Structural health monitoring of civil infrastructure

Structural health monitoring (SHM) is a term increasingly used in the last decade to describe a range of systems implemented on full-scale civil infrastructures and whose purposes are to assist and inform operators about continued ‘fitness for purpose’ of structures under gradual or sudden changes to their state, to learn about either or both of the load and response mechanisms. Arguably, various forms of SHM have been employed in civil infrastructure for at least half a century, but it is only in the last decade or two that computer-based systems are being designed for the purpose of assisting owners/operators of ageing infrastructure with timely information for their continued safe and economic operation. This paper describes the motivations for and recent history of SHM applications to various forms of civil infrastructure and provides case studies on specific types of structure. It ends with a discussion of the present state-of-the-art and future developments in terms of instrumentation, data acquisition, communication systems and data mining and presentation procedures for diagnosis of infrastructural ‘health’.
The Value of Incomplete Information: Do Better Informed Investors Always Do Better?

Investor rationality ensures that the possession of additional information is always advantageous, but experimental findings suggest more nuanced effects. We investigate this issue using data from a singular source: auctions of yearling racehorses (akin to ‘equine IPOs’). Like IPO insiders, breeders have superior information about their own horses, but those they choose to repurchase subsequently perform worse, earning about 30% less at the racetrack than horses purchased by outsiders: breeders effectively sell their winners and retain their losers. We consider a wide range of rational, behavioural, and statistical explanations for this puzzling finding, but none finds much support. A little knowledge can apparently be dangerous, although the exact mechanism by which this occurs is unclear.
A Test of the “Sexy Son” Hypothesis: Sons of Polygynous Collared Flycatchers Do Not Inherit Their Fathers’ Mating Status

According to the original “sexy son” hypothesis, a female may benefit from pairing with an already‐mated male despite a reduction in fecundity because her sons inherit their father’s attractiveness. We used data from a long‐term study of collared flycatchers (Ficedula albicollis) collected during 24 years to test this prediction. Our results show that the sons of polygynously mated females fledged in poor condition and therefore did not inherit their father’s large forehead patch (a condition‐dependent display trait) or mating status. From the female’s perspective, polygynous pairing resulted in fewer recruited grandchildren than did a monogamous pairing. The reproductive value of sons did not outweigh the fecundity costs of polygyny because the low paternal care reduced the attractiveness of sons. When there are long‐lasting parental effects on offspring attractiveness, costs of polygyny may include the production of nonsexy sons.
Traumatic Events and Mental Health in the Community: a New Zealand Study

Background: Adverse mental health effects in response to a variety of distressing events in specific populations are well documented. However, comparatively little research has been conducted within large community samples outside North America. Aims: To assess the prevalence and psychological impact of specific traumatic events in a New Zealand community sample. Methods: Prevalence and psychological impact of 12 traumatic events was examined in a community sample of 1,500 New Zealand adults using a three-stage cluster sampling method. Traumatic events, psychological distress, psychological well-being, and post-traumatic stress disorder symptoms were assessed using modifi ed versions of the Traumatic Stress Schedule, Mental Health Inventory, and Civilian Mississippi Scale. The effects of age, gender and ethnicity were controlled for while assessing impact of traumatic events. Results: Sixty-one per cent of the sample experienced trauma events in their lifetime, with 9% experiencing events in the past year. Accident-related events were most common in the present sample. Violent crime produced the greatest impact. Tests of interactions involving age, gender, and ethnicity were not significant. Conclusions: New Zealand community-residing individuals experience post-traumatic stress symptoms, reduced psychological well-being, and increased psychological distress following the experience of violent crime and accidents specifically. Study limitations and suggestions for future research are discussed.

