Full textAbstract:
Prior to the recent global crisis a consensus was emerging that post-Fordism had ushered in a new sexual contract, one characterized not by exclusion and containment, but by the prospecting for potential, a prospecting that located women’s labor not as a reserve for capital but as a site of vitality and possibility. The global financial crisis and ongoing recession, however, have been positioned as undoing these radical transformations in women’s labor by threatening a return of the social formations characteristic of Fordism. Yet in this essay I suggest that to understand the ongoing recession as producing such a return is to thoroughly misapprehend value production in post-Fordism and, in particular, to bracket the process of the folding of the economy into society. To illustrate this process, I focus on unemployment, specifically the eventful productiveness of unemployment in recessionary post-Fordism. Confronting this eventful productiveness necessitates not only a recognition of a material reworking of unemployment in post-Fordism, but also undoes the idea that the ongoing recession is linked to a return to the social formations of Fordism. This essay therefore posits that unemployment is a crucial site for the theorization of post-Fordist labor, including the ongoing, radical reworking of the potentialities of female labor.

ABSTRACT
Background: Gingival recession (GR) can result in hypersensitivity, esthetic concern to the patient, and chances for root caries. The purpose of this randomized clinical study was to evaluate the effect of guided tissue regeneration (GTR) procedure using a bioabsorbable collagen membrane in comparison to autogenous Subepithelial connective tissue graft (SCTG) for root coverage in Miller’s class I and II gingival recession defects.
Materials and methods: In this split mouth study, 10 patients with 20 contralateral Miller’s class I or II recession defects were randomly treated with coronally advanced flap using either Subepithelial connective tissue graft (control group) or resorbable collagen membrane (experimental group). The clinical evaluations were done using plaque index, gingival index, height of gingival recession, probing sulcus depth and clinical attachment level at baseline, 3 and 6 months post- operatively.
Results: Data analysis was done using descriptive statistics and student’s t test was used for comparisons. P value <0.01 was considered to be significant. Both the groups showed complete resolution of the defects at 6 months post operatively. Inter group comparison between both the groups at 6 months showed no statistically significant differences in any of the clinical parameters.
Conclusion: Predictable outcome were observed in both the groups and indicated that collagen based guided tissue regeneration membrane i.e. ProGide can be safely used.

På sin vis har forskningen i Keynes’ forfatterskab vist sig at være særdeles sejlivet. Således dannede dette baggrunden for den keynesianske æra og gav nogen inspiration til den ny-keynesianske teoridannelse. Der forskes også stadigvæk aktivt i forfatterskabet især inden for post keynesianske kredse. Om end i perioder under pres forsvandt keynesianismen dog aldrig helt, og efter The Great Recession og Covid-19-pandemien er keynesianismen så aktivt tilbage i makroteorien? Og hvad med den post keynesianske tænkning? Vinder denne også øget anerkendelse? Om især disse aspekter handler nærværende artikel.

Full textAbstract:
Among the periodontal infections, gingival recession is a separate clinical entity which demands a permanent solution plan. Treatment therapies are based on either elimination (as in case of Miller’s class I/II recession) or increasing the width of keratinized gingiva for prevention of further progression (as in case of Miller’s class III/IV recession). From the centuries, graft surgeries like free gingival graft, lateral pedicle and Coronally advanced flaps have been successful in the treatment of gingival recession. As every technique has its own merits and demerits, clinicians have tried to stress upon addition of certain adjuncts or biomaterials to ensure rapid healing and less post-operative discomfort. Platelet concentrates are an excellent biomaterials for increasing width of attached gingiva and enhancing wound healing. They are cost effective, do not require donor tissue for harvesting and contain variety of growth factors for initiating regeneration. In this paper, Platelet-rich fibrin a 2nd generation concentrates has been used as an adjunct to Coronally advanced flap with a purpose of increasing width of keratinized gingiva, obtaining complete root coverage and achieving gingival harmony.

Has government spending raised income and employment since 2008? I use new data on state pension returns during the Great Recession to recover exogenous changes in spending. Instrumenting with these return shocks, I estimate that each dollar of windfall-financed spending raised local incomes by $1.43 and every additional $22,011 of spending created one contemporaneous job. These estimates are similar to those found in Shoag (2010) despite the non-overlapping datasets. Unlike Shoag (2010), however, the bulk of the employment increase post-2008 stems from decreases in unemployment rather than increased labor force participation.

Background: The present study has been designed to compare the effect of root surface biomodification with EDTA for the treatment of buccal gingival recession with free gingival graft.
Materials and methods: This randomized controlled parallel clinical trial, 34 patients of 40 existing tooth Miller Class I and Class II gingival recession were treated with free gingival graft (FGG). Forty teeth with recession were assigned randomly to receive the free gingival graft with or without the application of an EDTA gel. Pre-treatment (Day 0) and post-treatment 3. and 6. months gingival recession height(GRH), gingival recession width(GRW), probing depth (PD), clinical attachment level(CAL) and width of keratinized tissue WKT were measured.
Results: In FGG+EDTA group statistically significant changes from baseline were found GRH decreased from 4.7±1.5 mm to 1.3±1.2 and WKT increased from 0.9 ± 0.9 mm to 5.5±1.8 mm. Also in FGG group, GRH decreased from 4.6±1.3 mm to 1.3±1.2 mm and WKT increased from 0.9 ± 0.7 mm to 5.4±1.5 mm. For FGG and FGG+EDTA, the average root coverage 74.14% and 69.26% was found.
Conclusion: In the light of these data obtained with the root surface biomodification agent EDTA have no beneficial effect for root coverage. In the light of these data obtained with the root surface biomodification agent EDTA have no beneficial effect for root coverage.

Full textAbstract:
This paper charts emerging scholarship on what I conceptualise as 'compensatory cultures'; cultures that are, in essence, compensatory responses to crisis, but are presented and received as desirable, even preferable ways of organising life. Since the 2008 crash, precarity has become a new normal and a dominant structure-of-feeling in the global north. I argue that compensatory cultures alleviate precarity's affective impacts, enabling 'business as usual', yet do so in ways that perpetuate that precarity and the conditions that reproduce it. I survey literature on compensatory urbanisms, compensatory labour and compensatory consumption; demonstrating the compensatory as a pervasive mechanism operating across various cultural settings in the post-recession, austerity context. The work explored reveals compensatory cultures as central in remaking places, structuring social relations and producing meaning in crisis times.

This commentary responds to Boyer, Dermott, James and MacLeavy’s examination of the post-recession regendering of care in the UK. My response is informed by my geographical position in Australia. I first discuss what I see as the key contributions of the paper: the socio-spatial dynamics of male care giving, and the significance of economic structures, employment conditions and workplace gender norms for the potential regendering of care. I then offer two sets of suggestions for further thinking and research on the geography of male care giving: nuanced attention to the diverse spaces and subjectivities of male care giving.

