TL;DR: The life histories and future trajectories of individuals and groups were largely neglected by early sociological research as discussed by the authors, and the life course perspective is perhaps the pre-eminent theoretical orientation in the study of lives.
Abstract: Today, the life course perspective is perhaps the pre-eminent theoretical orientation in the study of lives, but this has not always been the case. The life histories and future trajectories of individuals and groups were largely neglected by early sociological research. In the pioneering study, The Polish Peasant in Europe and America (1918-1920), W. I. Thomas (with Florian Znaniecki) first made use of such histories and trajectories and argued strongly that they be investigated more fully by sociologists. By the mid-1920s, Thomas was emphasizing the vital need for a “longitudinal approach to life history” using life record data (Volkart, 1951, p. 593). He advocated that studies investigate “many types of individuals with regard to their experiences and various past periods of life in different situations” and follow “groups of individuals into the future, getting a continuous record of experiences as they occur.” Though this advice went unheeded for decades, Thomas’s early recommendations anticipated study of the life course and longitudinal research that has become such a central part of modern sociology and other disciplines.

TL;DR: In this article, specific risk facets were operationalized, integrated, and empirically tested within the Technology Acceptance Model resulting in a proposed e-services adoption model, which indicated that adoption is adversely affected primarily by performance-based risk perceptions, and perceived ease of use of the e-service reduced these risk concerns.
Abstract: Internet-delivered e-services are increasingly being made available to consumers; however, little is known about how consumers evaluate them for potential adoption. Past Technology Adoption Research has focused primarily on the positive utility gains attributable to system adoption. This research extends that approach to include measures of negative utility (potential losses) attributable to e-service adoption. Drawing from Perceived Risk Theory, specific risk facets were operationalized, integrated, and empirically tested within the Technology Acceptance Model resulting in a proposed e-services adoption model. Results indicated that e-services adoption is adversely affected primarily by performance-based risk perceptions, and perceived ease of use of the e-service reduced these risk concerns. Implications of integrating perceived risk into the proposed e-services adoption model are discussed.

TL;DR: In this paper, a critical pedagogy of place is proposed, which seeks the twin objectives of decolonization and re-habitation through synthesizing critical and place-based approaches.
Abstract: Taking the position that “critical pedagogy” and “place-based education” are mutually supportive educational traditions, this author argues for a conscious synthesis that blends the two discourses into a critical pedagogy of place. An analysis of critical pedagogy is presented that emphasizes the spatial aspects of social experience. This examination also asserts the general absence of ecological thinking demonstrated in critical social analysis concerned exclusively with human relationships. Next, a discussion of ecological place-based education is offered. Finally, a critical pedagogy of place is defined. This pedagogy seeks the twin objectives of decolonization and “reinhabitation” through synthesizing critical and place-based approaches. A critical pedagogy of place challenges all educators to reflect on the relationship between the kind of education they pursue and the kind of places we inhabit and leave behind for future generations.

TL;DR: In this article, the authors report the development and validation of a parsimonious, generalizable scale that measures the hedonic and utilitarian dimensions of consumer attitudes toward product categories and different brands within categories.
Abstract: This article reports the development and validation of a parsimonious, generalizable scale that measures the hedonic and utilitarian dimensions of consumer attitudes toward product categories and different brands within categories. The hedonic/utilitarian (HED/UT) scale includes ten semantic differential response items, five of which refer to the hedonic dimension and five of which refer to the utilitarian dimension of consumer attitudes. The authors conducted six studies to establish the unidimensionality, reliability, and validity of the two HED/UT subscales. In reaching the final scale, the authors also develop and implement a unique process of paring down a psychometrically sound but otherwise too large set of items. Nomological validity is established by replacing a typical, one-dimensional attitude toward the brand measure with the hedonic and utilitarian dimensions in a central route processing model. Results suggest that the hedonic and utilitarian constructs are two distinct dimensions o...

TL;DR: The Infant Behavior Questionnaire-Revised (IBQ-R) as discussed by the authors was developed to measure parent-reported measures of infant temperament, including nine new scales and minor modifications of the seven scales of the IBQ.
