description: The photon spectrum in macrocoherent atomic de-excitation via radiative emission of neutrino pairs (RENP) has been proposed as a sensitive probe of the neutrino mass spectrum, capable of competing with conventional neutrino experiments. In this paper we revisit this intriguing technique in order to quantify the requirements for statistical determination of some of the properties of the neutrino spectrum, in particular the neutrino mass scale and the mass ordering. Our results are sobering. We find that, even under ideal conditions, the determination of neutrino parameters needs experimental live times of the order of days to years for several laser frequencies, assuming a target of volume of order 100 cm3 containing about 10^21 atoms per cubic centimeter in a totally coherent state with maximum value of the electric field in the target. Such conditions seem to be, as of today, way beyond the reach of our current technology.

Πραγματοποιείται μία ποιοτική αλλά και ποσοτική καταγραφή των αρνητικών περιβαλλοντικών επιπτώσεων του παρόντος έργου, με την βοήθεια της μεθόδου (AKZ) Ανάλυσης Κύκλου Ζωής. Για την διεξαγωγή της και την παραγωγή ενός αξιόπιστου αποτελέσματος, χρειάζεται να παρθούν τα απαραίτητα στοιχεία εκπόνησης του έργου από τον ΑΔΜΗΕ. Η ΑΚΖ βοηθάει τόσο στην κατανόηση των περιβαλλοντικών επιβαρύνσεων της ηλεκτροδότησης της Κρήτης όσο και μελλοντικά τους εκάστοτε υπεύθυνους να πάρουν κατάλληλες ενεργειακές αποφάσεις. Αυτό επιτυγχάνεται καθώς εξετάζονται οι περιβαλλοντικές επιπτώσεις σε ολόκληρο τον κύκλο ζωής του έργου. Έτσι, αίρεται οριστικά ο ενεργειακός αποκλεισμός της Κρήτης και  καθίσταται πράσινη η ηλεκτροδότηση του νησιού  διότι θα μπει τέλος στην εξάρτηση της Κρήτης από τους αυτόνομους ρυπογόνους σταθμούς παραγωγής που θα κλείσουν.
Three essays on adolescent social networks, body culture, and dieting

Year: 2008

description: This dissertation focuses on the social causes and consequences of dieting, an outcome that has been under-theorized in contemporary research. I present three papers examining the complex relationship between dieting, friendship networks, and cultural body ideals. Drawing on qualitative and quantitative data, I argue that dieting is a gendered symbolic behavior associated with peer group status and social network embeddedness. The first chapter presents a qualitative analysis of adolescent male body image. I examine how young men perceive, interpret, and are affected by mainstream cultural messages about appearance. While some boys do feel pressured to strive for muscularity, and experience social and self-esteem consequences when they fail to achieve it, there is more diversity among how men interpret body ideals and are affected by them than among women. This project elucidates how cultural male body ideals manifest in the lives of adolescent boys and illustrates the strategies young people use to interpret and evaluate complex cultural messages. In the second chapter, I present a theoretical framework that conceptualizes dieting as a potential pathway to status and peer esteem for young women. I conclude that dieting is less likely when girls have alternative pathways to status which also provide them with an alternative to popular culture's emphasis on the thin ideal. One such pathway is participation in sports, which provides peer esteem and an ideal that emphasizes fitness and performance. This demonstrates that, while adolescent girls are clearly influenced by body ideals, alternative ideologies may translate in to observable reductions in dieting. In the third chapter, I study the extent to which adolescents' opinions about their weight and weight-related behaviors are related to how their social network embeddedness. I find that friendship network size matters and not the weight beliefs of those in one's network. Boys who have more weak ties in their networks are less likely to diet, while a girl's risk of dieting decreases as the number of strong ties in her network increases. This suggests perhaps a reverse causality process. Adolescents who identify as overweight may do so because they have smaller social networks.

