Authors: Mazur Marta , Westland Stephen , Jedliński Maciej , Maruotti Antonello , Nardi Gianna Maria , Ottolenghi Livia , Guerra Fabrizio 
Published: June 2020

Background: Shade matching is a significant treatment step and a challenge for the clinical team with potentially high costs for color correction. Currently, in the United States, the majority of private dental practitioners use visual color matching, but a recent study has reported a high rate of mistakes of subjective color determination among graduate dentists.

Objective: The aim of this retrospective study is to analyze whether a change in the oral background due to dental occlusion can influence tooth color determination.

Methods: Volunteer dental students underwent spectrophotometric color assessment using the SpectroShade device. Two measurements were carried out (with the individuals’ occlusion closed and with the occlusion open) on 43 upper central and 58 lateral incisors. Association between colorimetric variables L*, a*, b* and ΔE00 and tooth width, length and tobacco usage were examined.

Results: Slight changes in the CIELAB values between closed and open occlusions were found for both the gingival and the central sections as for the overall tooth area, with mean ΔL*=-1.24, Δa*=-1.77, Δb*=-1.42 and ΔE00=1,84. A larger difference was detected in the incisal area, with mean ΔL*=-2.99, Δa*=-1.76, Δb*=-2.83 and ΔE00=3.65.

Conclusion: In conclusion, our study showed that dental occlusion does not play a significant role in tooth color matching determinations, even though attention to avoid overbite due to a maximum intercuspation should be made.
The Relationship Between Personality Traits and Coping Strategies in a Sample of Siblings of People With and Without Intellectual Disability: The Mediating Role of Sibling Relationship Quality
Authors: Scigala Dawid K. , Fabris Matteo A. , Longobardi Claudio 
Published: June 2020

Background:
The quality of sibling relationships is an important factor in the development of individuals, particularly in the context of a relationship with a brother or sister with disabilities.

Aims:
This research aims to assess the moderating role of the quality of the relationship with siblings between personality traits and coping strategies.

Methods:
The participants were 187 adults, of whom 97(51.9%) were Individuals with brothers or sisters with intellectual disabilities (S-IDs), aged 18 to 60 years (M=30.22; SD=12.17). The second group was 90 (48.1%) Individuals with typical developmental siblings (S-TDs) aged 18 to 76 years (M=28.56; SD=11.66). Respondents completed the Big Five Questionnaire (BFQ), the Coping Orientation to Problem Experiences (COPE), and the Adult Sibling Relationships Questionnaire (ASRQ).

Results:
The data show a correlation between personality traits and coping strategies. In addition, the size of the ASRQ was found to moderate the relationship between personality traits and coping strategies, albeit in a different way between the two groups.

Conclusion:
The quality of the reality with brothers or sisters turns out to be an important factor in the development, and it is found to mediate the relationship between personality traits and the development of coping strategies, both in S-TDs and S-IDs, presenting similarities and differences. Future research guidelines have been discussed.
Study on the "Phase Hopping" AC-AC Frequency Conversion Method with Approximately Continuous Frequencies
Authors: Xu Zhengwang , Jiang Guozhuang , Kun Ke , Yi Yuchun 
Published: June 2020

Background:
The output voltage frequency for the previously proposed "phase hopping"
AC-AC frequency conversion technology is determined by the law that the number of output voltage
cycles is reduced by one relative to the power frequency in a large cycle containing six jumps.
According to the law, only a limited number of output frequencies, such as 37.5 Hz, 42.86 Hz and
45 Hz are found. Due to the large spacing between the output frequencies, the "phase hopping" frequency
conversion technology is difficult to put into practical use.

Methods:
In this paper, the law of the output frequency control is generalized so that the number of
output cycles in a large cycle is reduced by n relative to the power frequency. The analysis shows
that the appropriate selection of large cycles, including the number of power frequency cycles and
the value of n, can find more frequencies to be used. Reducing the interval between the output frequencies
within 1Hz.

