Published: August 2022

AbstractAimTo review and summarize all the available data from the literature regarding the malignant transformation of oral submucous fibrosis and derive a mean malignant transformation rate (MTR).Materials and MethodsThe electronic search was conducted using PubMed and google scholar. Only full‐text English language articles published from the earliest possible date to 30 April 2019 were included in the study. Abstracts, reviews, letters to editors and editorials were excluded. The study protocol was registered in PROSPERO(CRD42019124563). Data were extracted by 2 reviewers. The random effects model was used to perform the meta‐analysis.ResultA total of 10 articles were included in the review after screening 1177 records. The majority of studies available were from India and Taiwan. Out of 5428 oral submucous fibrosis cases, 298 cases transformed to oral squamous cell carcinoma. Males showed a greater predilection for transformation. The MTR rates varied from 1.9% to 12%. The overall mean MTR obtained based on the available data was 5.5%, and the MTR of India and Taiwan obtained were 5.0% and 5.5%, respectively.ConclusionThe systematic review and meta‐analysis based on the available literature have concluded that patients with OSF have a mean risk of 5.5% for malignant transformation into OSCC.
Wrongs and Sanctions in the Pure Theory of Law
Authors: D’almeida Luís Duarte 
Published: August 2022

AbstractThis short paper addresses a well‐known difficulty in the Pure Theory of Law: the definition of a legal wrong. Kelsen was unable to offer a suitable one, critics say. I agree. But the critics misdiagnosed the problem, and prescribed for it a fruitless solution. The reason for Kelsen’s failure, the critics say, was that he thought the law consists only of sanction‐stipulating norms addressed to officials, and does not comprise duty‐imposing norms addressed to citizens. But the critics are wrong, exegetically as well as substantively. Kelsen did not—and indeed could not—deny that there are such duty‐imposing norms; and it is not the case, in any event, that the admission that there are such norms would enable us to explain the notion of a legal wrong. Kelsen failed to provide an adequate characterization of the notion of a legal wrong, yes, but for a different reason.
Social Entitlements in Habermas’s Discourse Theory of Law: Welfare State Regulations as Legitimizing Institutions
Authors: Späth Stefan 
Published: August 2022

AbstractIn Habermas’s discourse theory of law, the guarantee of citizens’ private and public autonomy is a prerequisite of legitimate law. This includes social entitlements. They provide the living conditions necessary for equal opportunities in the use of private and public freedoms. A proceduralist paradigm of the welfare state ensures private and public autonomy in shaping social rights. This makes welfare state regulations a legitimizing institution. This legal theoretical approach is outlined and defended against objections. The focus falls on examining the critique of the justification and quality of social entitlements. Also considered are possible measures to strengthen the basis of legitimation in shaping social rights.
Productivity effects of corporate income tax: Evidence from China
Authors: Fang Hongsheng , Zhang Xufei , Guo Lin 
Published: August 2022

AbstractWith a persistent global economic slump, governments encourage economic growth by expansionary fiscal policies through tax cuts. Total factor productivity (TFP) is an important determinant of corporate development and economic growth. Taking China's 2008 Corporate Income Tax Reform as a quasi‐natural experiment, this paper uses data from China's A‐share listed companies from 2003 to 2018 and difference‐in‐differences analyses to identify the impact of corporate income tax (CIT) rate changes on TFP. The findings indicate that reducing the CIT rate positively impacts corporate TFP through two available channels: corporate investment and human capital investment. Additionally, the effects of reducing the CIT rate on TFP are primarily significant in non‐state‐owned, smaller and more financing‐constrained enterprises.
Light-Emitting Diode-Based Optical Localization of a Robot in Continuous Motion Using Dynamic Prediction
Authors: Greenberg Jason N. , Tan Xiaobo 
Published: August 2022

