Calibration of Gamma-Ray Burst Luminosity Indicators

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Several gamma-ray burst (GRB) luminosity indicators (LIs)have been proposed. Unlike SNe Ia, calibration of GRB LIs using a low-redshift sample is difficult. Based on the Bayesian theory, here we propose an approach to calibrate these LIs without introducing a low-redshift GRB sample. The essential points of our approach include, (1) calibrate the power-law indices in the LIs with a sample of GRBs in a narrow redshift range (Delta z); and (2) marginalize the coefficient of the LIs over a reasonable range of cosmological parameters. We take our newly discovered multivariable GRB LIs as an example and test the validity of our approach through simulations. We show that while the coefficient strongly depends on the cosmological parameters, the power-law indices do not as long as Delta z is small enough. The selection of Delta z for a particular GRB sample could be judged according to the size and the observational uncertainty of the sample. There is no preferable redshift to perform the calibration of the indices, while a lower redshift is preferable for the marginalization of the coefficient. The best strategy would be to collect GRBs within a narrow redshift bin around a fiducial intermediate redshift (e.g. z~1 or z~2), since the observed GRB redshift distribution is found to peak around z=(1 - 2.5). Our simulation suggests that with the current observational precision of measuring GRB isotropic energy, spectral break energy, and the optical temporal break time, 25 GRBs within a redshift bin of Delta z ~ 0.30 would give fine calibration to our luminosity indicator(abridged).

description: Over the last two decades electricity sectors in both developed and developing countries have been subject to restructuring to introduce private capital and increase competition. This has been accompanied by the introduction of new regulatory regimes. Although the effects of such reforms in a number of the developed economies are now well documented, apart from a few case studies, the experience of developing countries is much less well researched. This is important because privatisation, competition and the reform of state regulation are key themes in donor aid programmes, notably of the World Bank. This paper provides an econometric assessment of the effects of privatisation, competition and regulation on the performance of the electricity generation industry using panel data for 51 developing countries, over the period 1985 to 2000. The study identifies the impact of these reforms on generating capacity, electricity generated, labour productivity in the generating sector, capacity utilisation and industrial and residential user prices. The paper concludes that competition appears to bring about favourable results for service penetration, capacity expansion, labour efficiency and prices to industrial users. The effect of privatisation and having an independent regulator, separately, is statistically insignificant except in the case of capacity utilisation and privatisation; while the co-existence of these two reforms does seem to be correlated with greater electricity availability, more generation capacity and higher labour productivity. The main policy conclusions are that on their own privatisation and regulation do not lead to obvious gains in economic performance. When privatising electricity under conditions of monopoly, emphasis should be placed on implementing an effective regulatory framework. By contrast, introducing competition does seem to be effective in stimulating performance improvements, irrespective of changes in ownership or regulation.
The combination of de Broglie's Harmony of the Phases and Mie's theory of gravity results in a Principle of Equivalence for Quantum Gravity

description: Under a Lorentz-transformation, Mie's 1912 gravitational mass behaves identical as de Broglie's 1923 clock-like frequency. The same goes for Mie's inertial mass and de Broglie's wave-like frequency. This allows the interpretation of de Broglie's "Harmony of the Phases" as a "Principle of Equivalence" for Quantum Gravity. Thus, the particle-wave duality can be given a realist interpretation. The "Mie-de Broglie" interpretation suggests a correction of Hamilton's variational principle in the quantum domain. The equivalence of the masses can be seen as the classical "limit" of the quantum equivalence of the phases.

description: We studied the filament structures and dense cores in OMC-2,3 region in Orion A North molecular cloud using the high-resolution N2H+ (1-0) spectral cube observed with the Atacama Large Millimeter/Submillimeter Array (ALMA). The filament network over a total length of 2 pc is found to contain 170 intersections and 128 candidate dense cores. The dense cores are all displaced from the infrared point sources (possible young stars), and the major fraction of cores (103) are located around the intersections. Towards the intersections, there is also an increasing trend for the total column density Ntot as well as the the power-law index of the column-density Probability Distribution Function (N-PDF), suggesting that the intersections would in general have more significant gas assembly than the other part of the filament paths. The virial analysis shows that the dense cores mostly have virial mass ratio of alpha_vir=M_vir/M_gas<1.0, suggesting them to be bounded by the self gravity. In the mean time, only about 23 percent of the cores have critical mass ratio of alpha_crit=M_crit/M_gas<1.0, suggesting them to be unstable against core collapse. Combining these results, it shows that the major fraction of the cold starless and possible prestellar cores in OMC-2,3 are being assembled around the intersections, and currently in a gravitationally bound state. But more extensive core collapse and star formation may still require continuous core-mass growth or other perturbatio

