TL;DR: The most common mechanisms of injury were traffic accidents and falls, and over time, the contribution of traffic accidents to total TBI events may be reducing.
Abstract: This systematic review provides a comprehensive, up-to-date summary of traumatic brain injury (TBI) epidemiology in Europe, describing incidence, mortality, age, and sex distribution, plus severity, mechanism of injury, and time trends. PubMed, CINAHL, EMBASE, and Web of Science were searched in January 2015 for observational, descriptive, English language studies reporting incidence, mortality, or case fatality of TBI in Europe. There were no limitations according to date, age, or TBI severity. Methodological quality was assessed using the Methodological Evaluation of Observational Research checklist. Data were presented narratively. Sixty-six studies were included in the review. Country-level data were provided in 22 studies, regional population or treatment center catchment area data were reported by 44 studies. Crude incidence rates varied widely. For all ages and TBI severities, crude incidence rates ranged from 47.3 per 100,000, to 694 per 100,000 population per year (country-level studies)...

TL;DR: A range of evidence supports a positive terrestrial carbon sink in response to iCO2, albeit with uncertain magnitude and strong suggestion of a role for additional agents of global change.
Abstract: Atmospheric carbon dioxide concentration ([CO2 ]) is increasing, which increases leaf-scale photosynthesis and intrinsic water-use efficiency. These direct responses have the potential to increase plant growth, vegetation biomass, and soil organic matter; transferring carbon from the atmosphere into terrestrial ecosystems (a carbon sink). A substantial global terrestrial carbon sink would slow the rate of [CO2 ] increase and thus climate change. However, ecosystem CO2 responses are complex or confounded by concurrent changes in multiple agents of global change and evidence for a [CO2 ]-driven terrestrial carbon sink can appear contradictory. Here we synthesize theory and broad, multidisciplinary evidence for the effects of increasing [CO2 ] (iCO2 ) on the global terrestrial carbon sink. Evidence suggests a substantial increase in global photosynthesis since pre-industrial times. Established theory, supported by experiments, indicates that iCO2 is likely responsible for about half of the increase. Global carbon budgeting, atmospheric data, and forest inventories indicate a historical carbon sink, and these apparent iCO2 responses are high in comparison to experiments and predictions from theory. Plant mortality and soil carbon iCO2 responses are highly uncertain. In conclusion, a range of evidence supports a positive terrestrial carbon sink in response to iCO2 , albeit with uncertain magnitude and strong suggestion of a role for additional agents of global change.

TL;DR: The Arabic version of the FCV-19S is psychometrically robust and can be used in research assessing the psychological impact of COVID-19 among a Saudi adult population.
Abstract: Fear is a central emotional response to imminent threats such as the coronavirus-19 disease (COVID-19). The Fear of COVID-19 Scale (FCV-19S) assesses the severity of fear towards COVID-19. The present study examined the psychometric properties of the Arabic version of the FCV-19S. Using a forward-backward translation, the FCV-19S was translated into Arabic. An online survey using the Arabic versions of FCV-19S and the Hospital Anxiety and Depression Scale (HADS) was administered. Reliability and concurrent and confirmatory validity were examined. The dataset consisted of 693 Saudi participants. The internal consistency of the Arabic FCV-19S was satisfactory (α = .88), with sound concurrent validity indicated by significant and positive correlations with HADS (r = .66). The unidimensional structure of the FCV-19S was confirmed. The Arabic version of the FCV-19S is psychometrically robust and can be used in research assessing the psychological impact of COVID-19 among a Saudi adult population.

