Modification of a haematoxylin, eosin, and natural saffron staining method for the detection of connective tissue
Authors: Ceccopieri Cassandra , Skonieczna Joanna , Madej Jan P. 
Published: April 2021

Abstract

Introduction
The aim of our study was to optimise an existing staining procedure: haematoxylin-eosin saffron (HES). The method follows the classical haematoxylin and eosin protocol with the addition of a staining step using natural saffron to better identify the collagen fibres.

Material and Methods
The saffron solution was obtained by dissolving ground saffron stigmas in absolute alcohol. In order to test the HES method for its staining ability on four main types of collagen (I, II, III, and IV), specific tissues (skin, tooth, cartilage, aorta, spleen, and penis) were chosen.

Results
The procedure showed a sharp differentiation between muscle, stained red or pink, and connective tissue, stained bright yellow or orange.

Conclusion
HES allows the diagnosis of reticulin fibrosis undetected in HE and in previous saffron staining procedures. HES represents an advantageous alternative to HE staining giving highly reproducible results with high diagnostic value.
The impact of selected risk factors on the occurrence of highly pathogenic avian influenza in commercial poultry flocks in Poland
Authors: Gierak Anna , Śmietanka Krzysztof 
Published: April 2021

Abstract

Introduction
Introduction of highly pathogenic avian influenza virus (HPAIV) into a country and its further spread may have a devastating impact on the poultry industry and lead to serious economic consequences. Various risk factors may increase the probability of HPAI outbreak occurrence but their relative influence is often difficult to determine. The study evaluates how the densities of selected poultry species and proximity to the areas inhabited by wild birds impacted HPAI outbreak occurrence during the recently reported epidemics in Poland.

Material and methods
The analysis was developed using these risk factors in the locations of affected and randomly chosen unaffected commercial farms. Generalised linear and non-linear models, specifically logistic regression, classification tree and random forest, were used to indicate the most relevant risk factors, to quantify their association with HPAI outbreak occurrence, and to develop a map depicting spatial risk distribution.

Results
The most important risk factors comprised the densities of turkeys, geese and ducks. The abundance of these species of poultry in an area increased the probability of HPAI occurrence, and their farming intensity in several areas of central, western, eastern and northern Poland put these areas at the highest risk.

Conclusion
The results may improve the targeting of active surveillance, strengthen biosecurity in the areas at risk and contribute to early detection of HPAI in outbreak reoccurrences.

Abstract
More than 30 dog parasite species have been identified in Bosnia and Herzegovina so far, and half of these are zoonotic. The aim of the study was to investigate the occurrence of parasitic infections in dogs from Bosnian-podrinje canton with a focus on zoonotic parasites. The study included 212 dogs (107 owned and 105 stray). One or more of the twenty parasite species were found in 82.55% of tested samples. Dicrocoelium dendriticum (Class Trematoda) was found in 0.94% of dogs. Dipylidium caninum and Mesocestoides lineatus (Class Cestoda) were found in 7.55% and 0.94% of dogs, respectively. Taenia spp. and Echinococcus spp. (Family Taeniidae) were found in 0.47% and 0.94% of samples, respectively. In the family of Nematoda, the following parasite species were identified with corresponding percent among tested dogs: Toxocara canis (25.94%), Toxascaris leonine (8.96%), Strongyloides stercoralis (0.47%), Ancylostoma caninum (3.77%), Uncinaria stenocephala (52.36%), Trichuris vulpis (22.17%), Eucoleus aerophilus (1.42%), Dirofilaria immitis (1.89%) and Dirofilaria repens (1.42%). In the kingdom of Protozoa, the following parasite species were identified with corresponding percent among tested dogs: Cystoisospora canis (8.49%), C. ohioensis (2.36%), Cryptosporidium spp. (4.72%), Sarcocystis spp. (0.47%), Babesia spp. (5.19%), and Giardia duodenalis (15.57%). Leishmania infantum was not identified in tested samples. The results showed a high level of parasitic infestation in the dog population in the Bosnian-Podrinje canton, with a high occurrence of zoonotic parasites. Significant differences were found between owned and stray dogs for all classes of detected parasites with exception of the class Trematoda, disregarding specific parasite species.

