TL;DR: This paper examined the effects of emotional labor on workers employed in the banking and hospital industries and found that performance of emotional labour does not have uniformly negative consequences for workers, as some accounts imply.
Abstract: Understanding the social-psychology effects of frontline service work requires attention to the emotional labor performed by incumbents of these positions. Using Hochschild's 1983 classification of jobs requiring emotional labor, this study examines the effects of emotional labor on workers employed in the banking and hospital industries. The results suggest that performance of emotional labor does not have uniformly negative consequences for workers, as some accounts imply. Instead, the effects of emotional labor are conditioned by workers' level of job autonomy and job involvement, and their self-monitoring abilities. The conditions under which emotional labor has negative and positive social-psychological consequences are discussed.

TL;DR: Molecular data strongly suggest that recurrent formation of polyploid species is the rule, rather than the exception, and that multiple origins were found to be frequent on a local geographic scale, as well as during a short span of time.
Abstract: During the past decade, molecular techniques have provided a wealth of data that have facilitated the resolution of several controversial questions in polyploid evolution. Herein we have focused on several of these issues: (1) the frequency of recurrent formation of polyploid species; (2) the genetic consequences of multiple polyploidizations within a species; (3) the prevalence and genetic attributes of autopolyploids; and (4) the genetic changes that occur in polyploid genomes following their formation. Molecular data provide a more dynamic picture of polyploid evolution than has been traditionally espoused. Numerous studies have demonstrated multiple origins of both allopolyploids and autopolyploids. In several polyploid species studied in detail, multiple origins were found to be frequent on a local geographic scale, as well as during a short span of time. Molecular data strongly suggest that recurrent formation of polyploid species is the rule, rather than the exception. In addition, molecul...

TL;DR: A map of the barley genome consisting of 295 loci was constructed, which includes 152 cDNA restriction fragment length polymorphism (RFLP), 114 genomic DNA RFLP, 14 random amplified polymorphic DNA (RAPD), five isozyme, two morphological, one disease resistance and seven specific amplicon polymorphism
Abstract: A map of the barley genome consisting of 295 loci was constructed. These loci include 152 cDNA restriction fragment length polymorphism (RFLP), 114 genomic DNA RFLP, 14 random amplified polymorphic DNA (RAPD), five isozyme, two morphological, one disease resistance and seven specific amplicon polymorphism (SAP) markers. The RFLP-identified loci include 63 that were detected using cloned known function genes as probes. The map covers 1,250 centiMorgans (cM) with a 4.2 cM average distance between markers. The genetic lengths of the chromosomes range from 124 to 223 cM and are in approximate agreement with their physical lengths. The centromeres were localized to within a few markers on all of the barley chromosomes except chromosome 5. Telomeric regions were mapped for the short (plus) arms of chromosomes 1, 2 and 3 and the long (minus) arm of chromosomes 7.

TL;DR: It is concluded that behavioral sensitization to cocaine is generally associated with an augmentation in extracellular dopamine in the ventral striatum, but that high doses of daily cocaine produce apparent tolerance to the augmentationIn extrace cellular dopamine during the early withdrawal period.
Abstract: Repeated administration of cocaine to rodents produces a progressive augmentation in motor activity known as behavioral sensitization. By using microdialysis in the ventral striatum, some studies have found that the development of behavioral sensitization is associated with a similar augmentation in dopamine release, while others have not. It was postulated that differences in doses and withdrawal periods may account for the discrepancies between studies. Rats were behaviorally sensitized to daily peripheral injections using two cocaine treatment regimens (15 mg/kg, i.p. x 5 d or 30 mg/kg, i.p. x 5 d). Using in vivo microdialysis in the ventral striatum, the effect of acute cocaine (15 mg/kg, i.p.) on extracellular dopamine content and motor behavior was examined at various times after discontinuing daily treatments. Twenty-four hours after discontinuing the low dose of daily cocaine, the increase in motor activity and extracellular dopamine elicited by an acute cocaine challenge was significantly elevated. In contrast, following the higher daily treatment regimen there was a significant augmentation in motor activity, but the increase in extracellular dopamine produced by cocaine was significantly reduced. When rats were challenged 10-14 d after discontinuing either dosage regimen of daily cocaine, the increase in both motor activity and extracellular dopamine was augmented. In general, the increase in extracellular dopamine by an acute cocaine challenge increased over time when rats were challenged between 1 and 22 d after discontinuing daily cocaine. Basal concentrations of extracellular dopamine were determined by measuring the in vivo flux of dopamine across the dialysis membrane, and there was no significant difference at 24 hr or 2 weeks following the last daily injection of saline or cocaine. It is concluded that behavioral sensitization to cocaine is generally associated with an augmentation in extracellular dopamine in the ventral striatum, but that high doses of daily cocaine produce apparent tolerance to the augmentation in extracellular dopamine during the early withdrawal period.

