A review towards developing a moment of information overload model

Information overload may affects everyone who receives, processes and presents the information. When individual is over supplied with the information which is more than he/she can process, it leads to information overload. In dealing with this phenomenon, individuals sometimes do not realize they are overloaded until the symptoms appear. Hence, it is important to recognize the starting point at where information overload had occurred. Several scholars have analyzed this phenomenon and investigated its causes, symptoms, effects and countermeasures of information overload but there are lacking information on moment of information overload which is it can be the starting point at where information overload had occurred. Therefore, the primary purpose of this research is to investigate the moment of information overload. In order to address a research question, researcher's approach to tackle research issue related to information overload is to merge knowledge from the literature by using thematic analysis. This paper provides an overview of the moment of information overload and how it is important to be recognized.
Surgical Success of Intraoral Autogenous Block Onlay Bone Grafting for Alveolar Ridge Augmentation

This article evaluates the surgical success of alveolar bone augmentation using intraoral block bone graft prior to dental implantation and measures the amount of bone accumulation using this technique. A consecutive retrospective study was conducted on patients who had onlay bone grafts from 1999 to 2001. Files of 56 healthy patients reporting 64 bone graft operations were reviewed. Medical history, smoking status, area of surgery, bone origin (donor sites) and complications were recorded. Panoramic and tomographic radiographs were measured for the vertical and horizontal bone addition and mesiodistal dimension of the graft. Graft exposure or/and graft removal were defined as failure; hematoma, swelling, inflammation, or temporary paresthesia were defined as complications. The average vertical addition was 5.6 mm measured from the bottom of the vertical lesion before bone grafting tothe top of the graft. The average faciolingual addition was 3.8 mm. The mesiodistal graft length ranged from 4 mm to 67 mm (average 15.2 mm). According to our criteria, 56 (87.5%) of the 64 bone grafts were successful, 46 (71.9%) were totally uneventful, and 10 (15.6%) had complications. Smoking and diabetes were associated with a high rate of complications and graft failure. More complications were observed in the vertical than in the horizontal bone grafts. Intraoral bone block graft is a predictable operation with high success rates that provides faciolingual and vertical bone addition. Onlay bone grafting has a low rate of complications and failures. Intraoral bone graft should not be recommended for diabetic patients and smokers.
The Free Breakfast Effect

This article presents the first evidence of the zero price effect in tourism. The multicomponent nature of tourism products adds complexity to the price-setting process, but also allows managers to take advantage of the interrelationships among the different components to maximize sales. Taking the zero price model, the authors adapt and apply it to a two-component tourism product. The experiments conducted show evidence in favor of the free breakfast effect: even though people lean toward their preferred, more expensive alternative, when the cheaper option offers a free breakfast, the demand for the latter increases and for the former it decreases. This result shows that the zero price effect is not confined to single products but also applies in multicomponent contexts. Important managerial implications in the realm of sales promotion policies are drawn.
A Lightweight Privacy-Preserving OAuth2-Based Protocol for Smart City Mobile Apps

In the forthcoming Smart City scenario, users' mobile applications will be of fundamental role towards supporting the envisioned functionalities and services. Mobile users, provided with a smartphone, will be capable of ubiquitously connecting to service providers through their installed mobile applications. However, this connection must be authenticated, which threatens the citizen privacy rights. Privacy-preserving mechanisms have already been proposed in the past; nevertheless, they are based on RSA groups or groups with bilinear pairings, which are inefficient in mobile devices due to its computational complexity. Thus, in this paper, we integrate a lightweight anonymous credential mechanism, suitable for computationally-limited mobile devices, into the user authentication phase of the OAuth2 protocol, which has become a de facto solution for user authentication in mobile applications. The proposed protocol enables citizen's authentication towards service providers, while preserving their privacy. Additionally, the protocol is compliant with the OAuth2 specification, which enables an easy integration in current mobile application implementations.
Markowitz principles for multi-period portfolio selection problems with moments of any order

The multi-period portfolio selection problem is formulated as a Markowitz mean–variance optimization problem in terms of time-varying means, covariances and higher-order and intertemporal moments of the asset prices. The crux lies in expressing the number of shares of any particular asset to be transacted on any future trading date, which is a non-anticipative process, as a polynomial of the changes in the discounted prices of all the risky assets. This results in the expected return of the portfolio being dependent on not only the means of the asset prices, but also the higher-order and intertemporal moments, and its variance being dependent on not only the second-order moments, but also the higher-order and intertemporal moments. As illustrations, we study the portfolio selection problems including the discrete version of the Merton problem. It is shown numerically that the efficient frontier obtained from Markowitz's discrete multi-period formulation coincides with that from Merton's continuous-time formulation when the number of rebalancing periods is ‘large’. The effects of dynamic trading, in particular volatility pumping, in comparison with a static single-period model are measured by a non-dimensional number, Dyn(P) (P, number of trading periods), which quantifies the relative gain due to dynamic trading. It is sufficient to rebalance the portfolio a few times in order to get more than 95% of the gain due to continuous trading.
Production and Efficiency in Association Football

