Varastonohjauksen menetelmät ja niiden käyttö osana yrityksen kannattavuuden hallintaa

Tutkielman tavoitteena on tuottaa kohdeyrityksessä tietoa, joka auttaa tunnistamaan ja soveltamaan kannattavuuden parantamiseen vaikuttavia varastonohjauksen menetelmiä ja tukee varastonohjausta koskevaa päätöksentekoa. Varastonohjauksella tarkoitetaan varastoihin sitoutuneen pääoman hallintaa ja materiaalivirtojen ohjausta. Varastonohjauksen ensisijainen tavoite on saavuttaa optimaalinen tasapaino halutun asiakaspalvelutason ja varastonpidosta aiheutuvien kustannusten välillä. Tutkielma toteutettiin tapaustutkimuksena. Aineistona käytettiin kohdeyrityksen sisäisiä tietoja. Varastonohjausperiaatteiden kohdentamiseksi varastonimikkeet luokiteltiin ABC-analyysin avulla, jota täydennettiin kriittisyysanalyysillä. Ohjausmenetelmät määriteltiin luokittain. Varastoilla on merkittävä rooli yrityksen toiminnassa. Niihin sitoutuu pääomaa, joka vaikuttaa yrityksen kannattavuuteen. Nimikkeiden luokittelu ja luokkakohtaisten ohjausmenetelmien ja -periaatteiden määrittely on erittäin tärkeää. Varastotasojen alentamisella ja varaston kiertonopeuden nostamisella on kannattavuutta parantava vaikutus.

Neuronal activity controls the antagonistic between PGC-1α and SMRT in regulating antioxidant defences

Transcriptional coactivators and corepressors often have multiple targets and can have opposing actions on transcription and downstream physiological events. The coactivator peroxisome proliferator-activated receptor-γ coactivator (PGC)-1α is under-expressed in Huntington's disease and is a regulator of antioxidant defenses and mitochondrial biogenesis. We show that in primary cortical neurons, expression of PGC-1α strongly promotes resistance to excitotoxic and oxidative stress in a cell autonomous manner, whereas knockdown increases sensitivity. In contrast, the transcriptional corepressor silencing mediator of retinoic acid and thyroid hormone receptors (SMRT) specifically antagonizes PGC-1α-mediated antioxidant effects. The antagonistic balance between PGC-1α and SMRT is upset in favor of PGC-1α by synaptic activity. Synaptic activity triggers nuclear export of SMRT reliant on multiple regions of the protein. Concommitantly, synaptic activity post-translationally enhances the transactivating potential of PGC-1α in a p38-dependent manner, as well as upregulating cyclic-AMP response element binding protein-dependent PGC-1α transcription. Activity-dependent targeting of PGC-1α results in enhanced gene expression mediated by the thyroid hormone receptor, a prototypical transcription factor coactivated by PGC-1α and repressed by SMRT. As a consequence of these events, SMRT is unable to antagonize PGC-1α-mediated resistance to oxidative stress in synaptically active neurons. Thus, PGC-1α and SMRT are antagonistic regulators of neuronal vulnerability to oxidative stress. Further, this coactivatorcorepressor antagonism is regulated by the activity status of the cell, with implications for neuronal viability.

Kansallisten immateriaalioikeuksien vaikutus lääkekeksintöihin Suomessa ja Ruotsissa 1980-90-luvulla

