Previous research has addressed the importance of IOC, where the outcome of a poor IOC between actors in a network will affect the information sharing and the inter-organizational relationship. The topic has been extensively researched, however researchers are still highlighting the need to further research.   A literature review on the topic area generated an overview of the existing literature within the field. The literature review identified a research gap that founded the purpose of this study. The purpose is to reveal the actors within the industry and how the IOC is structured among three cruise line destinations in Sweden and in the network Cruise Baltic.    The study was of a qualitative nature and was conducted through a multiple case study. Data was collected through semi-structured interviews with three cruise line destinations and one cruise line industry network.   The interview data reveals the IOC of the chosen industry and that the destinations have some barriers to overcome when it comes to achieving an effective IOC. Based on the conclusions of this study recommendations for managerial implications were formed.   The findings of the research were able to support previous studies regarding IOC and its key variables. It was revealed that the destinations and the network execute an effective IOC to some extent. The destinations are considerable small in size, which has influenced the IOC to the other actors within the network.

Purpose: This work systematically reviews the extant academic management literature on supply networks. It specifically examines how network configurations and network governance mechanisms influence each other in supply networks. Design: 125 analytical and empirical studies were identified using an evidence-based approach to review the literature mainly published between 1985 and 2012. Synthesis: Drawing on a multi-disciplinary theoretical foundation, this work develops an integrative framework to identify three distinct yet interdependent themes that characterize the study of supply networks: a) Network Configurations (structures and relationships); b) Network Governance Mechanisms (formal and informal); and c) The Interplay between Network Configurations and Network Governance Mechanisms. Findings: Network configurations and network governance mechanisms mutually influence each other and cannot be considered in isolation. Formal and informal governance mechanisms provide better control when used as complements rather than as substitutes. The choice of governance mechanism depends on the nature of exchange; role of management; desired level of control; level of flexibility in formal contracts; and complementary role of formal and informal governance mechanism. Research implications: This nascent field has thematic and methodological research opportunities for academics. Comparative network analysis using longitudinal case studies offers a rich area for further study. Practical Implications: The complexity surrounding the conflicting roles of managers at the organisation and network levels poses a significant challenge during the development and implementation stage of strategic network policies. Originality/value: This review reveals that formal and informal governance mechanisms provide better control when used as complements rather than as substitutes.

Acceptance of information technology (IT) has remained a topic of interest for a last few decades. Several theories, specifically over the conceptualisation of the technology acceptance model (TAM) have emerged and they have been applied in different contexts to investigate new insights into the acceptance behaviour at individual and organisational levels. However, despite TAM’s maturity and validity in different contexts, very little published literature strives to extend its capability to predict individuals’ acceptance behaviour about an online banking information system (OBIS). A possible rational for this gap may be conceptualisation of the TAM under which individuals’ acceptance behaviour can only be predicted with two beliefs: perceived ease of use (PEOU) and perceived usefulness (PU). The evidence in literature shows that PU and PEOU beliefs are not sufficient; hence, they may not explain individuals’ acceptance behaviour in emerging contexts, such as online banking information systems, especially in developing economies such as Pakistan. There is therefore a need for inclusion of any additional factor that can enhance prediction of acceptance of online banking information system by potential users. Extending research on the TAM, this study developed and tested a model of OBIS acceptance. The proposed model integrated key constructs from the information systems acceptance research stream into the theoretical frame of the TAM and other theories from social psychology, such as the theory of reasoned action (TRA), theory of planned behaviour (TPB) and the TAM2. According to the proposed conceptual model, OBIS acceptance was determined by eight main factors, which included perceived usefulness, perceived ease of use, trust, technological self-efficacy, response time, output quality, accessibility, and terminology clarity. In this model, PU was hypothesised to be affected by PEOU, trust, technological self-efficacy (TSE), output quality (OQ) and response time (RT). In addition, PEOU was hypothesised to be determined by three external factors: TSE, accessibility and terminology clarity (TC). The model was tested on a sample of 353 Internet banking users in Pakistan. Using structural equation modelling with Analysis of Moment Structures (AMOS) software, data analysis showed considerable support for the extended hypothesised model. The result indicated that, in order of importance, PU, PEOU and trust explained 45.7 % of the variance in the acceptance behaviour. The trust and the TSE predicted 28.1 % of the variance in the PU. However, the hypothesised relationships between the PU and the PEOU, OQ and RT were found to be not significant. While in the PEOU, 21.8 % of the variance was predicted by the TSE, accessibility and TC. TSE was found to be a more influential determinant of the PEOU than the PU. The consideration of factors that have a significant influence on the acceptance of OBIS, as identified in this research, is important for the managers in the banking sector, especially in developing countries, in order to increase wider acceptance and use of these systems, which provide benefits to both the customers and the service providers.

