Provincializing Empire: Ōmi Merchants in the Japanese Transpacific Diaspora
Authors: Uchida Jun
Published: February 2023

Provincializing Empire explores the global history of Japanese expansion through a regional lens. It rethinks the nation-centered geography and chronology of empire by uncovering the pivotal role of expeditionary merchants from Ōmi (present-day Shiga Prefecture) and their modern successors. Tracing their lives from the early modern era, and writing them into the global histories of empire, diaspora, and capitalism, Jun Uchida offers an innovative analysis of expansion through a story previously untold: how the nation’s provincials built on their traditions to create a transpacific diaspora that stretched from Seoul to Vancouver, while helping shape the modern world of transoceanic exchange.
IMPACT OF ERBIUM-DOPED ZINC TELLURITE GLASSES ON RAMAN SPECTROSCOPY, ELASTIC AND OPTICAL PROPERTIES

Published: February 2023

In this study, the melt-quenching technique was employed to fabricate a series of zinc tellurite glass systems doped with erbium oxide. At room temperature, raman spectroscopy, elastic and optical measurements were utilized to analyse and report the result of prepared glass samples. The raman spectra displays the existence of structural units of tellurite networks such as trigonal bipyramid and trigonal pyramid. The elastic parameters including Debye temperature, mean velocity, acoustic impedance and softening temperature provide a fluctuating trend against the concentration of erbium oxide. The increment and decrement of these parameters can be explained by the ‘competition’ of non-bridging and bridging oxygen atoms. In the aspect of optical approach, the oxide ion polarizability, optical basicity and metallization criterion display more than one trend. Again, this can be correlated to the presence of erbium oxide which affects the vicinity in the glass matrix.

In this paper, Ag2ZnSnS4 (AZTS) thin films are prepared by depositing them on glass substrates at a temperature of (400 ºC) by chemical spray pyrolysis method, using 0.02 M of silver nitrate AgNO3, 0.01 M of zinc chloride ZnCl2, 0.01 M of tin chloride SnCl2.2H2O, and different concentrations of thiourea (SC(NH2)2) as source precursors. The structural, elemental analysis, optical, and electrical properties were investigated by XRD diffraction, Raman Spectroscopy, FESEM, UV-Vis. spectroscopy, and Hall effect technique. The results of XRD diffraction show that all films have a tetragonal stannite structure and pirquitasite type. The XRD diffraction results were confirmed by using the Raman spectrophotometer, where the results showed the emergence of the main peak with the highest intensity of the AZTS compound at the two sites (347, 348 cm-1 ). The FESEM results demonstrated the presence of micro particles with spherical shapes. The elemental analysis (weight and atomic percentages) of all samples is investigated using EDS technique. The optical energy band gap was proven to have a value ranging between (2- 2.08) eV with a high absorption coefficient (α ≥104 cm-1 ). On the other hand, electrical tests through the Hall effect of AZTS thin films show that they have an electrical conductivity of N-Type.

Novel 2D/2D structural nanocomposites of g-C3N4/MoS2 with high tribological properties was fabricated through a facile one-step process. The tribological properties of the as-prepared g-C3N4/MoS2 as additives in the HVI500 base oil are evaluated by an UMT-2 multi-specimen tribo-tester and the topography of worn scars was obtained using a common SEM,which indicates the minimal friction coefficient (~0.10) and wear rate (3.86×10-5 mm3 /Nm) and demonstrate the accentuating improvement in reducing-friction and anti-wear properties. The enhanced tribological performance of base oil can be ascribed to the combination of g-C3N4 and spherical-like MoS2 to share the role of synergistic lubrication. More importantly, our work provides a fresh insight into designing lubricating oil additive and extending the 2D/2D structural nanocomposites.