description: The electronic band structure of bulk ferromagnetic iron is explored by angle-resolved photoemission for electron correlation effects. Fermi surface cross-sections as well as band maps are contrasted with density functional calculations. The Fermi vectors and band parameters obtained from photoemission and their prediction from band theory are analyzed in detail. Generally good agreement is found for the Fermi surface. A bandwidth reduction for shallow bands of ~ 30 % is observed. Additional strong quasiparticle renormalization effects are found near the Fermi level, leading to a considerable mass enhancement. The role of electronic correlation effects and the electronic coupling to magnetic excitations is discussed in view of the experimental results.

description: Lesser developed countries (LDCs) serve as both customers and competitors for agricultural commodities produced in the Southern region of the United States. This paper focuses on the impacts of LDCs on exports of the major agricultural commodities produced in the South (cotton, rice, tobacco, poultry, and, to a lesser extent, citrus and peanuts). First the importance of LDCs as export markets for Southern commodities is explored. Then the role LDCs play as producers and exporters of these commodities is considered. Finally, these separate roles are combined into an index of LDC competitiveness with Southern agricultural commodities. Data analysis shows that Southern agricultural interests truly are divided over the role LDCs play in Southern agriculture, where poultry and rice rank highest, and peanuts lowest, in terms of a LDC markets/competition index. Thus, it is not surprising that calls for protectionism (e.g., the Bumpers' Amendment) should arise from the South.
Entropy stable adaptive moving mesh schemes for 2D and 3D special relativistic hydrodynamics

description: This paper develops entropy stable (ES) adaptive moving mesh schemes for the 2D and 3D special relativistic hydrodynamic (RHD) equations. They are built on the ES finite volume approximation of the RHD equations in curvilinear coordinates, the discrete geometric conservation laws, and the mesh adaptation implemented by iteratively solving the Euler-Lagrange equations of the mesh adaption functional in the computational domain with suitably chosen monitor functions. First, a sufficient condition is proved for the two-point entropy conservative (EC) flux, by mimicking the derivation of the continuous entropy identity in curvilinear coordinates and using the discrete geometric conservation laws given by the conservative metrics method. Based on such sufficient condition, the EC fluxes for the RHD equations in curvilinear coordinates are derived and the second-order accurate semi-discrete EC schemes are developed to satisfy the entropy identity for the given convex entropy pair. Next, the semi-discrete ES schemes satisfying the entropy inequality are proposed by adding a suitable dissipation term to the EC scheme and utilizing linear reconstruction with the minmod limiter in the scaled entropy variables in order to suppress the numerical oscillations of the above EC scheme. Then, the semi-discrete ES schemes are integrated in time by using the second-order strong stability preserving explicit Runge-Kutta schemes. Finally, several numerical results show that our 2D and 3D ES adaptive moving mesh schemes effectively capture the localized structures, such as sharp transitions or discontinuities, and are more efficient than their counterparts on uniform mesh.

