Controlling and developing native people : anthropology, government and the management of indigenous peoples in Australia and its territories 1920 to 1950

Examines the relationship between anthropology and native administration in the Australian territories of Papua and New Guinea and the Northwest of Australia between 1920 and 1950. Is is argued that anthropology needed colonialism rather than colonialism needing anthropology.

The influence of gender on perceived treatment need among a community sample of substance users

Purpose: Most individuals do not perceive a need for substance use treatment despite meeting diagnostic criteria for substance use disorders and they are least likely to pursue treatment voluntarily. There are also those who perceive a need for treatment and yet do not pursue it. This study aimed to understand which factors increase the likelihood of perceiving a need for treatment for individuals who meet diagnostic criteria for substance use disorders in the hopes to better assist with more targeted efforts for gender-specific treatment recruitment and retention. Using Andersen and Newman's (1973/2005) model of individual determinants of healthcare utilization, the central hypothesis of the study was that gender moderates the relationship between substance use problem severity and perceived treatment need, so that women with increasing problems due to their use of substances are more likely than men to perceive a need for treatment. Additional predisposing and enabling factors from Andersen and Newman's (1973/2005) model were included in the study to understand their impact on perceived need. Method: The study was a secondary data analysis of the 2010 National Survey on Drug Use and Health (NSDUH) using logistic regression. The weighted sample consisted of a total 20,077,235 American household residents (The unweighted sample was 5,484 participants). Results of the logistic regression were verified using Relogit software for rare events logistic regression due to the rare event of perceived treatment need (King & Zeng, 2001a; 2001b). Results: The moderating effect of female gender was not found. Conversely, men were significantly more likely than women to perceive a need for treatment as substance use problem severity increased. The study also found that a number of factors such as race, ethnicity, socioeconomic status, age, marital status, education, co-occurring mental health disorders, and prior treatment history differently impacted the likelihood of perceiving a need for treatment among men and women. Conclusion: Perceived treatment need among individuals who meet criteria for substance use disorders is rare, but identifying factors associated with an increased likelihood of perceiving need for treatment can help the development of gender-appropriate outreach and recruitment for social work treatment, and public health messages.

Insect distributions and sampling protocols for stored commodities

Purpose of review: This review provides an overview on the importance of characterising and considering insect distribution infor- mation for designing stored commodity sampling protocols. Findings: Sampling protocols are influenced by a number of factors including government regulations, management practices, new technology and current perceptions of the status of insect pest damage. The spatial distribution of insects in stored commodities influ- ences the efficiency of sampling protocols; these can vary in response to season, treatment and other factors. It is important to use sam- pling designs based on robust statistics suitable for the purpose. Future research: The development of sampling protocols based on flexible, robust statistics allows for accuracy across a range of spatial distributions. Additionally, power can be added to sampling protocols through the integration of external information such as treatment history and climate. Bayesian analysis provides a coherent and well understood means to achieve this.

Huumeriippuvuudesta toipuminen Nimettömien Narkomaanien toveriseurassa

The subjects of this study are Narcotics Anonymous (NA), a non-profit, peer-support-based fellowship, its recovery programme, and the former drug addicts who consider themselves members of the fellowship. The study data consist of episodic interviews (n=24) and questionnaires (n=212). In the collection of questionnaire data, survey research methods had to be applied judiciously. This study analyses NA members background and their substance abuse and treatment history, as well as factors that have contributed to or hindered their bonding with NA. A recovery model is presented that stems from NA s written and oral tradition, and which has been conceptualised into NA s recovery theory. At its simplest, NA s recovery theory can be described in two sentences: 1) There are drug dependent addicts who have an addiction disease. 2) Through an NA way of life, recovery is possible. In this study, addiction and addiction disease are described through recovery stories shared at NA. It also describes how the way of life offered by NA supports recovery from drug addiction, the way of life which recovering addicts have adopted, and how they have done so. The study also presents results that, based on the study data, emerge from participation in the NA programme, and describes how the NA recovery theory works in practice, i.e. how NA members utilise the tools provided by the fellowship and how the lives of recovering addicts change during their membership. Furthermore, this study also discusses criticism of NA. According to the study, NA affects the lives of recovering drug addicts in a number of ways. People of different ages and with a variety of personal, treatment and drug abuse histories seem to benefit from membership of NA. Viewed from the outside, NA may appear as strictly normative, but in practice each member can adapt the programme in a way that suits him/her best. Indeed, flexibility is one of the strengths of NA, but without more extensive knowledge of the fellowship, it is possible that the norms reflected in NA texts or the fanaticism of individual NA members may drive some people away. Due to the increasing number of NA members, the association is also able to provide more alternatives. This study confirms the view that peer support is important, as well as the fact that an official treatment system is required in parallel with peer support activities. NA can never fully replace professional support, neither should it be left with sole responsibility for recovering addicts.

