Linking the Self-Esteem to Organizational Citizenship Behavior

In this study I analyzed the relationships between organizational citizenship behavior (OCB), and self-esteem personality of banking industry in Indonesia. A survey is conducted by using questionnaires from the previous research. The samples consisted of 500 bank tellers as subordinates and 100 bank head tellers as immediate supervisors from the banking industry provided ratings of OCB. Validity and reliability tests are used to evaluate the questionnaire contents. I employed correlation and regression analyses to analyze the model. The results indicated that self-ratings and supervisor-ratings of OCB were not significantly correlated. Using Multi-Trait Multi-Method matrix, I find strong method effects, indicating that ratings from different sources provide different information. The results also indicated that there were significant differences in the mean ratings across the two sources. The result also indicates self-esteem affect five dimensions of self-ratings of OCB and four dimensions of supervisor-ratings of OCB. Self-esteem doesn’t affect supervisor-ratings of civic virtue. Theoretical and practical implications are discussed.
Capital externalities in two-sector models

We consider a two-sector economy with positive capital externalities and constant social returns. We first show that local indeterminacy does not require external effects from labor but is fundamentaly based on externalities derived from capital in the investment good sector. Second, we show that the external effects in the investment good sector has to be characterized by a low enough amount of capital stock from the consumption good sector. In other words, the existence of multiple equilibria is ruled out if the externalities are too intersectoral.
Effects of BMI on Blood Pressure and Urinary Excretion of Sodium, Chloride and Potassium in Young Paraguayans

Background: Obesity has been associated with an increased risk for coronary disease, type 2 diabetes, hyperlipidemia and mortality. The demographics of Paraguay show that most of the population is of mixed European and Amerindian descent. Most of the studies performed in Hispanics, particularly in the United States fail to identify their country of origin. There is a paucity of data in Paraguay about the relationship between BMI and BP in young adults. Furthermore, there is an increased prevalence of overweight, obesity and hypertension in the country. In this study, we hypothesized that even early increments of BMI are associated with increased blood pressure (BP) readings in young adults in Paraguay. Methods: Cross-sectional study, performed in 72 adult participants, from Asuncion Paraguay. There is no similar study published in this country. BMI, BP readings and urinary excretion of Na, K and Cl were studied. Results: Mean age 25. 2 ± 1.52 years. Mean BMI 24.1 ± 3.66. There was a linear relationship between BMI and SBP, DBP, MAP and urine Na, K and Cl across all levels. A multivariate analysis, adjusting for gender, showed that increased BMI is associated with increased BP readings. A BMI of 23.4 was the best cut-off for a BP equal or higher than 135/85 mmHg (pre- hypertension), (AUC = 0.80). A BMI of 24.2 was the best cut off for a BP equal or higher than 140/90 (AUC = 0.80). After excluding participants with SBP equal or higher than 140 mmHg and DBP equal or higher than 90 mmHg, BMI was still associated with increased SBP and DBP even in normotensive individuals. After excluding obese and overweight patients, we found that even a small increase of BMI was associated with an increase in blood pressure. Conclusions : BMI values of 24.2 and 23.4 were associated with BP of 140/90 and 135/85 respectively. Since the BMI cut-off for obesity was established in different cohorts, we might need to create a more specific set of values for the Paraguayan population, as the values proposed by the American Heart Association are probably rather high for this population. doi:10.4021/wjnu8e
Development of a design for occupational safety and health capability maturity model

Design for occupational safety and health (DfOSH) is growing in prominence in the construction sector. Consequently, designers (as individuals or organisations) are expected to mitigate occupational health and safety risks through design. In order for design firms to effectively do this, they need to have adequate capability in respect of DfOSH. However, there is limited empirical insight regarding DfOSH capability as well as robust mechanisms for ascertaning the DfOSH capability of design firms. Drawing on the capability maturity concept, this study through three iterations of expert focus group discussion presents a preliminary DfOSH capability maturity model. The preliminary model captures DfOSH capability attributes mapped unto five stages of capability maturation. The model is undergoing review and testing by industry experts to ensure its practical utility within industry. It is anticipated that through the testing of the preliminary model, the eventual DfOSH capability maturity model would be beneficial to several industry stakeholders, particularly design firms by way of self-assessing their capability in order to understand the areas of capability deficiency and strength. Clients who appoint design firms could also use the model as part of pre-qualification arrangements in selecting design firms with adequate DfOSH capability.
Multiplierless Refinement Scheme for Interval Calculation of GMM-based Classification

