A taste of home: Emotional transnationalism and China Lion Film Distribution in the United States
Authors: Soe Valerie
Published: February 2019

Between 2010 and 2015, China Lion Film Distribution released 55 Chinese-language films in North America on the same day as the films were released in the People’s Republic of China. In 2014, China Lion hit its stride, with a string of seven films that each grossed more than US$100,000 in limited release in North America. By marketing Chinese-language films in the United States to Chinese transmigrant communities rather than to mainstream US audiences, China Lion takes advantage of the emotional transnationalism of Chinese Americans, bringing them a recognizable taste of ‘Home’ in their new place of residence. This article looks at the ways in which China Lion’s recent releases in US multiplexes differ from past attempts to bring Chinese and Hong Kong cinema to North America. China Lion’s success reflects China’s rapidly expanding film industry and the growing relationship between China, Hollywood and the global film market at large, and also reflects the changing demographics of the twenty-first-century Chinese American community.
Leukocentric Hollywood: Whitewashing, Alohagate and the dawn of Hollywood with Chinese characteristics
Authors: Magnan-Park Aaron Han Joon
Published: February 2019

Hollywood’s long-standing practice of leukocentrism is condemned as a false and outdated adherence to an aspect of commercial determinism whereby whitewashing a film is held to ensure its profitability, universality, popularity and social meaningfulness, especially when it involves Asian and Asian American characters. Criticism of this practice came to a head in what became known as ‘Alohagate’, which started with the miscasting of Emma Stone in Aloha (2015) and continued with Doctor Strange (2016), Birth of the Dragon (2016) and plans for the live action version of Disney’s animated Mulan (2020 forthcoming). Asian American filmmakers protested via their #WhiteWashedOut Twitter campaign and drew attention to the targeting of Asians for racist jokes at the 2016 Oscars. The Hollywood response is one of innocent ignorance, which only highlights rather than dispels the deep-rootedness of leukocentrism. These individuals are identified as hūpō haole, Hawaiian for ‘clueless Caucasian/foreigner’, who are granted an opportunity to become enlightened by abandoning their leukocentric bias.

Masculinity, melodrama and quality TV: Reviewing La piovra
Authors: Bauman Rebecca
Published: February 2019

The renowned Italian television series La piovra is known as the first important televisual intervention on the Mafia, but its aesthetic and thematic contributions to contemporary programming are often forgotten in television scholarship. This article positions La piovra in the development of the current trend of ‘quality’ television series by focusing on the show’s exploration of the subgenre of male melodrama. Through an analysis of the two primary characters, the hero Corrado Cattani and the villain Tano Cariddi, we can see how La piovra is not just an exposé of organized crime but is also a complex meditation on the vulnerability of Italian masculinity in a time of gender upheaval in 1980s Italy. It is this particular thematic concern, rather than organized crime, that likens La piovra to the current wave of male-themed quality television series and makes a critical re-evaluation of the series so timely.
Can childhood trauma impact the adult voice through the brain?
Authors: Monti Elisa , Sidtis Diana Van Lancker
Published: February 2019

There is considerable evidence that childhood trauma can affect the whole brain. In a related perspective, studies on brain and voice suggest that it takes a whole brain to produce a voice. Indeed, phonation is highly interconnected with activity at all cerebral levels, from brainstem to cortex, and within all cerebral systems, including limbic, motor, sensorial and cognitive. The authors of this article inquire whether and to what extent it is possible that childhood trauma has an effect on the voice through its influence on the brain. We specifically propose that childhood abuse and neglect could potentially affect voice quality in the adult individual through its effects on brain function leading to measurable physiological sequelae. Findings from voice studies are reviewed to support this proposal.
Analysing the advantages of Aristotle’s two-act structure in comparison with Syd Field’s three-act structure in short comedic animation scriptwriting
Authors: Khalili Sara
Published: February 2019

