Don’t Curb Your Enthusiasm. The Role of Work Engagement in Predicting Job Performance / [No reprimas tu entusiasmo. El papel del compromiso laboral en la predicción del desempeño]

Substantial evidence supports the idea that engaged workers reach high performance levels. Nevertheless, most research does not take into account that job performance is multidimensional. The current study aimed to investigate the relationship between work engagement and performance (task performance, contextual performance, counterproductive work behaviors, and adaptive performance) and determine whether work engagement provides incremental validity over the Big Five personality traits in the prediction of performance. A questionaire with the variables of interest was filled in by 365 workers. Regression analyses revealed that work engagement plays a role in all dimensions of job performance. Results also revealed the differential functioning of work engagement dimensions, with vigor as the main predictor of task performance and the second predictor of adaptive performance, even when considering personality. High absorption decreases task performance but increases contextual performance, while dedication mediates between personality (i.e., agreeableness and extraversion) and CWB.(AU)

Existe una evidencia sólida sobre el hecho de que los trabajadores comprometidos alcanzan altos niveles de desempeño. Sin embargo, la mayoría de las investigaciones no tienen en cuenta que el desempeño laboral es multidimensional. El presente estudio tiene como objetivos investigar la relación entre el compromiso laboral y el desempeño (de tarea, contextual, conductas contraproductivas y adaptativo) y determinar si el compromiso laboral aumenta la validez predictiva de los cinco grandes rasgos de personalidad en la predicción del desempeño. Se administró un cuestionario con las variables de interés a 365 trabajadores. Los análisis de regresión muestran que el compromiso laboral juega un papel en la predicción de todas las dimensiones del desempeño laboral. Los resultados también revelaron el funcionamiento diferencial de las dimensiones del compromiso laboral, siendo el vigor el principal predictor del desempeño de tarea y el segundo predictor del desempeño adaptativo, incluso cuando se controlan los rasgos de personalidad. Una gran absorción disminuye el desempeño de tarea, pero aumenta el contextual, mientras que la dedicación actúa como variable mediadora entre la personalidad (amabilidad y extraversión) y las conductas contraproductivas.(AU)

Detection of intimate partner aggression through dark personality and moral disengagement.

Health professionals are often the first to detect abuse. Intimate partner aggression can be approached by studying the personality of the aggressor. From this perspective, dark personality and the use of moral disengagement mechanisms are two key variables. In this study, information was collected from 348 individuals, mostly women, and a questionnaire was applied to determine what their sexual behavior was like with their partner. The Short Dark Tetrad (SD4) test was used to identify dark personality and the Propensity to Moral Disengagement to identify moral disengagement. Data were collected via Google forms and multivariate decision tree analysis (CHAID growth method) was performed. Results show that men score higher on the variables of dark personality variables and use of moral disengagement mechanisms than on the three variables that, along with sex, increase the presence of dark personality and moral disengagement mechanisms: infidelity, pornography consumption, and maintaining homosexual relationships. Infidelity and pornography consumption are characteristics present in all dimensions of dark personality. Moreover, these three variables are defining characteristics of relationships with high sadism scores. Nursing staff are possibly able to detect the presence of these variables in aggressors and thus initiate a process of victim protection. Therefore, this study proposes that nursing staff should be trained to perform this detection.

Oral rehabilitation of a saxophone player with orofacial pain: a case report.

This paper presents a clinical case study investigating the pattern of a saxophonist's embouchure as a possible origin of orofacial pain. The rehabilitation addressed the dental occlusion and a fracture in a metal ceramic bridge. To evaluate the undesirable loads on the upper teeth, two piezoresistive sensors were placed between the central incisors and the mouthpiece during the embouchure. A newly fixed metal ceramic prosthesis was placed from teeth 13 to 25, and two implants were placed in the premolar zone corresponding to teeth 14 and 15. After the oral rehabilitation, the embouchure force measurements showed that higher stability was promoted by the newly fixed metal-ceramic prosthesis. The musician executed a more symmetric loading of the central incisors (teeth 11 and 21). The functional demands of the saxophone player and consequent application of excessive pressure can significantly influence and modify the metal-ceramic position on the anterior zone teeth 21/22. The contribution of engineering (i.e., monitoring the applied forces on the musician's dental structures) was therefore crucial for the correct assessment and design of the treatment plan.