Abstract
The aim of this study was to evaluate the effectiveness of imaging techniques (video-otoscopy-VO, radiography-RTG, computed tomography-CT) in diagnosing ear diseases in cats and dogs. Seven cats and thirteen dogs diagnosed with ear diseases were used for the research. Clinical examination, VO, RTG and CT were performed. Three (42.9%) unilateral otitis externa (OE), three (42.9%) unilateral otitis media (OM), and one (14.2%) bilateral otitis media (OM) with OE were diagnosed in 7 cats. Five (38.4%) unilateral OE, one (7.7%) unilateral OM, four (30.8%) bilateral OE, and three (23.1%) bilateral OM with OE were diagnosed in 13 dogs. All diagnostic methods were determined to be highly efficient for the specified diagnosis. VO and RTG were confirmed as sufficiently effective for the diagnosis of OE. OE plays a major role in the etiopathogenesis of OM, and for this reason, RTG and CT are required diagnostic methods for this condition.

Cultural Rights, Well-being and Democracy in Elderly Care: The Dance Ambassadors as a Case Study
Authors: Lehikoinen Kai 
Published: April 2021

Abstract
The aim of this article is to introduce how the Dance Ambassadors are perceived by nursing staff and supervisors in institutions of elderly care. The Dance Ambassadors are a dance-based service concept offered in various social contexts by the Dance Centre of Western Finland. Three central themes were identified in the perspectives of nursing staff: dance as a form of rehabilitation and support, dance as a contribution to a meaningful life, and participation in dance as a basic right. In the research, a multi-sited dance ethnographic approach was adopted to collect data. Then a thematic analysis was conducted in tandem with a descriptive-interpretative mixed methods approach to code and interpret the data. Social and theoretical frames as well as key concepts including cultural rights and cultural well-being are introduced in the article. In the discussion, some critical concerns are highlighted regarding the rehabilitation discourse in relation to dance in elderly care contexts and the unequal access to dance for people in late adulthood, which stands in stark contrast to the Constitution and its emphasis on human rights and equal treatment. Some suggestions are provided to improve the situation.
Subjectobject and Movementmaterial: A Diffractive Reading of the Becoming of Dance through the Subject
Authors: Yates Rebecca 
Published: April 2021

Abstract
With this study, which is linked to the research topic of ‘choreography’, I wish to contribute to our understanding of how internal and external factors are involved in the becoming of dance through the subject. I want to increase our understanding of the multilayered relationships that are ongoing in the becoming of dance and provide and develop understandings for didactical and pedagogical contexts. By studying my own praxis in a teaching context, I want to understand what is involved in the becoming of dance through the subject.
In the article, I use post-humanist theories, with an emphasis on materialists such as Rosi Braidotti and her concept of the nomadic subject. The nomadic subject is fundamental for this study because it uses materialistic understandings of the world without renouncing the subject’s previous situational experience and embodied knowledge. In addition to the nomadic subject, I use concepts such as diffraction, intra-action and agents. These concepts have their roots in the theories of Karen Barad, also a post-humanist.
I am interested in what agents are entangled in the process of becoming and what hierarchies are at work within my practice. I want to determine how they figurate and whether it is possible for these hierarchies to reach positions that are more anti-essential.
Silence in Aviation: Development and Validation of a Tool to Measure Reasons for Aircraft Maintenance Staff not Reporting
Authors: Under Ilker , Gerede Ender 
Published: April 2021

Abstract

Background and purpose: Organizational silence, seen as the greatest obstacle to the success of organizations and expressed as a refraining from expressing feelings, and ideas about problems encountered in their organizations, is identified as the avoidance of voluntary reporting in aviation organizations. The main purpose of this research is to identify and develop a tool to measure the various reasons for aviation employees’ remaining silent about the unsafe acts and events they witness, and the factors causing them to refrain from adopting safety enhancement proposals.

Methodology: Within the scope of the study, a data collection tool was developed. Explanatory and confirmatory factor analysis of the data obtained from 483 employees was conducted to test the reasons for not reporting voluntarily in aviation.

Results: As a result, it was found that employees did not participate in voluntary reporting due to factors of silence based on relational and prosocial factors, disengagement, quiescence and acquiescence, along with fear and defensiveness.

Conclusion: Accordingly, organizations need to acknowledge and act with the awareness that organizational silence is a common phenomenon. The importance of voluntary reporting should be explained to employees at every opportunity and the number of quality voluntary reports should be increased. However, this should go beyond the simple slogans of ‘Safety comes first in this workplace’ or ‘Safety first’ hanging on the wall of every organization.

Published: April 2021

Abstract

Background/Purpose: This work is focused on the variables that influence the outcomes of mergers and acquisitions, by learning from past mistakes, adopt better strategies and make wiser decisions to enhance the outcomes of their mergers and acquisitions. Using a qualitative approach, this research contributes to existing knowledge on mergers and acquisitions performance by exploring the cultural, managerial and organizational factors dimensions through an integrative approach using multiple perspectives.

