Characteristics of pollutants and their correlation to meteorological conditions at a suburban site in the North China Plain

Abstract. North China Plain (NCP) is one of the most densely populated regions in China and has experienced enormous economic growth in the past decades. Its regional trace gas pollution has also become one of the top environmental concerns in China. Measurements of surface trace gases, including O 3 , NO x , SO 2 and CO were carried out within the HaChi (Haze in China) project at Wuqing Meteorology Station, located between 2 mega-cities (Beijing and Tianjin) in the NCP, from 9 July 2009 to 21 January 2010. Detailed statistical analyses were made in order to provide information on the levels of the measured air pollutants and their characteristics. Gaseous air pollutant concentrations were also studied together with meteorological data and satellite data to help us better understand the causes of the observed variations in the trace gases during the field campaign. In comparison to measurements from other rural and background stations in the NCP, relatively high concentrations were detected in Wuqing, presumably due to regional mixing and transport of pollutants. Local meteorology had deterministic impacts on air pollution levels, which have to be accounted for when evaluating other effects on pollutant concentrations. Trace gas concentrations showed strong dependence on wind, providing information on regional pollution characteristics. O 3 mixing ratio also showed clear dependencies on temperature and relative humidity.
Developing Rhythm in Teaching: The Narrative Study of a Beginning Teacher's Personal Practical Knowledge of Classrooms

ABSTRACTThis article explores the development of one novice teacher's personal practical knowledge during his first year of teaching. The work offers an account of personal practical knowledge, particularly of image, as nonpropositional in character; as having experiential origins and as having emotional and moral dimensions. The article analyzes the dilemmas that were created when one of the novice teacher's images, in its practical expressions, conflicted with the cyclic ordering of school time. Through the analysis we see a reconstruction of the novice's experience in a process of growth and change in his rhythmic knowledge of teaching. The article makes recommendations for programs of teacher education that allow for the reflective reconstruction of novices' narratives of experience.
Distributed Coloring with Õ ( √ log n ) Bits ∗

We consider the well-known vertex coloring problem: given a graph G, find a coloring of its vertices so that no two neighbors in G have the same color. It is trivial to see that every graph of maximum degree ∆ can be colored with ∆ + 1 colors, and distributed algorithms that find a (∆ + 1)-coloring in a logarithmic number of communication rounds, with high probability, are known since more than a decade. This is in general the best possible if only a constant number of bits can be sent along every edge in each round. In fact, we show that for the n-node cycle the bit complexity of the coloring problem is Ω(log n). More precisely, if only one bit can be sent along each edge in a round, then every distributed coloring algorithm (i.e., algorithms in which every node has the same initial state and initially only knows its own edges) needs at least Ω(log n) rounds, with high probability, to color the n–node cycle, for any finite number of colors. But what if the edges have orientations, i.e., the endpoints of an edge agree on its orientation (while bits may still flow in both directions)? Edge orientations naturally occur in dynamic networks where new nodes establish connections to old nodes. Does this allow one to provide faster coloring algorithms? Interestingly, for the n–node cycle in which all edges have the same orientation, we show that a simple randomized algorithm can achieve a 3-coloring with only O( √ log n) rounds of bit transmissions, with high probability (w.h.p.). This result is tight because we also show that the bit complexity of coloring an n–node oriented cycle is Ω( √ log n), with high probability, no matter how many colors are allowed. The 3-coloring algorithm can be easily extended to provide a (∆ + 1)-coloring for all graphs of maximum degree ∆ in O( √ log n) rounds of bit transmissions, w.h. p., if ∆ is a constant, the edges are oriented, and the graph does not contain an oriented cycle of length less than √ log n. Using more complex algorithms, we show how to obtain an O(∆)-coloring for arbitrary oriented graphs of maximum degree ∆ using essentially O(log ∆+ √ log n) rounds of bit transmissions, w.h. p., provided that the graph does not contain an oriented cycle of length less than √ log n. A preliminary version of the results contained in this paper appeared in the IEEE Internation Parallel and Distributed Processing Symposium (IPDPS), 2006 [18].

