description: Предметная область данного исследования – религиозный православный туризм и современные тренды развития его направлений в российских регионах и за рубежом. Гипотеза исследования базировалась на предположении, что за период нескольких последних десятилетий развития религиозного туризма в России его структура оформилась и серьезно усложнилась. Понимание специфики и сущностных особенностей видов религиозного туризма необходимо для реализации развития данного направления на региональном и национальном уровнях. Исследование построено на основании сравнительного анализа содержания отечественных и зарубежных источников, освящающих проблемы данной отрасли рекреационного хозяйства. Помимо этого, осуществлялись сбор и обработка эмпирических данных, полученных автором в ходе личного участия в многочисленных маршрутах религиозной тематики за 10-летний период. В результате представлена авторская трактовка основных научных дефиниций, на которых базируется предметная область изучения религиозного туризма, выявлены новые ветви развития внутри паломнического и экскурсионного познавательного направлений, раскрыта их суть и обозначены перспективы развития на региональном уровне. К новым разделам религиозного туризма автор предлагает отнести религиозно-календарные и событийные виды паломничества, а также трудничество как разновидность выделенного ранее духовно-паломнического туризма. Кроме того, уделено внимание научному туризму религиозной направленности, суть которого ранее в научных работах не раскрывалась, а представление о котором сводилось к редким упоминаниям. Результаты данного исследования могут быть использованы в планировании реализации направлений развития религиозного туризма на региональном уровне при учете, что регион обладает достаточным историко-культурным и инфраструктурным потенциалом для осуществления хозяйственной деятельности в данном направлении.

description: Research on nonaqueous microemulsions containing ionic liquids as polar and/or apolar phase, respectively, is growing at a fast rate. One key property of ionic liquids that highlights their potential and their diversification compared to water is their wide liquid temperature range. In this emerging-area review article we survey recent developments in the field of nonaqueous micellar solutions and microemulsions containing ionic liquids in general with a strong emphasis on the effect of temperature in particular. Various systems are discussed and compared to their aqueous counterparts.
Gender influences in conference participation

description: In 2012 Lynne Isbell and her colleagues published a fascinating paper looking at the role of gender in conference proceedings among primatology meetings. In it they found that male organized symposia had half the number of female participants than those organized by women or both men and women. This was particularly interesting because primatology is a discipline where women have the numerical majority.

To say this opened up a can of worms would be an understatement. It provided a great mechanism for discussion on twitter and in the blogosphere (for good write ups of the original paper check here, here and here and of gender representation in geosciences here).  A positive outcome of these discussions was that Jacqueline Gill (soon to be at U of Maine), Karen Lips (U of Maryland) and Mollie Thurman (here at Columbia) and I have decided to do a similar analysis at data from the Ecological Society of America,  American Society of Ichthyologists and Herpetologists and the Society for Conservation Biology.

description: We investigate the spin-orbit (SO) interaction in two-dimensional electron gases in quantum wells with two subbands. From the 8×8 Kane model, we derive a new intersubband-induced SO term which resembles the functional form of the Rashba SO but is nonzero even in symmetric structures. This follows from the distinct parity of the confined states (even or odd) which obliterates the need for asymmetric potentials. We self-consistently calculate the new SO coupling strength for realistic wells and find it comparable to the usual Rashba constant. Our new SO term gives rise to a nonzero ballistic spin-Hall conductivity, which changes sign as a function of the Fermi energy (εF) and can induce an unusual Zitterbewegung with cycloidal trajectories without magnetic fields.

description: I have been thinking a lot about mentoring lately, I’ve started advising two undergraduate students who are starting their senior honor thesis projects.  While I am really excited about the work that these students are undertaking, I’ve been feeling a bit unprepared for class. I have had some great mentors in the past. My Ph.D. adviser was tough but encouraging, I have recently published with an additional member of my committee, and most recently my postdoc mentor went far beyond the call of duty to provide me with an intellectually stimulating and supportive environment. These men provided me with an opportunity to find my voice, and when that voice was shouting too loudly, or saying the wrong things, they constructively brought me back to the proper conversation.
Lipid membrane instability and poration driven by capacitive charging

description: A new model for the interaction of an electric pulse with a lipid membrane is proposed. Using this model we show that when a DC electric pulse is applied to an insulating lipid membrane separating fluids with different conductivities, the capacitive charging current through the membrane drives electrohydrodynamic flow that destabilizes the membrane. The instability is transient and decays as the membrane charges. The bulk conductivity mismatch plays an essential role in this instability because it results in a different rate of charge accumulation on the membrane's physical surfaces. Shearing stresses created by the electric field acting on its own induced free charge are non-zero as long as the charge imbalance exists. Accordingly, the most unstable mode is related to the ratio of membrane charging time and the electrohydrodynamic time.

