description: In this work, low temperature thermolysis of metal ethyl xanthates (M = Mo, Co, Fe, Ni) was used to prepare amorphous metal and mixed metal sulfide films on fluorine-doped tin oxide for the hydrogen evolution reaction (HER). Films prepared by dip-coating showed optimal coverage, as monitored by scanning electron microscopy, using high precursor solution concentrations and slow/fast dip-coating retraction rates with low/high volatility solvents. X-ray diffraction confirmed that the films are amorphous. Direct preparation of the active form of amorphous molybdenum disulfide (a-MoS2), proven by x-ray photoelectron spectroscopy, was done, exhibiting electrochemical activity consonant with activated a-MoS2 in the literature. The addition of cobalt and iron to a-MoS2 at an optimal composition of 3:1 Mo:M showed a slight enhancement to current densities. Amorphous iron and cobalt showed activity toward the HER. X-ray photoelectron spectroscopy confirmed the presence of metal sulfide and metal oxide species or homogeneous metal oxysulfide species.
title: The Ties that Do Not Bind. Group formation, polarization and conflict within networks of political elites in the medieval Roman Empire
Creators: name: Preiser-Kapeller, Johannes
Publisher: name: Journal of Historical Network Research
Year: 2020

description: This chapter aims at the exploration of concepts and methods of network and complexity theory as well as New Institutional Economics (NIE) for the analysis of the emergence of conflicts within ruling elites in pre-modern polities. From the point of view of NIE, Douglass C. North, John Joseph Wallis and Barry R. Weingast have pointed out the general structural weakness of pre-modern formations of power. This assumption will be tested against a comparative analysis of the structural and qualitative properties of elite networks, also in their temporal and spatial dynamics. The modelling of the relational web among elite members will also open a micro-perspective on the evolution and resilience of networks between actors within smaller groups and clusters in situations of conflict. Furthermore, it allows for a quantification of the size of conflicts within elite networks and the analysis of their temporal dynamics.

description: This thesis investigates the ability of a hovering bicopter to be self-stabilized in pitch and roll without the use of electronic sensors in those directions. A mathematical model of aircraft dynamics is developed in which the non-cyclic proprotors are allowed to precess freely as gyroscopes since these are known to embody stabilizing elements. In the prior art of bicopter oblique active tilting (OAT), the proprotors generate gyroscopic control moments only when forcibly tilted, and stabilization in pitch and roll requires electronic attitude sensors and actuator servos. A self-stabilized system, however, would reduce cost, stresses and energy consumption, and could be scalable without limit. Through analysis of the characteristic equations it is found that aircraft angular positions cannot be so stabilized, but their velocities can be, maintaining the benefits listed above. This stability is similar to that due the flybar damping system of early Bell helicopters and still useful in small models today.

description: We have used the Australia Telescope Compact Array to measure the absorption from the 2(0) - 3(-1}E 12.2 GHz transition of methanol towards the z=0.89 lensing galaxy in the PKS B 1830-211 gravitational lens system. Comparison of the velocity of the main absorption feature with the published absorption spectrum from the 1(0) - 2(-1)E transition of methanol shows that they differ by -0.6 +/- 1.6 km/s . We can use these observations to constrain the changes in the proton-to-electron mass ratio from z=0.89 to the present to 0.8 +/- 2.1 x 10^-7. This result is consistent, and of similar precision to recent observations at z = 0.68 achieved through comparison of a variety of rotational and inversion transitions, and approximately a factor of 2 better than previous constraints obtained in this source. Future more sensitive observations which incorporate additional rotational methanol transitions offer the prospect of improving current results by a factor of 5-10.

description: In this review we present results of our theoretical study of charge and spin ordering in strongly correlated electron systems obtained within various generalizations of the Falicov-Kimball model. The primary goal of this study was to identify crucial interactions that lead to the stabilization of various types of charge ordering in these systems, like the axial striped ordering, diagonal striped ordering, phase-separated ordering, phase-segregated ordering, etc. Among the major interactions that come into account, we have examined the effect of local Coulomb interaction between localized and itinerant electrons, long-range and correlated hopping of itinerant electrons, long-range Coulomb interaction between localized and itinerant electrons, local Coulomb interaction between itinerant electrons, local Coulomb interaction between localized electrons, spin-dependent interaction between localized and itinerant electrons, both for zero and nonzero temperatures, as well as for doped and undoped systems. Finally, the relevance of resultant solutions for a description of rare-earth and transition-metal compounds is discussed.