Essential Role of CD11a in CD8+ T-Cell Accumulation and Activation in Adipose Tissue

Objective— T cells, particularly CD8+ T cells, are major participants in obesity-linked adipose tissue (AT) inflammation. We examined the mechanisms of CD8+ T-cell accumulation and activation in AT and the role of CD11a, a &bgr;2 integrin. Approach and Results— CD8+ T cells in AT of obese mice showed activated phenotypes with increased proliferation and interferon-&ggr; expression. In vitro, CD8+ T cells from mouse AT displayed increased interferon-&ggr; expression and proliferation to stimulation with interleukin-12 and interleukin-18, which were increased in obese AT. CD11a was upregulated in CD8+ T cells in obese mice. Ablation of CD11a in obese mice dramatically reduced T-cell accumulation, activation, and proliferation in AT. Adoptive transfer showed that CD8+ T cells from wild-type mice, but not from CD11a-deficient mice, infiltrated into AT of recipient obese wild-type mice. CD11a deficiency also reduced tumor necrosis factor-&agr;–producing and interleukin-12–producing macrophages in AT and improved insulin resistance. Conclusions— Combined action of cytokines in obese AT induces proliferative response of CD8+ T cells locally, which, along with increased infiltration, contributes to CD8+ T-cell accumulation and activation in AT. CD11a plays a crucial role in AT inflammation by participating in T-cell infiltration and activation.
Homework Emotion Regulation Scale: Confirming the Factor Structure With High School Students

The current investigation studied psychometric properties of the Homework Emotion Regulation Scale (HERS) for math homework, with 915 tenth graders from China. Confirmatory factor analyses (CFAs) supported the presence of two separate yet related subscales for the HERS: Emotion Management and Cognitive Reappraisal. The latent factor means for both subscales were shown to be invariant across gender. Furthermore, both subscales were positively related to homework purposes and behaviors (effort and completion) in the theoretically expected directions. Meanwhile, math performance was positively related to emotion management, but not cognitive reappraisal.
Increasing time to operation is associated with decreased survival in patients with a positive FAST examination requiring emergent laparotomy

INTRODUCTION Focused assessment with sonography for trauma (FAST) is commonly used to facilitate the timely diagnosis of life-threatening hemorrhage in injured patients. Most patients with positive findings on FAST require laparotomy. Although it is assumed that an increasing time to operation (T-OR) leads to higher mortality, this relationship has not been quantified. This study sought to determine the impact of T-OR on survival in patients with a positive FAST who required emergent laparotomy. METHODS We retrospectively analyzed patients from the PRospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study who underwent laparotomy within 90 minutes of presentation and had a FAST performed. Cox proportional hazards models including Injury Severity Score (ISS), age, base deficit, and hospital site were created to examine the impact of increasing T-OR on in-hospital survival at 24 hours and 30 days. The impact of time from the performance of the FAST examination to operation (TFAST-OR) on in-hospital mortality was also examined using the same model. RESULTS One hundred fifteen patients met study criteria and had complete data. Increasing T-OR was associated with increased in-hospital mortality at 24 hours (hazard ratio [HR], 1.50 for each 10-minute increase in T-OR; confidence interval [CI], 1.14–1.97; p = 0.003) and 30 days (HR, 1.41; CI, 1.18–2.10; p = 0.002). Increasing TFAST-OR was also associated with higher in-hospital mortality at 24 hours (HR, 1.34; CI, 1.03–1.72; p = 0.03) and 30 days (HR, 1.40; CI, 1.06–1.84; p = 0.02). CONCLUSION In patients with a positive FAST who required emergent laparotomy, delay in operation was associated with increased early and late in-hospital mortality. Delays in T-OR in trauma patients with a positive FAST should be minimized. LEVEL OF EVIDENCE Epidemiologic/prognostic study, level IV.
The initiation of a multidisciplinary bladder cancer clinic and the uptake of neoadjuvant chemotherapy: A time-series analysis.

