Modified maxillary sinus floor elevation via a mini-lateral window with simultaneous placement of dental implants : a clinical and radiographical study

This study assessed the effectiveness of modified sinus floor elevation via a mini-lateral window with simultaneous placement of implants in 20 patients with severely atrophic maxilla. Patients received mini-roundlike or a mini-slot osteotomy which was done to establish an access on the lateral sinus wall for placement of bone grafts depending on the number of inserted implants and the characteristics of sinus floor. Clinical and radiographic parameters were collected. Results showed all implants were well maintained, with 100% cumulative success rate. The mean residual, immediate and 6-month postoperative augmented bone height was 3.0 ± 0.5, 13.6 ± 0.9, and 13.2 ± 0.8 mm, respectively. Intra-operative and 6-month postoperative implant stability quotient (ISQ) were 61.2 ± 3.7 and 76.8 ± 2.4, respectively. No significant differences were found in clinical outcomes between two types of window approaches. Sinus augmentation via a mini window with simultaneous placement of implants has a higher success rate, may improve clinical outcome and thus can be used as a reliable treatment for severely atrophic maxilla.
Dynamic hysteresis modelling of soft magnetic materials for automotive applications

In the work presented the study about the most used dynamic hysteresis models for the ferromagnetic materials usually exploited in electrical vehicles is first focused. Among them, we propose an approach for the simulation of dynamic scalar magnetization processes based on the solution of the diffusion equation. This model will be used for the estimation and prediction of the magnetic losses in a sample of Non-Oriented (NO) iron-silicon steel with pulse width modulation (PWM) excitations, in the typical frequency range of interest for automotive. Comparative analysis with measurements using a Single Sheet Tester (SST) is reported.
[Determination of the dynamic levels of interleukin-8 in gingival crevicular fluid of porcelain teeth with three different alloys].

OBJECTIVE To study the interleukin-8 (IL-8) levels in gingival crevicular fluid (GCF) of porcelain teeth coated with Ni-Cr, Co-Cr or gold alloy at different time periods, and to uncover the degree of stimulation by these alloys on gingiva at different time periods. METHODS 45 cases of porcelain teeth coated with Ni-Cr, Co-Cr or gold alloy were selected randomly, with 15 cases in each group. Sandwich enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration and total amount of IL-8 in GCF. The assay was done before treatment, as well as at 1, 3 and 6 months post-treatment. RESULTS The total amounts of IL-8 and GCF volume in the Ni-Cr alloy coated porcelain teeth were higher in different time period than those before treatment (P<0.05). However, the IL-8 levels in Co-Cr and gold alloy coated porcelain teeth returned to pre-dental restoration after 3 months. Otherwise, the levels of IL-8 concentration in GCF showed no significant difference among the three different alloys coating at different time periods. CONCLUSION IL-8 is an important cytokine during tissue inflammation. Therefore, the level of IL-8 in GCF is a useful criteria for the evaluation of stimulation degree on gingiva by different alloy coating materials in porcelain teeth. The clinical choice of different alloy coating for porcelain teeth should be considered accordingly.
A Catering Theory of Earnings Management

We propose that earnings management is driven by the prevailing investor demand for earnings surprises. Managers cater to investors by inflating earnings in periods when investors react optimistically to positive earnings surprises relative to negative earnings surprises and report more conservatively when investors react pessimistically to earnings news. Using aggregate market-level data, we find that the propensity to use income-increasing abnormal accruals is higher (lower) in quarters when proxies for investors' response to positive earnings surprises relative to negative earnings surprises is higher (lower). Further analysis suggests that investor sentiment might at least partly account for the relation between abnormal accruals and investors' earnings optimism.
The Design of Financial Maintenance Covenants

This article focuses on financial maintenance covenants as incentive instruments for borrowers under both moral hazard and adverse selection. We explain why maintenance covenants are conditioned on public information. We examine the effect of the firm's incentive to risk-shift, debt amount, and renegotiation costs on optimal covenants. In an extension of the model, we find that a reduction in financial signal quality 1) moves the equilibrium from pooling to separating, to no covenants at all, and 2) has a non-monotone effect on covenant strictness. We also allow for uncertainty in macroeconomic conditions and characterize state contingent covenants within our framework.
Impact of Foreign Banks

This paper provides a critical assessment of the costs and benefits of foreign bank ownership. It reviews the extensive literature on the impact of foreign banks and uses a unique database on bank ownership, covering 129 countries, to (re-)examine a number of the issues discussed. It documents (changes in) foreign bank presence between 1995 and 2009, highlighting important differences across host and home countries and strong bilateral patterns. It finds that foreign banks tend to outperform domestic banks in developing countries, countries with weak institutions and where foreign banks do not play a major role. In addition, being from a geographically close home country increases the profitability of foreign banks. In terms of impact, it shows that foreign banks can deter domestic financial sector development in developing countries, countries with weak institutions and where foreign banks play a minor role. Examining the impact of foreign banks on financial stability, it finds that during the global crisis, foreign banks reduced credit more compared to domestic banks in countries where they had a small role, but not when dominant or funded locally. These findings show that, when analyzing the impact of foreign bank presence accounting for heterogeneity, including bilateral ownership, is crucial.
Corpus callosotomy for epilepsy.

