Influence of Cognitive Engagement on Temptation and Decision Making
Authors: Hull Bailey Ryen 
Published: February 2019

The purpose of this study is to determine students’ heightened susceptibility to temptation when cognitively engaged. Cognitively straining tasks require considerable focus, which inhibits the brain from the ability to effectively multi-task (Molfese et al., 2006). This may reduce the capacity for executive control during such engagement. This hypothesis was evaluated by offering participants an unhealthy (chocolate) or healthy (celery) food option during a memorization task (experimental group) or following a memorization task (control group). In the experimental group, students are cognitively engaged at the moment of the choice. This allows for the study to compare decision-making between the experimental and control group. Participants required to make a decision while actively participating in the memorization task chose the chocolate option significantly more often than participants who were offered the food after they had disengaged from the cognitive strain. This study could provide insight into how susceptible to temptation students are while under mental strain. It was hypothesized that as students are participating in a cognitively engaging task similar to studying, they will be more susceptible to choosing an unhealthy sugary snack rather than a healthier option. The data supported the idea that students who are cognitively engaged will be more susceptible to this temptation.
Non-Stationarity in Stochastic Distributions of Cryptocurrency Returns
Authors: Wu Adam 
Published: February 2019

This paper uses a functional approach to analyze the distributions of weekly returns in Bitcoins on leading cryptocurrency exchanges. The results present strong evidence for non-stationarity, which suggests unpredictability and time-varying statistical properties. In addition, non-stationary fluctuations tend to be primarily concentrated in even moments, such as volatility and kurtosis—however their effect is significant and persistent in every moment, including higher moments. The analysis in this paper proposes that the Bitcoin market is maturing and tending towards stability, but retains a high degree of unpredictability in the case of random shocks due to underlying market dynamics.
Cross-Functional Training of Front-Line Hotel Employees, In-Role and Extra-Role Job Performance, Customer Satisfaction, and Customer Loyalty: A conceptual Model Proposal
Authors: SUMANEEVA Ksenia A. , ELUWOLE Kayode Kolawole , AVCI Turgay 
Published: February 2019

The purpose of this paper is to develop the theoretical conceptual model regarding benefits of cross-functional training of frontline hotel employees from interrelated departments of hospitality organizations for further investigation. This study aims to review the hospitality management literature and provide the conceptual model of cross-functional training and its connection to customer loyalty via the mediating role of individual job performance (e.g., in-role and extra-role employees’ job performance) and customer satisfaction in the hotel context.
This paper identifies the gap within existing studies regarding consequences of frontline hotel employees’ cross-functional training and proposes the new conceptual model for the further investigation through extensive literature review of relevant literature.
Hotel managers implement training programs to develop frontline hotel employees’ skills, motivate them to perform better and provide high-quality service to the customers. This paper proposes that cross-functional training of frontline hotel employees can be used to build strong coordination and integration between frontline hotel employees from interrelated hotel departments (e.g., front office, housekeeping, room service, F and B), increase employees’ awareness regarding other departments’ procedures, what, in turn, may significantly improve their individual job performance (e.g., in-role and extra-role performance), increase customer satisfaction and customers loyalty.
This study attempts to fill the existing gaps in the literature regarding the benefits of cross-functional training by suggesting the new conceptual model regarding frontline hotel employees’ cross-functional training, and its link to frontline hotel employees’ in-role and extra-role job performance, customer satisfaction, and customer loyalty for the further investigation. This proposed conceptual model integrates contribution of three main parties of the hotel organization (e.g., supervisors, frontline hotel employees, and customers) as the proposed variables should be investigated by collecting data from different sources.

ABCB4/MDR3 in health and disease – at the crossroads of biochemistry and medicine
Authors: Prescher Martin , Kroll Tim , Schmitt Lutz 
Published: February 2019

