EXEMPLARY: Peran Keluarga dalam Membangun iman anak dan Fungsi sekolah dalam membentuk karakter
Authors: toromoeadrianvalerius@gmail.com
Published: May 2022

The family is the smallest unit in society, where the family consists of father, mother, grandfather, grandmother, brother, sister. Although in a small scope, the relationships that are built between family members are closer and more intimate. This is because the family is a group of people who are bound by blood relations. No wonder, if the family is called the best support system. Where between family members will give each other good and full support in all conditions. The family is formed from human marriages united by God and obeying God's law. As the word of God says: "it is not good, if man is alone. I will be a helper for him, worthy of him (Gen. 2:18). By understanding the meaning of family, it can provide a wider perspective in seeing the role of each family member. That way, each member can give responsibility and get proper rights in the family. In the family we can find advice, leading us to the right path. In addition to the school and church families are also involved.

Published: May 2022

Debris flows are dense and fast-moving complex suspensions of soil and water that threaten lives and infrastructure. Assessing the hazard potential of debris flows requires predicting yield and flow behavior. Reported measurements of rheology for debris-flow slurries are highly variable and sometimes contradictory, due to heterogeneity in grain size, shape, chemical composition, and solid-volume fraction (ϕ). Here we examine the composition and flow behavior of source materials that formed the post-wildfire debris flows in Montecito, CA in 2018, for a wide range of ϕ that encapsulates debris-flow formation by overland flow. We find that shear viscosity and yield stress are controlled by the distance from jamming, ∆ϕ = ϕm − ϕ, and that the jamming fraction ϕm depends on grain-size polydispersity and friction. By re-scaling shear and viscous stresses to account for these effects, the data collapse onto a simple non-dimensional flow curve indicative of a Bingham plastic (viscoplastic) fluid. Given the highly nonlinear dependence of rheology on ∆ϕ, our findings suggest that determining the jamming fraction for natural materials will significantly improve flow models for geophysical suspensions such as hyperconcentrated flows and debris flows.
“Weird duality”: Learning from peer mentors’ experiences of supporting student mental health during the COVID-19 pandemic
Authors: Berry Clio , Phelan Emma , Michelson Daniel
Published: May 2022

Objectives: To explore the experiences of university peer mentors in the pandemic context and apply participatory methods to co-produce recommendations for practice. Participants: Thirteen peer mentors from varied undergraduate and postgraduate mentoring programmes in one university in South-East England.Methods: A two-phase qualitative design involving individual interviews and a focus group, followed by a participatory action group with a subset of phase 1 participants. Results: Peer mentors identified an increasing student need for mental health support during the Covid-19 pandemic. However, engaging with prospective mentees was a challenging process for many participants. Peer mentors assumed multiple roles. Mentor-mentee relationship were characterised by intimacy and mutuality, which were seen as conducive to providing authentic support but also presented significant challenges in negotiating boundaries. Conclusions: Peer mentoring is a complex activity, characterised by a sense of multiplicity and mutuality. Peer mentors require greater supervision and training to manage these complexities.
Naturally Green, Irrationally Lean: How Background Scenery Affects Calorie Judgments
Authors: Folwarczny Michal , Otterbring Tobias , Sigurdsson Valdimar , Tan Lynn K. L.
Published: May 2022

The calorie content of food plays a pivotal role in shaping consumers’ food choices. Previous research indicates that consumers often base their calorie judgments of food on seemingly superficial cues present in the environment in which they make their evaluations. For example, the addition of vegetables to a meal induces a “health halo,” thereby lowering the perceived calorie content of the entire dish. We examine whether environmental cues communicating naturalness may trigger such a “halo” effect. Specifically, we test whether meals accompanied by a natural (vs. urban) environment are estimated to be lower in their calorie content. Although recent research has found no association between eating environments and consumers’ calorie judgments, we propose that these null findings may have emerged at least in part as a result of the failure to consider a critical moderator: the perceived healthiness of the food. Consistent with this notion, a mixed (between-within-subjects) design experiment reveals that participants estimate the total calorie content of meals as lower when such evaluations are carried out in a natural (vs. urban) environment, but only for foods rated as relatively unhealthy and not for food rated as relatively healthy. Overall, our results highlight the moderating role of perceived food healthiness when studying the effects of environmental cues on consumers’ calorie judgments.

