Kinds of Feel Selected AbstractsHow Do Mothers Feel About Their Very Low Birth Weight Infants?INFANT MENTAL HEALTH JOURNAL, Issue 2 2006Development of a New Measure The early relationship between a mother and her very low birth weight (VLBW; <1.5 kg) infant may be difficult to evaluate. Therefore, we aimed to develop a useful and practical method to describe a mother's early relationship with her VLBW infant. Mothers (mean age=27 years, 46% married) of 119 singleton VLBW infants (mean BW=1,056 g, mean GA=28 weeks) admitted to the neonatal ICU at Rainbow Babies and Children's Hospital completed a novel questionnaire regarding their feelings about their infant at 3 weeks' postnatal age, and at 35 weeks', 40 weeks' (term), and 4 months' postmenstrual ages. Factor analysis of initial interview data was used to construct subscales to measure unique domains hypothesized to underpin the beginning maternal,infant relationship. Three subscales were identified: (a) The Worry subscale focuses on the mother's concerns about her infant's current medical condition and future development, (b) the Enjoyment subscale examines the mother's positive feelings about and responsiveness to her infant, and (c) the Separation Anxiety subscale examines the mother's mental anxiety about being physically separated from her infant. Statistical and clinical validation of the subscales produced positive supporting evidence that the subscales are a meaningful measure of the mother,infant relationship. We have developed a unique and practical measure for describing the early mother,VLBW infant relationship.

[source] Teaching Treaties as (Un)Usual Narratives: Disrupting the Curricular CommonsenseCURRICULUM INQUIRY, Issue 5 2008JENNIFER A. TUPPER This article examines the importance of treaty education for students living in a province entirely ceded through treaty. Specifically, we ask and attempt to answer the questions "Why teach treaties?" and "What is the effect of teaching treaties?" We build on research that explores teachers' use of a treaty resource kit, commissioned by the Office of the Treaty Commissioner in Saskatchewan. Working with six classrooms representing a mix of rural, urban and First Nations settings, the research attempts to make sense of what students understand, know and feel about treaties, about First Nations peoples and about the relationships between First Nations and non,First Nations peoples in Saskatchewan. It is revealing that initially students are unable to make sense of their province through the lens of treaty given the commonsense story of settlement they learn through mandated curricula. We offer a critique of the curricular approach in Saskatchewan which separates social studies, history and native studies into discrete courses. Drawing on critical race theory, particularly Joyce King's notion of "dysconscious" racism, we deconstruct curriculum and its role in maintaining dominance and privilege. We use the term (un)usual narrative to describe the potential of treaty education to disrupt the commonsense. (Un)usual narratives operate as both productive and interrogative, helping students to see "new" stories, and make "new" sense of their province through the lens of treaty. [source] A Multicenter, 47-Month Study of Safety and Efficacy of Calcium Hydroxylapatite for Soft Tissue Augmentation of Nasolabial Folds and Other Areas of the FaceDERMATOLOGIC SURGERY, Issue 2007NEIL S. SADICK MD OBJECTIVES Each soft tissue filler product has its own unique profile in terms of adverse events. In this large-scale study, we investigated the safety profile of Radiesse, an injectable calcium hydroxylapatite (CaHA) implant, in treatment of nasolabial folds and other areas of the face. We also investigated the efficacy in a subset of the larger patient group. METHODS After obtaining informed consent from the subjects, researchers injected CaHA at two treatment centers into 113 patients (100 women and 13 men, ranging in age from 26 to 78 years) for a variety of facial aesthetic applications over a period of 47 months. Seventy-five patients had a single injection session; 38 had multiple sessions. Most patients (102) received 1.0 mL of CaHA per session; 12 received 2.0 mL per session. Typically, CaHA was administered with a 27-gauge 0.5- or 1 1/4-in. needle. RESULTS Safety. Of 113 patients, only 7 reported minor adverse events that were short-term and resolved within 1 month: transient ecchymosis (3), nongranulatomous submucosal nodules of the lip (2), and inflammation and edema (2). Efficacy. Efficacy ratings were performed for a subset of patients (n=41). On a scale of 1 to 5 (1=unsatisfactory; 5=excellent), the mean patient evaluation score for look and feel of the implant was 4.6; the mean physician scores for the look