The purpose of this research is find out how the influence of firm size, free cash flow, leverage, and profitability on earnings management. The population used in this study uses hotel, tourism, and restaurant sub-sector service companies listed on the Indonesia Stock Exchange (IDX) in 2013-2020. The test results show that firm size and profitability have a positive effect on earnings management, this indicates that the larger the firm size and the level of profit, the greater the opportunity for management to practice earnings management. Free Cash Flow has a negative effect on earnings management, this shows that if the amount of free cash flow is low in a company, the higher earnings management practices will be. Leverage has no effect on earnings management, this shows that the level of leverage does not make management perform earnings management.

Published: August 2022

Contamination of drinking-water is a significant concern for public health throughout the world. Microbial hazards make the largest contribution to waterborne disease in developed and developing countries. Biofilm-producing bacteria were identified by the Congo Red Agar (CRA) method we obtained isolated of Aeromonas spp. formed Biofilm. the antibiotic resistance screening test to a number of antibiotics on Aeromonas spp. isolates. The results revealed that isolates of Aeromonas spp. have high resistance (100%) to Amoxicillin , Vancomycin and Cefoxitin. Whereas some isolates of Aeromonas spp. observed moderate resistance to Imipenem and Erythromycin. PCR to detected presence of fimH and papC genes in Aeromonas spp. that isolated from drinking water contain fimH gene and contain pap C. fimH was an important factor in cell control and bacterial persistence under stress conditions, and it contributed to virulence through a variety of mechanisms.
Azole Resistance in Candida Yeasts

Published: August 2022

Systemic fungal diseases and antifungal resistance represent a serious problem in human medicine and contribute to increased patient mortality. The most common causes of these diseases are opportunistic yeasts of the genus Candida. C. albicans is considered to be the main pathogen, together with C. glabrata, C. tropicalis, C. parapsilosis, and C. krusei. Azole antifungals predominate in the treatment of the systemic mycoses. For antifungal resistance in Candida spp. some genes and their mutations are responsible, the genes ERG11, CDR1, CDR2 and MDR1 being considered the most important. The main target of azole antifungals is the process of ergosterol synthesis. Due to ergosterol crucial functions and its unique structural properties, the synthesis of ergosterol and its individual steps represent the target of most clinically available antifungals. The biofilm appears to be a significant virulence factor of the yeast Candida spp. It allows hematogenous dissemination of cells, prevents the effect of antifungals on all cells during treatment and leads to a high level of antimicrobial resistance. The antifungal resistance in candidiasis often has a multifactorial origin, which must be considered in the treatment of systemic mycoses and in the development of new antifungals.
Weekday variations in short‐term contrarian profits in futures markets
Authors: Lin J.Barry , Onochie Joseph I. , Wolf Avner S. 
Published: July 2002

AbstractThis article documents and examines weekday patterns in short‐term contrarian profits in futures markets. The Lo and Mackinlay (1990) methodology is used to construct contrarian portfolios and to compute daily contrarian profits. Contrarian portfolios are formed using daily closing prices and are based on the previous day's performance relative to a benchmark. Contrarian profits are measured over subsequent half‐day intervals. The empirical results suggest that there are weekday patterns in short‐term contrarian profits in futures markets. On average, contrarian profits are largest on Fridays, followed by those on Wednesdays, and smallest on Mondays. For currency futures, however, contrarian profits are largest on Mondays and smallest on Fridays.
Stochastic Modeling of Affinity Adsorption
Authors: Hubble John 
Published: July 2002

AbstractA stochastic model is described that allows surface proximity and packing effects to be incorporated into predictions of adsorption kinetics and equilibrium of affinity adsorption. Equilibrium predictions show that, depending on conditions chosen, the results obtained for equilibrium conditions can exhibit either a Freundlich‐ or a Langmuir‐type relationship. Under conditions of surface density imposed adsorption constraints, the time taken for equilibrium to be reached increases as the “off” constant is decreased. This suggests that for resins having a high immobilized ligand density binding kinetics may be more highly limited by the “off” constant than by mass transfer limitations.
Mitochondrial Membrane Potential Selects Hybridomas Yielding High Viability in Fed‐Batch Cultures