IntroductionChildhood adversity is a major risk factor for psychiatric disorders and has especially been associated with an admixture of depressive, anxiety and psychosis symptoms. Identity formation, a main developmental task during adolescence, may be impacted by these adverse experiences and act as an important process in the association between childhood adversity and psychopathology.MethodsWe investigated the association between childhood adversity, identity formation, and depressive, anxiety and psychosis symptoms cross-sectionally in 1913 Flemish adolescents between 11 and 20 years old (mean = 13.76, SD = 1.86). Adolescents completed questionnaires during the first wave of the SIGMA study between January 2018 and May 2019.ResultsChildhood interpersonal adversity was associated with increased identity confusion and decreased identity synthesis. Additionally, identity confusion was associated with increased self-reported levels of psychopathology and potentially mediated the association between childhood adversity and psychopathology. ConclusionThis study highlights the importance of promoting healthy identity formation in adolescents with and without exposure to adverse childhood experiences.
An International Study of the Relationship between Teachers' Experience and Readiness to Teach Online
Authors: Scherer Ronny , Siddiq Fazilat , Howard Sarah , Tondeur Jo
Published: May 2022

In the present study, we tested the common assumption that teachers with more experience consider themselves better prepared for online teaching and learning (OTL). Utilizing an international data set of 731 teachers in higher education at the beginning of the COVID-19 pandemic, we performed structural equation and network modeling to quantify the experience-readiness relationship. In contrast to the linearity assumption “the more experienced, the better prepared”, we found robust evidence for a curvilinear relationship. Teachers’ readiness for OTL increased first and then decreased with more experience—this applied especially to the self-efficacy dimension of readiness. Further analyses suggested that the experience-readiness relationship does not only exist at the level of aggregated constructs but also at the level of indicators, that is, specific areas of knowledge, teaching, and support. Hence, describing the experience-readiness relationship requires a measurement perspective that accounts for possible differential functioning of the readiness measures. We argue that both novice and experienced teachers in higher education could benefit from experience-appropriate, pedagogical, and content-related support programs for OTL.
Raspberry Pi and Rubber Ducks: Digital Pedagogy and Computer Anxiety in the LIS Classroom
Authors: Kistler Mattock Lindsay
Published: May 2022

The information professions demand digitally literate practitioners who can navigate the increasingly complex technological environments of libraries and archives. While basic literacy is presumed among graduate students, many students express fear and anxiety when approaching new technologies. These psychological barriers have not been addressed in the digital literacy discourse, yet they must be overcome if LIS educators are tasked with teaching future professionals to critically engage and evaluate the myriad technologies available for library systems and services. This article describes the introduction to computing course at University of Iowa that uses the Raspberry Pi (RPi) computer as a means for teaching critical digital literacy skills in the LIS curriculum. Designed to afford students opportunities to peer into the black box of the computer and build the confidence and knowledge to engage with unfamiliar technologies, the course adopts active learning pedagogy using the RPi. This article discusses the design and development of the course and presents the self-reported data from students regarding their perceived gain in experience and comfort with computing over the course of the term. While further research is required to fully understand the relationship between anxiety and computing, the findings suggest that adopting a critical digital pedagogy that focuses on the process over the end product provides space within the learning environment for students to take risks and develop heuristics for overcoming anxiety and building literacy skills.
Exploring Ways of Knowing: Teaching the Skill of Health Literacy to Refugee and Immigrant Women
Authors: Sullivan Zimmerman Margaret , Rodgers Brianna
Published: May 2022

