Storyboard augmentation of process model grammars for stakeholder communication

Process models are often used to visualize and communicate workflows to involved stakeholders. Unfortunately, process modeling notations can be complex and need specific knowledge to be understood. Storyboards, as a visual language to illustrate workflows as sequences of images, provide natural visualization features that allow for better communication, to provide insight to people from non-process modeling expert domains. This paper proposes a visualization approach using a 3D virtual world environment to visualize storyboards for business process models. A prototype was built to present its applicability via generating output with examples of five major process model patterns and two non-trivial use cases. Illustrative results for the approach show the promise of using a 3D virtual world to visualize complex process models in an unambiguous and intuitive manner.
Effects of anonymity, invisibility, and lack of eye-contact on toxic online disinhibition

0747-5632/$ see front matter 2011  A doi:10.1016/j.chb.2011.10.014 ⇑ Corresponding author.  E-mail address: noaml@yvc.ac.il (N. Lapidot-Lefler The present research studied the impact of three typical online communication factors on inducing the toxic online disinhibition effect: anonymity, invisibility, and lack of eye-contact. Using an experimental design with 142 participants, we examined the extent to which these factors lead to flaming behaviors, the typical products of online disinhibition. Random pairs of participants were presented with a dilemma for discussion and a common solution through online chat. The effects were measured using participants’ self-reports, expert judges’ ratings of chat transcripts, and textual analyses of participants’ conversations. A 2 2 2 (anonymity/non-anonymity visibility/invisibility eye-contact/lack of eye-contact) MANOVA was employed to analyze the findings. The results suggested that of the three independent variables, lack of eye-contact was the chief contributor to the negative effects of online disinhibition. Consequently, it appears that previous studies might have defined the concept of anonymity too broadly by not addressing other online communication factors, especially lack of eye-contact, that impact disinhibition. The findings are explained in the context of an online sense of unidentifiability, which apparently requires a more refined view of the components that create a personal sense of anonymity.
An inductive peaking technology for high-speed MIPI receiver bandwidth expanding in a 90 nm CMOS process

An inductive peaking technology is proposed in this paper for improving receiver bandwidth. A N/PMOS cross biasing active inductor and negative Miller capacitance are introduced to provide inductive peaking around the amplifier bandwidth. According to the simulation and experimental results within a MIPI receiver under 1.2V CMOS 90nm process, the inductive peaking technology increases the bandwidth of the preamplifier in the MIPI PHY circuit from 1.05GHz to 2.09GHz. As a results, the PHY circuit which employs the inductive peaking amplifier consumes only 4mW power for transferring 1Gbps data signal with 70mV differential amplitude to 1.2V CMOS level.
Topic Augmented Neural Response Generation with a Joint Attention Mechanism

We consider incorporating topic information as prior knowledge into the sequence to sequence (Seq2Seq) network structure with attention mechanism for response generation in chatbots. To this end, we propose a topic augmented joint attention based Seq2Seq (TAJASeq2Seq) model. In TAJA-Seq2Seq, information from input posts and information from topics related to the posts are simultaneously embedded into vector spaces by a content encoder and a topic encoder respectively. The two kinds of information interact with each other and help calibrate weights of each other in the joint attention mechanism in TAJA2Seq2Seq, and jointly determine the generation of responses in decoding. The model simulates how people behave in conversation and can generate well-focused and informative responses with the help of topic information. Empirical study on large scale human judged generation results show that our model outperforms Seq2Seq with attention on both response quality and diversity.
A Three-Dimensional Model of Women’s Empowerment: Implications in the Field of Microfinance and Future Directions

Women's empowerment is an important goal in achieving sustainable development worldwide. Offering access to microfinance services to women is one way to increase women's empowerment. However, empirical evidence provides mixed results with respect to its effectiveness. We reviewed previous research on the impact of microfinance services on different aspects of women's empowerment. We propose a Three-Dimensional Model of Women's Empowerment to integrate previous findings and to gain a deeper understanding of women's empowerment in the field of microfinance services. This model proposes that women's empowerment can take place on three distinct dimensions: (1) the micro-level, referring to an individuals' personal beliefs as well as actions, where personal empowerment can be observed (2) the meso-level, referring to beliefs as well as actions in relation to relevant others, where relational empowerment can be observed and (3) the macro-level, referring to outcomes in the broader, societal context where societal empowerment can be observed. Importantly, we propose that time and culture are important factors that influence women's empowerment. We suggest that the time lag between an intervention and its evaluation may influence when empowerment effects on the different dimensions occur and that the type of intervention influences the sequence in which the three dimensions can be observed. We suggest that cultures may differ with respect to which components of empowerment are considered indicators of empowerment and how women's position in society may influence the development of women's empowerment. We propose that a Three-Dimensional Model of Women's Empowerment should guide future programs in designing, implementing, and evaluating their interventions. As such our analysis offers two main practical implications. First, based on the model we suggest that future research should differentiate between the three dimensions of women's empowerment to increase our understanding of women's empowerment and to facilitate comparisons of results across studies and cultures. Second, we suggest that program designers should specify how an intervention should stimulate which dimension(s) of women's empowerment. We hope that this model inspires longitudinal and cross-cultural research to examine the development of women's empowerment on the personal, relational, and societal dimension.
Impunity or immunity: wartime male rape and sexual torture as a crime against humanity.

