description: [PPP contracts: what are the potential for commitment and the difficulties of application? - Case of the MENA region -]
Résumé:
Un Partenariat Public Privé (PPP) est un contrat légal entre une entité publique et une ou plusieurs entités privées dans le but est de développer des projets ou d’administrer des services publics. Dans ce contexte, notre contribution vienne; par l’utilisation d’une approche d’analyse et de comparaison et sur la base des statistiques, bases des donnés, et plateformes des organisations internationales ; pour objectif de montrer les différentes expériences entre les pays de la région MENA en termes des capacités d’établissement des projets PPP, et d’identification des obstacles et barrières qui empêchent ces projets à réaliser complètement.
Cette étude d’analyse a conclu que la plupart des pays de la région MENA sont beaucoup souffert dans un processus plus long pour l’établissement et la gestion des projets PPP, et celui en raison de : manque d’expériences et d’expertise dans la négociation et le management des contrats avec les privés, manque des sources de financement des grands projets, manque d’un cadre juridique et réglementaire -dans la plupart des pays comparés- afin d’encadrer et adapter ce type de contrat.

Abstract:
A public private partnership (PPP) is a legal contract between a public entity and one or more private entities for the purpose of developing projects or administering public services. In this context, our contribution comes; through the use of an analysis and comparison approach and based on statistics, databases and platforms of international organizations; aims to show the different experiences between MENA countries in terms of the capacity to establish PPP projects and to identify barriers in that were prevent these projects from fully realizing.
This analysis concluded that most countries in the MENA region are suffering greatly in a longer process for the establishment and management of PPP projects, and that due to: lack of experience and expertise in negotiating and management of contracts with private sector, lack of funding sources for major projects, lack of a legal and regulatory framework-in most countries compared-in order to frame and adapt this type of contract.

description: Jet production in relativistic heavy ion collisions is studied using Pb+Pb collisions at a center of mass energy of 2.76 TeV per nucleon. The measurements reported here utilize data collected with the ATLAS detector at the LHC from the 2010 Pb ion run corresponding to a total integrated luminosity of 7 Âµ b^(-1). The results are obtained using fully reconstructed jets using the anti-k t algorithm with a per-event background subtraction procedure. A centrality-dependent modification of the dijet asymmetry distribution is observed, which indicates a higher rate of asymmetric dijet pairs in central collisions relative to periphal and pp collisions. Simultaneously the dijet angular correlations show almost no centrality dependence. These results provide the first direct observation of jet quenching. Measurements of the single inclusive jet spectrum, measured with jet radius parameters R=0.2, 0.3, 0.4 and 0.5, are also presented. The spectra are unfolded to correct for the finite energy resolution introduced by both detector effects and underlying event fluctuations. Single jet production, through the central-to-peripheral ratio R CP, is found to be suppressed in central collisions by approximately a factor of two, nearly independent of the jet p T. The R CP is found to have a small but significant increase with increasing R, which may relate directly to aspects of radiative energy loss.

description: This paper considers the problem of characterizing the simplest discrete point sets that are aperiodic, using invariants based on topological dynamics. A Delone set whose patch-counting function N(T), for radius T, is finite for all T is called repetitive if there is a function M(T) such that every ball of radius M(T)+T contains a copy of each kind of patch of radius T that occurs in the set. This is equivalent to the minimality of an associated topological dynamical system with R^n-action. There is a lower bound for M(T) in terms of N(T), namely N(T) = O(M(T)^n), but no general upper bound. The complexity of a repetitive Delone set can be measured by the growth rate of its repetitivity function M(T). For example, M(T) is bounded if and only if the set is a crystal. A set is called is linearly repetitive if M(T) = O(T) and densely repetitive if M(T) = O(N(T))^{1/n}). We show that linearly repetitive sets and densely repetitive sets have strict uniform patch frequencies, i.e. the associated topological dynamical system is strictly ergodic. It follows that such sets are diffractive. In the reverse direction, we construct a repetitive Delone set in R^n which has M(T) = O(T(log T)^{2/n}(log log log T)^{4/n}), but does not have uniform patch frequencies. Aperiodic linearly repetitive sets have many claims to be the simplest class of aperiodic sets, and we propose considering them as a notion of "perfectly ordered quasicrystal".

