Pozorište u obrazovanju i njegov uticaj na razvoj imaginacije kod dece
Authors: Stanisavljevic Katarina
Published: March 2023

Primenjeno pozorište u obrazovanju (Drama in Education), zbog prirode dramskih metoda koje obezbeđuju visok nivo angažovanja i aktivna iskustva učenja, prema mišljenju mnogih teoretičara pozitivno doprinosi razvoju dečje kreativnosti i imaginacije. Imaginacija predstavlja jedan od kognitivnih procesa koji omogućava anticipaciju budućih događaja kao i sposobnost stvaranja novih celina kombinovanjem različitih perspektiva, ideja i pojmova koji u takvom obliku ne postoje u ranijem iskustvu. Cilj ovog rada jeste da se teorijski ispitaju načini na koje primenjeno pozorište u obrazovanju, uključujući njegove participativne prakse i kolaboraciju, utiče na razvoj jedne od kognitivnih funkcija – imaginacije – tokom detinjstva. S obzirom na to da se imaginacija može posmatrati kao veoma fleksibilan opšti proces koji se razvija tokom života, a na čiji razvoj utiču istorija, sociologija i kultura, teorijske osnove pri proučavanju imaginacije i kreativnosti kod dece pružiće učenja sociokulturnih psihologa, Lava Vigotskog (Lev Semenovich Vygotsky), Vlada Glaveanua (Vlad P. Glăveanu) i Kejta Sojera (Keith Sawyer).
Kako bi se potvrdila pretpostavka da primenjeno dečje pozorište u obrazovanju, zahvaljujući participativnim praksama koje doprinose kolaboraciji i rekonceptualizaciji različitih perspektiva, pozitivno utiče na razvoj imaginacije, biće upotrebljen metod teorijske analize. Rad je namenjen stručnoj javnosti, vaspitačima i učiteljima, te pedagoškoj zajednici kojoj može poslužiti kao potencijalna osnova za razmišljanje o uticajima koje drama u obrazovanju može da ostvari kada je u pitanju kognitivni razvoj dece.

Published: March 2023

O rápido avanço da globalização e seus mais diversos impactos, em termos de mudanças na distribuição e organização produtiva e comercial global, aprofundamento e ampliação dos fluxos financeiros, de conhecimento e tecnologia têm sido objeto de análise de uma crescente gama de estudos. Diante disso, este trabalho busca avaliar os possíveis impactos da globalização sobre a inflação para um conjunto de países avançados, emergentes e em desenvolvimento, no período de 1996 a 2013. Para tanto, considera-se um conjunto de indicadores, conforme proposto por Dreher (2006) para mensurar a globalização e avaliar seus impactos na inflação. Utiliza-se a metodologia de dados em painel, através da estimação de modelos por efeitos fixos (MQO) ou por efeitos aleatórios (MQG) e painel dinâmico (GMM System). Os resultados encontrados apontam que a globalização, seja através de sua medida mais ampla, bem como através de suas dimensões econômica e social, tem efeitos negativos e significativos sobre a inflação, indicando, assim que, para a amostra em questão e o período analisado, um maior (menor) nível de globalização está associada a menores (maiores) taxas de inflação. Por outro lado, a dimensão política da globalização não apresentou significância estatística, não tendo, portanto, efeitos sobre a inflação.
Ultramafic-Hosted Ni-Cu-Co-(As) Mineralization from an Ancient Oceanic Transform Fault Zone in the Troodos Ophiolite, Cyprus: An Analogue for Ultramafic Sea-Floor Massive Sulfide Mineralization?
Authors: Martin Andrew J. , MacLeod Christopher J. , McFall Katie A. , McDonald Iain , Jamieson John W. , Cox Sophie
Published: March 2023