and feel of the implant were 4.5 and 4.6, respectively. During the 6-month follow-up visit, patients' mean ratings of the look and feel of the implant were 4.8 and 4.9, respectively. The physician's mean ratings for the look and feel of the implant were 4.5 and 4.9, respectively. CONCLUSIONS In our study, CaHA performed well, with a favorable safety profile, high patient satisfaction (90% of patients reported very good or excellent results), and good durability. We are especially pleased with the low incidence of adverse events coupled with the favorable responses from the patients themselves due to longevity of correction. [source] A Review of the Biologic Effects, Clinical Efficacy, and Safety of Silicone Elastomer Sheeting for Hypertrophic and Keloid Scar Treatment and ManagementDERMATOLOGIC SURGERY, Issue 11 2007BRIAN BERMAN MD Silicone elastomer sheeting is a medical device used to prevent the development of and improve the appearance and feel of hypertrophic and keloid scars. The precise mechanism of action of silicone elastomer sheeting has not been defined, but clinical trials report that this device is safe and effective for the treatment and prevention of hypertrophic and keloid scars if worn over the scar for 12 to 24 hours per day for at least 2 to 3 months. Some of the silicone elastomer sheeting products currently on the market are durable and adhere well to the skin. These products are an attractive treatment option because of their ease of use and low risk of adverse effects compared to other treatments, such as surgical excision, intralesional corticosteroid injections, pressure therapy, radiation, laser treatment, and cryotherapy. Additional controlled clinical trials with large patient populations may provide further evidence for the efficacy of silicone elastomer sheeting in the treatment and prevention of hypertrophic and keloid scars. The purpose of this article is to review the literature on silicone elastomer sheeting products and to discuss their clinical application in the treatment and prevention of hypertrophic and keloid scars. [source] Highly Purified 1000-cSt Silicone Oil for Treatment of Human Immunodeficiency Virus-Associated Facial Lipoatrophy: An Open Pilot TrialDERMATOLOGIC SURGERY, Issue 10 2004Derek H. Jones MD Background. Among human immunodeficiency virus-infected individuals, facial lipoatrophy has become epidemic. Those affected are stigmatized, leading to psychological distress, social and career impediments, and impaired compliance to human immunodeficiency virus medications. Temporary treatment options are limited by excessive cost, necessity of frequent treatments, and lack of a natural look or feel beneath the skin. Affected patients require more persistent, affordable, safe, and effective treatment options. Objective. The objective was to evaluate the safety and efficacy of highly purified 1000-cSt silicone oil injected by microdroplet serial puncture technique for the treatment of human immunodeficiency virus-associated lipoatrophy. Methods. Data on 77 patients with a complete correction were analyzed to determine the number of treatments, amount of silicone, and time required to reach complete correction, relative to initial severity. Results. The volume of silicone, number of treatments, and time required to reach a complete correction were directly related to initial severity of lipoatrophy (p < 0.0001). Supple, even facial contours were routinely restored, with all patients tolerating treatments well. No adverse events were noted. Conclusion. In this pilot trial, we have demonstrated that highly purified 1000-cSt silicone oil is a safe and effective treatment option for human immunodeficiency virus facial lipoatrophy. Longer-term safety and efficacy in human immunodeficiency virus patients remain to be proven. [source] The art and science of oral examinationDERMATOLOGIC THERAPY, Issue 3 2010Rania Agha ABSTRACT Performing an accurate oral examination is an integral part of a complete dermatological evaluation. As dermatologists, we are frequently asked to assess and treat numerous oral pathologies, which include, but are not limited to, normal variants, infections, ulcers, granulomas, lymphomas, as well as primary and metastatic tumors of the mouth and lips. The oral mucosa can be the window through which one can see and make numerous systemic diagnoses. Some clinicians are apprehensive about performing this evaluation, or feel that this examination is outside of their realm of expertise. These concerns may reflect limited exposure and education during training. Therefore, this article aimed to educate the readers on how to complete an oral examination, demonstrate normal variants, and highlight potential pitfalls and limitations of performing oral biopsies.

