Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: A close comparison of Kepler short- and long-cadence data released prior to 2011 Nov 1 has shown some subtle differences that make the short-cadence data superior to their long-cadence counterparts. The inevitable results of a faster sampling rate are present: the short-cadence data provide greater time resolution for short-lived events like flares, and have a much higher Nyquist frequency than the long-cadence data; however, they also contain fewer high-amplitude peaks at low frequency and allow a more precise determination of pulsation frequencies, amplitudes and phases. The latter observation indicates that Kepler data are not normally distributed. Moreover, a close inspection of the Pre-search Data Conditioned (PDC) long-cadence data show residuals that have increased noise on time-scales important to asteroseismology, but unimportant to planet searches.

description: Oxygen saturation is an important biological marker in tissue and is often quantified using optical imaging of intrinsic signals. However, due to the scattering property of biological tissue, most optical functional imaging methods are limited to the surface of the brain or have poor resolution. In this work, a single fiber optical system with zero source-detector separation is presented. The system is designed for measuring the oxygen saturation of deep brain structures by implanting the small diameter fiber probe into the tissue of interest. The system measures oxygen saturation using a steady-state spectroscopy method based on the absorption properties of oxy-hemoglobin and deoxy-hemoglobin. This thesis covers: (a) system design, including the optical simulation, system components and performance; (b) Monte Carlo simulations for wavelength determination, depth penetration and the received signal; (c) quantification method for the single fiber system; and (d) experimental results in a tissue phantom.
The irrepressible communicative power of pride
Creators: name: Shariff, Azim Fayaz
Publisher: name: University of British Columbia
Year: 2010

description: How do we decide who merits social status? According to evolutionary theories of emotion, the nonverbal expressions of pride and shame play a key role in this process, functioning as automatically perceived status signals. In this view, observers cannot avoid making status inferences on the basis of these expressions, even when contradictory contextual information about the expresser’s status is available. In twelve studies, my colleagues and I tested whether the nonverbal expression of pride sends a functional, automatically perceived signal about a social group member’s increased social status and whether implicit and explicit status judgments and corresponding decisions are influenced by this signal even contradicted by the context or situation. Results indicate that emotion expressions powerfully influence both implicit and explicit status judgments, at times neutralizing or even overriding situational knowledge, and this holds for implicit and explicit judgments of a target’s status, as well as more behavioural status-based decisions (i.e., whether to hire a target). These findings demonstrate the irrepressible communicative power of emotion displays, and the specifically, the pride expression’s function to uniquely communicate the high status of those who show it. Moreover, they indicate that status judgments can be informed as much(and often more) by automatic responses to nonverbal expressions of emotion as by rational, contextually bound knowledge. Discussion focuses on the implications of these findings for functional theories of emotion expressions.

description: Simulations are an important part of all areas of engineering, and electromagnetics is no exception. Finite-difference time-domain (FDTD) method has proven to be an attractive numerical method for simulating electromagnetic problems over the past few decades. There are certain drawbacks to the standard FDTD, namely: numerical dispersion and poor handling of anisotropic materials. To alleviate the numerical dispersion problem, the finite-difference time-domain method is derived on face-centered cubic (FCC) lattice as opposed to the standard cubic lattice. Several examples are presented to demonstrate the stability and accuracy of the proposed method. To address the other issue, handling anisotropic materials, an alternative grid known as Lebedev has previously been proposed. In this work, accurate implementation of perfect electric conducting boundary conditions on this grid, and two different techniques to couple Lebedev to the standard method for savings in memory will be presented, and supported by examples.
Local community perceptions on tourism and conservation in Tsavo National Park, Voi sub-county, Kenya: A social exchange theory approach
Creators: name: Odinga, Godfrey Hedga
Publisher: name: Journal of Tourism & Development
Year: 2023

description: This paper seeks to understand the perceptions of the local community in Voi sub-county on tourism and the conservation efforts in Tsavo National Park. Social Exchange Theory underpinned the theoretical framework of this study. Primary data were collected from the local community using questionnaire surveys conducted with the residents, and the data was analyzed. Results highlight that the community finds tourism in Tsavo National Park beneficial and would prefer increased tourism activities. The local community tends to recognize that nature, culture, and the political environment influence conservation. The study conclusively shows community support for the conservation efforts in Tsavo National Park. Results indicate that Social Exchange Theory can explain Voi residents' perceptions of tourism and conservation in Tsavo National Park. This study is expected to provide practical ways for concerned authorities to make future policies and strategies that relate to how local communities view tourism and conservation.

