Magnetic mineralogy of Variscan granites from northern Portugal: an approach to their petrogenesis and metallogenic potential
Authors: Cruz C. , Sant'Ovaia H. , Noronha F.
Published: March 2020

Northern Portugal is characterized by the occurrence of numerous W hydrothermal deposits spatially associated with granites. The primary goal of this work is to establish a relationship between the magnetic behavior of thegranites and the redox conditions during magma genesis, as this can influence the occurrence of mineralizations, namely of W (Mo). To this end, the magnetic mineralogy of the granites of the Lamas de Olo Pluton, a posttectonic pluton in northern Portugal, with associated W (Mo) occurrences was characterized and compared with the magnetic mineralogy of other post-tectonic Variscan plutons. This pluton is composed of different biotite granites: Lamas de Olo, Alto dos Cabeços and Barragem. To better characterize its magnetic behavior, differentanalytical techniques that complement previous magnetic susceptibility studies were performed. The magnetic mineralogy of Lamas de Olo Pluton was then compared with other post-tectonic Variscan plutons such as the Vila Pouca de Aguiar, Peneda-Gerês and Lavadores-Madalena plutons. The presence of magnetite in some of these granites is important because it points to melt-oxidized conditions not commonly found in Iberian Variscan granites. Our study shows that granite areas where magnetite and/or magnetite/ilmenite coexist are important targets for W (Mo) mineralizations. The results indicate that a few plutons have granites with a complex redox history which leads to the formation of magnetite and ilmenite.

Published: March 2020

Fasteners are critical and indispensable locking components in mechanical assembly. Submillimeter fasteners are massively and widely used in electronic devices. This study proposed an adjustable panoramic inspection system for M2 to M0.8 submillimeter fasteners. The system mainly consists of a panoramic imaging module, a back-light module, and an image grabbing and computing module. The panoramic imaging module would form four equal optical path lengths to keep the same imaging amplification between the different directions of the field of view. The back-light module was designed to provide uniform illumination and enhance the contrast of the pitch edge between the fasteners and the background. The image grabbing and computing module with a high-speed camera was designed to be adjustable for different sizes of submillimeter fasteners. The realized system can offer the function of four images in one shot to make a panoramic scene, independent illumination for recognizing, inspect screws from M0.8 to M2.0 screws, and short time consumption of image processing, such as 3.284 ms for M0.8 screws and 2.384 ms for M2.0 screws, to achieve examination of 6000 pieces in 1 min.

Published: March 2020

This study proposed label-free fluorescence lifetime imaging and phasor analysis methods to discriminate different grades of cervical intraepithelial neoplasia (CIN). The human cervical tissue lesions associated with cellular metabolic abnormalities were detected by the status changes of important coenzymes in cells and tissues, reduced nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) and flavin adenine dinucleotide (FAD). Fluorescence lifetime imaging microscopy (FLIM) was used to study human cervical tissues, human cervical epithelial cells, and standard samples. Phasor analysis was applied to reveal the interrelation between the metabolic changes and cancer development, which can distinguish among different stages of cervical lesions from low risk to high risk. This approach also possessed high sensitivity, especially for healthy sites of CIN3 tissues, and indicated the dominance of the glycolytic pathway over oxidative phosphorylation in high-grade cervical lesions. This highly adaptive, sensitive, and rapid diagnostic tool exhibits a great potential for cervical precancer diagnosis.

