Audit Quality and Earnings Management In Indonesian Initial Public Offerings

This study examines the effect of audit quality on earnings management (as measured by discretionary current accruals) for Indonesian IPO firms. Earnings management is measured using current accruals, assuming that the manager has the flexibility and control to the current accruals than long-term accruals. The hypothesis predicts that Indonesian IPO firms with higher quality auditors engage in less earnings management in the periods prior to the IPO date. The sample consists of 62 firms making IPO between 2000 and 2006. The results show that high quality auditors are related to less earnings management in the periods prior to the IPO. Audit quality constrains the extent of earnings management for Indonesian IPO firms and provides more precise information that makes management has less incentive to manage earnings. Cash flows from operating activities and size of the firm have negative and significant effect on the level of current accruals. The study contributes to the literature that audit quality is an important determinant in earnings management practices for Indonesian IPO firms. DOI: 10.5901/mjss.2015. v6n5s5p223
Timid choices and bold forecasts: a cognitive perspective on risk taking

Decision makers have a strong tendency to consider problems as unique. They isolate the current choice from future opportunities and neglect the statistics of the past in evaluating current plans. Overly cautious attitudes to risk result from a failure to appreciate the effects of statistical aggregation in mitigating relative risk. Overly optimistic forecasts result from the adoption of an inside view of the problem, which anchors predictions on plans and scenarios. The conflicting biases are documented in psychological research. Possible implications for decision making in organizations are examined.
Using modified state surface approach to select parameter values in the Barcelona basic model

The Barcelona basic model (BBM) successfully explained many key features of unsaturated soils and received extensive acceptance. It is also one of the few elastoplastic constitutive models for unsaturated soils that have been implemented within finite element codes and applied to the analysis of real boundary value problems. The BBM was proposed in incremental forms according to theories of soil plasticity in which individual aspects of the isotropic virgin behavior are controlled by multiple parameters, whereas at the same time, a single parameter controls more than one aspect of soil behavior. Although a variety of methods have been recently developed for calibrating model parameters for elastoplastic soil models, at present, there are no well‐established, simple, and objective methods for selecting parameter values in the BBM from laboratory tests. This has been one of the major obstacles to the dissemination of this constitutive model beyond the research context.
The impact of tourism on subjective quality of life among Hungarian population

Nowadays the clarifi cation of the issues concerning subjective quality of life (QoL) enjoys a priority both in the dialogue between academic workshops and in political quarters responsible for the general state of society. The researchers – let them be the representatives of philosophy, psychology, sociology, geography or economics – are keen on fi nding the paths towards the sources of happiness, the ways to achieve subjective well-being, whilst the politicians are eager to trace what could be done in this sense by the power. There has been a wealth of literature on the relationship between the achievement of overall life satisfaction and sustainability of political power, notwithstanding only minor emphasis was put on the travelling behaviour of population as a factor of QoL and, consequently, of happiness. The governments of bourgeois democracies tend to cherish the sources of happiness stemming from leisure time spending – driven not so much by the desire to extend their power in time, rather prompted by moral responsibility for the well-being of society. Writings on the ways how policies might promote leisure time spending with travelling are many, but it is hardly known how these eff orts have been able to infl uence subjective QoL. In Hungary, the National Tourism Development Strategy (2005–2013) att ributes paramount importance to travelling of Hungarian population as one of the means to increase QoL – an eff ort unique even in international comparison. To att ain the objectives formulated in this document, and in order to yield a profi t for the society, the Tourism Unit of Ministry of Local Government and Regional Development (now Ministry of Local Government), together with the Hungarian National Tourist Offi ce and Geographical Research Institute Hungarian Academy of Sciences had requested the Hungarian Central Statistical Offi ce to perform a survey on the happiness markers related to travelling behaviour of the country’s population. This survey by questionnaires conducted in 11,500 households in the year 2007 has surfaced relationships between tourism and QoL hardly acknowledged heretofore. Putt ing the results of the survey considered representative with reference to the adult (18+) population of Hungary in the context of Hungarian and international literature, the present study provides an assessment of the tables of the data referring to the diff erent variables. A special emphasis is addressed to the general linkage between travels and overall life satisfaction and to the components of happiness off ered by travelling.
Progressive Music Activation Enhances Selective Attention in Healthy Older Adults and Alzheimer ’ s Disease Patients

