PRE-SERVICE TEACHING PROGRAM FOR EDUCATING STUDENT- TEACHERS IN MANAGING THEIR CLASS
Authors: Sulistyowati Titis , Kurniati Diah
Published: February 2019

This article presents the finding of a study that investigate pre-service English teacher in managing the class when they were teaching in teaching practice program or Pre-Service Teaching Program.  Teaching in a real class is a new experience for the students of Muria Kudus University; however they need to adjust themselves to the teaching environment. They need to prepare some educational knowledge like; classroom management, educational psychology, curriculum development, teaching method etc, in order to be able to organize the lesson well and achieve maximum result. The key of a successful learning is depended on the way teacher organizing the class. In other word the key of a successful language teaching is classroom management.  However each class has different characteristics, so a teacher needs to prepare himself to the students’ learning style.  Maintaining discipline and organizing students can be very frustrating for the student-teachers because they do not only need well understanding about classroom management but they also need to control their performance. The students- teacher or teacher candidates need guidance either from the school teachers or their lecturers; therefore it is also very important to observe their activities in the class to know the improvements which have been done by the teacher.

While secondary data sources obtained through reference with the study of cultural acculturation in society. Techniques of collecting data through interviews with informants, observations on campus sera student boarding environment and documentation. The validity of data is done by using source triangulation technique and method. Data were analyzed using Miles and Huberman model which include data collection, data reduction, data presentation and conclusion. Cultural acculturation is a social process that students pass through on campus as they associate with their friends. This process occurs because students have different cultures from each other. The process of meeting the two different cultures, but they are able to co-exist without eliminating the elements of each. They associate with college friends without distinguishing the origin of the region, tribe, religion and race. It can be seen through the activities undertaken on campus, such as student activities, activities in order to meet the tasks of college and so forth. In social intercourse they face obstacles, including language, customs and cultural differences

This paper presents the methodology and results of the research aimed to identify the current and potential functions of open public spaces in post-Soviet modernist urban districts in the context of sustainable urban development. The research is based on the sociotope mapping methodology facilitating the identification and interpretation of functional characteristics of urban open public spaces. The data for this research has been collected in three selected pilot multi-apartment modernistic districts of Kaunas city (Lithuania) using two sociological research tools – site observation protocols and user questionnaires. The research results show the need for actors involved in planning and (re)development of modernistic districts to incorporate a larger diversity of space elements enabling different local area users (individuals, families, organizations) to use and experience more natural, social, economic and other values available locally at different time (year, day) periods.

Published: February 2019

For the period from the 1st of May to the 30th of October 2014, the water balance for Scots pine, Norway spruce, Pedunculate oak and European beech seedlings in a plantation setting was analysed. The experiment was conducted at the container nursery in the Rudy Raciborskie Forest District, Poland. Water was supplied by natural rainfall as well as a by small-droplet irrigation system and two automatic weather stations combined with 32 rain collectors were used to monitor rainfall throughout this research. Rain gauges were located 25 cm above the metal pallets and 10 cm below the nursery containers. An average of 987 mm∙m−2of water reached the plantation, of which 53% were provided by the irrigation system. Most water was supplied to the oak field, whereas least was given to the spruce plantations and the irrigation water amounted to 535 liters and 422 liters per square meter, respectively. The amount of water percolating through the substrate was approximately 50–65%, depending on the tree species. An average sum of evapotranspiration at the container nursery was estimated to amount to 520 mm∙m−2during the growth season leading to a total water balance of +463 mm.
Cricetidae (Rodentia, Mammalia) from the early Miocene site of els Casots (Vallès-Penedès Basin, Catalonia)
Authors: Jovells-Vaqué Sílvia , Ginestí Montserrrat , Casanovas-Vilar Isaac
Published: February 2019

