description: We built randomly cross-linked model PDMS networks and used Molecular Dynamics Methods to obtain stress-strain curves. Mooney-Rivlin (MR) analysis was used to estimate the shear moduli. We applied Primitive Path analysis (PPA) and its variation, Phantom Primitive Path analysis (3PA), to estimate the entanglement and the cross-link moduli, respectively. The MR moduli estimates are in good agreement with the sum of the entanglement and the cross-link moduli, and we observe that the stress-strain data collapse to a universal form when reduced with the PPA and 3PA moduli. We studied how the MR parameters $\mathrm{C}_1$, $\mathrm{C}_2$ vary from cross-link to entanglement dominated networks. For the latter, we observed a $40\%$, $60\%$ contribution of $2\,\mathrm{C}_1$, $2\,\mathrm{C}_2$ to the shear modulus, respectively. Finally, we fitted several models to the data. While all fits are good, the estimates for the entanglement and the cross-link moduli vary significantly when compared to our PPA and 3PA benchmarks.

description: We review three algorithms that scale the infinity-norm of each row and column in a matrix to 1. The first algorithm applies to unsymmetric matrices, and uses techniques from graph theory to scale the matrix. The second algorithm applies to symmetric matrices, and is notable for being asymptotically optimal in terms of operation counts. The third is an iterative algorithm that works for both symmetric and unsymmetric matrices. Experimental evidence of the effectiveness of all three algorithms in improving the conditioning of the matrix is demonstrated.

description: The aim of this thesis is to explore the psychology and reactions of investors as well as investigate the external factors that affect their behavior during the first months of the COVID-19 pandemic in terms of Behavioral Finance. Investors’ behavior and psychology are considered as structural elements of the field of Behavioral Finance and they are also known as key factors that influence the financial markets, especially in times of crisis when markets are characterized by extreme volatility. Hence, the aim of this thesis is to link the field and its characteristics with the current market situation which since the outbreak of the COVID-19 pandemic is been characterized by extreme volatility. The empirical approach of this thesis focuses on the psychology and behavior of Greek investors from the beginning of the pandemic until today. The survey is conducted through an anonymous questionnaire which is distributed to 225 private investors. The conclusions drawn from this research are another presumption of the importance of investors’ psychology in the field of financial markets. These conclusions can also be very beneficial to all market participants as they contribute to the development of investors’ profile concerning the current situation.
Computational Geometry in High-Dimensional Spaces

description: In this project, we provide a review of efficient solutions to a few high-dimensional CG problems, with particular focus on the problem of nearest neighbour search. For the problems we examine, the general approach will be to either reduce the dimension (using the JL transform) or to preprocess the data and group together points that are close together (using locality sensitive hashing). Finally, we apply these techniques to a relaxed version of the unit disc cover problem, an NP-Hard facility location problem that has only been effectively approximated in the low-dimensional case.
Pseudorapidity Distributions of Charged Particles in d + Au and p + p Collisions at $\sqrt{s_{_{NN}}}$ = 200GeV

description: The measured pseudorapidity distributions of primary charged particles are presented for d + Au and p + p collisions at ${\sqrt{s_{_{NN}}} =}$ 200 GeV over a wide pseudorapidity range of ${\rm \mid η\mid \le}$ 5.4. The results for d + Au collisions are presented for minimum-bias events and as a function of collision centrality. The measurements for p + p collisions are shown for minimum-bias events. The ratio of the charged particle multiplicity in d + Au and p + A collisions relative to that for inelastic p + p collisions is found to depend only on ${< N_{part} >}$, and it is remarkably independent of collision energy and system mass. The deuteron and gold fragmentation regions in d + Au collisions are in good agreement with proton nucleus data at lower energies.

