Drivers of Agricultural Diversity in the Contiguous United States

The spatial heterogeneity of vegetation types on a landscape has been linked to multiple ecosystem functions, including habitat for wildlife and pollinators, water cycling, human aesthetic values, and nutrient cycling. Although agricultural land uses are sometimes combined into a single unit when quantifying landscape heterogeneity, diverse cropping systems are a valuable alternative to near-monocultural croplands and contribute more strongly to ecosystem service provision, including services such as pest regulation and carbon sequestration that are of direct interest for agriculture. The USDA Cropland Data Layer was used to characterize crop diversity across the contiguous US for 2008-2018. Percentage of each crop type, along with non-crop uses such as forest and development, were calculated for each 4km PRISM climate data grid cell. To better understand the drivers of crop diversity, Random Forest modeling was used to assess the importance of climate, soils, and irrigation for patterns of crop effective richness for the contiguous United States, stratified by USDA Land Resource Region. The models explained 57-89% of the variation in maximum crop diversity, with irrigation being by far the most important explanatory variable in regions where it was employed. The drivers of change from 2008 to 2018 were less clear. Random Forest models explained only 20-60% of the change in agricultural diversity over the eleven-year period; both soil and climate properties were important, with no clear dominant drivers. Potential crop effective richness was greater than actual across the entire region studied, but substantial increases would require irrigation. Major changes in agricultural systems and infrastructure may be necessary to increase agricultural diversity at large spatial extents, and declining availability of water for irrigation could threaten the agricultural systems that are now most diverse.

Controls on the Tropical Response to Abrupt Climate Changes

AbstractAbrupt climate change events during glacial times have distinct tropical imprints, despite their cause being at high latitudes. The mechanisms by which high latitudes affect low latitudes are currently unclear. We present climate model simulations of a set of different abrupt events and find changes in tropical rainfall can not be comprehensively explained by either changes in sea ice extent or ocean circulation. Changes in tropical meridional temperature gradients are the clearest way to explain tropical rainfall changes across all events. We find some tropical regions are unlikely to record Heinrich events because the rainfall is moved far enough away from them during stadial periods that they are insensitive to further change. Greenland temperature responds linearly to Atlantic sea ice extent, suggesting that the absence of change in Greenland temperature during Heinrich events implies no sea ice expansion, despite major changes in the climate system elsewhere.

Gender and Age in Funerary Practices in the Ceramic Periods in Central Chile

The Ceramic Periods in central Chile are a scenario of major changes in mobility and subsistence systems, associated with the incorporation of cultigens as the basis of subsistence. In this paper, we present a study of the funerary contexts of the Ceramic Periods in central Chile in order to assess whether in this scenario, generally considered very significant in the low-scale societies studied here, gender categories were constructed or signified, and how this changed over time. The results of the analysis suggest that gender categorization was not always important in this scenario. Among Llolleo groups, the offerings associated with females and children suggest their relation with production spheres; in Bato groups, on the other hand, age categories seem to be more important. In the Late Intermediate Period, it is the collective aspect that appears to be stressed in the funerary contexts.

Exergy as Criteria for Efficient Energy Systems—A Spatially Resolved Comparison of the Current Exergy Consumption, the Current Useful Exergy Demand and Renewable Exergy Potential

The energy transition from fossil-based energy sources to renewable energy sources of an industrialized country is a big challenge and needs major systemic changes to the energy supply. Such changes require a holistic view of the energy system, which includes both renewable potentials and consumption. Thereby exergy, which describes the quality of energy, must also be considered. In this work, the determination and analysis of such a holistic view of a country are presented, using Austria as an example. The methodology enables the calculation of the spatially resolved current exergy consumption, the spatially resolved current useful exergy demand and the spatially resolved technical potential of renewable energy sources (RES). Top-down and bottom-up approaches are combined in order to increase accuracy. We found that, currently, Austria cannot self-supply with exergy using only RES. Therefore, Austria should increase the efficiency of its energy system, since the overall exergy efficiency is only at 34%. The spatially resolved analysis shows that in Austria the exergy potential of RES is rather evenly distributed. In contrast, the exergy consumption is concentrated in urban and industrial areas. Therefore, the future energy infrastructure must compensate for these spatial discrepancies.