This paper seeks to analyze the phenomenon of wartime rape and sexual torture of Croatian and Iraqi men and to explore the avenues for its prosecution under international humanitarian and human rights law. Male rape, in time of war, is predominantly an assertion of power and aggression rather than an attempt on the part of the perpetrator to satisfy sexual desire. The effect of such a horrible attack is to damage the victim's psyche, rob him of his pride, and intimidate him. In Bosnia- Herzegovina, Croatia, and Iraq, therefore, male rape and sexual torture has been used as a weapon of war with dire consequences for the victim's mental, physical, and sexual health. Testimonies collected at the Medical Centre for Human Rights in Zagreb and reports received from Iraq make it clear that prisoners in these conflicts have been exposed to sexual humiliation, as well as to systematic and systemic sexual torture. This paper calls upon the international community to combat the culture of impunity in both dictator-ruled and democratic countries by bringing the crime of wartime rape into the international arena, and by removing all barriers to justice facing the victims. Moreover, it emphasizes the fact that wartime rape is the ultimate humiliation that can be inflicted on a human being, and it must be regarded as one of the most grievous crimes against humanity. The international community has to consider wartime rape a crime of war and a threat to peace and security. It is in this respect that civilian community associations can fulfill their duties by encouraging victims of male rape to break their silence and address their socio-medical needs, including reparations and rehabilitation.
An Automated Antenna Measurement System Utilizing Wi-Fi Hardware

We propose a system that measures three-dimensional gain patterns of an unknown antenna using the received signal-strength indicator (RSSI) provided by Wi-Fi hardware. Our system uses widely available Wi-Fi routers to generate the RF signal and to measure incident power. A simple two-axis positioner allows the full three-dimensional pattern of the antenna to be measured, and a LabVIEW interface lets users control measurements and view results. We make use of inexpensive, readily available materials and rudimentary construction techniques.
Acupuncture for patients with migraine: a randomized controlled trial.

Acupuncture is widely used to prevent migraine attacks, but the available evidence of its benefit is scarce.



To investigate the effectiveness of acupuncture compared with sham acupuncture and with no acupuncture in patients with migraine.



Three-group, randomized, controlled trial (April 2002-January 2003) involving 302 patients (88% women), mean (SD) age of 43 (11) years, with migraine headaches, based on International Headache Society criteria. Patients were treated at 18 outpatient centers in Germany.



Acupuncture, sham acupuncture, or waiting list control. Acupuncture and sham acupuncture were administered by specialized physicians and consisted of 12 sessions per patient over 8 weeks. Patients completed headache diaries from 4 weeks before to 12 weeks after randomization and from week 21 to 24 after randomization.



Difference in headache days of moderate or severe intensity between the 4 weeks before and weeks 9 to 12 after randomization.



Between baseline and weeks 9 to 12, the mean (SD) number of days with headache of moderate or severe intensity decreased by 2.2 (2.7) days from a baseline of 5.2 (2.5) days in the acupuncture group compared with a decrease to 2.2 (2.7) days from a baseline of 5.0 (2.4) days in the sham acupuncture group, and by 0.8 (2.0) days from a baseline if 5.4 (3.0) days in the waiting list group. No difference was detected between the acupuncture and the sham acupuncture groups (0.0 days, 95% confidence interval, -0.7 to 0.7 days; P = .96) while there was a difference between the acupuncture group compared with the waiting list group (1.4 days; 95% confidence interval; 0.8-2.1 days; P<.001). The proportion of responders (reduction in headache days by at least 50%) was 51% in the acupuncture group, 53% in the sham acupuncture group, and 15% in the waiting list group.