The Art of Deleting: On Poetry and Erasure (Q&A)

description: This document registers the Q&A of the UCLA Information Studies Colloquium "The Art of Deleting: On Poetry and Erasure" by Álvaro Seiça. The talk presents recent outcomes connected to the research and book project “The Art of Deleting” (ARTDEL). ARTDEL is a 3-year project (2018-21) funded by the European Commission’s Marie Skłodowska-Curie Global Fellowship and the Research Council of Norway, at the University of Bergen, the University of California, Los Angeles, and the University of Coimbra. The use of material and graphic erasure in the composition and formal display of poems has a varied tradition during the 20th century and, most prominently, in the early 21st century. Marks of erasure in literary works can be traced back at least to Heinrich Heine’s poetical narrative Reisebilder (1827), in which the author denounces and parodies state censorship by mimicking the censors’ cuts. Yet, since then, are all writers, artists, and poets using erasure in the same way? An overview of this expanding visual and literary form suggests that there are often formalist or conceptual concerns with no political aims, but that a great number of poets and artists also highlight themes and practices of resistance and activism, by connecting erasure with censorship and surveillance. While the first part of the talk will contrast clusters of erasure poetics, the second part will present archival research related to how book censorship and erasure unfolded under the New State, the Portuguese corporatist and fascist regime of 1933-74. By searching the archives of the political police PIDE/DGS and the Censorship Commission, by inventorying, for the first time ever, the full card index of the Censorship Commission, and by unearthing part of the original books censored by the regime, it is now possible to better understand practices, motives, and objectives of material erasure that served the propaganda of Salazar and Caetano’s regime. Having the knowledge of legal and political documents, it is appropriate to ask whether contemporary poets are using erasure or not in relation to history via documentary forms. While that does not seem to be the case in Portugal, in the United States there has been an erasing impulse, especially after the 2000s, to use declassified documents and redaction as found material for new creative work. The talk concludes with reflections on how different ideologic regimes in the post-Second World War in the US, Portugal and China seek to identify common threats among writers on the grounds of national security, patriotism, political subversion, pornography, gender roles or morals.

description: This Special Issue of the Astrophysical Journal Letters is dedicated to presenting initial results from the Great Observatories Origins Deep Survey (GOODS) that are primarily, but not exclusively, based on multi--band imaging data obtained with the {\it Hubble Space Telescope} ({\it HST}) and the Advanced Camera for Surveys (ACS). The survey covers roughly 320 square arcminutes in the ACS F435W, F606W, F814W, and F850LP bands, divided into two well-studied fields. Existing deep observations from the {\it Chandra} X-ray Observatory (\cxo) and ground-based facilities are supplemented with new, deep imaging in the optical and near-infrared from the European Southern Observatory (ESO) and from the Kitt Peak National Observatory (KPNO). Deep observations with the {\it Space Infrared Telescope Facility} (SIRTF) are scheduled. Reduced data from all facilities are being released worldwide within three to six months of acquisition. Together, this data set provides two deep reference fields for studies of distant normal and active galaxies, supernovae, and faint stars in our own galaxy. This paper serves to outline the survey strategy and describe the specific data that have been used in the accompanying letters, summarizing the reduction procedures and sensitivity limits.

Σκοπός της παρούσας διπλωματικής εργασίας είναι η διερεύνηση, τόσο θεωρητικά όσο και εμπειρικά των παραγόντων που επηρεάζουν τη ζήτηση ηλεκτρικής ενέργειας.