description: In the past decade, In order to develop corporate governance in Iran, regulatory authorities such as the Central Bank of the Islamic Republic of Iran (CBI) and the Securities & Exchange Organization (SEO) have considered the modern internal auditing through issuing guidelines and requirements in this regards. Due to the gradual exIpansion of the modern internal auditing in Iran, the many challenges surrounding this value-adding profession have been born that limits its effective implementation. On the other hand, many aspects of the internal auditing in Iran, including the internal audit quality (IAQ) and it' S obstacles and barriers, have not been clarified yet. Also, limited areas of the Internal Audit Challenges (IAC) and barriers have been considered in previous research. In order to explain and describe the various aspects of IAC and it’ s Improvement Strategies, by using the qualitative approach and grounded theory, internal audit multi-stakeholders (user, executive, regulators and standard setter) were studied for the first time in Iran. In this regard, 33 people were interviewed. In addition, 30 papers and seminars which published in Iranian professional magazines that reflect the viewpoints of the above-mentioned stakeholders were also used and analyzed. The data were analyzed by using the open coding, axial coding & selective coding approach that are specific to the grounded theory and major categories, categories, and subcategories (concepts) were extracted. Using a system model approach that includes inputs, process, outputs, outcomes and contextual factors, the IAC model as an emerged theory was designed. The model incorporates multidimensional of IAC. The findings suggest that there are many challenges in implementing and achieving the IAQ in many aspects for Iranian organization. Due to these, the multidimensional strategies have been introduced at engagement level, internal audit function level, firm level and national level..
The complexity of a participatory democracy in a public primary classroom : the interplay of student autonomy and responsibility
Creators: name: Collins, Steve
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation presents a case study of a grade one-two class in the suburbs of Vancouver. The twenty-two students are diverse in terms of academic ability, culture, language, age, and personality. Participatory Democracy is researched. Participatory Collaborative Action Research is the methodology. The researcher, classroom teacher, and the students themselves, are immersed in the research setting as partners. Participatory Democracy is an inclusive arrangement where classroom members contribute to decision-making affecting the classroom. Therefore, the research methodology and the research topic are the same activity in which reflection by the participants yields both data and learning outcomes. The research and the classroom community develop together. Within this social orientation, autonomy and responsibility are investigated. An analysis of each concept and their relationship is offered. Possibilities for shared authority are also examined. These and other elements are conceptually intertwined and not easily separated. Complexity Theory is presented as a way of framing classroom research. A Participatory Democratic classroom is conceived of as a dynamic adaptive system, similar to an organism or society. This community is understood ecologically. It is self-organizing and continually coevolving. The importance of a sense of community as a context for learning about social elements becomes evident. An understanding of autonomy, responsibility, shared authority, and their relationship is demonstrated by children through their friendships and sometimes through verbal expression. The students and teacher establish negotiated, dynamic boundaries in which students express their autonomy within the limits of responsibility to the community. Since participation depends on discourse, non-verbal active discourse is encouraged in this community as legitimate communication and a support for language development. Authority, understood as embedded in the community, with the teacher as its interpreter, is shared with students. Rule setting is complex and dynamic, not absolute. Rules are explained and negotiated. An effort to achieve consensus forms the basis of decision-making. Within a democratic community that promotes participation and appreciates the complexity of social structures, the teacher must promote a sense of community, negotiate curriculum, negotiate frames for behavior and learning, plan and assess collaboratively, and reflect on the constantly changing complexity of the classroom community.

description: The performance of restricted estimators such as Almon and Shiller in modeling advertising carryover is tested and compared to the unrestricted OLS estimator, using 1971-1988 monthly New York City fluid milk market data. Results indicate that in the absence of autocorrelation and multicollinearity among the lagged advertising variables, the unrestricted OLS estimator is still the preferred estimator, based on Mean Square Error and Root Mean Square Percent Error criteria. In this case, the Almon and Shiller estimators perform equally well, although next only to the OLS estimator. In the presence of autocorrelation or multicollinearity however, the restricted estimators may outperform the OLS estimator, in a MSE sense, with the flexible Shiller estimator (which subsumes the Almon) being more desirable.

description: We extend the two leading methods for the \emph{ab initio} computational descrip tion of phonon-mediated superconductors, namely Eliashberg theory and density fu nctional theory for superconductors (SCDFT), to include plasmonic effects. Furth ermore, we introduce a hybrid formalism in which the Eliashberg approximation fo r the electron-phonon coupling is combined with the SCDFT treatment of the dynam ically screened Coulomb interaction. The methods have been tested on a set of we ll-known conventional superconductors by studying how the plasmon contribution a ffects the phononic mechanism in determining the critical temperature (\tc). Our simulations show that plasmonic SCDFT leads to a good agreement between predict ed and measured \tc's, whereas Eliashberg theory considerably overestimates the plasmon-mediated pairing and, therefore, \tc. The hybrid approach, on the other hand, gives results close to SCDFT and overall in excellent agreement with exper iments.

description: We present a numerical study of lasing modes in diffusive random media with local pumping. The reabsorption of emitted light suppresses the feedback from the unpumped part of the sample and effectively reduces the system size. The lasing modes are dramatically different from the quasimodes of the passive system (without gain or absorption). Even if all the quasimodes of a passive diffusive system are extended across the entire sample, the lasing modes are still confined in the pumped volume with an exponential tail outside it. The reduction of effective system volume by absorption broadens the distribution of decay rates of quasimodes and facilitates the occurrence of discrete lasing peaks.

