Business Process Retrieval Based on Behavioral Semantics

This paper develops a framework for retrieving business processes considering search requirements based on behavioral semantics properties; it presents a framework called "BeMantics" for retrieving business processes based on structural, linguistics, and behavioral semantics properties. The relevance of the framework is evaluated retrieving business processes from a repository, and collecting a set of relevant business processes manually issued by human judges. The "BeMantics" framework scored high precision values (0.717) but low recall values (0.558), which implies that even when the framework avoided false negatives, it prone to false positives. The highest pre- cision value was scored in the linguistic criterion showing that using semantic inference in the tasks comparison allowed to reduce around 23.6 % the number of false positives. Using semantic inference to compare tasks of business processes can improve the precision; but if the ontologies are from narrow and specific domains, they limit the semantic expressiveness obtained with ontologies from more general domains. Regarding the perform- ance, it can be improved by using a filter phase which indexes business processes taking into account behavioral semantics propertie

The gray matter structural connectome and its relationship to alcohol relapse: Reconnecting for recovery.

Gray matter (GM) atrophy associated with alcohol use disorders (AUD) affects predominantly the frontal lobes. Less is known how frontal lobe GM loss affects GM loss in other regions and how it influences drinking behavior or relapse after treatment. The profile similarity index (PSI) combined with graph analysis allows to assess how GM loss in one region affects GM loss in regions connected to it, ie, GM connectivity. The PSI was used to describe the pattern of GM connectivity in 21 light drinkers (LDs) and in 54 individuals with AUD (ALC) early in abstinence. Effects of abstinence and relapse were determined in a subgroup of 36 participants after 3 months. Compared with LD, GM losses within the extended brain reward system (eBRS) at 1-month abstinence were similar between abstainers (ABST) and relapsers (REL), but REL had also GM losses outside the eBRS. Lower GM connectivities in ventro-striatal/hypothalamic and dorsolateral prefrontal regions and thalami were present in both ABST and REL. Between-networks connectivity loss of the eBRS in ABST was confined to prefrontal regions. About 3 months later, the GM volume and connectivity losses had resolved in ABST, and insula connectivity was increased compared with LD. GM losses and GM connectivity losses in REL were unchanged. Overall, prolonged abstinence was associated with a normalization of within-eBRS connectivity and a reconnection of eBRS structures with other networks. The re-formation of structural connectivities within and across networks appears critical for cognitive-behavioral functioning related to the capacity to maintain abstinence after outpatient treatment

Contextualising over-engagement in work: towards a more global understanding of workaholism as an addiction

Purpose: Despite increasing empirical research into workaholism, no single definition or conceptualisation has emerged, and current understandings of workaholism are arguably problematic. The primary purpose of this paper is to clarify some of these issues, by defining and contextualising over-engagement in work that leads to severe negative consequences (i.e., workaholism) as a genuine behavioural addiction. Approach: By conceptualising work behaviours as manifestations of behavioural engagement and placing them on a continuum from withdrawal/under-engagement (e.g., persistent absenteeism) to over-engagement (e.g., work conflicting with all other activity), this paper argues that workaholism is an extreme negative aspect of behavioural engagement. It then examines the extent to which workaholism can be viewed as a genuine addiction by using criteria applied to other more traditional behavioural addictions (e.g., gambling addiction, exercise addiction), before briefly outlining an approach towards a more global understanding of workaholism. Findings: The framework presented here helps to contextualise over-engagement to work as a genuine addiction. It presents more comprehensive understanding of workaholism that takes into account the individual factors of the employee, situational factors of the working environment, and structural factors of the work activity itself. It provides theoretically derived links between workaholism and other work behaviours that can be empirically demonstrated. Practical implications: Viewing workaholism as an addiction that comprises extreme and prolonged behavioural over-engagement can be invaluable for promoting healthy work engagement. A clearer understanding of the underpinnings of workaholism can allow for a better assessment and management by practitioners. Originality/value: This paper is one the first to contextualise workaholism in relation to other work behaviours, conceptualise it as a genuine behavioural addiction, and to apply clinical criteria for addiction to under- stand workaholism as prolonged and extreme behavioural engagement

Resilience–Recovery Factors in Post-traumatic Stress Disorder Among Female and Male Vietnam Veterans: Hardiness, Postwar Social Support, and Additional Stressful Life Events

Structural equation modeling procedures were used to examine relationships among several war zone stressor dimensions, resilience-recovery factors, and post-traumatic stress disorder symptoms in a national sample of 1,632 Vietnam veterans (26% women and 74% men). A 9-factor measurement model was specified on a mixed-gender subsample of the data and then replicated on separate subsamples of female and male veterans. For both genders, the structural models supported strong mediation effects for the intrapersonal resource characteristic of hardiness, postwar structural and functional social support, and additional negative life events in the postwar period. Support for moderator effects or buffering in terms of interactions between war zone stressor level and resiliencerecovery factors was minimal

Advanced information processing system: The Army fault tolerant architecture conceptual study. Volume 2: Army fault tolerant architecture design and analysis