The NiS2 SA was successfully fabricated by uncomplicated and cost-efficient ultrasonic liquid exfoliation and follow by incorporating into polyvinyl alcohol (PVA) polymer to form a NiS2-PVA composite thin film SA. Qswitched pulse operation was obtained at low threshold pump power of 25.6 mW. The Qswitched EDFL operated at 1564.8 nm with repetition rate tunable from 48.1 kHz to 85.5 kHz when the pump power is varied from 25.6 mW to 71.5 mW. The minimum pulse width and highest achieved single pulse energy are 5.85 µs and 114.7 nJ, respectively at pump power of 71.5 mW. This result shows that the NiS2 has immerse potential for photonic applications.
Young Adults and their Parents: The (Mis)understandings that Construct Mental Illness
Authors: Patterson Sydney
Published: February 2023

While public awareness about young people’s mental health has been on the rise, the context in which it is studied has many gaps. Adolescent mental health is often studied within the context of family relationships but the same is not true for young adults over 18 years old. Drawing on interviews with young adults who have mental illness and their parents, I found that the parent-child relationship is a relevant context in which ideas about what mental illness is are constructed. Through the conscious presentation of self within the unique expectations of this relationship and the feedback from parents or children, young adults construct definitions of mental illness which guide their ideas of self and actions in the relationship. By considering this specific relationship and life stage, I hope to contribute to a more specific understanding of the social construction of mental illness and to highlight its practical implications in the lives and relationships of young adults.

En Colombia el 19,8 % de las personas con discapacidad reporta cuatro o más deficiencias, lo que se asocia a mayor necesidad de apoyo de un tercero para realizar las tareas diarias. El 37,7 % de la población registrada con discapacidad depende permanentemente de un cuidador; éste generalmente es mujer (75,1 %), del mismo hogar (83,7 %) y sin remuneración, cifras que coinciden con análisis internacionales relacionados también con la economía del cuidado. Lo cual hace necesario analizar el alcance del marco legal y constitucional de los cuidadores familiares e informales de personas con discapacidad funcional, teniendo en cuenta que la Diversidad Funcional se ajusta a una realidad en la que una persona trabaja de manera diversa a la mayoría de los miembros de una sociedad, lo cual hace que dependa de un cuidador.

The main instruments of state support for the development of the agro-industrial complex
Authors: Prodan Tatiana
Published: February 2023

Introduction. The formation and functioning of economic relations in Russia according to the principles of the market system of management requires attention to the agro-industrial complex, on the activities of which the country's food security and the growth of its export potential directly depend.
Materials and methods. At the present stage, there is a situation when, for the further successful development of this industry, it is necessary to revise the emphasis of state financial support. The practice of providing state support indicates the need for its production in various directions: economic, financial, legal, investment, budgetary, with the definition of appropriate implementation tools. However, domestic practice focuses only on financial and economic, ignoring all other types.
Results. In modern conditions, questions arise about the expediency, content and number of budget programs aimed at supporting the agricultural sector of the economy and, as a result, their impact on the development of rural areas.
Discussion. Every year the situation becomes more and more difficult when planning state support for the development of agriculture. The incomplete formation of the management system also has a negative impact on the production of the agricultural sector. The process of state regulation of agricultural production is based on economic support for the incomes of agricultural producers. This is due to the fact that they must provide the necessary level of profitability in conditions of unfavorable market conditions, as well as be financially interested in conducting agricultural production in such a volume, quality and range of products that are beneficial to consumers to ensure the social stability of society.
Conclusion. In the presented article, the main instruments of state support for the development of the agro-industrial complex at the present stage are considered and analyzed. Based on the research, an assessment of the effectiveness of the use of state support measures for agricultural production was carried out and directions for their improvement were formulated.