Eighteen uncontrolled epileptic patients had neuropsychological evaluation before and after partial or total corpus callosotomy. In patients with early-onset seizures and signs of severe unilateral CNS dysfunction, callosotomy produced no deficits and several improvements. AH patients whose language-dominant hemisphere did not control their dominant hand had impairments in some aspect of speech and language function after callosotomy. In some patients, unilateral deterioration of motor function was observed, and was associated with mild to moderate dysfunction in the contralateral hemisphere (ie, memory impairment or preexisting hemiparesis). Postoperative deficits occurred with partial, as well as total, section.
Surveying Data on Consumer Green Purchasing Intention: A Case in New Zealand

Many people have expressed their environmental concerns, and agreed that immediate actions should be taken for the environment. However, only few of them would always make their purchasing decision based on their environmental concerns. Grounded in the theory of Planned Behavior, the aim of this research was to examine the discrepancy between New Zealand consumersâ€™ environmental concerns and intentions to purchase energy-saving light bulbs. The study employed a cross-sectional consumer survey (between late 2011 to early 2012) for data collection (N=313), and the structural equation modelling for model testing. Further, the study also took precautions during the questionnaire design stage to minimize potential common method bias, and examined the common method variance in the data before testing the model. All indicators in this research were reflective to their representing constructs. Results of the analysis confirmed that consumersâ€™ attitudinal affections and beliefs towards the purchasing behavior, self-identity, and past purchasing behavior had positive influence on their purchasing intentions.
Too much of a good thing? Absorptive capacity, firm performance, and the moderating role of entrepreneurial orientation

Absorptive capacity (ACAP) refers to a firm's ability to acquire, assimilate, transform, and exploit new knowledge. Research has yet to acknowledge the possibility of limits to the financial returns of this important strategic construct. This study suggests an inverted-U shaped relationship between ACAP and financial performance. Based on data from 285 technology-based small and medium enterprises, we observe gains within three prospective, secondary measures of growth to diminish beyond lower levels of ACAP, even turning negative and becoming harmful beyond intermediate levels. We find that entrepreneurial orientation (EO) moderates the ACAP-performance relationship, enhancing financial gains at lower levels of ACAP and mitigating the decline in financial performance at higher levels of ACAP. Further, with higher EO, higher ACAP can be achieved before financial returns diminish.Copyright © 2012 John Wiley & Sons, Ltd.
Solving distribution feeder reconfiguration and concurrent dg installation problems for power loss minimization by multi swarm cooperative PSO algorithm

This paper presents a novel combinational approach to network reconfiguration and DG installation problems for power loss minimization in distribution network. A multi swarm cooperative population based PSO method is used keeping in view the complexity of maintaining the radial structure and operational constraints. Multi swarm cooperative particle swarm optimization (MC-PSO) algorithm is an extension of PSO algorithm which is based on the cooperative behavior of different organisms living in an eco-system for surviving. The optimal points for DG installation and DG sizing are carried out simultaneously. Different approaches for loss minimization are undertaken and compared with each othIEEE 33-bus and 69-bus test systemser. The effectiveness of the approach is tested with IEEE 33-bus and 69-bus test systems with encouraging results.
Reliability of the worker role interview.

The Worker Role Interview is a semistructured interview designed to be used as the psychosocial-environmental component of the initial rehabilitation assessment for the injured worker. Interrater reliability of the Worker Role Interview was computed for three raters for a sample of 30 adult subjects receiving rehabilitation due to an upper extremity injury. Reliability was assessed with the intraclass correlation approach. The coefficients estimating interrater reliability for six content areas ranged from . 46 to . 92 with a total value of . 81. Three out of six content areas received ratings well below the accepted standard of . 80, suggesting further need for instrument refinement in select areas. Test-retest reliability was computed for one rater for a sample of 20 subjects. The intraclass coefficient values ranged from . 86 to . 94 with a total value of . 95 indicating high test-retest reliability.
Residual Claims and Incentives in Restaurant Chains