Refugees and immigrants have adverse health outcomes after arriving in the United States. These negative outcomes tend to be disproportionate to those of the general population, regardless of the person’s health status upon entry to the country. Research has shown that strong health literacy skills can improve health outcomes in this group. This article reports the results of a pilot in which Library and Information Science Master’s students deliver health literacy training to refugee and immigrant women. This training was created in consultation with experts and community partners. The participants were pre- and post-tested with the Short Test of Functional Health Literacy for Adults (STOFHLA) to assess the efficacy of this intervention. Following the completion of the course, the participants were interviewed and asked for comprehensive feedback on the relevance and helpfulness of the program to satisfy their health-related information needs. Their feedback was substantial and will be the basis of a future iteration of this pilot. The pre- and post-test scores of the group showed a statistically significant improvement, providing evidence that the course was effective in raising STOFHLA scores. This article provides insight into providing health literacy instruction for a highly vulnerable group that may be invaluable to library and information science professionals. The purpose of this work is to create a replicable curriculum targeting immigrant and refugee women to be delivered at libraries—and a program in which LIS students can get involved to prepare for dynamic community engagement.
By the Book: A Pedagogy of Authentic Learning Experiences for Emerging Makerspace Information Professionals
Authors: Melo Marijel (Maggie) , March Laura
Published: May 2022

Can LIS curricula dedicated to makerspaces provide an authentic learning experience for future librarians interested in makerspace-adjacent careers? This article presents a case study in which an authentic learning framework is applied to a newly developed LIS graduate-level course on makerspaces. We detail how one class project—entitled “Bibliocircuitry: Old Books, New Ideas”—challenged students to use their newly learned skills to upcycle a hardcover book into a personalized artifact. This article outlines emerging patterns and themes from an analysis of survey responses from 13 of the 15 students in the course. Findings reveal the project readily maps to authentic learning standards, encourages learning, and facilitates reflection (including the negotiation of uncertainty, overcoming debilitating perfectionism, and transformative joy). The study broadens curricular design interventions for LIS educators, highlights the need for deep learning with technologies, and offers an opportunity to narrow the preparation gap between information professionals and the technical and social competencies required in makerspaces. The implications of these findings for the field of LIS pedagogy emphasize the importance of an authentic learning project both to disrupt the absence of LIS maker curricula and to reimagine current one-shot, pressured, makerspace training.
Self-Portraiture in the Information Classroom
Authors: Gorichanaz Tim
Published: May 2022

Arts-based pedagogy is a methodology that integrates artistic practices with other domains to enhance student learning, and it has been shown to engage students and deepen their knowledge acquisition, help them connect theory and practice, inspire positive mood and social learning, and more. Though arts-based pedagogy is not yet widely used in LIS courses, it aligns with skills that information professionals today are asked to develop, such as creativity and design thinking. This short communication offers two arts-based approaches that instructors can use to imbue their classes with creativity in the form of self-portrait drawing. The first is an hour-long reflective drawing activity appropriate for the beginning or end of a course, and the second is a longitudinal activity in which self-portraits are used for taking attendance. These are “small teaching” approaches that can be readily integrated within an existing course without much effort.
An Uneasy, Challenging, Yet Meaningful Experience: A Reflection on a Face-to-Face to Online Synchronous COVID-19 Course Transition
Authors: Phillips Abigail
Published: May 2022

During the 2020 spring semester, as COVID-19 infection rates increased, universities and colleges closed campuses and moved courses online. All of these responses occurred as the Center for Disease Control (CDC), World Health Organization (WHO), and other national and global health organizations attempted to understand this new and deadly illness. Library and Information Science (LIS) schools were, in particular, ready for this unexpected education shift with their long history of online learning and online engagement. This article is both a reflection on and analysis of the teaching experiences of the author during this period of crisis.
The Evolution of Library and Information Science Education Promotion: A Comparative Analysis of LIS Program Websites between 1999 and 2019
Authors: Fraser-Arnott Melissa
Published: May 2022

This study compares library and information studies (LIS) departmental websites from 1999, 2009, and 2019 to explore the evolution of program promotion practices. Websites were analyzed using the 7Ps Marketing Mix model to explore how programs were marketed across this timeframe. Similar promotional messages were used across the years, but a key difference over time was that the 1999 sites promoted the program whereas the 2019 sites promoted people (faculty and students). Three key findings concerning changes in how LIS program websites evolved between 1999 and 2019 to serve program public relations goals were that (1) websites and social media have become key mechanisms for relationship building and promotion; (2) websites have evolved from sharing program details to showcasing faculty and student success stories as the core element of program promotion; and (3) the development of social media and dynamic websites have made these websites more interactive and content rich. An understanding of changes in LIS program websites over time can assist LIS program administrators in developing current and future program promotions activities.

