Stable Colored Particles R-SUSY Relics or Not?

R-hadrons are only one of many possible stable colored states that the LHC might produce. All such particles would provide a spectacular, if somewhat unusual, signal at ATLAS and CMS. Produced in large numbers and leaving a characteristic signature throughout all layers of the detector, including the muon chamber, they could be straightforward to discover even with low luminosity. Though such long lived colored particles (LLCPs) can be realized in many extensions of the Standard Model, most analyses of their phenomenology have focused only on R-hadrons. In order to distinguish among the possibilities, fundamental quantum numbers of the new states must be measured. In this paper, we demonstrate how to identify the $SU(3)_C$ charge and spin of such new particles at the LHC.Comment: 11 pages, 7 figure

Promoting the Success of All Students:

In today’s schools, building level administrators are faced with numerous challenges as they attempt to provide leadership that promotes successful learning experiences for all students. Setting the stage for this leadership, the Council of Chief State School Officers organized the Interstate School Leaders Licensure Consortium (ISLLC) in 1996. This consortium was formed for the purpose of developing model standards and assessments for school leaders. The ISLLC’s primary constituency is the state education agencies responsible for the administration of licensure. It included representatives of state agencies/departments of education and professional standards boards, with considerable participation by professional associates

Surviving the First Years: A Principals Guide for Implementing a Quality Special Education Program

In today’s schools, building level administrators are faced with a variety of challenges as they strive to provide leadership that promotes successful learning experiences for all students. Promoting the success of all students is also the foundation of current federal legislation with the No Child Left Behind (NCLB) mandates as well as the Individual with Disabilities Education Act (IDEA). Answering the call of these directives and the goal for all students to experience success, building level principals must have fundamental knowledge of special education programs and services. However, research indicates that principal preparation course work may not target special education leadership and responsibilities (DiPaulo and Tschanned-Moran 2003). Further studies, such as work done by Lasky and Karge (2006), examined principal preparation programs and found the need for increased training in the area of special education during the preservice phase. Therefore, with little emphasis during the principal preparation experience in providing leadership at the building level in the area of special education, many beginning principals find themselves challenged on a daily basis. Learning on-the-job becomes the starting point for all fundamental knowledge regarding special education leadership

Supporting New School Leaders Through Mentoring

Mentoring may best be defined as “a process where one person provides individual support and challenge to another professional (Bush, 2009, p.379). The importance of mentoring new teachers and administrators has long been recognized. For example, since 2000 more than half of the states have passed laws requiring mentoring of new principals (Daresh, 2004; Spiro, Mattis, & Mitgang 2007). Most of these laws have required mentoring in the first two years of practice. Grissom & Harrington (2010) found under the mentorship model, a more experienced principal mentor provides the support, guidance, advice and sounding board as the new principal becomes acclimated to the position

La Société pour l’étude des Langues Romanes vue du lycée de Montpellier et de l’Académie d’Aix-en-Provence : Tourtoulon, Boucherie et le proviseur Foncin

En 1897, dans son Discours de réception à l’Académie d’Aix, Charles de Tourtoulon rendait hommage à son prédécesseur décédé Joseph Foncin. Il fut reçu par Charles Soubrat, un ancien condisciple. Leurs deux discours, réunis dans une même brochure, sont à la base de cet article. Foncin, proviseur au lycée de Montpellier jusqu’à mi-1868, s’entretenait avec le professeur Anatole Boucherie lorsque la Société pour l’étude des langues romanes (SELR) se préparait. Dès sa création en 1869, il y avait adhéré. La précision des données permet d’observer la procédure que Tourtoulon avait suivie lors des recherches de la limite oc/oïl en 1873, le moment fort de sa vie de linguiste. La démarche scientifique expérimentale du récipiendaire est décrite, de même que son travail d’historien en vue d’écrire une histoire totale, autour du roi Jacques d’Aragon. Dans son discours, il proposait une méthode de travail à des amateurs qui voudraient étudier le parler de leur village tandis que des académiciens provençaux étaient surpris que leur confrère et linguiste Gaston Paris ait nié en 1888 la spécificité de la langue d’oc. On note également comment les diverses préoccupations et les engagements de l’érudit Tourtoulon ont rythmé sa vie, notamment dans le Félibrige. La trajectoire de Joseph Foncin, connue par plusieurs sources, permet d’éclairer son soutien à la SELR. Agrégé de grammaire, Lorrain ayant exercé dans l’Est puis le Midi de la France, il avait été en contact avec différentes langues et dialectes, comme d’autres jeunes agrégés nommés loin de leur lieu d’origine. Après ses mariages successifs, il avait fait l’essentiel de sa carrière dans le Midi. Il est représentatif de ces professeurs et éducateurs ayant vu l’intérêt de la SELR et des projets qu’elle portait avec sa revue pour la connaissance de la langue d’oc, autour de Boucherie et de Tourtoulon entre autres.In 1897, in his reception speech at the academy of Aix-en-Provence, Charles de Tourtoulon paid tribute to his deceased predecessor Joseph Foncin. Charles Soubrat, his former fellow student, pronounced then the welcome speech. The two speeches, gathered in a single brochure, are the base of the present article. Foncin, proviseur of the lycée of Montpellier until mid–1868, and Professor Anatole Boucherie were in very good termes while the Société pour l’étude des langues romanes (SELR) was getting started. From its creation in 1869 Joseph Foncin had joined it. Precise data make it possible to observe the procedure Tourtoulon had followed during the research of the oc/oïl boundary in 1873, the highest point of his life as a linguist. The methodology used througout this investigation is precisely explained. His experimental scientific approach is thus described, as well as his work as a historian with a view to writing a complete history about King James of Aragon. In his speech, he proposed a working method to amateurs who would like to study the language of their village, while Provençal academics were surprised that their colleague and linguist Gaston Paris had denied in 1888 the specificity of the langue d'oc. We also note how the various preoccupations and commitments of the scholar Tourtoulon punctuated his life, particularly in the Félibrige. The evolution of Joseph Foncin, known by several sources, sheds light on his support for the SELR. As an Agrégé de grammaire, born in Lorraine but having worked in the East and then the South of France, he had been in contact with different languages and dialects, as had other young agrégés named far from their place of origin. After his successive weddings, he had spent most of his career in the South of France. He is representative of those teachers and educators who saw the interest of the SELR and the projects it carried with its journal (la RLaR) for the knowledge of the langue d'oc, in the path of Boucherie and Tourtoulon among others

