Strategic Management Technical Skills, Interpersonal Skills and Conceptual Skills of Officers in Manning KRI
Authors: Sutanto Rudy
Published: August 2021

To achieve increased professionalism, the officers were disturbed by several shipwrecks that occurred. During the period 2013-2016, there have been 32 KRI accidents, the data can show an increasing trend of KRI accidents. In the maritime world, several ship accidents occur due to, among others, natural conditions, technical failures, shipping lane conditions, ship-related factors, human error, and cargo-related factors. This research uses a qualitative research approach with a case study method. From the research results, the ship which weighs 1,900 tons, has dimensions of 90.70 meters x 11.12 meters x 3.4 meters, is powered by 2 diesel engines, which can propel the ship up to a speed of 18 knots and can carry cargo up to 600 tons. happened when the ship finished docking. The habit factor of the ships above, anchoring like that, of course, has a reason, the Commander should in the learning process find out to enrich knowledge through experience to find the truth of the habit because one day it becomes one of the keys to work effectiveness and benefits in taking an action. If he learns from experience, leakage can be avoided. The results of the research show that expertise and responsibility are two of the pillars of professionalism, which are relevant to the case study of the shipwreck that the researcher lifted. The results of the ship accident case study, identified that to prevent accidents, officers must have technical, interpersonal, and conceptual skills. These three factors constitute a totality. This means that all three are interrelated and all KRI officers need some mix of all three. If one of them is not perfect or does not exist, it will have implications for shipping safety.
Why the aortic dissection detection risk score is problematic in emergency departments
Authors: Kelly Anne-Maree
Published: August 2021

Acute aortic syndromes, including aortic dissection (AD), are rare. The AD detection risk score (ADDRS) and associated investigation pathway were developed to reduce missed diagnosis of AD. The methodology for its development was sub-optimal and it has not been robustly validated in the emergency department chest pain population. Recent research suggests that it will drive over-investigation and that the risks of missed diagnosis may not be in balance with the risks of the testing strategy. There are serious doubts about whether the score and investigation pathway are fit for purpose.

Einfluss der Lastverteilung auf die dynamische Tragwerksantwort von Eisenbahnbrücken bei Hochgeschwindigkeitsverkehr/Influence of load distribution on the dynamic response of railway bridges under high-speed traffic
Authors: Bettinelli Lara , Stollwitzer Andreas , Fink Josef
Published: August 2021

Im Eurocode 1 wird für den Nachweis von Eisenbahnbrücken zufolge dynamischer Beanspruchung insbesondere für Tragwerke mit kurzen Spannweiten die Berücksichtigung der Lastverteilung durch den Schotter-

 

oberbau empfohlen. Um dessen Einfluss auf die dynamische Tragwerksantwort von Einfeldträgerbrücken unterschiedlicher Spannweite und Eigenfrequenz zu evaluieren, werden in diesem Beitrag Berechnungen an sechs Beispieltragwerken ausgewertet. Dabei werden zwei Fahrzeugmodelle angewendet: das Modell der bewegten Einzellasten und ein komplexeres Mehrkörpermodell, welches die Fahrzeug-Brücken-Interaktion berücksichtigt. Die lastverteilende Wirkung des elastisch gebetteten Gleises wird bei beiden Fahrzeugmodellen vereinfachend auf Einwirkungsseite durch die Aufteilung der vom Zug auf das Tragwerk übertragenen Radkontaktkräfte auf drei oder fünf Schienenstützpunkte abgebildet. Die Ergebnisse deuten darauf hin, dass sich die Lastverteilung auf Berechnungen mit und ohne Berücksichtigung der Fahrzeug-Brücken-Interaktion vergleichbar auf die Reduktion der Beschleunigungen auswirkt. Des Weiteren wird gezeigt, für welche Tragwerkseigenschaften und Überfahrtsgeschwindigkeiten der Nutzen der Berücksichtigung der Lastverteilung besonders ausgeprägt ist.
Boden-Bauwerk-Interaktion unter Berücksichtigung von tiefen- und frequenzabhängigen, viskosen Dämpferelementen an den Halbraumrändern/Depth and frequency dependent dashpots in context of Rayleigh-Wave reflection
Authors: Heiland Till , Stempniewski Lothar
Published: August 2021