Historical Urban Tourism: The Evolution of Tourism in Colonial Lourenço Marques, Mozambique c.1920-1975
Creators: name: Rogerson, Christian M.
Publisher: name: Journal of Tourism & Development
Year: 2023

description: Scholarship is growing on cities as tourism destinations in the Global South. The vast majority of existing writings focus on contemporary issues around tourism development. This paper offers a contribution to address the historical knowledge gap within urban tourism research. The focus is Maputo, Mozambique's capital city, formerly known as Lourenço Marques. Using archival documentary material, the colonial tourism past of this city is examined. Lourenço Marques was the critical pivot for tourism in colonial Mozambique. Regional flows of tourists - most importantly from South Africa - were drivers of colonial tourism development. The strengthening of infrastructural linkages with South Africa meant that the city became a popular winter destination for visitors attracted by the city's continental European atmosphere and beaches. Of critical importance for tourism growth was the establishment of an accommodation services economy and the promotional activities of South African Railways. During the apartheid period Lourenço Marques continued as a growing tourism hub until the early 1970s when with political unrest and uncertainty linked to the anti-colonial struggle the tourism economy faltered and ended the colonial chapter of tourism for Lourenço Marques.

description: This paper presents an effective algorithm for selecting cluster heads in mobile ad hoc networks using ant colony optimization. A cluster in an ad hoc network consists of a cluster head and cluster members which are at one hop away from the cluster head. The cluster head allocates the resources to its cluster members. Clustering in MANET is done to reduce the communication overhead and thereby increase the network performance. A MANET can have many clusters in it. This paper presents an algorithm which is a combination of the four main clustering schemes- the ID based clustering, connectivity based, probability based and the weighted approach. An Ant colony optimization based approach is used to minimize the number of clusters in MANET. This can also be considered as a minimum dominating set problem in graph theory. The algorithm considers various parameters like the number of nodes, the transmission range etc. Experimental results show that the proposed algorithm is an effective methodology for finding out the minimum number of cluster heads.

description: Context. The HII region/PDR/molecular cloud complex S106 is excited by a single O-star. The full extent of the warm and dense gas close to the star has not been mapped in spectrally resolved high-J CO or [CII] lines, so the kinematics of the warm, partially ionized gas, are unknown. Whether the prominent dark lane bisecting the hourglass-shaped nebula is due solely to the shadow cast by a small disk around the exciting star or also to extinction in high column foreground gas was an open question until now. Aims. To disentangle the morphology and kinematics of warm neutral and ionized gas close to the star, study their relation to the bulk of the molecular gas, and to investigate the nature of the dark lane. Methods. We use the heterodyne receiver GREAT on board SOFIA to observe velocity resolved spectral lines of [C II] and CO 11-10 in comparison with so far unpublished submm continuum data at 350 micron (SHARC-II) and complementary molecular line data. Results. The high angular and spectral resolution observations show a very complex morphology and kinematics of the inner S106 region, with many different components at different excitation conditions contributing to the observed emission. The [C II] lines are found to be bright and very broad, tracing high velocity gas close to the interface of molecular cloud and HII region. CO 11-10 emission is more confined, both spatially and in velocity, to the immediate surroundings of S106 IR showing the presence of warm, high density (clumpy) gas. Our high angular resolution submm continuum observations rule out the scenario where the dark lane separating the two lobes is due solely to the shadow cast by a small disk close to the star. The lane is clearly seen also as warm, high column density gas at the boundary of the molecular cloud and HII region.