The first part of the paper deals with the literature on strategic management, systems thinking approach, and customer-focused strategies. The second part includes the summary discussions of selected PNG companies' strategic analysis of their respective markets. The third part deals with the strategic options and their relevance to the global and organisational levels in PNG. The fourth part discusses the recommendations for new strategic options to meet the challenges PNG companies experienced from the current global-stimuli of change.
Combat‐Related Posttraumatic Stress Disorder: Patterns of Symptomatology in Help‐Seeking Vietnam Veterans

Sixty-one Vietnam veterans who had sought outpatient psychological services were evaluated for posttraumatic stress disorder (PTSD) during two independent diagnostic interviews. Data were analyzed from only those 48 subjects for whom the two diagnoses agreed upon the presence or absence of PTSD. Subjects were administered the Symptom Checklist-90-R, a modified version of the Impact of Event Scale, and two measures of combat stress: the Combat Scale Revised and the Vietnam Experience Scale. Some support was generated for the reliability and validity of the PTSD construct as outlined in DSM-III. In our sample the diagnosis of PTSD was associated with excessive arousal characterized by anxiety, anger, paranoid ideation, intrusive images, and avoidance of stimuli reminiscent of the traumatic stressor. The findings are discussed in relation to previous studies of combat-related PTSD and studies of traumatically stressed civilians.
Regional glucose utilization and blood flow following graded forebrain ischemia in the rat: Correlation with neuropathology

Regional patterns of cerebral glucose utilization (rCMRglc) and blood flow (rCBF) were examined in the early recovery period following transient forebrain ischemia in order to correlate early postischemic physiological events with regionally selective patterns of ischemic neuropathology. Wistar rats were subjected to 30 or 60 minutes of graded forebrain ischemia by a method combining unilateral occlusion of the common carotid artery with moderate elevation of intracranial pressure and mild hypotension; this procedure results in a high‐grade ischemic deficit affecting chiefly the lateral neocortex, striatum, and hippocampus ipsilateral to the carotid occlusion. Simultaneous measurements of rCMRglc and rCBF made in regional tissue samples after 2 and 4 hours of postischemic recirculation using a double‐tracer radioisotopic strategy revealed a disproportionately high level of glucose metabolism relative to blood flow in the early postischemic striatum, owing to the resumption of nearly normal rCMRglc in the face of depressed flow. In contrast, the neocortex, which had been equally ischemic, showed parallel depressions of both metabolism and blood flow during early recovery. Light microscopy at 4 and 8 hours after recovery revealed the striatum to be the predominant locus of ischemic neuronal alterations, whereas neocortical lesions were much less prominent in extent and severity at this time. The resumption of normal levels of metabolism in the setting of a disproportionate depression of rCBF in the early postischemic period may accentuate the process of neuronal injury initiated by ischemia and may contribute to the genesis of neuronal necrosis in “selectively vulnerable” areas of the forebrain.
Fibromyalgia diagnosis and diagnostic criteria

Abstract Criteria for fibromyalgia developed from the conceptualization and hypotheses of Smythe and Moldofsky in 1977 and gradually evolved to a set of classification criteria endorsed by the American College of Rheumatology that emphasized tender points and widespread pain, measures of decreased pain threshold. In 2010, American College of Rheumatology fibromyalgia diagnostic criteria were published that abandoned the tender point count and placed increased emphasis of patient symptoms. The 2010 criteria also contained severity scales and offered physicians the opportunity to assess polysymptomatic distress on a continuous scale. This enabled physicians who were opposed to the idea of fibromyalgia to also assess and diagnose patients using an alternative nomenclature.
Rosuvastatin might have an effect on C-reactive protein but not on rheumatoid disease activity: Tayside randomized controlled study

