description: We suggest and discuss a simple model of an ideal gas under the piston to gain an insight into the workings of the Jarzynski identity connecting the average exponential of the work over the non-equilibrium trajectories with the equilibrium free energy. We show that the Jarzynski identity is valid for our system due to the very rapid molecules belonging to the tail of the Maxwell distribution. For the most interesting extreme, when the system volume is large, while the piston is moving with large speed (compared to thermal velocity) for a very short time, the necessary number of independent experimental runs to obtain a reasonable approximation for the free energy from averaging the non-equilibrium work grows exponentially with the system size.

description: Avian influenza is a deadly disease that can spread rapidly through poultry. There are many documented cases of transmission from birds to people, but as yet only rare instances of human to human transmission. Nonetheless, public health officials are concerned about the possibility of a human pandemic, and many countries have policies of banning imports of live birds and poultry meat from infected regions. The potential impacts on Indonesia of a production shock, a shift in consumption or a trade ban are assessed using a heterogeneous product model where imports are differentiated by source. Empirical results suggest the likely trade impacts in Indonesia are minimal because its trade is a small share of production.
Host-Kra theory for $\bigoplus_{p\in P}\mathbb{F}_p$- Systems and multiple recurrence

description: Let $\mathcal{P}$ be an (unbounded) countable multiset of primes (i.e. every prime may appear multiple times) and let $G=\bigoplus_{p\in \mathcal{P}}\mathbb{F}_p$. We develop a Host-Kra structure theory for the universal characteristic factors of an ergodic $G$-system. More specifically, we generalize the main results of Bergelson Tao and Ziegler who studied these factors in the special case $\mathcal{P}=\{p,p,p,...\}$ for some fixed prime $p$. As an application we deduce a Khintchine-type recurrence theorem in the flavor of Bergelson Tao and Ziegler and Bergelson Host and Kra.

description: Shallow lakes display hysteresis in their response to phosphorous loading. Gradual increases in the nutrient content of the lake can appear to have little effect on the oligotrophic state of the lake until a point at which the lake suddenly flips to a eutrophic state. Ecotaxes on phosphorous loading have been suggested as means to maintain the lake in the socially desirable state - oligotrophic or not - when society can agree on a common welfare function. In this paper, we consider the case where society is divided into two interest groups and is thus unable to agree. In particular, the communities that share the use of the lake disagree on the relative importance of the shallow lake acting as a waste sink for phosphorous run-off as opposed to other ecosystem service. A dynamic game in which communities maximize their use of the lake results in a Nash equilibrium where the lake is in a eutrophic state when in fact the Pareto-optimum would be for the lake to be in an oligotrophic state. The tax that would induce, in a non-cooperative context, all of society's members to behave in such a way as to achieve a Pareto-optimal outcome is derived. Further, both types of communities lobby to have their preferred level of tax applied based on their relative preferences for a clean lake and phosphorous loading. The effects of the lobbying on the application of the optimal tax are investigated for particular values of relative preferences and the relative size of each group.

description: The millicharged particle has become an attractive topic to probe physics beyond the Standard Model. In direct detection experiments, the parameter space of millicharged particles can be constrained from the atomic ionization process. In this work, we develop the relativistic impulse approximation (RIA) approach, which can duel with atomic many-body effects effectively, in the atomic ionization process induced by millicharged particles. The formulation of RIA in the atomic ionization induced by millicharged particles is derived, and the numerical calculations are obtained and compared with those from free electron approximation and equivalent photon approximation. Concretely, the atomic ionizations induced by mllicharged dark matter particles and millicharged neutrinos in high-purity germanium (HPGe) and liquid xenon (LXe) detectors are carefully studied in this work. The differential cross sections, reaction event rates in HPGe and LXe detectors, and detecting sensitivities on dark matter particle and neutrino millicharge in next-generation HPGe and LXe based experiments are estimated and calculated to give a comprehensive study. Our results suggested that the next-generation experiments would improve 2-3 orders of magnitude on dark matter particle millicharge $δ_χ$ than the current best experimental bounds in direct detection experiments. Furthermore, the next-generation experiments would also improve 2-3 times on neutrino millicharge $δ_ν$ than the current experimental bounds.