TL;DR: A large and increasing number of people have various neurological disorders in the US, with significant variation in the burden of and trends in neurological disorders across the US states, and the reasons for these geographic variations need to be explored further.
Abstract: IMPORTANCE Accurate and up-to-date estimates on incidence, prevalence, mortality, and
disability-adjusted life-years (burden) of neurological disorders are the backbone of
evidence-based health care planning and resource allocation for these disorders. It appears
that no such estimates have been reported at the state level for the US.
OBJECTIVE To present burden estimates of major neurological disorders in the US states by
age and sex from 1990 to 2017.
DESIGN, SETTING, AND PARTICIPANTS This is a systematic analysis of the Global Burden of
Disease (GBD) 2017 study. Data on incidence, prevalence, mortality, and disability-adjusted
life-years (DALYs) of major neurological disorders were derived from the GBD 2017 study of
the 48 contiguous US states, Alaska, and Hawaii. Fourteen major neurological disorders were
analyzed: stroke, Alzheimer disease and other dementias, Parkinson disease, epilepsy,
multiple sclerosis, motor neuron disease, migraine, tension-type headache, traumatic brain
injury, spinal cord injuries, brain and other nervous system cancers, meningitis, encephalitis,
and tetanus.
EXPOSURES Any of the 14 listed neurological diseases.
MAIN OUTCOME AND MEASURE Absolute numbers in detail by age and sex and
age-standardized rates (with 95% uncertainty intervals) were calculated.
RESULTS The 3 most burdensome neurological disorders in the US in terms of absolute
number of DALYs were stroke (3.58 [95% uncertainty interval [UI], 3.25-3.92] million DALYs),
Alzheimer disease and other dementias (2.55 [95% UI, 2.43-2.68] million DALYs), and
migraine (2.40 [95% UI, 1.53-3.44] million DALYs). The burden of almost all neurological
disorders (in terms of absolute number of incident, prevalent, and fatal cases, as well as
DALYs) increased from 1990 to 2017, largely because of the aging of the population.
Exceptions for this trend included traumatic brain injury incidence (−29.1% [95% UI, −32.4%
to −25.8%]); spinal cord injury prevalence (−38.5% [95% UI, −43.1% to −34.0%]); meningitis
prevalence (−44.8% [95% UI, −47.3% to −42.3%]), deaths (−64.4% [95% UI, −67.7% to
−50.3%]), and DALYs (−66.9% [95% UI, −70.1% to −55.9%]); and encephalitis DALYs
(−25.8% [95% UI, −30.7% to −5.8%]). The different metrics of age-standardized rates varied
between the US states from a 1.2-fold difference for tension-type headache to 7.5-fold for
tetanus; southeastern states and Arkansas had a relatively higher burden for stroke, while
northern states had a relatively higher burden of multiple sclerosis and eastern states had
higher rates of Parkinson disease, idiopathic epilepsy, migraine and tension-type headache,
and meningitis, encephalitis, and tetanus.
CONCLUSIONS AND RELEVANCE There is a large and increasing burden of noncommunicable
neurological disorders in the US, with up to a 5-fold variation in the burden of and trends in
particular neurological disorders across the US states. The information reported in this article
can be used by health care professionals and policy makers at the national and state levels to
advance their health care planning and resource allocation to prevent and reduce the burden
of neurological disorders.

TL;DR: The available evidence supports various pharmacological and non-pharmacological strategies to reduce central sensitisation and to improve patient outcomes in several conditions commonly seen in rheumatology practice and studies suggest the possibility of matching non-Pharmacological approaches, or medications, or both to thecentral sensitisation pain phenotypes.
Abstract: Summary Chronic pain is a leading cause of disability globally and associated with enormous health-care costs. The discrepancy between the extent of tissue damage and the magnitude of pain, disability, and associated symptoms represents a diagnostic challenge for rheumatology specialists. Central sensitisation, defined as an amplification of neural signalling within the CNS that elicits pain hypersensitivity, has been investigated as a reason for this discrepancy. Features of central sensitisation have been documented in various pain conditions common in rheumatology practice, including fibromyalgia, osteoarthritis, rheumatoid arthritis, Ehlers-Danlos syndrome, upper extremity tendinopathies, headache, and spinal pain. Within individual pain conditions, there is substantial variation among patients in terms of presence and magnitude of central sensitisation, stressing the importance of individual assessment. Central sensitisation predicts poor treatment outcomes in multiple patient populations. The available evidence supports various pharmacological and non-pharmacological strategies to reduce central sensitisation and to improve patient outcomes in several conditions commonly seen in rheumatology practice. These data open up new treatment perspectives, with the possibility for precision pain medicine treatment according to pain phenotyping as a logical next step. With this view, studies suggest the possibility of matching non-pharmacological approaches, or medications, or both to the central sensitisation pain phenotypes.

Abstract: The COVID-19 pandemic has had a global impact on the tourism sector. With tourism numbers dramatically reduced, millions of jobs could be lost, and progress made in equality and sustainable economic growth could be rolled back. Widespread reports of dramatic changes to protected and conserved1 area visitation have negative consequences for conservation finances, tourism businesses and the livelihoods of people who supply labour, goods and services to tourists and tourism businesses. This paper aims to share experiences from around the world on the impacts of the COVID-19 pandemic on protected area tourism; and considers how to build resilience within protected area tourism as a regenerative conservation tool.