The aim of this study was to study the effects of rosuvastatin in patients with rheumatoid arthritis (RA) looking at the C-reactive protein (CRP), interleukin-6 (IL-6) and joint disease activity. Fifty RA patients were randomized in a double-blind placebo-controlled trial to receive either 10 mg of rosuvastatin or placebo as an adjunct to existing disease-modifying antirheumatic therapy. Patients were followed up for a six-month period. Measurements were done at baseline and six months. CRP and IL-6 were measured in the blood. RA disease activity was measured using disease activity score based on 28 joint counts (DAS 28). When analysing from baseline to six months there was no difference between the rosuvastatin and placebo groups in rheumatoid disease activity (–0.01; standard deviation [SD], 1.08; and +0.18; SD, 0.95; respectively; P value 0.509). There was a trend towards improvement in CRP in the rosuvastatin group (–3.23; SD, 18.18) compared with the placebo group (+17.43; SD, 38.03); P value, 0.161. IL-6 showed a trend towards worsening in the rosuvastatin group (+0.15; SD, 1.09) compared with placebo (–0.73; SD, 1.4); P value, 0.054. These data show that rosuvastatin with might decrease the CRP independent to IL-6 in patients with RA but does not improve the overall rheumatoid disease activity.
The Perception of Complications in Pediatric Spine Surgery: A Comparative Survey of Surgeons, Caregivers and Patients

Background/Aims: The perception of a surgical complication may differ between surgeons and patients. In pediatric spine surgery, the perception of the parent or primary caregiver may also differ. In order to better define these relationships, we performed a pilot study surveying a convenience sample of pediatric spinal surgeons, patients and their parent or primary caregiver. We hope to use this initial pilot study as a starting point for future research into this incompletely defined, yet increasingly relevant topic. Methods: A survey of case vignettes describing a potential perioperative complication was administered to 14 pediatric spine surgeons at the Texas Children’s Hospital Pediatric NeuroSpine Clinic from June 1 to July 31, 2009. The same survey, with modified language, was presented to a group of 13 pediatric patients (age range: 12–18 years). In addition, the surveys were separately presented to 34 primary caregivers of pediatric patients evaluated in a spine surgery clinic. The 61 respondents were asked to evaluate the cases and determine if there was a minor, a major or no complication present. Fisher’s exact test was employed to evaluate associations of respondent groups and complication severity. Results: There were no statistically significant differences in the proportion of patients and caregivers rating the presence of complications. In 8 of 13 cases, a majority of surgeons and a majority of patients/caregivers felt a complication was present (all p > 0.06). A greater proportion of surgeons than patients/caregivers felt a complication was present in 2 cases of transient neurological deficit/paraparesis (6 weeks to 6 months; p < 0.04) and 1 case of cosmetically significant pressure sores to the face (p = 0.0002). A greater proportion of patients/caregivers identified a complication in a loss of range of motion after occipitocervical fusion (p < 0.0001) and a loss of motor evoked potentials without a neurological deficit. Amongst those who identified a complication, a greater proportion of surgeons considered the following as a ‘major’ complication: malpositioned spinal instrumentation with a return to the operating room (p = 0.02); transient new neurological deficit (p < 0.01), and deep wound infection with return to the operating room (p < 0.01). In no scenario did a greater proportion of patients/caregivers consider the complication ‘major’ compared to surgeons. Conclusions: In this pilot study, there appear to be differences in how postoperative complications are perceived by surgeons when compared to patients/caregivers. The importance of reconciling such differing opinions through open discussions between surgeons, patients and their families is integral to ensure congruent expectations of planned surgical interventions.
Association of transmission intensity and age with clinical manifestations and case fatality of severe Plasmodium falciparum malaria.

