Deception tactics for network interdiction: A multiobjective approach

This article develops defender‐attacker network interdiction models with deception. Here, deception refers to a preemptive and intelligent use of concealed interdiction assets and decoys by the defender, in addition to transparent assets commonly employed in modeling defender‐attacker problems. These models can help security planners to locate a limited number of checkpoints and sensors of various types to, for example, detect the smuggling of illegal products. The problem is complex, in part, because the objective functions of the defender and the attacker are different, and because the latter (which represents the attacker's behavior) is difficult to predict by the defender. First, we use duality theory and a generalized network flow model to devise an equivalent mixed‐integer programming formulation, and develop its Benders decomposition. We extend this formulation with a multiobjective approach to account for several behaviors simultaneously. The computational effort to solve these models is considerable, as exemplified by our testing on a variety of cases for a medium‐sized, notional network. Published 2011 Wiley Periodicals, Inc.

Two component customer relationship management model for healthcare services

Purpose – To sustain competitive advantage, it is necessary to understand consumers and their psychological fears and deliver them a service solution which is best under existing conditions so as to ensure consumer loyalty and retention. This paper seeks to conceptualise and operationalise customer relationship management (CRM) through two component model (operational CRM (OCRM) and analytical CRM (ACRM)), particularly in the healthcare sector.Design/methodology/approach – The relationship between OCRM, based on three patient‐staff constructs (physicians, nurses and support staff) and ACRM based on four constructs (satisfaction, repatronization, recommendation and organizational performance) was analysed using confirmatory factor analysis (AMOS). The data for the model were collected from 306 indoor patients of three large public hospitals who have been associated with the hospital for at least five years.Findings – The model portraying service quality as an antecedent to OCRM is found to be acceptable wh.
Ascorbate in pharmacologic concentrations selectively generates ascorbate radical and hydrogen peroxide in extracellular fluid in vivo

Ascorbate (ascorbic acid, vitamin C), in pharmacologic concentrations easily achieved in humans by i.v. administration, selectively kills some cancer cells but not normal cells. We proposed that pharmacologic ascorbate is a prodrug for preferential steady-state formation of ascorbate radical (Asc•−) and H2O2 in the extracellular space compared with blood. Here we test this hypothesis in vivo. Rats were administered parenteral (i.v. or i.p.) or oral ascorbate in typical human pharmacologic doses (≈0.25–0.5 mg per gram of body weight). After i.v. injection, ascorbate baseline concentrations of 50–100 μM in blood and extracellular fluid increased to peaks of >8 mM. After i.p. injection, peaks approached 3 mM in both fluids. By gavage, the same doses produced ascorbate concentrations of <150 μM in both fluids. In blood, Asc•− concentrations measured by EPR were undetectable with oral administration and always <50 nM with parenteral administration, even when corresponding ascorbate concentrations were >8 mM. After parenteral dosing, Asc•− concentrations in extracellular fluid were 4- to 12-fold higher than those in blood, were as high as 250 nM, and were a function of ascorbate concentrations. By using the synthesized probe peroxyxanthone, H2O2 in extracellular fluid was detected only after parenteral administration of ascorbate and when Asc•− concentrations in extracellular fluid exceeded 100 nM. The data show that pharmacologic ascorbate is a prodrug for preferential steady-state formation of Asc•− and H2O2 in the extracellular space but not blood. These data provide a foundation for pursuing pharmacologic ascorbate as a prooxidant therapeutic agent in cancer and infections.
Fax Surveys: Return Patterns and Comparison with Mail Surveys

The authors investigate response patterns to fax surveys in comparison with mail surveys and explore the relative advantages and disadvantages of the two methods. The results of two studies show that the answers to questions sent by fax were comparable to those received by mail, but they were received more quickly and in greater numbers. For many types of surveys that otherwise would have used mail, using fax machines can yield higher returns at lower cost per returned questionnaire.
Fluid Replacement Strategy in Severe Acute Pancreatitis

Adequate fluid resuscitation, pain control and organ support represent the cornerstones of treatment for acute pancreatitis. In this review, following questions will be answered on the basis of recent literature data: 1.What is the adequate volume of fluid to be administered and when should it be administered? 2. What type of fluid should be utilized? 3. What are the contraindications of an excessive amount of fluid? The suggestion to the practicing physician is that the amount of fluid administered patients with acute pancreatitis should be in the range of 3.1-4.1 l during the initial 24 hours after admission. The fluids used should be the lactated Ringer’s solution because the pH is more balanced than simple saline solution. Caution should be recommended regarding early fluid administration; the fluid should be administered under continuous monitoring.
The classification and importance of E‐S‐Qual quality attributes: an evaluation of online shoppers

