Dimension Of Sources Research Articles

Disinformation a problem for democracy: profiling and risks of consensus manipulation.

The aims of this article is to analyze in the post-pandemic era of technological wars how platformisation and the opacity that characterizes it can generate manipulative effects on the dynamics of consensus building. We are now in the era of the self-informative program; the hierarchical dimension of sources has vanished in parallel to the collapse of the authority, credibility, and trustworthiness of classical sources. Now, the user creates his own informative program, which gives rise to a new relationship between digital individuals. With this framework in mind, I intend to analyze the narrative of this post-pandemic phase proposed by mainstream media, using the tool of the fake news hexagon, to verify the impact and spread of fake news through social networks where emotionalism, hate speech, and polarization are accentuated. In fact, the definition of the fake news hexagon was the starting point to study through a predefined method the dynamics of proliferation of fake news to activate correct identification and blocking tools, in line with what is defined in the Digital Transformation Institute's manifesto. Platforms drive the process of identity construction within containers that adapt to the demands of individuals, leading toward a flattening out of results from web searches as these follow the principle of confirmation bias. We assist to an increasing lack of recognition of the other, the individual moves away from commitment, sacrifice, and achieving a higher collective good. It becomes quite evident how, in the face of the collapse of authority, as this new dimension takes hold, the understanding of reality and the construction of public identity can no longer be the result of the ability to decipher messages alone. Media and social multidimensionality necessitate developing new interpretive processes.

Relationship Between Quality of Life and Health Literacy in Patients with Sickle Cell Disease

Background: Disease management approach is an effective means in genetic disorders, such as sickle cell disease (SCD). This disease is a neglected chronic disease of increasing global health importance. In this process, acquiring knowledge and information related to the disease plays a critical role in self-efficacy and self-care. Therefore, one of the determinants of health and criteria for enhanced quality of life is health literacy. Objectives: Therefore, the present study aimed to determine the relationship between the quality of life and health literacy associated with disease management among patients with SCD. Methods: This descriptive-correlational study was conducted on 150 patients with SCD in Ahvaz. These patients have been referred to the thalassemia clinic and the thalassemia ward of Shahid Baghaei-2 Hospital and selected via accessible sampling. The study data were collected using WHOQOL-EREF-26 items and a researcher-made questionnaire about information resources whose reliability and validity were confirmed. Then, the data were entered into the SPSS software and analyzed via descriptive statistics, chi-square, regression, and correlation tests. Results: The mean age of the participants was 27.56 ± 9.14 years. The most important resource for increasing knowledge was the physician in 83.3% of the patients. In addition, they had acquired the highest amount of knowledge about the causes and symptoms of the disease. Moreover, the highest and lowest mean scores of quality of life were related to physical health (50.80 ± 9.94) and (45.23 ± 19.91) social health dimensions, respectively. The results showed statistically significant differences between the place of residence with the dimension of social health (P = 0.037, b = -11.05) and sources of knowledge enhancement with the dimension of social health quality of life (P = 0.010, b = -14.96). Conclusions: Since quality of life is a subjective and multifactorial concept, its effective factors have to be explored. The present study results indicated that the patients were eager to acquire knowledge about their disease. The higher the patients’ knowledge level, the higher their ability in disease management, self-care, and social health dimension of quality of life would be.

A Framework for Understanding the Institutional Arrangements of Urban Village Redevelopment Projects in China

Large-scale urban village redevelopment projects (UVRPs) have been implemented in different ways in China in recent years. This study develops an analytical framework for understanding the heterogeneity of institutional arrangements for UVRPs in China. The analytical framework is established from the perspective of neo-institutional economics. Decision-making and funding sources are used as two dimensions to classify the institutional arrangements into four categories: top-down with government funding (TGF), top-down with villager funding (TVF), bottom-up with villager funding (BVF) and bottom-up with private developer funding (BPDF). The comparative analysis reveals that the bottom-up institutional arrangement is generally more effective in political persuasion than the top-down one, especially when villagers’ committees (VCs) that are responsible for the project implementation are elected freely and fairly. When incorporating the dimension of funding sources into the analysis, a TVF institutional arrangement is likely to incur higher transaction costs than a TGF institutional arrangement, leading to the project having a longer duration. However, when private developers are allowed to participate and to develop UVRPs, the transaction costs will increase due to opportunism and information asymmetry. Policymakers should play an active role in arbitration as it would effectively mitigate the size of transaction costs used to deal with clashes between VCs, ordinary villagers and private developers. Based on information for 394 UVRPs collected from five coastal cities in Zhejiang province, the research findings reveal that a TVF institutional arrangement, which has the highest transaction costs, is still dominant in China. This may be the result of policy continuity and path dependence. Institutional change is contingent on the relative costs, which are the sum of the transformation costs and the transaction costs. Incremental institutional change, rather than radical institutional change, is more likely to occur in China.