description: Supply functions, elasticity estimates, and nonjointness test results consistently indicated that few commodities compete economically in the production of six major Texas vegetables (cabbage, cantaloupes, carrots, onions, potatoes, and watermelons). Significant bias effects caused by government-supported commodities, fixed inputs, and technological change were observed and measured. Nonnested test results for the hypothesis of sequential decision making by vegetable producers were inconclusive, but they gave greater likelihood support to sequential than to contemporaneous decision making.

description: ​International Financial Reporting Standards (IFRS) 13 (fair value measurement) and IFRS 9 (credit loss discount estimate) have allowed financial institutions to report their financial assets and liabilities based on fair value. For banks, the bank facility is one of the financial assets that can be reported by fair value. Disclosure and reporting of cost or fair value of banks facilities as a part of banks financial assets and effect of each method on banks credit loss and risk is one of the significant issues that has always been discussed. Since 1990, the first standard in this area has been issued, the topic, was discussed by academic and professional bodies.the suggestions results show that there are different opinions about using the fair value method. In this paper, we use cost data extracted from the financial statements of 23 Iranian banks the period of 2007-2015 and estimate their fair value of loans. we examine effects of their fair value and cost on banking credit loss. To estimate the fair value, we used cash flow discount model proposed by Federal Reserve of America. The results for Iranian banking system show that the cost of loans method in comparison with the fair value method is better in forecasting banks credit loss

description: With the rapid increase in consumption of some livestock products in Indonesia, expansion of domestic production of these commodities may enhance smallholders' incomes, increase rural employment and add to the country's trade balance. Policy analysis matrices (PAMs) were constructed to estimate divergences between private and social costs and returns in poultry and pig production in selected regions of Indonesia. In each case, producers' use of capital was subsidized but feed input private costs exceeded social values, and output prices received by producers fell short of values based on world prices. Production of all products as import substitutes was socially profitable, but in many instances private returns to farmers were negative. Product price and feed cost divergences were the major policy-induced distortions. Reform of these policies was estimated in a static partial equilibrium framework to lead to supply expansions of each livestock product, a contraction in livestock product consumption, and therefore additional net foreign exchange earnings from the poultry and pig sectors of around $320 million.
Matrix Models and Deformations of JT Gravity

description: Recently, it has been found that JT gravity, which is a two-dimensional theory with bulk action $ -\frac{1}{2}\int {\mathrm d}^2x \sqrt gϕ(R+2)$, is dual to a matrix model, that is, a random ensemble of quantum systems rather than a specific quantum mechanical system. In this article, we argue that a deformation of JT gravity with bulk action $ -\frac{1}{2}\int {\mathrm d}^2x \sqrt g(ϕR+W(ϕ))$ is likewise dual to a matrix model. With a specific procedure for defining the path integral of the theory, we determine the density of eigenvalues of the dual matrix model. There is a simple answer if $W(0)=0$, and otherwise a rather complicated answer.

description: This article reviews and critiques the frontier literature dealing with farm level efficiency in developing countries. A total of 30 studies from 14 different countries are examined. The country that has received most attention is India, while rice has been the most studied agricultural product. The average technical efficiency (TE) index from all the studies reviewed is 72%. The few studies reporting allocative and economic efficiency show an average of 68% and 43%, respectively. These results suggest that there is considerable room to increase agricultural output without additional inputs and given existing technology. Several of the studies reviewed have sought to explain farm level variation in TE. The variables most frequently used for this purpose have been farmer education and experience, contacts with extension, access to credit, and farm size. With the exception of farm size, the results reveal that these variables tend to have a positive and statistically significant impact on TE. This paper shows that considerable effort has been devoted to measuring efficiency in developing country agriculture using a wide range of frontier models. Despite all this work, the extent to which efficiency measures are sensitive to the choice of methodology remains uncertain.

description: We determine all positive harmonic functions for a large class of "semi-isotropic" random walks on the lamplighter group, i.e., the wreath product of the cyclic group of order q with the infinite cyclic group. This is possible via the geometric realization of a Cayley graph of that group as the Diestel-Leader graph DL(q,q). More generally, DL(q,r) is the horocyclic product of two homogeneous trees with respective degrees $q+1$ and $r+1$, and our result applies to all DL-graphs. This is based on a careful study of the minimal harmonic functions for semi-isotropic walks on trees.

