Exploring the impact of transformational leadership on nurse innovation behaviour: a cross-sectional study.

AIM
This study explored the influences of transformational leadership on nurse innovation behaviour and the mediating role of organisational climate.


BACKGROUND
Recently, global nursing experts have been aggressively encouraging nurses to pursue innovation in nursing in order to improve nursing outcomes. Nursing innovation, in turn, is affected by nursing leadership.


METHOD
We employed a questionnaire survey to collect data, and selected a sample of nurses from hospitals in Taiwan. A total of 439 valid surveys were obtained. Hierarchical multiple regression model analysis was conducted to test the study hypothesis.


RESULT
The mean values of agreement of nurse innovation behaviour and transformational leadership were 3.40 and 3.78, respectively. Patient safety climate and innovation climate were found to have full mediating effects on the relationship between transformational leadership and innovation behaviour.


CONCLUSION
Organisational climate has a significant impact on innovation behaviour. Transformational leadership has indirect effects on innovation behaviour via the mediation of patient safety climate and innovation climate.


IMPLICATIONS FOR NURSING MANAGEMENT
Hospitals should enhance transformational leadership by designing leadership training programmes and establishing transformational culture. In addition, nursing managers should foster nursing innovation through improvements in organisational climate.
WHAT MALAYSIAN SCIENCE TEACHERS NEED TO IMPROVE THEIR SCIENCE INSTRUCTION: A COMPARISON ACROSS GENDER, SCHOOL LOCATION AND AREA OF SPECIALIZATION

This research looks specifically at the perceived needs of secondary school science teachers in Malaysia so that subsequent effective in-service programmes can be planned and implemented. The prime aim of this cross-sectional survey study is to ascertain the perceived needs of 1,690 practicing secondary school science teachers, characterized by gender, school location, and area of specialization. The main instrument used is a questionnaire. The validity and reliability of the instrument were systematically established through relevant test procedures. The questionnaire seeks feedback on the eight dimensions of science teachers’ needs: generic pedagogical knowledge and skills, knowledge and skills in Science subjects, managing and delivering science instruction, diagnosing and evaluating students, planning science instruction, administering science instructional facilities and equipment, integration of multimedia technology and the use of English language in science instruction. Data were descriptively analyzed, followed by a series of chi square analysis. Results of the descriptive analysis demonstrate that the most prevalent needs of the Malaysian secondary school science teachers are the integration of multimedia and the use of English in science instruction. When measures of association were gauged between the science teachers’ needs and the independent variables, it was found that significant associations exist. The associations were apparent between most of the dimensions of science teachers’ needs and school location.
Depression in pregnancy is associated with preexisting but not pregnancy-induced hypertension.

BACKGROUND
The aim was to examine whether depression is associated with preexisting hypertension or pregnancy-induced hypertension in a large sample of women attending a university-based obstetrics clinic.


METHODS
In this prospective study, participants were 2398 women receiving ongoing prenatal care at a university-based obstetrics clinic from January 2004 through January 2009. Prevalence of depression was measured using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria based on the Patient Health Questionnaire-9 as well as the self-reported use of antidepressant medication. Evidence of preexisting hypertension, pregnancy-induced hypertension and preeclampsia/eclampsia was determined by obstetrician International Classification of Diseases, Ninth Revision codes. Logistic regression was used to quantify the association between hypertension in pregnancy and antenatal depression.


RESULTS
After adjusting for sociodemographic variables, chronic medical conditions, smoking and prior pregnancy complications, women with preexisting hypertension had an increased risk of any depression (minor, major, use of antidepressants) [odds ratio (OR)=1.55, 95% confidence interval (CI) 1.08-2.23) and major depression and/or use of antidepressants (OR=1.65, 95% CI 1.10-2.48) compared to women without hypertension. No differences were seen in risk of depression in women with pregnancy-induced hypertension or preeclampsia/eclampsia compared to those without hypertension.


