The CROPS Curriculum Experiment: Evaluating the Farm Safety Knowledge Gained Among Secondary Appalachia Youth
Authors: Schafbuch Morgan L. , Vincent Stacy K. , Mazur Joan , Watson Jennifer , Westneat Susan
Published: January 2018

Rural youth in poverty stricken Appalachian communities are the highest at-risk population for tractor rollover accidents (Cole, 2007). The Apprenticeship of Observation theory (Lortie, 1975) concludes that the “apprentice” learns from watching those perceived to be the teacher and their work and so mimic their actions. Thus, farm youth who often overlook safety precautions believe farm accidents are simply a way of life. This project was partially funded through the Southeast Center for Agricultural Health and Injury Prevention. The funds assisted in the development of a Cost-effective Rollover Protective Structure (CROPS) curriculum. A total of 54 (N = 54) secondary agriculture mechanics students, served as the treatment group (n = 31) and control group (n = 23). The treatment group received farm safety instruction from their secondary agriculture teacher through the use of the CROPS curriculum while the control group received their farm safety instruction from their secondary agriculture teacher who taught, only, to reach the required state standards. Results from the quasi-experimental design study revealed a statistically significant gain in farm safety practices from the treatment group as compared to the control group. Recommendations to the participants, future participants, and research are also included.
Variability Versus Continuity: Student Teachers’ Perceptions of Two University Supervision Formats
Authors: Shoulders Catherine W. , Edgar Don , Bolton Andrew
Published: January 2018

The aspects that make up the student teaching experience, from site placement to feedback received from site and university supervisors, are each influential on the quality of the student teaching experience. Whether made consciously or unconsciously, university supervisors must decide whether to allocate observations by student, wherein each supervisor meets with a small set of student teachers multiple times, or by visit, wherein each supervisor meets with every student teacher one time. This qualitative study explored student teachers’ perceptions after being observed using one of the two aforementioned formats. Student teachers valued time with their university supervisors, reporting a desire for more time under observation and for discussion and feedback. They also appreciated the variability in feedback supplied by multiple supervisors, but desired continuity in feedback found with a single supervisor. Recommendations, including several potential observation formats, are offered to assist university supervisors in maximizing their time with student teachers while meeting the student teachers’ conflicting needs of both variability and continuity in feedback.
An Observational Analysis of Coaching Behaviors for Career Development Event Teams: A Mixed Methods Study
Authors: Ball Anna , Bowling Amanda , Sharpless Justin D.
Published: January 2018

School Based Agricultural Education (SBAE) teachers can use coaching behaviors, along with their agricultural content knowledge to help their Career Development Event (CDE) teams succeed. This mixed methods, collective case study observed three SBAE teachers preparing multiple CDEs throughout the CDE season. The teachers observed had a previous track record of success at the state level with multiple CDE teams. The teachers were observed twice on location during CDE practices and their behaviors were documented using an observational instrument. Following the observations, interviews were conducted with all teachers using the quantitative data to guide the interview questions. Both sets of data were analyzed together and it was concluded that practice mechanics, content knowledge, and coach and team were key components to preparing CDE teams. Separately, the qualitative interviews found the use of goal setting, as major component of CDE team preparation. From the findings it is recommended that CDE coaches use strategies that align with practice mechanics, content knowledge, coach and team, and goal setting when preparing CDE teams.
Expectation Congruency and Psychosocial Support in Formal Agriculture Teacher Mentoring Relationships
Authors: Tummons John , Kitchel Tracy , Garton Bryan L.
Published: January 2018

Educational leaders have widely implemented mentoring and induction programs to support beginning teachers as they enter the profession. A variety of contextual factors within the mentoring dyad and program may impact the mentoring relationship and subsequent support received by the beginning teacher. The purpose of this study was to describe the relationship among mentoring Expectation Congruency, Interaction, and Psychosocial Support received by agriculture teachers participating in Beginning Teacher Mentor/Induction program. Researchers collected mentoring relationship data from 83 first and second year agriculture teachers participating in a statemandated mentoring and induction program, with a 95.35% response rate. We used a hierarchical multivariate linear regression to determine the proportion of unique variance in Psychosocial Support attributable to differences in Expectation Congruency, Interaction time, and covariates identified through a review of literature. Researchers concluded differences in Expectation Congruency and Perceived Similarity each explained a large (d >1.0) proportion of variance in Support received by beginning teachers in the Acceptance, Counseling, Friendship, and Role Model functions. Variation in interaction time did not explain significant proportions of variance in support received for any psychosocial support constructs.
Student Teaching Changed Me: A Look at Kolb's Learning Style Inventory Scores Before and After the Student Teaching Experience
Authors: Smith Kasee L. , Rayfield John
Published: January 2018

