FROM VILLAGE COMMONS TO PUBLIC GOODS
Authors: Trémon Anne-Christine
Published: October 2023

Illuminating the complex processes of China’s uneven urbanization through the lens of the transition from village commons to public goods, this book is set in three urbanized villages in Shenzhen, Chengdu, and Xi’an, which have experienced similar demographic explosions and dramatic changes to their landscapes, the livelihoods of its inhabitants, and the power structures governing their residents. Graduated provision is the delivery of public goods informed by the teleological ideology of urbanization, and by neoliberalism with Chinese characteristics, and has been employed as an answer to the challenges of making public goods, such as welfare provisions, public parks, education, and senior care, equally accessible to all in recently urbanized communities.
PERFORMING MEMORY
Authors: Passerini Luisa , Reinisch Dieter
Published: October 2023

Through a post-1968 perspective on the past 50 years, Performing Memory brings together case studies on new developments in the relationship between politics and visual representation—including the histories of dance, theatre, political performance and cinema—and investigates how they relate to the interlinked concepts of visuality, corporeality and mobility. Using a collective transdisciplinary attitude from within historical disciplines, and looking across to artistic fields, this volume demonstrates that memory is not merely a recollection of experience but an interactive process, in which the body, mobile and constrained, is both a point of departure and reference.
CREATION AND CREATIVITY IN INDIGENOUS LOWLAND SOUTH AMERICA
Authors: Halbmayer Ernst , Goletz Anne
Published: October 2023

Investigating local Indigenous processes of creation and creativity, this book uses ethnographic and comparative anthropological perspectives to enquire about creative transformative practices in lowland South America. The volume shows how people create and reinforce their conditions of being by employing different genres of transgression and by creatively shifting contexts of significance. Local socio-cosmic orders, the interrelation of creative genres (myth, verbal art, song, ritual, and handicrafts), and their changing frames of reference (from communal celebrations to wider political and commercial realms) demonstrate the relational, generative, and processual quality of Amerindian creativity.
Reckoning with Law—and with Legal Anthropology
Authors: Goodale Mark
Published: October 2023

I recently experienced one of those unsettling, context-imposing moments that cause the ground underfoot to feel suddenly loose, threatening to dissolve into quicksand – until, that is, the moment passes, as it inevitably seems to do. It happened during a university-wide lecture by Mark Williams, a professor of palaeontology at the University of Leicester and the Palaeontological Association's ‘exceptional lecturer’ for the academic year 2022–2023. This means he was chosen to go on a global tour of universities to give a talk for wider audiences that was intended to show the relevance and importance of palaeontology for questions of global significance. The title of Williams's lecture was ‘The Anthropocene: Planetary Scale Change to the Biosphere and the Future Well-Being of Planet Earth’.
Metropolitan Transportation Commission Discretionary Transit Funding Methods Evaluation
Authors:   Mineta Transportation Institute, Ferrell Christopher E. , Eells John M. , Reinke David , Lee Richard
Published: October 2023

In 2021, the Santa Clara Valley Transportation Authority (VTA) approached the Mineta Transportation Institute (MTI) with a proposal to have MTI provide an evaluation of the Metropolitan Transportation Commission’s (MTC’s) operational discretionary funding allocation policies and methods for Bay Area transit operators. The research was done in two parts. Part 1 investigated MTC’s past and current allocation methods for discretionary operational transit funding programs; Part 2 involved the evaluation of outcomes if MTC employed alternative allocation methods. After the Part 1 review of MTC’s various transit funding programs, the federal pandemic relief funds and the Transportation Development Act/State Transit Assistance (TDA/STA) funding programs were selected and evaluated in Part 2 using a set of five alternative allocation metrics and compared to actual MTC allocations. Key findings include: (1) the population-based metric produced the largest increase for VTA’s pandemic relief funds, with VTA receiving 221 percent more than MTC actually allocated in 2020 and 2021, but the San Francisco Municipal Transportation Agency (SFMTA) receiving 64 percent less; (2) the ridership-based metric yielded the smallest amount of VTA pandemic funding, but high ridership operators such as SFMTA would have a 41 percent increase; (3) the population-based metric produced the largest increase in STA funding to VTA but would come at the expense of other transit operators, with Sonoma County receiving 51 percent less; and (4) the ridership-based metric yielded the smallest amount of STA funds for VTA, with 50 percent less funding than actual, while high ridership operators such as SFMTA, would see a roughly 400 percent increase. Thoroughly investigating current and alternative funding allocation methods and policies is critical to understanding their effects on transit agencies and the communities they serve.