TL;DR: In this article, an empirical investigation of the importance of specialized assets and other unique characteristics of a firm in explaining the variance in capital structure across firms is presented, suggesting a strong link between strategy and capital structure.
Abstract: This paper presents an empirical investigation of the importance of specialized assets and other unique characteristics of a firm in explaining the variance in capital structure across firms. The results show that firm-specific effects contribute most to the variance in leverage, suggesting a strong link between strategy and capital structure.

TL;DR: In this article, the authors explored the generality of Gottfredson and Hirschi's theory by examining the link between low self-control and these imprudent behaviors.
Abstract: Gottfredson and Hirschi'sA General Theory of Crime contends that individual differences in involvement in criminal and analogous behavior are due largely to individual differences in the personality trait they call low self-control. Among the various behaviors considered analogous to crime are imprudent behaviors such as smoking, drinking, and gambling. This research explores the generality of Gottfredson and Hirschi's theory by examining the link between low self-control and these imprudent behaviors. The results are mixed. In support of the theory, the data reveal a modest but significant effect of a scale designed to capture the various components of low self-control on an index of imprudent behavior. A more detailed analysis, however, reveals that some of the components of low self-control, specifically those probably linked to low intelligence, detract from the scale's predictive power. In fact, one of the components, risk-seeking, is more predictive than the more inclusive scale. Furthermore, one of the imprudent acts, smoking, appears to be unaffected by low self-control. These contradictory findings suggest the need for theoretical refinements.

TL;DR: In this article, the authors explore work-family relations from the perspective of the emotion management performed by participants in both spheres, considering how work and family roles vary in the types and degrees of emotion management they require.
Abstract: This article explores work-family relations from the perspective of the emotion management performed by participants in both spheres. We extend previous discussions of emotion management by considering how work and family roles vary in the types and degrees of emotion management they require. We then explore the implications of this conception of work-family role variations in type and degree of emotion management for women's and men's work-family relations, paying particular attention to gender differences in work-family conflict and work-family role overload. The framework developed here highlights the need to examine variability in the emotion-management requirements of social roles, and it calls for attention to workers' multiple role involvements in studies of emotion management and their effects on individuals.

TL;DR: It is concluded that daily cocaine injections produce a transient alteration in the regulation of somatodendritic dopamine release, and these changes are not responsible for the long-term behavioral sensitization produced by repeated cocaine administration, but may be involved in the initiation of Behavioral sensitization.
Abstract: Cocaine was administered daily (15 mg/kg, i.p. x 1 d followed by 30 mg/kg, i.p. x 5 d) to produce behavioral sensitization. Using microdialysis in the ventral tegmental area and medial substantia nigra, the effect of repeated cocaine was examined on the extracellular levels of dopamine. One day after discontinuing repeated cocaine injections, an acute challenge with cocaine (15 mg/kg, i.p.) produced a significant elevation in extracellular dopamine compared to rats pretreated with daily saline (x6 d). The augmentation in extracellular dopamine persisted longer than the sensitized behavioral response. In contrast, 14 d after discontinuing daily cocaine, the increase in extracellular dopamine produced by an acute cocaine challenge was not augmented, although behavioral sensitization was present. In separate animals, the basal concentration of dopamine in the ventral tegmental area/medial substantia nigra was measured by determining the concentration of dopamine at which no net flux occurred across the dialysis membrane in vivo. One day after discontinuing daily treatments, the basal level of extracellular dopamine in the cocaine pretreated rats was significantly elevated over the level in saline- pretreated animals (1.3 nM vs. 0.8 nM). By 14 d after the last daily injection, the basal levels of dopamine were equivalent in cocaine- and saline-pretreated animals. It is concluded that daily cocaine injections produce a transient alteration in the regulation of somatodendritic dopamine release. While such changes are not responsible for the long-term behavioral sensitization produced by repeated cocaine administration, they may be involved in the initiation of behavioral sensitization.