Characterizing Subsurface Rectangular Tilted Heat Sources Using Inductive Thermography

In this study, we characterize the lateral dimension, depth, and inclination of buried tilted rectangular heat sources from time domain temperature data measured at the surface. The heat sources are representative for planar defects that emit heat in thermographic tests with internal burst excitation. We present a semi-analytical expression for the evolution of the surface temperature distribution. The emitted flux, dimensions and inclination of the heat source are determined by fitting the model to two perpendicular surface temperature profiles and the temperature history at one point of the surface. We show that the sensitivity of the data to the geometrical parameters of the heat source decreases as the angle it makes with the surface increases. The study also shows that the optimum duration of the excitation corresponds to a thermal diffusion length covering the distance from the surface to the deepest end of the heat source. The accuracy and precision of the results for different noise levels and inclinations have been tested by fitting the model to synthetic data with added noise. Fittings of experimental induction thermography data on 3D printed photo-polymeric resin samples containing calibrated Cu slabs confirm that it is possible to characterize tilted rectangular heat sources from surface temperature data.

Indo-European anthropological and cultural sources of the Ossetian heroic epic as an example of nomadism of ideas and values (problem statement)

The paper makes an attempt to analyse the Indo-European cultural categories in the dimension of anthropological and cultural sources which have constituted the national epic of Ossetians, the descendants of the legendary Sarmatian Alans. As a result of studying the present state of knowledge about nomadism, the authors propose a way of understanding that concept as an intercultural penetration of ideas and values through the cultural texts (myths, literary works) in the history of the Indo-European family of Eurasian nations. The authors present the nomadism of Indo-European cultural elements which emerge from the studies of Galina Bieliakowa on Slavic mythology. The article discusses the nomadism of Indo-European ideas, values and cultural symbolism in the context of contemporary anthropological and archaeological knowledge. The authors focus on the phenomenon of preserving the Indo-European cultural heritage in the mythology of the North Caucasus (e.g. the Ossetian heroic epic). The authors also show the phenomenon of the literary image of the sword as an archetypal symbol of honor and purity on the example of the nomadism of that cultural image from the Caucasian epic to the medieval knight epic.

POTENTIAL AND ECONOMIC DIMENSION OF RENEWABLE ENERGY SOURCES IN DIYARBAKIR

It is considerably difficult to achieve sustainable development nowadays because non-renewable energy sources are rapidly running out of reserves due to extensive consumption . For sustainable development, serious social and environmental policies should be constituted and implemented in harmony to reduce the minimum economic and social costs of development. From this point of view, energy sources are the main axis of these policies especially in the countries with limited reserves or dependent on foreign reserves in terms of high cost imposed on the country’s economy and also the damage to the environment. High population growth, migration waves, energy-intensive new investments, technological improvements, and excessive energy consumption habits increase the energy consumption. Countries are in constant search to avoid the negative effects that may arise in economic and social life due to future energy crisis. Therefore, countries have contemporarily inclined to renewable energy sources such as solar, wind, and water. In this study, the current established capacity of solar, hydraulic, biomass, wind and geothermal energy in Diyarbakir has been studied. It is aimed to introduce the potential and economic dimension of renewable energy sources, especially solar energy in Diyarbakir. Data in regional, national and international scale have been obtained and evaluated with its economic dimension.

Student-Teachers’ Perceptions of Second Language Teaching in the CBL Program: Identity Construction and Development

In recent times, researchers of second language learning have suggested that second language learning is not simply a cognitive or linguistic issue, but is also a social, political, and cultural one (e.g., Atkinson, 2002; Firth & Wagner, 1997; Larsen-Freeman, 2007). Research on student-teachers’ identity (e.g., Atkinson, 2004; Day & Kington, 2008; Wenger, 1998) also stresses the importance of identity development to help students with setting goals and learning (e.g., Olsen, 2008). Therefore, this qualitative research aimed to investigate STs’ identity development and how identity transfers knowledge to facilitate the learning and teaching processes. This study applied a two-semester community-based learning program involving 40 university students and 50 elementary school students in Taiwan. It was found that negotiating multiple discourses in diverse social contexts is another dimension of learning sources for student-teachers’ understanding of personal values, increasing the awareness of social responsibilities, and fashioning their personal and pedagogical identities.