CONCLUSION
Women with preexisting hypertension, but not pregnancy-induced hypertension, are more likely to meet criteria for an antenatal depressive disorder and/or to be treated with antidepressants and could be targeted by obstetricians for screening for depression and enhanced treatment.
Women With Cardiogenic Shock Derive Greater Benefit From Early Mechanical Circulatory Support: An Update From the cVAD Registry.

OBJECTIVES
The aim of this analysis was to assess survival differences between men and women supported with Impella 2.5 (Abiomed Inc., Danvers) in the setting of acute myocardial infarction (AMI) complicated by cardiogenic shock (CS).


BACKGROUND
Data on sex differences in outcomes of CS with mechanical circulatory support are sparse.


METHODS
Patients enrolled in the cVAD Registry who underwent percutaneous coronary intervention (PCI) and Impella 2.5 support for CS complicating an AMI were included. Differences between men and women were examined.


RESULTS
In total, 180 patients were analyzed. Women (n = 49, 27.2%) were older (71.0 ± 12.8 years vs 63.8 ± 13.0, P = 0.001), smaller (BSA 1.82 ± 0.22 vs 2.04 ± 0.24 m(2) , P < 0.001), and had a higher STS mortality risk score than men (27.9 ± 17.0 vs. 20.8 ± 16.8 P = 0.01). There was no difference in survival to discharge (P = 0.3). Patients receiving the Impella 2.5 pre-PCI had significantly lower inpatient mortality than those who received support post-PCI (P = 0.003). However, the magnitude of the survival benefit was significantly greater in women who received the Impella pre-PCI as compared to men. Overall, 68.8% of women survived with pre-PCI Impella 2.5 versus 24.2% post-PCI (P = 0.005) whereas 54.2% of men survived with pre-PCI Impella 2.5 versus 40.3% post-PCI (P = 0.1, p-interaction = 0.07). No differences in timing to intervention were found between men and women.


CONCLUSIONS
Early initiation of hemodynamic support prior to PCI with Impella 2.5, in the setting of AMI complicated by CS, was associated with a greater survival benefit to hospital discharge in women compared to men, despite a higher predicted risk of mortality and a greater revascularization failure rate for women.

Prognostic Impact of Anemia in Patients With Chronic Heart Failure- With Special Reference to Clinical Background: Report From the CHART-2 Study.

BACKGROUND
We aimed to elucidate the prognostic impact of anemia with special reference to the clinical background of patients with chronic heart failure (CHF).


METHODSANDRESULTS
We examined 4,646 consecutive patients with Stage C/D CHF registered in the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (n=10,219). Among them, 1,627 (35%) had anemia and were characterized by higher age (74 vs. 66 years), lower estimated glomerular filtration rate (52.8 vs. 66.1 ml/min/1.73 m(2)) and higher B-type natriuretic peptide levels (154.5 vs. 81.8 pg/ml) (all P<0.001) but comparable left ventricular ejection fraction (LVEF; 57.5 vs. 56.7%). Anemic patients were more frequently treated with diuretics (55.1 vs. 42.3%) but less often treated with β-blockers (45.4 vs. 51.1%) (both P<0.001). During a median follow-up of 3.8 years, 371 and 272 patients died with and without anemia, respectively (22.8 vs. 9.0%, adjusted hazard ratio 1.40; 95% confidence interval 1.15-1.71, P=0.001). Subgroup analysis revealed that the prognostic impact of anemia was comparable in terms of age, sex, renal function and double product, but differed by LVEF level and CHF etiology (both, P for interaction <0.001). In particular, a difference in the prognostic impact of LVEF level was noted in patients with ischemic heart disease.


CONCLUSIONS
These results indicate that the prognostic impact of anemia is evident in CHF patients with preserved EF and it differs by CHF etiology.
A phase I study of concurrent external beam radiotherapy with weekly topotecan for primary treatment of locally advanced lung cancers.