Despite their proliferation, sporting production function studies remain almost entirely U.S.-based, concentrating largely (although not exclusively) on baseball. Mainly due to a dearth of match-play statistics, there have been few studies of other, more interactive sports. This study attempts to partly fill the gap by using a new data source containing information on specific match-play variables to estimate a season-based production function for English Premiership association football teams. On the basis of computed residuals, the authors also identify those teams shown to be relatively efficient and inefficient in various aspects of match plays.
An evaluation of total quality management activities in Korean companies

The objective of this study is to evaluate the current aspects of quality activities of Korean companies since total quality management (TQM) was introduced, to recognize the present problems and to suggest the future direction for TQM in Korea. The Malcolm Baldrige Quality Award Criteria were partially used as the evaluation criteria for this study. The result of this study is summarized as follows. Small and medium-sized companies were especially poor in human resource management. Further, large companies have to be improved in several criteria in comparison to the successful companies in the world. Finally, some guidelines for the successful implementation of TQM are suggested.
The New Politics of Global Reserve Reform

This is not the first moment during the last half century when debates about a global reserve asset have assumed a prominent place on the international public policy agenda. Discussions of global reserve reform were extensive in the lead up to the creation of the SDR in 1969 and soon afterwards, and then again during the late 1970s. In these earlier episodes, political interest in global reserve reform was relatively short-lived, responding to temporary instability in the global monetary system. This article argues that political interest this time around is likely to be more long-lasting because it reflects three distinct structural concerns about the existing reserve system simultaneously, each of which is likely to continue to attract political attention in the coming years. These concerns relate to reserve growth, reserve switching and equity issues. The fact that these concerns are not likely to disappear soon does not guarantee that significant global reserve reform will take place, but it should provide advocates with more time to press their case.
Denture Wearing during Sleep Doubles the Risk of Pneumonia in the Very Elderly

Poor oral health and hygiene are increasingly recognized as major risk factors for pneumonia among the elderly. To identify modifiable oral health–related risk factors, we prospectively investigated associations between a constellation of oral health behaviors and incident pneumonia in the community-living very elderly (i.e., 85 years of age or older). At baseline, 524 randomly selected seniors (228 men and 296 women; mean age, 87.8 years) were examined for oral health status and oral hygiene behaviors as well as medical assessment, including blood chemistry analysis, and followed up annually until first hospitalization for or death from pneumonia. During a 3-year follow-up period, 48 events associated with pneumonia (20 deaths and 28 acute hospitalizations) were identified. Among 453 denture wearers, 186 (40.8%) who wore their dentures during sleep were at higher risk for pneumonia than those who removed their dentures at night (log rank P = 0.021). In a multivariate Cox model, both perceived swallowing difficulties and overnight denture wearing were independently associated with an approximately 2.3-fold higher risk of the incidence of pneumonia (for perceived swallowing difficulties, hazard ratio [HR], 2.31; and 95% confidence interval [CI], 1.11–4.82; and for denture wearing during sleep, HR, 2.38; and 95% CI, 1.25–4.56), which was comparable with the HR attributable to cognitive impairment (HR, 2.15; 95% CI, 1.06–4.34), history of stroke (HR, 2.46; 95% CI, 1.13–5.35), and respiratory disease (HR, 2.25; 95% CI, 1.20–4.23). In addition, those who wore dentures during sleep were more likely to have tongue and denture plaque, gum inflammation, positive culture for Candida albicans, and higher levels of circulating interleukin-6 as compared with their counterparts. This study provided empirical evidence that denture wearing during sleep is associated not only with oral inflammatory and microbial burden but also with incident pneumonia, suggesting potential implications of oral hygiene programs for pneumonia prevention in the community.
Evaluation of safety at work in a psychiatric setting: the "Workplace Safety Assessment".

