Remote Sensing of Sustainable Rural-Urban Land Use in Mexico City: A Qualitative Analysis for Reliability and Validity
Authors: Rodríguez López Juan Miguel , Rosso Pablo , Scheffran Jürgen , Delgado Ramos Gian Carlo
Published: May 2017

Abstract | Mexico City is one of the largest cities on the globe and a site where important transformations of nature reserves into urban areas have been taking place. This paper compared the southern part of Mexico City based on free images available (Landsat – 30m) and high-resolution imagery (RapidEye – 5m) from an explorative qualitative perspective in the logic of reliability and validity. We argue that the resolution of the free imagery available for the assessment of urban development on the structural level of land use is not sufficient to identify the development of specific parts of the city. Despite the fact that the general pattern of changes in land use is observable, changes within the urban structure are difficult to see with a resolution of 30 meters per pixel in the Landsat images. For validity, this analysis is merely graphic, and it shows a promising matching of urban development with environmental and land complaints, nevertheless, a numerical analysis is needed in the future.
Leaders' sense of power and team performance: A moderated mediation model
Authors: Rong Yan , Yang Baiyin , Ma Lin
Published: May 2017

Organizational behavior researchers have typically focused on role- or structure-based power, such as hierarchical status and position in the social network. In contrast, we examined the psychological experience of power in organizations. Our purpose was to determine how and when a
team leader's subjective sense of power is beneficial in an organizational context. Data were collected from 70 work teams using a 2-wave design to test the proposed model. Results showed that a team leader's sense of power enhanced team performance by decreasing leader–member relationship
conflict, but only when perceived task interdependence was high. These associations remained after controlling for hierarchical status and demographic characteristics. Theoretical and practical implications are discussed.
Cooperation with friends or new encounters: Tie strength and shared leadership behaviors
Authors: Chen Na , Rau Pei-Luen Patrick
Published: May 2017

We combined the topics of shared leadership, which is a relatively new form of leadership adopted in virtual team management, and tie strength, which affects members' behaviors in online communities, to investigate how they are correlated in a social media context. We conducted 2 experiments
involving 64 participants; the first involved close friends and the second, new encounters. The 2 relationship contexts were compared to explore the effects of interpersonal relationships on shared leadership behaviors. Results indicated that in the high-tie-strength (close friend) context,
there was a positive correlation between tie strength and directive leadership, whereas in the low-tie-strength (new encounter) context, there was a positive correlation between tie strength and both positive feedback and social leadership. Thus, in the context of team management on social
media websites, we suggest that people adjust their leadership behavior according to the interpersonal relationships exhibited among team members.
Are more traditional employees less innovative? Colleagues' and leaders' influences matter
Authors: Xu Qin , Li Fangjun
Published: May 2017

We examined how the cultural value orientation of employees' traditionality influences their innovative behaviors in a group context. Our belief was that the behavioral influence of traditionality on individual innovation would be contingent upon group traditionality and transformational
leadership, as well as the combined moderating effect of these two variables. Participants were 282 employees and their 36 group leaders in a large telecommunication corporation in China. Results revealed that although traditionalists were superior to nontraditionalists in terms of individual
innovation, the latter group exhibited greater potential for innovative behaviors when their colleagues were less traditional and/or when they were led by a transformational leader. Moreover, traditionalists were found to be more innovative than nontraditionalists were when group traditionality
was high and transformational leadership was low. Research limitations and implications of the findings are discussed.

Effect of nano- and micro-alumina fillers on some properties of poly(methyl methacrylate) denture base composites
Authors: Kundie Fathie , Azhari Che , Ahmad Zainal
Published: May 2017

