Testing a Typology of Mobile Phone Victimisation Using Cluster Analysis

Mobile victimisation is one form of cyberaggression that is increasing and affecting many young people today in the developing world. While studies on cyberbullying and cybervictimisation exist, the focus on mobile victimisation is limited. In addition, findings reported in earlier studies have been mainly from developed countries and inconclusive. There is also limited theoretical work to enhance conceptualisation and general understanding of mobile victimisation. Understanding this phenomenon in the developing countries is particularly critical as mobile phone usage and crime are among the highest in the world, legislation against misuse is not well developed and there is general lack of awareness of the national and international implications of cyberaggression in the developing nations. Through an extensive review of literature on victimisation, this paper develops a typology, i.e. Mobile Victimisation Typology (MVT), that caters to the understanding of mobile victimisation. The researchers also went further to validate empirically the MVT using cluster analysis. This confirmed all the three categories of victims proposed in the MVT and proved that it's three predictors could influence victims differently. The present findings are useful in creating awareness of mobile victimisation risks and can be used to inform the development of programmes, policies and legislation to control mobile bullying and victimisation in the developing nations in a more efficient and relevant direction in terms of resource and impact management.
Complementary Optimal Approaches for Survivable WDM Mesh Network Design: Transceiver Deployment and Traffic Engineering

An integer linear program model is presented for performing the most economical deployment of transceivers to enable network survivability. However, there is always room left for improvements in the traffic engineering protection scheme yielded. A complementary formulation then finds out how to also use protection resources elsewhere; substantially increasing the global network availability as a result. A study case shows that optimal traffic engineering can extend full link protection to 8 (out of 10) links over networks designed for 2 single failures.
An Active Resource Management Approach In Software Process

Existent artifacts and documents produced in software process are legacy problem solving resources. This paper tends to provide an efficient mechanism that covers different phases of software process and delivers these resources in an active way. It extends a semantic data model to be an active Resource Space and benefits forming a resource recommendation centric aided modeling environment for software process. An empirical case of the proposed approach is presented.
The Image of a Manager in Market Conditions

The purpose of this research is to determine the specificity of and prerequisites for the formation of an effective image of a manager in market conditions. The research used a set of theoretical and experimental methods: theoretical (analysis, generalization, systematization), empirical (observation of the peculiarities of managerial activity in modern organizations, presence or absence of a positive image of a manager in said organizations, with a view to determining the level of development of the motivational, cognitive, operative, and personal components of the readiness of modern organization managers for forming a positive image). The analysis of the “manager image” concept in the context of current trends in the development of management and social relations found that the peculiarity of the manager image in modern conditions is its close relation to the principle of continuous improvement of personal moral and professional qualities that are important in the modern business world. The constituents of the manager image were identified and characterized. It was found that the manager image emerges in the consciousness and subconscious of subordinates due to natural workplace and personal interaction with the manager. The fundamental factors in the formation of a positive modern manager image in transition economies should be professionalism and active communication between the manager and subordinates, company owners, and the general public, based on honesty and transparency, as well as flexibility, adaptability, versatility, and relevant knowledge in the field of management.
Compressive Channel Estimation in Space Domain for Massive MIMO Systems

In the existing compressive sensing (CS) theory, the accurate reconstruction of an unknown signal lies in the awareness of its sparsifying dictionary. For the estimation of channel parameters in massive multiple-input-multiple-output (MIMO) systems, however, it is impractical to set a fixed sparsifying Fourier dictionary prior due to the continuity of the angles of departure (AoD) for different wireless paths. To address this continuous optimization problem, the particle swarm optimization (PSO) algorithm was applied in this paper. Furthermore, combined with the orthogonal matching pursuit (OMP) algorithm based on the CS strategy, we develop a novel PSO-OMP channel estimation algorithm for massive MIMO system. Simulation results under different conditions demonstrate that the proposed method achieves much higher accuracy and yields superior performance in terms of bit-error-rate (BER).
The effect of mobile phone electromagnetic fields on the alpha rhythm of human electroencephalogram

Mobile phones (MP) emit low‐level electromagnetic fields that have been reported to affect neural function in humans; however, demonstrations of such effects have not been conclusive. The purpose of the present study was to test one of the strongest findings in the literature; that of increased “alpha” power in response to MP‐type radiation. Healthy participants (N = 120) were tested using a double‐blind counterbalanced crossover design, with each receiving a 30‐min Active and a 30‐min Sham Exposure 1 week apart, while electroencephalogram (EEG) data were recorded. Resting alpha power (8–12 Hz) was then derived as a function of time, for periods both during and following exposure. Non‐parametric analyses were employed as data could not be normalized. Previous reports of an overall alpha power enhancement during the MP exposure were confirmed (relative to Sham), with this effect larger at ipsilateral than contralateral sites over posterior regions. No overall change to alpha power was observed following exposure cessation; however, there was less alpha power contralateral to the exposure source during this period (relative to ipsilateral). Employing a strong methodology, the current findings support previous research that has reported an effect of MP exposure on EEG alpha power.

