The purpose of this study is to analyze the effect of China’s potential domestic emission control area (DECA) with 0.1 per cent sulphur limit on sulphur emission reduction.

The authors calculate the fuel cost of a direct path within the DECA and a path that bypasses the DECA for ships that sail between two Chinese ports in view of the DECA. Ships adopt the path with the lower cost and the resulting sulphur dioxide (SO₂) emissions can be calculated. They then conduct sensitivity analysis of the SO₂ emissions with different values of the parameters related to sailing distance, fuel price and ships.

The results show that ships tend to detour to bypass the DECA when the distance between the two ports is long, the ratio of the price of low sulphur fuel and that of high sulphur fuel is high and the required time for fuel switching is long. If the time required for fuel switching is less than 12 h or even 24 h, it can be anticipated that a large number of ships will bypass the DECA, undermining the SO₂ reduction effect of the DECA.

This study points out the size and shape difference between the emission control areas in Europe and North America and China’s DECA affects ships’ path choice and SO₂ emissions.

In North America, delegated practice “medical direction” models are often used as a proxy for clinical quality and safety in paramedic services. Other developed countries favor a combination of professional regulatory boards and clinical governance frameworks that feature paramedics taking lead clinician roles. The purpose of this paper is to bring together the evidence for medical direction and clinical governance in paramedic services through the prism of paramedic self-regulation.

This narrative synthesis critically examines the long-established North American Emergency Medical Services medical direction model and makes some comparisons with the UK inspired clinical governance approaches that are used to monitor and manage the quality and safety in several other Anglo-American paramedic services. The databases searched were CINAHL and Medline, with Google Scholar used to capture further publications.

Synthesis of the peer-reviewed literature found little high quality evidence supporting the effectiveness of medical direction. The literature on clinical governance within paramedic services described a systems approach with shared responsibility for quality and safety. Contemporary paramedic clinical leadership papers in developed countries focus on paramedic professionalization and the self-regulation of paramedics.

The lack of strong evidence supporting medical direction of the paramedic profession in developed countries challenges the North American model of paramedics practicing as a companion profession to medicine under delegated practice model. This model is inconsistent with the international vision of paramedicine as an autonomous, self-regulated health profession.

The current study aims to investigate if different measures related to online psychosocial well-being and online behavior correlate with social media fatigue.

To understand the antecedents and consequences of social media fatigue, the stressor-strain-outcome (SSO) framework is applied. The study consists of two cross-sectional surveys that were organized with young-adult students. Study A was conducted with 1,398 WhatsApp users (aged 19 to 27 years), while Study B was organized with 472 WhatsApp users (aged 18 to 23 years).

Intensity of social media use was the strongest predictor of social media fatigue. Online social comparison and self-disclosure were also significant predictors of social media fatigue. The findings also suggest that social media fatigue further contributes to a decrease in academic performance.

This study builds upon the limited yet growing body of literature on a theme highly relevant for scholars, practitioners as well as social media users. The current study focuses on examining different causes of social media fatigue induced through the use of a highly popular mobile instant messaging app, WhatsApp. The SSO framework is applied to explore and establish empirical links between stressors and social media fatigue.

The purpose of this paper is to identify and classify the various initiatives developed and implemented across the globe for the abatement of maritime air emissions.

In this paper, an extensive survey of various sources was conducted, including the official reports of international and regional institutions, government policy documents, port authority websites, classification society pages, private firms’ sites and the academic literature. The initiatives were then categorized in accordance with the classification of the Swedish Environmental Protection Agency and analyzed using the SPSS Statistics software to give some insight into their frequencies and the interrelationships between them.

This exploratory review resulted in the establishment of a comprehensive global database of initiatives encouraged by the whole range of shipping stakeholders and decision-makers for the reduction of shipping air emissions. According to the findings, economic incentives that provide motivation for the adoption of less environmentally damaging practices are the most commonly used initiative, followed by infrastructure investments and informative policies.

The results provide implications for further research that include an in-depth analysis of ports’ policies, as well as an evaluation of initiatives applied on a large scale to map their emissions reduction potential for shipping.

The main contribution of this paper is the identification and analysis of all the diverse initiatives implemented globally in a comprehensive way and its dealing with air pollution from shipping as a whole.

This study aims to contribute knowledge about different professional identities represented among HR practitioners from Weber's “ideal types” framework.

The paper is based on semi-structured interviews with 34 Swedish HR practitioners working in large public and private organisations.

