Cognitive Biases in Negotiation - Literature Review
Authors: Chmielecki Michał
Published: July 2020

Objective: The purpose of this paper is also to thoroughly review those studies in the management literature that focused on bias in negotiation and to ascertain a couple of new research trajectories that could be observed as the result. As a matter of fact, a human’s judgment making capacity and behavior could be greatly influenced by cognitive misperceptions thus affecting decisions in negotiations. Whilst Thompson (2006) analytically examined the effects of biased decision-making processes for negotiations, the intention of this paper is to fill the gap through a systematic assessment of the literature.

Methodology: I have provided a theoretical background on decision makers’ cognition in this paper to provide context and introduce the research; after which we take a closer look at the literature and discuss its results. Based on this, I noted that limited research, with alternate results were done based on the interaction between biases bothering on mood, culture, personality as well as education and experience on the negotiators’ judgments. Finally, we suggest that future research trajectories might be on multilateral and integrative negotiations, the role of third parties and a better comprehension of the cognitive bias and how to rise above it in negotiations.

Findings: Despite the fact that this topic is considered important, it is surprisingly under-researched. Author was able to identify the void and inadequacies of the literature identified in journal articles systemizing the intersection of negotiation studies, from cognitive biases studies, group decision making and from the decision making and judgment literature.

Value Added: This paper showed that there are only a handful of papers that focus on why, how and when cognitive biases influence negotiation process.

Recommendations: There is a great need for papers that focus on cognitive biases in the negotiation process.
The Willingness to Employ Immigrants in Polish Organizations
Authors: Maj Jolanta , Kubiciel-Lodzińska Sabina , Widera Katarzyna
Published: July 2020

Objective: For a long time Poland has been perceived as a rather homogenous society. However, cultural diversity and differences started to become visible after 1989 and have gained on importance since then. Combined with an increasing shortage of native workforce, the question of immigrants’ employment by Polish organisations becomes a burning issue. We have therefore decided to determine whether the fact of employing immigrants or the intention to do so in the foreseeable future affects the perception of foreign workers and the necessity of hiring them

Methodology: For this purpose, we conducted a survey among 263 entrepreneurs from the Opolskie Voivodship.

Findings: The study has demonstrated a very strong, statistically-relevant correlation between the willingness to employ immigrants and the attitude towards an employee’s country of origin. Also correlations between other analysed variables have been found statistically relevant

Value Added: The paper is an introduction to a debate on the role of immigrants on the Polish labour-market as it presents the point-of view of employers and their willingness to employ immigrants.

Recommendations: It is recommended for decision-makers to facilitate access of a wider group of immigrants to the Polish labour market, especially since a significant group of employees recognises the upcoming issue of workforce shortages and the necessity to reach for foreign employees in order to stay competitive.

Authors: Śmiałek Marcin , Tykałowski Bartłomiej , Dziewulska Daria , Kowalczyk Joanna , Koncicki Andrzej
Published: July 2020

Introduction

Despite vaccination against avian metapneumoviruses (aMPV), cases of turkey rhinotracheitis (TRT) caused by aMPV field strains are frequently reported. Differences have been shown in the level of immune system stimulation after aMPV vaccination between turkeys that do and do not possess specific anti-aMPV maternally derived antibodies (MDA). The article describes the influence of MDA on the production of IFNγ in the spleen of aMPV-vaccinated turkeys.

Material and Methods

MDA+ or MDA− turkeys were vaccinated against TRT after hatching or on the 14th day of life. Spleen samples were collected 3, 7, and 14 days post vaccination for mononuclear cell isolation. Real-time PCR, flow cytometry, and the enzyme-linked immunospot assay were used to evaluate the levels of IFNγ gene expression, production, and secretion by cells within the spleen samples.

Results

Increased IFNγ gene expression was noticed after vaccination only in birds that did not possess MDA or possessed MDA at relatively low level (MDA+ birds vaccinated at 14 DOL). In all birds, an increased percentage of T lymphocytes producing IFNγ was recorded. The proportion of anti-aMPV IFNγ-secreting cells was increased only in MDA− birds.

Conclusion

Besides having a protective role, MDA are known to interfere with vaccination efficacy. The analysis of our results confirms that MDA can decrease the level of immune system stimulation after aMPV vaccination of turkeys.