Results:
The analysis results were verified in simulation by MATLAB, and the harmonics and the
feasibility of the actual application were analyzed.

Conclusion:
Finally, an experimental platform was built and an experimental analysis was carried
out. The experimental results show that the theoretical and simulation analyses are correct.

Abstract The unusual observation of the Kondo effect in the two-dimensional electron gas (2DEG) of magnetically undoped AlGaN/GaN heterostructures is reported. The temperature-dependent zero-field resistivity data exhibits an upturn below 120 K, while the standard low-temperature weak localization and then weak antilocalization behaviour is revealed at T → 0. Magnetic transport investigations of the system are performed in the temperature range of 0.1–300 K and at magnetic fields up to 8 T, applied perpendicularly to the 2DEG plane. The experimental data are analyzed in terms of the multichannel Kondo model for d _0 magnetic materials and weak localization theory taking into account the spin-orbit interaction.

Published: June 2020

El presente artículo describe la metodología, resultados y conclusiones derivadas del estudio “Mediaciones Tecnológicas para el desarrollo de la Competencia Semántica Comunicativa- lectura Inferencial en estudiantes de Básica Primaria” desarrollado en la Institución Educativa José María Berástegui, municipio de Ciénaga de Oro, Departamento de Córdoba, con el propósito de potenciar el desarrollo de la competencia semántica comunicativa de la lectura inferencial en estudiantes de tercer grado de básica primaria. A partir de la reflexión de estudiantes, docentes y padres de familia se diseñan ambientes mediados con TIC fundamentados conceptualmente en el Enfoque Semántico Comunicativo. El proceso investigativo se desarrolla en cuatro fases: una fase diagnóstica la cual se estructura a partir del acompañamientos en el aula, evaluación diagnóstica, revisión y reflexión sobre los aspectos registrados en el observador del alumno; los datos obtenidos permiten construir colectivamente un plan de acción , seguidamente se desarrollan las acciones planeadas y se finaliza con la fase de evaluación reflexión sobre el proceso desarrollado, las transformaciones obtenidas en las prácticas de aula y la potenciación en los estudiantes de grado tercero de la básica primaria en lectura inferencial. Conceptualmente se fundamenta en la teoría de Cassany (2006), la cual señala que “Leer es recuperar el valor semántico de cada palabra y relacionarlo con el de las palabras anteriores y posteriores”, en este mismo sentido Van Dijk (1999), establece que la lectura está mediatizada por la memoria social, elementos esenciales en el proceso lector. Los resultados evidencian cambios en la actitud, motivación y participación en las actividades diseñadas a través de TIC, mejorando la comprensión lectora a nivel inferencial. Este diseño de nuevos ambientes de aprendizaje mediados con TIC para la enseñanza de la lectura favorece el aprendizaje cooperativo, colaborativo, el reconocimiento y valoración de los saberes de los estudiantes y el enriquecimiento de los contextos de aula.

Health Gain, Cost Impacts, and Cost-Effectiveness of a Mass Media Campaign to Promote Smartphone Apps for Physical Activity: Modeling Study
Authors: Mizdrak Anja , Telfer Kendra , Direito Artur , Cobiac Linda J , Blakely Tony , Cleghorn Christine L , Wilson Nick 
Published: June 2020

Background
Physical activity smartphone apps are a promising strategy to increase population physical activity, but it is unclear whether government mass media campaigns to promote these apps would be a cost-effective use of public funds.

Objective
We aimed to estimate the health impacts, costs, and cost-effectiveness of a one-off national mass media campaign to promote the use of physical activity apps.

Methods
We used an established multistate life table model to estimate the lifetime health gains (in quality-adjusted life years [QALYs]) that would accrue if New Zealand adults were exposed to a one-off national mass media campaign to promote physical activity app use, with a 1-year impact on physical activity, compared to business-as-usual. A health-system perspective was used to assess cost-effectiveness. and a 3% discount rate was applied to future health gains and health system costs.

