Salicylic Acid and Calcium Chloride Seed Priming: A Prominent Frontier in Inducing Mineral Nutrition Balance and Antioxidant System Capacity to Enhance the Tolerance of Barley Plants to Salinity.

The current investigation aims to underline the impact of salicylic acid or calcium chloride seed pre-treatments on mineral status and oxidative stress markers, namely levels of electrolyte leakage (EL) and lipid peroxidation levels, measured as thiobarbituric reactive substances (TBARS), and the activity of some antioxidant enzymes in roots and leaves of plants in two barley species grown under various salt treatments. Overall, our results revealed that salinity inhibits essential nutrient absorption such as iron, calcium, magnesium and potassium and stimulates the absorption of sodium. Also, this environmental constraint induced oxidative stress in plants in comparison with the control conditions. This state of oxidative stress is reflected by an increase in TBARS content as well as the stimulation of EL values. In addition, salinity induced disturbances in the activity of antioxidant enzymes, which were mainly dependent on the applied salt concentration and the species. In addition, Hordeum marinum maintained high antioxidant enzyme activity and low levels of oxidative stress parameters, which reinforces its salt-tolerant character. Importantly, salicylic acid or calcium chloride seed priming alleviated the mineral imbalance and the oxidative damage induced by salinity. Moreover, seed priming improves iron, calcium magnesium and potassium content and limitsthe accumulation of sodium. Also, both treatments not only decrease TBARS levels and limit EL, but they also stimulate the antioxidant enzyme activities in the leaves and roots of the stressed plants as compared with stressed plants grown from non-primed seeds. Interestingly, the beneficial effects of the mentioned treatments were more notable on Hordeum vulgare species.

Reconstruction of lateral coherence and 2D emittance in plasma betatron X-ray sources.

X-ray sources have a strong social impact, being implemented for biomedical research, material and environmental sciences. Nowadays, compact and accessible sources are made using lasers. We report evidence of nontrivial spectral-angular correlations in a laser-driven betatron X-ray source. Furthermore, by angularly-resolved spectral measurements, we detect the signature of spatial phase modulations by the electron trajectories. This allows the lateral coherence function to be retrieved, leading to the evaluation of the coherence area of the source, determining its brightness. Finally, the proposed methodology allows the unprecedented reconstruction of the size of the X-ray source and the electron beam emittance in the two main emission planes in a single shot. This information will be of fundamental interest for user applications of new radiation sources.

Classification accuracy and resistance to coaching of the Spanish version of the Inventory of Problems-29 and the Inventory of Problems-Memory: A simulation study with mTBI patients.

Objective: The present study aims to evaluate the classification accuracy and resistance to coaching of the Inventory of Problems-29 (IOP-29) and the IOP-Memory (IOP-M) with a Spanish sample of patients diagnosed with mild traumatic brain injury (mTBI) and healthy participants instructed to feign. Method: Using a simulation design, 37 outpatients with mTBI (clinical control group) and 213 non-clinical instructed feigners under several coaching conditions completed the Spanish versions of the IOP-29, IOP-M, Structured Inventory of Malingered Symptomatology, and Rivermead Post Concussion Symptoms Questionnaire. Results: The IOP-29 discriminated well between clinical patients and instructed feigners, with an excellent classification accuracy for the recommended cutoff score (FDS ≥ .50; sensitivity = 87.10% for coached group and 89.09% for uncoached; specificity = 95.12%). The IOP-M also showed an excellent classification accuracy (cutoff ≤ 29; sensitivity = 87.27% for coached group and 93.55% for uncoached; specificity = 97.56%). Both instruments proved to be resistant to symptom information coaching and performance warnings. Conclusions: The results confirm that both of the IOP measures offer a similarly valid but different perspective compared to SIMS when assessing the credibility of symptoms of mTBI. The encouraging findings indicate that both tests are a valuable addition to the symptom validity practices of forensic professionals. Additional research in multiple contexts and with diverse conditions is warranted.

Workplace violence in hospital emergency departments and consequences for health care professionals and support staff: a cluster analysis. / Violencia laboral de usuarios y sus consecuencias sobre profesionales sanitarios y no sanitarios de los servicios de urgencias hospitalarios: análisis de clúster.