Published: July 2020

There are more than 24.1 % of the world’s population are Muslim. Considering the religious preference, Drug Control Authority (DCA) requires manufacturers to declare clearly if their products contain materials of animal origin, as well as unsafe drugs. In general, Health supplements, herbal products, and traditional medicine are classified as “food-drug interphase (FDI) products. FDI products are products with a combination of food ingredients and active ingredients for oral consumption. FDI products are widely believed to be able to prevent or even cure many diseases. However, over the past ten years, there are various FDI products in Malaysia contain dangerous drugs. Hence, this study summarizes the harmful effect of listed unsafe drugs possess in the FDI products, the category of the product, and the type of claim. According to the National Pharmaceutical Regulatory Agency (NPRA) recent report, there are 162 FDI products have been mixed up with illegal drugs which majority of them contain Dexamethasone. The most category of products that contain unsafe drugs is among traditional medicine products followed by health supplements, herbal supplement products, and dietary supplements. These products were commonly marketed to strengthen the veins & joint and pain relief, weight loss, sexual enhancement, energy booster, relieve sinus, and gout. Hence, an awareness of adulteration in pharmaceuticals is crucial to ensure the quality, safety, and effectiveness of the products towards human health.

Authors: Bratianu Constantin , Prelipcean Gabriela , Bejinaru Ruxandra
Published: July 2020

The purpose of this paper is to explore the latent variables which support small and medium-sized enterprises (SMEs) in becoming learning organizations. These latent variables represent abstract ideas that cannot be measured directly in practice, and they need to be explored by using different sets of other variables or indicators defined specifically for certain research of the business environment. The concept of “the learning organization” has been introduced into knowledge management literature about 30 years ago, but due to its complexity and high level of abstractness, its implementation in real life or organizations produced insufficient results for developing a well-defined model and a convincing managerial approach. However, the attractiveness of the learning organization is so appealing that researchers continue to investigate the complex mechanisms and processes supporting it. Our research is such an effort in exploring the latent variables for the small and medium-sized enterprises from the North-Easter region of Romania in their drive of becoming learning organizations. Our research is based on a comprehensive literature search and a quantitative approach supported by a survey and statistical processing of the collected data. We processed 950 valid questionnaires obtained from 147 small and medium-sized enterprises from the North-Eastern region of Romania. Statistical processing was done by using specialized software. We perform a Factor Analysis with IBM SPSS v.19, and then a Confirmatory Factor Analysis with AMOS v.18. Finally, we obtained six latent variables that support the transformation of SMEs into learning organizations.

Authors: Olszewski Jerzy , Walczak Katarzyna
Published: July 2020

The presence of uranium makes the Kowary area characterized by an increased concentration of radon in the air and the living houses. Measurements of periodic radon concentrations in dwellings of Kowary were carried out three times in the last 20 years. It can be observed that 20 years ago level of radon concentrations in houses of Kowary were lower than today. Measurements carried out in Kowary over 20 years have shown that residents are exposed to radon concentrations, which often exceed 300 Bq m−3 – a reference level recommended by the European Union. The present geometric mean of radon concentration in houses of Kowary (260 Bq m−3) exceeds the geometric mean of radon concentration of buildings in the rest of Poland (142 Bq m−3).

Published: July 2020

The increasing population growth and urbanization rises the worldwide consumption of material resources and energy demand. The challenges of the future will be to provide sufficient resources and to minimize the continual amount of waste and energy demand. For the achievement of sustainability, increasing recycling rates and reuse of materials, next to the reduction of energy consumption has the highest priority.

This article presents the results of the multidisciplinary research project SCI_BIM, which is conducted on an occupied existing building. Within SCI_BIM, a workflow for coupling digital technologies for scanning and modeling of buildings is developed. Laser scanning is used for capturing the geometry, and ground-penetrating radar is used for assessing material composition. For the semi-automated generation of an as-built BIM, algorithms are developed, wherefore the Point-Cloud serves as a basis. The BIM-model is used for energy modeling and analysis as well as for the automated compilation of Material Passports. Further, a gamification concept will be developed to motivate the buildings’ users to collect data. By applying the gamification concept, the reduction of energy consumption together with an automated update of the as-built BIM will be tested. This article aims to analyze the complex interdisciplinary interactions, data, and model exchange processes of various disciplines collaborating within SCI_BIM.

Results show that the developed methodology is confronted with many challenges. Nevertheless, it has the potential to serve as a basis for the creation of secondary raw materials cadaster and for the optimization of energy consumption in existing buildings.

