Abstract
The concept of national fitness has promoted the construction and development of public sports. And how to effectively implement the layout of urban public sports planning has become a hot topic. Based on this, in the study, the layout and integration of the public sports cities in modern cities for the national fitness were mainly discussed. First of all, the research background of the planning and layout of public sports in modern cities under the concept of national fitness was expounded, and the development of urban public sports theory was briefly outlined. Then, the planning and layout of public fitness in modern cities were analyzed. Finally, through the planning and construction projects of public sports in modern cities, the design of public fitness corridor, community road and Sports Park was carried out. It is proved that the scientific and rational planning of sports cities can promote the development of the city.

Abstract
Purpose
The purpose of this paper is to explore the relationship between employee perspectives of high-performance work systems and employee outcomes, i.e. job satisfaction and affective commitment, and to propose ways of increasing the positive effects of high-performance work systems on firm performance.
Design/methodology/approach
The data were collected from 370 employees in the Chinese manufacturing industry during 2010. The Analysis of Moment Structures (AMOS) method was used to test each of the eight hypotheses deriving from the conceptual framework.
Findings
The paper finds that: employee perspectives of high-performance work systems have a positive effect on both job satisfaction and affective commitment; and breadth of behavioural script and level of autonomy mediate the relationship between employee perspectives of high-performance work systems and their attitudes towards that organisation (job satisfaction and affective commitment); however, skill variety did not mediate the relationship between employee perspectives of high-performance work systems and employees’ attitudes in the data set used.
Practical implications
The findings of the paper suggest that managers can improve employees’ attitudes by integrating effective high-performance work systems in their working environment. Even more interestingly, it appears that by encouraging broad behavioural scripts or allowing employees more freedom to apply their skills, managers can improve employees’ attitudes more significantly than by encouraging employees to acquire a variety of skills.
Originality/value
Using signalling and psychological-contract theory, the paper shows the dominant influence of employees’ perceived high-performance work systems on employees’ attitudes via behavioural scripts and autonomy.

Abstract
Purpose
Drawing on and extending the push-pull-mooring (PPM) framework, this paper aims to empirically explore the influencing mechanism of traveler switching intention from the hotel reservation platforms to the sharing accommodation platforms (SAPs).
Design/methodology/approach
This study adopts structural equation modeling to analyze the 543 responses collected among hotel reservation platforms and SAPs travelers.
Findings
The results support the positive effect of both push factors (e.g. dissatisfaction with product, service and information quality of hotels on the hotel reservation platform) and pull factors (e.g. price value, authenticity, interaction, home benefits and novelty of SAPs) on traveler switching intention. Except for the negative effect of switching cost, other mooring factors including prior switching experience and social influence positively affect traveler switching intention. The authors also found the switching cost negatively and prior switching experience positively moderated the push effects on traveler switching intention, while the social influence positively moderated the pull effects on traveler switching intention.
Research limitations/implications
Recommendations of future SAP participation research to consider the competing platforms, the unique experiences of SAPs and mooring factors. Examining the factors of different sources is also useful for practitioners to better understand travelers’ demands and to improve the overall welfare of travelers.
Originality/value
This paper embraces an extended PPM framework to explore traveler switching intention in online travel platforms. Moreover, this paper provides unique insights into the switching behavior from the hotel reservation platforms to the SAPs.

Abstract
From the perspective of business history, this chapter presents an overview of the development of the tourism sector in South America, placing special emphasis on the Peruvian case. The chapter explores various topics related to the tourism chain, such as hotel networks, the role of the state, tour operators, micro- and small enterprises, linkages between tourism and sustainability, the formation of clusters in the sector, and interactions between different entrepreneurs in the chain. Special emphasis is placed on the Peruvian case, especially when it comes to discussing the role of micro- and small enterprises in the sector.