Accumulations of sulfide minerals that are enriched in Ni-Cu-Co-(As) occur as sea-floor massive sulfide (SMS) deposits associated with ultramafic rock types on the sea floor and in ophiolite terranes as Outokumpu-type mineralization. In this study we focus on similar mineralization at Lakxia tou Mavrou in the Limassol Forest Complex of Cyprus, which represents the on-land exposure of an oceanic transform fault zone preserved within the Troodos ophiolite. Mineralization here consists of massive lenses of pyrrhotite associated with veins of isocubanite, chalcopyrite, Co pentlandite, and chrome spinel hosted in serpentinized mantle peridotite. We reexamine the field context of mineral occurrences and use in situ mineral chemistry, element mapping, and sulfur isotope ratios (δ34S) to constrain metal sources and provide an updated paragenetic model for Lakxia tou Mavrou. Highly variable S/Se ratios (304–108,571), a depletion in platinum group elements relative to mantle values, and an average δ34S value of –3.7 ± 2.4‰ (1σ, n = 17) in sulfide minerals support a hybrid hydrothermal and magmatic origin for the mineralization. Metals at Lakxia tou Mavrou were sourced from both the serpentinization of peridotites and from crosscutting intrusions, with later intrusions into the already serpentinized mantle lithosphere host providing a heat source to drive prolonged hydrothermal circulation. The reexamination of the field context of mineralization shows that the Ni-Cu-Co-(As) mineralization at Lakxia tou Mavrou originally formed because of the fault-guided intrusion of hot primitive magma bodies into serpentinized shallow mantle lithosphere in the active domain of an ocean-floor transform fault zone. The mineralization was subsequently partially disrupted by structures related to emplacement of the Troodos ophiolite. We show that the relationship between serpentinization, magmatism, and hydrothermal circulation at Lakxia tou Mavrou can be used to understand the formation of ultramafic-hosted SMS deposits in transform fault and other ultramaficdominated slow- and ultraslow-spreading mid-ocean ridge settings.
‘I try to be true to myself but other people have to fit you into a box’: Exploring how voluntarily childfree women discursively negotiate their sense of self in a pronatalist society
Authors: Hutchinson Ruth
Published: March 2023

Women who have consciously remained free of having children, also known as voluntarily childfree (Blackstone, 2019), occupy liminal spaces created for them by dominant social discourses that valorise reproduction and vilify childfreedom (Gotlib, 2016). Reproductive desire is socially constructed as biologically innate (Franke, 2010) and pronatalist discourses construct voluntarily childfree (VC) women as making an ‘unnatural’ choice (Gillespie, 2003). This research aims to explore how socially constructed positions about voluntarily childfree women have impacted their sense of self. Feminist Relational Discourse Analysis (Thompson et al., 2018) was used to listen for contrapuntal voices within VC women’s negotiation of identities. Through semi-structured interviews with six women, three prominent discourses were heard: Negotiating Identity in a Pronatalist Society; Still Being a Woman Whilst Not Being a Mother; and Political Implications of Being Voluntarily Childfree. Contrapuntal voices heard within these discourses highlighted that VC women skilfully negotiate complex and conflicting subject positions to create space for their identities as women. The complex nature of VC women’s subjective experience of selfhood serves as a challenge to the homogenised view of women’s identity perpetuated by the patriarchal discourses prevalent in political structures of social policies, healthcare and workplace settings.

Abstract-Emotion recognition systems have a significant role in many areas including forensic application, teleconferencing, phone conversation and other areas. These emotions that are exhibited by the individuals can be sensitized through the facial expression and in remote conversations. These emotions can be figured out using the speech signals. These speech signals that are articulated from the voice can be generated and recorded. The recorded pattern using the features the emotions generated can be identified. Emotional recognition is a major research area in speech recognition. The features of the emotions will affect the recognition efficiency of the speech recognition systems. Several techniques are used in recognizing the emotions. This paper contributes towards a novel methodology based on Multi modal emotion recognition system using Skew Gaussian mixture model, the updated equations are derived from using EM Algorithm. The verbal communication signals are recorded into WAV format, which are used for research, collectively with the facial gestures. The emotions of both male and female are obtained using LPC, MFCC, and SDC. Keywords- Emotional recognition, Skew Gaussian mixure model, EM algorithm,LPC, MFCC and SDC.
Solving the Food-Water-Energy Nexus One Step at a Time: Modernizing Irrigated Agriculture in Hood River, Oregon
Authors: Fernandez-Guajardo Patricia , Weber Edward P. , Seales Lisa
Published: March 2023

