Will Hypertension Performance Measures Used for Pay-for-Performance Programs Penalize Those Who Care for Medically Complex Patients?

Background— There is concern that performance measures, patient ratings of their care, and pay-for-performance programs may penalize healthcare providers of patients with multiple chronic coexisting conditions. We examined the impact of coexisting conditions on the quality of care for hypertension and patient perception of overall quality of their health care. Methods and Results— We classified 141 609 veterans with hypertension into 4 condition groups: those with hypertension-concordant (diabetes mellitus, ischemic heart disease, dyslipidemia) and/or -discordant (arthritis, depression, chronic obstructive pulmonary disease) conditions or neither. We measured blood pressure control at the index visit, overall good quality of care for hypertension, including a follow-up interval, and patient ratings of satisfaction with their care. Associations between condition type and number of coexisting conditions on receipt of overall good quality of care were assessed with logistic regression. The relationship between patient assessment and objective measures of quality was assessed. Of the cohort, 49.5% had concordant-only comorbidities, 8.7% had discordant-only comorbidities, 25.9% had both, and 16.0% had none. Odds of receiving overall good quality after adjustment for age were higher for those with concordant comorbidities (odds ratio, 1.78; 95% confidence interval, 1.70 to 1.87), discordant comorbidities (odds ratio, 1.32; 95% confidence interval, 1.23 to 1.41), or both (odds ratio, 2.25; 95% confidence interval, 2.13 to 2.38) compared with neither. Findings did not change after adjustment for illness severity and/or number of primary care and specialty care visits. Patient assessment of quality did not vary by the presence of coexisting conditions and was not related to objective ratings of quality of care. Conclusions— Contrary to expectations, patients with greater complexity had higher odds of receiving high-quality care for hypertension. Subjective ratings of care did not vary with the presence or absence of comorbid conditions. Our findings should be reassuring to those who care for the most medically complex patients and are concerned that they will be penalized by performance measures or patient ratings of their care.
Breast-feeding in South Korea: factors influencing its initiation and duration

Abstract Objective To investigate factors influencing the practices of partial breast-feeding (PBF) and exclusive breast-feeding (EBF). Design A national, cross-sectional survey was conducted among married women aged 15–49 years from May to August 2003. Setting South Korea. Subjects A total of 865 mothers answered questions regarding the feeding practices of their youngest baby, born between January 2001 and May 2003. Results The initiation rates of PBF and EBF were 81% and 63%, respectively. However, the median durations of PBF and EBF were very short: 12 and 8 weeks, respectively. According to stepwise logistic and Cox regression analyses, the more prenatal care women received, the more likely they were to initiate PBF and EBF but the less likely to continue EBF. Delivery by Caesarean section decreased the initiation of PBF and EBF. The mother’s education level and employment status before marriage, the amount of prenatal care, delivery method and baby’s status at birth affected breast-feeding initiation, whereas the amount of prenatal care influenced breast-feeding duration. Conclusion To promote breast-feeding, education and campaigning on the importance of continued breast-feeding should be provided to the general public, particularly to health workers in maternity units.
Roles for mitotic history in the generation and degeneration of hippocampal neuroarchitecture

The mechanisms regulating the highly ordered neuroarchitecture of the mammalian brain are largely unknown. The present study took advantage of hippocampal pyramidal-like neurons that arose from a common progenitor cell in cell culture (sister neurons) to ascertain the contribution of intrinsic factors to both the generation and degeneration of neuroarchitecture. Sister neurons were similar in overall cell form and dendritic numbers and lengths. Control non-sister neurons that grew in contact did not generate similar morphologies, indicating that the similarity of sister cells did not result from influences of the local microenvironment or cell interactions. These results suggest that intrinsic factors related to mitotic history play a role in the generation of neuroarchitecture. Since particular groups of hippocampal neurons are sensitive to glutamate neurotoxicity in situ and are vulnerable in neurodegenerative disorders, it was of interest to test glutamate sensitivity in the neuronal population and in mitotic sister neurons. A subpopulation of pyramidal neurons was sensitive to glutamate neurotoxicity. A striking finding was that sister neurons were invariably either both sensitive or both resistant to glutamate, while non-sister neurons often showed different responses to glutamate. Pharmacological studies indicated that glutamate neurotoxicity was mediated by kainate/quisqualate type receptors by a mechanism involving calcium influx through membrane channels. Fura-2 measurements of intracellular calcium revealed that sister neurons had similar rest levels of calcium and, strikingly, glutamate caused a dramatic increase in intracellular calcium levels only in neurons which subsequently degenerated. Apparently, intrinsic differences in sensitivity to glutamate lie at a point prior to calcium entry, probably at the level of glutamate receptors. Taken together, these results indicate that the mitotic history of a neuron can determine its presence and potential for connectivity as well as its susceptibility to neurodegeneration.
Classroom Assessment for Learning.

