A Novel, Combined Student and Preceptor Professional Development Session for Optimizing Feedback: Protocol for a Multimethod, Multisite, and Multiyear Intervention (Preprint)
Authors: Button Brenton , Cook Clare , Goertzen James , Cameron Erin
Published: June 2022

BACKGROUND

Providing feedback to medical learners is a critical educational activity. Despite the recognition of its importance, most research has focused on training preceptors to give feedback, which neglects the role of learners in receiving feedback. Delivering a combined professional development session for both preceptors and students may facilitate more effective feedback communication and improve both the quality and quantity of feedback.

OBJECTIVE

The objective of our research project is to examine the impact of a relational feedback intervention on both preceptors and students during a longitudinal integrated clerkship.

METHODS

Students and preceptors will attend a 2.5-hour combined professional development session, wherein they will be provided with educational tools for giving and receiving feedback within a coaching relationship and practice feedback giving and receiving skills together. Before the combined professional development session, students will be asked to participate in a 1-hour preparation session that will provide an orientation on their role in receiving feedback and their participation in the combined professional development session. Students and preceptors will be asked to complete a precombined professional development session survey and an immediate postcombined professional development session survey. Preceptors will be asked to complete a follow-up assessment survey, and students will be asked to participate in a follow-up, student-only focus group. Anonymized clinical faculty teaching evaluations and longitudinal integrated clerkship program evaluations will also be used to assess the impact of the intervention.

RESULTS

As of March 1, 2022, a total of 66 preceptors and 29 students have completed the baseline and follow-up measures. Data collection is expected to conclude in December 2023.

CONCLUSIONS

Our study is designed to contribute to the literature on the feedback process between preceptors and students within a clinical setting. Including both the preceptors and the students in the same session will improve on the work that has already been conducted in this area, as the students and preceptors can further develop their relationships and coconstruct feedback conversations. We will use social learning theory to interpret the results of our study, which will help us explain the results and potentially make the work generalizable to other fields.

HIV Digital Vaccine Strategy: Proposal for Applying Blockchain in Preventing the Spread of HIV (Preprint)
Authors: Liu Jia
Published: June 2022

BACKGROUND

The HIV epidemic imposes a heavy burden on societal development. Protection of susceptible populations is the most feasible method for eliminating the spread of HIV. In the absence of a biological vaccine, the definitive solution is enabling susceptible populations to recognize and avoid high-risk sexual behavior.

OBJECTIVE

The objective of this study is to use specific technologies and strategies to establish a system by which high-HIV-risk individuals can determine the HIV infection status of one another anonymously, conveniently, and credibly.

METHODS

This study proposes an HIV digital vaccine (HDV) strategy, a decentralized application (Dapp) based on blockchain for use by individuals with a high risk of HIV and accredited testing agencies (ATAs). Following testing, only the HIV-negative results (or linked information) are uploaded to the blockchain, which results in high-risk individuals being able to determine the HIV-negative status of each other anonymously, conveniently, and credibly.

RESULTS

Future work includes the following: (1) a survey of the willingness to use Dapps among high-HIV-risk populations, (2) a larger framework containing both HDV and people living with HIV (PLH) and discussing the influence of HDV on PLH and its possible solutions, and (3) coordinating with the blockchain development team, ATAs, community-based organizations, and third-party organizations to raise funds, develop the Dapp, formulate detailed plans, and publicize and promote it. The exact timeline for achieving these objectives cannot be determined at present.

CONCLUSIONS

The HDV strategy may reduce the occurrence of high-risk sexual behavior and effectively protect susceptible populations; combined with current strategies, it is a promising solution to prevent the spread of HIV. The included concepts of decentralized surveillance and surveillance as intervention may spark a change in current infectious disease prevention and control modes to introduce beneficial innovations in public health systems globally.

Published: June 2022

BACKGROUND

The recent onset of the COVID-19 pandemic and the social distancing requirement have created an increased demand for virtual support programs. Advances in artificial intelligence (AI) may offer novel solutions to management challenges such as the lack of emotional connections within virtual group interventions. Using typed text from online support groups, AI can help identify the potential risk of mental health concerns, alert group facilitator(s), and automatically recommend tailored resources while monitoring patient outcomes.

