In vitro quantitative comparison of erosive potential of infant mouthwashes on glass ionomer cement

2018

Background The widespread use of mouthwashes, specially in children, is a concern, since the long-term use may modify the topography of dental materials. However, this process still unclear regarding the wear related to infant mouthwashes on glass ionomer cement. Thus, the purpose of this investigation was evaluate the erosive potential of infant mouthwashes on glass ionomer cement specimens. Material and methods Forty round-shaped specimens were divided into 4 groups (N=10) and submitted to erosive cycling for 15 days, being exposed 2X/day in the following children's active agents mouthwash solutions: G1- cetylpyridinium chloride, G2- xylitol and triclosan and G3 - Malva sylvestris and xyl…

Development and Preliminary Validation of a Sport-Specific Self-Report Measure of Identity Foreclosure

2021

A sport-specific, self-report measure of identity foreclosure was developed through a systematic process that included item pool generation, expert review, administration of items to a development sample of intercollegiate student athletes (N = 326), item evaluation, and administration of scales to validation samples of intercollegiate student athletes (N = 322, N = 54, and N = 64, respectively). The process yielded two four-item scales reflecting commitment to the occupational identity of athlete and one 4-item scale reflecting active exploration of roles other than that of athlete that (a) are internally consistent and temporally stable, (b) demonstrate preliminary factorial and convergen…

Abstract Understanding adolescent usage activity and experiences in web-based psychological intervention programs helps in developing universal programs that can be adopted for promotion of adolescent well-being and prevention of mental health problems. This study examined the usage activity, perceived usefulness (i.e., learning of mindfulness, acceptance and value-related skills), and program satisfaction of 157 Finnish ninth-grade adolescents, who participated in a school-based five-week universal acceptance and commitment therapy web intervention called Youth Compass. Individual and growth environment-related antecedents were measured before the five-week intervention, adolescents' usage…

Managing stress during the coronavirus disease 2019 pandemic and beyond: Reappraisal and mindset approaches

2020

The novel coronavirus disease 2019 (COVID‐19) pandemic is a global public health crisis of a scale not previously experienced in modern times (Kickbusch et al., 2020). Governmental ‘lockdown’ measures aimed at minimizing virus transmission including ‘stay at home’ orders, closure of businesses and places of congregation, and travel restrictions have had a substantive societal impact that permeates almost every facet of daily life (Gostin & Wiley, 2020; Shanafelt, Ripp, & Trockel, 2020). These widespread changes represent considerable sources of stress in the population and will have deleterious effects on mental and physical health going forward. As nations begin to emerge from ‘lockdown’, …

Do Large European Banks Differ in their Derivative Disclosure Practices? A Cross-country Empirical Study.

2019

Risk disclosure has strategic importance for the efficiency of financial markets and overall financial stability. It plays a pivotal role in strengthening market discipline and building trust to improve relationships with stakeholders in banking. Risk reporting has taken a growing importance in banking over the last years. The topic of this paper is derivative reporting in banking. The authors employ content analysis to conduct an empirical study on a sample of large European banks. The authors propose a hybrid scoring model for the assessment of derivative disclosure in banking institutions. The methodology employed in this research is able to capture a considerable amount of information b…

Unveiling the Role of Multiple blockholders: Evidence from Closely Held Firms.

2019

Research Question/Issue. This paper disentangles how the modes of ownership distribution among multiple blockholders and their heterogeneity shape principal–principal conflicts and, in turn, affect firm performance. The paper offers empirical evidence from a panel of Italian closely held firms over the period 2009–2014. Research Findings/Insights. We explore the principal–principal conflicts among blockholders across two distinct control structures. When a single blockholder controls the firm, principal–principal conflicts are shaped by the trade‐off between the alignment effect and the monitoring effect. In this scenario, we find that the relationship between the two largest blockholders' …

A New Branch-and-Cut Algorithm for the Generalized Directed Rural Postman Problem

2016

The generalized directed rural postman problem, also known as the close-enough arc routing problem, is an arc routing problem with some interesting real-life applications, such as routing for meter reading. In this article we introduce two new formulations for this problem as well as various families of new valid inequalities that are used to design and implement a branch-and-cut algorithm. The computational results obtained on test bed instances from the literature show that this algorithm outperforms the existing exact methods

Expecting justice: struggling with the indeterminate between ideals and practices

This commentary contextualizes Jacobs’ study as a contribution to a body of anthropological research concerned with theorizing the state, and more importantly concerned with closing the analytical ...

Spracherwerb und Kinderliteratur

2011

This paper argues for a close relationship of research into language acquisition and research into children’s literature. Because children’s literature is a specific input for many children, and because children’s literature basically is literature accommodated to the child’s needs and cognitive abilities, an interdisciplinary field of research emerges. The paper sketches several aspects of this field and points to already existing results as well as to future research.

Eight-Membered Rings With Two Heteroatoms 1,2

2022

The chapter titled “Eight-membered Rings with two Heteroatoms 1,2” deals with heterocine rings with two heteroatoms in a 1,2 relationship, namely 1,2-diazocine, 2H-1,2-oxazocine, 2H-1,2-thiazocine, 1,2-dioxocin, 1,2-oxathiocin and 1,2-dithiocin. This article covers the literature from 2007 to 2019 and reports the chemistry of uncondensed derivatives, heterocines fused to carbocycles and heterocycles, as well as bridged heterocines. As usual, in the case that a particular section is not mentioned, it means that no chemistry has been reported. In this article, the “Biosynthesis” paragraph was additionally introduced, since in the latest years the contribution of Nature to the synthesis of dih…