Imagine classroom assessment as a healthy part of effective teaching and successful learning. At a time when large-scale, external assessments of learning gain political favor and attention, many teachers are discovering how to engage and motivate students using day-to-day classroom assessment for purposes beyond measurement. By applying the principles of what is called assessment for learning, teachers have followed clear research findings of the effects that high-quality, formative assessment can have on student achievement. We typically think of assessment as an index of school success rather than as the cause of that success. Unfortunately, largely absent from the traditional classroom assessment environment is the use of assessment as a tool to promote greater student achievement (Shepard, 2000). In general, the teacher teaches and then tests. The teacher and class move on, leaving unsuccessful students, those who might not learn at the established pace and within a fixed time frame, to finish low in the rank order. This assessment model is founded on two outdated beliefs: that to increase learning we should increase student anxiety and that comparison with more successful peers will motivate low performers to do better. By contrast, assessment for learning occurs during the teaching and learning process rather than after it and has as its primary focus the ongoing improvement of learning for all students (Assessment Reform Group, 1999; Crooks, 2001; Shepard, 2000). Teachers who assess for learning use day-to-day classroom assessment activities to involve students directly and deeply in their own learning, increasing their confidence and motivation to learn by emphasizing progress and achievement rather than failure and defeat (Stiggins, 1999; 2001). In the assessment for learning model, assessment is an instructional tool that promotes learning rather than an event designed solely for the purpose of evaluation and assigning grades. And when students become involved in the assessment process, assessment for learning begins to look more like teaching and less like testing (Davies, 2000).
A central role for DOCK2 during interstitial lymphocyte motility and sphingosine-1-phosphate–mediated egress

Recent observations using multiphoton intravital microscopy (MP-IVM) have uncovered an unexpectedly high lymphocyte motility within peripheral lymph nodes (PLNs). Lymphocyte-expressed intracellular signaling molecules governing interstitial movement remain largely unknown. Here, we used MP-IVM of murine PLNs to examine interstitial motility of lymphocytes lacking the Rac guanine exchange factor DOCK2 and phosphoinositide-3-kinase (PI3K)γ, signaling molecules that act downstream of G protein–coupled receptors, including chemokine receptors (CKRs). T and B cells lacking DOCK2 alone or DOCK2 and PI3Kγ displayed markedly reduced motility inside T cell area and B cell follicle, respectively. Lack of PI3Kγ alone had no effect on migration velocity but resulted in increased turning angles of T cells. As lymphocyte egress from PLNs requires the sphingosine-1-phosphate (S1P) receptor 1, a Gαi protein–coupled receptor similar to CKR, we further analyzed whether DOCK2 and PI3Kγ contributed to S1P-triggered signaling events. S1P-induced cell migration was significantly reduced in T and B cells lacking DOCK2, whereas T cell–expressed PI3Kγ contributed to F-actin polymerization and protein kinase B phosphorylation but not migration. These findings correlated with delayed lymphocyte egress from PLNs in the absence of DOCK2 but not PI3Kγ, and a markedly reduced cell motility of DOCK2-deficient T cells in close proximity to efferent lymphatic vessels. In summary, our data support a central role for DOCK2, and to a lesser extent T cell–expressed PI3Kγ, for signal transduction during interstitial lymphocyte migration and S1P-mediated egress.
Association of tenascin‐W expression with mineralization in mouse calvarial development

Tenascin‐W is a tenascin family member that forms part of a complex extracellular matrix, and previous studies have suggested its association with osteogenesis. In the present study we investigated the roles of tenascin‐W in osteogenesis. We found that tenascin‐W is expressed in osteoblasts at the edge of the developing bone domain prior to mineralization in mouse fetuses. Expression of tenascin‐W was induced during the course of mineralization of the Kusa‐A1 osteoblast cell line. In the interfrontal suture of postnatal mice, the anterior portion remains patent and the posterior portion closes by 4 weeks of age. Tenascin‐W expression was downregulated at 1 week of age in the posterior frontal suture, whereas in the anterior suture, expression was maintained until the mice reached 4 weeks of age. Fibroblast growth factor 2 (FGF2)‐bead application to the mouse fetal skull by ex‐utero surgery accelerated osteoblast differentiation, but inhibited mineralization with a downregulation of tenascin‐W expression. These results suggest that tenascin‐W is involved in osteoblast maturation (i.e. mineralization).
An online people counting system for electronic advertising machines