Authors: Ceric Anita , Ivic Ivona
Published: July 2020

The construction labor is crucial to the construction industry, which is known globally for its creation of jobs at different skill and professional levels. The world's construction industry is currently experiencing a rapid recovery after the 2008 global crisis. This positive growth is also noticeable in Croatia. Nevertheless, the industry is experiencing a considerable shortage of skilled labor. First, this paper investigates the main causes of the current condition of the labor market through an extensive literature review and construction market analysis. Second, the case study of the Croatian construction labor market is presented. The longitudinal study of official statistical data shows that the total number of workers employed over the last 10 years has decreased significantly. There has been an increase in the number of unskilled workers and a decrease in the number of all other types of workers between 2016 and 2017. Following the literature review and market analysis, the response strategies for the problem of labor shortage in Croatian construction are provided and discussed.

Authors: Ahmed Zahoor , Khan Abdul Salam , Ahmed Bilal
Published: July 2020

The Oligocene-Early Miocene Nari Formation is widely distributed in the Kirthar thrust-fold belt. The formation in the study area is mainly consist of sandstone and shale. Field observations and detailed petrographic study reveal that these sandstones are mostly fine to medium grained, subangular to subrounded and poorly to moderately sorted. Detrital grains are dominantly quartz ranging in proportion 36-76%, feldspar 7-17% and lithic grains 1-13%, reflecting that these sandstones are compositionally submature. Quartz is mostly monocrystalline with some polycrystalline grains. Feldspar is dominantly plagioclase (albite) with some alkali feldspar (orthoclase and microcline). Lithic fragments are siltstone, mudstone and chert. Biotite and muscovite are present as accessory minerals. Heavy minerals such as apatite, tourmaline, and zircon are present in trace amount. The QFL diagrams show that the sandstones of the Nari formation are subarkose and lithic subarkose. The QtFL, QmFLt ternary diagrams and paleocurrent direction suggest that the sediments were transported from the Indian shield exposed to the northeast of the Nari Basin.

Authors: Khorasani Amir
Published: July 2020

Introduction: irreversible electroporation (IRE) is a tissue ablation technique and physical process used to kill the undesirable cells. In the IRE process by mathematical modelling we can calculate the cell kill probability and distribution inside the tissue. The purpose of the study is to determine the influence of electric conductivity change in the IRE process into the cell kill probability and distribution.

Methods: cell death probability and electric conductivity were calculated with COMSOL Multiphysics software package. 8 pulses with a frequency of 1 Hz, pulse width of 100 µs and electric field intensity from 1000 to 3000 V/Cm with steps of 500 V/Cm used as electric pulses.

Results: significantly, the electrical conductivity of tissue will increase during the time of pulse delivery. According to our results, electrical conductivity increased with an electric field intensity of pulses. By considering the effect of conductivity change on cell kill probability, the cell kill probability and distribution will change.

Conclusion: we believe that considering the impact of electric conductivity change on the cell kill probability will improve the accuracy of treatment outcome in the clinic for treatment with IRE.
Radiological and health hazards resulting from radioactivity and elemental composition of some soil samples
Authors: Al-Khawlany Abdu Hamoud , Khan A. R. , Pathan J. M.
Published: July 2020

Inspection of the radioactivity level in the soil is very important for human health and environmental protection. This study aims at evaluating the radiological hazards and pollution risks related to natural radionuclides and elements in the selected soil samples. Ten samples of soil were collected from different sites of Aurangabad-India and the level of radioactivity was measured using gamma-ray spectrometry with NaI (Tl) detector. Furthermore, the Physico-chemical properties such as pH, organic matter, electrical conductivity, moisture, soil texture, etc., and elemental composition of soils have been decided on using various standard techniques. The mean concentrations of 226Ra, 232Th, and 40K were 8.178, 17.408, and 96.496 Bq/kg, respectively, which are lower than the global average values of 35, 30, and 400 Bq/kg, respectively (UNSCEAR, 2000). The radiological hazard indices such as radium equivalent, absorbed dose, annual effective dose, internal index, external index, gamma index, excess lifetime cancer risk, etc., were calculated to assess the radiation hazards and compared with internationally recommended values which found to be lower than the permissibility limits.

