentage and chi-square were used to evaluate the quantitative data, and for the analysis of the qualitative data, descriptive analyses were made through direct quotations from the nurses' statements. According to the mobbing scale, 9.7% of the nurses had been exposed to mobbing, but according to their own declarations, 33% had been exposed. Some of the nurses (25.2%) who expressed that they had been exposed to mobbing reported that the executor of mobbing was the head nurse and 9.2% said that the reason for mobbing was 'communication problems'. Nurses under 25 years of age and those who work in intensive care units are apparently exposed to mobbing more frequently than others (Pmobbing behaviours should be determined and they should be educated about leadership. Nurses should be educated about assertiveness to prevent mobbing. The necessary measures should be adopted to solve the 'communication problems', which are shown as a major reason for mobbing.

    Mobbing represents nowadays a major challenge for Occupational Medicine. We examined, during the last seven years, 253 patients who asked medical assistance for psychopathological problems by them ascribed to mobbing in the working environment. All patients underwent occupational health visit, psychological counselling (including personality tests administration), and psychiatric evaluation. A clinical picture probably due to mobbing was diagnosed in 37 workers: 2 cases of Post-Traumatic Stress Disorder (PTSD), 33 of Adjustment Disorder (AD), and 2 of anxiety disorder. Regarding mobbing typology, we found 19 cases of vertical mobbing (by an employer/manager to employees), 14 cases of strategic mobbing, 3 cases of horizontal mobbing (among colleagues), and one non intentional mobbing. In conclusion, a pure mobbing syndrome was diagnosed in a lower proportion than that reported by other investigators. The described interdisciplinary approach appears useful for the diagnostic assessment of suspect mobbing cases, that in turn is crucial for prognosis and treatment, as well as in relation to medico-legal issues and work-related compensation claims.

    Unrelated passerine birds often join together while mobbing, a widespread antipredator behavior during which birds harass a predator. Although previous analyses concluded that mobbing could not have evolved via reciprocity, Krams and colleagues' field experiments show that birds preferentially join mobs with neighbors that have aided them previously, suggesting that these birds utilize reciprocity-based strategies involving individual recognition and recollection of previous interactions with others. This implies a level of sophistication in bird communities greater than had previously been realized.

It was found that there is a strong impact of organizational culture dimensions on mobbing, and that mobbing affects job satisfaction, organizational commitment and organizational citizenship behaviour. Results concerning organizational commitment show that this variable is not a mere effect of mobbing in general, but rather that it is also a direct impact of culture on this outcome.

    Full Text Available This article focuses on exemplifying the features of discrimination phenomenon in the workplace, a phenomenon that has appeared in the Romanian social studies only in the last 4 years. Mobbing phenomenon has been analyzed by several countries in Europe such as England, France, Germany; after these analyzes it has been found that this phenomenon refers only to actions of intense psychological pressure. Actions are geared to a single employee, in order to cause it to leave its job. Without these measures, dismissal of the employee would lead to numerous legal problems on the employer. In conclusion, employee who is the subject of mobbing phenomenon must endure a long period of time a series of injustices focused on himself, but also extremely high humiliation, which determines him to mentally give up and take the decision to resign.

For this purpose, we collected data from a sample of 396 workers (61 men and 331 women) belonging to this sector in the Region of Murcia (Spain). A questionnaire with the following measurement instruments was administered: a Spanish adaptation of the revised Negative Acts Questionnaire (Sáez, García, & Llor, 2003), the Psychosomatic Problems Questionnaire (Hock, 1988), and a measure of absenteeism. The results revealed a significant and positive relation between workplace mobbing and psychosomatic symptoms, but not with absenteeism. The implications of the results for future research are discussed.

    The paper addresses the issue of violence among correctional officers. The aim of the study was to assess the frequency of exposure to violence in this professional group. The study comprised the sample of 222 correctional officers who voluntary and anonymously fulfilled the MDM questionnaire. The MDM Questionnaire allows for assessing exposure to aggression and mobbing at work. Preliminary assessment of exposure to single aggressive acts and mobbing shows a quite alarming tendency--around one third of subjects under the study experienced repetitive aggressive acts from coworkers and/or superiors. The problem of organizational aggression in correctional institutions should be recognized in details to develop effective preventive measures against violent behaviors occurring at work.

    2013-01-01

    Full Text Available This paper considers the consequences of mobbing in order to indicate possibilities for their measurement. Mobbing can be measured through its effects as the mental, physical and social consequences of mobbing are visible and can be quantified. The effect of mobbing can be expressed by the difference in the health of the victim of mobbing before and after exposure to the stressful mobbing activities. This can be compared through laboratory and specialist analysis of auto anamnestic data, accessible through the employee’s cumulative health record that is kept with the occupational health institution or with the employee’s chosen physician. It is expected the consequences of mobbing will correlate with the length and intensity of exposure, as well as with the personal “equation” of the victim and the circumstances of the surroundings. Using medical records, an expert could provide a statement on the degree of intangible damage made to the employee who has suffered harassment at work. The intensity of exposure to mobbing and the degree of pain caused can be measured by assessment scales. A major drawback of these instruments lies in their strong dependence on culture.

    Full Text Available Mobbing, a rising issue in the occupational health area, has recently been paid attention more and more in the academic and business settings. Mobbing is a series of action having multidimensional features socially and psychologically, and it is frequent in occupational environment. Mobbing may present itself as behaviors, words, acts, gestures, or writings that affect personality, dignity, physical, and psychological integrity. Early 1990’s were the time studies about mobbing started to be done, indicating its negative effects on both individual and the working place. These extend from stress and depression to psychosomatic disorders, and even chronicle diseases and cardiovascular problems. Workplace mobbing is repetitive, unreasonable malicious behavior directed toward an employee or a group of employees, that creates risk to health and safety. It may manifest as intimidation, physical violence, discrimination, threats, social isolation, and destabilization. The most prominent result is lack of continuity. Organizational problems, time pressure, lack of leadership and task definition etc. are defined to be potential risk factors. For prevention, there must be an organized intervention including a strategically approach towards mobbing and a positive environment at workplace. There is a need for standardization, and studies to define and evaluate mobbing behavior in order to make a comparison between different cultures and occupations. In this review article mobbing was examined with the view of public health. [TAF Prev Med Bull 2009; 8(6.000: 515-520

    Increasingly, mental health and medical professionals have been asked to assess claims of psychological harm arising from harassment at the workplace, or "mobbing." This study assessed the personality and psychopathological profiles of 146 individuals exposed to mobbing using validity, clinical, and content scales of the Minnesota Multiphasic Personality Inventory 2. Profiles and factor analyses were obtained. Two major dimensions emerged among those exposed to mobbing: (a) depressed mood, difficulty in making decisions, change-related anguish, and passive-aggressive traits (b) somatic symptoms, and need for attention and affection. This cross-sectional pilot study provides evidence that personality profiles of mobbing victims and psychological damage resulting from mobbing may be evaluated using standardized assessments, though a longitudinal study is needed to delineate cause-and-effect relationships.

    Mobbing and burnout in human resources management are important topics in labor psychology. It is important to research the levels of mobbing and burnout of human resources in the health sector, primarily in doctors. Although there have been some studies on the mobbing and burnout of doctors, there has been a limited number of studies on the relationship between mobbing and burnout in the health sector. This study aims to examine the relationship between mobbing and burnout (emotional exhaustion, depersonalization, personal accomplishment) levels of resident doctors at a public university research and training hospital in Turkey and to investigate whether mobbing and burnout levels vary significantly according to gender, marital status, medical branch and age. This study was conducted on resident doctors at the Ondokuz Mayıs University Research and Training Hospital between 01.04.2009 and 30.06.2009. Legal permission for the study was received from the Rector's Office of Ondokuz Mayıs University. The Maslach Burnout Inventory for measuring burnout levels in doctors and the Leymann Inventory of Psychological Terror for measuring doctors' mobbing levels were the research instruments employed. Sampling was not used in this study. The aim was to administer the research instruments to all the residents (the universe of this study consisted of 510 assistant doctors). 52.94 % of residents responded to all of the questions in these instruments. In the data analysis, a t-test, ANOVA, regression analysis and descriptive statistics were used. At the end of the analyses, it was found that the mean mobbing level of residents is 1.97; the mean emotional exhaustion level of residents is 2.97; the mean level of depersonalization is 2.95; and the mean level of personal accomplishment is 2.94. Mobbing and burnout levels of residents vary significantly in terms of medical branch. This study indicated that there are relationships between mobbing, emotional exhaustion

    Psychological violence in the workplaces is increasing and the Italian national health service and trade unions are mostly involved in single cases of diagnosis strategy. To analyse published mobbing cases using a mobbing prevention approach that takes account of the main civil rights violation in mobbing actions. 25 cases were analysed in order to identify the type of mobbing, gender, the professional position and the main civil rights that were violated. Seven main civil rights had been violated in the 25 mobbing cases: health, work, professional skills, equal treatment, legality, diversity, dignity. Men working in unhealthy conditions, mostly due to unhealthy working environments, were forced to leave under the pressure of moral violence. In women, equal treatment and diversity were the main rights that were violated. Co-worker support was absent in all cases. A civil rights assessment to prevent mobbing is considered. Italian legislation, particularly the Civil Code, can be the legislation key for prevention, with the employer responsible for providing a violence-free environment as indicated in European Directive 626/94.

    Mobbing and burnout can cause serious consequences, especially for health workers and managers. Level of burnout and exposure to mobbing may trigger each other. There is a need to conduct additional and specific studies on the topic to develop some strategies. The purpose of this study is to determine the relationship between level of burnout and exposure to mobbing of the managers (head physician, assistant head physician, head nurse, assistant head nurse, administrator, assistant administrator) at the Ministry of Health hospitals. The "Leymann Inventory of Psychological Terrorization" scale was used to measure the level of exposure to mobbing and the "Maslach Burnout Inventory" scale was used to measure the level of burnout of hospital managers. The relationship between level of burnout and exposure to mobbing was analyzed by Pearson's Correlation Analysis. Participants and research context: The population of this study included managers (454 managers) at the Ministry of Health hospitals in the metropolitan area of Ankara between September 2010 and May 2011. All the managers were tried to conduct, but some managers did not want to reply to the questionnaire and some managers were not found at their workplace. Consequently, using a convenience sampling, 54% of the managers replied to the questionnaire (244 managers). Ethical consideration: The approval of the study was granted by the Ministry of Health in Turkey. Furthermore, the study was evaluated and accepted by the Education, Planning and Coordination Council of one of the education and research hospitals in the study. Positive relationships were found among each subdimension of the mobbing and emotional exhaustion and depersonalization. A negative relationship was found between each subdimension of the mobbing and personal accomplishment. In hospitals, by detecting mobbing actions, burnout may be prevented. Exposure to mobbing and burnout could be a serious problem for head nurses who are responsible for both

    Full Text Available The aim of this study is to research into the mobbing behaviour perceived by teacher counsellors in terms of variables. Descriptive research method has been used in this study. The universe of this study has included the teacher counsellors working at Gaziantep. As it is desired to be reached the whole of the universe in the study, the way of sampling is not preferred. 219 teachers working on seven different districts of Gaziantep have comprised the sample group of this study. With the purpose of providing the description of the personal information of the people included in the study, ‘Occupational Satisfaction Scale’ has been used, and with the purpose of evaluating the perceived mobbing behaviour ‘Mobbing Detection Scale’ which includes 35 items has been used. Data collection tools were delivered to the schools with a directive and they were retaken in closed envelopes. The obtained data was analyzed with SPSS program. With the aim of determining whether occupational satisfaction and personal variables predicts the perceived mobbing, regression analysis has been used in the study. The variables of marital status, educational level, occupational seniority and school types have been found to be a meaningful predictor of mobbing behaviour perceived by teacher counsellors. Suggestions have been developed in line with the obtained data. Key

    Mobbing is characterized by the repetition, over a long period of time, of hostile behavior and unethical conduct carried out by a hierarchical superior or co-worker, against someone's physic and mental integrity, endangering one's job or disturbing the work environment. This current investigative study intends to assess the existence, frequency, and intensity of mobbing within the Portuguese nurse population, as well as its impact on their well-being and interpersonal relationships. The study carried out was quantitative, correlational, and cross-sectional. A questionnaire was used as the form to collect data. The questionnaire was sent out to 11 institutions in Portugal which were chosen at random, and it was also made available on a website for whoever wished to respond. The sample was composed of 3,227 nurses from various health institutions in Portugal. From the results obtained it was observed that on average each nurse undergoes 11 aggression conducts in their main place of work. The types of aggression suffered with greater intensity by the victims are communication blockage and being discredited at work. The predominant types of mobbing are the horizontal and the descending type. Nurses suspected the following motivations for those who had perpetrated mobbing against them: envy or jealous, not yielding or having been influenced by blackmail, not being subservient and being innovative, or entrepreneurial in the new work methods or perspectives. Almost half of the victims claim to have had health problems as a result of having suffered mobbing in their workplace.

    Aim To determine the extent of Turkish junior male physicians’ exposure to mobbing behavior and its correlation with physicians' characteristics. Methods The study included physicians recruited for compulsory military service in April 2009. No sampling method was used, questionnaires were delivered to all physicians, and 278 of 292 (95%) questionnaires were returned. We used Leymann Inventory of Psychological Terror including 45 items for data collection and structural equation model for data analysis. Results A total of 87.7% of physicians experienced mobbing behavior. Physicians who worked more than 40 hours a week, single physicians, physicians working in university hospitals and private hospitals, and physicians who did not have occupational commitment were more exposed to mobbing (P Mobbing was not associated with specialty status, service period, age, and personality variables (P > 0.05). All goodness-of- fit indices of the model were acceptable (χ2 = 1.449, normed fit index = 0.955, Tucker Lewis index = 0.980, comparative fit index = 0.985, and root mean square error of approximation = 0.040). Conclusions Workplace mobbing is a critical problem for junior male physicians in Turkey. We suggest an introduction of a reporting system and education activities for physicians in high-risk groups.

    Heinz Leymann defined this phenomenon as a hostile and unethical communication. In his definition Leymann points out that the distinction between "conflict" and "mobbing" does not focus on what is done or how it is done, but rather on the frequency and duration of whatever is done. The exposure to the strain of mobbing begins to result in psychiatrically or psychosomatically pathological conditions due to the accumulation of negative emotions. Leyman emphasizes four main factors which cause harrasment in the workplace: lack of clarity of goals in work, inadequate management, victim's social status and low moral standards in the work environment. The epidemiological data in the European Union, indicate great national differences relative to the percentage of those subjected to mobbing, with increasing exposure rates in all professions, the highest being found in education (14%) and health services. Nurses are considered a professional group at a rather high risk for trauma caused by harrasment in the workplace. "Horizontal violence" is a widely used term regarding mobbing aclions in nursing profession even though vertical violence is present both in this profession and all other health services. Horizontal violence is implied due to the traditional assumption that nurses have a subordinate role compared to doctors, which often brings them into conflict with their peers. Mobbing may be prevented by systematic primary prevention, information, education, and training in communication skills. As a result, we could expect to get a higher quality of nursing care and healthier nurses.

    Reciprocity is fundamental to cooperative behaviour and has been verified in theoretical models. However, there is still limited experimental evidence for reciprocity in non-primate species. Our results more decisively clarify that reciprocity with a tit-for-tat enforcement strategy can occur among breeding pied flycatchers Ficedula hypoleuca separate from considerations of byproduct mutualism. Breeding pairs living in close proximity (20–24 m) did exhibit byproduct mutualism and always assisted in mobbing regardless of their neighbours' prior actions. However, breeding pairs with distant neighbours (69–84 m) either assisted or refused to assist in mobbing a predatory owl based on whether or not the distant pair had previously helped them in their own nest defense against the predator. Clearly, these birds are aware of their specific spatial security context, remember their neighbours' prior behaviour, and choose a situation-specific strategic course of action, which could promote their longer-term security, a capacity previously thought unique to primates.

We are faced with it in the situation when an employee is often and in a longer period of time undergoing harassment, rough time and is treated worse than other employees and experiences a feeling of isolation. The effects of such treatment depend upon the exposure period and individual features of mobbed people and its range is broad and contains biological, psychological,, social and financial aspects. The aim of this work is to draw attention to mobbing problem and the need of systematic surveys In this field. Such surveys may help to increase social awareness and also introduce new solutions in its prevention and overcoming

    Mobbing is a widespread anti-predator strategy in birds, and predators are generally expected to avoid mobbing. For example, observational studies suggest that the cryptic roosting behaviour of nocturnal predators, such as many owls, may be a strategy to limit mobbing. In this paper, we present...... the results of the first experimental study investigating to what degree roost exposure influences the risk of being mobbed, and the intensity of a mobbing incidence once initiated. To determine these factors, we used an experimental setup with taxidermic mounts of tawny owls Strix aluco in Grib Skov forest......, Denmark. The risk of an owl being mobbed during a 50 min morning survey period increased with the exposure of its roosting position, from 24% when hidden to 85% when openly exposed. The corresponding increase in the afternoon was from 6% to 36%. This suggests that an owl may minimize the mobbing rate...

    Nowadays, there are many reasons for people to be stressful and restless in their working environments. One of the reasons leading to this situation is known as "mobbing". The term "mobbing" means "bullying of an individual by a group". It usually happens among employees. The main effects of mobbing are the generation of stress and reduction of employee performance at work. In general, research shows that mobbing is particularly common in the public sector. The aim of this research is to understand the frequency of mobbing on employees in the Turkish maritime industry as a case study. In this study, a questionnaire survey on ship, shipyard, public and private company workers was applied to understand how often employees are exposed to mobbing. After analysing the results, it is also aimed to obtain information about the reasons and causes of mobbing, and then we can get some advice for this issue.

    Plasmid typing can provide insights into the epidemiology and transmission of plasmid-mediated antibiotic resistance. The principal plasmid typing schemes are replicon typing and MOB typing, which utilize variation in replication loci and relaxase proteins respectively. Previous studies investigating the proportion of plasmids assigned a type by these schemes ('typeability') have yielded conflicting results; moreover, thousands of plasmid sequences have been added to NCBI in recent years, without consistent annotation to indicate which sequences represent complete plasmids. Here, a curated dataset of complete Enterobacteriaceae plasmids from NCBI was compiled, and used to assess the typeability and concordance of in silico replicon and MOB typing schemes. Concordance was assessed at hierarchical replicon type resolutions, from replicon family-level to plasmid multilocus sequence type (pMLST)-level, where available. We found that 85% and 65% of the curated plasmids could be replicon and MOB typed, respectively. Overall, plasmid size and the number of resistance genes were significant independent predictors of replicon and MOB typing success. We found some degree of non-concordance between replicon families and MOB types, which was only partly resolved when partitioning plasmids into finer-resolution groups (replicon and pMLST types). In some cases, non-concordance was attributed to ambiguous boundaries between MOBP and MOBQ types; in other cases, backbone mosaicism was considered a more plausible explanation. β-lactamase resistance genes tended not to show fidelity to a particular plasmid type, though some previously reported associations were supported. Overall, replicon and MOB typing schemes are likely to continue playing an important role in plasmid analysis, but their performance is constrained by the diverse and dynamic nature of plasmid genomes.

    2016-01-01

    Japanese great tits ( Parus minor ) use a sophisticated system of anti-predator communication when defending their offspring: they produce different mobbing calls for different nest predators (snake versus non-snake predators) and thereby convey this information to conspecifics (i.e. functionally referential call system). The present playback experiments revealed that these calls also serve to coordinate multi-species mobbing at nests; snake-specific mobbing calls attracted heterospecific individuals close to the sound source and elicited snake-searching behaviour, whereas non-snake mobbing calls attracted these birds at a distance. This study demonstrates for the first time that referential mobbing calls trigger different formations of multi-species mobbing parties.

    The term "mobbing" has today erroneously come to be a huge general recepticle for all the conflicts and interpersonal problems breaking out in the work environment. The author, who collaborates as clinical psychologist in an anti-mobbing network, shows that frequently events at work and personality structures are closely connected. In particular, attention to the modes of coping becomes a fundamental aspect for the diagnosis of mobbing. If psychic distress has gradually moved from a neurotic basis to a more preponderantly narcissistic pathology, the author underlines that precisely narcissistic pathologies may be correlated to the vast container of mobbing.

    2008-01-01

    Previous research has documented that a variety of anxiety, depressive, and psychosomatic symptoms are present in a substantial portion of mobbing victims. This study aimed to explore the frequency of posttraumatic stress disorder (PTSD) among mobbing victims, and to investigate how PTSD was linked to pertinent psychometric scales. We recruited 20 mobbing victims and conducted the Structural Clinical Interview (SCID) to assess PTSD according to DSM-IV criteria. The trauma criterion was homogeneously defined as mobbing. 55% of our entire sample had a current PTSD, and 70% suffered from severe posttraumatic stress symptoms according to the Impact of Event Scale. Using multivariate analysis of variance (MANOVA), we found that mobbing victims with a current PTSD tended to demonstrate higher levels of stress and depressive symptoms, and less quality of life (SF 36 Short-Form Health Survey), especially in terms of bodily pain, compared with those without a PTSD diagnosis. No significant differences in personality factors (Freiburg Personality Inventory) between mobbing-victims with and without PTSD were evident by multivariate analysis. Univariate statistics, however, revealed that mobbing-related PTSD showed a trend towards higher scores in social orientation and somatic complaints. There was no general evidence that mobbing victims with a PTSD used more often negative and positive coping strategies (SVF - Stress Coping Questionnaire). However, they showed a tendency to employ control strategies, avoidance, social withdrawal, and cognitive preoccupation. Posttraumatic stress disorder subsequent to mobbing can occur frequently. PTSD therefore should be specifically considered in routine care.

    Victims of workplace mobbing show diverse coping behavior. We investigated the impact of this behavior on bystander cognitions, emotions, and helping toward the victim, integrating coping literature with attribution theory. Adult part-time university students (N = 161) working at various organizations participated in a study with a 3(Coping: approach/avoidance/neutral) × 2(Gender Victim: male/female) × 2(Gender Bystander: male/female) design. Victims showing approach (vs. avoidance) coping were considered to be more self-reliant and less responsible for the continuation of the mobbing, and they elicited less anger. Continuation responsibility and self-reliance mediated the relationship between the victim's coping behavior and bystanders' helping intentions. Female (vs. male) participants reported more sympathy for the victim and greater willingness to help, and female (vs. male) victims elicited less anger. Theoretical and practical implications of the findings are discussed.

    Full Text Available As the phenomenon of abuse in the workplace came to a closer public eye of a broader audience through media coverage, there is not a more fertile ground for a fully detailed problem explanation and search for its short or long-term solution. The dose of seriousness concerning the issue of mobbing isn’t only given for its negative effect on a business organization, but also for the mutation of a society’s culture, as well. The research paper outlines the mobbing phenomenon by presenting the theoretical and practical (statistical diagnosis through which, for a better understanding of the situation, there are added testimonies of mobbing victims, as well as legal and extra-judicial solutions for the issue. The observation of the phenomena is focused on the research and data presentation, using examples from Serbia and Europe. Putting aside the obvious differences in approach, a great space for implementation of European developed countries’ principles can be seen. The same principles could be introduced on the domestic scene, with the introduction of mandatory work conditions that are considered decent.

  17. Mobbing vocalizations as a coping response in the common marmoset.

    Science.gov (United States)

    Cross, N; Rogers, L J

    2006-02-01

    Using a non-invasive method of sampling saliva followed by assay for cortisol levels, we found that common marmosets (Callithrix jacchus) show a decrease in cortisol levels after seeing a snake-model stimulus that reliably elicits mobbing (tsik) calls. In fact, there was a significant positive correlation between the number of tsik vocalizations made and the magnitude of the decrease in the cortisol concentrations. Furthermore, marmosets with higher levels of cortisol prior to being exposed to the stimulus produce more tsik calls than those with lower levels of cortisol. Subsequent experiments showed that, in response to 15 min of isolation with no visual or auditory contact with conspecifics (a traditional stressor), cortisol levels increased significantly. However, playback of the mobbing calls of a familiar conspecific to individual isolated marmosets not only prevented the rise in cortisol, but also actually caused a decrease in the levels of this hormone. This suggests that the mobbing calls serve to calm the marmoset after experiencing a stressful situation. This finding results in a greater understanding as to the role of physiological responses during communication in this species and could have implications for the welfare of marmosets in captivity.

    Full Text Available In the article the problem of psychological violence (mobbing in organizations, his psychological characteristics in emigration. Analyzes the types of mobbing, its negative influence on the personality, negative consequences which not only affect physical and psychological health, but also lead to physical diseases, and suicide. The author emphasizes that in conditions of exile (in Israel psychological violence is experienced more acutely and is characterized by a prolonged depressed state. One important reason for this situation is the decline of the former social status of the emigrant, being able to quickly inclusion in the new society, loss of important social ties, the need to adopt different social norms, sometimes contradicting previously established views. Against the background of such negative phenomena in humans appear aggression, desire to dominate at any cost to regain lost status. The problem of mobbing in the modern world is very important and requires a robust approach at the state level. That psychological safety is a condition for ensuring the formation and development of functional comfort, maintaining a high level of personal emotional security and social-psychological skills, optimization of reserve possibilities of the person in activities.

    This research was conducted as a descriptive and cross-sectional study with the purpose of determining the mobbing experienced by nurses who work in healthcare facilities in Turkey, its emotional, social and physiological effects on the nurses and the actions that the individuals take to escape from the mobbing. The term 'mobbing', which includes workplace terrorizing, pressure, frightening, belittling and psycho-terror, is defined as the presence of systematic, directed, unethical communication and antagonistic behaviour by one or more individuals. These actions that occur frequently and continue for a long time are the most serious and effective causes of workplace stress. The person who is the target of the mobbing is left without help, without protection and alone in the workplace. Individuals who are exposed to psychological abuse experience physiological, psychological and social problems that are related to high levels of stress and anxiety. The research participants were 505 nurses of whom 325 (64%) worked in public and 180 (36%) in private hospitals. All of the participants were female. A questionnaire developed by the researchers in the light of information in the literature was used for data collection and had four sections including the participants' demographic characteristics and questions asking about mobbing behaviours, reaction to mobbing incidents and actions taken to escape from the mobbing. The data were collected between October and December 2005 by giving an envelope to the participants and then collecting the responses in the closed envelope. The overwhelming majority (86.5%) of the nurses participating in the research reported facing mobbing behaviour in the workplace in the last 12 months. The nurses working at private hospitals faced statistically significantly more mobbing behaviours than those at public hospitals (pworkplace need to be defined and appropriate policies and procedures need to be developed and shared with all employees to

    About a decade the background of the both public and scientific increasing interest in the topic "mobbing". But unfortunately the term "mobbing" is often applied in dubious and inflationary way as synonym for each professional disagreement. The reason for this may among others be that until today no internationally acknowledged standard definition on mobbing exists. According to the in German operational and judicial practice contemporarily most frequent and favourite paraphrases mobbing includes: intended chicanery/hostility (systematics) towards a person (purpose, asymmetry of power) in certain frequency/continuity (at least once a week for six months) with the intention to ostracize a person from his/her employment. In the European states prevalence varies between 2% and 15%, in Germany a national report supports with representative data about 3%, here women are more affected than man. The highest prevalence rates are found in services sector and in public health, social services and education. Aetiology places mobbing mainly as a multi-factor process with complex reciprocity between individual and professional/social factors conditioned in many cases by unresolved conflicts or occupational changes. In first place mobbing is no medical diagnosis, but health injuries resulting from mobbing makes this phenomenon more and more important for social and professional medicine. In view of diagnostic safeguarding with respect to differential diagnostic clarification of a mobbing case good interdisciplinary cooperation of both internal and external protagonists is recommended. Mobbing interventions include individual (for instance social support) as well as operational measures (for instance role of top executives, calling in of a mediation committee). Prevention against occupational mobbing must given high attention. An essential part is regarded the introduction of occupational conventions against mobbing.

