Abstract:
In 1922, there were thirty-five state health resorts in the Soviet Union. This article introduces the historic role of health resorts as sites of nature conservation in the Soviet Union, comparable to national parks and nature reserves (zapovedniki), and highlights the role of physicians and medical ideas in the formulation and promotion of conservation policies in the Soviet Union. It analyzes conservation laws and regulations that covered health resorts, prohibiting a range of activities throughout their territories to protect natural healing resources such as mineral waters, muds, and beaches. In the 1930s, Soviet health resorts became influential centers of conservation when the science of ecology lost state support and ecological study centers in the nature reserves were dismantled. The idea that the natural environment should be protected to serve human health gained influence with official patrons in the Soviet state because physicians explicitly aligned the health resorts with the anthropocentric ideology of the state and its goal of industrialization, opening up health resort medicine to the industrial workforce. Health and nature's curative ideas also formed the foundation for nature protection during Stalinism. State patronage of health resort conservation increased in the Stalinist period, culminating in 1940, when the reach of conservation was extended to local health resorts. The article concludes with an examination of conservation work in the Sochi health resort.

Abstract:
The increasing cultural and ethnic diversity in the United States should challenge environmental interpreters to offer programs that attract a variety of audiences. This study investigated minority involvement at Florida's nature centers through a census of 77 nature center directors throughout Florida as well as a survey of 21 minority staff working at these educational facilities. School programs at the nature centers are the primary method for reaching minorities; few programs involve minority adults from the community. The focus of the one-day visits for students is primarily nature awareness, with little emphasis on influencing knowledge or attitudes about local issues, human-environment relationships, or actions to reduce environmental problems. The results indicate the need for nature centers to expand their programs to offer long-term, community-based environmental interpretation for a diverse public.

Abstract:
With the continued rise in screen media use and growing disconnect between youth and nature, the importance of community nature centers in providing natural experiences is increasingly recognized. Even so, many nature centers struggle to maintain public support and funds necessary for continued operations. One way for nature centers to engender public support and further their fundraising potential is through interpretive special events. This study seeks to understand whether (and how) interpretive outcomes of an interpretive special event relate to visitors’ intentions to return to a nature center in the future. The relationship between place attachment and intentions to return was also tested. Results show that affective interpretive outcomes, more than the program-specific outcomes or place attachment, had the strongest effects on intentions to return to the center. This finding was particularly true among new visitors to the nature center. Based on our findings, in addition to providing interpretive messages focused on specific resources, interpretive managers who are interested in increasing repeat visitation to their nature centers should consider placing an even higher priority on programs that create enjoyable and meaningful experiences for visitors.

Abstract:
This dissertation examines three relationships between nature centers and their local communities. First, what are the values provided by local centers as perceived by community members? Second, what factors lead community members to support local centers? And third, what are the constraints to visiting local centers as perceived by community members? We surveyed random samples of community members living around 16 diverse nature centers across the United States and conducted quantitative and qualitative analyses to address these questions. Chapter one introduces the study and provides a literature review of theories and empirical research related to the research questions. Chapter two reports the results of an exploratory factor analysis on the level of importance communities assign to fourteen nature center services. The factor analysis revealed four underlying values: environmental connection, leisure provision, civic engagement, and community resilience. Chapter three tests sixteen hypothesized predictors of community support for nature centers. All these variables were significant, suggesting people volunteer at, donate to, or respond to threats at nature centers for a range of reasons. These include those related to supporting nature center missions (e.g. environmental connection significance and commitment to nature) but also other reasons such as friends' and family's perceptions of nature centers and assessments of the center staff members. Chapter four explores constraints that emerge during different stages of the decision-making process people go through when considering whether or not to visit a local nature center. The greatest constraints emerge in early stages (e.g. center awareness) and late stages (e.g. limited finances, transportation, and time) of decision-making. Chapter five discusses the study's implications to theory, including ecosystem service and educational leisure setting valuation, environmentally significant and charitable support behavior, and leisure constraints, as well as nature center practice. Centers that consider these implications might better serve their local communities and achieve their missions.