Longitudinal, individual-specific data from the Multi-Ethnic Study of Atherosclerosis (MESA) provide support for the hypothesis that the 2008 to 2010 Great Recession (GR) negatively impacted the health of US adults. Results further advance understanding of the relationship by (i) illuminating hypothesized greater negative impacts in population subgroups exposed to more severe impacts of the GR and (ii) explicitly controlling for confounding by individual differences in age-related changes in health over time. Analyses overcome limitations of prior work by (i) employing individual-level data that avoid concerns about ecological fallacy associated with prior reliance on group-level data, (ii) using four waves of data before the GR to estimate and control for underlying individual-level age-related trends, (iii) focusing on objective, temporally appropriate health outcomes rather than mortality, and (iv) leveraging a diverse cohort to investigate subgroup differences in the GR’s impact. Innovative individual fixed-effects modeling controlling for individual-level age-related trajectories yielded substantively important insights: (i) significant elevations post-GR for blood pressure and fasting glucose, especially among those on medication pre-GR, and (ii) reductions in prevalence and intensity of medication use post-GR. Important differences in the effects of the GR are seen across subgroups, with larger effects among younger adults (who are likely still in the labor force) and older homeowners (whose declining home wealth likely reduced financial security, with less scope for recouping losses during their lifetime); least affected were older adults without a college degree (whose greater reliance on Medicare and Social Security likely provided more protection from the recession).

The labor market in the Great Recession and its aftermath is characterized by great difficulty in escaping unemployment. I present two empirical analyses of a particular explanation for that difficulty, that the housing market crisis has prevented the unemployed from selling their homes and moving to take new jobs. First, I examine post-job-loss mobility rates by home ownership status using data from the Displaced Workers Survey. Second, I examine mobility rates for unemployed homeowners and renters from the month-to-month CPS match. Neither analysis provides any support for the idea that the housing market crisis has reduced mobility of the unemployed.

Full textAbstract:
Background: Gingival recession is defined as a mucogingival deformity that includes the apical displacement of the marginal soft tissues below the cemento-enamel junction, loss of attached gingiva, and exposure of root surfaces. The present study aims to compare root coverage outcomes between autogenous Connective Tissue Graft (CTG) and decellularized human dermis (OrACELL™) in areas of facial gingival recession. Methods: Twenty-four non-smoking, healthy patients, with 2mm or greater facial gingival recession at a minimum of one site that is classified as Miller Class I, II, or III recession defects were included. Patients were randomly assigned to either control (CTG) or OrACELL™ (test) groups, which were treated with identical surgical techniques. All root coverage clinical parameters were evaluated at baseline, 3, and 6-months. Results: Eleven patients received CTG while 13 patients received OrACELL™; 23 of the 24 total patients had Miller Class III defects. Baseline mean Vertical Recession (VR) (CTG = 3.27±0.68 mm, OrACELL™ = 3.50±0.89 mm) and Clinical Attachment Level (CAL) (CTG = 4.86±0.74 mm, OrACELL™ = 4.73±0.90 mm) showed no significant difference between groups. At 6 months, mean VR (CTG = 0.59±0.70 mm, OrACELL™ = 1.19±1.07 mm) significantly decreased in both groups, whereas CAL (CTG = 1.90±1.00 mm, OrACELL™ = 2.42±1.17 mm) significantly increased in both groups. Differences between group means were not statistically significant. Conclusion: VR and CAL improved significantly in both the CTG and OrACELL™ groups from baseline to 6 months post-operatively, with no significant differences between groups regarding VR or CAL over the course of the study. In Miller Class III recession defects, OrACELL™ provided a viable alternative to CTG with similar results.

Full textAbstract:
Labour markets in post-transition countries have undergone radical changes, with a shift away from full employment and strong legal protection for employees, though the extent of these changes has differed between countries. I show that the loosening of employment protection went in parallel with growing income inequality and widening poverty levels, which led to a rise in household debt. This enabled additional consumption in the short term, but later deepened recession by hampering consumption. Following the financial crisis, the tendencies to make labour markets more flexible were confirmed and strengthened. This was facilitated by the weakness of trade unions, conditioned by structural changes brought about by transition.

The purpose of this retrospective study was to associate the amount of keratinized gingiva present in adolescents prior to orthodontic treatment to the development of gingival recessions after the end of treatment. The sample consisted of the intra-oral photographs and orthodontic study models from 209 Caucasian patients with a mean age of 11.20 ± 1.83 years on their initial records and 14.7 ± 1.8 years on their final records. Patients were either Angle Class I or II and were submitted to non-extraction orthodontic treatment. Gingival recession was evaluated by visual inspection of the lower incisors and canines as seen in the initial and final study models and intra-oral photographs. The amount of recession was quantified using a digital caliper and the observed post-treatment gingival margin alterations were classified as unaltered, coronal migration of the gingival margin or apical migration of the gingival margin. The width of the keratinized gingiva was measured from the mucogingival line to the gingival margin on the pre-treatment photographs. The teeth that developed gingival recession and those that did not have their gingival margin position changed did not differ in relation to the initial amount of keratinized gingiva (3.00 ± 0.61 and 3.5 ± 0.86 mm, respectively). Paradoxically, teeth that presented a coronal migration of the gingival margin had a smaller initial amount of keratinized gingiva (2.26 ± 0.31 mm). The mean amount of initial keratinized gingiva did not predispose lower incisors and canines to gingival recession.

Over the past decade, Venezuela has entered into a deep recession, which has resulted in millions migrating abroad. In February of 2019, the United States and its allies recognized the interim government of Juan Guaidó, creating a standoff with the Chavista government of Nicolás Maduro. This article conducts a nuanced analysis of the situation in Venezuela across multiple levels as it problematizes our ontological understanding of individuals, states, and international system. Through a post-structuralist approach to security, I argue that individuals have been portrayed in contradictory humanitarian discourses as a means of advancing particular political interests. Furthermore, I critically analyze the role of space, time, and multilateralism, and their subsequent effects for 21stcentury global order.

Abstract Aims “Gingival recession is a condition reported to occur due to abnormal periodontal anatomy, poor hygiene, excessive occlusal forces, toothbrush abrasion, and even iatrogenic or factitious causes. Though various surgical techniques are available to treat this problem, the most common is the palatal soft tissue autograft. Recently, an acellular dermal matrix allograft (ADMA) has been available as a substitute for the palatal tissue harvest. The aim of this study is to compare the ADMA with the conventional subepithelial connective tissue graft (SCTG) in the treatment of gingival recession.” Methods and Materials Fourteen patients with 20 gingival recessions of Miller's grade I and II were selected and randomized in two groups of control (SCTG) and test (ADMA). In each group ten recession defects were treated. The following parameters were measured at baseline and then at six months post surgery: recession height (RH), recession width (RW), probing depth (PD), attached gingiva (AG), keratinized gingiva (KG), and clinical attachment level (CAL). All parameters were analyzed using the two-sample t-test. Data analysis was performed using SPSS (version 11) software. Results The following mean changes (mm) occurred in SCTG and ADMA, respectively: 2.60±0.97 and 2.90±0.81 decrease in RH; 1.70±1.01 and 1.65±0.67 decrease in RW; 2.50±0.97 and 2.95±0.69 increase in KG; 2.25±0.92 and 2.65±0.85 increase in AG; 2.60±1.08 and 2.75±0.92 decrease in CAL; and finally 0.05±0.50 and 0.10±0.46 decrease in PD for the SCTG and ADMA groups, respectively. The percentage of root coverage for the two groups was 70.12%±22.81% and 72.08%±14.12%, respectively. The changes from baseline to the six-month visit were significant for both groups in terms of all parameters but PD. However, the differences in mean changes were not significant between the two groups in any of the parameters. Conclusion These findings imply the ADMA and SCTG techniques could produce the same results when used for the successful treatment of gingival recessions. In addition the ADMA could be used as an adequate alternative treatment modality for conventional techniques. Citation Rahmani ME, Lades MAR.

