Perspectives on Digital Scholarship: Exploring Conceptual Landscape and Practices in Latin America
No full textThe concept of Digital Scholarship (DS) defines new forms of professional academic practices linked to the changing cultural, social and working context of the digital age. In this chapter, the authors compare the international debate on the topic with the research trends that may be connected with DS inthe Latin-American scenario. From the focus on DS as a changing professional field of practice, that of academics, and its specific transformation by digitality to other more evolved perspectives, i.e. the academic profession as a specialized research strand, the authors consider the different approaches, discourses and cases about academics professional practices and development in Latin America andexplore the trends and peculiarities that will determine the rise and development of digital scholarship as a field of research in the region.Fil: Constantino, Gustavo Daniel.

Philaethria pygmalion subsp. metaensis Constantino & Salazar, n.ssp.
No full textPhilaethria pygmalion metaensis Constantino & Salazar, n.ssp. (Fig. 12) Diagnosis. P. pygmalion metaensis is recognized from P. pygmalion pygmalion by the dark brown inner postdiscal band on the ventral surface of the hind wing which is wider, the FW postmedial green area larger, and the HW postcellular spots smaller. P. pygmalion metaensis flies in open areas (savannas in the Orinoco basin) unlike P. pygmalion pygmalion that flies in dense forest in the Amazon basin. Description. Forewing length 49–52 mm in males and 52–55 mm in females. Sexes similar. Dorsal forewing ground color black with light green-lemon bands like in P. dido. Ventral surface of the hindwings with inner postdiscal band dark brown and wide (narrower in P. pygmalion pygmalion), bone white medial postdiscal band very narrow, outer postdiscal band black. Postcellular spots small (larger in P. pygmalion pygmalion). Submarginal band dark brown. HW submarginal cellular spots diffuse and continuous. Ventral side of forewing with anal cell bar black. Postmedial green area large with the band between veins M 2 - M 3 large (very reduced or almost absent in P. pygmalion pygmalion). Subapical spot large and rounded. Type material.

(JAS) Haploid chromosome number: n= 29 (voucher specimen fig. 12) for material examined from Rio Ariari (Meta) Etymology: The name refers to the Department of Meta in Eastern Colombia in which this subspecies is found. Distribution and habitat. P. pygmalion metaensis flies in open areas and grasslands in the vast savanna of the Orinoco basin (Rio Meta, Rio Ariari, Llanos Orientales) and along the eastern slope of the Cordillera Oriental in Colombia. It is possible that P. pygmalion metaensis may occur in the state of Apure in Venezuela, down the Orinoco river since both countries share the same savanna ecosystem (Llanos Orientales) but no records available from Venezuela were found for this subspecies. P. pygmalion metaensis flies sympatrically with P. dido dido in E. Colombia. Host plant. reared on Passiflora edulis (Passifloraceae) in E. Colombia (Meta) (Gregory Nielsen pers. comm.).

Concepciones, modelos y propuestas alternativas para la investigación del aprendizaje en red. Una aproximación desde la experiencia del proyecto REDES
No full textPedagogical practices are changing drammaticaly, through the development of both the Web and theories of learning (socio-constructivism, social constructionism, theory of networks, etc). This is leading to an increasing interest on interactions among teachers, students, and technology. Indeed, the analysis of such pedagogical practices claims for new methodological approaches in order to raise the complexity of communicational interactions (as base of learning and knowledge construction) in the new learning contexts on the Web. In this sense, there has been a shifting from quantitative to qualitative methodologies on the several models of analysis of interactions. Nevertheless, there is still lack of studies in online learning procesess, that is to be linked to the fact that interaction analysis studies have left behind the study of discursive manners in the real contexts of human activity, where people get involved and construct jointly their discurses. From the other hand, few attention has been paid to resourse other than text. Considering this background, this research group has started to work on an alternative proposal in order to develop an approach that will be able of integrate several analysis models, allowing hence to cover the complexities of communicational interactions in learning contexts. The authors of this article believe, in that sense, that the triangulation among interactions with resourses and participants on the net is tightly connected to the construction of the learning context (which implies the communication context) hic et nunc.
Therefore, the aim of this article is to introduce a perspective about the methodological concern with regard to the shifting of pedagogical practices within changing social arena where the Web is having a crucial impact. The article is divided hence in three parts: 1) pedagogical practices shifting; 2) models of analysis of online communicational interactions in learning processes; 3) alternative proposals to the study of such phenomenon.
An attempt of introduce a general picture is made, in order to allow more systematic and deep approaches to research in the field
Profesión Académica Digital: Encuadre conceptual e impacto en los escenarios universitarios latinoamericanos.
No full textOnline Teaching and Learning: Going Beyond the Information Given
No full textIn this chapter three basic features of online teaching and learning representing a paradigmatic change in the field are explored regardless the tensions/resistance generated on academics: (1) the shared construction of knowledge through digital instructional interaction; (2) the growing curriculum flexibility facilitated by an open and boundless Internet, and (3) the progress of multimodal digital formats, which demand adequate communication skills from teachers and students. The first aspect entails the possibility of collaborative knowledge creation through online communication, which requires dialogic scaffolding grounded on discourse comprehension and production strategies, going beyond the mere transmission and exchange of information. The second issue reflects the expansion and openness of the knowledge available on the Web, turning closed curricula based on limited resources into obsolete and reductive options. Third, multimodality involves an expressive leap, a change in meaning design, given the linguistic components are no longer the primary vehicle of meaning, which rather arises from a synergic mix of elements such as image, sound, and motion. These issues are approached and exemplified concerning the complex Latin American context, where the changes in the academic profession (scholarship) brought about by digitality (digital scholarship) have had a varying impact. Furthermore, some of the biggest challenges that higher education presents in LA nowadays are related, first, to the sociopolitical demands for higher education for all citizens, in a massive form that does not match the instructional models of online education on which the personal relationship between teachers and students is essential. Second, the need for empowerment of the Latin American faculty team in general, and not just some elite of professors in some elite universities. The conclusions can be summed up by stating that the paradigmatic triad (i.e., shared knowledge construction, Web as curriculum and multimodal communication) allows us to go “beyond the information given”, re-signifying Bruner’s powerful expression

