Company characteristics and risk management disclosure: empirical study of manufacturing companies listed on the Indonesia stock exchange

This research aims to obtain empirical evidence on the effect of company characteritics on risk management disclosure (RMD) from the annual reports of manufacturing companies. The sample consists of manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the period 2010–2012. The total sample included 72 companies with three years observation and the examined firms reached 216. Results indicate that independent variables (firm size, profitability, leverage, public ownership, management ownership, and business complexity) have a significant effect on RMD. However, the hypotheses test with partial t-test indicate different results. Firm size (FS) and management ownership (MO) have significant effects, whereas leverage (LEV) has a negative and significant effect on RMD. Other variables, namely profitability (PRO), public ownership (PO), and business complexity (BC), have no significant effect on RMD.
Detection of new dynamical features of two coupled spins with an antiferromagnetic environment

We find a class of spin environment at finite temperature in the thermodyna mics limit models where individual quantum trajectories may depend on parameters that are undetermined by the full open system evolution. Our criteria are functions of the given quantum state and detect genuine multipartite entanglement, purity and information entropy that had not been identified so far. They are experimentally accessible without quantum state tomography and are easily computable as no optimization or eigenvalue evaluation is needed.
Older Adults and Web 2.0 Storytelling Technologies: Probing the Technology Acceptance Model through an Age-related Perspective

ABSTRACT Although digital storytelling bears significant benefits for older users, much remains to be explored regarding their psychosocial attributes that could affect technology acceptance. The Technology Acceptance Model (TAM) is one of the most influential theoretical frameworks in the field and since its first introduction, there have been numerous studies upon its potential modifications throughout different cultures. Based on three factors that have been extensively depicted in age-related literature (chronological age, loneliness, and future time perspective), in this research, we designed a TAM extension in order to gain insights on the elements that influence Greek older adults’ intentions to use online storytelling applications. Through a quantitative approach, we evaluated the proposed model with data collected from 112 participants. Due to our results, TAM has been validated as a robust model, future time perspective had a positive influence on perceived ease of use, while age and loneliness had no statistically significant effect.
Unsteady magnetohydrodynamic flow of some non-Newtonian fluids with slip through porous channel

Received: 20 December 2017 Accepted: 3 April 2018 The numerical analysis for transfer of heat by natural convection on an unsteady Magnetohydrodynamic flow of non-Newtonian fluids through porous channel is considered. Equations governing the model are formulated, simplified and non-dimensionalised. The solution is obtained by employing Crank Nicolson’s type of finite difference discritization. Velocity as well as the temperature distributions for both Prandtl-Eyring and Eyring-Powell non-Newtonian fluid models are examined. Comparism between these two diverse liquid models is made with their graphical illustrations on velocity and temperature profiles. It is observed that the velocity is higher for Prandtl Eyring model than Eyring Powell model. Also, the temperature variation for Prandtl number in Eyring-Powell fluid is a little slower than that of Prandtl-Eyring fluid.

This paper investigates the link between fiscal policy shocks and movements in asset markets using a Fully Simultaneous System approach in a Bayesian framework. Building on the works of Blanchard and Perotti (2002), Leeper and Zha (2003), and Sims and Zha (1999, 2006), the empirical evidence for the U.S., the U.K., Germany, and Italy shows that it is important to explicitly consider the government debt dynamics when assessing the macroeconomic effects of fiscal policy and its impact on asset markets. In addition, the results from a VAR counter-factual exercise suggest that: (i) fiscal policy shocks play a minor role in the asset markets of the U.S. and Germany; (ii) they substantially increase the variability of housing and stock prices in the U.K.; and (iii) government revenue shocks have apparently contributed to an increase of volatility in Italy.
Quantifizierung von Glukosemetabolismus und Hypoxie mittels PET bei Kopf-Hals-Tumoren

Zusammenfassung Der vorliegende Artikel beschäftigt sich mit der Bedeutung der FDG- und der Hypoxie-PET bei Kopf-Hals-Tumoren. Dabei liegt der Fokus auf den verschiedenen Quantifizierungsmöglichkeiten und deren Wertigkeit für die klinische Routine und Forschung. Die FDG-PET erfordert in der klinischen Routine nicht zwingend eine quantitative Analyse. Demgegenüber ist die ausschließlich qualitative Auswertung der Hypoxie-PET durch den im Vergleich zum FDG deutlich niedrigeren Kontrast, den alle Hypoxietracer gemein haben, erschwert. Dem Nachteil des niedrigeren Kontrastes steht hier die strikt eindimensionale Aufnahme bzw. das Verweilen des Hypoxie-Tracers im hypoxischen Gewebe gegenüber, ein eindeutiger Vorteil im Vergleich zum Hochkontrast-Tracer FDG, dessen Aufnahme in Tumorzellen multifaktoriell ist. Es gibt eine Vielzahl quantitativer Parameter, die weit über den scheinbar omnipräsenten, aber keinesfalls unumstrittenen maximalen Standardized uptake value (SUVmax) hinausgehen. Deren Erfordernis und ihr Einfluss auf die klinische Routinediagnostik werden dargestellt und kritisch abgewogen.
An inline pseudoelliptic self‐packaging substrate integrated suspended line filter with mixed electric and magnetic coupling