description: Growing up I used to watch a lot of nature documentaries. Shark Week, Nature, National Geographic, even old Mutual of Omaha Wild Kingdom, these were always on.  As I grew older I transitioned from Zoo Books and Ranger Rick to Smithsonian and Natural History magazines.  These articles were a real inspiration to me, and showed me the diversity of things one could study as a scientist.  Now that I am doing science of my own, I am excited to find ways to communicate my work to others.  While this blog serves as a way for me to share what I am doing, I have also had the good fortune to collaborate with science communicators and journalists to tell share my research in a much more professional way. For example this summer I am thrilled to be working with Helen Scales to document our expedition to Fiji. There are two main reasons why I like to collaborate with communicators. The first is that I like what I do, and hopefully without sounding egotistical, I think what I do is pretty interesting and I’d like to share my passion with others.  Secondly, and perhaps less selfishly, the state of science awareness in the United States is pretty low, and I have great admiration for people who spend their days helping to share good stories and inform people as to why science matters.
Theoretical study of interacting hole gas in p-doped bulk III-V semiconductors
Creators: name: Schliemann, John
Publisher: name: Universität Regensburg
Year: 2006
Subjects: subject: 530 Physik

description: We study the homogeneous interacting hole gas in p-doped bulk III-V semiconductors. The structure of the valence band is modeled by Luttinger’s Hamiltonian in the spherical approximation, giving rise to heavy and light hole dispersion branches, and the Coulomb repulsion is taken into account via a self-consistent Hartree-Fock treatment. As a nontrivial feature of the model, the self-consistent solutions of the Hartree-Fock equations can be found in an almost purely analytical fashion, which is not the case for other types of effective spin-orbit coupling terms. In particular, the Coulomb interaction renormalizes the Fermi wave numbers for heavy and light holes. As a consequence, the ground state energy found in the self-consistent Hartree-Fock approach and the result from lowest-order perturbation theory do not agree. We discuss the consequences of our observations for ferromagnetic semiconductors, and for the possible observation of the spin Hall effect in bulk p-doped semiconductors. Finally, we also investigate elementary properties of the dielectric function in such systems.

description: Let $V$ be a quasi-projective algebraic variety over a non-archimedean valued field. We introduce topological methods into the model theory of valued fields, define an analogue $\hat {V}$ of the Berkovich analytification $V^{an}$ of $V$, and deduce several new results on Berkovich spaces from it. In particular we show that $V^{an}$ retracts to a finite simplicial complex and is locally contractible, without any smoothness assumption on $V$. When $V$ varies in an algebraic family, we show that the homotopy type of $V^{an}$ takes only a finite number of values. The space $\hat {V}$ is obtained by defining a topology on the pro-definable set of stably dominated types on $V$. The key result is the construction of a pro-definable strong retraction of $\hat {V}$ to an o-minimal subspace, the skeleton, definably homeomorphic to a space definable over the value group with its piecewise linear structure.