This article investigates Aristotle’s two-act structure as an alternative for short comedic animation scriptwriting, and examines its advantages in comparison with Syd Field’s three-act structure. In this study, I am more interested in independent short form animation that finds comedy in dramatic situations, rather than being directly constructed as a series of gags. In certain cases, the three-act structure has been attributed to Aristotle. However, as Tierno implies, Aristotle merely suggests a two-act structure in his Poetics, consisting of complication and denouement, which has similarities to and even overlaps with Syd Field’s three-act structure (set-up, confrontation, resolution), so that they have been assumed to be identical by mistake. Meanwhile, there are subtle differences between the two structures, which will be separately discussed in this article. The three-act structure is widely used in Hollywood live-action and animation features. It is also applicable in short scripts but it sometimes appears to encumber, especially in very short animations. A short animation scenarist, who tries to be as minimal as possible, may not want to sacrifice the clarity of the story for the sake of this brevity. By applying an adaptive approach with an analytical-descriptive method, the present article shows how, in Aristotle’s two-act structure, it is possible to create a structured story in the shortest possible form by omitting the ‘set-up’ section and stepping into the heart of the story. The findings of the study reveal that the two-act structure could be a suitable alternative for comedic plots in which stereotypical characters appear as protagonists and the audience is not expected to spend much time building deep identification with them.
How to write a screenplay with a chainsaw
Authors: Tupicoff Dennis
Published: February 2019

The idea for Chainsaw began in two newspaper obituaries steeped in romanticism, anthropomorphism and death. One celebrated the life of an Australian rodeo bull called Chainsaw, the other a Spanish bullfighter. Subsequent research linked to other subjects, from the dangers of chainsaws to Hollywood sex triangles and more: all non-fiction and all, apparently, far from animation. In Chainsaw rotoscoped animation is reality; archival B&W footage is used ironically in the Hollywood dreams and nightmares of the fictional characters. The chainsaw itself is a powerful metaphor for a type of story and a narrative structure. The fictional and non-fictional stories are linked in various ways, set in motion by human drives and desires, cutting through space and time and through the characters’ lives. An old chainsaw safety video provides us with the fictional couple Frank and Ava Gardner, seen then and now, as they move to a bloody denouement. The ‘real’ worlds of bullfighting, rodeo and Hollywood – strange ceremonies devised for entertainment – are saturated in fantasy and romance. In the natural world there is the collateral killing of which humans are unaware. But the trees and beasts and birds will endure after all the human drama and romance are played out.
Screenwriting animation in the essay film: The challenges presented by silenced history
Authors: Turina Romana
Published: February 2019

This article explores the use of animation in the essay film and analyses how screenwriting animation becomes a complex process of translation of the message the film wishes to address. With a focus on issues encountered in the development of two short essay films, Lunch with Family (2016) and San Sabba (2016), the article maps the process that in both cases guided the scripting of animated sequences, and analyses why in the editing room the director chose to use stills from the animations, instead. An example of the narrative techniques applied to mediate silenced history and postmemory in film, this contribution intends to add to the larger discussion on the current state of the art in screenwriting non-fiction.
Libtard gungrabbers and #PewPewLife: Multiple realities in a political issue-centric forum
Authors: Gilpin Dawn R. , Thornton Leslie-Jean
Published: February 2019

The image-sharing social media platform Instagram has become a site for political discourse that combines visual and textual elements. These political conversations often take place in the form of memes or popular graphic sentiments intended for redistribution. Scholars have identified memes as markers of subcultural knowledge that may be used to reinforce beliefs and norms, define social boundaries and disparage outgroups. Gun rights activism in the United States has intensified in an increasingly partisan environment. We examined memes shared via Instagram to popular gun culture hashtags between June 2016 and February 2018. Insofar as memes act as vehicles for subcultural beliefs and values, here they may be seen as representing multiple realities from the perspective of Second Amendment enthusiasts: descriptions of their perceived reality, justifying the need for guns and conservative political positions; the construed reality of what the meme creators and sharers believe to be liberal attitudes; and the aspirational reality of a world that offers unobstructed support for their priorities. In other words, these memes can collectively be said to represent both the truth about the world, as seen by these users, and cultural messages to set power differentials and identity boundaries with Others.
Queer temporalities in Mariana Rondón’s Pelo malo/Bad Hair (2013)
Authors: St-Georges Charles
Published: February 2019