TL;DR: This article used distinctions among foci and bases of commitment to develop four profiles of commitment, and examined the extent to which differences in these patterns predict other variables, including intent to quit, job satisfaction, prosocial organizational behaviors, and certain demographic and contextual variables.
Abstract: Prior research has demonstrated the importance of distinguishing among foci and bases of commitment. Foci of commitment are the individuals and groups to whom an employee is attached, and bases of commitment are the motives engendering attachment. This study uses distinctions among foci and bases of commitment to develop four profiles of commitment, and examines the extent to which differences in these patterns predict other variables. Cluster analysis of 440 employees suggests the following profiles: (1) The Locally Committed (employees who are attached to their supervisor and work group), (2) the Globally Committed (who are attached to top management and the organization), (3) the Committed (who are attached to both local and global foci), and (4) the Uncommitted (who are attached to neither local nor global foci). The profiles are differentially related to intent to quit, job satisfaction, prosocial organizational behaviors, and certain demographic and contextual variables. Implications of these findings for theory and practice are discussed.

TL;DR: By optimizing the intracavity dispersion compensation in a self-mode-locked Ti:sapphire laser, pulses of 10.95-fs duration are generated, which are shorter than has been possible with any other type of laser material to date.
Abstract: By optimizing the intracavity dispersion compensation in a self-mode-locked Ti:sapphire laser, we have generated pulses of 10.95-fs duration. Dispersion within the laser cavity is reduced by use of a short 4.5-mm highly doped Ti:sapphire crystal and fused-silica prisms. The output from the laser has an average power of as much as 500 mW, with a wavelength centered at 780 nm and a bandwidth of 62 nm. Our results demonstrate that the exceptionally broad bandwidth of Ti:sapphire can be utilized to generate pulses that, to our knowledge, are shorter than has been possible with any other type of laser material to date.

TL;DR: Quantitative trait locus (QTL) and QTL x environment (E) interaction effects for agronomic and malting quality traits were measured using a 123-point linkage map and multi-environment phenotype data from an F1-derived doubled haploid population of barley.
Abstract: Quantitative trait locus (QTL) and QTL x environment (E) interaction effects for agronomic and malting quality traits were measured using a 123-point linkage map and multi-environment phenotype data from an F1-derived doubled haploid population of barley (Hordeum vulgare). The QTL × E interactions were due to differences in magnitude of QTL effects. Highly significant QTL effects were found for all traits at multiple sites in the genome. Yield QTL peaks and support intervals often coincided with plant height and lodging QTL peaks and support intervals. QTL were detected in the vicinity of a previously mapped Mendelian maturity locus and known function probes forα- andβ-amylase genes. The average map density (9.6 cM) should be adequate for molecular marker-assisted selection, particularly since there were few cases of alternative favorable alleles for different traits mapping to the same or adjacent intervals.