TL;DR: In this paper, the authors provide an overview of the current situation regarding primary prevention services, estimate the cost of stroke and stroke prevention, and identify deficiencies in existing guidelines and gaps in primary prevention.
Abstract: Stroke is the second leading cause of death and the third leading cause of disability worldwide and its burden is increasing rapidly in low-income and middle-income countries, many of which are unable to face the challenges it imposes. In this Health Policy paper on primary stroke prevention, we provide an overview of the current situation regarding primary prevention services, estimate the cost of stroke and stroke prevention, and identify deficiencies in existing guidelines and gaps in primary prevention. We also offer a set of pragmatic solutions for implementation of primary stroke prevention, with an emphasis on the role of governments and population-wide strategies, including task-shifting and sharing and health system re-engineering. Implementation of primary stroke prevention involves patients, health professionals, funders, policy makers, implementation partners, and the entire population along the life course.

TL;DR: The session rating of perceived exertion (sRPE) method was developed 25 years ago as a modification of the Borg concept of RPE, designed to estimate the intensity of an entire training session.
Abstract: The session rating of perceived exertion (sRPE) method was developed 25 years ago as a modification of the Borg concept of rating of perceived exertion (RPE), designed to estimate the intensity of an entire training session. It appears to be well accepted as a marker of the internal training load. Early studies demonstrated that sRPE correlated well with objective measures of internal training load, such as the percentage of heart rate reserve and blood lactate concentration. It has been shown to be useful in a wide variety of exercise activities ranging from aerobic to resistance to games. It has also been shown to be useful in populations ranging from patients to elite athletes. The sRPE is a reasonable measure of the average RPE acquired across an exercise session. Originally designed to be acquired ~30 minutes after a training bout to prevent the terminal elements of an exercise session from unduly influencing the rating, sRPE has been shown to be temporally robust across periods ranging from 1 minute to 14 days following an exercise session. Within the training impulse concept, sRPE, or other indices derived from sRPE, has been shown to be able to account for both positive and negative training outcomes and has contributed to our understanding of how training is periodized to optimize training outcomes and to understand maladaptations such as overtraining syndrome. The sRPE as a method of monitoring training has the advantage of extreme simplicity. While it is not ideal for the precise recording of the details of the external training load, it has large advantages relative to evaluating the internal training load.

TL;DR: In this paper, the authors discuss four paradoxes of technology central to understanding the nexus between technology consumption and consumer vulnerability and propose a comprehensive research agenda and call for future research that could overcome the limitations of traditional research designs.
Abstract: The COVID-19 pandemic has created unprecedented disruptions in consumers' daily lives. Regulations imposing social distancing, quarantine and full-scale lockdowns have heightened the risks amongst vulnerable consumer groups such as the elderly and socially or financially disadvantaged. However, these restrictions have also caused transitory vulnerability in many people who are not considered vulnerable under normal circumstances. Digital technology has become central to almost every aspect of consumers' lives in response to restriction measures and in coping with pandemic-induced stress and anxiety. Technology-mediated consumption as a coping strategy amidst a crisis is an under-researched topic within the marketing literature. This paper discusses four paradoxes of technology central to understanding the nexus between technology consumption and consumer vulnerability. We propose a comprehensive research agenda and call for future research that could overcome the limitations of traditional research designs. Our work serves as a springboard for future scholarship and opens doors for other researchers to continue exploring this critical research area.

TL;DR: A comprehensive literature survey on the role of inertia for grid flexibility under high penetration of non-synchronous RE sources to the power system and the importance of prior knowledge of the system inertia is addressed.
Abstract: Several studies show that grid-integrated renewable energy (RE) sources have the potential to replace conventional synchronous generators in the network. This means the grid will experience low conventional inertia that is currently provided by synchronous generators. Low, unpredictable and time-changing inertia in the power system, as a result of high penetration of non-synchronous RE sources, can cause rapid frequency oscillations. The rapid and unpredictable frequency oscillations are the major source of stability challenges in the power system. Therefore, this research presents a comprehensive literature survey on the role of inertia for grid flexibility under high penetration of non-synchronous RE sources to the power system. As inertia is becoming a time-changing quantity, inertia estimation techniques have been gaining popularity as solutions to stability challenges faced by the power system. Related to time-changing inertia, the following are discussed in this survey research. First, synthetic inertia provision in the network and the need for inertia estimation are intensively discussed. Second, the importance of prior knowledge of the system inertia, which will help operators to apply suitable control strategies to mitigate stability challenges, is also addressed. Third, the significance of co-existence, coordination and optimization of both conventional synchronous generator's inertia and synthetic inertia, as a key feature towards reliable and flexible grid in low inertia environment, are also emphasized. Finally, technical challenges, key issues, and further research needs are highlighted.