We describe the design, construction, calibration, and characterization of a multi-primary high dynamic range (MPHDR) display system for use in vision research. The MPHDR display is the first system to our knowledge to allow for spatially controllable, high dynamic range stimulus generation using multiple primaries. We demonstrate the high luminance, high dynamic range, and wide color gamut output of the MPHDR display. During characterization, the MPHDR display achieved a maximum luminance of

Authors: Zhu Chang-qing , Wang Jin-guang , Li Yi-fei , Feng Jie , Li Da-zhang , He Yu-hang , Tan Jun-hao , Ma Jing-long , Lu Xin , Li Yu-tong , Chen Li-ming
Published: March 2020

Using a Dazzler system and tilting a compressor grating, we provide an effective way of using the laser group delay dispersion to continuously steer the electron beam accelerated by an asymmetric laser wakefield. The deviation angle of the electron beam was the same as that of the angularly chirped laser pulse from its initial optical axis, which is determined by the laser pulse-front-tilt (PFT). This method can be utilized to continuously control over the pointing direction of electron bunches to the requisite trajectories, especially for practical applications in highly sensitive alignment devices such as electron-positron colliders or undulators. Additionally, we investigate the effect of PFT on the properties of the electron beam.

Published: March 2020

We present the use of a computer-generated hologram (CGH) to test the mid-spatial frequency error of a large aperture long-focal-length lens. In order to verify this test approach, a 450 mm × 450 mm reflective CGH is designed and fabricated for testing the 440 mm × 440 mm spatial filter lens. Both 0th and 1st order diffraction wavefront of CGH are measured, and the 0th order diffraction wavefront is used to calibrate the substrate error. The mid-spatial frequency wavefront error caused by the CGH fabrication errors are evaluated using the binary linear grating model and power spectral density (PSD) theory. Experimental results and error analysis show that the CGH test approach is also feasible for the measurement of mid-spatial frequency error, and the measurement accuracy of PSD1 can reach 0.8832 nm RMS.
Retrieving the optical transmission matrix of a multimode fiber using the extended Kalman filter
Authors: Huang Guoqiang , Wu Daixuan , Luo Jiawei , Huang Yin , Shen Yuecheng
Published: March 2020

Characterizing the transmission matrix (TM) of a multimode fiber (MMF) benefits many fiber-based applications and allows in-depth studies on the physical properties. For example, by modulating the incident field, the knowledge of the TM allows one to synthesize any optical field at the distill end of the MMF. However, the extraction of optical fields usually requires holographic measurements with interferometry, which complicates the system design and introduces additional noise. In this work, we developed an efficient method to retrieve the TM of the MMF in a referenceless optical system. With pure intensity measurements, this method uses the extended Kalman filter (EKF) to recursively search for the optimum solution. To facilitate the computational process, a modified speckle-correlation scatter matrix (MSSM) is constructed as a low-fidelity initial estimation. This method, termed EKF-MSSM, only requires 4N intensity measurements to precisely solve for N unknown complex variables in the TM. Experimentally, we successfully retrieved the TM of the MMF with high precision, which allows optical focusing with the enhancement (>70%) close to the theoretical value. We anticipate that this method will serve as a useful tool for studying physical properties of the MMFs and potentially open new possibilities in a variety of applications in fiber optics.

Buscar melhoria para uma sociedade desorganizada e despreparada é preciso que a educação e as políticas públicas estejam interligadas e em plena harmonia para que se tenham bons resultados. Falar em reabilitação de uma juventude quase que praticamente perdida, chega a ser uma utopia. Dentro deste contexto, o intuito deste artigo é buscar parcerias com as políticas públicas e os profissionais da educação para que haja a oportunidade de mudança e eficácia nessa busca de reabilitação. Junto com uma equipe multifuncional, recuperar não somente os internos, mas também, a família que junto com ele, encontra-se doente e necessita de ajuda. A sociedade moderna é uma corporação de disposições que fundamentalmente se encontram as oportunidades de realização profissional e de sobrevivência, aplicando-se o que se sabe e ainda acrescenta outros saberes, assim como trocando trabalho por dinheiro. Para que haja uma recuperação verdadeiramente efetiva, vale ressaltar a aplicação de terapia em grupo roda de conversa, cursos profissionalizantes, assistência psicológica e conhecimento com relação ao estado que se encontram. No entanto, a reabilitação psicossocial e a reinserção social são analisadas, pelos documentos normativos que satisfazem as políticas públicas sobre drogas, como linhas centrais no cuidado aos indivíduos com dificuldades relacionadas ao uso de substâncias psicoativas.  Como metodologia será aplicada o método de cunho qualitativo, pesquisas bibliográficas e pesquisa-ação. E por fim, a busca de parcerias com as políticas públicas e empresas para que haja uma ressocialização do indivíduo, e assim, o mesmo sinta-se um cidadão recuperado com uma profissão que o volte a dignidade social. Palavras – chave: Reabilitação, Equipe Multifuncional, Família, Dignidade Social.

