Published: April 2021

Abstract

Food products with the brand contain the meaning of sarcasm cannot have MUI halal certificate because it is considered to contain language that is not by following Islamic Sharia law and muslim consumers must consume food products that are not only halal but also good in the entire the production process. This research used a qualitative descriptive method that aimed to find out Muslim consumers’ perception towards food products without halal certificate with the brand contain the meaning of sarcasm. The results show that Muslim consumers are less concerned with halal certificates because of their perception that although halal certificates are important, it is not a problem consuming non-halal certified food products as long as they think that the composition is halal in perception, sarcasm is not a problem for Muslim consumers and the presence of halal certificates is only an added value for a food product.

Keywords: Perception, Muslim Consumers, Sarcasm, Halal Certificate

 

Abstrak

Produk makanan dengan merek bermakna sarkasme tidak dapat mengantongi sertifikat halal MUI karena dinilai mengandung bahasa yang tidak sesuai hukum syariat Islam dan sebagai konsumen harus mengonsumsi produk makanan yang tidak hanya halal tetapi juga baik keseluruhannya. Penelitian ini menggunakan metode deskriptif kualitatif dengan tujuan memberikan gambaran mengenai persepsi konsumen muslim terhadap produk makanan tidak bersertifikat halal dengan merek bermakna sarkasme. Hasil penelitian menunjukkan konsumen muslim kurang peduli terhadap sertifikat halal karena persepsinya bahwa meskipun sertifikat halal penting namun tidak masalah mengonsumsi produk makanan tidak bersertifikat halal selama menurut mereka komposisinya halal dalam persepsinya, bahasa sarkasme bukan masalah bagi konsumen muslim dan hadirnya sertifikat halal hanya sebagai nilai tambah bagi suatu produk makanan.

Customer order scheduling with job-based processing on a single-machine to minimize the total completion time
Authors: Çetinkaya Ferda Can , Yeloğlu Pınar , Çatmakaş Hale Akkocaoğlu
Published: April 2021

This study considers a customer order scheduling (COS) problem in which each customer requests a variety of products (jobs) processed on a single flexible machine, such as the computer numerical control (CNC) machine. A sequence-independent setup for the machine is needed before processing each product. All products in a customer order are delivered to the customer when they are processed. The product ordered by a customer and completed as the last product in the order defines the customer order’s completion time. We aim to find the optimal schedule of the customer orders and the products to minimize the customer orders’ total completion time. We have studied this customer order scheduling problem with a job-based processing approach in which the same products from different customer orders form a product lot and are processed successively without being intermingled with other products. We have developed two mixed-integer linear programming models capable of solving the small and medium-sized problem instances optimally and a heuristic algorithm for large-sized problem instances. Our empirical study results show that our proposed tabu search algorithm provides optimal or near-optimal solutions in a very short time. We have also compared the job-based and order-based processing approaches for both setup and no-setup cases and observed that the job-based processing approach yields better results when jobs have setup times.
Personal and Group Professional Identity in the 21st Century Case Study: The School Counseling Profession
Authors: Heled Einat , Davidovitch Nitza
Published: April 2021

The current study focuses on the concept of professional identity in the school counseling profession, its definition and measurement. According to the definition in this study, the concept of “professional identity” is divided in two: personal professional identity, which is the practitioner’s sense of belonging to and solidarity with the profession, and group professional identity, which includes the features attributed to the profession, both by those who belong to it and by those who do not practice it, and makes it possible to discern between professions.

The school counseling profession, occupied mainly by women, is contending with a lack of clarity regarding its role definition, role boundaries, and demands. Therefore, despite the change in the status of the profession in recent years, various issues impede the group professional identity of school counseling and the personal profession identity of its practitioners. This study is the first to examine the professional identity of school counselors on two levels: personal and group, among school counselors in Israel.

The study included 174 school counselors who completed two professional identity scales constructed for the purpose of the study. Each scale underwent factor analysis, and a significant association was found between the two scales and the factors they comprised. The research findings indicate that the personal professional identity of school counselors is affected by their group professional identity, and vice versa.

