Recent analyses of protest policing in Western democracies argue that there has been a marked shift away from oppressive or coercive approaches to an emphasis on consensus based negotiation. King and Waddington (2005) amongst others, however, suggest that the policing of international summits may be an exception to this rule. This paper examines protest policing in relation to the 2005 G8 summit in Gleneagles, Scotland. We argue that 'negotiated management' cannot be imported wholesale as a policing strategy. Rather it is mediated by local history, forms of police knowledge and modes of engagement. Drawing on interviews and participant observation we show that 'negotiated management' works best when both sides are committed to negotiation and that police stereotyping or protestor intransigence can lead to the escalation of any given event. In closing we note the new challenges posed by forms of 'global' protest and consider the implications for future policing of protest. 相似文献

Excitement-seeking and related constructs have been associated with heavier gambling and negative health measures in problem
and/or pathological gamblers. Most adults gamble recreationally and an understanding of the relationship between excitement-seeking
as a motivation for gambling amongst subsyndromal gamblers has significant public health implications. Logistic regression
analyses were used to examine a national sample of past-year recreational gamblers (N = 1,476) to identify characteristics distinguishing gamblers acknowledging gambling for excitement (“Excitement-seeking Gamblers”
or EGs) and gamblers denying gambling for excitement (“Non-excitement-seeking Gamblers” or NEGs). EGs were more likely than
NEGs to report alcohol use and abuse/dependence, any substance abuse/dependence, incarceration, large gambling wins and losses,
more frequent and varied gambling, and symptoms of pathological gambling (i.e., at-risk gambling). Together, these findings
indicate that EGs are more likely than NEGs to demonstrate problems in multiple areas characterized by impaired impulse control. 相似文献

Recent empirical studies have evaluated if modifying electronic gambling machine (EGM) structural features could encourage
safer gambling behaviors and decrease gambling-related problems. Several of these studies refer to Harm Reduction (HR), suggesting
that the HR paradigm is useful to design, implement and test the efficacy of various prevention and treatment programs applied
to EGM users. After reviewing the origins of HR and specifying its operational definition, this paper discusses the relevance
of the HR framework for the study of measures related to EGM use and gambling in general. Examples are given to illustrate
the arguments. The results show that HR has been over-inclusive in the field of gambling. A specific and operational definition
and application of the HR framework is required for HR to be useful for the advancement of research in the gambling field.

Although there has been much speculation about the possible links between gambling and crime rates, relevant quantitative
evidence has been practically non-existent in Australia to date. This paper reports the results of research that utilised
a model designed to investigate the potential relationship between electronic gaming machine expenditures and property (income-generating)
crime rates reported to police in local areas in South Australia in 2002–2003. The research found that the higher the expenditures
on gaming machines in a particular local area per adult, the higher the income-generating crime rate in that area. No such
relationship was found between gaming machine expenditure and non-income-generating crime rates. However, further research
is required before any policy-relevant conclusions can be drawn. 相似文献

This study aims to develop a greater understanding of age differences in savings outcomes within Individual Development Accounts (IDAs). Participant data from the American Dream Demonstration (ADD) are examined for age differences in accumulated net deposits, average monthly net deposits, and deposit frequency. ADDprogram data are examined for savings match rates, monthly savings targets, direct deposit, and hours of financial education offered. Results indicate that, on average, older IDA participants have better savings outcomes than younger participants. Findings from this study suggest that impoverished middleaged and older adults can save if provided an opportunity and incentives. However, success will depend on the characteristics of the programs. 相似文献

In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions. 相似文献

We consider the transport of containers through a fleet of ships. Each ship has a capacity constraint limiting the total number of containers it can carry and each ship visits a given set of ports following a predetermined route. Each container has a release date at its origination port, and a due date at its destination port. A container has a size 1 or size 2; size 1 represents a 1 TEU (20‐foot equivalent unit) and size 2 represents 2 TEUs. The delivery time of a container is defined as the time when the ship that carries the container arrives at its destination port. We consider the problem of minimizing the maximum tardiness over all containers. We consider three scenarios with regard to the routes of the ships, namely, the ships having (i) identical, (ii) nested, and (iii) arbitrary routes. For each scenario, we consider different settings for origination ports, release dates, sizes of containers, and number of ports; we determine the computational complexity of various cases. We also provide a simple heuristic for some cases, with its worst case analysis. Finally, we discuss the relationship of our problems with other scheduling problems that are known to be open. 相似文献

Just as there is no universal understanding of what constitutes Coaching, there are no generally accepted ethical standards within Coaching. Opinions as to ethics within Coaching spring largely from the various ??Schools?? which transmit Coaching methods. Coaches working with J. L. Moreno??s Psychodrama follow the ethical and philosophical outlook contained in the analysis of creativity, spontaneity, the ??Social Atom?? and in the method, process orientated ??Encounter?? as understood by Moreno and Buber. That which they have internalised as ethical maxim and the Encounter method, is also understood to be a fundamental intervention. 相似文献

This paper studies information aggregation in dynamic markets with a finite number of partially informed strategic traders. It shows that, for a broad class of securities, information in such markets always gets aggregated. Trading takes place in a bounded time interval, and in every equilibrium, as time approaches the end of the interval, the market price of a “separable” security converges in probability to its expected value conditional on the traders' pooled information. If the security is “non‐separable,” then there exists a common prior over the states of the world and an equilibrium such that information does not get aggregated. The class of separable securities includes, among others, Arrow–Debreu securities, whose value is 1 in one state of the world and 0 in all others, and “additive” securities, whose value can be interpreted as the sum of traders' signals. 相似文献