Abstract:
Abstract The philosophy of hope centers on two interlocking sets of questions. The first concerns the nature of hope. Specific questions here include how to analyze hope, how hope motivates us, and whether there is only one type of hope. The second set concerns the value of hope. Key questions here include whether and when it is good to hope and whether there is a virtue of hope. Philosophers of hope tend to proceed from the first set of questions to the second. This is a natural approach, for one might expect that you must develop a basic understanding of what hope is before you can determine its value. The structure of this chapter thus follows this approach. But readers should not be misled: there is in fact a good deal of feedback between the two sets of questions. A theory of hope is more plausible to the extent that it fits well with plausible ideas about the value of hope. So the movement from hope’s nature to its value is one of emphasis rather than a strict, step-wise process.

Abstract:
Point defects are detrimental to the most applications which make use of the otherwise excellent optical and dielectric properties of vitreous SiO2. One notable exception to this rule is the writing of photoinduced gratings in SiO2:GeO2 glass fibers. There is ample evidence that the photosensitivity is connected to the presence of point defects in the glass, particularly, to the presence of the so called "oxygen deficiency centers" (ODC’s). While significant advances in optimizing the photoinduced grating writing have been made in recent years, the basic understanding of the underlying microscopic defect processes is still insufficient. The nature of a number of defect-related optical bands is still a matter of discussions. Most unsatisfactorily, the structure of the "key defect" to the fiber writing, the ODC, remains controversial.

Abstract:
Although in-fiber photoinduced structures are widely used in practical applications [1] the nature and the microscopic mechanisms of glass photosensitivity is still unclear. To explain the phenomena observed in fibers under UV-irradiation, several models have been suggested: color center transformation [2], initial stress relief [3], UV-induced glass densification [4]. However these models are not in complete agreement with the experiments. It is well known that germanium oxygen deficient centers (GODCs) play an important role, at least at the initial stage of photoinduced glass transformation. As a rule, the intense GODC absorption band centered at 242 nm is used to write refractive index gratings in germanosilicate fibers.

Abstract:
Absorbing defects are suspected to play a part in laser damage of thin films especially in the UV spectrum1,2. To improve the coating technology, it seems to be very useful to get more information on the localized defects and their relation to damage threshold: the size and the nature of these defects are important questions. Simultaneous mapping of absorption and scattering together and their correlation give specific information about the nature of defects3. Furthermore during their life, UV optical components have to withstand millions of high intensity pulses and can be damaged by long term subthreshold irradiation. Localized losses can play an important part in these phenomena. The present work tries to elucidate the role of absorbing and/or scattering defects in titania and silica films deposited by DIBS on fused silica substrates and irradiated with increasing numbers of shot at subthreshold fluences.

Abstract:
The growing demand for data center facilities has made intelligently managed data center operations necessary. For temperature measurement and thermal management, a common practice is to install a limited number of temperature sensors evenly distributed throughout the room. However, data center operators rarely fully equip facilities with temperature sensors due to their cost, complexity, and maintenance requirements, creating vacancies in the data center temperature and cooling picture. The local nature of sensor data can also be misinterpreted and misused. Without novel methods to interpret and visualize temperatures obtained by prediction or measurement, data center operators cannot easily identify urgent local cooling issues or quickly examine the temperature at other location. This paper presents methods to predict a full three-dimensional temperature field in data centers from a limited number of measurement points. Several different statistical interpolating schemes are discussed. We also validate the interpolated temperature fields against benchmark data from Computation Fluid Dynamics (CFD) and show good agreement.

Abstract:
The subject of this paper is to present the potential risks of current investment in the winter centers of Montenegro, as well as recommendations for the best possible development of tourism in the north of Montenegro. We also want to point out the importance of networking the coastal and northern parts of the country in active tourism throughout the year because the line between those two parts of the country is connected by incredible natural beauty. Global warming has shown that even in larger ski centers in Europe there is a very high risk of investing in ski sport because the period of use of the ski resort in the winter months is getting shorter due to the lack of snow and that it is better to invest in sustainable tourism and animate tourists with the extraordinary natural resources that Montenegro possesses through rural and active tourism, as the best form of a longer stay for tourists in the north of Montenegro and Montenegro in global. This type of tourism is very attractive now, especially after the COVID pandemic when tourists are increasingly opting for individual trips in nature.