Resumen: Los profesionales de la salud son a menudo los primeros en detectar abusos. La agresión en la pareja íntima se puede abordar a partir del estudio de la personalidad del agresor. Desde esta perspectiva, la personalidad oscura y el uso de mecanismos de desconexión moral son las dos variables principales. Para ello, se recopiló información de 348 personas, casi todas mujeres, y se les aplicó un cuestionario para determinar el comportamiento de la pareja íntima: la prueba Short Dark Tetrad (SD4) para identificar la personalidad oscura y la escala Propensity to Moral Disengagement. Los datos se recopilaron a través de formularios de Google y se aplicó el análisis estadístico multivariado del árbol de decisión. Los resultados muestran cómo los hombres obtienen puntajes más altos en las variables de personalidad oscura y en el uso de mecanismos de desconexión moral. Además, la infidelidad, el consumo de pornografía, el mantenimiento de las relaciones homosexuales, la infidelidad y el consumo de pornografía se asocian con el logro de puntajes más altos en personalidad oscura y desconexión moral. Además, el mantenimiento de las relaciones homosexuales junto con la infidelidad y el consumo de pornografía son características que definen las relaciones con altas puntuaciones de sadismo cotidiano. Se estima que el equipo de enfermería puede detectar la presencia de estas variables en los agresores y así iniciar un proceso de protección a la víctima. Se propone formar al personal de enfermería para llevar a cabo esta detección.

Além disso, a manutenção de relacionamentos homossexuais, juntamente com a infidelidade e o consumo de pornografia, são características que definem relacionamentos com altos escores de sadismo cotidiano. Estima-se que a equipe de enfermagem possa detectar a presença dessas variáveis nos agressores e, assim, iniciar um processo de proteção à vítima. Propõe-se que a equipe de enfermagem possa ser treinada para realizar essa detecção.

Which Personal and Organizational Factors Influence the Organizational Commitment and Job Satisfaction of Shipyard Blue-Collar Workers?

BACKGROUND: The purpose of this research was to analyze which personal and organizational factors are related to organizational commitment and job satisfaction of shipyard workers who work in different auxiliary shipyard military companies in the north of Spain. METHODS: In total, 567 shipyard workers participated in this cross-sectional survey study. The ages were between 19 and 64 (M = 39.36, SD = 10.01), males 82.52%, females 17.48%. We used a survey that included questions about personal and organizational factors such as physical environment, occupational risks, and psychosocial risks, in addition to the job commitment and job satisfaction scales. RESULTS: The results of this study show that job commitment is significantly related to a higher age, lower education, and environmental risk (low vs. high). Furthermore, job satisfaction (high vs. low) and organizational commitment (high vs. low) is related with environmental risk (low vs. high). Job commitment is also higher in workers with a low educational level and older workers. Job satisfaction is lower in workers with a high educational level. CONCLUSIONS: This study shows that different personal and environmental factors influence the shipyard workers' organizational commitment and job satisfaction.

Dark personality and intimate partner relationships in young adults.

People with dark personality traits tend to be unsympathetic, manipulative, and violent, and this can affect their intimate partner relationships. The objective of this research is to analyze how the presence of the dark personality traits affects young people's intimate couple relationships. Sociodemographic variables, sexual practices, and tendencies towards the partner, moral disengagement (PMD), and the dark personality traits were assessed in 308 participants, all of them aged between 18 and 25, of whom 78.3% were women and 21.2% were men. Men obtained higher scores than women both in moral disengagement and dark personality traits, as did people who were unfaithful or who consumed pornographic content, which conditions the quality of couple relationships. Consistent with this, men with higher levels of dark personality traits and higher use of a moral disengagement mechanism also presented a greater tendency towards infidelity, especially repeated infidelity. Infidelity is highly related to the presence of dark personality traits, unrestricted socio-sexuality, and having more sexual partners. These results aid in the design of interventions to prevent sexual harassment and abuse in young people and their intimate partner relationships.

Revenge in Couple Relationships and Their Relation to the Dark Triad.

