  1. DC-9/JT8D refan, Phase 1. [technical and economic feasibility of retrofitting DC-9 aircraft with refan engine to achieve desired acoustic levels

    NASA Technical Reports Server (NTRS)

    1973-01-01

    Analyses and design studies were conducted on the technical and economic feasibility of installing the JT8D-109 refan engine on the DC-9 aircraft. Design criteria included minimum change to the airframe to achieve desired acoustic levels. Several acoustic configurations were studied with two selected for detailed investigations. The minimum selected acoustic treatment configuration results in an estimated aircraft weight increase of 608 kg (1,342 lb) and the maximum selected acoustic treatment configuration results in an estimated aircraft weight increase of 809 kg (1,784 lb). The range loss for the minimum and maximum selected acoustic treatment configurations based on long range cruise at 10 668 m (35,000 ft) altitude with a typical payload of 6 804 kg (15,000 lb) amounts to 54 km (86 n. mi.) respectively. Estimated reduction in EPNL's for minimum selected treatment show 8 EPNdB at approach, 12 EPNdB for takeoff with power cutback, 15 EPNdB for takeoff without power cutback and 12 EPNdB for sideline using FAR Part 36. Little difference was estimated in EPNL between minimum and maximum treatments due to reduced performance of maximum treatment. No major technical problems were encountered in the study. The refan concept for the DC-9 appears technically feasible and economically viable at approximately $1,000,000 per airplane. An additional study of the installation of JT3D-9 refan engine on the DC-8-50/61 and DC-8-62/63 aircraft is included. Three levels of acoustic treatment were suggested for DC-8-50/61 and two levels for DC-8-62/63. Results indicate the DC-8 technically can be retrofitted with refan engines for approximately $2,500,000 per airplane.

    2015-09-01

    Since the introduction of the outcomes-based medical education (OBME) movement, progress toward implementation has been active but challenging. Much of the angst and criticism has been directed at the approaches to assessment that are associated with outcomes-based or competency frameworks, particularly defining the outcomes. In addition, these changes to graduate medical education (GME) are concomitant with major change in health care systems--specifically, changes to increase quality and safety while reducing cost. Every sector, from medical education to health care delivery and financing, is in the midst of substantial change and disruption.The recent release of the Institute of Medicine's report on the financing and governance of GME highlights the urgent need to accelerate the transformation of medical education. One source of continued tension within the medical education community arises from the assumption that the much-needed increases in value and improvement in health care can be achieved by holding the current educational structures and architecture of learning in place while concomitantly withdrawing resources. The authors of this Perspective seek to reframe the important and necessary debate surrounding the current challenges to implementing OBME. Building on recent change and service theories (e.g., Theory U and coproduction), they propose several areas of redirection, including reexamination of curricular models and greater involvement of learners, teachers, and regulators in cocreating new training models, to help facilitate the desired transformation in medical education.

    Social desirability as a tendency to present oneself in a better light rather than in a truthful manner is common feature presented during job interviews. Previous studies mainly focused on blue-collar professions and therefore authors researched contrary set of white-collar professions in three sub-studies with four different participant groups (legal professions; police officers; controls and university students influenced by scenarios; overall N = 636). It was hypothesized that candidates for legal profession would show similar tendency toward social desirability, when compared with controls. Furthermore, police officers were hypothesized to show similar levels of social desirability as legal professions. Lastly, participants in the instruction manipulation condition were hypothesized to show increased levels of social desirability in tender situation as compared to the honest situation. All groups were tested with balanced Inventory of Desirable Responding (BIDR, Paulhus, 1984). Statistical analyses revealed statistically significant differences for both subscales of BIDR when comparing legal professions and control group. Similarly, increased levels of social desirability were detected in police officer candidates as well as in university students in the tender situation compared with students in the honest situation. The overall results indicated that it is typical for white-collar candidates to adapt to the testing situation and it cannot be expected to see different behavior from legal profession candidates as was originally expected.

    Background To investigate alteration of high density lipoproteins (HDL) subclasses distribution in different total cholesterol (TC) levels, mainly the characteristics of HDL subclasses distribution in desirable TC levels and analyze the related mechanisms. Methods ApoA-I contents of plasma HDL subclasses were determined by 2-dimensional gel electrophoresis coupled with immunodetection. 486 Chinese Adults subjects were assigned to different TC groups according to the third Report of NCEP (ATP- III) guidelines. Results The increase in contents of small preβ1-HDL, HDL3c, HDL3b, and HDL3a particles clustered and reduce in HDL2b with increased of TC. The distribution of HDL subclasses have shown abnormality characterized by the lower HDL2b (324.2 mg/L) contents and the higher preβ1-HDL (90.4 mg/L) contents for desirable TC Chinese subjects. Among 176 desirable TC subjects, 58.6% subjects with triglyceride (TG) < 2.26 mmol/L, 61.2% subjects with HDL-C ≥1.03 mmol/L and 88.6% subjects with low density lipoprotein cholesterol(LDL-C) < 3.34 mmol/L, and the profile of HDL subclasses distribution for above these subjects was reasonable. Conclusions The particles size of HDL subclasses shifted towards smaller with increased TC levels. The TC was liner with HDL2b contents and those can be reduced 17 mg/L for 0.5 mmol/L increment in TC levels. The HDL subclasses distribution phenotype was not expectation for Chinese Population with desirable TC levels. Thus, from the HDL subclasses distribution point, when assessing the coronary heart disease(CHD) risk not only rely on the TC levels, but also the concentrations of TG, HDL-C and LDL-C must considered in case the potential risk for desirable TC subjects with other plasma lipids metabolism disorders.

    Hypovitaminosis D is prevalent worldwide but proportions vary widely between regions, depending on genetic and lifestyle factors, the threshold to define deficiency, and accuracy of 25-hydroxyvitamin D (25OHD) assays used. Latitude, pollution, concealing clothing, sun exposure, gender, dietary habits, and lack of government regulation account for up to 50% in variations in serum 25OHD levels, whereas genetic polymorphisms in the vitamin D pathway account for less than 5%. Organizations/societies have developed guidelines for recommended desirable 25OHD levels and vitamin D doses to reach them, but their applicability across age groups and populations are still debated. This article and the accompanying online Supporting Information highlight sources of variations in circulating 25OHD levels, uncertainties and knowledge gaps, and analytical problems facing 25OHD assays, while keeping efficacy and safety data as the dominant factors when defining a desirable range for 25OHD levels. We propose a desirable range of 20 to 40 ng/mL (50 to 100 nmol/L), provided precise and accurate assays are used. Although slightly lower levels, 15 to 20 ng/mL, may be sufficient for some infants and adults, higher levels, 40 to 60 ng/mL, may still be safe. This desirable range allows physicians to tailor treatment while taking season, lifestyle, vitamin D intake, and other sources of variation into account. We reserve 25OHD measurements for at-risk patients, defined by disease or lifestyle, and the use of 25OHD assays calibrated against the recommended international standards. Most target groups reach desirable target levels by a daily intake of 400 to 600 IU for children and 800 IU for adults. A total daily allowance of vitamin D of up to 1000 IU in the pediatric age groups, and up to 2000 IU in adults, tailored to an individual patient risk profile, is probably safe over long durations. Additional data are needed to validate the proposed range and vitamin D doses

    Objectives To investigate DKK-1 and SOST serum levels among patients with recent inflammatory back pain (IBP) fulfilling ASAS criteria for SpA and associated factors. Methods The DESIR cohort is a prospective, multicenter French cohort of 708 patients with early IBP (duration >3 months and <3 years) suggestive of AxSpA. DKK-1 and SOST serum levels were assessed at baseline and were compared between the subgroup of patients fulfilling ASAS criteria for SpA (n = 486; 68.6%) and 80 healthy controls. Results Mean SOST serum levels were lower in ASAS+ patients than healthy controls (49.21 ± 25.9 vs. 87.8 ± 26 pmol/L; p<0.0001). In multivariate analysis, age (p = 5.4 10−9), CRP level (p<0.0001) and serum DKK-1 level (p = 0.001) were associated with SOST level. Mean DKK-1 serum levels were higher in axial SpA patients than controls (30.03 ± 15.5 vs. 11.6 ± 4.2 pmol/L; p<0.0001). In multivariate analysis, DKK-1 serum levels were associated with male gender (p = 0.03), CRP level (p = 0.006), SOST serum level (p = 0.002) and presence of sacroiliitis on radiography (p = 0.05). Genetic association testing of 10 SNPs encompassing the DKK-1 locus failed to demonstrate a significant contribution of genetics to control of DKK-1 serum levels. Conclusions DKK-1 serum levels were increased and SOST levels were decreased among a large cohort of patients with early axial SpA compared to healthy controls. DKK-1 serum levels were mostly associated with biological inflammation and SOST serum levels. PMID:26313358

    Elbert, Chanda Dehron

    The purpose of this study was to identify the competencies needed by secondary agricultural teachers in the Commonwealth of Pennsylvania. Specifically, this study identified competencies needed to help make teachers more effective while working with special needs students. The objectives of the study were to: (1) determine, verify, and evaluate competencies needed by secondary teachers of agriculture to work with handicapped students enrolled in agricultural and vocational education programs; (2) determine, verify, and evaluate competencies needed by secondary teachers of agriculture to work with economically disadvantaged students enrolled in agricultural and vocational education programs; (3) determine, verify, and evaluate competencies needed by secondary teachers of agriculture to work with academically challenged students enrolled in agricultural and vocational programs; and (4) evaluate the self-perceived competency levels of secondary agricultural education teachers and their desired competency levels. A 50% simple random sample of secondary agricultural teachers from the Directory for Agricultural Education in Pennsylvania, 1999--2000 was used. The design for the study was a descriptive study. The data collection instrument used was divided into five different areas: personal characteristics, professional role and development, instructional role, knowledge statements, and student leadership and organization. Subjects were asked to rate their present and desired levels of competency in the categories using a Likert-type scale. The competency scale was as follows: 1 = not competent; 2 = slightly competent, 3 = competent; 4 = very competent; 5 = extremely competent. There were 153 questionnaires mailed to the secondary agricultural education teachers. A total of 96 teachers responded to the questionnaire. Frequencies and distributions were used to describe demographic variables. T-test and analysis of variance were used to determine relationships between

    A discussion of the protocols used particularly in the clinical application of the Desired Sensation Level (DSL) Method is presented in this chapter. In the first section, the measurement and application of acoustic transforms is described in terms of their importance in the assessment phase of the amplification fitting process. Specifically, the implications of individual ear canal acoustics and their impact on accurately defining hearing thresholds are discussed. Detailed information about the statistical strength of the real-ear-to-coupler difference (RECD) measurement and how to obtain the measure in young infants is also provided. In addition, the findings of a study that examined the relationship between behavioral and electrophysiologic thresholds in real-ear SPL is described. The second section presents information related to the electroacoustic verification of hearing instruments. The RECD is discussed in relation to its application in simulated measurements of real-ear hearing instrument performance. In particular, the effects of the transducer and coupling method during the RECD measurement are described in terms of their impact on verification measures. The topics of insertion gain, test signals, and venting are also considered. The third section presents three summary tables that outline the hearing instrument fitting process for infants, children, and adults. Overall, this chapter provides both clinical and scientific information about procedures used in the assessment and verification stages of the DSL Method. PMID:16424946

    This personal commentary explores some issues that arise in the text of the interview with Lord Darzi published in LJPC 6.6, from a point of view of an interest in health policy and change in healthcare organisations. It suggests that the vision is desirable but that there are four major questions about ready implementation that the field needs to consider: 1 Can primary care development and investment be protected in a cold financial climate? 2 Does the current marketisation of health care erode integration? 3 Does the health and social care system in London behave like a real system? 4 Is there really a cultural shift towards empowerment and organisational learning?

    This study was a 12-week double blind placebo-controlled, randomized, parallel trial in which active treatment with different doses of Maca Gelatinizada was compared with placebo. The study aimed to demonstrate if effect of Maca on subjective report of sexual desire was because of effect on mood or serum testosterone levels. Men aged 21-56 years received Maca in one of two doses: 1,500 mg or 3,000 mg or placebo. Self-perception on sexual desire, score for Hamilton test for depression, and Hamilton test for anxiety were measured at 4, 8 and 12 weeks of treatment. An improvement in sexual desire was observed with Maca since 8 weeks of treatment. Serum testosterone and oestradiol levels were not different in men treated with Maca and in those treated with placebo (P:NS). Logistic regression analysis showed that Maca has an independent effect on sexual desire at 8 and 12 weeks of treatment, and this effect is not because of changes in either Hamilton scores for depression or anxiety or serum testosterone and oestradiol levels. In conclusion, treatment with Maca improved sexual desire. PMID:12472620

  19. Maternal obesity and metabolic risk to the offspring: why lifestyle interventions may have not achieved the desired outcomes

    2015-01-01

    Obesity during pregnancy is associated with an increased risk of short- and long-term metabolic dysfunction in the mother and her offspring. Both higher maternal pregravid body mass index (kg m−2) and excessive gestational weight gain (GWG) have been associated with adverse pregnancy outcomes such as gestational diabetes, preeclampsia and fetal adiposity. Multiple lifestyle intervention trials consisting of weight management using various diets, increased physical activity and behavioral modification techniques have been employed to avoid excessive GWG and improve perinatal outcomes. These randomized controlled trials (RCTs) have achieved modest success in decreasing excessive GWG, although the decrease in GWG was often not within the current Institute of Medicine guidelines. RCTs have generally not had any success with decreasing the risk of maternal gestational diabetes (GDM), preeclampsia or excessive fetal growth often referred to as macrosomia. Although the lack of success for these trials has been attributed to lack of statistical power and poor compliance with study protocols, our own research suggests that maternal pregravid and early pregnancy metabolic condition programs early placenta function and gene expression. These alterations in maternal/placental function occur in the first trimester of pregnancy prior to when most intervention trials are initiated. For example, maternal accrural of adipose tissue relies on prior activation of genes controlling lipogenesis and low-grade inflammation in early pregnancy. These metabolic alterations occur prior to any changes in maternal phenotype. Therefore, trials of lifestyle interventions before pregnancy are needed to demonstrate the safety and efficacy for both the mother and her offspring. PMID:25777180

    2014-01-01

    We (Kranzler et al. 2014) reported that topiramate 200 mg/day reduced heavy drinking days and increased abstinent days in 138 heavy drinkers whose treatment goal was to reduce drinking to safe levels. In that 12-week, placebo-controlled study, we measured drinking using the Timeline Follow-back method at each treatment visit. In addition to the intent-to-treat effects of topiramate, we found that a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the GluK1 subunit of the kainate receptor, moderated the treatment effect in European Americans (EAs; n=122). Topiramate reduced heavy drinking only in rs2832407*C allele homozygotes. Here, we augment those analyses by using patients’ daily reports obtained using interactive voice response technology (a) to validate the interactive effects of GRIK1 and topiramate as predictors of drinking level and (b) to examine changes in expected positive effects of drinking (i.e., positive outcome expectancies) and desire to drink. We found that rs2832407*C allele homozygotes treated with topiramate drank less overall during treatment than those receiving placebo, validating our earlier findings for heavy drinking days (Kranzler et al. 2014). There was also a study day × medication group × genotype group interaction that predicted both positive alcohol expectancies and desire to drink, with rs2832407*C-allele homozygotes treated with topiramate showing the largest decreases in these outcomes during the study period. Changes in positive alcohol expectancies or desire to drink did not mediate the effects on drinking. These findings validate and extend our previous pharmacogenetic findings with topiramate.

    Arachidonic (ARA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids are the most biologically active polyunsaturated fatty acids, but their biosyntheses in mammals are very limited. The biosynthesis of DHA is the most difficult, because this undergoes the Sprecher pathway–a further elongation step from docosapentaenoic acid (DPA), a Δ6-desaturase acting on a C24 fatty acid substrate followed by a peroxisomal chain shortening step. This paper reports the successful heterologous expression of two non-mammalian genes (with modification of codon usage), coding for Euglena gracilis Δ4-desaturase and Siganus canaliculatus Δ4-desaturase respectively, in mammalian cells (HEK293 cell line). Both of the Δ4-desaturases can efficiently function, directly converting DPA into DHA. Moreover, the cooperation of the E. gracilis Δ4-desaturase with C. elegans Δ15-desaturase (able to convert a number of n-6 PUFAs to their corresponding n-3 PUFAs) in transgenic HEK293 cells made a more desirable fatty acid composition – a drastically reduced n-6/n-3 PUFAs ratio and a high level of DHA as well as EPA and ARA. Our findings provide a basis for potential applications of the gene constructs for expression of Δ15/Δ4-desaturases in transgenic livestock to produce such a fatty acid profile in the related products, which certainly will bring benefit to human health.

    Full network level privacy has often been categorized into four sub-categories: Identity, Route, Location and Data privacy. Achieving full network level privacy is a critical and challenging problem due to the constraints imposed by the sensor nodes (e.g., energy, memory and computation power), sensor networks (e.g., mobility and topology) and QoS issues (e.g., packet reach-ability and timeliness). In this paper, we proposed two new identity, route and location privacy algorithms and data privacy mechanism that addresses this problem. The proposed solutions provide additional trustworthiness and reliability at modest cost of memory and energy. Also, we proved that our proposed solutions provide protection against various privacy disclosure attacks, such as eavesdropping and hop-by-hop trace back attacks. PMID:22294881

    2013-01-01

    Microbial enzymes have been used in a large number of fields, such as chemical, agricultural and biopharmaceutical industries. The enzyme production rate and yield are the main factors to consider when choosing the appropriate expression system for the production of recombinant proteins. Recombinant enzymes have been expressed in bacteria (e.g., Escherichia coli, Bacillus and lactic acid bacteria), filamentous fungi (e.g., Aspergillus) and yeasts (e.g., Pichia pastoris). The favorable and very advantageous characteristics of these species have resulted in an increasing number of biotechnological applications. Bacterial hosts (e.g., E. coli) can be used to quickly and easily overexpress recombinant enzymes; however, bacterial systems cannot express very large proteins and proteins that require post-translational modifications. The main bacterial expression hosts, with the exception of lactic acid bacteria and filamentous fungi, can produce several toxins which are not compatible with the expression of recombinant enzymes in food and drugs. However, due to the multiplicity of the physiological impacts arising from high-level expression of genes encoding the enzymes and expression hosts, the goal of overproduction can hardly be achieved, and therefore, the yield of recombinant enzymes is limited. In this review, the recent strategies used for the high-level expression of microbial enzymes in the hosts mentioned above are summarized and the prospects are also discussed. We hope this review will contribute to the development of the enzyme-related research field. PMID:23686280

    An understanding of wildness is being developed as a quality of interactive processing that increases survival opportunities in nature. A link is made between the need to improve interactive quality for wildness, and cognitive desires and interests in art, music, religion and philosophy as these can also be seen as attempts to improve interactive quality internally and externally. Interactive quality can be improved through gains in parsimony, that is, simplifications in the organisation of skills. The importance of parsimony in evolution is discussed, along with indicators of an internal parsimony desire that experiences joy if achieved through processes such as insight and understanding. A mechanism for the production and measurement of the parsimony desire is proposed, based on the number of subcortical pleasure hotspots that can be stimulated at once within the ‘archipelago’ available in the limbic system.

    Measures are needed to assess youth perceptions about health science careers to facilitate research aimed at facilitating youth pursuit of health science. Although the Indiana Instrument provides an established measure of perceptions regarding nursing and ideal careers, we were interested in learning how high achieving 10th graders from relatively low socioeconomic areas who identify as Black/African American (Black) perceive health science and ideal careers. The Indiana Instrument was modified, administered to 90 youth of interest, and psychometrically analyzed. Reliable subscales were identified that may facilitate parsimonious, theoretical, and reliable study of youth decision-making regarding health science careers. Such research may help to develop and evaluate strategies for increasing the number of minority health scientists. PMID:25194058

    Several studies have shown that a woman’s vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on pads affixed to the axilla and on panty protectors both worn the entire night before experiments. Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60, and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol. Periovulatory axilla and vulva scents accounted for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant. PMID:24194730

    We used the World Health Organization's recommended procedures to establish desirable fortificant levels for three problem micronutrients in children's diets, based on dietary data collected earlier from Filipino (n = 1374; 6-36 months), Mongolian (n = 179; 12-36 months) and Cambodian (n = 177; 12-36 months) children. Prevalence of inadequate and excessive intakes of calcium and zinc (via cut-point method) and iron (via full-probability approach) was assessed after adjusting usual intake distributions with pc-side using internal or external within-person variances from Filipino (calcium and iron) and US National Health And Nutrition Examination Survey III (zinc) national surveys. Fortificant levels were determined by repositioning usual intake distributions so that the 2.5th percentile of the targeted populations equalled the estimated average requirement (calcium, zinc) or so that full-probability prevalence was no larger than 2.5% (iron). Prevalence of inadequate intakes was ≥70% for calcium and iron, except Filipino infants (30% for Ca) and Cambodian toddlers (41% for Fe); but <1% for zinc for toddlers in Mongolia and 20% in Cambodia. Prevalence of excessive intakes was <1% for zinc, calcium and iron, except for Mongolian toddlers (11% for Zn). Desirable fortificant levels, although apparently negligible for zinc, were 530-783 mg for calcium and 10.8-22.8 mg for iron (per 100 g). Fortificant levels can be estimated from 24-h recalls, preferably by applying internal within-person variances. Fortification with calcium and iron was necessary, but seemingly not for zinc, despite a high prevalence of low serum zinc, suggesting the need for better defined cut-offs for population risk of zinc deficiency based on dietary zinc intake and/or serum zinc.

    2008-01-01

    In an event-related fMRI study, we scanned eighteen normal human subjects while they viewed three categories of pictures (events, objects and persons) which they classified according to desirability (desirable, indifferent or undesirable). Each category produced activity in a distinct part of the visual brain, thus reflecting its functional specialization. We used conjunction analysis to learn whether there is a brain area which is always active when a desirable picture is viewed, regardless of the category to which it belongs. The conjunction analysis of the contrast desirable > undesirable revealed activity in the superior orbito-frontal cortex. This activity bore a positive linear relationship to the declared level of desirability. The conjunction analysis of desirable > indifferent revealed activity in the mid-cingulate cortex and in the anterior cingulate cortex. In the former, activity was greater for desirable and undesirable stimuli than for stimuli classed as indifferent. Other conjunction analyses produced no significant effects. These results show that categorizing any stimulus according to its desirability activates three different brain areas: the superior orbito-frontal, the mid-cingulate, and the anterior cingulate cortices.

    Cuccio Schirripa, Santine

    The effects of instruction in writing researchable questions, science topic interest, and achievement (science, reading, and mathematics) on science question level in seventh grade students were investigated experimentally. The hypotheses were: students instructed in researchable questioning in science would outperform students who were not instructed on a measure of science question level; students interested in science topics would score higher on a measure of science question level, than when they are not interested; and high achieving students in mathematics, reading or science would outperform students who are not high achievers on a measure of science question level. Eight classes of normally achieving seventh graders (n = 106 students), from a middle school in west central Florida, were randomly assigned to two treatments. One group received instruction in writing researchable questions in science, the other group did not receive instruction. Each student in each of the eight classes completed "The Middle School Students' Science Topic Interest Rating Scale", developed for this study (test-retest reliability, rsbs =.84), rating each of the thirteen topics from one to three. All students selected two topics in which they were least interested, and two topics in which they were most interested. They then wrote researchable questions for each topic. All students took the Scholastic Aptitude Tests (SAT) in reading, mathematics and science. The questions were rated using the four levels described by "The Middle School Students' Science Question Rating Scale", developed for this study (inter-rater reliability, rsbs =.96). The scores for each question were averaged for two raters then summed for each interest level for each student The means and standard deviations were computed for questions generated at a low level of interest, questions generated at a high level of interest, reading SAT scores, mathematics SAT scores, and science SAT scores.

    Lin, Shu-Fen; Lin, Huann-shyang

    2016-05-01

    Comics are popular with adolescents because of their features of humor, narrative, and visual imagery. The purposes of this study were to examine the learning outcomes and emotional perceptions of reading a science comic book and a science text booklet for students of different levels of achievement, and to explore the main factors of the two media which attract high-school students to learn science. A mixed-method quasi-experimental design was adopted. The participants were 697 grade ten students from eight schools with different levels of academic achievement. Two similar classes in each of the eight schools were assigned as the comic group or the text group. The results indicated that the science comic book benefited medium achievers more than the science text booklet did, but the contrary result was found for the high achievers. In comparison, the two media benefited the low achievers equally, but both had only a limited effect due to the students' lack of prior knowledge. We conclude four kinds of evidence, including perceived difficulty of comprehension, reasons for interest/disinterest, emotional perceptions of learning science, and learning time, to support the phenomenon of the learning benefit of media specific to certain achievers' science learning.