Els Casots is an extremely rich early Miocene site located in the Vallès-Penedès Basin (Catalonia, Spain) that has provided both micro- and macrovertebrates. However, the small mammals have been poorly studied. In this work we describe the cricetid fauna from els Casots and provide further insights into the chronology of the site. The cricetids are very common and include the species Megacricetodon primitivus and Democricetodon hispanicus. A second, larger-sized Democricetodon species is also represented by just one molar. The presence of M. primitivus together with the eomyid Ligerimys ellipticus indicates a correlation to zone MN 4 and to the local zone C of the Calatayud-Montalbán Basin (Aragón, east-central Spain), the type area of the Aragonian mammal age. This is further supported by the presence of two different Democricetodon species. A correlation to the local subzones of that area is attempted, but unfortunately the cricetid succession is not the same in both basins. However, the fact that L. ellipticus is the only eomyid species present at els Casots would indicate that this site is somewhat younger than other MN 4 localities from the Vallès-Penedès, where this species coexists with its ancestor Ligerimys florancei.
Early Late Miocene Murine Rodents from the Upper Part of the Nagri Formation, Siwalik Group, Pakistan, with a new fossil calibration point for the Tribe Apodemurini (Apodemus/Tokudaia)
Authors: Kimura Yuri , Flynn Lawrence J. , Jacobs Louis L.
Published: February 2019

The early late Miocene is an interval of increased diversification for murine rodents. Whereas the genus Progonomys became widespread throughout Eurasia by 10 Ma, it appears from the known paleontological record that southern Asia is the arena of evolution and diversification at the base of the Murinae. The Siwalik fossil record of the Potwar Plateau in northern Pakistan preserves fossil evidence relevant to unraveling this history. Murine rodents are recorded there throughout the middle Miocene, and diversification began in Siwalik assemblages before 11 Ma. The well-established Progonomys and Karnimata lineages were already present between 11 and 10 Ma, and these represent extant murine crown groups. Here we document diversity in Siwalik murines dating to 10.5 to 10.1 Ma, and clarify their recognition by naming a new species of Karnimata and referring specimens of Progonomys from this interval to P. hussaini. In addition, we define at least two other uncommon murine species that coexist with them. One of these is an early record of Parapodemus, a fossil genus of Tribe Apodemurini, which constitutes a calibration point for the Apodemus/Tokudaia split. Together, these fossil taxa provide further evidence bearing on the major split among murines leading to the clades Murini and Arvicanthini.
The new Early Miocene bat records from the Molasse sites of South Germany
Authors: Rosina Valentina V. , Rummel Michael
Published: February 2019

Fossil bats are described from deposits of the Upper Freshwater Molasse of the Forsthart and Rembach sites in East Bavaria of South Germany (MN 4). The material comprises 13 fragments, representing at least six different species, all belonging to Vespertilionidae. A fossil form from Rembach, close to the Oriental clade of Hesperoptenus, represents the first and oldest fossil record of this clade in Europe. The assignment of bat records to extant Oriental clades Hesperoptenus and Submyotodon in Rembach, as well as different forms of Miostrellus in Forsthart indicate considerable diversity in Early Miocene vespertilionid bats, and have exciting palaeobiogeographic implications. Fossils are discussed in regards to taxonomic, stratigraphic and palaeoecological significance.

Published: February 2019

The 2017 field survey of the Ashawq Formation, Dhofar, Oman, resulted in the collection of large mammal remains, most of which belong to Afrotheria, but with one artiodactyl lineage indicating the possibility of dispersal links with Eurasia. The new fossil remains increase our knowledge about the dental anatomy of the endemic lophodont proboscidean genus Omanitherium, revealing, in particular, that it possessed two pairs of lower incisors. For the first time, a palaeomastodont is recorded from the Arabian Peninsula. Additional remains of Arsinoitherium, a hyracoid and an anthracothere from the formation are described.
Pavlovian hunters on the margin – archaeozoological analysis of the animal remains discovered at the Pavlov II site (1966 – 67 excavations)
Authors: Wilczyński Jarosław , Wojtal Piotr , Svoboda Jiří
Published: February 2019

Our archaeozoological studies concerns animal remains discovered during fieldworks led by B. Klíma in 1966 – 1967. The study does not include a few bone tools and personal ornaments made from animal teeth. There were analysed 968 remains of different animal species. Among the mammals, the most numerous are bones and teeth of mammoth, horse, wolf, and reindeer. Other taxa are less numerous, but we point out presence of cave lion bones. The quantity of animal remains discovered at Pavlov II is much lower in comparison with other Pavlovian sites from Pavlov-Dolní Věstonice area. The localization of archeological trench, on the periphery/margin of a larger Pavlovian site, most likely had effect on not large number osteological finds. Nevertheless, our study confirms the importance different Pleistocene species in the everyday life of Gravettian hunters-gatherers. They relied not only on herbivores, but also carnivores, such as wolves, wolverines, bears and cave lions.
Anterior premolar variability in Pleistocene cave and brown bears and its significance in species determination
Authors: Pacher Martina
Published: February 2019

The current study deals with the anterior premolar pattern in the cave and brown bear lineage, and its significance in species determination. The occurrence of single premolars and its combinations in skulls and mandibles is recorded for various chronological and regional groups.

