Authors: Musa Siti Nur Syuhada , Hamzah Siti Raba’ah , Asimiran Soaib , Muda Zulaiha
Published: April 2021

This study investigated the antecedents of work engagement of Malaysian employees who were cancer survivors. Work engagement refers to a positive, fulfilling, work-related state of mind characterizing employees who work hard and persist despite difficulties. Employees with high levels of work engagement are deeply involved in what they do and are happily absorbed in their work. This study was aimed to examine the individual and work environment-related factors that influence work engagement. A quantitative research paradigm was adopted, with a cross-sectional design using data collected from cancer survivors registered at the Hospital Kuala Lumpur. The 270 participants in this study were randomly selected by inclusive criteria sampling. A validated instrument was tested in a pilot study. Partial Least Square-Structural Equation Model (PLS-SEM) was used to test the direct effects of work engagement. It was found that the level of all the tested variables (work engagement, employee resilience, social support, and quality of working life) among the participants were high. This study highlights the importance of resilience and social support in improving work engagement among cancer survivors in Malaysia.
THE AWARENESS OF THE MUSLIMS TOWARDS THREATS OF MODERN IDEOLOGY: A STIPULATION
Authors: Haji Yusoff Ahmad Mujahideen , Yaacob Muhammad Nasron , Mohamed Hussin Norhidayah
Published: April 2021

Muslims to this day still face the challenges of modern ideology for a relatively long period of time. The emergence of modern ideologies such as secularism, liberalism, pluralism, and others became a great disaster that could erode the faith of Muslims towards Islam itself. Therefore, this article discusses the concerns of Muslims towards the threat of modern ideology which is a necessity today. This article is fully qualitative using data collection and data analysis methods involving library methods from printed materials using N-Vivo 2.0 software. This article finds that the beliefs of Muslims are increasingly threatened because some Muslims themselves prefer to choose modern ideology as a social style in life rather than Islamic teachings. They are based on modernity and the need for modern progress which indirectly causes Islam to become increasingly alienated from the core beliefs of Muslims. Therefore, Muslims need to be mobilized again to realize the threats and dangers of this modern ideology and return to the practice of the true religion of Islam.
Impact of heat treatment process on threshold current density in AlGaN-based deep-ultraviolet laser diodes on AlN substrate

Published: April 2021

The electroluminescence (EL) uniformity of AlGaN-based deep UV laser diodes on AlN substrate was analyzed by using the EL imaging technique. Although nonuniform EL patterns were observed, the uniformity was improved by changing the position of the p-electrode. The threshold current density was also reduced by suppressing the inhomogeneity of the EL. Cathodoluminescence analysis revealed that the cause of the non-uniformity is the degradation of the active layer and the nonuniformity emission formed by rapid thermal annealing at high temperature after mesa structure formation.

Published: April 2021

For nearly 100 years, American leadership, regardless of political affiliation, has recognized the vital importance of people-to-people international exchange programs in bolstering our nation’s economy, strengthening our national security, and improving America’s status in the world. In today’s interconnected world, where global challenges require global cooperation on solutions, the United States should not retreat from international engagement, but should rather double our efforts to build positive and mutually supportive connections with our neighbors. America must embrace its role in leading international peace and prosperity by facilitating meaningful, safe, educational exchange in all directions – helping more Americans learn firsthand about other people and cultures and helping more foreign students come to America to experience for themselves the principles upon which our country was built - liberty, democracy, capitalism, and basic human freedom. America can and should leverage international education, exchange and public diplomacy programs to plant seeds of peace, regain the world’s trust, and return to our previous role as a respected leader in global affairs. Leading the effort to bring the world together helps America, Americans, and our vital allies.

Published: April 2021

Background: Sickle cell disease (SCD) is a genetic condition affecting primarily individuals of African descent, who happen to be disproportionately impacted by poverty and who lack access to health care. Individuals with SCD are at high likelihood of high acute care utilization and chronic pain episodes. The multiple complications seen in SCD contribute to significant morbidity and premature mortality, as well as substantial costs to the healthcare system.

Objectives: SCD is a complex chronic disease resulting in the need for primary, specialty and emergency care. Many providers do not feel prepared to care for individuals with SCD, despite the existence of evidence-based guidelines. We report the development of a SCD toolbox and the dissemination process to primary care and emergency department (ED) providers in North Carolina (NC). We report the effect of this dissemination on health-care utilization, cost of care, and overall cost-benefit.