Student teaching as the culminating experience of a teacher preparation program has been shown to be of great importance in the preparation of pre-service agricultural educators (Harlin, Roberts, Mowen, Edgar, & Briers, 2007; Roberts, Mowen, Edgar, Harlin, & Briers, 2007; Kitchel & Torres, 2006, 2007; Myers & Dyer, 2004). Kolb’s Learning Style Inventory (KLSI) is an instrument designed to examine individual preference for learning in four learning modes: active experimentation (AE), reflective observation (RO), concrete experience (CE), and abstract conceptualization (AC). In addition, the KLSI examines learning preferences in the dimensions of grasping and transforming experience. This descriptive study examined the KLSI scores for two semesters of student teachers (N = 37) from Texas A&M University at both the beginning and end of their student teaching experience. Student teachers were observed as falling into all nine learning styles as indicated by Kolb and Kolb (2013) at both the beginning and end of the student teaching experience. Results indicated that there was wide range of changes in individual student teachers. Active experimentation was the learning mode showing the greatest amount of change among the population, and changes in the group were more apparent in the dimension of transforming experience than in grasping experience.
A Multidimensional Needs Assessment of Social Emotional Learning Skill Areas
Authors: Yopp Ashley M. , McKim Billy R. , Moore Lori L. , Odom Summer F. , Hanagriff Roger
Published: January 2018

Social and Emotional Learning (SEL) has often been an umbrella term for a wide range of competencies, including emotional processes, social and interpersonal skills, and cognitive regulation (Jones, Bouffard, & Weissbourd, 2013). We used the Borich (1980) needs assessment model to assess the professional development needs of Texas agricultural education teachers in core SEL skill areas. Data were collected with three forms of a paper questionnaire to determine teachers’ self-perceived levels of competence in core SEL skill areas. Twenty SEL indicators were assessed in four ways (Importance, Ability to Perform, Knowledge, and Ability to Teach), and then used to create three latent variables (Performance Competence, Knowledge Competence, and Consequence Competence), which served as dimensions of professional development needs. Agriculture teachers perceived the importance of all core SEL skill areas as having average or greater importance, their ability to model core SEL skill areas as average or greater, their knowledge of core SEL areas as average or greater, and possessing average or greater ability to teach core SEL skill areas. The findings of this study support the Collaborative for Academic, Social, and Emotional Learning (CASEL, 2003) report and emphasize the importance of SEL in agricultural education.
Teaching with Animals: The Role of Animal Ambassadors in Improving Presenter Communication Skills
Authors: Fuhrman Nicholas E. , Rubenstein Eric D.
Published: January 2018

Much is known about the benefits of interacting with animals for learners. However, little is known about the animals’ potential influence on the communication ability of the presenter/educator. The purpose of this qualitative study was to describe the experience of undergraduate students who used live animals (baby chicks, turtles, salamanders, and non-venomous snakes) during in-class and outreach presentations and the animals’ role in influencing their communication ability. The influence of an instructor who teaches with such animals was also examined. A purposive sample of students enrolled in an introductory environmental education course open to all majors was obtained and five students agreed to participate in semi-structured interviews. Once audio was recorded and transcribed, the constant comparative method was used to analyze the data. Six reoccurring themes emerged. Presenting with a live animal (1) helped students feel less nervous while teaching, (2) increased presenter confidence, (3) promoted flexibility while teaching, (4) encouraged audience analysis, (5) helped create a positive, comfortable learning environment, and (6) influenced student career decisions. These themes aligned with Bandura’s triatic reciprocality model. Pre-service teacher education programs may consider using small, live animals, when relevant, with apprentice teachers as they can equally benefit the presenter and learning environment.
Characteristics of Enthusiastic and Growing School-Based Agricultural Education Teachers: A Delphi Approach
Authors: Easterly III R.G. (Tre) , Myers Brian E.
Published: January 2018