A novel compact and self‐packaging inline pseudoelliptic filter is proposed. The proposed filter exploits controllable mixed electric and magnetic coupling using substrate integrated suspended line (SISL) technology. Based on a synchronously tuned coupled resonator circuit with parallel LC resonant tank and admittance inverters, general formulas for extracting electric and magnetic coupling coefficients are derived. Meanwhile, a basic mixed coupled SISL resonator pair is investigated and a systematic design procedure of a second‐order mixed coupled SISL filter is also given. Two prototypes of the second‐order filter with one transmission zero (TZ) at either upper or lower stopband are designed, which is corresponding to either magnetic or electric coupling dominant case. Furthermore, for asynchronously tuned coupled resonator cases, an inline third‐order pseudoelliptic SISL filter characterized by symmetric TZs is designed, fabricated, and measured for validation. The simulated and measured results show a good agreement with the synthesized ones.
The temporal dynamics of speeded decision making

This dissertation sheds light on the temporal dynamics of behavior in speeded decision making. Participants on reaction time (RT) tasks learn, get distracted, speed up, slow down, get confused, get bored, and eventually may start guessing. One can safely say that participants' behavior is dynamic. It seems therefore obvious that mean RT or accuracy are at best limited summaries of performance. This thesis shows that a study of the dynamics of speeded decision making requires an assessment of all the data, most notably the changes in entire RT distributions. More generally, this thesis shows that the analysis of psychological data should start from well-formulated ideas about the processes that might have generated the data. When the model that formalizes these ideas provides a reasonable account of the observed data, this constitutes a first step towards a deeper and more comprehensive understanding of behavior than is possible from the assessment of summary measures alone.
Role of Microorganisms in Bioremediation of Pesticides

This chapter describes how exposure to pesticides has become one of the most prominent components of current agriculture. Pesticides have high impact on farmer's economy as they prevent and minimize agricultural losses due to pests (insects, fungi, nematode), improve yield and quality food in terms of superficial appeal. However, these synthetic pesticides have serious environmental concerns and create a variety of toxic effects in living beings. In this regard, the bioremediation approach can be a suitable alternative over the conventional treatment methods for the treatment of pesticides-contaminated sites. Bioremediation is the use of microorganisms or their enzymes to degrade and detoxify the pesticide from the environment. Microbial interactions greatly influence natural bio remedial processes occurring in soil. Microorganisms involved various biochemical mechanisms for the degradation of pesticides, such as oxidation and reduction reactions. This chapter provides an overview on the nature, characteristics and toxicity of pesticides in environment and role of microbes in bioremediation of pesticides.
Understanding and promoting adoption of conservation practices by rural landholders

Research on the adoption of rural innovations is reviewed and interpreted through a cross-disciplinary lens to provide practical guidance for research, extension and policy relating to conservation practices. Adoption of innovations by landholders is presented as a dynamic learning process. Adoption depends on a range of personal, social, cultural and economic factors, as well as on characteristics of the innovation itself. Adoption occurs when the landholder perceives that the innovation in question will enhance the achievement of their personal goals. A range of goals is identifiable among landholders, including economic, social and environmental goals. Innovations are more likely to be adopted when they have a high ‘relative advantage’ (perceived superiority to the idea or practice that it supersedes), and when they are readily trialable (easy to test and learn about before adoption). Non-adoption or low adoption of a number of conservation practices is readily explicable in terms of their failure to provide a relative advantage (particularly in economic terms) or a range of difficulties that landholders may have in trialing them.
Reconciling Compensating Errors Between Precipitation Constraints and the Energy Budget in a Climate Model