Food, water, and energy resources are critical to human survival. They are also interdependent. In the world of traditional irrigated agriculture in the US West, especially in arid or semi-arid areas, the Food-Water-Energy Nexus is undergoing severe challenges, including population growth, significant water scarcity, growing demands for environmental and species protection, downward pressure on commodity pricing from globalization, increasing demand and higher costs for energy, and the challenge of climate change. This wicked problem of food, water, water rights, energy, farmers, fish/ecology, and climate change is threatening not only the ability to restore and preserve the stream flows necessary to meet ecological needs, but also the legally mandated flows to senior water users and the economic viability of working rural agricultural landscapes. A case study of the Farmer’s Irrigation District in Oregon illustrates how a growing number of Western US irrigation district are modernizing their irrigation systems, labeled here as the Integrated Hydro-Irrigation-Restoration Model, by tapping the power of rivers to fuel new low carbon “small” hydropower facilities and pressurize water deliveries, while simultaneously taking measures to save water, promote less fertilizer usage, increase instream flows, and improve environmental outcomes. The new model is necessarily more responsive to the policy demands emanating from policymakers and environmentalists seeking redress for all parts of the Food-Water-Energy wicked problem, from carbon emissions to more environmentally and economically sustainable farming systems/communities.

Technology-enhanced Smart City Learning: a Systematic Mapping of the Literature
Authors: Gianni Francesco , Divitini Monica
Published: March 2023

Smart cities are a popular and recognized research topic. In urban spaces, the learning factor is an important component for citizens and local communities. This paper presents a systematic mapping of the literature on smart city learning, with focus on how technology is used to enhance smart city learning. The goal is to map the state of the art and to identify gaps in current research that can prompt new research in this area. Articles were collected from various online databases and relevant journal publications, selected according to defined inclusion/exclusion criteria. Abstracts were coded based on a number of criteria, including e.g. learning goal, used technology, and theoretical approach. Following the coding process results were analyzed to identify themes. In the paper we shed light on the current understanding of smart city learning by (i) Identifying common scenarios and learning settings; (ii) publication patterns; (iii) technical features in the supporting technology; (iv) learning theories and approaches that are mostly used; and (v) adopted type of research and research methods. The mapping shows that the concept of smart city learning is growing in popularity, with increasing number of publications in this area in the last years. However, the field is rather fragmented, with very different understanding of the concept. Smart city learning is also emerging as a very complex form of learning, with different stakeholders, learning activities, and technological solutions combined in rich eco-systems. The mapping also points out two largely unexplored areas of technological support, namely the Internet of Things (IoT) and the use of city-related data.

Authors: Seo Jinsil Hwaryoung , Sungkajun Annie , Sanchez Tiffany , Suh Jinkyo
Published: March 2023

We present Touchology, a series of interactive plants that explore serenity and emotional attachment through meditative touch of plants with interactive audio-visualizations. Our approach focuses on creating various audio-visualizations for tactile interactions with living plants to enhance relationships betweeen the plants and users while evoking their empathy. Touchology was designed to offer a passive form of interaction. Our project offers a calming point of focus when needed. We particularly approached two populations (children with Autism and older adults in an elderly home) because it is known that both groups have limited access or have barriers to nature but they would still enjoy. Due to simple technical setups, the projects presented here can be placed anywhere at the ease of a user. Preliminary studies with target populations indicate that calming tangible interaction with plants evokes mindfulness in a similar way to gardening related experiences.

Published: March 2023

Since mobile devices, such as smartphones and tablets, have become ubiquitous in our daily lives, their use in the modern public classrooms is an ever increasing occurrence. In order to meet the demands of the rising technology needs, teachers must be well versed in the pedagogical and curriculum uses of mobile devices. However, general and special education pre-service teacher education programs rarely provide the knowledge, skills and practice that are necessary to integrate mobile technology in ways that will affect positive changes in student learning. The purpose of this systematic literature review was to determine the prevalance of and current trends in mobile technology training in teacher preparation programs, especially as it applies to pre-service special education teachers. Results of the review revelaed a paucity of research on the topic in both special and general education.

