Communication-Efficient and Fine-Grained Forward-Secure Asynchronous Messaging

In recent years, motivated by the revelation of long-term and widespread surveillance of personal communications, extensive efforts have been putting into store-and-forward asynchronous messaging systems (e.g., email and SMS) for providing critical security guarantees. Of particular interest among them is forward security, which makes past messages remain secure in the event that the secret key gets exposed. Traditional forward-secure public key encryption can provide forward security for asynchronous scenarios, but it is not flexible enough for instant messaging systems. This is mainly because that, after updating his/her secret key, the user totally loses the decryption capacity of ciphertexts that have not been received. In this paper, to achieve practical forward-security of asynchronous messaging systems, we investigate the construction of a new primitive named forward-secure puncturable encryption (FSPE) that captures fine-grained forward security. Namely, the user can maintain the decryption capacity of those encrypted messages that have not been received yet. Meanwhile, even if the secret key is disclosed, those received messages can still remain secure. Specifically, we propose a communication-efficient FSPE scheme for achieving fine-grained forward-secure asynchronous messaging. Moreover, to improve the efficiency of asynchronous messaging built upon FSPE, we extend it to support outsourced decryption. We also implement the proposed scheme and evaluate a proof-of-concept of main algorithms, so as to increase confidence on its correctness and practicability.
Improved supersingularity testing of elliptic curves

In protocols of isogeny-based cryptosystems, we send data of elliptic curves. Then it is necessary to identify supersingularity of the elliptic curves to guarantee the correctness of protocol. Among deterministic algorithms for the purpose, Sutherland proposed an eﬃcient algorithm that utilizes sequences of 2-isogenies computed by using modular polynomials. In this paper, we improve the eﬃciency of the algorithm by using some properties of x -coordinates of 2-torsion points instead of modular polynomials. Our experimental result shows that our algorithm succeeded in reducing the computation time by 14 to 32 percent compared to Sutherland’s algorithm

The Effects of Labeling on Environmental Self-identity

Labeling refers to the behavior that a person uses specific words to label and tends to describe according to the label. For example, when labeled as “environmentally-conscious”, one will enhance his/her pro-environmental behaviors. Thus that will strengthen his/her environmental self-identity, which, in turn, will promote pro-environmental behaviors. This paper looks into the effects of four labels on pro-environmental behaviors. The study into elephant protection found that negative labels can significantly encourage elephant protection and discourage the consumption of elephant-related products. This research will provide a policy tool for environmental organizations and relevant governmental departments.
Electrochemistry of Hemoglobin-Ionic Liquid-Graphene-SnO2 Nanosheet Composite Modified Electrode and Electrocatalysis

A composite that consisted of SnO2 nanosheet, graphene (GR), ionic liquid (IL) and hemoglobin (Hb) was modified on carbon ionic liquid electrode (CILE). By using Nafion film for fixing, the modified electrode was named as Nafion/Hb-IL-GR-SnO2/CILE. Spectroscopic data indicated that Hb molecules kept native structure within the composite. Cyclic voltammetric data gave a pair of well-defined redox peak in 0.1 mol L -1 phosphate buffer solution, proving that direct electron transfer of Hb in the composite with CILE was realized. The result was due to synergistic effects of the materials used, which fastened the electron transfer rate. Nafion/Hb-IL-GR-SnO2/CILE had excellent electrocatalytic ability to the reduction of trichloroacetic acid in a linear concentration range from 2.0 to 11.0 mmol L -1
Hydrologic Monitoring Plan of the Brazilian Water Producer/PCJ Project

Both Ecosystem-based Adaptation (EbA) and Payment for Ecosystem Services (PES) have a wide range of strategies that include different economic instruments for nature conservation. Although the generation and maintenance of payment for hydrologic ecosystem services (Water-PES) is expanding in Brazil, there are difficulties in the implementation of projects. Due to the complexity and non-linearity of the hydrological processes, also affecting both EbA and Water-PES goals, monitoring quali-quantitative aspects of streams have been here addressed as a useful management tool. This study presents the Hydrological Monitoring Plan (HMP) of the Water Producer/PCJ project, operating between 2009-2014, in order to: 1) evaluate the impact of project actions under water quali-quantitative aspects; and 2) promote the incorporation of HMP’s elements in water resources management. HMP of the Water Producer/PCJ project has been implemented following the conditions for efficiency (baseline, long-term scale compatible with the actions of the project, in the experimental and reference watersheds). In addition, HMP is being implemented from upstream to downstream in catchments with areas ranging from 17 to 130 km2. This proposal favors the quantification and valuation of hydrologic services that could be assessed by ecohydrologic monitoring and modeling. Thus, we look forward to the consolidation of the Brazilian information system of water resources, the reduction of modeling uncertainties and integrated assessment of the consequences of land-use/land-cover change that strongly impact goals of EbA and Water-PES initiatives.