What is "shared" in shared decision-making? Philosophical perspectives, epistemic justice, and implications for health professions education.

Drawing from the philosophical work of Hans-Georg Gadamer and the perspectives of theorists Mikhail Bakhtin and Kenneth Burke, the aim of this paper is to critically reflect on the meaning of the word "shared." The authors draw on the concept of epistemic justice, which they argue permeates the clinical encounter, to discuss how various forms of, and claims to, knowledge may influence the attainement of shared decision-making in health care contexts. The specific objectives are twofold: first, the authors draw key concepts from key Gadamerian, Burkean, and Bakhtinian philosophical perspectives to consider shared decision-making in relation to two types of epistemic injustice: testimonial and hermeneutic epistemic injustice. Second, building on philosopher Paulo Freire's critical pedagogy, the authors emphasize that major changes in educational structures and systems are required to promote the critical reflexivity required to address issues of epistemic justice, in the broader pursuit of authentic shared decision-making. They propose three main areas of focus for helath professions education: (a) changes in content (moving from a focus on biomedical knowledge to more content on social sciences) and methods of teaching (more dialogue and the creation of moments of dissonance); (b) a re-examination of teachers' role in promoting epistemic justice; and (c) inclusion of patients as partners. Without major transformation in what, how, and with whom we teach, future clinicians may be unprepared to enact shared decision-making in a manner that does justice to the various ways of knowing.

Study on the Construction of Total Quality Management based on Internet Educational Teaching Research Projects

Abstract: With the development of the Internet era, universities have made major changes in teaching, management, and organizational systems, and have given higher requirements for teaching quality. Therefore, it is necessary to establish a comprehensive quality management system that is compatible with the Internet age. Combined with the developmental background and technical means of the Internet age, we will build a comprehensive management system and mechanism based on network technology, improve the quality management of teaching in colleges with the Internet, establish consciousness of service-oriented management, and promote the teaching and management concepts in colleges. This paper mainly analyzes the constructional problems in total quality management based on Internet educational teaching research projects, and proposes corresponding approaches.

COVID-19 Pandemic: Oral Repercussions and its Possible Impact on Oral Health

Many viral infections cause oral manifestations, including disorders in odontogenesis, resulting in dental malformations. In this review, based on current knowledge, we will discuss the likely dental and oral consequences of COVID-19. In this article, we review currently available data associated with vertical transmission of COVID-19 and odontogenesis, oral manifestations, and the impact of COVID-19 pandemic on a diagnosis of oral diseases. Owing to the severity of the pandemic, the population's anxiety and fear of becoming infected with COVID-19 may underestimate the signs and symptoms of serious illnesses, besides discourage patients from seeking health, medical or dental services to determine the diagnosis of oral lesions. Thus, the COVID-19 pandemic could be an additional and aggravating factor for the delay of serious illness diagnosis, such as oral squamous cell carcinoma resulting in higher morbidity and worse prognosis. Several changes and oral lesions have been described as oral manifestations of COVID-19, such as dysgeusia, oral ulcers, petechiae, reddish macules, desquamative gingivitis, among others. Besides, it can cause major systemic changes and predispose opportunistic infections. As with other viral infections, oral manifestations, including dental anomalies, can occur as a direct result of SARS-CoV-2 infection. However, further studies are needed to guide and clarify possible oral changes.

Closer supervision in Australian general practice training: planning major system change.

