Breaking the Bargain?

In the wake of the Global Financial Crisis (GFC) and the Great Recession that followed, insecurity emerged as a central theme in elections across the developed democracies. But what drives feelings of insecurity? In this chapter we show that mass perceptions of economic precariousness are shaped not only by individual- and macro-level economic conditions but by political elites as well. Elites take action to buffer the effects of economic downturn through concrete policy efforts. Politicians and party leaders can also help calm insecure voters through their messages, speeches, and rhetoric. Statistical analyses of CSES data show that the financial crisis has both short-term and long-term effect on individuals’ economic perceptions. Furthermore, feelings of insecurity are shaped by elite cues. Party emphases on welfare concerns serve to moderate the impact of individual risk exposure on perceived insecurity. Chapter implications are twofold. First, a complete understanding of its political effects requires taking into account the effect of the crisis at both stages of development and recovery. And second, what matters for feelings of (in)security is less the magnitude of the crisis but elites’ ability to demonstrate an effective response.
Novel Joint-Drift-Free Scheme at Acceleration Level for Robotic Redundancy Resolution With Tracking Error Theoretically Eliminated

In this article, three acceleration-level joint-drift-free (ALJDF) schemes for kinematic control of redundant manipulators are proposed and analyzed from perspectives of dynamics and kinematics with the corresponding tracking error analyses. First, the existing ALJDF schemes for kinematic control of redundant manipulators are systematized into a generalized acceleration-level joint-drift-free scheme with a paradox pointing out the theoretical existence of the velocity error related to joint drift. Second, to remedy the deficiency of the existing solutions, a novel acceleration-level joint-drift-free (NALJDF) scheme is proposed to decouple Cartesian space error from joint space with the tracking error theoretically eliminated. Third, in consideration of the uncertainty at the dynamics level, a multi-index optimization acceleration-level joint-drift-free scheme is presented to reveal the influence of dynamics factors on the redundant manipulator control. Afterwards, theoretical analyses are provided to prove the stability and feasibility of the corresponding dynamic neural network with the tracking error deduced. Then, computer simulations, performance comparisons, and physical experiments on different redundant manipulators synthesized by the proposed schemes are conducted to demonstrate the high performance and superiority of the NALJDF scheme and the influence of dynamics parameters on robot control. This work is of great significance to enhance the product quality and production efficiency in industrial production.

The Characteristics of Laser Welding of a Thin Aluminum Tab and Steel Battery Case for Lithium-Ion Battery

During lithium-ion battery packing, joining between battery cases and tabs is challenging for manufacturers due to dissimilar materials of the battery case and the tab, as well as their thicknesses. Laser welding, which has proven to produce a good weld with high productivity and low electrical resistance, is introduced to weld these materials. The weld was conducted with nanosecond-pulsed fiber laser and the effect of laser powers on mechanical and electrical properties as well as microstructure of the joint is investigated. The weld bead at the low laser power exhibited several blowholes on the surface, while the formation of voids including centerline and root cavities was observed through the cross-section. Moreover, the phenomenon of upward penetration (UP) was observed in all laser powers and recoil pressure which was generated by metal evaporation was supposed to cause the formation of an upward flow of the lower material. A hardness test was performed on both horizontal and vertical directions through the fusion zone. Additionally, the increase of upward penetration (UP) resulted in higher strength and lower electrical resistance of the weld.
Studies on the Prevalence of E. coli in Chicken Carcasses in Abattoirs and its Antibiotic Sensitivity

This study aimed to estimate Butchers hands and articles as a source ofE. coli contamination in poultry meat and slaughterhouses andto estimate the effect of random antimicrobials usage on the antimicrobial susceptibility of the isolated E. coli. A total of 192 samples were collected from four poultry abattoirs in El-Beheira governorate. Samples were collected from butchers' hands, articles, carcass internal and external surfaces. E. coli was isolated and identified by culture, biochemical analysis and PCR. Further the isolates were studied for their antimicrobial susceptibility against 11 commonly used antibiotics in poultry farms. E. coliwas detected in hands (87.5%), articles(81.25%), internal(80.35%) and external (78.57%) surfaces of the carcasses. The highest antimicrobial sensitivity of the isolates were detected to Tobramycin (100%), Cefotaxime (50-75%) and Chloramphenicol (59-66.7%). While, the highest resistance was detected to Penicillin, Sulfamethoxazole and Trimethoprin, (100%), Amoxicillin (93- 100%), Cephradine and Doxycycline. Further, multiple antimicrobial resistance was detected. By PCR, 33.3% (2/6) of the samples from the internal surface of the carcasses were positive for the intimin; eaeA gene. Thus, contamination of chicken carcasses in the abattoirs with pathogenic E. coli that resists different antimicrobials poses a challenge for human food and thus human health. The use of antimicrobials as well asapplying hygienic proceduresin abattoirs are clearly a necessity for the production of healthy food.
Evolution and prospects of the Comprehensive R Archive Network (CRAN) package ecosystem

