Le processus de décision naturaliste en environnement big data : le cas des forces de Police au sein d’un Centre d’Information et de Commandement (CIC)
Authors: Godé Cécile , Lebraty Jean-Fabrice , Vazquez Jordan
Published: January 2020

L’approche Naturalistic Decision Making (NDM) constitue un paradigme de recherche dominant lorsqu’il s’agit d’analyser le processus de décision d’experts évoluant en environnement dynamique, confrontés à des problèmes faiblement structurés et exigeant une résolution rapide. Depuis une dizaine d’années, le développement des technologies de l’information contribue à enrichir l’approche NDM. S’inscrivant dans cette perspective, une étude de cas qualitative inductive est développée pour comprendre comment des policiers experts d’un Centre d’Information et de Commandement (CIC) prennent des décisions en environnement big data. Le CIC produit quotidiennement un volume important de données véloces, variées et nécessitant d’être vérifiées, que les policiers assemblent en situation à partir de dispositifs technologiques non intégrés. L’analyse du cas met l’accent sur deux phases du processus de décision en environnement big data : une phase amont de conscience de la situation, pleine ou incomplète selon les situations, et une phase de reconnaissance immédiate. Ces résultats permettent de proposer un modèle intégré du processus de décision naturaliste, appliqué au cas des policiers du CIC en environnement Big data.
Agentes artistiques : des faiseuses de noms et de rémunérations
Authors: Naudier Delphine
Published: January 2020

Cet article a pour objet d’appréhender la fabrique des rémunérations des personnels artistiques (comédien·nes, scénaristes et cinéastes) négociées par les agentes artistiques, intermédiaires qui représentent les intérêts de ces derniers auprès des employeurs/financeurs de films. En ouvrant l’enveloppe des rémunérations des artistes, on analysera la manière par laquelle le « rapport de production symbolique » organise la polarisation de ce commerce du travail. On saisira d’abord quelles dispositions sociales, commerciales et culturelles des agentes artistiques sont investies dans cette activité, on identifiera ensuite quelles conventions et stratégies et quels rapports de pouvoir sont au cœur des mécanismes de tarification et de valorisation du « nom » des artistes, pour enfin comprendre comment ce commerce du travail, régi par une économie de projets et par une économie de la singularité, est structurellement constitutif de l’individualisation des rémunérations.
Quantifier les inégalités salariales
Authors: Coron Clotilde
Published: January 2020

Les obligations des entreprises françaises en matière d’égalité professionnelle ont récemment fait l’objet d’un important renforcement, notamment en ce qui concerne l’égalité salariale entre les femmes et les hommes, avec la promulgation de la loi de 2006 sur la réduction de l’écart salarial. Le sujet de l’égalité salariale est propice à la quantification. Pour autant, les outils de quantification mobilisés par les entreprises peuvent être insuffisants pour analyser en profondeur l’écart salarial et identifier des leviers d’action. En partant du cas d’une grande entreprise française pourtant relativement outillée sur le sujet, nous montrons que la profusion des indicateurs, si elle permet de diagnostiquer les inégalités, à la fois aux yeux des syndicats et de la direction, ne permet pas totalement de comprendre les causes de l’écart salarial ou ses différentes composantes. Elle peine donc à mettre en place les leviers pour le réduire. L’introduction d’une méthodologie plus sophistiquée visait à faciliter l’identification de ces leviers, mais a surtout eu comme conséquence un risque de justification des inégalités salariales.
La fabrique de l’intérêt collectif
Authors: Wagner Anne Catherine
Published: January 2020

Au sein des Scop (Sociétés coopératives et participatives), les salariés sont aussi les principaux propriétaires de l’entreprise ; ils sont rémunérés au titre de leur travail et de leur participation financière. Ces entreprises mettent en avant la dimension collective de leur fonctionnement. La recherche du profit y est subordonnée à l’impératif de coopération. L’article se penche sur la place des pratiques de rémunération dans la construction d’un intérêt commun qui doit souder les coopérateurs. S’appuyant sur une enquête auprès de trois coopératives industrielles, il montre à quelles conditions les dispositifs de rémunération du capital et du travail peuvent contribuer à constituer des collectifs qui reposent sur des principes de cohésion contrastés. Les coopératives conduisent ainsi à poser la question des conditions de possibilité de la mise en place et de l’acceptation de systèmes de rémunérations relativement autonomes par rapport au « marché ».