BACKGROUND: This research examines how, when a romantic partner commits a perceived transgression that leads to couple break up, vengeful reactions are predicted by the type of transgression and the Dark Triad of personality. METHODS: An incidental sample of 2142 participants, half male and half female aged 18 to 70, completed a questionnaire developed by the authors to assess how they had reacted after being the perceived victims of a transgression committed by their partner and a measure of the Dark Triad. RESULTS: Results show half of the people who feel as though they are victims of a partner transgression show revenge reactions. These reactions are more emotional than rational and do not usually anticipate their consequences or success. Moreover, revenge is related primarily to psychopathy and to a lesser extent to Machiavellianism. Psychopathy is the best predictor for revenge thoughts and actions, whereas narcissism does not predict revenge when controlling for other dark traits. CONCLUSIONS: This study contributes to the explanation of revenge reactions in couple relationships in relation to the type of transgression perceived and the Dark Triad. Conflicts that arise out of revenge may have long-lasting consequences for both the perceived aggressor and victim, and our results may be useful for assessing risks, monitoring, and preventing negative consequences for partners or ex-partners.

Intimate Partner Aggression Committed by Prison Inmates with Psychopathic Profile.

Psychopathy and intimate partner aggression (IPA) are two concepts that usually appear concomitantly. Male violence toward women is often considered a psychopathic trait that sometimes involves the woman's homicide by her partner and, at other times, attempted homicide. This phenomenon has been studied by conducting interviews following Hare's model with 92 men incarcerated under a compliance regime in a Spanish prison (Córdoba). The results detected six explanatory factors of IPA as a result of attempted homicide or homicide: criminal past and delinquency, impulsivity, the need to stand out from others, lack of empathy, manipulation of others, and instability in partner relationships. The first two factors predict a occurrence of high scores on Hare's Psychopathy Checklist. The results are discussed, and future lines of research are presented, especially focused on the concept of dehumanization and revenge.

Personality Variables as Predictors of Health Services Consumption.

Expenditure on healthcare and services can be a serious problem for public health. Personality variables should be included as indicators to be considered when studying the consumption of health resources and their planning. This study aims to identify the psychological and psychosocial variables that identify people who can be considered high consumers of health resources versus those who barely consume such resources. The sample was made up of a total of 1124 subjects; one half were men, and one half were women, all of legal age and residents in Spain. A battery of tests was created that included a questionnaire of sociodemographic variables and of healthcare consumption, as well as several psychological variables (Zimbardo Time Paradox Inventory, Multidimensional Locus of Control Scale, Psychological Reactance Scale, Coping Responses Inventory, self-efficacy scale applied to health, and the Symptom Checklist-90-R). The following variables of the model were significant predictors (p ≤ 0.05): a negative past, a fatalistic present, psychological cognitive reactance, behavioral coping, health self-efficacy, and the level of somatization. Data from the statistical analyses show how to create a psychological profile of people who are high consumers of healthcare resources that will allow for the creation of intervention programs in this regard.

The Challenge of Dental Education After COVID-19 Pandemic - Present and Future Innovation Study Design.

The present work suggests research and innovation on the topic of dental education after the COVID-19 pandemic, is highly justified and could lead to a step change in dental practice. The challenge for the future in dentistry education should be revised with the COVID-19 and the possibility for future pandemics, since in most countries dental students stopped attending the dental faculties as there was a general lockdown of the population. The dental teaching has an important curriculum in the clinic where patients attend general dentistry practice. However, with SARS-CoV-2 virus, people may be reluctant having a dental treatment were airborne transmission can occur in some dental procedures. In preclinical dental education, the acquisition of clinical, technical skills, and the transfer of these skills to the clinic are extremely important. Therefore, dental education has to adapt the curriculum to embrace new technology devices, instrumentations systems, haptic systems, simulation based training, 3D printer machines, to permit validation and calibration of the technical skills of dental students.

Beyond the Pale: Dark Traits and Close Relations Influence Attitudes toward COVID-19 and the Rejection of Quarantine Rules.