INTRODUCTION While level 1 evidence supports the use of neoadjuvant chemotherapy (NAC) for patients with muscle-invasive bladder cancer (MIBC), its uptake has been underwhelming, even in academic centres. Our aim was to determine if the initiation of a multidisciplinary bladder cancer clinic (MDBCC) in 2008 at our institution, where patients are assessed simultaneously by bladder cancer-focused urologists and radiation oncologists with easy access to a medical oncologist, was associated with an increased use of NAC. METHODS Patients with MIBC initiating treatment between July 2000 and June 2013 were identified and classified by academic year (July 1 to June 30). Time-series analyses using interventional autoregressive integrated moving average (ARIMA) models with ramp intervention functions were then conducted. A sensitivity analysis was performed on clinical N0 patients. RESULTS The cohort included 278 patients: 168 from 2000-2007 and 110 from 2008-2012 (academic years). Forty-two (15.1%) patients received NAC and 74 (26.6%) received adjuvant chemotherapy (AC). Overall the proportion of patients receiving NAC increased from 7.7% before the MDBCC to 47.6% in 2012 (Interventional ARIMA p=0.036). The results were similar when restricting to cN0 patients (p<0.001). NAC use gradually increased over time regardless of MDBCC attendance, although the proportion of patients receiving NAC appears to have risen more sharply among MDBCC attendees. CONCLUSIONS At our institution, the initiation of the MDBCC was temporally associated with increased use of NAC. In addition to multidisciplinary collaboration, having a critical mass of NAC physician advocates and support from institutional leaders are essential to the uptake of NAC.
Student attitudes to undergraduate interprofessional education

Interprofessional education in health care has been the focus of increasing attention in recent years. However, there is still great debate about when and how to introduce it in undergraduate studies. St George’s Hospital Medical School with the Joint Faculty of Health Care Sciences of Kingston University was ideally placed to introduce, as part of its 1996 new curriculum, a Common Foundation Programme (CFP). This incorporated degree students in medicine, radiography, physiotherapy, and nursing learning together for the first term of their courses. As part of the evaluation of the CFP, students’ attitudes to the course and each other were surveyed at the beginning and the end of the term, for the 1998 and 1999 intakes. The results showed that students arrive at university with stereotyped views of each other, and that these views appeared to become more exaggerated during the CFP. Students felt that the CFP would enhance interprofessional working, but there were concerns that it forced them to learn irrelevant skills. Students whose parents worked as health care professionals, held stronger stereotyped views. Our findings challenge any notion that students arrive without preconceived ideas about the other professions. Further work is needed to appropriate models for interprofessional education, to enable graduates to work effectively in today’s environment.
Blockade of the Tonic Hindlimb Extensor Component of Maximal Electroshock and Pentylenetetrazol‐Induced Seizures by Drugs Acting on Muscle and Muscle Spindle Systems: A Perspective on Method

Blockade of tonic hindlimb extension (THE) in the maximal electroshock seizure test was demonstrated for C‐28 ‘882‐Ba, a muscle spindle suppressant, chlorpromazine, a depressant of fusimotor drive, and gallamine, a neuromuscular blocking drug. These agents also blocked THE produced by very large doses of pentylenetetrazol. Dantrolene, a muscle contraction antagonist, and MI‐65‐S, a muscle spindle suppressant, significantly delayed THE. The data indicate that blockade of THE may be effected at a multiplicity of loci and may not be an expression of an “anticonvulsant” effect.
Laryngeal complications after thyroidectomy: is it always the surgeon?

HYPOTHESIS Laryngeal dysfunction after thyroidectomy is a common complication. However, few data are available to differentiate whether these complications result from injury to the recurrent nerve or to the vocal folds from intubation. SETTING University medical center. PATIENTS Seven hundred sixty-one patients who underwent surgery to the thyroid gland from 1990 to 2002. Of these patients, 8.4% underwent a revision thyroidectomy. INTERVENTION Preoperative and postoperative laryngostroboscopic examination. MAIN OUTCOME MEASURE Laryngostroboscopic evaluation of laryngeal complications. RESULTS The overall rate of laryngeal complications was 42.0% (320 patients). Complications from an injury to the vocal folds occurred in 31.3% of patients. Weakness or paresis of the recurrent nerve was initially present in 6.6% and was related to the nerves at risk. This rate was higher in revision thyroidectomies than in primary surgical interventions (6.2% vs 11.6%; P = .04). The rate of laryngeal injuries was higher in patients older than 65 years (39.8% vs 30.8%; P = .03). CONCLUSIONS These data suggest that laryngeal complications after thyroidectomies are primarily caused by injury to the vocal folds from intubation and to a lesser extent by injury to the laryngeal nerve. We recommend documentation of informed consent, especially for patients who use their voice professionally, such as singers, actors, or teachers.
Investigation of under-ascertainment in epidemiological studies based in general practice.