The research findings indicate the need to distinguish in future studies between personal and group professional identity, both in the school counseling profession and in other professions, particularly in a world characterized by professional mobility where current professions will become irrelevant while others will be in demand and there may be a need to define the personal and group professional identity of workers.
HPCGRA - An Orthogonal Designed CGRA Generator for High Performance Spatial Accelerators
Authors: Silva Lucas , Canesche Michael , Ferreira Ricardo , Nacif José Augusto
Published: April 2021

Recently, the increasing adoption of domain-speciﬁc architectures to execute kernels with high computing density and the exploration of sparse architectures using Systolic Arrays created the ideal scenario for using Coarsegrained reconﬁgurable architectures (CGRAs) to accelerate applications. Unlike Systolic Array, CGRA can run different kernel sets and keep a good balance between energy consumption and performance. In this work, we present the HPCGRA, an orthogonal designed CGRA generator for high-performance spatial accelerators. Our tool does not require any expertise in Verilog design. In our approach, the CGRA is designed and implemented in an orthogonal fashion, through wrapping the main building blocks: functional units, interconnection patterns, routing, and elastic buffer capabilities, conﬁguration words, and memories. It optimizes and simpliﬁes the process of creating CGRAs architectures using a portable description (JSON ﬁle) and generating a generic, scalable, and efﬁcient Verilog RTL code with Veriloggen. The tool automatically generates CGRA with up to 46x66 functional units, reaching 1.2 Tera ops/s.

A identificação de desenvolvedores de software globalmente distribuídos, especialistas em uma tecnologia, para a manutenção de software tornou-se uma atividade complexa, com alto consumo de tempo e suscetível a falhas de decisão quando realizada em umaúnica base de dados local. Esta crescente complexidade se deve, sobretudo, aos requisitos que os sistemas contemporâneos demandam. Neste contexto, a busca por especialistas para as atividades de manutenção em bases diversificadas tornou-se necessária, o que exige um poder de processamento crescente para recuperar as informações em diferentes repositórios. Este artigo apresenta uma abordagem que visa prover um ambiente que trata a busca de especialistas em diferentes repositórios com o objetivo de apoiar a tomada de decisão para a manutenção de software. Nossa proposta foi executada em um ambiente computacional convencional e em um de alto desempenho, este último apresentando um diferencial em relação ao processamento das bases de dados distribuídas.

Com o avanço da tecnologia e sua dependência no cotidiano, a computação de alto desempenho (HPC) passou a ser uma das principais áreas de pesquisa e investigação na computação. Os ambientes de alto desempenho são comumente utilizados em aplicações que necessitam processar uma variedade de informações e obter o resultado em um tempo limitado para a aplicação. Por conta disso, os ambientes de alto desempenho devem trabalhar de forma eﬁciente para atender as demandas da aplicação e obter os resultados de forma rápida. Para que um ambiente de alto desempenho trabalhe de forma otimizada, é fundamental a escolha de um sistema gerenciador de recursos (SGR) eﬁciente que atenda as necessidades do da aplicação em questão. Por esse motivo, o objetivo deste trabalho foi avaliar e comparar a performance de dois SGRs SLURM e OAR em uma aplicação cientíﬁca real de previsão ionosférica, a ﬁm de veriﬁcar qual deles atende melhor as necessidades e requisitos para essa aplicação. Os experimentos foram realizados em um cluster de uso dedicado localizando no Centro Regional Sul do INPE em Santa Maria, e possui 5 nós de processamento e um de controle. Foram realizados experimentos para quatro dias diferentes, e após avaliadas estatísticas referentes a taxa média de uso de CPU, memória e tempo total de execução. O SLURM apresentou melhores resultados na grande maioria das avaliações, incluindo um menor tempo total de processamento para os quatro dias simulados, quando comparado à solução com o OAR.