Purpose – The purpose of this study is to classify and assess the importance levels of the quality attributes of E‐S‐QUAL measurement scale, aiming to focus on the most important attributes to improve.Design/methodology/approach – E‐S‐QUAL measurement scale is classified according to Kano's model and the relative importance levels of the E‐S‐QUAL quality attributes are revealed via analytical hierarchy process (AHP). The data of the study were gathered through a questionnaire, which consisted of four parts and was applied to 202 online shoppers in Izmir/Turkey.Findings – Almost all of the quality attributes are placed under one‐dimensional category. Privacy dimension is found to be a high value‐added attribute, whereas the least important attributes are found to be within the efficiency dimension. None of the quality attributes of E‐S‐QUAL are regarded as attractive attributes.Practical implications – This study is expected to attract the attention of practitioners on the most important quality attributes.
Effects of a Population Bottleneck on Whooping Crane Mitochondrial DNA Variation

Abstract: The Whooping Crane (Grus americana) is an endangered bird that suffered a severe population bottleneck; only 14 adults survived in 1938. We assessed the genetic effect of this human‐caused bottleneck by sequencing 314 base pairs ( bp) of the mitochondrial DNA control region from cranes that lived before, during, and after this bottleneck. The maximum length of DNA amplifiable from museum specimens was negatively correlated with age, and only 10 of 153 specimens yielded the entire 314 bp sequence. Six haplotypes were present among the prebottleneck individuals sequenced, and only one of these persists in the modern population. The most common modern haplotype was in low frequency in the prebottleneck population, which demonstrates the powerful effect of genetic drift in changing allele frequencies in very small populations. By combining all available data, we show that no more than one‐third of the prebottleneck haplotypes survived the human‐caused population bottleneck. High levels of variation of substitution rates among nucleotide sites prevented us from estimating the prebottleneck population size. Our data will be incorporated into the captive breeding program to allow better management decisions regarding the preservation of current genetic diversity. These data offer the first glimpse into the genetic toll this species has paid for human activities.
The Linear Plasmid pDHL1 from Debaryomyces hansenii Encodes a Protein Highly Homologous to the pGKL1‐Plasmid DNA Polymerase

Both the linear plasmids, pDHL1 (8·4 kb) and pDHL2 (9·2 kb), of Debaryomyces hansenii TK require the presence of a third linear plasmid pDHL3 (15·0 kb) in the same host cell for their replication. A 3·5 kb Bam HI‐PstI fragment of pDHL1 strongly hybridized by Southern analysis to the 3·5 kb NcoI‐AccI fragment of pDHL2, suggesting the importance of this conserved region in the replication of the two smaller pDHL plasmids. The 4·2 kb pDHL1 fragment containing the above hybridized region was cloned and sequenced. The results showed that the cloned pDHL1 fragment encodes a protein of 1000 amino acid residues, having a strong similarity to the DNA polymerase coded for by ORF1 of the killer plasmid pGKL1 from Kluyveromyces lactis. The catalytic and proof‐reading exonuclease domains as well as terminal protein motif were well conserved as in DNA polymerases of pGKL1 and other yeast linear plasmids. Analysis of the cloned fragment further showed that pDHL1 encodes a protein partly similar to the α subunit of the K. lactis killer toxin, although killer activity was not known in the DHL system. Analysis of the 5′ non‐coding region of the two above pDHL1‐ORFs reveal the presence of the upstream conserved sequence similar to that found upstream of pGKL1‐ORFs. The possible hairpin loop structure was also found just in front of the ATG start codon of the pDHL1‐ORFs like pGKL1‐ORFs. Thus the cytoplasmic pDHL plasmids were suggested to possess a gene expression system comparable to that of K. lactis plasmids. © John Wiley & Sons, Ltd.
Towards a new model of "customer compliance" service provision

Purpose – In the last ten years, businesses taking advantage of market deregulation, call‐centre, intranet and internet technology have broken traditional marketing norms and path‐dependent customer management practices. These businesses offer substantially lower prices and good customer service. In spite of anecdotal evidence of the high level of service complaints in the press, these businesses are expanding rapidly by growing the market and by taking share from traditional suppliers. Service failure recovery and complaint management are two areas which are extensively re‐designed by such businesses. This paper aims to identify and examine such new practices. The authors suggest that the traditional “customer‐centricity” model is being replaced by a “customer‐compliance business model” (CCBM) of service provision. This new model and its propositions defy conventional thinking in the areas of service recovery and complaint management.Design/methodology/approach – Available data and research are reviewed,.
Distant object recognition with Grabcut for an active-zooming camera

