    Serial-order short-term memory (STM), as opposed to item STM, has been shown to be very consistently associated with lexical learning abilities in cross-sectional study designs. This study investigated longitudinal predictions between serial-order STM and vocabulary development. Tasks maximizing the temporary retention of either serial-order or item information were administered to kindergarten children aged 4 and 5. At age 4, age 5, and from age 4 to age 5, serial-order STM capacities, but not item STM capacities, were specifically associated with vocabulary development. Moreover, the increase of serial-order STM capacity from age 4 to age 5 predicted the increase of vocabulary knowledge over the same time period. These results support a theoretical position that assumes an important role for serial-order STM capacities in vocabulary acquisition.

    In a sample of 483 serial killers, 6.2% were documented to have committed suicide. Those who committed suicide were found to come from more dysfunctional homes characterized by more psychiatric disturbance in the parents. The sexual acts involved in the murders by the suicides seemed to be more deviant in some aspects, such as committing more bizarre sexual acts or more often taping the murder.

    Recent findings suggest that Hebb repetition learning-a paradigmatic example of long-term serial-order learning-is impaired in adults with dyslexia. The current study further investigated the link between serial-order learning and reading using a longitudinal developmental design. With this aim, verbal and visual Hebb repetition learning performance and reading skills were assessed in 96 Dutch-speaking children who we followed from first through second grade of primary school. We observed a positive association between order learning capacities and reading ability as well as weaker Hebb learning performance in early readers with poor reading skills even at the onset of reading instruction. Hebb learning further predicted individual differences in later (nonword) reading skills. Finally, Hebb learning was shown to explain a significant part of the variance in reading performance above and beyond phonological awareness. These findings highlight the role of serial-order memory in reading ability. Copyright © 2015 Elsevier Inc. All rights reserved.

    Keratinocytes originating from adult human hair follicles, the most convenient biopsy tissue, can be serially cultured using a combination of two techniques. Primary cultures are established using plucked scalp hair follicles and the bovine eye lens capsule as a growth substrate. Subsequently, cells from these cultures are serially cultivated in the presence of irradiated 3T3 cells as feeders. By this combination of techniques many keratinocytes can be generated from one single hair follicle. These cultures, appropriately treated with colchicine, can provide an adequate number of metaphases suitable for chromosome studies.

    Bottom-fermenting Saccharomyces pastorianus strains driving brewing fermentation processes are usually reused several times. It is still unclear, whether the number of successions may have an impact on cell physiology prompting consequences for brewing quality. In this study, fermentation performance of up to twenty consecutive runs in a brewery was investigated. For each run mRNA expression levels of cellular marker molecules, which are known to correlate with metabolism, hexose transport, aging processes, stress response mechanisms and flocculation capability was estimated to obtain information on changes in cell physiology over the successive runs. Low-density microarrays were used for this purpose and the resulting gene expression profiles were finally correlated with changes in the abiotic micro-environments. A surprising stability of the marker molecule expression profiles within each specific serial repitching was stated. Loss of flocculation or an advanced aging could not be detected during serial repitching in the analyzed brewery. However, certain runs of the serial repitchings showed high variation in stress response which was found to be caused by perturbations of the abiotic conditions. Regardless, the study showed that S. pastorianus can be used repeatedly in serial repitching processes without loss of prominent physiological characteristics. Copyright © 2013 Elsevier B.V.

    The hamstring tendon graft has become increasingly popular in anterior cruciate ligament reconstruction because of low donor-site morbidity. However, the tibial fixation is considered difficult, mainly because of low tibial mineral bone density. Therefore, we tested whether preparation of the tibial tunnel with compaction by serial dilation provided a stronger anchorage of the graft-fixation-device complex than does traditional extraction drilling of the tibial tunnel. In 20 bovine tibiae, the bone tunnels were created with either extraction drilling (group 1) or compaction by serial dilation (group 2). Twenty bovine digital extensor tendons were fixated in the bone tunnel with an Intrafix tibial fastener. The graft-fixation-device complexes were mounted in a hydraulic test machine. The fixation strength was evaluated after cyclic loading. The difference between the serial dilation group and the extraction drilling group ranged from a mean slippage of 0 mm at 70-220 N, to a mean slippage of 0.1 mm at 70-520 N. We found no significant difference in slippage of the graft-fixation-device complex after 1,600 cycles. This study failed to show a significant difference between compaction by serial dilation and extraction drilling of the tibia bone tunnel in anterior cruciate ligament reconstruction.

  13. A serial qualitative interview study of infant feeding experiences: idealism meets realism

    2012-01-01

    Objective To investigate the infant feeding experiences of women and their significant others from pregnancy until 6 months after birth to establish what would make a difference. Design Qualitative serial interview study. Setting Two health boards in Scotland. Participants 72 of 541 invited pregnant women volunteered. 220 interviews approximately every 4 weeks with 36 women, 26 partners, eight maternal mothers, one sister and two health professionals took place. Results The overarching theme was a clash between overt or covert infant feeding idealism and the reality experienced. This is manifest as pivotal points where families perceive that the only solution that will restore family well-being is to stop breast feeding or introduce solids. Immediate family well-being is the overriding goal rather than theoretical longer term health benefits. Feeding education is perceived as unrealistic, overly technical and rules based which can undermine women's confidence. Unanimously families would prefer the balance to shift away from antenatal theory towards more help immediately after birth and at 3–4 months when solids are being considered. Family-orientated interactive discussions are valued above breastfeeding-centred checklist style encounters. Conclusions Adopting idealistic global policy goals like exclusive breast feeding until 6 months as individual goals for women is unhelpful. More achievable incremental goals are recommended. Using a proactive family-centred narrative approach to feeding care might enable pivotal points to be anticipated and resolved. More attention to the diverse values, meanings and emotions around infant feeding within families could help to reconcile health ideals with reality. PMID:22422915

    In pharmacokinetic evaluation of mice, using serial sampling methods rather than a terminal blood sampling method could reduce the number of animals needed and lead to more reliable data by excluding individual differences. In addition, using serial sampling methods can be valuable for evaluation of the drug-drug interaction (DDI) potential of drug candidates. In this study, we established an improved method for serially sampling the blood from one mouse by only one incision of the lateral tail vein, and investigated whether our method could be adapted to pharmacokinetic and DDI studies. After intravenous and oral administration of ibuprofen and fexofenadine (BCS class II and III), the plasma concentration and pharmacokinetic parameters were evaluated by our method and a terminal blood sampling method, with the result that both methods gave comparable results (ibuprofen: 63.8 ± 4.0% and 64.4%, fexofenadine: 6.5 ± 0.7% and 7.9%, respectively, in bioavailability). In addition, our method could be adapted to DDI study for cytochrome P450 and organic anion transporting polypeptide inhibition. These results demonstrate that our method can be useful for pharmacokinetic evaluation from the perspective of reliable data acquisition as well as easy handling and low stress to mice and improve the quality of pharmacokinetic and DDI studies. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

  15. Combining confocal laser scanning microscopy with serial section reconstruction in the study of adult neurogenesis.

    Full Text Available Current advances in imaging techniques have extended the possibility of visualizing small structures within large volumes of both fixed and live specimens without sectioning. These techniques have contributed valuable information to study neuronal plasticity in the adult brain. However, technical limits still hamper the use of these approaches to investigate neurogenic regions located far from the ventricular surface such as parenchymal neurogenic niches, or the scattered neuroblasts induced by brain lesions. Here, we present a method to combine confocal laser scanning microscopy (CLSM and serial section reconstruction in order to reconstruct large volumes of brain tissue at cellular resolution. In this method a series of thick sections are imaged with CLSM and the resulting stacks of images are registered and 3D reconstructed. This approach is based on existing freeware software and can be performed on ordinary laboratory personal computers (PC. By using this technique we have investigated the morphology and spatial organization of a group of doublecortin (DCX+ neuroblasts located in the lateral striatum of the late post-natal guinea pig. The 3D study unravelled a complex network of long and poorly ramified cell processes, often fascicled and mostly oriented along the internal capsule fibre bundles. These data support CLSM serial section reconstruction as a reliable alternative to the whole mount approaches to analyze cyto-architectural features of adult germinative niches.

    Serial casting is often prescribed after botulinum toxin injections to improve joint ranges of motion and to potentiate the decrease in hypertonia. The aim of this study was to compare delayed versus immediate serial casting as an adjunct to botulinum toxin therapy for partially reducible spastic equinus. Twelve children who presented spastic equinus associated with mild gastrosoleus contracture took part. Five of them had a diagnosis of spastic diplegia, whereas 7 had a diagnosis of congenital hemiplegia. Children were randomized to immediate serial casting (same day) or delayed serial casting (4 weeks later) after botulinum toxin injection to their gastrosolei. Casts were replaced weekly for 3 weeks. Three children complained of pain that required recasting in the immediate casting group versus none in the delayed casting group (P = 0.08). At 3 months, there was a 27-degree improvement in the fast dorsiflexion angle (Tardieu R1) in the delayed casting group versus 17 degrees in the immediate casting group (P = 0.029). At 6 months, a 19-degree improvement persisted in the delayed group compared with 11 degrees in the immediate group (P = 0.010). There is a clear benefit in delaying serial casting after the injection of botulinum toxin in the recurrence of spasticity at the gastrosoleus that may also offer an advantage regarding the incidence of painful episodes associated with casting. Most importantly, reducing the recurrence of spasticity by delayed serial casting may offer the possibility of decreasing the frequency of botulinum toxin reinjections.

    Serial Palliative Performance Scale (PPS) assessments may predict functional decline and prognosis in cancer and noncancer patients and help with end-of-life decision making. To evaluate the functional status of using serial PPS assessments of patients being assisted in collaboration with the palliative care team (PCT). Prospective cohort pilot study. The sample consisted of 64 cancer and noncancer inpatients being assisted in collaboration with the PCT during the period from 2012 to 2016 (included 12 months). Patients' PPS scores were assessed in three sequential stages: prehospital, first PCT assessment, and outcome (discharge, transference to another unit or death). Functional performance was classified in categories as stable (PPS scores between 70% and 100%), transitional (PPS scores between 40% and 60%), and end of life (PPS scores between 10% and 30%). The mean PPS score during the three assessment stages (respectively, 60.5%, 38.9%, and 25.9%) was significantly different (p PPS scores than noncancer patients; however, both groups exhibited a functional decline along the hospital stay. In both groups there was a negative correlation between the time frame between the different assessment stages and PPS scores (respectively, Pearson -0.4 and -0.6; p PPS assessments are feasible and predicted functional decline in cancer and noncancer patients in this sample. Cancer patients exhibited higher initial functional scores but both cancer and noncancer patients declined in functionality along hospitalization. Earlier deaths occurred in the terminal PPS category than in the transitional PPS category.

  18. A Comparison Study of Stochastic- and Guaranteed- Service Approaches on Safety Stock Optimization for Multi Serial Systems

    Two competing approaches have been developed over the years for multi-echelon inventory system optimization, stochastic-service approach (SSA) and guaranteed-service approach (GSA). Although they solve the same inventory policy optimization problem in their core, they make different assumptions with regard to the role of safety stock. This paper provides a detailed comparison of the two approaches by considering operating flexibility costs in the optimization of (R, Q) policies for a continuous review serial inventory system. The results indicate the GSA model is more efficiency in solving the complicated inventory problem in terms of the computation time, and the cost difference of the two approaches is quite small.

  20. How to standardize vasomotor tone in serial studies based on quantitation of coronary dimensions?

    1998-12-01

    In patients with coronary artery disease including those after coronary bypass graft operation and heart transplantation intervention studies based on serial quantitative coronary angiography, in part combined with intravascular ultrasound, are of increasing relevance. Since vasomotor tone of epicardial coronary arteries is influenced by a variety of factors, angiographic follow-up studies require standardization of coronary tone by induction of maximal dilation. We reviewed the effects of the most potent coronary vasodilatory drug groups, calcium antagonists and nitrocompounds, on coronary diameters. Intravenous or intracoronary injections of verapamil, diltiazem, nifedipine, nicardipine, and nisoldipine can cause profound coronary dilation which has been shown to be maximal with verapamil and nisoldipine. Shortcomings of calcium antagonists include short or unknown duration of action after bolus administration, severe drop in blood pressure, and lack of commercial availability of solutions for injection of many substances. Isosorbide dinitrate induces profound coronary dilation; however, after sublingual administration marked blood pressure decrease can occur, and the duration of action and ideal dose of intracoronary isosorbide dinitrate has not been investigated yet. Injections of molsidomine and its active metabolite, SIN-1, cause longlasting, reproducible, maximal coronary dilation, although only after a waiting period of at least 10 minutes; unfortunately, SIN-1 is only commercially available in France. Nitroglycerin induces reproducible maximal coronary dilation and is easy to administer sublingually or as intracoronary bolus injection with rapid onset of action and no major side effects. The short duration of action may require repeated administrations. To date, repeated intracoronary bolus injections of 0.1 mg nitroglycerin every 10 minutes seem to be the optimal known regimen for standardization of coronary vasomotor tone in serial angiographic studies

    Objective: The primary aim of this prospective study was to use serial 18 F-FDG PET/CT to evaluate the trend of the tumor's maximum standardized uptake value (SUV max ) during radiotherapy (RT) on patients with nasopharyngeal carcinoma (NPC). Methods: 60 patients with primary biopsy-proven NPC were prospectively enrolled into the study, approved by the institutional review board of our hospital. All patients underwent four / 18 F-FDG PET/CT scans: one initial scan before RT/ cisplatin based concurrent chemo radiotherapy, at the point of 50 Gy during RT, the end of RT, and one month after RT, respectively. Results: There was a significant difference (P max of primary site among pre treatment and post treatment at the dose of 50 Gy, at the end of RT and one month after RT. There was also significant difference (P max of neck nodes site. However, there was significant difference of the SUV max between histological WHO type Ⅱ B and type Ⅱ A in the primary site (P=0.044) (67% reduction at dose 50 Gy for type Ⅱ B vs. 55% for type Ⅱ A) but not in the lymph nodes. Conclusions: Serial 18 F-FDG-PET/CT scan demonstrates significant decreasing values of the tumor's SUV max during and after radiotherapy in NPC. The most significant reduction was at the point 50 Gy and SUV is reduced to basal level (≤2.5) at one month after RT both in primary site and lymph nodes. WHO type Ⅱ B has more dramatic response than type Ⅱ A at the primary site but not in lymph node. The study indicates that inflammation caused by RT do not significantly influence the uptake on 18 F-FDG PET in NPC. Therefore, early PET scan during or right after RT instead of conventional 3 months interval after RT is indicated to evaluate tumor response and develop individualized adaptive radiotherapy in NPC.

    Full Text Available Clinical features and results of neuroimagings of an 86 year old woman with the Charles Bonnet syndrome are reported. She had become completely blind bilaterally due to cataracts and glaucoma. Shortly after an operation for cataracts, she developed visual hallucinations which lasted for 22 years. She had no deterioration of intelligence. Computed tomography (CT and magnetic resonance imaging (MRI showed moderate generalized atrophy, particularly of the temporal lobes. A serial single photon emission computed tomography (SPECT study during visual hallucinations demonstrated hyperperfusion in the left temporal region and the basal ganglia and hypoperfusion in the right temporal region. These findings suggest that asymmetrical blood flow, particularly in the temporal regions, may be correlated with visual hallucination in the Charles Bonnet syndrome.

    Radiological monitoring of malignant pleural mesothelioma (MPM) using modified RECIST criteria is limited by low sensitivity and inter-observer variability. Serial serum mesothelin measurement has shown utility in the assessment of treatment response during chemotherapy but has never been assessed in the longer term follow up of patients. This is a single centre study of consecutive patients diagnosed with MPM who received chemotherapy or best supportive care (BSC). Serum mesothelin measurements with paired 6 monthly CT scans were performed following the completion of chemotherapy, or from baseline in the BSC group. Changes in mesothelin were correlated with radiological progression and overall survival. Forty-one patients with MPM were recruited and followed up for a minimum of 12 months (range 12-21 months). The majority of patients (n = 23) received chemotherapy with pemetrexed and cisplatin. Across the cohort a 10% rise in serum mesothelin could predict radiological progression with a sensitivity of 96% (IQR; 79-100) and specificity of 74% (IQR; 50-91). Sensitivity fell to 80% in sarcomatoid only disease. Patients with a rising mesothelin at 6 months had significantly worse overall survival (175 days) compared to stable/falling levels (448 days) (p = 0.003). This is the first study to assess serum mesothelin's ability to detect progression of MPM following chemotherapy or during BSC. A 10% rise in serum mesothelin level showed excellent sensitivity at predicting progressive disease. Mesothelin measurement has several advantages over serial CT imaging including reducing hospital visits and cost.

    We were involved as forensic experts in the case of the serial killer Jeffrey Dahmer. We discuss the scene and victim autopsy findings, with a brief consideration of the basic emotion of hostility. These findings support the thesis that at the basis of this serial killer's behavior were primary unconscious feelings of hate that he had channeled into a sadistic programmed destruction of 17 young men. The interview of the serial killer, the photographic scene documentation, and the autopsy findings stress the ambivalent homosexuality of the killer, his sexual sadism, his obsessive fetishism, and his possible cannibalism and necrophilia.

    Exclusive breastfeeding until six months followed by the introduction of solids and continued breastfeeding is recommended by the World Health Organisation. The dominant approach to achieving this has been to educate and support women to start and continue breastfeeding rather than understanding behaviour change processes from a broader perspective. Serial qualitative interviews examined the influences of significant others on women's feeding behaviour. Thirty-six women and 37 nominated significant others participated in 220 interviews, conducted approximately four weekly from late pregnancy to six months after birth. Responses to summative structured questions at the end of each interview asking about significant influences on feeding decisions were compared and contrasted with formative semi-structured data within and between cases. Analysis focused on pivotal points where behaviour changed from exclusive breastfeeding to introducing formula, stopping breastfeeding or introducing solids. This enabled us to identify processes that decelerate or accelerate behaviour change and understand resolution processes afterwards. The dominant goal motivating behaviour change was family wellbeing, rather than exclusive breastfeeding. Rather than one type of significant other emerging as the key influence, there was a complex interplay between the self-baby dyad, significant others, situations and personal or vicarious feeding history. Following behaviour change women turned to those most likely to confirm or resolve their decisions and maintain their confidence as mothers. Applying ecological models of behaviour would enable health service organisation, practice, policy and research to focus on enhancing family efficacy and wellbeing, improving family-centred communication and increasing opportunities for health professionals to be a constructive influence around pivotal points when feeding behaviour changes. A paradigm shift is recommended away from the dominant approach of

    Rasmussen's syndrome is characterized by intractable seizures and progressive neuropsychiatric deterioration secondary to unilateral cortical inflammation and tissue destruction. Diagnosis of Rasmussen's syndrome in the early phase depends mainly on the clinical features. Neuroimaging and histopathologic examinations may not be specific during this period. We report a case of Rasmussen's syndrome followed by serial MRI and magnetic resonance spectroscopy (MRS) studies over a 3- to 16-month period. A healthy 6-year-old boy presented with focal motor seizures. An MRI study demonstrated prominent enlargement and T2 hyperintensity of the left mesial temporal lobe and perisylvian region. This early finding evolved to volume loss and later progressive atrophy of the ipsilateral hemisphere when epilepsia partialis continua occurred. Being aware of those early MRI features in a patient with increasing frequency of focal motor seizures should suggest Rasmussen's syndrome. In addition, we found prominently increased myoinositol concentration in atrophic cortex which might reflect increased gliosis in the late period of the disease. (orig.)

    1987-01-01

    We have compared the regional distribution of 99Tcm-HMPAO with regional cerebral blood flow (rCBF). CBF was measured by single photon emission computerized tomography (SPECT) using a TOMOMATIC 64 after 133Xe inhalation in 41 patients. With the same SPECT device the distribution of 99Tcm......-HMPAO was measured after i.v. injection. High resolution (HR) and low resolution (LR) studies were performed yielding a resolution of 6 to 10 mm (HR) and 15 to 20 (LR). 99Tcm-HMPAO images showed close resemblance to xenon-133 CBF tomograms. Only about 20% of the (decay corrected) brain counts were lost during...... the first 24 h post injection. A slight decrease in contrast was measured comparing side-to-side asymmetry ratios from the serial studies. This loss of contrast is mainly due to back-diffusion and clearance of a part of the 99Tcm-HMPAO complex from the brain. It could be corrected for by a linearization...

    Reading is an important part of our daily life, and rapid responses to emotional words have received a great deal of research interest. Our study employed rapid serial visual presentation to detect the time course of emotional noun processing using event-related potentials. We performed a dual-task experiment, where subjects were required to judge whether a given number was odd or even, and the category into which each emotional noun fit. In terms of P1, we found that there was no negativity bias for emotional nouns. However, emotional nouns elicited larger amplitudes in the N170 component in the left hemisphere than did neutral nouns. This finding indicated that in later processing stages, emotional words can be discriminated from neutral words. Furthermore, positive, negative, and neutral words were different from each other in the late positive complex, indicating that in the third stage, even different emotions can be discerned. Thus, our results indicate that in a three-stage model the latter two stages are more stable and universal.

    Our goal was to develop a novel technique for inducing Achilles tendinopathy in animal models which more accurately represents the progressive histological and biomechanical characteristic of chronic Achilles tendinopathy in humans. In this animal research study, forty-five rabbits were randomly assigned to three groups and given bilateral Achilles injections. Low dose (LD group) (n = 18) underwent a novel technique with three low-dose (0.1mg) injections of collagenase that were separated by two weeks, the high dose group (HD) (n = 18) underwent traditional single high-dose (0.3mg) injections, and the third group were controls (n = 9). Six rabbits were sacrificed from each experimental group (LD and HD) at 10, 12 and 16 weeks. Control animals were sacrificed after 16 weeks. Histological and biomechanical properties were then compared in all three groups. At 10 weeks, Bonar score and tendon cross sectional area was highest in HD group, with impaired biomechanical properties compared to LD group. At 12 weeks, Bonar score was higher in LD group, with similar biomechanical findings when compared to HD group. After 16 weeks, Bonar score was significantly increased for both LD group (11,8±2,28) and HD group (5,6±2,51), when compared to controls (2±0,76). LD group showed more pronounced histological and biomechanical findings, including cross sectional area of the tendon, Young's modulus, yield stress and ultimate tensile strength. In conclusion, Achilles tendinopathy in animal models that were induced by serial injections of low-dose collagenase showed more pronounced histological and biomechanical findings after 16 weeks than traditional techniques, mimicking better the progressive and chronic characteristic of the tendinopathy in humans.

    To understand successful strategies used by people to cope well when living with advanced cancer; to explore how professionals can support effective coping strategies; to understand how to support development of effective coping strategies for patients and family carers. Qualitative serial (4-12 week intervals) interview study with people with advanced cancer and their informal carers followed by focus groups. The iterative design had a novel focus on positive coping strategies. Interview analysis focused on patients and carers as individuals and pairs, exploring multiple dimensions of their coping experiences. Focus group analysis explored strategies for intervention development. 26 people with advanced (stage 3-4) breast, prostate, lung or colorectal cancer, or in receipt of palliative care, and 24 paired nominated informal/family carers. Participants recruited through outpatient clinics at two tertiary cancer centres in Merseyside and Manchester, UK, between June 2012 and July 2013. 45 patient and 41 carer interviews were conducted plus 4 focus groups (16 participants). People with advanced cancer and their informal/family carers develop coping strategies which enable effective management of psychological wellbeing. People draw from pre-diagnosis coping strategies, but these develop through responding to the experience of living with advanced cancer. Strategies include being realistic, indulgence, support, and learning from others, which enabled participants to regain a sense of wellbeing after emotional challenge. Learning from peers emerged as particularly important in promoting psychological wellbeing through the development of effective 'everyday', non-clinical coping strategies. Our findings challenge current models of providing psychological support for those with advanced cancer which focus on professional intervention. It is important to recognise, enable and support peoples' own resources and coping strategies. Peer support may have potential, and could

    Serial changes of humor comprehension evoked by a well organized four-frame comic Manga were investigated by fMRI in each step of humor comprehension. The neural substrates underlying the amusing effects in response to funny and mixed order manga were compared. In accordance with the time course of the four frames, fMRI activations changed serially. Beginning with the second frame (development scene), activation of the temporo-parietal junction (TPJ) was observed, followed by activations in the temporal and frontal areas during viewing of the third frame (turn scene). For the fourth frame (punch line), strong increased activations were confirmed in the medial prefrontal cortex (MPFC) and cerebellum. Interestingly, distinguishable activation differences in the cerebellum between funny and non-funny conditions were also found for the fourth frame. These findings suggest that humor comprehension evokes activation that initiates in the TPJ and expands to the MPFC and cerebellum at the convergence level.

    The purpose of this study was to investigate and compare the serial changes of morphology and strain in the early process of Achilles tendinopathy in a rabbit model. A total of 10 New Zealand white rabbits underwent ligation of one of their Achilles tendons to induce ischemic injury. Both inflamed and contralateral Achilles tendons were serially evaluated with 3 follow-ups: the first on days 3 to 5, the second on days 9 to 13, and the third and last follow-up on days 15 to 20 after surgery. During each examination, tendon thickness was measured and red, green, and blue pixel intensities of the elastogram were analyzed using color histogram analysis software. Differences between the inflamed and control group were compared. The mean thickness of the inflamed tendons increased during consecutive follow-ups and was significantly larger than that of control tendons (P tendons was also serially increased and was higher than that in the control tendons, indicating softening. However, the difference was significant only in the second and third follow-ups (P Tendon thickening and softening developed during the early process of Achilles tendinopathy in a rabbit model.

    Large vestibular aqueduct syndrome (LVAS) is a congenital disorder characterized by progressive or fluctuating sensorineural hearing loss of unknown etiology. Serial MR examinations were performed before and after the development of hearing loss in two patients with LVAS. The signal and volume of the enlarged endolymphatic sac (EES) vary even in ears with stable hearing. In ears with fluctuating hearing, changes in EES signals were observed in only one of two patients. The finding that the EES volume and signal intensity vary dynamically independently of hearing is important for future research into the pathophysiology of hearing loss in this syndrome. (orig.)

    For more than a century the Halstedian hypothesis of contiguous metastasis from the primary tumor through the lymphatics to distant sites shaped lymph node surgery for melanoma. We challenge this dogma of serial metastatic dissemination. A single-center series of 2,299 patients with cutaneous metastatic melanoma was investigated to analyze overall survival and distant metastasis-free survival of stage IV patients with or without primary lymphatic metastasis. Results were then compared with those of 2,134 patients from three independent centers of the German Central Malignant Melanoma Registry. A multivariate binary logistic regression model was used to identify risk factors for the initial metastatic pathway. Distant metastasis-free survival (hazard ratio = 1.02; 95% confidence interval = 0.91-1.14; P = 0.76) and overall survival (HR = 1.09; 95% CI = 0.96-1.23; P = 0.177) did not differ between stage IV patients with primary hematogenous or primary lymphatic metastasis. Melanoma localization was the only significant risk factor for the initial metastatic pathway. These findings indicate that regional and distant metastases originate from the primary tumor itself in a rather parallel than serial fashion and could explain the lack of survival benefit associated with immediate complete lymph node dissection in sentinel lymph node-positive melanoma patients.

    The widespread use of organophosphate (OP) pesticides has resulted in ubiquitous exposure in humans, primarily through their diet. Exposure to OP pesticides may have adverse health effects, including neurobehavioral deficits in children. The optimal design of new studies requires data on the reliability of urinary measures of exposure. In the present study, urinary concentrations of six dialkyl phosphate (DAP) metabolites, the main urinary metabolites of OP pesticides, were determined in 120 pregnant women participating in the Generation R Study in Rotterdam. Intra-class correlation coefficients (ICCs) across serial urine specimens taken at 25 weeks of pregnancy were determined to assess reliability. Geometric mean total DAP metabolite concentrations were 229 (GSD 2.2), 240 (GSD 2.1), and 224 (GSD 2.2) nmol/g creatinine across the three periods of gestation. Metabolite concentrations from the serial urine specimens in general correlated moderately. The ICCs for the six DAP metabolites ranged from 0.14 to 0.38 (0.30 for total DAPs), indicating weak to moderate reliability. Although the DAP metabolite levels observed in this study are slightly higher and slightly more correlated than in previous studies, the low to moderate reliability indicates a high degree of within-person variability, which presents challenges for designing well-powered epidemiologic studies.

    Weekly serial 4DCT scans were acquired under free breathing conditions to assess water-equivalent path length (WEL) variations due to both intrafractional and interfractional changes in tissue thickness and density and to calculate proton dose distributions resulting from anatomical variations observed in serial 4DCT. A template of region of interests (ROIs) was defined on the anterior-posterior (AP) beam's eye view, and WEL measurements were made over these ROIs to quantify chest wall thickness variations. Interfractional proton dose distributions were calculated to assess changes in the expected dose distributions caused by range variations. Mean intrafractional chest wall WEL changes during respiration varied by: -4.1 mm (<-10.2 mm), -3.6 mm (<-7.1 mm), -3.2 mm (<-5.6 mm) and -2.5 mm (<-5.1 mm) during respiration in the ITV, upper, middle and lower lung regions, respectively. The mean interfractional chest wall WEL variation at Week 6 decreased by -4.0 mm (<-8.6 mm), -9.1 mm (<-17.9 mm), -9.4 mm (<-25.3 mm) and -4.5 mm (<-15.6 mm) in the ITV, upper, middle and lower lung regions, respectively. The variations were decomposed into anterior and posterior chest wall thickness changes. Dose overshoot beyond the target was observed when the initial boli was applied throughout the treatment course. This overshoot is due to chest wall thickness variations and target positional variations. The radiological path length can vary significantly during respiration as well as over the course of several weeks of charged particle therapy. Intrafractional/interfractional chest wall thickness changes can be a significant source of range variation in treatment of lung tumors with charged particle beams, resulting in dose distribution perturbations from the initial plan. Consideration of these range variations should be made in choosing the therapeutic charged particle beam range. (author)

    Full Text Available Objective: To elucidate the progression of angioedema of the head and neck with routine management and to assess the utility of serial physical exams and fiberoptic laryngoscopy in its management. Methods: This study was a prospective observational research. From 2013 to 2014, a prospective observational study was conducted at a tertiary referral center. Forty patient were approached, 7 refused, 33 (18–90 years old were enrolled. Patients presented with angioedema involving the head and neck over a 12 month period were asked to participate in the study. Physical examination and fiberoptic laryngoscopy were performed at presentation and then repeated at least 1 h later. Results: Thirty-three patients with head and neck angioedema from any cause were enrolled (mean age 58, range 23–89 years. The upper lip was the most commonly involved site (58%. On reevaluation, 82% of patients reported subjective improvement in symptoms. The association between subjective improvement and the physical exam, including fiberoptic laryngoscopy findings, was statistically significant (P < 0.001. Conclusion: In stable patients with angioedema of any head and neck subsite, self-reported symptoms are associated with clinical stability or improvement as assessed by physical signs and fiberoptic laryngoscopy. Patients' symptoms may be an appropriate surrogate to monitor clinical status without the need for routine serial physical examinations or fiberoptic laryngoscopy, though further study is needed.

    The current study presents a Bayesian approach to non-compartmental analysis (NCA), which provides the accurate and precise estimate of AUC 0 (∞) and any AUC 0 (∞) -based NCA parameter or derivation. In order to assess the performance of the proposed method, 1,000 simulated datasets were generated in different scenarios. A Bayesian method was used to estimate the tissue and plasma AUC 0 (∞) s and the tissue-to-plasma AUC 0 (∞) ratio. The posterior medians and the coverage of 95% credible intervals for the true parameter values were examined. The method was applied to laboratory data from a mice brain distribution study with serial sacrifice design for illustration. Bayesian NCA approach is accurate and precise in point estimation of the AUC 0 (∞) and the partition coefficient under a serial sacrifice design. It also provides a consistently good variance estimate, even considering the variability of the data and the physiological structure of the pharmacokinetic model. The application in the case study obtained a physiologically reasonable posterior distribution of AUC, with a posterior median close to the value estimated by classic Bailer-type methods. This Bayesian NCA approach for sparse data analysis provides statistical inference on the variability of AUC 0 (∞) -based parameters such as partition coefficient and drug targeting index, so that the comparison of these parameters following destructive sampling becomes statistically feasible.

    Abacus experts have demonstrated extraordinary potential of mental calculation by using an imaginary abacus. But the neural correlates of abacus mental calculation and the imaginary abacus still remain unclear. Here, we report, respectively, the analysis of fMRI images of abacus experts and non-experts in response to the performance of simple and complex serial calculation by visual stimuli as well as the images of the abacus experts with performance of the same tasks by auditory stimuli. We found that activated areas were quite different between two groups. In experts, enhanced activations were mainly observed in fronto-temporal circuit (lateral premotor cortex (LPMC) and posterior temporal areas) in simple addition, but in fronto-parietal circuit (lateral premotor cortex (LPMC) and posterior superior parietal lobe (PSPL)) in complex one. By contrast, in controls, the activated areas were almost similar in both simple and complex tasks, including bilateral inferior parietal lobule, prefrontal and premotor cortices. Furthermore, visual and auditory stimuli generated almost similar activations in experts. These observations reveal that (1) abacus mental calculation induces special patterns of brain response, and simple and complex tasks are sustained by dissociated brain circuits between the temporal and parietal cortices, respectively; (2) the abacus mental calculation may rely on neural resources of visuospatial representations with a super-modal form of abacus beads; (3) the posterior temporal areas and PSPL may be recruited for imaginary abacus.

    2007-05-01

    Event-related brain potentials (ERPs) elicited by recalled and non-recalled words were recorded from 18 female subjects to investigate primacy and recency effects in free memory recall. The typical pattern of a serial position curve (SPC) was obtained with words presented at first and final positions in a list recalled better than words presented in the middle of a list. A marked positivity is seen in the ERPs for words on Primacy, but not on Recency positions at frontocentral electrodes. In contrast, ERP amplitudes on parietal electrodes resemble the SPC seen in behavioral data: P300 amplitude is largest for words on Primacy and Recency positions and attenuated on Plateau positions. Furthermore, subjects with a clear Primacy effect in behavioral data show a distinct frontal positive slow wave for Primacy words only, whereas subjects without a clear primacy effect show a frontal "difference due to subsequent memory" (DM) effect for Primacy and Plateau words. These results are discussed in the framework of working memory and distinctiveness.

