description: The Irano-Turanian (IT) floristic region in Asia contains three biodiversity hotspots and has been a source of xerophytic taxa for neighboring regions. Despite its species richness and large territory, the evolutionary history and biogeography of this floristic region is poorly understood. Acanthophyllum, encompassing ca. 70 subshrubby mostly thorny-cushion species, is one of the important components of the steppe and mountain vegetation of this region. In this study, we investigate the tempo and mode of diversification as well as the biogeographic patterns of this genus. The ancestral area analysis suggests that Acanthophyllum originated east of the Zagros Mountains in the Miocene, from where it expanded westwards. A shift in the speciation rate in the late Pliocene (ca. 3.24 Ma) was detected, based on a nrDNA ITS tree, affecting the lineage of the largest section in the genus, Acanthophyllym sect. Oligosperma. Parallelisms with another IT species-rich genera in aspects such as largely coincident ranges and habitats, presence of a thorny-cushion life-form, similar areas reconstructed for their MRCA, and the inference of a shift in speciation in the region suggest common underlying abiotic and biotic factors or even drivers for diversification and speciation in the high elevation dry continental landscape of IT region.

description: We relate notions of complementarity in three layers of quantum mechanics: (i) von Neumann algebras, (ii) Hilbert spaces, and (iii) orthomodular lattices. Taking a more general categorical perspective of which the above are instances, we consider dagger monoidal kernel categories for (ii), so that (i) become (sub)endohomsets and (iii) become subobject lattices. By developing a `point-free' definition of copyability we link (i) commutative von Neumann subalgebras, (ii) classical structures, and (iii) Boolean subalgebras.

description: Intercropping is a common agricultural practice improving acquisition of nutrients including iron (Fe). The mechanisms behind this effect, however, are still poorly understood particularly when intercropping cereals with non-legume dicots. To explore the role of root exudates in this positive interaction, oilseed rape (Brassica napus) and barley (Hordeum vulgare) were cultivated in hydroponics either as intercrop (IC) or monocrop (MC) under Fe-sufficient (+Fe) or Fe-deficient (–Fe) conditions. Intercropping improved chlorophyll (Chl) concentration, photosynthesis rates and the “active Fe” concentration in the young leaves of –Fe oilseed rape. Additionally, intercropping under Fe deficiency enhanced the root Fe-reductase activity and the release of organic acids and phenolic compounds by oilseed rape and the release of phytosiderophores by the barley plants. Resupply of sparingly soluble Fe(OH)3 to –Fe plants improved leaf Chl and increased the Fe concentration of barley plants under both MC and IC. Contrastingly, oilseed rape was able to use Fe(OH)3 only under IC conditions. Moreover, oilseed rape-barley intercropping under + Fe conditions also improved Chl, photosynthesis and nitrogen uptake in oilseed rape. This positive effect of IC independent from Fe acquisition makes intercropping an attractive practice even under non-Fe stress conditions.

description: It’s spring break and I’m ostensibly on vacation. This means I’m working, but I’m doing so while looking at the ocean and as a marine biologist that’s not a bad way to do things. While checking Twitter this morning I saw an article in the Journal of Proteomics raising a stir. Like many journals JoP has graphical abstracts, essentially a single figure which is supposed to best sum up the science being done.  The reason why this article was causing a stir had absolutely nothing to do with the science, rather the authors had decided that a scantly clad woman holding two coconuts would be the best way to describe the science contained in “Harry Belafonte and the secret proteome of coconut milk”.

description: The beneficial effect of antihypertensive medication on reducing the risk of cardiovascular disease (CVD) events is supported by data from randomized controlled trials of older adults with hypertension. However, in clinical practice, overtreatment of hypertension in older adults may lead to side effects and an increased risk of falls. The diagnosis and treatment of hypertension is primarily based on blood pressure measurements obtained in the clinic setting. Ambulatory blood pressure monitoring (ABPM) complements clinic blood pressure by measuring blood pressure in the out-of-clinic setting. ABPM can be used to identify white coat hypertension, defined as elevated clinic blood pressure and non-elevated ambulatory blood pressure. White coat hypertension is common in older adults but does not appear to be associated with an increased risk of CVD events among this population. Herein, we review the current literature on ABPM in the diagnoses of white coat hypertension in older adults, including its potential role in preventing overtreatment.

