This article investigates consumers’ perceptions of three types of sponsors that play a role in backing financially Canadian artistic and cultural organisations: government ministries (or departments), Crown corporations and private companies. In addition to the type of sponsor and the nature of the sponsorship (philanthropic or commercial), the perceived congruence between the sponsor and the sponsored event (strong as opposed to weak), and the form of arts and cultural events (high art versus popular art and performing arts versus heritage arts) are explored in an experimental setting combining within‐subjects and between‐subjects factors. The main hypothesis of this research was that consumers’ perceptions are not the same when it comes to the different kinds of sponsors that evolve in the cultural and art fields. As the researchers explored this issue, they observed that significant differences do exist. It is believed that the rich findings of this study will be useful to civil servants.  相似文献

In this article I contend that John Stuart Mill’s Utilitarianism has been widely misunderstood, and hence the importance of his philosophical project has been diminished. This misunderstanding arises primarily from misconceptions regarding Mill’s definition of pleasure. However, these misconceptions may be successfully resolved by reflecting on Mill’s educational roots and his commitment to Greco-Roman philosophy. In particular, I hold that a deeper understanding of Mill’s philosophical progenitors (i.e., Aristotle and Epicurus) would lead us to conclude that for Mill the “pleasures” of the Utilitarian project are in the final analysis nothing other than the “pleasures” of the mind and conscience. Thus, by following Mill’s line of reasoning and adhering to some of the salient points of his work, specifically in Chapter 2 of Utilitarianism, we may reach a richer and more nuanced understanding of his impressive philosophical project.  相似文献

We present the results of a technological and morphometric analysis of all the Still Bay points (n = 371) recovered from the 1993 to 2004 excavations at Blombos Cave. We have been able to reconstruct the manufacturing sequence of the bifacial points from initial shaping, by direct internal percussion, to finished morphology, by direct marginal percussion. Identifications of impact fractures and manufacturing breaks are based on comparisons with experimental and archaeological bifacial points of verified function, i.e. Paleoindian points from bison kill sites, replicates of Solutrean points mounted as spear-heads or arrowheads and shot into adult cattle, and experimental replication on local raw materials. Our analysis shows that: (a) only a minority of the points are finished forms, and that a large number of pieces are production failures, a situation known at bifacial point production sites of later ages; (b) morphometric and impact scar analyses should take into account this process and distinguish finished points from preforms and unfinished points; (c) there were at least three different kinds of raw material sources and that there is a marked increase in the frequencies of silcrete with respect to the M2 and M3 phases at Blombos; (d) three kinds of evidence prove that some of the points were hafted axially and used as spear tips; (e) production of bifacial points was a primary activity at the site but the hypothesis of intergroup exchange of Still Bay points cannot be sustained on the basis of present evidence; and (f) the Still Bay phase appears to initiate a trend to relatively rapid changes in specialized hunting weaponry and that this innovation is congruent with other innovations such as bone tools, shell beads and engraved ochre of the M1 and M2 phases at Blombos.  相似文献

The Loch of Clickimin, Shetland, is well known for its broch and associated monuments supposedly of the Bronze and Iron Ages, although the former date is disputed. Pollen, diatom and sedimentological investigations permit fresh insights into the landscape and economic impacts of those who constructed the monuments, reveal that the environs of the site experienced environmental change from Neolithic times onward and provide the first Holocene radiocarbon dates from the immediate locality. The broch-building period witnessed a continuation of pre-existing pastoral husbandry for which heather burning may have exacerbated the natural spread of blanket peat. Initially, no evidence was adduced for local arable activity in the present investigation, and this was thought to be consistent possibly with the low numbers of excavated querns and the absence of cereal macrofossil finds when compared with other Shetland broch sites. The application of ‘rapid scanning’ techniques, however, led to the discovery of a consistent cereal-type pollen representation from Bronze Age times onwards. The discrepancies between the palaeoenvironmental evidence and the environmental and palaeoeconomic inferences made by the excavator of the site are explored. Evidence is presented that both supports and contradicts previous assumptions surrounding an important archaeological site.  相似文献
