AbstractThis qualitative research examines the Ecuadorian homosexual subculture and determines how gender, images, texts, and objects are referred to consumption culture. The netnography method was used to collect data from Twitter conversations. Categorization and classification of the conversations showed how the information was created, the purpose of the message, and the target audience. Results reveal common subjects in relation to news, human rights, and gender equality. Subjects were conceptualized based on the consumption of information in social, cultural, and political environments. It was concluded that images, texts, and objects included in the conversations provide significant information about the homosexual subculture consumption behavior. 相似文献

Airport capacity constraints are increasingly challenging the growth of air traffic. At the same time, decision-making about airport capacity investments is extremely complex, involving trade-offs. This paper’s objective is to optimise a privately owned airport system’s capacity investment decision in a city under demand uncertainty. Next to the investment size, our real options model incorporates the timing of the investment, as well as the cost of congestion. The results reveal that the larger a city’s initial airport capacity, the smaller its investment will relatively be and the lower the occupancy rate threshold at which investment will take place. We also show that, in case of a higher demand growth combined with more demand uncertainty, the city will benefit from a significantly larger investment, but made later at a higher occupancy rate. In this case, cities with a small initial capacity will sometimes even more than double current capacity. Higher airport charges and an increase in non-aeronautical revenues both lead to a later investment in more capacity, due to the increased project attractiveness. An increase in congestion costs results in a larger investment made earlier, in order to eliminate delays. Airport operational cost and capacity holding cost increases both lead to smaller investments. 相似文献

The literature on open innovation (OI) is characterised by studies based both on large companies and small and medium-sized enterprises (SMEs). Among all, one of the less explored issues in SMEs is what impedes them to adopt OI. Thus, this paper has the threefold objective to identify which factors hinder the adoption of OI in SMEs, to investigate if different behaviours exist among SMEs in relation to these factors, and to understand if the same factors effectively influence the level of adoption of OI. Based on a survey on 157 Italian SMEs, we identified four main barriers (namely, ‘knowledge’, ‘collaboration’, ‘organisational’, and ‘financial and strategic’) and three profiles of firms, different in terms of innovativeness of the industries they belong to (knowledge intensive, medium-innovative, and less innovative) and hampering factors perceived (‘knowledge’, ‘financial and strategic’, and ‘collaboration’ and ‘organisational’ barriers). Moreover, we found that some of these factors effectively impede the adoption of the paradigm. 相似文献

浅析影响食品饮料中糖分检测的因素 总被引:1,自引:0,他引:1
糖类是食品饮料中的重要组成部分。糖类物质是食品工业的主要原料和辅助材料。食品饮料中的糖分的高低不仅影响产品的口感、风味,而且会影响到产品的保质期。因此,食品生产企业必须严格控制食品饮料中的糖分的高低并且能够有效地检测出它的含量。本文从食品饮料中糖分的检测方法出发,主要论述了食品饮料中微量糖分检测的技术要领及其检验中的关键步骤,以实用性强,检测结果准确可靠为宗旨。特别是对于加工低糖、"无糖"食品及干型、半干型葡萄酒、黄酒、果酒的企业来说,提供一种检测技术以指导企业的生产。 相似文献

Modern tools for cost-effective conservation reserve site planning require the planner to have information about spatial distributions of conservation costs and benefits. Climate change creates unprecedented uncertainty about future land values and species habitat ranges, such that conservation scientists cannot map costs and benefits with certainty anymore. This paper contributes to the literature on the economics of conservation in the face of climate change uncertainty. It advances a new method for using modern portfolio theory to choose lands to protect that yield total conservation returns with less uncertainty. It explores the implications for portfolio recommendations of variation in the correlations between ecological and land-value responses to climate change. It also tests the robustness of the method to shortcuts that might be taken to simplify analysis, identifying problems that arise if conservation costs are ignored in portfolio analysis and demonstrating when portfolio recommendations are sensitive to how ecological benefits are quantified. 相似文献

在外部审计师依赖内部审计功能的研究中,国内外学者认为环境因素会影响内部审计的规模和质量,进而影响外部审计师依赖内部审计的功能。不少学者认为内部审计作为管理培训的会计风险、内部审计资源的安排和调整所产生的固有风险等因素都会影响外部审计师依赖内部审计的程度。另有学者认为外部审计师依赖内部审计的功能主要受内部审计外包的调整、非审计服务和客户的压力、内部审计资源调整等因素的影响。在今后的研究中应着重考虑治理质量因素的相互作用对外部审计师的影响和内部审计资源的影响因素以及这些因素如何影响外部审计的可靠性等方面。 相似文献

The Internet of Things (IoTs) is widely considered as one of the most important infrastructures for promoting economic development and technological innovation. The purpose of this study is to find the key factors influencing IoT adoptions, specifically in Taiwan’s logistics industry. In this study adopts a model which is a hybrid of technology, organisation and environment (TOE) and the decision-making trial and evaluation laboratory method (DEMATEL) to evaluate the complex factors influencing the adoption of IoT. The study employs the TOE framework as a basis to develop a general evaluation framework, and the DEMATEL technique conceptualises a structural model and then identifies the causal relationships among factors through a cause-effect relationship diagram. Finally, we also divided the complex influencing factors into cause and effect groups to better clarify the causal relationships for decision-making, to ensure the efficiency of IoT adoption. 相似文献