Methods: The SCD toolbox was adapted from the National Heart, Lung, and Blood Institute recommendations. Toolbox training was provided to quality improvement specialists who then disseminated the toolbox to primary care providers (PCPs) affiliated with the only NC managed care coordination system and ED providers. Tools were made available in paper, online, and in app formats to participating managed care network practices (n=1800). Medicaid claims data were analyzed for total costs and benefits of the toolbox dissemination for a 24-month pre- and 18-month post-intervention period.

Results: There was no statistically significant shift in the number of outpatient specialty visits, ED visits or hospitalizations. There was a small decrease in the number of PCP visits in the post-implementation period. The dissemination resulted in a net cost-savings of $361 414 ($14.03 per-enrollee per-month on average). However, the estimated financial benefit associated with the dissemination of the SCD toolbox was not statistically significant.

Conclusions: Although we did not find the expected shift to increased PCP visits and decreased ED visits and hospitalizations, there were many lessons learned.

Published: April 2021

Objectives: Early microvascular damage and dysfunction are clinically mirrored in Raynaud’s phenomenon (RP). Currently, nailfold capillaroscopy (NC) is applied to differentiate between primary RP (PRP) and secondary RP (PRP), associated with connective tissue disease. However, abnormal morphology can also be caused due to age-related changes and cardiovascular disease. Thermography (TG) is a non-invasive technique which enables quantification of cutaneous vascular function. An approach using both NC and TG could improve the differentiation between PRP and SRP.

Methods: Thirty RP patients (PRP, n = 21; SRP, n = 9) underwent nailfold capillaroscopy and thermography. Morphologic features were scored and patients were categorized according to the guidelines of EULAR Study group on Microcirculation in Rheumatic Diseases. TG of the hand was performed before, directly and ten minutes after a cold challenge test. Baseline images and rewarming curves were analyzed.

Results: Capillary abnormalities with NC were found in all SRP patients (9/9) and in 48% (10/21) of PRP patients. Out of 10 PRP patients with altered capillary morphology, 9 (90%) had a cardiovascular disease. For all patients mean temperature was significantly higher 10 minutes after cold induction than before (p < 0,01). The gradient of the rewarming curve was significantly lower in patients with SRP compared to PRP patients (p = 0.015).

Conclusions: Nailfold capillaroscopy and thermography can reliably be used to measure microvascular damage and dysfunction. Additional thermography can assist in differentiating between PRP and SRP, especially in elderly patients or in presence of a cardiovascular disease.

Keywords: Raynaud’s phenomenon; Nailfold capillaroscopy; Thermography

Published: April 2021

The research over the past decade demonstrates that modern technology have incredibly changed the communication habits – more than ever before, however they differ between generations. The research shows that the views on the role and importance of education also significantly differ between the generations, thus the change of communication habits can potentially lead to conflict situations between students and teachers. The aim of this study is to determine the differences between the desired communication methods based on the common generational distance in Latvian schools between students and teachers: Baby Boomer Generation (BP), born between 1946–1964, Generation X (XP), born between 1965–1980, and Generation Z (ZP) born between 1996-2010. For the research purposes, a semi-structured interview was developed and three research questions were analysed, and as a result it was concluded that there are statistically significant differences between generations in their preferred forms of communication – the younger the generation, the more technology-mediated communication is employed. It was found that the teachers prefer using technology-mediated communication more in business communication setting, but the younger generation often does it also in the context of personal communication. The study found that there are no statistically significant differences between generations in the perceived quality of communication. These results suggest that a potential split is possible between perception of communication between students and teachers. The additional research would be necessary on the perception of the distance-learning situation among all participants in the educational process.

Tieteen muuttuva rooli korporatistisessa neuvonannossa
Authors: Holli Anne Maria , Turkka Saara
Published: April 2021

Kysymys tutkijoiden ja tieteellisen tiedon roolista poliittisen päätöksenteon valmistelussa on viime vuosina puhuttanut niin tiedeyhteisöjä kuin julkispolitiikan toimijoitakin. Tässä artikkelissa analysoidaan ajallisen pitkittäisanalyysin avulla tutkijoiden osallistumista suomalaisittain keskeisiin päätöksenteon valmistelun instituutioihin, valtionkomiteoihin ja ministeriöiden laajapohjaisiin valmistelutyöryhmiin, vuosina 1980–2018. Suomessa, kuten muissakin Pohjoismaissa, yhteiskunnallisesti tärkeämmät päätökset on perinteisesti valmisteltu korporatistisissa valmisteluelimissä, joihin on nimitetty viranhaltijoiden ohella myös etu- ja kansalaisjärjestöedustajia sekä tutkijoita.

