The Impact

Government agencies in the United States adopted a prescribed burning policy based in part on paleo-environmental evidence of pre-Columbian Native American burning regimes. However, biomass collection by Native Americans in the pre-Columbian era left little direct or indirect evidence of its magnitude or influence on fire regimes. In many developing countries, local peoples harvest biomass for shelter, tool production, cooking, and heating, and often manage forests communally. The objective was to use modern proxy biomass collection estimates analogous to pre-Columbian era practices in the western US to estimate the potential impacts of regionwide firewood collection on fuel loads in the Sierra Nevada range of California. A minimum of 59% of the forested area of the Sierra Nevada range could have been completely stripped of 100 hr (2.54-7.62 cm diameter) surface fuel accumulation each year in the pre-Columbian era, but upper estimates suggest Native American fuelwood requirements may have exceeded the amount of 100 hr surface fuels accumulated over the entire range each year. The collection and removal of the fuels from the surface fuel loads may have contributed to reduced fire severities over that era. Dead wood collection in Nepal and India was found to reduce the threat of forest fires. Including the effects of cultural practices on fuel loads may improve reconstructions of past fuel and fire regimes, and may benefit modern management strategies.

The Impact

Abstract Racial and ethnic disparities are endemic to the United States and are only beginning to attract the attention of researchers. With an increasingly diverse population, focused and tailored medicine to provide more equitable care is needed. For surgical trauma populations, this topic is a small but expanding field and still rarely mentioned in burn medicine. Disparities in prevention, treatment, and recovery outcomes between different racial and ethnic minorities who are burned are rarely discussed. The purpose of this study is to determine the current status of identified disparities of care in the burn population literature and areas of future research. A systematic review was conducted of literature utilizing PubMed for articles published between 2000-2020. Searches were used to identify articles that crossed the burn term (burn patient OR burn recovery OR burn survivor OR burn care) and a race/ethnicity and insurance status-related term (race/ethnicity OR African-American OR Black OR Asian OR Hispanic OR Latino OR Native American OR Indigenous OR Mixed race OR 2 or more races OR socioeconomic status OR insurance status). Inclusion criteria were English studies in the US that discussed disparities in burn injury outcomes or risk factors associated with race/ethnicity. 1,169 papers were populated, 55 were reviewed, and 36 articles met inclusion criteria. Most studies showed minorities had poorer inpatient and outpatient outcomes. While this is a concerning trend, there is a paucity of literature in this field and more research is needed to create culturally-tailored medical care and address the needs of disadvantaged burn survivors.

In Fire

Structural heterogeneity in forests of the Sierra Nevada was historically produced through variation in fire regimes and local environmental factors. The amount of heterogeneity that prescription burning can achieve might now be more limited owing to high fuel loads and increased fuel continuity. Topography, woody fuel loading, and vegetative composition were quantified in plots within replicated early and late season burn units. Two indices of fire severity were evaluated in the same plots after the burns. Scorch height ranged from 2.8 to 25.4 m in early season plots and 3.1 to 38.5 m in late season plots, whereas percentage of ground surface burned ranged from 24 to 96% in early season plots and from 47 to 100% in late season plots. Scorch height was greatest in areas with steeper slopes, higher basal area of live trees, high percentage of basal area composed of pine, and more small woody fuel. Percentage of area burned was greatest in areas with less bare ground and rock cover (more fuel continuity), steeper slopes, and units burned in the fall (lower fuel moisture). Thus topographic and biotic factors still contribute to the abundant heterogeneity in fire severity with prescribed burning, even under the current high fuel loading conditions. Burning areas with high fuel loads in early season when fuels are moister may lead to patterns of heterogeneity in fire effects that more closely approximate the expected patchiness of historical fires.

