Mobile device forensics: A snapshot

Christopher Tassone, Ben Martini, Kim-Kwang Raymond Choo and Jill Slay Foreword | In the increasingly dynamic environment of mobile forensics, this paper provides an overview of the capabilities of three popular mobile forensic tools on three mobile phones based on Apple’s iOS, Google’s Android and RIM’s BlackBerry operating systems. The paper identifies where each specific tool is best applied and also describes the limitations of each in accessing contacts, call history, message data (SMS, MMS and emails), media files and other data. New releases of forensic tools and mobile operating systems may change the way the data are acquired and preserved in the future. It is therefore hoped that future research will continue to provide the digital forensics community with the most up-to-date overview of mobile forensics capabilities.
Decrease in insulin resistance has a key role in improvement of metabolic profile during intragastric balloon treatment

To the Editor, Obesity is a chronic polygenic disease in most cases [1]. Despite the different pathogenesis, all obese individuals have something in common: low growth hormone (GH) levels and increased insulin levels [2]. This hormonal imbalance plays an important role in other metabolic disorders, such as glucose intolerance and dyslipidemia. Adipose tissue mass is also important factor. It is an endocrine organ that secrets several metabolic hormones and proinflammatory cytokines. The intensity of their secretion positively correlates with adipose tissue mass [3]. Weight loss improves metabolic profile, although the exact mechanism is poorly understood. A detailed study regarding this matter was published only 1 year ago. The authors disclosed that diet-induced weight loss increases GH and ghrelin levels and decreases insulin and leptin levels [2]. However, neither one study analyzed parallel changes in metabolic hormones and metabolic profile in short time intervals during weight loss. Hence, the exact causative relations between these hormones are unknown. BioEnterics intragastric balloon (BIB) is a endoscopic method in obesity treatment. The balloon placed in the stomach delays stomach emptying and enhances the feeling of satiety [4]. We aimed to investigate changes in serum insulin, C-peptide, GH, blood glucose, glycated hemoglobin, insulin resistance and lipid profile in first, third and sixth month after BIB placement. Since our previous study showed that the change in ghrelin and leptin levels during BIB treatment considerably depends on body mass index (BMI) [5], we analyzed those changes separately in obese (BMI \40 kg/m) and morbid obese (BMI \40 kg/m) patients.
Authorship Attribution in Arabic using a hybrid of evolutionary search and linear discriminant analysis

Authorship Attribution is the problem of determining the authorship of one or more texts. Applications include disputed authorship, or deciding which of a collection of pieces of text were by the same author. A popular and successful approach is to characterize a specific author in terms of the usage pattern of function words. These are common words that are unrelated to subject matter, and tend to be used in specific ways by different authors. In English, a well-known collection of 70 function words is often used for this purpose. Previously, using a hybrid of evolutionary search and linear-discriminant analysis (LDA), we have shown excellent performance in authorship attribution in English based on a function word approach. Here, for the first time, we propose and test a set of Arabic function words for use in Arabic authorship attribution. Tests indicate that the chosen collection forms an effective basis for authorship attribution in Arabic.
Organizational Factors to Support Knowledge Management and Innovation

Purpose – The purpose of this paper is to analyze how organizational factors such as cultural values, leadership and human resource (HR) practices influence knowledge exploration and exploitation practices and innovation via an empirical study. Design/methodology/approach – From the knowledge-based view of the firm, six hypotheses were established and statistically tested in a sample of 111 Spanish companies belonging to innovative industries. Survey methodology was used with the aim of gathering data regarding knowledge management (KM) practices and certain, related organizational aspects in firms. Findings – This paper provides evidence of a moderating effect of knowledge-centered culture, knowledge-oriented leadership and knowledge-centered HR practices in the relationship between knowledge exploration and exploitation practices and innovation outcomes of companies. In line with previous literature, it is suggested that although KM practices are important on their own for innovation purposes, when certain enablers – organizational factors to overcome human barriers to KM – are properly established, the innovation capacity of the firm can be more successfully exploited. Research limitations/implications – The research is limited to high rate innovation industries. Future studies will include other industries and a more diverse sample of firms. Practical implications – The results of this study suggest that managers should place attention on knowledge exploration and exploitation practices along with several organizational enablers in order to achieve high levels of innovation results for the company. Originality/value – This paper provides new empirical evidence on the relationships between KM, organizational elements such as culture, leadership, HR practices, and innovation in a large sample of firms. To date, the empirical research of these relations has been mainly limited to descriptive case studies and there is thus a lack of empirical evidence with large samples of firms.
Quality versus quantity: acquisition of coping skills following computerized cognitive-behavioral therapy for substance use disorders.