Today we are going to meet to discuss this year’s Ph.D. applicants.  While the particulars are confidential I would like to take this opportunity to talk about what I thought made a strong application.  This will be the first time being on the other side of that closed door, and I know that while I was going through the Ph.D. application process the internal decisions seemed at best byzantine and at worst as if they were unknowable.  I’m hoping that anyone going through, or better about to go through, this process may find some useful advice.  Keep in mind however that this is a N=1 situation and your mileage may vary.

description: Cynara cardunculus subsp. cardunculus, belonging to Asteraceae family, and widely distributed in the Mediterranean area, exhibits high nutraceutical and nutritional potential, as compared to the cultivated varieties. This work reports, for the first time, on genetic and metabolic characteristics of three natural populations of C. cardunculus present in the Pollino National Park (Calabria, Italy), referred to as wild cardoons, collected in different areas (Castrovillari, Trebisacce and Sibari). One wild and one cultivated sardinian genotypes were also analysed as comparison. Six nuSSRs markers, were used to assess population structure and diversity. The obtained results showed that all three populations genetically diverge from the cultivated one and cluster with sardinian wild populations. Moreover, PCoA and Bayesian clustering analyses evidenced that Trebisacce and Sibari populations were closer to each other compared to Castrovillari one. HPLC analysis, also revealed a metabolic profile particularly rich in phenolic acids for Sibari population which also exhibited the highest capacity to protect linoleic acid from peroxidation. To long-term, these results could be useful to preserve biodiversity and promote ecotypes with major nutraceutical proprieties.

This theory could be a candidate of the gauge theory with conformal fixed point. By using Wilson/Polyakov loop in a finite volume with twisted boundary conditions, we study the renormalization group flow of the gauge coupling constant. Our calculation gives consistent result with the perturbative prediction of the running coupling in the weak coupling region. We investigate a possible signal for conformal behavior in the strong coupling region.

description: In current literature, there is little congruence on an inclusive definition of human asexuality. This study explored individuals’ self-identification with asexuality as well as their conceptualization of that identity via thematic analysis. Using a Qualtrics XM survey, 374 individuals (18+ years old) answer questions regarding their experience as a person identifying themselves as asexual. Identity label authenticity, perceived impact of compulsory heterosexuality and heteronormativity on participants' current identity within the asexual spectrum, and prescribed heteronormative ideals were correlated. Thematic analysis revealed themes such as confusion about identity membership, feeling abnormal, the burden of living in a heteronormative society, and identity confidence. Participants described diverse experiences with asexuality, underscoring the necessity of establishing inclusive understandings of asexuality and its sub-identities such as demisexuality and grey/graysexuality.

description: Walls represent globally distributed, locally extensive, artificial ecosystems. Wall vegetation is still poorly known in the Mediterranean and Temperate regions of southeastern Europe. The aim of this study is to classify and describe chasmophytic vegetation of walls, covering southeastern Europe from Slovenia to North Macedonia. From a total 463 phytosociological relevés, we identify and describe 12 distinct species – poor to moderately rich vegetation units using TWINSPAN evaluated by NMDS, and indicator values. The vegetation units are included within three alliances from two macroclimate regions: (1) vegetation of cool-temperate Europe of the Cymbalario-Asplenion alliance, and (2) Mediterranean vegetation of the Galio valantiae-Parietarion judaicae and Artemisio arborescentis-Capparidion spinosae alliances. The southernmost limit of the Cymbalario-Asplenion was determined in Central Bosnia. The presence of the Artemisio arborescentis-Capparidion spinosae in the eastern Adriatic is highlighted.

description: With the recent discovery of very long hole spin decoherence times in GaAs/AlGaAs heterostructures of more than 70 ns in two-dimensional hole systems, using the hole spin as a viable alternative to electron spins in spintronic applications seems possible. Furthermore, as the hyperfine interaction with the nuclear spins is likely to be the limiting factor for electron spin lifetimes in zero dimensions, holes with their suppressed Fermi contact hyperfine interaction due to their p-like nature should be able to show even longer lifetimes than electrons. For spintronic applications, electric-field control of hole spin dynamics is desirable. Here, we report on time-resolved Kerr rotation and resonant spin amplification measurements on a two-dimensional hole system in a p-doped GaAs/AlGaAs heterostructure. Via a semitransparent gate, we tune the charge density within the sample. We are able to observe a change in the hole g factor, as well as in the hole spin dephasing time at high magnetic fields.