Abstract
For mobile robots, localization is essential for navigation and spatial correlation of its collected data. However, localization in Global Positioning System-denied environments such as underwater has been challenging. Light-emitting diode (LED)-based optical localization has been proposed in the literature, where the bearing angles extracted from the line-of-sight of the robot viewed from a pair of base nodes (also known as beacon nodes) are used to triangulate the position of the robot. The state-of-the-art in this approach uses a stop-and-go motion for the robot in order to ensure an accurate position measurement, which severely limits the mobility of the robot. This work presents an LED-based optical localization scheme for a mobile robot undergoing continuous motion, despite the two angles in each measurement cycle being captured at different locations of the robot. In particular, the bearing angle measurements are captured by the robot one at a time and are properly correlated with respect to the base nodes by utilizing the velocity prediction from Kalman filtering. The proposed system is evaluated in simulation and experiments, with its performance compared to the traditional state-of-the-art approach where the two angle measurements in each cycle are used directly to compute the position of the robot. In particular, the experimental results show that the average position and velocity estimation errors are reduced by 55% and 38%, respectively, when comparing the proposed method to the state-of-the-art.
Numerical Investigation of Droplet Generation Within a Microfluidic T-Junction With Semicylindrical Obstacle
Authors: Nath Ashim Jyoti , Deka Dhrijit Kumar , Pati Sukumar 
Published: August 2022

Abstract
We outline a comprehensive computational physics-based investigation of droplet generation characteristics within a double inlet microfluidic T-junction with a semicylindrical obstacle. The interaction of continuous and dispersed fluids triggered by obstacle radius, obstacle position, and the capillary number on the droplet generation is explored in detail. Finite element-based level-set formalism is adopted to track the interface of the two phases in a transient 3D framework. Emphasis has been put to identify the suitable geometrical orientation of the microfluidic confinement for yielding fine spherical droplets with a faster generation rate. The interactions between the pressure forces developed across the obstacle and the amount of continuous fluid striking the dispersed fluid govern the pinch-off phenomenon to yield droplets. The study reveals that the confinement with a larger obstacle radius is susceptible to form fine spherical droplets with a faster generation rate and the production is significantly influenced by the obstacle position. For higher capillary numbers, the dispersed phase goes through extensive elongation before the rupture.

Abstract
Getting access to the state of turbulent flow from limited sensor measurements in engineering systems is a major challenge. Development of technologies to accurately estimate the state of the flow is now possible with the use of machine learning. We present a supervised machine learning technique to reconstruct turbulent vortical structures in a pump sump from sparse surface pressure measurements. For the current flow reconstruction technique, a combination of multilayer perceptron and three-dimensional convolutional neural network is utilized. This technique provides accurate flow estimation from only a few sensor measurements, identifying the presence of adverse vortices. The dependence of the model performance on the amount of training data, the number of input sensors, and the noise levels are investigated. The present machine learning-based flow estimator supports safe operations of pumps and can be extended to a broad range of applications for industrial fluid-based systems.
Effect of damped oscillations in the inflationary potential
Authors: Antony Akhil , Jain Shweta 
Published: August 2022

AbstractWe investigate the effect of damped oscillations on a nearly flat inflationary potential and the features they produce in the power-spectrum and bi-spectrum. We compare the model with the Planck data using Plik unbinned and CamSpec clean likelihood and we are able to obtain noticeable improvement in fit compared to the power-law$$\Lambda $$ΛCDM model. We are able to identify three plausible candidates each for the two likelihoods used. We find that the best-fit to Plik and CamSpec likelihoods match closely to each other. The improvement comes from various possible outliers at the intermediate to small scales. We also compute the bi-spectrum for the best-fits. At all limits, the amplitude of bi-spectrum,$$f_{NL}\,$$fNLis oscillatory in nature and its peak value is determined by the amplitude and frequency of the oscillations in the potential, as expected. We find that the bi-spectrum consistency relation strictly holds at all scales in all the best-fit candidates.
The Lessons Private Schools Teach: Using a Field Experiment to Understand the Effects of Private Services on Political Behavior
Authors: Davies Emmerich 
Published: August 2022

Government services act as important sites of political socialization. Through interactions with the state individuals learn lessons about their value as citizens, form preferences over government services, and understand the value of political participation. What happens when the private sector replaces government provision of basic services? I explore this question in the context of a randomized private school voucher experiment in India. Based on an original household survey of 1200 households, and semi-structured interviews conducted 5 years after the voucher lottery, I find that voucher winning households hold stronger market-oriented beliefs. However, voucher winning households show little difference in political participation on most measures of political participation. I argue that these results are driven by a greater comfort with private providers as permanent economic actors. This suggests exposure to different economic actors, in the form of private schools, have the potential to change political preferences.