I examine the relationship between ownership and production activities using a new dataset of restaurant chains. Production in restaurant chains provides an opportunity to examine the effects of residual claims on incentives because production is decentralized and fairly uniform across restaurants in the same chain. Yet the allocation of residual claims varies between company-owned and franchised units, affecting the strength of incentives for restaurantlevel activities. The decision to own or franchise each restaurant reflects the value of either withholding or allocating residual claims for performing these activities. I find that more complex production activities are systematically correlated with company ownership. Onsite food production raises the likelihood of company ownership by 28% relative to offsite food production. Table service raises the likelihood of company ownership by 26% relative to counter service. The results are not consistent with straightforward effort-promoting effects of residual claims in simple principal agent models. They are consistent with the view that residual claims can generate unbalanced incentives across diverse tasks.
Selective Changes in Executive Functioning Ten Years After Severe Childhood Traumatic Brain Injury

Pediatric traumatic brain injury (TBI) impacts on children's executive functions, but little is known of how such deficits evolve in the long term. Forty adolescents with TBI were assessed ten years post-injury and compared to 19 typically developing participants on a range of executive measures (attentional control, cognitive flexibility, goal setting, information processing). Children with mild or moderate TBI performed within age expectations on all tests; however, those with severe injuries had poorer performance on goal setting and processing speed tasks. Childhood TBI may result in subtle lasting changes in complex executive skills, which could require ongoing support into adulthood.
Intrafirm Knowledge Transfer and Employee Innovative Behavior: The Role of Total and Balanced Knowledge Flows

Research on intrafirm knowledge transfer has generally found a positive impact of knowledge inflows on the innovation of an organizational unit. However, the role of knowledge outflows during knowledge transfer is less clear. This paper argues that knowledge outflows influence innovation through a self-learning mechanism and a fairness assessment mechanism, and play a unique and important role on team innovation. Based on this new understanding on knowledge outflows, it is necessary to examine the impacts of inflows and outflows simultaneously in innovation research. This paper expresses the sum and difference of knowledge inflows and outflows as total and balanced knowledge flows. A theoretical model is proposed to examine the distinct and synergistic effects of total and balanced knowledge flows on employees' innovative behavior of an organizational unit. The model was tested on 148 retail units of an apparel firm based on survey responses from both shop managers and staff. Results showed that total and balanced flows have independent direct effects and a synergistic effect on employee innovative behavior: employees of a unit had the highest levels of innovative behavior when knowledge flows were high and balanced at the same time. This paper contributes to the literature by taking into account both the direction and magnitude of knowledge transfer to examine team innovation.
The impact of supply chain integration on firm performance

Purpose – This paper aims to provide empirical evidence of the effectiveness of various supply chain integration (SCI) practices under different competitive strategies in terms of cost leadership and differentiation. Design/methodology/approach – Survey methodology was used to collect data from 604 Chinese manufacturers. Hierarchical linear regression was used to analyze the moderating effects. Findings – The results showed that competitive strategies significantly influenced the effectiveness of SCI practices, including internal, process and product integration. More specifically, internal integration significantly affected the financial performance of cost leaders, while process integration contributed more to the financial performance of differentiators. However, competitive strategies had no significant moderating effect on the relationship between SCI and operational performance. Research limitations/implications – This study contributes to the literature by exploring the effectiveness of various SCI.
Transcriptional regulation of macrophage cholesterol trafficking by PPARα and LXR

PPARs (peroxisome-proliferator-activated receptors) and LXRs (liver X receptors) are ligand-activated transcription factors that control lipid and glucose metabolism, as well as the inflammatory response. Since the macrophage plays an important role in host defence and immuno-inflammatory pathologies, particular attention has been paid to the role of PPARs and LXRs in the control of macrophage gene expression and function. Altered macrophage functions contribute to the pathogenesis of many infectious, immunological and inflammatory disease processes, including atherosclerosis. Research over the last few years has revealed important roles for PPARs and LXRs in macrophage inflammation and cholesterol homoeostasis with consequences in atherosclerosis development. This review will discuss the role of these transcription factors in the control of cholesterol trafficking in macrophages.
Prevalence and Reasons for Initiating Use of Electronic Cigarettes Among Adults in Montana, 2013

We used data from the 2013 Montana Adult Tobacco Survey to estimate the prevalence of electronic cigarette (e-cigarette) use and reasons for initiation among Montana adults. More than 1 in 10 (11.2%, 95% confidence interval [CI], 9.1%–13.2%) adults reported ever using e-cigarettes, and 1.3% (95% CI, 0.7%–1.9%) reported current use. Most respondents reported “trying something new” (64%) or “trying to quit or reduce cigarette use” (56%) as a reason for initiating use. Ongoing surveillance of these addictive products is needed.
The effect of electronic word of mouth on brand image and purchase intention

