Synthesis of single-walled carbon nanotube–Co–MgO composite powders and extraction of the nanotubes

A carbon nanotube–Co–MgO composite powder is prepared by reducing a Mg0.9Co0. 1O solid solution in H2–CH4 atmosphere. The oxide matrix and part of the Co catalyst are dissolved by acid treatment without damage to the nanotubes. More than 80% of the carbon nanotubes have either one or two walls. The diameters of the nanotubes are in the range 0.5–5 nm. The utilized method may be a real improvement in the low-cost, large-scale synthesis of single- and double-walled carbon nanotubes.
The Miracle Bearers: Narratives of Birthing Women and Implications for Spiritually Informed Social Work Practice

ABSTRACT Women's childbirth experiences are not widely researched in the social work literature. Therefore, the purpose of this study is to answer questions related to the child-birthing experience. One hundred and nineteen participants responded to a 26-item online questionnaire between April and June 2008, and their written narratives were analyzed using a grounded theory approach. Themes regarding the spiritual dimensions of childbirth emerged from the data and support current research demonstrating the importance of spirituality in women's lives and the meaningful and transformative nature of childbirth experiences. Implications for addressing spirituality in practice when working with childbearing women are explored. Future research that explores how spirituality may function as a protective factor for women with difficult pregnancies, births, and transitions to parenting is recommended.
Predictors of Treatment Completion in a Correctional Sex Offender Treatment Program

The purpose of this study was to examine what factors increase the likelihood that a sex offender will complete a correctional sex offender treatment program. Participants were 179 incarcerated adult male sex offenders who volunteered to participate in a sex offender treatment program. The two groups evaluated were treatment completers and noncompleters. By examining archival records the following data were collected: scores on the Multiphasic Sex Inventory II (MSI II), the Minnesota Multiphasic Personality Inventory (MMPI), the Abel and Becker Adult Sexual Interest Card Sort, and plethysmograph. Demographic information was obtained from presentence investigation reports. Results from a logistic regression indicate that more years of education, not having a history of sexual victimization, and lower levels of minimizing or excusing sexual crimes predict treatment completion (p < .05). These results suggest that it is possible to predict which incarcerated sex offenders are likely to complete a prison-based sex offender treatment program.
Single-Image Super-Resolution Using Active-Sampling Gaussian Process Regression

As well known, Gaussian process regression (GPR) has been successfully applied to example learning-based image super-resolution (SR). Despite its effectiveness, the applicability of a GPR model is limited by its remarkably computational cost when a large number of examples are available to a learning task. For this purpose, we alleviate this problem of the GPR-based SR and propose a novel example learning-based SR method, called active-sampling GPR (AGPR). The newly proposed approach employs an active learning strategy to heuristically select more informative samples for training the regression parameters of the GPR model, which shows significant improvement on computational efficiency while keeping higher quality of reconstructed image. Finally, we suggest an accelerating scheme to further reduce the time complexity of the proposed AGPR-based SR by using a pre-learned projection matrix. We objectively and subjectively demonstrate that the proposed method is superior to other competitors for producing much sharper edges and finer details.
2010 2nd International Conference on Industrial and Information Systems a Cross-layer Flooding Strategy for Wireless Sensor Networks

Abstra ct-Flooding is a kind of broadcast technology in wireless sensor networks. And it is used in many occasions, such as routing, time synchronization and so on. But large­ scale and intense flooding may cause broadcast storm, which aggravates the resource consumption in wireless sensor networks and leads to network congestion. In this paper, we propose a cross-layer flooding strategy for wireless sensor networks. The proposed flooding protocol makes use of the received signal power to decide the backoff time, which is an important parameter for medium access control, and thus reduces redundant broadcast packets and collisions. Analyses and simulations have shown that the new flooding protocol has much fewer redundant broadcast packets and can reduce energy consumption .
Laboratory and Field Evaluation of Polymerase Chain Reaction-Based Forensic DNA Profiling for Use in Identification of Human Blood Meal Sources ofAedes aegypti(Diptera: Culicidae)