BACKGROUND One of the aims of the Study of Infectious Intestinal Disease (IID) in England is to estimate the incidence of IID presenting to general practice. This sub-study aims to estimate and correct the degree of under-ascertainment in the national study. METHODS Cases of presumed IID which presented to general practice in the national study had been ascertained by their GP. In 26 general practices, cases with computerized diagnoses suggestive of IID were identified retrospectively. Cases which fulfilled the case definition of IID and should have been ascertained to the coordinating centre but were not, represented the under-ascertainment. Logistic regression modelling was used to identify independent factors which influenced under-ascertainment. RESULTS The records of 2021 patients were examined, 1514 were eligible and should have been ascertained but only 974 (64%) were. There was variation in ascertainment between the practices (30% to 93%). Patient-related factors independently associated with ascertainment were: i) vomiting only as opposed to diarrhoea with and without vomiting (OR 0.37) and ii) consultation in the surgery as opposed to at home (OR 2.18). Practice-related factors independently associated with ascertainment were: i) participation in the enumeration study component (OR 1.78), ii) a larger number of partners (OR 0.3 for 7-8 partners); iii) rural location (OR 2.27) and iv) previous research experience (OR 1.92). Predicted ascertainment percentages were calculated according to practice characteristics. CONCLUSION Under-ascertainment of IID was substantial (36%) and non-random and had to be corrected. Practice characteristics influencing variation in ascertainment were identified and a multivariate model developed to identify adjustment factors which could be applied to individual practices. Researchers need to be aware of factors which influence ascertainment in acute epidemiological studies based in general practice.
Potential for Pet Animals to Harbour Methicillin‐Resistant Staphylococcus aureus When Residing with Human MRSA Patients

Colonization by methicillin‐resistant Staphylococcus aureus (MRSA) may be persistent in people and is horizontally transmissible. The scientific literature suggests that domestic pets may also participate in cross‐transmission of MRSA within households. The objectives of this study were to evaluate the prevalence of and risk factors for MRSA carriage by pets residing in households with an MRSA‐infected person. From 66 households in which an MRSA‐infected patient resided, we screened 47 dogs and 52 cats using a swab protocol. Isolates from pets and humans were genotyped using two techniques and compared for concordance. Human participants completed a 22‐question survey of demographic and epidemiologic data relevant to staphylococcal transmission. Eleven of 99 pets (11.5%) representing 9 (13.6%) of households were MRSA‐positive, but in only six of these households were the human and animal‐source strains genetically concordant. Human infection by strain USA 100 was significantly associated with pet carriage [OR = 11.4 (95% CI 1.7, 76.9); P = 0.013]. Yet, for each day of delay in sampling the pet after the person’s MRSA diagnosis, the odds of isolating any type of MRSA from the pet decreased by 13.9% [(95% CI 2.6, 23.8); P = 0.017)]. It may be concluded that pets can harbour pandemic strains of MRSA while residing in a household with an infected person. However, the source of MRSA to the pet cannot always be attributed to the human patient. Moreover, the rapid attrition of the odds of obtaining a positive culture from pets over time suggests that MRSA carriage may be fleeting.
Key is a llave is a Schlüssel: A failure to replicate an experiment from Boroditsky et al. 2003

Abstract In this paper, we present two attempts to replicate a widely-cited but never fully published experiment in which German and Spanish speakers were asked to associate adjectives with nouns of masculine and feminine grammatical gender (Boroditsky et al. 2003). The researchers claim that speakers associated more stereotypically female adjectives with grammatically feminine nouns and more stereotypically male adjectives with grammatically masculine nouns. We were not able to replicate the results either in a word association task or in an analogous primed lexical decision task. This suggests that the results of the original experiment were either an artifact of some non-documented aspect of the experimental procedure or a statistical fluke. The question whether speakers assign sex-based interpretations to grammatical gender categories at all cannot be answered definitively, as the results in the published literature vary considerably. However, our experiments show that if such an effect exists, it is not strong enough to be measured indirectly via the priming of adjectives by nouns.
Morbidity Among HIV-1-Infected Mothers in Kenya: Prevalence and Correlates of Illness During 2-Year Postpartum Follow-Up

