description: The Indo-Burman mountain rangesmarkthe boundary between the Indian and Eurasian plates, north of the Sumatra–Andaman subduction zone. Whether subduction still occurs along this subaerial section of the plate boundary, with 46mm/yr of highly oblique motion, is contentious. About 21mm/yr of shear motion is taken up along the Sagaing Fault, on the eastern margin of the deformation zone. It has been suggested that the remainder of the relative motion is taken up largely or entirely by horizontal strike-slip faulting and that subduction has stopped. Here we present GPS measurements of plate motions in Bangladesh, combined with measurements from Myanmar and northeast India, taking advantage of a more than 300 km subaerial accretionary prism spanning the Indo-Burman Ranges to the Ganges–Brahmaputra Delta. They reveal 13–17mm/yr of plate convergence on an active, shallowly dipping and locked megathrust fault. Most of the strike-slip motion occurs on a few steep faults, consistent with patterns of strain partitioning in subduction zones. Our results strongly suggest that subduction in this region is active, despite the highly oblique plate motion and thick sediments. We suggest that the presence of a locked megathrust plate boundary represents an underappreciated hazard in one of the most densely populated regions of the world.

description: We investigate the finite-temperature properties of attractive three-component (colors) fermionic atoms in optical lattices using a self-energy functional approach. As the strength of the attractive interaction increases in the low-temperature region, we observe a second-order transition from a Fermi liquid to a color superfluid (CSF), where atoms from two of the three colors form Cooper pairs. In the strong attractive region, we observe a first-order transition from a CSF to a trionic state, where three atoms with different colors form singlet bound states. A crossover between a Fermi liquid and a trionic state is observed in the high-temperature region. We present a phase diagram covering zero to finite temperatures. We demonstrate that the CSF transition temperature is enhanced by the anisotropy of the attractive interaction.

Aldous Huxley in evolution : the novels 1921-1935
Creators: name: Hallam, MJ
Publisher: name: University Of Tasmania
Year: 2023

description: This study argues that the novels of Aldous Huxley written 1921-1939 reflect the influence of Charles Darwin's The Origin of Species on the loss of faith and decline of traditional spiritual values representative of those times. An introduction places Huxley, his work and ideas, against the background of the late 19th century literary and scientific scene. It examines his position as a writer of popularity and influence in the years between the World Wars, in relation to his struggle to achieve a new perspective and sense of value. It also places Huxley in a critical context, suggesting that, while the decline in his literary reputation over the past 40 years reflects his weaknesses as a writer, his contribution to 20th century literature's revaluation of the role of man in an evolving universe, although generally overlooked, is significant. The first chapter looks at the ways in which Huxley's first two novels, Crome Yellow (1921) and Antic Hay (1923), express his growing sense of the social and spiritual isolation of the individual in an evolving world, a world described by Darwin as 'an inextricable web of affinities'. This sense is brought about by his perception of the inadequacy of viewing the world in the traditional way, as a hierarchical ordering of creation with man at the apex, in God's image. The second chapter pursues this sense of isolation to its most extreme expression, the fear of death, found in the novels of the late twenties, Those Barren Leaves (1925) and Point Counter Point (1928). This fear, part of Huxley's rejection of the physical basis of human existence, is related to Darwin's influence on contemporary assumptions about mortality and change. It is seen to lead to a bleak and despairing interpretation of mankind's nature and destiny. Huxley's sense of the irreconcilable divisions in human existence is suggested to be a reflection of his divided sense of self: from it sprang a spiritual and philosophical impasse from which no positive or developing theme could emerge. The third chapter examines the ways in which this impasse was gradually resolved in the novels of the thirties, Brave New World (1931) and Eyeless in Gaza (1935). A more positive outlook is seen to correspond to a growing acceptance of self as a physical and emotional being, as well as a rational and spiritual one. Darwin's unifying vision of the universe, and the optimism he expressed with his interpretation of evolution as 'progress towards perfection; are incorporated into Huxley's mature outlook. A sense of an inherent division in human existence remains, but is able to be placed in a wider perspective of universal harmony.

