title: An Overview About Ultrastructure of Kranz Anatomy in Cyperaceae (Poales)

description: Abstract An overview about ultrastructure of Kranz anatomy in Cyperaceae (Poales) - The ultrastructure of the Kranz tissues in Cyperaceae species with the four types of Kranz anatomy (chlorocyperoid, eleocharoid, fimbristyloid and rhynchosporoid) was studied and compared with species already described in the literature, with the goal verifying the occurrence of patterns for the Kranz types. In addition, chloroplasts and mitochondria were quantified for the first time for all Kranz types. The chloroplast’s structure is similar in the mesophyll cells (PCA) in the four Kranz types, but differs in some features in the bundle sheath cells (PCR). In the chlorocyperoid and rhynchosporoid types the bundle sheath cells (PCR) present centrifugal or scattered chloroplasts with convoluted or parallel thylakoids. In the eleocharoid types, the chloroplasts are scattered with parallel thylakoids. The fimbristyloid type presents centrifugal chloroplasts with convoluted and parallel thylakoids. To eleocharoid and fimbristyloid types and to Cyperus and Pycreus (chlorocyperoid) was observed pattern in the chloroplasts position. In most of the studied species the number of mitochondria in the bundle sheath cells (PCR) is significantly higher than in the mesophyll cells (PCA) and this result diverges from the results found in previous studies.

title: The genus Piper (Piperaceae) in the Mata das Flores State Park, Espírito Santo, Brazil

description: Abstract The conservation and management of the Atlantic Forest depends upon reliable knowledge about how many and which species this biome shelters. Floristic inventories have an important role in this process, especially when conducted in poorly known remnants, with a high conservation priority. This paper presents the study of the genus Piper (Piperaceae) in the Mata das Flores State Park, Castelo municipality, Espírito Santo state (ES). The study was based on the analysis of dried specimens, as well as those observed in the field, from February 2012 to August 2015. Twenty species of piper were identified. Amongst these species, Piper dilatatum, P. macedoi and P. piliovarium were recorded for the first time for the Espírito Santo state. Piper bicorne, an endemic species from ES and known only for the Santa Leopoldina municipality, had its geographical distribution expanded to the Castelo municipality. Most of the Piper species in the MFSP occur in valleys, and they are commonly found near watercourses. This is worrying given that these areas are just the most affected by the expansion of the rural and urban areas that surround the Park.

title: In vitro culture of Epidendrum nocturnum (Orchidaceae)occurring in the Cerrado in Central-West region

description: Abstract Orchids can be propagated in vitro in aseptic culture media or in symbiosis with mycorrhizal fungi. Epidendrum nocturnum occurs in areas of Cerrado and this study aimed to mycorrhizal fungi visualization in their roots and its asymbiotic growing their seedlings in different media and in vitro mycorrhization. In asymbiotic development was tested three culture in a test and, another test, alternative formulations of medium Knudson C modified with addition of fruit pulp. Mycorrhizal fungi orchids were used in in vitro mycorrhization. Pelotons were visualized in the roots of E. nocturnum. The medium Knudson C modified statistically different from the others, the two light intensities, in the first test. In the second test, after seven months, with the alternative formulation means were not statistically different from each other. In vitro mycorrhization plantlets with isolated fungal En07 (Waitea circinata) showed greater visual effect compared to other treatments, but there was no statistical difference with control. The media with alternative formulation and Knudson C modified can be used in vitro development of E. nocturnum, and the isolated fungal En07 can be used in order mycorrhization of this orchid conservation strategies.

title: Atypical mating system in two Rubiaceae species: distyly with partial self-incompatibility in the thrum morph?