description: Rationale: In order to compete with the private sector in retaining highly competent and skilled nurses, it is critical to identify, through rigorous research methods, those system characteristics that contribute to or reduce attrition so that evidenced-based retention strategies can be designed and implemented in US Army primary care settings within the Military Health System.Hypotheses: This study tested three hypotheses: (a) the nursing practice environment is positively associated with team performance, clinic staff perception of overall patient safety, and staff nurse job satisfaction, and negatively associated with staff nurse intent to leave, (b) team performance is positively associated with clinic staff perception of overall patient safety and staff nurse job satisfaction, and negatively associated with staff nurse intent to leave, and (c) team performance mediates the relationship between the nursing practice environment and clinic staff perception of overall patient safety, staff nurse job satisfaction, and staff nurse intent to leave.Method: This is a cross-sectional, correlational study examining secondary data from 2016 representing 39 US Army primary care clinics located in eighteen states and Germany.Purpose: The purpose of this study is to examine the relationships among the nursing practice environment, team performance, clinic staff perception of overall patient safety, staff nurse job satisfaction, and staff nurse intent to leave in US Army primary care clinics. Findings: The findings of this study highlight the importance of a positive nursing practice environment, especially nurse manager ability, leadership, and support for nurses to clinic and staff nurse outcomes including intent to leave as an indicator of attrition.

title: Athens as a Small World

description: Athenian political life in the 460’s and 450’s BC centered on conflict between the Oligoi and the Demos, whose positions were articulated by Cimon and Pericles, and then Cimon’s successor, Thucydides son of Melesias. Through the building program debate in the ecclesia, and the success of Pericles over his opponent who was ostracized, the fissure between clusters was resolved, and the Demos got the upper hand. In 1998, Anthony Podlecki wrote a book called Perikles and his Circle, and before that Philip Stadter (1991) wrote an influential article entitled “Pericles Among the Intellectuals.” To their work, we now add a formal social network analysis to study the position of Pericles in the social network of intellectuals, artists, politicians, and cultural creatives in the mid-5th century BC. The study shows clusters of varying size and relative positions in which boundaries were fluid and there was much interaction. Women feature highly in betweenness centrality. The data set includes 328 nodes, and 754 edges, built around the ego-network of Socrates, of which Pericles, political figures, and the intellectuals are members. The data consists of an edge list drawn from all of Plato, Plutarch’s lives of Cimon, Pericles, Nicias, and Alcibiades, plus Xenophon’s Memorabilia and Symposium, plus Lysias’s speeches and some of Diogenes Laertius Book 2 on Socrates.

title: Family or Faction? The Political, Social and Familial Networks Discerned from Cicero's Letters during the Civil War between Caesar and Pompey
Creators: name: Gilles, Gregory
Publisher: name: Journal of Historical Network Research
Year: 2020

description: The civil war between Caesar and Pompey has inevitably been categorised as the downfall of the Roman Republic. It eventually affected every Roman citizen and would ultimately shape the course of events that led to the creation of the first principate. Although this struggle for power has been well documented, and argued from various political angles, relatively few classicists have debated the affiliations and/or support that these two aspiring autocrats would have needed in order to secure victory. The aim of this paper is to highlight these lesser discussed affiliations by using social network analysis (SNA) to scrutinise Cicero’s letters in order to map the connections between Roman senators at the time of the civil war.

'Doing love' online : performative gender and the urban everyday
Creators: name: Schoemaker Holmes, Jacqueline
Publisher: name: University of British Columbia
Year: 2010