The most optimal way to prepare teachers is a source of debate and inquiry. The common view held in school-based agricultural education is to use professional development to augment what teachers learned in their teacher preparation program. This has been typically implemented through induction support and generic professional development. Fessler and Christensen (1992) described a teacher career cycle that highlights the need to differentiate professional development for teachers beyond the induction stage. Teachers in the Enthusiastic and Growing stage are described as having a high level of competence, but continue to grow as professionals. The purpose of this study was to determine the characteristics of Enthusiastic and Growing school-based agriculture education teachers in order to inform professional development practice. A panel of 105 Enthusiastic and Growing teachers were selected to serve on a Delphi panel and asked to identify the characteristics of an expert agriculture teacher. Twenty-seven responses were agreed upon by the panel. Some characteristics were congruent with the existing descriptions of Enthusiastic and Growing teachers, while some descriptions were unique to school-based agricultural education. Based on these findings, professional development should be implemented using a systems approach to promote these characteristics in teachers.
The Mentoring Experience: Leadership Development Program Perspectives
Authors: Lamm Kevan W. , Sapp Rochelle , Lamm Alexa J.
Published: January 2018

Using a semi-structured interview approach, ten mentors from a leadership development program focused on building leaders in Colleges of Agriculture and Life Sciences across the nation provided insights regarding their mentoring method, process, and experiences. Mentors interviewed agreed the mentoring process was beneficial for themselves as well as their mentee. However, clear thematic differences were evident depending on whether a previously existing relationship was in place between mentor and mentee. Specifically, mentoring relationships that were extensions of previous relationships tended to have less formal structures and more subjective outcomes than newly established mentoring relationship counterparts. Nevertheless, both categories of mentoring relationships indicated a desire for a formal set of mentoring expectations as well as access to program curriculum to help guide and inform the process.
An Exploration of How Attire Shapes High School Students' Perceptions of Agriculture Teachers
Authors: Shoulders Catherine W. , Sellick Sable A. , Southward Leigh , Blythe Jessica M.
Published: January 2018

An individual’s attire sends messages to those who view them (Damhorst, 1990), and the clothing choices made by teachers may influence students’ perceptions of the school (Workman & Freeburg, 2010). A majority of teacher dress codes require formal clothing (Workman & Freeburg, 2010); however, agricultural education teachers often work in educational environments which are more work-oriented than the traditional classroom (Shoulders & Myers, 2012). This qualitative study explored students’ perceptions of agriculture teachers based on their attire. Participants were shown an image of a teacher in attire ranging from casual to formal and asked questions about the teacher’s knowledge, discipline, respect, and ability to relate to students. Participants’ perceptions were similar regarding the formally and informally dressed general education teacher, but differed based on their involvement with the school’s agriculture program when viewing formally and informally dressed agriculture teachers. These findings suggest that while agriculture teachers’ attire may influence students’ perceptions of the teacher, the manner in which the attire shapes those perceptions may differ based on students’ experiences in agricultural education.
Undergraduate Knowledge Legitimation Strategies: Metacognition and Epistemological Development
Authors: Gordon Jessica E. , Ball Anna L.
Published: January 2018

Undergraduate epistemology typically transitions from an absolute perspective with a reliance on external knowledge authority to a more open epistemology that utilizes metacognition to evaluate knowledge claims. In the undergraduate agricultural classroom, student epistemic development, combined with deeply embedded agricultural beliefs and values, can lead to rigid perspectives that may inhibit effective communication and collaboration between diverse students, and thwart epistemic development necessary for students to entertain and synthesize widely divergent knowledge claims. This research sought to explore the characteristics and sources of knowledge undergraduates considered legitimate, and the internal processes undergraduate agricultural students used to assess the legitimacy of knowledge claims. Findings from this qualitative, multiple case study revealed students utilized specific metacognitive processes to assess the validity of conflicting agricultural knowledge claims. In addition, findings indicated students implemented specific legitimation criteria when assessing professors as credible sources of agricultural knowledge. These findings suggest educators should recognize and validate students’ prior experience, social affiliations, and implement pedagogies that facilitate student learning through dialogue involving students holding diverse agricultural perspectives.
Building Extension Partnerships with Government to Further Water Conservation Efforts
Authors: McKee Brandon , Huang Pei-wen , Lamm Alexa J.
Published: January 2018

