description: We construct a theory of fields living on continuous geometries with fractional Hausdorff and spectral dimensions, focussing on a flat background analogous to Minkowski spacetime. After reviewing the properties of fractional spaces with fixed dimension, presented in a companion paper, we generalize to a multi-fractional scenario inspired by multi-fractal geometry, where the dimension changes with the scale. This is related to the renormalization group properties of fractional field theories, illustrated by the example of a scalar field. Depending on the symmetries of the Lagrangian, one can define two models. In one of them, the effective dimension flows from 2 in the ultraviolet (UV) and geometry constrains the infrared limit to be four-dimensional. At the UV critical value, the model is rendered power-counting renormalizable. However, this is not the most fundamental regime. Compelling arguments of fractal geometry require an extension of the fractional action measure to complex order. In doing so, we obtain a hierarchy of scales characterizing different geometric regimes. At very small scales, discrete symmetries emerge and the notion of a continuous spacetime begins to blur, until one reaches a fundamental scale and an ultra-microscopic fractal structure. This fine hierarchy of geometries has implications for non-commutative theories and discrete quantum gravity. In the latter case, the present model can be viewed as a top-down realization of a quantum-discrete to classical-continuum transition.

description: The influence of Atlantic sea surface temperature (SST) anomalies on the atmospheric circulation over the North Atlantic sector during winter is investigated by performing experiments with an atmospheric general circulation model. These consist of a 30-yr run with observed SST anomalies for the period 1961–90 confined geographically to the Atlantic Ocean, and of a control run with climatological SSTs prescribed globally. A third 30-yr integration with observed SSTs confined to the South Atlantic is made to confirm present findings. The simulated interannual variance of 500-hPa wintertime geopotential heights over the North Atlantic attains much more realistic values when observed Atlantic SSTs are prescribed. Circulation patterns that resemble the positive phase of the North Atlantic oscillation (NAO) become more pronounced in terms of the leading EOF of winter means, and a cluster analysis of daily fields. The variance of an interannual NAO index increases by fivefold over its control value. Atlantic SST variability is also found to produce an appreciable rectified response in the December–February time mean. Interannual fluctuations in the simulated NAO are found to be significantly correlated with SST anomalies over the tropical and subtropical South Atlantic. These SST anomalies are accompanied by displacements in the simulated summer monsoonal circulation over South America and the cross-equatorial regional Hadley circulation.
Securing Social Security for the Future

description: The funding troubles of Social Security have been greatly exaggerated in an effort to push a privatization agenda. Privatization has laudable goals--increased choice and higher returns--but few would choose to risk their secure retirement income and unfortunately higher returns cannot be achieved without risk. Regrettably, if private accounts really do offer a lot of choices, many people who cannot afford to do so will unwittingly risk their incomes; and, in many cases, a combination of this risk and high transaction costs will consume what should be their core retirement income. When the government picks up the pieces, the funding troubles will be worse, not better.

description: We introduce a set of iterative equations that exactly solves the size distribution of components on small arbitrary graphs after the random removal of edges. We also demonstrate how these equations can be used to predict the distribution of the node partitions (i.e., the constrained distribution of the size of each component) in undirected graphs. Besides opening the way to the theoretical prediction of percolation on arbitrary graphs of large but finite size, we show how our results find application in graph theory, epidemiology, percolation and fragmentation theory.