  12. The effects of student-level and classroom-level factors on elementary students' science achievement in five countries

    NASA Astrophysics Data System (ADS)

    Kaya, Sibel

    The interest in raising levels of achievement in math and science has led to a focus on investigating the factors that shape achievement in these subjects (Lamb & Fullarton, 2002) as well as understanding how these factors operate across countries (Baker, Fabrega, Galindo, & Mishook, 2004). The current study examined the individual student factors and classroom factors on fourth grade science achievement within and across five countries. Guided by the previous school learning models, the elements of students' science learning were categorized as student-level and classroom-level factors. The student-level factors included gender, self-confidence in science, and home resources. The classroom-level factors included teacher characteristics, instructional variables and classroom composition. Results for the United States and four other countries, Singapore, Japan, Australia, and Scotland were reported. Multilevel effects of student and classroom variables were examined through Hierarchical Linear Modeling (HLM) using the Trends in International Mathematics and Science Study (TIMSS) 2003 fourth grade dataset. The outcome variable was the TIMSS 2003 science score. Overall, the results of this study showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student-level, higher levels of home resources and self-confidence and at the classroom-level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the U.S. and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the U.S. and Australia. Experimental studies that investigate the impacts of teacher and instructional factors on elementary science achievement are

    Although many studies have examined associations between family structure and children’s educational achievement at the individual level, few studies have considered how the increase in single-parent households may have affected children’s educational achievement at the population level. We examined changes in the percentage of children living with single parents between 1990 and 2011 and state mathematics and reading scores on the National Assessment of Educational Progress. Regression models with state and year fixed effects revealed that changes in the percentage of children living with single parents were not associated with test scores. Increases in maternal education, however, were associated with improvements in children’s test scores during this period. These results do not support the notion that increases in single parenthood have had serious consequences for U.S. children’s school achievement. PMID:26188447

  15. Fraction of the theoretical specific energy achieved on pack level for hypothetical battery chemistries

    In valuing new active materials chemistries for advanced batteries, the theoretical specific energy is commonly used to motivate research and development. A packaging factor is then used to relate the theoretical specific energy to the pack-level specific energy. As this factor is typically assumed constant, higher theoretical specific energies are judged to result in higher pack-level specific energies. To test this implicit assumption, we calculated the fraction of the theoretical specific energy achieved on the pack level for hypothetical cell chemistries with various open-circuit voltages and theoretical specific energies using a peer-review bottom-up battery design model. The pack-level specific energy shows significant dependence on the open-circuit voltage and electrochemical impedance due to changes in the quantity of inactive materials required. At low-valued average open-circuit voltages, systems with dramatically different theoretical specific energies may result in battery packs similar in mass and volume. The fraction of the theoretical specific energy achieved on the pack level is higher for the lower theoretical specific energy systems mainly because the active materials mass dominates the pack mass. Finally, low-valued area-specific impedance is shown to be critical for chemistries of high theoretical specific energy and low open-circuit voltage to achieve higher pack-level specific energies.

    2008-01-01

    Hypoactive sexual desire disorder (HSDD) and sexual aversion disorder (SAD) are an under-diagnosed group of disorders that affect men and women. Despite their prevalence, these two disorders are often not addressed by healthcare providers and patients due their private and awkward nature. As physicians, we need to move beyond our own unease in order to adequately address our patients’ sexual problems and implement appropriate treatment. Using the Sexual Response Cycle as the model of the physiological changes of humans during sexual stimulation and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition this article will review the current literature on the desire disorders focusing on prevalence, etiology, and treatment.

    PubMed

    Smith, L R; Ryan, B E

    1997-01-01

    The joint effects of student achievement level and attitude survey format upon attitudes toward reading were investigated. Sixth-grade students completed reading attitude surveys involving a standard Likert-type format or one involving pictures of the comic strip character, Garfield. The survey items were identical for both formats; only the presentation format was varied. There was no significant main effect on attitude responses due to achievement level, but the main effect due to survey format was significant, with the Likert-type format producing significantly higher attitude responses than the Garfield format. The interaction between achievement level and format also was significant, with above average students and average students giving higher attitude responses than did below average students when the Garfield format was used. When the Likert-type format was used, average students and below average students gave higher attitude responses than did above average students. The results imply that attitude responses of adolescents can be manipulated by varying the format of the survey. PMID:9179323

    2015-01-01

    The ability to prepare single-crystal faces has become central to developing and testing models for chemistry at interfaces, spectacularly demonstrated by heterogeneous catalysis and nanoscience. This ability has been hampered for hexagonal ice, Ih––a fundamental hydrogen-bonded surface––due to two characteristics of ice: ice does not readily cleave along a crystal lattice plane and properties of ice grown on a substrate can differ significantly from those of neat ice. This work describes laboratory-based methods both to determine the Ih crystal lattice orientation relative to a surface and to use that orientation to prepare any desired face. The work builds on previous results attaining nearly 100% yield of high-quality, single-crystal boules. With these methods, researchers can prepare authentic, single-crystal ice surfaces for numerous studies including uptake measurements, surface reactivity, and catalytic activity of this ubiquitous, fundamental solid.

    1994-03-01

    A patient with severe tetanus, who had a sympathetic crisis while sedated with 30 mg/h diazepam and 30 mg/h morphine, is described. Satisfactory control of the haemodynamic crisis was achieved with bolus doses of esmolol to a total of 180 mg. A disturbing finding was that although there was adequate control of the tachycardia and hypertension, arterial catecholamine levels remained markedly elevated. Adrenaline levels of 531 pg/ml (normal 10-110 pg/ml) and noradrenaline levels of 1,036 pg/ml (normal 100-500 pg/ml) were recorded when the patient had a systolic arterial pressure of 110 mmHg and a heart rate of 97/min. The implications of this finding are discussed. PMID:11218441

    2013-01-01

    Background/Context Efforts to improve student achievement should increase graduation rates. However, work investigating the effects of student-level accountability has consistently demonstrated that increases in the standards for high school graduation are correlated with increases in dropout rates. The most favored explanation for this finding is that high-stakes testing policies that mandate grade repetition and high school exit exams may be the tipping point for students who are already struggling academically. These extra demands may, in fact, push students out of school. Purpose/Objective/Focus This article examines two hypotheses regarding the relation between school-level accountability and dropout rates. The first posits that improvements in school performance lead to improved success for everyone. If school-level accountability systems improve a school for all students, then the proportion of students performing at grade level increases, and the dropout rate decreases. The second hypothesis posits that schools facing pressure to improve their overall accountability score may pursue this increase at the cost of other student outcomes, including dropout rate. Research Design Our approach focuses on the dynamic relation between school-level academic achievement and dropout rates over time—that is, between one year’s achievement and the subsequent year’s dropout rate, and vice versa. This article employs longitudinal data of records on all students in North Carolina public schools over an 8-year period. Analyses employ fixed-effects models clustering schools and districts within years and controls each year for school size, percentage of students who were free/reduced-price lunch eligible, percentage of students who are ethnic minorities, and locale. Findings/Results This study finds partial evidence that improvements in school-level academic performance will lead to improvements (i.e., decreases) in school-level dropout rates.

    2012-05-15

    Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes were evaluated for their ability to achieve the world's most stringent Hg discharge criterion (<1.3 ng/L) in an oil refinery's wastewater. The membrane processes were operated at three different pressures to demonstrate the potential for each membrane technology to achieve the targeted effluent mercury concentrations. The presence of mercury in the particulate form in the refinery wastewater makes the use of MF and UF membrane technologies more attractive in achieving very low mercury levels in the treated wastewater. Both NF and RO were also able to meet the target mercury concentration at lower operating pressures (20.7 bar). However, higher operating pressures ({ge}34.5 bar) had a significant effect on NF and RO flux and fouling rates, as well as on permeate quality. SEM images of the membranes showed that pore blockage and narrowing were the dominant fouling mechanisms for the MF membrane while surface coverage was the dominant fouling mechanism for the other membranes. The correlation between mercury concentration and particle size distribution was also investigated to understand mercury removal mechanisms by membrane filtration. The mean particle diameter decreased with filtration from 1.1 {+-} 0.0 {micro}m to 0.74 {+-} 0.2 {micro}m after UF.

    The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in Cold Climates on a cost-neutral basis.

    Dostal, Jay Roland

    This study will evaluate alternative scheduling methods implemented in secondary level schools. Students were selected based on parent selection of programs. Traditional scheduling involves numerous academic subjects with small increments of time in each class and block scheduling focuses on fewer academic subjects and more instructional time. This study will compare office referral numbers, absence frequency, and Essential Learner Outcome (ELO) science strand scores in the 8th-grade (pretest) to the same students office referrals, absence frequency, and ELO science strand scores in the 11th-grade (posttest) between Seven Period Traditional Scheduling (SPTS) and Four Period Block Scheduling (FPBS) in the hopes that no matter what schedule students are a part of, the achievement results will be similar. (Study participants had completed both grade level ELO assessments and were continuously enrolled in one high school through their junior year.

  12. Predictors of gender achievement in physical science at the secondary level

    NASA Astrophysics Data System (ADS)

    Kozlenko, Brittany Hunter

    This study used the 2009 National Assessment of Educational Progress (NAEP) science restricted data-set for twelfth graders. The NAEP data used in this research study is derived from a sample group of 11,100 twelfth grade students that represented a national population of over 3,000,000 twelfth grade students enrolled in science in the United States in 2009. The researcher chose the NAEP data set because it provided a national sample using uniform questions. This study investigated how the factors of socioeconomic status (SES), parental education level, mode of instruction, and affective disposition affect twelfth grade students' physical science achievement levels in school for the sample population and subgroups for gender. The factors mode of instruction and affective disposition were built through factor analysis based on available questions from the student surveys. All four factors were found to be significant predictors of physical science achievement for the sample population. NAEP exams are administered to a national sample that represents the population of American students enrolled in public and private schools. This was a non-experimental study that adds to the literature on factors that impact physical science for both genders. A gender gap is essentially nonexistent at the fourth grade level but appears at the eighth grade level in science based on information from NAEP (NCES, 1997). The results of the study can be used to make recommendation for policy change to diminish this gender gap in the future. Educators need to be using research to make instructional decisions; research-based instruction helps all students.

  13. Strategies for achieving high-level expression of genes in Escherichia coli.

    PubMed Central

    Makrides, S C

    1996-01-01

    Progress in our understanding of several biological processes promises to broaden the usefulness of Escherichia coli as a tool for gene expression. There is an expanding choice of tightly regulated prokaryotic promoters suitable for achieving high-level gene expression. New host strains facilitate the formation of disulfide bonds in the reducing environment of the cytoplasm and offer higher protein yields by minimizing proteolytic degradation. Insights into the process of protein translocation across the bacterial membranes may eventually make it possible to achieve robust secretion of specific proteins into the culture medium. Studies involving molecular chaperones have shown that in specific cases, chaperones can be very effective for improved protein folding, solubility, and membrane transport. Negative results derived from such studies are also instructive in formulating different strategies. The remarkable increase in the availability of fusion partners offers a wide range of tools for improved protein folding, solubility, protection from proteases, yield, and secretion into the culture medium, as well as for detection and purification of recombinant proteins. Codon usage is known to present a potential impediment to high-level gene expression in E. coli. Although we still do not understand all the rules governing this phenomenon, it is apparent that "rare" codons, depending on their frequency and context, can have an adverse effect on protein levels. Usually, this problem can be alleviated by modification of the relevant codons or by coexpression of the cognate tRNA genes. Finally, the elucidation of specific determinants of protein degradation, a plethora of protease-deficient host strains, and methods to stabilize proteins afford new strategies to minimize proteolytic susceptibility of recombinant proteins in E. coli.

  16. Leveraging People-Related Maturity Issues for Achieving Higher Maturity and Capability Levels

    NASA Astrophysics Data System (ADS)

    Buglione, Luigi

    During the past 20 years Maturity Models (MM) become a buzzword in the ICT world. Since the initial Crosby's idea in 1979, plenty of models have been created in the Software & Systems Engineering domains, addressing various perspectives. By analyzing the content of the Process Reference Models (PRM) in many of them, it can be noticed that people-related issues have little weight in the appraisals of the capabilities of organizations while in practice they are considered as significant contributors in traditional process and organizational performance appraisals, as stressed instead in well-known Performance Management models such as MBQA, EFQM and BSC. This paper proposes some ways for leveraging people-related maturity issues merging HR practices from several types of maturity models into the organizational Business Process Model (BPM) in order to achieve higher organizational maturity and capability levels.

    The objective of this study was to examine state-level variations in income-related inequality in health and overall health achievement in the US. Data that were representative of the US and each state in 2001 were extracted from the Current Population Survey 2001. Income-related inequality in health and health achievement were measured by Health Concentration and Health Achievement Indices, respectively. Significant variations were found across states in income-related inequality in health and health achievement. In particular, states in the south and east regions, on average, experienced a higher degree of health inequality and lower health achievement. About 80% of the state-level variation in health achievement could be explained by demographics, economic structure and performance, and state and local government spending and burden. In contrast, medical care resource indicators were not found to contribute to health achievement in states. States with better health achievement were more urbanized, had lower proportions of minority groups, females and the elderly, fewer individuals below the poverty line, larger primary industry, and lower unemployment rates. Also, per capita state and local government spending, particularly the proportion spent on public health, was positively associated with better health achievement. Because of the direct implications of health level and distribution in resource allocation and social norms, states with a lower level of health achievement need to prioritize efforts in increasing and reallocating resources to diminish health inequality and to improve population health.

    Introduction: Many studies have investigated the relationship between motivation and educational outcomes. The present study was conducted to determine whether the students’ motivation in Shiraz University of Medical Sciences (SUMS) decreases during educational years. Methods: 770 students in SUMS were selected by multi-stage stratified random sampling from each field and entrance year. The first questionnaire contained 57 questions on the effect of economic, social, educational, geographical and personality factors on the students’ motivation. The second one was based on 50 incomplete sentences. The validity and reliability of these questionnaires were approved by the experts and Cronbach's Alpha coefficients (85% and 90%, respectively). In this cross-sectional study, ANOVA, t-test and Chi-square tests were applied for data analysis at the 0.05 significance level. Results: Six factors with the most effect on academic motivation were "family attitudes", "getting good jobs in future", "respect for themselves", " the ability to learn", "believing their role in victory and defeat" and "the tendency toward optimism about themselves". In addition, comparing professional doctorate and basic sciences’ results revealed no significant relationship between academic motivation and educational years (F=0.819, p=0.397). But comparing field by field showed that Dentistry and Hospital Management and Medical Information (HMMI) had a significant decrease in motivation score by increase in educational years (F=3.991, p=0.015). Conclusion: Achievement motivation level in SUMS students was higher than average and did not decrease during educational years. Also, the results showed that personal, social and educational related factors affected motivation level more than economic and environmental factors. PMID:25587552

  1. Achieving Population-Level Immunity to Rabies in Free-Roaming Dogs in Africa and Asia

    Canine rabies can be effectively controlled by vaccination with readily available, high-quality vaccines. These vaccines should provide protection from challenge in healthy dogs, for the claimed period, for duration of immunity, which is often two or three years. It has been suggested that, in free-roaming dog populations where rabies is endemic, vaccine-induced protection may be compromised by immuno-suppression through malnutrition, infection and other stressors. This may reduce the proportion of dogs that seroconvert to the vaccine during vaccination campaigns and the duration of immunity of those dogs that seroconvert. Vaccination coverage may also be limited through insufficient vaccine delivery during vaccination campaigns and the loss of vaccinated individuals from populations through demographic processes. This is the first longitudinal study to evaluate temporal variations in rabies vaccine-induced serological responses, and factors associated with these variations, at the individual level in previously unvaccinated free-roaming dog populations. Individual-level serological and health-based data were collected from three cohorts of dogs in regions where rabies is endemic, one in South Africa and two in Indonesia. We found that the vast majority of dogs seroconverted to the vaccine; however, there was considerable variation in titres, partly attributable to illness and lactation at the time of vaccination. Furthermore, >70% of the dogs were vaccinated through community engagement and door-to-door vaccine delivery, even in Indonesia where the majority of the dogs needed to be caught by net on successive occasions for repeat blood sampling and vaccination. This demonstrates the feasibility of achieving population-level immunity in free-roaming dog populations in rabies-endemic regions. However, attrition of immune individuals through demographic processes and waning immunity necessitates repeat vaccination of populations within at least two years to ensure

  4. Mice and rats achieve similar levels of performance in an adaptive decision-making task

    2014-01-01

    Two opposing constraints exist when choosing a model organism for studying the neural basis of adaptive decision-making: (1) experimental access and (2) behavioral complexity. Available molecular and genetic approaches for studying neural circuits in the mouse fulfill the first requirement. In contrast, it is still under debate if mice can perform cognitive tasks of sufficient complexity. Here we compare learning and performance of mice and rats, the preferred behavioral rodent model, during an acoustic flexible categorization two-alternative choice task. The task required animals to switch between two categorization definitions several times within a behavioral session. We found that both species achieved similarly high performance levels. On average, rats learned the task faster than mice, although some mice were as fast as the average rat. No major differences in subjective categorization boundaries or the speed of adaptation between the two species were found. Our results demonstrate that mice are an appropriate model for the study of the neural mechanisms underlying adaptive decision-making, and suggest they might be suitable for other cognitive tasks as well.

    The ability to map between non-symbolic and symbolic magnitude representations is crucial in the development of mathematics and this map is disturbed in children with math difficulties. In addition, positive parietal ERPs have been found to be sensitive to the number distance effect and skills solving arithmetic problems. Therefore we aimed to contrast the behavioral and ERP responses in children with different levels of mathematical achievement: low (LA), average (AA) and high (HA), while comparing symbolic and non-symbolic magnitudes. The results showed that LA children repeatedly failed when comparing magnitudes, particularly the symbolic ones. In addition, a positive correlation between correct responses while analyzing symbolic quantities and WRAT-4 scores emerged. The amplitude of N200 was significantly larger during non-symbolic comparisons. In addition, P2P amplitude was consistently smaller in LA children while comparing both symbolic and non-symbolic quantities, and correlated positively with the WRAT-4 scores. The latency of P3 seemed to be sensitive to the type of numerical comparison. The results suggest that math difficulties might be related to a more general magnitude representation problem, and that ERP are useful to study its timecourse in children with different mathematical skills.

  6. [Pregnancy desired--baby refused (author's transl)].

    PubMed

    Olivier, C

    1983-05-01

    This essay seeks to answer the question of why so many abortions are requested in France when contraceptive methods are readily available by arguing that in such cases, the pregnancy is a response to a woman's unconscious desires while the abortion signifies a return to conscious control. The woman's early relationship to her mother is viewed as a factor in the later playing out of unconscious desires. Little girls, by virtue of their similarity to their mothers, can never be sexual objects in the same way that little boys are. Because infant girls are cared for by adult women who are loving, but not desiring, they are less likely to be satisfied in their early feeding, and this insatisfaction is transferred into adult insatiability in terms of all that comes to her from the man, including sperm. Women must wait until their sex lives begin to receive what men have from the moment of birth; a gift from outside themselves, colored by desire. This feeling of completion is however not accompanied by a desire to mother the child. In other cases the pregnancy may be desired as a proof of femininity or of a feeling of equality with other women that may have been poorly established if the identification with the mother functioned badly. The infant represents something more than himself: perhaps the identity of the woman. The multiplicity of factors involved create difficult consultations for the woman and for the doctor, because, in fact, the woman seeking an abortion views the infant as imaginary, not real. A woman who presents herself more often for abortion than for obstetric care is dominated by neurotic unconscious desires. The psychologist can aid the woman in overcoming postabortal depression by helping her achieve a more profound understanding of her unconscious desires. PMID:12338682

    Aikman, K G; Belter, R W; Finch, A J

    1992-01-01

    In a sample of 216 child and adolescent psychiatric inpatients, significant but low correlations were found between Goodenough-Harris (GH) drawing scores and both Full Scale IQs and academic achievement. The percentage of subjects correctly classified in appropriate IQ categories ranged from 35 to 44%; the percentage of misclassified subjects ranged from 56 to 65%. Consideration of visual-motor integration, using the Bender-Gestalt, did not improve the accuracy of G-H scores in predicting IQ scores in this sample. These results indicate that human figure drawings should not be substituted for other well-established intelligence and achievement tests nor used as an additional measure of these constructs when one is evaluating psychiatric patients.

This analysis examines norms about desired family size for 1,366 males and 1,367 females aged 15-24 in 2004 in rural Minya governorate. Two-level random-effects multivariate logistic regression models, stratified by sex and grouped by neighborhood, are used to assess normative influence at the household and neighborhood levels, controlling for individual- and household-level covariates. In the final model, young males in neighborhoods where more people desire a small family are 33 percent more likely to desire a small family than are young males in other neighborhoods. Young females in households with one or more adults preferring a small family are 78 percent more likely to desire a small family, and young females in households with one or more young people who prefer a small family are 37 percent more likely to desire a small family themselves, compared with those living with adults or with young people, respectively, who do not prefer a small family. Programs aiming to reduce fertility should be aware of gender differences in the sources of normative influence on desired family size. PMID:21834412

  4. Achieving Sub-Design Level Contrast for Coronagraphs with Deformable Mirrors

    NASA Astrophysics Data System (ADS)

    Eldorado Riggs, A. J.; Groff, T. D.; Carlotti, A.; Kasdin, N. J.

    2013-01-01

    Coronagraphs for space-based detection of earth-like exoplanets are normally designed assuming perfect optics. One or more deformable mirrors (DMs) are then utilized to correct for these aberrations and recover the lost contrast. We demonstrate a new, unified approach in which the coronagraph needs a design contrast only on the order of the errors in the optics. The DMs can then be used to achieve higher contrast by treating small areas of the coronagraph as amplitude errors in the system. This approach eases design and manufacturing constraints on coronagraphs and yields higher throughput designs. Our initial simulations show that a single DM conjugate to a shaped pupil coronagraph can achieve a single-sided dark hole higher in contrast than the shaped pupil is designed for. Future work will focus on simulating double-sided dark holes with two DMs non-conjugate to the pupil plane. This will enable experiments performed in the Princeton High Contrast Imaging (HCIL) Lab with our two Boston Micromachines Corp. kilo-DMs. Symmetric dark holes have already been generated at the HCIL using the Stroke Minimization algorithm and a high contrast shaped pupil in monochromatic and broadband light. Experiments with the unified shaped pupil-DM system will utilize the Kalman filter estimator recently developed in the HCIL for focal plane wavefront correction.

    2016-01-01

    Context: Relatively few patients with gout receive appropriate treatment. Objective: To determine whether a pharmacist-staffed gout management program is more effective than usual care in achieving target serum uric acid (sUA) levels in gout patients. Design: A parallel-group, randomized controlled trial of a pharmacist-staffed, telephone-based program for managing hyperuricemia vs usual care. Trial duration was 26 weeks. Main Outcome Measures: Primary outcome measure was achieving sUA levels at or below 6 mg/dL at the 26-week visit. Secondary outcome was mean change in sUA levels in the control and intervention groups. Participants were adults with recurrent gout and sUA levels above 6.0 mg/dL. Participants were randomly assigned to management by a clinical pharmacist following protocol or to monitoring of sUA levels but management of their gout by their usual treating physician. Results: Of 102 patients who met eligibility criteria, 77 subjects obtained a baseline sUA measurement and were entered into the trial. Among 37 participants in the intervention group, 13 (35%) had sUA levels at or below 6.0 mg/dL at 26 weeks, compared with 5 (13%) of 40 participants in the control group (risk ratio = 2.8, 95% confidence interval [CI] = 1.1 to 7.1, p = 0.03). The mean change in sUA levels among controls was +0.1 mg/dL compared with −1.5 mg/dL in the intervention group (sUA difference = −1.6, 95% CI = −0.9 to −2.4, p < 0.001). Conclusions: A structured pharmacist-staffed program was more effective than usual care for achieving target sUA levels. These results suggest a structured program could greatly improve gout management. PMID:27352414

  15. Charter school education in Texas: Student achievement on the exit level assessment in math and science

    NASA Astrophysics Data System (ADS)

    Turner, Jeffery E.

    Public schools in the state of Texas are held accountable for performance and quality of education. Accountability is important to all schools, but it is critical to open-enrollment charter schools to remain in good standing. The current economic situation in Texas public education has brought attention as well as the need for alternative education programs such as charter schools. It is of the utmost importance for charter schools to illustrate that they are meeting the academic needs of the target market. This study addressed student achievement, as well as expenditure per student in both charter schools and traditional schools in the Region 10 educational service center. The datum for the study were obtained from the Texas Education Agency (TEA) website, specifically the Academic Excellence Indicator System Data (AEIS) files for the 2011-2012. The study sample included 30 open-enrollment charters schools and 30 traditional high schools within the Region 10 educational service center during the school year of 2011-2012. The research study determined significant statistical differences between open-enrollment charter schools and traditional high schools. The potential for the study was to gain additional knowledge and insight along with additional data for the open-enrollment charter schools and traditional schools in the Region 10 Educational Service Center. The study has potentially increased the information for researchers and practitioners in education. In addition this study has proved charter schools are a viable and an effective educational tool for the future.