description: В статье авторы поднимают вопросы о продолжающемся воздействии на жизнь человека лишения его свободы и о том, каким образом эти бывшие места лишения свободы интерпретируются, посещаются, пропагандируются в качестве объектов назначения и, в конечном итоге, понимаются сегодня. В настоящее время войны, поля сражений, кладбища, концентрационные лагеря, тюрьмы, темницы, места убийств, истории о призраках и другие техногенные катастрофы упаковываются и представляются людям как туристическая достопримечательность. Притяжение смерти и катастрофы является мощным фактором мотивации для туристов. Тюремный туризм как подгруппа темного туризма сам по себе является важной областью наследия. В статье рассматриваются особенности тюремного туризма как одного из подвидов темного туризма. Тюрьмы – это места, где отбывают наказание много разных, не похожих друг на друга людей, а также концентрируются разные события: попытки побега, смерть, насилие, страдания – все это часть этих историй. При таком типе туризма бывшие места лишения свободы стали популярным туристическим опытом, поскольку дезактивированные тюрьмы превращаются в музеи или гостиничные объекты. В материале дифференцируются бывшие зарубежные тюрьмы, признанные объектами, представляющими наибольшую образовательную, экономическую и развлекательную ценность. Однако связывая тюремное заключение исключительно с прошлым, комментируя тюремный опыт и представляя исторический тюремный туризм как форму развлечения, исторические тюремные музеи уменьшают объективные реалии и человеческие издержки лишения свободы.

description: Gross Domestic Product (GDP) is broken. Still, we shouldn’t scrap GDP and start over. Up to a point, GDP does tell us important facts about people’s lives, livelihoods and aspirations. Living on a dollar a day is miserable no matter how you look at it.

Choking on economic growth, of course, is equally bad. There are a few simple, well-established steps we ought to take to bring GDP closer to where we should be. That, by the way, isn’t “Green GDP” or “green accounting.” It’s honest accounting.

description: A theory of spin-orbit coupling in bilayer graphene is presented. The electronic band structure of the AB bilayer in the presence of spin-orbit coupling and a transverse electric field is calculated from first principles using the linearized augmented plane-wave method implemented in the wien2k code. The first-principles results around the K points are fitted to a tight-binding model. The main conclusion is that the spin-orbit effects in bilayer graphene derive essentially from the single-layer spin-orbit coupling which comes almost solely from the d orbitals. The intrinsic spin-orbit splitting (anticrossing) around the K points is about 24 μeV for the low-energy valence and conduction bands, which are closest to the Fermi level, similarly as in the single-layer graphene. An applied transverse electric field breaks space inversion symmetry and leads to an extrinsic (also called Bychkov-Rashba) spin-orbit splitting. This splitting is usually linearly proportional to the electric field. The peculiarity of graphene bilayer is that the low-energy bands remain split by 24 μeV independently of the applied external field. The electric field, instead, opens a semiconducting band gap separating these low-energy bands. The remaining two high-energy bands are spin split in proportion to the electric field; the proportionality coefficient is given by the second intrinsic spin-orbit coupling, whose value is 20 μeV. All the band-structure effects and their spin splittings can be explained by our tight-binding model, in which the spin-orbit Hamiltonian is derived from symmetry considerations. The magnitudes of intra- and interlayer couplings—their values are similar to the single-layer graphene ones—are determined by fitting to first-principles results.