Social media is a newer emerging media outlet that could serve as a good communication tool for companies, marketers, and advertisers alike; yet, studies into the effects that social media may have on people’s perceptions is more limited. The goal of this research study is to investigate whether or not social media has the ability to influence people’s perceptions of brands. It applies cultivation theory to social media and specifically looks at whether or not social media can cultivate brand affect, trust, and loyalty. As a result, this study will allow for potential understanding of how to use social media effectively to communicate messages and where additional research can be done to better understand this newer media outlet. / text

The academic achievement gap is one of the most important areas of inquiry in education today. Racial-ethnic disparities in achievement continue to be persistent at every level—including post-secondary education. Research suggests African American males are particularly likely to disidentify with academics, resulting in a lack of a significant relation between academic self-concept and academic outcomes. Research has found a relationship between racial-ethnic messages that parents give to their children and academic achievement. Further, the student’s gender may impact the types of parental messages given. Multiple regression statistical analysis will be used to determine if the relation between academic self-concept and GPA is moderated by parental racial-ethnic socialization, teacher mistrust, and gender. / text

A current national priority is improving secondary school mathematics performance. National initiatives have attempted to help improve student achievement through curricular changes and stringent testing requirements; yet, these initiatives fail to consider the importance of student-teacher relationships in student motivation and achievement. High school students' trust in their mathematics teachers can lead to better relationships and increased feelings of competence, or mathematics self-efficacy, which is consistently linked to achievement. Student trust is based on perceptions of a teacher's competence, benevolence, openness, reliability, and honesty. The aim of my study is to determine the effect of trust in a teacher on student mathematics self-efficacy over the course of a school year, accounting for differences between individual students. The sample consisted of 230 ninth through twelfth grade students (57% girls) from a large high school in central Texas. Students reported their trust in their math teachers and their math self-efficacy at 4 time points. Growth curve modeling was utilized to model the effect of trust on self-efficacy over time. The results indicate that trust predicted self-efficacy over the course of the school year such that for a one point change in trust there was a corresponding .4 point change in self-efficacy. Gender was also a significant predictor of self-efficacy, with girls reporting lower self-efficacy on average. However, girls did not report lower trust, and the relation between trust and self-efficacy was not moderated by gender. Inasmuch as future studies should seek to expand on these findings, this study is an important first step into investigating the link between trust in teachers and self-efficacy. The results of this study serve to inform teachers, researchers, and policy makers of the importance of recognizing student-teacher relationships as an important factor in building student confidence and motivation. / text

Parents' refusal to immunize their children with the measles, mumps, and rubella (MMR) vaccine has resulted in a surge of measles outbreaks in the United States. The purpose of this correlational study was to examine the relationships between parental knowledge and trust of the MMR vaccine, and their trust in government and medical authorities. The theoretical foundation for this study was the health belief model (HBM). This study determined if there was any relationship between general trust in doctors/governments (i.e., the predictor variable) and attitudes toward MMR vaccine (i.e., the sole dependent variable), and whether gender, age group, or level of education moderated that general trust. A Survey Monkey subscriber database and researcher-developed survey was used to identify and email 2,500 parents of immunization-aged children, resulting in 237 respondents who met the required parameters. The analysis revealed a significant, positive relationship between the criterion and predictor variables, R = .32, R2 = .10, F(1, 235) = 26.39, p. < .001, regardless of gender, age, or education, suggesting an association between higher trust and greater likelihood of a parent allowing vaccination. This study offers significant insights for positive social change by providing pediatricians, primary health care providers, and vaccine educators, with information for communicating with vaccine-hesitant parents: It is not enough to address parental concerns of vaccine safety, efficacy, and necessity. It is also not enough to provide evidence-based scientific data, as doing so has been proven to be ineffectiveâ??and for some parents counter-productiveâ??when government and medical authorities are sited as the source. What we need to do is start focusing upon the role of parental trust, including how to best establish that trust, and equally important, what steps are necessary to sustain that trust.