Published: July 2002

AbstractPrior research (Follstad, B. D.; Wang, D. I. C.; Stephanopoulos, G. Mitochondrial membrane potential differentiates cells resistant to apoptosis in hybridoma cultures. Eur. J. Biochem. 2000, 267, 6534–6540.) identified mitochondrial membrane potential (MMP) as a marker of hybridoma subpopulations resistant to apoptosis caused by a variety of apoptosis inducers. In this study, we investigated the viability of hybridoma cell cultures inoculated with cells of varying MMP in regular fed‐batch operation. A hybridoma cell population was separated using FACS into subpopulations based on their mean mitochondrial membrane potential (MMP) as measured using the common mitochondrial stain, Rhodamine 123 (Rh123). These subpopulations showed dramatic differences in their apoptotic death kinetics. Fed‐batches inoculated with a high MMP subpopulation reached higher viable cell concentrations and viabilities that were maintained for prolonged periods of time relative to fed‐batches inoculated with low MMP subpopulations. These results underline the heterogeneous nature of hybridoma cell cultures and suggest that mitochondrial physiology is a critical parameter determining culture performance.
Ion Exchange Membrane Bioreactor for Selective Removal of Nitrate from Drinking Water: Control of Ion Fluxes and Process Performance
Authors: Velizarov Svetlozar , Crespo João G. , Reis Maria A. 
Published: July 2002

AbstractAn ion exchange membrane bioreactor (IEMB), consisting of a monoanion permselective membrane dialyzer coupled to a stirred anoxic vessel with an enriched mixed denitrifying culture, has been studied for nitrate removal from drinking water. The influence of nitrate and chloride concentrations on the selectivity of nitrate transport in the IEMB process was investigated. With appropriate dosing of chloride ions to the IEMB biocompartment, it was possible to regulate the net bicarbonate flux in the system, thus maintaining the bicarbonate concentration in the treated water at the desired level. The latter was not possible to achieve in Donnan dialysis, operated as a single process in which, besides the lower nitrate removal efficiency found, bicarbonate was co‐extracted together with nitrate from the polluted water stream. Residual carbon source (ethanol) and nitrite were not detected in the treated water produced in the IEMB system. With a concentration of nitrate in the polluted water three times higher than the maximum contaminant level of 50 mg L−1 allowed, the IEMB process was successfully operated for a period of 1 month before exceeding this limit.
The Influence of Restraint Immobilization Stress on the Concentration of Bioamines and Cortisol in Plasma of Pietrain and Duroc Pigs

Published: July 2002

SummaryForty‐five Duroc (recognized as not susceptible to stress) and 34 Pietrain (susceptible to stress) pigs were subjected to immobilization stress in a prone position for 5, 15, 30 and 60 min. Plasma concentrations of epinephrine (E), norepinephrine (NE), dopamine (DA) and cortisol (C) were determined in response to restraint stress. The concentrations of E, NE and DA were different between the two strains of pigs (some significant interactions); the highest response was seen after 5 min of stress. The concentration of plasma C increased with duration of stress and there was a significant interaction between strain of animals and the time of stress. Our data substantiate the use of E, NE, DA and C as indicators of stress in swine as early as 5 min after exposure to the stressor. It is also shown that stress‐susceptible Pietrain pigs had higher plasma concentrations of E, NE and DA than Duroc pigs.
A theoretical analysis of third-order nonlinear optical properties of linear polyenes and benzene
Authors: Pierce Brian M. 
Published: July 2002