Extension, being a local, state and federally funded program has a natural partnership with government agencies at all three levels, however these partnerships could be built upon and targeted at specific audiences for greater effect if more is known about how government influences public perception. The government has recognized the need for increased public engagement in water conservation to ensure the sustainability of water resources for future generations and taken action through incentive programs and regulations. Political affiliation is known to influence public perception of government initiatives, which may impact levels of intention and engagement in water conservation. This study explored how US residents responded to positive and negative governmental influences on water conservation practices using an online survey. The findings revealed significant differences in the water conservation activities respondents are currently engaged in, as well as future intentions, depend upon political affiliation. Additionally, intention can be predicted by political affiliation and positive government perceptions. By examining the dissonance created by respondents’ engagement and intention to take water conservation action, guidance can be provided to extension educators on how to collaborate with government agencies to develop and implement programs and policies that encourage or enforce engagement in water conservation behaviors.
Large particulate nitrate formation from N2O5 uptake in a chemically reactive layer aloft during winter time in Beijing

Published: January 2018

Abstract. Particulate nitrate (pNO3−) is a dominant component of secondary aerosols in urban areas. Therefore, it is critical to explore its formation mechanism to assist with the planning of haze abatement strategies. Simultaneous ground-based and tower-based measurements were conducted during a winter heavy haze episode in urban Beijing, China. We found pNO3− formation via N2O5 heterogeneous uptake was negligible at ground level, due to the presence of high NO concentrations limiting the production of N2O5. In contrast, the contribution from N2O5 uptake was larger at higher altitudes (e.g., > 150 m), which was supported by the observed large total oxidant (NO2 + O3) missing aloft compared with ground level. The nighttime integrated production potential of pNO3− for the higher altitude air mass overhead urban Beijing was estimated to be 50 μg m−3, and enhanced the surface pNO3− significantly with 28 μg m−3 after nocturnal boundary layer broken in the next morning. In this case, the oxidation of NOX to nitrate was maximized once N2O5 uptake coefficient over 0.0017, since N2O5 uptake dominated the fate of NO3 and N2O5 with the presence of large aerosol surface concentrations. These results highlight that pNO3− formation via N2O5 heterogeneous hydrolysis at higher altitude air masses aloft could be an important source for haze formation in the urban airshed during winter time. Accurately describing the formation and development of reactive air masses aloft is a critical task for improving current chemical transport models.
Improved slant column density retrieval of nitrogen dioxide and formaldehyde for OMI and GOME-2A from QA4ECV: intercomparison, uncertainty characterization, and trends

Abstract. Nitrogen dioxide (NO2) and formaldehyde (HCHO) column data from satellite instruments are used for air quality and climate studies. Both NO2 and HCHO have been identified as precursors to the ozone and aerosol Essential Climate Variables, and it is essential to quantify and characterize their uncertainties. Here we present an intercomparison of NO2 and HCHO slant column density (SCD) retrievals from 4 different research groups (BIRA-IASB, IUP, and KNMI as part of the Quality Assurance for Essential Climate Variables (QA4ECV) project consortium, and NASA) and from the OMI and GOME-2A instruments. Our evaluation is motivated by recent improvements in Differential Optical Absorption Spectroscopy (DOAS) fitting techniques, and by the desire to provide a fully traceable uncertainty budget for climate data record generated within QA4ECV. The improved NO2 and HCHO SCD values are in close agreement, but with substantial differences in the reported uncertainties between groups and instruments. As a check of the DOAS uncertainties, we use an independent estimate based on the spatial variability of the SCDs within a remote region. For NO2, we find the smallest uncertainties from the new QA4ECV retrieval (0.8 × 1015 molec. cm−2 for both instruments over their mission lifetimes). Relative to earlier approaches, the QA4ECV NO2 retrieval shows better agreement between DOAS and statistical uncertainty estimates, suggesting that the improved QA4ECV NO2 retrieval has reduced but not altogether eliminated systematic errors in the fitting approach. For HCHO, we reach similar conclusions (QA4ECV uncertainties of 8–12 × 1015 molec. cm−2 ), but the closure between the DOAS and statistical uncertainty estimates suggests that HCHO uncertainties are indeed dominated by random noise from the satellite’s level-1 data. We find that SCD uncertainties are smallest for high top-of-atmosphere reflectance levels. From 2005 to 2015, OMI NO2 SCD uncertainties increase by 1–2 %/yr related to detector degradation and stripes, but OMI HCHO SCD uncertainties are remarkably stable (increase
Patterns of longer-term climate change effects on CO2 efflux from biocrusted soils differ from those observed in the short-term