OBJECTIVES Workplace violence is a common risk for mental health professionals, and psychiatrists often encounter it in a variety of settings. The aim of this study was to estimate the prevalence and features of violent episodes toward psychiatrists in various mental healthcare system settings. METHODS All psychiatrists from the Region of Puglia (Apulia) were contacted (N=285) via email and were administered an on-line standardized questionnaire. RESULTS The response rate by psychiatrists was 57%. The main types of violence revealed were "threats" and "verbal aggression" and, of particular importance, "stalking". Female psychiatrists seemed to be at a higher risk of becoming victims of workplace violence, especially as regards verbal abuse (OR: 2.7, 95% CI: 1.2-6.5, c2 6.7, p=0.0095) and reported more serious psychological consequences with need for rest after the episode of aggression. CONCLUSIONS Our data confirm that mental health workers, particularly psychiatrists, are healthcare professionals at high risk for workplace violence. Future implementation of preventive strategies with the aim of reducing aggressive episodes towards psychiatrists should be a high priority for managers and policy-makers operating in the Italian healthcare sector.
Semisupervised SAR Image Change Detection Using a Cluster-Neighborhood Kernel

Change detection can be performed in a supervised manner. However, supervised methods for synthetic aperture radar (SAR) image change detection may suffer from lack of training samples. Therefore, in this letter, a semisupervised support vector machine classifier based on a cluster-neighborhood (CN) kernel is proposed for SAR image change detection. In the proposed method, samples are categorized into two neighborhoods with kernel k-means clustering algorithm. In addition, a CN kernel is constructed based on the composite-ratio kernel using the neighborhood-based statistical features. When a few labeled samples are available, the proposed CN kernel explores the information of unlabeled samples to enhance its discriminative ability and enhance its robustness against speckles. Experimental results on real SAR image change detection demonstrate the effectiveness of the proposed method when a few labeled samples are available.
Drosophila Melanogaster Gender Classification Based on Fractal Dimension

Biometrics, previously used only in human identification, can help experts in the analysis of biological images. Flies of the genus Drosophila have become model organisms by almost global presence and short life cycle. Facial recognition techniques and geometric morphometry can be used in image processing for classification. The latter requires human interaction. This work details a methodology based on stationary wavelet transform, Canny filter and fractal dimension aimed to infer the gender of Drosophila melanogaster based on images of their wings. The combination of variation in the training and test samples and classification methods showed the proposed algorithm's accuracy rate, 90%, outperformed other methods. The proposed methodology proved efficient by using a reduced number of attributes and did not require human interaction for feature extraction (landmarks).
University versus Firm Knowledge Spillovers - a Comparison of Productivity Eects in Swedish Regions ¤

This paper uses a new Swedish dataset of 299 …rms, aimed at analysing within-regional spillover eects of …rms' and univeristies' research on the productivity of …rms for 1997. The regional unit of analysis is the labour- market region, a functional region de…ned based on commuting patterns. We believe this is a more appropriate region for analysis than those pre- viously used. Due to statistical problems, which may be the result of spatial autocorrelation, we …nd no evidence whatsoever of spillover eects of knowledge, but the results must be considered as preliminary.
How reengineering transforms organizations to satisfy customers

Reengineering is a radically new process of organizational change that many companies are using to renew their commitment to customer service. By focusing on making improvements in all dimensions of the service organization—the human dimension, the work process dimension, and the technological dimension—reengineering helps companies overcome the systemic work barriers that interfere with efforts to achieve higher levels of customer satisfaction. Though reengineering is a long and sometimes difficult process that requires strong leadership, extensive participation, and a three-phased approach, it often results in dramatic improvements in how the organization responds to customer needs and expectations. Following this introductory article on the reengineering process are case studies from three organizations—an insurance company, a bank, and a telephone company—that have achieved significant productivity and quality breakthroughs by reengineering their processes and various departments.
When it can be good to feel bad and bad to feel good: Exploring asymmetries in workplace emotional outcomes

Within the field of Management and Organizational Studies, we have noted a tendency for researchers to explore symmetrical relationships between so-called positive discrete emotions or emotion-infused concepts and positive outcomes, and negative emotions or emotion-infused concepts and negative outcomes, respectively. In this Special Issue, we seek to problematize this assumption (without aiming to entirely discard it) by creating space for researchers to study what we term asymmetrical relationships. In particular, we explore the topic of when it can be good to feel bad and bad to feel good. The articles presented in this forum demonstrate both theoretically and empirically that appreciating these asymmetrical relationships holds considerable promise for enhanced understanding of a range of management and organizational phenomena, ranging from leadership and followership to emotional labor and dirty work. These unique theoretical and empirical insights have important relevance for organizational practice.
Can rocuronium replace succinylcholine in a rapid‐sequence induction of anaesthesia?