The Pearson correlation was applied to determine the existing relationship between radionuclides and radiological health hazard parameters, as well as with the physicochemical properties of the soil samples. The major and trace elements presented in soils were measured and their mean concentration was ranked in the formed order (Mg>Na>Ca>K>N>Mn>Fe>P>Zn>Cu). The pollution risk parameters (Geo-accumulation index, contamination factor, degree of contamination, pollution load index, and potential ecological risk index) related to the elements in the samples were assessed and results shown that the soils under study are unpolluted with the measured elements. Generally, the radioactivity levels and pollution risks indices in the soils of the study area are within the permissible safety limits and do not cause any significant health threat to humans. Thus, the presented data provide a general background of the detectable radionuclides for the study area and can be helpful in the future as a reference for more extensive studies in the same field.

Erinnerungspolitik und Medialisierung von DDR-Geschichte. Plädoyer für eine andere Wahrnehmung1
Authors: Hähnel-Mesnard Carola
Published: July 2020

Der Beitrag hinterfragt die Konstruktion und Vermittlung der Erinnerung an die DDR. Gegenwärtig ist die Interpretation der DDR-Geschichte in den Medien, in den meisten staatlichen Museen sowie in erfolgreichen Kinoproduktionen immer noch stark durch das totalitaristische Paradigma geprägt. Diese Darstellung steht im Widerspruch zur Alltagswahrnehmung der meisten ehemaligen DDR-Bürger. Obwohl sich die Forschung seit langem für Aspekte der Alltagsgeschichte interessiert, sind solche Elemente in den meisten aktuellen Darstellungen der DDR kaum vorhanden. Andreas Dresens und Laila Stielers Film Gundermann (2018) ist ein Beispiel für den Versuch von Ostdeutschen, die Deutungshoheit über ihre Geschichte zurückzugewinnen. Insgesamt beeinflusst die Unterrepräsentation der Ostdeutschen in Schlüsselpositionen der Gesellschaft auch die Möglichkeiten, auf die öffentlichen Erinnerungsprozesse Einfluss zu nehmen.
The Use of the Collocation Algorithm for Estimating the Deformations of Soil-Shell Objects Made of Corrugated Sheets
Authors: Machelski Czesław
Published: July 2020

The algorithm presented in this paper is intended for the analysis of deformations of shells in the construction phase of soil-shell objects when strain gauges and geodetic measurements are used. During the construction of such an object, large displacement values occur and the impact of axial forces on the displacement of a corrugated metal sheet is small. Internal forces (strain gauges), as well as the displacements of a selected circumferential band of the shell are determined directly from such observations.

The paper presents two examples of the analysis of large span shell structures of constructed objects, as well as the assessment of the effectiveness of the finite difference method (FDM) in beam schemes. Good deformation mapping was indicated using the collocation algorithm and the differential approach to the solution when there is a dense mesh and regular distribution of measuring points. In the analysed examples, a significant divergence between the support conditions adopted in the FEM calculation models and the actual static conditions in the objects was indicated. The collocation algorithm is especially designed for such situations. Collocation points in such a solution are used to consider a beam – separated from a structure and without boundary constraints, but with specific changes in curvature – as a reference system, which is determined from the geodetic measurements of two collocation points.
Vibrations of the Euler–Bernoulli Beam Under a Moving Force based on Various Versions of Gradient Nonlocal Elasticity Theory: Application in Nanomechanics
Authors: Paweł Śniady , Misiurek Katarzyna , Szyłko-Bigus Olga , Rafał Idzikowski
Published: July 2020

Two models of vibrations of the Euler–Bernoulli beam under a moving force, based on two different versions of the nonlocal gradient theory of elasticity, namely, the Eringen model, in which the strain is a function of stress gradient, and the nonlocal model, in which the stress is a function of strains gradient, were studied and compared. A dynamic response of a finite, simply supported beam under a moving force was evaluated. The force is moving along the beam with a constant velocity. Particular solutions in the form of an infinite series and some solutions in a closed form as well as the numerical results were presented.

Published: July 2020

Although fiber-reinforced polymers (FRPs) have achieved increasing popularity in strengthening concrete structures and reinforcing new ones, there is to date insufficient knowledge about their long-term behavior. The long-term properties of FRPs specified in design codes lead to the low utilization capacity of these materials and are not supposed to be correct according to the actual behavior of structures reinforced with FRPs after 20 or 30 years of their use. Environmental impact reduction factors limit the mechanical properties of FRP composites in a range from 0.95 for CFRP to 0.5 for GFRP; the creep rupture factor is from 0.9 to 0.2. The paper summarizes previous research and experimental studies on the long-term properties of FRP reinforcements and also their comparison with the actual structures in which this reinforcement has been used; it presents the first part of an experimental investigation with comparative calculations.