In this paper a method for distant object recognition is proposed. We propose an iterative structure for distant object recognition using an active-zooming camera like PTZ camera. We adopt Graphcut-based segmentation algorithm, Grabcut, to our structure in order to select candidate regions for zooming and gazing. Grabcut is utilized through the modified strategy for our purpose. And we also propose two failure detection methods based on contour points and homography for our object recognition system. We show that our candidate region selection method is available for distance change from the camera, and also validate our recognition method through the real experiment.
Franchisor use of influence and conflict in a business format franchise system

Purpose – This study aims to examine the relationship between a franchisor's use of different types of persuasive communication to influence its franchisees and franchisee perceptions of conflict in the franchise relationship.Design/methodology/approach – Multiple regression analysis of survey data collected from franchisees of a US‐based franchise system.Findings – Data analysis indicates that a franchisor's use of requests, threats, and legalistic pleas is positively related to conflict in the franchisor‐franchisee relationship. These relationships are not moderated by franchisee dependence. Franchisee dependence, does however, negatively moderate the relationship between the franchisor's use of recommendations and conflict. The franchisor's use of information exchange and promises and conflict are not related. The results suggest that business format franchisors should use information exchange and promises and restrain from using requests, threats, and legalistic pleas to influence their franchisees. R.
A case study on travel information from social network — Focus in Facebook and blogs in Malaysia

Due to the rapidly growing of social network media such as Facebook, Twitter and Blog, the rich contexts and sharing information of human activities are also explosive increase. Lately, many people used social media as a platform to exchange and share information such as education, lifestyle, recipes and medical treatment. Tourism is one of the most popular topics shared in Facebook and Blog. To explore details about the travel data, we created a survey to study the users sharing behavior. This paper presents the case study of travel sharing information in social network and the travel data collection in Place of Interest (POI) in Malaysia.
A systematic approach for Failure Modes and Effects Analysis of System-On-Chips

This paper proposes a method to perform failure mode and effects analysis (FMEA) on system-on- chips (SoC). An automatic tool extracts information from the SoC description and uses them to estimate the intrinsic criticality of invariant and elementary "sensitive zones " and to compute metrics such failure rates, safe failures fraction and diagnostic coverage. A validation flow based on fault injection and fault simulation is included to cross check the FMEA.
Adherence to Cognitive Behavioral Therapy for Insomnia (CBTI) Among Women Following Primary Breast Cancer Treatment: A Pilot Study

Cognitive behavioral therapy for insomnia (CBTI) has proven efficacy, yet 32%–89% of patients fail to consistently follow recommendations. This pilot study examines adherence to CBTI in breast cancer survivors with insomnia. There was a significant decline in adherence to prescribed rise time, and total time in bed, but no change in adherence to prescribed bedtime during six weekly sessions. Factors associated with higher adherence included lower fatigue and higher baseline motivation. Higher adherence was associated with worse subjective sleep quality at the beginning of CBTI and fewer nocturnal awakenings at the end of treatment. Results provide preliminary evidence supporting the impact of adherence on sleep outcomes such as fewer nocturnal awakenings. Attention to adherence as part of CBTI may yield greater sleep improvements.
Antibacterial Activity of Silver-nanoparticles Against Staphylococcus aureus and Escherichia coli

The antibacterial activities of silver nanoparticles (Ag-NPs) were studied with respect to Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli by observing the bacterial cells treated or not with Ag-NPs by field emission scanning electron microscope (FE-SEM) as well as measuring the growth curves, formation of bactericidal reactive oxygen species (ROS), protein leakage, and lactate dehydrogenase activity involved in the respiratory chain. Bacterial cells were treated with Ag-NPs powder, and the growth rates were investigated under varying concentrations of Ag-NPs, incubation times, incubation temperatures, and pHs. As a result, S. aureus and E. coli were shown to be substantially inhibited by Ag-NPs, and the antibacterial activity of Ag-NPs did not fluctuate with temperature or pH. These results suggest that Ag-NPs could be used as an effective antibacterial material.
A Policy-Based Framework for Managing Information Security and Privacy Risks in BYOD Environments

In a world where consumerisation of IT has driven individuals to acquire and use the latest technologies, an influx of employee personally owned devices has populated corporate environments. This phenomenon is known as Bring Your Own Device (BYOD). Managing organisational information resources has become increasingly complex with the concept of BYOD. Despite the perceived benefits of work flexibility, increased productivity, and efficiency of employees, BYOD raises many concerns relating to information security and privacy that can lead to confidential information loss. This prompts the demand for effective mobile device management tools, policies, standards and procedures. With most BYOD solutions failing to meet the requirement for holistic management of BYOD, this paper proposes a policy-based solution framework that organisations can adopt to achieve information security and privacy in BYOD environments.