description: The Portmanteau Papers is a creative exploration, in novel form, of the social environments, narrative structures, and language that attend the so-called rise of the novel of the eighteenth century. This long-form fiction begins with the prints of William Hogarth, which it investigates as a visual analogue to the narrative patterns employed by period authors. By rereading and recreating selected elements of narrative implicit in Hogarth’s prints, the text of The Portmanteau Papers animates the tensions between modern and period prose forms. In doing so, the novel considers scholarship’s understanding of the on-going relationship between the contemporary novel and its eighteenth-century antecedents. Ultimately, the work argues for a theory of genre that includes the implications of artistic practice in addition to more usual formal or historical-cultural definitions. The story of The Portmanteau Papers explores the varied social and material contexts of eighteenth-century print culture, animating the range of contributions made by printers, booksellers, visual artists, authors, and readers. The Portmanteau Papers also creatively represents the contributions of women authors, especially novelist Sarah Scott, to the development of the novel, extending significant research done in this area over the last thirty years.

description: We predict the enhanced transmissivity of modulated slabs of layered superconductors for terahertz radiation due to the diffraction of the incident wave and the resonance excitation of the eigenmodes. The electromagnetic field is transferred from the irradiated side of a slab of layered superconductor to the other one by excited waveguide modes (WGMs) which do not decay deep into the slab, contrary to metals, where the enhanced light transmission is caused by the excitation of the evanescent surface waves. We show that a series of resonance peaks (with $T \sim 1$) can be observed in the dependence of the transmittance $T$ on the varying incidence angle $θ$, when the dispersion curve of the diffracted wave crosses successive dispersion curves for the WGMs.

description: The transport properties of superconducting single crystal Pb nanowires of 55 nm and 70 nm diameter are studied by standard four electrodes method. Resistance-temperature (R-T) scans and magneto-resistance (R-H) measurements show a series of resistance steps with increasing temperature and magnetic field as the wires are brought toward the normal state. The resistance-current (R-I) scans at different temperature and magnetic field show that the increase in R with I is punctuated with sharp steps at specific current values. We interpret these steps as consequence of phase slip centers (PSCs) in the superconducting wires enhanced by the presence of the normal Pt electrodes.

description: We investigate distribution of integral well-rounded lattices in the plane, parameterizing the set of their similarity classes by solutions of the family of Pell-type Diophantine equations of the form $x^2+Dy^2=z^2$ where $D>0$ is squarefree. We apply this parameterization to the study of the greatest minimal norm and the highest signal-to-noise ratio on the set of such lattices with fixed determinant, also estimating cardinality of these sets (up to rotation and reflection) for each determinant value. This investigation extends previous work of the first author in the specific cases of integer and hexagonal lattices and is motivated by the importance of integral well-rounded lattices for discrete optimization problems. We briefly discuss an application of our results to planar lattice transmitter networks.

description: Influences of economic environment contributing to change in factors of psychological distress were studied in relation to the central macroeconomic event of the Great Recession using an epidemiological approach with big data from a 24/7 crisis center in a large Canadian city. The data set consisted of all calls to the helpline from January 2005 to June 2012 identified as having a salient financial identity associated with money problems or unemployment. Gender-differentiated analysis revealed that prevalence of loneliness, depression, and anger related to personal finance consistently remained greater for males despite economic change. Prevalence of male anxiety and loneliness increased the most prior to the Great Recession; whereas, female anxiety and anger increased more than pre-recession loneliness. This thesis explores factors that may play a role in individual psychological distress and how applied psychology may benefit from an expanded and systemic understanding of a client in relation to the economy.
Reification of the Teenage Victim: How Canadian News Frames Cyberbullying as a Social Problem