TL;DR: It is proposed that behavioral sensitization arises from an alteration in the neural circuitry that subserves the translation of motivationally relevant stimuli into adaptive motor responses, and an enduring change in dopamine transmission may alter the functional state of the circuit to produce Behavioral sensitization.
Abstract: Behavioral sensitization to amphetamine-like psychostimulants is manifest as a progressive increase in drug-induced anxiety and paranoia which can culminate in psychopathologies, such as paranoid psychosis and panic attacks. Sensitization may also mediate the facilitation of drug relapse in addicts by increasing the reinforcing value of acute drug administration. The primary animal model for psychostimulant-induced psychopathologies involves repeated, non-contingent administration of drug to rodents, which can produce a progressive and enduring augmentation in motor activity and increased susceptibility to drug self-administration. Because of the mature literature implicating mesoaccumbens dopamine transmission in the acute motor and reinforcing effects of amphetamine-like stimulants, investigation into the neural basis of behavioral sensitization has focused on this projection. Over the last decade, with a few exceptions, the neurochemical and molecular literature that has emerged from this effort is replete with inconsistencies. In contrast, the presence of behavioral sensitization is a highly replicable event. It is proposed that behavioral sensitization arises from an alteration in the neural circuitry that subserves the translation of motivationally relevant stimuli into adaptive motor responses. The mesoaccumbens dopamine projection is embedded in this circuit and an enduring change in dopamine transmission may alter the functional state of the circuit to produce behavioral sensitization. However, combinations of alterations in other connections within the circuit can also support behavioral sensitization. The specific changes in the circuit that promote behavioral sensitization are under the control of experimental parameters, such as the drug employed, dosage regimen, withdrawal period and the presence of conditioning cues. Thus, the profile of neurochemical alterations observed after exposure to repeated psychostimulants may vary depending upon the experimental protocol and strain of animals, even though all laboratories report the presence of behavioral sensitization.

TL;DR: Large surficial offsets and a relatively short rupture length are consistent with seismological calculations of a high stress drop, which is in turn consistent with an apparently long recurrence interval for these faults.
Abstract: The Landers earthquake, which had a moment magnitude (M_w) of 7.3, was the largest earthquake to strike the contiguous United States in 40 years. This earthquake resulted from the rupture of five major and many minor right-lateral faults near the southern end of the eastern California shear zone, just north of the San Andreas fault. Its M_w 6.1 preshock and M_w 6.2 aftershock had their own aftershocks and foreshocks. Surficial geological observations are consistent with local and far-field seismologic observations of the earthquake. Large surficial offsets (as great as 6 meters) and a relatively short rupture length (85 kilometers) are consistent with seismological calculations of a high stress drop (200 bars), which is in turn consistent with an apparently long recurrence interval for these faults.

TL;DR: It is demonstrated that stimulation of NMDA receptors in the VTA and amygdala is necessary in the development of behavioral sensitization to cocaine.
Abstract: Systemic administration of N-methyl-D-aspartate (NMDA) antagonists prevents the development of behavioral sensitization to amphetamine-like psychostimulants. Pretreatment with the noncompetitive NMDA antagonist, MK-801, resulted in a dose-dependent blockade of behavioral sensitization to cocaine. However, pretreatment with the highest dose of MK-801 (0.25 mg/kg i.p.) alone inhibited the behavioral response to a subsequent cocaine challenge 24 hr later. The induction of behavioral sensitization is known to result, at least partly, from an action by psychostimulants in the ventral tegmental area (VTA). To determine whether the dose-dependent inhibition of behavioral sensitization to cocaine by NMDA antagonists resulted from receptor blockade in the VTA, rats were pretreated in the VTA with the MK-801 or the competitive NMDA antagonist, 3-(2-carboxypiperazine-4-yl) propyl-1-phosphonic acid, before systemically administered cocaine (30 mg/kg i.p.). Two to 3 days later rats were challenged with cocaine alone (15 mg/kg i.p.). Pretreatment with either NMDA antagonist into the VTA prevented the manifestation of behavioral sensitization. Intracranial pretreatment with MK-801 was also made into the nucleus accumbens and amygdala which have been implicated in psychostimulant-induced sensitization. Whereas MK-801 was without effect in the nucleus accumbens, when microinjected into the ventral amygdala it prevented the manifestation of behavioral sensitization to a cocaine challenge. The blockade of sensitization by MK-801 in the VTA was produced with a minimum effective dose of 0.01 nmol, whereas the minimum effective dose in the amygdala was 1.0 nmol. These data demonstrate that stimulation of NMDA receptors in the VTA and amygdala is necessary in the development of behavioral sensitization to cocaine.

