Do Acute Myocardial Infarction and Heart Failure Readmissions Flagged as Potentially Preventable by the 3M Potentially Preventable Readmissions Software Have More Process-of-Care Problems?

Background—The 3M Potentially Preventable Readmissions (3M-PPR) software matches clinically related index admission and readmission diagnoses that may signify in-hospital or postdischarge quality problems. To assess whether the PPR algorithm identifies preventable readmissions, we compared processes of care between PPR software-flagged and nonflagged cases. Methods and Results—Using 2006 to 2010 national VA administrative data, we identified acute myocardial infarction and heart failure discharges associated with 30-day all-cause readmissions, then flagged cases (PPR-Yes/PPR-No) using the 3M-PPR software. To assess care quality, we abstracted medical records of 100 readmissions per condition using tools containing explicit processes organized into admission work-up, in-hospital evaluation/treatment, discharge readiness, postdischarge period. We derived quality scores, scaled to a maximum of 25 per section (maximum total score=100) and compared cases on total and section-specific mean scores. For acute myocardial infarction, 77 of 100 cases were flagged as PPR-Yes. Section quality scores were highest for in-hospital evaluation/treatment (20.5±2.8) and lowest for postdischarge care (6.8±9.1). Total and section-related mean scores did not differ by PPR status; respective PPR-Yes versus PPR-No total scores were 61.6±11.1 and 60.4±9.4; P=0.98. For heart failure, 86 of 100 cases were flagged as PPR-Yes. Section scores were highest for discharge readiness (18.8±2.4) and lowest for postdischarge care (7.3±8.1). Like acute myocardial infarction, total and section-related mean scores did not differ by PPR status; PPR-Yes versus PPR-No total scores were 61.2±10.8 and 63.4±7.0, respectively; P=0.47. Conclusions—Among VA acute myocardial infarction and heart failure readmissions, the 3M-PPR software does not distinguish differences in case-level quality of care. Whether 3M-PPR software better identifies preventable readmissions by using other methods to capture poorly documented processes or performing different comparisons requires further study.

Existing searches in unstructured peer-to-peer (P2P) networks are either blind or informed based on simple heuristics. Blind schemes suffer from low query quality. Simple heuristics lack theoretical background to support the simulation results. In this paper, we propose an intelligent searching scheme, called intelligent search by reinforcement learning (ISRL), which systematically seeks the best route to desired files by reinforcement learning (RL). In artificial intelligence, RL has been proven to be able to learn the best sequence of actions to achieve a certain goal. To discover the best path to desired files, ISRL not only explores new paths by forwarding queries to randomly chosen neighbors, but also exploits the paths that have been discovered for reducing the cumulative query cost. We design three models of ISRL: a basic version for finding one desired file, MP-ISRL for finding at least k files, and C-ISRL for reducing maintenance overhead through clustering when there are many queries. ISRL outperforms existing searching approaches in unstructured P2P networks by achieving similar query quality with lower cumulative query cost. The experimental result confirms the performance improvement of ISRL.
Comparison of MIMO antenna configurations in picocell and microcell environments

This paper presents the results achieved with a dual-polarized multiple-input multiple-output (MIMO) measurement system in the 2 GHz range. Results from continuous measurement routes were used in evaluating and comparing different MIMO antenna configurations. Different pattern and polarization diversity possibilities were studied using two methods: elements were selected from the antenna arrays used in measurements, and as another option, in the mobile station the incident waves were estimated and used in different dipole antenna arrays. The capacity limit seems to be higher in an indoor picocell than in an outdoor microcell environment. At the mobile station, directive elements result in 35% higher average capacities than those of the omnidirectional elements; however, the capacity of the directive elements also depends on the azimuth direction of arrival of the incident field. Dual-polarized antenna configurations have approximately 14% higher capacities than copolarized configurations. Increasing the number of mobile antenna elements increases the capacity in those environments where the angular spread of the incident field is large. Increasing the distance between elements at the fixed station increases the capacity - especially in microcells where signals arrive from specific directions.
Annotated Bibliography of Publications Related to Teacher Evaluation

