University of Groningen Implant decontamination during surgical peri-implantitis treatment

Aim: The objective of this randomized, double-blind, placebo-controlled trial was to study the effect of implant surface decontamination with chlorhexidine (CHX)/ cetylpyridinium chloride (CPC) on microbiological and clinical parameters. Material & Methods: Thirty patients (79 implants) with peri-implantitis were treated with resective surgical treatment consisting of apically re-positioned flap, bone recontouring and surface debridement and decontamination. Patients were randomly allocated to decontamination with 0.12% CHX + 0.05% CPC (test-group) or a placebo-solution (without CHX/CPC, placebo-group). Microbiological parameters were recorded during surgery; clinical and radiographical parameters were recorded before (pre-) treatment (baseline), and at 3, 6 and 12 months after treatment. Results: Nine implants in two patients in the placebo-group were lost due to severe persisting peri-implantitis. Both decontamination procedures resulted in significant reductions of bacterial load on the implant surface, but the test-group showed a significantly greater reduction than the placebo-group (log 4.21 1.89 versus log 2.77 2.12, p = 0.006). Multilevel analysis showed no differences between both groups in the effect of the intervention on bleeding, suppuration, probing pocket depth and radiographical bone loss over time. Conclusion: Implant surface decontamination with 0.12% CHX + 0.05% CPC in resective surgical treatment of peri-implantitis leads to a greater immediate suppression of anaerobic bacteria on the implant surface than a placebo-solution, but does not lead to superior clinical results. The long-term microbiological effect remains unknown. Yvonne C. M. de Waal, Gerry M. Raghoebar, James J. R. Huddleston Slater, Henny J. A. Meijer, Edwin G.

Hotel Brand Standards: How to Pick the Right Amenities for Your Property

Amenities specified by hotel companies’ brand standards can become a point of contention between hotel owners and brand managers. At issue for the owner is whether offering a particular amenity justifies the expense, while brand managers are typically more concerned with maintaining consistent brand standards systemwide. This report provides another perspective, by analyzing the short-term return on investment for six upscale and luxury brands offering three popular complimentary amenities—bottled water, internet access, and fitness center use—both in terms of their effects on first-time visits and on repeat business. While internet access held the greatest attraction for first-time guests, complimentary bottled water offered the highest ROI for returning guests. Analyzed over a twelve-month period, the fitness center had a negative ROI for both groups. Of particular interest, the study also found that guests greatly overestimated the likelihood that they would use the hotels’ amenities.
Analysis of glamorous acquisitions in the telecommunications sector: Overvaluation or success?

This article analyses the performance and value creation of the glamorous operations of mergers and acquisitions (M&A) in the telecommunications sector, trying to understand if the glamour company´s M&A operations conduct to the stockholder wealth maximization, and the role of acquirer´s characteristics and its behaviour as glamour firm. After calculating the abnormal returns of telecommunications M&A from 2000 to 2010 and evaluating the value creation/destruction of these operations, we conclude that glamour tends to be opposite to value creation in the long run. The glamour firms show significant value destruction in certain timeframes and worse performance than non-glamour firms. From our analysis, it is evident that certain acquirers´ characteristics, such as size, are determinant in the glamour behavior. Related to this, the influence of the intangible assets (and particularly the intangible ratio) is a new contribution from this analysis.
Too Much of a Good Thing? Risk Disclosure and Corporate Innovation

Consistent with theoretical models that show disclosure can reduce uncertain investments, we find that mandating risk disclosure is negatively associated with corporate innovation. Using a textual analysis of a large sample of 10-K filings for US firms, we identify a negative relationship between risk disclosure and firm-level investments in R&D and innovation output in terms of patents and citations. Furthermore, the channel for this decline seems to be linked to financial constraints, with risk disclosure having a larger impact on innovation among firms with financial constraints. These results suggest that a mandatory risk disclosure requirement can have unintended real consequences for firms making uncertain investments, such as innovation.
Hepatocellular carcinoma: detection with gadolinium- and ferumoxides-enhanced MR imaging of the liver.