description: In QCD with two light quarks with application of Bogolubov quasi-averages approach a possibility of spontaneous generation of an effective interaction, leading to the Nambu -- Jona-Lazinio model, is studied. Compensation equations for form-factor of the interaction is shown to have the non-trivial solution leading to theory with two parameters: average low-energy value of $α_s$ and dimensional parameter $f_π$. All other parameters: the current and the constituent quark masses, the quark condensate, mass of $π$ meson, mass of $σ$ meson and its width are expressed in terms of the two initial parameters in satisfactory correspondence to experimental phenomenology. The results being obtained allow to state an applicability of the approach in the low-energy hadron physics and promising possibilities of its applications to other problems.

description: Our current methods of analysing policies and the distributions of wealth insure that society is on an efficient frontier. This is not the same as a social optimum. To choose the optimal point on the frontier we need a social welfare function. Following the ordinal revolution in demand theory, a large body of research concluded that social welfare functions don't exist. The intensity of people's preferences cannot be observed and hence interpersonal comparisons are essentially impossible. This paper argues that the intensity of people's preferences can be observed and could be incorporated into a social welfare function.
Detective Stories During Apartheid: H.I.E. Dhlomo as a Precursor of Drum
Creators: name: Fossati, Marta

Year: 2021

description:

This article aims to contribute to the discussion of English-language crime fiction by black South African writers before 1994 by exploring H.I.E. Dhlomo’s relatively overlooked contribution to the genre in the first decade of apartheid. In particular, I intend to close read three detective stories written between the late 1940s and the early 1950s by Dhlomo, namely “Village Blacksmith Tragicomedy”, “Flowers”, and “Aversion to Snakes”, and compare them with the more celebrated stories published by Arthur Maimane in the popular magazine Drum a few years later. Notwithstanding their different re-elaboration of the tropes of crime fiction, I argue that both Dhlomo and Maimane resorted to this productive strand of popular literature to reassert a claim to knowledge denied to Africans, saturating their texts with new local meanings and exceeding Western genre conventions.

description: We report on the quantitative experimental illustration of elementary optomechanics within the classical regime. All measurements are performed in a commercial dilution refrigerator on a mesoscopic drumhead aluminium resonator strongly coupled to a microwave cavity, using only strict single-tone schemes. Sideband asymmetry is reported using in-cavity microwave pumping, along with noise squashing and back-action effects. Results presented in this paper are analysed within the simple classical electric circuit theory, emphasizing the analogous nature of classical features with respect to their usual quantum description. The agreement with theory is obtained with no fitting parameters. Besides, based on those results a simple method is proposed for the accurate measurement of the ratio between microwave internal losses and external coupling.

This allows us to analyze some differences between a normal fluid and a Bose-Einstein-condensed one. We show that, in close analogy with superfluid He-4, a Bose-Einstein-condensed fluid exhibits the mechanocaloric and thermomechanical effects. In our approach we can explain both effects without using the hypothesis that the Bose-Einstein-condensed fluid has zero entropy. Such ideas could be investigated in existing experiments.

description: Pyrochlore lattices, which are found in two important classes of materials -- the $A_2B_2X_7$ pyrochlore family and the $AB_2X_4$ spinel family -- are the quintessential 3-dimensional frustrated lattice architecture. While historically oxides ($X =$~O) have played the starring role in this field, the past decade has seen materials synthesis breakthroughs that have lead to the emergence of fluoride ($X =$~F) and chalcogenide ($X =$~S, Se) pyrochlore lattice materials. In this Research Update, we summarize recent progress in understanding the magnetically frustrated ground states in three families of non-oxide pyrochlore lattice materials: (i) $3d$-transition metal fluoride pyrochlores, (ii) rare earth chalcogenide spinels, and (iii) chromium chalcogenide spinels with a breathing pyrochlore lattice. We highlight how the change of anion can modify the single ion spin anisotropy due to crystal electric field effects, stabilize the incorporation of new magnetic elements, and dramatically alter the exchange pathways and thereby lead to new magnetic ground states. We also consider a range of future directions -- materials with the potential to define the next decade of research in frustrated magnetism.