description: We study low-energy scattering of a neutral atom by a perfectly conducting cylindrical nanowire. Based on the exact atom-wire potential given recently by Eberlein and Zietal [ Phys. Rev. A 80 012504 (2009)] we derive tractable expressions for both the nonretarded van der Waals limit and the highly retarded limit as well as a realistic description of the transition between these two limits. For real atoms and wire radii greater than a few atomic units, the nonretarded van der Waals limit is insufficient, whereas the highly retarded limit of the atom-wire potential gives an accurate description of low-energy elastic scattering and absorption cross sections.
Performance analysis of an interacting quantum dot thermoelectric setup

description: In the absence of phonon contribution, a weakly coupled single orbital noninteracting quantum dot thermoelectric setup is known to operate reversibly as a Carnot engine. This reversible operation, however, occurs only in the ideal case of vanishing coupling to the contacts, wherein the transmission function is delta shaped, and under open-circuit conditions, where no electrical power is extracted. In this paper, we delve into the thermoelectric performance of quantum dot systems by analyzing the power output and efficiency directly evaluated from the nonequilibrium electric and energy currents across them. In the case of interacting quantum dots, the onequilibrium currents in the limit of weak coupling to the contacts are evaluated using the Pauli master equation approach. The following fundamental aspects of the thermoelectric operation of a quantum dot setup are discussed in detail: (a) With a finite coupling to the contacts, a thermoelectric setup always operates irreversibly under open-circuit conditions, with a zero efficiency. (b) Operation at a peak efficiency close to the Carnot value is possible under a finite power operation. In the noninteracting single orbital case, the peak efficiency approaches the Carnot value as the coupling to the contacts becomes smaller. In the interacting case, this trend depends nontrivially on the interaction parameter U. (c) The evaluated trends of the maximum efficiency derived from the nonequilibrium currents deviate considerably from the conventional figure of merit zT -based results. Finally, we also analyze the interacting quantum dot setup for thermoelectric operation at maximum power output.

description: The Major Highlands of Abruzzo is one of the largest and best preserved areas with marsh vegetation in the Apennines. Fairly well known similar plant systems extend from the Umbrian-Marche Apennines to those of the Matese. The marshy and wet vegetation of the large sedge vegetation (Magnocaricetalia) of the “Major Highlands of Abruzzo” is analysed. Other ecotonal or transitional plant communities mainly characterised by smaller sedges are also included in this study. Fifteen vegetation types have been identified, belonging to the following higher syntaxa: (1) Magnocaricetalia (Caricetum gracilis, Caricetum vulpinae, Caricetum vesicariae, Galio palustris-Caricetum buxbaumii ass. nova, Caricetum ripariae, Caricetum distichae, and Caricetum paniculatae); (2) Caricetalia davallianae (Carex fusca community); (3) Eleocharito palustris-Sagittarion sagittifoliae (Eleocharitetum palustris); (4) Potentillion anserinae (Carex panicea and C. tomentosa communities, Ranunculo repentis-Caricetum divisae ass. nova, and Ranunculo acri-Caricetum hirtae); (5) Cynosurion cristati (Carex leporina and C. spicata communities). Nine of these communities are new for the investigated area and seven of them are new for the Abruzzo region. Several of the associations are very rare in Central and Southern Apennines and many endangered plant species are linked to them. Nevertheless, these vegetation types are not sufficiently protected today, especially those outside the National Parks.

description: The capacitive couplings between gate-defined quantum dots and their gates vary considerably as a function of applied gate voltages. The conversion between gate voltages and the relevant energy scales is usually performed in a regime of rather symmetric dot-lead tunnel couplings strong enough to allow direct transport measurements. Unfortunately, this standard procedure fails for weak and possibly asymmetric tunnel couplings, often the case in realistic devices. We have developed methods to determine the gate voltage to energy conversion accurately in the different regimes of dot-lead tunnel couplings and demonstrate strong variations of the conversion factors. Our concepts can easily be extended to triple quantum dots or even larger arrays.