PURPOSE To test the hypothesis that the accuracy of gadolinium- and ferumoxides-enhanced magnetic resonance (MR) imaging is different in small (< or =1.5-cm) and large (>1.5-cm) hepatocellular carcinomas (HCCs). MATERIALS AND METHODS Forty-three consecutive patients with chronic liver disease were enrolled in this study. The imaging protocol included unenhanced breath-hold T1-weighted fast field-echo sequences, unenhanced respiratory-triggered T2-weighted turbo spin-echo (SE) sequences, dynamic gadolinium-enhanced T1-weighted three-dimensional turbo field-echo sequences, and ferumoxides-enhanced T2-weighted turbo SE sequences. Images of each sequence and two sets of sequences (ferumoxides set and gadolinium set) were reviewed by four observers. The ferumoxides set included unenhanced T1- and T2-weighted images and ferumoxides-enhanced T2-weighted turbo SE MR images. The gadolinium set included unenhanced T1- and T2-weighted images and dynamic gadolinium-enhanced three-dimensional turbo field-echo MR images. In receiver operating characteristic (ROC) curve analysis, the sensitivity and accuracy of the sequences were compared in regard to the detection of all, small, and large HCCs. RESULTS Imaging performance was different with gadolinium- and ferumoxides-enhanced images in the detection of small and large HCCs. For detection of small HCCs, the sensitivity and accuracy with unenhanced and gadolinium-enhanced imaging (gadolinium set) were significantly (P =.017) superior to those with unenhanced and ferumoxides-enhanced imaging (ferumoxides set). The area under the composite ROC curves, or A(z), for the gadolinium set and the ferumoxides set was 0.97 and 0.81, respectively. For large HCC, the ferumoxides set was superior compared with the gadolinium set, but this difference was not statistically significant. Analysis of all HCCs demonstrated no significant differences for gadolinium- and ferumoxides-enhanced imaging. CONCLUSION For the detection of early HCC, gadolinium-enhanced MR imaging is preferred to ferumoxides-enhanced MR imaging because the former demonstrated significantly greater accuracy in the detection of small HCCs.
Genetic mapping1 of the mouse homologue of the human angiopoietin-1 gene (Agpt) to mouse chromosome 9E2 by in situ hybridization

Angiogenesis is characterized by partially overlapping phases: a) initiation, characterized by vascular leakage, b) progression during which endothelial cells migrate and proliferate, c) differentiation into primitive capillaries and d) maturation characterized by recruitment of mesenchymal cells and extracellular matrix remodeling (Bussolino et al., 1997; Hanahan, 1997). The last step of angiogenesis has been suggested to be mediated through angiopoietin-1 (Angpt-1) via its tyrosine kinase receptor Tie2, that is expressed only on endothelial cells and early hemopoietic cells (Davis et al., 1996; Dumont et al., 1992; Iwama et al., 1993). The Angpt-1 gene (ANGPT1) has been localized on human chromosome 8q22.3→q23 (Grosios et al., 1999) by radiation hybrid analysis and FISH with a PAC 1 probe containing ANGPT1. In this study the localization of the Angpt-1 gene (Agpt) on mouse chromosomes was mapped by indirect in situ PCR in order to investigate its conservation in the mouse model and to look for homology within human and mouse chromosomes.

Correlates Attitude towards Adoption and Re-Invention Technology of Small Rubber Farmers in Dhalai District of Tripura

Rubber is one of the major plantation crops in Tripura since it was raised for the first time in Tripura in 1963 by the State Forest Department. Tripura Forest Development & Plantation Corporation Ltd. (TFDPC), a State Government Undertaking established in 1976, adopted rehabilitation of degraded forests through rubber plantation as its primary objective. Rubber has been identified as one of the thrust areas in Tripura, in view of its suitability to the terrain and the acceptability amongst the people. Tripura now stood as a second largest rubber growing state of India after Kerala both in terms of area as well as production and has emerged as the forerunner among the non-traditional rubber growing regions with 61231 ha of plantation and 37277 tonnes of production in 2012-13 (Govt of Tripura, 2015). Rubber plantation has taken a paradigm shift in shaping the standards of livelihood systems and thus secured a way for farmers to gain constant income. The relative success of rubber in Tripura can be attributed to its economic viability; effective extension and institutional support in production and marketing by the Rubber Board; along with the decline and uncertainty in tea and horticulture crops International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 10 (2017) pp. 3145-3150 Journal homepage: http://www.ijcmas. com
Towards an Economic Approach to Identity and Access Management Systems Using Decision Theory

Nowadays, providing employees with failure-free access to various systems, applications and services is a crucial factor for organizations’ success as disturbances potentially inhibit smooth workflows and thereby harm productivity. However, it is a challenging task to assign access rights to employees’ accounts within a satisfying time frame. In addition, the management of multiple accounts and identities can be very onerous and time consuming for the responsible administrator and therefore expensive for the organization. In order to meet these challenges, firms decide to invest in introducing an Identity and Access Management System (IAMS) that supports the organization by using policies to assign permissions to accounts, groups, and roles. In practice, since various versions of IAMSs exist, it is a challenging task to decide upon introduction of an IAMS. The following study proposes a first attempt of a decision support model for practitioners which considers four alternatives: Introduction of an IAMS with Role-based Access Control RBAC) or without and no introduction of IAMS again with or without RBAC. To underpin the practical applicability of the proposed model, we parametrize and operationalize it based on a real world use case using input from an expert interview.
Editor’s presentation