Abstract We modified polymerase chain reaction (PCR)-based forensic DNA profiling for field studies on the feeding behavior ofAedes aegypti,the principal mosquito vector of dengue virus. Human DNA was extracted from oral swabs of human subjects and from blood-engorged mosquitoes, DNA was quantified by slot blot, and alleles at variable number tandem repeats and three short tandem repeats loci were amplified by PCR. Alleles were separated electrophoretically and then visualized by silver staining. A custom software program was written to match DNA fingerprints of potential human hosts to allelic profiles detected in engorged mosquitoes, and to calculate error rates for identification of human hosts of single and multiple-host blood meals. At 29°C in the laboratory, human DNA recovered from mosquito blood meals declined an average of 67% 8 h after feeding and 90% after 24 h. We obtained complete allelic profiles from seven of 10 mosquitoes collected after 24 h. In a field trial, complete DNA profiles were obtained successfully for 43 people living in a rural village in south central Thailand and for 20 of 100Ae. aegyptithat contained blood and were collected in those peoples’ homes. Blood imbibed from more than one person was detected in 45% (9 of 20) of the meals. Sixty-five percent of the meals contained blood from nonresidents of the house in which the mosquito was collected or from people who were not profiled; data consistent with the hypothesis that human movement is important for the spread of dengue virus within and among communities. When using alleles at four loci, all of the Thais and nine members spanning three generations of a Chinese-American family had unique allelic profiles. Error rates from classifying possible multiple-host meals as single-host meals were low (1–8%), with the highest error associated with closely related people. Results from our laboratory and field studies indicated that DNA profiling can be used to study the details and epidemiological implications ofAe. aegyptiblood-feeding behavior.
4-D frequency selective extrapolation for error concealment in multi-view video

Practical applications for multi-view video such as three-dimensional television may require to transmit the data over error-prone channels. Even when channel coding is used, it is likely that parts of the image information are lost after decoding. To improve the image quality in this case, an efficient algorithm for multi-view error concealment is presented. Extending and enhancing a previously known method for single-view concealment, the algorithm simultaneously uses information from surrounding image parts, from temporally preceding and succeeding frames and from neighbouring camera views for extrapolating known image samples into the lost area. It is shown that the proposed algorithm leads to convincing results in terms of PSNR as well as to a good subjective quality. Compared to single-view concealment, the result is improved by up to 0.75 dB by adding cross-view information.
Risk of hip, subtrochanteric, and femoral shaft fractures among mid and long term users of alendronate: nationwide cohort and nested case-control study

Objectives To determine the skeletal safety and efficacy of long term (≥10 years) alendronate use in patients with osteoporosis. Design Open register based cohort study containing two nested case control studies. Setting Nationwide study of population of Denmark. Participants 61 990 men and women aged 50-94 at the start of treatment, who had not previously taken alendronate, 1996-2007. Interventions Treatment with alendronate. Main outcome measures Incident fracture of the subtrochanteric femur or femoral shaft (ST/FS) or the hip. Non-fracture controls from the cohort were matched to fracture cases by sex, year of birth, and year of initiation of alendronate treatment. Conditional logistic regression models were fitted to calculate odds ratios with and without adjustment for comorbidity and comedications. Sensitivity analyses investigated subsequent treatment with other drugs for osteoporosis. Results 1428 participants sustained a ST/FS (incidence rate 3.4/1000 person years, 95% confidence interval 3.2 to 3.6), and 6784 sustained a hip fracture (16.2/1000 person years, 15.8 to 16.6). The risk of ST/FS was lower with high adherence to treatment with alendronate (medication possession ratio (MPR, a proxy for compliance) >80%) compared with poor adherence (MPR <50%; odds ratio 0.88, 0.77 to 0.99; P=0.05). Multivariable adjustment attenuated this association (adjusted odds ratio 0.88, 0.77 to 1.01; P=0.08). The risk was no higher in long term users (≥10 dose years; 0.70, 0.44 to 1.11; P=0.13) or in current compared with past users (0.91, 0.79 to 1.06; P=0.22). Similarly, MPR >80% was associated with a decreased risk of hip fracture (0.73, 0.68 to 0.78; P<0.001) as was longer term cumulative use for 5-10 dose years (0.74, 0.67 to 0.83; P<0.001) or ≥10 dose years (0.74, 0.56 to 0.97; P=0.03). Conclusions These findings support an acceptable balance between benefit and risk with treatment with alendronate in terms of fracture outcomes, even for over 10 years of continuous use.
Referral selection bias in the Medicare hospital mortality prediction model: are centers of referral for Medicare beneficiaries necessarily centers of excellence?

