PTSD and associated features as predictors of revictimization and perpetration with samples of adults abused during childhood
Creators: name: Dietrich, Anne Marie
Publisher: name: University of British Columbia
Year: 2009

description: Two-hundred and twenty-four participants who reported a history of child abuse trauma were recruited from the internet, clinical (community outpatient) and prison settings and completed a battery of assessment measures, including Briere's Child Maltreatment Interview Schedule (CMIS) (slightly modified), Detailed Assessment of Traumatic Stress (DAPS), Cognitive Distortion Scale (CDS), and Inventory of Altered Self Capacities (IASC); van der Kolk's Self Inventory of Disorders of Extreme Stress (SIDES-SR); Nijenhuis's Somatoform Dissociation Questionnaire (SDQ-20); and a modification of the CMIS to assess for adult victimization experiences (Adult Victimization Survey or AVS; Dietrich, unpublished instrument). It was hypothesized that Posttraumatic Stress Disorder (PTSD), Affect Dysregulation, and Problems with Interpersonal Relatedness would be associated with later revictimization experiences during adulthood with this sample, and that disturbances in ability to regulate self capacities and other complex posttraumatic sequelae would be associated with perpetration of physical or sexual violence during adulthood. Data were analyzed for 207 individuals who reported childhood maltreatment per the CMIS. Results provide partial support for the hypotheses. Women were significantly more likely to report revictimization, and male inmates were significantly more likely to perpetrate against others. Whereas PTSD and Somatoform Dissociation are the strongest dynamic predictors of any sexual or physical revictimization, Impaired Self Capacities are more often associated with revictimization by intimate partners in particular. Trauma-specific dissociation was associated with a decreased risk of revictimization, whereas peritraumatic and trait dissociation did not enter predictive models. Posttraumatic sequelae were not associated with increased risk of physical perpetration with these samples; however, IASC scores were associated with an increased risk of sexual perpetration and victim-based cognitive distortions were associated with decreased odds of sexual violence. These findings provide partial support for the Complex PTSD (Herman, 1992a) construct. Results are discussed in terms of implications for treatment, further study, and classification. Limitations are noted.

description: Hybrid physics-machine learning models are increasingly being used in simulations of transport processes. Many complex multiphysics systems relevant to scientific and engineering applications include multiple spatiotemporal scales and comprise a multifidelity problem sharing an interface between various formulations or heterogeneous computational entities. To this end, we present a robust hybrid analysis and modeling approach combining a physics-based full order model (FOM) and a data-driven reduced order model (ROM) to form the building blocks of an integrated approach among mixed fidelity descriptions toward predictive digital twin technologies. At the interface, we introduce a long short-term memory network to bridge these high and low-fidelity models in various forms of interfacial error correction or prolongation. The proposed interface learning approaches are tested as a new way to address ROM-FOM coupling problems solving nonlinear advection-diffusion flow situations with a bifidelity setup that captures the essence of a broad class of transport processes.

description: From the prospect of implementation of the Mercosul/UE agreement, which should allow the strengthening of the trade between the two blocks, we analyzed the possible gains in two alternative scenarios of integration using a Partial Equilibrium Model for the estimation of trade creation and trade deviation in the Brazilian Agricultural Export Sector. The results for the two levels of tariff reduction confirmed the expectations that the integration Mercosul/UE would provide significant commercial gains for the Brazilian agribusiness. In addition, the estimates of trade creation were for most of the simulations superior to those of trade deviation, confirming the productive efficiency and competitiveness of the Brazilian Agricultural Export Sector in the world economy.
Observational Constraints on the Multiphase Nature of Outflows Using Large Spectroscopic Surveys at $z\sim$0

description: Mass outflow rates and loading factors are typically used to infer the quenching potential of galactic-scale outflows. However, these generally rely on observations of a single gas phase which can severely underestimate the total ejected gas mass. To address this, we use observations of high mass ($\geqslant$10$^{10}$ M$_{\odot}$), normal star-forming galaxies at $z\sim$0 from the MaNGA, xCOLD GASS, xGASS and ALFALFA surveys and a stacking of NaD, H$α$, CO(1-0) and HI 21cm tracers with the aim of placing constraints on an average, total mass outflow rate and loading factor. We find detections of outflows in both neutral and ionised gas tracers, with no detections in stacks of molecular or atomic gas emission. Modelling of the outflow components reveals velocities of $|$v$_{\text{NaD}}|$=131 km s$^{-1}$ and $|$v$_{\text{H}α}|$=439 km s$^{-1}$ and outflow rates of $\dot{M}_{\text{NaD}}$=7.55 M$_{\odot}$yr$^{-1}$ and $\dot{M}_{\text{H}α}$=0.10 M$_{\odot}$yr$^{-1}$ for neutral and ionised gas, respectively. Assuming a molecular/atomic outflow velocity of 200 km s$^{-1}$, we derive upper limits of $\dot{M}_{\text{CO}}

