PERANAN VARIASI PERFORATED PLATE BURNER PADA PEMBAKARAN PREMIXED MINYAK KELAPA MURNI TERHADAP KARAKTERISTIK NYALA API
Authors: Aristyanto Agil
Published: February 2021

Terdapat berbagai macam metode untuk menentukan dan mengukur besarnya kecepatan pembakaran laminer salah satunya menggunakan metode bunsen burner dengan penambahan perforated plate untuk mendapatkan pembakaran api yang efektif, singkat dan nyala api lebih stabil. Utamanya untuk merespon regulasi emisi gas hasil pembakaran. Selain masalah emisi gas, masalah keterbatasan bahan bakar fosil juga menjadi masalah yang penting . Kebutuhan bahan bakar minyak akan bertambah seiring meningkatnya pembangunan. Hingga saat ini banyak dikembangkan bahan bakar alternative dari minyak nabati yang mengandung gliserol dan asam lemak (Wirawan, Wardana, Soenoko, & Wahyudi, 2014). Penelitian ini menggunakan uap minyak kelapa yang dicampur dengan udara pada perforated plate burner untuk menghasilkan nyala api premixed. Variasi AFR yang digunakan adalah 6,7; 9,6; 11,9; 13,7; 15,4; 16,8; 18,9 dan 19,4 untuk menghasilkan equivalence ratio yang bervariasi. Untuk variasi perforated plate adalah 7, 9 dan 11. Hasil dari penelitian ini adalah banyaknya jumlah perforated plate mempengaruhi pada bentuk nyala api pada pembakaran premixed lebih transparan, jernih dan nyala api nampak seperti kelopak bunga. Pada campuran miskin (equivalence ratio < 1) dengan pengaruh banyaknya jumlah perforated plate kecepatan pembakaran api lebih tinggi, sehingga temperatur yang dihasilkan jadi meningkat daripada jumlah perforated plate sedikit, namun pada tinggi nyala api semakin rendah dengan jumlah perforated plate lebih banyak.

Desenvolvimento autônomo e crise estrutural do capitalismo no século XXI
Authors: Machado Lima Junior Humberto
Published: February 2021

Este artigo aborda como os princípios constitutivos do conceito de desenvolvimento autônomo de Hélio Jaguaribe oferecem respostas à crise estrutural do capitalismo global no século XXI. Essa crise émarcada pelo empoderamento do capital sobre o trabalho que repercute na privatização do capital e na estagnação da demanda. Diante desse processo político-econômico global,gerado pela austeridade neoliberal, o desenvolvimento autônomo aponta para políticas distributivas e de transformação produtiva das economias periféricas visando o reequilíbrio da divisão internacional do trabalho. Tal perspectiva aproxima as teses de Jaguaribe das propostas neokeynesianas para conter o avanço do neofascismo global no início do século XXI.
Augustinian Recollect Contributions to the Church History and Cultural Patrimony of Palawan
Authors: Romanillos Prof. Emmanuel Luis
Published: February 2021

The paper explores the historical presence and contributions of Agustinian Recollects in Palawan, particularly to the Church history and cultural patrimony of the island. Father Larry Garces, then provincial secretary and ex-officio provincial archivist, wrote: “The first Recollects accordingly arrived through the smaller island of Cuyo even as early as 1622. And from then on, a great tradition of Recollection ensured. Among the illustrious Recollects who came to the island of Palawan was Saint Ezekiel Moreno. They were builders and organizers of churches and cities. They were good preachers and evangelizers bringing the Good News to the farthest boundaries, and the innermost territories. We are indeed very fortunate that the last Recollects of the 80’s left the island and its vast agricultural and coastal territories with impressive memories of hard work, religiosity and real care and concern for the flock. But that was the past—and yes, indeed, the glorious past.”

Authors: Lacdo-o Batchiba R.
Published: February 2021

This paper compared on-campus and off-campus practice teaching experience of 49 baccalaureate students in Elementary and Secondary Education of Silliman University College of Education. A self-administered questionnaire, the revised Student Teacher Assessment on the Silliman University Student Teaching Program, was the main data gathering instrument used. The Wilcoxon Matched-Pairs Rank Test showed that there was no significant difference in the student teachers’ ratings of their on-campus and off-campus experiences.  The same findings were noted on the challenges they have encountered and the recommendations they have posited, namely: classroom management and mentors’ support and relationship.  Further, the findings revealed that classroom management and mentors’ support and relationship were their top two challenges.  The student teachers strongly recommended that support for student teaching be improved especially in terms of mentors’ support and scheduling.  In addition, they strongly recommended that they are pre-observed by their supervisors before their final student teaching demonstration.

