Estimation of investment costs in fish processing plants

Investment costs for fish processing plants are hereby presented along with a detailed analysis of different types of processes in relation to economies of scale.The cost-capacity factor for fish industry is estimated as 0.84, except for fish meal plants where the cost-capacity factor is 0.61.It is also discussed how technology, capacity and location in developed and developing countries can affect investment costs for fish processing plants, while cost-capacity factors remain unchanged.The concept of minimum limit for industrial capacity is included. Investment costs for minimum size plants or plants below minimum size are even greater than what would correspond to the correlation line. This is due to the need to incorporate one or more oversized pieces of equipment.

中国精英对中欧关系现状和前景看法

2010年5月至8月,在欧盟第七框架项目解析中国人对欧盟的看法的资助下,中国社会科学院研究生院联合中国人民大学等机构针对中国精英就中欧关系现状和前景及与此相关的问题看法进行了调查。调查数据显示:第一,精英对欧盟的知晓率比较低。第二,在信息渠道选择上,互联网、电视和报纸是三大主要工具,不同工具对中欧关系看法具有一定的影响。第三,中国精英对欧盟保持较好的印象。第四,精英认为欧盟的国际政治和经济影响力仅次于美国,且均强于中国。第五,精英对中欧关系现状和前景的看法日趋谨慎和保守。第六,通过回归分析可以发现,教育、收入、学习和工作经历等变量对精英的欧洲观有着明显影响。第七,学者和媒体工作者对中欧关系的现状和前景的看法和评价,均比其他群体更为积极和乐观。     

当前物价运行及其未来发展趋势

2011年8月以来,CPI同比涨幅持续回落,全年CPI上涨5．4％。从2012年物价走势看,受政策滞后效应和上年同期基数效应影响,上半年物价有望延续回落趋势,而随着政策微调和宏观经济回升,下半年物价重拾升势的可能性较大。预计2012年全年CPI涨幅为3．6％左右。综合考虑我国工业化发展阶段、刘易斯拐点与资源品价格市场化改革等因素来看,中长期内物价仍存在上涨压力。     

Consumer value of virtual music festivals

Virtual music festivals (VMFs) are a great opportunity for the music industry to improve high quality digital events; as an alternative consumption phenomenon, VMFs can reach hybrid audiences and help in the challenge of digitalization. This study aims to investigate the multidimensional structure of consumer value in VMFs (intra-variable perspective), as well as the effects of value on cognitive versus affective satisfaction and loyalty (inter-variable perspective). Using a qualitative–quantitative approach—focus group and survey with festival attendees (n = 246)—, a value structure of VMF is tested with partial least square–SEM as a reflective-formative-formative third-order model. Benefits and sacrifices are second-order constructs, while five positives (escape, novelty, enjoyment, musical content, and socialization) and two negatives (monetary and nonmonetary costs) are first-order ones. Results show VMFs value as a multidimensional trade-off, where socialization is not contributing to value, but a balance between cognitive (musical content) and affective (enjoyment, and less escape and novelty) exists. Furthermore, consumer value intensifies both cognitive and affective satisfaction, but just the former affects loyalty. These findings provide new insights to better understand the decision-making processes of virtual festival attendees.     

Tourist accommodation,consumption and platforms

The expansion of mediated accommodation on peer to peer (P2P) platforms, such as Airbnb, has generated extensive economic impact and structural changes in all the destinations involved. This study proposes an innovative analysis which estimates the economic impact associated with the expenditure of tourists staying in traditional hotel establishments in comparison to the impact of those staying in tourist housing mediated through P2P platforms. This research analyses fieldwork based on 1343 surveys carried out in the city of Granada, one of the main tourist destinations in Spain. Through the application of the input–output methodology we found that tourists staying in tourist housing mediated through P2P platforms generate a greater impact as a consequence of longer average stays and more heterogeneously distributed consumption. Their average expenditure is similar to that of tourists in hotels, but the indirect impact generated is greater. Consequently, we can better comprehend the economic impact associated with these platforms and their real effect. Public planners have to consider this information as part of the regulation and restriction of this activity.