Λόγω κυρίως του μεγάλου όγκου δεδομένων που χρησιμοποιούμε, η ανάλυση διεξάγεται μέσω της ανάλυσης σε κύριες συνιστώσες. Μέσω αυτής εκτιμώνται οι παράγοντες που επηρεάζουν τη ζήτηση ενέργειας καθώς και οι επιβαρύνσεις κάθε παράγοντα. Στη συνέχεια βάση τα χαρακτηριστικά που παρουσιάζει η κάθε κοινή συνιστώσα, προσδίδουμε ερμηνεία και την αντιστοιχίζουμε στον παράγοντα που αντιπροσωπεύει.
description: In the electricity market there must be a balance between supply and demand due to the economically unprofitable storage of electricity. Both production and demand are characterized by seasonality and periodicity and they are also influenced by unbalanced factors such as weather conditions. The purpose of this essay is to investigate, both theoretically and empirically, the factors that affect the demand of electricity. The object of study are the fluctuations presented by the electricity demand in Greece, the investigation of the common risk factors at national level but also in selected countries. The analysis in first focuses on Greece and it extends to a set of countries that have common weather conditions. Due to the large amount of data, factor analysis is the most appropriate method. It indicates the factors that affect energy demand.

We have subsequently performed a thorough study of the different states of bulk Iron. We determine the minimal basis set required to obtain reliable orderings of ground and excited states. We find that the most stable fcc phase is a spiral with an equilibrium lattice constant 3.56 A.

description: The Majoron, the Nambu-Goldstone boson of lepton number symmetry, is an interesting candidate for dark matter as it deeply connects the dark matter and neutrino physics. In this paper, we consider the Majoron dark matter as pseudo Nambu-Goldstone boson with TeV-scale mass. The heavy Majoron generally has the large decay constant and tiny Yukawa couplings to light right-handed neutrinos which are required by cosmological and astrophysical observations. That makes it difficult to realize the desired amount of the relic abundance of Majoron dark matter. We consider three improved scenarios for the generation of Majoron, dubbed as Majorogenesis, in the early universe and find in all cases the parameter space compatible with the relic abundance and cosmic-ray constraints.

description: This paper proposes a new volume function for calculation of the entropy of planar granular assemblies. This function is extracted from the antisymmetric part of a new geometric tensor and is rigorously additive when summed over grains. It leads to the identification of a conveniently small phase space. The utility of the volume function is demonstrated on several case studies, for which we calculate explicitly the mean volume and the volume fluctuations.

description: During the Great Recession, work requirements for various safety net programs were relaxed, and it has been argued that these contributed to high unemployment rates and long unemployment durations. One work requirement in the SNAP program applies to "able-bodied adults without dependents," and is lifted when participants reach age 50. Using a regression discontinuity approach that removes bias from age rounding, this article finds no evidence the requirement affects the probability of compliant employment when the requirement is in place.

description: Recently quantum simulators have been constructed to investigate experimentally the most prominent theoretical four-point many-body system described by the Hubbard model. By varying the coupling strength of the four-point interaction in relation to the kinetic term, one can analyze the phase structure of the model. This intriguing fact leads us to investigate whether similar Hamiltonians with four-point interactions can also be studied as a function of their four-point coupling strength. In this paper, we reexamine the Nambu-Jona-Lasinio model, regarding it generally beyond the context of quantum chromodynamics. Essentially, it is a model in which particle-antiparticle pairing leads to a BCS-like condensate, with the result that chiral symmetry is broken dynamically in the strong-coupling regime. To study the behavior of the system, it is necessary to move from this regime to a hypothetical regime of weak coupling, altering the coupling strength of the interaction arbitrarily. In order to do this, the gap equation must be regarded as complex and its Riemann surface structure must be known. We do this and obtain a continuous quantum phase transition characterized by the development of a complex order parameter (the dynamically generated mass) from the second sheet of the Riemann surface, as we move into the weak-coupling regime. The power-law behavior of the order parameter in the vicinity of the phase transition point is demonstrated to be independent of the choice of the regularization scheme with the critical exponent as $β\approx 0.55$. At the same time, the isovector pseudoscalar modes retain their feature as Goldstone modes and still have zero mass, while the isoscalar scalar meson follows the behavior of the order parameter and gains a width. Energetically, this mode is not favored over the normal, uncondensed mode but would have to be accessed through an excitation process.

