Intentions of formally qualified and unqualified teachers to transfer norms and values in home economics teaching

Historically, home economics (HE) in general, and the consumer education sections in particular, have been criticized for transferring norms and values of conservative elites to the masses. This is in stark contrast to contemporary theoretical views of a modern HE aimed at educating emancipated and critical citizens, and also to modern curricula that emphasize the consequences of consumption rather than dogma. A previous study has indicated that formally unqualified teachers see the transfer of consumption norms and values without support in the curriculum as an important objective of HE teaching, a practice that is questionable from a democratic perspective. This follow-up study investigates to what extent formally qualified HE teachers show intentions to transfer consumption norms and values without support in the curriculum to students, using content analysis of 201 survey responses from Swedish qualified HE teachers and comparing to data from a previously published study on formally unqualified teachers. It is concluded that the qualified teachers demonstrate intentions to transfer unsupported norms and values, though, to a lower degree than unqualified teachers. The results are interpreted by adopting a values education perspective on HE. This indicates that the observed emphasis on norms and values could be seen partly as a lack of a proficient professional metalanguage among the teachers, and partly as a consequence of the focus on developing a pre-defined moral of consumption in HE literature. The implications on how to develop HE teacher education to reduce norm and value transfer intentions are discussed based on the empirical findings and the theoretical framework. (Less)
Framing of Majority and Minority Source Information in Persuasion When and How "Consensus Implies Correctness"

Information about source consensus may either create expectancies of message validity that bias subsequent processing, or may determine the amount of message processing. The authors propose that which of the two effects occurs depends on the framing of consensus information. Undergraduates (N = 242) read strong, ambiguous, or weak arguments on an issue; the source was framed as either knowledgeable or similar to participants; source consensus was either low (minority) or high (majority). Dependent variables were the favorability of cognitive responses and postmessage attitudes. As predicted, knowledge framing caused consensus-based assimilation for ambiguous arguments, and contrast for both strong and weak arguments, whereas similarity framing caused extensive processing of minority arguments, but uncritical acceptance of majority arguments.
Transitioning from egg to embryo: Triggers and mechanisms of egg activation

The transition from mature oocyte to developing embryo requires a coordinated series of events, collectively known as egg activation. Egg activation includes changes to egg coverings to prevent polyspermy, release of oocyte meiotic arrest, generation of haploid female and male pronuclei, changes in maternal mRNAs and protein populations, and cytoskeletal rearrangements. In many animals, egg activation is triggered by fertilization, which increases intracellular calcium within the oocyte and thereby regulates molecular events of egg activation. In other animals, fertilization‐independent external signals, including mechanical stimulation of eggs and/or changes in ionic milieu, trigger activation. Recent studies have clarified the upstream portion of pathways leading to eggshell changes and cell cycle resumption and have identified activation‐induced changes in maternal mRNA and protein profiles that can identify molecular players in the downstream events of egg activation. We review signals that trigger activation and how they link to subsequent molecular events of egg activation. Developmental Dynamics 237:527–544, 2008. © 2008 Wiley‐Liss, Inc.
Transthyretin Internalization by Sensory Neurons Is Megalin Mediated and Necessary for Its Neuritogenic Activity

Mutated transthyretin (TTR) causes familial amyloid polyneuropathy, a neurodegenerative disorder characterized by TTR deposition in the peripheral nervous system (PNS). The origin/reason for TTR deposition in the nerve is unknown. Here we demonstrate that both endogenous mouse TTR and TTR injected intravenously have access to the mouse sciatic nerve. We previously determined that in the absence of TTR, both neurite outgrowth in vitro and nerve regeneration in vivo were impaired. Reinforcing this finding, we now show that local TTR delivery to the crushed sciatic nerve rescues the regeneration phenotype of TTR knock-out (KO) mice. As the absence of TTR was unrelated to neuronal survival, we further evaluated the Schwann cell and inflammatory response to injury, as well as axonal retrograde transport, in the presence/absence of TTR. Only retrograde transport was impaired in TTR KO mice which, in addition to the neurite outgrowth impairment, might account for the decreased regeneration in this strain. Moreover, we show that in vitro, in dorsal root ganglia neurons, clathrin-dependent megalin-mediated TTR internalization is needed for TTR neuritogenic activity. Supporting this observation, we demonstrate that in vivo, decreased levels of megalin lead to decreased nerve regeneration and that megalin's action as a regeneration enhancer is dependent on TTR. In conclusion, our work unravels the mechanism of TTR action during nerve regeneration. Additionally, TTR presence in the nerve, as is here shown, may underlie its preferential deposition in the PNS of familial amyloid polyneuropathy patients.
Solving large size instances of the RWA problem using graph partitioning