description: This study utilizes framing theory to conduct a mixed method content analysis of Canadian print news coverage of four high-profile teen suicides linked with cyberbullying. Results demonstrate that print news discourse frames cyberbullying as a social problem. News coverage of these deaths emphasizes more female victims than males, demonstrating a predisposition to focus on more ideal victims in the construction of social problems. Each case involves a process of reducing complicated circumstances leading to the teen’s death down to overly simplified caricatures portrayed as victims for the cause of cyberbullying. The social problem frame emphasizes the need for public attention and awareness of cyberbullying as well as new legislation to address an emerging issue. It is unclear whether legal changes in response to such extreme cases will impact the more common instances of what the literature describes as cyberbullying.
Experiences of adult offspring of parents with a mental illness : putting together the pieces and making meaning of experiences
Creators: name: Harstone, Andrea Nancy
Publisher: name: University of British Columbia
Year: 2010

description: According to a 2009 Canadian national health survey approximately 12% of children under the age of 12 live in a household were the survey respondent reported one or more mood, anxiety or substance use disorder (Bassani, Padoin, Philipp & Veldhiuzen, 2009). In fact, one out of every five individuals will experience a mental illness during their lifetime. It is widely accepted that people who experience mental illness parent at the same rate as the general population. Numerous studies have explored the topic of children of parents with a mental illness. Early research focused on understanding the adverse effects on children and specifically on identifying risk for childhood psychopathy. More recently researchers have begun to explore the positive aspects of growing up with parental mental illness in light of children who are seen as demonstrating considerable resiliency. Strength-based aspects to the experiences of growing up as a child of parental mental illness have been included in some studies. The goal of this exploratory qualitative study was to explore the experiences of adults, who as children, grew up with a mentally ill mother and/or father. The method used included recruiting study participants using purposive sampling. The data collection and analysis was informed by grounded theory including a constant comparison of interview data and data analysis. Findings in this study supported previous research related to growing up with parental mental illness. Experiences of study participants were also similar to findings in existing research. Unique findings that would be worthy of further exploration included experiences of growing up in a two parent family with a father with a mental illness. Significant challenges with transitioning from adolescence to young adulthood were found across many of the interviews. The process of making meaning of experiences growing up in a family with parental mental illness as study participants experience their own significant life events was also found. These findings can inform policy and practice working with individuals and families who experience parental mental illness.
Towards Non-Destructive Detection of Photonic Qubits

description: Non-destructive detection of photonic qubits is an enabling technology for quantum information processing and quantum communication. For practical applications such as quantum repeaters and networks, it is desirable to implement such detection in a way that allows some form of multiplexing as well as easy integration with other components such as solid-state quantum memories. Here we propose an approach to non-destructive photonic qubit detection that promises to have all the mentioned features. Mediated by an impurity-doped crystal, a signal photon in an arbitrary time-bin qubit state modulates the phase of an intense probe pulse that is stored during the interaction. Using a thulium-doped waveguide in lithium niobate, we perform a proof-of-principle experiment with macroscopic signal pulses, demonstrating the expected cross-phase modulation as well as the ability to preserve the coherence between temporal modes. Our findings open the path to a new key component of quantum photonics based on rare-earth-ion doped crystals.
Coupled HBO and NBO variations in the Z source GX 5-1: inner accretion disk as the location of QPOs

description: The simultaneous and coupled evolution of horizontal branch oscillation (HBO) and normal branch oscillation (NBO) in Z-type sources suggests that the production of HBO is connected to NBO and is caused by changes in the physical/radiative properties of the inner accretion disk, although there is a lack of substantial spectral evidence to support this. In this {\it Letter}, we present the results of an analysis of a RXTE observation of a Z source GX~5-1, where the 6 Hz NBO is simultaneously detected along with a HBO at 51 Hz. The variations in the intensity and the associated power density spectrum indicate that the HBO and NBO are strongly coupled, originating from the same location in the inner accretion disk. The absence of HBO and NBO in the lower energy bands, an increase in the rms amplitude with energy and a smooth transition among them suggest that they are produced in the hot inner regions of the accretion disk. Based on a spectral analysis, we found a signature of changing or physically modified inner disk front during the coupled HBO and NBO evolution. We explore the various models to explain the observed phenomenon and propose that the NBO is affiliated to the oscillations in the thick/puffed-up inner region of the accretion disk.