 

Tutkimuksessa hyödynnetään sekä primääri- että sekundääriaineistoa tutkijoiden osallistumisesta komitea- ja työryhmätyöskentelyyn kyseisellä ajanjaksolla. Tulokset osoittavat, että tutkijoiden osuus työryhmissä on 2010-luvulla yli puolittunut edelliseen vuosikymmeneen verrattuna, samalla kun heidän asemansa työryhmien sisäisessä hierarkiassa, erityisesti niiden puheenjohtajina, on heikentynyt. Suomessa ei näin ollen ole tapahtunut joissakin muissa Pohjoismaissa havaittua ”tieteellistymiskehitystä”, jossa tutkijoiden määrä valmistelukorporatismin instituutioissa on kasvanut, vaan pikemminkin päinvastoin. Tutkimustulokset kertovat Suomen poliittisen neuvonantojärjestelmän hybridisoitumisesta. Valtiovallan tavat kerätä ja hyödyntää tietoa päätöksenteon valmistelussa ovat muuttuneet, samalla kun laajapohjaisia työryhmiä asetetaan harvemmin. Nämä tekijät ovat työntäneet tutkijoita valmisteluinstituution ulkopuolelle, ja he ovat menettämässä asemaansa korporatistisina kumppaneina. Poliittisen neuvonannon muotojen moninaistuminen on puolestaan vetänyt tutkijoita uudentyyppisiin valmistelua tukeviin rooleihin. Viime vuosien kehitys näyttää vahvistaneen erityisesti neuvonantojärjestelmän uusliberaaleja piirteitä.
A Crystallographically Supported Equation for Calculating Water in Emerald from the Sodium Content
Authors: Henry Rhiana E. , Groat Lee A. , Evans R. James , Cempírek Jan , Škoda Radek
Published: April 2021

Emerald is the most well-recognized beryl (Be3Al2Si6O18) variety, and although it has been extensively studied, a satisfactory method for quantifying the water content within the structural channels of the crystal lattice has yet to be proposed. Water is frequently present in the structural channels of beryl and can occur in two orientations (Type I and Type II). While spectroscopic methods are ideal for determining the orientation of the water molecules, measuring the overall water content often requires expensive or destructive analytical techniques. Sodium is necessary to charge-balance divalent cation substitutions at the Al site of beryl; it is also correlated with H2O in the structural channels, which typically occurs as Type II water. In this study, we present equations that can be used to easily calculate the H2O content of an emerald beryl with significant Na+ content based on either Na+apfu or Na2O weight percent. Unlike previous work, these equations are derived from single-crystal X-ray diffraction data which can be used to accurately measure both the Na+ and H2O contents. We checked the validity of the data using electron probe microanalyses for elements heavier than O. We compared the results with hypothetical scenarios in which different cation substitutions are prevalent, as weight percentages are variable based on the elemental contents. Our results indicate that Na+ or Na2O weight percent can be used to calculate H2O content in emerald beryl with reasonable accuracy, which will allow future researchers to use a simple calculation instead of expensive or destructive techniques when determining H2O content in emeralds.

Authors: Schwarz Jochen , Beinersdorf Silke , Meidow Hein
Published: April 2021

Der Geologe und Seismologe Prof. Dr. Ludwig Ahorner (1930–2007) leitete insgesamt 35 Jahre lang (bis 1995) die Erdbebenstation Bensberg und die spätere Abteilung für Erdbebengeologie am Geologischen Institut der Universität zu Köln. Nicht zuletzt mit der systematischen Aufbereitung der historischen und aktuellen Erdbeben-Basisdaten und ihrer kontinuierlichen Pflege in Form eines magnitudenorientierten Erdbebenkatalogs hat Ahorner für das Erdbebeningenieurwesen und in konkreten Anwendungsaufgaben verdienstvoll bleibende Anerkennung erworben.

 

Nach mehrjährigen (in der Anfangsphase von Ahorner noch begleiteten) Forschungsarbeiten und in Zwischenversionen vorgelegten Überarbeitungen wird der „Ahorner-Katalog“ in umfänglicher Erweiterung für die Erdbeben in deutschen und im 50 km Randbereich angrenzenden Gebieten im Zeitfenster der Jahre 880 bis 2013 als Buch herausgegeben.