This paper presents a novel people counting system for an environment in which a stationary camera can count the number of people watching a TV-wall advertisement or an electronic billboard without counting the repetitions in video streams in real time. The people actually watching an advertisement are identified via frontal face detection techniques. To count the number of people precisely, a complementary set of features is extracted from the torso of a human subject, as that part of the body contains relatively richer information than the face. In addition, for conducting robust people recognition, an online classifier trained by Fisher's Linear Discriminant (FLD) strategy is developed. Our experiment results demonstrate the efficacy of the proposed system for the people counting task.
Radar Signatures of a Passenger Car

Upcoming new synthetic aperture radar (SAR) satellites such as TerraSAR-X and Radarsat-2 offer high spatial image resolution and dual receive antenna capabilities, which open new opportunities for worldwide traffic monitoring applications. If the radar cross section (RCS) of the vehicles is strong enough, they can be detected in the SAR data, and their speed can be measured. For system performance prediction and algorithm development, it is therefore indispensable to know the RCS of typical passenger cars. The geometry parameters that have to be considered are the radar look direction, incidence angle, and vehicle orientation. In this letter, the radar signatures of nonmoving or parking cars are presented. They are measured experimentally from airborne experimental SAR (E-SAR) data, which have been collected during flight campaigns in 2005 and 2006 with multiple overflights at different aircraft headings. The radar signatures could be measured for the whole range of aspect angles from 0 to 180 and with high angular resolution due to the large synthetic aperture length of the E-SAR radar sensor. The analysis for one type of passenger car and particular incidence angles showed that the largest radar cross-sectional values and, thus, the greatest chance of detection of the vehicles appear when the car is seen from the front, back, and side. Radar cross-sectional values for slanted views are much lower and are therefore less suitable for car detection. The measurements have been performed in the -band (9.6 GHz) with VV-polarization, and at incidence angles of 41.5deg and 42.5deg. The derived radar signature profile can also be used for the verification of radar cross-sectional simulation studies.
The Effectiveness of a Learning Strategies Course on College Student-Athletes' and Non-Athletes' Adjustment, Academic Performance, and Retention after the First Two Years of College

This study replicated and extended previous research I had performed that suggested that a student success course is an effective intervention to assist student-athletes in the adjustment to college. Participants in the current study included 4 groups of students, including (1) non-athletes and (2) student-athletes who were mandated and enrolled in the student success course, and (3) non-athletes and (4) student-athletes who were not mandated and did not enroll in the student success course. Overall, results from the current study suggested that the student success course was effective in helping non-athletes and student-athletes learn key cognitive strategies that are necessary for college success. In addition, results indicated that after taking the student success course, academically at-risk students earned equivalent grades, percentage of hours passed, and retention rates compared to their peers who were not classified as being academically underprepared. Finally, adjustment patterns of all groups were examined, with particular emphasis on the decrease in adjustment over the course of the semester that was demonstrated by the student-athletes. Intervention implications and future research directions are discussed, specifically in terms of how to address the unique needs of college freshmen student-athletes.
ONLINE JOURNALISM AND THE PROMISES OF NEW TECHNOLOGY

Research about online journalism has been dominated by a discourse of technological innovation. The “success” of online journalism is often measured by the extent to which it utilizes technological assets like interactivity, multimedia and hypertext. This paper critically examines the technologically oriented research about online journalism in the second decade of its existence. The aim is twofold. First, to investigate to what degree online journalism, as it is portrayed in empirical research, utilizes new technology more than previously. Second, the paper points to the limitations of technologically oriented research and suggests alternative research approaches that might be more effective in explaining why online journalism develops as it does.
Designing Medical and Educational Intervention Studies: A review of some alternatives to conventional randomized controlled trials

The advantages and limitations of RCT designs are discussed, and a range of alternative designs for medical and educational intervention studies considered. Designs selected are those that address the much neglected psychological issues involved in the recruitment of patients and allocation of patients to treatments within trials. Designs include Zelen's (18) randomized consent design, Brewin and Bradley's (20) partially randomized patient-centered design, and Korn and Baumrind's (21) partially randomized clinician-centered design. The possibilities of combining features from each of the last two designs are illustrated, and the advantages of adopting a more flexible and clinically relevant approach to the design of clinical trials are discussed.
Online game QoE evaluation using paired comparisons

