Campos de sentido e campos de objeto
Authors: Meinhardt Giovani 
Published: March 2022

Os campos de realidade vinculam-se à especificidade de objetos no lar e na instituição educativa de cada aluno. Alunos e famílias atribuem sentidos aos objetos e formalizam ‘realidade’ nos campos que ocupam em seus espaços físicos. As famílias imersas em seu campo de realidade estendem suas compreensões dinâmicas ao campo de realidade escolar. As atribuições de sentidos dialogam ou colidem com o campo de realidade da escola. Este artigo oferece uma reflexão sobre os campos de realidade dos professores, estudantes, famílias e suas conexões.

Background: The aim of this study was to investigate the long-term outcomes of patients who underwent anatomic lung resection for pulmonary aspergilloma and to evaluate the prognostic factors affecting early postoperative morbidity.
Methods: Between January 2007 and January 2017, we retrospectively evaluated a total of 55 patients (40 males, 15 females; mean age: 44.6 years; range, 18 to 75 years) who underwent lobectomy and pneumonectomy for pulmonary aspergilloma. All patients were evaluated for simple or complex aspergilloma based on imaging and thoracotomy findings.
Results: Thirty-two (58.2%) patients presented with hemoptysis. Seven (12.7%) patients underwent emergency surgery due to massive hemoptysis. Postoperative morbidity was observed in 15 (27.3%) patients. Prognostic factors that had an effect on morbidity were resection type, Charlson Comorbidity Index >3, and massive hemoptysis (p<0.05). There was no intra- or postoperative mortality. The five-year survival rate was 89.4%. None of the factors evaluated in the study were associated with survival.
Conclusion: The main finding of this study is the absence of mortality after surgical treatment for pulmonary aspergilloma. The success of surgical treatment depends on the management of postoperative complications.
Mutual information estimation for graph convolutional neural networks
Authors: Landsverk Marius Cervera , Riemer-Sørensen Signe 
Published: March 2022

Measuring model performance is a key issue for deep learning practitioners. However, we often lack the ability to explain why a specific architecture attains superior predictive accuracy for a given data set. Often, validation accuracy is used as a performance heuristic quantifying how well a network generalize to unseen data. Mutual information can be used as a measure of the quality of internal representations in deep learning models, and the information plane provide insights into whether the model exploits the available information in data.
The information plane has previously been explored for fully connected neural networks and convolutional architectures. We present an architecture-agnostic method for tracking a network's internal representations during training, which are then used to create the mutual information plane. The method is exemplified for a graph convolutional neural network fitted on the Cora citation data. We compare how the inductive bias introduced in the graph convolutional architecture changes the mutual information plane relative to a fully connected neural network.

