Young adults’ subjective and objective risk attitude in financial decision making

Purpose The purpose of this paper is to derive the determinants of young adults’ subjective and objective risk attitude in theoretical and real-world financial decisions. Furthermore, a comparison of the factors that influence young adults’ and older adults’ risk attitude is provided. Design/methodology/approach The paper relies on an experimental setting and a cross-sectional field study using data of the German central bank’s (Deutsche Bundesbank) PHF-Survey. Findings Young adults’ objective risk aversion is not constant but increases with stake sizes. Furthermore, young adults’ subjective risk attitude is a better predictor for their objective risk attitude than a set of commonly employed socio-demographics and economics like age or income. Moreover, young adults’ subjective risk attitude works as a mediator for the influence of their investable financial wealth on their objective risk attitude. Although young adults’ subjective risk attitude shows a gender effect, the influence of young adults’ gender on their objective risk attitude decreases with higher stake sizes. Compared to older adults, young adults generally show a similar degree of subjective risk aversion. However, due to stronger financial restrictions, young adults show a higher degree of objective risk aversion. Originality/value Although individuals’ financial outcomes depend on the financial behavior established in young adulthood, there is no study that simultaneously analyzes the determinants of young adults’ subjective and objective risk attitude in real-world financial decisions with a focus on young adults as a separate age group. The paper closes this gap in literature and additionally provides a comparison of the subsamples of young adults and older adults. The analysis in this paper reveals that young adults’ lower engagement in financial markets is primarily driven by their tight budget and not by a fundamental different subjective risk attitude.
The role of different types of instrumentality in motivation, study strategies, and performance: know why you learn, so you'll know what you learn!

BACKGROUND Two theories in the field of motivation and achievement, namely the future time perspective theory and goal theory, result in conflicting recommendations for enhancing students' motivation, because of their differential emphasis on the task at hand and on the future consequences of a task. AIMS We will present a framework consisting of four types of instrumentality that combines both perspectives. The implications of those different types for goal orientation, motivation, cognitive strategies, study habits and performance are investigated. SAMPLES Participants were a group of 184 first-year nurse students with ages ranging from 18 to 45 years. METHODS Questionnaires were administered that measured instrumentality, goal orientation, motivation, deep and surface level learning strategies, study habits, and a manipulation check. At the end of the year, exam scores were collected. RESULTS The results showed that different types of instrumentality are related differently to the motivational, cognitive and achievement measures. Being internally regulated and perceiving the utility of the courses resulted both in a more adaptive goal orientation and higher intrinsic motivation, which led to the use of more adaptive cognitive strategies and to better study habits, which ultimately enhanced performance. Linking performance to extrinsic rewards and not seeing the utility of the course for the future yielded the opposite pattern. CONCLUSIONS Type of instrumentality has indeed a differential influence on motivational, cognitive, and behavioural variables.
The clinical success of zirconia-based crowns: a systematic review.

PURPOSE This review aimed to evaluate the documented clinical success of zirconia based crowns in clinical trials. MATERIALS AND METHODS Electronic databases were searched for original studies reporting on the clinical performance of tooth- or implant-supported zirconia-based crowns, including PubMed, Cochrane Library, and Science Direct. The electronic search was complemented by manual searches of the bibliographies of all retrieved full-text articles and reviews as well as a hand search of the following journals: International Journal of Prosthodontics, Journal of Oral Rehabilitation, International Journal of Oral & Maxillofacial Implants, and Clinical Oral Implants Research. RESULTS The search yielded 3,216 titles. Based on preestablished criteria, 42 full-text articles were obtained. While 16 studies fulfilled the inclusion criteria, only 3 randomized controlled trials were reported. Seven studies reported on tooth-supported and 4 on implant-supported crowns, and 5 studies reported on both types of support. Ten studies on tooth-supported and 7 on implant supported crowns provided sufficient material for statistical analysis. Life table analysis revealed cumulative 5-year survival rates of 95.9% for tooth-supported and 97.1% for implant-supported crowns. For implant-supported crowns, the most common reasons for failure were technical (veneering material fractures). For tooth-supported crowns, technical (veneering material fractures, loss of retention) and biologic (endodontic/ periodontic) reasons for failure were equally common. The most common complications for implant-supported crowns were veneering material fractures and bleeding on probing. For tooth-supported crowns, the most common complications were loss of retention, endodontic treatment, veneering material fractures, and bleeding on probing. CONCLUSION The results suggest that the success rate of tooth-supported and implant-supported zirconia-based crowns is adequate, similar, and comparable to that of conventional porcelain-fused-to-metal crowns. These results are, however, based on a relatively small number of studies, many that are not controlled clinical trials. Well-designed studies with large patient groups and long follow-up times are needed before general recommendations for the use of zirconia-based restorations can be provided.
Segmentation of tourists in the heritage site of Cuenca, Ecuador

