This paper examines global recessions as a cascade phenomenon. In other words, how recessions arising within one or more countries might percolate across a network of connected economies. An agent based model is set up in which the agents are Western economies. A country has a probability of entering recession in any given year and one of emerging from it the next. In addition, the agents have ...

This paper values the option of a firm to downscale production in recessionary times. The regulator allows downscaling as long as the recession lasts. The end of the recession is modelled via a Poisson process. We show that the disinvestment timing is affected by two contrary effects. First, when the probability increases that the recession will be over soon, the firm will disinvest sooner, bec...

BACKGROUND Females are generally more motivated with regard to oral hygiene practices and thus brush their teeth more frequently than males. OBJECTIVE To determine the prevalence of gingival recession, oral hygiene status, oral hygiene practices and associated factors in women attending a maternity ward in Tanzania. DESIGN Cross-sectional descriptive study. SETTING Maternity ward of Muhim...

BACKGROUND Some of the country's highest rates of morbidity and mortality from cardiovascular disease are found in lower-income black communities in the rural Southeast. Research suggests these disparities originate in the early decades of life, and partly reflect the influence of broader socioeconomic forces acting on behavioral and biological processes that accelerate cardiovascular disease p...

The purpose of the study was the evaluation of the dental plaque and the influence of determined hygienic factors on gingival recession occurrence in 455 students of The Medical University of Bialystok. All the subjects were examined in artificial light, with the use of the probe, mirror, and parodontometer. The distribution of stained dental deposits were estimated with the use of the plaque i...

INTRODUCTION Gingival recession is an unsightly condition due to root exposure. It can lead to dental hypersensitivity, root caries, and tooth loss. OBJECTIVE To determine the influence of different clinical and periodontal parameters on the severity of gingival recession evaluated at four periods: initial, 6, 12, and 18 months of follow-up. MATERIAL AND METHODS Forty patients with gingival...

statement of problem: treatment of gingival recession defect and covering denuded root surfaces is one of the goals in periodontal therapy and several surgical techniques have been suggested in this field.purpose: the aim of this study was to perform a comparison on coronaliy repositioned flap procedure with and without the use of ethylenediaminoteraacetic acid (edta. 24%, ph=7) in the treatmen...

PURPOSE The purpose of this paper is to investigate how much correction is obtained per millimeter of medial rectus (MR) resection for recurrent exotropia after bilateral lateral rectus (BLR) recession, and to determine the difference in the effects between unilateral and bilateral resection, and the influence of previous lateral rectus (LR) recession on the effects of MR resection. METHODS A...

STATEMENT OF THE PROBLEM Gingival recession has been considered as the most challenging issue in the field of periodontal plastic surgery. PURPOSE The purpose of this study was to evaluate the clinical efficacy of root coverage procedures by using partial thickness double pedicle graft and compare it with full thickness double pedicle graft. MATERIALS AND METHOD Eight patients, aged 15 to 5...
