Transformational Leadership and Information System Effectiveness

This study examined the positive impact of a specific leadership style (i.e., transformational leadership) on information systems (IS) effectiveness in organizations based upon a subordinate's perspective. Specifically, we investigated system users' psychological mechanisms that may mediate the relationship between transformational leadership and IS effectiveness (i.e., individual and organization impacts and IS satisfaction) via perceived organizational support (POS) and systems self-efficacy (SSE) of system users in organizations. In order to test a mediation model, Partial Least Squares were performed on a sample (N=251) embedded in 25 branches of a large multi-national bank in Korea. The results indicated that: (1) transformational leadership behaviors were positively related to individual and organizational IS impacts and individuals' IS satisfaction, and (2) both POS and SSE of the system users mediated between transformational leadership and IS effectiveness, indicating that system users working with a transformational leader achieve IS effectiveness by perceived organizational support and high levels of systems self-efficacy. Theoretical and practical implications of this study and future research directions were discussed.
RDF versus attributed graphs: The war for the best graph representation

In this work, methods are developed to overcome the inherent problems of network abstraction and analysis from multiple heterogeneous data sources. RDF and attributed graphs are two common choices for graph modeling. While both are very similar with respect to the type of information that can be represented, characteristics intrinsic to each representation affect the analysis performed over the resultant network abstractions. By selecting a dual graph representation approach and leveraging the strengths of both models, the semantic analysis performed over RDF graphs is combined with the topological analysis applied to attributed graphs, to produce a comprehensive foundation for network analysis that cannot be easily achieved, nor its value matched, by one representation independently.

Comparing cooccurrence probabilities and Markov random fields for texture analysis of SAR sea ice imagery

This paper compares the discrimination ability of two texture analysis methods: Markov random fields (MRFs) and gray-level cooccurrence probabilities (GLCPs). There exists limited published research comparing different texture methods, especially with regard to segmenting remotely sensed imagery. The role of window size in texture feature consistency and separability as well as the role in handling of multiple textures within a window are investigated. Necessary testing is performed on samples of synthetic (MRF generated), Brodatz, and synthetic aperture radar (SAR) sea ice imagery. GLCPs are demonstrated to have improved discrimination ability relative to MRFs with decreasing window size, which is important when performing image segmentation. On the other hand, GLCPs are more sensitive to texture boundary confusion than MRFs given their respective segmentation procedures.
Contour-based object detection in Automatic Sorting System for a parcel boxes

In the Automatic Sorting System, precision volume and size of the parcel boxes are all concerned. Different box size will certainly have a limited of personnel who visually identify and pick the objects. Computer vision are related to image processing and image analysis tend to focus on 2D image by pixel operation. Contour-based object detection is one alternative can measure the area for objects. In this paper will be in design automation development of a computer vision system that is able to get the volume of the parcel boxes. To get this this value if know the amount of length, width, and height. To find out the dimensional scale of parcel will be used two webcam cameras by calculating the pixels that are captured on camera and making comparison for calibration. The 2D image consists of two images from camera captured with vertical and horizontal view. After getting the length, width, and height of the parcel box, there will be a multiplication program is used to obtain the result of volume. It be separated automatically on the conveyor belt. The system can identify boxes to within 1 - 15 cm in length and width and within 5 - 20 cm in height. For the evaluation, some of boxes were sorted into three categories. The experiment result showed that the Automatic Sorting System is able to sort them out with an accuracy of 87.5%.
Meta-analysis of residential exposure to radon gas and lung cancer.