An accurate and computationally tractable theoretical procedure for the calculation of the nonresonant, electronic components of the third-order molecular polarizabilities, γ(0;0,0,0), γ(−3ω;ω,ω,ω), and γ(−2ω;ω,ω,0), can be constructed. This procedure partitions γ into a σ-electron component (γσ) and a π-electron component (γπ). The γσ term is evaluated using the bond-additivity approximation; the γπ term is calculated using the semiempirical INDO all-valence-electron molecular orbital method combined with full single- and double-excitation configuration interaction (SDCI) of singlet π-electron configurations, and Orr and Ward’s sum-over-states expression for γ. The INDO-SDCI method is also used to calculate one- and two-photon spectroscopic properties of the 1ππ* states salient to γπ for the molecules of interest. It is shown that single-excitation CI alone is not sufficient for the calculation of γπ for linear polyenes and benzene. Calculations of the effect of chain length and conformation on the values of γ for ethylene, cis and trans linear polyenes, and benzene indicate that γ is strongly influenced by conjugation chain length. A simple relationship can be established between the calculated value of γπ(0;0,0,0) for the trans linear polyenes investigated and that for ethylene, the molecule with the solitary π-electron C–C bond: γπ(0;0,0,0)≂γπ(0;0,0,0)ethylene NC–C3, where NC–C=1,3,5,7, and NC–C is the total number of C=C and C–C bonds in the given polyene, i.e., the length of the π-bonding network. As γ increases with chain length, so does the ratio γπ/γ. Virtual electronic transitions involving excited π-electron states with extensive charge separation and double excited configurational character are important contributors to γπ for the linear polyenes and benzene. An approximation of γπ(0;0,0,0) for the linear polyenes can be written in terms of the linear π-electron polarizabilities for the ground state and 1 1Bu π-electron excited state. Although this
approximation is strictly applicable to the centrosymmetric linear polyenes, it does suggest a very interesting criterion for the selection of organic molecules with large third-order polarizabilities. Namely, the change in polarizability between the ground state and a strongly one-photon absorbing excited state is an important factor to consider when selecting candidate molecules.
Two- and three-dimensional numerical modeling of dispersion and mixing in shallow (tidal) waters
Authors: van Dam G. C. 
Published: July 2002

Two main mechanisms can be distinguished in the process of dispersion and mixing of dissolved or suspended matter in shallow waters: (1) vertical current shear and the accompanying vertical mixing and (2) spreading caused by the inhomogeneity and time dependence of the field of horizontal velocities. Both mechanisms have long been recognized and have been investigated by many researchers. The various studies usually concern only one of the two phenomena at a time. This is not necessarily a drawback from a theoretical viewpoint if care is taken that the values of parameters typical for one phenomenon, as derived from field data, are not significantly contaminated by effects caused by the other. In practice this type of error has been rather common. In several cases the existence of the other mechanism than the one described was entirely overlooked or at least neglected. There is an extensive range of time and length scales in which none of the two mechanisms has negligible influence. Most of the field data and many topics of interest are also in the range of simultaneous occurrence.
In order to determine the relative importance of the two mechanisms one needs a mathematical model in which the two phenomena are explicitly modeled in such a way that the entire range of several orders of magnitude is covered with good accuracy. This was established by a three-dimensional numerical model in which the dispersing matter was represented by discrete particles. In this way, no bound is set to spatial resolution; the scale range that can be covered is unbounded at either end. Extension at small scales only requires a consequent decrease of time step length. The second mechanism (horizontal inhomogeneity) can be simulated in two ways, by scaled random walk and by synthetic velocity fields. The first technique is the most economical. The second has the advantage that it is directly related to energy and velocity spectra; it has become more feasible by applying a shifting spectral window. The final results of the two techniques, measured as variances of particle clouds as functions of time, were virtually identical. It was found that only for very short and relatively long times (after instantaneous point release), the mechanism of the horizontal velocity structure prevails.
In the middle of the intermediate range, the vertical shear of the current is entirely dominant. In a basin like the North Sea this dominance occurs at horizontal length scales of a few kilometers and a time scale of a few hours to about one day, depending on the local vertical mixing rate and tidal energy. By adjusting the spectrum of the horizontal velocity structure to the rather extensive set of field data, a theoretical envelope was obtained from the model, enclosing the set of measured curves quite accurately. The resulting energy spectrum agrees well with estimates in the literature.
Pomak Borderlands: Muslims on the Edge of Nations
Authors: Neuburger Mary 
Published: July 2002