In this work, an efficient refinement scheme is proposed for interval calculation of GMM-based classification. The proposed refinement scheme reduces the circuit area and accelerates the throughput from the original. The proposed scheme consists of scaling for the exponential part and shifting of precalculated values of the fractional part. As a result, the refinement process can be constructed with a multiplierless architecture. An experimental implementation on FPGA shows that the proposed method reduces the circuit area under 52.2% and accelerates the throughput over 117.6% from the architecture with the original interval refinement process.
The Information Content of Revealed Beliefs in Portfolio Holdings

In this paper, we elicit heterogeneous fund manager beliefs on expected stock returns from funds’ portfolio holdings at each quarter-end. Revealed beliefs are extracted by assuming that each fund manager aims to outperform a certain benchmark portfolio by choosing an optimal risk-return tradeoff. We then construct a measure of fund managers’ forecasting ability—the belief accuracy index (BAI)—by correlating a manager’s revealed beliefs on stock returns with the subsequently realized returns. We measure the differences in beliefs between funds with high BAI and all other funds, the belief difference index (BDI). Sorting stocks based on BDI, we find that the annualized return difference between the top and bottom decile is about two to six percent.
Review of emissions from smouldering peat fires and their contribution to regional haze episodes

Smouldering peat fires, the largest fires on Earth in terms of fuel consumption, are reported in six continents and are responsible for regional haze episodes. Haze is the large-scale accumulation of smoke at low altitudes in the atmosphere. It decreases air quality, disrupts transportation and causes health emergencies. Research on peat emissions and haze is modest at best and many key aspects remain poorly understood. Here, we compile an up-to-date inter-study of peat fire emission factors (EFs) found in the literature both from laboratory and from field studies. Tropical peat fires yield larger EFs for the prominent organic compounds than boreal and temperate peat fires, possibly due to the higher fuel carbon content (56.0 vs 44.2%). In contrast, tropical peat fires present slightly lower EFs for particulate matter with diameter ≤2.5 μm (PM2.5) for unknown reasons but are probably related to combustion dynamics. An analysis of the modified combustion efficiency, a parameter widely used for determining the combustion regime of wildfires, shows it is partially misunderstood and highly sensitive to unknown field variables. This is the first review of the literature on smouldering peat emissions. Our integration of the existing literature allows the identification of existing gaps in knowledge and is expected to accelerate progress towards mitigation strategies.
The Image of Orlando as a Tourist Destination: A Reflection through Postcards

Postcards feature multiple interpretations of a single destination including sequential snapshots of change in the destination over time. Given the sustainable role of postcards in promoting destinations, there is a lack of research on postcards within the context of destination image representation. The purpose of this exploratory study is to test an existing conceptual model (Milman, 2010) that analyzed the perception and interpretation of reality as featured in the postcards offered for sale at a major tourist destination. This study applied the model to understand the various postcard image approaches representing Orlando as a tourist destination. In addition, this study investigated some of the constituencies involved in the decision making process associated with the choice of postcards being offered for sale. The authors found that the majority of the postcards offered for sale did not feature a realistic representation of Orlando but a misleading environment or fantasy.
A full-mission data set of H2O and HDO columns from SCIAMACHY 2.3 µm reflectance measurements

Abstract. A new data set of vertical column densities of the water vapour isotopologues H2O and HDO from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument for the whole of the mission period from January 2003 to April 2012 is presented. The data are retrieved from reflectance measurements in the spectral range 2339 to 2383 nm with the Shortwave Infrared CO Retrieval (SICOR) algorithm, ignoring atmospheric light scattering in the measurement simulation. The retrievals are validated with ground-based Fourier transform infrared measurements obtained within the Multi-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water (MUSICA) project. A good agreement for low-altitude stations is found with an average bias of −3.6×1021 for H2O and −1.0×1018 molec cm−2 for HDO. The a posteriori computed δD shows an average bias of −8 ‰, even though polar stations have a larger negative bias. The latter is due to the large amount of sensor noise in SCIAMACHY in combination with low albedo and high solar zenith angles. To demonstrate the benefit of accounting for light scattering in the retrieval, the quality of the data product fitting effective cloud parameters simultaneously with trace gas columns is evaluated in a dedicated case study for measurements round high-altitude stations. Due to a large altitude difference between the satellite ground pixel and the mountain station, clear-sky scenes yield a large bias, resulting in a δD bias of 125 ‰. When selecting scenes with optically thick clouds within 1000 m above or below the station altitude, the bias in a posteriori δD is reduced from 125 to 44 ‰. The insights from the present study will also benefit the analysis of the data from the new Sentinel-5 Precursor mission.
Cryptanalysis of an Untraceable Temporal-Credential-Based Two-Factor Authentication Scheme Using ECC for Wireless Sensor Networks

-Authentication and key agreement scheme is an important mechanism for legal users to access the services of wireless sensor network. However, the design of authentication and key agreement schemes in WSNs is still quite a challenging problem. In this paper, we analyze an untraceable temporal-credential-based two-factor authentication scheme using ECC for WSNs proposed by Jiang et al. in 2016, and point out the scheme can not resist malicious user impersonation attack, sensor node capture attack and suffer from forward security problem, low efficiency problem, no password change phase problem and time synchronization problem.