THIS BIBLIOGRAPHY, relating to teachj er evaluation, came about as one phase of work of the Committee on Rating in the Chicago Pub lic Schools. Charged with the responsibility for revising and improving the procedures of teach er and principal evaluation in the school system, the Committee has in two years of activity, sur veyed and studied the literature of research and the philosophical approaches in the aims and ob jectives of school personnel evaluation. Such in vestigation was fundamental to the development of the new instruments and procedures now in experimental use in connection with the evalua tion of a large sample of teachers and principals. It is felt that basic to a professionally accept able evaluation plan is wide participation of school staff in the development and improvement of meth ods and instruments. The Committee itself is composed of a cross-section of school person nel from teachers to assistant superintendents. Questionnaire techniques have been and are be ing continuously used to determine the needs and attitudes of the large number of individuals, who, for obvious practical reasons, cannot participate as members of the Committee. It is as an as pect of the participatory process that this list of annotations will be of value if the easier loca tion of pertinent source material is made pos sible for persons busy with other important ed ucational activities. In terms of function, it was desirable that the bibliography be extensive in the sense that it cover all material directly related to teacher evaluation; it was not necessary that it be so ex tensive as to cover all publications having a bearing on related topics. For example, many articles on the merit-type salary issue contain information pertinent to teacher evaluation, and these are included, even though the merit-type I salary philosophy has been rejected by the Com mittee. On the other hand, articles focused on salary schedule problems not relating to teach er evaluation are not included, nor are publica tions in the field of teacher competency unrelat ed to evaluation. As to the span of years to be covered, the publication in 1950 of a comprehensive bibliog raphy of teacher competence by Domas and Tied eman** made it unnecessary to include articles published prior to May of 1949, the last month covered in that work, which contains complete listings in the area of teacher evaluation. Ac tually, all articles appearing during 1949 were checked for inclusion in that bibliography, and only those not covered by Domas and Tiedeman are included in the list to follow. An effort was made to investigate and annotate all relevant articles from that time through March, 1953.
Magnetic Resonance Imaging-DRAGON Score: 3-Month Outcome Prediction After Intravenous Thrombolysis for Anterior Circulation Stroke

Background and Purpose— The DRAGON score, which includes clinical and computed tomographic scan parameters, showed a high specificity to predict 3-month outcome in patients with acute ischemic stroke treated by intravenous tissue plasminogen activator. We adapted the score for patients undergoing MRI as the first-line diagnostic tool. Methods— We reviewed patients with consecutive anterior circulation ischemic stroke treated ⩽4.5 hour by intravenous tissue plasminogen activator between 2003 and 2012 in our center, where MRI is systematically implemented as first-line diagnostic work-up. We derived the MRI-DRAGON score keeping all clinical parameters of computed tomography-DRAGON (age, initial National Institutes of Health Stroke Scale and glucose level, prestroke handicap, onset to treatment time), and considering the following radiological variables: proximal middle cerebral artery occlusion on MR angiography instead of hyperdense middle cerebral artery sign, and diffusion-weighted imaging Alberta Stroke Program Early Computed Tomography Score (DWI ASPECTS) ⩽5 instead of early infarct signs on computed tomography. Poor 3-month outcome was defined as modified Rankin scale >2. We calculated c-statistics as a measure of predictive ability and performed an internal cross-validation. Results— Two hundred twenty-eight patients were included. Poor outcome was observed in 98 (43%) patients and was significantly associated with all parameters of the MRI-DRAGON score in multivariate analysis, except for onset to treatment time (nonsignificant trend). The c-statistic was 0.83 (95% confidence interval, 0.78–0.88) for poor outcome prediction. All patients with a MRI-DRAGON score ⩽2 (n=22) had a good outcome, whereas all patients with a score ≥8 (n=11) had a poor outcome. Conclusions— The MRI-DRAGON score is a simple tool to predict 3-month outcome in acute stroke patients screened by MRI then treated by intravenous tissue plasminogen activator and may help for therapeutic decision.
Lessons to Be Learned From Research on Peace Education in the Context of Intractable Conflict

Recent research on peace education entails important practical lessons about educational work in regions of intractable conflict. Peace education in this context must deal with collective narratives and deeply rooted historical memories and societal beliefs. Research findings from a series of studies with Israeli and Palestinian students and teachers demonstrate the challenges of attaining durable and worthwhile effects through educational activities: short-term benefits may erode over time, ongoing violence and hostility may block attempts to understand the opponent's perspective, and power and status asymmetries may dictate incompatible agendas or prohibit a mutual common ground for constructive interaction. At the same time, these studies offer several promising directions to enhance the potential of carefully designed peace education programs. Such programs are likely to foster participants' ability to acknowledge the adversary's collective narrative, engage in constructive negotiations over issues of national identity, and express a less monolithic outlook of the conflict.
Identification of a Novel Cellular Transcriptional Repressor Interacting with the Latent Nuclear Antigen of Kaposi's Sarcoma-Associated Herpesvirus