Copyright © 2012 by the International Association for the Study of Lung Cancer ISSN: 1556-0864/12/712-e44 Doi: 10.1097/JTO.0b013e31826bb94d Penzel et al. recently described a lung adenocarcinoma patient with an EML4-ALK fusion between exon 6 of echinoderm microtubule associated protein like 4 (EML4) and exon 19 of anaplastic lymphoma kinase (ALK) (E6;A19) as a novel molecular variant. It should be noted that this EML4-ALK (E6;A19) fusion has been previously reported by our group in a 62-year-old woman also with lung adenocarcinoma. The second finding of this atypical EML4-ALK breakpoint (the majority of ALK gene fusions occur at exon 20 of ALK) suggests that it may not be an isolated event, and highlights the great diversity of fusion events involving this gene. Furthermore, an FN1-ALK gene fusion was previously identified in a malignant stromal sarcoma patient, in which the fusion also occurs at exon 19 of ALK. The significance of these ALK exon 19 fusion variants is currently unknown, but is interesting as it expresses the ALK transmembrane domain. The subcellular localization of these exon 19-containing variants should be further investigated to better understand the implications of this finding; prior evidence suggests EML4ALK (E13;A20) is localized within the cytoplasm. Oncogenic fusions involving ROS1 and RET in lung cancer have been shown previously to also include the transmembrane domain in some instances. The patient described by our group demonstrated a partial response to crizotinib and experienced a progression free survival of approximately 6.5-months, supporting the argument that these patients be considered for ALK inhibitor therapy like other patients who are positive for ALK rearrangements.
Evaluation of existing District Health Management Information Systems: A case study of the District Health Systems in Kenya

INTRODUCTION
This paper discusses some of the issues and challenges of implementing appropriate and coordinated District Health Management Information System (DHMIS) in environments dependent on external support especially when insufficient attention has been given to the sustainability of systems. It also discusses fundamental issues which affect the usability of DHMIS to support District Health System (DHS), including meeting user needs and user education in the use of information for management; and the need for integration of data from all health-providing and related organizations in the district.


METHODS
This descriptive cross-sectional study was carried out in three DHSs in Kenya. Data was collected through use of questionnaires, focus group discussions and review of relevant literature, reports and operational manuals of the studied DHMISs.


RESULTS
Key personnel at the DHS level were not involved in the development and implementation of the established systems. The DHMISs were fragmented to the extent that their information products were bypassing the very levels they were created to serve. None of the DHMISs was computerized. Key resources for DHMIS operation were inadequate. The adequacy of personnel was 47%, working space 40%, storage space 34%, stationery 20%, 73% of DHMIS staff were not trained, management support was 13%. Information produced was 30% accurate, 19% complete, 26% timely, 72% relevant; the level of confidentiality and use of information at the point of collection stood at 32% and 22% respectively and information security at 48%. Basic DHMIS equipment for information processing was not available. This inhibited effective and efficient provision of information services.


CONCLUSIONS
An effective DHMIS is essential for DHS planning, implementation, monitoring and evaluation activities. Without accurate, timely, relevant and complete information the existing information systems are not capable of facilitating the DHS managers in their day-today operational management. The existing DHMISs were found not supportive of the DHS managers' strategic and operational management functions. Consequently DHMISs were found to be plagued by numerous designs, operational, resources and managerial problems. There is an urgent need to explore the possibilities of computerizing the existing manual systems to take advantage of the potential uses of microcomputers for DHMIS operations within the DHS. Information system designers must also address issues of cooperative partnership in information activities, systems compatibility and sustainability.
Let's Fix OpenGL

From windowing systems to virtual reality, real-time graphics code is ubiquitous. Programming models for constructing graphics software, however, have largely escaped the attention of programming languages researchers. This essay introduces the programming model of OpenGL, a ubiquitous API for real-time graphics applications, for a language-oriented audience. It highlights six broad problems with the programming model and connects them to traditions in PL research. The issues range from classic pitfalls, where established thinking can apply, to new open problems, where novel research is needed. 1998 ACM Subject Classification D.3.m Miscellaneous
Effectiveness of seasonal trivalent influenza vaccine for preventing influenza virus illness among pregnant women: a population-based case-control study during the 2010-2011 and 2011-2012 influenza seasons.