Published: January 2018

Abstract. Biological soil crusts (biocrusts) are predicted to be sensitive to the increased temperature and altered precipitation associated with climate change. We assessed the effects of these factors on soil carbon dioxide (CO2) balance in biocrusted soils using a sequence of manipulations over a nine-year period. We warmed biocrusted soils by 2 and, later, by 4 °C to better capture updated forecasts of future temperature, as well as altered monsoon-season precipitation at a site on the Colorado Plateau, USA. Within treatment plots, we used 20 automated flux chambers to monitor net soil exchange (NSE) of CO2 hourly, first in 2006–2007 and then again in 2013–2014, for a total of 39 months. Net CO2 efflux from biocrusted soils in the warming treatment increased a year after the experiment began (2006–2007). However, after 9 years and even greater warming (4 °C), results were more mixed, with a reversal of the increase in 2013 (i.e., controls showed higher net CO2 efflux than treatment plots) and with similarly high rates in all treatments during 2014, a wet year. Over the longer-term, we saw evidence of reduced photosynthetic capacity of the biocrusts in response to both the temperature and altered precipitation treatments. Patterns in biocrusted soil CO2 exchange under experimentally altered climate suggest that (1) warming effects were diminished later in the experiment, even in the face of larger warming and (2) likely drivers of the treatment effects were changes in biocrust species composition and changes in root respiration due to vascular plant responses.
Self-anointing behaviour in captive titi monkeys (Callicebus spp.)

Published: January 2018

Abstract. Self-anointing behaviour using Bauhinia sp. was reported in
two captive titi monkeys (Callicebus coimbrai and
Callicebus barbarabrownae). The study was carried out from
October 2013 to May 2014 during an experimental study investigating
the gut passage time of these individuals at the Getúlio Vargas
Zoobotanical Park, north-eastern Brazil. Although leaves, petioles
and flowers of Bauhinia contain chemical substances that
could affect the presence of ectoparasites, it is unclear if titi
monkeys demonstrate self-anointing behaviour as a method of
self-medication. However, due to the presence of large glands in
C. coimbrai and C. barbarabrownae chests, and the
high frequency of occurrence observed for the adult male, we
cautiously suggest that the use of Bauhinia may be linked
to olfactory communication.
Warm Winter, Thin Ice?
Authors: Stroeve Julienne , Schroder David , Tsamados Michel , Feltham Daniel
Published: January 2018

Abstract. Winter 2016/2017 saw record warmth over the Arctic Ocean, leading to the least amount of freezing degree days north of 70° N since at least 1979. The impact of this warmth was evaluated using model simulations from the Los Alamos sea-ice model (CICE) and CryoSat-2 thickness estimates from three different data providers. While CICE simulations show a broad region of anomalously thin ice in April 2017 relative to the 2011–2017 mean, analysis of three CryoSat-2 products show more limited regions with thin ice and do not always agree with each other, both in magnitude and direction of thickness anomalies. CICE is further used to diagnose feedback processes driving the observed anomalies, showing 11–13 cm reduced thermodynamic ice growth over the Arctic domain used in this study compared to the 2011–2017 mean, and dynamical contributions of +1 to +4 cm. Finally, CICE model simulations from 1985–2017 indicate the negative feedback relationship between ice growth and winter air temperatures may be starting to weaken, showing decreased winter ice growth since 2012 as winter air temperatures have increased and the freeze-up has been further delayed.
The Political Philosophy of Impersonation: A Libertarian Analysis
Authors: Loo Andy , Block Walter
Published: January 2018

Impersonation is a criminal act; it constitutes invasion and, in some cases, fraud. Although often associated with the term “identity theft,” impersonation is primarily a violation of the rights of the recipient of the communication, rather than that of the person being impersonated, whose rights are only sometimes violated. The present paper is devoted to defending this position. It attempts to overcome the objection that there is no violence necessarily connected to this act, or that the violence is directed toward the person being impersonated instead of the recipient of the impersonating message.

Theoretical Profiles for the Evaluation of Insider Trading in a Functional Model of Financial Instruments Market
Authors: Fandella Paola
Published: January 2018

The analysis is based on the premise that the capital market is characterized by weak forms of risk management, to be intended, in this case, as risk of information asymmetry as well as operational inefficiency, as there are no hedging schemes to prevent external actions and internal mechanisms are not inspired by adequate transparency principles.After a critical review of the theoretical effects of insider trading, starting with a market equilibrium assessment, this analysis seeks to demonstrate the absence of any positive effect linked to insider trading in relation to any type of variable and for any model of the securities market.Starting from the assumption that the negative trading activity of insiders manifests in any securities market structure, it has been shown that an operating model characterized by the presence of professional operators appears to be more capable of opposing a significant barrier to the entry of insiders.On the other hand, it has also been shown that the presence of professional operators cannot act alone and it may also lose action incisiveness and even cause informative viscosity effect, when such professional or institutional operators are directly involved in privatization operations.