OBJECTIVE

The aim of this mixed methods, single-arm study was to evaluate the feasibility, acceptability, validity, and reliability of an AI-based co-facilitator (AICF) among CancerChatCanada therapists and participants to monitor online support group participants’ distress through a real-time analysis of texts posted during the support group sessions. Specifically, AICF (1) generated participant profiles with discussion topic summaries and emotion trajectories for each session, (2) identified participant(s) at risk for increased emotional distress and alerted the therapist for follow-up, and (3) automatically suggested tailored recommendations based on participant needs. Online support group participants consisted of patients with various types of cancer, and the therapists were clinically trained social workers.

METHODS

Our study reports on the mixed methods evaluation of AICF, including therapists’ opinions as well as quantitative measures. AICF’s ability to detect distress was evaluated by the patient's real-time emoji check-in, the Linguistic Inquiry and Word Count software, and the Impact of Event Scale-Revised.

RESULTS

Although quantitative results showed only some validity of AICF’s ability in detecting distress, the qualitative results showed that AICF was able to detect real-time issues that are amenable to treatment, thus allowing therapists to be more proactive in supporting every group member on an individual basis. However, therapists are concerned about the ethical liability of AICF’s distress detection function.

CONCLUSIONS

Future works will look into wearable sensors and facial cues by using videoconferencing to overcome the barriers associated with text-based online support groups.

Authors: Milne-Ives Madison , Rahman Em , Bradwell Hannah , Baines Rebecca , Boey Timothy , Potter Alison , Lawrence Wendy , van Velthoven Michelle Helena , Meinert Edward
Published: June 2022

BACKGROUND

Childhood obesity is a growing global public health concern. Digital tools could encourage behaviour change for healthy lifestyles, but a better understanding of their strategies, adoption, and impact is needed to ensure that available tools actually benefit users. Health Education England developed a digital app (‘NoObesity’) to facilitate and improve communication between families and healthcare providers and to support healthy lifestyle behaviour change.

OBJECTIVE

The aim of the study was to collect evidence about the adoption and implementation of a family-focused app for childhood obesity prevention to inform further development. Specific objectives included examining the app’s usability, acceptability, and perceived impact, identifying barriers to engaging with the app and to changing behaviour, and gathering suggestions for improvement.

METHODS

225 parents were enrolled to evaluate a family app for childhood obesity prevention. Users’ experiences with the app and its perceived impact on motivation, self-efficacy, and behaviours were analysed based on two conceptual frameworks: the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) and Non-adoption, Abandonment and Challenges to the Scale-up, Spread and Suitability (NASSS) frameworks. The study took place between March 2020 and April 2021.

RESULTS

Thematic analysis found that goal-setting, prompts, and suggestions helped support parents’ awareness, motivation, and self-efficacy. Motivation and accessibility were key barriers to behaviour, and engagement was limited by a lack of novel content. Key suggestions included more content and improved notifications and progress tracking. Usability scores were ‘average’ (M = 70·3/100, 95% CI: 63·8-76·8).

CONCLUSIONS

Family-focused mobile health apps have potential as acceptable tools to help support healthy behaviour change and the prevention and management of childhood obesity. Feedback from healthcare professionals could improve families’ motivation and self-efficacy but digital tools will need to integrate into existing routines to enable clinical adoption.

Asymmetric Effectiveness of Monetary and Fiscal Policies: Evidence from Turkey
Authors: Öztürk Cemal , Altınkaynak Günsenin
Published: June 2022

This study assesses the asymmetric effectiveness of Turkey's monetary policy and fiscal policy under the inflation targeting regime in the period of 2006-2020. We employed the non-linear autoregressive distributed lag (NARDL) method and Hatemi-J asymmetric causality test with the assistance of the St. Louis equation, which relates the growth in nominal income with the growth in money supply and public expenditures. The NARDL model revealed that an increase in money supply and gross domestic product (GDP) has a positive relationship. On the other hand, a decrease in money supply and government expenditures have no significant relationship with GDP. In addition, Hatemi-J asymmetric causality results showed an asymmetric causality between money supply and GDP. It demonstrates that the money supply in Turkey during the period 2006-2020 is endogenous.
Employability and Labor Income of Immigrants in the US: A Special Focus on the Roles of Language and Home Country Income Level
Authors: Dudu Selda
Published: June 2022