Despite the well-known benefits of exercise-based cardiac rehabilitation, the most efficient modality and intensity are still under discussion. A meta-analysis showed that high intensity interval training was more efficient than moderate intensity continuous training on peak oxygen consumption (VO2) gain of patients with coronary artery disease. However, when the studies with an isocaloric exercise training protocol were analysed, the superiority of the high intensity exercise training on peak VO2 disappeared. Furthermore, the quality of life showed no difference on physical, emotional and social domains between groups. Thus the total energy spent on exercise training is probably more important than exercise intensity. However, this review also highlighted the paucity of high-quality research addressing exercise modality. The accompanying editorial underscores the need for properly designed trials, focusing on long-term physical activity engagement and effectiveness of interval training, its effect on mortality as well as the feasibility and safety of high intensity exercise implementation in real-life regimens.
Clustering in Ireland: development cycle considerations

Abstract Motivated by ongoing research into the cluster concept that considers dynamic features of economic development and the cluster life cycle, differences between traded clusters and local activity across different spatial scales are examined for Ireland. Using recent cluster definitions for Europe, this paper presents clustering patterns within the Irish economy from 2008 to 2012. We report on data requirements when applying the benchmark cluster definitions to Irish data. Integrating small, open economy features with life-cycle concerns, we focus on specific clusters in Ireland, along with their export performance, noting that appropriate cluster boundaries are neither regional nor national. Analyses indicate that while Ireland hosts a number of internationally competitive clusters, foreign-owned firms remain substantially more productive than indigenous enterprises. We identify the geographical location of these prominent clusters at the NUTS-3 regional level and highlight the role of regional features for differences in adaptive cycles of clusters. We identify a substantial portion (60%) of Irish regional wage variation relates to the different cluster mixes across regions.
Data and information management : manual three

Data and information management refers to the development, collection, use, and preservation of data and the methods needed to acquire, control, protect, deliver, and enhance its value to achieve the goals of agricultural insurance programs. Issues related to the collection, development, updating, and quality of data are often overlooked when developing agricultural insurance programs. However, such programs will likely fail without a concise, well-developed plan for data and information management. Data are needed by those who develop, operate, and manage agricultural insurance programs. In addition, agricultural producers need access to high-quality data for making individual purchase decisions. Better data quality and larger data quantities improve decision-making, management, and product development. Successful agricultural insurance programs require accurate and comprehensive data collection, management, and security. This manual presents a wide range of management issues related to agricultural insurance data. Specifically, issues related to data uses, needs, documentation, quality control, security, accessibility, storage, and public policy is discussed. In addition, data needs related to underwriting, loss adjustments, premium rating, and reinsurance are also presented. Because specific agricultural insurance products often have differing data requirements, similarities and differences among such products are delineated. Finally, this manual also considers computer hardware and software design issues and requirements and provides examples of necessary data files.
Isolation,Culture and Identification the 11 Endophytic Fungus from Oxytropis glabra DC.

Leaves and stems were cut from individual plants of Oxytropis glabra DC. ,and used as materials to isolate and culture the endophytic fungus in vitro.The microbiological morphology of colony and the conidiophore were investigated.The 5.8SrDNA/ITS of the in vitro cultured endophytic fungi were sequenced,and then the sequence data of the endophytic fungi were submitted to GenBank and analysed by homologous blast.The phylogenetic tree was constructed by MegAlign of DNASTAR software package.The molecular biological and microbiological characters were investigated in order to predict the classification of the endophytic fungi.The results indicated that the morphologic characteristics of the colony and conidiophore of this 11 endophytic fungi were the same as that of Embellisia sp.L12. The sequences of ITS1 and 5.8SrDNA of endophytic fungus from Oxytropis glabra DC.were totally the same.Compared to the sequence of Embellisia sp.L12,there was only one viriation site which was in the 5.8SrDNA region in each sequence.In addition,two variation sites were shown in the ITS2 region.It was presumed that the endophytic fungi had a close relationship to Embellisia,but the classification of the endophytic fungi need further research.
Closed-Loop control of DC-DC buck converters based on exact feedback linearization

Exact feedback linearization technique is applied to standard DC-DC buck converter using precise model of the system. Considering parasitic resistances of the inductor, capacitor and switches, averaged state space method is used to develop converter model. Hence, developed controller is able to regulate output voltage of the converter in a wide range of operation. Using the optimal control theory, the coefficients of the developed controller are optimized. In order to evaluate the accuracy and effectiveness of the proposed method, designed controller is simulated using MATLAB/Simulink toolbox. Presented simulation results prove that the developed controller has acceptable dynamic and steady-state responses.
The role of subsidy payments in the uptake of forestry by the typical cattle farmer in Ireland from 1984 to 2012.

