Government debt, inflation dynamics and the transmission of fiscal policy shocks

We analyze the influence of the fiscal position on the transmission of government spending shocks in a New Keynesian model. We find that once we allow for positive levels of government debt in the steady state, the sign and the size of the fiscal multiplier depend strongly on the horizon at which the multiplier is evaluated. While the long-run effect of a fiscal policy innovation is typically of a similar order of magnitude as in Gali et al. (2007), short-run multipliers differ substantially. The reason for this non-monotonic behavior is the interaction between the dynamics of the inflation rate and the debt level in real terms, which is absent in standard models in which government debt is restricted to be equal to zero in the steady state

Vocational Satisfaction Among Roman Catholic Priests

The study was designed to investigate the theory that individuals who believe their environment to be compatible with their own self-concept will be happy and satisfied in that environment. Individuals who view their environment to be inconsistent with their self-concept will be dissatisfied and wish to leave that environment. A sample of Roman Catholic priests rated the concepts, self, ideal-self and the Church on an adapted semantic differential scale. Difference scores were cal-culated for each subject for three concept pairs: self-ideal-self, self-church, and ideal-self-church. In addition the subjects responded to three measures of adjustment; a sentence completion form, a standardized self-actualization scale, and a specially designed question-naire, they also answered a series of questions measuring their opinion of the church and their satisfaction with the priesthood. The subjects were subdivided into four developmental categories: developed, developing, underdeveloped and maldeveloped, on the basis of a clinical interview conducted by trained psychologists they were again divided into three groups according to large, small, or moderate self-ide•l-self difference scores. Pearson product-moment correlations were calculated between self-ideal-self differences and the three measures of adjustment and between the self-church and ideal-self-church differences and the measures of satisfaction with the Church and priesthood. When all the subjects were taken as a group only the sentence completion form as a measure of adjustment was substantially correlated with self-ideal-self differences. However, when the subjects were divided into the four developmental groups, the indicator of self-actualization was substantially correlated with self-ideal-self differences for the developing and maldeveloped subjects. When the subjects were divided into groups according to the degree of self-ideal difference, the subjects in the moderate difference group showed the strongest correlation with the measure of self-actualization. This supported pre-vious findings which suggested that both low and high self-ideal differences correlate less well with measures of adjustment than do the moderate self-ideal differences. When all of the subjects were taken together the self-church and ideal-self-church differences did not correlate well with any of the indicators of satisfaction with the priesthood. However, it was shown that developed priests who saw a similarity between themselves and the Church saw the church to be a more traditional institution, while maldeveloped subjects seeing a similarity between the self and the Church wanted the Church to be a more person-oriented agent for social reform

Fermi-edge Singularity in II-VI Semiconductor Resonant Tunneling Structures

We report on the observation of Fermi edge enhanced resonant tunneling transport in a II-VI semiconductor heterostructure. The resonant transport through a self assembled CdSe quantum dot survives up to 45 K and probes a disordered two dimensional (2D) like emitter which dominates the magnetic field dependence of the transport. An enhancement of the tunnel current through many particle effects is clearly observable, even without an applied magnetic field. Additional fine structure in the tunneling current suggests that while conventional Fermi edge singularity theory successfull reproduces the general features of the increased transmission, it is not adequate to describe all details of the current enhancement

Gastric Outlet Obstruction Palliation: A Novel Stent-Based Solution

Gastric outlet obstruction (GOO) after esophagectomy is a morbid outcome and significantly hinders quality of life for end-stage esophageal cancer patients. In the pre-stent era, palliation consisted of chemotherapy, radiation, tumor ablation, or stricture dilation. In the current era, palliative stenting has emerged as an additional tool; however, migration and tumor ingrowth are ongoing challenges. To mitigate these challenges, we developed a novel, hybrid, stent-based approach for the palliative management of GOO. We present a patient with esophageal cancer diagnosed with recurrent, metastatic disease 1 year after esophagectomy. She developed dehydration and intractable emesis, which significantly interfered with her quality of life. For palliation, we dilated the stenosis and proceeded with our stent-based solution. Using a combined endoscopic and fluoroscopic approach, we placed a 12-mm silicone salivary bypass tube across the pylorus, where it kinked slightly because of local tumor biology. To bridge this defect and ensure luminal patency, we placed a nitinol tracheobronchial stent through the silicone stent. Clinically, the patient had immediate relief from her pre-operative symptoms and was discharged home on a liquid diet. In conclusion, GOO and malignant dysphagia after esophagectomy are significant challenges for patients with end-stage disease. Palliative stenting is a viable option, but migration and tumor ingrowth are common complications. The hybrid approach presented here provides a unique solution to these potential pitfalls. The flared silicone tube minimized the chance of migration and impaired tumor ingrowth. The nitinol stent aided with patency and overcame the challenges of the soft tube. This novel strategy achieved palliation, describing another endoscopic option in the treatment of malignant GOO