Authors: Anisimova Tatyana Ivanovna , Sabirova Fairuza Musovna , Shatunova Olga Vasilyevna
Published: January 2020

In today's digital society and economy, professions associated with high technologies are becoming increasingly in demand: programmers, system en-gineers, IT specialists, biotechnologists, project leaders, etc. In this regard, school graduates are required not just good knowledge of school subjects, but also knowledge interdisciplinary, the formation of which is a long pro-cess, starting as early as school, and only traditional methods are indispensa-ble. One of these innovative technologies is STEAM education. To imple-ment the concept of STEAM-education, the system of pedagogical education is tasked with training relevant personnel with the necessary competencies, among which the most relevant are meta-subjects and design and research skills. In our opinion, one of the possible innovations in the preparation of teachers for STEAM education is the inclusion of the “Robotics” discipline in the content of training future teachers of physics, mathematics, technolo-gy, visual arts, and others. The authors conducted a survey among future teachers studying at the Faculty of Mathematics and Natural Sciences and Engineering and Technology Faculties of the Elabuga Institute of Kazan Fed-eral University, showed that the problem of training graduates of general ed-ucational institutions to the challenges of the new time is more relevant than ever. Only 18% of respondents are aware of the existing the world and the country STEM and STEAM education programs, 15% of the students sur-veyed believe that they are ready to implement project activities STI and on-ly 10% of students believe that they are ready to lead project activities. These data indicate that not only the problem of teachers' readiness to im-plement new educational programs, but also the problem of preparing future teachers to implement practice-oriented educational activities based on the formation of design and research competencies, is coming to the fore.

Published: January 2020

this is the extended research work where we tried to add more sections in Quality instruments to their role in achieving interoperability in e-learning and quality. In this paper we included more reference models such as experiences of Quality instruments affected by demographic criteria. In Higher education systems E-Learning faces two major challenges, first to ensure the interoperability of E-Learning (IEL) and secondly, developing quality learning through e-Learning. This research studies the concept, scope and dimensions of interoperability of E-Learning in education with special reference to King Khalid University then the connection and interdependence between with quality development. To impart learning and teaching through E-learning, KKU has adopted Learning Management Services (LMS) through Blackboard. The university has three types of learning and teaching methods; full online, Blended and Supportive. In this paper we have described the dimensions of quality and the standards of E- Learning for the objectives of IEL and quality development (QD) in KKU. The research is based principally on secondary data observed from KKU E-Learning deanship. Also sample of 20 E-Learning experts at KKU were given closed ended as well as semi closed questionnaires for evaluating the assurance of IEL and QD. These experts are mainly certified online facilitators and admin staff. Results provide the verification of application and presence of IEL and assured the QD process in KKU in imparting knowledge.

Published: January 2020

The purpose of this research is to explore the students’ perception about the implementation of blended learning approach (BLA) in inclusive education course. Thirty (30) students participated in this research. The data collection was done by open interview to know students’ perception about the implementation of blended learning. The interview results were analyzed using context analysis techniques. Based on the data analysis, there are four catego-ries of students' attention, namely: display of learning management system (LMS); accessibility; the benefits and sustainability. Student perceptions of each category are: the LMS display on the web of 50.53% is appropriate and simple, but must be modified to make it easier for students to understand. The negative perception about accessibility of 69.57% indicates that internet access to the web is still unstable and slow. Positive perception about BLA benefit of 66.94% indicates good benefits to students especially in terms of adding learn-ing experiences, knowledge, variations of learning models and learning more flexible and independent. A positive perception of BLA sustainability of 66.18% indicates should be continued because it can increase students' learning interest, learn more modern, flexible and independent.
An Introduction to Fuzzy Matrices
Authors: Pal Madhumangal
Published: January 2020

Fuzzy matrices are successfully used when fuzzy uncertainty occurs in a problem. Fuzzy matrices have become popular in the last two decades. In this chapter, two new binary fuzzy operators, ⊕ and ⨀, for fuzzy matrices are introduced. Several properties on ⊕ and ⨀ are presented here. Also, some results on existing operators along with these new operators are presented. In this chapter, Hamming and Euclidean distances are introduced for fuzzy matrix and investigated a number of properties. Here, one application is mentioned to recognize a printed character automatically with the help of Hamming distance. The proposed method is applicable when the characters are printed with same font, same size, and same shape. In the case of hand-written characters, the proposed method is also equally effective if it is modified. A lot of works have been done in fuzzy matrices, but there is a huge scope to work with these matrices.
Multiset Approach to Algebraic Structures
Authors: P. Suma , John Sunil Jacob
Published: January 2020