OBJECTIVES: Workplace violence of any type is influenced by multiple factors and leads to physiological, psychological, social, and organizational change. Emergency and other urgent care settings have assault rates up to 5-fold higher than other health care settings. This study aimed to analyze the consequences of physical and nonphysical violence on health care and support personnel in hospital emergency departments. MATERIAL AND METHODS: Cross-sectional descriptive analysis of responses to a 121-item survey of 584 health care and support workers in 12 Spanish hospital emergency departments. We analyzed the magnitude of the problem with a two-step self-clustering method and then assessed the associations between variables and workplace violence. RESULTS: Two groups were identified. The first consisted of 298 cases with high mean (SD) scores for nonphysical assaults (51.5 [7.9]) and low scores for physical violence (4.8 [2.9]). The second group consisted of 285 cases with intermediate scores for nonphysical assaults (27.1 [8.4]) and low scores for physical violence (3.4 [1.3]). CONCLUSION: Emergency departments have incidents of nonphysical workplace violence more often than physical violence. Emergency personnel with high exposure to workplace violence, particularly nonphysical assaults, experience physiological, psychosocial, and organizational changes.

Sex Moderates the Relationship Between Social Support and Cardiovascular Prevention Behaviors in Middle-aged and Older Adults.

BACKGROUND: Most risk factors for cardiovascular disease (CVD) are modifiable, suggesting that the burden of CVD could be substantially reduced through cardiovascular screening and healthier lifestyle. People who have social support are more likely to adhere to cardiovascular prevention recommendations, but it is not clear whether the benefit of social support is equal for men and women. PURPOSE: We investigated whether sex moderates the relationship between social support and adherence to cardiovascular prevention recommendations in a nationally representative sample. METHODS: Participants were 17,287 adults (n = 10,264 middle-aged adults 40-64 years old and n = 7,023 older adults ≥ 65 years old) who participated in the National Health Survey of Spain in 2017. Social support was measured with the Functional Social Support Questionnaire of Duke-UNC. Adherence to cardiovascular screening recommendations was assessed based on self-reported testing of cholesterol, blood pressure, and blood sugar by a health professional in the past 12 months. Adherence to recommended health-related behaviors was assessed based on the guidelines of the European Society of Cardiology regarding diet, alcohol consumption, smoking, and physical activity. RESULTS: Multiple regression models adjusted for socio-demographic and cardiovascular history and risk variables showed that social support was more strongly associated with adherence to cardiovascular prevention recommendations in men than in women. In particular, low social support levels were especially detrimental for both middle-aged men (screening: B = 0.13, 95% CI [0.06-0.20], p < .001; behaviors: B = 0.33 [0.26-0.41], p < .001) and older men (screening: B = 0.10 [0.04-0.17], p = .001; behaviors: B = 0.16 [0.08-0.25], p < .001), whereas older women had comparatively high adherence, which was unrelated to social support (screening: B = 0.02 [-0.03 to 0.08], p = .433; behaviors: B = 0.03 [-0.03 to 0.10], p = .342). CONCLUSIONS: Social support is more strongly associated with cardiovascular prevention in men than in women, such that men who lack social support have the lowest adherence to cardiovascular screening and lifestyle recommendations.

To help prevent cardiovascular disease, experts recommend screening for cardiovascular risk factors and leading a healthy lifestyle. Previous research has found that people who have social support are more likely to adhere to such cardiovascular prevention recommendations. In this study, using data form a nationally representative survey, we investigated whether the relationship between social support and adherence to cardiovascular prevention recommendations is different for men and women. Participants were 17,287 adults from the National Health Survey of Spain, who reported their cardiovascular screening history (i.e., whether they had their cholesterol, blood pressure, and blood sugar levels tested by a health professional in the past 12 months) and their lifestyle habits regarding diet, alcohol consumption, smoking, and physical activity. Social support was more strongly associated with cardiovascular prevention in men than in women, such that men who lacked social support had the lowest adherence to cardiovascular screening and lifestyle recommendations.

Fishing the Targets of Bioactive Compounds from Psidium guajava L. Leaves in the Context of Diabetes.

