Purpose The operational management of cold chain logistics has an important impact on the quality of cold chain products, but the service delivery process is subject to a series of potential problems such as product loss and cold storage temperature in the actual operation. Design/methodology/approach In this paper, the whole cold chain logistics system and risk events are analyzed. A Bayesian network is used for modeling and simulation to identify the main influencing factors and to conduct a sensitivity analysis of the main factors. Findings It is found that the operation of cold chain logistics systems can be divided into four links according to the degree of influence as follows: transportation and distribution, processing and packaging, information processing and warehousing. Transportation and distribution is the most influential factor of system failure, and extreme weather is the most risky event. At the same time, the four risk events that have the greatest impact on the operation of the cold chain system are in descending order: transportation equipment failure, extreme weather, unqualified pre-cooling and violation operation. Originality/value Therefore, enterprises should develop appropriate interventions for securing the transportation services, design strategies to deal with extreme weather conditions prior to and in the early stage of product delivery, and prepare additional effective measures for managing emergency events.

Purpose – In the digital age, constant changes in libraries inform contemporary building design. An innovative library building design is a complicated process and can be viewed as a continuous process of the use of tacit and explicit knowledge and innovative tools and approaches. Knowledge management (KM) can bring about the much needed innovation, and transform tacit knowledge to explicit knowledge. For the design of a library to be successful, it is necessary to apply KM to library building design. The purpose of this paper is to look at key change impacts, to explore how to manage knowledge in building design and to identify key design principles. Design/methodology/approach – This paper looks at key change impacts, explores how to manage knowledge in library building design and pinpoints design principles. Findings – This paper finds that KM can be vital to library building design, and it can be used in all stages: to examine the internal and external environments, transform tacit knowledge to explicit knowledge by using portals, and analyze existing and future issues and trends. When effectively used, KM will result in innovative design strategies and also will reduce the time and costs of the building design and plan processes. The main principles of library building design are flexibility, accessibility, safety and security, applicability, adaptability, efficiency, and sustainability. Practical implications – This paper provides a useful overview of how to manage knowledge in library building design and design principles. Originality/value – The views, discussions, and suggestions will be of value to improve the effectiveness of library building design.

Purpose The purpose of this paper is to explore potential drivers of high-growth intentions of early-stage entrepreneurs in Greece before and after the onset of the financial crisis of 2008. Design/methodology/approach To this end, the authors use individual-level data retrieved from Global Entrepreneurship Monitor annual surveys (2003-2015). Findings The results show that high-growth intentions of Greek entrepreneurs are driven by different factors in the crisis compared to the non-crisis period. Male entrepreneurs and entrepreneurs with significant work experience seem to be more likely to be engaged in growth-oriented new ventures during the crisis period. The same appears to hold for entrepreneurs who are motivated by an opportunity and also perceive future business opportunities in adverse economic conditions. On the other hand, the educational level and the social contacts of founders with other entrepreneurs are found to drive ambitious Greek entrepreneurship in the years before the crisis, while they were insignificant after the crisis outbreak. Originality/value Based on the concept of ambitious entrepreneurship, this study contributes to the literature by investigating the determinants of entrepreneurial high-growth expectations in the Greek context emphasizing the crisis period in comparison to the pre-crisis years.

Purpose The practice of social entrepreneurship has grown rapidly around the world, including in Malaysia where it is still considered to be at an early stage. Nevertheless, little is known about the career transition among youth who choose careers as social entrepreneurs. The purpose of this study is to explore the challenges faced by youth social entrepreneurs who run social enterprises in Malaysia. Design/methodology/approach This study used a qualitative approach to collect and analyse data to answer the research questions. Seven youth social entrepreneurs were interviewed until data saturation was met. An interview guide was created for the purposes of conducting the interviews. The interviews were recorded using a voice recorder. Data were transcribed verbatim and grouped in order to identify the codings, categories and themes. Findings The findings show the career transition to become a social entrepreneur, as well as the major challenges that youth social entrepreneurs face, which include acclimatising to the life and career of a social entrepreneur and not getting support from family. Practical implications The study findings are also significant for presenting valuable data on the experience of the developing social entrepreneur. The qualitative nature of the study provides valuable experiential insight into the lives and struggles of young social entrepreneurs in Malaysia. The findings will allow local authorities and social entrepreneurship regulatory agencies to design initiatives and plan actions intended to overcome the challenges. Originality/value This study makes an original contribution by showing that the process of career development as a social entrepreneur has given meaning to the informants. Despite presenting many challenges, social entrepreneurship has reinforced the role of youth social entrepreneurs, especially in relation to social responsibility.