description: In recent observational studies, star-forming galaxies have been shown to follow a relation often dubbed the fundamental metallicity relation (FMR). This relation links the stellar mass of a galaxy with its star formation rate (SFR) and its gas-phase metallicity. Specifically, the FMR predicts that galaxies, at a given stellar mass, exhibit lower metallicities for higher SFRs. This trend is qualitatively consistent with observations of galaxy pairs, which have been robustly shown to experience increasing gas-phase metallicity dilution and enhanced star formation activity with decreasing projected separation. In this work, we show that, despite the qualitative consistency with FMR expectations, the observed O/H dilution in galaxy pairs of the Sloan Digital Sky Survey is stronger than what is predicted by the FMR. We conclude that the evolutionary phase of galaxies interacting with companions is not encoded in the FMR, and thus, mergers constitute a clearly defined population of outliers. We find that galaxies in pairs are consistent with the FMR only when their separation is larger than 110 kpc. Finally, we also quantify the local environment of the pairs using the number of galaxy neighbours within $2\, \mathrm{Mpc}$, $N_2$, and the projected separation to the second closest galaxy, $r_2$. We find that pairs are more sensitive to a second companion than to the local galaxy density, displaying less elevated SFRs with smaller values of $r_2$.

description: If the Ehrenfest time tau_E of a ballistic cavity is not negligible in comparison to its dwell time tau_D, the weak localization correction to the cavity's transmission is suppressed proportional to exp(-tau_E/tau_D). At the same time, quantum interference enhances the probability of reflection into the mode of incidence by a factor two. This `enhanced backscattering' does not depend on the Ehrenfest time. We show that, in addition to the diagonal enhanced backscattering, there are off-diagonal contributions to coherent backscattering that become relevant if the Ehrenfest time is not negligible.

description: To ignore the historical perspective of socio-economical phenomena while looking ahead to the future in an attempt to raise expectations and set new challenges, can prove a risky move when approaching the cooperative movement as a whole. This is particularly so in the case of the European agricultural cooperatives. We expect them to play a relevant role in the overall panorama of a globalized world. The aim of this article is to trace the origins of the agricultural cooperative movement in seven European countries (Belgium, Denmark, France, Italy, The Netherlands, Portugal and the United Kingdom) and discuss the coincidences and differences which account for common problems with a view to avoiding them in future joint ventures. Some issues discussed here are, among others, the legal framework, the public institutions concerned with the promotion and development of cooperatives, promoting social groups, the underlying values involved, and finally the various types of cooperatives and the important role they play in specific economic sectors. The analysis includes a comparative synthesis as a point of departure for new challenges in the near future.

We find all the relevant modes of this theory and derive necessary conditions that these modes must satisfy in order to be stable and subluminal. With these conditions, we then derive constraints for the shear and diffusion relaxation times and the transport coefficients related to diffusion-viscous coupling.

description: Our ability to correct the observational photometry of galaxies depends upon our knowledge of the attenuation of light produced by the dust contained in the interstellar medium. We will present a model based on the statistical properties of the local density in isothermal turbulence which might be appropriate to calculate the radiative transport through the diffuse interstellar medium. The model will be applied to study the attenuation caused by a distant foreground screen and a non scattering slab where the sources are mixed within the turbulent medium. It will be shown how the turbulent structure affects the attenuation curve and how the attenuation curve varies with the thickness of a foreground screen.

description: Over the years, the unique form of cooperative settlement known as a Kibbutz, has had to undergo various difficulties and changes, yet it has managed to maintain its principles and survive. However, during the last decade, many kibbutzim have made substantial changes which contradict traditional Kibbutz ideology. This article is based on the report of the Public Committee for the kibbutzim, established in 2002 to recommend a new legal definition befitting the development that took place in the kibbutzim in the last decades. The Committee was also asked to submit its opinion on the issue of allocating apartments to kibbutz members. The article describes the inevitable changes that have occurred and analyzes the reasons and considerations that have led to the creation of a new form of Kibbutz.