  16. Grade level and achievement of immigrants’ children: academic redshirting in Hong Kong

    PubMed Central

    2014-01-01

    Data from Hong Kong PISA 2003 show that 15-year-old Hong Kong students who have immigrant parents from mainland China are grossly overrepresented in grades below the modal grade attended by most native Hong Kong students. Same-age comparison, when grade level is not taken into account, puts immigrants’ children at a disadvantaged position in the mathematics, reading, and science literacy tests. The academic advantage of immigrants’ children in Hong Kong is only revealed after grade is statistically controlled. Also, mainland immigrant students who are repeaters outperform native Hong Kong repeaters. Immigrant redshirting is a possible driving force behind these results. PMID:25214810

  17. Local Partnerships: Achieving Stakeholder Consensus on Low-Level Waste Disposal?

    SciTech Connect

    Hooft, E.; Bergmans, A.; Derveaux, K.; Vanhoof, L.

    2002-02-28

    Nuclear waste management is more then finding a technical answer to a technical problem. Dealing with nuclear, or any other form of hazardous waste, for that matter, not only implies solving a technical problem, it also means solving a societal problem. And societal questions cannot be resolved in a technical laboratory. Of course, the technical aspect of nuclear waste management and disposal is a very important one, but the societal aspect is of equal importance. In order to find an implementable solution to deal with nuclear waste, attention should be paid to what kind of solution the society wants and under what conditions a proposed solution might be acceptable. This, however, cannot be achieved by simply adding a number of ''societal parameters'' to a technical concept modeling. It is something that can only be established through interaction with the public concerned. And that, in addition, is not something that can be preformed as an accidental spin off of a vastly elaborated technical program. Communicating or interacting with the public does not mean sweeping them off their feet with smoothly edited leaflets explaining how technically sound the proposed solution is and how wonderful it would fit in their back yard. Adding, just to proof how brilliantly this all has been thought through, numerous safety measures, so people would feel reassured. This kind of communication, will only activate people's suspicion and drive them straight into a ''NIMBY''-reaction. The public (and by this we mean the stakeholders or the people actually concerned) should be involved in the decision making on nuclear waste from the very start of the program. This means that they must be aware of the fact that tests are taken place, that they can participate in the follow up of these technical analysis, and, that they have a say in whether further steps will eventually be taken.

    An aggressive reduction in low-density lipoprotein cholesterol (LDL-C) with statins produces regression or stabilization of coronary artery plaques. However, after achieving very low levels of LDL-C, atheroma regression is not observed in all patients. The purpose of the present study was to evaluate the determinants of atheroma progression despite achieving very low levels of LDL-C. The effects of 8-month statin therapy on coronary atherosclerosis were evaluated using virtual histology intravascular ultrasound in the TRUTH study. Of these, 33 patients who achieved an on-treatment LDL-C level of <70 mg/dl were divided into 2 groups according to increase in plaque volume (progressors, n= 16) or decrease in plaque volume (regressors, n= 17) during an 8-month follow-up period. At the 8-month follow-up, serum LDL-C and apolipoprotein B levels were significantly lower in progressors than in regressors; however, significant increases in high-density lipoprotein cholesterol and apolipoprotein AI and decreases in high-sensitivity C-reactive protein and oxidized LDL were observed only in regressors. The changes in the n-3 to n-6 polyunsaturated fatty acid ratios significantly differed between the 2 groups. Multivariate regression analysis showed that a decrease in the eicosapentaenoic acid + docosahexaenoic acid/arachidonic acid ratio was a significant predictor associated with atheroma progression (β= -0.512, p= 0.004). In conclusions, n-3 to n-6 polyunsaturated fatty acid ratios affected coronary artery plaque progression and regression in patients who achieved very low levels of LDL-C during statin therapy.

  20. Flibanserin and Female Sexual Desire.

    PubMed

    Fantasia, Heidi Collins

    2016-01-01

    Female hypoactive sexual desire disorder (HSDD) is one type of sexual problem that can affect women. It is characterized by low or absent sexual desire that cannot be attributed to another cause and results in difficulty in interpersonal relationships. HSDD is not well understood, and women may not report symptoms of difficulties to their health care providers. In August 2015, the U.S. Food and Drug Administration approved flibanserin, a nonhormonal oral medication for the treatment of HSDD in premenopausal women. Flibanserin is the only currently available pharmacologic treatment for HSDD. This article will provide an overview of flibanserin, including potential adverse reactions, special considerations for use, and implications for nursing practice. PMID:27287358

  1. Desirable Difficulties in Vocabulary Learning.

    PubMed

    Bjork, Robert A; Kroll, Judith F

    2015-01-01

    In this article we discuss the role of desirable difficulties in vocabulary learning from two perspectives, one having to do with identifying conditions of learning that impose initial challenges to the learner but then benefit later retention and transfer, and the other having to do with the role of certain difficulties that are intrinsic to language processes, are engaged during word learning, and reflect how language is understood and produced. From each perspective we discuss evidence that supports the notion that difficulties in learning and imposed costs to language processing may produce benefits because they are likely to increase conceptual understanding. We then consider the consequences of these processes for actual second-language learning and suggest that some of the domain-general cognitive advantages that have been reported for proficient bilinguals may reflect difficulties imposed by the learning process, and by the requirement to negotiate cross-language competition, that are broadly desirable. As Alice Healy and her collaborators were perhaps the first to demonstrate, research on desirable difficulties in vocabulary and language learning holds the promise of bringing together research traditions on memory and language that have much to offer each other.

    AREVA has more than 30 years experience in operating industrial HLW (High Level radioactive Waste) vitrification facilities (AVM - Marcoule Vitrification Facility, R7 and T7 facilities). This vitrification technology was based on borosilicate glasses and induction-heating. AVM was the world's first industrial HLW vitrification facility to operate in-line with a reprocessing plant. The glass formulation was adapted to commercial Light Water Reactor fission products solutions, including alkaline liquid waste concentrates as well as platinoid-rich clarification fines. The R7 and T7 facilities were designed on the basis of the industrial experience acquired in the AVM facility. The AVM vitrification process was implemented at a larger scale in order to operate the R7 and T7 facilities in-line with the UP2 and UP3 reprocessing plants. After more than 30 years of operation, outstanding record of operation has been established by the R7 and T7 facilities. The industrial startup of the CCIM (Cold Crucible Induction Melter) technology with enhanced glass formulation was possible thanks to the close cooperation between CEA and AREVA. CCIM is a water-cooled induction melter in which the glass frit and the waste are melted by direct high frequency induction. This technology allows the handling of highly corrosive solutions and high operating temperatures which permits new glass compositions and a higher glass production capacity. The CCIM technology has been implemented successfully at La Hague plant.

    Objectives The aim of this study was to evaluate the antioxidant substances present in the human diet with an antimutagenic protective capacity against genotoxic damage induced by exposure to X-rays in an attempt to reduce biological damage to as low a level as reasonably possible. Methods Ten compounds were assessed using the lymphocyte cytokinesis-block micronucleus (MN) cytome test. The compounds studied were added to human blood at 25 μM 5 min before exposure to irradiation by 2 Gy of X-rays. Results The protective capacity of the antioxidant substances assessed was from highest to lowest according to the frequency of the MN generated by X-ray exposure: rosmarinic acid = carnosic acid = δ-tocopherol = l-acid ascorbic = apigenin = amifostine (P < 0.001) > green tea extract = diosmine = rutin = dimetylsulfoxide (P < 0.05) > irradiated control. The reduction in genotoxic damage with the radiation doses administered reached 58%, which represents a significant reduction in X-ray-induced chromosomal damage (P < 0.001). This degree of protection is greater than that obtained with amifostine, a radioprotective compound used in radiotherapy and which is characterised by its high toxicity. Conclusion Several antioxidant substances, common components of the human diet and lacking toxicity, offer protection from the biological harm induced by ionizing radiation. Administering these protective substances to patients before radiological exploration should be considered, even in the case of small radiation doses and regardless of the biological damage expected.

    This study explored the relationship between the grades students earned in introductory college microbiology and American College Testing scores, sex, race, age, GED or high school diploma, full-time or part-time student status, developmental reasoning levels, memory tactics, and expected achievement. The study also explored student perceptions at the beginning and the end of the microbiology courses for science preparation, expected achievement, relevancy of microbiology, and expectations for the course. Archival records for 121 freshman level and 119 sophomore level microbiology students were accessed to obtain final grades, ACT scores, sex, race, age, GED or high school diploma and full-time or part-time status. The same information was obtained for the 113 freshman level and the 85 sophomore level students who participated in the study. The study groups were given the Group Assessment of Logical Thinking to assess their level of formal reasoning ability, the Inventory of Learning Processes-Revised to assess three memory techniques, an initial perception survey, and an exit perception survey. Academic achievement in microbiology could not be predicted using composites of the predictor variables. There were significant relationships between the GALT scores and the predicted grades with both the freshman and the sophomore final grades. The Self-Efficacy Fact Retention scores and the Literal Memorization scores had significant relationships to the final grades of the freshmen but not the sophomores. There was not a significant relationship between the Deep Semantic scores and the final grades in either group. Students indicated that high school science had given them only a medium to low level of preparation for college microbiology. The sophomores felt that previous college science classes had given them a much better preparation for microbiology than did the freshmen students. Both groups expressed the importance of the laboratory experience to the understanding

    High healthcare cost has drawn much attention and healthcare service providers (HSPs) are expected to deliver high-quality and consistent care. Therefore, an intimate understanding of the most desirable experience from a patient's and/or family's perspective as well as effective mapping and communication of such findings should facilitate HSPs' efforts in attaining sustainable competitive advantage in an increasingly discerning environment. This study describes (a) the critical quality attributes (CQAs) of the experience desired by patients and (b) the application of two visualization tools that are relatively new to the healthcare sector, namely the "spider-web diagram" and "promotion and detraction matrix." The visualization tools are tested with primary data collected from telephone surveys of 1,800 patients who had received care during calendar year 2005 at 6 of 61 hospitals within St. Louis, Missouri-based, Ascension Health. Five CQAs were found by factor analysis. The spider-web diagram illustrates that communication and empowerment and compassionate and respectful care are the most important CQAs, and accordingly, the promotion and detraction matrix shows those attributes that have the greatest effect for creating promoters, preventing detractors, and improving consumer's likelihood to recommend the healthcare provider.

    Background Bone graft material for lumbar fusion was historically autologous bone graft (ABG). In recent years alternatives such as allograft, demineralized bone matrix (DBM), ceramics, and bone morphogenetic protein (BMP) have gained favor, although the complications of these are not fully understood. Bioactive amniotic suspension (BAS) with allograft is a new class of material derived from human amniotic tissue. Methods Eligible patients receiving a one or two level lumbar interbody fusion with Nucel, a BAS with allograft, were contacted and scheduled for a mininmim 12 month follow-up visit. Patients were evaluated for fusion using CT's and plain radiographs. Clincal outcomes, including ODI, VAS back and leg were collected, as well as comorbidities including BMI, smoking status, diabetes and previous lumbar surgery. Results One-level patients (N=38) were 71.1% female with mean age of 58.4 ± 12.7 and mean BMI of 30.6 ± 6.08. Two-level patients (N=34) were 58.8% female with mean age of 49.3 ±10.9 and mean BMI of 30.1 ± 5.82. Kinematic fusion was achieved in 97.4% of one-level patients and 100% of two-level patients. Baseline comorbidities were present in 89.5% of one-level patients and 88.2% of two-level patients. No adverse events related to BAS were reported in this study. Conclusion Fusion status is evaluated with many different biologics and varying methods in the literature. BAS with allograft in this study demonstrated high fusion rates with no complications within a largely comorbid population. Although a small population, BAS with allograft results were encouraging for one and two-level lumbar interbody fusion in this study. Further prospective studies should be conducted to investigate safety and efficacy in a larger population. PMID:27162714

    The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in the Marine Climate Region on a cost neutral basis.

    2010-01-01

    Introduction A number of questionnaires have been created to assess levels of sexual desire in women, but to our knowledge, there are currently no validated measures for assessing cues that result in sexual desire. A questionnaire of this nature could be useful for both clinicians and researchers, because it considers the contextual nature of sexual desire and it draws attention to individual differences in factors that can contribute to sexual desire. Aim The aim of the present study was to create a multidimensional assessment tool of cues for sexual desire in women that is validated in women with and without hypoactive sexual desire disorder (HSDD). Methods Factor analyses conducted on both an initial sample (N = 874) and a community sample (N = 138) resulted in the Cues for Sexual Desire Scale (CSDS) which included four factors: (i) Emotional Bonding Cues; (ii) Erotic/ Explicit Cues; (iii) Visual/Proximity Cues; and (iv) Implicit/Romantic Cues. Main Outcome Measures Scale construction of cues associated with sexual desire and differences between women with and without sexual dysfunction. Results The CSDS demonstrated good reliability and validity and was able to detect significant differences between women with and without HSDD. Results from regression analyses indicated that both marital status and level of sexual functioning predicted scores on the CSDS. The CSDS provided predictive validity for the Female Sexual Function Index desire and arousal domain scores, and increased cues were related to a higher reported frequency of sexual activity in women. Conclusions The findings from the present study provide valuable information regarding both internal and external triggers that can result in sexual desire for women. We believe that the CSDS could be beneficial in therapeutic settings to help identify cues that do and do not facilitate sexual desire in women with clinically diagnosed desire difficulties.

    The 2012 American College of Clinical Pharmacy (ACCP) Certification Affairs Committee was charged with developing guidelines for the desired professional development pathways for clinical pharmacists. This document summarizes recommendations for postgraduate education and training for graduates of U.S. schools and colleges of pharmacy and describes the preferred pathways for achieving, demonstrating, and maintaining competence as clinical pharmacists. After initial licensure within the state or jurisdiction in which the pharmacist intends to practice, completion of an accredited PGY1 pharmacy residency is recommended to further develop the knowledge and skills needed to optimize medication therapy outcomes. An accredited PGY2 pharmacy residency should be completed if a pharmacist wishes to seek employment in a specific therapeutic area or practice setting, if such a residency exists. Clinical pharmacists intending to conduct advanced research that is competitive for federal funding are encouraged to complete a fellowship or graduate education. Initial certification by the Board of Pharmacy Specialties (BPS) or other appropriate sponsoring organizations should be completed in the desired primary therapeutic area or practice setting within 2 years after accepting a position within the desired specific therapeutic area or practice setting. Clinical pharmacists subsequently will need to meet the requirements to maintain pharmacist licensure and board certification. Traineeships, practice-based activities, and certificate programs can be used to obtain additional knowledge and skills that support professional growth. Pharmacists are strongly encouraged to adopt a lifelong, systematic process for professional development and work with ACCP and other professional organizations to facilitate the development and implementation of innovative strategies to assess core practice competencies.

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards

    Purpose of the study. This study was designed to measure the effects of CD-ROM textbook integration on student achievement and student cognition-level-attainment for undergraduate general biology students. Four sections of general biology were selected as the study group. Two sections served as the experimental group receiving CD-ROM textbook integration. The remaining two sections served as the control group, and were taught biological content utilizing a traditional textbook. Procedure. This study employed a pre-experimental research design, static group comparison (Ary, Jacobs, & Razavieh, 1996: 331), to determine if a CD-ROM textbook had significant effects on student cognition-level-attainment and content achievement of undergraduate biology students. The study was conducted during the 2001 spring semester at Southeastern Oklahoma State University. The duration of the treatment was approximately sixteen weeks. Four sections of general biology (N = 101) were selected as the study group. Two of the four sections of general biology (n = 48) were randomly selected by the researcher via coin toss to serve as the experimental group, Group A, and were taught biological content utilizing a CD-ROM Textbook. The remaining two sections of general biology (n = 53) served as the control group, Group B, and were taught biological content utilizing a traditional textbook. Various statistical tests were used in analysis of the data. The ten null hypotheses were tested at the .05 level of significance. The Statistical Package for the Social Sciences program (SPSS), version 9.0 (SPSS, 1999), was used to process the data. Results. The results determined by this study were the overall effects of the CD-ROM textbook did not significantly differ from the effects of the traditional textbook on student content achievement and cognition-level-attainment. Conclusions. The utilization of CD-ROM textbook instruction is not superior at improving student achievement of biology content, as

    Plant oils containing {omega}-7 fatty acids (FAs; palmitoleic 16:1{Delta}{sup 9} and cis-vaccenic 18:1{Delta}{sup 11}) have potential as sustainable feedstocks for producing industrially important octene via metathesis chemistry. Engineering plants to produce seeds that accumulate high levels of any unusual FA has been an elusive goal. We achieved high levels of {omega}-7 FA accumulation by systematic metabolic engineering of Arabidopsis (Arabidopsis thaliana). A plastidial 16:0-ACP desaturase has been engineered to convert 16:0 to 16:1{Delta}{sup 9} with specificity >100-fold than that of naturally occurring paralogs, such as that from cat's claw vine (Doxantha unguis-cati). Expressing this engineered enzyme (Com25) in seeds increased {omega}-7 FA accumulation from <2% to 14%. Reducing competition for 16:0-ACP by down-regulating the {beta}-ketoacyl-ACP synthase II 16:0 elongase further increased accumulation of {omega}-7 FA to 56%. The level of 16:0 exiting the plastid without desaturation also increased to 21%. Coexpression of a pair of fungal 16:0 desaturases in the cytosol reduced the 16:0 level to 11% and increased {omega}-7 FA to as much as 71%, equivalent to levels found in Doxantha seeds.

    Despite being one of the most common orthopaedic operations, it is still not known how many arthroscopies of the knee must be performed during training in order to develop the skills required to become a Consultant. A total of 54 subjects were divided into five groups according to clinical experience: Novices (n = 10), Junior trainees (n = 10), Registrars (n = 18), Fellows (n = 10) and Consultants (n = 6). After viewing an instructional presentation, each subject performed a simple diagnostic arthroscopy of the knee on a simulator with visualisation and probing of ten anatomical landmarks. Performance was assessed using a validated global rating scale (GRS). Comparisons were made against clinical experience measured by the number of arthroscopies which had been undertaken, and ROC curve analysis was used to determine the number of procedures needed to perform at the level of the Consultants. There were marked differences between the groups. There was significant improvement in performance with increasing experience (p < 0.05). ROC curve analysis identified that approximately 170 procedures were required to achieve the level of skills of a Consultant. We suggest that this approach to identify what represents the level of surgical skills of a Consultant should be used more widely so that standards of training are maintained through the development of an evidenced-based curriculum.

    The cell topic was taught to 9th-grade students in three modes of instruction: (a) students "hands-on," who constructed three-dimensional cell organelles and macromolecules during the learning process; (b) teacher demonstration of the three-dimensional model of the cell structures; and (c) teaching the cell topic with the regular learning material in an expository mode (which use one- or two-dimensional cell structures as are presented in charts, textbooks and microscopic slides). The sample included 669, 9th-grade students from 25 classes who were taught by 22 Biology teachers. Students were randomly assigned to the three modes of instruction, and two tests in content knowledge in Biology were used. Data were treated with multiple analyses of variance. The results indicate that entry behavior in Biology was equal for all the study groups and types of schools. The "hands-on" learning group who build three-dimensional models through the learning process achieved significantly higher on academic achievements and on the high and low cognitive questions' levels than the other two groups. The study indicates the advantages students may have being actively engaged in the learning process through the "hands-on" mode of instruction/learning.

    Human traits tend to fall along normal distributions. The aim of this research was to evaluate an evidence-based conceptual framework for predicting expected individual differences in reading and writing achievement outcomes for typically developing readers and writers in early and middle childhood from Verbal Reasoning with or without Working Memory Components (phonological, orthographic, and morphological word storage and processing units, phonological and orthographic loops, and rapid switching attention for cross-code integration). Verbal Reasoning (reconceptualized as Bidirectional Cognitive-Linguistic Translation) plus the Working Memory Components (reconceptualized as a language learning system) accounted for more variance than Verbal Reasoning alone, except for handwriting for which Working Memory Components alone were better predictors. Which predictors explained unique variance varied within and across reading (oral real word and pseudoword accuracy and rate, reading comprehension) and writing (handwriting, spelling, composing) skills and grade levels (second and fifth) in this longitudinal study. Educational applications are illustrated and theoretical and practical significance discussed. PMID:24948868

    This article presents a study whose objective was to identify certain personal and institutional variables that are associated with academic achievement among Spanish, secondary school students, and to analyze their influence on the progress of those students over the course of that stage of their education. In order to do this, a longitudinal, multi-level study was conducted in which a total of 965 students and 27 different schools were evaluated in Language, Math and Social Science at three different times (beginning, middle and end of the period). The results show progress in all the schools and in all areas. As for the personal, student variables, the longitudinal, HLM analyses confirmed the importance of sex and sociocultural background and, distinguishing it from other studies, also the predictive capacity of meta-cognitive abilities and learning strategies on success in school. On the institutional level, the school climate and teachers' expectations of their students were the most relevant of the variables studied. The size of the school, the percentage of students who repeat grades, and the leadership of the administration also explained a portion of the variance in some areas. PMID:18988427

    2012-01-01

    Background Medical cannabis dispensaries following the social or hybrid model offer supplementary holistic services in addition to dispensing medical cannabis. Historically, alternative physical health services have been the norm for these dispensaries, including services such as yoga, acupuncture, or chiropractor visits. A clinical service dearth remains for medical cannabis patients seeking substance use, misuse, dependence, and mental health services. This study examined patient desires for various clinical services and level of willingness to participate in specific clinical services. Methods Anonymous survey data (N = 303) were collected at Harborside Health Center (HHC), a medical cannabis dispensary in Oakland, CA. The sample was 70% male, 48% Caucasian and 21% African American. The mean male age was 38 years old and female mean age was 30. Sixty two percent of the male participants and 44% of the female participants are single. Sixteen percent of the population reported having a domestic partner. Forty six percent of the participants are employed full time, 41% have completed at least some college, and 49% make less than $40,000 a year. Results A significant portion of the sample, 62%, indicated a desire to participate in free clinical services at HHC, 34% would like more information about substances and use, and 41% want to learn more about reducing harms from substance use. About one quarter of the participants marked "would" or "likely would" participate in individual services such as consultation. Approximately 20% indicated "would" or "likely would" participate in psycho-educational forums, harm reduction information sharing sessions, online support groups, and coping, life, and social skills group. There was little interest in traditional NA/AA 12-step groups or adapted 12-step groups. Conclusions Desired clinical services can be qualified as a combination of harm reduction, educational, skills-based, peer support and therapeutic individual and group

    A primary objective of the US Department of Energy (DOE) health physics and radiation protection program has been to limit radiation exposures to those levels that are as low as reasonably achievable (ALARA). As a result, the ALARA concept developed into a program and a set of operational principles to ensure that the objective was consistently met. Implementation of these principles required that a guide be produced. The original ALARA guide was issued by DOE in 1980 to promote improved understanding of ALARA concepts within the DOE community and to assist those responsible for operational ALARA activities in attaining their goals. Since 1980, additional guidance has been published by national and international organizations to provide further definition and clarification to ALARA concepts. As basic ALARA experience increased, the value and role of the original guide prompted the DOE Office of Nuclear Safety (ONS) to support a current revision. The revised manual of good practices includes six sections: 1.0 Introduction, 2.0 Administration, 3.0 Optimization, 4.0 Setting and Evaluating ALARA Goals, 5.0 Radiological Design, and 6.0 Conduct of Operations. The manual is directed primarily to contractor and DOE staff who are responsible for conduct and overview of radiation protection and ALARA programs at DOE facilities. The intent is to provide sufficient guidance such that the manual, if followed, will ensure that radiation exposures are maintained as low as reasonably achievable and will establish the basis for a formally structured and auditable program. 118 refs., 16 figs., 3 tabs.

  7. A Dyadic Operator for the Gradation of Desirability

    NASA Astrophysics Data System (ADS)

    Piolle, Guillaume

    We propose a normal modal deontic logic based on a dyadic operator, similar in structure to the temporal "until". By bringing significant expressiveness to the logic, it allows both the definition of a monadic desirability operator similar to the SDL obligation, and the expression of the relative level of desirability of target formulae. The interpretation of this logic on a linear structure of worlds ordered by desirability makes its semantics more intuitive and concrete than the SDL deontic accessibility relation. We also show that the core modality of the logic permits to represent the Chisholm and Forrester paradoxes of deontic logic in a more precise way, which does not lead to inconsistencies.

  10. The effect of retesting on end-of-semester performance in high school chemistry at three levels of previous science achievement

    NASA Astrophysics Data System (ADS)

    Deboer, George E.

    To determine the effect of retesting on student learning in chemistry, three questions were addressed by means of a 3 × 2 (achievement level X treatment) factorial design: (1) Does retesting affect differently the end-of-semester mastery of course objectives of students who are grouped according to their previous achievement in science? (2) Do students who are given an opportunity to take retests merely delay their studying and perform at a lower level on initial tests than nonretested students? (3) Is the procrastination of retested students (if it exists) affected by their achievement level? The results showed that for one of four units low ability students who were retested demonstrated greater learning gains than low ability students who were not retested, and that procrastination, if it was present, did not have significant effects on student learning at any achievement level. Results were discussed in terms of the students' room for improvement, motivation to improve, and ability to improve.