The data in this study indicate that current LIS students take their courses “on the go,” moving easily between a formal learning setting to an informal one, and provide instructors with considerations for the multiple ways in which students may access course content and engage with others in their classes using mobile devices.
Using Constructive Alignment to Support Metaliteracy in International Classrooms
Authors: Schuster Kristen , Stewart Kristine N.
Published: May 2022

This paper discusses strategies for promoting literacy and metaliteracy development in international and multicultural classrooms. Drawing on the first author’s observational research and the second author’s expertise in metaliteracy, we present a case study of international postgraduate students in an interdisciplinary department. The authors synthesize their different areas of work to describe how a fusion of metaliteracy, constructive alignment, and learning oriented assessments (LOA) facilitates student engagement with theories of knowledge organization and extensible markup language (XML) data-encoding standards. Our discussion describes curriculum design and redesign strategies and contextualizes observations about student success. The authors’ observations provide a basis for proposing methods for using metaliteracy to implement constructive alignment and LOA methods for promoting collaborative and truly diverse learning.
“The Ticket You Get Punched”: The Divide between Academic and Public Librarianship and the MLIS
Authors: Freeburg Darin , Vera A. Nick
Published: May 2022

Most professions experience at least some real or perceived divide among practitioners who engage in the work of the profession daily and those who train practitioners. As a result, practitioners question the value of this training. The goal of the current study was to learn more about this divide in Library and Information Science (LIS) and uncover potential solutions. In six focus groups (FGs), practicing academic and public librarians discussed curriculum in light of the requirements of the profession. Findings suggest that practitioners still perceive a divide among themselves and LIS educational institutions. Participants generally viewed the MLIS as little more than “the ticket that you get punched” to get a job. A consistent concern across participants was the irrelevance of skills training, suggesting the need for MLIS programs to engage often with local practitioners to identify workplace trends and required skills. Participants also noted that the communities served by the profession exist as an abstract idea in the MLIS, because students do not interact directly with the people who make up these communities. Findings suggest that the MLIS can reassert its value through a renewed emphasis on core values of the profession, which are not learned on the job. Therefore, while the divide persists, the conversation with practitioners outlined in the current study is itself a means of closing it. This study contributes to the literature on LIS education by highlighting the value of FGs as a method within this literature.
Shape Memory Alloy Actuated Vortex Generators: Alloy Design
Authors: Benafan O. , Gaydosh D.J. , Bigelow G.S. , Noebe R.D. , Calkins F.T. , Nicholson D.E.
Published: May 2022

Aerodynamic devices, such as vortex generators, are often used to reenergize flow and improve aerodynamic performance of aircraft control surfaces. Often the static, non-moving surfaces are designed for specific flight conditions and decrease performance, such as increasing drag and fuel consumption, at other conditions. One example is vortex generators (VGs), small vanes located throughout the aircraft surfaces. VGs are typically not required for the entire flight profile but are essential for conditions such as low speeds during take-off and landing. The static nature of standard VGs stems from the inability to adapt conventional actuators due to mass, complexity, or footprint constraints given their small size and placement on outer surfaces of the aircraft. Shape memory alloys (SMAs) present an opportunity to enable actuation of such devices with a minimal mass and dimension, while still providing high energy densities. Additionally, SMAs can be passively used as sensors if carefully "tuned" to respond to the altitude temperature differential and passively actuate without the need for heaters, active controls, or additional sensors and instrumentation. In this work, the authors report on the development of low temperature SMAs for passively actuating VGs based on temperature changes from ground to cruise altitudes.
Influence of Stress on the Transition Behaviour of NiTi Shape Memory Alloys for Actuator Applications
Authors: Eyer P. , Trauth A. , Weidenmann K. A.
Published: May 2022