Speaking the most-demanded languages is an asset in the labor market. However, coming from a high-income country may give immigrants an advantage in the labor market as those may have more transferable skills. This article investigates the determinants of the employability and labor income of immigrants and newcomer immigrants in the United States (US) labor market, specifically focusing on the role of language and income level of the home country. It applies the Heckman two-step selection procedure to the American Community Survey between 2000 and 2019. The findings show that immigrating from both high-income countries and countries where internationally most widely used languages (English, French, Portuguese, Spanish, and Chinese) are spoken gives immigrants an advantage in the US labor market compared to those from the countries where only national languages are spoken. This article emphasizes the key role of the income level of the home country on immigrants' labor income in the US. It contributes to the literature by employing the interaction terms of being from the same-income-level countries and the same-languages-speaking countries.
New Insight into the Substituent Effects on the Hydrolytic Deamination of Saturated and Unsaturated Cytosine
Authors: Uddin Kabir , Islam Md. , Islam Shahidul , Poirier Raymond
Published: June 2022

Ab initio calculations were carried out to understand the effect of
electron donating groups (EDG) and electron withdrawing groups (EWG) at
the C5 position of cytosine (Cyt) and saturated cytosine (H2Cyt) of the
deamination reaction. Geometries of the reactants, transition states,
intermediates, and products were fully optimized at the B3LYP/6-31G(d,p)
level in the gas phase as this level of theory has been found to agree
very well with G3 theories. Activation energies, enthalpies, and Gibbs
energies of activation along with the thermodynamic properties (ΔE, ΔH,
and ΔG) of each reaction were calculated. A plot of the Gibbs energies
of activation (ΔG‡) for C5 substituted Cyt and H2Cyt against the Hammett
σ-constants reveal a good linear relationship. In general, both EDG and
EWG substituents at the C5 position in Cyt results in higher ΔG‡ and
lower σ values compared to those of H2Cyt deamination reactions. C5
alkyl substituents (−H, −CH3, −CH2CH3, −CH2CH2CH3) increase ΔG‡ values
for Cyt, while the same substituents decrease ΔG‡ values for H2Cyt which
is likely due to steric effects. However, the Hammett σ-constants were
found to decrease for both the Cyt and H2Cyt. Both ΔG‡ and σ values
decrease for the substituents Cl and Br in the reaction Cyt, while ΔG‡
values increase and σ decrease in the reaction H2Cyt. This may be due to
high polarizability of bromine which results in a greater stabilization
of the transition state in the case of bromine compared to chlorine.
Regardless of the substituent at C5, the positive charge on C4 is
greater in the TS compared to the reactant complex for both the Cyt and
H2Cyt. Moreover, as the charges on C4 in the TS increase compared to
reactant, ΔG‡ also increase for the C5 alkyl substituents (-H, −CH3,
−CH2CH3, −CH2CH2CH3) in Cyt, while ΔG‡ decrease in H2Cyt. In addition,
analysis of the frontier MO energies for the transition state structures
shows that there is a correlation between the energy of the HOMO‒LUMO
gap and activation energies.