    A new type of Grating Image we dominate as `Sparklegram' is presented. The Sparklegram is characterized because it provides high quality and better design flexibility. These features are achieved by constructing it with shaped dots as desired. Each dot can be designed as an individual shape, for example, a star or a triangle. As dot shapes, we can use not only geometric patterns, but also some kind of symbols. Not only flexibility of each consists dot shape, but also the quality of reconstructed image is remarkably increased too. Because of these features, the constructed image with the new type of Grating Image, Sparklegram has high quality and high flexibility. It can be applied to security use, for example on credit-cards, tickets, etc., and also can be applied to the package of software products, CDs, videos and other kind of items requiring security. And with these features of flexibility and high quality, Sparklegram has also advantages to be applied to other use, for example amusement use, comics and game characters' goods and packages.

  12. Virtual, on-line, frog dissection vs. conventional laboratory dissection: A comparison of student achievement and teacher perceptions among honors, general ability, and foundations-level high school biology classes

    2002-09-01

    Dissecting animal specimens has long been a tradition in biology classes. Objections by students, based on religious or ethical grounds, have been raised regarding the dissections of animals in classroom laboratories. A number of states now have legal proceedings or statewide policies requiring that alternatives to the actual dissection of laboratory animal specimens be permitted in their school districts. Alternatives to actual dissections have been developed in recent years. For a variety of reasons, performing an actual or conventional animal dissection may not be a desirable option. The purpose of this study was to investigate how a virtual On-line frog dissection compares with an actual laboratory dissection. What were the perceptions of the teacher's using it? How does student achievement compare among three the different ability levels on a pre and posttest regarding basic frog anatomy? Is a virtual On-line dissection a suitable alternative for students who, for whatever reason, do not participate in the actual laboratory experience? The subjects consisted of 218 biology students among three different ability levels, in a Northeastern suburban high school. Approximately half of the student groups participated in a virtual On-line dissection, the other half in an actual laboratory dissection. A pretest of basic frog anatomy was administered to the students two days before and the posttest one day after their dissection experience. Data were analyzed using matched pairs t-Tests, Analysis of Variance, Tukey HSD, and Squared Curvilinear Coefficients. Survey questionnaires were administered to the teachers after the dissection experiences were completed. There were no significant differences found in achievement between the virtual and conventional dissection groups. There were significant differences found in achievement score means among the three ability levels. There was no significant interaction between gender and achievement. Perceptions of the teacher

  17. Social desirability and sexual offenders: a review.

    PubMed

    Tan, Lavinia; Grace, Randolph C

    2008-03-01

    Social desirability--the desire to make a favorable impression on others-poses a significant threat to the validity of self-reports. This review examines research on social desirability in both forensic and nonforensic populations with the goal of identifying how best to minimize threats to the validity of research with sexual offenders. Although social desirability has long been a major research topic in personality, consensus has not been reached on key questions such as its dimensional structure and whether social desirability constitutes a trait or a response bias. Research with offenders has shown that social desirability is negatively related to recidivism and that different offender subtypes vary in the degree to which social desirability appears to influence self-reports, with child molesters exhibiting the strongest tendency to "fake good." Several methods of controlling for social desirability have been proposed, but the effectiveness of these methods in increasing validity of offender self reports is questionable. Given the lack of consensus in the personality literature, a fresh start is needed in which basic questions regarding social desirability are revisited with respect to offender populations.

    Bogaert, Anthony F; Brotto, Lori A

    2014-01-01

    In this article, the authors discuss the construct of object of desire self-consciousness, the perception that one is romantically and sexually desirable in another's eyes. The authors discuss the nature of the construct, variations in its expression, and how it may function as part of a self-schemata or script related to romance and sexuality. The authors suggest that object of desire self-consciousness may be an adaptive, evolved psychological mechanism allowing sexual and romantic tactics suitable to one's mate value. The authors also suggest that it can act as a signal that one has high mate value in the sexual marketplace. The authors then review literature (e.g., on fantasies, on sexual activity preferences, on sexual dysfunctions, on language) suggesting that object of desire self-consciousness plays a particularly important role in heterosexual women's sexual/romantic functioning and desires.

  6. The relationship of attitudes toward science, cognitive style, and self-concept to achievement in chemistry at the secondary school level

    NASA Astrophysics Data System (ADS)

    Kirk, Gerald Richard

    There is currently a crisis in science education in the United States. This statement is based on the National Science Foundation's report stating that the nation's students, on average, still rank near the bottom in science and math achievement internationally. This crisis is the background of the problem for this study. This investigation studied learner variables that were thought to play a role in teaching chemistry at the secondary school level, and related them to achievement in the chemistry classroom. Among these, cognitive style (field dependence/independence), attitudes toward science, and self-concept had been given considerable attention by researchers in recent years. These variables were related to different competencies that could be used to measure the various types of achievement in the chemistry classroom at the secondary school level. These different competencies were called academic, laboratory, and problem solving achievement. Each of these chemistry achievement components may be related to a different set of learner variables, and the main purpose of this study was to investigate the nature of these relationships. Three instruments to determine attitudes toward science, cognitive style, and self-concept were used for data collection. Teacher grades were used to determine chemistry achievement for each student. Research questions were analyzed using Pearson Product Moment Correlation Coefficients and t-tests. Results indicated that field independence was significantly correlated with problem solving, academic, and laboratory achievement. Educational researchers should therefore investigate how to teach students to be more field independent so they can achieve at higher levels in chemistry. It was also true that better attitudes toward the social benefits and problems that accompany scientific progress were significantly correlated with higher achievement on all three academic measures in chemistry. This suggests that educational researchers

    A standards-based, service-oriented architecture for clinical decision support (CDS) has the potential to significantly enhance CDS scalability and robustness. To enable such a CDS architecture, the Health Level 7 CDS Work Group reviewed the literature, hosted multi-stakeholder discussions, and consulted domain experts to identify and prioritize the services and capabilities required from clinical information systems (CISs) to enable service-oriented CDS. In addition, relevant available standards were identified. Through this process, ten CIS services and eight CIS capabilities were identified as being important for enabling scalable, service-oriented CDS. In particular, through a survey of 46 domain experts, five services and capabilities were identified as being especially critical: 1) the use of standard information models and terminologies; 2) the ability to leverage a Decision Support Service (DSS); 3) support for a clinical data query service; 4) support for an event subscription and notification service; and 5) support for a user communication service.

    The achievement of recommended levels (≥ 30 min/day) of school moderate-to-vigorous physical activity (MVPA) is paramount to decrease risk of chronic disease in children from low-income families. The purpose of this study was to examine the predictors and grade-level trends of school day MVPA achievement in low-income children. Data were collected during the Fall of 2014 on 1232 children (Mean age = 8.8 ± 1.6 years; 625 girls, 607 boys) recruited from three low-income schools from the state of Utah in the U.S. Children wore pedometers for one school week and a stratified random subsample (n = 533) also wore accelerometers to record sedentary time and MVPA. Generalized linear mixed models were employed to calculate odds ratios for achieving school MVPA standards (≥ 30 min/day) from various predictors and to determine odds of achievement across grade levels, accounting for school and classroom clustering. Odds of meeting MVPA standards were 3 times greater if a student achieved at least 6000 steps during the school day (p < 0.01), and were 55% lower for every 1% increase in sedentary time (p < 0.001). Older children had 26% lower odds of meeting the recommended levels of MVPA compared to children in an immediately younger grade level (p < 0.05). A significant proportion of MVPA variance was explained by classroom and school affiliation (Rho = 0.09 to 0.54, p < 0.001). Daily steps, sedentary times, grade level, and classroom and school affiliation associate with school MVPA achievement in low-income children. PMID:26844162

    Sexually compulsive males report extremely high rates of desire involving paraphiliac activity. Desire and arousal in partner sex is usually low or unstable. Cognitive-behavioral strategies and techniques are presented based on four components in the assessment/intervention process: 1) eliminating or reducing paraphiliac arousal; 2) sex education, changing sexual attitudes, self-disclosure, sexual assertiveness, and reduction of guilt and shame; 3) confronting secrecy and cognitive distortions, increasing empathy for victims, awareness of harm to others, and commitment to abstain from compulsive, abusive behavior; and 4) developing a healthy sexual desire and arousal pattern that nurtures and maintains an intimate relationship. The motivated male (especially with a partner he is comfortable with, attracted to, and trusts) can develop a pleasurable, erotic sexual pattern that allows him to maintain desire during partner sex.

    Heparins are glycosaminoglycans that, in addition to their anticoagulant activity, have interactions with growth factors and other glycoproteins. These interactions may stimulate neointimal hyperplasia when heparin is delivered locally on stents and stent-grafts. Modifying the structure of heparin to retain anticoagulant activity while minimizing these stimulatory effects on the vascular endothelium is desirable and may be achieved by understanding the relationships between the structure and function of the various parts of the heparin molecule.

    Introduction studies have indicated that emotional intelligence is positively related to self-efficacy and can predict the academic achievement. The present study aimed to investigate the role of emotional intelligence in identifying self-efficacy among the students of Public Health School with different levels of academic achievement. Methods This correlational study was conducted on all the students of Public Health School. 129 students were included in the study through census method. Data were collected using Emotional Intelligence and self-efficacy questionnaires and analyzed using descriptive statistics and regression analysis by SPSS 14. Results The average score of students with high academic achievement was higher in self-efficacy (39.78±5.82) and emotional intelligence (117.07±10.33) variables and their components than that of students with low academic achievement (39.17±5.91, 112.07±13.23). The overall emotional intelligence score to predict self-efficacy explanation was different among students with different levels of academic achievement (p<0.001). Self-efficacy structure was explained through self-awareness and self-motivation components in students with low academic achievement (r=0.571). In students with high academic achievement, self-awareness, self-motivation and social consciousness played an effective role in explaining self-efficacy (r=0.677, p<0.001). Conclusion Emotional intelligence and self-efficacy play an important role in achieving academic success and emotional intelligence can explain self-efficacy. Therefore, it is recommended to teach emotional intelligence skills to students with low academic achievement through training workshops. PMID:25927067

    Kingsberg, Sheryl A; Woodard, Terri

    2015-02-01

    Low or absent sexual desire is the most common sexual dysfunction in women, and its prevalence peaks during midlife. Its etiology is complex and may include biologic, psychologic, and social elements. Major risk factors for its development include poor health status, depression, certain medications, dissatisfaction with partner relationship, and history of physical abuse, sexual abuse, or both. Diagnosis is based on criteria set by the Diagnostic and Statistical Manual of Mental Disorders (5th Edition) and requires that a woman experience personal distress. Clinical evaluation should include medical history, sexual history, and, sometimes, a physical examination. Laboratory data are of limited value, except when warranted by history or physical examination. Treatment options include nonpharmacologic interventions such as education, office-based counseling, and psychotherapy. Although there are no U.S. Food and Drug Administration (FDA)-approved treatments for low desire, pharmacologic agents have been used off-label for this purpose. Bupropion is an antidepressant that has been shown to improve desire in some women with and without depression. Systemic estrogen therapy is not recommended in the absence of vasomotor symptoms and is not directly associated with desire. However, vaginal estrogen is useful in patients presenting with concomitant vaginal atrophy and dyspareunia. Ospemifene is a selective estrogen receptor modulator that can be used as an alternative to vaginal estrogen. Exogenous testosterone has demonstrated efficacy in treating loss of desire in postmenopausal women. However, patients should be counseled that it is not FDA-approved for this purpose and there are limited published long-term safety data. Several agents for the treatment of low desire are currently in development. Gynecologists are in a unique position to address concerns about sexual desire in women. PMID:25569014

    2015-08-01

    In the current study we explored the role of desire thinking in predicting binge eating independently of Body Mass Index, negative affect and irrational food beliefs. A sample of binge eaters (n=77) and a sample of non-binge eaters (n=185) completed the following self-report instruments: Hospital Anxiety and Depression Scale, Irrational Food Beliefs Scale, Desire Thinking Questionnaire, and Binge Eating Scale. Mann-Whitney U tests revealed that all variable scores were significantly higher for binge eaters than non-binge eaters. A logistic regression analysis indicated that verbal perseveration was a predictor of classification as a binge eater over and above Body Mass Index, negative affect and irrational food beliefs. A hierarchical regression analysis, on the combined sample, indicated that verbal perseveration predicted levels of binge eating independently of Body Mass Index, negative affect and irrational food beliefs. These results highlight the possible role of desire thinking as a risk factor for binge eating. PMID:25880044

    2016-08-01

    This study evaluates sex differences in the perceived desirability of personality behaviors and beliefs. Men and women (N = 149, Mage  = 18.7) judged the social desirability scale values (SDSVs) of 150 personality statements as applied either to a male target or a female target. For comparison, some estimated SDSVs with no target sex specified. A separate sample of 537 respondents endorsed the 150 items via self-report. Raters showed a high consensus in their SDSV judgments within conditions (α = .86 to .90) and no sex-of-rater effects across conditions. Substantial sex-of-target effects (p < .001), however, revealed many behaviors that were viewed as desirable for one sex but not for the other. The behaviors seen as more (less) desirable when applied to men rather than to women were endorsed more (less) by men than by women in the respondent sample. Similar results were found when no target sex was specified for the SDSV ratings, presumably because judges evaluated the behaviors as applied to a target of their own sex. The present results have important implications for the measurement and reporting of SDSVs, the evaluation of substance versus style in self-reports, and the construction of desirability-reduced personality inventories.

    2004-08-01

    One hundred and sixty-two participants (ages 21-45) wrote open-ended sexual fantasies and completed self-report measures of rape myth acceptance, adversarial sexual beliefs, and attitudes toward women. We coded fantasies using a newly developed scoring system that includes themes of dominance, submission, sexual pleasure, and sexual desire. Men fantasized about dominance more than women did; they also tended to focus more on the desire and pleasure of their partner. Desire and pleasure were more closely linked in the fantasies of men than in the fantasies of women, for whom the two were distinct constructs. Although fantasies of submission were not associated with problematic attitudes for either gender, men's fantasies of dominance were associated with greater acceptance of rape myths. For women, greater rape myth acceptance was associated with emotional and romantic fantasy themes. PMID:15497057

  14. Some Suggested Techniques for Achieving Required Main Ring Low Level RF Performance for the Tevatron I Program

    SciTech Connect

    Griffin, J.E.; MacLachlan, J.

    1984-05-01

    These techniques are derived from experience with the existing low level rf system and from the results of accelerator experiments directed at the Tev I requirements which were performed using a specially modified low level rf system. The techniques suggested here are not necessarily unique and other techniques may be acceptable. It is important to realize that certain performance requirements on the Booster and Main Ring are substantially different in the Tev I program from those which have been acceptable in the fixed target program. For example, the longitudinal emittance of the bunches has been routinely and intentionally blown up by the 'bunch spreader' during acceleration to improve the smoothness of the spill. In the Tev I case, the 'bunch narrowing' procedure preceding {bar p} production and in bunch coalescing is facilitated by maintaining the smallest possible longitudinal emittance (i.e. the largest possible longitudinal phase space density). Also, during fixed target physics the Main Ring is essentially full (i.e. approx. 1090 of 1113 buckets occupied) so transient beam loading of the rf system is negligible except during injection, whereas for {bar p} production a single high intensity Booster batch (approx. 83 bunches) is to be accelerated causing substantial transient beam induced phase shift of the rf voltage during each passage. The low level phase and position error signals are normally derived from an essentially full ring during fixed target operation whereas in the Tev I program the systems must perform adequately with as few as ten adjacent buckets occupied. Because of the differences in emphasis between fixed target operation and Tevatron I operation is seems sensible to use separate low level rf systems for these two modes of operation. If a single low level system were to be used for both modes of operation some compromises may be necessary which might cause performance in either mode to be less than adequate. Because of the severe demands

  19. Goal desires moderate intention-behaviour relations.

    PubMed

    Prestwich, Andrew; Perugini, Marco; Hurling, Robert

    2008-03-01

    Models such as the Extended Model of Goal-Directed Behaviour and the Theory of Planned Behaviour imply that the impact of one's goals on behaviour is mediated by more proximal determinants. We hypothesize that goals can have a broader and more dynamic impact on behaviour and, specifically, that goal desires can moderate the effect of intentions on behaviour. Four studies addressed this issue by examining the direct and moderated effects of goal desires on behaviour. All of the studies required participants to complete baseline measures and then a follow-up indicator of behaviour. In Study 1 (N=119) that focused on fruit intake, Study 2 (N=123) and Study 3 (N=96) concerned with drinking alcohol and Study 4 (N=109) regarding snack consumption, behavioural intentions were more reliably related to behaviour when goal desires were strong. The results of Study 3 suggested that goal desire stability increases the likelihood of this moderator effect emerging and Study 4 revealed that this effect was not suppressed by intention stability. The findings suggest that goals and behavioural intentions can operate simultaneously and jointly influence action, a view that contradicts predictions that the effects of goals are fully mediated by more proximal behavioural determinants.

    2008-02-15

    This paper focuses on the accuracy, in absolute dose measurements, with GafChromic EBT film achievable in water for a 6 MV photon beam up to a dose of 2.3 Gy. Motivation is to get an absolute dose detection system to measure up dose distributions in a (water) phantom, to check dose calculations. An Epson 1680 color (red green blue) transmission flatbed scanner has been used as film scanning system, where the response in the red color channel has been extracted and used for the analyses. The influence of the flatbed film scanner on the film based dose detection process was investigated. The scan procedure has been optimized; i.e. for instance a lateral correction curve was derived to correct the scan value, up to 10%, as a function of optical density and lateral position. Sensitometric curves of different film batches were evaluated in portrait and landscape scan mode. Between various batches important variations in sensitometric curve were observed. Energy dependence of the film is negligible, while a slight variation in dose response is observed for very large angles between film surface and incident photon beam. Improved accuracy in absolute dose detection can be obtained by repetition of a film measurement to tackle at least the inherent presence of film inhomogeneous construction. We state that the overall uncertainty is random in absolute EBT film dose detection and of the order of 1.3% (1 SD) under the condition that the film is scanned in a limited centered area on the scanner and at least two films have been applied. At last we advise to check a new film batch on its characteristics compared to available information, before using that batch for absolute dose measurements.

    2015-01-01

    STUDY QUESTION Until what age can couples wait to start a family without compromising their chances of realizing the desired number of children? SUMMARY ANSWER The latest female age at which a couple should start trying to become pregnant strongly depends on the importance attached to achieving a desired family size and on whether or not IVF is an acceptable option in case no natural pregnancy occurs. WHAT IS KNOWN ALREADY It is well established that the treatment-independent and treatment-dependent chances of pregnancy decline with female age. However, research on the effect of age has focused on the chance of a first pregnancy and not on realizing more than one child. STUDY DESIGN, SIZE, DURATION An established computer simulation model of fertility, updated with recent IVF success rates, was used to simulate a cohort of 10 000 couples in order to assess the chances of realizing a one-, two- or three-child family, for different female ages at which the couple starts trying to conceive. PARTICIPANTS/MATERIALS, SETTING, METHODS The model uses treatment-independent pregnancy chances and pregnancy chances after IVF/ICSI. In order to focus the discussion, we single out three levels of importance that couples could attach to realizing a desired family size: (i) Very important (equated with aiming for at least a 90% success chance). (ii) Important but not at all costs (equated with a 75% success chance) (iii) Good to have children, but a life without children is also fine (equated with a 50% success chance). MAIN RESULTS AND THE ROLE OF CHANCE In order to have a chance of at least 90% to realize a one-child family, couples should start trying to conceive when the female partner is 35 years of age or younger, in case IVF is an acceptable option. For two children, the latest starting age is 31 years, and for three children 28 years. Without IVF, couples should start no later than age 32 years for a one-child family, at 27 years for a two-child family, and at 23 years for

    2011-05-01

    The interaction between women's hormonal condition and subjective, physiological, and behavioral indices of desire or arousal remains only partially explored, in spite of frequent reports from women about problems with a lack of sexual desire. The present study recruited premenopausal women at two sites, one in the United States and the other in the Netherlands, and incorporated various measures of acute changes in sexual desire and arousal. A sample of 46 women who met criteria for Hypoactive Sexual Desire Disorder (HSDD) was compared to 47 women who experienced no sexual problems (SF). Half of each group used oral contraceptives (OCs). The specific goal was to investigate whether there is a relationship between women's hormone levels and their genital and subjective sexual responsiveness. Background demographics and health variables, including oral contraceptive (OC) use, were recorded and hormones (total testosterone (T), free testosterone (FT), SHBG, and estradiol) were analyzed along with vaginal pulse amplitude and self-report measures of desire and arousal in response to sexual fantasy, visual sexual stimuli, and photos of men's faces. Self-reported arousal and desire were lower in the HSDD than the SF group, but only for women who were not using oral contraceptives. Relationships between hormones and sexual function differed depending on whether a woman was HSDD or not. In line with prior literature, FT was positively associated with physiological and subjective sexual arousal in the SF group. The HSDD women demonstrated the opposite pattern, in that FT was negatively associated with subjective sexual responsiveness. The findings suggest a possible alternative relationship between hormones and sexual responsiveness in women with HSDD who have characteristics similar to those in the present study. PMID:21514299

    Objective To equip public health nurses (PHNs) with higher qualifications, PHN education is shifting from an integrated curriculum for PHNs and registered nurses to a specific elective system of undergraduate or postgraduate programs. Most colleges in the special wards of Tokyo introduced the elective system in 2014 before the remaining areas. The outcomes of this must be evaluated. This study aimed to evaluate the achievement levels and practical experiences of PHN students at seven colleges in the special wards before and after introduction of the PHN course as an elective.Method Self-administered, anonymous questionnaires were completed by senior PHN students at seven colleges in the special wards who underwent training in 2013, the last year of an integrated curriculum, and in 2014, the first year of the elective system. The target numbers of participants were 663 in 2013 and 136 in 2014 with 20 students from each school exposed to the elective system. Our study focused on whether they achieved the 98 "technical items of PHN training and achievement levels at the time of graduation" required by the Ministry of Health, Labour and Welfare. The study also determined whether participants obtained practical experience in 15 items developed by the special wards based on the standards set for training.Results In 2013, there were 348 total responses (52.5%) and 310 valid responses. In 2014, there were 136 total responses (88.2%) and 120 valid responses. The average achievement rate at which the student answered, "I was able to arrive at it," at an arrival degree level for the 98 technical items was 72.6% in 2014, an increase compared to the 67.9% obtained in 2013. Moreover, the average practical experience rate at which the student answered, "I was able to have an experience," regarding the 15 items was 85.7% in 2014, which constituted an increase compared to 70.5% attained in 2013. However, the number of items with an achievement rate of more than 80% remained

    Inhibited sexual desire (ISD) is one of the most common sexual dysfunctions, especially in women. Family physicians have an opportunity to recognize ISD before the associated problems become entrenched, and to guide couples toward satisfactory resolution. A summary is presented of current thinking on ISD and its causes. Case reports and observations about frequency of and treatment for ISD are included. Much less has been written about sexual avoidance in the presence of desire. A definition is offered of simple sexual avoidance in the absence of genital dysfunction. Frequency, treatment response, and specific cases are described. A newly identified entity—mutual unwillingness to importune for sex—is discussed briefly. Counselling which focuses on communication, self responsibility, and sex education is very helpful to patients with sexual problems. PMID:21274060

    We investigated telephone administration of the Children's Social Desirability (CSD) scale and our adaptation for children of the Social Desirability for Food scale (C-SDF). Each of 100 4th-graders completed 2 telephone interviews 28 days apart. CSD scores had adequate internal consistency and test—retest reliability, and a 14-item subset was identified that sufficiently measures the same construct. Our C-SDF scale performed less well in terms of internal consistency and test—retest reliability; factor analysis revealed 2 factors, 1 of which was moderately related to the CSD. The 14-item subset of the CSD scale may help researchers understand error in children's dietary reports. PMID:15068757

In the present study, participants completed measures of self-consciousness, social anxiety, self-esteem, and social desirability, using either the World-Wide Web (WWW) or pen and paper, and were assigned to either an anonymous or a nonanonymous condition. It was found that people reported lower social anxiety and social desirability and higher self-esteem when they were anonymous than when they were nonanonymous. Furthermore, participants also reported lower social anxiety and social desirability when they were using the Internet than when they were using paper-based methods. Contrast analyses supported the prediction that participants using the WWW anonymously would show the lowest levels of social desirability, whereas participants answering with pen and paper nonanonymously would score highest on the same measure. Implications for the use of the Internet for the collection of psychological data are discussed. PMID:10502866

    In relation with a recent Cochrane review, the paper discusses desirable features of a "humanoid" robot-therapist: 1) high mechanical compliance, 2) large range of force, 3) minimum assistance level, 4) soft haptic interaction for proprioceptive awareness, 5) adaptative assistance properties. It also proposes a framework for addressing optimal assistance and learning paradigms in view of a consensus in the community of rehabilitation engineers about shared principles and common standards.