  15. Novel mobbing strategies of a fish population against a sessile annelid predator.

    Lachat, Jose; Haag-Wackernagel, Daniel

    2016-09-12

    When searching for food, foraging fishes expose themselves to hidden predators. The strategies that maximize the survival of foraging fishes are not well understood. Here, we describe a novel type of mobbing behaviour displayed by foraging Scolopsis affinis. The fish direct sharp water jets towards the hidden sessile annelid predator Eunice aphroditois (Bobbit worm). We recognized two different behavioural roles for mobbers (i.e., initiator and subsequent participants). The first individual to exhibit behaviour indicating the discovery of the Bobbit directed, absolutely and per time unit, more water jets than the subsequent individuals that joined the mobbing. We found evidence that the mobbing impacted the behaviour of the Bobbit, e.g., by inducing retraction. S. affinis individuals either mob alone or form mobbing groups. We speculate that this behaviour may provide social benefits for its conspecifics by securing foraging territories for S. affinis. Our results reveal a sophisticated and complex behavioural strategy to protect against a hidden predator.

  16. Stress and nurses' horizontal mobbing: moderating effects of group identity and group support.

    Topa, Gabriela; Moriano, Juan A

    2013-01-01

    Horizontal mobbing is a process of systematic and repeated aggression towards a worker by coworkers. Among others, stress has been pointed out as one of the antecedents that favors the onset of horizontal mobbing, whereas group support to the target could act as a buffer. Moreover, the social identity approach emphasizes that group identity is an antecedent of group support. This study explores the interaction of group support and group identity in the explanation of horizontal mobbing in a sample (N = 388) of registered nurses and licensed practical nurses employed at two large hospitals in Madrid and Navarre (Spain). The results show that stress is positively associated to horizontal mobbing, whereas group support and group identity were negative predictors of horizontal mobbing. Furthermore, the combination of low group identity and low group support precipitated HM among nurses. Copyright © 2013 Elsevier Inc. All rights reserved.

    Recently results find that victims of mobbing place themselves apart because of their personality types. This study deals with the question whether a difference between victims of mobbing and those non victims can be determined as far as depression, fear and personality type is concerned. Anonymous questionnaires including anxiety-, depression- and personalityscales were sent to 1 000 insured whose application for medical rehabilitation had been granted. 25% of the applicants felt they had been mobbed. 60% of the victims suffered from psychic disorders. The values for depression and anxiety and the mark in the personality scale were significantly high. Mobbing is a relatively common problem for patients in rehabilitation which has to be taken seriously. Although it can not be resolved which direction has to be taken by judging cause and effect. It should be checked if there is enough support during medical rehabilitation for the victims of mobbing. Georg Thieme Verlag KG Stuttgart-New York.

  18. Local predation pressure predicts the strength of mobbing responses in tropical birds

    Directory of Open Access Journals (Sweden)

    Luis SANDOVAL, David R. WILSON

    2012-10-01

    Full Text Available Many birds join cooperative mobbing aggregations and collectively harass predators. Individuals participating in these ephemeral associations benefit by deterring the predator, but also incur energetic costs and increased risk of predation. Explaining the evolution of mobbing is challenging because individuals could prevail by selfishly seeking safety while allowing others to mob. An important step in understanding the evolution of mobbing is to identify factors affecting its expression. The ecological constraints model suggests that animals are more likely to cooperate under adverse environmental conditions, such as when local predation pressure is high. We tested this prediction by comparing the mobbing responses of several species of birds to the local abundance of their primary predator, the ferruginous pygmy-owl Glaucidium brasilianum. We used acoustic playback to elicit mobbing responses in environments where owls were common, uncommon, or rare. Stimuli were either the song of a ferruginous pygmy-owl or the mobbing calls of three of the owl’s common prey species. During each playback, we characterized mobbing responses by noting the number of species and individuals that approached the loudspeaker, as well as the closest approach by any bird. Mobbing responses to both stimuli were strong in locations where Ferruginous Pygmy-owls were common, intermediate where owls were uncommon, and weak where they were rare. This pattern persisted even after controlling for differences in species richness and composition among the three environments. Results support the ecological constraints model and provide strong evidence that intense predation pressure increases the expression of cooperative mobbing in tropical birds [Current Zoology 58 (5: 781-790, 2012].

    Mps-one-binder (Mob) proteins play a crucial role in yeast cytokinesis. After cloning two Mob1-like genes, MsMob1-A and MsMob1-B from alfalfa (Medicago sativa L.) we show that, although they are constitutively expressed in roots, stems, leaves, flowers and pods, their transcripts and proteins are mostly produced in actively proliferating tissues. A polyclonal antibody specifically raised against MsMob1 proteins was used for immunolocalization studies in synchronized root tip cells. The subcellular localization of MsMob1-like proteins is demonstrated to be cell cycle-regulated. Cytoplasmic localization is faint and diffused during G 1 and S. It becomes concentrated in punctuate and fibrillar structures in G 2 as well as M phase. At the stage of cytokinesis, the protein is found at the emerging cell plate marking the progressive formation of the septum. Mob1 proteins partially co-localize with microtubules structures functionally related to the spindles and important for cytokinesis in eukaryotic cells. The MsMob1 expression cannot rescue the lethality of the yeast mob1 mutant, suggesting that interaction of Mob1 proteins with their effectors may be species-specific. Localization of Mob1 proteins in the inner layer of the root cap indicates an additional function for this class of proteins in plants, which is likely related to the onset of programmed cell death

    This research was designed to determine the impact of assertiveness training on the mobbing experience of nurses. This study was conducted in two phases. In the first phase, 218 nurses completed the mobbing scale; the education group consisted of 38 nurses who received a score at or above 204 points. A total of 180 nurses were excluded from the education group because they received less than 204 points. The study was conducted with 30 nurses because 8 nurses did not agree to participate in the study. The 30 nurses received the assertiveness training program. Six months after training, the nurses completed the mobbing scale and Rathus Assertiveness Inventory (RAI) again. The assertiveness training positively affected the assertiveness and mobbing scores (p = .000). After the training, the assertiveness scores increased and the mobbing condition score decreased (p Assertiveness training is an effective method for decreasing mobbing. In line with these results, training programs, which support nurses' personal development by providing counseling and support to nurse victims of mobbing, are recommended. © 2015 The Author(s).

    Degenerate Primer MOB Typing is a PCR-based protocol for the classification of γ-proteobacterial transmissible plasmids in five phylogenetic relaxase MOB families. It was applied to a multiresistant E. coli collection, previously characterized by PCR-based replicon-typing, in order to compare both methods. Plasmids from 32 clinical isolates of multiresistant E. coli (19 extended spectrum beta-lactamase producers and 13 non producers) and their transconjugants were analyzed. A total of 95 relaxases were detected, at least one per isolate, underscoring the high potential of these strains for antibiotic-resistance transmission. MOBP12 and MOBF12 plasmids were the most abundant. Most MOB subfamilies detected were present in both subsets of the collection, indicating a shared mobilome among multiresistant E. coli. The plasmid profile obtained by both methods was compared, which provided useful data upon which decisions related to the implementation of detection methods in the clinic could be based. The phylogenetic depth at which replicon and MOB-typing classify plasmids is different. While replicon-typing aims at plasmid replication regions with non-degenerate primers, MOB-typing classifies plasmids into relaxase subfamilies using degenerate primers. As a result, MOB-typing provides a deeper phylogenetic depth than replicon-typing and new plasmid groups are uncovered. Significantly, MOB typing identified 17 plasmids and an integrative and conjugative element, which were not detected by replicon-typing. Four of these backbones were different from previously reported elements. Copyright © 2014 Elsevier Inc. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Nicola Vitulo

    2007-01-01

    Full Text Available The MOB family includes a group of cell cycle-associated proteins highly conserved throughout eukaryotes, whose founding members are implicated in mitotic exit and co-ordination of cell cycle progression with cell polarity and morphogenesis. Here we report the characterization and evolution of the MOB domain-containing proteins as inferred from the 43 eukaryotic genomes so far sequenced. We show that genes for Mob-like proteins are present in at least 41 of these genomes, confi rming the universal distribution of this protein family and suggesting its prominent biological function. The phylogenetic analysis reveals fi ve distinct MOB domain classes, showing a progressive expansion of this family from unicellular to multicellular organisms, reaching the highest number in mammals. Plant Mob genes appear to have evolved from a single ancestor, most likely after the loss of one or more genes during the early stage of Viridiplantae evolutionary history. Three of the Mob classes are widespread among most of the analyzed organisms. The possible biological and molecular function of Mob proteins and their role in conserved signaling pathways related to cell proliferation, cell death and cell polarity are also presented and critically discussed.

    To assess the frequency of reported mobbing and the association among mobbing, working environment factors, stress, health outcome, personality type, and work ability index in a sample of physicians in Bosnia and Herzegovina. We conducted a questionnaire survey using a validated self-reported questionnaire among 511 physicians in national health sector of Bosnia and Herzegovina. The questions covered five major categories of mobbing behavior. Characteristics of the work, perceived work environment and its effects, stress, health, and satisfaction with work and life were assessed by the standardized abridged form of Occupational Stress Questionnaire (OSQ). A standardized questionnaire Work Ability Index (WAI) was used to determine the relation between mobbing and work ability. Of 511 surveyed physicians, 387 (76%) physicians self-reported mobbing behavior in the working environment and 136 (26%) was exposed to persistent mobbing. More than a half of the physicians experienced threats to their professional status and almost a half felt isolated. Logistic regression analysis showed that lack of motivation, loss of self-esteem, loss of confidence, fatigue, and depressiveness were significantly associated with lack of support from colleagues. Intention to leave work was associated with lack of support from colleagues (OR 2.3, 95% CI, 1.065-3.535; t =4.296, P =0.003) and lack of support from superiors (OR 1.526, 95% CI, 0.976-2.076; t =5.753; P =0.001). Isolation or exclusion and threats to professional status were predictors for mental health symptoms. Persistent mobbing experience was a significant predictor for sick leave. Exposure to persistent threat to professional status and isolation or exclusion as forms of mobbing are associated with mental health disturbances and lack of self-esteem and confidence. Setting up a system of support for physicians exposed to mobbing may have important benefits.

  7. Social-bond strength influences vocally mediated recruitment to mobbing.

    2016-11-01

    Strong social bonds form between individuals in many group-living species, and these relationships can have important fitness benefits. When responding to vocalizations produced by groupmates, receivers are expected to adjust their behaviour depending on the nature of the bond they share with the signaller. Here we investigate whether the strength of the signaller-receiver social bond affects response to calls that attract others to help mob a predator. Using field-based playback experiments on a habituated population of wild dwarf mongooses (Helogale parvula), we first demonstrate that a particular vocalization given on detecting predatory snakes does act as a recruitment call; receivers were more likely to look, approach and engage in mobbing behaviour than in response to control close calls. We then show that individuals respond more strongly to these recruitment calls if they are from groupmates with whom they are more strongly bonded (those with whom they preferentially groom and forage). Our study, therefore, provides novel evidence about the anti-predator benefits of close bonds within social groups. © 2016 The Author(s).

    Social relations in the workplace are one of the main sources of risk for the onset of mobbing. In this work, we analyzed, through the perceived social climate, the influence of interpersonal relations on the characterization of the processes of mobbing, in a sample of local police (N = 235). In particular, the policemen and women's opinions of the quality of the personal relations among the group members and the treatment they receive from the command posts were assessed. The results of the study show that the development of guidelines of social interaction based on discrimination and abuse of authority are predicting variables of mobbing in this group.

  12. Flocking and self-defense: experiments and simulations of avian mobbing

    We have performed motion capture studies in the field of avian mobbing, in which flocks of prey birds harass predatory birds. Our empirical studies cover both field observations of mobbing occurring in mid-air, where both predator and prey are in flight, and an experimental system using actual prey birds and simulated predator ``perch and wait'' strategies. To model our results and establish the effectiveness of mobbing flight paths at minimizing risk of capture while optimizing predator harassment, we have performed computer simulations using the actual measured trajectories of mobbing prey birds combined with model predator trajectories. To accurately simulate predator motion, we also measured raptor acceleration and flight dynamics, well as prey-pursuit strategies. These experiments and theoretical studies were all performed with undergraduate research assistants in a liberal arts college setting. This work illustrates how biological physics provides undergraduate research projects well-suited to the abilities of physics majors with interdisciplinary science interests and diverse backgrounds.

    Today the most important problem in the work place is psychological abuse, which may affect the health because of high levels of stress and anxiety. There is evidence that most psychiatric disorders are associated with increased oxidative stress but nothing is reported about the presence of oxidative stress in mobbing victims. This study has been carried out in a group of 19 patients affected by workplace mobbing-due adjustment disorders, in comparison with 38 healthy subjects, to evaluate whether oxidative stress may be induced by mobbing. Serum levels of protein carbonyl groups and of nitrosylated proteins, biological markers of oxidative stress conditions, were higher than those measured in healthy subjects. These findings may contribute to a better understanding of the redox homeostasis dysregulation occurring in victims of workplace mobbing.

    Songbird auditory areas (i.e., CMM and NCM) are preferentially activated to playback of conspecific vocalizations relative to heterospecific and arbitrary noise [1]–[2]. Here, we asked if the neural response to auditory stimulation is not simply preferential for conspecific vocalizations but also for the information conveyed by the vocalization. Black-capped chickadees use their chick-a-dee mobbing call to recruit conspecifics and other avian species to mob perched predators [3]. Mobbing calls produced in response to smaller, higher-threat predators contain more “D” notes compared to those produced in response to larger, lower-threat predators and thus convey the degree of threat of predators [4]. We specifically asked whether the neural response varies with the degree of threat conveyed by the mobbing calls of chickadees and whether the neural response is the same for actual predator calls that correspond to the degree of threat of the chickadee mobbing calls. Our results demonstrate that, as degree of threat increases in conspecific chickadee mobbing calls, there is a corresponding increase in immediate early gene (IEG) expression in telencephalic auditory areas. We also demonstrate that as the degree of threat increases for the heterospecific predator, there is a corresponding increase in IEG expression in the auditory areas. Furthermore, there was no significant difference in the amount IEG expression between conspecific mobbing calls or heterospecific predator calls that were the same degree of threat. In a second experiment, using hand-reared chickadees without predator experience, we found more IEG expression in response to mobbing calls than corresponding predator calls, indicating that degree of threat is learned. Our results demonstrate that degree of threat corresponds to neural activity in the auditory areas and that threat can be conveyed by different species signals and that these signals must be learned.

    Although mobbing has been extensively studied, empirical research has not led to firm conclusions regarding its antecedents and consequences, both at personal and organizational levels. An extensive literature search yielded 86 empirical studies with 93 samples. The matrix correlation obtained through meta-analytic techniques was used to test a structural equation model. Results supported hypotheses regarding organizational environmental factors as main predictors of mobbing.

  19. Nuthatches eavesdrop on variations in heterospecific chickadee mobbing alarm calls

    Many animals recognize the alarm calls produced by other species, but the amount of information they glean from these eavesdropped signals is unknown. We previously showed that black-capped chickadees (Poecile atricapillus) have a sophisticated alarm call system in which they encode complex information about the size and risk of potential predators in variations of a single type of mobbing alarm call. Here we show experimentally that red-breasted nuthatches (Sitta canadensis) respond appropriately to subtle variations of these heterospecific “chick-a-dee” alarm calls, thereby evidencing that they have gained important information about potential predators in their environment. This study demonstrates a previously unsuspected level of discrimination in intertaxon eavesdropping. PMID:17372225

    To evaluate the advancement of knowledge on the impact of an empowering leadership style on the risk of mobbing behaviour among nurse working teams. The secondary aim was to evaluate, along with leadership style, the contribution of other organisational- and individual-related mobbing predictors. The style of leadership in reducing the onset of mobbing risk in nurse working teams still remains a matter of discussion. Nurse working teams are particularly affected by mobbing and studies exploring individual and organisational inhibiting/modulating factors are needed. An empirical study involving 175 nurses of various public hospital corporations in northern Italy. Data were collected via structured and anonymous questionnaires and analysed through a logistic regression. Organisational, individual and participative leadership variables explained 33.5% (P leadership enacted by nursing managers and the nursing shortage as perceived by clinical nurses. Results confirmed that the contribution made by a participative leadership style in attenuating the onset of mobbing risk in working teams was significant. A participative leadership style adopted by the nurse manager allows for the reduction of tensions in nurse working teams. However, mobbing remains a multifaceted phenomenon that is difficult to capture in its entirety and the leadership style cannot be considered as a panacea for resolving this problem in nurse working teams. © 2013 John Wiley & Sons Ltd.

  1. Mobbing calls signal predator category in a kin group-living bird species

    Griesser, Michael

    2009-01-01

    Many prey species gather together to approach and harass their predators despite the associated risks. While mobbing, prey usually utter calls and previous experiments have demonstrated that mobbing calls can convey information about risk to conspecifics. However, the risk posed by predators also differs between predator categories. The ability to communicate predator category would be adaptive because it would allow other mobbers to adjust their risk taking. I tested this idea in Siberian jays Perisoreus infaustus, a group-living bird species, by exposing jay groups to mounts of three hawk and three owl species of varying risks. Groups immediately approached to mob the mount and uttered up to 14 different call types. Jays gave more calls when mobbing a more dangerous predator and when in the presence of kin. Five call types were predator-category-specific and jays uttered two hawk-specific and three owl-specific call types. Thus, this is one of the first studies to demonstrate that mobbing calls can simultaneously encode information about both predator category and the risk posed by a predator. Since antipredator calls of Siberian jays are known to specifically aim at reducing the risk to relatives, kin-based sociality could be an important factor in facilitating the evolution of predator-category-specific mobbing calls.

    Workplace mobbing, a particular type of conflict, has recently been recognized as one of the factors of occupational hazard, resulting from the social environment. Health service workers belong to occupational groups, which are particularly exposed to mobbing. Moreover, changes in the structure of medical labor market make that nurses often work under strong pressure and thus the phenomenon of mobbing becomes even more intensified. The aim of this study was to analyze the incidence of mobbing in the nursing stuff employed in the Szczecin hospitals. The method of diagnostic poll was based on a questionnaire, developed and distributed among 1578 respondents employed in hospitals in Szczecin. Of this number, 1261 correctly completed questionnaires were statistically analyzed. The results showed that the phenomenon of mobbing is actually common in the nursing occupational group (18.6%). The majority (40%) of respondents indicated a superior as a mobber (torturer). The high incidence of mobbing observed in the nursing occupational group may evidence that Human Resource Management (HRM) processes are not perfect.

    In the present study in secondary schools and hospitals in Uruguay (N = 187), we examined the relationship between feeling the victim of mobbing and a perceived loss of status. Nearly all forms of mobbing were more prevalent among hospital employees than among school employees. Among hospital employees, 40.4%, and among school employees, 23.9% reported being the victim of mobbing at least once a week. Being the victim of mobbing was, in both hospitals and schools, more prevalent among older employees, and in hospitals, among employees who were more highly educated and who had been employed for a longer time. Men and women did not differ in reporting that one was a victim of mobbing, but men reported more perceived loss of status than women. However, among women, being the victim of mobbing was much more strongly related to experiencing a loss of status than among men. Several explanations for this gender difference and the practical and theoretical implications of the results are discussed. © The Author(s) 2016.

  11. Interspecific reciprocity explains mobbing behaviour of the breeding chaffinches, Fringilla coelebs.

    Science.gov (United States)

    Krams, Indrikis; Krama, Tatjana

    2002-01-01

    When prey animals discover a predator close by, they mob it while uttering characteristic sounds that attract other prey individuals to the vicinity. Mobbing causes a predator to vacate its immediate foraging area, which gives an opportunity for prey individuals to continue their interrupted daily activity. Besides the increased benefits, mobbing behaviour also has its costs owing to injuries or death. The initiator of mobbing may be at increased risk of predation by attracting the predator's attention, especially if not joined by other neighbouring prey individuals. Communities of breeding birds have always been considered as temporal aggregations. Since an altruist could not prevent cheaters from exploiting its altruism in an anonymous community, this excluded any possibility of explaining mobbing behaviour in terms of reciprocal altruism. However, sedentary birds may have become acquainted since the previous non-breeding season. Migrant birds, forming anonymous communities at the beginning of the breeding season, may also develop closer social ties during the course of the breeding season. We tested whether a male chaffinch, a migrant bird, would initiate active harassment of a predator both at the beginning of the breeding season and a week later when it has become a member of a non-anonymous multi-species aggregation of sedentary birds. We expected that male chaffinches would be less likely to initiate a mob at the beginning of the breeding season when part of an anonymous multi-species aggregation of migratory birds. However, their mobbing activity should increase as the breeding season advances. Our results support these predictions. Cooperation among individuals belonging to different species in driving the predator away may be explained as interspecific reciprocity based on interspecific recognition and temporal stability of the breeding communities.

    The problem of mobbing has attracted a great deal of attention over the past few years. This concern has increased the study of the phenomena, which has resulted in many scientific publications. Mobbing has been characterised as an emerging risk at work. The aim of this longitudinal study was to analyse the influence of mobbing on depressive symptoms in a sample of employees working with people with intellectual disabilities (ID). The sample consisted of 372 Spanish employees working with people with ID at 61 job centres in the Valencian Community (Spain). Seventy-nine (21.2%) participants were men, and 293 were (78.8%) women. Mobbing was evaluated by the Mobbing-UNIPSICO scale, and depressive symptoms were measured using the Zung Self Rating Depression Scale. Using analyses of variance (anova), we tested the differences in depressive symptoms according to the mobbing criteria indicated by Leymann, that is, frequency and duration at Time 1 and Time 2. Employees who met the mobbing criteria: frequency (at least once a week) and duration (at least 6 months) at the two study times presented significantly higher levels of depressive symptoms than employees who met mobbing criteria at Time 1, but did not meet any criteria for mobbing at Time 2, and employees who did not meet any criteria for mobbing at Time 1 or Time 2. We conclude that permanence of mobbing from Time 1 to Time 2 increases depressive symptoms. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Full Text Available Anti-predator behaviour of magpies was investigated, using five species of model predators, at times of raising offspring. We predicted differences in mobbing strategies for each predator presented and also that raising juveniles would affect intensity of the mobbing event. Fourteen permanent resident family groups were tested using 5 different types of predator (avian and reptilian known to be of varying degrees of risk to magpies and common in their habitat. In all, 210 trials were conducted (across three different stages of juvenile development. We found that the stage of juvenile development did not alter mobbing behaviour significantly, but predator type did. Aerial strategies (such as swooping were elicited by taxidermic models of raptors, whereas a taxidermic model of a monitor lizard was approached on the ground and a model snake was rarely approached. Swooping patterns also changed according to which of the three raptors was presented. Our results show that, in contrast to findings in other species, magpies vary mobbing strategy depending on the predator rather than varying mobbing intensity.

    Full Text Available Systematic, permanent, time-staggered hostile behavior towards an employee are just some of the features of the phenomenon known as mobbing. Such behaviors lead to mental and often physical destruction. We meet with them every day because it has been accompanied by hostility since the beginning of its existence, as an emotion, and the need to acquire and overcome. The motives of applying such behaviors depend not only on the internal characteristics of the human being that enable him to meet his needs. In a professional environment, it is the lack of appropriate rules of mutual coexistence, consent to such behavior by concealing their occurrence as well as deliberate actions. The article presents the phenomenon of mobbing in the practice of Polish enterprises. It indicates what is mobbing and what behaviors are legally recognized as mobbing. It presents the size of this phenomenon in Poland, its causes as well as the effects of using mobbing for an employee and an entrepreneur. In this article, the author is based on the literature available in this area, compares the research conducted by CBOS in 2002 and 2014, as well as the research by HR Sedlak & Sedlak, from 2015, and tries to complement this multidimensional problem with its perception by the serial employees.

    To identify relationships among variables affecting nurses' performance and productivity, namely professional attitudes, organisational culture, organisational justice and exposure to mobbing. The determination of the factors affecting performance and productivity is important for providing efficient nursing services. These factors have been investigated in the literature independently, but the relationship among them has not been clearly identified. This cross-sectional questionnaire study included 772 nurses working in a University Hospital accredited by Joint Commission International. The professional attitude score of the nurses was high (4.35 ± 0.63). However, their organisational justice (2.22 ± 1.26) and organisational culture (2.47 ± 0.71) scores were low. Nurses were subjected to mobbing at a high level (0.82 ± 0.78). As the organisational justice increased, the organisational culture increased and the mobbing decreased. As the organisation culture decreased, the mobbing increased. There was a positive correlation between organisation culture and organisational justice of the nurses and a negative correlation with mobbing. The results of the study are essential for improving nurses' performance and productivity. © 2016 John Wiley & Sons Ltd.

    2008-04-01

    We compared the mobbing response to model snakes of two groups of captive-born common marmosets (Callithrix jacchus) differing in genetic relatedness, age and past experience. Mobbing vocalisations (tsik calls), other mobbing behaviour and attention to the stimulus were recorded for 2 min. intervals pre-exposure, during exposure to various stimuli and post-exposure. Marmosets in one group were vocally reactive to all stimuli, although more so to one particular stimulus resembling rearing snakes and modified images of it, whereas the marmosets in a younger and genetically unrelated group attended to the stimuli but made very few mobbing calls. The parent stock of the first group had suffered stress in early life and had developed a phobic response to a specific stimulus, which they had transmitted to their offspring. A third group, matching the older group in age range but genetically unrelated, was also found to be unresponsive to the stimulus that elicited the strongest response in the first group. Cortisol levels in samples of hair were assayed and a significant negative correlation was found between the number of tsik calls made during presentation of the stimuli and the cortisol level, showing that mobbing behaviour/behavioural reactivity is associated with low levels of physiological stress.

