description: Abstract words refer to things and entities in the world that cannot be directly experienced through our senses (e.g., truth, morality). How we learn, represent, and use abstract words is one of the deepest problems in cognitive science today. I investigated this question in two experiments. In Experiment 1, I examined the effects of six semantic richness variables (sensory experience, valence, number of associates, context availability, arousal, semantic neighbourhood, and number of associates) on lexical-semantic processing for 207 abstract nouns. Behavioural tasks were lexical decision (LDT) and semantic categorization (SCT). Results showed that participants were faster to respond in LDT to words high in context availability, and faster to respond in SCT to words high in valence and sensory experience. These results suggest that abstract meanings might be grounded in our experiences with situational contexts and our bodily experiences. To further assess the extent of grounding for abstract word meanings (Experiment 2), I tested thirty-one pairs of undergraduate students in a variation of the Taboo task, in which participants communicated the meaning of the “secret” word (10 concrete, e.g., insect; 20 abstract nouns, e.g., impulse) to a partner in 1 minute or less. Analysis of verbal and gestural data yielded a number of important insights. Most notably, on a majority of trials, participants activated their partner’s concept of self or other (“You”, “Dalai Lama”), then placed that self into a situational context (“in class”) and then described the mental states, feelings, goals, etc. the self may experience. This, together with the results of my quantitative data analyses, suggests extensive recruitment of information derived from our experiences with the social and physical world and that such information is an important aspect of what we know about abstract words.

description: Automatic temporal ordering of events described in discourse has been of great interest in recent years. Event orderings are conveyed in text via va rious linguistic mechanisms including the use of expressions such as "before", "after" or "during" that explicitly assert a temporal relation -- temporal signals. In this paper, we investigate the role of temporal signals in temporal relation extraction and provide a quantitative analysis of these expres sions in the TimeBank annotated corpus.

description: Despite the burgeoning research interest in single women’s lives, few studies have examined the sexual lives of midlife women who are without a committed sexual partner. What is little understood then is how midlife women who are single understand their sexuality and their sexual relationships. Adopting a social constructionist framework and a discourse analytic perspective, this study explored the accounts of 21 women who identified as “women alone,” were in “early midlife” (aged 35-50 years), and lived in cities and towns across Canada. The women were interviewed using a semi-structured format, either in person, by phone, or by Skype, and the interviews were audio-recorded and transcribed. The analysis examined the varied and contradictory discourses of heterosexuality that the participants used to account for their sexual practices and position themselves as sexual subjects. Study results suggest that cultural changes of recent decades have entailed shifts in the discursive environment beyond the cultural resources identified by Wendy Hollway in the 1980s, i.e., “male sexual drive,” “have and hold,” and “permissive sex” discourses. Women understood their sexuality in terms of a “compulsory sexuality” that is produced by the permissive sex and “sexological” discourses and constructs sex as integral to women’s lives. For single women, this means remaining sexually attractive and youthful according to the standards of the day, a subject position that is at odds with their positioning as “maturing” women. Being positioned as “celibate” or “sexually inactive” was a “troubled” identity, and the participants navigated this tension by drawing on two “emerging” discourses, “caring sex” (i.e., “good” and “fulfilling”’ sex that includes feelings and practices of care, respect, and reciprocity) and “New Age spirituality” (i.e., compatibility, intimacy, and soul mates). Together, these discourses provided a discursive space for women to account for their sexual subjectivity outside of committed romantic relationships in a way that allowed them to be both “sexual” and “moral women.” Women’s single and midlife sexual subjectivity is discussed in the context of contemporary “postfeminist discourses” that construct female sexuality as active and empowered.

description: As the scale of medical imaging trials increases, manual quality control of the enormous volume of imaging data becomes intractable and costly. Machine learning may provide solutions to reduce the challenge of these large trials through the development of computer-assisted screening tools. The objective of this dissertation was to evaluate the suitability of machine learning for solving scalability problems of manual quality control by training an automated classifier to detect simulated motion artefact on otherwise high-quality magnetic resonance images of healthy human brain. The classifier achieved high accuracy (98.5%) without any performance optimization, and, incidentally, discovered a screening error within the experiment dataset, further demonstrating the power of machine learning in this domain and encouraging further research towards computer-assisted screening tools.