Contemporary Polish Security Policy: Are NATO Benefits at Risk?
Creators: name: Kanios, Nicholas Constantine
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: What the future holds for Poland's reliance on the North Atlantic Treaty Organization (NATO) is unknown. As the war in Afghanistan dwindles down, NATO's members look forward to bringing home their troops and to reducing further their military budgets. A military capability gap on both sides of the Atlantic is Poland's primary concern, even if the US narrows this gap with its presence in Europe. As a result, Poland's security concerns resurfaced when America announced a strategic shift from Europe towards Asia in January 2012. America has pledged to continue its NATO commitments as a reassurance to European security. The Polish political elite, however, is skeptical about NATO's future ability to provide security to Poland's territory. This paper addresses whether a shift in US military strategy towards Asia and Europe's declining military budgets pose a threat to Poland's security apparatus. The author argues that, in spite of concerns from either sides of the Atlantic, an American strategic refocus toward the Asian-Pacific will not threaten Poland's security.

description: The purpose of this qualitative study is to enrich the understanding of the counselling and psychotherapy experiences of women who have previously or currently worked in the Canadian sex industry. I conducted semi-structured interviews with 6 participants ranging in age from 19 to 52 who described an individual counselling experience in which they revealed their sex work employment status. I analyzed the interview drawing from a Gadamerian hermeneutic phenomenological approach grounded in feminist standpoint theory. The results revealed 17 themes organized in 5 categories: (a) seeking counselling, (b) the therapeutic relationship, (c) disclosure of sex work, (d) counselling outcomes, and (e) recommendations for counsellors working with sex workers. The results shed light on indoor sex worker clients’ heterogeneous counselling needs, expectations, and experiences, providing valuable considerations for culturally responsive and socially just practice with sex workers. The discussion of the results reflects previous research studies, clinical implications, and suggestions for future research.

description: Researchers investigated effects of a 20-week integrative intervention (IIG) assessing the physical and psychosocial health of breast cancer survivors. This retrospective study included 70 survivors randomized into 4 groups: IIG, exercise only (EX), recreation therapy only (RT), or control group (CO) and assessed at baseline, week 8, and post intervention. Three days a week the IIG exercised at low to moderate-intensity 60 minutes, and recreation therapy 30 minutes, EX did exercise only, RT did recreation therapy only and the control group, no intervention for the first 8 weeks. Following week 8 assessments, all groups received IIG intervention. Results revealed that the IIG promoted positive changes in cardiorespiratory function (p= .001), muscular fitness (p≤.0005), fatigue (p≤.0005), and quality of life (p= .001) within the first 8 weeks of a 20-week rehabilitation program. In conclusion, a combined exercise and psychosocial intervention promotes improvements in physiological and psychological needs of breast cancer survivors.

Stereotypes (Social psychology)

description: Humans draw on their stereotypic beliefs to make assumptions about others. Even though prior research has shown that individuals respond socially to media, there is little evidence with regards to learners stereotyping and categorizing pedagogical agents. This study investigated whether learners stereotype a pedagogical agent as being knowledgeable or not knowledgeable and how this acuity influenced learning. Participants were assigned to four experimental conditions differing by agent (scientist or artist) and tutorial type (nanotechnology or punk rock). Quantitative analyses indicated that agents were stereotyped depending on their image and the academic domain under which they functioned. Regardless of tutorial, participants assigned to the artist agent recalled more information than participants assigned to the scientist agent. Learning differences between the groups varied according to whether agent appearance fit the content area under investigation. Qualitative results indicated learner’s stereotypic expectations as well as their unwillingness to draw conclusions based on visual appearance.

description: Compact steep spectrum (CSS) and GHz-peaked spectrum (GPS) radio sources represent a large fraction of the extragalactic objects in flux density-limited samples. They are compact, powerful radio sources whose synchrotron peak frequency ranges between a few hundred MHz to several GHz. CSS and GPS radio sources are currently interpreted as objects in which the radio emission is in an early evolutionary stage. In this contribution I review the radio properties and the physical characteristics of this class of radio sources, and the interplay between their radio emission and the ambient medium of the host galaxy.