    The attention of international agencies and scientific community on mobbing (bullying) and work-related stress is increasing. However, research on gender differences and etiologic agents is still limited. This study describes the gender differences found in victims of mobbing and work-related stress in an Italian case series. Between 2001 and 2009, at the Occupational Medicine Unit of our Institution we examined 345 outpatients (197 women and 148 men) for suspected psychopathological work-related problems. After interdisciplinary diagnostic evaluation, the diagnosis of "mobbing syndrome" was formulated, according to international criteria (ICD-I0 and DSM-IV), in a minority of cases: 35 subjects. In the other workers, we found pre-existing psychiatric conditions (not related to work), or altered relationships dynamics with the colleagues. Significant gender differences emerged among people with "mobbing syndrome": there was a high prevalence of women (65%), with medium to high level of education; the most affected age group was between 34 and 45 years; several occupations were involved, with a clear preponderance of office workers. Women are mostly harassed for personal aspects related to emotional and relational factors; men for the content of their work. The knowledge of the phenomenon is an essential prerogative to contrast mobbing; this can be realized, at a preventive level, only through effective information and training for workers and employers, who have the legal obligation to preserve the integrity of the mental and physical status of their employees during the work.

    Using three elementary substances, Mo, Ni, and amorphous B as raw materials, four series of Mo 2 NiB 2 -based cermets with the Mo/B atomic ratio ranging from 0.9 to 1.2 were successfully prepared via reaction sintering. The effect of Mo/B atomic ratio on the microstructure and properties was studied for the cermets. The results indicate that there is a strong correlation between the Mo/B atomic ratio and properties. The transverse rupture strength of the cermets increases with an increase in Mo/B ratio and shows a maximum value of 1 872 MPa at an Mo/B atomic ratio of 1.1 and then decreases with increasing Mo/B atomic ratio. The hardness and the corrosion resistance of the cermets increase monotonically with an increase in Mo/B atomic ratio. In Mo-rich cermets with an atomic ratio of Mo/B above 1.1, a small amount Ni-Mo intermetallic compound is found precipitated at the interface of Mo 2 NiB 2 grains.

    Mobbing is a type of violence which occurs in workplaces and is classified under the community violence subgroup of interpersonal violence. The aim of this study is to examine health care workers who work in primary health care in the city of Mugla and to determine whether there is a relationship between sociodemographic characteristics, work conditions, and their level of mobbing. A cross-sectional analysis has been conducted in which 130 primary health care workers were selected. Of the 130, 119 health workers participated, yielding a response rate of 91.5%; 83.2% of health workers are female, 42.9% are midwives, 27.7% are nurses, and 14.3% are doctors. In all, 31.1% of health workers have faced with "mobbing" in the last 1 year, and the frequency of experiencing "mobbing" of those 48.6% of them is 1 to 3 times per year. A total of 70.3% of those who apply "mobbing" are senior health workers, and 91.9% are female. The frequency of encountering with "mobbing" was found significantly in married health workers, in those 16 years and above according to examined total working time, in those who have psychosocial reactions, and in those who have counterproductive behaviors. It has been discovered that primary health care workers have high prevalence of "mobbing" exposure. To avoid "mobbing" at workplace, authorities and responsibilities of all employees have to be clearly determined. © The Author(s) 2015.

    Bullying is a manifestation of occupational stress and can therefore be considered as a real "organizational pathology." Include the activities of the surgery dedicated to Mobbing, Unit of Occupational Medicine Sant'Andrea Hospital, which began operations in June 2001. In over ten years of operation (July 2012), the sample, consisting of 50.7% for men and 49.3% women, is heterogeneous in age. The schooling of the sample is medium-high as more than 82% have higher education level. The business sector is the service sector accounted for most (84%) than in industry (9%) and agriculture (2%). Of the 1545 patients seen, 1320 completed the diagnostic path, while 225 have stopped. 814 users have been certified for compatibility bullying (63% of cases) with a net reduction of the awards from 2007 onwards. Considerations are expressed about the possible intervention strategies: the presence of dedicated experts at the counters of listening and professionals as the trusted advisor, to which workers in distress can call on for advice and guidance on how to defend itself from, in accordance with the implemented for years at the Ministry of Health, the establishment of such figures as the manager rehability that in other European countries, are scheduled for some time in work organization.

    2003-05-01

    Previous acoustic analyses suggested emotion-correlated changes in the acoustic structure of squirrel monkey (Saimiri sciureus) vocalizations. Specifically, calls given in aversive contexts were characterized by an upward shift in frequencies, often accompanied by an increase in amplitude. In order to test whether changes in frequencies or amplitude are indeed relevant for conspecific listeners, playback experiments were conducted in which either frequencies or amplitude of mobbing calls were modified. Latency and first orienting response were measured in playback experiments with six adult squirrel monkeys. After broadcasting yaps with increased frequencies or amplitude, squirrel monkeys showed a longer orienting response towards the speaker than after the corresponding control stimuli. Furthermore, after broadcasting yaps with decreased frequencies or amplitude, squirrel monkeys showed a shorter orienting response towards the speaker than after the corresponding manipulated calls with higher frequencies or amplitude. These results suggest that changes in frequencies or amplitude were perceived by squirrel monkeys, indicating that the relationship between call structure and the underlying affective state of the caller agreed with the listener's assessment of the calls. However, a simultaneous increase in frequencies and amplitude did not lead to an enhanced response, compared to each single parameter. Thus, from the receiver's perspective, both call parameters may mutually replace each other.

La muestra está compuesta por 696 trabajadores (142 hombres y 547 mujeres. La frecuencia de acciones de mobbing fueron evaluadas mediante una escala compuesta por 21 ítems que recogen cuatro tipos de acciones: imposibilidad de comunicación adecuada, acciones contra la reputación personal, acciones contra el desempeño del trabajo, y acciones que comprometen la salud. Los resultados psicométricos sobre el instrumento (análisis factorial y consistencia interna fueron adecuados, discriminando entre sujetos en situación de mobbing y sujetos que no presentaban mobbing, según criterio de frecuencia y duración. La prevalencia de mobbing fue del 18.97% (n = 132. No se obtuvieron diferencias significativas entre víctimas y no víctimas con respecto al género, pero sí se obtuvieron diferencias significativas en función de la antigüedad en la organización y del tipo de contrato, pues las víctimas presentaban mayor antigüedad y un contrato más estable que las no víctimas. Estos resultados llevan a concluir que las acciones de mobbing pueden estar relacionadas con políticas y prácticas empresariales como el despido o la reducción de plantilla.

    Despite its highly detrimental potential, most standard questionnaires assessing psychosocial stress at work do not include mobbing as a risk factor. In the German standard version of COPSOQ, mobbing is assessed with a single item. In the Gutenberg Health Study, this version was used together with a newly developed short scale based on the Leymann Inventory of Psychological Terror. The purpose of the present study was to evaluate the psychometric properties of these two measures, to compare them and to test their differential impact on relevant outcome parameters. This analysis is based on a population-based sample of 1441 employees participating in the Gutenberg Health Study. Exploratory and confirmatory factor analyses and reliability analyses were used to assess the mobbing scale. To determine their predictive validities, multiple linear regression analyses with six outcome parameters and log-binomial regression models for two of the outcome aspects were run. Factor analyses of the five-item scale confirmed a one-factor solution, reliability was α = 0.65. Both the single-item and the five-item scales were associated with all six outcome scales. Effect sizes were similar for both mobbing measures. Mobbing is an important risk factor for health-related outcomes. For the purpose of psychosocial risk assessment in the workplace, both the single-item and the five-item constructs were psychometrically appropriate. Associations with outcomes were about equivalent. However, the single item has the advantage of parsimony, whereas the five-item construct depicts several distinct forms of mobbing.

    Living in a region of imminent threat of a magnitude-9.0 (M­­­w ≈ ­9) earthquake is a daily reality for the millions of people predicted to be directly affected by a full rupture of the Cascadia Subduction Zone (CSZ), a fault line extending for hundreds of miles off the western coast of North America. Many coastal residents and visitors will also be affected by the tsunami caused by the rupture. How can the scientific community effectively communicate with those who are unaware of the threat and unprepared to respond? We are studying the effects of a novel approach to science outreach we have called Flash Mob Science. You have probably seen examples of flash mobs staging dynamic musical and dance routines to unsuspecting audiences. Similarly, Flash Mob Science takes the challenging (and often avoided) topic of earthquake and tsunami awareness and preparedness to unsuspecting audiences. However, Flash Mob Science seeks to move beyond having an audience of observers by engaging others as participants who enact important roles in an unfolding drama. We simulate the effects of seismic and tsunami events (e.g., prolonged surface shaking, falling debris, repeated tsunami surges) and model best practices in response (e.g., "Drop, Cover, Hold On" and moving quickly to high ground). True to the general flash mob model, when the Cascadia event inevitably does occur, it will come suddenly, and everyone affected will unavoidably be involved as actors in a real-life drama of immense scale. We seek to embed the learning of basic understandings and practices for an actual Cascadia event in a very small-scale, memorable, and sometimes even humorous, dramatization. We present here the lessons we have learned in the background, planning, and implementation of Flash Mob Science. We highlight the successes, limitations, and preliminary results evaluating the effectiveness of this outreach in developing learners' understandings and preparedness in an Oregon community affected by

    The number of mobbing experiences recorded has increased during recent years and it has now been established as global phenomenon among the working population. The goal of our study was to analyze the incidence of certain neurologic and psychiatric diseases as a consequence of mobbing as compared with a control group and to examine the possible influence of previous diseases that occurred within one year before the first mobbing documentation on the incidence of mobbing. We used a large database (IMS® Disease Analyzer, Germany) to collect data from general practitioners in Germany from 01/2003 until 12/2012. Based on age, gender, and health insurance, patients with experience of mobbing were matched with a control group of patients who had not reported workplace mobbing and who were being treated by the same physicians. At first, diseases that occurred within one year before the bullying experience took place ("index date") were noted and compared to a control group of similar composition in terms of gender, age, and health insurance. Subsequently, the prevalence of depression, anxiety, somatoform disorders, and sleep disorders following experiences of mobbing were determined. After adjustment to take into account the odds of bullying, the ratios of these diseases were assessed using a logistic regression model. The study population consisted of n=2,625 patients and n=2,625 controls, of which 33% were men. The number of cases of bullying documented rose continuously from 2003 to 2011 and remained high in 2012. Those who would later become victims of mobbing demonstrated a considerably higher prevalence of diseases in general - these diseases were not confined to the neurologic-psychiatric spectrum. Following experiences of bullying, depression, anxiety, somatoform disorders, and sleep disorders were significantly more prevalent than in the control group (for all, pmobbing has occurred, which underlines the importance of supporting (chronically) ill patients to

  14. The Course of Law: State Intervention in Southern Lynch Mob Violence 1882–1930

    Directory of Open Access Journals (Sweden)

    Kinga Makovi

    2016-09-01

    Full Text Available Collective violence when framed by its perpetrators as "citizen" justice is inherently a challenge to state legitimacy. To properly account for such violence, it is necessary to consider an opportunity structure incorporating the actions of both vigilantes and agents of the state. The motivation and lethality of lynch mobs in the South cannot be understood without considering how the state reacted to the legitimacy challenges posed by lynching. We trace the shifting orientation of state agents to lynching attempts between the end of Reconstruction and the start of the Great Depression. Analyzing an inventory of more than 1,000 averted and completed lynching events in three Southern states, we model geographic and temporal patterns in the determinants of mob formation, state intervention, and intervention success. Opponents of lynching often pled with mobs to "let the law take its course." This article examines the course followed by the law itself, as state actors moved between encouraging, accommodating, and in many instances averting mob violence.

    The aim of this study was to determine the frequency of and risk factors for physical violence, verbal violence, and mobbing experienced by nurses in a university hospital. This was a cross-sectional study conducted at Gazi University Medical Faculty Hospital. A questionnaire form recommended by the WHO and the International Labor Organization was administered through face-to-face interviews to determine the violence experienced in the past 12 months by nurses. The prevalence of physical violence, verbal violence, and mobbing was 13.9%, 41.8%, and 17.1%, respectively. Working more than 40 h per week increased the risk of physical violence by 1.86 times. The majority of nurses who experienced verbal violence and mobbing were significantly more willing to change their work, their institution, and their profession if given the opportunity. Fewer than one-fourth of the victims indicated they reported any incident. We knew that the prevalence of physical violence, verbal violence, and mobbing were high among nurses and that incidents were underreported, and the study corroborated this information. What this study adds to the topic is that long working hours increased the prevalence of physical violence and was defined as an important contributory factor.

    This study aimed to develop and evaluate the effects of a sexual abuse prevention mobile application, SAP_MobAPP, for primary school children. Forty-five subjects were trained for 40 minutes once a week. The experimental group received education that utilized the SAP_MobAPP. Control group A received Web based sexual abuse prevention education, while control group B received textbook based sexual abuse prevention education. Effectiveness was verified through a survey on child sexual abuse recognition and avoidance skills administered before and after training. The SAP_MobAPP program improved recognition (awareness) and the child's skills to avoid child sexual abuse situations, and the effects were long-lasting. However, differences between groups were not statistically significant. This study developed a sexual abuse prevention application and verified its effectiveness. Awareness and skills to avoid child sexual abuse after app education increased immediately after training and four weeks later. The SAP_MobAPP could be used for sexual abuse prevention education in schools.

  19. Mobbing and sitting tight at the nest as methods of avoiding brood parasitism.

    Science.gov (United States)

    Rands, Sean A

    2012-04-06

    The arms race between brood parasites and their hosts has led to many different host behaviours for avoiding parasitism. Some of these behaviours are social, and require the presence of conspecifics to work effectively: in response to alarm calls, some species engage in mobbing behaviour where neighbours join nest tenants in attacking and repelling an invading brood parasite. There are risks involved for the neighbours, but it has been demonstrated that social mobbing allows individuals to learn about the presence of brood parasites in the environment, suggesting that social learning is occurring. Here, I consider whether using social signals to alert naive individuals to the presence of brood parasites is a suitable strategy, compared with sitting tight on the nest in response to the signal (which should reduce the chances of being parasitized). I also compare the efficiency of these strategies with the case where individuals fail to change behaviour in response a brood parasite. Using an individual-based simulation model, I demonstrate that both mobbing and sitting tight are effective strategies in response to a signal, and that mobbing is more effective when the chances of being parasitized increase. These results are discussed and compared with known host-brood parasite relationships.

    Mobbing, or psychological harassment at the workplace, is usually defined as a situation in which a person or a group of people engage in extreme psychological violence against another person. In Spain, the number of reports for mobbing has increased extraordinarily in the last years. The reports are increasing dramatically not only before the Labour Courts, but also before the Civil Courts, with claims for damages, and before the Penal Court for offences causing physical or moral injury, etc., since at the present time this figure is not typified as an offence in the Spanish Penal Code. The high degree of complexity of this situation has given rise to frequent misuse of the term and to a number of false accusations of mobbing. A recent European Parliament Resolution on harassment at the workplace addressed the devastating consequences of false accusations. In this paper we present a case in which the "false" victim was mentally ill (paranoia) but succeed in generating an extreme dangerous environment of great harassment against the "false" assailants that were "falsely" accused of mobbing. Forensic diagnosis of the psychiatric disorder suffered by the "false" victim was essential to clarify the issue at the Penal Court.

    INTRODUCTION. The relationship between stressful events in the workplace and their effect on health is the subject of numerous studies where the phenomenon of"Mobbing" has become of increasing interest in Social Psychiatry and Occupational Medicine. The aim of this study is to evaluate the relationship between mobbing, occupational stress and personality structure in a group of persons who consulted the "Work Adaptation Disorders Centre" at the Institute of Occupational Medicine between December 2008 and June 2010 for mobbing-related issues. Referring to Leymann Inventory of Psychological Terrorization (LIPT), H. Ege, Occupational Stress Indicator (OSI), Minnesota Multiphasic Personality Inventory 2 (MMPI-2), it has been possible to assess situations of harassment, the sources and the effects of work stress, as well as personality traits in the study group. The results showed that high levels of occupational stress and inadequate coping strategies can lead to depressive, hysterical and paranoid manifestations. Although the relationship between mobbing, occupational stress and personality traits still remains controversial, there is an association between perception of adverse behaviour and mental health, regardless of the subject's ability to cope with stressful life events. The data seem to confirm that the prevention of bullying must be implemented by the work organization and by handling interpersonal conflicts in the work context.

    to determine the perception of verbal abuse and mobbing and the associated factors of paramedic technicians (nursing assistants) and professionals (nurses, midwives, kinesiologists) in the pre-hospital care areas of three regions in the south of Chile. descriptive and correlational study was performed within the professional community and a two-stage sample of the paramedic technician population in three regions. The questionnaire "workplace violence in the health sector" (spanish version) was applied after signing the informed consent. 51.4% of professionals and 46.6% of paramedic technicians consider they have been verbally abused during last year. 17.6% of paramedic technicians and 13.5% of professionals perceived mobbing. A low percentage of these events are reported. In only one case of mobbing, the aggressor was legally penalized. No significant differences were found between the job categories and the studied regions. A high percentage of participants in each group perceived verbal abuse and non-minor percentage perceived mobbing, but most of these events are not reported.

    Mobbing, defined as sustained harassment among workers, in particular towards subordinates, merits investigation. This study aims to investigate Slovenian midwifery students' (2nd and 3rd year students of midwifery at the Faculty for Health Studies Ljubljana; the single educational institution for midwives in Slovenia) perception of mobbing, since management of acceptable behavioural interrelationships in midwifery profession forms already during the study, through professional socialization. Descriptive and causal-nonexperimental method with questionnaire was used. Basic descriptive statistics and measures for calculating statistical significance were carried out with SPSS 20.0 software version. All necessary ethical measures were taken into the consideration during the study to protect participants. The re- sults revealed that several participants experienced mobbing during the study (82.3%); 58.8% of them during their practical training and 23.5% from midwifery teachers. Students are often anxious and nervous in face of clinical settings (60.8%) or before faculty commitments (exams, presentations etc.) (41.2%). A lot of them (40.4%) estimate that mobbing affected their health. They did not show effective strategies to solve relationship problems. According to the findings, everyone involved in midwifery education, but above all students, should be provided with more knowledge and skills on successful management of conflict situations.

    Mobbing is a phenomenon produced for the most part by factors related to work organization. During the medical control of workers in Universitary Policlinico Hospital of Palermo, we used a methodology (in advance applied with effectiveness by ISPESL in other institutions) that is able to evidence factors of work organization causing Mobbing. 338 out 2060 workers (total staff) with different professional figures were recruited. We evidenced the working classes that had more troubles about communications of business information, about interpersonal relationships at work with top manager, with other members of team and with colleagues. Particularly doctors and OTA, in worrying percentage, stated that they suffered psychological molestations. Aim of our study was to assay a procedure that, even if it doesn't identify proclaimed mobbing phenomenon, enables us to acquire information about relationships between business management and workers and organizational aspects perceiving by subordinates. A I level study about a phenomenon in expansion is very useful to recognize preventively intentionally made mobbing actions.

    Over the last decade a consistent increase in stress-related psychological consequences at the workplace, usually called 'mobbing', has been seen. It claimed physical, psychical and social distress as its victims, leading to an increased incidence of many illnesses, such as psychosomatic disorders (ache, high blood pressure, chronic fatigue and insomnia) and psychiatric disturbances (high level of anxiety, depression and suicidal attempts). It was recently demonstrated that mobbing is significantly widespread among healthcare workers, especially among female nurses. In this report, we illustrate the case of a nurse who, after a brilliant career, underwent mobbing at the workplace, showing depression, anxiety and sleep disorders that required hospitalisation and a substantial intervention.

    Full Text Available In a Flash Mob (FM a group of people get together in the physical world perform an unpredicted act and disperse quickly. Cyber Flash Mob (CFM is the cyber manifestation of flash mob coordinated primarily using social media. Deviant Cyber Flash Mob (or, DCFM is a special case of CFM, which is categorized as the new face of transnational crime organizations (TCOs. The DCFM phenomenon can be considered as a form of a cyber-collective action that is defined as an action aiming to improve group's conditions (such as, status or power. In this paper, we conduct a conceptual analysis of the DCFMs and model the factors that lead to success or failure with groundings in collective action and collective identity formation theories. Mathematical constructs of hypergraph are leveraged to represent the complex relations observed in the DCFM social networks. The model's efficacy is demonstrated through a test scenario.

    Work is undoubtedly fundamental to human life, social development and the economic development of individuals, organizations and nations. However, the experience of working is not always pleasant as there are many instances where relationships between workers could deteriorate, leading to practices and behaviours that could be characterized as workplace bullying and/or mobbing. The current study is an exploratory study which used autoethnography to investigate experiences of academic bullying and mobbing, and relates the practices to power structures in academic institutions. Specifically, the author shares personal experiences and explores the physical and emotional pain of being bullied and mobbed. The author also outlines how both autoethnography and meaning in life strategies were used to cope with the physical and emotional distresses associated with the negative experiences. By outlining the success of the meaning in life strategies, the author hopes to inspire other "victims" to move from victims to being survivors of bullying and mobbing.

  10. The Possible Crosstalk of MOB2 With NDR1/2 Kinases in Cell Cycle and DNA Damage Signaling.

    This article is the authors' opinion of the roles of the signal transducer Mps one binder 2 (MOB2) in the control of cell cycle progression and the DNA Damage Response (DDR). We recently found that endogenous MOB2 is required to prevent the accumulation of endogenous DNA damage in order to prevent the undesired, and possibly detrimental, activation of cell cycle checkpoints. In this regard, it is noteworthy that MOB2 has been linked biochemically to the regulation of the NDR1/2 (aka STK38/STK38L) protein kinases, which themselves have functions at different steps of the cell cycle. Therefore, we are speculating in this article about the possible connections of MOB2 with NDR1/2 kinases in cell cycle and DDR Signaling.

    A crucial element in the horizontal transfer of mobilizable and conjugative plasmids is the relaxase, a single-stranded endonuclease that nicks the origin of transfer (oriT) of the plasmid DNA. The relaxase of the pMV158 mobilizable plasmid is MobM (494 residues). In solution, MobM forms a dimer through its C-terminal domain, which is proposed to anchor the protein to the cell membrane and to participate in type 4 secretion system (T4SS) protein-protein interactions. In order to gain a deeper insight into the structural MobM requirements for efficient DNA catalysis, we studied two endonuclease domain variants that include the first 199 or 243 amino acid residues (MobMN199 and MobMN243, respectively). Our results confirmed that the two proteins behaved as monomers in solution. Interestingly, MobMN243 relaxed supercoiled DNA and cleaved single-stranded oligonucleotides harboring oriTpMV158, whereas MobMN199 was active only on supercoiled DNA. Protein stability studies using gel electrophoresis and mass spectrometry showed increased susceptibility to degradation at the domain boundary between the N- and C-terminal domains, suggesting that the domains change their relative orientation upon DNA binding. Overall, these results demonstrate that MobMN243 is capable of nicking the DNA substrate independently of its topology and that the amino acids 200 to 243 modulate substrate specificity but not the nicking activity per se. These findings suggest that these amino acids are involved in positioning the DNA for the nuclease reaction rather than in the nicking mechanism itself.

    Abstract: Background: Mobbing (bullying at work) refers to a form of psychological harassment that occurs in the workplace, in which the victim must be systematically and continuously persecuted for a long period of time. The aim of this work is to analyze the court judgments related to mobbing. Methods: The data, collected from a website that included judgments from an Italian court, were analyzed according to the literature, identifying the type of victims, consequences, methods of harassment, type of mobbers, and compensation decided by the court. Results: A total of 35 court sentences were analyzed. The findings showed that the duration of the mobbing campaign was on average 1.5 years and that the frequency of harassment was every day in most cases. In the majority of cases (17, 48.6%) the mobbing occurred in a private company. The gender of the victims who reported the mobbing experience was predominantly female (19, 54.3%), and on average, the victims were 44.54 years of age. The victims were classified as captives (12, 34.3%), scapegoats (8, 22.9%), ambitious (8, 22.9%), passives (5, 14.3%) and hypochondriacs (2, 5.7%). The mobbers were predominantly men (25, 71.4%) and on average 53.20 years of age. They were classified as casual (12, 34.3%), sadists (11, 31.4%), instigators (8, 22.9%) and choleric (4, 11.4%). The witnesses were described in the majority of cases as active, while the asymmetry of power was vertical. On average, the victims suffered 4.9 types of harassment, and the most cited consequences were anxiety disorder and physical symptoms. The motives for beginning the mobbing campaign were principally related to difficulties in relationships. The compensation imposed by the court ranged from less than 20,000 to more than 70,000 euros. Conclusions: The sentences analyzed showed that for different types of victims, there are behaviors, motives and consequences that are linked to different types of perpetrators. PMID:29187725

    Full Text Available The aim of the article is to develop propositions regarding the implementation of responsibility for mobbing at the legislative level. The concept of “mobbing”, reasons for its occurrence, indicators of manifestation and consequences for the activity both at the level of the enterprise and from the point of view of an individual are explored. Examples of European countries on the regulation of mobbing at the legislative level, in particular the responsibility for psychological pressure, are considered. Based on the analysis of legal and regulatory documents of foreign countries and the Ukrainian legal framework, it is concluded that it is important to study the problem of psychological abuse and combat it, including at the state level. It is determined that now Ukraine has no legislatively fixed definition of the concept of “mobbing” and, accordingly, the mechanisms for regulating this phenomenon.

    Full Text Available Workplace mobbing as a form of psychological terrorism in the Republic of Macedonia is relatively new phenomenon which in the last decade is causing huge attention in the legal theory and practice. The problem with mobbing has also become an object of interest of the Macedonian’s trade union since they have seen the danger which this unwanted phenomenon causes in the work environment. That is why the trade union, especially the most numerous and the most representative ones in this country, the Federation of trade unions in Macedonia, has taken initiative to introduce a legislative to protect the workers from harassment in the work place in order to prevent psychological terrorism of the employees, as well as protect the workers from this negative phenomenon. This initiative resulted with the adoption of a special law on 29.05.2013. In this paper we are going to try to analyze the legal framework of the protection from psychological harassment in the work place (mobbing in the Republic of Macedonia, in terms of the rights, obligations and responsibilities of the employers and employees regarding the prevention of psychological harassment in the work place, as well as measures and procedures for the protection from psychological harassment in the work place of the employer and the proceedings. While analyzing the legal aspects of the psychological harassment we are going to stay focused in the Labor law and Law on Protection from Harassment in the Workplace.