description: The primary goals of human civilization are sustainable growth and restoration of the ecosystem. Currently, the continuous release of effluents containing heavy metals from tanneries, and the mining, printing, and pharmaceutical industries into the aquatic environment has become a serious issue. Chromium (Cr) and mercury (Hg) pose a major threat to human beings. Several techniques have been employed to mitigate this threat, including adsorption, electrolysis, chemical precipitation, desalination, reverse osmosis, ion exchange, membrane filtration, and photocatalysis. However, photocatalysis is known for its cost-effectiveness and green aspects in the removal of heavy metal ions from solutions. Over the last few decades, there has been a growing interest among researchers worldwide to study this technique. Numerous materials, including conducting polymers (CPs), have been utilized for the removal of heavy metal ions from wastewater/aqueous solutions. Polyaniline (PANI)-based nanocomposites are effective photocatalysts for the removal of various types of heavy metal ions from wastewater/aqueous solutions. Despite its potential, several factors affect the removal efficiency, such as irradiation levels and the type of PANI-based nanocomposite used. Further research is needed to address these challenges and improve the stability and reusability of PANI-based photocatalysts. Given the available water resources in the real world, it is critical that in-depth research be conducted into PANI-based photocatalysts, and the stability and reusability of such catalysts and achieving the primary goals of human civilization, namely sustainable growth and ecosystem restoration.

description: BACKGROUND: We previously reported that integrating antiretroviral therapy (ART) with tuberculosis treatment reduces mortality. However, the timing for the initiation of ART during tuberculosis treatment remains unresolved. METHODS: We conducted a three-group, open-label, randomized, controlled trial in South Africa involving 642 ambulatory patients, all with tuberculosis (confirmed by a positive sputum smear for acid-fast bacilli), human immunodeficiency virus infection, and a CD4+ T-cell count of less than 500 per cubic millimeter. Findings in the earlier-ART group (ART initiated within 4 weeks after the start of tuberculosis treatment, 214 patients) and later-ART group (ART initiated during the first 4 weeks of the continuation phase of tuberculosis treatment, 215 patients) are presented here. RESULTS: At baseline, the median CD4+ T-cell count was 150 per cubic millimeter, and the median viral load was 161,000 copies per milliliter, with no significant differences between the two groups. The incidence rate of the acquired immunodeficiency syndrome (AIDS) or death was 6.9 cases per 100 person-years in the earlier-ART group (18 cases) as compared with 7.8 per 100 person-years in the later-ART group (19 cases) (incidence-rate ratio, 0.89; 95% confidence interval [CI], 0.44 to 1.79; P=0.73). However, among patients with CD4+ T-cell counts of less than 50 per cubic millimeter, the incidence rates of AIDS or death were 8.5 and 26.3 cases per 100 person-years, respectively (incidence-rate ratio, 0.32; 95% CI, 0.07 to 1.13; P=0.06). The incidence rates of the immune reconstitution inflammatory syndrome (IRIS) were 20.1 and 7.7 cases per 100 person-years, respectively (incidence-rate ratio, 2.62; 95% CI, 1.48 to 4.82; P<0.001). Adverse events requiring a switching of antiretroviral drugs occurred in 10 patients in the earlier-ART group and 1 patient in the later-ART group (P=0.006). CONCLUSIONS: Early initiation of ART in patients with CD4+ T-cell counts of less than 50 per cubic millimeter increased AIDS-free survival. Deferral of the initiation of ART to the first 4 weeks of the continuation phase of tuberculosis therapy in those with higher CD4+ T-cell counts reduced the risks of IRIS and other adverse events related to ART without increasing the risk of AIDS or death.

description: We consider SUSY extensions of the standard model where the gravitino is the dark-matter particle and the stau is long lived. If there is a significant mass gap with squarks and gluinos, the staus produced at hadron colliders tend to be fast (beta>0.8), and the searches based on their delay in the time of flight or their anomalous ionization become less effective. Such staus would be identified as regular muons with the same linear momentum and a slightly reduced energy. Compared to the usual SUSY models where a neutralino is the LSP, this scenario implies (i) more leptons (the two staus at the end of the decay chains), (ii) a strong e-mu asymmetry, and (iii) less missing E_T (just from neutrinos, as the lightest neutralino decays into stau). We study the bounds on this SUSY from current LHC analyses (same-sign dileptons and multilepton events) and discuss the best strategy for its observation.