description: This study examined the influence of two supervisory styles (abusive supervision and ethical leadership) on the motivation to engage in supervisor and coworker-targeted impression management. Expectancy theory was examined as a theoretical mechanism for these relationships. Data was collected from 288 working adults regarding supervision, task interdependence with coworkers, social learning behaviors, and engagement in supervisor and coworker-targeted assertive and defensive impression management strategies. Results show that the motivation and use of IM varies across targets. Results also show ethical and abusive supervision have differential direct effects on strategy use towards both supervisors and coworkers. These findings and their implications for future research are discussed.

description: The quantum Rabi model can be solved exactly by the Bargmann transformation from real coordinate to complex variable recently [Phys. Rev. Lett. \textbf{107}, 100401 (2011)]. By the extended coherent states, we recover this solution in an alternative simpler and perhaps more physical way without uses of any extra conditions, like Bargmann conditions. In the same framework, the two-photon Rabi model are solved exactly by extended squeeze states. Transcendental functions have been derived with the similar form as those in one-photon model. Both extended coherent states and squeeze states are essentially Fock states in the space of the corresponding Bogoliubov operators. The present approach could be easily extended to study the exact solvability or integrability of various spin-boson systems with multi-level, even multi-mode.

description: Background and Context:

In Switzerland, selecting and adequately using health insurance is something that individuals often struggle with. Not being able to adequately navigate the health insurance system not only impacts one's finances but also an individual's health status.
Limited understanding of the health insurance system and a lack of skills to navigate it; namely limited health insurance literacy (HIL), is associated with poor quality health insurance choices as well as inadequate healthcare utilization and access, and thus may not only bear far reaching consequences at the individual level but also at level of the healthcare system. The Swiss health insurance system is characterized by mandatory basic health insurance coverage with a relatively complex design and continuously growing costs; at the same time, it is increasingly focusing on expanding offers of consumer-directed plans and alternative models. As a result, individuals with limited HIL struggle to adequately navigate it.
Empowering citizens to make adequate and well-informed decisions relevant to their health thus becomes an imperative. This includes the appropriate selection, use, and navigation of health insurance.

Epithelial Immunomodulation by Giardia

Subjects: subject: Parasitology
subject: Giardia

subject: Neutrophils

description: Giardia duodenalis (syn. G. intestinalis, G. lamblia) is a non-invasive, protozoan parasite of the upper small intestine of animals, including humans. Despite parasite loads exceeding 106 trophozoites per cm of small intestine, the intestinal mucosa in the majority of the Giardia-infected individuals are devoid of signs of overt inflammation. Human studies also suggest Giardia infections are capable of modulating the development of diarrheal disease in their host via unknown mechanisms. The first part of this study focused on whether Giardia infections were capable of attenuating neutrophil (PMN) accumulation in different experimental models of inflammation. Accumulation of PMNs is an archetypal event during many acute intestinal inflammatory responses contributing to the development of diarrheal disease. Our findings demonstrated Giardia infections attenuate granulocyte infiltration in an experimental model of colitis, in an isolate-dependent manner. Giardia infections also decrease tissue expression of mediators associated with PMN recruitment during in vivo colitis. Similar results were observed when Giardia trophozoites were incubated ex vivo with inflamed mucosal biopsy tissues collected from the descending colon of patients with Crohn’s disease. The second part of this study focused on identifying mechanisms by which Giardia trophozoites attenuate PMN accumulation. The intestinal epithelium is a single layer of polarized cells separating the external environment from underlying host tissues. In response to pro-inflammatory stimuli, this structure releases the PMN chemokine interleukin-8 (CXCL8) that recruits PMNs to the basolateral membrane of the intestinal epithelium. We demonstrated that Giardia trophozoites attenuate CXCL8 secretion from ex vivo small intestinal mucosal biopsy tissues and in vitro Caco-2 monolayers, following administration of IL-1β or Salmonella sp.; this involved parasite-mediated degradation of CXCL8 and attenuation of CXCL8- and C5a-induced PMN chemotaxis. Genetic assemblages of Giardia capable of infecting humans contain unique cathepsin proteases and Giardia trophozoties release cathepsin proteases into supernatants. Inhibition of Giardia cathepsin B proteases prevented parasite-mediated degradation of CXCL8 and attenuation of CXCL8 and C5a-induced PMN chemotaxis. Our findings demonstrate that Giardia infections attenuate PMN accumulation in an in vivo model of colitis. Research done in vitro highlights a role for Giardia cathepsin B proteases in degrading CXCL8 and attenuating CXCL8-induced PMN chemotaxis.
The Evolution of a Pulsating Supraglacial Stream