Psidium guajava L. (guava) leaves have demonstrated their in vitro and in vivo effect against diabetes mellitus (DM). However, there is a lack of literature concerning the effect of the individual phenolic compounds present in the leaves in DM disease. The aim of the present work was to identify the individual compounds in Spanish guava leaves and their potential contribution to the observed anti-diabetic effect. Seventy-three phenolic compounds were identified from an 80% ethanol extract of guava leaves by high performance liquid chromatography coupled to electrospray ionization and quadrupole time-of-flight mass spectrometry. The potential anti-diabetic activity of each compound was evaluated with the DIA-DB web server that uses a docking and molecular shape similarity approach. The DIA-DB web server revealed that aldose reductase was the target protein with heterogeneous affinity for compounds naringenin, avicularin, guaijaverin, quercetin, ellagic acid, morin, catechin and guavinoside C. Naringenin exhibited the highest number of interactions with target proteins dipeptidyl peptidase-4, hydroxysteroid 11-beta dehydrogenase 1, aldose reductase and peroxisome proliferator-activated receptor. Compounds catechin, quercetin and naringenin displayed similarities with the known antidiabetic drug tolrestat. In conclusion, the computational workflow showed that guava leaves contain several compounds acting in the DM mechanism by interacting with specific DM protein targets.

Violencia de género: perspectiva de condenados y de psicólogos/as de instituciones penitenciarias. Análisis cualitativo con grupos focales / Intimate Partner Violence: perspective of convicts and psychologists of penitentiary institutions. A Qualitative analysis with focus groups

La violencia de género es un proceso complejo en el cual intervienen variables individuales, relacionales y contextuales. El presente estudio tiene como objetivo explorar las estrategias de afrontamiento y dinámicas relacionales en situaciones conflictivas en condenados por violencia de género con sus parejas. Se realizaron grupos focales con condenados por violencia de género (12 participantes) y con profesionales de la psicología (4 participantes). Los datos se exploraron mediante análisis temático siguiendo el Modelo Ecológico Anidado. El grupo de condenados muestra roles de autoridad y superioridad sobre la mujer, sensación de vulnerabilidad y rechazo ante el marco jurídico existente, miedo a sufrir arrestos por querer continuar con la relación, la necesidad de control de la pareja impulsada por lo celos, la justificación o negación de responsabilidad en las situaciones violentas o instrumentalización de los hijos/as en común. Los profesionales señalan aspectos culturales que facilitan esquemas y roles violentos en la dinámica de pareja, problemas de comunicación, negación o baja conciencia del delito, entre otros temas. Los resultados son de especial interés tanto para los profesionales que deseen conocer o profundizar en la temática como para quienes trabajen en la intervención y/o prevención en violencia de género.(AU)

Intimate Partner Violence is a complex process in which indi-vidual, relational and contextual variables intervene. The aim of this study was to explore coping strategies and relational dynamics in conflict situa-tions involving people convicted of intimate partner violence with their partners. Focus groups were conducted with convicted intimate partner violence offenders (12 participants) and with psychology professionals (4 participants). The data were explored through thematic analysis following the Nested Ecological Model. The group of convicted perpetrators showed roles of authority and superiority over the woman, a feeling of vulnerability and rejection of the existing legal framework, fear of being arrested for wanting to continue the relationship, the need to control the partner driven by jealousy, justification or denial of responsibility in violent situations or instrumentalization of the children in common. The professionals point out cultural aspects that facilitate violent patterns and roles in the couple's dynamics, communication problems, denial or low awareness of the crime, among other issues. The results are of special interest both for profession-als who wish to learn or deepen their knowledge on the subject, as well as for those who work in intervention and/or prevention of intimate partner violence.(AU)

(Un)Broken: Lateral violence among hospital nurses, user violence, burnout, and general health: A structural equation modeling analysis.