Subjects: адвокаты; профессиональное выгорание адвокатов; психологические проявления

description: Введение. Представлены результаты эмпирического психологического исследования профессионального выгорания адвокатов. Целью послужило установление степени профессионального выгорания, деформации и деструкции адвоката посредством определения путей преодоления профессионального выгорания адвокатов и, как следствие, выявление способов повышения эффективности адвокатской деятельности. Материалы и методы. Использовались две методики психологической диагностики: основная — методика В. В. Бойко и контрольная — методика К. Маслач и С. Джексона в адаптации Н. Е. Водопьяновой. По основной методике опрошены 45 адвокатов, по контрольной — 47 адвокатов, имеющих стаж от 1 года до 10 лет, не пересекающихся между собой. Для оценки результатов применялись методы математической статистики. Результаты и обсуждение. Определены основные психологические аспекты проявления профессионального выгорания адвокатов при осуществлении адвокатской деятельности, в поведении и отношениях, а также психологические связи. Профессиональное выгорание адвокатов проявляется в неадекватном избирательном эмоциональном реагировании; редукции профессиональных обязанностей; расширении сферы экономии эмоций; переживании психотравмирующих обстоятельств; личностной отстраненности как деперсонализации. Наиболее стабильными проявлениями профессионального выгорания адвокатов выступают эмоциональная отстраненность, неудовлетворенность собой, эмоционально-нравственная дезориентация, психосоматические нарушения. Выводы. Подтверждается факт широкой распространенности у адвокатов профессионального выгорания. Профессиональное выгорание начинается с нарушений в эмоциональной сфере личности адвокатов. Решение проблем, связанных с повышением эффективности деятельности адвокатов, должно базироваться на точном и полном представлении психологических особенностей как субъектов профессиональной деятельности.

description: In savannah ecosystems, annual photosynthetic cycles are conspicuous from leaf to landscape level, introducing substantial temporal variability in the quality and quantity of forage plants. As such, the life histories and health of herbivores should be tightly coupled to seasonal phenological patterns; and occurrence patterns of infectious diseases may be driven by the resulting fluctuations in animal immune status. However, few longitudinal datasets including measures of forage quality, along with physiological, immunological and disease outcomes for ungulate consumers have yet been available to test this idea. In this work we used a novel dietary metric, faecal chlorophyll, to show that African buffalo (Syncerus caffer caffer) are highly sensitive to variation in primary production. We demonstrate that faecal chlorophyll correlates tightly with faecal nitrogen, which is often used to evaluate nutritional condition in ungulates; however, faecal chlorophyll assays are far more economical to run. We employ time lagged cross-correlation functions to explore its relationship with various environmental, physiological and immunological parameters and their outcomes for buffalo physiological condition and susceptibility to disease. Our results suggest that primary production is an overwhelming explanatory variable driving broad population level patterns of physiological condition, susceptibility to parasites, disease prevalence and the synergistic outcomes of these on buffalo health. Such strong links to environmental variability have cascading implications for disease dynamics and how we model the spread and maintenance of diseases in ungulate populations. We discuss the implications of this work for evaluating the vulnerability of buffalo to changes in climate, land use or management.

description: Введение. Целью исследования послужило выявление характеристик и элементов профессиональной деформации в условиях современной реальности для дальнейшего использования в работе психологов и непосредственных руководителей сотрудников полиции. Материалы и методы. Применялись методы анализа научной литературы, а также методы анкетирования и интервьюирования. В исследовании, проведенном в 2019 г., приняли участие 42 слушателя факультета заочного обучения и 96 слушателей факультета профессиональной подготовки на базе Сибирского юридического института МВД России (Красноярск). Результаты и обсуждение. Рассмотрены особенности проявления таких факторов профессиональной деформации, как эмоциональная черствость, коммуникативная скупость, чрезмерная критичность восприятия информации, доминирование интересов службы над личными, пренебрежение нормами этики (права). Выделены индикаторы, указывающие на наличие у сотрудника полиции профессиональной деформации, а также особенности ухода от раздражителей, вызывающих профессиональную деформацию у сотрудников полиции женского пола: повышенная конфликтность по вертикали и по горизонтали, эмоциональная ригидность, уход от проблемы без ее фактического преодоления. Выводы. Профессиональная деформация — сложное длящееся явление, которое имеет динамику изменения и современные особенности проявления. Профилактика профессиональной деформации должна носить не только общий, но и индивидуальный характер при реальном понимающем участии непосредственного руководителя.

