When Politicians Dodge Questions: An Analysis of Presidential Press Conferences and Debates

There is a pervasive perception that when politicians are asked questions, they rarely answer them. From popular media depictions to rhetorical discourse analyses, we know that politicians tend to dodge questions. However, their means of evading questions remain contested in the literature. Do they more often dodge questions overtly (e.g., “No comment,” “I am here to talk about something else”) or ambiguously? We draw upon equivocation theory (Bavelas, Black, Chovil, & Mullett, 1990) and the concept of “artful dodger” politicians (Rogers & Norton, 2011) to address this phenomenon. We coded 15 years (2000–2014) of U.S. presidential press conference question-and-answer periods (Q&As; N = 235) and 17 years (1996–2012) of presidential debate Q&As (N = 810). In press conferences, presidents were more likely to evade the question with an overt refusal to answer, whereas in debates they were more likely to evade through topical shifts. Furthermore, their evasive patterns seem to occur regardless of whether the question topic is part of their expressed agenda or who
Warthin Tumor-Like Papillary Thyroid Carcinoma with a Minor Dedifferentiated Component: Report of a Case with Clinicopathologic Considerations

Warthin tumor-like papillary thyroid carcinoma is an uncommon variant of papillary thyroid carcinoma. We report a rare case of Warthin tumor-like variant of papillary thyroid carcinoma with a dedifferentiated component consisting of a solid tumor area composed of neoplastic cells with a spindle to tall cell morphology associated with marked nuclear pleomorphism, atypical mitoses, and foci of necrosis. Although our patient presented with a locally aggressive disease (T3 N1b Mo), she is disease-free without radioiodine therapy after a 23-month follow-up period. We emphasize that Warthin tumor-like papillary thyroid carcinoma, like other morphological variants of papillary carcinoma, may occasionally undergo dedifferentiation. As this component may be only focally detectable, we suggest an extensive sampling of all large-sized (>3 cm) papillary thyroid carcinoma. Recognition of any dedifferentiated component in a Warthin tumor-like papillary thyroid carcinoma should be reported, including its percentage, because it may reflect a more aggressive clinical course.
Predictors for advanced liver fibrosis in chronic hepatitis B virus infection with persistently normal or mildly elevated alanine aminotransferase

The aim of the present study was to evaluate the predictors for advanced liver fibrosis in patients with chronic hepatitis B virus (HBV) infection with persistently normal alanine aminotransferase (PNALT), or persistently or intermittently mildly elevated ALT (PIEALT). A total of 305 patients were included in the present study. Liver biopsies were evaluated using the METAVIR scoring system. Liver stiffness (LS) was measured using Fibroscan. Multivariate logistic regression and the area under the receiver operating characteristic curve (AUROC) were used to examine the diagnostic value of the predictors for advanced liver fibrosis. HBV DNA viral load in the PNALT group was significantly lower compared with the PIEALT group (4.57±1.68 vs. 5.71±1.69 log10 IU/ml; P<0.001). Body mass index and LS were also significantly lower in the PNALT group compared with the PIEALT group (P<0.001). The proportion of patients with liver fibrosis was significantly higher in the PIEALT group compared with the PNATL group (P=0.001). High ALT levels were an independent predictor for liver fibrosis, with an odds ratio (OR) of 2.69 (P=0.002). Male sex (OR=0.34, P=0.007), high ALT levels (OR=2.37, P=0.029) and a high HBV DNA load (OR=1.39, P=0.005) were independent predictors for advanced liver fibrosis. The AUROC was 0.65 (P=0.003) when using ALT levels to predict advanced liver fibrosis. ALT levels at ≥0.88 upper limit of normal (ULN; 35 IU/l) were considered as positive for advanced liver fibrosis, the sensitivity and specificity were 87.8 and 47.4%, respectively. The AUROC was 0.64 (P=0.004) when using the HBV DNA value to predict advanced liver fibrosis. When an HBV DNA value of ≥4.99 log10 IU/ml was considered as positive for advanced liver fibrosis, the sensitivity and specificity were 78.0 and 49.5%, respectively. The AUROC was 0.72 (P<0.001) when combining ALT, HBV DNA load and sex into a formulation to predict advanced liver fibrosis. When the formulation score at >-2.22 was considered as positive for advanced liver fibrosis, the sensitivity and specificity were 61.5 and 70.7%, respectively. Therefore, normal ALT levels do not always indicate the absence of hepatic fibrosis. A combination of ALT levels, sex and serum HBV DNA load may more effectively identify patients with CHB at high risk of developing fibrosis. These patients may benefit from liver biopsy.
Speculating to reduce unnecessary power consumption

