Advances in Morphometrics in Archaeobotany

ABSTRACT

Morphometric analysis offers an alternative or augmentation to traditional archaeobotanical methods to address differences within and between plant species and their remains, refining and enhancing taxonomic resolution. Morphometrics, the measurement of size and shape, and the multivariate statistical analysis of generated quantitative variables, have long played a major role in biological research, including plant taxonomy and systematics, although its application in archaeobotany is relatively recent. Over the last few decades, there has been an increasing interest in the use of morphometrics for analysing a varied range of archaeological plant materials (mainly seeds, pollen, phytoliths, and starch grains). In particular, morphometrics have contributed to the study of the domestication and spread of many cereals world-wide, as well as that of other taxa including legumes, underground storage organs (USO), and fruits (such as olives, grapes, and dates). This paper reviews current methodologies, recent applications, and advances in the use of morphometrics in archaeobotanical research, discusses its role in exploring major research questions, and suggests possible future directions for its use.     

Sanctions and tourism: effects,complexities and research

Abstract

Despite the growing use of sanctions as a post-Cold War foreign policy instrument, there is limited research on sanctions in a tourism context despite their substantial impact on destinations and tourist flows. Although there is significant research on sanctions in political science, international relations, economics, and public policy, very few studies explicitly examine the effect of sanctions on tourism. This study therefore examines the intricate geopolitical relationship between sanctions and tourism via a scoping review of relevant literature. Each of the four main types of sanctions that were identified: financial, sectoral, diplomatic and individual, have different implications for tourism at various scales. The findings show that tourism is profoundly affected by sanctions impacting tourism and hospitality businesses and destination image, severely restricting international travel, and disrupting financial investment and supply chains. More comprehensive sanctions may lead to substantial economic and personal hardship in destinations as well as indirect effects including decline in the value of currency and inflationary pressures. Nevertheless, despite the development of smart and targeted sanctions they rarely affect the coercive capacity of the targeted government and induce political behavioural change. Resistive economies can develop in response to sanctions in which domestic tourism assumes greater significance as a result of reductions in international mobility. Some destinations facing sanctions also focus on specific international markets from non-sanctioning countries as well as a country’s diaspora. Overall, the study of sanctions deepens knowledge of the interrelationships between geopolitics, foreign policy and tourism and its ramifications for destinations. Significant gaps in knowledge for future research include the role of domestic politics in influencing sanctions policy, the selection of tourism as a specific target for sanctions, and the development of destination adaptation strategies to sanctions.     

“认知—情感—整体”三维视角下的遗产旅游地形象感知研究——以湘江古镇群为例

以湘江古镇群互联网旅游数据为研究对象，采用文本分析、主题分析和情感分析等方法，借助旅游地形象“认知—情感—整体”三维模型对遗产旅游地形象感知进行了探索。结果表明：①游客对湘江古镇群的认知形象以自然、场所/地域和活动为主，非物质形态记忆重心由饮食文化向历史文化偏移，环境生态记忆由模糊山水环境生态向具象历史文化空间记忆发展。②游客对古镇旅游设施与饮食文化积极感知最为强烈，影响湘江古镇群的消极情感形象最为重要的因素是门票价格贵、性价比不高等。③游客对湘江古镇群推荐与重游意愿普遍偏低，整体情感呈负性与正性情绪两极分化，正性情绪占比较高。     

How ‘creative’ is remembering? Culture-led regeneration and the politics of memory in Bogota,Colombia

ABSTRACT

Recently, Colombia’s post-conflict transition has experienced strong international attention. In Bogota, commemorative politics of the conflict insert themselves in complex processes of place branding: employing culture to rescale the city image from unsafe and violent to culturally vibrant. However, how to reckon with the country’s violent past in the culture-led renaissance of Bogota? Based on the author’s four-month of in-depth qualitative fieldwork on the main street Avenida 26 – at the center of both branding strategies and politics of memory – this paper shows the failure of institutional efforts to promote a brand of Bogota as a ‘City of Memory’. Socio-political divisions over the interpretations of the country’s past result in multi-scalar conflictive negotiations between politics and practices on the street: they reveal the tight link between memory, social justice, and urban segregation while denouncing the exclusionary visions of citizenship bared in political efforts to display memory as a territorial mark.     

Digital cementum luminance analysis (DCLA): a tool for the analysis of climatic and seasonal signals in dental cementum

Cementum banding patterns have been used by archaeozoologists and wildlife managers for a number of decades to assess the season and age at death of mammalian populations. However, the observation and measurement of the nature of cementum banding, especially that of the final band, has proved to be difficult except under conditions of excellent preservation and advanced microscopy. The research presented here details a method for extracting luminance data from the banding patterns of cementum in order to quantify the optical properties of cementum tissue. By doing so, analysis of the relationship between cementum deposition and environmental variables is achieved. We present the results of a digital cementum luminance analysis (DCLA) on a sample of first molars from two species, Ovis aries, Soay and Capra ibex. The results indicate that significant relationships occur between seasonal temperature changes and cementum histology. Furthermore, we show that luminance values can be used to assess the geographical range of genetically similar populations. Our results demonstrate that the study of luminance is a vital tool for the quantitative study of dental cementum for both archaeological and ecological studies.