description: Supraglacial streams are a significant part of the glacial hydrological regime and important for understanding the dynamics between glacial hydrology, glacier dynamics, and climate change. During the 2014 ablation period on Bylot Island, Nunavut, a supraglacial stream, which flowed over a 13 m high waterfall at the front of Fountain Glacier, began to pulsate. The pulsating phenomenon involved the stoppage of flow over the waterfall for 10-15 s, with a total period of 27 s. The objective of this research was to determine the factors that influenced the evolution of the supraglacial stream. Results show a change in the weather, where multiple rainfall events occurred during the second week of the study. Analysis suggests that the rainfall caused the formation of a step-pool sequence within the streambed. In conclusion, the formation of the step-pool sequence and constructive interference from changes in flow conditions caused the distinctive pulsating.

description: Heterogeneous networks are designed to increase the capacity for cellular data traffic. Self-organization is a key element of heterogeneous cellular networks. In this thesis, we present a randomized algorithm that addresses two challenges in HetNets, namely energy saving and throughput maximization, in a self-organizing manner. More specifically, the proposed algorithm seeks to maximize an objective function that balances the trade-off between the downlink bit rate of users, and the energy consumption of base stations. To achieve this goal, we deactivate under-utilized picocells to save energy, and adjust low-power Almost Blank Subframes to utilize the frequency spectrum and minimize the interference between macrocells and picocells. An important feature of our algorithm is its distributed design, which eliminates the need for a central device to coordinate the base stations. In fact, the base stations directly interact with each other in a locally defined neighborhood to drive the system toward the optimal state.

description: Abstract Shale gas is an unconventional gas source now widely in production in the Appalachian and Michigan Basins in the United States. Shale gas production in the United States has increased tremendously over the past decade and many companies are now looking to Canada to expand gas production from shale gas sources in the Western Canadian Sedimentary Basin (WCSB). Natural gas is a favourable alternative fuel to other hydrocarbons because it results in lower greenhouse gas and carbon emissions. In North America there are several shale gas plays yet the potential for shale gas systems within Canada is still being evaluated. As conventional natural gas production in Canada declines shale gas may offset this decline in Canada. The WCSB contains over 1,000 Tcf of gas in its shale deposits thus the prize is significant. The research documented in this thesis focuses on understanding methane gas transport and generation mechanisms, identifying the microorganisms present in shale gas systems, determining how to quantify and model biogenic gas production rates, and determining how to enhance biogenic gas rates by substrate addition. In the near future as technology and research develops, methanogenesis may be a significant and sustainable source of natural gas production in shallow reservoirs. The key outcomes of the proposed research are to quantify the amount of biogenic gas produced in shallow shale reservoirs using a new gas material balance theory, reactive engineering modelling, and numerical reservoir simulation. Additionally, methane production rates were determined within the laboratory using produced water and core samples from shallow shale gas wells and the microorganisms that produce methane gas within the reservoir were identified at the family level.

