The Effect of Inner Mobility of Shops on Tax Revenue
In this note we consider a simple model of a service sector. In this service sector there are two types of shops, each offering distinct services at differential prices with fixed cost possibly being also unequal. When the decrease of customers is experienced by one of these two types, not both, then having less profits, those shops belonging to the damaged type can shift to the other type, thus alleviating losses on the whole. This can also mitigate the effect on tax revenue. The typical sector which the authors have in mind is that of pubs and restaurants where two types are the 'first-rate (more expensive with more services)' and the 'popular' class. Based on this model, we conduct an elementary comparative statics analysis. Most results are natural consequences, which can be inferred without using equations. And yet we supply proofs based upon equations and inequalities. Our main result is that with migration between two groups, the sector may incur less loss against the decrease in customers, especially that in the first-rate class. This means the effect on tax revenue is also milder with shiftability. Our model in this note is quite restrictive because the size of customers is exogenously given and does not respond to price differentials. Moreover in the analysis of comparative statics, the number of shops is fixed with no entry and no bankruptcy. These constraints should be removed in a more general framework
利益による償還株式の消却についての一考察
"商法第222条1項に規定するところの,利益による償還株式の消却によって,資本金は名実ともに滅少しないとするのが現行の通説である。しかしながら,このような見解は,償還株式の消却によって,償還されない株式を保有する株主(残留株主)の株主持分は,一方において利益持分が滅少し,他方において資本持分が増加する点からみて疑問を抱かざるを得ない。結局,利益による償還株式の消却は,一方における資本金の払戻しと,他方における残留株主による利益の資本組入れの形での追加出資を伴う措置であり,後者に対して新株を発行しないために形式的に株式の消却,つまり特定の発行済株式を消滅せしめる措置にすぎないのではなかろうかとする疑問を提起した。
株式、株主有限責任、資本金および株主の危険負担の相互関係についての一考察
現行の株式会社における基本的特質としての株式、株主有限責任の制度および資本金の制度を、相互に内在する論理的関連性の観点から考察を加えた。まず、現行株式会社においては会社の成立、存立、維持および運営のあらゆる側面において「株式」は本源的要素技術と名付けるに値するほどの多種、多様な機能、役割を果たしていることを述べた。ついで本来の意味では株主と会社債権者との間に成立する法律関係としての株主有限責任の制度は、これを担保するところの資本金の制度に支えられて原始株主の出資後も依然として内在的、実体的には存在しているのではなかろうかという私見を述べた。最後に株式のもつ財産的価値を強調して、会社が経営不振に陥って承継株主を含む株主の有する株式の経済価値が原始株主の出資額もしくは株主の資本持分を下回り、最悪の状況ではゼロとなった場合には、株主有限責任に内在する危険負担者としての株主の地位、立場が具体化、顕在化して危険を負担し、不利益を蒙るのではなかろうかとする私見を開陳した
Case of 24-week Fetus Delivered from Mother on Life Support with Brain-death from Suicide Attempt: Ethical Issues Associated with Severe Complications
Advances in critical care medicine have made it possible to sustain vital organ systems in brain-dead patients. One clinical scenario besides donor organ retrieval in which a benefit may be gained from continuing life support is pregnancy. A pregnant woman in her late 30ʼs at 23 weeks gestation exhibiting worsening depression was referred to the Department of Psychiatry. One day after admission she attempted suicide by hanging and suffered a cardiopulmonary arrest. A fetal heart beat and fetal motion was confirmed immediately after resuscitation. Three days after admission, an emergency Cesarean section (CS) was performed because of her unstable hemodynamic situation. The baby was born and the mother died after delivery. The baby presented neurological complications. Such a case should be managed collaboratively among professional experts in several medical teams. Consensus and recommendations for the management of similar scenarios may also be adjusted
Study protocol for a multi-center, randomized controlled trial to develop Japanese denture adhesive guidelines for patients with complete dentures : the Denture Adhesive Guideline trial : study protocol for a randomized controlled trial
Background: Denture adhesives, characterized as medical products in 1935 by the American Dental Association, have been considered useful adjuncts for improving denture retention and stability. However, many dentists in Japan are hesitant to acknowledge denture adhesives in daily practice because of the stereotype that dentures should be inherently stable, without the aid of adhesives. The aim of this study is to verify the efficacy of denture adhesives to establish guidelines for Japanese users. The null hypothesis is that the application of denture adhesives, including the cream and powder types, or a control (isotonic sodium chloride solution) would not produce different outcomes nor would they differentially improve the set outcomes between baseline and day 4 post-application.
Methods: This ten-center, randomized controlled trial with parallel groups is ongoing. Three hundred edentulous patients with complete dentures will be allocated to three groups (cream-type adhesive, powder-type adhesive, and control groups). The participants will wear their dentures with the denture adhesive for 4 days, including during eight meals (three breakfasts, two lunches, and three dinners). The baseline measurements and final measurements for the denture adhesives will be performed on the first day and after breakfast on the fourth day. The primary outcome is a general satisfaction rating for the denture. The secondary outcomes are denture satisfaction ratings for various denture functions, occlusal bite force, resistance to dislodgement, masticatory performance, perceived chewing ability, and oral health-related quality of life. Between-subjects comparisons among the three groups and within-subjects comparisons of the pre- and post-intervention measurements will be performed. Furthermore, a multiple regression analysis will be performed. The main analyses will be based on the intention-to-treat principle. A sample size of 100 subjects per group, including an assumed dropout rate of 10 %, will be required to achieve 80 % power with a 5 % alpha level.
Discussion: This randomized clinical trial will provide information about denture adhesives to complete denture wearers, prosthodontic educators, and dentists in Japan. We believe this new evidence on denture adhesive use from Japan will aid dentists in their daily practice even in other countries
Sequential therapies after atezolizumab plus bevacizumab or lenvatinib first-line treatments in hepatocellular carcinoma patients
Introduction: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab.Materials and methods: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line.Results: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6 months) and atezolizumab plus bev-acizumab first-line (15.7 months; p = 0.12; hazard ratio [HR] = 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who under-went trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8 months, p < 0.01; HR = 0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0 months) and those who under-went TACE (15.9 months) had a significative longer OS than patients treated with sorafenib (14.2 months; respectively, p = 0.01; HR = 0.45, and p < 0.05; HR = 0.46).Conclusion: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy
Adverse Events as Potential Predictive Factors of Activity in Patients with Advanced HCC Treated with Atezolizumab Plus Bevacizumab
Background In the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors. Objective This retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting. Patients and methods The study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea). Results Of the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G >= 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G >= 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G >= 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G >= 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival. Conclusions As demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab
