TESTING DISSIPATIVE MAGNETOSPHERE MODEL LIGHT CURVES AND SPECTRA WITH FERMI PULSARS

We explore the emission properties of a dissipative pulsar magnetosphere model introduced by Kalapotharakos et al. comparing its high-energy light curves and spectra, due to curvature radiation, with data collected by the Fermi LAT. The magnetosphere structure is assumed to be near the force-free solution. The accelerating electric field, inside the light cylinder (LC), is assumed to be negligible, while outside the LC it rescales with a finite conductivity (σ). In our approach we calculate the corresponding high-energy emission by integrating the trajectories of test particles that originate from the stellar surface, taking into account both the accelerating electric field components and the radiation reaction forces. First, we explore the parameter space assuming different value sets for the stellar magnetic field, stellar period, and conductivity. We show that the general properties of the model are in a good agreement with observed emission characteristics of young γ-ray pulsars, including features of the phase-resolved spectra. Second, we find model parameters that fit each pulsar belonging to a group of eight bright pulsars that have a published phase-resolved spectrum. The σ values that best describe each of the pulsars in this group show an increase with the spin-down rate ( E ˙ ) ? > and a decrease with the pulsar age, expected if pair cascades are providing the magnetospheric conductivity. Finally, we explore the limits of our analysis and suggest future directions for improving such models.
A Note on Equity Premia in Markets with Heterogeneous Agents

We analyze a static partial equilibrium model where the agents are not only heterogeneous in their beliefs about the return on risky assets but also in their attitude to it. While some agents in the economy are subjective utility maximizers others behave ambiguity averse in the sense of Knight (1921). If ambiguity averse agents meet overly optimistic subjective utility maximizers in the market lower equity premia can arise in the equilibrium than in a purely subjective utility framework.
Work-family psychological contract, job autonomy and organizational commitment

Problem statement: With the increase in dual-career couples in the wo rkforce and absence of adequate legal contracts in the form of work-fam ily policies, employees may hold expectations regarding employer's obligation based on what has b een promised by the organization regarding work- family benefits. Employees' expectations of obligat ions from an employer may depend on psychological mechanisms or psychological contracts rather than formalisms arising from laws. Despite the existence of earlier studies on psychol ogical contract, the contract has been studied as a global concept. Approach: This study had applied the global psychological co ntract concept to a more specific concept that was work-family psychological contract. Since earlier studies had established the relationship between psychological contract and organizational commitment as well as the effect of job autonomy on this contract, this study examin ed the mediating role of work-family psychological contract in the relationship between job autonomy and organizational commitment. Using self-administered data were collected from 30 7 employees in media organizations in Malaysia. Results: Results of correlation analyses revealed that job autonomy was correlated to work- family psychological contract and organizational co mmitment and work-family psychological contract was related to organizational commitment. The resul ts also indicated that work-family psychological contract partially mediated the relationship betwee n job autonomy and organizational commitment. Conclusion/Recommendations: Employees with greater freedom to make their own decisions at work would have stronger beliefs that the organization c an fulfill promises regarding work-family benefits and they can in turn be more committed to the orga nization.
Schrödinger-Poisson–Vlasov-Poisson correspondence

The Schrodinger-Poisson equations describe the behavior of a superfluid Bose-Einstein condensate under self-gravity with a 3D wave function. As ℏ/m→0, m being the boson mass, the equations have been postulated to approximate the collisionless Vlasov-Poisson equations also known as the collisionless Boltzmann-Poisson equations. The latter describe collisionless matter with a 6D classical distribution function. We investigate the nature of this correspondence with a suite of numerical test problems in 1D, 2D, and 3D along with analytic treatments when possible. We demonstrate that, while the density field of the superfluid always shows order unity oscillations as ℏ/m→0 due to interference and the uncertainty principle, the potential field converges to the classical answer as (ℏ/m)2. Thus, any dynamics coupled to the superfluid potential is expected to recover the classical collisionless limit as ℏ/m→0. The quantum superfluid is able to capture rich phenomena such as multiple phase-sheets, shell-crossings, and warm distributions. Additionally, the quantum pressure tensor acts as a regularizer of caustics and singularities in classical solutions. This suggests the exciting prospect of using the Schrodinger-Poisson equations as a low-memory method for approximating the high-dimensional evolution of the Vlasov-Poisson equations. As a particular example we consider dark matter composed of ultralight axions, which in the classical limit (ℏ/m→0) is expected to manifest itself as collisionless cold dark matter.
Divergent effects of detachment from work: a day-level study on employee creativity