Suomenlinnan Kustaanmiekan ketokasvillisuus ja siihen vaikuttavat tekijät

Suomenlinna on yksi Helsingin suosituimmista matkailu- ja kulttuurinähtävyyksistä. Kustaanmiekan, samoin kuin koko Suomenlinnan luonto on muodostunut perinteisestä suomalaisesta saaristoluonnosta ja vuosisatojen saatossa paikalle tulleista linnoituksien kasvistosta. Saaren vaihtelevien elinympäristöjen johdosta alueen kasvillisuus on hyvin rikasta. Linnoituksien monet kasvilajit ovat tulleet tulokaskasveina eri puolilta Eurooppaa sekä Venäjältä. Suurin osa Suomenlinnan alueesta on kallioketoa ja tämän lisäksi myös valliketoa, joista molemmat kuuluvat suojeltaviin alueisiin. Kustaanmiekan niityillä kasvaa keto- ja paahdelajeja, kuten harvinaista ketonoidanlukkoa (Botrychium lunaria L.) sekä ketoneilikkaa (Dianthus deltoides L.). Tämän tutkimuksen ensisijaisena tarkoituksena oli kartoittaa Kustaanmiekan alueen kesäkauden 2009 ketokasvilajisto ja eri putkilokasvilajien runsaus. Tutkimuksessa selvitettiin myös maaperätekijöiden ja alueen hoitohistorian mahdollista vaikutusta ketokasvilajistoon. Tutkimuksessa kartoitettiin kymmenen eri kedon kasvillisuus Suomenlinnan Kustaanmiekan linnoitusalueella. Kedot sijaitsivat eri puolilla Kustaanmiekkaa, sellaisilla paikoilla, missä ketokasvillisuus oli runsainta. Maastotyöt suoritettiin kesä- ja heinäkuussa laskemalla jokaisen kedon ruutujen putkilokasvien peittävyydet sekä listaamalla ylös myös ruutujen ulkopuoliset kevät- ja loppukesän kukkijat touko- ja elokuussa. Maaperän ominaisuuksien määrittämiseksi otettiin kultakin kedolta pintamaanäytteet elokuussa. Muita tutkittuja muuttujia olivat maapinnan kaltevuus sekä sammalen, karikkeen, paljaan maan, kenttäkasvillisuuden pohjakerros ja kallion osuus tutkimusruuduilla. Ketojen kasvillisuuden keskimääräinen korkeus mitattiin kesä- ja heinäkuussa. Kasvistossa oli selviä eroavaisuuksia ketojen välillä. Kasvilajien määrä vaihteli ketojen kokonaislajimäärän ollessa 40-60 kasvilajia. Yhteensä kedoilta löytyi 120 eri putkilokasvilajia, joista useimmat kukkivat sekä kesä- että heinäkuussa. Ketojen kasvilajimäärä vaihteli yhdellä neliömetrillä 6,3-13,6 kasvilajiin, minkä lisäksi Shannon-Wienerin diversiteetti-indeksi vaihteli 1,4-2,3 arvon välillä. Yleisimpiä lajeja, joita kedoilla tavattiin, olivat muun muassa siankärsämö (Achillea millefolium L.), koiranheinä (Dactylis glomerata L.), juolavehnä (Elymus repens L.) ja hopeahanhikki (Potentilla argentea L.). Alueella kasvoi myös muutamia sotatulokaslajeja kuten harmiota (Berteroa incana L.), ukonpalkoa (Bunias orientalis L.) ja karvahorsmaa (Epilobium hirsutum L.). Maaperätekijöillä, kuten suurella fosforin pitoisuudella ei ollut vaikutusta kasvilajien määrään kedoilla. Vain maan pH ja johtoluku korreloivat positiivisesti ketojen kasvillisuuden korkeuden kanssa. Vaikka tulosten perusteella ketojen hoidolla ei ollut vaikutusta ketojen kasvillisuuden määrään, voidaan kuitenkin olettaa oikeanlaisen hoidon parantavan tyypillisten ketokasvien kilpailukykyä muita niittykasveja kohtaan.