Many have argued that a deviation from good economic policy has been a cause of the poor U.S. economic performance of the past decade and that policy reforms are needed to restore strong growth. Yet others argue that the recent stagnation is secular or that the possibility of a rapid recovery is long gone without more fiscal stimulus. Here I show that unusual economic conditions leave plenty of room for a reform-induced rebound. Taking demographics and the growth of capital services into account, labor force participation and productivity growth are unusually low. Hence, policy reforms could generate a post-recession-like acceleration as well as sustained growth and stability.

Abstract: The aim of this randomized controlled clinical study was to compare the extended flap technique (EFT) with the coronally advanced flap technique (CAF) using a porcine collagen matrix (PCM) for root coverage. Twenty patients with two bilateral gingival recessions, Miller class I or II on non-molar teeth were treated with CAF+PCM (control group) or EFT+PCM (test group). Clinical measurements of probing pocket depth (PPD), clinical attachment level (CAL), recession height (RH), keratinized tissue height (KTH), keratinized mucosa thickness (KMT) were determined at baseline, 3 and 6 months post-surgery. At 6 months, the mean root coverage for test group was 81.89%, and for control group it was 62.80% (p<0.01). The change of recession depth from baseline was statistically significant between test and control groups, with an mean of 2.21 mm gained at the control sites and 2.84 mm gained at the test sites (p=0.02). There were no statistically significant differences for KTH, PPD or CAL comparing the two therapies. The extended flap technique presented better root coverage than the coronally advanced flap technique when PCM was used.

Objective: This study aims to evaluate periodontal clinical conditions after treatment for gingival recession (GR) using subepithelial connective tissue graft (SCTG) and acellular dermal matrix (ADM).Methods: Ten patients with Miller’s Class I and II recessions that had been treated with SCTG or ADM at the Periodontics Outpatient Department at Universitas Indonesia were selected for this study. The pre-operative data for GR, clinical attachment levels (CAL), and attached gingiva (AG) were retrieved from the patients’ medical records. The patients were recalled and the post-operative data were recorded.Results: The application of SCTG and ADM yields significant changes to GR, CAL, and AG levels. A comparison of two groups at the post-operative assessment stage showed no statistically significant differences, in terms of GR, CAL, and AG.Conclusion: SCTG and ADM yield similar outcomes in the treatment of GR. As such, ADM may be suggested as an alternative to SCTG for root coverage.

Full textAbstract:
Oil dependent economies of GCC countries had passed through various cycles of boom and trough of oil price. In the aftermath of the economic recession of 2008 and oil price, the GCC countries have been pursuing plans for diversifying to non-oil revenues. The oil of 2014-16 raised the issue of stock market cointegration to oil price movement in the background of non-oil diversification.This research study analyzes long term cointegration of oil price and GCC stock indices, and also cointegration among the GCC stock indices per se in an attempt to investigate if there is any early sign of disintegration of GCC stock markets from oil price cyclicality. The study period is linked to cyclicality of oil price: the first period comprising of Jan 2006- Dec. 2011 that covers oil price cycle during economic recession of 2008, and the second period comprising of Jan 2012 –September 2016 which covers the post-economic recession oil price cycle. The null hypotheses is that oil price and stock market indices are co-integrated.Based on Johansen Cointegration test on Box Cox transformed data of oil price and seven stock market indices of GCC countries, it is found that oil price and GCC stock markets are co-integrated. Analysis using Augmented Dickey- Fuller test and Phillips –Perron test shows that data series are all I (1). This study establishes that efforts to reduce oil dependency in GCC countries is yet to result in decoupling of financial markets from oil price cyclicality. This study also establishes that GCC stock markets per se are co-integrated but factors of cointegration beyond oil price are not explored.

Full textAbstract:
Existing methods for estimating nonlinear dynamic models are either highly computationally costly or rely on local approximations which often fail adequately to capture the nonlinear features of interest. I develop a new method, the discretization filter, for approximating the likelihood of nonlinear, non‐Gaussian state space models. I establish that the associated maximum likelihood estimator is strongly consistent, asymptotically normal, and asymptotically efficient. Through simulations, I show that the discretization filter is orders of magnitude faster than alternative nonlinear techniques for the same level of approximation error in low‐dimensional settings and I provide practical guidelines for applied researchers. It is my hope that the method's simplicity will make the quantitative study of nonlinear models easier for and more accessible to applied researchers. I apply my approach to estimate a New Keynesian model with a zero lower bound on the nominal interest rate. After accounting for the zero lower bound, I find that the slope of the Phillips Curve is 0.076, which is less than 1/3 of typical estimates from linearized models. This suggests a strong decoupling of inflation from the output gap and larger real effects of unanticipated changes in interest rates in post Great Recession.

Full textAbstract:
Introduction. Fibrin, fibronectin, platelet derived growth factor, and transforming growth factors from platelet concetrate are crucial for tissue reparation and regeneration. Objective. This study was designed to evaluate clinical effectiveness of activated platelet-rich fibrin (PRF) membrane in treatment of gingival recession. Methods. 19 gingival recessions Miller class I or II were treated with a coronally advanced flap and the PRF membrane (PRF group). Following the elevation of the flap, bone and root surfaces were covered with the PRF membrane. After suturing, the PRF membrane was covered with a coronally advanced flap. In the same patients, 19 other gingival recessions were treated with CTG in combination with the coronally advanced flap (the CTG group). Clinical recordings were made of vertical recession depth (VRD), probing depth (PD), clinical attachment level (CAL) and keratinized tissue width (KTW) before and 12 months after mucogingival surgical treatment. Clinical evaluation of healing events was estimated with recordings of the healing index (HI). Recordings of HI were performed in the 1st, 2nd and 3rd week post-surgically. Results. Mean root coverage was significant in both groups (the PRF group 79.94% and the CTG group 88.56% %; p<0.01). The difference between the two tested groups was not statistically significant. Results of the keratinized tissue width showed significant increase (p<0.05) 12 months after the surgery in both, the PRF and CTG groups. Results of KTW showed statistical significance of recorded differences obtained in the two evaluated groups (p<0.05). There was no statistical significance in reduction of PD and CAL recorded in the PRF and CTG groups. The values of HI recorded in the 1st and 2nd week postoperatively were significantly enhanced in the PRF group (p<0.05). Conclusion. Results of this study confirm both procedures as effective with equivalence of clinical results in solving gingival recession problems. The utilization of the PRF resulted in a decreased postoperative discomfort and advanced tissue healing.

Full textAbstract:
This article explores the concepts of dignity at work and worker voice in the public workplace during a period of surging neoliberal austerity intended to reduce taxes, government regulations, and public services. I ask how the changing landscape of public employment in the neoliberal era has created new and exacerbated existing threats to dignity at work and how workers have responded to such threats. The question is answered by exploring how and why an unlikely group of workers in Smalltown chose to use their collective voice on the job to organize a union. Using ethnographic methods, I am able to look at the strategies of public workers coping with a changing work environment in real time. The case of Smalltown offers a window into the interplay of the global and the local by examining how macro-level neoliberal forces can shape workers’ micro-level responses to attacks on their dignity at work. The findings reveal how neoliberal attacks on public workers in particular settings can trigger collective responses that confront not merely austerity but other threats to dignity as well. This study informs our understanding of dignity at work and worker resistance in the post-Great Recession economy.

