Does a universal basic income affect voter turnout? Evidence from Alaska

Does a universal basic income (UBI) affect voter turnout? This article argues that the introduction of an unconditional cash payment—where citizens receive money independent of employment status, age, or indigence—can have a turnout-enhancing effect. I evaluate the argument using the introduction of the Permanent Fund Dividend in Alaska. Differences-in-differences estimates covering November general elections from 1978 to 2000 provide compelling evidence that the Alaskan UBI has a significant positive effect on turnout. The results further suggest that the turnout increase was not a one-off effect but persists over a period of almost 20 years. Thus, a UBI has the potential to positively affect turnout among an entire electorate, adding to the discussion around potential welfare reforms in western democracies.
Moisturizers Free of Paraben, Mineral Oil, Alcohol and Ingredients from Animal Origin (Pama) - A New Way Forward

Effective management of dry skin conditions involves the treatment of a defective skin barrier. Moisturizers enhance and preserve the smoothness of the skin in patients with dry skin conditions as well as those with healthy skin. Many ingredients of moisturizers have the potential to cause irritant and allergic contact dermatitis; therefore, it is necessary for clinicians to be aware of such potential allergens to manage and advise their patients’ accordingly. Moisturizers free of paraben, mineral oil, alcohol and ingredients from animal origin (PAMA) have an advantage since they don’t cause sensitivity, allergy or dermatitis. This review will help dermatologists understand the need and benefits of low allergen containing moisturizers.
The Interaction Effect of Text-Based Corporate Innovation and Economic Policy Uncertainty on Firm Performance

Prior research shows that corporate innovation enhances firm value. Using a novel text-based measure of corporate innovation, we explore how the effects of corporate innovation on firm performance change in the presence of economic policy uncertainty. We use a large sample of US firms over the period 1996 to 2010 to test the relationship by executing firm-fixed effect regressions. Our results show that corporate innovation significantly positively affects firm performance. However, our results also reveal that the favorable effect of corporate innovation on firm value is reduced substantially in times of greater economic policy uncertainty. The latter result highlights the urgent need for policymakers to maintain the long-term consistency of economic policies to encourage firms’ innovative activities. Several robustness checks including three proxies for firm performance and four instrumental-variable analyses confirm our original results. JEL Classification: E66, O31, G32
Identification of DDX60 as a Regulator of MHC-I Class Molecules in Colorectal Cancer

Immune checkpoint blockade (ICB) therapies induce durable responses in approximately 15% of colorectal cancer (CRC) patients who exhibit microsatellite instability-high (MSI-H) or deficient mismatch repair (dMMR). However, more than 80% of CRC patients do not respond to current immunotherapy. The main challenge with these patients is lack of MHC-I signaling to unmask their cancer cells so the immune cells can detect them. Here, we started by comparing IFNγ signature genes and MHC-I correlated gene lists to determine the potential candidates for MHC-I regulators. Then, the protein expression level of listed potential candidates in normal and cancer tissue was compared to select final candidates with enough disparity between the two types of tissues. ISG15 and DDX60 were further tested by wet-lab experiments. Overexpression of DDX60 upregulated the expression of MHC-I, while knockdown of DDX60 reduced the MHC-I expression in CRC cells. Moreover, DDX60 was downregulated in CRC tissues, and lower levels of DDX60 were associated with a poor prognosis. Our data showed that DDX60 could regulate MHC-I expression in CRC; thus, targeting DDX60 may improve the effects of immunotherapy in some patients.
Simultaneous Inference on the Korean Won-US Dollar Forward Premium Anomaly