description: This study examines the role that accounting plays in the delivery of health care to Canada’s First Nations, relying on the Health Centre of the Paul Band as a case study. While prior studies of relations between government and First Nations have focused on power, this study explores how relationships are formed and sustained in a network of actors with divergent interests. Drawing on practice theory (Schatzki, (1996) and Actor Network Theory (Latour, 1987), I investigate how accounting functions as a control device, and the role it plays in causing and resolving tensions in the network. The study also highlights how health care actors who are employees of both Government and the health center translate expressed government strategies into practices that sometimes produce unintended consequences. The study furthers understandings of Government-First Nations relationships and shows reasons that the outcomes of First Nations health care may be sub-par despite current levels of government spending. The variation in outcomes of health care in this band compared with outcomes for non-First Nations Canadians is explained through a novel concept (Structure Vs Practice), which reveals themes common to oppressive relations faced by First Nations in Canada and other countries. In conclusion, I propose that five themes bear on the outcomes of Canada’s First Nations health care programs: funding, barriers, enforcement, compliance, and self-determination.

description: In this paper we develop a finite-difference scheme to approximate radially symmetric solutions of the initial-value problem with smooth initial conditions in an open sphere around the origin, where the internal and external damping coefficients are constant, and the nonlinear term follows a power law. We prove that our scheme is consistent of second order when the nonlinearity is identically equal to zero, and provide a necessary condition for it to be stable order n. Part of our study will be devoted to compare the physical effects of the damping coefficients.

description: The regulation of gene expression in eukaryotes is a complex process that is controlled at many levels. Posttranscriptional regulation is performed by RNA-binding proteins that can effect the processing, localization and decay rates of mRNAs. One such family of RNA-binding proteins is Pumilio and FBF (Puf), which are conserved across eukaryotes. In this work, we have started to functionally characterize the nine puf+ genes found in the fission yeast Schizosaccharomyces pombe through the use of fluorescence localization studies, transcriptomics, RNA immunoprecipitation microarrays (RIP-chip) and molecular genetic techniques. Deletion strains of the classical puf+ genes were created and observed to have no phenotype, while strains overexpressing these genes did. This characterization also led to the finding that the puf+ genes of S. pombe are intracellularly localized in three distinct patterns of nucleolar, cytoplasmic and granular. The localizations were observed under heat shock conditions and only the cytoplasmic Pufs relocalized to foci in the cell that appeared to correspond to a stress granule marker. It was also observed that the Puf gene pfr1+ is involved in regulating flocculation, adhesion and invasive growth as the deletion strain cannot be induced to flocculate or invasively grow, while overexpression causes constitutive flocculation. Putative mRNA targets of Pfr1 regulation include pvg1+ and SPBPB7E8.01, which were identified by expression microarrays and RIP-chip analysis. These putative target genes were found to be repressors of flocculation, while the posttranscriptional regulation genes ccr4+ and ste13+were shown to be required for flocculation. The analysis of puf2 and puf4 using expression microarrays and RIP-chip to identify putative mRNA targets of these puf+ genes was also performed. This analysis indicated that puf2+ may be involved in regulating hexose import while puf4+ could be involved in the regulation of iron homeostasis. The results of this study have substantially contributed to our understanding of Puf function and posttranscriptional regulation in S. pombe.

description: We examine cluster states transformed by stochastic local operations and classical communication, as a resource for deterministic universal computation driven strictly by projective measurements. We identify circumstances under which such states in one dimension constitute resources for random length single-qubit rotations, in one case quasi-deterministically (N-U-N states) and in another probabilistically (B-U-B states). In contrast to the cluster states, the N-U-N states exhibit spin correlation functions that decay exponentially with distance, while the B-U-B states can be arbitrarily locally pure. A two-dimensional square N-U-N lattice is a universal resource for quasideterministic measurement-based quantum computation. Measurements on cubic B-U-B states yield two-dimensional cluster states with bond defects, whose connectivity exceeds the percolation threshold for a critical value of the local purity.

