Rodríguez, Luis M; García-García, Inés; Correa-Rivas, María S; García-Fragoso, Lourdes

2004-03-01

Jarcho-Levin syndrome, also known as spondylothoracic dysplasia and characterized by short trunk dwarfism, "crab-like" rib cage, with ribs and vertebral defects; it is not uncommon in Puerto Ricans. Many patients die in early infancy due to respiratory compromise associated to lung restriction and the reported cases emphasize mostly the skeletal malformations associated to the syndrome. We report the autopsy findings in a newborn with isolated Jarcho-Levin syndrome emphasizing pulmonary pathology. He was a pre-term male who died of respiratory failure at three hours old and, autopsy findings confirmed the clinical diagnosis. Internal examination showed hypoplastic lungs with normal lobation. The histological structure appeared normal and relatively mature; the diaphragm showed eventration and unilateral absence of musculature. This case shows the worst spectum of the Jarcho-Levin syndrome: pulmonary hypoplasia not compatible with extrauterine life. Since thoracic restriction is present during the fetal period, the degree of pulmonary hypoplasia probably defines survival beyond the neonatal period.

Reward Devaluation: Dot-Probe Meta-Analytic Evidence of Avoidance of Positive Information in Depressed Persons

PubMed Central

Winer, E. Samuel; Salem, Taban

2015-01-01

Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. PMID:26619211

Age differences in goals: implications for health promotion.

PubMed

Zhang, Xin; Fung, Helene; Ching, Bob Ho-hong

2009-05-01

Socioemotional selectivity theory postulates that, as people age, they prioritize emotionally meaningful goals. This study investigated whether these age differences in goals are reflected in how younger (aged 18-36, n = 111) and older adults (aged 62-86, n = 104) evaluated, remembered information from and were persuaded by health messages. Participants were randomly assigned to read health pamphlets with identical factual information but emphasizing emotional or non-emotional goals. Findings showed that health messages that emphasized emotional goals, but not those that emphasized future-oriented or neutral goals, were better remembered, were evaluated more positively and led to greater behavioral changes among older adults, but not younger adults. These findings suggest that health messages targeting older adults may be more effective if they are framed in ways that emphasize love and caring.

Polcari, Ingrid; Moon, Amanda; Mathes, Erin F; Gilmore, Elaine S; Paller, Amy S

2014-12-01

Linear morphea en coup de sabre (ECDS) is a form of localized scleroderma that predominantly affects the pediatric population, with a median age of 10 years at presentation. The existence of neurologic findings in association with ECDS has been well described in the literature. Here we describe 4 patients with ECDS who presented with headaches, which were typical migraines in 3 of the patients. The headaches preceded the onset of cutaneous findings by at least 6 months. Our patients' cases emphasize both the importance of recognizing headaches as a harbinger of ECDS and the necessity of performing thorough cutaneous examination in patients with unexplained headaches or other neurologic disease.

Anteby, S O; Schenker, J G; Polishuk, W Z

1975-01-01

Laparoscopy was performed in 223 patients with acute pelvic pain but without a definite diagnosis. The clinically suspected diagnosis was confirmed by laparoscopy in only 57 patients (25%). Laparotomy was thus avoided in 145 patients (65%). The endoscopic findings in the three clinical entities included here are presented: tubal pregnancy, acute appendicitis or torsion of adnexal mass. This study emphasizes the poor correlation between the clinical diagnosis based on history, pelvic examination and physical signs, and the final laparoscopic findings. The value of laparoscopy in evaluation of acute pelvic disease is stressed. PMID:124158

Bridging the Mechanical and the Human Mind: Spontaneous Mimicry of a Physically Present Android

PubMed Central

Hofree, Galit; Ruvolo, Paul; Bartlett, Marian Stewart; Winkielman, Piotr

2014-01-01

The spontaneous mimicry of others' emotional facial expressions constitutes a rudimentary form of empathy and facilitates social understanding. Here, we show that human participants spontaneously match facial expressions of an android physically present in the room with them. This mimicry occurs even though these participants find the android unsettling and are fully aware that it lacks intentionality. Interestingly, a video of that same android elicits weaker mimicry reactions, occurring only in participants who find the android “humanlike.” These findings suggest that spontaneous mimicry depends on the salience of humanlike features highlighted by face-to-face contact, emphasizing the role of presence in human-robot interaction. Further, the findings suggest that mimicry of androids can dissociate from knowledge of artificiality and experienced emotional unease. These findings have implications for theoretical debates about the mechanisms of imitation. They also inform creation of future robots that effectively build rapport and engagement with their human users. PMID:25036365

Did Buddha turn the other cheek too? A comparison of posing biases between Jesus and Buddha.

2015-10-02

People tend to exhibit a leftward bias in posing. Various studies suggest that posing to the left portrays a stronger emotion, whereas posing to the right portrays a more neutral emotion. Religions such as Christianity emphasize the role of strong emotions in religious experience, whereas religions such as Buddhism emphasize the calming of emotions as being important. In the present study, we investigated if the emphasis on emotionality of a religion influences the depiction of their religious figures. Specifically, we coded 484 paintings of Jesus and Buddha from online art databases for whether the deity exhibited a left bias, right bias, or central face presentation. The posing biases were analysed to discover whether paintings of Jesus would more frequently depict a leftward bias than paintings of Buddha. Jesus is more commonly depicted with a leftward bias than Buddha, and Buddha is more commonly depicted with a central face presentation than Jesus. These findings support the idea that the amount of emotionality that is to be conveyed in artwork influences the whether the subject is posed with a leftward bias.

2014-01-01

Neurocutaneous melanosis (NCM) is a rare, congenital non-hereditary syndrome, characterized by multiple pigmented nevi. We report the radiologic findings of a newborn who had extensive cutaneous melanotic nevus with satellite lesions in the brain. Ultrasound showed multiple echogenic foci in the cerebral parenchyma. Subsequent MRI confirmed these lesions as characteristic deposits of melanin. The infant was asymptomatic, but presence of risk factors such as malign transformation or neurological manifestations makes early diagnosis very important. We present this case to emphasize on the radiological findings of this syndrome in order to reach an early diagnosis. PMID:25780540

Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

Furthermore this attractive case proposes a poorly known characteristic of vertebral hemangioma which is usually encountered and described only in skull hemangiomas.

Traits as dimensions or categories? Developmental change in the understanding of trait terms.

Gonzalez, Celia M; Zosuls, Kristina M; Ruble, Diane N

2010-09-01

Recent research has suggested that young children have relatively well-developed trait concepts. However, this literature overlooks potential age-related differences in children's appreciation of the fundamentally dimensional nature of traits. In Study 1, we presented 4-, 5-, and 7-year-old children and adults with sets of characters and asked them to indicate the preferences of a target character who shared appearance attributes with one character (appearance match) and shared a common trait with the other character (trait match). Traits were presented in a way that emphasized either their categorical or their dimensional nature. When the dimensional nature of trait terms was emphasized, the youngest children made fewer trait-based inferences, and the use of traits increased with age. In Study 2, we gave 4-year-old children and adults the same task except that the extent to which appearance cues could serve as a meaningful basis of judgment was varied. Results were consistent with the findings of Study 1, although children were more likely to rely on dimensional presentations of traits in the absence of strong appearance cues.

We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other parameters in the model are also discussed. The role of triplet scalars in constructing a consistent renormalization scheme is emphasized.

Testing Kohn's self-reliance hypothesis among high school adolescents.

PubMed

Davis, R A

1986-01-01

Melvin Kohn and his associates have established that self-reliance promotes a sense of well-being (lower levels of fatalism) among adults. The present study attempts to test this proposition among adolescents. Instead of the usual job-related activities, however, it incorporates an alternative measure of self-reliance--high school curriculum assignment. Consistent with previous findings among adults, the results of this study show that self-reliance among adolescents also promotes a sense of well-being: students enrolled in tracks where close supervision is kept to a minimum and the exercise of initiative is emphasized tended to exhibit lower levels of fatalism. The implications of this finding for adolescents are discussed.

Calyceal diverticula in children: imaging findings and presentations.

PubMed

Ochoa Santiago, Y; Sangüesa Nebot, C; Aliaga, S Picó; Serrano Durbá, A; López, P Ortega

2018-04-26

A calyceal diverticulum consists of a cystic eventration in the renal parenchyma that is lined with transitional cell epithelium with a narrow infundibular connection with the calyces or pelvis of the renal collector system; thus, the term pyelocalyceal diverticulum would be more accurate. Very rare in pediatric patients, calyceal diverticula can be symptomatic and require treatment. Calyceal diverticula are underdiagnosed because they can be mistaken for simple renal cysts on ultrasonography. To determine the approach to their follow-up and management, the diagnosis must be confirmed by excretory-phase computed tomography (CT) or magnetic resonance imaging (MRI). This article aims to show the different ways that calyceal diverticula can present in pediatric patients; it emphasizes the ultrasonographic findings that enable the lesion to be suspected and the definitive findings that confirm the diagnosis on CT and MRI. It also discusses the differential diagnosis with other cystic kidney lesions and their treatment. Copyright © 2018 SERAM. Publicado por Elsevier España, S.L.U. All rights reserved.

Recruitment ad analysis offers new opportunities to attract GPs to short-staffed practices.

As baby-boomer practitioners exit the workforce, physician shortages present new recruitment challenges for practices seeking GPs. This article reports findings from two studies examining GP recruitment practice. GP recruitment ad content analysis (Study 1) demonstrated that both Internet and print ads emphasize job attributes but rarely present family or practice attributes. Contacts at these medical practices reported that their practices offer distinctive family and practice attributes that could be exploited in recruitment advertising (Study 2). Understaffed medical practices seeking to attract GPs may differentiate their job offerings in a crowded market by incorporating family and/or practice attributes into their ads.

Over 130 scientists attended the 8th Conference on Metal Toxicity and Carcinogenesis, presenting their various research concerns and recent findings to stimulate interactions and collaborations among scientists in the field. Several major areas were emphasized, including human & population studies, molecular & cellular mechanisms, biological targets, epigenetic effects, metabolism, and metal mixtures. Here we summarize presentations at the conference sessions and highlight the attendees’ latest work published in this special issue of Biological Trace Element Research. PMID:25975949

Learning and motivation in the human striatum.

PubMed

Shohamy, Daphna

2011-06-01

The past decade has seen a dramatic change in our understanding of the role of the striatum in behavior. Early perspectives emphasized a role for the striatum in habitual learning of stimulus-response associations and sequences of actions. Recent advances from human neuroimaging research suggest a broader role for the striatum in motivated learning. New findings demonstrate that the striatum represents multiple learning signals and highlight the contribution of the striatum across many cognitive domains and contexts. Recent findings also emphasize interactions between the striatum and other specialized brain systems for learning. Together, these findings suggest that the striatum contributes to a distributed network that learns to select actions based on their predicted value in order to optimize behavior.

Understanding the importance of permanent and transitory shocks at business cycle horizons for the UK

NASA Astrophysics Data System (ADS)

Narayan, Paresh Kumar

2008-05-01

The goal of this paper is to examine the relative importance of permanent and transitory shocks in explaining variations in macroeconomic aggregates for the UK at business cycle horizons. Using the common trend-common cycle restrictions, we estimate a variance decomposition of shocks, and find that over short horizons the bulk of the variations in income and consumption were due to permanent shocks while transitory shocks explain the bulk of the variations in investment. Our findings for income and consumption are consistent with real business cycle models which emphasize the role of aggregate supply shocks, while our findings for investment are consistent with the Keynesian school of thought, which emphasizes the role of aggregate demand shocks in explaining business cycles.

Inaugurating Rationalization: Three Field Studies Find Increased Rationalization When Anticipated Realities Become Current.

PubMed

Laurin, Kristin

2018-04-01

People will often rationalize the status quo, reconstruing it in an exaggeratedly positive light. They will even rationalize the status quo they anticipate, emphasizing the upsides and minimizing the downsides of sociopolitical realities they expect to take effect. Drawing on recent findings on the psychological triggers of rationalization, I present results from three field studies, one of which was preregistered, testing the hypothesis that an anticipated reality becoming current triggers an observable boost in people's rationalizations. San Franciscans rationalized a ban on plastic water bottles, Ontarians rationalized a targeted smoking ban, and Americans rationalized the presidency of Donald Trump, more in the days immediately after these realities became current compared with the days immediately before. Additional findings show evidence for a mechanism underlying these behaviors and rule out alternative accounts. These findings carry implications for scholarship on rationalization, for understanding protest behavior, and for policymakers.

The Chinese Experience of Rapid Modernization: Sociocultural Changes, Psychological Consequences?

PubMed Central

Sun, Jiahong; Ryder, Andrew G.

2016-01-01

Mainland China has undergone profound changes dating back to the nineteenth century, including a contemporary period of rapid modernization that began in the 1980s. The result has been dramatic social, cultural, and economic shifts impacting the daily lives of Chinese people. In this paper, we explore the psychological implications of sociocultural transformation in China, emphasizing two central themes. First, rising individualism: findings from social and developmental psychology suggest that China’s rapid development has been accompanied by ever-increasing adherence to individualistic values. Second, rising rates of depression: findings from psychiatric epidemiology point to increasing prevalence of depression over this same time period, particularly in rural settings. We argue that links between sociocultural and psychological shifts in China can be usefully studied through a cultural psychology lens, emphasizing the mutual constitution of culture, mind, and brain. In particular, we note that the link between social change, individualism, and rising mental illness deserves careful attention. Our review suggests that shifting values and socialization practices shape emotion norms of concealment and display, with implications for depressive symptom presentation. The challenge comes with interpretation. Increasing prevalence rates of depression may indeed be a general response to the rapidity of sociocultural change, or a specific consequence of rising individualism—but may also result from increasingly ‘Western’ patterns of symptom presentation, or improvements in diagnostic practice. We conclude by considering the challenges posed to standard universal models of psychological phenomena. PMID:27092093

2016-01-01

A 23-year-old man with a history of alcoholism presented with vomiting, fever, and sharp epigastric pain radiating to the back and flanks. He was diagnosed as a case of acute alcoholic pancreatitis on the basis of clinical findings and investigations. On the next day of presentation, he developed sudden bilateral visual loss. His best-corrected visual acuity was finger counting at one-foot distance in both eyes. He had diffuse whitening in the circumpapillary area, haloes around the retinal vessels (Purtscher flecken) and intra-retinal hemorrhages on ophthalmoscopic examination. Optical coherence tomography revealed bilateral macular edema. These findings were characteristic of Purtscher-like retinopathy. The patient showed systemic and visual improvement at 8 weeks follow-up after receiving the conventional treatment for acute alcoholic pancreatitis. This case emphasizes the importance of fundus examination by an ophthalmologist in the diagnosis of this rare under-diagnosed entity. PMID:27433040

Pseudotumor cerebri (toxic effect of the "magic bullet").

PubMed

Alemayehu, W

1995-10-01

A 10 year-old female patient presented to the outpatient unit of the ophthalmology department of Menelik II Hospital with complaints of inward deviation of the left eye, of three weeks' duration. The patient was on a mega dose of vitamin A 200,000 I.U. (the "magic bullet") daily for two months prior to the onset of the present illness. Physical examination revealed left sixth nerve palsy and bilateral papilloedema in an alert and oriented patient without localizing neurologic findings. The cerebrospinal fluid pressure ( > 250 mm water) was increased and skull X-ray findings were suggestive of increased intracranial pressure (IIP). This case meets the modified Dandy criteria except that a highly likely cause, hypervitaminosis A, is associated. Therefore, a diagnosis of Idiopathic Intracranial Hypertension (IIH) or Pseudotumor Cerebri was made. This disorder and its management is discussed and literature reviewed. The serious and potentially blinding toxic effect of Vitamin A, if consumed in excessive amounts, is emphasized.

Imaging neural signatures of consciousness: 'what', 'when', 'where' and 'how' does it work?

Sergent, C; Naccache, L

2012-01-01

'What' do we call consciousness? 'When' and 'Where' in the brain do conscious states occur, and 'How' conscious processing and conscious access to a given content work? In the present paper, we present a non-exhaustive overview of each of these 4 major issues, we provide the reader with a brief description of the major difficulties related to these issues, we highlight the current theoretical points of debate, and we advocate for the explanatory power of the "global workspace" model of consciousness (Baars 1989; Dehaene and Naccache 2001; Dehaene, Changeux et al. 2006) which can accommodate for a fairly large proportion of current experimental findings, and which can be used to reinterpret apparent contradictory findings within a single theoretical framework. Most notably, we emphasize the crucial importance to distinguish genuine neural signatures of conscious access from neural events correlated with consciousness but occurring either before ('upstream') or after ('downstream').

Designing for adaptation to novelty and change: functional information, emergent feature graphics, and higher-level control.

PubMed

Hajdukiewicz, John R; Vicente, Kim J

2002-01-01

Ecological interface design (EID) is a theoretical framework that aims to support worker adaptation to change and novelty in complex systems. Previous evaluations of EID have emphasized representativeness to enhance generalizability of results to operational settings. The research presented here is complementary, emphasizing experimental control to enhance theory building. Two experiments were conducted to test the impact of functional information and emergent feature graphics on adaptation to novelty and change in a thermal-hydraulic process control microworld. Presenting functional information in an interface using emergent features encouraged experienced participants to become perceptually coupled to the interface and thereby to exhibit higher-level control and more successful adaptation to unanticipated events. The absence of functional information or of emergent features generally led to lower-level control and less success at adaptation, the exception being a minority of participants who compensated by relying on analytical reasoning. These findings may have practical implications for shaping coordination in complex systems and fundamental implications for the development of a general unified theory of coordination for the technical, human, and social sciences. Actual or potential applications of this research include the design of human-computer interfaces that improve safety in complex sociotechnical systems.

This paper presents research findings that advance knowledge around the power and agency families with children with complex care needs (CCN). Our conceptual framework uses concepts from geography towards situating the experiences and social realities of family carers within the 'embodied space of care'. The data originate from a longitudinal qualitative study of Canadian families with children with CCN. Findings reveal that interactions and decision-making processes relating to health and everyday life were complex and socially interconnected, and emphasize the need for provisions for family-based decision-making and enhanced social inclusion of families and the importance of the renegotiation of power.

Perceiving while acting: action affects perception.

PubMed

Schubö, Anna; Prinz, Wolfgang; Aschersleben, Gisa

2004-08-01

In two experiments we studied how motor responses affect stimulus encoding when stimuli and responses are functionally unrelated and merely overlap in time. Such R-S effects across S-R assignments have been reported by Schubö, Aschersleben, and Prinz (2001), who found that stimulus encoding was affected by concurrent response execution in the sense of a contrast (i.e., emphasizing differences). The present study aimed at elucidating the mechanisms underlying this effect. Experiment 1 studied the time course of the R-S effect. Contrast was only obtained for short intertrial intervals (ITIs). With long ITIs contrast turned into assimilation (i.e., emphasizing similarities). Experiment 2 excluded an interpretation of the assimilation effect in terms of motor repetition. Our findings support the notion of a shared representational domain for perception and action control, and suggest that contrast between stimulus and response codes emerges when two S-R assignments compete with each other in perception. When perceptual competition is over, assimilation emerges in memory.

Views of Translational Research from a Somewhat Translational Scientist

PubMed Central

Talman, William T.

2013-01-01

This review arose from a talk entitled “Identifying Targets” and given by the author at EB2011 at the invitation of the American Federation for Medical Research (AFMR). The presentation was part of the AFMR workshop entitled “Keys for Translation: Science and Strategy” and focused on identifying clinically relevant targets as a result of observations made during basic scientific studies. The review emphasizes that targets do not have to be the aim that drives basic discovery, but communication between the basic scientist and clinical investigators may aid recognition of such targets and their translation to clinical applications. Using one line of investigator-initiated research from his own laboratory as an example, the author emphasizes that basic discovery must be hypothesis driven and allowed to follow its logical sequence. Finding treatments, while always an aim of biomedical research, may arise as a result of basic studies that were not originally aimed at a target of translational research. PMID:22781556

The default network and self-generated thought: component processes, dynamic control, and clinical relevance

2014-01-01

Though only a decade has elapsed since the default network was first emphasized as being a large-scale brain system, recent years have brought great insight into the network’s adaptive functions. A growing theme highlights the default network as playing a key role in internally-directed—or self-generated—thought. Here, we synthesize recent findings from cognitive science, neuroscience, and clinical psychology to focus attention on two emerging topics as current and future directions surrounding the default network. First, we present evidence that self-generated thought is a multi-faceted construct whose component processes are supported by different subsystems within the network. Second, we highlight the dynamic nature of the default network, emphasizing its interaction with executive control systems when regulating aspects of internal thought. We conclude by discussing clinical implications of disruptions to the integrity of the network, and consider disorders when thought content becomes polarized or network interactions become disrupted or imbalanced.

Improving reflectance reconstruction from tristimulus values by adaptively combining colorimetric and reflectance similarities

NASA Astrophysics Data System (ADS)

Cao, Bin; Liao, Ningfang; Li, Yasheng; Cheng, Haobo

2017-05-01

The use of spectral reflectance as fundamental color information finds application in diverse fields related to imaging. Many approaches use training sets to train the algorithm used for color classification. In this context, we note that the modification of training sets obviously impacts the accuracy of reflectance reconstruction based on classical reflectance reconstruction methods. Different modifying criteria are not always consistent with each other, since they have different emphases; spectral reflectance similarity focuses on the deviation of reconstructed reflectance, whereas colorimetric similarity emphasizes human perception. We present a method to improve the accuracy of the reconstructed spectral reflectance by adaptively combining colorimetric and spectral reflectance similarities. The different exponential factors of the weighting coefficients were investigated. The spectral reflectance reconstructed by the proposed method exhibits considerable improvements in terms of the root-mean-square error and goodness-of-fit coefficient of the spectral reflectance errors as well as color differences under different illuminants. Our method is applicable to diverse areas such as textiles, printing, art, and other industries.

This commentary builds on the papers presented at the Vanderbilt Conference by emphasizing the importance of better understanding the process of change-making if real change in the real world is to be achieved. The commentary reviews several frameworks and research findings related to achieving large-scale sustainable change that benefits children and families. It calls for the application of systems thinking as a complement to the more micro-level research that was presented at the Vanderbilt conference. Such an approach would have implications for framing of the issue, for the strategies that are taken to try to achieve change, and for research/evaluation methods for studying complex, dynamic, nonlinear systems.

In this article, as two researchers from different traditions in qualitative research (consensual qualitative research and grounded theory), the authors present their shared views on the critical elements of trustworthiness in qualitative data. In addition to making specific recommendations about the integrity of data, the balance between participant meaning and researcher interpretation, and clear communication and application of the findings, they identify ways in which these issues are difficult to negotiate within and across different qualitative approaches. The authors present examples from various qualitative studies, emphasize the need for a shared language to reduce confusion between qualitative traditions and with researchers from a more strictly quantitative orientation, and recommend particular approaches to establishing trustworthiness in qualitative research.

Recent investigations have emphasized the involvement of fronto-subcortical networks to proverb comprehension. Although the prefrontal cortex is thought to be affected by normal aging, relatively little work has been carried out to investigate potential effects of aging on proverb comprehension. In the present investigation participants in three age groups were assessed on a proverb comprehension task and a range of executive function tasks. The older group showed impairment in selecting correct interpretations from alternatives. They also showed executive function deficits, as reflected by reduced working memory and deficient set shifting and inhibition abilities. The findings of the present investigation showed proverb comprehension deficits in normal aging which appeared to be related to reduced executive skills.

Vaccine Message Framing and Parents’ Intent to Immunize Their Infants for MMR

PubMed Central

Finnell, S. Maria E.; Zimet, Gregory D.; Sturm, Lynne A.; Lane, Kathleen A.; Downs, Stephen M.

BACKGROUND AND OBJECTIVE: Emphasizing societal benefits of vaccines has been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children. The objective was to determine whether emphasizing the benefits of measles-mumps-rubella (MMR) vaccination directly to the vaccine recipient or to society differentially impacts parents' vaccine intentions for their infants. METHODS: In a national online survey, parents (N = 802) of infants <12 months old were randomly assigned to receive 1 of 4 MMR vaccine messages: (1) the Centers for Disease Control and Prevention Vaccine Information Statement (VIS), (2) VIS and information emphasizing the MMR vaccine's benefits to the child, (3) VIS and information emphasizing societal benefits, or (4) VIS and information emphasizing benefits both to the child and society. Parents reported their likelihood of vaccinating their infants for MMR on a response scale of 0 (extremely unlikely) to 100 (extremely likely). RESULTS: Compared with the VIS-only group (mean intention = 86.3), parents reported increased vaccine intentions for their infants when receiving additional information emphasizing the MMR vaccine’s benefits either directly to the child (mean intention = 91.6, P = .01) or to both the child and society (mean intention = 90.8, P = .03). Emphasizing the MMR vaccine’s benefits only to society did not increase intentions (mean intention = 86.4, P = .97). CONCLUSIONS: We did not see increases in parents’ MMR vaccine intentions for their infants when societal benefits were emphasized without mention of benefits directly to the child. This finding suggests that providers should emphasize benefits directly to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child. PMID:25136038

Mammary gland tumors (MGTs) are one of the most common neoplasms among dogs in Sri Lanka. However, the clinicopathological diversity of MGTs in Sri Lanka is largely unknown, impeding accurate diagnosis and effective treatment of the disease. The present study investigated the clinicopathological features of MGTs in 74 dogs presented to two veterinary practices in Sri Lanka treated surgically, over a one-year period. Information regarding the patient signalment, clinical presentation, and reproductive history were collected, and each neoplasm was examined histologically. Forty-one (54.4%) dogs were primarily presented for mammary neoplasia, while a MGT was an incidental finding in 33 (44.6%) dogs. The majority of tumors were histologically malignant (n = 65, 87.8%), and 18 malignant tumor sub-types were identified. A significantly higher proportion of malignant tumors were large (>3 cm diameter) and observed in inguinal mammary glands. Nulliparous (n = 42, 55.3%) dogs predominated in the group, and the mean age of MGT diagnosis was 8.0 ± 2.41 years. The present study identified tumor location and size to be predictive of malignancy. A high histological diversity of MGTs was observed. Overall, the present findings emphasize the necessity of improving awareness of MGTs among Sri Lankan clinicians as well as dog owners.

O'Keefe, Daniel J; Jensen, Jakob D

2007-01-01

A meta-analytic review of 93 studies (N = 21,656) finds that in disease prevention messages, gain-framed appeals, which emphasize the advantages of compliance with the communicator's recommendation, are statistically significantly more persuasive than loss-framed appeals, which emphasize the disadvantages of noncompliance. This difference is quite small (corresponding to r = .03), however, and appears attributable to a relatively large (and statistically significant) effect for messages advocating dental hygiene behaviors. Despite very good statistical power, the analysis finds no statistically significant differences in persuasiveness between gain- and loss-framed messages concerning other preventive actions such as safer-sex behaviors, skin cancer prevention behaviors, or diet and nutrition behaviors.

Intraindividual change and variability in daily stress processes: Findings from two measurement-burst diary studies

Sliwinski, Martin J.; Almeida, David M.; Smyth, Joshua; Stawski, Robert S.

2010-01-01

There is little longitudinal information on aging-related changes in emotional responses to negative events. The present manuscript examined intraindividual change and variability in the within-person coupling of daily stress and negative affect (NA) using data from two-measurement burst daily diary studies. Three main findings emerged. First, average reactivity to daily stress increased longitudinally, and this increase was evident across most the adult lifespan. Second, individual differences in emotional reactivity to daily stress exhibited long-term temporal stability, but this stability was greatest in midlife and decreased in old age. And third, reactivity to daily stress varied reliably within-persons (across-time), with individual exhibiting higher levels of reactivity during times when reporting high levels of global subject stress in previous month. Taken together, the present results emphasize the importance of modeling dynamic psychosocial and aging processes that operate across different time scales for understanding age-related changes in daily stress processes.

Hairy-cell leukemia: a rare blood disorder in Asia.

PubMed

Josephine, F P; Nissapatorn, V

2006-01-01

We report a 68-year-old Indian man who was referred to the Hematology Unit for investigation for thrombocytopenia, an incidental finding during a pre-operative screening for prostatectomy. Physical examination was unremarkable. There was no splenomegaly, hepatomegaly or lymphadenopathy. Complete blood counts showed normal hemoglobin and total white cell count with moderate thrombocytopenia. Hairy-cell leukemia was diagnosed based on peripheral blood film, bone-marrow aspirate and trephine biopsy findings, supported by immunophenotyping results by flow cytometry. The purpose of this report is to create awareness of this uncommon presentation and to emphasize that a single-lineage cytopenia or absence of splenomegaly does not exclude the diagnosis of hairy-cell leukemia. Careful attention to morphological detail is important for early diagnosis, especially when low percentages of "hairy" cells are present in the peripheral blood and bone marrow. Early diagnosis is important to ensure that patients obtain maximum benefit from the newer therapeutic agents that have greatly improved the prognosis in this rare disorder.