This research investigated the effects of alumina (Al2O3) micro- and nano-particles on poly(methyl methacrylate) (PMMA) denture base. Al2O3 was surface treated using (3-methacryloxypropyl)trimethoxysilane (?-MPS), added to methyl methacrylate (MMA), and mixed with PMMA powder. The filler volume fractions in the micro-composites were 0.5, 1, 2, 5 and 7 wt. %, whereas those in the nano-composites were 0.13, 0.25, 0.5, 1, 2 and 5 wt. %. The treated fillers were examined using Fourier transform infrared spectroscopy (FTIR). The influence of filler size and loading on mechanical properties was studied using fracture toughness and flexural tests. The thermal stability of the PMMA/Al2O3 composites was investigated using thermogravimetric analysis (TGA). In addition, the water absorption and solubility characteristic of the prepared composites was also investigated. The FTIR spectra showed new absorption bands, indicating the occurrence of surface modifications. Both micro- and nanoscale particles showed increased fracture toughness. The maximum value of 2.02 MPa?m1/2 was achieved with the addition of 0.5 wt. % nano-Al2O3, which accounts for a 39 % increase. In contrast to the flexural strength, the flexural modulus improved with increasing filler content. The micro-composites showed higher thermal stability than nano-composites. The water absorption and solubility of the prepared composites were slightly higher than those of the control. The use of low concentrations of Al2O3 nanoparticles may be of considerable interest in future studies to improve the mechanical properties of PMMA denture base.

Authors: Roglic-Korica Verica , Milonjic Slobodan
Published: May 2017

Scientific outputs of six countries (republics of the former Yugoslavia ? the Socialist Federal Republic of Yugoslavia): Serbia, Croatia, Slovenia, Bosnia and Herzegovina, Former Yugoslav Republic of Macedonia and Montenegro were discussed in this paper. For the purpose of comparison, the data for seven neighbouring countries of the former Yugoslavia (Albania, Greece, Bulgaria, Romania, Hungary, Austria and Italy) were given as well. Also, the data for the Group of Eight (G8) countries (the United States, Canada, the United Kingdom, France, Italy, Germany, Japan and the Russian Federation) and some European countries similar in population to ex-Yugoslav republics were included. To gain a more complete picture on the outputs in scientific production (e.g., publications and patents), data on several developed European countries, as well as the countries from other continents were given. The analysis, which included 33 countries, was made based on different bibliometric indicators for the period of five years (2008?2012). The data were collected from international databases.
Serum B cell activating factor and interleukin 10 levels in common variable immunodeficiency: Relationship with clinical findings
Authors: Mijanovic Radovan , Andrejevic Sladjana , Jurisic Vladimir , Bonaci-Nikolic Branka
Published: May 2017

Background/Aim. Common variable immunodeficiency (CVID) is an immunologically and clinically heterogeneous disorder. Disturbed cytokine production is implicated in dysfunctional immune response. The aim of this study was to investigated B-cell activating factor (BAFF) and interleukin (IL)- 10 levels in CVID patients. Methods. The study included 28 CVID patients diagnosed and followed during a 20-year period (mean follow-up 14.5 years). Control groups consisted of 4 patients with X-linked agammaglobulinemia (XLA) and 21 healthy subjects. According to clinical characteristics, the CVID patients were divided into four groups which partly overlap: chronic pulmonary diseases (n = 21), splenomegaly (n = 13), autoimmune diseases (n = 9) and patients with recurrent infections despite regular intravenous immunoglobulin (IVIg) substitution (n = 4). The serum levels of BAFF and IL-10 were measured by commercial ELISA. Results. The BAFF levels were found to be higher in all CVID patients compared to the healthy controls (p < 0.01). The most significant differences were observed in the patients with pulmonary diseases and splenomegaly (p < 0.0001). Also, concentrations of IL-10 were higher in all CVID patients in comparison with the XLA patients (p < 0.05) and healthy subjects (p < 0.01). A statistically significant positive correlation (r = 0.86; p < 0.01) was found between the levels of BAFF and IL-10 in the CVID patients with autoimmune diseases. We demonstrated that the CVID patients with chronic pulmonary diseases had higher levels of IL-10, while the CVID patients with recurrent infections had higher BAFF concentrations in comparison to the patients without these features (p < 0.05). Conclusion. In spite of the limited number of patients, this is the first report from Serbia, examining the serum levels of BAFF and IL-10 in the CVID patients. Our study showed significantly increased concentrations of serum BAFF and IL-10 in the patients with CVID compared to the healthy subjects. Further studies are needed to confirm our findings that the BAFF levels are more pronounced in patients with recurrent infections while IL-10 levels are higher in patients with chronic pulmonary diseases.