Published: March 2023

This paper presents a model of relationship between personality traits and students’ roles, based on learning theories, to improve the formation of high performance groups. It has two main contributions: first, a process to model collaborative learning roles based on personality traits; second, an ontological structure to support group formation. Regarding the proposed process, we defined four steps for an effective group formation: (i) determine personality traits characteristics; (ii) identify which personality traits characteristics may affect negatively students’ behavior in educational collaborative settings; (iii) define new collaborative learning roles given the personality traits; and (iv) establish learning strategies to ensure students’ educational benefits. Additionally, we represented those new roles in a collaborative ontological structure. Finally, we performed a case study, which showed evidences that unsociable characteristic may negatively influence students’ behavior, and therefore, it should be considered to design CSCL scenarios and personalized systems to form high performance groups.

Tip pruning for synchronized vegetative growth and controlling alternate bearing in mango (Mangifera indica)
Authors: BARMAN P , MISHRA D
Published: March 2023

Alternate bearing in many mango (Mangifera indica L.) cultivars including Dashehari is one of the main hurdles in maximising fruit production thus causing a major threat to the expansion of mango industry. Therefore an experiment was conducted for four consecutive years on 10-12 years mango cv. Dashehari spaced at 7.5 m x 7.5 m to induce synchronous vegetative growth to get same physiological stage of shoots for regular uniform flowering and fruiting in mango cv. Dashehari. For this purpose, whole tree was tip pruned just below first node after crop harvest and thereafter drenched with paclobutrazol @ 3.2 ml/m canopy diameter during September. Tip pruning was also performed in October to study its effect on panicle emergence bypassing vegetative flushing. The result exhibited significant influence of post-harvest pruning cum paclobutrazol application on uniform flowering, fruit yield and quality parameters while October pruning had positive effects on light availability below tree canopy, however increased vegetative growth at the expense of flowering and fruiting. Thus whole tree tip pruning after harvest of off year fruits followed by soil drenching with paclobutrazol, a month prior to flower bud differentiation, could be adopted for regulating flowering and fruiting during off year.

Published: March 2023

Growing vegetable crops in Mewat poses a serious challenge due to its agro-climatology and edaphic characteristics. The main occupation of inhabitants in Mewat is agriculture and allied agro-based activities. Seeing the importance of area, an attempt was made to introduce vegetables cultivation at commercial level to increase the income of farmers and improve their livelihood condition. The introduction of crops, like tomato, brinjal and bottlegourd in Mewat has enhanced the farmer's income significantly and it has attained commercial status. Though income and yield enhancement was recoded at every farmer's level but some farmers who were mainly landless and practicing vegetable farming on rented land could increase their profit to a record level in a period of 3 years from 2011 to 2013. On an average basis in tomato, brinjal and bottlegourd, the yield increased up to 58%, 44% and 82% and profitability up to 49%, 48% and 55% respectively. If other interventions like, drip irrigation, Integrated Pest and Nutrient Management (IPM and INM), polyhouse cultivation, off-season nursery and vegetable production, efficient post-harvest handling with cool chain facilities, value addition and processing, contract farming etc. are added, the income and profitability may increase many folds. On over all basis, bottlegourd variety Pusa Naveen, brinjal variety Pusa Uttam and tomato hybrids Heemsohna and US 2853 were most demanding and fetched higher prices due to their high yield and fruit quality attributes. Therefore, it was proved that vegetable production is the emerging sector in agricultural diversification that would augment income of smallholders and generate employment opportunities in rural areas.
“El Ñandú” en el cielo: etnoastronomía de gringos, criollos e indígenas y las representaciones celestes de Rhea americana en el sur del Chaco argentino
Authors: Mudrik Armando
Published: March 2023

In this paper, we take a cultural astronomy approach to study the astronomical representations of the Greater Rhea (Rhea americana) among Indians and European immigrants and their descendants settled in the agricultural colonies in the northern area of the province of Santa Fe, in the southern Argentinean Chaco. Through the dialogue between our ethnographic field research among these immigrants and their descendants and the results of previous studies about two Guaycuru societies (Toba and Mocovi Indians), we explore the cultural role and the different astronomical representations of the Greater Rhea. We expose various relationships between these representations and different aspects of the social life of the studied groups. Then, analyzing some of these relationships, we show the logic used in these associations. In particular, we show that these cultural groups have shared astronomical representations of the Greater Rhea, and also knowledge about its biological cycle and its behaviour in relation with humans. This research intends to add to the interpretation of how the European colonists and their descendants interacted with their new natural and socio-cultural environment, and also to the understanding of the role of the Greater Rhea in the processes of ethnic interaction in the Chaco Region of Argentina.