description: Spins in semiconductor structures may allow for the realization of scalable quantum bit arrays, an essential component for quantum computation schemes. Specifically, hole spins may be more suited for this purpose than electron spins, due to their strongly reduced interaction with lattice nuclei, which limits spin coherence for electrons in quantum dots. Here, we present resonant spin amplification (RSA) measurements, performed on a p-modulation doped GaAs-based quantum well at temperatures below 500 mK. The RSA traces have a peculiar, butterfly-like shape, which stems from the initialization of a resident hole spin polarization by optical orientation. The combined dynamics of the optically oriented electron and hole spins are well-described by a rate equation model, and by comparison of experiment and model, hole spin dephasing times of more than 70 ns are extracted from the measured data.

description: High-mobility two-dimensional electron systems may be one of the bases of future spintronic devices, where the spin states of ballistic electrons could be manipulated via external gate voltages and the resulting spin-orbit fields. Therefore, the knowledge of spin dynamics in such systems is of technical interest and offers on the other side an exciting view on the underlying physics. Here, we present time-resolved Faraday rotation measurements in a high-mobility two-dimensional electron system in a GaAs/AlGaAs quantum well structure grown along the [001] direction. Even without applied external magnetic fields the optically generated spin ensemble shows a coherent precession about the effective spin-orbit field. If a nonquantizing magnetic field is applied normal to the sample plane, the effective spin-orbit fields are rotated by the cyclotron motion of the electrons. This rotation leads to fast oscillations in the spin polarization about a nonzero value and an strong increase of the spin dephasing times. The measurement data is in excellent agreement with a model based on a kinetic equation approach.

Disconnected insertions are evaluated using the Z(4) stochastic method, along with unbiased subtractions from the hopping parameter expansion. We find that increasing the number of nucleon sources for each configuration improves the signal significantly. We obtain Gs M(0) = −0.017(25)(07), which is consistent with experimental values, and has an order of magnitude smaller error. Preliminary results for the strangeness contribution to the second moment of the parton distribution function are also presented.

Cross-cultural equivalence of Beck Depression Inventory-II (BDI-II) for Pakistani Canadian immigrants and others
Creators: name: Waseem, Rida
Publisher: name: University of British Columbia
Year: 2017

description: The purpose of the study was to demonstrate the measurement equivalence of one of the most widely used depression measures, the Beck Depression Inventory-II (BDI-II) for the Canadian Pakistani immigrants and other Canadians. The data were collected from 400 university students in the Greater Toronto Area (GTA). To examine the measurement equivalence of the BDI-II, the data were analyzed using a multi-group confirmatory factor analysis (MG-CFA) and differential item functioning (DIF) analysis. The results of MG-CFA showed evidence of configural and metric invariance, however, no sufficient evidence for scalar invariance was found. The DIF analysis identified differential response patterns in three items for the two comparison groups. The expert reviews of items provided potential sources of inequivalence. The CFA, DIF analysis and expert reviews jointly provided evidence of inequivalence which suggests, caution should be taken when comparing depressive symptoms for Pakistani to non-Pakistani populations in Canada based on BDI-II. The results from the study are expected to help researchers in modifying and developing new measures for Pakistani or other South Asian ethnic groups.

description: Lettuce, Lactuca sativa, is one of the main leafy vegetable crops, interesting as a source of phytonutrients. It is extensively studied for biotechnological applications based on in vitro regeneration. However, in lettuce, histological studies of adventitious morphogenesis during the regeneration process are lacking. Analogously, the genes involved in the initiation of adventitious shoots or embryos are unknown. Here, we used cotyledon explants of a cos lettuce (‘Romana’) to define the histological events of in-vitro morphogenesis at different times, and to investigate the nature of the regeneration pathway. Furthermore, we isolated three homeobox genes, LsWUSCHEL1-LIKE (LsWUS1L), LsWUS2L, and LsSHOOT MERISTEMLESS1-LIKE (LsSTM1L), to evaluate their transcription activity during the ontogenesis of the adventitious structures. De novo morphogenesis quickly proceeded through embryogenic and organogenic pathways, with some developmental abnormalities. The expression of LsWUS1L gradually increased during the in vitro culture of cotyledon explants. Remarkably, we detected high expression of both LsWUS2L and LsSTM1L genes after four days of culture, when the very early stages of morphogenesis were only noticeable through histological analysis. These findings suggest a key role of these genes in the rapid recruitment of the founder cells of adventitious structures.