Bismuth-doped zinc aluminosilicate glasses and glass-ceramics with ultra-broadband infrared luminescence

Broadband infrared luminescence covering the optical telecommunication wavelength region of 0, E and S bands was observed from bismuth-doped zinc aluminosilicate glasses and glass-ceramics. The spectroscopic properties of the glasses and glass-ceramics depend on the thermal-treatment history. With the appearance of gahnite (ZnAl2O4) crystalline phase, the fluorescent peak moves to longer wavelength, but the fluorescent intensity decreases. The similar to 1300 nm fluorescence with a FWHM larger than 250 nm and a lifetime longer than 600 mu s possesses these optical materials with potential applications in laser devices and broadband amplifiers. The broad infrared luminescence from the bismuth-doped zinc aluminosilicate glasses and glass-ceramics might be from BiO or bismuth clusters rather than from Bi5+ and Bi3+. (c) 2005 Elsevier B.V.

Determination of ranitidine in urine by capillary electrophoresis-electrochemiluminescent detection

The fast analysis of ranitidine is of clinical importance in understanding its efficiency and a patient's treatment history. In this paper, a novel determination method for ranitidine based on capillary electrophoresis-electrochemiluminescence detection is described. The conditions affecting separation and detection were investigated in detail. End-column detection of ranitidine in 5 mM Ru(bpy)(3)(2+) solution at applied voltage of 1.20 V was performed. Favorable ECL intensity with higher column efficiency was achieved by electrokinetic injection for 10 s at 10 kV. The R.S.D. values of ECL intensity and migration time were 6.38 and 1.84% for 10(-4) M and 6.01 and 0.60% for 10(-5) M, respectively. A detection limit of 7 x 10(-8) M (S/N = 3) was achieved. The proposed method was applied satisfactorily to the determination of ranitidine in urine in 6 min.

Influence of corneal structure, corneal responsiveness, and other ocular parameters on tonometric measurement of intraocular pressure.

PURPOSE: To estimate the relationships between ocular parameters and tonometrically measured intraocular pressure (IOP), to determine the influence of ocular parameters on different instrument measurements of IOP, and to evaluate the association of ocular parameters with a parameter called hysteresis. METHODS: Patients presenting at a glaucoma clinic were recruited for this study. Subjects underwent IOP measurement with the Goldmann applanation tonometer (GAT), the TonoPen, and the Reichert Ocular Response Analyzer (ORA), and also measurements of central corneal thickness (CCT), axial length, corneal curvature, corneal astigmatism, central visual acuity, and refractive error. Chart information was reviewed to determine glaucoma treatment history. The ORA instrument provided a measurement called corneal hysteresis. The association between measured IOP and the other ocular characteristics was estimated using generalized estimating equations. RESULTS: Among 230 patients, IOP measurements from the TonoPen read lowest, and ORA read highest, and GAT measurements were closest to the mean IOP of the 3 instruments. In a multiple regression model adjusting for age, sex, race, and other ocular characteristics, a 10 microm increase in CCT was associated with an increase of 0.79 mm Hg measured IOP in untreated eyes (P<0.0001). Of the 3 tonometers, GAT was the least affected by CCT (0.66 mm Hg/10 mum, P<0.0001). Hysteresis was significantly correlated with CCT with a modest correlation coefficient (r=0.20, P<0.0007). CONCLUSIONS: Among parameters related to measured IOP, features in addition to CCT, such as hysteresis and corneal curvature, may also be important. Tonometric instruments seem to be affected differently by various physiologic characteristics.

