The Influence of Organizational Support Perception on Grassroots Civil Servants’Courage to Shoulder Responsibilities: An Empirical Study Based on the Survey Data of the Pearl River Delta Region

Based on a questionnaire survey of 236 grass-roots civil servants in the Pearl River Delta region, the relationship between organizational support perception and grassroots civil servants’ courage to shoulder responsibilities has been analyzed. The influence of organizational support perception's four dimensions on courage to take responsibilities has tendencies going from strong to weak, which are followed by employee value identification, work assistance support, superior support and employee benefits support. Introduction Based on the survey of some government units in the Pearl River Delta region,this paper discusses the relationship between organizational support perception and courage to shoulder responsibilities, in order to discover and construct the organizational environment and individual growth laws for grassroots civil servants to take up responsibilities actively. With the points of Griffin [1] , Neal, Long Jiangyan, Parker and Collins [2] absorbed, the Courage to Shoulder Resposibilities is divided into three dimensions in this paper: proactive work behavior, individual-organization matching behavior and proactive strategic behavior. From the perspective of the basic elements proposed by Jing Huaibin, organizational support perception consists of four dimensions: work assistance support, superior support, employee benefits support and employee value identification. Eisenberger, Xiao Mingzheng and other scholars believed that proactive behavior is closely related to enviroment and situation [3] . So, it’s believed that organizational support perception has a certain connection with courage to shoulder responsibilities. We advanced Hypothese1 that organizational support perception has significantly positive effect on grass roots civil servants’ courage to shoulder responsibilities, which includes 12 sub-hypotheses (Table 1). For example, H1a: work assistance support has significantly positive effect on proactive work behavior; H1j: superior support has significantly positive effect on proactive strategic behavior, and so on.

Measuring individual frictional costs and willingness-to-pay via name-your-own-price mechanisms

Name-your-own-price is a pricing mechanism where the buyer instead of the seller determines the price, because the buyer makes a bid at a certain price, which the seller can either accept or reject. Based on consumers’ bidding behavior at a name-your-own-price seller, we develop and empirically test a model to simultaneously estimate individual willingness-to-pay (WTP) and frictional costs. Further, we compare analytically and empirically bidding behavior and profit implications of the single bid model to those of the repeated bidding model. Thereby, we derive closed form solutions for the optimal bids which describe the influence of willingness-to-pay and frictional costs on consumer's bidding behavior. In addition, we develop a procedure for estimating empirically willingness-to-pay and frictional costs for individual consumers. Finally, we discuss the findings and limitations as well as their implications for providers of name-your-own-price mechanisms.

Arrays with square and hexagonal lattices of circular holes are compared. We relate this model to experimental data.
Clinical, Radiological and Pathological Co-Relation Of Mandibular Involvement In Cancers Of Oral Cavity

Introduction: In Head and neck squamous cell carcinoma (HNSCC), the clinical assessment of mandibular involvement is often inaccurate and unreliable. Involvement of mandible, upstage the disease to stage IV. Investigations like orthopantogram, computed tomography (CT), magnetic resonance imaging (MRI), bone scintigraphy etc have been evaluated by different authors for involvement of mandible with wide variation in results. This has prompted us to correlate clinically, radiological, and pathological to formulate the appropriate protocol for evaluation of mandibular involvement. Materials And Methods: It is a prospective and a retrospective study. In prospective part, all patients with clinical and radiological confirmation of mandibular involvement were undergone mandibulectomy. The histologic findings of mandibular bone involvement were then compared with the radiographic findings, along with tumor location, stage, and grade. For retrospective study, the medical records of patients, who had under gone mandibulectomy as a part of treatment of oral cavity cancers were analyzed and correlated. Results: In the present study, the bone involvement was found in 69% clinically, 40.5% by Orthopantogram, 39.6% by CT scan and 54% on MRI scan. The histological confirmation of bone involvement was evaluated in all the above cases. It was found that 22% of clinically positive, 46% of OPG positive patients, 52% of CT scan positive and 46% of MRI positive had invasion Conclusion: There is no single modality of investigation which appears to have high specificity and sensitivity. Combination of different modalities increases the both sensitivity and specificity. In our study clinical examination along with high resolution CT scan has the acceptable sensitivity and specificity which may be applied for better results.