Published: April 2021

A descrição de workﬂows cientíﬁcos através de uma linguagem padrão garante, entre outras coisas, portabilidade e escalabilidade aos ﬂuxos de trabalhos cientíﬁcos. Ao encontro da portabilidade e reprodutibilidade, os contêineres representam uma forma de virtualização leve. Dessa forma, o presente trabalho propõe-se a investigar os impactos gerados pelos contêineres no desempenho de workﬂows cientíﬁcos através da execução do workﬂow Hecil. A engine de workﬂow Toil foi utilizada para a leitura e execução do ﬂuxo e duas estratégias conteinerizadas são utilizadas para o escalonamento das tarefas. Os resultados mostram que o controle de criação e remoção de contêineres feito pelo Toil pode representar um gargalo na execução de workﬂows.

Kants Konzeption der Tugend als Habitus der Freiheit
Authors: Trampota Andreas
Published: April 2021

This study, through an interpretation of primary texts as well as a comparative analysis of ancient virtue ethics, brings into sharp focus Kant’s own conception of virtue. Distinctive to that conception is not only strength of will, a theme typically emphasized by scholars, but also what the author calls the habit of freedom—a habit emerging from the strength of lawgiving reason, and yet a habit accompanied by “lightness.” This “ease” is no mere facile uniformity resulting from habitual action, but must be understood as a free skill. Hence, the foundation of the practice of virtue leading to inner freedom is a state of mind enabling both free deliberation concerning principles and also a corresponding determination of the will.
Defence in a Changing World
Authors: Voss Mathias
Published: April 2021

The author takes the reader on a swift and sweeping ride through different aspects of defence. What is the core of defence in general? And what is defence today for the most prominent of all defensive alliances, for NATO, which is in the midst of a reflection process on what its role in the future should be?

The notoriously vague and shadowy term “defence” is illuminated from different angles, culminating in the newly introduced model of “strategical analysis”. The historical perspective comprises examples varying from China’s Great Wall to the Israeli-Arab Six Days War and NATO’s history with a specific focus on its understanding of defence from its foundation, through all three ages of its existence and into today’s still and again changing world. More insights are drawn from the application of the prevalent judicial, political and military strategic approaches and terms.

From this kaleidoscopic view, the author draws practical conclusions and formulates clear and pointed recommendations for the persistent and particularly in NATO very current discussion about how the understanding of defence should – or should not – evolve.

Published: April 2021

A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) é uma classificação desenvolvida pela Organização Mundial de Saúde (OMS). A partir de uma revisão da Classificação Internacional de Deficiências, Incapacidades e Desvantagens (CIDID), fez-se uma mudança de contexto, do enfoque negativo da deficiência e incapacidade para uma perspectiva positiva com ênfase nas atividades e na participação do indivíduo com alterações de função e/ou da estrutura do corpo (FARIAS; BUCHALLA, 2005). Esta classificação apresenta diferentes objetivos, sendo que, primordialmente pode oferecer um olhar sobre a funcionalidade e incapacidade global do indivíduo, assim como padronizar informações a serem utilizadas por diferentes profissionais, tais como: fisioterapeutas, fonoaudiólogos, professores, entre outros. Nesta padronização de informações, pode-se incluir o ambiente escolar. Este estudo teve como objetivo mapear publicações sobre o uso da CIF em ambiente escolar inclusivo. O método adotado foi uma revisão da literatura de caráter retrospectivo, em três indexadores de produção científica: Scielo, Lilacs e Pubmed. Resultou dessa busca 91 artigos, e, após a leitura dos resumos, 16 artigos preenchiam os critérios e foram lidos na íntegra. Verificou-se que há escassez de publicações sobre o tema e constatou-se a necessidade de novos estudos que contemplem esta temática. Uma vez que a CIF não classifica as pessoas, mas descreve a sua funcionalidade e incapacidade, é necessário que os profissionais inseridos no contexto escolar a dominem a fim de promover programas e políticas que respondam eficientemente às demandas de aprendizagem e desenvolvimento do indivíduo com deficiência, ampliando sua participação em atividades escolares e sociais.
A contribution of Wendt's idealism to security studies
Authors: Stanković Nevena
Published: April 2021

