Advocacy programmes targeting street-connected children involve changing public and policy makers' perceptions about this group of often stigmatised children. Increasingly, such programmes centre leisure activities, sports, and sporting events as potential platforms for sharing messages aimed at effecting social change. For effective impact, such advocacy goals require that safe spaces are developed for emerging children's political messages and managing media narratives to centralise their individual challenges and, more importantly, the root-causes of their street-connectedness. In part influenced by an Ecological Framework for Human Development, we explore how the media engage meaningfully with Street Child United (SCU) events and how they represent street-connected children. Thematically analysing this media coverage, we explore SCU partners' relationships with the media and whether advocacy messages are communicated coherently and consistently. We found that messages of advocacy and children's rights are present, but inconsistently framed, reinforcing a binary between pity and inspiration, and limiting opportunities of challenging public perceptions and effecting change. For SCU, similar sports event organisers, and civil society organisations to successfully determine media narratives, they need to develop strategies to manage relationships and more continuous engagement with the media and other stakeholders to sustain interest and leverage impact

Health expenditure at around 5.7% GDP is low for a developed society like Hong Kong, which is unique in having a dual track of public and private services in its health care system. Such phenomenon has been steady over the last three decades, apparently not affected at all by a major change in the Government in 1997. The public and private sections have equal share of the total health dollars consistently over the years, despite the increase of Government's annual spending from 11% to 17% since 1990, implying a similar trend in the private sector, which is funded predominantly by out of the pocket expenses with some insurance contribution. However, Hong Kong has the longest life expectancy in the world. This has resulted in the increase in the demand for health and long-term care, casting doubt on whether the traditional model of financing and delivery of care will be sustainable. The Government has pledged that that no one is denied adequate medical treatment due to lack of means, a stance in existence for decades and being reflected by the steady state of public and private share of health expenditure. Apart from two major re-structuring of the governance system, there has been little change in the service provision organisations. The system is often criticized for being heavily hospital based and acute-centric, particularly in the public services. Primary care is taken up predominantly by the private sector, mostly in clinical services, not focusing on prevention. It is apparent that there is a significant service gap, that needs to be examined and addressed systematically before a practical solution can be formulated. A more holistic, humanistic and better integrated system of care, with innovative care patterns, shall be the way forward.

Assembly line designs in manufacturing commonly face the key problem of dividing the assembly tasks among the working stations so that the efficiency of the line is optimized. This problem is known as the assembly line balancing problem which is known to be NP-hard. This study, proposes a bi-objective genetic algorithm to cope with the assembly line balancing problem where the considered objectives are the utilization of the assembly line and the workload smoothness measured as the line efficiency and the variation of workload, respectively. The performance of the proposed genetic algorithm is tested through solving a set of standard problems existing in the literature. The computational results show that the genetic algorithm is promising in providing good solutions to the assembly line balancing problem. ; This study is supported by the European Union's Horizon 2020 research and innovation program under grant agreement no. 723711 through the MANUWORK project.

Abstract: We investigate how visual cues in universities discourage women from pursuing STEM. We extend research on ambient sexism (i.e., witnessing sexist mistreatment of others) to include environmental cues that women do not belong. Men were pictured in STEM buildings (Pilot Study 1) and described in university-sponsored STEM news articles (Pilot Study 2) twice as often as women. In an experiment, undergraduate women who read about male scientists reported less positive STEM attitudes relative to men who read about male scientists and women who read about female scientists. Women who read about and saw images of female scientists reported more positive STEM attitudes than women who simply read about female scientists. Depicting predominantly male scientists in universities negatively impacts female students.

To reduce the burden of the ageing population, time banking can be one of the possible approaches in the community to maximise social capital. Time banking aims to exchange one's time to serve others and the time of service can be saved as credit so as to swap for services when necessary. It can create a virtuous cycle for providing and receiving services. Several positive outcomes to service providers and recipients of time banking are identified in this review paper. Nevertheless, there is a lack of practical adoption of time banking in Hong Kong. To analyse the challenges of the adoption of time banking in Hong Kong, the current practices of time banking in Hong Kong will be evaluated. To promote time banking in Hong Kong, governmental, technical and educational support are recommended.

Purpose – This study aims to propose an efficient optimization algorithm to solve the assembly line balancing problem (ALBP). The ALBP arises in high-volume, lean production systems when decision makers aim to design an efficient assembly line while satisfying a set of constraints. Design/methodology/approach – An improved genetic algorithm (IGA) is proposed in this study to deal with ALBP in order to optimize the number of stations and the workload smoothness. Findings – To evaluate the performance of the IGA, it is used to solve a set of well-known benchmark problems and a real-life problem faced by an automobile manufacturer. The solutions obtained are compared against two existing algorithms in the literature and the basic genetic algorithm. The comparisons show the high efficiency and effectiveness of the IGA in dealing with ALBPs. Originality/value – The proposed IGA benefits from a novel generation transfer mechanism that improves the diversification capability of the algorithm by allowing population transfer between different generations. In addition, an effective variable neighborhood search is employed in the IGA to enhance its local search capability. ; CC BY-NC 4.0 ; This study is supported by the European Union's Horizon 2020 research and innovation program under grant agreement no. 723711 through the MANUWORK project.
