Abstract
Purpose
The quality of probiotic yogurt which is remarked as a healthy, therapeutic and nutritious food product strongly depends on starter types and their compositions; however, the choice of starter culture affects the taste, aroma and quality of the final product. Through this study, to obtain favorable quality attributes of probiotic yogurt, a mixture of two thermophilic/mesophilic starter cultures (YC- 350/YC- X16) was applied for fermentation.
Design/methodology/approach
The effects of starter mixture, probiotic Lactobacillus paracasei and storage time on quality indices, such as apparent viscosity, water holding capacity, syneresis, post acidification rate and probiotic viability (L. paracasei), were assessed through using a combined (mixture-process) statistical design.
Findings
The results revealed that changes in viscosity and syneresis depend on the amount of YC- X16. Acidification rate was more pronounced at higher levels of YC- 350 (1.22 per cent) in comparison to that in YC-X16 (1.08 per cent) during storage time. With respect to probiotic viability, L. paracasei count was more than 107 cfu/mL during refrigerated storage time. Moreover, a promotive effect of YC- 350 on L. paracasei proliferation was observed in this study.
Originality/value
The favorable yogurt, from qualitative aspects, was manufactured at 75:25 per cent ratio of YC- X16:YC- 350 in probiotic type yogurts. Therefore, the use of mixed starter cultures developed textural properties of probiotic yogurt beside L. paracasei survival.

Abstract
Information technology has become an essential part of the rapid and accurate transfer and processing of enormous volumes of data processed in international transport firms and port organisations. The proper management of systems, which process this information and communicate it to those who manage port operations, is vital for efficient transport. This explains why container‐tracking systems are given high priority among operational computer applications in ports. Investigates the importance of information technology and its role in improving the operational systems in cargo handling. A computer simulation model is developed to compare two different operational systems – a container terminal equipped with electronic devices versus a terminal without such devices. The importance of information technology in supply‐chain management is also discussed.

Abstract
Purpose
Prior research in ingredient branding (IB) has identified several important decision variables consumers use when evaluating IB alliances. This exploratory research aims to investigate the relationship between these variables and consumers’ buying likelihood of the IB alliance and the relative importance of these variables for low- vs high-involvement product categories.
Design/methodology/approach
A study with the participation of 458 mTurkers was conducted and the data were analyzed using random forests.
Findings
Findings reveal relative importance of different variables for an IB alliance and that these differ for low- vs high-involvement categories.
Research limitations/implications
Being exploratory in nature, this research has several limitations, such as using only one high- and one low-involvement categories.
Practical implications
Results of this research will help brand managers as they make decisions entering an IB alliance as well as with investing their budget on different aspects of their brand, and tailoring their marketing activities for low- vs high-involvement product categories.
Originality/value
To the best of authors’ knowledge, this paper is the first to discuss the relative importance of different decision variables in an IB context empirically.

Abstract
Given the backdrop of a global influx of refugees and high numbers of youth under the age of 18 among counts of forcibly displaced persons, this chapter examines the literature on educational experiences among resettled refugees in Western countries. Young refugees typically face a complex set of unique challenges and adversities including disruptions in their schooling, displacement, exposure to potentially traumatic events, and resettlement stressors. Youth and parent interactions with schools are influenced by linguistic and cultural differences, which can make it difficult to communicate and advocate for young refugees' educational needs. The chapter provides a review of educational literature on resettled refugee youth. We use a socioecological framework and offer a protective and promotive lens, including psychosocial issues, to consider for school-based prevention and intervention programs. The chapter builds upon Pastoor (2015), who advocated a holistic approach with refugee students in school-based settings.

Abstract
Purpose
Aged-care work has become an extreme form of work. Anti-violence HRM, comprising practices to combat workplace violence, is important in an industry with widespread violence. In this paper, we employ social exchange theory to better understand the effect of anti-violence HRM and trust in the manager on perceived nurse and PCA cynicism working in Australian aged care facilities and their subsequent intention to leave.
Design/methodology/approach
This study used a mixed method with two stages. Stage 1 comprised semi-structured interviews with 10 managers and 50 nurses and PCAs working in Australian aged care facilities. Stage 2 comprised a survey of nurses and PCAs with a total of 254 completed responses in Time 1 (first wave) and 225 completed responses in Time 2 (second wave).
Findings
We tested three hypotheses and reported that interestingly anti-violence HRM was positively associated with organisational cynicism. Organisational cynicism mediated the relationship between anti-violence HRM and intention to leave. Worker trust in the manager moderated the relationship between anti-violence HRM practices and organisational cynicism, such that high levels of trust in the manager increased the effect of anti-violence HRM practices to reduce organisational cynicism and subsequently reduce intention to leave.
Originality/value
We find evidence that in aged care, workers' trust in their managers is critical for effectual anti-violence HRM. We argue that implementation of HRM practices may be more complex in extreme work settings. It is crucial to study HRM in situ and understand the root of social exchange(s) as a foundation for HRM to influence employee attitudes and behaviour.

Abstract
Purpose
This study aims to propose a simple experimental method to distinguish the galvanic corrosion, crevice corrosion and self-corrosion in metal/carbon fiber reinforced polymer (CFRP) joints.
Design/methodology/approach
The corrosion behaviors of four different galvanic couples, whose anodes were Zn-coated DP590 steel and Al 6022, and cathodes were two kinds of CFRP, were investigated in immersion and GMW14872 cyclic conditions.
Findings
The results showed that the galvanic corrosion caused by direct contact between CFRP and metals was more serious than that caused by the jointing bolts. The corrosion damage caused by crevice corrosion was severer than that caused by galvanic corrosion. Self-corrosion was also significant, particularly under the cyclic salt spray condition.
Practical implications
Cyclic salt spray test may more reliably simulate the galvanic corrosion of a joint in industrial service environments, and real corrosion damage may be underestimated by a galvanic current measurement.
Originality/value
A deeper understanding of different corrosion mechanisms involved in CFRP/metal joints under different service conditions in industry has been given.

Abstract
Purpose
The purpose of this paper is to classify research on information and communication technology (ICT) for logistics and freight transportation on the basis of the main themes and methods and proposes directions for future research.
Design/methodology/approach
The review is based on 44 papers published from 1994 to 2009 in international peer‐reviewed journals. The academic papers are analysed and classified according to the research methodology adopted and the themes addressed.
Findings
While there are many contributions taking the “public transportation” perspective (i.e. the viewpoint of public stakeholders), papers focussing on the “private transportation” perspective (i.e. the viewpoint of the private companies offering logistics and transportation services) are fewer and relatively more recent. Additionally, even though in recent years researchers have also started to examine the decision‐making process of ICT adoption, many themes are under‐represented in literature, such as the subject of integration among different application types, empirical research on ICT adoption and the role of technology providers in the adoption process. As far as the methodology is concerned, the review revealed that many of the papers examined are either conceptual papers or empirical studies (i.e. mostly based on surveys, or else on case studies or interviews), while simulation and modelling are rarely present.
Research limitations/implications
While efforts were made to be all‐inclusive, significant research efforts may have been inadvertently omitted. However, the authors believe that this review is an accurate representation of the body of research on ICT for logistics and transportation companies published during the specified timeframe, and feel that confidence may be placed on the resulting assessments.
Originality/value
The paper offers a guide for the review of previous research on this topic and identifies the most important issues that need to be addressed in future research.

Abstract
There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.
An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).
The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.
In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.
The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.
