Authors: Yorulmaz Murat , Taş Ayşe
Published: June 2022

Liner shipping, which offers the door-to-door transportation service, has pre-determined departure, arrival and transfer ports and carries cargo mainly through container ships, has been playing a key role in the global cargo transportation industry for more than 60 years and is still growing rapidly. Therefore, understanding of the relationship between service quality, customer satisfaction and behavioral intentions in liner shipping is of critical importance for global competition. From this standpoint, this study aims to determine whether customer satisfaction creates an alternative effect through its mediating effect on the causal relationship between core service quality and customers’ behavioral intentions in liner shipping sector. To do so, it obtains data through survey from forwarder companies that operate in Turkey and analyzes the obtained data using SPSS v22 and AMOS v22 statistical package software. This study concludes that core service quality has a positive effect on customer satisfaction and behavioral intentions, and that customer satisfaction has a mediating effect on the relationship between core service quality and behavioral intentions. It reveals that core service quality and customer satisfaction are important constructs for future behavioral intentions. In conclusion, this study suggests that business managers in liner shipping sector need to incorporate core services that will positively affect customer satisfaction in their marketing policies, and to engage in managerial activities that enhance customer satisfaction.
The influence of SCR on main engine parameters
Authors: Rumac Filip , Glujić Darko , Bernečić Dean
Published: June 2022

Air pollution from ships is increasing due to higher global demand of goods, and with them, global emission standards as well. These standards are prescribed by MARPOL Annex VI and the introduction of emission control areas (ECA). Ships built before 1990. do not have to comply with these rules, but ships built after the early 2000. must follow “NOx Emission Tier I”, which allows 17g/kWh NOx (for the slow speed diesel engines with <130 rpm), and selective catalytic reactors (SCR) are not necessary. Tier III NOx Emission standard was enforced in 2016 and it requires an 80% reduction in NOx emission compared to the Tier I, specifically 3.4 g/kWh, which can not be achieved without SCR or without using some other types of fuels. The focus of this paper is to do analysis how the ammonia dosage to SCR affects to the NOx formation in exhaust gasses on various engine speed (loads), as well as how it affects to some important engine parameters and specific fuel oil consumption (SFOC). The analysis was performed on Kongsberg engine room simulator (ERS), MC 90-V Model, as well as on MATLAB by using mathematical models. All external influences are excluded from the analysis like wind or rough sea. All data on different scenarios has been recorded after prolonged period to avoid inconsistencies. The results are shown graphically, and conclusions are presented.

AbstractThe Department of Student Association (HMJ) is a forum for students to support student learning activities outside of class hours through activities such as extracurricular and co-curricular activities in accordance with their majors. But on the other hand, there is a lot of stigma from some students who say that organizing such as participating in HMJ can hinder the lecture process in the Islamic Broadcasting Communication department. The method used is descriptive qualitative, which is to find out related to a phenomenon according to the experience of the research subject to produce data in the form of a description that contains oral and written speech obtained from the words and behavior of the informant after observation. The results obtained, among others, are the reasons why students participate in HMJ are mostly the same, namely to add experience, relationships, and insight. In addition, to hone their skills and talents. The positive impact of attending HMJ, getting additional material that may not be in the lecture, is more practice. HMJ's role in improving the skills and talent development of KPI students, for example, is conducting writing training, graphic design, public speaking training, editing, cameramanship and other training that is still in line with the KPI department.
Do Immigrants Move to Welfare? Subnational Evidence from Switzerland
Authors: Ferwerda Jeremy , Marbach Moritz , Hangartner Dominik
Published: June 2022

The welfare magnet hypothesis holds that immigrants are likely to relocate to regions with generous welfare benefits. Although this assumption has motivated extensive reforms to immigration policy and social programs, the empirical evidence remains contested. In this study, we assess detailed administrative records from Switzerland covering the full population of social assistance recipients between 2005 and 2015. By leveraging local variation in cash transfers and exogenous shocks to benefit levels, we identify how benefits shape within-country residential decisions. We find limited evidence that immigrants systematically move to localities with higher benefits. The lack of significant welfare migration within a context characterized by high variance in benefits and low barriers to movement suggests that the prevalence of this phenomenon may be overstated. These findings have important implications in the European setting, where subnational governments often possess discretion over welfare and parties frequently mobilize voters around the issue of “benefit tourism.”

