Tropical biodiversity: has it been a potential source of secondary metabolites useful for medicinal chemistry?

The use of natural products has definitely been the most successful strategy in the discovery of novel medicines. Secondary metabolites from terrestrial and marine organisms have found considerable use in the treatment of numerous diseases and have been considered lead molecules both in their natural form and as templates for medicinal chemistry. This paper seeks to show the great value of secondary metabolites and emphasize the rich chemical diversity of Brazilian biodiversity. This natural chemical library remains understudied, but can be a useful source of new secondary metabolites with potential application as templates for drug discovery.

CASOS INVESTIGATIVOS E A RELAÇÃO COM O SABER: TRAJETÓRIA E PROCESSO DE APRENDIZAGEM DE ESTUDANTES DO ENSINO SUPERIOR NO TOCANTINS

In light of the theory of relationship with know of Bernard Charlot, aiming to understand the unique stories of the subject through a positive lecture, i.e., understanding the reality and the way the subjects read and interpret the world, this article attempts identify how higher education students solve an investigative case and learn the scientific knowledge using this theory. For this, we used narrative as a discourse genre to collect the data of 34 students who participated in the small group activities. After content analysis, the results showed that all groups of students solve the case in a similar way and in three stages, prevailing relations with know with the world, with others and with yourself. However, even if the resolution is similar, chemical learning differs between different groups and differs between the scientific content present in the case. From these results it is possible to identify the effectiveness of learning depends on the epistemic and identity relationships with know of each subject (relationship with yourself) because to learn the student must enter into an intellectual activity (investigative case), stay on it and develop the relationships with known necessary to master the normativity (chemical language).

Is it necessary to soak rice grains to prepare Rhizoctonia solani AG-4 inoculum?

A study was conducted to evaluate the effects on the development of root rot on common bean, cv. 'Dufrix' after treatment with four volumes of water (0, 30%, 60%, and 90%, v/w) added to rice grains previously immersed in water for 24 hours before autoclaving and colonization of grains by Rhizoctoniasolani AG-4. Colonized rice grains and non-infested rice grains were mixed in pots with sterilized soil and sand (2:1), where beans were sown. Based on results of area under plant emergence curve, plant height, plant dry weight, and disease severity, we conclude that inoculum is more effective in causing disease when no water is added to the rice grains before autoclaving.

Monikanavaisen kriisiviestintämallin kehittäminen, asiakasyrityksenä Medi-IT Oy

Tämän diplomityön tavoitteena oli selvittää, mitä asioita organisaation tulisi huomioida tehokkaan, monikanavaisen kriisiviestintämallin suunnittelussa ja toteuttamisessa. Asiakasyritys Medi-IT Oy tukee terveydenhuollon ja sosiaalitoimen palveluntuottajien toimintaa tarjoamalla ja tuottamalla asiantuntija- ja tietotekniikkapalveluita. Tutkimuksessa keskitytään yrityksen tukipalveluyksikköön ja viestinnän lajeista häiriötilanteiden viestintään. Kriisiviestintämalli voidaan tarvittaessa lanseerata myös muihin yksiköihin. Medi-IT Oy:n kriisiviestintämallin kehittäminen aloitettiin kartoittamalla nykytilaa. Tämä tehtiin yrityksen nykyisiä toimintatapoja selvittämällä ja kysymällä asiakkaiden ja työntekijöiden mielipiteitä ja kokemuksia. Viestintään liittyvän puhelinkyselyn asiakkaille suoritti InnoLink-yritys. Kyselyn tuloksista nousi esiin viestinnän ongelmakohtia. Näihin paneutumalla löydettiin kehitettävät kohteet. Nämä kriisiviestinnän ja samalla tapahtumien hallinnan kehityskohteet on esitetty toimintojen tarkennuksina. Asiakasyritys on panostamassa prosessien laatuun ja on aloittamassa ITIL:in hyödyntämisen prosessien läpikäymisessä. Siksi myös ITIL:in periaatteita otettiin huomioon tässä kriisiviestinnän prosessimallissa. Työssä selvitettiin teoriakatsauksen pohjalta, mitkä ovat hyvän kriisiviestinnän ominaisuudet ja mitkä ovat monikanavaisuuden asettamat haasteet, edut ja haitat. Prosessin mallintamisessa käytettiin tapahtumien hallintaan keskittyvää työkalua. Työn lopputuloksena syntyi asiakasyritykselle monikanavaisen kriisiviestinnän kehittämismalli sekä kehittämistä vaativien toimintojen tarkennukset. Työhön sisältyy myös tulevaisuuden kriisiviestinnän prosessimalli, jonka toteutuminen ei ole vielä teknisesti täysin mahdollista.

Is it possible to utilize VIX for a profitable trading strategy of S&P 500 Index?