Privatisation, a buzzword of the 20th century, has varied approaches; it could be a broad approach of liberalisation to introduce market forces without any change of ownership, termed as ‘partial privatisation’. In narrow terms, it refers to denationalisation or divestiture and change of ownership by sale to private individuals. Public sector in India has grown over the years and operational autonomy has been granted. Disinvestment of government shareholding, has been an annual budgetary exercise; it includes strategic sale. Of late, various disinvestment approaches that are followed include share buyback, cross shareholding offer for sale, follow-on public offer, block deal exchange trade fund. The realisation of disinvestment has been about 56% of the total, and new options have to be explored. Asset monetisation, an approach to encash assets with an objective to raise resources to finance new projects, is planned with an objective to develop infrastructure by involving private sector by following different forms of the publicÐprivate partnership approach. National Monetisation Policy (NMP) has been announced by the government of India to raise ₹600,000 crore over the period of next four years, that is, from 2022 to 25, to cover up the infrastructure gap. As such, monetisation of assetsÑcore as well as non-coreÑwould be a great step in achieving the objective of Atmanirbhar Bharat [self-reliant India], and India to become $5 trillion economy by 2024. Privatisation, liberalisation and asset monetisation appear to be a simple theoretical exercise; it would require planning for newer approaches to attract private funds and also to have political will.

Published: August 2022

Introduction: The purpose of this cross-sectional survey was to examine the possession of low vision reading devices and factors associated with possession of these devices among residents living in a continuing care retirement community. Low vision reading devices are devices other than eyeglasses that aid in reading at near distances. Methods: One hundred and two usable questionnaires were received from residents, ages 65–97 years old, living in the independent and assisted living units of a retirement community. Results: Data indicated that 47% the participants reported having an eye disease, and 53% of the participants owned at least one low vision reading device. The two most common types of devices were handheld magnifiers (40%) and gooseneck lamps with or without a magnifier (26%). Of the 48 participants reported to have eye disease diagnoses, 65% owned a reading device. Forty-six percent of the participants reported having trouble with reading when performing one of the six daily activities even with their reading eyeglasses. The final multivariable logistic regression model indicated that participants who reported having trouble with reading in near distance were significantly more likely to own one of the reading devices. Discussion: This study identified a discrepancy between the high prevalence of visual impairment (i.e., blindness and low vision) among residents living in a retirement community setting and a relatively low number of residents owning low vision reading devices. Findings suggested the key factor contributing to residents’ decision to own reading devices is their level of visual impairment. Implications for Practitioners: Knowing the factors to owning low vision reading devices, occupational therapists may assist residents in continuing care retirement facilities to obtain the appropriate devices.
Orientation and Mobility Practitioners: A Comparison Study of Changes in Demographics

Published: August 2022

Introduction: Three early studies from 1974 to 2000 provided information on demographics and salient characteristics of the profession of orientation and mobility (O&M). The current study compared demographic information from those studies with data from a survey instrument administered in 2019. The purpose of this article is to examine changes in demographics that have emerged in the ensuing years. Method: The questionnaire was disseminated using Qualtrics. It was distributed to practitioners in the profession via all available professional electronic discussion groups and was advertised on the websites of the Academy for Certification of Vision Rehabilitation and Education Professionals (ACVREP) and Association for the Education and Rehabilitation of the Blind and Visually Impaired (AER). Findings: The number of O&M practitioners who responded to the survey was 628. Data indicate that the O&M profession is still predominantly Caucasian, and females continue to be in the majority and have expanded within the profession. The percentage of O&M practitioners working in school settings increased by 14% from earlier studies, and respondents had a median age of 41–50 years. Discussion: The results of this study show that the profession remains primarily female, mostly Caucasian, and 65% of practitioners are 41 year of age or older. O&M practitioners continue serving school-age students, thereby supporting results from previous studies. Finally, salaries of O&M practitioners have positively increased over time after accounting for inflation. Implications for Practitioners: Current characteristics of O&M practitioners have implications for recruitment of more diverse young professionals to serve the diversity of those they teach. It is evident the field should try to increase diversity within its ranks to mirror the diverse population they serve. Moreover, O&M salaries have kept pace or exceeded inflation, and thus the profession continues to be attractive in recruiting qualified and diverse professionals.