Sometimes criticized for the film’s emphasis on delay and ‘dead time’, the present analysis suggests a reading of the seemingly stagnant plot-line of Mariana Rondón’s Pelo malo/Bad Hair (2013) as an effective rhetorical strategy for interpellating viewers into the ‘sideways’ time of queer childhood – a theoretical framework established by Kathryn Bond Stockton – to explore the intersectional processes at work in the subject formation of Junior, the film’s 9-year-old Afro-Venezuelan protagonist. In contrast to most contemporary Latin American films with child protagonists that serve as embodiments of history, Rondón refuses viewers this temporal distance to depict a child undergoing ghostly erasure by the patriarchal mechanisms that dictate the terms of a nation’s history and citizenship.
The villero cinema of César González
Authors: Gordon Rocio
Published: February 2019

This article focuses on the cinema of César González, a filmmaker born and raised in a villa miseria (shantytown) of Buenos Aires, Argentina. Thanks to digital film technology, González has been able to make his own films in and of the slums without external mediations. This article examines how his films can be thought of as a ‘line of flight’ or escape from the dominant representations of marginalized sectors of society. Using digital technology, in general, and long takes, more specifically, González creates cinematic experiences in which the villero (the slum dweller) becomes an open subject whose agency is reaffirmed.

HIGH TEMPERATURE CYCLIC TEST RIG – A NEW RIG FOR HOT GAS PARTS LIFETIME VALIDATION
Authors: Ammer Wieland , Raddatz Mario , Gampe Uwe , Nussbaum Julien , Ruedel Uwe , Kellerer Rudolf
Published: February 2019

Flexible gas turbine operation requires adapted hot gas parts design and lifetime assessment methods. The High Temperature Cyclic Test Rig (HTCTR) is developed to cyclically test internally cooled components from combustor and turbine sections of gas turbines in close-to-engine conditions for a wide range of operating conditions in order to improve component lifetime management. These advanced tests should serve as basis for new model development and validation for conditions that are more representative of those in an engine than the standard material specimen tests.

Published: February 2019

Increasing demands on the flexibility of steam turbines due to the use of renewable energy sources substantially alters the fatigue strength requirements of components of these devices. Rapid start-ups as well as the increased number of the load cycles applied to the turbines must be handled by design methodologies. The goal of the work presented in this paper was to provide a computational framework applicable to the thermo-mechanical fatigue (TMF) prediction of steam turbine shafts. The so-called Damage Operator Approach by Nagode et al. has been implemented to the software codes and applied to fatigue analysis of the thermo-mechanical material response computed numerically by the finite element analysis. Experimental program conducted in order to identify the material thermo-mechanical behavior and to verify numerical simulations is introduced in the paper. Some results of TMF prediction of a sample steam turbine shaft are shown.

REGARDING CERTAIN AERODYNAMIC SOURCES OF NON-STATIONARY FORCE LOADS ON TURBINE PROFILES
Authors: Radnic Tomáš , Luxa Martin , Šimurda David
Published: February 2019

The paper deals with selected phenomena present in a blade cascade flow field. The presented research was performed on prismatic blade cascades composed mostly of the tip and root sections of the last stage rotor blade of a large output steam turbine. The unstarted supersonic flow on the cascade inlet, the separation of the flow and the swirl line behind the trailing edge have been identified as the possible sources of the unsteady force effects.

Published: February 2019

In this paper, experimental testing of flutter and numerical simulations using a commercial code ANSYS CFX and an in-house code TRAF are performed on an oscillating linear cascade of turbine blades installed in a subsonic test rig. Bending and torsional motions of the blades are investigated in a travelling wave mode approach. In each numerical approach, a rig geometry model with a different level of complexity is used. Good agreement between the numerical simulations and experiments is achieved using both approaches and benefits and drawbacks of each technique are commented in this paper. It is demonstrated that both used computational techniques are adequate to predict turbine blade flutter. It is concluded that validated numerical tools can provide a better insight of flutter phenomena of operationally flexible steam turbine last stage blades.

Comment se portent les Belges ? Qui sont les plus démunis dans notre société ? Pour répondre à ces questions à priori simples, il convient de s’accorder sur ce qu’est le bien-être.

