Mortality rate of striped marlin (Tetrapturus audax) caught with recreational tackle

A project was initiated in the autumn of 2000 to document the mortality of striped marlin caught on recreational fishing tackle, with a follow-up study conducted in autumn of 2001. Fish were caught using typical recreational fishing methods and 80 pop-up satellite archival tags were deployed with new software and mechanical release mechanisms that allowed tags to detach and transmit early if the fish died. The first year study was also designed to compare the effectiveness and associated mortality of circle hooks versus J-hooks, while the second year study compared offset and non-offset circle hooks. All fish were caught on live bait. Circle hooks were found to be equally effective in hooking and landing striped marlin and far less likely to cause serious bleeding or become lodged in areas other than the mouth. Non-offset and 5° offset circle hooks had very similar performance. Depth and temperature records allowed us to determine the fate of individual marlin following release. In total, 16 of 61 fish died (mortality rate of 26.2%), all within 5 days of release (mean 1.5 days). Injury was a clear predictor of mortality; 100% of fish that were bleeding from the gill cavity died, 63% of fish hooked deep died, and 9% of those released in good condition died.
The surprising lack of connection between social networks and the enterprise success of ultra-religious female micro-entrepreneurs

Purpose The utilization of social networks is known to have an impact on micro-enterprise success. This study aims to examine the contribution of social networks in acquiring resources and their role in the enterprise’s success. Design/methodology/approach A business’s success is influenced by its network structure and the network’s resources. The authors examine whether unique religious-cultural characteristics affect the social networks contribution to a business’s success. This model examines the network utilization of women entrepreneurs who own micro-enterprises in ultra-religious groups. The sample consists of 123 surveys completed by Jewish ultra-Orthodox women entrepreneurs in Israel. Data collection was conducted between February and June 2013. The authors used a snowball sampling approach where interviewees were asked to refer us to other entrepreneurs. In the hour-long interview, a questionnaire was used with open and closed questions. Findings Findings indicate that strong personal ties provide a micro-enterprise with social legitimacy, emotional support and assistance in the management and operation of daily activities. However, contrary to the existing literature, network utilization did not contribute to enterprise success. That is, in religious communities in particular, social networks enable the existence of businesses, but do not contribute to their success. Practical implications The practical implications of this paper are the mapping of the social network resources used by the business owner, such as financial consultations or professional assistance, as well as distinguishing between strong and weak ties, which reflect the intensity of the contact for better use of the social network by the entrepreneurs. Originality/value This study examined social networks’ contribution to the acquisition of resources, as well as the part they play in the success of ultra-orthodox women micro-entrepreneurs and perhaps other religious and minorities groups.
TISSUE-SPECIFIC EFFECT OF MERCURY ON ANTIOXIDANT DEFENSE SYSTEM AND PROTECTIVE ROLE OF SELENIUM ON MERCURY-INDUCED OXIDATIVE STRESS IN BLUE MUSSEL Mytilus galloprovincialis (Lamarck 1819)

Mercury (Hg), one of the most toxic environmental and industrial pollutants, is receiving increased attention globally because of human health and environmental concerns. In the present study, we investigated the toxic effect of Hg in the absence or presence of selenium (Se) on the antioxidant enzymes in different tissues, such as hepatopancreas and gills, of mussels M. galloprovincialis after their exposure for 6 days. Mussels were exposed to Hg (25 mu g L(-1)Hg2(+)), Se (4 mu g L-1 Se4+) and the mixture (25 mu g L-1 Hg2++4 mu g L-1 se(4+)) of the former two elements. Similar effect was found in the activities of superoxide dismutase (SOD) and glutahione peroxidase (GPx) which initially increased and subsequently decreased with the duration of exposure time in hepatopancreas and gills tissues of blue mussels exposed to metals; CAT was significantly inhibited by Hg from 4th day in hepatopancreas but no significant change was found in gills. Activities of antioxidant enzymes in Se-treated mussels were significantly elevated compared with Se-free mussels including control and Hg-treated groups. The result of the statistical evaluation showed that apparent tissue-specific effect was found in antioxidant enzyme activities in mussels exposed to Hg and the induction of key antioxidant defenses as a result of selenium supplementation might play an important role in protection of aquatic organisms against oxidant stress caused by heavy metals.
Moving Forward with the BAS: Towards a Neurobiology of Multidimensional Model of Approach Motivation