Dark personality traits are predictors of detrimental behavior (e.g., selfishness or violating norms). This research examined the influence dark personality traits on attitudes toward the COVID-19 pandemic and quarantine rules. We determined whether specific dark traits could predict non-compliance, beyond the global measure of dark personality traits. Additionally, previous research suggests that people are more likely to violate rules for the benefits of close relations, rather than for their own self-interests. We examined how this tendency interacts with dark traits. The 823 participants in the study completed measures of the dark triad, moral disengagement, and attitudes toward COVID-19 rules, and responded to vignettes about themselves or close relations escaping quarantine. Using a bifactor model approach, results showed that a general dark factor predicted non-compliance to COVID-19 rules, but that some moral disengagement mechanisms contributed to non-compliance beyond this factor. Vignette results showed that participants were more willing to break quarantine rules for a close relation than for themselves, except for those high in moral disengagement, who broke rules more-regardless of who was involved. These findings have important implications for intervention programs and policies, since individuals with dark traits tend to "selfishly" trespass norms, but anyone can "go beyond the pale, i.e., go outside the limits of acceptable behavior, for a loved one.

Tooth Position in Wind Instrument Players: Dentofacial Cephalometric Analysis.

BACKGROUND: Specific dentofacial characteristics in wind instrumentalists should be taken in consideration when analyzing physiological and anatomical issues regarding the musician's embouchure, posture, and biomechanics during musical performance. OBJECTIVES: To compare tooth cephalometric characteristics between wind instrument players and string players (overjet, overbite, lower facial height, facial convexity, lower incisor inclination, and interincisal angle). METHODS: In total, 48 wind instrumentalists (67%) and 24 string instrumentalists (33%). These musicians performed lateral tele-radiography and the correspondent linear and angular measurements of the dentofacial cephalometric analysis. Statistical comparison of wind and string instrumentalists was made by using an independent t-test. RESULTS: Small variations on the analyzed parameters were found between the wind and string instrument groups. Based on the cephalometric analysis the variable interincisal angle was statistically significant (p < 0.05), when comparing the wind and string instrument group. CONCLUSIONS: Knowledge of the overjet and overbite value permits a substantial analysis on the tooth position of wind instrument players, where both of these parameters are increased and greater than the norm value. The cephalometry was an added value on the interpretation of possible factors that lead to the position of the central incisors of wind instruments. Till some extent in this group of musicians the applied forces during the embouchure mechanism on the anterior teeth and the existing perioral forces promote an equilibrium on the vector of forces. This study findings demonstrate that when evaluating the two samples, wind and string instruments there are different dentofacial configurations, however the only statistically significant differences that were found are related to the interincisal angle (p < 0.05).

Development of a valid psychological scale for youth police selection among young unemployed and excluded persons: The Nemesis scale.

BACKGROUND: Youth, unemployment and poverty confirm a set of situations that are often inseparable. An example of this is the case of young people from the Andean coca areas. OBJECTIVE: To develop and validate a psychological test that can be used as a predictor of adequate police performance for use in police force recruitment. METHODS: The study comprised a sample of 713 young people, who were selected to join a pre-police training program designed to allow them to subsequently join the Peruvian police force. A new 200-item instrument, called Nemesis, was created. Derogatis' SCL-90 test was administered to determine the validity of the new instrument. The suitability of the items for the future questionnaire was determined through factor analysis, which reduced the questionnaire to 14 items. Logistic regression was used to determine whether the items on the scale could predict possible admittance into the police training academy. RESULTS: A statistical regression analysis showed that the global percentage of correct predictions exceeded chance by almost 15%. Based on this analysis, the scale was determined to be valid. CONCLUSIONS: The proposed objective of verifying the psychometric properties of the Nemesis scale was fulfilled, as the scale has adequate reliability and validity.

Orofacial Trauma on the Anterior Zone of a Trumpet's Player Maxilla: Concept of the Oral Rehabilitation-A Case Report.