OBJECTIVE To characterize aminoaciduria and plasma amino acid concentrations in dogs with hepatocutaneous syndrome (HCS).

ANIMALS 20 client-owned dogs of various breeds and ages.

PROCEDURES HCS was definitively diagnosed on the basis of liver biopsy specimens (n = 12), gross and histologic appearance of skin lesions (4), and examination of skin and liver biopsy specimens (2) and presumptively diagnosed on the basis of cutaneous lesions with compatible clinicopathologic and hepatic ultrasonographic (honeycomb or Swiss cheese pattern) findings (2). Amino acid concentrations in heparinized plasma and urine (samples obtained within 8 hours of each other) were measured by use of ion exchange chromatography. Urine creatinine concentration was used to normalize urine amino acid concentrations. Plasma amino acid values were compared relative to mean reference values; urine-corrected amino acid values were compared relative to maximal reference values.

RESULTS All dogs had generalized hypoaminoacidemia, with numerous amino acid concentrations < 50% of mean reference values. The most consistent and severe abnormalities involved glutamine, proline, cysteine, and hydroxyproline, and all dogs had marked lysinuria. Urine amino acids exceeding maximum reference values (value > 1.0) included lysine, 1-methylhistidine, and proline.

CONCLUSIONS AND CLINICAL RELEVANCE Hypoaminoacidemia in dogs with HCS prominently involved amino acids associated with the urea cycle and synthesis of glutathione and collagen. Marked lysinuria and prolinuria implicated dysfunction of specific amino acid transporters and wasting of amino acids essential for collagen synthesis. These findings may provide a means for tailoring nutritional support and for facilitating HCS diagnosis.

OBJECTIVE To assess the immunogenicity of thermostable live-attenuated rabies virus (RABV) preserved by vaporization (PBV) and delivered to the duodenal mucosa of a wildlife species targeted for an oral vaccination program.

ANIMALS 8 gray foxes (Urocyon cinereoargenteus).

PROCEDURES Endoscopy was used to place RABV PBV (n = 3 foxes), alginate-encapsulated RABV PBV (3 foxes), or nonpreserved RABV (2 foxes) vaccine into the duodenum of foxes. Blood samples were collected weekly to monitor the immune response. Saliva samples were collected weekly and tested for virus shedding by use of a conventional reverse-transcriptase PCR assay. Foxes were euthanized 28 days after vaccine administration, and relevant tissues were collected and tested for presence of RABV.

RESULTS 2 of 3 foxes that received RABV PBV and 1 of 2 foxes that received nonpreserved RABV seroconverted by day 28. None of the 3 foxes receiving alginate-encapsulated RABV PBV seroconverted. No RABV RNA was detected in saliva at any of the time points, and RABV antigen or RNA was not detected in any of the tissues obtained on day 28. None of the foxes displayed any clinical signs of rabies.

CONCLUSIONS AND CLINICAL RELEVANCE Results for this study indicated that a live-attenuated RABV vaccine delivered to the duodenal mucosa can induce an immune response in gray foxes. A safe, potent, thermostable RABV vaccine that could be delivered orally to wildlife or domestic animals would enhance current rabies control and prevention efforts.
Articulating Power Through the Parochial: The 1956 Armenian Church Election in Lebanon
Authors: Nalbantian Tsolin
Published: May 2017

A seemingly insular Armenian Church election that took place in Lebanon in February 1956 was simultaneously a site of contestation by Cold War powers and their proxies. Its disproportionately high coverage in the Lebanese press—and ensuing political intervention—provides an alternative view of the struggles for power between the United States and the USSR in Lebanon during the Cold War period. This election could have been understood as exclusively affecting Armenians in Lebanon and/or merely an entertaining anecdote of competition between Armenian religious figures. Instead, I argue that it is an opening to observe American-Soviet state competition for political influence in the region outside of the conventional case studies of the 1958 US marine intervention in Lebanon and the American government’s inability to prevent the Soviet suppression in Hungary in the aftermath of the Tripartite Aggression in Egypt in October 1956. And yet, this election must also concurrently be seen as a moment where the Armenian population of Lebanon made use of Cold War suspicions to designate a leader of the Armenian Church seen to suit their community’s interests. This article throws into relief the customary depiction and understanding of the Armenian population in Lebanon as temporary refugees and therefore not an integral part of the Lebanese nation-state by drawing out the use of Cold War rivalries.