Acupuncture was no more effective than sham acupuncture in reducing migraine headaches although both interventions were more effective than a waiting list control.
A MODIS-Based Novel Method to Distinguish Surface Cyanobacterial Scums and Aquatic Macrophytes in Lake Taihu

Satellite remote sensing can be an effective alternative for mapping cyanobacterial scums and aquatic macrophyte distribution over large areas compared with traditional ship’s site-specific samplings. However, similar optical spectra characteristics between aquatic macrophytes and cyanobacterial scums in red and near infrared (NIR) wavebands create a barrier to their discrimination when they co-occur. We developed a new cyanobacteria and macrophytes index (CMI) based on a blue, a green, and a shortwave infrared band to separate waters with cyanobacterial scums from those dominated by aquatic macrophytes, and a turbid water index (TWI) to avoid interference from high turbid waters typical of shallow lakes. Combining CMI, TWI, and the floating algae index (FAI), we used a novel classification approach to discriminate lake water, cyanobacteria blooms, submerged macrophytes, and emergent/floating macrophytes using MODIS imagery in the large shallow and eutrophic Lake Taihu (China). Thresholds for CMI, TWI, and FAI were determined by statistical analysis for a 2010–2016 MODIS Aqua time series. We validated the accuracy of our approach by in situ reflectance spectra, field investigations and high spatial resolution HJ-CCD data. The overall classification accuracy was 86% in total, and the user’s accuracy was 88%, 79%, 85%, and 93% for submerged macrophytes, emergent/floating macrophytes, cyanobacterial scums and lake water, respectively. The estimated aquatic macrophyte distributions gave consistent results with that based on HJ-CCD data. This new approach allows for the coincident determination of the distributions of cyanobacteria blooms and aquatic macrophytes in eutrophic shallow lakes. We also discuss the utility of the approach with respect to masking clouds, black waters, and atmospheric effects, and its mixed-pixel effects.
Submitted to the Annals of Statistics CHANGE-POINT DETECTION IN MULTINOMIAL DATA WITH A LARGE NUMBER OF CATEGORIES By

We consider a sequence of multinomial data for which the probabilities associated with the categories are subject to abrupt changes of unknown magnitudes at unknown locations. When the number of categories is comparable to or even larger than the number of subjects allocated to these categories, conventional methods such as the classical Pearson’s chi-squared test and the deviance test may not work well. Motivated by high-dimensional homogeneity tests, we propose a novel change-point detection procedure that allows the number of categories to tend to infinity. The null distribution of our test statistic is asymptotically normal and the test performs well with finite samples. The number of change-points is determined by minimizing a penalized objective function based on segmentation, and the locations of the change-points are estimated by minimizing the objective function with the dynamic programming algorithm. Under some mild conditions, the consistency of the estimators of multiple change-points is established. Simulation studies show that the proposed method performs satisfactorily for identifying change-points in terms of power and estimation accuracy, and it is illustrated with an analysis of a real data set.
AUTOMATED GRADING OF PROSTATE CANCER USING ARCHITECTURAL AND TEXTURAL IMAGE FEATURES

The current method of grading prostate cancer on histology uses the Gleason system, which describes five increasingly malignant stages of cancer according to qualitative analysis of tissue architecture. The Gleason grading system has been shown to suffer from inter- and intra-observer variability. In this paper we present a new method for automated and quantitative grading of prostate biopsy specimens. A total of 102 graph-based, morphological, and textural features are extracted from each tissue patch in order to quantify the arrangement of nuclei and glandular structures within digitized images of histological prostate tissue specimens. A support vector machine (SVM) is used to classify the digitized histology slides into one of four different tissue classes: benign epithelium, benign stroma, Gleason grade 3 adenocarcinoma, and Gleason grade 4 adenocarcinoma. The SVM classifier was able to distinguish between all four types of tissue patterns, achieving an accuracy of 92.8% when distinguishing between Gleason grade 3 and stroma, 92.4% between epithelium and stroma, and 76.9% between Gleason grades 3 and 4. Both textural and graph-based features were found to be important in discriminating between different tissue classes. This work suggests that the current Gleason grading scheme can be improved by utilizing quantitative image analysis to aid pathologists in producing an accurate and reproducible diagnosis
Fecal calprotectin more accurately reflects endoscopic activity of ulcerative colitis than the Lichtiger Index, C-reactive protein, platelets, hemoglobin, and blood leukocytes.

The correlation between noninvasive markers with endoscopic activity according to the modified Baron Index in patients with ulcerative colitis (UC) is unknown. We aimed to evaluate the correlation between endoscopic activity and fecal calprotectin (FC), C-reactive protein (CRP), hemoglobin, platelets, blood leukocytes, and the Lichtiger Index (clinical score).



UC patients undergoing complete colonoscopy were prospectively enrolled and scored clinically and endoscopically. Samples from feces and blood were analyzed in UC patients and controls.