Abstract: This study describes a revision of a widely used parent-report measure of infant temperament, the Infant Behavior Questionnaire (IBQ; Rothbart, 1981 ). A rationally derived instrument was developed that included nine new scales and minor modifications of the seven scales of the IBQ. Parents of 360 infants, equally distributed over three age groups: 3–6 months; 6–9 months; and 9–12 months of age, participated. Conceptual and item analyses provided support for 14 of the 16 proposed scales, demonstrating satisfactory internal consistency. Inter-rater reliability was evaluated, with evidence of moderate agreement between primary and secondary caregivers. Monomethod discriminant validity was demonstrated through an examination of correlations among the Infant Behavior Questionnaire—Revised (IBQ-R) scale scores. Results of the factor analytic procedure were consistent with three broad dimensions of Surgency/Extraversion, Negative Affectivity, and Orienting/Regulation. Developmental and gender differences were also noted for a number of the IBQ-R scales. Specifically, older infants received higher scores on Approach, Vocal Reactivity, High Intensity Pleasure, Activity, Perceptual Sensitivity, Distress to Limitations, and Fear, whereas younger infants’ scores were higher for Low Intensity Pleasure, Cuddliness/Affiliation, and Duration of Orienting. Male infants obtained higher scores on Activity and High Intensity Pleasure, and female infants were rated higher on the Fear scale.

TL;DR: The authors provide educators at all levels with a theoretical rationale for place-conscious education; they also discuss pedagogical pathways, and institutional challenges, to placeconsciousness, and conclude with an analysis of the possibilities for placeconscious education in an era that defines institutional accountability by standards and testing.
Abstract: This article provides educators at all levels with a theoretical rationale for place-conscious education; it also discusses pedagogical pathways, and institutional challenges, to place-consciousness. Drawing on insights from phenomenology, critical geography, bioregionalism, ecofeminism, and other place-conscious traditions, the author gathers diverse perspectives on “place” to demonstrate the profoundly pedagogical nature of human experience with places. Five “dimensions of place” are described that can shape the development of a socio-ecological, place-conscious education: (a) the perceptual, (b) the sociological, (c) the ideological, (d) the political, and (e) the ecological. After discussing these, the author reframes several place-conscious educational traditions. The article concludes with an analysis of the possibilities for place-conscious education in an era that defines institutional accountability by standards and testing.

TL;DR: Using relativistic density functional calculations, it is found that Au20 possesses a tetrahedral structure, which is a fragment of the face-centered cubic lattice of bulk gold with a small structural relaxation, which suggests that the Au20 cluster should be highly stable and chemically inert.
Abstract: Photoelectron spectroscopy revealed that a 20-atom gold cluster has an extremely large energy gap, which is even greater than that of C60, and an electron affinity comparable with that of C60. This observation suggests that the Au20 cluster should be highly stable and chemically inert. Using relativistic density functional calculations, we found that Au20 possesses a tetrahedral structure, which is a fragment of the face-centered cubic lattice of bulk gold with a small structural relaxation. Au20 is thus a unique molecule with atomic packing similar to that of bulk gold but with very different properties.

TL;DR: Analysis of the fat-reducing gene inactivations in insulin, serotonin and tubby signalling mutants of C. elegans, which have increased body fat, identifies a core set of fat regulatory genes as well as pathway-specific fat regulators.
Abstract: Regulation of body fat storage involves signalling between centres that regulate feeding in the brain and sites of fat storage and use in the body1,2. Here we describe an assay for analysing fat storage and mobilization in living Caenorhabditis elegans. By using RNA-mediated interference (RNAi)3,4 to disrupt the expression of each of the 16,757 worm genes, we have systematically screened the C. elegans genome for genes necessary for normal fat storage. We identify 305 gene inactivations that cause reduced body fat and 112 gene inactivations that cause increased fat storage. Analysis of the fat-reducing gene inactivations in insulin, serotonin and tubby signalling mutants of C. elegans, which have increased body fat, identifies a core set of fat regulatory genes as well as pathway-specific fat regulators. Many of the newly identified worm fat regulatory genes have mammalian homologues, some of which are known to function in fat regulation. Other C. elegans fat regulatory genes that are conserved across animal phylogeny, but have not previously been implicated in fat storage, may point to ancient and universal features of fat storage regulation, and identify targets for treating obesity and its associated diseases.
TL;DR: More studies are needed to connect the suspected mechanisms underlying both classes of hypotheses with quantitative changes in amphibian population sizes and species numbers, and to identify the hypotheses and conditions under which the various causes operate alone or together.