Formation of an integrated approach to the selection of effective building materials for the regions of the Far North
Authors: Pogoreltseva Ekaterina , Politi Violetta
Published: February 2023

. The priority direction of the stabilization of the Russian economy is the maintenance and development of the northern territories with unique minerals. One of the socio-economic tasks that make it possible to solve national problems is to retain the population in the northern territories and simultaneously attract new specialists to implement knowledge-intensive and high-tech projects that contribute to the development of the country as a whole. Therefore, social policy aimed at the reconstruction and new construction of residential, social and infrastructure facilities should have a comprehensive justification for the choice of such construction resources that would meet the challenges of the current time — progressiveness, innovation, uniqueness, economy.
When developing a feasibility study of projects, it is necessary to evaluate the unique characteristics of building materials that allow solving the problems of construction and subsequent operation in extreme climatic conditions of the North, taking into account the required recycling of construction waste.
According to the authors, the determining criteria for the selection of thermal insulation materials are low thermal conductivity and vapor permeability, service life, duration of the overhaul period, technogenic and environmental safety and the cost of operation of the facility. However, in the feasibility study of the choice of building material, the key criterion is the current selling price of the supplier-manufacturer, and not technical, technological or environmental parameters reflecting unique consumer properties that affect comfort, microclimate and the cost of subsequent operation.
Therefore, the authors of the study believe that an exceptionally comprehensive interval-time approach is required to conduct a feasibility study of the choice of an effective thermal insulation material for difficult climatic conditions, which consists in taking into account long-term environmental factors of the habitat and operational technical and economic factors.
Opportunities for economic growth of regional economic systems in the context of the implementation of the concept of balanced development
Authors: Belov Valeriy
Published: February 2023

One of the goals of the economic policy of most countries of the world is to increase the pace of economic growth. The successful socio-economic development of national economies and regional economic systems largely depends on the achievement of this goal. Many scientists-thinkers of the past, from T.R. Malthus and A. Smith to modern scientists-economists R.E. Lucas and P.M. Romer (Nobel Prize laureates in Economics) addressed this problem, offered their solutions. This article retrospectively analyzes the models of economic growth of the twentieth century by such
well-known scientists as R. Harrod, E. Domar, R. Solow, T. Swan, K. Arrow. The author comes to the conclusion that, theoretically, there have been significant changes regarding views and approaches to solving issues of increasing the economic growth of national economic systems. In the scientific environment, new growth theories will prevail, in which the emphasis is on endogenous factors. At the same time, economic growth is closely interrelated with the economic development of regional economic systems, which, in the context of the implementation of the concept of balanced development, strive for sustainability. In turn, sustainable development, at its core, when conducting production and economic activities, provides for the leveling of negative consequences (externalities) such as excessive consumption of natural resources, harm to the environment, destruction of the ecosystem. As a solution, the author proposes the implementation of the "green" economy model. It is concluded that in the long term, in the context of the implementation of the concept of balanced development, economic growth of regional economic systems becomes possible, and new growth theories in which endogenous factors are dominant can serve as a theoretical foundation. The article is part of the author's dissertation research.
Applying artificial intelligence to the internet of things
Authors: Masserov Dmitriy , Masserov Daniil
Published: February 2023

The paper shows that the functioning of the Internet is constantly transforming from the Internet of Computers to the Internet of Things. Moreover, according to the authors, massively interconnected systems, also known as cyber-physical systems, arise from the integration of many aspects, such as infrastructure, embedded devices, intelligent objects, people and the physical environment. The ubiquitous "Internet of Everything on a Smart Cyber-Physical Earth" is what civilization is heading toward and the authors agree on. "The Internet of Things" and cyber-physical systems combined with "data science" could be the next "smart revolution". This raises the problem of processing huge amounts of data with much less current computing power. Research in data science and artificial intelligence seeks to provide an answer to this pressing problem. Thus, the authors indicate that the "Internet of Things" with artificial intelligence could be a huge breakthrough. The authors believe that it is not just about saving money, smart things, reducing human effort, meeting the ever-growing needs of people, but about much more — facilitating human life. The authors considered serious problems, such as security and ethical issues that will continue to be of concern to the Internet of Things. The main problem, according to the authors, is not how deeply the Internet of Things connects with artificial intelligence, but how ordinary people perceive it — as a benefit, a burden or a threat.