Authors: Torres Andrea , Kappes Maria soledad , Riquelme Verónica , Neumann Nicole , Vargas Liliana , Espinoza Melissa
Published: March 2020

Introducción: La obesidad infantil representa un problema de salud pública a nivel mundial. Chile presenta una de las tasas más altas de prevalencia de obesidad infantil de Latinoamérica. Localmente, hay pocos estudios que muestran las diferencias entre colegios públicos y privados en relación a parámetros de peso, talla y perímetro de cintura en escolares. El objetivo de este estudio es determinar si existen diferencias antropométricas de niños de 5 y 6 años según el tipo de colegio.Material y métodos: Se realizó una investigación cuantitativa, descriptiva y transversal. Se constituyó una muestra no probabilística de 195 niños de 5 y 6 años, los cuales 55 corresponden a colegio público y 140 a colegio privado. Resultados: En la valoración antropométrica de niños entre 5 y 6 años de colegios públicos y privados, los escolares en peso y talla en ambas edades no fueron estadísticamente significativas (p>0,05), sin embargo, la población en conjunto, sin diferenciar en edades, fueron estadísticamente significativas en la talla (p<0,05). Los valores de IMC para 5 y 6 años se encuentran bajo los puntos de corte de obesidad definidos internacionalmente y fueron estadísticamente significativas entre colegio público y privado (p<0,05). En perímetro de cintura, los escolares de colegios públicos tuvieron más escolares sobre el Percentil 90, catalogado como obesidad abdominal. Sin embargo, estas diferencias encontradas no fueron estadísticamente significativas (p>0,05). Conclusiones: Se evidenció menor talla (p<0,05), mayor peso y mayor perímetro de cintura en escolares de colegio público en relación a privado, sin embrago dado la baja participación de colegios y diferencia de tamaño muestreal en ambos grupos, estas diferencias deben ser interpretadas con cautela.

Cross Recruitment of Domain-Selective Cortical Representations Enables Flexible Semantic Knowledge
Authors: Fairhall Scott L.
Published: March 2020

Knowledge about objects encompasses not only their prototypical features but also complex, atypical, semantic knowledge (e.g., “Pizza was invented in Naples”). This fMRI study of male and female human participants combines univariate and multivariate analyses to consider the cortical representation of this more complex semantic knowledge. Using the categories of food, people, and places, this study investigates whether access to spatially related geographic semantic knowledge (1) involves the same domain-selective neural representations involved in access to prototypical taste knowledge about food; and (2) elicits activation of neural representations classically linked to places when this geographic knowledge is accessed about food and people. In three experiments using word stimuli, domain-relevant and atypical conceptual access for the categories food, people, and places were assessed. Results uncover two principles of semantic representation: food-selective representations in the left insula continue to be recruited when prototypical taste knowledge is task-irrelevant and under conditions of high cognitive demand; access to geographic knowledge for food and people categories involves the additional recruitment of classically place-selective parahippocampal gyrus, retrosplenial complex, and transverse occipital sulcus. These findings underscore the importance of object category in the representation of a broad range of knowledge, while showing how the cross recruitment of specialized representations may endow the considerable flexibility of our complex semantic knowledge.