AIMS
To evaluate the changes over time in quality and quantity of coping skills acquired following cognitive behavioral therapy (CBT), and examine potential mediating effects on substance use outcomes.


DESIGN
A randomized controlled trial (RCT) evaluating the effectiveness of a computerized version of CBT (CBT4CBT) as an adjunct to standard out-patient treatment over an 8-week period.


SETTING
Data were collected from individuals seeking treatment for substance dependence in an out-patient community setting.


PARTICIPANTS
Fifty-two substance abusing individuals (50% African American), with an average age of 42 years, and a majority reporting cocaine as their primary drug of choice.


MEASUREMENTS
Participants' responses to behavioral role-plays of situations associated with high risk for drug and alcohol use were audio-taped and rated independently to assess their coping responses.


FINDINGS
There were statistically significant increases in mean ratings of the quality of participants' coping responses for those assigned to CBT4CBT compared to treatment as usual, and these differences remained significant 3 months after treatment completion. Moreover, quality of coping responses mediated the effect of treatment on participants' duration of abstinence during the follow-up period.


CONCLUSIONS
These findings suggest that assignment to the computerized CBT program improved participants' coping skills, as measured by independent ratings of a role-playing task. It is also the first study to test and support quality of coping skills acquired as a mediator of the effect of CBT for substance use.
Single Index and Portfolio Models for Forecasting Value-at-Risk Thresholds *

The variance of a portfolio can be forecasted using a single index model or the covariance matrix of the portfolio. Using univariate and multivariate conditional volatility models, this paper evaluates the performance of the single index and portfolio models in forecasting Value-at-Risk (VaR) thresholds of a portfolio. The LR tests of unconditional coverage, independence and conditional coverage of the VaR forecasts suggest that the single index model leads to excessive and often serially dependent violations, while the portfolio model leads to too few violations. The single index model also leads to lower daily Basel Accord capital charges. The univariate models which display correct conditional coverage lead to higher capital charges than models which lead to too many violations. Overall, the Basel Accord penalties may be too lenient and favour models with too many violations.
Replacement of Dietary Fish Oils by Alpha-Linolenic Acid-Rich Oils Lowers Omega 3 Content in Tilapia Flesh

A 20-week feeding trial was conducted to determine whether increasing linolenic acid (18:3n-3) in vegetable oil (VO) based diets would lead to increased tissue deposition of 22:6n-3 in Nile tilapia (Oreochromis niloticus). Five isonitrogenous and isoenergetic diets were supplemented with 3% of either linseed oil (LO), a mixture of linseed oil with refined palm olein oil (PO) (LO–PO 2:1) and a mixture of refined palm olein oil with linseed oil (PO–LO 3:2) or with fish oil (FO) or corn oil (CO) as controls. The PO–LO, LO–PO and LO diets supplied a similar amount of 18:2n-6 (0.5% of diet by dry weight) and 0.5, 0.7 and 1.1% of 18:3n-3, respectively. Increased dietary 18:3n-3 caused commensurate increases in longer-chain n-3 PUFA and decreases in longer-chain n-6 PUFA in the muscle lipids of tilapia. However, the biosynthetic activities of fish fed the LO-based diets were not sufficient to raise the tissue concentrations of 20:5n-3, 22:5n-3 and 22:6n-3 to those of fish fed FO. The study suggests that tilapia (O. niloticus) has a limited capacity to synthesise 20:5n-3 and 22:6n-3 from dietary 18:3n-3. The replacement of FO in the diet of farmed tilapia with vegetable oils could therefore lower tissue concentrations of 20:5n-3 and 22:6n-3, and consequently produce an aquaculture product of lower lipid nutritional value for the consumer.
Painful prosthesis: approaching the patient with persistent pain following total hip and knee arthroplasty.