This chapter explores the various algebraic structures that exist in the fuzzy set environment in a multiset context. The authors have also established analogs of groups, rings, and ideals of sets in multiset environment. The conditions under which a multiset that is derived from a group becomes a multiset group (shortly mset group) and that derived from a ring to become a multiset ring (shortly mset ring) have been mentioned. The distinguishing between multiset subring and multiset ideals has been discussed on in the chapter. The authors have also delved into properties such as intersection and union of mset groups, mset rings, and ideals.
Intuitionistic Fuzzy Soft Ideals
Authors: Khalil Shuker
Published: January 2020

The basic notions of soft sets theory are introduced by Molodtsov to deal with uncertainties when solving problems in practice as in engineering, social science, environment, and economics. This notion is convenient and easy to apply as it is free from the difficulties that appear when using other mathematical tools as theory of theory of fuzzy sets, rough sets, and theory of vague sets. The soft set theory has recently gaining significance for finding rational and logical solutions to various real-life problems, which involve uncertainty, impreciseness, and vagueness. The concepts of intuitionistic fuzzy soft left almost semigroups and the intuitionistic fuzzy soft ideal are introduced in this chapter, and some of their basic properties are studied.

Published: January 2020

The chapter assesses the profile of volunteerism in Saudi Arabia, particularly the Al-Jubail Volunteer Club and its impact to society. One-hundred ninety (190) members of the club were the respondents of the study. Descriptive research design was utilized to gain accurate profile of the situation. It is found out that the demographic profile of volunteers coincides with some previous studies in terms of age bracket and occupation. Community concern motivated volunteers to participate. Volunteers perceived volunteering as a worthwhile activity. It is something that can improve and imply positive impact on their personal development. It is further concluded, that volunteering can help in over-all development of its members and society as well. Thus, volunteerism is the fundamental demonstration of citizenship, a method for battling social barring, and an imperative benefactor to the conveyance of good quality public service.
Roquin-1 Regulates Macrophage Immune Response and Participates in Hepatic Ischemia–Reperfusion Injury
Authors: Zheng Lei , Ling Wei , Zhu Deming , Li Zhi , Kong Lianbao
Published: January 2020

With the development of liver surgery, ischemia–reperfusion (IR) injury has received increasing attention. Roquin-1 has been shown to play an important role in innate immune and immune balance. We demonstrate that Roquin-1 expression increased at 1 h after IR and then decreased in C57B/L mice. The immunofluorescence double-label showed that Roquin-1 was mainly expressed in macrophages (mø). Furthermore, we used clodronate liposomes to remove mø, and injected the bone marrow–derived mø (BMDM) through the tail vein in 1 h before IR. We found that liver IR injury was aggravated by Roquin-1 interference. The results of PCR and ELISA suggested that after interference with Roquin-1, mø increased toward M1 and decreased toward M2. Then, interference with Roquin-1 promoted the polarization of mø to M1 and inhibited the polarization of M2. By Western blot technology and AMPKα and mTOR inhibitors, we found that Roquin-1 promotes the phosphorylation of mTOR and STAT3 by inhibiting the phosphorylation of AMPKα. We used AICAR to activate AMPKα in mø and found that the level of ubiquitination of AMPKα was decreased after activation of AMPKα. Furthermore, by bioinformatics methods, we identified potential ubiquitination sites on AMPKα. By the point mutation experiments in vitro, we confirmed that the ubiquitination of these sites is regulated by Roquin-1. Meanwhile, Roquin-1 interference inhibited the activation and function of AMPKα. This topic describes the protection of liver IR injury by Roquin-1 and discusses its main mechanism for regulating AMPKα activity through ubiquitination and affecting the polarization of mø.