TL;DR: It is concluded that under a wide range of conditions fluorescence parameters can be used to predict accurately and rapidly CO2 assimilation rates in maize.
Abstract: Analysis is made of the energetics of CO2 fixation, the photochemical quantum requirement per CO2 fixed, and sinks for utilising reductive power in the C4 plant maize. CO2 assimilation is the primary sink for energy derived from photochemistry, whereas photorespiration and nitrogen assimilation are relatively small sinks, particularly in developed leaves. Measurement of O2 exchange by mass spectrometry and CO2 exchange by infrared gas analysis under varying levels of CO2 indicate that there is a very close relationship between the true rate of O2 evolution from PS II and the net rate of CO2 fixation. Consideration is given to measurements of the quantum yields of PS II (φ PS II) from fluorescence analysis and of CO2 assimilation ( $$\phi _{CO_2 } $$ ) in maize over a wide range of conditions. The $${{\phi _{PSII} } \mathord{\left/ {\vphantom {{\phi _{PSII} } {\phi _{CO_2 } }}} \right. \kern- ulldelimiterspace} {\phi _{CO_2 } }}$$ ratio was found to remain reasonably constant (ca. 12) over a range of physiological conditions in developed leaves, with varying temperature, CO2 concentrations, light intensities (from 5% to 100% of full sunlight), and following photoinhibition under high light and low temperature. A simple model for predicting CO2 assimilation from fluorescence parameters is presented and evaluated. It is concluded that under a wide range of conditions fluorescence parameters can be used to predict accurately and rapidly CO2 assimilation rates in maize.

TL;DR: Since the last review on the Ca2+ messenger system in 1987, there has been tremendous progress in elucidating various aspects of Ca(2+) -signaling pathways in plants, including demonstration of signal-induced changes in cytosolic Ca2+, cal modulin and calmodulin-like proteins, and increased evidence in support of the role of inositol phospholipids in the Ca( 2+) - Signaling system.
Abstract: Environmental and hormonal signals control diverse physiological processes in plants. The mechanisms by which plant cells perceive and transduce these signals are poorly understood. Understanding biochemical and molecular events involved in signal transduction pathways has become one of the most active areas of plant research. Research during the last 15 years has established that Ca2+ acts as a messenger in transducing external signals. The evidence in support of Ca2+ as a messenger is unequivocal and fulfills all the requirements of a messenger. The role of Ca2+ becomes even more important because it is the only messenger known so far in plants. Since our last review on the Ca2+ messenger system in 1987, there has been tremendous progress in elucidating various aspects of Ca(2+) -signaling pathways in plants. These include demonstration of signal-induced changes in cytosolic Ca2+, calmodulin and calmodulin-like proteins, identification of different Ca2+ channels, characterization of Ca(2+) -dependent protein kinases (CDPKs) both at the biochemical and molecular levels, evidence for the presence of calmodulin-dependent protein kinases, and increased evidence in support of the role of inositol phospholipids in the Ca(2+) -signaling system. Despite the progress in Ca2+ research in plants, it is still in its infancy and much more needs to be done to understand the precise mechanisms by which Ca2+ regulates a wide variety of physiological processes. The purpose of this review is to summarize some of these recent developments in Ca2+ research as it relates to signal transduction in plants.

TL;DR: In this paper, color effects are shown to exhibit different patterns depending on the type of response examined, and these effects are described as a function of color wavelength, while the activation response engendered by color exhibits a U-shaped pattern across wavelengths.
Abstract: Prior research has typically grouped color effects into a single class of effects and has ignored situational aspects of consumer responses to color. In the present study, color effects are shown to exhibit different patterns depending on the type of response examined. Further, these effects are described as a function of color wavelength. Evaluative effects are most positive at the short wavelength (blue) end of the visible spectrum, while the activation response engendered by color exhibits a U-shaped pattern across wavelengths. Results of the study support the existence of these two distinct dimensions, and potential applications of the findings are discussed.