description: Disordered interacting spin chains that undergo a many-body localization transition are characterized by two limiting behaviors where the dynamics are chaotic and integrable. However, the transition region between them is not fully understood yet. We propose here a possible finite-size precursor of a critical point that shows a typical finite-size scaling and distinguishes between two different dynamical phases. The kurtosis excess of the diagonal fluctuations of the full one-dimensional momentum distribution from its microcanonical average is maximum at this singular point in the paradigmatic disordered $J_1$-$J_2$ model. For system sizes accessible to exact diagonalization, both the position and the size of this maximum scale linearly with the system size. Furthermore, we show that this singular point is found at the same disorder strength at which the Thouless and the Heisenberg energies coincide. Below this point, the spectral statistics follow the universal random matrix behavior up to the Thouless energy. Above it, no traces of chaotic behavior remain, and the spectral statistics are well described by a generalized semi-Poissonian model, eventually leading to the integrable Poissonian behavior. We provide, thus, an integrated scenario for the many-body localization transition, conjecturing that the critical point in the thermodynamic limit, if it exists, should be given by this value of disorder strength.

Running In (and Out) the Family
Creators: name: Mari, Lorenzo
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The genre of the family novel can be identified in many postcolonial literary cultures. Initially, it was often read as an example of “national allegory” (Jameson 1986), thus considering family narrative in a tight relationship with postcolonial nation-building, but this theoretical framework has been later criticised from different perspectives, ranging from post-national to feminist critiques. Furthermore, the genre of the postcolonial family novel has been refashioned due to the emergence of diasporic narratives, leading to the diffusion of the “postcolonial fictions of adoption” (McLeod 2006). Nowadays, the high competition in the global literary market – namely, with family novels and sagas in the US literary market – drives this genre towards highly individualised, as well as hybridised, outcomes. While focusing, in particular, on The Brief Wondrous Life of Oscar Wao by Junot Díaz and Lara ([1997] 2009) by Bernardine Evaristo, this survey of family novels across different literary traditions aims to show the intrinsic porosity, as well as the strenuous resistance, of the genre.

Imaginations and Speculative Writings: Reinvesting Post-Colonial Possibilities and Subjectivities in Kaie Kellough’s Dominoes at the Crossroads
Creators: name: Sbih, Miriam
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

Recent studies on speculative literature emphasise the narrative presence of postcolonial thinking that proliferates within the genre. It is the case in the collection Dominoes at the Crossroads (2020) by the African Canadian writer Kaie Kellough, which attempts to re-imagine and tell the story of the black diaspora in Montreal, other than under a colonial spectrum. The short stories use a variety of speculative strategies: whether it is reinvesting a marginalised figure of a classic Quebecois novel or imagining the setting of Montreal’s future in which marginalised populations own a majority of the properties. The analysis of these stories will allow us to show how speculative literature is fertile ground for postcolonial potentialities, by allowing us to project elsewhere. Since speculative literature is a broad genre whose definition is not circumscribed, we will see how reflecting on the alternative postcolonial imaginings through such narrative allows for a rewriting that makes it possible to go beyond the colonial paradigms.

description: Non-farm rural enterprises (NFRE) are increasingly studied because of their role in poverty reduction. However, existing studies of the effects of infrastructure on NFRE may give incorrect inferences because they typically fail to account for spatial effects. Such effects could reflect either spatial errors due to excluded local effects or spatial lags due to excluded interactions, such as between households switching out of farm work. We use rural investment climate survey data from Indonesia that allow distances between each household to be measured so that spatial effects can be modeled to assess the bias from ignoring such effects.