Exploring the determinants of parental disciplinary behaviour : the robustness of child characteristics
Creators: name: Hochbaum, Christine V.
Publisher: name: University of British Columbia
Year: 2017

description: Since the 1970’s, there has been a burgeoning interest about the potential effects of children on parents. Theoretical approaches that reflect this interest include Bell’s (1974, 1977) control theory, the writings of Ambert (1992, 2001), genetic-mediation models (Jaffee, Caspi, Moffitt, Polo-Tomas, Price, & Taylor 2004; Knafo & Plomin, 2006; Reiss, 1995), and frameworks emphasizing parental cognition (Dix, 1991; Dix & Grusec, 1985; Dix, Ruble, & Zarnbarano, 1989; Maccoby & Martin, 1983; Okagaki & Divecha, 1993; Peterson & Rollins, 1987).The “child effects” perspective focuses on understanding how and why children affect their parents. The objective of this study was to investigate the extent to which parental disciplinary behaviours are determined by child characteristics. It further sought to explore whether or not variations in child characteristics over time influence parental disciplinary behaviours. This study uses data from the first three cycles of the National Longitudinal Survey of Children and Youth (NLSCY, 1994-98). The sample was restricted to children 0-11 years old at Cycle 1 whose biological mother completed the survey in all three cycles (N = 11,780). Multiple linear regression was employed to test if the criterion measures of physical-psychological aggressive discipline, privilege deprivation-diversion, and reward were a function of child characteristics after accounting for parent, familial, and contextual covariates. The results showed that child social competence was negatively related to physical-psychological aggressive discipline and privilege deprivation-diversion as well as positively associated with reward. In addition to experiencing less reward, children reported as high in externalizing problems and difficult temperament received one or both physical-psychological aggressive discipline and privilege deprivation-diversion more often than children reported as low in these behaviours. All measures of discipline were inversely related to social unresponsiveness and inactivity (i.e., dull temperament; Bates, Freeland, & Lounsbury, 1979), while internalizing behaviours were negatively related only to privilege deprivation-diversion and reward. Child characteristics that represented slow development were negatively associated with privilege deprivation-diversion and reward. Preliminary evidence was obtained indicating that mothers administered increased physical-psychological aggressive discipline and privilege deprivation-diversion to children who developed high levels of externalizing behaviours compared to those who remained low in these behaviours.

description: Lower adherence to antihypertensive medications may increase visit-to-visit variability of blood pressure (VVV of BP), a risk factor for cardiovascular events and death. We used data from the African American Study of Kidney Disease and Hypertension (AASK) trial to examine whether lower medication adherence is associated with higher systolic VVV of BP in African Americans with hypertensive chronic kidney disease (CKD). Determinants of VVV of BP were also explored. AASK participants (n=988) were categorized by self-report or pill count as having perfect (100%), moderately high (75–99%), moderately low (50–74%) or low ( < 50%) proportion of study visits with high medication adherence over a 1-year follow-up period. We used multinomial logistic regression to examine determinants of medication adherence, and multivariable-adjusted linear regression to examine the association between medication adherence and systolic VVV of BP, defined as the coefficient of variation or the average real variability (ARV). Participants with lower self-reported adherence were generally younger and had a higher prevalence of comorbid conditions. Compared with perfect adherence, moderately high, moderately low and low adherence was associated with 0.65% (±0.31%), 0.99% (±0.31%) and 1.29% (±0.32%) higher systolic VVV of BP (defined as the coefficient of variation) in fully adjusted models. Results were qualitatively similar when using ARV or when using pill counts as the measure of adherence. Lower medication adherence is associated with higher systolic VVV of BP in African Americans with hypertensive CKD; efforts to improve medication adherence in this population may reduce systolic VVV of BP.

description: We study the conductance of graphene nanoribbons with long-range disorder. Due to the absence of intervalley scattering from the disorder potential, time-reversal symmetry (TRS) can be effectively broken even without a magnetic field, depending on the type of ribbon edge. Even though armchair edges generally mix valleys, we show that metallic armchair nanoribbons possess a hidden pseudovalley structure and effectively broken TRS. In contrast, semiconducting armchair nanoribbons inevitably mix valleys and restore TRS. As a result, in strong disorder metallic armchair ribbons exhibit a perfectly conducting channel, but semiconducting armchair ribbons ordinary localization. TRS is also effectively broken in zigzag nanoribbons in the absence of valley mixing. However, we show that intervalley scattering in zigzag ribbons is significantly enhanced and TRS is restored even for smooth disorder, if the Fermi energy is smaller than the potential amplitude. The symmetry properties of disordered nanoribbons are also reflected in their conductance in the diffusive regime. In particular, we find suppression of weak localization and an enhancement of conductance fluctuations in metallic armchair and zigzag ribbons without valley mixing. In contrast, semiconducting armchair and zigzag ribbons with valley mixing exhibit weak localization behavior.