CONTEXT There are concerns that malaria control measures such as use of insecticide-treated bed nets, by delaying acquisition of immunity, might result in an increase in the more severe manifestations of malaria. An understanding of the relationships among the level of exposure to Plasmodium falciparum, age, and severity of malaria can provide evidence of whether this is likely. OBJECTIVE To describe the clinical manifestations and case fatality of severe P falciparum malaria at varying altitudes resulting in varying levels of transmission. DESIGN, SETTING, AND PATIENTS A total of 1984 patients admitted for severe malaria to 10 hospitals serving populations living at levels of transmission varying from very low (altitude >1200 m) to very high (altitude <600 m) in a defined area of northeastern Tanzania, studied prospectively from February 2002 to February 2003. Data were analyzed in a logistic regression model and adjusted for potential clustering within hospitals. MAIN OUTCOME MEASURES Specific syndromes of severe malaria; mortality. RESULTS The median age of patients was 1 year in high transmission, 3 years in moderate transmission, and 5 years in low transmission areas. The odds of severe malarial anemia (hemoglobin <5 g/dL) peaked at 1 year of age at high transmission and at 2 years at moderate and low transmission intensities and then decreased with increasing age (P = .002). Odds were highest in infants (0-1 year: referent; 2-4 years: odds ratio [OR], 0.83; 95% confidence interval [CI], 0.72-0.96), 5 to <15 years: OR, 0.44; 95% CI, 0.27-0.72; > or =15 years: OR, 0.44; 95% CI, 0.27-0.73; P<. 001) and high transmission intensity areas (altitude <600 m: referent; 600 m to 1200 m: OR, 0.55; 95% CI, 0.35-0.84; >1200 m: OR, 0.55; 95% CI, 0.26-1.15; P for trend = .03). The odds of cerebral malaria were significantly higher in low transmission intensity areas (altitude of residence <600 m: referent; 600 m to 1200 m: OR, 3.17; 95% CI, 1.32-7.60; >1200 m: OR, 3.76; 95% CI, 1.96-7.18; P for trend = .003) and with age 5 years and older (0-1 year: referent; 2-4 years: OR, 1.57; 95% CI, 0.82-2.99; 5 to <15 years: OR, 6.07; 95% CI, 2.98-12.38; > or =15 years: OR, 6.24; 95% CI, 3.47-11.21; P<.001). The overall case-fatality rate of 7% (139 deaths) was similar at high and moderate levels of transmission but increased to 13% in low transmission areas (P = .03), an increase explained by the increase in the proportion of cases with cerebral malaria. CONCLUSIONS Age and level of exposure independently influence the clinical presentation of severe malaria. Our study suggests that an increase in the proportion of cases with more fatal manifestations of severe malaria is likely to occur only after transmission has been reduced to low levels where the overall incidence is likely to be low.
A computerized support tool for conducting a scrum-based software engineering capstone course

A software engineering capstone course is often used for the introduction of agile methods like Scrum. Apart fromexposing students to state-of-the-art topics, the capstone course also enables teachers to use modern ways of teachingthrough practical problem solving and gives researchers opportunities to conduct empirical studies with students assubjects. In order to satisfy the needs of all parties involved, a good computerized support tool is needed. The students needsuch a tool to manage their projects, the teachers require instruments for maintaining project requirements and monitoringstudent progress, while the researchers are interested in data for evidence-driven assessment of the development process. Inthis paper, an example of such a tool that was developed to support a Scrum-based software engineering capstone course isdescribed. The course design, which requires students to develop a quasi-real project, is described first. Following this, astep-by-step description of the course execution is provided and the tool support of each step is illustrated. Finally, theopinions of 57 students obtained through an anonymous survey after using the tool for the first time are analyzed. Thestudents found the tool intuitive and easy to use, providing good visualization of the project progress and making theexecution of their projects simpler and more efficient. The tool gives directions on how their collaboration should proceedand prevents them from exploring their projects blindly. By visualizing the development process, it helps all partiesinvolved to know what each team member is doing, thus preventing procrastination and ‘‘free-rider’’ syndrome.
Unsupervised Characterization and Visualization of Students' Academic Performance Features