В обследовании приняли участие 50 сотрудников органов внутренних дел, средний возраст испытуемых — 27,2 года, средний стаж службы — 3,1 ± 2,2 года. Применялись методики «Эмоциональное выгорание», «Фигуры Готтшальдта», «Готовность к экстремальному действию», «Кольца Ландольта», «Память на лица», «Память на время». Использовался корреляционный анализ по Г. Спирмену. Результаты и обсуждение. Выгорание рассматривалось с позиции «эмоционального истощения», «деперсонализации» и «редукции». Специфика корреляционных плеяд, отражающих взаимосвязь симптомов эмоционального выгорания фазы «напряжение» с психофизиологическими показателями, свидетельствуют об эффективном противодействии сотрудников полиции негативным психотравмирующим обстоятельствам. Корреляционные взаимосвязи изучаемых показателей в фазе «резистенция» говорят о снижении психоэмоционального фона, эмоциональном перенасыщении и равнодушии сотрудников полиции, в фазе «истощение» — о снижении памяти на лица и ухудшении точности слежения и целевой точности. Выводы. Установленные сдвиги психофизиологических показателей, характерные для фаз эмоционального выгорания «резистенция» и «истощение», могут быть включены в диагностику и профилактику психоэмоционального состояния и программу восстановления нервно-психических ресурсов.

description: Time boundary terms usually added to action principles are systematically handled in the framework of Dirac's canonical analysis. The procedure begins with the introduction of the boundary term into the integral Hamiltonian action and then the resulting action is interpreted as a Lagrangian one to which Dirac's method is applied. Once the general theory is developed, the current procedure is implemented and illustrated in various examples which are originally endowed with different types of constraints.

description: Background: In settings where multiple HIV prevention trials are conducted in close proximity, trial participants may attempt to enroll in more than one trial simultaneously. Co-enrollment impacts on participant's safety and validity of trial results. We describe our experience, remedial action taken, inter-organizational collaboration and lessons learnt following the identification of co-enrolled participants. Experiences: Between February and April 2008, we identified 185 of the 398 enrolled participants as ineligible. In violation of the study protocol exclusion criteria, there was simultaneous enrollment in another HIV prevention trial (ineligible co-enrolled, n = 135), and enrollment of women who had participated in a microbicide trial within the past 12 months (ineligible not co-enrolled, n = 50). Following a complete audit of all enrolled participants, ineligible participants were discontinued via study exit visits from trial follow-up. Custom-designed education program on co-enrollment impacting on participants' safety and validity of the trial results was implemented. Shared electronic database between research units was established to enable verification of each volunteer's trial participation and to prevent future co-enrollments. Lessons learnt: Interviews with ineligible enrolled women revealed that high-quality care, financial incentives, altruistic motives, preference for sex with gel, wanting to increase their likelihood of receiving active gel, perceived low risk of discovery and peer pressure are the reasons for their enrollment in the CAPRISA 004 trial. Conclusion: Instituting education programs based on the reasons reported by women for seeking enrollment in more than one trial and using a shared central database system to identify co-enrollments have effectively prevented further co-enrollments.

