The nature and degree of human modifications of humid tropical forests in Amazonia have been widely debated over the past two decades. Many regions provide significant evidence of late Holocene anthropogenic influence by settled populations, but the antiquity of human interventions is still poorly understood due to a lack of earlier archaeological sites across the broad region, particularly pertaining to the mid-Holocene. Here we report on Amerindian occupations spanning the period from ca. 6000-3000 BP along the middle Berbice River, Guyana, including early evidence in Amazonia of cultural practices widely considered indicative of settled villages, notably terra preta or “black earth” soils, mound construction, and ceramic technology. These more settled occupations of the mid-Holocene initiated a trajectory of landscape domestication extending into historical times, including larger-scale late Holocene social formations. Collaborative research with local indigenous communities, including archaeological excavations, landscape mapping using kite based aerial photography, and three-dimensional photogrammetry, was designed to promote the decolonization of archaeological knowledge production and encourage indigenous ownership of Amerindian history and cultural heritage in Guyana.

Advanced micro- or macro-systems are in some cases made with multilayer ceramic technology. Low-Temperature Co-fired Ceramic (LTCC) technology is considered as one of the more suitable technologies for the fabrication of ceramic micro-systems that integrate screen-printed, thick-film electronic components as well as three-dimensional buried structures, for example, cavities and channels. One of the applications is a ceramic combustor. The chemical energy of the fuel is converted into thermal energy in a chemical micro-combustor through a burning process, while the accompanying high temperatures and, frequently, high pressures impose harsh conditions on the combustor structure. Therefore, the combustor must be carefully designed not only from the functional, thermal and chemical points of view, but also with respect to the mechanical strength. The combustor device was prepared by laminating of Du Pont 951PX LTCC green tapes. The fabricated 3D LTCC structures with buried cavities and channels including two inlets (for fuel and air), the evaporator for the fuel, the mixing system of the channels (for mixing the evaporated fuel and air), the distribution channels and eight microburners were realized. The main parts are eight micro-burners realized as buried cavities. In the burners a platinum-based catalyst was deposited to assist the oxidation, i.e., the burning, of the methanol with the air. Thickfilm, platinum-based heaters and temperature sensors are incorporated within the structure. The device was tested with different flow rates of liquid methanol (1 ml/h to 5 ml/h) and air (7 l/h to 15 l/h). The obtained temperatures were between 250°C and 450°C.

There are minimally 370 million Indigenous people in the world. The term Indigenous was not used to identify human groups until recently. Indigenous people are often identified as the First People of a specific regional area. Indigeneity as applied to First People came into use in the 1990s, as many colonized communities fought against erasure, genocide, and forced acculturation under colonial regimes. An often-cited definition of Indigenous peoples is one by Jose Martinez Cobo, special rapporteur for the UN Sub-Commission. Cobo’s 1986 report was completed for the United Nations Economic and Social Council, Commission on Human Rights, Sub-Commission on Prevention and Discrimination and Protection of Minorities, thirty-fifth session, item 12 of the provisional agenda, titled, “Study of the Problem of Discrimination against Indigenous Populations.” Cobo described Indigenous people, communities, and nations as groups that have a “historical continuity with pre-colonial societies” within territories they developed, and as communities that “consider themselves distinct from other sectors of societies” now in their territories. Cobo further stressed that Indigenous people and communities are minorities within contemporary populations that work to preserve their ethnic identities and ancestral territories for future generations. It is important to include displaced people whom prior to colonization identified with specific land areas or regional areas as homelands, as well as Indigenous communities that have for decades been in hiding in areas away from their initial homeland areas. Many descendants of Indigenous people were forced to hide their identities for their own safety due to colonization and genocidal policies focused on physical and cultural erasure. That does not make them non-Indigenous. It makes them survivors of genocide, erasure, and forced acculturation. Many Indigenous people are just coming to terms with the impact of ethnic cleansing and the work to reclaim and revive their identities and cultures. Indigenous is both a legal term, and a personal, group, and pan-group identity. Scholars have argued there are at least four thousand Indigenous groups, but that number is likely very low. Indigeneity is not as simple as an opposition to identity erasure or a push back against colonization. Indigeneity is woven through diverse experiences and histories and is often described as a pan-political identity in a postcolonial time. However, that can be misleading, as the world does not yet exist in a postcolonial state, despite ongoing concerted efforts by Indigenous people and their allies in political and academic spheres to decolonize institutions and communities. Diverse Indigenous communities weave Indigeneity through a multifaceted array of space and time to revive identities and cultural practices and to regain or retain land, human rights, heritage, and political standing.

Biomedical definitions of health have conventionally taken problem-based approaches to health, which may disregard indigenous perspectives of health that take a holistic approach and emphasize the importance of maintaining balance between physical, mental, and spiritual health and relationships maintained with others, the land, and the spiritual realm. Resilience-based approaches to health have been shown to foster strengths in indigenous communities, including the Native Hawaiian community, which leads to more positive health outcomes. The research questions of this paper asked, “how do Native Hawaiians conceptualize health and the concept of resilience specific to health?”. Qualitative methods were employed to explore the concept of resilience from the perspective of 12 Native Hawaiian adults. Community leaders and key stakeholders aided in the purposive recruitment process. The themes of this study include: (1) health maintained through balance, (2) being unhealthy vs. being ill, (3) the concept of colonialism and resulting adversities, and (4) protective and resilience factors that foster health. Cultural values and cultural practices may address concerns related to health disparities that stem from cultural and historical trauma, determinants of health, and environmental changes. Health interventions that are culturally-, family-, spiritually-, and land-based may particularly aid in responsiveness to health programs.

As portable devices become smaller and more convenient, they increasingly require miniaturized batteries that preserve the light weight of the device while delivering sufficient power. However, miniaturization of conventional magnetic devices is precluded by the magnetic material and helical structure of the coil. To solve this problem, we introduce a multilayer ceramic technology that realizes three-dimensional miniature magnetic devices. The miniature components are fabricated by micro-electro-mechanical systems (MEMS) technology. This paper describes an electromagnetic motor and an electromagnetic induction type air turbine generator developed through MEMS and multilayer ceramic technologies. The fabricated motor is 4.2 [mm] in diameter and 6.0 [mm] in height, runs at 1080 rpm, and has a consumption power of 0.11 [W]. The air turbine generator is 10.6 [mm] long, 10.6 [mm] wide, and 3.6 [mm] high. Connected to a 4 [Ω] load resistor, its output power is 195 [μVA] at a rotational speed of 9000 rpm.

<p>This paper examines and shares the promising practices that emerged from an innovative project, entitled “Feasting for Change,” in promoting health and well-being. Taking place on Coast Salish territories, British Columbia, Canada, Feasting for Change aimed to empower Indigenous communities to revitalize traditional knowledge about the healing power of foods. This paper contributes to a growing body of literature that illuminates how solidarities between Indigenous and non-Indigenous communities can be fostered to support meaningful decolonization of mainstream health practices and discourses. In particular, it provides a hopeful model for how community-based projects can take inspiration and continual leadership from Indigenous Peoples. This paper offers experiential and holistic methods that enhance the capacity for intergenerational, land-based, and hands-on learning about the value of traditional food and cultural practices. It also demonstrates how resources (digital stories, plant knowledge cards, celebration cookbooks, and language videos) can be successfully developed with and used by community to ensure the ongoing process of healthful revitalization. </p>
