Impact of tourniquet during knee arthroplasty: a bayesian network meta-analysis of peri-operative outcomes.

INTRODUCTION: The role of tourniquet during knee arthroplasty is controversial. The present study compares various tourniquet protocols using a Bayesian network meta-analysis of peri-operative data. MATERIAL AND METHODS: The present study was conducted in accordance with the PRISMA extension statement for reporting systematic reviews incorporating network meta-analyses of health interventions. The literature search was conducted in September 2020. All clinical trials investigating the role of tourniquet in knee arthroplasty were considered for inclusion. Methodological quality was assessed using Review Manager 5.3. A Bayesian hierarchical random-effects model analysis was used in all comparisons. RESULTS: Ultimately, pooled data from 68 studies (7413 procedures) were analysed. Significant inconsistency was found in the data relating to total estimated blood lost; no assumption could be made on this outcome. Full-time tourniquet resulted in the shortest surgical duration and lowest intra-operative blood lost, in both cases followed by incision-to-suture. The incision-to-suture protocol achieved the smallest drop in haemoglobin during the first 72 h post-operatively and the lowest rate of blood transfusion, both followed by full-time tourniquet. Hospitalisation was shortest in the absence (no-tourniquet) group, followed by the cementation-to-end group. CONCLUSION: For knee arthroplasty, longer tourniquet use is associated with the shorter duration of surgery, lower intra-operative blood lost, lower drops in haemoglobin and fewer transfusion units. The shortest average hospitalisation was associated with no tourniquet use

“Emotional Exhaustion and Perceived Corporate Social Responsibility: A Case Study of a Port Logistics Organization”

In an era of economic crisis, and at the shadow of major ethical scandals in organizations, Corporate Social Responsibility (CSR) strategy has emerged as a crucial element to reestablish the bond between corporations and all other stakeholders such as the local community, society and labor force. Crisis makes employees more stressful, since they work on unwarranted jobs causing them emotional exhaustion. This study aims to examine the association between employee emotional exhaustion and perceived corporate social responsibility (CSR). For this purpose, this study conducted a survey which examines if CSR (ethical, social, environmental dimensions) is negatively related to emotional exhaustion of employees on a sample of 93 employees of a port logistics management services organization. A structured questionnaire was developed in order to measure emotional exhaustion and employee perceptions about CSR activities. Building on the claim that employee perceptions of CSR activities may significantly related to emotional state, this paper examines three CSR dimensions (social, ethical and environmental) and emotional exhaustion. The results of this study indicate that environmental CSR exerts a negative significant effect on Emotional exhaustion. These finding will be of great value as they can contribute on understanding the impact of environmental CSR on emotional exhaustion with detrimental effects on employees’ productivity, job performance, and creativity. The importance of CSR environmental aspects and the relative strategies guiding CSR impact on emotional exhaustion affecting job-related outcomes are also discussed

Do agile managed information systems projects fail due to a lack of emotional intelligence?

YesAgile development methodologies (ADM) have become a widely implemented project management approach in Information Systems (IS). Yet, along with its growing popularity, the amount of concerns raised in regard to human related challenges caused by applyingADMare rapidly increasing. Nevertheless, the extant scholarly literature has neglected to identify the primary origins and reasons of these challenges. The purpose of this study is therefore to examine if these human related challenges are related to a lack of Emotional Intelligence (EI) by means of a quantitative approach. Froma sample of 194 agile practitioners, EI was found to be significantly correlated to human related challenges in agile teams in terms of anxiety, motivation, mutual trust and communication competence. Hence, these findings offer important new knowledge for IS-scholars, project managers and human resource practitioners, about the vital role of EI for staffing and training of agile managed IS-projects

Residents’ Perceptions Toward Cultural, Social and Economic Benefits and Costs of Tourism Industry: An Empirical Survey

Tourism development plays a crucial role for the local economy and residents’ quality of life, especially for Greece, a country suffering from financial crisis. The purpose of the paper is to examine attitudes of residents of a capital city at a prefecture of Central Greece that is Chalkida, the capital of Evia Island, toward tourism development. It was selected as it shares several similarities with most destinations of the neighboring region of Thessaly. Factor analysis of scaled items measuring their attitudes resulted in eight tourism-related factors: beneficial economic, social and cultural influences, welfare impacts, economic cultural and social costs of tourism development and community support. Results indicate residents’ expectations from tourism development were not met, as community support toward tourism sector is rather limited. Economic costs of tourism development exert detrimental effects on the welfare of residents, as well as their cultural and social context. In this way, tourism industry lacks community support and as a consequence a rather alienated environment for tourism developments is nurtured. On the contrary, economic benefits are strongly and positively related to welfare, culture benefits, and community support on cultural or historic based tourism. Alike, welfare is associated with social and cultural benefits. Moreover, younger residents are less opting to support tourism development although they share the same perceptions about tourism development with older ones. © 2016, Springer International Publishing Switzerland

Sustainability, Social Marketing and Host Attitudes About Tourism in the City of Larissa

This paper builds on the Social Norm Approach (SNA) which emphasises the role of norms in shaping attitudes, intentions and behaviour, in order to ground a socially desired behaviour change favouring, for example sustainability. Indeed, environmental sustainability may be regarded as a collective challenge that can only be achieved if a sufficient number of residents cooperate. Hence, the community plays a crucial role to effect lasting changes towards a more ecocentric behaviour. However, higher levels of awareness and knowledge of environmental issues among the general public have not led to the implementation of actual sustainable practices. This study aims to investigate the association of ecocentric attitude with the costs and benefits of urban tourism development. Drawing from a sample of residents in the city of Larissa (Thessaly region), ecocentric attitude shapes the profile of tourism development, recognising higher economic and social benefits, as well as higher costs on natural and cultural environment. © 2017, Springer International Publishing Switzerland

Perceived Corporate Social Responsibility and Job Satisfaction in a Port Logistics Organization

Job satisfaction is a crucial factor if a company wants to sustain their employs. Several studies investigated the role of job satisfaction and they have found out that satisfied personnel will help on future recruiting, will help on retaining key employees and it will make employees more motivated. Since corporate responsibility can be a factor that can affect job satisfaction, it is highly important to examine their relationship. Moreover, as a consequence of the global economic crisis, there is a growing interest about the responsibility of corporations towards the society, local communities, and the environment. For the aforementioned reasons, the purpose of this paper is to examine if ethical, social, and environmental dimensions of perceived corporate social responsibility are positively related to job satisfaction. The field research is based on a sample of 93 employees of a port logistics management services organization. A structured questionnaire was developed in order to measure employee perceptions about CSR activities and their impact on job satisfaction. Building on the claim that employee perceptions of CSR activities may significantly related to workplace attitudes, this paper examines three CSR dimensions (social, ethical and environmental) and job satisfaction. The outcomes of this research delineate that only Social CSR exerts a positive significant effect on job satisfaction, highlighting the importance of CSR activities with social impact and worth aiming at caring for the well-being of others (suppliers, customers, community, and employees). Managerial and theoretical implications are developed based on survey results