Free and open source software package ecosystems have existed for a long time, but such collaborative development practice has surged in recent years. One of the oldest and most popular package ecosystems is Comprehensive R Archive Network (CRAN), the repository of packages of the statistical language R, a popular statistical computing environment. CRAN stores a large number of packages that are updated regularly and depend on many other packages in a complex graph of relations. As the repository grows, its sustainability could be threatened by that complexity or nonuniform evolution of some packages. This paper provides an empirical analysis of the evolution of the CRAN repository in the last 20 years, considering the laws of software evolution and the effect of CRAN's policies on such development. Results show how the progress of CRAN is consistent with the laws of continuous growth and change and how there seems to be a relevant increase in complexity in recent years. Significant challenges are raising related to the scale and scope of software package managers and the services they provide; understanding how they change over time and what might endanger their sustainability are key factors for their future improvement, maintenance, policies, and, eventually, sustainability of the ecosystem.
Evaluation of a Framework for Visual-Feedback Training Based on a Modified Self-Organizing Map Using Sensing Information Including Muscle Activity

In this research, we propose a visual-feedback system and evaluate it based on motion-sensing and computational technologies. This system will help amateur athletes imitate the motor skills of professionals. Using a self-organizing map (SOM) to visualize high-dimensional time-series motion data, we recorded the cyclic motion information, including the muscle activities, of a male subject as he pedaled a bicycle ergometer. To clarify the difference between the subject’s motor skill and the target motor skill in a cyclic movement, we used the modified SOM algorithm; a visual-feedback system was developed, which displayed the target motion as a circular trajectory on a two-dimensional motor skills map. The subject trained by observing only the displayed static target trajectory; the subject’s real-time trajectory was constructed from the subject’s real-time motion. We validated our proposed framework for the visual-feedback system by evaluating the motion performance of a subject using feedback training.
Process variation and analysis of FinFET for low-power applications

In today’s microelectronics, FinFET played a leading role to reduce the device dimension at the nanometer scale. The ultra-thin fin on the FinFET device leads to suppression in short channel effect and leakage current that can make a different edge on the performance of the VLSI circuit. In this article, a comprehensive simulation and compact model of 14nm N-type FinFET presented. N-Type FinFET is simulated and analyzed the performance on the different parameters like power dissipation and on-off current ratio (Ion/Ioff) concerning the different oxide material. Further, we analyzed the proposed device performance through the process variation by varying the parameter temperature from 200K to 350K and oxide thickness from 1 nm to 3nm. The high current ratio value of 1010 observed in high-k oxide material in comparison to low-K oxide material that enhance the switching speed of the device in the proposed design along with analyzed the bandgap also. The power dissipation of the proposed design improved upto 38% in comparison to a low-k oxide material.
Mercury contamination and oxidative stress responses in the eye of wild fish (Liza aurata)

Every animal uses the eyes to monitor the surrounding environment and maintain homeostasis. Mercury (Hg) (including methylmercury MeHg) is a pernicious and ubiquitous contaminant in natural waters but the assessment of its potential to interfere with fish eyes is an almost unexplored issue. This thesis will contribute to fill this knowledge gap by the evaluation of mercury accumulation in grey mullet eye wall (Liza aurata) together with the assessment of biochemical endpoints related with the oxidative stress status. This approach was complemented by the characterization of environmental contamination profiles (both in water and sediment). The study was performed at Aveiro lagoon (Portugal), where a well-established mercury historical contamination gradient provides a good background for the assessment of mercury accumulation and its toxic effects under realistic conditions. Sampling was conducted in two sites distancing around 10 km, namely: Largo do Laranjo (LAR) located in the most contaminated area, and São Jacinto (SJ) closer to the lagoon inlet and selected as reference site. Keeping in view that water temperature could affect Hg accumulated levels and biochemical responses, sampling was carried out both in winter (February 2013) and summer (June 2013). L.aurata specimens (n=20) were caught at each site/season and eye wall was removed and preserved in the field. Eye wall was analysed for total Hg and MeHg levels, as well as for antioxidant responses (catalaseCAT, SOD – superoxide dismutase, glutathione peroxidaseGPx, glutathione reductaseGR, glutathione–S-transferase GST) and peroxidative damage (LPO). Inorganic mercury levels were estimated from total mercury and methylmercury levels. Total mercury, inorganic mercury and methylmercury in eye wall were higher at LAR than SJ in winter and summer, reflecting environmental spatial differences of water column and surface sediments. Moreover, fish caught at LAR in winter showed a significant decrease of CAT and SOD, while GST and GR exhibited the same tendency but without statistical support. Peroxidative damage was also recorded as indicated by the LPO enhancement. A much more homogenous spatial pattern was recorded for those biological endpoints in summer, since only the increment of GR and GPx was noticed at LAR. Cause-effect relationships between accumulated mercury (inorganic and methylmercury) were searched by the principal component analysis (PCA). An association between both forms of mercury and GPx and LPO was discerned by PCA. Current data point out the vulnerability of fish eyes to water contaminants, namely mercury. This neurotoxicant can be accumulated in eye wall leading to alterations in the cellular protection against oxidative stress. Such repercussions could eventually compromise fish performance and survival.