description: Abstract Distylous species have populations with two floral morphs. The pin morph has long pistils and short stamens while the thrum morph presents short pistils and long stamens. Usually heterostylous plants present a diallelic system of incompatibility and morphs occur in a 1:1 ratio (isoplethy) in the populations. Different forms of variations occur in distylous species, such as the presence of self-compatibility, anisoplethy and variation in the reciprocity level between anthers and stigmas of the two floral morphs. The aim of this study was to investigate the occurrence of the distylous characteristics in two Rubiaceae species. For this purpose, morph ratio, reciprocal herkogamy, incompatibility system and flower visitors of Psychotria deflexa and Declieuxia fruticosa were studied. Both species have the two floral morphs in equal ratio, high reciprocity values for height of the reproductive whorls of the floral morphs and were visited only by insects. However, the thrum morph on both species presented partial self-incompatibility. Within the Rubiaceae, even in distinct phylogenetic groups, weakening or breakdown of distyly seems to occur in similar patterns, but deviations in the incompatibility system have been mostly recorded for the pin morph of distylous species. In the studied species the populations had equal morph ratio despite the pseudocompatibility of the thrum morph, which indicates that factors such as high reciprocal herkogamy and possibly efficient pollination services could promote the maintenance of distyly in these species.

title: The flora of Malaysia projects

description: Abstract Malaysia has an estimated 15,000 species of vascular plants. Located in the Malesian region, its affinity is Sundaic, having common elements with Sumatra, Java and Palawan. The two halves of Malaysia, Peninsular Malaysia extending from mainland Asia and East Malaysian states of Sabah and Sarawak on the island of Borneo have their own distinct floristic components. Peninsular Malaysia has about 8,200 species of vascular plants and Sabah and Sarawak have an estimated 12,000 species. The flora of Sabah and Sarawak is generally richer than that of Peninsular Malaysia. Due to historical reasons, the flora of Malaysia project is planned in a phased approach. The Tree Flora of Sabah and Sarawak project, initiated in 1991, represents the first systematic modern attempt to document some of the important plant families of these two states. It would take at least another ten years to complete this project. It is estimated that the Flora of Peninsular Malaysia project, initiated in 2005, will take at least 20 years to complete. To achieve these ambitions, there must be continual support in skilled manpower and fund allocations.

title: Heterospecific pollen deposition among plants sharing hummingbird pollinators in the Brazilian Atlantic Forest

description: Abstract Hummingbirds are the most important group of pollinating birds in the Neotropics and tend to use, concomitantly, more than one plant species as food source. Pollen may be mixed on hummingbirds' body due to the visits to different plant species; therefore, these birds may promote heterospecific pollen deposition (HPD). The hummingbirds potential to promote HPD, the occurrence of HPD and its implications in plant reproduction are scarcely known in the Atlantic Forest. We have studied the transport of pollen by three hummingbird species from the Brazilian Atlantic Forest. We have also checked the actual HPD occurrence under natural conditions in two plant species, namely Canistropsis seidelii and Psychotria nuda. Moreover, we investigated Nidularium innocentii reproductive system evaluating the effect of HPD on its reproduction by simulating a pollen mixture pollination. We found hummingbirds transporting heterospecific pollen mixtures on their bodies, which in turn were deposited onto stigmas of different species. We have also found that mixed pollen deposition had negative effect on the fitness of N. innocentii. We conclude that hummingbirds carry pollen mixtures at the same body parts, leading to potential HPD at the community level. Moreover, hummingbird-plant communities in the Atlantic Rainforest show remarkable similarities in temporal organization and interaction pattern. This suggests that HPD may be a widespread phenomena in these communities.

title: Flora of the Usina São José, Igarassu, Pernambuco: Erythroxylaceae

description: Erythroxylaceae has a pantropical distribution and presents about 240 species in four genera. Erythroxylum is the only genus in the Neotropics and in Brazil 123 species are recorded, with the highest diversity in the Atlantic Forest, especially in the Northeastern region of the country. The Atlantic Forest of Northeastern Brazil is considered the most threatened part of the biome, however this is the area with the highest diversity of species of Erythroxylum, although, the region still requires floristic and taxonomic studies. Thus, this study aimed to inventory the species of Erythroxylaceae from forest fragments at Usina São José (Igarassu, state of Pernambuco), and it is part of the survey of the flora of this area. The study was based on morphological analysis of specimen deposited the collections of the main Brazilian herbaria and also in the analysis of specimen collected in the field. Eight species were recorded: Erythroxylum citrifolium, E. mikanii, E. mucronatum, E. nitidum, E. rhodappendiculatum, E. rimosum, E. squamatum, and E. subrotundum. Among them, three species are first recorded to the state. An identification key, descriptions, illustrations, and comments on habitat, and geographic distribution of the taxa are presented.