Authors: Cordova Maryver A. , Sia Adelyn D.
Published: February 2021

This quantitative study determined the associations among the demographic variables, the extent of coping strategies, and the degree of resiliency of the informal caregivers. By using standardized instruments as well as profile sheets and checklists, 103 informal caregivers who are full-time provincial government employees provided data for this study. By using descriptive statistics, Pearson r, and eta correlation in analyzing the results, findings showed no significant relationship among the demographic variables and the extent of coping strategies and the degree of resiliency. However, relationships revealed between age and problem-focused coping strategy and between resiliency and emotion-focused coping strategy. Furthermore, resiliency could be attributed to both internal and external sources and associated with a coping strategy. It could also predict the extent of coping used by informal caregivers. Moreover, caregiving had both positive and negative effects on their health and well-being.

Authors: Alcantara Rogen Ferdinand E.
Published: February 2021

This study aims to determine the real-life context on quality of life, spirituality, and resiliency among natural disaster adult survivors in Negros Oriental and Bohol.  The case study method was utilized to investigate the real-life experiences of seven (7) adult survivors, ages 20 and older, who joined in the Silliman University Continuing Calamity Response Program.  The narratives revealed a commonality of opinions on their quality of life. General sentiment on the available resources may be present but was inadequate. However, despite their ominous view on the quality of life, the majority of the participants chose to move on. Moreover, most participants indicate experiencing spiritual struggles, but these struggles sustained them. Momentarily, the love and support from their family and the community have allowed them to strive and make life adjustments. With this, balanced and holistic recovery programs should be implemented to obtain optimal well-being, spiritual empowerment, and positive resiliency.
Nutrition Security through Sustainable Home Garden Food Production Initiatives
Authors: Honculada-Genove Jin
Published: February 2021

Food security is achieved through food availability, economic and physical access, proper food utilization, and food stability. Safeguarding the access to sufficient food is more a problem than availability for the most malnourished group as food insecure households favor quantity over quality to avoid hunger.  The Nutrition and Dietetics Department of Silliman University, in partnership with the local government units of San Jose and Amlan in Negros Oriental, launched the Nutrition and Food Security Training Program to reduce the problem of malnutrition.  One of the components of the program is sustainable home garden food production, which emphasized the role of home gardening to improve access to food quality, thereby addressing nutrition security.  This qualitative study seeks to describe the views of the participants on home vegetable gardening to address food and nutrition security.  A total of 20 participants were invited to participate voluntarily in this qualitative study.  A focus group discussion was used as a qualitative tool. As a result, participants realized that having a home garden can improve nutrient consumption, provide economic benefits, and address food security of the household.  Food security was tenable within their homes through concerted efforts, patience, and love.  Barangay policymakers were encouraged to formulate legislation and include in their budget the promotion of home gardens to improve the nutritional status of their constituencies.
Rizal, The Social Portraitist
Authors: Albela Emmanuel Jeric A. , Hila Antonio C.
Published: February 2021

This paper attempts to direct on how to understand the two famous novels of Rizal – Noli Me Tangere and El Filibusterismo – within the context of Rizal's intent to expose the social ills of his time. With the use of Charles Derbyshire's translations of The Social Cancer and The Reign of Greed, the researchers explain and show the essential details of the novels and how they reflect historical, social realities as exposed in literary terms – using allegory as synthesis. It includes a re-assessment of the characters in both novels, the key places in the story, conflicts, and how these conflicts are resolved towards the end. The study conveys how Rizal expressed his reflections on and critique of the Philippine society through character and institutional symbolisms. Using historical hermeneutics as a method of the study, the researcher will keep an eye on the available sources and collections of literature, thereby putting the novels in their proper contexts, which properly define Rizal as a novelist and a social critic.

Published: February 2021

Property taxation is a component of land governance policies, processes, and institutions that relies on a land administration system, efficient property market, and secure legal rights. This study assessed the fiscal implication of the Comprehensive Agrarian Reform Program (CARP) in the real property tax (RPT) collection when municipalities are grouped by income classification, size of the area, and land classification. This descriptive-comparative and correlational research used secondary data and a checklist administered to 19 treasurers of a first-class province. Using descriptive and inferential analyses, the study yielded "very great" negative fiscal implications. No significant differences were found when municipalities were grouped as to income and size but a significant difference when areas were identified by classification.  There is a significant relationship between the fiscal implication and the size of the area covered. The respondents encountered challenges. The study recommends revenue generation strategies, legislative support, and livelihood for agrarian beneficiaries.