The forward premium anomaly, which refers to the empirical failure of the uncovered interest parity (UIP), has been primarily examined by the forward premium regression of [Fama, E. (1984). Forward and spot exchange rates. Journal of Monetary Economics, 14(3), 319–338. https://doi.org/10.1016/0304-3932(84)90046-1]. Some studies apply the rolling-window regression to capture the time-varying coefficient on the forward premium, with difficulty in statistically testing the deviation of the coefficient from the UIP over time. We follow [Baillie, R. , & Kim, K. (2015). Was it risk? Or was it fundamentals? Explaining excess currency returns with kernel smoothed regressions. Journal of Empirical Finance, 34, 99–111] to apply the simultaneous inference procedure to the Korean Won-US Dollar spot and forward exchange rates by estimating the time-varying coefficient from the kernel-smoothed local-linear regression and constructing the uniform confidence band to test the local deviation. We find that, while the UIP is not rejected from the baseline regression, the simultaneous inference shows that the deviation from the UIP is mainly observed during the early 2000s and 2010s. Time-variation of the forward premium coefficient tends to be significantly affected by economic uncertainties such as the interest rate, inflation, and stock return volatilities in Korea and US.
Combining Inverse Probability Weighting and Multiple Imputation to Improve Robustness of Estimation

Inverse probability weighting (IPW) and multiple imputation are two widely adopted approaches dealing with missing data. The former models the selection probability, and the latter models data distribution. Consistent estimation requires correct specification of corresponding models. Although the augmented IPW method provides an extra layer of protection on consistency, it is usually not sufficient in practice as the true data‐generating process is unknown. This paper proposes a method combining the two approaches in the same spirit of calibration in sampling survey literature. Multiple models for both the selection probability and data distribution can be simultaneously accounted for, and the resulting estimator is consistent if any model is correctly specified. The proposed method is within the framework of estimating equations and is general enough to cover regression analysis with missing outcomes and/or missing covariates. Results on both theoretical and numerical investigation are provided.
INVERSE SPECTRAL-SCATTERING PROBLEM FOR THE STURM-LIOUVILLE OPERATOR ON A NONCOMPACT STAR-TYPE GRAPH

We study the Sturm-Liouville operator on a noncompact star-type graph consisting of a finite number of compact and noncompact edges under standard matching conditions in the internal vertex. We introduce and investigate the so-called spectral-scat\-tering data, which generalize the classical spectral data for the Sturm-Liouville operator on the half-line and the scattering data on the line. Developing the idea of the method of spectral mappings we prove that the specification of the spectral-scattering data uniquely determines the Sturm-Liouville operator on the graph.
The response of a laminar boundary layer in supersonic flow to small-amplitude progressive waves

In this paper the effect of a small-amplitude progressive wave on the laminar boundary layer on a semi-infinite flat plate, due to a uniform supersonic free-stream flow is considered. The perturbation to the flow caused by the wave divides into two streamwise zones. In the first, relatively close to the leading edge of the plate, on a transverse scale comparable with the boundary-layer thickness, the perturbation flow is described by a form of the unsteady linearized compressible boundary-layer equations. In the free stream, this component of flow is governed by the wave equation, the solution of which provides the outer velocity conditions for the boundary layer. This boundary-layer system is solved numerically, and also the asymptotic structure in the far downstream limit is studied. This reveals a breakdown and a subsequent second streamwise zone, where the flow disturbance is predominantly inviscid. The two zones are shown to match in a proper asymptotic sense.
Research on 316 stainless steel low-power pulsed laser-induced arc additive manufacturing by different deposition routes

Abstract In this paper, a low-power pulsed laser-induced arc heat source is used to complete the wire-filled additive manufacturing of multi-layer multi-pass stainless steel walls. The low-power pulsed laser can induce and compress the arc to achieve the concentration of arc energy. This paper systematically studied the effects of different deposition paths on the microstructure and mechanical properties. The results show that the parallel deposition mainly consists of columnar grains, and the grain size of the fine grain area is about 10 μm. The longitudinal tensile strength of the parallel part can reach 620 Mpa, and that elongation is 46%. The horizontal tensile strength is 590 MPa and the elongation is only 40%. The alternating deposition part is mainly composed of oriented dendrites, and the grain size of the fine crystal area is about 12 μm. While the average tensile strength of the alternate part is 585 MPa, the average elongation is 38%. The parallel deposition part has better anisotropy, and the isotropy of the alternate deposited part is better. A parallel deposition path is recommended to choose if the component is required to serve under the unidirectional stress state. An alternate deposition path should be adopted if the component is required to serve under the multidirectional stress state.
Complete Surgical Excision Is Necessary following Vacuum-Assisted Biopsy for Breast Cancer

