The Connectivity of Musical Aptitude and Foreign Language Learning Skills: Neural and Behavioural Evidence

Given the structural and acoustical similarities between speech and music, and possible overlapping cerebral structures in speech and music processing, a possible relationship between musical aptitude and linguistic abilities, especially in terms of second language pronunciation skills, was investigated. Moreover, the laterality effect of the mother tongue was examined with both adults and children by means of dichotic listening scores. Finally, two event-related potential studies sought to reveal whether children with advanced second language pronunciation skills and higher general musical aptitude differed from children with less-advanced pronunciation skills and less musical aptitude in accuracy when preattentively processing mistuned triads and music / speech sound durations. The results showed a significant relationship between musical aptitude, English language pronunciation skills, chord discrimination ability, and sound-change-evoked brain activation in response to musical stimuli (durational differences and triad contrasts). Regular music practice may also have a modulatory effect on the brain’s linguistic organization and cause altered hemispheric functioning in those who have regularly practised music for years. Based on the present results, it is proposed that language skills, both in production and discrimination, are interconnected with perceptual musical skills.

A long way to the rainbow country : understanding the foreign market expansion process of Finnish corporations into the Republic of South Africa between 1999 and 2005

De afrikanska ekonomierna växer med nära fyra procent per år och detta är en god indikation på kontinentens växande betydelse. Under kalla kriget hade afrikanska regeringar haft ett begränsat utrymme för opportunistisk köpslående, och därmed även en marginal att positionera sig strategiskt. Alltför ofta uppmuntrade och beskyddade stormakterna diktatorer och små lokala eliter som främst ville berika sig själv. I och med att globaliseringen tog fart och USA allt mera kom att dominera globalt, började en ny era i fråga om förändringar. Trots dessa förändringar på den globala arenan, har Afrika som kontinent hamnat i bakgrunden och jämfört med andra utvecklingsländer har Afrika attraherat ett fåtal utländska investeringar. Fortfarande, speciellt i Norden, finns det lite kunskap om hur utländska företag expanderar sin affärsverksamhet på den afrikanska kontinenten. Det råder brist på empiriska undersökningar om vilken inverkan afrikanska institutionella förändringar och lokala affärsmiljöer har på internationaliseringen och på de utländska företagens affärsutvecklingsstrategier på den afrikanska kontinenten. Med denna avhandling vill jag lyfta fram ett exempel på ett land (Sydafrika), som har lyckat dra nytta av de förändringar som 1990-talet förde med sig. I denna avhandling har jag intervjuat olika personer i ledande positioner inom olika finländska företag i Finland och i Sydafrika. Avhandlingen skapar en referensram för att öka förståelse och fördjupa analys av hur en kombination av olika interna och externa resurser ökar företagens konkurrenskraft och på det sättet bidrar till en framgångsrik affärsutveckling i Afrika. De politiska och sociala aktörerna samt aktörerna inom affärslivet besitter resurser som ambitiösa företag kan dra nytta av i sin strävan att erövra de nya framgångsrika marknaderna i Afrika. Gradvis ökar finländska företag sina insatser på den afrikanska kontinenten i strävan att skapa mervärde för sina kunder. Den värdeskapande processen gör att parterna måste närma sig varandra utgående från sina egna strategiska målsättningar. Hittills har finländska företag varit intresserad att sälja till Afrika men inte intresserad att köpa därifrån. Förutom de praktiska råden till olika företag, föreslår avhandlingen hur den finska staten och den sydafrikanska staten kunde agera tillsammans för att främja ömsesidigt handelsutbyte.

Unintentionally retained foreign bodies after surgical procedures. Analysis of 4547 cases

Objective: this study aims to explore the experience of Brazilian surgeons on Unintentionally Retained Foreign Bodies (RFB) after surgical procedures. Methods: A questionnaire was sent to surgeons by electronic mail, between March and July 2012. The questions analyzed their experience with foreign bodies (FB), foreign bodies' types, clinical manifestations, diagnoses, risk factors and legal implications. Results: in the 2872 eligible questionnaires, 43% of the surgeons asserted that they had already left FB and 73% had removed FB in one or more occasions, totalizing 4547. Of these foreign bodies, 90% were textiles, 78% were discovered in the first year and 14% remained asymptomatic. Among doctors with less than five years after graduation, 36% had already left a FB. The most frequently surgical procedures mentioned were the elective (57%) and routine (85%) ones. Emergency (26%), lack of counting (25%) and inadequate conditions of work contributed (12.5%) to the occurrence. In 46% of the cases patients were alerted about the FB, and 26% of them sued the doctors or the institution. Conclusions: challenging medical situations, omission of security protocols and inadequate work conditions contributed to RFB. However, RFB occurs mostly in routine procedures such as cesarean or cholecystectomy, and at the beginning of the professional career, highlighting, particularly in poorest countries, the need for primary prevention. Textiles predominated causing clinical repercussions and they were diagnosed in the first postoperative months. Surgeons were sued in 11.3% of the RFB cases.