Authors: Makarova Vera , Vasilevskaya Eva
Published: February 2023

The relevance of the topic of the work lies in the consideration of one of the most promising methods of gentle nature management — ecological tourism. Special attention is paid to the state nature reserve "Bureinsky", namely to the assessment of anthropogenic factors that can lead to a decrease in the number of visitors to the reserve. The article describes in detail the technique of "estimation of current capacity" and its practical application on the territory of the ecological trail "At the Sources of Burea" in the State Nature Reserve "Bureinsky". An important sphere of activity in the sustainable development of the state and the development of ecological tourism is the provision and preservation, restoration of the environment in the process of recreational use and minimization of possible negative consequences. The use of this technique allows you to regulate the level of negative anthropogenic impact on the natural environment and create optimal conditions for visiting the reserve in a short time without resorting to the involvement of outside specialists. The article offers a list of the most significant factors of anthropogenic impact, taking into account their weight in the impact on natural territories, based on which the number of visitors to the route under consideration was calculated. The scientific novelty of the study consists in the correction of the method of calculating the recreational capacity to prevent the degradation of the natural environment of hard-to-reach protected natural territories, which will allow the development of ecological tourism in hard-to-reach protected natural territories in the context of sustainable development. The authors consider possible prospects for the development of ecological tourism in the reserve and offer options for the distribution of the flow of tourists, which can contribute to the sustainable development of modern society, in which future generations will inherit from us the world around us with parts of the earth's surface without any changes.
The purpose of this article is to calculate the maximum permissible recreational capacity of the trail "At the Sources of Burea" on the territory of the State Nature Reserve "Bureinsky".
Cadmium pollution of environment by the use of solar cells: a systemic review of the problem
Authors: Mikhailenko Anna , Ruban Dmitry
Published: February 2023

Use of solar cells contributes to ecologization of the energy sector of economy, but also requires taking into account various influences on environment. Particularly, many of them utilize cadmium (as cadmium telluride), which triggers concerns of possible pollution by this toxic heavy metal. This article summarizes and systematizes a significant amount of information, which allows evaluating such a pollution. Methodologically, this work is based on bibliographical survey and examination of the content of articles in the leading domestic and foreign editions on the considered problematic. It is established that the problem of cadmium pollution of environment by the use of solar cells has generally been formulated in the contemporary science, but as hypothetical to significant degree, and its treatment is distinguished by remarkable incompleteness. The authors show that in the light of the earlier conducted research, pollution of environment (also industrial) can take place together with cadmium extraction, production of solar cells, their use and utilization, the facts of which are known. The scale of this problem is currently difficult to establish, but its under-study itself creates risks of its large-scale appearance in the nearest future. Sometimes, scientists raise the question of replacing cadmium-bearing materials by those ecologically more “clean”. In this regard, a question is posed about whether such a replacement would diminish interest to correct utilization of already used cells, mass accumulation of which as waste makes pollution inevitable. The attention is also paid to the fact that even if solar energetic itself diminishes cadmium flux to environment via replacement of “traditional” sources of energy, changes in the geography of production of the latter is able to extend the appearance of the considered problem.
Prospects for the development of the waste management industry within the framework of the Industry 4.0 concept
Authors: Iordanova Anastasia , Yushin Vasily , Podkolzin Pavel , Gladilin Daniil
Published: February 2023

The article is devoted to the analysis of the potential development opportunities of the waste management industry with the introduction of digital technologies. The main technologies already developed, as well as promising research in this industry are considered: robotics, artificial intelligence and neural networks, the Internet of Things, cloud computing, data analysis. Specific examples of the use of the described technologies in the field of waste management, their advantages and disadvantages are given.
The authors analyzed waste management processes that are transformed within the framework of the Industry 4.0 concept: logistics of solid municipal waste (MSW), document management in MSW management and the process of sorting waste coming from enterprises and the population. The analysis of the main driving forces and barriers to the development and implementation of Industry 4.0 technologies in the field of waste management is presented. It is revealed that the main driving forces are: an increase in the amount of waste generated, consumer expectations, price pressure, urbanization, climate crisis, business models. The main barriers are: large investment costs, security issues, the lack of a digital ecosystem and the lack of digital literacy among the population.
In addition, the article discusses the possible consequences of the use of digital technologies in the field of waste management. These consequences are primarily associated with an increase in energy consumption in order to create and develop digital technologies, as well as the use of additional resources for the production of infrastructure, computers, various robots and other devices. Important is the fact that any infrastructure has a life cycle, and eventually becomes a waste itself.
Assessment of the functioning of the regional system for handling consumption and production waste
Authors: Kutyshkin Andrey
Published: February 2023