OBJECTIVES To investigate the relation between residential exposure to radon and lung cancer. METHODS A literature search was performed using Medline and other sources. The quality of studies was assessed. Adjusted odds ratios with 95% confidence intervals (CI) for the risk of lung cancer among categories of levels of exposure to radon were extracted. For each study, a weighted log-linear regression analysis of the adjusted odds ratios was performed according to radon concentration. The random effect model was used to combine values from single studies. Separate meta-analyses were performed on results from studies grouped with similar characteristics or with quality scores above or equal to the median. FINDINGS Seventeen case-control studies were included in the meta-analysis. Quality scoring for individual studies ranged from 0.45 to 0.77 (median, 0.64). Meta-analysis based on exposure at 150 Bq/m3 gave a pooled odds ratio estimate of 1.24 (95% CI, 1.11-1.38), which indicated a potential effect of residential exposure to radon on the risk of lung cancer. Pooled estimates of fitted odds ratios at several levels of randon exposure were all significantly different from unity--ranging from 1.07 at 50 Bq/m3 to 1.43 at 250 Bq/m3. No remarkable differences from the baseline analysis were found for odds ratios from sensitivity analyses of studies in which > 75% of eligible cases were recruited (1.12, 1.00-1.25) and studies that included only women (1.29, 1.04-1.60). CONCLUSION Although no definitive conclusions may be drawn, our results suggest a dose-response relation between residential exposure to radon and the risk of lung cancer. They support the need to develop strategies to reduce human exposure to radon.
Similarity measurement in convolutional space

We introduce a method to find the difference of data based on convolution. The method may be used to recognize or verify training data where the number of data classes is unknown or very large in training phase or used as a kernel in an SVM or in an RBF Network. A common solution is to train a machine to maps two input patterns into a new space, which may be high dimensional, such that the output value of the machine approximates the “semantic” distance of input pair. The learning algorithm minimizes an error function which measures the similarity of pair of patterns presented on input layer. In the best case the error function is zero for genuine pairs and is infinity for impostor pairs. The similarity measure is done in convolutional space with Convolutional Neural Network which is robust to spatial distortions. The method is applied on AT&T dataset for face verification task.
The prevalence of female sexual dysfunction among migraine patients

Background: Female sexual dysfunction (FSD) defines as any disorder in the process of sexual contact including 6 main domains, desire, arousal, lubrication, orgasm, orgasm satisfaction and pain. This study was conducted to evaluate prevalence of sexual dysfunction disorder in women with migraine headache and also find the associated factors related to migraine characteristics. Methods: A total of 69 eligible woman patients fulfilling criteria for migraine participated in this study. The Female Sexual Function Index (FSFI), a multi-dimensional self-report implement for appraisal of Female Sexual Function during the past month were utilized in this study. The information related to migraine including frequency, duration of headache attack, severity of headache according to visual analog scale (VAS) score and headache impact test (HIT) score were obtained using a self-administrated questionnaire. Results: About 68.4% of patients had an FSFI score < 28. In domains of desire 73.7%, arousal 64.9%, lubrication 21.1%, orgasm 33.3%, satisfaction 17.5%, and pain 40.4% of patients reported some degree of dysfunction. Among variables related to migraine characteristics, only a significant association between frequency and sexual dysfunction were recorded (P < 0.05). Conclusion: FSD is prevalent among migraine patients. The frequency of a migraine attack is associated with FSD. Serotonin mechanisms such as 5HT2, 5HT3 agonist have been hypothesized as a shared etiology for migraine and sexual dysfunction.
Pan-Cultural Elements in Facial Displays of Emotion

Observers in both literate and preliterate cultures chose the predicted emotion for photographs of the face, although agreement was higher in the literate samples. These findings suggest that the pan-cultural element in facial displays of emotion is the association between facial muscular movements and discrete primary emotions, although cultures may still differ in what evokes an emotion, in rules for controlling the display of emotion, and in behavioral consequences.
Object-based Selection of Irrelevant Features Is Not Confined to the Attended Object

Attention to one feature of an object can bias the processing of unattended features of that object. Here we demonstrate with ERPs in visual search that this object-based bias for an irrelevant feature also appears in an unattended object when it shares that feature with the target object. Specifically, we show that the ERP response elicited by a distractor object in one visual field is modulated as a function of whether a task-irrelevant color of that distractor is also present in the target object that is presented in the opposite visual field. Importantly, we find this modulation to arise with a delay of approximately 80 msec relative to the N2pc—a component of the ERP response that reflects the focusing of attention onto the target. In a second experiment, we demonstrate that this modulation reflects enhanced neural processing in the unattended object. These observations together facilitate the surprising conclusion that the object-based selection of irrelevant features is spatially global even after attention has selected the target object.
Accelerometer-Derived Sedentary and Physical Activity Time in Overweight/Obese Adults with Type 2 Diabetes: Cross-Sectional Associations with Cardiometabolic Biomarkers

