How different opinions in Black Lives Matter (BLM) regarding the notion of ally shed light on social movement and ally studies

ABSTRACT ‘Black Lives Matter’ (BLM) is a conflict about central societal norms, embodied by activities and social actors . Those actors share a common vision but differ on some points. Combining several kinds of data (digital ethnography, interviews, and observation), this article argues that one of those dissension points is the activists’ valorization of the notion of allyship, particularly white allyship. Critical Race Studies and Ally Studies assume that working towards allyship is inherently desirable. However, three ideal-typical positions exist within BLM regarding this statement: adhesion, partial adhesion, and rejection. Analysing those positions puts light on moral and strategic considerations that contribute to structuring BLM into several complementary trends.

Unsustainable practices among contemporary maritime fishing communities of Mallorca (Balearic Islands, Spain): A socioecological and historical approach

AbstractIn this research, we address the relationship that exists between the development of certain unsustainable fishing practices among professional small‐scale fishery, industrial fishery and recreational fishing and the historical and social changes observed in the configuration of maritime fishing communities in Mallorca (Balearic Islands, Spain). We also explore the impact that European, Spanish and regional policies have had on the strategies of exploitation of the marine environment and the forms of social organisation of these communities. To do this, we apply a multiproxy approach that includes several kinds of data: field research, photographic archives, oral interviews, local newspapers, legislation, official reports and published literature. The anthropological and historic viewpoints applied in the research delve into how the disappearance of traditional professional small‐scale fishing and the surge of both a bottom‐trawl fleet and recreational marine fishing have not only promoted a loss of sustainability and environmental balance in such coastal environments but have also led to a significant loss regarding key cultural and identity assets.

Data analysis for COVID-19 deaths using a novel statistical model: Simulation and fuzzy application.

This paper provides a novel model that is more relevant than the well-known conventional distributions, which stand for the two-parameter distribution of the lifetime modified Kies Topp-Leone (MKTL) model. Compared to the current distributions, the most recent one gives an unusually varied collection of probability functions. The density and hazard rate functions exhibit features, demonstrating that the model is flexible to several kinds of data. Multiple statistical characteristics have been obtained. To estimate the parameters of the MKTL model, we employed various estimation techniques, including maximum likelihood estimators (MLEs) and the Bayesian estimation approach. We compared the traditional reliability function model to the fuzzy reliability function model within the reliability analysis framework. A complete Monte Carlo simulation analysis is conducted to determine the precision of these estimators. The suggested model outperforms competing models in real-world applications and may be chosen as an enhanced model for building a statistical model for the COVID-19 data and other data sets with similar features.

A Discrete Exponential Generalized-G Family of Distributions: Properties with Bayesian and Non-Bayesian Estimators to Model Medical, Engineering and Agriculture Data

This paper introduces a new flexible probability tool for modeling extreme and zero-inflated count data under different shapes of hazard rates. Many relevant mathematical and statistical properties are derived and analyzed. The new tool can be used to discuss several kinds of data, such as “asymmetric and left skewed”, “asymmetric and right skewed”, “symmetric”, “symmetric and bimodal”, “uniformed”, and “right skewed with a heavy tail”, among other useful shapes. The failure rate of the new class can vary and can take the forms of “increasing-constant”, “constant”, “monotonically dropping”, “bathtub”, “monotonically increasing”, or “J-shaped”. Eight classical estimation techniques—including Cramér–von Mises, ordinary least squares, L-moments, maximum likelihood, Kolmogorov, bootstrapping, and weighted least squares—are considered, described, and applied. Additionally, Bayesian estimation under the squared error loss function is also derived and discussed. Comprehensive comparison between approaches is performed for both simulated and real-life data. Finally, four real datasets are analyzed to prove the flexibility, applicability, and notability of the new class.

Material evidence is also considered. It attempts to answer questions of who could act as an astrologer and what knowledge was required to become one. In addition, the paper discusses the position of astrologers in the temple hierarchy and other areas of knowledge in which astrologers were involved.

Digitaalinen diskurssi työelämän kontekstissa – menetelmällisiä haasteita ja ratkaisuehdotuksia

Digital technologies have become an inseparable part of most workplace activities. In this article, we discuss the study of digital work in the context of complex organizational practices. We lay out some methodological challenges and suggest some possible solutions to them. Firstly, we contend that we should take into consideration the multimedial nature of organizational practices. Secondly, several kinds of data – such as video-recordings of face-to-face encounters, screenshots from digital platforms, ethnographic observation and interviews – may be needed to gain an understanding of such practices. Thirdly, the analyst needs to pay attention to the affordances of the media that the participants display an orientation to through their action. In our conclusions, we discuss the consequences of our approach for publishing and application of research results.