description: While much has been said about the role of online dating in transforming the nature of intimate relationships and love in Canada and beyond (Bauman, 2003; Ben-Ze'ev, 2004; Brym and Lenton, 2001) there has been no systematic study of the pursuit of hetero-romantic love online as a practice of both the everyday and of gendered selfing. In January 2007, I began an eight-month investigation into the everyday practices of urban professionals online dating in Vancouver, Canada to study what role new media play in producing particular kinds of gendered selves through the pursuit of love online. By engaging with critical readings of feminist theories to explore the ways love has evolved as a theoretical concept and an enduring, increasingly technologically-mediated social practice, I forward the concept of 'doing love' as a contemporary way individuals perform gender online. I argue that the pursuit of hetero-romantic love, that is, 'doing love' online, is a contemporary gendered selfing project that is both individualized and routinized as part of a larger gendered discursive field that seeks to position heterosexuality, as tied to hetero-romantic love, as natural, necessary, and inevitable. Gendered selfing, through the pursuit of hetero-romantic love, requires coherence and approval by others and is in this sense policed. I demonstrate how this policing is apparent in the online dating practices of my participants which include filtering, fat phobia and fat authenticity, the management of inappropriate aphrodisia, and contingent constructions of properly made 'homes' as the outcome or triumph of heterosexual online dating pursuits. Gender emerges in this study as a by-product of the regulatory force of constitutive hetero-romantic love pursuits that necessitate appropriately gendered bodies and being deemed suitable for heterosexual coupling. By exploring love as a performative and orienting force that is uniquely articulated through the performance of gender online, this study enriches understandings of gendered practices of selfing, as realized through engagement with new media. It thus illustrates the enduring and persistent nature of gender as an organizing, and at times oppressive, force in our everyday lives.
title: The Pompeian Connection. A Social Network Approach to Elites and Sub-Elites in the Bay of Naples
Creators: name: Broekaert, Wim
Publisher: name: Journal of Historical Network Research
Year: 2020

description: This paper focuses on the composition and interaction of Pompeian elite and sub-elite networks and the way in which these relationships shaped and transformed local politics. SNA can contribute to the ongoing debate on the composition and alleged stability or turnover within the Pompeian aristocracy. This dispute has a long tradition and the picture of the Pompeian society emerging oscillates between a democratic community with high levels of social and political mobility and a more traditional Roman city with well-established families dominating the political scene and newcomers rising and disappearing in the margin. I shall analyze and compare the different networks members of elites and sub-elites were circulating in and how they attempted to use, share, extend and manipulate networks to achieve their goals. The key to power thus lies in moving oneself in the most interesting position in the network, either through mobilizing inherited connections, power and wealth or carving out a new location by means of personal assets. The following sections will show how Pompeian elites, established families and newcomers alike, tried to find the most valuable position in the local network and consequently captured the inherent benefits of connectivity.

description: The production of word stress in a second language (L2) is one area of difficulty for language learners. Previous studies have shown that correct word stress may be more important for the comprehensibility of non-native speech than grammatical accuracy. Studies indicate that incorrect stress patterns in an L2 are mainly due to transfer from learners’ first language (L1). This thesis examines the effect of training on the ability of English native speakers who are beginner-level learners of German to produce stress patterns in words from three distinct categories: native German words; German-English cognate words; and words with unstressed suffixes. The results reveal that training improves learners’ production of German word stress and raises learners’ awareness. Participants were more accurate in their production of native German words and those with unstressed suffixes than they were in their production of cognates. The results have implications for vocabulary teaching in L2 classrooms.

description: In the framework of constituent quark model, the effect of hidden color channels on the nucleon-nucleon ($NN$) interaction is studied. By adjusting the color confinement strength between the hidden color channels and color singlet channels and/or between the hidden color channels and hidden color channels, the experimental data of $S$ to $I$ partial-wave phase shifts of $NN$ scattering can be fitted well. The results show that the hidden color channel coupling might be important in producing the intermediate-range attraction of $NN$ interaction. The deuteron properties and dibaryon candidates have also been studied with this model.