When Rivals Merge, Think Before You Follow Suit

The article argues that companies should think carefully before responding to a rival's merger activity by pursuing major acquisitions of their own. It is noted that such hastily-arranged deals are often not well-considered, can come at a steep price if a bidding war breaks out, and frequently involve less-than-optimal target firms. Several alternative strategies are discussed including strategic retreat from peripheral markets, focusing more on innovation and organic growth, and building a counterposition by means of multiple small acquisitions.

Infarct Patterns, Collaterals and Likely Causative Mechanisms of Stroke in Symptomatic Intracranial Atherosclerosis

Background: There are limited data on the specific mechanisms of stroke in patients with intracranial atherosclerotic stenosis (ICAS). We undertook this study to describe infarct patterns and likely mechanisms of stroke in a large cohort of patients with ICAS, and to evaluate the relationship of these infarct patterns to angiographic features (collaterals, stenosis location and stenosis severity). Methods: We evaluated infarct patterns in the territory of a stenotic intracranial artery on neuroimaging performed at baseline and during follow-up if a recurrent stroke occurred in patients enrolled in the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) trial. We defined the likely mechanism of stroke (artery-to-artery embolism, perforator occlusion, hypoperfusion or mixed) according to the site of ICAS and based on the infarct patterns on neuroimaging. Collaterals were assessed using American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grades, and stenosis severity using the WASID trial's measurement technique. We evaluated the association of infarct patterns with angiographic features using χ2 tests. Results: The likely mechanisms of stroke based on the infarct patterns at baseline in the 136 patients included in the study were artery-to-artery embolism (n = 69; 50.7%), perforator occlusion (n = 34; 25%), hypoperfusion (n = 12; 8.8%) and mixed (n = 21; 15.5%). Perforator-occlusive infarcts were more frequent in the posterior circulation, and mixed patterns were more prevalent in the anterior circulation (both p < 0.01). Most of the mixed patterns in the anterior circulation combined small pial or scattered multiple cortical infarcts with infarcts in border-zone regions, especially the cortical ones. Isolated border-zone infarcts were not significantly associated with a poor grading for collaterals or the severity of stenosis. Among 47 patients with a recurrent infarct during follow-up, the infarct patterns suggested an artery-to-artery embolic mechanism in 29 (61.7%). Conclusions: Artery-to-artery embolism is probably the most common mechanism of stroke in both the anterior and the posterior circulations in patients with ICAS. An extension of intracranial atherosclerosis at the site of stenosis into adjacent perforators also appears to be a common mechanism of stroke, particularly in the posterior circulation, whereas hypoperfusion as the sole mechanism is relatively uncommon. Further research is important to accurately establish the specific mechanisms of stroke in patients with ICAS, since preliminary data suggest that the underlying mechanism of stroke is an important determinant of prognosis.
Ensuring Security to Data on Cloud using Cryptography

As the information created by the ventures that should be put away and used (e.g. messages, individual wellbeing records, photograph collections, charge reports, budgetary exchanges and so on) is quickly expanding information proprietors are inspired to outsourced their nearby complex information administration frameworks into the cloud for its extraordinary adaptability and monetary reserve funds. Distributed storage permits shoppers and organizations to utilize the application without establishment and access their own records at any PC with web access. In distributed storage, the information will be put away given by cloud administration suppliers (CSPs). Cloud administration suppliers must have a reasonable approach to ensure their customers information. In any case, in information security assurance and information recovery control is most testing exploration work in distributed computing. This paper basically concentrates on center secured distributed storage administrations i.e by encrypting the information it can store the data in securely.
Attitude Determinants in Proposed Goods and Services Tax among Manufacturing Companies in Malaysia

