Effects of employee engagement on customer responses: Examining the mediating role of customer engagement

Drawing on emotional contagion theory, this study offers an integrated framework showing the effects of employee engagement (EE) on customer engagement (CE), repeat purchase and word-of-mouth (WOM). The data were collected from 65 employees and 352 customers of 28 retail stores using 2 separate survey instruments. A dyadic data set was created by matching customer data with the employee data corresponding to each store. The findings reveal that two key facets of EE – dedication and absorption – positively influence CE, which eventually influences WOM and repeat purchase. In line with balance theory, CE is found to fully mediate the effects of absorption on WOM and repeat purchase. Furthermore, employee length of service (ELS) is found to moderate the absorption on CE effects. Thus, the findings extend emotional contagion theory and balance theory by providing empirical evidence supporting the differential effects of the facets of EE on CE en route to WOM and repeat purchase.

Lean and green?: evidências empíricas do setor automotivo brasileiro

The aim of this paper is to verify whether the practices of lean manufacturing are positively associated with the adoption of environmental management practices in Brazilian companies in the automotive sector to test the hypothesis that by being lean the business tends to become green. To this purpose, a framework associating these concepts with the research hypothesis was proposed. The data collected from 75 companies were analyzed using Structural Equation Modeling. The main results show that lean manufacturing (LM) is positively associated with environmental management (EM), but the explanation power of LM over EM is considered weak/moderate. In fact, being lean also means being green, but other organizational variables not considered in this study may influence the greening of organizations.
Location accuracy of multistatic radars (TR/sup n/) based on ranging information

In modern ECM and ECCM environment, bistatic and multistatic radar systems have drawn increasing interest in many applications. It is well known that the position of a stationary or moving target can be estimated from measurements of the arrival times, directions of arrival, or Doppler shifts of electromagnetic waves received at various sites. An analysis based on ranging information for the target location accuracy of multistatic radar, with one transmitter and n receivers (TR/sup n/), is presented. The reasonable constellation of the system without knowing the transmitter position parameters is discussed. The geometric dilution of precision (GDOP) of the radar in a constrained space is also given.
A Study on the Change in Energy Performance of the Domestic Building by the Isolation-heat Paint

In this study, it is quantitatively analyzed for thermal Characteristics of isolation-heat paint which has been supplied to a domestic market through experiments and simulations. In the case of experiment using the container box, it shows 8% decrease on cooling energy consumption in a summer season, but shows increase on heating energy consumption. As a result, the analysis has found increase of energy consumption. As a result of holding simulations with meteorological data of domestic major cities, it shows an increase of energy consumption in domestic condition, and it is hard to expect an energy saving from the isolation-heat paint unless greater air-conditioning load.
New application of low cost sensors for continuous CO2 flux measurements

Abstract. Soil CO2 emissions are one of the largest contributions to the global carbon cycle, and a full understanding of processes generating them and how climate change may modify them is needed and still uncertain. Thus, a dense spatial and temporal network of CO2 flux measurements from soil could help reduce uncertainty in the global carbon budgets. In the present study, low cost Air Enquirer kits, including CO2 and environmental parameters sensors, have been designed, built and applied for the first time to design, develop and test a new Steady-State-Through-Flow (SS-TF) chamber for simultaneous measurements of CO2 fluxes in soil and CO2 concentrations in air. Sensor's responses were previously corrected for temperature, relative humidity, illumination and pressure conditions in order to reduce the uncertainty of measured CO2 values and of the following calculated CO2 fluxes. CO2 soil fluxes measured by the proposed SS-TF and by a standard closed Non-Steady-State-Non-Through-Flow (NSS-NTF) chamber were shortly compared. The use of a multi-parametric fitting reduced the total uncertainty of CO2 concentration measurements by 62 % compared with one where only a simple CO2 calibration was applied, and by a 90 % when compared to uncertainty declared by the manufacturer. The new SS-TF system allows continuous measurement of CO2 fluxes and CO2 ambient air with low cost (~1.2 k€), low energy demand (< 5 W) and low maintenance (twice per year due to sensor calibration requirements).
Shape Optimization of Energy Dissipation Devices for Passive Seismic Control of Building Frames