Authors: Kiselev V.G. , Sergeev O.A. , Sergeeva S.A. , Komarova E.I.
Published: October 2023

Topological optimization of linearly elastic 2D structures under static and kinematic effects is presented. As an objective function, the compliance of the structure is considered, which is equal to the work of given external forces and displacements on the displacements and support forces caused by them. The design variables are the thicknesses of 2D finite elements. A constraint in the form of equality on a given volume of distributed material within a given design area is taken into account. The optimization method is based on optimality criteria.
The examples consider the topological optimization of a simply supported beam and a cantilever beam under kinematic and static effects.The displacement is given instead of a concentrated force in the middle of simplysupported beam or at the free end of a cantilever beam. The simply supported beam was divided into 150 finite elements along the length and 50 finite elements along the height, the cantilever beam – into 150 finite elements along the lengthand 100 finite elements along the height. Differences between the results of optimization under kinematic effect and the results of optimization under static effect are insignificant. To conduct an experiment on biaxial tensionthe analysis considered a 2D sample consisting of a square test part of constant thickness and a square supporting part, which transmits an external force to the test part. The distribution of thicknesses of the providing part of a given volume was obtained, which minimizes its compliance.Under kinematic effect, the testing machine generates a unit displacement perpendicular to both ends of the specimen and a zero displacement along both edges of the supporting part.Under static effect, the testing machine created a uniform load along the edge of the supporting part in each node. It is shown t hat the sensitivity and the optimization process significantly depend on the type of external effect – static and kinematic.

Published: October 2023

Problematyka odpadów to temat szeroko dyskutowany zarówno na poziomie europejskim jak i krajowym. Niewystarczający udział w strumieniu odpadów tych zbieranych selektywnie oraz zbyt duża ilość odpadów kierowanych na składowiska przy jednoczesnej konieczności wdrożenia przez Polskę koncepcji gospodarki o biegu zamkniętym powoduje konieczność przeanalizowania możliwości dokonania zmian, przede wszystkim na gruncie prawnym. Ich celem powinna być minimalizacja ilości powstających odpadów oraz skuteczniejsze przeciwdziałanie zagrożeniom wynikającym z obecności odpadów w środowisku. Odpadami szczególnymi są produkty lecznicze, powstające zarówno w aptekach jak i gospodarstwach domowych. Niewłaściwie postępowanie z niepotrzebnymi/przeterminowanymi produktami leczniczymi może powodować negatywne skutki zarówno dla środowiska jak i zdrowia człowieka. Problem ten dotyczy również suplementów diety, które na gruncie prawa traktowane są jako produkty żywnościowe pomimo, iż mogą one zawierać związki mogące negatywne oddziaływać na zdrowie oraz na środowisko. Właściwy sposób postępowania z odpadami pochodzącymi z produktów leczniczych i suplementów diety uzależniony jest od prawidłowej klasyfikacji tych rodzajów odpadów.
Celem pracy jest analiza przepisów dotyczących klasyfikacji odpadów pochodzących z produktów leczniczych (zarówno powstających w aptekach jak i gospodarstwach domowych) i suplementów diety oraz problemów prawnych związanych z tą klasyfikacją. Dyskusyjna jest przede wszystkim klasyfikacja odpadów z suplementów diety. Jest to o tyle istotne, gdyż prawidłowa kategoryzacji warunkuje odpowiedni, bezpieczny sposób unieszkodliwiania odpadów (przekształcenie termiczne, składowanie na składowiskach). W pracy wskazano również na problemy w zdefiniowaniu pojęć na styku przepisów dotyczących ochrony środowiska i regulacji odnoszących się do produktów leczniczych. Analiza została ograniczona do odpadów pochodzących z produktów leczniczych i suplementów diety powstających w aptekach oraz gospodarstwach domowych i nie dotyczy odpadów z zakładów farmaceutycznych oraz chemikaliów wykorzystywanych w aptekach do wytwarzania leków recepturowych i aptecznych.
Chronological simulation and Quantitative Evaluation of System Reliability in a Complex Restructured Power System
Authors: Jesan Rodriges , Hassan Zahir
Published: October 2023