TL;DR: In this article, the authors examined the association between board gender diversity and corporate dividend payout and found that women directors have the greatest impact on dividend payments when there are three or more women on the board.
Abstract: We examine the association between board gender diversity and corporate dividend payout. Our results suggest that although board gender diversity impacts positively on dividend payments, this is only conspicuous in widely held firms. However, when ownership concentration is high, board gender diversity reduces dividend payments. We demonstrate that women directors have the greatest impact on dividend payments when there are three or more women on the board. Our results indicate that the financial crisis period was associated with high dividend payments; however, women directors restrained the payment of dividends during the crisis period. These results suggest that board gender diversity may be an effective CG mechanism for alleviating principal-agent conflicts but not principal-principal agency conflicts. Our results are robust to endogeneity, as well as alternative proxies and estimation techniques.

TL;DR: There are structures still in service with a high seismic vulnerability, which proposes an urgent need for a screening system’s damageability grading system, and the necessity of developing a rapid, reliable, and computationally easy method of seismic vulnerability assessment, more commonly known as RVS.
Abstract: Seismic vulnerability assessment of existing buildings is of great concern around the world. Different countries develop various approaches and methodologies to overcome the disastrous effects of earthquakes on the structural parameters of the building and the human losses. There are structures still in service with a high seismic vulnerability, which proposes an urgent need for a screening system's damageability grading system. Rapid urbanization and the proliferation of slums give rise to improper construction practices that make the building stock's reliability ambiguous, including old structures that were constructed either when the seismic codes were not advanced or not enforced by law. Despite having a good knowledge of structural analysis, it is impractical to conduct detailed nonlinear analysis on each building in the target area to define their seismic vulnerability. This indicates the necessity of developing a rapid, reliable, and computationally easy method of seismic vulnerability assessment, more commonly known as Rapid Visual Screening (RVS). This method begins with a walk-down survey by a trained evaluator , and an initial score is assigned to the structure. Further, the vulnerability parameters are defined (predictor variables), and the damage grades are defined. Various methods are then adopted to develop an optimum correlation between the parameters and damage grades. Soft Computing (SC) techniques including probabilistic approaches , meta-heuristics, and Artificial Intelligence (AI) theories such as artificial neural networks , machine learning, fuzzy logic, etc. due to their capabilities in targeting inherent imprecision of phenomena in real-world are among the most important and widely used approaches in this regard. In this paper, a comprehensive literature review of the most commonly used and newly developed innovative methodologies in RVS using powerful SC techniques has been presented to shed light on key factors, strengths, and applications of each SC technique in advancing the RVS field of study.

TL;DR: In this paper, a difference-in-difference approach is used to make causal inferences on the lockdown effect on happiness, and an OLS estimation investigates the determinants of happiness after lockdown.
Abstract: Amidst the rapid global spread of Covid-19, many governments enforced country-wide lockdowns, with likely severe well-being consequences. In this regard, South Africa is an extreme case suffering from low levels of well-being, but at the same time enforcing very strict lockdown regulations. In this study, we analyse the causal effect of a lockdown and consequently, the determinants of happiness during the aforementioned. A difference-in-difference approach is used to make causal inferences on the lockdown effect on happiness, and an OLS estimation investigates the determinants of happiness after lockdown. The results show that the lockdown had a significant and negative impact on happiness. In analysing the determinants of happiness after lockdown, we found that stay-at-home orders have positively impacted happiness during this period. On the other hand, other lockdown regulations such as a ban on alcohol sales, a fear of becoming unemployed and a greater reliance on social media have negative effects, culminating in a net loss in happiness. Interestingly, Covid-19, proxied by new deaths per day, had an inverted U-shape relationship with happiness. Seemingly people were, at the onset of Covid-19 positive and optimistic about the low fatality rates and the high recovery rates. However, as the pandemic progressed, they became more concerned, and this relationship changed and became negative, with peoples' happiness decreasing as the number of new deaths increased.