description: We present early results from the JCMT Plane Survey (JPS), which has surveyed the northern inner Galactic plane between longitudes l=7 and l=63 degrees in the 850-μm continuum with SCUBA-2, as part of the James Clerk Maxwell Telescope Legacy Survey programme. Data from the l=30 degree survey region, which contains the massive star-forming regions W43 and G29.96, are analysed after approximately 40% of the observations had been completed. The pixel-to-pixel noise is found to be 19 mJy/beam, after a smooth over the beam area, and the projected equivalent noise levels in the final survey are expected to be around 10 mJy/beam. An initial extraction of compact sources was performed using the FellWalker method resulting in the detection of 1029 sources above a 5-σ surface-brightness threshold. The completeness limits in these data are estimated to be around 0.2 Jy/beam (peak flux density) and 0.8 Jy (integrated flux density) and are therefore probably already dominated by source confusion in this relatively crowded section of the survey. The flux densities of extracted compact sources are consistent with those of matching detections in the shallower ATLASGAL survey. We analyse the virial and evolutionary state of the detected clumps in the W43 star-forming complex and find that they appear younger than the Galactic-plane average.

The goal is to unify the universal coefficient theorems found in the literature and to develop a machinery for proving new ones. Among the universal coefficient theorems covered by our methods we find, besides all the classic examples, several exotic examples arising from the KK-theory of C*-algebras and also Neeman's Brown-Adams representability theorem for compactly generated categories.

I choose $Im F^{(1)}(s,0)+Im F^{(2)}(s,0)$ as given by Particle Data Group (PDG) fits to total cross sections. The PDG formula is extended to non-zero momentum transfers using partial waves of $Im F^{(1)}$ and $Im F^{(2)}$ motivated by Pomeron pole and 'grey disk' amplitudes . $Re F(s,t)$ is deduced from real analyticity: I prove that $Re F(s,t)/ImF(s,0) \rightarrow (π/\ln{s}) d/dτ(τIm F(s,t)/ImF(s,0) )$ for $s\rightarrow \infty$ with $τ=t (ln s)^2$ fixed, and apply it to $F^{(2)}$.Using also the forward slope fit by Schegelsky-Ryskin , the model gives real parts,differential cross sections for $(-t) 0.5 TeV$, with PDG2013 total cross sections , and Schegelsky-Ryskin slopes as input, $σ_{inel} (s) =22.6 + .034 ln s + .158 (ln s)^2 mb , and σ_{inel} / σ_{tot} \rightarrow 0.56, s\rightarrow \infty ,$ where $s$ is in $GeV^2$

description: The small molecular cloud Lynds 1634 contains at least three outflow sources. We found one of these, IRS 7, to be variable with a period of 37.14 +/- 0.04 days and an amplitude of approximately 2 mag in the Ks band. The light curve consists of a quiescent phase with little or no variation, and a rapid outburst phase. During the outburst phase, the rapid brightness variation generates light echoes that propagate into the surrounding molecular cloud, allowing a measurement of the distance to IRS 7 of 404 pc +/- 35 pc. We observed only a marginally significant change in the H - K color during the outburst phase. The K-band spectrum of IRS 7 shows CO bandhead emission but its equivalent width does not change significantly with the phase of the light curve. The H_2 1-0 S(1) line emission does not follow the variability of the continuum flux. We also used the imaging data for a proper motion study of the outflows originating from the IRS 7 and the FIR source IRAS 05173-0555, and confirm that these are indeed distinct outflows.

In this article we prove the conjecture for the case of two Puiseux pairs and monodromy with distinct eigenvalues. The hypothesis on the monodromy implies that the $b$-exponents coincide with the opposite of the roots of the Bernstein polynomial, and we compute the roots of the Bernstein polynomial.

description: Identifying the most influential spreaders is an important issue in controlling the spreading processes in complex networks. Centrality measures are used to rank node influence in a spreading dynamics. Here we propose a node influence measure based on the centrality of a node and its neighbors' centrality, which we call the neighborhood centrality. By simulating the spreading processes in six real-world networks, we find that the neighborhood centrality greatly outperforms the basic centrality of a node such as the degree and coreness in ranking node influence and identifying the most influential spreaders. Interestingly, we discover a saturation effect in considering the neighborhood of a node, which is not the case of the larger the better. Specifically speaking, considering the 2-step neighborhood of nodes is a good choice that balances the cost and performance. If further step of neighborhood is taken into consideration, there is no obvious improvement and even decrease in the ranking performance. The saturation effect may be informative for studies that make use of the local structure of a node to determine its importance in the network.