Methodology: Fifteen interviews were conducted with experienced professionals in multiple areas of mergers and acquisitions. Content analysis was used to interpret the results. This enabled to achieve a more complete set of answers and potential solutions while comparing opinions on the same problems from slightly different angles.

Results: Results show the existence of managerial hubris, emotional attachment and over-optimism in mergers and acquisitions. There was a relative support towards standardizing the process of mergers and acquisitions deals, but respondents advise to keep some creativity and flexibility.

Conclusion: The article concludes by addressing key issues for mergers and acquisitions performance: capabilities and experience; organizational communication; internal coordination; and, key issues for decision-making.
Estimation of the excavator actual productivity at the construction site using video analysis
Authors: Šopić Martina , Vukomanović Mladen , Car-Pušić Diana , Završki Ivica 
Published: April 2021

Abstract
Current estimates of the actual productivity of heavy construction machinery at a construction site are not supported by an appropriate and widely used methodology. Recently, for the purpose of estimating the actual productivity of heavy construction machinery, vision-based technologies are used. This paper emphasizes the importance of estimating actual productivity and presents a way (i.e. a research framework) to achieve it. Therefore, the aim of this paper is to propose a simple research framework (SRF) for quick and practical estimates of excavator actual productivity and cycle time at a construction site. The excavator actual productivity refers to the maximum possible productivity in real construction site conditions. The SRF includes the use of a video camera and the analysis of recorded videos using an advanced computer program. In cases of continuous application of SRF, a clear and transparent base for monitoring and control of earthworks can be obtained at an observed construction site.
On-site factories to support lean principles and industrialized construction
Authors: Rosarius Anton , García de Soto Borja 
Published: April 2021

Abstract

Purpose
The purpose of this study is to investigate the use of on-site factories that combine the strengths of both prefabrication techniques and a traditional work environment to support lean principles and promote industrialized construction for on-site operations.

Design/methodology/approach
Based on the principles of lean construction and design for manufacturing and assembly (DfMA), discrete-event simulation is used to evaluate different arrangements and configurations of an on-site factory for the prefabrication of structural insulated panels (SIPs).

Findings
The proposed on-site factory provided a feasible way to promote lean and industrialized construction principles. Also, these types of factories are particularly relevant for projects in remote areas that do not have sufficient infrastructure. Further, it is also a good solution for strengthening the local economy by using local labor and suppliers, hence assisting in the creation of a socially responsible framework.

Originality/value
This study presents the design of an on-site factory for the prefabrication of SIPs. This type of on-site assembly supports not only lean principles but also promotes social responsibility by capitalizing on local labor. This approach could be particularly interesting for construction companies in developing countries or working in a project with limited infrastructure.

The authors discuss the effects of applying the adopted methodological solutions. Some of them present a new approach to cartographic visualisation of spatial data. It may be an opportunity to look at various visualisation methods, their effectiveness, and the possibility of visualising nature issues on small-scale thematic maps.
Applying a Newly Learned Second Language Dimension to the Unknown: The Influence of Second Language Mandarin Tones on the Naïve Perception of Thai Tones
Authors: Schaefer Vance , Darcy Isabelle 
Published: April 2021

Abstract
This study investigates whether L2 Mandarin learners can generalize experience with Mandarin tones to unfamiliar tones (i.e., Thai). Three language groups – L1 English/ L2 Mandarin learners (n=18), L1 Mandarin speakers (n=30), L1 monolingual English speakers (n=23) – were tested on the perception of unfamiliar Thai tones on ABX tasks. L2 Mandarin learners and L1 Mandarin speakers perceived Thai tones more accurately than L1 English non-learners. Mandarin learners L1 speakers showed priming on Mandarin tones on a lexical decision task with repetition priming, suggesting L2 tones had been encoded within lexical representations of L2 Mandarin words. However, results must be interpreted cautiously, with an absence of expected priming and presence of unexpected priming. In sum, learners can transfer L2 tone experience to unfamiliar tones, expanding the Feature Hypothesis (McAllister, Flege, & Piske, 2002) to include L2 influence as well. In addition, results indicate a potential disconnect between perception and encoding.
Automated Extraction and Presentation of Data Practices in Privacy Policies
Authors: Bui Duc , Shin Kang G. , Choi Jong-Min , Shin Junbum 
Published: April 2021

