Expertise and decision making among clinicians in investigations of alleged child sexual abuse

The purpose of the present thesis was to explore different aspects of decision making and expertise in investigations of child sexual abuse (CSA) and subsequently shed some light on the reasons for shortcomings in the investigation processes. Clinicians’ subjective attitudes as well as scientifically based knowledge concerning CSA, CSA investigation and interviewing were explored. Furthermore the clinicians’ own view on their expertise and what enhances this expertise was investigated. Also, the effects of scientific knowledge, experience and attitudes on the decision making in a case of CSA were explored. Finally, the effects of different kinds of feedback as well as experience on the ability to evaluate CSA in the light of children’s behavior and base rates were investigated. Both explorative and experimental methods were used. The purpose of Study I was to investigate whether clinicians investigating child sexual abuse (CSA) rely more on scientific knowledge or on clinical experience when evaluating their own expertise. Another goal was to check what kind of beliefs the clinicians held. The connections between these different factors were investigated. A questionnaire covering items concerning demographic data, experience, knowledge about CSA, selfevaluated expertise and beliefs about CSA was given to social workers, child psychiatrists and psychologists working with children. The results showed that the clinicians relied more on their clinical experience than on scientific knowledge when evaluating their expertise as investigators of CSA. Furthermore, social workers possessed stronger attitudes in favor of children than the other groups, while child psychiatrists had more negative attitudes towards the criminal justice system. Male participants held less strong beliefs than female participants. The findings indicate that the education of CSA investigators should focus more on theoretical knowledge and decision making processes as well as the role of beliefs In Study II school and family counseling psychologists completed a Child Sexual Abuse Attitude and Belief Scale. Four CSA related attitude and belief subscales were identified: 1. The Disclosure subscale reflecting favoring a disclosure at any cost, 2. The Pro-Child subscale reflecting unconditional belief in children's reports, 3. The Intuition subscale reflecting favoring an intuitive approach to CSA investigations, and 4. The Anti Criminal Justice System subscale reflecting negative attitudes towards the legal system. Beliefs that were erroneous according to empirical research were analyzed separately. The results suggest that some psychologists hold extreme attitudes and many erroneous beliefs related to CSA. Some misconceptions are common. Female participants tended to hold stronger attitudes than male participants. The more training in interviewing children the participants have, the more erroneous beliefs and stronger attitudes they hold. Experience did not affect attitudes and beliefs. In Study III mental health professionals’ sensitivity to suggestive interviewing in CSA cases was explored. Furthermore, the effects of attitudes and beliefs related to CSA and experience with CSA investigations on the sensitivity to suggestive influences in the interview were investigated. Also, the effect of base rate estimates of CSA on decisions was examined. A questionnaire covering items concerning demographic data, different aspects of clinical experience, self-evaluated expertise, beliefs and knowledge about CSA and a set of ambiguous material based on real trial documents concerning an alleged CSA case was given to child mental health professionals. The experiment was based on a 2 x 2 x 2 x 2 (leading questions: yes vs no) x (stereotype induction: yes vs no) x (emotional tone: pressure to respond vs no pressure to respond) x (threats and rewards: yes vs no) between-subjects factorial design, in which the suggestiveness of the methods with which the responses of the child were obtained were varied. There was an additional condition in which the material did not contain any interview transcripts. The results showed that clinicians are sensitive only to the presence of leading questions but not to the presence of other suggestive techniques. Furthermore, the clinicians were not sensitive to the possibility that suggestive techniques could have been used when no interview transcripts had been included in the trial material. Experience had an effect on the sensitivity of the clinicians only regarding leading questions. Strong beliefs related to CSA lessened the sensitivity to leading questions. Those showing strong beliefs on the belief scales used in this study were even more prone to prosecute than other participants when other suggestive influences than leading questions were present. Controversy exists regarding effects of experience and feedback on clinical decision making. In Study IV the impact of the number of handled cases and of feedback on the decisions in cases of alleged CSA was investigated. One-hundred vignettes describing cases of suspected CSA were given to students with no experience with investigating CSA. The vignettes were based on statistical data about symptoms and prevalence of CSA. According to the theoretical likelihood of CSA the children described were categorized as abused or not abused. The participants were asked to decide whether abuse had occurred. They were divided into 4 groups: one received feedback on whether their decision was right or wrong, one received information about cognitive processes involved in decision making, one received both, and one did not receive feedback at all. The results showed that participants who received feedback on their performance made more correct positive decisions and participants who got information about decision making processes made more correct negative decisions. Feedback and information combined decreased the number of correct positive decisions but increased the number of correct negative decisions. The number of read cases had in itself a positive effect on correct positive decision.