Purpose – Word‐of‐mouth (WOM) has been recognized as one of the most influential resources of information transmission. Advances in information technology and the emergence of online social network sites have changed the way information is transmitted. This phenomenon impacts consumers as this easily accessible information could greatly affect the consumption decision. The purpose of this paper is to examine the extent to which e‐WOM among consumers can influence brand image and purchase intention in the automobile industry.Design/methodology/approach – Measurement items are adapted from existing scales found in the marketing literature. Academic colleagues reviewed the items for face validity and readability. The scales are evaluated for reliability, convergent validity, and discriminant validity using data collected in a survey of Iran Khodro's prospective customers in Iran. A structural equation modeling procedure is applied to the examination of the influences of e‐WOM on brand image and purchase inte.
A decade of hospital-based violence intervention: Benefits and shortcomings

INTRODUCTION Initial analyses of hospital-based violence intervention programs (VIPs) have demonstrated decreased violent injury recidivism. Long-term VIP performance has not been assessed. Violence intervention program quality improvement requires evaluation to identify shortcomings and client subpopulations warranting additional resources. We evaluated our case manager–based VIPs to identify modifiable risk factors that most impact violent injury recidivism and determine subpopulations that need modification of targeted services. METHODS Data on demographic variables, socioeconomic factors, needs, and injury recidivism from 2005 to 2014 were collected through our VIP database. Possible client needs included housing, education, employment, court advocacy, driver’s license obtainment, and “other. ” Case managers assessed needs as “not needed,” “identified (unmet),” and “met. ” &khgr;2 And nonparametric tests were used to identify factors associated with recidivism reduction. RESULTS Over the 10-year period, 466 clients were enrolled in VIP. During the program period, the violent reinjury rate was 4%, as compared with a historical control of 8% from 2000 to 2004. Women had lower rates of reinjury than men (3% vs 13%, respectively, p = 0.023). Blacks had the lowest recidivism (2%, p < 0.0001), whereas a higher rate (11%) was observed among Latinos. Although a minority of clients (5%), 100% of white clients were reinjured. Mental health services (51%), victim-of-crime compensation (48%), employment (36%), and housing (30%) were the most frequently identified needs. Expressing the need for education was significantly associated with likelihood of reinjury, an effect that was completely reversed when the need was met. CONCLUSION This evaluation of a VIP demonstrates sustained recidivism reduction and success in addressing client needs from a traditionally underserved population. Efforts to identify and address root causes of Latino and white client reinjury should be increased. Violence intervention program prioritization of housing needs may reduce future reinjury. This study demonstrating sustainable success underscores the importance of increased integration of VIP into trauma centers nationally. LEVEL OF EVIDENCE Therapeutic study, level III.
Dreams as Modifiers and Tests of Mental Schemas: An Emotional Selection Hypothesis

A process is proposed that helps a person adapt to a social environment. During sleep, this process executes a set of dreams with social content that schemas tentatively incorporate by self-modifying. Due to vast interConnectivity that exists amongst social schemas, such modifications may introduce accidental, maladaptive conflicts. Consequently, a second set of dreams is executed in the form of test scenarios in order to evaluate the schema modifications effected by the first set of dreams. The process would monitor emotions generated during these latter dream tests. If prior, tentative modifications alleviate anxiety, frustration, sadness, or in other ways appear emotionally adaptive, they would be selected for retention. Those modifications that compare negatively to existing, unchanged schemas would be abandoned or further modified and tested. The correspondences of these hypotheses to the sleep cycle, previous dream studies, and functional neurological processes are discussed.
Associations among physical activity, body mass index, and health‐related quality of life by race/ethnicity in a diverse sample of breast cancer survivors

Health‐related quality of life (HRQOL), body mass index (BMI), and physical activity (PA) levels have all been associated with prognosis following breast cancer and may explain partially the higher mortality for breast cancer in certain racial/ethnic subgroups. In this study, associations between PA, BMI, and HRQOL by race were examined in a sample of breast cancer survivors.
Chemical and nutritive changes in herring meal during storage at different temperatures with and without antioxidant treatment.

Herring meals prepared with and without the addition of 0.025% of 1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline (EQ) were stored for ten months at -20 oC and 21 oC. Storage changes in the biologically determined energy and protein values of the meals were monitored and related to changes in the chemical characteristics of the meal. Antioxidant treatment stabilised the meal lipid against oxidative changes resulting in loss of solubility, decline in iodine value and formation of peroxides and malonaldehyde. The effect of storage temperature on the course of oxidation depended upon whether the meal was treated with EQ. Lipid in meals without EQ tended to show greater change early in the storage period at -20 oC. Antioxidant-treated meals showed protection of the protein against changes leading to reduced digestibility and lysine availability. Either antioxidant treatment or storage at -20 oC protected the biological availability of the energy-supplying nutrients present in the meal.