[source] SPACES OF DIZZINESS AND DREAD: NAVIGATING ACROPHOBIAGEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 4 2007Gavin J. Andrews ABSTRACT As part of emerging disciplinary interests in well-being and emotions, geographers have recently begun to pay attention to common but often neglected psychological conditions that have the potential to impact considerably upon individuals and their daily lives. Specifically extending the scope of geographical inquiry on phobias, this paper considers acrophobia (known as being scared of heights). Through interviews with ten sufferers, the spatial character and intensity of the condition is articulated. The findings tell us that underpinning acrophobia is mathematical height: the vertical elevation from the lowest possible resting point of the body to the point at which the symptoms of acrophobia occur. This point is however - even for each individual - highly variable, context dependant and, in terms of explanatory potential, does not convey personal experiences. Instead, the idea of ,encounter spaces' provides far greater elaboration. Created by sufferers ,dysfunctional' spatial perceptions, these are the occupied spaces of mixed emotional and physical responses (such as fear and rapid breathing) and reactionary practices that are tactical yet somewhat involuntary in nature (such as gripping tighter or getting lower). Depending on the particular circumstances, sufferers might choose to, feel forced to, or might inadvertently enter encounter spaces. Their impacts also extend beyond immediate effects to sufferers' longer term lives and well-being. This might be negatively impacted, for example, through cumulative encounters, worrying about potential encounters or missing out on life events. At this level, reactionary practices - again which are tactical yet somewhat involuntary - are often employed in order to avoid height. Ultimately, the overall impact of acrophobia on an individual depends on a number of factors including the severity of their condition, the attitudes of the people they associate with, their job, lifestyle and the environments which they have to, or would like to, frequent. Consequently, while some sufferers cope with ease, others constantly navigate the altitude of their lives. [source] FEELING IS BELIEVING, OR LANDSCAPE AS A WAY OF BEING IN THE WORLDGEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 3 2007Edmunds Valdem, rs Bunk ABSTRACT. This article is work-in-progress, an orientation of thought towards possibilities for individual human beings to diminish the distance between outer and inner landscapes imposed by cultural norms and happenstances such as exile. The dominance of visual landscapes and visual perceptions is seen as a pivotal problem, to be solved by the engagement of all the senses in landscape discourse and formation. All the senses are engaged in earliest childhood, as they have been in ,primitive' societies. While returning to either a state of childhood or primitivism is an impossible dream, it is possible to edge closer to human nature by engaging and honing all the senses, especially the ,earth-bound senses' of feel, smell and taste. Cultivating those senses and developing discourse about them, and incorporating them into landscape formation and enjoyment, is much more difficult than having a discourse about sight and hearing, for which there is a rich and well-developed symbolic language and which can be shared through various types of media. The way towards a deeper discourse about the earth-bound senses, and the way out of the tyranny of the visual, is to be found in stories, as several thinkers suggest. The story told is autobiographical and literary , a mode of geographic writing that I developed in a 2004 book (Bunk,e 2004a), in which the complex dilemmas of home and road were explored. This article shows how in the early 1970s I defined the individual's landscape as ,a unity in one's surroundings perceived through all the senses', with imagination as the key human faculty. And I tell the story of how through complex circumstances, a visually and emotionally repugnant landscape became emotionally and intellectually attractive, with a scent, not a picture or image causing the initial attraction. The external and internal landscapes are thus unified, resulting in a sense of timelessness and placelessness of deep existential significance for the person. [source] Art As Religious Commitment: Kafka's Debt to Kierkegaardian Ideas and their Impact on his Late StoriesGERMAN LIFE AND LETTERS, Issue 4 2000Leena Eilttä Although Kafka's reception of Kierkegaardian ideas has received much critical attention the critics have so far paid little heed to similarities between Kierke-gaard's religious and Kafka's aesthetic views. My intention in the following is to show that in spite of Kafka's critical remarks on his philosophy, Kierkegaard's definition of a religious person influenced his description of the artist's existence in Erstes Leid (1922), Ein Hungerkünstler (1922) and Josefine, die Sängerin oder das Volk der Mäuse (1924). In these stories Kafka turns Kierkegaard's ideas about spiritual inwardness and passionate attitude towards religious life into artistic inwardness and passionate attitude towards art. He also describes how devotion that these artists feel towards their art leads to their solitude and how their lives reflect suffering, doubt and despair which is similar to Kierkegaard's description of religious suffering. Kafka's critical remarks on Kierkegaard's philosophy should therefore be understood as a clear rejection of Kierkegaard's Protestant theology, although these same ideas gave him inspiration to formulate his views on the artist's existence. [source] Effectiveness of Supportive Educative Learning programme on the level of strain experienced by caregivers of stroke patients in ThailandHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 1 2010R. Oupra RN MSc MNS PhD Abstract In Thailand, the crude death rate from stroke is 10.9/100 000 population and increasing. Unlike Western countries where community rehabilitation programmes have been established to provide services following the acute