description: Введение. Описаны понятие профессиональной мотивации, ее структура и роль в становлении будущих сотрудников полиции. Цель исследования — эмпирически выявить состояние профессиональной мотивации, а также ее психологические особенности, препятствующие активизации познавательной активности в процессе учебы курсантов. Материалы и методы. В исследовании приняли участие курсанты 2‑го курса разных факультетов образовательной организации МВД России в количестве 61 человека. Для изучения особенностей мотивов профессиональной деятельности были использованы диагностическая методика Э. Шейна и методика диагностика мотивации достижения А. Мехрабиана, для выявления психологических особенностей профессионально-нравственных мотивов курсантов применялась методика Я. В. Подоляка. Результаты и обсуждение. Рассмотрены различные аспекты профессиональной мотивации курсантов. Имеющиеся теоретические подходы позволили эмпирически выявить выраженность определенных мотивов их основной деятельности — обучения в вузе, а также профессионально-нравственных мотивов, по сути, ценностных ориентаций, выступающих одним из структурных элементов профессиональной мотивации. Выводы. Отсутствие стремления к профессиональной компетентности как ведущего мотива профессиональной деятельности представляет неблагоприятный прогноз относительно устойчивости профессиональной направленности курсантов. Установлены психологические особенности, препятствующие активизации познавательной активности в процессе учебы курсантов, такие как отсутствие интереса к карьерному росту и управленческой деятельности, наличие стремления освободиться от организационных правил и ограничений в сочетании с готовностью вступать в конфронтацию и соперничество.

description: Nano CaCO3 (nC), various polymer mediated nano CaCO3 and Eu3+ anchored nano CaCO3/PEG were synthesized from natural carbonate source (Dolomite) (CaMg(CO3)2) using a novel, low cost, non-toxic and effective route biomimetic synthesis. The mineralogy, structural, thermal stability, and morphology analysis of the products were assessed through FTIR, XRD, TG-DTA, FE-SEM with EDX mapping, and HR-TEM with SAED. Results show that the prepared samples were in the form of calcite with rhombohedral (25-36 nm) structure. The prepared products exhibit good thermal stability up to 844° C. The products show a spherical and porous like structure. The elemental compositions of the products were confirmed through EDX analysis. All the plane values (observed from SAED) were matched with XRD results. An increase of Eu3+ in CaCO3 shows that the absorption and emission peaks are blue shifted and the band gap values are red shifted. The measured photoluminescence quantum yield values of 0.02 Eu3+:CaCO3/PEG (nCE1) and 0.08 Eu3+: CaCO3/PEG (nCE4) are 21% and 19%, respectively. Finally, the products (nC, nCE1, and nCE4) were subjected to photodegradation application and results shows that nCE1 has good photocatalytic activity against methylene blue (87%) for 90 min.
On Selective Indirect Tax Reform in Developing Countries
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University

Subjects: Economics

description: The current consensus on indirect tax reform in developing countries favors a reduction in trade taxes with an increase in VAT to raise revenue. The theoretical results on selective reform that underlie this consensus are, however, derived from partial models that ignore the existence of an informal economy. Once the incomplete coverage of VAT due to an informal economy is acknowledged, we show that, contrary to the current consensus, the standard revenue-neutral selective reform of trade taxes and VAT reduces welfare under plausible conditions. Moreover, a VAT base broadening with a revenue-neutral reduction in trade taxes may also reduce welfare. The results raise serious doubts about the wisdom of the indirect tax reform policies pursued by a large number of developing countries.

description: Understanding the social organization of elusive forest-dwelling ungulates may have important conservation and management implications. We present a comparison of grouping patterns in forest buffalo across different sites and through time in Central African rainforest. We examined five sites: Mbeli Bai and Bonye Bai (Nouabalé-Ndoki National Park, Republic of Congo), Dzanga Bai and Bai-Hokou (Dzanga-Ndoki National Park, C.A.R.) and Lopé-Okanda National Park (Gabon).Buffalo showed high site fidelity to open areas, including forest clearings. Forest buffalo herds (mean 12 ind. ± SD; range 3-24) were much smaller than records of savanna buffalo herds (mean 350 ind. ± SD; range 12-1500>), but also showed frequently fission-fusion patterns. Data from Mbeli Bai collected from 2012 to 2016confirm a stable presence of two buffalo herds (range 9-10 ind.) with occasional visits by lone individuals. Observations from Dzanga Bai over a period of 10 years (2006-2016) confirm the occurrence of only one buffalo herd (range 8-10ind.). In Bai-Hokou site, a single buffalo herd increased from 16 to 24 individuals during a three year period (2001-2004). Finally in Lopé National Park (a mosaic of savanna and forest fragments), the mean group size for 18 herds monitored from2002 to 2004 was 12±2 ind. (range of means=3–24). We analysed if herd size and herd stability are affected by clearing size, clearing type (e.g. marsh or land) and grass coverage across different sites and through time.