Described here is the Army Fault Tolerant Architecture (AFTA) hardware architecture and components and the operating system. The architectural and operational theory of the AFTA Fault Tolerant Data Bus is discussed. The test and maintenance strategy developed for use in fielded AFTA installations is presented. An approach to be used in reducing the probability of AFTA failure due to common mode faults is described. Analytical models for AFTA performance, reliability, availability, life cycle cost, weight, power, and volume are developed. An approach is presented for using VHSIC Hardware Description Language (VHDL) to describe and design AFTA's developmental hardware. A plan is described for verifying and validating key AFTA concepts during the Dem/Val phase. Analytical models and partial mission requirements are used to generate AFTA configurations for the TF/TA/NOE and Ground Vehicle missions

Restorative servicescapes in health care: examining the influence of hotel-like attributes on patient well-being

This study examines how 527 patients across different health states assessed the influence of hotel-like attributes on their well-being. Using theoretical mechanisms of attention restoration underlying restorative servicescapes, we postulated that hotel-like products and services will enhance patients’ perceived well-being, which, in turn, will favorably affect their behavioral intentions. We also tested an alternative model that included additional direct relationships between hotel-like products and services and behavioral intentions, based on the tenets of cue utilization theory. After conducting a series of nested model comparison procedures, we confirmed that the alternative model provided a theoretically and empirically stronger explanation for the dynamics of hotel-like restorative servicescapes. Although the differences between less healthy and more healthy patients were not statistically significant, the less healthy group demonstrated the same pattern of relationships as in the overall model, indicating that such patients may be more likely to derive greater restorative benefits from hotel-like hospital rooms, which may also make them more likely to pay higher out-of-pocket expenses for such rooms. The study furthers the empirical research agenda on evidence-based design (EBD) and the role of hospitality in health care.Accepted manuscrip

Altered structural and effective connectivity in anorexia and bulimia nervosa in circuits that regulate energy and reward homeostasis.

Anorexia and bulimia nervosa are severe eating disorders that share many behaviors. Structural and functional brain circuits could provide biological links that those disorders have in common. We recruited 77 young adult women, 26 healthy controls, 26 women with anorexia and 25 women with bulimia nervosa. Probabilistic tractography was used to map white matter connectivity strength across taste and food intake regulating brain circuits. An independent multisample greedy equivalence search algorithm tested effective connectivity between those regions during sucrose tasting. Anorexia and bulimia nervosa had greater structural connectivity in pathways between insula, orbitofrontal cortex and ventral striatum, but lower connectivity from orbitofrontal cortex and amygdala to the hypothalamus (P<0.05, corrected for comorbidity, medication and multiple comparisons). Functionally, in controls the hypothalamus drove ventral striatal activity, but in anorexia and bulimia nervosa effective connectivity was directed from anterior cingulate via ventral striatum to the hypothalamus. Across all groups, sweetness perception was predicted by connectivity strength in pathways connecting to the middle orbitofrontal cortex. This study provides evidence that white matter structural as well as effective connectivity within the energy-homeostasis and food reward-regulating circuitry is fundamentally different in anorexia and bulimia nervosa compared with that in controls. In eating disorders, anterior cingulate cognitive-emotional top down control could affect food reward and eating drive, override hypothalamic inputs to the ventral striatum and enable prolonged food restriction

EXPLAINING SATISFACTION IN DOUBLE DEVIATION SCENARIOS: THE EFFECTS OF ANGER AND DISTRIBUTIVE JUSTICE

Research has shown that more than half of attempted recovery efforts only reinforce dissatisfaction, producing a ‘double deviation’ effect. Surprisingly, these double deviation effects have received little attention in service marketing literature. Yet no study has specifically investigated which are the main determinants of the formation of customer satisfaction judgments in double deviation contexts. To fill this gap, we develop and empirically test a model based on the existing service recovery literature. Specifically, we focus on two theoretical frameworks: social justice theory and theories of emotion. We examine the effect of anger with service recovery on satisfaction with service recovery, as well as the role of distributive justice on the elicitation of the specific emotion of anger with service recovery and satisfaction with service recovery. Results support the model and highlight the important role of specific recovery-related emotions in double deviation contexts. Implications for practice and future research are discussed. La investigación previa ha mostrado que más de la mitad de los esfuerzos de recuperación sólo refuerzan la insatisfacción, produciendo un efecto de desviación doble. Sorprendentemente, estos efectos de desviación doble han recibido muy poca atención en la literatura de marketing de servicios. Hasta la fecha, ningún trabajo ha investigado empíricamente cuáles son los principales determinantes en la formación de los juicios de satisfacción en contextos de desviación doble. Para cubrir este hueco, desarrollamos y analizamos empíricamente un modelo basado en la literatura de recuperación de servicios existente. Específicamente, nos basamos en dos esquemas conceptuales: la teoría de la justicia social y las teorías sobre emociones. Examinamos el efecto del enfado con la recuperación del servicio en la satisfacción con la recuperación del servicio, así como el papel de la justicia distributiva como activador de emociones específicas de enfado y como antecedente de la satisfacción con la recuperación del servicio. Los resultados confirman el modelo propuesto y ponen de manifiesto el importante papel de las emociones específicas relacionadas con la recuperación en contextos de desviación doble. Finalmente, se discuten las implicaciones de gestión y las líneas futuras de investigación.enfado con la recuperación del servicio, justicia distributiva, satisfacción con la recuperación del servicio, desviación doble, industria bancaria anger with service recovery, distributive justice, satisfaction with service recovery, double deviation, banking industry