  20. Naive Juveniles Are More Likely to Become Breeders after Witnessing Predator Mobbing.

    Responding appropriately during the first predatory attack in life is often critical for survival. In many social species, naive juveniles acquire this skill from conspecifics, but its fitness consequences remain virtually unknown. Here we experimentally demonstrate how naive juvenile Siberian jays (Perisoreus infaustus) derive a long-term fitness benefit from witnessing knowledgeable adults mobbing their principal predator, the goshawk (Accipiter gentilis). Siberian jays live in family groups of two to six individuals that also can include unrelated nonbreeders. Field observations showed that Siberian jays encounter predators only rarely, and, indeed, naive juveniles do not respond to predator models when on their own but do when observing other individuals mobbing them. Predator exposure experiments demonstrated that naive juveniles had a substantially higher first-winter survival after observing knowledgeable group members mobbing a goshawk model, increasing their likelihood of acquiring a breeding position later in life. Previous research showed that naive individuals may learn from others how to respond to predators, care for offspring, or choose mates, generally assuming that social learning has long-term fitness consequences without empirical evidence. Our results demonstrate a long-term fitness benefit of vertical social learning for naive individuals in the wild, emphasizing its evolutionary importance in animals, including humans.

    Alarm calls are important defensive behaviors. Here, we report the acoustic spectrum characteristics of alarm calls produced by Hainan gibbons (Nomascus hainanus) inhabiting Bawangling National Nature Reserve in Hainan, China. Analysis of call data collected from 2002-2014 shows that alarm calls are emitted by all family group members, except infants. Alarm behavior included simple short alarming calls (7-10 min) followed by longer variable-frequency mobbing calls lasting 5-12 min. The duration of individual alarming and mobbing calls was 0.078 ± 0.014 s and 0.154 ± 0.041 s at frequency ranges of 520-1000 Hz and 690-3920 Hz, respectively. Alarming call duration was positively associated with group size. The alarm calls can trigger mobbing behavior in Hainan gibbons; this is a defense way of social animals, and first report among the primates' species. The system of vocal alarm behavior described in this critically endangered species is simple and effective.

    Mobbing as a specific form of discrimination which applies only to the labor law, is a very young branch of labor law. It began to develop during the eighties of last century. This kind of psychoterror that appears in the workplace, was first spotted, formulated and diagnosed by the Swedish psychologist of German origin prof. Dr. Heinz Lejman (Heinz Leymann July 17, 1932.; Wolfenbuttel, Germany - 1999 Stockholm, Sweden). Today, the legal regulation of mobbing in terms of prevention, rules of behavior and sanctions is indispensable to every modern democratic state. I'll make a comparison of the legislative regulation provided by BiH with several European Union member states. I will compare the results of a survey conducted by the European Foundation for the Improvement of Living and Working Condition, during the year 2000. In the European Union Member States, with the results of the questionnaire for employees, which I conducted in Bosnia and Herzegovina. The conclusion I came to in this paper is: Bosnia and Herzegovina is lagging behind a lot of European Union member states, both in terms of prevention of mobbing, as well as legislation, that is insufficient to regulate this complex issue. Results of the questionnaire for the employees that I conducted in Bosnia and Herzegovina are devastating and alarming.

    Combustion synthesis in the mode of self-propagating high-temperature synthesis (SHS) was carried out in the Mo-B and Mo-B-Si systems for the preparation of molybdenum boride MoB and the composite of MoB-MoSi 2 from elemental powder compacts. Under a preheating temperature above 150 deg. C , the reaction of Mo with boron in the sample compact of Mo:B = 1:1 is characterized by a planar combustion front propagating in a self-sustaining and steady manner. As the preheating temperature or sample compaction density increased, combustion temperature was found to increase and the propagation rate of the combustion front was correspondingly enhanced. Moreover, the XRD analysis provides evidence of yielding nearly single-phase α-MoB from the Mo-B sample at equiatomic stoichiometry. In the synthesis of MoB-MoSi 2 composites, the starting stoichiometry of the Mo-B-Si powder compact was varied so as to produce the final composites containing 20-80 mol% MoB. It was also found the increase of flame-front velocity and combustion temperature with increasing MoB content formed in the composite. The composition analysis by XRD shows excellent conversion from the Mo-B-Si powder compact to the MoB-MoSi 2 composite through the SHS reaction; that is, in addition to a small amount of Mo 5 Si 3 , the as-synthesized composite is composed entirely of MoB and MoSi 2

    Service process on a site in the health sector does not only bring people and services into contact, but also all other people who share the fate of particular working medium. Although these people should cooperate and care about each other, contributing new merits to humanity with their synergy, meeting of people with the other people from time to time intertwine into a bitter, pain giving relation, like the way it happens with meeting of people with services. Owing to its controversy to humanitarian nature, religious and social values, the pain that human beings cause to one another is occasionally disguised behind a veil, thus turning into a life tragedy for individuals in the background. Mobbing which is commonly a confrontable problem in every workplace means psychological violence, enclosure, harassment, molestation or endurance. This study aims to draw attention to the precautions required to be taken against mobbing activities by analyzing situations of health employees who undergo mobbing actions in Turkey and in the World. To achieve this, the existing studies concerning mobbing in the healthcare sector have been examined. In conclusion; it is determined that mobbing activities towards healthcare workers have limited their communication possibilities, damaged social relations and social image, prevented vocational improvement and destroyed mental health of employees. With respect to mobbing behavior towards health employees, we should adopt a democratic, contributing, and guiding administration style, we should apply organizational justice, excessive work inspections must be reduced, work ethics and social responsibility awareness must be developed, we should clearly determine the duties and responsibilities, physical conditions must be improved and necessary legal arrangements concerning the subject must be made to be able to prevent mobbing.

    Experiments to monitor human brain activity during active behavior record a variety of modalities (e.g., EEG, eye tracking, motion capture, respiration monitoring) and capture a complex environmental context leading to large, event-rich time series datasets. The considerable variability of responses within and among subjects in more realistic behavioral scenarios requires experiments to assess many more subjects over longer periods of time. This explosion of data requires better computational infrastructure to more systematically explore and process these collections. MOBBED is a lightweight, easy-to-use, extensible toolkit that allows users to incorporate a computational database into their normal MATLAB workflow. Although capable of storing quite general types of annotated data, MOBBED is particularly oriented to multichannel time series such as EEG that have event streams overlaid with sensor data. MOBBED directly supports access to individual events, data frames, and time-stamped feature vectors, allowing users to ask questions such as what types of events or features co-occur under various experimental conditions. A database provides several advantages not available to users who process one dataset at a time from the local file system. In addition to archiving primary data in a central place to save space and avoid inconsistencies, such a database allows users to manage, search, and retrieve events across multiple datasets without reading the entire dataset. The database also provides infrastructure for handling more complex event patterns that include environmental and contextual conditions. The database can also be used as a cache for expensive intermediate results that are reused in such activities as cross-validation of machine learning algorithms. MOBBED is implemented over PostgreSQL, a widely used open source database, and is freely available under the GNU general public license at http://visual.cs.utsa.edu/mobbed.

En el presente estudio hemos realizado un análisis de las variables psicológicas de bienestar que están relacionadas con el mobbing en una muestra de 520 trabajadores de los sectores sanitario y educativo con el objetivo de encontrar aquellas que nos permitan diferenciar grupos de sujetos según alto y bajo riesgo de mobbing. Los análisis realizados revelan correlaciones significativas entre mobbing y las demás variables incluidas en el estudio: burnout, satisfacción laboral y bienestar psicológico. Mediante la aplicación de análisis discriminante encontramos que la insatisfacción con la supervisión, el agotamiento emocional, el cinismo y los síntomas depresivos permiten clasificar adecuadamente a los sujetos con alto y bajo riesgo de mobbing.

    There is increasing interest in research, prevention and management of mobbing in the field of occupational psychosocial risks. To describe mobbing and its health effects by analysis of the cases examined from 1997 to 2003 at the Department of Occupational Health "Clinica del Lavoro Luigi Devoto" in Milan. A total of 226 clinical records of patients who reported a mobbing situation when undergoing medical examination were selected out of 2455 patients examined for stress-related disorders. The percentage of women was higher (53.1%) than in men (46.9%) with a prevalent age range of 35-54 years. There was a great variety of jobs, especially white-collars and workers in large service companies. In one third of the cases, mobbing occurred within 4 years from beginning of employment and mostly after company reorganization and management changes. The most frequent negative acts included social isolation and demotion. The most frequent symptoms were exhaustion, sleep, mood and sexual disorders. The number of symptoms was not related to the duration of mobbing but to the number and frequency of negative actions. 61.1% of the subjects took psychotropic drugs. Occupational health physicians play an essential role in primary prevention (information on occupational risks) and in early diagnosis and rehabilitation and could act as mediators between workers and enterprises.

    Bacillus thuringiensis and Bacillus cereus are two important species in B. cereus group. The intensive study of these strains at the molecular level and construction of genetically modified bacteria requires the development of efficient genetic tools. To insert genes into or delete genes from bacterial chromosomes, marker-less manipulation methods were employed. We present a novel genetic manipulation method for B. thuringiensis and B. cereus strains that does not leave selection markers. Our approach takes advantage of the relaxase Mob02281 encoded by plasmid pBMB0228 from Bacillus thuringiensis. In addition to its mobilization function, this Mob protein can mediate recombination between oriT sites. The Mob02281 mobilization module was associated with a spectinomycin-resistance gene to form a Mob-Spc cassette, which was flanked by the core 24-bp oriT sequences from pBMB0228. A strain in which the wild-type chromosome was replaced with the modified copy containing the Mob-Spc cassette at the target locus was obtained via homologous recombination. Thus, the spectinomycin-resistance gene can be used to screen for Mob-Spc cassette integration mutants. Recombination between the two oriT sequences mediated by Mob02281, encoded by the Mob-Spc cassette, resulted in the excision of the Mob-Spc cassette, producing the desired chromosomal alteration without introducing unwanted selection markers. We used this system to generate an in-frame deletion of a target gene in B. thuringiensis as well as a gene located in an operon of B. cereus. Moreover, we demonstrated that this system can be used to introduce a single gene or an expression cassette of interest in B. thuringiensis. The Mob/oriT recombination system provides an efficient method for unmarked genetic manipulation and for constructing genetically modified bacteria of B. thuringiensis and B. cereus. Our method extends the available genetic tools for B. thuringiensis and B. cereus strains.

    Investigation of the equation of state of molybdenum diboride (MoB 2 ) has been performed to 24.1 GPa using synchrotron radiation angle-dispersive x-ray diffraction techniques (ADXRD) in a diamond anvil cell (DAC) at room temperature. Rietveld refinement of the X-ray powder diffraction data reveals that the rhombohedral structure MoB 2 is stable up to 24.1 GPa. The ADXRD data yield a bulk modulus K 0  = 314(11) GPa with a pressure derivative K 0 ′  = 6.4(1.5). The experimental data are discussed and compared to the results of first-principles calculations. In addition, the compressibility of the unit cell axes (a and c axes) of MoB 2 demonstrates an anisotropic property with pressure increasing

    Full Text Available Terrestrial photography is a cost-effective and easy-to-use method for measuring and monitoring spatially distributed land surface variables. It can be used to continuously investigate remote and often inaccessible terrain. We focus on the observation of snow cover patterns in high mountainous areas. The high temporal and spatial resolution of the photographs have various applications, for example validating spatially distributed snow hydrological models. However, the analysis of a photograph requires a preceding georectification of the digital camera image. To accelerate and simplify the analysis, we have developed the "Photo Rectification And ClassificaTIon SoftwarE" (PRACTISE that is available as a Matlab code. The routine requires a digital camera image, the camera location and its orientation, as well as a digital elevation model (DEM as input. If the viewing orientation and position of the camera are not precisely known, an optional optimisation routine using ground control points (GCPs helps to identify the missing parameters. PRACTISE also calculates a viewshed using the DEM and the camera position. The visible DEM pixels are utilised to georeference the photograph which is subsequently classified. The resulting georeferenced and classified image can be directly compared to other georeferenced data and can be used within any geoinformation system. The Matlab routine was tested using observations of the north-eastern slope of the Schneefernerkopf, Zugspitze, Germany. The results obtained show that PRACTISE is a fast and user-friendly tool, able to derive the microscale variability of snow cover extent in high alpine terrain, but can also easily be adapted to other land surface applications.

    Summary In both Sordaria macrospora and Neurospora crassa, components of the conserved STRIPAK (striatin‐interacting phosphatase and kinase) complex regulate cell–cell fusion, hyphal network development and fruiting body formation. Interestingly, a number of Epichloë festucae genes that are required for hyphal cell–cell fusion, such as noxA, noxR, proA, mpkA and mkkA, are also required for the establishment of a mutualistic symbiotic interaction with Lolium perenne. To determine whether MobC, a homologue of the STRIPAK complex component MOB3 in S. macrospora and N. crassa, is required for E. festucae hyphal fusion and symbiosis, a mobC deletion strain was generated. The ΔmobC mutant showed reduced rates of hyphal cell–cell fusion, formed intrahyphal hyphae and exhibited enhanced conidiation. Plants infected with ΔmobC were severely stunted. Hyphae of ΔmobC showed a proliferative pattern of growth within the leaves of Lolium perenne with increased colonization of the intercellular spaces and vascular bundles. Although hyphae were still able to form expressoria, structures allowing the colonization of the leaf surface, the frequency of formation was significantly reduced. Collectively, these results show that the STRIPAK component MobC is required for the establishment of a mutualistic symbiotic association between E. festucae and L. perenne, and plays an accessory role in the regulation of hyphal cell–cell fusion and expressorium development in E. festucae.

    4-Morpholineethanesulfonic acid (MES), 4-morpholinepropanesulfonic acid (MOPS), 3-morpholino-2-hydroxypropanesulfonic acid (MOPSO), and 4-(N-morpholino)butanesulfonic acid (MOBS), are useful for pH control as standard buffers in the physiological region of 5.5-6.7 for MES, 6.5-7.9 for MOPS, 6.2-7.6 for MOPSO, and 6.9-8.3 for MOBS, respectively. On the basis of density measurements at 298.15 K, the apparent molar volumes, V φ , of the above-mentioned buffers in water and in (0.05, 0.16, and 0.25) mol kg -1 aqueous solutions of NaCl, KCl, KBr, and CH 3 COOK have been calculated. The partial molar volumes at infinite dilution, V φ o , obtained from V φ , have been used to calculate the volume of transfer, Δ tr V φ o , from water to aqueous electrolyte solutions. It was found that both V φ o and Δ tr V φ o vary linearly with increasing the number of carbon atoms in the alkyl group side chain of the zwitterionic buffers. These linear correlations have been utilized to estimate the contributions of the zwitterionic end group (morpholinium ion, -SO 3 - ) and -CH 2 - group to V φ o and Δ tr V φ o . The values of V φ o and Δ tr V φ o for some functional group contributions of the zwittierionic buffers with salts have also been reported.

    Both multilayer period thickness expansion and compaction were observed in Mo/B 4 C multilayers upon annealing, and the physical causes for this were explored in detail. Using in situ time-dependent grazing incidence X-ray reflectometry, period changes down to picometer-scale were resolved. It was shown that the changes depend on the thickness of the B 4 C layers, annealing temperature, and annealing time. Although strong stress relaxation during annealing was observed, it was excluded as a cause for period expansion. Auger electron spectroscopy and wide angle X-ray diffraction measurements revealed the growth of interlayers, with associated period changes influenced by the supply of B and C atoms to the growing compound interlayers. For multilayers with a Mo thickness of 3 nm, two regimes were recognized, depending on the deposited B 4 C thickness: in multilayers with B 4 C ≤ 1.5 nm, the supply of additional Mo into the already formed MoB x C y interlayer was dominant and led to densification, resulting in period compaction. For multilayers with B 4 C ≥ 2 nm, the B and C enrichment of interlayers formed low density compounds and yielded period expansion.

    MMPI-2 test is widely used in psychodiagnostic evaluation as well as in the evaluation of psychic pathologies related to psychosocial adversative events in working activities. A more efficacious use of MMPI-2 test in the working context can be achieved by the individuation of indexes able to facilitate the evaluation of mobbing syndrome. This work is based on the analysis of 150 cases (39.7% women and 60.7% men, 30 to 60 years of age), evaluated through an accurate examination of working history and a series of clinic conversations, followed by psychodiagnostic evaluation. The average of T-scores on the clinical scale, the content scale, the PK addition scale and the validation scale were calculated from tests. Pathologic high T-scores on the scales Hs, D. Hy e Pa were found in subjects having positive mobbing anamnesis. These results strongly indicate the presence of clinical specificities in workers exposed to working harassments, and that these specificities can be efficaciously evidenced by the MMPI-2 test.

  2. Strategic variation in mobbing as a front line of defense against brood parasitism.

    Coevolutionary arms races, where adaptations in one party select for counter-adaptations in another and vice versa, are fundamental to interactions between organisms and their predators, pathogens, and parasites [1]. Avian brood parasites and their hosts have emerged as model systems for studying such reciprocal coevolutionary processes [2, 3]. For example, hosts have evolved changes in egg appearance and rejection of foreign eggs in response to brood parasitism from cuckoos, and cuckoos have evolved host-egg mimicry as a counter-response [4-6]. However, the host's front line of defense is protecting the nest from being parasitized in the first place [7-10], yet little is known about the effectiveness of nest defense as an antiparasite adaptation, and its coevolutionary significance remains poorly understood [10]. Here we show first that mobbing of common cuckoos Cuculus canorus by reed warblers Acrocephalus scirpaceus is an effective defense against parasitism. Second, mobbing of cuckoos is a phenotypically plastic trait that is modified strategically according to local parasitism risk. This supports the view that hosts use a "defense in-depth strategy," with successive flexible lines of defense that coevolve with corresponding offensive lines of the parasite. This highlights the need for more holistic research into the coevolutionary consequences when multiple adaptations and counter-adaptations evolve in concert [11].

  3. Distress Calls of a Fast-Flying Bat (Molossus molossus Provoke Inspection Flights but Not Cooperative Mobbing.

    Directory of Open Access Journals (Sweden)

    Gerald Carter

    Full Text Available Many birds and mammals produce distress calls when captured. Bats often approach speakers playing conspecific distress calls, which has led to the hypothesis that bat distress calls promote cooperative mobbing. An alternative explanation is that approaching bats are selfishly assessing predation risk. Previous playback studies on bat distress calls involved species with highly maneuverable flight, capable of making close passes and tight circles around speakers, which can look like mobbing. We broadcast distress calls recorded from the velvety free-tailed bat, Molossus molossus, a fast-flying aerial-hawker with relatively poor maneuverability. Based on their flight behavior, we predicted that, in response to distress call playbacks, M. molossus would make individual passing inspection flights but would not approach in groups or approach within a meter of the distress call source. By recording responses via ultrasonic recording and infrared video, we found that M. molossus, and to a lesser extent Saccopteryx bilineata, made more flight passes during distress call playbacks compared to noise. However, only the more maneuverable S. bilineata made close approaches to the speaker, and we found no evidence of mobbing in groups. Instead, our findings are consistent with the hypothesis that single bats approached distress calls simply to investigate the situation. These results suggest that approaches by bats to distress calls should not suffice as clear evidence for mobbing.

    2009-01-01

    This study investigates the relationships between the experience of mobbing at work and personality traits and symptom patterns as assessed by means of the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Participants were 107 workers who had contacted mental health services because they perceived themselves as victims of mobbing. In line with previous research, the results showed that the MMPI-2 mean profile was characterized by a neurotic component as evidenced by elevations of Scales 1, 2, and 3 and a paranoid component as indicated by elevation of Scale 6. Contrary to previous research, a pattern of positive and significant correlations was found between the frequency of exposure to mobbing behaviors and the MMPI-2 clinical, supplementary, and content scales, including the posttraumatic stress scale. Only about half the participants showed a severity of posttraumatic stress symptoms indicative of a posttraumatic stress disorder. The frequency of exposure to mobbing predicted suicidal ideation and behavior, with depression only partially mediating this relationship.

    As a category of bullying, mobbing is a form of violence in the workplace that damages the employing organization as well as the targeted employee. In Europe, the overall prevalence of mobbing in healthcare is estimated at 4%. However, few studies have explored mobbing among long-term care workers. This study aims to examine the frequency of mobbing in Swiss nursing homes and its relationships with care workers' (i.e. registered nurse, licensed practical nurse, assistant nurse, nurse aide) health status, job satisfaction, and intention to leave, and to explore the work environment as a contributing factor to mobbing. A cross-sectional, multi-center sub-study of the Swiss Nursing Homes Human Resource Project (SHURP). Nursing homes in Switzerland's three language regions. A total of 162 randomly selected nursing homes with 20 or more beds, including 5311 care workers with various educational levels. Controlling for facility and care worker characteristics, generalized estimation equations were used to assess the relationships between mobbing and care workers' health status, job satisfaction, and intention to leave as well as the association of work environment factors with mobbing. In Swiss nursing homes, 4.6% of surveyed care workers (n=242) reported mobbing experiences in the last 6 months. Compared to untargeted persons, those directly affected by mobbing had higher odds of health complaints (Odds Ratios (OR): 7.81, 95% CI 5.56-10.96) and intention to leave (OR: 5.12, 95% CI 3.81-6.88), and lower odds of high job satisfaction (OR: 0.19, 95% CI 0.14-0.26). Odds of mobbing occurrences increased with declining teamwork and safety climate (OR: 0.41, 95% CI 0.30-0.58), less supportive leadership (OR: 0.42, 95% CI 0.30-0.58), and higher perceived inadequacy of staffing resources (OR: 0.66, 95% CI 0.48-0.92). Mobbing experiences in Swiss nursing homes are relatively rare. Alongside teamwork and safety climate, risk factors are strongly associated with superiors

    Wu, H M; Hu, C J; Pai, K Y

    2009-01-01

    Blended elemental Cr-B and Mo-B powders in atomic ratio of 67:33, 50:50, and 20:80 were subjected to mechanical alloying up to 60 h and subsequent heat treatment to investigate effect of composition and heat treatment on the phase formation of Cr-B and Mo-B powders. It was studied by X-ray diffraction and differential thermal analysis. Mechanical alloying these powder mixtures for 60 h leads essentially to a amorphous structure except for the Mo 20 B 80 powder, which creates a partially amorphous MoB 4 structure. Annealing at lower temperatures relieves the strains cumulative in the milled powders and creates no new phase. The structures obtained after annealing the milled powders at higher temperature vary and depend on the overall composition of the powder mixtures. Annealing the milled Mo-B powders having greater Mo content ends up with a dissociation reaction at higher temperature.

    1992-01-01

    Electron microscopic study of single crystal of Mo-0.003 mas.% B alloy after zone melting and annealing at 2373 K was conducted to reveal the nature of planar defects and the role of boron in their formation. It was shown that planar defects should be considered as preprecipitations of MoB nonequilibrous phase out of molybdenum base solid solution. A planar defect was found to constitute a monolayer of boron atoms which consisted of B-B zigzag-like chains. Inturn the chains were surrounded by Mo atoms which formed hexagonal prism. The coherency of planar defects with matrix was due to close lattice parameters of Mo, β-MoB and δ-MoB. The planar defects in molybdenum base alloy were considered as elements of dissipative structure. They determined formation of supercellular dislocation structure under deformation

    Members of the striatin family and their highly conserved interacting protein phocein/Mob3 are key components in the regulation of cell differentiation in multicellular eukaryotes. The striatin homologue PRO11 of the filamentous ascomycete Sordaria macrospora has a crucial role in fruiting body development. Here, we functionally characterized the phocein/Mob3 orthologue SmMOB3 of S. macrospora. We isolated the gene and showed that both, pro11 and Smmob3 are expressed during early and late developmental stages. Deletion of Smmob3 resulted in a sexually sterile strain, similar to the previously characterized pro11 mutant. Fusion assays revealed that ∆Smmob3 was unable to undergo self-fusion and fusion with the pro11 strain. The essential function of the SmMOB3 N-terminus containing the conserved mob domain was demonstrated by complementation analysis of the sterile S. macrospora ∆Smmob3 strain. Downregulation of either pro11 in ∆Smmob3, or Smmob3 in pro11 mutants by means of RNA interference (RNAi) resulted in synthetic sexual defects, demonstrating for the first time the importance of a putative PRO11/SmMOB3 complex in fruiting body development.

    Full Text Available Nowadays business life is getting even more complex. Although they were known previously, some subjects related to business life have been thought as spontaneous, have been neglected or have not been researched elaborately. However, in recent years, it can be observed that some of these subjects are being analyzed thoroughly more than before. Mobbing is one of these subjects which takes place rather frequently in either academic or other researches.Mobbing, which is among aggressive behaviour issue, should be evaluated both from the agressors’ and the victims’ point of view. In literature, it can be seen that there are numerous researches on mobbing which concentrates only on agressors, whereas there are not much studies examining mobbing victims. Therefore in the research part of this study mobbing victims are chosen as a sample and the relationship between mobbing victims and their personality characteristics is examined. The main assumption of the study is that some people who have specific personality characteristics are typically mobbing victims than others who do not have these personality characteristics.

    In this paper, we report integral and differential cross sections for the electronic excitation of H 2 molecules by electron-impact. Our scattering amplitudes were calculated using the Schwinger multichannel method within the minimal orbital basis for single configuration interactions (MOB-SCI) level of approximation. Through the use of the present strategy we have investigated the coupling effects among ground state and first singlet and triplet states of the same spatial symmetry. The five-state (nine for degenerated states) close-coupling calculations joined the advantages of a well-described set of physical states of interest with a minimum associated pseudo-state space. The results obtained by means of the MOB-SCI technique show a significant improvement towards experimental data in comparison with previous two-channel close-coupling calculations

    The influence of the organizational factors in mobbing onset, is supported by several studies. The leadership style is considered as one of its main antecedents. To investigate the relation between the leadership style adopted by the Nurse Coordinator and the diffusion of "negative actions", main indicator and antecedent of mobbing onset. Empirical study that involved 175 nurses and obstetricians of a Public Hospital Corporation in North Italy. Data has been collected via a semi-structured and anonymous questionnaire. The results confirm the hypothesis that the adoption of a non-collaborative leadership style goes with a greater diffusion of "negative actions" among the nurses. To intervene on organizational variables, such as the leadership style, allows to reduce the working unease and, therefore, the factors which are linked to it and which bear on the provided relief quality. The results of this study underline the Nurse Coordinator role in preventing and thwarting the onset of "negative actions", which are a potential source for mobbing onset.

    DC magnetron sputtering was used to deposit molybdenum boride thin films for potential low-friction applications. The films exhibit a nanocomposite structure with ∼10 nm large MoB 2−x (x > 0.4) grains surrounded by a boron-rich tissue phase. The preferred formation of the metastable and substoichiometric hP3-MoB 2 structure (AlB 2 -type) is explained with kinetic constraints to form the thermodynamically stable hR18-MoB 2 phase with a very complex crystal structure. Nanoindentation revealed a relatively high hardness of (29 ± 2) GPa, which is higher than bulk samples. The high hardness can be explained by a hardening effect associated with the nanocomposite microstructure where the surrounding tissue phase restricts dislocation movement. A tribological study confirmed a significant formation of a tribofilm consisting of molybdenum oxide and boron oxide, however, without any lubricating effects at room temperature.