It has been demonstrated that many complex networks display various synchronization phenomena. In this paper, we introduce a time-varying complex dynamical network model. We then further investigate its synchronization phenomenon and prove several network synchronization theorems. Especially, we show that synchronization of such a time-varying dynamical network is completely determined by the inner-coupling matrix, and the eigenvalues and the corresponding eigenvectors of the coupling configuration matrix of the network.

description: We present here two novel algorithms for simulated tempering simulations, which break detailed balance condition (DBC) but satisfy the skewed detailed balance to ensure invariance of the target distribution. The irreversible methods we present here are based on Gibbs sampling and concern breaking DBC at the update scheme of the temperature swaps. We utilise three systems as a test bed for our methods: an MCMC simulation on a simple system described by a 1D double well potential, the Ising model and MD simulations on Alanine pentapeptide (ALA5). The relaxation times of inverse temperature, magnetic susceptibility and energy density for the Ising model indicate clear gains in sampling efficiency over conventional Gibbs sampling techniques with DBC and also over the conventionally used simulated tempering with Metropolis-Hastings (MH) scheme. Simulations on ALA5 with large number of temperatures indicate distinct gains in mixing times for inverse temperature and consequently the energy of the system compared to conventional MH. With no additional computational overhead, our methods were found to be more efficient alternatives to conventionally used simulated tempering methods with DBC. Our algorithms should be particularly advantageous in simulations of large systems with many temperature ladders, as our algorithms showed a more favorable constant scaling in Ising spin systems as compared with both reversible and irreversible MH algorithms. In future applications, our irreversible methods can also be easily tailored to utilize a given dynamical variable other than temperature to flatten rugged free energy landscapes.
Economic analysis of anaerobic digestion in Bergen County, New Jersey
Creators: name: Dill, Alexandra
Publisher: name: No Publisher Supplied
Year: 2021

description: This study focuses on the economic feasibility of adding an anaerobic digester facility to Bergen County. Anaerobic digestion is the process when manure, wastewater biosolids, food waste, or other organic matter is fed into a reactor and is broken down in the absence of oxygen producing two main outputs: biogas and digestate. Anaerobic digestion facilities normally require a high upfront capital cost but have different sources of cost savings and revenues that can make them profitable. Five different scenarios were evaluated that differ in feedstock amounts based on residential, commercial, industrial and institutional food waste. Using these feedstock amounts, the capital costs, operating and maintenance costs, cost savings and revenues were determined. Using these costs and benefits the Net Present Value (NPV), Payback Period, and Return on Investment (ROI) were calculated. Despite the high upfront capital costs, all of the scenarios presented a positive NPV and ROI along with a payback period of around 7.5 years. This is largely the result of New Jersey specific incentives, prices and cost savings being included in the economic analysis. Although all of the scenarios generated a positive outcome, the scenario with the smallest amount of feedstock may appeal more to a private sector investor as it presented the greatest ROI and shortest payback period. On the opposite side, the public sector may lean towards the greatest amount of feedstock as it has the greatest NPV while reducing the greatest amount of greenhouse gas emissions. Overall, all of the scenarios that were evaluated would be profitable and generate a revenue stream out of food waste that would normally be sent to the landfill.

description: We present a new type of deterministic dynamical behaviour that is less predictable than white noise. We call it anti-deterministic (AD) because time series corresponding to the dynamics of such systems do not generate deterministic lines in Recurrence Plots for small thresholds. We show that although the dynamics is chaotic in the sense of exponential divergence of nearby initial conditions and although some properties of AD data are similar to white noise, the AD dynamics is in fact less predictable than noise and hence is different from pseudo-random number generators.

description: The Australian dollar is considered a commodity-based currency, with the high level of primary commodity exports in Australia’s trade balance given as an explanation. Key studies have concluded that Australia’s terms of trade are a primary driver of the real exchange rate based on a comparative advantage trade model. These studies have been undertaken at an aggregate level where changes in the terms of trade have been assumed as a given. Since the Australian economy was deregulated in the early 1980s, there have been dramatic changes in the structure of the economy. Australia’s trading activity has grown and now contributes more within the domestic economy. Similarly the structure and contribution of key imports and exports has also evolved. Furthermore the role of the traded goods and services balance and the income balance within the Australian current account balance has also changed, with a significant change occurring in 2003/04. The purpose of this paper is twofold. Firstly it establishes whether the relationship between the Australian exchange rate and terms of trade has changed in response to changes in the role of the traded goods and services sector within the Australian current account balance. Secondly the paper disaggregates the movements in the terms of trade to establish what role its various components have on the wider relationship between the Australian exchange rate and the terms of trade. The paper concludes that despite substantial changes in the structure and nature of the current account balance and the traded goods and services sector, the Australian exchange rate still responds to changes in the terms of trade as if it is still a commodity-based currency and economy.