Malaysian Government wanted to replace the Sales and Service Tax with Goods and Services Tax (GST). The government would only introduce once everyone understand and familiar with the tax. This study is aimed to identify the determinants of attitudes towards the proposed GST among managers of manufacturing companies in Malaysia. Four (4) variables were used to measure determinants of attitude comprising awareness, understanding, preparedness and probable area of difficulties. A survey was carried out to acquire the data from 1,500 managers of manufacturing companies throughout Malaysia via questionnaire. Only 210 responded where nine (9) questionnaires were unusable giving a 13.4% (201) response rate. Data were analyzed using descriptive statistics on the demographic variables and five (5) constructs. Test of reliability and validity were also done on the five (5) variables. All the items in the five (5) constructs have mean score of above 3.00. Both the cronbach alpha value and KMO value have more than 0.70 for all the five (5) constructs. The study has a compatibility matching of 41.8% variance (R square) and significant (P<0.00) which shows that the determinants in attitude towards the proposed GST can be explained by the four (4) variables; awareness, understanding, preparedness and probable area of difficulties variables. The findings also found that that the four (4) variables are significant and positively related to attitude towards the proposed GST. Thus this study provides important and valuable inputs for the Government to implement strategic plan to enhance GST knowledge among managers of manufacturing companies in Malaysia in so that GST can be introduced without obstacles.

The Role of Management Consultants in Long-Term ERP Customization Trajectories: A Case from the Italian Local Government

This chapter proposes an understanding of the role of management consultants in the implementation of Enterprise Resource Planning Systems in the Public Sector. The analysis is grounded on the case of an Italian Local Government in the course of 10 years. Each period corresponds to a different key client-consultant relationship and Public Sector situation. By using situational maps, the authors have highlighted the deeply contextual reflexivity between consultants and client organizations in configuring consultants’ advice over time. The purpose of the chapter is to replace “guru-istic” accounts with a more relational perspective that describes consultants as existing only in relation with their clients and the evolving Public Sector situation.
Incidence of displacement after nondisplaced distal radial fractures in adults.

BACKGROUND It is standard practice to closely monitor distal radial fractures treated nonoperatively to ensure that there is no fracture displacement. Patients are often asked to initially return weekly for radiographs. To our knowledge, nondisplaced distal radial fractures in adults have not been specifically evaluated to determine if this level of vigilance is required. If this subset of fractures is unlikely to displace, the cost, radiation exposure, and inconvenience of weekly office visits could be spared. METHODS Using our billing database, we identified 642 closed distal radial fractures among the patients who presented to our institution during the four-year period from the beginning of 2006 to the end of 2009. Radiographs of the injuries were reviewed to identify fractures for which radiographic measurements were within predefined radiographic norms. Only those fractures that were believed to be nondisplaced by all reviewers were classified as nondisplaced for the purposes of this study. Radiographic measurements were made at the time of injury and at the time of fracture union to evaluate for displacement over time. The total number of clinic visits and radiographs that were received were calculated from the longitudinal medical record for each patient. RESULTS Eighty-two fractures were identified as nondisplaced. None displaced or required operative intervention. The largest measured difference from injury to fracture union for radial inclination was 3.6° (average 0.8°); for radial height, 2.1 mm (average 0.5 mm); and for palmar tilt, 3.1° (average 1.0°). These numbers are all within the error of measurement. CONCLUSIONS Nondisplaced distal radial fractures in adults appear to be inherently stable, and it may be appropriate to treat this subset of distal radial fractures with cast immobilization (when swelling allows) and a single follow-up visit with radiographs to document union at the time of cast removal.

MRE11 promotes AKT phosphorylation in direct response to DNA double-strand breaks

AKT is hyper-activated in many human cancers and promotes proliferation and cancer cell survival in response to DNA damaging agents. Ionizing radiation (IR) produces DNA double strand breaks (DSB) and activates AKT, however a direct mechanism linking intra-nuclear DSB and AKT signaling is lacking. Here we demonstrate that AKT is phosphorylated following IR in benign and malignant cells and, using colony-forming assays and in vitro rejoining assays, show that AKT promotes non-homologous end joining-mediated DSB repair and cell survival following IR. Further studies revealed that pAKT-S473, but not pAKT-T308 or total AKT, accumulates in the vicinity of IR-induced DSB and co-localizes with γH2AX and ATM-pSer1981. Based on whole-cell IR, nuclear UV microbeam, and endonuclease-induced DSB studies, we observed that pAKT-S473 is up-regulated by a DSB-induced signaling cascade, and this is dependent on the DSB sensor protein, MRE11. MRE11-dependent pAKT-S473 did not require the MRE11 endonuclease domain. The histone ubiquitin ligase RNF168 is also required for DSB-induced pAKT-S473, and DSB-induced pAKT-S473 is independent of DNA-PKcs, PI3K, and ATR. These data demonstrate that DSB activate a signaling cascade that directly promotes a PI3K-independent pathway of AKT phosphorylation that is dependent on MRE11-ATM-RNF168 signaling. Thus, these data directly link the presence of DNA breaks to AKT-mediated cell survival and support AKT as a target for cancer therapy.