Abstract: Reports of malformed amphibians and global amphibian declines have led to public concern, particularly because amphibians are thought to be indicator species of overall envi- ronmental health. The topic also draws scientific attention because there is no obvious, simple answer to the question of what is causing amphi- bian declines? Complex interactions of several anthropogenic factors are probably at work, and understanding amphibian declines may thus serve as a model for understanding species declines in general. While we have fewer answers than we would like, there are six leading hypotheses that we sort into two classes. For class I hypotheses, alien species, over-exploitation and land use change, we have a good understanding of the ecological mechanisms underlying declines; these causes have affected amphibian populations negatively for more than a century. However, the question remains as to whether the magnitude of these negative effects increased in the 1980s, as scientists began to notice a global decline of amphibians. Further, remedies for these problems are not simple. For class II hypotheses, global change (including UV radiation and global climate change), contaminants and emerging infectious diseases we have a poor, but improving under- standing of how each might cause declines. Class II factors involve complex and subtle mechanistic underpinnings, with probable interactions among multiple ecological and evolutionary variables. They may also interact with class I hypotheses. Suspected mechanisms associated with class II hypotheses are relatively recent, dating from at least the middle of the 20th century. Did these causes act independently or in concert with pre- existing negative forces of class I hypotheses to increase the rate of amphibian declines to a level that drew global attention? We need more studies that connect the suspected mechanisms underlying both classes of hypotheses with quantitative changes in amphibian population sizes and species numbers. An important step forward in this task is clari- fying the hypotheses and conditions under which the various causes operate alone or together.
TL;DR: In this paper, the authors investigate whether institutional investors vote with their feet when dissatisfied with a firm's management by examining changes in equity ownership around forced CEO turnover and find that aggregate institutional ownership and the number of institutional investors decline in the year prior to forcing CEO turnover.
TL;DR: Overall, the research suggests that many neuropsychological tests have a moderate level of ecological validity when predicting everyday cognitive functioning, and the strongest relationships were noted when the outcome measure corresponded to the cognitive domain assessed by the neuroPsychological tests.
Abstract: Evaluating the ecological validity of neuropsychological tests has become an increasingly important topic over the past decade. In this paper, we provide a comprehensive review of the research on the ecological validity of neuropsychological tests, as it pertains to everyday cognitive skills. This review is presented in the context of several theoretical issues facing ecological validity research. Overall, the research suggests that many neuropsychological tests have a moderate level of ecological validity when predicting everyday cognitive functioning. The strongest relationships were noted when the outcome measure corresponded to the cognitive domain assessed by the neuropsychological tests. Several other factors that may moderate the degree of ecological validity established for neuropsychological tests are in need of further exploration. These factors include the effects of the population being tested, the approach utilized (verisimilitude vs. veridicality), the person completing the outcome measure (significant other vs. clinician), illness severity, and time from injury until evaluation. In addition, a standard measurement of outcome for each cognitive domain is greatly needed to allow for comparison across studies.
TL;DR: By probing the fluorescence lifetime of the single flavin on a photon-by-photon basis, the variation of flavin-tyrosine distance over time is observed, suggesting the existence of multiple interconverting conformers related to the fluctuating catalytic reactivity.
Abstract: Electron transfer is used as a probe for angstrom-scale structural changes in single protein molecules. In a flavin reductase, the fluorescence of flavin is quenched by a nearby tyrosine residue by means of photo-induced electron transfer. By probing the fluorescence lifetime of the single flavin on a photon-by-photon basis, we were able to observe the variation of flavin-tyrosine distance over time. We could then determine the potential of mean force between the flavin and the tyrosine, and a correlation analysis revealed conformational fluctuation at multiple time scales spanning from hundreds of microseconds to seconds. This phenomenon suggests the existence of multiple interconverting conformers related to the fluctuating catalytic reactivity.
TL;DR: In this paper, the authors conceptualized and developed a scale to measure individual differences in the centrality of visual product aesthetics (CVPA), defined as the level of significance that visual aesthetics hold for a particular consumer in his/her relationship with products.
Abstract: This research conceptualizes and develops a scale to measure individual differences in the centrality of visual product aesthetics (CVPA), defined as the level of significance that visual aesthetics hold for a particular consumer in his/her relationship with products. Three related dimensions of product aesthetics centrality emerged from the research: value, acumen, and response intensity. A series of eight studies provided evidence that the CVPA measure possesses satisfactory reliability and validity. Additionally, this research illuminates important differences between high and low CVPA consumers in product-design-related evaluations and behaviors and provides suggestions for future research employing the scale.