Pro gradu- tutkielman tarkoituksena oli tutkia lääkkeiden immateriaalioikeudellisia suojamuotoja Suomen ja Ruotsin osalta. Tutkimuksessa pyrittiin selvittämään lääkkeiden kansallisen patenttisuojan, lisäsuojatodistuksen ja dokumentaatiosuojan vaikutusta lääkekeksintöihin 1980–90-luvun Suomessa ja Ruotsissa. Lääkkeiden lisäsuojatodistuksella tarkoitetaan ainoastaan lääkeaineille tarkoitettua erillistä immateriaalioikeudellista lisäsuojamuotoa, joka pidentää suoja-aikaa enimmillään viidellä vuodella. Dokumentaatiosuojalla tarkoitetaan suojamuotoa, joka suojaa lääkkeiden kehittämisessä aikaan saatuja tutkimus- ja turvallisuustuloksia rinnakkaisvalmistajilta tietyn määritellyn ajan. Suomen ja Ruotsin kansallisessa lainsäädännössä oli tarkasteluajanjaksolla olennaisia eroja. Rinnakkaisongelmana tutkittiin innovaatio- ja patenttipolitiikan merkitystä lääkekeksintöjen määrään ja laatuun. Tutkimuskysymyksiä lähestyttiin virallislähteiden ja kirjallisuuden lisäksi myös teemahaastatteluin. Haastateltavat olivat alan asiantuntijoita. Tutkimus oli haasteellinen. Oli palkitsevaa saada asiaa koskeva ”hiljainen tieto” kansiin. Suomen ja Ruotsin poliittinen ja lainsäädännöllinen ilmapiiri poikkesivat toisistaan. Suomessa vallitsi protektionistinen ilmapiiri ja se näkyi politiikassa ja vaikutti lainsäädäntöön. Menetelmäpatentista ei haluttu luopua. Menetelmäpatentti on patentti, joka käsittää ainoastaan lääkeaineen valmistusmenetelmän, eikä lopputuotetta. Suomessa sallittiin lääkeaineiden tuotepatentti vasta 1995. Toisin oli Ruotsissa; siellä poliittinen ilmapiiri ja valtion sekä lääketeollisuuden näkemykset johtivat kehitystä niin, että tuotepatenttikielto poistettiin huomattavasti aiemmin kuin Suomessa. Ruotsi oli kaukonäköisempi myös muiden suojamuotojen kohdalla. Lopputuloksena tästä seurasi se, että Ruotsin lääketeollisuus on menestynyt huomattavasti paremmin kuin Suomen. Lääkekeksintöjä tehtiin enemmän. Ruotsin lääkekeksinnöistä suuri osa oli uusia molekyylejä; Suomen vastaava osuus oli selvästi pienempi. Myös Ruotsin lääkevienti oli ja on huomattavasti suurempaa kuin Suomen.

On Fault Tolerance Methods for Networks-on-Chip

Technology scaling has proceeded into dimensions in which the reliability of manufactured devices is becoming endangered. The reliability decrease is a consequence of physical limitations, relative increase of variations, and decreasing noise margins, among others. A promising solution for bringing the reliability of circuits back to a desired level is the use of design methods which introduce tolerance against possible faults in an integrated circuit. This thesis studies and presents fault tolerance methods for network-onchip (NoC) which is a design paradigm targeted for very large systems-onchip. In a NoC resources, such as processors and memories, are connected to a communication network; comparable to the Internet. Fault tolerance in such a system can be achieved at many abstraction levels. The thesis studies the origin of faults in modern technologies and explains the classification to transient, intermittent and permanent faults. A survey of fault tolerance methods is presented to demonstrate the diversity of available methods. Networks-on-chip are approached by exploring their main design choices: the selection of a topology, routing protocol, and flow control method. Fault tolerance methods for NoCs are studied at different layers of the OSI reference model. The data link layer provides a reliable communication link over a physical channel. Error control coding is an efficient fault tolerance method especially against transient faults at this abstraction level. Error control coding methods suitable for on-chip communication are studied and their implementations presented. Error control coding loses its effectiveness in the presence of intermittent and permanent faults. Therefore, other solutions against them are presented. The introduction of spare wires and split transmissions are shown to provide good tolerance against intermittent and permanent errors and their combination to error control coding is illustrated. At the network layer positioned above the data link layer, fault tolerance can be achieved with the design of fault tolerant network topologies and routing algorithms. Both of these approaches are presented in the thesis together with realizations in the both categories. The thesis concludes that an optimal fault tolerance solution contains carefully co-designed elements from different abstraction levels

Conversioni al cattolicesimo a Roma tra Sei e Settecento. La presenza degli scandinavi nell’Ospizio dei Convertendi.