The use of CIS in environmental planning

Publisher: name: The University of British Columbia

description: Coalmine reclamation is a major component of mine planning. Reclamation planning of a mine starts at the inventory phase, where biophysical data from pre-disturbance surveys must be collected. Much of this data can be collected from satellite imagery, digital orthophotos, topographic maps, ground data collection as well as existing digital data provided by the related Provincial and Federal Government Ministries. Once this data is collected all of the data can utilized in a Geographic Information System to map the data as well as relate the database information to the spatial data and use this as the base for recording and analyzing pre-disturbance levels, biophysical information, reclamation objectives, monitoring successes, current status of the disturbed areas and to predict future responses. The use of CIS in reclamation planning allows for quick, accurate, and precise management of data. CIS allows quicker and more convenient summaries of quantifiable data thus improving efficiency in appraising present plans to determine if they will meet with regulations and required reclamation standards (e.g. required amount of wildlife habitat to be replaced, areas, distances, etc.) The process of mining is not a single disturbance event; it encompasses an on-going disturbance of land necessitating the use of an on-going management. Updates to a CIS database can be accomplished quickly and accurately. Multiple scenario modelling can be undertaken by making small changes to the CIS model (e.g. a CIS model allows manipulation of data and what-if scenarios quicker, cheaper, and with less environmental disturbance than trials on real land). The ability to run predictive scenarios will also make it possible to plan ahead which is the most pro-active technique that can be done. Modelling can help support theories or plans for reclamation work before the work has actually started on the reclamation - i.e. an actual working model of a proposed reclamation plan will be accepted by government and public much easier than a plan that has only literature to back it up. A considerable reduction in reclamation costs may be noticed from enhanced pre-planning of reclamation and decreased uncertainty in the planning procedure.

description: We present a numerical implementation of the time-dependent surface flux (tSURFF) method [New J. Phys. 14, 013021 (2012)], an efficient computational scheme to extract photoelectron energy spectra, to the time-dependent multiconfiguration self-consistent-field (TD-MCSCF) method. Extending the original tSURFF method developed for single particle systems, we formulate the equations of motion for the spectral amplitude of orbital functions constutiting the TD-MCSCF wave function, from which the angle-resolved photoelectron energy spectrum, and more generally, photoelectron reduced density matrices (RDMs) are readiliy obtained. The tSURFF method applied to the TD-MCSCF wave function, in combination with an efficient absorbing boundary offered by the infinite-range exterior complex scaling, enables accurate {\it ab initio} computations of photoelectron energy spectra from multielectron systems subject to an intense and ultrashort laser pulse with a computational cost significantly reduced compared to that required in projecting the total wave function onto scattering states. We apply the present implementation to the photoionization of Ne exposed to an attosecond extreme-ultraviolet (XUV) pulse and above-threshold ionization of Ar irradiated by an intense mid-infrared laser field, demonstrating both accuracy and efficiency of the present method.

description: It is shown that, contrary to previous claims, a scalar tensor theory of Brans-Dicke type provides a relativistic generalization of Newtonian gravity in 2+1 dimensions. The theory is metric and test particles follow the space-time geodesics. The static isotropic solution is studied in vacuum and in regions filled with an incompressible perfect fluid. It is shown that the solutions can be consistently matched at the matter vacuum interface, and that the Newtonian behavior is recovered in the weak field regime.