description: The research in this paper consists of three essays 1. Financial Structure and Economic Growth 2. Oil Price Uncertainty and Industrial Production, and 3. Money, Velocity, and the Stock Market. In the rst essay, we use Bayesian classi cation and nite mixture models to extract information from Levine 's (2002) cross-country database and reconsider the relationship between nancial structure and long-run economic growth. Our methods, based on statistical similarities and multi-dimensional structures, al- low for parameter heterogeneity across the countries in Levine s database and yield substantially di¤erent ndings than Levine s regarding the relationship between nancial structure and economic performance. In the second essay, we estimate a bivariate GARCH-in-Mean VAR with a BEKK variance speci cation, to investigate whether oil price volatility a¤ects real economic activity. We use the same data set of thirty-seven, aggregate and disaggregate, industrial production indices used by Herrera et al. (2011) as a proxy for real output and a post-1973 data sample. We check the robustness of our results by using two proxies for the price of oil, the West Texas Intermediate (WTI) oil price and the Re ners Acquisition Cost (RAC) of crude oil, and by testing for both nominal and real e¤ects. We nd signi cant evidence of non-lin- earities for both aggregate and disaggregate indices. Our research highlights the importance of nominal prices and extreme events such as the Great Contraction in the transmission of nonlinearities. In our third essay, we provide a study of the relationship between money growth variability, velocity, and the stock market using recent advances in nancial econometrics. We estimate a trivariate VARMA, GARCH-in-Mean, BEKK model to quantify the e¤ects of nancial market and money supply instability. We investigate the robustness of the results to di¤erent de nitions of money using monthly Divisia indices for the United States from the Center for Financial Stability (CFS). Empirical evidence supports signi cance of nancial market and money supply volatility, and we conclude that Friedman s money supply volatility hypothesis is alive and well. 1
Particle acceleration by circularly and elliptically polarised dispersive Alfven waves in a transversely inhomogeneous plasma in the inertial and kinetic regimes

description: Dispersive Alfven waves (DAWs) offer, an alternative to magnetic reconnection, opportunity to accelerate solar flare particles. We study the effect of DAW polarisation, L-, R-, circular and elliptical, in different regimes inertial and kinetic on the efficiency of particle acceleration. We use 2.5D PIC simulations to study how particles are accelerated when DAW, triggered by a solar flare, propagates in transversely inhomogeneous plasma that mimics solar coronal loop. (i) In inertial regime, fraction of accelerated electrons (along the magnetic field), in density gradient regions is ~20% by the time when DAW develops 3 wavelengths and is increasing to ~30% by the time DAW develops 13 wavelengths. In all considered cases ions are heated in transverse to the magnetic field direction and fraction of the heated particles is ~35%. (ii) The case of R-circular, L- and R- elliptical polarisation DAWs, with the electric field in the non-ignorable transverse direction exceeding several times that of in the ignorable direction, produce more pronounced parallel electron beams and transverse ion beams in the ignorable direction. In the inertial regime such polarisations yield the fraction of accelerated electrons ~20%. In the kinetic regime this increases to ~35%. (iii) The parallel electric field that is generated in the density inhomogeneity regions is independent of m_i/m_e and exceeds the Dreicer value by 8 orders of magnitude. (iv) Electron beam velocity has the phase velocity of the DAW. Thus electron acceleration is via Landau damping of DAWs. For the Alfven speeds of 0.3c the considered mechanism can accelerate electrons to energies circa 20 keV. (v) The increase of mass ratio from m_i/m_e=16 to 73.44 increases the fraction of accelerated electrons from 20% to 30-35% (depending on DAW polarisation). For the mass ratio m_i/m_e=1836 the fraction of accelerated electrons would be >35%.

description: We numerically study the quantum walk search algorithm of Shenvi, Kempe and Whaley [PRA \textbf{67} 052307] and the factors which affect its efficiency in finding an individual state from an unsorted set. Previous work has focused purely on the effects of the dimensionality of the dataset to be searched. Here, we consider the effects of interpolating between dimensions, connectivity of the dataset, and the possibility of disorder in the underlying substrate: all these factors affect the efficiency of the search algorithm. We show that, as well as the strong dependence on the spatial dimension of the structure to be searched, there are also secondary dependencies on the connectivity and symmetry of the lattice, with greater connectivity providing a more efficient algorithm. In addition, we also show that the algorithm can tolerate a non-trivial level of disorder in the underlying substrate.