Both lineages stay more “conservative” in the upper than in the lower dentition, but show contrasting reduction tendencies. Brown bears tend to retain the first premolar, while in the cave bear lineage, third premolars prevail.

Exclusively diagnostic for brown bears is the occurrence of a single P1, as well as a complete dentition in skulls. With caution, the combination of P1 and P3 is characteristic for the Deninger bear/cave bear lineage. This pattern was not observed in the current brown bear sample, but has been mentioned in literature. In mandibles, evidence of a single p1 (and its combinations) and a complete dentition is exclusively found in brown bears.

A single lower p3 is diagnostic for Deninger bears in completely preserved diastema. The absence of all three anterior premolars as typical for the cave bear lineage is occasionally reported for brown bears in literature, but was not observed in the studied material. Other premolar combinations stay scarce in both lineages, and may partly be influenced by early or pathological tooth loss.

Brown bears reveal no evolutionary trend in premolar reduction. All possible patterns and a similar frequency of complete dentition is found in modern and fossil representatives.

No evidence was found for high variability in the premolar pattern of U. deningeri, as is suggested in literature. The already moderate presence of anterior premolars declines further in Late Pleistocene cave bears. Nonetheless, already the bears of the Cromerian Forest-Bed lack all anterior premolars in mandibles, and hence imply partly evolutionary tendencies in the cave bear lineage, but also populational differences in the occurrence of premolars anterior the P4/p4.

Authors: Kerekes-Máthé Bernadette , Dudás Csaba , Csergő Nóra , Mártha Krisztina
Published: February 2019

Background: Measurement-based studies are prone to measurement errors, which occur at the same operator or between different operators during repeated measurements of the same sample.

Aim of the study: To assess the inter-operator reliability of morphometric measurements using a bidimensional image analysis method.

Material and methods: Eight study models have been selected, images of teeth and models were taken from vestibular and occlusal view. The following parameters were measured individually by three, previously trained operators: mesio-distal, occluso-gingival, and vestibulo-oral dimensions, vestibular and occlusal area, depth of palatal arch, arch breadth, arch circumference, and arch length. Intraclass correlation coefficients were calculated for each measurement.

Results: The reliability of the measurements showed high degrees, all values being higher than 0.8.

Conclusions: Dental morphometric measurements done by 2D image analysis can be performed by multiple operators with an excellent reliability.

Authors: Śmiech Anna , Łopuszyński Wojciech , Ślaska Brygida , Bulak Kamila , Jasik Agnieszka
Published: February 2019

Introduction: Breed predisposition to cutaneous mast cell tumours (MCT) in a population of dogs in Poland affected by various skin tumours was assessed, and the distribution of MCT characteristics such as histological grading, sex, age, and location, in predisposed breeds was evaluated.

Material and Methods: The retrospective epidemiological study included 550 dogs affected by cutaneous MCTs with a reference group of 2,557 dogs diagnosed with other skin tumours.

Results: A univariable logistic regression analysis was performed to determine the odds ratios (ORs) with 95% confidence intervals. The risk of high-grade MCTs was the highest for Shar-Peis (OR: 26.394) and American Staffordshire Terriers (OR: 2.897). Boxers (OR: 6.619), Labrador Retrievers (OR: 2.630), French Bulldogs (OR: 2.050), Golden Retrievers (OR: 1.949), and American Staffordshire Terriers (OR: 2.592) were mainly affected by low-grade MCTs. The high risk of MCT was calculated to be at the age of 4–6 years for Labrador Retrievers (OR: 2.686) and 7–10 years for Boxers (OR: 2.956) and French Bulldogs (OR: 9.429). MCTs were significantly more often located on the trunk in French Bulldogs (OR: 4.680), American Staffordshire Terriers (OR: 2.520), and Labrador Retrievers (OR: 1.948). There was no statistically significant correlation between gender and the occurrence of MCTs in the breeds.

