Obstacles of providing exclusive breastfeeding among working mothers using social-ecological theoryBackground: The coverage of exclusive breastfeeding (EBF) in Indonesia was increased to 38% but it was lower than the Millennium Development Goals (MDGs) target (80%). One of the influence factors is to return to work. Society assumed that a mother who stays at home more successful to provide EBF than working mothers. A previous study indicated that some obstacles become early cessation factors among working mothers.Objective: To explore the obstacle of breastfeeding using social-ecological theory.Methods: Qualitative research inquiry based on phenomenology design. Informants were chosen through purposive sampling. Inclusion criteria were working mothers who succeeded provide exclusive breastfeeding, had children age 6-24 months, lived, and formally worked at Manado. Data triangulation was conducted through in-depth interviews with the manager/supervisor/colleague. Data collected using in-depth interviews and observation.Results: A total of twelve informants have interviewed consists of six working mothers and six triangulation informants. The result indicated that lack of confidence was related to providing exclusive breastfeeding. This is caused by family influence, culture, health provider, and lack of awareness from the working place. A support group was the main factors that influence the mother to overcome all obstacles.Conclusions: The main obstacles for working mothers to provide EBF come from interpersonal factors that determined by other factors: intrapersonal, organizational, community. Therefore working mothers need breastfeeding preparation since early pregnancy to decrease breastfeeding obstacles.

Pada estimasi volume insula pancreatica didapatkan titik terhitung 7102 dengan a/p 229,57 µm2yang menghasilkan penghitungan fraksi volume insula sebesar 30,8%. Volume insula pancreatica terhitung sebesar 0,65x109 µm3 (CE 7,6 %).Kesimpulan: Metode yang dilakukan merupakan cara yang mudah dan murah untuk melakukan estimasi volume, namun memiliki keterbatasan karena jarak antar titik tidak dapat disesuaikan dengan mudah.
Measuring Tax Authority Monitoring
Authors: Finley Andrew R. , Stekelberg James 
Published: February 2021

ABSTRACT
Despite growing academic interest in tax authority monitoring, the literature remains lacking a summary measure of realized tax authority monitoring that can be constructed from firms' publicly available financial statement information. The purpose of this study is to develop such a measure. Specifically, we view unrecognized tax benefit (UTB) releases due to settlements with the tax authority to indicate greater tax authority monitoring, and UTB releases due to lapses in the statute of limitations to indicate lesser tax authority monitoring. Among other tests, we validate a new measure of tax authority monitoring utilizing data from UTB releases by documenting its positive associations with predicted determinants of tax authority monitoring and by showing that it varies across time in expected ways. We believe our measure should be useful to future researchers studying tax authority monitoring in a variety of settings.
The Effects of Goal Publicity and Incentives on Self-Set Performance Goals
Authors: Chen Clara Xiaoling , Yin Huaxiang , Zhang Yue May 
Published: February 2021

ABSTRACT
Many companies encourage employees to set their own performance goals and do not attach formal incentives to the achievement of these goals. In this environment, some organizations make employees' self-set performance goals public while other organizations do not. We predict that, due to strategic concerns induced by goal publicity and competition, making goals public will be more likely to lead employees to lowball their goals when they work under tournament incentives than under piece-rate incentives. Consistent with this prediction, our experimental results reveal that making self-set performance goals public decreases goal level under tournament incentives but has no significant effect on goal level under piece-rate incentives. Results of our study suggest that the practice of making self-set goals public is potentially more compatible with organizations with a collaborative culture than those with a competitive culture.

Measuring Multidimensional Investment Opportunity Sets with 10-K Text
Authors: Basu Sudipta , Ma Xinjie , Briscoe-Tran Hoa 
Published: February 2021

ABSTRACT
We show that firms' investment opportunity sets (IOS) are multidimensional. Analyzing Form 10-K texts, we identify 445 unique keywords that predict firms' future investments during 1995–2009 and combine them into 43 underlying factors. Industry-specific factors include Bio-Pharma, Banking, Information Technology, Oil and Gas, and Retail Stores, while more general factors include Equity Intensity, Debt Intensity, Lease, Going Concern, and Acquisition. These factors form our multidimensional measures of IOS. They outperform Tobin's Q and/or industry fixed effects, in predicting future out-of-sample (2010–2015) investments and related corporate policies, and even inform incrementally over lagged dependent variables. We trace the factors' improved predictive power to their multidimensional nature, which captures IOS-related variation within and between industries, and stability in IOS that allows 10-K texts to be more informative.

Results of experimental studies of changes in the level and heating of the main condensate in mixing-type LPH
Authors: Sukhorukova E. A. , Trifonov N. N. , Kolpakov S. P. 
Published: February 2021

In the thermal circuits of domestic steam turbines, mixing-type low-pressure heaters (LPH) with free-flow jet water distribution and counter-flow of water and steam are widely used. The choice of the counterflow variant of the media movement ensures the most efficient heat transfer. However, the technical problem of ensuring reliable operation of LPH in the entire range of design loads of TPP and NPP power units is still relevant.During the commissioning and operation of mixing-type LPH in 800÷1200 MW turbines of TPP and NPP, the presence of metal knocks in the zone of the check valve, hydraulic shocks in the heating section were revealed. A priori, these phenomena indicated design flaws in LPH or manufacturing defects in their production. Research carried out by NPO CKTI specialists showed that periodic hydraulic shocks in the heating section and metal knocks occur as a result of uneven distribution around the circumference of the main condensate and steam supply. This leads to a breakdown of the check valve and the destruction of perforated plates and off-design heating of water in the volume of the annular LPH water chamber. To clarify the causes of the damage, develop recommendations for the reconstruction of the apparatus and further account for the design, two series of experimental studies were carried out on mixing-type heaters of 800 MW turbine units PNSV-2000-1 and PNSV-2000-2 manufactured at PJSC Krasny Kotelshchik. The purpose of the experimental studies was to determine the change in the water level in the water chamber and the heating of the main condensate in the elements of the heating compartment during normal operation of the power unit at loads of 400÷850 MW. Based on the results of the research, the method for calculating the mixing-type LPH has been refined, taking into account the revealed non-uniformity of water heating in the water chamber, recommendations for their reconstruction have been developed and implemented.
Motivating Students to Engage in Preparation for Flipped Classrooms by Using Embedded Quizzes in Pre-class Videos
Authors: Jones Emily P. , Wahlquist Amy E. , Hortman Melissa , Wisniewski Christopher S. 
Published: February 2021