Published: January 2020

In this study, we generated a tkl1 deletion mutant in the Toxoplasma gondii type 1 RH (RHΔtkl1) strain and tested the protective efficacies of vaccination using RHΔtkl1 tachyzoites against acute, chronic, and congenital T. gondii infections in Kunming mice. Mice vaccinated with RHΔtkl1 mounted a strong humoral and cellular response as shown by elevated levels of anti–T. gondii–specific IgG, IL-2, IL-12, IFN-γ, and IL-10. All RHΔtkl1-vaccinated mice survived a lethal challenge with 1 × 103 tachyzoites of type 1 RH or ToxoDB#9 (PYS or TgC7) strain as well as 100 cysts or oocysts of Prugniuad strain. All mock-vaccinated plus infected mice have died. Vaccination also protected against cyst- or oocyst-caused chronic infection, reduced vertical transmission caused by oocysts, increased litter size, and maintained body weight of pups born to dams challenged with 10 oocysts on day 5 of gestation. In contrast, all mock-vaccinated plus oocysts-infected dams had aborted, and no fetus has survived. Vaccinated dams remained healthy postinfection, and their brain cyst burden was significantly reduced compared with mock-vaccinated dams infected with oocysts. In vivo depletion of CD4+ T cells, CD8+ T cells, and B cells revealed that CD8+ T cells are involved in the protection of mice against T. gondii infection. Additionally, adoptive transfer of CD8+ T cells from RHΔtkl1-vaccinated mice significantly enhanced the survival of naive mice infected with the pathogenic strain. Together, these data reaffirm the importance of CD8+ T cell responses in future vaccine design for toxoplasmosis and present T. gondii tkl1 gene as a promising vaccine candidate.

Homogeneous populations of mature differentiated primary cell types can display variable responsiveness to extracellular stimuli, although little is known about the underlying mechanisms that govern such heterogeneity at the level of gene expression. In this article, we show that morphologically homogenous human endothelial cells exhibit heterogeneous expression of VCAM1 after TNF-α stimulation. Variability in VCAM1 expression was not due to stochasticity of intracellular signal transduction but rather to preexisting established heterogeneous states of promoter DNA methylation that were generationally conserved through mitosis. Variability in DNA methylation of the VCAM1 promoter resulted in graded RelA/p65 and RNA polymerase II binding that gave rise to a distribution of VCAM1 transcription in the population after TNF-α stimulation. Microarray analysis and single-cell RNA sequencing revealed that a number of cytokine-inducible genes shared this heterogeneous response pattern. These results show that heritable epigenetic heterogeneity is fundamental in inflammatory signaling and highlight VCAM1 as a metastable epiallele.
Late recurrence of a papillary thyroid carcinoma 37 years after hemithyroidectomy: Solitary, left cervical lymph node metastasis evident on fluorodeoxyglucose positron-emission tomography/computed tomography images revealing nodular uptake
Authors: Kunogi Hiroaki , Naoi Yutaka , Matsumoto Toshiharu , Ozaki Yutaka
Published: January 2020

In patients with well-differentiated papillary thyroid carcinoma (PTC), late recurrence is very rare. It is unusual that 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (PET/CT) shows hypermetabolic lesions in patients with well-differentiated PTC metastases. We demonstrate an exceptional case exhibiting a first relapse 37 years after hemithyroidectomy to treat PTC. Recurrent metastasis of a PTC should be considered as a differential diagnosis even if the elapsed time from the initial treatment is great. A left cervical lymphadenopathy, which exceptionally exhibited a hypermetabolic lesion on PET/CT, should be considered a metastatically well-differentiated PTC.
Hyperbolicities in CAT(0) cube complexes
Authors: Genevois Anthony
Published: January 2020

This paper is a survey dedicated to the following question: given a group acting on a CAT(0) cube complex, how to exploit this action to determine whether or not the group is Gromov/relatively/acylindrically hyperbolic? As much as possible, the different criteria we mention are illustrated by applications. We also propose a model for universal acylindrical actions of cubulable groups, and give a few applications to Morse, stable and hyperbolically embedded subgroups.