Objectives: This study aims to demonstrate the effectiveness of progressive music activation to improve selective attention in patients diagnosed with Alzheimer’s disease (AD) and healthy older adults. Methods: 58 residents of senior centers or Alzheimer’s units aged over sixty-five participated in the study. Treatment group allocation was performed with permuted block randomization. Experimental group (Age, x̅ = 80,35; MMSE, x ̅ = 21,14) underwent 12 thirty-minute progressive music activation group sessions, conducted twice a week for six consecutive weeks. The rest of subjects (Age, x̅ = 79,41; MMSE, x̅ = 21,55) participated in a conversation group activity. To measure the efficacy of the therapy, we evaluated the general cognitive state of the participants by MMSE and a pre-post evaluation of their attention capacity applying an adapted version of the visual search task [1]. Results: We confirmed that the attention span of visual search improved significantly in persons who underwent the progressive music activation intervention. Conclusion: Progressive music activation could be considered as an enhancer of selective attention in patients with Alzheimer’s disease and in healthy older persons (HOA).
PRACTITIONERS ’ SECTION DEVELOPMENT OF SAFER MOLECULES THROUGH CHIRALITY

Many of the drugs currently used in medical practice are mixtures of enantiomers (racemates). Many a times, the two enantiomers differ in their pharmacokinetic and pharmacodynamic properties. Replacing existing racemates with single isomers has resulted in improved safety and/or efficacy profile of various racemates. In this review, pharmacokinetic and pharmacodynamic implications of chirality are discussed in brief, followed by an overview of some important chiral switches that have yielded safer alternatives. These include levosalbutamol, S-ketamine, levobupivacaine, S-zopiclone, levocetirizine, S-amlodipine, S-atenolol, S-metoprolol, S-omeprazole, S-pantoprazole and R-ondansetron. Few potential chiral switches under evaluation and some chiral switches that have not been successful are also discussed.
AN INVESTIGATION OF DEPRESSION IN GREEK THALASSAEMIC TEENAGERS

Objective: To explore characteristics of today’s Greek teenagers with thalassaemia, a hereditary disease, associated with the possibility of developing depression. Material and methods: Study sample consisted of 74 thalassaemic teenagers. Data collection was conducted using the “Children Depression Inventory” (CDI) and a questionnaire on teenage thalassaemic patients’ characteristics (socio-demographic; health condition) Results: In study thalassaemic teenagers, CDI Cronbach’s alpha was found to be 0.82. Most (65/74; 87%) had an average CDI score of 8. The vast majority (68/74) of study’s thalassaemic teenagers reported no body image changing. School absenteeism had a remarkable impact of 12% (sr 2 =0.12) on emotional mood of teenage thalassaemics. Relation of thalassaemic teenagers with their treating doctors and their mother’s workload interpreted 7% (sr 2 =0.07) and 7% (sr 2 =0.07) of CDI score, respectively. Conclusions: CDI proved to be reliable in Greek thalassaemic teenagers; and used for the first time to investigate their risk of developing depression. Only minimal depression was experienced by most teenage thalassaemics. Ranked in the order of importance, frequent school absenteeism, followed by poor relation with treating doctors as well as their working mother (caregiver) limited time for their care due to high workload, may deteriorate their emotional mood. It would be useful to plan actions to further reduce the small risk of developing depression as part of their healthy life.
Political Trust and Distrust in Switzerland: A Normative Analysis

Abstract: Based on data from a Swiss survey study (N = 769), this research investigated individual-level determinants of trust in political authorities from a social psychological perspective. The study demonstrates that individuals with a low level of education who feel materially at risk and politically powerlessness expressed the lowest levels of political trust. This relationship was explained with differential endorsement of normative beliefs. A mediation analysis reveals that normative perceptions of Swiss society as being threatened by immorality and growing social inequalities accounted for the effect of perceived material risk on political distrust. The rejection of a duty-based citizenship norm (voting), in turn, mediated the impact of political powerlessness on distrust. Political orientation was unrelated to political trust. These findings illustrate the cognitive underpinnings of political alienation and suggest that perceived lack of political agency and perceived risk of social declassification are key factors in understanding political distrust.
The origin of the atomic and molecular gas contents of early-type galaxies – I. A new test of galaxy formation physics

We study the atomic (H I) and molecular hydrogen (H2) contents of early-type galaxies (ETGs) and their gas sources using the GALFORM model of galaxy formation. This model uses a self-consistent calculation of the star formation rate, which depends on the H2 content of galaxies. We first present a new analysis of H I Parkes All-Sky Survey and ATLAS3D surveys, with special emphasis on ETGs. The model predicts H I and H2 contents of ETGs in agreement with the observations from these surveys only if partial ram pressure stripping of the hot gas is included, showing that observations of neutral gas in ‘quenched’ galaxies place stringent constraints on the treatment of the hot gas in satellites. We find that ≈90 per cent of ETGs at z = 0 have neutral gas contents supplied by radiative cooling from their hot haloes, 8 per cent were supplied by gas accretion from minor mergers that took place in the last 1 Gyr, while 2 per cent were supplied by mass-loss from old stars. The model predicts neutral gas fractions strongly decreasing with increasing bulge fraction. This is due to the impeded disc regeneration in ETGs, resulting from both active galactic nuclei feedback and environmental quenching by partial ram pressure stripping of the hot gas.
Effects of trust and psychological contract violation on authentic leadership and organizational deviance