Background: The success of flipped classrooms is dependent upon students’ preparation prior to class, the lack of which is the most common challenge associated with this teaching methodology. To mitigate this limitation, it is important to develop and assess methods of engaging learners during pre-class activities.
Objective: To determine if quiz delivery method (embedded throughout versus after pre-class videos) affects students’ knowledge retention, grades, and video viewing behavior.
Methods: Participating students were randomized to take quizzes, either during pre-class videos via Panopto™ (EQV) or after pre-class videos in the traditional manner via Moodle™ (TMM). Outcomes assessed included students’ knowledge retention, scores on pre- and post-class quizzes, and pre-class video viewing behavior (total views and minutes viewed per student) during a three-week period. Having experienced both quizzing modalities during the semester, the perceptions from students in the EQV group were surveyed.
Results: Baseline assessment results of both groups (n = 27 per group) were comparable with a median score of 33% (IQR: 17, 50) in both groups. Performance was also similar on knowledge retention [TMM: 67% (50, 83) vs. EQV: 83% (50, 83)], pre-class quiz scores [TMM: 90% (87, 97) vs. EQV: 93% (90, 95)], and post-class quiz scores [TMM: 93% (80, 100) vs. EQV: 87% (80, 100)], while students in the EQV group had more total views [10 (8, 12)] vs. [5 (2, 11)] and minutes viewed [71 (36, 108) vs. 35 (15, 81)]. Results from the perception survey administered to students in the EQV group (74.1% response rate) indicated a preference for embedded quizzes overall (58%) and for class preparation (75%) when compared with post-video quizzes.
Conclusion: Students’ knowledge retention and performance were similar in both EQV and TMM groups, though students in the EQV group were more engaged with videos and most of them preferred this quiz delivery. Using embedded quizzes for formative rather than summative assessment might be an appropriate mechanism to encourage students’ viewing of pre-class videos and their preparation for flipped classes.
Covid Media Misguidance: A Case Report Highlighting the Influence of Media on Patient Medication Decision Making
Authors: Anderson Shaylee , Windscheffel Joe , Gunning Karen 
Published: February 2021

Purpose: This case report details the influence of media on patients and the responsibility of health care providers to educate their patients on proper use of medications, and to be aware of potential misadventures based on messages in popular media.
Summary: The sudden rise of the COVID19 pandemic has led to media outlets reporting science without necessary peer review and has resulted in preliminary data presented as factual evidence. It is difficult for patients without an extensive medical background in science to fully understand the uncertainty of information shared in popular media. This was demonstrated when preliminary data showed potential promise of hydroxychloroquine for the treatment/prevention of COVID19. This led to patients requesting hydroxychloroquine prescriptions from their providers, as well as stockpiling medication, which led to a shortage. In addition, patients began taking chloroquine containing substances not intended for human consumption. Popular media created a belief in the general public that all antimalarial drugs may work to prevent COVID19. This case report presents an elderly patient that presented to clinic with shortness of breath and lightheadedness. Upon interviewing the patient, it was discovered that he had been taking an old supply of atovaquone and proguanil hydrochloride. Physical exam, and laboratory examination were evaluated to rule out any other etiology with all tests and exams being unremarkable. Two weeks after stopping atovaquone and proguanil hydrochloride, the patient’s symptoms completely resolved.
Conclusion: The media provides a significant portion of the information that patients receive regarding rapidly changing treatment information in a pandemic. It is crucial for health care providers to know what information patients are exposed to, and to educate patients with evidence-based information. Pharmacists are the most accessible health care providers and have a key role in medication review and management. Educating patients on evidence-based use of medications may help avoid harm caused by misinformation from unreliable media sources.

Objetivo: Realizar uma revisão integrativa de artigos voltados para os casos de hepatite B na Amazônia. Métodos: Este estudo consiste em uma revisão da literatura, realizada entre 2013 e 2019, na qual realizou-se consulta a artigos científicos em língua inglesa, portuguesa e espanhola, selecionados através de busca no banco de dados do Scielo e da Bireme, a partir das fontes Medline e Lilacs. Resultados: Foram selecionados 26 artigos e todos atrelam às altas taxas de prevalência da infecção pelo vírus da hepatite B na Amazônia. Dentre esses, 5 artigos abordam sobre a prevalência da infecção nos estados do Pará, Acre, Rondônia e Amazonas, 7 artigos focam em aspectos epidemiológicos e clínicos, 4 se pautam no diagnóstico, 5 sobre os diferentes tratamentos e 5 abordam sobre medidas profiláticas. Considerações finais: Conclui-se que a Hepatite B é um grave problema de saúde no Brasil, sobretudo na região amazônica, por conta de imunização ausente ou incompleta, embora as vacinas protetoras contra a hepatite B tenham sido introduzidas. Por isso, há necessidade de reavaliação dos programas já instituídos e implementação de novas políticas a fim de reduzir a hepatite B na população.