High-resolution aeromagnetic survey of Calabria (Southern Italy)

ABSTRACTWe present a 1:350,000 high-resolution magnetic anomaly map of Calabria (Southern Italy), obtained by merging the results from two low-altitude aeromagnetic surveys performed in southern and northern Calabria. Magnetic anomalies of Calabria are of low intensity, and mostly range from 11 to –9 nT. Northern Calabria is characterized by positive anomalies in the Tyrrhenian margin (Coastal Chain) that turn into negative values moving eastward in the Sila Massif. Southern Calabria is characterized by slightly positive anomaly values, interrupted by a null magnetic anomaly corridor roughly corresponding to the eastern margin of the Gioia Tauro basin. Finally, anomaly values turn systematically negative in the Messina Straits. Due to the unprecedented resolution (low flying height, spatial sampling along the flight line of ∼5 m and 1–2 km flight line spacing), the new map highlights, in detail, the geometry and setting of the upper crustal features. As Calabria is one of the most seismically active regions in Italy, hit by several high-magnitude earthquakes in recent centuries, the interpretation of this new map will hopefully contribute to new insights into the crustal geological setting, location and dimension of the main seismogenic sources.

A methodology for acquisition and processing of thermal data acquired by UAVs: a test about subfluvial springs’ investigations

ABSTRACTAn accurate description of watercourses helps to easily understand their behaviour both for routine hydrological investigations and in disasters cases. Knowing the position and the dimension of the supply sources of the river is crucial, since they have a direct influence on its behaviour; however, they are not often easily identified, and almost always completely unknown. Aerial thermal data can be critical in order to rapidly reveal and map the river supply source points for extensive areas. Using unmanned aerial vehicles (UAVs) to collect very easily and quickly high-resolution information is thus very interesting. UAVs can house many sensors for performing investigations in different bands of the spectrum, including thermal data. This work explains how UAVs can be used to collect this kind of data (through RGB and thermal devices) and presents a strategy to easily integrate the information from these different sensors. Integration procedures, also applicable in emergency situations, were developed. These methods do not require points on the ground and can be performed using commercial devices.

Research on Analysis of Multi-source Data Fusion Model in Smart Classroom

Smart Classroom, as a new learning environment, is a new direction in the development of education informatization and has been a hot research in the field of educational technology in recent years. Its wisdom goal is based on the large amounts of data that produced by learners study in the learning process. And for the Smart Classroom, the fusion analysis of the data in the learning process can provide some advice for learners and teachers. At present, there is little study on multi‐source data fusion analysis. In view of this, this paper shows the research status of data fusion, and analyzes the Smart Classroom from the dimension of data sources and data fusion, then builds a process model of multi‐source data fusion analysis, finally applies it into practice from the dimension of data fusion.

Médicine, religion et société dans la Chine médiévale: Étude de manuscrits Chinois de Dunhuang et de Turfan (review)