Abstract
This chapter examines the professional identities of Brazilian journalists. It does so through an analysis of the growing professional autonomy of journalism from 1950 to 1990 through the life stories of 10 intellectual-journalists, individuals whose journalistic activities have crossed over into other intellectual fields.
This study applies a symbolic interactionist framework to understand how these actors managed their reputations and careers within the intellectual world. The narratives were taken from qualitative semi-structured interviews, and supported by additional research such as interviews, biographies, and articles which have been published about their lives.
The life stories were compared to the extensive structural changes affecting the world of journalism and the world of intellectuals in Brazil. This comparison revealed gaps between these two spheres of practice, within which the ambivalent form of journalists’ identities have been constructed.
This chapter offers two contributions to the study of Brazilian journalists. From a theoretical and methodological viewpoint, it advances beyond other studies that focus more on the prevailing representations of journalists’ professional identities and their role in society. From an empirical standpoint, it describes the complex negotiations between the worlds of journalism, culture and politics. This chapter also reexamines the current dominant explanation for the changes in Brazilian journalism. It shows that building careers and new levels of interpersonal cooperation for intellectuals and journalists has been a slow process. Ultimately, this development has left some behind, especially those actors stretched between multiple professional identities such as those who self-identify as intellectual-journalists.

Abstract
This chapter examines the relationship between news media in Cinema Novo films to underscore the impact of their shared discourse on the history of Brazilian films.
The author discusses the emplotment of news media within representative Cinema Novo films whose narratives speak to an ongoing debate concerning the role of print and televisual journalism in the increasingly repressive political environment of the military dictatorship installed in the 1960s. Interpretations on the level of film narrative, of specific scenes, and of shot and shot-sequencing contribute to the discussion, situated within the broader historical context of the established laws and commissions of 1960s Brazil.
Together, the analyzed films’ various interventions in Brazilian cultural and political history offer a complex representational fabric simultaneously constituting and critiquing national discourse.
The present research is limited to films of the 1960s but has implications for the interpretation of many Brazilian films and for Brazilian film history writ large. The overlap of film and news media is abundantly evident in the films of the Retomada and New Millennial Brazilian Cinema, but they do not fit within the scope of this chapter.
This analysis discusses a major canonical film (Entranced Earth) alongside lesser-known films (Threatened City, Freedom of the Press). When considered together in the light of their shared reflections concerning news media, these films bring up previously underexamined issues within the respective fields of Communication Studies and Brazilian Film Studies.

Abstract
Purpose
The purpose of this paper is to investigate the effect of Na2SiO3 concentration on the microstructure and corrosive properties of microarc oxidation (MAO) coating on Al-Mg-Sc alloy and explore microstructure evolution rule of Al substrate in the contact area.
Design/methodology/approach
The Na2SiO3 concentration in electrolytes influenced the microstructure and corrosion behavior of MAO coatings. Instantaneous high temperature and high pressure due to microarc discharge caused annealing treatment. The corrosive behavior of the MAO coating was featured with polarization curves and electrochemical impedance spectrum in 3.5 Wt.% NaCl solution.
Findings
The substrate in the contact area existed the instantaneous annealing treatment, which caused obvious recrystallization. The coating prepared in electrolyte containing 7 g/L Na2SiO3 exhibited the highest protective properties in 3.5 Wt.% NaCl solution.
Originality/value
MAO treatment could increase the corrosion resistance by producing a protective layer on the Al-Mg-Sc alloy surface at a suitable Na2SiO3 concentration and microstructure evolution rule of Al substrate in the contact area was obtained.

Abstract
Purpose
The purpose of this paper is to explore the effect of ZnO on the structure and properties of micro-arc oxidation (MAO) coating on rare earth magnesium alloy under large concentration gradient.
Design/methodology/approach
The macroscopic and microscopic morphology, thickness, surface roughness, chemical composition and structure of the coating were characterized by different characterization methods. The corrosion resistance of the film was studied by electrochemical and scanning Kelvin probe force microscopy. The results show that the addition of ZnO can significantly improve the compactness and corrosion resistance of the MAO coating, but the high concentration of ZnO will cause microcracks, which will reduce the corrosion resistance to a certain extent.
Findings
When the concentration of zinc oxide is 8 g/L, the compactness and corrosion resistance of the coating are the best, and the thickness of the coating is positively correlated with the concentration of ZnO.
Research limitations/implications
Too high concentration of ZnO reduces the performance of MAO coating.
Practical implications
The MAO coating prepared by adding ZnO has good corrosion resistance. Combined with organic coatings, it can be applied in corrosive marine environments, such as ship parts and hulls. To a certain extent, it can reduce the economic loss caused by corrosion.
Originality/value
The effect of ZnO on the corrosion resistance of MAO coating in electrolyte solution was studied systematically, and the conclusion was new to the common knowledge.