Shape memory alloys (SMA) stand out due to the ability that they can be deformed and then return to their initial shape by heating. This process results in a high actuation energy density. All SMA manufacturing methods, regardless of which matrix material is used, result in heat input into the SMA, which could induce a phase transformation and therefore disable the actuator function. In this regard, options to increase the transition temperatures of NiTi alloys above the processing temperatures are fundamental. In this study, the influence of the pre-tension on the transformation temperatures of SMA wires was investigated as a way to prevent phase transformation due to heat impact during the production of SMA-polymer-actuators. Applying a pre-tension of 400 MPa to the NiTi wire, the austenite start temperature could be increased by a factor of 1.9 whereas it could be increased by a factor of 2.2 with a pre-tension of 550 MPa. Therefore, after preloading the wires, a phase transformation should not be induced when the wire contacts the polymer droplets. However, the shift of the phase transformation has to be further investigated.
Development and Mechanical Testing of Low Hysteresis Shape Memory Alloys
Authors: Montagnoli Andre , John Neha , Young Marcus L. , Tad Calkins F. , Nicholson Douglas E.
Published: May 2022

Shape memory alloys (SMAs) have gained attention in recent years as a powerful mechanism for mechanical actuation in space applications. One issue facing this technology is that most commercially available SMAs yield a high amount of energy loss due to their relatively large hysteresis, which can translate into an increase in the overall cost of the mission. Low hysteresis shape memory alloys (LHSMAs), which exhibit a much narrower hysteresis, are needed to minimize this energy loss. Previous studies have shown that elemental additions of Cu, Co, and Pd to the NiTi-based SMA can result in shape memory alloys with a much lower thermal hysteresis, due to better phase compatibility. This present work investigated seven alloy compositions to identify LHSMAs with less than 20 °C hysteresis and develop processing routes for these LHSMAs to determine potential candidates for space actuation applications.

Published: May 2022

A comprehensive shape memory materials database (SMMD) repository is being developed that provides access to a large collection of information on shape memory materials (SMMs) in a single source. The collection of point data and metadata provides insight into actuation properties, structural performance, chemical data, processing records, and similar factors pertinent to shape memory alloys, polymers, and ceramics. The data is organized in a 2D and 3D visualization platform allowing users to gain immediate access to data insights and trends with only a few button clicks. All data points have full traceability to the original source to verify findings and create a link to researchers and scientists within the community. In addition to millions of datapoints already displayed, the web-application also offers access to analysis tools, references to international standards, and resources pertinent to the SMM community.
A New Constitutive Modeling Approach for Shape Memory Alloys
Authors: Landis Chad M. , Kyriakides Stelios , Jiang Dongjie
Published: May 2022

A new thermomechanical constitutive modeling approach for shape memory alloys (SMAs) that undergo a martensite to austenite phase transformation and the associated pseudoelastic and shape memory responses is presented. The novelty of this new formulation is that a single transformation surface is implemented in order to capture the forward and reverse phase transformations, as well as the reorientation and detwinning of the martensite phase. The framework is akin to the usual flow theory plasticity with kinematic hardening, however in addition to the transformation strain there is also a transformation entropy that is directly related to the martensite volume fraction appearing in prior theories. A transformation surface in effective stress and effective temperature space is introduced and an associated flow rule governs the evolution of the transformation strain and entropy. In order to capture the multitude of SMA behaviors, a transformation potential function is introduced in transformation strain and entropy space for the derivation of the back stresses and back temperatures that define the kinematic hardening behavior. It is this potential function that governs all of the important behaviors within the model. After the description of the general theory, specific forms for the transformation surface and the transformation potential are devised and results for the behaviors captured by the model are provided for a range of thermomechanical loadings. The model is then implemented in finite element calculations to investigate the structural response of shape memory alloy tubes, bars, and beams.
Combination of Solid and Porous Nitinol Implants in Surgical Treatment of Extensive Post-Excision Thoracic Defects in Cancer Patients

Published: May 2022

Radical surgical intervention for chest wall tumors is typically accompanied by the lesion of osteochondral structures and the appearance of complex post-resection defects, which result in functional and aesthetic impairment. After extensive resection of the chest wall, it is vitally important that it be simultaneously repaired, including restoring the osteochondral framework and the integrity of the integumentary tissues as well as maintaining the anatomical and physiological volume of the mediastinum and the pleural cavities. Porous and solid Nitinol implants and their successful deployment in surgical treatments have encouraged insights for immediate and delayed osteoplasty in cancer patients. The novel aspect of this work consists in this surgical method of post-excision defect repair is performed using a proprietary approach and customized NiTi-based implants. The results indicate that the suggested surgical approach and tactics using one-step repair are one of the promising techniques even though the case is aggravated with extensive chest wall lesions. The approach can be performed safely and can be recommended as a routine procedure with a high success rate. Combined Nitinol implants seem to be very good reinforcing biomaterials that enabled the reliable repair of thoracic post-excisional defects of various sizes with good functional, clinical, and cosmetic outcomes.