Authors: Bellinger Phillip M. , Newans Timothy , Whalen Mitchell , Minahan Clare
Published: February 2021

Effective time-motion analysis can provide information directly applicable to the design of physical conditioning and testing programmes. The aim of the present study was to determine the external output of female beach volleyball players during tournament match-play and to assess the effect of competition level, margin of score differential and alterations of external output within matches. The external output profile of ten adult level (age 27 ± 3 y) and ten under 23 (‘U23’; age 19 ± 2 y) female beach volleyball players were determined using GPS technology (10 Hz) during 60 matches (n = 50 first and second sets and 20 third sets files) played during their respective Australian Beach Volleyball Championship tournaments. Comparisons between groups and the influence of contextual factors on the external output within matches were analysed using linear mixed models. Adult beach volleyball players covered a greater relative distance (i.e., m·min-1) in speed zone 2 (1.0-1.99 m·s-1; 42.0% of total relative distance) and zone 3 (≥2.0 m·s-1; 10.9% of total relative distance) compared to U23 players. Relative distance, mean acceleration/deceleration and the relative distance covered in acceleration zone 2 and deceleration zone 2 and 3 was greater in set 1 compared to set 2. Sets that were decided by smaller score margins (<6-point score differential) were comprised of a greater relative distance, peak speed, greater mean acceleration and deceleration output and a greater relative distance in speed zone 1 and 3 compared to sets decided by larger score margins (>5-point score differential). The findings from this study suggest that there are contextual factors that influence the speed and acceleration/deceleration profile of female beach volleyball players such as tournament level, score margin and set-to-set variations that may have implications for the physiological and mechanical requirements of female players preparing for competition.

A Study on the Father Image in Chinese Film and Television
Authors: Xu Fangyi
Published: February 2021

The father image in Chinese film and TV shows is often absent or lacks power. This is a new phenomenon presented by fathers in social relations, family relations and self-identity and reflects the implicit identity anxiety behind the father image in the new pattern of middle-class families. The father image in film and TV shows is no longer a symbol of power and authority of the traditional patriarchy but a deconstruction from the loss of discourse to disintegration, not only reflecting the loss of discourse of individuals’ rights but also presenting a certain metaphor of the era. Fathers recovering from their image collapse requires a new sublimation image so that their power representation and self-worth can be renewed.

The purpose of this study is to research and analyze the second-hand platforms in China and Korea. Todays, second-hand trading has evolved and more and more consumers are using it. In the past, most of the users of the second-hand trading market were low-income households, and the current users of the used trading market are the MZ generation. In this reason, feeling the necessity of researching the second-hand trading platform, I analyze it from data of China and Korea. To achieve the purpose of this study, I collect and analyze two big platform of each country “Xianyu” from China and “Secondhand Market” from Korea. We can see how differences in economies, societies and cultures between China and Korea affect second-hand trading platforms. The study compared the trend of second-hand clothing consumption, the major channels of second-hand clothing consumption, the key categories of second-hand clothing consumption, the leading brands of second-hand clothing consumption, the motivations and obstacles of second-hand clothing consumption. I hope this study to develop the second-hand trading platforms around the world.
The Influences of COVID-19 on Korean Fashion Consumption
Authors: Han Jisoo
Published: February 2021

The outbreak of corona-virus infections has not only adversely affected human health, but also disrupted all trade and economic activities. There are also similar problems with production stoppages due to global isolation and self-awareness isolation. To maintain a competitive edge, an entity should anticipate consumer behavior during this global crisis. In particular, the survey of online purchasing behavior of South Korean consumers is highly relevant during the COVID-19 pandemic. This study investigates how COVID-19 affects South Korean consumers by dividing them into consumption patterns, behaviors, perceived values, and purchase intentions. Furthermore, we investigate the relationship between entertainment and pleasure and normative motivation, and between the purchase intentions of South Korean consumers.

The expected results of this study may help marketers and companies in analyzing the pattern, behavior, perceived values, and intention of purchasing South Korean consumers who have changed to COVID-19. Besides, we provide e-commerce companies with recommendations on how to address consumers' purchasing motivations and strategically utilize them in South Korea.