Berechnungen der Boden-Bauwerk-Interaktion unter Berücksichtigung des homogenen Halbraumes beinhalten die Problematik der Wellenreflexion, welche die ungestörten Ergebnisse verstimmt und eine Diskrepanz entstehen lässt. Reflexionsfreie Berechnungen können nur in einem unbegrenzten Halbraum durchgeführt werden, der innerhalb der FEM aber nicht existiert. In der Praxis werden häufig tiefen- und frequenzunabhängige (lineare) viskose Dämpferelemente für die Simulation infiniter Randbedingungen verwendet. Dieser Ansatz geht mit nicht zu vernachlässigenden Reflexionen von Oberflächenwellen, wie der Rayleigh-Welle, einher, welche maßgeblich für die Übertragung von Erschütterungen verantwortlich sind.

 

In diesem Beitrag wird das tiefen- und frequenzabhängige Geschwindigkeitsfeld der Rayleigh-Welle bei der Formulierung der viskosen Dämpferelemente berücksichtigt. Es wird gezeigt, dass auf diese Weise für impulsförmige und harmonische Anregungen die Reflexion der Rayleigh-Welle reduziert werden kann. Aufgrund der geringeren Reflexionen an den Modellrändern verbessert sich die Prognose der Erschütterungsausbreitung.
Dynamische Bewertung der Zusammensetzung von Flächenarten auf Baustellen/Dynamic evaluation of the composition of area types on construction sites
Authors: Nitsche Andreas , Zander Niklas , Stonis Malte , Nyhuis Peter
Published: August 2021

Auf innerstädtischen Baustellen steht meist nur ein begrenztes Flächenangebot zur Verfügung. Dadurch steigt die Komplexität in der Durchführung entsprechender Bauprojekte und zugleich das Risiko von Terminverschiebungen. Sowohl die Zusammensetzung des Bedarfs an spezifischen Flächenarten sowie deren Bedarfsentwicklung während der Bauzeit sollten im Zuge der Terminplanung Berücksichtigung finden. Eine Möglichkeit der Bewertung des Flächenbedarfs besteht über die Einführung des Wandlungspotenzials als Indikator für die Eigenschaft einer Fläche, bei möglichen kurzfristigen Änderungen im Bauprojekt flexibel angepasst werden zu können. Damit kann eine Bewertungsgrundlage geschaffen werden, die zunächst eine Entscheidungsunterstützung für Projektplaner darstellt und nachfolgend in optimierende Verfahren zur Terminplanung integriert werden kann. Dadurch kann die Güte eines Terminplans in Zusammenhang mit dessen Robustheit in positiver Sicht beeinflusst werden.

 

Dieser Beitrag beschreibt die Entwicklung einer Methode zur Bewertung von Flächenbedarfen und eine Möglichkeit der Integration in die Terminplanung von Bauprojekten. Es erfolgt eine anschließende Validierung der Methode anhand eines Praxisbeispiels. Abschließend werden die Ergebnisse resümiert.

Treatment-Resistant Depression: Approaches to Treatment
Authors: Kverno Karan S. , Mangano Emma
Published: August 2021

Approximately 30% of people treated for a major depressive episode will not achieve remission after two or more treatment trials of first-line antidepressants and are considered to have treatment-resistant depression (TRD). Because the odds of remission decrease with every subsequent medication trial, it is important for clinicians to understand the characteristics and risk factors for TRD, subtypes of major depressive disorder that are more likely to be less responsive to first-line anti-depressants, and the available treatment options. In the current article, we review the approved treatments for TRD, including esketamine, and the evidence for psilocybin and pramipexole. Although limited in specificity, guidelines to help prescribers identify person-centered treatments for TRD are available. [