The impact of data on EU merger control
Authors: Whitfield Stephen , Brown Richard J. , Rogers Ingrid
Published: January 2020

There has been an increased focus of the European Commission and numerous national competition authorities on data-related mergers, which also fits more generally in the context of a broader global competition law focus on the ‘FAANGs’ (i.e., Facebook, Apple, Amazon, Netflix and Google) and the wider tech sector. This article considers the impact of data on EU merger control and explores the theories of harm and legal frameworks which have been applied and developed in considering data-related competition concerns, in particular the notable developments in the Commission's recent consideration of Apple's acquisition of Shazam. The article considers that the impact of these developments is that data-related mergers should no longer be assessed by reference to traditional economic indicators such as market shares and concentration levels only, but rather also in the context of the broader global competition law focus on big tech.
3D survey for the archaeological study and virtual reconstruction of the “Sanctuary of Isis” in the ancient Lilybaeum (Italy)
Authors: Fazio Leonarda , Lo Brutto Mauro
Published: January 2020

In recent years, the use of three-dimensional (3D) models in cultural and archaeological heritage for documentation and dissemination purposes has increased. New geomatics technologies have significantly reduced the time spent on fieldwork surveys and data processing. The archaeological remains can be documented and reconstructed in a digital 3D environment thanks to the new 3D survey technologies. Furthermore, the products generated by modern surveying technologies can be reconstructed in a virtual environment on effective archaeological bases and hypotheses coming from a detailed 3D data analysis. However, the choice of technologies that should be used to get the best results for different archaeological remains and how to use 3D models to improve knowledge and dissemination to a wider audience are open questions.

This paper deals with the use of terrestrial laser scanners and photogrammetric surveys for the virtual reconstruction of an archaeological site. In particular, the work describes the study for the 3D documentation and virtual reconstruction of the “Sanctuary of Isis” in Lilybaeum, the ancient city of Marsala (southern Italy). The "Sanctuary of Isis" is the only Roman sacred building known in this archaeological area. Based on the survey data, it has been possible to recreate the original volumes of the ancient building and rebuild the two best-preserved floors –a geometric mosaic and an opus spicatum– for a first digital reconstruction of the archaeological complex in a 3D environment.
3D modelling of a 15th century city gate of Rennes: Portes Mordelaises
Authors: Barreau Jean-Baptiste , Esnault Elen , Foucher Jérôme , Six Manon , Le Faou Cécile
Published: January 2020

The Portes Mordelaises, remnants of the medieval city walls of Rennes, France, has been the subject of several archaeological excavations until 2017. From these excavations, we created a three-dimensional (3D) model of the site reconstructed as it would have appeared during the 15th century, including the surrounding plus the interiors of its famed towers. Once our efforts and results were officially recognised as being of national interest by the French Ministry of Culture and Communication, Department of Heritage and the National Museum Service of France, we presented our virtual model reconstruction in an exhibition curated by the Museum of Bretagne, entitled "Rennes, les vies d'une ville" (Rennes, the Lives of a City). This approach to 3D reconstruction of the site served to further study Rennes’ origins, its construction, organisation, as well as its historic relationship to surrounding territories. The main objective of this work was to investigate, using of a significant and complex archaeological site as proof of concept, how the digitalisation of an existing structure, the modelling of its hypothetical structures, and the interactions with its virtual spaces enabled the general public to provide critical feedback, and enhance archaeological knowledge and evaluation of such sites. This reconstruction was carried out under a West Digital Conservatory of Archaeological Heritage project, whose mission is to support and advise archaeologists in the production and exploration of 3D archaeological datasets using the latest digitisation, modelling, and virtual reality (VR) techniques. Through a complex but repeatable process, using the valuable data provided by various excavations, in addition to new information provided by the 3D digitalisation itself, we produced a 3D model, fully satisfactory to rigorous scientific standards, which was then incorporated into a VR space ready for diffusion to the general public. Furthermore, the fact that 45850 visitors were welcome to experience our 3D model at an exhibition in a city the size of Rennes proved to be a significant success.
Contra uma moralidade das mulheres: a crítica de Joan Tronto a Carol Gilligan
Authors: Spinelli Letícia Machado
Published: January 2020

Esse artigo pretende reconstruir a crítica de Joan Tronto ao modelo da ética do cuidado de Carol Gilligan. A análise de Tronto compreende, por um lado, que o cuidado não se restringe a uma moral feminina, mas é possível verificar sua prática em grupos em condição de subordinação, e, por outro (em consequência disso), que não se pode teorizar o cuidado sem o aporte do social. Sob esse aspecto, Tronto observa na análise de Gilligan um discurso essencialista e elitista que pretende universalizar a experiência do cuidado a partir de grupos hegemônicos.
Students’ Perceptions of Agriscience when Taught Through Inquiry-Based Instruction
Authors: Thoron Andrew C. , Burleson Sarah E.
Published: January 2020