Ensuring the provision of high-quality and dependable power supply to customers stands as a paramount responsibility within the realm of power systems. The concept of restructuring the power system emerges as an efficient approach to deliver economically viable and uninterrupted power supply. The assessment of power system reliability hinges on various factors, with the reliability index serving as a pivotal metric, dependent on both system security and adequacy. To enhance the reliability index, strategically locating FACTS devices becomes essential, a task facilitated through power flow analysis with specified constraints, pinpointing the weakest points through Genetic Algorithm-driven fast-acting device placement. The correlation between DG establishment and the reliability index was meticulously calculated, further bolstered by the introduction of a Derated Forced Outage Rate for enhanced performance assessment. In the pursuit of heightened power system reliability, sequential simulations prove invaluable, particularly in minimizing Expected Energy Not Supplied (EENS) and improving overall system reliability. The results obtained through sequential simulations underscore the effectiveness of this approach within bulk electrical systems. The installation of multiple FACTS devices in the system's weakest areas facilitated EENS computation, coupled with the assessment of related reliability indices such as system frequency and system duration. This approach not only enhances system reliability but also promotes the economic operation of both transmission and distribution.The simulation results substantiate the alignment of power system reliability objectives in deregulated power systems with the required standards, advocating for the restructuring of power networks. The reliability assessments, driven by the optimal placement of DGs and FACTS devices, reveal substantial improvements in system reliability, underscoring the pivotal role of these technologies in enhancing overall power system dependability.

Published: October 2023

Community-based tourism (CBT) has become a potential form of tourism in rural areas around the world and in Vietnam, where local communities are the main subject exploiting tourism resources to create tourism products provided for tourists and, the benefits from tourism activities are equally distributed to them. Based on the unique potential tourism resources, local communities and other stakeholders in Ly Son Island (Ly Son District, Quang Ngai rovince) are actively developing the CBT in association with the orientation of tourism becoming a spearhead economic sector, creating a driving force for the socio-economic development of the district. However, in recent years, the CBT development in Ly Son Island has revealed limitations, inefficiencies, and lack of sustainability in exploiting tourism resources as well as product quality. Although researches on sustainable tourism have been quite popular in the world, specific research on sustainable CBT in islands, especially in ones in Viet am, is rarely mentioned. This study used deep interviews, ethnographic fieldwork, and the assets-based community development (ABCD) method to analyze the potential and status of the CBT development in Ly Son Island, thereby suggesting sustainable development orientations from three angles: economic efficiency, improvement of local community capacity, and environmental sustainability.
Japan's perception and use of the soft power in international relations
Authors:   The University of Social Sciences and Humanities, VNU-HCM, Vietnam, Tran Khang Nguyen
Published: October 2023

Power or the ability to influence other actors has always been a topic of great interest in international relations. In the context of globalization with the connection between countries in close correlation and interdependence, the nature of power has changed significantly. According to Professor Joseph Nye (Harvard University), power gradually shifts the focus from the classical form of coercion and bribery to the use of attraction and persuasion. The ability to gain what you want through attraction and persuasion, with cultural, political, and diplomatic values, is called “soft power” by Joseph Nye. By using the concept of the soft power as the research orientation, the article analyzes the case of Japan in achieving positive influences in international relations. Through conducting field surveys and expert interviews, the study provides the analysis on Japan's perceptions and practice in the use of the soft power. Japan has effectively used the internal strength as well as promoted the external advantages to form a solid position of the soft power in the world. From the lessons of Japan's experience, the study offers some suggestive discussions about the development of the soft power for Vietnam.

