Use of a Web Portal for Support and Research After a Disaster: Opportunities and Lessons Learned

Background In this report we describe the development and use of a web portal in the aftermath of the 2004 tsunami. This large scale disaster confronted many displaced people with death, despair and need for information and support. Awareness and insight in the emotional impact of disasters can provide opportunities for surveillance and early treatment. Moreover, online support systems can contribute to community building, empowerment of victims and resilience. Objective We evaluate the development and use of a multilingual web portal that combined a platform for information, emotional support, self assessment and referral with research opportunities. The rapid development, use, advantages, difficulties and learning points are discussed. Methods A multidisciplinary working group from the University Medical Centre Utrecht, the Major Incident Hospital and the Central Military Hospital developed a web portal for tsunami victims. The webportal combined: (1) a forum aimed at community building, (2) self assessment tools that in the same time function as a reseach survey, (3) e-consultation, and (4) an information portal. Results Within 3 weeks after the tsunami, the working group launched an open, online service (www.TISEI.org. Tsunami Intrenational Survey on Emotional Impact) to foster community) support in the aftermath of the disaster. It combined four functionalities that were earlier previously only used separately. The portal had over 36.800 unique visitors in the first two years. At least 31% (144/464) percent of the Dutch surviving victims could be reached for a survey through the site. The TISEI-environment was available in 15 languages and visitors came from all over the world. Ninety-five percent of all visitors came from Europe or the United States. Subsequent to immediate disaster support, the web portal also served as a memorial archive for anniversary meetings and follow-up incentives. Difficulties we experienced were lack of funding, time pressure, victim-anonymisation, international collaboration and long term maintenance. Conclusions A multilingual website with combined modalities for emotional care and research after a natural disaster proved feasible. Web based services like www.TISEI. org in the aftermath of mass disasters can help community building and deliver low level, patient centred and easily accessible information and care. A multilingual website with combined modalities for emotional care and research after a natural disaster proved feasible. Growing Internet penetration world wide and especially the rapid expansion and influence of online communities enables delivery of care and perform research with the internetInternet as a platform. The unpredictable nature of disaster does put time pressure on the development of online solutions and influenced the yield of our site. This highlights the necessity of developing methods and (inter) national collaborations in advance, secure funding, and learn from earlier initiatives.
A PASS Scheme in Cloud Computing-Protecting Data Privacy by Authentication and Secret Sharing

Cloud computing is an emerging IT service paradigm. Instead of developing their own IT departments, business sectors purchase on-demand IT service from external providers in a per-use basis. From business cost perspective, companies are shifting capital expenses (CapExp) on hardware equipments to operational expenses (OpExp). Many companies, especially those startups, found this cloud IT service is economically beneficial. However, this IT service paradigm still requires to overcome some security concerns before it can be fully deployed. One of the main security issues is how to protect client’s data privacy from cloud employees. This paper proposes a PASS scheme for this purpose using Authentication and Secret Sharing.
Improve Knowledge Visualization through an Interactive Graph-based Dashboard System with Key Performance Indicator: A Case Study of University Dashboard for Higher Education

We propose a novel approach of knowledge visualization technique by generating knowledge through a graph-based clustering technique, incorporating tacit knowledge and finally visualizing the knowledge in dashboard form. Three aspects are emphasized: clustering technique, knowledge visualization and domain knowledge interaction. Clustering technique with the feature vectors helps user to mine data from the enterprise database for pattern recognition. The knowledge visualization helps users to analyze the comprehensive characteristics of the objects under study. Subsequently, domain knowledge interaction shall enable the human’s perceptual capabilities to be transferred, thus increases the intelligence of the system. The knowledge visualization is enhanced through the dashboard concept which incorporated with Key Performance Indicator where it provides significant patterns of knowledge on real-world. The framework consists of the knowledge visualization model and a prototype system design for higher education environment is presented in this paper.
The craft and theory of public participation: a dialectical process