Major system change involving closer supervision of trainee GP registrars in Australia is warranted. Change management guidelines recommend involving stakeholders in developing change. The views of those involved in general practice training about current and potential supervisory practice were explored. Semi-structured interviews were conducted with a lead medical educator from nine Australian regions. Focus groups were conducted with GP supervisors and GP registrars. Transcripts from the interviews and focus groups were analysed using conventional content analysis, with themes emerging inductively from the data. The findings were that over 1-3 months, a registrar could progress from their supervisor observing all consultations through to the registrar only calling when they identify the need for help. There is strong support from registrars for this change to closer supervision, but less support from supervisors and educators. Barriers to the proposed change include high clinical demand competing with teaching capacity, inadequate payment for closer supervision and supervisors lacking skills or motivation to have a more active role in registrar supervision. If funding and logistic barriers to change are addressed, a change to a closer level of supervision is possible. A pilot study to further refine the change is indicated.

Physiological and anatomical changes during pregnancy

The body undergoes numerous physiological changes during pregnancy in order to provide an adequate environment for fetal development, meet the increased metabolic demands and prepare for childbirth Pregnancy is a natural but altered physiological state resulting in major changes in cardiovascular system, respiratory system, endocrine system, reproductive system and skeletal and bone changes. The body undergoes a number of physiological changes over the course of pregnancy. For both doctors and patients, the cutaneous findings may be most obvious and sometimes alarming. Obstetricians and dermatologists ought to be able to differentiate between normal changes and unhealthy ones. The pregnant mother undergoes essential physiological changes during pregnancy in order to support and accommodate the developing fetus. These modifications start after conception and affect every organ system in the body. This review underlines the major changes that occur during normal pregnancy.

COVID pandemic and clinical nutrition response in Spain: results of a national survey

Introduction: the SARS-CoV-2 pandemic has forced major organizational and care changes in the health system. However, in Spain, the circumstances suffered by the health professionals who have cared for pandemic patients from a clinical nutrition standpoint has remained unknown up to this moment. Objectives: the management and care changes made in clinical nutrition units in Spain, and their impact on clinical practice are described. Material and methods: a cross-sectional study was carried out using a survey directed at SENPE members (June 2020). Responses sent by health professionals in the field of clinical nutrition who had treated patients with COVID-19 in Spanish hospitals were included in the study. Resultados: a total of 116 survey forms were analyzed, mostly filled out by doctors (57.8 %) working at hospitals with more than 500 beds (56 %); 46 % of survey respondents were on telework. There was a nutritional care plan in 68 % of cases, such plan being present mainly in hospitals with more than 500 beds (p < 0.001). In these hospitals more specific diets for COVID-19 were implemented than in those under 500 beds: 18 (35.3 %) vs 44 (67.7 %), (p < 0.001). The use of recommendations issued by scientific societies was reported in 86 % of cases. Never or almost never could a satisfactory nutritional assessment be performed for 38.8 %. The prescription of nutritional supplements was not less than 50 %. Health workers rated their performance as satisfactory or very satisfactory (51.7 %), and this was not related to hospital size but to having implemented a COVID-19 diet (p < 0.05). Conclusions: clinical nutrition in Spain has responded to the COVID-19 pandemic with organizational and managerial changes and, although care has been clearly affected, some quality standards were ultimately maintained. Larger hospitals have had some advantages in making these adjustments.

Software-supported collaboration in small- and medium-sized enterprises

PurposeThis paper aims to understand the current state and challenges of deploying collaborative applications in small- and medium-sized enterprises (SMEs) in Germany.Design/methodology/approachA survey of 101 SMEs in Germany showed how intensively collaborative applications are used today and the positive and negative effects associated with their use. Analyses proved correlations between the use of collaborative applications, the need for cooperation within SMEs and the effects and benefits of their use.FindingsThe company representatives surveyed reported a positive balance of their pro and con experiences with collaborative applications. The use of collaborative applications closely interacts with work-related demands: the more complex the requirements of joint action, the broader the benefits and challenges are of their use. The data also revealed three gaps between demand of cooperation and use of specific applications, supporting the argument that implementation of collaborative applications is challenging for SMEs. A successful use requires major changes in work systems and culture of the company.Research limitations/implicationsThe data of the survey are not representative of the population of SMEs in Germany.Originality/valueThese empirical findings contribute a unique as well as substantive view of today’s state of digitalisation of project communication and management within SMEs, specifically their deployment of collaborative software.