Facing the Indonesian Media Conglomeration: Action of Preservation on Political Interest
Authors: Susilo Daniel
Published: May 2017

After 1999, Indonesia's Media became grown up. It is the implication of the fallen of the authoritarian regime, Suharto. The growth has another side effect about trends of media conglomeration. Indonesian Media Conglomerate such as Tanoesoedibjo, Tandjung, Paloh and Bakrie also have the background as a politician. Mass media are an efficient tool to change the mind of people.  Mass society theory makes several basic assumptions about individuals, the role of media, and the nature of social change. Media owner used their media for preserving his political influences. Facing this situation, Indonesian regulation about media ownership ignored by media owners. They used their power in the political area to get away from the regulation. Whereas, in Indonesian Law Number 32, issued on 2002 about Broadcasting Media, Especially on Chapter 36 verse 4 states, "broadcast content must be maintained neutrality and should not put the interests of a group". Many complain from the media audience, but no action from the government. The regulator doesn't enforce the law, especially at Broadcast Media. Most of the press uses the public sphere, who design for democratisation process, not for individual or political party's interest. Keywords: media conglomeration, Indonesia, Politics

Many soft white winter (SWW) wheat (Triticum aestivum L.) cultivars with high yield potential in the US Pacific Northwest lack adequate resistance to stripe rust or are only adapted to specific regions defined by annual precipitation. The objective of this research was to develop a SWW wheat cultivar with improved resistance to current stripe rust races and high yield potential across a wider range of climates. ‘Jasper’ (Reg. No. CV‐1124, PI 678442) SWW wheat was developed and released in September 2014 by the Agricultural Research Center of Washington State University. Jasper was tested under the experimental designations 5J061865‐11 and WA8169, which were assigned through progressive generations of advancement. Jasper is a semidwarf cultivar adapted to intermediate to high rainfall (>300 mm of average annual precipitation) wheat production regions of Washington, with acceptable yield potential in the lower rainfall areas (<300 mm of average annual precipitation). It has high‐temperature, adult‐plant resistance to the current races of stripe rust, is intermediate in height, has midseason maturity, and has an average test weight and high grain yield potential. Jasper has end‐use quality properties similar or superior to those of ‘Stephens’, ‘Puma’, and ‘Otto’.
Individual Traits, Personal Values, and Conflict Resolution in an Isolated, Confined, Extreme Environment

Published: May 2017

BACKGROUND: The study of personality traits, personal values, and the emergence of conflicts within groups performing in an isolated, confined, and extreme environment (ICE) may provide insights helpful for the composition and support of space crews for long duration missions.METHODS:
Studied pre/post and over the 2-yr period of the investigation were 10 Danish military personnel deployed to stations in Greenland on a 26-mo staggered rotation. Subjects completed the NEO PI-R, Triarchic Psychopathy Measure, and Portrait Values Questionnaire, and participated in structured
interviews. During deployment, questionnaires were completed biweekly and a cognitive function test once a month.RESULTS: Personality findings indicated a generally well-adjusted group, above average in positive personality traits [Conscientiousness T-score = 59.4 (11.41); Agreeableness
T-score = 54.4 (9.36)] and boldness. Personal values of benevolence and self-direction were highly rated. The decision when to “pick sides” and intervene during disagreements between group members was viewed as an important component of conflict resolution. There were no changes
in positive/negative affect or cognitive function over the annual light/dark cycle.DISCUSSION: The personal values of group members appear highly compatible for living in a small group ICE environment for an extended period. Disagreements between group members impact the functioning
of the entire group, particularly in regard to decisions whether to support one of the individuals or let the argument run its course. Extended training in strategies for conflict resolution are needed in planning for future long duration missions to avoid fault lines forming within the group.Corneliussen