description: Broad, asymmetric, and red-skewed Fe Kalpha emission lines have been observed in the spectra of low-mass X-ray binaries hosting neutron stars (NSs) as a compact object. Because more than one model is able to describe these features, the explanation of where and how the red-skewed Fe lines are produced is still a matter of discussion. It is broadly accepted that the shape of the Fe Kalpha line is strongly determined by the special and general relativistic effects occurring in the innermost part of the accretion disk. In this relativistic framework, the Fe fluorescent lines are produced in the innermost part of the accretion disk by reflection of hard X-ray photons coming from the central source (corona and/or NS surface). We developed an alternative and nonrelativistic model, called the windline model, that is capable to describe the Fe line features. In this nonrelativistic framework, the line photons are produced at the bottom of a partly ionized outflow (wind) shell as a result of illumination by the continuum photons coming from the central source, and the red-skewness of the line profile is explained by repeated electron scattering of the photons in a diverging outflow. Because GX~13+1 is a well-known disk-wind source, it is a perfect target for testing the windline model and comparing it to the relativistic one. In order to access the goodness of the fit and distinguish between the two line models, we used the run-test statistical method in addition to the canonical $χ^2$ statistical method. The diskline and windline models both fit the asymmetric GX13+1 Fe line well. From a statistical point of view, for the two observations we analyzed, the run-test was not able to distinguish between the two Fe line models, at 5% significance level.

description: Employed as midwives, wise women, or healers, female medical practitioners of various faiths disseminated medical knowledge and supplied information pertinent to religious and legal rulings in early modern Europe. While scholars have noted this role for Christian women, they have not studied the unique position of female Jewish healers with regard to municipal regulations, communal politics, medical knowledge, and legal consultations. This dissertation examines the role and influence of Jewish midwives in early modern Western Europe, addressing their interactions with communal leaders, physicians, Christian medical practitioners, and bureaucrats. Exploring their medical influences, their engagement with administrative knowledge systems, and their intellectual status in the eyes of prominent male leaders, this dissertation demonstrates that attention to the roles of Jewish midwives yields new understandings of the structures of knowledge and authority that undergirded early modern European society. Through archival and printed sources in Hebrew, Yiddish, Dutch, and German, the dissertation argues that Jewish midwives offer a crucial analytical lens for understanding many of the shifts in early modern Jewish communal life, medical culture, gender relations, and municipal bureaucracy. It tells the story of how a discrete body of knowledge crossed medical, legal, religious, and linguistic boundaries, allowing Jewish women to become guardians of sensitive information and powerful agents of communal authority. Drawing upon a diverse source base, ranging from notarial records and archives of medical colleges, to Jewish communal registers, personal records, midwifery handbooks, and printed rabbinic sources, I show how female Jewish medical practitioners fit into the larger landscape of medical practice in early modern Europe, as well as the ways that Jewish communal structures carved out unique roles for Jewish midwives during this period. Employing methods from the history of science, gender studies, and Jewish history, my study shows that Jewish midwives became part of an international system of scientific communication, whose content flowed between vernacular and elite practitioners. This dissertation thus sheds new light on the ways in which the inclusion of women as subjects, and gender as a lens, presents a landscape of knowledge-making and transmission whose boundaries are more expansive.

description: We study the minimal class of exact solutions of the Saffman-Taylor problem with zero surface tension, which contains the physical fixed points of the regularized (non-zero surface tension) problem. New fixed points are found and the basin of attraction of the Saffman-Taylor finger is determined within that class. Specific features of the physics of finger competition are identified and quantitatively defined, which are absent in the zero surface tension case. This has dramatic consequences for the long-time asymptotics, revealing a fundamental role of surface tension in the dynamics of the problem. A multifinger extension of microscopic solvability theory is proposed to elucidate the interplay between finger widths, screening and surface tension.