TL;DR: The Ethical Climate Questionnaire as discussed by the authors measures the ethical climates at individual and organizational levels of analysis, with 1,167 individuals tested across three surveys, and the results at the individual level have suggested strong support for the validity and reliability of the questionnaire.
Abstract: The Ethical Climate Questionnaire measures the ethical climates at individual and organizational levels of analysis. With 1,167 individuals tested across three surveys the results at the individual level have suggested strong support for the validity and reliability of the questionnaire However, given the limited number of organizations (n = 12) surveyed, the presence of organizational-level ethical climates remains contestable. This paper reports on the development of the Ethical Climate Questionnaire, includes the results of the latest survey, and contrasts these results with previous findings.

Abstract: An experimental study of alternatives to the current U.S. decennial census questionnaire shows that shortening the questionnaire and respondent-friendly questionnaire design improve response, whereas asking a potentially difficult and/or objectionable question, that is, social security number, lowers response. This national study of 17000 household addresses also desmonstrates that relatively high mail survey response can be achieved without addressing correspondence to individual names of residents

TL;DR: Theories explaining electroporation of the cell membrane and applications of the nonthermal PEF process are reviewed in this paper.
Abstract: Pulses of high voltage electric fields (PEF) are potentially a most important cold pasteurization/sterilization food preservation technique to replace or partially substitute for thermal processes. During the PEF process, lysis of micro-organisms is caused by irreversible structural changes in the membranes, leading to pore formation and destruction of the semipermeable barrier of the membrane. Theories explaining electroporation of the cell membrane and applications of the nonthermal PEF process are reviewed in this paper.

TL;DR: The gradual development of symptoms at 6 degrees C and other lines of evidence argue against a general collapse of membrane integrity as the cause of the lethal phenotype and indicate that the decrease in polyunsaturated membrane lipids may initially have relatively limited effects in disrupting cellular function.
Abstract: Mutants of Arabidopsis that contain reduced levels of polyunsaturated fatty acids showed growth characteristics at 22 degrees C that were very similar to wild type. By contrast, at 12 degrees C, the mutants failed to undergo stem elongation during reproductive growth although they produced normal flowers and fertile seeds. After transfer to 6 degrees C, rosette leaves of the mutants gradually died, and the plants were inviable. These different responses of the mutant plants at 12 degrees C and 6 degrees C suggest that distinct functions may be affected at these two temperatures. The gradual development of symptoms at 6 degrees C and other lines of evidence argue against a general collapse of membrane integrity as the cause of the lethal phenotype. Rather, they indicate that the decrease in polyunsaturated membrane lipids may initially have relatively limited effects in disrupting cellular function.

TL;DR: The biodynamic farms in the study had better soil quality than the neighboring conventional farms and were just as financially viable on a per hectare basis.
Abstract: Biodynamic farming practices and systems show promise in mitigating some of the detrimental effects of chemical-dependent, conventional agriculture on the environment. The physical, biological, and chemical soil properties and economic profitability of adjacent, commercial biodynamic and conventional farms (16 total) in New Zealand were compared. The biodynamic farms in the study had better soil quality than the neighboring conventional farms and were just as financially viable on a per hectare basis.

TL;DR: In this paper, an index tapping the frequency with which parents actively mediate children's interpretations of television messages is tested in a survey of 346 adolescents, which produces a reliable index which predicts skepticism, public affairs media use, and public affairs discussion.
Abstract: An index tapping the frequency with which parents actively mediate children's interpretations of television messages is tested in a survey of 346 adolescents. The measures produce a reliable index, which predicts skepticism, public affairs media use, and public affairs discussion. When tested along with family communication norms including concept orientation, socio orientation, and communication warmth, mediation remains a significant predictor. It is the only significant predictor among the variables tested for skepticism, in which the variance explained remains small.