In this paper, we propose a new heuristic to solve large instances of the Routing and Wavelength Assignment problem (RWA). First, the initial instance is split into several smaller instances that are optimally solved using the ILP formulation of the problem. This decomposition is obtained by partitioning the set of edges of the network and is such that the different instances can be solved independently. Then the local solutions are combined in order to obtain a feasible solution of the initial instance. Herein the method is used to solve the Static Lightpath Establishment problem (SLE), but can be easily applied to any RWA problem. We validate the proposed method on a real network and on large random instances. The obtained results are compared with the optimal ones or with those of a sequential algorithm.
Romance in Cyberspace: Understanding Online Attraction

While many people think that electronic relating promotes emotionally disconnected or superficially erotic contacts, the structure and process of online relating can facilitate positive interpersonal connections, including the healthy development of romantic relationships. Computer mediated relating (CMR) reduces the role that physical attributes play in the development of attraction, and enhances other factors such as propinquity, rapport, similarity, and mutual self-disclosure, thus promoting erotic connections that stem from emotional intimacy rather than lustful attraction. The Net is a model of intimate yet separate relating. It allows adult (and teen) men and women more freedom to deviate from typically constraining gender roles that are often automatically activated in face-to-face interactions. Online relating can lead to destructive results when people act on or compulsively overindulge in a speeded up, eroticized pseudo-intimacy. Clinicians can help their clients make positive use of online rela.
Predictors of hypertension control in Turkey: the MELEN study.

BACKGROUND Hypertension is one of the most common causes of atherosclerosis, morbidity and mortality in adults. A total of 11 million hypertensive patients were estimated in Turkey. AIM The aim of this study was to investigate the prevalence, awareness and control of hypertension in Duzce and compare the current data with the literature. MATERIALS AND METHODS The visits were carried out in May and June, 2010 in Yigilca town health centre on 2298 participants (1471 female, 827 male with a mean age of 50). Data were obtained by a simple form, physical examination and sampling of blood. Hypertension was defined as a blood pressure 140 mmHg and/or 90 mmHg, and/or use of antihypertensive medication. The data of patients under control were compared with the patients who were not under control. RESULTS Hypertension was detected in 964 participants. General prevalence was 42%. Hypertension awareness ratio was 70%, use of antihypertensive medication was 39% and the ratio of patients under control was 28%. Antihypertensive drug use, age and awareness were lower in the uncontrolled group. Logistic regression analysis revealed that only antihypertensive drug use and BMI < 30 were the independent predictors of hypertension under control [Odd's ratio (OR) = 3.43; 95% confidence interval (CI) = 2.54-4.64, p < 0.001 and OR = 1.69; 95% CI = 1.23- 2.32, p = 0.01; respectively]. CONCLUSIONS Hypertension is one of the most important public health problems in Turkey. According to the literature data the awareness of hypertension was increased significantly in the last five years. On the other hand, control ratio was increased very little compared with the previous studies.
Biographical Precursors of Musical Excellence: An Interview Study

Forty-two students (aged 10-18) from a special school for musically gifted children were interviewed. Twenty of their parents were also interviewed. The interviews provided exhaustive information about the students' musical life prior to enrolling at the school. It was found that most students did not show any particular signs of early musical promise, and that most parents took an active role in supervising and encouraging the child's progress. The more highly accomplished students tended to come from less musically active families, and tended to have had fewer early lessons than the less highly accomplished students. The most able students had not devoted more time to practice than the others, but their practice time was more evenly distributed between a number of instruments. Results are discussed in terms of social and motivational influences on learning and development.
Idiopathic transverse myelitis

Transverse myelitis is a focal disorder of the spinal cord in which an immune-mediated process results in neural injury. In this large retrospective study, we compare patients who received one of four treatments to identify the most effective therapies. We identified subsets of patients who received clinical benefit from plasma exchange or cyclophosphamide being included in their treatment regimen.
The Cost of Science Performance Assessments in Large-Scale Testing Programs

Estimates of the costs of including hands-on measures of science skills in large-scale assessment programs are drawn from a field trial involving more than 2,000 fifth- and sixth-grade students. These estimates include the resources needed to develop, administer, and score the tasks. They suggest that performance measures are far more expensive than typical multiple-choice tests for an equal amount of testing time, and the cost increases even further for an equally reliable score on an individual student. Because of the complexities of equipment and materials, hands-on measures in science are about three times more expensive than open-ended writing assessments. Alternative approaches to development and administration (such as using less expensive equipment and having the tasks administered by classroom teachers rather than trained Exercise Administrators) could reduce costs by up to 50%, but these practices may reduce the quality of the data obtained. However, including performance assessments in a state’s testing program may have many positive effects, including fostering standards-based educational reform and encouraging more effective teaching methods. The challenge is to determine whether these potential benefits actually exist and if they do, how they can be realized within the budget constraints of most testing programs.
Enhancement of Biodiesel Production from Marine Alga, Scenedesmus sp. through In Situ Transesterification Process Associated with Acidic Catalyst