description: Using results from field experiments and forward modelling, factors affecting the orientation calibration of borehole geophones were investigated. Well deviation, lateral raybending and anisotropy were all found to produce systematic deviations in orientation analysis. A method was developed to compensate for effects due to a deviated well, and successfully applied to a field dataset. The effects due to lateral raybending and anisotropy were characterised using analytic and finite-difference models; these produced one-cycle and two-cycle sinusoidal trends when orientation was plotted against source-well azimuth. Significant evidence of these trends was found in field examples, in that the magnitude of the trends was greater than the standard deviations in orientation azimuth. Analytic and hodogram methods of orientation analysis were compared, and it was found that the analytic method produced more consistent results. The optimal size of the analysis window was related to the wavelength of the direct P-wave arrival, but should generally be determined experimentally. Finally, it was shown that the optimal source-well offset range for calibration surveys was between 1 and 2 times the receiver depth.
Risk Management Process for Managing the Additional Risks Associated with Fast Tracking Engineering Phase of Oilsands Megaprojects in Alberta

description: Megaprojects are large-scale complex ventures that typically attract a high level of public attention. They are inherently risky due to the long duration and many complex interfaces associated with the industry and the execution environment. It is common to fast track this type of projects by overlapping phases and activities for business reasons. The compressed project schedule introduces additional risks to these megaprojects. To manage these additional risks, corporations are using a project risk management process, typically based on the Project Management Institute (PMI) methodology. The selective literature review in this research shows that different project risk management processes have similar components: risk strategy, risk identification, risk analysis, risk response and risk control. However, the poor performance of some aspects of project management in megaprojects indicates that these processes are not always successful in managing risks, and this research is designed to find out why. The researcher studied eight projects by interviewing industry practitioners in the Alberta oil sands to find out what aspect of the project risk management process does not work in the megaproject environment. Then the researcher conducted an online survey to verify the findings. The answers are synthesized resulting in the identification of four interconnected factors: Human Factors, Efficiency Factors, Integration Factors and Organization Factors. To ensure the internal validity of the research study, the triangulation strategy is used. To externally validate the research finding, the opinion of an expert panel is acquired. The research finding will enhance the PMI project risk management process and make it more applicable to the megaproject environment. The researcher proposes improvement to the PMI project risk management process by adding a few steps to emphasize on the areas that are often overlooked, enhancing the collaborative partnership in execution phase of the project by using an integrator entity, and a guideline consisting of the best practices to create a framework for managing risks in fast tracked major projects. The findings of this research will assist the researchers in optimizing the PMI project risk management process for fast tracking megaprojects and industry practitioners in effective project risk management in megaproject environment.

description: We show that submicron Silicon spheres, whose polarizabilities are completely given by their two first Mie coefficients, are an excellent laboratory to test effects of both angle-suppressed and resonant differential scattering cross sections. Specifically, outstanding scattering angular distributions, with zero forward or backward scattered intensity, (i.e., the so-called Kerker's conditions), previously discussed for hypothetical magnetodielectric particles, are now observed for those Si objects in the near infrared. Interesting new consequences for the corresponding optical forces are derived from the interplay, both in and out resonance, between the electric and magnetic induced dipoles.
Expert witnesses : why the Evangelical Fellowship of Canada selects legal mobilization
Creators: name: Nikkel, Joel David
Publisher: name: University of British Columbia
Year: 2010

description: Two recent areas of controversy include the "legalization" and the "evangelical-ization" of Canadian politics. The paper connects these two areas of controversy by examining why Canada’s largest evangelical interest group, the Evangelical Fellowship of Canada (EFC), has emerged as a frequent intervener in Canada's courts. In order to answer this question, the paper combines an analysis of the interveners at the Supreme Court 1985-2009 with a descriptive analysis of the EFC’s selection of legal mobilization that relies upon elite interviews, EFC publications, and public documents. The paper then tests the dominant explanations for interest group legal engagement (articulated as four hypotheses) against the EFC's experience. The paper shows that the EFC's selection of judicial engagement is not determined by their legal resources, the opening of political opportunities, or normative commitments to judicial review; but rather, by an “awakening” to the increased salience of the courts as a policy arena. Because of the EFC's ambivalence regarding the normative place of the judiciary in Canadian political life, I term their attitude "judicial realism". As a result of this perception, the EFC adds legal engagement to their other lobbying strategies. In order to be where important decisions are made, the EFC mobilizes in the courts. Because of this attitude towards judicial power, the evidence suggests that the EFC will continue to select legal engagement regardless of any advantages they may accrue in other lobbying arenas.