The decrease in soil productivity and quality caused by the continuous and abusive use of mineral fertilizers makes necessary to adopt more sustainable agricultural soil management strategies that help to maintain soil edaphic fertility. In light of these considerations, we have evaluated the effect of organic vs. inorganic fertilization on soil microbial communities, soil quality, and crop yield in a melon crop. The following treatments were tested: i) aerobic sewage sludge from a conventional wastewater treatment plant (WWTP) using aerobic bacteria (SS); ii) aerobic sewage sludge from a WWTP using a bacteria-microalgae consortium (B); iii) N-P-K mineral fertilizer (M); iv) a treatment in which 50% of the N was contributed by SS and 50% by mineral fertilizer (M + SS); v) a treatment in which 50% of the N was contributed by B and 50% by mineral fertilizer (M + B); and vi) a no-fertilized control soil. Melon yield and fruit quality were determined in addition to several soil physical, chemical, biochemical and microbiological parameters. Organic fertilizers (SS and B) increased the percentage of soil water-stable aggregates (52 and 60% respectively) as well as the content of organic C (18 and 31%), water soluble C (21 and 41%), N (15 and 41%) and available P content (41 and 82%) compared to inorganic fertilization. They also stimulated bacterial and fungal abundance to a greater extent than mineral fertilizers (189 and 242% vs 85%, and 57 and 122% vs 29%, respectively), as well as soil respiration, and dehydrogenase, β-glucosidase, phosphatase, urease, and glycine aminopectidase activities. The analysis of principal components with parameters linked to soil quality clearly showed that organic fertilizers cause a greater improvement in soil characteristics and microbial community than mineral fertilizers. Results demonstrate that organic and combined fertilization could be used as substitutes for nitrogen mineral fertilizers in melon crop, since these treatments led to similar melon production and quality while improving soil characteristics and microbial population size and activity.
Centricities of STEM curriculum frameworks: Variations of the S-T-E-M Quartet
Authors: Teo Tang Wee , Tan Aik Ling , Ong Yann Shiou , Choy Ban Heng
Published: August 2021

This commentary is an extension to the integrated S-T-E-M Quartet Instructional Framework that has been used to guide the design, implementation and evaluation of integrated STEM curriculum. In our discussion of the S-T-E-M Quartet, we have argued for the centrality of complex, persistent and extended problems to reflect the authenticity of real-world issues and hence, the need for integrated, as opposed to monodisciplinary, STEM education. Building upon this earlier work, we propose two additional variationsjsolution-centric and user-centric approachesjto the provision of integrated STEM curricular experiences to afford more opportunities that address the meta-knowledge and humanistic knowledge developments in 21st century learning. These variations to the S-T-E-M Quartet aims to expand the scope and utility of the framework in creating curriculum experiences for diverse profiles of learners, varied contextual conditions, and broad STEM education goals. Collectively, these three approachesjproblem-centric, solution-centric, and user-centricjcan afford more holistic outcomes of STEM education.
A laser-cutting-centered STEM course for improving engineering problem-solving skills of high school students in China
Authors: Cai Ruiheng , Chiang Feng-kuang
Published: August 2021

STEM (science, technology, engineer, mathematics) education and engineering education are receiving an increasing amount of interest worldwide, but related research on the influence of STEM courses on students' engineering problem solving in China is scarce. Considering the rapid prototyping function of laser-cutting tools, this study was conducted to develop a STEM course based on laser cutting and to explore how the course affected high school students' engineering problem-solving abilities. A 9-week curriculum was implemented in a science, technology, and fabricating club of a high school in Zhejiang, China. The data were collected by pretest and posttest questionnaires and presentations of group assignments. The results were as follows. First, when presented with an engineering problem, the students demonstrated problem-solving abilities because they followed principles of engineering design, such as sketching, modeling and modifying. Second, while completing the assignment, the students proposed solutions with comprehensive factors in many aspects. They showed high-level thinking, such as consideration of the background, limiting conditions, and multidisciplinary knowledge, and they used technological tools to complete the task. However, some students ignored the assessment and redesign of their solutions. Further research could use a larger sample from different grades and explore how a STEM course combined with technology tools could influence students' high-level thinking skills.
Gestion des deux langues en classe bilingue : analyse comparative en Alsace et en Bretagne