description: Purpose: Commonly IMAT treatment plans for clinical use can only be generated by forward planning. We present a quasi-IMAT technique, simulated by step-and-shoot treatment. The purpose of this study is to investigate, if the plan quality can be improved by increasing the number of beams, keeping the number of segments constant. Materials and Methods: Quasi-IMAT plans with 18 and 36 equidistant beams were generated and the total number of segments was reduced to 36. In a second step the number of segments was increased to 72, in order to investigate if the quality of the plans as determined by DVHs of PTV and OAR improves with the number of segments. A conventional six-field IMRT plan was used as a reference. The beam setups were applied to the Carpet Phantom and to five prostate cancer patients. The plans were optimized with Oncentra Masterplan (version 3.0, DSS) for 15 MV photons and a MLC with 1 cm leaf width at isocenter. After optimization plans were normalized to the average of the PTV. For evaluation, DVHs for the plans with 18 and 36 beams were compared to the reference six-field IMRT plan. Results: In the phantom case with the very concave PTV the percentage of the volume of the OAR that receives more than 70 % of the prescribed dose were 60.7%, 31.0% and 21.7% (for the 6, 18 and 36 beams plans with 36 segments). For the prostate cases, adequate dose coverage and dose homogeneity where acomplished inside the PTV. The average percentage of dose received by 50% of the rectum volume was reduced from 45% to 41,7% (6 and 36 fields with 36 segments). Only a slight improvement in OAR sparing was observed by increasing the number of segments. In all cases the dose received by the OARs was reduced by increasing the number of beams. This effect is more pronounced in the phantom, because the target is more concave. Simultaneously the coverage and dose homogeneity of the target is unaffected. Conclusions: The advantage of quasi-IMAT technique is that it can be realized with a standard IMRT treatment planning system and a standard linac equipment. No special arc sequencing (Shepard et al., 2007) and dynamic leaf control is necessary. The plan quality is high even with a single gantry arc. Acknowledgement: This work was supported by Elekta

On Sexual Assault and Invisibility

description: This past week I had the good fortune to read an advanced copy of a powerful book Fault Line by my good friend Christa Desir.  Fault line tells a story about a young woman who was raped and how that act of violence shatters her and how that shattering reverberates among the people who care about her.  I’m not going to give the whole story away now (it goes on sale on October 15th  (you can purchase it  here), however I want to say two things about it.  First this book really shook me. I want you all to get it because this is the kind of book that makes you want to talk to people you love after reading it. It is a difficult book to read, but then again many important things are often difficult. The second aspect of the book that struck me was that the woman who was raped went into a spiral of self-destructive behavior because she wanted to be able to feel something, even if that something was negative.  She did not seek help because of multiple reasons and that ultimately lead to some difficult situations.  Seeking help is important and we should be working as a society to lower barriers for victims of sexual assault to get that help.

description: A brief review on major advances in heavy fermion physics is presented including the Ce metal phase diagram, the huge effective mass detected in CeAl3, and the successive discoveries of unconventional superconductivity in CeCu2Si2 and three U based compounds, UBe13, UPt3 and URu2Si2. In order to track the origin of the huge effective mass, the case of intermediate valence compounds is discussed with emphasis of the differences between Yb and Ce materials. The formation of the effective mass is analyzed by two regular- and singular-part contributions. Examples are given for both, antiferromagnetic (CeRu2Si2 series) and ferromagnetic tricriticalities (UGe2). Pressure and magnetic-field studies on the ferromagnetic superconductor URhGe illustrate the role of the singular effective mass enhancement on the superconducting pairing. The discovery of the Ce-115 material gives the opportunity to study deeply the interplay of antiferromagnetism and superconductivity. This is clearly demonstrated by field re-entrance AF inside the SC phase just below the superconducting upper critical field (Hc2) for CeCoIn5 or on both side of Hc2 within a restricted pressure window for CeRhIn5. The present status of the search for the hidden-order parameter of URu2Si2 is given and we emphasize that it may correspond to a lattice unit-cell doubling which leads to a drastic change in the band structure and spin dynamic, with the possibility of competition between multipolar ordering and antiferromagnetism.

