Information security is a major challenge for organizations due to the proliferation of digitization and constant connectivity. It is becoming widely accepted that raising an information security culture, meaning instilling security behaviour in people interacting with ICTs, is key to maintaining a healthy security posture. However the academic field of information security culture has been described as immature, lacks empirical validation, while the constituents of the concept as well as methods, tools, frameworks and metrics for fostering and evaluating it within organisations remain elusive. This paper, based on a critical analysis of relevant literature and practice, provides a research agenda of critical issues that need to be addressed so that users, from security’s weakest link, become an important actor for proactive information security. These issues include the need for proper and employable definitions of information security culture and the need to explore the existence of security subcultures, the need to develop frameworks, tools and metrics for guiding, evaluating and comparing security culture raising programs, the need to explore the interplay between organisational elements (including organisational structure, type and management practices) and security culture, the need to identify the impact of security culture in issues such as innovation adoption, the need to investigate the influence of national and organisational culture on security culture and so on.
Phonon localization in glasses.

A universal but unexplained characteristic of glasses is the temperature-independent region or plateau in the thermal conductivity for temperatures 1\char21{}30 K. Examination of low-temperature thermal conductivity data for a wide variety of glasses indicates that the mean free path of the average thermal phonon becomes less than the phonon wavelength at temperatures in the vicinity of the plateau. Comparison with similar data in aggregates suggests that Ioffe-Regel localization of the vibrational modes occurs for phonons whose wavelength and mean free path are on the order of a structural correlation length of the material. Typical correlation lengths in glasses determined by this argument are 20\char21{}50 A\r{}. The universal plateau in bulk glasses is therefore associated with phonon localization due to strong scattering from inhomogeneities on this length scale.

Hybrid Model: Permeance Network and 3-D Finite Element for Modeling Claw-Pole Synchronous Machines

Designing a claw-pole synchronous machine implies solving many 3-D nonlinear magnetostatic problems, which makes the computation (CPU) time very long. In our model, the mesh is refined to reach the desired level of precision on global quantities, such as torque. Since the airgap is very thin (around 0.3 mm for a 100 mm diameter) and a Newton Raphson algorithm requires several iterations to converge, CPU time may be too high. Nowadays, much research is ongoing to reduce the CPU time, while preserving an acceptable accuracy. One of the most efficient methods is permeance networks, but this method is not suitable for complex geometries. Our main contribution is to use a permeance network in the areas where flux lines are easy to guess and to solve a 3-D Finite Element Method (FEM) problem in complex geometry areas of the magnetic device: the claw poles and the air gap, for example. Moreover, current sources belong to the permeance network model, so that there are no current sources in the 3-D FEM problem. Then, a 3-D scalar magnetic potential formulation can be used easily. The two classical magnetostatic formulations [magnetic scalar potential formulation (<inline-formula> <tex-math notation="LaTeX">$U_{m}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$h_{s}$ </tex-math></inline-formula>) and vector potential formulation (<inline-formula> <tex-math notation="LaTeX">$a$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$j$ </tex-math></inline-formula>)] are presented in this paper. Then, the hybridization of 3-D FEM formulation and the permeance network is presented. Numerical results are compared with experimental measurements and good agreement is obtained while reducing the CPU time.
Effect of methanolic extract of Tetrapleura tetraptera (Schum and Thonn) Taub leaves on hyperglycemia and indices of diabetic complications in alloxan-induced diabetic rats.

OBJECTIVE To investigate the ameliorative role of Tetrapleura tetraptera (Schum and Thonn) Taub (T. tetraptera) leaf in hyperglycemia with associated conditions like oxidative stress, kidney damage and disorders in lipid metabolism. METHODS Five groups of five rats each intraperitoneally received the following treatment schedules for 7 d: untreated normal control, untreated alloxan-diabetic control, diabetic treated with glibenclamide, normal rats treated with extract (50 mg/kg) and diabetic rats treated with the extract. Evaluations were made for fasting blood sugar, body weight changes, malondialdehyde, aspartate aminotransferase, alanine aminotransferase, bilirubin, superoxide dismutase, catalase, lipid profile, packed cell volume, hemoglobin, urea and creatinine in all the rats. RESULTS Whereas the untreated diabetic rats showed a significant decrease (P<0.05) in packed cell volume, superoxide dismutase, catalase and high-density lipoprotein-cholesterol with a concomitant increase in the levels of malondialdehyde, fasting blood sugar, aspartate aminotransferase, alanine aminotransferase, bilirubin, urea and creatinine, administration of methanolic extract of T. tetraptera leaf or glibenclamide alleviated these altered parameters in the treated rats. CONCLUSIONS Methanolic extract of T. tetraptera leaves possesses a potent capacity for treatment of diabetes and the accompanying complications, including oxidative stress and hyperlipidemia.
Statistical Applications in Genetics and Molecular Biology Smoothing Gene Expression Data with Network Information Improves Consistency of Regulated Genes