The Internal Stakes of the 2005 Elections: The Struggle for Influence in Egypt's National Democratic Party
Authors: Collombier Virginie
Published: May 2017

Beyond the relative opening of the political system that characterized 2005 in Egypt — with the President being elected directly for the first time and the increased competition allowed during legislative elections — the 2005 elections also constituted an opportunity to
consider and evaluate the internal struggles for influence under way within the ruling National Democratic Party (NDP). In a context largely influenced by the perspective of President Husni Mubarak's succession and by calls for reform coming from both internal and external actors, changes
currently occurring at the party level may have a decisive impact on the future of the Egyptian regime.

Authors: MILOVANOVIĆ Bojan , BANJAD PEČUR Ivana , ŠTIRMER Nina
Published: May 2017

This paper presents a procedure for detecting and quantifying defects in reinforced concrete structures by us-ing the method of active infrared thermography (IRT). For quantitative analysis, a methodology of thermal stimulation of concrete specimens and post-processing of the gathered data was developed. Presented methodology uses principles of step heating (SH) thermography, pulsed phase (PPT) thermography, principal component thermography (PCT) and correlation operators technique. A short descriptions of the post-processing methods used in the research is also provided in the paper. All three post-processing methods i.e. PPT, PCT and correlation operators technique have shown the pos-sibility to enhance the defect detection in concrete structures in comparison to raw thermograms. According to the data accessible to the authors, in presented research, correlation operators and PCT post-processing techniques are being suc-cessfully used for the first time for defect detection within concrete structures. The results of the research clearly show the possibility of using active IRT for the detection and assessment of defect depth (quantification) in reinforced concrete structures with the measurement error within 10%.
Applications of stiffness-based evaluation method to element importance of truss systems
Authors: CAI Jianguo , JIA Wenwen , FENG Jian , WANG Fang , XU Yixiang
Published: May 2017

Two structural performance indexes, making use of eigenvalues of stiffness matrix, are presented in the study for the evaluation of element importance in the progressive collapse analysis of space trusses. Both indexes are based on the consensus that the element transferring higher loads in the load path is generally more important in the structural sys­tem. The first index is formulated as change of the smallest stiffness after removal of specific element, and the second in­dex is defined as determinant of the stiffness matrix. Several simple numerical examples are presented to investigate per­formance of the proposed indexes; and finally, a square pyramid space grid system is studied as an illustrative example.

Authors: ZHANG Lianying , CHEN Xi , SUO Yongqing
Published: May 2017

Work flow in lean construction has a significant influence on project performance. Uncertain work flow will lead to waste and reduce labor productivity. Reliable work flow will contribute to improving project performance. We found twenty variables affecting work flow reliability by literature review. In order to identify critical factors of work flow reliability and explore interrelationships among them, we designed a questionnaire to collect data, applied factor analysis to identifying critical factors, and put forward hypotheses on the basis of previous research and applied struc­tural equation model (SEM) to exploring interrelationships among the critical factors of work flow. Final model con­firmed nine hypotheses and denied three hypotheses. Besides, this paper discovered other interrelationship among the critical factors except for the hypotheses. The result of this research will help project managers understand work flow easily and take effective measures to improve work flow reliability, which will contribute to implement lean construc­tion successfully.
Energy utilizability concept as a retrofitting solution selection criterion for buildings
Authors: YANG Junjing , CHONG Adrian , SANTAMOURIS Mat , KOLOKOTSA Denia , LEE Siew Eang , THAM Kwok Wai , SEKHAR Chandra , CHEONG David Kok Wai
Published: May 2017

