Backwards time: Causal catachresis and its influence on viewpoint flow

Abstract This paper proposes a cognitive linguistic explanation of the unusual narrative construal of time as moving backwards. It shows that backwards time in narrative involves setting up an alternative space in which a second narrative is constructed simultaneously, resulting in a viewpoint hierarchy which postulates four viewpoints on each discourse statement. The paper draws together research on conceptual metaphor, mental spaces theory and viewpoint multiplicity, bringing it to bear on discourse fragments. The majority of these are taken from Martin Amis’s Time’s Arrow (Amis, Martin. 2003 [1991]. Time’s Arrow. London: Vintage.) (a logically consistent and linguistically revealing text), but the discussion is contextualised with further examples. It is argued that the causal construal implied by narrative is not limited by our phenomenological experience, as other studies (e.g., Evans, Vyvyan. 2013. Language and time: A cognitive linguistics approach. Cambridge: Cambridge University Press.) might suggest, but is instead prompted by conceptual re-interpretation of deictic markers in the discourse. The analysis focuses on causal construal, negation (especially causal catachresis), and alternativity. It shows how linguistic features at the sentential level generate top-down reorganization of both episodic structure and discourse meaning, and how this relies on multiplicity of viewpoint and a conceptual “zooming out” prompting the perception of irony.
Enhancing the Wordpress System: From Role to Attribute-Based Access Control

Role-Based Access Control (RBAC) is the most commonly used model on web applications. The advantages of RBAC are the ease of understanding, applying and managing privileges. The static RBAC model cannot alter access permission in real-time without human involvement and therefore the model suffers from increasing false negative (and/or false positive) outcomes. Hence, the Attribute-Based Access Control (ABAC) model has been proposed to introduce dynamicity and minimize human involvement in order to enhance security. WordPress is a very popular Role-Based content management system. To our best knowledge, no solution to merge from RBAC to ABAC model for WordPress applications has been found. Our contribution is a WordPress plug-in that we have developed to build ABAC upon the existing RBAC setups. In this journey, we have investigated various scenarios by studying different application categories to come up with an enhanced automatic model that adds real-time grant and revoke feature to WordPress.

The scientific article “ The Value of Radiological Methods in Diagnosis of Dysmenorrhea of Puberty ” presents the results of studies using non-invasive diagnostic technologies: magnetic resonance imaging and three-dimensional ultrasonography with color Doppler blood flow imaging (CDI). The evaluation of the features of radiological indices in the patients with dysmenorrhea of functional and organic genesis of severe degree based on the study of the results of 3D ultrasound examination, MRI of small pelvic organs, as well as the state of uterine and endomyometrial blood flow to improve the algorithm of diagnostics has been carried out. A high percentage (51,11%) of the rate of detection of organic pathology in the patients with severe dysmenorrhea (anomalies of the uterus development in the form of bicornuate, saddle, septal, horned, leiomyoma of the uterus body, various forms of endometriosis, combination of leiomyoma and endometriosis of womb) has been stated. Revealed hemodynamic abnormality in the basins of the uterine arteries, the low degree of arterial vascularization of subendomyometrial layer and endometrium, high vascular resistance and rate reduction in blood flow were detected, which is more evident in the patients with functional dysmenorrhea. On the basis of comparative evaluation of informativeness of the research methods, expedience of their use has been substantiated.
Computer-Aided Detection of Lung Nodules in Chest X-Rays using Deep Convolutional Neural Networks

Chest X-Rays are most accessible medical imaging technique for diagnosing abnormalities in the heart and lung area. Automatically detecting these abnormalities with high accuracy could greatly enhance real world diagnosis processes. In this study we aim to improve the accuracy of convolutional deep learning by using Laplacian of Gaussian filtering. In this study, we have used the publicly available Japanese Society of Radiological Technology dataset including 247 radiograms. For improving the performance of convolutional neural networks we used LoG filter and also we used an advanced version of AlexNet and GoogleNet to compare our results. The results indicated that, convolutional neural network with Laplacian of Gaussian filter model produced the best results with 82.43% accuracy. Convolutional neural network with Laplacian of Gaussian filter model is followed by convolutional neural network with an accuracy of 72.97%, followed by GoogleNet model with an accuracy of 68.92%. Out of the four model types utilized, the AlexNet model produced the lowest accuracy with a value of 64.86%. The results obtained here demonstrate that the pre-processing technique like Laplacian of Gaussian filter can improve the accuracy.
DETERMINANTS OF EMPLOYEE COMMITMENT IN CONSTITUTIONAL COMMISSIONS IN KENYA

Demand and supply of manpower is changing in unprecedented proportions. This has resulted in a shortage of knowledge employees and therefore less commitment. Individuals want to stretch their job interests, personality, abilities and fulfillment. Further, these employees are chasing opportunities that will enable them exploit their full potential in the ever changing labour market. Employees who are dissatisfied with their career progress or current situation may consider withdrawing from their organization in favour of better pursuits. The general objective of this research was to identify determinants of employee commitment in constitutional commissions in Kenya. A descriptive cross-sectional survey design was adopted. The target population was 4,771 employees. Simple random sampling was first conducted and then followed by random stratified sampling. A sample of 380 was used. The study relied on primary data collected using structured questionnaires which were pretested to ensure both validity and reliability. Data Analysis was done by using descriptive and inferential statistics. The study found that compensation and reward had a significant effect on employee commitment.