Abstract
Several ABC transporters of the human liver are responsible for the secretion of bile salts, lipids and cholesterol. Their interplay protects the biliary tree from the harsh detergent activity of bile salts. Among these transporters, ABCB4 is essential for the translocation of phosphatidylcholine (PC) lipids from the inner to the outer leaflet of the canalicular membrane of hepatocytes. ABCB4 deficiency can result in altered PC to bile salt ratios, which led to intrahepatic cholestasis of pregnancy, low phospholipid associated cholelithiasis, drug induced liver injury or even progressive familial intrahepatic cholestasis type 3. Although PC lipids only account for 30–40% of the lipids in the canalicular membrane, 95% of all phospholipids in bile are PC lipids. We discuss this discrepancy in the light of PC synthesis and bile salts favoring certain lipids. Nevertheless, the in vivo extraction of PC lipids from the outer leaflet of the canalicular membrane by bile salts should be considered as a separate step in bile formation. Therefore, methods to characterize disease causing ABCB4 mutations should be considered carefully, but such an analysis represents a crucial point in understanding the currently unknown transport mechanism of this ABC transporter.
Molecular effects of dietary fatty acids on brain insulin action and mitochondrial function
Authors: Chudoba Chantal , Wardelmann Kristina , Kleinridders André 
Published: February 2019

Abstract
The prevalence of obesity and its co-morbidities such as insulin resistance and type 2 diabetes are tightly linked to increased ingestion of palatable fat enriched food. Thus, it seems intuitive that the brain senses elevated amounts of fatty acids (FAs) and affects adaptive metabolic response, which is connected to mitochondrial function and insulin signaling. This review will address the effect of dietary FAs on brain insulin and mitochondrial function with a special emphasis on the impact of different FAs on brain function and metabolism.
Video Steganography Using Knight Tour Algorithm and LSB Method for Encrypted Data
Authors: Younus Zeyad Safaa , Younus Ghada Thanoon 
Published: February 2019

Abstract
This paper aims to propose a method for data hiding in video by utilizing the least significant bit (LSB) method and improving it by utilizing the knight tour algorithm for concealing the data inside the AVI video file and using a key function encryption method for encrypting the secret message. First, the secret message is encrypted by utilizing a mathematical equation. The key used in the equation is a set of random numbers. These numbers differ in each implementation to warrant the safety of the hidden message and to increase the security of the secret message. Then, the cover video was converted from a set of frames into separated images to take the advantage of the large size of video file. Afterward, the knight tour algorithm is utilized for random selecting of the pixels inside the frame utilized for embedding the secret message inside it to overcome the shortcoming of the conventional LSB method that utilized the serial selection of pixel and to increase the robustness and security of the proposed method. Afterward, the encrypted secret message is embedded inside the selected pixels by utilizing the LSB method in bits (7 and 8). The observational results have drawn that the proposed method has a superior performance compared to the previous steganography method in terms of quality by a high PSNR of 67.3638 dB and the lowest MSE of 0.2578. Furthermore, this method preserves the security where the secret message cannot be drawn out without knowing the decoding rules.

Published: February 2019

Abstract
Being an important class of water-soluble synthetic polymers, polyacrylamide (PAM) and its derivatives have found a wide range of applications in the oil and gas industry. Due to the increasingly active exploration of deep and ultra-deep wells, PAM-based polymers are more and more frequently applied under hostile subterranean conditions, particularly high temperature. Therefore, it becomes an imminent research topic to elucidate the thermal degradation pathways of PAM-based polymers in order to upgrade these chemicals for more challenging scenarios. Neighboring groups attached to the same polyvinyl backbone have been suggested to exert an effect to the degradation of the PAM-based polymers. Herein we report a combined theoretical and experimental study on the energetics of such neighboring group effect. Taking advantage of a computational method based on density functional theory, we have identified two competing degradation pathways in neutral medium and have calculated their respective activation energies. These results enable us to predict the relative thermal stabilities of a series of PAM-based polymers, and we have also used temperature-variant rheology measurements to verify these predictions. This work will guide the design of better heat-resistant PAM-based products.
Drosophilaas a Genetic Model for Hematopoiesis
Authors: Banerjee Utpal , Girard Juliet R , Goins Lauren M , Spratford Carrie M 
Published: February 2019

AbstractIn this FlyBook chapter, we present a survey of the current literature on the development of the hematopoietic system in Drosophila. The Drosophila blood system consists entirely of cells that function in innate immunity, tissue integrity, wound healing, and various forms of stress response, and are therefore functionally similar to myeloid cells in mammals. The primary cell types are specialized for phagocytic, melanization, and encapsulation functions. As in mammalian systems, multiple sites of hematopoiesis are evident in Drosophila and the mechanisms involved in this process employ many of the same molecular strategies that exemplify blood development in humans. Drosophila blood progenitors respond to internal and external stress by coopting developmental pathways that involve both local and systemic signals. An important goal of these Drosophila studies is to develop the tools and mechanisms critical to further our understanding of human hematopoiesis during homeostasis and dysfunction.
Modulation of Gene Silencing by Cdc7p via H4 K16 Acetylation and Phosphorylation of Chromatin Assembly Factor CAF-1 in Saccharomyces cerevisiae
Authors: Young Tiffany J , Cui Yi , Irudayaraj Joseph , Kirchmaier Ann L 
Published: February 2019