Connectivity Assessment and Training: A Partial Directed Coherence Approach

ABSTRACT Background. The multivariate autoregressive (MVAR) method to generate a linear model of multichannel signal processes has been employed in many fields but not applied to the assessment of quantitative electroencephalographic (QEEG) connectivity neurofeedback. A measure known as Partial Directed Coherence (PDC) derived in the MVAR framework can offer insensitivity to volume conduction and ability to provide information relating to the direction of information flow between electrode locations, as a function of frequency during QEEG assessment and neurofeedback. Method. This article outlines a variety of reasons why PDC and other related metrics could play a more fundamental role in elucidating the causal relationships underlying EEG connectivity than can be provided though a multivariate analysis of coherence alone. Results. Real-time PDC neurofeedback implementation issues are discussed, technical challenges are outlined, and research questions are proposed. Conclusion. MVAR-based methods are an a.
The impact of the promotion of row planting on farmers’ teff yields in Ethiopia

Adoption of yield increasing technologies is seen as a key driver to increase agricultural production in Sub-Saharan Africa. There is, however, a lack of empirical evidence on the impact of programs aiming to scale-up the adoption of improved technologies from research settings to the farm level. To fill this gap, this paper assesses the impact of the promotion of a new agricultural technology, i.e. row planting at reduced seed rate, on farmers’ teff yields in Ethiopia. The results of a randomized control trial show that the program to scale-up row planting on average has a positive effect on teff yield. Depending on the measure of yield used, we find increases between 2 percent—but not statistically significant—and 17 percent. These findings are in contrast with larger yield increases found on village demonstration plots and in more controlled settings, as well as with the yield increase expected by teff farmers. The differences seemingly are linked to problems in implementation of the program and of its recommendations, methodological issues, and likely over-optimism on the potential of row planting in real farm settings.
Cognitive dysfunction progression in schizophrenia - relation to functional and clinical outcome

Summary aim. In the present work we tested the hypothesis of cognitive function disorder progression in schizophrenia. Methods. c urrent cognitive, clinical and functional status of 34 chronic schizophrenic patients (13 males, 21 females), with mean 31 year-long duration of illness, was assessed. For neuropsychological assess- ment we used Wc ST, TMT, Stroop Test and Verbal Fluency Test. Results were compared with performance of 30 age, sex and educational level matched healthy controls and 20 first-episode subjects investigated before starting the first pharmacological treatment. results . c ompared to first-episode drug-free patients, individuals with chronic schizophrenia performed worse on tests measuring psychomotor speed and shifting abilities (TMT A and B) and cognitive flexibility (more perse- verative errors in the WcST). They also had more perseverations in letter and category Verbal Fluency Test. discussion . These results are in accordance with data from studies indicating rapid cognitive dysfunction progression in later stages of schizophrenia. Obtained differences cannot be explained only in terms of age differences. In group of chronic schizophrenic patients, worse cognitive abilities were related to poor functional outcome in individuals with longer duration of illness. Conclusion . The results suggest that cognitive dysfunctions seem to have progressive character in the course of illness and are associated with present clinical and functional outcome.
Modified Ground Circle Like-Slot Antenna with Dual Band- Notched Characteristics for Super UWB Applications

─ In this paper, a compact modified ground slot antenna is proposed. This antenna is designed for super ultra-wideband (UWB) applications. To reduce the interference effect on the WLAN and WiMAX systems, it comes up with dual band notched characteristics. In the antenna geometry, a pair of L-shaped stubs connected to the fork-shaped patch is employed to introduce single band-notched characteristics in 5.15-5.825 GHz for WLAN system. This feature also causes that the middle frequency of the band is highly improved. Moreover, a T-shaped stub is added to the center of the fork-shaped patch to generate the frequency band stop performance in 3.3-3.8 GHz for WiMAX system. Furthermore, we propose a modified ground plane including a pair of inverted T-shaped slits, cut from the ground plane, to improve the bandwidth to 164%. The simulation and measurement results indicate a very wide impedance bandwidth from 2.5 up to 23 GHz, with pre-designed dual band notched properties, for the proposed antenna. This slot antenna with abovementioned frequency bandwidth has a compact size of 24 25 mm2, and therefore is suitable for many UWB applications. Index Terms ─ Circle-like slot, dual band-notched characteristics, L-shaped and T-shaped stubs, modified ground plane, T-shaped slits.