United States science scores have remained stable over the past 12 years, and as a result secondary school students have been deemed less proficient than international peers. Additionally, there has been increased pressure for accountability from both teachers and students. This highly competitive performance-based classroom environment has threatened student motivation. Due to this, many have moved away from an emphasis on rote memorization and lessened the threat of performance testing by using inquiry and problem solving strategies as a way to provide more autonomy in the classroom. Agricultural education has joined the movement in providing autonomy in the classroom through inquiry-based teaching methods. This study investigates the perceptions of school-based agriscience students toward agriscience and inquiry-based instruction when taught through inquiry-based instruction. The perceptions of 170 secondary agriscience students who responded to the questionnaire indicated more favorable attitudes toward agriscience. Participants also had positive responses to items regarding agriculture’s importance to society, and influence in their daily lives. It is recommended that inquiry-based instruction be utilized in the agriscience classroom to promote student learning and motivation. Further investigations on the impacts of student motivation in the classroom when inquiry-based instruction is utilized in school-based agriscience education should be investigated.
Are Agriculture Students More Career Ready? A Comparative Analysis of Illinois Juniors
Authors: Mouser David M. , Sheng Zhaohui , Thoron Andrew C.
Published: January 2020

In a state facing broad budget shortfalls, agricultural education programs have to show their value in relation to other key subject areas, such as math and reading. The best agricultural education programs follow a three-component model of instruction, including classroom experience, leadership development through FFA involvement, and an experience-based activity through a Supervised Agricultural Experience program (SAE). Each year state FFA associations recognize top chapters with gold or silver emblem designations. In this quantitative study, we compare eleventh grade Illinois agriculture students from Gold and Silver Emblem FFA chapters to all other Illinois eleventh-grade students on ACT WorkKeys assessments designed to measure levels of
career readiness. In addition, we also provide a comparison of Illinois agriculture students from Gold and Silver Emblem FFA chapters to all juniors tested from the same schools. The assessment results indicated that the selected group of agriculture students are more career ready than their peers, particularly in the area of math.
Examining University-level Agricultural Students' Safety Climate Attitudes in the Agricultural Mechanics Labratory
Authors: Chumbley Steven "Boot" , Hainline Mark S. , Wells Trent
Published: January 2020

Educational laboratory management is a paramount issue in agricultural education settings. Agricultural mechanics laboratories are found in many agricultural education programs. One of the most important issues an instructor in agricultural education settings faces is safety in the agricultural mechanics laboratory. Identifying and cultivating a culture of safety in students early on is key to reducing injuries and accidents. The purpose of this study was to gauge safety climate attitudes within a university-level agricultural mechanics laboratory. The population for this study was university-level agricultural students who were enrolled in two agricultural mechanics courses. Through the lens of Ajzen’s (1991) theory of planned behavior, the students’ safety climate attitudes were assessed by the Safety Climate Attitudes Questionnaire. The highest mean scores were found in the constructs of Personal Motivation for Safe Behavior and Positive Safe Practices. The lowest mean scores were found within the constructs of Risk Justification and Fatalism. We recommend that further study of this topic be conducted in additional agricultural education settings to understand students’ attitudes toward safety in laboratory environments.
Preservice Teacher Perceptions of the Role an Agriculture Teacher During Their Early Field Experience
Authors: Smalley Scott W. , Rank Bryan D.
Published: January 2020

School-based agriculture teachers (SBAE) hold many roles inside and outside of the school. Identifying and understanding the many roles an agriculture teacher may have in their career is an important part of an early field experience (EFE). In this study, EFE students (n = 18) submitted written reflections focused on the role of an agriculture teacher. Open coding of the preservice teacher reflections revealed five themes including work-life balance, public relations, role of an FFA advisor, student success, and school responsibilities. Codes within these five themes indicate a student-centered approach among agriculture teachers. Additionally, EFE students described many school responsibilities outside of the agriculture program that may contribute to a work-life imbalance among agriculture teachers. It is recommended that teacher education programs have current practicing teachers be engaged as part of the preparation process for pre-service students to learn about agriculture teacher roles. Consideration needs to be taken when selecting EFE sites to ensure students are receiving a quality experience, which reinforces the teacher preparation program objectives.
Examining the Reasons Agricultural Education Teaching Graduates Choose to Enter, Leave, or Stay in the Teaching Profession