Introduction: Workplace violence is a social problem yet to be solved. Although it is present in virtually all work environments, its prevalence in healthcare settings stands out, being perceived as something inherent to the job. Most studies in this context have focused on user violence against professionals. However, it has been observed that violence among colleagues in these types of jobs is a risk factor for the health of workers and has rarely been studied as a whole. Among the main consequences of exposure to violence reported in the literature, burnout syndrome, depression, anxiety, or somatic problems have been among the most studied. On the one hand, some authors claim that being exposed to workplace violence can increase the associated physical and psychological pathology and lead to a picture congruent with burnout. On the other hand, it has been hypothesized that violence is associated with burnout, which can trigger physical and psychological symptoms. Taking into account this background, the aim of this study is to explore workplace violence in health personnel, symptomatology, and burnout syndrome through mediation models that allow us to know the interrelationships between the variables. Methods: A cross-sectional design with a double descriptive-associative strategy was used. The sample was composed of 950 nursing professionals from public hospitals. The scales of physical and non-physical violence from users to professionals HABS-U, personal, social, and occupational violence among co-workers using the Health Aggressive Behavior Scale - Co-workers and Superiors (HABS-CS) scale, the burnout scale Maslach Burnout Inventory - General Survey (MBI-GS) which evaluates professional exhaustion, efficacy and cynicism, and the factors referring to depression, anxiety, somatization, and dysfunction of the GHQ-28 scale were applied. In order to calculate the models, workplace violence was used as a predictor of symptomatology, using the burnout variables as mediators. Regression coefficients with and without mediation model, direct and standardized estimates were obtained. For statistical power, Bootstrap analysis was used to calculate direct mediation effects. Results: After controlling the mediation effects of burnout and cynicism, physical and non-physical user violence toward healthcare personnel were significant predictors of the GHQ-28 scores. These same results were obtained when assessing the relationship between social, occupational, and personal violence among co-workers and GHQ-28 scores. Conclusion: Our results contribute to increase the evidence about the effects of violence on the health of professionals and to advance in the characterization of the possible consequent psychological damage. Regardless of the type of violence experienced, exposure to violence can lead to anxious, depressive or somatization symptoms, among others. Violence is also a predictor of burnout syndrome, which in turn accentuates the rest of the consequences studied. Despite the limitations of the proposed model, these results serve to highlight the complexity of the situation experienced by healthcare professionals. Moreover, it serves as a basis for proposing intervention/prevention programs to raise awareness and protect professionals from these risks. To this end, self-care tools should be proposed with which professionals take care of their own health through the management of violent situations and/or the improvement of occupational health.

Relationship between Job Satisfaction and Workload of Nurses in Adult Inpatient Units.

Among Nursing and Psychology professionals, the job satisfaction of those in Adult Inpatient Units is analyzed, with a new scale to measure nursing workloads validated. Objective: The objective of this study was to relate nursing workloads to professional job satisfaction. Methods: This is an observational, analytical, descriptive, concurrent and quantitative study, which used the Overall Job Satisfaction scale and subscales therein, to identify global satisfaction-intrinsic or related to motivational factors and extrinsic or associated with hygienic factors-in nursing professionals (n = 104) from eight Inpatient Units of Internal Medicine and Surgery, in four hospital centers, to describe job satisfaction in the professionals studied and to find statistically significant associations between job satisfaction and workload (measured with the scale MIDENF®) in the inpatient units where they work. Results: There were higher levels of satisfaction in the variables "relationship with immediate boss" and "relationship with fellow workers", and lower levels in "relationship with senior management" and "organizational system of the unit". In the inferential analysis, the scores were 75.63 for overall satisfaction, 35.28 for intrinsic satisfaction, and 40.36 for extrinsic satisfaction. Conclusions: There is a close relationship between workload and job satisfaction, showing more dissatisfaction regarding organizational aspects and professional recognition.

Sources of Conflict and Prevention Proposals in User Violence Toward Primary Care Staff: A Qualitative Study of the Perception of Professionals.

Background: Some studies indicate that at least one in four cases of workplace violence occurs in the health sector, with a higher incidence in Emergency Departments, Mental Health Services or Primary Care. Unlike other professional groups, healthcare workers perceive this type of behavior mainly from users or patients. This is the reason why both the detection of conflict between users and professionals and the ways to face and reduce these conflicts has been and is one of the main fields of study in this population. The aim of this study was to delve into the sources of conflict between users and professionals in Primary Care from the perspective of the professionals themselves. In addition, the aim was to explore the proposals for intervention/prevention of this conflict that the professionals perceived as necessary to improve the work environment. Methods: This study uses qualitative methodology conducting 8 focus groups with professionals related to Primary Health Care. The final sample was composed of 44 workers who were part of the regional management, labor unions, area coordinators, center coordinators and representatives of the professional groups of these centers (medicine, nursing and administration). Thematic analysis was used to extract topics and subtopics. Results: The results are divided into areas of conflict and intervention proposals. The professionals detect a lack of training or education in themselves, absence of functional multidisciplinary teams or competencies to improve the patient-professional relationship, among others. To address these shortcomings, they propose the creation of protocols for action in the face of aggression, the formation of spaces and channels of communication both among the center's own workers and between them and other organizations (e.g., hospitals), fostering a positive relationship with the user community and ongoing training in various topics such as self-safety, management of emotions, empathy or interpersonal communication. Conclusions: This study allows to highlight specific areas of user-professional conflict in Primary Care. Furthermore, the inclusion of intervention proposals by the professionals allows to propose starting points for the development of complete plans.