OBJECTIVE Although the Health Care Financing Administration (HCFA) uses Medicare hospital mortality data as a measure of hospital quality of care, concerns have been raised regarding the validity of this concept. A problem that has not been fully evaluated in these data is the potential confounding effect of illness severity factors associated with referral selection and hospital mortality on comparisons of risk-adjusted hospital mortality. We address this issue. DATA SOURCES AND STUDY SETTING We analyzed the 1988 Medicare hospitalization data file (MEDPAR). We selected data on patients treated at the two Mayo Clinic-associated hospitals in Rochester, Minnesota, and a group of seven other hospitals that treat many patients from large geographic areas. These hospitals have had observed mortality rates substantially lower than those predicted by the HCFA model for the period 1987-1990. STUDY DESIGN Using the multiple logistic regression model applied by HCFA to the 1988 data, we evaluated the relationship between distance from patient residence to the admitting hospital and risk-adjusted hospital mortality. PRINCIPAL FINDINGS Among patients admitted to Mayo Rochester-affiliated hospitals, residence outside Olmsted County, Minnesota was independently associated with a 33 percent lower 30-day mortality rate (p < .001) than that associated with residence in Olmsted County. When patients at Mayo hospitals were stratified by residence (Olmsted County versus non-Olmsted County), the observed mortality was similar to that predicted for community patients (9.6 percent versus 10.2 percent, p = .26), whereas hospital mortality for referral patients was substantially lower than predicted (5.0 percent versus 7.5 percent, p = < .001). After incorporation of the HCFA risk adjustment methods, distance from patient residence to the hospitals was also independently associated with mortality among the Mayo Rochester-affiliated hospitals and seven other referral center hospitals. CONCLUSIONS The HCFA Medicare hospital mortality model should be used with extreme caution to evaluate hospital quality of care for national referral centers because of residual confounding due to severity of illness factors associated with geographic referral that are inadequately captured in the extant prediction model.
Comparison of three techniques for ovarian pedicle hemostasis during laparoscopic-assisted ovariohysterectomy.

OBJECTIVE To describe the safety, surgical time, and complications associated with 3 techniques for achieving hemostasis during laparoscopic-assisted ovariohysterectomy (LAOVH). STUDY DESIGN Prospective, randomized clinical trial. ANIMALS Female dogs (n=30). METHODS Dogs were randomly assigned to 1 of 3 methods for achieving ovarian pedicle hemostasis during LAOVH: extracorporeal modified Roeder knot application (suture group), metal clip application using a multifire 10 mm laparoscopic clip applier (clip group), or use of a novel 5 mm bipolar vessel-sealing device (vessel-sealing group). In all dogs a 3 median portal technique was used. RESULTS Controlling for the dogs' bodyweights, there was a significant association between surgical time and which method for hemostasis was used. This association was different when comparing the first 5 procedures using each method to the second 5. For a 20 kg dog, the surgical time (95% CI) for the first 5 procedures was 80 (69-91), 68 (57-79), and 33 (21-45) minutes for the suture, clip, and vessel-sealing groups, respectively. For the second 5 procedures surgical time was 71 (60-81), 50 (39-60), and 40 (29-51) minutes. Pedicle hemorrhage occurred in all dogs in the clip group, 3 dogs in the suture group, and none of the dogs in the vessel-sealing group although in all cases was considered hemodynamically inconsequential. All dogs recovered uneventfully. CONCLUSIONS All methods of hemostasis were safe for pedicle sectioning. A learning curve exists for clip and suture methods. CLINICAL RELEVANCE Use of a vessel-sealing device significantly shortens surgical time and provides excellent hemostasis during LAOVH.
Elderly Gait Analysis and Assessment Based on Body Area Network

As the nerve cell of the Internet of Things, WSN (wireless sensor network) have been the most important part of our life. Even more WBSN (wireless body sensor network) as one kind of WSN have been one part of our body. Sensor technology, Computer technology, wireless technology, semiconductor technology and so on all these development has made sensor network node so smaller, lighter and more multifunctional that can be dressed in portably. The sensor nodes can sample many of vital signals such as ECG, EEG, EKG, SPO2, body-temperature, Glucose, Heart Rate and so on, activities of daily living and gait information, environment information. All of information collected is transferred to extracorporeal data center. Based on the information collected something related to health can be analyzed.
AMHP work: dirty or prestigious?:dirty work designations and the approved mental health professional

The paper explores the notion of ‘dirty work’ in relation to the newly created role of the Approved Mental Health Professional (AMHP). An AMHP undertakes various duties set out in the 1983 Mental Health Act, as amended by the 2007 Act, in relation to assessments to make applications for compulsory admission to psychiatric hospital. It has been argued that undertaking this social control function is ‘dirty work’. However, the findings from a study of social work AMHPs in England suggest that the picture is more complex. Extracts from narrative interviews are analysed using dialogical narrative analysis. Rather than being designated as dirty work, AMHP duty was presented as prestigious and as advanced social work. However, through their storytelling, the social workers clearly delineated the aspects of AMHP work that they did designate as dirty, specifically the lack of beds, the complexities of co-ordination and the emotional labour which is an inherent part of the work.
Applying a Causal Analytic Framework to the Mobley, Horner, and Hollingsworth (1978) Turnover Model: A Useful Reexamination