description: The Queensland Fruit Fly (QFF) — Bactrocera tryoni — poses a significant threat to horticultural production in Victoria causing losses of fruit and jeopardising access to interstate and international markets. The Victorian Government implements and largely funds an area freedom program to manage QFF. Concern about the record number of outbreaks in 2007-08 and the escalating costs of maintaining the current management regime, led the Victorian Department of Primary Industries to review the program to identify improved strategies for managing QFF. As part of this work, a benefit cost analysis (BCA) of alternative strategies has been conducted. While the BCA method is well established, in general few studies are publicly available for area freedom programs. In this paper a number of the practical issues encountered in analysing area freedom are detailed, such as estimating welfare effects, how to consider social and environmental costs and benefits and incorporating risk for managing pests. Implications for policy and the design of future programs are discussed. The approach and issues identified in this paper provide insights for other agencies undertaking similar BCAs to inform biosecurity policy.
Characterization of an iron permease in Cryptococcus neoformans
Creators: name: Simmer, Megan Irene
Publisher: name: University of British Columbia
Year: 2009

description: Cryptococcus neoformans is an opportunistic fungal pathogen with worldwide distribution. Pathogenesis is mediated by several virulence factors including growth at 37°C, melanin synthesis and capsule formation. Expression of the thick polysaccharide capsule is stimulated under iron-limiting conditions. Analysis of SAGE libraries of cells grown under iron-replete and iron-limited conditions identified orthologs of two components of the Saccharomyces cerevisiae high affinity iron uptake system, FTR1 and FET3. These genes, encoding the high affinity iron permease (FTR1) and the multicopper oxidase (FET3), form a cluster of functionally related genes in C. neoformans. Molecular genetic techniques were used to analyze the regulation of expression of FTR1 and FET3 by iron, copper and components of the PKA pathway. The results suggest that iron starvation stimulates transcription ofFTRl and FET3 regardless of genetic background and that maintenance of basal transcription of FTR1 requires the activity of P KA catalytic subunits. Supplemental copper stimulates FET3 expression but represses FTR1 expression. The contribution oiFTRl to C. neoformans growth under iron-limited conditions and response to oxidative stress was investigated in ftrl mutants. The results suggest that FTR1 is important for growth under iron-limiting conditions and that response to oxidative stress is also iron-dependent. The high-affinity iron transport system of C. neoformans represents a key cellular strategy for acquisition of a limiting nutrient in the environment. Elucidation of the mechanisms by which C. neoformans obtains iron under iron-limited conditions aids understanding of cell growth and proliferation inside the host and its potential contribution to virulence.
Adaptation, Mitigation and “Green” R&D to Combat Global Climate Change. Insights From an Empirical Integrated Assessment Exercise

description: This work develops a framework for the analysis at the macro-level of the relationship between adaptation and mitigation policies. The FEEM-RICE growth model with stock pollution, endogenous R&D investment and emission abatement is enriched with a planned-adaptation module where a defensive capital stock is built through adaptation investment. Within this framework the optimal path of planned adaptation, the optimal inter and intra temporal mix between adaptation, mitigation and investment in R&D, and the sensitivity of a strategy to each other is identified. The major conclusions of this research show that adaptation, mitigation and R&D are strategic complements as all concur together to the solution of the climate change problem; nonetheless the possibility to adapt reduces the need to mitigate and partly crowds out other forms of investment like those in R&D. The optimal intertemporal distribution of strategies is also described: it requires to anticipate mitigation effort that should start already when climate damages are low and postpone adaptation intervention until they are substantial. Thus the possibility to adapt is not a justification to delay abatement activities. A sensitivity analysis demonstrates the robustness of these results to different parameterizations, in particular to changes in expected climate-change damages and in the discount rates.

