Objectives:To describe the professional quality of life and explore its associated factors among nurses coming from other areas of China to assist with the anti-epidemic fight inWuhan and especially examine whether the hospital ethical climate was independently associated with nurses’professional quality of life.Methods:A cross-sectional online survey was conducted from March 2020 to April 2020.The nurses working in Wuhan from the other parts of China were the target population.The Professional Quality of Life Scale version 5,the Hospital Ethical Climate Survey,and a basic information sheet were used to collect data.Descriptive statistics,t-test,ANOVA,Pearson correlation,and multiple linear regression analysis were used to analyze the data.Results:In total,236 nurses participated in this study,and 219 valid questionnaires were analyzed.The average age of the participants was 31.2±5.0 years.Most nurses were female(176/219;80.4%)and married(145/219;66.2%).In term of professional quality of life,nurses reported moderate(129/219;58.9%)to high(90/219;41.1%)levels of compassion satisfaction,low(119/219;54.3%)to moderate(100/219;45.7%)levels of burnout,and low(67/219;36.0%)to high(10/219;4.6%)levels of secondary traumatic stress.Regarding hospital ethical climate,nurses reported moderately high hospital ethical climates with an average score of 4.46.After controlling for socio-demographic characteristics,the multiple linear regression models showed that the hospital ethical climate subscale of“relationship with physicians”was independently associated with the compassion satisfaction(b=0.533,P<0.01)and burnout(b=0.237,P<0.05);the hospital ethical climate subscale of“relationship with peers”(b=0.191,P<0.01)was independently associated with the secondary traumatic stress.Conclusions:During the early stage of the pandemic,nurses demonstrated moderate to high level of compassion satisfaction,low to moderate level of burnout,and all nurses experienced secondary traumatic stress.Nurses perceived a high level of hospital ethical climate,and the perceived hospital ethical climate played an important role in promoting nurses’professional quality of life during a lifethreatening infectious disease pandemic. 展开更多

In 2012, 92 Administrative, Technical and Service Staff (ATS S) grievances (unresolved departmental conflicts) were referred to the Industrial Relations arm of the HR division of the UWI St Augustine Campus. Of these trade disputes, 52 cases were "resolved" and 10 unresolved cases were referred to the Ministry of Labor. In 2009, 692 disputes from various organizations nationally were lodged at the Industrial Court of Trinidad and Tobago--781 in 2010, 778 in 2011 and at September 25th, 2012, 566 were filed (Swamber, 2012). Vincent Cabera, president of the Banking, Insurance and General Workers Union, expressing his grave concern about these statistics cited inter alia, noted that "work stoppages that currently persist in society owed to the malfunctioning of the industrial relations system of the twin island". Legitimate members of the Recognized Majority Union (RMU), who have within the past year at the Campus experienced unresolved conflicts at the departmental level that progressed to trade disputes will be eligible to participate and electronically administered a semi-structured questionnaire developed to determine the frequency and causes of unresolved conflict, their perceptions of its handling, as well as Form A of the Rahim Organizational Conflict Inventory II (ROCI-II) (Rahim, 1983) to classify the conflict management style of their Heads of departments. 展开更多

Those technologies created by humans have had a big impact on both daily and business lives. Newspapers, Radio, TV and Cinema are obvious examples of this impact. Dinting the last two decades of 20th century, spread of personal computers transformed the way people live0 work and think. Some people evaluated the situation as revolution and others as threat to humans. Intemet, in this respect, is considered as mass media. People connect the Internet without time and space limitations. However, communication on the Internet is not mass commtmication because it requires every individual or organization to have a unique Intemet Protocol address (IP) to commtmicate. Because of its peer to peer communication nature just as in the telephone communication, this feature distinguishes Intemet from other commtmication media. On the other hand, it resembles mass communication media because of its mobility, spread and functionality both for sender and receiver. In many sectors, including communication and information technology sectors, mobility, spread and functionality features lead the way to increase interactivity between parties in communication. Businesses benefited the "interactivity tool" for many purposes: to increase market share for a product or service, to increase customer satisfaction, or to increase amount of information about their customers, competitors or suppliers in order to make strategic decisions. For journalism and generally, for mass media, interactivity is an important aspect of the business. Media corporations must know the needs of their audience before they express and take precautionary steps to satisfy them. This forces the mass media sector to increase interactivity in customer communication. In this paper, we researched the intemctivity effect in journalism that we see especially in internet journalism applications. The research aims to cover opinions of newspapers, advertisers and audience on interactivity and future of mass media communication. For this purpose, fmdings of a survey have been evaluated. 展开更多