Self-report Measures for Symptom Validity Assessment in Whiplash-associated Disorders

Background/Objective: Whiplash-Associated Disorders (WAD) are one of the most complex conditions to evaluate because several of its symptoms are not observable with current diagnostic methods and cannot be quantified or evaluated correctly. No method is currently available to assess the risk of malingering in the aforementioned condition efficiently. Our aim is to study the capacity of several biopsychosocial psychometric self-report instruments, such as the Brief Pain Inventory (BPI), the Cervical Disability Index (NDI), the SF-36 Health Questionnaire, the Beck Anxiety and Depression Inventories (BDI-II and BAI), or the Brief Illness Perception Questionnaire (BIPQ), to discriminate between patients diagnosed with WAD following a vehicle accident and non-clinical participants with malingering instructions. Method: A simulation design was used with 630 participants: 200 non-clinical controls with honest responding condition, 201 instructed malingerers, and 229 WAD clinical outpatients. Results: Our results showed an AUC range of .60 to .90, with the highest value being that of the BPI (.90), followed by the NDI (.88), and the lowest value that of the BIPQ (.60), followed by the BAI (.71). Conclusions: Overall, the BPI, the NDI, and SF-36 can correctly discriminate between groups with a good specificity (> 90%), while the BAI, BDI, and BIPQ showed a lower capacity, with a high rate of false positives in the case of the BDI and of false negatives in the other two. Practical and research implications are discussed. (AU)

Antecedentes/Objetivo: El Síndrome del Latigazo Cervical (WAD) es una de las condiciones más complejas de evaluar debido a que varios de los síntomas que presenta no son objetivables con los métodos diagnósticos actuales y no puede cuantificarse ni evaluarse correctamente. En la actualidad no se dispone de ningún método eficiente para valorar el riesgo de simulación en la citada condición. Nuestro objetivo es estudiar la capacidad de varios instrumentos psicométricos biopsicosociales de autoinforme, como el Inventario Breve de Dolor (BPI), el Índice de Discapacidad Cervical (NDI), el Cuestionario de Salud SF-36, los Inventarios de Ansiedad y Depresión de Beck (BDI-II y BAI) o el Cuestionario Breve de Percepción de la Enfermedad (BIPQ) para discriminar entre pacientes diagnosticados con WAD tras un accidente de circulación y participantes no-clínicos con instrucciones de simulación. Método: Se utilizó un diseño de simulación con 630 participantes: 200 controles no clínicos con condición de respuesta honesta, 201 simuladores instruidos y 229 pacientes clínicos con WAD. Resultados: Nuestros resultados mostraron un rango de AUC de .60 a .90, siendo el valor más alto el del BPI (.90), seguido del NDI (.88), y el valor más bajo el del BIPQ (.60), seguido del BAI (.71). Conclusiones: En general, el BPI, el NDI y el SF-36 pueden discriminar correctamente entre grupos con una buena especificidad (> 90%), mientras que el BAI, el BDI y el BIPQ mostraron una menor capacidad, con una alta tasa de falsos positivos en el caso del BDI y falsos negativos en los otros dos. Se discuten además las implicaciones prácticas y de investigación. (AU)

Profiles of lateral violence in nursing personnel of the Spanish public health system.

BACKGROUND: Workplace violence in healthcare settings has long been studied in scientific literature, particularly in the nursing profession. Research has explored mostly user violence probably for its high prevalence and impact on health and job satisfaction. Yet this focus may overshadow another dangerous type of workplace violence: coworker violence. Exerted by co-workers with similar status, lateral violence differs from that yielded by a co-worker with a higher rank, known as vertical. This study aims to deepen the knowledge about lateral violence perceived by nurses and its interaction with other variables commonly associated with workplace violence in healthcare: burnout, job satisfaction, and self-perceived health. METHOD: A random block sampling was performed, prompting a total sample of 925 nursing professionals from 13 public hospitals located in the southeast of Spain. The sample distribution (mean and standard deviation) and the response percentages according to the study variables of the ad-hoc questionnaire were analyzed and classified with cluster analysis. RESULTS: Through the cluster analysis, two subgroups were obtained: Cluster 1, composed of 779 participants, with low scores in the variables used for the classification, high levels of both extrinsic and intrinsic satisfaction, low levels of emotional exhaustion and cynicism, and low rates of somatization, anxiety, social dysfunction and depression; and Cluster 2, composed of 115 participants and characterized by moderate-high scores in the variables used for the classification, moderate extrinsic satisfaction, and low intrinsic satisfaction, high emotional exhaustion and cynicism and lower somatization, anxiety, social dysfunction, and depression scores. Excluded cases amounted to 31. CONCLUSION: Nursing professionals who experience lateral violence reveal a lower intrinsic satisfaction, feeling less self-accomplished in their job, and less positive work experience. Emotional exhaustion rises as a concerning progressive and long-term outcome of experiencing this type of violence.