ABSTRACT Detachment from work during non-work time is generally related to a decrease in work-related strain. However, it might also hamper employees’ generation of new and useful ideas about work by completely shutting off work-related thoughts and/or feelings outside of work. In this day-level study, we used a within-person design to investigate the role of cognitive and emotional detachment from work during non-work time in relation to equivalent types of job demands and job resources, in the prediction of employee creativity. Cognitive detachment from work refers to mentally disconnecting from work and no longer thinking about job-related issues, whereas emotional detachment from work refers to affectively disconnecting from work and no longer experiencing job-related emotions. Survey data were gathered over the course of eight consecutive days from 151 health care employees. Multi-level analyses revealed that: (1) cognitive detachment was positively related to creativity, irrespective of the level of cognitive job demands and resources; (2) high emotional job demands in combination with either low levels of emotional detachment or high levels of emotional job resources were positively related to creativity. This day-level study provides insight into the relation between detachment from work and creativity from a process perspective, by showing specific conditions under which different types of detachment from work benefit employee creativity.
Reshaping Risk Disclosure through Integrated Reporting: Evidence from Italian Early Adopters

The purpose of this paper is to explore Integrated Reporting (IR) and risk disclosure (RD) and demonstrating the interconnection between business strategies and risk. Through a content analysis, the paper explores the management commentary and Integrated reporting of Italian companies at the end of 2015.The study reveals that many of the companies have embedded financial reporting into IR. We find extensive information about risks and opportunities, in relation to the management of the six capitals. The paper represents an investigation into risk disclosure in IR. It adds knowledge to the opportunity offered by IR in meeting stakeholder’s information needs, compared to traditional tools of corporate reporting.The results could be of interest both for legislator and standards setters, to bring them up to date with enhanced disclosure of risk and opportunities which IR offers with respect to the more traditional forms of disclosure.This is the first country-based study investigating risk disclosure provided through IR looking at three different dimensions: the metrics of RD (monetary or non-monetary); the outlook orientation (past, present or future) and the type of risk news (good or bad news). The results are relevant to detect how companies act and what can be done to improve risk disclosure.
Respiration in the scyphozoan jellyfish Aurelia aurita and two hydromedusae (Sarsia tubulosa and Aequorea vitrina): effect of size, temperature and growth

The effect of body size on respiration was examined in the common scyphozoan jellyfish Aurelia aurita (ephyrae and medusae) and in 2 hydromedusae, Sarsia tubulosa and Aequorea vitrina. The starvation respiration rate (RM, µl O2 d -1 ) as a function of dry body weight (W, mg) could be expressed by means of the equation RM = aW b , and was determined to be 18.9W 0.76 for A. aurita (ephyrae and medusae), 19.4W 0.91 for S. tubulosa, and 2.39W 1.02 for A. vitrina. Further, the effect of temperature, feeding and growth on respiration was studied in A. aurita. The weight-specific respi- ration rate (RW, µl O2 (mg dry wt) -1 d -1 ) increased exponentially with temperature (T, °C) within the 7 to 22°C interval at RW = 0.93e 0.11T (Q10 = 3.1). A. aurita ephyrae responded rapidly to the presence of food, and maximum respiration rate was attained after 4 h; after the supply of food was stopped, the respiration rate decreased to the starvation level within 2.5 h. Respiration was measured in A. aurita that were fed different concentrations of an assortment of prey organisms (copepods, rotifers, cirriped larvae, Artemia sp.) to obtain a spectrum of specific growth rates. The weight- specific respiration rate as a function of the weight-specific growth rate was linear, and from the slopes of the regression lines the energetic cost of growth was found to be equivalent to 209% of the growth of A. aurita ephyrae feeding on a variety of prey organisms, and 69 and 42% of the growth of A. aurita medusae preying on Artemia sp. and Acartia tonsa respectively.
12 A . 1 LESSONS LEARNED ON SHORT-TERM EXPLICIT PREDICTION OF STORMS THROUGH A JOINT IHOP