AbstractPrivacy policies are documents required by law and regulations that notify users of the collection, use, and sharing of their personal information on services or applications. While the extraction of personal data objects and their usage thereon is one of the fundamental steps in their automated analysis, it remains challenging due to the complex policy statements written in legal (vague) language. Prior work is limited by small/generated datasets and manually created rules. We formulate the extraction of fine-grained personal data phrases and the corresponding data collection or sharing practices as a sequence-labeling problem that can be solved by an entity-recognition model. We create a large dataset with 4.1k sentences (97k tokens) and 2.6k annotated fine-grained data practices from 30 real-world privacy policies to train and evaluate neural networks. We present a fully automated system, called PI-Extract, which accurately extracts privacy practices by a neural model and outperforms, by a large margin, strong rule-based baselines. We conduct a user study on the effects of data practice annotation which highlights and describes the data practices extracted by PI-Extract to help users better understand privacy-policy documents. Our experimental evaluation results show that the annotation significantly improves the users’ reading comprehension of policy texts, as indicated by a 26.6% increase in the average total reading score.
Efficient homomorphic evaluation of k-NN classifiers
Authors: Zuber Martin , Sirdey Renaud 
Published: April 2021

Abstract
We design and implement an efficient, secure, homomorphic k-Nearest Neighbours determination algorithm, to be used for regression or classification over private data. Our algorithm runs in quadratic complexity with regard to the size of the database but is the only one in the literature to make the secure determination completely non-interactively. We show that our secure algorithm is both efficient and accurate when applied to classification problems requiring a small set of model vectors, and still scales to larger sets of model vectors with high accuracy yet at greater (sequential) computational costs.

Published: April 2021

Abstract
Sprouts of diploid red clover ‘Stendes Agrais’ were treated with 0.2% colchicine solution. The ploidy level of plants was detected by flow cytometry. Most of the treated plants were mixoploids and sterile. From progenies of fertile plants, mixoploids were selected that had a proportion of tetraploid cells higher than 60%. In the next generation, stable tetraploid plants were selected, and 49 lines were included in the breeding process.

Authors: Volavc Tajda Srot , Rupreht Mitja 
Published: April 2021

Abstract

Introduction
The aim of the study was to review the appearances of Morel-Lavallée (ML) lesions on magnetic resonance imaging (MRI).

Patients and methods
14 patients diagnosed with the ML lesion on MRI were analysed retrospectively (mean age = 35 years). Mechanism of injury, time frame from injury to MRI, location, shape, T1 and proton-density fat-suppression (PDFS) signal intensity (SI), presence of a (pseudo)capsule, septations or nodules within the collection, mass effect and fluid-fluid levels were analyzed. The Mellado and Bencardino classification was utilized to classify the lesions.

Results
In most cases, mechanism of injury was distortion. Mean time frame between the injury and MRI was 17 days. Lesions were located around the knee in 9 patients and in the peritrochanteric region in 5 patients. Collections were fusiform in 12 patients and oval in 2 patients. 9 collections were T1 hypointense and PDFS hyperintense. 4 collections had intermediate T1 and high PDFS SI. 1 collection had intermediate T1 and PDFS SI. (Pseudo)capsule was noted in 3 cases. Septations or nodules were found in 4 cases. According to the Mellado and Bencardino, collections were classified as seroma (type 1) in 9, subacute hematoma (type 2) in 1 and chronic organizing hematoma (type 3) in 4 cases.

Conclusions
Characteristic features of ML lesion include a fusiform fluid collection between the subcutaneous fat and the underlying fascia after shearing injury. Six types can be differentiated on MRI, with the seroma, the subacute hematoma and the chronic organizing hematoma being the commonest.
Impact of coronary artery tortuosity in ischemic and non-ischemic cardiovascular pathology
Authors: Mihai Dumitru Emilian , Lupasteanu Ioana , Dan Gheorghe Andrei 
Published: April 2021

Abstract
The aim of this paper was to review based on the existing literature the impact of coronary artery tortuosity on coronary pathology. Primarily, an attempt was made to establish the implication of coronary tortuosity as a physio-pathological mechanism of inducing ischemia in patients with non-obstructive coronary artery disease (CAD). Because the prevalence of tortuosity is higher in severe hypertensive patients, a second purpose of this paper was to review this association by understanding the physio-pathological processes and fluid dynamics in hypertrophic heart. Particularly, the effect of coronary tortuosity on systolic function with reference to longitudinal function and ventricular relaxation was addressed. Finally, the technical difficulties imposed by coronary tortuosity to percutaneous coronary interventions were discussed.