One of the hottest topics in neuroscience is the study of brain-behavioural circuits underlying the processing of reward-related stimuli. A growing body of studies has shed new light on the neural structure of this reward system. In this paper, we discuss the significance of these studies from the perspective of a neuropsychological theory of personality, namely the Reinforcement Sensitivity Theory (RST). RST assumes that variation in sensitivity/reactivity of the reward system is the cause of individual differences in approach motivation (e.g. desire or need for achievement, persistence, and positive emotionality). Within RST, these individual differences are contained in the construct of the Behavioural Approach System (BAS). However, there is an ongoing debate as regards the nature of the BAS. This fact motivated us to review the latest refinements in the neuroscience of the BAS in the context of the reward system. In this review, we identity four distinctive aspects of the BAS: wanting, incentive motivation, striving and liking. Their behavioural effects are compared with the behavioural manifestations of testosterone, dopamine, serotonin and endogenous opioids, respectively. We conclude that the unidimensional view of the BAS is overly oversimplified; and we suggest that it should be studied as a multidimensional construct and, by implication, so too should the reward system.
A new approach to a model of the mammalian retina with optically programmable logic cells

This paper reports a model of the mammalian retina as well as an interpretation of some functions of the visual cortex. Its main objective is to simulate some of the behaviors observed at the different retina cells depending on the characteristics of the light impinging onto the photoreceptors. This simulation is carried out with a simple structure employed previously as basic building block of some optical computer architectures. Its possibility to perform any type of Boolean function allows a wide range of behaviors.
Ba ery-free 802.15.4 Receiver

We present the architecture of an 802.15. 4 receiver that, for the rst time, operates at a few hundred microwatts, enabling new batteryfree applications. To reach the required micro-power consumption, the architecture diverges from that of commodity receivers in two important ways. First, it o oads the power-hungry local oscillator to an external device, much like backscatter transmitters do. Second, we avoid the energy cost of demodulating a phase-modulated signal by treating 802.15. 4 as a frequency-modulated one, which allows us to receive with a simple passive detector and an energye cient thresholding circuit. We describe a prototype that can receive 802.15. 4 frames with a power consumption of 361 μW. Our receiver prototype achieves su cient communication range to integrate with deployed wireless sensor networks (WSNs). We illustrate this integration by pairing the prototype with an 802.15. 4 backscatter transmitter and integrating it with unmodi ed 802.15. 4 sensor nodes running the TSCH and Glossy protocols.

DISCOVERING SEMANTIC REGULARITY IN LEXICAL RESOURCES

We first describe four varieties of thesaurus: (1) Roget-style, produced to help people find synonyms when they are writing; (2) WordNet and EuroWordNet; (3) thesauruses produced (manually) to support information retrieval systems; and (4) thesauruses produced automatically from corpora. We then contrast thesauruses and dictionaries, and present a small experiment in which we look at polysemy in relation to thesaurus structure. It has sometimes been assumed that different dictionary senses for a word that are close in meaning will be near neighbours in the thesaurus. This hypothesis is explored, using as inputs the hierarchical structure of WordNet 1.5 and a mapping between WordNet senses and the senses of another dictionary. The experiment shows that pairs of `lexicographically close' meanings are frequently found in different parts of the hierarchy. These pairs often display regular polysemic relations, i.e. they constitute systematic sense combinations that are valid for more than one word. The second experiment is an attempt to gain more insight into the mechanisms that underlie lexicalized regular polysemy. The hierarchical structure of WordNet is exploited to create a working definition of systematic polysemy and extract regular polysemic patterns at a level of semantic generalization that allows the identification of fine-grained semantic relations between the senses of the words participating in the regular polysemic pattern.
Protein Folding Studies on the Ribosomal Protein S 6 : the Role of Entropy in Nucleation

One of the most challenging tasks remaining in the field of biochemistry is the one of understanding how the information within the amino acid sequence of proteins translates into a unique structure. Solving this problem would lead to endless possibilities for application in the medical and biotechnology industry. Many decades ago scientists realized that the process that facilitates the folding of a polypeptide chain could not be random and happen by chance; there needs to be direction in the folding free energy landscape. This landscape is defined by the thermodynamic factors entropy and enthalpy. The contribution made by enthalpy i.e. the contact energies from intraand intermolecular interactions have been extensively investigated by various mutational studies. The influence of entropy on the other hand, is less well understood. My work focuses on the effect of altering the entropic components of forming the various parts of a known protein scaffold. This is done by genetic engineering in combination with biophysical characterisation and analysis. The results show effects on protein folding rates as well as on the pathway for nucleation and emphasis the ability of the folding landscape to readjust to entropic variations. Proteins are therefore not required to fold along a unique route to their final structure but can do so in several ways. The folding pathways we observe today have hence likely evolved as an adaptation to biological demands.
Securing Iris Recognition System for Access Control Based on Image Processing