Vacuum-assisted breast biopsy (VABB) has been replacing excisional biopsy in the treatment of benign breast lesions. Complete surgical excision is still needed for the lesions occasionally diagnosed with breast cancer after VABB. We aimed to characterize residual tumors after VABB and define a subset of patients who do not need surgical excision after VABB. From a retrospective database, we identified patients diagnosed with breast cancer after VABB guided with ultrasonography. Patients who underwent stereotactic biopsies were excluded. We reviewed clinicopathologic data and radiologic findings of the sample. We identified 48 patients with 49 lesions. After surgical excision, the residual tumors were identified in 40 (81.6%) lesions, and there was no residual tumor in nine (18.3%) patients. Imaging studies could not accurately locate residual tumors after VABB. A small tumor size on a VABB specimen was associated with no residual tumor on final pathology. However, residual tumors were identified in four (40%) of 10 lesions with a pathologic tumor size less than 0.5 cm. In conclusion, complete surgical excision remains the primary option for most of the patients diagnosed with breast cancer after VABB. Imaging surveillance without surgery should be carefully applied for selected low-risk patients.
GIBBS MEASURES OF CONTINUOUS SYSTEMS: AN ANALYTIC APPROACH

We present a new method to prove existence and uniform a priori estimates for Gibbs measures associated with classical particle systems in a continuum. The method is based on the choice of appropriate Lyapunov functionals and on corresponding exponential bounds for the local Gibbs specification. Extensions to infinite range and multibody interactions are included.
I Have Two Flags in my Heart: Diasporic Citizenship of Jamaicans Living in Britain

Los pequeños Estados insulares en desarrollo (PEID) y las diásporas se han convertido en actores clave en el ámbito internacional. Este estudio investiga el tema de cómo crear derechos y obligaciones para los jamaiquinos que viven en Gran Bretaña, que sean consistentes con su ciudadanía tanto en las sociedades anfitrionas como de origen, a pesar de sus diferentes obligaciones y responsabilidades con las naciones anfitrionas y de origen. Además, el estudio busca captar la problemática –conflicto o contradicción entre una nueva forma de nacionalismo– del transnacionalismo, y una controvertida forma de ciudadanía –la ciudadanía de la diáspora–. Este estudio está anclado en la teoría de la aculturación y emplea una metodología cualitativa basada en entrevistas estructuradas y grupos focales. El estudio encuentra que, si bien muchos jamaiquinos en Gran Bretaña han encontrado formas de mejorar sus vidas, luchan por tener un sentido de pertenencia a ese país. En segundo lugar, los jamaiquinos en Gran Bretaña son racializados y catalogados como “el otro” a través de percepciones estereotipadas con respecto a sus identidades nacionales. Encuentran consuelo en su identidad jamaiquina para hacer frente a su marginación y exclusión en la sociedad británica. Su ciudadanía diaspórica se aprovecha para desafiar la exclusión en Gran Bretaña. La principal contribución del estudio es proporcionar información sobre el fenómeno migratorio de Jamaica. En general, el estudio sugiere que hay una existencia y resiliencia continua de una comunidad de pertenencia compartida en Jamaica. Este es un recurso vital que debe aprovecharse y comprometerse, dado el potencial de la diáspora para influir en la política exterior británica hacia Jamaica y su papel en el desarrollo de esta.
Moroccan female leaders between femininity and masculinity: A case study of Nabila Mounib (the first female leader of a political party)