Parents’ Perceived Similarity to Their Children, and Parents’ Perspective Taking Efforts: Associations of Cross-Informant Discrepancies with Adolescent Problem Behavior

Vierhaus M, Rueth J-E, Lohaus A. Parents’ Perceived Similarity to Their Children, and Parents’ Perspective Taking Efforts: Associations of Cross-Informant Discrepancies with Adolescent Problem Behavior. Frontiers in Psychology. 2016;7: 367.The main goal of this study is to provide empirical evidence for a theoretical mechanism underlying cross-informant discrepancies (CID), which occur between reports of different informants (e.g., children/adolescents and parents) of children’s/adolescents’ problem behavior. Studies comprehensively corroborate the existence of CID. However, an explanation of CID is rudimentary and inconsistent. Respective research often suffers from methodological problems and is often atheoretical. Addressing these critics, this study uses polynomial regression and is based on research on mind perception and anchoring-and-adjustment theory. It was assumed that higher CID are associated with parents’ perceived similarity to their children, whereas lower CID are related to parents’ perspective-taking efforts. Analyses were based on N = 168 parent–child dyads (children’s mean age: 12.50 years). Reports on problem behavior displayed substantial mean differences and medium-sized correlations. Polynomial regressions on CID partly supported the influence of parents’ perceived similarity and perspective taking efforts on CID. Results are discussed in the context of a possible theoretical fundament for CID

Emotion regulation among Chinese and German children and adolescents: a binational comparative study

peer reviewedEmotion regulation has been a central research topic in developmental psychology and psychopathology for several decades. Habitual use of adaptive (e.g., cognitive reappraisal) or maladaptive strategies (e.g., expressive suppression) may influence psychosocial adjustment in children and adolescents. Despite consensus on the influence of culture on emotion regulation, little is known about cultural differences in emotion regulation in children and adolescents. In this study, the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) was used and tested for its measurement invariance between Chinese and German children and adolescents. Cultural similarities and differences in the use of cognitive reappraisal and expressive suppression were examined, as well as the associations of these strategies with behavior problems and prosocial behavior. The sample consisted of 765 Chinese and 431 German students (Mage = 12.46 years, SD = 1.12). Multi-group confirmatory factor analysis revealed partial scalar measurement invariance of the ERQ-CA. A latent mean comparison showed more frequent use of both strategies in Chinese compared to German students. The results of the multi-group structural equation model showed similar patterns of relationships between emotion regulation strategies and youth behavior across groups. Cognitive reappraisal was associated with fewer behavior problems and more prosocial behavior, whereas expressive suppression was related to more behavior problems. In summary, the current findings indicate that the ERQ-CA allows comparisons of emotion regulation between Chinese and German children and adolescents. Furthermore, the relevance of the cultural context for emotion regulation and the promotion of adaptive regulation strategies is highlighted

S-100B as an extra selection tool for FDG PET/CT scanning in follow-up of AJCC stage III melanoma patients

Background and Objectives This current study assessed the value of S-100B measurement to guide fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scanning for detecting recurrent disease in stage III melanoma patients. Methods This study included 100 stage III melanoma patients in follow-up after curative lymph node dissection. Follow-up visits included physical examination and S-100B monitoring. FDG PET/CT scanning was indicated by clinical symptoms and/or elevated S-100B. Results Of 100 patients, 13 (13%) had elevated S-100B without clinical symptoms, of whom 7 (54%) showed disease evidence upon FDG PET/CT scanning. Twenty-six patients (26%) had clinical symptoms with normal S-100B and FDG PET/CT revealed metastasis in 20 (77%). Three patients had clinical symptoms and elevated S-100B, and FDG PET/CT revealed metastasis in all three (100%). Overall, FDG PET/CT scanning revealed metastasis in 30 of the 42 patients (71.4%). For seven recurrences, elevated S-100B prompted early detection of asymptomatic disease; 10% of all asymptomatic patients in follow-up, 23% of all patients with recurrent disease. Conclusion S-100B cannot exclude recurrent disease during follow-up of stage III melanoma. However, adding S-100B measurement to standard clinical assessment can guide FDG PET/CT scanning for detecting recurrent melanoma