SIGNIFICANCE STATEMENTWe know not only stereotypical things about objects (an apple is round, graspable, edible) but can also flexibly combine typical and atypical features to form complex concepts (the metaphorical role an apple plays in Judeo-Christian belief). In this fMRI study, we observe that, when atypical geographic knowledge is accessed about food dishes, domain-selective sensorimotor-related cortical representations continue to be recruited, but that regions classically associated with place perception are additionally engaged. This interplay between categorically driven representations, linked to the object being accessed, and the flexible recruitment of semantic stores linked to the content being accessed, provides a potential mechanism for the broad representational repertoire of our semantic system.

Published: March 2020

Umrah carried out by agencies of a travel agency with several provisions issued by the ministry of religion RI. The meaning of mahram that was set by the ministry of religion is include to a mahram pilgrims, mahram referred in family relationship or marriage. This is regulated by the rules of registration of pilgrims and associated with the administration of Hajj and Umrah service. So that they try as much as possible to include a mahram as defined in the shari'ah by including the documents to indicate the mahram validation. They try to make it all based on the documents which corroborate these requirement as evidence of the validity of requirement. The provision as above, would be very detrimental to women those will carry out the pilgrimage, because they will be burdened with additional costs while they did not get the expected benefits. For contextual understanding that participation of mahram can be interpreted as safety. But in pilgrimage, mahram has not been found detailed provisions in the pilgrims discurs. By paying a "mahram money" for women under 40 years old those without mahram in $ 300,000 upto $. 600,000, they will be looked for a Mahram by officer. Although, for the fact or in practice, during Umrah trip, they are not accompanied by a mahram that should accompany during the implementation of Umrah.
Ritualitas Ibadah, Antara Qurbah dan Kurbah Dari Dimensi Spiritual-Dogmatis Sampai Dimensi Sosial-Praktis
Authors: Syukur Abdul
Published: March 2020

Pemahaman antara berqurban (dengan huruf ‘q’) dan berkurban (dengan huruf ‘k’), bagi kebanyakan lidah masyarakat Indonesia, sering diartikan simpang siur, sehingga tidak jarang makna hakiki dari ibadah itu sendiri lebur begitu saja dengan sangat mudah. Padahal, jika direnungkan lebih mendalam, masing-masing term memiliki karakteristik yang khas. Di dalamnya, meskipun terkadang memiliki tujuan yang sama, yakni sesuatu yang bisa saja berbentuk materi untuk orang lain yang membutuhkan atau kesusahan, baik sebagai korban kezhaliman atau korban bencana alam, namun akan nampak jelas perbedaan pada penghayatan keduanya. Tulisan ini mencoba untuk menjembatani, dan sebisa mungkin akan memberikan penyelesaian terhadap seputar pembahasan kedua terminologi tersebut.
FENOMENA LGBT DALAM PERSPEKTIF HAM DAN DOKTRIN AGAMA (SOLUSI DAN PENCEGAHAN)
Authors: Ghozali Abdul Malik
Published: March 2020

Lesbian, Gay, Bisexual and Transgender movements are now a mondial phenomenon. The LGBT community has dared to show itself to the surface. Not only in the Western world alone, but LGBT excitement also rife in the homeland. The emergence of LGBT community in the midst of people's life raises pro and contra. Some people criticize the existence of the LGBT community, because it is considered a people with abnormal behavior and deviates from religious teachings. Others accept it as part of appreciating their exclusion in Human Rights. This study attempts to answer some key questions: What are the views of Islamic teachings and the Human Rights Charter on LGBT behavior? How can the human rights and religious doctrine match in solving this LGBT problem? What are the LGBT prevention solutions and solutions that can be done? To answer this question, research is done by studying religious texts be it the Qur'an or hadith, and the text of the Human Rights Charter. Both types of texts are examined in various approaches; theological, historical, philosophical, medical, tafsir, hermeneutical, jurisprudence and psychological. Content analisys method was initially performed on the text of the Qur'an and the hadith. Matan hadith explored by takhrij method and study of hadith text. From this study, it is concluded that LGBT behavior in religious doctrine is strictly prohibited. Likewise the Human Rights Charter can not justify LGBT behavior under the pretext of individual freedom. Because individual freedom is automatically limited by other individual freedoms and legislation. Treatment and prevention solutions can be done to LGBT behaviors. Because psychically, LGBT behavior is a psychiatric disease that can be treated and prevented.
Model Pemahaman Front Pembela Islam (FPI) Terhadap Al-Qur’an Dan Hadis
Authors: Wahid Abdul Hakim
Published: March 2020