ABSTRACT The latent nuclear antigen (LNA) of Kaposi's sarcoma-associated herpesvirus (KSHV) has an essential role in viral latent infection. LNA maintains the stability of KSHV episomes and modulates the expression of cellular genes. A novel cellular protein KLIP1 was identified to interact with LNA through yeast two-hybrid screening, and confirmed by a glutathione S-transferase pull down assay. Domain mapping showed that KLIP1 interacted with the N-terminal domain of LNA. Northern blot hybridization with a KLIP1 probe identified a major transcript of 1.8 kb and a minor transcript of 2.8 kb. cDNA library screening and 5′-RACE revealed that the major transcript encoded an open-reading-frame of 1,257 bp and had a 5′-untranslated region of 73 nucleotides. The major KLIP1 transcript was ubiquitously present in different cell types examined. A KLIP1 synthetic peptide antibody detected a doublet of 58-kDa and 63-kDa proteins in a Western blot assay. KLIP1 had two putative nuclear localization signals and showed punctate nuclear localization when expressed as a GFP-fusion protein. KLIP1 interacted with LNA in vivo, as demonstrated by coimmunoprecipitation using KSHV-infected cells and colocalization when they were expressed as GFP- and DsRed-fusion proteins, respectively. Consistent with its interaction with LNA, nuclear localization, and possession of two leucine zipper motifs, KLIP1 behaved like a transcriptional factor and repressed herpes simplex virus thymidine kinase (TK) promoter activity in a mammalian one-hybrid assay. In addition, cotransfection with LNA alleviated the transcriptional repression effect of KLIP1 on TK promoter activity. These results suggest that KLIP1 is a new member of cellular transcriptional repressors, and that LNA is involved in deregulating cellular transcription process.
Implementing centralised IT service management: drawing lessons from the public sector

[Abstract]: The IT service management model represents a paradigm shift for IT organisations as it deemphasizes the management of IT assets and focuses on the provision of quality end-to-end IT services. This paper presents part of an in-depth study that examines the experience of a government agency, Queensland Health, in the implementation of a centralised IT service management model based on the ITIL framework. The paper sheds light on the challenges and breakthroughs, distils a set of critical success factors and offers a learning opportunity for other organisations. Outsourcing some activities and tool requirements to vendors was seen as one contributor to success although ensuring effective technology transfer to in-house staff was also necessary. Another success factor was centralisation of IT services. Commitment of senior management was also crucial as was a recognition of the need for effective change management to transform the organisational culture to a service-oriented focus.
Adapting WSJ-Trained Parsers to the British National Corpus using In-Domain Self-Training

We introduce a set of 1,000 gold standard parse trees for the British National Corpus (BNC) and perform a series of self-training experiments with Charniak and Johnson's reranking parser and BNC sentences. We show that retraining this parser with a combination of one million BNC parse trees (produced by the same parser) and the original WSJ training data yields improvements of 0.4% on WSJ Section 23 and 1.7% on the new BNC gold standard set.
Three-dimensional porous coordination polymer functionalized with amide groups based on tridentate ligand: selective sorption and catalysis.

To create a functionalized porous compound, amide group is used in porous framework to produce attractive interactions with guest molecules. To avoid hydrogen-bond formation between these amide groups our strategy was to build a three-dimensional (3D) coordination network using a tridentate amide ligand as the three-connector part. From Cd(NO3)2.4H2O and a three-connector ligand with amide groups a 3D porous coordination polymer (PCP) based on octahedral Cd(II) centers, {[Cd(4-btapa)2(NO3)2]. 6H2O.2DMF}n (1a), was obtained (4-btapa = 1,3,5-benzene tricarboxylic acid tris[N-(4-pyridyl)amide]). The amide groups, which act as guest interaction sites, occur on the surfaces of channels with dimensions of 4.7 x 7.3 A2. X-ray powder diffraction measurements showed that the desolvated compound (1b) selectively includes guests with a concurrent flexible structural (amorphous-to-crystalline) transformation. The highly ordered amide groups in the channels play an important role in the interaction with the guest molecules, which was confirmed by thermogravimetric analysis, adsorption/desorption measurements, and X-ray crystallography. We also performed a Knoevenagel condensation reaction catalyzed by 1a to demonstrate its selective heterogeneous base catalytic properties, which depend on the sizes of the reactants. The solid catalyst 1a maintains its crystalline framework after the reaction and is easily recycled.
Interactional Dynamics in Alcohol-Complicated Marital Relationships: A Study From India