Failure of Chemotherapy in Hepatocellular Carcinoma Due to Impaired and Dysregulated Primary Liver Drug Metabolizing Enzymes and Drug Transport Proteins: What to Do?

Most of the drugs are metabolized in the liver by the action of drug metabolizing enzymes. In hepatocellular carcinoma (HCC), primary drug metabolizing enzymes are severely dysregulated, leading to failure of chemotherapy. Sorafenib is the only standard systemic drug available, but it still presents certain limitations, and much effort is required to understand who is responsive and who is refractory to the drug. Preventive and therapeutic approaches other than systemic chemotherapy include vaccination, chemoprevention, liver transplantation, surgical resection, and locoregional therapies. This review details the dysregulation of primary drug metabolizing enzymes and drug transport proteins of the liver in HCC and their influence on chemotherapeutic drugs. Furthermore, it emphasizes the adoption of safe alternative therapeutic strategies to chemotherapy. The future of HCC treatment should emphasize the understanding of resistance mechanisms and the finding of novel, safe, and efficacious therapeutic strategies, which will surely benefit patients affected by advanced HCC.

[Effects of perceived benefits about when and how to use a learning strategy].

PubMed

Yamaguchi, Tsuyoshi

2017-04-01

Previous studies have shown a positive correlation between the use of a learning strategy and perceived benefits. However, the impact of perceived benefits as conditional knowledge in metacognitive knowledge has not been examined. The present study investigated the effect of perceived benefits about when (short and long) and how (persistent and suitable) to use learning strategies using two surveys. Each survey utilized a sample of undergraduate students from three different Japanese universities, and the Bayesian hierarchical modeling and within-person variance were used to verify the relationship between the use of a learning strategy and perceived benefits. The students completed questionnaires regarding cognitive (Survey 2a) and metacognitive (Survey 2b) strategies (Survey 1 included two strategies), and achievement goals (without Survey 1). Findings revealed the effects of long-term and short-term persistent perceived benefits on the use of a learning strategy in all the surveys. These results suggest that persistent benefits be emphasized in order to promote the use of learning strategies, and that the appropriate perceived benefits be emphasized in order to become an adaptive learner.

[Dentogene Focus as a Rare Cause of Necrotizing Fasciitis].

2017-02-01

History and clinical findings  We elaborate the case of a 72-year-old patient who presented with a painful swelling of the lower jaw in the emergency unit. Investigations and diagnosis  In the clinical examination and the CT scan, a widespread cervical emphysema was found which raised suspicion for the presence of a necrotizing fasciitis of the head and neck due to aerogenic infection. Close spatial vicinity to the teeth of the left upper and lower jaw was present, so that the necrotizing fasciitis was assumed to be odontogenic. Treatment and course  Based on the clinical presentation and the imaging findings the diagnosis of necrotizing fasciitis in the sense of a possible infection with gas building bacteria accompanying with an infection of the mediastinum was made. Immediately performed therapy included sternotomy and extended surgical debridement of necrosis. Conclusion  The presented case emphasizes that necrotizing fasciitis due to gas-producing infections should be considered as a differential diagnosis for cervical soft tissue emphysema for which an odontogenic focus is the most common cause. Rapid diagnosis is essential for successful treatment consisting of immediate surgical debridement and intravenous antibiotics. © Georg Thieme Verlag KG Stuttgart · New York.

Ren, Shaohua

2013-01-01

A rare case of combined Churg-Strauss syndrome (CSS) and allergic bronchopulmonary aspergillosis (ABPA) was presented. A 41-year-old woman was diagnosed with CSS based upon asthma, eosinophilia (23%), chest radiographic findings, paranasal sinusitis, peripheral neuropathy and positive p- anti-neutrophil cytoplasmic antibodies (pANCA). The diagnosis of ABPA was established on the pathological findings of allegic mucin impaction and fungal hyphae on lung biopsy. It was further proved by positive serum IgE and IgG antibodies specific to afumigatus. The clinical investigation features were reviewed in the patients with combined CSS and ABPA. All patients had the time sequence of the development of CSS after ABPA uniformly, suggesting immunopathogenesis involving the emergence of CSS. The role of lung biopsy in the diagnosis of the condition was emphasized. © 2012 Blackwell Publishing Ltd.

This article presents the findings of a qualitative study of maternal perceptions of parenting following participation in Legacy for Children TM (Legacy), an evidence-based parenting program for low-income mothers of young children and infants. To further examine previous findings and better understand participant experiences, we analyzed semistructured focus-group discussions with predominantly Hispanic and Black, non-Hispanic Legacy mothers at two sites (n = 166) using thematic analysis and grounded theory techniques. The qualitative study presented here investigated how mothers view their parenting following participation in Legacy, allowing participants to describe their experience with the program in their own words, thus capturing an "insider" perspective. Mothers at both sites communicated knowledge and use of positive parenting practices targeted by the goals of Legacy; some site-specific differences emerged related to these parenting practices. These findings align with the interpretation of quantitative results from the randomized controlled trials and further demonstrate the significance of the Legacy program in promoting positive parenting for mothers living in poverty. This study emphasizes the importance of understanding real-world context regarding program efficacy and the benefit of using qualitative research to understand participant experiences. © 2017 Michigan Association for Infant Mental Health.

To find out which attributes, according to Lithuanian dentists, are the most important for a "reliable dentist". All the 140 participants of republican dentists' conference were given a questionnaire. The response rate was 64,3%. The answers about the importance of dentist's attributes were presented on a 5-point Likert scale. The statistical data analysis, using the chi2 criterion was carried out. The importance of behaviour during painful and unpleasant procedures, painless treatment and ability to control stressful situations was emphasized by 87%, 83% and 76% of respondents. To add, qualification, communication skills, ability to answer patient's questions clearly, respecting patient's confidentiality were accentuated as well by 78%, 82%, 84% and 74% of dentists. Although, gender was not an essential quality for 78% of respondents, 62% of them reported that dentist's age was very important. Those, who are over 30, emphasized the value of erudition (chi2=0.464; p<0.01), punctuality (chi2=25.467; p=0.001), specialization (chi2=15.808; p<0.05), low treatment cost (chi2=17.393; p<0.05) more significantly than their younger colleagues. No need to wait for a dentist's appointment was appreciated more by respondents, whose work experience is over 30 years (chi2=20.601; p<0.05). Most Lithuanian dentists emphasized the importance of pain management, painless treatment, behaviour during painful and unpleasant procedures, communication skills and ability to answer patient's questions clearly, which are vital for a "reliable dentist".

In this presentation, I will describe the effects of increased gravity on mammalian development in rodents, from gestation throughout weaning. The work is based on studies of centrifugation-induced hypergravity-rearing, the fundamentals of which will be described. The key variables include: 1) comparison of first-time (primparous) and experienced (multiparous) rodent mothers; 2) prenatal adaptation to the centrifuge; and 3) application of a modest g-load (1.5-g). The reported findings emphasize pregnancy, labor and birth, maternal care and lactation in the dams, and suckling, growth, development, and weaning in the offspring. Pregnancy success and offspring growth and survival will be discussed.

Motivation and justification: a dual-process model of culture in action.

PubMed

Vaisey, Stephen

2009-05-01

This article presents a new model of culture in action. Although most sociologists who study culture emphasize its role in post hoc sense making, sociologists of religion and social psychologists tend to focus on the role beliefs play in motivation. The dual-process model integrates justificatory and motivational approaches by distinguishing between "discursive" and "practical" modes of culture and cognition. The author uses panel data from the National Study of Youth and Religion to illustrate the model's usefulness. Consistent with its predictions, he finds that though respondents cannot articulate clear principles of moral judgment, their choice from a list of moral-cultural scripts strongly predicts later behavior.

The importance of localizing pulmonary veins in atrial septal defect closure!

2011-01-01

An 8-year-old girl was admitted for a simple closure of echocardiographically diagnosed Atrial Septal Defect (ASD). During the operation the right pulmonary veins orifices were not detected in the left atrium and attempt to localize them led to the discovery of three additional anomalies, namely Interrupted Inferior Vena Cava (IIVC), Scimitar syndrome, and systemic arterial supply of the lung. Postoperatively these finding were confirmed by CT angiography. This case report emphasizes the need for adequate preoperative diagnosis and presents a very rare constellation of four congenital anomalies that to the best of our knowledge is not reported before.

Perioperative derangements of fluid and electrolyte homeostasis are rare complications in healthy children. Nonetheless, early diagnosis and treatment are mandatory to avoid a potentially life-threatening situation. However, the variety of underlying pathologies may prove to make accurate diagnosis challenging. This case report presents the management of an unexpected occurrence of a perioperative partial diabetes insipidus with massive fluid loss. Diagnostic and therapeutic procedures are discussed in the context of laboratory findings, and an overview of the existing literature is given. Finally, we emphasize that a multidisciplinary approach is most appropriate for diagnosis, accurate treatment, and follow-up of the patient.

2016-06-01

The fractional uncertainty relation is a mathematical formulation of Heisenberg's uncertainty principle in the framework of fractional quantum mechanics. Two mistaken statements presented in the Comment have been revealed. The origin of each mistaken statement has been clarified and corrected statements have been made. A map between standard quantum mechanics and fractional quantum mechanics has been presented to emphasize the features of fractional quantum mechanics and to avoid misinterpretations of the fractional uncertainty relation. It has been shown that the fractional probability current equation is correct in the area of its applicability. Further studies have to be done to find meaningful quantum physics problems with involvement of the fractional probability current density vector and the extra term emerging in the framework of fractional quantum mechanics.

Rhodotorula is emerging as an important cause of nosocomial and opportunistic infections. We present two cases of Rhodotorula mucilaginosa fungemia diagnosed over a period of 3 months at our hospital. The first case was of a pre-term neonate in the neonatal ICU who presented with respiratory failure and sepsis. The second involved an adult female who had been injured in a road traffic accident requiring an operation for a hematoma and was later shifted to the medical ICU. For a new hospital like ours, finding two cases of Rhodotorula fungemia within a span of 3 months prompted us to describe them in this report. These cases emphasize the emerging importance of Rhodotorula mucilaginosa as a pathogen and the importance of identification and MIC testing for all fungal isolates recovered from the blood stream.

Access to Bridge Employment: Who Finds and Who Does Not Find Work After Retirement?

Dingemans, Ellen; Henkens, Kène; Solinge, Hanna van

2016-08-01

Empirical studies on the determinants of bridge employment have often neglected the fact that some retirees may be unsuccessful in finding a bridge job. We present an integrative framework that emphasizes socioeconomic factors, health status, social context, and psychological factors to explain why some people fully retired after career exit, some participated in bridge jobs, while others unsuccessfully searched for one. Using Dutch panel data for 1,221 retirees, we estimated a multinomial logit model to explain participation in, and unsuccessful searches for, bridge employment. About 1 in 4 retirees participated in bridge employment after retirement, while 7% searched unsuccessfully for such work. Particularly those who experienced involuntary career exit were found to have a higher probability of being unsuccessful at finding bridge employment. The current study provides evidence for the impact of the social context on postretirement work and suggests a cumulative disadvantage in the work domain in later life. © The Author 2015.

Post-operative cognitive dysfunction after knee arthroplasty: a diagnostic dilemma

PubMed Central

Yap, Kiryu K.; Joyner, Peter

2014-01-01

Post-operative cognitive dysfunction (POCD) is common in the elderly, and significantly impacts their recovery. We present an unusual diagnostic challenge where a 65-year-old male presented 4-week post-total knee arthroplasty with acute cognitive dysfunction lasting 19 days. Curiously, there were no findings uncovering a specific cause, but during investigation underlying predisposing factors such as depression, mild memory deficits and generalized brain volume loss were identified. The impression after psychogeriatric review was that of an organic brain syndrome with overlay of depression, with a complex presentation as POCD. After escalation of behavioural disturbance, he was commenced on anti-psychotic/depressant, with immediate response. We emphasize the importance of pre-operative evaluation of cognitive function and risk factors in all geriatric patients undergoing elective surgery, and the need for further characterization of POCD, as well as experimental research elucidating the underlying mechanisms to better identify and treat this important post-surgical phenomenon.

Comparison of meaning and graphophonemic feedback strategies for guided reading instruction of children with language delays.

PubMed

Kouri, Theresa A; Selle, Carrie A; Riley, Sarah A

2006-08-01

Guided reading is a common practice recommended for children in the early stages of literacy development. While experts agree that oral reading facilitates literacy skills, controversy exists concerning which corrective feedback strategies are most effective. The purpose of this study was to compare feedback procedures stemming from 2 different theoretical perspectives on literacy development. Fourteen children with specific language impairment (SLI) and 21 with typically developing language read aloud 2 stories to an adult examiner who presented corrective feedback prompts when reading miscues (errors) occurred. One type of feedback based on whole language principles emphasized meaning aspects of a text. The other type consisted of graphophonemic (GP) word-decoding strategies. Before reading, participants were provided instruction on 5 key words taken from each story text. This instruction emphasized either meaning or GP aspects of specific key words. Story comprehension questions followed readings. Findings indicated that more miscued words were corrected overall through the use of GP feedback cues; however, some meaning-based instructional advantages were indicated for key word identifications for children with SLI. Higher story comprehension scores were yielded in the GP condition for both groups. Both meaning-based and phonemic key word reviews, prior to oral reading, appear to be effective strategies for children with SLI. The use of GP word-decoding cues may be more effective than meaning-based cues for facilitating correction of reading miscues during children's oral readings. Further research findings are discussed along with clinical implications for using corrective feedback procedures.

Discrete mathematics in deaf education: a survey of teachers' knowledge and use.

PubMed

Pagliaro, Claudia M; Kritzer, Karen L

The study documents what deaf education teachers know about discrete mathematics topics and determines if these topics are present in the mathematics curriculum. Survey data were collected from 290 mathematics teachers at center and public school programs serving a minimum of 120 students with hearing loss, grades K-8 or K-12, in the United States. Findings indicate that deaf education teachers are familiar with many discrete mathematics topics but do not include them in instruction because they consider the concepts too complicated for their students. Also, regardless of familiarity level, deaf education teachers are not familiar with discrete mathematics terminology; nor is their mathematics teaching structured to provide opportunities to apply the real-world-oriented activities used in discrete mathematics instruction. Findings emphasize the need for higher expectations of students with hearing loss, and for reform in mathematics curriculum and instruction within deaf education.

Submaximal delayed-onset muscle soreness: correlations between MR imaging findings and clinical measures

1998-01-01

PURPOSE: To assess correlations between muscle edema on magnetic resonance (MR) images and clinical indexes of muscle injury in delayed-onset muscle soreness (DOMS) produced by submaximal exercise protocols. MATERIALS AND METHODS: Sixteen subjects performed 36 elbow flexions ("biceps curls") at one of two submaximal workloads that emphasized eccentric contractions. Changes in MR imaging findings, plasma levels of creatine kinase, and pain scores were correlated. RESULTS: Both exercise protocols produced DOMS in all subjects. The best correlation was between change in creatine kinase level and volume of muscle edema on MR images, regardless of the workload. Correlations tended to be better with the easier exercise protocol. CONCLUSION: Whereas many previous studies of DOMS focused on intense exercise protocols to ensure positive results, the present investigation showed that submaximal workloads are adequate to produce DOMS and that correlations between conventionally measured indexes of injury may be enhanced at lighter exercise intensities.

Mulhearn, Tyler J; Watts, Logan L; Torrence, Brett S; Todd, E Michelle; Turner, Megan R; Connelly, Shane; Mumford, Michael D

2017-01-01

Research misconduct negatively impacts the scientific community and society in general. Providing training in the responsible conduct of research (RCR) to researchers is one viable approach to minimizing research misconduct. Although recent evidence suggests ethics training can indeed be effective, little empirical work has examined the similarities and differences across fields. In the present study, we analyzed 62 empirical studies in engineering, biomedical science, social science, and mixed fields. The findings suggest certain instructional principles, or "golden rules," apply generally to all fields. These golden rules include maintaining a field-specific or field-general approach and emphasizing processes in training. The findings also suggest that content areas contributing to instructional effectiveness vary as a function of field. Generally, it appears that all fields may benefit from taking a multi-pronged approach to ethics education wherein the salient field issues are covered. Implications for RCR education are discussed.

Parent socialization effects in different cultures: significance of directive parenting.

PubMed

Sorkhabi, Nadia

2012-06-01

In this article, the controversy of divergent findings in research on parental socialization effects in different cultures is addressed. Three explanations intended to address divergent findings of socialization effects in different cultures, as advanced by researchers who emphasize cultural differences, are discussed. These include cultural differences in socialization values and goals of parents, parental emotional and cognitive characteristics associated with parenting styles, and adolescents' interpretations or evaluations of their parents' parenting styles. The empirical evidence for and against each of these arguments is examined and an alternative paradigm for understanding and empirical study of developmental outcomes associated with parenting styles in different cultures is suggested. Baumrind's directive parenting style is presented as an alternative to the authoritarian parenting style in understanding the positive developmental effects associated with "strict" parenting in cultures said to have a collectivist orientation. Directions for research on the three explanations are mentioned.

Gender-Atypical Mental Illness as Male Gender Threat.

PubMed

Michniewicz, Kenneth S; Bosson, Jennifer K; Lenes, Joshua G; Chen, Jason I

2016-07-01

The present study examined whether men view gender-atypical (i.e., feminine) psychological disorders as threats to their gender status. Men and women (N = 355) rated their expectations of gender status loss, feelings of distress, and help-seeking intentions in response to 10 different stereotypically masculine and feminine psychological disorders. Men as compared to women expected greater gender status loss for, and reported more distress to, gender-atypical versus gender-typical disorders. Expectations of gender status loss partially mediated the link between participant gender and distress at the thought of gender-atypical disorders. These findings suggest that feminine disorders pose more powerful gender status threats for men than masculine disorders do and that men's expectations of gender status loss for feminine disorders drive their negative reactions to these mental illnesses. The discussion emphasizes the importance of considering the gender-typicality of disorders, and the implications of these findings for clinical interventions. © The Author(s) 2015.

Although only few cases of human fascioliasis have been reported from India previously, both these cases were encountered within a span of three months at this tertiary care centre. Case 1 had significant symptoms with episodes of fever, abdominal pain and eosiniphilia and underwent multiple diagnostic procedures before the correct diagnosis was reached. Case 2, who had few symptoms, had fascioliasis diagnosed with minimal evaluation. These different presentations seen at two ends of the clinical spectrum of disease along with findings of peripheral eosinophilia, and radiological findings led to a presumptive diagnosis that was then confirmed by microscopic examination of bile. Morphometric analysis of ova from these cases was suggestive of infestation with F. gigantica or a F. gigantica-like hybrid. Both patients were treated with triclabendazole which was imported from Geneva. The need to be aware of the possibility of occurrence of this disease and the inclusion of drugs used for treating the disease, in the Indian drug list, should be emphasized.

The effects of concurrent working memory load in attentional processes have been 1 of the most puzzling issues in cognitive psychology. Studies have shown detrimental effects, no effects, and even beneficial effects of working memory load in different attentional tasks. In the present study we attempted to replicate Kim, Kim, and Chun's (2005, Experiment 3b) findings of beneficial effects of concurrent working memory load in a spatial Stroop-like task. In 3 experiments in which our sample was 3 times larger than that in the original Kim et al. study, we could not replicate their findings. The results are discussed in terms of what may have produced the conflicting results, trying to shed light on how working memory load affects attentional tasks. Also, we emphasize the importance of using adequately large samples in cognitive research. Although we acknowledge the relevance of meta-analyses to analyze conflicting results, in the present article we stress (perhaps more important) the power of an essential trademark in science for research development: replicability.

A flexible, multi-faceted, multi-media approach to teaching climate change to non-STEM majors

NASA Astrophysics Data System (ADS)

De Roo, R. D.; Liemohn, M. W.

2011-12-01

The University of Michigan offers a 100-level course entitled, "Our Changing Atmosphere," often taken to fulfill the natural science distribution credit requirement by up to 200 students in non-technical majors per term. This course covers the properties and structure of the atmosphere and how they are changing, emphasizing the global climate and climate change. After a brief introduction to atmospheric basics, highlights from Earth's climate history are presented, followed by modern-day changes to climate, such as air pollution, stratospheric ozone depletion, and global warming. The current format of the course relies heavily on Lecturebook, Lecturetools, and C-tools as online electronic resources for the class. The textbook for the course is managed through Lecturebook, which also provides hyperlinked text and hundreds of built-in questions for homework sets and student review. The recitation lessons are uploaded to Lecturebook, which allows for interactive question-and-answer sessions during class in multiple formats. The University of Michigan's C-tools environment is also used for email distribution and archiving, additional resource postings, and as a backup to these other two websites. The structure of the class permits different instructors to emphasize different facets of climate, and to employ different instructional techniques. For example, the textbook differs depending on the term the course is offered. One of us emphasizes good-vs-bad science usage via video, sound clip, or PDF posting on a weather or climate related topic in every lecture. Good-v-bad science usage of climate topics in research, media reporting, and casual conversation are all discussed by the students and included in the examinations. The other instructor emphasizes the findings of the IPCC, employs hands-on activities in lecture and eschews exams in favor of collaborative homework assignments. The assignments include qualitative and quantitative analyses of climate topics and the exploration of model predictions under differing assumptions.

Impulsivity is a central component of attention-deficit/hyperactivity disorder (ADHD). Delay discounting, or a preference for smaller, immediate rewards over larger, delayed rewards is considered an important aspect of impulsivity, and delay-related impulsivity has been emphasized in etiological models of ADHD. The current study examined whether stimulant medication, an effective treatment for ADHD, reduces discounting of delayed experiential and hypothetical rewards among 49 children (age 9–12 years) with ADHD. Following a practice day, participants completed a 3-day double-blind placebo-controlled acute medication assessment. Active doses were long-acting methylphenidate (Concerta), with the nearest equivalents of 0.3 and 0.6 mg/kg TID immediate-release methylphenidate. On each testing day, participants completed experiential (real-world money in real time) and hypothetical discounting tasks. Relative to placebo, methylphenidate reduced discounting of delayed experiential rewards, but not hypothetical rewards. Broadly consistent with etiological models that emphasize delay-related impulsivity among children with ADHD, these findings provide initial evidence that stimulant medication reduces delay discounting among those with the disorder. The present results also draw attention to task parameters that may influence the sensitivity of various delay discounting measures to medication effects. PMID:19803628

Implicit Self-Importance in an Interpersonal Pronoun Categorization Task.

2014-06-01

Object relations theories emphasize the manner in which the salience/importance of implicit representations of self and other guide interpersonal functioning. Two studies and a pilot test (total N = 304) sought to model such representations. In dyadic contexts, the self is a "you" and the other is a "me", as verified in a pilot test. Study 1 then used a simple categorization task and found evidence for implicit self-importance: The pronoun "you" was categorized more quickly and accurately when presented in a larger font size, whereas the pronoun "me" was categorized more quickly and accurately when presented in a smaller font size. Study 2 showed that this pattern possesses value in understanding individual differences in interpersonal functioning. As predicted, arrogant people scored higher in implicit self-importance in the paradigm. Findings are discussed from the perspective of dyadic interpersonal dynamics.

Repond, J.

2014-09-01

The DHCAL — the Digital Hadron Calorimeter — is a prototype calorimeter based on Resistive Plate Chambers (RPCs). The design emphasizes the imaging capabilities of the detector in an effort to optimize the calorimeter for the application of Particle Flow Algorithms (PFAs) to the reconstruction of hadronic jet energies in a colliding beam environment. The readout of the chambers is segmented into 1 × 1 cm2 pads, each read out with a 1-bit (single threshold) resolution. The prototype with approximately 500,000 readout channels underwent extensive testing in both the Fermilab and CERN test beams. This talk presents preliminary findings from the analysis of data collected at the test beams.

Transformational leadership: What every nursing dean should know.

PubMed

Giddens, Jean

Transformational leadership (TFL) has become a predominant leadership style practiced by leaders across many industries and disciplines, including nursing. As a component of the Full Range Leadership Model proposed by Bass (1985), TFL is characterized by the ability to stimulate, inspire, and motivate followers. Transformational leaders focus on building relationships with people and creating change by emphasizing values. Most TFL literature in nursing focuses on clinical practice with very little representation from academic nursing leadership. This article describes TFL, presents general findings from the literature, discusses this leadership style in the context of academic nursing leadership, makes recommendations for professional development of this leadership approach and offers suggests for future inquiry.

Presented in this article are findings from a descriptive study of a national stratified random sample of 259 women administrators in social work, nursing, and education. Subjects responded to a 54 item, mailed questionnaire about their career experiences. The author explores career support from parents and persons within their work organizations. Barriers of sex discrimination and difficulties balancing career and family responsibilities are included. Finally, the extent to which the women administrators provided career assistance to other women is discussed. Comparisons between the three fields and between top and middle management levels are emphasized. Recommendations are made for increasing women's opportunities for career achievement within the fields studied.

Mediastinal emphysema in mountain climbers: report of two cases and review.

PubMed

Vosk, A; Houston, C S

1977-01-01

Two cases of mediastinal emphysema occurring in healthy individuals climbing to the summit of Mount Rainier (4,393 m.) are described. In both, the condition was probably attributable to a voluntary, forced pressure breathing technique--a modified Valsalva maneuver. The various circumstances in which mediastinal emphysema may occur are discussed, along with its possible serious complication of cardiorespiratory compromise. The means of diagnosis are presented, emphasizing that cases in which the important finding of subcutaneous emphysema is absent may be those in which the danger is greatest. Therapeutic measures that occasionally may be necessary are outlined, though the condition is usually a benign one that subsides without specific treatment.

Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever in a 19-year-old patient who presented maculopapular exanthema in the palmar region and upper limbs, lymphadenopathy, fever, chills, headache, conjunctival hyperemia, nausea, vomiting, dyspnea, myalgia, developing neurological signs and abdominal pain. He was treated with doxycycline with clinical improvement. We emphasize the importance of the recognition of this disease by dermatologists as cutaneous manifestations are the key findings to establish early diagnosis and prevent complications.

There are numerous causes for intracranial calcification in children. We describe an unusual cause of intracranial calcification in a child, namely, nephrogenic diabetes insipidus (NDI). A 12-year-old boy presented with seizures and developmental delay. MRI of the brain revealed intracranial calcification. Evaluation showed findings suggestive of NDI. The lack of evidence of any other metabolic defect suggests that these calcifications were secondary to NDI. He also had anemia for which he was investigated and diagnosed as thalassemia minor. Detailed literature review failed to reveal any reported association between NDI and thalassemia minor. We report this case to emphasize the importance of early diagnosis and treatment of NDI to prevent organic brain damage.

2018-02-01

Rainfall-induced landslides pose a substantial risk to people and infrastructure. For this reason, there have been numerous studies to understand the landslide mechanism. Most of them were performed on the numerical analysis and laboratory experiment. This paper presents a review of existing research on field hydrological condition of soil slopes leading to the initiation of rainfall-induced landslide. Existing methods to study field hydrological response of slopes are first reviewed, emphasizing their limitations and suitability of application. The typical hydrological response profiles in the slope are then discussed. Subsequently, some significant findings on hydrological condition leading to rainfall-induced landslides are summarized and discussed. Finally, several research topics are recommended for future study.

Tc-99m TRODAT is cocaine analog and binds to the dopamine transporter in vivo . Tc-99m TRODAT single-photon emission computed tomography/computed tomography. (SPECT/CT) is useful for demonstrating presynaptic dopaminergic dysfunction in patients with Parkinsonism. However, few reports have shown extrastriatal uptake of Tc-99m TRODAT. We present the case of a 67-year-old male who underwent Tc-99m TRODAT SPECT/CT for evaluation of Parkinsonism. In addition to tracer binding in the striatum, tracer uptake was noted in an osteoid tumor of the clivus. Integrated SPECT/CT enabled precise localization and characterization of the extrastriatal site of tracer binding and emphasizes the importance of such coincidental findings.