One of the key novelties that constructivism introduces to International Relations theories is the term "ideas", as a starting point for understanding, as well as constructing social reality. Because of plenty variations in defining the term "ideas" by different social constructivists, the author in this article aims to analyze Alexander Wendt's approach, with a focus on its significance to security studies. By reviewing Wendt's basic presumptions about idealism, rump materialism (of human nature), material and identity needs, including distinction between materiality and objectivity, the author attempts to make conclusions on possibilities of implementation of these presumptions in researching security phenomena and processes, or, in other words, critically evaluate potential contribution, as well as flaws, for theorizing about security issues. In conclusion, the author suggests that there is undoubtedly significant contribution embedded, primarily, in constitutive versus traditionally dominate causative approach to material factors, especially interests and power, in regard to ideational factors, and measure in which ideas constitute material factors (constituting power by interests, and interests by ideas), as well as claims that ideational constructions can also be real and objective, and emotions such as fear, insecurity and aggression are essential to human nature, result of unfulfilled needs, and eventually, social constructions. Finally, applied to security issues, the most important Wendt's contribution is in the fact that accepting both material and ideational, not just causality, but also constitution, is the best approach for the security research field. Understood in this way, it leads to qualitatively different analyses of the security phenomena and processes, and at the same enables including various variables significant for understanding and, maybe, predicting security dynamics, those that were excluded from the analyses as a result of domination of materialistic approach. Moreover, majority of security phenomena, including risks and threats, and also factors that influence the behavior of security actors and security actions in general, are ideational constructions, which is what makes Wendt's approach vital for dealing with security issues, especially having in mind fact that it opens wide possibilities for practical implementation, potentially leading to new theoretical perspectives in security studies.
The mediation of self-compassion and other constructs: Significance in resilience, depression and anxiety among students

Introduction. Contemporary studies suggest present affective and stress related difficulties such as depressivenes, anxiousness and related states among students of different levels and backgrounds of studies[1,2] hardships that might appear later on, during education and professional activities, depending of the duration and mood severity[3], but also different factors that might play potential protective roles during the whole process[4,5]. Objective. To examine the mediation effects of variables positive lateral generalization, perceived social support and self-compassion in a relationship between depression and anxiety with resilience. Method. A cross-sectional research was conducted in Serbian speaking area on 147 students (108 females (73,5%) and 39 males (26,5%)) of different courses and levels of education, and six different hypothethical single mediator models were examined between anxiety, depression and resilience with the intercession of three mediators: perceived social support, lateral generalisation and self-compassion. Results. Results indicate a non-significant relationship between anxiety and perceived social support (r=-0.09; p>0.05) so that assumption for mediation analysis was not met for furter examination for this model. Perceived social support did not mediate the relationship between depression and resilience significantly (b=0.02; p >0.05, 95% Bca CI [-0.03, 0.08]) which was also the case for lateral generalization (b=0.03; p>0.05, 95% Bca CI [-0.01, 0.10]) as well as in the case between anxiety and resilience (b=0.02; p>0.05, 95% Bca CI [-0.01, 0.09]), whilst significant mediation effect of self-compassion was observed both in relationship between depression and resilience (b=-0.24 p<0.01, 95% Bca CI [-0.38, -0.13]; PM=0.50) as well as in the case of anxiety and resilience (b=-0.23; p<0.01 95% Bca CI [-0.38, -0.12]; PM=0.48). Conclusion. Results indicate a significant contribution of self-compassion in states of depressiveness and anxiousness and its potential role in resilience and well-being, but the directions of effects is not possible to discern due to the cross-sectional nature of the research.
Influence of convectively coupled equatorial Kelvin waves on March-May precipitation over East Africa
Authors: Okello Ochieng , Tan Guirong , Ongoma Victor , Nyandega Isaiah
Published: April 2021