THE USE OF succinylcholine is associated with the potential occurrence of serious complications such as cardiac brady-arrythmias and asystole as well as a number of other undesirable side effects most of which are associated with the depolarising effect of succinylcoline. In spite of these side effects, succinylcholine has so far been the drug of choice for endotracheal intubation when a rapid-sequence induction (RSI) is needed. The need for a rapid-acting non-depolarising neuromuscular blocking agent to replace succinylcholine for the RSI of anaesthesia has therefore been obvious for many years. The rapid onset of action of rocuronium – a new non-depolarising muscle relaxant of the aminosteroid family – suggests that this drug has the potential to fulfil this gap. A large number of studies have addressed the question of whether clinically acceptable intubation conditions are provided with rocuronium as fast as with succinylcholine. However, most of these studies have either not been based on a relevant sample size or the anaesthesia technique has been practised on elective cases, which does not allow us to extrapolate to an RSI anaesthesia. In this issue of the journal Andrews et al. (1) address the question of whether there are clinically relevant differences between rocuronium and succinylcholine in the incidence of acceptable intubation conditions after 60 s during an RSI of anaesthesia. The study thus focuses on the so far unanswered question: Is it safe to use rocuronium for RSI anaesthesia? Their study is based on a proper two-step multicentre trial design to detect in the first place a possible difference between intubation scores of two doses of rocuronium (0.6 mg kga1 and 1.0 mg kga1). In the second part of the study the number of patients included is adequate not to overlook a predefined difference of 10% between the clinically acceptable intubation scores of succinylcholine and those of the dose of rocuronium found to be superior in the first part of the study.
Effects of low concentrations of antibiotics on Escherichia coli adhesion

We have previously shown that subinhibitory concentrations of antibiotics may influence the adhesion of Escherichia coli SS142 to human epithelioid tissue culture cells. This report shows that these effects are not limited to E. coli SS142 or to our tissue culture system. Most of the 10 E. coli strains studied showed decreased adhesion to Intestine 407 tissue culture cells after growth in 25% of the minimum inhibitory concentration of streptomycin, tetracycline, trimethoprimsulfametrole, chloramphenicol, and clindamycin. Nalidixic acid at 25% of the minimum inhibitory concentration caused an increase of adhesion. The hemagglutinating activity of the five hemagglutinating strains and the adhesiveness of E. coli SS142 to human buccal cells were similarly affected by low concentrations of the above-mentioned antibiotics. We conclude that E. coli adhesion to human epithelioid tissue culture cells is a valid model of bacterial adhesion because of its high accuracy and reproducibility.
Corporate Governance in Greece: Developments and Policy Implications

Purpose – This paper provides a comprehensive overview of corporate governance (CG) developments in Greece and has two objectives: to enrich the debate in this area and to contribute to the increasing literature by presenting the main aspects of the Greek CG framework; and to place the current CG developments and trends in Greece within the international debate, especially in the light of the recent debate to improve and convergence CG in the EU.Design/methodology/approach – First, reviews the evolution of the CG debate in Greece and its implication at the EU level. Second, provides a short view of the institutional‐economic environment in Greece, as it influences corporate governance practices. Then analyzes the CG mechanisms in the light of the recent key reforms. Finally, summarizes the findings and proceeds with some critical points and recommendations.Findings – The general finding is that the development of regulatory reforms was mostly an endogenous process influenced mainly by the speculative even.
An assessment of environmental factors influencing acid tolerance and sensitivity in Escherichia coli, Salmonella spp. and other enterobacteria

Environmental factors such as temperature, pH and nutrient level affect enterobacterial acid sensitivity, as do the presence of phosphate and Na+ and the extent of aeration. The mechanisms governing these effects are partially understood and the involvement of phoE, fur and atp in acid tolerance, of phoE, envZ, tonB, (p)ppGpp and cAMP in salt‐induced acid sensitivity and of rpoS in stationary‐phase acid tolerance are of particular interest. It should be noted that surface attachment enhances acid resistance.
Standards or Curriculum? Policy Constructions of the What and How of Schooling

of these connect well-rehearsed curriculum concerns about how curriculum decisions are made, by whom, and in whose interests. Others point to the importance of political and professional action, including moving beyond critique. As Taubman asks, “if we reject the Core, then what is the alternative” for ensuring all students have “the essential knowledge and skills they need to live in a democracy? ” Through this collection we find a starting point for engaging with these concerns. Rather than attempting to provide a summative view of the many implications of the CCSS, these authors offer a diverse portrait of ideas—hopefully offering new theoretical lines of flight and posing provocative questions for how we, as educators and researchers, can make sense of the evolving national reform space.