Exchange rate volatility and the use of foreign currency derivatives: Impact of 2008 global financial crisis

This thesis examines the impact of foreign exchange rate volatility to the extent of use of foreign currency derivatives. Especially the focus is on the impacts of 2008 global financial crisis. The crisis increased risk level in the capital markets greatly. The change in the currency derivatives use is analyzed by comparing means between different periods and in addition, by linear regression that enables to analyze the explanatory power of the model. The research data consists of financial statements figures from fiscal years 2006-2011 published by firms operating in traditional Finnish industrial sectors. Volatilities of the chosen three currency pairs is calculated from the daily fixing rates of ECB. Based on the volatility the sample period is divided into three sub-periods. The results suggest that increased FX market volatility did not increase the use foreign currency derivatives. Furthermore, the increased foreign exchange rate volatility did not increase the power of linear regression model to estimate the use foreign currency derivatives compared to previous studies.

Iran's domestic and foreign policies

Iran has a reputation of being a problematic country. Right now, it is proceeding with its nuclear program despite the opposition of the West and neighboring countries and the massive sanctions inflicted upon it. The country is also struggling with domestic issues. Half of Iran’s population belongs to different ethnic or religious minorities. They have poor rights to express their culture in the country, which is a cause of dissatisfaction among non-Shiite and non-Persian citizens. After the Arab Spring, the situation in Iran is getting more topical than ever. In the Syrian conflict, the Shiite Iran is constantly giving support to al-Assad’s regime. These are all factors that have aggravated the already irritated relations between Iran and the West.

Persistence of the biocide activity of atrazine in soils of the southeast of Buenos Aires Province

Atrazine persistence in soils of the southeast of Buenos Aires Province, was studied by an oat bioassay. Atrazine doses of 0.58, 1.16, and 2.32 mg.g-1 dry soil weight (DSW) were applied to pots containing soils from Balcaree, A. Gonzáles Chaves and San Cayetano sites, whose organic matter (OM) content of soils were 5.70, 5.15, and 3,84%, respectively. Avena sativa cv. Millauquén plants were grownth in the pots under greenhouse conditions at different times after atrazine application. Shoots were evenly cut above the soil and dry weight determined as a measure of plant growth. Plants grown in non-sprayed soil were used as controls. Relative dry weight (RDW) of shoots was calculated as percentage of control. Atrazine phytotoxicity was expressed in terms of 50 % plant growth reduction (GR50) in the soils under study. Herbicide persistence was expressed in terms of days after treatment (DAT) needed for the plant to achieve 80% of RDW. Atrazine GR50 values of 0.30, 0.64, and 0.90 mg.g-1 DSW in soils from San Cayetano, Balcare and A.G. Chaves, were respectively obtained at 42 DAT. Herbicide persistences at the recommended dose (1.16 mg.g-1) were 100, 143, and 221 DAT for A.G. Chaves, Balcarce and San Cayetano soils, respectively. San Cayetano soil had both the lowest OM content and cation exchange capacity (CEC), as well as the highest pH, of all the soil studied here. These results were consistent with both the lowest GR50 and the highest persistence abtained for atrazine in this soil.

Critical period for weed control in potatoes in the Huambo Province (Angola)

The effects of different weed management periods on potatoes were studied in three areas (Bailundo, Chianga and Calenga) of the central highlands of Angola and in three cropping seasons, from June 2005 to May 2007. Six weed-management treatments were used to identify critical periods of competition and to allow the development of more precise management recommendations. Total potato yield ranged from about 22 t ha-1 in weed-free plots to about 3 t ha-1 with no weed control a yield loss of 86%. Major weed species Galinsoga parviflora, Cyperus esculentus, Bidens biternata, Amaranthus hybridus, Nicandra physaloides, Portulaca oleracea and Datura stramonium differed from area to area. The species G. parviflora dominated the weed flora in all three areas 73, 97 and 72 plants m² 50 days after crop emergence in Bailundo, Chianga and Calenga respectively, in dry season trials; while C. esculentus was also present in Chianga and Calenga, with an average density of ca 30 plants m-2 in dry season trials. Gompertz and logistic equations were fitted to data representing increasing periods of weed-free growth and weed interference, respectively. Critical periods for weed control, with a 95% weed-free total yield, were estimated from 26 to 66 and from 20 to 61 days after emergence for the rainy and dry seasons, respectively. Weed competition before or after these critical periods had negligible effects on crop yield.