description: Lamb carcass value is widely reported to be a function of lean meat yield, which is the relationship between muscle, fat and bone. Five retailers and five wholesalers assessed 47 lamb carcasses from diverse genotypes and scored seven attributes. A hedonic model reveals that conformation attributes were more highly valued (16 c/kg) relative to yield characteristics (4 c/kg). Meat colour and fat distribution were significant for retailers, but less important for wholesalers. Genotype was not a strong indicator of conformation. Eye muscle area and depth were correlated with Fat C; however, these were not significant. These results indicate that carcass conformation, meat colour and fat distribution should be incorporated into carcass grading models.

Going beyond linear response, we find a non-thermal distribution for f caused by an applied bias voltage. We demonstrate that the even part of f (the energy mode f_L) drives a first order transition from the superconducting state to the normal state irrespective of the current.
Caryl Phillips’s Rewriting of the Canonical Romance as a Genre
Creators: name: Polatti, Alessia
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The paper considers Phillips’s rewriting of the canonical nineteenth-century romances in three of his novels – A State of Independence (1986), The Lost Child (2015), and A View of the Empire at Sunset (2018). The three texts resettle the romance genre through the postcolonial concept of ‘home’. In A State of Independence, Phillips rearranges the role of one of Jane Austen’s most orthodox characters, the landowner Sir Thomas Bertram of Mansfield Park (1814), by transposing the Austenian character’s features to his protagonist Bertram Francis, a Caribbean man who comes back to his ancestral homeland after twenty years in Britain. In The Lost Child, chronicling literary-historical events in the present tense by transferring the life of the Brontë family into the protagonists of Wuthering Heights (1847) is for the author one way of calling into question the real sense of literature. It is for this reason that Phillips constructs a cyclic narration around the figure of Branwell Brontë, fictionalised by his sister Emily in the romance protagonist Heathcliff, and mirrored in The Lost Child in the character of Tommy Wilson. In A View of the Empire at Sunset, Phillips definitely overturns the colonial and genre categories by reassessing the in-between life of the Dominican-born writer Jean Rhys through her personal return journey to Dominica: as a result, the author of Wide Sargasso Sea (1966) (an intense rewriting of Jane Eyre) becomes a fictional character, and the literary events of her life sum up the vicissitudes both of the two ‘Bertrams’ – of Mansfield Park and A State of Independence – and the protagonists of Wuthering Heights and The Lost Child.

description: The simulation of transmission electron microscopy (TEM) images or diffraction patterns is often required to interpret their contrast and extract specimen features. This is especially true for high-resolution phase-contrast imaging of materials, but electron scattering simulations based on atomistic models are widely used in materials science and structural biology. Since electron scattering is dominated by the nuclear cores, the scattering potential is typically described by the widely applied independent atom model. This approximation is fast and fairly accurate, especially for scanning TEM (STEM) annular dark-field contrast, but it completely neglects valence bonding and its effect on the transmitting electrons. However, an emerging trend in electron microscopy is to use new instrumentation and methods to extract the maximum amount of information from each electron. This is evident in the increasing popularity of techniques such as 4D-STEM combined with ptychography in materials science, and cryogenic microcrystal electron diffraction in structural biology, where subtle differences in the scattering potential may be both measurable and contain additional insights. Thus, there is increasing interest in electron scattering simulations based on electrostatic potentials obtained from first principles, mainly via density functional theory, which was previously mainly required for holography. In this Review, we discuss the motivation and basis for these developments, survey the pioneering work that has been published thus far, and give our outlook for the future. We argue that a physically better justified $\textit{ab initio}$ description of the scattering potential is both useful and viable for an increasing number of systems, and we expect such simulations to steadily gain in popularity and importance.

description: Oversupply has posed a number of problems for the Australian wine industry in recent times. When disaggregated from the industry level, however, the problem can be better described as a range of attribute-specific disequilibria. To date, solutions to this problem have predominantly revolved around reducing output through crop thinning or vine pulling. This paper proposes a different approach by suggesting that disequilibria may be reduced by gaining a better understanding of the demand for Australian wine. A discrete choice model of product differentiation is used to estimate the demand for wine in the United States, Australia's second largest export market. Implications of the analysis are explored.