Retrofitting is widely explored as one of the energy conserving opportunities for existing buildings, in which both passive and active solutions are carefully evaluated. However, when different retrofitting solutions are combined and applied to a building, the total energy savings potential, which is less than the sum of the savings from applying the various individual retrofitting solutions, is considerably reduced and the synergies among the various technologies need to be understood and evaluated. In this study, the concept of utilizability is employed for the analysis of multiple energy retrofitting solutions in buildings and is defined as the ratio of energy savings derived from applying combined solutions to a building over the sum of individual energy savings from applying individual solutions. It is aimed at providing a better understanding of the combined retrofitting solutions. The sensitivity analysis on the utilizability value further pro­vides a selection criterion for retrofitting solution selection.
Comparison of stochastic prediction models based on visual inspections of bridge decks
Authors: ZAMBON Ivan , VIDOVIC Anja , STRAUSS Alfred , MATOS Jose , AMADO Joao
Published: May 2017

Due to a considerable amount of information required to support the decision-making processes, an increasing number of infrastructure owners use computerized management systems. Bridges, being complex and having significant impact on society, have often been the foundation for the development of these systems. In order to manage bridges effectively, condition prediction models are incorporated to the core of decision-making processes. Many of developed and applied stochastic prediction models show certain limitations. The impact of these limitations on deterioration pre­dictions cannot be objectively evaluated without direct comparison of prediction results. Hence, several stochastic pre­diction models based on condition ratings obtained from visual inspections of bridge decks are compared in this article. Models are described and implemented on the data of around 1100 reinforced concrete bridge decks from the ‘Infraes­truturas de Portugal’, a state owned Portuguese general concessionaire for roadways and railways. The statistical analy­sis of different models revealed significant deviations, particularly in higher condition ratings. Results indicate limited prediction capability of a simple homogeneous Markov chain model when compared with time- and space-continuous models, such as the gamma process model.
A Dark Asteroid Family in the Phocaea Region
Authors: Novaković Bojan , Tsirvoulis Georgios , Granvik Mikael , Todović Ana
Published: May 2017

We report the discovery of a new asteroid family among the dark asteroids residing in the Phocaea region the Tamara family. We make use of available physical data to separate asteroids in the region according to their surface reflectance properties, and establish the membership of the family. We determine the slope of the cumulative magnitude distribution of the family, and find it to be significantly steeper than the corresponding slope of all the asteroids in the Phocaea region. This implies that subkilometer dark Phocaeas are comparable in number to bright S-type objects, shedding light on an entirely new aspect of the composition of small Phocaea asteroids. We then use the Yarkovsky V-shape based method and estimate the age of the family to be 264 ± 43 Myr. Finally, we carry out numerical simulations of the dynamical evolution of the Tamara family. The results suggest that up to 50 Tamara members with absolute magnitude

may currently be found in the near-Earth region. Despite their relatively small number in the near-Earth space, the rate of Earth impacts by small, dark Phocaeas is non-negligible.

We report the analysis of the first resolved caustic-crossing binary-source microlensing event OGLE-2016-BLG-1003. The event is densely covered by round-the-clock observations of three surveys. The light curve is characterized by two nested caustic-crossing features, which is unusual for typical caustic-crossing perturbations. From the modeling of the light curve, we find that the anomaly is produced by a binary source passing over a caustic formed by a binary lens. The result proves the importance of high-cadence and continuous observations, and the capability of second-generation microlensing experiments to identify such complex perturbations that are previously unknown. However, the result also raises the issues of the limitations of current analysis techniques for understanding lens systems beyond two masses and of determining the appropriate multiband observing strategy of survey experiments.