The Islamic Defenders Front (FPI) is very famous for the amar ma'ruf and nahi mungkar movement, and launched the national anti-immoral movement. However their movement always seems to use violence, so there is a presumption that FPI's religious pattern shows the influence of petro Islam that rigidly and textually-dominated with a harsh understanding to the practice of violation on religious values. With the semantic approach to the Habib Riziq’s book entitled Dialog FPI-Amar Ma'ruf Nahi Munkar, this paper prove that the FPI's interpretation to the Qur'an and hadiths which is the reference of their every action, has used a contextual approach, but seems that their understanding is less comprehensive.
Kehujjahan Ḥadīth Mawqūf Menurut Muḥaddithīn: Studi Analisis Terhadap Kedudukan Ḥadīth Mawqūf Sebagai Sumber Hukum Islam
Authors: Lisalam Reva Hudan
Published: March 2020

This article wants to prove that not all the opinions of friends contained in the ḥadīth mawqūf are a compulsory hujjah that must be followed by Muslims afterwards. This is related to the call that arose from some Islamic groups to restore and limit the meaning of the Qur’an and the Prophet’s only in the understanding of generations of friends so that they do not justify the existence of ijtihād on the friend’s ijtihād. This type of research used in this article is library research, namely by inventorying some thoughts about the Hadith Mawquf from the ulama, especially muḥaddithīn because the study of the mawqūf ḥadīth is more deeply discussed in the ḥadīth discipline.

Published: March 2020

This article explores the insights of inclusivism and tolerance in Islamic religious education (PAI) textbooks in Brawijaya University (UB) Malang. This article is the result of research by reading textbooks, interviewing six PAI lecturers and focus group discussions (FGD) at UB Malang in December 2018. In general, there are many material aspects in the textbooks that encourage students to be open, respect for diversity and behave tolerant of different Islamic schools of thought. This is emphasized by the PAI lecturers since UB is a public university belong to the public and because in Islam itself there are many different understandings and schools of thought. The spirit of inclusivism, cosmopolitan and tolerance is seen explicitly in PAI UB’s textbooks and becomes the vision of PAI lecturers. If there is a deviation from the book tends to be a closed ideology, intolerant, and against the Republic of Indonesia, then it can be ascertained because of the “lecturer initiative” personally, and do not represent Lembaga Pusat Pembinaan Agama (the Central Institution of Religious Development).

ABSTRACT Background: Huntington’s disease (HD), caused by an expanded CAG repeat at HTT, has no treatment, and biomarkers are needed for future clinical trials. Objective: The objective of this study was to verify if free carnitine and branched chain amino acids levels behave as potential biomarkers in HD. Methods: Symptomatic and asymptomatic HD carriers and controls were recruited. Age, sex, body mass index (BMI), age of onset, disease duration, UHDRS scores, and expanded CAG tract were obtained; valine, leucine, isoleucine, and free carnitine were measured. Baseline and longitudinal analysis were performed. Results: Seventy-four symptomatic carriers, 20 asymptomatic carriers, and 22 non-carriers were included. At baseline, valine levels were reduced in symptomatic and asymptomatic HD carriers when compared to non-carriers. No difference in free carnitine or isoleucine+leucine levels were observed between groups. BMI of symptomatic individuals was lower than those of non-carriers. Valine levels correlated with BMI. Follow-up evaluation was performed in 43 symptomatic individuals. UHDRS total motor score increased 4.8 points/year on average. No significant reductions in BMI or valine were observed, whereas free carnitine and isoleucine+leucine levels increased. Conclusions: Although valine levels were lower in HD carriers and were related to BMI losses observed in pre-symptomatic individuals, none of these metabolites seem to be biomarkers for HD.