Análise de ácidos graxos por eletroforese capilar utilizando detecção condutométrica sem contato

This article describes a novel approach to the separation of fatty acids ranging from 8 to 20 carbons using capillary electrophoresis with contactless conductivity detection. Complete separation of nine linear chain fatty acids (from C8:0 to C20:0) was achieved in 15 min under normal polarity operation. Limits of detection ranged from 35 to 319 µmol L-1 for C20:0 to C8:0, respectively. The optimized running electrolyte composition was 5.0 mmol L-1 phosphate buffer at pH 7, 4.0 mmol L-1 dimethyl-b-cyclodextrin, 2.0 mmol L-1 trimethyl-b-cyclodextrin, acetonitrile 50% (v/v), and methanol 20% (v/v). The applicability of the separation system was demonstrated by the analysis of coconut vegetable oil.

Ethical problems occurring during the practical training period of Finnish nursing students The present study focused on nursing students adopting the professional code of conduct during their supervised practical training. The study was carried out in two phases. During the first phase, the objective was to survey ethical problems occurring in practical training as well as how these problems are detected and resolved by nursing students and their supervisors at different stages of their studies. In the second phase, the capability of the nursing students about to graduate to detect and resolve ethical problems was described and analyzed. The students’ capacity for self-instruction, independent search for information as well as factors related to teaching of ethics were determined within this phase. Further, an extensive literature review was carried out to complement the study. Thus, the main objective of the thesis was to make suggestions for the development of the teaching of ethics and supervision in nursing studies and in practice. In the first part of the empirical phase (2002–2005), the views of the nursing students (n =18) were clarified with themed open essay questions. Furthermore, the views of the supervising nurses (n = 115) were established by utilizing a series of themed questions and group interviews. During the second phase (2006–2007), the data for the analyses were collected from nursing students in their graduating stage (n = 319) by a national Internet-based questionnaire. The results of the first phase were examined with contentanalysis and those of the second phase both statistically and by using content analysis. Ethical problems occurring during supervised practical training were typically connected to a patient or a client, a member of the nursing staff or to a student, while solutions were connected to preparation and the action to solve the problem in question. Ethical dilemmas were classified as legal, ethical comportment and uncertainty problems as well as personal and institutional ones. The solutions for these problems were further grouped as based on facts, instructor/staff/member/specialist or patient/client/relative. The results showed that although the nursing students about to graduate had detected many ethical problems both independently as well as together with the nursing staff during every practical training period, they were able to resolve only few of them. Ethical problems were most frequently encountered during training in psychiatric nursing. On the grounds of their own impressions, the nursing students stated that their ability to detect and solve ethical problems improved during their training period. The primary factors related to this enhancement of their skills were teaching and the students’ readiness for selfinstruction. Gender, orientation of the studies and age were observed to be the most important among the underlying factors influencing the capability to detect and solve ethical problems as well as to engage in self-instruction. Based on the results obtained, suggestions for development as well as topics for further studies are presented through teaching of professional ethics and supervision during practical training.

Development and validation of spectroscopic methods for simultaneous estimation and dissolution of ofloxacin and ornidazole in tablet dosage forms

The aim of this work was to develop and validate simple, accurate and precise spectroscopic methods (multicomponent, dual wavelength and simultaneous equations) for the simultaneous estimation and dissolution testing of ofloxacin and ornidazole tablet dosage forms. The medium of dissolution used was 900 ml of 0.01N HCl, using a paddle apparatus at a stirring rate of 50 rpm. The drug release was evaluated by developed and validated spectroscopic methods. Ofloxacin and ornidazole showed 293.4 and 319.6nm as λmax in 0.01N HCl. The methods were validated to meet requirements for a global regulatory filing. The validation included linearity, precision and accuracy. In addition, recovery studies and dissolution studies of three different tablets were compared and the results obtained show no significant difference among products.