LEGAL LOOPHOLE IN CRIMINAL LAW
QUALIFICATIONS FOR THE SEIZURE OF VIRTUAL
ITEMS IN ONLINE COMPUTER GAMES
Authors: Budzińsk Jan
Published: February 2021

The main purpose of the article is to show the existence of a certain legal loophole in terms of criminal law qualifications for the broadly understood taking of virtual objects. The author bases this publication on two specific factual states. The analysis of all potentially applicable criminal law grounds leads to the conclusion that there is no adequate legal qualification for these situations. Thus, the conclusions unequivocally confirm the main thesis of the publication, described at the beginning. At the very end, the de lege ferenda postulates are formulated, the message of which is to shape the regulations in such a way that the legal loophole disappears.
THE SOCIAL AND MORAL ATTITUDES OF
CONVICTS AND THEIR PROACTIVITY USED
AGAINST THE LIMITATIONS OF THE PRISON
ENVIRONMENT
Authors: Kwiatkowski Bartosz
Published: February 2021

Th e concept of moral norms is an interdisciplinary issue, defi ned by
diff erent fi elds of science. Attitudes towards the preferred moral norms are
noticeably less frequent in both theoretical and empirical studies, although
in the present study an attempt has been made to establish the relationships
between the personal attitude of convicted persons towards fi ve independent
moral norms and their proactive personality traits.
Th e study involved 100 fi rst-time convicts and 100 recidivists, who
were asked to respond to the statements made in Th e questionnaire on
attitudes towards moral norms and Th e scale of proactivity in penitentiary
isolation. Th e convicts were serving prison sentences in two diff erent
penitentiary units in Poland. Th e results of the research showed that
those convicted for the fi rst time who approved of attitudes towards vindictiveness,
helping others and incitement to evil had a greater propensity
for proactive behaviour. In addition, the group of recidivists showed no
correlation between the declared attitudes to moral norms and their level
of proactivity, but showed that they displayed more positive attitudes
towards helping other people and vindictiveness, in comparison to the
population of fi rst-time convicts. Th e results form an additional source of knowledge about the proactivity
of convicts, which can be skilfully used, and therefore the research
carried out is particularly important for penitentiary practitioners who
carry out various rehabilitation activities, as well as specialists in executive
criminal law.

Authors: Basiaga-Pasternak Joanna , Duda Henryk , Wojtowicz Agnieszka
Published: February 2021

Introduction. Psychological diagnostics in competitive sport is very useful in the selection process. Therefore, proper diagnostic methods are used to be predictive for both teachers and trainers. Aim of research. The aim of the study was to establish the best method for diagnosing football players’ level of intelligence. Materials and methods. Raven’s Progressive Matrices - APIS-P(R), football tests were used. All of the 177 participants (males) practised football. Results. In research, it has been shown that intelligence tests examining crystallised intelligence are not useful in the aspect of training, but may be a clue in the teaching process for teachers. The results of liquid intelligence tests (Raven’s Progressive Matrices) indicate positive correlations with the level of tactical and technical knowledge, as well as efficiency of the tested footballers. Conclusions. In the diagnosis of team sports players, it is useful to test liquid intelligence.
Dosage strategies for delaying resistance emergence in heterogeneous tumors
Authors: Vakil Vahideh , Trappe Wade
Published: February 2021

Drug resistance in cancer treatments is a frequent problem that, when it arises, leads to failure in therapeutic efforts. Tumor heterogeneity is the primary reason for resistance emergence and a precise treatment design that takes heterogeneity into account is required to postpone the rise of resistant subpopulations in the tumor environment. In this paper, we present a mathematical framework involving clonal evolution modeling of drug‐sensitive and drug‐resistant clones. Using our framework, we examine delaying the rise of resistance in heterogeneous tumors during control phase of therapy in a containment treatment approach. We apply pharmacokinetic/pharmacodynamic (PKPD) modeling and show that dosage strategies can be designed to control the resistant subpopulation. Our results show that the drug dosage and schedule determine the relative dynamics of sensitive and resistant clones. We present an optimal control problem that finds the dosing strategy that maximizes the delay in resistance emergence for a given period of containment treatment.
Spaced mathematics practice improves test scores and reduces overconfidence
Authors: Emeny William G. , Hartwig Marissa K. , Rohrer Doug
Published: February 2021

The practice assignments in a mathematics textbook or course can be arranged so that most of the problems relating to any particular concept are massed together in a single assignment, or these related problems can be distributed across many assignments–a format known as spaced practice. Here we report the results of two classroom experiments that assessed the effects of mathematics spacing on both test scores and students' predictions of their test scores. In each experiment, students in Year 7 (11–12 years of age) either massed their practice into a single session or divided their practice across three sessions spaced 1 week apart, followed 1 month later by a test. In both experiments, spaced practice produced higher test scores than did massed practice, and test score predictions were relatively accurate after spaced practice yet grossly overconfident after massed practice.