Authors: Borghi Carlos E. , Hernández Jorge , Campos Claudia M.
Published: March 2023

Rhea tarapacensis is a threatened species ecologically extinct in part of its distribution range. It is one of the species most used in traditional medicine in the vicinity of the San Guillermo Biosphere Reserve (San Juan, Argentina), and its recognition by residents, the common names it receives and other historical and current uses still remain to be assessed. This study was carried out at four locations close to the reserve. A total of 171 semi-structured interviews were conducted with residents of both sexes, older than age 15, who have different activities and educational levels. Ninety five percent of the people recognized Rhea tarapacensis, which is locally called Avestruz, Chure, Churi or Ñandú. Contributors mentioned a strong historical use of its meat and feathers, and a lower but still important current use. Men, people between 31–45 years old and the residents of Tudcum were the ones who mentioned more historical and current uses of this species. Sixty percent of men claimed to have sighted Rhea tarapacensis over the past year. Considering the uses for obtaining meat and feathers and the recognized medicinal uses, the hunting pressure on Rhea tarapacensis could not be properly considered in the current evaluation of its conservation status. This makes necessary a continuous monitoring of the species in the region, including the protected area, accompanied by the implementation of programs of education and sustainable use directed to the residents, targeted at its conservation.
Primeros registros de nidificación del Vencejo de Tormenta (Chaetura meridionalis) en Argentina
Authors: Sferco Guillermo
Published: March 2023

I report the first breeding records of the Ashy-tailed Swift (Chaetura meridionalis) in Argentina. Between December 3 and 6, 2015, two nests of this species were found in a Chaco forest in central Argentina, located in holes of quebracho blanco. One of the nests contained three nestlings and the other five. As the species is present during the breeding season in central and northern Argentina, it was supposed to nest in the country but until now there were no specific records.
Conteo oportunista de individuos leucísticos de Carancho (Caracara plancus) dentro del Parque Patagonia Austral (Chubut, Argentina)
Authors: Agüero María Laura , Berrier Hebe E. , Massabie Pedro J.
Published: March 2023

In this work we report the first partial survey of leucistic individuals of the Southern Crested-Caracara (Caracara plancus) in the Interjurisdictional Marine Park of Patagonia Austral, Chubut, Argentina. Between September 2016 and January 2017, 1325 km were surveyed within the park. During the survey, we sighted a group of 66 individuals of the Southern Crested-Caracara, approximately 2 km from the coast of Bahía Melo, associated with the remains of guanaco hunting, of which 36 were lightly coloured (5 of intermediate coloration and 31 leucistic). These records increase the information available about this particular population with chromatic aberrations.
Revisión de los estudios científicos sobre ornitología urbana de La Habana, Cuba

Published: March 2023

We analyze the level of knowledge of urban ornithology in Havana, Cuba, based on the compilation of papers published in scientific journals. We identified a total of 49 studies published between 1878 and 2016, mostly in local or regional journals (76%). Species lists and ecological studies were the most frequent research categories, while conservation studies were very scarce. The studies addressed basic aspects of knowledge and have been sporadic over the years. More than half were carried out during the 1980s and 1990s, period in which the first ecological studies that prevail until now appeared. Green spaces were the type of urban habitat with the highest number of species included in the compiled articles. Research conducted in sites located in the municipalities with the lowest population density predominated. We provide a list of 172 bird species for Havana from the compiled information. Urban ornithology in Havana is still a young discipline in number, impact and depth of research. Future studies should relate different biological, social, cultural and economic research lines that allow the development of effective management and conservation strategies for the avifauna within the city.