BACKGROUND: The occurrence of an orofacial trauma can originate health, social, economic and professional problems. A 13-year boy suffered the avulsion of tooth 11 and 21, lost at the scenario. METHODS: Three intraoral appliances were manufactured: A Hawley appliance with a central expansion screw and two central incisors (1), trumpet edentulous anterior tooth appliance (2) and a customized splint (3) were designed as part of the rehabilitation procedure. Objectively assessing the sound quality of the trumpet player with these new devices in terms of its spectral, temporal, and spectro-temporal audio properties. A linear frequency response microphone was adopted for precision measurement of pitch, loudness, and timbre descriptors. RESULTS: Pitch deviations may result from the different intra-oral appliances due to the alteration of the mouth cavity, respectively, the area occupied and modification/interaction with the anatomy. This investigation supports the findings that the intra-oral appliance which occupies less volume is the best solution in terms of sound quality. CONCLUSIONS: Young wind instrumentalists should have dental impressions of their teeth made, so their dentist has the most reliable anatomy of the natural teeth in case of an orofacial trauma. Likewise, the registration of their sound quality should be done regularly to have standard parameters for comparison.

Burnout and Time Perspective of Blue-Collar Workers at the Shipyard.

Background: The aim of the research was to investigate the association between time perspective in relation to burnout and successful ageing of blue-collar workers with physically highly demanding work and low autonomy. Shipyard blue-collar workers usually do predominantly manual labor versus white-collar workers, whose jobs do not usually involve physical work. Methods: 497 participants workers in a shipyard in the north of Spain. Ages were between 20 and 69 (M = 46.62, SD = 10.79). We used the Zimbardo Time Perspective Instrument (ZTPI), Spanish version, and the Maslach Burnout Inventory-General Survey (MBI-GS). Results: Emotional exhaustion factor obtained a coefficient of 0.97; cynicism factor of 0.83; and professional efficacy factor of p = 0.86. The mean of the three reliability coefficients was 0.887. With respect to the five factors of the ZTPI questionnaire: the negative past factor obtained a coefficient of p = 0.91; that of positive past p = 0.81; the present hedonistic of 0.878; the future of p = 0.83; and the fatalistic present of p = 0.90. The mean of the five coefficients, was p = 0.86. Conclusions: Within shipyard workers, burnout is associated with a negative past and negative future time perspective. This makes shipyard workers at a higher risk of developing burnout and this can have serious consequences for the sustainable employability of these blue-collar workers.

Craniofacial morphology of wind and string instrument players: a cephalometric study.

BACKGROUND: Playing an instrument may promote a parafunctional behavior within the cranio-cervical-mandibular-complex with unknown repercussions. The aim of this study was to find any association between the dental inter-arch relationship and the practice of a wind or string instrument. METHODS: A sample of 77 musicians, divided in two groups of wind (n = 50) and string instrumentalists (n = 27), had a lateral cephalogram taken to compare six cephalometric parameters following the Rickett's analysis (maxilla position, mandible position, facial type, skeletal class, upper incisor and lower incisor inclination). The Fisher test was performed to compare, with a 95% statistical confidence, if both groups have similar frequency distributions for each cephalometric parameter. RESULTS: No statistical differences were found for the maxilla position, mandible position, facial type, skeletal class and upper incisor inclination. Statistical differences were found for the lower incisor inclination (p = 0.011). CONCLUSIONS: Playing a wind instrument showed to have little orthopaedic influence at the craniofacial morphology, on contrary it may influence the lower incisor inclination with its osseous base.

The Dark Triad and the Detection of Parental Judicial Manipulators. Development of a Judicial Manipulation Scale.

This research examines the relationship between dark triad and the use that some parents make of their children in order to attack the other parent after a couple break-up. We examined whether parents who are willing to lie about issues concerning the other parent and their children during a couple break-up process show higher levels of dark triad traits. Across two different samples of divorced participants (N = 1085 and N = 249), we measured dark triad traits and willingness to engage in judicial manipulation. The objective of this study was to build a judicial manipulation scale to measure willingness to lie and use children to harm the other parent that could be used in professional practice. Results show significant correlations for judicial manipulation and dark triad traits and confirm the psychometric properties of reliability and validity of a proposed scale. We found that dark triad traits are adequate indicators of judicial manipulation. We discuss the importance of the scale to help the judicial system to determine which parent is the most appropriate to be designated as the legal custodial parent.