Since the 1980’s, forestry has been growing as a land use in Ireland due largely to financial incentives offered to farmers to convert land from agriculture to forestry. Cattle farmers are the group that may financially benefit most from planting and have been found to be more interested in establishing forests. This makes cattle systems the most relevant alternative land use to compare with forestry. Previous examinations of afforestation trends have recognised the importance of competing subsidies on understanding the relatively low uptake of forestry supports but no detailed examination of this issue has been undertaken to date. The primary goal of this study was to review, quantify and compare annual cattle and forestry subsidies for a typical farm over the period 1984 to 2012. Eligibility and payment changes were examined for both forestry and agricultural subsidies over this period and form the basis of a subsidy model. The relative effect of forestry and agricultural subsidies on income is modelled for a “typical” farm using a hypothetical model, which facilitates direct comparison on an area basis. The results show that the loss of agricultural supports could have been substantial for a typical cattle farm for most of the period examined. This novel finding may assist in understanding afforestation rates to date.
After the Override: An Empirical Analysis of Shadow Precedent

Congressional overrides of prior judicial interpretations of statutory language are typically defined as equivalent to judicial overrulings, and they are presumed to play a central role in maintaining legislative supremacy. Our study is the first to empirically test these assumptions. Using a differences-in-differences research design, we find that citation levels decrease far less after legislative overrides than after judicial overrulings. This pattern holds true even when controlling for depth of the superseding event or considering only the specific proposition that was superseded. Moreover, contrary to what one might expect, citation levels decrease more quickly after restorative overrides—in which Congress repudiates the prior Supreme Court decision as incorrect—than after overrides intended to update or clarify the law. This suggests that ongoing citation of overridden precedents, what we call shadow precedents, may be driven more by information failure or ambiguity than by ideological disagreements between the branches of government.
High- versus low-top shoes for the prevention of ankle sprains in basketball players

Using a prospective, randomized experimental design, 622 college intramural basketball players were stratified by a previous history of ankle sprains to wear a new pair of either high-top, high-top with inflatable air cham bers, or low-top basketball shoes during all games for a complete season. Subjects were asked to complete a history questionnaire and were given a complete ankle examination. They were allowed to wear these shoes only during basketball competition. Followed over the course of a 2-month intramural season, 15 ankle injuries occurred during 39,302 minutes of player-time: 7 in high-top shoes, 4 in low-top shoes, and 4 in high-top shoes with inflatable air chambers. The injury rates (injuries per player-minute) were 4.80 × 10-4 in high-top shoes, 4.06 x 10-4 in low-top shoes, and 2.69 x 10 -4 in high-top shoes with inflatable air chambers. There was no significant difference among these 3 groups, leading to the conclusion that there is no strong rela tionship between shoe type and ankle sprains.
Role of Organisational Culture in Open Innovation: An Empirical Study of Service Sector Organisations in Sri Lanka

Innovation underpins the process of bringing novel products and services to market and is critical to a firm's viability, competitive advantage and performance. Open innovation has been proposed as a new paradigm for the management of innovation. Success in this open innovation paradigm offers great benefits to business organisations. Many firms have succeeded in the open innovation paradigm but failures have also been reported. Being a new area of research, not much is known about the factors affecting open innovation. In view of this, the current research was conducted with the aim to study the effects of organisational culture on open innovation. The main purpose of the study was to identify organisational culture types which enable and retard both in-bound open innovation and out-bound open innovation. Cross-sectional data were collected using the survey method from 124 middle and top managers working in finance and information technology sectors in Sri Lanka. The data analysis has been done using the statistical software packages of SPSS and AMOS. Both cluster analysis method and hierarchical multiple regressions were employed to test the hypothesised relationships. Highly integrative culture was found to relate positively to in-bound open innovation. No evidence of a significant relationship between highly integrative organisational culture and outbound open innovation was found. Hierarchy culture related negatively to both in-bound open innovation and out-bound open innovation. This research paper is probably the first empirical study which investigates the role of organisational culture in open innovation in the Sri Lankan context. Practical implications for the managers are given and suggestions are offered for future research building on the findings of this study.
