The presented paper is dedicated to a new ret-rospective view on the history of natural sci-ences in XX-XXI cc, partially including the sci-ence philosophy (mainly, the problems of the scientific realism, i.e. the correspondence of science to reality) and also a novel scheme for different classes of sciences with different ob-jects and paradigms. There are analyzed the chosen “great” and “grand” problems of phys-ics (including the comprehension of quantum mechanics, with a recently elaborated new chapter, connected with time as a quantum obs- ervable and time analysis of quantum processes) and also of natural sciences as a whole. The particular attention is paid to the interpretation questions and slightly to the aspects, inevitably connected with the world- views of the res- earchers (which do often constitute a part of the interpretation questions). 展开更多

In the mid-19th century, out of their dissatisfaction with the neglect of the economic theories about other countries’ experiences in the British classic economics, the economists in the German Historical School worked hard to construct an economic theory that was congruent to the developmental stage in their own country’s culture and history. Their deeply-cherished concern about the reality in a transitional era when Germany was approaching modernization drove them to propose that the living condition of the working class be improved by the power of the state. In the late 80’s of the same century, the Methodenstreit of German Historical School versus the Austrian School broke out, after which the mainstream economics was well on its way in terms of theoretical refinement and scrutiny, whereas the influence from the Historical School gradually subsided. Even so, the lessons from the Historical School are still enlightening to research in contemporary social sciences. This paper describes the unique basics in the theory building of the Historical School; explains the background and meaning of its academic origin, research methodology, and the Methodenstreit; and from there, discusses implications for contemporary social sciences. 展开更多

Hohoe is an area of intense and prolonged, seasonal malaria transmission. In 2006, malaria control programme activities which provided In-secticide Treated Bed-Nets (ITNs) to resident children under five years and Artemisinin Combination Therapies (ACTs) for the management of malaria were introduced into the Hohoe Municipality. Before the introduction of the control programme, baseline surveys were carried out in communities in the Hohoe municipality to determine the prevalence of malaria, fever, anaemia, malaria parasite density, gametocytaemia and ITN ownership and use in June and November 2006 ahead of the intervention programme. Similar surveys were conducted in 2010 after the intervention to assess changes in the earlier indicators in the same communities. This report presents an evaluation of the intervention by comparing findings before and after the malaria control interventions. Methods: In 2010, two community-based surveys were carried out in thirty communities among children aged five years and below. The first one was at the beginning of the rainy and high malaria transmission season in June and the other was in November at the end of the rainy season. The surveys were to determine the prevalence of malaria, fever, anaemia and ITN ownership, use and effectiveness among children less than 5 years. Data were collected in the form of interviews using questionnaire and collection of biological samples. Findings were compared to those similar surveys conducted in the same communities and age groups in 2006. Pr-testi was used to analyze two sample tests for proportions and t-test was used for means. Findings: Malaria prevalence decreased by 20% [9.0% vs. 7.2%;p = 0.0.40], fever decreased by 47.8% [2.3% vs. 1.2%;p = 0.008] and anaemia decreased by 32.9% [7.8% vs. 5.3%;p = 0.002]. ITN ownership increased by 67.9% [20.8% vs. 64.8%;p < 0.001], ITN use increased by 64.2% [15.1% vs. 42.2%;p < 0.001] and ITN effectiveness increased by 41.7% [20.0% vs. 34.3%;p < 0.001]. The proportion of children with high density parasitaemia reduced by 17.9% [2.8% vs. 2.3%;p = 0.223]. Gameto-cytaemia decreased by 82.5% [0.8% vs. 0.14%;p = 0.002. Similarly data comparing 2006 and 2010 post-rainy season showed that malaria prevalence decreased by 16.8% [40.4% vs. 33.6%;p < 0.001], fever decreased by 14% [5.0% vs. 4.3%;p = 0.347] and anaemia decreased by 64.2% [12% vs. 4.3%;p < 0.001]. The proportion of children with high density parasitaemia also reduced by 69.5% [10.5% vs. 3.2%;p < 0.001] and gametocytaemia decreased by 78.5% [0.8% vs. 0.17%;p = 0.008]. Conclusion: This study suggested that there was an association between the current intervention and reduction in the prevalence of malaria, fever and anaemia. High parasite density and gametocytaemia prevalence have also significantly reduced over the five years of the introduction of the control measures. There has also been a significant increase in the ownership and use of ITNs. 展开更多

The emergence of the middle class was closely related to the appearance of industrial society and its consequential constant changes in the social structure. Karl Marx and other theorists in the same camp were among the earliest scholars who discussed that topic. For a quite long period of time, the debate was mainly focused on the characteristics of the “new middle class.” The middle class, however, has undergone a categorical transformation from the old to the new middle-class, and furthermore, this transformation itself has signified the transition in social patterns from industrial to post-industrial society as well as economic globalization, both of which have contributed to the growth and global expansion of the middle class, having thus fundamentally renovated the middle class. 展开更多