BACKGROUND
Although vaccination with trivalent inactivated influenza vaccine (TIV) is recommended for all pregnant women, no vaccine effectiveness (VE) studies of TIV in pregnant women have assessed laboratory-confirmed influenza outcomes.


METHODS
We conducted a case-control study over 2 influenza seasons (2010-2011 and 2011-2012) among Kaiser Permanente health plan members in 2 metropolitan areas in California and Oregon. We compared the proportion vaccinated among 100 influenza cases (confirmed by reverse transcription polymerase chain reaction) with the proportions vaccinated among 192 controls with acute respiratory illness (ARI) who tested negative for influenza and 200 controls without ARI (matched by season, site, and trimester).


RESULTS
Among influenza cases, 42% were vaccinated during the study season compared to 58% and 63% vaccinated among influenza-negative controls and matched ARI-negative controls, respectively. The adjusted VE of the current season vaccine against influenza A and B was 44% (95% confidence interval [CI], 5%-67%) using the influenza-negative controls and 53% (95% CI, 24%-72%) using the ARI-negative controls. Receipt of the prior season's vaccine, however, had an effect similar to receipt of the current season's vaccine. As such, vaccination in either or both seasons had statistically similar adjusted VE using influenza-negative controls (VE point estimates range = 51%-76%) and ARI-negative controls (48%-76%).


CONCLUSIONS
Influenza vaccination reduced the risk of ARI associated with laboratory-confirmed influenza among pregnant women by about one-half, similar to VE observed among all adults during these seasons.
GPU-Accelerated Deep Shadow Maps for Direct Volume Rendering

Deep shadow maps unify the computation of volumetric and geometric shadows. For each pixel in the shadow map, a fractional visibility function is sampled, pre-filtered, and compressed as a piecewise linear function. However, the original implementation targets software-based off-line rendering. Similar previous algorithms on GPUs focus on geometric shadows and lose many important benefits of the original concept. We focus on shadows for interactive direct volume rendering, where shadow algorithms currently either compute additional per-voxel shadow data, or employ half-angle slicing to generate shadows during rendering. We adapt the original concept of deep shadow maps to volume ray-casting on GPUs, and show that it can provide anti-aliased high-quality shadows at interactive rates. Ray-casting is used for both generation of the shadow map data structure and actual rendering. High frequencies in the visibility function are captured by a pre-computed lookup table for piecewise linear segments. Direct volume rendering is performed with an additional deep shadow map lookup for each sample. Overall, we achieve interactive high-quality volume ray-casting with accurate shadows. To conclude, we briefly describe how semi-transparent geometry such as hair could be integrated as well, provided that rasterization can write to arbitrary locations in a texture. This would be a major step toward full deep shadow map functionality.
Sanctacaris uncata: the oldest chelicerate (Arthropoda)

The morphology of the arthropod Sanctacaris uncata, from the Middle Cambrian Burgess Shale of Canada, is reinterpreted based on a restudy of previously described material. Although originally considered a chelicerate-like arthropod, these affinities were dismissed based primarily on interpretations of the anterior appendages and hypotheses which considered the megacheirans (‘great-appendage’ arthropods) as putative ancestors of chelicerates. The similarities between megacheirans and chelicerates appear to be overstated however, and this study instead reaffirms the identity of putative chelicerate feature in S. uncata and similar arthropods such as Sidneyia and Emeraldella, both also from the Middle Cambrian Burgess Shale. Newly interpreted features, including the presence of pediform exites, multi-partite trunk exopods, and a trunk differentiated into an anterior limb-bearing area and a differentiated posterior limbless abdomen, were coded into an extensive phylogenetic data set of fossil and recent arthropods. In all analyses, Sanctacaris resolved as the basal-most member of total-group Euchelicerata (the least inclusive group including horseshoe crabs and arachnids but not pycnogonids), thus making it the oldest chelicerate in the fossil record. The vicissicaudates (including Sidneyia, Emeraldella, aglaspidids, and cheloniellids—all of which have previously been allied to chelicerates) resolved as sister-taxon to crown-group Chelicerata. This topology indicates that many purported chelicerate features, such as lamellar gills, and a differentiated posterior abdomen evolved sequentially in the chelicerate stem-lineage.
Gameplaying for maths learning: cooperative or not?