Kaatumisvaaraa lisäävät lääkkeet; Porissa toteutettu iäkkäiden monitekijäinen kaatumisten ehkäisy

Kaatumiset ovat ikääntyvien yleisimpiä tapaturmia. Niiden seuraukset voivat olla vakavia. Yksilöllisesti toteutetut ehkäisyohjelmat ovat vähentäneet kaatumisvaarassa olevien iäkkäiden kaatumisia. Psyykenlääkkeiden on osoitettu lisäävän kaatumisia ja murtumia. Niiden lopettaminen on vähentänyt kaatumisvaaraa. Monitekijäiset ehkäisyohjelmat kuvaavat harvoin psyykenlääkkeiden vähentämisen menetelmiä ja tuloksia. Satunnaistettuun, kontrolloituun kaatumisten moneen vaaratekijään kohdistettuun ehkäisytutkimukseen osallistui 591 porilaista. Tässä tutkimuksessa selvitettiin kotona asuvien 65 vuotta täyttäneiden, tutkimusta edeltäneiden 12 kuukauden aikana ainakin kerran kaatuneiden henkilöiden psyykenlääkkeiden käyttö, niiden vähentämisen onnistuminen ja vaikutus sekä ehkäisyohjelman merkitys kaatumisten ilmaantumiseen. Lisäksi tutkittiin kaatumisvamman takia hoitoon hakeutuneiden kaatumisvaaratekijöiden tunnistamista ja uusien kaatumisten ja murtumien ehkäisemiseksi suunniteltuja toimenpiteitä perusterveydenhuollossa ja erikoissairaanhoidossa. Joka neljäs osallistuja käytti säännöllisesti psyykenlääkkeitä. Kertaneuvonta niiden vähentämisestä, johon sisältyi kirjalliset ohjeet lääkemuutoksista ja luento lääkkeiden vaikutuksista kaatumisvaaraan, vähensi säännöllisten psyykenlääkkeiden käyttäjien lukumäärää 22 % ja bentsodiatsepiineja tai niiden kaltaisia lääkkeitä käyttävien lukumäärää 35%. Kaatumisen vuoksi terveyskeskukseen ja keskussairaalaan hakeutuneiden iäkkäiden kaatumisvaaratekijöiden selvittelyyn ja uusien kaatumisten tai murtumien ehkäisyyn kiinnitettiin erittäin vähän huomiota. Toimenpiteet keskittyivät syntyneiden vammojen tutkimiseen ja hoitoon. Monitekijäinen ehkäisyinterventio vähensi masentuneiden ja monikaatuilijoiden kaatumisia, mutta ei kaikkien osallistujien kaatumisten määrää 12 kuukauden ehkäisyohjelman aikana. Erityisesti bentsodiatsepiiniryhmän lääkkeitä käyttävät verrokkiryhmän jäsenet joutuivat herkemmin kaatumisen vuoksi lääkärinhoitoon ehkäisyohjelman jälkeisen vuoden aikana kuin nämä lääkkeet lopettaneet koeryhmän jäsenet. Johtopäätöksenä voidaan todeta, että psyykenlääkkeiden tunnistaminen kaatumisten vaaratekijäksi oli puutteellista. Niiden käyttöön tulisi kiinnittää enemmän huomiota, ja niiden käyttö tulisi purkaa aina, kun se on lääketieteellisesti mahdollista. Kaatumisten ehkäisy pitäisi kuulua terveydenhoitoon. Kohdennettuja ehkäisyohjelmia erilaisille kaatumisvaarassa oleville iäkkäille tulee kehittää edelleen.

Emergência de plântulas de Butia odorata (Barb. Rodr.) Noblick em casa de vegetação

Butia odorata é uma palmeira nativa do Rio Grande do Sul, Brasil, cujos frutos são utilizados na alimentação humana. O objetivo deste estudo foi testar a emergência de plântulas de B. odorata em casa de vegetação a partir de sementes e diásporos submetidos a diferentes procedimentos de superação de dormência. A escarificação através da abertura da cavidade embrionária das sementes permitiu emergência de 72%, com tempo médio de 56 dias. A imersão dos diásporos em água por 18 h antes da semeadura favoreceu a emergência, porém o tempo médio atrasou para 323 dias. Sementes isoladas do endocarpo, porém não escarificadas, apresentaram 38% de emergência, com tempo médio de 319 dias. A emergência a partir de diásporos submetidos a 40 ºC por três semanas antes da semeadura não diferiu da emergência de sementes isoladas do endocarpo; no entanto, o tempo médio foi reduzido de 319 para 206 dias. A abertura da cavidade embrionária possibilitou o maior percentual de emergência de plântulas e menor tempo médio de emergência.