An across-laboratory research program, named STEP (Short Term Explicit Prediction), was established at the National Center for Atmospheric Research (NCAR) in 2006 with the objective of improving the short term explicit (convection permitting) forecasting of high impact weather. The STEP program enables the coordination of NCAR’s exiting wide-range of activities and expertise across the institution with emphasized themes to achieve this objective. These activities range from basic understanding of high impact weather to development and real-time demonstration of data assimilation and forecasting systems. Last year, STEP organized a joint retrospective study using IHOP_2002 data with the participation of eight projects covering topics of basic understanding of deep convective systems, high-resolution data assimilation and numerical forecasting, physical parameterization, nowcasting system, and advanced verification technique. The main objective of the joint retrospective study was to evaluate the current capabilities, which are developed at NCAR with the goal of supporting the research and operational community, for short-term (0-12 hours) explicit forecasting of storms. The objective of this paper is to report what we have done and learned on the modeling aspect of the joint study, with the emphasis on model initialization and sensitivity of physical parameterizations. The period of June 10-16, 2002 was
Liquidity Risk, Speculative Trade, and the Optimal Latency of Financial Markets

Garbade and Silber (1979) demonstrate that an asset will be liquid if it has (1) low price volatility and (2) a large number of public investors who trade it. Although these results match nicely with common notions of liquidity, one key element is missing: liquidity also depends on (3) an asset s correlation with other securities. For example, if an illiquid asset is highly correlated with a liquid asset, then speculators will naturally step in and make it liquid . In this paper, we update Garbade and Silber s model to include an infinitely liquid market security. We show that when the market security is added, the liquidity of the non-market asset is still a decreasing function of volatility and an increasing function of investor participation, but it is now also an increasing function of its correlation with the market. Furthermore, we show that at a critical correlation value of 0.86, it is optimal for the asset to continuously clear, i.e., for orders to transact immediately when placed in the market. This low-latency result holds regardless of the other properties of the asset. The updated model can help answer several questions relevant to current financial markets: How and why do short-term speculators provide liquidity in markets? , How much benefit do these speculators add? , and Can extremely low-latency in markets be beneficial?
A new method for calculating the convergent point of a moving group

Context. Convergent point (CP) search methods are important tools for studying the kinematic properties of open clusters and young associations whose members share the same spatial motion. Aims. We present a new CP search strategy based on proper motion data. We test the new algorithm on synthetic data and compare it with previous versions of the CP search method. As an illustration and validation of the new method we also present an application to the Hyades open cluster and a comparison with independent results. Methods. The new algorithm rests on the idea of representing the stellar proper motions by great circles over the celestial sphere and visualizing their intersections as the CP of the moving group. The new strategy combines a maximum-likelihood analysis for simultaneously determining the CP and selecting the most likely group members and a minimization procedure that returns a refined CP position and its uncertainties. The method allows one to correct for internal motions within the group and takes into account that the stars in the group lie at different distances. Results. Based on Monte Carlo simulations, we find that the new CP search method in many cases returns a more precise solution than its previous versions. The new method is able to find and eliminate more field stars in the sample and is not biased towards distant stars. The CP solution for the Hyades open cluster is in excellent agreement with previous determinations.
Effect of Integrated Exercise Protocol in Lumbar Spinal Stenosis as Compare with Conventional Physiotherapy- A Randomized Control Trial

Background context: Lumbar Spinal Stenosis (LSS) is one of the most common spinal pathologies in India. Spinal stenosis is narrowing of the spinal canal with encroachment on the neural structures by surrounding bone and soft tissue. While it is widely held that conservative management should be the first line of approach in patients with LSS, little is known about the efficacy of non-surgical treatments for this condition. Purpose: To compare the specific integrated exercise program with conventional physical therapy programs for patients with LSS. Study design: Experimental study. Method: 30 patients (experimental group, n=15; control group, n=15) with lumbar spinal stenosis were randomized to one of two 3 week physical therapy programs. One program included exercise program (Flexibility exercise, Specific experimental canal enlargement exercise, strengthening exercise, functional/recreational activities), while the other included electrotherapy and exercise program (Hot fomentation, IFT, Flexion Exercises). Outcome measures: Perceived recovery was assessed with an Oswestry Disability Questionnaire (ODQ). Secondary outcomes included: Numeric Pain Rating Scale (NPRS), Straight Leg Raise, Slump test and Modified Schober Test (MST). Results: Result shows that the significant improvement in Quality of life, intensity of pain, lumbar ROM and Neural Flexibility was seen in Group A but it was not showing significant results in Group B. This signifies that group A has more significant improvement than Group B. Conclusion: From the result analysis we found that the integrated exercise approach has a significant effect then a conventional physiotherapy treatment.