Optimization results are presented for improving energy dissipation capacity of passive seismic control devices under cyclic deformation. The locations and thicknesses of the stiffeners, as well as the aspect ratio, of a shear-type hysteretic steel damper are optimized to improve energy dissipation capacity under static cyclic deformation. A general-purpose finite element software package is used for elastoplastic analysis, and a heuristic optimization algorithm called tabu search is utilized for optimization after discretization of variables into integer values. The objective function is the dissipated energy before the maximum value of equivalent plastic strains among all elements reaches the upper bound under the prescribed loading condition, and constraints on reaction force and moment are incorporated by penalty function approach. The material parameters of the low-yield-point steel are identified through optimization also using tabu search.
Joint estimation of selection intensity and mutation rate under balancing selection with applications to HLA

A composite likelihood method is introduced for jointly estimating the intensity of selection and the rate of mutation, both scaled by the effective population size, when there is balancing selection at a single multi-allelic locus in an isolated population at demographic equilibrium. The performance of the method is tested using simulated data. Average estimated mutation rates and selection intensities are close to the true values but there is considerable variation about the averages. Allowing for both population growth and population subdivision do not result in qualitative differences but the estimated mutation rates and selection intensities do not in general reflect the current effective population size. The method is applied to three class I (HLA-A, HLA-B and HLA-C) and two class II loci (HLA-DRB1 and HLA-DQA1) in the 1000 Genomes populations. Allowing for asymmetric balancing selection has only a slight effect on the results from the symmetric model. Mutations that restore symmetry of the selection model are preferentially retained because of the tendency of natural selection to maximize average fitness. However, slight differences in selective effects result in much longer persistence time of some alleles. Trans-species polymorphism (TSP), which is characteristic of MHC in vertebrates, is more likely when there are small differences in allelic fitness than when complete symmetry is assumed. Therefore, variation in allelic fitness expands the range of parameter values consistent with observations of TSP.
The Effect of Shallow Water on Wave Resistance

1. The general character of experimental results dealing with the effect of shallow water on ship resistance may be stated briefly as follows:—At low velocitie the resistance in shallow water is greater than in deep water, the speed at which the excess is first appreciable varying with the type of vessel. As the speed increases, the excess resistance increases up to a maximum at a certain critical velocity, and then diminishes. With still further increase of speed, the resistance in shallow water ultimately becomes, and remains, less than that in deep water at the same speed. The maximum effect is the more pronounced the shallower the water. For further details and references one may refer to standard treatises, but one quotation may be made in regard to the critical velocity: "This maximum appears to be at about a speed such that a trochoidal wave travelling at this speed in water of the same depth is about times as long as the vessel. It was at one time supposed that the speed for maximum increase in resistance was that of the wave of translation. This, however, holds only for water whose depth is less than 0.2 times the length of the vessel. For greater depths the speed of the wave of translation rapidly becomes greater than the speed of maximum increase of resistance. " In a recent analysis of the data, H. M. Weitbrecht expresses a similar conclusion by stating that for each depth of water there is a critical velocity, but that the critical velocity does not vary as the square root of the corresponding depth. It should be noted that experimental results are for the total resistance. If we assume that this can be separated into three terms, which are simply additive, namely, eddy, frictional, and wave-making resistance, it must be admitted that probably all are affected by limited depth of water. However, the main differences are due to the altered wave-making, and the general explanation is to be found in the fact that there is a limiting velocity, √( gh ), for simple straight-crested waves on water of depth h .
SAR-Satellite for Offshore and Coastal Wind Resource Analysis, with Examples from St. Lawrence Gulf, Canada

This paper illustrates the benefits of using remote sensing methodology as an intermediate step to assess offshore and coastal wind resources. Results are based on an ongoing research to understand wind patterns in the St-Lawrence Gulf. This area combines two advantages for wind power development in Canada: a) very good wind, b) high potential of the large scale integration of wind power with the hydro-wind concept. Advantages and drawbacks of satellite techniques in such a complex environment are reviewed. Our approach of satellite data selection for dominant wind conditions reduces the weakness of Synthetic Aperture Radar (SAR) satellite temporal resolution. Wind fields are extracted from sixteen scenes provided by RADARSAT-1. Results are compared with two main sources: in situ measurements and QuickSCAT scatterometer computations. Among interesting findings, it appears that a relative small sample of scenes can already indicates the best wind sites to be investigated for further analysis. The proposed approach to obtain a global wind map of the gulf and the advantages of such high-resolution wind maps to wind resource assessment are discussed.
Feelings first? Sex differences in affective and cognitive processes in emotion recognition