Skandinavisk tidsskrift for yrker og profesjoner i utvikling (SJVD) ble startet ut fra et behov for flere vitenskapelige publiseringskanaler med fokus på det yrkespedagogiske og profesjonsfaglige feltet i Skandinavia. Den første utgaven, publisert i august 2016, tok utgangspunkt i forskningsmiljøet på Institutt for yrkesfaglærerutdanning på OsloMet, den gang HiOA. Fra å være en redaksjon med utgangspunkt i dette miljøet, er redaksjonen utvidet og omfatter i dag flere forskningsmiljøer.
Nina Aakernes fra Institutt for yrkesfaglærerutdanning ved OsloMet har bidratt i redaksjonen fra 2020, og har vært redaktør siden årsskiftet. Britt Karin Utvær fra Institutt for lærerutdanning ved NTNU sluttet seg til redaksjonen i 2021. Fra januar 2022 har vi fått ytterligere to nye redaksjonsmedlemmer, Julie Leonardsen, også fra Institutt for lærerutdanning ved NTNU og Jan Bisgaard fra Københavns Professionshøjskole, Nationalt Center for Erhvervspædagogik. Cecilie Meltzer, tidligere ansatt ved Institutt for yrkesfaglærerutdanning ved OsloMet, har vært redaksjonsmedlem siden 2020. Hun fortsetter i redaksjonen for å bidra til kontinuitet. Vi vil samtidig takke Ellen Beate Hellne-Halvorsen for flere års arbeid som redaktør. Hun fratrådde ved årsskiftet.
Tidsskriftet publiseres på en open acess plattform som driftes av Universitetsbiblioteket ved OsloMet. Det redaksjonelle arbeidet drives i dag på dugnadsbasis uten økonomisk støtte.
Ut fra mengden manus vi får vi tilsendt, ser vi at SJVD er et viktig tilskudd til floraen av vitenskapelige tidsskrift. Vi er åpne for å publisere artikler skrevet både på engelsk og på skandinaviske språk. Ved å publisere på engelsk, kan forfatterne velge å bidra i en internasjonal faglig debatt. Publisering på morsmålet er viktig for å videreutvikle det nasjonale fagspråket og kan lette bruken av artikler i for eksempel yrkesfaglærerutdanningene. Redaksjonen ønsker at tidsskriftet kan bidra på alle disse områdene.
Vi vil rette en stor takk til fagfellene som gjør en uvurderlig jobb ved å bidra til den vitenskapelige kvaliteten på de publiserte artiklene. Vi oppfordrer derfor forfatterne til å bidra til dugnaden ved også å påta seg fagfelleoppdrag. I og med at vi ikke har noen form for finansiering, har vi heller ikke et apparat som tar seg av språkvask og justering av referanser. Det er derfor viktig at forfatterne sørger for språkvask av manus og at referansene er i samsvar med APA 7.
2020 var et turbulent år for SJVD, med stopp av finansiering fra Fakultet fra lærerutdanning og internasjonale studier ved OsloMet, trussel om nedleggelse, og stopp i inntak av artikler. 2021-årgangen var preget av dette, med kun seks publiserte artikler. Med styrking av redaksjonen og økt interesse for tidsskriftet fra ulike yrkesfaglige og profesjonsfaglige miljøer, ser vi 2022 og videre drift av tidsskriftet lyst i møte. Artiklene i 2022-årgangen vil bli utgitt fortløpende etter hvert som de blir klare.
The relationship between distal trunk morphology and object grasping in the African savannah elephant (Loxodonta africana)

Published: March 2022

BackgroundDuring reach-to-grasp movements, the human hand is preshaped depending on the properties of the object. Preshaping may result from learning, morphology, or motor control variability and can confer a selective advantage on that individual or species. This preshaping ability is known in several mammals (i.e.,primates, carnivores and rodents). However, apart from the tongue preshaping of lizards and chameleons, little is known about preshaping of other grasping appendages. In particular, the elephant trunk, a muscular hydrostat, has impressive grasping skills and thus is commonly called a hand. Data on elephant trunk grasping strategies are scarce, and nothing is known about whether elephants preshape their trunk tip according to the properties of their food.MethodsTo determine the influence of food sizes and shapes on the form of the trunk tip, we investigated the morphology of the distal part of the trunk during grasping movements. The influence of food item form on trunk tip shape was quantified in six female African savannah elephants (Loxodonta africana). Three food item types were presented to the elephants (elongated, flat, and cubic), as well as three different sizes of cubic items. A total of 107 ± 10 grips per individual were video recorded, and the related trunk tip shapes were recorded with a 2D geometric morphometric approach.ResultsHalf of the individuals adjusted the shape of the distal part of their trunk according to the object type. Of the three elephants that did not preshape their trunk tip, one was blind and another was subadult.Discussion and perspectivesWe found that elephants preshaped their trunk tip, similar to the preshaping of other species’ hands or paws during reach-to-grasp movements. This preshaping may be influenced by visual feedback and individual learning. To confirm these results, this study could be replicated with a larger sample of elephants.