description: Имеющийся пласт научных исследований, посвященных использованию, преобразованию и сохранению разнообразных объектов, относящихся к промышленному наследию, позволяет сделать вывод о ряде преференций, которые индустриальное наследие может дать промышленным регионам, таких, как культурная и экономическая валоризация промышленных зон и зданий, решение экосистемных и экологических проблем, способствование преемственности поколений и снятию социальной напряженности. Одним из основных направлений использования объектов наследия в настоящее время является туризм и экскурсионная деятельность. По публикациям в научной литературе и открытых источниках был проведен анализ опыта использования промышленного наследия. Проведены полевые исследования объектов промышленного наследия Тульской области, а также опрос экспертов и потенциальных потребителей услуг промышленного туризма. В качестве основных методов исследования были использованы общенаучный анализ и синтез, неструктурированное интервью, анкетный опрос, методы описательной статистики. Показано, что старопромышленные регионы имеют богатое культурно-историческое наследие, которое позволяет создавать туристические инфраструктурные комплексы, мультифункциональные кварталы и городские пространства, планировать однодневные и многодневные маршруты. Исследование предпочтений потенциальных потребителей туристских услуг показало, что наибольшим спросом пользуются программы, которые помимо объектов индустриального наследия включают действующие предприятия, реконструкции и музеи. Решения на основе технологий виртуальной и дополненной реальности могут составить альтернативу реконструкциям промышленных объектов. В техногенных ландшафтах потребителей привлекают нехарактерный для местности рельеф и «необычный вид». Перспективными программами промышленного туризма в Тульской области могут стать маршруты, связанные с развитием металлургии в регионе, а также включающие каменоломни в Венёвском районе и техногенный ландшафт «Романцевские горы» Узловского района. Исследование выполнено при финансовой поддержке РФФИ и Тульской области в рамках научного проекта № 19-410-710004.

description: Let R be the polynomial ring in n variables, acted on by the symmetric group S_n. Soergel constructed a full monoidal subcategory of R-bimodules which categorifies the Hecke algebra, whose objects are now known as Soergel bimodules. Soergel bimodules can be described as summands of Bott-Samelson bimodules (attached to sequences of simple reflections), or as summands of generalized Bott-Samelson bimodules (attached to sequences of parabolic subgroups). A diagrammatic presentation of the category of Bott-Samelson bimodules was given by the author and Khovanov in previous work. In this paper, we extend it to a presentation of the category of generalized Bott-Samelson bimodules. We also diagrammatically categorify the representations of the Hecke algebra which are induced from trivial representations of parabolic subgroups. The main tool is an explicit description of the idempotent which picks out a generalized Bott-Samelson bimodule as a summand inside a Bott-Samelson bimodule. This description uses a detailed analysis of the reduced expression graph of the longest element of S_n, and the semi-orientation on this graph given by the higher Bruhat order of Manin and Schechtman.

description: Decline in executive functioning (EF) is a hallmark of cognitive aging. We have previously reported that faster vagal recovery from cognitive challenge is associated with better EF. This study examined the association between vagal recovery from cognitive challenge and age-related differences in EF among 817 participants in the Midlife in the U.S. study (aged 35–86). Cardiac vagal control was measured as high-frequency heart rate variability. Vagal recovery moderated the association between age and EF (β = .811, p = .004). Secondary analyses revealed that older participants (aged 65–86) with faster vagal recovery had superior EF compared to their peers who had slower vagal recovery. In contrast, among younger (aged 35–54) and middle-aged (aged 55–64) participants, vagal recovery was not associated with EF. We conclude that faster vagal recovery from cognitive challenge is associated with reduced deficits in EF among older, but not younger individuals.