La pertinencia de enseñar a aprender estratégicamente en el nivel de posgrado = The pertinence of teaching to learn strategically in postgraduate education
Authors: Martín-Cuadrado Ana María , Salcedo Lobaton Elizabeth
Published: January 2018

Resumen: Aprender estratégicamente es hacerlo con plena conciencia de la influencia del entorno y de las capacidades propias para aprender. Este aprendizaje, asumido como paradigma orientador por algunas reformas de la educación básica y de pregrado, no suele ser una preocupación para los gestores educativos en la enseñanza de posgrado. Mediante el estudio de un caso, que abordó la consulta de alumnos, docentes, coordinadores y especialistas educativos de una maestría a distancia, se evidenciaron necesidades y carencias que llevan a plantear la pertinencia de enseñar a aprender estratégicamente en un programa de posgrado. La exploración del caso de estudio revela posturas de alumnos y docentes sobre la necesidad de fortalecer algunas capacidades estratégicas, muestra importantes brechas de capacidad, y plantea la discusión sobre la responsabilidad que tienen alumnos y docentes en el logro de las capacidades para aprender en un contexto de educación a distancia.Abstract: Strategic learning means to learn with full awareness of the influence of the environment and the skills within learning. This kind of learning, which is made into the guiding paradigm on some reforms of basic and college education, is often not a concern to those in charge of managing distance education. Through a case study, that involves consultation with the students, professors, coordinators and specialists of a distance master degree program, certain needs and gaps were shown, which lead us to raise the issue about the pertinence of teaching to learn strategically on a postgraduate program. The exploration of the case study reveals points of view from students and professors about the necessity of strengthen some strategic skills, demonstrates major capacity gaps and promotes the discussion about the accountability of students and professors in the achievement of the skills to learn, in a context of distance education.

Published: January 2018

Les espaces périurbains des grandes villes africaines font face aux mutations des systèmes agraires. Ils sont intégrés à l’économie de marché grâce à une production orientée vers la demande urbaine. La périphérie rurale de la métropole dakaroise est au coeur des dynamiques d’investissement par les agro-industries. L’article analyse les logiques d’implantation des entreprises agro-industrielles, les stratégies spatiales développées ainsi que leurs effets sur les communautés et l’environnement. L’analyse postule l’hypothèse de l’émergence d’un système de production agro-industriel porté par des acteurs de divers profils. Ces derniers s’inscrivent dans une logique capitaliste d’exploitation agricole, bouleversant l’organisation socioéconomique des populations locales ainsi que leurs rapports à l’espace. L’analyse s’appuie sur des données qualitatives recueillies en 2015 et 2017 auprès des entreprises agro-industriels et des populations de la zone. Les agro-industries, de profils variés, développent des stratégies territoriales inscrites dans une dynamique de production mondiale plus ou moins intégrée à la demande locale métropolitaine.
Musiciens de rue et renouveau des espaces publics à Paris

Published: January 2018

Alors qu’ils avaient quasiment disparu des grandes villes occidentales, les musiciens de rue font aujourd’hui de nouveau partie du paysage de ces villes. Notre hypothèse centrale est que ce renouveau, non seulement, reflète un changement en cours dans les usages, dans les modes de régulation et dans les conceptions de l’espace public, mais contribue en retour à renforcer le caractère public des espaces où il se déploie. En nous appuyant sur deux enquêtes menées à Paris, nous nous intéressons d’abord aux logiques spatiales de l’activité musicienne informelle et à la manière dont les musiciens tirent profit de l’hétérogénéité des espaces publics. Nous montrons ensuite comment les musiciens participent à la recomposition contemporaine de ces espaces, de manière éphémère en activant desspots, mais aussi, à plus long terme, en contribuant à l’émergence de microcentralités de divertissement qui se perpétuent dans le temps.
Le dialogue des imaginaires. Formes du monstrueux et merveilleux géographique dans Voyage au centre de la Terre (Jules Verne, 1867)