Abstract A larger therapeutic window for stroke treatment requires a significant change in the organization of emergency services, avoiding the increase in number of imaging exams and indirectly the time to treatment. Objective: To highlight the relation between faster clinical evaluation and stroke over-suspicion and consequently excessive imaging acquisition. To identify predictors of ischemic stroke and stroke mimics (SM), aiming for better patient selection for comprehensive neuroimaging and reperfusion therapies. Methods: Retrospective, cohort, observational, single-center study that reviewed all consecutive files of patients presenting with acute neurological symptoms who underwent CT scan or MRI from July 1, 2016 to July 1, 2017. Results: 736 patient files were reviewed. 385 patients (52.3%) presented with confirmed acute ischemic infarct, 93 (12.6%) had another brain lesion mimicking acute ischemia, and 258 (35.1%) had normal imaging. Acute stroke was more frequent in elderly patients with atrial fibrillation, arterial hypertension, or dysarthria or right motor impairment. Stroke mimic was associated with female patients with low vascular risk factors, low NIHSS, and patients with decreased level of consciousness or symptoms suggestive of posterior circulation. Discussion: 47.7% of all patients seen at the stroke unit did not have acute stroke lesions. Clinical assessment data have been used to provide indicators of acute stroke and stroke mimic patients, and symptoms corresponding to acute stroke and stroke mimic seem to be similar in the literature. Conclusion: Considering that the number of patients admitted for stroke treatment will increase even further with a larger therapeutic window for mechanical thrombectomy and for thrombolysis, a diagnostic decision-making algorithm for stroke patients is required in order to reinforce the suspicion of stroke indicating an urgent MRI.

Hollowcore slab with alternative cementitious materials for winter conditions
Authors: Korde Chaaruchandra , Cruickshank Matthew , West Roger P.
Published: March 2020

The precast industry, due to its specific early-age strength requirements for hollowcore (HC) slab products, has been reluctant to introduce alternative cementitious materials such as ground granulated blast-furnace slag (GGBS) due to the slower strength development of such materials. This paper reports on a study undertaken at a precast production facility to examine how to overcome the consequences of strength loss due to the replacement of up to 50% of CEM I (42·5R), as usually used in cold weather conditions, with GGBS, for environmental or durability reasons. The GGBS concrete slabs were activated using thermal, chemical and mechanical means to enhance their early-age strength gain. The results were compared at early ages in terms of the temperature profile during curing, cube compressive strengths, load-carrying capacities for transportability requirements, ultimate load and short-term creep. In addition, 28 d densities and strengths were compared for in situ cubes and cores extracted from HC slab samples. The experimental results showed a favourable potential for replacing CEM I (42·5R) cement with up to 50% GGBS in winter without compromising on factory productivity.

Steel reinforcement corrosion due to chloride penetration into concrete is one of the main causes of the degradation of marine structures and has been the subject of much research. Among the various factors that influence chloride penetration into concrete are environmental factors such as temperature and exposure conditions. In this context, the present study evaluated chloride penetration for three different exposure conditions (atmospheric, tidal variation and submerged) at temperatures of 15°C, 20°C, 25°C and 30°C over 18 months; samples were collected every 6 months, at depths of 1–5 mm. The environmental conditions were simulated in the laboratory. The results showed a higher concentration of chlorides in the submerged specimens. Moreover, the chloride concentration increased more intensively from 6 to 12 months and temperature was more influential above 20°C. The temperature effects were also found to be higher at advanced ages.
An instrumented large soil column to investigate climatic ground interaction