description: A multiple antenna base station (BS) with an intelligent reflecting surface (IRS) platform, and several single antenna users are considered in the downlink mode. Simultaneous wireless information and power transfer (SWIPT) is utilized by the BS via transmit beamforming to convey information and power to all devices. Each device applies power splitting (PS) to dedicate separate parts of received power to information decoding and energy harvesting. We formulate a total transmit power minimization problem to jointly design the BS beamforming vectors, IRS phase shifts, and PS ratios at the receivers subject to minimum rate and harvested energy quality of service (QoS) constraints at all the receivers. First, we develop a block coordinate descent algorithm, also known as alternating optimization that can decrease the objective function with every iteration with guaranteed convergence. Afterwards, two low-complexity sub-optimal algorithms that rely on well-known maximum ratio transmission and zero-forcing beamforming techniques are introduced. These algorithms are beneficial when the number of BS antennas and/or number of users are large, or coherence times of channels are small. Simulations corroborate the expectation that by deploying a passive IRS, BS power can be reduced by $10-20$ dBw while maintaining similar guaranteed QoS. Furthermore, even the proposed sub-optimal algorithms outperform the globally optimal SWIPT solution without IRS for a modest number of IRS elements.

description: A conceptual model links agricultural profits, capital gains, interest rates, and property taxes to the sale of agricultural land by profit-maximizing owners. The model motivates an empirical analysis of New Jersey data from 1949 to 1990. Results suggest that nonagricultural considerations may overpower the economic incentives provided by such policies as farmland assessment. Consequently, alternative policies (e.g., purchase of development rights and land use zoning) may be needed to sustain agriculture in rapidly urbanizing areas.

description: Objective: This study examines the challenges and opportunities in impelimenting of International Standard of Auditing 700 (revised 2015) and 701 (new) in Iran in terms of the recent transformations in auditor report and potential impacts of its change on various political, legal and economic environments.
Methods: We perform qualitative content analysis and in-depth interview among experienced group of 18 auditors and 15 investors.
Results: This study has identified the defects in the present report in Iran (Form, content, presentation of the auditor report) and its roots (economic, legal, the audit profession, corporate reporting, auditing standards and expectations), as well as the challenges (auditor resistance, problems in execution of standards, increase in reporting risks, client resistance and increased probability of confusion and diversity in user perception of Key Audit Matters) Opportunities (promotion of auditor report and the audit profession, enhanced relations, improved investor decision making and management assistance) and the required strategies (training, adequate standard setting performance warrantees and method of performance) for the proper execution of the new audit report. Moreover, Key Audit Matters from the point of view of auditors and investors as well as other informational needs of investors have been extracted from the audit report.
Conclusion: According to the findings, the current level of the report is quite different from standard levels being applied, and effective action is required for resolving defects observed in the current auditor report, including increased supervision on the audit profession by related authorities as well as an increase in the quality of the auditor report. Moreover, findings of this research shall contribute to the body of knowledge in the field of auditing, and provide a perception- through consideration of opportunities (including upgrading the auditor report and the audit profession, improving investor decision making, etc.) and challenges encountered (such as auditor and client resistance, etc.)- by regulators including standard setting authorities in auditing, the Securities Exchange Organization can act as supervisory authorities and pave the way towards more effective achievement of objectives set for the new audit report.
A blow-up result for a generalized Tricomi equation with nonlinearity of derivative type

Subjects: subject: Analysis of PDEs (math.AP)

description: In this note, we prove a blow-up result for a semilinear generalized Tricomi equation with nonlinear term of derivative type, i.e., for the equation $\mathscr{T}_{\!\!\ell} u = |\partial_t u|^p$, where $ \mathscr{T}_{\!\!\ell} = \partial_t^2-t^{2\ell}Δ$. Smooth solutions blow up in finite time for positive Cauchy data when the exponent $p$ of the nonlinear term is below $\frac{\mathscr{Q}}{\mathscr{Q}-2}$, where $\mathscr{Q}=(\ell+1)n+1$ is the quasi-homogeneous dimension of the generalized Tricomi operator $\mathscr{T}_{\!\!\ell}$. Furthermore, we get also an upper bound estimate for the lifespan.
Antiferromagnetic Operators in N=4 Supersymmetric Yang-Mills Theory

description: The spectrum of operators in the su(2) sector of N=4 SYM is bounded because the number of operators is finite. According to the AdS/CFT correspondence, the string spectrum in this sector should be also bounded. In this paper the upper bound on the scaling dimension is calculated in the limit of the large R-charge using Bethe ansatz.