description: We construct a one-particle TOA operator $\mathcal{\hat{T}}$ canonically conjugate with the Hamiltonian describing a free, charged, spin-$0$, relativistic particle in one spatial dimension and show that it is maximally symmetric. We solve for its eigenfunctions and show that they form a complete and non-orthogonal set. Plotting the time evolution of their corresponding probability densities, it implies that the eigenfunctions become more localized at the origin at the time equal to their eigenvalues. That is, a particle being described by an eigenfunction of $\mathcal{\hat{T}}$ is in a state of definite arrival time at the origin and at the corresponding eigenvalue. We also calculate the TOA probability distribution of a particle in some initial state.

description: Sarcopenia is defined as the progressive, systematic loss of skeletal muscle mass, function and quality that is associated with aging or atrophy. There are multiple methods for diagnosing sarcopenia, with body composition tools being increasingly utilised. The presence of sarcopenia has been shown to be associated with poorer outcomes for patients with malignancy. This thesis describes an initial study investigating the use of body composition software in identifying sarcopenia in a population of patients with upper gastrointestinal (UGI) malignancies undergoing surgical resection at a single institution. The impact of sarcopenia on outcomes will also be investigated.

The epigenetic effects of prenatal folate supplementation on male CD1 mouse fetuses exposed in utero to arsenic
Creators: name: Tsang, Verne
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Inorganic arsenic (iAs) is a common drinking water contaminant and transplacental carcinogen in mice, and possibly in humans. Recent animal studies suggest the mechanism of iAs carcinogenesis may include competition for S-adenosylmethionine required for both iAs and fetal DNA methylation, causing aberrant gene expression and cancer in adulthood. We exposed mouse dams to 0 or 85ppm iAs in drinking-water while feeding them a diet containing either 2.2 or 11mg/kg of folate. At gestational day (GD) 18, we examined DNA methylation patterns in fetal livers using CpG-island microarrays. Our results show that compared to folate supplementation alone, combined exposure to iAs and folate dramatically increased the number of CpG islands with altered methylation patterns. The most affected genes were associated with the cancer, neurological development, and cell signaling networks. This data raises concern about the efficiency and potential risks associated with folate supplementation in human populations chronically exposed to iAs.
Kant's moral philosophy and the role of the highest good
Creators: name: Bhardwaj, Kiran
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Described as the union of complete virtue and complete happiness in accordance with such virtue, the concept of the highest good draws together Kant's account of moral virtue with special features of humans: our need for happiness and hopes for justice. However, the highest good fails to perform its function in Kant's theory if either of two strong criticisms holds: if it is inconsistent with Kant's account of moral motivation, or if it is unimportant in moral action. I argue that a historical survey of Kant's explanation of the highest good shows how improved argumentation in the later works helps Kant to resolve any apparent inconsistency. And while the highest good is not important in everyday moral action, I conclude that we should use it to resolve worries about the futility of moral action. As a result, the highest good has an undeniably central role in Kant's ethics.

description: Debate persists as to whether the cosmological constant $Λ$ can directly modify the power of a gravitational lens. With the aim of reestablishing a consensus on this issue, I conduct a comprehensive analysis of gravitational lensing in the Schwarzschild--de Sitter spacetime, wherein the effects of $Λ$ should be most apparent. The effective lensing law is found to be in precise agreement with the $Λ=0$ result: $α_\mathrm{eff} = 4m/b_\mathrm{eff}+15πm^2/4b_\mathrm{eff}^2 +O(m^3/b_\mathrm{eff}^3)$, where the effective bending angle $α_\mathrm{eff}$ and impact parameter $b_\mathrm{eff}$ are defined by the angles and angular diameter distances measured by a comoving cosmological observer. [These observers follow the timelike geodesic congruence which (i) respects the continuous symmetries of the spacetime and (ii) approaches local isotropy most rapidly at large distance from the lens.] The effective lensing law can be derived using lensed or unlensed angular diameter distances, although the inherent ambiguity of unlensed distances generates an additional uncertainty $O(m^5/Λb_\mathrm{eff}^7)$. I conclude that the cosmological constant does not interfere with the standard gravitational lensing formalism.