description: The issue of protecting and propagating traditional music has been paid extraordinary attention by Western musicians since the nineteenth century. In 1998, Yo-yo Ma established the Silk Road Project, a nonprofit foundation devoted to the living arts of people from the various cultures found on the historical Silk Road. In this project, many pieces of tradition music from these cultures have been transformed in new ways, allowing them to be performed and propagated among the diverse audiences of today’s multicultural context. This study aims to examine how Ambush from Ten Sides, a masterpiece of Chinese traditional music, was arranged and presented by the Silk Road Ensemble. My work will focus primarily on two issues: 1) What methods did the Silk Road Ensemble use to adapt this piece of traditional music; and 2) How do today’s audiences from both the West and the East receive and understand the adaptation? In our present context, I believe that preserving traditional music in its original form will not satisfy audiences. Innovating traditional practice without losing its original essence is the approach that I advocate. Through analyzing the music and interviewing the audience members from both China and North America, I will show that Yo-yo Ma’s Silk Road Project has been successful in doing this, and, as a result has contributed to the promotion of Chinese traditional music in North America. The innovative aspects of the adaptation of Ambush from Ten Sides by the Silk Road Project are intended to facilitate Western musical acceptation of this piece. However, as opposed to most Western composers in the twentieth-century who used Chinese musical materials to create works that serve as vehicles for self-expression, the Silk Road Project attempts to capture and transmit the cultural artefact (Ambush from Ten Sides) from one culture to another. To achieve this cultural transmission, the arrangers adopted three strategies in preparing the adaptation of Ambush from Ten Sides: 1) the breaking of tradition, 2) the mixing of elements from different cultures and 3) the weakening of a sense of the exotic (from the perspective of North American audiences).

description: For Roman emperors, loyal advisors in their immediate vicinity were an absolute necessity to ensure good governance. This was the role played by L. Aelius Seianus for emperor Tiberius. Seianus’ exemplary career and climb on the social ladder hit its peak in A.D. 31, when he held the consulship together with Tiberius. A few short months later, he was executed following allegations of plotting against the emperor’s life. With his fall, the networks he had created also disintegrated. This concerned notable figures such as C. Annius Pollio, C. Appius, Iunius Silanus, Mam. Aemilius Scaurus, C. Calvisius Sabinus and L. Annius Vinicianus. This chapter examines Seianus’ networks of support and power, highlighting their dynamics and adaptability.

The specific frequencies of ultra-compact dwarf galaxies

description: We aim at quantifying the specific frequency of UCDs in a range of environments and at relating this to the frequency of globular clusters (GCs) and potential progenitor dwarf galaxies. Are the frequencies of UCDs consistent with being the bright tail of the GC luminosity function (GCLF)? We propose a definition for the specific frequency of UCDs, S_{N,UCD}=N_{UCD}*10^{0.4*(M_{V,host}-M_{V,0})}*c_{w}. The parameter M_{V,0} is the zeropoint of the definition, chosen such that the specific frequency of UCDs is the same as those of globular clusters, S_{N,GC}, if UCDs follow a simple extrapolation of the GCLF. The parameter c_{w} is a correction term for the GCLF width sigma. We apply our definition of S_{N,UCD} to results of spectroscopic UCD searches in the Fornax, Hydra and Centaurus galaxy clusters, two Hickson Compact Groups, and the Local Group. This includes a large database of 180 confirmed UCDs in Fornax. We find that the specific frequencies derived for UCDs match those of GCs very well, to within 10-50%. The ratio {S_{N,UCD}}/{S_{N,GC}} is 1.00 +- 0.44 for the four environments Fornax, Hydra, Centaurus, and Local Group, which have S_{N,GC} values. This good match also holds for individual giant galaxies in Fornax and in the Fornax intracluster-space. The error ranges of the derived UCD specific frequencies in the various environments then imply that not more than 50% of UCDs were formed from dwarf galaxies. We show that such a scenario would require >90% of primordial dwarfs in galaxy cluster centers (<100 kpc) to have been stripped of their stars. We conclude that the number counts of UCDs are fully consistent with them being the bright tail of the GC population. From a statistical point of view there is no need to invoke an additional formation channel.

"Rendezvous" for renewal at "Lake of the Great Spirit": the french pilgrimage and indigenous journey to Lac Ste. Anne, Alberta, 1870-1896

description: The Lac Ste-Anne Pilgrimage is an Indigenous-Catholic gathering that takes place along the lake at Lac Ste-Anne, Alberta, seventy-five kilometres west of Edmonton, and continues to attract approximately 50, 000 pilgrims yearly, most of them of First Nations or Métis heritage. It was initiated on June 6, 1889, by Jean-Marie Lestanc, a Catholic father with the Oblates of Mary Immaculate, a congregation which originated in Marseilles, France. This thesis discusses the long history of both Catholic pilgrimage and aboriginal rendezvous traditions in France and Canada respectively, and addresses the complexity of conversion among North-Western Canadian indigenous peoples in the nineteenth century. It suggests that the event was borne of an implicit negotiation and compromise between the largely francophone Oblate fathers and the local First Nations and Métis peoples over the significance of Lac Ste-Anne, and the “nomadic” ritual journey needed to arrive there.
Becoming BlackWomanTeacher: an autoethnographic illumination of teacher leadership development for critical democratic public education in Newark, NJ
Creators: name: Owens, Leah Z.
Publisher: name: No Publisher Supplied
Year: 2020