Physicians were selected by theoretical sampling from urban, tertiary care pediatric hospitals across the United States until theoretical data saturation was achieved. The study applied a constructivist grounded theory approach to data collection and analysis. Manual line‐by‐line coding of interview transcripts was used initially, then grouped into categories with constant comparative analysis to generate the final coding scheme organized by themes and subthemes. Finally, memo‐writing and iterative analysis meetings explored relationships between themes and identified an interpretive model.

Results

Theoretical saturation was achieved after 10 of the initial 12 interviews. Emerging from the data were six themes that describe the concept of intubation sharing: (1) Videolaryngoscopy encompasses multiple modalities that all provide a shared view and ability to record; (2) Airway experts and systems help realize the full potential of videolaryngoscopy; (3) Videolaryngoscopy can be a clinical, educational, quality assurance and research tool; (4) Some skills required for videolaryngoscopy are unique, while others overlap with direct laryngoscopy; (5) Videolaryngoscopy allows a coaching laryngoscopist to provide real‐time guidance to the primary laryngoscopist from a shared view; (6) Videolaryngoscopy provides an opportunity for post‐intubation coaching and feedback and shared learning from a single experience for the provider community.

Conclusions

Through this multicenter qualitative interview study, we derived the concept of intubation sharing through videolaryngoscopy for real‐time and remote coaching, for both the primary laryngoscopist and the community of emergency medicine providers who intubate.

Herein, a remarkable conjugated bis‐guanidinate (CBG) supported zinc hydride, [{LZnH}2; L={(ArHN)(ArN)−C=N−C=(NAr)(NHAr); Ar=2,6‐Et2‐C6H3}] (I) catalyzed partial reduction of heteroallenes via hydroboration is reported. A large number of aryl and alkyl isocyanates, including electron‐donating and withdrawing groups, undergo reduction to obtain selectively N‐boryl formamide, bis(boryl) hemiaminal and N‐boryl methyl amine products. The compoundIeffectively catalyzes the chemoselective reduction of various isocyanates, in which the construction of the amide bond occurs. Isocyanates undergo a deoxygenation hydroboration reaction, in which the C=O bond cleaves, leading to N‐boryl methyl amines. Several functionalities such as nitro, cyano, halide, and alkene groups are well‐tolerated. Furthermore, a series of kinetic, control experiments and structurally characterized intermediates suggest that the zinc hydride species are responsible for all reduction steps and breaking the C=O bond.
Syntheses and Characterizations of the Mixed Noble‐Gas Compounds, [FKrIIFXeIIF][AsF6]⋅0.5 KrIIF2⋅2 HF, ([KrII2F3][AsF6])2⋅XeIVF4, and XeIVF4⋅KrIIF2

Reaction of [XeF][AsF6] with excess KrF2at −78 °C in anhydrous HF (aHF) solvent has yielded the first mixed KrII/XeIInoble‐gas compound, [FKrFXeF][AsF6] ⋅0.5 KrF2⋅2 HF, a salt of the [FKrFXeF]+cation. The potent oxidative fluorinating properties of KrIIfluoride species resulted in oxidation of XeIIto XeIVin aHF at −60 °C to form the mixed KrII/XeIVcocrystals, ([Kr2F3][AsF6])2⋅XeF4and XeF4⋅KrF2. Further decomposition at 22 °C resulted in oxidation of XeIVto XeVIto give the recently reported KrII/XeVIcomplexes, [F5Xe(FKrF)n][AsF6] (n=1, 2), [F5Xe][AsF6], and a new KrII/XeVIcomplex, [(F5Xe)2(μ‐FKrF)(AsF6)2], which was characterized by low‐temperature (LT) Raman spectroscopy. The [FKrFXeF][AsF6]⋅0.5 KrF2⋅2 HF, ([Kr2F3][AsF6])2⋅XeF4 , and XeF4⋅KrF2compounds were characterized by LT Raman spectroscopy and single‐crystal X‐ray diffraction. Quantum‐chemical calculations were used to assess the bonding in [FKrFXeF]+, [Kr2F3]+, and [Xe2F3]+and to aid in their vibrational assignments.