Reversible Three-Electron Redox Reaction of Mo3+/Mo6+ for Rechargeable Lithium Batteries

To increase the energy density of lithium batteries, the development of high-capacity positive electrode materials is essential. Herein, we propose the use of a three-electron redox reaction of Mo3+/Mo6+ for a new series of high-capacity lithium insertion materials. In this study, a binary system of LiMoO2–Li3NbO4 is targeted, and nanosize and metastable Li9/7Nb2/7Mo3/7O2 is successfully prepared by a mechanical milling process. The sample delivers a large reversible capacity of ∼280 mAh g–1 in a Li cell with good capacity retention. On the basis of these results, the future possibility of high-capacity electrode materials with a three-electron Mo3+/Mo6+ redox reaction is discussed.
Core–shell nano-structured carbon composites based on tannic acid for lithium-ion batteries

Core–shell nano-structured carbon composites have been used as electrode materials in lithium-ion batteries (LIBs) with increasing attention. The large volume swing during lithiation/delithiation processes and poor electronic conductivity are two key issues in the newly-proposed electrode materials, which severely limit their practical applications in LIBs. In order to solve these problems, we report a facile and versatile method to prepare core–shell nano-structured carbon composites using low cost and widely available tannic acid as the carbon source. The carbon layers with controlled thicknesses of 6–12 nm and 1–3 nm were coated on the surface of Si and TiO2 nanoparticles, respectively. Due to the carbon layers, both the Si@C and TiO2@C nanocomposites used as anode materials in LIBs showed excellent electrochemical performances including good cycling stability and high rate capability. We believe that this method may be applicable to various carbon-coating nanocomposites.
Okul Öncesi Öğretmen Adaylarının Aile Katılımına Yönelik Tutumları ile Aile Katılımına Yönelik Bariyer Algıları Arasındaki İlişki

Purpose: The present study aimed to examine the relationship between pre-service pre-school teachers’ attitudes towards family participation and their barrier perception towards the participation. More specially, this study attempted to answer the following questions: (a) Are pre-service teachers’ attitudes towards family participation and barrier perceptions differ according to their demographic characteristics (parents’ education status, having taken any lessons for family participation, receiving pre-school education)? , (b) Is there a significant relationship between pre-service teachers’ attitudes towards family participation and their barrier perception towards family participation? Method and Materials: This study is a descriptive research conducted in relational survey model. In the present study, the relationship pre-school pre-service teachers’ attitudes towards family participation and family participation barrier perceptions was examined. 284 pre-service teachers attending the Preschool Teaching program participated in the study. In the study, the Personal Information Form, Attitude Scale Towards Family Participation, and the Family Participation Barrier Perception Form were used. Results: According to the first finding obtained from the study, there is no significant difference in the attitudes towards family participation and barrier perceptions of family participation of pre-service teachers who have taken family participation course in undergraduate education and those who have not yet taken family participation course. Teacher candidates’ attitudes towards family participation and barrier perceptions do not show a significant difference according to the education level of the mother. While the father’s education level does not make a significant difference in the barrier perceptions of teacher candidates towards family participation, it does create a significant difference in attitudes towards family participation. According to another finding obtained from the study, the attitudes of teacher candidates who have received pre-school education towards family participation are significantly higher than those who have not received preschool education. As the second conclusion, as the positive attitude towards family participation increased, the barrier perception towards family participation decreased; similarly, as the barrier perception towards family participation increased, the positive attitude towards family participation decreased.
A Hybrid Approach for Performance and Energy-Based Cost Prediction in Clouds