We investigate the occurrence of radio minihalos—diffuse radio sources of unknown origin observed in the cores of some galaxy clusters—in a statistical sample of 58 clusters drawn from the Planck Sunyaev–Zel’dovich cluster catalog using a mass cut (M
500 > 6 × 1014
M
⊙). We supplement our statistical sample with a similarly sized nonstatistical sample mostly consisting of clusters in the ACCEPT X-ray catalog with suitable X-ray and radio data, which includes lower-mass clusters. Where necessary (for nine clusters), we reanalyzed the Very Large Array archival radio data to determine whether a minihalo is present. Our total sample includes all 28 currently known and recently discovered radio minihalos, including six candidates. We classify clusters as cool-core or non-cool-core according to the value of the specific entropy floor in the cluster center, rederived or newly derived from the Chandra X-ray density and temperature profiles where necessary (for 27 clusters). Contrary to the common wisdom that minihalos are rare, we find that almost all cool cores—at least 12 out of 15 (80%)—in our complete sample of massive clusters exhibit minihalos. The supplementary sample shows that the occurrence of minihalos may be lower in lower-mass cool-core clusters. No minihalos are found in non-cool cores or “warm cores.” These findings will help test theories of the origin of minihalos and provide information on the physical processes and energetics of the cluster cores.
The Stellar Initial Mass Function in Early-type Galaxies from Absorption Line Spectroscopy. III. Radial Gradients
Authors: van Dokkum Pieter , Conroy Charlie , Villaume Alexa , Brodie Jean , Romanowsky Aaron J.
Published: May 2017

There is good evidence that the centers of massive early-type galaxies have a bottom-heavy stellar initial mass function (IMF) compared to that of the Milky Way. Here we study the radial variation of the IMF within such galaxies, using a combination of high-quality Keck spectroscopy and a new suite of stellar population synthesis models that cover a wide range in metallicity. As in the previous studies in this series, the models are fitted directly to the spectra and treat all elemental abundance ratios as free parameters. Using newly obtained spectroscopy for six galaxies, including deep data extending to

for the galaxies NGC 1407, NGC 1600, and NGC 2695, we find that the IMF varies strongly with galactocentric radius. For all six galaxies the IMF is bottom-heavy in the central regions, with average mass-to-light ratio “mismatch” parameter

. Our results are also consistent with several earlier studies that were based on analyses of radial gradients of line indices. The observed IMF gradients support galaxy formation models in which the central regions of massive galaxies had a different formation history than their outer parts. Finally, we make use of the high signal-to-noise central spectra of NGC 1407 and NGC 2695 to demonstrate how we can disentangle IMF effects and abundance effects.
Chanter les territoires Sámi dans un monde plus-qu’humain
Authors: Aubinet Stéphane
Published: May 2017

À travers une description du joik, répertoire vocal pratiqué par les Sámi de l’Arctique européen, et des rapports qu’il entretient avec la constitution de territoires, cet article vise à contribuer au développement d’une géographie musicale attentive aux multiplicités de non-humains avec lesquels les interprètes et auditeurs humains cohabitent. Les chants de paysages et d’animaux permettent aux Sámi d’explorer le terrain et de guider leur attention vers leur environnement. La connaissance du terrain et le chant s’enrichissent mutuellement et contribuent à l’actualisation de territoires.
Les chants des poètes improvisateurs du Nordeste brésilien. Expression de l’attachement de migrants à leur terroir
Authors: Rougier Thierry
Published: May 2017

Les repentistas de Pernambuco, Paraíba et Rio Grande do Norte sont des poètes populaires qui répondent aux sollicitations du public en chantant des couplets entièrement improvisés. Ils expriment l’attachement des gens du Nordeste brésilien à leur culture et à leur terroir. Dans un contexte d’émigration et d’exode rural, ils portent une nostalgie (« saudade »). Les improvisateurs incarnent l’archétype du migrant, leurs performances contribuant à la perpétuelle redéfinition d’une identité.
La pensée critique dans la sociolinguistique en France
Authors: Boutet Josiane
Published: May 2017

La dimension critique a été aux fondements de la constitution de la sociolinguistique en France dans les années 1970. Je m’interroge sur le devenir de cette pensée critique, quarante ans plus tard. Après avoir exposé la conception bourdieusienne d’une discipline critique, je présente l’évolution de cette pensée dans la sociolinguistique française, selon trois étapes : les années 1970, période d’émergence d’une sociolinguistique critique ; les années de reflux (1990-2000) ; la situation actuelle caractérisée par une grande diversité scientifique. En quarante ans, une communauté scientifique s’est progressivement constituée à la fois sur un partage de principes théoriques et méthodologiques, et sur des controverses scientifiques, dont celle portant sur l’objet de la discipline. La sociolinguistique est en 2017 confrontée à la puissance des linguistiques formelles et à la dispersion intellectuelle du champ : pour y répondre, la sociolinguistique est en capacité de faire de l’implémentation sociale.
Langues et discours comme objets sociologiques : une illustration en sociologie de l’éducation
Authors: Hambye Philippe
Published: May 2017