Full textAbstract:
In this article I consider how registers of weather media carry/convey cultural information, specifically how texts about extreme weather articulate with investment in a supposed post-recession restored normality marked by the Irish government's commitment to deregulated transnational capitalism. I maintain that, in a process of cross-cultural remediation, sensationalist codes of US weather media that discursively manage awareness of systemic climate problems are just starting to infiltrate the Irish broadcasting environment. In early December 2015 RTÉ’s Teresa Mannion covered a strong gale, Storm Desmond, amidst inclement conditions in Salthill, Co Galway. Modelling the kind of ‘body at risk’ coverage consummately performed by US Weather Channel personnel, Mannion could barely speak over the lashing rain and strong winds in a dramatic broadcast that quickly became a viral video. This article analyses the fascination with Mannion's piece and its memetic, and attends to the nature of the pleasure taken in her on-camera discomfiture and the breach of gendered territory committed by Mannion at a time when national popular culture in Ireland is under increased obligation to identify and explain climate change-related extreme weather.

Full textAbstract:
This article concerns itself with financial traders in Spain who have been diagnosed with gambling disorder. It analyzes what I call the clinical economy of speculation, in which the category of problem gambler is repurposed to draw new lines around proper financial trading. In exploring the expansion of post–financial crisis regulatory mechanisms for credit and debt, as well as widening inequalities across the field of investment, I depict how both traders and clinicians become invested in medicalizing trading as gambling disorder. My theorizing interrogates whether and why common speculative practices are seen as sick and unsafe when everyday people, instead of banks and other financial institutions, perform them. I argue that the pathologized trader is an attempt to regulate, at the individual level, the increasing use of borrowed capital to make financial profits. The commodification of debt, however, is not a gender-neutral development. Female traders pay a greater price for venturing into the heights of finance. This focus on gender brings into view the redefinition of credit and debt within the domain of trading, and shows the role of debt-fueled financial speculation in the expansion of financial markets. These ethnographic findings are particularly relevant in a country like Spain, where the Great Recession has bred more new millionaires than ever before, even as the smaller fish of the economy are being medicalized and sometimes even incarcerated.

Orthognathic surgery is a branch of maxillo-facial surgery increasingly in demand, which deals with the correction of skeletal deformities. The aim of the present study is to identify the most common post-operative complications following orthognathic bimaxillary surgery performed by means of Piezosurgery®. Furthermore, through an examination of the available scientific literature, we wanted to establish whether the frequency of postoperative complications were consistent with those already reported. A retrospective study on 58 patients who underwent orthognathic surgery with a bilateral sagittal osteotomy (BSSO) of the mandibular bone branch, maxillary surgery with Le Fort I mono-segmented or multi-segmented approach, and genioplasty technique using Piezosurgery®. The complications taken into consideration were disorders of the temporomandibular joint (TMJ), paraesthesia and hypoesthesia, asymmetries, nose enlargement, nasal septum deviation, nasal obstruction, dental discolorations, pulpal necrosis, occlusion and masticatory efficiency, gingival recession, periodontal problems, dysgeusia, nausea and vomiting, weeping alterations, hearing problems, delayed healing, superinfection, removal of synthesis means, reoperation, cicatricial outcome, and bilateral pneumothorax. It has been highlighted that a number and type of postoperative complications matched those reported by the most recent literature reviews. Temporomandibular disorders and paraesthesia were the most common ones. The only complication rate that differed from the literature was nerve damage, which was significantly lower. Post-surgical complications depend on the used surgical techniques, clinical work, and treatment methods. The use of piezoelectric devices in orthognathic surgery operations provides an innovative, safe, and effective technique compared to traditional methods.

Full textAbstract:
Hot corrosion affects the components of diesel engines and gas turbines working at high temperatures, in the presence of low-melting salts and oxides, such as sodium sulfate and vanadium oxide. Thermal-sprayed coatings of nickel–chromium-based alloys reinforced with ceramic phases, can improve the hot corrosion and erosion resistance of exposed metals, and a sealing thermal, post-treatment can prove effective in reducing the permeability of aggressive species. In this study, the effect of purposely-optimized high-power diode laser reprocessing on the microstructure and type II hot corrosion resistance of cermet coatings of various compositions was investigated. Three different coatings were produced by high velocity oxy-fuel and was tested in the presence of a mixture of Na2SO4 and V2O5 at 700 °C, for up to 200 h: (i) Cr3C2–25% NiCr, (ii) Cr3C2–25% CoNiCrAlY, and (iii) mullite nano–silica–60% NiCr. Results evidenced that laser sealing was not effective in modifying the mechanism, on the basis of the hot corrosion degradation but could provide a substantial increase of the surface hardness and a significant decrease of the overall coating material consumption rate (coating recession), induced by the high temperature corrosive attack.

In planning orthodontic cases that include extractions as an alternative to solve the problem of negative space discrepancy, the critical decision is to determine which teeth will be extracted. Several aspects must be considered, such as periodontal health, orthodontic mechanics, functional and esthetic alterations, and treatment stability. Despite controversies, extraction of teeth to solve dental crowding is a therapy that has been used for decades. Premolar extractions are the most common, but there are situations in which atypical extractions facilitate mechanics, preserve periodontal health and favor maintenance of the facial profile, which tends to unfavorably change due to facial changes with age. The extraction of a lower incisor, in selected cases, is an effective approach, and literature describes greater post-treatment stability when compared with premolar extractions. This article reports the clinical case of a patient with Angle Class I malocclusion and upper and lower anterior crowding, a balanced face and harmonious facial profile. The presence of gingival and bone recession limited large orthodontic movements. The molars and premolars were well occluded, and the discrepancy was mainly concentrated in the anterior region of the lower dental arch. The extraction of a lower incisor in the most ectopic position and with compromised periodontium, associated with interproximal stripping in the upper and lower arches, was the alternative of choice for this treatment, which restored function, providing improved periodontal health, maintained facial esthetics and allowed finishing with a stable and balanced occlusion. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements for obtaining the BBO Diplomate title.

Full textAbstract:
This article looks at the issue — largely neglected in the transition literature — of the relative weights of the privatized sector and the generic private sector (of de novo private firms) in the emerging private sector of post-communist economies in transition. The present writer posits that the relative weight of each in the aggregate share of a private sector (generally expanding over time as transition progresses) strongly influences economic performance, both during correctional recession and during recovery and expansion period. Another, interrelated issue considered here is the interaction between the evolving institutional framework and the expansion of the generic private sector, that is the most dynamic one in the transition economy. It is true that the interaction between institutions and performance has been a staple of a very large number of books, articles, and papers. However, this article concentrates on one component of a private sector only, that is the generic private sector. But at the same time it looks beyond the ‘Holy Trinity’ of transition (stabilization, liberalization, and privatization) towards a wider institutional framework of political liberty, law and order. The foregoing wider framework, and the emerging general trust, matters as much — if not more — for the present writer as the standard transition program. It is the relative dynamics of both components of the private sector, affected by both standard transition programs and the above-mentioned wider institutional framework, that is of primary importance for the economic performance in post-communist transition. In the last part of the article I will try also to answer, tentatively, the question under which circumstances the wider institutional framework may emerge in the transition process.

