Vestire l'etnicitĂ
The article analyzes the relationship between clothing and ethnic identity in the works of Greek writer Lucian of Samosata. We concentrate on importance of clothes in the construction of foreigners’ “diversity” and we explain the symbolic role of the assumption of Greek attire in foreigners’ process of Hellenization. We also examine how Greek clothing represents, for Greek people in Roman context, a mark of ethnic and cultural differentiation
Narrazioni affettive nella gestione del diabete di tipo 1. Studio pilota di una triade familiare
Il diabete mellito tipo 1 è una malattia cronica dovuta ad un disordine metabolico ad eziologia multipla. Definita
da Bury (2005) come una “discordanza biografica”, il suo trattamento si basa sul coinvolgimento attivo delle famiglie e
rende necessario una riorganizzare della vita quotidiana del paziente e della famiglia. Lo studio ha lo scopo di analizzare le
interazioni di una triade familiare in termini di modalità enabling (facilitante) e constraining (ostacolante) e l’influenza sulla
salute del ragazzo di queste modalitĂ comunicative. Gli strumenti self report, come la Scala degli ambiti di discussione familiari
(Gambini, 2008) per il tema scelto e il Sample Diabetes Questionnaire (SDQ) dello Stanford Patient Education Research
Center (2007), per la salute del paziente, hanno affiancato lo strumento Constraining and Enabling Coding System (CECS;
Hauser, et al.1991 adattato da Chiarolanza, et al. 2016) per le analisi dell’interazione videoregistrata di una triade familiare.
Dall’analisi delle interazioni emerge che le forme comunicative nella triade si orientano verso modalità comunicative della
dimensione cognitiva vincolante. Questo sembra interferire sul monitoraggio della glicemia e sul rapporto del figlio col
medico. La modalità con cui i membri di una triade riescono a coordinarsi o non, dunque, durante un’interazione sembra
avere effetti sulla salute dell’adolescente sia declinata come qualità delle relazioni familiari che di benessereThe type 1 diabetes mellitus is a chronic disease caused by a metabolic disorder
with multiple etiologies. Defined by Bury (2005) as a "biographical disagreement ", its
treatment is based on the active involvement of families and makes it necessary to
reorganize both patient daily life and his/her family one. This paper aims to
analyze the interactions of a family triad in terms of enabling and constraining style
and how this type of communication has an impact on the child health. We utilized
for this study self-report questionnaires and Constraining and Enabling Coding System
(CECS; Hauser, et al.,1991 adapted by Chiarolanza, et al., 2016) for analysis of a
family triad interaction. Results showed that interactive communication in the triad
are oriented towards constraining cognitive dimension. This could interfere with
blood glucose monitoring and the patient relationship with integrated team care.
Members of a triad can coordinate or not during a family interaction and this could
have effects on adolescent health in terms of quality of family relationships and
well bein
LMX Differentiation and Group Outcomes: A Framework and Review Drawing on Group Diversity Insights
In this review, we address inconsistencies and a lack of clarity in the study of leader-member
exchange (LMX) differentiation and group outcomes. We do so by drawing on another highly vis-
ible group dispersion literature in the management domain, group diversity, based on the recogni-
tion that LMX quality is a characteristic on which group members vary. Utilizing insights from
Harrison and Klein’s typology of group diversity constructs, we introduce a framework that
specifies the meaning and shape of three variations of differentiated leader-member relationships
in groups and connects each construct with implications in terms of theorizing and measurement.