description: A galaxy-galaxy merger and the subsequent triggering of starburst activity are fundamental processes linked to the morphological transformation of galaxies and the evolution of star formation across the history of the Universe. Both nuclear and disk-wide starbursts are assumed to occur during the merger process. However, quantifying both nuclear and disk-wide star formation activity is non-trivial because the nuclear starburst is dusty in the most active merging starburst galaxies. This paper presents a new approach to this problem: combining hydrogen recombination lines in optical, millimeter, and free-free emission. Using NGC~3256 as a case study, H$β$, H40$α$, and free-free emissions are investigated using the Multi Unit Spectroscopic Explorer at the Very Large Telescope of the European Southern Observatory (MUSE/VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA). The H$β$ image obtained by MUSE identifies star-forming regions outside the nuclear regions, suggesting a disk-wide starburst. In contrast, the H40$α$ image obtained by ALMA identifies a nuclear starburst where optical lines are undetected due to dust extinction ($A_{\rm V}\sim25$). Combining both MUSE and ALMA observations, we conclude that the total SFR is $49\pm2~M_{\odot}$~yr$^{-1}$ and the contributions from nuclear and disk-wide starbursts are $\sim34~\%$ and $\sim66~\%$, respectively. This suggests the dominance of disk-wide star formation in NGC~3256. In addition, pixel-by-pixel analyses for disk-wide star-forming regions suggest that shock gas tracers (e.g., CH$_3$OH) are enhanced where gas depletion time ($τ_{\rm gas}$=$M_{\rm gas}/SFR$) is long. This possibly means that merger-induced shocks regulate disk-wide star formation activities.

description: It is shown that earthquakes do not know how large they will become, at least from the information collected at seismic catalogs. In other words, the magnitude is independent on previous magnitudes as well as on the waiting time between previous earthquakes. In contrast, the time to the next event does depend on the magnitude. Also it is argued that SOC systems do not necessarily shown a Poisson-type behavior in time, and SOC does not exclude the possibility of some degree of prediction.

description: Twisted van der Waals materials have become a paradigmatic platform to realize exotic correlated states of matter. Here, we show that a twisted dichalcogenide bilayer (WSe$_2$) encapsulated between a magnetic van der Waals material (CrBr$_3$) features flat bands with tunable valley and spin flavors. We demonstrate that, when electron-electron interactions are included, spin-ferromagnetic and valley-ferromagnetic states emerge in the flat bands, stemming from the interplay between correlations, intrinsic spin-orbit coupling and exchange proximity effects. We show that the specific symmetry broken state is controlled by the relative alignment of the magnetization of the encapsulation, demonstrating the emergence of correlated states controlled by exchange bias. Our results put forward a new van der Waals heterostructure where symmetry broken states emerge from a genuine interplay between twist engineering, spin-orbit coupling and exchange proximity, providing a powerful starting point to explore exotic collective states of matter.

description: The equation of state (EOS) of dense matter and neutrino mean free path (NMFP) in a neutron star have been studied by using relativistic mean field models motivated by effective field theory (ERMF). It is found that the models predict too large proton fractions, although one of the models (G2) predicts an acceptable EOS. This is caused by the isovector terms. Except G2, the other two models predict anomalous NMFP. In order to minimize the anomaly, besides an acceptable EOS, a large M* is favorable. A model with large M* retains the regularity in the NMFP even for a small neutron fraction.

In magnetic fields $H direction of the RuO2 lattice, is detected by spectroscopic imaging. Each vortex exhibits one flux quantum and a strong zero-bias conductance peak.

While researchers have used proxy reports or correlates like caste to trace networks, we map networks by surveying friends of respondents. We use participation in a women's education program to identify increases in female power, as well as stronger and more diverse networks. We study the ways in which networks affect individuals, namely learning and influence. Finally, we characterize the benefits of using survey data rather than proxies to identify networks. Our results linking networks to child nutrition should also inform child health policy.

Evaluation vertical strategies in CRM using an object-oriented approach
Creators: name: Parkinson, Pierre
Publisher: name: University of British Columbia
Year: 2009

description: Software vendors are required to constantly adjust their product strategies to maintain the competitiveness of their products as they evolve through the product lifecycle. Customer Relationship Management (CRM) software reached, what many considered, the mature stage of its lifecycle in the year 2000. To prevent sales from stagnating in a maturing market, some CRM vendors adopted a strategy of developing vertical CRM solutions to continue sales growth by exploiting well-defined niche markets. To develop a vertical CRM product it is necessary to create a single solution that can easily be customized to suit the needs of a set of companies in a defined industry. The objective of this paper is to investigate if an object-oriented business modeling technique is appropriate for defining vertical CRM solutions. To investigate the appropriateness of an object-oriented business modeling technique, object-oriented business models were created for two financial services organizations and then compared to an actual vertical CRM solution that was known to be successful. The results of the analysis demonstrate that object-oriented modeling techniques can be used successfully to both define the requirements for vertical CRM solutions, as well as to test if a vertical CRM solution meets those requirements. The implication of this research is that object-oriented business analysis shows promise in defining vertical CRM solutions and that this technique could be adopted by industry to accelerate the development cycles of vertical CRM solutions.