Published: June 2022

When we enter college, we will be introduced to various kinds of Student Activity Units (UKM) usually, early semester students are encouraged to join the UKM they are interested in. This UKM can be followed by all students, usually, students take part in UKM activities from semester 1 to semester 7. The purpose of this research is to analyze the opportunities and challenges of UKM in improving student achievement. The results of this study indicate that the impact of good and bad times depends on us responding to them. Functional strata in UKM is very influential on student achievement, for example, seen in their knowledge, most people who participate in UKM tend to have a lot of peer and senior relations and easily mingle with anyone outside UKM, making it easier for them to explore knowledge, either through lecturers, seniors and peers. Meanwhile, people who do not participate in UKM tend to feel more embarrassed and find it difficult to blend in and adapt to the surrounding environment. Structural functional on student achievement has a big influence if we occupy the according to our passion. Usually in an organization, we can improve our communication skills because we will get used to speaking in public and carrying out work programs in it. Each UKM has its own bittersweet, so if we are tired, rest, not give up.

Interpersonal communication is the most basic thing. Thanks to good interpersonal communication, making the relationship that exists will be good. In the k-drama “Hometown cha-cha-cha”, there are several scenes that depict interpersonal communication between players. Hometown Cha-Cha-Cha itself is a TV series adapted from the 2004 film "Mr. Hong". Although they still use the same character names, the plot of Hometown Cha-Cha-Cha is different from the original film. The drama, directed by Yoo Je-won, will be released in August 2021. The purpose of this study is to understand the interpersonal communication patterns in the k-drama “Hometown cha-cha-cha” and explore the importance of empathizing with others. This type of research is a descriptive qualitative and semiotic data analysis model by Roland Barthes. From the results of the study, it was found that the communication between the "Hometown Cha-Cha-Cha" players was dyadic communication (communication between two people) which was carried out both primary and secondary. However, we can also find forms of triadic communication (communication of three people).

The role of attention in decision-making under risk in gambling disorder: an eye-tracking study
Authors: Hoven Monja , Hirmas Alejandro , Engelmann Jan Benjamin , van Holst Ruth
Published: June 2022

Gambling disorder (GD) is a behavioural addiction characterized by impairments in decision-making, favouring risk- and reward-prone choices. One explanatory factor for this behaviour is a deviation in attentional processes, as increasing evidence indicates that GD patients show an attentional bias toward gambling stimuli. However, previous attentional studies have not directly investigated attention during risky decision-making. 25 patients with GD and 27 healthy matched controls (HC) completed a mixed gambles task combined with eye-tracking to investigate attentional biases for potential gains versus losses during decision-making under risk. Results indicate that compared to HC, GD patients gambled more and were less loss averse. GD patients did not show a direct attentional bias towards gains (or relative to losses). Using a recent (neuro)economics model that considers average attention and trial-wise deviations in average attention, we conducted fine-grained exploratory analyses of the attentional data. Results indicate that the average attention in GD patients moderated the effect of gain value on gambling choices, whereas this was not the case for HC. GD patients with high average attention for gains started gambling at less high gain values. A similar trend-level effect was found for losses, where GD patients with high average attention for losses stopped gambling with lower loss values. This study gives more insight into how attentional processes in GD play a role in gambling behaviour, which could have implications for the development of future treatments focusing on attentional training or for the development of interventions that increase the salience of losses.
A Theology of Human Flourishing for Positive Psychology Pedagogy
Authors: Kapic Kelly M , Hall M. Elizabeth Lewis , McMartin Jason
Published: June 2022