description: Comparative debugging makes use of direct comparisons between two different runs of the same or similar programs to diagnose unexpected and often erroneous behaviour in the application or applications. Comparative debugging is an important technique for STFC and for computational scientists at other labs around the world. As a six month project at STFC, in collaboration with Rogue Wave Software Inc., an automated comparative debugging script (CDTV) has been created that makes use of the command interface of RogueWave’s TotalView debugger. To demonstrate this script, example scenarios are shown and discussed within the report, highlighting the key features, current limitations and possible improvements that could guide any future work. The CDTV script has been shown to be capable of locating differences caused by an artificial bug introduces into a serial program written in C or in Fortran as well as parallel programs using MPI and OpenMP. As well as simple test codes, the script has been demonstrated using a real application, the UK Turbulence Consortium’s Shock/Boundary Layer Interaction code. We believe that similar large scale applications could benefit from comparative debugging without making major changes to the underlying CDTV script.

description: Electromagnetic properties of periodic two-dimensional sub-wavelength structures consisting of closely-packed inclusions of materials with negative dielectric permittivity $ε$ in a dielectric host with positive $ε_h$ can be engineered using the concept of multiple electrostatic resonances. Fully electromagnetic solutions of Maxwell's equations reveal multiple wave propagation bands, with the wavelengths much longer than the nanostructure period. It is shown that some of these bands are described using the quasi-static theory of the effective dielectric permittivity $ε_{qs}$, and are independent of the nanostructure period. Those bands exhibit multiple cutoffs and resonances which are found to be related to each other through a duality condition. An additional propagation band characterized by a negative magnetic permeability develops when a magnetic moment is induced in a given nano-particle by its neighbors. Imaging with sub-wavelength resolution in that band is demonstrated.

description: We study the gravitational field of ultrarelativistic spinning objects (gyratons) in a modified gravity theory with higher derivatives. In particular, we focus on a special class of such theories with an infinite number of derivatives known as "ghost-free gravity" that include a non-local form factor such as $\exp(-\Box\ell^2)$, where $\ell$ is the scale of non-locality. First, we obtain solutions of the linearized ghost-free equations for stationary spinning objects. To obtain gyraton solutions we boost these metrics and take their Penrose limit. This approach allows us to perform calculations for any number of spacetime dimensions. All solutions are regular at the gyraton axis. In four dimensions, when the scale non-locality $\ell$ tends to zero, the obtained gyraton solutions correctly reproduce the Aichelburg--Sexl metric and its generalization to spinning sources found earlier by Bonnor. We also study the properties of the obtained four-dimensional and higher-dimensional ghost-free gyraton metrics and briefly discuss their possible applications.

A Phenomenological Analysis of Black African Women’s Experiences of Engagement in Counselling in the UK
Creators: name: Shundi, Lillian
Publisher: name: University of East London
Year: 2020

description: This study explores Black African women’s experiences of engaging in counselling in the UK, which was achieved by exploring participants’ lived counselling experiences. The study also explored whether the participants’ experiences will impact future engagement with counselling. This study used Interpretative Phenomenological Analysis (IPA) as the methodology. The six participants recruited for this study had all migrated to the UK from Africa. The findings from this study describe participants’ experiences of engaging in counselling, as interpreted within the three emerging master themes, namely; Preconceptions, stigma, skepticism about attending counselling and preferred ways of coping, The important characteristics within the counselling experience and Post counselling reflections on the therapeutic process and changed perceptions. The first master theme groups together the participants’ cultural beliefs about counselling before they began. This included preconceptions, scepticism about the therapist, stigma associated with counselling engagement, and the participants’ preferred ways of coping with psychological distress as an alternative for counselling. The second master theme describes the participants’ experiences of being in counselling and present with a therapist. This was influenced by the therapist’s characteristics, the therapist’s way of working, and the quality of therapeutic relationship established. The third master theme encapsulates the participants’ post therapy reflections, where they described the end of their counselling journey. This included their comments about aspects of the counselling that they felt needed changing to make counselling a more positive experience for them, should they require it in the future, including the counselling pathway and the counselling environment. All six participants expressed a change of perception about various aspects of counselling after they had completed their counselling journey. Overall, this was found to be a good experience despite two participants being dissatisfied with their counselling. The findings from this study highlight that different factors influence this group of Black African women’s engagement with counselling. These include personal, structural, and institutional factors. The study offers suggestions for policy makers, health care providers, and the practice of counselling, to consider providing services more tailored to meet the needs of Black African women in the UK.