Gene set analysis methods have become a widely used tool for including prior biological knowledge in the statistical analysis of gene expression data. Advantages of these methods include increased sensitivity, easier interpretation and more conformity in the results. However, gene set methods do not employ all the available information about gene relations. Genes are arranged in complex networks where the network distances contain detailed information about inter-gene dependencies. We propose a method that uses gene networks to smooth gene expression data with the aim of reducing the number of false positives and identify important subnetworks. Gene dependencies are extracted from the network topology and are used to smooth genewise test statistics. To find the optimal degree of smoothing, we propose using a criterion that considers the correlation between the network and the data. The network smoothing is shown to improve the ability to identify important genes in simulated data. Applied to a real data set, the smoothing accentuates parts of the network with a high density of differentially expressed genes.
A general transmission line model for conventional metallic nanowires and innovative carbon nano-interconnects

A general transmission line model is presented, able to describe a large class of nano-interconnects, made either by conventional metallic nanowires or by innovative carbon materials (carbon nanotubes or graphene nanoribbons). A common frame is presented here, which allows describing the electrodynamics of such nano-structures by means of a modified Boltzmann transport equation. This model leads to a non-local dispersive Ohm's law, which is then coupled to Maxwell equations, to obtain the transmission line model. The quantum effects arising in nano-interconnects are included in the per-unit-length parameters of the transmission line model, so allowing the embedding of nano-interconnects into standard circuit simulators. The propagation properties of interconnects made by nanowires, carbon nanotubes and graphene nanoribbons are studied and a performance comparison is given, referring to the typical arrangements foreseen for the technology nodes of some nanometers.
Regional Variation in Rivalry: Canadians Really are Friendlier

Abstract Spectator sports embody social group conflict, where consumers periodically interact with opposing fans, thereby providing outlets for negative brand affect in the form of acrimony toward rivals. To assess the regional nature of rivalry, this study compared 5,145 sports consumers across the four United States Census regions and Canada, including five professional leagues. Consistent with regional personality clustering, fans of Canadian teams harbor less acrimony toward rivals, and fans of teams in the Northeastern US generally exhibit the most acrimony. When developing events and promotional partnerships, sports marketers and sponsors should recognize regional differences in how consumers react to rivals.
Le rôle des routines dans la construction des capacités dynamiques : le cas d’une entreprise dans le secteur touristique

Nous mobilisons le concept de routine afin de saisir la récurrence du processus de construction des capacités dynamiques. Nous adoptons une démarche d’étude de cas au sein d’un tour-opérateur. Notre méthode qualitative permet d’identifier deux capacités dynamiques : la première est liée à la diversification des activités et la deuxième est liée au développement du réseau commercial. Nos résultats soulignent l’importance des routines existantes et nouvelles dans la construction des capacités dynamiques. Ils montrent également que le processus de construction - qui est différent en fonction de la nature émergente ou délibérée de l’opportunité - résulte de la routinisation d’une expérimentation réussie.
Preferred Leisure Activities and Reasons for Participation: A Comparison Study with Implications for Marketing Leisure Services

Leisure service providers are concerned with understanding their potential consumers better in order to offer and market recreational activities that will attract a greater market share. Recognizing the universality of human needs and motives, while acknowledging individual interests, can aid in the design and promotion of successful recreation and leisure programs. This study compared two different groups' preferred leisure activities and reasons for participation. The results contributed to development of a humanistic marketing strategy that is applicable to park and recreation agencies' efforts to enhance consumer satisfaction.
What is The Role of Land Value in The Urban Corridor?