The double majority rule : estimating the impact of a supermajoritarian rule in pre-Confederation Canada
Creators: name: Raddatz, Adrian
Publisher: name: University of British Columbia
Year: 2017

description: This thesis uses a counterfactual simulation to estimate the impact that applying the double majority rule would have had on legislative productivity in the Province of Canada, 1840-1867. The double majority rule was supermajoritarian in nature, and if applied would have required two sectional majorities from the administrative regions within the province to pass legislation. The thesis compares a constructed dataset where votes could only pass with a double majority to the observed data, arguing that applying the double majority rule would have reduced legislative productivity. There is weak statistical evidence found supporting gridlock interval size as the causal explanation for the decreased productivity, but this is argued to be due to abnormal status quo points and the potential for voting patterns to collapse from two ideological dimensions to one. Finally, the introduction of responsible government is found to not influence whether votes were passed with a double majority. This is explained through the partisan capacity hypothesis, which argues that supermajoritarian rules are ignored when they would prevent a government from implementing its legislative agenda. These conclusions argue that the historical literature was correct that applying the double majority rule would have reduced productivity, but wrong about the impact of responsible government on passing votes with double majorities.

description: В статье рассматривается проблемы трансграничных территорий Юго-восточной провинции Китая и Юго-запада Приморского края с позиций устойчивости. Рассмотрены природные и туристические ресурсы граничащих провинций Китая и России, развитость инфраструктуры двух стран. Основной проблемой неустойчивого, неравномерного развития туризма таких дестинаций авторы считают диспропорциональность размещения транспортных и гостиничных инфраструктур, жесткий пограничный контроль, слабое благоустройство пунктов пропуска на границе. Рассматривая туризм как одну из быстро развивающихся отраслей в современном мире, авторы прогнозируют увеличение турпотоков именно в приграничных областях. Это увеличит глобальный экономический рост туристических стран-лидеров турбизнеса. Как отрасль экономики, туризм может иметь противоположные экологические последствия, которые зависят от выбора пути развития. Разрушение может быть вызвано нерегулируемой туристской деятельностью, инфраструктурным строительством, снижением рекреационного потенциала. Возобновление определяется таким управлением окружающей средой, которое приводит к повышению рекреационной ценности, направленной на минимизацию рекреационной нагрузки, озеленение, перераспределение турпотоков, сохранение природных объектов, что делает модели природопользования устойчивым, конструктивным. Проведенный авторами анализ турпотоков соседствующих регионов Китая и России показывает тенденции к взаимному увеличению как числа посещений китайских туристов России, так и встречного турпотока из России в Китай. Выводы подтверждены анализом инфраструктуры и турпотоков граничащих дестинаций.

description: One of the things I am really enjoying about this semester is teaching my graduate seminar in conservation biology. It has been fun going back and reading the classics and also expanding out into the newer literature.  Since I am also teaching a class in marine conservation I am trying to pay special attention to non-marine topics for regular flavor conservation biology
There are few topics I consider more ‘non-marine’ than fire ecology, and this recent paper by Trauernicht et al. in Ecology and Evolution does a great job of looking at a conservation issue with multiple moving points.  In this paper “Cultural legacies, fire ecology, and environmental change in the Stone Country of Arnhem Land and Kakadu National Park, Australia” they look at the interactions between (pay attention now) Aboriginal cultural practices including both 1) fire management via prescribed burning and 2) incorporation of Water Buffalo (Bubalus bubalis) and 3) Australian government prescribed fire management across two areas.  Get all that? Right, it’s a complex story.

description: Service-oriented architectures are widely discussed as a design principle for application and enterprise architectures. Nevertheless, an adequate granularity of services has not yet been researched sufficiently from an economic perspective. The finer the granularity to realize the functions of a process, the higher the number of services is, and the more effort has to be directed towards composing them. In contrast, very coarse grained services bear the disadvantages of higher implementation costs and lower reuse potential (e.g., in different processes). The aim of the decision model proposed in this paper is to determine an adequate granularity of services from an economical perspective. Thus, degrees of freedom, which often exist for the choice of granularity after a domain analysis, can be leveraged to realize a cost-efficient solution. We illustrate the applicability and practical benefits of the decision model with an example from the context of a financial services provider.