This article proposes the craft-theory dialectic as a novel way to conceptualize advancement in the field of public participation. In this perspective, the field is characterized by a rich base of experiential knowledge and a scattered, but growing literature on theory. The chief challenge is to coordinate these two ways of knowing in an iterative, integrative fashion that enables practice to learn from theory and theory to learn from practice. Promoting the development of the craft-theory dialectic should be a central focus for the field. Toward this end this article identifies several key research topics that need attention, explicates these with vignettes from the literature, and discusses the challenges associated with addressing them.
Keck Spectroscopy of Candidate Proto-Globular Clusters in NGC 1275

Keck spectroscopy of five proto–globular cluster candidates in NGC 1275 has been combined with Hubble Space Telescope Wide Field Planetary Camera 2 photometry to explore the nature and origin of these objects and discriminate between merger and cooling-flow scenarios for globular cluster formation. The objects we have studied are not H II regions, but rather star clusters, yet their integrated spectral properties do not resemble young or intermediate-age Magellanic Cloud clusters or Milky Way open clusters. The clusters' Balmer absorption appears to be too strong to be consistent with any of the standard Bruzual & Charlot evolutionary models at any metallicity. If the Bruzual & Charlot models are adopted, an initial mass function (IMF) that is skewed to high masses provides a better fit to the data of the proto–globular cluster candidates. A truncated IMF with a mass range of 2–3 M⊙ reproduces the observed Balmer equivalent widths and colors at ∼450 Myr. Formation in a continuous cooling flow appears to be ruled out since the age of the clusters is much larger than the cooling time, the spatial scale of the clusters is much smaller than the cooling-flow radius, and the deduced star formation rate in the cooling flow favors a steep rather than a flat IMF. A merger would have to produce clusters only in the central few kiloparsecs, presumably from gas in the merging galaxies that was channeled rapidly to the center. Widespread shocks in merging galaxies cannot have produced these clusters. If these objects are confirmed to have a relatively flat, or truncated, IMF, it is unclear whether they will evolve into objects that we would regard as bona fide globular clusters.
Real Asynchronous MPI Communication in Hybrid Codes through OpenMP Communication Tasks

With the number of cores growing faster than memory per node, hybrid programming models (mixing message passing with shared memory paradigms) become a requirement for efficient use of HPC systems. For this scenario, achieving efficient communication is challenging. This is true even when using asynchronous communication, as most MPI implementations can only advance communication inside library calls. In this paper we propose to move communication into a new type of OpenMP task, which gets scheduled as part of the regular OpenMP work-pool. We show for compute intensive iterative stencil algorithms, that this provides real asynchronous communication. Without complicating the programming interface, our results show an excellent performance independent of the communication to computation ratio.
A2A adenosine receptor protects tumors from antitumor T cells

The A2A adenosine receptor (A2AR) has been shown to be a critical and nonredundant negative regulator of immune cells in protecting normal tissues from inflammatory damage. We hypothesized that A2AR also protects cancerous tissues by inhibiting incoming antitumor T lymphocytes. Here we confirm this hypothesis by showing that genetic deletion of A2AR in the host resulted in rejection of established immunogenic tumors in ≈60% of A2AR-deficient mice with no rejection observed in control WT mice. The use of antagonists, including caffeine, or targeting the A2 receptors by siRNA pretreatment of T cells improved the inhibition of tumor growth, destruction of metastases, and prevention of neovascularization by antitumor T cells. The data suggest that effects of A2AR are T cell autonomous. The inhibition of antitumor T cells via their A2AR in the adenosine-rich tumor microenvironment may explain the paradoxical coexistence of tumors and antitumor immune cells in some cancer patients (the “Hellstrom paradox”). We propose to target the hypoxia→adenosine→A2AR pathway as a cancer immunotherapy strategy to prevent the inhibition of antitumor T cells in the tumor microenvironment. The same strategy may prevent the premature termination of immune response and improve the vaccine-induced development of antitumor and antiviral T cells. The observations of autoimmunity during melanoma rejection in A2AR-deficient mice suggest that A2AR in T cells is also important in preventing autoimmunity. Thus, although using the hypoxia→adenosine→A2AR pathway inhibitors may improve antitumor immunity, the recruitment of this pathway by selective drugs is expected to attenuate the autoimmune tissue damage.
On eliciting contribution measures in goal models