The role of the political elite in aggravating civil peace in Iraq after 2003

Due to their power and capacity within the political system of the political elites have taken up a privileged position among the other various elites. Yet the first-ever threat to civil peace and coexistence in any society comes from the political system and the prevailing elites. In the post-2003 situation, the major changes in the Iraqi political system have come from the situation in which the one-party system was ended in favor of adopting a democratic system that is based on elections and a multi-party style that is reflected in the new political landscape of the country. Furthermore, the political elites are considered to be the main pillar of the Iraqi political system who have promoted the most important changes that strongly influenced the course of social and political, economic and social life in the country.

Electrification of Industry: Potential, Challenges and Outlook

Industry is one of the most difficult sectors to decarbonize. With the rapidly falling cost of solar PV, wind power, and battery storage, industry electrification coupled with renewable electricity supply has the potential to be a key pathway to achieve industry decarbonization. This paper summarizes the latest research on the possibility of electrification of the industry sector. The transition to industry electrification would entail major changes in the energy system: large scale increases in renewable electricity or nuclear power supplies, the expansion of electricity transmission and distribution networks, completely different end-use technologies for process heating, and new infrastructure for distributing and dispensing hydrogen. Thus, aggressive and sustained supportive policies and much wider research, development, demonstration, and deployment activities are required to meet net zero carbon emissions goals in the industrial sector. Existing economically competitive electrified industrial processes (such as electric arc furnaces for secondary steelmaking from scrap steel), coupled with zero-carbon electricity sources can sharply reduce greenhouse gas emissions (GHG) compared to manufacturing processes that rely on fossil fuels. Fuel switching in industry from fossil fuel–based process heating to electrified heat can offer many product and productivity benefits, but operating costs in general are much higher than fossil fuel-based heating. Either much lower costs of electricity and energy storage are required and/or new, cost-competitive electric-technology applications are needed to enable further electrification of industry. Indirect electrification i.e., hydrogen production via water electrolysis is another complimentary technology reliant on electricity. Hydrogen can be used as an energy carrier, industrial feedstock for products and fuels, or for long-duration energy storage, and thus can also play a key role in industry decarbonization when the hydrogen is produced from zero-carbon electricity and/or with carbon capture and storage. As with direct electrification, cost is the key barrier for the deployment of hydrogen resources.

Stories from the end of the world: in search of plots for a failing system

PurposeThe purpose of this paper is to consider three types of stories: media, personal accounts and fiction, and look for plots depicting situations of fundamental shift in the framing and basic definitions of reality. The authors examine them from the point of view of their usefulness for developing creative responses to systemic change.Design/methodology/approachThe authors conducted a narrative study in three stages, aimed at identifying strong plots pertaining to systemic change. The analyzed material came from three different sources of narratives (fiction, media and creative stories) and was approached by the use of two different narrative methods: symbolic interpretation and narrative collage.FindingsCurrently many voices are being raised that the authors are living in times of interregnum, a period in between working systems. There is also a mounting critique of the business school as an institution perpetuating dysfunctional ideologies, rather than enhancing critical and creative thinking. The authors propose that the humanities, and, in particular, learning from fiction (and science fiction) can offer a language to talk about major (systemic) change help and support learning about alternative organizational realities.Research limitations/implicationsThe study pertains to discourse and narratives, not to material aspects of culture construction.Practical implicationsToday, there is a mounting critique of business schools and their role in society. Following Martin Parker’s call to transform them into schools of organizing, helping to develop and discuss different alternatives instead of reproducing the dominant model, the authors suggest that education should be based, to much larger extent than until now, on the humanities. The authors propose educational programmes including the study of fiction and film.Social implicationsThe authors propose that the humanities (and the study of fiction) can equip society with a suitable language to discuss and problematize systemic change.Originality/valueThis paper adds to narrative social studies through providing an analysis of strong plots showing ways of coping with systemic collapse, and through an examination of these plots’ significance for organizational education, learning, and planning. The authors present an argument for the broader use of fiction as a sensemaking, teaching, and learning tool for managing organizations in volatile environments.