The power consumption of current processors keeps increasing in spite of aggressive circuit design techniques and process shrinks. One of the reasons for this increase is the complexity of the microarchitecture required to achieve the performance that each processor generation demands. These techniques, such as branch prediction and on-chip level two caches, increase not only the power consumption of the committed instructions, but also the useless power associated with those block accesses that generate results that are not needed for the correct execution and commit of the instructions.In this work, the different accesses that a particular block receives are classified into four different components, based on whether the accesses are performed by instructions of the correct path or the wrong (mispredicted) path, and also based on whether the results of the accesses are needed or not for the correct execution of the instructions. Out of the four components, only one accounts for the useful accesses to the block, that is, accesses performed to correctly execute instructions that will be committed. The other three components account for the useless activity on the block. The simulations performed indicate that, if the useless power dissipation of a high-performance processor could be totally removed with no performance degradation, the overall processor power consumption would be reduced by as much as 65% compared to the same processor in which all the blocks are accessed every cycle.This work then proposes a microarchitectural technique that targets the reduction of the useless power dissipation. The technique consists of predicting whether the result of a particular block of logic will be useful in order to execute the instructions (no matter whether the instructions will be eventually committed or not). If it is predicted useless, then the block is disabled.A case example is presented where two blocks are predicted for low power: the on-chip L2 cache for instruction fetches and the branch target buffer (BTB). The IPC versus power-consumption design space is explored for a particular microprocessor architecture. Both the average and the peak power consumption are targeted. High-level estimations are done to show that it is plausible that the ideas described might produce a significant reduction in useless block accesses. As an example, 65% accesses to the L2 cache can be eliminated at a 0.2% IPC degradation, and about 5% accesses to the BTB can be saved at the penalty of 0.7% IPC reduction.
Perceptions of racial group competition: Extending Blumer's theory of group position to a multiracial social context

Perceptions of threat occupy a central place in race relations in Blumer's theory of prejudice but few direct efforts to study such perceptions exist. Extending Blumer's reasoning, we hypothesize that such perceptions are driven by a group's feelings of racial alienation within the larger social order The more that members of a particular racial group feel collectively oppressed and unfairly treated by society, the more likely they are to perceive members of other groups as potential threats. We also examine whether such perceptions spring from simple self-interest, orthodox prejudice such as negative feelings and stereotyping, or broad beliefs about social stratification and inequality. We use data from the 1992 Los Angeles County Social Survey, a large multiracial sample of the general population, to analyze the distribution and social and psychological underpinnings of perceived group competition. Our results support the racial alienation hypothesis as well as the hypotheses positing effects for self-interest, prejudice, and stratification beliefs. We argue that Blumer's group-position framework offers the most parsimonious integration and interpretation of the social psychological processes involved in the formation of perceptions of group threat and competition. O ) ngoing immigration from Asia and Latin America and the earlier internal migration of African Americans out of the rural South have made most large cities in the United States remarkable multiracial conglomerations (Waldinger 1989). An immediate sociological concern raised by the growing heterogeneity of urban areas is whether members of different groups view one another as direct competitors for scarce economic, political, and social resources (Olzak 1993). Such perceptions may influ
The Effects of Propranolol on Induction of A‐V Nodal Reentrant Paroxysmal Tachycardia

Twelve patients with paroxysmal supraventricular tachycardia (PSVT) were studied before and after administration of 0.1 mg/kg i.v. propranolol. Echo zones for inducing atrioventricular (A-V) nodal reentry were determined using His bundle recording and the atrial extrastimulus technique. After propranolol the echo zone was abolished in two patients, decreased in one, unchanged in five, increased in two. In two patients echo zones appeared only after propranolol. Nine patients had episodes of sustained PSVT prior to propranolol. Following propranolol PSVT persisted in only five. In these five patients propranolol slowed the rate of PSVT.The data were analyzed by plotting A1-A2 and H1-H2 interval curves. On the basis of these curves the patients were separated into those with “dual pathways’ and those with “reflection. ’ The effects of propranolol on both conduction patterns are discussed.In summary, the actions of propranolol in PSVT patients were variable. Potentially beneficial effects included slowing of induced PSVT, loss of the ability to sustain PSVT, and decrease or total elimination of echo zones. Potentially deleterious effects included potentiation of the echo phenomenon with either increase or development of echo zones.
Run-Time Information Visualization for Understanding Object-Oriented Systems