This study seeks to understand differences in the interpersonal dynamics of couples living in alcohol-complicated and alcohol-free marital relationships in India. An ex-post facto cross-sectional design was used to compare 150 wives of alcoholics with an equal number of wives of nonalcoholics, who were administered standardized instruments to assess marital adjustment and family interaction pattern. Analyses show that wives of alcoholics have lower levels of marital adjustment and a poorer family interaction pattern across various domains, in consonance with the Western literature on these issues. Covariates analyzed included four variables such as type of family, type of marriage, consanguinity, and wife's occupational status. Implications for de-addiction programs in India are discussed and the need for couple/family-based therapy is emphasised.
Gamma Activation in Young People with Autism Spectrum Disorders and Typically-Developing Controls When Viewing Emotions on Faces

Background Behavioural studies have highlighted irregularities in recognition of facial affect in children and young people with autism spectrum disorders (ASDs). Recent findings from studies utilising electroencephalography (EEG) and magnetoencephalography (MEG) have identified abnormal activation and irregular maintenance of gamma (>30 Hz) range oscillations when ASD individuals attempt basic visual and auditory tasks. Methodology/Principal Fndings The pilot study reported here is the first study to use spatial filtering techniques in MEG to explore face processing in children with ASD. We set out to examine theoretical suggestions that gamma activation underlying face processing may be different in a group of children and young people with ASD (n = 13) compared to typically developing (TD) age, gender and IQ matched controls. Beamforming and virtual electrode techniques were used to assess spatially localised induced and evoked activity. While lower-band (3–30 Hz) responses to faces were similar between groups, the ASD gamma response in occipital areas was observed to be largely absent when viewing emotions on faces. Virtual electrode analysis indicated the presence of intact evoked responses but abnormal induced activity in ASD participants. Conclusions/Significance These findings lend weight to previous suggestions that specific components of the early visual response to emotional faces is abnormal in ASD. Elucidation of the nature and specificity of these findings is worthy of further research.
A DFA-Resistant and Masked PRESENT with Area Optimization for RFID Applications

Radio-Frequency Identification (RFID) tag-based applications are usually resource constrained and security sensitive. However, only about 2,000 gate equivalents in a tag can be budgeted for implementing security components [27]. This requires not only lightweight cryptographic algorithms such as PRESENT (around 1,000 gate equivalents) but also lightweight protections against modern Side Channel Attacks (SCAs). With this budget, the first-order masking and fault detection are two suitable countermeasures to be developed for PRESENT. However, if both countermeasures are applied without any optimization, it will significantly exceed the given area budget. In this work, we optimize area to include both countermeasures to maximize the security for PRESENT within this RFID area budget. The most area-consuming parts of the proposed design are the masked S-boxes and the inverse masked S-boxes. To optimize the area, we have deduced a computational relationship between these two parts, which enables us to reuse the hardware resource of the masked S-boxes to implement the inverse masked S-boxes. The proposed design takes up only 2,376 gates with UMC 65nm CMOS technology. Compared with the unoptimized design, our implementation reduces the overall area by 28.45%. We have tested the effectiveness of the first-order Differential Power Analysis (DPA) and Differential Fault Analysis (DFA) -resistant countermeasures. Experimental results show that we have enhanced the SCA resistance of our PRESENT implementation.
Extracurricular activities, positive youth development, and the role of meaningfulness of engagement

Previous research has shown that participation in extracurricular activities in high school can promote desirable outcomes, such as educational attainment and reduced problem behaviors, but little attention has been paid to relations with psychological indicators of positive youth development (PYD). Moreover, the potential importance of the degree to which young people find such engagement personally meaningful toward these relations has been overlooked. This study investigated longitudinal relations among extracurricular participation and multiple indicators of positive development in adolescence, and explored whether personal meaningfulness of these domains moderated these relations. Results showed that positive development was positively associated with participation in student leadership and volunteering, and negatively associated with participation in the creative arts. Additionally, many of the relations among extracurricular participation and positive development were moderated by activity meaningfulness, typically in the negative direction. The discussion highlights future directions for research on extracurricular participation, meaningful engagement, and PYD.
Tracking the effectiveness of usability evaluation methods

Abstract We present a case study that tracks usability problems predicted with six usability evaluation methods (claims analysis, cognitive walkthrough, GOMS, heuristic evaluation, user action notation, and simply reading the specification) through a development process. We assess the method's predictive power by comparing the predictions to the results of user tests. We assess the method's persuasive power by seeing how many problems led to changes in the implemented code. We assess design-change effectiveness by user testing the resulting new versions of the system. We concludethatpredictivemethodsarenot as effective as the HCI field would like and discuss directions for future research.