description: In the context of developing a hadron calorimeter with extremely fine granularity for the application of Particle Flow Algorithms to the measurement of jet energies at a future lepton collider, we report on extensive tests of a small scale prototype calorimeter. The calorimeter contained up to 10 layers of Resistive Plate Chambers (RPCs) with 2560 1 \times 1 cm2 readout pads, interleaved with steel absorber plates. The tests included both long-term Cosmic Ray data taking and measurements in particle beams, where the response to broadband muons and to pions and positrons with energies in the range of 1 - 16 GeV was established. Detailed measurements of the chambers efficiency as function of beam intensity have also been performed using 120 GeV protons at varying intensity. The data are compared to simulations based on GEANT4 and to analytical calculations of the rate limitations.

description: Background: Psychosocial risk for cardiovascular disease (CVD) may be especially deleterious in persons with low socioeconomic status. Most work has focused on psychosocial factors individually, but emerging research suggests that the confluence of psychosocial risk may be particularly harmful. Using data from the Reasons for Geographical and Racial Differences in Stroke (REGARDS) study, we examined associations among depressive symptoms and stress, alone and in combination, and incident CVD and all‐cause mortality as a function of socioeconomic status.

Methods and Results At baseline, 22 658 participants without a history of CVD (58.8% female, 41.7% black, mean age 63.9±9.3 years) reported on depressive symptoms, stress, annual household income, and education. Participants were classified into 1 of 3 psychosocial risk groups at baseline: (1) neither depressive symptoms nor stress, (2) either depressive symptoms or stress, or (3) both depressive symptoms and stress. Cox proportional hazards models were used to predict physician‐adjudicated incident total CVD events (nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death) and all‐cause mortality over a median of 7.0 years (interquartile range 5.4–8.3 years) of follow‐up. In fully adjusted models, participants with both depressive symptoms and stress had the greatest elevation in risk of developing total CVD (hazard ratio 1.48, 95% CI 1.21–1.81) and all‐cause mortality (hazard ratio 1.33, 95% CI 1.13–1.56) but only for those with low income (< $35 000) and not high (≥ $35 000) income. This pattern of results was not observed in models stratified by education.

Conclusions Findings suggest that screening for a combination of elevated depressive symptoms and stress in low‐income persons may help identify those at increased risk of incident CVD and mortality.

description: Lattice Yang-Mills theories in any dimension may be regarded as coupled 1+1-dimensional integrable field theories. These integrable systems decouple at large center-of-mass energies, where the action becomes effectively anisotropic. This effective action is the high-energy center-of-mass limit of the gauge theory. In 2+1 dimensions, the quark-antiquark potential and the mass spectrum can be calculated, using the exact 1+1-dimensional S-matrix and form factors. The methods are quite similar to those applying integrability in statistical and condensed-matter physics. The high-energy anisotropic action at one loop in 3+1 dimensions has been found using a Wilsonian renormalization method. We briefly discuss the isotropic theory in 2+1 dimensions and the connection with soft scattering in 3+1 dimensions.

description: The NIMH Research Domain Criteria (RDoC) initiative aims to describe key dimensional constructs underlying mental function across multiple units of analysis—from genes to observable behaviors—in order to better understand psychopathology. The acute threat (“fear”) construct of the RDoC Negative Valence System has been studied extensively from a translational perspective, and is highly pertinent to numerous psychiatric conditions, including anxiety and trauma-related disorders. We examined genetic contributions to the construct of acute threat at two units of analysis within the RDoC framework: (1) neural circuits and (2) physiology. Specifically, we focused on genetic influences on activation patterns of frontolimbic neural circuitry and on startle, skin conductance, and heart rate responses. Research on the heritability of activation in threat-related frontolimbic neural circuitry is lacking, but physiological indicators of acute threat have been found to be moderately heritable (35–50%). Genetic studies of the neural circuitry and physiology of acute threat have almost exclusively relied on the candidate gene method and, as in the broader psychiatric genetics literature, most findings have failed to replicate. The most robust support has been demonstrated for associations between variation in the serotonin transporter (SLC6A4) and catechol-O-methyltransferase (COMT) genes with threat-related neural activation and physiological responses. However, unbiased genome-wide approaches using very large samples are needed for gene discovery, and these can be accomplished with collaborative consortium-based research efforts, such as those of the Psychiatric Genomics Consortium (PGC) and Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Consortium. © 2015 Wiley Periodicals, Inc.