Published: August 2021

L’insegnamento bilingue francese-lingua regionale nel ciclo primario richiede all’insegnante di mettere in atto pratiche pedagogiche particolari al fine di insegnare in lingua regionale ad alunni spesso principianti nella lingua regionale in questione. La ricerca di pratiche didattiche dei professori che insegnano nelle due lingue nelle loro classi (1 insegnante – 2 lingue) in Alsazia e in Bretagna mette in luce pratiche, ma anche motivazioni molto diverse nelle due regioni. Questo studio permette di rivedere il posto della L1 e più in generale la visione stessa di quello che è un insegnamento bilingue, piuttosto considerato come due monolinguismi paralleli in Alsazia e trattato invece in un’ottica più bi-plurilingue in Bretagna.

Nearly no organizational phenomenon has garnered as much attention as organizational change. It appears as one of the fascinating and nearly eroticizing inducements for business organizations, and it has been highly acknowledging as a response. Highlighting the importance this phenomenon holds in the current environment, there is a huge and still growing body of research concentrating on organizational change. This chapter briefly explains the overview of the three major organizational change approaches (teleological approaches and evolutionary approaches and psychological approaches), which highlight organizational change through different models and theories.
Innovation Leading Organizations
Authors: Nogueira André , Agua Pedro B. , Correia Anacleto C.
Published: August 2021

Innovation is one of the most likely factors to boost effectiveness, efficiency, and sustainability of an organization, regardless of its sector of activity, as for instance, the armed forces. The absence of innovation can affect the organizations in different ways, from suboptimal operational effectiveness and improvement of organization processes (administrative, operational, or logistics), bringing with it negative impacts on human resources motivation – the main keepers of knowledge, institutional culture, and organizational values. Innovative organizations also generate a stronger sense of belonging across their ranks and structures and fosters effectiveness in fulfilling organizations' missions. Hence, fostering innovation across any typology of organization is crucial and requires a proper approach to promote the desirable involvement of the entire workforce. This text, based on a review of some relevant literature, exposes critical enabling factors. Based on a cause-and-effect analysis, it proposes some recommendations for the practitioner as well as the academic.
Following Through the Good and the Bad?
Authors: Crawford Joseph , Young Sarah M. , Knox Matthew Wayne
Published: August 2021

Followers are underrepresented in the organizational change literature despite their considerable influence on change success. Politics, culture, motivation, communication, and readiness have a large impact on change success, and these influences are examined in the change context. Each of these are influenced by leaders and followers. The role of authentic followers in enabling positive change through their organizational engagement is explored in depth. This chapter demonstrates that while the influential role of leaders in change is established, the authentic follower represents a large body of potential change agents with the capacity to positively influence the success of change. Many behaviors of the authentic follower make them an ideal candidate for this role, including moral potency, high levels of engagement in organizational structure, and flexibility. Further research highlighting the value of the authentic follower is warranted.
Relations and Distance Schooling
Authors: Crescenza Giorgio
Published: August 2021

Due to the unprecedented period which has swept over educational agencies, as well as society as a whole, it is appropriate to try to learn and understand the first effects of these transformations operating on different levels: educational, formative, relational, and social. This contribution intends to develop some reflections on the different dimensions which have affected more than others the educational, formative, and scholastic experience, paying particular attention to the educational relationship and the modifications in teaching. The analysis takes as its starting point some empirical data from an exploratory study at the Università degli Studi Roma Tre. The role of the school on the path of cultural humanisation of the human being is then presented, followed by a critical discussion on how the teaching and relational changes that have inevitably been introduced this year fit into this path. Lastly, the conclusion considers how to transform the crisis which has struck schools at the heart into an opportunity for thinking about them with a wider perspective.