    We wanted to demonstrate the temporal changes of the magnetic resonance imaging (MRI) findings in experimentally-induced intramuscular hematomas in rats and to correlate these data with the concurrent pathologic observations. Intramuscular hematoma was induced in 30 rats. The MR images were obtained at 1, 4, 7 and 10 days and at 2, 3, 4, 6 and 8 weeks after muscle injury. The characteristic serial MRI findings were evaluated and the relative signal intensities were calculated. Pathologic specimens were obtained at each time point. On the T1-weighted imaging (T1WI), the intramuscular hematomas exhibited isointensity compared to that of muscle or the development of a high signal intensity (SI) rim on day one after injury. The high SI persisted until eight weeks after injury. On the T2-weighted imaging (T2WI), the hematomas showed high SI or centrally low SI on day one after injury, and mainly high SI after four days. A dark signal rim was apparent after seven days, which was indicative of hemosiderin on the pathology. The gradient echo (GRE) imaging yielded dark signal intensities at all stages. Unlike brain hematomas, experimentally-induced intramuscular hematomas show increased SI on both the T1WI and T2WI from the acute stage onward, and this is pathologically correlated with a rich blood supply and rapid healing response to injury in the muscle. On the T2WI and GRE imaging, high SI with a peripheral dark signal rim is apparent from seven days to the chronic stage

    Background and Purpose: The elastase-induced aneurysm model in rabbits has proved to be suitable for testing new endovascular occlusion devices. The purpose of this study was to evaluate different imaging modalities for the depiction of anatomy and size of elastase-induced aneurysms and for serial follow-up imaging. Materials and Methods: Elastase-induced aneurysms were created in eight Chinchilla bastard rabbits by endoluminal incubation of porcine elastase. Serial imaging was performed using intravenous DSA (IVDSA), contrast-enhanced MRA (CEMRA), and time-of-flight MRA (TOF) 14 days, 4 weeks and 3 months after aneurysm creation. Intraarterial DSA (IADSA) and CT angiography (CTA) were performed after 3 months. Aneurysm size and geometry (height H, width W, neck width N) were compared. Results: On IVDSA after two weeks mean aneurysm height was 6.2 mm (range 2.8-11.0 mm), mean aneurysm neck width was 2.7 mm (range 2.0-4.2 mm) and mean aneurysm neck width was 2.7 mm (range 2.0-4.2 mm). We did not observed any statistically significant change in aneurysm dimensions during follow-up at 4 weeks (CEMRA: H: 5.4, W: 2.4, N: 2.4; TOF: H: 5.7, W: 2.4, N: 2.7) and 3 months (CEMRA: H: 5.8, W: 2.6, N: 2.6; TOF: H: 6.9, W: 2.8, N: 3.0). Aneurysm dimensions could be best seen on IADSA (H: 6.2, W: 3.0, N: 2.7) with good correlation to CTA (r=0.94; H: 6.1, W: 2.8, N: 2.6), CE-MRA (r=0.92), and TOF (r=0.97). TOF was superior to CEMRA in delineating the aneurysm wall. Conclusions: Serial imaging using MRA, CTA or intravenous and intraarterial angiography is feasible in the elastase-induced aneurysm model. Contrast-enhanced MRA, TOF-MRA and CTA showed good correlation to IADSA and are all suitable for non-invasive pretherapeutic measurement of aneurysm size. (orig.) [de

  12. Serial block face-scanning electron microscopy: a tool for studying embryonic development at the cell-matrix interface.

    Studies of gene regulation, signaling pathways, and stem cell biology are contributing greatly to our understanding of early embryonic vertebrate development. However, much less is known about the events during the latter half of embryonic development, when tissues comprising mostly extracellular matrix (ECM) are formed. The matrix extends far beyond the boundaries of individual cells and is refractory to study by conventional biochemical and molecular techniques; thus major gaps exist in our knowledge of the formation and three-dimensional (3D) organization of the dense tissues that form the bulk of adult vertebrates. Serial block face-scanning electron microscopy (SBF-SEM) has the ability to image volumes of tissue containing numerous cells at a resolution sufficient to study the organization of the ECM. Furthermore, whereas light microscopy was once relatively straightforward and electron microscopy was performed in specialist laboratories, the tables are turned; SBF-SEM is relatively straightforward and is becoming routine in high-end resolution studies of embryonic structures in vivo. In this review, we discuss the emergence of SBF-SEM as a tool for studying embryonic vertebrate development. © 2015 Wiley Periodicals, Inc.

    The present study recorded event-related potentials using rapid serial visual presentation paradigm to explore the time course of emotionally charged pictures. Participants completed a dual-target task as quickly and accurately as possible, in which they were asked to judge the gender of the person depicted (task 1) and the valence (positive, neutral, or negative) of the given picture (task 2). The results showed that the amplitudes of the P2 component were larger for emotional pictures than they were for neutral pictures, and this finding represents brain processes that distinguish emotional stimuli from non-emotional stimuli. Furthermore, positive, neutral, and negative pictures elicited late positive potentials with different amplitudes, implying that the differences between emotions are recognized. Additionally, the time course for emotional picture processing was consistent with the latter two stages of a three-stage model derived from studies on emotional facial expression processing and emotional adjective processing. The results of the present study indicate that in the three-stage model of emotion processing, the middle and late stages are more universal and stable, and thus occur at similar time points when using different stimuli (faces, words, or scenes).

    Purpose: To demonstrate that high-dimensional voxel-to-voxel transformations, derived from continuum mechanics models of the underlying pelvic tissues, can be used to register computed tomography (CT) serial examinations into a single anatomic frame of reference for cumulative dose calculations. Methods and Materials: Three patients with locally advanced cervix cancer were treated with CT-compatible intracavitary (ICT) applicators. Each patient underwent five volumetric CT examinations: before initiating treatment, and immediately before and after the first and second ICT insertions, respectively. Each serial examination was rigidly registered to the patient's first ICT examination by aligning the bony anatomy. Detailed nonrigid alignment for organs (or targets) of interest was subsequently achieved by deforming the CT exams as a viscous-fluid, described by the Navier-Stokes equation, until the coincidence with the corresponding targets on CT image was maximized. In cases where ICT insertion induced very large and topologically complex rearrangements of pelvic organs, e.g., extreme uterine canal reorientation following tandem insertion, a viscous-fluid-landmark transformation was used to produce an initial registration. Results: For all three patients, reasonable registrations for organs (or targets) of interest were achieved. Fluid-landmark initialization was required in 4 of the 11 registrations. Relative to the best rigid bony landmark alignment, the viscous-fluid registration resulted in average soft-tissue displacements from 2.8 to 28.1 mm, and improved organ coincidence from the range of 5.2% to 72.2% to the range of 90.6% to 100%. Compared to the viscous-fluid transformation, global registration of bony anatomy mismatched 5% or more of the contoured organ volumes by 15-25 mm. Conclusion: Pelvic soft-tissue structures undergo large deformations and displacements during the external-beam and multiple-ICT course of radiation therapy for locally advanced cervix

  19. The contribution of short-term memory for serial order to early reading acquisition: evidence from a longitudinal study.

    Early reading acquisition skills have been linked to verbal short-term memory (STM) capacity. However, the nature of this relationship remains controversial because verbal STM, like reading acquisition, depends on the complexity of underlying phonological processing skills. This longitudinal study addressed the relation between STM and reading decoding acquisition by distinguishing between STM for item information and STM for order information based on recent studies showing that STM for item information, but not STM for order information, recruits underlying phonological representations. If there is a specific link between STM and reading decoding acquisition, STM for order information should be an independent predictor of reading decoding acquisition. Tasks maximizing STM for serial order or item information, measures of phonological abilities, and reading tests were administered to children followed from kindergarten through first grade. We observed that order STM capacity, but not item STM capacity, predicted independent variance in reading decoding abilities 1 year later. These results highlight the specific role of STM for order in reading decoding acquisition and argue for a causal role of order STM capacity in reading acquisition. Mechanisms relating STM for order information and reading acquisition are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

    In 21 patients who suffered aphasia resulting from left hemisphere ischemic infarction, the xenon 133 inhalation cerebral blood flow technique was used to measure cerebral blood flow within 3 months and 5 to 12 months after stroke. In addition to baseline measurements, cerebral blood flow measurements were also carried out while the patients were performing purposeful listening. In patients with incomplete recovery of comprehension and left posterior temporal-inferior parietal lesions, greater cerebral blood flow occurred with listening in the right inferior frontal region in the late studies than in the early studies. In patients with nearly complete recovery of comprehension and without left posterior temporal-inferior parietal lesions, early listening studies showed diffuse right hemisphere increases in cerebral blood flow. Later listening studies in this latter patient group showed greater cerebral blood flow in the left posterior temporal-inferior parietal region. The study provides evidence for participation of the right hemisphere in language comprehension in recovering aphasics, and for later return of function in left hemisphere regions that may have been functionally impaired early during recovery

    Monitoring in the setting of critical illness must be linked to beneficial therapy to affect clinical outcome. Elevated serum lactate is associated with an increase in mortality in emergency department (ED) patients with severe sepsis and septic shock. The reduction of lactate levels toward normal during acute resuscitation is associated with improved clinical outcomes. The majority of data demonstrating the interventions used to achieve a reduction in lactate levels and the associated clinical outcomes have been obtained during protocolized randomized trials. We therefore conducted a retrospective observational cohort study of 243 adult patients with severe sepsis and septic shock to assess the interventions associated with nonprotocolized serial lactate monitoring and to assess clinical outcomes. A multivariable model was used to assess outcome differences between the serial lactate (SL) and no serial lactate (NL) cohorts. The SL group received more crystalloid resuscitation (3.6 L vs. 2.5 L; P septic shock. This suggests that serial lactate monitoring, targeting a reduction in lactate levels to normal, is a generalizable resuscitation target in the ED.

    Diverticular disease of the colon (DDC), the most common affliction in developed countries, increases in incidence. It is an acquired disease where overactivity of smooth muscle of the colon causes mucosa and sub mucosa to herniate through the muscle layer of the bowel. Starting from 1964, we have periodically carried out radiologic survey to acertain the tendency of DDC to gradually increase in the Koreans. Initially Kim reported the incidence to be 0.2% in 1964 but the incidence in 1979 increased to 2.5% as reported by Chung et al. As the third survey on the series of the study on DDC, we have recently reviewed 1,859 consecutive new cases of double contrast barium enemas performed at the department of radiology, Kangnam St. Mary's Hospital, Catholic University Medical College during the 5 year's period from Feb. 1983 to May 1987. The results were as follows. 1. The present study revealed an incidence 6.0% of DDC, 7.2% in male and 5.0% in female. 2. The distribution of diverticular was 37.0% in cecum, 39.0% in ascending colon, 13.6% in transverse colon, 6.2% in descending colon, 3.7% in sigmoid colon. 3. The mean number of diverticular was 5. 4. The average age of patients with DDC was 50.5 years. From the present study, it has emerged that the diverticular disease of the colon in the Koreans is definitely on gradual increase with a significant change in the site of predominant involvement from the right to the left colon.

    Successful learning of supraspan word lists such as the California Verbal Learning Test (CVLT) relies more on clustering strategies than rote learning, subserved by the frontal and temporal lobes. The authors studied the effect of word sequence in CVLT learning, in 15 patients with frontal (FLL) and 15 temporal (TLL) lesions, and 33 controls. Experimental measures were: number of clusters, number of first (FI), middle (MI) and last items (LI), in learning trials and in total immediate recall. FLL disclosed significantly lower FI along learning. Clusters were similar among groups. This difficulty is discussed according to the role of frontal lobes in learning and memory.

    During the period from June. 1969 to Dec. 1970, the serum protein electrophoretic patterns of 44 cases of various cancer patients have been studied to determine the alterations in serum protein fractions in patients who were responding to irradiation or those failing. The serum electrophoretic pattern could be observed as an indicator of prognosis or radiosensitivity. A blood sample was obtained prior to any treatment and the follow up sampling was performed 2 times during radiation therapy. Serum total protein was determined by the method of Wolfson and serum electrophoresis was carried out by using Spinoco Model R B electrophoresis system. The results were following: Seven cases out of cases of cervical cancer responding favorably to radiotherapy showed decreased in Alpha-2 globulin fraction were increased. A case whose third time serum electrophoretic pattern showed multiple myeloma type died 5 months after radiotherapy with bone metastasis. Four cases out of 9 cases of favorably responded breast cancer patients showed decreased in Alpha-2 globulin foraction compared with 2 cases of unfavorable response showed increased in Alpha-2 globulin fraction

    Purpose: Standardized uptake values (SUV) are standard quantitative PET measures of FDG tumor uptake used,and are used as a tool to monitor response to therapy. Textural analysis is emerging as a new tool for assessing intratumoral heterogeneity which may allow better tissue characterization and improved prediction of response and survival rate.Understanding what variations may be expected in these parameters is key in order to make decisions based on how the change throughout the course of treatment. The aim of this study was to assess repeatability in SUV measures and texture parameters,and establish criteria that differentiate changes associated with treatment rather than statistical variability. Methods: Eighty patients,167 random lesions total,were scanned in a GE Discovery STE PET/CT Scanner. One field-of-view was chosen centered on the largest lesion observed in a clinical whole-body FDG PET.Immediately following,a gated 9 min scan was acquired in list mode,without changing the patient’s position between any scans. Data was replayed into 3 time bins,3 min each,in order to insure equivalent noise characteristics in each replicate.Data was reconstructed into 128×128×47 square matrices.One VOI was drawn over each lesion for each patient and used to segment all 3 replicates. The mean.max and peak SUV were calculated for each VOI and replicate. First-order textural features were also calculated (skewness and kurtosis). Repeatability was calculated as the average standard deviation over the mean for the 3 repeated measurements for each lesion. Results: The average percent error in the SUV max,peak and mean were 3.4%(0– 12.9%),1.9% (0–7.5%),2.8% (0–12.2%),respectively.For skewness and kurtosis they were 10.9% and 17.8%. Conclusion: We have shown that there is a large variation in %error in SUV measures across patients. SUVpeak is the least variable and kurtosis and skewness parameters are less reliable thatn SUVs.Higher order textures are be

    2010-01-01

    Background To use a new medium to dynamically visualize serial optical coherence tomography (OCT) scans in order to illustrate and elucidate the pathogenesis of idiopathic macular hole formation, progression, and surgical closure. Case Presentations Two patients at the onset of symptoms with early stage macular holes and one patient following repair were followed with serial OCTs. Images centered at the fovea and at the same orientation were digitally exported and morphed into an Audiovisual Interleaving (avi) movie format. Morphing videos from serial OCTs allowed the OCTs to be viewed dynamically. The videos supported anterior-posterior vitreofoveal traction as the initial event in macular hole formation. Progression of the macular hole occurred with increased cystic thickening of the fovea without evidence of further vitreofoveal traction. During cyst formation, the macular hole enlarged as the edges of the hole became elevated from the retinal pigment epithelium (RPE) with an increase in subretinal fluid. Surgical repair of a macular hole revealed initial closure of the macular hole with subsequent reabsorption of the sub-retinal fluid and restoration of the foveal contour. Conclusions Morphing videos from serial OCTs are a useful tool and helped illustrate and support anterior-posterior vitreofoveal traction with subsequent retinal hydration as the pathogenesis of idiopathic macular holes.

    Empirical research on serial murder is limited due to the lack of consensus on a definition, the continued use of primarily descriptive statistics, and linkage to popular culture depictions. These limitations also inhibit our understanding of these offenders and affect credibility in the field of research. Therefore, this comprehensive overview of a sample of 508 cases (738 total offenders, including partnered groups of two or more offenders) provides analyses of solo male, solo female, and partnered serial killers to elucidate statistical differences and similarities in offending and adjudication patterns among the three groups. This analysis of serial homicide offenders not only supports previous research on offending patterns present in the serial homicide literature but also reveals that empirically based analyses can enhance our understanding beyond traditional case studies and descriptive statistics. Further research based on these empirical analyses can aid in the development of more accurate classifications and definitions of serial murderers.

    The material budget inside the sensitive tracking volume is highly dependent on the dissipated power for data transmission. It is therefore important to have a very low power serial data link, which allows transmission of digital data over short distances within the tracking volume. This low power ohmic data transmission through micro-twisted transmission lines aims for a transmission speed of 160/320 MHz and allows concentration of the tracker data to multi gigabit optical data hubs.

    Using a commercial software CD and minimal up-mass, SNFM monitors the Payload local area network (LAN) to analyze and troubleshoot LAN data traffic. Validating LAN traffic models may allow for faster and more reliable computer networks to sustain systems and science on future space missions. Research Summary: This experiment studies the function of the computer network onboard the ISS. On-orbit packet statistics are captured and used to validate ground based medium rate data link models and enhance the way that the local area network (LAN) is monitored. This information will allow monitoring and improvement in the data transfer capabilities of on-orbit computer networks. The Serial Network Flow Monitor (SNFM) experiment attempts to characterize the network equivalent of traffic jams on board ISS. The SNFM team is able to specifically target historical problem areas including the SAMS (Space Acceleration Measurement System) communication issues, data transmissions from the ISS to the ground teams, and multiple users on the network at the same time. By looking at how various users interact with each other on the network, conflicts can be identified and work can begin on solutions. SNFM is comprised of a commercial off the shelf software package that monitors packet traffic through the payload Ethernet LANs (local area networks) on board ISS.

    Serial dilution is a fundamental procedure that is common to a large number of laboratory protocols. Automation of serial dilution is thus a valuable component for lab-on-a-chip systems. While a handful of different microfluidic strategies for serial dilution have been reported, approaches based on continuous flow mixing inherently consume larger amounts of sample volume and chip real estate. We employ valve-driven circulatory mixing to address these issues and also introduce a novel device structure to store each stage of the dilution process. The dilution strategy is based on sequentially mixing the rungs of a ladder structure. We demonstrate a 7-stage series of 1 : 1 dilutions with R(2) equal to 0.995 in an active device area of 1 cm(2).

    Both mechanical and multi-element intravascular ultrasound designs have potential advantages and limitations that may impact on their value for clinical and research purposes. Determination of the reproducibility of measurements is critical before a given system can be used in studies such as regression of atherosclerosis trials. We performed serial intravascular ultrasound imaging with catheters using mechanical and phased-array designs in stented and non-stented coronary arteries in dogs and in patients. Both systems correlated well for areas (r > or = 0.90, p or = 0.84. p mechanical designs for measurements of area (mean difference in dogs and in patients: -0.24 and 0.96 mm2, p mechanical system (r > or = 0.96 for all measurements). The differences in absolute and relative variability between the mechanical and phased-array designs, both for reanalysis of same frames and serial pullbacks, were very small. Although multi-element and mechanical intravascular ultrasound designs are not strictly interchangeable, their similar reproducibility and the small differences in measurements demonstrate that both designs are acceptable alternatives for trials of regression of atherosclerosis. Determination of the variability for serial pullbacks of both designs was also important to assess the statistical power of such trials.

    Although speech and vocal music are consistently shown to impair serial recall for visually presented items, instrumental music does not always produce a significant disruption. This study investigated the features of instrumental music that would modulate the disruption in serial recall. 24 students were presented sequences of nine digits and required to recall the digits in order of presentation. Instrumental music as played either forward or backward during the task. Forward music caused significantly more disruption than did silence, whereas the reversed music did not. Some higher-order factor may be at work in the effect of background music on serial recall.

    A low flow rate liquid microjet method for delivery of hydrated protein crystals to X-ray lasers is presented. Linac Coherent Light Source data demonstrates serial femtosecond protein crystallography with micrograms, a reduction of sample consumption by orders of magnitude. An electrospun liquid microjet has been developed that delivers protein microcrystal suspensions at flow rates of 0.14–3.1 µl min −1 to perform serial femtosecond crystallography (SFX) studies with X-ray lasers. Thermolysin microcrystals flowed at 0.17 µl min −1 and diffracted to beyond 4 Å resolution, producing 14 000 indexable diffraction patterns, or four per second, from 140 µg of protein.

    Serial X-ray crystallography allows macromolecular structure determination at both X-ray free electron lasers (XFELs) and, more recently, synchrotron sources. The time resolution for serial synchrotron crystallography experiments has been limited to millisecond timescales with monochromatic beams. The polychromatic, "pink", beam provides a more than two orders of magnitude increased photon flux and hence allows accessing much shorter timescales in diffraction experiments at synchrotron sources. Here we report the structure determination of two different protein samples by merging pink-beam diffraction patterns from many crystals, each collected with a single 100 ps X-ray pulse exposure per crystal using a setup optimized for very low scattering background. In contrast to experiments with monochromatic radiation, data from only 50 crystals were required to obtain complete datasets. The high quality of the diffraction data highlights the potential of this method for studying irreversible reactions at sub-microsecond timescales using high-brightness X-ray facilities.

  7. From animal cruelty to serial murder: applying the graduation hypothesis.

    Although serial murder has been recorded for centuries, limited academic attention has been given to this important topic. Scholars have attempted to examine the causality and motivations behind the rare phenomenon of serial murder. However, scant research exists which delves into the childhood characteristics of serial murderers. Using social learning theory, some of these studies present supporting evidence for a link between childhood animal cruelty and adult aggression toward humans. Based on five case studies of serial murderers, we contribute to the existing literature by exploring the possible link between childhood cruelty toward animals and serial murder with the application of the graduation hypothesis.

    The material budget inside the sensitive tracking volume is highly dependent on the dissipated power for data transmission. It is therefore important to have a very low power serial data link, which allows transmission of digital data over short distances within the tracking volume. This low power ohmic data transmission through micro-twisted transmission lines aims for a transmission speed of 160/320 MHz and allows concentration of the tracker data to multi gigabit optical data hubs. For such a future link we need low swing differential drivers and receivers with PLLs for frequency multipliers and clock recovery. We have implemented in radiation hard layout all the necessary components on a recently submitted 250nm CMOS test chip. After reporting on the experience gained with low power data transmission in the current CMS pixel detector, we present the design considerations and first results for this new 160/320 MHz serial link that may work with differential signal levels as low as 10mV.

    Serial transcriptomics experiments investigate the dynamics of gene expression changes associated with a quantitative variable such as time or dosage. The statistical analysis of these data implies the study of global and gene-specific expression trends, the identification of significant serial changes, the comparison of expression profiles and the assessment of transcriptional changes in terms of cellular processes. We have created the SEA (Serial Expression Analysis) suite to provide a complete web-based resource for the analysis of serial transcriptomics data. SEA offers five different algorithms based on univariate, multivariate and functional profiling strategies framed within a user-friendly interface and a project-oriented architecture to facilitate the analysis of serial gene expression data sets from different perspectives. SEA is available at sea.bioinfo.cipf.es. PMID:20525784

    2011-11-01

    Full Text Available In this paper, we compare three inverse kinematic formulation methods for the serial industrial robot manipulators. All formulation methods are based on screw theory. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. In these three formulation methods, the first one is based on quaternion algebra, the second one is based on dual‐quaternions, and the last one that is called exponential mapping method is based on matrix algebra. Compared with the matrix algebra, quaternion algebra based solutions are more computationally efficient and they need less storage area. The method which is based on dual‐quaternion gives the most compact and computationally efficient solution. Paden‐Kahan sub‐problems are used to derive inverse kinematic solutions. 6‐DOF industrial robot manipulator's forward and inverse kinematic equations are derived using these formulation methods. Simulation and experimental results are given.

    We describe a 15-year-old girl with subacute sclerosing panencephalitis (SSPE) in stage II who was treated with isoprinosine, intraventricular interferon alpha (IFN-α), and ribavirin for 3 years. She is alive at three years from onset and studies at school with the assistance of a special educational teacher. To assess residual brain function, serial (18)FDG-positron emission tomography (PET) was performed three times to measure cortical metabolism: at onset, a year later, and three years later. At onset, PET study revealed preserved glucose metabolism of the cerebral cortex. In serial PET study, glucose metabolism of the cerebral cortex was also preserved even after three years. Although SSPE is a progressive disease of the neuronal system, and typically leads to death in approximately 2-3 years, the neurological prognosis of our case was good. We consider that combination therapy in the very early stage without hypometabolism in the cerebral cortex may be effective for SSPE. Copyright © 2014 European Paediatric Neurology Society.

    2016-01-01

    The question regarding whether somatosensory inputs are processed in parallel or in series has not been clearly answered. Several studies that have applied dynamic causal modeling (DCM) to fMRI data have arrived at seemingly divergent conclusions. However, these divergent results could be explained by the hypothesis that the processing route of somatosensory information changes with time. Specifically, we suggest that somatosensory stimuli are processed in parallel only during the early stage, whereas the processing is later dominated by serial processing. This hypothesis was revisited in the present study based on fMRI analyses of tactile stimuli and the application of DCM to magnetoencephalographic (MEG) data collected during sustained (260 ms) tactile stimulation. Bayesian model comparisons were used to infer the processing stream. We demonstrated that the favored processing stream changes over time. We found that the neural activity elicited in the first 100 ms following somatosensory stimuli is best explained by models that support a parallel processing route, whereas a serial processing route is subsequently favored. These results suggest that the secondary somatosensory area (SII) receives information regarding a new stimulus in parallel with the primary somatosensory area (SI), whereas later processing in the SII is dominated by the preprocessed input from the SI.

    We performed a functional MRI (fMRI) study during the execution of the Paced Visual Serial Addition Task (PVSAT) in 9 patients with a clinically isolated syndrome suggestive of multiple sclerosis (CIS), 9 patients with clinically definite multiple sclerosis (CDMS), and 18 matched healthy control subjects. In controls, the PVSAT elicited a fronto-parietal network with cerebellar activation which we expected for this kind of working memory test and which indicates that this PVSAT version is an appropriate tool for measuring functional changes during a cognitive task. Although there were no significant differences in the actual test results of patients vs. controls, CDMS and CIS patients activated distinct cerebral networks in their attempt to solve the fMRI-PVSAT. Compared to CIS patients, CDMS patients showed increased hippocampal and parahippocampal activation, suggesting the need to additionally support their working memory. In contrast, compared to CDMS patients and healthy controls, CIS patients demonstrated stronger activation of the anterior cingulate cortex, which might indicate focused involvement of executive processes. On the PASAT (Paced Auditory Serial Addition Task) patients also performed similarly to controls but they showed decreased scores on most of the sub-tests of the Wechsler Memory Scale. Based on our observations using the fMRI-PVSAT, we hypothesize that distinct differences in cognitive processing occur with the evolution of MS and that, at these early stages of the disease, they cannot be detected with sufficient sensitivity using only the PASAT.

    As the complex pathogenesis of multiple sclerosis contributes to spatiotemporal variations in the trophic micromilieu of the central nervous system, the optimal intervention period for cell-replacement therapy must be systematically defined. We applied serial, 3D high-resolution magnetic resonance imaging to transplanted neural precursor cells (NPCs) labeled with superparamagnetic iron oxide nanoparticles and 5-bromo-2-deoxyuridine, and compared the migration pattern of NPCs in acute inflamed (n = 10) versus chronic demyelinated (n = 9) brains of mice induced with experimental allergic encephalomyelitis (EAE). Serial in vivo and ex-vivo 3D magnetic resonance imaging revealed that NPCs migrated 2.5 ± 1.3 mm along the corpus callosum in acute EAE. In chronic EAE, cell migration was slightly reduced (2.3 ± 1.3 mm) and only occurred in the lateral side of transplantation. Surprisingly, in 6/10 acute EAE brains, NPCs were found to migrate in a radial pattern along RECA-1+ cortical blood vessels, in a pattern hitherto only reported for migrating glioblastoma cells. This striking radial biodistribution pattern was not detected in either chronic EAE or disease-free control brains. In both acute and chronic EAE brain, Iba1+ microglia/macrophage number was significantly higher in central nervous system regions containing migrating NPCs. The existence of differential NPC migration patterns is an important consideration for implementing future translational studies in multiple sclerosis patients with variable disease. PMID:21305597

  9. Analysis of assembly serial number usage in domestic light-water reactors

    1991-05-01

    Domestic light-water reactor (LWR) fuel assemblies are identified by a serial number that is placed on each assembly. These serial numbers are used as identifiers throughout the life of the fuel. The uniqueness of assembly serial numbers is important in determining their effectiveness as unambiguous identifiers. The purpose of this study is to determine what serial numbering schemes are used, the effectiveness of these schemes, and to quantify how many duplicate serial numbers occur on domestic LWR fuel assemblies. The serial numbering scheme adopted by the American National Standards Institute (ANSI) ensures uniqueness of assembly serial numbers. The latest numbering scheme adopted by General Electric (GE), was also found to be unique. Analysis of 70,971 fuel assembly serial numbers from permanently discharged fuel identified 11,948 serial number duplicates. Three duplicate serial numbers were found when analysis focused on duplication within the individual fuel inventory at each reactor site, but these were traced back to data entry errors and will be corrected by the Energy Information Administration (EIA). There were also three instances where the serial numbers used to identify assemblies used for hot cell studies differed from the serial numbers reported to the EIA. It is recommended that fuel fabricators and utilities adhere to the ANSI serial numbering scheme to ensure serial number uniqueness. In addition, organizations collecting serial number information, should request that all known serial numbers physically attached or associated with each assembly be reported and identified by the corresponding number scheme. 10 refs., 5 tabs

    The objective of this study is to analyze and foresee the international trends related to nuclear activities, especially nuclear non-proliferation activities among others, and to suggest desirable policy direction so as to mitigate hurdles that may hinder the expansion of utilization and development of nuclear energy in Korea. This study approaches the trends of international nuclear arena in five aspects as follows. First, this study analyzes the trends of the global multilateral nuclear non-proliferation regime in Chapter II, which includes the NPT, the IAEA safeguards system, the international export control regime, the CTBT, and the treaties on nuclear weapon-free zone. Second, this study analyzes the trends of various international nuclear organizations in Chapter III, which include IAEA, OECD/NEA, and CTBTO. Third, this study reviews and analyzes regional situations in the northeast Asia surrounding Korea in Chapter IV, inter alia, pending concerns over the North Korean nuclear activities and proposed Northeast Asian nuclear cooperatively bodies such as ASIATOM, etc. Fourth, in Chapter V, this study analyzes issues concerning bilateral nuclear relationship. Especially this study analyzes nuclear cooperating agreements in general, and suggests a model agreement for the government to use when negotiating nuclear cooperation agreements with other countries. Furthermore, this study analyzes the trends of bilateral cooperation with the U.S., Canada, and Australia focusing on the standing bilateral nuclear committees. Fifth, Chapter VI especially deals with the framework of the U. S.'s nuclear non-proliferation policy, focusing on the issues such as the disposition of weapons-usable excess plutonium and the nuclear cooperation with China. (author). 44 refs., 15 tabs., 2 figs

  18. 3D reconstruction by serial sections and gas transport in a porous medium. Application to the study of a clay-loamy soil

    International Nuclear Information System (INIS)

    Cousin, Isabelle

    1996-01-01

    The transport properties of porous media like soil are clearly related to the geometrical characteristics of their porous network. The study of these geometrical properties can be divided in two parts: a morphological study (like form and size of the pores) and a topological part (pore space distribution and connectivity). The properties of gaseous diffusion in a clay-loamy soil have been studied by experiments of marked molecules ( 85 Kr) self-diffusion. The tortuosity measured in this soil core is 2.3 with a free-air porosity of 11.3 %. This soil core was then impregnated with polyester resin and ground as serial sections, 100 micrometers apart. The superimposition of the images made from these sections were characterised by stereo-logical functions (chord distributions functions and correlation functions) and by connected and percolating clusters. We showed that a 2D image, with a porosity close to the 3D reconstruction, exhibits chord distributions similar to the chord distribution of the 3D reconstruction. On the contrary, the distribution of connected clusters calculated on a 2D image and on the 3D reconstruction are different, due to the fact that the determination of connected clusters has no real stereo-logical properties. The determination of the connected clusters within the 3D reconstructed sample showed that 87.6 % of the porous network (studied at this scale) and corresponding to 17.7 % as porosity, is made of a single percolating cluster. The numerical simulation of self-diffusion propagator in the percolating system gives the tortuosity of the reconstructed system. This calculated tortuosity is equal to 1.75 and is close to the experimental tortuosity measured on the real soil sample. This low difference between the calculated and the numerical tortuosity is due to the resolution of the serial sections. This work gives also perspectives for the study of hierarchical porous media at different scales. (author) [fr

  19. Serial Powering of Silicon Sensors

    CERN Document Server

    Villani, E G; Tyndel, M; Apsimon, R

    2007-01-01

    Serial powering is a technique to provide power to a number of serially chained detector modules. It is an alternative option to independent powering that is particularly attractive when the number of modules is high, as in largescale silicon tracking detectors for particle physics. It uses a single power cable and a constant current source. On each module power is derived using local shunt regulators. Design aspects of local shunt regulators and system aspects of serial powering will be discussed. Test results and measurements obtained with a silicon strip supermodule will be presented. Specifications of radiation-hard custom serial powering circuitry will be discussed.