: With the striking rise in penetration of Cloud Computing, energy consumption is considered as one of the key cost factors that need to be man-aged within cloud providers’ infrastructures. Subsequently, recent approaches and strategies based on reactive and proactive methods have been developed for managing cloud computing resources, where the energy consumption and the operational costs are minimized. However, to make better cost decisions in these strategies, the performance and energy awareness should be supported at both Physical Machine (PM) and Virtual Machine (VM) levels. Therefore, in this paper, a novel hybrid approach is proposed, which jointly considered the prediction of performance variation, energy consumption and cost of heterogeneous VMs. This approach aims to integrate auto-scaling with live migration as well as maintain the expected level of service performance, in which the power consumption and resource usage are utilized for estimating the VMs’ total cost. Specifically, the service performance variation is handled by detecting the underloaded and overloaded PMs; thereby, the decision(s) is made in a cost-effective manner. Detailed testbed evaluation demonstrates that the proposed approach not only predicts the VMs workload and consumption of power but also estimates the overall cost of live migration and auto-scaling during service operation, with a high prediction accuracy on the basis of historical workload patterns.
Design of reheating system for graphene film of lithium battery in low temperature environment

Because of its advantages of small pollution, long life, high energy density and low self discharge rate, lithium-ion batteries are widely used in the fields of robots and electric vehicles. However, the low temperature conditions have a significant impact on the battery capacity and cycle life of lithium-ion batteries, which greatly limits the promotion and application of lithium-ion batteries to the high latitude and cold areas in the north, and becomes a constraint The key technology of robot and electric vehicle development. In view of the application problems faced by lithium-ion batteries at low temperature, extensive research and technical research have been carried out, and a technical scheme of low-temperature lithium-ion battery's rewarming, which combines the external graphene rewarming PET film technology, internal discharge circuit heating and polyurethane foam insulation design, has been put forward, effectively solving the technical bottleneck.
A Proposal for Global Situational Theory

In this editorial, I make the case for situational theory. Business communication is now a global phenomenon where individuals speaking different first languages, coming from different national cultures, and having to deal with diverse and complex situations interact with each other. Universal theory or the one best way approach is no longer appropriate in this increasingly diverse and complex global communication environment. It should be replaced by global situational theory. The present state-of-affairs shows the coexistence of universal theory coupled with situational theories describing US/Western and Asian/Eastern management and communication systems. Inconsistencies and contradictions exit in the theory. I propose a framework to guide the development of global situational theory that integrates universal, US/Western, and Asian/Eastern theory. My proposal has four interrelated components: (1) organize theory and research into macro situational categories: industries (domestic, international, global, multi-domestic, and transnational) and organizational configurations (machine, professional, entrepreneurial, innovative, and multi-divisional) to reflect global and universal macro situations; (2) analyze and determine whether and what features of national culture influenced systems will be maintained, drop out, or merge into new features in the macro situations; (3) create micro situations composed of national culture influenced management and communication systems in industries and configurations to guide research and theory building; and (4) reclassify universal theory and past successful but discarded practices into macro situational categories. I describe how these four components that can be combined to develop situational theories that are appropriate to the widely different situations that exist in the present and future business communication environments. These theories can form the framework to guide research, theory development, and business practice. Industries and Configurations
The effects of perceived competence and self-controlled goal setting on motor learning

Purpose. On the basis of the assumptions that motor learning involves a process in which the learner gains competence on a task, and perceived competence is closely related to the achievement of a goal and the perception of control, this study investigated the effects of perceived competence and self-controlled goal setting on motor learning. Methods. Sixty right-handed volunteers, both male (n = 28) and female (n = 32), with an average age of 26.35 years (± 6.29) took part in this experiment. the motor learning task was the field tennis forehand stroke. the experiment involved 2 phases: acquisition and transfer. the acquisition phase consisted of 180 trials performed across 3 days. the transfer test comprised 10 trials under a modified ball flight velocity condition. the participants were divided into 3 groups depending on the level of perceived competence (high, moderate, and low). Furthermore, each group was subdivided into choice (self-controlled goal setting) and yoked groups. Results. Performance of the high perceived competence group was superior to that in the low perceived competence group; there was no significant increase in the perception of competence in both groups. Learning was similar for self-controlled and yoked groups. Conclusions. the findings allow us to conclude that the higher the perceived competence, the better the performance in the acquisition and transfer. Moreover, the control on goal setting did not provide an additional positive effect on motor skill learning in individuals of different levels of perceived competence.
An Optimized Data Fusion Paradigm for WSN Based on Neural Networks

