This paper analyzes the universal concept that sonorants are marked geminates in the gemination process of Sylheti Bangla (henceforth SHB). Evidence from SHB suggests that when SHB speakers confront borrowed words with sonorant initial or obstruent initial heterosyllabic clusters, it is invariably the sonorant that gets assimilated. In addition, SHB data indicates that when faced with choices between two sonorants of the heterosyllabic clusters, speakers opt for the less sonorous one for gemination. Given this phenomenon, the proposal that sonorant gemination is absent in SHB could not be the ultimate one as it receives additional support from the fact that SHB also possesses many underlying sonorant geminations. Based on this investigation the hierarchy of the constraints *GG*RR>>*LL*NN is proposed for analyzing the gemination process in SHB. Finally, this paper illustrates some additional constraints in the SHB gemination process found to be necessary.

This article explores the South African government’s national school workbook intervention aimed at addressing poor learner performance in the context of teacher under-preparedness and curriculum reform. It shows how the workbooks use a distance education approach to provide pedagogical and content support for teachers, albeit in the context of classroom teaching, to compensate for teachers’ pedagogical challenges. This article uses a mixed methods research approach to explore how teachers, learners and parents used the workbooks and shows that while the distance educational design scaffolded teaching, additional support is necessary to enable the intervention to be more impactful.

Abstract In-line E-beam inspection may be used for rapid generation of failure analysis (FA) results for low yielding test structures. This approach provides a number of advantages: 1) It is much earlier than traditional FA, 2) de-processing isn’t required, and 3) a high volume of sites can be processed with the additional support of an in-line FIB. Both physical defect detection and voltage contrast inspection modes are useful for this application. Voltage contrast mode is necessary for isolation of buried defects and is the preferred approach for opens, because it is faster. Physical defect detection mode is generally necessary to locate shorts. The considerations in applying these inspection modes for rapid failure analysis are discussed in the context of two examples: one that lends itself to physical defect inspection and the other, more appropriately addressed with voltage contrast inspection.

: The objective of this research is to evaluate the tensile, impact and flexural properties of flax fiber and basalt powder filled polyester composite. Flax fiber is one of the predominant reinforcement natural fiber which possess good mechanical properties and addition of basalt powder as a filler provides additional support to the composite. The Composites are prepared using flax fiber arranged in 10 layers with varying weight percentage of the basalt powder as 5 wt.%, 10 wt.%, 15 wt.%, 20 wt.%, 25 wt.% and 30 wt.% respectively. From the results it is inferred that the composite combination 10 Layers of flax / 5 wt.%, basalt Powder absorbs more tensile load of 145 MPa. Also, for the same combination maximum flexural strength is about 60 MPa. Interestingly in the case of impact strength more energy was absorbed by 10 layers of flax and 30 wt.% of basalt powder. In addition, the failure mechanism of the composites also discussed briefly using SEM studies.

This essay is a study of the nature of moral judgment. Its main thesis is that moral judgment is a type of judgment defined by its content and not its psychological profile. The essay arrives at this thesis through a critical examination of Hume’s sentimentalism and the role of empathy in its account of moral judgment. The main objection to Hume’s account is its exclusion of people whom one can describe as making moral judgments though they have no motivation to act on them. Consideration of such people, particularly those with a psychopathic personality, argues for a distinction between different types of moral judgment in keeping with the essay’s main thesis. Additional support for the main thesis is then drawn from Piaget’s theory of moral judgment in children.

This paper concerns Aristotle’s discussion of practical truth in Nicomachean Ethics VI.2.1139a17–b5. The essay falls into five sections. In the first three, I outline two styles of interpretation of Aristotle’s remarks and suggest that one of them (which I call ‘the third way’) gives a better reading than that offered by its major competitor (which I call ‘the two-component’ view). In the fourth I consider some texts in the remainder of NE VI which provide additional support for the third way of reading. In a brief concluding section, I seek to locate Aristotle’s view of practical truth, so understood, in a broader philosophical context.

The successful treatment of trichotillomania necessitates an initial clinical evaluation of the cognitive, emotional, behavioral, and situational characteristics contributing to an individual’s hair pulling. Assessment also requires a comprehensive psychological/psychiatric interview to assess for comorbid illness, which may either contribute to hair pulling or require separate attention. Several instruments have been designed to assist in quantifying the core symptoms of trichotillomania and can be useful for monitoring treatment progress over time. Treatment approaches include medication, hypnosis, and behavioral therapies, especially modifications of habit reversal therapy. Controlled studies are few in number and are limited to only a few behavioral treatment approaches and medication classes. Research suggests that variations of habit reversal therapy have the greatest efficacy of the interventions investigated thus far. There is additional support for treatment with clomipramine, N-acetylcysteine, and olanzapine, in contrast to multiple other drugs that have been studied or suggested as useful for trichotillomania.