The paper considers the evaluation of the effectiveness of the regional system for handling consumption and production wastes of the Khanty-Mansiysk Autonomous Okrug — Yugra (KhMAO-Yugra). The aim of the work is to develop a comprehensive assessment of the operation of this system using a quantitative characteristic of the proximity of the normative and actual modes of its functioning. These modes are specified by ordered sequences of indicators, which are identified when the system under consideration is represented as an "input-transformation-output" model. As a research method, an ordinalistic approach to the formation of structural and functional models of systems was used. The directly normative ordering of the identified indicators, called the dynamic norm, is considered as a non-metric structural model of the system, taking into account the systemic relationships between the indicators, as well as the dynamics of their values. The degree of discrepancy between the normative and actual modes of system functioning is determined on the basis of a comparison of the corresponding adjacency matrices. Along with this, the actual ordering of the indicators of the dynamic standard can also be considered as a factorial model of the system's functioning. Factor analysis of such a model allows you to identify the degree of change in the values of indicators directly on the functioning of the system. Estimates of the regional system under consideration, obtained using the proposed dynamic standard on the basis of statistical data characterizing the circulation of consumer and production waste in Khanty-Mansiysk Autonomous Okrug-Yugra for the period from 2010 to 2020, characterize the rather volatility of its mode of operation and significant differences from the normative one. The results obtained were compared with the calculated values of the modified decapping coefficient, which were determined on the basis of the dynamics of the values of the gross regional product and the volumes of consumption and production waste that are annually generated in the region.

Published: February 2023

Improving the efficiency of using the natural resource potential in the extreme conditions of the North is an important condition for the balanced development of socio-economic systems. The key aspects of rational nature management are the maximum extraction of useful substances and their inclusion in the production process, as well as the reduction of anthropogenic pressure on natural ecosystems. This study is devoted to the study of the impact of the use of artificially improved soils based on pulp and paper industry waste on the socio-economic development of the regions of the North as one of the methods of rational environmental management. The relevance of the study is also due to the need to increase the role of the agricultural sector in the economy of the northern territories and improve the supply of the population with fresh, biologically valuable food. Based on the analysis of a significant amount of scientific literature and legal documents of strategic planning and project management, the authors reveal the types of social, economic and environmental results of the use of artificially improved soils based on pulp and paper industry waste and systematize them in terms of national, territorial, sectoral, corporate and personal influence. The developed methodological recommendations include the principles on which the methodology for assessing the socio-economic effectiveness of the introduction of artificially improved soils should be based, an algorithm and a system of evaluation indicators that reflect the social, economic and environmental effectiveness of the use of this category of soils for both the agricultural sector and the pulp and paper industry are proposed industry. The developed recommendations can be used to develop regional plans and programs in the field of environmental conservation and agricultural development and regulation of agricultural and food markets.

Published: February 2023

The current situation associated with geopolitical changes and the destruction of traditional supply chains in the vast majority of sectors of the economy, not only in Russia, but also in a number of countries, has led to a new reading of issues related to the search for new sources of resources to support existing production processes.
The solution of this complex task will be aimed at meeting the growing needs in the face of a growing shortage of resources and minimizing environmental consequences. In a systemic sense, the development vector aimed at more efficient use of initial resources has another, no less important effect — stimulating innovation, creating new jobs, developing a circular economy based on recycling and its more advanced form of upcycling.
The purpose of this article is to develop the basic provisions of the model for the optimal choice of directions for the use of waste (the recycling model based on the principles of "3R" and zero pollution — "Zero Waste") in the sectors of material production of the regional economy. The analysis of the dynamics of waste accumulation, including the morphological composition of municipal solid waste, made it possible to identify the main areas of generation of secondary resources in the regional economy and propose an approach to building a matrix for the optimal use of various types of recycling in the sectors of material production. Based on the author's approach, which consists in using a matrix method for determining the most efficient ways of waste processing for consumer industries, the article proposes a toolkit that allows you to determine the priority vectors for the development of business activity in the regional economy for the use of secondary material resources.