Goal models have been found to be useful for supporting the decision making process in the early requirements phase. Through measuring contribution degrees of low-level decisions to the fulfilment of high-level quality goals and combining them with priority statements, it is possible to compare alternative solutions of the requirements problem against each other. But where do contribution measures come from and what is the right way to combine them in order to do such analysis? In this paper we describe how full application of the Analytic Hierarchy Process (AHP) can be used to quantitatively assess contribution relationships in goal models based on stakeholder input and how we can reason about the result in order to make informed decisions. An exploratory experiment shows that the proposed procedure is feasible and offers evidence that the resulting goal model is useful for guiding a decision. It also shows that situation-specific characteristics of the requirements problem at hand may influence stakeholder input in a variety of ways, a phenomenon that may need to be studied further in the context of eliciting such models.
Archery Bow Micro-Movement Profiling Using Inertial Measurement Unit

The micro-movement of archery bow is crucial in determining arhcer's shooting performance. The attachment of Inertial Measurement Unit (IMU) on a bow can provide an insight of the hand-to-grid movement during archers perform anchoring and aiming phases. The movement study of using IMU is captured in this paper to further analyze the low and high frequency components. By applying Fast Fourier Transform (FFT) to the IMU signal, several statistical insight can be gained to understand the micro-movement performance in archery, particularly during the aiming phase. Subsequently, a performance profile can be constructed by obtaining the statistical parameters in the FFT analysis of all elite archers. The average FFT frequency components is devised using a normal distribution, with a standard deviation found at 26Hz. In addition, the top-10 occurrence frequencies reveal that 1Hz, 3Hz, 6Hz, and 10Hz are the most significant frequencies exhibited among all archers. A scoring system is demonstrated by implementing the performance profile and a threshold value to inspect the archers' profiles.
Judgments of Concept Similarity by Normal and Aphasic Subjects: Relation to Naming and Comprehension

A study was conducted in which aphasic patients, age-matched normals, and normal young adults performed five types of matching judgments for object pictures. These required matching for physical identity, basic object identity, and membership in the same superordinate category. Spoken name-to-picture matching was tested for the last two conditions. An analogous set of conditions was presented for letters. Latency patterns across the conditions showed general slowing for the aphasic patients, but with a differential decrement in the conditions that involved auditory (spoken name) input for the matching task. Results showed that variations in semantic judgment capability among the aphasics did not predict the patients' object naming ability.
Birth Order, Graduate School, and Marriage

The results from previous research have shown that firstborn children have both higher needs for achievement and greater needs for affiliation than do later borns. Sampson (1962) found a higher achievement need (see McClelland, 1961) among firstborns than Later borns, and Schachter (1963) discovered that firstborns are over-represented in graduate schools, a finding which also suggests that firstborns have a higher need for achievement. In addition, Schachter (1959) demonstrated that firstborn children showed more evidence of affiliative behavior in response to the arousal of anxiety or distress than later born children, and Smart (1965) found a greater need for affiliation among firstborn males which was reflected in a greater number of club memberships. The present study investigated whether or not firstborns are more likely to be married than later borns while in college. Since early marriage might interfere with long-range options and career plans and limit freedom of movement or mobility, the higher need for achievement of firstborns suggests that they should delay gratification longer and postpone marriage for more years than larer borns. The higher need for affiliation, on the other hand, of firstborns would suggest that they should more likely be married, since marriage is one form of affiliative behavior. The present study tested this hypothesis, and replicated Schacter's (1963) findings of over-representation of firstborns in graduate school. Questionnaires were given to a random sample of 300 married students (276 males, 24 females) attending rhe University of Missouri at Rolla which for the most part consisted of science and engineering majors. Subjects indicated order of birth (first, second, third, etc.) and sex. Thus, the only children were classified with the firstborns and factors such as number of children in the family, age differences between siblings, and the sex of the nearest sibling were not considered. The same questionnaire was also given to a random sample of 143 graduate students (138 males, 5 females) to see if Schachter's (1963) findings of over-representation of firstborns in graduate school could be replicated within this particular specialized, i.e., science and engineering, population of subjects. The results for married students indicated that only 56 6% ( 136 out of 276) married males were firstborn and that only 11 o ut of 24 (45 8% 'i;) married females were firstborn. Since 43% of the general population are firstborn or only children, these results do not differ significantly from chance for either males (x' = .55, df = 1) or females (x' = .17, df = 1). The results for graduate students indicated that 88% of the males (121 out of 138) were firstborns (x3 = 113.81, df = 1, p < .001). Among females, 100% were firstborn (5 out of 5), but the sample size is too small for conclusions. Combining the results for all graduate students. 88.1% were firstborn. While firstborns were tremendously over-represented in graduate school (a confirmation of Schachter's results), they probably did not differ from later borns with regard to being married while in college.
Association of kidney function, vitamin D deficiency, and circulating markers of mineral and bone disorders in CKD.