Published: June 2022

Background: Ischemic mitral valve regurgitation is a subgroup
of secondary mitral valve insufficiency that develops due to ischemic
heart disease. The aim of the study is to evaluate the patients who were
operated after acute myocardial infarction for the type of interventions
to be performed for the mitral valve in terms of mortality and
morbidity. Methods: It is a single-centered, retrospective
study. Patients who were admitted to the hospital with the diagnosis of
acute myocardial infarction and operated emergently or urgently between
January 2017 and December 2020 were evaluated. Patients who were found
to have significant IMR (≥ moderate mitral regurgitation) in the early
period and who could achieve complete revascularization were included in
the study. Patients were divided into two groups whether the mitral
valve was intervened or not. Results: The demographical data of
the patients that were included in the study is as follows, 73.4% were
male and 33% were female. The average age of the patients was 63.2 ±
8.9. Patients were compared in terms of significant (moderate or higher)
postoperative residual mitral regurgitation. 62.2% (n=23) of the
patients undergone isolated CABG had mild mitral regurgitation. 5
patients with mitral valve annuloplasty (17.9%) had significant
residual regurgitation (p<0.001). Conlusion: Mitral
valve intervention should not be considered in non-severe mitral valve
insufficiencies (without papillary rupture or chorda rupture) after
acute MI. Preservation of the dynamic structure of the mitral valve
annulus in the acute period makes mitral ring annuloplasty not an
appropriate treatment.
Top Management Team Functional Diversity and Management Forecast Accuracy
Authors: Wang Shan
Published: June 2022

SYNOPSIS

In this study, I examine whether top management team (TMT) between-member and within-member functional diversity affect management earnings forecast accuracy. Between-member functional diversity refers to the heterogeneity of functional experts on a TMT and within-member functional diversity refers to the aggregate functional breadth of TMT members. I find that both types of functional diversity are positively associated with management forecast accuracy. Further cross-sectional analyses show that these positive associations are significant only when firms face greater information uncertainty, when TMTs are more decentralized, and when TMT members have longer joint team tenure. These findings are consistent with the information-processing perspective that TMT functional diversity can facilitate information processing and sharing and thus improve management forecast accuracy. This study contributes to the literature by shedding light on how TMT members with various functional backgrounds work together in shaping financial disclosure quality.

Usability of Language Features of Emails for Detecting Misrepresentations
Authors: Lee Chih-Chen , Welker Robert B.
Published: June 2022

The study experimentally examines the usability of a participant's writing style in email inquiries for fraud (misrepresentation) risk assessment by determining whether auditors can detect appropriate language-based risk factors in an email. The results suggest risk factors are present in emails, but auditors fail to use them for risk assessment. For example, shorter emails arouse skepticism when, in fact, this language feature is an insignificant risk factor. More fitting linguistic-based risk factors are lack of specifics and overuse of qualitative descriptions. Guidance may improve auditors' recognition of appropriate linguistic-based risk factors in email text. Alternatively, risk factors may be too vague to perceive, suggesting a need for techniques to strengthen them in an email inquiry.
Swallowing Activation Using Sensory Stimulation in Patients with Severe Disorders of Consciousness
Authors: Prum Grégoire , Mallart Rémi , Beatrix Margaux , Verin Eric
Published: June 2022

Objective: Swallowing disorders are systematically present in patients with severe brain injury, disorders of consciousness, and subsequently poor quality of life. The study hypothesis was that taste and smell could improve swallowing function and quality of life in such patients, who are fed by gastrostomy tube.Methods: Eight patients with unresponsive wakefulness syndrome were included in this study. All patients had been in a stable state for at least 2 years, and the delay between the neurological event and the study was always more than 2 years. Strong tastes and smells were selected using the Pfister olfactory classification. Taste and smell stimulations were performed every weekday, Monday to Friday, for 1 week (5 sessions) by a speech and language therapist. Evaluation of swallowing was performed before the first session and after the fifth session, and included the number of spontaneous swallows during 10 min, the presence of drooling, and spontaneous tongue and velum mobility.Results: The number of spontaneous swallows at the initial evaluation was 6.8 ± 5.1 n/min. At the final evaluation there was a significant increase in the number of spontaneous swallows (9.1 ± 4.1 n/min, p < 0.01).Conclusion: This clinical observation has shown that taste and smell stimulations are relevant in clinical practice to improve spontaneous swallowing.
Individual differences in adaptability to shiftwork : an exploration of models of shiftwork tolerance
Authors:   , Hill Joanne
Published: June 2022