description: Replica exchange (RE) is one of the most popular enhanced-sampling simulations technique in use today. Despite widespread successes, RE simulations can sometimes fail to converge in practical amounts of time, e.g., when sampling around phase transitions, or when a few hard-to-find configurations dominate the statistical averages. We introduce a generalized RE scheme, density-of-states-informed RE (g-RE), that addresses some of these challenges. The key feature of our approach is to inform the simulation with readily available, but commonly unused, information on the the density of states of the system as the RE simulation proceeds. This enables two improvements, namely, the introduction of resampling moves that actively move the system towards equilibrium, and the continual adaptation of the optimal temperature set. As a consequence of these two innovations, we show that the configuration flow in temperature space is optimized and that the overall convergence of RE simulations can be dramatically accelerated.

description: Using first-principles evolutionary simulations, we have systematically investigated phase stability in the Hf-O system at pressure up to 120 GPa. New compounds Hf5O2, Hf3O2, HfO and HfO3 are discovered to be thermodynamically stable at certain pressure ranges and a new stable high-pressure phase is found for Hf2O with space group Pnnm and anti-CaCl2-type structure. Both P62m-HfO and P4m2-Hf2O3 show semimetallic character. Pnnm-HfO3 shows interesting structure, simultaneously containing oxide O2- and peroxide [O-O]2- anions. Remarkably, it is P62m-HfO rather than OII-HfO2 that exhibits the highest mechanical characteristics among Hf-O compounds. Pnnm-Hf2O, Imm2-Hf5O2, P31m-Hf2O and P4m2-Hf2O3 phases also show superior mechanical properties, these phases can be quenched to ambient pressure and their properties can be exploited.

It is shown that these nodes have an excellent performance also from several alternative points of view, providing a numerically stable surface reconstruction, starting from both the elevation and the slope data. Sampling at these nodes allows for a more precise recovery of the coefficients in the Zernike expansion of a wavefront or of an optical surface.

description: This work traces the development of a new, female-friendly courtly model in Hartmann von Aue’s Erec through a close examination of the development of female subjectivity. I argue that female subjectivity is affirmatively realized in Erec through a succession of private and semi-private spaces, whose physical and/or metaphorical placement outside the purview of theretofore understood methods of gauging the acceptability of feminine behavior, promotes a simultaneously separate and equal role for courtly ruling women.

description: Purpose of Project: This project aimed to employ a culturally sensitive lifestyle modification toolkit to manage hypertension among West African immigrants aged 21–65.Methods: This quasi-experimental project was conducted in a West African Church in central New Jersey and over Zoom for six weeks. Blood pressures were measured pre-intervention and post-intervention. The hypertension Evaluation of Lifestyle and Management scale (HELM) was used to assess knowledge and lifestyle management, while the Hill-Bone scale (HB-MAS) was used to assess medication adherence.Results: There were statistically significant improvements at the alpha=0.05 threshold. The Wilcoxon signed rank sum test revealed statistically significant improvement in HELM questionnaire scores (S=52.5, p=0.0001), HB-MAS questionnaire scores (S=7.0, p=0.0001), and systolic S= -51.5 (p=0.0002) and diastolic (S= -52.5, p=0.0001) blood pressure measurements.Implications for Practice: This project’s findings support other evidence-based studies that have concluded that hypertension education is a practical and effective strategy to reduce racial disparities in hypertension control. Congruently, a culturally sensitive approach to dealing with high-risk West African immigrants might be more effective in controlling hypertension among this population.

