Subject-verb agreement mismatches have been reported in the L2 and heritage literature, usually involving infinitives, analyzed as default morphological forms for fully specified T-heads. This article explores the mechanisms behind these mismatches, testing two hypotheses: the default form and the surface-similarity hypotheses. It compares non-finite and finite S-V mismatches with subjects with different persons, testing whether similarity with other paradigmatic forms makes them more acceptable, controlling for the role of verb frequency. Participants were asked to rate sentences on a Likert scale that included (a) infinitive forms with first, second and third person subjects, and (b) third person verbal forms with first, second and third person subjects. Two stem-stressed verbs (e.g., tra.j-o ‘brought.3p.past’) and two affix-stressed verbs (e.g., me.ti-o ‘introduced.3p.past’), varying in frequency were tested. Inflectional affixes of stem-stressed verbs are similar to other forms of the paradigm both phonologically and in being unstressed (tra.j-o ‘brought.3p.past’ vs. trai.g-o ‘bring.1 p.pres’), whereas affixes of affix-stressed verbs have dissimilar stress patterns (me.ti-o ´introduced.3p.past’ vs. me.t-o ‘introduce.1p.pres’). Results show significantly higher acceptability for finite vs. non-finite non-matching, and for 1st vs. 2nd person subjects. Stem-stressed verbs showed higher acceptability ratings than affix-stressed ones, suggesting a role for surface-form correspondence, partially confirming previous findings.

This chapter compares the unitary executive at the federal level with the plural executive at the state level. The fifty state constitutions and the United States Constitution share a “surface similarity” in describing the authority of their chief executives: They both vest executive power in a governor or president. But in practice, there are many differences. At the national level, the US Constitution places all executive authority in one president who controls the executive-branch officers through the singular authority to choose all cabinet members. What’s called a unitary executive largely is one, given the president’s authority to hire and fire these executive branch officers. Contrast the state side. In response to the states’ colonial experiences with a monarch, many of the first state constitutions created weak executive branches. All but one of the original state constitutions also mandated that the governor work alongside an executive council. In many states, constitutional executive offices—secretary, treasurer, auditor—are often chosen by the legislature. The rise of the state attorneys general as a source of local and national power offers one illustration of the salience of the plural executive.

AbstractThree dimensional (3D) coronary anatomy, reconstructed from coronary angiography (CA), is now being used as the basis to compute ‘virtual’ fractional flow reserve (vFFR), and thereby guide treatment decisions in patients with coronary artery disease (CAD). Reconstruction accuracy is therefore important. Yet the methods required remain poorly validated. Furthermore, the magnitude of vFFR error arising from reconstruction is unkown. We aimed to validate a method for 3D CA reconstruction and determine the effect this had upon the accuracy of vFFR. Clinically realistic coronary phantom models were created comprosing seven standard stenoses in aluminium and 15 patient-based 3D-printed, imaged with CA, three times, according to standard clinical protocols, yielding 66 datasets. Each was reconstructed using epipolar line projection and intersection. All reconstructions were compared against the real phantom models in terms of minimal lumen diameter, centreline and surface similarity. 3D-printed reconstructions (n = 45) and the reference files from which they were printed underwent vFFR computation, and the results were compared. The average error in reconstructing minimum lumen diameter (MLD) was 0.05 (± 0.03 mm) which was < 1% (95% CI 0.13–1.61%) compared with caliper measurement. Overall surface similarity was excellent (Hausdorff distance 0.65 mm). Errors in 3D CA reconstruction accounted for an error in vFFR of ± 0.06 (Bland Altman 95% limits of agreement). Errors arising from the epipolar line projection method used to reconstruct 3D coronary anatomy from CA are small but contribute to clinically relevant errors when used to compute vFFR.

Steganography using image interpolation has created a new research area in multimedia communication. A reversible data concealing in HSI and CMY color models using image interpolation is proposed in this paper. The HSI and CMY image models are interpolated using High Capacity Reversible Steganography (CRS) technique. The median plane of both HSI and CMY color models are selected for secret message bit concealing. The secret message bits are concealed in the cover plane by Exclusive OR (XOR) operation. Since the cover image is recovered after secret message bit retrieval, this finds application in military and medical imaging applications. The experimental results of proposed scheme showed very high embedding capacity of about 16 bits in each pixel location of calculated pixel value, good image quality with a surface similarity index measure (SSIM) value 1 and high PSNR. Also, high robustness is achieved on comparing with the existing works.

Near surface turbulent momentum flux estimates are performed over the Aegean Sea, using two different approaches regarding the drag coefficient formulation, a wave boundary layer model (referred here as KCM) and the most commonly used Coupled Ocean–Atmosphere Response Experiment (COARE) algorithm. The KCM model incorporates modifications in the energy-containing wave spectrum to account for the wave conditions of the Aegean Sea, and surface similarity to account for the stratification effects. Airborne turbulence data during an Etesian outbreak over Aegean Sea, Greece are processed to evaluate the simulations. KCM estimates found up to 10% higher than COARE ones, indicating that the wave-induced momentum flux may be insufficiently parameterized in COARE. Turbulent fluxes measured at about 150 m, and reduced to their surface values accounting for the vertical flux divergence, are consistently lower than the estimates. Under unstable atmospheric stratification and low to moderate wind conditions, the residuals between estimates and measurements are less than 40%. On the other hand, under stable stratification and strong winds, the majority of the residuals are more than 40%. This discrepancy is associated with the relatively high measurement level, shallow boundary layer, and the presence of a low level jet.