The Village

The abandonment of the economic activities of agriculture, livestock, and forestry since the second half of the 20th century, in conjunction with the exodus of inhabitants from rural areas, has resulted in an increase in the forest mass as well as an expansion of forest areas. This, in turn, has led to a greater risk of forest fires and an increase in the intensity and severity of these fires. Moreover, these forest masses represent a fire hazard to adjacent urban areas, which is a problem illustrated here by the village of Capafonts, whose former agricultural terraces have been invaded by shrubs, and which in the event of fire runs the risk of aiding the propagation of the flames from the forest to the village’s homes. One of the tools available to reduce the amount of fuel in zones adjoining inhabited areas is prescribed burns. The local authorities have also promoted measures to convert these terraces into pasture; in this way, the grazing of livestock (in this particular instance, goats) aims to keep fuel levels low and thus reduce the risk of fire. The use of prescribed fires is controversial, as they are believed to be highly aggressive for the soil, and little is known about their long-term effects. The alternation of the two strategies is more acceptable—that is, the use of prescribed burning followed by the grazing of livestock. Yet, similarly little is known about the effects of this management sequence on the soil. As such, this study seeks to examine the impact of the management of the abandoned terraces of Capafonts by means of two prescribed fires (2000 and 2002), which were designed specifically to prevent forest fires from reaching the village. Following these two prescribed burns, a herd of goats began to graze these terraces in 2005. Here, we report the results of soil analyses conducted during this period of years up to and including 2017. A plot comprising 30 sampling points was established on one of the terraces and used to monitor its main soil quality properties. The data were subject to statistical tests to determine whether the recorded changes were significant. The results show modifications to the concentration of soil elements, and since the first prescribed burn, these changes have all been statistically significant. We compare our results with those reported in other studies that evaluate optimum soil concentrations for the adequate growth of grazing to feed goats, and conclude that the soil conditions on the terrace after 17 years are optimum for livestock use.

The Impact

The amount, frequency, and duration of precipitation have important impact on the occurrence and severity of forest fires. To fully understand the effects of precipitation regimes on forest fires, a drought index was developed with number of consecutive dry days (daily precipitation less than 2 mm) and total precipitation, and the relationships of drought and precipitation with fire activities were investigated over two periods (i.e., 1982–1988 and 1989–2008) in five ecoregions of Yunnan Province. The results showed that precipitation regime had a significant relationship with fire activities during the two periods. However, the influence of the drought on fire activities varied by ecoregions, with more impacts in drier ecoregions IV-V and less impacts in the more humid ecoregions I–III. The drought was more closely related to fire activities than precipitation during the two study periods, especially in the drier ecoregions, indicating that the frequency and the duration of precipitation had significant influences on forest fires in the drier areas. Drought appears to offer a better explanation than total precipitation on temporal changes in fire regimes across the five ecoregions in Yunnan. Our findings have significant implications for forecasting the local fire dangers under the future climate change.

Abstract. Fire is a major driver of soil organic matter (SOM) dynamics, and contemporary global climate change is changing global fire regimes. We investigated thermal alteration of SOM properties by exposing five different topsoils (0 to 5 cm depth) from the western Sierra Nevada Climosequence to a range of temperatures that are expected during prescribed and wild fires (150, 250, 350, 450, 550 and 650 °C), and determined temperature thresholds for major shifts in SOM properties. With increase in temperature, we found that the concentrations of C and N decreased in a similar pattern among all five soils that varied considerably in their original SOM concentrations and mineralogies. Soils were separated into discrete size classes by dry sieving. The C and N concentrations in the larger aggregate size fractions (2–0.25 mm) decreased with increase in temperature that at 450 °C temperature, the remaining C and N were almost entirely associated with the smaller aggregate size fractions (

Opening with the life and art of Dakota artist Oscar Howe, the chapter discusses the “Indianness” of Native art and the frustrations experienced by Native artists over the years surrounding their creative expressions. The chapter is arranged chronologically, opening in the late nineteenth century and highlighting sample exhibitions, artworks, and artists from the United States in order to illustrate broad conceptual issues. These include Indian authenticity and identity, differences between fine art and “crafts,” traditional versus contemporary art forms, the role of the arts in economic development, and the impact of federal power on the arts. The chapter draws examples from painting, sculpture, photography, video, and performance art. It concludes with a proposal for understanding Native art inspired by the words of Santa Clara artist Rose Simpson.

The Impact

Since the early 1980s, the Hopi filmmaker and photographer Victor Masayesva Jr. has played an influential role in Native American multimedia production in the United States. This article examines Masayesva's filmPaatuwaqatsi: Water, Land and Life(2007), which documents a 1,650-mile run made by Hopis from their home villages in Northern Arizona to Mexico City in early 2006. The run marked the closure of the Mohave Generating Station in southern Nevada and the Black Mesa coal mine which fuelled the power plant. It also celebrated the shutting down of the controversial coal slurry pipeline between the plant and mine that required for its operation the pumping of 1.2 billion gallons of pristine water annually from the Navajo Aquifer, which lies under the homelands of the Hopi and Navajo nations. The article explains how Hopis' affective relationship with place is put into action through the acts of running, prayer and personal sacrifice. It reviews Masayesva’s filmmaking career to date and considers his core idea of the indigenous aesthetic, a set of principles that has guided the practical decisions and artistic choices he has made in the course of over thirty years' working as an independent media producer. After a close analysis of selected scenes inPaatuwaqatsi, the article concludes by noting, first, how the film negotiates internal divisions within Hopi society over development and environmental issues and, second, how it engages the impact of continuing drought and ongoing climate change on the American Southwest.