Convectively coupled equatorial Kelvin waves (CCEKWs) are those types of equatorially trapped disturbances that propagate eastward and are among the most common intra-seasonal oscillations in the tropics. There exists two-way feedback between the inter-tropical convergence zone (ITCZ) and these equatorially trapped disturbances. Outgoing Longwave Radiation (OLR) was utilized as a proxy for deep convection. For CCEKWs, the modes are located over the West Atlantic, equatorial West Africa, and the Indian Ocean. The influence of other circulations and climate dynamics is studied for finding other drivers of climate within East Africa. The results show a positive relationship between Indian and Atlantic Oceans Sea Surface Temperatures and March-May rainfall over equatorial East Africa over the period of 1980 to 2010. This influence is driven by the Walker circulation and anomalous moisture influx enhanced by winds. Composite analysis reveals strong lower-tropospheric westerlies during the active phase of the CCKWs activities over Equatorial East Africa. The winds are in the opposite direction with the upper-tropospheric winds, which are easterlies. Singular Value Decomposition shows a strong coupling interaction between rainfall over equatorial East Africa and CCKWs. This study concludes that Kelvin waves are not the main factors that influence rainfall during the rainy season. Previous studies show that the main influencing factors are ITCZ, El-Nino Southern Oscillation (ENSO), and tropical anticyclones that borders the African continent. However, CCKWs are a significant factor during the dry seasons.

Published: April 2021

The usage of Unmanned Aerial Vehicles (UAVs) is accessible for different applications to a wide range of users. However, this wide range of users raises a great concern about the threat (passive or active threats) of malicious actors who can use UAVs for criminal activities. The detection of UAVs is considered to be the first step in the process of UAVs countering (c-UAV). Nowadays, the c-UAV applications offer systems that include different sensors such as electro-optical, thermal, acoustic, radar and radio frequency sensors. Information gathered by these sensors can be fused in order to increase the reliability of threat's detection, classification and identification. It is necessary to have datasets from the different sensors in order to develop methods and algorithms for detection and classification of UAVs. This paper presents a dataset of communication signals between the drone and the control station that is used in the process of detection and classification.

Objectives: Condyle fractures constitute 17.5–52% of all mandibular fractures. Our first aim was to investigate whether panoramic radiography or LSP images with lower radiation dose can be used instead of CBCT in the diagnosis of vertical condylar fractures. The second aim of the study was to compare observers' capabilities in diagnosing these fractures.

Materials and Methods: A sample consisting of 15 fresh cadaver mandibles with 30 condyles frozen within 24 hours post-mortem was randomly selected. Vertical fractures from the lateral 2/3 of the condyle head with 0.5 (10 condyles) and 1mm (10 condyles) thickness were created using a fret saw. After creating condyle fractures, digital panoramic, LSP, and CBCT images were acquired. Two dentomaxillofacial radiologists with 15 years of experience, two dentomaxillofacial radiologists with five and seven years of experience, and two newly graduated dentists have evaluated the images. The success of the observers in diagnosing the vertical condyle fracture in each imaging method, intra-observer and inter-observer agreement was evaluated.

Results: The success of all dentists in determining the condyle fractures using LSP images was higher than the success they achieved using panoramic images, but it was not sufficient. Using different imaging options with CBCT, all diagnoses made by new graduates and dentomaxillofacial radiologists with five and 15 years’ experience were 100% compatible with the gold standard (AC1: 1 (1–1)).

Conclusions: For the diagnosis of vertical condyle fractures, conventional techniques (panoramic and lateral jaw imaging methods) were found to be insufficient.
Shockvertising como un método para promocionar el contenido de los servicios de transmisión de video bajo demanda
Authors: Brito-Rhor María Dolores , Velasco Vizcaíno Franklin , López Camila
Published: April 2021

Purpose: Most thumbnails promoting movies or series in video on demand (VOD) streaming services contain some form of shock advertising. The intention of this type of appeal is to bring immediate attention of viewers. However, little is known if shock advertising persuades consumers to watch series or movies on VOD streaming services such as Netflix or Amazon Prime Video. This study examines more deeply consumer responses to two types of shock advertising appeals: fetishism and sexual, and compares the results to an experimental condition in which there is an absence of shock advertising.