Nnedi Okorafor: traiettorie di un futurismo africano

description:

This article presents an analysis of the new category of Africanfuturism coined by the Nigerian American writer (or Naijamerican, as she defines herself) Nnedi Okorafor in 2019, after years of questions about the limits that the category of Afrofuturism has put over the receptions of her works. Okorafor felt the urgency to open this new horizon to better insist on the importance of stories and narratives profoundly rooted in the African continent, thus abandoning the Western models and canons of science fiction and creating new ways of looking towards the far future. Through the analysis of Okorafor’s novels (Who Fears Death?, Lagoon and Binti), interviews and posts on her blog, the article explores the potentialities of Okorafor’s speculative fiction to deal with technologies, traditions, cultures, social transformations, and how these issues inform a future Africa that could possibly be an entirely new world, in which the concept of ‘West’ and ‘colonialism’ do not have any meaning.

description: We present high-resolution thermal expansion $α(T)$ and magnetostriction $ΔL(H)/L$ measurements of GdMnO$_3$, which develops an incommensurate antiferromagnetic order (ICAFM) below $T_{\rm N}\simeq$ 42 K and transforms into a canted A-type antiferromagnet (cAFM) below $T_{\rm c}\simeq 20 $K. In addition, a ferroelectric polarization ${\bf P}||a$ is observed below $T_{\rm FE} $ for finite magnetic fields applied along the $b$ direction. In zero magnetic field we find a strongly anisotropic thermal expansion with certain, rather broad anomalous features. In finite magnetic fields, however, very strong anomalies arise at $T_{\rm c}$ for fields applied along each of the orthorhombic axes and at $T_{\rm FE}$ for fields along the b axis. Both phase transitions are of first-order type and strongly hysteretic. We observe a down-bending of the ICAFM-to-cAFM phase boundary $T_{\rm c}(H)$ for low magnetic fields and our data give evidence for coexisting phases in the low-field low-temperature range.

description: Dynamic voltage-current characteristics of an HTS Ag/BiSCCO composite tape are studied both experimentally and theoretically. The tape is subjected by pulsed currents with different shapes and magnitude and voltage traces are measured using the four-point method with different location of potential taps on the sample surface. Clockwise and anticlockwise hysteresis loops are obtained for the same sample depending on location of the potential taps. The dynamic characteristics deviate substantially from the DC characteristic, especially in the range of low voltages where a criterion for the critical current value is usually chosen (1-10 mkV/cm). The critical current determined from dynamic characteristics and its change with the pulse magnitude depend on location of the potential taps and on the curve branch chosen for the critical current determination (ascending or descending). The theoretical analysis is based on a model of the magnetic flux diffusion into a composite tape for a superconductor described by the flux creep characteristic. Numerical simulation based on this model gives the results in good agreement with the experimental ones and explains the observed peculiarities of the dynamic characteristics of HTS composite tapes. The difference between the magnetic diffusion into a tape and a slab is discussed.

description: Artificial immune system can be used to generate schedules in changing environments and it has been proven to be more robust than schedules developed using a genetic algorithm. Good schedules can be produced especially when the number of the antigens is increased. However, an increase in the range of the antigens had somehow affected the fitness of the immune system. In this research, we are trying to improve the result of the system by rescheduling the same problem using the same method while at the same time maintaining the robustness of the schedules.