stage of stroke recovery, there is no stroke rehabilitation team in the community in Thailand. Therefore, family caregivers are the primary source for ongoing care and support. While family members accompany patients during their hospitalisation, they receive little information about how to assist their relatives, and as a result feel inadequately trained, poorly informed and dissatisfied with the support that is available after discharge. Family caregivers report that they suffer both physically and psychologically and find themselves overwhelmed with strain, experiencing burden and exhaustion. This study aimed to develop and implement a nurse-led Supportive Educative Learning programme for family caregivers (SELF) of stroke survivors in Thailand and to evaluate the effect of the SELF programme on family caregiver's strain and quality of life. This was a non-randomised comparative study with concurrent controls, using a two-group pre-test and post-test design. A total of 140 stroke survivors and 140 family caregivers were recruited; 70 patients/caregiver pair in each group. Caregivers of patients admitted to the intervention hospital following an acute stroke received the intervention, while caregivers of patients admitted to the comparison hospital received the usual care provided at the hospital. The data were collected prior to discharge of the patients and after 3 months. The family caregivers in the intervention group had a significantly better quality of life than the comparison group (GHQ-28 at discharge t = 2.82, d.f. = 138, P = 0.006; and at 3 months t = 6.80, d.f. = 135, P < 0.001) and they also reported less strain (Caregiver Strain Index at discharge t = 6.73, d.f. = 138, P < 0.001; and at 3 months t = 7.67, d.f. = 135, P < 0.001). This research demonstrated that providing education and support to the family caregiver of stroke survivors can reduce caregiver strain and enhance their quality of life. [source] Quality of life in patients with primary biliary cirrhosisHEPATOLOGY, Issue 2 2004Renée Eugénie Poupon The impact of primary biliary cirrhosis (PBC) on health-related quality of life (HRQOL) is poorly documented. We assessed quality of life in a group of 276 unselected patients with PBC using the Nottingham Health Profile (NHP). This is a generic scale that assesses six major areas commonly associated with HRQOL. Data were compared with those of a sex- and age-matched control group. The associations between NHP scores and the severity of PBC were tested. Patients (86% women) had a median age of 62 years (range 33,87). Most patients were treated with UDCA. PBC patients showed a strong statistically significant difference in energy compared to controls (respectively, 40.6 vs. 22.9, P < .0001) and had worse scores for emotional reactions (22.2 vs. 16.1, P < .005). No other differences were observed. No associations of the dimension subscores were found with biochemical liver tests, histological stages, or duration of the disease. Among the signs or symptoms, fatigue was the finding most often associated with the dimension subscores. In conclusion, patients with PBC feel that their overall quality of life is worse than that of the control population. This difference is mainly due to the decrease in the subscores of energy and emotional reactions, both associated with fatigue. These effects must be taken into account by clinicians when treating these patients, as they constitute the clinical outcomes that have the most impact on patients' lifestyle and adherence to treatment.

Tran Abstract This Progress Report provides a brief overview of current research activities in the field of one-dimensional (1D) conducting polymer nanostructures. The synthesis, properties, and applications of these materials are outlined with a strong emphasis on recent literature examples. Chemical methods that can produce 1D nanostructures in bulk quantities are discussed in the context of two different strategies: 1) procedures that rely on a nanoscale template or additive not inherent to the polymer and 2) those that do not. The different sub-classifications of these two strategies are delineated and the virtues and vices of each area are discussed. Following this discussion is an outline of the properties and applications of 1D conducting polymer nanostructures. This section focuses on applications in which nanostructured conducting polymers are clearly advantageous over their conventional counterparts. We conclude with our perspective on the main challenges and future research directions for this new class of nanomaterials. This Progress Report is not intended as a comprehensive review of the field, but rather a summary of select contributions that we feel will provide the reader with a strong basis for further investigation into this fast emerging field. [source] Ultrathin Nanowires,A Materials Chemistry Perspective,ADVANCED MATERIALS, Issue 9 2009Ludovico Cademartiri Abstract The recent years have seen an explosive interest in one-dimensional nanostructures1, as testified by the number of citations this field has accrued; as customary, its blossoming was enabled by chemical breakthroughs that allowed the reproducible and affordable synthesis of such structures.2, 3 The limitations of those syntheses was in the diameter of the nanowires that it could produce (hardly,<,10,nm), and in the use of expensive and low-yield techniques, such as chemical vapor deposition (CVD). This paper attempts to summarize the very recent chemical breakthroughs that have allowed the production of ultrathin nanowires, often in solution, and often in gram-scale quantities. By no means is this a comprehensive coverage of the field, which can in part be found in other excellent reviews1, 2, 4,6 but a selection of those contributions that we feel would most help put this emerging field in perspective. We will review the various synthetic strategies, their pros and cons, and we will give our best guesses as to the future directions of the field and what we can expect from it. [source] Copper and calcium uptake in colored hairINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 2 2010K. E. Smart J. Cosmet. Sci., 60, 337,345 (May/June 