Ocean-atmosphere interaction

description: The Bay of Bengal, subjected to monsoonal forcing and tropical cyclones, displays a complex field of ocean eddies. On 5 December 2013 a sub-surface vortex or Intrathermocline Eddy (ITE) composed of water characteristic of the Andaman Sea was observed within the thermocline of the western Bay of Bengal. We propose that the ITE was the product of Tropical Cyclone Lehar interaction on 27 November 2013 with a westward propagating surface eddy from the eastern Bay of Bengal. While Lehar’s interaction with the ocean initially removes heat from the upper layers of the eddy, air-sea flux is limited as the deeper portions of the eddy was subducted into the stratified thermocline, inhibiting further interaction with the atmosphere. The ITE core from 30 to 150m is thus isolated from local air-sea fluxes by strong stratification at the mixed layer base, and its periphery is stable to shear instability, suggestive of longevity and the ability to carry water far distances with minimal modification.
Final Performance Report: Preservation Microfilming Project: Slavic Culture and History, Phase IV
Creators: name: Gertz, Janet Elaine
Publisher: name: Columbia University
Year: 2007
Subjects: Library science

description: The Slavic Culture and History Project was designed to preserve Columbia's exceptionally rich Slavic collections. These materials had been identified in CUL's preservation master plan as an extremely high priority because of their importance to researchers both locally and nationally, and because the often extreme embrittlement and poor physical condition of large portions of the collection placed them at risk of imminent loss. Selected from the printed holdings of the Rare Book and Manuscript Library and from the history and humanities general collections in Butler Library, many of these titles are not widely held or are held uniquely by Columbia. Thanks to the generous support of the Endowment, this seven-year long project has achieved remarkable success. A total of 14,294 pamphlet and monograph volumes and 7,132 serial volumes have been preserved, catalog records for all of the titles filmed have been added to the national databases, and these materials have been made available for the use of current and future humanities scholars.
Laboratory studies of the effect of soil impedance and soil moisture on root elongation of seedlings of Pinus radiata D.Don.
Creators: name: Davis, G. R.
Publisher: name: University Of Tasmania
Year: 2023

description: In a drying soil root elongation rate often declines. Whether the reduction in elongation is due to reduced soil moisture or increased soil strength is disputed. The objectives of this study were to develop an empirical model of radiata pine root elongation and to determine the relative importance of soil strength and soil moisture content on root elongation, and further, to quantify the parameters of a net-pressure mechanistic model of root elongation for pine and to compare the values with those observed for a more commonly studied crop (peas). The empirical model showed seedling root elongation to be three times more sensitive to increased soil strength than to decreased soil moisture content. The observed pattern of root behavior could be logically explained by a concept of total external stress, where total external stress was a summation of soil moisture potential and an index of penetrometer resistance. Measurement of pine root segment osmotic potential gave values for cell threshold pressure (below which no elongation takes place) and cell wall elasticity consistent with values reported in the literature for other crops. The response of pine and pea seedlings to moisture stress in the absence of soil restraint was recorded. Although root elongation of both species declined as moisture potential decreased, pine seedlings showed no osmotic adjustment to moisture potential and consequently cell turgor decreased as root elongation declined. However, for peas, turgor was maintained but the correlation between turgor and elongation was poor, suggesting that the decline in elongation was due to increased threshold pressure or decreased cell wall elasticity. Measurement of pea root potential, after seedling growth in pots packed with soil of known penetrometer resistance and moisture potential, showed 11% osmotic adjustment to soil restraint and 41% adjustment to moisture potential. The data was consistent with the empirical data for radiata pine root elongation. Root behavior, on growing into a more compact soil layer, was consistent with a net-pressure model of root elongation when studied in situ using a neutron radiography technique. The technique was refined to allow a greater number of exposures for a given reactor run. Soil strength can be considered a general influence on radiata pine root growth except where extremes of soil moisture exist. Any increase in soil strength may reduce the ability of the root to tolerate moisture stress. The general influence of soil impedance on root growth and the slow recovery of some soils after compaction, suggests a better understanding of the likely effects of forest operations on soil strength is needed if productivity losses following harvesting are to be minimized.