Authors:   University of Social Sciences & Humanities, VNU-HCM, Vietnam, Nguyen Nhu Thi Quynh
Published: October 2023

The New Year festival (Pithi Chol Chnam Thmay) of the Khmer people in Southern Vietnam is a traditional one, which has undergone changes under the influence of modern society. This paper was based on the survey results of 42 correspondents representing 42 Khmer households in Don Xuan Commune, Duyen Hai District, Tra Vinh rovince to investigate their perception of cultural changes in celebrating the New Year festival. The quantitative and qualitative research result have reflected Southern Vietnam Khmer people's perception of changes in the content, form, and festival audiences, namely that (1) few Khmer people find the changes in the activities of the New Year festival, (2) Khmer people have limited understanding of the significance of the New Year festival activities, (3) the process of transmitting traditional culture values of the New Year festival is one-way, passive, and incomplete, and (4) young Khmer people tend to migrate to big cities for their livelihood, which separates them from the traditional cultural space of the Khmer people. This paper aims to provide the realistic data, contributing to the practical assessment of the economic and cultural life of the Khmer people in Don Xuan Commune, Duyen Hai District, Tra Vinh rovince nowadays as well as offer helpful suggestions on the formulation of ethnic policies and the preservation of the intangible culture of the Khmer people in Southern Vietnam.
Ethnic Consciousness with the assumption of thinking paradigm in cultural issues that ethnic minorities of Viet Nam are facing
Authors:   Faculty of Anthropology, University of Social Sciences & Humanities, VNUHCM, Vietnam, Trần Kỳ Đồng
Published: October 2023

From the viewpoint of anthropology, conducting surveys on ethnic consciousness is not only visually collecting and analyzing anthropological data, but also studying natural factors and history of the mode of production belonging to a particular form of human community, in which, people share the same history of territorial defense, beliefs, customs, a collective personality established and maintained consciously that formed the unique cultural nuances of each ethnic – especially ethnic minorities. The alienation (being alien to oneself) in the consciousness of ethnic minorities in Vietnam is taking place. Nature and spiritualites are transformed into an essence alien to man, into a means of sustaining one's individual existence. Cultural preservation must promote cultural development. However, the space of modern life has caused interruptions in the flow of the memory-history-nation heritage. There should be an alarm that the spiritual time and space of traditional rituals and legends – a unique feature of the connection between culture and the manifestations of ethnic consciousness – are faded away in Vietnam nowadays If we identify culture as spiritual endogenous elements, it will be neccesary to posit a theory shaping ethnic thinking into two paradigms - “preservation for autogenesis” and “accompanying for development” - in order to re-determine the cultural values of ethnic people that need to be preserved.

Does Village Fund Reduce Poverty and Disparity in East Java Province? Evidence from Indonesia
Authors: Suseno Vimbyarno Purbo , Syafitri Wildan , Bintoro Nugroho Suryo
Published: October 2023

From economic perspective, poverty arises as result of lack of access to capital and resources differences as explained in the vicious circle of poverty theory. In addition, differences in each region and various factors then create developed regions and underdeveloped regions. Developed regions are progressing and becoming a magnet for the capital, investment and residents of underdeveloped areas. Meanwhile, underdeveloped regions remain. Statistical data shows that the poverty rate is greater in rural areas than in urban areas. For this reason, the government's policy to overcome poverty and disparity is to carry out development from marginal areas, namely rural areas. With the enactment of Law Number 6 of 2014, the village becomes an autonomous region to be able to regulate dan manage its community including aspects of planning, development, finance, and democracy independently. Since 2015, the government has allocated Village Funds to villages originating from the State Budget in the amount of 10% of and excluding Regional Transfers allocated in the State Budget. The results of the study show that Village Funds significantly reduces poverty, but it has no impact on disparity.