    Serial X-ray crystallography allows macromolecular structure determination at 31 both X-ray Free Electron Lasers (XFELs) and, more recently, synchrotron 32 sources. The time resolution for serial synchrotron crystallography experiments 33 has been limited to millisecond time scales with monochromatic beams. The 34 polychromatic, “pink”, beam provides a more than two orders of magnitude 35 increased photon flux and hence allows accessing much shorter time scales in 36 diffraction experiments at synchrotron sources. Here we report the structure 37 determination of two different protein samples by merging pink beam diffraction 38 patterns from many crystals, each collected with a single 100 ps X-ray pulse 39 exposure per crystal using a setup optimized for very low scattering background. 40 In contrast to experiments with monochromatic radiation, data from only 50 41 crystals were required to obtain complete data sets. The high quality of the 42 diffraction data highlights the potential of this method for studying irreversible 43 reactions at sub-microsecond timescales using high-brightness X-ray facilities. 44

    Full Text Available Malignant catarrhal fever (MCF is a fatal disease especially affecting cattle and buffaloes. A study on the serial blood transmission of MCF was conducted by injecting whole blood of MCF animals into 9 experimental animals. Diagnosis of MCF was based on the clinico-pathological fmdings and polymerase chain reaction (PCR test. The disease has successfully, been achieved in six animals of three Bali cattle and three buffaloes but not in a Bali-cross breed and two Bos indicus (Ongole cattle. Wide range of clinical signs and gross-pathological features were observed. The study showed the degree of susceptibility of experimental animals: Bali cattle and buffalo were highly susceptible (3 out of 3 affected with MCF, Bali-cross breed and Bos indicus (Ongole cattle seemed not susceptible to whole blood experimental transmission. It shows that when Bali cattle acted as inoculum donor, buffalo tended to be clinically more severe than Bali cattle. On the other hand, when buffalo acted as inoculum donor, Bali cattle suffered from MCF more severe than buffalo. The diagnosis of MCF by histopathological examination and the PCR test bad positive correlation (100% in the first experiment, while in the second experiment the PCR test tends to be more sensitive. Based on the restriction endonuclease (RE test, the MCF causal agent in this study appeared to be genetically similar in each case. It is concluded that the serial experimental transmission of MCF by means of whole blood inoculation has been successfully achieved in Bali cattle and buffalo but not in Bali-cross breed and Ongole cattle, and there is a positive correlation between the PCR test and histopathological examination with the PCR test tends to be more sensitive.

    This study was carried out as a part of institutional activities of KAERI. Major research area are as follows; Future directions and effects for national nuclear R and D to be resulted from restructuring of electricity industry are studied. Comparative study was carried out between nuclear energy and other energy sources from the point of views of environmental effects by introducing life cycle assessment(LCA) method. Japanese trends of reestablishment of nuclear policy such as restructuring of nuclear administration system and long-term plan of development and use of nuclear energy are also investigated, and Russian nuclear development program and Germany trends for phase-out of nuclear electricity generation are also investigated. And trends of the demand and supply of energy in eastern asian countries in from the point of view of energy security and tension in the south china sea are analyzed and investigation of policy trends of Vietnam and Egypt for the development and use of nuclear energy for the promotion of nuclear cooperation with these countries are also carried out. Due to the lack of energy resources and high dependence of imported energy, higher priority should be placed on the use of localized energy supply technology such as nuclear power. In this connection, technological development should be strengthened positively in order to improve economy and safety of nuclear energy and proliferation resistance of nuclear fuel cycle and wide ranged use of radiation and radioisotopes and should be reflected in re-establishment of national comprehensive promotion plan of nuclear energy in progress

    Full Text Available This paper belongs to the domestic studies which try to connect the Romanian research to the current debates within the EU studies. The authors' aim is to analyze the aspects and the implications of the EU governance at the Member States' domestic policies level, as most of these policies are currently facing the challenges brought by the Europeanization process. Therefore, the theoretical framework selected is the theory of governance, focusing on the explanatory and analytical opportunities of two components – multi-level governance and governance networks; in this way, it is underlined the separation from the classic model of relation between the (multiplied levels of political authority (supranational, national, subnational and the exponential increase in the number and types of actors participating at the decisional process and implementation of European public policy. Within the selected case studies (environmental policy and education policy, the authors advance a research structure with the aims (a to identify the relevant actors involved in the policy-making process of these policies, at all stages of its cycle; (b to offer an explanation of the types of interactions between these actors, and (c to identify the influence these interactions exert on the communitarization pronounced tendency of some EU policy sectors. The analysis is performed in terms of the Treaty of Lisbon (the selected policies being part of distinct categories of the Union competences and it is oriented towards the national level of the making process of these policies.

  7. Serial position markers in space: visuospatial priming of serial order working memory retrieval.

    Directory of Open Access Journals (Sweden)

    Maya De Belder

    Full Text Available Most general theories on serial order working memory (WM assume the existence of position markers that are bound to the to-be-remembered items to keep track of the serial order. So far, the exact cognitive/neural characteristics of these markers have remained largely underspecified, while direct empirical evidence for their existence is mostly lacking. In the current study we demonstrate that retrieval from verbal serial order WM can be facilitated or hindered by spatial cuing: begin elements of a verbal WM sequence are retrieved faster after cuing the left side of space, while end elements are retrieved faster after cuing the right side of space. In direct complement to our previous work--where we showed the reversed impact of WM retrieval on spatial processing--we argue that the current findings provide us with a crucial piece of evidence suggesting a direct and functional involvement of space in verbal serial order WM. We outline the idea that serial order in verbal WM is coded within a spatial coordinate system with spatial attention being involved when searching through WM, and we discuss how this account can explain several hallmark observations related to serial order WM.

It shows a difference between stiffness behaviours of corresponding industrial robots under external loading, which is caused by machining process. The analysis is based on the estimation of compliance errors induced by cutting forces that are applied to the manipulator end-effector. We demonstrate that the quasi-seral manipulators are preferable for large-dimensional tasks while the quasi-serial ones better suit small size tasks.

    Testicular sperm extraction (TESE) combined with intracytoplasmic sperm injection is becoming a first-line treatment even for non-obstructive azoospermia. The current focus of TESE is the identification of seminiferous tubules that contain spermatozoa and minimization of testicular damage. Although microdissection TESE has been introduced as a preferred procedure for sperm retrieval, no serial follow-up studies of testicular damage have been reported. In the present study, we assayed serum testosterone concentrations and for the presence of antisperm antibodies (ASA) for 1 year after conventional multiple TESE or microdissection TESE and compared postoperative testicular damage between procedures. Thirteen patients who underwent conventional multiple TESE and 12 patients who underwent microdissection TESE were included in this study. Serum total and free testosterone concentrations were evaluated before operation and 1, 6 and 12 months after TESE. Serum ASA was also evaluated before and 12 months after TESE. Serum total and free testosterone concentrations in all patients in both groups showed no significant postoperative decrease. A comparison between the two groups of serum total and free testosterone concentrations showed no significant difference (total testosterone, p = 0.2477; free testosterone, p = 0.3098). No incidence of new ASA formation was identified in the present study. In conclusion, TESE procedures cause neither a decrease of serum testosterone nor formation of ASA. Serum testosterone concentration are similar between patients in the conventional multiple TESE and microdissection groups. Therefore, microdissection TESE is safe with respect to testicular damage, particularly for patients with hypogonadism.

    Survivors of brain tumors in childhood experience adverse sequelae that are greater in prevalence and severity than those encountered by survivors of all other forms of cancer in early life, reflected in a burden of morbidity by instruments measuring health-related quality of life (HRQL). However, there are few studies of the change in HRQL over time in such populations. Patients who were above 5 years of age, at least 2 years from completion of therapy, and able to communicate in English were eligible for study of HRQL by the Health Utilities Index HUI2 and HUI3 at study entry, and again 5 and 10 years later. An initial cohort of 40 patients was reduced to 37 and 25 at the second and third time points, respectively, although only 1 death occurred during the study. HRQL showed a progressive decline over the decade, reaching conventional levels of clinical significance for the sizes of the changes. Median scores for HUI2 were 0.93, 0.90, and 0.88; and for HUI3 were 0.88, 0.85, and 0.77 at baseline, 5, and 10 years, respectively. The serial decline in HRQL demands further examination and an exploration of potential targets for therapeutic intervention.

    Bullying among children is a problem with severe consequences for the victim. The present study examined parent-reported bullying victimization among children in the Nordic countries at two points in time, 1996 and 2011, and studied differences in prevalence of bullying victimization between immigrant and native children. Data came from the parent-reported NordChild, carried out in the Nordic countries in 1996 and 2011. NordChild is a serial cross-sectional comparative study. A total of 7107 children aged 7-13 were included in the analyses. The prevalence of bullying victimization in the total Nordic countries was lower in 2011 (19.2%) than 1996 (21.7%). Difference in prevalence of bullying victimization was found both between native and immigrant children, and between countries. The largest difference in prevalence of bullying victimization was measured in Sweden 2011, where 8.6% of the native children were bullied, to be compared with the 27.8% of the immigrant children. Immigrant children had higher odds to be bullied than native children in Norway, Sweden and in the total Nordic countries at both measurements, also when adjusted for potentially confounding factors. The higher prevalence of bullying victimization among immigrant children should be taken into consideration in the design and development of preventive work against bullying. © 2014 John Wiley & Sons Ltd.

  18. Environmental Pricing: Studies in Policy Choices and Interactions

    DEFF Research Database (Denmark)

    Environmental taxes can be efficient tools for successful environmental policy. Their use, however, has been limited in many countries. This thoughtful book explores the scope of environmental pricing and examines a variety of national experiences in environmental policy integration, to identify...... the most effective use of taxation and policy for environmental sustainability. Environmental taxes are seldom implemented in isolation and are applied in combination with other regulatory instruments. At issue is the critical lack of knowledge on how different policy instruments and taxes interact...... areas of current practice that must be addressed. Empirical studies of policy strategies are discussed to illustrate the extent to which current climate change policy is integrated against the proposed successful policy combinations that are presented in this insightful book.

  19. Dynamics of serial position change in probe-recognition task

    2002-01-01

    Full Text Available Relationship between practice and serial position effects was investigated, in order to obtain more evidence for underlying short-term memory processes. The investigated relationship is termed the dynamics of serial position change. To address this issue, the present study investigated mean latency, errors, and performed Ex-Gaussian convolution analysis. In six-block trials the probe-recognition task was used in the so-called fast experimental procedure. The serial position effect was significant in all six blocks. Both primacy and recency effects were detected, with primacy located in the first two blocks, producing a non-linear serial position effect. Although the serial position function became linear from the third block on, the convolution analysis revealed a non-linear change of the normal distribution parameter, suggesting special status of the last two serial positions. Further, separation of convolution parameters for serial position and practice was observed, suggesting different underlying mechanisms. In order to account for these findings, a strategy shift mechanism is suggested, rather then a mechanism based on changing the manner of memory scanning. Its influence is primarily located at the very beginning of the experimental session. The pattern of results of errors regarding the dynamics of serial position change closely paralleled those on reaction times. Several models of short-term memory were evaluated in order to account for these findings.

    This study aimed to estimate the prevalence of physical activity in different domains and the association with schooling, using a serial cross-sectional population-based design comparing data from two editions of a health survey in the city of São Paulo, Brazil. Participation included 1,667 adults in 2003 and 2,086 in 2008. Probabilistic sampling was performed by two-stage clusters. The long version of International Physical Activity Questionnaire (IPAQ) allowed evaluating multiple domains of physical activity. Poisson regression was used. Men were more active in their leisure time and at work and women in the home. Schooling was associated directly with leisure-time activity (2003 and 2008) and inversely with work-related physical activity (2003) for men and for women in housework. The studies showed that Brazilians with less schooling are becoming less active, so that intervention strategies should consider different educational levels. Interventions in the urban space and transportation can increase the opportunities for physical activity and broaden access by the population.

  1. Serial Input Output

    Energy Technology Data Exchange (ETDEWEB)

    Waite, Anthony; /SLAC

    2011-09-07

    Serial Input/Output (SIO) is designed to be a long term storage format of a sophistication somewhere between simple ASCII files and the techniques provided by inter alia Objectivity and Root. The former tend to be low density, information lossy (floating point numbers lose precision) and inflexible. The latter require abstract descriptions of the data with all that that implies in terms of extra complexity. The basic building blocks of SIO are streams, records and blocks. Streams provide the connections between the program and files. The user can define an arbitrary list of streams as required. A given stream must be opened for either reading or writing. SIO does not support read/write streams. If a stream is closed during the execution of a program, it can be reopened in either read or write mode to the same or a different file. Records represent a coherent grouping of data. Records consist of a collection of blocks (see next paragraph). The user can define a variety of records (headers, events, error logs, etc.) and request that any of them be written to any stream. When SIO reads a file, it first decodes the record name and if that record has been defined and unpacking has been requested for it, SIO proceeds to unpack the blocks. Blocks are user provided objects which do the real work of reading/writing the data. The user is responsible for writing the code for these blocks and for identifying these blocks to SIO at run time. To write a collection of blocks, the user must first connect them to a record. The record can then be written to a stream as described above. Note that the same block can be connected to many different records. When SIO reads a record, it scans through the blocks written and calls the corresponding block object (if it has been defined) to decode it. Undefined blocks are skipped. Each of these categories (streams, records and blocks) have some characteristics in common. Every stream, record and block has a name with the condition that each

    Flotation tests on the lungs and gastrointestinal tract to investigate aeration are classic procedures to examine the life of a newborn after birth; however, there are arguments about the reliability. The present study investigated serial forensic autopsy cases of newborn infants without marked decomposition (n=4) with regard to air/gas distribution in the lungs and gastrointestinal tracts by means of postmortem CT (PM-CT) as well as macromorphology and histology, compared with intrauterine and aborted fetuses (n=3). No gas was detected in the lungs or gastrointestinal tracts in all of three intrauterine fetal deaths. Gas was diffusely detected in the lungs of a newborn fatality attributed to smothering after birth; however, two neonatal fatalities had poor lung gas contents due to marked congestion with edema and diffuse atelectasis. In a case of unsuccessful cardiopulmonary resuscitation following possible birth asphyxia, pulmonary aeration was evidently localized on CT morphology, despite a larger amount of bowel gas, and was also uneven in histology, showing a membranous immunostaining pattern of pulmonary surfactant on the intra-alveolar surfaces of expanded alveoli. The combined use of PM-CT is useful to demonstrate air/gas distributions in the lungs and gastrointestinal tract for interpretation of spontaneous breathing after birth in newborn fatalities.

    To demonstrate the changes in the magnetization transfer ratio (MTR) of different demyelinating plaques, correlating them with the baseline values in T1-weighted contrast-enhanced magnetic resonance (MR) sequences in order to relate them more closely to the underlying disease. The study was based on 33 demyelinating plaques obtained from six patients clinically diagnosed as having remitting-recurring multiple sclerosis (MS). All the patients underwent two MR studies at a 3 to 5-month interval, including contrast-enhanced T1 and T2- weighted sequences and magnetization transfer images. The latter were used to calculate the MTR for each of the demyelinating plaques included in the study. The statistical analysis of the results obtained revealed statistically significant between initial MTR values and those of subsequent T1-weighted sequences. The MTR demonstrate significant differences between plaques according to contrast-enhanced T1-weigh tes sequences, probably indicating variable degrees of edema, demyelination and tissue destruction. These differences should be taken into account to enable the use of T1-weighted sequences to quantify the lesion load in MS patients. (Author) 35 refs

    Although mental illness anxiety is described in the literature, there is very little information on which to draw when treating individuals who present with fears and worries about mental health. In fact, we identified no previous case descriptions focused on this form of anxiety and treated from a cognitive behavioral perspective. The current case study aims to advance the understanding of the clinical picture of mental illness anxiety, and facilitate the understanding of how cognitive behavioral techniques for health anxiety can be effectively adapted and implemented for such a case. A case study approach was adopted in which a baseline condition and repeated assessments were conducted during an 8-week treatment and 2-month follow-up period. In the current case study, we discuss the assessment, conceptualization, and cognitive behavioral treatment of a 24-year old woman who presented with mental illness anxiety. Several common health anxiety assessment tools and cognitive behavioural techniques were adapted for her particular clinical presentation. Consistent with research evidence for health anxiety, significant improvements in health anxiety and anxiety sensitivity were seen after eight sessions of therapy and maintained at 2-month follow-up. The results provide preliminary evidence that cognitive behavioral techniques for health anxiety can be effectively and efficiently adapted for mental illness anxiety. However, the lack of available research pertaining to mental illness anxiety contributes to challenges in conceptualization, assessment and treatment.

    Background Clinical oncological studies attempt to improve precision of data by central radiological assessments. However, it is unclear, to which extent local and central assessments diverge. Purpose To quantify inter-reader variability and the deviation of local from central radiological assessments of computed tomography (CT) scans. Material and Methods This was a sub-study of a randomized clinical phase IIb trial in metastatic renal cell carcinoma (RCC), comparing first-line sorafenib with interferon-alpha-2a (IFN-α-2a). It analyzed agreements of local with central RECIST CT assessments by Cohen's kappa (κ), symmetry tests, deviations in waterfall plots, Bland-Altman plots, and parametric survival analyses. Results The concordance between local and central radiologic review was quantified by κ = 0.53. While local assessment yielded progressive disease (PD) in 18.6%, central assessment classified 22.5% of patient time points as PD exhibiting only a partial overlap with the 18.6% The tumor shrinkage rates in waterfall plots were 68.1% in local and 55.8% in central review (57.8% and 59% by Reader 1 and Reader 2). Bland-Altman plots identified a systematic shift of tumor change rates by -7.5% in local compared to central assessments, that may reflect a systematic tendency of more favorable results in local assessments. The discordance between local and central review was reflected by a time to progression (TTP) hazard ratio (HR) of 1.73 ( P = 0.0003). Conclusion These data suggest that central radiologic review may reduce technical measurement variability in clinical trials, which should be scrutinized in future studies compared to a volumetric reference.

    In vivo 1 H-magnetic resonance imaging (MRI) enabled us to study the distribution of water in living tissues and to document changes in human skeletal muscles during physical exercise. The purpose of the present study was to determine the total muscle water changes after exercise using water in 1 H-MR spectroscopy and to compare these changes to the signal intensity change on T 2 * -weighted images and/or to the T 2 value change. Seven young male volunteers were positioned in a 1.5 T Philips MR imaging system. They were then asked to dorsiflex their ankle joint against a 2 kg weight once every 2 seconds for 2 minutes. The peak height of water declined according to the clearance curve after exercise in all seven cases with the 1 H-MRS similar to the signal intensity. The increasing rate at peak height of total muscle water exceeded both the signal intensity and the T 2 value because the water peak height on the 1 H-MRS included the extracellular water. In addition, we measured the changes in signal intensity in both calf muscles after walking race exercise. The time intensity curves were used to draw a clearance curve for each muscle group after exercise. It was possible to discern which muscle was used most from the T 2 * -weighted image that was obtained once after exercise. (author)

    Adults read at high speed, but estimates of their reading rate vary greatly, i.e., from 100 to 1500 words per minute (wpm). This discrepancy is likely due to different recording methods and to the different perceptual and cognitive processes involved in specific test conditions. The present study investigated the origins of these notable differences in RSVP reading rate (RR). In six experiments we investigated the role of many different perceptual and cognitive variables. The presence of a mask caused a steep decline in reading rate, with an estimated masking cost of about 200 wpm. When the decoding process was isolated, RR approached values of 1200 wpm. When the number of stimuli exceeded the short-term memory span, RR decreased to 800 wpm. The semantic context contributed to reading speed only by a factor of 1.4. Finally, eye movements imposed an upper limit on RR (around 300 wpm). Overall, data indicate a speed limit of 300 wpm, which corresponds to the time needed for eye movement execution, i.e., the most time consuming mechanism. Results reconcile differences in reading rates reported by different laboratories and thus provide suggestions for targeting different components of reading rate.

    The purpose of this document is to present a case study of energy policies in California related to power system transformation and renewable and distributed energy resources (DERs). Distributed energy resources represent a broad range of technologies that can significantly impact how much, and when, electricity is demanded from the grid. Key policies and proceedings related to power system transformation and DERs are grouped into the following categories: 1.Policies that support achieving environmental and climate goals 2.Policies that promote deployment of DERs 3.Policies that support reliability and integration of DERs 4.Policies that promote market animation and support customer choice. Major challenges going forward are forecasting and modeling DERs, regulatory and utility business model issues, reliability, valuation and pricing, and data management and sharing.

    Suicide is a leading cause of death for college students. The aim of this study was to identify risk factors of suicide among college students that could improve university services to help prevent college suicide. We conducted a 23-year serial prevalence study of the prevalence and characteristics of death and suicide among 8,262,314 Japanese college students. We analyzed rates of suicide from the 1989 to 1990 academic year through the 2011-2012 academic year and characterized suicide among this population, focusing on students' sex and psychiatric and academic backgrounds to identify risk factors for suicide. Suicide rates increased throughout the 23 years, and suicide was the leading cause of death every year from 1996 onward. Suicide accounted for 42.4% of all deaths that happened in the 23 years. Male students, medicine majors, students in the final year of their program, and students who completed extra years of schooling or took academic leaves of absence were at higher risk for suicide. Only 16.4% had received an official psychiatric diagnosis and 16.0% had received services through the university health center prior to the suicides. Results suggest the need for a stronger support system for college students. Areas for improvement could include better advertising of mental health services, student and staff education about suicide risk factors, and mentorship and outreach programs for students in their final year of classes, those majoring in medicine, and those who have taken leaves of absence or failed classes. Accommodations at the administrative level would also be helpful for students who need to retake classes or transfer credit. © Copyright 2017 Physicians Postgraduate Press, Inc.

    Teen childbearing is affected by many individual, family, and community factors; however, another potential influence is state policy. Rigorous studies of the relationship between state policy and teen birth rates are few in number but represent a body of knowledge that can inform policy and practice. This article reviews research assessing associations between state-level policies and teen birth rates, focusing on five policy areas: access to family planning, education, sex education, public assistance, and access to abortion services. Overall, several studies have found that measures related to access to and use of family planning services and contraceptives are related to lower state-level teen birth rates. These include adolescent enrollment in clinics, minors' access to contraception, conscience laws, family planning expenditures, and Medicaid waivers. Other studies, although largely cross-sectional analyses, have concluded that policies and practices to expand or improve public education are also associated with lower teen birth rates. These include expenditures on education, teacher-to-student ratios, and graduation requirements. However, the evidence regarding the role of public assistance, abortion access, and sex education policies in reducing teen birth rates is mixed and inconclusive. These conclusions must be viewed as tentative because of the limited number of rigorous studies that examine the relationship between state policy and teen birth rates over time. Many specific policies have only been analyzed by a single study, and few findings are based on recent data. As such, more research is needed to strengthen our understanding of the role of state policies in teen birth rates. Copyright © 2015 Society for Adolescent Health and Medicine.

    Serial murders attract attention from the media, mental health experts, academia, and the general public. We present a case of serial murders that took place in a limited area and which caused public anxiety and anguish in central India. All the victims were homeless beggars, who were bludgeoned to death (crush injury). Individual murders were initially investigated by different police stations; fortunately, since they sent all the bodies to a common autopsy centre, a forensic pathologist was able to link all the cases, the first person to do so. This emphasises the need for sharing information among police stations and autopsy centres.

    Background: Incomplete stent apposition (ISA) is related to stent thrombosis, which is a serious adverse event. We aim to assess the time-course of ISA after 2nd generation everolimus-eluting stent (EES) implantation. Methods: In HEAL-EES study, we enrolled 36 patients who underwent percutaneous coronary intervention (PCI) with EES. OCT imaging was performed at baseline and follow-up. Patients were randomized 1:1:1 into 3 groups according to the time in which follow-up was performed: group A (6-month), group B (9-month), and group C (12-month). In this subanalysis, patients who had ISA segments at baseline and/or follow-up OCT were analyzed. Result: At baseline, among 41 lesions in 36 patients, 20 lesions in 18 patients had ISA segments and were analyzed. At baseline, there were 3.0% ISA struts in group A (n = 8), 2.8% in group B (n = 4), and 4.5% in group C (n = 8). At follow-up, ISA struts were present in 0.09%, 0.16% and 0.64%; respectively in groups A, B, and C. At follow-up, there was a significant decrease in the frequency of ISA: group A 3.0% vs. 0.09% (p < 0.001), group B 2.8% vs. 0.16% (p < 0.001), and group C 4.5% vs. 0.64% (p < 0.001). In group A, there was one late acquired ISA at follow-up. Conclusions: In patients undergoing 2nd generation EES implantation, area of acute ISA assessed by OCT, was almost resolved at 6-month follow-up. - Highlights: • Time-course of incomplete stent apposition of everolimus-eluting stent was assessed. • Serial optical coherence tomography images at baseline and follow-up were evaluated. • Acute incomplete stent apposition was almost resolved as early as at 6 months.

    The aim of this pilot study was to examine the kinetics of alterations in alveolar ridge width and height following tooth extraction with and without ridge preservation, using anorganic bovine bone mineral (ABBM) and a novel device (SocketKAP(™) ) designed for obturation of socket orifice. Maxillary left and right PM1 and mandibular right PM2 and PM4 were extracted on six beagle dogs and treated as follows: Group A: negative control; Group B: SocketKAP(™) alone; Group C: ABBM + SocketKAP(™) . Serial cone-beam computed tomography (CBCT) was taken at 0-, 1-, 2-, 4-, 8- and 12-week intervals to calculate the rate of alveolar bone loss, followed by histologic and histomorphometric analyses at 12 weeks. Across group outcomes were compared. Without additional intervention, the crestal-most 3 mm of alveolar bone width lost approximately 0.21-0.28 mm per week. The rate of alveolar buccal bone height loss was 0.19 mm per week. Comparatively, in group C, the alveolar bone was relatively stable, with loss of only 0.003-0.13 mm of width and 0.12 mm of height per week. These differences were statistically significant. The alveolar bone in sites treated by SocketKAP(™) alone was significantly different from control only at select time points and locations of the ridge, presumably due to small sample size. Without additional intervention, tooth extraction was accompanied by rapid loss of alveolar ridge width and height. Applications of SocketKAP(™) and ABBM were effective in reducing alveolar crestal width and height loss following tooth extraction. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Serial femtosecond crystallography (SFX) at X-ray free-electron lasers (XFELs) is a powerful method to determine high-resolution structures of pharmaceutically relevant membrane proteins. Recently, the technology has been adapted to carry out serial millisecond crystallography (SMX) at synchrotron sources, where beamtime is more abundant. In an injector-based approach, crystals grown in lipidic cubic phase (LCP) or embedded in viscous medium are delivered directly into the unattenuated beam of a microfocus beamline. Pilot experiments show the application of microjet-based SMX for solving the structure of a membrane protein and compatibility of the method with de novo phasing. Planned synchrotron upgrades, faster detectors and software developments will go hand-in-hand with developments at free-electron lasers to provide a powerful methodology for solving structures from microcrystals at room temperature, ligand screening or crystal optimization for time-resolved studies with minimal or no radiation damage.

The article defines the main stages and purposes of evaluation of the competitiveness of the wage policy. The authors studied the use of an estimation of the wage policy competitiveness by the Russian organizations and identified practical need for and methods of assessing the competitiveness of the wage policy. Objective and subjective factors influencing the direction of the wage policy are identified, as well as the trends in wages under the influence of the crisis conditions. The main indicators of mobility and personnel turnover, the average wage in the Irkutsk region are considered. The description of the external conditions of functioning of the organizations in the Irkutsk region is presented.

    Policy work is often cited as one of the primary functions of Hospital Ethics Committees (HECs), along with consultation and education. Hospital policies can have far reaching effects on a wide array of stakeholders including, care providers, patients, families, the culture of the organisation and the community at large. In comparison with the wealth of information available about the emerging practice of ethics consultation, relatively little attention has been paid to the policy work of HECs. In this paper, we hope to advance the development of best practices in HEC policy work by describing the quality improvement process that we undertook at Hamilton Health Sciences, Hamilton, Ontario, Canada. In the first section of the paper we describe the context of our HEC policy work, and the shortcomings of our historical review process. In subsequent sections, we detail the quality improvement project we undertook in 2010, the results of the project and the specific tools we developed to enhance the quality of HEC policy work. Our goal in sharing this organisational case study is to prompt other HECs to publish qualitative descriptions of their policy work, in order to generate a body of knowledge that can inform the development of best practices for ethics policy review.

    In the context of the global obesity epidemic, national nutrition policies have come under scrutiny. The present paper examines whose interests - industry or public health - are served by these policies and why. Using an exemplary case study of submissions to an inquiry into obesity, the research compared the positions of industry and public health groups with that taken by government. We assessed whether the interests were given equal consideration (a pluralist model of influence) or whether the interests of one group were favoured over the other (a neo-pluralist model). 2006 New Zealand Inquiry into Obesity. Food and advertising industry and public health submitters. The Government's position was largely aligned with industry interests in three of four policy domains: the national obesity strategy; food industry policy; and advertising and marketing policies. The exception to this was nutrition policy in schools, where the Government's position was aligned with public health interests. These findings support the neo-pluralist model of interest group influence. The dominance of the food industry in national nutrition policy needs to be addressed. It is in the interests of the public, industry and the state that government regulates the food and advertising industries and limits the involvement of industry in policy making. Failure to do so will be costly for individuals, in terms of poor health and earlier death, costly to governments in terms of the associated health costs, and costly to both the government and industry due to losses in human productivity.

    To evaluate serial ultrasonographic findings of fungal myositis in children. Eleven lesions caused by fungal myositis and occurring in six children were included in this study. Eight lesions in five children were histopathologically proven and the other three were clinically diagnosed. Serial ultrasonographic findings were retrospectively evaluated in terms of size, location, margin, internal echotexture and adjacent cortical change occurring during the follow-up period ranging from five days to two months. Three patients (50%) had multiple lesions. The sites of involvment were the thigh (n=4), calf (n=3), chest wall (n=2), abdominal wall (n=1) and forearm (n=1). Initially, diffuse muscular swelling was revealed, with ill-defined hypoechoic lesions confined to the muscle layer (n=8). Follow-up examination of eight lesions over a period of 5-10 days showed that round central echogenic lesions were surrounded by previous slightly echogenic lesions (n=6, 75%). Long-term follow-up of five lesions over a two-month period revealed periosteal thickening in one case (20%), and the peristence of echogenic solid nodules in four (80%). Pathologic examination showed that the central lesions correlated with a fungus ball and the peripheral slightly echogenic lesions corresponded to hematoma and necrosis. Serial ultrasonographic findings of fungal myositis in children revealed relatively constant features in each case. In particular, the findings of muscular necrosis and a fungus ball over a period of 5-14 days were thought to be characteristic.

    The Alberta Stroke Program Early CT Score (ASPECTS) on baseline imaging is an established predictor of acute ischemic stroke outcomes. We analyzed change on serial ASPECTS at baseline and 24-hour imaging in the Solitaire Flow Restoration with the Intention for Thrombectomy (SWIFT) study to determine prognostic value and to identify subgroups with extensive injury after intervention. ASPECTS at baseline and 24 hours was independently scored in all anterior circulation SWIFT cases, blinded to all other trial data. ASPECTS at baseline, at 24 hours, and serial changes were analyzed with univariate and multivariate approaches. One hundred thirty-nine patients (mean age, 67 [SD, 12] years; 52% women; median National Institutes of Health Stroke Scale, 18 [interquartile range, 8-28]) with complete data at both time points were studied. Multivariate analyses showed that higher 24-hour ASPECTS predicted good clinical outcome (day 90 modified Rankin Scale, 0-2; odds ratio, 1.67; PScale outcomes (mean modified Rankin Scale, 4.4 versus 2.7; P<0.001). Twenty-four-hour ASPECTS provides better prognostic information compared with baseline ASPECTS. Predictors of dramatic infarct progression on ASPECTS are hyperglycemia, hypertension, and nonreperfusion. Serial ASPECTS change from baseline to 24 hours predicts clinical outcome, providing an early surrogate end point for thrombectomy trials. http://www.clinicaltrials.gov.

    Full Text Available Economic development is one of the primary objectives of any government. Fiscal policy represents one of the most effective tools that government authorities could use in order to influence the economy. Having this in mind, this paper focuses on the connection between economic development and fiscal policy and proposes an empirical study based on a sample of 21 European countries. Using a simple pool data model, we tried to distinguish the relations between the evolution of GDP per capita, as a proxy for economic development, and the evolution of three fiscal policy variables, namely the tax burden, the public expenditure to GDP ratio and the budget deficit to GDP ratio.