description: This past decade has witnessed an explosive rise in the controversial diagnosis of pediatric bipolar and the prescription of anti-psychotics to children. Has the behavior of American children grown more irritable and defiant, or has adult judgment of their behavior changed? How can we effectively study and explain these dramatic transformations in judgment and behavior? This article proposes a hypothesis that explains many of these developments and lays out a research program for a continuing investigation of these urgent questions. The paper highlights the controversy around the diagnosis of pediatric bipolar and the emerging relations between the media of surveillance and structures of social control. It explores connections between the interactive media landscapes inhabited by youth, the behavioral expectations imposed on them in schools, and the role of psychoactive drugs in mediating this tension. Finally, the article details the intersections between media, communications, and madness studies and proposes a research agenda for studying this controversy using approaches drawn from these disciplines.

description: The axisymmetric form of the hydrodynamic equations within the smoothed particle hydrodynamics (SPH) formalism is presented and checked using idealized scenarios taken from astrophysics (free fall collapse, implosion and further pulsation of a sun-like star), gas dynamics (wall heating problem, collision of two streams of gas) and inertial confinement fusion (ICF, -ablative implosion of a small capsule-). New material concerning the standard SPH formalism is given. That includes the numerical handling of those mass points which move close to the singularity axis, more accurate expressions for the artificial viscosity and the heat conduction term and an easy way to incorporate self-gravity in the simulations. The algorithm developed to compute gravity does not rely in any sort of grid, leading to a numerical scheme totally compatible with the lagrangian nature of the SPH equations.

The background, jurisdictional basis and the procedural and evidential fairness of the trial of German major war criminals, Nuremberg, 1945-1946
Creators: name: Everett, MG
Publisher: name: University Of Tasmania
Year: 2023

description: Ever since the signing of the agreement in London on 8 August 1945 by representatives of the British, French, American and Russian Governments ('London agreement'), followed by the presentation to the International Military Tribunal sitting at Berlin on 18 October 1945 of the indictment against twenty four of the most prominent German military and political leaders, and the proceedings at Nuremberg which culminated in the judgement delivered on 30 September and 1 October 1946, there has been widespread and persistent controversy among lawyers, academics, scholars, historians and others, who have found ''Nuremberg Law\ a fascinating research subject. The principal issue was and remains whether or not the trials conducted pursuant to the Charter annexed to the London Agreement had a sound jurisdictional basis. For the most part the views publicly expressed by writers on the issue have been firm and diametrically opposed. It will be submitted that much of the literature whether it expresses concurring or dissenting views with respect to the validity of 'Nuremberg Law' places too much emphasis on the judgment of the Tribunal and not enough on the three basic documents. The London Agreement and Charter were a code which prescribed provisions designed to ensure so far as it was practicable to do so a fair trial before the world of German major war criminals following the virtually undisputed acts of atrocity and inhumanity of a dimension never previously experienced. The International Military Tribunal went beyond the constituent documents and propounded a number of obiter propositions. Thereby the Tribunal itself sparked much of the controversy which the trial engendered. A further object of the study is to demonstrate that many of the critics of 'Nuremberg Law' ignored the facts that the German Reich had surrendered unconditionally to the major Allied Powers and that in reaching agreement on the terms of the London Agreement and Charter they were exercising sovereign legislative authority analogous to that of the Parliament of the state of Israel when it enacted the Nazis and Nazi Collaborators (Punishment) Law of 1950. The study also includes in as much detail as is practicable an assessment of the procedural and evidential fairness of the Nuremberg trial. The object of such an evaluation is to demonstrate from the perspective of a trial lawyer that in such an emotive criminal trial as that at Nuremberg courtroom 'atmosphere' and rulings on questions of evidence and procedure were more fundamental in ensuring a fair trial than dogmatic assertions concerning legal principles such as the ex post facto doctrine and the maxim of nullum crimen nulla poena sine leae. The basic fact will always remain that the London Agreement and Charter were paramount and binding."