TL;DR: Although institutional investors have a preference for large capitalization stocks, over time they have shifted their preferences toward smaller, riskier securities as mentioned in this paper, and evidence also suggests that recent growth in institutional investment combined with this shift in preferences helps explain why markets in general and smaller stocks in particular, have exhibited greater firm-specific risk and liquidity.
Abstract: Although institutional investors have a preference for large capitalization stocks, over time they have shifted their preferences toward smaller, riskier securities. These changes in aggregate preferences have arisen primarily from changes in the preferences of each class of institution, rather than changes in the importance of different classes. Evidence also suggests that recent growth in institutional investment combined with this shift in preferences helps explain why markets in general, and smaller stocks in particular, have exhibited greater firm-specific risk and liquidity in recent years. Additional analyses suggest that institutional investors moved toward smaller securities because such securities offer "greener pastures." Copyright 2003, Oxford University Press.

TL;DR: It is shown that random objects (particularly random matrices) have "predictable" structures in the spectral domain and it develops a random matrix-based spectral filtering technique to retrieve original data from the dataset distorted by adding random values.
Abstract: Privacy is becoming an increasingly important issue in many data mining applications. This has triggered the development of many privacy-preserving data mining techniques. A large fraction of them use randomized data distortion techniques to mask the data for preserving the privacy of sensitive data. This methodology attempts to hide the sensitive data by randomly modifying the data values often using additive noise. We question the utility of the random value distortion technique in privacy preservation. We note that random objects (particularly random matrices) have "predictable" structures in the spectral domain and it develops a random matrix-based spectral filtering technique to retrieve original data from the dataset distorted by adding random values. We present the theoretical foundation of this filtering method and extensive experimental results to demonstrate that in many cases random data distortion preserve very little data privacy. We also point out possible avenues for the development of new privacy-preserving data mining techniques like exploiting multiplicative and colored noise for preserving privacy in data mining applications.
TL;DR: It is argued that to advance the knowledge of toxicant impacts on arthropods, the population growth rate approach should be widely adopted.
Abstract: New developments in ecotoxicology are changing the way pesticides and other toxicants are evaluated. An emphasis on life histories and population fitness through the use of demography, other measures of population growth rate, field studies, and modeling are being exploited to derive better estimates of pesticide impacts on both target and nontarget species than traditional lethal dose estimates. We review the state of the art in demographic toxicology, an approach to the evaluation of toxicity that uses life history parameters and other measures of population growth rate. A review of the literature revealed that 75 studies on the use of demography and similar measures of population growth rate in toxicology have been published since 1962. Of these 75 studies, the majority involved arthropods. Recent evaluations have indicated that ecotoxicological analysis based on population growth rate results in more accurate assessments of the impacts of pesticides and other toxicants because measures of population growth rate combine lethal and sublethal effects, which lethal dose/concentration estimates (LD/LC50) cannot do. We contend that to advance our knowledge of toxicant impacts on arthropods, the population growth rate approach should be widely adopted.
TL;DR: It is found that in the most common experimental circumstances, using micron-sized polystyrene or silica beads, absorption of the laser light in the solvent around the trapped particle, not in the particle itself, is the most important contribution to heating.
TL;DR: Experimental and theoretical evidence is reported that small boron clusters prefer planar structures and exhibit aromaticity and antiaromaticity according to the Hückel rules, akin to planar hydrocarbons.
Abstract: An interesting feature of elemental boron and boron compounds is the occurrence of highly symmetric icosahedral clusters. The rich chemistry of boron is also dominated by three-dimensional cage structures. Despite its proximity to carbon in the periodic table, elemental boron clusters have been scarcely studied experimentally and their structures and chemical bonding have not been fully elucidated. Here we report experimental and theoretical evidence that small boron clusters prefer planar structures and exhibit aromaticity and antiaromaticity according to the Huckel rules, akin to planar hydrocarbons. Aromatic boron clusters possess more circular shapes whereas antiaromatic boron clusters are elongated, analogous to structural distortions of antiaromatic hydrocarbons. The planar boron clusters are thus the only series of molecules other than the hydrocarbons to exhibit size-dependent aromatic and antiaromatic behaviour and represent a new dimension of boron chemistry. The stable aromatic boron clusters may exhibit similar chemistries to that of benzene, such as forming sandwich-type metal compounds.
