THE FOOD VALUE CHAIN AS A LOCUS FOR (DIS)AGREEMENT: CONVENTIONS AND QUALITIES IN THE SPANISH WINE AND NORWEGIAN SALTED COD INDUSTRIES

According to the theory of conventions, food value chains (FVCs) involve a complex array of actors who share an agreement about the qualities embodied in their particular foodstuff. Nevertheless, that agreement is continuously challenged by changes in consumer markets. Therefore, I argue that FVCs able to adapt those qualities to new trends will perform better than FVCs whose commitment to certain qualities leads to a misunderstanding between producers and consumers. The organization of the chain itself, the values of national regulatory frameworks, and the goals of the national innovation system are discussed as factors that shape an FVCs' ability to re‐arrange that core agreement. By using professional reports, statistical records and personal interviews, this article focuses on two FVCs that have experienced contrasting trajectories in recent decades in the Spanish market: the wine industry located in the region of Castile and Leon (Spain) and the Norwegian salted cod industry. The growing wine FVC has achieved a successful agreement about a set of qualities linked to nature, tradition, and place, all of them guaranteed by the reputation of the Designation of Origin (DO) system. In contrast, the salted cod FVC is losing its market share because its main actors are failing to properly communicate the key qualities of environmental sustainability and artisanal cod production to concerned Spanish consumers, as well as in the adoption of the place‐related attributes that still shape consumer preferences in Spain.     

Palaeoenvironmental significance of grain-size distribution of river flood deposits: a study of the archaeological sites of the Apengjiang River Drainage,upper Yangtze region,Chongqing, China

The grain-size distribution (based on cumulative probability curves) in the sediments produced by potential palaeofloods at the Shiniusi archaeological site is similar to that of modern flood sediments from the Wujiang River Drainage in the upper Yangtze River. There is an obvious pattern in the curves, with two segments, and the mean grain size (Mz), standard deviations (σ1), skewness, and kurtosis are all similar. Combined with the AMS¹⁴C dating data and the ages judged based on the presence of cultural remains, our data suggests frequent palaeoflood events within the Wujiang River Drainage. We hypothesize the existence of seven high flood possibility layers in the QST4 unit from Shiniusi archaeological site: during the periods of the Ming Dynasty (1368–1644 AD) to the Qing Dynasty (1616–1911 AD), and the end of the Eastern Zhou Dynasty (770 BC–256 BC) to the Shang Dynasty (1600–1100 BC). We also hypothesize ten high flood probability layers in the QST2 unit from Shiniusi archaeological site: during the periods of the Ming Dynasty to the Qing Dynasty, the periods of Song Dynasty (960–1279 AD) to the Yuan Dynasty (1206–1368 AD), as well as during the Han Dynasty (207 BC–220 AD) to the Eastern Zhou Dynasty (770 BC–256 BC). These results are consistent with palaeoflood events inferred from pollen and spore analysis and from historical records in other rivers.     

耕夫诗词钞

·2008·冬季号中国土族枸杞为报三春暖,精诚结渥丹。莫嫌身带刺,不许野禽餐。瀑布源出千重岭,流飞百丈崖。崎岖浑不顾,逐浪到天涯。丁亥七夕,日前闻凤凰桥垮塌云堆银汉畔,牛女共心焦。但恐烟岚重,摧坍喜鹊桥。登湟源南古城扼襟雄镇地,故垒势峥嵘。风咽闻羌笛,云舒展汉旌。峡衔     

中国古建筑中几种石灰类材料的物理力学特性研究

为探讨适宜于岩土文物保护加固的石灰类材料,对中国古建筑中几种石灰类材料及欧洲水硬石灰的化学组成和物理力学特性进行对比研究。研究表明烧料礓石、烧阿嘎土、欧洲水硬石灰NHL5及改性捶灰的化学组成主要是气硬性胶凝材料石灰CaO(或Ca(OH)2)和水硬性胶凝材料β-硅酸钙(β-CS)及铝硅酸钙(CAS),并且这些材料的结石体具有大的孔隙率及非常小的收缩变形性等特点,适宜于岩土文物的保护加固。除此之外,石灰、糯米灰浆、蛎灰、传统捶灰的主要化学组成为石灰CaO(或Ca(OH)2),实验研究结果显示,浆液的凝固速度慢,弹性波速小且上升速率慢,结石体虽然孔隙率大,但强度在短期内较低,易产生收缩变形,不适宜用于短时间内有强度要求的岩土文物保护加固,所以有必要对蛎灰和传统捶灰做进一步的改性研究,以便更广泛地应用于岩土文物的保护加固中。     

地方依恋元素和强度分析——基于青年游客的质性研究

地方依恋是个体与特定地方之间形成的情感关联.本文从旅游体验的视角,以青年游客为例,通过图片对地方依恋的有形展示和游客对图片背后独特故事和意义的讲述,分析了游客的地方依恋元素的构成,探讨地方依恋强度的递进演变以及特征.研究表明：（1）游客地方依恋元素包括背景元素和符号元素两类,背景元素体现地方氛围情境,符号元素凸显象征意义;（2）游客的地方依恋存在强度差异,由低到高依次为基于工具性依附的地方依赖、基于情感性依附的地方认同和基于精神性依附的根情结;（3）根情结的形成既源于游客多次对旅游地的深度涉入,在时间序列上由最初的地方依赖,到地方认同,再演变形成根情结,也可能源于游客出游前的信息积累和媒介影响.     

Attitude of Iranian Female University Students to Sport and Exercise

Women's sport has always been a challenging subject in Muslim countries and Muslim women have had to face various constraints regarding their participation in sport and exercise, which also influence their attitudes to sport. This study aims to explore the attitude of Iranian female university students toward sport by survey method (N?=?1,120) and qualitative interviews (N?=?50). The results indicate that the majority of the participants have negative attitudes to sport, and accordingly they do not practice it. Various macro-, meso- and micro-level factors were found as perceived barriers. From the results it can be concluded that the media as a tool for raising awareness to providing role models and shaping the social values of mainstream society does not take a positive role in order to develop the culture of women's sport, and to change the attitude of female students and their social environments to sport in Iranian society.     

An Evaluation of Endogenous Sustainable Development Planning for the Rural–Urban Environment in Gran Canaria

Urban developments can transform adjacent rural areas by degrading their natural resource base and environmental values. In this paper we provide evidence on the implementation of an endogenous sustainable development plan for the rural–urban environment in the city of Las Palmas de Gran Canaria. The objective was the generation of endogenous development in the rural areas by implicating the local population in developing activities in line with natural values and the recuperation of traditional cultures. At the same time, urban societies were expected to benefit from the preservation and availability of these rural environments. The plan was implemented in a large rural valley located between adjacent urban areas. The valley represents an opportunity for urban dwellers to benefit from a large rural park in the urban environment for leisure and cultural activities. The overall accomplishment of the plan was evaluated and contrasted with the benefits to the urban population, which were also measured with a discrete choice experiment. The results highlight that the principal objectives failed because of the lack of political determination to promote the participatory channels that would lead to the preservation of natural resources in a dynamic process of social change.