Women are ‘intruders’ in the political world, they often find themselves at odds with a world that has established its values and rules according to men’s ways of doing things. When women enter politics, their socially constructed gender clashes with the tough world of politics. Often the feminine style collides with doing political leadership, a leadership that requires toughness, assertiveness and even violence. Women are socially constructed to behave in the complete opposite of this values. The first Moroccan female leader was elected as the head of her political party, Partie Socialist Unifié [PSU], in 2012. Nabila Mounib was faced with the dilemma of how she is going to lead a political party as a female in a patriarchal and conservative society. Should she lead using her feminine leadership style or should she adapt the masculine style that seems to conform with the political world? This paper attempts to explore her leadership style using Feminist Critical discourse analysis FCDA with a focus on the following linguistic features: interruption, hedges and tag questions, and the I vs We.
On validity of the asymptotic expansion approach in contingent claim analysis

Kunitomo and Takahashi (1995), and Takahashi (1997) have proposed a new methodology, called Small Disturbance Asymptotics, for the valuation problem of financial contingent claims when the underlying asset prices follow a general class of continuous Ito processes. It can be applicable to a wide range of valuation problems including complicated contingent claims associated with the Black-Scholes model and the term structure model of interest rates in the Heath-Jarrow-Morton framework. Our approach can be rigorously justified by an infinite dimensional analysis called the Watanabe-Yoshida theory on the Malliavin Calculus recently developed in stochastic analysis.
Tip Vortex Formation and Cavitation

We summarize recent research on the relation between boundary layer flow, tip vortex structure for a finite span wing, and cavitation. Three hydrofoils of elliptic planform of aspect ratio 3 were constructed with different NACA cross sections. Using a sprayed oil droplet technique to visualize the boundary layer flow, each foil was found to have dramatically different flow separation characteristics on both the suction and pressure sides. Careful examination of the tip region suggests that while the initial stages of vortex roll-up from the pressure side are similar for each hydrofoil section, the vortex boundary layer interaction on the suction side differs for each section. The degree of interaction was observed to increase as the lifting efficiency decreased. Over the Reynolds number range tested, tip vortex cavitation inception has been observed to follow an almost universal scaling. Differences in this scaling law are correlated with the degree of vortex/boundary layer interaction.
Bisimple inverse semi-groups

In [1] Clifford showed that the structure of any bisimple inverse semigroup with identity is uniquely determined by that of its right unit subsemigroup. The object of this paper is to show that the structure of any bisimple inverse semigroup with or without identity is determined by that of any of its a-classes. Let us define a right partial semigroup S to be a set S together with a partial binary operation satisfying the following condition: (A) if, for elements a, b, c of S, a(bc) is defined then so also is (ab)c defined and then a(bc) = (ab)c. We say that a right partial semigroup S is isomorphic with a right partial semigroup T if there exists a bijection b of S onto T such that ab is defined if and only if aq bq is defined and such that if ab is defined then (ab)k = aq bb. We define an RP-system (R, P) to be a right partial semigroup R together with a subsemigroup P of R such that: P(1) ab is defined if and only if a E P, for all a, b in R; P(2) R has a left identity contained in P; P(3) ac = bc implies that a = b for all a, b E P, c E R; P(4) foralla,be R,PanPb=Pcforsomece R. It then follows from P(1) and P(3) that any left identity of R contained in P is, in fact, a two-sided identity for P and so is unique. Now consider any a-class R of a bisimple inverse semigroup S. If we define the partial binary operation o in R by the rule that a o b = ab if and only if ab e R, then with respect to this operation R is a right partial semigroup with a subsemigroup P such that (R, P) is an RP-system (Theorem 1.4). Note 1. RP-systems can be obtained from systems having products more generally defined than stipulated in P(1). We then just ignore products which do not satisfy the condition P(1) (cf. Examples 1, 2 in ? 6). Note 2. In particular, R could be a lattice ordered group and P the positive cone of R. We show that for any RP-system (R, P) there exists a bisimple inverse semigroup, which we denote by R-1 o R, some a-class of which is isomorphic with R. Conversely, for any a-class R of a bisimple inverse semigroup S there is a subsemigroup P of R such that (R, P) is an RP-system and R1 o R is isomorphic with S.
Density graded polymer composite foams