Competence based tutoring online: a proposal for linking global and specific E-learning Models
No full textThe paper suggests crossing global e-learning models with specific ones so as to determine their possible correlation in order to infer online tutor competence profiles. These are found at the intersection of the pyramid, matrix and e-learning instructional design models. Hypothetical setups of the pyramid e-learning systems are discussed. The competence matrix is described in more detail as a complex and potentially useful instrument to guide OLT training and evaluation. It is concluded that the synergy resulting from the interplay among the competence matrix, e-learning instructional design models and e-learning environments will make it possible to assess instrument potential and conceptual schema appropriateness. It will also show their limitations, with a view to improving them
Labiotermes oreadicus Constantino, new species
No full textLabiotermes oreadicus Constantino, new species Holotype: soldier, part of lot UnB 241, 27.ii. 1997, R. Constantino Typelocality: Brazil. Goiás State. Serra da Mesa (Fig. 20). Paratypes: workers, same data as holotype (UnB 241). Etymology: Oréades corresponds to the Cerrado biome in the classification proposed by the German botanist von Martius. The word comes from the Latin oreadis and the Greek oreias, mountain nymph. In this case, oreadicus means inhabitant of the Cerrado. Imago. Unknown. Soldier (Figs. 8 A–F, 11 H). Head capsule subrectangular, with parallel sides in dorsal view. Frontal tube short but conspicuous, with broad tip, upturned. Top of head convex in profile. Antenna with 16 articles. Labrum wider than long; sides convex. Mandibles moderately elongate and robust. Left mandible: cutting edge between apical and 1 st marginal slightly Sshaped; cutting edge between marginal teeth slightly concave. Right mandible with two marginal teeth, about the same size. Front coxa without a lateral projection near base. Head capsule and labrum brownish yellow; thorax and legs lighter than head capsule; tergites and sternites yellowish. Head capsule with numerous short and straight bristles of relatively uniform size; postmentum with numerous bristles on anterior half; pronotum with many bristles on margins and surface; mesonotum with metanotum with tergites and sternites densely covered with bristles and fine hairs. Measurements in Table 2. Comparisons. The mandibles and postmentum of L. oreadicus are distinct (Fig. 11 H). It is also much larger than most other species, except L. guasu, which has very few bristles on the head. Worker (Figs. 8 G–J, 13 H, 14 E, 15 O –P, 16 H). Head capsule and postclypeus with numerous bristles. Pronotum with numerous bristles on anterior lobe and a row of bristles on posterior margin. Mesonotum with a line of bristles on posterior margin. Front coxa without any projection near base. Antenna with 15–16 articles. Fontanelle large and rounded. Enteric valve armature with 3 distinct ridges of unequal sizes covered with dense, fine, and long hairs, and 3 vestigial ridges with long hairs. Mixed segment withtwo mesenteric lobes; large with a very narrow part closer to the mesenteron and an oval distal part; small lobe narrow and elongate. Measurements in Table 3. Comparisons. The workers of L. oreadicus can be recognized by its large size and the absence of a projection on the front coxa. Among all other species, only L. guasu and L. labralis lack this projection, but their heads have very few bristles. The enteric valve of L. oreadicus is distinct (Fig. 16 H).Published as part of Constantino, Reginaldo, Acioli, Agno N. S., Schmidt, Karen, Cuezzo, Carolina, Carvalho, Sérgio H.