description: In order to achieve a high luminosity in the electron-positron Future Circular Collider (FCC-ee), very intense multi-bunch beams with low emittances are accumulated in two separate rings and collide in two interaction regions exploiting the crab waist collision scheme. In order to preserve beam quality and to avoid collider performance degradation a careful study of beam collective effects is required. In this paper we overview impedance related coherent beam effects and instabilities potentially dangerous for FCC-ee and discuss measures and techniques for their mitigation.

Extended Friedberg Lee hidden symmetries, quark masses and CP-violation with four generations

description: Motivated in part by the several observed anomalies involving CP asymmetries of B and B_s decays, we consider the Standard Model with a 4th sequential family (SM4) which seems to offer a rather simple resolution. We initially assume T-invariance by taking the up and down-quark 4x4 mass matrix to be real. Following Friedberg and Lee (FL), we then impose a "hidden" symmetry on the unobserved ("hidden") up and down-quark SU(2) states. The hidden symmetry for four generations ensures the existence of two zero-mass eigenstates, which we take to be the (u,c) and (d,s) states in the up and down-quark sectors, respectively. Then, we simultaneously break T-invariance and the hidden symmetry by introducing two phase factors in each sector. This breaking mechanism generates the small quark masses m_u, m_c and m_d, m_s which, along with the orientation of the hidden symmetry, determine the size of CP-violation in the SM4. For illustration we choose a specific physical picture for the hidden symmetry and the breaking mechanism that reproduces the observed quark masses, mixing angles and CP-violation, and at the same time allows us to further obtain very interesting relations/predictions for the mixing angles of t and t'. For example, with this choice we get V_{td} ~ (V_{cb}/V_{cd} - V_{ts}/V_{us}) + O(λ^2) and V_{t'b} ~ V_{t'd}x(V_{cb}/V_{cd}), V_{tb'} ~ V_{t'd}x(V_{ts}/V_{us}), implying that V_{t'd} > V_{t'b},V_{tb'}. We furthermore find that the Cabibbo angle is related to the orientation of the hidden symmetry and that the key CP-violating quantity of our model at high-energies, J_{SM4} = Im[V_{tb} V_{t'b}^* V_{t'b'} V_{tb'}^*], which is the high-energy analogue of the Jarlskog invariant of the SM, is proportional to the light-quark masses and the measured CKM angles.

description: We consider the time delay of massive, non-relativistic, one-dimensional particles due to a tunneling potential. In this setting the well-known Hartman effect asserts that often the sub-ensemble of particles going through the tunnel seems to cross the tunnel region instantaneously. An obstacle to the utilization of this effect for getting faster signals is the exponential damping by the tunnel, so there seems to be a trade-off between speedup and intensity. In this paper we prove that this trade-off is never in favor of faster signals: the probability for a signal to reach its destination before some deadline is always reduced by the tunnel, for arbitrary incoming states, arbitrary positive and compactly supported tunnel potentials, and arbitrary detectors. More specifically, we show this for several different ways to define ``the same incoming state'' and ''the same detector'' when comparing the settings with and without tunnel potential. The arrival time measurements are expressed in the time-covariant approach, but we also allow the detection to be a localization measurement at a later time.