margin. Perhaps Brill can consider publishing volume 1 in paperback as a service to the community of researchers not only in Chinese Studies, but also in the disciplinary fields of social history, comparative religion, ritual studies, and human geography.9 ADAM YUET CHAU University of Cambridge Médicine, religion et société dans la Chine médiévale: Étude de manuscrits Chinois de Dunhuang et de Turfan. Sous la direction de CATHERINE DESPEUX, avec la collaboration de ISABELLE ANG. Paris: Collège de France, Institute des Hautes Études Chinoises, 2010. 3 vols. 1386 pp. J140 (pb). ISBN 978-2-85757-068-6 In the first decade of the 20th century, Sir Aurel Stein first brought back over 10,000 manuscripts to the British Library, and Paul Pelliot, shortly afterwards and during the same years (1906–1908), sent over 6000 manuscripts from Dunhuang and Turfan to the Bibliothèque nationale. One could argue that a century of intermittent effort has gone into this volume from that beginning with their discoveries to the opening of the twenty-first century, when the international research group on the Dunhuang medical manuscripts collaborated (2001–2007) and published this magnum opus in 2010. The chief-editor Catherine Despeux’s introduction provides an illuminating overview of all the people, institutions, libraries, and places across the globe that have been involved in the remarkable story of these rare Chinese medical manuscripts over the past century. The 438 Chinese manuscripts discussed and indexed from every angle in these three volumes, dating from the seventh to the eleventh centuries, came from Dunhuang 敦煌 and Turfan 吐魯番 and deal with a range of health-related issues. They are scattered across sixteen libraries in six countries—China, Japan, England, France, Germany, and Russia. The first two volumes contain a total of fourteen chapters by nine scholars of specific manuscripts that reveal various dimensions of medicine, religion, and society in medieval China and which add much complexity to our understanding of the period and northwest China. The following list gives a sense of not only the range of themes these authors have explored but also of the richness of the 438 manuscripts they have explicated: medical institutions and therapies, medical recipes, life hygiene and longevity practices, and magico-religious Buddhist practices (Catherine Despeux); fragments of the Shanghan lun 傷寒論 and Wuzang lun 五藏論 and the literature on sexuality (Donald Harper); pulse diagnosis (Elisabeth Hsu); pharmacopoeias (Ute Engelhardt); moxibustion 9 If one is interested in reading more on scholarship related to these two volumes one can start with Kenneth Dean’s Lord of the Three in One: The Spread of a Cult in Southeast China; Zheng Zhenman’s book Family and Lineage Organization and Social Change in Ming-Qing Fujian, translated and introduced by Michael Szonyi (Honolulu: University of Hawai‘i Press, 2001); and Hugh R. Clark’s Portrait of a Community: Society, Culture, and the Structures of Kinship in the Mulan River Valley (Fujian) from the Late Tang through the Song (Hong Kong: Chinese University Press, 2007). 112 BOOK REVIEWS (Vivienne Lo); medicine and hemerology in calendars (Alain Arrault); Chinese-Hu [i.e. ‘‘barbarian’’] medical interactions and childhood illnesses and Buddhist demonology (Chen Ming 陳明); medical products, aromatics, and tinctures from the march to Turfan in 743 (Éric Trombert); and apocryphal sutras and illnesses (Fang Ling 方玲). The nine authors (including Despeux) and five collaborators have together produced the most important synthesis of Dunhuang and Turfan manuscripts since Marc Kalinowski’s Divination et societié dans la Chine médiévale (2003) and Christopher Cullen and Vivienne Lo’s Medieval Chinese Medicine: The Dunhuang Medical Manuscripts (2005).1 Developing further upon their predecessors’ scholarship, they collectively weave throughout the fourteen wide-ranging and in-depth articles the three thematic threads of medicine, religion, and society. Readers of the Journal of Chinese Religions will be most interested in the second of these thematic threads, on religion, which for the most part concentrates on what these manuscripts reveal about Buddhist institutions, practitioners, patrons, practices, and influences related to illness and healing in the Dunhuang and Turfan regions. This dimension of the primary sources and their analysis in these volumes makes an important contribution to the historical study of Chinese...

Envelope extraction based dimension reduction for independent component analysis in fault diagnosis of rolling element bearing

Abstract A robust feature extraction scheme for the rolling element bearing (REB) fault diagnosis is proposed by combining the envelope extraction and the independent component analysis (ICA). In the present approach, the envelope extraction is not only utilized to obtain the impulsive component corresponding to the faults from the REB, but also to reduce the dimension of vibration sources included in the sensor-picked signals. Consequently, the difficulty for applying the ICA algorithm under the conditions that the sensor number is limited and the source number is unknown can be successfully eliminated. Then, the ICA algorithm is employed to separate the envelopes according to the independence of vibration sources. Finally, the vibration features related to the REB faults can be separated from disturbances and clearly exposed by the envelope spectrum. Simulations and experimental tests are conducted to validate the proposed method.

Toward a Geocentric Framework of Trust: An Application to Organizational Trust

Integrating the typologies of trust dimensions and trust ideal-types with the new typologies of trust forms and trust bases, I propose a geocentric framework of trust in general and of organizational trust in particular. The typology of trust forms is built on the dimension of spatial strength to address the content of trust building from weak trust to strong trust and on the dimension of temporal stage to address the process of trust building from initial trust to mature trust. The typology of trust bases is built on the dimension of trust sources to address the bases of trust building from depersonalized sources to personalized sources and on the dimension of trust domains to address the bases of trust building from dyad domains to network domains. Together with its three pillars (trust-building mechanisms, leadership and trust-as-choice), the central theme of trust building connects all four trust typologies toward a geocentric framework that integrates and transcends the cultural values of the East and the West. This framework bears a special implication for theorizing about transaction cost and transaction value as a duality for interorganizational alliance.