In today’s modern world, smart homes are now in demand. The times have now become the thing of the past since, over the last few decades, home automation has gained several milestones and acclaim, mainly limited to sci-fi videos. Compared with days gone by, home automation has brought a whole new definition to life. A controller controlled the devices which can be located at home, such as television, air conditioning, lighting, electric fans, etc. These devices can also be controlled by only one remote control instead of one remote control per system. The problems with this paper solve the problem. Only use an existing Bluetooth transmission with an Arduino and smartphone. The voice recognition using Filipino language was used for automatically controlled the electric fan speed from speed no.1 to speed no. 4. The user makes use of voice commands to perform certain actions. In the testing conducted, the fan speed 1 and 2 obtained 50% accuracy and for speed no.3 and 4 both obtained 100% accuracy. The testing shows a promising result. When it comes to functional testing of the system, the system will function effectively.
Team Performance and Triangle Approach: A Longitudinal Study

ABSTRACT The literature on information systems development appears to be fragmented into three main categories: one that uses a knowledge management perspective, another one that considers social aspects of information systems development, and the last one that emphasizes the role of information technology. Such fragmentation detains the understanding of influential factors. In this paper, we synthesize the prior literature on information systems development and propose a concise model that incorporates all three approaches to assess the relative importance of each category. We empirically tested the model by using a three-wave longitudinal dataset of 64 teams consisting of more than 250 individuals. We found that individual and organizational factors are more important than technological factors. While human capital is the strongest predictor, IT support does not affect team performance. Our findings yield implications for both the theory and the practice.
Graphene Elastomer Electrodes for Medical Sensing Applications: Combining High Sensitivity, Low Noise and Excellent Skin Compatibility to Enable Continuous Medical Monitoring

Continuous monitoring of vital bio-signals is crucial to track the well-being of patients and to allow for timelymedical intervention in cases of emergency. This paper presents a compact and wearable electrocardiogram (ECG) sensor using graphene-elastomer electrodes, which were characterised, first using an electronic patient simulator, then on a human subject. We demonstrate that the proposed electrodes are highly conductive, flexible and ultralight (weighing less than 10 mg). Their skin-impedance values are significantly lower than existing electrodes including other graphene-based sensors. In addition, we demonstrate that they can be applied on the skin in dry form without needing an intermediate gel layer, or excessivemechanical pressures, overcoming an important challenge for long term monitoring applications. The proposed configuration enables the design ofwearable devices that can outperformwell-refined commercial sensors, providing great potential for electronic/mobile health applications.

Detection of Pictorial Map Objects with Convolutional Neural Networks

ABSTRACT In this work, realistically drawn objects are identified on digital maps by convolutional neural networks. For the first two experiments, 6200 images were retrieved from Pinterest. While alternating image input options, two binary classifiers based on Xception and InceptionResNetV2 were trained to separate maps and pictorial maps. Results showed that the accuracy is 95–97% to distinguish maps from other images, whereas maps with pictorial objects are correctly classified at rates of 87–92%. For a third experiment, bounding boxes of 3200 sailing ships were annotated in historic maps from different digital libraries. Faster R-CNN and RetinaNet were compared to determine the box coordinates, while adjusting anchor scales and examining configurations for small objects. A resulting average precision of 32% was obtained for Faster R-CNN and of 36% for RetinaNet. Research outcomes are relevant for trawling map images on the Internet and for enhancing the advanced search of digital map catalogues.
Localized Expression of Aromatase in Human Vascular Tissues

Abstract—The atheroprotective effects of estrogen are well established and the presence of an estrogen receptor in vascular tissues has recently been reported. Therefore, we investigated the localization of the estrogen-producing enzyme aromatase in vascular tissues to assess the possible contribution of endocrine, paracrine, and autocrine modes of action. Aromatase was found in human vascular smooth muscle cells (SMCs) but not in endothelial cells on in situ hybridization. These observations were further supported by quantitative analysis of aromatase mRNA and the activity in 15 human vascular specimens. Only trace levels of expression were detected in the 3 infants examined, whereas 0.0088 to 0.0806 amol/μg RNA of aromatase mRNA and 12.9 to 122.3 fmol · h−1 · mg−1 protein of the activity were detected in 12 of the adult individuals. The switching of tissue-specific exon 1 of the human aromatase gene was also observed in some cases. Aromatase was found to be expressed only in cultured SMCs and not in cul.
An Efficient Least Significant Bit Image Steganography with Secret Writing and Compression Techniques

This paper improves information security on the basis of the traditional LSB steganography by the integration of cryptography and data compression techniques. The proposed method improves the security of information hiding by introducing multiple layers of security processes such as encryption and decryption, compression, and data embedding technique, respectively. This paper employed the Vigenere cipher for the encryption and decryption of the secret file where the generated ciphertext is compressed using the Huffman coding algorithm. The proposed method is tested on three image couriers embedded with 16kB, 32kB, and 48kB secret messages. The empirical results show that the proposed methodology is more competent compared to the traditional LSB image steganography alone with respect to imperceptibility by Peak Signal to Noise Ratio (PSNR), Structural Similarity Index (SSIM), stego image file size, and Mean Square Error (MSE) metrics.
