Declining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related questions. The project employs a harmonized approach to conduct within-country analyses that are combined for meaningful cross-country comparisons. The key lesson is that the choices of policy makers affect the incentive to work at older ages and these incentives have important effects on retirement behavior.
X-ray diffraction in the Bragg-Brentano configuration (“XRD”) is a very established method. However, experimental evidence concerning its significant information depth, i.e. microstructure components from which maximum depth can affect the information evaluated from the acquired diffraction pattern, are scarce in the scientific literature. This depth is relevant to all XRD measurements performed on compact samples, especially layered composites and samples showing a crystallographic texture evolution. This article provides experimentally determined upper and lower limits to the significant information depth: XRD patterns acquired from a compact crystal layer through a layer of compact, amorphous glass indicate that the significant information depth of XRD using Cu Kα1 and Kα2 radiation is very likely larger than 48 μm, but smaller than 118 μm, in a material of the composition Mg2Al4Si5O18 with a density of ca. ~2.6 g/cm3. The depth of 48 μm correlates to the depth larger than the layer of material from which 90% of the reflected X-rays originate at 2Θ = 25.8°.
Posttraumatic growth (PTG) refers to positive psychological changes resulting from individuals’ inner struggles with traumatic events such as life-threatening illness. Although palliative care patients are confronted with their own mortality, little is known about their PTG experience. This study investigates whether PTG is an empirically relevant concept for palliative patients by assessing the prevalence and areas of growth, and examining associations with psychological distress and quality of life.
Methods
Participants were recruited in Switzerland. Using validated questionnaires, we assessed PTG (Posttraumatic Growth Inventory, PTGI), psychological distress (Hospital Anxiety and Depression Scale), and quality of life (McGill-Quality of Life Questionnaire – Revised). We performed descriptive analyses, Spearman correlations, and linear regressions.
Results
Fifty-five patients completed the PTGI, 44% of whom experienced no/low growth, 47% moderate growth, and 9% high/very high growth. Participants experienced the greatest positive changes in terms of appreciating life and relating to others. We found significant negative bivariate correlations between PTG and psychological distress (r = −0.33) and between PTG and depression (r = −0.47). Linear regressions showed that PTG is associated with depression (β = −0.468; p = 0.000), but not with anxiety or quality of life (adjusted R2 = 0.219).
Significance of results
Over half of our patients experienced moderate to very high growth, indicating that PTG is an empirically relevant psychological process in palliative care. PTG is associated with lower levels of depression, possibly as those experiencing growth are more able to process past traumas and build a more positive outlook on one's life and self. By contrast, the relative independence of anxiety and PTG points to the likely coexistence of positive and negative psychological responses to trauma. The lack of association between PTG and quality of life points to the uniqueness of the PTG concept in capturing how people access deeper meaning and greater appreciation of life along the path toward posttraumatic self-reconstruction.
Digitalization in the legal domain is an amazing example of the way information technology (IT) can displace or enrich typically human tasks. Fueled by the recent progress in artificial intelligence (AI) (big data, machine learning, natural language processing, etc.), this phenomenon of digitalization affects more and more legal tasks and functions. Effective examples of digitalization in the legal domain are very diverse, ranging from exploration of patent classifications1 to prediction of legal cases’ outcomes (e.g., anticipation of foreseeable damages from an action).2 One can also mention e-discovery,3 as well as the digitalization of the organization and review of legal documents.4
Dispatchers should be trained to interrogate bystanders with strict protocols to elicit information focused on recognizing cardiac arrest and should provide telephone cardiopulmonary resuscitation (CPR) instructions in all cases of suspected cardiac arrest. While an objective assessment of training outcomes is needed, there is no performance assessment scale for simulated dispatcher-assisted CPR.
Study Objective:
The aim of the study was to create a valid and reliable performance assessment scale for simulated dispatcher-assisted CPR.
Methods:
In this prospective, randomized, controlled, multi-centric simulation-based trial (registration number TCTR20210130002), the scale was developed according to the European Resuscitation Council (ERC) and American Heart Association (AHA) Guidelines 2015 and revised by experts. The performance of 48 dispatchers’ telephone-CPR and of 48 bystanders carrying out CPR on a manikin was assessed by two independent evaluators using the scale and using a SkillReporter (PC) software to provide CPR objective performance. Continuous variables were described as mean (SD) and categorical variables as numbers and percentage (%). Comparative analysis between two groups used a Student t-test or a non-parametric test of Mann-Whitney. The internal structure of the scale was evaluated, including internal consistency using α Cronbach coefficient, and reproducibility using intraclass correlation coefficient (ICC) and linear correlation coefficient (R2) calculation.