TL;DR: A novel method of forecasting the future cases of infection, based on the study of data mined from the internet search terms of people in the affected region, is proposed, where the network parameters of Long Short Term Memory (LSTM) network are optimized using Grey Wolf Optimizer (GWO).
Abstract: The recent outbreak of COVID-19 has brought the entire world to a standstill. The rapid pace at which the virus has spread across the world is unprecedented. The sheer number of infected cases and fatalities in such a short period of time has overwhelmed medical facilities across the globe. The rapid pace of the spread of the novel coronavirus makes it imperative that its' spread be forecasted well in advance in order to plan for eventualities. An accurate early forecasting of the number of cases would certainly assist governments and various other organizations to strategize and prepare for the newly infected cases, well in advance. In this work, a novel method of forecasting the future cases of infection, based on the study of data mined from the internet search terms of people in the affected region, is proposed. The study utilizes relevant Google Trends of specific search terms related to COVID-19 pandemic along with European Centre for Disease prevention and Control (ECDC) data on COVID-19 spread, to forecast the future trends of daily new cases, cumulative cases and deaths for India, USA and UK. For this purpose, a hybrid GWO-LSTM model is developed, where the network parameters of Long Short Term Memory (LSTM) network are optimized using Grey Wolf Optimizer (GWO). The results of the proposed model are compared with the baseline models including Auto Regressive Integrated Moving Average (ARIMA), and it is observed that the proposed model achieves much better results in forecasting the future trends of the spread of infection. Using the proposed hybrid GWO-LSTM model incorporating online big data from Google Trends, a reduction in Mean Absolute Percentage Error (MAPE) values for forecasting results to the extent of about 98% have been observed. Further, reduction in MAPE by 74% for models incorporating Google Trends was observed, thus, confirming the efficacy of utilizing public sentiments in terms of search frequencies of relevant terms online, in forecasting pandemic numbers.

TL;DR: In this article, the authors describe the application of a particular form of technology-enabled participatory action research, called the Our Voice citizen science research model, with youth and present future directions for the advancement of this type of community-engaged citizen science among young people across the socioeconomic spectrum.
Abstract: Growing socioeconomic and structural disparities within and between nations have created unprecedented health inequities that have been felt most keenly among the world’s youth. While policy approaches can help to mitigate such inequities, they are often challenging to enact in under-resourced and marginalized communities. Community-engaged participatory action research provides an alternative or complementary means for addressing the physical and social environmental contexts that can impact health inequities. The purpose of this article is to describe the application of a particular form of technology-enabled participatory action research, called the Our Voice citizen science research model, with youth. An overview of 20 Our Voice studies occurring across five continents indicates that youth and young adults from varied backgrounds and with interests in diverse issues affecting their communities can participate successfully in multiple contributory research processes, including those representing the full scientific endeavor. These activities can, in turn, lead to changes in physical and social environments of relevance to health, wellbeing, and, at times, climate stabilization. The article ends with future directions for the advancement of this type of community-engaged citizen science among young people across the socioeconomic spectrum.

TL;DR: In this paper, the authors explored the spatially varying relationship between destination attributes and COVID-19-disrupted Airbnb performance change across Florida counties and performed two experimental studies to examine whether trip purpose and the level of perceived threat affect Airbnb use intention.
Abstract: The COVID-19 pandemic has disrupted peer-to-peer (P2P) accommodation markets However, how the interplay between tourists and destination attributes has affected P2P accommodation consumption during the pandemic has not been investigated To address this gap, this study first explored the spatially varying relationship between destination attributes and COVID-19-disrupted Airbnb performance change across Florida counties Subsequently, we performed two experimental studies to examine whether trip purpose and the level of perceived threat affect Airbnb use intention The results of the spatial analysis show that, depending on the type of destination attribute, Airbnb listings experienced different revenue losses across urban and rural areas Additionally, results of experimental studies show that business tourists with a low perceived threat of COVID-19 are more willing to consume Airbnb listings than leisure tourists This study contributes to ascertaining the destination and behavioral heterogeneity in pandemic-induced P2P accommodation consumption using spatial analytic and experimental studies