Η νομική προσέγγιση του επίμαχου αδικήματος (άρ. 31 ν. 4443/2016) προϋποθέτει την κατανόηση λειτουργίας του Χρηματιστηρίου σε πρακτικό επίπεδο. Έτσι, σημαντικό τμήμα της εργασίας αφιερώνεται στην ανάλυση κάποιων κεντρικών πρακτικών ζητημάτων της λειτουργίας του Χρηματιστηρίου, προκειμένου στη συνέχεια να καταστεί ευκολότερη η οριοθέτηση του αξιοποίνου συγκεκριμένων συμπεριφορών. Η εργασία ξεκινά με μία ιστορική αναδρομή στην εθνική και ευρωπαϊκή έννομη τάξη αναφορικά με τα αδίκημα της χειραγώγησης της αγοράς. Στη συνέχεια, καταπιάνεται με γενικά ζητήματα σε σχέση με το ισχύον εθνικό και ενωσιακό πλαίσιο, όπως το προστατευόμενο έννομο αγαθό και την παράσταση προς υποστήριξη της κατηγορίας. Στο τρίτο και εκτενέστερο μέρος της εργασίας αναλύονται οι επιμέρους βασικές μορφές τέλεσης του αδικήματος της χειραγώγησης της αγοράς, ενώ παράλληλα δίνονται και παραδείγματα πρακτικών για έκαστη μορφή. Στο τέταρτο μέρος της εργασίας αναλύεται η συρροή των επιμέρους μορφών και η σχέση του άρ. 31 ν. 4443/2016 με το αδίκημα της απάτης του κοινού ποινικού κώδικα (άρ. 386 νΠΚ). Η εργασία κλείνει με μια σύντομη ανακεφαλαίωση των θέσεων της εργασίας για τα σημαντικότερα ζητήματα της χειραγώγησης της αγοράς.
description: The paper analyzes the main interpretative issues in relation to the offense of market manipulation, as formulated by Law 4443/2016. The legal approach of the offense in question (art. 31 Law 4443/2016) presupposes the understanding of the operation of the Stock Exchange on a practical level. Thus, a significant part of the work is devoted to the analysis of some central practical issues of the operation of the Stock Exchange, in order to then make it easier to delimit the crime of specific behaviours. The work begins with a historical review of the national and European legal order regarding the offenses of market manipulation. It then addresses general issues related to the current national and EU framework, such as the legally protected right and representation in support of the accusation. In the third and more extensive part of the work, the individual basic forms of committing the crime of market manipulation are analyzed, while at the same time examples of practices are given for each form. In the fourth part of the work is analyzed the confluence of the individual forms and the relation of no. 31 Law 4443/2016 with the offense of fraud of the common criminal code (no. 386 of the Criminal Code). The paper concludes with a brief summary of job postings on the most important issues of market manipulation.

description: We have observed a dissipative phase diffusion branch in arrays of hysteretic high-Tc intrinsic Josephson junctions. By comparing the data with a thermal activation model we extract the impedance seen by the junction in which phase diffusion is occurring. At the plasma frequency this junction is isolated from its environment and it sees its own large (~ kilo Ohm) impedance. Our results suggest that stacks of Josephson junctions may be used for isolation purposes in the development of a solid state quantum computer.