Full textAbstract:
Abstract The great recession of 2007–2009 has led to historically high unemployment rates, and almost half of the unemployed population was long-term unemployed in 2010. Both discriminations against the long-term unemployed and ageism hinders older unemployed workers reentering the workforce, and they risk severe mental health deterioration. However, traditional job training programs are shown to be ineffective in protecting their participants’ mental health. Hence, adopting Jahoda’s Latent Deprivation Theory, the author worked with a non-profit in the Greater Boston area on developing an innovative intervention targeting older unemployed older workers’ mental health and income generation outcomes. The pilot intervention (lasting three months) created a quasi-office environment where participants can have a time structure, engage with peers, work on projects, and receive training. The current study evaluates the effect of this pilot program on multiple mental health outcomes. Pre-and-post comparisons were conducted using quantitative analysis (N=13). Participants’ depressive symptoms dropped significantly, and they reported having a better time structure of the day as well as higher scores in extraversion in terms of personality change. Qualitative analyses were conducted to analyze the pre-and-post interviews. Participants reported overwhelming approval of the intervention in helping them better cope with unemployment and being productive in seeking jobs or generating incomes. One example of quotes is “…compared to three months ago, I’m in a very different place. Before the Collaboratory, I had become extremely depressed and withdrawn…The Collaboratory has helped make a massive difference in my sense of well being right now.”

Full textAbstract:
Fish kills following austral summer flood events (November–March) occur episodically in estuarine channels in Australia. We examined the climatic conditions associated with the historic record of such events in a subtropical region in eastern Australia to determine the effect of antecedent weather conditions on the probability of post-flood fish-kill events. Records, including regional county council logs, newspapers and New South Wales Fisheries annual reports, were analysed for reports of floods and fish kills following these events. Daily rainfall patterns preceding floods with fish-kill events tended to be drier than rainfall patterns preceding floods when a fish kill did not occur. Based on these observations, it is proposed that estuarine hypoxia resulting in a fish kill is increased by prolonged dry periods followed by rapid and intensive rainfall preceding the flood peak. This is most likely due to (i) accumulation of organic material on the floodplain due to vegetation stress and reduced decomposition processes in drier conditions; (ii) upstream migration of the salt wedge, allowing some estuarine fish species to maintain an optimum environment, followed by flooding with (iii) rapid consumption of dissolved oxygen during decomposition of accumulated organic material sourced from senescent vegetation; and (iv) fish becoming trapped upstream in discharging hypoxic floodwater during the flood recession phase.

The article examines the clinical and roentgenological changes in the periodontal tissues of laboratory animals when mesenchymal stem cells (MSC) are used.The aim of the study is to create a model of experimental periodontitis and identify the characteristics of clinical and radiological changes in periodontal tissues when applying a biomedical cell product based on allogeneic mesenchymal adipose stem cells (AT MSCs).During the examination of the clinical and radiological changes in the periodontal tissues ofexperimental animals with formed bone defects filled with AT MSCs, it was found that the mucous membrane regeneration time in the surgical area was comparable in all main groups of animals. Postoperative gum recession was observed in the control group animals. The significant differences between the clinical pictures in groups I–IV during all observation periods after surgery were not revealed. However, the restoration process signs in the post-resection area found during the roentgenological examination in the groups using osteoinduced MSCs, as well as a mixture of MSC cultures and osteo-induced MSCs, were most pronounced, which is confirmed by the bone mineral density.The experimental periodontitis model, which could be used for assessing the bone tissue restoration processes of a labioratory animal, was developed. Thus, the use of collagen membranes with a suspension of allogeneic osteo-induced AT MSCs cultures, as well as membranes with a suspension of a mixture of allogeneic and allogeneic osteo-induced AT MSCs in the ratio of 1:1 allows achieving higher bone tissue recovery rates.

Full textAbstract:
AbstractStruggles over social reproduction intensified and took on new forms in Japan during the interwar period, as the state found it increasingly difficult to secure the foundations for the continued accumulation of capital. Landlord-tenant disputes that erupted nationwide in the midst of Japan's post-World War I agricultural recession was one concrete manifestation of these struggles. While the significance of tenant disputes has been analyzed in great detail by scholars, there has been a surprising lack of historical scholarship on the role that female tenant farmers played within them. This absence is a manifestation of two tendencies: First, gendered assumptions surrounding the figure of the tenant farmer have led scholars of agrarian social movements to work from a relatively limited understanding of what constitutes struggle and by extension, who its protagonists have been. Second, the conflation of waged work as productive work and by extension, non-waged work as unproductive has unwittingly relegated many forms of struggle that working women participated in to the realm of the pre-political. This paper contends that far from being mere supporters – the wife corps – of what was ultimately a male-driven movement, female participants in tenant disputes produced their own powerful critiques of the way that the Japanese state and capital undervalued their lives and labor. As such, they should be understood as one link in a rich history of proletarian feminist struggle both within and outside of the Japanese empire.

Full textAbstract:
When the 30-year old English-born, Auckland-trained Robert Mackay Fripp (1858-1917) and his New Zealand bride left the port of Auckland in the late summer of 1888, they were headed for the bustling construction environment of post-fire Vancouver. Leaving his practice with C Paul, and his architectural design tutorship at the Auckland Society of the Arts, Fripp's was an astute career move. In the not quite eight years Fripp was based in Vancouver, he built and published almost 50 projects in British Columbia before he escaped the fast-approaching Vancouver recession and returned to Auckland in 1896. Attempting to put himself forward for more prestigious commissions in the Lower Mainland and Vancouver Island (which regularly went to Samuel Maclure), Fripp developed a national profile as an Arts and Crafts aesthete and designer with considerable international experience by publishing his drawings and reporting on the "West Coast scene" in the Toronto-based Canadian Architect and Builder (CAB). Among the local-interest articles there, which he consistently turned into a crabby proselytising for the Arts and Crafts, Fripp also placed both appreciative and critical articles and notes on Māori architecture and domestic design, and timber and construction in Auckland, and, even more surprisingly, he continued to do so throughout the 1890s, that is, long after he returned to New Zealand and set-up in partnership with GS Goldsboro' in Auckland. Meanwhile in the 33 months Fripp was back in Auckland from 1896 he realised a number of substantive and significant Auckland houses in Parnell, Grafton and Mount Eden. In these works I will show that he can be seen to have brought current "progressive" ideas from the West Coast about strongly-shaped shingled and half-timbered houses simply detailed with heavy timber to stand within the strong ocean coastal conditions. Fripp left for Victoria in 1899 and after some disappointing (losing the competition for Government House to Francis Rattenbury) months, during which he posted a scathing report in CAB about house design in Auckland, he moved to Los Angeles renting office space immediately adjacent to the Greene brothers executing and publishing a series of large (as yet undiscovered) houses in and around Santa Monica and Pasadena throughout 1900-5.

The large capital concentrated in the Central Union of the Polish Industry, Mining, Trade and Finance, called “Lewiatan”, as well as the Upper Silesian industrialists, whose interests were represented by the Upper Silesian Association of Mining and Metallurgical Industrialists both defended themselves against the negative effects of the crisis. They sent petitions to the government in which they demanded tax breaks, exemption from customs duties, subsidies, reduction of social burdens, etc., otherwise threatening with mass dismissals of employees. At the same time, they were looking for the easier survival of the recession in the accelerated process of monopolizing of the industry. Research method – The source analysis method, comparative method and simple description method were used. Originality /value – The article cites statements and publications of entrepreneurs and their spokespersons, as well as reports on industrialists’ demands for the government. The text uses both pre-war and post-war economic historians studies as well as archival sources, especially regarding the industrial spheres of Upper Silesia.