Does the Food Safety Ranking System Act as a Nudge?
Authors: Awasthi Bhuvanesh
Published: August 2021

Public health safety is of concern to authorities across the globe, and inspector's food hygiene ranking system has been introduced in many countries. Mandatory disclosure of hygiene ranking information was introduced to empower consumers to make informed decisions regarding foodborne risks. Evaluating available research on public perception and attitude towards such rankings, it seems that the food safety rankings may prompt hygiene compliance by the food business operators and may act as a nudge for consumers to avoid outlets, though with certain caveats. Significant assessment of the scheme remains to be carried out for the ranking system to be an effective nudge for sustainable consumer protection. The public health authorities and organisations need to consider several real-world cognitive and behavioural constraints.
An Advanced Morphological Component Analysis, Steganography, and Deep Learning-Based System to Transmit Secure Textual Data
Authors: Pandey Binay Kumar , Pandey Digvijay , Wairya Subodh , Agarwal Gaurav
Published: August 2021

A potential to extract detailed textual image texture features is a key characteristic of the suggested approach, instead of using a single spatial texture feature. For the generation of MCs, four textured characteristics (including horizontal and vertical) are assumed in this paper that are content, coarseness, contrast, and directionality. The morphological parts of a clandestine text-based image were further segmented and then usually inserted into the least significant bit in cover pixels utilising spatial steganography. This same reverse process for steganography and MCA is conducted on the recipient side after transmission. The results demonstrate that the proposed method based on fusion of MCA and steganography provides a higher performance measure, for instance peak signal-to-noise ratio, SSIM, than the previous method.

Minecraft in Education Benefits Learning and Social Engagement
Authors: Alawajee Omar , Delafield-Butt Jonathan
Published: August 2021

Empirical evidence suggests game-based learning (GBL) as a potentially engaging form of contemporary learning. With the increase in the use of Minecraft, a sandbox computer game in open-world format, there has been a concurrent rise in the level of interest in investigating the role of Minecraft in social and academic learning. Minecraft is socially interactive, and its cooperative, rather than competitive, open-world gameplay suggests that it could be used for educational purposes. This paper presents a systematic review of all published peer-reviewed research and synthesises the evidence for and against Minecraft's use in education to better understand the applicability of Minecraft in educational and psychological interventions. Forty-two papers were identified. These revealed Minecraft to be beneficial in terms of increased motivation, language development, and academic learning in subjects such as science and history. Minecraft play also supported the development of social skills, including communication, sharing, collaboration, and leadership. Concerns about age-appropriateness, safety, technology use, and learning generalisation were raised, but on balance, the evidence favours an informed and guided employment of Minecraft for improved opportunities for learning and engagement in education.

However, many companies are struggling to realize the digital transformation due to various existing barriers. They face many obstacles in the development and implementation of new digital processes. In cases where the companies fail to reflect upon these barriers, digital transformation processes carry the risk of not being realized successfully. Therefore, this study has looked to identify the barriers in digital transformation, in a company in the IT sector in Sweden. The data was collected through semi-structured interviews with the team members involved in digital transformation and from the company's documents, and then thematically analyzed. The findings of this research study are that there are 28 barriers in digital transformation from which 15 are new barriers that could support executives and managers who are planning a digital transformation in their organizations.
Knowledge Diversity and Employee Outcomes
Authors: Haque Md Jamirul
Published: August 2021

This research investigates the impact of perceived knowledge diversity (PKD) on job outcomes such as job satisfaction (JS) and job performance (JP). Next, this study also explores the moderating role of workforce diversity management (WFDM) on the relationship between PKD and employee job outcomes (EJO). SPSS and AMOS-SEM are used to analyze the data. The findings show that PKD is positively related to JS and negatively associated with JP. WFDM moderates the relationship between PKD and EJO (JS and JP). There are many studies related to diversity and its management, but most of the studies are from an American perspective that deals with diversity related to age, gender, race, ethnicity, etc. (surface-level diversity). The study in diversity in knowledge, value, personality, belief, etc. (deep-level diversity) is scanned in the literature. This study aims to address this void, particularly investigating knowledge diversity in research by establishing how WFDM moderates the relationship between PKD and employee outcomes.