Authors: Finira Dwinita Chika , Kusumah Lien Herliani
Published: October 2023

The Manpower and Transmigration Office, also known as Disnakertrans provides direct services to the community, including the issuance of the AK-I cover letter commonly known as the "Kartu Kuning”. A significant issue has emerged at the Disnakertrans, where the process of obtaining an AK-1 takes more than 20 minutes, surpassing the average time expected by job seekers. Additionally, daily quotas for AK-I issuance are restricted due to Covid-19 regulations. To assess and enhance service quality for AK-I issuance at Disnakertrans Banten Province, a service satisfaction method is imperative. This study employs the Fuzzy Servqual method. The research reveals a noteworthy negative gap in the reliability dimension, particularly concerning two attributes. The first attribute (Question 7) addresses the ability of officers to guide job seekers through the AK-1 application process. The second attribute (Question 8) pertains to the accuracy of officers in entering data according to the specified requirements. These findings underscore the importance of addressing issues related to the reliability dimension, particularly the officer's ability to guide the application process and ensure accurate data entry. By focusing on these aspects, Disnakertrans can make targeted improvements to enhance overall service quality and meet the expectations of service users.
Investigating the Construct of a Listening Test to Assess Pilots’ Comprehension: a Step-by-Step Project for Test Developers
Authors:   Carleton University, Garcia Angela Carolina de Moraes
Published: October 2023

Pilots and air traffic controllers must demonstrate their ability to listen and speak the language used in radiotelephony communications demonstrated by completing a language test. In this context, it is crucial to assess both interactive listening, when listening occurs together with speaking, and listening in isolation, when there is no speaking or interaction. The purpose of assessing listening in isolation is to reduce the influence of skills that are not relevant to the construct, that is, to minimize construct irrelevant variance (S. Messick 1994). This article describes a project that can be followed by test developers to address the initial step in the development of a test to assess pilots’ listening in isolation: the construct definition. The project is framed within an interactionalist perspective wherein a test construct is defined based on a combination of the abilities that those taking the test should have and the tasks that they should be able to perform (L. Bachman 2007). It is also informed by the work of L. Bachman/ A. Palmer (2010) and the framework proposed by U. Knock/ S. Macqueen (2020) for the development of language assessments for professional purposes. The project outlined in this article may also be of interest to test developers who wish to investigate different constructs of aeronautical English tests, as well as those involved in the development of other types of language assessments for professional purposes.
Aviation English Assessment for Military and Civil Pilots in Brazil: Similarities and Differences
Authors:   São Paulo State University, Barbosa de Carvalho e Silva Ana Ligia
Published: October 2023

Language proficiency assessment for pilots is a topic of potential interest for applied linguists and aviation professionals in general. Despite the growing number of investigations about this topic in the Brazilian civil aviation context (A.L. Monteiro/ N. Bullock, 2020, A. Garcia 2015, P. Tosqui-Lucks/ M. Prado 2020, A. Pacheco 2019), fewer similar studies are found in the Brazilian military scenario (A.L.B.C. Silva, 2016, 2022, M. Bruno 2018). With this difference in mind, this study presents an overview of the instruments being used to assess Aeronautical English proficiency for civil and Air Force pilots in Brazil.This study followed a qualitative approach by means of a bibliographic review and documental analyses. Results of this study show that the same instruments are used to assess English language proficiency for all Air Force pilots in Brazil, despite their varying needs, whereas a different instrument – the Santos Dumont English Exam (SDEA) – is used for civil pilots. Similarities and differences in both assessment scenarios have been highlighted to better understand the theoretical constructs assessed in each test. As a contribution to the fields of Applied Linguistics and English for Specific Purposes (ESP), this study allows different stakeholders to have a clearer and better understanding of Aeronautical English assessment for pilots in Brazil. This can help ensure that best practices are highlighted, and improvements implemented, which, as a result, could lead to more efficient and effective communications and safer skies for everyone.

Published: October 2023

The paper presents best practices necessary for constructing mandatory tests for aviation/aeronautical purposes. Based on the TEAP test, we will show an example of the test form and content in accordance with the ICAO recommendations. We will analyse all the components and talk about their functions. The TEAP test has been used in Ukraine since November 2007. The Test specifications were piloted on 1114 Ukrainian ATCOs during the years of 2007–2009. The TEAP has been authorised by Ukrainian Civil Aviation Authority as a test to be used in Ukraine for licensure purposes of both controllers and pilots. In this paper, the language construct is considered as a benchmark for all aspects of ICAO language proficiency requirements implementation through aviation personnel teaching and testing. According to the Dictionary of Language Testing (1999), a ‘construct’ is defined as an ability or sets of abilities that will be reflected in test performance, and about which inferences can be made on the basis of test scores. The Test practices will be presented on a large-scale format including examiners and raters’ functions which should be viewed as crucial factors to provide the best test qualities – validity, reliability and practicality. Therefore, the TEAP specifications will be presented with the reference to the ICAO Chapter 6 provisions and the roles of examiners/raters as part of the testing system.