title: Class Condition and Educational Performance in Brazil

description: Abstract: This paper analyzes the effects of social class on the educational performance of young Brazilians students. Our theoretical approach in this study is based on Pierre Bourdieu’s concept of social class. We opted for a quantitative methodology using the database of the Basic Education Evaluation System (Saeb) tests carried out in 2013. We used descriptive statistics, correspondence analysis and multiple linear regression. Empirical results showed the persistence of the effects of social class on academic performance, although these results coexist with the impacts of variables related to schooling, individual life story and pedagogical aspects.

title: Digital Literacy for Older Adults: perceptions about teaching-learning

description: Abstract: Digital literacy programmes for the elderly propose to expand digital skills and competences; yet, knowledge about the methodological and teaching approaches in these interventions is scarce. The study aimed to verify the optimising factors in the teaching-learning process in digital literacy programmes for older adults, based on students’ perceptions. Using the content analysis technique, two main categories were identified among the contributions of 278 participants. It was concluded that the human aspects should be valued by the instructors in the teaching-learning process for older-adult students, mainly, by demonstrating the qualities of being patient, calm and attentive.

title: A Local Regulatory Strategy for Basic Education in Rio de Janeiro

description: Abstract: This paper explores data about the performance of municipal schools in Rio de Janeiro during the first years of basic education to show that the regulatory instruments currently employed by the federal government must be complemented by a strategy that focus on local factors. Using data about the geographical location of Rio de Janeiro municipal schools and their performance at IDEB, we were able to pick out neighboring schools that achieved diametrically opposed results, despite serving students with comparable socioeconomic status. This reality suggests that bottom-up regulatory instruments might be employed efficiently. There is, however, a normative gap in that regard, with a strong prevalence of top-down public policies currently in place.

title: Ten Years Later: the meanings behind EYA teachers’ questions

description: Abstract: This paper presents a summarized analysis of teachers’ questions on the Education of Youths and Adults (EYA), across different areas of the Brazilian State of Rio Grande do Sul, between the years 2002 and 2004, as well as ten years later, from 2012 through 2014. This is a qualitative comparative research, with questions collected from written records and by teachers’ adherence, aiming to verify the effects of the meanings produced. The results, based especially on the Discourse Analysis by Pêcheux (1997, 1999 and 1987), point out that part of the meanings produced are updated again throughout the periods, uncovering that the discontinuities in the public policies of EYA teachers’ continuing educational training produce effects of a sense of circularity.

title: When someone Talk Politics to Me, I am Reminded of the Romans: Chilean high school students’ frameworks for making political use of history

description: Abstract: This article examines how Chilean high school students who are involved in student protests demonstrate and make use of their understandings of politics and history, in order to inform and orient their own political actions. Based on fieldwork conducted in 2014 in a Chilean public high school, I use discourse analysis to examine students’ interviews as a particular kind of social work. In these interviews, I argue that students were displaying and participating in the constant production of coherent frameworks in which history and politics are connected. Students’ understandings of history and politics inform and affect each other, as well as become significant in their citizenship education.

title: The Work on Oneself: musings on Wittgenstein’s legacy for philosophy of art and art education

description: Abstract: The present text discusses Wittgenstein’s later works. We attempt to establish the following: (A) Wittgenstein’s later philosophy was first understood by Morris Weitz as an opportunity to develop new ideas on aesthetics and philosophy of art, although Wittgenstein himself haven’t made those developments. (B) Weitz’s interpretation of Wittgenstein jumpstarts a debate concerned with definitional aspects within these fields. (C) This debate is vividly ongoing and one of its most recent figures is Noël Carroll. (D) Carroll’s methodological account for art identification without essential definitions is a relevant response to other accounts within the field, especially to Weitz. (E) Because Carroll’s account evokes art identification as something oriented by language, critique and narrative making, contact with others, etc., his account seems to be a truly return to some of Wittgenstein original ideas; specially on art criticism as something entirely dependent of art appreciation and of learning to “work on oneself” - in the sense that art appreciation requires a work on one’s own perception and beliefs. Finally, it is our opinion that this return to Wittgenstein through Carroll’s account evokes the idea that art education is a process of revisiting one’s own perceptions and beliefs by means of an encounter with history of art, culture, concrete contexts of language usage, etc.; things that represent the instance of a radical otherness.