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

    We evaluated the clinical efficacy and safety of teicoplanin according to the pharmacokinetics (PK) therapeutic level achieved in patients with renal dysfunction. Target trough concentration (Cmin) was ≥15-30 μg/ml which has been recommended in patients with normal renal function. Adult patients (estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2)) who were treated by teicoplanin were included in the study. We adopted two types of regimen for the initial 3 days: the conventional regimen, and the enhanced loading regimen (10 mg/kg twice daily on the 1st day, followed by 6.7-10 mg/kg once daily for the 2nd and 3rd days]. Two hundred and eighty-eight patients were evaluated for safety, and 106 patients with methicillin-resistant Staphylococcus aureus (MRSA) infections were evaluated for clinical efficacy. A significantly higher success rate was obtained in patients who achieved the target initial Cmin compared with those that did not (75.0 % vs 50.0 %, p = 0.008). In a multivariate analysis, initial Cmin ≥15 μg/ml was an independent factor for clinical success (adjusted odds ratio: 4.20, 95 % confidence interval: 1.34-13.15). In patients with 15-30 μg/ml of maximal Cmin during therapy, nephrotoxicity occurred in 13.1 %, and hepatotoxicity in 2.6 %, and these incidences were not significantly higher compared with those patients with <15 μg/ml. In conclusion, achievement of Cmin of 15-30 μg/ml without delay was necessary to improve clinical outcomes for the treatment by teicoplanin in patients with renal dysfunction. Further investigation is required regarding the optimal loading regimen to achieve the therapeutic levels in those patients. PMID:27278654

    This paper reports the effects of a comprehensive elementary school-based social-emotional and character education program on school-level achievement, absenteeism, and disciplinary outcomes utilizing a matched-pair, cluster randomized, controlled design. The Positive Action Hawai‘i trial included 20 racially/ethnically diverse schools (mean enrollment = 544) and was conducted from the 2002-03 through the 2005-06 academic years. Using school-level archival data, analyses comparing change from baseline (2002) to one-year post trial (2007) revealed that intervention schools scored 9.8% better on the TerraNova (2nd ed.) test for reading and 8.8% on math; 20.7% better in Hawai‘i Content and Performance Standards scores for reading and 51.4% better in math; and that intervention schools reported 15.2% lower absenteeism and fewer suspensions (72.6%) and retentions (72.7%). Overall, effect sizes were moderate to large (range 0.5-1.1) for all of the examined outcomes. Sensitivity analyses using permutation models and random-intercept growth curve models substantiated results. The results provide evidence that a comprehensive school-based program, specifically developed to target student behavior and character, can positively influence school-level achievement, attendance, and disciplinary outcomes concurrently.

    This news brief presents findings from a survey of fertility desires among 10,000 farm households in 1400 villages, 140 townships, and 14 counties in Hunan Province, China. Findings reveal that farmers fully support the present national family planning program. Farmers believe that smaller families will contribute to higher incomes and improvement in people's lives. 1.51% of farmers were dissatisfied with the family planning program, and 2.48% desired more children. During 1982 to the present, the average number of births in Huanglongxincum Village, Huanghua Town, Changsha County, declined from 76 to 26 births. The average net per capita income increased from 100 yuan to 3000 yuan. Five couples with only daughters declined the offer of second birth quotas. A woman from Shou Hongsheng, Heliao Township, Zhigiang County, had an only daughter and left with her family for another village in 1991 with the hope of having a second child. Instead the couple prospered, and net annual family income from a specialized fruit production business increased to 40,000 yuan yearly. By 1994, the couple was given permission to have a second child, but the couple turned down the offer. Local provincial family planning officials believe these changes in attitude among farmers are a hopeful sign and the highest award given by the people to the public sector. PMID:12347489

    We developed a head-mounted display (HMD) that achieved high levels of color uniformity and optical efficiency. The full-color holographic volume grating (HVG) attached on the specially designed wedge-shaped waveguide HMD system provided a 17° horizontal field of view (FOV). Theoretical analyses showed that the proposed waveguide resolved the problems of thickness and limited FOV. In this system, the HVG was recorded using a special sequential recording process on single photopolymer unit with 633, 532, and 473 nm wavelengths. The results confirm that the designed and fabricated waveguide can be employed in future commercial HMS. PMID:24787179

    The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in the Mixed-Humid Climate Region on a cost-neutral basis.

    In order to reduce costs and achieve schedules for Closure of the Rocky Flats Environmental Technology Site (RFETS), the Waste Requirements Group has implemented a number of cost saving initiatives aimed at integrating waste volume reduction with the selection of compliant waste packaging methods for the disposal of RFETS low level radioactive waste (LLW). Waste Guidance Inventory and Shipping Forecasts indicate that over 200,000 m3 of low level waste will be shipped offsite between FY2002 and FY2006. Current projections indicate that the majority of this waste will be shipped offsite in an estimated 40,000 55-gallon drums, 10,000 metal and plywood boxes, and 5000 cargo containers. Currently, the projected cost for packaging, shipment, and disposal adds up to $80 million. With these waste volume and cost projections, the need for more efficient and cost effective packaging and transportation options were apparent in order to reduce costs and achieve future Site packaging a nd transportation needs. This paper presents some of the cost saving initiatives being implemented for waste packaging at the Rocky Flats Environmental Technology Site (the Site). There are many options for either volume reduction or alternative packaging. Each building and/or project may indicate different preferences and/or combinations of options.

Sildenafil citrate (Viagra) and Tadalafil (Cialis), which have been prescribed for male sexual function disorders, are known to act on vessels.[1] On the other hand, flibanserin is thought to act on brain. Flibanserin has been approved by U. S. Food and Drug Administration (FDA) for treatment of hypoactive sexual desire disorder (HSDD) of premenopausal women in 2015, and is expected to be released in South Korea soon. Authors wrote this article to acknowledge flibanserin to sexologists for females or physicians for menopausal medicine, so that this agent can be safely used for females who have HSDD. PMID:27152308

    This paper reviews recent advances in telecommunications and examines the detailed structure of travel to estimate the feasibility of substituting telecommunications for various travel objectives. The impact of travel is analyzed from a social, economic, energy, and pollution standpoint to assess the desirability of substitution. Perhaps 35-50% of the nation's travel could, in theory, be replaced by very advanced telecommunications (such as a much improved large-screen teleconferencing network), but public resistance would be massive. Much economic dislocation would result since, for example, over 25% of retail sales are travel-related. The energy savings would be modest since only 25% of the nation's energy is consumed by transportation. However, all pollution would be reduced substantially since transportation accounts for 75% of the carbon monoxide, 60% of the hydrocarbon, and 55% of the nitrogen oxide pollution in the nation. Problems related to the implementation of large-scale substitution are discussed.

    Women are underrepresented in most high-level positions in organizations. Though a great deal of research has provided evidence that bias and discrimination give rise to and perpetuate this gender disparity, in the current research we explore another explanation: men and women view professional advancement differently, and their views affect their decisions to climb the corporate ladder (or not). In studies 1 and 2, when asked to list their core goals in life, women listed more life goals overall than men, and a smaller proportion of their goals related to achieving power at work. In studies 3 and 4, compared to men, women viewed high-level positions as less desirable yet equally attainable. In studies 5-7, when faced with the possibility of receiving a promotion at their current place of employment or obtaining a high-power position after graduating from college, women and men anticipated similar levels of positive outcomes (e.g., prestige and money), but women anticipated more negative outcomes (e.g., conflict and tradeoffs). In these studies, women associated high-level positions with conflict, which explained the relationship between gender and the desirability of professional advancement. Finally, in studies 8 and 9, men and women alike rated power as one of the main consequences of professional advancement. Our findings reveal that men and women have different perceptions of what the experience of holding a high-level position will be like, with meaningful implications for the perpetuation of the gender disparity that exists at the top of organizational hierarchies.

    The Sleeping Beauty (SB) transposon system has been shown to enable long-term gene expression by integrating new sequences into host cell chromosomes. We found that the recently reported SB100x hyperactive transposase conferred a surprisingly high level of long-term expression after hydrodynamic delivery of luciferase-encoding reporter transposons in the mouse. We conducted dose-ranging studies to determine the effect of varying the amount of SB100x transposase-encoding plasmid (pCMV-SB100x) at a set dose of luciferase transposon and of varying the amount of transposon-encoding DNA at a set dose of pCMV-SB100x in hydrodynamically injected mice. Animals were immunosuppressed using cyclophosphamide in order to prevent an antiluciferase immune response. At a set dose of transposon DNA (25 µg), we observed a broad range of pCMV-SB100x doses (0.1-2.5 µg) conferring optimal levels of long-term expression (>10(11) photons/second/cm(2)). At a fixed dose of 0.5 μg of pCMV-SB100x, maximal long-term luciferase expression (>10(10) photons/second/cm(2)) was achieved at a transposon dose of 5-125 μg. We also found that in the linear range of transposon doses (100 ng), co-delivering the CMV-SB100x sequence on the same plasmid was less effective in achieving long-term expression than delivery on separate plasmids. These results show marked flexibility in the doses of SB transposon plus pCMV-SB100x that achieve maximal SB-mediated gene transfer efficiency and long-term gene expression after hydrodynamic DNA delivery to mouse liver.

    A large body of literature demonstrates that East Asian women report lower sexual desire than Caucasian women. Although most studies have explained these differences by referring to general culture-linked differences in sexual conservatism, none have examined the potential role of specific constructs such as sex guilt. The goals of the current study were to examine the supposition that sexual conservatism mediates the relationship between culture and sexual desire, and to explore the potential mediating role of sex guilt in the link between culture and sexual desire. Caucasian (n = 105) and East Asian (n = 137) female university students completed questionnaires online. Caucasian women reported significantly higher levels of sexual desire, significantly lower levels of sexual conservatism, and significantly less sex guilt. In the entire sample, sexual conservatism and sex guilt separately mediated the relationship between ethnicity and sexual desire such that women with more sex guilt and those who were more sexually conservative reported lower sexual desire. Among the East Asian women, sex guilt, but not sexual conservatism, mediated the relationship between mainstream acculturation (degree of westernization) and sexual desire such that women with more sex guilt reported lower sexual desire. These findings suggest that sex guilt may be one mechanism by which ethnic groups differ in sexual desire. PMID:20349208

    With the increase of the student population, and meeting the demands driven by society public schools are scrambling to find ways to enhance learning and improve student achievement (Lee, 1993). Schools are examining and investing more time in the development of new approaches needed to strengthen, reach, and spark the interest of students both in and outside of classroom. One direction public schools are taking is to incorporate technology and more peer-directed group activities into instruction. Technological advancements today have enhanced the learning process by providing alternatives that stimulate the interest of the learner. Having these technology options available, allows the student to move at his or her own pace giving them time to reflect and make connections between what they already know and what they have learned in class. Using the conceptual framework of the Studio Model, which was developed in the 1980s at Rensselaer Polytechnic Institute for undergraduate and graduate level science courses, this study investigated the nature and extent to which the components in the Studio Model (cooperative collaboration and online materials) can be extended to the high school science level. A quasi-experimental, pretest-posttest design was selected for this study. Classes were randomly assigned to one of the four treatment groups, an experimental "Studio Model" condition in which students worked cooperatively and had access to online materials, an "Augmented Only" condition in which students had access to online materials only, a "Cooperative Only" condition in which students worked in cooperative groups only, and a "Control" condition in which students neither had access to online materials nor worked cooperatively. The data was collected for this study using 77 ninth-grade students studying Earth Science. Students were trained for a period of 20 weeks in the procedures of their particular treatment.

    Objective To examine test-retest reliability and internal consistency of the Children’s Social Desirability Short (S-CSD) scale, consisting of 14 items from the Children’s Social Desirability scale. Methods The previously validated S-CSD scale was classroom administered to 97 fourth-grade children (80% African American, 76% low socioeconomic status) in 2 sessions a month apart. Each classroom administration lasted approximately 5 minutes. Results The S-CSD scale showed acceptable levels of test-retest reliability (0.70) and internal consistency (0.82 and 0.85 for the first and second administrations, respectively). Reliability was adequate within subgroups of gender, socioeconomic status, academic achievement, and body mass index percentile. Levels of social desirability did not differ across subgroups. Conclusions and Implications Social desirability bias is a potential source of systematic response error in children’s self-report assessments of nutrition and health-related behaviors. The S-CSD scale may be used with diverse groups of children to reliably and efficiently assess social desirability bias. PMID:24418615

    NASA is currently developing the next generation crewed spacecraft and launch vehicle for exploration beyond earth orbit including returning to the Moon and making the transit to Mars. Managing the design integration of major hardware elements of a space transportation system is critical for overcoming both the technical and programmatic challenges in taking a complex system from concept to space operations. An established method of accomplishing this is formal interface management. In this paper we set forth an argument that the interface management process implemented by NASA between the Orion Multi-Purpose Crew Vehicle (MPCV) and the Space Launch System (SLS) achieves the Level 3 tier of the EIA 731.1 System Engineering Capability Model (SECM) for Generic Practices. We describe the relevant NASA systems and associated organizations, and define the EIA SECM Level 3 Generic Practices. We then provide evidence for our compliance with those practices. This evidence includes discussions of: NASA Systems Engineering Interface (SE) Management standard process and best practices; the tailoring of that process for implementation on the Orion to SLS interface; changes made over time to improve the tailored process, and; the opportunities to take the resulting lessons learned and propose improvements to our institutional processes and best practices. We compare this evidence against the practices to form the rationale for the declared SECM maturity level.

    The assessment of personality is recognized by space agencies as an approach to identify candidates likely to perform optimally during spaceflights. In the use of personality scales for selection, the impact of social desirability (SD) has been cited as a concern. Study 1 addressed the impact of SD on responses to the Personality Characteristic Inventory (PCI) and NEO-FFI. This was achieved by contrasting scores from active astronauts (N=65) with scores of successful astronaut applicants (N=63), and between pilots applicants (N=1271) and pilot research subjects (N=120). Secondly, personality scores were correlated with scores on the Marlow Crown Social Desirability Scale among applicants to managerial positions (N=120). The results indicated that SD inflated scores on PCI scales assessing negative interpersonal characteristics, and impacted on four of five scales in NEO-FFI. Still, the effect sizes were small or moderate. Study 2 addressed performance implications of SD during an assessment of males applying to work as rescue personnel operations in the North Sea (N=22). The results showed that SD correlated negatively with cognitive test performance, and positively with discrepancy in performance ratings between self and two observers. In conclusion, caution is needed in interpreting personality scores in applicant populations. SD may be a negative predictor for performance under stress.

    Mapping degradation and conservation in the DESIRE Project The World Overview of Conservation Approaches and Technologies initiative (WOCAT) started in 1992, in reaction to the Global Assessment of Soil Degradation (GLASOD) by ISRIC. The original idea of WOCAT was to develop a world map similar the GLASOD one, however showing the positive side, i.e. describing what achievements had been made to combat soil degradation. Since 1992 WOCAT has developed and tested a method for standardized documentation and evaluation of Sustainable Land Management (SLM). It comprises three questionnaires, for documenting "Technologies" (what is actually implemented in the field), "Approaches" (what is needed in terms of "enabling environment" for a successful implementation of a technology) and a mapping questionnaire. The resulting database currently counts more than 350 technologies and over 250 approaches from around 50 countries. In the DESIRE project the WOCAT mapping tool was used to map area coverage, degree, impact, effectiveness, and other parameters of land degradation and conservation for 16 study sites. The mapping method in the study sites complements the information provided by the individual case studies on technologies and Approaches. It evaluates what type of land degradation is actually happening where and what is done about it in terms of Sustainable Land Management (SLM). The on-line map database is hosted by WOCAT, and the mapped outputs that can be generated from this database provide a powerful tool to obtain an overview of land degradation and conservation in a country, a region, or worldwide.

In conclusion, caution is needed in interpreting personality scores in applicant populations. SD maybe a negative predictor for performance under stress. PMID:16010763

    Liquid epoxy resin impregnation systems remain a state-of-the-art polymer material for vacuum and vacuum/pressure impregnation applications in the manufacture of both advanced and conventional coil winding configurations. Epoxy resins inherent latitude in processing parameters accounts for their continued popularity in engineering applications, but also for the tendency to overlook or misinterpret the requisite processing parameters on the manufacturing floor. Resin system impregnation must be managed in detail in order to achieve device life cycle reliability. This closer look reveals how manufacturing floor level management of material acceptance, handling and storage, pre- and post- impregnation processing and cure can be built into a manufacturing plan to increase manufacturing yield, lower unit cost and ensure optimum life cycle performance of the coil.

  15. Influence of social desirability on age differences in self-reports of mood and personality.

    ABSTRACT Increased age has been found to be associated with differences in affect and personality that have been interpreted in terms of better emotional regulation and increased maturity. However, these findings have largely been based on self-report data, and the primary goal of the current research was to investigate the hypothesis that age-related differences in affect and in certain desirable personality traits might, at least partially, reflect age differences in social desirability. As expected, increased age was associated with lower levels of negative affect and Neuroticism and higher levels of positive affect, life satisfaction, Agreeableness, and Conscientiousness, and scores on the social desirability scale were positively related to age and to desirable self-report characteristics but negatively related to undesirable self-report characteristics. Importantly, controlling for the variance in the social desirability measure resulted in less positive age trends in both types of self-report measures. PMID:21682727

    The Minimum Variance Lower Bound (MVLB) represents the best achievable controller capability in a variance sense. Estimation and realization of MVLB for nonlinear systems confront some difficulties. Hence, almost all methods introduced so far estimate MVLB for a certain structure (e.g., NARMAX) or controller (e.g. PID). In this paper, MVLB for desired structures (not restricted to a certain type) is studied. The situation when the model is not in hand, is not accurate, or is not invertible has been considered. Moreover, in order to realize minimum variance controllers for nonlinear structures, a recursive model-free MVC design is utilized. Finally, a simulation study has been used to clarify the effectiveness of the proposed control scheme. PMID:24642244

    Changes in gene expression are associated with switching to an autoprotected phenotype in response to environmental and physiological stress. Ubiquitous molecular chaperones from the heat shock protein (HSP) superfamily confer neuronal protection that can be blocked by antibodies. Recent research has focused on the interactions between the molecular sensors that affect the increased expression of neuroprotective HSPs above constitutive levels. An examination of the conditions under which the expression of heat shock protein 70 (Hsp70) was up regulated in a hypoxia and anoxia tolerant tropical species, the epaulette shark (Hemiscyllium ocellatum), revealed that up-regulation was dependent on exceeding a stimulus threshold for an oxidative stressor. While hypoxic-preconditioning confers neuroprotective changes, there was no increase in the level of Hsp70 indicating that its increased expression was not associated with achieving a neuroprotected state in response to hypoxia in the epaulette shark. Conversely, there was a significant increase in Hsp70 in response to anoxic-preconditioning, highlighting the presence of a stimulus threshold barrier and raising the possibility that, in this species, Hsp70 contributes to the neuroprotective response to extreme crises, such as oxidative stress. Interestingly, there was a synergistic effect of coincident stressors on Hsp70 expression, which was revealed when metabolic stress was superimposed upon oxidative stress. Brain energy charge was significantly lower when adenosine receptor blockade, provided by treatment with aminophylline, was present prior to the final anoxic episode, under these circumstances, the level of Hsp70 induced was significantly higher than in the pair-matched saline treated controls. An understanding of the molecular and metabolic basis for neuroprotective switches, which result in an up-regulation of neuroprotective Hsp70 expression in the brain, is needed so that intervention strategies can be devised

    Objectives To describe the prospects, achievements, challenges and opportunities for implementing intermittent preventive treatment for malaria in pregnancy (IPTp) in Tanzania in light of national antenatal care (ANC) guidelines and ability of service providers to comply with them. Methods In-depth interviews were made with national level malaria control officers in 2006 and 2007. Data was analysed manually using a qualitative content analysis approach. Results IPTp has been under implementation countrywide since 2001 and the 2005 evaluation report showed increased coverage of women taking two doses of IPTp from 29% to 65% between 2001 and 2007. This achievement was acknowledged, however, several challenges were noted including (i) the national antenatal care (ANC) guidelines emphasizing two IPTp doses during a woman's pregnancy, while other agencies operating at district level were recommending three doses, this confuses frontline health workers (HWs); (ii) focused ANC guidelines have been revised, but printing and distribution to districts has often been delayed; (iii) reports from district management teams demonstrate constraints related to women's late booking, understaffing, inadequate skills of most HWs and their poor motivation. Other problems were unreliable supply of free SP at private clinics, clean and safe water shortage at many government ANC clinics limiting direct observation treatment and occasionally pregnant women asked to pay for ANC services. Finally, supervision of peripheral health facilities has been inadequate and national guidelines on district budgeting for health services have been inflexible. IPTp coverage is generally low partly because IPTp is not systematically enforced like programmes on immunization, tuberculosis, leprosy and other infectious diseases. Necessary concerted efforts towards fostering uptake and coverage of two IPTp doses were emphasized by the national level officers, who called for further action including operational

    The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in the Hot-Dry/Mixed-Dry Climate Region on a cost neutral basis.

  4. FcRn binding is not sufficient for achieving systemic therapeutic levels of immunoglobulin G after oral delivery of enteric-coated capsules in cynomolgus macaques.

    Although much speculation has surrounded intestinally expressed FcRn as a means for systemic uptake of orally administered immunoglobulin G (IgG), this has not been validated in translational models beyond neonates or in FcRn-expressing cells in vitro. Recently, IgG1 intestinal infusion acutely in anesthetized cynomolgus resulted in detectable serum monoclonal antibody (mAb) levels. In this study, we show that IgG2 has greater protease resistance to intestinal enzymes in vitro and mice in vivo, due to protease resistance in the hinge region. An IgG2 mAb engineered for FcRn binding, was optimally formulated, lyophilized, and loaded into enteric-coated capsules for oral dosing in cynomolgus. Small intestinal pH 7.5 was selected for enteric delivery based on gastrointestinal pH profiling of cynomolgus by operator-assisted IntelliCap System(®). Milling of the lyophilized IgG2 M428L FcRn-binding variant after formulation in 10 mmol/L histidine, pH 5.7, 8.5% sucrose, 0.04% PS80 did not alter the physicochemical properties nor the molecular integrity compared to the batch released in PBS. Size 3 hard gel capsules (23.2 mg IgG2 M428L ~3 mg/kg) were coated with hydroxypropyl methylcellulose acetate succinate for rapid dissolution at pH 7.5 in small intestine and FcRn binding of encapsulated mAb confirmed. Initial capsule dosing by endoscopic delivery into the small intestine achieved 0.2 + 0.1 ng/mL (n = 5) peak at 24 h. Weekly oral capsule dosing for 6 weeks achieved levels of 0.4 + 0.2 ng/mL and, despite increasing the dose and frequency, remained below 1 ng/mL. In conclusion, lyophilized milled mAb retains FcRn binding and molecular integrity for small intestinal delivery. The low systemic exposure has demonstrated the limitations of intestinal FcRn in non-human primates and the unfeasibility of employing this for therapeutic levels of mAb. Local mAb delivery with limited systemic exposure may be sufficient as a therapeutic for intestinal diseases. PMID

    CEA-Leti MINATEC has been involved in infrared focal plane array (IRFPA) development since many years, with performing HgCdTe in-house process from SWIR to LWIR and more recently in focusing its work on new ROIC architectures. The trend is to integrate advanced functions into the CMOS design for the purpose of applications demanding a breakthrough in Noise Equivalent Temperature Difference (NETD) performances (reaching the mK in LWIR band) or a high dynamic range (HDR) with high-gain APDs. In this paper, we present a mid-TV format focal plane array (FPA) operating in LWIR with 25μm pixel pitch, including a new readout IC (ROIC) architecture based on pixel-level charge packets counting. The ROIC has been designed in a standard 0.18μm 6-metal CMOS process, LWIR n/p HgCdTe detectors were fabricated with CEA-Leti in-house process. The FPA operates at 50Hz frame rate in a snapshot integrate-while-read (IWR) mode, allowing a large integration time. While classical pixel architectures are limited by the charge well capacity, this architecture exhibits a large well capacity (near 3Ge-) and the 15-bit pixel level ADC preserves an excellent signal-to-noise ratio (SNR) at full well. These characteristics are essential for LWIR FPAs as broad intra-scene dynamic range imaging requires high sensitivity. The main design challenges for this digital pixel array (SNR, power consumption and layout density) are discussed. The electro-optical results demonstrating a peak NETD value of 2mK and images taken with the FPA are presented. They validate both the pixel-level ADC concept and its circuit implementation. A previously unreleased SNR of 90dB is achieved.

  6. Why Indexing the Sky is Desirable

    Ortiz, P. F.

    Indexing the sky is a database-oriented term to indicate a partitioning scheme of the celestial sphere in order to achieve better performance in queries involving finding close neighbours. Several schemes have been proposed: HTM, HEALPix, ``IDT: iso-declination tiles", Quadrilateralized Spherical Cube, etc., but their use has not become widespread. The scientific value of the internal indexation files is much higher though, as they keep track of the source density of catalogues and hence allow us to answer a family of questions not easily handled by a standard DB system and providing an unusual visual aid: a snapshot of the location of sources listed in any catalog. The pros and cons of adopting an VO-oriented indexation scheme are analyzed.

    Latino male bisexuality has been studied for the most part with a focus on men who have sex with men (MSM) and with little attention to sexual desire. The goal of this article is to present a comprehensive understanding of how sexual desire is organized, enacted through sexual activity, and interpreted in the sexual lives of bisexually-active Latino men. To achieve this aim, an analysis was made of 18 sexual histories of bisexually active Latino men who participated in a two-year ethnographic study. Four configurations of sexual desire were constructed to reflect what was found in this population of bisexually-active Latino men: (a) lifetime homoerotic desire and casual sex with women; (b) lifetime heteroerotic desire, but commercial sex with men; (c) lifetime heteroerotic/transgender desire; (d) lifetime sexual desire for women and men. These configurations are explored in detail in this article. The analysis presented here is intended to offer insights into the overall study of Latino male bisexuality and into the foundations for the design of HIV and STI prevention programs directed toward bisexually-active Latino men and their partners.