  13. Reliability, validity, and effectiveness of center of pressure parameters in assessing stabilometric platform in subjects with incomplete spinal cord injury: a serial cross-sectional study

    Science.gov (United States)

    2014-01-01

    Background Spinal cord injury (SCI) can damage long tracts, affecting postural stability. Impairments in balance have recently been proposed to be highly predictive of functional recovery in patients with SCI and thus merit evaluation. In addition to common observational clinical scales, more objective evaluation methods of balance can be implemented by analyzing center of pressure (COP) parameters using stabilometric platforms (SPs). COP analysis has been used in various pathologies, but the COP parameters with regard to measurement vary, depending on the features of the target population, and have only been assessed in healthy subjects. Specifically, concerning subjects with SCI, few studies have reported COP parameters, and none has addressed the reliability, validity, or responsiveness of this measure. The objective of this serial cross-sectional study was to analyze the reliability, validity, and responsiveness of COP parameters under various conditions in incomplete SCI subjects to assess balance. Methods Twenty-three patients with incomplete SCI were examined 111 times for 1 year. Each session comprised administration of the Berg Balance scale, Tinetti scale, and WISCI scale and evaluation of stabilometric platform use. Stabilometry was performed under various sensory conditions (OF: open feet; CF: closed feet; OE: open eyes; CE: closed eyes), wherein several COP parameters were analyzed (L: COP path length; V: mean COP velocity, VAP: anteroposterior COP velocity; VLL: laterolateral COP velocity, A: COP ellipse area, SA1: x-axis of COP ellipse area; SA2: y-axis of COP ellipse area). The reliability, validity, and responsiveness of COP parameters that were associated with visual/support area conditions were analyzed. Results Of the COP parameters, V and arithmetically related measures had the highest reliability, validity, and effectiveness scores. Of all test conditions, OE-OF was the most valid, whereas CE-OF was the most responsive. Conclusion The

    Full Text Available Abstract Background The experiences of people with cancer and organ disease have been described across different dimensions of need as they approach death. Such information is lacking for frail older people approaching death, but could highlight how a palliative approach might be relevant for this population. Methods Cognitively intact, community dwelling adults considered to be moderately or severely frail were recruited from a medical day hospital. Those recruited nominated an informal carer and case-linked professional. Qualitative in-depth serial interviews with older people and their informal carers were conducted over an 18 month period, and single interviews with case-linked healthcare professionals. Interviews were recorded, transcribed and narrative analytical techniques were used to compile case studies. Results Thirty-four participants (13 patients, 13 informal carers and 8 healthcare professionals completed 40 individual, 14 joint and 8 professional interviews. Five patients died during the study. The analysis highlighted a dynamic balance between losses and adaptations. Three typical patterns of multi-dimensional change emerged. 1 Maintenance of psychological and existential well-being with a gradual social decline mirroring the physical deterioration. 2 a gradual reduction in both psychological and existential well-being. 3 a marked downturn in social, psychological and existential well-being before death. Frail older people sustained their well-being through maintaining a sense-of-self, garnering support from carers and community structures, and focusing on living from day to day. Their well-being lessened when they lost their sense-of-self, feeling alienated from the world, and confused over the cause of their circumstances. Death remained distant and ‘undiagnosed’. Social and community frameworks were essential for supporting their well-being. Conclusions Multidimensional end-of-life trajectories for frail older people

    Objectives To assess the value of single and serial fetal biometry for the prediction of small- (SGA) and large-for-gestational-age (LGA) neonates delivered preterm or at term. Methods A cohort study of 3,971 women with singleton pregnancies was conducted from the first trimester until delivery with 3,440 pregnancies (17,334 scans) meeting the following inclusion criteria: 1) delivery of a live neonate after 33 gestational weeks and 2) two or more ultrasound examinations with fetal biometry parameters obtained at ≤36 weeks. Primary outcomes were SGA (95th centile) at birth based on INTERGROWTH-21st gender-specific standards. Fetus-specific estimated fetal weight (EFW) trajectories were calculated by linear mixed-effects models using data up to a fixed gestational age (GA) cutoff (28, 32, or 36 weeks) for fetuses having two or more measurements before the GA cutoff and not already delivered. A screen test positive for single biometry was based on Z-scores of EFW at the last scan before each GA cut-off so that the false positive rate (FPR) was 10%. Similarly, a screen test positive for the longitudinal analysis was based on the projected (extrapolated) EFW at 40 weeks from all available measurements before each cutoff for each fetus. Results Fetal abdominal and head circumference measurements, as well as birth weights in the Detroit population, matched well to the INTERGROWTH-21st standards, yet this was not the case for biparietal diameter (BPD) and femur length (FL) (up to 9% and 10% discrepancy for mean and confidence intervals, respectively), mainly due to differences in the measurement technique. Single biometry based on EFW at the last scan at ≤32 weeks (GA IQR: 27.4–30.9 weeks) had a sensitivity of 50% and 53% (FPR = 10%) to detect preterm and term SGA and LGA neonates, respectively (AUC of 82% both). For the detection of LGA using data up to 32- and 36-week cutoffs, single biometry analysis had higher sensitivity than longitudinal analysis (52% vs 46

    The aim of the present study was to compare lesion morphologies after sirolimus-eluting stent (SES) implantation between patients with unstable angina pectoris (UAP) and stable angina pectoris (SAP) with the use of optical coherence tomography (OCT). The lesion morphologies before and after coronary stenting have been proposed as important predictors of clinical outcome. The high resolution of OCT provides detailed information of coronary vessel wall. We enrolled 55 patients (UAP: n = 24, SAP: n = 31), and examined lesion morphologies by using OCT at pre- and post-SES implantation and 9 months' follow-up. The incidence of plaque rupture (42% vs. 3%, p < 0.001), intracoronary thrombus (67% vs. 3%, p < or = 0.001) and thin-capped fibroatheroma (cap thickness <65 microm; 46% vs. 3%, p < 0.001) at pre-intervention was significantly greater in UAP than that in SAP. Although stent profiles and procedural characteristics were not different between the 2 groups, inadequate stent apposition (67% vs. 32%, p = 0.038) and tissue protrusion (79% vs. 42%, p = 0.005) after percutaneous coronary intervention were observed more frequently in patients with UAP. Plaque rupture was significantly increased after percutaneous coronary intervention in patients with UAP (42% to 75%, p = 0.018), and the persistence of core cavity after plaque rupture (28% vs. 4%, p = 0.031) at 9 months' follow-up was observed more frequently in UAP patients compared with SAP patients. At 9 months' follow-up, the incidence of inadequately apposed stent (33% vs. 4%, p = 0.012) and partially uncovered stent by neointima (72% vs. 37%, p = 0.019) was significantly greater in UAP patients than that in SAP patients. All patients took aspirin and ticlopidine during follow-up period, and no patients had stent thrombosis or adverse coronary events. Serial OCT examinations demonstrated markedly different vascular response up to 9 months after SES implantation between UAP and SAP patients. Although the inadequate

    Following Cambodia's implementation of the 100% condom use program with enforcement of condom use and STI treatment services for sex workers in 2001, sexually transmitted infection and HIV declined markedly. In 2008, Cambodia implemented a law to ban brothel-based sex work. We reported trends in unprotected vaginal intercourse with sex workers among heterosexual men buying sex before (2003-2008) and after (2009-2012) the brothel ban in Cambodia. We also determined the association of brothel ban with these men's reports of unprotected intercourse with sex workers. In this serial cross-sectional study, we collected yearly behavioural data on random cross-sectional samples of heterosexual men buying sex who attended the only government health centre in Siem Reap for voluntary confidential counselling and testing (VCCT) between 2003 and 2012. We used multivariable Poisson regression analysis on the 10-year data of 976 men to obtain the adjusted prevalence ratio (aPR) of unprotected intercourse in the last 6 months by brothel closure. Men buying sex from non-brothel-based sex workers increased almost 3-fold from 17% in 2007-2008 before brothel closure to 55% in 2011-2012 after brothel closure (p < 0.001). Unprotected intercourse with sex workers in the last week increased significantly from 37% (2003-2004) before brothel closure to 65% (2011-2012) after brothel closure. This increase corresponded closely with the increase in self-reported unprotected intercourse from 35% to 61% by the sex workers (n = 1805) attending the same clinic for VCCT. Brothel closure was associated with an increased risk (aPR: 1.65; 95% CI: 1.40-1.94) of unprotected intercourse with sex workers. HIV prevalence in the heterosexual men declined significantly from 26% in 2003-2004 to 4.8% in 2007-2008 and 0 case in 2009-2010 before increasing to 5.6% in 2011-2012. Our findings suggest that the brothel ban had led to an increase in unprotected intercourse with all sex workers for men buying

Yet film studies scholarship has shown how attending to the integration of performances with other aspects of film style is crucial to the interpretation and appreciation of expression and meaning in filmed narrative fictions. However, as a particle form of filmed serial narrative, series television raises a number of questions about performance that will not necessarily be satisfyingly addressed by the direct adoption and application of approaches to writing about performance that have been honed in regard to film. How, then, do we write about performance in television serials in ways that recognise and accommodate the form’s relationship to film, while at the same time appropriately acknowledging and responding to long-form television’s serial status? To examine the difficulties and opportunities of approaching performance in serial television this way, the article conducts close readings of various pieces of television studies writing on performance, by scholars such as Jason Mittell, Sue Turnbull, George Toles, and Steven Peacock. Their work brings into view film and television’s points of common relation, and the distinctive challenges, achievements, and rewards of appreciating the best television serials, and the performances in them.

  2. The fallacy of serial extractions.

    Lee, K Paul

    2013-11-01

    It is suggested that lingually-positioned lower lateral incisors in young children are anatomically correct and not a symptom of crowding. Primary canines with intact periodontal attachments have an important role to play as proprioceptors to encourage growth of the alveolar arch. Extractions of primary cuspids would deprive the alveolus of important growth stimuli. Clinical evidence suggests that serial extraction is counter-productive. The early extraction of primary cuspids will invariably result in crowding of the permanent cuspids. It is a common belief that serial extraction corrects the crowding of lower incisors but the procedure is not evidence based. In reality, the problem is maintained and the 'crowding' shifts to involve the permanent cuspids. Let us not forget the most basic canon of the health profession which is 'first do no harm, and if it is not broken, do not try to fix it'.

    A ten megabit per second serial data repeater system has been developed for the 6.28km Tevatron accelerator. The repeaters are positioned at each of the thirty service buildings and accommodate control and abort system communications as well as distribution of the Tevatron time and energy clocks. The repeaters are transparent to the particular protocol of the transmissions. Serial data are encoded locally as unipolar two volt signals employing the self-clocking Manchester Bi-Phase code. The repeaters modulate the local signals to low-power bursts of 50 MHz rf carrier for the 260m transmission between service buildings. The repeaters also demodulate the transmission and restructure the data for local utilization. The employment of frequency discrimination techniques yields high immunity to the characteristic noise spectrum

    Full Text Available Jane Austen sells. She sells in all possible ways, her novels have been adapted for the cinema and the stage, they have been rewritten as comics and graphic novels. Jane austen is a cultural icon. The interest in her life is so strong that many biographies have been written in order to recover new facts and details. The places where she has lived and the places depicted in her novels have become tourist sites for literary pilgrims. Austen is a cross-over phenomenon, with regency costume balls recreated in her name and an endless proliferation of her works in all media. My essay will investigate Jane Austen and Seth Grahame-Smith’s Pride and Prejudice and Zombies (2009, a mash-up novel which has become a real cultural phenomenon of the last decade and will demonstrate how it can be considered a serial narrative. If as Henry Jenkins asserts, seriality implies the unfolding of a story over time through a process of “chunking” (that is creating meaningful parts of the same story and of “dispersal” (that is breaking the story into more parts and in more genres and media, mash-ups seems to do this.  Austen’s story remains as a “story hook” which pushes the reader to come back to different products for a continuation of the same story. So, if on the one hand, seriality occurs within the same text, the story-telling of Austen’s stories across genres and media is part of a seriality process.

    2012-02-01

    This Special Issue of Social Science & Medicine investigates the potential for positive inter-disciplinary interaction, a 'generative dance', between organization studies (OS), and two of the journal's traditional disciplinary foundations: health policy and medical sociology. This is both necessary and timely because of the extent to which organizations have become a neglected topic within medical sociology and health policy analysis. We argue there is need for further and more sustained theoretical and conceptual synergy between OS, medical sociology and health policy, which provides, on the one-hand a cutting-edge and thought-provoking basis for the analysis of contemporary health reforms, and on the other hand, enables the development and elaboration of theory. We emphasize that sociologists and policy analysts in healthcare have been leading contributors to our understanding of organizations in modern society, that OS enhances our understanding of medical settings, and that organizations remain one of the most influential actors of our time. As a starting point to discussion, we outline the genealogy of OS and its application to healthcare settings. We then consider how medical sociology and health policy converge or diverge with the concerns of OS in the study of healthcare settings. Following this, we focus upon the material environment, specifically the position of business schools, which frames the generative dance between OS, medical sociology and health policy. This sets the context for introducing the thirteen articles that constitute the Special Issue of Social Science & Medicine. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available The reconstruction of a death scene provides an overall picture of the crime and will indicate the murder as an event or one of a series of events and also the criminal. But when the criminal is declared a serial killer, many questions are raised up. How could a person kill some else without a reason or why people react in such a disorganized way and become so brutal or what made them act like that and so many questions with also so many answers. This project explains the psychology of a murderer, his own way of thinking and acting by presuming that we may accurately discover what is in their minds when they kill. It is about a very complex issue regarding murder investigations, biological factors and psychological profile of a serial killer. Dealing with this problem we will at last reach to the question that could solve finally the puzzle: ―Are serial murderers distorted reflections of society's own values?

    Nuclear safety policy in Korea is currently declared in the Nuclear Safety Charter as the highest tier document and safety principles and directions are announced in the Nuclear Safety Policy Statement. As the circumstances affecting on the nuclear safety policy change, it needs to revise the Statement. This study aims to develop the revised Nuclear Safety Policy Statement to declare that securing safety is a prerequisite to the utilization of nuclear energy, and that all workers in nuclear industry and regulatory body must adhere to the principle of priority to safety. As a result, two different types of revision are being prepared as of August. One is based on the spirit of Nuclear Safety Charter as well as the direction of future-oriented safety policies including the changes in the environment after declaration of the Statement. The other is to declare the fundamental safety objective and safety principles as the top philosophy of national nuclear safety policy by adopting the '10 Safety Principles in IAEA Safety Fundamental' instead of the current Charter. Both versions of revision are subject to further in-depth discussion. However once the revision is finalized and declared, it would be useful to accomplish effectively the organizational responsibilities and to enhance the public confidence in nuclear safety by performing the regulatory activities in a planned and systematic manner and promulgating the government's dedication to priority to safety

    It is of the utmost importance in the peaceful use and development of nuclear energy to respond in a timely manner to the changes of international nuclear communities. This study were carried focused on the trends of international movements related to nuclear non-proliferation regime and major trends in the international bi- or multi-lateral technical cooperation activities. This study investigates the major changes of international technical cooperation focusing on nuclear functional organizations, IAEA and OECD/NEA which become competent and important in the international technical cooperation. 9.11 terror and international illegal trafficking of A. Q. Khan network caused the strengthening of international nonproliferation regimes and international efforts and measures against threat of nuclear terror and this movement will kept in the international communities afterwards with GTRI, G8 action plan, UN resolution of WMD and ratification and application of additional protocol of IAEA safeguards agreement into member countries. Upgrade of nuclear diplomatic and technical networks and activities are required to secure the national rights and dignity in the international communities in effective and systematic manners through the enlarged participation and contribution of the national experts to working groups activities of IAEA and OECD/NEA together.

    Policy on environmental tobacco smoke and its effect on indoor air quality are discussed in this paper. Passive (secondhand) smoke is examined in aspects ranging from health effects to laws surrounding smoking within public buildings in the United States. Engineering and administrative solutions to these indoor air quality problems are considered. A case study of a smoking area within an institutional building is presented and potential improvements and administrative actions are discussed. The results of this study should be helpful to those faced with or anticipating technical and legal indoor air quality problems and policy decisions. (orig.)

  18. Serial position learning in honeybees.

    Directory of Open Access Journals (Sweden)

    Randolf Menzel

    Full Text Available Learning of stimulus sequences is considered as a characteristic feature of episodic memory since it contains not only a particular item but also the experience of preceding and following events. In sensorimotor tasks resembling navigational performance, the serial order of objects is intimately connected with spatial order. Mammals and birds develop episodic(-like memory in serial spatio-temporal tasks, and the honeybee learns spatio-temporal order when navigating between the nest and a food source. Here I examine the structure of the bees' memory for a combined spatio-temporal task. I ask whether discrimination and generalization are based solely on simple forms of stimulus-reward learning or whether they require sequential configurations. Animals were trained to fly either left or right in a continuous T-maze. The correct choice was signaled by the sequence of colors (blue, yellow at four positions in the access arm. If only one of the possible 4 signals is shown (either blue or yellow, the rank order of position salience is 1, 2 and 3 (numbered from T-junction. No learning is found if the signal appears at position 4. If two signals are shown, differences at positions 1 and 2 are learned best, those at position 3 at a low level, and those at position 4 not at all. If three or more signals are shown these results are corroborated. This salience rank order again appeared in transfer tests, but additional configural phenomena emerged. Most of the results can be explained with a simple model based on the assumption that the four positions are equipped with different salience scores and that these add up independently. However, deviations from the model are interpreted by assuming stimulus configuration of sequential patterns. It is concluded that, under the conditions chosen, bees rely most strongly on memories developed during simple forms of associative reward learning, but memories of configural serial patterns contribute, too.

    The GEO-2000 study into alternative policy options for Europe and Central Asia focuses on energy use as an important driver for environmental problems across the region. The problems analyzed are climate change, acidification, summer smog, urban air pollution and risks of reactor accidents associated with nuclear power generation. The analysis includes the effects on biodiversity and population health. It considers the question of what can be achieved by moderate measures, and whether this will be enough. Similar Geo-2000 region-specific studies on alternative policies have been compiled other world regions. This report outliners the general methodology for these reports

  5. Serial recall of colors: Two models of memory for serial order applied to continuous visual stimuli.

    Peteranderl, Sonja; Oberauer, Klaus

    2018-01-01

    This study investigated the effects of serial position and temporal distinctiveness on serial recall of simple visual stimuli. Participants observed lists of five colors presented at varying, unpredictably ordered interitem intervals, and their task was to reproduce the colors in their order of presentation by selecting colors on a continuous-response scale. To control for the possibility of verbal labeling, articulatory suppression was required in one of two experimental sessions. The predictions were derived through simulation from two computational models of serial recall: SIMPLE represents the class of temporal-distinctiveness models, whereas SOB-CS represents event-based models. According to temporal-distinctiveness models, items that are temporally isolated within a list are recalled more accurately than items that are temporally crowded. In contrast, event-based models assume that the time intervals between items do not affect recall performance per se, although free time following an item can improve memory for that item because of extended time for the encoding. The experimental and the simulated data were fit to an interference measurement model to measure the tendency to confuse items with other items nearby on the list-the locality constraint-in people as well as in the models. The continuous-reproduction performance showed a pronounced primacy effect with no recency, as well as some evidence for transpositions obeying the locality constraint. Though not entirely conclusive, this evidence favors event-based models over a role for temporal distinctiveness. There was also a strong detrimental effect of articulatory suppression, suggesting that verbal codes can be used to support serial-order memory of simple visual stimuli.

  6. The Relationship Context of Premarital Serial Cohabitation.

    2010-09-01

    Even though serial cohabitation is on the rise, it has not been integrated into recent family research. We analyze the National Survey of Family Growth (NSFG) cycle 6 to explore the relationship context of serial cohabitation for women throughout emerging adulthood (N=3,397). We provide a relationship context for serial cohabitation by examining the age at first cohabitation, duration of cohabiting unions, marital expectations and transitions, as well as premarital sexual histories. Furthermore, we examine the change in these relationship indicators across women's birth cohorts. We find that serial cohabitors' co-residential unions are about the same duration as single-instance cohabiting unions. Serial cohabitors start cohabiting younger, report lower marital expectations than single-instance cohabitors and a smaller proportion marry before age 30. Women who have more premarital sex partners have significantly greater odds of serial cohabiting. These findings indicate that women face increasingly complex relationship trajectories during emerging adulthood.

  7. Serial dependencies act directly on perception.

    Cicchini, Guido Marco; Mikellidou, Kyriaki; Burr, David

    2017-12-01

    There is good evidence that biological perceptual systems exploit the temporal continuity in the world: When asked to reproduce or rate sequentially presented stimuli (varying in almost any dimension), subjects typically err toward the previous stimulus, exhibiting so-called "serial dependence." At this stage it is unclear whether the serial dependence results from averaging within the perceptual system, or at later stages. Here we demonstrate that strong serial dependencies occur within both perceptual and decision processes, with very little contribution from the response. Using a technique to isolate pure perceptual effects (Fritsche, Mostert, & de Lange, 2017), we show strong serial dependence in orientation judgements, over the range of orientations where theoretical considerations predict the effects to be maximal. In a second experiment we dissociate responses from stimuli to show that serial dependence occurs only between stimuli, not responses. The results show that serial dependence is important for perception, exploiting temporal redundancies to enhance perceptual efficiency.

  9. Short- and long-term memory contributions to immediate serial recognition: evidence from serial position effects.

    Purser, Harry; Jarrold, Christopher

    2010-04-01

    A long-standing body of research supports the existence of separable short- and long-term memory systems, relying on phonological and semantic codes, respectively. The aim of the current study was to measure the contribution of long-term knowledge to short-term memory performance by looking for evidence of phonologically and semantically coded storage within a short-term recognition task, among developmental samples. Each experimental trial presented 4-item lists. In Experiment 1 typically developing children aged 5 to 6 years old showed evidence of phonologically coded storage across all 4 serial positions, but evidence of semantically coded storage at Serial Positions 1 and 2. In a further experiment, a group of individuals with Down syndrome was investigated as a test case that might be expected to use semantic coding to support short-term storage, but these participants showed no evidence of semantically coded storage and evidenced phonologically coded storage only at Serial Position 4, suggesting that individuals with Down syndrome have a verbal short-term memory capacity of 1 item. Our results suggest that previous evidence of semantic effects on "short-term memory performance" does not reflect semantic coding in short-term memory itself, and provide an experimental method for researchers wishing to take a relatively pure measure of verbal short-term memory capacity, in cases where rehearsal is unlikely.

  10. Malingering, coaching, and the serial position effect.

    2002-01-01

    The normal pattern of performance on list-learning tasks is to recall more words from the beginning (primacy) and end (recency) of the list. This pattern is also seen in patients with closed head injury, but malingerers tend to recall less words from the beginning of word lists, leading to a suppressed primacy effect. The present study examined this pattern on both learning trials and delayed recall of the Auditory Verbal Learning Test (AVLT) in 34 persons performing with normal effort, 38 naive malingerers, 33 warned malingerers, and 29 head-injured patients. Both malingering groups had lower scores on the primacy portion of the list during learning trials, while normals and head-injured patients had normal serial position curves. During delayed recall, normals and head-injured patients did better than the two malingering groups on middle and recency portions of the list. Findings suggest that the serial position effect during learning trials may be a useful pattern of performance to watch for when suspicious of malingering.

  11. Serial Cognition and Personality in Macaques

    Full Text Available We examined the associations between serial cognition and personality in rhesus macaques (Macaca mulatta. Nine macaques were tested on a simultaneous chaining task to assess their cognitive abilities. They were also rated for personality traits and scored according to a previously extracted six component structure derived from free-ranging rhesus macaques. Friendliness and Openness were positively associated with good performance on three measures of accuracy on the serial learning task: Progress, Error, and Rewarded (i.e., correctly completed Trials. Faster Reaction Times were associated with lower Friendliness and higher Confidence, as well as higher Openness when only correct responses were analyzed. We also used regularized exploratory factor analysis to extract two, three, four, five, and six factor structures, and found consistent associations between accuracy and single factors within each of these structures. Prior results on intelligence in other nonhuman primate species have focused on basic intelligence tests; this study demonstrates that more complex, abstract cognitive tasks can be used to assess intelligence and personality in nonhuman primates.

  17. On the Science-Policy Bridge: Do Spatial Heat Vulnerability Assessment Studies Influence Policy?

    Directory of Open Access Journals (Sweden)

    Tanja Wolf

    2015-10-01

    Full Text Available Human vulnerability to heat varies at a range of spatial scales, especially within cities where there can be noticeable intra-urban differences in heat risk factors. Mapping and visualizing intra-urban heat vulnerability offers opportunities for presenting information to support decision-making. For example the visualization of the spatial variation of heat vulnerability has the potential to enable local governments to identify hot spots of vulnerability and allocate resources and increase assistance to people in areas of greatest need. Recently there has been a proliferation of heat vulnerability mapping studies, all of which, to varying degrees, justify the process of vulnerability mapping in a policy context. However, to date, there has not been a systematic review of the extent to which the results of vulnerability mapping studies have been applied in decision-making. Accordingly we undertook a comprehensive review of 37 recently published papers that use geospatial techniques for assessing human vulnerability to heat. In addition, we conducted an anonymous survey of the lead authors of the 37 papers in order to establish the level of interaction between the researchers as science information producers and local authorities as information users. Both paper review and author survey results show that heat vulnerability mapping has been used in an attempt to communicate policy recommendations, raise awareness and induce institutional networking and learning, but has not as yet had a substantive influence on policymaking or preventive action.

    Full Text Available Policy accountability is a form of manifestation of public officials responsible to the people. One form of policy accountability that is discussed here is street vendors policy accountability, because they are a group of citizens who have the economic activities in public spaces. The existence of this policy how-ever, the number of street vendors from year to year increase in Makassar City. Therefore, this study seeks to uncover and explain the democratic policy ac-countability through the street vendors’ responses and expectations to the implementation of street ven-dors empowerment policy in Makassar City; and to uncover and explain the democratic policy account-ability through the stakeholders’ responses and ex-pectations to the implementation of street vendors empowerment policy in Makassar City. To achieve these objectives, the study uses democracy theory, in which this theory focuses on togetherness in dis-cussing solutions to the various problems of street vendors and in the policy implementation as well.This study used a qualitative design and case studies strat-egy. Data collection techniques used was observa-tion, interview, and documentation. Data were ana-lyzed with case description its settings. The results of this study pointed out that the interests and needs of the street vendors are not met through the empow-erment policies vendors. This is caused by the ab-sence of accountability forum as a place of togeth-erness all of street vendors empowerment stakehold-ers’. Street vendors empowerment policy in Makassar City are designed base on a top-down approach, so they are considered as objects, which must accept all government programs aimed at them.

    2012-06-04

    A large, district-wide, home-based HIV counselling and testing (HBHCT) programme was implemented in Bushenyi district of Uganda from 2004 to 2007. This programme provided free HBHCT services to all consenting adults of Bushenyi district and had a very high uptake and acceptability. We measured population-level changes in knowledge of HIV status, stigma and HIV-risk behaviours before and after HBHCT to assess whether widespread HBHCT had an effect on trends of risky sexual behaviours and on stigma and discrimination towards HIV. Serial cross-sectional surveys were carried out before and after the implementation of HBHCT programme in Bushenyi district of Uganda. A total of 1402 randomly selected adults (18 to 49 years) were interviewed in the baseline survey. After the implementation, a different set of randomly selected 1562 adults was interviewed using the same questionnaire. Data was collected on socio-demographic characteristics, sexual behaviour, whether respondents had ever tested for HIV and stigma and discrimination towards HIV/AIDS. The proportion of people who had ever tested for HIV increased from 18.6% to 62% (pstigma and discrimination. Because HBCT programmes are cost-effective, they should be considered for implementation in delivery of HIV services especially in areas where access to HCT is low.

    1995-01-01

    The serial changes in metabolism and histology during the first 24 hours in the cold-injury trauma rat brain model were investigated by proton magnetic resonance (MR) imaging and high-resolution proton MR spectroscopy. Edema developed extensively via the corpus callosum in the ipsi- and contralateral hemispheres during observation as shown by gradually increased signal intensity on proton MR images. Proton MR spectroscopy showed increased levels of acetate (Ace), lactate (Lac), and glutamine (Glmi) 1 hour after lesion formation. The elevated Glmi level slightly decreased, the level of alanine (Ala) increased substantially, and that of N-acetyl-aspartate (NAA) decreased markedly after 24 hours. Increased Lac, Ace, and Ala might reflect anaerobic glycolysis associated with mitochondrial dysfunction, while decreased Glmi and NAA reveal brain tissue breakdown. The relationship between brain edema and tissue viability can be analyzed in detail using this simple traumatic model and MR techniques which will be useful in the development of therapeutic agents for brain injury.

  2. A comparison of serial order short-term memory effects across verbal and musical domains.

    Science.gov (United States)

    Gorin, Simon; Mengal, Pierre; Majerus, Steve

    2018-04-01

    Recent studies suggest that the mechanisms involved in the short-term retention of serial order information may be shared across short-term memory (STM) domains such as verbal and visuospatial STM. Given the intrinsic sequential organization of musical material, the study of STM for musical information may be particularly informative about serial order retention processes and their domain-generality. The present experiment examined serial order STM for verbal and musical sequences in participants with no advanced musical expertise and experienced musicians. Serial order STM for verbal information was assessed via a serial order reconstruction task for digit sequences. In the musical domain, serial order STM was assessed using a novel melodic sequence reconstruction task maximizing the retention of tone order information. We observed that performance for the verbal and musical tasks was characterized by sequence length as well as primacy and recency effects. Serial order errors in both tasks were characterized by similar transposition gradients and ratios of fill-in:infill errors. These effects were observed for both participant groups, although the transposition gradients and ratios of fill-in:infill errors showed additional specificities for musician participants in the musical task. The data support domain-general serial order STM effects but also suggest the existence of additional domain-specific effects. Implications for models of serial order STM in verbal and musical domains are discussed.

  3. Postretention mandibular incisor stability after premolar serial extractions.

    1999-09-01

    The purpose of this study was to evaluate the mandibular incisor alignment in serial extraction cases, using the longitudinal dental cast records of the Burlington Growth Center as a control sample. Various parameters were investigated and the statistical differences determined between the treated and untreated groups. The results were also compared with data from serial extraction groups that subsequently had orthodontic treatment. Untreated subjects and subjects treated only with serial extractions showed similar longitudinal changes. However, the extraction group that also received orthodontic treatment appeared to show more lower incisor crowding long-term. No predictors for stability of clinical significance could be determined. Mechanotherapy influences the craniofacial and dentoalveolar dimensions, which appear to cause more long-term lower incisor crowding.

    Variations in treatment times for serial extraction and late premolar extraction patients may be due to differences in the time needed to flatten the occlusal curves. In this study, we compared tooth tipping and occlusal curves in patients treated by serial extractions or late premolar extractions with untreated controls. Mandibular dental casts and cephalometric radiographs were collected from 90 subjects (30 Class I control subjects, 30 patients with serial extractions, and 30 with late premolar extractions) at 3 time points: T0, baseline for the controls and serial extraction patients; T1, after natural drift and preorthodontics for the controls and the serial extraction patients, and pretreatment for the late premolar extraction patients; and T2, after comprehensive orthodontic treatment for the serial extraction and the late premolar extraction groups. The long axes of the central incisor, canine, and first molar to the palatal plane were measured on digitized headfilms to determine the direction and the amount of tipping between the time points. Three occlusal curves were measured by sphere fitting cusp-tip landmarks on digitized mandibular casts. From T0 to T1, incisors and canines in the patients with serial extractions tipped distally. Molars at T1 in the patients with serial extractions were tipped forward more than in the late premolar extraction patients and the controls. From T1 to T2, canines and molars in the patients with serial extractions were uprighted. Serial extractions produce steeper occlusal curves and distal tipping of the incisors and canines after drift (T1). Posttreatment (T2) occlusal curves in the patients with serial extractions are steeper than in the late premolar extraction patients and controls (except for the curve of Spee). After the serial extractions, orthodontic treatment included incisor and canine proclination, with molar uprighting and occlusal curve flattening.

    "Huntington Beach, California, is a popular surfing beach near Los Angeles. In July, 1999, the State of California instituted new beach cleanliness standards: beaches should be closed when bacterial concentrations exceed a certain amount. The beach promptly closed for two months. Local environmentalists blamed a nearby sewage outfall, prompting several million dollars worth of studies. How would you figure out whether the outfall was to blame, and what would you do about it?" From this starting point, my undergraduates work through the scientific, regulatory and policy issues involved in a decision about upgrading a coastal sewage outfall. They learn to interpret complex scientific data, discuss the role of science in policy and also reflect on their own priorities and decision-making processes. I will give a brief summary of my teaching methods, and provide CDs with HTML-based educational resources.

    Full Text Available This paper presents a case study which discusses the new meanings produced in the Federal Institute Sul-rio-grandense (IFSul curriculum policies. The use of Policy Cycle, as proposed by Ball, and the Discourse Theory (DT by Laclau, strengthened the analysis of meanings in a non-hierarchical way between the different contexts involved in the construction of such policies. In the process of analysing the MEC and IFSul official documents and interviews with managers and teachers from the institution, we decided to identify, assisted by the tool WordSmitht, meanings and displacements around the signifiers: teaching, research, extension and articulation. In this study, by exemplifying the DT concepts potential, the analysis of the signifier „extension‟ was carried out, which resulted in the perception that there is some difficulty to the fixation of meaning to this education dimension and that the managers‟ expectations, understood by the teachers, is that the latter are able to accomplish their tasks and achieve their objectives.

  10. The experience of parents of adult sons with Duchenne muscular dystrophy regarding their prolonged roles as primary caregivers: a serial qualitative study.

    Mechanical ventilation has allowed a greater number of patients with Duchenne muscular dystrophy (DMD) to transition into adulthood. However, the role of a child's parent as a caregiver lasts throughout the child's lifetime. We explored parents' experiences of prolonged caregiving using serial interviews, analyzed using constructivist grounded theory. Fourteen parents (average age 53.9 years) with sons with DMD (average age 23.2 years) were interviewed two to four times, over a 3-year period. Data were analyzed using a grounded theory approach. Two categories of responses were defined as strengths, and four as weaknesses. The strengths were related to family member support and confidence in parenting ability. The weaknesses were related to the anticipation of aging with the ongoing burden of caring for adult sons, regrets, sharing of responsibility versus having a fixed role as the primary caregiver, and economic burden. The weaknesses became more pronounced as the duration of caregiving increased. Parents' acceptance of and immobilization in their role of primary caregiver led to prolonged derivative dependency. Practical support for parental caregivers, who experience a marked increase in the duration of their caregiving role while facing their own aging-related challenges, are required. Implications for Rehabilitation Children with DMD are living longer and are transitioning into adulthood; a successful transition involves becoming as independent as possible and maintaining a positive sense of personal identity. Despite entering adulthood, the parental caregiver's caregiving role continues. Rehabilitation professionals, who are able to provide long-term, continued support from childhood into adulthood, should be aware that parental caregivers' weakness are exacerbated as the duration of caregiving increases. Families affected by DMD require multifaceted support that should include support for the parental caregiver.