Mitigation of coherent beam instabilities (MCBI) for CERN LIU and HL-LHC
Creators: name: Rumolo, G.
Publisher: name: CERN Yellow Reports: Conference Proceedings
Year: 2020

description: The high-luminosity upgrade of the Large Hadron Collider (HL-LHC) will meet its future yearly integrated luminosity target by means of performance improving upgrades of the LHC itself as well as by receiving significantly higher beam current and brightness from its injectors. The implications of the pushed beam parameters are twofold. On one side, all the accelerators of the LHC injection chain will have to be upgraded to produce the desired beam parameters. For this purpose, the LHC Injectors Upgrade (LIU) program has been established to implement all the needed modifications for meeting the required beam specifications. These upgrades will target the mitigation of coherent beam instabilities and space charge in the injectors, which will allow lifting their existing intensity and brightness limitations to the desired extent. On the other side, the LHC will have to be able to accept the new beam parameters and exploit them at best to produce the integrated luminosity target. This will mainly require control of impedance driven instabilities, beam-beam effects and electron cloud in the LHC itself. In this paper, we will focus on proton beams by describing the identified performance limitations of the LHC and its injectors, as well as the actions envisioned to overcome them.

Noise and possible loss of Landau damping through noise excited wakefields
Creators: name: Furuseth, S.V.
name: Buffat, X.
Publisher: name: CERN Yellow Reports: Conference Proceedings
Year: 2020

description: The effect of transverse Landau damping in circular hadron colliders depends strongly on the bunch distribution. The bunches are often assumed to be Gaussian in the transverse dimensions, as it fits well to measurements and it is the expected effect of intra-beam scattering. However, a small change of the distribution can cause a loss of stability. We study the effect that external noise excites the transverse motion of the beam, which produces wakefields, which act back on the beam and cause a diffusion of incoherent particles. The diffusion is narrow in frequency space, and thus also in action space. Macroparticle simulations have shown a similar change of the distribution, which is only detectable in action space, not projected in position space. The narrow diffusion efficiently drills a hole in the stability diagram, at the location of the unstable mode, eventually leading to an instability. The advised mitigation technique is to reduce the drilling rate by operating with a stability margin.

description: During the operation of the Large Hadron Collider in 2018, the majority of physics data was collected with a beam energy of 6.5 TeV, a bunch spacing of 25 ns and with β-functions in the high luminosity interaction points equal to 30 cm. In this configuration, it was found through several experimental measurements that electron cloud induces a significant degradation of the beam lifetime. This contribution reviews the available experimental observations, showing in particular the role played by the e-cloud located in regions around the interaction points, where the two beams share the same vacuum chamber. Recent developments toward a reliable numerical simulation of these incoherent effects driven by electron cloud are also presented.

description: Constraining how much and how fast the West Antarctic Ice Sheet (WAIS) will change in the coming decades has recently been identified as the highest priority in Antarctic research (National Academies, 2015). Here we review recent research on WAIS and outline further scientific objectives for the area now identified as the most likely to undergo near-term significant change: Thwaites Glacier and the adjacent Amundsen Sea. Multiple lines of evidence point to an ongoing rapid loss of ice in this region in response to changing atmospheric and oceanic conditions. Models of the ice sheet's dynamic behavior indicate a potential for greatly accelerated ice loss as ocean-driven melting at the Thwaites Glacier grounding zone and nearby areas leads to thinning, faster flow, and retreat. A complete retreat of the Thwaites Glacier basin would raise global sea level by more than three meters by entraining ice from adjacent catchments. This scenario could occur over the next few centuries, and faster ice loss could occur through processes omitted from most ice flow models such as hydrofracture and ice cliff failure, which have been observed in recent rapid ice retreats elsewhere. Increased basal melt at the grounding zone and increased potential for hydrofracture due to enhanced surface melt could initiate a more rapid collapse of Thwaites Glacier within the next few decades.