With half of all school-based agricultural education teachers leaving the profession within their first six years, the need is greater than ever for post-secondary graduates to enter and stay in the profession. This study explored potential influencers on graduates’ career decisions, focusing on identifying potential reasons they chose to not enter, leave, or stay in the profession. The target population was Montana State University Agricultural Education Teaching graduates who completed their degree program between May 2005 and May 2016 (N = 58). Respondents’ post-graduation career paths fell into five pre-determined groups, which were then narrowed into three broader groups: never entered, leavers, and currently teaching. Similar to previous research, competitive salaries outside education, being recruited for another position, and an inadequate work-life balance emerged as the largest factors in respondents’ decisions to not enter the profession. Somewhat contradictory, adequate work-life balance; stable contracts with a competitive salary; and positive student, school, and community connections emerged as top reasons to remain in the profession. Since the most common reasons for not entering/leaving the profession revolved around careers outside of education, primarily the salaries of those positions, it is recommended that stakeholders explore alternative methods of providing supplemental funding for these salaried positions.

An ever-changing world of education has led to growing demand for teachers to remain competent educators. For school districts to enhance teacher effectiveness, professional development workshops must be tailored to the specific needs of educators. To further complicate the issue, in-service needs of teachers are ever growing and changing based on experience. The theoretical foundation of this study was Knowles Theory of Andragogy. Per the theory, adult learners are motivated to learn when they feel intrinsic value or realize the personal gain from the learning activity. The central drive for this study was to determine what Louisiana agriculture teachers desired in terms of classroom- based professional development, thereby giving these adult learners a hand in planning professional development activities. The results from this study indicate that there are dissimilar professional development needs based on years of teaching experience. Per the conclusions, we recommend the results of this study be shared with state agricultural education staff, university faculty, and the Louisiana Agriculture Teachers’ Association. Professional development organizers should also consider years of teaching experience when planning professional development seminars.

In spring 2018, nine agriculture students from Louisiana State University traveled to Nicaragua for a study abroad course. During this experience, students explored agricultural industries and engaged in cultural tours as well as in a service-learning project. Evidence has demonstrated that such experiences can transform students’ intercultural sensitivity, global knowledge, and views on agriculture. To facilitate such an experience, however, requires educators to design experiences that challenge students’ existing values and worldviews – a concept known as dissonance. Mezirow theorized that when individuals reflect critically on dissonance, it spurs a transformational learning (TL) process. However, knowledge of the types of dissonance that initiate TL in study abroad programs is insufficient. This study, therefore, sought to understand the multiple ways that students experienced dissonance during a study abroad course. Through our analysis, four forms of dissonance emerged: (1) environmental, (2) sociocultural, (3) intellectual, and (4) personal. When viewed through the lens of TL theory, the forms of dissonance appeared to shape and influence how students experienced TL as well as their resulting perspective changes. As a consequence, this study provided important insights into how study abroad courses could be designed and delivered to better encourage the maturation of students’ perspectives on global issues and problems.
Assessing School-based Agricultural Education Teacher Familiarity, Knowledge, and Perceptions of Supervised Agricultural Experience Categories

Changes in Supervised Agricultural Experiences (SAEs) and a lack of SAE category knowledge have been identified as causes to declining SAE participation (Dyer & Osborne, 1995; Steel, 1997; Wilson & Moore, 2007). Recently, the National Council for Agricultural Education and the National FFA Organization have redefined SAE and created new categories for SAEs in an attempt to be more inclusive of agricultural projects and to increase participation. This descriptive study assessed (n=116) school-based agricultural education (SBAE) teachers’ knowledge in categorizing SAE scenarios into previous and new SAE categories. Teacher familiarity with old and new categories was determined as well as teacher practices and opinions on new categories. Results indicated teachers were more familiar with old SAE categories than new categories. SBAE teachers consistently scored lower on their ability to classify SAE scenarios with new SAE categories compared to old categories. Teachers thought new categories were more difficult to teach students and most teachers had not taught their students information on new categories. This led to the recommendation for streamlined communication between decision-making groups in the agricultural education community and SBAE teachers in the field. Various forms of professional development are needed for teachers in the area of SAE categorization.
Atmospheric ammonia retrieval from the TANSO-FTS/GOSAT thermal infrared sounder