Benthic Recovery after the Cessation of a Gilt-head Seabream, Sparus aurata, Farm in the Mediterranean Sea

An environmental recovery study was carried out after the cessation of a gilt-head seabream farm off the Mediterranean coast of Spain. Physicochemical variables of sediments, in situ benthic fluxes of oxygen and nutrients, and benthic macrofauna were measured in the farming area and at a control station. Five sampling campaigns were done, one before the closure and the others at 1, 3, 9, and 24 mo after cessation. Benthic flux of ammonium was the first variable to recover, followed by benthic fluxes of phosphate and dissolved oxygen and percentage organic matter in the sediments, which 3 mo after the cessation of farming already showed levels similar to those in the control station. Nine months after cessation, the other abiotic variables of the sediments disturbed by the activity had recovered, such as percentage coarse fraction, total phosphorus concentrations, and redox potential measurements. The recovery of the macrofauna was slower than the abiotic variables. Three months after cessation, Capitella capitata abundance had reduced drastically in the farming area, but similar specific richness levels were not observed between the two sampled zones until 2 yr after farming cessation.
Temperature dependence of tunnel magnetoresistance

Electric transport through magnetic tunnel junctions (MTJs) has been studied at various temperatures to gain understanding of the transport mechanisms in such devices. Between 15 and 400 K, MTJs with Al2O3 barriers have been tested at low voltage (barrier height: 2.0–2.1 eV, barrier width: 1.5 nm). For the soft-magnetic electrode a sputtered 1 nm Co/6 nm Fe double layer was used. The hard-magnetic electrode is realized with a 1.5 nm Co/1.0 nm Cu/1.0 nm Co system. Antiferromagnetic coupling between the two Co layers leads to a high saturation field. The 1.5 nm Co layer is used as the second electrode of the MTJ. The conductance increases with growing temperature while the tunnel magnetoresistance (TMR) shows a slight decrease. For interpretation of the results, the temperature dependence of direct tunneling, of the hopping conductance via trapped states, and of the interface magnetization have to be taken into consideration. The dominant factor for the TMR is proportional to 1−BT3/2 and follows the tempera.

Effect of roasting on physicochemical and functional properties of flaxseed flour

Abstract An investigation was carried out on the physical, physicochemical, and functional properties of flaxseed. Physical properties viz. seed shape and size, geometric and arithmetic mean diameter, sphericity, aspect ratio, bulk and true density, porosity, angle of repose, and static friction coefficient were determined. Geometric and arithmetic mean diameter were 2.19 and 3.51 mm while average sphericity and aspect ratio were 40.34 and 62.58%. The average true density, bulk density, and porosity were 1.34 g/cm3, . 66 g/cm3, and 51.56%. Angle of repose was 19.40° and coefficient of static friction obtained on glass, stainless steel, plywood perpendicular, and plywood parallel was . 32, . 36, . 33, and . 33, respectively. Flaxseeds were roasted and compositional and functional properties like water absorption capacity (WAC), oil absorption capacity (OAC), foaming capacity, foaming stability, sedimentation value, and least gelation concentration of roasted and unroasted flaxseed flour were performed. Foaming capacity (9.23%) and foaming stability (54.43%) were significantly higher for unroasted flaxseed than roasted flaxseed flour (7.82 and 48.60%). Roasted flour was observed to have highest values of WAC, bulk density, WSI, ash, fiber, carbohydrate, and lowest values of moisture, protein, fat, OAC, tap density, porosity, angle of repose, WAI, and sediment value as compared to unroasted flour.
Effect of Osmopriming Duration on Germination, Emergence, and Early Growth of Cowpea (Vigna unguiculata (L.) Walp.) in the Sudan Savanna of Nigeria

Seed osmopriming could be a sustainable method to increase crop establishment, uniform emergence, and growth of plant on the field. Laboratory and field studies were carried out in 2010 cropping season at Usmanu Danfodiyo University, Sokoto, to study the effect of seed osmopriming duration on the germination, emergence, and growth of cowpea seeds. Treatments consisted of three osmopriming duration (soaking in 1% KNO3 salt for 6, 8, and 10 hrs), one hydroprimed control (10 hr), and an unprimed control. These five treatments were laid out in a completely randomized design (CRD) replicated four times. The results showed that osmopriming with KNO3 for different durations was at par but was superior to unprimed treatments in terms of seed germination, emergence, plant height, and dry matter accumulation at 3 weeks after sowing. From this study, it can therefore be concluded that seeds of cowpea could be primed (both hydro and osmopriming) for increased performance. However, osmopriming with KNO3 salt (soaked in 1% KNO3 salt solution and dried before sowing) for 6 hours could result in greater seed germination and seedling height than hydropriming.
A Low-intensity Approach for Early Intervention and Detection of Childhood Disability in Central Java: Long-term Findings and Implications for “Inclusive Development”