description: Cancer-related fatigue (CRF) is a common and debilitating symptom of cancer-treatment, described as a severe, feeling of fatigue, not improved by rest. A number of factors contribute to the occurrence of CRF. It has been observed using a variety of subjective scales, focusing on the psychological aspect. Few studies have assessed if neuromuscular function is related to CRF. It is unclear if sleep disorders, are associated with CRF. The purposes of this thesis were to 1) examine if neuromuscular variables are related to subjective feelings of fatigue and 2) determine if sleep disturbances are associated with CRF in cancer patients and survivors. Independent t-tests found no significant differences between subjective fatigued and non-fatigued groups in both neuromuscular and sleep parameters. However, sleep efficiency had a medium significant correlation with FACT-F scores (r= 0.31, p<0.05). While the results should be considered preliminary, it is suggested that sleep but not resistance to acute muscle fatigue due to exercise plays a role in CRF.

description: Rapid climate change events of the last glacial period are a prime example of the climate system’s ability to flip quickly between different states. These are associated with abrupt shifts in temperature, productivity and CO₂ and are commonly linked with major changes in circulation and sea-ice coverage in the high latitude North Atlantic Ocean. However, despite what is an increasingly well-established paradigm, major questions remain about the links between circulation, temperature, ice-sheet stability and CO₂ storage. This thesis presents a collection of new, high resolution records from Northeast Atlantic core ODP 980, which develop our understanding of the region’s role in rapid climate change. Analysis of two robust paleo-temperature proxies (percentage abundance and Mg/Ca of Neogloboquadrina pachyderma) reveals the first marine evidence that Heinrich stadials were intervals of extreme seasonality, characterised by very cold winters and increasingly warm summers. These rising temperatures which are attributed to weak Atlantic Meridional Overturning circulation (AMOC), climbing atmospheric CO₂ and the insulating effect of sea ice, support theories for ice-sheet destabilisation in an otherwise cold climate. High resolution boron isotope data also resolve major perturbations of CO₂ in the surface ocean at climate transitions. These show that the North Atlantic CO₂ sink, which persists during stadial periods, weakened dramatically at interstadial onset, likely maintaining elevated atmospheric CO₂ and uncovering a new role for the region in rapid climate change. Recent studies using authigenic coatings on foraminifera, have employed redox sensitive elements to reconstruct deep water oxygen concentrations. However, data from different oceanic settings, combined with a geochemical model, highlight the sensitivity of element enrichment to changes in surface productivity. The influence of sediment composition is also examined with regards to authigenic Nd/Mn ratios, which show exciting promise as a new indicator of AMOC strength. Together these authigenic data offer new opportunities for paleoclimate reconstruction.

description: Municipal wastewater effluent (MWWE) is a point-source of contamination to surface waters, and contains a mixture of nutrients and pharmaceuticals that are not completely eliminated during wastewater treatment processes. There have been many studies using reproductive endpoints to examine sub-lethal effects on fish sampled downstream from MWWE sources; however, few studies have examined effects on the stress performance of fish in the field, particularly in wild populations residing downstream from MWWE sources. The overall objective of this thesis was to determine whether exposure to MWWE in the field compromised the stress performance of native fish species in the Bow River, Calgary, Alberta. The hypothesis was that long-term exposure to MWWE would result in chronic stress and disruption of the hypothalamus-pituitary-interrenal (HPI) axis, leading to a reduced ability to respond to a secondary acute stressor and decreased energy stores due to enhanced energy demands. The results show that feral longnose dace (Rhinichthys cataractae; Chapter 2) and caged fathead minnows (Pimephales promelas; Chapter 3) sampled downstream from municipal wastewater treatment plants (WWTPs) in the Bow River, Calgary, Alberta, did not have elevated basal cortisol levels and were able to mount a cortisol response following exposure to an additional acute stressor. This suggests that there was no disruption in the HPI axis functioning. Furthermore, the energy stores in fish downstream from WWTPs were greater, which could be due to increased feeding, as fish were also greater in size. The effects detected on energy metabolism cannot be fully attributed to MWWE, as fish sampled from an upstream site also showed similar levels of glycogen stores as fish sampled from sites downstream from WWTPs. This suggests that stormwater and urban runoff may contribute to effects on the metabolism of fish.