Angular-Resolved Thomson Parabola Spectrometer for Laser-Driven Ion Accelerators.

This article reports the development, construction, and experimental test of an angle-resolved Thomson parabola (TP) spectrometer for laser-accelerated multi-MeV ion beams in order to distinguish between ionic species with different charge-to-mass ratio. High repetition rate (HHR) compatibility is guaranteed by the use of a microchannel plate (MCP) as active particle detector. The angular resolving power, which is achieved due to an array of entrance pinholes, can be simply adjusted by modifying the geometry of the experiment and/or the pinhole array itself. The analysis procedure allows for different ion traces to cross on the detector plane, which greatly enhances the flexibility and capabilities of the detector. A full characterization of the TP magnetic field is implemented into a relativistic code developed for the trajectory calculation of each pinhole beamlet. We describe the first test of the spectrometer at the 1PW VEGA 3 laser facility at CLPU, Salamanca (Spain), where up to 15MeV protons and carbon ions from a 3µm laser-irradiated Al foil are detected.

Mental Health and Healthy Habits in University Students: A Comparative Associative Study.

There is evidence of increased psychopathology in university students and its relationship with unhealthy lifestyle habits. The objective of this work is to examine the prevalence and differences in psychopathological symptoms and lifestyle in a sample of university students according to educational levels and area of knowledge. A comparative associative study was conducted with 1405 university students. The results indicated significant differences in psychopathology and habits in the different groups. The prevalence of psychopathology found was high, especially depressive and anxious pathologies. This incidence tends to be higher in undergraduates and/or Arts and Humanities, coinciding with those who tend to have poorer lifestyle habits. The promising contributions from this study facilitate the early detection of university students with a risk profile for the appearance or exacerbation of psychopathology, as well as the design of psychological intervention programs aimed at the psychological well-being of this population.

Characterization of Structural Changes of Casein Micelles at Different PH Using Microscopy and Spectroscopy Techniques.

This study aimed to evaluate the influence of pH changes on morphometric parameters of casein micelles and a general overview of their conformational structure through microscopy techniques, Raman spectroscopy and multivariate analysis. It was found that casein micelles morphology and protein secondary structure depend strongly upon pH. The changes of arithmetic average roughness (Ra), size, and shape of casein micelles at different pH are properly characterized by atomic force and cryo-transmission electron microscopy. Morphometric changes of casein micelles were correlated correctly with folding and unfolding of casein molecules as evaluated by Raman spectroscopy when the pH was varied. The novelty of this contribution consists in demonstrating that there is a close structure-functionality relationship between the morphometric parameters of proteins and their secondary structure. Knowledge about casein micelles can help improve their use of its diverse applications.

Assessment of Non-physical User Violence and Burnout in Primary Health Care Professionals. The Modulating Role of Job Satisfaction.

INTRODUCTION: Growing concern about workplace violence shows the need for an evaluation in specific contexts in order to identify the particularities of each professional group. The health sector consists of a group of professionals with high exposure to violence, specially from users. There are differences depending on the professional category or unit in which the professional works. In this regard, Primary Health Care (PHC) is characterized by a personalized and continuous patient treatment over time, which is not exempt from cases of violence. Among the commonly studied consequences of these situations are decreases in job satisfaction and burnout. OBJECTIVE: The main objective of this study is to analyze the modulating role of job satisfaction in the relationship between non-physical user violence and the onset of burnout. METHODS: Cross-sectional comparative descriptive design. The sample consisted of 574 professionals from 39 PHC centers of the Murcian Health Service. Data were collected using two-stage cluster sampling. For data analysis, descriptive analysis, correlations and stepwise hierarchical regression were used to analyze the interaction between the variables. RESULTS: Regression analysis draws a model where non-physical violence and low intrinsic and extrinsic job satisfaction act as modulators of non-physical violence, cynicism and emotional exhaustion. CONCLUSIONS: This study provides evidence of the psychological consequences of the perception of user violence in the PHC staff. Furthermore, it is evident that the emergence of burnout syndrome in these professionals is related to exposure to verbal or non-physical violence together with low job satisfaction. In this sense, a circular and bidirectional relationship between the variables studied is proposed as a possible explanatory model.