In order to refine models of shiftwork tolerance, the purported relationships between outcomes and modifiers of the adaptation process were explored. A series of empirical studies amongst shiftworkers, across a variety of work patterns and industries, examined the efficacy of demographic, circadian, personality and work-related variables as predictors of shiftwork tolerance. Trends were shown to be attenuated by shift type, industry type and length of exposure to the shift system.Using a phenomenological approach, Study 1 conducted a series of semi-structured interviews, investigating the aetiology and management of effects through the eyes of shiftworkers themselves. Analysis of recurrent themes supported established trends in the literature and showed some fit with a number of models, highlighting both outcome, and to a lesser extent, modifier variables. New relationships were also identified. Study 2 used this information to design a questionnaire for the collection of more objective data from the same site. Outcomes were capable of being meaningfully reduced into major problem domains. The number and predictive validity of modifiers varied according to the outcome under investigation, with similarities emerging between outcomes that correlated strongly with one another. Using the same approach, Study 3 examined the effect of the type of shift worked. Extent of problems and patterns of prediction showed a strong shift-dependent effect, with reliable trends emerging between those groups involved in nightwork and those not. Study’s 4 and 5 explored the effect of short- (5 weeks) and long-term (12 months) exposure. Longer exposure benefited certain attitude measures and enabled better adjustment of psychological health and sleep quality. Social and domestic disruption and physical health were affected to a similar degree in both studies and therefore, did not benefit from greater exposure. Despite predictive relationships being stronger at follow-up, they were inconsistent over time, suggesting that such interactions are an evolving process.Regardless of the shift type, industry type or length of exposure, attitudes toward shiftwork were most strongly predicted by work-related modifiers, health outcomes by circadian/personality modifiers, and sleep duration by demographic modifiers, suggesting that specific domains are differentially mediated.
Frei Agostinho da Cruz: um poeta para o nosso tempo
Authors: Ventura Ruy
Published: June 2022

A presente comunicação evoca a figura do poeta franciscano Frei Agostinho da Cruz (1540 – 1619), no momento em que se comemoram os 400 anos da sua morte e os 480 do seu nascimento. Agostinho é apresentado como poeta actual cuja leitura é importante num momento civilizacional em que uma crise poliédrica precisa de directores que indiquem os melhores caminhos para alcançarmos a liberdade interior. Transcendendo os lugares comuns da poesia ao divino do seu tempo e mesmo uma linguagem quinhentista, o frade arrábido apresenta uma obra sólida e teotópica que, expondo sem rebuço os conflitos interiores e as psicomaquias do sujeito poético, reflecte sobre a erosão da dignidade humana durante “crise do renascimento”, propondo linhas de fuga universais e sempre contemporâneas, baseadas na “saudade de Deus”.

A theoretical investigation was probed to shed light on the correlation between low detection limit (LOD) in AdSV technique and metal trace complexes stability energy. The study was conducted by means of DFT calculations of copper traces complexation by using three different organic molecules as chelating agents, such as: morin, red pyrogallol and thymolphtalexone. The quantum chemistry calculations were carried out at the B3LYP/6-31G(d) level implemented in Gaussian 09 program package. The results of the electrophilicity index ω indicate that all the studied molecules have a tendency to exchange electron with copper. The negative values of free energy G and enthalpy H show that the complexation reactions are spontaneous in nature and exothermic. According to DFT calculations, copper-red pyrogallol complex with better detection limit (0.07 ng•mL-1) has the lowest total energy (-5100.213 a.u.). Thus, there is a very strong relationship between the total energy of the three complexes and their detection limits in AdSV technique. Hence, the more stable complex has the better detection limit value.

Studies of cyclodextrin chemistry using quantum chemical methods are mainly adopted to investigate the formation of the inclusion complex causing changes in the physicochemical properties of the cyclodextrin guest. In this paper, we conducted a computational modeling study of the inclusion complexes of β-cyclodextrin (β-CD) with m-Methyl Red (m-MR) by using parametric method 6 (PM6), the semi empirical molecular orbital calculations and the natural bond orbital method (NBO). The inclusion process is carried out by maintaining the coordinates of the β-CD fixed and by displacing the guest molecule. The different relative positions between m-MR and β-CD are measured with respect to the distance between the reference atom (N) in the guest molecule and the origin of the coordinates from the equatorial plane of β-CD. The m-MR/β-CD (B) inclusion complex has a lower negative value of ΔG compared to another m-MR/β-CD (A) complex, highlighting the spontaneous behavior of the inclusion process. In addition, during the process of inclusion, the complexation energy is negative, which allows us to affirm that the complexation of m-MR in the β-CD is thermodynamically favorable. Among two directions A and B, the minimum energy generated from the PM6 was obtained in the orientation B and the guest molecule is partially encapsulated in the cavity of β-CD. In the NBO analysis, the stabilization energy is also usually used to characterize the hydrogen bond interaction between a lone pair (LP(Y)) of an atom Y and an anti-bonding orbital (BD٭(X-H)).