The recognition of emotional expressions is important for social understanding and interaction, but findings on the relationship between emotion recognition, empathy, and theory of mind, as well as sex differences in these relationships, have been inconsistent. This may reflect the relative involvement of affective and cognitive processes at different stages of emotion recognition and in different experimental paradigms. In this study, images of faces were morphed from neutral to full expression of five basic emotions (anger, disgust, fear, happiness, and sadness), which participants were asked to identify as quickly and accurately as possible. Accuracy and response times from healthy males (n = 46) and females (n = 43) were analysed in relation to self-reported empathy (Empathy Quotient; EQ) and mentalising/theory of mind (Reading the Mind in the Eyes Test). Females were faster and more accurate than males in recognising dynamic emotions. Linear mixed-effects modelling showed that response times were inversely related to the emotional empathy subscale of the EQ, but this was accounted for by a female advantage on both measures. Accuracy was unrelated to EQ scores but was predicted independently by sex and Eyes Test scores. These findings suggest that rapid processing of dynamic emotional expressions is strongly influenced by sex, which may reflect the greater involvement of affective processes at earlier stages of emotion recognition.
Role of MXenes/Polyaniline Nanocomposites in Fabricating Innovative Supercapacitor Technology

Versatile and exclusive electronic, optical, physicochemical, electrochemical and mechanical features of both conducting polymers and MXenes have stimulated global scientists to take serious impetuses in designing innovative high-performance energy storage systems with these materials, for resolving the growing needs for auto-powering mechanically flexible and wearable electronics for all essential technological fields. However, both the materials have experienced some serious practical limitations, which have driven the scientific community to look for necessary modifications in the form of MXenes/PANI nanocomposites with suitable compositions that would essentially restore their representative characteristics but successfully suppress their functional drawbacks concurrently and considerably. Accordingly, in the present overview, the different strategies of fabrication of MXenes/PANI nanocomposites for advanced supercapacitors with special reference to the necessary morphological modifications brought about by synthetic improvisations that resulted in superior capacitive, electronic charge transport as well as structural properties have also been recognized and compared. Such analysis would purposefully assist in adjusting the integral mechanical and electrochemical responses for scheming smarter and highly flexible microelectronics soon.
ROLE OF SOCIAL MEDIA ON COMMUNITY MOBILIZATION

Purpose: Globally, effective political engagement requires candid communication between the government and its citizens. More so, citizens have the right to express how they need to be governed. On government’s part, the need to develop trust among the public should be paramount. Government should always inform citizens what it is continually doing. Furthermore, public domains ought to reflect integrity and transparency. Such is achievable through communication on many of its activities. In the recent past, government utilized traditional media to convey information to the public. Popular avenues used included television, newspapers and radio. The general objective of the study was to establish the role of social media on community mobilization Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps. Findings: The study found out that the adoption of social media as a means of communication between the government official’s community members has an enormous impact on community mobilization for security matters and other issues. Social media platforms have enabled quick sharing of information on Barraza. The social media platforms enable this community mobilization in a cost-efficient manner Although social media use offers enormous value in public relations, there is little evidence that social networking sites are used to inform and involve governmental public opinion agencies such as the public sector. Recommendations: The study recommends that public administrators to embrace social media platforms such as Facebook, Twitter and WhatsApp due to their responsiveness and lower costs in interacting with the public administrators and amongst themselves. The respective government agencies should create awareness among the public on the importance of using digital platforms to pass or receive information on security issues
ZARP: An automated workflow for processing of RNA-seq data

RNA sequencing (RNA-seq) is a crucial technique for many scientific studies and multiple models, and software packages have been developed for the processing and analysis of such data. Given the plethora of available tools, choosing the most appropriate ones is a time-consuming process that requires an in-depth understanding of the data, as well as of the principles and parameters of each tool. In addition, packages designed for individual tasks are developed in different programming languages and have dependencies of various degrees of complexity, which renders their installation and execution challenging for users with limited computational expertise. The use of workflow languages and execution engines with support for virtualization and encapsulation options such as containers and Conda environments facilitates these tasks considerably. Computational workflows defined in those languages can be reliably shared with the scientific community, enhancing reusability, while improving reproducibility of results by making individual analysis steps more transparent. Here we present ZARP, a general purpose RNA-seq analysis workflow which builds on state-of-the-art software in the field to facilitate the analysis of RNA-seq data sets. ZARP is developed in the Snakemake workflow language using best software development practices. It can run locally or in a cluster environment, generating extensive reports not only of the data but also of the options utilized. It is built using modern technologies with the ultimate goal to reduce the hands-on time for bioinformaticians and non-expert users. ZARP is available under a permissive Open Source license and open to contributions by the scientific community. Contact mihaela.zavolan@unibas.ch, alexander.kanitz@unibas.ch
Array of coupled phase-locked oscillators at 160 GHz