This paper contributes to presenting the relationship that exists in a certain tourism destination between the World Heritage Site (WHS) and the Intangible Cultural Heritage (ICH), showing a segmentation of the tourists in Cuenca, Ecuador. The methodology used in this research has been the application of a multivariate technique of grouping items and the realisation of a post-hoc single-variate ANOVA analysis. The results show the existence of three motivational dimensions for visiting the city, two of a cultural nature and the third being hedonic. Depending on the motivation, four types of tourists are identified: the hedonic ICH-WHS tourist, the hedonic WHS tourist, the hedonic tourist and the ICH-WHS tourist. This research reinforces this theme, in a geographic area, Latin America, characterised by a recognised WHS but still little studied in the scientific literature.
Mobile Phone Sensor Correlates of Depressive Symptom Severity in Daily-Life Behavior: An Exploratory Study

Background Depression is a common, burdensome, often recurring mental health disorder that frequently goes undetected and untreated. Mobile phones are ubiquitous and have an increasingly large complement of sensors that can potentially be useful in monitoring behavioral patterns that might be indicative of depressive symptoms. Objective The objective of this study was to explore the detection of daily-life behavioral markers using mobile phone global positioning systems (GPS) and usage sensors, and their use in identifying depressive symptom severity. Methods A total of 40 adult participants were recruited from the general community to carry a mobile phone with a sensor data acquisition app (Purple Robot) for 2 weeks. Of these participants, 28 had sufficient sensor data received to conduct analysis. At the beginning of the 2-week period, participants completed a self-reported depression survey (PHQ-9). Behavioral features were developed and extracted from GPS location and phone usage data. Results A number of features from GPS data were related to depressive symptom severity, including circadian movement (regularity in 24-hour rhythm; r=-.63, P=.005), normalized entropy (mobility between favorite locations; r=-.58, P=.012), and location variance (GPS mobility independent of location; r=-.58, P=.012). Phone usage features, usage duration, and usage frequency were also correlated (r=.54, P=.011, and r=.52, P=.015, respectively). Using the normalized entropy feature and a classifier that distinguished participants with depressive symptoms (PHQ-9 score ≥5) from those without (PHQ-9 score <5), we achieved an accuracy of 86.5%. Furthermore, a regression model that used the same feature to estimate the participants’ PHQ-9 scores obtained an average error of 23.5%. Conclusions Features extracted from mobile phone sensor data, including GPS and phone usage, provided behavioral markers that were strongly related to depressive symptom severity. While these findings must be replicated in a larger study among participants with confirmed clinical symptoms, they suggest that phone sensors offer numerous clinical opportunities, including continuous monitoring of at-risk populations with little patient burden and interventions that can provide just-in-time outreach.

Cytokine-induced release of ceramide-enriched exosomes as a mediator of cell death signaling in an oligodendroglioma cell line[S]

Th1 pro-inflammatory cytokines, i.e., TNF-α and IFN-γ, in combination are known to induce cell death in several cell types, including oligodendrocytes, but the mechanism of their synergistic cytotoxicity is unclear. Although ceramide (Cer) has been implicated in cytokine- and stress-induced cell death, its intracellular levels alone cannot explain cytokine synergy. We considered the possibility that Cer released as part of extracellular vesicles may contribute to cytokine-induced synergistic cell death. Using a human oligodendroglioma (HOG) cell line as a model, here we show that exosomes derived from TNF-α-treated “donor” cells, while being mildly toxic to fresh cultures (similar to individual cytokines), induce enhanced cell death when added to IFN-γ-primed target cultures in a fashion resembling the effect of cytokine combination. Further, the sphingolipid profiles of secreted exosomes, as determined by HPLC-MS/MS, revealed that the treatment with the cytokines time-dependently induced the formation and exosomal release, in particular of C16-, C24-, and C24:1-Cer species; C16-, C24-, and C24:1-dihydroCer species; and C16-, C24-, and C24:1-SM species. Finally, exogenous C6-Cer or C16-Cer mimicked and enhanced the cytotoxic effects of the cytokines upon HOG cells, thereby supporting the cell death-signaling role of extracellular Cer.
Attending to and Remembering Tactile Stimuli: A Review of Brain Imaging Data and Single-Neuron Responses