Abstract:
The objective of this work is to introduce the application of an artificial neural network (ANN) to assist in the evaporative cooling in data centers. To achieve this task, we employ the neural network algorithms to predict weather conditions outside the data center for direct evaporative cooling (DEC) operations. The predictive analysis helps optimize the cooling control strategy for maximizing the usage of evaporative cooling thereby improving the efficiency of the overall data center cooling system. A typical artificial neural network architecture is dynamic in nature and can perform adaptive learning in minimal computation time. A neural network model of a data center was created using operational historical data collected from a data center cooling control system. The neural network model allows the control of the modular data center (MDC) cooling at optimum configuration in two ways. First way is that the network model minimizes time delay for switching the cooling from one mode to the other. Second way, it improves the reaction behavior of the cooling equipment if an unexpected ambient condition change should come. The data center in consideration is a test bed modular data center that comprises of information Technology (IT) racks, Direct Evaporative cooling (DEC) and Indirect Evaporative Cooling (IEC) modules; the DEC/IEC are used together or in alternative mode to cool the data center room. The facility essentially utilizes outside ambient temperature and humidity conditions that are further conditioned by the DEC and IEC to cool the electronics, a concept know as air-side economization. Various parameters are related to the cooling system operation such as outside air temperature, IT heat load, cold aisle temperature, cold aisle humidity etc. are considered. Some of these parameters are fed into the artificial neural network as inputs and some are set as targets to train the neural network system. After the training the process is completed, certain bucket of data is tested and further used to validate the outputs for various other weather conditions. To make sure the analysis represents real world scenario, the operational data used are from real time data logged on the MDC cooling control unit. Overall, the neural network model is trained and is used to successfully predict the weather conditions and cooling control parameters. The prediction models have been demonstrated for the outputs that are static in nature (Levenberg Marquardt method) as well as the outputs that are dynamic in nature i.e., step-ahead & multistep ahead techniques.

We discuss the nature of the excited states of the NIR laser center in Cr:YAG. Recent results show that this particular center behaves in a similar manner to that of a Cr:alexandrite laser, inasmuch as the first excited state can be considered to be a "storage level" during room temperature laser operation. This follows from NIR laser excitation studies that show the observed low temperature sharp lines at 1277 and 1280 nm are true zero-phonon lines. The first excited state is found to be a doublet, with a splitting of 30 cm-1. These new measurements also lead to a new estimation of the absorption cross-section at 1.064 μm (2 × 10-17 cm2). This relatively high cross-section may affect the choice of the optimum pumping geometries and crystal dimensions as the understanding of this laser system matures. We will also present some laser performance measurements for this system. Finally, we will compare the energy levels of several d2 transition metal ions and attempt to show the relationships and correlations between them.

Abstract:
The 2019 age-adjusted natural-cause mortality (NCM) rate for the prime working-age population (aged 25-54) was 43 percent higher in rural (nonmetropolitan) areas than in urban (metropolitan) areas. This is a shift from 25 years ago when NCM rates in urban and rural areas were similar for this age group. As a first step to understanding the increasing gap between rural and urban NCM rates, this report examines natural (disease-related) deaths for prime working-age adults in rural and urban areas between 1999 and 2019 using data from the U.S. Department of Health and Human Services, Centers for Disease Control's Wide-ranging Online Data for Epidemiology Research (WONDER). Prime working-age NCM rates are examined for the population as a whole, as well as by sex, race and ethnicity, region, and State. Overall, both an increase in the rural, prime working-age NCM rates and a decrease in the corresponding urban rates are contributing to the growing mortality gap.--