description: This thesis analyzes Joan Rivers through a feminist disability lens. In the first chapter of this thesis, I examine Rivers’s comedy. I claim that through disability drag, Rivers was able to create a comedic persona that is incongruent with her own. In the second chapter I analyze Rivers’s relationship with cosmetic surgery. Although Rivers used cosmetic surgery as an empowering form of identity-crafting to achieve cosmetic beauty, it proved to be an unsustainable project that turned her into a freak of sorts. And finally in the third chapter, I view the red carpet as the modern day freak show, with Rivers as its carnival barker. In the same way that she verbally de-faced herself through disability drag, then physically de-faced herself through cosmetic surgery, she de-faced celebrities in Hollywood on the red carpet. In this spectacle of de-facement, Rivers democratized disability in order to make her highly-artificial face normal.Joan Rivers created red carpet culture. Her impact on 21st century popular culture was pervasive: no matter the status of the celebrity, they were subjected to Rivers’s gaze. It is important to analyze Rivers through a disability lens because ultimately, through her acidic commentary she was able to disable celebrities in Hollywood with her words. And through my analysis, I prove that Rivers first used verbal de-facement on herself, before she used it on others. Rivers started her career by first verbally de-facing herself in her comedy, then she literally de-faced herself through her use of cosmetic surgery, and finally, she turned her verbal knife outward to de-face celebrities on the red carpet: Joan Rivers created and perpetuated a spectacle of de- facement.

description: This dissertation demonstrates that German and Yiddish literature about Jews from the turn of the twentieth century until after the Holocaust is characterized by several discourses and tropes borrowed from contemporary ethnography, anthropology, and folklore studies. The influence of these disciplines is manifest in the representation of Eastern European Jews as primitive savages, the depiction of the Jewish people as being at risk of extinction, the articulation of the need to salvage European Jewish culture, and the literary conjunction of folklore with contemporary instances of violence against Jews. These motifs are especially prominent in the works of Alfred Döblin, Franz Kafka, and Arnold Zweig in German and S. An-sky in Yiddish. This dissertation identifies the permutations of these ethnographic discourses in German-Jewish and Yiddish literature, opening new avenues of exploration in the study of the literary and cultural construction of Jewish identity in European modernity.
Job Strain and Neck Symptoms in Work-related Musculoskeletal Disorders

description: Work-related musculoskeletal disorders (WMDs) are a major public health problem in terms of the considerable amount of disability, impairment, and associated economic cost. Among these disorders, the occurrence of WMD symptoms of the neck is prevalent and has been associated with significant disability, long periods of sick leave and loss of productivity in occupational settings. Risk factors for WMDs are multifactorial, and studies have typically focused on ergonomic factors. Psychosocial factors in the work environment have been recently considered; however, findings across these studies have not been consistent. Despite the evidence associated with ergonomic factors on the occurrence of WMDs, widespread prevention and treatment efforts have not been successfully implemented. Psychosocial factors such as high psychological demands, low decision latitude and low social support may play a role in WMD occurrence.
The demand-control-support model has been widely used to predict job strain. Particularly for disorders of the neck, job strain seems to play a strong role in their occurrence. The psychosocial work environment and WMDs are listed as research priorities of the National Occupational Research Agenda developed by the National Institute for Occupational Safety and Health.
This cross-sectional study looked at job strain and neck symptoms, while controlling for confounders. This project was carried out on a group of semiconductor manufacturing workers.
The prevalence of neck symptoms was measured by a self-administered questionnaire. A Chinese version of the Job Content Questionnaire was included to assess psychosocial factors and to test the demand-control-support model. An observational checklist was developed and used to assess ergonomic exposures on individual workers' jobs.
The participation rate was 86.5%. The final sample of semiconductor workers consisted of 373 female participants. Their mean age was 28.4 years ranging from 18 to 41 years. The mean length of employment was 4.3 years. The prevalence of symptoms of neck disorders in the semiconductor manufacturing population was 23.9%.
It was concluded that the prevalence rates of neck symptoms of WMDs in this study were high, especially given the very conservative outcome definition that was used. The study findings partially supported the job strain model, showing an increase in prevalence of neck symptoms with psychological and physical job demands; however, association with decision latitude and social support were not supported. Further studies with more comprehensive measurements of work-related psychosocial factors are implicated and effective prevention strategies for neck symptoms of WMDs are suggested.