Specifically, our framework conceptualizes LMX differentiation as LMX separation (dispersion in
LMX relationships as disagreement or opposition regarding an opinion, perception, or position),
LMX variety (dispersion in LMX relationships as distinctiveness in kind, source, or category), and
LMX disparity (dispersion in LMX relationships as inequality in concentration of valued social
assets or resources). We then apply this framework to conduct a systematic review of the LMX
differentiation literature with particular attention to alignment among a study’s descriptions of the
construct, application of theory, expected group outcomes, and construct measurement. Finally,
we offer recommendations for future research and for applying our framework to enhance reli-
ability, validity, and generalizability in studies of LMX differentiation and group outcomes

Análisis hidrográfico de la laguna los Flamencos durante 2008-2009 (Partido de Saavedra, Provincia de Buenos Aires)
Se estudiĂł la hidrografĂa de la laguna Los Flamencos localizada en la provincia de Buenos Aires, Argentina. Se midieron parámetros fĂsico - quĂmicos en la columna de agua como asĂ tambiĂ©n parámetros morfomĂ©tricos de la laguna en los años 2008 y 2009. Se realizaron ensayos de infiltraciĂłn y se analizĂł la granulometrĂa de los sedimentos en el contorno del cuerpo de agua. Para evaluar la disponibilidad de agua en el área de estudio, se llevaron a cabo balances hĂdricos para el perĂodo de estudio segĂşn la metodologĂa de Tornthwaite. La laguna Los Flamencos es un tĂpico lago de llanura muy poco profundo que no presenta una marcada estratificaciĂłn tĂ©rmica. Es oligohalino y de acuerdo al Ăndice de estado trĂłfico su condiciĂłn fue mesotrĂłfica. El pH del agua es alcalino y es rica en oxĂgeno. Los valores de nitratos, nitritos, fosfatos y silicatos se encuentran dentro de los parámetros tĂpicos de lagunas templadas. La laguna presenta forma circular dividida en dos cuerpos de agua. El área en el cuerpo mayor y menor fue 3.76 y 0.64 km2, respectivamente. Predominaron suelos limo-arcillosos con baja capacidad de almacenaje y altamente impermeables. Los balances hĂdricos durante la Ă©poca estival indicaron condiciones de dĂ©ficit significativas, evidenciando la importancia de la evaporaciĂłn en la hidrografĂa de la laguna.Fil: Villarreal, MarĂa Laura.

Drought impact in the region of the watershed the Sauce Grande lagoon (Buenos Aires province, Argentina)
La distribuciĂłn e intensidad de los extremos hĂdricos provoca un impacto directo sobre las actividades humanas. Las caracterĂsticas particulares de los eventos secos y hĂşmedos ocurridos en la regiĂłn de la cuenca hidrográfica de la laguna Sauce Grande, durante el perĂodo 1971- 2010, se analizan mediante la aplicaciĂłn del ĂŤndice de severidad de sequĂa de Palmer. El 49% de los casos analizados correspondieron a sequĂas dĂ©biles, e incipientes. Los valores más extremos de eventos secos (-4.31) ocasionaron daños irreparables en los rendimientos de granos, que disminuyeron un 19% respecto al promedio actual. Durante los meses estivales se observaron los casos secos severos y extremos (12%). Se identificaron los perĂodos secos que mayor injerencia tuvieron sobre la producciĂłn agrĂcola ganadera de la regiĂłn, sucedidas durante los años 2008 y 2009, la relaciĂłn existente entre los valores de los Ăndices severos y extremos en la morfometrĂa de la laguna y estuario del rĂo Sauce Grande.The distribution and intensity of extreme water causes a direct impact on human activities. Dry and wet events in the region of the watershed of the Sauce Grande lagoon during the period 1971 - 2010 are analyzed through the application of Index of Palmer drought severity, 49% of the cases analyzed corresponded to weak, and emerging drought . The most extreme dry events values (-4.31) caused irreparable damage yields, which decreased by 19 % compared to the current average . During the summer months the severe and extreme (12 %) cases were observed. Dry periods had greater influence on livestock farming in the region, occurring during the years 2008 and 2009, the relationship between this values of the indices and severe extremes in the morphometry of the lagoon and the Sauce Grande estuary were identified.Este trabajo fue financiado parcialmente por subsidios del CONICET, proyecto redes PAMPA 2, Universidad Nacional del Sur y el Interamerican Institute for Global Change Research (IAI) CRN 3038 (under US NSF award GEO-1128040)
Nystagmus in Infantile Pompe Disease: a new feature?
