Detecting Cultural Remains in Boreal Forests in Sweden Using Airborne Laser Scanning Data of Different Resolutions

ABSTRACT

Airborne laser scanning (ALS) is increasingly being used to detect cultural remains in forest landscapes. Boreal forests are challenging, however, since most ancient land use was carried out without major permanent ground disturbances. If this challenge can be met, there is a large potential for surveys through existing nation-wide laser-scanning programs, although their resolutions tend to be low. In this study, we compare the performance of low-resolution (LR) and high-resolution (HR) ALS data in the Krycklan catchment in northern Sweden, an area where ancient land use was small-scale and diverse. About three times as many cultural remains were detected in the HR data set, but the LR set was satisfactory for distinct structures. We analyze how LR data sets can be enhanced at ground-point classification and terrain-model generation and conclude that ALS data have a large potential for the detection and protection of cultural remains in the boreal forest.     

Enhancing field research methods with mobile survey technology

This paper assesses the experience of undergraduate students using mobile devices and a commercial application, iSurvey, to conduct a neighborhood survey. Mobile devices offer benefits for enhancing student learning and engagement. This field exercise created the opportunity for classroom discussions on the practicalities of urban research, the survey data was available for immediate analysis, and students felt they were conducting meaningful research. The module experience supports recent research finding that mobile devices offer significant benefits for instructors, but using mobile devices also creates potential risks (to the students, equipment, and data) that must be considered while planning modules and during instruction.     

Turkey's Bid for European Union Membership: Between "Thick" and "Thin" Conceptions of Europe

A team of Central Europe-based political geographers examines Turkey's bid for European Union (EU) membership, one of the most controversial issues confronting that country's and EU politics. The authors analyze Eurobarometer public opinion survey data on EU enlargement (and particularly Turkey's EU membership) across the 27 polities of the enlarged EU as well as in Turkey itself. The analysis of the data points to clear regional differences in support for Turkey's EU membership. Moreover, the authors' statistical analysis indicates two major components around which public perceptions of Turkey's EU membership coalesce. The first, identified as a "thick" component, based on the idea that EUrope embodies a specific cultural identity, opposes Turkish membership, whereas a second "thin" component, comprised of institutional-procedural norms, leaves the door open to Turkey. They argue that it is at the complex intersection of these two opposing views that Turkey's bid for EU membership should be located and eventually decided.     

The 2012 TRIP survey of international relations in Australia: one problem to rule us all

This article analyses the results of the most recent and largest cross-national survey on the international relations discipline. Completed by scholars in 20 countries, the survey covered the areas of teaching, research, foreign policy, the profession, and the relationship between policy and academia. From an Australian perspective, the key findings include the strong link between what academics teach and research; the narrowing epistemological gap between the USA and Australia; the curious pessimism of scholars on a wide range of foreign policy issues; and the ability of scholars to define research quality independently of other national settings. The most significant and alarming finding, however, concerned how the present structure of the field is undermining scholars'attempt to forge closer, more influential ties with policy makers in Canberra. In fact, it is clear from the results that what academics research and how they go about it is actually counterintuitive to this goal. The article concludes with three recommendations aimed at rectifying this problem.     

LOOKING BEYOND UNIVERSAL PRIMARY EDUCATION

This paper addresses gender equity in parents' educational investments in children in rural Bangladesh. The authors analyse correlates of time spent in school, studying outside school and work, using a dataset on time-use patterns of school-going children. The authors find that time spent at work varies inversely with the amount of time spent studying at home. Time spent in school is insensitive to factors such as poverty and gender. Time spent studying outside school is strongly influenced by household decisions that favour boys, who appear to have about 30 minutes more discretionary study time than girls.     

建国后30年浙江农村义务教育的历史考察——以农村民办小学为例

从1950年代到1970年代,浙江农村义务教育经历了由萌芽、发展到兴盛的过程。与此同时,浙江农村民办小学则伴随着浙江农村合作化及人民公社化运动经历了由萌芽、发展到逐渐消亡的过程。一兴一衰,成为共和国历史的最好注脚。当前,中国农村义务教育仍未能摆脱其弱势地位。对建国后30年浙江农村义务教育的历史考察,有助于我们建立一种更公正、合理的教育机制,以提升"境况最差的成员"的生命质量。     

Rose de Freycinet and the French Exploration Corvette L'Uranie (1820): a Highlight of the 'French Connection' with the 'Great Southland'

Rose de Freycinet, the first woman to record her circumnavigation of the globe, was shipwrecked in the Falkland Islands in the closing stages of her three-year voyage. The significance of her account is slowly becoming widely recognised, rendering the archaeological remains at the wreck of her transport the corvette L'Uranie and the survivors' camp ashore of growing international importance. In March 2001 a team under the auspices of the Western Australian Maritime Museum conducted research, search and survey aimed at adding to the body of knowledge about the de Freycinets, their ship and their camp. This is a précis of their results.

和龙市柳洞旧石器地点发现的石制品研究

2002年5月,吉林大学边疆考古研究中心在图们江流域进行考古调查时发现和龙市柳市洞旧石器地点。石制品分布在高出河水面20米的二级阶地上,共获得石制品89件,有石核、石片、石叶、细石叶、刮削器、雕刻器等。该地点的石制品特征可代表该流域的一种工业类型,与周边地区的旧石器有着密切的联系。该地点的地质年代应相当于晚更新世的晚期,旧石器时代的晚期。     

Fishing-gear sinkers recovered from an underwater wreckage site, off the Carmel coast, Israel

A classification scheme for the large number of fishing-gear sinkers recovered along the Israeli coast is devised. Sinkers, or weights, of lead and stone are classified by material, shape and method of manufacture.     

用微探针型EDXRF技术研究南宋官窑瓷片的化学组成及其含义

本文报道了用ENGLE-Ⅱ微探针能量色散型X荧光光谱（EDXRF）技术测定一批青瓷残片中的16种元素氧化物的含量．其残片来自浙江杭州地区南宋的郊坛窑和老虎洞窑。由主量元素判别方程。值表明,郊坛和老虎洞青釉瓷均属官窑制品,与龙泉民窑产品有很大差别。从主成分统计分析看出．郊坛下官窑与老虎洞官窑的瓷釉成分有明显不同,但其胎质成分的分布却有部分的重叠。这显示两类同属官窑的制品,其釉料可有不同的矿物组合。但胎料有时会交流使用。从釉层、中间层、和胎层的Al2O3和CaO的含量变化数据表明,郊坛下官窑和老虎洞官窑的青瓷制品有厚度分别为120-140um和230-240μm的中间层,反映出烧造工艺上有一定的差别。化学成分鉴定证实了考古工作者认为老虎洞窑实为史书记载的修内司官窑的观点．