Precipitation microphysics and the effective radiative forcing due to aerosol‐cloud interactions (ERFaci) contribute to some of the largest uncertainties in general circulation models (GCMs) and are closely interrelated. This study shows that a sophisticated, two‐moment prognostic precipitation scheme can simultaneously represent both warm rain characteristics consistent with satellite observations and a realistic ERFaci magnitude, thus reconciling compensating errors between precipitation microphysics and ERFaci that are common to many GCMs. The enhancement of accretion from prognostic precipitation and accretion‐driven buffering mechanisms in scavenging processes are found to be responsible for mitigating the compensating errors. However, single‐moment prognostic precipitation without the explicit prediction of raindrop size cannot capture observed warm rain characteristics. Results underscore the importance of using a two‐moment representation of both clouds and precipitation to realistically simulate precipitation‐driven buffering of the cloud response to aerosol perturbations.
Advances in Modern Capacitive ECG Systems for Continuous Cardiovascular Monitoring

The technique of capacitive electrocardiography (cECG) is very promising in a flexible manner. Already integrated into several everyday objects, the single lead cECG system has shown that easy-to-use measurements of electrocardiograms are possible without difficult preparation of the patients. Multi-channel cECG systems enable the extraction of ECG signals even in the presence of coupled interferences, due to the additional redundant information. Thus, this paper presents challenges for electronic hardware design to build on developments in recent years, going from the one-lead cECG system to multi-channel systems in order to provide robust measurements - e.g. even while driving an automobile.
Quality Assessment of Root Canal Treatment Performed by Dental Students at Western University , Thailand

Dental students should have quality to perform RCT efficiently. The assessment root canal treatment (RCT) performed by the dental students is important to improve the clinical skill and dental education. The objective of this study was to access the quality of RCT performed by undergraduate dental students in Faculty of Dentistry, Western University, Thailand. A retrospective was conducted at Faculty of Dentistry, Western University, Thailand to access the RCT performed by undergraduate students. After obtaining the ethical approval, the study was conducted from September till December 2017. Intraoral periapical radiographs of 120 patients (a total of 134 teeth) who were treated with RCT were studied by one Endodontist. The evaluation criteria of the RCT were root canal obturation length, obturation density (homogeneity), and obturation taper. Microsoft Excel 2010 and SPSS version 20 (IBM Company, Chicago, USA) were used for the descriptive statistics and expressed as mean and percentage. Chi-Square test (for nominal data) was done to see the significant difference (P <0.001) among unacceptable, slightly acceptable, acceptable, perfect length of RCT. Pearson’s correlations will be done of length, density and taper of RCT with different teeth. For the length of RCT, the majority of the root canal filling had good length of filling with perfect length 66 (49.3%) and acceptable length 59 (44%) but only 2 (1.5%) showed unacceptable length. For the density of RCT, 66 (49.3%) had perfect density and 59 (44%) had acceptable density of root canal filling but only 4 (3%) showed unacceptable density. For the taper of RCT, majority 121 (90.3%) showed perfect, 11 (8.2%) showed acceptable and 2 (1.5%) showed unacceptable. Finally, of 134 root canal treated teeth, 3 (2.24%) had unacceptable and slightly acceptable quality, 30 (22.39%) had treatment of acceptable quality, and 98 (78.13%) teeth had perfectly acceptable quality. The quality of RCT performed by undergraduate students in Western University, Thailand was satisfactory to good. Still, to obtain more better results, emphasis can be given on the technical quality of RCT. Clinical article (J Int Dent Med Res 2018; 11(1): pp. 21-26)
Super-X divertors and high power density fusion devices

The Super-X Divertor (SXD), a robust axisymmetric redesign of the divertor magnetic geometry that can allow a fivefold increase in the core power density of toroidal fusion devices, is presented. With small changes in poloidal coils and currents for standard divertors, the SXD allows the largest divertor plate radius inside toroidal field coils. This increases the plasma-wetted area by 2–3 times over all flux-expansion-only methods (e.g., plate near main X point, plate tilting, X divertor, and snowflake), decreases parallel heat flux and hence plasma temperature at plate, and increases connection length by 2–5 times. Examples of high-power-density fusion devices enabled by SXD are discussed; the most promising near-term device is a 100 MW modular compact fusion neutron source “battery” small enough to fit inside a conventional fission blanket.

We consider a monopolist who sells identical objects of common but unknown value in a herding-prone environment. Buyers make their purchasing decisions sequentially, and rely on a private signal as well as previous buyers’ actions to infer the common value of the object. The model applies to a variety of cases, such as the introduction of a new product or the sale of licenses to use a patent. We characterize the monopolist’s optimal pricing strategy and its implications for the temporal pattern of prices and for herding. The analysis is performed under alternative assumptions about observability of prices. We find that when previous prices are observable, herding may but need not arise. In contrast, herding arises immediately when previous prices are unobservable and the seller’s equilibrium strategy is a pure Markov strategy. While the possibility of social learning is present in the first case, it is absent in the second. Finally, we examine the seller’s incentive to manipulate the buyers’ evaluation of the object when buyers are naive. Using secret discounts the seller successfully interferes with social learning, and herding occurs in finite time. JEL Classification: D8, D42.
Delay activity dynamics: task dependent time encoding and low dimensional trajectories