2009) Accepted for publication December 29, 2008. Synopsis During hair coloring a number of disulfide bonds in cystine are oxidized (1) to create cysteic acid, forming binding sites for metal ions such as Ca2+ and Cu2+ from tap water (2). The increased uptake of these metals can have a detrimental impact on fiber properties,for example, reducing shine and causing a poor wet and dry feel (3). In addition, the increased uptake of copper can also contribute to further fiber damage during subsequent coloring due to its ability to take part in metal-induced radical chemistry (4). It is important to know where in the fibers these metals are located in order to either effectively remove these metals or control their chemistry. Nanoscale secondary ion mass spectrometry (NanoSIMS) has been used to locate the calcium and copper within hair that has been treated with a colorant and washed multiple times in tap water containing these ions. Untreated hair is used as a baseline standard material. Images with up to 50-nm spatial resolution of the preferential locations of calcium uptake were obtained, showing a high concentration of calcium in the cuticle region of colored hair, specifically in the sulfur-rich regions (A-layer and exocuticle). [source] Skin moisturization by hydrogenated polyisobutene,Quantitative and visual evaluationINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 1 2010N. Dayan J. Cosmet. Sci., 60, 15,24 (January/February 2009) Synopsis Hydrogenated polyisobutene (HP) is used in topically applied cosmetic/personal care formulations as an emollient that leaves a pleasing skin feel when applied, and rubbed in after application. This effect, although distinguishable to the user, is difficult to define and quantify. Recognizing that some of the physical properties of HP such as film formation and wear resistance may contribute, in certain mechanisms, to skin moisturization, we designed a short-term pilot study to follow changes in skin moisturization. HP's incorporation into an o/w emulsion at 8% yielded increased viscosity and reduced emulsion droplet size as compared to the emollient ester CCT (capric/caprylic triglyceride) or a control formulation. Quantitative data indicate that application of the o/w emulsion formulation containing either HP or CCT significantly elevated skin moisture content and thus reduced transepidermal water loss (TEWL) by a maximal ,33% against the control formulation within 3 h and maintained this up to 6 h. Visual observation of skin treated with the HP-containing formulation showed fine texture and clear contrast as compared to the control or the CCT formulation, confirming this effect. As a result of increased hydration, skin conductivity, as measured in terms of corneometer values, was also elevated significantly by about tenfold as early as 20 min after HP or CCT application and was maintained throughout the test period. Throughout the test period the HP formulation was 5,10% more effective than the CCT formulation both in reduction of TEWL as well as in increased skin conductivity. Thus, compared to the emollient ester (CCT), HP showed a unique capability for long-lasting effect in retaining moisture and improving skin texture. [source] Simultaneous enhancement of cosmetic function and feel via molecular investigation of stickinessINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 2 2006H. Kudoh Moisturizing performance is often a very important factor in cosmetics. However, incorporating high concentrations of moisturizing agents often causes products to become sticky, a feel that consumers dislike. We suspected that the reason why high moisturizer content generates strong stickiness is that the polar group of the molecule is exposed at the surface. Thus, we began with a hypothesis that stickiness could be prevented through coexistence with a substance minimizing the exposure of polar group. Using glycerine as a moisturizing agent, we screened a large number of conventional materials for reducing stickiness but failed to find an effective compound. We then considered the use of a polymer for this purpose and synthesized a custom-made polymer, polyoxyethylene methacrylate 2-hydroxyethyl methacrylate fluoroalkyl acrylate copolymer (Polymer SR). Our experiments revealed that Polymer SR reduces the stickiness of glycerine by forming a hydrophobic film without hindering moisturizing performance. To clarify the mechanism by which Polymer SR reduces stickiness, we investigated the interaction between the Polymer SR and glycerine in solution using NMR and static light scattering measurements. We learned that Polymer SR and glycerine form a complex via hydrogen bonding of glycerine that results in orientation of the hydrophobic group of Polymer SR towards the outside. Subjective sensory tests supported the hypothesis that this hydrophobic orientation was maintained on the dermal surface even after application to skin. We believe that by taking into account the intended function and feel our technique for reducing the stickiness of moisturizers can be adopted for use with other substances and will contribute to future cosmetic research. [source] Conditioning polymers in today's shampoo formulations , efficacy, mechanism and test methodsINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 1 2000Hössel Synopsis Today's shampoo formulations are beyond the stage of pure cleansing of the hair. Additional benefits are expected, e.g. conditioning, smoothing of the hair surface, improvement of combability and lather creaminess. Cationic polymers play an important role in providing many of those features. Therefore, within the last few years their use in shampoos has increased greatly. In the only last two decades, shampoo designation has gradually changed from ,2-in-1' to ,3-in-1' and then to ,multifunctional', as at present. The consumer demands products which live up to their promises. Modern shampoos contain a wide variety of ingredients such as co-surfactants, vitamins and pro-vitamins, protein derivatives, silicones, natural-based plant extracts and other ,active ingredients', but there is still a need for conditioning polymers. The specific objective of this