Conclusions: The breed-predicated differences in the clinical course of MCTs suggest a genetic background for the tumours.

Published: February 2019

Introduction: Peroxiredoxin 6 (Prdx6) is a bifunctional protein with glutathione peroxidase activity and phospholipase A2 activity. Previous studies have shown a significant positive correlation between the intracellular survival ability of Brucella and Prdx6. Here, the Prdx6 enzyme with a single activity was constructed to facilitate study of the relationship between the single function of Prdx6 and Brucella infection.

Material and Methods: The target open reading frame (ORF) DNAs of Prdx6 with a single active centre were prepared using gene splicing by overlap extension PCR (SOE-PCR), and the recombinant eukaryotic expression plasmids inserted by Prdx6 with the single activity centre were constructed and transfected into murine Raw264.7 macrophages. The glutathione peroxidase activity and phospholipase A2 activity of the constructed Prdx6 were examined.

Results: The core centres (Ser32 and Cys47) of Prdx6 were successfully mutated by changing the 94th nucleotide from T to G and the 140th nucleotide from G to C in the two enzyme activity cores, respectively. The constructed recombinant plasmids of Prdx6 with the single active centre were transfected into murine macrophages showing the expected single functional enzyme activity, which MJ33 or mercaptosuccinate inhibitors were able to inhibit.

Conclusion: The constructed mutants of Prdx6 with the single activity cores will be a benefit to further study of the biological function of Prdx6 with different enzyme activity.

The study investigated the challenges of marketing Abakaliki rice with interest in establishing the profitability and socio-economic characteristics of the marketer of the product. Mixed-method research approach consisting of the application of questionnaires and interview was used. It was conducted in three major markets located at Onu Ebonyi, Abakpa and Kpirikpiri in Ebonyi state, Nigeria. The population of the study was 120 marketers randomly selected using simple random sampling technique and proportional to the size of the market. Data was analysed using descriptive statistics. The results shows that women dominate the trade as 62% of Abakaliki rice marketers are women. Challenges of institutional, transportation facilities capital and credit facility constrained the growth of the business. Cost benefit analysis also shows that marketing of Abakaliki rice is profitable as N192, 740 only was the net profit at the end of the trading period. The study concludes by recommending formation of cooperative societies to enhance accessibility of start-up capital while governments at various levels should develop marketing policies that increase the marketing network of Abakaliki rice.

Authors: de la Torre Genoveva Millán Vázquez , Navajas-Romero Virginia , Rojas Ricardo Hernández
Published: February 2019

Although the immigrant population in Spain has decreased due to the economic crisis of the past five years, few studies have analysed this group. The objective of this research has been to profile the immigrant who decides to start a business in Spain. In order to learn about the probability of immigrant workers being entrepreneurs as a function of their socio-demographic characteristics, data from the Spanish National Institute of Statistics from 2005 to 2016 have been analysed and fieldwork carried out during August and September 2016 on immigrants who are self-employed. The results show a lower rate of entrepreneurship in the immigrant population vis-a-vis the native population and the fact that creating their own business begins at an earlier age for immigrants when compared to the national average.

Published: February 2019

This research tried to identify similarities and differences in motives between male urban entrepreneurs from Mexico and Morocco. The Mexican sample of 192 respondents was drawn from Chambers of Commerce listings in Guadalajara and Monterrey. The Moroccan sample of 222 respondents came from the Fès-Meknès region. In both countries a majority of entrepreneurs went into business by necessity and pursued monetary goals in order to secure their financial future for their families and for themselves. Larger cohorts of younger entrepreneurs were present in Mexico, where female spouses tended to be more often involved in their husband’s business and contributing more to family income, as compared to Morocco. In Mexico, a larger proportion of entrepreneurs were also expressing a very strong interest for intrinsic goals involving self-actualization, meeting challenges, while Moroccan respondents were more in search for autonomy and independence besides pursuing extrinsic or financial goals. Results generally confirm results obtained elsewhere in Africa and Latin America.
Preparation of nanosized NaA zeolite and its surface modification by KH-550
Authors: Hou Jin , Jiang Qiwang
Published: February 2019