Ramsay Hunt syndrome (RHS) is a disorder characterized by herpetic eruptions on the auricle, facial paralysis, and vestibulocochlear dysfunction and is attributed to varicella zoster virus (VZV) infection in the geniculate ganglion. Although it is a common cause of acute peripheral facial paralysis, children are not usually affected. The diagnosis is based on history and physical findings. Treatment of RHS uses a combination of high-dose corticosteroids and acyclovir. This paper presents three cases diagnosed as RHS in the pediatric age group in association with the literature review. The aim of this paper is to emphasize the importance of careful examination and early initiation of therapy in suspected cases of RHS. PMID:26435868

Thermal Analysis of the Vulnerability of the Spacesuit Battery Design to Short-Circuit Conditions (Presentation)

2010-04-22

NREL researchers created a mathematical model of a full 16p-5s spacesuit battery for NASA that captures electrical/thermal behavior during shorts to assess the vulnerability of the battery to pack-internal (cell-external) shorts. They found that relocating the short from battery pack-external (experimental validation) to pack-internal (modeling study) causes substantial additional heating of cells, which can lead to cell thermal runaway. All three layers of the bank-to-bank separator must fail for the pack-internal short scenario to occur. This finding emphasizes the imperative of battery pack assembly cleanliness. The design is tolerant to pack-internal shorts when stored at 0% state of charge.

The orbitofrontal oracle: cortical mechanisms for the prediction and evaluation of specific behavioral outcomes.

PubMed

Rudebeck, Peter H; Murray, Elisabeth A

2014-12-17

The orbitofrontal cortex (OFC) has long been associated with the flexible control of behavior and concepts such as behavioral inhibition, self-control, and emotional regulation. These ideas emphasize the suppression of behaviors and emotions, but OFC's affirmative functions have remained enigmatic. Here we review recent work that has advanced our understanding of this prefrontal area and how its functions are shaped through interaction with subcortical structures such as the amygdala. Recent findings have overturned theories emphasizing behavioral inhibition as OFC's fundamental function. Instead, new findings indicate that OFC provides predictions about specific outcomes associated with stimuli, choices, and actions, especially their moment-to-moment value based on current internal states. OFC function thereby encompasses a broad representation or model of an individual's sensory milieu and potential actions, along with their relationship to likely behavioral outcomes.

In 2016, we undertook a nationally representative wind power perceptions survey of individuals living within 8 km of over 600 projects in the United States, generating 1705 telephone, web, and mail responses. We sought information on a variety of topics, including procedural fairness and its relationship to project attitude, the foci of the present analysis. Here, we present a series of descriptive statistics and regression results, emphasizing those residents who were aware of their local project prior to construction. Sample weighting is employed to account for stratification and non-response. We find that a developer being open and transparent, a communitymore » being able to influence the outcome, and having a say in the planning process are all statistically significant predictors of a process perceived as being ‘fair,’ with an open and transparent developer having the largest effect. We also find developer transparency and ability to influence outcomes to have statistically significant relationships to a more positive attitude, with those findings holding when aesthetics, landscape, and wind turbine sound considerations are controlled for. The results indicate that jurisdictions might consider developing procedures, which ensure citizens are consulted and heard, and benchmarks or best practices for developer interaction with communities and citizens.« less

Empirical research suggests that emotional response during sexual activity discriminates between sexually functional and dysfunctional heterosexual men and women, with clinics presenting lower positive and higher negative affect. However, there is no evidence about the role of emotions in gay men and lesbian women with sexual problems. The present study analyzed affective states during sexual activity in homosexual and heterosexual men and women, with and without sexual problems. Participants in this study were 156 men and 168 women. A 2 (group) × 2 (sexual orientation) multivariate analysis of variance was performed. Participants completed a web-survey assessing sexual functioning and the Positive Affect-Negative Affect Scale. Findings indicated a main effect of group, with groups with sexual problems reporting significantly more negative and lower positive affect compared with men and women without sexual problems, regardless of sexual orientation. However, findings have also shown an interaction effect in the male sample with gay men, contrary to heterosexual men, reporting similar affective responses regardless of having a sexual dysfunction or not. Overall, findings emphasize the role of affective responses during sexual activity in men and women with sexual problems, suggesting the importance of addressing emotional responses in assessment and treatment of sexual problems in individuals with different sexual orientations.

Lymph node lesions in infectious mononucleosis (IM) show a marked histologic diversity. We report here three cases of IM lymphadenitis with histologic findings indistinguishable from those of toxoplasmic lymphadenitis. The histologic findings of the three cases presented here showed a histologic triad of toxoplasmic lymphadenitis, including (i) numerous lymphoid follicles with hyperplastic germinal centers; (ii) small clusters or single epithelioid histiocytes; and (iii) multiple foci of monocytoid B-cells. Moreover, all three lesions contained isolated or small clusters of epithelioid histiocytes within the hyperplastic germinal centers and the periphery of lymphoid follicles, which are the most specific histologic findings of toxoplasmic lymphadenitis. However, serologic findings confirmed EBV infection in all three cases. On in situ hybridization, numerous Epstein-Barr virus (EBV)-encoded small RNA (EBER)-positive cells were demonstrated in the germinal center, as well as in interfollicular areas in all three cases. Toxoplasmosis gondii infection was excluded in at least one case, based on serologic findings. Polymerase chain reaction analysis also demonstrated that there was no T. gondii DNA in the remaining two cases. Two of our three cases showed atypical clinical presentations, including an absence of atypical lymphocytosis in peripheral blood in two cases, age more than 30 years, and an absence of systemic symptoms in one case. It appears that previous descriptions emphasize the differential diagnostic problems between IM lymphadenitis and malignant lymphomas. However, from a therapeutic perspective, it is important to discriminate IM lymphadenitis from toxoplasmic lymphadenitis particularly in patients showing atypical clinical features. 2010 Elsevier GmbH.

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy.

Paroxysmal supraventricular tachycardia is a common dysrhythmia that occurs at all ages. Its management is determined by presenting symptoms and previous history of the patient. Patients present with a continuum of symptoms ranging from palpitations to syncope. The incidence of supraventricular tachycardia increases with age. To discuss the etiology, precipitating factors, and acute management of supraventricular tachycardia; and to discuss nodal reentry circuits and representative electrocardiographic findings. We present the case of an 84-year-old man with gallstone pancreatitis, choledolcholithiasis, and cholecystitis complicated by paroxysmal supraventricular tachycardia. We review this dysrhythmia, emphasizing its significance in elderly patients. Supraventricular tachycardia is a common dysrhythmia that can result in syncope or myocardial infarction. We present a case of an elderly man with new-onset atrioventricular (AV) nodal reentry tachycardia, possibly precipitated by overdrive of his autonomic nervous system due to pain and infection. As the percentage of the elderly in our population is growing rapidly and the incidence of AV nodal reentry tachycardia increases with age, emergency physicians should be familiar with this dysrhythmia-its etiology, precipitating factors, presentations, and treatment. It will present more frequently in the future. Published by Elsevier Inc.

Angioneurotic edema of the upper aerodigestive tract (AEUAT) often challenges the otolaryngologist with the decision of surgical intervention versus observation. To develop a logical approach to the evaluation and management of the airway in patients with AEUAT, emphasizing fiberoptic examination (FOE) findings. A computer-based retrospective review of all patients diagnosed with AEUAT was performed. The charts were reviewed for demographics, etiology, medical history, presentation, physical examination, imaging studies, intervention, and outcome. Findings on FOE as well as other covariants were statistically compared. Seventy patients with AEUAT were identified. The etiologies consisted of 24 cases of angiotensin converting enzyme inhibitor use (33%), 10 allergic reactions (17%), 1 hereditary (1.5%), and 35 idiopathic cases (48%). Fourteen patients underwent airway intervention, including 6 tracheotomies and 8 intubations. Of the 14 patients, 5 underwent emergent intervention before fiberoptic examination, 4 had laryngeal edema only, and 5 had both laryngeal and base of tongue edema. No patients with both laryngeal and base of tongue edema were observed. The remaining 52 patients were observed in a monitored setting and required no subsequent intervention. FOE is an invaluable tool in the assessment of the compromised airway in patients with angioneurotic edema Laryngeal edema alone is an ominous physical finding. When laryngeal and pharyngeal edema are present together, the physician should consider immediate intervention. Our findings indicate that symptoms, including stridor, hoarseness, and dysphagia, do correlate with disease severity; however, they must be confirmed with fiberoptic visualization. Although sound clinical judgment should always be exercised, we present our results in the management of the acute airway in angioneurotic edema.

2015-01-01

The present study was designed to determine the prevalence of premature loss of primary teeth and its effect on malocclusion in Eastern Province, Saudi Arabia. This is an observational, cross-sectional study that included 307 male children aged 9-11 years old. Clinical examinations were performed using a disposable sharp explorer, a UNC periodontal probe and a dental mirror. The samples were examined clinically to detect the following traits: Angle's classification of malocclusion, overjet, overbite, anterior open-bite, lateral open-bite, midline shift and cross-bite. Additionally, a dental caries examination was performed using WHO methods. Questionnaires in Arabic were coded and sent to the students' parents. The mean DMFT was 5.61 (SD = 3.01). The d-component was the highest, with a mean of 4 (SD = 2.83). Of the 307 children, it was found that 204 (66.4%) had a high DMFT score, which is defined as a score above 4. It was found that 156/307 (51%) children had premature loss of deciduous teeth. A high prevalence of premature loss of teeth was found in this study. This finding emphasizes the importance of increasing awareness levels about this issue and focuses attention on the need for more preventive efforts to maintain healthy and normal dentitions that would improve the masticatory function and aesthetics of individuals and the whole population. In addition, the findings emphasize the importance of the early detection of premature loss of primary teeth to prevent future malocclusion.

Previous studies have documented strategies to promote off-label use of drugs using journal publications and other means. Few studies have presented internal company communications that discussed financial reasons for manipulating the scholarly record related to off-label indications. The objective of this study was to build on previous studies to illustrate implementation of a publication strategy by the drug manufacturer for four off-label uses of gabapentin (Neurontin, Pfizer, Inc.): migraine prophylaxis, treatment of bipolar disorders, neuropathic pain, and nociceptive pain. We included in this study internal company documents, email correspondence, memoranda, study protocols and reports that were made publicly available in 2008 as part of litigation brought by consumers and health insurers against Pfizer for fraudulent sales practices in its marketing of gabapentin (see http://pacer.mad.uscourts.gov/dc/cgi-bin/recentops.pl?filename=saris/pdf/ucl%20opinion.pdf for the Court's findings).We reviewed documents pertaining to 20 clinical trials, 12 of which were published. We categorized our observations related to reporting biases and linked them with topics covered in internal documents, that is, deciding what should and should not be published and how to spin the study findings (re-framing study results to explain away unfavorable findings or to emphasize favorable findings); and where and when findings should be published and by whom. We present extracts from internal company marketing assessments recommending that Pfizer and Parke-Davis (Pfizer acquired Parke-Davis in 2000) adopt a publication strategy to conduct trials and disseminate trial findings for unapproved uses rather than an indication strategy to obtain regulatory approval. We show internal company email correspondence and documents revealing how publication content was influenced and spin was applied; how the company selected where trial findings would be presented or published; how publication of study results was delayed; and the role of ghost authorship. Taken together, the extracts we present from internal company documents illustrate implementation of a strategy at odds with unbiased study conduct and dissemination. Our findings suggest that Pfizer and Parke-Davis's publication strategy had the potential to distort the scientific literature, and thus misinform healthcare decision-makers.

Moving university hydrology education forward with community-based geoinformatics, data and modeling resources

Merwade, V.; Ruddell, B. L.

2012-08-01

In this opinion paper, we review recent literature related to data and modeling driven instruction in hydrology, and present our findings from surveying the hydrology education community in the United States. This paper presents an argument that that data and modeling driven geoscience cybereducation (DMDGC) approaches are essential for teaching the conceptual and applied aspects of hydrology, as a part of the broader effort to improve science, technology, engineering, and mathematics (STEM) education at the university level. The authors have undertaken a series of surveys and a workshop involving university hydrology educators to determine the state of the practice of DMDGC approaches to hydrology. We identify the most common tools and approaches currently utilized, quantify the extent of the adoption of DMDGC approaches in the university hydrology classroom, and explain the community's views on the challenges and barriers preventing DMDGC approaches from wider use. DMDGC approaches are currently emphasized at the graduate level of the curriculum, and only the most basic modeling and visualization tools are in widespread use. The community identifies the greatest barriers to greater adoption as a lack of access to easily adoptable curriculum materials and a lack of time and training to learn constantly changing tools and methods. The community's current consensus is that DMDGC approaches should emphasize conceptual learning, and should be used to complement rather than replace lecture-based pedagogies. Inadequate online material publication and sharing systems, and a lack of incentives for faculty to develop and publish materials via such systems, is also identified as a challenge. Based on these findings, we suggest that a number of steps should be taken by the community to develop the potential of DMDGC in university hydrology education, including formal development and assessment of curriculum materials, integrating lecture-format and DMDGC approaches, incentivizing the publication by faculty of excellent DMDGC curriculum materials, and implementing the publication and dissemination cyberinfrastructure necessary to support the unique DMDGC digital curriculum materials.

In this opinion paper, we review recent literature related to data and modeling driven instruction in hydrology, and present our findings from surveying the hydrology education community in the United States. This paper presents an argument that that Data and Modeling Driven Geoscience Cybereducation (DMDGC) approaches are valuable for teaching the conceptual and applied aspects of hydrology, as a part of the broader effort to improve Science, Technology, Engineering, and Mathematics (STEM) education at the university level. The authors have undertaken a series of surveys and a workshop involving the community of university hydrology educators to determine the state of the practice of DMDGC approaches to hydrology. We identify the most common tools and approaches currently utilized, quantify the extent of the adoption of DMDGC approaches in the university hydrology classroom, and explain the community's views on the challenges and barriers preventing DMDGC approaches from wider use. DMDGC approaches are currently emphasized at the graduate level of the curriculum, and only the most basic modeling and visualization tools are in widespread use. The community identifies the greatest barriers to greater adoption as a lack of access to easily adoptable curriculum materials and a lack of time and training to learn constantly changing tools and methods. The community's current consensus is that DMDGC approaches should emphasize conceptual learning, and should be used to complement rather than replace lecture-based pedagogies. Inadequate online material-publication and sharing systems, and a lack of incentives for faculty to develop and publish materials via such systems, is also identified as a challenge. Based on these findings, we suggest that a number of steps should be taken by the community to develop the potential of DMDGC in university hydrology education, including formal development and assessment of curriculum materials integrating lecture-format and DMDGC approaches, incentivizing the publication by faculty of excellent DMDGC curriculum materials, and implementing the publication and dissemination cyberinfrastructure necessary to support the unique DMDGC digital curriculum materials.

Ehlers-Danlos syndrome (EDS) includes a group of connective tissue disorders with abnormal collagen metabolism and a diverse clinical spectrum. We report two siblings with EDS who both presented with congenital diaphragmatic hernia (CDH). The elder sister suffered from recurrent diaphragmatic hernia twice and EDS was overlooked initially. Echocardiography as well as contrast-enhanced magnetic resonance angiography (MRA) showed dilatation of the pulmonary artery, and marked elongation and tortuosity of the aorta and its branches. A diagnosis of EDS was eventually established when these findings were coupled with the clinical features of hyperelastic skin. Her younger brother also had similar features. Thismore » report emphasizes that EDS may present as CDH in a small child which could easily be overlooked. Without appropriate surgery, diaphragmatic hernia might occur. Echocardiographic screening is recommended in patients with CDH. Contrast-enhanced MRA can be helpful in delineation of abnormally tortuous aortic great vessels that are an important clue to the early diagnosis of EDS.« less

Ectopic thyroid tissue may appear in any location along the trajectory of the thyroglossal duct from the foramen cecum to the mediastinum. Rarely, there is incomplete descent of the gland where the final resting point may be high resulting in sublingual ectopic thyroid tissue. Ectopic thyroid tissue carries a low risk of malignancy. Most recently reported neoplasms in ectopic thyroid tissue have been papillary carcinoma of thyroid. Individual case reports of clear cell type of follicular adenoma within the ectopic thyroid tissue have been described in the literature. We present a rare case of microfollicular follicular adenoma in an ectopic sublingual thyroid tissue presenting as submental swelling in a euthyroid 24-year-old Dravidian woman. Findings in this case emphasize that when confronted with a submental/sublingual mass lesion, the evaluation of thyroid function tests and ultrasonography of the neck should be included in a pre-operative workup.

This article aims to identify and critically assess qualitative intervention studies of rehabilitation processes that target young adults. By applying a meta-epistemological approach inspired by the works of Michel Foucault and Julia Kristeva, we examine how the included studies present qualitative knowledge and whether they adhere to their own stated principles of qualitative knowledge. Through their stated aims and theoretical framing, the articles draw attention to individual processes of meaning making. Nonetheless, we find that the articles to a great extent emphasize frequencies of the qualitative data they present. Individual processes and experiences are subject to subdivisions and categorization and transformed into manageable objects of knowledge. In conclusion, these studies, with one important exception, contribute to self-marginalization of the knowledge they themselves promote: They undermine the uniqueness of the qualitative knowledge they proclaim by focusing on frequency and the general patterns and categories encompassing the unique. © The Author(s) 2016.

Implicit Self-Importance in an Interpersonal Pronoun Categorization Task

Fetterman, Adam K.; Robinson, Michael D.; Gilbertson, Elizabeth P.

2014-01-01

Object relations theories emphasize the manner in which the salience/importance of implicit representations of self and other guide interpersonal functioning. Two studies and a pilot test (total N = 304) sought to model such representations. In dyadic contexts, the self is a “you” and the other is a “me”, as verified in a pilot test. Study 1 then used a simple categorization task and found evidence for implicit self-importance: The pronoun “you” was categorized more quickly and accurately when presented in a larger font size, whereas the pronoun “me” was categorized more quickly and accurately when presented in a smaller font size. Study 2 showed that this pattern possesses value in understanding individual differences in interpersonal functioning. As predicted, arrogant people scored higher in implicit self-importance in the paradigm. Findings are discussed from the perspective of dyadic interpersonal dynamics. PMID:25419089

Cognitive Load Selectively Interferes with Utilitarian Moral Judgment

Traditional theories of moral development emphasize the role of controlled cognition in mature moral judgment, while a more recent trend emphasizes intuitive and emotional processes. Here we test a dual-process theory synthesizing these perspectives. More specifically, our theory associates utilitarian moral judgment (approving of harmful actions that maximize good consequences) with controlled cognitive processes and associates non-utilitarian moral judgment with automatic emotional responses. Consistent with this theory, we find that a cognitive load manipulation selectively interferes with utilitarian judgment. This interference effect provides direct evidence for the influence of controlled cognitive processes in moral judgment, and utilitarian moral judgment more specifically. PMID:18158145

Statistics used in current nursing research.

Zellner, Kathleen; Boerst, Connie J; Tabb, Wil

2007-02-01

Undergraduate nursing research courses should emphasize the statistics most commonly used in the nursing literature to strengthen students' and beginning researchers' understanding of them. To determine the most commonly used statistics, we reviewed all quantitative research articles published in 13 nursing journals in 2000. The findings supported Beitz's categorization of kinds of statistics. Ten primary statistics used in 80% of nursing research published in 2000 were identified. We recommend that the appropriate use of those top 10 statistics be emphasized in undergraduate nursing education and that the nursing profession continue to advocate for the use of methods (e.g., power analysis, odds ratio) that may contribute to the advancement of nursing research.

Unsupervised learning in general connectionist systems.

PubMed

Dente, J A; Mendes, R Vilela

1996-01-01

There is a common framework in which different connectionist systems may be treated in a unified way. The general system in which they may all be mapped is a network which, in addition to the connection strengths, has an adaptive node parameter controlling the output intensity. In this paper we generalize two neural network learning schemes to networks with node parameters. In generalized Hebbian learning we find improvements to the convergence rate for small eigenvalues in principal component analysis. For competitive learning the use of node parameters also seems useful in that, by emphasizing or de-emphasizing the dominance of winning neurons, either improved robustness or discrimination is obtained.

As the number of children with Zika virus-related complications grows, the long-term developmental trajectory and its effects on families are unknown. We present the first known case of congenital Zika syndrome seen at our institution with significant fundus findings. A 3-day-old Hispanic baby girl presented with severe microcephaly of 24 cm and temperature instability at birth. Her mother had traveled to Honduras early in pregnancy and testing of amniotic fluid was positive for Zika virus via polymerase chain reaction. A dilated fundus examination was significant for bilateral severe colobomatous chorioretinal atrophy of the macula and pigmentary changes. Neonatal magnetic resonance imaging revealed diffuse lissencephaly with decreased brain volume, atrophic corpus callosum and brainstem, periventricular calcifications, and ventriculomegaly of the lateral ventricles. Our patient, who presented with the first known case of congenital Zika syndrome in Northern Florida, demonstrated profound bilateral colobomatous chorioretinal atrophy of the macula. The ophthalmologic findings along with severe microcephaly emphasize the neurotropism of the Zika virus, and ultimately are indicative of poor developmental and visual prognosis for affected infants. With the increased prevalence of Zika virus, ophthalmologists should be aware of the associated findings and the importance of an eye-screening examination with a dilated fundus examination within 1 month of life of infants in which congenital Zika syndrome is suspected. A multidisciplinary care approach is essential for the care of affected infants and their families.

Cholinesterases in Gambusia yucatana: Biochemical Characterization and its Relationship with Sex and Total Length.

Since several reports have indicated that cholinesterases (ChE) type and distribution is species specific and that in some species there is a relationship among gender, size and ChE activities, characterization has been suggested. The aim of the present study was to characterize the ChE present in head and muscle of Gambusia yucatana (using selective substrates and inhibitors) and to find its relationship with total length or gender. Results indicated that the ChE present in G. yucatana is an acetylcholinesterase (AChE) with high sensitivity to BW284C51 and an atypical smaller Km with butyrylthiocholine. Scatterplots indicated that there is no linearity between total length and AChE in male or female wild mosquitofish. There were no sex differences in AChE activities. Results indicated significant differences between a single collection site in the Yucatan peninsula and depurated organisms. This study emphasized the importance of characterizing ChE before usage in biomonitoring.

The variational method in quantum mechanics: an elementary introduction

NASA Astrophysics Data System (ADS)

Borghi, Riccardo

2018-05-01

Variational methods in quantum mechanics are customarily presented as invaluable techniques to find approximate estimates of ground state energies. In the present paper a short catalogue of different celebrated potential distributions (both 1D and 3D), for which an exact and complete (energy and wavefunction) ground state determination can be achieved in an elementary way, is illustrated. No previous knowledge of calculus of variations is required. Rather, in all presented cases the exact energy functional minimization is achieved by using only a couple of simple mathematical tricks: ‘completion of square’ and integration by parts. This makes our approach particularly suitable for undergraduates. Moreover, the key role played by particle localization is emphasized through the entire analysis. This gentle introduction to the variational method could also be potentially attractive for more expert students as a possible elementary route toward a rather advanced topic on quantum mechanics: the factorization method. Such an unexpected connection is outlined in the final part of the paper.

To provide a review of the current excellent research published in the field of Consumer Health Informatics. We searched MEDLINE® and WEB OF SCIENCE® databases for papers published in 2013 in relation with Consumer Health Informatics. The authors identified 16 candidate best papers, which were then reviewed by four reviewers. Five out of the 16 candidate papers were selected as best papers. One paper presents the key features of a system to automate the collection of web-based social media content for subsequent semantic annotation. This paper emphasizes the importance of mining social media to collect novel data from which new findings in drug abuse research were uncovered. The second paper presents a practical method to predict how a community structure would impact the spreading of information within the community. The third paper presents a method for improving the quality of online health communities. The fourth presents a new social network to allow the monitoring of the evolution of individuals' health status and diagnostic deficiencies, difficulties or barriers in rehabilitation. The last paper reports on teenage patients' perception on privacy and social media. Selected papers not only show the value of using social media in the medical field but how to use these media to detect emergent diseases or risks, inform patients, promote disease prevention, and follow patients' opinion on healthcare resources.

A 24-year-old Japanese woman developed anterocollis, weakness of the proximal arms, and subsequent cognitive impairment. A neurological examination revealed amyotrophic lateral sclerosis (ALS) without a family history. Systemic muscle atrophy progressed rapidly. Cerebral MRI clearly exhibited high signal intensities along the bilateral pyramidal tracts. An analysis of the FUS gene revealed a heterozygous two-base pair deletion, c.1507-1508delAG (p.G504WfsX515). A subset of juvenile-onset familial/sporadic ALS cases with FUS gene mutations reportedly demonstrates mental retardation or learning difficulty. Our study emphasizes the importance of conducting a FUS gene analysis in juvenile-onset ALS cases, even when no family occurrence is confirmed.

Chronic myelogenous leukemia represents the poster child of successful precision medicine in cancer, with amazing survival results achieved with targeted tyrosine kinase inhibitors (TKIs) in many patients with chronic-phase disease. Unfortunately, however, this good news has not extended to patients in blast crisis, for whom survival has not clearly been improved with TKIs. During his presentation at the NCCN 21st Annual Conference, Jerald P. Radich, MD, briefly explored the biology behind advanced-stage disease and several of the molecular findings in disease progression. He also reviewed some of the therapeutic options in advanced disease, emphasizing that transplantation, although fraught with some difficulties, offers the best long-term prognosis for patients in blast crisis.

Innovation is the engine of scientific progress, yet we do not train public health students to think creatively. I present the key concepts within an evidence-based method currently taught at the University of Texas. Habitual thought patterns involve deeply held framed expectations. Finding alternatives generates originality. Because frame breaking is difficult, a series of innovation heuristics and tools are offered including enhancing observation, using analogies, changing point of view, juggling opposites, broadening perspective, reversal, reorganization and combination, and getting the most from groups. Gaining cognitive attributes such as nonjudgment, willingness to question, mindfulness, and plasticity is also emphasized. Students completing the class demonstrate substantial increases on a standardized test of idea fluency and originality, more joyful attitudes toward science, and more pluralistic approaches.

This study examined the importance of body image evaluation and investment to predict dietary restraint in men (N = 272). Measures of physical activity, evaluation, investment and dietary restraint were completed. A hierarchical regression was conducted to predict dietary restraint from physical activity and body mass index (entered on the first step), body image evaluation (entered on the second step) and investment (entered on the final step). The overall regression was significant, F(4, 271) = 15.12, p < .001, R (2) adj = .17). Body mass index, physical activity and body image investment were significant positive predictors of dietary restraint. The present findings emphasize measuring body image investment. © The Author(s) 2015.

Here, we present the first unconstrained nonadiabatic molecular dynamics (NAMD) simulations of photocatalytic water oxidation by small hydrated TiO 2 nanoparticles using Tully surface hopping and time-dependent density functional theory. The results indicate that ultrafast electron–proton transfer from physisorbed water to the photohole initiates the photo-oxidation on the S 1 potential energy surface. The new mechanism readily explains the observation of mobile hydroxyl radicals in recent experiments. Two key driving forces for the photo-oxidation reaction are identified: localization of the electron–hole pair and stabilization of the photohole by hydrogen bonding interaction. Our findings illustrate the scope of recent advances inmore » NAMD methods and emphasize the importance of explicit simulation of electronic excitations.« less

Guillen, E O; Barr, S I

1994-09-01

This study was designed to characterize nutrition and fitness messages presented between 1970-1990 in a magazine for adolescent women; to evaluate whether these messages changed over time; and to assess the body shape portrayed as desirable, and whether this changed over time. A data collection form was developed to code nutrition and fitness-related written items, advertisements and recipes, and the page coverage allocated to these items. Body shape was assessed by measuring bust:waist and hip:waist ratios of photographs of models wearing bathing suits or underwear. Magazines from even years between 1970-1990 (n = 132) were coded. Both nutrition-related and fitness-related coverage emphasized weight loss and physical appearance. Half the major nutrition-related articles presented a weight-loss plan, and weight loss was frequently addressed in other nutrition articles. The primary reasons presented for following a nutrition of fitness plan were to lose weight and become more attractive. Statements that the product or service would promote weight loss were found in 47% of nutrition-related advertisements. Nutrition coverage did not exhibit a net change over time, whereas fitness coverage increased (F = 6.6, p < .005), and the ratio of nutrition: fitness coverage changed from 10:1 in 1970 to 0.75:1 in 1990. Models' body shapes were less curvaceous than those in magazines for adult women, and the hip:waist ratio decreased over time (F = 7.3, p < .01). The nutrition and fitness messages in this magazine for adolescent women emphasize body shape and appearance, similar to findings from adult women's magazines, and contribute to the cultural milieu in which thinness is an expectation for women. Between 1970-1990, the emphasis on fitness increased, and the body shape of models tended to become more linear.

Context change explains resurgence after the extinction of operant behavior

PubMed Central

Trask, Sydney; Schepers, Scott T.; Bouton, Mark E.