description: PURPOSEInitiate preparing the patient for an emergent sternal re-entry and gain chest re-entry within 5 minutesMETHODSIn November 2021, the pilot project was implemented in an Acute Care facility located in Southern New Jersey with participation from a total of 10 nightshift surgical ICU nurses. Development of this pilot project consisted of developing a mock “open” chest code based of the current policy at the facility and building a manikin to use for the simulation. The implementation took place over approximately three consecutive weekend nightshifts which consisted of mock “open” chest codes with simulation-based technology, a debriefing between the pre/post mock “open” chest code, and a post debriefing survey. Evaluation of the debriefing effectiveness was an anonymous survey which was handed into after the debriefing, pre/post mock “open” chest code times were recorded and analyzed to measure if there was a change in time before and after the debriefing.RESULTSThere was a total of three groups that participated in the “mock” sternal re-entry codes with a total of 10 participants. There was no increase in times for any milestone for any group. The average decrease in time to chest re-entry was 129.7 ± 79.2 seconds. Due to the small sample size the results are limited. All times were decreased after the debriefing sessions. Utilization of simulation-based technology in the form of “mock” open chest codes improved efficiency in sternal re-entry. This was a pilot project, and a larger sample size would be recommended for further study.ImplicationsImplementing the “mock” sternal re-entry codes with a debriefing in the cardiac surgical intensive care unit may reduce time to chest re-entry and decrease mortality rate among the patients in need of emergent sternal re-entry at the bedside by providing simulation-based learning for the inexperienced. This may also in turn lead to a decrease in patient cost of care, intensive care unit stay, and decrease cost for patient requiring emergent sternal re-entry.KEYWORDS“low frequency, high risk events,” mock code, sternal re-entry, cardiac surgery, resuscitation, debriefing
title: Strategic Workforce Planning: A Proposition for Detonating the Demographic time-Bomb in the Kenyan Public Service
Creators: name: Nyakango, M
Publisher: name: University of Liverpool Repository

description: The demographics of the Kenyan public service are poised to change in unpredictable ways in the next few years, especially regarding diversity in the workplace. For a country with a bulging youth population whereby about 61% of the population is under the age of 24 years with those aged 14 years and below accounting for about 42% , it is worrying that the workforce components are neither inventoried nor planned for, especially in the public sector. This sector is also the largest employer as is the case in most parts of sub-Saharan Africa (SSA). This study seeks to find out what it would take to improve the practice of a large public sector organisation, KNBS, using strategic workforce planning to tackle its workplace challenges. There is an attempt to mitigate the imminent and/or looming skills shortages in the light of the mass exit of the ‘baby boomer’ generation from the workplace on the one hand, and the government’s policies restricting the hiring of younger generation recruits, on the contrary. The study uses participatory action research to highlight the need for a strategic workforce plan (SWP) as a medium to long-term coping strategy. The study undertakes the first full cycle of the Participatory Action Research spirals involving participants within the workplace. These participants, drawn from various directorates and departments within KNBS, split into focus groups. An analysis of workplace demographics provides a baseline to enable the development of a sustainable SWP, one that could be ‘rolled out’ across the country’s public sector. While recognising that many change initiatives fail due to lack of involvement of key stakeholders, this study engages the whole spectrum of employees – not just as information sources, but also significant actors in the process of crafting a new 5-year SWP for KNBS.

description: We present a study of the behavior of Saturn's A ring outer edge, using images and occultation data obtained by the Cassini spacecraft over a period of 8 years from 2006 to 2014. More than 5000 images and 170 occultations of the A ring outer edge are analyzed. Our fits confirm the expected response to the Janus 7:6 Inner Lindblad resonance (ILR) between 2006 and 2010, when Janus was on the inner leg of its regular orbit swap with Epimetheus. During this period, the edge exhibits a regular 7-lobed pattern with an amplitude of 12.8 km and one minimum aligned with the orbital longitude of Janus, as has been found by previous investigators. However, between 2010 and 2014, the Janus/Epimetheus orbit swap moves the Janus 7:6 LR away from the A ring outer edge, and the 7-lobed pattern disappears. In addition to several smaller-amplitudes modes, indeed, we found a variety of pattern speeds with different azimuthal wave numbers, and many of them may arise from resonant cavities between the ILR and the ring edge; also we found some other signatures consistent with tesseral resonances that could be associated with inhomogeneities in Saturn's gravity field. Moreover, these signatures do not have a fixed pattern speed. We present an analysis of these data and suggest a possible dynamical model for the behavior of the A ring's outer edge after 2010.

description: Parents of individuals with autism spectrum disorders experience high levels of stress. Nonetheless, they possess resilient qualities and rely on formal and informal supports to cope with challenges. The aim of this study was to explore the stressors and supports parents of individuals with moderate to severe autism experience across the life cycle stages of their child, from early childhood to adulthood. Semi-structured interviews were conducted with nine parents from eight families across different stages, who identified the challenges and supports they experienced and described how these have changed over time. Analysis of the data revealed themes of stress and support specific to individual stages and overlapping across stages. Implications for practice include educating teachers and service providers about autism, provision of family-centered services, and addressing finance and systemic concerns.
Bursting of Dilute Emulsion-Based Liquid Sheets Driven by a Marangoni Effect