Summary Clinical and neuroimaging observations of the cortical network implicated in tactile attention have identified foci in parietal somatosensory, posterior parietal, and superior frontal locations. Tasks involving intentional hand–arm movements activate similar or nearby parietal and frontal foci. Visual spatial attention tasks and deliberate visuomotor behavior also activate overlapping posterior parietal and frontal foci. Studies in the visual and somatosensory systems thus support a proposal that attention to the spatial location of an object engages cortical regions responsible for the same coordinate referents used for guiding purposeful motor behavior. Tactile attention also biases processing in the somatosensory cortex through amplification of responses to relevant features of selected stimuli. Psychophysical studies demonstrate retention gradients for tactile stimuli like those reported for visual and auditory stimuli, and suggest analogous neural mechanisms for working memory across modalities. Neuroimaging studies in humans using memory tasks, and anatomic studies in monkeys support the idea that tactile information relayed from the somatosensory cortex is directed ventrally through the insula to the frontal cortex for short-term retention and to structures of the medial temporal lobe for long-term encoding. At the level of single neurons, tactile (such as visual and auditory) short-term memory appears as a persistent response during delay intervals between sampled stimuli.
Vitamin B intake and status in healthy Havanan men, 2 years after the Cuban neuropathy epidemic

A prospective epidemiological study was carried out over 1 year to evaluate vitamin B complex dietary intake and status in Cuba, 2 years after the Cuban neuropathy epidemic of 1993. Of the 199 healthy middle-aged men selected, 141 completed the study. Volunteers were followed up every 3 months for 1 year. Dietary intake and status of thiamin, riboflavin, vitamin B6, folate and vitamin B12 were assessed each time. The dietary intake of vitamin B complex was low, particularly in June and July (folate), and October (thiamin). A deficient status was observed for vitamin B complex, except for vitamin B6. Vitamin B complex intake and status varied over the year. However, dietary intake and status were poorly related. The results prove that healthy Cuban men represent a vulnerable population in terms of vitamin B complex status and stress the necessity to both promote preventive multivitamin supplementation and produce local food rich in vitamin B complex.
Revisiting Interregional Wage Differentials: New Evidence from Spain with Matched Employer-Employee Data

This study examines wage differences across Spain's regions along the entire wage distribution based on matched employer-employee microdata from 2006 to 2014. Unlike previous studies, we control for differences in regional purchasing power parities, which are very large in practice. Although many of the raw wage differences observed are explained by differences between regional productive structures and, to a lesser extent, in labour forces, noteworthy regional differences net of composition effects remain after controlling for a broad set of individual and firm characteristics. Unexplained wage differences are generally very similar throughout the wage distribution and are strongly persistent over time, despite significant changes in both economic cycle and labour regulations that occurred in Spain during the examined period. This evidence suggests the presence of common mechanisms in the generation of regional wage differentials that affect the whole labour force and that are strongly persistent over time, which is consistent with a key role of collective bargaining
FOLLOW-UP GENOTOXICOLOGICAL MONITORING OF NURSES HANDLING ANTINEOPLASTIC DRUGS

Most of the antineoplastic drugs used in the treatment of tumors are carcinogenic to humans. Hospital nurses are often subject to possible occupational carcinogen exposure. Exposure may occur during handling and administration of infusion solutions containing cytostatics. A genotoxicological monitoring system to detect genotoxic changes was developed in our laboratory, helping to improve working conditions and subserving primary prevention. Multiple-endpoint follow-up genotoxicological monitoring was performed in peripheral blood lymphocytes (PBLs) among 4 groups of 95 nurses (152 investigations) occupationally exposed to cytostatics. The results were compared to those of historical and industrial controls. The genotoxicological endpoints were the determination of the frequency of sister chromatid exchanges (SCEs) and the cells with high-frequency SCEs (HFC), the frequency of structural and numerical chromosome aberrations, and the measurement of ultraviolet-light-induced unscheduled DNA-repair synthesis (UDS). In Hospital 1, where nurses worked without a safety cabinet, the percentage of cells with chromosome aberrations (AC) was significantly higher than that of the controls. In Hospital 2, where nurses used inadequate safety cabinets (with horizontal airflow), significantly elevated levels of AC, SCE, HFC, and UDS were detected. During follow-up, in Hospital 2 at the time of the second investigation AC was still significantly higher, although safety conditions had been improved. The results indicate the presence of genotoxic damage in hospital nurses working with no or inadequate safety equipment. In Hospitals 3 and 4 where nurses using biological safety cabinets, the results were lower than those in the previous two groups. In Hospital 3 in the first year of the study AC was as at the level of industrial controls. During follow-up in the course of the repeated investigations a fluctuation in AC above the control level and an increase in HFC in yr 4 and 6 of the study were observed. In this group, the fluctuation in AC and HFC during the study points to the possibility of genotoxic exposure with cytostatics despite of the use of suitable safety cabinets, drawing attention to other possible routes of exposure. In Hospital 4, both AC and HFC were elevated. These data corroborate the need to maintain safety measures to avoid exposure, and the necessity of intervention in the case of exposure when using and handling hazardous carcinogenic agents. The results also indicate a certain expression time for genotoxic changes, which can lead to late somatic mutations as well as to a possible higher risk of cancer.
Hospital Episodes and Physician Visits: The Concordance Between Self-Reports and Medicare Claims