In Chinese, there is such a term as "harmony of the five tastes". "Harmony of five tastes" is the highest degree of harmonization of the taste qualities of a dish in traditional Chinese cuisine. The "Harmony of the Five Tastes" theory was first formed about 3000 years ago and was revered as one of the philosophies that govern the daily lives of people during the "Spring and Autumn" and "Warring States" eras. The Western Zhou Dynasty (1046–771 B.C.) had a court system of training "imperial nutritionists" who were responsible for overseeing the health and nutrition of the court and members of the royal family. "Harmony of the Five Tastes" was closely intertwined with the flow and change of seasons. "Harmony is achieved by imparting refreshing sourness to the dish in spring, tart bitterness in summer, spicy pungency in autumn and brackish intensity in winter, combined with notes of mild sweetness out of season" was a common notion shared by the social elite living some twenty centuries ago. As a dietary system, it was used not only at the court of the Zhou Dynasty, at that time these ideas were shared by aristocrats in all corners of China. And by the end of the Warring States period (around 221 B.C.), the common people of China had already developed a deep understanding of the philosophy of taste harmonization. Thus, we see that the theory of the "Harmony of the Five Tastes" has been formed over the years, based on the experience of using various methods of cooking, and reflecting the Confucian ideals regarding food as part of the meal.
Assessment of the competitive advantages of composite materials in building structures

Published: February 2023

The article presents the results of a study of the domestic market of building composite materials. An increase in research work and the development of the production of composite materials were noted. The authors revealed an increase in the activity of their use in certain types of construction. However, certain difficulties in making decisions at the stage of design and engineering development due to the high cost of composite materials are also identified and described. Therefore, the authors of this study focused on the significant competitive advantages of the studied innovations for the construction industry. The authors also proposed a new fundamental approach to conducting an economic assessment of the effectiveness of the use of innovative building materials using composites as an example. The advantages and various effects arising from the use of composite materials are revealed. As proof, the article provides a calculation of the economic effect achieved in the case of setting the value of the investment project planning horizon equal to the normative average service life of the structure. The effect is achieved in the process of long-term operation due to the increase in the period between repairs and the absence of costs for certain types of construction, repair and maintenance work. An assessment of the import dependence of the construction industry by type of activity "production of composite materials" was carried out. The authors note a shortage of personnel, dependence on imported equipment for the production of composites, and a shortage of their own raw materials. However, the situation in the composite industry is not critical. Thus, an increase in demand from consumers of products, the development and support of new import-substituting manufacturers, the development of a raw material base with the support of the state can solve this problem
3D Urban design based on geographic information technologies
Authors: Kozeeva Olga
Published: February 2023

The urban geographic information system includes a wide range of different types of complex data collected from various sources and provides a solution for city planning, architectural and construction design. The complex structure of the city determines the complex nature of information models and data flows in them. In order to increase the efficiency of existing processes in various areas and directions of urban space planning the state-of-art digital technologies are widely used. The article describes geographic information system that forms a multi-level urban space modeling environment combining data from heterogeneous sources, so it make it possible to reduce time costs for designing and improvement of urban space. The implementation of such a system implies the use of modern digital technologies that capture the geographic information of objects and the development of algorithms for multi-criteria assessment of the generated alternatives for the location of urban objects and infrastructure facilities. The purpose of the work is to increase the efficiency of primary engineering and construction surveys based on geoinformation technologies, which are widely used to solve various problems including preventing environmental issues caused by industrial activity. One of the key features of the system is the accounting of underground utilities, which makes it possible to form a comprehensive assessment of the location of buildings and structures while ensuring accuracy that meets the requirements of engineering and construction surveys, due to modern photogrammetry methods, which resulted in a three-dimensional model of the city. Also, the multi-level nature of the model allows one to choose the location of objects, satisfying the conditions for the inclusion of new objects in the existing infrastructure in terms of the availability of utilities, as well as the context of the urban environment
Dudley Bulmer’s Artefacts as Autobiography
Authors: Wood Michael
Published: February 2023