In current study sample of 500 was taken to assess the consumer’s buying decision satisfaction in relation to the importance of their values associated with those decisions. This study also reveals how gender influences buying decision satisfaction. Consumer values have a positive and significant impact on buying decision satisfac-tion. While evaluation on the basis of gender and females have more emotional and word of mouth linkages than males, on the contrary to this, males are more concerned with cultural val-ues, and are less expressive and have a tendency to suppress their emotions while making buy-ing decisions.

    Full Text Available The business-life related competition established in modern communities has also brought about some other problems. The attacks and intimidation attempts have introduced the term of “mobbing” which is defined as regular and continuous psychological violence faced by people always trying to produce and win from those who they work with. The term of “mobbing” has recently become a popular academic issue which has been sophisticatedly handled in relevant literature. Mobbing is defined as the act of continuous and systematic intimidation purposefully performed by either some employees or employers on some employees through emotional violence. As mobbing is considered to be significant for both corporate and employee, the starting point of this study was to investigate how mobbing acts are reflected on newspapers as they are mass communication means. One of the most important means of media is print media. Print media is the first means of media when mentioned about media. Newspapers are means through which people are always kept up to date about the latest news in civilized societies. With this regard, the most basic purpose of this study is to investigate the news about the mobbing events experienced in higher education system under the light of national policy documents and reports. The study was carried out based on a qualitative approach. The news released in print media was chosen purposefully as print media means report news in a detailed way, have an evidential value and can be read again on demand. The research group in this study consists of the mobbing news released on Hurriyet, Sabah and Zaman which are newspapers published in Turkey between the years of 2009-2013. These newspapers were purposefully chosen based on criterion sampling method. The most basic understanding underlying this sampling method is to study on all cases which meet the standards set prior to the start of the study. The newspapers mentioned above were chosen

    Full Text Available The aim of the present study is to identify the psychosocial factors that are more related to the risk of workplace bullying in the organizational contexts. According to the work environment hypothesis, job demands, job control, perception of equity and leadership have been considered. It has been hypothesizedthat all these variables infl uence directly negative acts and also their effects are moderated by perception of colleagues. In order to investigate these relationships, a self-report questionnaire has been administered to 148 participants who represented all the population of a structure of private health care. The main results showed that job demands and leadership are the organizational antecedents more related to workplace bullying. Furthermore, the perception of colleagues has a moderating effect especially between job characteristics, like job demand, and negative acts, while this effect is weaker between relational antecedent, as leadership, and bullying. The data seem to confirm that mobbing prevention can be implemented starting from the psychosocial work environment and management of relationships involving leader and colleagues.

  9. Giant honeybees ( Apis dorsata) mob wasps away from the nest by directed visual patterns

    The open nesting behaviour of giant honeybees ( Apis dorsata) accounts for the evolution of a series of defence strategies to protect the colonies from predation. In particular, the concerted action of shimmering behaviour is known to effectively confuse and repel predators. In shimmering, bees on the nest surface flip their abdomens in a highly coordinated manner to generate Mexican wave-like patterns. The paper documents a further-going capacity of this kind of collective defence: the visual patterns of shimmering waves align regarding their directional characteristics with the projected flight manoeuvres of the wasps when preying in front of the bees' nest. The honeybees take here advantage of a threefold asymmetry intrinsic to the prey-predator interaction: (a) the visual patterns of shimmering turn faster than the wasps on their flight path, (b) they "follow" the wasps more persistently (up to 100 ms) than the wasps "follow" the shimmering patterns (up to 40 ms) and (c) the shimmering patterns align with the wasps' flight in all directions at the same strength, whereas the wasps have some preference for horizontal correspondence. The findings give evidence that shimmering honeybees utilize directional alignment to enforce their repelling power against preying wasps. This phenomenon can be identified as predator driving which is generally associated with mobbing behaviour (particularly known in selfish herds of vertebrate species), which is, until now, not reported in insects.

    The room temperature fracture toughness and the high temperature DBTT of MoB particle-reinforced MoSi 2 composites were investigated using Vickers indentation technique and MSP testing method, respectively. Modified small punch (MSP) test is a method for evaluation of mechanical properties using very small specimens, and it's appropriate for the determination of strength and DBTT. It was found that the approximate fracture toughness of the composite is 1.3 times that of monolithic MoSi 2 , and its DBTT is 100 C higher than that of monolithic MoSi 2 materials. Cracks deflection is a probable mechanism responsible for this behavior. (orig.)

    Many animals alter their anti-predator behavior in accordance to the threat level of a predator. While much research has examined variation in mobbing responses to different predators, few studies have investigated how anti-predator behavior is affected by changes in a predator's own state or behavior. We examined the effect of sparrowhawk ( Accipiter nisus ) behavior on the mobbing response of wild blue tits ( Cyanistes caeruleus ) using robotic taxidermy sparrowhawks. We manipulated whether the simulated predator moved its head, produced vocalizations, or held a taxidermy blue tit in its talons. When any sparrowhawk model was present, blue tits decreased foraging and increased anti-predator behavior and vocalizations. Additionally, each manipulation of the model predator's state (moving, vocalizing, or the presence of a dead conspecific) impacted different types of blue tit anti-predator behavior and vocalizations. These results indicate that different components of mobbing vary according to the specific state of a given predator-beyond its presence or absence-and suggest that each might play a different role in the overall mobbing response. Last, our results indicate that using more life-like predator stimuli-those featuring simple head movements and audio playback of vocalizations-changes how prey respond to the predator; these 'robo-raptor' models provide a powerful tool to provide increased realism in simulated predator encounters without sacrificing experimental control. Anti-predatory behavior is often modulated by the threat level posed by a particular predator. While much research has tested how different types of predators change prey behavior, few experiments have examined how predator behavior affects anti-predatory responses of prey. By experimentally manipulating robotic predators, we show that blue tits not only respond to the presence of a sparrowhawk, by decreasing feeding and increasing anti-predator behavior and vocalizations, but that they vary

    We examined victims' perceived responsibility and bystanders' anticipated risk of being victimized themselves when others associate them with the victim (stigma by association, SBA) as possible antecedents of bystanders' helping behaviour towards a victim of workplace mobbing, and explored the effects of gender. Guided by the attribution model of social conduct (Weiner, 2006), a 2 × 2 vignette experiment was conducted. Participants were Dutch regional government employees (N = 161). Path analyses generally supported the hypotheses, but showed different results for women and men. In the strong (Vs. weak) responsibility condition, women reported less sympathy and more anger and men only more anger, which resulted in lower helping intention. Additionally, for men the results showed an unexpected direct positive effect of responsibility on helping intention. Furthermore, in the strong SBA condition, women and men reported more fear and men, unexpectedly, more anger. Consequently, helping intention decreased. The findings on gender are discussed in the context of social role theory, gender and emotion. Our findings suggest that to prevent and tackle mobbing, organizations and professionals should be aware of the attributional and emotional processes and gender differences in bystanders' helping behaviour. © 2013 International Union of Psychological Science.

    Evidence in the literature suggests stress-related changes of hypothalamus-pituitary-adrenal (HPA) axis in mobbing. We investigated the association between HPA activity and psychological profiles in mobbing, using a multidisciplinary approach. Forty-eight victims of mobbing were evaluated by a working group of the Departments of Occupational Medicine, Psychiatry and Internal Medicine. After an informed consent, a detailed occupational history, a psychiatric interview with Minnesota Multiphasic Personality Inventory 2 (MMPI-2) administration and a blood sample (8:00 AM) for the determination of basal adrenocorticotropin (ACTH), cortisol and dehydroepiandrosterone sulphate (DHEAS) plasma levels were collected. Twenty-six patients received an overnight dexamethasone (dex) test. Mean ACTH, cortisol and DHEAS levels were within normal ranges. The dex-test response was normal, with a significant hormone suppression (ACTH pmobbing with adjustment disorders was observed. A larger group of patients is necessary to identify and validate a cut-off cortisol level that may become an innovative biological parameter for the diagnosis and follow-up in victims of mobbing.

    Full Text Available Among the crimes in the South African black townships, mob justice has become a growing concern. Some questions that need to be asked are: Is our police force doing enough to protect the ordinary citizens of this country? If the situation continues, will all suspects be killed in the same manner or will there be a solution to change the situation? What is the impact of mob justice on the families of the victims and the witnesses of the brutal acts? How long are we going to live as a traumatised nation as a result of these violent acts? Is there any hope that our nation will ever have the peace it deserves in the context of democracy? This article intends to investigate the impact of the mob justice system and find out what the role of the Christian church should be in the midst of this escalating violence. This study aims to unveil the negative impact of mob justice on the lives of many township South Africans and giving pastoral-biblical suggestions of the church’s role in the elimination of this kind of brutality.

    The concept of "work" and the social interactions in the workplace contribute to develop the working satisfaction and the social and personal identity of the adult. The aim of the survey is that of checking up on the presence of a statistically significant relation between The Depression Syndrome and The Mobbing Phenomenon. It is necessary to understand and value if and how some of the employer's behaviours could have a heavy influence on the worker's psychophysical condition, up to causing a state of anxiety and depression. It has been used the now famous "LIPT" (Leymann Inventory of Psychological Terror), elaborated by Leymann at the beginning of the 90's. It is a short anonymous questionnaire recognized all over Europe as a standard to confirm the Mobbing existence in organizational contexts. The current version of the questionnaire is called "LIPT EGE", a more suitable tool to check the seven parameters of the Mobbing determination, as well as the quantification of the consequent harm. Some scales for depressive symptoms evaluation have been added to the Mobbing questionnaire: The Self Rating Depression Scale (SDS) and The Depression Status Inventory (DSI) of Zung. The questionnaires are administered to 500 workers women in public and private corporation in Sicily, exactly in Siracusa and Catania provinces. 206 women aged 34-50 have answered the questionnaires. In addition to the age and the sex, the distinction variables of the examined people are the position in the firm, nationality, vocational qualification, and the yearly gross income. The research has begun in july and has continued on august 2006. Attention has been focused only on the administrative sectors. Through the chi2 test and the exact Fisher test, the dependence between the changeable presence of depression in the two questionnaires (Zung 1 and Zung 2) and every single variable of the questionnaire on the Mobbing has been pointed out. In particular, the results establish a connection between

    MoSi 2 -based intermetallics containing different volume fractions of MoB or Mo 5 Si 3 were fabricated by hot-pressing MoSi 2 , MoB, and Mo 5 Si 3 powders in vacuum. Both classes of alloys contained approximately 5 vol.% of dispersed silica phase. Additions of MoB or Mo 5 Si 3 caused the average grain size to decrease. The decrease in the grain size was typically accompanied by an increase in flexure strength, a decrease in the room temperature fracture toughness, and a decrease in the hot strength (compressive creep strength) measured around 1200 deg. C, except when the Mo 5 Si 3 effectively became the major phase. Oxidation measurements on the two classes of alloys were carried out in air. Both classes of alloys were protected from oxidation by an in-situ adherent scale that formed on exposure to high temperature. The scale, although not analyzed in detail, is commonly recognized in MoSi 2 containing materials as consisting mostly of SiO 2 . The MoB containing materials showed an increase in the scale thickness and the cyclic oxidation rate at 1400 deg. C when compared with pure MoSi 2 . However, in contrast with the pure MoSi 2 material, oxidation at 1400 deg. C began with a weight loss followed by a weight gain and the formation of the protective silica layer. The Mo 5 Si 3 containing materials experienced substantial initial weight losses followed by regions of small weight changes. Overall, the MoB and Mo 5 Si 3 additions to MoSi 2 tended to be detrimental for the mechanical and oxidative properties

  10. A degenerate primer MOB typing (DPMT method to classify gamma-proteobacterial plasmids in clinical and environmental settings.

    Full Text Available Transmissible plasmids are responsible for the spread of genetic determinants, such as antibiotic resistance or virulence traits, causing a large ecological and epidemiological impact. Transmissible plasmids, either conjugative or mobilizable, have in common the presence of a relaxase gene. Relaxases were previously classified in six protein families according to their phylogeny. Degenerate primers hybridizing to coding sequences of conserved amino acid motifs were designed to amplify related relaxase genes from γ-Proteobacterial plasmids. Specificity and sensitivity of a selected set of 19 primer pairs were first tested using a collection of 33 reference relaxases, representing the diversity of γ-Proteobacterial plasmids. The validated set was then applied to the analysis of two plasmid collections obtained from clinical isolates. The relaxase screening method, which we call "Degenerate Primer MOB Typing" or DPMT, detected not only most known Inc/Rep groups, but also a plethora of plasmids not previously assigned to any Inc group or Rep-type.

    A limitation of previous research on mobbing at work was that the individual consequences of the phenomenon were often assessed on 'clinical' samples of victims. Studies in organizations are less numerous and those available rarely evaluated the potential effect of mobbing over and above that of other psychosocial factors which provided robust evidence of adverse health effects. The relationship between exposure to mobbing and stress-related psychophysical conditions was investigated taking in consideration the possible concomitant exposure to job strain and effort-reward imbalance. Cross-sectional study on public administration administrative employees (No. = 538, 48% women). The psychosocial factors considered were assessed by means of well known and validated scales. The four health outcomes considered were psychological caseness (as operationalized by means of the general health questionnaire-12-item version), depression, gastritis and colitis/irritable colon syndrome as indicated by having reported a medical diagnosis of such conditions. Covariates: gender, age, body mass index, smoking habits and experience of a traumatic event in the last year. Analysis consisted of a series of logistic regressions. Exposure to mobbing was significantly associated with all the outcomes considered over and above the covariates. The inclusion in the models of job strain and effort-reward imbalance did not substantially alter the results. The relationship between mobbing at work and health outcomes is not confounded by concomitant exposure to job strain and effort-reward imbalance. These results offer further confirmation of the uniqueness of mobbing as a psychosocial risk factor.

    With extensive first-principles density-functional-theory calculations, we investigate the stability and the atomic and electronic structures of the CrB 2 (0001) and MoB 2 (0001) surfaces, each with two different terminations. It is found that the boron-terminated surface is energetically more favorable over the wide range of thermodynamically allowed chemical potentials than the metal-terminated surface for both CrB 2 (0001) and MoB 2 (0001), suggesting a stable layer of graphene-like boron on the surfaces. Our results also show the similarities and the differences in relaxation and in bonding characteristics between the boron-terminated and metal-terminated surfaces.

    2015-07-01

    Full Text Available Emotional abuse in the work place, psychological terror, social isolation, are terms well known to the Labor Union organizations. They all refer to harassment in the work place, which is actually mobbing. The word “mobbing” denotes a wide range of complex activities which represent harassment of the employees in their work places, in all social spheres. Therefore the consequences range from mild disturbances to disappointing repercussions to the employees. Those consequences mostly reflect badly on the family of the harassed employee, as well on the organization and the society in general. For that reason, the subject of this article is to analyze the regulations of the Law on Labor Relations which refer to protection of employees from harassment in the work place and to analyze the new “Law on Harassment Protection in the work place” adopted recently, in order to increase the protection measures against harassment in the work place on a higher level. The efficiency of this law is to be comprehended through professional and scientific approach, where the research should emphasize the efficiency of the new legal acts. The purpose of this article is not only to analyze the abovementioned laws on harassment protection in the work place in the Republic of Macedonia, but also to present a critique of the eventual mistakes that might occur during implementation and to identify legal gaps as obstacles against mobbing evidence. The methodological approach of this article is directed towards implementation of the qualitative methodanalyzing content founded on scientific and expert competence as well as on previously established real state of affairs by the adopted law regulations in order to present our own point of view. The conclusion of this article refers to the fact that weaknesses in some of the legal acts on the Law on Labor Relations and the Law on Harassment Protection could be noticed. Those cracks might be misinterpreted by the people

  17. Mobbing call experiment suggests the enhancement of forest bird movement by tree cover in urban landscapes across seasons

    Full Text Available Local scale movement behavior is an important basis to predict large-scale bird movements in heterogeneous landscapes. Here we conducted playback experiments using mobbing calls to estimate the probability that forest birds would cross a 50-m urban area during three seasons (breeding, dispersal, and wintering seasons with varying amounts of tree cover, building area, and electric wire density. We examined the responses of four forest resident species: Marsh Tit (Poecile palustris, Varied Tit (Sittiparus varius, Japanese Tit (P. minor, and Eurasian Nuthatch (Sitta europaea in central Hokkaido, northern Japan. We carried out and analyzed 250 playback experiments that attracted 618 individuals. Our results showed that tree cover increased the crossing probability of three species other than Varied Tit. Building area and electric wire density had no detectable effect on crossing probability for four species. Seasonal difference in the crossing probability was found only for Varied Tit, and the probability was the highest in the breeding season. These results suggest that the positive effect of tree cover on the crossing probability would be consistent across seasons. We therefore conclude that planting trees would be an effective way to promote forest bird movement within an urban landscape.

    Highlights: • We simulated a double stage 3D entrained flow coal gasifier with multi-opposite burners. • The various reaction mechanisms have evaluated with experimental results. • The effects of coal and oxygen distribution between two stages on the performance of gasifier have investigated. • The local coal to oxygen ratio is affecting the overall efficiency of gasifier. - Abstract: A 3D CFD model for two-stage entrained flow dry feed coal gasifier with multi opposite burners (MOB) has been developed in this paper. At each stage two opposite nozzles are impinging whereas the two other opposite nozzles are slightly tangential. Various numerical simulations were carried out in standard CFD software to investigate the impacts of coal and oxidant distributions between the two stages of the gasifier. Chemical process was described by Finite Rate/Eddy Dissipation model. Heterogeneous and homogeneous reactions were defined using the published kinetic data and realizable k–ε turbulent model was used to solve the turbulence equations. Gas–solid interaction was defined by Euler–Lagrangian frame work. Different reaction mechanism were investigated first for the validation of the model from published experimental results. Then further investigations were made through the validated model for important parameters like species concentrations in syngas, char conversion, maximum inside temperature and syngas exit temperature. The analysis of the results from various simulated cases shows that coal/oxidant distribution between the stages has great influence on the overall performance of gasifier. The maximum char conversion was found 99.79% with coal 60% and oxygen 50% of upper level of injection. The minimum char conversion was observed 95.45% at 30% coal with 40% oxygen at same level. In general with oxygen and coal above or equal to 50% of total at upper injection level has shown an optimized performance

Aplicaram-se carbonato de cálcio, sulfato de cálcio ou a mistura das duas fontes de cálcio às amostras superficiais, as quais foram colocadas a incubar e depois submetidas a sete aplicações de água destilada, na taxa de 1 volume-poro por semana, durante sete semanas consecutivas. O lixiviado foi recolhido semanalmente e analisado para cálcio, magnésio, potássio e sulfato solúveis. Nos solos, fizeram-se determinações dos teores de cálcio, magnésio e potássio trocáveis, e a determinação da acidez potencial a pH 7,0. A aplicação de sulfato de cálcio favoreceu o processo de lixiviação de potássio e magnésio, enquanto que a aplicação de carbonato de cálcio minimizou a lixiviação. Concluiu-se que a utilização de sulfato de cálcio para a correção da deficiência de cálcio em subsolos ácidos deve ser acompanhada necessariamente da aplicação de carbonato.

    Youth, as future citizens, play an important role in obtaining and maintaining water resources. Water EducaTion for Alabama's Black Belt (WET Alabama) provides off-campus environmental and water-education activities designed to increase the appreciation, knowledge, conservation, and protection of water resources by middle-school teachers and children from predominantly African-American families in some of Alabama's poorest counties. The project is structured around a variety of indoor and outdoor activities held at two field sites, Auburn University's E. V. Smith Center in Macon County and the Robert G. Wehle Nature Center in Bullock County located in Alabama's "Black Belt" region, a region in which the prosperity of local communities is low. The educational activities provide an engaging laboratory and field experience for children from rural schools that lack scientific facilities and equipment. Both hosting centers have easy access to surface water (ponds, wetlands, streams) and offer facilities for basic hydrologic experiments (e.g., aquifer models, permeameter, water quality). The E.V. Smith site has access to groundwater through pairs of nested wells. Educational activities are designed to help students and teachers visualize groundwater flow and its interaction with surface water in an aquifer tank model; compare the hydrologic properties (porosity and permeability) of different aquifer materials (sands, gravels, and clays); learn about groundwater purging and sampling; and assess water quality and flow direction in the field. Simple exercises demonstrate (1) the balance of recharge and discharge, (2) the effects of flooding, drought and pumping, and (3) movement of contaminants through aquifers. A set of ready-to-teach laboratory exercises and tutorials address goals specified by the State of Alabama science curriculum for grades 6 to 8. The ultimate goal of Project WET Alabama is to help students and teachers from resource-poor schools become knowledgeable

    Full Text Available Este estudo analisou a concepção de operadores do Direito acerca do assédio moral no trabalho, sua avaliação nas instâncias jurídicas, o perfil dos trabalhadores vitimados atendidos, assim como o papel do Direito e da Psicologia em relação ao fenômeno. Foram realizadas entrevistas semiestruturadas junto a seis operadores do Direito. Com base na análise de conteúdo das entrevistas, constatou-se uma tendência, entre os entrevistados, de perceberem a natureza organizacional do fenômeno. O medo dos trabalhadores em denunciar eventos dessa natureza foi outro elemento apontado. Os participantes afirmaram ser muito difícil avaliar e comprovar o assédio nos casos que recorrem às diferentes instâncias jurídicas. Quanto ao papel da Psicologia, os entrevistados referem sua importância para a produção de conhecimento, avaliação psicológica dos casos e prevenção da violência psicológica nas organizações. Em relação ao papel do Direito, reiteraram que as instâncias legais sejam espaços de garantia de direitos e reparação de danos.This study analyses the concept of mobbing at work among operators of the Law. The assessment of this practice at legal institutions, the profile of workers affected, and the role of Law and Psychology toward this phenomenon are investigated. Six operators of the Law participated by semi-structured interviews. Based on content analysis of the interviews, it was observed a tendency to perceive the organizational nature of mobbing at work. Another element pointed by participants was the fearfulness of workers in reporting such kind of violence. The interviewed professionals also referred the hardness to assess mobbing in those cases that appeal to legal institutions. About the role of Psychology, they affirmed its importance to production of knowledge, psychological assessment of workers and prevention of psychological violence in organizations. Concerning the role of Law, they had reiterated that

    Full Text Available El objetivo de este artículo es analizar la prevalencia del mobbing y de otras formas de violencia en las organizaciones desde la metodología de evaluación y diagnóstico del mobbing utilizada en los estudios españoles Cisneros en los últimos años. Se analiza la prevalencia y las características del acoso psicológico en el trabajo a través del estudio más reciente de todos ellos: el estudio Cisneros VI. El estudio Cisneros VI es una encuesta sobre una muestra representativa de 4.250 trabajadores de todos los sectores de actividad de la comunidad de Madrid desarrollado en el marco de un convenio de investigación a iniciativa de la Consejería de Empleo y Mujer de la Comunidad de Madrid. Los resultados del estudio confirman que los sectores con más casos de mobbing son las administraciones públicas, las empresas que roveen de servicios sociales y personales a la comunidad, el sector sanitario y, en general las actividades del sector terciario. La intensidad del acoso sigue el mismo patrón por sectores. Algunas diferencias aparecen en la tasa de prevalencia del mobbing dependiendo de la etodología de evaluación del acoso según esta se haga con cargo a una definición de lo que es mobbing o con cargo a la existencia de conductas frecuentes de maltrato laboral. Se analiza el denominado problema del labelling y se propone una solución técnica de cara a la intervención y a la prevención del acoso en la organización. En cuanto a la violencia física o verbal directa referida por los trabajadores contra ellos, se observa que el sector sanitario, los servicios subcontratados a empresas y el sector educativo figuran a la cabeza. En el mobbing se señalan diferencias según la posición del trabajador en la organización, resultando más frecuentemente acosados los administrativos, y los mandos intermedios. Operarios y especialistas aparecen como los grupos que refieren más acoso anterior en los últimos cinco años. El grupo

    This study sought to understand prognostic implications of increased baseline left ventricular (LV) mass and geometric patterns in a high risk acute myocardial infarction. The LV hypertrophy and alterations in LV geometry are associated with an increased risk of adverse cardiovascular events. Quantitative echocardiographic analyses were performed at baseline in 603 patients from the VALIANT (VALsartan In Acute myocardial iNfarcTion) echocardiographic study. The left ventricular mass index (LVMi) and relative wall thickness (RWT) were calculated. Patients were classified into 4 mutually exclusive groups based on RWT and LVMi as follows: normal geometry (normal LVMi and normal RWT), concentric remodeling (normal LVMi and increased RWT), eccentric hypertrophy (increased LVMi and normal RWT), and concentric hypertrophy (increased LVMi and increased RWT). Cox proportional hazards models were used to evaluate the relationships among LVMi, RWT, LV geometry, and clinical outcomes. Mean LVMi and RWT were 98.8 +/- 28.4 g/m(2) and 0.38 +/- 0.08. The risk of death or the composite end point of death from cardiovascular causes, reinfarction, heart failure, stroke, or resuscitation after cardiac arrest was lowest for patients with normal geometry, and increased with concentric remodeling (hazard ratio [HR]: 3.0; 95% confidence interval [CI]: 1.9 to 4.9), eccentric hypertrophy (HR: 3.1; 95% CI: 1.9 to 4.8), and concentric hypertrophy (HR: 5.4; 95% CI: 3.4 to 8.5), after adjusting for baseline covariates. Also, baseline LVMi and RWT were associated with increased mortality and nonfatal cardiovascular outcomes (HR: 1.22 per 10 g/m(2) increase in LVMi; 95% CI: 1.20 to 1.30; p independent of LVMi. Increased baseline LV mass and abnormal LV geometry portend an increased risk for morbidity and mortality following high-risk myocardial infarction. Concentric LV hypertrophy carries the greatest risk of adverse cardiovascular events including death. Higher RWT was associated with an

    Abstract: We present a Semantically optiMize the dAta seRvice operaTion (SMART) system for better data discovery and access across the NASA data systems, Global Earth Observation System of Systems (GEOSS) Clearinghouse and Data.gov to facilitate scientists to select Earth observation data that fit better their needs in four aspects: 1. Integrating and interfacing the SMART system to include the functionality of a) semantic reasoning based on Jena, an open source semantic reasoning engine, b) semantic similarity calculation, c) recommendation based on spatiotemporal, semantic, and user workflow patterns, and d) ranking results based on similarity between search terms and data ontology. 2. Collaborating with data user communities to a) capture science data ontology and record relevant ontology triple stores, b) analyze and mine user search and download patterns, c) integrate SMART into metadata-centric discovery system for community-wide usage and feedback, and d) customizing data discovery, search and access user interface to include the ranked results, recommendation components, and semantic based navigations. 3. Laying the groundwork to interface the SMART system with other data search and discovery systems as an open source data search and discovery solution. The SMART systems leverages NASA, GEO, FGDC data discovery, search and access for the Earth science community by enabling scientists to readily discover and access data appropriate to their endeavors, increasing the efficiency of data exploration and decreasing the time that scientists must spend on searching, downloading, and processing the datasets most applicable to their research. By incorporating the SMART system, it is a likely aim that the time being devoted to discovering the most applicable dataset will be substantially reduced, thereby reducing the number of user inquiries and likewise reducing the time and resources expended by a data center in addressing user inquiries.

    and its connections to the workers' health. These changes render the work environment a hostile, inhumane place and, thus, qualitatively unbalanced with abrupt effects on the workers' mental health, since employe-es spend most of their lives developing interpersonal and social relations at work. Therefore, their quality of life is largely dependent on the quality of their work environment. It is in this environment, marked by quantitative performance and target-reaching pressures, and by the workers' depersonalization - treated as an object of production - that the socalled mobbing takes place, a process of extreme psychological violence against the worker that causes a series of psychological damages to them.