Authors: Lorber Mateja , Treven Sonja , Mumel Damijan
Published: July 2020

Introduction

Well-being is one of the most important factors in whether nurses decide to remain in the nursing profession. This study aims to examine well-being and satisfaction among nurses working in Slovenian hospitals and to identify the related demographic factors.

Methods

This descriptive cross-sectional study uses standardised instruments. The sample included 640 nurses working in Slovenian hospitals. The difference between individual variables were analysed using the Mann-Whitney and Kruskal-Wallis tests.

Results

Nurses self-assessed their satisfaction and well-being as moderate. Forty-seven per cent of nurses were satisfied with their job, 49% assessed their psychological well-being as good, 52% were often exposed to stress at the workplace and 30% were always exposed to stress at the workplace. Levels of job satisfaction (p=0.031), psychological well-being (p=0.029) and subjective well-being (p=0.014) were found to differ significantly according to level of education, while levels of job satisfaction (p=0.005), life satisfaction (p<0.001), psychological well-being (p<0.001) and subjective well-being (p<0.001) were also found to differ according to years of nursing service and from hospital to hospital (p<0.001).

Conclusions

The key finding of the study is that nurses are moderately satisfied with their work and life and that they display moderate levels of psychological and subjective well-being. Hospitals can be successful and achieve the goals of the organisation if their employees are satisfied with work and enjoy good levels of well-being. Hospital management have to recognise the importance of ensuring that nurses and other employees are satisfied and healthy.
Interaction Between Consumers and Emerging forms of Artificial Intelligence: A Discriminant Analysis
Authors: Pelău Corina , Ene Irina
Published: July 2020

The interaction between consumers and companies has been changed because of the development and implementation of artificial intelligence. On one hand, the implementation of artificial intelligence systems increases the efficiency and rapidity of certain processes, by making the life of consumers and companies easier. On the other hand, their implementation brings certain challenges because of the changes it involves, including the acceptance of artificial intelligence systems by the consumers, the ability to learn how to operate the robots as well as the protection of the information gathered by these systems. In this paper, we aim to measure the acceptance of consumers regarding different forms of artificial intelligence systems. By applying a discriminant analysis, we measure the preference of consumers towards human versus robot interaction as well as between different types of robots with different forms and degrees of anthropomorphic characteristics. The results show that consumers prefer human interaction to the interaction with robots, especially in cases where they are not familiar with the robot interaction. Besides, they prefer the communication to classic robots in comparison to human holograms and they have a certain curiosity towards humanoid robots in opposition to classic robots.

Published: July 2020

Modern societies are built on good road infra-structure and efficient transport system. Safety is a high-priority consideration in development of road traffic systems. In recent years the weather information has become becomes very vital for road traffic safety because slippery roads are the key source of road accidents in northern regions of Europe, America and Canada as well. In this article we are presenting the test experiences and pilot road weather related services by executing a set of Vehicle to Infrastructure (V2I) communication scenarios by using IEEE 802.11p and 5G test networks. We have made an effort to evaluate the performance of IEEE 802.11p and 3GPP (3rd Generation Partnership Project) 5G test network. We also analyzed the performance of IEEE 802.11p with and without safety feature for secure and reliable vehicular communication. The combination of IEEE 802.11p with 5G test network cellular network makes the traffic system heterogeneous for traffic safety. This heterogeneous system provides the opportunity to exploit the vehicle-based actuators, sensor, and observation data in order to produce the intelligent service platform and up-to-date real time services for vehicles.

In this article we have also made a comparison by using an IEEE 802.11p system having safety feature of SafeCOP (Safe Co-operating Cyber-Physical Systems using Wireless Communication) project. SafeCOP is a European project that aims cyber-physical systems-of-systems relying on wireless communication for safe and secure cooperation. This safety feature will help to decrease the amount of road accidents (Car crashes, injuries and fatalities) by offering safe and secure V2V and V2I co-operation. The fundamental advantage of this kind of performance analysis is that the communication between Vehicle-to-Road Weather station (V2RWS) can be exchanged safely and reliably, at the cost of network resources consumed by a safety feature in IEEE 802.11p. It’s clearly presented in this paper, that the use of heterogeneous network and SafeCOP feature for vehicular networking has a clear potential in near future for vehicle’s safety and security of vehicular network.