Decolonising the Mind of the Antipodean Author: Gothic Tropes and Postcolonial Discourse in Peter Carey’s My Life as a Fake
Creators: name: Tosi, Valerie

Year: 2021

description:

This article analyses Peter Carey’s novel My Life as a Fake (2003) through the lens of genre fiction, focusing on how the Gothic mode combines with key concepts in postcolonial studies. Intertextual references to Mary Shelley’s Frankenstein, or The Modern Prometheus (1818) and analogies with Stephen King’s The Dark Half (1990) and “The Importance of Being Bachman” (1996) are investigated to contextualise Carey’s postcolonial Gothic. Furthermore, taking a cue from Frantz Fanon and Oswaldo de Andrade’s theoretical studies, I argue that the main characters of this novel display attitudes that allegorically reflect the stages through which the national literature of a former settler colony is shaped.

description: The production performance of wheatbelt farms in Western Australia is analysed to determine whether potential to exploit scale economies and improve technical efficiency has driven the trend towards increased farm size. An input-orientated stochastic frontier model is used to estimate technical efficiency and scale economies using an unbalanced panel dataset provided by BankWest for the period 1995/1996 to 2005/2006. Differences in the relative efficiency of farms are explored by the simultaneous estimation of a model of inefficiency effects. The results show the majority of wheatbelt farms operate at high levels of technical efficiency and experience increasing returns to scale. Over the study period farms became bigger to benefit from economies of scale, however average farm technical efficiency declined. More specialised farms on average are more technically efficient and have less potential to exploit scale economies. Technical efficiency and scale economies are significantly affected by farm location. The farmer/farm family characteristics do not significantly affect technical efficiency although attending an agricultural college and having a child with a strong interest to return to the farm has a positive effect on scale economies.

description: Charge noise remains the primary obstacle to the development of quantum information technologies with semiconductor spin qubits. We use an exact analytical calculation to determine the effects of quasistatic charge noise on a ring of three equally spaced exchange-coupled quantum dots. We calculate the disorder-averaged return probability from a specific initial state, and use it to determine the coherence time T2* and show that it depends only on the disorder strength and not the mean interaction strength. We also use a perturbative approach to investigate other arrangements of three or four qubits, finding that the return probability contains multiple oscillation frequencies. These oscillations decay in a Gaussian manner, determined by differences in energy levels of the Hamiltonian. We give quantitative values for gate times resulting in several target fidelities. We find that the decoherence time decreases with increasing number of qubits. Our work provides useful analytical insight into the charge noise dynamics of coupled spin qubits.

description: This paper examines what, precisely, is meant by a 'farm', the criteria for the inclusion of individual farms in a statistical register and the resulting enumerations and average sizes of farms in published statistics. Alternative measures of farm size are examined and a relatively novel measure of average farm size proposed to cope with the possibly uncertain population of farms. This is illustrated with reference to data relating to the AARES countries and to the UK. Finally the meaning of the expression 'part-time' as applied to farmers or farms is examined, with a call for great clarity in its use.

description: Enormous amounts of data are being produced everyday by sub-meters and smart sensors installed in residential buildings. If leveraged properly, that data could assist end-users, energy producers and utility companies in detecting anomalous power consumption and understanding the causes of each anomaly. Therefore, anomaly detection could stop a minor problem becoming overwhelming. Moreover, it will aid in better decision-making to reduce wasted energy and promote sustainable and energy efficient behavior. In this regard, this paper is an in-depth review of existing anomaly detection frameworks for building energy consumption based on artificial intelligence. Specifically, an extensive survey is presented, in which a comprehensive taxonomy is introduced to classify existing algorithms based on different modules and parameters adopted, such as machine learning algorithms, feature extraction approaches, anomaly detection levels, computing platforms and application scenarios. To the best of the authors' knowledge, this is the first review article that discusses anomaly detection in building energy consumption. Moving forward, important findings along with domain-specific problems, difficulties and challenges that remain unresolved are thoroughly discussed, including the absence of: (i) precise definitions of anomalous power consumption, (ii) annotated datasets, (iii) unified metrics to assess the performance of existing solutions, (iv) platforms for reproducibility and (v) privacy-preservation. Following, insights about current research trends are discussed to widen the applications and effectiveness of the anomaly detection technology before deriving future directions attracting significant attention. This article serves as a comprehensive reference to understand the current technological progress in anomaly detection of energy consumption based on artificial intelligence.