Nanosized NaA zeolite was successfully synthesized by hydrothermal method using tetraethyl orthosilicate (TEOS) and aluminum isopropoxide (AIP) as the main raw materials. The surface modification of NaA zeolite was carried out by silane coupling agent 3-aminopropyltriethoxysilane (KH-550). The effects of silane coupling agent dosage, reaction temperature, reaction time, hydrolysis time and pH value on grafting rate of NaA zeolite were investigated in detail. The zeolites were characterized by XRD, SEM-EDS, FT-IR and TG-DTA. The results showed that the surface of NaA zeolite was modified successfully by KH-550. The optimal modification conditions obtained were as follows: the dosage of coupling agent in 95 % ethanol – 1.6 %, reaction temperature − 70 °C, reaction time – 2 h, hydrolysis time – 20 min, and pH value – 3.5. Under these conditions, the grafting rate of modified NaA zeolite was 3.95 %.
Data Visualization in Scandinavian Newsrooms: Emerging Trends in Journalistic Visualization Practices
Authors: Engebretsen Martin , Kennedy Helen , Weber Wibke
Published: February 2019

The visualization of numeric data is becoming an important element in journalism. In this article, we present an interview study investigating data visualization practices in Scandinavian newsrooms. Editorial leaders, data journalists, developers and graphic designers in 10 major news organizations in Norway, Sweden and Denmark provide information for the study on a range of issues concerning visualization practices and experiences. The emergence of multi-skilled specialist groups as well as innovation in technology and the ‘mobile first mantra’ are identified as important factors in the fast-developing practices of journalistic data visualization. Elements of tension and negotiation are revealed for issues concerning the role and effect of complex exploratory data visualizations and concerning the role of ordinary journalists in the production of charts and graphs.
Please Like, Comment and Share our Campaign!: How Social Media Managers for Danish Political Parties Perceive User-Generated Content
Authors: Farkas Johan , Schwartz Sander Andreas
Published: February 2019

Based on 18 qualitative interviews, this article explores how the social media managers for the nine parties in the Danish parliament articulate the role of social media during the 2015 national elections. The article finds that the interviewees emphasise Facebook as an important means for one-way political communication and the monitoring of public opinion. The majority of the interviewees articulate a sense of responsibility for facilitating public debate on Facebook through the moderation of user-generated content and/or interactions with users. Yet the social media managers do not systematically analyse political input from social media users, nor do they see Facebook and Twitter as viable means of citizen influence on political decision-making. This is explained by a perceived lack of voter representativeness among Facebook users, fear of appearing politically imprudent and scepticism towards social media’s participatory potential.
Local Newspapers, Facebook and Local Civic Engagement: A Study of Media Use in Two Norwegian Communities
Authors: Lie Malene Paulsen
Published: February 2019

The European decline in newspaper circulation has fuelled debates on the consequences for civic engagement and democratic participation. Based on a qualitative interview study with 29 inhabitants of two Norwegian communities, this article examines the importance of the local press and of Facebook in the civic actions of ordinary citizens. Overall, the study suggests that both media are important and enable citizens’ involvement in collective problem-solving. However, their importance lies on different levels, as the two media play complementary roles: Whilst Facebook’s networking possibilities enable new forms of online volunteering and mobilisation, the local press constitutes a shared public sphere in which interviewees can gather information and create awareness of local happenings, politics and volunteering.
Jewel in the Crown: The Nobel Banquet Broadcast as Co-Construction
Authors: Ganetz Hillevi
Published: February 2019

This study explores the aims of the Nobel Banquet broadcast, produced by the Swedish public service company SVT and the Nobel Foundation. The study suggests that the programme can be viewed as a co-construction of science and media, and that the Nobel Foundation has three primary purposes: 1) to teach the audience about science; 2) to honour the laureates; and 3) to maintain and increase the status of the Nobel prize. SVT, for their part, has two main purposes: 1) to teach their audience about science, and 2) to entertain. The aims of the Nobel Foundation and SVT may seem disparate, but they are interrelated. At the same time, the subtleties between the entities create a tension that develops through mutual negotiations. The study ends with a discussion of two unexpected findings: 1) the shared, yet essentially differently-grounded aims of both parties to inform about science, and 2) the fact that their scientific content has increased in both absolute and relative terms over the years, a finding that questions notions of a continuous mediatisation of social institutions.
Educating Land Forces’ Leaders to Think from JIIM Perspective
Authors: Tudorache Paul , Ispas Lucian
Published: February 2019