    Early experiments to study the effects of a solar eclipse on radio wave propagation were done with either a limited number of sites before any theory of the ionosphere had been confirmed or involved collecting data that proved to be unusable because submissions were missing critical information such as date, time or location. This study used the 2017 solar eclipse over the continental U.S. to conduct the first wide-area (across the U.S.) low-frequency (LF) propagation study. The data collection process was crowdsourced through the engagement of students/educators, citizens, ham radio enthusiasts, and the scientific community. In order to accomplish data collection by geographically dispersed citizen scientists, the EclipseMob team designed and shared a low cost, low tool/skill DIY receiver system to collect LF data that leveraged existing cell phone technology and made the experiment more accessible to students and people with no prior experience constructing electronic systems. To support engagement, in addition to web guides (eclipsemob..org), EclipseMob supplied 150 DIY kits and provided build/Q&A webinars and events. For the experiment, participants constructed a simple receiver system consisting of a homemade antenna, a simple homemade receiver to convert the radio frequency (RF) signals to audio frequencies, and a smart phone app. Before, during, and after the eclipse, participants used their receiver systems to record transmitter signal data from WWVB located near Fort Collins, Colorado on 60.000 kHz (a U.S. frequency standard that is operated by NIST and transmits time codes). A second frequency, 55.500 kHz transmitted by a LF station in Dixon, CA was also used. By using the time, date and location features of the smart phone, the problems experienced in earlier experiments could be minimized. By crowdsourcing the observation sites across the U.S., data from a number of different short, medium and long- paths could be obtained as the total eclipse crossed

    Full Text Available Les ombles chevaliers originaires du Léman se reproduisent à la fin de l'automne. En élevage, il est intéressant de retarder de quelques mois la période des ovulations car ce poisson a besoin d'une température inférieure à 6°C pendant l'ovulation. Il est plus facile de fournir une eau à cette température aux géniteurs retardés qui ovulent en hiver qu'à ceux qui ovulent naturellement en automne. Le conditionnement des ombles chevaliers en jours longs (17L-7N pendant l'automne permet de retarder de plusieurs mois la période des ovulations. Cette méthode a l'inconvénient de provoquer un étalement des ovulations sur plus de 3 mois. Le reconditionnement des géniteurs en jours courts en décembre supprime ce problème. L'efficacité du traitement en jours longs ne semble pas dépendre de la durée de son application pourvu que celle-ci dépasse 1,5 mois. Chez les femelles conditionnées en jours longs en automne et en hiver, les concentrations en gonadotropine plasmatique (GTH II sont très faibles. Le niveau de la GTH II plasmatique augmente trois semaines après un transfert en jours courts en janvier. Les concentrations de la GTH II plasmatique au cours de l'ovulation sont significativement plus faibles chez les femelles conditionnées en jours longs en janvier que chez les animaux reconditionnés en jours courts. A ce stade du cycle reproducteur, la GTH I plasmatique reste toujours à un niveau très faible, quel que soit le régime photopériodique. La pose d'implant de mélatonine chez les poissons ne modifie pas les sécrétions gonadotropes en jours longs comme en jours courts. La réceptivité hypophysaire des femelles à une stimulation de la sécrétion gonadotrope par une injection de GnRH n'est pas modifiée par le conditionnement des poissons en jours longs. Aucun effet du pimozide sur la sécrétion de la GTH II n'a pu être mis en évidence chez les géniteurs conditionnés en jours longs. Ces résultats permettent

Hence, 826 employees of public and private institutions in Ankara were included in the sample. The data obtained by a questionnaire that prepared by Leymann (1996’s MO scale, and Maslach (1981's BU scale and Haynes (1996's JS scale. Data was evaluated by using One-Way ANOVA, correlation, regression, and multiple regression SPSS. As can be seen from the results of research, applied and perceived MO has a significant impact on employees' JS’s levels and becomes effective in the creation of JS. On the other hand, BU syndrome were seen as a consequence of the resulting JS. These conditions affect each other and existence of one within the organizational structure, results emergence of the other two. Therefore, management of organization, all levels of managers, and employees as individuals should be aware of these psychological states and conduct studies aimed for its prevention.In this research, meaningful relationships have been identified in the mediating role of JS at the impact of MO on BU. On the other hand in terms of demographic variables, significant variations were found in the levels of MO, BU, and JS

These buffers are 3-[N-morpholino]propanesulfonic acid (MOPS), 4-[N-morpholino]butanesulfonic acid (MOBS) and 3-[N-morpholino]-2-hydroxypropanesulfonic acid (MOPSO). Enthalpies were obtained in water-methanol mixtures with methanol mole fraction (X m ) from 0 to 0.360. The first ionization enthalpy (ΔH 1 ) of all buffers was small (±1.2 kJ mol -1 ) at all solvent compositions. The second ionization enthalpy (ΔH 2 ) increased steadily with X m , rising from 20.7 to 25.6 kJ mol -1 for MOPS, 26.3-31.0 kJ mol -1 for MOBS and 23.5-32.2 kJ mol -1 for MOPSO. The results were compared to those for related biological buffers. The observed variations were interpreted in terms of solvent-solvent and solvent-solute interactions.

  3. Processing of Mo-Si-B intermetallics by extrusion and oxidation properties of the extruded Tl-MoSi2-MoB Systems

    Summers, Eric

    1999-01-01

    An extrusion process was developed that is able to consistently produce large quantities of Mo-Si-B rods without the presence of defects. Binder removal from the extruded rods was studied in detail and it was determined that heating rates on the order of 0.02degree/minute (1.2degree/hour) are necessary to remove the binder without the formation of defects. This low heating rate resulted in debinding times in excess of 70 hours (∼ 3 days). Wicking was investigated as a means to decrease the time necessary for binder removal. Using 0.05microm alumina powder as a wicking agent, binder removal times were reduced to 10 hours with heating rates up to 1degree/minute employed without defect formation. Once the extrusion process was complete the oxidation properties of the Tl-MoSi 2 -MoB extruded phase assemblage was investigated. It was determined that this composition exhibits catastrophic oxidation or pesting in the temperature range of 660--760 C, resulting in the material turning to dust. Outside of this temperature range the composition is oxidatively stable. Continuous mass measurements were taken at 1,300, 1,450, and 1,600 C to determine the oxidation rate constants of this material. Parabolic rate constants of 6.9 x 10 -3 , 1.3 x 10 -3 , and 9.1 x 10 -3 mg 2 /cm 4 /hr were determined for 1,300, 1,450, and 1,600 C respectively

    Capillary refill time (CRT) is a clinical test used to evaluate the circulatory status of patients; various methods are available to assess CRT. Conventional clinical research often demands large numbers of patients, making it costly, labor-intensive, and time-consuming. We studied the interobserver agreement on CRT in a nationwide study by using a novel method of research called flash mob research (FMR). Physicians in the Netherlands were recruited by using word-of-mouth referrals, conventional media, and social media to participate in a nationwide, single-day, "nine-to-five," multicenter, cross-sectional, observational study to evaluate CRT. Patients aged ≥ 18 years presenting to the ED or who were hospitalized were eligible for inclusion. CRT was measured independently (by two investigators) at the patient's sternum and distal phalanx after application of pressure for 5 s (5s) and 15 s (15s). On October 29, 2014, a total of 458 investigators in 38 Dutch hospitals enrolled 1,734 patients. The mean CRT measured at the distal phalanx were 2.3 s (5s, SD 1.1) and 2.4 s (15s, SD 1.3). The mean CRT measured at the sternum was 2.6 s (5s, SD 1.1) and 2.7 s (15s, SD 1.1). Interobserver agreement was higher for the distal phalanx (κ value, 0.40) than for the sternum (κ value, 0.30). Interobserver agreement on CRT is, at best, moderate. CRT measured at the distal phalanx yielded higher interobserver agreement compared with sternal CRT measurements. FMR proved a valuable instrument to investigate a relatively simple clinical question in an inexpensive, quick, and reliable manner. Copyright © 2016 American College of Chest Physicians.

    The aim of this study is to produce preliminary data about the validation of the "Naples-Questionnaire of Distress at Work" (nQ.DW). This inventory is a new assessment tool in order to evaluate the distress perceived in the working environment by means of the differentiation of the conditions linked to the mobbing from which related to organizational disfunction. The nQ-DW also measures the bio-psycho-social global effects of these two phenomena. The questionnaire has been administered to workers suffering of a psychopathological disturbance related to work distress and to a control group matched for the sociodemographic and working variables. The statistical analysis demonstrated a significant validity and reliability. The degree of internal coherence was satisfactory. The ROC curves allow the determination of a threshold value which allows to separate the workers subjected to mobbing and/or organizational stress from control-workers with an optimal reliability degree. The values of the area under the ROC curves show that the inventory has a high discriminating capacity. Future studies, based on a greater sample size, will be oriented to the analysis of the questionnaire by means of multivariate techniques like the factorial analysis.

Utilizaram-se colunas de PVC, com 5cm de diâmetro e 45cm de altura, e aplicaram-se em cada coluna 1,8 litros de água, parcelados em quatro vezes. Determinaram-se os cátions trocáveis presentes na água percolada e, no final do experimento, em cinco profundidades de cada solo. Os resultados mostraram que nos tratamentos gesso e calcário mais gesso as quantidades de Ca2+, Mg2+, K+ e Al3+ na solução percolada foram maiores, enquanto que os tratamentos calcário agrícola e calcário calcinado não promoveram perdas significativas de cátions. As maiores perdas ocorreram na primeira percolação no solo de textura média e na segunda no solo de textura argilosa. O gesso não modificou o pH dos solos, mas reduziu teores de bases no solo argiloso, enquanto que os calcários corrigiram o solo apenas próximo à camada de incorporação.Soil columns under controlled conditions were used to determine the movement of calcium and other cations after the application of lime, calcium oxide, gypsum and a mixture of Ume and gypsum, compared with a control treatment.

The experiment was conducted in completely randomized design, with four treatments, consisting of four soils (electrical conductivity (EC 0.49 (control, 4.15, 6.33, 10.45 dS m-1 with four replications. Initially the plants were grown in rigid tubes, and 30 days after emergence, were transferred to pots containing 10 kg of soil, according to the salinity treatment. The parameters evaluated were plants height and dry matter and N, K, Ca, Mg and Na accumulation in shoots and roots. The salinity is detrimental to initial plant growth and cation accumulation in shoots and roots plants. Young moringa plants were not effective in inhibiting the absorption of Na and its translocation to the shoot.

    Spore heat resistance, germination, and outgrowth are problematic bacterial properties compromising food safety and quality. Large interstrain variation in these properties makes prediction and control of spore behavior challenging. High-level heat resistance and slow germination of spores of some natural Bacillus subtilis isolates, encountered in foods, have been attributed to the occurrence of the spoVA 2mob operon carried on the Tn 1546 transposon. In this study, we further investigate the correlation between the presence of this operon in high-level-heat-resistant spores and their germination efficiencies before and after exposure to various sublethal heat treatments (heat activation, or HA), which are known to significantly improve spore responses to nutrient germinants. We show that high-level-heat-resistant spores harboring spoVA 2mob required higher HA temperatures for efficient germination than spores lacking spoVA 2mob The optimal spore HA requirements additionally depended on the nutrients used to trigger germination, l-alanine (l-Ala), or a mixture of l-asparagine, d-glucose, d-fructose, and K + (AGFK). The distinct HA requirements of these two spore germination pathways are likely related to differences in properties of specific germinant receptors. Moreover, spores that germinated inefficiently in AGFK contained specific changes in sequences of the GerB and GerK germinant receptors, which are involved in this germination response. In contrast, no relation was found between transcription levels of main germination genes and spore germination phenotypes. The findings presented in this study have great implications for practices in the food industry, where heat treatments are commonly used to inactivate pathogenic and spoilage microbes, including bacterial spore formers. IMPORTANCE This study describes a strong variation in spore germination capacities and requirements for a heat activation treatment, i.e., an exposure to sublethal heat that increases

    Deadly Liver Mob (DLM) is a peer-driven, incentivised health promotion program aimed at increasing understanding of hepatitis C, promoting harm reduction in relation to injecting drug use, and linking participants to screening for hepatitis C, other blood borne viruses and sexually transmissible infections among Aboriginal people in Western Sydney, NSW. This paper presents the evaluation of a pilot study examining the acceptability of the program as a first step of a scalability assessment. Deadly Liver Mob operated in co-located needle and syringe programs and sexual health clinics in two sites: (Site 1: two and a half years for 2 days/week; Site 2: 1 year for 1 day per week). Comparisons were made of the proportion of Aboriginal clients (Site 1) and occasions of service provided to Aboriginal clients (Site 2) in the 12 months prior and post-introduction of DLM. Interviews were conducted with 13 staff involved in delivery of DLM and with 19 clients. A total of 655 and 55 Aboriginal clients, respectively, attended Site 1 and Site 2 for health education. The proportion of Aboriginal clients attending both sites was significantly higher during the DLM compared with prior to its implementation. Of those attending for health education, 79 and 73%, respectively, attended screening following education. DLM clients strongly endorsed the program. Some staff were concerned about workforce capacity to effectively engage Aboriginal clients with multiple and complex needs, managing the differing aims of the participating services involved, and about offering of incentives for attendance at health services. While acceptability was high among staff and clients and preliminary results show high engagement with Aboriginal communities, this evaluation of a pilot program raises some issues to consider in scale up of DLM to other sites. The initiation of additional DLM sites should address issues of alignment with governing strategies and workforce capacity.

    It is a general impression in the world of medicine that orthopaedic surgeons differ from doctors of other specialities in terms of intellect and self-confidence. The purpose of this study was to evaluate the self-confidence of orthopaedics. We asked doctors from 30 different specialities to fill out a questionnaire. In addition to this, the participating orthopaedics were asked to rate their self-perceived surgical skills. In all, 120 orthopaedics and 416 non-orthopaedic doctors completed the questionnaire. There was no difference in GSE scores between orthopaedics and other doctors (p = 0.58). 98% of young orthopaedics estimated that their surgical talent was average or above average when compared with their colleagues on the same level of education. 72% believed that they were "equally talented", "more talented", or "far more talented" than their colleagues on a higher level of education. 76% believed that when assisting a senior surgeon the patients would "sometimes" (60%), "often" (14%) or "always" (2%) be better off if they were the ones performing the operation. More orthopaedics than non-orthopaedics believed that their speciality was regarded as one of the least important specialities in the world of medicine (p = 0.001). Orthopaedic surgeons in general are not more self-confident than other doctors or the average population, but young orthopaedic surgeons have a very high level of confidence in their own operation skills. none. none.

    Full Text Available Os processos fisiológicos das plantas são afetados pelo balanço de cátions e ânions absorvidos. O objetivo deste trabalho foi determinar a absorção de cátions e ânions quando plantas de capim-coastcross receberam doses elevadas de nitrogênio. O delineamento experimental foi o de blocos casualizados com quatro repetições, num esquema fatorial 2x5 - duas fontes de N: uréia e nitrato de amônio, e cinco doses de N: 0, 25, 50, 100, 200 kg ha-1 corte-1 . As doses de N foram aplicadas após cada corte num total de cinco cortes, durante a época das chuvas. A absorção de cátions e de ânions pelo capim-coastcross aumentou com o acréscimo das doses de N dos dois fertilizantes, sendo maior com o nitrato de amônio. Com doses crescentes de N, verificou-se entre os cátions maior absorção do K+, e do Cl- entre os ânions. Com exceção do N, a absorção do K+ foi superior à dos demais nutrientes, com redução no teor relativo de cálcio. Doses altas de N aplicadas em capim-coastcross, na forma de uréia ou de nitrato de amônio, favorecem a absorção de cátions e de ânions.Physiologic processes of plants are affected by uptake of cations and anions. The aim of this work was to determine the uptake of cations and anions when plants of coastcross grass received high doses of nitrogen. The experimental design was a randomized block, in a 2x5 factorial arrangement - two N sources: urea and ammonium nitrate and five N rates: 0, 25, 50, 100, and 200 kg ha-1 cutting-1 - with four replications. Treatments were applied after each of five consecutive cutting in the rainy season. Uptake of cations and anions by coastcross grass increased with increasing of N rates with both fertilizers, but was higher with ammonium nitrate. Increasing rates of N caused higher K+ uptake in relation to other cations, and in Cl- among the anions. Except for N, K+ uptake was greater than that of other nutrients, with a reduction on the relative content of Ca2

    In Uganda, before the acquired immunodeficiency syndrome (AIDS) epidemic, rape or sexual abuse of children was not considered a serious offense by the public, although the maximum criminal offense for rape was death. Because so many young girls are testing positive for human immunodeficiency virus (HIV), and due to the efforts of women's groups, public opinion is changing. According to the United Nations International Children's Fund (UNICEF), girls aged 9-15 years are five times more likely to be infected with HIV than boys of the same age. Adults, who fear their peers may be infected with HIV, turn to children; some AIDS patients believe sleeping with a virgin girl will cure their illness. Uganda is targeting a $15 million project to protect children 5-15 years of age. A study commissioned by the Uganda National Council for Women and Children in 1994 found that in Kabale district 31% of girls and 15% of boys had been abused, many by teachers. In Masaka district, the Council found that 30% of women had been coerced into sex; bosses abuse their maids, and customers abuse alcohol sellers. According to police, rape is the second most common crime in Uganda. Victims are reluctant to come forward to testify; rape victims can be shunned in their communities and may be considered ineligible for marriage. Cases which make it to court rarely get a fair hearing, according to the Council of Women, because the men handling the cases often favor the culprits. FIDA, an association of women lawyers, Action for Development (ACFODE), and the National Association of Women's Organisations in Uganda (NAWOU) are lobbying for tougher laws on rape and closed courts. They are pressuring newspapers to not disclose the names of victims. Although many expect the Ministry of Women to take the lead in this area, it has been unable to do so, because of a lack of funds; it received two-thirds of its budget for 1994-95, an indication, perhaps, of the Ugandan government's intentions. Two figures are shown; one concerns the relation of abuser to child, while the other concerns the action taken on abuse cases.

    An experiment to measure ΔσL and ΔσT for pion production in pp scattering is in preparation at the Indiana Cooler. Both, pparrowppπ^circ and pparrowpnπ^+ reactions, will be studied. Either two charged particles or the neutron and the proton are detected in the exit channel. The experiment requires the acceleration of longitudinally polarized stored protons. Recently, longitudinally polarized beam has been successfully stored and accelerated to 400 MeV. The experiment uses the Wisconsin/IUCF polarized storage cell target. Upgrades to the experimental setup which has been used previously for a measurement of spin correlation parameters in pp elastic scattering will be discussed. The detector response is studied by means of a Monte Carlo simulation. Expected performance parameters will be presented.

No entanto, não se sabe se os teores desses compostos nos resíduos das culturas podem ser modificados pela aplicação de calcário e gesso em superfície. O presente trabalho objetivou avaliar os efeitos das aplicações de calcário e gesso em superfície sobre os teores de cátions solúveis nos resíduos vegetais das culturas de arroz, feijão e aveia-preta. O experimento foi realizado em um Latossolo Vermelho distroférrico de Botucatu (SP. O delineamento foi de blocos casualizados com parcelas subdivididas e quatro repetições. As parcelas foram constituídas por quatro doses de calcário dolomítico (0, 1.100, 2.700 e 4.300 kg ha-1 e as subparcelas, pela aplicação ou não de 2.100 kg ha-1 de gesso agrícola. Para as culturas de verão foi utilizado esquema de parcela subsubdividida. As subsubparcelas foram constituídas por dois cultivares de arroz de terras altas (Caiapó e IAC 202, no ano agrícola 2002/03, e dois cultivares de feijão (Pérola e Carioca, em 2003/04. A aveia-preta foi cultivada no inverno dos dois anos, utilizando apenas o cultivar Comum. Os teores de cátions solúveis na parte aérea das culturas de arroz, feijão e aveia-preta foram alterados pela aplicação de calcário e gesso em superfície. A gessagem em superfície aumentou os teores solúveis de Ca e reduziu o de Mg na parte aérea das culturas, principalmente nas primeiras safras após a aplicação. A calagem aumentou os teores de cátions solúveis na parte aérea de todas as culturas. As culturas do feijão e da aveia-preta apresentaram maiores teores de cátions solúveis nos resíduos da parte aérea, avaliados no florescimento.Surface liming efficiency can be increased through water-soluble organic compounds released by plant residues.

The experiment consisted in a completely randomized block design with four treatments. Calcium chloride and sodium bicarbonate were added to DCAB manipulations to achieve the values: -12; + 30; +76 and +133mEq/kg DM. There was no effect of DCAB (P>0.10 on fecal and urinary pH, and on phosphorus and magnesium balance. The increase in the DCAB corresponded to a decrease in calcium absorption and calcium retention, and an increase in calcium fecal excretion values. The manipulation of the DCAB affected the macromineral metabolism, mainly the calcium metabolism.

    Full Text Available O uso da água para a irrigação do arroz no Rio Grande do Sul, cujos mananciais hídricos têm ligação com o mar, pode ocasionar acúmulo de sais no solo em concentrações prejudiciais ao estabelecimento da cultura nos anos subsequentes, especialmente quando são aplicadas altas doses de fertilizante potássico na linha de semeadura. Este trabalho foi realizado com o objetivo de avaliar o efeito do manejo da adubação potássica sobre o estabelecimento e a absorção de cátions pelo arroz (cultivar IRGA 417 em um solo com diferentes níveis de saturação por Na. Foram utilizados um Planossolo Háplico com saturações por Na na troca de 5, 10 e 20 %; três manejos da adubação com cloreto de K equivalentes a 120 kg ha-1 de K2O a lanço; 120 kg ha-1 de K2O na linha de semeadura e 60 kg ha-1 de K2O na linha de semeadura, além de uma testemunha, sem adição de sal e de fertilizante, fatorial (3 x 3 + 1. O estande de plântulas não foi afetado pelos níveis de salinidade do solo e manejo da adubação potássica. A ontogenia da planta foi afetada pela salinidade, com atraso na emergência das plântulas. A salinidade do solo, a partir de 10 % de saturação por Na no complexo de troca, inibiu a absorção de K e reduziu o crescimento das plântulas de arroz, assim como diminuiu as relações K/Na, Ca/Na e Mg/Na no tecido. A interação entre manejo da adubação x salinidade reduziu o teor de Ca trocável no solo, aumentou o teor de Na na parte aérea e reduziu a relação Ca/Na na parte aérea do arroz.The use of water for rice irrigation in Rio Grande do Sul, Brazil, where the water courses are connected with the sea, may cause salt accumulation in the soil at harmful levels for the establishment of rice plants in the following years, especially when high rates of potassium fertilizer are applied in the plant rows.

    Full Text Available A menor reatividade do calcário abaixo dos locais de aplicação deve-se principalmente à sua baixa solubilidade, ao aumento das cargas negativas nas camadas aplicadas devido ao aumento do pH e à pequena permanência dos ânions adicionados na solução do solo. O presente trabalho teve por objetivo avaliar o efeito da adição de ânions a partir de sais de K sobre a superfície do solo, no incremento da reatividade do calcário e na mobilidade de seus cátions em um Cambissolo Húmico. O experimento foi realizado em 2005, em solo com 360 g kg-1 de argila, 60 g kg-1 de matéria orgânica e pH 4,1. Foram utilizadas três doses de calcário dolomítico (0, 0,74 e 1,48 kg m-2, combinadas com 40 g m-2 de K, na forma de KCl ou de KNO3, e com uma testemunha sem K, todos incorporados no primeiro centímetro da coluna do solo. As unidades experimentais (colunas de PVC com 10 x 30 cm, contendo 1,5 kg de solo foram percoladas 21 vezes, a cada sete dias, com 300 mL de água destilada por semana, totalizando o equivalente a 800 mm de chuva. Os sais potássicos lixiviaram muito mais Ca e Mg do que o calcário. Na média dos três tratamentos de calagem, a adição dos sais aumentou a lixiviação total de Ca, Mg e K, respectivamente de 36 para 132 mg, de 5,8 para 26 mg e de 25 para 51 mg/coluna, relativamente ao tratamento sem adição de sal. Na ausência dos sais, a aplicação da maior dose de calcário dolomítico lixiviou apenas 5 mg de Ca e 1,2 mg/coluna de Mg, em relação ao tratamento sem calcário. A calagem superficial afetou o pH do solo e a concentração de Ca, Mg e Al trocável até a profundidade máxima de 5,0 cm, cujas alterações foram quase sempre proporcionais à dose aplicada, porém não foram influenciadas pela adição dos sais. A aplicação dos fertilizantes potássicos não influenciou a capacidade reativa do calcário aplicado na superfície do solo.The low reactivity of lime below the application layer is mainly due to its

    Feature extraction for radiomics studies typically comprises the following stages: Imaging, segmentation, image processing, and feature extraction. Each of these stages has associated uncertainties that can affect the quality of a radiomics model created using the resulting image features. For example, the imaging device manufacturer and model have been shown to impact the values of image features, as have pixel size and imaging protocol parameters. Image processing, such as low-pass filtering to reduce noise, also changes calculated image features and should be designed to optimize the information content of the resulting features. The details of certain feature algorithms, such as co-occurrence matrix bin sizes, are also important, and should be optimized for specific radiomics tasks. The volume of the region of interest should be considered as image features can be related to volume and can give unanticipated results when the volumes are too small. In this session we will describe approaches to quantify the variabilities in radiomics studies, including the most recent results quantifying these variabilities for CT, MRI and PET imaging. We will discuss methods to optimize image processing and feature extraction in order to maximize the information content of the image features. Finally, we will describe work to harmonize imaging protocols and feature calculations to help minimize uncertainties in radiomics studies.