Our decisions often depend on multiple sensory experiences separated by time delays. The brain can remember these experiences (working memory) and, at the same time, it can easily estimate the timing between events, which plays a fundamental role in anticipating stimuli and planning future actions. To better understand the neural mechanisms underlying working memory and time encoding we analyze neural activity recorded during delays in four different experiments on non-human primates and we consider three classes of neural network models to explain the data: attractor neural networks, chaotic reservoir networks and recurrent neural networks trained with backpropagation through time. To disambiguate these models we propose two analyses: 1) decoding the passage of time from neural data, and 2) computing the cumulative dimensionality of the neural trajectory as it evolves over time. Our analyses reveal that time can be decoded with high precision in tasks where timing information is relevant and with lower precision in tasks where it is irrelevant to perform the task, suggesting that working memory need not rely on constant rates around a fixed activity pattern. In addition, our results further constrain the mechanisms underlying time encoding as we show that the dimensionality of the trajectories is low for all datasets. Consistent with this, we find that the linear “ramping” component of each neuron’s firing rate strongly contributes to the slow timescale variations that make decoding time possible. We show that these low dimensional ramping trajectories are beneficial as they allow computations learned at one point in time to generalize across time. Our observations constrain the possible models that explain the data, ruling out simple attractor models and randomly connected recurrent networks (chaotic reservoir networks) that vary on relatively fast timescales, but agree with recurrent neural network models trained with backpropagation through time. Our results demonstrate a powerful new tool for studying the interplay of temporal processing and working memory by objective classification of electrophysiological activity.
Predictors of Academic Achievement: The Effects of Demographic and Psychosocial Factors.

This study examined the effect of specified demographic and psychological variables on the academic achievement of high school students from urban and rural settings (n=177) . Psychosocial variables considered in this study were familism (perceived closeness of the family), perceived discrimination, time management, and home and school factors. Results provide information on the predictive factors associated with academic achievement among high school students (R square=.32) . The significant psychosocial predictors were advance program placement, economic condition, time management (i.e., as related to studying or doing homework), depression scale, parent-child conflict scale, and school location. Support for continued use of measures of psychosocial factors in the study of predictors of academic achievement was established. Implications for theory, practice, and future research are discussed.

A Collaborative Method for Agile Knowledge Management in Public Administrations

Knowledge has been and is still a major government’s resource. In this paper we present a collaborative methodology for implementing agile knowledge management programs in public administrations. The SAKE KM methodology is modular, supports all phases of the knowledge management programme, from strategic design to evaluation, and is based on the semantic annotation of the public administrations’ knowledge sources for easy information manipulation and retrieval. We also present our work towards the development of a knowledge management evaluation framework that employs as core axes the three primary measures of performance for government in the conduct of the determinative decision making: cost, quality and accountability.
Development of Barley Cultivars with Resistance to Scald (Rhynchosporium secalis (Oud.) Davis) in Japan

Hokuriku district in Japan is a major producing area of six-rowed barley, which is mainly consumed as pearled grain. However, the barley cultivated in this region has been damaged by scald, and commercial scald-resistant cultivars need to be developed. The influence of scald on yield reduction (previously addressed in many reports) and on pearled-grain quality was investigated. The whiteness of pearled grain, which is the most important quality in pearled barley, was not affected, but the pearling time tended to increase with the incidence of disease. Appropriate methods to evaluate resistance or susceptibility of cultivars in breeding programs were considered. Artificial inoculation in seedlings is not adequate to determine the resistance of cultivars because an outbreak of the disease has at times occurred after the heading stage. A field test with a source of infection, i.e., scattering leaves that were badly infected by prior inoculation of scald, accelerated the incidence and prevalence of the disease. When the source of infection was applied before the winter snows, it was especially effective in spreading the disease. The field test helped to determine resistant cultivars and breeding lines that inhibited the incidence of scald after the heading stage, although the occurrence of scald fluctuated according to weather conditions. Most Japanese commercial cultivars are highly susceptible in the field, whereas some foreign cultivars exhibit resistance to the dominant race of scald in Hokuriku district. We analyzed the resistance of “Brier” and showed that it was possibly controlled by one dominant gene at the heading stage, an observation that was in agreement with previous reports. On the other hand, three recessive genes are expected to confer resistance at the grain-filling stage. The heritability of resistance at the grainfilling stage was high, which means it is relatively easy to select resistant individuals in a breeding program even if it is controlled by several genes.