Purpose: This paper describes a qualitative follow-up study, conducted eight years after completion of a low-intensity early intervention and detection of childhood disability project in Central Java, Indonesia. The original project sought to increase the level of skills and engagement of existing community health volunteers, for the support of children with disabilities. This followup study explored long-term outcomes and implications for the inclusive development approach. Method: Semi-structured interviews were conducted with 18 of the original volunteers. Interview notes were translated and thematically categorised. results: While the study was qualitative and descriptive, results indicate that despite the low intensity of the project, some early detection and prevention activities were still going on eight years later. conclusions: The study suggests that a low-intensity initiative such as this, which is closely aligned with the goals of a government department, may indeed achieve some ongoing change by extending the focus of the department towards disability-related concerns. Implications: Implications are drawn for the emerging area of “inclusive development”, which similarly seeks to promote change in mainstream services for the benefit of people with disabilities.

Association of yellowfi n tuna (Thunnus albacares) with tracking vessels during ultrasonic telemetry experiments

Abstract— Three yellow ﬁ n tuna ( Thun -nus albacares ) carrying ultrasonic depth-sensitive transmitters developed a strong association with the tracking vessel, following it at speeds up to 5 knots (2.6 m/s). Two ﬁ sh associated with the tracking vessel during day-time, and the other ﬁ sh during day and night periods. Swimming behavior appeared to depend on the speed of the vessel. The tuna remained within a few meters of the surface when the vessel was traveling at high speeds but moved deeper when the vessel drifted. The behavior of these ﬁ sh is compared to those of other yellow ﬁ n tuna tracked in other situations (associated with ﬁ sh-aggregating devices or unassociated with devices). The reasons for these associations are not known but some hypotheses are advanced. ing ultrasonic telemetry experiments. Our objective was to characterize these associations and to compare them with other types of association behavior. We discuss these observations in relation to some hypotheses on the nature of tuna associations with ﬂ oating objects and propose ideas for future studies.
Text-independent talker identification system combining connectionist and conventional models

Several techniques have been used for speaker identification which have different characteristics and capabilities. The respective merits of three different systems respectively employing neural networks, hidden Markov models, and multivariate autoregressive models are compared. A novel text-independent speaker identification system based on the cooperation of these different techniques is presented. This system outperforms previous models and can handle a large number of speakers. It is argued that modular architectures present significant advantages, such as their learning speed, their generalization and representation capabilities, and their ability to satisfy constraints imposed by hardware limitations. <<ETX>>
Broadband meter‐wavelength observations of ionospheric scintillation

Intensity scintillations of cosmic radio sources are used to study astrophysical plasmas like the ionosphere, the solar wind, and the interstellar medium. Normally, these observations are relatively narrow band. With Low‐Frequency Array (LOFAR) technology at the Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) station in northern Finland we have observed scintillations over a three‐octave bandwidth. “Parabolic arcs,” which were discovered in interstellar scintillations of pulsars, can provide precise estimates of the distance and velocity of the scattering plasma. Here we report the first observations of such arcs in the ionosphere and the first broadband observations of arcs anywhere, raising hopes that study of the phenomenon may similarly improve the analysis of ionospheric scintillations. These observations were made of the strong natural radio source Cygnus‐A and covered the entire 30–250 MHz band of KAIRA. Well‐defined parabolic arcs were seen early in the observations, before transit, and disappeared after transit although scintillations continued to be obvious during the entire observation. We show that this can be attributed to the structure of Cygnus‐A. Initial results from modeling these scintillation arcs are consistent with simultaneous ionospheric soundings taken with other instruments and indicate that scattering is most likely to be associated more with the topside ionosphere than the F region peak altitude. Further modeling and possible extension to interferometric observations, using international LOFAR stations, are discussed.