Full textAbstract:
Ireland, the UK and the USA are heterogeneous examples of liberal worlds of welfare capitalism yet all three countries were deeply implicated in the 2008 global financial crisis. Examining these three countries together provides the opportunity to further develop an international comparative political economy of instability in the context of the globalised and financialised dimensions of Anglo-liberal capitalism and disciplinary governance. Our analysis is guided by the concept of disciplinary neoliberalism (Gill, 1995) through which we explore: (i) the dynamics that have shaped the impacts of and responses to the Great Recession; (ii) the ways in which state-market relations, shaped by differentiated accommodations to market imperative or market discipline, have been used as disciplinary tools and how these have interacted with existing social divisions and iii) the implications for shaping conditions for resistance. We suggest that the neoliberal pathways of each country, whilst not uniform, mark a ‘step-change’ and acceleration in the operation of disciplinary neoliberalism, and is particularly evident in what we identify as the coercive commodification of social policy.

Disasters and pandemics such as COVID-19 will change the world in many ways and the road to redemption from the ongoing economic distress may require a novel approach. This paper proposes a path towards economic recovery that keeps sustainability at the forefront. A computable general equilibrium model is used to simulate different green tax reform (GTR) policies for triple dividend (TD), consisting of lower emissions, higher GDP and higher employment. The GTR design consists of an energy tax coupled with one of three tax revenue recycle methods: (i) reduction of payroll tax, (ii) reduction of goods and services tax (GST) and (iii) a mixed-recycling approach. The paper also presents the impact of higher productivity on the tax reform simulations, which is a possible positive externality of lower emissions. The study is based on the Australian economy and the salient findings are twofold: (i) productivity gain in the GTR context improves the GDP and employment outcomes in all three different simulation scenarios and (ii) GST reduction has the highest TD potential, followed by reduction of payroll tax.

SUMMARYMore than 10 Sub1 rice varieties carrying the submergence-tolerance gene have been released for flood-prone environments in tropical Asia. Improved management practices have been shown to enhance yields of these varieties. The objective of this study was to dissect the growth response of IR64-Sub1 to integrated crop management in a flash flood at the late vegetative stage. Field experiments were conducted at the International Rice Research Institute, Philippines in the dry and wet seasons of 2013. Complete submergence was imposed for 14 days starting at 37 days after transplanting. Integrated management practice (IMP) consisting of: (i) application of fertilizer (compared with no fertilizer use in conventional practice), (ii) use of lower seeding rate (400 vs. 800 kg ha−1) in the nursery bed, (iii) use of slightly older seedling for transplanting (30 vs. 18 day-old), and (iv) higher planting density (33.3 vs. 25.0 hills m−2) gave yields higher by 8–87% compared with the conventional practice (1.3–2.4 t ha−1) in both seasons. This was attributable to higher shoot biomass after water recession, more tillers m−2, greater leaf area expansion and shoot biomass accumulation during the recovery period, and higher filled-grain percentage at maturity. The improved management had no positive effect on panicle formation, spikelets panicle−1, and harvest index since stress was imposed at the transition period between vegetative and reproductive phases. Our results suggest the appropriate nursery management, for submergence-resilient seedlings to further alleviate damage caused by flash floods and increase the yield of Sub1 varieties in flood-prone rainfed lowlands.

Full textAbstract:
Abstract. Like any gravitationally driven flow that is not constrained at the upper surface, glaciers and ice sheets feature a free surface, which becomes a free-boundary problem within simulations. A kinematic boundary condition is often used to describe the evolution of this free surface. However, in the case of glaciers and ice sheets, the naturally occurring constraint that the ice surface elevation (S) cannot fall below the bed topography (B) (S-B≥0), in combination with a non-zero mass balance rate complicates the matter substantially. We present an open-source numerical simulation framework to simulate the free-surface evolution of glaciers that directly incorporates this natural constraint. It is based on the finite-element software package FEniCS solving the Stokes equations for ice flow and a suitable transport equation, i.e. “kinematic boundary condition”, for the free-surface evolution. The evolution of the free surface is treated as a variational inequality, constrained by the bedrock underlying the glacier or the topography of the surrounding ground. This problem is solved using a “reduced space” method, where a Newton line search is performed on a subset of the problem (Benson and Munson, 2006). Therefore, the “constrained” non-linear problem-solving capabilities of PETSc's (Portable, Extensible Toolkit for Scientific Computation, Balay et al., 2019) SNES (Scalable Non-linear Equations Solver) interface are used. As the constraint is considered in the solving process, this approach does not require any ad hoc post-processing steps to enforce non-negativity of ice thickness and corresponding mass conservation. The simulation framework provides the possibility to divide the computational domain into different subdomains so that individual forms of the relevant equations can be solved for different subdomains all at once. In the presented setup, this is used to distinguish between glacierised and ice-free regions. The option to chose different time discretisations, spatial stabilisation schemes and adaptive mesh refinement make it a versatile tool for glaciological applications. We present a set of benchmark tests that highlight that the simulation framework is able to reproduce the free-surface evolution of complex geometries under different conditions for which it is mass-conserving and numerically stable. Real-world glacier examples demonstrate high-resolution change in glacier geometry due to fully resolved 3D velocities and spatially variable mass balance rate, whereby realistic glacier recession and advance states can be simulated. Additionally, we provide a thorough analysis of different spatial stabilisation techniques as well as time discretisation methods. We discuss their applicability and suitability for different glaciological applications.

Yet the history of the Tourist Hotel Corporation (THC) and its role as the ‘roots’ of the modern hotel industry still tends to be told only as a minor part of our wider tourism story. Recent PhD research [1], based on extensive archive sources and interviews with senior practitioners, argues that the time has come for the THC story to be told in full.
While there have been histories of the tourism and hospitality sector that cover the THC [2–7], they have not included in-depth discussion of the origins, structure and legacies of the organisation. Established in 1955 and sold in 1991, the THC dominated the New Zealand tourist hotel sector for 35 years, running around 10 resort-style properties and setting the standard for service. However, the current dominance of neo-liberal ideology has resulted in the achievements of the Government-owned THC being somewhat dismissed and the role of massive Government investment in the development of our hotel sector often being ‘conveniently’ forgotten. It is common for the THC to be depicted as rather archaic. Burdened with political interference and gross underfunding, the THC is sometimes depicted as a prime example of what happens when the state tries to run a business.
However, this research argues there is a more heroic telling of the THC story, one that celebrates the THC as the fundamental ‘roots’ of the modern hotel sector. The THC was a key player in transforming post-war New Zealand hospitality, raising the bar for service, food and beverage and accommodation significantly. The THC invested heavily in improving buildings, vehicles, equipment and machinery, developing the skills and careers of its staff, and innovating menus. Staff from the THC were seen as ‘A grade’ and many of today’s most successful General Managers learnt their trade in THC properties. Many THC staff also went on to set up influential restaurants outside of hotels during this period.
The THC managed significant tourism development even while showing a profit from 1974 till the late 1980s, posting a 2.7 million dollar surplus in 1986. However, a combination of perceived indebtedness, the 1987 recession and free-market Government ideology resulted in the sale of the THC to the Southern Pacific Hotel Corporation in 1991. The story of the THC involves drama, intrigue, politics, high finance, rapid growth and equally rapid collapse. But most importantly, this is the story of the origins of our hotel industry, showing the huge contribution this state funded group made to the modern industry. Surely it is time this story was told in full, on its own terms and in glorious technicolour.