Understanding object-oriented legacy systems is a complex task exacerbated by the presence of late binding and polymorphism. Moreover, the metaphor of message sending and the anthropomorphism promoted by object-oriented languages makes it difficult to statically identify the precise role the objects play at run-time. We propose a lightweight visualization approach enriched with run-time information which allows us to identify precise aspects of the objects lifetime such as the role played in the creation of other objects and the communication architecture they support. Our approach not only supports the run-time understanding of an application but also allows one to evaluate test understanding and test coverage.
Effect of Anodal Transcranial Direct Current Stimulation on Autism: A Randomized Double-Blind Crossover Trial

The aim of this study was to evaluate the Childhood Autism Rating Scale (CARS), Autism Treatment Evaluation Checklist (ATEC), and Children's Global Assessment Scale (CGAS) after anodal transcranial direct current stimulation (tDCS) in individuals with autism. Twenty patients with autism received 5 consecutive days of both sham and active tDCS stimulation (1 mA) in a randomized double-blind crossover trial over the left dorsolateral prefrontal cortex (F3) for 20 minutes in different orders. Measures of CARS, ATEC, and CGAS were administered before treatment and at 7 days posttreatment. The result showed statistical decrease in CARS score (P < 0.001). ATEC total was decreased from 67.25 to 58 (P < 0.001). CGAS was increased at 7 days posttreatment (P = 0.042). Our study suggests that anodal tDCS over the F3 may be a useful clinical tool in autism.
Host–Pathogen Coevolution: The Selective Advantage of Bacillus thuringiensis Virulence and Its Cry Toxin Genes

Reciprocal coevolution between host and pathogen is widely seen as a major driver of evolution and biological innovation. Yet, to date, the underlying genetic mechanisms and associated trait functions that are unique to rapid coevolutionary change are generally unknown. We here combined experimental evolution of the bacterial biocontrol agent Bacillus thuringiensis and its nematode host Caenorhabditis elegans with large-scale phenotyping, whole genome analysis, and functional genetics to demonstrate the selective benefit of pathogen virulence and the underlying toxin genes during the adaptation process. We show that: (i) high virulence was specifically favoured during pathogen–host coevolution rather than pathogen one-sided adaptation to a nonchanging host or to an environment without host; (ii) the pathogen genotype BT-679 with known nematocidal toxin genes and high virulence specifically swept to fixation in all of the independent replicate populations under coevolution but only some under one-sided adaptation; (iii) high virulence in the BT-679-dominated populations correlated with elevated copy numbers of the plasmid containing the nematocidal toxin genes; (iv) loss of virulence in a toxin-plasmid lacking BT-679 isolate was reconstituted by genetic reintroduction or external addition of the toxins. We conclude that sustained coevolution is distinct from unidirectional selection in shaping the pathogen's genome and life history characteristics. To our knowledge, this study is the first to characterize the pathogen genes involved in coevolutionary adaptation in an animal host–pathogen interaction system.
Standardisation of fatwa in Malaysia: management and problems

In a country where jurisdiction over Islam is placed under state administration, standardization is an aspect that continues to be a formidable challenge. In matters of law, difference in provisions creates complications in its implementation. Similarly, with regards to fatwas difference in fatwas between states on a particular legal problem can create confusion to the public. Although the nature of fatwas in itself allows for differences in opinions and decisions on a legal problem, such difference within a small country like Malaysia can lead to adverse consequences. Hence, this article aims to deliberate upon existing methods for the standardisation of fatwas, looking into the effectiveness of its implementation. For this purpose, several examples of differing fatwas which have been gazetted shall be highlighted. Standardisation methods which will be analysed include the method of administrative action, and the method provided for under the latest version of the State Administration of Islamic Law Enactment. This is in relation to fatwas on issues of national interest.

Photoelectric Emission from Interstellar Dust: Grain Charging and Gas Heating

We model the photoelectric emission from and charging of interstellar dust and obtain photoelectric gas heating efficiencies as a function of grain size and the relevant ambient conditions. We employ improved estimates for photoelectric thresholds, yields, and electron capture rates. Using realistic grain size distributions, we evaluate the net gas heating rate for various interstellar environments and find less heating for dense regions characterized by RV = 5.5 than for diffuse regions with RV = 3.1. We provide fitting functions that reproduce our numerical results for photoelectric heating and recombination cooling for a wide range of interstellar conditions. Finally, we investigate the potential importance of photoelectric heating in H II regions, including the warm ionized medium. We find that photoelectric heating could be comparable to or exceed heating due to photoionization of H for high ratios of the radiation intensity to the gas density. We also find that photoelectric heating by dust can account for the observed variation of temperature with distance from the Galactic midplane in the warm ionized medium.
Implementation and application of sub-grid-scale plume treatment in the latest version of EPA’s third-generation air quality model, CMAQ 5.01