La conservación de las aves en la era de la genómica
Authors: Mahler Bettina
Published: March 2023

Next-generation sequencing techniques have changed the way of obtaining genetic data for studies in avian conservation, from the analysis of a few loci located in a small portion of the genome to obtaining information from hundreds to thousands of loci distributed all over the genome. A larger number of markers provides more information for phylogenetic, introgression and population structure studies, and allows a better estimation of demographic parameters. Measures such as heterozygosity, parentage, paternity and inbreeding can be estimated more accurately. In addition, one of the greatest contributions of genomic studies is the identification of both adaptive and neutral variation. In this paper I briefly explain the methodological basis of next-generation sequencing and show examples of the use of genomic data in conservation studies in birds.
Replacement sequence for the flight feathers of the Blue-black Grassquit (Volatinia jacarina) and the Gray Seedeater (Sporophila intermedia)
Authors: Moreno-Palacios Miguel , Losada-Prado Sergio , Echeverry-Gálvis María Ángela
Published: March 2023

Knowing the order and way in which the flight feather replacement process takes place is fundamental to elucidate the specific strategies adopted by different species in relation to the environmental and ecological pressures to which they are subjected. This information is not available for the majority of the Neotropical species, which hinders understanding this process in functional or evolutionary contexts. Seeking to determine the replacement sequence of flight feathers during a complete molt in the Blue-black Grassquit (Volatinia jacarina) and the Gray Seedeater (Sporophila intermedia), captures were made with mist nets at the Centro Universitario Regional del Norte in Universidad del Tolima (Armero-Guayabal, Tolima, Colombia). A standardized protocol was followed for the description and analysis of the molt patterns of flight feathers. In general, the replacement pattern of flight feathers proceeds according to the basic sequence observed in other passerines. Primary remiges in both species constituted a single molt series, as the rectrices. Secondary remiges represent two molt series, which may be related to aerodynamic or energetic necessities. Given the high energetic demands of molting, it might be possible that similar species may evolve different mechanisms to carry on this event, supporting a high phenotypical plasticity among and within lineages, which may be associated with a fast adaptation process.
Seasonal distribution of the Striated Heron (Butorides striata) in southern South America: evidence for partial migration
Authors: Hayes Floyd E. , Hayes Brett D. , Lecourt Peter
Published: March 2023

The nominate subspecies of the Striated Heron (Butorides striata striata) inhabits most of South America. Previous authors suggested that the southernmost populations are partially migratory based on anecdotal evidence. An analysis of 9352 eBird records from south of 20°S reveals that the proportion of Striated Heron records during the austral winter months (June–August) decreases south of 24°S. Breeding occurs as far south as 37°S, whereas individuals have wintered as far south as 39°S. The seasonal distribution data strongly suggest that populations south of 24°S are partially migratory, with most individuals departing during the winter period in southern Paraguay, southeastern Brazil, Uruguay, and most of Argentina. Given the absence of band recovery, geolocator recovery, or satellite tracking data, it is unknown how far north the southernmost populations migrate, but heat maps of 35304 eBird records in South America suggest most individuals winter in eastern Bolivia and central Brazil. Further studies are needed to elucidate the migratory pathways and destinations of migrant individuals of the Striated Heron.
Reproducción y alimentación del Águila Mora (Geranoaetus melanoleucus) en el noroeste de Chubut, Argentina
Authors: Villegas-Davies Vanesa , Floria Pía , Casaux Ricardo
Published: March 2023

In this work we make the first contribution on the breeding and feeding ecology of the Black-chested Buzzard-Eagle (Geranoaetus melanoleucus) in Chubut Province, Argentina. During the 2012-2013 breeding season three nests were located; we recorded the chronology and reproductive parameters, and counted and identified preys. The average clutch size observed was 2.3 eggs per nest. The hatching success was 100% for two of the nests and 50% for the other, the breeding success was 100% in the three nests and the average number of fledglings of 2 per pair. The permanence of the nestlings in the nest fluctuated between 9–12 weeks, a period longer than that described in other studies. The European Hare (Lepus europaeus) was the main prey and the recorded food spectrum was similar to that of previous studies.

Published: March 2023

We studied the abundance and habitat use of Crax fasciolata using camera-traps in different types of forests in the Humid Chaco of Paraguay. We obtained 114 records with a total sampling effort of 996 camera-days, most of them from one and two individuals, with a maximum of five individuals. The highest number of records was obtained in the riparian forest, with a capture success of 20%, and during the spring, with a capture success of 22%. The species showed diurnal activity with most records during the morning. We recommend to deepen these investigations analyzing not only the type of forest but also the time of the year in which the species is recorded in each habitat.