In the first, empirical part of the paper, we have dealt with the previous recession episodes in Serbia in the 15-year interval from 2006 to 2020 and the direct impact of the Covid-19 crisis. We have compared the long-term and short-term trends and one-off Covid-19 impacts on the real and monetary economy, financial sector, and the rest of the world. Key lessons drawn from the previous crises are highly relevant today. The second part of the paper is analytical. For that purpose, we have updated our DSGE model with the data until the last quarter of 2020 and simulated nine alternative scenarios of fiscal, monetary, and industrial policies over the next five years. They showed remarkable results in some sectors, but created imbalances in others. Focusing on GDP growth in the post-Covid-19 period is misleading since the economy will never be the same. There is a need to choose an optimal mix of conventional policy measures and an industrial policy based on digitalisation and IT. The current Government policy of a huge fiscal deficit and rising public debt exposes the country to unbearable risk in the future.

Full textAbstract:
In the United States, about 36% of all community colleges offer international student programs, of which, about 13% also offer education abroad programs (Malveaux & Raby, 2019). Documentation on community college international education has existed since the 1950s. Advocacy for community college international education is also not new and is found in numerous American Association of Community Colleges publications, association reports, and addresses given by multiple generations of community college leaders who view internationalization as an important way to serve the community college missions of open access, to support gainful employment goals, and to support student success initiatives (American Association of Community Colleges, 2018; Boggs & Irwin, 2007; Gleazer, 1975). In celebration of the Journal of International Students 10th year anniversary, this essay outlines the advances made in community college mobility programs over the past decade. Mobility here refers to both inbound (international student programs) and outbound (education abroad programs).
Community colleges play a critical role in training adults to gain skills needed for participation in a global economy where required job skills change rapidly. This global economy is a context in which international and cross-cultural skills are in high demand. This demand is being addressed by community colleges adding international learning in their academic and in career training curricula and programs. It is also addressed by fostering access to international programs and activities for all students. In 1996, Raby and Tarrow discussed how “with the current recession, the fate of international education is in jeopardy” (p. 20). In 2012, another recession became the backdrop against severe budget cuts that severely impacted periphery programs such as international education (Raby, 2012). Today, the economic context of COVID will once again redefine the number of students who can afford to travel, the ease of travel, and how much infrastructure support will be given by institutions to support international programs. Yet, in learning from the past, it is evident that
…when the global economy stabilized so did internationalization efforts. Even more importantly is that after each crisis period, a new generation of individuals emerged as international advocates and who continually seek to implement changes in the college. Herein lays the promise of the future. (Raby, 2019, p. 16)
The promise of the future rests on research previously conducted on community college internationalization as this research embeds advocacy and best practices so that patterns that work do not need to be reinvented. The community college mission does not have a singular focus as it was designed to serve multiple purposes. Internationalization is one of these missions (Ayers, 2015; Gleazer, 1975; Raby, 2019). This works in harmony with a local mandate to prepare graduates to gain local jobs, even those jobs that are located outside the geographic boundary of the college (Ayers, 2015). Internationalization is included in missions (Whatley & Raby, 2020) and in strategic planning policies (Copeland, 2016).
Open access is a guiding principle that allows enrollment opportunities for all who want to learn. Open access supports current equity agendas. However, equity in international education while encouraging wide-spread enrollment also has limitations. For international students, there are minimum qualifications, including international testing scores and English language proficiencies. Other limitations occur when international students are labeled as a privileged group, which skews the services that they receive (Viggiano et al., 2017). For education abroad, minimum qualifications include grade point average requirements, code of conduct, financial ability, and deficit narratives that stereotype non-traditional students (Whatley & Raby, 2020).
Today, there are dedicated offices and dedicated mid- and senior-level leadership positions that oversee internationalization. This includes partnerships with senior administration (Brennen & Dellow, 2013), with academic departments and campus services (Smith, 2019), and with campus assessment practices (Wood, 2019). There are also known areas for augmentation of support services. For international students, this includes office policies (Lau et al., 2019), student advising practices (Zhang, 2016), addressing marginalization resulting from prejudice and discrimination (Hansen et al., 2018), and understanding the heterogeneity of international students (Bennani, 2018). For education abroad, this includes creative financing (Giammarella, 2012), addressing deficit student labels (Raby, 2019; Robertson, 2019; Whatley, 2019), re-examining entry requirements, including planning time (Amani & Kim, 2017), and understanding when curriculum limits and when it expands free time (McKee, 2019).
Decreased state and federal funding for community colleges complicates the financing of international education offices and accentuates marketing to increase the number of students who enroll in programs, which in turn, directly impacts the larger college budget. Research explains why the college needs to recruit international students (Bohman, 2014), why students want to study in community colleges (Zhang & Hagedorn, 2013), and why myths can negatively impact student success (Budd et al., 2016; Viggiano et al., 2018).
Research also shows that international programs positively influence student success that lead to increased persistence, transfer, and completion. This is true for students who study abroad (Raby et al., 2014; Whatley, 2019) and for international students (Benneni, 2018; Slantcheva-Durst & Knaggs, 2017) whose high academic aspirations help them to overcoming personal challenges (Friedman, 2018).
Since the 1980s, national associations, practitioners, and researchers used advocacy and research to develop and implement best practices. As a result, community college student mobility programs expanded in number and in scope. Today, it is common for colleges to include “international” or “global” in their mission, vision, and annual priorities. There is an increase in full-time dedicated positions for those leading international education, increased access for students to participate in various international programs, expanded use of technologies that further broaden access, and collaborations that extend beyond the campus. Most importantly, students choose to attend community colleges to better themselves, and they make sound decisions to engage in college programs to expand their knowledge, which includes international mobility programs.
In the post-COVID period, it is likely that severe state funding challenges, lower overall and international student enrollments, and high turnover of senior administrators will once again challenge community college international education. I propose that the significant research about community college internationalization has taught five points that will be important drivers in moving international education forward. First, advocacy needs to reinforce that local is not the opposite of global and that international education is indeed one of the community colleges’ missions as it encapsulates an academic shift that promotes international literacy as a critical employability and educational skill. Second, avoid haphazard implementation of services that reinforce hegemonic patterns in which some students are given access to life-altering experiences while others are denied those experiences. Third, eliminate student stereotypes that feed into a negative narrative. Fourth, use caution when designating students as a desirable source of revenue. Finally, understand that the limits of student success are connected to a lack of supportive institutional practices rather than to a lack of student interest. Above all, “Change is a choice needed to be made by visionary leaders who must prioritize and then lead these reform efforts that are sustainable and not impacted by the shifting of time and institutional circumstances (Raby, 2019, p. 17).