BACKGROUND Vitamin D (25 hydroxyvitamin D [25(OH)D]) deficiency is common in patients with chronic kidney disease (CKD). Neither the relation of this deficiency to the decrease in glomerular filtration rate (GFR) nor the effects on CKD mineral and bone disorders (MBD) are clearly established. STUDY DESIGN Cross-sectional analysis of baseline data from a prospective cohort, the NephroTest Study. SETTING & PARTICIPANTS 1,026 adult patients with all-stage CKD not on dialysis therapy or receiving vitamin D supplementation. PREDICTORS For part 1, measured GFR (mGFR) using (51)Cr-EDTA renal clearance; for part 2, 25(OH)D deficiency at <15 ng/mL. OUTCOMES & MEASUREMENTS For part 1, 25(OH)D deficiency and several circulating MBD markers; for part 2, circulating MBD markers. RESULTS For part 1, the prevalence of 25(OH)D deficiency was associated inversely with mGFR, ranging from 28%-51% for mGFR ≥60-<15 mL/min/1.73 m(2). It was higher in patients of African origin; those with obesity, diabetes, hypertension, macroalbuminuria, and hypoalbuminemia; and during winter. After adjusting for these factors, ORs for 25(OH)D deficiency increased from 1.4 (95% CI, 0.9-2.3) to 1.4 (95% CI, 0.9-2.1), 1.7 (95% CI, 1.1-2.7), and 1.9 (95% CI, 1.1-3.6) as mGFR decreased from 45-59 to 30-44, 15-29, and <15 (reference, ≥60) mL/min/1.73 m(2) (P for trend = 0.02). For part 2, 25(OH)D deficiency was associated with higher age-, sex-, and mGFR-adjusted ORs of ionized calcium level <1.10 mmol/L (2.6; 95% CI, 1.2-5.9), 1,25 dihydroxyvitamin D concentration <16.7 pg/mL (1.8; 95% CI, 1.3-2.4), hyperparathyroidism (1.8; 95% CI, 1.3-2.4), and serum C-terminal cross-linked collagen type I telopeptides concentration >1,000 pg/mL (1.6; 95% CI, 1.0-2.6). It was not associated with hyperphosphatemia (phosphate >1.38 mmol/L). LIMITATIONS Cross-sectional analysis of the data prevents causal inferences. CONCLUSIONS 25(OH)D deficiency is related independently to impaired mGFR. Both mGFR decrease and 25(OH)D deficiency are associated with abnormal levels of circulating MBD biomarkers.
Effects of Structured Preshot Behaviors on Beginning Golf Performance