Purpose - The aim of this article is to examine the relationships between authentic leadership and organizational deviance and to test the moderating effects of trust and psychological contract violation on that relationship. Design/methodology/approach - Data were collected from ten state universities in Turkey. The sample included 848 lecturers and their department chairs chosen randomly. Moderated hierarchical regression was used to examine the moderating roles of trust and psychological contract violation on the authentic leadership and organizational deviance relationship. Findings - The results show that authentic leadership is negatively and significantly correlated with organizational deviance. In addition, the results of the hierarchical multiple regression analyses support the moderating effects of employee trust and psychological contract violation with regard to the relationship between authentic leadership and organizational deviance. Practical implications - Given that authentic leadership is associated with valued organizational outcomes such as lower workplace deviance, higher followers' commitment, job satisfaction and citizenship behaviors, organizational efforts to foster authentic leadership should prove fruitful. Moreover, focusing on efforts to improve leader-follower relationship and to create a trust-based work environment could increase the likelihood that authentic leadership will lower level of workplace deviance. Originality/value - This study contributes to the research on authentic leadership and workplace deviance by showing that trust and psychological contract are relevant affect-related variables in determining the importance of authentic leadership perception to subordinate workplace deviance. Furthermore, by incorporating trust and psychological contract (for the first time), it is a response to recent calls for integration of authentic leadership, organizational deviance, trust and psychological contract literatures (Gardner
Alkaloid, Sterol and Triterpenoids from Glycosmis pentaphylla (Retz.) DC

Four compounds were isolated from the methanol extract of leaves of Glycosmis pentaphylla . The structures of the isolated compounds were solved as epi-oleanolic acid ( 1 ), β -amyrin ( 2 ), spinasterol ( 3 ) and arborinine ( 4 ) by extensive spectroscopic studies, including high field NMR analyses as well as co-TLC with authentic samples. This appeares to be the first report of their occurrence from Glycosmis species. DOI: http://dx.doi. org/10.3329/dujps.v13i2. 21887 Dhaka Univ. J. Pharm. Sci. 13(2): 115-118, 2014 (December)
PHYSICOCHEMICAL CHARACTERISTICS OF LINSEED OIL AND FLOUR

The objective of the study was to determine the chemical composition of a new linseed cultivar Zlocisty, characterized by a light seed coat. In this study, determinations were conducted for contents of: water and volatile substances, protein, fat, dietary fiber, acid detergent fiber (ADF) and neutral detergent fiber (NDF), pectins, starch, saccharides, methyl esters of fatty acids, peroxide number of fat, acidic and iodine values of fat, as well as for the percentage contribution of particular forms of lipids, sterols and tocopherols. An analysis of the chemical composition of linseed oil and flour demonstrated that both of these products may be valuable components of dietary supplements. The chemical composition of linseed oil was determined with special attention paid to bioactive substances from tocopherols, sterols and phospholipids. Based on the assayed chemical composition of flour, it appears that it might constitute a rich source of dietary fiber and zinc. The management of both of these semi-products affords the possibility of waste-free seed processing.
Nb-Ta fractionation in peraluminous granites: A marker of the magmatic-hydrothermal transition: REPLY

We important our original the issues In Ballouard et al. (2016), we propose that the decrease of the Nb/Ta ratios to <~5 in peraluminous granites “is the consequence of both fractional crystallization and sub-solidus hydrothermal alteration,” an interpretation challenged by Stepanov et al. (2016) who argue that low Nb/Ta ratios in peraluminous granites are better explained by magmatic fractionation and that the role of magmatic-hydrothermal processes is not significant. “post-magmatic”
Initial Soil Development Under Pioneer Plant Species in Metal Mine Waste Deposits