    This study aims to analyses recent trends of international situation relating to nuclear non-proliferation and the adverse conditions in Korea's pursuing self-support of such technology, so that it may map out effective strategies for the promotion of nuclear energy. This study analyses developments of international nuclear non-proliferation regime, which plays a main role in preventing the international proliferation of nuclear weapons. This study includes NPT, IAEA safeguards system, international export control regimes, CTBT, and NWFZs as the subjects of analysis. Second theme is international organizations concerning nuclear activities. This study mainly analyses IAEA activities which pursues the promotion of peaceful use of nuclear energy and nuclear non-proliferation simultaneously as a pivotal body of international nuclear cooperation. Third focus of this study is Northeast Asian circumstances pertaining to nuclear non-proliferation. The study looks into the DPRK nuclear issues, and reviews the developments of the proposed regional body for nuclear cooperation and the discussion on the Northeast Asian NWFZ. Fourth, but the most influential to Korean nuclear activities, is the U. S. nuclear policy, since U. S. takes the overwhelming initiative in the field of international nuclear non-proliferation. Therefore, this study gives much weight in analyzing the structure, procedures, recent trend, and pending issues of U. S. nuclear policy. (author). 78 refs., 5 tabs., 4 figs

    Two patients with serologically confirmed herpes simplex encephalitis were studied by serial CT scannings. Case 1, a 60-year-old woman, was admitted to National Cardiovascular Center because of headache, fever, and attacks of Jacksonian seizure. Case 2, a 54-year-old man, was admitted because of fever, consciousness disturbance and right hemipare sis. Pleocytosis (mainly lymphocytes) and elevation of protein content in cerebrospinal fluid were observed in both cases. Both patients presented ''das apallische Syndrom'' one month after admission. The diagnosis of herpes simplex encephalitis was confirmed by typical clinical courses and by greater than fourfold rises in serum antibody titer for herpes simplex virus as well as that in cerebrospinal fluid in case 1. Characteristic CT findings observed in these two cases were summarized as follows: Within a week after the onset, no obvious abnormalities could be detected on CT scans (Case 1). Two weeks after the onset, a large low-density area appeared in the left temporal lobe and in the contralateral insular cortex with midline shift toward the right side (Case 2). One month later, an ill-defined linear and ring-like high-density area (Case 1), or a well-defined high-density area (Case 2), that was enhanced after contrast administration, was observed in the large low-density area in the temporal lobe. These findings were considered as characteristic for hemorrhagic encephalitis. These high-density areas disappeared two months later, however, widespread and intensified low-density areas still remained. In both cases, the basal ganglia and thalamus were completely spared on CT scans. From these observations, it can be concluded that serial CT scannings are quite useful for diagnosis of herpes simplex encephalitis. (author)

  20. Rethinking Study and Management of Agricultural Systems for Policy Design

    Directory of Open Access Journals (Sweden)

    Johann Baumgärtner

    2013-09-01

    Full Text Available There is a concern that agriculture will no longer be able to meet, on a global scale, the growing demand for food. Facing such a challenge requires new patterns of thinking in the context of complexity and sustainability sciences. This paper, focused on the social dimension of the study and management of agricultural systems, suggests that rethinking the study of agricultural systems entails analyzing them as complex socio-ecological systems, as well as considering the differing thinking patterns of diverse stakeholders. The intersubjective nature of knowledge, as studied by different philosophical schools, needs to be better integrated into the study and management of agricultural systems than it is done so far, forcing us to accept that there are no simplistic solutions, and to seek a better understanding of the social dimension of agriculture. Different agriculture related problems require different policy and institutional approaches. Finally, the intersubjective nature of knowledge asks for the visualization of different framings and the power relations taking place in the decision-making process. Rethinking management of agricultural systems implies that policy making should be shaped by different principles: learning, flexibility, adaptation, scale-matching, participation, diversity enhancement and precaution hold the promise to significantly improve current standard management procedures.

    Full Text Available This essay presents the discovery of the American serialization of Joseph Conrad’s Lord Jim in New York’s Evening Telegram in 1903. This ‘lost’ serialization, it argues, invites a new perspective on Conrad’s early career by foregrounding the role of newspaper serialization and syndication in establishing his literary standing. After surveying the principal differences in the respective reading experiences of the periodical versus the book, it concludes by proposing that the prominence of women among Conrad’s first audiences requires us to reassess the basis for his success in North America and elsewhere.

    This document presents a case study of energy policies in Texas related to power system transformation, renewable energy and distributed energy resources (DERs). Texas has experienced a dramatic increase in installed wind capacity, from 116 MW in 2000 to over 15,000 MW in 2015. This achievement was enabled by the designation of Competitive Renewable Energy Zones (CREZs) and new transmission lines that transmit wind to load centers. This report highlights nascent efforts to include DERs in the ERCOT market. As costs decline and adoption rates increase, ERCOT expects distributed generation to have an increasing effect on grid operations, while bringing potentially valuable new resources to the wholesale markets.

In Brazil, the most prominent network in recent years is Facebook, which reached 76 million users in June 2013, an unprecedented number in the country. The growth allowed governments to perceive this virtual space as a potential place to present their work and communicate with society. Objectives: The study goal is to observe how information has been publicized by the Ministry of Health through Facebook since 2010 (year of creation of the page until October 2013, taking as an analytical category the implemented information policy, in order to propose a discussion about democratization of access to health information. Methodology: case study; Non-participant observation, data collection and documental analysis. Results: The main issues addressed by the Ministry of Health on Facebook are organizational actions and government programs instead of posts with guidance for a healthy living style. Also noteworthy is the low interaction of the Ministry page moderators with the users profile. The study showed most of the questions and comments made by the public are not answered by the institutional body. Conclusions: Need of strengthening the mediaton process of the information policies from the Ministry of Health on Facebook.

    Full Text Available A main objective of European governments is to reduce the number of early retirees, either by reforming pension systems or promoting active aging in working life. The importance of formulating a coherent personnel policy for all age groups is increasingly recognized by employers. However, there is still a lack of knowledge as how to strategically cope with an aging labor force. The aim of this article is to define and discuss a number of challenges arising from workplace-related active aging policies. We in particular discuss how an emphasis on economic incentives and gains (“senior goods” may give rise to unanticipated side effects for the employers as well as the employees. The article is based on results from two recent studies: one study examining six Norwegian municipalities with seemingly good practices in work-related old age policies, and another examining such policies in eight establishments in four different industries.

    Full Text Available The Internet development has brought both new opportunities and risks for either retailers or consumers. For example, electronic commerce is much faster and less expensive, but this openness makes it difficult to secure. People are aware of the fact that online businesses collecting, process and distribute enormous amounts of personal data and therefore, are concerned about their unauthorized use or their use in other purposes than intended by third parties in order to gain unauthorized access to them. There are more examples of cyber criminal activities, such as: hacking, software piracy, passwords attack, service prohibition attacks, scamming, etc. Such fears led to the editing of protection policies meant to secure personal data and to develop some mechanisms to ensure the reliability and confidentiality of electronic information. Security measures include access control devices, installation of firewalls and intrusion detection devices, of some security procedures to identify and authenticate authorized users of network systems. Such mechanisms constitute the core of this study. We will also analyze security and confidentiality policy of personal data of Google Inc.

    Silva, J Arturo; Ferrari, Michelle M; Leong, Gregory B

    2002-11-01

    Sexual serial homicidal behavior has received considerable attention during the last three decades. Substantial progress has been made in the development of methods aimed at identifying and apprehending individuals who exhibit these behaviors. In spite of these advances, the origins of sexual serial killing behavior remain for the most part unknown. In this article we propose a biopsychosocial psychiatric model for understanding the origins of sexual serial homicidal behavior from both neuropsychiatric and developmental perspectives, using the case of convicted serial killer Jeffrey Dahmer as the focal point. We propose that his homicidal behavior was intrinsically associated with autistic spectrum psychopathology, specifically Asperger's disorder. The relationship of Asperger's disorder to other psychopathology and to his homicidal behavior is explored. We discuss potential implications of the proposed model for the future study of the causes of sexual serial homicidal crime.

    2001-01-01

    The prime ministers of North Korea and South Korea adopted 'Joint Declaration of the Denuclearization of the Korean Peninsular' (Joint Declaration) on December 31, 1991. Unprecedented as an agreement between two political powers of a divided country, this Joint Declaration is important for its historical significance. To analyze the denuclearization policy in the Korean peninsular, this dissertation suggests a framework which can be established on the factors facilitating the denuclearization both on the level of international politics and on the politics of a divided country. A substantial nuclear proliferation theory should be based on the study in detail of the nuclear proliferation cases of about 40 individual countries. This dissertation may be meaningful as a concrete study of the denuclearzation in the Korean peninsular on theoretical and practical basis

    In the advanced countries, there are active studies on biocide, implying non-agricultural pesticides, at present with increasing interests on this. Among the advanced countries, Canada, Australia and New Zealand are managing biocides the most systematically and have very clear regulations and roles of relevant departments. In addition to efforts of each country, the international organizations are emphasizing the need of biocides management. EU already announced Biocidal Products Directive(BPD) in 1998 and is urging to implement regulations within a guidebook in member countries from 2000. Furthermore, OECD is well aware of biocides management trend of each member country and is planning to set up a specific management guide based on this. In this study, it recommends a biocides management policy in Korea with regulations, relevant departments, and regulation contents of biocides implemented in the advanced countries and regulation trend of biocides in Korea. 47 refs., 27 tabs.

    2000-10-01

    The problem of site allocation on locally unwanted land uses related to energy utilities that extended most recently is becoming a new energy policy issue due to the improvement of national standard of living and livelihood quality. Residents do not generally agree on establishing the construction of public energy utilities in their village due to NIMBY syndrome while they basically agree to have them. These circumstances made a big problem against mass production of industry society and the improvement of the national welfare. Locally unwanted land use related to energy utilities includes waste incineration system, nuclear power plant, coal fired power plant, oil and Gas storage tank, briquette manufacturing plant and etc. Opportunity for SOC projects carried out by central and local government is lost because of the regional egoism. The site dispute between government and residents obstructs optimal energy supply to be necessary for industry growth and the national welfare. The main objective of this study is to propose the policy option for finding a solution after surveying theory and background of site troubles and dispute factors. Final results of this study propose a solution on structural and institutional dispute. The former introduces three kinds of approaches such as tradition, compensation and negotiation. The transition of an environmentally sound energy consumption pattern and the improvement of energy efficiency could be carried out by traditional approaches. To claim the damage and offer the accommodation facilities could be settled by compensational approaches. The establishment of regional decentralization on NIMBY facilities could be settled by negotiatory approaches through fair share criteria. The latter proposes 1) 'polluter pays principle', 2) internalization of social cost and benefit on air or water pollution, 3) the behind - the - scene negotiation in a bid to settle a site dispute, 4) and supporting system for peripheral areas

    Accurate and consistent skull stripping of serial brain MR images is of great importance in longitudinal studies that aim to detect subtle brain morphological changes. To avoid inconsistency and the potential bias introduced by independently performing skull-stripping for each time-point image, we propose an effective method that is capable of skull-stripping serial brain MR images simultaneously. Specifically, all serial images of the same subject are first affine aligned in a groupwise manner to a common space to avoid any potential bias introduced by asymmetric transforms. A brain probability map, which encapsulates prior information gathered from a population of real brain MR images, is then warped to the aligned serial images for guiding skull-stripping via a deformable surface method. In particular, the same initial surface meshes representing the initial brain surfaces are first placed on all aligned serial images, and then all these surface meshes are simultaneously evolved to the respective target brain boundaries, driven by the intensity-based force, the force from the probability map, as well as the force from the spatial and temporal smoothness. Especially, imposing the temporal smoothness helps achieve longitudinally consistent results. Evaluations on 20 subjects, each with 4 time points, from the ADNI database indicate that our method gives more accurate and consistent result compared with 3D skull-stripping method. To better show the advantages of our 4D brain extraction method over the 3D method, we compute the Dice ratio in a ring area (±5mm) surrounding the ground-truth brain boundary, and our 4D method achieves around 3% improvement over the 3D method. In addition, our 4D method also gives smaller mean and maximal surface-to-surface distance measurements, with reduced variances.

    Tobacco control policies reduce the health and economic burden caused by tobacco. With over half of the United States communities lacking adequate protective policies, an examination of policy adoption factors can provide insights to facilitate policy adoption. A case study approach examines the rate of adoption, prominent media frames, policy leaders' perceptions and coalition activities for smokefree and Tobacco 21 policies adopted in Missouri. Findings show compared to smokefree policy, Tobacco 21 requires a considerably shorter timeframe and fewer resources for adoption. Tobacco 21 coalitions target a small group of stakeholders compared to smokefree coalitions' emphasis on broad community engagement. Both policies are formally opposed, but elected officials perceive less political risk supporting Tobacco 21. As a new tobacco control policy tool, Tobacco 21 has relative advantage that should be considered by community health advocates.

  1. Energy Policy in the Baltics: A Study of Regional Cooperation

    Parks, Jessica Annette

    Regionalism, especially in the form of macro-regions, has emerged as a force of cooperation and integration within the European Union. The Baltic states, who have cooperated more closely since acceding to the EU, provide an effective case study for testing the unifying power of regionalism. As small states that have shared a damaging dependence on Russian energy imports, the three Baltic states share the incentive to cooperate as a region and develop their internal gas, oil, and electricity capacities. The Baltic states have displayed uneven tendencies of cooperation when it comes to energy, however. After presenting an overview of regionalism in the EU, this paper examines EU policy regarding energy in the Baltics, energy ties between the Baltics and other countries, and specific energy projects in the Baltics to show that while the Baltics do not yet have a strong tradition of cooperation in the energy sector, they have laid the groundwork to strengthen future ties.

Is a qualitative study that the procedures for its development ranks as literature and documents. The data collection technique was documentary and had as a data source primary and secondary documents, coming from public archives and statistical sources. For the survey of brazilian data for the development of this study, it was used as informational basis the fifth edition of the Innovation Research (PINTEC 2011. The data from France raised through the use of OECD year Report 2014 " Reviews of Innovation Policy France in 2014."  For the presentation of the study results comparative charts and tables were used. As the present study results can be highlighted, among others: France is a country with a long scientific tradition and technique, and plays a significant role in the world in this area. On the other hand, Brazil has one of the lowest proportions of R&D and export of high technology to GDP. The completion of this study brought an important diagnosis: there is a wide and interesting research topic that is still little explored by Brazilian researchers.

    Seasonal influenza vaccination offers one of the best population-level protections against influenza-like illness (ILI). For most people, a single dose prior to the flu season offers adequate immunogenicity. HIV+ patients, however, tend to exhibit a shorter period of clinical protection, and therefore may not retain immunogenicity for the entire season. Building on the work of Nosyk et al. (2011) that determined a single dose is the optimal dosing strategy for HIV+ patients, we investigate the optimal time to administer this vaccination. Using data from the "single dose" treatment arm of an RCT conducted at 12 CIHR Canadian HIV Trials Network sites we estimated semimonthly clinical seroprotection levels for a cohort (N=93) based on HAI titer levels. These estimates were combined with CDC attack rate data for the three main strains of seasonal influenza to estimate instances of ILI over different vaccination timing strategies. Using bootstrap resampling of the cohort, nine years of CDC data, and parameter distributions, we developed a Markov cohort model that included probabilistic sensitivity analysis. Cost, quality adjusted life-years (QALYs), and net monetary benefits are presented for each timing strategy. The beginning of December is the optimal time for HIV+ patients to receive the seasonal influenza vaccine. Assuming a willingness-to-pay threshold of $50,000, the net monetary benefit associated with a Dec 1 vaccination date is $19,501.49 and the annual QALY was 0.833744. Our results support a policy of administering the seasonal influenza vaccination for this population in the middle of November or beginning of December, assuming nothing is know about the upcoming flu season. But because the difference in between this strategy and the CDC guideline is small-12 deaths averted per year and a savings of $60 million across the HIV+ population in the US-more research is needed concerning strategies for subpopulations.

    The objectives of this study is to provide recommendations for formulating adequate policy and strategies for IAEA-TC programme as being of a donor Member State and to guide directions to facing the challenges of changing the status from IAEA-TC recipient to donor country. In addition, this study gives recommendations and feedbacks to the IAEA-TC programmer: how it has contributed to nation's nuclear technology development in the past on one hand and how the country has contributed to it on the other. Besides, this study also conducted to identify the following impacts expected: termination of on-going National TC projects, discontinuation of TC-based technical advices, sponsored fellowship and scientific visits for capacity building opportunities, and limitation in participations of various regional projects due to termination of IAEA financial support. In terms of financial aspect, this study has also performed to assess the nation's annual financial contribution (Technical Cooperation (TC) Fund: 1,67 million dollars in 2008) by comparing the experiences of other OECD countries cases. In conclusion, it is expected that the results of this study will contribute to develop appropriate measures in order to maximize the benefits for future national nuclear technology development and in addition, to explore the possibilities to extend the nuclear technology export market potentials

  8. Evaluation of energy efficiency policy instruments effectiveness : case study Croatia

    Bukarica, V.

    2007-01-01

    This paper proposed a theoretical basis for evaluating energy efficiency policy in the Republic of Croatia and corroborated it with the analysis of energy efficiency market development and transformation. The current status of the market was evaluated and policy instruments were adapted to achieve optimal results. In particular, the energy efficiency market in Croatia was discussed in terms of micro and macro environment factors that influence policy making processes and the choice of policy instruments. The macro environment for energy efficiency market in Croatia is the process of European Union pre-integration with all related national and international legislation, political and economical factors and potential to use financial funds. The micro environment consists of government institutions, local financing institutions and a range of market players on the supply and demand side. Energy efficiency is the most powerful and cost-effective way for achieving goals of sustainable development. Policy instruments developed to improve energy efficiency are oriented towards a cleaner environment, better standard of living, more competitive industry and improved security of energy supply. Energy efficiency is much harder to implement and requires policy interventions. In response to recent trends in the energy sector, such as deregulation and open competition, policy measures aimed at improving energy efficiency should shift from an end-users oriented approach towards a whole market approach. The optimal policy instruments mix should be designed to meet defined targets. However, market dynamics must be taken into consideration. 9 refs., 4 figs

  9. Toward a Theoretical Framework for Studying Climate Change Policies: Insights from the Case Study of Singapore

    2017-07-01

    Full Text Available The world decided in December 2015 to take actions to reduce global warming. To contribute toward this goal, this research examines possible policy levers for inclusion in the climate change ratification plan. A case study of the measures taken by the Republic of Singapore, a low-lying 719.2 km2 island without natural resources in Asia, is conducted. Being vulnerable to climate change impact and yet having to balance her people’s needs and economic progress with limited resources, the measures taken by this small country could offer policy insights for small states and states without access to alternative energy sources. This research analyzes the online policy documents posted by eleven organizations to answer the main research question of identifying policy levers as theoretical constructs to form a framework that can be used to study climate change policies. A qualitative data analysis software, QSR NVivo 10, is used to classify the proposed nodes developed by the researchers using a system perspective integrating the insights from the key international climate change frameworks with the theoretical concepts from the model of pro-environmental behavior. The findings can offer insights toward developing a new contextual influence framework, which can help strengthen policy development and outcome measurement.

    Full Text Available Background & objective: Good examples of evidence generation using Health Policy and Systems Research (HPSR in low and middle income countries (LMIC; and its application in policy making are scarce. In this paper, we describe the experience of establishing a system of HPSR from the Haryana state in India, outline how the HPSR is being utilized for policy making and programmatic decision making, and analyse the key factors which have been critical to the implementation and uptake of HPSR. Methods: Multiple methods are employed in this case study, ranging from unstructured in-depth interviews, review of the program and policy documents, and participatory notes from the meetings. The steps towards creation of a knowledge partnership between stakeholders are outlined. Four case studies i.e. development of a plan for universal health care (UHC, nutrition policy, centralized drug procurement system and use of RAPID appraisal method highlight the use of research evidence in agenda setting, policy formulation and policy implementation respectively. Results: Our analysis shows that the most important factor which contributed to Haryana model of HPSR was the presence of a dedicated and motivated team in National Rural Health Mission (NRHM at state level, many of whom were researchers by previous training. Overall, we conclude by highlighting the need for establishing an institutional mechanism at Central and State level where health service administrators and managers, academicians and researchers working in the field of health system from medical colleges, public health schools, management and technology institutions and social science universities can identify health system research priorities. Increased budgetary allocation for HPSR is required.

    Critical discourse analysis (CDA) is a promising methodology for policy research in nursing. As a critical theoretical methodology, researchers use CDA to analyze social practices and language use in policies to examine whether such policies may promote or impede social transformation. Despite the widespread use of CDA in other disciplines such as education and sociology, nursing policy research employing CDA methodology is sparse. To advance CDA use in nursing science, it is important to outline the overall research strategies and describe the steps of CDA in policy research. This article describes, using exemplar case studies, how nursing and health policy researchers can employ CDA as a methodology. Three case studies are provided to discuss the application of CDA research methodologies in nursing policy research: (a) implementation of preconception care policies in the Zhejiang province of China, (b) formation and enactment of statewide asthma policy in Washington state of the United States, and (c) organizational implementation of employee antibullying policies in hospital systems in the Pacific Northwest of the United States. Each exemplar details how CDA guided the examination of policy within specific contexts and social practices. The variations of the CDA approaches in the three exemplars demonstrated the flexibilities and potentials for conducting policy research grounded in CDA. CDA provides novel insights for nurse researchers examining health policy formation, enactment, and implementation. © The Author(s) 2016.

    Evidence has come to play a central role in health policymaking. However, policymakers tend to use other types of information besides research evidence. Most prior studies on evidence-informed policy have focused on the policy formulation phase without a systematic analysis of its implementation. It has been suggested that in order to fully understand the policy process, the analysis should include both policy formulation and implementation. The purpose of the study was to explore and compare two policies aiming to improve health and social care in Sweden and to empirically test a new conceptual model for evidence-informed policy formulation and implementation. Two concurrent national policies were studied during the entire policy process using a longitudinal, comparative case study approach. Data was collected through interviews, observations, and documents. A Conceptual Model for Evidence-Informed Policy Formulation and Implementation was developed based on prior frameworks for evidence-informed policymaking and policy dissemination and implementation. The conceptual model was used to organize and analyze the data. The policies differed regarding the use of evidence in the policy formulation and the extent to which the policy formulation and implementation phases overlapped. Similarities between the cases were an emphasis on capacity assessment, modified activities based on the assessment, and a highly active implementation approach relying on networks of stakeholders. The Conceptual Model for Evidence-Informed Policy Formulation and Implementation was empirically useful to organize the data. The policy actors' roles and functions were found to have a great influence on the choices of strategies and collaborators in all policy phases. The Conceptual Model for Evidence-Informed Policy Formulation and Implementation was found to be useful. However, it provided insufficient guidance for analyzing actors involved in the policy process, capacity-building strategies

    Recent reports have revealed that motor skill learning is impaired if two skills are practiced one after the other, that is before the first skill has had the time to become consolidated. This suggests that motor skills should be practiced in isolation from one another to minimize interference. At the moment, little is known about the effect of practice schedules high in contextual interference on motor skill consolidation. In Experiment 1, we investigated whether a serial practice schedule impairs motor skill consolidation. Participants had to learn two distinct sequences of finger movements (A and B) under either a blocked practice schedule or a serial practice schedule before being retested the following day. A control group also practiced Sequence A only. Our results revealed that a blocked practice schedule led to no interference between the sequences, whereas a serial practice schedule impaired the consolidation of Sequence B. In Experiment 2, we investigated the origin of the interference caused by a serial practice schedule by replacing the physical practice of Sequence A with either the observation of a model performing Sequence A or by asking participants to produce random finger movements. Our results revealed that both tasks interfered with the consolidation of Sequence B. Thus, we suggest that a serial practice schedule impairs motor skill consolidation through a conflict in the brain networks involved in the acquisition of the cognitive representation of the sequence and its execution.

    Recent research in attentional focus of instruction has predominantly over-emphasized the investigation of discrete and continuous skills rather than serial skills. The purpose of this study was therefore to examine the effect of different attentional focus instructions on learning a serial skill task (i.e., taekwondo routine) in novice learners. It was predicted that the use of movement outcome instructions could enhance the learning of a serial skill as previously supported in studies examining the acquisition of discrete and continuous skills. Thirteen female participants were recruited for this study and were assigned to either movement form condition - control group (n = 7) or movement outcome condition - treatment group (n = 6). All participants underwent 12 practice sessions over an 8-week period with their respective instructional conditions with each session lasting 30 minutes. Video recording of the serial skill tasks (hand techniques, kicking techniques and 10-step routine) were captured at "the-twelfth-training session", "after 1-week", and "after 1-month". It was found that more participants in the treatment group obtained a higher score in all three serial skill tasks, especially in Mastery component of 'Kicking' techniques at 'after 1-week' (p movement outcome instructions have positive medium effect on balance control for serial skill task, especially in kicking actions.

    This article addresses the vocabulary of cross-national analysis and commentary about health care, health policy and health politics. We conclude there is a large gap between promise and performance in comparative policy commentary and point to major sources of confusion, such as the lack of generally agreed vocabulary, vague language and the use of faddish and misleading terms and aspirational labels (illustrated by a selection of widely used expressions in comparative reports). We next examine the basic purposes of international policy comparison, distinguish three useful and two misleading approaches and frame defensible ground rules for comparative work.

    No consensus has been reached with regard to the ideal timing of anterior cruciate ligament reconstruction in terms of reducing secondary meniscal tears in anterior cruciate ligament-deficient knees. Delay in anterior cruciate ligament reconstruction increases the incidence and severity of medial meniscal tears. Case series; Level of evidence, 4. Thirty-one patients were evaluated with arthroscopic all-inside suturing of medial meniscal tears with concurrent anterior cruciate ligament reconstruction who had at least 2 preoperative magnetic resonance imaging studies. Patients were evaluated during the acute phase of injury, but anterior cruciate ligament reconstruction surgery was delayed at least 6 months. Mean interval between first and second imaging studies was 36.8 months. Subsequent medial meniscal tears were identified as longitudinal or bucket-handle types. Relationships between medial meniscal lesions and patient age, time interval between the date of initial injury and surgery, repetitive injury, and patient activity level were evaluated. During the first preoperative magnetic resonance imaging studies, 14 knees had no medial meniscal tear, 15 a longitudinal tear, and 2 a bucket-handle-type tear; during the second preoperative imaging studies, 5 knees had no medial meniscal tear, 19 a longitudinal tear, and 7 a bucket-handle-type tear. The incidence of medial meniscal tears increased from 55% in first studies to 84% in second studies for chronic anterior cruciate ligament-insufficient knees (P = .0054). Eight knees without a tear during first studies had a longitudinal tear during second studies, 1 knee without a tear and 4 with a longitudinal tear in first studies had a bucket-handle-type tear in second studies. Thirteen knees (42%) had a worse meniscal status during the second studies. Delayed anterior cruciate ligament reconstruction increases the likelihood of a medial meniscal tear, suggesting that early anterior cruciate ligament reconstruction

    Nicaragua, situated at the Central American Subduction zone and placed in the trajectory of tropical storms and hurricanes, is a frequent showplace of natural disasters which have multiplied the negative effects of a long term socioeconomic crisis leaving Nicaragua currently as the second poorest country of the Americas. In the last years, multiple efforts were undertaken to prevent or mitigate the affectation of the natural phenomena to the country. National and local authorities have become more involved in disaster prevention policy and international cooperation boosted funding for disaster prevention and mitigation measures in the country. The National Geosciences Institution (INETER) in cooperation with foreign partners developed a national monitoring and early warning system on geological and hydro-meteorological phenomena. Geological and risk mapping projects were conducted by INETER and international partners. Universities, NGO´s, International Technical Assistance, and foreign scientific groups cooperated to capacitate Nicaraguan geoscientists and to improve higher education on disaster prevention up to the master degree. Funded by a World Bank loan, coordinated by the National System for Disaster Prevention, Mitigation and Attention (SINAPRED) and scientifically supervised by INETER, multidisciplinary hazard and vulnerability studies were carried out between 2003 and 2005 with emphasis on seismic hazard. These GIS based works provided proposals for land use policies on a local level in 30 municipalities and seismic vulnerability and risk information for each single building in Managua, Capital of Nicaragua. Another large multidisciplinary project produced high resolution air photos, elaborated 1:50,000 vectorized topographic maps, and a digital elevation model for Western Nicaragua. These data, integrated in GIS, were used to assess: 1) Seismic Hazard for Metropolitan Managua; 2) Tsunami hazard for the Pacific coast; 3) Volcano hazard for Telica

    Here, a new time averaging circuit design, the 'parallel filter' is presented, which can reduce the time jitter, introduced in time measurements using counters of large dimensions. This parallel filter could be considered as a single stage unit circuit which can be repeated an arbitrary number of times in series, thus providing a parallel-serial filter type as a result. The main advantages of such a filter over a serial one are much less electronic gate jitter and time delay for the same amount of total time uncertainty reduction. (orig.)

    Mild cognitive impairment (MCI) is often associated with the preclinical phase of Alzheimer's disease (AD). Special scoring of word-list recall data for serial position has been suggested to improve discrimination of normal aging from dementia. We examined serial position effects in word-list recall for MCI participants compared to Alzheimer patients and controls. Individuals with MCI, like Alzheimer patients, had a diminished primacy effect in recalling words from a list. No alternative scoring system was better than standard scoring of word-list recall in distinguishing MCI patients from controls. Retention weighted scoring improved the discrimination of MCI and AD groups.

    Anthropogenic activity will bring immediate changes and disruptions to the global climate with accompanying health implications. Although policymakers and public health advocates are beginning to acknowledge the health implications of climate change, current policy approaches are lagging behind. We proposed that 4 key policy principles are critical to successful policymaking in this arena: mainstreaming, linking mitigation and adaptation policy, applying population perspectives, and coordination. We explored California's progress in addressing the public health challenges of climate change in the San Joaquin Valley as an example. We discussed issues of mental health and climate change, and used the San Joaquin Valley of California as an example to explore policy approaches to health issues and climate change. The California experience is instructive for other jurisdictions. (Am J Public Health. Published online ahead of print October 26, 2017: e1-e6. doi:10.2105/AJPH.2017.304047).

  5. Modified Policy-Delphi study for exploring obesity prevention priorities.

    2016-09-06

    Until now, industry and government stakeholders have dominated public discourse about policy options for obesity. While consumer involvement in health service delivery and research has been embraced, methods which engage consumers in health policy development are lacking. Conflicting priorities have generated ethical concern around obesity policy. The concept of 'intrusiveness' has been applied to policy decisions in the UK, whereby ethical implications are considered through level of intrusiveness to choice; however, the concept has also been used to avert government regulation to address obesity. The concept of intrusiveness has not been explored from a stakeholder's perspective. The aim is to investigate the relevance of intrusiveness and autonomy to health policy development, and to explore consensus on obesity policy priorities of under-represented stakeholders. The Policy-Delphi technique will be modified using the James Lind Alliance approach to collaborative priority setting. A total of 60 participants will be recruited to represent three stakeholder groups in the Australian context: consumers, public health practitioners and policymakers. A three-round online Policy-Delphi survey will be undertaken. Participants will prioritise options informed by submissions to the 2009 Australian Government Inquiry into Obesity, and rate the intrusiveness of those proposed. An additional round will use qualitative methods in a face-to-face discussion group to explore stakeholder perceptions of the intrusiveness of options. The novelty of this methodology will redress the balance by bringing the consumer voice forward to identify ethically acceptable obesity policy options. Ethical approval was granted by the Bond University Health Research Ethics Committee. The findings will inform development of a conceptual framework for analysing and prioritising obesity policy options, which will be relevant internationally and to ethical considerations of wider public health issues

    Myocardial perfusion imaging (MPI) with gated single-photon emission tomography provides important information on the extent and severity of myocardial perfusion abnormalities, including myocardial ischemia. The availability of software for automated quantitative assessment of myocardial perfusion in an objective and more reproducible manner than visual assessment has allowed MPI to be particularly effective in serial evaluation. Serial testing using MPI is widely used in guiding patient care despite the lack of well-defined appropriateness use criteria. This should not be surprising because ischemic heart disease is a life-long malady subject to dynamic changes throughout its natural course and particularly following man-made interventions that may improve or worsen the disease process, such as medical therapy and coronary revascularization. Serial MPI has filled an important clinical gap by providing crucial information for managing patients with changes in clinical presentations or in anticipation of such changes in patients with stable symptoms. In the research arena, serial MPI has been widely applied in randomized controlled trials to study the impact of various medical and interventional therapies on myocardial perfusion, as well as the relative merits of new imaging procedures (hardware and/or software), radiotracers, and stressor agents. Serial testing, however, unlike initial or 1-time testing, has more stringent requirements and is subject to variability because of technical, procedural, interpretational, and biological factors. The intrinsic variability of MPI becomes important in interpreting serial tests in order to define a true change in a given patient and to guide clinical decision making. The purpose of this first comprehensive review on this subject is to illustrate where serial MPI may be useful clinically and in research studies, and to highlight strategies for addressing the various issues that are unique to serial testing in order to derive

    Full Text Available The purpose of this study is to discover the values of education in the novels "Series of Anak-anak Mamak" by Tere Liye. The novels are more appropriately analyzed by using structural semiotic studies because the sentences used in the author of four novels consist of language styles and idioms. "Series of Anak-anak Mamak" also contain quite a lot of educational values. This study used a qualitative approach with content analysis method. The focus of the research is: the value of education in terms of structural and semiotic theories contained in the novels "Series of Anak-anak Mamak". The finding of this study is a description of the values of education in the novels entitled "Eliana", "Pukat", "Burlian" and "Amelia" by using a semiotic approach. The whole chapters in the four novels contain the values of education when viewed from the structural theory. Total percentage of the values of education contained in the four novels are: (1 honesty amounted to 18.33%, (2 fidelity amounted to 12.50%, (3 tolerance amounted to 8.33%, (4 confidence amounted to 47.50%, and (5 affection amounted to 13.33%. Semiotic studies in this novel are based on the styles of language and idioms, included connotative meanings. The whole chapters in the novel contain the values of education from the semiotic standpoint. Total percentage of the values of education from the semiotic standpoint of the four novels are: styles of language amounted to 57.25% and idioms amounted to 42.75%.

    Whether the serial features found in some molluscs are ancestral or derived is considered controversial. Here, in situ hybridization and antibody studies show iterated engrailed-gene expression in transverse rows of ectodermal cells bounding plate field development and spicule formation in the chiton, Lepidochitona cavema, as well as in cells surrounding the valves and in the early development of the shell hinge in the clam, Transennella tantilla. Ectodermal expression of engrailed is associated with skeletogenesis across a range of bilaterian phyla, suggesting a single evolutionary origin of invertebrate skeletons. The shared ancestry of bilaterian-invertebrate skeletons may help explain the sudden appearance of shelly fossils in the Cambrian. Our interpretation departs from the consideration of canonical metameres or segments as units of evolutionary analysis. In this interpretation, the shared ancestry of engrailed-gene function in the terminal/posterior addition of serially repeated elements during development explains the iterative expression of engrailed genes in a range of metazoan body plans.

    A plan for actively achieving green energy obligation is a strategic tool for policies that point forward the diminution of the fossil fuel consumption and greenhouse gas (GHG) in conformity with the Paris environment-friendly accords (COP21) and updates of other ecosystem agreements. To achieve the concrete implementation of the sustainable energy strategy (SES) and to accomplish its objectives, an investigation is a critical factor. SES investigation has to consider both the advancement of each particular action and its wide-ranging green effect, which necessitates multiple levels of improvement. In this study, a consolidated eco strategy for evaluating, monitoring and handling the SES via investigation and execution process is established. The city of Nairobi was used as one of the geographical positions to test the effectiveness of this approach and to investigate its robust and weak points. Specifically, benefit-cost analysis, reliability, peer review and general level of participation were renowned as vital tools for attaining a functional SES investigation and for then drafting successful energy guidelines. Some suggestions were put forward to highlight the research and execution methods and to draw a road map of how SES can be strategically placed into practice.