TL;DR: In this paper, the authors present a new framework for describing treeline-forming processes, focusing on hillside-scale patterns, using pattern dimensions with distinct indicative values: 1) the spatial pattern in the x-y plane: a) decline in tree cover, and b) change in the level of clustering.
Abstract: Globally, treeline ecotones vary from abrupt lines to extended zones of increasingly small, stunted and/or dispersed trees. These spatial patterns contain information about the processes that control treeline dynamics. Describing these patterns consistently along ecologically meaningful dimensions is needed for generalizing hypotheses and knowledge about controlling processes and expected treeline shifts globally. However, existing spatial categorizations of treelines are very loosely defined, leading to ambiguities in their use and interpretation. To help better understand treeline‐forming processes, we present a new framework for describing alpine treeline ecotones, focusing on hillside‐scale patterns, using pattern dimensions with distinct indicative values: 1) the spatial pattern in the x‐y plane: a) decline in tree cover, and b) change in the level of clustering. Variation along these dimensions results in more or less ‘discrete' or ‘diffuse' treelines with or without islands. These patterns mainly indicate demographic processes: establishment and mortality. 2) Changes in tree stature: a) decline in tree height, and b) change in tree shape. Variation along these dimensions results in more or less ‘abrupt' or ‘gradual' treelines with or without the formation of environmental krummholz. These patterns mainly indicate growth and dieback processes. Additionally, tree population structure can help distinguish alternative hypotheses about pattern formation, while analysing the functional composition of the ecotonal vegetation is essential to understand community‐level processes, controlled by species‐specific demographic processes. Our graphical representation of this framework can be used to place any treeline pattern in the proposed multi‐dimensional space to guide hypotheses on underlying processes and associated dynamics. To quantify the dimensions and facilitate comparative research, we advocate a joint effort in gathering and analysing spatial patterns from treelines globally. The improved recognition of treeline patterns should allow more effective comparative research and monitoring and advance our understanding of treeline‐forming processes and vegetation dynamics in response to climate warming.

TL;DR: The need to move towards higher frequency for high accuracy in a multi-resident environment and the implications of mmWave exposure on human health and the effect of environmental attenuation are analyzed.
Abstract: Vital signs are inarguably accepted as important key constituents to improve the health condition. Worldwide medical institutions and clinical observations have emphasized the need for continuous monitoring of vital signs such as heart rate (HR) and respiration rate (RR) for better health management. Radars are investigated as one of the potential technologies for non-contact continuous monitoring of vital signs. This paper provides a comprehensive technological review on the current state-of-art of non-contact vital sign (NCVS) measurements using radar. We highlight the need to move towards higher frequency for high accuracy in a multi-resident environment and analyze the implications of mmWave exposure on human health and the effect of environmental attenuation. Significant challenges associated with hardware and signal processing algorithm are discussed in detail. Finally, we conclude the review with future directions and challenges associated with the detection of vital signs in a multi-resident indoor environment.

TL;DR: An updated assessment framework is devised that introduces the option of using a dynamic baseline to assess future impacts of conservation over the short term to avoid misleading results which were generated in a small number of cases, and redefines short term as 10 years to better align with conservation planning.
Abstract: Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a "Green List of Species" (now the IUCN Green Status of Species). A draft Green Status framework for assessing species' progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species' viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics (conservation legacy, conservation dependence, conservation gain, and recovery potential). We tested the framework with 181 species representing diverse taxa, life histories, biomes, and IUCN Red List categories (extinction risk). Based on the observed distribution of species' recovery scores, we propose the following species recovery categories: fully recovered, slightly depleted, moderately depleted, largely depleted, critically depleted, extinct in the wild, and indeterminate. Fifty-nine percent of tested species were considered largely or critically depleted. Although there was a negative relationship between extinction risk and species recovery score, variation was considerable. Some species in lower risk categories were assessed as farther from recovery than those at higher risk. This emphasizes that species recovery is conceptually different from extinction risk and reinforces the utility of the IUCN Green Status of Species to more fully understand species conservation status. Although extinction risk did not predict conservation legacy, conservation dependence, or conservation gain, it was positively correlated with recovery potential. Only 1.7% of tested species were categorized as zero across all 4 of these conservation impact metrics, indicating that conservation has, or will, play a role in improving or maintaining species status for the vast majority of these species. Based on our results, we devised an updated assessment framework that introduces the option of using a dynamic baseline to assess future impacts of conservation over the short term to avoid misleading results which were generated in a small number of cases, and redefines short term as 10 years to better align with conservation planning. These changes are reflected in the IUCN Green Status of Species Standard.