Mine waste materials are often inhospitable to plants due to extreme pH, high salinity, very low organic matter, elevated metal contents, and poor physical conditions. We investigated initial soil development in three study areas under different pioneer plant species in degraded landscapes left behind by past mining activities in southeast Spain. Soil pH, electrical conductivity, cation exchange capacity, total carbon, nitrogen, and sulfur were determined, as well as micromorphology, using 12 soil thin sections prepared from materials collected under vegetated and unvegetated sites. Soils are alkaline or highly alkaline, whereas other parameters substantially vary between sites (e.g., C:N = 9−149). pH of waste materials ranges from 6.2 to 7.9 and higher than soil pH, whereas electrical conductivity and gypsum contents were lower in soils than waste materials except for the Portman Bay site. Mine waste materials are dominated by platy/laminated microstructure, whereas incipient soils regardless of overlying pioneer species have granular structure of varying degrees of development. Roots of pioneer species break‐up the dense laminae of waste deposits and initiate preferential water flow through root channels. These channels encourage biological activities, and hence enhanced the accumulation of soil organic matter. The variables we investigated are useful to assess the formation of soils in inhospitable environments in mined areas. For instance, mechanical alteration of laminated waste deposits can be initiated by plowing to encourage preferential flow paths, hence soil development. Amendment of mine wastes with organic materials can stimulate biological activities to hasten the formation of granular soil microstructure common in productive ecosystems.
USING BALANCED SCORECARD IN MEASURING THE PERFORMANCE OF ONLINE BANKING: CULTIVATING STRATEGIC MODEL MAP IN FINANCIAL SECTOR-CASE OF BAHRAIN

The balanced scorecard is a system that focuses the efforts of employees, from different levels of the organization, towards achieving the company’s vision and strategic objectives. The purpose of this study is to use the balanced scorecard in measuring the performance of online banking and to focus on how to cultivate the strategic model map in the Bahraini financial sector. A qualitative method was used in this study, with the semi-structured interview questions classified into three main elements covering the financial sector: Strategic Vision and Mission, Strategic Objectives based on the four perspectives of Balanced Scorecard (BSC), and the Online Banking Performance Measurement System. Three local banks participated out of 11 conventional retail and Islamic retail banks in Bahrain. The study provides a basis for integrating measures of the BSC and offers guidelines for implementation of a performance management system and how to adjust the strategic model map to fill the existing gaps. A generic online banking strategy model map is formulated to show the strategic objectives and relevant measures of the scorecard perspectives. Representatives of major banks in Bahrain were interviewed to explore the ways in which they measure the performance of their online banking divisions. The study concludes by proving a list of recommendations to the financial sector.
Stellar Dynamics and Star Formation Histories of z ∼ 1 Radio-loud Galaxies

We investigate the stellar kinematics and stellar populations of 58 radio-loud galaxies of intermediate luminosities (L3 GHz > 1023 W Hz−1) at 0.6 < z < 1. This sample is constructed by cross-matching galaxies from the deep VLT/VIMOS LEGA-C spectroscopic survey with the VLA 3 GHz data set. The LEGA-C continuum spectra reveal for the first time stellar velocity dispersions and age indicators of z ∼ 1 radio galaxies. We find that z ∼ 1 radio-loud active galactic nucleus (AGN) occur exclusively in predominantly old galaxies with high velocity dispersions: σ* > 175 km s−1, corresponding to black hole masses in excess of 108 M⊙. Furthermore, we confirm that at a fixed stellar mass the fraction of radio-loud AGN at z ∼ 1 is five to 10 times higher than in the local universe, suggesting that quiescent, massive galaxies at z ∼ 1 switch on as radio AGN on average once every Gyr. Our results strengthen the existing evidence for a link between high black hole masses, radio loudness, and quiescence at z ∼ 1.
Fast and reliable method for measuring stellar differential rotation from photometric data

Context. Co-rotating spots at different latitudes on the stellar surface generate periodic photometric variability and can be useful proxies for detecting differential rotation (DR). This is a major ingredient of the solar dynamo, but observations of stellar DR are very sparse. Because the Kepler space telescope steadily collects more data, we are interested in detecting DR using photometric information of a star. Aims. The main goal of this paper is to develop a fast method for determining stellar DR from photometric data. Methods. We ran an extensive Monte Carlo simulation of differentially rotating spotted stars with very different properties to investigate the detectability of DR. For different noise levels the resulting light curves were prewhitened using Lomb-Scargle periodograms to derive parameters for a global sine fit to detect periodicities. Results. We show under which conditions DR can successfully be detected from photometric data, and in which cases the light curve provides insufficient or even misleading information on the stellar rotation law. In our simulations, the most significant period P1out is on average 2.4% shorter than the actual spot rotation-rate. This period was detected in 96.2% of all light curves. The signature of DR is a second period close to P1out in our model. For the noise-free case, we found such a period in 64.2% of all stars. Calculating the measured latitudinal shear of two distinct spots αout, and comparing this with the known original spot rotation-rates shows that the real value is on average 3.2% lower. Comparing the total equator-to-pole shear α to αout ,w e fi nd thatα is underestimated by 8.8%, especially the detection of DR for stars with α< 6% is challenging. Finally, we applied our method to four differentially rotating Kepler stars and found close agreement with results from detailed modeling. Conclusions. The method we developed is capable of measuring stellar rotation periods and detecting DR with relatively high accuracy and is suitable for large data sets. We will apply our analysis to more Kepler data in a forthcoming paper.