2016-01-01

Extinguished operant behavior can return or “resurge” when a response that has replaced it is also extinguished. Typically studied in nonhuman animals, the resurgence effect may provide insight into relapse that is seen when reinforcement is discontinued following human contingency management (CM) and functional communication training (FCT) treatments, which both involve reinforcing alternative behaviors to reduce behavioral excess. Although the variables that affect resurgence have been studied for some time, the mechanisms through which they promote relapse are still debated. We discuss three explanations of resurgence (response prevention, an extension of behavioral momentum theory, and an account emphasizing context change) as well as studies that evaluate them. Several new findings from our laboratory concerning the effects of different temporal distributions of the reinforcer during response elimination and the effects of manipulating qualitative features of the reinforcer pose a particular challenge to the momentum-based model. Overall, the results are consistent with a contextual account of resurgence, which emphasizes that reinforcers presented during response elimination have a discriminative role controlling behavioral inhibition. Changing the “reinforcer context” at the start of testing produces relapse if the organism has not learned to suppress its responding under conditions similar to the ones that prevail during testing.

Background: Self-esteem is known to be one of the most important markers of successful aging. Older people's self-esteem is influenced by several factors that particularly may be health related. Therefore, this study aimed to explore some important general health-related predictors of the older people's self-esteem. Materials and Methods: In this study, 200 people, aged 65 years and older, who referred to health care centers were selected through stratified random sampling method. Data were collected by using Rosenberg's self-esteem scale and the 28-item Goldberg's general health questionnaire. Data were analyzed by Pearson's coefficient tests and multiple regression analysis. Results: Findings showed that the entered predictor variables accounted for 49% of the total variance (R2) of self-esteem in the model (P < 0.001, F4,195 = 46.717). Three out of the four predictor variables including somatic signs, anxiety/insomnia, and depression, significantly predicted the self-esteem. The results emphasized on the determinant role of both physical (somatic signs) and mental (anxiety/insomnia and depression) aspects of health in older patients’ self-esteem. Conclusions: The significant general health-related predictors found in the present study emphasize on some of the significant points that should be considered in planning for improving older patients’ self-esteem.

Land-use planning has triggered debates on social and environmental values, in which two key questions will be faced: one is how to see different planning simulation results instantaneously and apply the results back to interactively assist planning work; the other is how to ensure that the planning simulation result is scientific and accurate. To answer these questions, the objective of this paper is to analyze whether and how a bridge can be built between qualitative and quantitative approaches for land-use planning work and to find out a way to overcome the gap that exists between the ability to construct computer simulation models to aid integrated land-use plan making and the demand for them by planning professionals. The study presented a theoretical framework of land-use planning based on scenario analysis (SA) method and multiagent system (MAS) simulation integration and selected freshwater wetlands in the Sanjiang Plain of China as a case study area. Study results showed that MAS simulation technique emphasizing quantitative process effectively compensated for the SA method emphasizing qualitative process, which realized the organic combination of qualitative and quantitative land-use planning work, and then provided a new idea and method for the land-use planning and sustainable managements of land resources.

In the framework of this study, target identification and localization of differentiation patterns by means of dielectric spectroscopy is presented. Here, a primary pre-osteoblastic bone marrow-derived MBA-15 cellular system was used to study the variations in the dielectric properties of mesenchymal stem cells while exposed to differentiation regulators. Using the fundamentals of mixed dielectric theories combined with finite numerical tools, the permittivity spectra of MBA-15 cell suspensions have been uniquely analyzed after being activated by steroid hormones to express osteogenic phenotypes. Following the spectral analysis, significant variations were revealed in the dielectric properties of the activated cells in comparison to the untreated populations. Based on the differentiation patterns of MBA-15, the electrical modifications were found to be highly correlated with the activation of specific cellular mechanisms which directly react to the hormonal inductions. In addition, by describing the dielectric dispersion in terms of transfer functions, it is shown that the spectral perturbations are well adapted to variations in the electrical characteristics of the cells. The reported findings vastly emphasize the tight correlation between the cellular and electrical state of the differentiated cells. It therefore emphasizes the vast abilities of impedance-based techniques as potential screening tools for stem cell analysis. Copyright 2009 Elsevier B.V. All rights reserved.

Self-esteem is known to be one of the most important markers of successful aging. Older people's self-esteem is influenced by several factors that particularly may be health related. Therefore, this study aimed to explore some important general health-related predictors of the older people's self-esteem. In this study, 200 people, aged 65 years and older, who referred to health care centers were selected through stratified random sampling method. Data were collected by using Rosenberg's self-esteem scale and the 28-item Goldberg's general health questionnaire. Data were analyzed by Pearson's coefficient tests and multiple regression analysis. Findings showed that the entered predictor variables accounted for 49% of the total variance (R(2)) of self-esteem in the model (P < 0.001, F4,195 = 46.717). Three out of the four predictor variables including somatic signs, anxiety/insomnia, and depression, significantly predicted the self-esteem. The results emphasized on the determinant role of both physical (somatic signs) and mental (anxiety/insomnia and depression) aspects of health in older patients' self-esteem. The significant general health-related predictors found in the present study emphasize on some of the significant points that should be considered in planning for improving older patients' self-esteem.

Applications and toxicity of graphene family nanomaterials and their composites

Singh, Zorawar

2016-01-01

Graphene has attracted much attention of scientific community due to its enormous potential in different fields, including medical sciences, agriculture, food safety, cancer research, and tissue engineering. The potential for widespread human exposure raises safety concerns about graphene and its derivatives, referred to as graphene family nanomaterials (GFNs). Due to their unique chemical and physical properties, graphene and its derivatives have found important places in their respective application fields, yet they are being found to have cytotoxic and genotoxic effects too. Since the discovery of graphene, a number of researches are being conducted to find out the toxic potential of GFNs to different cell and animal models, finding their suitability for being used in new and varied innovative fields. This paper presents a systematic review of the research done on GFNs and gives an insight into the mode and action of these nanosized moieties. The paper also emphasizes on the recent and up-to-date developments in research on GFNs and their nanocomposites for their toxic effects. PMID:27051278

Determinant quantum Monte Carlo study of the two-dimensional single-band Hubbard-Holstein model

Johnston, S.; Nowadnick, E. A.; Kung, Y. F.; ...

2013-06-24

Here, we performed numerical studies of the Hubbard-Holstein model in two dimensions using determinant quantum Monte Carlo (DQMC). We also present details of the method, emphasizing the treatment of the lattice degrees of freedom, and then study the filling and behavior of the fermion sign as a function of model parameters. We find a region of parameter space with large Holstein coupling where the fermion sign recovers despite large values of the Hubbard interaction. This indicates that studies of correlated polarons at finite carrier concentrations are likely accessible to DQMC simulations. We then restrict ourselves to the half-filled model andmore » examine the evolution of the antiferromagnetic structure factor, other metrics for antiferromagnetic and charge-density-wave order, and energetics of the electronic and lattice degrees of freedom as a function of electron-phonon coupling. From this we find further evidence for a competition between charge-density-wave and antiferromagnetic order at half- filling.« less

Investigating the encoding-retrieval match in recognition memory: effects of experimental design, specificity, and retention interval.

PubMed

Dewhurst, Stephen A; Knott, Lauren M

2010-12-01

Five experiments investigated the encoding-retrieval match in recognition memory by manipulating read and generate conditions at study and at test. Experiments 1A and 1B confirmed previous findings that reinstating encoding operations at test enhances recognition accuracy in a within-groups design but reduces recognition accuracy in a between-groups design. Experiment 2A showed that generating from anagrams at study and at test enhanced recognition accuracy even when study and test items were generated from different anagrams. Experiment 2B showed that switching from one generation task at study (e.g., anagram solution) to a different generation task at test (e.g., fragment completion) eliminated this recognition advantage. Experiment 3 showed that the recognition advantage found in Experiment 1A is reliably present up to 1 week after study. The findings are consistent with theories of memory that emphasize the importance of the match between encoding and retrieval operations.

Effect of noisy stimulation on neurobiological sensitization systems and its role for normal and pathological physiology

NASA Astrophysics Data System (ADS)

Huber, Martin; Braun, Hans; Krieg, J.\\:Urgen-Christian

2004-03-01

Sensitization is discussed as an important phenomenon playing a role in normal physiology but also with respect to the initiation and progression of a variety of neuropsychiatric disorders such as epilepsia, substance-related disorders or recurrent affective disorders. The relevance to understand the dynamics of sensitization phenomena is emphasized by recent findings that even single stimulations can induce longlasting changes in biological systems. To address specific questions associated with the sensitization dynamics, we use a computational approach and develop simple but physiologically-plausible models. In the present study we examine the effect of noisy stimulation on sensitization development in the model. We consider sub- and suprathresold stimulations with varying noise intensities and determine as response measures the (i) absolute number of stimulus-induced sensitzations and (ii) the temporal relsation of stimulus-sensitization coupling. The findings indicate that stochastic effects including stochastic resonance might well contribute to the physiology of sensitization mechanisms under both nomal and pathological conditions.

Chinese mental illness narratives: controlling the spirit.

PubMed

Ramsay, Guy

2009-01-01

Through analysis of local level narrative themes and linguistic features and their attendant narrative 'domains' and emotive content, this study explicates the discursive forms of Chinese personal narratives about mental illness published in a psychoeducational volume in mainland China. The cultural phenomena underpinning the explicated discursive forms are considered. The study finds that the Chinese mental illness narratives emphasize the problematic nature of the illness experience for the individual concerned, as well as the importance of gaining control over the personal and social disembodiment that mental illness brings about. The language of medicine presents as a dominant linguistic feature of the texts. Narrative authors appear to respond to their illness experience by negotiating and utilizing social relationships and support structures and through active medical intercession. As such, their narratives appear deeply culturally marked despite their psychoeducational intent and institutional context of publication. The study findings bear out the call for more attention to be given to the cultural dimension when analysing illness narratives.

Being a team leader: newly registered nurses relate their experiences.

PubMed

Ekström, Louise; Idvall, Ewa

2015-01-01

This paper presents a study that explores how newly qualified registered nurses experience their leadership role in the ward-based nursing care team. A nurse's clinical leadership affects the quality of care provided. Newly qualified nurses experience difficulties during the transition period from student to qualified professional and find it challenging to lead nursing care. Twelve nurses were interviewed and the transcribed texts analysed using qualitative content analysis to assess both manifest and latent content. Five themes were identified: feeling stranded; forming well-functioning teams; learning to lead; having the courage, strength, and desire to lead; and ensuring appropriate care. The findings indicate that many factors limit nurses' leadership but some circumstances are supportive. The leadership prerequisites for newly registered nurses need to improve, emphasizing different ways to create a supportive atmosphere that promotes professional development and job satisfaction. To increase nurse retention and promote quality of care, nurse managers need to clarify expectations and guide and support newly qualified nurses in a planned way. © 2013 John Wiley & Sons Ltd.

2012-01-01

Guided by a risk and resilience framework, this study used a prospective longitudinal, multiple-reporter design to examine how social support from a mother figure during pregnancy interacted with Mexican-origin adolescent mothers’ self-esteem to inform their parenting efficacy when their children were 10 months old. Using reports of perceived social support by adolescent mothers (Mage = 16.24, SD =099) and their mother figures (Mage = 40.84, SD = 7.04) in 205 dyads, and controlling for demographic factors (i.e., adolescent age, adolescent nativity, family income, mothers’ educational attainment, adolescent-mother coresidence) and adolescents’ social support from a significant other, findings indicated that social support during pregnancy was positively associated with adolescent mothers’ future parenting efficacy when adolescent mothers had relatively lower self-esteem. Findings were consistent for adolescents’ and mothers’ reports, and emphasize the value of social support from a mother figure among adolescent mothers with lower self-esteem. Implications for interventions are presented. PMID:24244049

How instructors' emotional expressions shape students' learning performance: the roles of anger, happiness, and regulatory focus.

PubMed

van Doorn, Evert A; van Kleef, Gerben A; van der Pligt, Joop

2014-06-01

How do instructors' emotional expressions influence students' learning performance? Scholars and practitioners alike have emphasized the importance of positive, nurturing emotions for successful learning. However, teachers may sometimes lose their temper and express anger at their pupils. Drawing on emotions as social information (EASI) theory, we hypothesized that expressions of anger can benefit learning performance. In Experiment 1, participants who were confronted with an angry instructor exhibited more accurate recognition of word pairs after a week of learning, compared with those who were confronted with a happy instructor. In Experiment 2, we conceptually replicated this effect on a recall task, but only among participants in a promotion rather than prevention focus. Present findings thus show, for the 1st time, that instructor anger can enhance students' performance. Findings are consistent with a conceptualization of emotion as social information and call into question the generally endorsed positivity paradigm.

Symptom Dimensions in Obsessive-Compulsive Disorder: Phenomenology and Treatment Outcomes with Exposure and Ritual Prevention

PubMed Central

Williams, Monnica T.; Mugno, Beth; Franklin, Martin; Faber, Sonya

2014-01-01

Obsessive-compulsive disorder (OCD) is a severe condition with varied symptom presentations. The cognitive-behavioral treatment with the most empirical support is currently exposure and ritual prevention (EX/RP); however, clinical impression and some empirical data suggest that certain OCD symptoms are more responsive to treatment than others. Prior work identifying symptom dimensions within OCD is discussed, including epidemiological findings, factor analytic studies, and biological findings. Symptom dimensions most reliably identified include contamination/cleaning, doubt about harm/checking, symmetry/ordering, and unacceptable thoughts/mental rituals. The phenomenology of each of these subtypes is described and research literature is summarized, emphasizing the differential effects of EX/RP and its variants on each of these primary symptom dimensions. To date it appears that EX/RP is an effective treatment for the various OCD dimensions, although not all dimensions have been adequately studied (i.e., symmetry and ordering). Modifications to treatment may be warranted for some types of symptoms. Clinical implications and directions for future research are discussed. PMID:23615340

Segmental arterial mediolysis: findings at computed tomography angiography.

García-Barquín, P; Bilbao, J I; Quílez, A; Aragón, M S; Vivas, I

To review the principal findings on computed tomography angiography for segmental arterial mediolysis, and to emphasize the points that help to differentiate it from other vasculopathies such as vasculitis. We also review the protocols for follow-up and the various treatment options. Segmental arterial mediolysis is a rare disease that is defined as a non-atherosclerotic, non-hereditary, and non-inflammatory vasculopathy characterized by lysis of the medial layer of the arterial wall. It should be suspected in middle-aged patients with aneurysms, dissections, or spontaneous ruptures of visceral arteries of unknown etiology who do not fulfill the clinical and laboratory criteria for vasculitis. The arteries of the abdominal organs are the most commonly affected, including the arteries of the celiac trunk and the superior and inferior mesenteric arteries. Radiologically, segmental arterial mediolysis can present as arterial dilation; single or multiple, saccular or fusiform aneurysms; stenoses; or dissections. Copyright © 2016 SERAM.

Organic synthesis provides opportunities to transform drug discovery

NASA Astrophysics Data System (ADS)

Blakemore, David C.; Castro, Luis; Churcher, Ian; Rees, David C.; Thomas, Andrew W.; Wilson, David M.; Wood, Anthony

2018-04-01

Despite decades of ground-breaking research in academia, organic synthesis is still a rate-limiting factor in drug-discovery projects. Here we present some current challenges in synthetic organic chemistry from the perspective of the pharmaceutical industry and highlight problematic steps that, if overcome, would find extensive application in the discovery of transformational medicines. Significant synthesis challenges arise from the fact that drug molecules typically contain amines and N-heterocycles, as well as unprotected polar groups. There is also a need for new reactions that enable non-traditional disconnections, more C-H bond activation and late-stage functionalization, as well as stereoselectively substituted aliphatic heterocyclic ring synthesis, C-X or C-C bond formation. We also emphasize that syntheses compatible with biomacromolecules will find increasing use, while new technologies such as machine-assisted approaches and artificial intelligence for synthesis planning have the potential to dramatically accelerate the drug-discovery process. We believe that increasing collaboration between academic and industrial chemists is crucial to address the challenges outlined here.

Principles and tools for collaborative entity-based intelligence analysis.

Bier, Eric A; Card, Stuart K; Bodnar, John W

2010-01-01

Software tools that make it easier for analysts to collaborate as a natural part of their work will lead to better analysis that is informed by more perspectives. We are interested to know if software tools can be designed that support collaboration even as they allow analysts to find documents and organize information (including evidence, schemas, and hypotheses). We have modified the Entity Workspace system, described previously, to test such designs. We have evaluated the resulting design in both a laboratory study and a study where it is situated with an analysis team. In both cases, effects on collaboration appear to be positive. Key aspects of the design include an evidence notebook optimized for organizing entities (rather than text characters), information structures that can be collapsed and expanded, visualization of evidence that emphasizes events and documents (rather than emphasizing the entity graph), and a notification system that finds entities of mutual interest to multiple analysts. Long-term tests suggest that this approach can support both top-down and bottom-up styles of analysis.

The role of "evidence" in recovery from mental illness.

PubMed

Tanenbaum, Sandra J

2006-12-01

Evidence-based practice (EBP), a derivative of evidence-based medicine (EBM), is ascendant in the United States' mental health system; the findings of randomized controlled trials and other experimental research are widely considered authoritative in mental health practice and policy. The concept of recovery from mental illness is similarly pervasive in mental health programming and advocacy, and it emphasizes consumer expertise and self-determination. What is the relationship between these two powerful and potentially incompatible forces for mental health reform? This paper identifies four attempts, in the mental health literature, to delineate the role of "evidence" in recovery. One is the strong version of evidence-based practice-an applied science model-and three others address weaknesses in the first by limiting the authority of probabilistic findings. The paper also offers a fifth version, based on the concept of communicative accountability, which is derived from Habermas' work on communicative action. The fifth version responds to the other four and emphasizes learning, disclosure and respect in clinical and other helping relationships.

Exploring multivariate representations of indices along linear geographic features

NASA Astrophysics Data System (ADS)

Bleisch, Susanne; Hollenstein, Daria

2018-05-01

A study of the walkability of a Swiss town required finding suitable representations of multivariate geographical da-ta. The goal was to represent multiple indices of walkability concurrently and visualizing the data along the street network it relates to. Different indices of pedestrian friendliness were assessed for short street sections and then mapped to an overlaid grid. Basic and composite glyphs were designed using square- or triangle-areas to display one to four index values concurrently within the grid structure. Color was used to indicate different indices. Implement-ing visualizations for different combinations of index sets, we find that single values can be emphasized or de-emphasized by selecting the color scheme accordingly and that different color selections either allow perceiving sin-gle values or overall trends over the evaluated area. Values for up to four indices can be displayed in combination within the resulting geovisualizations and the underlying gridded road network references the data to its real world locations.

Bureaucratization and medical professionals' values: A cross-national analysis.

PubMed

Racko, Girts

2017-05-01

Understanding the impact of the bureaucratization of governance systems on the occupational values of medical professionals is a fundamental concern of the sociological research of healthcare professions. While previous studies have examined the impact of bureaucratized management, organizations, and healthcare fields on medical professionals' values, there is a lack of cross-national research on the normative impact of the bureaucratized systems of national governance. Using the European Social Survey data for 29 countries, this study examines the impact of the bureaucratization of national governance systems on the occupational values of medical professionals. The findings indicate that medical professionals who are employed in countries with the more bureaucratized systems of national governance are less concerned with openness to change values, that emphasize autonomy and creativity, and self-transcendence values, that emphasize common good. The findings also indicate that the negative effect of the bureaucratization of national governance on the openness to change values is stronger for medical professionals in more bureaucratized organizations with more rationalized administration systems.

Does a Culture of Happiness Increase Rumination Over Failure?

PubMed

McGuirk, Lucy; Kuppens, Peter; Kingston, Rosemary; Bastian, Brock

2017-07-17

Promoting happiness within society is good for health, but could the overpromotion of happiness have a downside? Across 2 studies, we investigate 2 emotion norms associated with an emphasis on happiness-the importance of (a) seeking positive emotion, and (b) avoiding negative emotion-and whether these norms have implications for how people respond to, and seek to regulate, their negative emotional experiences. In Study 1, we used an experimental design to show that emphasizing the importance of happiness increased rumination in response to failure. In Study 2, we drew on cross-sectional evidence to investigate the other side of this equation, finding that emphasizing the importance of not experiencing negative emotional states (e.g., depression and anxiety) was also associated with increased rumination, and that this had downstream consequences for well-being. Together, the findings suggest that the overpromotion of happiness, and, in turn, the felt social pressure not to experience negative emotional states, has implications for maladaptive responses to negative emotional experiences.

Novel insights into human lactation as a driver of infant formula development.

PubMed

Lönnerdal, Bo

2010-01-01

Progress in research on human lactation and breast milk has advanced our knowledge about the significance of breast milk for the recipient infant and the effects of various components on long-term outcomes. Recent findings have expanded our knowledge in this area. Several growth factors and cytokines are present in breast milk and their capacity to persist in the infant gut and exert their activities is likely to affect maturation of immune function, possibly affecting the development of oral tolerance. A proper balance of polyunsaturated fatty acids (n-3/n-6 ratio) may also be of significance for allergy prevention in children, emphasizing the need for the mother to achieve a balance of these fatty acids in her diet. The recent findings that specific strains of bacteria are present in breast milk and act as probiotics in the early colonization of the infant gut and that human milk oligosaccharides are specific substrates for these probiotic strains may not only affect the defense against pathogens, but also affect energy utilization and development of obesity. Previously neglected milk fat globule membranes contain several components involved in protection against infection and may be an additional arm in the multifaceted shield that breastfed infants have developed against bacterial and viral antagonists. All these findings have implications for development of improved infant formulae. Copyright © 2010 S. Karger AG, Basel.

Recent studies have yielded initial evidence for an association between Internet Use Disorder (IUD), empathy, and life satisfaction. In the present study we sought to replicate these previous findings, and then to extend this research by also examining the relationship between empathy, life satisfaction, and the related phenomenon of Smartphone Use Disorder (SUD). The present study included independent samples from China (N = 612, 162 females) and Germany (N = 304, 207 females), with the same set of questionnaires administered to both samples. IUD was measured with Pawlikowski's s-IAT and SUD was assessed with the short version of Kwon's Smartphone Addiction Scale. The Interpersonal Reactivity Index (IRI) was used to assess individual differences in empathy. Please note that for the German sample data on the empathy quotient (EQ) are also available. Life satisfaction data were collected using items from the SOEP-Questionnaire (Socio-Economic Panel, Germany). In both of our samples we replicated previous findings showing the association between higher IUD, lower empathy, and lower life satisfaction scores. In addition, individuals with higher SUD showed higher scores on the IRI Personal Distress scale in China and Germany, while further associations between IRI dimensions and SUD were only found in the Chinese sample. Personal Distress is known to be highly correlated with the personality trait of Neuroticism, hence higher stress/negative emotionality in tense social situations is related to SUD. In the present study we confirm earlier findings showing the relationship between empathy, life satisfaction, and IUD, and extend some of these findings to SUD. We also emphasize the importance of cross-cultural studies when investigating IUD/SUD in the context of empathy and life satisfaction. PMID:29636714

Effects of Individual Differences in Working Memory on Plan Presentational Choices

PubMed Central

Tintarev, Nava; Masthoff, Judith

2016-01-01

This paper addresses research questions that are central to the area of visualization interfaces for decision support: (RQ1) whether individual user differences in working memory should be considered when choosing how to present visualizations; (RQ2) how to present the visualization to support effective decision making and processing; and (RQ3) how to evaluate the effectiveness of presentational choices. These questions are addressed in the context of presenting plans, or sequences of actions, to users. The experiments are conducted in several domains, and the findings are relevant to applications such as semi-autonomous systems in logistics. That is, scenarios that require the attention of humans who are likely to be interrupted, and require good performance but are not time critical. Following a literature review of different types of individual differences in users that have been found to affect the effectiveness of presentational choices, we consider specifically the influence of individuals' working memory (RQ1). The review also considers metrics used to evaluate presentational choices, and types of presentational choices considered. As for presentational choices (RQ2), we consider a number of variants including interactivity, aggregation, layout, and emphasis. Finally, to evaluate the effectiveness of plan presentational choices (RQ3) we adopt a layered-evaluation approach and measure performance in a dual task paradigm, involving both task interleaving and evaluation of situational awareness. This novel methodology for evaluating visualizations is employed in a series of experiments investigating presentational choices for a plan. A key finding is that emphasizing steps (by highlighting borders) can improve effectiveness on a primary task, but only when controlling for individual variation in working memory. PMID:27899905

There is limited understanding of why routine immunization (RI) coverage improves in some settings in Africa and not in others. Using a grounded theory approach, we conducted in-depth case studies to understand pathways to coverage improvement by comparing immunization programme experience in 12 districts in three countries (Ethiopia, Cameroon and Ghana). Drawing on positive deviance or assets model techniques we compared the experience of districts where diphtheria–tetanus–pertussis (DTP3)/pentavalent3 (Penta3) coverage improved with districts where DTP3/Penta3 coverage remained unchanged (or steady) over the same period, focusing on basic readiness to deliver immunization services and drivers of coverage improvement. The results informed a model for immunization coverage improvement that emphasizes the dynamics of immunization systems at district level. In all districts, whether improving or steady, we found that a set of basic RI system resources were in place from 2006 to 2010 and did not observe major differences in infrastructure. We found that the differences in coverage trends were due to factors other than basic RI system capacity or service readiness. We identified six common drivers of RI coverage performance improvement—four direct drivers and two enabling drivers—that were present in well-performing districts and weaker or absent in steady coverage districts, and map the pathways from driver to improved supply, demand and coverage. Findings emphasize the critical role of implementation strategies and the need for locally skilled managers that are capable of tailoring strategies to specific settings and community needs. The case studies are unique in their focus on the positive drivers of change and the identification of pathways to coverage improvement, an approach that should be considered in future studies and routine assessments of district-level immunization system performance.

Performance perceptions and self-focused attention predict post-event processing after a real-life social performance situation.

PubMed

Helbig-Lang, Sylvia; Poels, Vanja; Lincoln, Tania M

2016-11-01

Cognitive approaches to social anxiety suggest that an excessive brooding about one's performance in a social situation (post-event processing; PEP) is involved in the maintenance of anxiety. To date, most studies investigating PEP were conducted in laboratory settings. The present study sought to replicate previous findings on predictors of PEP after a naturalistic social performance situation. Sixty-five students, who had to give an evaluated presentation for credits, completed measures of trait social anxiety. Immediately after their presentation, participants rated state anxiety and attentional focus during the presentation, and provided an overall evaluation of their performance. One week after the presentation, they rated PEP during the preceding week, and reappraised their performance. Regression analyses demonstrated that the performance ratings after and self-focused attention during the presentation were unique predictors of PEP over and above the effects of trait and state anxiety. There was no evidence that PEP was associated with a biased recall of individual performance evaluations. The results support cognitive theories that emphasize the importance of negative self-perceptions in the development of social anxiety and related processes, and underline self-focused attention and self-evaluative processes as important targets during treatment.

Exploring Genetic Attributions Underlying Radiotherapy-Induced Fatigue in Prostate Cancer Patients.

Hashemi, Sepehr; Fernandez Martinez, Juan Luis; Saligan, Leorey; Sonis, Stephen

2017-09-01

Despite numerous proposed mechanisms, no definitive pathophysiology underlying radiotherapy-induced fatigue (RIF) has been established. However, the dysregulation of a set of 35 genes was recently validated to predict development of fatigue in prostate cancer patients receiving radiotherapy. To hypothesize novel pathways, and provide genetic targets for currently proposed pathways implicated in RIF development through analysis of the previously validated gene set. The gene set was analyzed for all phenotypic attributions implicated in the phenotype of fatigue. Initially, a "directed" approach was used by querying specific fatigue-related sub-phenotypes against all known phenotypic attributions of the gene set. Then, an "undirected" approach, reviewing the entirety of the literature referencing the 35 genes, was used to increase analysis sensitivity. The dysregulated genes attribute to neural, immunological, mitochondrial, muscular, and metabolic pathways. In addition, certain genes suggest phenotypes not previously emphasized in the context of RIF, such as ionizing radiation sensitivity, DNA damage, and altered DNA repair frequency. Several genes also associated with prostate cancer depression, possibly emphasizing variable radiosensitivity by RIF-prone patients, which may have palliative care implications. Despite the relevant findings, many of the 35 RIF-predictive genes are poorly characterized, warranting their investigation. The implications of herein presented RIF pathways are purely theoretical until specific end-point driven experiments are conducted in more congruent contexts. Nevertheless, the presented attributions are informative, directing future investigation to definitively elucidate RIF's pathoetiology. This study demonstrates an arguably comprehensive method of approaching known differential expression underlying a complex phenotype, to correlate feasible pathophysiology.