The aim of this study was to increase the yield of biodiesel produced by Scenedesmus sp. through in situ transesterification by optimizing various process parameters. Based on the orthogonal matrix analysis for the acidic catalyst, the effects of the factors decreased in the order of reaction temperature (47.5%) > solvent quantity (26.7%) > reaction time (17.5%) > catalyst amount (8.3%). Based on a Taguchi analysis, the effects of the factors decreased in the order of solvent ratio (34.36%) > catalyst (28.62%) > time (19.72%) > temperature (17.32%). The overall biodiesel production appeared to be better using NaOH as an alkaline catalyst rather than using H2SO4 in an acidic process, at 55.07 ± 2.18% (based on lipid weight) versus 48.41 ± 0.21%. However, in considering the purified biodiesel, it was found that the acidic catalyst was approximately 2.5 times more efficient than the alkaline catalyst under the following optimal conditions: temperature of 70°C (level 2), reaction time of 10 hrs (level 2), catalyst amount of 5% (level 3), and biomass to solvent ratio of 1 : 15 (level 2), respectively. These results clearly demonstrated that the acidic solvent, which combined oil extraction with in situ transesterification, was an effective catalyst for the production of high-quantity, high-quality biodiesel from a Scenedesmus sp.
Cellular Localization of Gene Expression for Progranulin

Granulins, also called epithelins, are 6-kD peptides with growth modulatory effects on a variety of cells. The granulin/epithelin precursor supports tumorigenesis in appropriate cell models and is the only growth factor able to overcome the cell cycle block that occurs in murine fibroblasts after deletion of a functional IGF-1 receptor. However, little is known of the role of granulin/epithelin gene products in vivo. To understand the physiological role of granulins it is essential to know the cell types and conditions in which it is expressed. We examined granulin/epithelin gene expression in adult rodents by in situ hybridization. The granulin/epithelin precursor is constitutively expressed in a number of epithelia, particularly in the skin, GI tract, and reproductive system. Other epithelia express the gene less strongly. Progranulin is expressed in immune cells in vivo and in specific neurons in the brain, including Purkinje cells, pyramidal cells of the hippocampus, and some cerebral cortical neurons. Little expression was detected in muscle cell, connective tissue, or endothelium. Cumulatively, these results define the basal gene expression of a new growth factor system and suggest that the progranulin/epithelin gene is multifunctional, with important constitutive roles in epithelial homeostasis, reproductive, immunological, and neuronal function.
Genetic and physical map of the 2,4-dichlorophenoxyacetic acid-degradative plasmid pJP4

Plasmid pJP4 is an 80-kilobase, IncP1, broad-host-range conjugative plasmid of Alcaligenes eutrophus encoding resistance to mercuric chloride and phenyl mercury acetate and degradation of 2,4-dichlorophenoxyacetic acid, 2-methyl-4-chlorophenoxyacetic acid, and 3-chlorobenzoate. By the use of cloning, transposon mutagenesis, and restriction endonuclease analysis, a biophysical and genetic map of pJP4 was generated.
The Chemical Composition and the Content of Volatile Oil: Potential Factors that Can Contribute to the Oxidative Stability of Nigella sativa L. Crude Oil

ABSTRACT The crude oil of Nigella sativa L. (Black cumin) has well-known nutraceutical and pharmaceutical properties. The oil is prone to rapid oxidative deterioration because of its high content of poly-unsaturated fatty acids. In the current investigation, different cold-pressed crude oils of N. sativa were examined for their composition of fatty acids and oxidative stability. The data obtained were correlated with the chemical composition and content of volatile oils, which correspond to each crude oil. Results indicated that different crude oils have the same fatty acid composition, and linoleic acid was the major constituent (60.0–61.7%). Though, the oxidative stability index of the crude oils was different ranging from 2.5 hr to 26.9 hr, as revealed by the Rancimate test at 100°C and airflow rate of 20 ml/min. The results showed that there is a straightforward correlation between the volatile oil content and the oxidative stability of the corresponding parent crude oil. In addition, high γ-terpinene content in the constitution of volatile oil can also be another contributing factor for enhancing the oxidative stability of the crude oil. The data presented here draw attention to some important factors that may guide the nutraceutical and food supplement processors in their screening for the highest quality of Nigella crude oils with maximum health benefits.
Juxtaparanodal clustering of Shaker-like K+ channels in myelinated axons depends on Caspr2 and TAG-1