 Magneto-Optical Spectrum of Group-IV Vacancy Color Centers in Diamond

Group-IV -- Vacancy color centers in diamond are fast emerging qubits that can be harnessed in quantum communication and sensor applications. There is an immediate quest for understanding their magneto-optical properties, in order to select the appropriate qubits for varying needs of particular quantum applications. Here we present results from cutting edge \emph{ab initio} calculations about the charge state stability, zero-phonon-line energies, spin-orbit and electron-phonon couplings for Group-IV -- Vacancy color centers. Based on the analysis of our results, we develop a novel spin Hamiltonian for these qubits which incorporates the interaction of the electron spin and orbit coupled with phonons beyond perturbation theory. Our results are in good agreement with previous data and predict a new defect for qubit applications with thermally initialized ground state spin and long spin coherence time.
Lessons from large-scale conservation networks in Australia

Australia has seen a rapid growth in the establishment of networks of lands managed for connectivity conservation across tenures, at landscape and sub-continental scales. Such networks go under a variety of names, including biosphere reserves, biolinks, wildlife corridors and conservation management networks. Their establishment has varied from state government-led initiatives to those initiated by non-government organizations and interested landholders. We surveyed existing major landscape scale conservation initiatives for successes, failures and future directions and synthesized common themes. These themes included scale, importance of social and economic networks, leadership, governance, funding, conservation planning, the role of protected areas and communication. We discuss the emergence of national policy relating to National Wildlife Corridors in Australia and the relationship of this policy to the long standing commitment to build a comprehensive, adequate and representative National Reserve System. Finally we outline areas for further research for connectivity conservation projects in Australia.
Freeze Dried Chitosan/ Poly-ÃÂµ-Caprolactone and Poly-ÃÂµ-Caprolactone Nanoparticles: Evaluation of their Potential as DNA and Antigen DeliverySystems

Nanoparticles prepared from natural or synthetic polymers have shown potential for antigen and DNA vaccine delivery to mucosal surfaces. The purpose of this research was to prepare chitosan/poly-e-caprolactone (Chitosan/ PCL) nanoparticles and PCL nanoparticles and evaluate their potential as DNA and protein/vaccine delivery systems. Both preparation methods resulted in particles of low cytotoxicity and sizes suggested to be ideal to be taken up by cells (199 ± 62 nm and 165 ± 35 nm, respectively for chitosan/PCL and PCL nanoparticles). However, Chitosan/ PCL nanoparticles offered considerable advantages over PCL nanoparticles as antigen and DNA delivery system. Namely, higher loading efficacies for model antigens studied (myoglobin, BSA, ovalbumin, lactalbumin, α-casein and lysozyme), much higher uptake by A549 cells, great ability to form stable complexes, which protect DNA from nucleases. However, in spite of good DNA and protein loading capabilities, Chitosan/PCL nanoparticles showed much better qualities as a protein delivery system since the rate of cells transfected were not very high.
Analysis of electrocardiographic parameters in the conscious common pheasants (Phasianus colchicus).

Summary The aim of this study was to establish normal electrocardiographic values and patterns in pheasants (Phasianus colchicus). The electrocardiograms were recorded in 24 conscious pheasants from both genders. All electrocardiograms were standardized at 1 mV=20 mm , with a paper speed of 50 mm/sec. Morphological patterns of P, QRS and T deflections were evaluated in the six limb leads (I, II, III, aVR, aVL, aVF). The amplitude and duration of waves and intervals were determined by using lead II. A regular sinus rhythm was observed in all birds. There was no significant difference between male and female pheasants except for amplitudes of P and T waves and duration of T wave. In all leads P waves were mainly positive in both sexes except for lead aVR. The dominant waveforms of the QRS complexes were rS in lead II, III and aVF, and qR in lead aVR and aVL in both sexes. Generally, T waves were positive in lead I, II, III and aVF, and negative in aVL, aVF. The majority of birds showed a slightly elevated ST segment in lead II. Heart rates were 193.5±45.8 and 235.7±59.9 beats per minute and mean electrical axes were -91±10° and -92±18° in male and female birds, respectively. This study provides electrocardiographic data for pheasants, which can be used for clinical purposes.
IPM in the transgenic era: a review of the challenges from emerging pests in Australian cotton systems