BACKGROUND
Symptomatic severe osteoarthritis and hip osteoporotic fractures are the main conditions requiring total hip arthroplasty (THA), whereas total knee arthroplasty (TKA) is mainly performed for pain, disability or deformity due to osteoarthritis. After surgery, some patients suffer from "painful prosthesis", which currently represents a clinical problem.


METHODS
A systematic review of scientific literature has been performed. A panel of experts has examined the issue of persistent pain following total hip or knee arthroplasty, in order to characterize etiopathological mechanisms and define how to cope with this condition.


RESULTS
Four major categories (non infective, septic, other and idiopathic causes) have been identified as possible origin of persistent pain after total joint arthroplasty (TJA). Time to surgery, pain level and function impairment before surgical intervention, mechanical stress following prosthesis implant, osseointegration deficiency, and post-traumatic or allergic inflammatory response are all factors playing an important role in causing persistent pain after joint arthroplasty. Diagnosis of persistent pain should be made in case of post-operative pain (self-reported as VAS ≥3) persisting for at least 4 months after surgery, or new onset of pain (VAS ≥3) after the first 4 months, lasting ≥2 months. Acute pain reported as VAS score ≥7 in patients who underwent TJA should be always immediately investigated.


CONCLUSIONS
The cause of pain needs always to be indentified and removed whenever possible. Implant revision is indicated only when septic or aseptic loosening is diagnosed. Current evidence has shown that peri-and/or post-operative administration of bisphosphonates may have a role in pain management and periprosthetic bone loss prevention.
Exercise in Computer Vision A Comparison of Thresholding Methods – NTNU –

This paper contains a comparison of common, simple thresholding methods. Basic thresholding, two-band thresholding, optimal thresholding (Calvard Riddler), adaptive thresholding, and p-tile thresholding is compared. The different thresholding methods has been implemented in the programming language c, using the image analysis library Xite. The program sources should accompany this paper. 1 Methods of thresholding Basic thresholding. Basic thresholding is done by visiting each pixel site in the image, and set the pixel to maximum value if its value is above or equal to a given threshold value and to the minimum value if the threshold value is below the pixels value. Basic thresholding is often used as a step in other thresholding algorithms. Implemented by the function threshold in thresholding.h Band thresholding. Band thresholding is similar to basic thresholding, but has two threshold values, and set the pixel site to maximum value if the pixels intensity value is between or at the threshold values, else it it set to minimum. Implemented by the function bandthresholding2 in thresholding.h P-tile thresholding. P-tile is a method for choosing the threshold value to input to the “basic thresholding” algorithm. P-tile means “Percentile”, and the threshold is chosen to be the intensity value where the cumulative sum of pixel intensities is closest to the percentile. Implemented by the function ptileThreshold in thresholding.h Optimal thresholding. Optimal thresholding selects a threshold value that is statistically optimal, based on the contents of the image.

Movement Assessment Battery for Children - second edition: Cross-cultural comparison between 11-15 year old children from the Czech Republic and the United Kingdom