TOWARDS AN ADVANCED CONSERVATION STRATEGY: A STRUCTURED DATABASE FOR SHARING 3D DOCUMENTATION BETWEEN EXPERT USERS

Abstract. Nowadays, the researchers in Cultural Heritage fields investigate more and more about advanced conservation strategies that comprehend the possibility to share and use 3D models and structured information related to them. One of the modern method adopted to achieve this goal is to use structured web-platform. These are online systems that can handle data, created to contain and support precise information. They simultaneously respond to the need for a common ground for different expert users and of a unique tool where to store several kinds of data, coming from heterogeneous sources. The article aims to show how it is possible to build a valid tool for the conservation and monitoring activities of CH, following the national and international legislation and the specific needs of the application field. In particular, it will deepen the criteria to build a 3D model that has to link a database of information, specifying the logic behind it. In the same way, it will show how to structure a database collaborating with the local institutions and experts, following the real needs of the site. The benefit is that this kind of tools gives to the multi-disciplinary works and projects a shared environment for storing and view a different type of data. They can help both the access intended to the conservation activities and both they can open to the public. The application field is the Sacri Monti circuit, which is part of the UNESCO World Heritage List since 2003.

Analysis of effective pore pressure in asphalt pavement based on computational fluid dynamics calculation

A micromechanical model was established based on the fluid dynamics theory. This model could be used to calculate several kinds of data when the asphalt pavement under the influence of traffic loading is in water-saturated condition. The results showed that the maximum pressure inside the effective pore was located at the junction between exit slits and the pore wall. There was a positive correlation between the pressure and the vehicle speed. Therefore, the repeated traffic loading could cause emulsification, shift and even peeling of the asphalt membrane. Moreover, the bigger size of the exit slit is, the higher velocity of the fluid has. The high velocity flow keeps scouring both the exit slit and the lower boundary of pore wall. It will cause a bigger slit. Pressure distribution inside the effective pore is related to the number of the exit slit which connect with the pore. More exit slits means bigger pressure inside the effective pore. In addition, if asphalt membranes at exit slits have micro-cracking, the cumulative damage could appear easily and asphalt membranes could be peeled easily. Finally, a test was conducted so as to obtain the bonding strength and adhesion strength between asphalt and aggregate. Then, we can get accurate damage form and position during the scour process by comparing the numerical simulation results with experiment results.

Research on Universal Processing Framework of Multi-source Heterogeneous Data Integration in GIS Domain Based on Software Technology

It is difficult to make fine-grained random call in GIS system development or data processing owing to the multi-source heterogeneity of spatial data. Moreover, to convert the data into a unified format easily can lead to the loss of the core attributes. In this paper, we discuss the translation methods among several different data formats, including attribute and business data , network data, CAD data, heterogeneous GIS spatial data, and domestic and foreign GIS data, etc, based on software technology like FME, MyFME, Arcgis, MessagePack package, crawling tools and so on. Then, we propose a universal processing framework for multi-source heterogeneous data integration in the GIS field, and verify the performance of the proposed framework through integrating several kinds of data.

A well-started beginning elementary teacher’s beliefs and practices in relation to reform recommendations about inquiry-based science

Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher’s (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia’s beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia’s beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia’s beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.

Participatory photography: language minority teenagers’ sense of belonging?

This article discusses the different ways of using photography as a research method in social sciences, especially how using participatory photography with young people and children is explored. The advantages of making teenagers and children co-researchers as well as some of the issues that emerge, like lack of control over the data collection and ethical issues, are examined. A case study on language minority teenagers’ identifications with and sense of belonging to the language minority group is offered as an example of participatory photography. The interplay between the photographs and the texts produced by the teenagers exemplify the necessity of using several kinds of data instead of only photographs.

환경 측정을 위한 모바일 다기능 센서의 구현

The environment information such as dust, temperature, humidity, illumination and gas are very important in daily life. We implemented multi-sensor system which made for measuring an environment by using Arduino, ZigBee, and Appinventor. We also designed a packet for transmitting environment data. The data are sent to the server via ZigBee and then it communicates to a smart phone via WI-Fi. In this study, we added divers sensors, designed a protocol which made for transfer several kinds of data and improve mobility for real time monitoring by using smart phones. The system was worked well and the data was transmitted correctly to the smart phone.

Correlation Analysis on Interferometric Coherence Degree and Probability of Residue Occurrence in Interferogram

The interferometric coherence degree is a very important indicator of the quality of interferometric phase values in interferogram; while the existence of residues is a stubborn problem for phase unwrapping. Both of them are the vital factors influencing the performance of phase unwrapping algorithms in interferometric synthetic aperture radar (SAR) processing. In general, residues tend to be located in the regions with low coherence degree, which is just a qualitative description for the relationship between interferometric coherence degree and probability of residue occurrence. In order to further reveal the quantitative relationship between them, we actually used the residue density in the interferogram as an approximate substitute for the probability of residue occurrence, and then calculated the Pearson correlation coefficients between the ensemble coherence average and the residue density in the corresponding interferogram with several kinds of data from different SAR sensors, including ERS1/2, JERS-1, and Envisat-1 ASAR. The calculation results show a very strong inverse correlation between them, the Pearson correlation coefficients range from -0.702 to -0.963. In other words, the interferometric coherence degree not only can indicate the quality of interferometric phase, but also to a great extent reflect or even predict the density of residues in the interferogram using the linear regression analysis.