title: EJA and Teaching Work in Freedom Deprivation Spaces

description: Abstract: This paper analyzes the emphasis of educational policies for Youth and Adult Education (EJA), focusing on the modality in Brazilian penal units. From this movement, relationships established with research in the field that deals with the work of teachers in spaces of deprivation and restriction of freedom. The production, with a qualitative approach, is the result of bibliographic studies and documentary analysis. The reflections presented allow us to understand aspects of educational guidelines and studies in the area, articulated to the consequences for teaching work, given clashes and consensus produced in the context of neoliberal reforms.

title: The Subjects of YAE in Youth and Adult Education Research

description: Abstract: This paper refers to the state of knowledge of scientific productions on subjects of YAE in Brazil. The research problem was: What are the main theoretical and methodological foundations present in the productions resulting from research in the field of Youth and Adult Education in Brazil that deal with student subjects? We used the following descriptors for data collection: subjects + YAE, identity +YAE, and sociability + YAE. The analysis of 13 articles showed the interdisciplinary nature of the studies, the predominance of qualitative research, and the theoretical diversity that underlies this field of investigation. Given the limited number of publications, we perceived the importance of exploring this area of research and knowledge production.

title: Respecting Aboriginal Parents’ Involvement in their Children’s Learning

description: Abstract: In Australia (and arguably in many other countries) parent involvement in their child’s learning is dominated by Western notions of learning, education, pedagogy and knowledge. We discuss the application of a critical anthropology of education angle to these dominant discourses and methodological resources that encourage us to be in the field, to take time, and to, with critical reflexivity, listen and learn. We describe how we worked to create an Aboriginal Guided approach and drew on Aboriginal Research Protocols to maintain a steady and sharp emphasis on our practice as researchers.

title: Replication data for: To Work or Not to Work? Child Development and Maternal Labor Supply

description: We estimate the effect of early child development on maternal labor force participation. Mothers of poorly developing children may remain at home to care for their children. Alternatively, mothers may enter the labor force to pay for additional educational and health resources. Which action dominates is the empirical question we answer in this paper. We control for the potential endogeneity of child development by using an instrumental variables approach, uniquely exploiting exogenous variation in child development associated with child handedness. We find that a one unit increase in poor child development decreases maternal labor force participation by approximately 10 percentage points. (JEL J13, J16, J22)

title: Mobility and segregation: analysis of occupational positions in Ciudad Bolivar in Bogotá

description: Abstract Recently, social segregation issues have gained attention in Latin American cities. Particularly in Bogotá, the literature sheds light on the socioeconomic implications of spatial inequalities. Theoretically, the concept of segregation embodies a multiple scope, which in turn, that allows identifying and examining phenomena occurring in urban contexts. There are different forms of segregation (residential, socio spatial, ethnic, etc.) and therefore, identifying one particular issue to focus on becomes relevant. The aim of this paper is to analyze socio spatial segregation in Bogotá from a labor perspective by drawing on data collected in the “Multi-purpose Survey 2017” document. The result found in the latter were correlated with those achieved on the fieldwork carried out during the phase 1 of the research project “Urban mobility and the context as citizenship builders” led by scholars from the Urban Management master program of the Universidad Piloto de Colombia. This study took place in El Paraíso neighborhood, located in the Ciudad Bolívar district in Bogotá.

title: Urban-rural imaginaries at the Salado neighborhood in Ibagué, Colombia

description: Abstract This article presents the study carried out in El Salado Special neighborhood of the city of Ibagué in Colombia, which identified how the forms of meaning of the inhabitants changes the territory. The territory is understood as a dynamic experiential fact and loaded with symbologies that come from the imaginary of the citizens. The research methodology was carried out from a qualitative approach based on a questionnaire-survey and semi-structured interviews, which were correlated from the identification of patterns and semantic fields. It was possible to find that what characterizes the territory in the neighborhood is that it has an urban-rural dynamic in which the changes generated by the urban growth of the neighborhood and the importance of the historical and heritage in the configuration of a tourist territory are problematized. with rural characteristics.