Adhesive dentistry sensory stimulus technique as a neuromechanism for the treatment of orofacial pain associated to temporomandibular disorders: Case study.

PURPOSE: The authors intend, by presenting a case study, emphasize the neuromodulation process of orofacial pain induced by the stimulation of the sensory and motor stimulation of the trigeminal nerve, which can play an important role on pain modulation. MATERIALS AND METHODS: A 25 year-old woman presenting orofacial pain was referred to the stomatology service at the Centro Hospitalar do Porto. After collecting the patient's anamnesis, the thermographic camera FLIR i7 was used to record the thermal status of the orofacial structures, before the adhesive dentistry sensory stimulus protocol, after 45 minutes, and after one week. RESULTS: This study suggests the relation of adhesive dentistry sensory stimulus technique in the neuromodulation of orofacial pain and its association with the temporomandibular disorders . As the tongue senses the stimulus of the resin composite placed on the palatal surface of the 1st premolar, 2nd premolar and 1st molar of the maxilla, this can promote and induce an effect regarding a peripheral nerve neuromodulation resulting in a blockage of the nociceptive trigeminal pathway from temporomandibular disorders. CONCLUSION: Orofacial pain is a common complaint among the patients that come to a dentistry appointment, which may have different diagnosis and treatments. A positive effect on the patient's symptomatology was confirmed clinically on subsequent dental appointments and monitored by infrared thermography.

Infrared thermography of the crânio-cervico-mandibular complex in wind and string instrumentalists.

PURPOSE: Musculoskeletal disorders can be common in wind and string instrumentalists. The musical gesture technique associated to musical performance can promote an asymmetrical isometric contraction with the hyperactivity of specific muscular groups and the overload of articular surfaces which can cause discomfort or pain. The aim of this investigation was to assess specific anatomical regions of interest within the cranio-cervico-mandibular complex in order to determine and evaluate the presence of muscular hyperactivity associated to musical performance. METHODS: An infrared imaging camera, FLIR®, was used to record the regions of interest in wind (n = 48) and string instrumentalists (n = 29). Bilateral temperature differences were considered as thermal asymmetries with a conventional threshold of 0.3 ºC to distinguish pathological from healthy states. The regions of interest (ROI) were the anterior triangle of the neck, the sternocleidomastoid and trapezius muscles regarding the postural and stabilizing muscles of the head and neck. On the orofacial region, the anatomical sites were the anterior temporal muscle, the masseter muscle and the temporomandibular joint. A Pearson chi-square test was performed to compare the assessed areas. RESULTS: Between 30-37% of all participants showed ROI in an asymmetric pattern. The most affected sites were the temporal muscle and the TMJ for both groups. The anterior triangle of the neck showed statistical differences (p = 0.044) between string and wind instrumentalists, while the temporal (p = 0.034) and trapezius muscle (p = 0.028) when comparing large and small mouthpieces of brass instruments. Although female participants showed a higher prevalence of asymmetrical patterns regarding the ROI, no statistical differences were found between genders. CONCLUSIONS: Infrared thermography exhibited significant differences between wind and string instruments within the CCMC. Regarding the issue of occupational health in performing arts, it is an advantage being able to quantify asymmetrical patterns sites of the CCMC to understand the underlying physiological responses to repetitive movements, overloading and muscular hyperactivity that occur during musical performance.

Types of love as a function of satisfaction and age.

Research studies on love have focused on the study of typologies, among which Sternberg's triangular theory of love and the typology of Hendrick and Hendrick deriving from that of Sternberg have been the most common and empirically verified. Love types have been linked to all types of sociodemographic and psychological variables. However, these studies possess shortcomings: When the data are analyzed according to age, only a few ranges are studied; with respect to other variables such as satisfaction, typically only two levels are studied, and no continuous study is conducted. This study attempts to overcome these limitations. It analyzes types of love according to the two systems noted earlier and based on two variables: age and satisfaction. For satisfaction, the Satisfaction With Life Scale (SWLS) by Diener et al. was used, and 439 subjects aged 15 to 89 years participated in the study. The results show that both of the variables-age and satisfaction-explain that love types occur in varying degrees; however, satisfaction is more predictive than is age. Possibilities for future research are discussed.
