Abstract. The third national land survey is based on the orthophotos products. Only by providing 1:10000 orthophoto products that meet the quality requirements can the third national land survey be carried out smoothly, and the third national land survey products can be guaranteed to be accurate and reliable. Positional accuracy as an important quality element of 1:10000 orthophoto products is a key factor affecting the quality of 1:10000 orthophoto products, and directly affects the quality of the third national land survey products.This paper introduces the content of the positional accuracy quality inspection in the 1:10000 orthophoto products of the third national land survey.The mean square error in plane position and the image edge match are two important test entries in the quality control of positional accuracy . The paper specifically elaborates on the quality control of the above two important test entries. The quality control indexes of mean square error in plane position and the image edge match are introduced in detail, and the quality inspection method and quality evaluation method of position accuracy are proposed. And, the main quality problems found in the positional accuracy checking are illustrated by way of case analysis. At the same time, the cause analysis was carried out for these specific quality problems, and corresponding improvement suggestions were also proposed.This paper provides technical support and reference for the quality inspection of 1:10000 orthophoto products, and also has some positive effects on quality improvement.

Which kind of relation exists between a stone, a cloud, a dog, and a human? Is nature made of distinct domains and layers or does it form a vast unity from which all beings emerge? Refusing at once a reductionist, physicalist approach as well as a vitalistic one, Whitehead affirms that « everything is a society » This chapter consequently questions the status of different domains which together compose nature by employing the concept of society. The first part traces the history of this notion notably with reference to the two thinkers fundamental to Whitehead: Leibniz and Locke; the second part defines the temporal and spatial relations of societies; and the third explores the differences between physical, biological, and psychical forms of existence as well as their respective ways of relating to environments. The chapter thus tackles the status of nature and its domains.

The story of Lot is one of many shared by the Qur'an and the Torah, and Lot's offer of his two daughters to his people is presented in a similar way in the two books. This article compares the status of Lot in the Qur'an and Torah, and explores the moral dimensions of his character, and what scholars of the two religions make of this story. The significance of the episodes in which Lot offers his daughters to his people lies in the similarities and differences of the accounts given in the two books and the fact that, in both the past and the present, this story has presented moral problems and criticism has been leveled at Lot. Context is crucial in understanding this story, and exploration of the ways in which Lot and his people are presented is also useful in terms of comparative studies of the two scriptures. This article is divided into three sections: the first explores the depiction of Lot in the two texts, the second explores his moral limitations, and the third discusses the interpretations of various exegetes and scholars of the two books. Although there are similarities between the Qur'anic and Talmudic accounts of this episode, it is read differently by scholars from the two religions because of the different contexts of the respective accounts.

Key Issues

This chapter discusses the key issues surrounding Perpetua’s life and her narrative, the Passio Sanctarum Perpetuae et Felicitatis. It introduces the most perplexing circumstances around her life and times: the authorship of her Passio (which is written in at least three different hands); her life and family; the conditions of her martyrdom and of martyrdoms during the pre-Constantinian period; the status of martyrdom texts as personal, social, or historical documents; whether persecutions can be historically verified or were exaggerated by the Christians and others; and the afterlife of Perpetua and her text in writers from the third century to contemporary times. The introduction lays out the arguments for these thorny issues and tries to find a reasonable position on each one.

Land degradation is a global negative environmental process that causes the decline in the productivity of land resources’ capacity to perform their functions. Though soil and water conservation (SWC) technologies have been adopted in Geshy subcatchment, their effects on soil quality were limitedly studied. The study was conducted to evaluate the effects SWC measures on soil quality indicators in Geshy subcatchment, Gojeb River Catchment, Ethiopia. A total of 54 soil samples (two treatments–farmlands with and without SWC measures ∗ three slope classes ∗ three terrace positions ∗ three replications) were collected at a depth of 20 cm. Statistical differences in soil quality indicators were analyzed using multivariate analysis of variance (ANOVA) following the general linear model procedure of SPSS Version 20.0 for Windows. Means that exhibited significant differences were compared using Tukey’s honest significance difference at 5% probability level. The studied soils are characterized by low bulk density, slightly acidic with clay and clay loam texture. The results revealed that farmlands with SWC measures had significantly improved soil physical (silt and clay fractions, and volumetric soil water content (VSWC)) and chemical (pH, SOC, TN, C : N ratio, and Av. phosphorus) quality indicators as compared with farmlands without SWC measures. The significantly higher VSWC, clay, SOC, TN, C : N ratio, and Av. P at the bottom slope classes and terrace positions could be attributed to the erosion reduction and deposition effects of SWC measures. Generally, the status of the studied soils is low in SOC contents, TN, C : N ratio, and Av. P (deficient). Thus, integral use of both physical and biological SWC options and agronomic interventions would have paramount importance in improving soil quality for better agricultural production and productivity.

AbstractIncreased economic integration throughout the world, the growing dominance of foreign affiliate production over international exports, the routinization of innovation, and amplified knowledge-intensiveness of FDI collectively characterize the new global economic environment in which SADC nations are attempting to develop and compete. This paper provides a detailed summary of the global economic context and one of its leading engines, namely, science and technology (S&T). Analysis of Africa's post-independence S&T travails and successes constitutes the second section of the paper. Various factors that have collectively arrested S&T growth are discussed. The third and largest section is the analysis of commonalities and particularities of S&T needs and activities by the SADC secretariat and member states. Focused analytical reports on the status of S&T development efforts in Botswana and Zimbabwe comprise the final section. Based on the contextual threats and opportunities discussed above, the paper concludes with two concrete recommendations: integrating and adopting the elements suggested in the paper for a long-term S&T development model, and pursuing state-sponsored or quasi-state-sponsored reverse engineering campaigns.

At the beginning of 1995, nearly two million Turkish nationals were living in Germany. While this represents only about 2.5% of the total population, the Turkish minority significantly influences German politics. As the single largest group of “foreigners” living in Germany, the Turkish population is a prime target of rightwing violence. Questions regarding Turkish rights to residency, work permits, and citizenship are controversial domestic political issues and their presence affects international relations between Germany and Turkey. This article examines the Turkish diaspora in Germany and its implications for Germany’s domestic and international politics. The first section identifies the status of the Turks living in Germany. The second traces the growth of the Turkish population in Germany. The third evaluates the domestic political and economic effects that the Turkish presence engenders, as well as prospects for assimilation. The fourth section identifies ways that international relations are influenced by the Turkish minority in Germany.