: Results of different studies show that iris recognition is a viable, fast, and easy way to authenticate a person's identity and it is the most accurate biometric approach for authentication. The findings are so positive that the prospect of iris prints replacing PINs and other identification methods is much more viable, new studies found that an eye from a dead person would deteriorate too fast to be useful, so no extra precautions have to be taken to be sure the user is a living human being. The big challenge with iris recognition is that an iris scanning security can be cheated by presenting a high resolution still image of an eye to the iris scanner instead of a live eye, also can be cheated by using video frames and 3D model of valid individual. With increasing e-payments nowadays, Un supervised passages with iris scan as a security, a hack-able security can assists criminals and others to access personal and financial information of an individual and in turn, the loss of trust, confidence and respect. This research work propose a more secured iris recognition system which incorporate the ability to detect the aliveness of the individual being scanned by the system for identification to prevent possible spoofing using photographs, videos, and 3D models of a valid user. An algorithm has been developed adapting a proposed improved canny edge detection method, this algorithm validates the user being scanned by three stages which are; Eye blink detection, Background subtraction and correlation, and Straight line border edge detection. All these three stages are performed using digital image processing techniques
Macro, Microscopic and Preliminary Analytical Evaluation of Root and Leaf of Globba Marantina Linn. - An Extrapharmacopoeial Drug of Ayurveda

Globba marantina Linn. , an extra pharmacopoeial plant of Ayurveda, locally known as chhota rasna by tribal people of Orissa, belongs to the family Zingiberaceae. Ethnomedicinally roots and leaves of G. marantina is claimed to be used in the management of asthma, rheumatoid arthritis, cough, cold, snakebite and others. Though used traditionally, no proper scientific evaluation of this plant for its pharmacognostical characters has been reported. Hence, the present study has been performed to establish the root and leaf of the plant for its microscopical and physicochemical characters along with different qualitative tests, as per Ayurvedic Pharmacopoeia of India. Powder microscopy of the root shows ample amount of starch grain, prismatic crystal, lignified fiber, scalariform vessel whereas that of leaf shows monocot type III stomata, ample amount of prismatic crystal, fiber and covering trichome. Surface study shows presence of more number of stomata as well as stomatal index, in lower surface, in comparison to upper surface. Physicochemical parameters shows higher moisture content in leaf sample (9.8060±0.0265% w/w) than the root sample (9.505±0.465% w/w) and water soluble extractive value of both the samples has been found more in comparison to alcohol soluble extractive value. The observed data can be helpful to identify and standardize root and leaf of G. marantina.
Group Status as a Determinant of Organizational Identification After a Takeover: A Social Identity Perspective

This study investigates the relation between the perceived status of an organization after a takeover (i.e. post-merger status) on employees’ identification with this new organization (i.e. their post-merger identification). Respondents were 234 employees of a corrugated board producing company, which had taken over a smaller company eight months before. As hypothesized, post-merger status was positively related to organizational identification among employees of the lower-status pre-merger company, but they were not related among employees of the higher-status company. Also in line with the expectations, post-merger status was positively related to organizational identification among employees who had identified weakly with their pre-merger group, but not among employees who had identified strongly with their pre-merger group.
Protection of a multiterminal DC compact node feeding electric vehicles on electric railway systems, secondary distribution networks, and PV systems

This paper describes a multiterminal DC compact node consisting of voltage-source converters and DC-DC converters as a promising arrangement to feed electric vehicle (EV) charging stations with renewable power sources. This research analyzed the behavior of the node currents under DC faults, and more specically their natural response, which can produce challenging electrical protection requirements. An electrical protection system was thus designed based on the use of protective devices that included protective relays, solid state circuit breakers and hybrid circuit breakers. These protective devices monitor local readings to detect and isolate DC faults as quickly as possible. This highlighted the fact that there are devices, available on the market, that comply with the fast response requirement to prevent damage or destruction of the converters andlter capacitors of the node.
Design of a reputation mechanism for virtual reality: a case for 3D E-Commerce

The interest in 3D technology is growing both from academia and industry, promoting the quick development of 3D e-commerce (i.e. e-commerce systems in 3D virtual environments). In view of this, we propose a reputation mechanism particularly for 3D e-commerce. Supported by 3D technology and virtual reality, it consists of four major components: feedback provision based on human users’ five senses, reputation computation based on feedback, 3D representation of computed reputation, and automatic decision making based on reputation. A user study is conducted to evaluate the necessity and value of our proposed reputation mechanism, confirming that users prefer 3D e-commerce with our proposed reputation mechanism over that with traditional reputation mechanisms. And, our proposed reputation mechanism can effectively ensure user’s trust in the e-commerce system and simultaneously greatly promote user’s trust in other users.