Published: July 2020

The ever-increasing tendency of people to travel by motorized vehicles contributes significantly to air pollution and traffic problems. Active travel, namely walking and cycling, seems to be a feasible solution to the current situation in urban mobility. The present paper aims at investigating the effects of active travel in health and quality of life and determine those factors that affect travel behavior. A structured literature review was carried out, which revealed the strong association of walking/cycling with the containment of noncommunicable diseases and the invigoration of wellbeing and self-confidence. In addition, a questionnaire survey was conducted in Greece, addressing the attitudes and perceptions of 507 people towards active travel, health and quality of life. Results showed that participants have a more positive attitude about walking compared to cycling, while characteristics such as age, gender, body mass index, physical and health conditions determine active commuting and consequently life satisfaction.

Authors: Mironov Alexey V. , Umakhanova Madina M. , Zhukocky Alexandr V.
Published: July 2020

Relevance. Endothelial pathology is an important factor in the development of obstetric complications. Endothelial dysfunction means a violation of vascular homeostasis and leads to critical changes in the microcirculatory system. These changes in early pregnancy disrupt the processes of trophoblast invasion, determining obstetric complications.
Aim. To improve the diagnosis of fetoplacental system disorders by examining endothelial function in the first trimester of pregnancy.
Materials and methods. 180 pregnant women in the first trimester were examined: 90 women who were diagnosed with a failed miscarriage and had an instrumental removal of the fetal egg, as well as 90 somatically healthy pregnant women who had an instrumental abortion at will. Endothelial status was diagnosed in the groups: concentrations of C-reactive protein, von Willebrand factor and apoptosis protein p53 in serum, albumin in urine were determined, and desquamated endothelial cells were counted in peripheral blood. After instrumental removal of the fetal egg in all pregnant women studied, morphometry of fetal chorion vessels was performed: the average wall thickness of the primary vessel, the average diameter of the vessel lumen, the average area of the vessel lumen, and the Kernohan index were determined. The obtained results were subjected to statistical analysis.
Conclusions. The study of endothelial function in the first trimester of pregnancy can be used as a test for detecting vascular disorders in pregnant women, being an important criterion for early diagnosis of obstetric complications.

Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.
Loss of polycystins suppresses deciliation via the activation of the centrosomal integrity pathway
Authors: Gerakopoulos Vasileios , Ngo Peter , Tsiokas Leonidas
Published: July 2020

The primary cilium is a microtubule-based, antenna-like organelle housing several signaling pathways. It follows a cyclic pattern of assembly and deciliation (disassembly and/or shedding), as cells exit and re-enter the cell cycle, respectively. In general, primary cilia loss leads to kidney cystogenesis. However, in animal models of autosomal dominant polycystic kidney disease, a major disease caused by mutations in thepolycystingenes (Pkd1orPkd2), primary cilia ablation or acceleration of deciliation suppresses cystic growth, whereas deceleration of deciliation enhances cystogenesis. Here, we show that deciliation is delayed in the cystic epithelium of a mouse model of postnatal deletion ofPkd1and inPkd1- orPkd2-null cells in culture. Mechanistic experiments show that PKD1 depletion activates the centrosomal integrity/mitotic surveillance pathway involving 53BP1, USP28, and p53 leading to a delay in deciliation. Reduced deciliation rate causes prolonged activation of cilia-based signaling pathways that could promote cystic growth. Our study links polycystins to cilia dynamics, identifies cellular deciliation downstream of the centrosomal integrity pathway, and helps explain pro-cystic effects of primary cilia in autosomal dominant polycystic kidney disease.

Purpose: Corporate governance and capital structure are seen as significant factors in improving corporate performance. Although many studies have examined the association among corporate governance and capital structure through company performance, this type of research remains still scarce in the Malaysian context. The purpose of this research is to advance a conceptual framework that observes the effect of corporate governance and capital structure on the performance of public firms in Malaysia.
Design/Methodology/Approach: The research used secondary data using annual reports of companies registered on Bursa Malaysia from the period 2013 to 2016. The data was captured from Thomson Reuters Data Stream Version 5.1 available at the Sultanah Bahiyah Library of Universiti Utara Malaysia.
Implications/Originality/Value: This research proposes to enhance the role of corporate governance and capital structure, and to redefine corporate governance policy and capital structure to enhance corporate performance. Finally, it is hoped that this research will increase the performance of the company, and benefit the financial report users, investors, creditors, shareholders, and other stakeholders in public companies in Malaysia.