    The purpose of this study was to undertake an assessment and differentiated examination of the development of bullying and violence in schools between 2002 and 2010 in Germany.We examined the national German data of Health Behaviour in School-aged Children (HBSC) study in 2002, 2006 and 2010. A paper-pencil questionnaire was distributed to a representative sample (N=17 929) of 11-, 13- and 15-year-old school children. The evaluation of the data was done by descriptive statistics and logistic regression analyses, controlled by age, gender, family affluence, school type and survey year.A clear positive trend could be identified: from 2002 to 2010 the number of bullies and bully victims decreased whereas the group of the uninvolved pupils increased. There was a delay in this trend for children with low family affluence.The obvious success in the prevention of violence is shown by the decreasing rate of bullies. The paper discusses whether future prevention should focus more on victims and children with educationally deprived background. © Georg Thieme Verlag KG Stuttgart · New York.

    Based on pollen records in B-3GC gravity core, environmental change since 9500 aBP of Okinawa Trough and its adjacent islands was derived. The result showed that the most time during this period was in a warm temperate climate except in middle Holocene (6800-4400 aBP) that was under subtropical climate control. During 9500-8300 aBP and 3100-2000 aBP periods, it appeared colder and drier than the rest time. The original area of pollen sources surrounding Okinawa Trough was covered by evergreen and deciduous broadleaf forest alternatively with mixed broad-leaf-conifer forest distributed in high mountainous areas. Usually, these three kinds of forests existed at the same time with difference in altitude. Pollen from subtropical and tropical plants increased obviously in about 5000-6000 aBP, reflecting a great lifting of vegetation zone and expansion of evergreen broad-leaf forest in the study area. However, there was a slight descending of plant zone and shrinking of evergreen broadleaf forest during 9500-8300 aBP and 3000-2000 aBP. During the remaining periods vegetation zone was higher than the present but in a limited range.

    A combined theoretical and experimental study shows how weak attractive interactions of a neighbouring group can strongly promote chain walking and chain transfer. This accounts for the previously observed very different micro-structures obtained in ethylene polymerization by [κ2-N,O-{(2,6-(3\\',5\\'-R2C6H3)2C6H3-N=C(H)-(3,5-X,Y2-2-O-C6H2)}]NiCH3(pyridine)], namely hyperbranched oligomers for remote substituents R = CH3 versus. high molecular weight polyethylene for R = CF3. From a full mechanistic consideration the alkyl olefin complex with the growing chain cis to the salicylaldiminato oxygen donor is identified as the key species. Alternative to ethylene chain growth by insertion in this species, decoordination of the monomer to form a cis ß-agostic complex provides an entry into branching and chain transfer pathways. This release of monomer is promoted and made competitive by a weak η2-coordination of the distal aryl rings to the metal center, operative only for the case of sufficiently electron rich aryls. This concept for controlling chain walking is underlined by catalysts with other weakly coordinating furane and thio-phene motifs, which afford highly branched oligomers with > 120 branches per 1000 carbon atoms.

    Full Text Available УДК 242.9The subject. In the article the problems of creation and development of advanced development areas and free ports are analyzed. Territories with a special regime for the conduct of business are a phenomenon long known to the world. Classic examples: the island of Delos (Greece was declared a free trade zone, where merchants were exempt from taxes, duties and certain administrative duties. In Russia, the modern history of territories with a special regime for the implementation of entrepreneurial activity begins in the 1990s, when the first free economic zones were created: Vyborg, Dauria, Kuzbass, Nakhodka, Sadko, Sakhalin, TechnopolisZelenograd, Yantar, free trade zones or free customs zones Sheremetyevo, Moscow Franco-Port, Franco-Port Terminal. It is necessary to use the positive experience of foreign countries in this field.The purpose of this paper is to describe the problems of managing the territories of advanced development and free ports and to offer the government of the Russian Federation effective ways of solving these.Methodology. The author uses a dialectical method, a method of analysis and synthesis, a formal legal method, a comparative legal method.Results, scope. The author criticizes the Russian system of administration of the territories of advanced development and free ports of Vladivostok. The author points out that since each territory of advanced development and free ports of Vladivostok territory operate simultaneously on the territory of several municipalities, it is obvious that the highest exeutive authority of the subject of the Russian Federation, specifically the highest official of the subject of the Russian Federation in whose territory the сorresponding territory of advanced development. The author also proposes to extend the legal regime of the territories of advanced development and free ports to entities located in the territory of Western and Eastern Siberia. Effective organizational interaction between state and municipal authorities, the Management Company, the Supervisory and Public Councils with entrepreneurs and investors can only be ensured through the use of such a function of the authorities as coordination.Together, these measures will minimize the existing gap in the standard of living of the population and imbalance in the economic development of regions throughout Russia, and ultimately entail the accelerated economic development of the Russian Federation as a whole.The results of the study can be applied in the design of the legal regulation of creation and development of territories of advanced development and free ports.Conclusions. The author comes to the conclusion that the highest executive authority of the subject of the Russian Federation, specifically the highest official of the subject of the Russian Federation (the governor should become the coordinating center of administration of territory of advanced development and free ports of Vladivostok. This approach will improve the business and investment climate in all (and not in the selected constituent entities of the Russian Federation, create prerequisites for the development of their economic potential, will allow the subjects of the Russian Federation to make the most of their competitive advantages.

    Directory of Open Access Journals (Sweden)

    Andres Mauricio Hualpa Zuñiga

    2015-08-01

    Full Text Available This article contains the development of an algorithm applied to the solution of problems of sizing of storage spaces in companies in the construction sector. This problem is justified under the degree of informality that occurs at the time of assigning storage areas, without considering parameters related to stages of construction, the characteristics of the product and the provisions of the work area. In a previous study it is identified that the degree of informality at the moment of assigning storage areas, generates poor rates of capacity utilization and delivery of incomplete orders. The design of the algorithm is supported by a comprehensive model of sizing subjected to a system of equations with variables of quantity, volume and material dimensions, to finally establish the necessary storage area. The algorithm is adapted to programming language in order to present the results in graphic language where the sizing of storage spaces is visible. These results are validated through the evaluation of storage capacity utilization and completely delivered orders for different cargo units, where improvements in these indicators are shown.

    2014-04-01

    Full Text Available The article proposes a new interpretation of the iconic novel by Austrian writer Christoph Ransmayr, "The Last World" ("Die letzte Welt", 1988, recognized as the best European prose text of the late 1980s. The quest is the basis of the plot of the novel, the interpretation of Ovid’s mystified and mythologized poem, “Metamorphoses.” Various readings of the famous text can be interpreted as methods of externalization, verification of the author’s self-image, or attempts to approximate the truth of the primary meaning revealed in Genesis. The chosen foreshortening of the study reveals the forms of the author’s self-reflections through image-masks (hero—narrator—“com­mentator”—reader, a narrative story (facts of artistic reality—events of the story—the reading process—“commenting”, mystification of texts (works of world literature—character/narrator books—reader/“interpreter” texts, and a system of commentaries on them. Hero/storytellers, offer­ing different interpretations of the missing poem, implement their own understanding of reality, one that requires further discussion and examination. The process of cognition is the essence of reading; interpretations of prior texts and the creation of new ones disprove the main thesis of postmodernism about the reticence and hermeticity of works of literature. In this novel, Ovid reveals the mystery of elusive time, heaven, and hell. The process of empathy, the narrator’s and reader/listener’s co-creation, bring a closer understanding of the metaphysical foundations of being.

    Full Text Available The genus  Rubus L. is represented in southern Africa by the subgenera  Eubatus Focke and  Idaeobatus Focke. A combination o f morphological data, data on the reproductive systems of some collections and meiotic chromosome behaviour indicates that a hybrid swarm in the eastern Transvaal was formed subsequent to the hybridization between R. cuneifolius Pursh. taxon B (subgenus Eubatus and R. longepedicellatus (C. E. Gust. C. H. Stirton (subgenus Idaeobatus. Other examples of intra- and intersubgeneric hybridization were found during this study of the South African material. These instances, with examples found in the literature, indicate that the subgeneric subdivisions of Rubus are artificial. Three different methods were used to analyse the meiotic chromosome configurations. The genome relationship system of Alonso & Kimber (1981 and Kimber & Alonso (1981 and the modification of the binomial system of Jackson & Casey (1980 by Spies (1984 proved to be the most sensitive for distinguishing between alio-, segmental alio- and autoploids.

The implemented techniques comprise magnetron sputtering, ion irradiation, Rutherford backscattering spectrometry, Raman spectroscopy and spectroscopic ellipsometry. The capability of the cluster tool is demonstrated for a layer stack MgO/ amorphous Si (~60 nm)/ Ag (~30 nm), deposited at room temperature and crystallized with partial layer exchange by heating up to 650°C. Its initial and final composition, stacking order and structure were monitored in situ in real time and a reaction progress was defined as a function of time and temperature.

    1997-01-01

    consuming and tedious data preparation together with the complexity of network updating is the main reason for this, as most applied software packages can do the necessary calculations. In this paper we report on the development of a procedure that can automate the task of adding data for intersection delay...... modelling to an existing network. The method requires a GIS-based network with link attributes as input data. The method has developed as an extension tool applicable to existing networks and therefore supply of additional data is normally not required.. By a set of ‘expert system rules’, the intersections...... are classified in a number of groups - such as prioritised and signalised intersections, wedges and Y-junctions - and the required input data for turn delay models is established. The method has been tested on large-scale networks with good results. Most of the required data could be satisfactory estimated...

  5. Translation Strategy of Chinese Culture-loaded Lexes and the Dissemina-tion of Chinese Culture

    2016-01-01

    Lexes are the most important and basic element of a language. Chinese culture-loaded lexes are those words or expres-sions that are greatly rich in Chinese culture. They can reflect the characteristics of Chinese culture and Chinese nation. There-fore, it is of great significance to pay attention to the translation of Chinese culture-loaded lexes as they play a decisive role in disseminating Chinese culture. It can help promote Chinese culture worldwide, improve China’s cultural exchanges and commu-nication with other nations and strengthen China’s status in the world. This paper focuses on the Chinese culture-loaded words and proposes some possible means of translation with the purpose of spreading Chinese culture.

  14. ForgIng New paths in DIabetes PrevenTion (FINDIT): Study Protocol for a Randomized Controlled Trial.

    Kullgren, Jeffrey T; Youles, Bradley; Shetty, Shaina; Richardson, Caroline; Fagerlin, Angela; Heisler, Michele

    2017-04-08

    Prediabetes is an asymptomatic condition in which patients' blood glucose levels are higher than normal but do not meet diagnostic criteria for type 2 diabetes mellitus (T2DM). A key window of opportunity to increase engagement of patients with prediabetes in strategies to prevent T2DM is when they are screened for T2DM and found to have prediabetes, yet the effects of this screening and brief counseling are unknown. In this parallel-design randomized controlled trial we will recruit 315 non-diabetic patients from the Ann Arbor VA Medical Center (AAVA) who have one or major risk factors for T2DM and an upcoming primary care appointment at the AAVA, but have not had a hemoglobin A1c (HbA1c) test to screen for T2DM in the previous 12 months. After informed consent, participants will complete a baseline survey and be randomly assigned to, at the time of their next primary care appointment, one of two arms: (1) to have a hemoglobin A1c (HbA1c) test to screen for T2DM and receive brief, standardized counseling about these results or (2) to review a brochure about clinical preventive services. Participants will complete surveys 2 weeks, 3 months, and 12 months after their primary care appointment, and a weight measurement 12 months after their primary care appointment. The primary outcome is weight change after 12 months. The secondary outcomes are changes in perception of risk for T2DM; knowledge of T2DM prevention; self-efficacy and motivation to prevent T2DM; use of pharmacotherapy for T2DM prevention; physical activity; participation in weight management programs; and mental health. Quantitative analyses will compare outcomes among participants in the HbA1c test arm found to have prediabetes with participants in the brochure arm. Among participants in the HbA1c test arm found to have prediabetes we will conduct semi-structured interviews about their understanding of and reactions to receiving a prediabetes diagnosis. This trial will generate foundational data on the effects of a prediabetes diagnosis and brief counseling on patients' preventive behaviors and mediators of these behaviors that will enable the development of novel strategies to improve patient engagement in T2DM prevention.

  18. COULD MUSHROOMS ACT AS CONCENTRATION PATHWAYS TO INTERNAL CONTAMINA-TION OF SOME MARGINALIZED COMMUNITIES BY 137CS IN SLOVAKIA?

    Directory of Open Access Journals (Sweden)

    Juraj Miššík

    2015-02-01

    Full Text Available The aim of this study was to obtain some preliminary data necessary for the assessment of the possible existence of small-area local sources of contaminated mushrooms in forested areas with comparatively low inventory of man-made 137Cs. On the study plot near Čierne-Svrčinovec (North-western Slovakia 31 samples were collected during periodic sampling in the years 2012-2013 and analysed by gamma-spectrometry. Activities 137Cs in mushrooms from entire sampling plot followed the lognormal distribution with extremely high variation and high positive skew, with projected three-sigma (99.75% range from 0.49 Bq.kg-1 to 1537 Bq.kg-1 (dry weight, d.w. and with geometrical average of 27.4 Bq.kg-1 (d.w.. Another 11 samples were collected or bought from roadside vendors living in Roma slums near villages Richnava and Kluknava (Spiš region, eastern Slovakia. Obtained edible wild mushrooms were in a good shape despite prolonged drought indicating existence of well hidden forested sites in slum surroundings. Highest activity of 137Cs in this set was recorded in Boletus edulis (263.3 ± 20.3 Bq.kg-1 (d.w.. Both geometric mean (49.0 Bq.kg-1 and expectation value (91.2 Bq.kg-1 d.w. of lognormal distribution were higher than that of the study plot on NW Slovakia. No sample exceeded the legal radiohygienic limit for radiocesium contamination. The limited extent of presented study only slightly indicates the possibility of slow changes in spatial redistribution of bioavailable 137Cs in forest ecosystem. However, available data on this subject from different sources suggest that there is no reason for massive occurrence of highly contaminated fruiting bodies in small areas surrounding settlements, where some critical groups of individuals, who are used to consume large amounts of mushrooms from limited geographical area could in such case develop significant internal contamination.

  19. The integration of price/cost modelling and construction planning - the automated generation of construc­tion operation

    Directory of Open Access Journals (Sweden)

    P. A. Bowen

    1997-07-01

    Full Text Available The fact that traditional price/cost models are unrelated to the construction process renders them largely unsuited to the provision of meaningful price/cost advice. The nature and lengthiness of the construction planning process has precluded its incorporation into price/cost modelling during the pre-tender phase of the traditional building procurement process. The nub of the modelling problem has been how to integrate the complex process of construction planning into the pre-tender price/cost modelling process. In this paper the authors propose the synthesis of artificial intelligence techniques and construction planning techniques, resulting in a conceptual framework for a network-based cost modelling system for use by quantity surveyors in the cost modelling of buildings.

    Science.gov (United States)

    Liu, Yonghong; Gao, Chaochao; Lu, Yingying

    2017-04-01

    Urbanization directly drives rural to urban population migration and indirectly causes west to east migration in China, two phenomena that may significantly impact China's greenhouse gas emissions given its huge population and vast difference between the western rural and eastern urban areas. These two phenomena were analyzed by using emissions as a per capita term, and extending the impact from the traditional urbanization rate effect to include population density effect. The results show that population density has actually been the dominant demographic player in changing per capita emissions for the past two decades in China, and its elasticity changed from positive in economically less-developed provinces to negative for the developed provinces. This study provides a new perspective in the study of the relationship between urbanization and greenhouse gas emissions, and the results indicate that population density change should be taken into account to accurately assess the impact of urbanization.

  5. Spain, Reincarnated: Julio Medem’s Caótica Ana and New Spanish Media(tion in the World

    Directory of Open Access Journals (Sweden)

    Susan Martin-Márquez

    2009-06-01

    Full Text Available Spanish director Julio Medem’s visually stunning yet controversial 2007 film Chaotic Ana was panned for its ostensibly Manichaean treatment of gender relations and its crudely scatological ending, both of which have distracted attention from the work’s fascinating incursions into global politics. While the film’s complex layering of hawk and dove imagery figures centuries of male violence against women, it is also imbricated with an extended meditation on the divergent roles of the United States and Spain on the contemporary world stage. Through the male protagonist Said, a Saharawi painter, the film artfully shifts postcolonial guilt for the fate of the Western Sahara from the former colonizer Spain to the United States. Even as the film obfuscates Spain’s multifaceted imperial past, it engages in a withering indictment of U.S. foreign policy in the post-9/11 era, indicating through a web of symbolic references to the Statue of Liberty that Americans have turned away from their once-vaunted mission. That mission, the film (problematically suggests, must now be taken up by Spain, which, together with other enlightened European nations, serves as a beacon for global justice, drawing upon the Spanish National Court’s declaration of universal jurisdiction to prosecute the U.S. government’s neocolonial crimes against humanity.

    Full Text Available Instructing personnel in the issues of labor protection and industrial safety at hazardous facilities is one of the main tasks that face the employer; the quality with which this procedure is organized and carried out defines not only company’s indicators, but the mere possibility of its normal functioning. The paper contains a detailed overview of the typical content of standard documentation, which is currently used when conducting operations in the oil mines of Yarega high-viscosity oil deposit. Distinct features and unique nature of this oil field require special measures to guarantee safety of personnel and all facilities in general.The author proposes and reviews an additional type of operating guidelines – instructional map of safe working methods and practices. It is more illustrative than existing documentation (charts of inclined shaft development, labor protection regulations, which allows to upgrade the process of instructing personnel in the oil mines, to improve the quality of instructions and to reduce the risk of emergencies, accidents, industrial injuries.The author reviews the structure of suggested instructional map, offers a detailed arrangement diagram for the main thematic sections of the map, as well as their content. Instructional maps are regarded as a type of operating guidelines that include: description and characteristics of equipment, instruments and appliances; general safety requirements; content and execution sequence of operational elements with their graphical images; distribution of responsibilities with an indication of their priority in case the operations are conducted by several workers; specific safety requirements for equipment, materials, instruments, safety clothes and footwear, personal protective gear etc. (prohibitions, warnings.Advantages and disadvantages of proposed instructional maps of safe working methods and practices are highlighted.

    Directory of Open Access Journals (Sweden)

    Andreea DRAGHICI

    2013-09-01

    Full Text Available Organizations are often analyzed as open systems interdependent, interconnected or interrelated with the referential environment, where the resources, results, processes are evaluated as organizational environment, structure, dynamics and culture. „In a workplace environment that is built on a narrative that values staff needs for identity, belonging, and social interaction, workers are humanized. Cooperation, compassion, empathy, and mutual aid are engendered and employees work together to meet mutual goals, becoming allies rather than threats. Instead of viewing each other as competitors for scarce resources, organizational members are seen as collaborators; and differences in work styles and skills are valued, not feared. Thus, the context, in general and the organizational context, in particular, lays its prints on the development of individuals in a situational frame they perceive differently, choosing the terms of adaptation, costs and benefits, social rituals and beliefs, the set of values, norms and status, the best modality of dealing with the others, with their leaders, the preference for a certain type of management appealing to the personality of the people involved. In such organizational context the existence of conflicts within organizations generates bullying practices that has now become identified as a serious issue in the workplace context.

  12. Mobbing - et forsøk på nye teoretiske perspektiv

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This article discusses the understanding of bullying and how it first appears as a phenomenon in early childhood. Empirical research on the social life of young children indicates a capacity for empathy that is independent of social learning. Based upon Merleau-Ponty`s philosophy of the body and Levinas’s existentialist notion of the origin of morality, the article emphasize empathy and the sense of responsibility as a fundamental event in our initial encounter with one another – not learned competence based on cognitive refl ections. Anti-social behavior like bullying is therefore considered to be a narrowing of the initial openness for others entering our life-world, not a result of a natural urge to power and dominance.

    2014-01-01

    Medical physicists who were certified in 2002 or later, as well as those who become certified in the future, are enrolled in Maintenance of Certification. Many physicists with life-time certificates have voluntarily enrolled in MOC, as have physicists who volunteer their time to participate in the ABR exam development and administration processes. MOC consists of four components: Part 1, Professional standing; Part 2, Lifelong learning and self-assessment; Part 3, Cognitive expertise; and Part 4, Practice quality improvement. These four components together evaluate six competencies: Medical knowledge, patient care and procedural skills, interpersonal and communication skills, professionalism, practice-based learning and improvement, and systems-based practice. Parts 1, 2, and 3 of MOC are fairly straightforward, although many participants have questions about the process for attesting to professional standing, the opportunities for obtaining self-assessed continuing education, and the timing of the cognitive exam. MOC participants also have questions about Part 4, Practice Quality Improvement. PQI projects are powerful tools for improving the quality and safety of the environments in which we practice medical physics. In the current version of MOC known as “Continuous Certification” a medical physicist must have completed a PQI project within the previous three years, at the time of the ABR's annual look-back each March. For the first “full” annual look-back in March 2016, diplomates will be given an additional year, so that a PQI project completed in 2012, 2013, 2014, or 2015 will fulfill this requirement. Each component of MOC will be addressed, and the specifics of interest to medical physicists will be discussed. Learning Objectives: Understand the four components and six competencies evaluated by MOC. Become familiar with the annual requirements of Continuous Certification. Learn about opportunities for Practice Quality Improvement projects. Understand refinements occurring in the MOC program

    The motion management in stereotactic body radiation therapy (SBRT) is a key to success for a SBRT program, and still an on-going challenging task. A major factor is that moving structures behave differently than standing structures when examined by imaging modalities, and thus require special considerations and employments. Understanding the motion effects to these different imaging processes is a prerequisite for a decent motion management program. The commonly used motion control techniques to physically restrict tumor motion, if adopted correctly, effectively increase the conformity and accuracy of hypofractionated treatment. The effective application of such requires one to understand the mechanics of the application and the related physiology especially related to respiration. The image-guided radiation beam control, or tumor tracking, further realized the endeavor for precision-targeting. During tumor tracking, the respiratory motion is often constantly monitored by non-ionizing beam sources using the body surface as its surrogate. This then has to synchronize with the actual internal tumor motion. The latter is often accomplished by stereo X-ray imaging or similar techniques. With these advanced technologies, one may drastically reduce the treated volume and increase the clinicians’ confidence for a high fractional ablative radiation dose. However, the challenges in implementing the motion management may not be trivial and is dependent on each clinic case. This session of presentations is intended to provide an overview of the current techniques used in managing the tumor motion in SBRT, specifically for routine lung SBRT, proton based treatments, and newly-developed MR guided RT. Learning Objectives: Through this presentation, the audience will understand basic roles of commonly used imaging modalities for lung cancer studies; familiarize the major advantages and limitations of each discussed motion control methods; familiarize the major advantages and limitations of each discussed radiation beam control methodology and tumor tacking method; understand the key points in motion management for a high quality SBRT program.

    Oscillatory phenomena are ubiquitous in Nature. The ability of a large population of coupled oscillators to synchronize constitutes an important mechanism to express information and establish communication among members. To understand such phenomena, models and experimental realizations of globally coupled oscillators have proven to be invaluable in settings as varied as chemical, biological and physical systems. A variety of rich dynamical behavior has been uncovered, although usually in the context of a single state of synchronization or lack thereof. Through the experimental and numerical study of a large population of discrete chemical oscillators, here we report on the unexpected discovery of a new phenomenon revealing the existence of dynamically distinct synchronized states reflecting different degrees of communication. Specifically, we discover a novel large-amplitude super-synchronized state separated from the conventionally reported synchronized and quiescent states through an unusual sharp jump transition when sampling the strong coupling limit. Our results assume significance for further elucidating globally coherent phenomena, such as in neuropathologies, bacterial cell colonies, social systems and semiconductor lasers.

    Medical physicists who were certified in 2002 or later, as well as those who become certified in the future, are enrolled in Maintenance of Certification. Many physicists with life-time certificates have voluntarily enrolled in MOC, as have physicists who volunteer their time to participate in the ABR exam development and administration processes. MOC consists of four components: Part 1, Professional standing; Part 2, Lifelong learning and self-assessment; Part 3, Cognitive expertise; and Part 4, Practice quality improvement. These four components together evaluate six competencies: Medical knowledge, patient care and procedural skills, interpersonal and communication skills, professionalism, practice-based learning and improvement, and systems-based practice. Parts 1, 2, and 3 of MOC are fairly straightforward, although many participants have questions about the process for attesting to professional standing, the opportunities for obtaining self-assessed continuing education, and the timing of the cognitive exam. MOC participants also have questions about Part 4, Practice Quality Improvement. PQI projects are powerful tools for improving the quality and safety of the environments in which we practice medical physics. In the current version of MOC known as “Continuous Certification” a medical physicist must have completed a PQI project within the previous three years, at the time of the ABR's annual look-back each March. For the first “full” annual look-back in March 2016, diplomates will be given an additional year, so that a PQI project completed in 2012, 2013, 2014, or 2015 will fulfill this requirement. Each component of MOC will be addressed, and the specifics of interest to medical physicists will be discussed. Learning Objectives: Understand the four components and six competencies evaluated by MOC. Become familiar with the annual requirements of Continuous Certification. Learn about opportunities for Practice Quality Improvement projects. Understand refinements occurring in the MOC program.

    Full Text Available This article discusses the understanding of bullying and how it first appears as a phenomenon in early childhood. Empirical research on the social life of young children indicates a capacity for empathy that is independent of social learning. Based upon Merleau-Ponty`s philosophy of the body and Levinas’s existentialist notion of the origin of morality, the article emphasize empathy and the sense of responsibility as a fundamental event in our initial encounter with one another – not learned competence based on cognitive refl ections. Anti-social behavior like bullying is therefore considered to be a narrowing of the initial openness for others entering our life-world, not a result of a natural urge to power and dominance.

    Full Text Available The reduction of zeolite particle is one of the main features currently searched; it is due to the catalytic gains that these materials come in some reactions. In this work two faujasite zeolites of type X were evaluated, a micrometer and nanometric. Zeolites in sodium form were exchanged ionically with methylammonium cations. These materials were evaluated as catalysts in the Knoevenagel condensation reaction. Steric impediments restricted the ion exchange in the micrometer zeolite and have become more predominant due to the increase in the volume of cations. In nanometric sample such impediments were less evident due to the reduction of the particles provide greater accessibility to exchangers cations to inaccessible sodium in micrometer zeolite. The best catalytic performances were achieved with zeolites containing the monomethylammonium cation. The increased of the accessibility and diffusion of the reactants and products through the pores of the nanometric zeolite provided the best butyraldehyde conversions independent the exchanger cation

    Two consecutive years (4-crop) experiments were conducted to study the influence of different paddy rice-upland crop rotation in cold-waterlogged paddy field on the growth of crops and soil characteristics. The result showed that compared with the rice-winter fallow (CK) pattern, the two-year average yield of paddy rice under four rotation modes, including rape-rice (R-R), spring corn-rice (C-R), Chinese milk vetch-rice (M-R) and bean-rice (B-R), were increased by 5.3%-26.7%, with significant difference observed in C-R and R-R patterns. Except for M-R pattern, the annual average total economic benefits were improved by 79.0%-392.4% in all rotation pattern compared with the CK, and the ration of output/input was enhanced by 0.06-0.72 unit, with the most significant effect found in the C-R pattern. Likewise, compared with the CK, the contents of chlorophyll and carotenoid, and net photosynthetic rate (Pn) of rice plant were all increased during the full-tillering stage of rice in all rotation patterns. The rusty lines and rusty spots of soils were more obvious compared with the CK during the rice harvest, particularly in R-R, C-R and B-R patterns. The ratio of water-stable soil macro aggregates of plough layer of soil (> 2 mm) decreased at different levels in all rotation patterns while the ratios of middle aggregate (0.25-2 mm, expect for M-R) and micro aggregate of soil (< 0.25 mm) were opposite. There was a decreasing trend for soil active reducing agents in all rotation patterns, whereas the available nutrient increased. The amounts of soil bacteria in C-R and B-R patterns, fungi in B-R rotation pattern, cellulose bacteria in R-R, C-R and B-R patterns and N-fixing bacteria in B-R pattern were improved by 285.7%-403.0%, 221.7%, 64.6-92.2% and 162.2%, respectively. Moreover, the differences in all microorganisms were significant. Thus, based on the experimental results of cold-waterlogged paddy field, it was concluded that changing from single cropping rice system to C-R, R-R and B-R rotation patterns had good effect in terms of improving total yield and economic benefits, and soil physical and chemical properties were improved.