Objective To examine the associations of sedentary time and physical activity with biomarkers of cardiometabolic health, including the potential collective impact of shifting mean time use from less- to more-active behaviours (cross-sectionally, using isotemporal substitution), in adults with type 2 diabetes. Methods Participants with overweight/obese body mass index (BMI; ≥25 kg/m2) (n = 279; 158 men, mean [SD] age = 58.2 [8.6] years) wore Actigraph GT1M accelerometers (waking hours; seven days) to assess moderate- to vigorous-intensity physical activity (MVPA), light-intensity activity, and sedentary time (segregated into non-prolonged [accumulated in bouts <30min] and prolonged [accumulated in bouts ≥30 min]). Cross-sectional associations with waist circumference, BMI, fasting blood (HbA1c, glucose, triacylglycerols, high-density lipoprotein cholesterol), and blood pressure of these activity variables (30 min/day increments) were examined adjusted for confounders and wear then, if significant, examined using isotemporal substitution modelling. Results Waist circumference and BMI were significantly (p<0.05) associated with more prolonged sedentary time and less light-intensity activity. Light intensity activity was also significantly associated with lower fasting plasma glucose (relative rate: 0.98, 95% CI: 0.97, 1.00; p<0.05). No biomarker was significantly associated with non-prolonged sedentary time or MVPA. Lower mean prolonged sedentary time (−30 min/day) with higher mean light intensity time (+30 min/day) was significantly associated with lower waist circumference (β = −0.77, 95% CI: −1.33, −0.22 cm). Lower mean prolonged sedentary time (−30 min/day) with either 30 min/day higher mean non-prolonged sedentary time (β = −0.35, 95%CI: −0.70, −0.01 kg/m2) or light-intensity time (β = −0.36, −0.61, −0.11 kg/m2) was associated with significantly lower average BMI. Conclusions Significantly improved mean levels of waist circumference and BMI were observed when shifting time from prolonged sedentary to non-prolonged sedentary or light-intensity activity (cross-sectionally). Lifestyle interventions in overweight/obese adults with type 2 diabetes might consider targeting shifts in these non-MVPA activities to more rigorously evaluate their potential cardiometabolic benefit in this population.
Climate Over the Past Two Millennia

To assess the significance of modern climate change, it is essential to place recent observed changes in a longer-term context. This review assesses the evidence from both “proxy” climate data and theoretical climate model simulations with regard to the nature and causes of climate variability over a time interval spanning roughly the past two millennia. Evidence is reviewed for changes in temperature, drought, and atmospheric circulation over this timescale. Methods for reconstructing past climate from proxy data are reviewed and comparisons with the results of climate modeling studies are provided. The assessment provided affirms the role of natural (solar and volcanic) radiative forcing in past changes in large-scale mean temperature changes and in dynamical modes of climate variability such as the North Atlantic Oscillation (NAO) and El Ni ˜ no/Southern Oscillation (ENSO) influencing large-scale climate. At hemispheric scales, late twentieth century warmth appears unprecedented in the context of at least the past 2000 years. This anomalous warmth can only be explained by modern anthropogenic forcing.
Modulation of proximal muscle function during level versus incline hopping in tammar wallabies (Macropus eugenii)