Pour la plupart des gens, la notion de bien-être ne se limite pas aux possessions matérielles et englobe d’autres aspects tels qu’une bonne santé, un emploi du temps judicieux et un environnement de vie agréable.

Malgré tout, la pratique la plus courante consiste à utiliser les revenus comme indicateur du bien-être : selon le seuil de pauvreté officiel européen, une famille est considérée comme pauvre si son revenu est inférieur à 60 % du revenu médian dans la société.

Il est toutefois de plus en plus reconnu que beaucoup de choses importantes dans la vie ne peuvent pas s’acheter. Ainsi, une quantité croissante de recherches empiriques cherche à mesurer à quel point les gens se sentent «heureux» ou «satisfaits de leurs vie». Il ressort de ces recherches que les sentiments de bonheur dépendent significativement de la situation objective des gens : les personnes ayant un revenu plus élevé, une meilleure santé ou un logement de meilleure qualité se déclarent en moyenne plus heureux. Cela fait-il du bonheur un indicateur «adéquat» du bien-être?

Cet indicateur dépend aussi des aspirations, des attentes et des traits de personnalité des individus. Par conséquent, utiliser le bonheur comme unique indicateur du bien-être impliquerait de donner la priorité aux personnes qui se déclarent les plus insatisfaites, mais qui ne se trouvent pas nécessairement dans la situation objective la plus précaire.

Un consortium de chercheurs de la KU Leuven, de l'Université d'Anvers, de l'Université Catholique de Louvain et de l'Université Libre de Bruxelles s’est penché sur ces questions et propose une nouvelle méthode, celle du revenu équivalent, pour mesurer le bien-être individuel. Cette méthode prend non seulement en compte la situation des personnes dans différents domaines de leur vie, mais également la façon dont ces personnes évaluent ce qui est important dans leur vie. Elle vise donc à atteindre un compromis entre les indicateurs purement objectifs et subjectifs du bien-être.

Au moyen d’une vaste enquête menée dans toute la Belgique, ils étudient les divers aspects du bien-être individuel, examinent leur corrélation et comparent le revenu équivalent aux indicateurs standards de bien-être matériel et subjectif.

Les données de cette enquête sont disponibles au niveau individuel. Cela permet d’aller plus loin que la pratique courante analysant les familles dans leur ensemble et d’observer les inégalités existant entre membres d’une même famille au niveau de la consommation et de l’emploi du temps, entre autres.
Persistent Inequality, Corruption, and Factor Productivity
Authors: Dusha Elton
Published: February 2019

I build a model with bequests, financial frictions and corrupt bureaucrats to explain the link between corruption and inequality and its effects on productivity. Because of collateral requirements, profits are determined by wealth. If individual wealth is not publicly observed, taxation is regressive under corruption. When wealth inequality is high, corruption is more prevalent, creating persistent feedback between corruption and inequality. I calibrate the model and investigate the effect of corruption on inequality and TFP. Through regressive taxation, corruption induces wealth levels to inversely affect the productivity selection. This in turn has adverse effects on aggregate TFP.
Standardization of measurement procedures for serum uric acid: 8-year experience from Category 1 EQA program results in China
Authors: Zhang Jiangtao , Luo Wenbo , Zeng Jie , Zhang Tianjiao , Zhou Weiyan , Zhao Haijian , Yan Ying , Hu Cuihua , Ma Rong , Wang Jing , Chen Wenxiang , Zhang Chuanbao
Published: February 2019

Background

Serum uric acid is a critical clinical indicator, and results without equivalence among laboratories cause troubles for disease diagnosis and patient management. External quality assessment (EQA) is a common tool for enhancing harmonization/standardization, therefore, the National Center for Clinical Laboratories in China has initiated a category 1 EQA for serum uric acid measurement since 2010 for evaluating its process of standardization.

Methods

Commutable EQA samples with target values assigned by reference measurement procedures were sent to participant laboratories. Both concentrations were measured 15 times in 3 days then means and intra-laboratory coefficient of variations (CVs) were reported. Biological variation criteria were used for analysis with CLIA88 criteria as a comparison.