description: The Helfrich-Canham bending energy is identified with a non-linear sigma model for a unit vector. The identification, however, is dependent on one additional constraint: that the unit vector be constrained to lie orthogonal to the surface. The presence of this constraint adds a source to the divergence of the stress tensor for this vector so that it is not conserved. The stress tensor which is conserved is identified and its conservation shown to reproduce the correct shape equation.

Interpersonal dimensions of trait perfectionism, coping, and quality of intimate relationships
Creators: name: Haring, Michelle Louise
Publisher: name: University of British Columbia

description: Perfectionism is a multidimensional trait, including both intra- and interpersonal dimensions. While many studies have linked perfectionism to a variety of intrapersonal problems, to date little work has addressed the interpersonal consequences of trait perfectionism. The present study examined the relationship between perfectionism, marital coping and marital functioning in a sample of 76 married or common-law couples. First, this study examined whether perfectionism was related to several indices of marital adjustment both for the self and for the partner. Second, the relationship between perfectionism and the types of coping strategies used in response to marital problems was explored. Next, the ability of perfectionism to predict marital coping and adjustment independent of its associations with depression and neuroticism was assessed. Finally, this study sought to clarify the how perfectionism is related to marital adjustment. With respect to this last question, two models of the relationship between perfectionism, coping and marital adjustment were tested. Based on Hewitt and Flett's (in press) conceptualization of the relationship between perfectionism and maladjustment, a model was tested in which negative coping efforts mediate the relationship between perfectionism and self and partner's marital adjustment. The second model tested was a moderational model in which perfectionism interacts with coping to produce marital difficulties. The results of this study suggest that one of the interpersonal dimensions of perfectionism, spouse-prescribed perfectionism, is strongly negatively associated with marital adjustment for both the self and the partner. This dimension also predicts the types of coping strategies used in response to marital difficulties. In addition, it was found that perfectionism predicted variance in marital functioning and marital coping above and beyond the effects of depression and neuroticism. While no evidence for a moderational model was found, the present study provided support for Hewitt and Flett's (in press) theoretical model. That is, the use of negative coping strategies mediated the relationship between spouse-prescribed perfectionism and poorer marital functioning for both the self and the partner. Overall, this study highlights the importance of perfectionism in the interpersonal domain.

description: Gamma-ray bursts (GRB), at least those with a duration longer than a few seconds are the most energetic events in the Universe and occur at cosmological distances. The ECLAIRs micro-satellite, to be launched in 2009, will provide multi-wavelength observations of GRB, to study their astrophysics and to use them as cosmological probes. Furthermore in 2009 ECLAIRs is expected to be the only space borne instrument capable of providing a GRB trigger in near real-time with sufficient localization accuracy for GRB follow-up observations with the powerful ground based spectroscopic telescopes available by then. A "Phase A study" of the ECLAIRs project has recently been launched by the French Space Agency CNES, aiming at a detailed mission design and selection for flight in 2006. The ECLAIRs mission is based on a CNES micro-satellite of the "Myriade" family and dedicated ground-based optical telescopes. The satellite payload combines a 2 sr field-of-view coded aperture mask gamma-camera using 6400 CdTe pixels for GRB detection and localization with 10 arcmin precision in the 4 to 50 keV energy band, together with a soft X-ray camera for onboard position refinement to 1 arcmin. The ground-based optical robotic telescopes will detect the GRB prompt/early afterglow emission and localize the event to arcsec accuracy, for spectroscopic follow-up observations.