Abstract:
Light capturing and energy conversion by PSI is one of the most fundamental processes in nature. In the heart of these adaptations stand PSI, PSII and their light harvesting antenna complexes. The main goal of this grant proposal was to obtain by X-ray crystallography information on the structure of plant photosystem I (PSI) and photosystem II (PSII) supercomplexes. We achieved several milestones along this line but as yet, like several strong laboratories around the world, we have no crystal structure of plant PSII. We have redesigned the purification and crystallization procedures and recently solved the crystal structure of the PSI supercomplex at 3.3 Å resolution. Even though this advance in resolution appears to be relatively small, we obtained a significantly improved model of the supercomplex. The work was published in J. Biol. Chem. (Amunts et al., 2010). The improved electron density map yielded identification and tracing of the PsaK subunit. The location of an additional 10 ß-carotenes, as well as 5 chlorophylls and several loop regions that were previously uninterruptable have been modeled. This represents the most complete plant PSI structure obtained thus far, revealing the locations of and interactions among 17 protein subunits and 193 non-covalently bound photochemical cofactors. We have continued extensive experimental efforts to improve the structure of plant PSI and to obtain PSII preparation amenable to crystallization. Most of our efforts were devoted to obtain well-defined subcomplexes of plant PSII preparations that are amenable to crystallization. We studied the apparent paradox of the high sensitivity of oxygen evolution of isolated thylakoids while BBY particles exhibit remarkable resilience to the same treatment. The integrity of the photosystem II (PSII) extrinsic protein complement as well as calcium effects arise from the Ca2+ atom associated with the site of photosynthetic water oxidation were investigated. This work provides deeper insights into the interaction of PsbO with PSII. Sight-directed mutagenesis indicated the location of critical sites involved in the stability of the water oxidation reaction. When combined with previous results, the data lead to a more detailed model for PsbO binding in eukaryotic PSII.

Abstract:
This paper's main concern is to assess which "industrial policies" would be meaningful for Latin America nowadays. The first section introduces the theme while the second section considers definitions of "industrial policies" and their nature in the past. The third section centers on national growth experiences that may serve as paradigms. Section IV is on economies, which are growth paradigms, and on their policies. Section V is on present multilateral constraints on "industrial policies". Section VI explains the institution building, macroeconomics and industrial policies. Section VII analyses industrial policy alternatives. The paper concludes with section VIII that is on policy recommendations seeking to improve criteria to pick winners where market failures are especially costly.

Abstract:
U.S. policymakers need to understand the landscape of artificial intelligence talent and investment as AI becomes increasingly important to national and economic security. This knowledge is critical as leaders develop new alliances and work to curb China’s growing influence. As an initial effort, an earlier CSET report, “AI Hubs in the United States,” examined the domestic AI ecosystem by mapping where U.S. AI talent is produced, where it is concentrated, and where AI private equity funding goes. Given the global nature of the AI ecosystem and the importance of international talent flows, this paper looks for the centers of AI talent and investment in regions and countries that are key U.S. partners: Europe and the CANZUK countries (Canada, Australia, New Zealand, and the United Kingdom).

Abstract:
This special report discusses the outcomes of a September 2019 workshop intended to identify barriers to the consideration and implementation of natural and nature-based features (NNBF) in US Army Corps of Engineers (USACE) civil works projects. A total of 23 participants representing seven USACE districts, the US Army Engineer Research and Development Center (ERDC), and the University of California–Santa Cruz met at USACE’s South Atlantic Division Headquarters in Atlanta, Georgia, to discuss how to facilitate the implementation of NNBF into USACE project planning for wetlands and reefs using six categories: (1) site characterization, (2) engineering and design analysis, (3) life-cycle analysis, (4) economic analysis, (5) construction analysis, (6) and operation and maintenance (and monitoring). The workshop identified seven future directions in wetland and reef NNBF research and development: • Synthesize existing literature and analysis of existing projects to better define failure modes. • Determine trigger points that lead to loss of feature function. • Identify performance factors with respect to coastal storm risk management (CSRM) performance as well as ecological performance. • Focus additional research into cobenefits of NNBF. • Quantify the economic life-cycle costs of a project. • Improve technology transfer with regards to NNBF research and topics.

Abstract:
This technical note is part of a series collaboratively produced by the US Army Corps of Engineers (USACE)–Institute for Water Resources (IWR) and the US Army Engineer Research and Development Center (ERDC). It describes the funding and financing process for the South Bay Salt Pond Restoration Project in San Francisco Bay, California and, like the other technical notes in this series, documents successful examples of funding natural infrastructure projects. The research effort is a collaboration between the Engineering With Nature® (EWN®) and Systems Approach to Geomorphic Engineering (SAGE) programs of USACE. A key need for greater application of natural infrastructure approaches is information about obtaining funds to scope, design, construct, monitor, and adaptively manage these projects. As natural infrastructure techniques vary widely by location, purpose, and scale, there is no standard process for securing funds. The goal of this series is to share lessons learned about a variety of funding and financing methods to increase the implementation of natural infrastructure projects.