description: In three spatial dimensions, in the unitary limit of a non-relativistic quantum Bose or Fermi gas, the scattering length diverges. This occurs at a renormalization group fixed point, thus these systems present interesting examples of interacting scale-invariant models with dynamical exponent z=2. We study this problem in two and three spatial dimensions using the S-matrix based approach to the thermodynamics we recently developed. It is well suited to the unitary limit where the S-matrix equals -1, since it allows an expansion in the inverse coupling. We define a meaningful scale-invariant, unitary limit in two spatial dimensions, where again the scattering length diverges. In the two-dimensional case, the integral equation for the pseudo-energy becomes transcendentally algebraic, and we can easily compute the various universal scaling functions as a function of μ/T, such as the energy per particle. The ratio of the shear viscosity to the entropy density is above the conjectured lower bound of for all cases except attractive bosons. For attractive 2-component fermions, the ratio is greater than 6.07 times the conjectured lower bound, whereas for attractive bosons it is greater than 0.4 times it.

Coupled bunch and fast head-tail instabilities caused by an electron cloud have been studied for a long time, and the agreement of experiments and simulations/theory is almost perfect in positron storage rings. Mitigation of the instabilities based on the experiments and simulations have improved the accelerator performance drastically. It is essential to mitigate the instabilities in the present and future positron and proton rings.

All the finite-size vanadium-borazine systems are found to be ferromagnetically stabilized, with the infinite one-dimensional wire exhibiting robust half-metallic behaviour. The finite-size clusters are also found to exhibit efficient spin filter properties when coupled to graphene electrodes.
Some size and structure theorems for ultrapowers
Creators: name: Jorgensen, Murray Allan
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis we study the mapping D → A[sup I]/D, between ultrafilters and models, given by the ultrapower construction. Under this mapping homomorphisms of ultrapowers induce elementary embeddings of ultrapowers. Using these embeddings we investigate the dependence of the structure of an ultrapower A[sup I]/D on the cardinality of the index set I. With each ultrafilter D we associate a set of cardinals a(D) which we term the shadow of D. We investigate the form of the sets a(D). It is shown that if σ(D) has "gaps" then isomorphisms arise between ultrapowers of different index sizes. In terms of σ(D) we prove new results on the properties of the set of homomorphic images of an ultrafilter. Finally we introduce a new class of "quasicomplete" ultrafilters and prove several results about ultrapowers constructed using these. Two results which can be mentioned here are the following: Let α be a regular cardinal. We establish necessary and sufficient conditions on D (i) for the cardinality of α to be raised in the passage to α[sup I]/D. (ii) for the confinality of α[sup I]/D (regarded as an ordered set) to be greater than α⁺. Some of the results of this thesis depend on assumption of the Generalised Continuum Hypothesis. The result (i) above is a case in point.
Cardiac [alpha] 1 receptors and their role in glucose uptake
Creators: name: Edwards, S J
Publisher: name: University Of Tasmania
Year: 2023

description: The isolated Langendorf-perfused rat heart was assessed as a model for the study of a1-adrenoceptor binding parameters and receptor coupling of a1-mediated processes, particularly control of glucose uptake. The method avoided many of the problems associated with classical disrupted tissue studies, primarily low and varying yield, and allowed the relationship between binding and efficacy to be studied in the same preparation.
Accuracy of bound-state form factors extracted from dispersive sum rules

description: We discuss the extraction of form factors from three-point sum rules making use of harmonic-oscillator model, where we derive the exact expression for the relevant correlator. We determine the form factor of the ground state by the standard procedures adopted in the method of sum rules, and compare the obtained results with the known exact values. We show that the uncontrollable uncertainty in the extracted value of the form factor is typically much larger than that for the decay constant. In the example considered, we find the uncontrolled systematic error in the extracted form factor to exceed the 10% level.