Design / Methodology / Approach: This study empirically tests if shock advertising, in the form of fetishism and sexual appeals, persuades consumers to watch series or movies. In the experimental setting, we manipulated romantic feelings and compared how each shock advertising types of appeals influence consumers when deciding what to watch in VOD streaming services. Analysis of variance was utilized to test the main effect of type of shock advertising appeal (fetishism vs. sexual vs. control condition) and to test the moderating effect of romantic feelings.

Results: Our findings suggest that consumers exposed to fetishism and sexual appeals revealed ower levels of persuasion compared to a control condition. An important finding of the study is the moderating effect of romanticism. When an individual has romantic feelings, conceived as a transitory mood state, the fetishism appeal becomes more persuasive than the sexual or the neutral appeals.

Limitations / Implications: These results are useful for improving the implementation of shock advertising appeals in the form of fetishism or sexual thumbnails for VOD streaming services. The study uses a single experiment to draw conclusions. Future research can test to generalize the results of this study in different settings.

Originality / Contribution: The main contributions derived from this research can be classified into two findings: it improves our understanding of consumer’s reactions to shock advertising; and, second advances our knowledge of the influence of positive emotions (romantic feelings) when consumers decide what to watch in video streaming services.

Purpose: Two studies were carried out. The main objective of study 1 was to find out the emotional effects and engagement that «GIFs» communication resources provoke in users. The main objective of study 2 was to determine the implicit attitudes that participants have towards well-known brands.

Design / Methodology /Approach: The first study uses a combination of biometric tools of automated observation of facial expressions, skin conductance and pupil direction to observe the emotional state that GIFs of well-known brands elicit in participants, and compare it to the effects caused by static images of the same brands.
The second study uses the Implicit Association Test to observe unconscious associations related to well-known brands.

Results: The results of the first study show that GIFs achieve user engagement and provoke a «feel-good-pleasure state» (Russel’s Circumplex Model, 1980), but not the expected enthusiastic state. The results of the second study indicate that participants have the belief that wellknown brands are quality brands, while they do not associate this attribute with non-famous brands. The correlation found between the results of the two studies reveals that GIFs, while provoking positive emotions and generating engagement, do not achieve an enthusiastic state when brands are internalised as quality brands.

Limitations / implications: The research method used has shown its usefulness in measuring user engagement in viewing GIFs using metrics such as the sign and intensity of emotion, and neuromarketing tools. The experimental study had its main limitation in not being able to observe the emotional effects generated by GIFs that allow user interaction.

Originality / contribution: Well-known brands, in addition to using these innovative visual resources, have to use them in a different way to generate surprise and manage to place potential customers in the «enthusiastic emotional state» of the Circumplex Model (Russel,1980).

Main topic subject: Advertising effectiveness or a way to measure the results of a communication campaign. Usually, results are understood as the repercussion or impact on a target audience. In other words, a campaign will be effective as long as it meets the objectives for which it was designed. The objectives are not always easy to determine and, consequently, to measure. In general, effectiveness is understood as the contribution to the development of the brand identity, the positioning of the product or service, differentiation in its competitive context and creating demand. The difficulty is to have a holistic measure that asseses all these aspects.

Logical development of the subject: A communication or campaign strategy cannot be limited to seeking superiority in indicators of a rational type such as contact and remembrance, with more or less level of knowledge (transmitting). This implies the risk that customers leave the brand if one day a competitor company surpasses said brand in the product or in the points of contact. It is advisable to move in the field of credibility and, to do so, campaigns must seek “authenticity” if they want to produce an effect or positive change in attitude and behavior towards what is said in it. The authenticity of a campaign is achieved when, in addition to being remembered and rationally associated with the brand or property, emotional ties are generated in the sense of connectivity.