In myelinated axons, K+ channels are concealed under the myelin sheath in the juxtaparanodal region, where they are associated with Caspr2, a member of the neurexin superfamily. Deletion of Caspr2 in mice by gene targeting revealed that it is required to maintain K+ channels at this location. Furthermore, we show that the localization of Caspr2 and clustering of K+ channels at the juxtaparanodal region depends on the presence of TAG-1, an immunoglobulin-like cell adhesion molecule that binds Caspr2. These results demonstrate that Caspr2 and TAG-1 form a scaffold that is necessary to maintain K+ channels at the juxtaparanodal region, suggesting that axon–glia interactions mediated by these proteins allow myelinating glial cells to organize ion channels in the underlying axonal membrane.
Word class influence on word association test results1

The aim of this article is to investigate the influence of word class on word association test results in both the L1 and L2. The data clearly suggest that word class type affects test results: nouns elicit a higher proportion of paradigmatic responses than verbs and adjectives. The influence of word class on test results is discussed in terms of the acquisition and semantic organisation of nouns, verbs and adjectives. However, results also show a surprising majority of syntagmatic responses in the L1 test. These results lead to a critical discussion of the concept of the syntagmatic–paradigmatic shift, which in the light of the test results in this study is seriously challenged. Theoretical and pedagogical implications for lexical network structure are discussed. Malet med denne artikel er at undersoge ordklassers betydning for testresultater i ordassociationstests pa L1 og L2. Data viser tydeligt, at ordklasse i hoj grad pavirker testresultaterne: substantiver resulterer i en storre andel paradigmatiske respons end verber og adjektiver. Ordklassernes pavirkning af testresultater diskuteres i forhold til ordtilegnelse, samt maden substantiver, verber og adjektiver er organiseret semantisk i det mentale leksikon. Resultaterne viser en uventet overvaegt af syntagmatiske respons i L1-testen. Dette leder til en kritisk diskussion af begrebet det syntagmatisk–paradigmatiske skift, som bliver afgorende udfordret af testresultaterne i denne undersogelse. Teoretiske og paedagogiske konsekvenser af det leksikalske netvaerks struktur diskuteres.
13. Sacroiliac Joint Pain

The sacroiliac joint accounts for approximately 16% to 30% of cases of chronic mechanical low back pain. Pain originating in the sacroiliac joint is predominantly perceived in the gluteal region, although pain is often referred into the lower and upper lumbar region, groin, abdomen, and/ or lower limb(s). Because sacroiliac joint pain is difficult to distinguish from other forms of low back pain based on history, different provocative maneuvers have been advocated. Individually, they have weak predictive value, but combined batteries of tests can help ascertain a diagnosis. Radiological imaging is important to exclude “red flags” but contributes little in the diagnosis. Diagnostic blocks are the diagnostic gold standard but must be interpreted with caution, because false‐positive as well as false‐negative results occur frequently. Treatment of sacroiliac joint pain is best performed in the context of a multidisciplinary approach. Conservative treatments address the underlying causes (posture and gait disturbances) and consist of exercise therapy and manipulation. Intra‐articular sacroiliac joint infiltrations with local anesthetic and corticosteroids hold the highest evidence rating (1 B+). If the latter fail or produce only short‐term effects, cooled radiofrequency treatment of the lateral branches of S1 to S3 (S4) is recommended (2 B+) if available. When this procedure cannot be used, (pulsed) radiofrequency procedures targeted at L5 dorsal ramus and lateral branches of S1 to S3 may be considered (2 C+).
SkipIndex : Towards a Scalable Peer-to-Peer Index Service for High Dimensional Data

Indexing of high-dimensional data is essential for building applications such as multimedia retrieval, data mining, and spatial databases. Traditional index structures rely on centralized processing. This approach does not scale with the rapidly increasing amount of application data available on massively distributed systems like the Internet. In this paper, we propose a distributed high-dimensional index structure based on peer-to-peer overlay routing. A new routing scheme is used to lookup data keys in the distributed index, which guarantees logarithmic lookup and maintenance cost, even in the face of skewed datasets. We propose a novel nearest neighbor (NN) query scheme that can substantially reduce search cost by sacrificing a small amount of precision. We propose a load-balancing mechanism that partitions the high dimensional search space in a balanced manner. We then analyze the performance of our proposed using a variety of metrics with simulation as well as a functional PlanetLab implementation.
Network Studies of Social Influence

Network analysts interested in social influence examine the social foundations for influence—the social relations that provide a basis for the alteration of an attitude or behavior by one network actor in response to another. This article contrasts two empirical accounts of social influence (structural cohesion and equivalence) and describes the social processes (e.g., identification, competition, and authority) presumed to undergird them. It then reviews mathematical models of influence processes involving networks and related statistical models used in data analysis. Particular attention is given to the “network effects” model. A number of empirical studies of social influence are reviewed. The article concludes by identifying several problems of specification, research design, and measurement and suggesting some research that would help to resolve these problems.