study is to assess the conditioning efficacy of cationic polymers and to investigate their mechanisms in a shampoo system. The investigations were carried out on formulations that contained sodium lauryl ether sulphate and different cationic polymers, e.g. Polyquaternium 7, 10, 11, cationic guar gum and Luviquat Care (Polyquaternium 44), a new branched copolymer of vinylpyrrolidone (VP) and quaternized vinylimidazolium salts (QVI). We used test methods relevant to the applications in question, such as combing force measurements, the feel of the hair and the creaminess of the lather, to assess the efficacy. Atomic force microscopy and electrokinetics (streaming potential) were used to detect polymer residues on treated hair. All the polymers under investigation improved the overall performance of the shampoo formulations. This was demonstrated by means of combing force measurements, sensorial tests and analytical methods, namely zeta potential measurement and atomic force microscopy. Polyquaternium 44 exhibited the best conditioning properties on wet hair without sacrificing removability or absence of build-up. The latter are the most striking weaknesses of cationic Guar Gum-based polymers. Polyquaternium 10 can also be removed from the hair after rinsing with anionic surfactant but it does not perform as well as Polyquaternium 44 in the fields of wet combability and sensorial criteria such as lather creaminess and feel of the hair. We postulate that the outstanding properties of Polyquaternium 44 as a conditioning agent for shampoos are due to its tailor-made ,branched' structure. There is a clear correlation between the molecular weight and the efficacy of the new copolymers of VP and QVI. Only cationic polymers with a very high molecular weight are effective as conditioners in shampoos based on anionic surfactants. Surprisingly, they do not have to have a high cationic charge. On the basis of all our results, our postulation is that the polymer residue which is responsible for conditioning does not form a flat layer on the hair. Rather, the polymer residue adsorbs with the few cationic moieties, while the uncharged part of the polymer forms loops, which are orientated away from the hair and which are responsible for the reduced friction between hairs. Résumé Les formulations actuelles de shampoing font plus qu'un simple nettoyage des cheveux. On en attend un intérêt supplémentaire, par exemple après-shampoing, lissage de la surface du cheveu, amélioration de la coiffabilité et aspect crémeux du savon. Les polymères cationiques jouent un rôle important dans l'apport de nombre de ces caractéristiques. Par conséquent, ces quelques dernières années leur utilisation a considérablement augmenté dans les shampoings. Dans les seules deux dernières décades, l'appellation du shampoing est progressivement passée de "2 en 1"à"3 en 1" puis ensuite à"multifonctionnel", comme actuellement. Le consommateur recherche des produits qui tiennent leurs promesses. Les shampoings modernes contiennent une grande diversité d'ingrédients tels que des co-tensioactifs, des vitamines et des provitamines, des dérivés de protéines, des silicones, des extraits à base de plantes naturelles et autres "ingrédients actifs", mais il existe toujours un besoin pour des polymères d'après shampoing. L'objectif spécifique de cette étude est d'évaluer l'efficacité comme après-shampoing de polymères cationiques et de rechercher leurs mécanismes dans le système de shampoing. Les recherches ont été menées sur des formulations qui contiennent du sulfate de lauryl éther sodium et différents polymères cationiques, par exemple du Polyquaternium 7, 10, 11, de la gomme de guar cationique et du Luviquat Care (Polyquaternium 44), un nouveau copolymère ramifié de vinylpyrrolidone (VP) et de sels quaternaires de vinylimidazolium (QVI). Nous avons utilisé les procédés de contrôle appropriées aux applications en question, tels que les mesures de force de coiffage, le toucher du cheveu et l'aspect crémeux du savon, pour évaluer l'efficacité. La microscopie atomique et l'électrocinétique (potentiel d'écoulement) ont été utilisées pour détecter les résidus de polymère sur le cheveu traité. Tous les polymères étudiés améliorent le comportement global des formulations de shampoing. Ceci est démontré au moyen des mesures de force de coiffage, des tests sensoriels et des méthodes analytiques, en l'occurrence la mesure du potentiel zêta et la microscopie atomique. Le Polyquaternium 44 présente les meilleures propriétés d'après-shampoing sur cheveu mouillé sans diminuer sa capacité d'élimination ou l'absence d'accumulation. Ces dernières sont les faiblesses les plus frappantes des polymères à base de gomme de guar cationique. Le Polyquaternium 10 peut aussi être éliminé du cheveu après rinçage avec un tensioactif anionique mais il ne se comporte pas aussi bien que le Polyquaternium 44 dans les domaines de la coiffabilitéà l'état mouillé et des critères sensoriels tels que l'aspect crémeux du savon et du toucher du cheveu. Nous supposons que les propriétés exceptionnelles du Polyquaternium 44 comme agent après-shampoing pour shampoings sont dues à sa structure "ramifiée" conçue sur mesure. Il existe une corrélation claire entre le poids moléculaire et l'efficacité des nouveaux copolymères de VP et QVI. Seuls les polymères cationiques avec un poids moléculaire très élevé sont efficaces comme après shampoings dans des shampoings à base de tensioactifs anioniques. Etonnamment, ils n'ont pas besoin d'avoir une charge cationique élevée. Sur la base de tous nos résultats, notre hypothèse est que le fragment de polymère qui est responsable du traitement ne forme pas une couche plate sur le cheveu. Le fragment de polymère adsorbe plutôt les quelques fragments cationiques, tandis que la partie non chargée du polymère forme des boucles, qui sont orientées à l'extérieur du cheveu et qui sont responsables de la friction réduite entre les cheveux. [source] ,Seen but not heard', young people's experience of advocacyINTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 1 2005Jane Boylan This article draws on two pieces of empirical research undertaken in England with young