The article highlights the proposed algorithm for evaluating the reliability of steel frames. In particular, it is possible to analyze the reliability of the most likely failure mechanism. Separate assumptions that determine the sequence of application ofthe limit equilibrium method are presented. A method for determining the reliability of statically indeterminate steel framesin the plastic stage is presented. This method provides an opportunity to determine the probable mechanism of destruction.The ultimate equilibrium method is used to calculate the forces at the final stage of destruction. In the work, the real mechanism of destruction is understood as a mechanism for which the work of external forces to create it is the least. It is revealedthat the real mechanism of destruction is approaching the beam or floor elementary mechanism.

The peculiarities of biogas technology application in the falling leaves utilization plants are analyzed and the application ofsoil cement is proposed to create the basic elements of such plants. A new schematic and constructive solution of biogasfermenter (bioreactor) with application of soil-cement technology with a blending method for efficient functioning oftechnological chain of biogas fermentation of fallen leaves and other plant residues for energy supply systems has beendeveloped. The possibility of reliable isolation of the space of the bioreactor to the excavation of the pit from the surroundingarray with soil cement screen is substantiated. The corrosion resistance of the soil cement waterproof screen has been proved.

This study was conducted as anin vivoexperiment in adult miniature pigs with the aim to test two new biomaterials. An iatrogenic defect was made into the central femoral diaphysis in the experimental animals and subsequently fixated by bridging plate osteosynthesis. Into the defect we implanted a cancellous autograft (control group), a pasty injectable scaffold (EXP A), and a porous 3D cylinder (EXP B). Radiological examination was performed in all animals at 0, 10, 20, 30 weeks after surgical procedure and histological assessment was performed. In the newly formed bone the osteoblastic activity was monitored. In terms of radiology, the most effective method was observed in the control group (completely healed 100%) compared to experimental groups EXP A (70.0%) and EXP B (62.5%). Histological assessment showed a higher cell count in the place of bone defect in the control group compared to experimental groups. Between the experimental groups, a higher count of bone marrow cells was found in group EXP B. Both newly developed biomaterials seem to be suitable as replacements for large bone defects, having good workability and applicability. However, compared to the control group treated with a cancellous autograft, the newly formed bone did not reach the same number of cells settling in and in some cases, full radiological healing was not reached. Nevertheless, the material was found to be grown into the original bone in all cases within the experimental groups. The new biomaterials have a great potential as a substitute in the treatment of large bone defects.

Diplodon granosus (Bruguière, 1792) foi uma das primeiras espécies de bivalves de água doce descritas para a América do Sul. Recentemente, a distribuição de D. granosus foi restrita às bacias dos rios Amazonas e Orinoco, e aos rios costeiros entre essas duas bacias. O presente estudo tem por objetivo registrar uma nova ocorrência de D. granosus em uma praia do rio Tocantins, localizada no município de Mocajuba, estado do Pará, Amazônia Oriental. Com o presente registro, consolida-se a distribuição do bivalve D. granosus no rio Tocantins. Ressalta-se a necessidade de estudos voltados a dinâmica populacional da espécie utilizando uma metodologia que não afete seus indivíduos negativamente, visto que se trata de um Hyriidae com distribuição fragmentada e densidade baixa.

ABSTRACT

 

This study aims to find out the effect of mung bean sprout concentration on the physical and chemical properties of taro flour. The method used in this research was experimental method and was designed using Completely Randomized Design with a single factor experiment (the concentration of mung bean sprouts). There were 5 treatments (0%, 10%, 20%, 30% and 40% of mung bean sprouts), and each treatment were made into 4 replications. Data from the observations were analyzed using analysis of Variance (ANOVA) at 5% significant level using Co-Stat software. If there was significant difference, the data were further tested using the Honest Real Difference test at 5% significant level too. The results showed that the addition of mung bean sprout extract significantly affected the moisture content, protein content, ash content and oxalate content of taro flour. The treatment of 40% mung bean sprout extract is recommended as the best treatment for moisture content (10.53%), ash content (5.24%), protein content (3.84%), calcium oxalate content (0.0268%), water absorption (87.42%), and L value (88.14) of modified taro flour.