Cet article plaide pour une approche du langage qui traverse les frontières disciplinaires instituées entre la sociolinguistique, l’analyse du discours et la sociologie. Après un bref retour sur le caractère indissociable des pratiques langagières et des pratiques sociales , j’essaie de montrer pourquoi cette conception théorique invite à dépasser les logiques de clôture disciplinaire. J’illustre enfin le positionnement que je défends sur le terrain de la sociologie de l’éducation et à partir des questions que pose le concept de capital culturel, en montrant ce que la prise en compte de la dimension langagière des pratiques sociales apporte à la réflexion sociologique.
Forty years of speaking (of) the same (object) language – sans le savoir
Authors: Silverstein Michael
Published: May 2017

Chacun des termes « sociolinguistique » et « anthropologie linguistique » suggère une orientation vers des disciplines d’encadrement différentes : la linguistique ou l’anthropologie, selon le cas. Pourtant, nous devons garder en mémoire que durant les quarante voire cinquante dernières années, l’objet de préoccupation scientifique de ces deux « entreprises » a été la plupart du temps le même : la corrélation entre la forme discursive, intermédiaire universel de l’interaction sociale, et le contexte se rapportant à la communication produite. Il est certain que l’accent a été mis sur des aspects différents de cette question centrale, incarnant peut-être une fonction propre à ces deux cadres disciplinaires. Mais il est important de voir l’intérêt croissant que suscitent la sociolinguistique et l’anthropologie linguistique en opposition à certains courants influents de la linguistique et de l’anthropologie, et se résumant à ce que l’on pourrait nommer « le fonctionnalisme sémiotique ».
La performance au carrefour des arts et des sciences sociales : quelles questions pour la sociolinguistique ?
Authors: Greco Luca
Published: May 2017

Le but de cet article sera de reconstruire, d’une part, la généalogie du concept de performance dans les arts plastiques et dans les sciences sociales (sociologie, linguistique, anthropologie) et de montrer, d’autre part, comment, à la fin des années 1950 et au début des années 1960, aux États-Unis, les questionnements autour d’une nouvelle conception praxéologique de l’art croisent d’une façon intéressante et surprenante une vision dramaturgique de l’action sociale en tant que performance. Si dans les arts plastiques, l’émergence de la « performance » en tant que pratique artistique montre, dès son émergence, un intérêt particulier pour le langage tout en interrogeant les dichotomies « scène vs coulisse », « vie vs art », etc. (Kaprow 1958, Cage 1965), nous observons, dans les sciences sociales, avec les travaux pionniers de Gurvitch (1956) et de Goffman (1959), une vision des interactions sociales au prisme de la performance et de la théâtralité. On interrogera ainsi les conditions historiques d’émergence d’une telle rencontre, les points de dialogue possibles entre art et sciences sociales et les enjeux théoriques et épistémologiques posés par l’art et la performance pour l’étude des pratiques interactionnelles et pour l’histoire des idées en sociolinguistique.
L’odyssée de l’espace en sociolinguistique
Authors: Auzanneau Michelle , Trimaille Cyril
Published: May 2017

L’article s’intéresse à la façon dont la sociolinguistique a, au cours de son histoire, intégré et pensé différents niveaux de l’espace comme paramètres des écologies sociolangagières. Après un bref aperçu d’appréhensions « pré-sociolinguistiques » des relations espace/langage, il recense des approches qui ont induit des « tournants » dans l’articulation du spatial et du langagier et contribué à construire un corpus théorique et un répertoire de pratiques empiriques. Dans la dernière partie, les auteurs rendent compte des renouvellements des approches et des questionnements induits notamment par l’attention accrue portée aux sujets et aux mutations sociales contemporaines qui provoquent des brouillages diatopiques telles que la démultiplication des modalités communicationnelles de mobilités.