Research interest in human flourishing continues to grow across multiple disciplines. In this article, we suggest means by which Christian theology can inform teaching positive psychology. We survey the field of positive psychology by characterizing and distinguishing theories regarding eudaimonic and hedonic accounts of flourishing. Christian theological approaches diverge from the emphases of psychology by grounding flourishing outside of the self. Love, properly understood, links various Christian proposals regarding the nature of flourishing and circumscribes the relationships in need of flourishing: with God, with each other, with ourselves, and with the rest of creation. From this follow several pedagogical implications: 1) grounding positive psychology in love, 2) linking love of God to psychology of religion and spirituality, 3) using love to unify the study of traits, 4) including emic versions of positive traits, 5) incorporating discussion of positive institutions, 6) tempering positive psychology with a theology of suffering, and 7) using cross-cultural perspectives.
Will-Powered: Synchronic Regulation is the Difference-Maker for Self-Control
Authors: Irving Zachary , Bridges Jordan , Glasser Aaron , Bermúdez Juan Pablo , Sripada Chandra
Published: June 2022

Philosophers, psychologists, and economists have reached the consensus that one can use two different kinds of regulation to achieve self-control. Synchronic regulation uses willpower to resist current temptation. Diachronic regulation implements a plan to avoid future temptation. Yet this consensus may rest on contaminated intuitions. Specifically, agents typically use willpower (synchronic regulation) to achieve their plans to avoid temptation (diachronic regulation). So even if cases of diachronic regulation seem to involve self-control, this may be because they are contaminated by synchronic regulation. We therefore developed a novel multifactorial method to disentangle synchronic and diachronic regulation. Using this method, we find that ordinary usage assumes that only synchronic––not diachronic––regulation counts as self-control. We find this pattern across four experiments involving different kinds of temptation, as well as a paradigmatic case of diachronic regulation based on the classic story of Odysseus and the Sirens. Our final experiment finds that self-control in a diachronic case depends on whether the agent uses synchronic regulation at two moments: when she (1) initiates and (2) follows-through on a plan to resist temptation. Taken together, our results strongly suggest that synchronic regulation is the sole difference maker in the folk concept of self-control.

Published: June 2022

I boken Professional Capital – Transforming Teaching in Every School sier Hargraves og Fullan: “Sustainable improvement can […] never be done to or even for teachers. It can only ever be achieved by and with them (2012:45). Dette sitatet fra Hargraves og Fullan angir forskningsinnretningen i dette utviklingsprosjektet. Formålet er å studere hvordan lærere involveres, engasjeres og lærer i innovasjoner i Jærskulen. Forskningsinteressen er sentrert om utviklingsaktiviteter som er satt i verk og hvordan disse relateres til lærernes profesjonsutvikling. Basert på innspill fra utviklingsleder i Jærskulen, Mats Bryne, er prosjektet konsentrert om fire innovasjoner i jærskolesamarbeidet: - Lokal skoleutvikling med utgangspunkt i skolenes valgte utviklingsområder - Gjennomføring i videregående opplæring - Profesjonsutvikling i samspill, medskaping i samarbeid med Utdanningsforbundet - Læringsteknologi i undervisningen Felles for de fire delprosjektene er at de rapporterer om engasjerte lærere som deltar i ulike innovasjonsprosesser, lokalt på de enkelte skolene og i nettverkssamarbeid mellom skoler. I så måte synes målsettingen om at «Jærskulen har eit godt læringsmiljø med god kultur for læring» – også å gjelde for lærerne. Samtidig peker delprosjektene på utfordringer og konstruktive veier for videreutvikling av innovasjonene. Studien av lokal skoleutvikling presenteres i kapittel 1. Denne er utført av Anne Nevøy og Lars Helle og har fått tittelen «Skolenes utviklingsplaner og lærerprofesjonen». Christina Finne og Stein Erik Ohna står bak studien av «Gjennomføring i videregående skole», og denne presenteres i kapittel 2. Utforskingen av «Profesjonsutvikling i samspill» - har fått undertittelen «Utdanningsforbundet og Jærskulen ‘At det er en prosess i det hele’. Nina Helgevold og Kåre Andreas Folkvord har gjennomført studien og denne presenteres i kapittel 3. Kapittel 4 handler om læringsteknologi i undervisningen. Denne studien er utført av Jorunn Thortveit og Hans Erik Bugge, og har fått tittelen «Ipad i Jærskulen».
Application of Metal/Metal Oxide Doped Electrospun Nanofiber Membranes in Sustainable Catalysis