The combination of loss of habitat, human population encroachment, and increased demand of select nonhuman primates for biomedical research has significantly affected populations. There remains a need for knowledge and expertise in understanding background findings as related to the age, source, strain, and disease status of nonhuman primates. In particular, for safety/biomedical studies, a broader understanding and documentation of lesions would help clarify background from drug-related findings. A workshop and a minisymposium on spontaneous lesions and diseases in nonhuman primates were sponsored by the concurrent Annual Meetings of the American College of Veterinary Pathologists and the American Society for Veterinary Clinical Pathology held December 3-4, 2011, in Nashville, Tennessee. The first session had presentations from Drs Lowenstine and Montali, pathologists with extensive experience in wild and zoo populations of nonhuman primates, which was followed by presentations of 20 unique case reports of rare or newly observed spontaneous lesions in nonhuman primates (see online files for access to digital whole-slide images corresponding to each case report at http://www.scanscope.com/ACVP%20Slide%20Seminars/2011/Primate%20Pathology/view.apml). The minisymposium was composed of 5 nonhuman-primate researchers (Drs Bradley, Cline, Sasseville, Miller, Hutto) who concentrated on background and spontaneous lesions in nonhuman primates used in drug safety studies. Cynomolgus and rhesus macaques were emphasized, with some material presented on common marmosets. Congenital, acquired, inflammatory, and neoplastic changes were highlighed with a focus on clinical, macroscopic, and histopathologic findings that could confound the interpretation of drug safety studies.

When both narrow maxilla and moderately enlarged tonsils are present in children with obstructive sleep apnea, the decision of which treatment to do first is unclear. A preliminary randomized study was done to perform a power analysis and determine the number of subjects necessary to have an appropriate response. Thirty-one children, 14 boys, diagnosed with OSA based on clinical symptoms and polysomnography (PSG) findings had presence of both narrow maxillary complex and enlarged tonsils. They were scheduled to have both adeno-tonsillectomy and RME for which the order of treatment was randomized: group 1 received surgery followed by orthodontics, while group 2 received orthodontics followed by surgery. Each child was seen by an ENT, an orthodontist, and a sleep medicine specialist. The validated pediatric sleep questionnaire and PSG were done at entry and after each treatment phase at time of PSG. Statistical analyses were ANOVA repeated measures and t tests. The mean age of the children at entry was 6.5 ± 0.2 years (mean ± SEM). Overall, even if children presented improvement of both clinical symptoms and PSG findings, none of the children presented normal results after treatment 1, at the exception of one case. There was no significant difference in the amount of improvement noted independently of the first treatment approach. Thirty children underwent treatment 2, with an overall significant improvement shown for PSG findings compared to baseline and compared to treatment 1, without any group differences. This preliminary study emphasizes the need to have more than subjective clinical scales for determination of sequence of treatments.

The present work is aimed at finding variants associated with Type 1 and Type 2 diabetes mellitus (DM) that reside in functionally validated miRNAs binding sites and that can have a functional role in determining diabetes and related pathologies. Using bioinformatics analyses we obtained a database of validated polymorphic miRNA binding sites which has been intersected with genes related to DM or to variants associated and/or in linkage disequilibrium (LD) with it and is reported in genome-wide association studies (GWAS). The workflow we followed allowed us to find variants associated with DM that also reside in functional miRNA binding sites. These data have been demonstrated to have a functional role by impairing the functions of genes implicated in biological processes linked to DM. In conclusion, our work emphasized the importance of SNPs located in miRNA binding sites. The results discussed in this work may constitute the basis of further works aimed at finding functional candidates and variants affecting protein structure and function, transcription factor binding sites, and non-coding epigenetic variants, contributing to widen the knowledge about the pathogenesis of this important disease.

The authors of national guidelines emphasize the use of history and examination findings to diagnose community-acquired pneumonia (CAP) in outpatient children. Little is known about the interrater reliability of the physical examination in children with suspected CAP. This was a prospective cohort study of children with suspected CAP presenting to a pediatric emergency department from July 2013 to May 2016. Children aged 3 months to 18 years with lower respiratory signs or symptoms who received a chest radiograph were included. We excluded children hospitalized ≤14 days before the study visit and those with a chronic medical condition or aspiration. Two clinicians performed independent examinations and completed identical forms reporting examination findings. Interrater reliability for each finding was reported by using Fleiss' kappa (κ) for categorical variables and intraclass correlation coefficient (ICC) for continuous variables. No examination finding had substantial agreement (κ/ICC > 0.8). Two findings (retractions, wheezing) had moderate to substantial agreement (κ/ICC = 0.6-0.8). Nine findings (abdominal pain, pleuritic pain, nasal flaring, skin color, overall impression, cool extremities, tachypnea, respiratory rate, and crackles/rales) had fair to moderate agreement (κ/ICC = 0.4-0.6). Eight findings (capillary refill time, cough, rhonchi, head bobbing, behavior, grunting, general appearance, and decreased breath sounds) had poor to fair reliability (κ/ICC = 0-0.4). Only 3 examination findings had acceptable agreement, with the lower 95% confidence limit >0.4: wheezing, retractions, and respiratory rate. In this study, we found fair to moderate reliability of many findings used to diagnose CAP. Only 3 findings had acceptable levels of reliability. These findings must be considered in the clinical management and research of pediatric CAP. Copyright © 2017 by the American Academy of Pediatrics.

Implementation of a publication strategy in the context of reporting biases. A case study based on new documents from Neurontin® litigation

PubMed Central

2012-01-01

Background Previous studies have documented strategies to promote off-label use of drugs using journal publications and other means. Few studies have presented internal company communications that discussed financial reasons for manipulating the scholarly record related to off-label indications. The objective of this study was to build on previous studies to illustrate implementation of a publication strategy by the drug manufacturer for four off-label uses of gabapentin (Neurontin®, Pfizer, Inc.): migraine prophylaxis, treatment of bipolar disorders, neuropathic pain, and nociceptive pain. Methods We included in this study internal company documents, email correspondence, memoranda, study protocols and reports that were made publicly available in 2008 as part of litigation brought by consumers and health insurers against Pfizer for fraudulent sales practices in its marketing of gabapentin (see http://pacer.mad.uscourts.gov/dc/cgi-bin/recentops.pl?filename=saris/pdf/ucl%20opinion.pdf for the Court’s findings). We reviewed documents pertaining to 20 clinical trials, 12 of which were published. We categorized our observations related to reporting biases and linked them with topics covered in internal documents, that is, deciding what should and should not be published and how to spin the study findings (re-framing study results to explain away unfavorable findings or to emphasize favorable findings); and where and when findings should be published and by whom. Results We present extracts from internal company marketing assessments recommending that Pfizer and Parke-Davis (Pfizer acquired Parke-Davis in 2000) adopt a publication strategy to conduct trials and disseminate trial findings for unapproved uses rather than an indication strategy to obtain regulatory approval. We show internal company email correspondence and documents revealing how publication content was influenced and spin was applied; how the company selected where trial findings would be presented or published; how publication of study results was delayed; and the role of ghost authorship. Conclusions Taken together, the extracts we present from internal company documents illustrate implementation of a strategy at odds with unbiased study conduct and dissemination. Our findings suggest that Pfizer and Parke-Davis’s publication strategy had the potential to distort the scientific literature, and thus misinform healthcare decision-makers. PMID:22888801

Approximate computing trades off computation quality with the effort expended and as rising performance demands confront with plateauing resource budgets, approximate computing has become, not merely attractive, but even imperative. Here, we present a survey of techniques for approximate computing (AC). We discuss strategies for finding approximable program portions and monitoring output quality, techniques for using AC in different processing units (e.g., CPU, GPU and FPGA), processor components, memory technologies etc., and programming frameworks for AC. Moreover, we classify these techniques based on several key characteristics to emphasize their similarities and differences. Finally, the aim of this paper is tomore » provide insights to researchers into working of AC techniques and inspire more efforts in this area to make AC the mainstream computing approach in future systems.« less

Modeling human craniofacial disorders in Xenopus

Dubey, Aditi; Saint-Jeannet, Jean-Pierre

2017-01-01

Purpose of Review Craniofacial disorders are among the most common human birth defects and present an enormous health care and social burden. The development of animal models has been instrumental to investigate fundamental questions in craniofacial biology and this knowledge is critical to understand the etiology and pathogenesis of these disorders. Recent findings The vast majority of craniofacial disorders arise from abnormal development of the neural crest, a multipotent and migratory cell population. Therefore, defining the pathogenesis of these conditions starts with a deep understanding of the mechanisms that preside over neural crest formation and its role in craniofacial development. Summary This review discusses several studies using Xenopus embryos to model human craniofacial conditions, and emphasizes the strength of this system to inform important biological processes as they relate to human craniofacial development and disease.

Interfacing rare-earth-doped crystals with superconducting circuit architectures provides an attractive platform for quantum memory and transducer devices. Here, we present the detailed characterization of such a hybrid system: a locally implanted rare-earth Gd3 + in Al2O3 spin system coupled to a superconducting microresonator. We investigate the properties of the implanted spin system through angular-dependent microresonator electron spin resonance (micro-ESR) spectroscopy. We find, despite the high-energy near-surface implantation, the resulting micro-ESR spectra to be in excellent agreement with the modeled Hamiltonian, supporting the integration of dopant ions into their relevant lattice sites while maintaining crystalline symmetries. Furthermore, we observe clear contributions from individual microwave field components of our microresonator, emphasizing the need for controllable local implantation.

[The language disorders in schizophrenia in neurolinguistic and psycholinguistic perspectives].

PubMed

Piovan, Cristiano

2012-01-01

The descriptive psychopathology has classically equated the language with the formal aspects of thought. Recent developments in experimental and clinical research have emphasized the study of the language as a specific communicative ability. Within the framework of cognitive neuropsychology, the development of innovative research models, such as those based on the mentalizing ability, has allowed to formulate new hypotheses on the pathogenetic aspects of schizophrenia. Furthermore, mentalizing ability appears to be a basic skill for the pragmatic dimension of language. The author, after a brief description of the methods of investigation of neurolinguistics and psycholinguistics, presents a review of recent studies obtained by consulting the PubMed and PsycINFO databases. Finally, he focuses on the relationship between research findings and issues related to clinical practice.

More, M.

2018-02-01

We bring out an experience of organizing mathematical competitions that can be used as a medium to motivate the student and teacher minds in new directions of thinking. This can contribute to fostering research, innovation and provide a hands-on experience of mathematical concepts with the real world. Mathematical competitions can be used to build curiosity and give an understanding of mathematical applications in real life. Participation in the competition has been classified under four broad categories. Student can showcase their findings in various forms of expression like model, poster, soft presentation, animation, live performance, art and poetry. The basic focus of the competition is on using open source computation tools and modern technology, to emphasize the relationship of mathematical concepts with engineering applications in real life.

We re-present and re-examine the analysis from the famous RAND Health Insurance Experiment from the 1970s on the impact of consumer cost sharing in health insurance on medical spending. We begin by summarizing the experiment and its core findings in a manner that would be standard in the current age. We then examine potential threats to the validity of a causal interpretation of the experimental treatment effects stemming from different study participation and differential reporting of outcomes across treatment arms. Finally, we re-consider the famous RAND estimate that the elasticity of medical spending with respect to its out-of-pocket price is −0.2, emphasizing the challenges associated with summarizing the experimental treatment effects from non-linear health insurance contracts using a single price elasticity.

A true adult spinal lipoma is an exceedingly rare cause of lumbar compression neuropathy. Only 5 cases of true extradural intraforaminal lipomas have been documented in the medical literature. The diagnostic criteria and treatment guidelines for this specific lipoma have yet to be established. This report features 3 histologically confirmed cases of extradural intraforaminal spinal lipomas that recently presented to the authors' practice. In addition, the literature was surveyed to include the 5 previously reported cases of true adult extradural intraforaminal spinal lipomas. The consistency in presentation, response to surgical intervention, and postoperative recovery in these 8 cases supports surgical intervention at the time of diagnosis. The authors' findings support elevated clinical suspicion, efficient diagnosis based on MRI, and early surgical intervention for this rare pathological entity. All cases presented in this report were symptomatic and occurred in the absence of other significant pathologies such as general spinal epidural lipomatosis, intradural lesions, tethering, or severe degenerative stenosis or herniated discs. The clinical, neuroradiological, and histological findings characteristic of a true adult extradural intraforaminal lipoma are emphasized to differentiate this lesion from the more common etiologies for lumbar compression neuropathy. Heightened awareness and clinical suspicion for the focal, foraminal spinal lipoma as a cause of radiculopathy symptoms will enable more efficient diagnosis and treatment.

The growing street food sector in low-income countries offers easy access to inexpensive food as well as new job opportunities for urban residents. While this development is positive in many ways, it also presents new public health challenges for the urban population. Safe food hygiene is difficult to practice at street level, and outbreaks of diarrheal diseases have been linked to street food. This study investigates local perceptions of food safety among street food vendors and their consumers in Kumasi, Ghana in order to identify the most important aspects to be included in future public health interventions concerning street food safety. This qualitative study includes data from a triangulation of various qualitative methods. Observations at several markets and street food vending sites in Kumasi were performed. Fourteen street food vendors were chosen for in-depth studies, and extensive participant observations and several interviews were carried out with case vendors. In addition, street interviews and Focus Group Discussions were carried out with street food customers. The study found that although vendors and consumers demonstrated basic knowledge of food safety, the criteria did not emphasize basic hygiene practices such as hand washing, cleaning of utensils, washing of raw vegetables, and quality of ingredients. Instead, four main food selection criteria could be identified and were related to (1) aesthetic appearance of food and food stand, (2) appearance of the food vendor, (3) interpersonal trust in the vendor, and (4) consumers often chose to prioritize price and accessibility of food--not putting much stress on food safety. Hence, consumers relied on risk avoidance strategies by assessing neatness, appearance, and trustworthiness of vendor. Vendors were also found to emphasize appearance while vending and to ignore core food safety practices while preparing food. These findings are discussed in this paper using social and anthropological theoretical concepts such as 'purity', 'contamination', 'hygiene puzzles', and 'impression behaviors' from Douglas, Van Der Geest, and Goffman. The findings indicate that educating vendors in safe food handling is evidently insufficient. Future public health interventions within the street food sector should give emphasis to the importance of appearance and neatness when designing communication strategies. Neglected aspects of food safety, such as good hand hygiene and cleanliness of kitchen facilities, should be emphasized. Local vendor networks can be an effective point of entry for future food hygiene promotion initiatives.

What makes African American health disparities newsworthy? An experiment among journalists about story framing.

Hinnant, Amanda; Oh, Hyun Jee; Caburnay, Charlene A; Kreuter, Matthew W

News stories reporting race-specific health information commonly emphasize disparities between racial groups. But recent research suggests this focus on disparities has unintended effects on African American audiences, generating negative emotions and less interest in preventive behaviors (Nicholson RA, Kreuter MW, Lapka C et al. Unintended effects of emphasizing disparities in cancer communication to African-Americans. Cancer Epidemiol Biomarkers Prev 2008; 17: 2946-52). They found that black adults are more interested in cancer screening after reading about the progress African Americans have made in fighting cancer than after reading stories emphasizing disparities between blacks and whites. This study builds on past findings by (i) examining how health journalists judge the newsworthiness of stories that report race-specific health information by emphasizing disparities versus progress and (ii) determining whether these judgments can be changed by informing journalists of audience reactions to disparity versus progress framing. In a double-blind-randomized experiment, 175 health journalists read either a disparity- or progress-framed story on colon cancer, preceded by either an inoculation about audience effects of such framing or an unrelated (i.e. control) information stimuli. Journalists rated the disparity-frame story more favorably than the progress-frame story in every category of news values. However, the inoculation significantly increased positive reactions to the progress-frame story. Informing journalists of audience reactions to race-specific health information could influence how health news stories are framed.

Experimental studies of characteristic combustion-driven flows for CFD validation

NASA Technical Reports Server (NTRS)

Santoro, R. J.; Moser, M.; Anderson, W.; Pal, S.; Ryan, H.; Merkle, C. L.

1992-01-01

A series of rocket-related studies intended to develop a suitable data base for validation of Computational Fluid Dynamics (CFD) models of characteristic combustion-driven flows was undertaken at the Propulsion Engineering Research Center at Penn State. Included are studies of coaxial and impinging jet injectors as well as chamber wall heat transfer effects. The objective of these studies is to provide fundamental understanding and benchmark quality data for phenomena important to rocket combustion under well-characterized conditions. Diagnostic techniques utilized in these studies emphasize determinations of velocity, temperature, spray and droplet characteristics, and combustion zone distribution. Since laser diagnostic approaches are favored, the development of an optically accessible rocket chamber has been a high priority in the initial phase of the project. During the design phase for this chamber, the advice and input of the CFD modeling community were actively sought through presentations and written surveys. Based on this procedure, a suitable uni-element rocket chamber was fabricated and is presently under preliminary testing. Results of these tests, as well as the survey findings leading to the chamber design, were presented.

Interactions between space-based and feature-based attention.

PubMed

Leonard, Carly J; Balestreri, Angela; Luck, Steven J

2015-02-01

Although early research suggested that attention to nonspatial features (i.e., red) was confined to stimuli appearing at an attended spatial location, more recent research has emphasized the global nature of feature-based attention. For example, a distractor sharing a target feature may capture attention even if it occurs at a task-irrelevant location. Such findings have been used to argue that feature-based attention operates independently of spatial attention. However, feature-based attention may nonetheless interact with spatial attention, yielding larger feature-based effects at attended locations than at unattended locations. The present study tested this possibility. In 2 experiments, participants viewed a rapid serial visual presentation (RSVP) stream and identified a target letter defined by its color. Target-colored distractors were presented at various task-irrelevant locations during the RSVP stream. We found that feature-driven attentional capture effects were largest when the target-colored distractor was closer to the attended location. These results demonstrate that spatial attention modulates the strength of feature-based attention capture, calling into question the prior evidence that feature-based attention operates in a global manner that is independent of spatial attention.

The development of pointing perception in infancy: effects of communicative signals on covert shifts of attention.

PubMed

Daum, Moritz M; Ulber, Julia; Gredebäck, Gustaf

2013-10-01

The present study aims to investigate the interplay of verbal and nonverbal communication with respect to infants' perception of pointing gestures. Infants were presented with still images of pointing hands (cue) in combination with an acoustic stimulus. The communicative content of this acoustic stimulus was varied from being human and communicative to artificial. Saccadic reaction times (SRTs) from the cue to a peripheral target were measured as an indicator of the modulation of covert attention. A significant cueing effect (facilitated SRTs for congruent compared with incongruent trials) was only present in a condition with additional communicative and referential speech. In addition, the size of the cueing effect increased the more human and communicative the acoustic stimulus was. This indicates a beneficial effect of verbal communication on the perception of nonverbal communicative pointing gestures, emphasizing the important role of verbal communication in facilitating social understanding across domains. These findings additionally suggest that human and communicative (ostensive) signals are not qualitatively different from other less social signals but just quantitatively the most attention grabbing among a number of other signals.

The mental health liaison nurse role in the emergency department (ED) has demonstrated a range of positive outcomes for both consumers and staff. In Australia, the added value associated with establishing mental health nurse practitioner (MHNP) positions based on this model is emerging. This paper presents qualitative findings from a study using a mixed-method design to evaluate an ED-based MHNP outpatient service in Sydney, Australia. In evaluating this new service, semistructured interviews were conducted with a random selection of study participants and a stratified sample of ED staff. This is the first of a two-part paper that presents an analysis of qualitative data from interviews conducted with study participants (n = 23). Participants reported numerous therapeutic benefits from the service, such as support, understanding, and a focus on solutions rather than problems, and high levels of satisfaction with the accessibility of the service and follow up. Suggestions for improving the service were also offered. Participants emphasized that overall ED service provision would be enhanced through additional resources, especially an extension of operating hours. Findings from these participant interviews provide strong support for an ED-based MHNP outpatient service. © 2011 The Authors.

Simple pebble tools, ephemeral cultural features, and the remains of maritime and terrestrial foods are present in undisturbed Late Pleistocene and Early Holocene deposits underneath a large human-made mound at Huaca Prieta and nearby sites on the Pacific coast of northern Peru. Radiocarbon ages indicate an intermittent human presence dated between ~15,000 and 8000 calendar years ago before the mound was built. The absence of fishhooks, harpoons, and bifacial stone tools suggests that technologies of gathering, trapping, clubbing, and exchange were used primarily to procure food resources along the shoreline and in estuarine wetlands and distant mountains. The stone artifacts are minimally worked unifacial stone tools characteristic of several areas of South America. Remains of avocado, bean, and possibly cultivated squash and chile pepper are also present, suggesting human transport and consumption. Our new findings emphasize an early coastal lifeway of diverse food procurement strategies that suggest detailed observation of resource availability in multiple environments and a knowledgeable economic organization, although technologies were simple and campsites were seemingly ephemeral and discontinuous. These findings raise questions about the pace of early human movement along some areas of the Pacific coast and the level of knowledge and technology required to exploit maritime and inland resources.

Runtime Detection of C-Style Errors in UPC Code

2011-09-29

Unified Parallel C (UPC) extends the C programming language (ISO C 99) with explicit parallel programming support for the partitioned global address space (PGAS), which provides a global memory space with localized partitions to each thread. Like its ancestor C, UPC is a low-level language that emphasizes code efficiency over safety. The absence of dynamic (and static) safety checks allows programmer oversights and software flaws that can be hard to spot. In this paper, we present an extension of a dynamic analysis tool, ROSE-Code Instrumentation and Runtime Monitor (ROSECIRM), for UPC to help programmers find C-style errors involving the globalmore » address space. Built on top of the ROSE source-to-source compiler infrastructure, the tool instruments source files with code that monitors operations and keeps track of changes to the system state. The resulting code is linked to a runtime monitor that observes the program execution and finds software defects. We describe the extensions to ROSE-CIRM that were necessary to support UPC. We discuss complications that arise from parallel code and our solutions. We test ROSE-CIRM against a runtime error detection test suite, and present performance results obtained from running error-free codes. ROSE-CIRM is released as part of the ROSE compiler under a BSD-style open source license.« less

Students as researchers: What and why seventh‐grade students choose to write when investigating their own research question

Abstract All scientists depend on both reading and writing to do their scientific work. It is of paramount importance to ensure that students have a relevant repertoire of practices they can employ when facing scientific content inside and outside the school context. The present study reports on students in seventh grade acting as researchers. Over an 8‐week collaborative research period, students posed their own research question, attempted to answer it by systematically testing hypotheses, discussing findings, presenting their conclusions, and documenting their process in a written report. Drawing on the perspectives of New Literacy Studies—which sees literacy as socially situated—we analyze the purpose of all the 21 participating students’ texts (n = 344). Video observations and interviews with students are used to contextualize the writing events. We find that the students chose to write multiple kinds of texts for a variety of purposes. Analyzing purpose and the context, three stages of socialization into scientific writing is revealed, ranging from what the students write on their own initiative, via texts written through challenges to demanding research tasks scaffolded through writing instructions given by the teacher. Further, the students emphasized the relevance of both the research experience and the writing to their future adult life. PMID:29540938

PDT-based combinations in overcoming chemoresistance from stromal and heterotypic cellular communication (Conference Presentation)

Targeting the molecular and cellular cues that influence treatment resistance in tumors is critical to effectively treating unresponsive populations of stubborn disease. The informed design of mechanism-based combinations is emerging as increasingly important to targeting resistance and improving the efficacy of conventional treatments, while minimizing toxicity. Photodynamic therapy (PDT) has been shown to synergize with conventional agents and to overcome the evasion pathways that cause resistance. Increasing evidence shows that PDT-based combinations cooperate mechanistically with, and improve the therapeutic index of, traditional chemotherapies. These and other findings emphasize the importance of including PDT as part of comprehensive treatment plans for cancer, particularly in complex disease sites. Identifying effective combinations requires a multi-faceted approach that includes the development of bioengineered cancer models and corresponding image analysis tools. The molecular and phenotypic basis of verteporfin-mediated PDT-based enhancement of chemotherapeutic efficacy and predictability in complex 3D models for ovarian cancer will be presented.

An interesting case report of vertebral artery dissection following polytrauma.

The authors present an interesting case of a 19-year-old male who presented as a polytrauma patient following a fall from a height. He was initially managed on the intensive care unit with intracranial pressure bolt monitoring after being intubated and sedated and having his other traumatic injuries stabilized. Upon attempting to wean sedation and extubation a repeat CT scan of the head was undertaken and showed a new area suggested of cerebral infarction, this was a new finding. Further imaging found that he had a cervical vertebral artery dissection following this polytrauma mode of injury. The incidence of vertebral artery dissection following generalized or local trauma is rising but routine imaging/screening in these patients is not undertaken. Our report displays select images related to this case report and emphasizes the consideration of routine imaging in head and neck traumatic injuries to diagnose internal carotid and/or vertebral artery dissections much earlier.

2009-07-01

Communication involves a wide range of behaviours that animals emit in their daily lives and can take place between different species, as is the case of domestic dogs (Canis familiaris) and humans. Dogs have shown to be successful at following human cues to solve the object choice task. The question is what are the mechanisms involved in these communicative abilities. This article presents a review of studies about the communicative capacities of domestic dogs emphasizing the ones that considered the effect of associative learning upon these skills. In addition, evidence about differences in dogs' performance in following physical or social cues is summarized and two studies where both signals compete are presented here. The obtained results suggest that the training of a colour cue reverses the dogs' preference for the social one. These results are discussed in light of the findings that gave importance to the learning effect, concluding that the dogs fundamentally follow those cues that allowed them to obtain reinforcers in their previous learning history.

Toxocara malaysiensis infection in domestic cats in Vietnam--An emerging zoonotic issue?

Le, Thanh Hoa; Anh, Nguyen Thi Lan; Nguyen, Khue Thi; Nguyen, Nga Thi Bich; Thuy, Do Thi Thu; Gasser, Robin B

2016-01-01

Toxocara canis of canids is a parasitic nematode (ascaridoid) that infects humans and other hosts, causing different forms of toxocariasis. This species of Toxocara appears to be the most important cause of human disease, likely followed by Toxocara cati from felids. Although some studies from Malaysia and China have shown that cats can harbor another congener, T. malaysiensis, no information is available about this parasite for other countries. Moreover, the zoonotic potential of this parasite is unknown at this point. In the present study, we conducted the first investigation of domestic dogs and cats for Toxocara in Vietnam using molecular tools. Toxocara malaysiensis was identified as a common ascaridoid of domestic cats (in the absence of T. cati), and T. canis was commonly found in dogs. Together with findings from previous studies, the present results emphasize the need to explore the significance and zoonotic potential of T. malaysiensis in Vietnam and other countries where this parasite is endemic and prevalent in cats.

Terror management theory posits that people tend to respond defensively to reminders of death, including worldview defense, self-esteem striving, and suppression of death thoughts. Seven experiments examined whether trait mindfulness-a disposition characterized by receptive attention to present experience-reduced defensive responses to mortality salience (MS). Under MS, less mindful individuals showed higher worldview defense (Studies 1-3) and self-esteem striving (Study 5), yet more mindful individuals did not defend a constellation of values theoretically associated with mindfulness (Study 4). To explain these findings through proximal defense processes, Study 6 showed that more mindful individuals wrote about their death for a longer period of time, which partially mediated the inverse association between trait mindfulness and worldview defense. Study 7 demonstrated that trait mindfulness predicted less suppression of death thoughts immediately following MS. The discussion highlights the relevance of mindfulness to theories that emphasize the nature of conscious processing in understanding responses to threat.

Improving comprehension and recall of information for an HIV vaccine trial among women at risk for HIV: reading level simplification and inclusion of pictures to illustrate key concepts.

1999-10-01

A simplified version of the prototype HIV vaccine material was developed through (a) reducing reading grade level, (b) restructuring of the organization and categorization of the material, (c) adding pictures designed to emphasize key concepts, and (d) obtaining feedback on the simplified version through focus groups with the target population. Low-income women at risk for HIV (N = 141) recruited from a primary care clinic were randomly assigned to be presented the standard or the simplified version. There were no significant differences between the groups in terms of education or Vocabulary, Block Design, and Passage Comprehension scores. Women who received the simplified version had significantly higher comprehension scores immediately following presentation of the material than did women who received the standard version and were also significantly more likely to recall study benefits and risks. These findings were maintained at 3-month follow-up. Implications for informed consent are discussed.