We contact the worldonly through our boundaries.Blaga DimitrovaIn a recent issue of the Bulgarian periodicalSega(Now) a reporter related an extraordinary tale of how various name-changing campaigns had marked the experience of a Bulgarian-speaking Muslim—hereafter “Pomak”—in the village of Bachkovo. The story began during the Balkan Wars in 1912–1913 when Hasan, the aforementioned Pomak from the Rhodope mountains of southern Bulgaria, was forced to change his name to Dragan as part of the wartime state campaign for Muslims with “Slavic origins” to “reclaim their Bulgarian names.” A change in politics at the beginning of World War I opened the door for Dragan to change his name back to Hasan; and so he did. In the late 1930s, however, he was again compelled to change his name back to Dragan, in line with theRodina(Homeland) directed name-changing campaigns, described in depth below. After the Communist takeover in 1944 Dragan was able, again, to change his name back to Hasan as wartime “Fascist” policy was reversed. But with the movement towards “national integration” in the 1960s Hasan was forced, again, to change his name back to Dragan. After the fall of Communism in Bulgaria in November 1989 “Dragan” again was allowed to change his name back to Hasan; and so he did. In his one lifetime this “Bulgarian” of Islamic faith, subject to the whims of the fickle and contested Bulgarian national project, changed his name six times. Admittedly, the Pomak's fate in Balkan history seems to be primarily as pawn in Bulgarian and other Balkan national rivalries and domestic designs. Pomak history is, more often than not, the story of the center looking to the margins and imposing its own designs. Having said that, these designs—generally driven by the dual forces of modernity and nationalism—were always subject to a spectrum of Pomak responses and strategies.
Failure of 5‐HT3receptors in regulation of ethanol‐induced ascorbic acid release in rat striatum

Published: July 2002

AbstractPrevious studies have shown that the serotonergic system was involved in ethanol‐induced striatal ascorbic acid release in rats. In the present study the possible role of 5‐HT 3 receptors in ethanol‐induced striatal ascorbic acid release was investigated in rats using 5‐HT 3 antagonists ondansetron, DAU 6215 and 5‐HT 3 agonist 2‐methyl‐serotonin. Extracellular level of ascorbic acid in the striatum was determined by means of in vivo microdialysis coupled to HPLC with electrochemical detection. Ethanol (3 g/kg, i.p.) induced a significant increase in ascorbic acid release. Ondansetron (0.2 and 2.0 mg/kg, i.p.), DAU 6215 (0.06, 0.12 and 0.24 mg/kg, i.p.) and 2‐methyl‐serotonin (250 μg/rat, i.c.v.), administered 10 minutes before 0.15 M NaCl or ethanol (3 g/kg, i.p.), affect neither the basal nor the ethanol‐induced ascorbic acid release in rat striatum. 2‐Methylserotonin, at a dose of 500 μg/rat, i.c.v., increased the basal, but did not affect the ethanol‐induced ascorbic acid release in rat striatum. However, ritanserin (1 mg/kg, s.c.), a 5‐HT 2 receptor antagonist, and BIMU 8 (40 μg/rat, i.c.v.), a 5‐HT 4 agonist, significantly antagonized ethanol‐induced ascorbic acid release. These results suggest that 5‐HT 3 receptors, which form a part of cation channels, may not be involved in ethanolinduced striatal ascorbic acid release.
Perception of aspiration and place of articulation of Cantonese initial stops by normal and sensorineural hearing‐impaired listeners
Authors: Y. H. Tsui Ida , Ciocca Valter 
Published: July 2002

AbstractThis study investigated the use of acoustic cues to the perception of aspiration and place of articulation of Cantonese initial stops by bilateral severely hearingimpaired (n =14) and normal‐hearing (n =14) adolescents. The stimuli were consonant‐vowel (CV) words spoken by two male speakers in which the initial consonants /p h, p, t h, t, k h, k/ were followed by the diphthong /i/. Subjects listened to the stimuli through a loudspeaker and chose the correct initial consonant among six choices. Three test conditions (short, medium and long voice onset time, or VOT) were prepared by increasing the VOT of unaspirated stops and by decreasing the VOT of aspirated stops. The results showed that the presence of aspiration noise was an important cue for normal listeners in the perception of aspiration, but not for hearing‐impaired listeners. Hearingimpaired listeners used formant transitions as the main cue to the perception of aspiration. VOT was a weak aspiration cue for both groups. In the perception of place of articulation, normal listeners appeared to rely mainly on formant transitions and release burst information rather than VOT. The recognition of place by hearing‐impaired listeners was at chance level for all the experimental stimuli, showing that these listeners were unable to use VOT, formant transitions or release burst information as cues to place.