NMEA-0183을 이용한 효율적인 멀티미디어 데이터 전송

BNWAS의 기능과 동작은 국제 표준을 통해 제안되었으나, 현재 배에 탑재되어 있는 BNWAS는 모니터링하는 것에 많은 어려움을 가지고 있다. NMEA-0183, NMEA-2000과 같은 BNWAS내의 장비에서 생성되는 여러 데이터가 있다. 본 논문에서는 주로 BNWAS에서 사용되어지고 있는 저속 NMEA-0183을 기반으로 한 통신 프로토콜을 이용한 멀티미디어 전송 기법을 제안하였다. NMEA-0183을 통한 저속 멀티미디어 데이터 서비스의 원만한 전송을 위해서는 데이터 압축 기술이 필요하다. 현재 주로 사용되어지고 있는 NMEA-0183 프로토콜이 배의 장비에 주로 사용되어지나, 센서를 통한 BNWAS 장비를 제어하기 위해서는 보다 효율적인 NMEA-0183 프로토콜 전송이 필요할 것이다. The functionality of BNWAS and its operations are investigated through its international standard. But the BNWAS is being used currently in the ship had difficulty in monitoring. Several kinds of data are generated from many equipments in BNWAS, such as NMEA-0183 data or NMEA-2000. In this paper, we have proposed a method of the multimedia data transmission using a communication protocol based on slower NMEA-0183, which is mainly used in BNWAS. Data compression techniques are needed for smooth streaming services of the multimedia data in the low data rate over the NMEA-0183 interface. Although these data are mainly used for the instruments of ship, their efficient transmission may be needed if they are managed to control the BNWAS equipment with sensors.

Tracing a Beginning Elementary Teacher’s Development of Identity for Science Teaching

The purpose of this case study was to examine a beginning elementary teacher’s development of identity for science teaching from her first year at university, her field experience, and through her first year of teaching. Several kinds of data were collected over a period of 5 years through different sources: interviews, journal entries, drawing assignments, biographical assignments, lesson plans, and classroom observations. Grounded within a combined theoretical framework of identity and narrative, these data were analyzed by means of open coding techniques. The findings of the data analysis are presented under the following four main themes—(a) discourse identity: embracing and enacting scientific inquiry; (b) affinity identity: the impact of relationships and science learning experiences; (c) nature identity: women in science; and (d) institution identity: the role of the context. The findings are summarized in three main assertions, which are discussed alongside a set of implications for research and teacher preparation.

How are newspaper companies using social media to engage and connect with their audiences? characteristics and forms of Korean newspapers’ YouTube use

The present study classifies the characteristics of YouTube use by South Korean newspapers in terms of both “local proximity” and “reported them” of news content. Several kinds of data related to news production and consumption were collected from the opening of the YouTube account to October 11, 2012. Findings suggest that news content strategies for YouTube are different across newspapers. National newspapers are likely to perceive YouTube as a new medium, whereas local newspapers tend to perceive it as an extension of the existing newspaper. The results also reveal that YouTube strategies based on strongly partisan or critical reports or oppositional parodies can work better than those providing a diverse and universally appealing range of content.

Ecotoxicity of artificial sweeteners and stevioside

Produced, consumed and globally released into the environment in considerable quantities, artificial sweeteners have been identified as emerging pollutants. Studies of environmental concentrations have confirmed the widespread distribution of acesulfame (ACE), cyclamate (CYC), saccharin (SAC) and sucralose (SUC) in the water cycle at levels that are among the highest known for anthropogenic trace pollutants. Their ecotoxicity, however, has yet to be investigated at a larger scale. The present study aimed to fill this knowledge gap by systematically assessing the influence of ACE, CYC and SAC and complementing the data on SUC. Therefore we examined their toxicity towards an activated sewage sludge community (30min) and applying tests with green algae Scenedesmus vacuolatus (24h), water fleas Daphnia magna (48h) and duckweed Lemna minor (7d). We also examined the effects caused by the natural sweetener stevioside. The high No Observed Effect Concentrations (NOECs) yielded by this initial evaluation indicated a low hazard and risk potential towards these aquatic organisms. For a complete risk assessment, however, several kinds of data are still lacking. In this context, obligatory ecotoxicity testing and stricter environmental regulations regarding food additives appear to be necessary.