We describe an eight-week summer Young Scientist in Training (YSIT) internship program involving middle and high school students. This program exposed students to current basic research in molecular genetics, while introducing or reinforcing principles of the scientific method and demonstrating the uses of mathematics and chemistry in biology. For the laboratory-based program, selected students from Baltimore City Schools working in groups of three were teamed with undergraduate research assistants at Morgan State University. Teams were assigned a project that was indirectly related to our laboratory research on the characterization of gene expression in Caenorhabditis elegans. At the end of the program, teams prepared posters detailing their accomplishments, and presented their findings to parents and faculty members during a mini-symposium. The posters were also submitted to the respective schools and the interns were offered a presentation of their research at local high school science fairs.

Reusable, extensible, and modifiable R scripts and Kepler workflows for comprehensive single set ChIP-seq analysis.

PubMed

Cormier, Nathan; Kolisnik, Tyler; Bieda, Mark

2016-07-05

There has been an enormous expansion of use of chromatin immunoprecipitation followed by sequencing (ChIP-seq) technologies. Analysis of large-scale ChIP-seq datasets involves a complex series of steps and production of several specialized graphical outputs. A number of systems have emphasized custom development of ChIP-seq pipelines. These systems are primarily based on custom programming of a single, complex pipeline or supply libraries of modules and do not produce the full range of outputs commonly produced for ChIP-seq datasets. It is desirable to have more comprehensive pipelines, in particular ones addressing common metadata tasks, such as pathway analysis, and pipelines producing standard complex graphical outputs. It is advantageous if these are highly modular systems, available as both turnkey pipelines and individual modules, that are easily comprehensible, modifiable and extensible to allow rapid alteration in response to new analysis developments in this growing area. Furthermore, it is advantageous if these pipelines allow data provenance tracking. We present a set of 20 ChIP-seq analysis software modules implemented in the Kepler workflow system; most (18/20) were also implemented as standalone, fully functional R scripts. The set consists of four full turnkey pipelines and 16 component modules. The turnkey pipelines in Kepler allow data provenance tracking. Implementation emphasized use of common R packages and widely-used external tools (e.g., MACS for peak finding), along with custom programming. This software presents comprehensive solutions and easily repurposed code blocks for ChIP-seq analysis and pipeline creation. Tasks include mapping raw reads, peakfinding via MACS, summary statistics, peak location statistics, summary plots centered on the transcription start site (TSS), gene ontology, pathway analysis, and de novo motif finding, among others. These pipelines range from those performing a single task to those performing full analyses of ChIP-seq data. The pipelines are supplied as both Kepler workflows, which allow data provenance tracking, and, in the majority of cases, as standalone R scripts. These pipelines are designed for ease of modification and repurposing.

Integrating molecular and morphological approaches for characterizing parasite cryptic species: implications for parasitology.

PubMed

Nadler, Steven A; DE León, Gerardo Pérez-Ponce

2011-11-01

Herein we review theoretical and methodological considerations important for finding and delimiting cryptic species of parasites (species that are difficult to recognize using traditional systematic methods). Applications of molecular data in empirical investigations of cryptic species are discussed from an historical perspective, and we evaluate advantages and disadvantages of approaches that have been used to date. Developments concerning the theory and practice of species delimitation are emphasized because theory is critical to interpretation of data. The advantages and disadvantages of different molecular methodologies, including the number and kind of loci, are discussed relative to tree-based approaches for detecting and delimiting cryptic species. We conclude by discussing some implications that cryptic species have for research programmes in parasitology, emphasizing that careful attention to the theory and operational practices involved in finding, delimiting, and describing new species (including cryptic species) is essential, not only for fully characterizing parasite biodiversity and broader aspects of comparative biology such as systematics, evolution, ecology and biogeography, but to applied research efforts that strive to improve development and understanding of epidemiology, diagnostics, control and potential eradication of parasitic diseases.

Even with nonnative interactions, the updated folding transition states of the homologs Proteins G & L are extensive and similar

Experimental and computational folding studies of Proteins L & G and NuG2 typically find that sequence differences determine which of the two hairpins is formed in the transition state ensemble (TSE). However, our recent work on Protein L finds that its TSE contains both hairpins, compelling a reassessment of the influence of sequence on the folding behavior of the other two homologs. We characterize the TSEs for Protein G and NuG2b, a triple mutant of NuG2, using ψ analysis, a method for identifying contacts in the TSE. All three homologs are found to share a common and near-native TSE topology with interactions between all four strands. However, the helical content varies in the TSE, being largely absent in Proteins G & L but partially present in NuG2b. The variability likely arises from competing propensities for the formation of nonnative β turns in the naturally occurring proteins, as observed in our TerItFix folding algorithm. All-atom folding simulations of NuG2b recapitulate the observed TSEs with four strands for 5 of 27 transition paths [Lindorff-Larsen K, Piana S, Dror RO, Shaw DE (2011) Science 334(6055):517–520]. Our data support the view that homologous proteins have similar folding mechanisms, even when nonnative interactions are present in the transition state. These findings emphasize the ongoing challenge of accurately characterizing and predicting TSEs, even for relatively simple proteins. PMID:26100906

The "Finding Physics" Project: Recognizing and Exploring Physics Outside the Classroom

NASA Astrophysics Data System (ADS)

Beck, Judith; Perkins, James

2016-11-01

Students in introductory physics classes often have difficulty recognizing the relevance of physics concepts outside the confines of the physics classroom, lab, and textbook. Even though textbooks and instructors often provide examples of physics applications from a wide array of areas, students have difficulty relating physics to their own lives. Encouraging students to apply physics to their own surroundings helps them develop the critical analysis skills of a scientifically literate and competent citizen. Fink, in his book Creating Significant Learning Experiences, emphasizes the importance of constructing opportunities to help students connect what they learn in their academic courses with past and current life experiences and link them to possible future life experiences. Several excellent papers in this journal have presented labs and activities that address this concern by encouraging teachers to bring real-world examples into the classroom or to take students into the field for data collection and observation. Alternatively, Smith suggests a writing exercise in which his students identify and explain an event in terms of their understanding of physics. In this paper we present a multiphase exercise that challenges students to find their own examples of physics from outside the classroom and analyze them using the conceptual understanding and quantitative skills which they are developing in the classroom. The ultimate goal of the "Finding Physics" project is to improve students' learning through enhancing their recognition that, to quote one participant's end-of-course survey, "Physics is everywhere!"

The analysis aimed to identify the treatment gaps in current fracture liaison services (FLS) and to provide recommendations for best practice establishment of future FLS across the Asia-Pacific region. The findings emphasize the unmet need for the implementation of new programs and provide recommendations for the refinement of existing ones. The study's objectives were to evaluate fracture liaison service (FLS) programs in the Asia-Pacific region and provide recommendations for establishment of future FLS programs. A systematic literature review (SLR) of Medline, PubMed, EMBASE, and Cochrane Library (2000-2017 inclusive) was performed using the following keywords: osteoporosis, fractures, liaison, and service. Inclusion criteria included the following: patients ≥ 50 years with osteoporosis-related fractures; randomized controlled trials or observational studies with control groups (prospective or retrospective), pre-post, cross-sectional and economic evaluation studies. Success of direct or indirect interventions was assessed based on patients' understanding of risk, bone mineral density assessment, calcium intake, osteoporosis treatment, re-fracture rates, adherence, and mortality, in addition to cost-effectiveness. Overall, 5663 unique citations were identified and the SLR identified 159 publications, reporting 37 studies in Asia-Pacific. These studies revealed the unmet need for public health education, adequate funding, and staff resourcing, along with greater cooperation between departments and physicians. These actions can help to overcome therapeutic inertia with sufficient follow-up to ensure adherence to recommendations and compliance with treatment. The findings also emphasize the importance of primary care physicians continuing to prescribe treatment and ensure service remains convenient. These findings highlight the limited evidence supporting FLS across the Asia-Pacific region, emphasizing the unmet need for new programs and/or refinement of existing ones to improve outcomes. With the continued increase in burden of fractures in Asia-Pacific, establishment of new FLS and assessment of existing services are warranted to determine the impact of FLS for healthcare professionals, patients, family/caregivers, and society.

2016-09-01

Excessive post-mortem processing after social situations, a core symptom of social anxiety disorder (SAD), is thought to contribute to the perpetuation of social anxiety by consolidating negative self-schemata. Empirical findings on actual mechanisms underlying this so-called Post-Event Processing (PEP) are still scarce. The present study sought to identify variables associated with the experience of PEP after real-life social situations in a sample of 49 individuals diagnosed with SAD. Using an ambulatory assessment approach, individuals were asked to report on each distressing social event experienced during one week. A total of 192 events were captured. Hierarchical linear modeling indicated that next to trait social anxiety, the type of social situation (performance vs. interaction situations), self-focused attention, safety behavior use, and negative affect predicted levels of PEP after social situations. These findings add to the growing literature that emphasizes the importance of situational factors for the experience of PEP, and highlight potential venues to prevent it.

Australia’s first national level quantitative environmental justice assessment of industrial air pollution

NASA Astrophysics Data System (ADS)

Chakraborty, Jayajit; Green, Donna

2014-04-01

This study presents the first national level quantitative environmental justice assessment of industrial air pollution in Australia. Specifically, our analysis links the spatial distribution of sites and emissions associated with industrial pollution sources derived from the National Pollution Inventory, to Indigenous status and social disadvantage characteristics of communities derived from Australian Bureau of Statistics indicators. Our results reveal a clear national pattern of environmental injustice based on the locations of industrial pollution sources, as well as volume, and toxicity of air pollution released at these locations. Communities with the highest number of polluting sites, emission volume, and toxicity-weighted air emissions indicate significantly greater proportions of Indigenous population and higher levels of socio-economic disadvantage. The quantities and toxicities of industrial air pollution are particularly higher in communities with the lowest levels of educational attainment and occupational status. These findings emphasize the need for more detailed analysis in specific regions and communities where socially disadvantaged groups are disproportionately impacted by industrial air pollution. Our empirical findings also underscore the growing necessity to incorporate environmental justice considerations in environmental planning and policy-making in Australia.

Ameliorating effects of preadolescent aniracetam treatment on prenatal ethanol-induced impairment in AMPA receptor activity.

Ethanol-induced damage in the developing hippocampus may result in cognitive deficits such as those observed in fetal alcohol spectrum disorder (FASD). Cognitive deficits in FASD are partially mediated by alterations in glutamatergic synaptic transmission. Recently, we reported that synaptic transmission mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) is impaired following fetal ethanol exposure. This finding led us to develop a rational approach for the treatment of alcohol-related cognitive deficits using aniracetam, an allosteric AMPAR modulator. In the present study, 28 to 34-day-old rats exposed to ethanol in utero were treated with aniracetam, and subsequently exhibited persistent improvement in mEPSC amplitude, frequency, and decay time. Furthermore, these animals expressed positive changes in synaptic single channel properties, suggesting that aniracetam ameliorates prenatal ethanol-induced deficits through modifications at the single channel level. Specifically, single channel open probability, conductance, mean open and closed times, and the number and burst duration were positively affected. Our findings emphasize the utility of compounds which slow the rate of deactivation and desensitization of AMPARs such as aniracetam.

Lessons from Practice: Designing Tools to Facilitate Individualized Support for Quitting Smoking

PubMed Central

Bhattacharya, Arpita; Vilardaga, Roger; Kientz, Julie A.; Munson, Sean A.

2017-01-01

Many health care providers, with a variety of trainings, counsel clients on quitting smoking on a day-to-day basis. In their clinical practice, they draw from and adapt guidelines and research-based strategies to fit individual client situations and challenges. Designers of technologies to support quitting smoking can learn from these real world practices to create tools that better adapt to individual differences. We present findings from interviews with 28 providers with diverse experiences in smoking cessation counselling. Through analysis of their individualization strategies, challenges, and perceptions of technology, we find that providers: (1) individualize context appropriate coping strategies by involving clients in brainstorming, (2) emphasize the need to support nicotine withdrawal in clients, (3) mitigate social triggers and mediate social support for clients, and (4) need to navigate dependencies with other providers for managing medications and comorbid health conditions of clients. With this empirical understanding, we extend the discussion on the design of technology to support quitting smoking, highlight current barriers to individualization, and suggest future opportunities to address these barriers.

The multidimensional nature of ageism: construct validity and group differences.

PubMed

Rupp, Deborah E; Vodanovich, Stephen J; Credé, Marcus

2005-06-01

The authors investigated the factor structure and construct validity of the Fraboni Scale of Ageism and the age and gender differences in ageism scores. Confirmatory factor analyses supported the multidimensional nature of FSA scores and generally corroborated the initial factor structure reported by M. Fraboni, with some notable exceptions. Essentially, the present findings were aligned with theoretical models of ageism that emphasize both cognitive facets and affective facets. That is, on the basis of their factor analytic findings, the authors redefined Fraboni's original factors of Antilocution, Avoidance, and Discrimination as Stereotypes, Separation, and Affective Attitudes, respectively, because of the clustering of items within factors. The revised 3-factor structure accounted for 36.4% of the variance in FSA scores. FSA factor scores significantly related to other scores from other measures of age-related attitudes, with higher correlations among factors that were similar in terms of their cognitive nature versus their affective nature. Finally, younger individuals and men had significantly higher ageism scores on the FSA than older individuals and women. The authors discussed the importance of adequately assessing ageism, with particular emphasis devoted to the understanding of age bias.

Symptom dimensions in obsessive-compulsive disorder: phenomenology and treatment outcomes with exposure and ritual prevention.

PubMed

Williams, Monnica T; Mugno, Beth; Franklin, Martin; Faber, Sonya

2013-01-01

Obsessive-compulsive disorder (OCD) is a severe condition with varied symptom presentations. Currently, the cognitive-behavioral treatment with the most empirical support is exposure and ritual prevention (EX/RP); however, clinical impression and some empirical data suggest that certain OCD symptoms are more responsive to treatment than others. Prior work identifying symptom dimensions within OCD is discussed, including epidemiological findings, factor analytic studies, and biological findings. Symptom dimensions most reliably identified include contamination/cleaning, doubt about harm/checking, symmetry/ordering, and unacceptable thoughts/mental rituals. The phenomenology of each of these subtypes is described and research literature is summarized, emphasizing the differential effects of EX/RP and its variants on each of these primary symptom dimensions. To date it appears that EX/RP is an effective treatment for the various OCD dimensions, although not all dimensions have been adequately studied (i.e. symmetry and ordering). Modifications to treatment may be warranted for some types of symptoms. Clinical implications and directions for future research are discussed. Copyright © 2013 S. Karger AG, Basel.

Conditioning attentional skills: examining the effects of the pace of television editing on children's attention.

PubMed

Cooper, N R; Uller, C; Pettifer, J; Stolc, F C

2009-10-01

There is increasing concern about the behavioural and cognitive effects of watching television in childhood. Numerous studies have examined the effects of the amount of viewing time; however, to our knowledge, only one study has investigated whether the speed of editing of a programme may have an effect on behaviour. The purpose of the present study was to examine this question using a novel experimental paradigm. School children (aged 4-7 years) were randomly assigned to one of two groups. Each group was presented with either a fast- or slow-edit 3.5-min film of a narrator reading a children's story. Immediately following film presentation, both groups were presented with a continuous test of attention. Performance varied according to experimental group and age. In particular, we found that children's orienting networks and error rates can be affected by a very short exposure to television. Just 3.5 min of watching television can have a differential effect on the viewer depending on the pacing of the film editing. These findings highlight the potential of experimentally manipulating television exposure in children and emphasize the need for more research in this previously under-explored topic.

Adoption of electronic health record systems has increased the availability of patient-level electronic health information. To examine public support for secondary uses of electronic health information under different consent arrangements. National experimental survey to examine perceptions of uses of electronic health information according to patient consent (obtained vs. not obtained), use (research vs. marketing), and framing of the findings (abstract description without results vs. specific results). Nationally representative survey. 3064 African American, Hispanic, and non-Hispanic white persons (response rate, 65%). Appropriateness of health information use described in vignettes on a scale of 1 (not at all appropriate) to 10 (very appropriate). Mean ratings ranged from a low of 3.81 for a marketing use when consent was not obtained and specific results were presented to a high of 7.06 for a research use when consent was obtained and specific results were presented. Participants rated scenarios in which consent was obtained as more appropriate than when consent was not obtained (difference, 1.01 [95% CI, 0.69 to 1.34]; P<0.001). Participants rated scenarios in which the use was marketing as less appropriate than when the use was research (difference, -2.03 [CI, -2.27 to -1.78]; P<0.001). Unconsented research uses were rated as more appropriate than consented marketing uses (5.65 vs. 4.52; difference, 1.13 [CI, 0.87 to 1.39]). Participants rated hypothetical scenarios. Results could be vulnerable to nonresponse bias despite the high response rate. Although approaches to health information sharing emphasize consent, public opinion also emphasizes purpose, which suggests a need to focus more attention on the social value of information use.

Facial ontogeny in Neanderthals and modern humans

PubMed Central

Bastir, Markus; O'Higgins, Paul; Rosas, Antonio

2007-01-01

One hundred and fifty years after the discovery of Neanderthals, it is held that this morphologically and genetically distinct human species does not differ from modern Homo sapiens in its craniofacial ontogenetic trajectory after the early post-natal period. This is striking given the evident morphological differences between these species, since it implies that all of the major differences are established by the early post-natal period and carried into adulthood through identical trajectories, despite the extent to which mechanical and spatial factors are thought to influence craniofacial ontogeny. Here, we present statistical and morphological analyses demonstrating that the spatio-temporal processes responsible for craniofacial ontogenetic transformations differ. The findings emphasize that pre-natal as well as post-natal ontogeny are both important in establishing the cranial morphological differences between adult Neanderthals and modern humans.

Formation of the Oort Cloud: Coupling Dynamical and Collisional Evolutions of Cometesimals

NASA Astrophysics Data System (ADS)

Charnoz, S.; Morbidelli, A.

2002-09-01

Cometesimals are thought to be born in the region of Giant Planets region and were subsequently ejected to the Oort Cloud by gravitational scattering. Some recent works (Stern & Weisman, 2001 Nature 409) have emphasized that during this phase of violent ejection, random velocities among cometesimals become so high that the majority of kilometer-sized comets might have been destroyed by multiple violent collisions before they reach the Oort Cloud, resulting in a low mass Oort Cloud. We present a new approach which allows to couple dynamical and collisional evolutions. This study focuses on cometesimals starting from the Jupiter-Saturn region. We find that the rapid depletion of the disk, due to the gravitational-scattering exerted by the giant planets, prevents a large fraction of cometesimals from rapid collisional destruction. These conclusions support the classical scenario of Oort Cloud formation.

Diversity and function of bacterial microbiota in the mosquito holobiont

PubMed Central

2013-01-01

Mosquitoes (Diptera: Culicidae) have been shown to host diverse bacterial communities that vary depending on the sex of the mosquito, the developmental stage, and ecological factors. Some studies have suggested a potential role of microbiota in the nutritional, developmental and reproductive biology of mosquitoes. Here, we present a review of the diversity and functions of mosquito-associated bacteria across multiple variation factors, emphasizing recent findings. Mosquito microbiota is considered in the context of possible extended phenotypes conferred on the insect hosts that allow niche diversification and rapid adaptive evolution in other insects. These kinds of observations have prompted the recent development of new mosquito control methods based on the use of symbiotically-modified mosquitoes to interfere with pathogen transmission or reduce the host life span and reproduction. New opportunities for exploiting bacterial function for vector control are highlighted. PMID:23688194

Individual psychotherapy for schizophrenia: trends and developments in the wake of the recovery movement.

PubMed

Hamm, Jay A; Hasson-Ohayon, Ilanit; Kukla, Marina; Lysaker, Paul H

2013-01-01

Although the role and relative prominence of psychotherapy in the treatment of schizophrenia has fluctuated over time, an analysis of the history of psychotherapy for schizophrenia, focusing on findings from the recovery movement, reveals recent trends including the emergence of the development of integrative psychotherapy approaches. The authors suggest that the recovery movement has revealed limitations in traditional approaches to psychotherapy, and has provided opportunities for integrative approaches to emerge as a mechanism for promoting recovery in persons with schizophrenia. Five approaches to integrative psychotherapy for persons with schizophrenia are presented, and a shared conceptual framework that allows these five approaches to be compatible with one another is proposed. The conceptual framework is consistent with theories of recovery and emphasizes interpersonal attachment, personal narrative, and metacognitive processes. Implications for future research on integrative psychotherapy are considered.

Replacing critical and strategic refractory metal elements in nickel-base superalloys. [NASA's COSAM program

Stephens, J. R.; Dreshfield, R. L.; Nathal, M. V.

1983-01-01

Because of the import status and essential nature of their use, cobalt, chromium, tantalum, and niobium were identified as strategic and critical in the aerospace industry. NASA's Conservation of Strategic Aerospace Materials (COSAM) program aims to reduce the need for strategic materials used in gas turbine engines. Technological thrusts in two major areas are under way to meet the primary objective of conserving the use of strategic materials in nickelbase superalloys. These thrusts consist of strategic element substitution and alternative material identification. The program emphasizes cooperative research teams involving NASA Lewis Research Center, universities, and industry. The adoption of refractory metals in nickel-base superalloys is summarized including their roles in mechanical strengthening and environmental resistance; current research activities under way in the COSAM Program are presented as well as research findings to date.

2004-07-01

Although differences in self-conception across cultures have been well researched, regional differences within a culture have escaped attention. The present study examined individual, relational, and collective selves, which capture people's conceptions of themselves in relation to their goals, significant others, and in groups, comparing Australians and Japanese participants living in regional cities and metropolitan areas. Culture, gender, and urbanism were found to be related to individual, relational, and collective selves, respectively. Australians emphasized individual self more than Japanese, women stressed relational self more than men, and residents in regional cities regarded collective self as more important than their counterparts in metropolitan areas. These findings provide support for the tripartite division of the self and suggest a need to construct a culture theory that links self and societal processes.

Design principles for achieving integrated healthcare information systems.

2013-03-01

Achieving integrated healthcare information systems has become a common goal for many countries in their pursuit of obtaining coordinated and comprehensive healthcare services. This article focuses on how a small local project termed 'Standardized pull of patient data' expanded and is now used on a large scale providing a majority of hospitals, general practitioners and citizens across Denmark with the possibility of accessing healthcare data from different electronic patient record systems and other systems. I build on design theory for information infrastructures, as presented by Hanseth and Lyytinen, to examine the design principles that facilitated this smallscale project to expand and become widespread. As a result of my findings, I outline three lessons learned that emphasize: (i) principles of flexibility, (ii) expansion from the installed base through modular strategies and (iii) identification of key healthcare actors to provide them with immediate benefits.

Associative fear learning and perceptual discrimination: a perceptual pathway in the development of chronic pain.

PubMed

Zaman, Jonas; Vlaeyen, Johan W S; Van Oudenhove, Lukas; Wiech, Katja; Van Diest, Ilse

2015-04-01

Recent neuropsychological theories emphasize the influence of maladaptive learning and memory processes on pain perception. However, the precise relationship between these processes as well as the underlying mechanisms remain poorly understood; especially the role of perceptual discrimination and its modulation by associative fear learning has received little attention so far. Experimental work with exteroceptive stimuli consistently points to effects of fear learning on perceptual discrimination acuity. In addition, clinical observations have revealed that in individuals with chronic pain perceptual discrimination is impaired, and that tactile discrimination training reduces pain. Based on these findings, we present a theoretical model of which the central tenet is that associative fear learning contributes to the development of chronic pain through impaired interoceptive and proprioceptive discrimination acuity.

The NASA/Industry Design Analysis Methods for Vibrations (DAMVIBS) Program - A government overview. [of rotorcraft technology development using finite element method

NASA Technical Reports Server (NTRS)

Kvaternik, Raymond G.

1992-01-01

An overview is presented of government contributions to the program called Design Analysis Methods for Vibrations (DAMV) which attempted to develop finite-element-based analyses of rotorcraft vibrations. NASA initiated the program with a finite-element modeling program for the CH-47D tandem-rotor helicopter. The DAMV program emphasized four areas including: airframe finite-element modeling, difficult components studies, coupled rotor-airframe vibrations, and airframe structural optimization. Key accomplishments of the program include industrywide standards for modeling metal and composite airframes, improved industrial designs for vibrations, and the identification of critical structural contributors to airframe vibratory responses. The program also demonstrated the value of incorporating secondary modeling details to improving correlation, and the findings provide the basis for an improved finite-element-based dynamics design-analysis capability.

Borowka, S; Greiner, N; Heinrich, G; Jones, S P; Kerner, M; Schlenk, J; Schubert, U; Zirke, T

2016-07-01

We present the calculation of the cross section and invariant mass distribution for Higgs boson pair production in gluon fusion at next-to-leading order (NLO) in QCD. Top-quark masses are fully taken into account throughout the calculation. The virtual two-loop amplitude has been generated using an extension of the program GoSam supplemented with an interface to Reduze for the integral reduction. The occurring integrals have been calculated numerically using the program SecDec. Our results, including the full top-quark mass dependence for the first time, allow us to assess the validity of various approximations proposed in the literature, which we also recalculate. We find substantial deviations between the NLO result and the different approximations, which emphasizes the importance of including the full top-quark mass dependence at NLO.

Stereotype-based faultlines and out-group derogation in diverse teams: The moderating roles of task stereotypicality and need for cognition.

PubMed

Stanciu, Adrian

2017-01-01

Alignment of individuals on more than one diversity attribute (i.e., faultlines) may lead to intergroup biases in teams, disrupting the efficiency expectancies. Research has yet to examine if this can be a consequence of a stereotypical consistency between social and information attributes of diversity. The present study tests the hypothesis that, in a team with a stereotype-based faultline (a stereotypical consistency between gender and skills), there is increased out-group derogation compared to a team with a stereotype-inconsistent faultline. Furthermore, the study proposes that tasks can activate stereotypes, and the need for cognition dictates whether stereotypes are applied. The findings confirm the hypothesis and additionally provide evidence that tasks that activate gender stereotypes emphasize out-group derogation, especially for team members with low need for cognition.

The environmental Kuznets curve in the presence of corruption in developing countries.

Masron, Tajul Ariffin; Subramaniam, Yogeeswari

2018-05-01

Environmental degradation is at an alarming level in developing economies. The present paper examines the direct and indirect impacts of corruption on environmental deterioration using the panel data of 64 developing countries. Adopting the generalized method of moments (GMM) technique, the paper finds evidence that corruption exhibits a positive impact on pollution. Subsequently, there is also evidence indicating that the level of pollution tends to be higher in countries with a higher level of corruption, eliminating the effectiveness of income effect on environmental preservation. These results also suggest that environmental degradation is monotonically increasing with higher corruption and invalidate the presence of the EKC. Hence, a policy focuses that an anti-corruption particularly in the environmental and natural resources sector needs to be emphasized and enforced in order to reduce or possibly to totally eliminate the rent for corruption.

Encephalocraniocutaneous lipomatosis with calvarial exostosis - Case report and review of literature

PubMed Central

Thakur, Shruti; Thakur, Vijay; Sood, Ram Gopal; Thakur, Charu Smita; Khanna, Shweta

2013-01-01

Encephalocraniocutaneous lipomatosis (ECCL), also known as Haberland syndrome, is a rare syndrome with unknown etiology. The syndrome is characterized by a triad of unique cutaneous, ocular, and central nervous system (CNS) manifestations. The cutaneous hallmark, nevus psiloliparus (NP), along with overlying alopecia is a constant feature. Choristoma of the eyelid is the most common ocular manifestation, while intracranial lipoma is the predominant CNS finding. Genetic counseling is required to emphasize that the disorder, although congenital, is not inheritable. We present a 21-year-old female with cutaneous, ocular, and CNS features satisfying the diagnostic criteria for ECCL. To our knowledge, this is the first case of ECCL having a large temporal exostosis. The objective of this article is to better understand the phenotypic spectrum of this syndrome whose molecular basis is still unknown. PMID:24604937

A model of self-regulation for control of chronic disease.

Clark, Noreen M; Gong, Molly; Kaciroti, Niko

2014-10-01

Chronic disease poses increasing threat to individual and community health. The day-to-day manager of disease is the patient who undertakes actions with the guidance of a clinician. The ability of the patient to control the illness through an effective therapeutic plan is significantly influenced by social and behavioral factors. This article presents a model of patient management of chronic disease that accounts for intrapersonal and external influences on management and emphasizes the central role of self-regulatory processes in disease control. Asthma serves as a case for exploration of the model. Findings from a 5-year study of 637 children with asthma and their care-taking parents supported that the self-regulation elements of the model were reasonably stable over time and baseline values were predictive of important disease management outcomes. © 2014 Society for Public Health Education.