A Structure-Reconfigurable Series Resonant DC–DC Converter With Wide-Input and Configurable-Output Voltages

This paper proposes a new series resonant dc–dc converter with four configurable operation states depending on the input-voltage and output-voltage levels. It suits well for the dc–dc stage of grid-connected photovoltaic systems with a wide-input voltage range and different grid voltage levels, i.e., 110/120 V and 220/230/240 V. The proposed converter consists of a dual-bridge structure on the primary side and a configurable half- or full-bridge rectifier on the secondary side. The root-mean-square (RMS) currents are kept low over a fourfold voltage-gain range; the primary-side mosfets and secondary-side diodes can achieve zero-voltage switching on and zero-current switching off, respectively. Therefore, the converter can maintain high efficiencies over a wide voltage gain range. A fixed-frequency pulsewidth-modulated control scheme is applied to the proposed converter, which makes the gain characteristics independent of the magnetizing inductance and thereby simplifies the design optimization of the resonant tank. The converter topology and operation principle are first described. Then, the characteristics, i.e., the dc voltage gain, soft switching, and RMS currents, are detailed before a performance comparison with conventional resonant topologies is carried out. Furthermore, the design guidelines of the proposed converter are also presented. Finally, the experimental results from a 500-W converter prototype verify the feasibility of the proposed converter.
Complex Multidisciplinary Follow-Up Of Children With Neurofibromatosis Type 1

Abstract Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant disorders with mainly mild cutaneous manifestations. Some patients with NF1, however, develop severe complications such as progressive optic pathway glioma, plexiform neurofibroma or malignant peripheral nerve sheath tumour. Due to potentially progressive and asymptomatic course of the disease, patients with NF1 require a regular multidisciplinary follow-up in coordination with various specialties and early intervention. In this article, we summarise our long-term experience with multidisciplinary follow-up of NF1 patients in the Centre for Neurofibromatosis Type 1 patients at the Children's University Hospital in Bratislava.
Effect of a fire retardant on the ignition of pine wood exposed to smoldering particles of pine bark

This paper represents the laboratory research results on the interaction of smoldering pine bark particles with pine wood. Fire retardant treatment "FUKAM" was studied to estimate its effect on the probability of wood ignition. The wind speed and the number and geometric sizes of particles were varied in the experiments. The results have shown that the increase in the wind speed leads to the increase in the probability of wood ignition by the particles of the same size, and fire-retardant treatment significantly increases the protective properties of wood exposed to smoldering pine bark particles.
Comparing levels of career indecision among selected honours degree students at the University of Pretoria

Career indecision plays a major role in the way students perceive their future career prospects and how they approach these prospects. In addition, career indecision influences career-related thoughts and decisions, and plays a role in the way students formulate career goals. A convenience sample from honours students in Accounting Sciences, Financial Management, Economics and Marketing was drawn and their levels of career indecision were measured using self-administered questionnaires. The study demonstrates that differences exist between students whose employment status differs, and those who were studying for different degrees. Consequently, this study has vital implications for groups (such as career counsellors and educational institutions) involved in the career decision-making processes of university students.
Rapid isolation/selection of best yeast culture and its metabolic control for the biotransformation of benzaldehyde to 1-hydroxy-1-phenyl-2-propanone.

Present work describes the rapid isolation and selection of thirteen yeast culture having high resistance to acetaldehyde and benzaldehyde, directly added to the medium at isolation stage. All isolates had 100% similarity with type strain Saccharomyces cerevisiae during molecular characterization. S. cerevisiae APL-2 showed better kinetic parameters and ultimately lead to better production of 1-hydroxy-1-phenyl-2-propanone. This fermentation involved two phases, first phase to attain the suitable level of cell density while second phase is the biotransformation phase. Effect of temperature (15-30°C) was studied during second phase (at the time of acetaldehyde and benzaldehyde dozing). The maximum level of biotransformation was achieved when temperature was maintained at 15-18°C. Addition of benzyl alcohol also enhanced the biotransformation level.
The Role of Perceived Control in Customer Value Cocreation and Service Recovery Evaluation

Treating customers as passive recipients of service recovery does not account for their naturally elevated desire for control following a service failure. Focusing on value cocreation by customers in service recovery, this study conceptualizes three types of customer perceived control in service recovery: process control, decision control, and information control. Using both a field study and a controlled experiment to test the conceptual model, this study reveals various ways service firms can engage customers in service recovery to enhance their service experience. The results show that customers are motivated to exert influence on and regain control over service recovery because they care not only about the economic gains rendered by control but also about their social self-esteem in their relationship with a service firm. An investigation of the interaction effects among the three types of control reveals either complementary or substitution effects between different pairings of the three types of control on customers’ justice evaluations of service recovery and repurchase intentions. The findings provide managers with new guidance on developing and implementing successful service recovery programs.