The goal of this research was to make an overall sight to VIX® and how it can be used as a stock market indicator. Volatility index often referred as the fear index, measures how much it costs for investor to protect his/her S&P 500 position from fluctuations with options. Over the relatively short history of VIX it has been a successful timing coordinator and it has given incremental information about the market state adding its own psychological view of the amount of fear and greed. Correctly utilized VIX information gives a considerable advantage in timing market actions. In this paper we test how VIX works as a leading indicator of broad stock market index such as S&P 500 (SPX). The purpose of this paper is to find a working way to interpret VIX. The various tests are made on time series data ranging from the year 1990 to the year 2010. The 10-day simple moving average strategy gave significant profits from the whole time when VIX data is available. Strategy was able to utilize the increases of SPX in example portfolio value and was able to step aside when SPX was declining. At the times when portfolio was aside of S it was on safety fund like on treasury bills getting an annual yield of 3 percent. On the other side just a static number’s of VIX did not work as indicators in a profit making way.

Asymmetriskt påverkat beslutsfattande i IT-projekt

I avhandlingen beskriver Leif Marcusson vad som påverkar beslutsfattare då dessa ska fatta beslut i IT-projekt. Arbetet har mynnat ut i en modell, som beskriver asymmetrisk påverkan på beslutsfattande. Eftersom modellen är både deskriptiv och normativ kan den användas för att beskriva och för att styra beslutsfattande. Ett beslut fattas av en eller flera personer i en viss situation, där det även krävs att det finns ett beslutsunderlag. Beslutet påverkas av en mängd olika faktorer - allt från väder till ekonomi. De olika faktorerna är indelade utifrån om de påverkar beslutsunderlaget, individen eller beslutssituationen. Dessa tre delar innehåller i sig ett antal faktorsgrupper. Den första delen, Underlag, innehåller två faktorsgrupper: den ena beskriver underlagets tydlighet och den andra beskriver effekten och nyttan av det fattade beslutet. Den andra delen, Individ, innehåller fyra faktorsgrupper. Dessa beskriver det som skapat individen, det som påverkar individen, det som påverkar individens framtid och det som påverkar gruppen. Den sista delen, Situation, innehåller två faktorsgrupper, som beskriver det som styr situationen och det som påverkar den. Var och en av dessa faktorsgrupper består av ett antal faktorer, som i sin tur kan delas in i delfaktorer osv. Det finns med andra ord närapå oändligt många faktorer, som kan påverka den som ska fatta ett beslut. Förståelse för och insikt i modellen kan underlätta för beslutsfattare. Modellen är förvisso skapad för IT-projekt, men den går även att använda i andra projekt och i linjeverksamhet.

Den talande bokens poetik : en studie med fokus på olika unga vuxnas reception av tre fiktiva texter inlästa på band

The purpose of the research project The poetics of the talking book is to contribute to the knowledge about patterns of understanding in young adults’ reception of fiction, which they listened to through audio books. The problem explored was: How do different groups of listeners receive fictive text presented as a talking book with variations regarding use of voice, engagement and sound effects? The problem formulation rendered four specific research questions: 1. What patterns can be identified in the listeners’ answers regarding story structure and cognitive content in a comparative perspective comprising different reading styles in the taped versions of the text? 2. What patterns of understanding in interpretative reading can be identified in different listeners? 3. Which thoughts do the listeners have about what the talking book should sound like? 4. What affordances for young adults with the functional disability of mild mental retardation can be made visible through guided literature conversations? The theoretical frame of reference was formed by text–reader-oriented literary theory, psychological schema theory, and research regarding voice quality and communication. The project was carried out in two steps. The first phase was to produce the audio books with two variations of reading practice of three short stories with an existential theme in each text. The second step comprised interviewing of 32 young adults (a special group with a reading handicap in form of mild mental retardation, and a reference group with no handicap). The interviews formed as literary conversation were carried out three times during one year. The phenomenological-hermeneutic approach focused on the life worlds of the participants as meaning seeking beings. The analysis was carried out using method triangulation, mainly using phenomenological meaning concentration. The double hermeneutics in use when interpreting the interpretations of the participants revealed a capacity for aesthetic reading of fiction in the special group as well as in the reference group. The aesthetic qualities were found sufficient in all variations of reading by the professional readers of the audio book they listened to. The young adults also could describe how they wanted the audio book to sound: just as if you were reading yourself. A model describing the analytical steps and concepts in use was a result that can serve as an outline of a poetics for the talking book. Unexpected research results were how important the guided literary conversation turned out to be in order to realise the affordances given by the texts regarding exploration of existential themes in the young adults’ life worlds. Thus the result of the research project can be positioned as a piece of emancipatory research stressing the importance of including this group of young adults in the society’s conversation about culture and meaning.