Perception of trauma of childhood sexual abuse related to subsequent psychological and parental functioning in a community sample
Creators: name: Fitzgerald, Anne
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis investigated the long-term psychological and parental functioning of 31 adult women, who were sexually abused as children, and 31 controls drawn from a community sample. It used a Perceived Trauma of Abuse Scale to investigate the relationship between the actual features of the abuse experience and the subsequent perception of trauma associated with the abuse, and to divide the sexually abused subjects into a High Trauma and a Low Trauma group. A close relationship to the offender, abuse continuing over a long period, and disbelief or blame upon disclosure were most strongly correlated with high perceived trauma. The High Trauma group suffered significantly higher levels of psychological distress (withdrawal, dependence/low self esteem, anxiety, depression, borderline personality type, and alcohol abuse) and parenting stress than the Nonabused group. The psychological and parental functioning of the Low Trauma group more closely resembled that of the Nonabused group than the High Trauma group. Neither abused group differed significantly from the Nonabused group in parental attitudes, values and practices.

description: In this paper we propose new non-relativistic p+1 dimensional theory. This theory is defined in such a way that the potential term obeys the principle of detailed balance where the generating action corresponds to p-brane action. This condition ensures that the norm of the vacuum wave functional of p+1 dimensional theory is equal to the partition function of p-brane theory.

The Privileging of Visio over Vox in the Mystical Experiences of Hildegard of Bingen and Joan of Arc

description: Even though medieval women mystics have enjoyed increased attention in recent scholarly discussion, a topic that still has not been tackled is the possible difference between seeing a vision and hearing a voice during a mystical experience and the ramifications of this difference in the context of medieval text production and in the status of mystics as authors. When a mystic relates a mystical experience, she inevitably creates a text and becomes an author. In the Christian Middle Ages, medieval text creation hinged on authority and authorization, as an imitation of the creative power of God, the Master Author and the Logos (Word) itself, and thus has religious consequences for an aspiring author. Bernard McGinn points to this logocentrality of medieval writing: “Jesus the preacher of the message became Jesus the preached message and soon Jesus the written message, as elements of his preaching and the stories about him, especially the account of his sacrificial death and rising, were fixed in written form” .
Theories of interpersonal attraction : an investigation of their applicability to children's peer relations through the gender cleavage phenomenon
Creators: name: Cowles, Sharon Clare
Publisher: name: University Of Tasmania
Year: 2023

description: It is recognised that children's experiences with their peers have implication for their adjustment in later life. Much research in the area of children's peer relations has been conducted. However, studies largely have been atheoretical in nature. Existing theories of interpersonal attraction more usually applied to adult social relations appear to have some applicability to understanding children's sociometric status and friendship. The aim of this review is to examine these theories and determine their usefulness with respect to the area of children's peer relations. One clearly identified peer relations phenomenon in the literature is the gender cleavage, that is, the tendency for children to prefer same-gender as opposed to opposite-gender peers as friends. This review discusses the adequacy of two opposing theories of interpersonal attraction, specifically the Balance Theory (Heider, 1958) and the Theory of Social Exchange (Homans, 1951) in explaining gender cleavage. Although both theories may be used to explain children's peer preferences, it is not clear which is more useful in understanding children's peer relations. The review concludes that the gender cleavage phenomenon, while constituting but one aspect of children's sociometric status and friendship, may provide a useful platform from which to test the applicability of two contrasting theories of interpersonal attraction to children's peer relations.

Adiabatic dynamics in a spin-1 chain with uniaxial single-spin anisotropy

description: We study the adiabatic quantum dynamics of an anisotropic spin-1 XY chain across a second order quantum phase transition. The system is driven out of equilibrium by performing a quench on the uniaxial single-spin anisotropy, that is supposed to vary linearly in time. We show that, for sufficiently large system sizes, the excess energy after the quench admits a non trivial scaling behavior that is not predictable by standard Kibble-Zurek arguments for isolated critical points or extended critical regions. This emerges from a competing effect of many accessible low-lying excited states, inside the whole continuous line of critical points.