Cellular and Molecular Probing of Intact Transparent Human Organs

Optical tissue transparency permits cellular and molecular investigation of complex tissues in 3D, a fundamental need in biomedical sciences. Adult human organs are particularly challenging for this approach, owing to the accumulation of dense and sturdy molecules in decades-aged human tissues. Here, we introduce SHANEL method utilizing a new tissue permeabilization approach to clear and label stiff human organs. We used SHANEL to generate the first intact transparent adult human brain and kidney, and perform 3D histology using antibodies and dyes in centimeters depth. Thereby, we revealed structural details of sclera, iris and suspensory ligament in the human eye, and the vessels and glomeruli in the human kidney. We also applied SHANEL on transgenic pig organs to map complex structures of EGFP expressing beta cells in >10 cm size pancreas. Overall, SHANEL is a robust and unbiased technology to chart the cellular and molecular architecture of intact large mammalian organs. Graphical Abstract Supplementary Movies of SHANEL are available at http://discotechnologies.org/SHANEL/
Reliability of ABC/2 Method in Measuring of Infarct Volume in Magnetic Resonance Diffusion-Weighted Image

Aims: Manual planimetry is the current method defining infarct volume on magnetic resonance (MR) diffusion-weighted image. ABC/2 method is an ellipsoid geometric formula with advantage estimation of intraparenchymal hemorrhage volume. Our study aimed to find the reliability and reproducibility of ABC/2 method compared to manual planimetric segmentation method. Settings and Design: This was a cross-sectional analytical study with retrospective and prospective data collection. Subjects and Methods: A total of 109 patients with acute ischemic stroke and underwent MR images at Ramathibodi Hospital were retrospectively reviewed. Relationship between manual planimetric segmentation and ABC/2 methods (nonadjusted ABC/2 method and adjusted ABC*/2 method) was determined using Wilcoxon signed-rank test, linear regression analysis, and Bland–Altman plot. Subgroup analysis by location, onset, shape, and size of infarct volume was performed. Interobserver reliability was established using intraclass correlation coefficient and Bland–Altman plot. Statistical Analysis Used: Wilcoxon signed-rank test, linear regression analysis, and Bland–Altman plot were used for statistical analysis. Results: Infarct volume measured with nonadjusted ABC/2 method (23.56, 48.81, 4.25, 0.11, 318.94) (mean, standard deviation, median, minimum, maximum) and adjusted ABC*/2 method (13.37, 28.3, 2.08, 0.06, 170.10) was smaller than manual planimetric method (28.50, 58.64, 5.56, 0.27, 335.49) (P < 0.001). Linear regression's slope confirmed underestimation of volume infarct. In round-to-ellipsoid shape and white matter group, the differences found between nonadjusted ABC/2 and manual planimetric methods are not statistically significant. Conclusions: ABC/2 method is a simple, rapid, and reproducible method with an excellent positive correlation of both adjusted and nonadjusted ABC/2 methods to manual planimetric segmentation method but tendency to underestimated infarct volume. High interobserver reliability and good agreement between two observers have been established. The utilization of nonadjusted ABC/2 method should be used with caution due to its tendency to underestimate the infarct volume.
The Bridge to Inclusion: An Appreciative Strategic Planning Process for the Cultural Awareness Coalition of Midland, Michigan

Inclusive communities are places where all citizens feel a sense of acceptance and belonging. In Midland, MI, a dedicated group of citizens has made a community-wide culture of inclusion their priority. These are the members of the Midland Cultural Awareness Coalition (CAC), a community-based initiative which has attracted a diverse group of stakeholders from a broad cross-section of Midland County. This spring, CAC leaders have collaborated with a team of graduate students (Team Black) enrolled in the University of Pennsylvania’s Master of Applied Positive Psychology program (MAPP). As part of their semester-long course in Applying Positive Interventions in Institutions, Team Black identified CAC’s organizational strengths, identified opportunities, and drew upon their knowledge of positive psychology to create an application that would best support the CAC in pursuit of their vision. The team conducted a situation analysis and researched the academic literature in the fields of coalition effectiveness, goal-setting, inclusion and diversity, bonding and bridging social capital, psychological safety and psychological capital. Team Black recommends the CAC embark upon an Appreciative Inquiry-informed strategic planning process. This process will empower the coalition, engage the community, and provide a bridge from where the CAC is today, to where they hope to be tomorrow. The desired outcomes of this process include: engaging a broader network of stakeholders, creating a common language around inclusion, clarifying the organization’s goal hierarchy, and establishing clear priorities for investing the coalition’s limited human and financial resources.