description: The author is an urban high school teacher turned doctoral student whose exposure to critical theory and pedagogy compelled her to new action and wonderings. She wonders about the relationship among democracy and education and racism. She wonders how teacher leaders are prepared to become politically active in the contemporary neoliberal context. This experimental inquiry is located within a post qualitative paradigm. The author thinks with theory as she narrates and analyzes her lived experiences of being re-constituted into a teacher leader committed to critical democratic public education (auto). This autoethnographic inquiry illuminates and critically analyzes (graphy) the intersections of democracy and racism with urban education reform and the practices of teacher leadership (ethno). The author uses critical race theory, critical democratic theory, and Black feminist thought to analyze this journey that takes place in Newark, New Jersey from 2004 to 2018. During this time, neoliberal education reform initiatives emerge in force and begin to dominate the educational landscape in Newark, subsequently leading to an uprising of the community who fight back against neoliberalism’s deceitful apolitical nature while envisioning critical democratic public schools. This dissertation is written using the three article format. Three separate, publication-ready manuscripts represent the findings of this inquiry. These findings illuminate some of what may be missing in teacher preparation, namely how adopting a womanist pedagogical approach can cultivate social justice educators and how field experiences crafted from a critical perspective can provide opportunities for preservice teachers to practice place-based political activism and develop their teacher leadership.

description: We present a summary of Swift and Suzaku X-ray observations of the 2010 nova outburst of the symbiotic star, V407 Cyg. The Suzaku spectrum obtained on day 30 indicates the presence of the supersoft component from the white dwarf surface, as well as optically thin component from the shock between the nova ejecta and the Mira wind. The Swift observations then allow us to track the evolution of both components from day 4 to day 150. Most notable is the sudden brightening of the optically thin component around day 20. We identify this as the time when the blast wave reached the immediate vicinity of the photosphere of the Mira. We have developed a simple model of the blast wave-wind interaction that can reproduce the gross features of the X-ray evolution of V407 Cyg, and explore a parameter space of ejected mass, binary separation and Mira mass loss rate. If the model is correct, the binary separation is likely to be larger then previously suggested and the mass loss rate of the Mira is likely to be relatively low.

description: Living during the heyday of the Roman Empire, the senator Pliny the Younger (ca. AD 61/62 – 113/114) was in contact with the social and political elite of his time: several Emperors, fellow senators like Cornelius Tacitus, Sosius Senecio, and Arulenus Rusticus, as well as other well-known figures of his time such as Suetonius Tranquillus and Valerius Martialis were part of Pliny's social network in Rome and his native Transpadana. Letters were a main means of staying in contact. Considering the multi-faceted ties of amicitia, ranging from family ties to friendship and patronage, this chapter endeavors to analyze the Epistulae of Pliny, trying to reconstruct cases where Pliny and/or his associates use their own political and social weight to build political alliances in order to procure positions for themselves and their amici. Social network analysis helps to identify clients, brokers, and patrons not only in each particular situation but in Pliny's network as a whole, showing who helped whom and the reasons and means how they did it.

description: Phase diagram of an Ising-spin Kondo lattice model on a triangular lattice near 1/3-filling is investigated by Monte Carlo simulation. We identify a partially disordered phase with coexistence of magnetic order and paramagnetic moments, which was unstable in two-dimensional Ising models with localized spins only. The partial disorder emerges in the competing regime between a twosublattice stripe phase and three-sublattice ferrimagnetic phase, at finite temperatures above an electronic phase separation. The peculiar magnetic structure accompanies a charge order and develops a gap in the electronic structure. The results manifest a crucial role of the nonperturbative interplay between spin and charge degrees of freedom in stabilizing the partial disorder.