description: Molecular diagnosis of autosomal dominant acute hepatic porphyrias (AHPs) plays an important role in the management of these disorders. To introduce next generation sequencing (NGS) to the porphyria diagnosis, we designed a panel that contained four genes, ALAS1, HMBS, CPOX and PPOX for mutational analysis of acute intermittent porphyria (AIP), hereditary coproporphyria (HCP) and variegate porphyria (VP). To validate the AHP panel, 30 samples with known pathogenic variants as determined by Sanger sequencing, were analyzed using the Ion PGM™. Among them, nine have so far not been reported. The pathogenic variants were identified and annotated manually in IGV by three individuals who were blinded to the Sanger results. The AHP panel consists of 95 amplicons that covers 92% of the coding region of the four genes. Of the 95 amplicons, 93 had an average read-depth of >500 reads. In 29 of the 30 tested samples, pathogenic variants were correctly identified and annotated. The number of reads from the mutated alleles were approximately 50% of the total. The annotation of a 22-bp duplication with NGS differed from that of Sanger by one nucleotide. NGS showed an advantage in allelic discrimination over Sanger sequencing and was also able to detect a known somatic variant in the HMBS gene. The AHP panel will be applied in the initial diagnosis of new patients. Any sequence variations with a frequency of ≥10% will be confirmed by Sanger sequencing. The cost-effectiveness of a NGS approach for AHP in a diagnostic laboratory needs to be further assessed.
The Development of Prehistoric Settlement on the West Sussex Coastal Plain

description: Sussex Archaeological Collections, 121, 31-44
description: This article examines the evidence for permanent settlement on the Coastal Plain from the Neolithic to the end of the Iron Age. It is suggested that during the Neolithic much of the area was woodland and marsh, providing resources that were used by groups based on settlements on the South Downs. In the Bronze Age, the evidence indicates the beginnings of settlement, though probably on a limited scale. The possibility is raised of a setback to the spread of settlement, which may be linked to the climatic deterioration of 1000-500 B.C. The Iron Age, however, sees a considerable rise in the number of settlement sites (particularly the middle and late Iron Age). This is discussed in the context of the abandonment of the hillforts at Cissbury and the Trundle, and the establishment of a southern Atrebatic oppidum on the Coastal Plain.

The results are related to geometric quantization, to stochastic analysis, and to the quantization of 1+1-dimensional Yang-Mills theory.
Job Satisfaction and Employee Turnover Intention: What does Organizational Culture Have To Do With It?

description: This study explores the relationship between job satisfaction and employee turnover intention in the context of organizational culture, using data from the Quality of Work Life (QWL) module, a sub-section of the General Social Survey (GSS). Job satisfaction, the independent variable, assesses overall job satisfaction, while the dependent variable, turnover intention, measures intent to find a new job, with another employer, within the next year. While organizational culture varies by industry, employer and even by department, it is important in all working environments. Organizational culture influences employee’s job satisfaction, and in prior studies, high job satisfaction has been associated with better job performance. High performing cultures have also been shown to produce excellent results, attract, motivate, and retain talented employees, and adapt readily to change. Job satisfaction is inversely related to turnover intention and low turnover has been shown to increase organizational productivity and performance. This study finds that job satisfaction is inversely associated with turnover intention and that organizational culture moderates the magnitude of this relationship. Sub-group analyses reveal that job satisfaction is more predictive of turnover intention for younger workers. These findings have significant implications for the changing composition of workforce due to the aging population.

description: Analysis of a survey of Scottish farmers (162) confirmed that they do not perceive all types of risk to be equal. Choices with potential negative ethical or health & safety consequences were perceived to be riskier than those that might have negative financial and social outcomes. A negative relationship was found between perceived riskiness and stated likelihood of taking a risky course of action with one exception - where a health & safety harm might arise. The findings could assist the development of behavioural models with greater predictive powers. In addition, the study suggests that risk awareness is not the most limiting factor for improving health & safety in the Scottish farming industry.

description: Value iteration is a fixed point iteration technique utilized to obtain the optimal value function and policy in a discounted reward Markov Decision Process (MDP). Here, a contraction operator is constructed and applied repeatedly to arrive at the optimal solution. Value iteration is a first order method and therefore it may take a large number of iterations to converge to the optimal solution. Successive relaxation is a popular technique that can be applied to solve a fixed point equation. It has been shown in the literature that, under a special structure of the MDP, successive over-relaxation technique computes the optimal value function faster than standard value iteration. In this work, we propose a second order value iteration procedure that is obtained by applying the Newton-Raphson method to the successive relaxation value iteration scheme. We prove the global convergence of our algorithm to the optimal solution asymptotically and show the second order convergence. Through experiments, we demonstrate the effectiveness of our proposed approach.