description: This study seeks to understand how therapists experience their work with clients who selfrefer as living in poverty. Poverty is very rarely highlighted within counselling psychology publications and very little empirical research exists relating to how therapists understand this phenomenon. The under researched nature of poverty is surprising given this issue is becoming a topic of current debates alongside a rise in the number of individuals living in poverty and self-referring for therapy. The present study highlights a range of difficulties that therapists may face whilst working with clients living in poverty, how these difficulties may affect the work and how such difficulties are managed. The aim of these findings is to increase current knowledge about what is possible within the world of therapy and to raise awareness from which practitioners, students, training institutions and policy makers could become more informed. Eight psychotherapists took part in semi-structured interviews and Interpretative Phenomenological Analysis (IPA) was used in analysing the data. The results elicited three superordinate themes: the first, “Resilience in the struggle to engage with therapeutic work”, the second theme involved “Struggling to promote social activism” and thirdly, “Navigating multiple challenges and barriers’. The findings are examined in light of how they illuminate and diverge from various aspects of poverty-related literature and research. Suggestions are made for training, supervision, and practice, and for future research relating to poverty and mental health.

description: The Hawking radiation of Weyl neutrinos in an arbitrarily accelerating Kinnersley black hole is investigated by using a method of the generalized tortoise coordinate transformation. Both the location and temperature of the event horizon depend on the time and on the angles. They coincide with previous results, but the thermal radiation spectrum of massless spinor particles displays a kind of spin-acceleration coupling effect.

description: Background: With evidence of rising mental health needs in children and young people and cuts in specialist provision, the role of schools in the prevention of child mental health issues has become increasingly pertinent. Primary school teachers work with an age group for whom early intervention is of particular relevance and are being asked to perform a range of educational and preventative tasks relevant to the mental health of their pupils. Objectives: This study aimed to explore primary school teachers' perspectives on their role in the prevention of child mental health issues and gain a better understanding of opportunities and barriers they may encounter in this role. Design: This was an exploratory study using thematic analysis. A critical realist position was taken which allowed both the content of the data and the context of the teacher’s views and experiences to be considered. Method: Semi-structured interviews were carried out with 11 teachers working across 10 primary schools. Data was analysed using thematic analysis, following the stages of analysis outlined by Braun and Clarke (2013). Results: Two overarching themes were identified: i) Understandings of child mental health and ii) School’s place in society; teacher roles and responsibilities. Conclusions: The findings demonstrate the complex position primary school teachers hold, in which they face dilemmas around the boundaries of their role and contend with the restrictions and demands of the current UK education system. The findings indicate a lack of confidence in how best to identify and respond to children presenting with mental health issues and a desire for further training on the subject of mental health. The findings highlighted a need for greater clarity in the parameters of a primary school teacher's role and further consideration of the feasibility of incorporating mental health education and prevention into an already high workload.
Can Participation in a Shared Reading Activity Produce Relational Benefits Between Foster Carers and the Children in Their Care?

description: As a population, children in care (CiC) are found to be at an increased risk of a range of negative outcomes associated with poor educational attainment and difficult early attachment relationships. Having access to educational interventions in key areas such as literacy and the opportunity to develop positive, stable and caring relationships is seen as crucial to overcoming many of these disadvantages. Professionals supporting CiC, including those within the area of special educational needs and disability (SENDs), are duty bound to work together towards this aim. Paired reading is an educational intervention that has been used within the researcher’s local authority (LA) for several years and is credited with helping children, including foster children, achieve significant improvements in their reading. In addition, feedback from participants and some research (Forsman, 2017; Osborne, Alfano & Winn, 2010) into the efficacy of this intervention has suggested that participation might also benefit the foster carer/child relationship. In this qualitative study, semi-structured interviews were used to obtain and explore foster carers and children’s views of a shared reading (SR) intervention with respect to its impact on their relationship. Additional techniques were also adapted and used to support the children to express their views. Thematic analysis identified five key themes supportive of previous findings which suggest SR interventions can enhance the relationship between foster carers and foster children. Results also suggest, however, that more needs to be done to emphasise the relational benefits to potential participants. This research makes an important contribution to the understanding of SR practices and informs the promotion, recommendation and delivery of future interventions and the work of Educational Psychologists (EPs) and other professionals supporting this particularly vulnerable group of children.