During a visit to Yarrabah in 1938, Norman Tindale, then working for the South Australian Museum, collected and documented a number of artefacts given to him by Dudley Bulmer, who was originally from Starcke River, north of Cooktown. This paper uses Tindale’s notes on these artefacts to show how Bulmer sometimes inscribed aspects of himself into his artefacts by combining events from his life with representations of Ancestral beings that were important in ceremony. Partly reflecting the power of the state to restrict his freedom, a feature of Bulmer’s presence in his artefacts is his absence from his homeland. I argue these elements make some of Bulmer’s artefacts inscriptive equivalents to the life story genre of Indigenous writing.
The Politics of Time: Hermann Klaatsch in the Wet Tropics and the fate of his ethnographic collection in Europe
Authors: Erckenbrecht Corinna
Published: February 2023

This article examines the scientific and political background and the multiple changes in ownership of the Aboriginal artefacts from Australia collected by the German physical anthropologist Hermann Klaatsch. Originally, Klaatsch travelled to Australia in 1904 in search of the origins of humanity. However, the lack of evidence for the ‘Out of Australia’ theory and the requests by German Museums of Ethnology to collect artefacts for their institutions led to Klaatsch becoming a full-time collector of cultural artefacts, especially during his time in the Wet Tropics. He inscribed the artefacts and sent them to Germany in several shipments to various museums where they were later re-united, displayed and redistributed. Upon his return to Germany in 1907 Klaatsch was appointed professor of anthropology at Breslau University. He took there a portion of his artefact collection for his own teaching and study purposes. Due to political changes in central Europe after the Second World War, this collection was transferred to Warsaw, Poland, in 1953. New ownership insignia were applied while others were (partly) erased. Through these transformations the artefacts became encoded with a rich history and new meanings. A detailed study of Klaatsch’s historical documents allows cross-referencing of the artefacts to the original localities and circumstances of their acquisition. Thus, more than one hundred years after first being collected, the artefact transactions and property claims can be re-assessed.
The Kew’s "World Checklist of Vascular Plants" and its relevance to the knowledge of the flora of Mexico
Authors: Murguía-Romero Miguel , Ortiz Enrique , Serrano-Estrada Bernardo , Villaseñor José Luis
Published: February 2023

Background: The 8th version of the "World Checklist of Vascular Plants" (WCVP) was recently published under the coordination of the Royal Botanic Gardens, Kew. It consists of a list of taxonomic names of species, genera, and families of vascular plants representing the most comprehensive and integrated list available today.

Questions: How many accepted species does the WCVP include? Is the quality of the included information acceptable? How has the publication of worldwide species names evolved over time? Does the checklist include the species recorded for Mexico?

Studied species: Worldwide species of vascular plants included in the WCVP.

Study site: Worldwide and Mexico.

Methods: A database was created based on the WCVP to answer the research questions. The number of genera and species by taxonomic status (accepted and synonyms) was quantified, some information quality tests were carried out, and the potential number of undiscovered species in the world was estimated using non-parametric techniques.

Results: The WCVP contains 1,233,172 names, of which 418,737 are accepted. It is estimated that around 25 % more unknown species remain to be discovered in the world. The quality of the information contained in the WCVP is quite reliable and complete; only 3 % of Mexican species are not included in the WCVP.

Conclusions: The WCVP synthesizes current taxonomic knowledge in an integrated manner and is useful for systematic and automated analyses. At the country level, at least for Mexico, it stands as an important reference source when attempting to understand and evaluate floristic knowledge.