Results

A total of 1250 laboratories participated in EQA programs from 2010 to 2017, pass rates calculated according to desirable specifications in biological variation database were on a rise overall and inter-laboratory mean bias and CVs were on a decrease. Homogeneous systems showed better inter-laboratory CVs and pass rates than heterogeneous systems. For the mostly used measurement systems; Abbott, Beckman, Roche Modular, Siemens and Hitachi showed desirable performances other than Roche Cobas, according to biological variation criteria.

Conclusions

Our study provides reliable information on the standardization of measurement procedures for serum uric acid for manufacturers and laboratories. Further improvements for standardization are still needed to make laboratories more patient-centered.

Published: February 2019

Background

Procalcitonin (PCT)-guided antibiotic stewardship (ABS) has been shown to reduce antibiotics (ABxs), with lower side-effects and an improvement in clinical outcomes. The aim of this experts workshop was to derive a PCT algorithm ABS for easier implementation into clinical routine across different clinical settings.

Methods

Clinical evidence and practical experience with PCT-guided ABS was analyzed and discussed, with a focus on optimal PCT use in the clinical context and increased adherence to PCT protocols. Using a Delphi process, the experts group reached consensus on different PCT algorithms based on clinical severity of the patient and probability of bacterial infection.

Results

The group agreed that there is strong evidence that PCT-guided ABS supports individual decisions on initiation and duration of ABx treatment in patients with acute respiratory infections and sepsis from any source, thereby reducing overall ABx exposure and associated side effects, and improving clinical outcomes. To simplify practical application, the expert group refined the established PCT algorithms by incorporating severity of illness and probability of bacterial infection and reducing the fixed cut-offs to only one for mild to moderate and one for severe disease (0.25 μg/L and 0.5 μg/L, respectively). Further, guidance on interpretation of PCT results to initiate, withhold or discontinue ABx treatment was included.

Conclusions

A combination of clinical patient assessment with PCT levels in well-defined ABS algorithms, in context with continuous education and regular feedback to all ABS stakeholders, has the potential to improve the diagnostic and therapeutic management of patients suspected of bacterial infection, thereby improving ABS effectiveness.
Use of the Multi-Agent Paradigm in Sustainable Tourism
Authors: Husáková Martina
Published: February 2019

Complex systems are characterised by a huge amount of components, which are highly linked with each other. Tourism is one of the examples of complex systems collecting various activities leading to the enrichment of travellers in the view of receiving new experiences and increasing economic prosperity of specific destinations. The complex systems can be investigated with various bottom-up and top-down approaches. The multi-agent-based modelling is the bottom-up approach that is focused on the representation of individual entities for the exploration of possible interactions among them and their effects on surrounding environments. These systems are able to integrate knowledge of socio-cultural, economic, physical, biological or environmental systems for in-silico models development, which can be used for experimentation with a system. The main aim of the presented text is to introduce links between tourism, complexity and to advocate usefulness of the multi-agent-based systems for the exploration of tourism and its sustainability. The evaluation of suitability of the multi-agent systems in tourism is based on the investigation of fundamental characteristics of these two systems and on the review of specific applications of the multi-agent systems in sustainable tourism.
YouTube as an Airlines Marketing Tool
Authors: Pásková Martina , Hruška Jan , Zelenka Josef
Published: February 2019

Multimedia communication through social media has been experiencing constantly growing significance in the field of airline marketing. The aim of the research presented in this paper was to find out and, with the help of both qualitative and quantitative analyses, describe the way YouTube is used by airlines. The research was conducted in the form of a comparative study with the objective of identifying the difference between YouTube performance of full-service carriers (FSCs) and low-cost carriers (LCCs). The intention was to identify which factors influence the effectiveness of airline marketing conducted via YouTube an as well as the way in which they do it. Analysis of selected data was facilitated by social media analytics tool SocialBakers, content analyses and a correlation analysis of YouTube metrics, selected on the base of previous research results. The research data were collected twice during the year 2017 in order to reflect changes over time. Research results showed that FSCs build their YouTube channels more systematically than LCCs. FSCs offer a substantially wider range of video topics and often sort out topics of their videos in a more detailed way. Regarding the basic metrics of YouTube channels (total number of views, number of subscribers), FSCs surpass LCCs significantly. One reason for their much higher rate of views is the fact that FSCs use celebrities more frequently, and frequently they offer high-quality impression/relationship airline presentation.
Anthropology of Tourism: Researching Interactions between Hosts and Guests
Authors: Půtová Barbora
Published: February 2019