people in public care. The research examined young people's experiences of a range of advocacy services, and the extent to which the involvement of an advocate facilitated young people's voices being heard in decision-making. The research responded to contemporary concerns about children's participatory rights, citizenship and social inclusion, set in the context of the United Nations Convention on the Rights of the Child. This article examines the strengths and limitations of advocacy for young people in public care and compares the different types of advocacy services that are available to young people and considers the extent to which adult perceptions of childhood and youth frame the services that are offered. It provides a comparison of the outcomes for young people who have had an advocate and those who have not. The concluding discussion argues that young people in public care feel excluded and marginalised from decision-making processes, and that advocacy has a pivotal role to play in placing at centre stage the wishes and feelings of young people. [source] Levels of comfort and ease among patients suffering from urinary incontinenceINTERNATIONAL JOURNAL OF UROLOGICAL NURSING, Issue 2 2007Michal Rassin Abstract Urinary incontinence is a common phenomenon among women, which harms social ties and is perceived as embarrassing and incurable. Despite its prevalence, there are few studies that have examined how those affected by this syndrome feel. The goal of this study was to examine the personal characteristics and levels of comfort among women suffering from urinary incontinence. The study included 50 women who had been diagnosed as suffering from urinary incontinence. The participants answered the Urinary Incontinence and Frequency Comfort Questionnaire, which examines levels of physical, mental, social and environmental comfort. , reliability has been found to be high in previous studies (,= 0·82). Our findings indicated that urinary incontinence occurred among the patients from several times a day to several times a week caused by sneezing, coughing and laughing. Most participants delayed treatment for up to 3 years. The general level of comfort was identified as medium low (SD = 0·04, M= 2·95) from a possible range of 1,6. Particularly low levels of comfort were recorded on items such as ,I feel clean and fresh,',finding a toilet in close proximity is a worrisome issue when I exit the house' and ,I fear having sex due to the urinary incontinence problem'. Identifying patients' needs and understanding their emotions are a useful basis for nursing intervention in promoting quality of life. [source] Discrimination and Well-Being: Perceptions of Refugees in Western AustraliaINTERNATIONAL MIGRATION REVIEW, Issue 1 2008Farida Fozdar This paper reports the apparent paradox of high levels of discrimination experienced by humanitarian migrants to Australia, in the labor market and everyday life, yet simultaneous reporting of positive well-being. How can people feel discriminated against, yet still be relatively satisfied with life? The study draws on quantitative and qualitative data from a study of 150 refugees from the former Yugoslavia, the Middle East, and Africa. Possible reasons for the level of well-being are explored, including "relative deprivation theory," as well as various resiliency and mitigating factors, including personal and social supports. The notion of eudaimonic well-being , whereby experiences of difficulty produce positive well-being , is also applied to the findings. The negative experiences and perceptions appear to map onto low-level dissatisfaction or disgruntlement, and specifically directed or contained disappointment, rather than serious dissatisfaction with life generally, orientation to Australia, or negative subjective well-being. [source] Parent's involvement in decisions when their child is admitted to hospital with suspected shunt malfunction: study protocolJOURNAL OF ADVANCED NURSING, Issue 10 2009Joanna Smith Abstract Title., Parent's involvement in decisions when their child is admitted to hospital with suspected shunt malfunction: study protocol. Aim., This paper outlines the protocol for a study aimed at exploring parent's involvement during professional,parent interactions and decisions about their child's care in the context of suspected shunt malfunction. Background., Hydrocephalus is a long-term condition treated primarily by the insertion of a shunt that diverts fluid from the brain to another body compartment. Shunts frequently malfunction, and parents of children with shunted hydrocephalus are responsible for recognizing and responding to shunt complications. Parents feel that interactions with professionals when they seek healthcare advice for their child do always not encourage active participation in care decisions. Methods., The study design is based on qualitative methodologies: a combination of conversation analysis applied to consultation recordings of professional,parent interactions when a child is admitted to hospital with suspected shunt malfunction, and semi-structured follow-up interviews with the same participants within 2 weeks of the consultation. Participants., This is a prospective study and participants will be purposefully selected. Parents of children who have been admitted to hospital with suspected shunt malfunction and healthcare professionals responsible for the initial assessment of the child will be invited to participate. Discussion., The study will identify how decisions about a child's care are negotiated between parents and healthcare professionals at key stages of the care pathway. In addition, examining interactions between healthcare professionals and parents may identify approaches that support or hinder parents in contributing to the decision-making processes when they seek advice from healthcare professionals. [source] Cannabis: What Makes University Students More or Less Likely to Use It?JOURNAL OF APPLIED BIOBEHAVIORAL RESEARCH, Issue 2 2006Frances V. O'Callaghan University students' motivations for using or not using cannabis were investigated. Students (n = 189) aged 17 to 29 years completed a survey to assess