    Biochemical markers of acute neuronal injury may aid in the diagnosis and management of acute ischemic stroke. Serum samples from the National Institute for Neurological Disorders and Stroke (NINDS) recombinant tissue plasminogen activator Stroke Study were analyzed for the presence of 4 biochemical markers of neuronal, glial, and endothelial cell injury. These biochemical markers, myelin basic protein (MBP), neuron-specific enolase (NSE), S100beta, and soluble thrombomodulin, were studied for an association with initial stroke severity, infarct volume, and functional outcome. In the original NINDS study, serum samples were drawn from all patients on presentation to the Emergency Department and at approximately 2 and 24 hours after initiation of study therapy. In this analysis, stored serum samples were available for 359 patients; 107 patients had samples for all 3 time points. Serum marker concentrations were measured by ELISA techniques. We examined the relation between serum concentrations of each marker and the degree of baseline neurological deficit, functional outcome, and infarct size on computed tomography at 24 hours and the effect of fibrinolytic therapy. Higher 24-hour peak concentrations of MBP, NSE, and S100beta were associated with higher National Institutes of Health Stroke Scale baseline scores (r=0.186, P<0.0001; r=0.117, P=0.032; and r=0.263, P<0.0001, respectively). Higher peak concentrations of MBP and S100beta (r=0.209, P<0.0001; r=0.239, P<0.0001) were associated with larger computed tomography lesion volumes. Patients with favorable outcomes had smaller changes in MBP and S100beta (P<0.05) concentrations in the first 24 hours. Soluble thrombomodulin was not associated with any severity or outcome measure. This study corroborates previous work demonstrating correlations of MBP, NSE, and S100beta with clinical and radiographic features in acute stroke. Despite significantly better outcomes in the tissue plasminogen activator-treated group, we

  14. Rethinking Conceptual Definitions of the Criminal Career and Serial Criminality.

    2016-01-01

    Since Cesare Lombroso's days, criminology seeks to define, explain, and categorize the various types of criminals, their behaviors, and motives. This aim has theoretical as well as policy-related implications. One of the important areas in criminological thinking focuses chiefly on recidivist offenders who perform large numbers of crimes and/or commit the most dangerous crimes in society (rape, murder, arson, and armed robbery). These criminals have been defined as "habitual offenders," "professional criminals," "career criminals," and "serial offenders." The interest in these criminals is a rational one, given the perception that they present a severe threat to society. The main challenge in this area of research is a conceptual problem that has significant effects across the field. To this day, scholars have reused and misused titles to define and explain different concepts. The aim of this article is 3-fold. First, to review the concepts of criminal career, professional crime, habitual offenses, and seriality with a critical attitude on confusing terms. Second, to propose the redefinition of concepts mentioned previously, mainly on the criminal career. Third, to propose a theoretical model to enable a better understanding of, and serve as a basis for, further research in this important area of criminology. © The Author(s) 2015.

    2001-10-01

    Bluetooth is a new short-range wireless communication technology developing rapidly in recent years. Bluetooth software architecture consists of stack and profiles. Serial Port Profile (SPP) is an underlying profile that emulates RS232 serial cable connections between two peer devices. Based on SPP, Dial-up Networking (DUN) Profile establishes PPP connection with remote dial-up server, Fax Profile realizes document facsimile function and LAN Access Profile (LAP) provides local area network access service. When it comes to their implementation in embedded systems, there are several challenges such as memory consumption, code efficiency, code reliability, and code portability onto different OS and hardware platforms to be attacked. In this paper, we propose integrated software architecture after discussing the great similarities shared among the three SPP based profiles. Then implementation of the architecture is given, in which OS-dependent and OS-independent parts are clearly separated. Profile interfaces with stack and OS are specified respectively so that the three profiles as a whole can be ported onto various software and hardware platforms easily. As a result, policy of transplanting our implementation onto different platforms is addressed at the end of the paper.

    Matrix-assisted laser desorption/ionization mass spectrometry imaging is an emerging powerful technique in drug metabolism and pharmacokinetics research. Despite recent progress in mass-spectrometry-based localization and relative quantification of small-molecule drugs and their metabolites in tissue, improved methods for drug extraction/ionization are required. Furthermore, relative quantification of drugs by mass spectrometry imaging in larger rodent cohorts is a necessary proof-of-concept study to demonstrate the utility of such a workflow in an industrial setting. Using as an example the tyrosine kinase inhibitor dasatinib, a leukemia drug, we demonstrate that inclusion of dimethyl sulfoxide in standard matrix solutions significantly improves ion intensity in mass spectrometry images and reveals enrichment of the drug in mouse kidney medulla. We furthermore show in a time-course study in multiple mice that normalization against a deuterated internal standard, dasatinib-D8, which is applied together with the matrix, makes possible relative quantification of the drug that correlates well with canonical liquid chromatography–tandem mass spectrometry based drug quantification.

    Serial crystallography is an increasingly important approach to protein crystallography that exploits both X-ray free-electron laser (XFEL) and synchrotron radiation. Serial crystallography recovers complete X-ray diffraction data by processing and merging diffraction images from thousands of randomly oriented non-uniform microcrystals, of which all observations are partial Bragg reflections. Random fluctuations in the XFEL pulse energy spectrum, variations in the size and shape of microcrystals, integrating over millions of weak partial observations and instabilities in the XFEL beam position lead to new types of experimental errors. The quality of Bragg intensity estimates deriving from serial crystallography is therefore contingent upon assumptions made while modeling these data. Here it is observed that serial femtosecond crystallography (SFX) Bragg reflections do not follow a unimodal Gaussian distribution and it is recommended that an idealized assumption of single Gaussian peak profiles be relaxed to incorporate apparent asymmetries when processing SFX data. The phenomenon is illustrated by re-analyzing data collected from microcrystals of the Blastochloris viridis photosynthetic reaction center and comparing these intensity observations with conventional synchrotron data. The results show that skewness in the SFX observations captures the essence of the Wilson plot and an empirical treatment is suggested that can help to separate the diffraction Bragg intensity from the background.

  2. Toward Cultural Policy Studies on Mobility: Reflections on a Study of the Hong Kong Working Holiday Scheme

    Directory of Open Access Journals (Sweden)

    Louis Ho

    2017-05-01

    Full Text Available Cultural policy is predominantly, and practically, considered the sum of a government’s activities with respect to the arts, humanities and heritage. Thus, cultural policy encompasses a much broader range of activities than was traditionally associated with an arts policy. Critical cultural policy studies, then, sees a distinction between ‘explicit’ cultural policies that are manifestly labelled as ‘cultural’, and ‘implicit’ cultural policies that are not labelled as such, but that work to shape cultural experiences. This article considers this explicit/implicit cultural policy distinction through John Urry’s idea of ‘social as mobility’, suggesting that some public policies regarding mobility (such as immigration, international trade and labour policy have led to specific cultural consequences and therefore qualify as implicit cultural policy. Using Hong Kong’s working holiday scheme as a case study, this article explores how an economic policy on temporary immigrant labour involves a deliberate cultural agenda as well as ‘unintentional’ cultural consequences and problematises the fact that cultural policy studies are largely framed by the idea of ‘social as society’.

    PurposeThis study was designed to investigate the effects of stenting across the branching arteries on the patency and stent-tissue responses over the branching arterial orifices. Methods: Thirteen dogs were observed after placing aortic stents across the celiac arteries (CA), superior mesenteric arteries (SMA), and renal arteries (RA). The animals were grouped according to stent types: large-cell group (n = 6) and small-cell group (n = 7). Angiography was performed to evaluate the branching artery patency at 2, 6, and 12 months after stent insertion, and the stent-tissue responses covering the orifices were evaluated on histopathologic examination. Results: All branching arteries were patent on follow-up angiography; however, three patterns of stent-tissue responses over the orifices were observed: neointimal layering, bridging septa, and papillary hyperplasia. Although neointimal layering and bridging septa were evenly observed, severe papillary hyperplasia was more frequent at SMA and CA than RA. Four RA showed less than 50% ostial patency, and localized infarct was observed in six kidneys (24%). The ostial patency tended to decrease with small-cell stent during the follow-up period. Conclusions: Various stent-tissue responses over the branching artery orifices are induced by the aortic stent covering the branching arteries and may not be easily detected by conventional angiography. Subclinical renal infarct also may occur despite patent renal angiography.

    Multiple sclerosis (MS) has a variable progression with an early onset of atrophy. Individual longitudinal radiological evaluations (over decades) are difficult to perform due to the limited availability of magnetic resonance imaging (MRI) in the past, patients lost in follow-up, and the continuous updating of scanners. We studied a cohort with widespread disease duration at baseline. The observed individual atrophy rates over time of 10 years represented four decades of disease span. Thirty-seven MS patients (age range 24-65 years with disease duration 1-33 years) were consecutively selected and evaluated with MRI at baseline 1995 and in 1996. They were followed up for a decade (mean of 9.25 years, range 7.3-10 years) up to 2003-2005. Brain parenchymal volume and volumes of the supratentorial ventricles were analyzed with semi-automated volumetric measurements at three time points (1995, 1996, and 2003-2005). Volumetric differences were found over shorter periods of time (1-7 months); however, differences vanished by the end of follow-up. A uniform longitudinal decrease in brain volume and increase in ventricle volumes were found. Frontal horn width (1D) correlated strongest to 3D measures. No statistical differences of atrophy rates between MS courses were found. Supratentorial ventricular volumes were associated with disability and this association persisted during follow-up. Despite variable clinical courses, the degenerative effects of MS progression expressed in brain atrophy seem to uniformly progress over longer periods of time. These volumetric changes can be detected using 1D and 2D measurements performed on a routine PACS workstation. (orig.)

    Full Text Available Abstract Background Mental illnesses are increasingly recognised as a leading cause of disability worldwide, yet many countries lack a mental health policy or have an outdated, inappropriate policy. This paper explores the development of appropriate mental health policies and their effective implementation. It reports comparative findings on the processes for developing and implementing mental health policies in Ghana, South Africa, Uganda and Zambia as part of the Mental Health and Poverty Project. Methods The study countries and respondents were purposively selected to represent different levels of mental health policy and system development to allow comparative analysis of the factors underlying the different forms of mental health policy development and implementation. Data were collected using semi-structured interviews and document analysis. Data analysis was guided by conceptual framework that was developed for this purpose. A framework approach to analysis was used, incorporating themes that emerged from the data and from the conceptual framework. Results Mental health policies in Ghana, South Africa, Uganda and Zambia are weak, in draft form or non-existent. Mental health remained low on the policy agenda due to stigma and a lack of information, as well as low prioritisation by donors, low political priority and grassroots demand. Progress with mental health policy development varied and respondents noted a lack of consultation and insufficient evidence to inform policy development. Furthermore, policies were poorly implemented, due to factors including insufficient dissemination and operationalisation of policies and a lack of resources. Conclusions Mental health policy processes in all four countries were inadequate, leading to either weak or non-existent policies, with an impact on mental health services. Recommendations are provided to strengthen mental health policy processes in these and other African countries.

    Here we examine the potential of serial Broad Ion Beam (BIB) Ar + ion polishing as an advanced serial section tomography (SST) technique for destructive 3D material characterisation for collecting data from volumes with lateral dimensions significantly greater than 100µm and potentially over millimetre sized areas. Further, the associated low level of damage introduced makes BIB milling very well suited to 3D EBSD acquisition with very high indexing rates. Block face serial sectioning data registration schemes usually assume that the data comprises a series of parallel, planar slices. We quantify the variations in slice thickness and parallelity which can arise when using BIB systems comparing Gatan PECS and Ilion BIB systems for large volume serial sectioning and 3D-EBSD data acquisition. As a test case we obtain 3D morphologies and grain orientations for both phases of a WC-11%wt. Co hardmetal. In our case we have carried out the data acquisition through the manual transfer of the sample between SEM and BIB which is a very slow process (1-2 slice per day), however forthcoming automated procedures will markedly speed up the process. We show that irrespective of the sectioning method raw large area 2D-EBSD maps are affected by distortions and artefacts which affect 3D-EBSD such that quantitative analyses and visualisation can give misleading and erroneous results. Addressing and correcting these issues will offer real benefits when large area (millimetre sized) automated serial section BIBS is developed. Copyright © 2016. Published by Elsevier B.V.

    2017-05-01

    During the course of divergent thinking (DT), the number of generated ideas decreases while the originality of ideas increases. This phenomenon is labeled as serial order effect in DT. The present study investigated whether different executive processes (i.e., updating, shifting, and inhibition) specifically contribute to the serial order effect in DT. Participants' executive functions were measured by corresponding experimental tasks outside of the EEG lab. They were required to generate original uses of conventional objects (alternative uses task) during EEG recording. The behavioral results revealed that the originality of ideas was higher in later stage of DT (i.e., Epoch 2) than in its earlier stage (i.e., Epoch 1) for higher-shifting individuals, but showed no difference between two epochs for lower-shifting individuals. The EEG results revealed that lower-inhibition individuals showed stronger upper alpha (10-13Hz) synchronization in left frontal areas during Epoch 1 compared to during Epoch 2. For higher-inhibition individuals, no changes in upper alpha activity from Epoch 1 to Epoch 2 were found. These findings indicated that shifting and inhibition contributed to create a serial order effect in DT, perhaps because individuals suppress interference from obvious ideas and switch to new idea categories during DT, thus more original ideas appear as time passes by.

    Nutrition sensitive policy addresses the underlying determinants of nutrition-related disease and is a powerful tool in reducing the incidence of non-communicable disease. Some members of the food industry have long standing commitments to health-oriented nutrition policies. The aim of this study was to develop and apply a balanced scorecard of nutrition sensitive indicators to the policies of influential New Zealand food and beverage manufacturers and explore factors affecting policy processes. Results: The average nutrition sensitivity score of the twenty influential manufacturers policies was 42 against a benchmark of 75. Some manufacturers performed well whilst others had substantial scope for improvement, the largest variation was in policy development and implementation, whereas nutrition quality was relatively consistent. Manufacturers with written policy (n = 11) scored on average three times higher than their counterparts with verbal policy. The value a manufacturer placed on nutrition influenced whether formal nutrition policies were developed. The reputational risk of failing to deliver on publicly declared nutrition commitments acted as an informal accountability mechanism. We conclude the balanced scorecard offers a useful tool for assessing the nutrition sensitivity of influential food and beverage manufacturers’ policies. Our results provide a baseline for repeat assessments of the nutrition sensitivity of food manufacturers’ policies. PMID:29257049

Our results provide a baseline for repeat assessments of the nutrition sensitivity of food manufacturers’ policies.

  11. Serial-omics characterization of equine urine.

    Full Text Available Horse urine is easily collected and contains molecules readily measurable using mass spectrometry that can be used as biomarkers representative of health, disease or drug tampering. This study aimed at analyzing microliter levels of horse urine to purify, identify and quantify proteins, polar metabolites and non-polar lipids. Urine from a healthy 12 year old quarter horse mare on a diet of grass hay and vitamin/mineral supplements with limited pasture access was collected for serial-omics characterization. The urine was treated with methyl tert-butyl ether (MTBE and methanol to partition into three distinct layers for protein, non-polar lipid and polar metabolite content from a single liquid-liquid extraction and was repeated two times. Each layer was analyzed by high performance liquid chromatography-high resolution tandem mass spectrometry (LC-MS/MS to obtain protein sequence and relative protein levels as well as identify and quantify small polar metabolites and lipids. The results show 46 urine proteins, many related to normal kidney function, structural and circulatory proteins as well as 474 small polar metabolites but only 10 lipid molecules. Metabolites were mostly related to urea cycle and ammonia recycling as well as amino acid related pathways, plant diet specific molecules, etc. The few lipids represented triglycerides and phospholipids. These data show a complete mass spectrometry based-omics characterization of equine urine from a single 333 μL mid-stream urine aliquot. These omics data help serve as a baseline for healthy mare urine composition and the analyses can be used to monitor disease progression, health status, monitor drug use, etc.

  12. Serial rotatostereography - A new diagnostic method

    In the previous study using cine, a cine film stereoprojector showed the adjacent two frames of cine film simultaneously, such as frames 1 and 2, 2 and 3, 3 and 4, and so on, consecutively. Because some intracranial lesions require emergency surgery immediately after angiography, a real time display method of serial rotatostereography was necessary. In order to show the consecutive adjacent two frames of a video disc simultaneously, using the same method as with the cine stereoprojector, a video disc recorder (VDR) (VM-1000M) and two video memories (Image Σ) were required. This VDR has the ability of advancing, stopping, and reversing the display of memories. A control unit was manufactured in order to display these memories advancing and reversing continuously. As a result of this continuous semirotation stereo display, the anteroposterior projection was reversed, showing the posteroanterior view during ''reversing mode''. Thus a lead relay circuit was manufactured to prevent this phenomenon. Recording was done using a memory disc recorder (FOM 2200F), which has the ability of recording 10,000 frames per disc. Each frame can also be recorded on imaging film using O · X Multi Camera 400X. Finally, stereoscopic views of cerebral circulation, using a single injection of contrast media and rapid rotation of the gantry, were obtained using two cathode-ray tubes (CRTs) and a stereoviewer (Continuous Semi-rotation Classical Stereo Display Method). Stereoscopic views were also obtained using a single CRT, which displayed the images in a semirotating fashion similar to a oscillating fan head (Continuous Semi-rotation New Stereo Display Method).

    Cement-retained implant-supported prostheses are particularly indicated where access for screw placement is limited or impossible like in posterior locations or where there is limited jaw opening. The patient in this case report suffered from limited jaw opening as a result of a long history of temporomandibular joint ankylosis related to hemophilia. Cement-retained implant-supported prostheses coupled with serial extraction, serial implant installations, and chairside provisional restorations made uneventful treatment possible.

    The U-shaped serial position curve (SPC) of single-trial free recall is a well-established empirical fact, and there is ample evidence that it is the result of two different memory functions. However, it is insufficiently clear whether the same holds true for the SPC of multi-trial free recall. Free

    Science.gov (United States)

    Wang, Y

    1995-01-01

    During the Chinese dynasties of Sui and Tang, neighboring minority groups were forced to migrate to less settled areas of China. During the Song dynasty (960-1279) the Han government lost control of neighboring ethnic groups. Ethnically dominated states on their own expanded to the hinterlands, formed the national governments of Yuan and Qing, and established the local power of Liao and Jin in Han-dominated areas. During the Han dynasty the movement of minorities fulfilled the purpose of helping cultivate undeveloped land. The Han governments of feudal China held compulsory migration policies and policies encouraging minorities to move to less inhabited places. Han governments prior to the Tang and Song dynasties held policies favorable to minority settlements. During the Tang dynasty land was given to minority settlers. During the Song dynasty the Han government held a policy which prohibited taxation and harassment of new minority settlers. Minorities gained improved living conditions and the government achieved pacification. Resettlement of minorities either from forced or voluntary migration facilitated communication with the Han and promoted the exchange of culture, but also intensified ethnic conflict. The reason for the ethnic conflict was a question of control. Ethnic governments encouraged in-migration and adopted policies of compulsory and voluntary migration. Ethnic minorities in the north and west practiced mainly compulsory migration. Ethnic conflict in the Qin and Han dynasties occurred between the Han and the Huns. During the Eastern Jin and Northern dynasties minority governments captured Han and other ethnic groups. The rule of minority government was strengthened by voluntary migration. The frequent power shifts in ancient China contributed to the blending of Chinese nationalities.

  2. Effect of Different Attentional Instructions on the Acquisition of a Serial Movement Task

    2014-12-01

    Full Text Available Recent research in attentional focus of instruction has predominantly over-emphasized the investigation of discrete and continuous skills rather than serial skills. The purpose of this study was therefore to examine the effect of different attentional focus instructions on learning a serial skill task (i.e., taekwondo routine in novice learners. It was predicted that the use of movement outcome instructions could enhance the learning of a serial skill as previously supported in studies examining the acquisition of discrete and continuous skills. Thirteen female participants were recruited for this study and were assigned to either movement form condition - control group (n = 7 or movement outcome condition – treatment group (n = 6. All participants underwent 12 practice sessions over an 8-week period with their respective instructional conditions with each session lasting 30 minutes. Video recording of the serial skill tasks (hand techniques, kicking techniques and 10-step routine were captured at “the-twelfth-training session”, “after 1-week”, and “after 1-month”. It was found that more participants in the treatment group obtained a higher score in all three serial skill tasks, especially in Mastery component of ‘Kicking’ techniques at ‘after 1-week’ (p < 0.05, r = 0.57. This study suggested that movement outcome instructions have positive medium effect on balance control for serial skill task, especially in kicking actions.

  4. Reaction kinetics in open reactors and serial transfers between closed reactors

    Blokhuis, Alex; Lacoste, David; Gaspard, Pierre

    2018-04-01

    Kinetic theory and thermodynamics of reaction networks are extended to the out-of-equilibrium dynamics of continuous-flow stirred tank reactors (CSTR) and serial transfers. On the basis of their stoichiometry matrix, the conservation laws and the cycles of the network are determined for both dynamics. It is shown that the CSTR and serial transfer dynamics are equivalent in the limit where the time interval between the transfers tends to zero proportionally to the ratio of the fractions of fresh to transferred solutions. These results are illustrated with a finite cross-catalytic reaction network and an infinite reaction network describing mass exchange between polymers. Serial transfer dynamics is typically used in molecular evolution experiments in the context of research on the origins of life. The present study is shedding a new light on the role played by serial transfer parameters in these experiments.

    Implementing national policies may threaten the eligibility of renewable energy projects for Clean Development Mechanism/Joint Implementation (CDM/JI), thus reducing international development financing. Countries hence need to be very careful when crafting their national promotion policies. The objectives of the Renewable Energy Technology Deployment (IEA-RETD) project were to perform a scoping study on the interplay between national Renewable Energy (RE) promotion policies and international carbon trade. The study summarizes the ongoing discussion, describes the main barriers that may hinder -- or at least not sufficiently support -- the implementation of national RE promotion policies, and provides suggestions for removing these barriers.

    While there has been interest in promoting the use of renewable energy in electricity production for a number of years in the United States, the market share of non-hydro renewable energy sources in electricity production has remained at about 2 percent over the past decade. The paper reviews the principal energy resources used for electricity production, considers the changing regulatory environment for the electricity industry, and describes government policies that have been used to promote green electricity in the United States, with an emphasis on measures adopted by state governments. Factors influencing the development of green power markets are also discussed, including underlying economic issues, public policy measures, the regulatory environment, external costs, and subsidies. Without significant increases in fossil fuel prices, much more stringent environmental regulations, or significant changes in electricity customer preferences, green electricity markets are likely to develop slowly in the United States

    Interoperability of potentially heterogeneous databases has been an ongoing research issue for a number of years in the database community. With the trend towards globalization of data location and data access and the consequent requirement for the coexistence of new data stores with legacy systems, the cooperation and data interchange between data repositories has become increasingly important. The emergence of the eXtensible Markup Language (XML) as a database independent representation for data offers a suitable mechanism for transporting data between repositories. This paper describes a research activity within a group at CERN (called CMS) towards identifying and implementing database serialization and deserialization methods that can be used to replicate or migrate objects across the network between CERN and worldwide centres using XML to serialize the contents of multiple objects resident in object-oriented databases.

  1. Output order in immediate serial recall.

    Tan, Lydia; Ward, Geoff

    2007-07-01

    In two experiments, we examined the effect of output order in immediate serial recall (ISR). In Experiment 1, three groups of participants saw lists of eight words and wrote down the words in the rows corresponding to their serial positions in an eight-row response grid. One group was precued to respond in forward order, a second group was precued to respond in any order, and a third group was postcued for response order. There were significant effects of output order, but not of cue type. Relative to the forward output order, the free output order led to enhanced recency and diminished primacy, with superior performance for words output early in recall. These results were replicated in Experiment 2 using six-item lists, which further suggests that output order plays an important role in the primacy effect in ISR and that the recency items are most highly accessible at recall.

    We performed serial single-photon emission CT (SPECT) with N-isopropyl-p-({sup 123}I)-Iodoamphetamine to measure the regional cerebral blood flow (rCBF) in 15 children with partial epilepsy. SPECT showed focal changes in 14 cases. Ten cases had abnormalities in the initial SPECT and another four cases in the second test. The cases with normal rCBF in initial SPECT had been tested in an early phase after the onset, and then decreased rCBF were observed in the second SPECT. The cases with both abnormal rCBF in the initial SPECT and improved rCBF in the second SPECT showed good prognosis in clinico-electrophysiological evolutions. In cases with abnormal changes of rCBF in the second SPECT, clinical prognosis was found to be not so good. These findings suggest that serial SPECT may be used to follow the course of epilepsy.

    A complex, poorly understood bifurcated health policy regime exists for Canada's First Nations people for extended health benefits coverage. This research adds to a small body of literature on the regime's impact on access and quality of care and its role in perpetuating health inequities in First Nations populations. Using a case study of sleep apnea care in Saskatchewan, we identified issues of health service access and coverage through a literature review of extended benefits programs, legislation and policies and through 10 key informant interviews with federal and provincial extended benefit program administrators and sleep medicine physicians. Important access and coverage differences were found for First Nations populations, many of which were recognized by federal and provincial policy makers. Despite these, government respondents recommended few policy ameliorations, perhaps due to system complexities, constitutional constraints or political sensitivities. We suggest three policy options to ameliorate current hardships wrought by this policy bifurcation. Copyright © 2017 Longwoods Publishing.

    Full Text Available Cluster policies have attracted increasing attention worldwide, but only a few studies have focused on their management by local cluster organizations. We investigate the relationship between national cluster policies and their management by local cluster organizations from a comparative perspective. For this purpose, we provide a detailed comparison of national cluster policies in Japan, Germany, and France as well as six prominent biotechnology clusters in these countries. Information on the focal clusters and on the management of cluster policies was obtained using semi-structured interviews with cluster managers. We find that national cluster policies considerably differ among these countries according to basic conditions of clusters and that the patterns of national cluster policy are closely related to those of local cluster management, despite some differences between clusters in the same country caused by various regional characteristics.

    The guppy is a tropical fish that has been used as an experimental model organism in science. It is a species well adapted to the natural environment and that can support adverse environmental conditions, and so, at occasions, its presence can be indicative of environmental disturbances. Moreover, as the liver is very important when studying fish diseases, the knowledge of normal microanatomy is essential to assess histological changes, e.g., related to environmental change or toxic pollutants. The target organ of this histological study is the liver. The main objective is to contribute to the identification of anatomical and structural variations of this organ in different teleost species. We studied the distribution and spatial organization of the different types of blood vessels and biliary ducts and the relationships between them are established. For this, each liver was totally sectioned and the serial sections inspected in detail. The guppy liver presented intra-hepatic pancreatic tissue and so reported its association with the vascular and biliary elements. We observed that the input of afferent vessels (i.e., bringing blood into the liver) occur not only in the hilum but pierce and enter the organ at various points. Within the liver, venous vessels and bile ducts are seen, isolated or associated as venous-arteriolar tracts (VAT), and venous-biliary- arteriolar tracts (VBAT). Sometimes, pancreocytes appear within the liver surrounding isolated veins, forming venous tract with pancreatic acini (VT-P), or dual associations with afferent vessels, forming venous-arteriolar tracts with pancreatic acini (VAT-P). Intrahepatic pancreatic ducts were tiny and rare, putting in question the functional role of the acini. Contrary to other fish species, we did not spot isolated arterioles and associations between these and biliary ducts (BAT).We found aggregates of macrophages, namely associated with afferent and efferent (i.e., draining blood out) venous vessels; the

    Metastatic colorectal cancer (mCRC) may present various behaviours that define different courses of tumor evolution. There is presently no available tool designed to assess tumor aggressiveness, despite the fact that this is considered to have a major impact on patient outcome. CORIOLAN is a single-arm prospective interventional non-therapeutic study aiming mainly to assess the natural tumor metabolic progression index (TMPI) measured by serial FDG PET-CT without any intercurrent antitumor therapy as a prognostic factor for overall survival (OS) in patients with mCRC. Secondary objectives of the study aim to test the TMPI as a prognostic marker for progression-free survival (PFS), to assess the prognostic value of baseline tumor FDG uptake on PFS and OS, to compare TMPI to classical clinico-biological assessment of prognosis, and to test the prognostic value on OS and PFS of MRI-based apparent diffusion coefficient (ADC) and variation of vADC using voxel-based diffusion maps. Additionally, this study intends to identify genomic and epigenetic factors that correlate with progression of tumors and the OS of patients with mCRC. Consequently, this analysis will provide information about the signaling pathways that determine the natural and therapy-free course of the disease. Finally, it would be of great interest to investigate whether in a population of patients with mCRC, for which at present no known effective therapy is available, tumor aggressiveness is related to elevated levels of circulating tumor cells (CTCs) and to patient outcome. Tumor aggressiveness is one of the major determinants of patient outcome in advanced disease. Despite its importance, supported by findings reported in the literature of extreme outcomes for patients with mCRC treated with chemotherapy, no objective tool allows clinicians to base treatment decisions on this factor. The CORIOLAN study will characterize TMPI using FDG-PET-based metabolic imaging of patients with chemorefractory m

    Full Text Available The large number of regional trade agreements notified to the World Trade Organization (WTO significantly influenced the flow of world trade. By April 2014 there had been notified 583 regional trade agreements to the WTO, of which only 379 are in force. The objective of this paper is to highlight the importance of regional trade agreements in world trade, especially the importance of establishing a regional competition policy in these agreements. The research methodology used is the analysis of legislation governing preferential trade agreements at the level of WTO, the collection and interpretation of statistical data provided by the WTO Secretariat, the case study, namely the study of literature. The paper is structured in three parts. The first part of the paper examines the basic laws based on which regional trade agreements are notified to the WTO and the evolution of these agreements in the period 1958-2013. The second part of the paper is devoted to the analysis of competition policy in regional trade agreements. In this part of the paper, to highlight the patterns of competition policy adopted under these agreements was analyzed by three case studies of competition policy in the EU, ASEAN and NAFTA. The three case studies have revealed that the three preferential trade agreements present regional competition policies with varying degrees of integration. The most complex form of competition policy is found in the European Union, because we are talking about a centralized model of competition policy. ASEAN presents a partially decentralized model, while NAFTA scrolls with a decentralized model of competition policy. The last part of the paper presents the characteristics of the four models of competition policy identified in the preferential trade agreements in force. It should be emphasized that if the initial preferential trade agreements have not put a great emphasis on the rules of competition policy, practice has shown the importance

    Full Text Available This article approaches the historical development of the field of migratory studies in Argentina and makes a review of the academic production around the so - called "migratory policies." The systematization of these studies, historically placed on migration policies, aims to highlight some of the most significant contributions of the research during the last 30 years, to understand or explain various aspects and dimensions of the Argentinean migration policy. To achieve this, texts were selected that derived from empirical research that explicitly assume the migratory policies as the object of study, or whose themes and research problems adopt as a framework for discussion the policies and practices aimed at regulating migration and mobility in Argentina. The organization and presentation of these selected texts consider issues related to the interests and thematic concerns, disciplinary and analytical approaches, distinct periods, scales of analysis and sources of information.

    In the current world of applications that use reconfigurable technology implemented on field programmable gate arrays (FPGAs), there is a need for flexible architectures that can grow as the systems evolve. A project has limited resources and a fixed set of requirements that development efforts are tasked to meet. Designers must develop robust solutions that practically meet the current customer demands and also have the ability to grow for future performance. This paper describes the development of a high speed serial data streaming algorithm that allows for transmission of multiple data channels over a single serial link. The technique has the ability to change to meet new applications developed for future design considerations. This approach uses the Xilinx Serial RapidIO LOGICORE Solution to implement a flexible infrastructure to meet the current project requirements with the ability to adapt future system designs.

    of Capability-Expectations Gap in the study of European foreign policy. Through examples from the literature, it is shown that the concept sets up standards for the EU as a foreign policy actor that are not met by most other international actors and that this curtails analysis of EU foreign policy......This book argues that theories of European foreign policy are performative: they create the objects they analyse.The book first outlines the performativity approach to the role of theories based on the work of Derrida. It then examines the performative role of Christopher Hill's concept....... It then demonstrates that the widespread use of the concept of ‘gap’ in different forms affects the way in which EU foreign policy has been studied and that it always produces the same result: the EU is an unfulfilled actor outside the realm of “normal” actors in IR....

    Full Text Available This article aims to present the results of a comparative study of national educative policies for integration of information and communication technologies (ICT used in basic education schools in Brazil and Spain. In general terms, this article intends to examine possible convergences and divergences in objectives presented by these policies. The time frame was between 1997 and 2010, when these policies and the launch of new transnational policies for ICT integration began. The research has a qualitative approach and a descriptive and documentary procedure, through the comparative study method. The sources were laws, resolutions, regulations, decrees, regulatory guidelines, official informs, official communications and technical reports. So, on the whole, we ascertained that these policies seek an educational quality, aligned by the market logic, with constitutive elements of the recommendations of international organisations, and they are directed to the technological development and economic growth, thus legitimizing the hegemonic discourse of globalization.

    The evidence evaluating the association between school obestiy prevention policies and student weight is mixed. The lack of consistent findings may result, in part, from limited evaluation approaches. The goal of this article is to demonstrate the use of surveillance data to address methodological gaps and opportunities in the school policy evaluation literature using lessons from the School Obesity-Related Policy Evaluation (ScOPE) study. The ScOPE study uses a repeated, cross-sectional study design to evaluate the association between school food and activity policies in Minnesota and behavioral and weight status of youth attending those schools. Three surveillance tools are used to accomplish study goals: Minnesota School Health Profiles (2002-2012), Minnesota Student Survey (2001-2013), and National Center for Educational Statistics. The ScOPE study takes two broad steps. First, we assemble policy data across multiple years and monitor changes over time in school characteristics and the survey instrument(s), establish external validity, and describe trends and patterns in the distribution of policies. Second, we link policy data to student data on health behaviors and weight status, assess nonresponse bias, and identify cohorts of schools. To illustrate the potential for program evaluators, the process, challenges encountered, and solutions used in the ScOPE study are presented. © 2014 Society for Public Health Education.

