Are the Economies of Canada and the United States Integrated? Evidence from Cointegration Analysis

In recognition of his contributions to the development of the method of cointegration analysis for analyzing nonstationary time series, late Sir Clive William John Granger (September 4, 1934–May 27, 2009) was awarded the Nobel Memorial Prize in Economic Sciences in 2003. Since then, this method has become a dominant paradigm in empirical economic research. However, this method is not without critics. This article is one in a series to point out some inconsistent arguments used in the development of the method of cointegration analysis. To illustrate by example, we apply the method of time series cointegration analysis and present statistical evidence that supports the proposition that the economies of Canada and the United States are integrated. We conclude this article by laying out a foundation to formally criticize the method of cointegration analysis in subsequent research.     

The Structure,Genre, and Meaning of Psalm 129

Psalm 129 depicts the distress of the people in exile. The common understanding is that vv. 6-8 is a lament for the downfall of its present adversaries. This article proves that this is not the meaning of the second half of the Psalm. It contains no appeal to God for salvation or thanksgiving for an ameliorated situation. Verses 6-8 depict the transience of the peoples exilic existence. The psalmist likens the people to the roof-top grass that withers rapidly. The rooftop grass evokes the poverty and the landlessness of the people that compel them to utilize their rooftops to grow crops that yield so little that there is almost nothing to harvest. This situation stands in contrast to the divine blessing of the agriculture in the Land of Israel. The psalmist’s objective is to convey the harsh reality of the exile. He juxtaposes this situation against the much awaited future and against the abundant Divine blessing of the past.     

Dental Pathology,Trauma and Attrition in a Zambian Iron Age Sample: A Macroscopic and Radiographic Investigation

Using morphological and radiographic methods, we analysed the dentitions of 24 individuals from Ingombe Ilede and Isamu Pati Zambian Iron Age archaeological sites. In this study, we determined the frequency and distribution of attrition, pathological conditions and dental trauma. This research also presents the first view of dental health for an Iron Age population in southern Africa. In total, 482 teeth were available for this study with 287 teeth missing, where 50 of these were lost antemortem and one individual had an erupted supernumerary first mandibular incisor. With the use of radiography and morphology, 21.5% (104/482) of the analysed teeth had at least one pathological condition or evidence of dental trauma. Some interesting dental aspects found and discussed in this paper are linear enamel hypoplastic lesions, radicular resorption, periapical lesions, fractures, dental modification and carious lesions. Many of these features were diagnosed with radiography, and this was especially important for those found below the cemento‐enamel junction (p = 0.0202) that are less obvious with macroscopic investigation alone. Additionally, the quantity and direction of dental attrition was studied. There were observed sex differences with the direction of wear, likely representing a sex‐specific cultural practice of using teeth as tools. Overall, the results show that this sample suffered relatively little from dental problems, and many of those observed features were associated with the traumatic procedure of dental modification, whereas others were age and diet‐related. Additionally, with the use of radiography, rare dental fractures and other features were diagnosed; these results demonstrate the requirement for its application in dental studies on archaeological assemblages.

河南省旅游区划研究

科学的旅游区划是区域旅游业发展的基础。在进行旅游区划时，要考虑到：旅游资源优势及开发措施的相对一致性、自然地域与行政区划的相对完整性、旅游中心地与旅游活动完整性、主导因素分析(相似性)与综合分析(差异性)相结合等。根据旅游区划的目的和原则，依据河南省的旅游资源状况和旅游资源的优势，以根文化为主将河南省划分为6个分区，即：沿黄(三点一线)重点旅游区、豫北旅游区、以楚文化为主的豫西旅游区、以商文化为主的豫东旅游区、以茶文化为主的豫南旅游区、以三国文化为主的豫中旅游区。并对各分区提出了开发对策。     

区域旅游规划的创新思考

区域旅游规划在指导区域旅游产业发展中发挥着十分重要的作用,然而受各种因素的影响,区域旅游规划中的一些方面已经显得不合时宜,正面临着诸多挑战,存在着一些问题,这些都影响了区域旅游规划对地区旅游产业指导作用的发挥.因此,对区域旅游规划的创新研究显得迫在眉睫.本文分析了当前我国区域旅游规划存在的问题以及这些问题背后深层次的原因,并提出了区域旅游规划创新的一些具体建议.     

A case of short‐root anomaly in a female from medieval Istria

Dental examination of a young female skeleton from medieval Istria revealed very short‐roots of both maxillary central incisors. This developmental pathological condition is known in the literature as short‐root anomaly, occurring mostly in maxillary incisors. In affected teeth, the crown:root ratio is 1:1.6. Although the prevalence of this condition has been reported in modern populations, this appears to be the first documented case of the anomaly from the medieval period. Unfortunately, fragmentary preservation of the skeletal material prevents us from making a full diagnosis of possible aetiology. Copyright © 2006 John Wiley & Sons, Ltd.     

Impact of Roots and Rhizomes on Wetland Archaeology: A Review

The general premise for successful archaeological in situ preservation in wetlands is that raising the water table will ‘seal the grave’ by preventing oxygen from reaching the deposit. The present review reveals that this may not be the entire picture, as a change in habitat may introduce new plant species that can damage site stratigraphy and artefacts. However, reviews on the types and degree of damage caused by vegetation to archaeological remains preserved in situ in wetlands have hitherto only been sporadically treated in the literature. Thus, this paper provides an overview of the adverse effects that various plants species have on the preservation status of wetland archaeology.Disturbance, due to growth of roots and rhizomes of the surrounding soil is denoted contextual disturbance, whereas deterioration of archaeological remains per se acts by several root-related factors that may be spatially and temporally concomitant. In waterlogged anoxic environments, deterioration is mainly related to (i) preferential growth of roots/rhizomes due to nutrient uptake and lesser soil resistance, (ii) root etching due to organic acid exudates, (iii) microbial growth due to root release of oxygen and labile organic compounds, and/or (iv) precipitation of hydroxides due to root release of oxygen. For example, roots of some wetland plants, such as marsh horsetail (Equisetum palustre), have been documented to penetrate archaeological artefacts down to c. 2 m in waterlogged anoxic soils. Here, we demonstrate that cultural heritage site management may unintentionally introduce deep-rooted or exudate aggressive plants by invoking change in hydrological conditions. Moreover, the implementation of biomass energy utilization and agricultural root depth optimization on a worldwide basis stresses the need for more research within root and rhizome impact on archaeological remains in wetlands. In conclusion, the worst-case scenario may be in situ deterioration instead of preservation, and one essential threat to archaeological wetland sites is the impact of wetland vegetation.