description: The coherent potential approximation has historically allowed the efficient study of disorder effects over a variety of solid state systems. Its original formulation is however limited to a single-site or uncorrelated model of local substitutions. This neglects the effects of correlation and short range ordering, often found in realistic materials. Recent theoretical work has shown how to systematically address such shortcomings, for simple materials with only one element per unit cell. We briefly review the basic ideas of these developments within the framework of multiple scattering theory, and suggest their generalization to materials with complex lattices and possibly different types of disorder. We illustrate this extension with an example of local environment effects in the exotic Hapkeite $Fe-Fe_{37.5%}Si_{62.5%}$ compound.

description: Celiac disease (CD) is an autoimmune disorder that is triggered by the incomplete digestion of gliadins in dietary gluten due to the abundance of P and Q residues in their protein sequence(s). This thesis provides an initial assessment of the proteolytic activity of Nepenthes plant extracts, which is attributed to the aspartic proteases, nepenthesin I and II, potential as an oral protease therapeutic for CD. To this end, nepenthesin I and II were produced recombinantly and characterized. The recombinant nepenthesins were able to reconstitute the proteolytic activity of Nepenthes extracts except for cleavage after P, which was attributed to a previously unidentified protease. Nevertheless, the Nepenthes extracts and recombinant nepenthesin I/II were assessed for their capacity to detoxify gliadins. Although the recombinant nepenthesins alone did not appear sufficient, the Nepenthes plant extracts appeared to efficiently detoxify gliadin, which supports the proposed formulations potential as an effective oral therapeutic for CD.

description: Wim Broekaert, Elena Köstner, Christian Rollinger (eds.) During the last decade, the field of ancient history and classics has witnessed a slow but steady increase of publications applying to Greco-Roman history the concepts of social network analysis (SNA). While initially mainly introducing the concept of networks and connectivity in a metaphorical sense, recent research increasingly turned to the more quantitative aspects of network analysis. It is therefore quite remarkable that few attempts have been made to apply the tools of formal network analysis to a research topic ideally suited for this particular approach, viz. Greco-Roman politics. Literary sources, inscriptions and papyri offer a wealth of information on municipal and imperial elites, careers, selection procedures, and most importantly, the ties of family, marriage, friendship, patronage, and bribery that connected them. As the case studies in this special, guest-edited issue of The Journal of Historical Network Research show, SNA promises to offer new perspectives on a research field mainly dominated by more traditional prosopographical studies and at the same time provide a powerful tool for analyzing and visualizing social and political connections in ancient societies.

An examination of attentional training in dysphoric and non-dysphoric individuals
Creators: name: Mastikhina, Liza
Publisher: name: Graduate Studies

Subjects: subject: Psychology--Clinical
subject: Attentional Bias
subject: Depression
subject: information processing
subject: cognition
subject: emotion

description: The present study examined the longitudinal effects of attentional retraining on symptoms of depression. It was a replication and extension of an earlier study by Wells & Beevers (2010). Based on their baseline BDI scores, undergraduate psychology students were randomly assigned into one of 4 groups. Dysphoric participants were assigned into either the neutral training or the control condition. Non-dysphoric participants were assigned into either the dysphoric training or the control condition. All dysphoric participants showed a significant reduction in depressive symptoms throughout the study, F(2, 73.55) = 21.88, p<.001; however, no group differences were observed. The hypothesis that negative bias retraining condition would induce depressive symptoms from baseline to follow-up was not confirmed. Results were inconsistent with those of Wells and Beevers’ (2010). Implications of the findings on research on attentional retraining in the context of depression are discussed.
title: Quintus Cicero and Roman Rule. Networks between Centre and Periphery
Creators: name: Vogel, Christian
Publisher: name: Journal of Historical Network Research
Year: 2020

description: This chapter analyses the governorship of Quintus Tullius Cicero (102[?]-43 BCE) during his three year-long administration of the province of Asia from 61 to 58 BCE and during his command of a Roman legion under Caesar in Gaul in 54 BCE. Both commands represent different stages and situations of Roman rule over different regions and cultures. The relationship between rulers and ruled, between governors and governed peoples, will be studies by means of SNA. The chapter will examine Quintus’ networks in Gaul and in Asia and situate them within the larger sphere of Roman government. It will also discuss the benefits and obstacles that historical network research has to face in these examples and present considerations to provide grounds for more general reflections on the application of SNA in Greco-Roman history, especially regarding structures of control and empires.