Closure planning practice and landscape performance at 57 Canadian and U.S. mines
Creators: name: McKenna, Gord
name: Dawson, Richard F.
Publisher: name: The University of British Columbia
Year: 2009

description: A large number of operating, dormant, and abandoned minesites in Canada and the U.S. were visited in 1996 to gather information on closure planning practice and to observe the performance of reclaimed landscapes. Information was compiled from mine tours and through on-site interviews with reclamation and environmental personnel. Most Canadian mines are on the closure path and have completed their first conceptual closure plan, usually in response to new government regulations. However, there is considerable uncertainty regarding several key closure issues including certification, abandonment, long-term residual liability, financial assurance, and numerous technical issues. Most mining landforms are showing good performance in terms of physical stability and revegetation. However, there is some uncertainty regarding the long-term reliability and performance of some landforms, most notably constructed rivers, end-pit lake filling, and tailings slopes. Difficulty in prediction of the long-term performance of closure landscapes has, in part, lead to a certification barrier. Very few mines have requested or achieved certification of reclaimed land, despite the fact that certification is usually the stated objective of reclamation activity. Although most mine reclamation focuses on certification, a more strategic focus is required. The ultimate objective for mine reclamation should be custodial transfer of the land (to the crown or a third party), with certification being one step on the closure path. Due to the concerns about long-term liability for reclaimed sites, a transfership barrier exists and very little reclaimed mine land has been transferred to new owners. Landscape engineering (setting goals, designing for closure, using landforms and vegetation that have sustainable and reliable long-term performance) is perhaps the next major step in mine reclamation practice.

description: This paper completes a series devoted to explicit constructions of finite-dimensional irreducible representations of the classical Lie algebras. Here the case of odd orthogonal Lie algebras (of type B) is considered (two previous papers dealt with C and D types). A weight basis for each representation of the Lie algebra o(2n+1) is constructed. The basis vectors are parametrized by Gelfand--Tsetlin-type patterns. Explicit formulas for the matrix elements of generators of o(2n+1) in this basis are given. The construction is based on the representation theory of the Yangians. A similar approach is applied to the A type case where the well-known formulas due to Gelfand and Tsetlin are reproduced.

description: We discuss some computational problems associated to matched filtering of experimental signals from gravitational wave interferometric detectors in a parallel-processing environment. We then specialize our discussion to the use of the APEmille and apeNEXT processors for this task. Finally, we accurately estimate the performance of an APEmille system on a computational load appropriate for the LIGO and VIRGO experiments, and extrapolate our results to apeNEXT.

John Jay and the Law of Nations in the Diplomacy of the American Revolution

description: My dissertation examines the role of “the law of nations”—as international law was known in the eighteenth-century—in the diplomacy of the American Revolution. My method is to assess the way in which European and American diplomats used this law in a series of negotiations involving Spain, France, Britain, and the United States in a conflict over the Mississippi River. I argue that European statesmen based their conduct on a set of pragmatic norms, derived from precedent, which were known as the customary law of nations. American revolutionaries were generally naïve in their use of this law, having had no prior experience with international affairs. John Jay—the emissary tasked with defending American interests in the Mississippi—was an exception to this rule. Among Jay’s most notable attributes was the tenacity with which he defended the statehood of the United States, and its corresponding right to the privileges and protections afforded by the law of nations. The issue lay at the heart of the conflict over the Mississippi, and Jay’s conduct, I demonstrate, was decisive to its outcome. In my last two chapters I explore the source of Jay’s perspicacity and suggest that he likely derived his understanding of the law of nations from the treatises of Samuel von Pufendorf—a leading proponent of a theoretical version of the law of nations that was popular in intellectual circles at the time. Pufendorf was an authority in “moral philosophy”, or the scientific study of natural moral law; and he defined states as corporate moral persons, whose rights derived from a universal law of sociability. Jay was educated at King’s College in New York City (1760-1764), and the president of King’s, Samuel Johnson, was one of the preeminent authorities in British North America on Enlightenment-era theories of natural law. Johnson gave Pufendorf a central place in his curriculum, and it was Pufendorf’s theories, I argue, combined with the authority with which Johnson imbued them, that lay behind Jay’s use and conception of the law of nations.