We enrolled 228 UC patients and 52 healthy controls. Endoscopic disease activity correlated best with FC (Spearman's rank correlation coefficient r = 0.821), followed by the Lichtiger Index (r = 0.682), CRP (r = 0.556), platelets (r = 0.488), blood leukocytes (r = 0.401), and hemoglobin (r = -0.388). FC was the only marker that could discriminate between different grades of endoscopic activity (grade 0, 16 [10-30] μg/g; grade 1, 35 [25-48] μg/g; grade 2, 102 [44-159] μg/g; grade 3, 235 [176-319] μg/g; grade 4, 611 [406-868] μg/g; P < 0.001 for discriminating the different grades). FC with a cutoff of 57 μg/g had a sensitivity of 91% and a specificity of 90% to detect endoscopically active disease (modified Baron Index ≥ 2).



FC correlated better with endoscopic disease activity than clinical activity, CRP, platelets, hemoglobin, and blood leukocytes. The strong correlation with endoscopic disease activity suggests that FC represents a useful biomarker for noninvasive monitoring of disease activity in UC patients.
A COMPARATIVE STUDY ON LOSSY IMAGE COMPRESSION TECHNIQUES

Image compression is used specially for the compression of images where tolerable degradation is required. With the wide use of computers and consequently need for large scale storage and transmission of data, efficient ways of storing of data have become necessary. With the growth of technology and entrance into the Digital Age, the world has found itself amid a vast amount of information. Dealing with such enormous information can often present difficulties. Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level. The reduction in file size allows more images to be stored in a given amount of disk or memory space. It also reduces the time required for images to be sent over the Internet or downloaded from Web pages.JPEG and JPEG 2000 are two important techniques used for image compression. In this paper, we discuss about lossy image compression techniques and reviews of different basic lossy image compression methods are considered. The methods such as JPEG and JPEG2000 are considered. A conclusion is derived on the basis of these methods  Data compression, Lossy image compression, JPEG, JPEG2000, DCT, DWT
Dietary sensitivities and ADHD symptoms: thirty-five years of research.

Artificial food colors (AFCs) have not been established as the main cause of attention-deficit hyperactivity disorder (ADHD), but accumulated evidence suggests that a subgroup shows significant symptom improvement when consuming an AFC-free diet and reacts with ADHD-type symptoms on challenge with AFCs. Of children with suspected sensitivities, 65% to 89% reacted when challenged with at least 100 mg of AFC. Oligoantigenic diet studies suggested that some children in addition to being sensitive to AFCs are also sensitive to common nonsalicylate foods (milk, chocolate, soy, eggs, wheat, corn, legumes) as well as salicylate-containing grapes, tomatoes, and orange. Some studies found "cosensitivity" to be more the rule than the exception. Recently, 2 large studies demonstrated behavioral sensitivity to AFCs and benzoate in children both with and without ADHD. A trial elimination diet is appropriate for children who have not responded satisfactorily to conventional treatment or whose parents wish to pursue a dietary investigation.
Action research in the physics classroom : the impact of authentic , inquiry based learning or instruction on the learning of thermal physics

Students experience thermal physics phenomena from a very young age, but in Singapore their formal science instruction occurs in Primary 3 or 4 (aged 9 or 10) and again in secondary school (aged 13 to 16). Hence, students often form alternative or incomplete scientific conceptions related to thermal physics well before they begin learning it in the science classroom. The team of teachers involved in this study, therefore, believed that traditional instruction would be largely ineffective because it does not take into account students’ existing beliefs about thermal physics. An action research process was undertaken to investigate if a more interactive and engaging pedagogical approach, such as authentic, inquiry based learning, could make students’ thinking more explicit through discussions and other social interactions. Three intact classes of Secondary-3 students were selected: a high-performing control group and a low-performing control group using Traditional Physics Instruction (TPI) and an experimental group using Authentic Inquiry-Based Instruction (AIBI). Students in the experimental group demonstrated significant gains in conceptual understanding and student self-efficacy, although students in the high-performing control group continued to outscore students in the experimental group. Further analysis of the data revealed a correlation between students’ achievement on a standardised test and conceptual understanding of the subject matter in the AIBI classroom. Traditional forms of instruction are inadequate because they do little to develop students’ self-efficacy and interest in the subject matter. More emphasis should be placed on embedding authentic and formative assessment tasks within the curriculum, rather than end-of-unit standardised tests.
Financial Crises : Theory and Evidence

Financial crises have occurred for many centuries. They are often preceded by a credit boom and a rise in real estate and other asset prices, as in the current crisis. They are also often associated with severe disruption in the real economy. This paper surveys the theoretical and empirical literature on crises. The first explanation of banking crises is that they are a panic. The second is that they are part of the business cycle. Modeling crises as a global game allows the two to be unified. With all the liquidity problems in interbank markets that have occurred during the current crisis, there is a growing literature on this topic. Perhaps the most serious market failure associated with crises is contagion, and there are many papers on this important topic. The relationship between asset price bubbles, particularly in real estate, and crises is discussed at length.