Mobley, Horner, and Hollingsworth (1978) have proposed a sequential decisional model of the employee withdrawal process. In their model, cognitive and behavioral variables mediate the job satisfaction and turnover relationship. The authors of that model presented an explicit causal structure which has yet to be examined with causal analysis. In the present study, a path-analytic approach was used to conduct such an examination using the original data, which Mobley et al. derived from a sample of 203 full-time hospital employees from four general job categories: service, technical, clerical, and nursing services. The results of our analysis provide support for the general theoretical structure of the Mobley et al. model, but also point to more complexity in some of the model's hypothesized relations.
Parallel and Convergent Evolution of the Dim-Light Vision Gene RH1 in Bats (Order: Chiroptera)

Rhodopsin, encoded by the gene Rhodopsin (RH1), is extremely sensitive to light, and is responsible for dim-light vision. Bats are nocturnal mammals that inhabit poor light environments. Megabats (Old-World fruit bats) generally have well-developed eyes, while microbats (insectivorous bats) have developed echolocation and in general their eyes were degraded, however, dramatic differences in the eyes, and their reliance on vision, exist in this group. In this study, we examined the rod opsin gene (RH1), and compared its evolution to that of two cone opsin genes (SWS1 and M/LWS). While phylogenetic reconstruction with the cone opsin genes SWS1 and M/LWS generated a species tree in accord with expectations, the RH1 gene tree united Pteropodidae (Old-World fruit bats) and Yangochiroptera, with very high bootstrap values, suggesting the possibility of convergent evolution. The hypothesis of convergent evolution was further supported when nonsynonymous sites or amino acid sequences were used to construct phylogenies. Reconstructed RH1 sequences at internal nodes of the bat species phylogeny showed that: (1) Old-World fruit bats share an amino acid change (S270G) with the tomb bat; (2) Miniopterus share two amino acid changes (V104I, M183L) with Rhinolophoidea; (3) the amino acid replacement I123V occurred independently on four branches, and the replacements L99M, L266V and I286V occurred each on two branches. The multiple parallel amino acid replacements that occurred in the evolution of bat RH1 suggest the possibility of multiple convergences of their ecological specialization (i.e., various photic environments) during adaptation for the nocturnal lifestyle, and suggest that further attention is needed on the study of the ecology and behavior of bats.
Digital Strategies in Action: a Comparative Analysis of National Data Infrastructure Development

In recent years, many countries have started to draft strategies and policies related to the data economy. To support new data-driven activities and innovations, the development of a national data infrastructure (NDI) is seen as key. The concept of NDI has entered governmental strategic discussions on data as an asset, the role of data infrastructures in innovation and economic activity, and the role of government therein. However, there is a gap between the ambitions as laid out in the strategies and the actual actions taken towards realizing them. To understand this gap and support NDI development, insight is needed in the components and processes of realizing NDI strategies. In this paper, we study NDI strategies 'in action' in the Netherlands and Switzerland using an analytical framework comprising strategies, stakeholders, design, components and governance. Special emphasis is put on the role of government in formulating and implementing strategies. Our cross-case analysis uncovers lessons that seem relevant for NDI development elsewhere, as well as challenges that need to be resolved before NDIs can hope actually make the impact associated with them.
The role of negative affectivity in the stress process: Tests of alternative models

The prominence of the personality trait of Negative Affectivity (NA) in the stress literature has increased over the last decade. Negative affectivity has been widely reported both to have direct effects on measures of strain, and to act as a potential confounding variable of stressor–strain relations in self-report research (Watson and Clark, 1984). However, more recent work has demonstrated that NA can also moderate environment–outcome relationships, acting as a vulnerability factor in the stress model, or alternatively that its influence may be mediated through perceptions of the work environment. In the present study, these four possible pathways through which NA may be implicated in job satisfaction and symptom report were examined. In terms of symptom report, NA was found to have direct effects, to act as a partial confound, and to play a significant moderating (vulnerability) role. In contrast, for the prediction of job satisfaction, the influence of NA was found to be mediated through perceptions of the work environment. It is concluded that all these potential roles of NA should be more thoroughly considered in future stress research.
An approach for continuous inspection of source code

With multiple developers engaged in collaboratively writing software code, responsibility for a specific piece of code is difficult to assign. Nonetheless, responsibility is a major factor in achieving quality and preventing code from being developed carelessly. We present a new approach for statistically acquiring per developer per document accountabilities and enable learning and self-monitoring processes within a development team while maintaining anonymity to a certain degree in order to not endanger team spirit.