Abstract
CAF-1 is an evolutionarily conserved H3/H4 histone chaperone that plays a key role in replication-coupled chromatin assembly and is targeted to the replication fork via interactions with PCNA, which, if disrupted, leads to epigenetic defects. In Saccharomyces cerevisiae, when the silent mating-type locus HMR contains point mutations within the E silencer, Sir protein association and silencing is lost. However, mutation of CDC7, encoding an S-phase-specific kinase, or subunits of the H4 K16-specific acetyltransferase complex SAS-I, restore silencing to this crippled HMR, HMRae**. Here, we observed that loss of Cac1p, the largest subunit of CAF-1, also restores silencing at HMRae**, and silencing in both cac1Δ and cdc7 mutants is suppressed by overexpression of SAS2. We demonstrate Cdc7p and Cac1p interact in vivo in S phase, but not in G1, consistent with observed cell cycle-dependent phosphorylation of Cac1p, and hypoacetylation of chromatin at H4 K16 in both cdc7 and cac1Δ mutants. Moreover, silencing at HMRae** is restored in cells expressing cac1p mutants lacking Cdc7p phosphorylation sites. We also discovered that cac1Δ and cdc7-90 synthetically interact negatively in the presence of DNA damage, but that Cdc7p phosphorylation sites on Cac1p are not required for responses to DNA damage. Combined, our results support a model in which Cdc7p regulates replication-coupled histone modification via a CAC1-dependent mechanism involving H4 K16ac deposition, and thereby silencing, while CAF-1-dependent replication- and repair-coupled chromatin assembly per se are functional in the absence of phosphorylation of Cdc7p consensus sites on CAF-1.

Abstract: The mortality of severe ARDS is almost 60%. Ventilation-associated lung-injury can be avoided by low-pressure, low-volume ventilation. Potential use of ECMO in case of refractory hypoxemia beside modern ventilatory therapy can be considered. Increasing numbers of respiratory ECMO runs are seen worldwide, though the efficacy remains controversial. The authors present the first successful venovenous-ECMO treatment in severe ARDS in our Institute. We report the case of a 67-year-old male who was admitted with community-acquired pneumonia caused by Legionella. Despite empirical and later targeted antibiotic therapy, severe ARDS with sepsis evolved. Neither ventilation nor prone position resulted in permanent improvement in oxygenation. The patient was referred to our Institute for extracorporeal life support (ECLS) therapy. On admission, blood gas showed severe hypoxemia with mild hypercapnia (PaO2/FiO2: 60, pCO2: 53 mmHg at PEEP: 14 mmHg, PIP: 45 mmHg). X-ray showed bilateral patchy infiltrates while cardiac impairment (EF: 45%) and dilated right ventricle were seen on echocardiography. Elevated pulmonary artery pressure (mPAP: 41 mmHg) was measured. After implantation of femoral-jugular VV ECMO, oxygen saturation was appropriate with lung protective ventilation (FiO2: 0.5, TV: 3–4 ml/kg). Improving lung function enabled us to stop ECMO after 8 days and further 5 days later the patient was weaned off ventilation. After 21 days of intensive care we discharged him to the referral hospital. By reporting this case we emphasise the potential role of respiratory ECMO. Consideration should be given to increase the contingent of this modality in the Hungarian intensive care in accordance with international practice. Orv Hetil. 2019; 160(6): 235–240.

Corruption, financial disequilibrium, unemployment, inflation, among other factors, have been the cause of the general crisis in today’s society, they have produced a time lag for the economic, educational and social development of Latin American countries. Colombia is not the exception to this set of problems, on the contrary, it is a country that today has been hit by economic and financial difficulties, corruptive acts at a national governmental level, drug trafficking, and a series of conflicts that have brought instability to the productive system of the country, therefore affecting growth in as much as competitiveness, innovation and technology.
Facing these problems from the national government point of view, it is necessary to shape some educative policies at a higher educational level. The Higher Educational Institutions, including technical and technological must make reforms to their institutional structures, adapting them to market demands. That is why, inside general parameters, the education of teachers must be included as a main cross sectional axis for student’s learning.