Poor Involvement of General Practitioners in Decisions of Withholding or Withdrawing Life-Sustaining Treatment in Emergency Departments.

Decisions of withholding or withdrawing life-sustaining treatment are frequent in emergency departments (ED) and patients are often unable to communicate their wishes concerning end of life desires. To evaluate the participation of general practitioners (GPs) during the decision-making process of withholding or withdrawing life-sustaining treatments in ED. Prospective observational multicenter study. We included patients for whom a decision of withdrawing or withholding life-sustaining treatments was made in ED. For each patient, we enrolled one general practitioner. GPs were interviewed about their perception of end of life patient's management and the communication with ED and families. There were 109 potential patient participants. We obtained answers from 54 (49.5%) of the patient's associated GPs. Only 4 (7.4%) GPs were involved during the decision-making process of withholding or withdrawing life-sustaining treatments. Among GPs, 29 (53.7%) were contacted by family after the decision, most often to talk about their difficult experience with the decision. A majority (94%) believed their involvements in these decisions were important and 68% wished to "always" participate in end of life decisions despite the fact that they usually don't participate in these decisions. Finally, 66% of GPs believed that management of end of life in the emergency department was a failure and should be anticipated. GPs would like to be more involved and barriers to GP involvement need to be overcome. We do not have any outcome data to suggest that routine involvement of GPs in all end of life patients improves their outcomes. Moreover, it requires major system and process-based changes to involve all primary care physicians in ED decision-making. NCT02844972.

Globalization and the rise of integrated world society: deterritorialization, structural power, and the endogenization of international society

AbstractThere is a widespread feeling that globalization represents a major system change that has or should have brought world society to the forefront of international relations theory. Nonetheless, world society remains an amorphous and undertheorized concept, and its potential role in shaping the structure of the international society of states has scarcely been raised. We build on Buzan's (2018, 2) master concept of ‘integrated’ world society (‘a label to describe the merger of world and interstate society’) to locate the integration of world society in the globalization of social networks. Following the advice of Buzan (2001) and Williams (2014), we use conceptual frameworks from international political economy to systematically explore the structure of integrated world society along six dimensions derived from Mann (1986) and Strange (1988): military/security, political, economic/production, credit, knowledge, and ideological. Our empirical survey suggests that, on each of these dimensions, power has centralized as it has globalized, generating steep global hierarchies in world society that are similar to those that characterize national societies. The centrality of the United States in the networks of world society makes it in effect the ‘central state’ of a new kind of international society that is endogenized within integrated world society.

Energy resilience through self-organization during widespread power outages

ABSTRACT Resilience of power systems is highly impacted by factors such as increasing severity and frequency of weather events, but also smart grid advances that introduce major operational changes in power systems. Rapidly adapting to these changing circumstances and harnessing the potential of technological advances is the key to ensuring that power systems stay operational during disturbances, thereby improving resilience. This paper addresses this challenge by presenting an approach for improving resilience through local energy resource sharing across multiple distribution systems. The approach brings together the physical and the ICT layer of power systems through a self-organization approach that automatically alters the physical grid topology and forms local energy groups in order to mitigate the effects of widespread outages. Thereby, supply and demand are locally matched, and demand met is maximized during an outage. The results demonstrate that using the proposed approach, operational resilience of impacted distribution systems is improved.