The Community Multiscale Air Quality (CMAQ) modeling system Version 5.0 (CMAQv5.0) was released by the U.S. Environmental Protection Agency (EPA) in February 2012, with an interim release (v5.01) in July 2012. Because CMAQ is a community model, the EPA encourages the development of proven alternative science treatments by external scientists and developers that can be incorporated as part of an official CMAQ release. This paper describes the implementation, evaluation, and testing of a plume-in-grid (PinG) module in CMAQ 5.01. The PinG module, also referred to as Advanced Plume Treatment (APT), provides the capability of resolving sub-grid-scale processes, such as the transport and chemistry of point-source plumes, in a grid model. The new PinG module in CMAQ 5.01 is applied and evaluated for two 15-day summer and winter periods in 2005 to the eastern United States, and the results are compared with those from the base CMAQ 5.01. Eighteen large point sources of NOx in the eastern United States were selected for explicit plume treatment with APT in the PinG simulation. The results show that overall model performance is negligibly affected when PinG treatment is included. However, the PinG model predicts significantly different contributions of the 18 sources to pollutant concentrations and deposition downwind of the point sources compared to the base model. Implications: This study describes the incorporation of a plume-in-grid (PinG) capability within the latest version of the EPA grid model, CMAQ. The capability addresses the inherent limitation of the grid model to resolve processes, such as the evolution of point-source plumes, which occur at scales much smaller than the grid resolution. The base grid model and the PinG version predict different source contributions to ozone and PM2.5 concentrations that need to be considered when source attribution studies are conducted to determine the impacts of large point sources on downwind concentrations and deposition of primary and secondary pollutants.
Knapsack Based Optimal Policies for Budget-Limited Multi-Armed Bandits

In budget–limited multi–armed bandit (MAB) problems, thelearner’s actions are costly and constrained by a fixed budget.Consequently, an optimal exploitation policy may not be topull the optimal arm repeatedly, as is the case in other variantsof MAB, but rather to pull the sequence of different arms thatmaximises the agent’s total reward within the budget. Thisdifference from existing MABs means that new approachesto maximising the total reward are required. Given this, wedevelop two pulling policies, namely: (i) KUBE; and (ii)fractional KUBE. Whereas the former provides better performanceup to 40% in our experimental settings, the latteris computationally less expensive. We also prove logarithmicupper bounds for the regret of both policies, and show thatthese bounds are asymptotically optimal (i.e. they only differfrom the best possible regret by a constant factor).
In vivo activation of plasma membrane H(+)-ATPase hydrolytic activity by complex lipid-bound unsaturated fatty acids in Ustilago maydis.

As an adaptation process to the growth retardation provoked by the presence of nonlethal concentrations of ergosterol biosynthesis inhibitors, Ustilago maydis alters the ratio of linoleic to oleic acid bound to plasma membrane complex lipids [Hernández, A. , Cooke, D.T. , Lewis, M. & Clarkson, D.T. (1997) Microbiology 143, 3165-3174]. This alteration increases plasma membrane H(+)-ATPase hydrolytic activity. Activation of H(+)-ATPase by the linoleic/oleic acid proportion is noncompetitive, nonessential and only involves changes in the maximum velocity of the pump. Optimum pH, affinity to MgATP and constants for the inhibition by vanadate and erythrosin B remain unchanged. This all indicates that activation of plasma membrane H(+)-ATPase by unsaturated fatty acids differs clearly from glucose-induced activation observed in yeast. Also, it is a physiologically relevant event similar to other, as yet uncharacterized, changes in plasma membrane H(+)-ATPase hydrolytic activity observed in plants and fungi, as part of an adaptation process to different stress conditions.
Kernel methods for transfer learning to avoid negative transfer

In the big data era, with the devolvement of information storage and processing capability of computers, new tasks become more and more complex and also with higher requirements. In the other side, out-of-date information of old tasks are abounded at will. Due to the considerable cost for classifying the emerged new tasks, transfer learning techniques are developed to extract useful knowledge from existing similar datasets, and a large number of research works have been published in recent years. However, an open problem in transfer learning is the negative transfer which happens due to different distributions among tasks. In this manuscript, we are targeting at proposing a kernel method to evaluate both the task relatedness and the instance similarities. The minimum description length principle MDLP is adopted which was proved effective for evaluating models in transfer learning scenario. Extensive experiments show the effectiveness of our algorithm in terms of the classification accuracy in real datasets.