The field monitoring of the climatic-induced behaviour of the expansive soil has always been difficult, expensive and time consuming. The uncontrollability of the field boundary conditions and the difficulty in accurately measuring them have worsened the problem. As an alternative, the instrumented model set-ups are ideal for long-term monitoring of expansive soils since the laboratory compacted expansive soils become environmentally stabilised after few wet–dry cycles. There had been a very limited laboratory-based column set-ups for the observation of expansive soils under unsaturated conditions with an appropriate set of sensors embedded at known depths. The major difficulties associated with model tests are considerable boundary effect and sensor-to-soil area ratio due to the insufficient physical model dimensions. In this study, the research need for a laboratory model set-up with minimised boundary effects has been addressed by a large instrumented soil column, which could more closely represent environmentally stabilised soil. The current results depict the expected pattern for the variations of soil suction, volumetric water content and soil displacement under wetting and drying phenomenon, which accentuates the applicability of instrumented soil column for the investigation of climatic-induced expansive soil behaviour.

Published: March 2020

Tourism as a sphere of economic activity is growing quickly nowadays. Baikal natural territory, unique in its richness and variety, is one of the key competitive advantages of our country as a tourism destination. Lake Baikal is on the top of the most popular Russian natural sites rating on UNESCO World Heritage list. The number of tourists visiting Baikal is growing steadily. Thus, in 2016, both the Irkutsk region and the Buryat Republic were visited by more than 2,5 mln. officially registered tourists including more than 500.000 foreign ones. The following significant problems caused by increase in tourist flow are considered in the article: illegal land seizure and unauthorized building of recreational centers; noncompliance of recreational centers with mandatory health requirements; lack of water production licenses, drain treatment, waste storage and utilization; coasts littering and lack of a valid waste management system; poaching; illegal logging and violation of nature reserve protection regime. Harmonization of sustainable tourism development also presupposes, besides the objectives already set many years ago, the following factors: temporarily restricted access to certain areas; regulation of the tourists flow and location of resorts; regulation of certain goods consumption within Baikal nature reserve area; changing international legislation which regulates visiting world heritage objects; encouraging use of green (sustainable and environmentally-friendly) technologies at the tourist infrastructure enterprises.

Published: March 2020

In the era of the competition of cities for their inhabitants and attracting investment for their development, an interesting, recognizable (strong) brand has a significant impact on its competitiveness. At the same time, the analysis of modern scientific literature indicates the absence of a unified approach to the definition of a brand; a particular difficulty is the insufficient definition of the concepts of a territory brand and a city brand. This article is devoted to the study of the development problems and the formation of the brand of Irkutsk. The aim of the work is the analysis of various sociological studies conducted in recent years, in which the opinion of the inhabitants of the city of Irkutsk on its image is studied. The results will serve as one of the elements in the development of the city’s brand. The authors analyze the sociological studies which used various research methods: a semi-structured interview, a questionnaire, a content analysis of electronic media. They observe the individual components of the city’s image and highlight their influence on the formation of the city’s brand. The authors identify the key city symbols and interpret their specific character according to the Irkutsk residents. They come to the conclusion that the inhabitants of Irkutsk consider it necessary to form the concept of the city, which should become the basis for creating a brand of the city and of the territory as a whole.

Published: March 2020

The article examines the problems of developing electronic document flow in terms of widespread use of computer processing of the accounting information. It shows the influence of management approaches on developing the document flow (system, functional, process, risk-situational); it offers to identify the counting (technological and information) function as an independent object of electronic document flow in its interrelation with the control and analytical function performed by accountants; it specifies the bottleneck in the electronic document flow system — the control of the input, development, storage of of electronic documents while maintaining the requirements for their completeness, accuracy and legal full value. When developing the legal framework for electronic document flow, the methodological approach should be changed so that in the process of rulemaking the essential basis of the concepts and terms introduced is not replaced by technical standards. The article considers the judicial practice of documenting the delivery of goods in electronic document flow. It notes a number of positive changes in the position of the judiciary on the merits of considering еру issues of electronic document flow.