The findings reveal that HR practitioners' identity is perceived as indistinct, unclear and shattered, which leaves lots of room for interpreting HR identity. Based on a thematic content analysis, three different ideal-type identities are presented, each representing the characteristic traits of an HR identity type. These are the Defender who always supports the managers, the Disturber who questions the managers in favour of the employees and the Driver who focuses on the economic expansion of the organisation.

One of the potential constraints of this study is the authors’ reliance on interview data. This finding implies that future research can employ mixed methods or observational techniques to bridge the gap between narrated responsibilities and real-time actions. The data source, predominantly from larger organisations, presents another limitation. This raises a significant research implication: there is a need to study identity formation among HR practitioners in smaller organisations. The theoretical framework this study contributes can aid in comprehending HR practitioners' identities and their corresponding actions. Continued research might explore the significance of these ideal-type identities.

The model presented provides a new way of understanding HR practitioners' complex and shattered professional identity and the various stakeholders that direct different expectations towards them. This knowledge can be used both in HR education and in HR work as a basis for discussing the social work environment of HR practitioners and negotiating their work and identity.

The study contributes knowledge of the professional identities of HR managers, an under-researched area, especially when it comes to empirical research about the HR practitioners' own experiences of their everyday work and view of the HR profession.

Drawing on media richness theory and a framework of interpersonal communication goals, this study investigates how and why the IT industry's top managers use communication media to achieve their interaction goals in e-leadership.

A qualitative research approach is applied to understand top managers' communication media use and interaction goals. The empirical data were gathered through semi-structured interviews with 33 top managers from large IT companies and analysed using theory-guided thematic and ideal-type analyses.

Top managers were categorized into three types, based on their communication goals through face-to-face communication. Relationship-oriented top managers pursued relational and communal goals, whereas task-oriented ones wished to achieve instrumental and communal goals. Task- and relationship-oriented top managers pursued relational, instrumental, and communal goals. This study indicates that communal, instrumental, relational, and self-presentational goals influence managers' communication media selection.

This study brings new knowledge to the management communication research field. It expands the framework of interpersonal communication goals by identifying communal goals as a new category, in addition to existing instrumental, relational and self-presentational goals. This study suggests that media richness theory could be advanced by recognizing that a broader set of communication goals – including communal, instrumental, relational, and self-presentational – influences managers' communication media selection.

In this paper, the authors integrate the psychological ownership theory with the concept of commitment to contribute to the discussion on agricultural supply chain management. The purpose of this study is to examine how farmers experience their commitment to the business relationship with the processor and how this is conveyed through the routes of psychological ownership.

The empirical data are based on 14 in-depth face-to-face Finnish farmer interviews. To understand the farmers’ routes to psychological ownership, the critical incidents technique was used.

According to the three routes to psychological ownership – control, profound knowledge and self-investment – the authors argue that farmers mainly consider their routes to be more or less blocked because of the asymmetrical power and information distribution in the business relationship with the processor. Furthermore, based on farmers’ perceptions of psychological ownership, the authors provide a farmer typology that reflects in the farmers’ willingness to commit to the business relationship. The identified types are named as satisfied, captives and leavers.

By integrating the theory of psychological ownership with the concept of commitment, this study provides a more robust understanding of how farmers experience their commitment to the business relationship, thus, contributing to the literature on supply chain management in the agri-food business context. Implementation of these findings can help business partners to proactively improve their business relationships through the perceived level of commitment and to deal with critical incidents influencing the effectiveness of the whole chain.

Existing research focuses on the pension systems and reforms in China from a macro-level and financial perspective. The expectations of mid-life Chinese people regarding their retirement and pensions have been ignored to date, and this research set out to address this lacuna.

The application of qualitative research methods is relatively novel in Chinese social science. As a grounded theory (GT) study, the research reported here deployed semi-structured interviews to investigate middle-aged Chinese women's and men's perceptions of their pensions and retirement. In total, 36 interviews were conducted, following the constructivist GT method.

The data point to disparities between the choices and perceptions of individuals on the one hand and the official assumptions underlying the current pension regime on the other hand. Research participants had varying interpretations of the inequality in retirement incomes in China, the main division being between enterprise workers and public-sector employees.

Although there are in principle rigidly fixed retirement ages for men and women in contemporary China, the phenomena of early retirement and working post-retirement are increasing. There are trade-offs between work/retirement and family needs, which influence the choices of middle-aged citizens. Retirement pathways are increasingly individualised, reflecting broader patterns of individualisation and inequality in China.