Nowadays, the military forces’ operational environment is shaped by dynamic changes that give its most representative characteristics such as volatility, uncertainty, complexity and ambiguity (VUCA). Based on this and taking into consideration the tendency of NATO to use more prominently its multinational military structures, we are obligated to adapt our way of teaching and training if we want to be effective in the process of educating the next leaders for future military environments. In other words, during the classes, also in the field, we should try to educate and train our cadets, at least, to think from a joint, interagency, intergovernmental and multinational (JIIM) perspective when conducting military actions, even at a small tactical level, such as the platoon.
Could The Insolvency Risk for Companies Traded on Bucharest Stock Exchange have been Identified? A Case Study Using the Altman Model
Authors: Vasiu Diana Elena
Published: February 2019

Insolvency represents the state of the debtor’s patrimony characterized by insufficient funds available for the payment of certain, liquid and due debts. It may occur even in case of strong companies, for example, in case of listed companies, generating loses for investors. In economic theory, a series of insolvency risk prediction models were developed, based on the method of scores, the most known and used being the Altman model. At the present moment, five companies, traded at Bucharest Stock Exchange are insolvent. The aim of this paper is to establish if the Altman model can successfully be used for Romanian traded companies, to determine the risk of insolvency.

In recent years, a significant number of epidemiological variations have been observed for fungal infections. In immunocompromised patients, Candida albicans is crucially involved in invasive infections, mostly originating in respiratory tract colonization. The global rise in candidiasis has led researchers to investigate possible correlations between fungal strains virulence profiles and their pathogenic potential, among the most investigated genes being those involved in adherence and biofilm development. In this study, we established the adherence gene profiles of C. albicans strains isolated from respiratory tract secretions in patients hospitalized for cardiovascular diseases and correlated them with the ability of the respective strains to colonize the epithelial cells and form biofilms on the inert substratum. The strains isolated from the lower respiratory tract exhibited the highest adherence capacity and were intensive biofilm producers. The SAP9, ALS3, ALS5, and ALS6 genes were the most frequently detected. There was a significant association between the presence of ALS 3 gene and the cellular substrate colonizing potential of the harboring strains. We also found that the strains expressing SAP9 were more virulent in the phenotypic assays. Detecting the presence of adherence genes from different clinical isolates is a cost-effective tool that would allow researchers to predict the virulence of a certain strain and estimate its potential to adhere to host cells and develop biofilms.

Purpose: Ovarian torsion, being a gynecological emergency, requires to be rapidly diagnosed and treated with minimal consequences on ovarian function after the removal of torsion. As ischemia modified albumin (IMA) is considered a good biomarker in diverse ischemic diseases, the aim of our study was to determine the effect of different ovarian torsion/detorsion models on serum and ovarian homogenates levels of IMA in an experimental study.

Methods: IMA was measured in the serum and ovarian homogenates of 7 groups of female rats (10 animals in each group): 1 - control (no intervention); 2 - sham (only laparotomy); 3 - ischemia group: 3 hours ovarian torsion (OT); 4 - 3 hours OT (ischemia), 1 hour simple reperfusion; 5 - 3 hours ischemia, 1 hour controlled reperfusion that was assured during the first two minutes by opening and closing the clips on the ovarian pedicles in 10 seconds intervals, followed by simple reperfusion; 6 - 3 hours ischemia, 24 hours simple reperfusion; 7 - 3 hours OT, 24 hours controlled reperfusion. The results were analyzed by Welch’s ANOVA and Spearman correlation.

Results: Ischemia increases the IMA in both serum and ovarian homogenates compared to control and sham groups. The controlled reperfusion groups had a statistically significant lower IMA in serum compared to simple reperfusion groups. IMA was found to be higher in the ovarian homogenates of simple reperfusion compared to controlled reperfusion groups.