TL;DR: The development of Pseudomonas for the control of Pythium diseases in hydroponics and Pseudozyma flocculosa for theControl of powdery mildew by two Canadian research programs is presented.
Abstract: The controlled environment of greenhouses, the high value of the crops, and the limited number of registered fungicides offer a unique niche for the biological control of plant diseases. During the past ten years, over 80 biocontrol products have been marketed worldwide. A large percentage of these have been developed for greenhouse crops. Products to control soilborne pathogens such as Sclerotinia, Pythium, Rhizoctonia and Fusarium include Coniothyrium minitans, species of Gliocladium, Trichoderma, Streptomyces, and Bacillus, and nonpathogenic Fusarium. Products containing Trichoderma, Ampelomyces quisqualis, Bacillus, and Ulocladium are being developed to control the primary foliar diseases, Botrytis and powdery mildew. The development of Pseudomonas for the control of Pythium diseases in hydroponics and Pseudozyma flocculosa for the control of powdery mildew by two Canadian research programs is presented. In the future, biological control of diseases in greenhouses could predominate over chemical pesticides, in the same way that biological control of greenhouse insects predominates in the United Kingdom. The limitations in formulation, registration, and commercialization are discussed, along with suggested future research priorities.
TL;DR: In this paper, the effects of ethical climate on organizational commitment were investigated and it was shown that an ethical climate of benevolence has a positive relationship with organizational commitment while egoistic climate is negatively related to commitment.
Abstract: Although organizational commitment continues to interest researchers because of its positive effects on organizations, we know relatively little about the effects of the ethical context on organizational commitment. As such, we contribute to the organizational commitment field by assessing the effects of ethical climates (Victor and Cullen, 1987, 1988) on organizational commitment. We hypothesized that an ethical climate of benevolence has a positive relationship with organizational commitment while egoistic climate is negatively related to commitment. Results supported our propositions for both a benevolent climate and an egoistic climate. We also hypothesized that a principled climate is positively related to organizational commitment for professional workers but has no relationships for nonprofessional workers. Results supported this hypothesis.
TL;DR: The predicted SLY1 amino acid sequence is highly conserved among plants, indicating a key role in GA response, and suggests SCFSLY1-targeted degradation of RGA through the 26S proteasome pathway.
Abstract: The Arabidopsis SLY1 (SLEEPY1) gene positively regulates gibberellin (GA) signaling. Positional cloning of SLY1 revealed that it encodes a putative F-box protein. This result suggests that SLY1 is the F-box subunit of an SCF E3 ubiquitin ligase that regulates GA responses. The DELLA domain protein RGA (repressor of ga1-3) is a repressor of GA response that appears to undergo GA-stimulated protein degradation. RGA is a potential substrate of SLY1, because sly1 mutations cause a significant increase in RGA protein accumulation even after GA treatment. This result suggests SCFSLY1-targeted degradation of RGA through the 26S proteasome pathway. Further support for this model is provided by the observation that an rga null allele partially suppresses the sly1-10 mutant phenotype. The predicted SLY1 amino acid sequence is highly conserved among plants, indicating a key role in GA response.
TL;DR: Limits on WM function, either intrinsic or extrinsic, are predictive of a more impulsive decision-making style because they led to greater discounting of delayed monetary rewards.
Abstract: Decision making that favors short-term over long-term consequences of action, defined as impulsive or temporally myopic, may be related to individual differences in the executive functions of working memory (WM). In the first 2 experiments, participants made delay discounting (DD) judgments under different WM load conditions. In a 3rd experiment, participants high or low on standardized measures of impulsiveness and dysexecutive function were asked to make DD judgments. A final experiment examined WM load effects on DD when monetary rewards were real rather than hypothetical. The results showed that higher WM load led to greater discounting of delayed monetary rewards. Further, a strong direct relation was found between measures of impulsiveness, dysexecutive function, and discounting of delayed rewards. Thus, limits on WM function, either intrinsic or extrinsic, are predictive of a more impulsive decision-making style.
TL;DR: A better understanding of the function of these calmodulin target proteins should help in deciphering the Ca(2+)/calmodulin-mediated signal network and its role in plant growth, development and response to environmental stimuli.