CO2-freie Wärme als langfristige Kapitalanlage
Authors: Fluch Jürgen , Schmitt Bastian , Pag Felix , Trabert Ulrich , Schlosser Florian
Published: April 2021

SOLARTHERMIE | Der deutsche Endenergieverbrauch entfällt zu mehr als 28 % auf die Industrie, dies entspricht in etwa 720 TWh im Jahr. Hiervon sind mehr als zwei Drittel auf die Wärmebereitstellung zurückzuführen, die in der Regel auf fossilen Energieträgern basiert [1]. Zur Erreichung der Klimaschutzziele von Paris sind zwingend die Potenziale zur Steigerung der Energieeffizienz zu erschließen. Hand in Hand damit geht die Integration CO2-armer Technologien wie Solarthermie, um die notwendige Dekarbonisierung industrieller Wärmeversorgungsstrukturen voranzutreiben.
Vorteile unterirdischer Pelletspeicher nutzen
Authors: König Klaus W.
Published: April 2021

BIOMASSE | Holzpelletheizungen werden wie andere regenerative Techniken vom Staat gesetzlich gefordert, aber auch finanziell gefördert. Das schafft Anreize und gleicht Mehrkosten bei der Investition aus – zum Beispiel für einen unterirdischen Speicher des Brennstoffs. Niedrige Betriebskosten machen die Anlage rentabel. Dafür sorgen der gegenüber Gas und Öl dauerhaft günstige Preis der Holzpellets und eine störungsfreie Funktion der Anlage – vorausgesetzt, dass fünf typische Fehler beim Außenspeicher vermieden werden.

Wie hoch ist der Umsatz tatsächlich? Und welche Risiken müssen in der Bilanz berücksichtigt werden? Energieversorgungsunternehmen (EVU) werden bei der Ermittlung von Kennzahlen mit einigen Unschärfen konfrontiert: Rollierende Ablesung, Preisrisiken aus Ausgleichsenergie und Mehr- und Mindermengen sowie der zeitliche Versatz bis zur Abrechnung von Mehr- und Mindermengen beispielsweise bergen Risiken. Transparenz schafft ein regelkreisbasiertes Monitoring. Damit lassen sich die voraussichtlichen Abweichungen von den Planzahlen mathematisch bestimmen und unangenehme Überraschungen vermeiden.
Explaining face-voice matching decisions: The contribution of mouth movements, stimulus effects and response biases
Authors: Lavan Nadine , Smith Harriet , Jiang Li , McGettigan Carolyn
Published: April 2021

Previous studies have shown that face-voice matching accuracy is more consistently above chance for dynamic (i.e. speaking) faces than for static faces. This suggests that dynamic information can play an important role in informing matching decisions. We initially asked whether this advantage for dynamic stimuli is due to shared information across modalities that is encoded in articulatory mouth movements. Participants completed a sequential face-voice matching task with (1) static images of faces, (2) dynamic videos of faces, (3) dynamic videos where only the mouth was visible, and (4) dynamic videos where the mouth was occluded, in a well-controlled stimulus set. Surprisingly, after accounting for random variation in the data due to design choices, accuracy for all four conditions was at chance. Crucially, however, exploratory analyses revealed that participants were not responding randomly, with different patterns of response biases being apparent for different conditions. Our findings suggest that face-voice identity matching may not be possible with above-chance accuracy but that analyses of response biases can shed light upon how people attempt face-voice matching. We discuss these findings with reference to the differential functional roles for faces and voices recently proposed for multimodal person perception.
Interleaved practice benefits implicit sequence learning and transfer
Authors: Schorn Julia M. , Knowlton Barbara J.
Published: April 2021

Compared to blocked practice, interleaved practice of different tasks leads to superior long-term retention despite poorer initial acquisition performance. This phenomenon, the contextual interference effect, is well documented in various domains but it is not yet clear if it persists in the absence of explicit knowledge in terms of fine motor sequence learning. Additionally, while there is some evidence that interleaved practice leads to improved transfer of learning to similar actions, transfer of implicit motor sequence learning has not been explored. The present studies used a serial reaction time task where participants practiced three different eight-item sequences that were either interleaved or blocked on Day 1 (training) and Day 2 (testing). In Experiment 1, the retention of the three training sequences was tested on Day 2 and in Experiment 2, three novel sequences were performed on Day 2 to measure transfer. We assessed whether subjects were aware of the sequences to determine whether the benefit of interleaved practice extends to implicitly learned sequences. Even for participants who reported no awareness of the sequences, interleaving led to a benefit for both retention and transfer compared to participants who practiced blocked sequences. Those who trained with blocked sequences were left unprepared for interleaved sequences at test, while those who trained with interleaved sequences were unaffected by testing condition, revealing that learning resulting from blocked practice may be less flexible and more vulnerable to testing conditions. These results indicate that the benefit of interleaved practice extends to implicit motor sequence learning and transfer.