Hyperspectral unmixing is an important technique for analyzing remote sensing images which aims to obtain a collection of endmembers and their corresponding abundances. In recent years, non-negative matrix factorization (NMF) has received extensive attention due to its good adaptability for mixed data with different degrees. The majority of existing NMF-based unmixing methods are developed by incorporating additional constraints into the standard NMF based on the spectral and spatial information of hyperspectral images. However, they neglect to exploit the nature of imbalanced pixels included in the data, which may cause the pixels mixed with imbalanced endmembers to be ignored, and thus the imbalanced endmembers generally cannot be accurately estimated due to the statistical property of NMF. To exploit the information of imbalanced samples in hyperspectral data during the unmixing procedure, in this paper, a cluster-wise weighted NMF (CW-NMF) method for the unmixing of hyperspectral images with imbalanced data is proposed. Specifically, based on the result of clustering conducted on the hyperspectral image, we construct a weight matrix and introduce it into the model of standard NMF. The proposed weight matrix can provide an appropriate weight value to the reconstruction error between each original pixel and the reconstructed pixel in the unmixing procedure. In this way, the adverse effect of imbalanced samples on the statistical accuracy of NMF is expected to be reduced by assigning larger weight values to the pixels concerning imbalanced endmembers and giving smaller weight values to the pixels mixed by majority endmembers. Besides, we extend the proposed CW-NMF by introducing the sparsity constraints of abundance and graph-based regularization, respectively. The experimental results on both synthetic and real hyperspectral data have been reported, and the effectiveness of our proposed methods has been demonstrated by comparing them with several state-of-the-art methods.

Objective: To examine self-rated health and activities of daily living (ADLs) limitations among American Indian and Alaska Native (AI/AN) veterans relative to white veterans. Methods: We use the 2010 National Survey of Veterans and limit the sample to veterans who identify as AI/AN or non-Hispanic white. We calculated descriptive statistics, confidence intervals, and used logistic regression. Results: AI/AN veterans are younger, have lower levels of income, and have higher levels of exposure to combat and environmental hazards compared to white veterans. We found that AI/AN veterans are significantly more likely to report fair/poor health controlling for socioeconomic status and experience an ADL controlling for age, health behaviors, socioeconomic status, and military factors. Discussion: The results indicate that AI/AN veterans are a disadvantaged population in terms of their health and disability compared to white veterans. AI/AN veterans may require additional support from family members and/or Veteran Affairs to address ADLs.

The antigenic drift theory states that influenza evolves via the gradual accumulation of mutations, decreasing a host’s immune protection against previous strains. Influenza vaccines are designed accordingly, under the premise of antigenic drift. However, a paradox exists at the centre of influenza research. If influenza evolved primarily through mutation in multiple epitopes, multiple influenza strains should co-circulate. Such a multitude of strains would render influenza vaccines quickly inefficacious. Instead, a single or limited number of strains dominate circulation each influenza season. Unless additional constraints are placed on the evolution of influenza, antigenic drift does not adequately explain these observations. Here, we explore the constraints placed on antigenic drift and a competing theory of influenza evolution – antigenic thrift. In contrast to antigenic drift, antigenic thrift states that immune selection targets epitopes of limited variability, which constrain the variability of the virus. We explain the implications of antigenic drift and antigenic thrift and explore their current and potential uses in the context of influenza vaccine design.

Abstract Purpose of Review This paper reviews how bone genetics has contributed to our understanding of the pathogenesis of osteoarthritis. As well as identifying specific genetic mechanisms involved in osteoporosis which also contribute to osteoarthritis, we review whether bone mineral density (BMD) plays a causal role in OA development. Recent Findings We examined whether those genetically predisposed to elevated BMD are at increased risk of developing OA, using our high bone mass (HBM) cohort. HBM individuals were found to have a greater prevalence of OA compared with family controls and greater development of radiographic features of OA over 8 years, with predominantly osteophytic OA. Initial Mendelian randomisation analysis provided additional support for a causal effect of increased BMD on increased OA risk. In contrast, more recent investigation estimates this relationship to be bi-directional. However, both these findings could be explained instead by shared biological pathways. Summary Pathways which contribute to BMD appear to play an important role in OA development, likely reflecting shared common mechanisms as opposed to a causal effect of raised BMD on OA. Studies in HBM individuals suggest this reflects an important role of mechanisms involved in bone formation in OA development; however further work is required to establish whether the same applies to more common forms of OA within the general population.