Background:Much of the burden of morbidity affecting women of childbearing age in sub-Saharan Africa occurs in the context of HIV-1 infection. Understanding patterns of illness and determinants of disease in HIV-1-infected mothers may guide effective interventions to improve maternal health in this setting. Methods:We describe the incidence and cofactors of comorbidities affecting peripartum and postpartum HIV-1-infected women in Kenya. Women were evaluated by clinical examination and standardized questionnaires during pregnancy and for up to 2 years after delivery. Results:Five hundred thirty-five women were enrolled in the cohort (median CD4 count of 433 cells/mm3) and accrued 7736 person-months of follow-up. During 1-year follow-up, the incidence of upper respiratory tract infections was 161 per 100 person-years, incidence of pneumonia was 33 per 100 person-years, incidence of tuberculosis (TB) was 11 per 100 person-years, and incidence of diarrhea was 63 per 100 person-years. Immunosuppression and HIV-1 RNA levels were predictive for pneumonia, oral thrush, and TB but not for diarrhea; CD4 counts <200 cells/mm3 were associated with pneumonia (relative risk [RR] = 2.87, 95% confidence interval [CI]: 1.71 to 4.83), TB (RR = 7.14, 95% CI: 2.93 to 17.40) and thrush. The risk of diarrhea was significantly associated with crowding (RR = 1.86, 95% CI: 1.19 to 2.92) and breast-feeding (RR = 1.71, 95% CI: 1.19 to 2.44). Less than 10% of women reported hospitalization during 2-year follow-up; mortality risk in the cohort was 1.9% and 4.8% for 1 and 2 years, respectively. Conclusions:Mothers with HIV-1, although generally healthy, have substantial morbidity as a result of common infections, some of which are predicted by immune status or by socioeconomic factors. Enhanced attention to maternal health is increasingly important as HIV-1-infected mothers transition from programs targeting the prevention of mother-to-child transmission to HIV care clinics.
Effects of Electrical Muscle Stimulation on Body Composition, Muscle Strength, and Physical Appearance

Electrical muscle stimulation devices (EMS) have been advertised to increase muscle strength, to decrease body weight and body fat, and to improve muscle firmness and tone in healthy individuals. This study sought to test those claims. Twenty-seven college-aged volunteers were assigned to either an EMS (n = 16) or control group (n = 11). The EMS group underwent stimulation 3 times per week following the manufacturer's recommendations, whereas the control group underwent concurrent sham stimulation sessions. Bilaterally, the muscles stimulated included the biceps femoris, quadriceps, biceps, triceps, and abdominals (rectus abdominus and obliques). An identical pre- and posttesting battery included measurements of body weight, body fat (via skinfolds), girths, isometric and isokinetic strength (biceps, triceps, quadriceps, hamstrings), and appearance (via photographs from the front, side, and back). EMS had no significant effect on the any of the measured parameters. Thus, claims relative to the effectiveness of EMS for the apparently healthy individual are not supported by the findings of this study.
Cervical vertebral maturation as a predictor of the adolescent growth spurt

Abstract The aim of this study was to investigate the application of an improved version of the Cervical Vertebral Maturation (CVM) method in a group of indigenous Australians and to relate the ossification events to the timing of peak growth in both stature and the mandible. Data were obtained from longitudinal records of 74 Australian Aboriginal children living at Yuendumu Settlement in the Northern Territory of Australia. CVM stages were limited to particular growth periods: in a large percentage of subjects stage 1 occurred in the pre-peak period of growth, stages 2 and 3 in the peak period, and stages 4 and 5 in the post-peak period. Our findings were similar to those reported in other ethnic groups, suggesting that they can be applied more generally in orthodontic practice to assess a child’s growth activity. In the majority of boys, CVM stage 2 would appear to be a good time to commence an orthopaedic phase of treatment, whereas in girls, results would support an earlier more cautious approach, sometime before stage 2 is reached. Peak growth occurs between stages 2 and 3 and timing is extremely important to maximize the effects of growth in the treatment process.