Parenting Styles, Adolescent Substance Use, and Academic Achievement

This article investigates how children and their parents rate their parenting styles, and how this rating is associated with academic achievement, alcohol, and tobacco use. We surveyed students and their parents in two public school districts. A total of 386 matched parent-child pairs from eighth- and ninth-grade students were analyzed for parent and student classification of parents as authoritative, authoritarian, permissive, or mixed parenting styles. Agreement on parenting styles between parents and children was poor. Students perceived parents as less authoritative, less permissive and more authoritarian than parents considered themselves. High grades were associated with child and parent perception of higher authoritativeness, lower permissiveness, and lower authoritarianism. Child tobacco and alcohol use was associated with child perception of lower authoritativeness, and higher permissiveness while parent perception of parenting style was not associated with child substance use. This study provides further evidence that parenting styles and adolescents' perceptions of them are associated with child achievement and substance use. While we cannot determine whether child or parent perception of parenting style is more accurate, child perception is more strongly associated with grades and substance use than is parent perception. It is likely that parents would benefit from understanding how they are perceived by their children.
Topic word set-based text clustering

Clustering is the task of grouping related and similar data without any prior knowledge about the labels. In some real world applications, we face huge amounts of unstructured textual data with no organization. In these situations, clustering is a primitive operation that needs to be done to help future e-commerce tasks. Clustering can be used to enhance different e-commerce applications like re-commender systems, customer relationship management systems or personal assistant agents. In this paper we propose a new method for text clustering, by constructing a term correlation graph, and then extracting topic word sets from it and finally, categorizing each document to its related topic with the help of a classification algorithm like SVM. This method provides a natural and understandable description for clusters by their topic word sets, and it also enables us to decide the cluster of documents only when needed and in a parallel fashion, thus significantly reducing the offline processing time. Our clustering method also outperforms the well-known k-means clustering algorithm according to clustering quality measures.
Motor signs during the course of Alzheimer disease

Background: Motor signs (MOSIs) are common in Alzheimer disease (AD) and may be associated with rates of cognitive decline, mortality, and cost of care. Objective: To describe the progression and identify predictors of individual MOSIs in AD. Methods: A cohort of 474 patients with AD at early stages was followed semiannually for up to 13.1 years (mean 3.6 years) in five centers in Europe and the United States. MOSIs were rated using a standardized portion of the Unified Parkinson’s Disease Rating Scale. Overall, 3,030 visits/assessments of MOSIs (average 6.4/patient) were performed. Prevalence and incidence rates were calculated, and cumulative risk graphs were plotted for individual non-drug-induced MOSI domains. Rates of change over time taking into account potential covariates were also estimated. With use of each MOSI domain as outcome in Cox models, predictors of MOSI incidence were identified. Results: At least one MOSI was detected in 13% of patients at first examination and in 36% for the last evaluation. Total MOSI score increased at an annual rate of 3% of total possible score. Rates of annual change for speech/facial expression (4%), rigidity (2.45%), posture/gait (3.9%), and bradykinesia (3.75%) were of similar magnitude, and their occurrence increased from first (3 to 6%) to last (22 to 29%) evaluation. Tremor was less frequent throughout the course of the disease (4% at first and 7% at last evaluation) and worsened less (0.75% increase/year). Conclusions: Most motor signs occur frequently and progress rapidly in Alzheimer disease. Tremor is an exception in that it occurs less frequently and advances at slower rates.
Conservative Treatment for Mild Femoroacetabular Impingement

Purpose. To report early results of conservative treatments (including modifications in activities of daily living) for mild femoroacetabular impingement. Methods. 27 male and 10 female athletic patients aged 23 to 47 years presented with unilateral hip pain secondary to femoroacetabular impingement and an alpha angle of <60°. Patients were instructed to adapt to their safe range of movement and perform activities of daily living with minimal friction. The Harris Hip Score and non-arthritic hip score before and after treatment were compared. Open or arthroscopic hip surgery to remove the impinging bone was indicated when conservative treatment failed. Results. Patients were followed up for 25 to 28 months. Of the 37 patients, 4 underwent surgical treatment after conservative management failed. For the remaining 33 patients, the mean Harris Hip Score improved significantly from 72 before treatment to 91 at the 24-month follow-up. The mean non-arthritic hip scores improved from 72 to 91, and the mean visual analogue scores for hip pain from 6 to 2. Six of the 33 patients had recurrent hip pain and discomfort but not severe enough for surgical treatment. Conclusion. Conservative treatment did not improve the range of hip movement, despite improvement in function and symptoms. Yet it achieved good early results, as long as the patients could modify activities of daily living to adapt to their hip morphology.