Non-traditional therapy formats: would clinicians implement guided self-help?
Creators: name: Plasencia, Maribel
Publisher: name: No Publisher Supplied
Year: 2021

description: The current study evaluated knowledge of and attitude towards a scalable, novel therapy format (Guided Self-Help; GSH) among evidence-based clinicians who treated one or more of the following disorders: panic disorder, major depressive disorder, bulimia nervosa, binge-eating disorder, and generalized anxiety disorder. A total of 155 out of 256 individuals recruited online and at professional conferences were eligible after completing a screening questionnaire. The subsequent study survey assessed whether clinicians had experience utilizing GSH, measured their confidence in defining GSH, evaluated their ability to define it, and asked whether clinicians would hypothetically utilize GSH with a fictional client. The fictional client presented to each clinician had a diagnosis that matched the clinicians’ specialization. Additionally, each case’s severity was determined from a literature review of the average profiles of individuals recruited in GSH trials.Analyses indicated that clinicians predicted their knowledge of GSH with an average confidence of 50.41%, and that less than 10% of individuals had ever implemented GSH as a stand-alone treatment (i.e., not as an adjunct to standard therapy). Additionally, after reading fictional vignettes of client cases, the average hypothetical use of GSH was approximately 50%. Exploratory analyses indicated that hypothetical use was predicted by two subscales of the Evidence-Based Practice Attitudes Scale: Openness and Appeal. Study findings suggest that evidence-based clinicians do not uniformly know of or endorse the use of a low-level intervention for mild to moderate cases of anxiety, depression, eating disorders (bulimia nervosa and binge eating disorder) or panic disorder. Analyses indicate that some of this variation may be predicted by a willingness to learn new treatments as well as knowledge of and training in such interventions. In fact, lack of training in GSH was one of the most frequently endorsed barriers to implementing GSH in clinical practice (n = 99, 64%). The current findings have implications for future studies on the dissemination and implementation of treatments like GSH in the United States, which have a greater potential for scalability. For example, it may be useful to investigate whether openness to new interventions as well as their appeal are modifiable factors in order to promote the use of such treatments in the United States. Additionally, measuring openness among clinicians may help health systems identify groups of clinicians who are more likely to implement novel delivery models of therapy. Finally, it may be important to incorporate scalable interventions into graduate programs as part of clinical training.
Impact of transforming to Conformal Fermi Coordinates on Quasi-Single Field Non-Gaussianity

description: In general relativity predictions for observable quantities can be expressed in a coordinate independent way. Nonetheless it may be inconvenient to do so. Using a particular frame may be the easiest way to connect theoretical predictions to measurable quantities. For the cosmological curvature bispectrum such frame is described by the Conformal Fermi Coordinates. In single field inflation it was shown that going to this frame cancels the squeezed limit of the density perturbation bispectrum calculated in Global Coordinates. We explore this issue in quasi single field inflation when the curvaton mass and the curvaton-inflaton mixing are small. In this case, the contribution to the bispectrum from the coordinate transformation to Conformal Fermi Coordinates is of the same order as that from the inflaton-curvaton interaction term but does not cancel it.

description: With an increasing aging population worldwide, there is a need for greater focus on the spirituality of older people, to better support them and lead them to an enhancement of their inner peace. This pilot research used a qualitative approach (with semi-structured interviews) in exploring spirituality with older people in residential aged care to understand more about the factors related to a sense of personal belief and connection that helped them in their daily lives. The research involved developing a rigorous exploratory process. The twenty-five (25) participants provided information about their rich experiences and their connections in four dimensions: (1) people, (2) creativity, (3) something bigger or higher than themselves and (4) their own inner being.

description: Black rings are the black objects found in $D$ spacetime dimensional gravity when $D \geq 5$. These have event horizon topology $S^{D-3}\times S^1$. In this work the solutions of the large $D$ membrane paradigm dual to stationary black rings in Einstein-Maxwell theory with or without cosmological constant are studied. It is shown that the first order membrane equations can only admit static asymptotically flat black rings, and the equilibrium angular velocity for the asymptotically AdS black rings at large $D$ was obtained. The thermodynamic and dynamic stability of the asymptotically flat black ring solutions is studied. The apparent shortcomings of some of these results are argued to be curable within the large $D$ membrane paradigm framework.
