A research paper by Muecke and Eadie (2020) lists some 25 Aboriginal walking trails that are led by Aboriginal guides. This is the unique ‘selling point’ for these kinds of trails, since there are many more trails and tracks that are resourced by signage alone, or which may be led by non-Indigenous guides.

Nowadays there are many types of glass fiber reinforced polymer(GFRP) composite beam and column joints, such as standard connection, bolted through connection, angle steel connection, tube connection and so on, most of which connected by high-strength bolts with round holes. In this paper, monotonic loading tests on GFRPcomposite beam and column joints connected by slotted-hole bolts were conducted. To compare the performance of different joints, two groups of specimens were used in this study; one of group was the beam-column joints connected by the angle steel, and other group was connected by the tube connection. Specimens with different bolt holes, side plate reinforcement condition, and different bolt pre-tightening forces were studied. Failure modes, bending moment curves, plastic rotation, and yield stiffness of the two groups of joints were compared. Results showed thatthe ultimate bending moment bearing capacity of specimens with side plates could be increased by 30%. Under the same conditions, the bearing capacity of the tube joints was about 10% larger than that of the angle steel joints. Although the bearing capacity of joints was not increased by using slotted holes, plastic rotation capacity and yield stiffness of joints with slotted-hole bolts were 1.1 times than that of the ordinary round-hole bolts joints. Monotonic loading tests on GFRP composite beam and column joints connected by slotted-hole bolts were conducted. To compare the performance of different joints, two groups of specimens were used in this study; one of group was the beam-column joints connected by the angle steel, and other group was connected by the tube connection. Specimens with different bolt holes, side plate reinforcement condition, and different bolt pre-tightening forces were studied. Failure modes, bending moment curves, plastic rotation, and yield stiffness of the two groups of joints were compared. The test loading device was a single channel electro-hydraulic servo loading system. The level of actuator deformation range was 200 mm, which could exert the maximum load of 250 kN. To facilitate loading, the GFRP column was fixed under the loading device. By applying a vertical displacement actuator in the beam end and connected actuator by a steel tube at GFRP beam loading point, it was to ensure the stability of loading position and keeping verticality of actuators. The rotation angles and bending moment of the joint were calculated according to the related equations. So the relation of moment-rotation of joints could be obtained to analyze mechanical performance for GFRP composite beam and column joints connected by slotted-hole bolts.

This brief discussion paper documents key points arising from the Overseas Visit (24-28 June 2002) to the Institut National de la Recherche Agronomique (INRA) Joint Research Unit – Innovation in Montpellier, France1. The purpose of the visit was to: 1. Investigate the relevance of INRA agricultural extension practice to CRC Rice Project 5204; 2. Explore the potential for INRA – CRC Rice collaboration in agricultural extension. Key points arising from the visit are as follows: 1. Elements common to the French and Australian contexts of agricultural extension and rice production were identified during the course of the visit; 2. Social theory central to the research framework of CRC Rice Project 5204 was recognised as critically informing INRA agricultural extension practice; 3. INRA require an authoritative statement of CRC Rice intent in agricultural extension if the opportunity for collaboration is to be further developed.

This paper explores trends in beverage preference in adolescents, identifies related regional differences, and examines cluster differences in key drinking measures. Data were obtained from the European School Survey Project on Alcohol and Other Drugs (ESPAD), covering 24 European countries between 1999 and 2019. Trends in the distribution of alcoholic beverages on the participants’ most recent drinking occasion were analysed by sex and country using fractional multinomial logit regression. Clusters of countries based on trends and predicted beverage proportions were compared regarding the prevalence of drinkers, mean alcohol volume and prevalence of heavy drinking. Four distinct clusters each among girls and boys emerged. Among girls, there was not one type of beverage that was preferred across clusters, but the proportion of cider/alcopops strongly increased over time in most clusters. Among boys, the proportion of beer decreased, but was dominant across time in all clusters. Only northern European countries formed a geographically defined region with the highest prevalence of heavy drinking and average alcohol volume in both genders. Adolescent beverage preferences are associated with mean alcohol volume and heavy drinking at a country-level. Future approaches to drinking cultures need to take subpopulations such as adolescents into account.