Conclusion: Our results suggest that controlled reperfusion prevent the processes that increase the IMA in ovarian torsion.

The parasitic copepod Neoergasilus japonicus (Harada, 1930), native to eastern Asia, was collected from Colossoma macropomum (Cuvier, 1818) cultivated in a fish pound in the department of San Martin, Peru in July 2017. The parasite specimens were found attached to the base of the dorsal fin. Neoergasilus japonicus is widespread in different fish species across the world, being in this study recorded for the first time parasitizing a fish in South America. It is probably that exotic fish hosts associated with the fish-culture industry, such us the tilapia, is the responsible for the transportation and introduction into this part of the world.

Juez tercero e imparcial como elemento “premisa” del proceso justo entre Constitución y fuentes supranacionales
Authors: DINACCI FILIPPO RAFFAELE
Published: February 2019

La uniformidad del cuadro normativo europeo y constitucional, requiriendo un juez tercero e imparcial, impone nuevas perspectivas exegéticas, y ello no sólo por la eficacia de las disposiciones procedentes de fuentes superiores, sino porque los requisitos que caracterizan a la jurisdicción representan, por deseo constitucional, el elemento “premisa” del proceso justo. De aquí la exigencia de que los caracteres de la jurisdicción estén tutelados, incluso en esas situaciones que quedan fuera de las previsiones normativas. Y, desde esta perspectiva, se hace necesario recuperar el valor de garantía de las sanciones procesales, “arrinconadas” por una jurisprudencia no siempre en línea con la objetividad del dato normativo.

Crianças no mundo do trabalho adulto: a História de Grilo e as memórias de infâncias perdidas (Recife, 1920-1930)
Authors: Miranda Humberto Silva
Published: February 2019

Este artigo objetiva debater o cotidiano das crianças no mundo do trabalho, no Recife das dé-cadas de 1920 e de 1930. A trajetória de Grilo - apelido de criança do político pernambucano Gregório Bezerra, que viveu nas ruas da capital pernambucana neste período -, será o fio con-dutor desta trama. Em nome do “progresso”, Gregório e outras crianças se inseriram no mun-do do trabalho dos adultos, sobrevivendo a diferentes desafios cotidianos, marcado pela vio-lência e injustiças sociais. Gregório, João, Maria, Francisco e outros meninos e meninas são agentes sociais que fazem parte desta trama, que procura colocar em tela a história de crianças que foram desafiadas a sobreviver aos diferentes modos de exploração imposta pelos interes-ses dos adultos. Por meio da análise dos relatos de memórias, dos recortes de jornais e de ou-tras fontes buscamos produzir a história do Recife a partir das trajetórias de vida desses meni-nos e meninas. É neste cenário urbano que diferentes vidas se encontraram para vivenciar e sobreviver às diferentes formas de abandono e de exploração do trabalho.
O trabalho infantil através das lentes de Juca Martins: informação e arte na produção fotodocumental (1970-1980)
Authors: Etcheverry Carolina Martins , Masiero Claudia Gisele
Published: February 2019

Este estudo pretende analisar as fotografias de Juca Martins, cuja tema está centrado no trabalho infantil, em dois de seus projetos: Trabalho infantil em canavial na Zona da Mata (AL, 1984 e PE, 1979) e Extração de madeira (MG, 1985). O texto está divido em duas partes. Primeiramente, fala-se sobre a trajetória do fotógrafo, sobre fotografia e a produção fotodocumental no Brasil, contextualizando o seu trabalho e, especificamente, as fotografias em questão. Posteriormente, essas obras são analisadas, considerando a sua historicidade e plasticidade. O objetivo é analisar as obras, dialogando com o seu contexto de produção e circulação e a implicação da temática retratada. Pode-se dizer que fica clara a sua intenção documental, ao mesmo tempo que é possível perceber seu caráter artístico, em uma lin-guagem fotográfica que alia informação e expressão. Além disso, as imagens selecionadas remetem à busca pelos direitos das crianças e, consequentemente, pela garantia de uma infância digna. Evidenciam que a exploração de cri-anças é um ponto há tempo questionado e ainda não solucionado em nossa sociedade e, justamente por isso, necessita ser constantemente debatido.