description: An $(f,g)$-semi-matching in a bipartite graph $G=(U \cup V,E)$ is a set of edges $M \subseteq E$ such that each vertex $u\in U$ is incident with at most $f(u)$ edges of $M$, and each vertex $v\in V$ is incident with at most $g(v)$ edges of $M$. In this paper we give an algorithm that for a graph with $n$ vertices and $m$ edges, $n\le m$, constructs a maximum $(f,g)$-semi-matching in running time $O(m\cdot \min (\sqrt{\sum_{u\in U}f(u)}, \sqrt{\sum_{v\in V}g(v)}))$. Using the reduction of [5], our result on maximum $(f,g)$-semi-matching problem directly implies an algorithm for the optimal semi-matching problem with running time $O(\sqrt{n}m \log n)$.

description: В статье поднимается актуальный вопрос, обусловленный существованием пробелов теоретического и прикладного характера при реализации устойчивого подхода применительно к развитию сферы туризма. В качестве основной цели исследования выступает детерминация совокупности факторов, определяющих устойчивое развитие туристско-рекреационного комплекса территории. Принимая во внимание тот факт, что развитие туристско-рекреационного комплекса в рамках конкретной территории характеризуется огромным количеством разнородных по своей природе элементов и взаимосвязей между ними, при отсутствии достаточной количественной информации о динамике процессов, был сделан вывод о том, что обеспечение устойчивого развития комплекса относится к разряду слабоструктурированных проблем и требует использования инновационных методов, подходов, инструментария. Поэтому в качестве основного инструментария исследования в рамках поставленного вопроса предлагается использовать методы когнитивной методологии, основанные на графическом и теоретико-множественном описании систем и позволяющие работать как с качественными, так и с количественными параметрами и имеющие возможность наполнения другими методами системного анализа на разных этапах исследования и принятия решений. В результате исследования была разработана система факторов для исследуемого объекта (туристско-рекреационного комплекса) и внешней для него среды, создающих изменяющиеся во времени сочетания влияний, как положительного или стимулирующего, так и отрицательного или ограничивающего характера на пути к устойчивому развитию. Полученная совокупность факторов может выступать в качестве основы для создания имитационной модели и позволяет определённым образом формализовать процесс принятия управленческих решений, основанный на сценарном моделировании. Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 18-010-00665 А/19 по теме «Методологический подход к оценке потенциала и сценарному прогнозированию развития туристско-рекреационных кластеров в условиях территориальной дифференциации».

description: Background

Posttraumatic stress disorder (PTSD) is a heterogeneous construct, and some have suggested that PTSD triggered by acute coronary syndrome (ACS) may differ from PTSD due to prototypical traumas.

Methods

We conducted the first examination of the latent structure of PTSD symptoms after suspected ACS in 399 adults in the REactions to Acute Care and Hospitalization (REACH) study, an observational cohort study of patients recruited from the emergency department during evaluation for ACS. Using confirmatory factor analysis, we compared the 4-factor dysphoria, 4-factor numbing, and 5-factor dysphoric arousal models of PTSD.

Results

Although all models fit well, the dysphoria model was selected as the best-fitting model. Further, there was measurement invariance of the dysphoria model by sex. PTSD dimensions evidenced differential associations with indicators of threat perception during ACS evaluation and adherence to cardioprotective medication.

Limitations

One limitation of this investigation is the use of self-report measures. In addition, only one-third of the sample was diagnosed with ACS at discharge; the remaining participants received diagnoses such as chest pain without a cardiac diagnosis, another symptom/disease process (e.g., hypertensive chronic kidney disease), or another cardiac disease.

Conclusions

Findings suggest that suspected ACS-related PTSD symptoms are best-represented by a 4-factor structure distinguishing between specific (e.g., re-experiencing) and non-specific (dysphoria) symptoms of PTSD that has received support in the broader PTSD literature.