Multi-scattering in active noise control

This paper follows up on an earlier paper of the author [1] dealing with the issue of multi-scattering in a typical active noise control system. This work concerns the effects of the presence of a neighboring wall on the performance of an active noise cancellation system when the dimension of sources is added to the analysis. Effect of the adjacent wall is taken into account using the image method, and multi-scattering is also allowed for by the spherical harmonic addition theorem. The recognized method of separation of variables and appropriate wave field expansions in spherical coordination are used to derive the required analytical solutions. A primary spherical source radiates at different modes, and a secondary source is modeled as a radially vibrating cap which resembles a real sound speaker. Our particular interest in this work is to investigate effects of multi-scattering at intermediate working frequencies of ANC, e.g., about 100–500 Hz. In addition to emphasizing the importance of multi-scattering, this work endeavors to find the appropriate cap angle of the control source to achieve acceptable noise attenuation for different vibrating modes of the primary source (monopole, dipole). Numerical results reveal that the presence of a rigid wall will considerably change the adequate velocity of the secondary source and also show that using a baffled spherical piston instead of a monopole control source will obviously improve the sound minimization efficiency when the primary source vibrates in the n = 1 mode in a low frequency range.

Qualitative case study in pedagogical research: Cognitive possibilities and limitations

This paper discusses the cognitive possibilities and limitations of case study, as a qualitative research approach, and the fields of its application in studying pedagogical problems. Special attention is paid to different ways of defining and usual criticism pointed at this strategy in methodological literature of recent date: (1) general, theoretical (context independent) knowledge is much more valuable from actual, practical (context dependent) knowledge; (2) one cannot perform generalizations based on an individual case and therefore case study cannot contribute to the development of science; (3) case study is the most useful in generating hypotheses, that is, for the first phase of research process, while other methods are more suitable for testing hypotheses and building a theory; (4) case study tends to be partial towards verification, that is, the tendency of a researcher to confirm his/her previously established concepts; (5) it is often very difficult to present in brief the specific case study, and especially difficult to deduce general suggestions and theories on the basis of a specific case study. The objections, therefore, regard the possibility of theory development, reliability and validity of the approach, or doubt in its scientific status. The author of this paper discusses the justifiability of these objections and points out to different methodological procedures of arranging and analyzing the data collected for studying the case, which contribute to the reliability of this research approach. As a general conclusion, it is stated that the case method contains all the features relevant for studying pedagogical phenomena: preservation of the integrality of the phenomenon, appreciation of its context, developmental dimension and complementariness of different data sources.

Fractional Brownian motion models for synthetic aperture radar imagery scene segmentation

The application of fractal random process models and their related scaling parameters as features in the analysis and segmentation of clutter in high-resolution, polarimetric synthetic aperture radar (SAR) imagery is demonstrated. Specifically, the fractal dimension of natural clutter sources, such as grass and trees, is computed and used as a texture feature for a Bayesian classifier. The SAR shadows are segmented in a separate manner using the original backscatter power as a discriminant. The proposed segmentation process yields a three-class segmentation map for the scenes considered in this study (with three clutter types: shadows, trees, and grass). The difficulty of computing texture metrics in high-speckle SAR imagery is addressed. In particular, a two-step preprocessing approach consisting of polarimetric minimum speckle filtering followed by noncoherent spatial averaging is used. The relevance of the resulting segmentation maps to constant-false-alarm-rate (CFAR) radar target detection techniques is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

THE SCALE OF NON-ADIABATIC HEATING AS A FACTOR IN CYCLOGENESIS

With the aid of a simple linearized model, the effect of large-scale atmospheric heat sources on a resting atmosphere has been investigated. Particular emphasis has been devoted to the study of the dependence of pressure change on the horizontal dimension of the heat sources. It is thus found that, when the maximum intensity in the center of the heat source is independent of the horizontal dimension, the pressure fall at the surface has a maximum when the width is about 4000 km in the case of no friction. With friction included, the pressure change also depends on the rate of heating. With decreasing rate of heating, the pressure fall at the surface thus decreases while the width for which the maximum occurs increases (4000 to 5000 km). The mean wind decreases monotonically with increasing width of the heat source except for the very smallest scales. In the case where the maximum intensity in the center of the heat source is proportional to the horizontal extent, the pressure fall at the surface increases monotonically with increasing dimensions. The dependence on the latitude and the stability is investigated.