Background:Health services use typically is examined using either self-reports or administrative data, but the concordance between the 2 is not well established. Objective:We evaluated the concordance of hospital and physician utilization data from self-reports and claims data, and identified factors associated with disagreement. Methods:We performed a secondary analysis on linked observational and administrative data. A national sample of 4310 respondents who were 70 years old or older at their baseline interviews was used. Self-reported and Medicare claims-based hospital episodes and physician visits for 12 months before baseline were examined. Kappa statistics were used to evaluate concordance, and multivariable multinomial logistic regression was used to identify factors associated with overreporting (self-reports > claims), underreporting (self-reports < claims), and concordant-reporting (self-reports ∼ claims). Results:The concordance of hospital episodes was high (κ = 0.767 for the 2 × 2 comparison of none vs. some and κ = 0.671 for the 6 × 6 comparison of none, 1, …, 4, or 5 or more), but concordance for physician visits was low (κ = 0.255 for the 2 × 2 comparison of none versus some and κ = 0.351 for the 14 × 14 comparison of none, 1, ., 12, and 13 or more). Multivariable multinomial logistic regression indicated that over-, under-, and concordant-reporting of hospital episodes was significantly associated with gender, alcohol consumption, arthritis, cancer, heart disease, psychologic problems, lower body functional limitations, self-rated health, and depressive symptoms. Over-, under-, and concordant-reporting of physician visits were significantly associated with age, gender, race, living alone, veteran status, private health insurance, arthritis, cancer, diabetes, hypertension, heart disease, lower body functional limitations, and poor memory. Conclusions:Concordance between self-reported and claims-based hospital episodes was high, but concordance for physician visits was low. Factors significantly associated with bidirectional (over- and underreporting) and unidirectional (over- or underreporting) error patterns were detected. Therefore, caution is advised when drawing conclusions based on just one physician visit data source.
Psychiatric characteristics of 100 nonviolent suicide attempters in Hungary

Background: Previous international and Hungarian studies have shown that around 90% of persons making suicide attempts had at least one current mental disorder. The aim of this study was to investigate the current prevalence of DSM-IV Axis I psychiatric diagnoses among nonviolent suicide attempters in Budapest, Hungary. Methods: Using a structured interview (Mini International Neuropsychiatric Interview) determining DSM-IV Axis I diagnoses, the authors examined 100 consecutively contacted nonviolent suicide attempters (68 females and 32 males), aged between 14 and 66 (mean: 36.3 years). Results: A total of 64% of the subjects were repeated attempters, and the most common method was drug overdose (96%), in 21% of cases in combination with alcohol ingestion. A total of 92% of the attempters had at least one current DSM-IV Axis I psychiatric diagnosis. In 87% it was depressive disorder (59% unipolar major depression, 14% bipolar II depression and 12% bipolar I depression, 2% dysthymic disorder), in 46% anxiety disorders, in 27% substance-use disorder and in 2% psychotic disorder. Sixty percent of the attempters received two or more current Axis I diagnoses (35% depressive + anxiety disorder only, 15% depressive + substance-related disorder only, and 10% depressive + anxiety + substance-related disorder). Limitations: Nonviolent suicide attempters are not representative of all persons with attempted suicide and subthreshold Axis I diagnoses were not investigated. Conclusion: This study supports previous international and Hungarian findings on the high prevalence and comorbidity of Axis I mental disorders among persons with recent nonviolent suicide attempt.
A comparison of cellular vehicle-to-everything and dedicated short range communication

Vehicle to Everything (V2X) communication, which involves vehicles disseminating information about its type, location and movement are known to help increasing road safety. At physical layer, there are two main solutions: 1) Dedicated Short Range Communication, which is based on IEEE 802.11p standard and 2) Cellular V2X, which is a recent development in 3GPP LTE standard to support V2X use case. In this paper, we provide our comparison of the performance of the two aforementioned technologies at both link level and system level. Based on this study, one can see that Cellular V2X provides significant improvement over Dedicated Short Range Communication in terms of communication range, without suffering in other aspects. This improvement is equivalent to longer reaction time and more lives saved in the road.