AbstractJudges, jurors and other triers of fact often rely upon eyewitness evidence in criminal trials, but eyewitness memory is not always accurate and can sometimes be contaminated. The I‐I‐Eye is an evidence‐based teaching aid designed to improve the evaluation of eyewitness evidence in legal settings. We aimed to further test the I‐I‐Eye and examine whether adding an active component to this teaching aid improves its effectiveness. Two experiments (N = 324 and N = 322) were conducted using a 2 (case strength: weak vs. strong) by 3 (teaching aid condition: control vs. passive vs. active) between‐subjects design. Results of both experiments showed that the I‐I‐Eye can help jurors recognize strong eyewitness cases, although it was not particularly effective when the evidence was weak. It was also found that the active component did not further improve sensitivity. We discuss whether teaching aids such as the I‐I‐Eye may assist decision‐makers in the evaluation of eyewitness evidence, while highlighting some of its main limitations found in our results.

Published: March 2022

AbstractMendelian genetics spark the century‐old revolution in genetic engineering. DNA structural engineering may well spark a similar revolution in chemistry. The first few man‐made DNA structures are purely DNA but increased interest in hybrid DNA with other molecules is regaining popularity. Nucleic acids can interact with non‐nucleic acid‐based materials, showing their materialistic flexibility and potential and the prospect of forming new future materials. This review provides a deep materialistic background based on the interaction of nucleic acids with these non‐nucleic acid‐based materials covering comprehensive topics. The non‐nucleic acid materials are broadly divided into biological materials, for example, small‐biomolecules, peptides, proteins, and lipids, and non‐biological materials consisting of metal ions, chemical molecules, low‐dimensional nanomaterials, and micro‐scale polymers. Of significance, combining the unique properties of nucleic acids with these non‐genetic materials can bring about surprising synergistic characteristics and drive attractive applications in bio‐imaging, chem/bio‐sensing, disease therapies, antimicrobial works, and even information storage.

AbstractVirtual reality is a brand‐new technology that can be applied extensively. To realize virtual reality, certain types of human–computer interaction equipment are necessary. Existing virtual reality technologies often rely on cameras, data gloves, game pads, and other equipment. These equipment are either bulky, inconvenient to carry and use, or expensive to popularize. Therefore, the development of a convenient and low‐cost high‐precision human–computer interaction device can contribute positively to the development of virtual reality technology. In this study, a gesture recognition wristband that can realize a full keyboard and multicommand input is developed. The wristband is convenient to wear, low in cost, and does not affect other daily operations of the hand. This wristband is based on physiological anatomy as well as aided by active sensor and machine learning technology; it can achieve a maximum accuracy of 92.6% in recognizing 26 letters. This wristband offers broad application prospects in the fields of gesture command recognition, assistive devices for the disabled, and wearable electronics.

AbstractLoneliness exacerbates psychological distress and increases the risk of psychopathology after trauma exposure. However, it is still unclear whether a lack of social connectedness affects trauma‐related intrusions and the neural processing of fear signals. Moreover, it is uncertain, whether loneliness plays a different role in women and men. A prestratification strategy is used and n = 47 (n = 20 women) healthy lonely individuals and n = 35 controls (n = 18 women) are recruited. Participants are exposed to an experimental trauma and evoked intrusive thoughts in daily life are monitored for three consecutive days. Functional magnetic resonance imaging is used to assess neural habituation to fearful faces and fear learning (conditioning and extinction) prior to trauma exposure. The results reveal a significant interaction between loneliness and sex such that loneliness is associated with more intrusions in men, but not in women. A similar pattern emerges at the neural level, with both reduced amygdala habituation to repeated fearful faces and amygdala hyperreactivity during the conditioning of fear signals in lonely men. The findings indicate that loneliness may confer vulnerability to intrusive memories after trauma exposure in healthy men and that this phenotype relates to altered limbic processing of fear signals.