A ten-channel millimeter-wave heterodyne phase measurement system is currently under construction. This system will be used for electron density measurement at the plasma experiment W7-AS. The main features are: (1) twofold usage of each 160-GHz oscillator to excite both the transmitting signal to the plasma and the local oscillator (LO) signal for downconversion and (2) the phase-locked loops (PLL's) of each oscillator are coupled in a chain. The authors describe the millimeter-wave part and the digital PLL circuits of that system. Test results of the first three channels, which are already running in the laboratory, are presented.
Implementation of ADALINE on a DSP for real-time measurement of current harmonics

The objective of this paper is to implement an ADAptive LINear Element (ADALINE) for real-time measurement of harmonics in load current waveform using a digital signal processor (DSP). Harmonics cause many ill effects and reduce power quality. Harmonics are being measured by fast fourier transform (FFT) algorithm executed on a microprocessor or DSP system. The FFT algorithm implemented as per international electrotechnical commission (IEC) 61000-4-7 requires 1,000 samples to be acquired from ten cycles for a 50 Hz-system. This paper presents the results of implementation of ADALINE algorithm on a DSP for measurement of harmonics in real-time. The proposed method requires acquisition of only 100 samples from one cycle of the load current. Thus the acquisition time in the proposed implementation reduces to 20 ms from 200 ms. The results obtained using the proposed method are found to be close to that of a standard FFT based power quality analyser.
The importance and allocation of risks in Indonesian construction projects

To effectively manage risks in construction projects, it is crucial to correctly identify important risks and properly allocate them to the contractual parties. Understanding the perceptions of construction contractors and owners on the importance and allocation of risks in Indonesian construction projects is an important step in this process. A questionnaire survey was conducted and 27 construction risks were identified and evaluated. Significant differences in perceptions are encountered for the importance of several types of risk, especially those related to the contractor's competence. The respondents had different expectations toward the allocation of a number of risks, and at present, many risks are unclearly apportioned to the contracting parties.
N-Class Fire Resistant Divisions in U.S. Naval Ships

The U.S. Navy has now developed an N-Class division system to classify fire resistant boundaries in accordance with MIL-STD-3020, fire resistance on U.S. naval surface ships. The N-Class division is analogous to the commercial International Maritime Organization (IMO) system (e.g., A-Class) division. The key difference is that N-Class divisions are designed to have satisfactory fire resistance when exposed to hydrocarbon pool fire (UL 1709 fire exposure) following a shock event. In addition, N-Class is applicable to fire resistant divisions constructed from polymer composites structures when they meet the requirements of DDS-078-1. MIL-STD-3020 requires a hydrocarbon pool fire exposure (UL-1709 fire exposure) which provides a minimum average total heat flux of 188 kW per square meter (kW/m2) (60,000 British thermal unit per square foot/hour (Btu/ft2∣h)) within the first 5 min of the test exposure. At all times after 5 min, the average temperature within the furnace shall be maintained at a minimum of 1038 °C (1900 °F) and a maximum of 1149 °C (2100 °F) for the duration of the test. These fire conditions simulate a post-flashover fire scenario for shipboard applications. Performance is defined as the time period during which assemblies will continue to perform their intended function when subjected to fire exposure. The minimum duration of fire exposure is 30 min. Shock testing prior to fire resistance test is performed to ensure that fire resistance of divisions, with fire insulation, penetrations, and associated attachment methods, is not degraded in a combat environment. Shock test specimen size of 1219 by 3048 mm (4 by 10 ft) was selected to reduce the cost of shipping a full size fire test specimen of 3048 by 3048 mm (10 by 10 ft) or greater to the fire test laboratory. A full scale fire resistance test is still required for qualification purposes after successful completion of the shock test prior to fire resistance test. MIL-STD-3020 also permits AN-Class fire resistant divisions when fire threat is from common combustibles (Class A) and where liquid flammable (Class B) fire threat is non-existent. AN-Class divisions are those divisions formed by bulkheads and decks that are designed to protect against structural failure and prevent the passage of flame or hot gases when exposed to IMO Resolution A.754(18) fire exposure after shock testing. For all AN-Class divisions, including those with penetrations, the fire test duration is a minimum of 60 min. This paper will discuss fire resistance test results conducted using steel, aluminum, and composite substrates.