description: The United Nations and the World Health Organization recognized domestic violence as the most severe form of gender-based violence. While men are the primary perpetrators of sexual abuse and domestic violence causing injury and death, preventing domestic violence is commonly viewed as a woman’s issue. Research emphasizes that socialization towards male dominance in both public and private spheres and intergenerational patterns of abuse contribute to intimate partner violence. A growing body of literature also suggests that domestic violence can be influenced by colonization; racism; migration and resettlement; and class/poverty, among other forms of structural inequality. Within the last two decades, there has been an increase in the number of initiatives by men to address domestic violence; however, research in this area is limited. In particular, there is a need for Canadian studies on promising approaches to engaging men in violence prevention that incorporate Canada’s multicultural and Indigenous contexts. This dissertation used a feminist participatory action research framework grounded in an intersectionality analysis to engage 20 community men and five women violence prevention leaders in Calgary, Alberta, Canada. Through this work, a collective-cultures theoretical/practice model was developed that reflects a multi-layered and multi-faceted approach to domestic violence prevention. This model and other collective knowledge from the study were used to promote men’s leadership roles and address domestic violence from an intersectional lens. The emergence of a male-led violence prevention group, Men’s Action Network Calgary, was an important outcome of the research. This study contributes to the exploration of new and potentially innovative ways to prevent domestic violence and reduce its impact.
The Idea of a Post Colonial University

description: Universities in the English-speaking world may trace their origins to England, where the first universities of Oxford and Cambridge were established. These universities were, for centuries, the models for universities to come both in terms of structure and philosophy; and they also became a tool of British colonial policy. With the progression of British expansionism, many English men penned their ideas of a university; some of which were brought to fruition. In the 21st century, we have a multiplicity of independent nations which were formerly under British rule. While in most societies there was a phasing out of colonial institutions, many universities established during the colonial epoch seem to have withstood the test of time. It would be interesting therefore to assess some of these institutions and their evolutions in a broader endeavour to examine developments in higher education in societies post-independence. What conversations were had prior to independence regarding higher education? What ideas of a post-colonial university prevailed and what ideas should have been put forth? Were there shifts away from what constituted a colonial university? This paper is also an attempt to include universities in the post-colonial discourse and to propose an ideals of the university from a post-colonial perspective.

description: In presence of a synthetic non-Abelian gauge field that induces a Rashba like spin-orbit interaction, a collection of weakly interacting fermions undergoes a crossover from a BCS ground state to a BEC ground state when the strength of the gauge field is increased [Phys. Rev. B {\bf 84}, 014512 (2011)]. The BEC that is obtained at large gauge coupling strengths is a condensate of tightly bound bosonic fermion-pairs whose properties are solely determined by the Rashba gauge field -- hence called rashbons. In this paper, we conduct a systematic study of the properties of rashbons and their dispersion. This study reveals a new qualitative aspect of the problem of interacting fermions in non-Abelian gauge fields, i.e., that the rashbon state induced by the gauge field for small centre of mass momenta of the fermions ceases to exist when this momentum exceeds a critical value which is of the order of the gauge coupling strength. The study allows us to estimate the transition temperature of the rashbon BEC, and suggests a route to enhance the exponentially small transition temperature of the system with a fixed weak attraction to the order of the Fermi temperature by tuning the strength of the non-Abelian gauge field. The nature of the rashbon dispersion, and in particular the absence of the rashbon states at large momenta, suggests a regime of parameter space where the normal state of the system will be a dynamical mixture of uncondensed rashbons and unpaired helical fermions. Such a state should show many novel features including pseudogap physics.