Results
The modeled intervention resulted in 28 QALYs (95% uncertainty interval [UI] 8-72) gained at a cost of NZ $81,000/QALY (2018 US $59,500; 95% UI 17,000-345,000), over the remaining life course of the 2011 New Zealand population. The intervention had a low probability (20%) of being cost-effective at a cost-effectiveness threshold of NZ $45,000 (US $32,900) per QALY. The health impact and cost-effectiveness of the intervention were highly sensitive to assumptions around the maintenance of physical activity behaviors beyond the duration of the intervention.

Conclusions
A mass media campaign to promote smartphone apps for physical activity is unlikely to generate much health gain or be cost-effective at the population level. Other investments to promote physical activity, particularly those that result in sustained behavior change, are likely to have greater health impacts.

Published: June 2020

Background and objectives
Nephrolithiasis is a common health problem in autosomal dominant polycystic kidney disease (ADPKD) and significantly contributes to patient morbidity. Recently, Tolvaptan has been introduced for the treatment of ADPKD, but whether it is associated with alterations of the urinary lithogenic risk profile remains unknown.

Design, setting, participants, & measurements
We conducted an analysis of participants enrolled in the Bern ADPKD registry, a prospective observational cohort study. Twenty-four-hour urine analyses were performed at baseline and then at yearly follow-ups. Relative supersaturation ratios for calcium oxalate, brushite, and uric acid were calculated with the program EQUIL2. Unadjusted and multivariable mixed-effects linear regression models, adjusted for age, sex, body mass index, eGFR, net acid excretion, and height-adjusted total kidney volume, were used to assess the association of Tolvaptan with urinary parameters relevant for kidney stone formation. The maximum individual follow-up time was 3 years, median follow-up time 1.9 years, and cumulative follow-up time 169 years.

Results
In total, 125 participants (38 with and 87 without Tolvaptan treatment) were included in the analysis. In multivariable analysis, Tolvaptan treatment was associated [adjusted estimate of the difference between Tolvaptan and no Tolvaptan; 95% confidence interval (CI)] with lower urine relative supersaturation ratios for calcium oxalate (−0.56; 95% CI, −0.82 to −0.3; P<0.001), brushite (−0.33; 95% CI, −0.54 to −0.11; P=0.004), and uric acid (−0.62; 95% CI, −0.88 to −0.37; P<0.001), and with higher urine citrate in mmol/mmol creatinine per day (0.25; 95% CI, 0.05 to 0.46; P=0.02) and calcium in mmol/mmol creatinine per day (0.31; 95% CI, 0.09 to 0.53; P=0.006) excretion. In addition, Tolvaptan treatment was associated with lower net acid excretion in mEq/mmol creatinine per day (−0.54; 95% CI, −0.90 to −0.17; P=0.004) and higher net gastrointestinal alkali absorption in mEq/mmol creatinine per day (0.57; 95% CI, 0.26 to 0.88; P<0.001).

Conclusions
Tolvaptan treatment is associated with a significantly improved urinary lithogenic risk profile in patients with ADPKD.
A Case Study of Effective Tax Rates Using Data Analytics
Authors: Cheng Christine , Sapkota Pradeep , Yurko Amy J. N. 
Published: June 2020

ABSTRACT
Tomorrow's accounting professionals need to understand both accounting and data analytics. To meet these needs, we developed a case that combines an important area of tax accounting, Effective Tax Rates (ETRs), with multiple data analysis skills. The case can be completed in Excel, or with Tableau and/or Alteryx, using Compustat or public data. The case's learning objectives for students are to: (1) expand knowledge of data analytics and ETRs; (2) use critical-thinking skills to identify economic, industry, and firm-level factors that might affect ETRs; (3) develop skills specific to data analytics and data visualization in accounting; and (4) develop effective oral and written communication skills. We evaluate the case's efficacy using data from pre- and post-learning assessment surveys and open-ended responses, which indicate that the comprehensive case meets these learning objectives.