Full textAbstract:
Several potential Polish locations for the occurrence of fossil pingos were determined on the basis of analyses of a digital terrain model. Subsequent field reconnaissance connected with drilling into the geological structure, confirmed that one form located NW of Gdańsk, was indeed a fossil pingo. The aforementioned forms occur in a moraine plateau area related to the last ice-sheet retreat towards the Gardno phase moraine. This surface of the plateau is noticeably inclined south-north, at elevations of between 170 and 110 metres. It in fact proved possible to identify more than 80 very well-developed fossil pingos in the area investigated, with each found to consist of a central depression of average diameter 60‒80 m, as surrounded by a rampart 3–7 m high. By drilling into the central parts of the fossil pingos, we found them to be filled with organic sediments up to 6 or 7 m deep. The bottom layer of infill has carbonate and mineral-carbonate gyttjas up to 2 m thick. These are overlain by a peat layer up to 4 m thick, while these organic sediments are underlain by gley till sand. The ramparts are of sandy till frequently intercalated with silty sand. The established sequence of infilling of the central parts of the fossil pingos indicates that, in the immediate aftermath of ice-core melting, these played host to small ponds in which the accumulation of gyttja was able to take place. The gradual accumulation of lake-bottom sediments resulted in a shallowing of the ponds and the development of peat bogs. The morphological image of the above forms and initial drilling in the studied area suggest an association between their genesis and the presence of an ice-cored mound of the pingo type, experiencing subsequent degradation in the direction of the current, fossil pingo, form. Besides the classical, literal morphology of these forms, a decisive argument for acceptance of the above concept is provided by rampart lithology indicating how essential slow processes were in their accumulation. The nature and thickness of the organic infilling in the central part of a post-pingo prove equally important, suggesting an extended period of lake and peat-bog accumulation, probably lasting for the entire Holocene. The aforementioned arguments allow for the precluding of any origin linked with direct human activity (ground construction, bomb craters). The high density and close proximity and morphological similarity of the forms are likewise inimical to an identification as craters caused by above-ground meteorite explosions. Likewise, comparative analysis of the studied forms and kettle holes (usually larger irregularly-shaped larger forms of varied bottom topography) fails to indicate that the ring forms under study here have somehow arisen through the melting of buried dead ice. Analysis of deep boreholes made previously may support a geological structure of the analysed area consisting of a sand layer over 90 metres thick covered by a discontinuous till moraine several metres thick. The thick sand layer in question consists of differently-aged glaciofluvial sediments. This is a hydrogeological window connecting three main Quaternary aquifers and offering a perfect location for the ascension of groundwater. In conditions of developing discontinuous permafrost, this movement led to the creation of pingo forms in open systems on the surface. It is clear that investigation work is not currently at a stage allowing for about as to age to be made, or all details regarding evolution provided. However, the results of planned geomorphological, hydrogeological and geochronological studies should provide for both the recognition and detailed definition of the forms, thereby prompting discussion as to the evolution of permafrost during the late Weichselian transgression and recession in Central Europe.

Abstract I consider two flexible models of earnings dynamics suggested in the recent literature and alternative approaches to the treatment of left-censored observations to examine trends in the permanent and transitory variances of earnings of Canadian male workers from 1985 to 2005. I find that both permanent and transitory variances were higher in the 2000s than in the late 1980s or 1990s. In contrast to the late 1980s and the recession period of the early 1990s, both components of variance grew at a similar pace during the post-recession period, and the share of each component in the total variance remained fairly stable. The results are robust to the choice of a model. The study is based on a large sample from a uniquely rich longitudinal administrative dataset.

Full textAbstract:
Background:In recent times, aesthetics has become a major reason for the patients to seek the dentist. Gingival recession of the anterior teeth leads to long tooth appearance thereby hampering the aesthetics. The aim of the present study is to assess the efciency of modied coronally advanced ap (MCAF) technique in combination with platelet-rich brin (PRF) for recession coverage of Miller's class I and II cases. Materials and method: 10 patients with Miller's class I or class II gingiva were treated by modied coronally advanced ap (MCAF) technique in combination with platelet-rich brin (PRF). The clinical parameters such as gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment level (CAL), width of attached gingiva (WAG), thickness of attached gingiva (TAG) and the height of gingival recession (HGR) were recorded at baseline, 3 months and 6 months follow-up visits. Results: All the clinical parameters showed signicant improvement at 3 months and 6 months post-operatively when compared with the baseline values. The results obtained during the initial follow-up visit remained stable over a period of 6 months. Conclusion: MCAF is a foreseeable technique to achieve gingival recession coverage. Additionally, the use of PRF enables in improved WAG and TAG due to the release of growth factors.

Full textAbstract:
Purpose:To compare the efficiency of bilateral combined resection-recession surgery of the medial rectus muscle versus using a modified Fadenoperation for surgical management of esotropias that totally resolve under general anesthesia, which we called “purely tonic” esotropias.Methods:We included 65 unselected consecutive cases of patients with purely tonic esotropias who underwent surgery between October 2017 and 2018. Patients were divided into group I, who underwent a combined resection and recession of medial recti muscles, and group II, who underwent a bilateral medial rectus Fadenoperation using posterior strapping. A satisfactory outcome was defined as deviation ⩽10 prism diopters (PD), at near and distance fixation, between 3 and 6 months postoperatively.Results:Mean initial deviation was in group I, 19.6 PD and 32.0 PD, in group II, 23.6 PD and 33.5 PD, at distance and near fixation respectively. Postoperatively, in group I, 31 patients (91.2%) showed satisfactory alignment at near and distance fixation. Post-operatively, in group II, 25 patients (80.6%) showed satisfactory alignment at near and distance fixation.Conclusion:Our results suggest both techniques are good options to treat purely tonic esotropias.

Full textAbstract:
In this article, I enquire into the historical circumstances (past and present) under which vulnerability, an embodied and social condition of openness to violence, turns into victimhood, an act of affective communication that attaches the moral value accrued to the vulnerable to everyone who claims it. The 20th-century victimhood, I argue, emerged as a master-signifier of emotional capitalism through the two grand narratives of modernity, psychoanalysis and human rights, each of which tactically mobilizes affective claims to trauma or injury to bestow the moral value of the sufferer to any powerful claimant independent of the position of vulnerability they speak from. Turning to the 21st century, I place victimhood within the communicative context of post-recession and digital neoliberalism to show how the two amplify, accelerate and complicate the circulation of affective claims to suffering, rendering platformized pain a ‘new normal’ of our culture. In order to address the implications of this ‘new normal’ on the most vulnerable in society, I propose the distinction between ‘tactical’ and ‘systemic’ vulnerability as a heuristic frame that enables us to ask questions about who claims to be a victim, from which position and to which effects; and, in so doing, helps us to scrutinize the social contexts in which affective claims to victimhood are made and the power relations such claims reproduce or challenge.

Full textAbstract:
Abstract Background The aim of this study is to investigate three-dimensional quantitative analysis of buccal augmented tissue alterations after surgery using a modified coronally advanced tunnel (MCAT) technique combined with a de-epithelialized gingival graft (DGG) within 1 year post-op, based on intraoral scanning. Methods 25 Cairo class I gingival recession defects were treated using an MCAT technique with DGG. Digital impressions were taken using an intraoral scanner at baseline, 2 weeks, 6 weeks, 3 months, and 1 year after the surgery. Three-dimensional quantitative measurements within 1 year were analyzed for buccal augmented tissue after surgery, including postoperative gingival height gain (GHG), area gain (GAG), volume gain (GVG) and mean thickness (GMT) of region of interest, as well as the tissue thickness change at 1, 2, and 3 mm (TTC1, TTC2, and TTC3) apical to the cemento-enamel junction. Results Postoperative GHG, GAG, GVG, and GMT were distinctly encountered at 2 weeks post-op, then gradually decreased. At 1 year, GHG, GAG, GVG, and GMT were 2.211 ± 0.717 mm, 7.614 ± 2.511 mm2, 7.690 ± 4.335 mm3 and 0.965 ± 0.372 mm, respectively. Significant decreases were recorded between 6 weeks and 1 year in terms of GHG, GAG, and GVG. The GMT was sustained after 6 weeks with an increase of nearly 1 mm at 1 year. TTC1 and TTC2 yielded thicker tissue change than TTC3. Conclusions Three-dimensional quantitative measurements taken via intraoral scanning showed that buccal augmented tissue acquired via MCAT with DGG tends to be stable after 3 months post-op. Digital measurement can be applied in periodontal plastic surgery as a clinically feasible and non-invasive evaluation method for achieving volumetric outcomes.