Published: June 2022

The unsustainability of the production of catalysts due to limited resources and higher energy demands makes it critical to explore and reengineer new catalytic materials for future applications. Woefully, the unrelenting demand for the metals/metal oxides increases both the financial and environmental cost, particularly in mining and synthesis, rendering consumption unsustainable in its current form. In this context, electrospinning offers a new template for designing sustainable ways of minimizing the higher loading of catalysts and recyclability. In this context, metals/metal oxide doped electrospun membranes have grasped a great scientific interest as sustainable catalysts due to their enhanced catalytic activity and synergistic structure-property relationship of the doped material and the matrix. More specifically, the selectivity arising from the electronic properties and quantum mechanical interactions at the nanoscale of metal/metal oxide nanoparticles coupled with interactions at the electrospun membrane interfaces lead to such enhanced properties. This review article summarizes the applications of metals/metal doped electrospun membranes in different aspects of catalysis, such as thermocatalysis, photocatalysis, organocatalysis and electrocatalysis, with a particular focus on their sustainability.

Keywords: Sustainable catalysis, metal/metal oxide doped catalysts, electrospinning, organocatalysis, photocatalysis

The Electro-Fenton oxidation process was carried out at an ambient temperature at different current density (2, 4, 6, 8 mA/cm2) for up to 6 h. Sodium Sulfate at a concentration of 0.05M was used as a supporting electrolyte, and 0.4 mM of Ferrous ion concentration (Fe2+) was used as a catalyst. The electrolyte cell consists of graphite modified by an electrodepositing layer of PbO2 on its surface as anode and carbon fiber modified with Graphene as a cathode. The results indicated that Phenol concentration decreases with an increase in current density, and the minimum Phenol concentration obtained after 6 h of electrolysis at 8 mA/cm2 is equal to 7.82 ppm starting from an initial concentration about 155 ppm. The results obtained from the kinetic study of Phenol oxidation at different current density showed that the reaction followed pseudo first-order kinetics regarding current density. Energetic parameters like specific power consumption and current efficiency were also estimated at different current density. The results showed that an increase in current density caused an increase in the specific power consumption of the process and decreased current efficiency.

The effective interaction between humans and robotic devices is designed to provide a timely response to potentially dangerous situations arising in complex environments. One example is the use of Unmanned Aerial Vehicles (UAVs) by human operators to inspect enclosed spaces. These units allow the search and identification of target objects, helping a human operator identify signs of Potentially Dangerous Situations (PDSs). At the same time in a closed (and often cluttered) space to control the emerging situations it is necessary to involve developed means of conducting spatial orientation based on Artificial Intelligence Technology, Computer Vision, 3D-visualization, Local Positioning And Navigation, etc. Despite the progress made in autonomous UAVs control, active human participation in detecting signs of PDSs is an important condition for maintaining the security of the internal environment of controlled premises. Human decision-making in situations of high uncertainty and incomplete data largely depends on means to improve his Situational Awareness (external conditions of activity) and Professional Competencies (internal conditions of activity). To form them, it is necessary to develop methodology and tools for building UAVs application scenarios to give operators the necessary user experience on simulation models in the Virtual Environment of Activity. The paper investigated the development of the Virtual Environment Systems (VES) for the implementation of UAVs application scenarios in enclosed spaces in relation to multicopters that allow both autonomous and manual control. As a result of this research, prototypes of UAVs for inspection of enclosed spaces have been identified; the prospects of quadcopters use under various PDSs scenarios have been shown; the composition of promising technologies ensuring UAVs use in enclosed environments has been described; the method of design and 3D visualization of UAVs application scenarios using the original VES (named VirSim) has been proposed. The advantages of the proposed approach to modeling the use of UAVs in PDSs are the multivariate scenarios of operators' activities, which contributes to the accumulation of user experience of human interaction with flying robots.

The self-driving unmanned ground vehicles (UGV) design problem is analyzed in this paper. Two methodological problems of UGV design are formulated. The first problem is the difference between the purpose of creating a self-driving automobile from UGV, which leads to fundamentally different systemic solutions. The second methodological problem is associated with the need for sufficiently deep knowledge and the ability to work with a number of technologies that are used in the complex to create a control system for self-driving. The joint analysis of these problems allowed us to put forward a number of control systems design principles for self-driving UGV, including the principle of upcycling, the principle of using a discrete-event model for the logical synchronization of the operation of modules and the principle of ensuring the functional safety of the UGV during autonomous movement. The principle of using the discrete-event model for synchronizing the operation of software modules is explained by the example of a Petri net. A general solution to the problem of quantitative evaluation of the safety of autonomous movement of UGV is presented. The considered principles were used during development of prototypes of self-driving control systems for various purposes.