The ethylene precursor ACC affects early vegetative development independently of ethylene signaling

The plant hormone ethylene plays a pivotal role in virtually every aspect of plant development, including vegetative growth, fruit ripening, senescence, and abscission. Moreover, it acts as a primary defense signal during plant stress. Being a volatile, its immediate biosynthetic precursor, 1-aminocyclopropane-1-carboxylic acid, ACC, is generally employed as a tool to provoke ethylene responses. However, several reports propose a role for ACC in parallel or independently of ethylene signaling. In this study, pharmacological experiments with ethylene biosynthesis and signaling inhibitors, 2-aminoisobutyric acid and 1-methylcyclopropene, as well as mutant analyses demonstrate ACC-specific but ethylene-independent growth responses in both dark- and light-grown Arabidopsis seedlings. Detection of ethylene emanation in ethylene-deficient seedlings by means of laser-based photoacoustic spectroscopy further supports a signaling role for ACC. In view of these results, future studies employing ACC as a proxy for ethylene should consider ethylene-independent effects as well. The use of multiple knockout lines of ethylene biosynthesis genes will aid in the elucidation of the physiological roles of ACC as a signaling molecule in addition to its function as an ethylene precursor

Attenuating through Aid the Vulnerability to Price Shocks

The purpose of this paper is to examine what kind of global measures may be efficiently implemented to help the developing countries to face price shocks, avoiding the past failures, which needs to take into account the long term trend of the markets. Firstly, we recall the nature of the vulnerability to price shocks: this legitimates to make the dampening of these shocks a reasonable goal for the development cooperation policy. Then, we consider the rationality of some international schemes of insurance or of guarantee which could be implemented through international assistance for countries facing price shocks: this assistance should be provided on a macroeconomic level, in particular through debt management, and on a microeconomic level, for instance through an insurance for the producers. The general principle underlying our proposals is that international assistance can enable developing countries to face price shocks, while taking into account the market signals, by offering a guarantee to these countries provided they respect some management rules.

Développer des projets d’agriculture urbaine avec la méthode Meth-Expau®

Today, urban agriculture appears to be a lever for the ecological transition of cities and a tool for education in sustainable food. Many urban development actors are setting up projects on their territories: collective gardens, eco-grazing, participative micro-farms, mushroom beds, beehives, etc. However, the implementation of this type of project raises many questions about their relevance and feasibility in the areas concerned. What are the expectations of the different actors and inhabitants? What types of project can be implemented? What surface area is necessary? How to set up a shared garden or a micro-farm? This guide proposes a methodology based on the experience of the Exp'AU research office (Expertises en agricultures urbaines, under the aegis of AgroParisTech Innovation), which since 2015 has been carrying out missions to support local actors in setting up urban agriculture projects. The proposed methodological itinerary is structured in three steps and guides the user step by step in his approach, even without specific knowledge related to this field. This book is intended for owners and managers of urban land (local authorities, landlords, developers, planners) who wish to set up urban agriculture projects, whether commercial (urban farms, eco-grazing) or non-commercial (shared gardens, chicken coops, etc)