description: The Multiple-criteria decision-making (MCDM) method is one of the most important tools used for decision-making problems. It aims at selecting an action that achieves the highest value according to the criteria in the comparison model, and therefore considering that action as the best solution for comparison. The choice of the construction system in construction is one of the complex issues engineers can encounter during their engineering work.
Curvature decompositions on Einstein four-manifolds

description: For Einstein four-manifolds with positive scalar curvature, we derive relations among various positivity conditions on the curvature tensor, some of which are of great importance in the study of the Ricci flow. These relations suggest possible new ideas to study the well-known rigidity conjecture for positively curved Einstein four-manifolds.

description: Reliance on foreign guest workers, rising minimum wages, and corporate social responsibility are three trends emerging within the Florida agricultural economy, particularly among labor-intensive specialty crop farms. These trends are creating higher costs and pushing employers into new management relationships with their farmworkers. On one hand, higher costs compromise the competitive position of agricultural operations. On the other hand, new management strategies could increase overall worker productivity, offset some administrative costs associated with labor management, and create new avenues of market access for their products. The success to which agricultural employers adjust to these trends with cost effective management strategies likely will determine their long-term economic success.
Modified Relativity from the kappa-deformed Poincare Algebra

description: The theory of the $κ$-deformed Poincare algebra is applied to the analysis of various phenomena in special relativity, quantum mechanics and field theory. The method relies on the development of series expansions in $κ^{-1}$ of the generalised Lorentz transformations, about the special-relativistic limit. Emphasis is placed on the underlying assumptions needed in each part of the discussion, and on in principle limits for the deformation parameter, rather than on rigorous numerical bounds. In the case of the relativistic Doppler effect, and the Michelson-Morley experiment, comparisons with recent experiemntal tests yield the relatively weak lower bounds on $κc$ of 90eV and 250 keV, respectively. Corrections to the Casimir effect and the Thomas precession are also discussed.

description: In an era of unprecedented environmental change, there have been increasing ecological and global public health concerns associated with exposure to anthropogenic pollutants. While there is a pressing need to remediate polluted ecosystems, human intervention might unwittingly oppose selection for natural detoxification, which is primarily carried out by microbes. We test this possibility in the context of a ubiquitous chemical remediation strategy aimed at targeting metal pollution: the addition of lime-containing materials. Here, we show that raising pH by liming decreased the availability of toxic metals in acidic mine-degraded soils, but as a consequence selected against microbial taxa that naturally remediate soil through the production of metal-binding siderophores. Our results therefore highlight the crucial need to consider the eco-evolutionary consequences of human environmental strategies on microbial ecosystem services and other traits.

description: Graph convolutional networks (GCNs) are powerful tools for graph-structured data. However, they have been recently shown to be vulnerable to topological attacks. To enhance adversarial robustness, we go beyond spectral graph theory to robust graph theory. By challenging the classical graph Laplacian, we propose a new convolution operator that is provably robust in the spectral domain and is incorporated in the GCN architecture to improve expressivity and interpretability. By extending the original graph to a sequence of graphs, we also propose a robust training paradigm that encourages transferability across graphs that span a range of spatial and spectral characteristics. The proposed approaches are demonstrated in extensive experiments to simultaneously improve performance in both benign and adversarial situations.