    2013-06-01

    Full Text Available Being aware of the role of electoral systems as the most important mechanisms of fostering political interaction in a political system of a certain democratic society, it is our intention to study and theoretically and practically analyze the establishment and functioning of the electoral system in Kosovo, in the temporal context of the last decade. Before that thought, several standard theoretical modalities attributable to electoral systems are to be set, with a view of explaining the role and functions of the electoral systems in consolidating basic attributes of a mature democracy. In our case studies, amongst the most important attributes under analysis are: elections, as an instrument of civil participation in public policies. Furthermore, in studying the function of elections, we shall make efforts to elaborate on the level of political culture in Kosovo, creation of authority and legitimacy, and the extent of maturity of Kosovar society itself. Since Kosovo has been under international administration for more than ten years, the analysis of the electoral system in Kosovo is found to be sui generis, and this fact allows for an extraordinary understanding of the role of elections as an instrument of citizens for participating in public policies and public life in Kosovo. In attaining such goals, we shall focus on the analysis of all cycles of elections held in Kosovo since 2001, and up to the constitutional reforms ongoing related to electoral reforms in Kosovo.

  9. How do researchers influence decision-makers? Case studies of Mexican policies.

    Though the problems translating or applying research in policy-making are legion, solutions are rare. As developing countries increase their capacities to develop effective local solutions to their health problems, they confront the research/policy dilemma. Yet few descriptive studies of research-policy links can be found from developing countries, and the relevance of European and North American models and data is questionable. We report the results of a descriptive study from Mexico of the relationship between health research and policy in four vertical programmes (AIDS, cholera, family planning, immunization). We interviewed 67 researchers and policy-makers from different institutions and levels of responsibility. We analyzed interviewee responses looking for factors that promoted or impeded exchanges between researchers and policy-makers. These were, in turn, divided into emphases on content, actors, process, and context. Many of the promoting factors resembled findings from studies in industrialized countries. Some important differences across the four programmes, which also distinguish them from industrialized country programmes, included extent of reliance on formal communication channels, role of the mass media in building social consensus or creating discord, levels of social consensus, role of foreign donors, and extent of support for biomedical versus social research. We recommend various ways to increase the impact of research on health policy-making in Mexico. Some of the largest challenges include the fact that researchers are but one of many interest groups, and research but one input among many equally legitimate elements to be considered by policy-makers. Another important challenge in Mexico is the relatively small role played by the public in policy-making. Further democratic changes in Mexico may be the most important incentive to increase the use of research in policy-making.

    Aims Local alcohol policies can be effective in reducing alcohol-related harm. The aim of this study was to examine local government responses to alcohol-related problems and identify factors influencing their development and adoption of alcohol policy. Designsettings and participants Case studies were used to examine local government responses to alcohol problems in three New Zealand communities: a rural town, a provincial city and a metropolitan city. Newspaper reports, local government documents and key informant interviews were used to collect data which were analysed using two conceptual frameworks: Kingdon's Streams model and the Stakeholder model of policy development. Measurements Key informant narratives were categorized according to the concepts of the Streams and Stakeholder models. Findings Kingdon's theoretical concepts associated with increased likelihood of policy change seemed to apply in the rural and metropolitan communities. The political environment in the provincial city, however, was not favourable to the adoption of alcohol restrictions. The Stakeholder model highlighted differences between the communities in terms of power over agenda-setting and conflict between politicians and bureaucrats over policy solutions to alcohol-related harm. These differences were reflected in the ratio of policies considered versus adopted in each location. Decisions on local alcohol policies lie ultimately with local politicians, although the policies that can be adopted by local government are restricted by central government legislation. Conclusions The adoption of policies and strategies to reduce alcohol-related harm may be better facilitated by an agenda-setting process where no ‘gate-keepers’ determine what is included into the agenda, and community mobilization efforts to create competitive local government elections around alcohol issues. Policy adoption would also be facilitated by more enabling central government legislation. PMID:23130762

    2006-01-01

    The purpose behind building the industrial energy demand model was to enable assessment of the impact of potential policy options and to forecast future energy demand under various assumptions, including the impact of the possible removal of energy subsidies in accordance with the World Trade Organization (WTO) agreement. The results of the model, based on three scenarios, underline several important issues: With nominal energy prices staying the same (the status quo) and with inflation and economic growth continuing to expand (i.e. baseline scenario), it is expected that industrial demand will grow. In this sector, energy consumption is projected to grow at an annual growth rate of about 3.5 per cent throughout the forecast period. In the moderate scenario, however, this drops to 1.9 per cent and when all energy subsidies are removed as in the case of the extreme scenario, the energy consumption is projected to grow by only 1.5 per cent annually throughout the same period. Moreover, with regards to inter-fuel substitution, the model forecast indicates that electricity and natural gas consumption will decline, while the consumption of oil products will increase in all scenarios. The results of the model also indicate that the changing price structure of energy resources should be done in a comprehensive manner. In other words, electricity prices should be adjusted upwards instantly with the adjustment of oil products' prices and natural gas otherwise, a massive inter-fuel substitution will occur within the various consuming industries.

  19. Breaking the indexing ambiguity in serial crystallography.

    Science.gov (United States)

    Brehm, Wolfgang; Diederichs, Kay

    2014-01-01

    In serial crystallography, a very incomplete partial data set is obtained from each diffraction experiment (a `snapshot'). In some space groups, an indexing ambiguity exists which requires that the indexing mode of each snapshot needs to be established with respect to a reference data set. In the absence of such re-indexing information, crystallographers have thus far resorted to a straight merging of all snapshots, yielding a perfectly twinned data set of higher symmetry which is poorly suited for structure solution and refinement. Here, two algorithms have been designed for assembling complete data sets by clustering those snapshots that are indexed in the same way, and they have been tested using 15,445 snapshots from photosystem I [Chapman et al. (2011), Nature (London), 470, 73-77] and with noisy model data. The results of the clustering are unambiguous and enabled the construction of complete data sets in the correct space group P63 instead of (twinned) P6322 that researchers have been forced to use previously in such cases of indexing ambiguity. The algorithms thus extend the applicability and reach of serial crystallography.

    This paper describes a set of tools allowing experimentalists insight into the variation present within large serial data sets. Ultrafast diffraction at X-ray free-electron lasers (XFELs) has the potential to yield new insights into important biological systems that produce radiation-sensitive crystals. An unavoidable feature of the ‘diffraction before destruction’ nature of these experiments is that images are obtained from many distinct crystals and/or different regions of the same crystal. Combined with other sources of XFEL shot-to-shot variation, this introduces significant heterogeneity into the diffraction data, complicating processing and interpretation. To enable researchers to get the most from their collected data, a toolkit is presented that provides insights into the quality of, and the variation present in, serial crystallography data sets. These tools operate on the unmerged, partial intensity integration results from many individual crystals, and can be used on two levels: firstly to guide the experimental strategy during data collection, and secondly to help users make informed choices during data processing.

    This study aims to see the impact and benefits as an outcome of a policy, where this policy is in the form of spatial planning (Regional Planning). As known RTRW is a product that can be regarded as "the book of development" in every region both in the provincial and regional levels. One of them is as a decision tool for investors (investors) in increasing local development investment, spatial planning (RTRW) is also expected to maintain the environment, in order to support the sustainability of regional development. In reality, there are still many conflicts of interest in the implementation process of regional development, especially between economic and environmental interests. Often the interests of regional sustainability are placed at a lower level (less priority) than investment / economy. Land conversion that is inconsistent with district / city spatial planning RTRW is relatively still occurring, especially for economic purposes. Lack of policy called spatial plan in this case RTRW Province and Regency in responding to existing condition in field. How can a product that is said to be "Scripture" a regional planning is powerless in fulfilling the space for investment in the form of industry, commercial, housing and so forth. There are several results that can be concluded in this study. Basically, the importance of the environment at least can be used as the basis or priority of the main decision makers above economic interests and other politic interests. The current Spatial Plan / RTRW document still holds a big question whether at the time of compilation it follows the norms and rules in a plan (data accuracy, through input process from the community).

    Climate change is expected to affect the health of most populations in the coming decades, having the greatest impact on the poorest and most disadvantaged people in the world. The Pacific islands, including Fiji, are particularly vulnerable to the effects of climate change. The three major health impacts of climate change in Fiji explored in this study were dengue fever, diarrhoeal disease, and malnutrition, as they each pose a significant threat to human health. The aim of this study was to investigate to what extent the Fiji National Climate Change Policy, and a selection of relevant sectoral policies, account for these human health effects of climate change. The study employed a three-pronged policy analysis to evaluate: 1) the content of the Fijian National Climate Change Policy and to what extent health was incorporated within this; 2) the context within which the policy was developed; 3) the relevant processes; and 4) the actors involved. A selection of relevant sectoral policies were also analysed to assess the extent to which these included climate change and health considerations. The policy analysis showed that these three health impacts of climate change were only considered to a minor extent, and often indirectly, in both the Fiji National Climate Change Policy and the corresponding National Climate Change Adaptation Strategy, as well as the Public Health Act. Furthermore, supporting documents in relevant sectors including water and agriculture made no mention of climate change and health impacts. The projected health impacts of climate change should be considered as part of reviewing the Fiji National Climate Change Policy and National Climate Change Adaptation Strategy, and the Public Health Act. In the interest of public health, this should include strategies for combating dengue fever, malnutrition, and water-borne disease. Related sectoral policies in water and agriculture should also be revised to consider climate change and its impact on human

    Full Text Available This study traces the transnational interactions that contributed to introducing the low-carbon economy agenda into Chinese policymaking. A microprocessual two-level analysis (outside-in as well as inside-access is employed to analyse transnational and domestic exchanges. The study provides evidence that low-carbon agenda-setting – introduced by transnational actors, backed by foreign funding, promoted by policy entrepreneurs from domestic research institutes, propelled by top-level attention, but only gradually and cautiously adopted by the government bureaucracy – can be considered a case of effective transnational diffusion based on converging perceptions of novel policy challenges and options. Opinion leaders and policy-brokers from the government-linked scientific community functioned as effective access points to the Chinese government’s policy agenda.

    This paper examines the impact of public policy measures on renewable energy (RE) investments in electricity-generating capacity made by institutional investors. Using a novel combination of datasets and a longitudinal research design, we investigate the influence of different policy measures in a sample of OECD countries to suggest an effective policy mix which could tackle failures in the market for clean energy. The results call for technology-specific policies which take into account actual market conditions and technology maturity. To improve the conditions for institutional investments, advisable policy instruments include economic and fiscal incentives such as feed-in tariffs (FIT), especially for less mature technologies. Additionally, market-based instruments such as greenhouse gas (GHG) emission trading systems for mature technologies should be included. These policy measures directly impact the risk and return structure of RE projects. Supplementing these with regulatory measures such as codes and standards (e.g. RPS) and long-term strategic planning could further strengthen the context for RE investments. - Highlights: • Panel data study on the effectiveness of policies to induce RE investments. • Novel combination of datasets (BNEF/IEA) in solar, wind and biomass sectors. • FIT proves to be more effective than subsidies for less mature technologies. • RPS and tradable permit systems seem more effective for mature technologies. • A long-term strategic planning framework is useful to attract institutional investors

    The development of serial crystallography has been driven by the sample requirements imposed by X-ray free-electron lasers. Serial techniques are now being exploited at synchrotrons. Using a fixed-target approach to high-throughput serial sampling, it is demonstrated that high-quality data can be collected from myoglobin crystals, allowing room-temperature, low-dose structure determination. The combination of fixed-target arrays and a fast, accurate translation system allows high-throughput serial data collection at high hit rates and with low sample consumption.

    Multiple sclerosis (MS) is a serious disease typically occurring in the brain whose diagnosis and efficacy of treatment monitoring are vital. Magnetic resonance imaging (MRI) is frequently used in serial brain imaging due to the rich and detailed information provided. Time-series analysis of images is widely used for MS diagnosis and patient follow-up. However, conventional manual methods are time-consuming, subjective, and error-prone. Thus, the development of automated techniques for the detection and quantification of MS lesions is a major challenge. This paper presents an up-to-date review of the approaches which deal with the time-series analysis of brain MRI for detecting active MS lesions and quantifying lesion load change. We provide a comprehensive reference source for researchers in which several approaches to change detection and quantification of MS lesions are investigated and classified. We also analyze the results provided by the approaches, discuss open problems, and point out possible future trends. Lesion detection approaches are required for the detection of static lesions and for diagnostic purposes, while either quantification of detected lesions or change detection algorithms are needed to follow up MS patients. However, there is not yet a single approach that can emerge as a standard for the clinical practice, automatically providing an accurate MS lesion evolution quantification. Future trends will focus on combining the lesion detection in single studies with the analysis of the change detection in serial MRI. (orig.)

  10. Serial Contradictions. The Italian Debate on Tv Series

    Full Text Available In the last decade the academic debate on television seriality has become lively and often quite animated, in the US as well as in Italy. The traditional hierarchic relation between cinema and television is clearly represented by the form of the most recent tv drama, whose boundaries are more and more difficult to locate. The main questions at stake seem to be the so-called “cinematic television” (Mills, 2013; Jaramillo, 2013, the umbrella definition of “quality tv” (McCabe and Akass, 2007 and its relation with the broadest concept of “complex tv” (Mittell, 2009, 2015. The essay will take into consideration these oxymorons, which are deeply rooted in the Italian tv series debate, with the aim of considering both their risks and their opportunities. A great variety of texts are grouped under the “tv series” label, but they are very different as far as content, production values and audience reactions are concerned. The academic discourse, however, only recently has tried to identify the differences between longstanding mainstream shows (such as, for instance, Grey’s Anatomy or CSI and some more recent, and supposedly “cinematic” series like True Detective or Fargo. Together with the analysis of the oxymoric nature of recent television seriality, the essay will explore the need to historicising what is proving to be one of the most dense and fruitful domains of recent television studies.

    Increasing incidence has led to the re-appearance of pertussis as a public health problem in developed countries. Pertussis infection is usually mild in vaccinated children and adults, but it can be fatal in infants who are too young for effective vaccination (≤3 months). Tailoring of control strategies to prevent infection of the infant hinges on the availability of estimates of key epidemiological quantities. Here we estimate the serial interval of pertussis, i.e., the time between symptoms onset in a case and its infector, using data from a household-based study carried out in the Netherlands in 2007-2009. We use statistical methodology to tie infected persons to probable infector persons, and obtain statistically supported stratifications of the data by person-type (infant, mother, father, sibling). The analyses show that the mean serial interval is 20 days (95% CI: 16-23 days) when the mother is the infector of the infant, and 28 days (95% CI: 23-33 days) when the infector is the father or a sibling. These time frames offer opportunities for early mitigation of the consequences of infection of an infant once a case has been detected in a household. If preventive measures such as social distancing or antimicrobial treatment are taken promptly they could decrease the probability of infection of the infant. Copyright © 2014 The Authors.

    The thousands of serial images used for medical pedagogy cannot be included in a printed book; they also cannot be efficiently handled by ordinary image viewer software. The purpose of this study was to provide browsing software to grasp serial medical images efficiently. The primary function of the newly programmed software was to select images using 3 types of interfaces: buttons or a horizontal scroll bar, a vertical scroll bar, and a checkbox. The secondary function was to show the names of the structures that had been outlined on the images. To confirm the functions of the software, 3 different types of image data of cadavers (sectioned and outlined images, volume models of the stomach, and photos of the dissected knees) were inputted. The browsing software was downloadable for free from the homepage (anatomy.co.kr) and available off-line. The data sets provided could be replaced by any developers for their educational achievements. We anticipate that the software will contribute to medical education by allowing users to browse a variety of images. © 2017 The Korean Academy of Medical Sciences.

  13. SERIAL EFFECTS OF EVIDENCE ON LEGAL DECISION-MAKING

    Raluca Enescu

    2012-07-01

    Full Text Available The order in which evidence is presented to a criminal court might influence the verdict. This study investigated the serial position effect in a judicial context. 1831 Swiss criminal judges received a filmed mock trial with a specific order stemming from the combination of 3 witnesses: a forensic expert, an eyewitness and an alibi witness. The evidence order was completely counterbalanced and each witness represented a different type of testimony chosen in accordance with the legal practice. If judges rendered their verdict on the basis of the first witness, a primacy effect would be observed. Conversely, if the last testimony would be preponderant, a recency effect would influence their judgment. Results showed a recency effect based on a defence eyewitness whose placement in the last position provoked significantly less condemnations. Furthermore, the probative value estimated by the judges for each piece of evidence was not associated with its serial impact. Results are discussed in relation to legal decision-making and the identification of a central witness mediating order effects.

  14. Nonlinear Process Fault Diagnosis Based on Serial Principal Component Analysis.

    2018-03-01

    Many industrial processes contain both linear and nonlinear parts, and kernel principal component analysis (KPCA), widely used in nonlinear process monitoring, may not offer the most effective means for dealing with these nonlinear processes. This paper proposes a new hybrid linear-nonlinear statistical modeling approach for nonlinear process monitoring by closely integrating linear principal component analysis (PCA) and nonlinear KPCA using a serial model structure, which we refer to as serial PCA (SPCA). Specifically, PCA is first applied to extract PCs as linear features, and to decompose the data into the PC subspace and residual subspace (RS). Then, KPCA is performed in the RS to extract the nonlinear PCs as nonlinear features. Two monitoring statistics are constructed for fault detection, based on both the linear and nonlinear features extracted by the proposed SPCA. To effectively perform fault identification after a fault is detected, an SPCA similarity factor method is built for fault recognition, which fuses both the linear and nonlinear features. Unlike PCA and KPCA, the proposed method takes into account both linear and nonlinear PCs simultaneously, and therefore, it can better exploit the underlying process's structure to enhance fault diagnosis performance. Two case studies involving a simulated nonlinear process and the benchmark Tennessee Eastman process demonstrate that the proposed SPCA approach is more effective than the existing state-of-the-art approach based on KPCA alone, in terms of nonlinear process fault detection and identification.

  15. Woody Allen, serial schlemiel ?

    2011-04-01

    Full Text Available Woody Allen a développé au fil des années une persona cinématographique de schlemiel new-yorkais aisément reconnaissable par le spectateur. Elle marque nombre de ses films, qu’il y apparaisse en tant qu’acteur ou y dirige des substituts comédiens comme déclinaisons de lui-même. Si cette figure prototypique est le fondement de la sérialité dans sa filmographie, il est des traits stylistiques qui en portent trace tout au long de son œuvre : la récurrence annuelle de ses réalisations, la signature formelle symbolisée par ses génériques à la typographie singulière, le rythme de ses dialogues ponctués d’interjections et l’usage de l’autocitation sont autant de procédés qui marquent son cinéma d’un sceau très personnel. Ils fonctionnent comme des clins d’œil au spectateur qui reçoit dès lors LE Woody Allen millésimé comme une invitation à retrouver son microcosme. Ainsi la sérialité se pose comme à la fois initiale et conséquentielle de son système filmique, processus de création unique dans le cinéma américain.Woody Allen has long constructed a cinematographic persona of schlemiel New- Yorker that the audience can easily identify. It impacts most of his films, whether he stars in them or directs “substitute” actors to impersonate his character. If this prototypical figure is the basis of seriality in his cinematography, serial stylistic features can also be found all along his career: the annual recurrence of his productions, the formal signature symbolised by the typography of his singular credit titles, his rhythmical interjection-punctuated dialogues and the use of self-quotation imprint a very personal seal upon his movies. They all work as a recognition signals for the audience who thus receive THE Woody Allen vintage as an invitation to re-enter his microcosm. Seriality is then both initial and consequential to his cinematographic system, a unique creative process in American film history.

    2008-07-01

    An exaggerated recency effect (ie, disproportionate recall of last-presented items) has been consistently observed in the word list learning of patients with Alzheimer's disease (AD). Our study sought to determine whether there were similar alterations in serial position learning among asymptomatic persons at risk for AD as a result of parental family history. Subjects included 623 asymptomatic middle-aged children of patients with AD (median, 53 years) and 157 control participants whose parents survived to at least age 70 without AD or other memory disorders. All participants were administered the Rey Auditory Verbal Learning Test, which requires learning and recall of 15 unrelated nouns. There was no significant difference in total words recalled between the AD children and control groups. However, compared with controls, AD children exhibited a significantly greater tendency to recall words from the end (recency) versus beginning (primacy) of the list. Serial position effects were unrelated to apolipoprotein allele epsilon 4 or depressive symptoms. Asymptomatic persons at risk for AD by virtue of family history do not show a difference in total words recalled compared with controls, but they exhibit a distinctly different serial position curve, suggesting greater reliance on immediate as opposed to episodic memory. This is the same serial position pattern observed in mild AD, seen here in reduced severity. Longitudinal follow-up is planned to determine whether changes in serial position patterns are a meaningful marker for preclinical detection of AD.

    2015-01-01

    The present study investigated long-term serial-order learning impairments, operationalized as reduced Hebb repetition learning (HRL), in people with dyslexia. In a first multi-session experiment, we investigated both the persistence of a serial-order learning impairment as well as the long-term retention of serial-order representations, both in a group of Dutch-speaking adults with developmental dyslexia and in a matched control group. In a second experiment, we relied on the assumption that HRL mimics naturalistic word-form acquisition and we investigated the lexicalization of novel word-forms acquired through HRL. First, our results demonstrate that adults with dyslexia are fundamentally impaired in the long-term acquisition of serial-order information. Second, dyslexic and control participants show comparable retention of the long-term serial-order representations in memory over a period of 1 month. Third, the data suggest weaker lexicalization of newly acquired word-forms in the dyslexic group. We discuss the integration of these findings into current theoretical views of dyslexia.

    Directory of Open Access Journals (Sweden)

    Gabriela Kovácsová

    2017-07-01

    Full Text Available Serial (femtosecond crystallography at synchrotron and X-ray free-electron laser (XFEL sources distributes the absorbed radiation dose over all crystals used for data collection and therefore allows measurement of radiation damage prone systems, including the use of microcrystals for room-temperature measurements. Serial crystallography relies on fast and efficient exchange of crystals upon X-ray exposure, which can be achieved using a variety of methods, including various injection techniques. The latter vary significantly in their flow rates – gas dynamic virtual nozzle based injectors provide very thin fast-flowing jets, whereas high-viscosity extrusion injectors produce much thicker streams with flow rates two to three orders of magnitude lower. High-viscosity extrusion results in much lower sample consumption, as its sample delivery speed is commensurate both with typical XFEL repetition rates and with data acquisition rates at synchrotron sources. An obvious viscous injection medium is lipidic cubic phase (LCP as it is used for in meso membrane protein crystallization. However, LCP has limited compatibility with many crystallization conditions. While a few other viscous media have been described in the literature, there is an ongoing need to identify additional injection media for crystal embedding. Critical attributes are reliable injection properties and a broad chemical compatibility to accommodate samples as heterogeneous and sensitive as protein crystals. Here, the use of two novel hydrogels as viscous injection matrices is described, namely sodium carboxymethyl cellulose and the thermo-reversible block polymer Pluronic F-127. Both are compatible with various crystallization conditions and yield acceptable X-ray background. The stability and velocity of the extruded stream were also analysed and the dependence of the stream velocity on the flow rate was measured. In contrast with previously characterized injection media, both new

    Full Text Available Abstract Background Although multi-sector policy is a promising strategy to create environments that stimulate physical activity among children, little is known about the feasibility of such a multi-sector policy approach. The aims of this study were: to identify a set of tangible (multi-sector policy measures at the local level that address environmental characteristics related to physical activity among children; and to assess the feasibility of these measures, as perceived by local policy makers. Methods In four Dutch municipalities, a Delphi study was conducted among local policy makers of different policy sectors (public health, sports, youth and education, spatial planning/public space, traffic and transportation, and safety. In the first Delphi round, respondents generated a list of possible policy measures addressing three environmental correlates of physical activity among children (social cohesion, accessibility of facilities, and traffic safety. In the second Delphi round, policy makers weighted different feasibility aspects (political feasibility, cultural/community acceptability, technical feasibility, cost feasibility, and legal feasibility and assessed the feasibility of the policy measures derived from the first round. The third Delphi round was aimed at reaching consensus by feedback of group results. Finally, one overall feasibility score was calculated for each policy measure. Results Cultural/community acceptability, political feasibility, and cost feasibility were considered most important feasibility aspects. The Delphi studies yielded 16 feasible policy measures aimed at physical and social environmental correlates of physical activity among children. Less drastic policy measures were considered more feasible, whereas environmental policy measures were considered less feasible. Conclusions This study showed that the Delphi technique can be a useful tool in reaching consensus about feasible multi-sector policy measures. The

    Full Text Available European wine policy is a significant factor influencing winemakers in the European Union. This paper examines perception of this policy by winemakers and other persons working in Czech wine sector on the sample of respondents. Methodological triangulation consisting of non-structured interview and semantic differential was chosen. Field research was carried out, therefore the study uses primary data. Application of the methodology along with the method of evaluation of data creates an original approach which may be applied on several other research questions. General perception of European Wine Policy is complemented with its impact on competitiveness, practical running of vineyards and winery and on future development of winery. Data is statistically evaluated within categories of respondents. Special emphasis is placed on direct payments as a controversial factor of the policy. The policy is perceived as bureaucratic (“all respondents” x = 4.56, and among micro winemakers discriminating (x = 4.5, selfish (x = 4.5 and malfunctioning (x = 3.5. “Professional” winemakers perceive the impact on competitiveness in the Czech market as rather positive (x = 2.67. This study represents pilot research on perception of European Wine Policy by owners of wineries, viticulturists, micro winemakers, a sommelier and a representative of marketing-supporting institution, conducted in the Czech Republic. The author also outlines further direction of research, as the topic is not paid enough scientific attention.

  14. Policy and practice of occupational rehabilitation in Hong Kong and Guangzhou--a comparative study.

    2008-01-01

    The objective of this paper is to compare social policy on occupational rehabilitation services in two mega industrial cities in southern China: Hong Kong and Guangzhou. Comparative policy study was employed as the research and analytical method in this paper. Aim, finance, target, coverage, organization and administration, service delivery and provision of the occupational rehabilitation policy and its linkages with industrial injury compensation system and re-employment policy in the two cities were critically reviewed and compared. The results of the study reflect that the Guangzhou policy is more aggressive and more tailor-made to the specific needs of occupational rehabilitation compared to the Hong Kong policy, whereas occupational rehabilitation in Hong Kong has long been developed and knowledge and skills in the occupational rehabilitation service are more mature and fruitful. Based on the research findings, it is concluded that through experience sharing and exchange, there will be more mutual understanding regarding the system, practice, success, faults and limitations in the two cities, as well as awareness of alternative courses of action. These will help in the better development of occupational rehabilitation services with the aims to safeguard the rights and wellbeing of workers in both cities.

  15. Credible baseline analysis for multi-model public policy studies

    1981-01-01

    The nature of public decision-making and resource allocation is such that many complex interactions can best be examined and understood by quantitative analysis. Most organizations do not possess the totality of models and needed analytical skills to perform detailed and systematic quantitative analysis. Hence, the need for coordinated, multi-organization studies that support public decision-making has grown in recent years. This trend is expected not only to continue, but to increase. This paper describes the authors' views on the process of multi-model analysis based on their participation in an analytical exercise, the ORNL/MITRE Study. One of the authors was the exercise coordinator. During the study, the authors were concerned with the issue of measuring and conveying credibility of the analysis. This work led them to identify several key determinants, described in this paper, that could be used to develop a rating of credibility.

    % SSB tax. Neither the MMC nor the individual national economic policies would significantly reduce CVD socio-economic disparities. However, the SNAP-targeted intervention might potentially reduce CVD disparities between SNAP participants and SNAP-ineligible individuals, by approximately 8% (10 DPPs per 100,000 population. The combined policy approach might save more lives than any single policy studied (approximately 230,000 DPPs by 2030 while also significantly reducing disparities, by approximately 6% (7 DPPs per 100,000 population. Limitations include our effect estimates in the model; these estimates use interventional and prospective observational studies (not exclusively randomised controlled trials. They are thus imperfect and should be interpreted as the best available evidence. Another key limitation is that we considered only CVD outcomes; the policies we explored would undoubtedly have additional beneficial effects upon other diseases. Further, we did not model or compare the cost-effectiveness of each proposed policy.Fiscal strategies targeting diet might substantially reduce CVD burdens. A national 10% F&V subsidy would save by far the most lives, while a 30% F&V subsidy targeting SNAP participants would most reduce socio-economic disparities. A combined policy would have the greatest overall impact on both mortality and socio-economic disparities.

    Georgia has limited tobacco control policies, particularly in the area of smoke-free public policies, which may influence the adoption of smoke-free home rules. We qualitatively examined knowledge about and reactions to public and personal smoke-free policies among Tbilisi residents. In Spring 2014, we conducted six focus groups among 47 total participants--two among male smokers, one among male nonsmokers, two among female smokers, and one among female nonsmokers. Our sample was 48.9% male and 70.2% past 30-day smokers. Most believed that SHS was dangerous, with particular concern regarding the impact of SHS on children and pregnant women. Many had misconceptions about how to protect others from SHS and the effectiveness of some approaches. Many indicated that they had some type of home rules, but few reported a complete ban on smoking in the home. Even when some restrictions were in place, they rarely were effective or enforced. Common concerns about the partial smoke-free public policy in Georgia included its economic impact, perceived discrimination among smokers, and the policy being against the Georgian culture. These concerns were heightened when participants were asked about the possible implementation of a complete smoke-free policy. Educational programs are needed to promote smoke-free policies in Georgia.

  1. Developing national obesity policy in middle-income countries: a case study from North Africa

    Background The prevalence of overweight and obesity is a rapidly growing threat to public health in both Morocco and Tunisia, where it is reaching similar proportions to high-income countries. Despite this, a national strategy for obesity does not exist in either country. The aim of this study was to explore the views of key stakeholders towards a range of policies to prevent obesity, and thus guide policy makers in their decision making on a national level. Methods Using Multicriteria Mapping, data were gathered from 82 stakeholders (from 33 categories in Morocco and 36 in Tunisia) who appraised 12 obesity policy options by reference to criteria of their own choosing. Results The feasibility of policies in practical or political terms and their cost were perceived as more important than how effective they would be in reducing obesity. There was most consensus and preference for options targeting individuals through health education, compared with options that aimed at changing the environment, i.e. modifying food supply and demand (providing healthier menus/changing food composition/food sold in schools); controlling information (advertising controls/mandatory labelling) or improving access to physical activity. In Tunisia, there was almost universal consensus that at least some environmental-level options are required, but in Morocco, participants highlighted the need to raise awareness within the population and policy makers that obesity is a public health problem, accompanied by improving literacy before such measures would be accepted. Conclusion Whilst there is broad interest in a range of policy options, those measures targeting behaviour change through education were most valued. The different socioeconomic, political and cultural contexts of countries need to be accounted for when prioritizing obesity policy. Obesity was not recognized as a major public health priority; therefore, convincing policy makers about the need to prioritize action to prevent

  2. State of Data Guidance in Journal Policies: A Case Study in Oncology

    Directory of Open Access Journals (Sweden)

    Deborah H. Charbonneau

    2015-06-01

    Full Text Available This article reports the results of a study examining the state of data guidance provided to authors by 50 oncology journals. The purpose of the study was the identification of data practices addressed in the journals’ policies. While a number of studies have examined data sharing practices among researchers, little is known about how journals address data sharing. Thus, what was discovered through this study has practical implications for journal publishers, editors, and researchers. The findings indicate that journal publishers should provide more meaningful and comprehensive data guidance to prospective authors. More specifically, journal policies requiring data sharing, should direct researchers to relevant data repositories, and offer better metadata consultation to strengthen existing journal policies. By providing adequate guidance for authors, and helping investigators to meet data sharing mandates, scholarly journal publishers can play a vital role in advancing access to research data.

  7. Cluster Policy in the Light of Institutional Context—A Comparative Study of Transition Countries

    Directory of Open Access Journals (Sweden)

    Tine Lehmann

    2015-10-01

    Full Text Available The business environment in transition countries is often extraordinarily challenging for companies. The transition process these countries find themselves in leads to constant changes in the institutional environment. Hence, institutional voids prevail. These institutional voids cause competitive disadvantages for small and medium enterprises. Cluster policy can address these competitive disadvantages. As cluster policy generally aims at supporting companies’ competitive advantage by spurring innovation and productivity, it can help to bridge institutional voids. This article’s research question aims at analyzing and comparing cluster policies in the institutional context of two transition countries (Serbia and Tunisia and analyzes to what extent cluster policies in these two countries are adapted to institutional voids prevailing there. The case studies offer insights into apparent difficulties of clusters in bridging formal institutional voids, as well as, notably, into the informal void of skill mismatches in the labor market. Still, for some specific voids, clusters do at least implicitly assume a bridging role. While the cluster policies examined do not explicitly target the institutional voids identified, cluster management can—in the course of time—align its service offering more closely with these voids. Bottom-up designed cluster policies can play an especially important role in such an evolution towards bridging institutional voids.

  8. Serial crystallography captures enzyme catalysis in copper nitrite reductase at atomic resolution from one crystal

    Directory of Open Access Journals (Sweden)

    Sam Horrell

    2016-07-01

    Full Text Available Relating individual protein crystal structures to an enzyme mechanism remains a major and challenging goal for structural biology. Serial crystallography using multiple crystals has recently been reported in both synchrotron-radiation and X-ray free-electron laser experiments. In this work, serial crystallography was used to obtain multiple structures serially from one crystal (MSOX to study in crystallo enzyme catalysis. Rapid, shutterless X-ray detector technology on a synchrotron MX beamline was exploited to perform low-dose serial crystallography on a single copper nitrite reductase crystal, which survived long enough for 45 consecutive 100 K X-ray structures to be collected at 1.07–1.62 Å resolution, all sampled from the same crystal volume. This serial crystallography approach revealed the gradual conversion of the substrate bound at the catalytic type 2 Cu centre from nitrite to nitric oxide, following reduction of the type 1 Cu electron-transfer centre by X-ray-generated solvated electrons. Significant, well defined structural rearrangements in the active site are evident in the series as the enzyme moves through its catalytic cycle, namely nitrite reduction, which is a vital step in the global denitrification process. It is proposed that such a serial crystallography approach is widely applicable for studying any redox or electron-driven enzyme reactions from a single protein crystal. It can provide a `catalytic reaction movie' highlighting the structural changes that occur during enzyme catalysis. The anticipated developments in the automation of data analysis and modelling are likely to allow seamless and near-real-time analysis of such data on-site at some of the powerful synchrotron crystallographic beamlines.

