This study shows how family firm size affects the extent to which bus and coach operators in Australia interact with and contribute to their community by quantifying the value of eight social externalities and presenting the results, using the number of staff and the number of buses per operator as the denominators. The study highlights how a transaction between the government, as buyer, and the bus operator, as seller of services, can affect an external factor that being community and regional development. The results suggest that the small- and medium-sized family firm bus operators are the governance models most likely to contribute toward achieving community and regional development outcomes, which in turn, highlights the importance placed on the achievement of the non-financial goals of family firms and the socio-emotional wealth of the community in which it is embedded. This study suggests that it is possible that contracting bus-services for social value, rather than just lowest price, would create greater benefit for the community and this would offset any gains in economic efficiency achieved by large and non-family firms.

This paper discusses the nature of the Australian bus and coach representative environment and the role of the state-based voluntary professional association （SBVPA）. A literature review associated with memberships to which businesses subscribe for representation and linking social capital is presented, as well as a discussion on agency theory that possibly explains the member/association dynamic. The results of an Australia-wide survey of bus operators, which measures the extent of linking social capital between themselves and their SBVPA, are revealed. It is found that one state with consistently higher results may possess a competitive advantage in the form of a partnership agreement with the State Government Authority--an agreement that rests on co-operation and facilitates social capital. This evidence could contribute to the global narrative on how non-profit associations can be a mechanism for institutionalising social capital, sustain a firm＇s operation and encourage governments to increase their use of non-profit associations, as agents of government, to achieve public policy outcomes.

Development and demonstration of reliable measurement techniques that can detect and help quantify the nature and extent of elemental mercury （Hg（0）） in the subsurface are needed to reduce uncertainties in the decision-making process and increase the effectiveness of remedial actions. We conducted field tests at the Y-12 National Security Complex in Oak Ridge, Tennessee, USA, to determine if sampling and analysis of Hg（0） vapors in the shallow subsurface （〈0.3 m depth） can be used to as an indicator of the location and extent of Hg（0） releases in the subsurface. We constructed a rigid polyvinyl chloride push probe assembly, which was driven into the ground. Soil gas samples were collected through a sealed inner tube of the assembly and were analyzed immediately in the field with a Lumex and/or Jerome Hg（0） analyzer. Time-series sampling showed that Hg vapor concentrations were fairly stable over time, suggesting that the vapor phase Hg（0） was not being depleted and that sampling results were not sensitive to the soil gas purge volume. Hg（0） vapor data collected at over 200 push probe locations at 3 different release sites correlated very well to areas of known Hg（0） contamination. Vertical profiling of Hg（0） vapor concentrations conducted at two locations provided information on the vertical distribution of Hg（0） contamination in the subsurface. We conclude from our studies that soil gas sampling and analysis can be conducted rapidly and inexpensively at large scales to help identify areas contaminated with Hg（0）.

We report a facile strategy to synthesize intermetallic nanoparticle （iNP） electrocatalysts via one-pot pyrolysis of a zeolitic imidazolate framework, ZIF-8, encapsulating precious metal nanoparticles （NPs）. ZIF-8 serves not only as precursor for N-doped carbon （NC）, but also as Zn source for the formation of intermetallic or alloy NPs with the encapsulated metals. The resulting sub-4 nm PtZn iNPs embedded in NC exhibit high sintering resistance up to 1,000℃. Importantly, the present methodology allows fine-tuning of both composition （e.g., PdZn and RhZn iNPs, as well as AuZn and RuZn alloy NPs） and size （2.4, 3.7, and 5.4 nm PtZn） of the as-formed bimetallic NPs. To the best of our knowledge, this is the first report of a metal-organic framework （MOF） with multiple functionalities, such as secondary metal source, carbon precursor, and size-regulating reagent, which promote the formation of iNPs. This work opens a new avenue for the synthesis of highly uniform and stable iNPs.

A shibboleth is‘an old idea,principle or phrase,that is no longer accepted by many people as important or appropriate to modern life’(Advanced Learners Dictionary).The discourse of Teaching English as a Foreign Language is riddled with shibboleths that distort our thinking and disrupt our teaching *** aim of this paper is to expose the shibboleths,straighten out our thinking,and free our methods from obsolete and mischievous ideas.