TL;DR: Detailed examination demonstrated that in experimentally infected calves the majority of tissue-associated bacteria were adherent to mucosal epithelium within a defined region extending up to 5 cm proximally from the recto-anal junction, a novel tropism that may enhance dissemination both between animals and from animals to humans.
Abstract: Escherichia coli O157:H7 causes bloody diarrhea and potentially fatal systemic sequelae in humans. Cattle are most frequently identified as the primary source of infection, and E. coli O157:H7 generally colonizes the gastrointestinal tracts of cattle without causing disease. In this study, persistence and tropism were assessed for four different E. coli O157:H7 strains. Experimentally infected calves shed the organism for at least 14 days prior to necropsy. For the majority of these animals, as well as for a naturally colonized animal obtained from a commercial beef farm, the highest numbers of E. coli O157:H7 were found in the feces, with negative or significantly lower levels detected in lumen contents taken from the gastrointestinal tract. Detailed examination demonstrated that in these individuals the majority of tissue-associated bacteria were adherent to mucosal epithelium within a defined region extending up to 5 cm proximally from the recto-anal junction. The tissue targeted by E. coli O157:H7 was characterized by a high density of lymphoid follicles. Microcolonies of the bacterium were readily detected on the epithelium of this region by immunofluorescence microscopy. As a consequence of this specific distribution, E. coli O157:H7 was present predominately on the surface of the fecal stool. In contrast, other E. coli serotypes were present at consistent levels throughout the large intestine and were equally distributed in the stool. This is a novel tropism that may enhance dissemination both between animals and from animals to humans. The accessibility of this site may facilitate simple intervention strategies.
TL;DR: Combined analyses of matK and other rapidly evolving DNA regions with available multigene data sets have strong potential to enhance resolution and internal support in deep level angiosperms phylogenetics and provide additional insights into angiosperm evolution.
Abstract: Plastid matK gene sequences for 374 genera representing all angiosperm orders and 12 genera of gymnosperms were analyzed using parsimony (MP) and Bayesian inference (BI) approaches. Traditionally, slowly evolving genomic regions have been preferred for deep-level phylogenetic inference in angiosperms. The matK gene evolves approximately three times faster than the widely used plastid genes rbcL and atpB. The MP and BI trees are highly congruent. The robustness of the strict consensus tree supercedes all individual gene analyses and is comparable only to multigene-based phylogenies. Of the 385 nodes resolved, 79% are supported by high jackknife values, averaging 88%. Amborella is sister to the remaining angiosperms, followed by a grade of Nymphaeaceae and Austrobaileyales. Bayesian inference resolves Amborella + Nymphaeaceae as sister to the rest, but with weak (0.42) posterior probability. The MP analysis shows a trichotomy sister to the Austrobaileyales representing eumagnoliids, monocots + Chloranthales, and Ceratophyllum + eudicots. The matK gene produces the highest internal support yet for basal eudicots and, within core eudicots, resolves a crown group comprising Berberidopsidaceae/Aextoxicaceae, Santalales, and Caryophyllales + asterids. Moreover, matK sequences provide good resolution within many angiosperm orders. Combined analyses of matK and other rapidly evolving DNA regions with available multigene data sets have strong potential to enhance resolution and internal support in deep level angiosperm phylogenetics and provide additional insights into angiosperm evolution.

TL;DR: In this paper, the authors investigated the dimensionality of counterproductive work behavior by examining the relationships between various counterproductive behaviors, including theft and related behavior, misuse of information, misuse of time and resources, unsafe behavior, poor attendance, poor quality work, alcohol use, drug use, inappropriate verbal actions, and inappropriate physical actions.
Abstract: The study investigated the dimensionality of counterproductive work behavior (CWB) by examining the relationships between various counterproductive behaviors. Utilizing a university alumni sample (N = 343), data was collected through both self-report and direct judgments of the likelihood of co-occurrence. Eleven categories of CWB were examined: (1) Theft and Related Behavior; (2) Destruction of Property; (3) Misuse of Information; (4) Misuse of Time and Resources; (5) Unsafe Behavior; (6) Poor Attendance; (7) Poor Quality Work; (8) Alcohol Use; (9) Drug Use; (10) Inappropriate Verbal Actions; and (11) Inappropriate Physical Actions. CWB items and categories were generally positively related. Multidimensional scaling analysis suggests that the CWB categories vary on two dimensions: an Interpersonal-Organizational dimension and a Task Relevance dimension.