description: In this work, we first propose the isovector $nD^{*}_0(2400)^0$ molecular state to explain the enhancement structure around 3250 MeV ($X_c(3250)^0$) in the $Σ_c^{++}π^-π^-$ invariant mass spectrum newly observed by the BaBar Collaboration. Under this molecular state configuration, both the analysis of the mass spectrum and the study of its dominant decay channel can well depict its resonance parameters measured by BaBar. Our investigation also shows that the isovector $nD^{*}_0(2400)^0$ molecular state can decay into $Σ_c^{++}π^-π^-$, which is consistent with the experimental observation. These studies provide the direct support to the isovector $nD^{*}_0(2400)^0$ molecular state assignment to $X_c(3250)^0$.

description: Continuum fitting is an important aspect of Lyman-alpha forest science, since errors in the estimated optical depths scale with the fractional continuum error. However, traditional methods of estimating continua in noisy and moderate-resolution spectra (S/N < 10 pixel^-1 and R ~ 2000, respectively, such as SDSS) using power-law extrapolation or the mean spectrum, achieve no better than ~ 10-15% RMS accuracy. To improve on this, we introduce mean-flux regulated/principal component analysis (MF-PCA) continuum fitting. In this technique, PCA fitting is carried out redwards of the quasar Lyman-alpha line in order to provide a prediction for the shape of the Lyman-alpha forest continuum. The slope and amplitude of this continuum prediction is then corrected using external constraints for the Lyman-alpha forest mean-flux. From tests on mock spectra, we find that MF-PCA reduces the errors to 8% RMS in S/N ~ 2 spectra, and < 5% RMS in spectra with S/N > 5. The residual Fourier power in the continuum is decreased by a factor of a few in comparison with dividing by the mean continuum, enabling Lyman-alpha flux power spectrum measurements to be extended to ~2x larger scales. Using this new technique, we make available continuum fits for 12,069 z>2.3 Lyman-alpha forest spectra from SDSS DR7 for use by the community. This technique is also applicable to future releases of the ongoing BOSS survey, which is obtaining spectra for ~ 150,000 Lyman-alpha forest spectra at low signal-to-noise (S/N ~ 2).

The role of SHIP in natural killer cell licensing
Creators: name: Rytova, Valeria
Publisher: name: University of British Columbia
Year: 2011