In my PhD dissertation, I have examined a group of people of Scandinavian origin received by Ospizio dei Convertendi. This group has been hitherto largely unknown to historical research. The Ospizio was an institute founded by the Oratorian Congregation in Rome in 1673 to provide religious instruction and material aid to both recent and aspirant converts to Roman Catholicism. My research traces the profile of converts and a typology of motives, examining different factors which influenced the conversion process. I show that the key factors were often of a social rather than a religious nature. Moreover, I have analyzed the hospice in the context of Counter-Reformation charity as well. In terms of numbers, the Scandinavians formed a somewhat marginal yet not insignificant group within the Roman hospice. Out of a total of 2203 guests received between 1673 and 1706, 4.6 % were Scandinavians: 74 Swedes (including Finland and Livonia) and 27 Danes (including Norway). They came from a rigorously Protestant region which reacted to Catholicism with severe legislative measures. Converts to Catholicism risked confiscation of their goods, expulsion or even capital punishment. Since both Sweden and Denmark were practically impenetrable to Catholicism at the time and clandestine missionary attempts often failed before they had even properly started, the Roman Catholic Church shifted its interest towards Northerners arriving in Rome, a preferred destination for young noblemen, artists and migrant craftsmen. The material related to Ospizio dei Convertendi, conserved in the Vatican archives, is a scarcely known yet unusually rich source, not only for the religious history of our continent, but also for social history and the study of migration in early modern Europe. It contains a wealth of information about members of the subordinate classes, of their travels and lives in Europe. The profile delineated in these documents is of individuals who had a wide range of different professions and different aspirations. These documents encompass a vast social spectrum that was highly mobile on a continent which by that time had become pluriconfessional. Therefore, these migrants faced the complex religious reality in their everyday life. The principal corpus of my research consists of two types of manuscript sources created for administrative and in a way also for apologetic purposes of the Roman Catholic Church. My starting point is the Primo registro generale of Ospizio dei Convertendi. This is a volume in which the following information about each guest was registered: name, nationality, city of origin, age, sex, profession, confession professed before converting, date of arrival, departure, abjuration and baptism. Typically, the convert was male, originating from Stockholm or Copenhagen, from 21 to 30 years of age. The biggest occupational groups in descending order were soldiers, noblemen, craftsmen and sailors. Thus the data reflects a multiform reality of interurban and long distance migration, ideals regarding the education of young noblemen and gentry as well as the need of European armies to hire foreign mercenaries in their various campaigns. Against this background the almost total absence of women is hardly surprising: there is only one woman in the material I have studied. The second main source, Nota degl’ospiti ricevuti e spese fatte per essi, sheds more light on the choices of the converts, their motivations and their lives outside Scandinavia before reaching Rome. This narrative material permits an analysis which completes but also goes far beyond the columns of the Institute’s general register. This material consists of reports written by Catholic priests based on an interview conducted upon each guest’s arrival. The material frequently includes information on what the converts would do following their departure from the Institute as well. These sources have a specific narrative form and contain short biographies, list reasons for converting and information about the journey from the North to the Mediterranean - a journey which in many cases took several years. Moreover, they show that certain unorthodox practices such as calling on the saints and pleading for help from them were not uncommon in the Protestant popular religion. The recording of information on conversions from Protestantism to Catholicism reflects both religious and social interest on the part of the receiving institute. The information obtained was used for the purposes of religious teaching, for finding adequate ways of inserting the convert into Italian society so that he could earn a living, and to find effective methods to convert others with a similar cultural and geographical background. The stories recorded were based on interviews with the newly-arrived, information obtained from a travel companion or fellow countrymen, or from written documents the aspirant converts carried with them. These sources illustrate, although sometimes in rather simplified ways, the circumstances and motivations which were relevant to the choice of changing one’s confession. In addition, I have examined petitions addressed to the hospice and other Roman authorities in order to get financial aid. These petitions were written by Italian scrittori, and they contain certain conventions and topoi of presenting the conversion with the purpose of improving the chances of obtaining financial aid. It is through these filters, which may seem initially almost invisible, that the remote voice of the converts reaches us. The results of the analysis are particularly interesting because they disagree with some of the principal conclusions of previous work on the subject. First, earlier research has focused almost exclusively on the conversions of noblemen, and has argued, second, that the Queen Christina of Sweden was the driving force behind their change of confession. The sources examined for this dissertation present a profile of long-distance migrants, many of them members of the subordinate classes, who were looking for ways to make their living in Europe. These people had in many cases left their country of origin several years earlier and not for religious reasons, so, crucially, we are not dealing with confessional migration in these cases. Rather, conversion was a complex process, intricately tied up with strategies of survival, integration and upward social mobility. At the same time, while these components are significant on their own right, they do not necessarily point to the absence of motivations of a more clearly religious nature.

RFID tekniikan käyttömahdollisuudet betonituoteteollisuuden varastonhallinnassa

Lujabetoni Oy:n kappaletavaran varastonhallinnassa on todettu paljon kehitettävää. Kappaletavaran varasto-otot eivät perustu todellisiin määriin, varastonkierto on hidasta, varastointi sitoo paljon pääomaa ja inventointi on työlästä. Tähän ongelmaan haetaan ratkaisua RFID –teknologiasta. Työn teoriaosassa on käsitelty RFID –teknologian teoriaa ja nykytilaa, sekä varastoinnin peruskäsitteitä ja varastonohjausmenetelmiä. Empiirisessä osassa on laadittu RFID –järjestelmän toteutussuunnitelma. Työn tuloksena on RFID –järjestelmän kuvaus sekä toteutussuunnitelma, joilla saavutetaan tavoitellut hyödyt. Työssä löydettiin menetelmät joilla komponentit voidaan luotettavasti tunnistaa, sekä suunniteltiin todellisiin tapahtumiin perustuva, automaattiset vastaanotto- ja varasto-otto –kirjaukset mahdollistava RFID –järjestelmä. Näiden ansiosta varastotyö ja varastoihin sitoutuva pääoma vähenevät, jolloin saavutetaan säästöjä varastointikustannuksissa.