The large nature of students’ dataset has made it difficult to find patterns associated with students’ academic performance (AP) using conventional methods. This has increased the rate of drop-outs, graduands with weak class of degree (CoD) and students that spend more than the minimum stipulated duration of studies. It is necessary to determine students’ AP using educational data mining (EDM) tools in order to know students who are likely to perform poorly at an early stage of their studies. This paper explores k-means and self-organizing map (SOM) in mining pieces of knowledge relating to the natural number of clusters in students’ dataset and the association of the input features using selected demographic, pre-admission and first year performance. Matlab 2015a was the programming environment and the dataset consists of nine sets of computer science graduands. Cluster validity assessment with k-means discovered four (4) clusters with correlation metric yielding the highest mean silhouette value of 0.5912. SOM provided an hexagonal grid visual of feature component planes and scatter plots of each significant input attribute. The result shows that the significant attributes were highly correlated with each other except entry mode (EM), indicating that the impact of EM on CoD varies with students irrespective of mode of admission. Also, four distinct clusters were also discovered in the dataset by SOM —7.7% belonging to cluster 1 (first class), and 25% for cluster 2 (2nd class Upper) while Clusters 3 and 4 had 35% proportion each. This validates the results of k-means and further confirms the importance of early detection of students’ AP and confirms the effectiveness of SOM as a cluster validity tool. As further work, the labels from SOM will be associated with records in the dataset for association rule mining, supervised learning and prediction of students’ AP.
Evaluation of the prognostic value of pSMAD immunohistochemistry in colorectal cancer

SMAD4 mutations and recent genome-wide association studies (GWAS) show the importance of bone morphogenetic protein (BMP) and transforming growth factor-&bgr; (TGF-&bgr;) signalling in the development of colorectal cancer (CRC). Loss of SMAD4 has been implicated as a predictive marker in CRC. As activation of the BMP and TGF-&bgr; pathways leads to phosphorylation of SMAD1,5,8 and SMAD2,3, respectively, and both need SMAD4 for translocation to the nucleus, we aimed to investigate whether nuclear staining of pSMAD1,5,8 and pSMAD2, 3 can be used as predictive markers in CRC. A tissue microarray (TMA) was constructed using tissue from 209 patients diagnosed with CRC. TMA was stained and scored for the nuclear presence of SMAD4, pSMAD2,3 and pSMAD1,5,8. Loss of SMAD4, pSMAD2,3 and pSMAD1,5,8 was observed in 40, 38 and 73% of the cases, respectively. The incidence of SMAD4 loss was significantly higher in the advanced stages. There was a correlation between loss of SMAD4 and loss of pSMAD1,5,8, but not between loss of SMAD4 and loss of pSMAD2,3. Loss of SMAD4 correlated with a poorer survival. Loss of one of the pSMADs did not correlate with a poorer outcome. Combining different SMAD stainings did not improve the prediction. SMAD4 expression is a prognostic marker in CRC. Nuclear expressions of pSMAD1,5,8 and pSMAD2,3 are not useful prognostic markers in CRC.
Trends in antibiotic resistance of respiratory pathogens: an analysis and commentary on a collaborative surveillance study.

The evolution of antibiotic resistance was studied among common respiratory tract pathogens in five countries of the European Union and in the USA during 1992-1993. The data obtained from a collaborative surveillance study were submitted to population analysis, to detect possible shifts in antibiotic susceptibility and, therefore, associated mechanisms of resistance. Among the emerging haemophilus influenzae phenotypes were isolates that did not correspond to the beta-lactamase negative, amino-penicillin resistant (BLNAR) phenotype, but were beta-lactamase producers showing low level ceftriaxone resistance (early extended spectrum beta-lactamases? ) amoxycillin susceptible strains with low level ceftriaxone resistance (PBP modification? ) and isolates with high-level fluoroquinolone resistance. Moraxella catarrhalis resistance to ceftriaxone erythromycin or fluoroquinolones was noted. The quantitative evolution of antibiotic resistance may reach saturation in some countries with a very high proportion of resistant strains, for example, Spain and France. Qualitatively, resistant strains may be selected that have broader or more effective mechanisms of resistance, particularly under the recently introduced pressure of more active antibiotics of the same family. In countries with modest levels of antibiotic resistance (UK, Germany, Italy), attention should be paid to the misuse of antibiotics with a propensity to select low-level resistant strains. In this respect, the relative prescribing of aminopenicillins and oral cephalosporins in the UK (a high ratio and low prevalence of Streptococcus pneumoniae) and resistance to penicillin in the USA (a low ratio and high prevalence of resistance) is of potential importance.