A Comparative Study of Post-Quantum Cryptosystems for Internet-of-Things Applications.

The existence of quantum computers and Shor's algorithm poses an imminent threat to classical public-key cryptosystems. These cryptosystems are currently used for the exchange of keys between servers and clients over the Internet. The Internet of Things (IoT) is the next step in the evolution of the Internet, and it involves the connection of millions of low-powered and resource-constrained devices to the network. Because quantum computers are becoming more capable, the creation of a new cryptographic standard that cannot be compromised by them is indispensable. There are several current proposals of quantum-resistant or post-quantum algorithms that are being considered for future standards. Given that the IoT is increasing in popularity, and given its resource-constrained nature, it is worth adapting those new standards to IoT devices. In this work, we study some post-quantum cryptosystems that could be suitable for IoT devices, adapting them to work with current cryptography and communication software, and conduct a performance measurement on them, obtaining guidelines for selecting the best for different applications in resource-constrained hardware. Our results show that many of these algorithms can be efficiently executed in current IoT hardware, providing adequate protection from the attacks that quantum computers will eventually be capable of.

Association Between Attitudes Toward Violence and Violent Behavior in the School Context: A Systematic Review and Correlational Meta-Analysis / Asociación entre actitudes hacia la violencia y conducta violenta en el contexto escolar: Revisión sistemática y meta análisis correlacional

ResumenAntecedentes/Objetivo: Las propuestas teóricas y trabajos empíricos apuntan una con-currencia entre las actitudes y la conducta violenta en el contexto escolar. Los estudios suelen abordan esta cuestión superficialmente o dentro de programas de intervención donde se trabajan múltiples variables, existiendo diferencias en la magnitud de esta re-lación. El objetivo del estudio es describir los resultados de una revisión sistemática y realizar un metaanálisis que explore estas asociaciones. Método: Se realizó una revisión sistemática en las principales bases de datos. Se calcularon los tamaños del efecto y fueron sintetizados mediante un metaanálisis de efecto aleatorio para la relación entre actitudes hacia la violencia y violencia escolar. Se realizó una meta-regresión para el análisis moderador del sexo y edad. Resultados: La estrategia de búsqueda produjo 12.293 artículos. El proceso de revisión estructurado arrojó un resultado final de 23 estudios. Nuestros resultados estiman una relación positiva y significativa (r = 0,368 p < 0,001; 95% CI = [0,323, 0,412]) entre actitudes y violencia escolar en menores. Con-clusiones: Este estudio permite cuantificar con un adecuado grado de especificidad la relación actitud/conducta en el contexto escolar. Estos resultados facilitarían a futuros investigadores plantear programas que aborden esta especificidad para mejorar el clima escolar.

AbstractBackground/Objective: Both theoretical proposals and empirical work point to a common concurrence between attitudes toward school violence and violent behavior. Studies often address this issue superficially or within intervention programs. Our objective is to describe the results of a systematic review and to conduct a meta-analysis exploring these associations. Method:A systematic review was conducted in the main databases. Effect sizes were calculated and synthesized using random-effects meta-analysis to estimate the relationship between attitudes toward violence and school violence. A meta-regression was performed for the moderator analysis of sex and age. Results: The literature search strategy produced 12,293 articles. The review process produced a final result of 23 studies. Our results estimate a significant positive relationship (r =.368 p < .001; 95% CI [.323, .412]) between attitudes toward violence and school violence in children and adolescents. Conclusions: This study allows us to quantify with an adequate degree of specificity the attitude-behavior relationship in the school context. These results may facilitate future researchers to design programs that address this specificity in order to improve school climate. More research is needed using validated instruments to further specify the type of attitudes that have the greatest influence on the manifestation of school violence.