The high movement causes traffic congestion and indicates high movement intensity along the corridor. The higher attraction of the land use will encourage the higher attraction of movement and economic values in the location. This attraction is also affected by the high mobility in the corridor supported by available transport infrastructure. Thus this causes land values become increase significantly. Land use along the corridor can be seen as commercial function because this activity is able to survive in the premium location. The purpose of this research is to identify the effect of land use change toward land values in the commercial corridor. This research used positivistic method with descriptive analysis. The result shows that the land values change in commercial use in the corridor has different pattern of land use change pattern according to physical condition and land use which causes highly economic attraction. The new commercial land is influenced by the distance to city centre or CBD (Central Business District). Land use and public facilities that have local and city scope services do not give the significant impact to land values change.
Epidemiologic assessment of the role of blood pressure in stroke. The Framingham study.

Control of hypertension, labile or fixed, systolic or diastolic, at any age, in either sex appears to be central to prevention of atherothrombotic brain infarction (ABI). Prospectively, hypertension proved the most common and potent precursor of ABI's. Its contribution was direct and could not be attributed to factors related both to stroke and hypertension. Asymptomatic, causal "hypertension" was associated with a risk of ABI about four times that of normotensives. The probability of occurrence of an ABI was predicted no better with both blood pressure measurements or the mean arterial pressure than with systolic alone. Since there was no diminishing impact of systolic pressure with advancing age, the concept that systolic elevations are, even in the aged, innocuous is premature. Comparing normotensives and hypertensives in each sex, women did not tolerate hypertension better than men.
Multiobjective cellular genetic algorithm with adaptive fuzzy fitness granulation

Computational complexity is a major challenge in evolutionary algorithms due to their need for repeated fitness function evaluations. In the context of multiobjective evolutionary algorithms, there are a few attentions to the computational complexity of this kind of algorithms. Here, we aim to reduce number of fitness function evaluations in multiobjective cellular genetic algorithms by the use of fitness granulation via an adaptive fuzzy similarity analysis. In the proposed algorithm, an individual's fitness is only computed if it has insufficient similarity to a queue of fuzzy granules whose fitness has already been computed. If an individual is sufficiently similar to a known fuzzy granule, then that granule's fitness is used instead as a crude estimate. Otherwise, that individual is added to the queue as a new fuzzy granule. The queue size as well as each granule's radius of influence is adaptive and will grow/shrink depending on the population fitness and the number of dissimilar granules. The proposed method is applied to a set of 6 test problems. In comparison with two well-known multiobjective evolutionary algorithms, NSGA-II, and MoCell, computational results show that the proposed method is competitive with these algorithms.
Modified TEI Index: A Promising Parameter in Essential Hypertension?

Purpose: Modified TEI index is pointed to be more effective in the evaluation of global cardiac functions compared to systolic and diastolic measurements alone. We planned to determine its applicability in hypertension and relation with left ventricular mass index (LVMI). Methods: We studied 48 patients with mild/moderate hypertension and normal coronary angiograms. In total 22 patients (12 men, 10 women, mean age: 55 ± 6) with normal LVMI were studied in group I, 26 patients (12 men, 14 women, mean age: 57 ± 7) with increased LVMI in group II, and 20 patients (10 men, 10 women, mean age: 53 ± 7) with normal blood pressure as a control group. Standard 2D, Doppler, and mitral annulus pulse wave tissue Doppler were used for all measurements. Modified TEI index was calculated as diastolic time interval measured from end of Am wave to origin of Em (a′) minus systolic Sm duration (b′) divided by b(a′−b′/b′). Results: Modified TEI index was significantly higher in both groups than normal group and in group II than in group I. (Control group: 0.33 ± 0.05, group I: 0.51 ± 0.17, group II: 0.68 ± 0.16, P< 0.0001). Conclusion: Modified TEI index, a marker of left ventricular systolic and diastolic functions, is impaired in hypertensives before hypertrophy develops and impairment is more prominent in hypertrophy. Therefore, (1) modified TEI index in hypertensives is a safe, feasible, and sensitive index for evaluation of global ventricular functions. (2) Evaluation of hypertensives with this index periodically may guide interventions directed toward saving systolic and diastolic functions. (3) Modified TEI index is gaining importance as a complementary parameter to standard Doppler or in cases where standard Doppler has its limitations.
Measurement of QT dispersion