Authors: McLester Quatavia , Burrell Darrell Norman , Nobles Calvin , Castillo Ileana
Published: August 2021

Sexual harassment remains prevalent in the workplace as well as a significant financial burden for organizations. Given the cost associated with sexual harassment, reputational damage, and internal disturbances, sexual harassment is a mounting apprehension because senior managers are responsible for bestowing an organizational culture that is intolerant to such engrossed behavior. It is imperative to explore how workplace stories and office talk are influenced by organizational culture and how organizational culture affects the workers' perceptions of Me Too and consequences of sexual harassment. Understanding the phenomenon of sexual harassment at work is vital to shaping organizational culture, behavior, and policies aimed at reducing sexual misconduct at work. Existing research indicates that 81% of women and 43% of men have experienced an aspect of sexual harassment. This study uses a content analysis exploration of the literature to better understand the impact and solutions to sexual harassment in the workplace.

Due to the difficulty in the selective synthesis of semiconductor (s-) and metal (m-) single-walled carbon nanotubes (SWCNTs), we still need to explore the selective extraction technology of s-SWCNTs. Using Poly[9-(1-octylonoyl)-9H-carbazole-2,7-diyl] (PCz) extraction of s-SWCNTs has attracted extensive attention in recent years, because it can selective extraction of large-diameter s-SWCNTs with high purity. However, influence of the molecular weight of this polymer on the s-SWCNTs selective extraction properties remains unclear. In this study, we used PCz with different average molecular weights to study the ability of selective extraction s-SWCNTs from pristine arc discharge carbon nanotubes. Spectra studies indicate that compared to the PCz with lower molecular weight, the PCz with higher molecular weight has better selective extraction ability, and can help to obtain s-SWCNTs with higher purity (>99%) and high yield. FETs devices have been prepared by s-SWCNTs obtained via PCz with higher molecular weight exhibit higher on/off ratio, lower off current and lower subthreshold swing. This work offers a reference of the design and synthesis of PCz polymer that performs sufficient selective ability in extracting s-SWCNTs with promising applications.

The purpose of this work was to study and further clarify the anti-wear and anti-friction mechanism of ultrafine SiO2/MoS2 powders in the complex calcium sulfonate grease. In this paper, 15nm nanoSiO2, 1μm MoS2 and commercial NLGI Grade No.2 complex calcium sulfonate grease were used as the research objects, SEM, EDS and XPS were used to study the morphology, composition and film chemical constitution of the long friction wear spots of grease containing single nanoSiO2 powder, ultrafine MoS2 powder and the two compound powders, which formed in the process of four ball long friction. The results show that nanoSiO the grease plays a role in filling the undercut, ball bearings and polishing and forming high hardness Ca3Fe2(SiO4)3 and part of Fe2O3 anti-wear films in the process of long friction. The ultrafine MoS2 powder has a self-repairing effect to fill the grooves,forming the MoS2, MoO3 anti-friction films and Fe2(SO4)3 anti-wear film. The two powders in the composite grease have a synergistic effect, acting on the friction pair together, and simultaneously forming self-repairing anti-friction and anti-wear films, thereby further improving the tribological performance of the base grease.

Products from an arc discharge between various conducting materials (copper-copper, graphite-graphite, natural graphite and their combination) in water and air have been studied. The SEM and SEM-EDS analysis, and the BET analysis on products from discharges were done as well identifying their size distribution. There are two essential types of product taken in investigation as (i) pure metallic particulates, and (ii) specific structures of materials. The visual properties of nano-sized products formed in two media at different current are compared. In products obtained in air, tiny spherical particulates of size in nano-order are observed repeatedly, as well ordinary nano-sized particulates as ones in water. The main visual feature of the particulates formed in air is their existence in deposition in which they are separated by itself. Plenty of individual scrolling sheets of graphite layer of enormous size frequently encounter in soot on electrodes.