The individual and mutual effects of the key parameters for hydrogen production in a photo-bioreactor containing Halobacterium salinarium MTCC 1626 immobilized in calcium alginate and E. coli MTCC 40 were investigated through factorial and the Box-Behnken experimental design. A full factorial design was utilized to determine the optimal ratio of H. salinarium and E. coli for maximum hydrogen production. The Box-Behnken design was used to optimize temperature, pH, light intensity, and stirrer speed in a photo-bioreactor. The quadratic model adequately predicted the individual and interaction effects of the variables. The optimal rate of hydrogen production of 53.22 mL/L.h was obtained with 50% E. coli and 15% immobilized H. salinarium with calcium alginate. The maximum experimental rate of hydrogen production of 75.8 mL/L.h was obtained at an initial pH of 7.38, a temperature of 35.8 oC, a light intensity of 12186 lux, and a stirring speed of 104 rpm.

Reducing hazardous chemicals in chromatography and improving the fast, safe sample preparation process is the goal of an environmentally friendly and green approach. A fast and specific UPLC-MS/MS technique has been developed and validated to simultaneously determine metformin (MET) and glimepiride (GLM) in human plasma. Glipizide was used as an internal standard (IS), and analytes were extracted using the protein precipitation method with acetonitrile containing 0.1% formic acid. Chromatographic separations were performed on the BEH C18 column (1.7 µm, 2.1 mm x 50 mm) and pre-column. Elution was carried out through a gradient program using water and acetonitrile; both added 0.1% formic acid. Tandem mass spectrometry and positive ion-electrospray ionization, and the multiple reaction monitoring modes were used to detect fragment ions of the active ingredients. Precursor ion to fragment ion transitions included 130.0 → 70.9 m/z, 491.3 → 352.1 m/z, and 446.2 → 99.9 m/z for MET, GLM, and IS, respectively. The method was improved and verified in accordance with US Food and Drug Administration guidelines. Linear curves range from 1-100 ng/mL for MET and 0.25-25 ng/mL for GLM. The approach has quantitative limits of 1 ng/mL for MET and 0.25 ng/mL for GLM. The obtained recoveries were higher than 85%, while the coefficient of variation (%CV) was below 15% for all analytes. This study has provided an environmentally friendly solution, and improved sensitivity, and analysis time so it can be used to monitor drug concentration in plasma.

The goal of the research was to find out the concentration of phenolic and flavonoid content and also to identify the hemostatic activity of the ethanolic extract of beetroot (Beta vulgaris L) in heparin-induced thrombocytopenia rats. The identification of total phenol content using Folin-Ciocalteu as reagent and flavonoid content were determined by spectrophotometer and continued to the determination of hemostatic activity using heparin as an inducer and then determined the bleeding time, platelet count, and prothrombin time. The results showed that the ethanol extract of beetroot had a total phenolic content of 312.2 mg GAE/g extract and a flavonoid content equivalent to 38.5 mg quercetin equivalent/g. The investigation of bleeding time at doses of 100 mg/kg BW, 200 mg/kg BW, and 400 mg/kg BW was significantly different (p<0.05P) compared to the negative group. The dose of 400 mg/kg BW reduced the bleeding time by 5.90±0.11 minutes, which was substantially different from the other doses (p<0.05). At a dose of 400mg/kg BW, the greatest platelet count number was seen, which was statistically different from the control group (p<0.05) The prothrombin Time (PT) values at a dose of 400 mg/kg BW likewise revealed increased activity and were significantly different (p>0.05) from the negative group. The ethanol extract of beetroot (Beta vulgaris L) possesses hemostatic action and is dose-dependent, with a total phenolic concentration of 312.2 mg GAE/g extract and a flavonoid content equivalent to 38.5 mg quercetin equivalent/g extract.