Abstract. Hyperspectral thermal infrared sounders enable us to grasp the global
behavior of minor atmospheric constituents. Ammonia, which imparts large
impacts on the atmospheric environment by reacting with other species, is one
of them. In this work, we present an ammonia retrieval system that we
developed for the Greenhouse Gases Observing Satellite (GOSAT) and the
estimates of global atmospheric ammonia column amounts that we derived from
2009 to 2014. The horizontal distributions of the seasonal ammonia column
amounts represent significantly high values stemming from six anthropogenic
emission source areas and four biomass burning ones. The monthly mean time
series of these sites were investigated, and their seasonality was clearly
revealed. A comparison with the Infrared Atmospheric Sounding Interferometer
(IASI) ammonia product showed good agreement spatially and seasonally, though
there are some differences in detail. The values from GOSAT tend to be
slightly larger than those from IASI for low concentrations, especially in
spring and summer. On the other hand, they are lower for particularly high
concentrations during summer, such as eastern China and northern India. In
addition, the largest differences were observed in central Africa. These
differences seem to stem from the temporal gaps in observations and the
fundamental differences in the retrieval systems.

Published: January 2020

Abstract. This is the initial paper in a pair of articles devoted to
silicate minerals from fumaroles of the Tolbachik volcano (Kamchatka,
Russia). These papers contain the first systematic data on silicate
mineralization of fumarolic genesis. In this article nesosilicates
(forsterite, andradite and titanite), cyclosilicate (a Cu,Zn-rich analogue
of roedderite), inosilicates (enstatite, clinoenstatite, diopside, aegirine, aegirine-augite, esseneite, “Cu,Mg-pyroxene”, wollastonite,
potassic-fluoro-magnesio-arfvedsonite, potassic-fluoro-richterite and
litidionite) and phyllosilicates (fluorophlogopite, yanzhuminite,
“fluoreastonite” and the Sn analogue of dalyite) are characterized with a
focus on chemistry, crystal-chemical features and occurrence. Unusual
As5+-rich varieties of forsterite, andradite, titanite, pyroxenes,
amphiboles and mica are described. General data on silicate-bearing active
fumaroles and the diversity and distribution of silicates in fumarole
deposits are reported. Evidence for the fumarolic origin of silicate
mineralization is discussed.
Unusual silicate mineralization in fumarolic sublimates of the Tolbachik volcano, Kamchatka, Russia – Part 2: Tectosilicates

Published: January 2020

Abstract. This second of two companion articles devoted to silicate
mineralization in fumaroles of the Tolbachik volcano (Kamchatka, Russia)
reports data on chemistry, crystal chemistry and occurrence of
tectosilicates: sanidine, anorthoclase, ferrisanidine, albite, anorthite,
barium feldspar, leucite, nepheline, kalsilite, sodalite and hauyne.
Chemical and genetic features of fumarolic silicates are also summarized and
discussed. These minerals are typically enriched with “ore” elements (As,
Cu, Zn, Sn, Mo, W). Significant admixture of As5+ (up to 36 wt % As2O5 in sanidine) substituting Si is the most characteristic. Hauyne contains up to 4.2 wt % MoO3 and up to 1.7 wt % WO3. All studied silicates are hydrogen-free, including mica and
amphiboles which are F-rich. Iron-bearing minerals contain only Fe3+
due to strongly oxidizing formation conditions. In Tolbachik fumaroles,
silicates were formed in the temperature range 500–800 ∘C as a result
of direct deposition from the gas phase (as volcanic sublimates) or
gas–rock interactions. The zonation in distribution of major silicate
minerals observed in a vertical section of the Arsenatnaya fumarole, from
deep (the hottest) to upper parts is diopside + forsterite + enstatite
+ andradite → diopside → fluorophlogopite + diopside → sanidine + fluorophlogopite → sanidine. This is in agreement with
volatilities of major species-defining metals in volcanic gases. From a
crystal-chemical viewpoint, this series corresponds to the following
sequence of crystallization of minerals with temperature decrease:
nesosilicates → inosilicates → phyllosilicates → tectosilicates.