In their monograph, DiPietro, Costigan, and Voegtline present an important and thoughtful portrait of low-risk fetal development during the last trimester of gestation, and they also pay tribute to the Fels Longitudinal Study investigators' early work in this area. In this commentary, the history and legacy of the Fels Institute is further explored within the broader context of fetal research, and DiPietro et al.'s findings are placed in alignment with contemporary dynamic systems' theoretical approaches that emphasize longitudinal analysis of emergent behavior and process during early development. The commentary puts forth the assertion that the work reported by DiPietro and her colleagues tells a story that sets the stage for a new generation of technology-enhanced and culturally expanded investigations of fetal behavior. © 2015 The Society for Research in Child Development, Inc.

The combination of loss of habitat, human population encroachment, and increased demand of select nonhuman primates for biomedical research has significantly affected populations. There remains a need for knowledge and expertise in understanding background findings as related to the age, source, strain, and disease status of nonhuman primates. In particular, for safety/biomedical studies, a broader understanding and documentation of lesions would help clarify background from drug-related findings. A workshop and a minisymposium on spontaneous lesions and diseases in nonhuman primates were sponsored by the concurrent Annual Meetings of the American College of Veterinary Pathologists and the American Society for Veterinary Clinical Pathology held December 3–4, 2011, in Nashville, Tennessee. The first session had presentations from Drs Lowenstine and Montali, pathologists with extensive experience in wild and zoo populations of nonhuman primates, which was followed by presentations of 20 unique case reports of rare or newly observed spontaneous lesions in nonhuman primates (see online files for access to digital whole-slide images corresponding to each case report at http://www.scanscope.com/ACVP%20Slide%20 Seminars/2011/Primate%20Pathology/view.apml). The minisymposium was composed of 5 nonhuman-primate researchers (Drs Bradley, Cline, Sasseville, Miller, Hutto) who concentrated on background and spontaneous lesions in nonhuman primates used in drug safety studies. Cynomolgus and rhesus macaques were emphasized, with some material presented on common marmosets. Congenital, acquired, inflammatory, and neoplastic changes were highlighed with a focus on clinical, macroscopic, and histopathologic findings that could confound the interpretation of drug safety studies.

Spiritual and natural etiologies on a Polynesian outlier in Papua New Guinea.

PubMed

Feinberg, R

1990-01-01

Several writers have challenged recently the long-held contention that non-Western peoples tend to emphasize spirits, sorcerers, and other supernatural forces in their explanations for the cause of illness. Here, I examine indigenous theories of illness-causation on Nukumanu, a Polynesian outlier atoll in Papua New Guinea. Although Nukumanu invoke mundane as well as supernatural explanations, their major preoccupation is with spirits as etiological agents. In this light, I suggest a number of potential reasons for the difference between my findings on Nukumanu and those of commentators who have emphasized naturalistic etiologies among the peoples they have studied. In addition to real ethnographic variation, I argue that a major reason for the difference lies in the level of causality (instrumental as opposed to efficient and ultimate) sought by various investigators.

What makes African American health disparities newsworthy? An experiment among journalists about story framing

PubMed Central

Hinnant, Amanda; Oh, Hyun Jee; Caburnay, Charlene A.; Kreuter, Matthew W.

2011-01-01

News stories reporting race-specific health information commonly emphasize disparities between racial groups. But recent research suggests this focus on disparities has unintended effects on African American audiences, generating negative emotions and less interest in preventive behaviors (Nicholson RA, Kreuter MW, Lapka C et al. Unintended effects of emphasizing disparities in cancer communication to African-Americans. Cancer Epidemiol Biomarkers Prev 2008; 17: 2946–52). They found that black adults are more interested in cancer screening after reading about the progress African Americans have made in fighting cancer than after reading stories emphasizing disparities between blacks and whites. This study builds on past findings by (i) examining how health journalists judge the newsworthiness of stories that report race-specific health information by emphasizing disparities versus progress and (ii) determining whether these judgments can be changed by informing journalists of audience reactions to disparity versus progress framing. In a double-blind-randomized experiment, 175 health journalists read either a disparity- or progress-framed story on colon cancer, preceded by either an inoculation about audience effects of such framing or an unrelated (i.e. control) information stimuli. Journalists rated the disparity-frame story more favorably than the progress-frame story in every category of news values. However, the inoculation significantly increased positive reactions to the progress-frame story. Informing journalists of audience reactions to race-specific health information could influence how health news stories are framed. PMID:21911844

Solitary neurofibroma located in the hilum of the liver is extremely rare, particularly without neurofibromatosis. We herein report a case of hilar biliary neurofibroma without signs of von Recklinghausen's disease. A 36-year-old man was admitted to our department with progressive jaundice. The case was diagnosed as hilar cholangiocarcinoma based on preoperative imaging. The patient consequently received a Roux-en-Y hepaticojejunostomy and was confirmed with neurofibroma pathologically. This is the first reported imaging finding of hilar biliary neurofibroma using contrast-enhanced ultrasound, emphasizing the differential diagnosis of biliary tumors.

The Neurological Complications of Nutritional Deficiency following Bariatric Surgery

PubMed Central

Becker, Danielle A.; Balcer, Laura J.; Galetta, Steven L.

2012-01-01

Neurologic complications of bariatric surgery have become increasingly recognized with the rising numbers of procedures and the increasing prevalence of obesity in the US. Deficits are most commonly seen with thiamine, vitamin B12, folate, vitamin D, vitamin E, and copper deficiencies. The neurological findings observed with these nutritional deficiencies are variable and include encephalopathy, optic neuropathy, myelopathy, polyradiculoneuropathy, and polyneuropathy. We review the neurological complications of bariatric surgery and emphasize that these findings may vary based on the specific type of bariatric surgery and time elapsed from the procedure.

2016-11-22

Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation syndrome is a rare pediatric disorder with a variable sequence of clinical presentations, undefined etiology, and high risk of mortality. Our patient presented an unusual course of the disease accompanied by a homogenous mild enlargement of her pituitary gland with an intact pituitary-endocrine axis which, to the best of our knowledge, represents a new finding in rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation syndrome. We present a documented case of a 4 years and 8-month-old Syrian Arabic girl with a distinctive course of signs and symptoms of rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation syndrome accompanied by mature ganglioneuroma in her chest, a homogenous mild enlargement of her pituitary gland, generalized cortical brain atrophy, and seizures. Three months after her first marked symptoms were noted she had a sudden progression of severe respiratory distress that ended with her death. The findings of this case could increase our understanding of the pathogenetic mechanisms of rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation, and place more emphases on pediatricians to consider rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation syndrome whenever early rapid onset of obesity, associated with any malfunction, is observed in children. This knowledge could be lifesaving for children with rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation syndrome.

Anticipatory processing in social anxiety: Investigation using attentional control theory.

PubMed

Sluis, Rachel A; Boschen, Mark J; Neumann, David L; Murphy, Karen

2017-12-01

Cognitive models of social anxiety disorder (SAD) emphasize anticipatory processing as a prominent maintaining factor occurring before social-evaluative events. While anticipatory processing is a maladaptive process, the cognitive mechanisms that underlie ineffective control of attention are still unclear. The present study tested predictions derived from attentional control theory in a sample of undergraduate students high and low on social anxiety symptoms. Participants were randomly assigned to either engage in anticipatory processing prior to a threat of a speech task or a control condition with no social evaluative threat. After completing a series of questionnaires, participants performed pro-saccades and antisaccades in response to peripherally presented facial expressions presented in either single-task or mixed-task blocks. Correct antisaccade latencies were longer than correct pro-saccade latencies in-line with attentional control theory. High socially anxious individuals who anticipated did not exhibit impairment on the inhibition and shifting functions compared to high socially anxious individuals who did not anticipate or low socially anxious individuals in either the anticipatory or control condition. Low socially anxious individuals who anticipated exhibited shorter antisaccade latencies and a switch benefit compared to low socially anxious individuals in the control condition. The study used an analogue sample; however findings from analogue samples are generally consistent with clinical samples. The findings suggest that social threat induced anticipatory processing facilitates executive functioning for low socially anxious individuals when anticipating a social-evaluative situation.

Solvang, Per Koren; Fougner, Marit

2016-11-01

The patient's active participation in treatment and rehabilitation represents a cultural change in clinical practice as well as a major change in physiotherapist and patient roles. This article presents findings from a study aimed at gaining a better understanding of how physiotherapists in actual practice understand their interactions with patients during the treatment process. This article reports on the findings from focus-group interviews with physiotherapists working in three different settings. Analyses of the interview data identified three modes of physiotherapy practice. In one, physiotherapists educate their patients to be self-managing in conducting exercise programs based on sound evidence. Educational films available on the Internet are included in these efforts to teach patients. In another, physiotherapists emphasize the importance of a close relationship to the patient. A good personal chemistry is believed to improve the treatment process. And finally, what physiotherapists learn about the living conditions and the biographies of their patients was shown to be very important. Understanding the importance of the life-world and taking this into consideration in the treatment process were factors considered to be central to good practice. The article concludes with a discussion linking these findings to those of other studies identifying those factors contributing to our knowledge of what is involved in biopsychosocial practice in physiotherapy.

Atypical lymphoplasmacytic immunoblastic proliferation (ALPIB) is a rare lymphoproliferative disorder (LPD) associated with autoimmune disease (AID). To further clarify the clinicopathologic, immunohistological, and genotypic findings of ALPIB in lymph nodes associated with well-documented AIDs, 9 cases are presented. These 9 patients consisted of 4 patients with systemic lupus erythematosus, 3 patients with rheumatoid arthritis, and one case each with Sjögren's syndrome and dermatomyositis. All 9 patients were females aged from 25 to 71 years with a median age of 49 years. Four cases presented with lymphadenopathy as the initial manifestation. In 4 patients, immunosuppressive drugs were administered before the onset of lymph node lesion. However, none of the 9 patients received methotrexate therapy. The present 9 cases were characterized by : (i) prominent lymphoplasmacytic and B-immunoblastic infiltration ; (ii) absence of pronounced arborizing vascular proliferation ; (iii) absence of CD10(+) "clear cells" ; (iv) presence of hyperplastic germinal center in 7 cases ; (v) immunohistochemistry, flow cytometry, and polymerase chain reaction demonstrated a reactive nature of the T- and B-lymphocytes ; and (vi) on in situ hybridization, there were no Epstein-Barr virus -infected lymphoid cells in any of the 9 cases. Overall 5-year survival of our patients was 83%. The combination of clinical, immunophenotypic, and genotypic findings indicated that the present 9 cases can be regarded as having an essentially benign reactive process. Finally, we emphasized that ALPIB should be added to the differential diagnostic problems of atypical LPDs, particularly lymph node lesions of IgG4-related diseases.

Does Stigmatized Social Risk Lead to Denialism? Results from a Survey Experiment on Race, Risk Perception, and Health Policy in the United States

PubMed Central

Dunham, Yarrow; Lieberman, Evan S.; Snell, Steven A.

2016-01-01

In this article, we report findings from an original survey experiment investigating the effects of different framings of disease threats on individual risk perceptions and policy priorities. We analyze responses from 1,946 white and African-American participants in a self-administered, web-based survey in the United States. We sought to investigate the effects of: 1) frames emphasizing disparities in the racial prevalence of disease and 2) frames emphasizing non-normative (blameworthy or stigmatized) behavioral risk factors. We find some evidence that when treated with the first frame, African-Americans are more likely to report higher risk of infection (compared to an African-American control group and to whites receiving the same treatment); and that whites are more likely to report trust in government data (compared to a White control group and to African-Americans receiving the same treatment). Notwithstanding, we find no support for our hypotheses concerning the interactive effects of providing both frames, which was a central motivation for our study. We argue that this may be due to very large differences in risk perception at baseline (which generate limits on possible treatment effects) and the fact that in the context of American race relations, it may not be possible to fully differentiate racialized and stigmatized frames.

What must I do to succeed?: Narratives from the US Premedical Experience

PubMed Central

Lin, Katherine Y.; Anspach, Renee R.; Crawford, Brett; Parnami, Sonali; Fuhrel-Forbis, Andrea; De Vries, Raymond G.

2014-01-01

Medical sociologists have long been fascinated with the process through which laypersons are transformed into physicians, uncovering the ways in which one learns, not just the facts of medical science, but also how to be a physician. Despite this abiding focus on socialization, nearly all of the literature on this process in the US is informed by studies of the medical school and residency years, with almost no empirical attention paid to the premedical years. Our study addresses this gap in knowledge. To better understand the premedical years we conducted 49 in-depth interviews with premedical students at a selective, public Midwestern university. We found that students understand and explain decisions made during the premedical years with narratives that emphasize the qualities of achievement-orientation, perseverance, and individualism. We also find that these qualities are also emphasized in narratives employed to account for the choice to collaborate with, or compete against, premedical peers. Examination of premedical narratives, and the qualities they emphasize, enriches our understanding of how premedical education shapes a physician's moral development, and underscores the need to include the premedical years in our accounts of “becoming a doctor.” PMID:25163642

Sense of community responsibility in community collaboratives: advancing a theory of community as resource and responsibility.

PubMed

Nowell, Branda; Boyd, Neil M

2014-12-01

This paper contributes to the growing body of scholarship aimed at advancing our understanding of the experience of community by empirically investigating sense of community responsibility (SOC-R) in relation to traditional measures of sense of community (SOC) and indices of satisfaction, engagement, and leadership in interorganizational collaborative settings. Findings support the proposition that, although both are related to the experience of community, SOC and SOC-R emphasize different aspects of that experience and operate under different theoretical mechanisms of influence. SOC emphasizes community as a resource which was found to be a more salient aspect in differentiating those who will be more or less satisfied with their experience. In addition, SOC was found to predict general participation in a community collaborative. SOC-R emphasizes the experience of community as a responsibility which appears to be a stronger predictor in explaining higher order engagement requiring greater investment of time and resources. Even more importantly, this study indicates that SOC-R is uniquely equipped to help us advance models of community leadership. As such, it represents an important contribution to expanding our understanding of the factors that drive members' willingness to give of themselves toward collective aims.

Conducting a user-centered information needs assessment: the Via Christi Libraries' experience.

Perley, Cathy M; Gentry, Camillia A; Fleming, A Sue; Sen, Kristin M

2007-04-01

The research sought to provide evidence to support the development of a long-term strategy for the Via Christi Regional Medical Center Libraries. An information needs assessment was conducted in a large medical center serving approximately 5,900 physicians, clinicians, and nonclinical staff in 4 sites in 1 Midwestern city. Quantitative and qualitative data from 1,295 self-reporting surveys, 75 telephone interviews, and 2 focus groups were collected and analyzed to address 2 questions: how could the libraries best serve their patrons, given realistic limitations on time, resources, and personnel, and how could the libraries best help their institution improve patient care and outcomes? Clinicians emphasized the need for "just in time" information accessible at the point of care. Library nonusers emphasized the need to market library services and resources. Both clinical and nonclinical respondents emphasized the need for information services customized to their professional information needs, preferences, and patterns of use. Specific information needs in the organization were identified. The results of this three-part, user-centered information needs assessment were used to develop an evidence-based strategic plan. The findings confirmed the importance of promoting library services in the organization and suggested expanded, collaborative roles for hospital librarians.

Sexuality education policies and sexually transmitted disease rates in the United States of America.

PubMed

Hogben, M; Chesson, H; Aral, S O

2010-04-01

The aim of the study was to test for relationships between state-level sex educational policies and sexually transmitted disease (STD) rates. We analysed US case reports of gonorrhoea and chlamydial infection for 2001-2005 against state policies for abstinence coverage in sexuality education, using the proportion of the population per state who identified as black (aged 15-24 years) as a covariate. We also tested for effects on 15-19 year olds versus 35-39 year olds and tuberculosis rates (the latter to ensure findings applied only to STD). States with no mandates for abstinence had the lowest mean rates of infection among the overall population and among adolescents. States with mandates emphasizing abstinence had the highest rates; states with mandates to cover (but not emphasize) abstinence fell in between. Rates in some states covering abstinence changed faster than in others, as reflected in sharper declines (gonorrhoea) or slower increases (chlamydial infection). These effects were not shown for tuberculosis or 35-39 year olds. Having no abstinence education policy has no apparent effect on STD rates for adolescents. For states with elevated rates, policies mandating coverage may be useful, although policies emphasizing abstinence show no benefit.

Alcohol Demand, Delayed Reward Discounting, and Craving in relation to Drinking and Alcohol Use Disorders

A behavioral economic approach to alcohol use disorders (AUDs) emphasizes both individual and environmental determinants of alcohol use. The current study examined individual differences in alcohol demand (i.e., motivation for alcohol under escalating conditions of price) and delayed reward discounting (i.e., preference for immediate small rewards compared to delayed larger rewards) in 61 heavy drinkers (62% with an AUD). In addition, based on theoretical accounts that emphasize the role of craving in reward valuation and preferences for immediate rewards, craving for alcohol was also examined in relation to these behavioral economic variables and the alcohol-related variables. Intensity of alcohol demand and delayed reward discounting were significantly associated with AUD symptoms, but not with quantitative measures of alcohol use, and were also moderately correlated with each other. Likewise, craving was significantly associated with AUD symptoms, but not with alcohol use, and was also significantly correlated with both intensity of demand and delayed reward discounting. These findings further emphasize the relevance of behavioral economic indices of motivation to alcohol use disorders and the potential importance of craving for alcohol in this relationship.

Single-Word Recognition Need Not Depend on Single-Word Features: Narrative Coherence Counteracts Effects of Single-Word Features that Lexical Decision Emphasizes.

PubMed

Teng, Dan W; Wallot, Sebastian; Kelty-Stephen, Damian G

2016-12-01

Research on reading comprehension of connected text emphasizes reliance on single-word features that organize a stable, mental lexicon of words and that speed or slow the recognition of each new word. However, the time needed to recognize a word might not actually be as fixed as previous research indicates, and the stability of the mental lexicon may change with task demands. The present study explores the effects of narrative coherence in self-paced story reading to single-word feature effects in lexical decision. We presented single strings of letters to 24 participants, in both lexical decision and self-paced story reading. Both tasks included the same words composing a set of adjective-noun pairs. Reading times revealed that the tasks, and the order of the presentation of the tasks, changed and/or eliminated familiar effects of single-word features. Specifically, experiencing the lexical-decision task first gradually emphasized the role of single-word features, and experiencing the self-paced story-reading task afterwards counteracted the effect of single-word features. We discuss the implications that task-dependence and narrative coherence might have for the organization of the mental lexicon. Future work will need to consider what architectures suit the apparent flexibility with which task can accentuate or diminish effects of single-word features.

For decades, public warning messages have been relayed via broadcast information channels, including radio and television; more recently, risk communication channels have expanded to include social media sites, where messages can be easily amplified by user retransmission. This research examines the factors that predict the extent of retransmission for official hazard communications disseminated via Twitter. Using data from events involving five different hazards, we identity three types of attributes--local network properties, message content, and message style--that jointly amplify and/or attenuate the retransmission of official communications under imminent threat. We find that the use of an agreed-upon hashtag and the number of users following an official account positively influence message retransmission, as does message content describing hazard impacts or emphasizing cohesion among users. By contrast, messages directed at individuals, expressing gratitude, or including a URL were less widely disseminated than similar messages without these features. Our findings suggest that some measures commonly taken to convey additional information to the public (e.g., URL inclusion) may come at a cost in terms of message amplification; on the other hand, some types of content not traditionally emphasized in guidance on hazard communication may enhance retransmission rates.

Mathematics teachers' conceptions about modelling activities and its reflection on their beliefs about mathematics

Shahbari, Juhaina Awawdeh

2018-07-01

The current study examines whether the engagement of mathematics teachers in modelling activities and subsequent changes in their conceptions about these activities affect their beliefs about mathematics. The sample comprised 52 mathematics teachers working in small groups in four modelling activities. The data were collected from teachers' Reports about features of each activity, interviews and questionnaires on teachers' beliefs about mathematics. The findings indicated changes in teachers' conceptions about the modelling activities. Most teachers referred to the first activity as a mathematical problem but emphasized only the mathematical notions or the mathematical operations in the modelling process; changes in their conceptions were gradual. Most of the teachers referred to the fourth activity as a mathematical problem and emphasized features of the whole modelling process. The results of the interviews indicated that changes in the teachers' conceptions can be attributed to structure of the activities, group discussions, solution paths and elicited models. These changes about modelling activities were reflected in teachers' beliefs about mathematics. The quantitative findings indicated that the teachers developed more constructive beliefs about mathematics after engagement in the modelling activities and that the difference was significant, however there was no significant difference regarding changes in their traditional beliefs.

Access to Aid-in-Dying in the United States: Shifting the Debate From Rights to Justice.

PubMed

Buchbinder, Mara

2018-06-01

Much of the literature on aid-in-dying (AID) has drawn heavily on rights-based ethical and legal frameworks that emphasize patients' rights of self-determination in end-of-life decision-making. Less attention has focused on how terminally ill people actually experience such putative rights once they are legally authorized. This analytic essay draws on findings from the Vermont Study on Aid-in-Dying, an ethnographic study of the implementation of AID in Vermont (2015-2017). First, I show that terminally ill people can face a range of barriers to accessing AID in permissive jurisdictions, and that access to AID is mediated by various inequalities endemic to US health care, as well as some that are unique to AID. I then build on these findings to examine the utility of the concept of justice for public health scholarship on AID. By integrating empirical, ethical, and policy analysis, I reframe rights-based frameworks that emphasize the role of individual choice and decision-making at the end of life. In doing so, I draw attention to health care justice as a neglected issue in public health perspectives on AID.

Using drama to improve person-centred dementia care.

Kontos, Pia C; Mitchell, Gail J; Mistry, Bhavnita; Ballon, Bruce

2010-06-01

We implemented a 12-week drama-based educational intervention to introduce to dementia practitioners person-centred care that emphasizes the notion of embodied selfhood (defined as non-verbal self-expression). Person-centred dementia care guidelines emphasize the assessment of individual needs, and where appropriate, the use of non-pharmacological interventions before resorting to pharmacological management. However, dementia care is not consistent with these guidelines suggesting conceptual limitations and reliance on passive knowledge translation strategies. Focus groups and semi-structured interviews with practitioners (n = 24) in two nursing homes in central Canada were undertaken to assess the effectiveness of the drama-based components of the intervention. Our findings suggest that drama was effective as an educational modality, and helped implement the person-centred approach into practice. Significant practice outcomes included: new awareness that residents' body movements and dispositions can convey meaning; seeking biographical information from families; increased time efficiency; and supporting residents' independence. Our findings make an important contribution to person-centred dementia care by broadening the notion of personhood, and by facilitating implementation using drama. As an enhancement of person-centred care, the support of embodied selfhood may significantly improve residents' quality of life, quality of care, and practitioners' care-giving experience. © 2010 Blackwell Publishing Ltd.

Drama-induced affect and pain sensitivity.

Zillmann, D; de Wied, M; King-Jablonski, C; Jenzowsky, S

1996-01-01

This study was conducted to examine the pain-ameliorating and pain-sensitizing effects of exposure to emotionally engaging drama. Specifically, the consequences for pain sensitivity of exposure to dramatic expositions differing in both excitatory and hedonic qualities were determined. Hedonically negative, neutral, and positive affective states were induced in male respondents by exposure to excerpts from cinematic drama. Pain sensitivity was assessed by the cuff-pressure procedure before and after exposure and by the cold pressor test after exposure only. When compared against the control condition, pain sensitivity diminished under conditions of hedonically positive affect. An inverse effect was suggested for hedonically negative conditions, but proved tentative and statistically unreliable. The findings are consistent with earlier demonstrations of mood effects on pain sensitivity. Unlike inconclusive earlier findings concerning the magnitude of directional effects, however, they suggest an asymmetry that emphasizes the pain-ameliorating effect of positive affects while lending little, if any, support to the proposal of a pain-sensitizing effect of negative affects. The investigation did not accomplish the intended creation of conditions necessary to test the proposal that heightened sympathetic activity diminishes pain sensitivity. The utility of a rigorous determination of this hypothesized relationship is emphasized, and procedures for a viable test of the proposal are suggested.

Pulmonary tumorlets with surrounding fibrous tissue--suspected carcinoma: case report and review of the literature.

Pulmonary tumorlets are small, often multiple nodular proliferations of pulmonary neuroendocrine cells. They are common incidental findings in chronic inflammatory pulmonary diseases. They can also be found in normal lung parenchyma and as one part of the continuum known as diffuse idiopathic pulmonary neuroendocrine cell hyperplasia. In many cases, they are incidental histologic findings of no importance or clinical consequences, or they can be associated with a very slow progression of either obstructive or mixed obstructive/restrictive impairment with good prognosis. Only rarely, they metastasize to an adjacent lymph node or produce ectopic neuroendocrine products. When found during diagnostic examination, they represent a doubt to be a malignant tumor until proven otherwise, which is often impossible without biopsy or surgical removal of the adjacent lung lobe. Hereby, we present a patient with a persistent nodular lung structure after being treated for nonspecific symptoms, cough with non purulent sputum and pain among the scapulae, for a period of one month. He had otherwise normal clinical and laboratory findings, except for a mild mixed obstructive/restrictive pattern of impairment that was shown by lung spirometry. After 8 months, he underwent lobectomy of the medial lobe of the lung with partial lymphadenectomy, since the diagnostic methods applied could not define the nature of lung nodular infiltration. Histologic examination showed a few tumorlets surrounded by the fibrous tissue with a very dense lymphocyte infiltration. We present a review of the literature and emphasize the necessity to include tumorlets with adjacent fibrosis as part of the differential diagnosis of a solitary nodular lung structure.

Color-blind racial ideology: theory, training, and measurement implications in psychology.

Synthesizing the interdisciplinary literature, we characterize color-blind racial ideology (CBRI) as consisting of two interrelated domains: color-evasion (i.e., denial of racial differences by emphasizing sameness) and power-evasion (i.e., denial of racism by emphasizing equal opportunities). Mounting empirical data suggest that the color-evasion dimension is ineffective and in fact promotes interracial tension and potential inequality. CBRI may be conceived as an ultramodern or contemporary form of racism and a legitimizing ideology used to justify the racial status quo. Four types of CBRI are described: denial of (a) race, (b) blatant racial issues, (c) institutional racism, and (d) White privilege. We discuss empirical findings suggesting a relationship between CBRI and increased racial prejudice, racial anger, and racial fear. Implications for education, training, and research are provided. © 2013 APA, all rights reserved.

Religion is commonly defined as a set of rules, developed as part of a culture. Here we provide evidence that practice in following these rules systematically changes the way people attend to visual stimuli, as indicated by the individual sizes of the global precedence effect (better performance to global than to local features). We show that this effect is significantly reduced in Calvinism, a religion emphasizing individual responsibility, and increased in Catholicism and Judaism, religions emphasizing social solidarity. We also show that this effect is long-lasting (still affecting baptized atheists) and that its size systematically varies as a function of the amount and strictness of religious practices. These findings suggest that religious practice induces particular cognitive-control styles that induce chronic, directional biases in the control of visual attention. Copyright 2010 Elsevier B.V.

Risk beliefs and self-efficacy play important roles in explaining smoking-related outcomes and are important to target in tobacco control interventions. However, information is lacking about the underlying beliefs that drive these constructs. The present study investigated the interrelationships among young adult smokers' beliefs about the nature of nicotine addiction and smoking-related affect and cognitions (i.e., feelings of risk, worry about experiencing the harms of smoking, self-efficacy of quitting, and intentions to quit). Smokers (n = 333) were recruited from two large universities. Results showed that quit intentions were associated with feelings of risk, but not with worry or self-efficacy. Furthermore, higher feelings of risk were associated with lower beliefs that addiction is an inevitable consequence of smoking and with lower beliefs that the harms of smoking are delayed. This suggests that it is important for health messages to counter the possible negative effects of messages that strongly emphasize the addictiveness of nicotine, possibly by emphasizing the importance of quitting earlier rather than later. The findings also add to the evidence base that feelings of risk are powerful predictors of behavioral intentions. Furthermore, our results suggest that in some circumstances, feelings of risk predict quit intentions beyond that predicted by worry and self-efficacy. Gaining additional understanding of the tobacco-related beliefs that can increase feelings of risk and incorporating those beliefs into educational campaigns may improve the quality of such campaigns and reduce tobacco use.

[Inequities in access to information and inequities in health].