their intention to use cannabis and their beliefs about (a) advantages and disadvantages of using cannabis; (b) their perceptions of what significant others think they should do in relation to cannabis use; and (c) factors that might encourage them to use or not use cannabis. Two weeks later, they completed a follow-up survey asking about their actual behavior over the previous 2 weeks. Compared to non-users, users believed more strongly that cannabis would help them fit in with their friends, feel relaxed, forget their worries, and enjoy themselves. They also believed that their close friends, partner/spouse, siblings, and workmates would approve of their using cannabis. Users believed that certain factors (e.g., force of habit, wanting to relax, feeling stressed, being around other people using cannabis) would encourage them to use, while non-users rated work and study as strong reasons for not using cannabis. Beliefs that are relevant to users and non-users in education campaigns can be targeted to reduce the negative consequences of use in tertiary settings. [source] Influence in the Ivory Tower: Examining the Appropriate Use of Social Power in the University ClassroomJOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 11 2007Steven M. Elias A study was conducted to determine how appropriate university students feel it is for professors to use varying bases of social power as a means of influence. Participants (n = 91) completed a modified version of the Interpersonal Power Inventory (Raven, Schwarzwald, & Koslowsky, 1998) and a demographic questionnaire. Students rated the use of soft power as significantly more appropriate than harsh power. Repeated-measures ANOVA indicated that informational and expert power were thought to be the most appropriate bases for professors to use, and a gender effect was observed such that female students rated the use of social power in the classroom as significantly less appropriate than did male students. Implications for university instructors and other power holders are discussed. [source] Psychobiogeography: meanings of nature and motivations for a democratized conservation ethicJOURNAL OF BIOGEOGRAPHY, Issue 6 2001Stephen Trudgill The language of ecosystem science is pervaded by value-laden terms such as pristine, fragile, disturbance, balance, dominance and alien species. Such terms have high status and are often used in the rhetoric of the conservation ethic. Here, I consider the possibility of the use of less value-laden terms such as change, increase, decrease and so on. This would distinguish between values and perceived trends or states and leave ecosystem science to deal with what is verifiable. However, I also consider the opposite point of view, in that the value-laden terms, like ,the balance of nature', relate to how a wide range of people feel about nature and are effective emotive motivators of the conservation ethic in society, providing a common language for a discourse between ecosystem scientists and other people. [source] Bullying in school and adolescent sense of empowerment: an analysis of relationships with parents, friends, and teachers,JOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 3 2008Maury Nation Abstract We explore the development of bullying and victimization in school by investigating 11-, 13- and 15-year-olds' sense of interpersonal empowerment with parents, friends and teachers. A national sample of 4386 male and female students from 243 middle and secondary schools in Italy were surveyed. Boys were more likely than girls to be bullies and more likely to have been a bully/victim. Victimization and the likelihood of being both a bully and a victim declined with age. Bullying increased with age among boys whereas for girls it was slightly more prevalent at age 13 than ages 11 or 15. The sense of empowerment students experience with their teachers decreased in the older cohorts. Disempowered relationships with teachers consistently predicted bullying behaviour. Higher social competence was reported by 13- and 15-year-old bullies. Chronically bullied students had lower social competence in all age cohorts. Otherwise, predictors of victimization varied by age: 11-year-old victims felt less empowered by their teachers; 15-year-old victims reported more difficulties in negotiating cooperative relationships with parents. Bullies in all cohorts and younger bully/victims feel less empowered by their teachers. These findings suggest that students who are disempowered by teachers may either compensate by oppressing (bullying) peers or generalize the power differential with peers (become a victim).

Evans Sense of Community theory suggests that people feel more attracted to groups and settings in which they feel influential or powerful. Unfortunately, young people have no voice or influence in many of the contexts in which they find themselves. Furthermore, teenagers are often unequipped and undersupported to participate fully and feel like they are making meaningful contributions to society. This is especially the case for young people who are disadvantaged or members of a minority groups. A two-part study was undertaken to explore sense of community in adolescents. The first phase utilized existing tools to measure adolescent sense of community in school, neighborhood, and city contexts. The second phase of the study relied on in-depth interviews with teenagers to better understand how they construct their sense of community. This article reports findings from the second phase and looks closely at the sense of community domain of "influence" as it applies to adolescents. Interviews with young people suggest that they feel a stronger self-described sense of community in contexts where they experience voice and resonance, some power and influence, and adequate adult support and challenge. © 2007 Wiley Periodicals, Inc.

Although skin feel has always been a key esthetic parameter, consumers increasingly select products based on a more complete sensory experience, including texture, scent, visual esthetics in the container, tactile effects on application, and the performance of active ingredients such as vitamins or sunscreen.