Step voltage is the voltage on both legs affected by living beings (human and animal) due to be in electrified areas. This current flow can occur due to lightning, the voltage is leaking into the ground, under-voltage wires disconnected and touch the ground, the difference between the value of earthing resistance to earth with one another and so on. At a certain value voltage step can be harmful for living beings. Earth resistance value, the planting depth electrodes, electrode shape, and site conditions will determine the performance of earth to earth, among others, affect the value of the voltage step that occurs around the point of grounding. This study intends to test the security level of the fourth point of grounding, which has been prepared by different methods, the voltage step that occurs in the vicinity. The results showed, the most dangerous area is closest to the fault location with a radius of 0-10m. Mesh method produces a voltage step lower than the method of Rod.

Key words: Hazardous area, rod method, mesh method, the voltage step

Tegangan langkah adalah tegangan yang terkena pada kedua kaki mahkluk hidup (manusia dan hewan) akibat berada pada daerah yang dialiri arus listrik. Aliran arus ini dapat terjadi akibat adanya petir, tegangan yang bocor ke tanah, kabel dalam kondisi bertegangan terputus dan menyentuh tanah, perbedaan nilai tahanan pentanahan antara titik pentanahan satu dengan lainnya dan sebagainya. Pada nilai tertentu tegangan langkah dapat membahayakan bagi makhluk hidup. Nilai tahanan pentanahan, kedalaman penanaman elektroda, bentuk elektroda, dan kondisi lokasi pentanahan sangat menentukan kinerja titik pentanahan, antara lain mempengaruhi nilai tegangan langkah yang terjadi di sekitar titik pentanahan. Penelitian ini bermaksud untuk menguji tingkat keamanan keempat titik pentanahan, yang telah dibuat dengan metode berbeda, terhadap tegangan langkah yang terjadi di sekitarnya. Hasil penelitian menunjukkan, daerah yang paling berbahaya adalah yang terdekat dengan lokasi gangguan dengan radius 0-10m. metode Mesh menghasilkan tegangan langkah lebih rendah dibandingkan dengan metode Rod.

Currently, the use of chemical inhibitors has been limited because it can pollute the environment. In line with the concern for environmental health, this research studied the effectiveness of corrosion inhibition of mild steel in 1M HCl solution by extracts of black rice husk. Results obtained from the method of weight loss and potentiodynamic polarization shown that extracts of black rice husks act as mixed-inhibitor effectively in an acidic environment, where the cathodic inhibition effect is more dominant. Inhibition efficiency of black rice bran extracts was increased with increasing concentrations of inhibitors, and achieve optimum efficiency value of 91% with the addition of 2000ppm extract on day six.

Keywords: Black Rice Husk, Corrosion inhibitors, Mild Steel, 1M HCl.

Geopolymer concrete is a kind of concrete that does not use portland cement as binder but utilizes natural material that contents silica as fly ash, rice husk ash, etcetera.The used material in this research is fly ash from PLTU Suralaya. The alkaline activator is needed for making geopolymer concrete in order that it fastens reaction of polymerization and reacts Al and Si elements exist in fly ash. Solution in viscosity 11 Molar is used with comparison in weight of sodium hydroxide and sodium silicate 1:2 and between water and fly ash ratio 0,2. Maintenance method is submerged in water, put into steam (temperature 60oC, in 24 hours) without maintenance (reference), then put into the oven (temperature 250oC, in 24 hours). The result of initial setting is found that the time is faster compared to cement concrete, while the unit weight is no significant difference. The result of experiment in compressive strength of concrete that is maintened in the steam shows stability, while reference concrete increases in compressive strength. For the submerged concrete in water for 28 days, the compressive strength decreases, and the concrete that is maintened in oven has lowest compressive strength compared to others. So the result in compressive strength of concrete that is maintened in the steam and reference concrete have the highest tensile strength.

Key Words : concrete, geopolymer, initial setting, unit weight, compressive strength, tensile strength