    Work describe in this report represents the final year activities for the 3-year International Nuclear Energy Research Initiative (I-NERI) project: Development and Characterization of New High-Level Waste Forms for Achieving Waste Minimization from Pyroprocessing. Used electrorefiner salt that contained actinide chlorides and was highly loaded with surrogate fission products was processed into three candidate waste forms. The first waste form, a high-loaded ceramic waste form is a variant to the CWF produced during the treatment of Experimental Breeder Reactor-II used fuel at the Idaho National Laboratory (INL). The two other waste forms were developed by researchers at the Korean Atomic Energy Research Institute (KAERI). These materials are based on a silica-alumina-phosphate matrix and a zinc/titanium oxide matrix. The proposed waste forms, and the processes to fabricate them, were designed to immobilize spent electrorefiner chloride salts containing alkali, alkaline earth, lanthanide, and halide fission products that accumulate in the salt during the processing of used nuclear fuel. This aspect of the I-NERI project was to demonstrate 'hot cell' fabrication and characterization of the proposed waste forms. The outline of the report includes the processing of the spent electrorefiner salt and the fabrication of each of the three waste forms. Also described is the characterization of the waste forms, and chemical durability testing of the material. While waste form fabrication and sample preparation for characterization must be accomplished in a radiological hot cell facility due to hazardous radioactivity levels, smaller quantities of each waste form were removed from the hot cell to perform various analyses. Characterization included density measurement, elemental analysis, x-ray diffraction, scanning electron microscopy and the Product Consistency Test, which is a leaching method to measure chemical durability. Favorable results from this demonstration project

  13. The taming of desire: Unspecific postponement reduces desire for and consumption of postponed temptations.

    PubMed

    Mead, Nicole L; Patrick, Vanessa M

    2016-01-01

    The present investigation began with the conjecture that people may do better by saying "some other time" instead of "no, not ever" in response to temptations. Drawing from learning theories, we hypothesized that people interpret unspecific postponement ("I can have it some other time") as a signal that they do not strongly value the postponed temptation. In this way, unspecific postponement may reduce desire for and consumption of postponed temptations, both in the present moment and over time. Four experiments tested those hypotheses. A multiphase study using the free-choice paradigm supported the learning account for the effects of postponement: unspecific postponement reduced immediate desire for a self-selected temptation which in turn statistically accounted for diminished consumption during the week after the manipulation--but only when postponement was induced, not when it was imposed (Experiment 1). Supporting the hypothesis that unspecific but not specific postponement connotes weak valuation, only unspecific postponement reduced attention to (Experiment 2) and consumption of (Experiment 3) the postponed temptation. Additionally, unspecific postponement delayed consumption primarily among those who were highly motivated to forgo consumption of the temptation (Experiment 3). A final multiphase experiment compared the effectiveness of unspecific postponement to the classic self-control mechanism of restraint, finding that unspecific postponement (vs. restraint) reduced consumption of the temptation in the heat of the moment and across 1 week postmanipulation (Experiment 4). The current research provides novel insight into self-control facilitation, the modification of desire, and the differential effects of unspecific and specific intentions for reducing unwanted behavior.

  15. Testosterone and sexual desire in healthy women and men.

    PubMed

    van Anders, Sari M

    2012-12-01

    Sexual desire is typically higher in men than in women, with testosterone (T) thought to account for this difference as well as within-sex variation in desire in both women and men. However, few studies have incorporated both hormonal and social or psychological factors in studies of sexual desire. The present study addressed how three psychological domains (sexual-relational, stress-mood, body-embodiment) were related to links between T and sexual desire in healthy adults and whether dyadic and solitary desire showed associations with T. Participants (n = 196) were recruited as part of the Partnering, Physiology, and Health study, which had 105 men and 91 women who completed questionnaires and provided saliva for cortisol and T assays. T was positively linked to solitary desire in women, with masturbation frequency influencing this link. In contrast, T was negatively correlated with dyadic desire in women, but only when cortisol and perceived social stress were controlled. Replicating past findings, no significant correlations between T and desire in men were apparent, but these analyses showed that the null association remained even when psychological and confound variables were controlled. Men showed higher desire than women, but masturbation frequency rather than T influenced this difference. Results were discussed in terms of challenges to assumptions of clear links between T and desire, gendered approaches to T, and the unitarity of desire. PMID:22552705

    2004-08-01

    This article reports the utility of an information processing approach to examine whether there is a relationship between sexual content induced delay and levels of sexual desire as determined by self-report questionnaires. We tested this idea using a partial replication of the J. H. Geer and H. S. Bellard (1996) protocol demonstrating sexual content induced delay (SCID) in responding to sexual versus neutral words. In addition, the experiment examined whether SCID was different in people with varying levels of sexual desire. It was hypothesized that persons with low levels of sexual desire might respond more slowly to sexual word cues than others. Words with equal frequency of usage and similar word length were chosen from among those used in the Geer and Bellard study. The experiment was conducted with 171 volunteers who completed sexual desire questionnaires, lexical decision making tasks, and word ratings. The SCID effect was demonstrated by both men and women in the study with no significant variation between the sexes. In accordance with prediction, it was found that persons with lower levels of sexual desire responded more slowly to sexual stimuli than other participants, and rated sexual words as less familiar, less acceptable, and less positive emotionally to them. These findings have implications for understanding how emotional content contributes to SCID. They also suggest that further exploration of these ideas, perhaps using other stimulus modalities, may be helpful in advancing understanding of responses to sexual cues, and the potential implications that may have in better understanding sexual desire.

  4. Long distance atomic teleportation with as good success as desired

    2015-09-15

    Long distance atomic teleportation (LDAT) is of prime importance in long distance quantum communication. Scheme proposed by Bose et al. (1999) in principle enables us to have LDAT using cavity decay. However it gives message state dependent fidelity and success rate. Here, using interaction of entangled coherent states with atom–cavity systems and a two-step measurement, we show how, LDAT can be achieved with unit fidelity and as good success as desired under ideal conditions. The scheme is unique in that, the first measurement predicts success or failure. If success is predicted then second measurement gives perfect teleportation. If failure is predicted the message-qubit remains conserved therefore a second attempt may be started. We found that even in presence of decoherence due to dissipation of energy our scheme gives message state independent success rate and almost perfect teleportation in single attempt with mean fidelity of teleportation equal to 0.9 at long distances. However if first attempt fails, unlike ideal case where message-qubit remains conserved with unit fidelity, in presence of decoherence the message-qubit remains conserved to some degree, therefore mean fidelity of teleportation can be increased beyond 0.9 by repeating the process.

  5. Designing Vibrotactile Balance Feedback For Desired Body Sway Reductions

    Loughlin, Patrick; Mahboobin, Arash; Furman, Joseph

    2016-01-01

    Vibrotactile feedback about body position and velocity has been shown to be effective at reducing low frequency body sway (below about 0.5 Hz) in response to balance perturbations while standing. However, current devices cause an undesirable increase in high frequency body sway. In addition, unlike other sensory prostheses such as hearing aids, which are fine-tuned to the user, current vibrotactile balance prostheses largely employ a “one size fits all” approach, in that they use the same settings (i.e. parameter values) for all subjects. Rather than using a fixed design consisting of position and velocity feedback for all subjects, we propose a “custom design” approach that employs system identification methods to identify the feedback required to achieve a desired body sway frequency response for the subject. Our derivations and simulations show that in order to accomplish this objective, feedback consisting of a subject-specific filtered combination of body position, velocity and acceleration is required. Simulation results are provided to illustrate the results. PMID:22254557

  6. Children's understanding of the distinction between intentions and desires.

    Schult, Carolyn A

    2002-01-01

    Much of the previous research on children's understanding of intentions confounded intentions with desires. Intentions and desires are different, in that a desire can be satisfied in a number of ways, but an intention must be satisfied by carrying out the intended action. Children 3 through 7 years of age and adults were presented with situations in which intentions were satisfied but desires were not, or vice versa, in a story-comprehension task (N = 71) and a target-hitting game (N = 45). Although 3- and 4-year-olds were unable to differentiate desires and intentions consistently, 5- and 7-year-olds often matched the adult pattern. Younger children's difficulties in understanding intentions are discussed in terms of their use of a desire-outcome matching strategy and the representational complexities of intentions.

    Automatic exposure control (AEC) systems have been developed by computed tomography (CT) manufacturers to improve the consistency of image quality among patients and to control the absorbed dose. Since a multichannel helical CT scan may easily increase individual radiation doses, this technical improvement is of special interest in children who are particularly sensitive to ionizing radiation, but little information is currently available regarding the precise performance of these systems on small patients. Our objective was to assess an AEC system on pediatric dose phantoms by studying the impact of phantom transmission and acquisition parameters on tube current modulation, on the resulting absorbed dose and on image quality. We used a four-channel CT scan working with a patient-size and z-axis-based AEC system designed to achieve a constant noise within the reconstructed images by automatically adjusting the tube current during acquisition. The study was performed with six cylindrical poly(methylmethacrylate) (PMMA) phantoms of variable diameters (10-32 cm) and one 5 years of age equivalent pediatric anthropomorphic phantom. After a single scan projection radiograph (SPR), helical acquisitions were performed and images were reconstructed with a standard convolution kernel. Tube current modulation was studied with variable SPR settings (tube angle, mA, kVp) and helical parameters (6-20 HU noise indices, 80-140 kVp tube potential, 0.8-4 s. tube rotation time, 5-20 mm x-ray beam thickness, 0.75-1.5 pitch, 1.25-10 mm image thickness, variable acquisition, and reconstruction fields of view). CT dose indices (CTDIvol) were measured, and the image quality criterion used was the standard deviation of the CT number measured in reconstructed images of PMMA material. Observed tube current levels were compared to the expected values from Brooks and Di Chiro's [R.A. Brooks and G.D. Chiro, Med. Phys. 3, 237-240 (1976)] model and calculated values (product of a reference value

    Meyer, Patrick

    2016-03-16

    Hypoactive sexual desire disorder (HSDD) is a deficiency of sexual desire that causes marked personal or interpersonal distress. It occurs in approximately 1 in 10 adult women. A number of potential contributory factors (hormonal, neurobiological and psychosocial) have been identified. Testosterone plays an excitatory role in sexual desire but the mechanism is not yet well understood. Treatment with testosterone has been shown to improve sexual desire in menopausal women with HSDD. However, there are limited data concerning premenopausal women and long-term safety. At present, physiological testosterone preparations for use in women are not available in Switzerland.

    1997-01-01

    A commercial product, Libido (Libid, Libbido, Erosom and Ardorare, names used in different markets), which is based on components derived from fertilized, partly incubated chickens' eggs, has been used to treat diminished sexual desire in men. The results from two double-blind cross-over placebo-controlled experiments indicate that Libido has a significant enhancing effect on sexual desire in men with normal and reduced sexual drive. Over periods as short as 2 weeks, 58% of the participants with low sexual desire noticed improvement as assessed using a visual analogue scale. Data obtained from consumers suggest significant effects on the frequency of sexual intercourse, on increased self-esteem, on the level of happiness, and on stamina. In a separate Swedish study, 84% of 31 men reported increased sexual desire during 3 weeks on Libido. It takes 1-2 weeks of regular use of Libido (3 g twice daily) before noticeable changes are observed. PMID:9100160

  19. From desires to behavior: Moderating factors in a fertility transition

    Hayford, Sarah R.; Agadjanian, Victor

    2013-01-01

    BACKGROUND Extensive research in both developed and developing countries has shown that preferences and intentions for future childbearing predict behavior. However, very little of this research has examined high-fertility contexts in sub-Saharan Africa. In particular, the factors that increase or decrease correspondence between fertility desires and behavior in these settings are not well understood. OBJECTIVE This article documents the degree to which the desire to stop childbearing predicts fertility behavior over the short term among married women in rural southern Mozambique, a context where fertility transition is still in the early stages. Analyses test the moderating powers of individual, household, and community characteristics. METHODS Analyses use data from a longitudinal survey of married women of reproductive age (N=1678) carried out in 2006 and 2009 in rural areas of southern Mozambique. Logistic regression models are estimated to predict childbearing between 2006 and 2009 based on desires to stop childbearing and characteristics measured in 2006. RESULTS As expected, the desire to stop childbearing is strongly predictive of fertility behavior. Household wealth, local adult AIDS mortality, and being married to an unsuccessful labor migrant are associated with higher correspondence between reported desire to stop childbearing and fertility behavior. CONCLUSIONS Both factors related to the ability to carry out desires to stop childbearing and factors related to the strength and consistency of these desires moderate the association between desires and behaviors. Future research should expand measurement of fertility preferences to incorporate their strength and consistency as well as direction. PMID:23626485

    This study examines the effectiveness of bibliotherapy for low sexual desire among women, which is the most frequent sexual concern brought to counselors. Forty-five women responded to an advertisement for participation in a study on low sexual desire and were assigned to either the intervention or the wait-list control group. The intervention group completed the Hurlbert Index of Sexual Desire (HISD; Apt & Hurlbert, 1992) and the Female Sexual Function Index (FSFI; R. Rosen et al., 2000), read the self-help book under study in 6 weeks, and completed the measures a second time. The control group completed the same measures 6 weeks apart. Results demonstrated that the intervention group made statistically greater gains over time as compared with the control group on measures of sexual desire (HISD and FSFI Desire subscale), sexual arousal (FSFI Arousal subscale), sexual satisfaction (FSFI Satisfaction subscale), and overall sexual functioning (FSFI Total Score). A subset of participants in the intervention group participated in a 7-week follow-up study, and these participants maintained their gains in sexual desire and overall sexual functioning. Findings have important implications for future research on the efficacy of bibliotherapy generally and for low sexual desire specifically. Results also have vital implications for the treatment of low sexual desire. PMID:22774869

  4. Wishful seeing: more desired objects are seen as closer.

    PubMed

    Balcetis, Emily; Dunning, David

    2010-01-01

    Although people assume that they see the surrounding environment as it truly is, we suggest that perception of the natural environment is dependent upon the internal goal states of perceivers. Five experiments demonstrated that perceivers tend to see desirable objects (i.e., those that can fulfill immediate goals-a water bottle to assuage their thirst, money they can win, a personality test providing favorable feedback) as physically closer to them than less desirable objects. Biased distance perception was revealed through verbal reports and through actions toward the object (e.g., underthrowing a beanbag at a desirable object). We suggest that seeing desirable objects as closer than less desirable objects serves the self-regulatory function of energizing the perceiver to approach objects that fulfill needs and goals.

    2015-01-01

    The aim of this study is to estimate heritability of incident limitations on personally desired activities within the eighth decade of life. We measured self-rated ability to perform ten personally desired activities in 1606 male veteran twin pairs at baseline and four years later. At follow-up, 33% of the cohort reported more limitations in desired activities. Among twins who completed both assessments, there were no statistically significant differences in incidence rates of limitations as a function of zygosity. Sensitivity tests showed the same for change scores; and that, if cognitive impairment or death are deemed to belong among limitations of desired activities, zygosity contributed 10% to new limitations at follow-up. Maintaining personally desired activities over four years in the eighth decade is not subject to substantial genetic influence. However, if death and cognitive impairment are added to incident limitations, then genetics plays a modest role. In all cases, unique environment is the predominant influence. PMID:26973959

    PubMed Central

    Bäckström, Martin; Björklund, Fredrik

    2013-01-01

    An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects. PMID:23252410

  16. The ethical desirability of moral bioenhancement: a review of reasons

    PubMed Central

    2014-01-01

    Background The debate on the ethical aspects of moral bioenhancement focuses on the desirability of using biomedical as opposed to traditional means to achieve moral betterment. The aim of this paper is to systematically review the ethical reasons presented in the literature for and against moral bioenhancement. Discussion A review was performed and resulted in the inclusion of 85 articles. We classified the arguments used in those articles in the following six clusters: (1) why we (don’t) need moral bioenhancement, (2) it will (not) be possible to reach consensus on what moral bioenhancement should involve, (3) the feasibility of moral bioenhancement and the status of current scientific research, (4) means and processes of arriving at moral improvement matter ethically, (5) arguments related to the freedom, identity and autonomy of the individual, and (6) arguments related to social/group effects and dynamics. We discuss each argument separately, and assess the debate as a whole. First, there is little discussion on what distinguishes moral bioenhancement from treatment of pathological deficiencies in morality. Furthermore, remarkably little attention has been paid so far to the safety, risks and side-effects of moral enhancement, including the risk of identity changes. Finally, many authors overestimate the scientific as well as the practical feasibility of the interventions they discuss, rendering the debate too speculative. Summary Based on our discussion of the arguments used in the debate on moral enhancement, and our assessment of this debate, we advocate a shift in focus. Instead of speculating about non-realistic hypothetical scenarios such as the genetic engineering of morality, or morally enhancing ‘the whole of humanity’, we call for a more focused debate on realistic options of biomedical treatment of moral pathologies and the concrete moral questions these treatments raise.

  17. Evaluating the User Experience of Exercising Reaching Motions With a Robot That Predicts Desired Movement Difficulty.

    PubMed

    Shirzad, Navid; Van der Loos, H F Machiel

    2016-01-01

    The notion of an optimal difficulty during practice has been articulated in many areas of cognitive psychology: flow theory, the challenge point framework, and desirable difficulties. Delivering exercises at a participant's desired difficulty has the potential to improve both motor learning and users' engagement in therapy. Motivation and engagement are among the contributing factors to the success of exercise programs. The authors previously demonstrated that error amplification can be used to introduce levels of challenge into a robotic reaching task, and that machine-learning algorithms can dynamically adjust difficulty to the desired level with 85% accuracy. Building on these findings, we present the results of a proof-of-concept study investigating the impacts of practicing under desirable difficulty conditions. A control condition with a predefined random order for difficulty levels was deemed more suitable for this study (compared to constant or continuously increasing difficulty). By practicing the task at their desirable difficulties, participants in the experimental group perceived their performance at a significantly higher level and reported lower required effort to complete the task, in comparison to a control group. Moreover, based on self-reports, participants in the experimental group were willing, on average, to continue the training session for 4.6 more training blocks (∼45 min) compared to the control group's average. This study demonstrates the efficiency of delivering the exercises at the user's desired difficulty level to improve the user's engagement in exercise tasks. Future work will focus on clinical feasibility of this approach in increasing stroke survivors' engagement in their therapy programs. PMID:25945816

    2010-01-01

    Although researchers have related sexual desire in older women to quality-of-life variables such as overall physical health, well-being, and life satisfaction, little is known about the socio-cultural mechanisms that shape sexual desire in minority ethnic older women. We investigated this sexual variable among Mexican-American older women in a qualitative fashion. Date were collected from 25 community-dwelling women of Mexican descent (aged 59–89 years) using a semi-structured interview protocol and a grounded theory approach. We inquired about dimensions of sexual desire including sexual fantasies and the desire to engage in sexual activity within the context of several socio-cultural and health-related factors. Using content analysis, we were able to identify key themes differentiating among respondents’ levels of sexual desire and fantasies. These included the availability of a suitable partner, cultural and religious norms pertinent to women’s sexuality, stigma related to sexuality in older age, and health status. Traditional socio-cultural restrictions coupled with unmarried status and physical health problems emerged as critical issues associated with limited or no sexual fantasies and desire in our sample. Many respondents indicated that their sexual needs were unmet. PMID:20526982

  19. Desiring foods: Cultivating non-attachment to nourishment in Buddhist Sri Lanka.

    PubMed

    Van Daele, Wim

    2016-10-01

    Food and desire are intimately entangled whereby food becomes a core tool to manage desire in fashioning oneself as a morally virtuous person. This paper looks at the ways in which Buddhist texts conceptualize human interactions with food and formulate prescriptions on how to handle food as a means of developing an attitude of non-attachment that aids in achieving nirvana-the extinguishing of desire to get released from the cycle of death and rebirth. The particular texts-the Agañña Sutta, the Āhāra Patikūlasaññā, and the Vinaya Pitaka- discussed here exhibit an attitude of deep ambiguity towards food in its capacity to incite desire. On the one hand nutrition is required to maintain life, but on the other, food can potentially be the cause of a degenerate state of mankind and a source of moral degradation. Hence, the Buddhist development of a dispassionate attitude towards food seeks to enable both nourishment and the pursuit of the extinction of the flame of desire in nirvana. Even though the texts formulate practical prescriptions for monks on how to relate to food to aid them in their pursuit, they also serve as moral standards for lay Sinhalese Buddhists who seek to model their everyday behaviour accordingly.

    This study examines the association between School-Based Health Center (SBHC) presence and school-wide measures of academic achievement and college preparation efforts. Publicly available educational and demographic data from 810 California public high schools were linked to a list of schools with an SBHC. Propensity score matching, a method to reduce bias inherent in non-randomized control studies, was used to select comparison schools. Regression analyses, controlling for proportion of English Language Learners, was conducted for each outcome including: proportion of students participating in three College Board Exams, graduation rates, and meeting University graduation requirements. Findings suggest that SBHC presence is positively associated with college preparation outcomes, but not with academic achievement outcomes (graduation rates or meeting state graduation requirements). Future research must examine underlying mechanisms supporting this association, such as school connectedness. Additional research should explore the role that SBHC staff could have in supporting college preparation efforts. PMID:27009589

    Yeasts are unicellular eukaryotic microorganisms isolated from many foods, and are commonly found in table olive processing where they can play a double role. On one hand, these microorganisms can produce spoilage of fruits due to the production of bad odours and flavours, the accumulation of CO(2) leading to swollen containers, the clouding of brines, the softening of fruits and the degradation of lactic acid, which is especially harmful during table olive storage and packaging. But on the other hand, fortunately, yeasts also possess desirable biochemical activities (lipase, esterase, β-glucosidase, catalase, production of killer factors, etc.) with important technological applications in this fermented vegetable. Recently, the probiotic potential of olive yeasts has begun to be evaluated because many species are able to resist the passage through the gastrointestinal tract and show beneficial effects on the host. In this way, yeasts may improve consumers' health by decreasing cholesterol levels, inhibiting pathogens, degrading non assimilated compounds, producing antioxidants and vitamins, adhering to intestinal cells or by maintaining epithelial barrier integrity. Many yeast species, usually also found in table olive processing, such as Wicherhamomyces anomalus, Saccharomyces cerevisiae, Pichia membranifaciens and Kluyveromyces lactis, have been reported to exhibit some of these properties. Thus, the selection of the most appropriate strains to be used as starters, alone or in combination with lactic acid bacteria, is a promising research line to develop in a near future which might improve the added value of the commercialized product.

    The current experiment examined the development of children's ability to comprehend concurrent conflicting desires (i.e., both wanting and not wanting something at the same time). Participants were 4- to 7-year-old children and a group of undergraduate students (N = 20 in each age group). Results showed that the 6- and 7-year-old children understood concurrent conflicting desires at levels that were well above chance. There was evidence that even some of the 5-year-olds exhibited an emerging comprehension of conflicting desires. However, the 4-year-old children showed little ability to appreciate conflicting desire states. As such, children showed appreciation for conflicting desires at younger ages than suggested by previous research. In addition, significant relationships were observed between children's concurrent conflicting desire understanding and their theory of mind (ToM) and executive functioning (EF) skills, even after controlling for chronological and verbal age.

    We assessed 2 forms of agreement between mothers’ and fathers’ socially desirable responding in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States (N = 1110 families). Mothers and fathers in all nine countries reported socially desirable responding in the upper half of the distribution, and countries varied minimally (but China was higher than the cross-country grand mean and Sweden lower). Mothers and fathers did not differ in reported levels of socially desirable responding, and mothers’ and fathers’ socially desirable responding were largely uncorrelated. With one exception, mothers’ and fathers’ socially desirable responding were similarly correlated with self-perceptions of parenting, and correlations varied somewhat across countries. These findings are set in a discussion of socially desirable responding, cultural psychology, and family systems. PMID:25043708

    Lyon, Ellen Beth

    1998-09-01

    This research project investigated the influence of homogeneous (like-ability) review pairs coupled with heterogeneous (mixed-ability) cooperative learning groups using computer-assisted instruction (CAI) on academic achievement and attitude toward science in eighth grade Earth science students. Subjects were placed into academic quartiles (Hi, Med-Hi, Med-Lo, and Lo) based on achievement. Cooperative learning groups of four (one student from each academic quartile) were formed in all classes, within which students completed CAI through a software package entitled Geoscience Education Through Interactive Technology, or GETITspTM. Each day, when computer activities were completed, students in the experimental classes were divided into homogeneous review pairs to review their work. The students in the control classes were divided into heterogeneous review pairs to review their work. The effects of the experimental treatment were measured by pretest, posttest, and delayed posttest measures, by pre- and post-student attitude scales, and by evaluation of amendments students made to their work during the time spent in review pairs. Results showed that student achievement was not significantly influenced by placement in homogeneous or heterogeneous review pairs, regardless of academic quartile assignment. Student attitude toward science as a school subject did not change significantly due to experimental treatment. Achievement retention of students in experimental and control groups within each quartile showed no significant difference. Notebook amendment patterns showed some significant differences in a few categories. For the Hi quartile, there were significant differences in numbers of deletion amendments and substitution amendments between the experimental and the control group. In both cases, subjects in the experimental group (homogeneous review pairs) made greater number of amendments then those in the control group (heterogeneous review pairs). For the Lo quartile

    2010-01-01

    Although studies have identified a relationship between a history of child sexual abuse (CSA) and problems with hypoactive sexual desire, little is known about the potential cognitive and affective mechanisms involved in the sexual desire of women with a history of CSA. In this study, 27 women with a history of CSA and 22 women with no history of abuse were asked to write about sexual and non sexual topics. The Linguistic Inquiry Word Count software program was used to compute the percentage of words that fell into positive emotions, negative emotions, body, and sex categories. As expected, women with a history of CSA used more negative emotions words when writing about sexual topics, but not non-sexual topics, compared to non-abused women. Women with a history of CSA also used more sex words when writing about the non-sexual topics compared to non-abused women. Frequencies of body and sex words used in the sexual texts were positively linked to levels of sexual desire function. This association was not different between women with and without a history of CSA. A history of CSA remained an independent predictor of levels of sexual desire dysfunction even when taking into consideration the language used in the sexual texts, indicating that there may be aspects of the sexual desire experienced by women with a history of CSA that differ from non-abused women that remain unexplored.