The continuous rolling of Nitinol alloys is a metalworking process with the ability to produce large quantities of sheet with uniform properties for the use in actuation applications in motion systems with cyclic loads. Great advantages of continuous rolling in comparison with other manufacturing methods are the cold work and heat treatment steps and their ability to influence the properties of the product and keep them in a very tight window over the width and the length of the process. Those tightly controlled properties are key-requirements to use the continuous rolled Nitinol material for subsequent automated processes like stamping in progressive dies or deep- drawing. It is also required for efficient reel-to-reel laser or EDM cutting. The primary objective of this work is to evaluate and obtain the properties of Nitinol continuously flat-rolled sheets and optimization of the process parameters by fatigue evaluation.

In this work, a new method of processing shape memory alloys was utilized to understand the effects of disrupting the martensitic long range order and forming amorphous nanodomains with martensitic short range order. Based on the obtained results, strain glass alloy states were analyzed and confirmed using various characterization methods to determine trends and compare two alloys, Ni49.5Ti50.5 and Ni50.8Ti49.2. For Ni49.5Ti50.5 a 33% thickness reduction was required to obtain a cold work-induced strain glass state, while for Ni50.8Ti49.2 a 24% reduction was required.

There is an increasing demand for high quality Nitinol medical devices and implants to accommodate to the rapid growth in the biomedical market. Extensive studies have confirmed the significant impact of micro-cleanliness of Nitinol on fatigue life. Ultra-clean Nitinol material is required for most critical medical applications such as cardiovascular and neurovascular devices for which integrity and durability are critical. This poses challenges for upstream manufacturers to consistently produce ultra-low inclusion Nitinol mill products. This work is a comprehensive to evaluate hot rolled bars and coils of a new commercial scale ultra-clean Nitinol alloy. The robustness of the alloy production process and stability of product properties was confirmed by examining a large number of mill products manufactured in different campaigns. Extensive characterization and multiple approaches of inclusion analysis demonstrated the consistent ultra-high cleanliness of the products.

Nitinol's thermomechanical properties are well studied and understood below the so-called martensite death (MD) temperature, above which martensite cannot be induced by mechanical stress: Even at high stresses Nitinol stays in the austenite phase. This paper presents tensile tests performed well above MD (>150 °C) with Nitinol specimens laser cut from tube. The investigations show that Nitinol drastically changes its mechanical properties in this temperature range: The superelastic plateau shortens and finally vanishes. Furthermore, Nitinol starts becoming more ductile.

Achieving stringent chemistry standards is necessary for additive manufacturing of Nitinol shape memory alloys. This work describes an elevated temperature gas-solid reaction processing technique that can be used to precisely regulate the chemistry and phase transformation behaviors of Nitinol components. The technique, Shape memory alloys via Halide-Activated Pack Equilibration (SHAPE), employs established principles of chemical vapor transport to equilibrate a substrate against reactive pack mixtures designed to regulate the chemical potentials of nickel and titanium in accordance with Gibbs' phase rule as means to precisely control substrate phase and elemental composition. The results suggest that SHAPE may find crosscutting potential especially when paired with additive manufacturing or fusion welding of Nitinol to improve product quality. Notwithstanding future applications, SHAPE is limited by solid-state diffusion that, in turn, limits the practical thickness of suitable components to about 1 mm. Opportunities for continued development have been identified for application to other compositions, and to further refine microstructure control.

Published: May 2022

Although improvements in fatigue performance with increasing Nitinol microstructural purity have been previously characterized, there is limited information on whether corrosion resistance is impacted by reductions in inclusion size and distribution. The objective of this study is to characterize the surface oxide for different Nitinol microstructural purities and determine its influence on corrosion susceptibility. To assess the surface oxide, X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS) were performed on Nitinol heart valve frames with a variety of purities and surface finishes.