Applying Simulation to the Problem of Detecting Financial Fraud

The investigation of fraud in business has been a staple for the digital forensics practitioner since the introduction of computers in business. Much of this fraud takes place in the retail industry. When trying to stop losses from insider retail fraud, triage, i.e. the quick identification of sufficiently suspicious behaviour to warrant further investigation, is crucial, given the amount of normal, or insignificant behaviour. It has previously been demonstrated that simple statistical threshold classification is a very successful way to detect fraud~\cite{Lopez-Rojas2015}. However, in order to do triage successfully the thresholds have to be set correctly. Therefore, we present a method based on simulation to aid the user in accomplishing this, by simulating relevant fraud scenarios that are foreseeing as possible and expected, to calculate optimal threshold limits. This method gives the advantage over arbitrary thresholds that it reduces the amount of labour needed on false positives and gives additional information, such as the total cost of a specific modelled fraud behaviour, to set up a proper triage process. With our method we argue that we contribute to the allocation of resources for further investigations by optimizing the thresholds for triage and estimating the possible total cost of fraud. Using this method we manage to keep the losses below a desired percentage of sales, which the manager consider acceptable for keeping the business properly running.
Knowledge Trading in Supply Chain Partnerships: The Role of Trust and Relationship Commitment

Based on relational exchange theory and transaction cost theory, a conceptual model for the relationships among trust, relationship commitment, knowledge trading and cooperative performance is proposed and empirically tested using the data collected from 256 Chinese manufacturing enterprises in supply chain with the structural equation model. The results show that there are significant and positive impacts of trust on relationship commitment, explicit knowledge trading, tacit knowledge trading and cooperative performance. Although relationship commitment has significant and positive impacts on tacit knowledge trading and cooperative performance, it does not impact explicit knowledge trading significantly. Finally, it is also proved that knowledge trading has significant and positive impact on cooperative performance.
Focal adhesion kinase is involved in mechanosensing during fibroblast migration

Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase localized at focal adhesions and is believed to mediate adhesion-stimulated effects. Although ablation of FAK impairs cell movement, it is not clear whether FAK might be involved in the guidance of cell migration, a role consistent with its putative regulatory function. We have transfected FAK-null fibroblasts with FAK gene under the control of the tetracycline repression system. Cells were cultured on flexible polyacrylamide substrates for the detection of traction forces and the application of mechanical stimulation. Compared with control cells expressing wild-type FAK, FAK-null cells showed a decrease in migration speed and directional persistence. In addition, whereas FAK-expressing cells responded to exerted forces by reorienting their movements and forming prominent focal adhesions, FAK-null cells failed to show such responses. Furthermore, FAK-null cells showed impaired responses to decreases in substrate flexibility, which causes control cells to generate weaker traction forces and migrate away from soft substrates. Cells expressing Y397F FAK, which cannot be phosphorylated at a key tyrosine site, showed similar defects in migration pattern and force-induced reorientation as did FAK-null cells. However, other aspects of F397-FAK cells, including the responses to substrate flexibility and the amplification of focal adhesions upon mechanical stimulation, were similar to that of control cells. Our results suggest that FAK plays an important role in the response of migrating cells to mechanical input. In addition, phosphorylation at Tyr-397 is required for some, but not all, of the functions of FAK in cell migration.
Immunopathologic effect of antigen recognition

Intracellular and extracellular antigens differ considerably in their processing and presentation to T lymphocytes (19). Peptides derived from intracellular antigens are generally presented to CD8 + T cells by major histocompatibility complex (MHC) class I molecules, which are expressed on virtually all somatic cells, while peptides derived from extracellular antigens are presented to CD4 + T cells by MHC class II molecules normally expressed by specialized, antigen-presenting cells (APC) (8). Thus, class I molecules bind to peptides derived both from pathogens entering the cytosol and from endogenously synthesized proteins. In contrast, class II molecules usually bind peptides derived from exogenous proteins taken up by professional APCs (macrophages, dendritic cells) which internalize soluble proteins by pinocytosis or endocytosis mechanisms (25). From these observations, the concept of endogenous and exogenous pathways has been developed (9, 29).