Abstract. The Cotton Catchment Communities Cooperative Research Centre began during a period of rapid uptake of Bollgard II® cotton, which contains genes to express two Bt proteins that control the primary pests of cotton in Australia, Helicoverpa armigera and H. punctigera. The dramatic uptake of this technology presumably resulted in strong selection pressure for resistance in Helicoverpa spp. against the Bt proteins. The discovery of higher than expected levels of resistance in both species against one of the proteins in Bollgard II® cotton (Cry2Ab) led to significant re-evaluation of the resistance management plan developed for this technology, which was a core area of research for the Cotton CRC. The uptake of Bollgard II® cotton also led to a substantial decline in pesticide applications against Helicoverpa spp. (from 10–14 to 0–3 applications per season). The low spray environment allowed some pests not controlled by the Bt proteins to emerge as more significant pests, especially sucking species such as Creontiades dilutus and Nezara viridula. A range of other minor pests have also sporadically arisen as problems. Lack of knowledge and experience with these pests created uncertainty and encouraged insecticide use, which threatened to undermine the gains made with Bollgard II® cotton. Here we chronicle the achievements of the Cotton CRC in providing the industry with new knowledge and management strategies for these pests.
On the Mechanism Underlying the Spontaneous Emergence of Barotropic Zonal Jets

AbstractZonal jets are commonly observed to spontaneously emerge in a β-plane channel from a background of turbulence that is sustained in a statistical steady state by homogeneous stochastic excitation and dissipation of vorticity. The mechanism for jet formation is examined in this work within the statistical wave–mean flow interaction framework of stochastic structural stability theory (SSST) that makes predictions for the emergence of zonal jets in β-plane turbulence. Using the coupled dynamical SSST system that governs the joint evolution of the second-order statistics and the mean flow, the structural stability of the spatially homogeneous statistical equilibrium with no mean zonal jets is studied. It is shown that close to the structural stability boundary, the eddy–mean flow dynamics can be split into two competing processes. The first, which is shearing of the eddies by the local shear described by Orr dynamics in a β plane, is shown in the limit of infinitesimal shear to lead to the formation of.
Characterization of C-heterochromatin in four species of Hydrozoa (Cnidaria) by sequence specific fluorochromes Chromomycin A3 and DAPI

Abstract The karyotypes of Pelmatohydra oligactis (Pallas, 1766), Hydra vulgaris Pallas, 1766, Hydra circumcincta Schulze, 1914 (Hydrida, Hydridae) and Pachycordyle kubotai Stepanjants, Timoshkin, Anokhin, Napara, 2000 (Athecata, Clavidae) have been studied for the first time by using the fluorochromes DAPI, and CMA3. In all the species C-heterochromatic regions were stained brightly with DAPI, indicating that constitutive heterochromatin associated with centromeres or NORs is A-T-rich. CMA3 staining showed exceptionally rare G-C-rich clusters associated with NORs.

Optimal Boundary Control of a Timoshenko Beam via Maximum Principle

Boundary control to damp the undesirable vibrations in a Timoshenko beam is considered. For this purpose, controllability and wellposedness of the system are examined. Performance index is defined with regards to the dynamic response of the beam that is defined as a weighted quadratic functional of the displacement and the velocity at terminal time and expenditure of the control energy added as a penalty term. In order to obtain the optimal control function, an adjoint variable satisfying the adjoint equation corresponding to state equation is introduced. The maximum principle is formulated and optimal control function is obtained. Also, by using maximum principle, control problem is transformed into solving a system of partial differential equations including state and adjoint variables with initial, boundary and terminal conditions. MATLAB is used to obtain the solution of the system. Numerical results are given in tables and graphical forms.
Simulative Analysis of Influence of Modulation Techniques on COFDM based Radio over Fiber Transmission

In this paper, Coded Orthogonal Frequency Division Multiplexing (COFDM) based Radio over Fiber (RoF) system is simulated (for different bit rates) for different modulation techniques to observe impact on system parameter (quality factor (Q)). Influence of increasing bit rates has been observed for 2 km long linear multimode fiber. To reduce dispersion due to multimode fiber, convolutional encoder (code rate ½, generator polynomial 1338, 1718) and viterbi hard decision decoding algorithm are chosen for simulative model of COFDM based RoF system. Transmission of 32 sub-carriers with externally modulated continuous wave laser source gave satisfied results for Q values.