This study focuses on the theoretical analysis of social interaction and relationship between guests and hosts from the perspective of anthropology of tourism. In the 1960s and 1970s, attention was paid predominantly to anthropological reflection of negative socio-cultural impacts of tourism on host communities. However, towards the end of the 1980s and during the 1990s the research focus began to shift towards an analysis and interpretation of the influence of commodification on the perceptions of identity and authenticity of the host culture, while the positive aspects of tourism began to be recognized as well. This study aims to present an overview of the basic approaches within the anthropology of tourism to social interaction between guests and hosts. The objective of the study is to provide a summary of miscellaneous approaches to and views on this issue.
The use of in vitro assays for the assessment of cytotoxicity on the example of MTT test
Authors: Twarużek Magdalena , Zastempowska Ewa , Soszczyńska Ewelina , Ałtyn Iwona
Published: February 2019

In recent years, biological tests have been developed based on cell cultures and successfully used to the hygienic assess of a variety of samples. In vitro assays become the complement of conventional chemical methods. They do not narrow the results only to the quantitative and qualitative information on toxic substances, but also increase knowledge on the direct impact on the organism. They are also an alternative for animal testing, which are currently given up for ethical reasons. At present, the market is steadily increasing in the number of tests and bio-assay techniques. Based on our own studies we conclude that the MTT test is perfect as a diagnostic method for evaluating the cytotoxicity of materials of different composition such as mycotoxins, pesticides, bacterial cultures, moulds isolates, food, feed, as well as a vast spectrum of other environmental samples.

In this paper the periodic even functions for which all the regular Riemann sums vanishe are called special periodic even functions. A construction of some of them is put forward, this one rest on the Fourier serie and H. Davenport’s estimations concerning the Moebius function. The special periodic even functions seem linked to the number theory, as this can be seen on the Fourier serie result, on the proposed constructions and on the proof that such functions cannot belong to the Wiener algebra.

Design of Digital Control System for Line Following Robot
Authors: Abdulhamid Mohanad , Mutheke Muindi
Published: February 2019

Design of mobile robots has become an increasingly growing trend in the technology of modern times. They are very attractive engineering systems, not only because of many interesting theoretical aspects concerning kinematics, intelligent behavior and autonomy, but also because of applicability in many human activities. A typical example is the line following robot (LFR). In order for a LFR to function effectively, it must demonstrate excellent line tracking control. This is achieved by having accurate and responsive control algorithms as well as high precision color sensor systems. This paper proposes a system to show that good line tracking performance can be achieved with moderately simple digital control algorithms. The platform used is a differentially driven wheeled robot constructed using the Lego Mindstorms components. The simulation models are presented and analyzed using MATLAB Simulink. The main programming environment is the EV3 Software.
Kolozsvár és az egyetem az első világháború éveiben
Authors: Toth Szilárd
Published: February 2019

The inhabitants of Kolozsvár, like the inhabitants of the other cities of the Austro- Hungarian Monarchy, or like the bourgeoisie from other cities from Europe, received the outbreak of World War I with great enthusiasm. At the beginning of the 20th century, there were no televisions and radio stations, and the entertainment facilities were more limited compared to today’s and the outbreak of a war was considered a world sensation. It brought something new in the „gray everyday life”, there was something to talk about, there was a reason waiting for the fresh news in the newspapers. To men, especially young officers, opened the opportunity to advance rapidly in military careers, and at the same time facing the life threats could bring them glory, increasing their chances of winning the hearts of young ladies. And, of course, everyone was certain of victory and of surviving the war. Soon, however, the inflation associated with the war knocked on Kolozsvár, and dearth years came.  
The purpose of this study is to analyze the impact of the World War I on the city and the university. I analyzed the economic and social impact of war on both the city and the university. It was clear that the war had not only negative but also positive effects: it encouraged the service sector, trade, promoted female emancipation, boosted the film production, at the University was established the Department of Orthopedics, etc. But despite all this, it had a number of negative effects on the population of the city: war victims, the decline of the living standards, the increase of the rate of criminality, the damage of the buildings of the university and the city as well, etc. There is still much to discover for the researchers on this topic, and my humble attempt will hopefully inspire those interested in this topic.