POPULATION STRUCTURE AND PRODUCTION OF COPAIBA OLEORESIN BETWEEN VALLEYS AND HILLSIDES OF THE MINING AREA OFTROMBETAS RIVER - PARÁ1

ABSTRACT We aimed in this work to study natural populations of copaiba (Copaifera multijuga Hayne) on the Monte Branco mountain at Porto Trombetas-PA, in order to support sustainable management and the exploitation of oleoresin from copaiba. We studied the population structure of copaiba on hillsides and valleys of the south face of Monte Branco, within Saracá Taquera National Forest, where bauxite ore was extracted in the biennium 2013-2014 by Mineração Rio do Norte (MRN). We produced a 100% forest inventory of the specie and of oleoresin extraction in order to quantify the potential production of the remaining area. The density of copaiba individuals with DBH > 30 cm was 0.33 individuals per hectare in the hillside and 0.25 individuals per hectare in the valley. Both environments presented a density of 0.28 individuals per hectare. The average copaiba oleoresin yield was 0.661±0.334 liters in the hillside and 0.765±0.280 liters in the valley. The average value of both environments together (hillside and valley) was 0.714±0.218 liters. From all individuals with DBH over 30 cm, 38 (58%) produced some amount of oleoresin, averaging 1.113±0.562 liters in the hillside, 1.329±0.448 liters in the valley and 1.190±0.355 liters in both environments together. The results show the need for planning the use of the surroundings of the study area in order to reach the required volume of copaiba to make feasible the sustainable management of oleoresin extraction in the region.

Vääräkosken kartonkitehdas : Sata vuotta ähtäriläistä pahvia

Ähtärissä Hyvölänjoen varrella oleva Vääräkoski oli teollisen toiminnan keskuksena pyöreät sata vuotta. Kosken partaalle vuonna 1898 perustetun kartonkitehtaan toiminta päättyi vararikkoon vuonna 1998. Vääräkosken kartonkitehdas luokiteltiin valtakunnallisesti arvokkaaksi kulttuurihistorialliseksi ympäristöksi Museoviraston ja ympäristöministeriön julkaisemassa selvityksessä ”Rakennettu kulttuuriympäristö” (1993). Tehtaan rakennukset ja laitteet suojeltiin rakennussuojelulailla vuonna 2002. Siirtyminen lumpun käytöstä puumassaan merkitsi metsäteollisuuden murrosta 1860-luvulla myös Suomessa. Muutos merkitsi puuhiomoteollisuuden syntymistä. Pahvinvalmistusteknologia kehittyi 1890-luvun lopulla teknisten keksintöjen seurauksena. Käsityövaltaisesta, monta erillistä vaihetta vaatineesta pahvin valmistuksesta voitiin siirtyä koneelliseen prosessiteollisuuteen. Ensimmäinen kartonkikone hankittiin Saksasta 1897 Inkeroisten tehtaalle. Vääräkosken kartonkitehtaalle vuonna 1901 tilattu kartonkikone oli järjestysnumeroltaan viides Suomessa. Vääräkosken kartonkitehdas oli maan mittakaavassa pieni ja sen toiminta pysyi suunnilleen samansuuruisena aina päättymiseensä asti. Tuotanto keskittyi kartonkiin, jota tehtaan ainoa kartonkikone valmisti 1000–4000 tonnia vuodessa. Vääräkosken tehdasympäristön arvo perustuu monipuolisuutensa säilyttäneeseen tehdaskokonaisuuteen, lähes alkuperäisinä säilyneisiin rakennuksiin ja laitteisiin, joista kartonkikone on teollisuushistoriamme ainoita yli satavuotiaita. Tämä inventointiraportti julkaistaan, jotta Vääräkosken kartonkitehtaasta jäisi edes jotakin luettavaa historian kirjoihin.