Electrostrictive fluid pressure from a laser beam

description: Recent times have seen surge of research activity on systems combining fluid mechanics and electromagnetic fields. In radiation optics, whenever information about the distribution of pressure in a dielectric fluid is required, the contribution from electrostriction becomes important. In the present paper we calculate how the local pressure varies with position and time when a laser beam is imposed in a uniform fluid. A Gaussian intensity profile of arbitrary time dependence is assumed for the beam, and general results are derived in this case. For demonstration we analyze two different cases: first, that the beam is imposed suddenly (mathematically in the form of a step function); secondly, that the beam is switched on in a soft way. In both cases, simple analytical expressions for the pressure distribution are found.

description: Viscoelastic description of the electron subsystem of a semi-bounded metal on the basis of the generalized "jellium" model using the method of nonequilibrium statistical Zubarev operator is proposed. The nonequilibrium statistical operator and the quasi-equilibrium partition function calculated by means of the functional integration method are obtained. Transport equations for nonequilibrium mean values of electron density and momentum are received in the Gaussian approximation and in the following higher approximation that corresponds to the third-order cumulant averages in calculation of the quasi-equilibrium partition function.

Self-organized criticality in boson clouds around black holes

description: Boson clouds around black holes exhibit interesting physical phenomena through the Penrose process of superradiance, leading to black hole spin-down. Axionic clouds are of particular interest, since the axion Compton wavelength could be comparable to the Schwarzschild radius, leading to the formation of "gravitational atoms" with a black hole nucleus. These clouds collapse under certain conditions, leading to a "Bosenova". We model the dynamics of such unstable boson clouds by a simple cellular automaton and show that it exhibits self-organized criticality. Our results suggest that the evolution through the black hole Regge plane is due to self-organized criticality.
title: Informal Political Communication and Network Theory in the Late Roman Republic
Creators: name: Rosillo-López, Cristina
Publisher: name: Journal of Historical Network Research

description: This paper aims at analysing informal conversations between senators during the Late Roman Republic through the lens of network theory in order to discern strategies to look for and circulate information. Elite informal conversations (frequently defined as sermo by the sources) were an everyday event in politics and went beyond relationships of amicitia or friendship. Informal exchanges framed the way in which political deals were made, opinions were tentatively questioned, news circulated, and Roman senators looked for information, exactly as described by the Latin verb expiscor, which expresses the same metaphor as the modern expression “to angle (or fish) for information”. I shall analyse such informal conversations through social network analysis (SNA) looking for relevant nodes, liaisons and relevant information channels, in order to understand how such informal conversations worked as an informal part of the political system.

The Impact of Local Socio-Cultural Norms and Economic Needs on Curricula and Teaching Practices: A Study of a Western Branch Campus Located in a Host Country
Creators: name: Copeland, Alan
Publisher: name: Graduate Studies
Year: 2014
Subjects: subject: Education--Curriculum and Instruction
subject: international education
subject: branch campus
subject: teaching and curricula practices

description: This dissertation considered issues related to the operation of Western Branch Campuses in host countries which is a discourse within the literature on international education. The research question explored the extent to which local socio-cultural norms and economic needs inform curricula and teaching practices at a Western branch campus located in a host country in the Arabian Gulf region. The research question was examined through the methodology of a qualitative case study. A triangular research design examined relevant data from multiple sources and multiple perspectives using the methods of documentary analysis and textual analysis. Participants in the study were instructors, administrators, and students who attended, or worked at, the Western branch campus of a North American post-secondary institution in the Arabian Gulf region. While curricula practice is controlled by the home institution, the branch campus can recommend changes to program structures and course outlines. The study found that although the socio-cultural norms of the host country do not inform curricula practice at the home institution, most instructors at the branch campus independently modify their teaching practice to suit the socio-cultural norms, learning needs, and English proficiency levels of their students. Moreover, the economic needs of the host country are beginning to inform curricula practice at the home institution as evidenced by the creation of unique programs and courses at the branch campus, and by the approval of minor modifications to some course outlines in those programs offered at both the home institution and the branch campus.