description: We study the destabilization mechanism of thin liquid sheets expanding in air and show that dilute oil-in-water emulsion-based sheets disintegrate through the nucleation and growth of holes that perforate the sheet. The velocity and thickness fields of the sheet outside the holes are not perturbed by holes and hole opening follows a Taylor-Culick law. We find that a pre-hole, which widens and thins out the sheet with time, systematically precedes the hole nucleation. The growth dynamics of the pre-hole follows the law theoretically predicted for a liquid spreading on another liquid of higher surface tension due to Marangoni stresses. Classical Marangoni spreading experiments quantitatively corroborate our findings.

Antonio Colinas: The Re-writing of Sepulcro en Tarquinia in Larga carta a Francesca
Creators: name: Fellie, Maria C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This study begins by summarizing the life and literary accomplishments of Antonio Colinas, a contemporary Spanish poet, and his development as a writer over the past forty years. The proposal is that Colinas' poem Sepulcro en Tarquinia (1975) is the basis for his novel Larga carta a Francesca (1986). Chapter two introduces the poem and analyzes its language, imagery, and main themes, among these love, illness, and death. The following chapter compares the themes, language, imagery, and cultural references (Italy) between the poem and novel, determining that all of these coincide in some way except the ending of the novel. Chapter four concludes that Colinas rewrote Sepulcro in Larga carta eleven years later, with a different ending, because of changing philosophies and his relatively recent incorporation of Taoist thought into his writing.
title: A market-based approach towards supporting entrepreneurship in developing countries: Assessing the business accelerator model in Egypt
Creators: name: Eid, W
Publisher: name: University of Liverpool Repository
Year: 2016

description: This research aims at exploring the accelerator business model in Egypt, a developing country, and its role as a for-profit organisation in empowering and strengthening opportunity entrepreneurs. After selecting an accelerator for the study, interviews were conducted to demonstrate how the business model operates. Six entrepreneurs that were sponsored by the accelerator were selected according to the nomination of the accelerator. A series of in-depth semi-structured interviews were conducted with the six participant entrepreneurs to gain an understanding about the benefits of being sponsored by the accelerator. In addition, a non-governmental organization was selected to explore how the accelerator model, a for-profit organisation, represents a new and different pathway in promoting opportunity entrepreneurship other than other traditional forms of support.

description: We report on six Chandra and one HST/WFC3 observation of CXO J122518.6+144545, discovered by Jonker et al. (2010) as a candidate hyperluminous X-ray source (HLX), X-ray bright supernova or recoiling supermassive black hole at $L_X = 2.2 \times 10^{41}$ erg/s (if associated with the galaxy at 182 Mpc). We detect a new outburst of the source in a Chandra image obtained on Nov 20, 2014 and show that the X-ray count rate varies by a factor $> 60$. New HST/WFC3 observations obtained in 2014 show that the optical counterpart is still visible at $g' = 27.1 \pm 0.1$, $1 \pm 0.1$ magnitude fainter than in the discovery HST/ACS observation from 2003. This optical variability strongly suggests that the optical and X-ray source are related. Furthermore, these properties strongly favour an HLX nature of the source over the alternative scenarios. We therefore conclude that CXO J122518.6+144545 is most likely an outbursting HLX. It is only the second such object to be discovered, after HLX-1 in ESO 243-49. Its high X-ray luminosity makes it a strong candidate to host an intermediate mass black hole.

Authoritarian Preference and Locus of Control in Russia

description: Political preferences and behavior are rooted in psychological traits. Locus of control theory describes in terms of internality or externality whether individuals believe they exercise a lot of influence over events in their lives, or whether they attribute such events to outside forces such as luck, fate, or some authority. I applied this theory to political science to explore whether this construct can predict authoritarian preference. I focused on Russia and hypothesized that Russians may be more predisposed toward an external locus of control and preference for authoritarianism than are citizens of liberal democracies. I use Pew Research Center’s Spring 2011 Survey data to test effects of locus of control on authoritarian preference, controlling for country and for economic strength preference. Preference for a strong economy most strongly correlates with preference for a strong-hand leader, but I also find a significant effect of locus of control and country on authoritarian preference.