A short note on floor vibration management and control
Creators: name: Taale, Alireza

description: Modern large span floors and light weight structural systems tend to vibrate under service loads. As a matter of fact, the effect of floor vibration might have negative impacts on daily routines of a structure ranging from a single family household to a rotating machinery in a chemical plant and even a multi-billion dollar hydro power plant. Anywhere alongside this broad spectrum, human comfort, performance of equipment and or structural serviceability may be compromised. Investigating floor vibration has a unique set of properties for which it becomes a suitable topic to apply theory of structural dynamics. This particular system could potentially be simplified enough to fit within a classic dynamics problem. A quick glance at available publications on this topic indicates that numerous approaches are convention in various parts of the world. This provides us the opportunity to familiarize with a few and match them with the topics discussed within the context of CIVL507 course. A literature review is first conducted regarding the vibration problems associated with the floors, and various techniques to minimize the impact of the vibration (e.g. rehabilitation or design state procedures) A background information will be prepared on various levels of human perception of vibration in terms of acceleration. A couple of methods will then be identified and handpicked to characterize the problem based on Single Degree of Freedom approach. Two case studies will also be provided in which the abovementioned methods are implemented (at least one method per case). The first case will be a conventional solution at the design level which result in a desired effective mass stiffness and or damping mechanism in order to remain within the desired comfort levels. The second case will simulate the response of a TMD compensated floor system in response to a harmonic excitation .

description: The goals of the 1902 Reclamation Act have always been the development of irrigated agriculture and enhancement of the "family farm." Although administrative procedures and institutional arrangements have changed over the years, these goals have remained in explicit or implicit form. However, there has been little discussion of the cost of irrigation and rural development policies or of how efficient and equitable they are in their present state. Recent proposals of the Department of the Interior would more strictly enforce the 75 year old 160 acre restriction for recipients of federally subsidized water in order to make farming in Reclamation projects still economically viable while at the sam~ time promoting smaller units of production than now exist. Large farm operators and excess landowners oppose these new regulations as inequitable and destructive of efficient agriculture. Their view is that changing enforcement of the law at this time would be unfair. Land reform groups insist that administrative procedures be reformed to force a strict conformity with acreage and residency provisions and that the subsidy be used to support the development of modest-sized, family farms. The debate over future Reclamation policy revolves around the issues of farm size efficiency and equitable distribution of the water subsidy. Interestingly most of the published research has concentrated on the questions of efficiency and viability (Hall and LeVeen; USDA; Goldman et al.). This paper examines the water subsidy in Reclamation irrigation projects, its magnitude and distribution under current administration of the law, and under proposed changes.

description: We investigate the origin of asymmetry in various measured current-voltage (I-V) characteristics of molecules with no inherent spatial asymmetry, with particular focus on a recent break junction measurement. We argue that such asymmetry arises due to unequal coupling with the contacts and a consequent difference in charging effects, which can only be captured in a self-consistent model for molecular conduction. The direction of the asymmetry depends on the sign of the majority carriers in the molecule. For conduction through highest occupied molecular orbitals (i.e. HOMO or p-type conduction), the current is smaller for positive voltage on the stronger contact, while for conduction through lowest unoccupied molecular orbitals (i.e. LUMO or n-type conduction), the sense of the asymmetry is reversed. Within an extended Huckel description of the molecular chemistry and the contact microstructure (with two adjustable parameters, the position of the Fermi energy and the sulphur-gold bond length), an appropriate description of Poisson's equation, and a self-consistently coupled non-equilibrium Green's function (NEGF) description of transport, we achieve good agreement between theoretical and experimental I-V characteristics, both in shape as well as overall magnitude.