Authors’ point of view and contributions: Communication Actions should seek more than just rational, static, one-way messages. They must seek a dialogue with the consumer to mark and create a series of emotional links that involve them with what they are seeing or feeling. When this occurs, it can be said that “the Action” is generating behavioral and prescription value. Only by being hyperconnected to the public, listening and speaking to them, is created a space of value and differential consumption against possible competition. In this case we will have overcome the value of use and transmitted the value that activates the decision of purchase and acquisition, predisposing to positive consumption experiences.

Implication and conclusions: If all of this occurs (to a greater or lesser degree), we will be able to say that the planned action has been effective. In this study, we present an empirical model for measuring authenticity in order to determine the level of effectiveness of a communication campaign or action.
The Working Mind

A general organismic-causal theory that explicates working memory and executive function developmentally, clarifying the nature of human intelligence.

In The Working Mind, Juan Pascual-Leone and Janice M. Johnson propose a general organismic-causal theory that explicates working memory and executive function developmentally and by doing so clarifies the nature of human intelligence. Pascual-Leone and Johnson explain “from within” (that is, from a subject's own processing perspective) cognitive developmental stages of growth, describing key causal factors that can account for the emergence of the working mind as a functional totality. Among these factors is a maturationally growing mental attention.

After reviewing meaning-driven processes and constructivist knowledge principles that underlie what Pascual-Leone and Johnson term their Theory of Constructive Operators (TCO), they propose the TCO as as a developmental and neuropsychological approach to human cognitive and affective processes and their development. They present a novel method of mental task analysis that generates from-within process models of subjects' attempts to solve specific tasks. They provide an interpretation of brain semiotic processes that deploys TCO in functionally distinct brain locations. Finally, they show how TCO explicates complex human issues including consciousness, the self, the will, motivation, and individual differences, with applications in education, psychotherapy, and cognitive neuropsychology.

Background:

Fatal Familial Insomnia (FFI) is a genetic prion disease caused by the D178N mutation in the prion protein gene (PRNP) in coupling phase with methionine at PRNP 129. In 2017, we have shown that the olfactory mucosa (OM) collected from FFI patients contained traces of PrPSc detectable by Protein Misfolding Cyclic Amplification (PMCA).

Methods:

In this work, we have challenged PMCA-generated products obtained from OM and brain homogenate of FFI patients in BvPrP-Tg407 transgenic mice expressing the bank vole prion protein to test their ability to induce prion pathology.

Results:

All inoculated mice developed mild spongiform changes, astroglial activation, and PrPSc deposition mainly affecting the thalamus. However, their neuropathological alterations were different from those found in the brain of BvPrP-Tg407 mice injected with raw FFI brain homogenate.

Conclusions:

Although with some experimental constraints, we show that PrPSc present in OM of FFI patients is potentially infectious.

Background

It is vital to cover wound management knowledge and operations in the early stages of resident training. With this in mind, a simulated wound management course for postgraduate year one surgery residents (PGY1s) was designed and its effectiveness was evaluated.

Methods

A retrospective quasi-experimental method was used. PGY1s in 2014 constituted the control group, and PGY1s in 2015 and 2016 constituted the intervention group. The course given to the control group comprised didactic teaching followed by deliberate practice plus immediate personalized feedback. The newly designed course given to the intervention group was reconstructed and disassembled into four components according to the simulation-based mastery learning model, which were baseline test, interactive learning, basic skills practice, and reflective learning. The same performance assessments were used in the control and intervention group, including process measurement and outcome measurement.

Results

The process measurement showed that the intervention group’s scores were significantly higher in the “dissociation of subcutaneous tissue” and “quality of suturing and knots”. The outcome measurement showed that the accuracy of debridement was greatly improved and both key and total suture numbers were significantly higher in the intervention group.

Conclusions

Simulation-based mastery learning was incorporated into our proposed course framework, promoting the learning outcome of PGY1s. It has the potential to be adapted for other surgical training sites for residents in China.