We describe a 3 month-old female floppy infant with hypertrophic cardiomyopathy, serum en-
zyme levels, which were characterized by an aspartate aminotransferase level of 144 U/l, alanine transaminase
240 U/L and creatine kinase level of 543 U/l. On the basis of the clinical signs and laboratory results, acid
α-glucosidase activity was determined from dried blood spots resulting lower than the normal range (0.2
mmol/L/h: normal reference range: 1,86-21,9 mmol/L/h) and leading to a diagnosis of infantile Pompe dis-
ease. She also showed multi-directional nystagmus. Refractive errors, ptosis and strabismus are described in
infantile Pompe Disease, while nystagmus is rarely reported before. Therefore with this paper we highlight an
atypical ocular symptom, whose uncertain pathogenesis, to be taken into consideration, because by now, with
increasing survival with ERT, new phenotypes of Pompe disease are taking shap

Caracterización del fitoplancton y estado trófico de la laguna Sauce Grande (provincia de Buenos Aires, Argentina) en el otoño de 2010
The composition and abundance of the phytoplankton in the Sauce Grande Shallow Lake were studied during the autumn of 2010. Three sampling sites were established: In the output Sauce Grande River (E1), at the entrance of the Sauce Grande River in the water body (E2) and in the deepest sector of the water body (E3). Sixty taxa were identified, belonged to Chlorophyta (50%), Heterokontophyta (27%), Cyanobacteria (20%) and Dinophyta/Euglenophyta (3%). Phytoplankton abundance ranged between 84500 and 340600 ind/ml. No differences were observed in total phytoplankton abundances among sampling stations, but significant differences among sampling dates were found. Planctonema lauterbornii Schmidle (Chlorophyta) was the dominant species with abundances up to 70600 ind/ml. Several salinity indicators (as Chaetoceros muelleri, Cyclotella aff. meneghiniana and Protoperidinium achromaticum) and eutrophication indicators (as Microcystis aeruginosa and Pediastrum boryanum) were registered. Besides, representatives of Cyanobacteria putative toxic-bloom producers (as species of Anabaena, Anabaenopsis, Aphanocapsa and Microcystis) were identified. This shallow lake is classified as eutrophic according to Carlson TSI based on chlorophyll a. The high phytoplankton abundance and the low Secchi disk readings allow defining the Sauce Grande Shallow Lake as “turbid” and phytoplankton dominated.Fil: Ferrer, Nora Cristina.

Physiochemical responses of Ailanthus altissima under the challenge of Verticillium dahliae: elucidating the decline of one of the world’s worst invasive alien plant species
Natural infections of Verticillium spp. (Fungi, Ascomycota) on Ailanthus altissima have suggested to consider the biological control as a promising strategy to counteract this invasive plant, which is otherwise difficult to control by traditional mechanical and chemical treatments. Verticillium wilt is able to lead plants to death, throughout a pathogenic mechanism including vessel occlusions and production of degrading enzymes and phytotoxins. In this study, a 10 weeks open air pot experiment was set to investigate the ecophysiological and biochemical responses of Ailanthus trees artificially inoculated in the trunk with the V. dahliae strain VdGL16, previously isolated in Central Italy from the same host. Inoculated plants showed visible injuries starting from 2 weeks post inoculation (wpi), that progressively developed until a final severe defoliation. The fungal infection rapidly compromised the plant water status, and photosynthesis was impaired due to both stomatal and mesophyll limitations from 4 wpi, with subsequent detrimental effects also on PSII activity. Moreover, the disease altered the translocations of nutrients, as confirmed by cation and carbohydrate contents, probably due to a consumption of simple sugars and starch reserves without replacement of new photosynthesized. An accumulation of osmolytes (abscisic acid and proline) and phenylalanine (a precursor of phenylpropanoids) was also reported at 8 wpi, this being a response mechanism that needs to be further elucidated. However, the activation delay of such defence strategy inevitably did not avoid the premature defoliation of plants and the decline of physiochemical parameters, confirming the key role of Verticillium in Ailanthus decay