Importance: Some studies suggest that social media use is associated with risk for depression, particularly among children and young adults. Objective: To characterize the association between self-reported use of individual social media platforms, and worsening of depressive symptoms, among adults. Design: We included data from 13 waves of a non-probability internet survey conducted between May 2020 and May 2021 among individuals age 18 and older in the United States. We applied logistic regression with 5 or more point increase in PHQ-9 as outcome, and sociodemographic features, baseline PHQ-9, and use of each social media platform as independent variables, without reweighting. Participants: Survey respondents 18 and older. Main Outcome and Measure: PHQ-9 worsening by 5 points or more. Results: A total of 5395/8045 (67.1%) individuals with a PHQ-9<5 on initial survey completed a second PHQ-9. These respondents had mean age 55.82 years (SD 15.17); 3546 (65.7%) reported female gender, the remainder male; 329 (6.1%) were Asian, 570 (10.6%) Black, 256 (4.7%) Hispanic, 4118 (76.3%) White, and 122 (2.3%) Native American or Alaska Native, Pacific Islander or Native Hawaiian, or Other. Among them, 482 (8.9%) reported 5 point or greater worsening at second survey. In fully-adjusted models for increase in symptoms, largest odds ratio associated with social media use was observed for Snapchat (aOR 1.53, 95% CI 1.19-1.96), Facebook (aOR 1.42, 1.10-1.81), and TikTok (aOR 1.39, 95% CI 1.03-1.87). Conclusions and Relevance: Among survey respondents who did not report depressive symptoms initially, social media use was associated with greater likelihood of subsequent increase in depressive symptoms after adjustment for sociodemographic features and news sources. These data cannot elucidate the nature of this relationship, but suggest the need for further study to understand the impact of social media use.

The Impact

The attention given to indigenous rights has increased since the approval of the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) in 2007. Although it is a soft law declaration and technically not binding, it serves as the cornerstone of much of the contemporary research on indigenous rights. Four states that initially voted in opposition to the UNDRIP—Australia, Canada, New Zealand, and the United States—have now endorsed it. Despite the attention it garners, the UNDRIP is not the only international instrument that has been utilized to establish and protect indigenous rights and interests. The regional inter-American human rights system has also been key in the development and protection of indigenous rights. Another important facet of the UNDRIP is that it took twenty-two years of drafting effort before it was approved by the United Nations General Assembly. During those twenty-two years, many discussions, debates, and analyses were undertaken over the meaning of rights and principles included in the drafts of the declaration. Research and scholarship from the era before passage of the declaration is helpful in understanding the content of the document. But the approval of the declaration did not end the controversies over indigenous rights. Debate and examination of the evolving body of indigenous rights continues during the period after passage of the declaration. As well, indigenous rights are not simply “human rights”; rather, they are a complex set of rights that can impact a broad swath of other legal doctrines. Intersections of indigenous rights with laws regarding economic development, the environment, and land claims can give rise to new interpretations and understandings of the impact of indigenous rights. While the four “no states” might be what most readily comes to mind when thinking about where many indigenous peoples live, indigenous peoples are, in fact, scattered throughout the world, including Europe. Research on indigenous rights is not carried out only from a legal perspective. Indigenous rights cover many different kinds of rights. Some have an emphasis in international law doctrines, such as the right to self-determination and issues about indigenous and tribal sovereignty. Other rights emphasize the importance of culture and heritage, and it can be useful to consider research in other disciplines, including history, political science, and anthropology. This article includes research and resources in related disciplines as well as legal research and law-based resources. (A note about language: American references to indigenous peoples are inclusive of the words “American Indian” or “Indian.” “Indian” is a legal term of art used in federal and state statutes. Indigenous peoples in the United States refer to themselves as “Indians” rather than Native Americans. For these reasons, where appropriate, the article makes use of the terms American Indian and Indian in preference to Native American. This usage may be confusing to non-American readers and so a clarification is offered).