Seismicity and outgassing dynamics of Nyiragongo volcano

Active lava lakes at volcanoes can be regarded as open windows to their magmatic systems. The dynamics of such lakes may therefore provide decisive insights into deeper magmatic processes, potentially leading to fundamental theoretical implications and volcano monitoring improvements. Among the rare volcanoes on Earth hosting a persistent lava lake, Nyiragongo in D.R. Congo directly threatens a massive population of roughly 1 million inhabitants. Here we analyze close-range (i.e., summit) and distant (around 17 km) seismic measurements acquired at this African volcano between 2011 and 2018 in order to better understand the seismic signature of the lava lake activity and how it relates to the deeper volcanic processes. Both summit and distant seismic records contain a similar continuous tremor pattern attributable to the lava lake activity. Combining this information with time-lapse camera images and lava lake level measurements confirms the mechanism of gas pistoning at Nyiragongo, which is characterized by short-duration (a few minutes long) and meter-scale level variations during the period of observation. We also characterize the dominant periodicity of this shallow tremor signature of about a few tens of minutes. Because this marked periodic pattern varies during a significant one-month fluctuation of SO2 emissions (estimated from space), we suggest that this particular seismic periodicity corresponds to the convective lake movement driven by the persistent degassing typical of active open-vent volcanoes. Finally, new seismic evidence reveals the effect of deep magmatic intrusion and consequent major pressure changes in the plumbing system, resulting in sudden and large drops of the lava lake level associated with strong degassing. Such transient episodes have similar characteristics to total lava lake drainage associated with flank eruptions already observed at this volcano in 1977 and 2002, or at Kīlauea volcano in 2018.

A Boundary Plane Approach to Map Hotspots for Achievable Soil Carbon Sequestration and Soil Fertility Improvement

Soil organic carbon (SOC) sequestration is important in the global carbon cycle and an integral part of many initiatives and policies to mitigate climate change. For efficient targeting of measures leading to SOC sequestration, it is necessary to know the actual SOC content (%) and a realistic target SOC content (in contrast to the saturation content, which may not be easily achievable) under local biophysical and socioeconomic conditions. We developed a new method for the practical assessment of achievable SOC sequestration concerning soil texture based on a non-linear boundary plane approach, also applicable for mapping of SOC sequestration hotspots. The method was tested at two spatial scales (a 125 km2 catchment and a 4 km2 sub-area of that catchment) in a region in Western Kenya characterized by smallholder farming. Moreover, we assessed the associated benefits of increasing the SOC content from a crop production perspective and found significant correlations between SOC and other soil properties (pH, cation exchange capacity, and various plant-available macro- and micronutrients). This indicates a possible improvement in soil fertility when the SOC content is raised to the modeled target levels, which should be attainable without major changes in land use or agricultural systems.

The evolution of income-related inequalities in healthcare utilisation in Indonesia, 1993-2014.

ObjectiveWhile the major policy changes in the Indonesian healthcare system over the last 25 years have been well documented, less is known about the accompanying changes in inequalities in healthcare utilisation during this period. Our study aimed to describe the trends in income-related inequalities in healthcare utilisation in Indonesia during the period 1993–2014.MethodsA repeated cross-sectional study was conducted using data from the Indonesian Family Life Surveys from 1993, 2000, 2007, and 2014. We measured outpatient and inpatient healthcare utilisation in public and private provider as well as the overall utilisation. Standardised prevalence rate and relative index of inequality (RII) were used to measure the extent of inequalities in healthcare utilisation by income level (income-related inequalities).ResultsRelatively large income-related inequalities were observed in the utilisation of private outpatient care and public and private inpatient care in 1993. Income-related inequalities in public and private outpatient care utilisation decreased between 1993 and 2007 but increased in 2014. Income-related inequalities in public and private inpatient care utilisation continued to decrease between 1993 and 2014. The largest decrease was observed in private inpatient care utilisation.ConclusionIncome-related inequalities in all types of healthcare utilisation decreased until 2007. This trend continued until 2014 only for public and private inpatient care utilisation. This phenomenon may be explained by the changes to the healthcare system (e.g. expansion of the government health insurance programme and health sector decentralisation), which coincided with the changes in inequalities in healthcare utilisation in Indonesia.