SPATIAL MARKET INTEGRATION: DEFINITION, THEORY, AND EVIDENCE

description: A point-space model of interregional trade is used to define market integration and to explore its implications for modeling spatial price relationships. This analysis indicates that spatial prices are related nonlinearly, contrary to much of the work on spatial price analysis which uses linear models. As an empirical example, corn market integration along the Mississippi River is examined during the Midwest flood of 1993. Higher transport costs during this period significantly reduced the extent of integration and thereby decreased excess demand shock transference across regions.
Quantum random walk of the field in an externally driven cavity

description: Using resonant interaction between atoms and the field in a high quality cavity, we show how to realize quantum random walks as proposed by Aharonov et al [Phys. Rev. A {\bf48}, 1687 (1993)]. The atoms are driven strongly by a classical field. Under conditions of strong driving we could realize an effective interaction of the form $ iS^{x}(a-a^†)$ in terms of the spin operator associated with the two level atom and the field operators. This effective interaction generates displacement in the field's wavefunction depending on the state of the two level atom. Measurements of the state of the two level atom would then generate effective state of the field. Using a homodyne technique, the state of the quantum random walker can be monitored.

Non-parametric Local Pseudopotentials with Machine Learning: a Tin Pseudopotential Built Using Gaussian Process Regression

Year: 2020
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We present novel non-parametric representation math for local pseudopotentials (PP) based on Gaussian Process Regression (GPR). Local pseudopotentials are needed for materials simulations using Orbital-Free Density Functional Theory (OF-DFT) to reduce computational cost and to allow kinetic energy functional (KEF) application only to the valence density. Moreover, local PPs are important for the development of accurate KEFs for OF-DFT as they are only available for a limited number of elements. We optimize local PPs of tin (Sn) using GP regression to reproduce the experimental lattice constants of α- and \b{eta}-Sn, the energy difference between these two phases as well as their electronic structure and charge density distributions, which are obtained with Kohn-Sham Density Functional Theory employing semi-local PPs. The use of a non-parametric GPR-based PP representation avoids difficulties associated with the use of parametrized functions and has the potential to construct an optimal local PP independent of prior assumptions. The GPR-based Sn local PP results in well-reproduced bulk properties of α- and \b{eta}-tin, and electronic valence densities similar to those obtained with semi-local PP.

description: It is shown that spatially homogeneous solutions of the Einstein equations coupled to a nonlinear scalar field and other matter exhibit accelerated expansion at late times for a wide variety of potentials $V$. These potentials are strictly positive but tend to zero at infinity. They satisfy restrictions on $V'/V$ and $V''/V'$ related to the slow-roll approximation. These results generalize Wald's theorem for spacetimes with positive cosmological constant to those with accelerated expansion driven by potentials belonging to a large class.

Subjects: subject: 150103 Financial Accounting
subject: FOS: Economics and business

description: The purpose of the present research is to investigate the outlook of auditors on key auditing matters according to ISA 701. Responses to questionnaires distributed among members of the CPA, indicate that evaluations made by auditors of the basic assumptions that form the basis for recognition and disclosure of financial statement items in the auditor report, the approach taken by the auditor when faced with various risks in the company, accounts with the highest risks of significant fraud including risks of fraud in the auditor report, auditor evaluation of significant events and transactions during the fiscal period as well as matters that hold the highest significance in the financial statements based on the auditor’s judgment have to be identified as key audit matters. From the auditor’s point of view, disclosure of KAM results in enhancement of the informational value of the auditor report and reduction of its uniformity, an increase in professional and legal accountability of the auditor, enhancement of investor decision making, and promotion of audit and financial reporting quality. KAMs differ in and across various industries. Furthermore, auditors believe that disclosure of KAM results in user perception of a piecemeal opinion issued by the auditor on these matters as well as unacceptability of the unmodified audit opinion issued, diversity in Key Audit Matters due to the differing professional judgments applied by auditors, increase in audit fees, negative impact on the client-auditor relationship, increased pressure by client on the auditor and user perception of the auditor as the original source of information. Auditors have also expressed the necessity of guidelines for the identification and disclosure of KAMs and believe that these matters must be disclosed in paragraphs closest in proximity to the auditor opinion and an appropriate heading must be given to each category.

description: This paper identifies factors that influence consumers' seafood safety perceptions and examines how these perceptions affect consumers' anticipated consumption when consumers are provided with additional information relevant to seafood. A recursive system of equations is specified describing consumers' safety perceptions as a function of past experience with seafood, recreational harvest activities, and risk-taking behavior, and describing the influence of safety perceptions on consumers' anticipated demand response to hypothetical information concerning seafood. A telephone survey of randomly selected Rhode Island consumers provided data for the analysis.