Authors: Oliveira Célia Carneiro , Mourão Nadja Maria
Published: February 2019

O artigo apresenta uma reflexão sobre a leitura e releitura de objetos biográficos, lembranças de família e as histórias e possíveis estórias que trazem valores intangíveis para objetos, valores repassados de uma geração à outra. Objetos que falam a respeito das experiências de construção afetiva do passado. Busca-se investigar e identificar alguns objetos relacionados à vida  humana em contexto urbano e  relatar a passagem desses objetos na história contemporânea. Os bens que conservamos durante décadas podem ser considerados espelhos de nossas experiências da passagem do tempo. A metodologia da pesquisa, após as revisões bibliográficas, analisa os termos utilizados na pesquisa como: design para a inovação social; cultura, identidade e memória; pertencimento e o valor sustentável do guardar e cuidar. Em um estudo de caso, no município de Matozinhos, observam-se os eventos culturais, personagens locais e o patrimônio. Após seleção do grupo de estudo, são realizadas palestras e oficinas, sobre a memória cultural e o patrimônio material e imaterial da região, para jovens e adultos. Entre os resultados, registram-se a relação da comunidade com os eventos culturais e o desenvolvimento de produtos artesanais. Verifica-se um potencial de valorização da cultura, por meio da memória cultural pela relacionada aos objetos.
A Onipresença do Design

Published: February 2019

Este artigo discute os desdobramentos do conceito e das práticas do design a partir de seu núcleo semântico que se encontra na noção de projeto.Assim considerado, os inumeráveis níveis e facetas de materialização e operacionalidade do design derivariam da fonte primeira que reside na projeção mental do ato de conceber, uma projeção que é colocada à prova no teste de sua realização tendo em vista os matérias, meios e técnicas de que cada momento histórico dispõe. Tomando como base a pirâmide de Mensvoort dos degraus ascendentes que são percorridos por uma invenção tecnológica, são explorados os níveis de penetração e aceitação dos designs na vida social.

Pelotas, nessa esteira, a partir da segunda metade do século XIX, fez-se cenário de referência às artes gráfi - cas. Impulsionada pelo apogeu cultural e econômico, pelo acesso aos insumos europeus oportunizado pelo Porto de Rio Grande, o parque gráfico se qualificou através da importação de maquinário, dos clichês, papéis e tintas especiais importados da Europa, mais precisamente, oriundos de Portugal, Espanha, França, Alemanha e Inglaterra.
Electrophysiological Characterization of Networks and Single Cells in the Hippocampal Region of a Transgenic Rat Model of Alzheimer’s Disease
Authors: Heggland Ingrid , Kvello Pål , Witter Menno P.
Published: February 2019

The hippocampus and entorhinal cortex (EC) are areas affected early and severely in Alzheimer’s disease (AD), and this is associated with deficits in episodic memory. Amyloid-β (Aβ), the main protein found in amyloid plaques, can affect neuronal physiology and excitability, and several AD mouse models with memory impairments display aberrant network activity, including hyperexcitability and seizures. In this study, we investigated single cell physiology in EC and network activity in EC and dentate gyrus (DG) in the McGill-R-Thy1-APP transgenic rat model, using whole-cell patch clamp recordings and voltage-sensitive dye imaging (VSDI) in acute slices. In slices from transgenic animals up to 4 months of age, the majority of the principal neurons in Layer II of EC, fan cells and stellate cells, expressed intracellular Aβ (iAβ). Whereas the electrophysiological properties of fan cells were unaltered, stellate cells were more excitable in transgenic than in control rats. Stimulation in the DG resulted in comparable patterns in both groups at three and nine months, but at 12 months, the elicited responses in the transgenic group showed a significant preference for the enclosed blade, without any change in overall excitability. Only transient changes in the local network activity were seen in the medial EC (MEC). Although the observed changes in the McGill rat model are subtle, they are specific, pointing to a differential and selective involvement of specific parts of the hippocampal circuitry in Aβ pathology.
Oleic acid induces migration through a FFAR1/4, EGFR and AKT-dependent pathway in breast cancer cells