Nanostructured “shell-shell” type catalysts, which consist of a magnetically sensitive core of cobalt ferrite and a protective layer of porous SiO2, have been synthesized. On the surface of porous SiO2 clusters of copper oxide are situated playing the role of catalytic centers. The structure of CoFe2O4 / SiO2 / CuO catalyst was confirmed by thermogravimetric analysis (TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Studies of the catalytic activity of the obtained catalysts were performed in the Fenton system on a model solution of methylene blue (MB). The catalytic activity of the composite in MB destruction reaches 99%. The high magnetic sensitivity of the obtained catalysts ensures their easy removal from the reaction medium. The catalysts demonstrated the possibility of reusability without loss of activity.

Continuous production of ethyl acetate involves various separation challenges due to multiple azeotropes. In this study, three-phase advanced distillation method is applied through diverse purification scenarios for ternary separation of ethyl acetate system (ethyl acetate/water/ethanol). This highly non-ideal mixture contains four azeotropes and three distillation regions. To select the best distillation region, the separation feasibility and conceptual design of ethyl acetate three-phase distillation unit are comprehensively investigated by the extended boundary value method for various feed locations and numerous product recoveries. It was found that the region in which ethanol is a stable component was the most suitable region for the distillation process. Further, the conceptual design of the three-phase column is optimized by variation of reflux ratio and operating pressure. Ultimately, based on the conceptual design results, rigorous simulation of the process is accomplished and ethanol is separated with 99.25 mol % purity.

The dynamics of the adsorption process in the fixed-bed column was experimentally studied on the example of the system natural zeolite - water solution of copper salt with low concentrations, which are characteristic for wastewater treatment processes from toxic contaminants. The initial curves of the adsorption process for the height of the sorbent layer of 5 and 7 cm were constructed. The equilibrium of such processes can be described by Henry's linear equation. The adsorption process in the layer consists of two stages, which are examined in the study. The first stage is the formation of concentration front and the second one – its moving. The sum of the time of the first and second stages is the total adsorption time, which is determined before breakthrough time. The first stage of adsorption is mathematically formulated by the differential equation of molecular diffusion with a boundary condition of the first type. The second stage is supplemented by the balance equation, which takes into account not only the change of concentration in time, but also in the vertical coordinate and determines the time of movement of concentration front to breakthrough time. A mathematical model of the adsorption process in a fixed-bed column has been developed. Experimental data and theoretical calculations were compared. The results of statistical calculation of research results showed a satisfactory convergence of experimental and theoretical data.

Sorbent got from leaves and barks of Annona squamosa has been investigated for its sorption capacity towards Methyl Red (MR) utilizing artificially arranged recreated squander waters. Different components influencing adsorption, viz., initial color concentration, contact time, adsorbent dosage, along with the impact of temperature were assessed. The equilibrium of adsorption was demonstrated by Freundlich; Langmuir, Temkin, and Dubinin-Radushkevich isotherms. Pseudo-first order, pseudo-second order, Weber and Morrish intraparticle diffusion, Bangham's pore dispersion and Elovich equations were applied in order to distinguish the rate and kinetics of adsorption progression. Interference of a five-fold abundance of regular anions and cations present in common waters, have been examined. Cation like Ca2+, Mg2+ and Cu2+ have showed some impedance, however, Fe2+ and Zn2+ have synergistically maintained the greatest extraction of the MR. The methods developed were effectively applied to some effluent. The results of experimental data were found appropriate to the pseudo-first order kinetic model. Correlation coefficient (R2) and dimensionless division or separation factor (RL) values have affirmed that adsorption obeys Langmuir adsorption showing monolayer development.