Male and female students of beginning golf participated in a “preshot routine” study. 8 men and 7 women learned and practiced a specific routine of actions prior to performing a full swing while 9 men and 6 women (controls) practiced only the swing. Subjective and objective performance measures were completed before and after the 8-wk. training session. Trained men had higher posttraining scores than controls and trained women, but no significant differences were found between trained women and other groups on either measure. As trained men had superior skill before and after training, perhaps a certain level of skill must be established before the preshot routine is effective.
Structure of Dark Matter Halos from Hierarchical Clustering

We investigate the structure of the dark matter halo formed in the cold dark matter scenario using N-body simulations. We simulated 12 halos with masses of 6.6 × 1011-8.0 × 1014 M☉. In all runs, the halos have density cusps proportional to r-1.5 developed at their centers, which is consistent with the results of recent high-resolution calculations. The density structure evolves in a self-similar way and is universal in the sense that it is independent of the halo mass and initial random realization of density fluctuation. The density profile is in good agreement with the profile proposed by Moore et al., which has a central slope proportional to r-1.5 and an outer slope proportional to r-3. The halo grows through repeated accretion of diffuse smaller halos. We argue that the cusp is understood as a convergence slope for the accretion of tidally disrupted matter.
A Lightening Fine-grained Access Control Scheme Supporting Full Policy Hiding in Cloud Storage

Efficiency, security, and flexibility are difficult to balance in a full policy hiding CP-ABE scheme. This paper creatively converts the privacy matching problem of access policy and a user’s private key to the privacy three-party set computation problem. Then the new privacy set computation problem is resolved by a message driven key generation method. Additionally, the ROBDD (Reduced Ordered Binary Decision Diagrams) is utilized to rich access structure expression and convert access policies into feasible path sets. Each feasible path is composed of attributes and these attributes are bound to the ciphertext using CP-ABE. Based on the innovative ideas mentioned above, we present a Lighten Fine-grained Access Control scheme supporting Full Policy Hidden (LFAC-FPH) that integrates data confidentiality protection, access policy rich expression but complete hiding, fine-grained access control, and lightweight terminal computing. Our scheme has three advantages: 1) High Efficiency. The proposed scheme can achieve fast privacy matching of access policies during user decryption. 2) Full Policy Hiding. The access policy bound by an owner on the ciphertext does not leak any information. Moreover, a user cannot know attributes they do not own. 3) High Flexibility. The decryption process does not require online from owners or KGC, and system attributes can be added at any time.
Import and spread of Panton-Valentine Leukocidin-positive Staphylococcus aureus through nasal carriage and skin infections in travelers returning from the tropics and subtropics.

BACKGROUND Antibiotic-resistant Staphylococcus aureus is a globally emerging pathogen. Exchangeable virulence factors, such as Panton-Valentine leukocidin (PVL), have been proposed to drive this epidemic. We investigated whether skin infections and nasal colonization in travelers contribute to the global spread of such strains. METHODS We conducted a case-control study of 38 returnees from the tropics and subtropics with S. aureus-positive skin and soft tissue infections (SSTIs) and 124 control patients with other travel-associated disorders. We collected information on travel characteristics, clinical outcomes of SSTIs, antibiotic sensitivity patterns, and genotypes of S. aureus strains isolated from skin lesions and the nares. RESULTS S. aureus-positive SSTIs were associated with travel duration and purpose and were most common in returnees from Africa (odds ratio, 4.2; P = .005). PVL-positive (PVL(+)) S. aureus was frequent in the lesional and nasal isolates from travelers with SSTIs but could not be found in the nares of the control patients. The presence of PVL in S. aureus in travelers was associated with complicated disease, reduced antibiotic susceptibility, and secondary spread. The genotypes of PVL(+) S. aureus in returnees were reported to be endemic to the visited destination but rarely observed in Europe. CONCLUSIONS Geographic variation in the risk of SSTIs in travelers supports a globally heterogeneous distribution of virulent S. aureus. Complicated SSTIs in returnees from nontemperate climates are associated with PVL(+) S. aureus and promote the emergence and spread of virulent and antibiotic-resistant strains. We propose a network for the surveillance of imported S. aureus (www.staphtrav.eu).