Published: January 2018

Parmi les 62 romans qui composent les Voyages extraordinaires de Jules Verne (1828-1905), Voyage au centre de la Terre (1867) est celui où l’auteur décline le plus grand nombre de figures, de formes du monstrueux. Or ces dernières constituent toutes une forme spécifique du merveilleux, opérateur qui permet dans le récit vernien le basculement vers un imaginaire géographique. Dans ce monde littéralement extraordinaire, la lente descente qui est effectuée par les héros constitue une des illustrations romanesques les plus efficaces d’un des principaux schèmes analysés par Gilbert Durand dans son ouvrage consacré aux Structures anthropologiques de l’imaginaire (1990).
Interpréter un contrat sans rechercher l’intention commune des parties ? Illustration à l’aide de l’assurance automobile
Authors: Caron Vincent
Published: January 2018

Contrairement à ce qui se produit dans la théorie classique, la recherche de l’intention commune des contractants ne guide pas le processus d’interprétation de la Convention d’indemnisation directe pour le règlement des sinistres automobiles ainsi que la police d’assurance automobile standard. Créatures particulières, ces actes juridiques sont plutôt interprétés à la lumière de la loi, de la jurisprudence et de la règle contra proferentem, ce qui laisse ainsi entrevoir que la détermination de l’intention commune est davantage une question de droit qu’une question de fait. L’étude de l’interprétation de ces deux actes juridiques pourrait bien jeter les bases d’une théorie interprétative du contrat non mutuel (réglementé, standardisé, légal ou imposé).
Accès à la justice pour protéger l’environnement au Québec : réflexions sur la capacité à agir des particuliers et des groupes environnementaux
Authors: Bélanger Michel , Halley Paule
Published: January 2018

Bien que les droits à l’environnement et de participation du public sont fréquemment proclamés et font l’objet d’un très large consensus, leur mise en oeuvre demeure bien souvent ardue. Le présent article fait un retour sur l’expérience québécoise eu égard à l’accès à la justice en matière d’environnement, afin de réfléchir au chemin parcouru par les particuliers et les associations de défense de l’environnement et les défis qui leur restent à relever.

Outre les avantages indéniables du recours particulier à l’injonction prévu depuis 1978 aux articles 19.1 à 19.7 de la Loi sur la qualité de l’environnement, les tribunaux ont, dans les litiges de nature environnementale, interprété largement les principes de base du Code de procédure civile relatifs à l’intérêt suffisant pour ester en justice.

Lorsque la nature des enjeux soulevés dans un litige environnemental ne permet pas aux tribunaux de conclure à l’existence d’un intérêt suffisant au sens de l’article 85(1) C.p.c., ils ont régulièrement reconnu cet intérêt aux demandeurs, tant individuellement que par le biais d’associations, en invoquant l’existence de questions de droit public au sens de 85(2) C.p.c. Il en va de même lorsque l’objet du litige porte sur le contrôle de la légalité d’une autorisation environnementale délivrée par le ministre de l’Environnement. En accueillant ces demandes, les tribunaux ont reconnu aux demandeurs le même intérêt pour demander une injonction ordonnant la cessation des activités concernées et ce, sans égard au fait que les demandeurs étaient des associations ou fréquentaient le lieu de l’infraction au sens de l’article 19.3 L.q.e.

Avec le temps, les tribunaux ont donc élargi de façon non négligeable l’accès à la justice des individus et des groupes en reconnaissant leur intérêt à agir dans l’intérêt public pour faire respecter leurs droits à l’environnement, de même qu’en démontrant leur ouverture à réduire certaines des charges financières associées aux recours judiciaires. Usant de leur pouvoir discrétionnaire, les tribunaux ont interprété le droit de manière à permettre aux particuliers et aux associations de participer de manière plus effective à la protection de l’environnement, notamment en se portant à sa défense, au nom de l’intérêt public et du droit de chacun à l’environnement, et à s’assurer d’être saisis de questions importantes, qui autrement échapperaient au forum judiciaire.
Desde la clínica de fertilidad: alianzas reproductivas, madres jubileas y bebés probeta / From the fertility clinic: reproductive alliances, jubilee mothers and test tube babies
Authors: Taranilla Raquel
Published: January 2018