We have calculated the energies of excited states for the He, Li, and Be atoms by the time dependent self-consistent Kohn Sham equation using the Coulomb Wave Function Discrete Variable Representation CWDVR) approach. The CWDVR approach was used the uniform and optimal spatial grid discretization to the solution of the Kohn-Sham equation for the excited states of atoms. Our results suggest that the CWDVR approach is an efficient and precise solutions of excited-state energies of atoms. We have shown that the calculated electronic energies of excited states for the He, Li, and Be atoms agree with the other researcher values.

The surface structure of the WSe2 were studied using scanning tunneling microscopy. Exfoliation method in an ultra-high-vacuum chamber method is used to obtain a clean surface of WSe2 samples with atomically smooth terraces and multi-layer steps. Atomic-resolution images revealed two types of atomic defects of surface or near surface. These defects have been identified as the defects in the tungsten atom layer just below the topmost selenium layer.

First-Principles Study of Carrier-Mediated and Vacancy-Induced Ferromagnetism in Molybdenum Disulfide Monolayer
Authors: Tsogbadrakh Namsrai
Published: August 2021

We have investigated the magnetic properties of semiconducting molybdenum disulfide (MoS2) monolayer (ML) using the plane wave self-consistent field (PWscf) method within the framework of density functional theory (DFT). The pristine semiconducting bulk MoS2 is nonmagnetic (NM), due to the spin pairing of two electrons. We have indicated that the carrier-mediated ferromagnetism is available on the MoS2 ML as both the hole and electron carriers. The ordinary neutral S (VS0) vacancy creates the localized vacancy defect level and this level does not create the ferromagnetic (FM) state due to the spin pairing of two electrons by three Mo dangling bonds. While we have shown that the FM state is possible to create the FM state, due to the additional hole and electron carriers on the valency band and localized vacancy defect level by positively and negatively charged S (VS1+ and VS1- ) and positively charged Mo (VMo1+) vacancies.

Recently, Far-infrared Light Emitting Diodes have attracted considerable interest in the research field worldwide. Emerging light therapy requires effective red/far-infrared light resources in clinical and plant photomorphogenesis to target or promote the interaction of light with living organisms. Here, Gd3Al4GaO12:Cr3+ (hereinafter referred to as: GAGG:Cr3+) phosphor was synthesized by high-temperature solid-phase method, and the crystal structure, morphology, and luminescence properties of this series of phosphor samples were studied. Through X-ray powder diffraction to obtain pure phase GAGG:Cr3+ series phosphor. Under the excitation of 420nm blue light, a broad band emission from 640 to 850nm is obtained, which is the result of the transition of Cr3+ 4T2→4A2 level. A sharp emission peak at 693nm is the R line belonging to Cr3+ in Gd3Al4GaO12 garnet. R line is assigned to the spin-forbidden 2E→4A2 transitions of Cr3+ ions that occupy the ideal octahedral sites. As the Cr3+ doping concentration increases, the luminous intensity of the sample increases first and then decreases. When the doping concentration of Cr3+ is 0.1mol phosphor,the luminous intensity is strongest at one single broad peak at about 712nm. At 440k, the R sharp line (693nm) and broad band (712nm) emission intensity maintained 78.6% and 71.8% , compared to room temperature intensity, respectively. The change of fluorescence lifetime at different temperatures gives the mechanism of fluorescence change with temperature. The current exploration will pave a promising way to engineer GAGG:Cr3+ activated optoelectronic devices for all kinds of photobiological applications.

Published: August 2021

The Sustainable Development Goals (SDGs) have been much debated but there is no question that their goal is to achieve a more balanced and sustainable planet. This study systematically reviewed literature in order to determine the key criteria needed to implement such goals. A search of Scopus indexed journals as well as grey literature published up to March 2020 yielded 114 papers for examination. Using a Network Theory approach, the study found 14 common criteria for successful policy integration of the SDGs. The findings from this paper support that the achievement of the SDGs needs a comprehensive and holistic approach to achieve them. Through an assessment of many different fields of study, commonalities or networks occurred demonstrating how one goal can support and be a means to an end to achieve another. Conclusions consider that using Network Theory to assess tourism policies may assist in the success of policies for the achievement of the SDGs due to its interrelated nature.