  11. To be or not to be in sexual desire: the androgen dilemma.

    PubMed

    Nappi, R E

    2015-10-01

    The androgen milieu and sexual desire in women seem to be tightly linked because they both decline with age. However, we are still missing a cut-off plasma level for androgens (total testosterone, free testosterone) or androgen precursors (androstenedione, dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS)) to diagnose androgen deficiency in clinical practice. Apart from the complex multidimensional nature of sexual desire across the reproductive lifespan, the correlation between measurements of testosterone and specific signs and symptoms has been difficult because, according to guidelines, most available assays are unreliable at baseline and under hormonal treatments. Recent data obtained with accurate methods based on mass spectrometry to measure total testosterone levels found a significant positive association with sexual desire, arousal and masturbation in midlife US women across the menopausal transition. Even in a European cohort of healthy women aged 19-65 years, sexual desire, measured with a validated questionnaire, correlated overall with free testosterone and androstenedione measured with mass spectrometry. Collectively, these data support the therapeutic use of testosterone for low desire and sexual dysfunction in those clinical conditions in which androgen deficiency may be accurately diagnosed.

    Cultural desire is considered to be a prerequisite for developing cultural competence. This study explored cultural desire among student nurses towards Aboriginal peoples and its association with participation in a one-semester unit on Aboriginal health through a cross-sectional survey. Our main outcome, cultural desire, was measured using two items level of agreement with Aboriginal health being an integral component of the nursing curriculum and an expressed interest in Aboriginal health. 220 (74.58%) student nurses completed the survey. Completing the Aboriginal Health and wellbeing unit did not influence students' opinions on inclusion of the unit as part of the nursing curriculum (odds ratio OR 0.73, 95% CI 0.43-1.29) or their overall cultural desire (mean difference = -0.69, 95% CI -1.29 to -0.08, p = 0.026). Students who completed the unit reported a higher understanding of Aboriginal health (OR = 2.35, 95% CI = 1.35-4.08) but lower interest levels in the subject (OR = 0.45, 95% CI: 0.24-0.84). Further research is necessary to explore how and when cultural desire might develop in nurses who are trained in cultural competence particularly in the contexts of post-colonial disparities and political conflict.

  19. Exploring the effects of sexual desire discrepancy among married couples.

    2014-04-01

    Previous studies have found associations between the individual discrepancy of desired sexual frequency and actual sexual frequency and relational outcomes among premarital couples. The present study extended this research by using a sample of 1,054 married couples to explore how actor and partner individual sexual desire discrepancy (SDD) scores were associated with relationship satisfaction, stability, communication, and conflict during marriage. All participants took an online survey which assessed both couple sexual dynamics and relationship outcomes. Findings suggested that higher actor individual SDD was generally associated with negative relational outcomes, including lower reported relationship satisfaction, stability, and more reported couple conflict. These effects were found after controlling for background factors, baseline sexual frequency and desire, and couple desire discrepancies. Some partner effects were also found and were generally in the same direction. Marital length did not moderate the effects found although gender moderated associations between individual SDD and reported couple communication. Negative associations between individual SDD and communication were particularly strong when the husband reported high discrepancies between desired and actual sexual frequency. Results suggested that higher individual sexual desire discrepancies among married individuals may undermine relationship well-being. Applications of these findings to a clinical setting are also discussed. PMID:24045904

    Hepatitis C virus (HCV), a major cause of liver disease throughout the world, is difficult to treat with interferon (IFN) (and various formulations and combinations thereof) being the only approved molecule available. It has been investigated recently that proinflammatory chemokine interleukin-8 (IL-8) induced by HCV partially inhibits the antiviral IFN-α therapy. Therefore, the current study was aimed to prospectively utilize the baseline IL-8 levels in the HCV infected serum and predicts its role in sustained virological response (SVR) to IFN-α+ribavirin therapy, in chronic HCV patients in Pakistan. One hundred and ten hepatitis C patients without any other infections underwent IFN-α+ribavirin combination treatment. Baseline IL-8 levels were determined before starting of the therapy for all these patients. Fifteen normal volunteers negative for HCV were kept as control. The baseline IL-8 levels were found significantly higher in all HCV positive patients as compared to normal healthy volunteers (1083.54 ± 85.72 pg/ml versus 6.99 ± 1.05 pg/ml [mean ± SEM], p<0.01) and were also significantly higher in non-responders than responders (p<0.05). Comparatively higher mean baseline IL-8 levels were observed in non-responders (2442.02 ± 159.92 pg/ml), than late (1009.31 ± 45.31) and rapid (540.91 ± 27.06 pg/ml) responders. Significant relation was observed between baseline IL-8 level and response to IFN therapy (p<0.01). Results of this study suggest that increased levels of IL-8 in HCV infection might be involved in pathogenesis, persistence and resistance to IFN-α+ribavirin combination therapy. PMID:21554996

    2015-11-15

    The role of adsorption and/or complexation in removal of reactive or unreactive effluent phosphorus by already formed chemical precipitates or complexes has been investigated. Potential operational efficiency gains resulting from age of chemically precipitated tertiary alum sludge and the recycle of sludge to the process stream was undertaken at the Iowa Hill Water Reclamation Facility which employs the DensaDeg(®) process (IDI, Richmond, VA) for tertiary chemical P removal to achieve a filtered final effluent total phosphorus concentration of <30 μg/L. The effect of sludge solids age was found to be insignificant over the solids retention time (SRT) of 2-8 days, indicating that the solids were unaffected by the aging effects of decreasing porosity and surface acidity. The bulk of solids inventory was retained in the clarifier blanket, providing no advantage in P removal from increased solids inventory at higher SRTs. When solids recycle was redirected from the traditional location of the flocculation reactor to a point just prior to chemical addition in the chemical mixing reactor, lower effluent soluble P concentrations at lower molar doses of aluminum were achieved. At laboratory scale, the "spent" or "waste" chemical alum sludge from P removal showed high capacity and rapid kinetics for P sorption from real wastewater effluents. Saturation concentrations were in the range of 8-29 mg soluble reactive P/g solids. Higher saturation concentrations were found at higher temperatures. Alum sludge produced without a coagulant aid polymer had a much higher capacity for P sorption than polymer containing alum sludge. The adsorption reaction reached equilibrium in less than 10 min with 50% or greater removal within the first minute. PMID:26331896

    This report attempts to provide an evolutionary explanation for humans' motivation to strive for money in present-day societies. We propose that people's desire for money is a modern derivate of their desire for food. In three studies, we show the reciprocal association between the incentive value of food and of money. In Study 1, hungry participants were less likely than satiated participants to donate to charity. In Study 2, participants in a room with an olfactory food cue, known to increase the desire to eat, offered less money in a give-some game compared with participants in a room free of scent. In Study 3, participants' desire for money affected the amount of M&M's they ate in a subsequent taste test, but only among participants who were not restricting their food intake in order to manage their weight.

    2013-10-01

    This study used the biological market perspective and influential statistical models from the marketing field to investigate males' and females' expectations regarding which combination of characteristics are most relevant in ensuring desirable partnerships for same-sex individuals. Thus, 358 Brazilian undergraduates assessed eight descriptions of same-gender stimulus targets (formulated with different levels of physical attractiveness, social skills, and current or prospective social status) and evaluated the overall desirability of the targets' expected or probable partners. From the possible combinations, three groups emerged: for one group, mainly composed of men, status characteristics were the most important attributes; for the others, mostly composed of women, social skills or physical characteristics were identified as most important in appealing to a desirable partner. This work expands the understanding of variability in male and female romantic expectations, and its implications are discussed from an evolutionary perspective. PMID:24597452

    A 79-year-old woman suffering from double vision after a 4-year history of MGUS was referred to our hospital. MRI revealed that she had three intracranial plasmacytoma masses and one spinal plasmacytoma mass. Bone marrow aspirates showed 52.4% plasma cell infiltration and immunoelectrophoresis identified serum IgG-M protein, leading to a diagnosis of IgG-type multiple myeloma. IgG was elevated to 3,355 mg/dl and urine type Bence-Jones protein was positive. KL-6, a membrane-bound glycoprotein encoded by Mucin 1 and a marker of interstitial pneumonia, was also elevated to 1,409 mg/dl, but computed tomography of the lungs revealed no obvious pulmonary lesions. Previously reported studies showing that myeloma patients with elevated KL-6 might have a poor prognosis prompted us to treat this patient with a three-drug (bortezomib, cyclophosphamide, and dexamethasone: VCD) combination regimen. When 6 cycles of the regimen had been completed, no M-protein was detectable in her serum. Furthermore, κ free light chain had significantly decreased from 12,700 to 24.8 mg/l. In addition, (18)F-FDG PET/CT revealed reduced mass sizes and no (18)F-FDG uptakes by plasmacytomas. Thus, she was defined as having achieved a stringent complete remission (sCR). We therefore concluded that the VCD combination regimen was highly effective in this multiple myeloma patient with KL-6 elevation. PMID:24850459

    Values reflect how people want to experience the world; emotions reflect how people actually experience the world. Therefore, we propose that across cultures people desire emotions that are consistent with their values. Whereas prior research focused on the desirability of specific affective states or 1 or 2 target emotions, we offer a broader account of desired emotions. After reporting initial evidence for the potential causal effects of values on desired emotions in a preliminary study (N = 200), we tested the predictions of our proposed model in 8 samples (N = 2,328) from distinct world cultural regions. Across cultural samples, we found that people who endorsed values of self-transcendence (e.g., benevolence) wanted to feel more empathy and compassion, people who endorsed values of self-enhancement (e.g., power) wanted to feel more anger and pride, people who endorsed values of openness to change (e.g., self-direction) wanted to feel more interest and excitement, and people who endorsed values of conservation (e.g., tradition) wanted to feel more calmness and less fear. These patterns were independent of differences in emotional experience. We discuss the implications of our value-based account of desired emotions for understanding emotion regulation, culture, and other individual differences. (PsycINFO Database Record PMID:26524003

    The investigation presented here explores the hypothesis that participants are less likely to respond in a socially desirable fashion on self-report questionnaires completed on the Web relative to those completed in the laboratory--the candor hypothesis. A battery of social desirability questionnaires (i.e., Balanced Inventory of Desirable Responding [Paulhaus, 1984], Marlowe-Crowne Social Desirability Scale [Crowne & Marlowe, 1964], Eysenck Personality Questionnaire-Revised Lie Scale [Eysenck & Eysenck, 1994]) was administered to 3 groups: 2 groups consisted of undergraduate participants who were randomly assigned to complete the measures either in the laboratory (n = 60) or on the Web (n = 60), and 1 group consisted of self-selected participants who visited our experimental Web page and completed the measures online (n = 284). This design allowed us to assess the role of Web administration while controlling for differences in sample type, an oft-neglected issue in the Web literature. Results do not support the claim that administering self-report measures over the Web results in a decrease in socially desirable responding. Furthermore, these findings highlight the problems associated with confounding sample and medium. Implications for the use of Web as a research tool are discussed. PMID:17134335

    Studies on the characteristics of individuals with hypersexual disorder have been accumulating due to increasing concerns about problematic hypersexual behavior (PHB). Currently, relatively little is known about the underlying behavioral and neural mechanisms of sexual desire. Our study aimed to investigate the neural correlates of sexual desire with event-related functional magnetic resonance imaging (fMRI). Twenty-three individuals with PHB and 22 age-matched healthy controls were scanned while they passively viewed sexual and nonsexual stimuli. The subjects' levels of sexual desire were assessed in response to each sexual stimulus. Relative to controls, individuals with PHB experienced more frequent and enhanced sexual desire during exposure to sexual stimuli. Greater activation was observed in the caudate nucleus, inferior parietal lobe, dorsal anterior cingulate gyrus, thalamus, and dorsolateral prefrontal cortex in the PHB group than in the control group. In addition, the hemodynamic patterns in the activated areas differed between the groups. Consistent with the findings of brain imaging studies of substance and behavior addiction, individuals with the behavioral characteristics of PHB and enhanced desire exhibited altered activation in the prefrontal cortex and subcortical regions. In conclusion, our results will help to characterize the behaviors and associated neural mechanisms of individuals with PHB. PMID:26648855

    Objectives: To study factors that influence the desire to utilize breast reconstruction after mastectomy, and to investigate the barriers to reconstruction among women in Saudi Arabia. Methods: We conducted a cross-sectional study at 2 surgical centers in Jeddah, Saudi Arabia. A self-administered questionnaire was distributed to all breast cancer patients attending the surgery clinics for follow-up after mastectomy between January and March 2013. Ninety-one patients met the study inclusion criteria. The first part of the questionnaire covered the demographic and socioeconomic information regarding factors that might influence the desire to utilize breast reconstruction including possible barriers. Multivariate logistic regression was used to determine the significant predictors of the desire to undergo reconstruction. Results: Overall, 16.5% of patients underwent breast reconstruction after mastectomy. Young age and high educational attainment were significantly associated with an increased desire to undergo reconstruction. The main barriers to reconstruction were the lack of adequate information on the procedure (63%), concerns on the complications of the procedure (68%), and concerns on the reconstruction interfering with the detection of recurrence (54%). Conclusion: Age and educational level were significant predictors of the desire to utilize breast reconstruction. Furthermore, modifiable barriers included the lack of knowledge and misconceptions on the procedure. Addressing these issues may increase the rate of breast reconstruction in Saudi Arabia.

    Media exposure may have implications for family planning, a public health issue of key importance. Drawing on social comparison theory and social identity theory, a prolonged exposure experiment examined whether media portrayals of women's social roles affect fertility desires among 166 American, nonstudent, never married, childless women ages 21-35 years old. After sign-up and baseline sessions, participants viewed magazine pages five days in a row. Stimuli presented women in either mother/homemaker roles, beauty ideal roles, or professional roles. Three days later, participants again indicated their number of desired children and time planned until first birth. Exposure to mother/homemaker and beauty ideal portrayals increased the number of desired children across time. Exposure to professional portrayals increased the time planned until 1st birth compared to beauty ideal portrayals-this impact was partially mediated by a shift toward more progressive gender norms (per social identity theory) and assimilation (per social comparison theory).

    3,4-Methylenedioxymethamphetamine (MDMA) is an agent of abuse that has been used by over 16 million Americans. Increased energy, elevated mood, bonding with others, and psychedelic effects are desired effects while liver damage, extended depressed mood, sexual assault, rhabdomyolysis, serotonin syndrome, multiorgan failure, cardiovascular events, arrhythmias, and death are possible adverse effects. These desirable and adverse effects of MDMA are extensions of its fascinating pharmacologic and pharmacokinetic profile. In addition to methamphatemine like effects, MDMA also has mescaline like effects and increases the release of cortisol, oxytocin, and antidiuretic hormone. The desirable effects of MDMA are accentuated by the rave or electronic dance music scene where warm temperatures, vigorous dancing, loud music, and light shows accentuate some of the responses. However, the same environment increases the risk of certain harms. Knowledge of the constellation of these factors is needed for education, prevention of harm, and treatment. PMID:24431106

    Sexual experiences, rather than being neutral, are specifically male or female. Yet at present no conceptual framework exists for representing female sexual desire. This has resulted in frequent misrepresentations of female sexual experience. To correct this, a labial framework is proposed, not to replace or oppose a phallic framework, but to exist alongside it. The lips of the mouth and those of the genitals provide a felicitous doubling of sexuality and speech to represent female desire and sexual pleasure as labial. Phallic and labial rhythms are organized differently in sexual arousal and desire, since, as Simone de Beauvoir put it, "Man 'gets stiff,' but woman 'gets wet.'" The labial framework therefore represents female psychosexuality more in terms of "wetware" than of "hardware." PMID:23118235

    The authors examined the role of social desirability in 445 participants' responses to self-reported measures of ageism across two studies. In Study 1, college students and community adults completed the Relating to Older People Evaluation (ROPE) and a short form of the Marlowe-Crowne Social Desirability Scale (M-C SDS). Study 2 was a conceptual replication that included the Fraboni Scale of Ageism (FSA). Correlation analyses confirmed a small but significant relationship between scores on the positive ageist items and the social desirability scale in both studies. Ageist attitudes were correlated with negative ageist behaviors in Study 2. Implications for current views on ageism and strategies for reducing ageist attitudes and behaviors in everyday life are discussed. PMID:24652882

    This research addresses the interrelations existing between trajectories of intimate partnerships and attitudes toward sexuality, sexual desire, and sexual satisfaction. It is based on a dataset of 600 adults aged 25-46 living in Geneva (Switzerland) and uses innovative multivariate techniques for clustering life trajectories. The results emphasize the diversity of men's and women's trajectories of intimate partnerships. Trajectories with frequent and short-term partnerships are associated with recreational attitudes and higher solitary and dyadic sexual desire. In contrast, trajectories featuring few or no intimate partnerships are associated with traditional sexual attitudes and less sexual desire. Women's attitudes toward sexuality are more strongly associated with their intimate trajectories than men's. This suggests that men and women do not develop their sexuality in the same relation with intimacy. The results are referred to the gendered master status hypothesis. PMID:26047692

    The recently discovered iron-based superconductors are potential candidates for high-field magnet applications. However, the critical current densities (Jc) of iron-based superconducting wires remain far below the level needed for practical applications. Here, we show that the transport Jc of Ba1−xKxFe2As2/Ag tapes is significantly enhanced by the combination process of cold flat rolling and uniaxial pressing. At 4.2 K, Jc exceeds the practical level of 105 A/cm2 in magnetic fields up to 6 T. The Jc-H curve shows extremely small magnetic field dependence and maintains a high value of 8.6 × 104 A/cm2 in 10 T. These are the highest values reported so far for iron-based superconducting wires. Hardness measurements and microstructure investigations reveal that the superior Jc in our samples is due to the high core density, more textured grains, and a change in the microcrack structure. These results indicate that iron-based superconductors are very promising for high magnetic field applications. PMID:24513646

    The purpose of this study was to understand differences in patterns of supervisor support desired by female victims of intimate partner violence (IPV) and to examine whether the pattern of support desired at work is reflective of a woman's stage of change in the abusive relationship, IPV-related work interference, and IPV-related job reprimands or job loss. We conducted interviews in Spanish or English with adult women working in low-income jobs who had been physically or sexually abused by an intimate partner/ ex-partner in the past year ( N = 133). Cluster analysis revealed three distinct clusters that form a hierarchy of type of support wanted: those who desired limited support; those who desired confidential, time-off, and emotional support; and those who desired support in wide variety of ways from their supervisor. The clusters appeared to reflect stages of behavior change in an abusive relationship. Specifically, the limited-support cluster may represent an early precontemplation stage, with women reporting the least interference with work. The support-in-every-way cluster may represent later stages of change, in which women are breaking away from the abusive partner and report the greatest interference with work. Women in the confidential-, time-off-, and emotional-support cluster are in a transition stage in which they are considering change and are exploring options in their abusive relationship. Understanding the hierarchy of the type of support desired, and its relationship to stages of change in the abusive relationship and work interference, may provide a strong foundation for developing appropriate and effective workplace interventions to guide supervisors in providing support to women experiencing IPV.

    Several serotonin uptake inhibitors, including the long-acting fluoxetine, have been found to decrease alcohol intake in moderately dependent alcoholics. While the mechanism of their effect is not fully elucidated, a previous study with citalopram indicated that decreased desire to drink may be an important factor. Therefore, we tested fluoxetine effects on alcohol intake and desire to drink in a placebo-controlled study. Subjects, recruited by advertisement, were mildly/moderately dependent alcoholics (12 male, four female, aged 19-59 years, healthy, non-depressed) who did not believe they had a drinking problem and were not requesting treatment. After a 1 week baseline they received, single-blind, 2 weeks placebo followed by 2 weeks fluoxetine 60 mg/day. As out-patients, subjects recorded daily standard drinks (13.6 g ethanol) and rated interest, desire, craving and liking for alcohol biweekly. Each out-patient period was immediately followed by a double-blind experimental drinking session. Out-patient daily drinks slightly decreased during fluoxetine to 6.6 +/- 0.9 (mean +/- S.E.M.) compared with during placebo (7.16 +/- 0.95, p = 0.07, N.S.) and baseline (7.18 +/- 1.0, p > 0.1, N.S.). Desire, interest and craving for alcohol decreased during fluoxetine vs placebo baseline (p < 0.05), but not vs placebo. Appetite loss and decrease in food intake (p < 0.01, fluoxetine vs placebo) correlated with each other (r = 0.91, p < 0.01) but neither correlated with decrease in alcohol intake (appetite: r = 0.26, N.S.; food intake: r = 0.22, N.S.). Weight loss occurred during fluoxetine (p < 0.05 vs placebo) but did not correlate with decrease in alcohol intake (r = 0.1, N.S.). In the experimental drinking sessions after placebo and fluoxetine treatments subjects rated their desire for each of 18 mini-drinks (each one-third of a standard drink) offered at 5 min intervals. Fluoxetine decreased desire to drink throughout the sessions; both mean and maximum desire ratings were

    The authors seeks answers to two key questions: Is an nuclear-weapons-free-world (NWFW) desirable, and is it feasible? Organized into six parts, the book begins with a historical review of attempts to abolish nuclear weapons. Five subsequent parts address the desirability of an NWFW, its feasibility, alternative routes to this goal, and intermediate steps to this end. The authors deals with many obstacles and difficulties facing those who wish to progress from today`s world of 50,000 or more nuclear weapons to one where none exist and strong international verification assures that no rogue state will resurrect these dread devices.

    The flood events present during the last years in different basins of the Colombian territory have raised questions on the sensitivity of the regions and if this regions have common features. From previous studies it seems important features in the sensitivity of the flood process were: land cover change, precipitation anomalies and these related to impacts of agriculture management and water management deficiencies, among others. A significant government investment in the outreach activities for adopting and promoting the Colombia National Action Plan on Climate Change (NAPCC) is being carried out in different sectors and regions, having as a priority the agriculture sector. However, more information is still needed in the local environment in order to assess were the regions have this sensitivity. Also the continuous change in one region with seasonal agricultural practices have been pointed out as a critical information for optimal sustainable development. This combined spatio-temporal dynamics of crops cycle in relation to climate change (or variations) has an important impact on flooding events at basin areas. This research will develop on the assessment and optimization of the aggregated impact of flood events due to determinate the spatio-temporal dynamic of changes in agricultural management practices. A number of common best agricultural practices have been identified to explore their effect in a spatial hydrological model that will evaluate overall changes. The optimization process consists on the evaluation of best performance in the agricultural production, without having to change crops activities or move to other regions. To achieve this objectives a deep analysis of different models combined with current and future climate scenarios have been planned. An algorithm have been formulated to cover the parametric updates such that the optimal temporal identification will be evaluated in different region on the case study area.