This article reviews the main developments associated with density graded polymer composite foams. After a short introduction, a discussion is made on both density graded polymer-based composites and foams separately to better understand the challenges when both structures are combined together to produce composite foams. In all cases, the basic concepts, fabrication methods, main properties and general applications are presented. Opening for future works are also presented to conclude.
Theory of a multimode semiconductor laser with optical feedback

We discuss the derivation of multimode rate equations for the description of a semiconductor laser with external cavity. We adopt a formulation where the complex field amplitudes are coupled to the nonlinear gains. For N lasing modes, this leads to 2 N equations that display in-phased and antiphased time-dependent solutions. A simplified reference model is obtained by assuming that the key parameters are frequency independent. A general linear stability analysis leads to the prediction of two types of Hopf bifurcations. A nondegenerate Hopf bifurcation occurs with the relaxation oscillation frequency as the characteristic bifurcation frequency. A (N21)-degenerate Hopf bifurcation occurs with a lower characteristic frequency. To assess the nature and stability of the solutions emerging from the Hopf bifurcations, we perform a nonlinear stability analysis on a reduced model obtained in the limit of large linewidth enhancement factor. In this asymptotic limit, the steady state is always destabilized in favor of a stable periodic inphased or antiphased state. A numerical analysis yields a bifurcation diagram of the multimode equations, which confirms the analytic results and reveals further complex regimes~quasiperiodic and chaotic, in-phased and antiphased ! as the amplitude of the field fed back into the laser is increased.
On rising Sun von mises and rising Sun wrapped cauchy circular models

Abstract By applying wrapping (Dattatreya Rao et al (2007)), offsetting (Girija et al (2013 and Radhika et al (2013)) and stereographic projection (Phani et al (2012)) have constructed circular models. Further the circular models based on the Rising Sun function are motivated by purely mathematical considerations as a smoothing function and possible application. This work takes a further step in this direction using several mathematical tools such as Real Analysis along with MATLAB and are applied to enlarge the horizon of Mathematical Statistics. Here an attempt is made to construct new circular models using the Rising Sun function and also the circular rising sun lemma is proposed
Income-Based Gaps in College-Going Activities: High School Classes of 1992 and 2004

There has been widespread concern about widening disparities in parental investments that may be associated with widening gaps in educational attainment. Using data from the National Education Longitudinal Study of 1988 and the Education Longitudinal Study of 2002, this study examines parents’ investments and engagement in the college-going process for two cohorts of high school students, focusing on adolescents from low- and high-income families. Between the high school classes of 1992 and 2004, income gaps widened in financial preparation for postsecondary education expenses and student college-admissions test-preparation. In contrast, the income gap in parents-child conversations about the college-going process narrowed, due to a larger increase among low-income parents. I examined potential explanations for growing gaps and found evidence supporting both rising income inequality and changing associations between income and college-going activities. Implications for educational attainment gaps are discussed.
Can Exercise Affect the Pain Characteristics in Patients with Fibromyalgia? A Randomized Controlled Trial

Exercise is often recommended for fibromyalgia. The aim of this study was to investigate the possible influence and change in the pain characteristics of fibromyalgia patients when breathing exercises were added to their exercise program. A total of 106 patients were included and randomly divided into two groups. Τhe first group of patients followed a program of active exercises up to the limits of pain, lasting 30 min with a repetition of two times a week. Patients of the second group followed the same program with the addition of diaphragmatic breaths when they reached the pain limit. The patients completed three questionnaires: the Fibromyalgia Rapid Screening Tool (FiRST), the Brief Pain Inventory (BPI), and the Pain Quality Assessment Scale (PQAS)—once at the beginning, once again after three weeks of exercise, and again 3 months since the beginning of the program. Independent t-tests for the mean total change scores in pain scales demonstrated that for the second group there was a greater improvement in all pain scales, except for the PQAS Deep Pain subscale (p = 0.38). In conclusion, both groups showed significant improvement in all characteristics of the pain scales; however, the improvement of the second group was significantly higher.