To satisfy players' gaming experience, there is a strong need for a technique that can measure a game's quality systematically, efficiently, and reliably. In this paper, we propose to use paired comparisons and probabilistic choice models to quantify online games' QoE under various network situations. The advantages of our methodology over the traditional MOS ratings are 1) the rating procedure is simpler thus less burden is on experiment participants, 2) it derives ratio-scale scores, and 3) it enables systematic verification of participants' inputs. As a demonstration, we apply our methodology to evaluate three popular FPS (first-person-shooter) games, namely, Alien Arena (Alien), Halo, and Unreal Tournament (UT), and investigate their network robustness. The results indicate that Halo performs the best in terms of their network robustness against packet delay and loss. However, if we take the degree of the games' sophistication into account, we consider that the robustness of UT against downlink delays should able be improved. We also show that our methodology can be a helpful tool for making decisions about design alternatives, such as how dead reckoning algorithms and time synchronization mechanisms should be implemented.
The Compliment Responses Used by Herbalife's Male and Female Customers in Surabaya

This journal mainly deals with the males’ and females’ compliment responses from Herbalife following up system. The focus of my analysis is the types of the males’ and females’ compliment responses that occurred most frequently by both genders, the differences or/and similarities of males’ and females’ compliment responses types. To analyze the data, I used Holmes’ (1995&2006) and Wolfson’s (1989) theories. I used Lesmana’s research (2009) as well the contrast between an online communication research and an offline communication research as supporting thesis. For the methods, I used a descriptive qualitative approach to be supported by quantitative data in developing my research.Then, from my analysis, I found that the both male and female interlocutors tended to accept the compliments given by me as the female complimenter.
Contrats Incitatifs et Réforme des Douanes dans les PED: une Application des Modèles d’Agence Hiérarchique

Dans de nombreux pays en voie de developpement, des Programmes de Verification des Importations (PVI) ont ete instaures pour combattre la corruption des administrations douanieres. Ils consistent a deleguer l’inspection des importations a une entreprise privee qui opere dans les pays exportateurs. De tels programmes s’averent particulierement couteux car l’entreprise se paye generalement entre 0,5% et 0,8% de la valeur FOB des marchandises inspectees. Dans cet article, nous analysons l’efficacite de ces programmes a la lumiere de la theorie de l’agence. Plus precisement, nous utilisons le modele d’agence hierarchique afin d’apprehender les interactions entre le gouvernement, l’administration douaniere, l’importateur et l’entreprise assurant le PVI. De cette analyse nous deduisons quelques recommandations qui concernent entre autres l’identite des contractants, la modernisation des administrations douanieres ou la politique de reconciliation.
Association Between Ball-Handling Versus Defending Actions and Acute Noncontact Lower Extremity Injuries in High School Basketball and Soccer

Background: High school–sponsored athletic programs currently provide more than 7.7 million students in the United States with health and societal benefits, but they also inherently increase the risk of students sustaining a sports injury. Understanding risk factors that predict injuries in sports is an essential first step to addressing the problem in this population. Purpose: To determine the role of offensive versus defensive actions in noncontact lower extremity injury rates in high school basketball and soccer in both boys’ and girls’ sports. Study Design: Descriptive epidemiological study. Methods: Noncontact lower extremity injury data were collected from academic years 2005-2006 through 2011-2012 for boys’ and girls’ basketball and soccer through the surveillance tool High School RIO (reporting information online). The injuries in this subset of the database occurred over a total of 6.4 million athlete-exposures. Results: Significant differences in overall lower extremity injury rates were found when comparing ball-handling and defending actions in basketball (rate ratio [RR], 1.36; 95% CI, 1.08-1.73; P = .009), but no appreciable difference was observed in soccer (RR, 0.89; 95% CI, 0.70-1.12; P = .31). Female participants had higher injury rates than did males for both ball-handling and defending actions for both sports (P < .05). Only girls’ soccer showed significant differences in the odds ratio (OR) of defending to ball-handling injury rates between competition and practice (OR, 1.88; 95% CI, 1.01-3.48; P = .047). Conclusion: The injury rate differences observed in this study between offensive and defensive actions suggest that investigating potential differences between sport-specific tasks may provide a more complete understanding of injury mechanisms.
A Peaceful Clash: The U.S. And China: Which Model Holds Out Promise For The Future?

This article analyzes some prospects for the economic and political development of the United States and China. The first part of the article is devoted to the consideration of strengths and weaknesses of the U.S. model and of the Chinese one. The second part of the article considers the most probable scenarios of the future struggle for world leadership. The first scenario suggests that China will continue developing at a faster rate in the several coming decades and will be gradually catching up with the United States in terms of Gross Domestic Product (GDP) production. However, after several crises in 2008–2020 the United States will likely regain a number of advantages over China as a result of assimilation of the newest technologies. The second scenario suggests that the United States will come across a whole range of internal social and political problems related to internal political splits. In this case, the United States will have to share its global leadership with China. The article attempts to answer the following questions: What scenario is more probable? Will the old world order change? What are the main conclusions for the European Union and for Russia?