Resumen: Este artículo comienza abordando el discurso producido en torno a la tecnología de la reproducción asistida. A partir de los textos emitidos por la clínica de fertilidad, se pretende comprender el papel actual de los tratamientos reproductivos y plantear, yendo más allá de las críticas que generan, en qué han ayudado a derribar estereotipos muy establecidos. En primer lugar, la generalización de las tecnologías de reproducción asistida ha acabado con el relato hegemónico sobre la concepción humana (en el que un espermatozoide poderoso logra conquistar un óvulo e iniciar una vida nueva). En segundo lugar, la clínica de fertilidad obliga a entender la reproducción humana como una tarea colectiva, en la que se generan relaciones fructíferas. En tercer lugar, también hace emerger nuevas subjetividades ligadas a la maternidad/paternidad y la filiación, que consiguen desestabilizar ciertas identidades de género y de familia que han sido privilegiadas hasta ahora. A modo de ejemplo de nueva subjetividad, se propone la maternidad jubilea, en cuya fusión de cuerpo y tecnología queda cuestionada con éxito la construcción social de la esterilidad.

Palabras clave: clínica de fertilidad, tecnología de reproducción asistida, maternidad, filiación, subjetividad, discurso de la medicina.

Abstract: This article addresses the discourse of assisted reproduction technology. By analyzing texts produced by fertility clinics, the aim is to describe the current role of reproductive treatments and to consider their benefits in undermining well-established stereotypes. First, the increase in the use of assisted reproductive technologies breaks down the hegemonic narrative of human conception (in which the powerful sperm conquers the egg to start a new life). Second, in fertility clinic human reproduction should be considered a collective task, in which fruitful relationships are developed. Third, assisted reproductive technology fosters the emergence of new subjectivities linked to motherhood/fatherhood and filiation, which destabilize prevailing gender and family identities. As an example of a new subjectivity, jubilee motherhood is proposed. The fusion of body and technology in it challenges the social construction of infertility.

Keywords: fertility clinic, assisted reproductive technology, motherhood, filiation, subjectivity, medical discourse.
Guardar el Secreto: la Invisibilización del Abuso Sexual Infantil / Keeping the Secret. Childhood Sexual Abuse and Mental Health
Authors: Erro Pérez Javier
Published: January 2018

Resumen: En este artículo se revisará la epidemiología del abuso sexual infantil, así como el impacto que tiene sobre la salud mental de la persona. Se analizarán mecanismos de invisibilización que permiten que, pese a que se dé en grandes porcentajes de la población y a que haya sido relacionado con problemas de salud mental, continúe sin producirse una respuesta proporcional a nivel social. Por último, se propondrán una serie de pautas acerca del papel que pueden jugar los profesionales de la salud mental en este campo.

Palabras clave: Abuso sexual infantil, salud mental, trauma, revisión crítica.

Abstract: In this article, the epidemiology of childhood sexual abuse and its impact on the mental health will be reviewed. Invisibilization mechanisms, which allow society for not giving a proportional response despite that child sexual abuse is happening in a big percentage of population and that it has been related to mental health problems, will be reviewed. Finally, reflections about mental health professionals role in this field will be discussed.

Keywords: Childhood sexual abuse, mental health, trauma, critical review.
Política de la supervivencia / Politics of Survival
Authors: Giorgi Gabriel
Published: January 2018

Resumen: Distintas intervenciones desde prácticas activistas y culturales en torno al VIH escenifican poéticas y políticas del resto corporal en las que se juegan, por un lado, una reorganización de los modos en que se dramatiza en umbral entre lo vivo y lo muerto en lo público –redefiniendo así el tejido mismo de lo que llamamos “comunidad”—; y por otro, indican los modos en que estos activismos impulsan una disputa sobre los “marcos de temporalización” desde los cuales lo viviente se vuelve reconocible políticamente y donde la noción de supervivencia adquiere una centralidad decisiva. Combinando materiales heterogéneos el artículo busca iluminar los modos en que los activismos y las culturas en torno al VIH configuran un terreno decisivo para pensar políticas de la supervivencia del presente.

Palabras clave: VIH, ACT-UP, Supervivencia, Temporalidades, Biopolítica.

Abstract: Different interventions from activist and cultural practices around HIV staged poetics and politics of the body remmant. They implie, on the one hand, a reorganitzation of the dramatization of the threshold between the living and the dead in the public space; and on the other, they indicate the ways in which these activisms mobilize a dispute over the “frames of temporalization” from which the living becomes politically recognizable and where the notion of survival acquires a decisive centrality. Combining heterogeneous materials, the article seeks to illuminate the ways in which activism and cultures on HIV constitute a decisive ground for thinking about the present policies of survival.

Keywords: IHV, ACT-UP, Survival, Biopolitics.