  9. Serial femtosecond X-ray diffraction of enveloped virus microcrystals

    2015-07-01

    Full Text Available Serial femtosecond crystallography (SFX using X-ray free-electron lasers has produced high-resolution, room temperature, time-resolved protein structures. We report preliminary SFX of Sindbis virus, an enveloped icosahedral RNA virus with ∼700 Å diameter. Microcrystals delivered in viscous agarose medium diffracted to ∼40 Å resolution. Small-angle diffuse X-ray scattering overlaid Bragg peaks and analysis suggests this results from molecular transforms of individual particles. Viral proteins undergo structural changes during entry and infection, which could, in principle, be studied with SFX. This is an important step toward determining room temperature structures from virus microcrystals that may enable time-resolved studies of enveloped viruses.

    This study is composed mainly of the current status of international non-proliferation, the NPT extension, IAEA Status, the circumstances of nuclear export control system, and the Vienna convention and London convention. The recent circumstances of the NPT have been analyzed. We established counter measures and strategies on the NPT extension conference. After reviewing the international export control system of NSG members, we suggested the factors which should be involved in the nuclear export control system. Also, U.S. systems on retransferring were intensively reviewed. In connection with the challenges coped with by the IAEA, several agenda have been reviewed and analyzed: the financing status of the Agency; the program 93+2 for the strengthening of effectiveness and improving of efficiency in the safeguards system. In connection with the amendment work of the Vienna Convention, we studied the major contents of four proposals which were suggested. In the case of the London Convention, the causes of maritime pollution and the kinds of sea dumping material were investigated. 3 figs, 13 tabs, 66 refs. (Author)

    2009-01-01

    A new configuration of manure digesters for improving biogas production has been investigated in laboratory scale. A single thermophilic continuous-flow stirred tank reactor (CSTR) operated with a hydraulic retention time (HRT) of 15 days was compared to a serial CSTR configuration with volume...... distribution ratio of 80/20 and 90/10, and total HRT of 15 days. The results showed that the serial CSTR could obtain 11% higher biogas yield compared to the single CSTR. The increased biogas yield in the serial CSTR was mainly from the second reactor, which accounted for 16% and 12% of total biogas yield...... in the 90/10 and 80/20 configuration, respectively. VFA concentration in the serial CSTR was high in the first reactor but very low in the second reactor. The results from organic pulse load test showed that the second reactor in serial CSTR helped utilizing VFA produced from overloading in the first...

    International Nuclear Information System (INIS)

    Garrity, P.J.

    1994-01-01

    This paper is concerned with those studies and analyses that affected early NATO nuclear policy and force structure. The discussion focuses specifically on two open-quotes benchmarkclose quotes activities. Project VISTA and Project ATTACK. These two studies were chosen less because one can document their direct impact on NATO nuclear policy and more because they capture the state of thinking about tactical nuclear weapons at a particular point of time. Project VISTA offers an especially important benchmark in this respect. Project ATTACK is a rather different kind of benchmark. It is not a pathbreaking study. It is much narrower and more technical than VISTA. It appears to have received no public attention. Project ATTACK is interesting because it seems to capture a open-quotes nuts-and-boltsclose quotes feel for how U.S. (and thereby NATO) theater nuclear policy was evolving prior to MC 48. The background and context for Project VISTA and Project ATTACK are presented and discussed

    2011-11-01

    During the rapid economic development in China, ambient air pollutants in major cities, including PM10 (particulate matter with aerodynamic diameter air pollution levels in China are still at the higher end of the world level. Less information is available regarding changes in national levels of other pollutants such as PM2.5 and ozone. The Chinese Ministry of Environmental Protection (MOEP) set an index for "controlling/reducing total SO2 emissions" to evaluate the efficacy of air pollution control strategy in the country. Total SO2 emissions declined for the first time in 2007. Chinese epidemiologic studies evidenced adverse health effects of ambient air pollution similar to those reported from developed countries, though risk estimates on mortality/morbidity per unit increase of air pollutant are somewhat smaller than those reported in developed countries. Disease burden on health attributable to air pollution is relatively greater in China because of higher pollution levels. Improving ambient air quality has substantial and measurable public health benefits in China. It is recommended that the current Chinese air quality standards be updated/revised and the target for "controlling/reducing total SO2 emissions" be maintained and another target for "reducing total NO2 emissions" be added in view of rapid increase in motor vehicles. Continuous and persistent efforts should be taken to improve ambient air quality.

    Månsson, Josefin

    2014-07-01

    This study examines how online discussions on drug policy are formulating an oppositional cannabis discourse in an otherwise prohibitionist country like Sweden. The focus of the paper is to identify demands for an alternative cannabis policy as well as analysing how these demands are linked to governance. The empirical material is 56 discussion-threads from the online message-board Flashback Forum that were active during the first eight months of 2012. Discourse theory was used to locate the discourse, and governmentality theory was used to locate the political belonging of the discourse. On Flashback Forum demands for a new cannabis policy are articulated in opposition to Swedish prohibitionist discourse. The oppositional discourse is constructed around the nodal points cannabis, harm, state and freedom that fill legalisation/decriminalisation/liberalisation with meaning. The nodal points are surrounded by policy demands that get their meaning through the particular nodal. These demands originate from neo-liberal and welfarist political rationalities. Neo-liberal and welfarist demands are mixed, and participants are simultaneously asking for state and individual approaches to handle the cannabis issue. Swedish online discourse on cannabis widens the scope beyond the confines of drug policy to broader demands such as social justice, individual choice and increased welfare. These demands are not essentially linked together and many are politically contradictory. This is also significant for the discourse; it is not hegemonised by a political ideology. The discourse is negotiated between the neo-liberal version of an alternative policy demanding individual freedom, and the welfarist version demanding social responsibility. This implies the influence of the heritage from the social-democratic discourse, centred on state responsibility, which have been dominating Swedish politics in modern times. Consequently, this study refutes that the demand for a new cannabis

    It is known that fluoridation has a contextual effect on oral health socioeconomic inequalities, but broad public policies have not been investigated. Thus, the aim of this study was to determine the effects of municipal public policies on oral health across different social strata. This was a cross-sectional study with 7328 12-year-old children and 5445 15-19-year-old adolescents from 177 Brazilian municipalities. Information at municipal level was collated for dental services, educational services, sanitation and water fluoridation. The main individual-level exposure was the disposable equivalent household income. The dichotomous outcomes were as follows: untreated dental caries (≥1 tooth), missing teeth (≥1 tooth) and filled teeth (≥1 tooth). Analyses were carried out using multilevel logistic regression. Interaction terms were tested between individual-level income and policy variables. The prevalence of untreated dental caries, missing and filled teeth was 47.0%, 15.1% and 47.5%, respectively. There was no significant interaction between income and policy indicators. Individuals living in municipalities with no water fluoridation had 1.42 (95% CI: 1.08-1.86) higher odds of having untreated dental caries; the odds ratio (OR) for those in municipalities with less education policies was 1.36 (95% CI: 1.07-1.73); those in municipalities with less sanitation had OR = 1.05 (95% CI: 0.78-1.40); and those in municipalities with less dental care had OR = 1.36 (95% CI: 1.02-1.80). Fluoridation and policies about sanitation, education and dental care were similarly associated with oral health in different social strata. Other policies on social and economic fields may be further explored. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To examine the efficacy of different methods (ie, in-class policy reading; in-class policy reading and discussion; no reading or discussion) to deliver campus sexual misconduct policy information to students on 7 campuses. A total of 1,195 participants at 7 colleges and universities participated in the study from August to October 2014. Participants were randomly assigned at the class level and completed pretest and posttest surveys assessing knowledge of campus policy and resources and confidence to seek help for sexual assault. Students exposed to a larger dosage of material (in-class policy reading plus discussion) showed greater positive changes in attitudes and knowledge than students who did not receive information or were only read the policy. However, on some indices, students who were only read the policy showed positive outcomes compared with students receiving no intervention. Colleges and universities must use engaging methods to disseminate campus sexual misconduct policies to students.

    Dreaming-a particular form of consciousness that occurs during sleep-undergoes major changes in the course of the night. We aimed to outline state-dependent features of consciousness using a paradigm with multiple serial awakenings/questionings that allowed for within as well as between subject comparisons. Seven healthy participants who spent 44 experimental study nights in the laboratory were awakened by a computerized sound at 15-30 min intervals, regardless of sleep stage, and questioned for the presence or absence of sleep consciousness. Recall without content ("I was experiencing something but do not remember what") was considered separately. Subjects had to indicate the content of the most recent conscious experience prior to the alarm sound and to estimate its duration and richness. We also assessed the degree of thinking and perceiving, self- and environment-relatedness and reflective consciousness of the experiences. Of the 778 questionings, 5% were performed during wakefulness, 2% in stage N1, 42% in N2, 33% in N3, and 17% in rapid eye movement (REM) sleep. Recall with content was reported in 34% of non-REM and in 77% of REM sleep awakenings. Sleep fragmentation inherent to the study design appeared to only minimally affect the recall of conscious experiences. Each stage displayed a unique combination of characteristic features of sleep consciousness. In conclusion, our serial awakening paradigm allowed us to collect a large and representative sample of conscious experiences across states of being. It represents a time-efficient method for the study of sleep consciousness that may prove particularly advantageous when combined with techniques such as functional MRI and high-density EEG.

    Full Text Available Local spatial policy in Poland is based on the obligatory document, which is a study of conditions and directions of spatial management. In this document, particular communities define land use forms according to specific functions. One of the fundamental functions, which appear in the study, is housing. Communities assign various, usually very big, percentage of their areas for housing. The research conducted by the author was aimed at answering the question: what is the connection between pro-housing policy in particular municipalities and the actual new housing investments? This problem was analysed on the example of communities in Łódź agglomeration.

    Scotland is the first country in the world to pass legislation introducing a minimum unit price (MUP) for alcohol in an attempt to reduce consumption and associated harms by increasing the price of the cheapest alcohol. We investigated the competing ways in which policy stakeholders presented the debate. We then established whether a change in framing helped explain the policy's emergence. We conducted a detailed policy case study through analysis of evidence submitted to the Scottish parliament, and in-depth, one-to-one interviews (n = 36) with politicians, civil servants, advocates, researchers, and industry representatives. Public- and voluntary-sector stakeholders tended to support MUP, while industry representatives were more divided. Two markedly different ways of presenting alcohol as a policy problem were evident. Critics of MUP (all of whom were related to industry) emphasized social disorder issues, particularly among young people, and hence argued for targeted approaches. In contrast, advocates for MUP (with the exception of those in industry) focused on alcohol as a health issue arising from overconsumption at a population level, thus suggesting that population-based interventions were necessary. Industry stakeholders favoring MUP adopted a hybrid framing, maintaining several aspects of the critical framing. Our interview data showed that public health advocates worked hard to redefine the policy issue by deliberately presenting a consistent alternative framing. Framing alcohol policy as a broad, multisectoral, public health issue that requires a whole-population approach has been crucial to enabling policymakers to seriously consider MUP, and public health advocates intentionally presented alcohol policy in this way. This reframing helped prioritize public health considerations in the policy debate and represents a deliberate strategy for consideration by those advocating for policy change around the world and in other public health areas. © 2014

    The Caribbean has the highest prevalence rates of HIV/AIDS outside sub-Saharan Africa, and a broad literature suggests an ecological association between tourism areas and sexual vulnerability. Tourism employees have been shown to engage in high rates of sexual risk behaviours. Nevertheless, no large-scale or sustained HIV prevention interventions have been conducted within the tourism industry. Policy barriers and resources are under-studied. In order to identify the policy barriers and resources for HIV prevention in the tourism sector, our research used a participatory approach involving a multisectoral coalition of representatives from the tourism industry, government, public health and civil society in the Dominican Republic. We conducted 39 in-depth semi-structured interviews with policy makers throughout the country focusing on: prior experiences with HIV prevention policies and programmes in the tourism sector; barriers and resources for such policies and programmes; and future priorities and recommendations. Findings suggest perceptions among policy makers of barriers related to the mobile nature of tourism employees; the lack of centralized funding; fear of the 'image problem' associated with HIV; and the lack of multisectoral policy dialogue and collaboration. Nevertheless, prior short-term experiences and changing attitudes among some private sector tourism representatives suggest emerging opportunities for policy change. We argue that the time is ripe for dialogue across the public-private divide in order to develop regulatory mechanisms, joint responsibilities and centralized funding sources to ensure a sustainable response to the HIV-tourism linkage. Policy priorities should focus on incorporating HIV prevention as a component of occupational health; reinforcing workers' health care rights as guaranteed by existing law; using private sector tourism representatives who support HIV prevention as positive role models for national campaigns; and

    Full Text Available Imaging entire mouse brains at submicron resolution has historically been a challenging undertaking and largely confined to the province of dedicated atlasing initiatives. The has limited systematic investigations into important areas of neuroscience, such as neural circuits, brain mapping and neurodegeneration. In this paper, we describe in detail Serial Two-Photon (STP tomography, a robust, reliable method for imaging entire brains with histological detail. We provide examples of how the basic methodology can be extended to other imaging modalities, such as optical coherence tomography, in order to provide unique contrast mechanisms. Furthermore we provide a survey of the research that STP tomography has enabled in the field of neuroscience, provide examples of how this technology enables quantitative whole brain studies, and discuss the current limitations of STP tomography-based approaches

    The concentration of hexachlorophene was determined in serial blood samples taken from seven premature infants washed with pHisoHex. Results indicated that after a single wash with 5ml of pHisoHex, blood concentrations reached a maximum of 0.75-1.20mug/ml two to four days after application. The results obtained in this study confirm that the dermal absorption of hexachlorophene is greater in premature than in full-term infants. Use of hexachlorophene for infants. Use of hexachlorophene for infants of birth weight less than 2kg has now been discontinued at Queen Mary Hospital and the amount of pHisoHex used in the initial toileting of infants with birth weight more than 2kg has been limited to a single application of 5ml.

    X-ray free electron lasers (XFELs) have the potential to revolutionize macromolecular structural biology due to the unique combination of spatial coherence, extreme peak brilliance, and short duration of X-ray pulses. A recently emerged serial femtosecond (fs) crystallography (SFX) approach using XFEL radiation overcomes some of the biggest hurdles of traditional crystallography related to radiation damage through the diffraction-before-destruction principle. Intense fs XFEL pulses enable high-resolution room-temperature structure determination of difficult-to-crystallize biological macromolecules, while simultaneously opening a new era of time-resolved structural studies. Here, we review the latest developments in instrumentation, sample delivery, data analysis, crystallization methods, and applications of SFX to important biological questions, and conclude with brief insights into the bright future of structural biology using XFELs.

    1983-01-01

    A method is described for the serial cultivation of adult human hair follicle keratinocytes. Plucked scalp hair follicles, placed on bovine eye lens capsules as a growth substrate, give rise to quickly expanding colonies within a few days. After trypsinization, the cells are replated with irradiated 3T3 cells as 'feeders'. Using this combination of techniques the keratinocytes can be subcultured up to four times. In this way about 10(7) keratinocytes can be generated from one single hair follicle. Moreover, the technique enables cryogenic storage of the cells, allowing for instance, convenient transportation. Subcultured hair follicle keratinocytes can be plated on glass coverslips. This allows immunofluorescence studies. The keratin cytoskeletons visualized using an antiserum against human keratin.

  18. Bridging environmental and financial cost of dairy production: A case study of Irish agricultural policy.

    2018-02-15

    The Irish agricultural policy 'Food Harvest 2020' is a roadmap for sectoral expansion and Irish dairy farming is expected to intensify, which could influence the environmental and economic performance of Irish milk production. Evaluating the total environmental impacts and the real cost of Irish milk production is a key step towards understanding the possibility of sustainable production. This paper addresses two main issues: aggregation of environmental impacts of Irish milk production by monetization, to understand the real cost of Irish milk production, including the environmental costs; and the effect of the agricultural policy 'Food Harvest 2020' on total cost (combining financial cost and environmental cost) of Irish milk production. This study used 2013 Irish dairy farming as a baseline, and defined 'bottom', 'target' and 'optimum' scenarios, according to the change of elementary inputs required to meet agricultural policy ambitions. The study demonstrated that the three monetization methods, Stepwise 2006, Eco-cost 2012 and EPS 2000, could be used for aggregating different environmental impacts into monetary unit, and to provide an insight for evaluating policy related to total environmental performance. The results showed that the total environmental cost of Irish milk production could be greater than the financial cost (up to €0.53/kg energy corrected milk). The dairy expansion policy with improved herbage utilization and fertilizer application could reduce financial cost and minimize the total environmental cost of per unit milk produced.

  19. Serial dependence promotes object stability during occlusion

    Liberman, Alina; Zhang, Kathy; Whitney, David

    2016-01-01

    Object identities somehow appear stable and continuous over time despite eye movements, disruptions in visibility, and constantly changing visual input. Recent results have demonstrated that the perception of orientation, numerosity, and facial identity is systematically biased (i.e., pulled) toward visual input from the recent past. The spatial region over which current orientations or face identities are pulled by previous orientations or identities, respectively, is known as the continuity field, which is temporally tuned over the past several seconds (Fischer & Whitney, 2014). This perceptual pull could contribute to the visual stability of objects over short time periods, but does it also address how perceptual stability occurs during visual discontinuities? Here, we tested whether the continuity field helps maintain perceived object identity during occlusion. Specifically, we found that the perception of an oriented Gabor that emerged from behind an occluder was significantly pulled toward the random (and unrelated) orientation of the Gabor that was seen entering the occluder. Importantly, this serial dependence was stronger for predictable, continuously moving trajectories, compared to unpredictable ones or static displacements. This result suggests that our visual system takes advantage of expectations about a stable world, helping to maintain perceived object continuity despite interrupted visibility. PMID:28006066

  20. Testing the associative-link hypothesis in immediate serial recall: Evidence from word frequency and word imageability effects.

    Two immediate serial recall experiments were conducted to test the associative-link hypothesis (Stuart & Hulme, 2000). We manipulated interitem association by varying the intralist latent semantic analysis (LSA) cosines in our 7-item study word lists, each of which consists of high- or low-frequency words in Experiment 1 and high- or low-imageability words in Experiment 2. Whether item recall performance was scored by a serial-recall or free-recall criterion, we found main effects of interitem association, word imageability, and word frequency. The effect of interitem association also interacted with the word frequency effect, but not with the word imageability effect. The LSA-cosinexword frequency interaction occurred in the recency, but not primacy, portion of the serial position curve. The present findings set explanatory boundaries for the associative-link hypothesis and we argue that both item- and associative-based mechanisms are necessary to account for the word frequency effect in immediate serial recall.

  1. Mortgage foreclosure and health disparities: serial displacement as asset extraction in African American populations.

    Science.gov (United States)

    Saegert, Susan; Fields, Desiree; Libman, Kimberly

    2011-06-01

    In this paper we offer a conceptualization of mortgage foreclosure as serial displacement by highlighting the current crisis in the context of historically repeated extraction of capital-economic, social, and human-from communities defined at different scales: geographically, socially, and that of embodied individuals. We argue that serial displacement is the loss of capital, physical resources, social integration and collective capacity, and psycho-social resources at each of these scales, with losses at one level affecting other levels. The repeated extraction of resources has negative implications for the health of individuals and groups, within generations as well as across generations, through the accumulation of loss over time. Our analysis of the foreclosure crisis as serial displacement for African American households in the United States begins with the "housing niche" model. We focus on the foreclosure crisis as an example of the interconnectedness of structured inequality in health and housing. Then we briefly review the history of policies related to racial inequality in homeownership in the twentieth and twenty-first centuries. We end with an analysis of the scales of displacement and the human, social, and capital asset extraction that accompany them.

  2. Gasoline-powered serial hybrid cars cause lower life cycle carbon emissions than battery cars

    2011-04-01

    Battery cars powered by grid electricity promise reduced life cycle green house gas (GHG) emissions from the automotive sector. Such scenarios usually point to the much higher emissions from conventional, internal combustion engine cars. However, today's commercially available serial hybrid technology achieves the well known efficiency gains from regenerative breaking, lack of gearbox, and light weighting - even if the electricity is generated onboard, from conventional fuels. Here, we analyze emissions for commercially available, state-of the-art battery cars (e.g. Nissan Leaf) and those of commercially available serial hybrid cars (e.g., GM Volt, at same size and performance). Crucially, we find that serial hybrid cars driven on (fossil) gasoline cause fewer life cycle GHG emissions (126g CO2e per km) than battery cars driven on current US grid electricity (142g CO2e per km). We attribute this novel finding to the significant incremental life cycle emissions from battery cars from losses during grid transmission, battery dis-/charging, and larger batteries. We discuss crucial implications for strategic policy decisions towards a low carbon automotive sector as well as relative land intensity when powering cars by biofuel vs. bioelectricity.

  3. Towards understanding the drivers of policy change: a case study of infection control policies for multi-drug resistant tuberculosis in South Africa.

    2017-05-30

    Explaining policy change is one of the central tasks of contemporary policy analysis. In this article, we examine the changes in infection control policies for multi-drug resistant tuberculosis (MDR-TB) in South Africa from the time the country made the transition to democracy in 1994, until 2015. We focus on MDR-TB infection control and refer to decentralised management as a form of infection control. Using Kingdon's theoretical framework of policy streams, we explore the temporal ordering of policy framework changes. We also consider the role of research in motivating policy changes. Policy documents addressing MDR-TB in South Africa over the period 1994 to 2014 were extracted. Literature on MDR-TB infection control in South Africa was extracted from PubMed using key search terms. The documents were analysed to identify the changes that occurred and the factors driving them. During the period under study, five different policy frameworks were implemented. The policies were meant to address the overwhelming challenge of MDR-TB in South Africa, contextualised by high prevalence of HIV infection, that threatened to undermine public health programmes and the success of antiretroviral therapy rollouts. Policy changes in MDR-TB infection control were supported by research evidence and driven by the high incidence and complexity of the disease, increasing levels of dissatisfaction among patients, challenges of physical, human and financial resources in public hospitals, and the ideologies of the political leadership. Activists and people living with HIV played an important role in highlighting the importance of MDR-TB as well as exerting pressure on policymakers, while the mass media drew public attention to infection control as both a cause of and a solution to MDR-TB. The critical factors for policy change for infection control of MDR-TB in South Africa were rooted in the socioeconomic and political environment, were supported by extensive research, and can be framed

  12. Convergence, Creative Industries and Civil Society Towards a New Agenda for Cultural Policy and Cultural Studies

    Directory of Open Access Journals (Sweden)

    Colin Mercer

    2009-10-01

    Full Text Available In this article I start with a personal experience "cameo" from 1996 in Australia and extrapolate from that some issues that remain relevant in the sometimes trou-bled relationship between cultural studies and cultural policy. These are encapsu-lated in the three "cs" of convergence, creative industries and civil society which provide a new context for both new research and new policy settings. The argu-ment is developed and situated in historical terms by examining the "cultural technologies", especially the newspaper, and subsequently print media in the 19th century, electronic media in the 20th century and digital media in the 21st century which provide the content, the technologies and the rituals for "imagining" our sense of place and belonging. This is then linked to ways of understanding culture and cultural technologies in the context of governmentality and the emergence of culture as a strategic object of policy with the aim of citizen- and population for-mation and management. This argument is then linked to four contemporary "testbeds" - cultural mapping and planning, cultural statistics and indicators, cul-tural citizenship and identity, and research of and for cultural policy - and priori-ties for cultural policy where cultural studies work has been extremely enabling and productive. The article concludes with an argument, derived from the early 20th century work of Patrick Geddes of the necessity of linking, researching, un-derstanding and operationalising the three key elements and disciplines of Folk (anthropology, Work (economics, and Place (geography in order to properly situate cultural policy, mapping and planning and their relationship to cultural studies and other disciplines.

  13. Addressing refugee health through evidence-based policies: a case study.

    The cumulative total of persons forced to leave their country for fear of persecution or organized violence reached an unprecedented 24.5 million by the end of 2015. Providing equitable access to appropriate health services for these highly diverse newcomers poses challenges for receiving countries. In this case study, we illustrate the importance of translating epidemiology into policy to address the health needs of refugees by highlighting examples of what works as well as identifying important policy-relevant gaps in knowledge. First, we formed an international working group of epidemiologists and health services researchers to identify available literature on the intersection of epidemiology, policy, and refugee health. Second, we created a synopsis of findings to inform a recommendation for integration of policy and epidemiology to support refugee health in the United States and other high-income receiving countries. Third, we identified eight key areas to guide the involvement of epidemiologists in addressing refugee health concerns. The complexity and uniqueness of refugee health issues, and the need to develop sustainable management information systems, require epidemiologists to expand their repertoire of skills to identify health patterns among arriving refugees, monitor access to appropriately designed health services, address inequities, and communicate with policy makers and multidisciplinary teams.

  14. The (limited) political influence of ecological economics. A case study on Dutch environmental policies

    International Nuclear Information System (INIS)

    Boezeman, Daan; Leroy, Pieter; Maas, Rob; Kruitwagen, Sonja

    2010-01-01

    Although the ecological economics (EE) discourse attempts to influence environmental policy, empirical studies have concluded that its success in this endeavour has been limited thus far. In the Netherlands, however, two EE-related policy concepts, Environmental Utilisation Space and Ecological Footprint, were strongly present in environmental policy during certain periods in time, but subsequently disappeared from the environmental agenda. The central question of this article is how these ups and downs of the EE concepts can be understood: which factors determine their rise on and fall from the policy agenda over time? To answer this question, this article offers a conceptual model informed by the approaches in political science on framing, agenda-setting and knowledge utilisation. We conclude that the interplay of concept-specific characteristics, the formation of coalitions around the concept and contextual variables explain the rise and fall of the aforementioned concepts. A match between the dominant policy frame and the core elements of the concept provides the opportunity for the two concepts to be pushed on the agenda. We observe the alternation of 'constraining' frames, which allows for EE concepts to survive, and 'reconciling' frames, which block agenda entrance for EE concepts. Furthermore, the alternation of these frames seems to correlate with economic and public environmental attention cycles in the Netherlands. (author)

    Infrastructure development does not only affect the economic aspect, but also social and environmental, those are the main dimensions of sustainable development. Many aspects and actors involved in urban infrastructure development requires a comprehensive and integrated policy towards sustainability. Therefore, it is necessary to formulate an infrastructure development policy that considers various dimensions of sustainable development. The main objective of this research is to formulate policy of sustainable infrastructure development. In this research, urban infrastructure covers transportation, water systems (drinking water, storm water, wastewater), green open spaces and solid waste. This research was conducted in Bandarlampung City. This study use a comprehensive modeling, namely the Multi Dimensional Scaling (MDS) with Rapid Appraisal of Infrastructure (Rapinfra), it uses of Analytic Network Process (ANP) and it uses system dynamics model. The findings of the MDS analysis showed that the status of Bandarlampung City infrastructure sustainability is less sustainable. The ANP analysis produces 8 main indicators of the most influential in the development of sustainable infrastructure. The system dynamics model offered 4 scenarios of sustainable urban infrastructure policy model. The best scenario was implemented into 3 policies consist of: the integrated infrastructure management, the population control, and the local economy development.

    "This article examines polarization reversal in terms of changing human resource profiles related to migration and to national policies affecting the spatial pattern of economic growth. It first demonstrates the relationship between these elements through a review that integrates three distinct themes in earlier research. Attention then turns to an empirical study of human resource variation among eight urban districts and the rest of Venezuela treated as a single unit. This comparison utilizes age, gender, educational attainment, and occupational status variables provided by individual records of Venezuela's 1971 Population Census. A concluding section relates empirical findings to policy alternatives." excerpt

  18. Effect of serial extraction alone on crowding: relationships between tooth width, arch length, and crowding.

    1999-12-01

    In this study, we examined the effect of serial extraction alone on crowding. We also investigated the relationships between tooth width, arch length, and irregularity index. Maxillary dental casts from 32 subjects who had undergone only serial extraction were analyzed at 3 stages: before deciduous canines extraction, after first premolars extraction, and at the end of the observation period. The mean of the irregularity index decreased significantly as serial extraction proceeded and further decreased during the observation period. In cases where the width of the incisor was more than 2 standard deviations above the means for the control subjects, there was a significant correlation between tooth width of the lateral incisors and irregularity index before extraction as well as a significant correlation between the summation of tooth widths of the central and lateral incisors and irregularity index at that time. There was a significant negative correlation between arch length discrepancy and irregularity index before extraction and also a significant correlation between arch length discrepancy and correction of the irregularity index from before deciduous canines extraction to after first premolars extraction. These results suggest that tooth width and arch length discrepancy might preferentially affect the degree of anterior crowding in cases of severe crowding. There was no aggravation of the average crowding level during the observation period in the present study. The present study quantitatively suggested that serial extraction was useful for the purpose of correcting crowding in most cases.

  19. South African serial rapists: the offenders, their victims, and their offenses.

    2012-12-01

    Serial rapists have the propensity to cause harm to a significant number of victims, meaning that they are of concern to the police as well as to treatment providers. Despite the serious nature of their offending, there are surprisingly few studies that provide information regarding their characteristics, the types of victim they target, or the nature of the sexual offenses they commit, and those studies that do exist are varied in their findings. This study provides a descriptive analysis of serial rape in South Africa. One hundred and nineteen sexual offenses committed by 22 serial rapists were sampled. Information regarding the victims, the offenders, and the crimes they had committed were extracted from police files. The characteristics of victims and offenders are reported as well as the frequencies for 114 different crime scene behaviors. When compared with samples of serial sex offenders from other countries, differences emerged in victim characteristics and crime scene behaviors, including how the victims were targeted, the sexual behaviors engaged in, and the incidence of physical violence. The implications of these observed differences for practice are discussed.

MÉTODO: Uma revisão bibliográfica foi feita no sentido de se abordar convergências e divergências entre diversos autores sobre um assunto tão polêmico, sobretudo quanto à viabilidade de tratamento dessa clientela forense. RESULTADOS: Enquanto o transtorno de personalidade anti-social é um diagnóstico médico, pode-se entender o termo "psicopatia", pertencente à esfera psiquiátrico-forense, como um "diagnóstico legal". Não se pode falar ainda de tratamento eficaz para os chamados "serial killers". CONCLUSÃO: Os transtornos de personalidade, especialmente o tipo anti-social, representam ainda hoje um verdadeiro desafio para a psiquiatria forense. O local mais adequado e justo para seus portadores, bem como recomendação homogênea e padronizada de tratamento são questões ainda não respondidas.OBJECTIVE: To illustrate the basic characteristics of several specific personality disorders, focusing mainly in antisocial personality disorder.

    Objectives  To identify the policies of major pharmaceutical companies on transparency of trials, to extract structured data detailing each companies' commitments, and to assess concordance with ethical and professional guidance. Design  Structured audit. Setting  Pharmaceutical companies, worldwide. Participants  42 pharmaceutical companies. Main outcome measures  Companies' commitments on sharing summary results, clinical study reports (CSRs), individual patient data (IPD), and trial registration, for prospective and retrospective trials. Results  Policies were highly variable. Of 23 companies eligible from the top 25 companies by revenue, 21 (91%) committed to register all trials and 22 (96%) committed to share summary results; however, policies commonly lacked timelines for disclosure, and trials on unlicensed medicines and off-label uses were only included in six (26%). 17 companies (74%) committed to share the summary results of past trials. The median start date for this commitment was 2005. 22 companies (96%) had a policy on sharing CSRs, mostly on request: two committed to share only synopses and only two policies included unlicensed treatments. 22 companies (96%) had a policy to share IPD; 14 included phase IV trials (one included trials on unlicensed medicines and off-label uses). Policies in the exploratory group of smaller companies made fewer transparency commitments. Two companies fell short of industry body commitments on registration, three on summary results. Examples of contradictory and ambiguous language were documented and summarised by theme. 23/42 companies (55%) responded to feedback; 7/1806 scored policy elements were revised in light of feedback from companies (0.4%). Several companies committed to changing policy; some made changes immediately. Conclusions  The commitments made by companies to transparency of trials were highly variable. Other than journal submission for all trials within 12 months, all elements of best practice

Methods A convenient sample of 188 members of CPOs participated in the study (95 respondents from 10 CPOs in Italy and 93 from 12 CPOs in France. Participants completed online a self-reported questionnaire, encompassing the 9-item index and questions enquiring about the type and impact of participation in various facets of health policy decisionmaking. The psychometric properties of the scale were explored by performing factor analysis (construct validity and by computing Cronbach α (internal consistency. Results Findings indicate that the index has good internal consistency and the construct it taps is unidimensional. The degree and impact of CPO participation in health policy decision-making were found to be low in both countries; however in Italy they were comparatively lower than in France. Conclusion In conclusion, the HDI can be effectively used in international policy and research contexts. CPOs participation is low in Italy and France and concerted efforts should be made on upgrading their role in health policy decision-making.

    2014-01-01

    Nursing education reform is identified as an important strategy for enhancing health workforce performance, and thereby improving the functioning of health systems. Globally, a predominant trend in such reform is towards greater professionalisation and university-based education. Related nursing education reform in South Africa culminated in a new Framework for Nursing Qualifications in 2013. We undertook a policy analysis study of the development of the new Nursing Qualifications Framework in South Africa. We used a policy analysis framework derived from Walt and Gilson that interrogated the context, content, actors, and processes of policy development and implementation. Following informed consent, in-depth interviews were conducted with 28 key informants from national and provincial government; the South African Nursing Council; the national nursing association; nursing academics, managers, and educators; and other nursing organisations. The interviews were complemented with a review of relevant legislation and policy documents. Documents and interview transcripts were coded thematically using Atlas-ti software. The revision of nursing qualifications was part of the post-apartheid transformation of nursing, but was also influenced by changes in the education sector. The policy process took more than 10 years to complete and the final Regulations were promulgated in 2013. The two most important changes are the requirement for a baccalaureate degree to qualify as a professional nurse and abolishing the enrolled nurse with 2 years training in favour of a staff nurse with a 3-year college diploma. Respondents criticised slow progress, weak governance by the Nursing Council and the Department of Health, limited planning for implementation, and the inappropriateness of the proposals for South Africa. The study found significant weaknesses in the policy capacity of the main institutions responsible for the leadership and governance of nursing in South Africa, which
