Holonomic systems can be represented by a bond graph in which inertial variables are related to generalized variables using a multiport displacement-modulated transformer structure. It is shown that the part of the generalized forces due to inertial elements can be found either by direct calculation or by the operations of Lagrange's equations. Although no gyrators are needed for the representation, gyrational coupling may exist. Alternative representations may involve gyrators explicitly and it is possible to construct kinetic co-energy functions for these gyrators for use in Lagrange's equations. 相似文献

As practitioners of the imperial sport of the Victorian age, cricketers rallied whenever war descended upon England and its colonies. The South African War of 1899-1902 was no different. Adding to existing work on cricket's imperial development within South Africa, this study marks a significant contribution to research on the link between masculinity, war and sport during the Victorian era. A concept emerging from the English public schools of the mid- to late nineteenth century, the masculine ethos of sport and military honour had reached colonial South Africa by the outbreak of war in 1899. In its analysis of cricket and masculinity, this essay examines the events surrounding the war in South Africa and provides an example of the distinct relationship that existed between the military and the masculinity of sport and its organisation during this era. 相似文献

Several governments are actively encouraging their administrations to deliver public services exclusively through digital channels. This strategy consists of putting in place a series of complex and specific actions that bring into play numerous actors, to ensure that users are willing to accept digital channels and that weaker users are not disadvantaged. Although this strategy is being increasingly adopted in various countries, scholars have scarcely begun to explore its logic. This research explores how to define a service delivery strategy that forces users to adopt digital channels. Four in-depth case studies have been conducted on Italian local governments that started delivering their non-educational school services through digital channels alone. We found that a mandatory service delivery strategy is feasible when the starting point is to understand the users' characteristics, skills and behaviours and, as a consequence, whether they perceive the service as complex and/or ambiguous. With this in mind, public organisations can select the proper mix of channels for each category of users and combine their change in approach with behavioural-type interventions, i.e. by creating the right conditions to modify the users' behaviour. 相似文献

The authors present the feasibility and acceptability of a parent sexuality education program led by peer educators in community settings. They also report the results of an outcome evaluation with 71 parents who were randomized to the intervention or a control group and surveyed one month prior to and six months after the four-week intervention. The program was highly feasible and acceptable to participants, and the curriculum was implemented with a high level of fidelity and facilitator quality. Pilot data show promising outcomes for increasing parental knowledge, communication, and monitoring of their adolescent children. 相似文献

This study investigated teachers’ knowledge of, and capacity to identify resilience, in 92 primary school children in Far
North Queensland. It was found that although teachers’ knowledge of resilience was apparently strong, and they reported a
significant level of confidence in their ability to assist children in building resilience, their capacity to identify levels
of resilience in their students was lacking. The paper concludes with suggestions for future research. 相似文献