This study investigated the effects of gameplaying on fifth-graders’ maths performance and attitudes. One hundred twenty five fifth graders were recruited and assigned to a cooperative Teams-Games-Tournament (TGT), interpersonal competitive or no gameplaying condition. A state standardsbased maths exam and an inventory on attitudes towards maths were used for the pretest and posttest. The students’ gender, socio-economic status and prior maths ability were examined as the moderating variables and covariate. Multivariate analysis of covariance (MANCOVA) indicated that gameplaying was more effective than drills in promoting maths performance, and cooperative gameplaying was most effective for promoting positive maths attitudes regardless of students’ individual differences. Introduction The problem of low achievement in American mathematics education has been discussed in numerous policy reports (Mathematical Sciences Education Board, 2004). Educational researchers (eg Ferrini-Mundy & Schram, 1996) and administrators (eg Brodinsky, 1985), for years, have appealed for mathematics-education reform and proposed various solutions to foster mathematics learning. Amongst these propositions were computer games as powerful mathematical learning tools with great motivational appeal and multiple representations of learning materials (Betz, 1995; Malone, 1981; Moreno, 2002; Quinn, 1994). Researchers reported (eg Ahl, 1981; Bahr & Rieth, 1989; Inkpen, 1994) that a variety of computer games have been used in classrooms to support learning of basic arithmetic and problem-solving skills. Other researchers (Amory, Naicker, Vincent & Adams, 1999; Papert, 1980) contend that computer games need to be carefully aligned with sound learning strategies and 250 British Journal of Educational Technology Vol 38 No 2 2007 © 2006 The Authors.

Consistent with this proposition, the incorporation of computer games within a cooperative learning setting becomes an attractive possibility. Cooperative learning in mathematics has been well discussed by Davidson (1990): group learning helps to remove students’ frustration; it is not only a source for additional help but also offers a support network. Empirical research (Jacobs, 1996; Reid, 1992; Whicker, Bol & Nunnery, 1997) verifies the importance of cooperative learning in mathematics education. Hence, the potential benefit of combining computer games with cooperative learning in mathematics warrants a field investigation. Specific research on the cooperative use of computer games is limited. Empirical study of this technique is especially sparse. Therefore, the purpose of this research was to explore whether computer games and cooperative learning could be used together to enrich K-12 mathematics education. Employing a pretest–posttest experimental design, the study examined the effects of cooperative gameplaying on fifth-grade students’ maths performance and maths attitudes when compared to the interpersonal competitive gameplaying and control groups.
Detection of valvular heart disorders using wavelet packet decomposition and support vector machine

In this study, the valvular heart disorder (VHD) detection method by the wavelet packet (WP) decomposition and the support vector machine (SVM) techniques are proposed. From considering the truth that the frequency ranges of the normal sound and VHDs are different from each other, the WP decomposition at level 8 is employed to split more elaborate frequency bandwidths of the heart sound signals. And then the WP energy (WPE) with the distribution information of energy throughout the whole frequency range of heart sound signals is calculated. Since the heart sound signals with the frequency range of 20–750 Hz are preferred in this study, WPEs at the terminal nodes from (8,1) to (8,47) are selected and two parameters meanWPE and stdWPE as defined by the mean value and standard deviation of the position indices of the terminal nodes with over the weighting value (f) of the maximum value of WPE are proposed as a feature. Furthermore, the SVM technique is employed as the identification tool to classify between the normal sound and VHDs. Finally, a case study on the normal sound, aortic and mitral VHDs is demonstrated to validate the usefulness and efficiency of the VHD detection using WP decomposition and SVM classifier. The experimental results of the proposed VHD detection method showed high performance like the specificity of over 96% and the sensitivity of 100% for both the training and testing data. 2007 Elsevier Ltd.