Scalable Distributed File Sharing System: A Robust Strategy for a Reliable Networked Environment in Tertiary Institutions

The bane of achieving a scalable distributed file sharing system is the centralized data system and single server oriented file [sharing] system. In this paper, the solution to the problems in a distributed environment is presented. Thus, inability to upload sizeable files, slow transportation of files, weak security and lack of fault tolerance are the major problems in the existing system. Hence, the utmost need is to build a client-server network that runs on two or more server systems in order to implement scalability, such that when one server is down, the other(s) would still hold up the activities within the network. And to achieve this reliable network environment, LINUX network operating system is recommended among others as a preferred platform for the synchronization of the server systems, such that every user activity like sending of internal memos/mails, publication of academic articles, is replicated; thereby, achieving the proposed result. Hence, Scalable Distributed File Sharing System provides the robustness required to having a reliable intranet.
Sharpshooters: a review of what moves Xylella fastidiosa

Sharpshooters (Hemiptera: Cicadellidae: Cicadellinae) and spittlebugs (Hemiptera: Aphrophoridae: Aphrophorinae) have a worldwide distribution and are often associated with many crops. Because the geographic range of sharpshooters and spittlebugs often overlaps with the range of the plant pathogenic bacterium Xylella fastidiosa, the importance of these groups of insects in spreading X. fastidiosa rises to the level of a major socioeconomic problem. Managing diseases caused by X. fastidiosa is challenging for several reasons. First, multiple sequence types of the pathogen have been identified, with sequence type affecting host plant specificity. Second, multiple vector species may be present in an agroecosystem, and the host range of vector species is often broad. Although multiple vector control options such as biological, chemical, physical and cultural controls have been described, disease control programs must take into account biological and ecological parameters of locally dominant X. fastidiosa sequence types and vector species to develop suitable control strategies. Our review demonstrates how fundamental principles of vector reproductive biology, behaviour, nutrition and population and community ecology have influenced research on insect vectors and provides insights into priority research areas.

PHOTOTOXIC EFFECT OF VISIBLE BLUE LIGHT ON AGGREGATIBACTER ACTINOMYCETEMCOMITANS AND PORPHYROMONAS GINGIVALIS ISOLATED FROM PATIENTS WITH CHRONIC PERIODENTITIS: AN IN-VITRO EXPERIMENTAL STUDY

Chronic periodentitis is a quite common disease in adult patients characterized by pocket formation and/or recession while progressive loss of periodontal attachment occurs slowly to moderately local risk factors, e.g. bacterial plaque. Wide array of microorganisms have been associated with periodontal disease, out of which Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) have been predominantly associated with periodontal diseases. The objectives of this study were to determine phototoxic effect of visible blue light on Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis clinical isolates from chronic periodentitis patients, and to study their antibiotic sensitivity against selected antibiotics. The test was carried out on 15 strains of Aggregatibacter actinomycetemcomitans and 15 strains of Porphyromonas gingivalis isolated from pockets of chronic periodentitis patients aged between 30-50 years old with pocket depths of 5-6 mm. The bacteria cultured, isolated, and identified by standard bacteriological methods, then subjected to visible blue light at different periods of time exposures. After light exposure, the bacterial killing rates were calculated from colony forming unit (CFU) counts after 48hours of anaerobic incubation. There was a decrease in CFU for both microorganisms as we proceeded from zero, 20, 40 and 60 seconds of blue light exposure. In conclusions, there was a phototoxic effect for the visible blue light emitted from the light curing device against the anaerobic periodontal pathogens and blue light exposure is effective in reducing periodontal pathogens. It is recommended that an adjunctive exogenous photosensitizer be used and that pathogens be exposed to visible light for clinical antimicrobial periodontal therapy.
Functional behavior of AlF3 coatings for high-performance cathode materials for lithium-ion batteries

In response to the ever worsening of the environment by consumption of fossil fuels, energy storage systems like lithium-ion batteries that offer high energy efficiency have evoked a great interest as power sources from portable electronics to electric vehicles. However, the improvement of calendar and cycling life together with safety issues require sophisticated technology to prevent degradation mechanisms. The surface modification of the electrode materials is part of the solution. In this paper, the surface coverage of cathode materials by aluminum fluoride is reviewed. The effect of AlF3 coating on electrochemical performance is examined at various deposit amounts with a comparison of the capacity retention and cycling stability of the different systems proposed in the literature.
Comparison of Neural Network Parameters for Classification of Arabic Handwritten Isolated Characters

The neural network is a static classifier that requires fixed-size vector functions. For this reason, it is considered as a very effective approach for recognizing characters and graphemes. More than 80% of the research that implements neural networks uses backpropagation. The retro-propagating neural network can be used in many applications such as character recognition, face recognition, etc. Training of neural networks is a complex task in the field of supervised research. The main difficulty is to find the most appropriate combination of network architecture, learning function, transfer and training for the classification task. In this paper we dress the recognition of Arabic handwriting isolated characters using two types of neural networks: a feed forward and a cascade forward. We achieve different experiments by varying the number of hidden layer neurons, learning functions, and transfer functions. For that, we use our database for Arabic handwritten characters and ligatures (DBAHCL) in the training, test and validation phases. We compare the results based on the mean squared error, accuracy, convergence rate, and classification accuracy.