We examined the functional role of two major proximal leg extensor muscles of tammar wallabies during level and inclined hopping (12°, 21.3% grade). Previous in vivo studies of hopping wallabies have revealed that, unlike certain avian bipeds, distal hindlimb muscles do not alter their force–length behavior to contribute positive work during incline hopping. This suggests that proximal muscles produce the increased mechanical work associated with moving up an incline. Based on relative size and architectural anatomy, we hypothesized that the biceps femoris (BF), primarily a hip extensor, and the vastus lateralis (VL), the main knee extensor, would exhibit changes in muscle strain and activation patterns consistent with increased work production during incline versus level hopping. Our results clearly support this hypothesis. The BF experienced similar activation patterns during level and incline hopping but net fascicle shortening increased (–0.5% for level hopping versus –4.2% for incline hopping) during stance when the muscle likely generated force. Unlike the BF, the VL experienced active net lengthening during stance, indicating that it absorbs energy during both level and incline hopping. However, during incline hopping, net lengthening was reduced (8.3% for level hopping versus 3.9% for incline hopping), suggesting that the amount of energy absorbed by the VL was reduced. Consequently, the changes in contractile behavior of these two muscles are consistent with a net production of work by the whole limb. A subsidiary aim of our study was to explore possible regional variation within the VL. Although there was slightly higher fascicle strain in the proximal VL compared with the distal VL, regional differences in strain were not significant, suggesting that the overall pattern of in vivo strain is fairly uniform throughout the muscle. Estimates of muscle work based on inverse dynamics calculations support the conclusion that both the BF and VL contribute to the additional work required for incline hopping. However, on a muscle mass-specific basis, these two muscles appear to contribute less than their share. This indicates that other hindlimb muscles, or possibly trunk and back muscles, must contribute substantial work during incline hopping.
Schwarz Preconditioners for Stochastic PDEs

Increasingly the spectral stochastic finite element method (SSFEM) has become a popular computational tool for uncertainty quantification in numerous practical engineering problems. For large-scale problems however, the computational cost associated with solving the arising linear system in the SSFEM still poses a significant challenge. The development of efficient and robust preconditioned iterative solvers for the SSFEM linear system is thus of paramount importance for uncertainty quantification of large-scale industrially relevant problems. In the context of high performance computing, the preconditioner must scale to a large number of processors. Therefore in this paper, a twolevel additive Schwarz preconditioner is described for the iterative solution of the SSFEM linear system. The proposed preconditioner can be viewed as a generalization of the mean based block-diagonal preconditioner commonly used in the literature. For the numerical illustrations, two-dimensional steady-state diffusion and elasticity problems with spatially varying random coefficients are considered. The performance of the algorithm is investigated with respect to the geometric parameters, strength of randomness, dimension and order of the stochastic expansion.
Using algorithm visualizations in computer science education

Algorithm visualization illustrates how algorithms work in a graphical way. It mainly aims to simplify and deepen the understanding of algorithms operation. Within the paper we discuss the possibility of enriching the standard methods of teaching algorithms, with the algorithm visualizations. As a step in this direction, we introduce the VizAlgo algorithm visualization platform, present our practical experiences and describe possible future directions, based on our experiences and exploration performed by means of a simple questionnaire.
Becoming a teacher of early reading: charting the knowledge and practices of pre‐service and newly qualified teachers

Education policy in England requires student teachers to demonstrate effective teaching of early reading, including systematic synthetic phonics, in order to qualify to teach. Although there is a range of literature about initial teacher education, little is documented about how pre-service or ‘student’ teachers develop specific knowledge and practices for teaching early reading and how they apply these in their first term as newly qualified teachers (NQTs). This research used a primarily qualitative longitudinal, collective case study design involving seven lower primary (3–7 years) postgraduate certificate in education (PGCE) students enrolled at one university in the East Midlands of England. Semi-structured interviews, classroom observations and documentary analysis with the students and their teacher mentors were used to gather data from entry onto the course to the participants’ first term as qualified teachers. A thematic analysis was applied in conjunction with deductive observation codes developed from a previous study (Louden et. al, 2005). Findings indicate a broad continuum of progression in student and newly qualified teacher knowledge and practice for teaching early reading which could be used to inform university organisation, mentoring and school participation. They highlight the influence of school cultures on the experiences of student and pre-service teachers.
Reaching Transparent Truth

This paper presents and defends a way to add a transparent truth predicate to classical logic, such that ThAi and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STT (for StrictTolerant Truth), is that it supports a nontransitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STT allows for arise in paradoxical cases.
Price Level Targeting vs. Inflation Targeting: A Free Lunch?

Price level targeting (without base drift) and ination targeting (with base drift) are compared, with persistence in output (generated by sticky prices, for instance). Counter to conventional wisdom, price level targeting results in lower short-run ination variability than ination targeting (if output is at least moderately persistent). Price level targeting also eliminates any average ination bias. In case society has preferences corresponding to ination targeting, it may nevertheless prefer to assign price level targeting to the central bank. Price level targeting thus appears to have more advantages than commonly acknowledged.