Filho, Alberto Pellegrini

2002-01-01

This piece presents evidence that inequities in information are an important determinant of health inequities and that eliminating these inequities in access to information, especially by using new information and communication technologies (ICTs), could represent a significant advance in terms of guaranteeing the right to health for all. The piece reviews the most important international scientific research findings on the determinants of the health of populations, emphasizing the role of socioeconomic inequities and of deteriorating social capital as factors that worsen health conditions. It is noteworthy that Latin America has both socioeconomic inequities and major sectors of the population living in poverty. Among the fundamental strategies for overcoming the inequalities and the poverty are greater participation by the poor in civic life and the strengthening of social capital. The contribution that the new ICTs could make to these strategies is analyzed, and the Virtual Health Library (VHL) is discussed. Coordinated by the Latin American and Caribbean Center on Health Sciences Information (BIREME), the VHL is a contribution by the Pan American Health Organization that takes advantage of the potential of ICTs to democratize information and knowledge and consequently promote equity in health. The "digital gap" is discussed as something that can produce inequity itself and also increase other inequities, including ones in health. Prospects are discussed for overcoming this gap, emphasizing the role that governments and international organizations should play in order to expand access to the global public good that information for social development is.

Overcoming confirmation bias in causal attribution: a case study of antibiotic resistance risks.

Cox, Louis Anthony Tony; Popken, Douglas A

When they do not use formal quantitative risk assessment methods, many scientists (like other people) make mistakes and exhibit biases in reasoning about causation, if-then relations, and evidence. Decision-related conclusions or causal explanations are reached prematurely based on narrative plausibility rather than adequate factual evidence. Then, confirming evidence is sought and emphasized, but disconfirming evidence is ignored or discounted. This tendency has serious implications for health-related public policy discussions and decisions. We provide examples occurring in antimicrobial health risk assessments, including a case study of a recently reported positive relation between virginiamycin (VM) use in poultry and risk of resistance to VM-like (streptogramin) antibiotics in humans. This finding has been used to argue that poultry consumption causes increased resistance risks, that serious health impacts may result, and therefore use of VM in poultry should be restricted. However, the original study compared healthy vegetarians to hospitalized poultry consumers. Our examination of the same data using conditional independence tests for potential causality reveals that poultry consumption acted as a surrogate for hospitalization in this study. After accounting for current hospitalization status, no evidence remains supporting a causal relationship between poultry consumption and increased streptogramin resistance. This example emphasizes both the importance and the practical possibility of analyzing and presenting quantitative risk information using data analysis techniques (such as Bayesian model averaging (BMA) and conditional independence tests) that are as free as possible from potential selection, confirmation, and modeling biases.

Fusing Quantitative Requirements Analysis with Model-based Systems Engineering

2006-01-01

A vision is presented for fusing quantitative requirements analysis with model-based systems engineering. This vision draws upon and combines emergent themes in the engineering milieu. "Requirements engineering" provides means to explicitly represent requirements (both functional and non-functional) as constraints and preferences on acceptable solutions, and emphasizes early-lifecycle review, analysis and verification of design and development plans. "Design by shopping" emphasizes revealing the space of options available from which to choose (without presuming that all selection criteria have previously been elicited), and provides means to make understandable the range of choices and their ramifications. "Model-based engineering" emphasizes the goal of utilizing a formal representation of all aspects of system design, from development through operations, and provides powerful tool suites that support the practical application of these principles. A first step prototype towards this vision is described, embodying the key capabilities. Illustrations, implications, further challenges and opportunities are outlined.

Error analysis of satellite attitude determination using a vision-based approach

Carozza, Ludovico; Bevilacqua, Alessandro

2013-09-01

Improvements in communication and processing technologies have opened the doors to exploit on-board cameras to compute objects' spatial attitude using only the visual information from sequences of remote sensed images. The strategies and the algorithmic approach used to extract such information affect the estimation accuracy of the three-axis orientation of the object. This work presents a method for analyzing the most relevant error sources, including numerical ones, possible drift effects and their influence on the overall accuracy, referring to vision-based approaches. The method in particular focuses on the analysis of the image registration algorithm, carried out through on-purpose simulations. The overall accuracy has been assessed on a challenging case study, for which accuracy represents the fundamental requirement. In particular, attitude determination has been analyzed for small satellites, by comparing theoretical findings to metric results from simulations on realistic ground-truth data. Significant laboratory experiments, using a numerical control unit, have further confirmed the outcome. We believe that our analysis approach, as well as our findings in terms of error characterization, can be useful at proof-of-concept design and planning levels, since they emphasize the main sources of error for visual based approaches employed for satellite attitude estimation. Nevertheless, the approach we present is also of general interest for all the affine applicative domains which require an accurate estimation of three-dimensional orientation parameters (i.e., robotics, airborne stabilization).

The Context of Graduate Student Preparation in Physics: professional roles of research and teaching

2004-05-01

This talk considers the role of graduate training from a broad perspective --- that of making professional physicists. Following Shulman's definition and characterization of 'professionals' [1], it may be observed that graduate student preparation in research follows a traditional and effective track of creating professionals. However, at the same time, other forms professional activity of physicists, notably teaching and educational practice, remain largely absent. This talk presents a model of the contextual nature of student learning that sheds light on why and how this division occurs. Given such attention to context, this talk then examines a graduate student program in physics that is designed to augment the traditional training of graduate students in order to more fully inform and prepare students for their future roles. Data are presented from a study of a local four-year implementation of the national Preparing Future Physics Faculty Program to document the structure, key features, and outcomes of the program. Results include a framework and general heuristics for successful implementation, and the impact of emphasizing education and physics education research. Among the findings, this graduate training program demonstrates one mechanism for infusing physics education research and its findings into the broader physics community. [1] Shulman.

The pathways of high school science teachers and policy efforts to alter the pipeline

Sass, Tim

2012-03-01

There is currently much interest in improving the quality of science education in K-12 schools and encouraging more students, particularly minorities and women, to pursue careers in STEM fields. Two interrelated issues are at the forefront: the quality of science teachers and the supply of science teachers. Education research in general finds that the single most important school-based factor affecting student achievement is teacher quality. While there is little evidence that teacher credentials matter for student achievement in the lower grades, there is at least some evidence that content knowledge is an important determinant of teacher quality in middle and secondary schools. However, little is known about the pre-service preparation of high school science teachers and how the training of science teachers affects their performance in the classroom. While there are many efforts underway to increase the supply of science teachers, little is known about the supply of science teachers from different pathways and the factors that lead science teachers to leave the profession. In this presentation I discuss recent work on the supply of teachers from alternative pathways, focusing on high school science teachers. I also summarize the literature on teacher quality and attrition, emphasizing the current state of knowledge on secondary school teachers. Finally, I present current policy initiatives and discuss the likelihood of their success given current research findings.

The investigation of veridical mood-congruent memory (MCM) in major depressive disorder (MDD) has been subject of many studies, whereas mood-congruent false memory has received comparatively little attention. The present study examined the influence of valence, personal relevance and the valence of the context of the learning material on true and false MCM in 20 inpatients with MDD and 20 healthy controls. Sixty positive, negative, neutral or personally relevant nouns were either combined with a positive, negative or neutral adjective. Word pairs were presented to participants in a learning trial. In a recognition task, participants had to identify the previously studied word pairs. A MCM effect could not be found for hits. However, in exploratory analyses, word pairs containing personally relevant nouns were more rated towards old by the patient relative to the control group. Furthermore, depressed patients tended to rate items more towards old than controls when the words were presented in a negative new context. Results are in line with previous findings in depression research emphasizing the role of mood-congruent false memories for mood disorders. Copyright © 2013 Elsevier Ireland Ltd.

2017-01-01

Sandfly fever, sometimes known as pappataci fever or Phlebotomus fever, is a vector transmitted viral illness with a history of affecting naïve military formations that travel through or fight in areas in which the infection is endemic. We present a series of 4 hospitalized cases of sandfly fever (2 presumptive, 2 laboratory confirmed) that were admitted to a Role 3 hospital in Afghanistan for evaluation and treatment following medical evacuation from a forward area for marked fevers and malaise. Laboratory evaluation of these cases was significant for leukopenia and thrombocytopenia, consistent with historical descriptions of sandfly fever. In the correct geographic and clinical setting, the finding of mild leukopenia among a cluster of febrile patients should prompt the clinician to at least consider a diagnosis of sandfly fever. A cluster investigation conducted by preventive medicine personnel identified numerous other presumed cases of sandfly fever in this forward special operations camp. Response efforts emphasized enforcement of standard vector-borne disease control measures by operational leadership in order to limit effect on tactical operations. We review historical instances of sandfly fever affecting military operations, and present a review of clinical presentation, transmission, management, and prevention.

Histamine has been incriminated as having a responsibility for intolerance reaction to wines. We have made a study by double blind oral provocation test to find the effect of ingestion of a histamine-rich (22.8 mg.l-1) and a histamine free wine in eight healthy subjects. Blood samples were taken at 0, 10, 30 and 45 minutes after ingestion of the wine for measurement of plasma histamine and methylhistamine. Urines were collected 5 hours before and 5 hours after ingestion for measurement of urinary methylhistamine. No subject presented a reaction of intolerance after ingestion of wine rich or poor in histamine. No change in plasma histamine and plasma and urinary methylhistamine was seen. This study shows that the amount of histamine in wine has no clinical or biological effect in healthy subjects, and this emphasized the efficiency in man of the systems for degradation of histamine that is absorbed by the alimentary tract.

2014-01-01

Interventions tailored to individual smoker characteristics have increasingly received attention in the tobacco control literature. The majority of tailored interventions are generated by computers and administered with printed materials or Web-based programs. The purpose of this study was to examine the tailoring activities of community lay health influencers who were trained to perform face-to-face brief tobacco cessation interventions. Eighty participants of a large-scale, randomized controlled trial completed a 6-week qualitative follow-up interview. A majority of participants (86%) reported that they made adjustments in their intervention behaviors based on individual smoker characteristics, their relationship with the smoker, and/or setting. Situational contexts (i.e., location and timing) primarily played a role after targeted smokers were selected. The findings suggest that lay health influencers benefit from a training curriculum that emphasizes a motivational, person-centered approach to brief cessation interventions. Recommendations for future tobacco cessation intervention trainings are presented. PMID:21986244

2012-01-01

Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination. We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis. PMID:22438633

Individual psychotherapy for schizophrenia: trends and developments in the wake of the recovery movement

2013-01-01

Although the role and relative prominence of psychotherapy in the treatment of schizophrenia has fluctuated over time, an analysis of the history of psychotherapy for schizophrenia, focusing on findings from the recovery movement, reveals recent trends including the emergence of the development of integrative psychotherapy approaches. The authors suggest that the recovery movement has revealed limitations in traditional approaches to psychotherapy, and has provided opportunities for integrative approaches to emerge as a mechanism for promoting recovery in persons with schizophrenia. Five approaches to integrative psychotherapy for persons with schizophrenia are presented, and a shared conceptual framework that allows these five approaches to be compatible with one another is proposed. The conceptual framework is consistent with theories of recovery and emphasizes interpersonal attachment, personal narrative, and metacognitive processes. Implications for future research on integrative psychotherapy are considered. PMID:23950665

The role of maternal communication patterns about interparental disputes in associations between interparental conflict and child psychological maladjustment.

Gomulak-Cavicchio, Beata M; Davies, Patrick T; Cummings, E Mark

2006-12-01

The present study examined the role of mothers' communication with children about interparental disputes in associations between interparental conflict and child psychological maladjustment in a sample of 227 children and their parents followed over a one-year span. Most of the time (i.e., 79.8%) mothers reported that they would communicate with their children following interparental disputes, with the vast majority of those communications containing relatively constructive depictions of interparental conflict. Post-conflict communications were not associated with children's adjustment above and beyond the impact of interparental conflict. However, maternal communications underscoring family cohesion and warmth, emphasizing remorse for engaging in the interparental disagreement, and denying the occurrence of the dispute each moderated associations between interparental conflict and child externalizing symptoms in distinct, complex ways. The findings in general suggest that not all positive communications have the beneficial impact on children that parents may have intended.

Rubus liebmannii is an endemic species from Mexico used in traditional medicine primarily to treat dysentery and cough. The in vitro activity against Giardia lamblia and Entamoeba histolytica that produces the ethanolic extract of the aerial parts of the plant led us to expand the pharmacological and phytochemical research of this species. Gastrointestinal disorders including amebiasis remain one of the health problems that need to be addressed and it is of interest to find alternatives that improve their treatment. Also, it is important to emphasize that R. liebmannii grows wild in the country and is not found in abundance; therefore, alternatives that avoid overexploitation of the natural resource are mandatory. Ongoing with the evaluation of the potentialities that R. liebmannii possesses for treating infectious gastrointestinal diseases, the aim of the present study was to evaluate the biological effects and the chemical composition of the micropropagated plant.

Numerous studies have reported the capacity of the lectin, concanavalin A, to agglutinate selected cell-types. The finding that cells transformed in culture, embryonic cells, and malignant cells are all agglutinated by this substance, may contribute to our understanding of the oncogenic process. The present study compared the response to concanavalin A of rat hepatocytes derived from livers of differing developmental and mitotic-status as well as those derived from malignant liver tumors (hepatomas). Fetal hepatocytes and hepatoma cells were highly susceptible to agglutination while hepatocytes from post-natal livers, whether dividing or quiescent, were not. Treatment with protease(s) did not make the interphase hepatocyte agglutinable. These data emphasize the importance of examining a wide variety of cells in attempting to understand the interaction of lectins on cell surfaces, and further, demonstrate the value of obtaining cells directly from tissue(s) during differing physiologic and pathologic states.

Effects of an intervention with teachers in the physical education context: A Self-Determination Theory approach

PubMed Central

2017-01-01

Framed within Self-Determination Theory, the purpose of the present study was to test the effects of a training program with physical education (PE) teachers. Participants were 21 high school PE teachers (experimental group, n = 10; control group, n = 11), and their 836 students, aged 12 to 16 years. Teachers in the experimental group received a training program consisting of strategies to support autonomy, competence, and relatedness need satisfaction. A repeated measures ANCOVA was carried out for each dependent variable. After the intervention, students in the experimental group significantly increased their scores on autonomy support, relatedness support, autonomy satisfaction, autonomous motivation, controlled motivation, and intention to be physically active, as compared to the control group. These findings emphasize the utility of a training program with PE teachers to promote the students’ psychological need satisfaction, and hence, self-determined motivation toward PE classes.

Everyday actions (e.g., riding a bike) can be described in ways that emphasize either the goals of the action by adapting a higher level identification (e.g., getting exercise) or the processes of the action by adapting a lower level identification (e.g., pedaling). In Studies 1 and 2, we demonstrate cultural differences in focusing on the process or goal of actions at the individual level: Americans are more likely than Japanese to focus on the goal (rather than the process) of actions. Study 3 recruited Chinese participants in addition to American and Japanese participants and found that cultural differences in action identification are partly explained by cultural differences in self-consistency. Study 4 further showed cultural differences at the collective level: American media presents more goal-oriented information and less process-oriented information than does Japanese media. These findings highlight the role of culture in shaping how people attend to different aspects of actions.

This research examined the dual function of gratitude for relationship maintenance in close relationships. In a longitudinal study among married couples, the authors tested the dyadic effects of gratitude over three time points for approximately 4 years following marriage. They found that feelings of gratitude toward a partner stem from the partner's relationship maintenance behaviors, partly because such behaviors create the perception of responsiveness to one's needs. In turn, gratitude motivates partners to engage in relationship maintenance. Hence, the present model emphasizes that gratitude between close partners (a) originates from partners' relationship maintenance behaviors and the perception of a partner's responsiveness and (b) promotes a partner's reciprocal maintenance behaviors. Thus, the authors' findings add credence to their model, in that gratitude contributes to a reciprocal process of relationship maintenance, whereby each partner's maintenance behaviors, perceptions of responsiveness, and feelings of gratitude feed back on and influence the other's behaviors, perceptions, and feelings.

Predicting and ranking potential invasive species present significant challenges to researchers and biosecurity agencies. Here we analyse a worldwide database of pest species assemblages to generate lists of the top 100 insect pests most likely to establish in the United States and each of its 48 contiguous states. For the United States as a whole, all of the top 100 pest species have already established. Individual states however tend to have many more 'gaps' with most states having at least 20 species absent from their top 100 list. For all but one state, every exotic pest species currently absent from a state's top 100 can be found elsewhere in the contiguous United States. We conclude that the immediate threat from known invasive insect pests is greater from within the United States than without. Our findings have potentially significant implications for biosecurity policy, emphasizing the need to consider biosecurity measures beyond established national border interventions.

γ-Aminobutyric acid receptors (GABA A Rs) are vital for controlling excitability in the brain. This is emphasized by the numerous neuropsychiatric disorders that result from receptor dysfunction. A critical component of most native GABA A Rs is the α subunit. Its transmembrane domain is the target for many modulators, including endogenous brain neurosteroids that impact anxiety, stress and depression, and for therapeutic drugs, such as general anesthetics. Understanding the basis for the modulation of GABA A R function requires high-resolution structures. Here we present the first atomic structures of a GABA A R chimera at 2.8-Å resolution, including those bound with potentiating and inhibitory neurosteroids. These structures define new allosteric binding sites for these modulators that are associated with the α-subunit transmembrane domain. Our findings will enable the exploitation of neurosteroids for therapeutic drug design to regulate GABA A Rs in neurological disorders.

Reis, Harry T; O'Keefe, Stephanie D; Lane, Richard D

Fun activities are commonly sought and highly desired yet their affective side has received little scrutiny. The present research investigated two features of fun in two daily diary studies and one laboratory experiment. First, we examined the affective state associated with fun experiences. Second, we investigated the social context of fun, considering whether shared fun is more enjoyable than solitary fun. Findings from these studies indicated that fun is associated with both high-activation and low-activation positive affects, and that it is enhanced when experienced with others (especially friends). However, social fun was associated with increases in high-activation but not low-activation positive affect, suggesting that social interaction emphasizes energizing affective experiences. We also found that loneliness moderated the latter effects, such that lonely individuals received a weaker boost from shared compared to solitary fun. These results add to what is known about the impact of social contexts on affective experience.

This paper presents the findings of a case study to achieve energy-efficient performance of conventional office buildings in Malaysia. Two multi-storey office buildings in Federal Territory of Malaysia have been selected. The aim is to study building energy saving potential then to highlight the appropriate measures that can be implemented. Data was collected using benchmarking method by comparing the measured consumption to other similar office buildings and a series of preliminary audit which involves interviews, a brief review of utility and operating data as well as a walkthrough in the buildings. Additionally, in order to get a better understanding of major energy consumption in the selected buildings, general audit have been conducted to collect more detailed information about building operation. In the end, this study emphasized low-cost and no-cost practice to achieve energy efficiency with significant results in some cases.

Cystic echinococcosis (CE) is a zoonotic disease; in places such as Turkey where livestock is common, it is an endemic health concern. The most commonly involved organ is the lungs in children. Pulmonary cysts can be asymptomatic; in some cases, they may rupture and become symptomatic. Ruptured lung hydatid cysts may often be confused with tuberculosis (Tbc) radiologically and clinically. . In this report, we present an 8-year-old female patient admitted with cough, fever, and sputum persisting since 2 weeks; her chest radiography and computed tomography (CT) findings initially indicated Tbc, but the follow-up surgery led to a diagnosis of ruptured lung CE. We want to emphasize that in children belonging to places where livestock is common, if respiratory symptoms are observed, CE and tuberculosis must be considered in the differential diagnosis, and the final diagnosis should be supported by other microbiological-serological tests.

Sensory systems are known to adapt their coding strategies to the statistics of their environment, but little is still known about the perceptual implications of such adjustments. We investigated how auditory spatial processing adapts to stimulus statistics by presenting human listeners and anesthetized ferrets with noise sequences in which interaural level differences (ILD) rapidly fluctuated according to a Gaussian distribution. The mean of the distribution biased the perceived laterality of a subsequent stimulus, whereas the distribution's variance changed the listeners' spatial sensitivity. The responses of neurons in the inferior colliculus changed in line with these perceptual phenomena. Their ILD preference adjusted to match the stimulus distribution mean, resulting in large shifts in rate-ILD functions, while their gain adapted to the stimulus variance, producing pronounced changes in neural sensitivity. Our findings suggest that processing of auditory space is geared toward emphasizing relative spatial differences rather than the accurate representation of absolute position.

Enhanced emotion-induced amnesia in borderline personality disorder

HURLEMANN, RENÉ; HAWELLEK, BARBARA; MAIER, WOLFGANG; DOLAN, RAYMOND J.

2009-01-01

Background Current biological concepts of borderline personality disorder (BPD) emphasize the interference of emotional hyperarousal and cognitive functions. A prototypical example is episodic memory. Pre-clinical investigations of emotion–episodic memory interactions have shown specific retrograde and anterograde episodic memory changes in response to emotional stimuli. These changes are amygdala dependent and vary as a function of emotional arousal and valence. Method To determine whether there is amygdala hyper-responsiveness to emotional stimuli as the underlying pathological substrate of cognitive dysfunction in BPD, 16 unmedicated female patients with BPD were tested on the behavioural indices of emotion-induced amnesia and hypermnesia established in 16 healthy controls. Results BPD patients displayed enhanced retrograde and anterograde amnesia in response to presentation of negative stimuli, while positive stimuli elicited no episodic memory-modulating effects. Conclusion These findings suggest that an amygdala hyper-responsiveness to negative stimuli may serve as a crucial aetiological contributor to emotion-induced cognitive dysfunction in BPD.

Subarachnoid hemorrhage (SAH) of spinal origin is uncommon in clinical practice, and spinal schwannomas associated with SAH are even more rarely reported. We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma. A retrospective chart review of the patient was performed. We describe a case of SAH due to spinal cord schwannoma. Our case highlights the importance of careful history taking and complete evaluation. We emphasize that spinal causes should always be ruled out in patients with angionegative SAH and that schwannoma should be considered in the differential diagnosis of SAH etiologies even though rare.

Expanding the mind's workspace: training and transfer effects with a complex working memory span task.

Chein, Jason M; Morrison, Alexandra B

2010-04-01

In the present study, a novel working memory (WM) training paradigm was used to test the malleability of WM capacity and to determine the extent to which the benefits of this training could be transferred to other cognitive skills. Training involved verbal and spatial versions of a complex WM span task designed to emphasize simultaneous storage and processing requirements. Participants who completed 4 weeks of WM training demonstrated significant improvements on measures of temporary memory. These WM training benefits generalized to performance on the Stroop task and, in a novel finding, promoted significant increases in reading comprehension. The results are discussed in relation to the hypothesis that WM training affects domain-general attention control mechanisms and can thereby elicit far-reaching cognitive benefits. Implications include the use of WM training as a general tool for enhancing important cognitive skills.

A familiarity disadvantage for remembering specific images of faces.

PubMed

Armann, Regine G M; Jenkins, Rob; Burton, A Mike

2016-04-01

Familiar faces are remembered better than unfamiliar faces. Furthermore, it is much easier to match images of familiar than unfamiliar faces. These findings could be accounted for by quantitative differences in the ease with which faces are encoded. However, it has been argued that there are also some qualitative differences in familiar and unfamiliar face processing. Unfamiliar faces are held to rely on superficial, pictorial representations, whereas familiar faces invoke more abstract representations. Here we present 2 studies that show, for 1 task, an advantage for unfamiliar faces. In recognition memory, viewers are better able to reject a new picture, if it depicts an unfamiliar face. This rare advantage for unfamiliar faces supports the notion that familiarity brings about some representational changes, and further emphasizes the idea that theoretical accounts of face processing should incorporate familiarity.

We present a design study of the TensorFlow Graph Visualizer, part of the TensorFlow machine intelligence platform. This tool helps users understand complex machine learning architectures by visualizing their underlying dataflow graphs. The tool works by applying a series of graph transformations that enable standard layout techniques to produce a legible interactive diagram. To declutter the graph, we decouple non-critical nodes from the layout. To provide an overview, we build a clustered graph using the hierarchical structure annotated in the source code. To support exploration of nested structure on demand, we perform edge bundling to enable stable and responsive cluster expansion. Finally, we detect and highlight repeated structures to emphasize a model's modular composition. To demonstrate the utility of the visualizer, we describe example usage scenarios and report user feedback. Overall, users find the visualizer useful for understanding, debugging, and sharing the structures of their models.

2016-12-01

Just as the Next Generation Science Standards (NGSSs) call for change in what students learn and how they are taught, teacher education programs must reconsider courses and curriculum in order to prepare teacher candidates to understand and implement new standards. In this study, we examine the development of prospective elementary teachers' practical knowledge of the NGSS in the context of a science methods course and innovative field experience. We present three themes related to how prospective teachers viewed and utilized the standards: (a) as a useful guide for planning and designing instruction, (b) as a benchmark for student and self-evaluation, and (c) as an achievable vision for teaching and learning. Our findings emphasize the importance of collaborative opportunities for repeated teaching of the same lessons, but question what is achievable in the context of a semester-long experience.

Diagnosis of blunt traumatic aortic injury 2007: still a nemesis.

PubMed

Mirvis, Stuart E; Shanmuganathan, K

2007-10-01

In recent years, the use of multidetector computed tomography (MDCT) for the diagnosis of acute thoracic injury in blunt trauma has expanded. MDCT has shown high accuracy for the diagnosis or exclusion of injury to the aorta and its primary branches, decreasing the need for thoracic angiography and allowing earlier treatment of this often rapidly fatal lesion. With increasing use of MDCT, more subtle injuries and variants of vascular anatomy are being recognized that create pitfalls in the diagnosis. Of perhaps more concern is the recognition that aortic injury can occur with little or no associated mediastinal hematoma, the principle chest radiographic finding indicating a need for further imaging. The importance of recognizing unusual sites of aortic injury, congenital variants of mediastinal anatomy, the precise extent of injury, and the anatomic pathology present as key factors in deciding among treatment options is emphasized.

On the line: worker democracy and the struggle over occupational health and safety.

Granzow, Kara; Theberge, Nancy

2009-01-01

In this article we present a qualitative analysis of worker involvement in a participatory project to improve occupational health and safety at a Canadian manufacturing site. Based on interviews with workers in the plant, we consider the manner and degree to which workers experienced meaningful participation in the intervention process and some of the main barriers to worker participation. Findings emphasize the importance of the social and political context in conditioning the dynamics of joint management labor ventures specifically in relation to health initiatives. Interviews revealed few instances in which workers felt included in the participatory initiative; most often they felt marginalized. In the absence of structural change in the plant, workers described the health initiative as seriously limited in its ability to render meaningful worker participation. These results extend beyond this analysis of a participatory workplace health initiative, offering insights into the dynamics of institutional participatory process, and into participatory research practice generally.

The challenges of early adolescence are intensified for girls of color who live in disadvantaged urban communities. One response to the needs of these girls comes from the Boys & Girls Clubs of America (BGCA), a youth development organization that has a long-standing presence in inner-city neighborhoods. A gender equity initiative designed to strengthen programming for minority girls at a BGCA affiliate in a major urban center was examined. Drawing on initial qualitative findings, a conceptual framework is presented for understanding the ways in which the clubs can affect urban early adolescent girls’ self-esteem. Several strategic choices confronting this initiative then are considered. The authors emphasize the creation of a “home place” that enables the development of self via organizational responsiveness to girls’ voices, strong bonds between girls and staff, adaptive peer friendship cliques, and the development of programs that fuse the interests of girls and adult staff.

Molecular electronics covers several distinctly different conducting architectures, including organic semiconductors and single-molecule junctions. The noncovalent interactions, abundant in the former, are also often found in the latter, i.e., the dimer junctions. In the present work, we draw the parallel between the two types of noncovalent molecular electronics for a range of π-conjugated heteroaromatic molecules. In silico modeling allows us to distill the factors that arise from the chemical nature of their building blocks and from their mutual arrangement. We find that the same compounds are consistently the worst and the best performers in the two types of electronic assemblies, emphasizing the universal imprint of the underlying chemistry of the molecular cores on their diverse charge transport characteristics. The interplay between molecular and intermolecular factors creates a spectrum of noncovalent conductive architectures, which can be manipulated using the design strategies based upon the established relationships between chemistry and transport.

This book was written for teachers and other scholars. An excerpt from Corgan's introduction gracefully places a new burden on the backs of those of us who fall into these categories. ‘…People of the nonscientific culture normally keep the records of civilization, for this group includes the historians, who control what posterity learns. Typically historians study just part of civilization and they emphasize the part they find most interesting: the nonscientific culture in which they are personally involved. … In studies of southern history, the individual scientific fields and science as a whole seem to suffer from systematic oversight. At a minimum they have not been overstudied. Yet science is deeply integrated into contemporary southern culture. … A dearth of contemporary scholarship should enhance the value of the present volume.’ Obviously, teachers and scholars should understand that there is now a tool available and ready to be used. Let's look at it.