    Background: Social desirability may affect different aspects of people’s quality of life. One of the impressive dimensions of quality of life is mental health. The prevalence of Minor Psychiatric Disorders (MPD) among health care workers is higher than other health workers. This article aims at evaluating the relationship between social desirability and MPD among nurses in southern Iran. Method: A cross-sectional study was carried out on 765 nurses who had been employed in hospitals in the southern provinces of Iran. The 12-item General Health Questionnaire (GHQ-12) and Marlowe-Crowne Social Desirability Scale (MC-SDS) were used for evaluating the MPD and social desirability in nurses, respectively. The Robust Regression was used to determine any quantified relationship between social desirability and the level of MPD with adjusted age, gender, work experience, marital status, and level of education. Result: The mean scores of GHQ-12 and MC-SDS were 13.02±5.64 (out of 36) and 20.17±4.76 (out of 33), respectively. The result of Robust Regression indicated that gender and social desirability were statistically significant in affecting MPD. Conclusion: The prevalence of MPD in female nurses was higher than males. Nurses with higher social desirability scores had the tendency to report lower levels of MPD. PMID:26448957

    Background To identify the ranges of hemoglobin A1c (HbA1c), systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDL-C) levels which are associated with the lowest all-cause mortality. Methods A retrospective cohort of 12,643 type 2 diabetic patients (aged ≥18 years) were generated from 2002 to 2010, in Far-Eastern Memorial Hospital, New Taipei city, Taiwan. Patients were identified to include any outpatient diabetes diagnosis (ICD-9: 250), and drug prescriptions that included any oral hypoglycemic agents or insulin prescribed during the 6 months following their first outpatient visit for diabetes. HbA1c, SBP, and LDL-C levels were assessed by the mean value of all available data, from index date to death or censor date. Deaths were ascertained by matching patient records with the Taiwan National Register of Deaths. Results Our results showed general U-shaped associations, where the lowest hazard ratios occurred at HbA1c 7.0–8.0%, SBP 130–140 mmHg, and LDL-C 100–130 mg/dL. The risk of mortality gradually increases if the patient's mean HbA1c, SBP, or LDL-C during the follow-up period was higher or lower than these ranges. In comparison to the whole population, the adjusted hazard ratio (95% CI) for patients with HbA1c 7.0–8.0%, SBP 130–140 mmHg, and LDL-C 100–130 mg/dL were 0.69 (0.62–0.77), 0.80 (0.72–0.90), and 0.68 (0.61–0.75), respectively. Conclusions In our type 2 diabetic cohort, the patients with HbA1c 7.0–8.0%, SBP 130–140 mmHg, or LDL-C 100–130 mg/dL had the lowest all-cause mortality. Additional research is needed to confirm these associations and to further investigate their detailed mechanisms. PMID:25347712

    A paucity of research has examined the utility of curriculum-based measurement (CBM) for data-based decision making at the secondary level. As schools move to multitiered systems of service delivery, it is conceivable that multiple screening measures will be used that address various academic subject areas. The value of including different CBM indices measures is not well understood. The purpose of this study was to (a) examine the relationship among a variety of reading, writing, and mathematics CBM indices administered to 249 seventh-grade students; (b) investigate amount and patterns of growth; and (c) examine predictive validity to a high-stakes state test using latent factor analysis and multiple indicator growth models. Results indicated strong correspondence among CBM types for fall static scores but weak relationships among slopes. Different patterns of growth were yielded for CBM writing than for CBM reading and mathematics. Findings from this study suggested that although reading, mathematics, and writing CBM were independently and moderately related to both English Language Arts and Math test scores, reading was the strongest predictor when all 3 CBM constructs were considered jointly.

    To keep the Earth System in a desirable region of its state space, such as the recently suggested 'tolerable environment and development window', 'planetary boundaries', or 'safe (and just) operating space', in addition to the identification of the quantitative internal dynamics and the available options for influencing it (management), there is an urgent need to understand the systems' state space structure with regard to questions such as (i) which of its parts can be reached from which others with or without leaving the desirable region, (ii) which parts are in a variety of senses 'safe' to stay in when management options break away, and which qualitative decision problems may occur as a consequence of this structure. To complement existing approaches from optimal control focusing on quantitative optimization and being much applied in both engineering and integrated assessment, we develop a mathematical theory of the qualitative topology that partitions the state space of a dynamical system with management options and desirable states including terminology suggestions for the various resulting parts. Our detailed formal classification of the possible states and management options with respect to the possibility of avoiding or leaving the undesired region indicates that before performing some form of quantitative optimization, the sustainable management of the Earth System may require decisions of a more discrete type, e.g. choosing between ultimate safety and permanent desirability, or between permanent safety and increasing future options.

  4. Women selectively guard their (desirable) mates from ovulating women.

    2016-04-01

    For women, forming close, cooperative relationships with other women at once poses important opportunities and possible threats-including to mate retention. To maximize the benefits and minimize the costs of same-sex social relationships, we propose that women's mate guarding is functionally flexible and that women are sensitive to both interpersonal and contextual cues indicating whether other women might be likely and effective mate poachers. Here, we assess one such cue: other women's fertility. Because ovulating (i.e., high-fertility) women are both more attractive to men and also more attracted to (desirable) men, ovulating women may be perceived to pose heightened threats to other women's romantic relationships. Across 4 experiments, partnered women were exposed to photographs of other women taken during either their ovulatory or nonovulatory menstrual-cycle phases, and consistently reported intentions to socially avoid ovulating (but not nonovulating) women-but only when their own partners were highly desirable. Exposure to ovulating women also increased women's sexual desires for their (highly desirable) partners. These findings suggest that women can be sensitive to subtle cues of other women's fertility and respond (e.g., via social exclusion, enhanced sexual attention to own mate) in ways that may facilitate their mate retention goals while not thwarting their affiliative goals.

  8. Ranking, selecting, and prioritising genes with desirability functions

    PubMed Central

    2015-01-01

    In functional genomics experiments, researchers often select genes to follow-up or validate from a long list of differentially expressed genes. Typically, sharp thresholds are used to bin genes into groups such as significant/non-significant or fold change above/below a cut-off value, and ad hoc criteria are also used such as favouring well-known genes. Binning, however, is inefficient and does not take the uncertainty of the measurements into account. Furthermore, p-values, fold-changes, and other outcomes are treated as equally important, and relevant genes may be overlooked with such an approach. Desirability functions are proposed as a way to integrate multiple selection criteria for ranking, selecting, and prioritising genes. These functions map any variable to a continuous 0–1 scale, where one is maximally desirable and zero is unacceptable. Multiple selection criteria are then combined to provide an overall desirability that is used to rank genes. In addition to p-values and fold-changes, further experimental results and information contained in databases can be easily included as criteria. The approach is demonstrated with a breast cancer microarray data set. The functions and an example data set can be found in the desiR package on CRAN (https://cran.r-project.org/web/packages/desiR/) and the development version is available on GitHub (https://github.com/stanlazic/desiR).

    2009-08-01

    Using a sample (N = 453) drawn from a representative sampling frame of couples who are married or living together and have a 3 to 7 year-old child, this study investigates (a) the amount and specific areas of change desired by men and women, (b) the relation between relationship adjustment and desired change; and (c) the ways in which partners negotiate change. On the Areas of Change Questionnaire, women compared with men, wanted greater increases in their partners' emotional and companionate behaviors, instrumental support, and parenting involvement; men wanted greater increases in sex. Using the Actor-Partner Interdependence Model (Kenny, 1996), both men's and women's relationship adjustment predicted desired change (i.e., actor effects), over and above the effects of their partners' adjustment (i.e., partner effects); partner effects were not significant. Each couple was also observed discussing the man's and the woman's top desired change area. Both men and women behaved more positively during the partner-initiated conversations than during their own-initiated conversations. Women, compared with men, were more negative in their own and in their partners' conversations. PMID:19685983

    2010-09-01

    The current method for the immobilization of fission products that accumulate in electrorefiner salt during the electrochemical processing of used metallic nuclear fuel is to encapsulate the electrorefiner salt in a glass-bonded sodalite ceramic waste form. This process was developed by Argonne National Laboratory in the USA and is currently performed at the Idaho National Laboratory for the treatment of Experimental Breeder Reactor-II (EBR-II) used fuel. This process utilizes a “once-through” option for the disposal of spent electrorefiner salt; where, after the treatment of the EBR-II fuel, the electrorefiner salt containing the active fission products will be disposed of in the ceramic waste form (CWF). The CWF produced will have low fission product loading of approximately 2 to 5 weight percent due to the limited fuel inventory currently being processed. However; the design and implementation of advanced electrochemical processing facilities to treat used fuel would process much greater quantities fuel. With an advanced processing facility, it would be necessary to selectively remove fission products from the electrorefiner salt for salt recycle and to concentrate the fission products to reduce the volume of high-level waste from the treatment facility. The Korean Atomic Energy Research Institute and the Idaho National Laboratory have been collaborating on I-NERI research projects for a number of years to investigate both aspects of selective fission product separation from electrorefiner salt, and to develop advanced waste forms for the immobilization of the collected fission products. The first joint KAERI/INL I-NERI project titled: 2006-002-K, Separation of Fission Products from Molten LiCl-KCl Salt Used for Electrorefining of Metal Fuels, was successfully completed in 2009 by concentrating and isolating fission products from actual electrorefiner salt used for the treated used EBR-II fuel. Two separation methods were tested and from these tests were

    2007-01-01

    The Crew Exploration Vehicle (CEV) that will travel to the moon and Mars, and all future Exploration vehicles and habitats will be highly computerized, necessitating an accurate method of interaction with the computers. The design of a cursor control device will have to take into consideration g-forces, vibration, gloved operations, and the specific types of tasks to be performed. The study described here is being undertaken to begin identifying characteristics of cursor control devices that will work well for the unique Exploration mission environments. The objective of the study is not to identify a particular device, but to begin identifying design characteristics that are usable and desirable for space missions. Most cursor control devices have strengths and weaknesses; they are more appropriate for some tasks and less suitable for others. The purpose of this study is to collect some initial usability data on a large number of commercially available and proprietary cursor control devices. A software test battery was developed for this purpose. Once data has been collected using these low-level, basic point/click/drag tasks, higher fidelity, scenario-driven evaluations will be conducted with a reduced set of devices. The standard tasks used for testing cursor control devices are based on a model of human movement known as Fitts law. Fitts law predicts that the time to acquire a target is logarithmically related to the distance over the target size. To gather data for analysis with this law, fundamental, low-level tasks are used such as dragging or pointing at various targets of different sizes from various distances. The first four core tasks for the study were based on the ISO 9241-9:(2000) document from the International Organization for Standardization that contains the requirements for non-keyboard input devices. These include two pointing tasks, one dragging and one tracking task. The fifth task from ISO 9241-9, the circular tracking task was not used

    2014-09-01

    Despite a long tradition of studying the relationship between education and fertility outcomes less is known about how educational differences in fertility intentions are formed and translated into achieved births over the life course. This paper provides new insights using data from a large cohort study and Miller's Traits-Desires-Intentions-Behaviour framework for understanding childbearing. We examine how parental aspirations for education, educational ability in childhood, and educational attainment in young adulthood relate to: males' and females' fertility desires in adolescence; fertility intentions in early adulthood; and educational differences in the achievement of fertility intentions. We conclude that family building preferences expressed in adolescence, especially those for the timing of entry into parenthood are shaped by parental socio-economic background, mediated through educational ability and parental expectations for education. In young adulthood, no clear, consistent educational gradient in intended family size is found. However, there is a negative educational gradient in the likelihood of achieving intended births by age 46, especially for women. The findings indicate the importance of educational differences in employment and partnership behaviour in mediating these relationships. PMID:26047539

  3. Misery loves company: when sadness increases the desire for social connectedness.

    Gray, Heather M; Ishii, Keiko; Ambady, Nalini

    2011-11-01

    In three experiments, the authors investigated the effects of sadness on the desire for social connectedness. They hypothesized that sadness serves an adaptive function by motivating people to reach out to others and preferentially attend to information related to one's current level of social connectedness, but only when it is instigated by social loss. Consistent with this hypothesis, the authors observed that sadness induced by an emotional depiction of social loss enhanced (a) attention to nonverbal cues, an important source of information concerning an individual's current level of social connectedness (Experiment 1), and (b) the desire to engage in social behaviors (Experiment 2). In Experiment 3 the authors found that sadness that results from imagined social loss uniquely produced this pattern of effects. Sadness that resulted from imagined failure had different effects on motivation and no effect on sensitivity to nonverbal cues. These results support and refine functional explanations for the universality of sadness. PMID:21873533

  4. Effect of desired speed variability on highway traffic flow.

    PubMed

    2009-06-01

    Traffic flow is a function of many natural, environmental, and human factors. Not only that weather and road condition can vary, but drivers' decisions and policies also can affect the flow. Here we analyze the effect of distribution of desired speeds. We show that a broader distribution can reduce the flow efficiency and increase congestions. Since different drivers react differently to changes in weather or road conditions, such a change leads to a change in desired speed distribution as well. As a result, nonintuitive changes in traffic flow may occur. Besides providing insight and analyzing the underlying mechanism of a collective phenomenon, this example sheds light on a fundamental aspect of computational modeling. Although "mean-field" models that deal with average values only and ignore variability are simpler and easier to analyze, they can very easily turn into oversimplifications and miss relevant qualitative phenomena.

    Acoustic stress waves can be guided to follow pre-determined paths in solids, using elastic anisotropy. Recently, there has been intense interest to design materials and structures that can shield specific regions within the material by redirecting the incident stress-waves along desired paths. Some of the proposed techniques involve variable mass density and stiffness. We have designed a material with isotropic mass density but highly anisotropic elasticity that can guide incident waves along desired trajectories. Harmonic excitations are imposed, and it is shown that the stress-wave energy would travel around a protected central region. The model is also evaluated using numerical simulations, which confirm that majority of the stress-wave energy is guided around the central cavity and is delivered exactly to the opposing face in a location corresponding to the incident excitation location.

    In this paper, we study the order of moves in a mixed international duopoly for differentiated goods, where firms choose whether to set prices sequentially or simultaneously. We discuss the desirable role of the public firm by comparing welfare among three games. We find that, in the three possible roles, the domestic public firm put a lower price, and then produces more than the foreign private firm.

  7. Topology of sustainable management of dynamical systems with desirable states: from defining planetary boundaries to safe operating spaces in the Earth system

    To keep the Earth system in a desirable region of its state space, such as defined by the recently suggested "tolerable environment and development window", "guardrails", "planetary boundaries", or "safe (and just) operating space for humanity", one needs to understand not only the quantitative internal dynamics of the system and the available options for influencing it (management) but also the structure of the system's state space with regard to certain qualitative differences. Important questions are, which state space regions can be reached from which others with or without leaving the desirable region, which regions are in a variety of senses "safe" to stay in when management options might break away, and which qualitative decision problems may occur as a consequence of this topological structure? In this article, we develop a mathematical theory of the qualitative topology of the state space of a dynamical system with management options and desirable states, as a complement to the existing literature on optimal control which is more focussed on quantitative optimization and is much applied in both the engineering and the integrated assessment literature. We suggest a certain terminology for the various resulting regions of the state space and perform a detailed formal classification of the possible states with respect to the possibility of avoiding or leaving the undesired region. Our results indicate that, before performing some form of quantitative optimization such as of indicators of human well-being for achieving certain sustainable development goals, a sustainable and resilient management of the Earth system may require decisions of a more discrete type that come in the form of several dilemmas, e.g. choosing between eventual safety and uninterrupted desirability, or between uninterrupted safety and larger flexibility. We illustrate the concepts and dilemmas drawing on conceptual models from climate science, ecology, coevolutionary Earth system

  8. Desired machines: cinema and the world in its own image.

    PubMed

    Canales, Jimena

    2011-09-01

    In 1895 when the Lumière brothers unveiled their cinematographic camera, many scientists were elated. Scientists hoped that the machine would fulfill a desire that had driven research for nearly half a century: that of capturing the world in its own image. But their elation was surprisingly short-lived, and many researchers quickly distanced themselves from the new medium. The cinematographic camera was soon split into two machines, one for recording and one for projecting, enabling it to further escape from the laboratory. The philosopher Henri Bergson joined scientists, such as Etienne-Jules Marey, who found problems with the new cinematographic order. Those who had worked to make the dream come true found that their efforts had been subverted. This essay focuses on the desire to build a cinematographic camera, with the purpose of elucidating how dreams and reality mix in the development of science and technology. It is about desired machines and their often unexpected results. The interplay between what "is" (the technical), what "ought" (the ethical), and what "could" be (the fantastical) drives scientific research. PMID:21995220

    2013-04-01

    The desirability function approach is commonly used in industry to tackle multiple response optimization problems. The shortcoming of this approach is that the variability in each predicted response is ignored. It is now evident that the actual response may fall outside the acceptable region even though the predicted response at the optimal solution has a high overall desirability score. An augmented approach to the desirability function (AADF) is put forward to rectify this problem. Nevertheless the AADF is easily affected by outliers since the AADF is constructed based on the Ordinary Least Squares (OLS) estimate which is not resistant to outliers. As an alternative, we propose a robust MM-estimator to estimate the parameters of the Response Surface Model (RSM) and incorporated the estimated parameters in the augmented approach framework. A numerical example is presented to assess the performance of the AADF-MM based method. The numerical results signify that the AADF-MM based is more efficient than the AADF-OLS based method.

    The People of India database of the Anthropological Survey of India documents 631 cultural, ecological, and economic traits of the 4635 communities to which the entire Indian population is assigned. Focusing on 1342 communities of South India, we looked for correlates of low (1 or 2 children) and high (4 or more children) desired family size (DFS) reported as the norm for any given community by key informants. We found 10 cultural and 18 economic traits to be significantly correlated to high DFS and 21 cultural and 9 economic traits to low DFS. The economic traits so identified are compatible with high family size being desired by parents who have little capability of investing in quality of offspring, but whose children contribute economically from an early age. In contrast, communities desiring low family size are part of the modern intensive agriculture/organized industry/services sector and invest heavily in educating their children. A composite index based on 27 economic traits (CEI) has a high predictive value with respect to the DFS for the entire set of 4635 Indian communities. The 31 cultural traits highly correlated to high or low DFS constitute 5 clusters that can be identified as characterizing scheduled tribes, scheduled castes, rural and landless lower castes, urban upper castes, and Moslems. Whereas economic traits have similar influence on DFS within each of these ethnic categories, Moslems demonstrate a significantly higher DFS for lower values of CEI. PMID:11607687

    Using a topical product is part of the overall strategy for skin cancer prevention. The level of protection attainable when using commercial products is indicated by the Sun Protection Factor (SPF) value, in use everywhere. This value reflects the level of protection primarily in the UVB range. However, UVA radiation also has deleterious effects on the skin, and it is essential to prevent it, which is why products must offer a wide spectrum of protection. Tests conducted in vivo, before any marketing, are done by applying the studied product at a rate of 2.0 mg cm(-2), while users, in practice, only use 1.0-1.5 mg cm(-2). We now know that this reduction in the amount of applied product greatly affects the SPF. To complete the state of knowledge in this area, we sought to evaluate the effect of a decrease in the amount of applied sunscreen product by studying sunscreen creams and oils on the level of protection attainable in the UVA range. We have shown that the PF-UVA is divided by a factor of 2.2, on average, when the amount of applied product is reduced by half, with differences depending on the product type under consideration (cream or oil) and depending on the SPF of the preparation.

    Present study aimed to resolve the conflict between cell growth and magnetosome formation of Acidithiobacillus ferrooxidans (A. ferrooxidans) in batch experiments by applying response surface methodology (RSM) integrated a desirability function approach. The effects of several operating parameters on cell growth (OD600) and magnetosome production (Cmag) were evaluated. The maximum overall desirability (D) of 0.923 was achieved at iron concentration of 125.07mM, shake speed of 122.37rpm and nitrogen concentration of 2.40g/L. Correspondingly, the OD600 and Cmag were 0.522 and 1.196, respectively. The confirmation experiment confirmed that the optimum OD600 and Cmag obtained were in good agreement with the predicted values. The inductively coupled plasma atomic emission spectrometer (ICP-AES) and transmission electron microscopy (TEM) analyses revealed that the production of magnetosomes could be improved via optimization. X-ray diffraction (XRD) showed the magnetosomes are magnetite. Results indicated that RSM with a desirability function was a useful technique to get the maximum OD600 and Cmag simultaneously.

  16. A multi-level differential item functioning analysis of trends in international mathematics and science study: Potential sources of gender and minority difference among U.S. eighth graders' science achievement

    NASA Astrophysics Data System (ADS)

    Qian, Xiaoyu

    Science is an area where a large achievement gap has been observed between White and minority, and between male and female students. The science minority gap has continued as indicated by the National Assessment of Educational Progress and the Trends in International Mathematics and Science Studies (TIMSS). TIMSS also shows a gender gap favoring males emerging at the eighth grade. Both gaps continue to be wider in the number of doctoral degrees and full professorships awarded (NSF, 2008). The current study investigated both minority and gender achievement gaps in science utilizing a multi-level differential item functioning (DIF) methodology (Kamata, 2001) within fully Bayesian framework. All dichotomously coded items from TIMSS 2007 science assessment at eighth grade were analyzed. Both gender DIF and minority DIF were studied. Multi-level models were employed to identify DIF items and sources of DIF at both student and teacher levels. The study found that several student variables were potential sources of achievement gaps. It was also found that gender DIF favoring male students was more noticeable in the content areas of physics and earth science than biology and chemistry. In terms of item type, the majority of these gender DIF items were multiple choice than constructed response items. Female students also performed less well on items requiring visual-spatial ability. Minority students performed significantly worse on physics and earth science items as well. A higher percentage of minority DIF items in earth science and biology were constructed response than multiple choice items, indicating that literacy may be the cause of minority DIF. Three-level model results suggested that some teacher variables may be the cause of DIF variations from teacher to teacher. It is essential for both middle school science teachers and science educators to find instructional methods that work more effectively to improve science achievement of both female and minority students

    Feral cats are abundant in many parts of the world and a source of conservation conflict. Our goal was to clarify the beliefs and desires held by stakeholders regarding feral cat abundance and management. We measured people's desired abundance of feral cats in the Hawaiian Islands and identified an order of preference for 7 feral cat management techniques. In 2011 we disseminated a survey to 5407 Hawaii residents. Approximately 46% of preidentified stakeholders and 20% of random residents responded to the survey (1510 surveys returned). Results from the potential for conflict index revealed a high level of consensus (86.9% of respondents) that feral cat abundance should be decreased. The 3 most common explanatory variables for respondents' stated desires were enjoyment from seeing feral cats (84%), intrinsic value of feral cats (12%), and threat to native fauna (73%). The frequency with which respondents saw cats and change in the perceived abundance of cats also affected respondent's desired abundance of cats; 41.3% of respondents stated that they saw feral cats daily and 44.7% stated that the cat population had increased in recent years. Other potential environmental impacts of feral cats had little affect on desired abundance. The majority of respondents (78%) supported removing feral cats from the natural environment permanently. Consensus convergence models with data from 1388 respondents who completed the relevant questions showed live capture and lethal injection was the most preferred technique and trap-neuter-release was the least preferred technique for managing feral cats. However, the acceptability of each technique varied among stakeholders. Our results suggest that the majority of Hawaii's residents would like to see effective management that reduces the abundance of feral or free-roaming cats. PMID:24372971

    OBJECT To the authors’ knowledge, no previous study has examined the impact of meningioma diagnosis on women’s birth desires and intentions. In an exploratory study, the authors surveyed women affected by meningioma to determine their attitudes toward childbearing and the influences, including physician recommendations, on this major life decision and compared their responses to those of women in the general population. METHODS Meningioma survivors from the Meningioma Mommas online support group participated in an online survey that included questions on their birth desires and intentions, whether the risk of disease recurrence influenced their reproductive decisions, and risks communicated to them by their physicians. Using chi-square and rank-sum tests, the authors compared the survey participants’ responses with those of the general population as assessed by the 2006–2010 National Survey of Family Growth. Logistic regression was used to adjust for differences in age, race, ethnicity, education, parity, pregnancy status, and infertility status in these populations. RESULTS Respondents with meningioma were more likely than those in the general population to report wanting a baby (70% vs 54%, respectively), intending to have a baby (27% vs 12%, respectively), and being very sure about this intention (10% vs 2%, respectively). More than half (32 of 61) of the women of childbearing age reported being advised by a physician about potential risk factors for recurrence of the meningioma, and pregnancy was the most commonly cited risk factor (26 of 61). The most common factor influencing birth desires and intentions was risk of the meningioma returning and requiring more treatment, which was reported by nearly two-thirds of the women in their childbearing years. CONCLUSIONS A majority of the meningioma survivors of childbearing age who completed the survey reported a desire for children, although concern about the risk of meningioma recurrence was an important

    Professional medical ethics demands of health care professionals in addition to specific duties and rules of conduct that they embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired implied attitude of physicians. In a sequel of three articles, a set of three of these concepts is presented in an interpretation that is meant to characterise the morally emotional part of this attitude: "empathy", "compassion" and "care". In the first article of the series, "empathy" has been developed as a mainly cognitive and morally neutral capacity of understanding. In this article, the emotional and virtuous core of the desired professional attitude-compassion-is elaborated. Compassion is distinguished from sympathy, empathy and pity. Several problems of compassion as a spontaneous, warm emotion for being a professional virtue are discussed: especially questions of over-demand, of justice and of concerns because of a possible threat to the patient's dignity and autonomy. An interpretation of compassion as processed and learned professional attitude, that founds dignity on the general idea of man as a sentient being and on solidarity, not on his independence and capacities, is developed. It is meant to rule out the possible side effects and to make compassion as a professional attitude and as professional virtue attractive, teachable and acquirable. In order to reach the adequate warmth and closeness for the particular physician-patient-relation, professional compassion has to be combined with the capacity of empathy. If appropriate, the combination of both empathy and compassion as "empathic compassion" can demand a much warmer attitude towards the patient than each of the elements alone, or the simple addition of them can provide. The concept of "care" that will be discussed in a forthcoming article of this sequel is a missing necessary part to describe the active potential of the desired moral