description: Natural Killer (NK) cells comprise a unique subset of lymphocytes with innate ability to detect and kill abnormal cells. Inhibitory Ly49 receptors expressed on NK cells recognize major histocompatibility complex class I (MHC I) molecules and inhibit NK cell killing of normal cells that express high amounts of MHC I. In addition to maintaining self-tolerance of NK cells, the Ly49:MHC I interaction is required for the functional maturation of NK cells by a process termed “NK cell licensing.” NK cells from MHC I-deficient β2 microglobulin (β2m)-KO mice are not cytotoxic as they are not licensed. Our goal was to determine the mechanism through which NK cells of MHC-I deficient mice are kept hyporesponsive to NK-sensitive targets. We compared unlicensed NK cells from β2m-KO mice with licensed wild type (WT) NK cells in each step of NK cell cytotoxicity. We found that LFA-1 mediated adhesion to target and polarization of actin and talin are functional in these cells, yet unlicensed NK cells fail to polarize cytotoxic granules when bound to the prototypic NK target YAC-1, or beads coated with combinations of ligands for NK stimulatory receptors, namely the LFA-1 ligand ICAM-1, NKG2D ligand H60, and 2B4 ligand CD48. Thus, NKG2D and 2B4 mediated signalling seemed impaired in unlicensed NK cells. Ly49 receptors, upon tyrosine phosphorylation, are thought to recruit both Src homology 2-containing phosphatase 1 (SHP1) and Src homology 2 domain-containing inositol-5′-phosphatase (SHIP), whereas NK cell licensing is known to be SHP1-independent. Therefore, we tested whether SHIP is involved in NK cell licensing. In both WT and β2m-KO NK cells, antibody mediated cross-linking of inhibitory Ly49 receptors induced recruitment of SHIP rather than SHP1. When NK cells bound to MHC I-deficient YAC-1, SHIP was enriched at the contact site of unlicensed, but not in licensed, NK cells. These results suggest that during the process of NK cell licensing, Ly49C/I recruits SHIP and prevents SHIP’s association with activating NK cell receptors allowing stimulatory signalling and cytotoxicity to occur. These findings provide insight into the mechanism of NK cell licensing and signalling generated by the Ly49: MHC I interaction.

description: Введение. Личность субъекта экстремальной деятельности не всегда в полной мере соответствует реальным требованиям, запросам деятельности. Прогнозирование его адаптации невозможно без разделения психологических условий и факторов данного процесса. Эта проблема носит теоретико-методологический характер и обусловлена отсутствием единого подхода к оценке личности будущих субъектов экстремальной деятельности. Цель — обоснование условий и факторов прогнозирования адаптации личности будущих субъектов экстремальной деятельности. Материалы и методы. Исследование предусматривает сбор, обобщение и анализ накопленного в рамках различных подходов к указанной области знания научного материала. Использовались результаты диагностики по методикам «Адаптивность», «УСК», «Самооценка» (модифицированный автором вариант), проведенной в отношении студентов специальностей «Пожарная безопасность», «Защита в чрезвычайных ситуациях» Ульяновского государственного университета и курсантов Академии ФСИН России в количестве 155 человек. Результаты и обсуждение. Анализ условий и факторов прогнозирования адаптации личности будущих субъектов экстремальной деятельности показал, что их разделение возможно по временному признаку, постоянству и силе воздействия, объективности– субъективности. При этом классификация носит незавершенный характер, может быть дополнена. На эмпирическом уровне в качестве факторов выделяются особенности личности, в частности адекватность самооценки, нервно-психическая устойчивость, интернальность–экстернальность. Выводы. Анализ условий и факторов адаптации личности будущих субъектов экстремальной деятельности показал, что их влияние в первую очередь обусловлено системой «личность — деятельность — ситуация».

description: Oxygen is in many ways a unique element: the only known diatomic molecular magnet and the capability of stabilization of the hitherto unexpected O8 cluster structure in its solid form at high pressure. Molecular dissociations upon compression as one of the fundamental problems were reported for other diatomic solids (e.g., H2, I2, Br2, and N2), but it remains elusive for solid oxygen, making oxygen an intractable system. We here report the theoretical prediction on the dissociation of molecular oxygen into a polymeric spiral chain O4 structure (θ-O4) by using first-principles calypso method on crystal structure prediction. The θ-O4 stabilizes above 2 TPa and has been observed as the third high pressure phase of sulfur (S-III). We find that the molecular O8 phase remains extremely stable in a large pressure range of 0.008 - 2 TPa, whose breakdown is driven by the pressure-induced instability of a transverse acoustic phonon mode at zone boundary, leading to the ultimate formation of θ-O4. Remarkably, stabilization of θ-O4 turns oxygen from a superconductor into an insulator with a wide band gap (approximately 5.9 eV) originating from the sp3-like hybridized orbitals of oxygen and the localization of valence electrons.