Results:
The scale included three different parts: two sections for dispatchers’ (32 items) and bystanders’ CPR performance (15 items) assessment, and a third part recording times. There was excellent internal consistency (α Cronbach coefficient = 0.77) and reproducibility (ICC = 0.93; R² = 0.86). For dispatchers’ performance assessment, α Cronbach coefficient = 0.76; ICC = 0.91; R2 = 0.84. For bystanders’ performance assessment, α Cronbach coefficient = 0.75; ICC = 0.93; R2 = 0.87. Reproducibility was excellent for nine items, good for 19 items, and moderate for 19 items. No item had poor reproducibility. There was no significant difference between dispatch doctors’ and medical dispatch assistants’ performances (33.0 [SD = 4.7] versus 32.3 [SD = 3.2] out of 52, respectively; P = .70) or between trained and untrained bystanders to follow the instructions (14.3 [SD = 2.0] versus 13.9 [SD = 1.8], respectively; P = .64). Objective performance (%) was significantly higher for trained bystanders than for untrained bystanders (67.4 [SD = 14.5] versus 50.6 [SD = 19.3], respectively; P = .03).
Conclusion:
The scale was valid and reliable to assess performance for simulated dispatcher-assisted CPR. To the authors’ knowledge, no other valid performance tool currently exists. It could be used in simulated telephone-CPR training programs to improve performance.
There is a growing literature in support of the effectiveness of task-shared mental health interventions in resource-limited settings globally. However, despite evidence that effect sizes are greater in research studies than actual care, the literature is sparse on the impact of such interventions as delivered in routine care. In this paper, we examine the clinical outcomes of routine depression care in a task-shared mental health system established in rural Haiti by the international health care organization Partners In Health, in collaboration with the Haitian Ministry of Health, following the 2010 earthquake.
Methods
For patients seeking depression care betw|een January 2016 and December 2019, we conducted mixed-effects longitudinal regression to quantify the effect of depression visit dose on symptoms, incorporating interaction effects to examine the relationship between baseline severity and dose.
Results
306 patients attended 2052 visits. Each visit was associated with an average reduction of 1.11 in depression score (range 0–39), controlling for sex, age, and days in treatment (95% CI −1.478 to −0.91; p < 0.001). Patients with more severe symptoms experienced greater improvement as a function of visits (p = 0.04). Psychotherapy was provided less frequently and medication more often than expected for patients with moderate symptoms.
Conclusions
Our findings support the potential positive impact of scaling up routine mental health services in low- and middle-income countries, despite greater than expected variability in service provision, as well as the importance of understanding potential barriers and facilitators to care as they occur in resource-limited settings.
Conscious patients undergoing regional anaesthesia are able to interact with caregivers and indicate when they are feeling pain and/or anxiety during surgery. Unconscious patients on the other hand, not only in the operating room but also in intensive care, need antinociception when a nociceptive stimulus is applied. In these patients, the dose of antinociceptive drugs cannot be adjusted or the effect of locoregional anaesthesia supplementing general anaesthesia cannot be determined by simply asking the patient. Thus, the clinician needs to rely on monitors of the nociception/antinociception (N/AN) balance to be able to provide adequate, that is personalized, antinociception.
With the aim of solving in a four dimensional phase space a multi-scale Vlasov-Poisson system, we propose in a Particle-In-Cell framework a robust time-stepping method that works uniformly when the small parameter vanishes. As an exponential integrator, the scheme is able to use large time steps with respect to the typical size of the solution’s fast oscillations. In addition, we show numerically that the method has accurate long time behaviour and that it is asymptotic preserving with respect to the limiting Guiding Center system.
The economic and financial crisis has meant sizeable employment losses that resulted from different adjustment mechanisms in domestic firms and multinational companies. This may be due to either production plant closures or downsizing by firms that remain active. This paper evaluates the importance of both phenomena for multinational and domestic firms in Belgium over the period preceding the crisis (1997-2008), using a firm-level dataset. Our results reveal that multinational enterprises tend to leave the local market more frequently than domestic firms with comparable firm and sector characteristics. Further, multinational incumbents face employment adjustment costs for white-collar workers that are around half of those borne by domestic firms. In sum, our findings suggest that multinational firms are more flexible in terms of plant location as well as in terms of employment adjustment. However, before the crisis, foreign multinationals created more jobs on average than other types of firms.
This paper presents the evaluation of oxidizing and reducing plasmas for post etch pore-sealing treatments during patterning of interconnections in a porous Ultra Low-k (ULK) material. Morphological and chemical characterizations as well as electrical results (resistance, capacitance, leakage, yield) are presented for both single and dual-damascene integrations.