AbstractDeferoxamine (DFO) is an FDA‐approved iron‐chelating agent which shows good therapeutic efficacy, however, its short blood half‐life presents challenges such as the need for repeated injections or continuous infusions. Considering the lifelong need of chelating agents for iron overload patients, a sustained‐release formulation that can reduce the number of chelator administrations is essential. Here, injectable hydrogel formulations prepared by integrating crosslinked hyaluronic acid into Pluronic F127 for an extended release of DFO nanochelators are reported. The subcutaneously injected hydrogel shows a thermosensitive sol–gel transition at physiological body temperature and provides a prolonged release of renal clearable nanochelators over 2 weeks, resulting in a half‐life 47‐fold longer than that of the nanochelator alone. In addition, no chronic toxicity of the nanochelator‐loaded hydrogel is confirmed by biochemical and histological analyses. This injectable hydrogel formulation with DFO nanochelators has the potential to be a promising formulation for the treatment of iron overload disorders.

AbstractA public trout hatchery in Colorado recorded repeat episodes of morbidity and mortality in early life stages of Rainbow Trout (Oncorhynchus mykiss) stocks. The water source for the affected tanks is a groundwater well with a pH of 6.3 and a ferrous iron concentration of 120 µg/L. Iron oxidizing bacteria (FeOB) were suspected as the underlying cause due to insoluble red particulate matter (iron oxide precipitate) in the water, and the presence of thick red slime (biofilm) that coated tanks and pipes of the facility and adhered to gills, opercula, and fins of fry. On necropsy, gill and fin clippings from moribund fish had mats of adherent red‐orange material. Histopathology revealed severe diffuse proliferative branchitis. There was abundant debris including granular to sheath‐like and stalk‐like pigmented material within the oral and branchial chambers, intimately associated with gill filaments. A Gram preparation demonstrated florid Gram‐negative bacteria within this debris. A Perls’ Prussian blue preparation revealed colocalization of abundant iron. Bacteria were identified morphologically to be of the iron oxidizing bacterial genera Gallionella and Leptothrix. This is the first known report of disease in fish associated with iron‐oxidizing bacteria.

AbstractAnimal models of human diseases play a critical role in medical research. Pigs are anatomically and physiologically more like humans than are small rodents such as mice, making pigs an attractive option for modeling human diseases. Advances in recent years in genetic engineering have facilitated the rapid rise of pig models for use in studies of human disease. In the present review, we summarize the current status of pig models for human cardiovascular, metabolic, neurodegenerative, and various genetic diseases. We also discuss areas that need to be improved. Animal models of human diseases play a critical role in medical research.

AbstractMetal‐organic frameworks (MOFs) are porous coordination polymers formed by metal ions and organic ligands through coordination bonds. In drug delivery applications, MOFs can impart sustained release, targeting, protection of easily degradable drugs, and improved drug solubility. Isoreticular metal‐organic framework‐8 (IRMOF‐8) is a mesoporous MOF with a network topology bridged in the form of an octahedral cluster. Compared with other materials, it has the remarkable advantages of high porosity and a regular pore structure. Curcumin (CUR) is a diketone compound with potent antitumor effects. Due to its poor solubility and stability, its clinical application is limited. Therefore, we used IRMOF‐8 as a carrier for the encapsulation of CUR to overcome the shortcomings of CUR itself and expand its clinical application. In this study, IRMOF‐8 was synthesized through direct mixing of triethylamine (TEA). In vitro cell experiments demonstrated the biocompatibility of IRMOF‐8. Using the solvent adsorption method, CUR was encapsulated by IRMOF‐8 with a drug loading content of 58.86 ± 0.98 wt%. In vitro drug release experiments performed at pH levels of 7.2 and 5.5 showed that the preparation had a sustained‐release effect over 7 days. Through cytotoxicity experiments after drug loading, it was found that CUR@IRMOF‐8 had a strong cytotoxic effect on HepG2 cells, promoted cell apoptosis and intracellular uptake, decreased mitochondrial membrane potential, and increased reactive oxygen species. Hence, CUR@IRMOF‐8 is expected to become an excellent sustained‐release preparation for potential applications in tumor treatment.