Mari Bugti hills and surroundings belong to Sulaiman basin (fragment of Gondwana) lies under the territory of Balochistan, South Punjab and North Sindh (Pakistan) but luckily have diverse marine and terrestrial sediments varying in age from Triassic to Recent, petroleum and a large number of mineral resources especially huge gypsum and cement resources, numerous suitable anticlinal structures and world-famous paleontology. The large-sized poripuchian titanosaurs, theropods, mesoeucrocodiles, pterosaur, bird and snake were reported from the latest Cretaceous Vitakri Formation, and largest terrestrial mammals and eucrocodiles were reported from the Oligocene Chitarwata Formation and other mammals were also reported from Late Paleogene and Neogene terrestrial deposits. Previously part of this area was not mapped due to remoteness and security problems but recently the mapping of these areas was started. Further, the structural and geological maps of previously omitted parts are added here. After performing the multidisciplinary field investigations by senior author, the corresponding results were obtained. The main objective of this work is to focus on the lithostratigraphic deposits, structure, geological history, economic geology and paleontology of the Mari Bugti Hills and surrounding areas. 展开更多

This article takes Fu Chang's Precedents of Ritual Protocol for Jin's Imperial Ministers and Xun Chuo's Annotations to the Report on Jin's Official Posts as a means to observe the interactions between books and political processes during the Western and Eastern Jin dynasties. Both Fu Chang and Xun Chuo were employed as high-ranking officials, with a background of being from the Central Plain, by the regime of the Later Zhao founded by Shi Le. Their purpose for writing the two books was to provide guidance for the regime's institutional establishment. The collapse of Shi Le's regime led to the flow of people and their possessions to the south. During these movements, the two books along with other materials and records were brought to Jiankang and then contributed to the institutional and cultural development in the middle and late Eastern Jin Dynasty. As historical facts and references for political reformation, these books revealed the duality of institutional writings. The collection and dispersion of books after the Disaster of Yongjia, as well as the social and cultural changes, should be placed in a wider political process for further examination. 展开更多

API RP2AWSD is a design code in practice for design of jacket platforms in the Persian Gulf but is based on the Gulf of Mexico environmental condition. So for the sake of using this code for the Persian Gulf, it is better to perform a calibration based on this specific region. Analysis and design of jacket platforms based on API code are performed in a static manner and dynamic analysis is not recommended for such structures. Regarding the fact that the real behavior of the offshore jacket platforms is a dynamic behavior, so in this research, dynamic analysis for an offshore jacket platform in the Persian Gulf under extreme environmental condition is performed using random time domain method. Therefore, a new constructed offshore jacket platform in the Persian Gulf is selected and analyzed. Fifteen, 1-h storm, simulations for the water surface elevation is produced to capture the statistical properties of extreme sea condition. Time series of base shear and overturning moment are derived from both dynamic and static responses. By calculating the maximum dynamic amplification factor (DAF) from each simulation and fitting the collected data to Weibull distribution, the most probable maximum extreme (MPME) value for the DAF is achieved. Results show that a realistic value for DAF for this specific platform is 1.06, which is a notable value and is recommended to take into practice in design of fixed jacket platform in the Persian Gulf. 展开更多

The scholarship in modern China is closely related to Western sinology in terms of school ties.Gu Jiegang’s launching of the"Discussion of Ancient History"movement centered on the"theory of the accumulated creation of Chinese ancient history"was a representative example.At the beginning of the movement Hu Shi and Gu Jiegang proposed the notion that,"there was no history before the Eastern Zhou Dynasty"which was indebted to the historical skepticism by Philip Van Ness Myers(American scholar)and Friedrich Hirth(German sinologist)of the same period.The idea that"the Shang Dynasty is still in the late Stone Age"advocated by Hu and Gu was also directly influenced by J.G.Andersson’s An Early Chinese Culture.Conversely,American sinologist Arthur W.Hummel Sr played a key role in introducing and evaluating the first volume of Discussion of Ancient History to Western academia.Paradoxically,while Swedish sinologis Bernhard Karlgren wrote On the Authenticity and Nature of the Tso Chuan to refute Kang Youwei’s reinterpretation of Confucian Classics(The Forged Classics of the Wang Mang Period),his work however became of value for Chinese historic doubt scholars to reaffirm the value of New Text Confucianism and advance the"Discussion of Ancient History"movement.If we would like to choose a saying to describe the relationship between the"Discussion of Ancien History"movement and Western Sinology,the Chinese proverb,"Stones from other hills may serve to polish jade of this one,"may be an appropriate choice. 展开更多

In 1993,the World Bank released a global report on the efficacy of health promotion,introducing the disability-adjusted life years(DALY)as a novel indicator.The DALY,a composite metric incorporating temporal and qualitative data,is grounded in preferences regarding disability status.This review delineates the algorithm used to calculate the value of the proposed DALY synthetic indicator and elucidates key methodological challenges associated with its application.In contrast to the quality-adjusted life years approach,derived from multi-attribute utility theory,the DALY stands as an independent synthetic indicator that adopts the assumptions of the Time Trade Off utility technique to define Disability Weights.Claiming to rely on no mathematical or economic theory,DALY users appear to have exempted themselves from verifying whether this indicator meets the classical properties required of all indicators,notably content validity,reliability,specificity,and sensitivity.The DALY concept emerged primarily to facilitate comparisons of the health impacts of various diseases globally within the framework of the Global Burden of Disease initiative,leading to numerous publications in international literature.Despite widespread adoption,the DALY synthetic indicator has prompted significant methodological concerns since its inception,manifesting in inconsistent and non-reproducible results.Given the substantial diffusion of the DALY indicator and its critical role in health impact assessments,a reassessment is warranted.This reconsideration is imperative for enhancing the robustness and reliability of public health decisionmaking processes. 展开更多