Free fatty acids (FFAs) are an energy source, and induce activation of signal transduction pathways that mediate several biological processes. In breast cancer cells, oleic acid (OA) induces proliferation, matrix metalloproteinase-9 (MMP-9) secretion, migration and invasion. However, the signal transduction pathways that mediate migration and invasion induced by OA in breast cancer cells have not been studied in detail. We demonstrate here that FFAR1 and FFAR4 mediate migration induced by OA in MDA-MB-231 and MCF-7 breast cancer cells. Moreover, OA induces migration, invasion, AKT1 and AKT2 activation, 12-LOX secretion and an increase of NFκB-DNA binding activity in breast cancer cells. Cell migration requires FFAR1, FFAR4, EGFR, AKT and PI3K activity, whereas invasion is mediated though a PI3K/Akt-dependent pathway. Furthermore, OA promotes relocalization of paxillin to focal contacts and it requires PI3K and EGFR activity, whereas NFκB-DNA binding activity requires PI3K and AKT activity.

In contrast to various other mammalian species, conventionalin vitrofertilization (IVF) with horse gametes is not reliably successful. In particular, stallion spermatozoa fails to penetrate the zona pellucida, most likely due to incomplete activation of stallion spermatozoa (capacitation) underin vitroconditions. In other mammalian species, specific capacitation triggers have been described; unfortunately, none of these is able to induce full capacitation in stallion spermatozoa. Nevertheless, knowledge of capacitation pathways and their molecular triggers might improve our understanding of capacitation-related events observed in stallion sperm. When sperm cells are exposed to appropriate capacitation triggers, several molecular and biochemical changes should be induced in the sperm plasma membrane and cytoplasm. At the level of the sperm plasma membrane, (1) an increase in membrane fluidity, (2) cholesterol depletion and (3) lipid raft aggregation should occur consecutively; the cytoplasmic changes consist of protein tyrosine phosphorylation and elevated pH, cAMP and Ca2+concentrations. These capacitation-related events enable the switch from progressive to hyperactivated motility of the sperm cells, and the induction of the acrosome reaction. These final capacitation triggers are indispensable for sperm cells to migrate through the viscous oviductal environment, penetrate the cumulus cells and zona pellucida and, finally, fuse with the oolemma. This review will focus on molecular aspects of sperm capacitation and known triggers in various mammalian species. Similarities and differences with the horse will be highlighted to improve our understanding of equine sperm capacitation/fertilizing events.
Turning Observed Founder Alleles into Expected Relationships in an Intercross Population

Pedigree-derived relationships for individuals from an intercross of several lines cannot easily account for the segregation variance that is mainly caused by loci with alternative alleles fixed in different lines. However, when all founders are genotyped for a large number of markers, such relationships can be derived for descendants as expected genomic relationships conditional on the observed founder allele frequencies. A tabular method was derived in detail for autosomes and the X-chromosome. As a case study, we analyzed litter size and body weights at three different ages in an advanced mouse intercross (29 generations, total pedigree size 19,266) between a line selected for high litter size (FL1) and a highly inbred control line (DUKsi). Approximately 60% of the total genetic variance was due to segregation variance. Estimated heritability values were 0.20 (0.03), 0.34 (0.04), 0.23 (0.03), 0.41 (0.03) and 0.47 (0.02) for litter size, litter weight and body weight at ages of 21, 42 and 63 days, respectively (standard errors in brackets). These values were between 12% and 65% higher than observed in analyses that treated founders as unrelated. Fields of applications include experimental populations (selection experiments or advanced intercross lines) with a limited number of founders, which can be genotyped at a reasonable cost. In principle any number of founder lines can be treated. Additional genotypes from individuals in later generations can be combined into a joint relationship matrix by capitalizing on previously published approaches.