Successful gold exploration projects depend on a piece of clear information on the association between gold, trace elements, and mineralization controlling factors. The use of soil geochemistry has been an important tool in pinpointing exploration targets during the early stage of exploration. This study aimed to establish the gold distribution, the elemental association between gold and its pathfinder elements such as Cu, Zn, Ag, Ni, Co, Mn, Fe, Cd, V, Cr, Ti, Sc, In, and Se and identify lithologies contributing to the overlying residual soils. From cluster analysis, a high similarity level of 53.93% has been shown with Ag, Cd, and Se at a distance level of 0.92. Au and Se have a similarity level of 65.87% and a distance level of 0.68, hence is proposed to be the most promising pathfinder element. PCA, FA, and the Pearson's correlation matrix of transformed data of V, Cu, Ni, Fe, Mn, Cr, and Co and a stronger correlation between Pb and U, Th, Na, K, Sn, Y, Ta and Be shows that source gold mineralization might be associated with both hornblende gneisses interlayered with quartzite, tonalite, and tonalitic orthogneiss. From the contour map and gridded map of Au and its pathfinder elements, it has been noted that their anomalies and target generated are localized in the Northern part of the area. The targets trend ESE to WNW nearly parallel to the shear zones as a controlling factor of Au mineralization emplacement.Supplementary material:https://doi.org/10.6084/m9.figshare.c.5721965

Early Phases

Purpose The traditional construction delivery method is challenged by low trust and collaboration issues, resulting in increased project costs. The integrated project delivery (IPD) method is developed, through a contractual agreement, to overcome these challenges by creating a common set of terms, expectations and project goals. Design/methodology/approach A singular construction case was followed during a four-month period. Data collection consisted of contract documents and a series of semi-structured interviews with representatives from the owner, design-group and contractors. Findings The IPD contract was found to have a number of positive effects; it improved project behavior (e.g. trust, collaboration and communication), increased ownership among project participants and improved buildability of the design, leading to fewer surprises and interruptions in the construction phase. The study also revealed a number of challenges including contractual and legal challenges and involving too many participants in the early phases. Moreover, co-location was identified as a particular important supporting element, to build relations and improve collaboration. Originality/value This research identified lessons learned from the application, as well as initial barriers and persistent barriers for implementing IPD. To improve IPD application the top three lessons were as follows: 1) the contractual documents should be adapted and signed at an early stage as this increases financial transparency, 2) cost estimates should be carried as an iterative process and project main concept be freezed at an early stage to increase understanding and minimize risks, 3) only the most important project developers should be involved in the early phases, to avoid going into detailed design issues before the main concept is completed.

PurposeFor Internet celebrities, self-disclosure (SD) is a crucial step in building relationships with their followers who perceive this communication as para-social interaction (PSI), which facilitates socialization among followers. Normative commitment (NC) is critical for creating bonds among community members that are strengthened through socialization. However, research on the predictive relationships among SD, PSI and NC has been insufficient. This paper aims to investigate the effects of two facets of Internet celebrity SDs (i.e. private life and opinion) and two facets of PSI (i.e. companionship and following) on NC. The mediating role of PSI on the effects of SD on NC was also analyzed.Design/methodology/approachPeople who follow at least one Internet celebrity on a social networking site were recruited to participate in this study, and 494 valid questionnaires were collected for examination. The collected data were analyzed using structural equation modeling (SEM).FindingsThe results revealed that both private-life and opinion SDs have positive effects on companionship and following PSI, which consequently influence NC. A mediation test revealed that companionship and following PSI mediate the effects of private-life and opinion SD on NC. This study's findings also revealed that NC is influenced more by following PSI than it is by companionship PSI. Furthermore, opinion SD was determined to be the more influential factor in following PSI, whereas private-life SD was the more influential factor in companionship PSI.Originality/valueThis paper is useful for understanding the influence mechanism of the SD of Internet celebrities on PSI and NC.