description: The geopolitical rivalry between Saudi Arabia and Iran has exerted a
 profound influence on the internal dynamics of Middle Eastern nations
 since the mid-2000s, with Lebanon standing out as a significant case
 study. This doctoral thesis seeks to explore in depth the specific
 characteristics that have rendered Lebanon uniquely susceptible to
 external interference from these regional powers, particularly through
 their respective tutelary models. While existing international relations
 literature extensively covers the Saudi-Iranian rivalry in the broader
 Middle East, this thesis aims to fill a crucial gap by providing a
 detailed analysis of how these powers' distinct tutelary approaches
 manifest within Lebanon and shape its political landscape. Lebanon's
 strategic position and complex sectarian makeup have made it a
 battleground for regional influence, where Saudi Arabia and Iran compete
 not only for geopolitical supremacy but also for ideological and strategic
 footholds. This thesis posits that Lebanon's historical and
 contemporary vulnerabilities to external manipulation are rooted in a
 combination of socio-political fragmentation, historical ties to external
 powers, and the legacy of sectarianism exacerbated by regional proxy
 conflicts.
Unveiling the gas kinematics at 10 AU scales in high-mass star-forming regions (Milliarcsecond structure of 6.7 GHz methanol masers)

description: This work presents a study of the milliarcsecond structure of the 6.7 GHz methanol masers at high-velocity resolution (0.09 km s^(-1)) in four high-mass star-forming regions: G16.59-0.05, G23.01-0.41, IRAS20126+4104, and AFGL5142. We studied these sources by means of multi-epoch VLBI observations in the 22 GHz water and 6.7 GHz methanol masers, to determine the 3-D gas kinematics within a few thousand AU from the (proto)star. The present work exploits the 6.7 GHz maser data collected so far to investigate the milliarcsecond structure of this maser emission at high-velocity resolution. Most of the detected 6.7 GHz maser features present an ordered (linear, or arc-like) distribution of maser spots on the plane of the sky, together with a regular variation in the spot LSR velocity (V_LSR) with position. Typical values for the amplitude of the V_LSR gradients (defined in terms of the derivative of the spot V_LSR with position) are found to be 0.1-0.2 km s^(-1) mas^(-1). In each of the four target sources, the orientation and the amplitude of most of the feature V_LSR gradients remain remarkably stable in time, on timescales of (at least) several years. We also find that the data are consistent with having the V_LSR gradients and proper motion vectors in the same direction on the sky, considered the measurement uncertainties. The time persistency, the ordered angular and spatial distribution, and the orientation generally similar to the proper motions, altogether suggest a kinematical interpretation for the origin of the 6.7 GHz maser V_LSR gradients. This work shows that the organized motions (outflow, infall, and rotation) revealed by the (22 GHz water and 6.7 GHz methanol) masers on large scales (~100-1000 AU) also persist to very small (~10 AU) scales.

description: The application for the "Hainan Tropical Rainforest and Li Ethnic Group Traditional Settlements" World Heritage project has been officially submitted to the UNESCO World Heritage Center. These traditional settlements of the Li ethnic group are a valuable representation of early Li society and tropical island tribal settlements. Recognizing their cultural and historical significance is crucial for the declaration of the world's "double heritage" and the preservation of Li ethnic group culture.

description: Background Venues form part of the sampling frame for time-location sampling, an approach often used for HIV surveillance. While sampling location is often regarded as a nuisance factor, venues may play a central role in structuring risk networks. We investigated individual reports of risk behaviors and infections among men who have sex with men (MSM) attending different venues to examine structuring of HIV risk behaviors. However, teasing apart ‘risky people’ from ‘risky places’ is difficult, as individuals cannot be randomized to attend different venues. However, we can emulate this statistically using marginal structural models, which inversely weight individuals according to their estimated probability of attending the venue. Methods We conducted a cross-sectional survey of 609 MSM patrons of 14 bars in San Diego, California, recruited using the Priorities for Local AIDS Control Efforts (PLACE) methodology, which consists of a multi-level identification and assessment of venues for HIV risk through population surveys. Results and Discussion Venues differed by many factors, including participants’ reported age, ethnicity, number of lifetime male partners, past sexually transmitted infection (STI), and HIV status. In multivariable marginal structural models, venues demonstrated structuring of HIV+ status, past STI, and methamphetamine use, independently of individual-level characteristics. Conclusions Studies using time-location sampling should consider venue as an important covariate, and the use of marginal structural models may help to identify risky venues. This may assist in widespread, economically feasible and sustainable targeted surveillance and prevention. A more mechanistic understanding of how 'risky venues' emerge and structure risk is needed.