In continuous pharmaceutical manufacturing, consisting of a perfused batch fermentation and integrated continuous downstream processing, the continuous capture is the linking unit operation. For the development of this unit operation, scale‐down models (SDMs) are crucial, whereas discrete, noncontinuous SDMs are preferred over continuous SDM due to their simplistic nature, reduced material consumption, and shorter operation time. The results presented in this study show the suitability of a discrete SDM approach, compared to a continuous SDM for a continuous protein A purification step.

Background

There are several ways to determine psychological resilience. However, the correlation between each measurement is not clear. We explored associations of baseline relative “resilience” and risk with later self‐reported trait resilience and other biological/mental health indices.

Methods

We utilized baseline and follow‐up survey data from 500 participants aged 30–64 in the community cohort. Baseline “relative” resilience was defined by: (a) negative life events (NLEs) in the six months before baseline and (b) depressive symptoms at baseline, yielding four groups of individuals: i) “Unexposed and well,” “Vulnerable (depression),” “Reactive (depression),” and “Resilient.” “Trait” resilience at follow‐up was self‐reported using the Connor‐Davidson Resilience Scale (CD‐RISC). Associations between relative resilience at baseline, CD‐RISC, and heart rate variability (HRV) indices at follow‐up were assessed with generalized linear regression models after adjustments. Associations between baseline resilience and subsequent loneliness/depression indices were also evaluated.

Results

Overall trait resilience and its subfactors at follow‐up showed strong negative associations with “Reactive” at baseline (adj‐β for total CD‐RISC score: −11.204 (men), −9.472 (women)). However, resilience at baseline was not associated with later HRV, which was compared with the significant positive association observed between CD‐RISC and HRV at the same follow‐up time point. The “Reactive” exhibited significantly increased depressive symptoms at follow‐up. The overall distribution pattern of CD‐RISC subfactors differed by baseline resilience status by sex.

Conclusions

The “relative” resilience based on the absence of depression despite prior adversity seems to be highly related with trait resilience at follow‐up but not with HRV. The sub‐factor pattern of CD‐RISC was different by sex.

Iron sulfide (FeS) anodes are plagued by severe irreversibility and volume changes that limit cycle performances. Here, a synergistically coupled hybrid composite, nanoengineered iron sulfide/S‐doped graphene aerogel, was developed as high‐capacity anode material for Li/Na‐ion half/full batteries. The rational coupling of in situ generated FeS nanocrystals and the S‐doped rGO aerogel matrix boosted the electronic conductivity, Li+/Na+ diffusion kinetics, and accommodated the volume changes in FeS. This anode system exhibited excellent long‐term cyclability retaining high reversible capacities of 422 (1100 cycles) and 382 mAh g−1 (1600 cycles), respectively, for Li+ and Na+ storage at 5 A g−1. Full batteries designed with this anode system exhibited 435 (FeS/srGOA||LiCoO2) and 455 mAh g−1 (FeS/srGOA||Na0.64Co0.1Mn0.9O2). The proposed low‐cost anode system is competent with the current Li‐ion battery technology and extends its utility for Na+ storage.

Anxiety and eating disorders (EDs) often co‐occur, prompting calls to explore anxiety‐related maintenance processes in ED samples. Safety behaviors, which function to prevent a feared outcome from occurring or to reduce anxiety associated with a feared stimulus, are observed across anxiety disorders and, along with overt avoidance behaviors, are an important target in treatment. Data suggest that individuals with EDs also engage in safety behaviors. However, no existing assessments provide a comprehensive measure of eating‐disorder‐specific overt avoidance and safety behaviors. The goal of this Stage 1 Registered Report is to develop a comprehensive self‐report measure of ED‐specific safety behaviors. In Study 1, we will recruit 50 women with EDs to complete the scale and provide feedback on the response scale. Feedback from these participants will be used to refine the measure. In Study 2, we will evaluate the psychometric properties of the measure in a large sample of women with EDs (n dependent on the size of measurement) and a community sample without current or a history of ED symptoms. We will explore the measure factor structure, known‐groups validity by comparing scores from women with EDs to healthy controls, internal consistency, and convergent and divergent validity with other psychological instruments.
