Job stressors have a considerable influence on workplace safety behaviors. However, the findings from previous studies regarding the effect of different types of job stressors have been contradictory. This is attributable to, among other factors, the effectiveness of job stressors varying with occupations and contexts. This study examines the effects of challenge and hindrance stressors on construction workers' informal safety communication at different levels of coworker relationships.

A three-dimensional framework of informal safety communication is adopted, including self-needed, citizenship and participatory safety communication. Stepwise regression analysis is then performed using questionnaire survey data collected from 293 construction workers in the Chinese construction industry.

The results demonstrate that both challenge and hindrance stressors are negatively associated with self-needed and citizenship safety communication, whereas their relationships with participatory safety communication are not significant. Meanwhile, the mitigation effects of the coworker relationship (represented by trustworthiness and accessibility) on the above negative impacts vary with the communication forms. Higher trustworthiness and accessibility enable workers faced with challenge stressors to actively manage these challenges and engage in self-needed safety communication. Similarly, trustworthiness promotes workers' involvement in self-needed and citizenship safety communication in the face of hindrance stressors, but accessibility is only effective in facilitating self-needed safety communication.

By introducing the job demands-resources theory and distinguishing informal safety communication into three categories, this study explains the negative effects of challenge and hindrance job stressors in complex and variable construction contexts and provides additional clues to the current inconsistent findings regarding this framework. The diverse roles of challenge and hindrance job stressors also present strong evidence for the need to differentiate between the types of informal safe communication.

This study aims to develop an improved understanding of the formation of citizens' purchase intention to increase the adoption of prefabricated housing (PH).

An integrative model of the theory of planned behavior (TPB) and norm activation model (NAM) was proposed based on previous studies. To verify the conceptual model, an analysis was conducted after data collection from a questionnaire survey. Lastly, findings were presented by explaining the formation of purchase intention in the egoistic and altruistic contexts. Practical implications were likewise discussed.

Findings manifest that citizens' purchase intention is influenced by egoistic and altruistic cognitions. An effective strategy is to show citizens the pro-environmental features of PH to promote its adoption because they value the environmental performance of housing. Meanwhile, consumers' social fitness also plays an essential role in decision-making, and the dual contradiction in the PH market is revealed.

This study extends the knowledge of psychological decision-making theories in the field of purchase intention toward PH by proposing an integrative framework of TPB and NAM. Results indicate a systematic and comprehensive understanding of consumers' decision-making in the PH domain. Moreover, results of this research contribute to specifying and refining the applicable contexts of TPB and NAM by adding two antecedents: subjective knowledge and environmental concern. This research contributes to the literature by being one of the first to investigate purchase intention toward a high-cost product with invisible technological innovation.

This paper critically analyses the urban memory and heritage interpretation of postcolonial Harbin, a city in China that was founded by the Russians in 1898. It investigates the role and making of Russian colonial heritage in contemporary Harbin with a detailed case study of the Harbin Railway Station

Research methods include archival analysis, observation and semi-structured interview. In-depth interviews were conducted with local people, architect/urban planners and officials.

Local people of different generations with different backgrounds have different interpretations of the recently made colonial heritage of the Harbin Railway Station. The urban memory of Harbin has been consistently re-forming with both nostalgia and amnesia. Younger generations tend to regard the colonial heritage as their own heritage and a symbol of Harbin's cultural character without considering much about its related colonial history. In today's Harbin, colonial heritage as the “colonial past presencing” is more about a feel of the Europeanised space rather than the actual historical events of the period, and colonial heritage making becomes a tool for urban development and revitalisation at the institutional level. However, due to the paradigm shift in China's urban development, Harbin is facing new challenges in dealing with its colonial heritage.

Harbin is an under-researched case in terms of urban heritage studies. This paper offers a new entry point for understanding the westernisation and colonial heritage making in the contemporary China more deeply and thoroughly and helps to see the trend of China's urban development more clearly.