La stimulation du nerf vague pour le traitement de la dépression réfractaire : les résultats après un an de suivi

La stimulation du nerf vague (SNV) a reçu l’approbation de Santé Canada en 2001, comme en Europe, pour le traitement de la dépression réfractaire et en 2005 aux États-Unis. Les études européennes et américaines rapportent un taux de réponse de 50% et de rémission de 30% après un an de traitement. La sélection des patients, encadrée par la recherche de marqueurs biologiques et des critères de résistance, pourrait contribuer à améliorer les taux de réponse. Cette étude décrit le suivi des patients ambulatoires souffrant de dépression réfractaire, d’un spectre unipolaire ou bipolaire (n=13) sous SNV. Une révision exhaustive de l’histoire médicale et thérapeutique précède une évaluation clinique intensive. Si un consensus d’équipe est obtenu, une investigation clinique à la recherche des marqueurs biologiques est effectuée. Ceci inclut une tomographie par émission de photons simples (SPECT), une tomographie par émission de positrons (TEP), une formule sanguine complète, un test de suppression à la dexaméthasone (DST), une collecte d’urine 24h (catécholamines et cortisol), une polysomnographie et une évaluation neuropsychologique abrégée. Après 1 an de traitement, 61,5% (8/13) des patients ont atteint le seuil de réponse (diminution de 50% des symptômes), dont 87.5% (7/8) en rémission. Les patients diagnostiqués d’un trouble bipolaire, présentant un DST anormal et/ou avec déficits cognitifs ont répondu au traitement et poursuivent leur rémission après 2 ans. Une sélection minutieuse des patients pour le SNV serait une méthode efficace pour traiter les dépressions réfractaires, notamment pour prévenir les rechutes, amenant un état euthymique durable pour la plupart des patients.

Antidepressant medication may moderate the effect of depression duration on hippocampus volume

Abstract.
Hippocampus volume has been frequently, but not universally reported to be reduced in people with major depression relative to age-matched healthy controls. Among the potential reasons for this discrepancy in finding across studies is the effect of antidepressant medication. Hippocampus volume was determined by MRI (1.5 Tesla) for 10 people diagnosed with major depression for who detailed history of depression and antidepressant treatment history were known, and 10 age-matched healthy controls with no history of depression. Left, but not right, hippocampus volumes were significantly smaller in the patient group compared to the controls. Furthermore, there was a significant correlation such that left hippocampus volume was smaller with increasing lifetime duration of depression. However, this relationship was moderated by a significant correlation such that greater lifetime duration of antidepressant medication was associated with larger left hippocampus volume.
The findings support the contention that antidepressant medication may act to normalize hippocampus volume.

Room temperature photoluminescence of BCT prepared by Complex Polymerization Method

Correlation between the surface morphology and structure and the photoluminescence of amorphous PbTiO3 thin films obtained by the chemical route

A polymeric precursor method was used to synthesis PbTiO3 amorphous thin film processed at low temperature. The luminescence spectra of PbTiO3 amorphous thin films at room temperature revealed an intense single-emission band in the visible region, the visible emission band was found to be dependent on the thermal treatment history, Photoluminescence properties Versus different annealing temperatures were investigated. The experimental results (XRD, AFM, FL) indicate that the nature of photoluminescence (PL) must be related to the disordered structure of PbTiO3 amorphous thin films, Copyright (C) 2000 John Wiley & Sons, Ltd.

Impact of IL28B genotype on first-week response to telaprevir-based therapy in HIV-HCV coinfection

BACKGROUND IL28B genotype predicts response to treatment against hepatitis C virus (HCV) with pegylated interferon/ribavirin (PR) and impacts on the outcome of therapy including telaprevir (TVR). This study aimed to determine the influence of the favorable IL28B genotype on early viral kinetics during therapy with TVR/PR in HIV/HCV-coinfected patients. METHODS All HIV/HCV genotype 1-coinfected subjects who received TVR/PR for at least 4 weeks were included from populations prospectively followed in 22 centers throughout Germany, Switzerland and Spain. RESULTS Of the 129 subjects included, 38 (29.5%) presented with IL28B genotype CC and 94 (72.9%) were treatment-experienced. Ninety-six (73.8%) patients showed undetectable plasma HCV-RNA at treatment week (W) 4: 30 (78.9%) of the IL28B-CC carriers and 65 (71.4%) of the non-CC carriers (p=0.377). Among treatment-naïve patients, proportions of undetectable HCV-RNA among IL28B-CC versus non-CC carriers were 8/9 (88.9%) versus 3/9 (33.3%, p=0.016) and 14/17 (82.4%) versus 11/18 (61.1%, p=0.164) at W2 and W4. The decrease of HCV-RNA at W2 and W4 was similar among the IL28B carriers. CONCLUSIONS IL28B genotype does not predict W4 response to TVR/PR in HIV/HCV-coinfected patients, regardless of their treatment history. However, there is evidence of an impact on response during the first weeks in treatment-naïve patients.