In 1985, Mirvis1 reported on a significant spatial variation in QT intervals in normal individuals and patients with acute myocardial infarction. More recently, there has been an increasing interest in what has become known as QT dispersion, which is defined as the difference between the maximum and minimum QT interval of the 12 lead ECG.2 A number of publications has shown a relation between increased QT dispersion and death from a cardiac cause.3-5 Other studies have shown that QT dispersion can be reduced as a result of certain drug treatments.6 7 On the other hand, increased QT dispersion has been shown not to be associated with increased cardiac death in patients with idiopathic dilated cardiomyopathy.8 It has also been suggested that increased QT dispersion may be a marker of arrhythmia risk in patients with hypertrophic cardio- myopathy,9 long QT intervals,2 and sustained ventricular arrhythmias.10 All of these studies have involved relatively small numbers of patients and, with the exception of one report,3 sensitivity and specificity of criteria have not been considered. Even in this study,3 the receiver operator characteristic (ROC) curve assessing different cut off values for abnormal QT dispersion was essentially developed on the basis of a training set. A major question arises—is a single measurement of QT dispersion of any clinical utility despite the fact that trends in QT dispersion can be linked with adverse outcome or improvement? To know whether a single measurement is reliable enough to have any prognostic value requires an understanding of the accuracy of measuring QT dispersion. In this connection, the articles by Kors and van Herpen11 and Yi and colleagues12 in this issue are of relevance. They provide an interesting sequel to earlier studies on QT dispersion assessed by manual …
Agricultural work-related injuries among farmers in Hubei, People's Republic of China.

OBJECTIVES This population-based study evaluated patterns of and risk factors for, agricultural injuries among farmers in the People's Republic of China. METHODS A multistage sample of 1500 Chinese farmers was selected from 14 villages. Face-to-face interviews with 1358 farmers were conducted between July 1997 and September 1997 (response rate = 91%). Agricultural work-related injuries that occurred in the previous 24 months and the associated factors were evaluated. RESULTS A total of 33% of the farmers reported at least 1 work-related injury in the 24 months before the survey. Major external causes of the injuries were hand tools (50%), falls (26%), and heavy falling objects (10%). The statistically significant risk factors for injury were low family income, 1 to 6 school years of education, self-reported pesticide exposure, tension in relationships with neighbors, and stress in life. The most notable result was the relation between self-reported pesticide exposure and injury, with farmers with greater pesticide exposure at significantly greater risk for injury. CONCLUSIONS The results of this study indicated that injuries occurring among Chinese farmers may have unique patterns and potential risk factors.
Foreign Direct Investment (FDI), Economic Growth and Bank Performance in Ghana

Several studies have used different methodologies to establish the link between FDI and economic growth. This study extends literature of the impact of FDI on economic growth in Ghana to include the impact of FDI on performance of Commercial banks in Ghana. The study used secondary data of FDI and macroeconomic variables from the World Bank data on countries while extracting financing data from the annual report of commercial banks over a 10 year period. The correlation as well as the regression results shows that FDI inflows have a positive and significant effect on the profitability of commercial banks in Ghana. Also, the study revealed that FDI is positively associated and statistically significant with economic growth both in the short run and in the long run. The study recommends that a comprehensive study be done on the subject matter using specific FDI inflows to the banking sector and bank performance banks to understand the exact impact of FDI on economic growth. The study also calls for government to step up effort to encourage more FDI inflows into the country.
The lysis function of RNA bacteriophage Qbeta is mediated by the maturation (A2) protein.

Complete or partial cDNA sequences of the RNA bacteriophage Qbeta were cloned in plasmids under the control of the lambdaP(L) promoter to allow regulated expression in Escherichia coli harbouring the gene for the temperature‐sensitive lambdaCI857 repressor. Induction of the complete Qbeta sequence leads to a 100‐fold increase in phage production, accompanied by cell lysis. Induction of the 5′‐terminal sequence containing the intact maturation protein (A2) cistron also causes cell lysis. Alterations of the A2 cistron, leading to proteins either devoid of approximately 20% of the C‐terminal region or of six internal amino acids, abolish the lysis function. Expression of other cistrons in addition to the A2 cistron does not enhance host lysis. Thus, in Qbeta, the A2 protein, in addition to its functions as maturation protein, appears to trigger cell lysis. This contrasts with the situation in the distantly related group I RNA phages such as f2 and MS2 where a small lysis polypeptide is coded for by a region overlapping the end of the coat gene and the beginning of the replicase gene.