BACKGROUND: With the exception of specifi c clinical methods, no widely used diagnostic tool for motor development assessment of children exists in the Czech Republic. The Movement Assessment Battery for Children – second edition (MABC-2) seems to be one the most developed instruments for childrenʼs motor coordination assessment. However, to use it in the Czech population of children in educational and psychological practice including physical education, the cross-validity of the test battery needs to be examined. OBJECTIVE: The aim of the study was to make a comparative analysis of performance in motor tasks of the MABC-2 measured in a Czech sample of 11–15 year old children and the United Kingdom (UK) normative sample from which the norms of the MABC-2 were established. METHODS: The Czech sample of 11–15 year old children (total n = 589; 310 boys, 279 girls) formed from a random selection of schools from all the geographical regions of the Czech Republic and all size categories of municipalities, was tested by the MABC-2. The results were compared to the performance of the UK normative sample of the same age (n = 344) reported in the MABC-2 Examinerʼs Manual by Henderson et al. (2007). For this comparative analysis, the eff ects size coeffi cient (d) and the z-test were used. RESULTS: From three manual dexterity tests of the MABC-2, mean performance of the Czech sample in the Drawing trail test was shown to be signifi cantly higher than the mean performance of the UK sample in all the age groups of both genders (d = 0.68–1.32; p < 0.01). On the other hand, the Czech sample demonstrated no signifi cant diff erences of performance in the gross motor coordination tests as compared to the performance of the UK sample. Regarding balance assessment, performance in the Two-board balance test (static balance) was found to be signifi cantly higher in almost all the age groups of Czech girls (d = 0.52–0.70, p < 0.01), while Czech boys showed a signifi cantly higher performance only in the Zig-zag hopping test (dynamic balance) at the ages of 14 and 15 years, as compared to the UK sample. In 1.9% of boys and 0.7% of girls in the Czech sample signifi cant motor diffi culties were identifi ed (total test score ≤5 percentile). CONCLUSIONS: The study revealed that the MABC-2 is valid only for assessment of gross motor coordination in Czech children, but not for assessment of manual dexterity and balance. Before the use of this test battery for Czech children for both practical and research purposes, an adjustment of the norms is needed for the Drawing trail test, Two-board balance test and Zig-zag hopping test.
Customized Feedback to Patients and Providers Failed to Improve Safety or Quality of Diabetes Care

OBJECTIVE
To assess whether providing customized clinical information to patients and physicians improves safety or quality of diabetes care.


RESEARCH DESIGN AND METHODS
Study subjects included 123 primary care physicians and 3,703 eligible adult diabetic patients with elevated A1C or LDL cholesterol, who were randomly assigned to receive customized feedback of clinical information as follows: 1) patient only, 2) physician only, 3) both the patient and physician, or 4) neither patient nor physician. In the intervention groups, patients received customized mailed information or physicians received printed, prioritized lists of patients with recommended clinical actions and performance feedback. Hierarchical models were used to accommodate group random assignment.


RESULTS
Study interventions did not improve A1C test ordering (P = 0.35) and negatively affected LDL cholesterol test ordering (P < 0.001) in the 12 months postintervention. Interventions had no effect on LDL cholesterol values (P = 0.64), which improved in all groups over time. Interventions had a borderline unfavorable effect on A1C values among those with baseline A1C >or=7% (P = 0.10) and an unfavorable effect on A1C values among those with baseline A1C >or=8% (P < 0.01). Interventions did not reduce risky prescribing events or increase treatment intensification. Time to next visit was longer in all intervention groups compared with that for the control group (P < 0.05).


CONCLUSIONS
Providing customized decision support to physicians and/or patients did not improve quality or safety of diabetes care and worsened A1C control in patients with baseline A1C >or=8%. Future researchers should consider providing point-of-care decision support with redesign of office systems and/or incentives to increase appropriate actions in response to decision-support information.
Taming the Flow Table Overflow in OpenFlow Switch

SDN has become the wide area network technology, which the academic and industry most concerned about.The limited table sizes of today’s SDN switches has turned to the most prominent short planks in the network design implementation. TCAM based flow table can provide an excellent matching performance while it really costs much. Even the flow table overflow cannot be prevented by a fixed-capacity flow table. In this paper, we design FTS(Flow Table Sharing) mechanism that can improve the performance disaster caused by overflow. We demonstrate that FTS reduces both control messages quantity and RTT time by two orders of magnitude compared to current state-of-the-art OpenFlow table-miss handler.