description: Creative Problem Solving (CPS) is a structured process for navigating complex, open-ended problems and achieving creative results (Puccio, Murdock, & Mance, 2011). Although CPS has been the subject of significant scholarly attention (e.g. Parnes, 1987; Puccio et al., 2006; Isaksen & Treffinger, 2004; Puccio & Cabra, 2010), there is a paucity of research exploring the multiple outcomes that might emerge from a CPS. There is also a dearth of research that considers the context in which a CPS session occurs. This study addresses these gaps. This study is guided by the question, “What happens when employees operating within an organizational setting engage in CPS?” It draws its theoretical foundation from workplace learning theory and practice theory. Methodologically, it uses a single, interpretive case. Generating data through onsite observation, interviews, and document analysis, the researcher considered what happened before, during, and after a vice president in a global, publicly traded aviation company facilitated a CPS session for other members of the company’s executive team. The study found that the facilitator faced multiple struggles in introducing CPS; that participants adapted and innovated the process; that participants assessed the success of the CPS session based on criteria other than whether it achieved creative outcomes; and that contextual factors influenced what was deemed a successful solution. This study suggests that those responsible for guiding employees in introducing and facilitating CPS should consider the following: • Practitioner resources should further emphasize the political skills needed to introduce and facilitate CPS. • Proponents of CPS should highlight its multiple potential benefits—as opposed to focusing on the achievement of creative results. • Proponents should consider linking CPS to the process of strategic planning, since the two practices are compatible. • CPS-focused scholars should develop a version of CPS that might be more easily integrated into existing organizational practices. This study contributes to academic knowledge by pioneering a new methodological approach to studying CPS, advancing the empirical application of practice theory, and providing empirical substantiation for theoretical scholarly discussions around the strengths and limitations of community of practice (CoP) theories.

description: Lipid membranes are crucial structures in cells, composed of a bilayer of lipids, membrane associated proteins, and many other molecules. There is increasing evidence that membranes and lipids have important bioactive roles in many cellular processes. The thin, soft, dynamic, and chemically complex structure of lipid bilayers makes their characterization difficult. Atomistic molecular dynamics computer simulations have provided valuable insight into the structure and dynamics of model membrane systems. I used MD simulations to study free energies of lipids in various model membranes. The method of umbrella sampling was used to calculate the free energy for moving a single lipid from water to the center of a lipid bilayer. From these calculations, we have determined the free energy barrier for lipid flip-flop, and the free energy for lipid desorption. Phospholipids with relatively large and zwitterionic head groups were shown to translocate in a pore-mediated mechanism, whereas ceramide, cholesterol, and diacylglycerol with small polar head groups crossed in a solubility-diffusion mechanism. The presence of cholesterol in membranes increased the free energy barrier for DPPC flip-flop, cholesterol flip-flop, and pore formation. For different membranes, we calculate the free energy difference of a lipid monomer in the bilayer compared to bulk water, which is the excess chemical potential for the lipid monomer in that environment. We found that cholesterol prefers more ordered and rigid lipid bilayers, while DPPC had a lower excess chemical potential in a pure DPPC bilayer compared to a DPPC bilayer with 40 mol% cholesterol. Neither ceramide nor diacylglycerol had a strong preference for a model lipid raft bilayer, compared to a POPC bilayer, while cholesterol did have a large preference for the raft bilayer. This work expands our understanding of lipid membranes.