Published: August 2022

Introduction: The term “post-traumatic growth” describes positive outcomes that accrue from the struggle with highly challenging life circumstances. The purpose of this study is to describe post-traumatic growth accruing from experience with vision loss caused by age-related macular degeneration (AMD) and to identify the relationships between depression, cognitive processing, social support, and post-traumatic growth. Methods: Individuals with vision loss caused by AMD completed an interviewer-administered composite questionnaire to identify elements of Tedeschi and Calhoun’s theoretical model of the process of posttraumatic growth, including measures of distress (depression), intrusive and deliberate rumination (cognitive processing), and social support (quality and quantity of social ties). Relationships were examined using path analysis. Results: Eighty-nine participants completed the questionnaire (mean age = 85.3 years, range = 74–98 years). All paths, including from depression to social support (β = –.363, p < .001), from social support to deliberate rumination (β = .233; p ≤ .01), and from intrusive rumination to deliberate rumination (β = .514, p < .01), were significant and consistent with the posttraumatic growth theoretical model. Deliberate rumination had a significant direct path to post-traumatic growth (β = .38, p = .001). Discussion: The findings may illuminate elements of the process of post-traumatic growth among those with AMD. We found that as social support increased, depression decreased. Increased social support seemed to encourage positive deliberate rumination, which led directly to post-traumatic growth. Although intrusive rumination is often associated with negative outcomes, the model demonstrates that it also stimulates engagement in deliberate attempts to process one’s experience. Deliberate cognitive processing is a direct precursor to post-traumatic growth. Implications for Practitioners: A focus on the process of growth and thriving can offer a broader view of the experience of living with vision loss. Interventions that foster post-traumatic growth among those with AMD should focus on enhancing social support and facilitating deliberate cognitive processing.

Published: August 2022

Objectives Sinonasal squamous cell carcinomas are rare and aggressive tumors. Curative therapy includes surgery and radiotherapy, with high risk for local morbidity and impaired quality of life. The objective of this study was to analyze a large cohort of patients with sinonasal squamous cell carcinoma on treatment morbidity and oncological outcome. Methods Patients with sinonasal squamous cell carcinoma (n = 75) treated at a tertiary referral center between 2008 and 2019 were identified. In patients with curative treatment intent (n = 70), a chart review and analysis on patient and tumor characteristics, morbidity, and oncological outcome was performed. Results Mean follow-up was 59 months. Primary curative therapy was surgery alone (n = 18), surgery with radiation (n = 25), and primary (chemo)radiation (n = 27). Forty-two (60%) patients suffered from treatment-related morbidity; most frequent symptoms were dry nasal mucosa (20%), nasal obstruction (14.3%), and vision impairment or loss (11.5%). Patients with early disease had less morbidity (51.4 vs 71.1%; P = 0.09), a lower recurrence rate (27% vs. 48.5%; P = 0.08), and better overall survival (92.5% vs. 71.1%; P = 0.01). Conclusion Treatment-related morbidity is common after curative treatment of sinonasal squamous cell carcinomas. Early disease is beneficial in terms of occurrence and severity as multimodal treatment and recurrence can more likely be avoided.
Performance of polylactide biopolymer as matrix material for woven fiber composite laminates

Published: August 2022

The first purpose of this study was, as the first time in the literature, to investigate usability of polylactide (PLA) biopolymer as the matrix of high-performance composite laminated structures having woven forms of glass and carbon fibers. For this purpose, 2-14 layers of 2 × 2 twill Carbon Fiber (CF) and 1 × 1 plain weave Glass Fiber (GF) forms were stacked by PLA powders followed by consolidation of these layers by compression molding technique. After conducting various tests and analysis it was observed that significant improvements in the mechanical and thermal properties could be obtained by laminating PLA with woven CF and GF layers. For instance, mechanical properties obtained for PLA/CF laminates with 14 layers were flexural strength of 641 MPa, flexural modulus of 34 GPa and interlaminar shear strength of 38 MPa. Another purpose of this study was to compare mechanical performance of the PLA matrix laminates with Epoxy matrix laminates having exactly the same type and number of GF and CF layers. It was revealed that mechanical properties of the PLA/CF laminates were approaching to the values of the Epoxy/CF laminates (e.g. flexural strength of 607 and 673 MPa, respectively); while due to poor adhesion between the PLA matrix and Glass Fiber surfaces, the properties were lower in the PLA/GF laminates (e.g. flexural strength of 302 and 553 MPa, respectively). Therefore, it could be generally concluded that, in terms of mechanical performance; traditional thermoset Epoxy matrix could be replaced with the renewable biopolymer PLA matrix in the Woven Carbon Fiber laminates. For the Woven Glass Fiber laminates, a proper sizing treatment with a PLA compatible silane coupling agent would be necessary.