  7. Turning Subsistence Peasants into Ecosystem Servants: Inequality and the Produc-tion of Natural Resources in Lao P.D.R.

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available This paper examines the nexus of nature conservation, productivity and domination in inclusive conservation approaches. It argues that the turning of subsistence peasants into “stewards and custodians of biodiversity” (CBD represents a soft form of domination according to the false alternatives of ecological instrumentality in that local development is subordinated to supposed “natural” constraints. The argument draws from critical theories of societal nature relations (Horkheimer & Adorno, 2002; Görg. 2003; Moore, 2015 as well as from extensive research on ecotourism as an instrument to reconcile conservation and development in the Lao People’s Democratic Republic. From this angle, conservation is seen as a way to produce “natural” resources building on, perpetuating and creating various social inequities, based on the fiction that “nature” is essentially non-human. This case is made with regard to National Protected Areas in Laos, which are designed explicitly to accommodate local people’s needs. Among other things, ecotourism is employed to create a source of income alternative to practices seen as “unsustainable”. Thereby, economic and also moral stakes in untouched resources are to be implanted. In such way, a compromise between (rather than a reconciliation of conservation and development is imposed which is largely alien to the lived realities of local people, and only accounting partly for their needs and aspirations – an imposition which tends to produce its own countercurrents, again tying into productivity and inequality. This paper thus analyzes the workings of the nature/society dualism underlying ecological instrumentality as experienced in ecotourism as a tool for nature conservation in Laos.

    Background Heart failure with preserved ejection fraction (HFpEF) is the predominant form of HF among the elderly and in women. However, there are few if any evidence-based therapeutic options for HFpEF. The chief complaint of HFpEF is reduced tolerance to physical exertion. Recent data revealed that one potential mechanism of exertional intolerance in HFpEF patients is inadequate chronotropic response. Although there is considerable evidence demonstrating the benefits of rate-adaptive pacing (RAP) provided from implantable cardiac devices in patients with an impaired chronotropic response, the effect of RAP in HFpEF is unknown. Methods and Results The RESET study is a prospective, multi-center, double-blind, randomized with stratification, study assessing the effect of RAP on peak VO2 and quality of life. RAP therapy will be evaluated in a cross-over paired fashion for each patient within each study stratum. Study strata are based on patient beta-blocker usage at time of enrollment. The study is powered to assess the impact of pacing independently in both strata. Conclusions The RESET study seeks to evaluate the potential benefit of RAP in patients with symptomatic mild to moderate HFpEF and chronotropic impairment. Study enrollment began in July 2008.

    Some analytical experiences with NBS SRM 1569 Brewer's Yeast are presented. Against this background the adequacy of this standard reference material for the determination of chromium in biological materials is discussed. Authors have three main objections. Due to its high content of insoluble chromium-containing particles, SRM 1569 is not typical for biological materials, possibly not even for Brewer's Yeast. The chromium level of SRM 1569 is not typical for the chromium levels normally encountered in pure biological materials. The major fraction (69 +- 3 percent) of the chromium is present in a form which is insoluble under the conditions used in Author's analysis. (T.I.)

  11. Response of needle dark respiration of Pinus koraiensis and Pinus sylvestriformis to elevated CO2 concentra-tions for four growing seasons’ exposure

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The long-term effect of elevated CO2 concentrations on needle dark respiration of two coniferous spe- cies—Pinus koraiensis and Pinus sylvestriformis on the Changbai Mountain was investigated using open-top chambers. P. koraiensis and P. sylvestriformis were exposed to 700, 500 μmol·mol-1 CO2 and ambient CO2 (approx. 350 μmol·mol-1) for four growing seasons. Needle dark respiration was meas- ured during the second, third and fourth growing seasons’ exposure to elevated CO2. The results showed that needle dark respiration rate increased for P. koraiensis and P. sylvestriformis grown at elevated CO2 concentrations during the second growing season, could be attributed to the change of carbohydrate and/or nitrogen content of needles. Needle dark respiration of P. koraiensis was stimu- lated and that of P. sylvestriformis was inhibited by elevated CO2 concentrations during the third growing season. Different response of the two tree species to elevated CO2 mainly resulted from the difference in the growth rate. Elevated CO2 concentrations inhibited needle dark respiration of both P. koraiensis and P. sylvestriformis during the fourth growing season. There was consistent trend be- tween the short-term effect and the long-term effect of elevated CO2 on needle dark respiration in P. sylvestriformis during the third growing season by changing measurement CO2 concentrations. How- ever, the short-term effect was different from the long-term effect for P. koraiensis. Response of dark respiration of P. koraiensis and P. sylvestriformis to elevated CO2 concentrations was related to the treatment time of CO2 and the stage of growth and development of plant. The change of dark respiration for the two tree species was determined by the direct effect of CO2 and long-term acclimation. The prediction of the long-term response of needle dark respiration to elevated CO2 concentration based on the short-term response is in dispute.

    Full Text Available Soil organic matter (SOM undergoes short and long-term transformation in the soil. Microorganisms through their enzymes are able to mineralize organic carbon while the rate of this process is different. Biological test though referred to one of the main diagnostic methods for evaluating soil qualit­y/health. The aim of our work was to determine basal respiration, total carbon content, fractio­nal composition of humus and basic parameters of soil colloidal complex in selected subtypes of chernozem in South Moravia region. Basal respiration was measured using Vaisala GMT220 apparatus. Total carbon content was determined by oxidimetric titration and basic parameters of soil colloidal according to Mehlich. Results showed that production of carbon dioxide varied from 0.09 to 0.27 mg CO2/100g/h. Linear correlation between basal respiration and humification degree was found. Humus content varied from 2.15% to 4.6%. No correlation between quantity of humus and basal respiration was observed. Higher values of basal respiration were connected with higher quality of HS. Significant linear correlation between total carbon content (TOC and cation exchange capacity (CEC was found.

    The electrochemical behaviour of Zircaloy-4 electrode in chloride, bromide and iodide acid solution was investigated at 25 0 C employing stationary, quasi-stationary and potentiodynamic techniques. The results show that the pitting and repassivation potentials are independent on pH but both are dependent on halice concentration, following linear relation ships in these cases. It is also possible to correlate the pitting potential with the ionic radius of the anions, allowing thus to establish an order in their agressive properties. This order was extrapolated for fluoride ion and further experimental measurements show that the corrosion potential of Zircaloy-4 in acid or neutra solution of this ion (which undergoes active dissolution) is coincident with that predicted from the Ep v/s ionic radius determined for the other halides.

    2013-03-01

    Full Text Available Variability of the main morphometric features of imago flies Calliphora vicina R.-D. (Diptera, Calliphoridae of two samples was studied. First sample consists of individuals caught in the wild (park ecosystems of Dnipropetrovsk, the second one – specimens cultured in the laboratory under the constant temperature and humidity. Possible using of C. vicina R.-D. as a bioindicator of anthropogenic factors is analysed. Environmental factors may act as the stimulators of adaptive changes in physiological functions, as the constraints that cause impossibility of the existence of certain species in particular conditions, and as modifiers that determine the morpho- anatomical and physiological changes in organisms. The most significant differences between studied samples were found for the width (“laboratory” individuals are characterized by larger head size and for the length of limbs segments. The fluctuating range of the head width in specimens collected in the wild is much wider, due to the heterogeneity of the micro-climatic conditions of the larvae development and trophic resources. Maximal negative asymmetry of the head width is observed in individuals C. vicina R.-D. of the “natural” sample as compared with “laboratory” individuals. Among imagoes caught in the wild the individuals with a relatively wide head are dominated, as evidenced by the large positive value of kurtosis. At the same time, the distribution of values in “laboratory” individuals is almost normal. In adults bred in the laboratory the shortening of segments of the leg pair I is observed in comparison with the individuals of “natural” sample. Similar results were recorded for other insect groups cultivated in a laboratory. For most other linear measurements of the C. vicina R.-D. body the differences between samples are not registered. Ephemeral existence of the substrate of blow flies leads to higher prevailing evolutionary adaptation of species to varying micro-climatic conditions inside cadaveric material. A minor variation of morphometric characteristics indicates the resistance to changes in abiotic environmental factors. Thus, use of Calliphora vicina R.-D. (in the temperature range of +17…+28 °C as an indicator species of changes in the environmental temperature factor is not appropriate.

    Full Text Available In Algeria, coccidiosis constitutes one of the main constraints which hinder the development of the poultry production and is responsible for major losses to the poultry industry, reducing performance and increasing production costs, especially an increase of mortality and misuse of antibiotics. These molecules have fatal effects on the animal and public health, thus, alternatives were introduced, in particular the extracts of plants. The present study, conducted in October 2013, was carried out in five hundred broiler chicks (Hubbard F15 strain. The chicks were monitored from birth to the 52nd day. These animals, with homogeneous weight of 93 g and mixed sexes, came from the same hatchery and underwent the same environmental conditions. Animals of the first lot, identified as “Control lot” received a food exempt from any additive but antibiotics added to water. The animals of the second lot, identified as “Experimental lot”, received a water exempt from any additive and the same food added with the Yucca Schidigera extract. The objective of this study was the evaluation of the oocystale excretion by Mac Master’s method to estimate the activity of the Yucca Schidigera extract. The results highlighted an increase of oocystale excretion until 82.250 oocysts.g-1 of feces in the control lot and 22.950 oocysts.g-1 of feces in the experimental lot. The average levels of oocysts were significantly lower during three weeks from J14 to J35 in the experimental lot, then remained comparable for the rest of the experiment period (J36 to J51. These results showed that this additive considerably reduced the coccidian eggs elimination and proved its efficiency in the coccidiosis control.

    Shang, C. [Boca Raton Regional Hospital (United States)

    2016-06-15

    The motion management in stereotactic body radiation therapy (SBRT) is a key to success for a SBRT program, and still an on-going challenging task. A major factor is that moving structures behave differently than standing structures when examined by imaging modalities, and thus require special considerations and employments. Understanding the motion effects to these different imaging processes is a prerequisite for a decent motion management program. The commonly used motion control techniques to physically restrict tumor motion, if adopted correctly, effectively increase the conformity and accuracy of hypofractionated treatment. The effective application of such requires one to understand the mechanics of the application and the related physiology especially related to respiration. The image-guided radiation beam control, or tumor tracking, further realized the endeavor for precision-targeting. During tumor tracking, the respiratory motion is often constantly monitored by non-ionizing beam sources using the body surface as its surrogate. This then has to synchronize with the actual internal tumor motion. The latter is often accomplished by stereo X-ray imaging or similar techniques. With these advanced technologies, one may drastically reduce the treated volume and increase the clinicians’ confidence for a high fractional ablative radiation dose. However, the challenges in implementing the motion management may not be trivial and is dependent on each clinic case. This session of presentations is intended to provide an overview of the current techniques used in managing the tumor motion in SBRT, specifically for routine lung SBRT, proton based treatments, and newly-developed MR guided RT. Learning Objectives: Through this presentation, the audience will understand basic roles of commonly used imaging modalities for lung cancer studies; familiarize the major advantages and limitations of each discussed motion control methods; familiarize the major advantages and limitations of each discussed radiation beam control methodology and tumor tacking method; understand the key points in motion management for a high quality SBRT program.

    Full Text Available Este artículo describe los factores asociados al acoso laboral, entendido como una situación de trabajo en la que una persona se encuentra expuesta a actos en contra de su dignidad. Se presenta un estudio de caso, de carácter exploratorio, a partir de entrevistas en profundidad realizadas a personas que han vivenciado acoso laboral. A partir del análisis cualitativo de la información, los resultados señalan que la exposición al acoso laboral genera síntomas asociadas con el estrés postraumático: re experimentación, activación fisiológica y evitación. Se propone el estudio de estas situaciones en mayor profundidad y se concluye que una de las formas de apoyo a las víctimas empieza con la comprensión que puedan lograr a partir de narrar su experiencia y de entenderla como una situación violenta en el lugar de trabajo, asociada a los enfoques de productividad y competencia.

    Highlights: • α-MoB 2 powder synthesized under high pressure–temperature condition. • We have firstly investigated the equation of state of α-MoB 2 under uniaxial compression up to 85 GPa. • The complete elastic constant tensor of α-MoB 2 at high pressures up to 100 GPa are firstly calculated from density-functional theory (DFT). • We have investigated the strength of α-MoB 2 under uniaxial compression up to 85 GPa. - Abstract: Investigations of strength and equation of state of α-MoB 2 have been performed under nonhydrostatic compression up to 85 GPa using an angle-dispersive radial X-ray diffraction (RXD) techniques together with the lattice strain theory in a 2-fold panoramic diamond anvil cell at ambient temperature. The RXD data yields a bulk modulus and its pressure derivative as K 0 = 323(6) GPa with K 0 ′ = 4.59(27). The ratio of t/G is found to remain constant above ∼44 GPa, indicating that the α-MoB 2 started to experience yield with plastic deformation at this pressure. Together with theoretical results on high-pressure shear modulus, our results here show that molybdenum diborides sample could support a differential stress of ∼18 GPa when it started to yield with plastic deformation at ∼44 GPa under uniaxial compression. A maximum differential stress, as high as ∼25 GPa can be supported by molybdenum diborides at the high pressure of ∼85 GPa

    The purpose of this randomized, parallel, triple-blinded clinical trial was to compare efficacy and tooth sensitivity (TS) after use of an in-office bleaching agent of 6% hydrogen peroxide containing nanoparticles of nitrogen-doped titanium oxide (HP6) vs. 35% hydrogen peroxide (HP35). Forty-eight volunteers were randomly divided either a HP6 or HP35. Two clinical sessions were performed with an interval of 7 days between them for each group. In each session, two consecutive applications of each bleaching agent were performed and activated by a hybrid LED/laser light. Efficacy was determined by color alteration (ΔE), recorded with reflectance spectroscopy. It was assessed at baseline and after the first and second bleaching session. TS was characterized according to occurrence, intensity, duration, and type. Efficacy was analyzed by repeated measures analysis of variance (ANOVA) and post hoc Bonferroni test, and TS was analyzed by means of chi(2) test (α = 0.05). For HP35, highest and significant values of ΔE were found after bleaching when compared to HP6 (p = 0.002). However, HP35 showed a significantly higher occurrence of TS than HP6 (p = 0.008). Also, intensity and duration were higher in HP35. The majority of volunteers classified the type experienced in their sensitivity in the form of a "shock." The use of HP6 despite reducing efficacy when compared to an in-office bleaching in higher concentration (35%) produced less tooth sensitivity. In terms of tooth sensitivity, the use of lower concentrations of in-office bleaching should be the first choice, suggesting greater biocompatibility and safety compared to a conventional HP35.

    Full Text Available Abstract Background Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI. Methods Patients undergoing haemodialysis (HD via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions vs thrice per week heparin locks. Results Observed catheter days in the heparin (n=24 and ethanol (n=25 groups were 1814 and 3614 respectively. CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12. Flow issues requiring catheter removal occurred at a rate of 1.6 vs 1.4 per 1000 catheter days in the heparin and ethanol groups respectively (IRR 0.85; 95% CI 0.20-3.5 p =0.82 (for ethanol vs heparin. Conclusions Catheter survival and catheter-related blood stream infection were not significantly different but there was a trend towards a reduced rate of infection in the ethanol group. This study establishes proof of concept and will inform an adequately powered multicentre trial to definitively examine the efficacy and safety of ethanol locks as an alternative to current therapies used in the prevention of catheter-associated blood stream infections in patients dialysing with tunnelled catheters.

Oncologists completed a face-to-face, quantitative interview; patients completed a face-to-face interview, and a self-reported questionnaire. Oncologists and patients ranked treatment-induced OM among the three most important toxicities of cancer therapy requiring intervention. The most frequent OM symptoms reported by patients were oral ulcers (74%), dry mouth (73%), and difficulty swallowing (62%). Oncologists expected mild OM symptoms to last slightly longer than 1 week, whereas patients reported mild symptoms for more than 2 weeks. In mild-to-moderate OM, oncologists underestimated patients' pain experience. Overall, only 45% of oncologists said they would initiate OM prophylaxis when cancer therapy started. Of the 87% of patients who said they used their prescribed medications, only 16% reported using prophylactically prescribed medication. While oncologists' concerns related to the delays and interruptions of cancer treatment, patients tended to focus on the effects of OM on eating, drinking, and talking. Oncologists' and patients' perceptions about treatment-induced OM differ. To overcome discordant perspectives, there is a need to raise general awareness and improve proactive management of OM. As noted in recent guidelines, supportive cancer care is critical for ensuring optimal therapy and for improving the patient's experience.

    Full Text Available Improvements after precision dietary management of nitrogen rejection in two commercial dairy farms in Wallonia. Two dairy farms located in Pays de Herve and in Ardennes were followed at regular intervals in order to assess levels of nitrogen rejection. In Farm 1, the cows were divided into two groups: group HP contained high production cows and group BP contained cows with a lower production yield. Each group was offered a specific basal diet. In Farm 2, only one group of cows was assessed. The feed rations on both farms were characterized by a imbalance between the yields allowed by the energy or the nitrogen supplies and by an extremely high OEB balance of 794, 582 and 726 g, respectively, in groups HP and BP and in the Farm 2 group. Dietary changes were proposed in order to balance milk yields and to reduce the hypothesized nitrogen balance. The yield and urea content data from each milk record, along with data regarding nitrogen rejection, were statistically analyzed using a mixed model, which included an autoregressive covariance. The data from records 2, 3, 4 and 5 were then compared to the data from record 1. The advised changes implemented in the feeding management plan maintained milk yields at values similar to the yields observed in record 1 – 36.2, 24.3 and 23.0 l of 4% fat-corrected milk expressed for fixed days in milk produced by groups HP and BP and the Farm 2 group. The changes induced a significant reduction in the milk urea content (220 vs 300 mg·l-1 and a significant reduction in nitrogen rejection, whether expressed in terms of g per day per cow, g·l-1 or kg per year per cow. The cows in the Farm 2 group rejected less nitrogen in absolute terms (217.9 vs 260.1 g per day. However, it is interesting to note that the management approach in Farm 1 was more efficient in terms of nitrogen rejection since the level was on average 9 g·l-1 in comparison with 10 g·l-1 in Farm 2. In conclusion, it appears that, for either farm, whether an intensive or extensive management regime was being employed, the provision of well balanced feed rations led to a reduction in nitrogen rejection. It should, however, be noted that management advice needs to be provided on a farm by farm basis.

    Full Text Available Abstract Background Catheter-related bacteraemias (CRBs contribute significantly to morbidity, mortality and health care costs in dialysis populations. Despite international guidelines recommending avoidance of catheters for haemodialysis access, hospital admissions for CRBs have doubled in the last decade. The primary aim of the study is to determine whether weekly instillation of 70% ethanol prevents CRBs compared with standard heparin saline. Methods/design The study will follow a prospective, open-label, randomized controlled design. Inclusion criteria are adult patients with incident or prevalent tunneled intravenous dialysis catheters on three times weekly haemodialysis, with no current evidence of catheter infection and no personal, cultural or religious objection to ethanol use, who are on adequate contraception and are able to give informed consent. Patients will be randomized 1:1 to receive 3 mL of intravenous-grade 70% ethanol into each lumen of the catheter once a week and standard heparin locks for other dialysis days, or to receive heparin locks only. The primary outcome measure will be time to the first episode of CRB, which will be defined using standard objective criteria. Secondary outcomes will include adverse reactions, incidence of CRB caused by different pathogens, time to infection-related catheter removal, time to exit site infections and costs. Prospective power calculations indicate that the study will have 80% statistical power to detect a clinically significant increase in median infection-free survival from 200 days to 400 days if 56 patients are recruited into each arm. Discussion This investigator-initiated study has been designed to provide evidence to help nephrologists reduce the incidence of CRBs in haemodialysis patients with tunnelled intravenous catheters.

    To assess whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention. FFR is the mainstay of functional hemodynamic assessment of coronary artery lesions. The RXi Navvus system (ACIST Medical Systems, Eden Prairie, MN) is a monorail microcatheter with FFR-measurement capability through optical pressure sensor technology. This is an investigator-initiated, prospective, single-center, observational cohort study. A total of 238 patients were enrolled, 97 patients with Navvus and 141 with conventional pressure-wire based FFR (PW-FFR). Final analyses were performed on the cohort in which only 1 device was used (82 Navvus procedures vs. 136 PW-FFR procedures). No significant differences were found in the total amount of contrast used (150±77 vs 147±79ml; p=0.81), radiation use (6200±4601 vs. 5076±4655 centiG∗cm 2 ; p=0.09) or costs (€1994,- vs. €1930,-; p=0.32) in the Navvus vs. PW-FFR groups respectively. No significant differences were found in the amount of contrast used, total procedural costs or radiation when the Navvus system was used as compared to conventional FFR wires. CONTRACT is an investigator-initiated, prospective, single-center, observational cohort study that evaluated whether the RXi Navvus system compared to the use of standard Fractional Flow Reserve (FFR) wires reduces total contrast volume, radiation and overall study cost in a real world patient population referred for coronary angiography or percutaneous coronary intervention. Use of the RXi Navvus system was associated with comparable procedural costs, amount of radiation and contrast used as compared to PW-FFR systems. Copyright © 2017 Elsevier Ireland Ltd.

    高校音乐教育不仅要培养学生音乐方面的才华,传授音乐知识,还要充分发挥出音乐教育在德育教育方面的功能。音乐课程具备轻松性与娱乐性,旨在培养学生的音乐素养,并且通过其德育教育功能对学生的耳濡目染,将学生培养成德智体美劳全面发展的社会人才。音乐德育教育能够通过潜移默化的教学方式,将德育教育内容渗透其中,在教授文化课程的同时将德育教育与其并驾齐驱,因此对于培养学生的正确价值观具有重要意义。%College music education should not only cultivate stu-dents' talent in music and music knowledge, but also give full play to the moral education function of music education. Music course is relaxed and recreational, aiming to cultivate students' music accomplishment and cultivate them to be social talents with overall development of morality, intelligence, sports, aes-thetics and labor through the moral education function of music education. Through the infiltration of moral education contents into music education, cultural courses are developed together with moral education, so the moral education in music education is of great signigicance to the cultivation of students' correct val-ues.

    Methane in exhaust gas from biogas upgrading process, which is a greenhouse gas, could cause global warming. The biofilter with immobilized methane-oxidizing bacteria (MOB) is a promising approach for methane removal, and the selections of inoculated MOB culture and support material are vital for the biofilter. In this work, five MOB consortia were enriched at different methane concentrations. The MOB-20 consortium enriched at the methane concentration of 20.0% (v/v) was then immobilized on sponge and two particle sizes of volcanic rock in biofilters to remove methane in exhaust gas from biogas upgrading process. Results showed that the immobilized MOB performed more admirable methane removal capacity than suspended cells. The immobilized MOB on sponge reached the highest methane removal efficiency (RE) of 35%. The rough surface, preferable hydroscopicity, appropriate pore size and particle size of support material might favor the MOB immobilization and accordingly methane removal.

    2013-02-01

    Mobbing of predators occurs within a conspecific and heterospecific context but has not been quantified within the framework of a communication network and analysed with respect to heterospecific reciprocity. Here, we used playbacks of mobbing calls to show that mobbing is unequally distributed within a community of deciduous forest birds. Five species (great tit Parus major, blue tit Cyanistes caeruleus, marsh tit Poecile palustris, nuthatch Sitta europaea and chaffinch Fringilla coelebs) responded to each other's playbacks of mobbing calls. Commitment to mob was measured by minimum distance, response latency and uttering of calls. Commitment was higher when conspecific calls were broadcast. Yet, responses to heterospecific calls were significantly different between the five species. Chaffinches had the lowest commitment, and blue tits tended to have the highest. The communication network is asymmetric. Some species invest more than they receive from other species. As mobbing might incur costs, these are unequally distributed across the community.

  6. Methane-oxidizing seawater microbial communities from an Arctic shelf

    Marine microbial communities can consume dissolved methane before it can escape to the atmosphere and contribute to global warming. Seawater over the shallow Arctic shelf is characterized by excess methane compared to atmospheric equilibrium. This methane originates in sediment, permafrost, and hydrate. Particularly high concentrations are found beneath sea ice. We studied the structure and methane oxidation potential of the microbial communities from seawater collected close to Utqiagvik, Alaska, in April 2016. The in situ methane concentrations were 16.3 ± 7.2 nmol L-1, approximately 4.8 times oversaturated relative to atmospheric equilibrium. The group of methane-oxidizing bacteria (MOB) in the natural seawater and incubated seawater was > 97 % dominated by Methylococcales (γ-Proteobacteria). Incubations of seawater under a range of methane concentrations led to loss of diversity in the bacterial community. The abundance of MOB was low with maximal fractions of 2.5 % at 200 times elevated methane concentration, while sequence reads of non-MOB methylotrophs were 4 times more abundant than MOB in most incubations. The abundances of MOB as well as non-MOB methylotroph sequences correlated tightly with the rate constant (kox) for methane oxidation, indicating that non-MOB methylotrophs might be coupled to MOB and involved in community methane oxidation. In sea ice, where methane concentrations of 82 ± 35.8 nmol kg-1 were found, Methylobacterium (α-Proteobacteria) was the dominant MOB with a relative abundance of 80 %. Total MOB abundances were very low in sea ice, with maximal fractions found at the ice-snow interface (0.1 %), while non-MOB methylotrophs were present in abundances similar to natural seawater communities. The dissimilarities in MOB taxa, methane concentrations, and stable isotope ratios between the sea ice and water column point toward different methane dynamics in the two environments.
