The purpose of this paper is to explain the work and importance of the “extension” programme in the USA.

An historical review of the formation, development, present day workings and importance of the extension programme.

“Extension” works in six major areas, including family, consumer science and agriculture. Extension grants that address food safety are issued via the National Integrated Food Safety Initiative (NIFSI). Target audiences for the programmes include various groups of consumers (pregnant/nursing mothers, infants, teens, etc.), as well as multipliers or gatekeepers who disseminate knowledge to groups of consumers.

Since the Year 2000, NIFSI have awarded more than 180 competitive integrated food safety grants. Federal data indicate 20 percent reduction in foodborne disease attributed to collaborative educational efforts including the development of HACCP.

This paper is one of the few to describe the work of the extension programme with specific reference to food safety.

The progressive limits to rights mobilization have become starkly apparent in the past two decades. No new suspect classes have been forthcoming from the Supreme Court since 1977 despite continued demands for legal recognition by lesbians and gays, indigenous peoples and others interested in expanding civil rights doctrine. Public tolerance for civil rights measures has likewise dried up. Since the 1960s, referenda on civil rights have halted affirmative action programs, limited school busing and housing discrimination protections, promoted English-only laws, limited AIDS policies, and ended the judicial recognition of same-sex marriage, among other issues. Nearly 80% of these referenda have had outcomes realizing the Madisonian fear of “majority tyranny”¹ and signaling the Nietzschean dread of a politics of resentment (Brown, 1995, p. 214; Connolly, 1991, p. 64).

Given the importance of online social network (OSN) media features, many studies have focused on how different types of OSNs with various media features influence users’ usage and engagement. However, a recent literature review indicates that few empirical studies have considered how different types of OSNs with different information accessibility levels influence users’ beliefs and self-disclosure. By comparing two OSN platforms (OSNs with high-level information accessibility vs OSNs with low-level information accessibility), the purpose of this paper is to address this opportunity by investigating the differential impacts of the two platforms on individuals’ psychological cognition – particularly users’ social exchange beliefs – and explaining how these beliefs translate into OSN self-disclosure.

This study used a factorial design approach in an experimental setting to examine how different levels of information accessibility (high vs low), influence the social exchange beliefs (i.e. perceived social capital bridging, perceived social capital bonding and perceived privacy risks) of OSN users and subsequently influence OSN self-disclosure.

The results show that users on OSNs with high-level information accessibility express significantly higher perceived social capital bridging and perceived privacy risks than users on OSNs with low-level information accessibility. However, users on OSNs with low-level information accessibility express higher social bonding beliefs than users on OSNs with high-level information accessibility, indicating that there are different effect mechanisms toward OSN self-disclosure.

The focus of this research helps unveil the complex relationships between OSN design features (e.g. information accessibility), psychological cognition (e.g. social capital bridging, social capital bonding and privacy risks) and OSN self-disclosure. First, it clarifies the relationship between information accessibility and self-disclosure by examining the mediating effect of three core social exchange beliefs. Second, it uncovers the distinct effects of high-level information-accessible OSNs and low-level information-accessible OSNs on OSN self-disclosure.

This paper aims to explore the use of importance‐performance analysis (IPA) as an evaluative technique for public management decision making.

Based on a literature review of convention, exhibition and meeting management, a number of attributes were identified that influence destination choice from convention exhibitors' and delegates' perspectives. Responses were obtained from 177 convention exhibitors and delegates who attended an Asia Expo in Macao Special Administrative Region (SAR), the People's Republic of China.

Factor analysis reveals that the selected importance attributes are grouped into six categories: “professional convention services”, “extra‐convention opportunities”, “convention supporting services”, “accommodations”, “cost” and “image”. The importance‐performance analysis shows that Macao SAR has strong infrastructure support and traditional tourist attractions but lacks specialized convention experts and mechanisms for pricing strategies.

The use of importance‐performance analysis is explored in assessing the competitiveness of Macao SAR as a city for international conventions. The research findings indicate that IPA is an effective method and has the potential to become a valuable strategic management and decision‐making tool.

Macao SAR, it is suggested, should adopt a synergistic approach to develop its convention and general tourism industries in tandem since these two industries can complement each other in drawing upon the socio‐economic resources of the city.

This article contributes to the literature by extending the use of importance‐performance analysis for public management decision making.