Cyberbullying Detection Task: the EBSI-LIA-UNAM System (ELU) at COLING’18 TRAC-1

The phenomenon of cyberbullying has growing in worrying proportions with the development of social networks. Forums and chat rooms are spaces where serious damage can now be done to others, while the tools for avoiding on-line spills are still limited. This study aims to assess the ability that both classical and state-of-the-art vector space modeling methods provide to well known learning machines to identify aggression levels in social network cyberbullying (i.e. social network posts manually labeled as Overtly Aggressive, Covertly Aggressive and Non-aggressive). To this end, an exploratory stage was performed first in order to find relevant settings to test, i.e. by using training and development samples, we trained multiple learning machines using multiple vector space modeling methods and discarded the less informative configurations. Finally, we selected the two best settings and their voting combination to form three competing systems. These systems were submitted to the competition of the TRACK-1 task of the Workshop on Trolling, Aggression and Cyberbullying. Our voting combination system resulted second place in predicting Aggression levels on a test set of untagged social network posts.
Analysis of Interventions Teachers Use to Manage Learners with Selected Behavior Disorders in Primary Schools in Thika Sub-County, Kiambu County, Kenya.

Identification process is an important element of behavior disorder management in schools. For proper behavior management teachers need to identify learners with behavioral disorders in order to design intervention programs befitting their educational needs. Therefore, the purpose of this study was to analyze the intervention strategies teachers used in managing learners with selected emotional and behavior disorders (EBDs) in primary schools in Madaraka zone. The objectives were; to establish effectiveness of assessment methods teachers used in identifying learners with selected behavior disorders and to explore intervention strategies teachers used in managing learners with selected behavior disorders. The study used descriptive research design which was appropriate since it enabled the researchers to describe the situation as it existed. A questionnaire was used to collect data. Simple random sampling was done to select four schools which participated in the study. Purposive sampling was used to select a sample size of 30 class seven teachers. Data from the research instruments was analyzed and presented descriptively. The study found that the assessment methods teachers used to identify learners with EBDs were not effective and that teachers in selected schools did not use effective intervention strategies to manage behavior for learners with EBDs. The study recommends that in-service training for teachers be done with a view of building capacity in the area of identification processes and that Kenya Institute of Curriculum Development to give guidelines on behavior disorder management. The significance of the study findings is that it could help stakeholders to come up with effective intervention strategies in managing learners with behavior disorders as well as add to the existing literature on learner disorders.

One dimensional Kronig-Penney model with positional disorder: Theory versus experiment

We study the effects of random positional disorder in the transmission of waves in the one-dimensional Kronig-Penny model formed by two alternating dielectric slabs. Numerical simulations and experimental data revealed that the so-called resonance bands survive even for relatively strong disorder and large number of cells, while the nonresonance bands disappear already for weak disorder. For weak disorder we derive an analytical expression for the localization length and relate it to the transmission coefficient for finite samples. The obtained results describe very well the experimental frequency dependence of the transmission in a microwave realization of the model. Our results can be applied both to photonic crystals and semiconductor superlattices.
Design of a variable-stiffness robotic hand using pneumatic soft rubber actuators

In recent years, Japanese society has been ageing, engendering a labor shortage of young workers. Robots are therefore expected to be useful in performing tasks such as day-to-day support for elderly people. In particular, robots that are intended for use in the field of medical care and welfare are expected to be safe when operating in a human environment because they often come into contact with people. Furthermore, robots must perform various tasks such as regrasping, grasping of soft objects, and tasks using frictional force. Given these demands and circumstances, a tendon-driven robot hand with a stiffness changing finger has been developed. The finger surface stiffness can be altered by adjusting the input pressure depending on the task. Additionally, the coefficient of static friction can be altered by changing the surface stiffness merely by adjusting the input air pressure. This report describes the basic structure, driving mechanism, and basic properties of the proposed robot hand.