Abstract The purpose of this research is to examine thin-film nanomaterial movement in three dimensions over a stretchable rotating inclined surface. Similarity variables are used to transform fundamental systems of equations into a set of First-order Differential Equations. The Runge-Kutta Fourth Order approach is utilized for numerical purpose solution. Variable thickness., Unsteadiness parameter., Prandtl number., Schmidt number., Brownian-motion parameter., and Thermophoretic parameter have all been seen to have an impact. Physically and statistically, the indispensable terms namely Nusselt as well as Sherwood numbers are also investigated. As the dimensionless factor \(S\) grows, the temperature field decreases. The momentum boundary layer is cooled when the parameter \(S\) is improved, and the opposite effect is observed for Nusselt number. A greater Schmidt number Sc reduces the Sherwood number by increasing the kinematic viscosity as well as Concentration of the chemical species. Further, the RK4 method is also validated with the HAM approach. Furthermore, we verified the acquired results by establishing a comparison with previous literature, and we discovered an outstanding match, confirming the accuracy of the current communication.

Our study aims to determine whether formal similarity between two languages (operationalized via the Feature Reassembly Hypothesis) allows adult L2 learners of French (Spanish native speakers; NSs) to straightforwardly acquire third-person singular accusative clitics in their L2. Additionally, we examined the role of surface similarity, since French and Spanish overlap and diverge in several ways. In terms of formal similarity, third-person accusative clitic pronouns in Spanish are almost perfect analogues of their French counterparts. In terms of surface similarity, however, while the feminine accusative pronouns are identical (“la” [la]), the masculine ones differ in Spanish (“lo” [lo]) and French (“le” [lǝ]). Participants included French NSs (n = 26) and Spanish-speaking L2 French learners (n = 36). Results from an offline forced-choice picture selection task and an online self-paced reading task did not support the Feature Reassembly Hypothesis because learners showed considerable difficulty with the interpretation and processing of these pronouns, revealing that, unlike French NSs, their interpretations and processing are guided by the feature [±Human] and, to a lesser degree, by gender, which might be due to the surface-level similarity between feminine accusative clitic pronouns in both languages.

Abstract This article reports an empirical study investigating whether English and Spanish speakers can reconstruct thematic structures in their second language (L2) grammars of Chinese Double Object Constructions. Data collected from an acceptability judgement task and an animation matching task suggest that learners are able to reconstruct L2 grammars to accommodate new target properties. However, it is also found that learners have difficulty removing thematic relations transferred from their first language (L1), implying that adult L2 grammars might permanently deviate from grammars of native speakers. The difficulty is accounted for on the basis of Yuan's (2014) Dormant-Feature Hypothesis, which assumes Full Transfer and that if the input provides no evidence confirming or disconfirming the transferred property, the property will lose its vigour and become dormant. This dormant status leads to random behaviours in L2 judgements and interpretations. This is confirmed in this study, in which English speakers are found to transfer one interpretation of indirect objects from their L1 and Spanish speakers are found to transfer two interpretations from their L1 that are not instantiated in the target language Chinese. Due to the misleading evidence in the Chinese input that shares surface similarity with the transferred property, English speakers are hindered from restructuring their L2 grammars, and the transferred interpretation remains active. On the other hand, the absence of informative evidence in the Chinese input leaves the two transferred interpretations to a dormant status in Spanish speakers’ L2 Chinese grammars.

Purpose of the study: This study compared the effect of paternalistic leadership on employee voice and silence motives based upon gender-based similarity attraction account among employee-leader dyads in Higher Educational Institutions (HEI). The study was conducted in public sector universities of Balochistan, Pakistan. Methodology: The Study used Partial least squares–structural equation modelling, along with advanced methods for multi-group analysis, to assess and compare the proposed relationships between the gender similar and dissimilar dyads. Main findings: The results of this study revealed significant differences between groups for the effect of the authoritative dimension of paternalism on pro-social silence, benevolence dimension of paternalism on quiescence silence and quiescence voice, and morality dimension on opportunistic silence. Application of the study: The current study might help HEI authorities in understanding the effects of paternalistic leadership and diversity management. Novelty/Originality of the study: This study makes a significant theoretical contribution by comparing the effect of paternalistic leadership on voicing motives of employees based on similarity attraction account between gender similar and dissimilar leader-subordinate dyads.

Unlike many of my other papers in which I analyzed the ways actions are performed, this paper was built around an identifiable formulation. While there is considerable appeal in collecting words, expressions, or formulations to see how they function and what actions they perform, there are, in my view, two significant problems in doing so. The first is that although there is surface similarity in the collection, the items may function very differently and should not be in one collection. Various instances put under the rubric of Extreme Case Formulations are integral parts of different actions. The second problem is related to the first. In studying interaction, we appreciate that fact that interactants perform specific actions, moment to moment, in the course of engaging in activities. When we consider the choices or selections that participants make, those choices generally are in terms of the various ways of performing, or not performing, a relevant action in that sequential environment. However, when we put together a collection of objects, such as Extreme Case Formulations, that service quite different actions and activities, we are focused away from the fact that the Extreme Case Formulations are but one way of working to accomplish the local action, with other ways as alternatives. Instead, papers that are built around a word or phrase or formulation usually are organized to reflect some number of ways that the term or expression or formulation is used....