: Wireless sensor networks (WSNs) have gotten a lot of attention as useful tools for gathering data. The energy problem has been a fundamental constraint and challenge faced by many WSN applications due to the size and cost constraints of the sensor nodes. This paper proposed a data fusion model based on the back propagation neural network (BPNN) model to address the problem of a large number of invalid or redundant data. Using three layered-based BPNNs and a TEEN threshold, the proposed model describes the cluster structure and filters out unnecessary details. During the information transmission process, the neural network’s output function is used to deal with a large amount of sensing data, where the feature value of sensing data is extracted and transmitted to the sink node. In terms of life cycle, data traffic, and network use, simulation results show that the proposed data fusion model outperforms the traditional TEEN protocol. As a result, the proposed scheme increases the life cycle of the network thereby lowering energy usage and traffic.
Indicators of exhaustion and stress markers in endurance horses

Intensive physical activity leads to a variety of changes and adaptations, which may influence health and racing performance of horses. Key changes in the body occur due to the loss of fluids and electrolytes, primarily through sweating and ventilation, leading to accumulation of harmful metabolic products and consequential cell damage. These changes lead to the onset of symptoms of fatigue, exhaustion and stress, with prolonged delayed reaction that can be monitored in post exercising period (10, 30). Intensity of fatigue, exhaustion and stress depend on the amount of workload, environmental conditions under which the work is done and level of fitness and soundness of the horse. Beside the physical fatigue and accumulation of harmful metabolites, external conditions – i.e. temperature, humidity, wind, altitude and track quality (hard, heavy, slippery, deep, steep) – have a significant role in building fatigue due to the large distances that endurance horses have to cover. Sweating, especially during hot, humid days can lead to dehydration and electrolyte disbalance and due to the development of metabolic syndrome and disqualification, and in some cases, a horse can even collapse before reaching the finish (3, 4, 17). Subclinical injuries of locomotory apparatus can lead to lameness in late phases of the competition, while incorrect shoeing, respiratory and cardiovascular problems, also influence the outcome of the race and horses with any of these conditions usually find it harder to tolerate ambiental conditions (3, 4, 19). Physical activity can lead to visible fatigue, depression, difficult breathing, excessive sweating and/or lameness. Physical activity also induces changes of several hematological and biochemical parameters. Inadequate muscle perfusion can lead to anaerobic glucose metabolism and the building up of acid metabolites, predominantly lactic acid, lowering pH and the depletion of buffering capacities of body fluids (5, 21, 23). Horses loose large amounts of fluids through sweating, which causes an increase in total protein and albumin concentration, development of hemoconcentration and an increase in packed cell Indicators of exhaustion and stress markers in endurance horses
Preparation and Properties of Sustainable Concrete Using Activated Sludge of Industrial By-Products

Industrial sludge byproducts contain CaO, SiO2, Al2O3, etc. When industrial sludge is used in ready-mixed concrete, the performance of the concrete can be enhanced due to the hydration reaction. In the present study, activated sludge was used to prepare ready-mixed concrete, and its durability performance was evaluated. Once the activated sludge was used, the durability of the concrete improved. Therefore, it is suggested that activated sludge can be used in concrete mix as an admixture.
Damage reduction countermeasures for short span bridges focusing on restorability of structural joints

: Lying on one of the world’s most active seismic faults, Japan faces the continuous threat of natural disasters. The earthquake that struck east Japan on 11 March 2011, and the devastating tsunami, raised many very serious questions about this country’s land and its disaster prevention and disaster reduction strategies for resilience. Disaster-related losses cause short-as well as long-term adverse effects on economy, society, health, culture and the environment. In Japan, the events of 11 March 2011 highlighted the need for the related government agencies, municipalities, research organisations and universities to work together in formulating and implementing a holistic and comprehensive policy approach for damage reduction countermeasures. In this paper, damage reduction countermeasures for short span bridges are presented focusing on the restorability of structural joints, with a view to earthquakes, tsunamis, floods, and deterioration.