Siirtohinnoitteluperiaatteet johtamisen apuvälineenä: case-tutkimus

Tämä tutkimus tarkastelee siirtohinnoittelun periaatteita ja sen taustalla vaikuttavia tekijöitä. Tutkielman tavoitteena on tutkia kohdeyrityksen nykyistä siirtohinnoittelua ja laatia sille periaatteet sen yksiköiden väliselle sisäiselle kaupalle. Tarkoituksena on kehittää siirtohinnoitteluperiaatteet, jotka auttavat johtoa liiketoiminnan eteenpäin viemisessä niin, että nuo periaatteet ovat samalla oikeudenmukaiset kohdeyrityksen eri osapuolille. Tutkimus on luonteeltaan kvalitatiivinen, teoreettinen ja kuvaileva case-tutkimus. Se tuo esille teoriaosuudessa eri siirtohinnoitteluvaihtoehtoja ja pohtii analyyttisesti niiden hyötyjä ja haittoja. Teoriaosuus perustuu kattavalle kirjallisuudelle, jonka avulla otetaan huomioon tekijöitä, jotka vaikuttavat siirtohinnoitteluprosessin taustalla. Tutkielman empiirinen aineisto kerättiin haastattelemalla kohdeyrityksen ylintä johtoa. Haastatteluiden rakenne oli luonteeltaan puolistrukturoitu. Lisäksi käytiin aiheeseen liittyvää keskustelua useaan otteeseen kohde-yrityksen talouspäällikön kanssa sekä tehtiin tutustumiskäynti erääseen osuuskuntaan, jossa kohdeyritys on osakkaana. Vierailu perustui osuuskunnan talouspäällikön pitämään esitykseen ja sen aikana käytyyn keskusteluun. Haastattelut tehtiin kevään 2012 aikana. Tutkimuksen perusteella siirtohinnoittelu on monimutkainen prosessi, jossa samanaikaisesti ei voida saavuttaa kaikkia siltä vaadittuja tavoitteita. Siirtohinnoitteluperiaatteita laadittaessa tulee ottaa etenkin huomioon 1) organisaation liiketoiminnan luonne 2) yksiköiden luonne, 3) vaihdettavien tuotteiden luonne, 4) erilaisten hintojen saatavuus sekä 5) suorituskyvyn mittaus ja arviointi. Tämä tutkimus suosittelee kohdeyrityksen tulos-yksiköille yleisesti mukautetun markkinaperusteisen siirtohinnoittelu-vaihtoehdon käyttöönottoa. Jalostustoimintaa vaativien tuotteiden sisäiselle kaupalle tutkimus suosittelee kustannusperusteisen vaihtoehdon noudattamista.

E-tailer business model creation: an information technology perspective

This research analyzes e-tailer business model formulation and the role of information technology in enabling value creation from the point of view of an e-tailer. The thesis explains the value creation dynamics and the components of an e-tailer business model and further illustrates how information technology enables value creation throughout the different components of e-tailer business models. The theoretical part of the thesis describes the sources of value creation in virtual markets through evaluating the explanatory value of traditional strategic management theories. The theoretical part advances to present an integrated model of the value creation mechanisms in the virtual markets and further describes the components of an e-tailer business model. The role of information technology in e-tailer business models are represented by illustrating how it is able to add value throughout the activities and processes of the e-tailer business model. The empirical descriptive qualitative single-case research focuses on demonstrating how a global retailer of consumer goods operates the different components in its business model. The findings indicate that information technology plays a considerable role in all the components of an e-tailer business model and should not be treated solely as a supporting business function, but rather as one of the most valuable assets in enabling successful e-tailing operations.

Industrial solution business – transition from product to solution offering

The business logic in the manufacturing industry has changed in the 21st century. In the current industrial market, manufacturers are driven to provide more comprehensive offerings that go beyond the traditional product-orientation by providing capacity and availability for their customers. From incidental merchandise, services have become the core of manufacturers’ offerings with long-lasting service agreements over the life-cycles of their products. This change is driven both by the need of providers to grow and gain competitive advantage and by increased customer demand caused by customers’ outsourcing trends. The three key drivers for manufacturers’ service strategies are outsourcing trends, saturation of the installed base, and commoditization in product markets. Thus, manufacturers focus on providing industrial solutions which are delivered through relational processes with customers by using solution-driven business models. In the management of marketing activities, this can be regarded as closer customer relationships, service-dominant business logic, and collaboration in solving customers’ problems. However, there are few studies on comprehensive conceptualizations of a solution offering that include different elements and their roles, especially in the context of capital goods industry. Also the transition process needs further studies in a real life context. This study explores the transition process of an industrial company from product to solution business and, as an aid to managing the solution business, explicates the structure and management of an industrial solution offering. There are two themes, the industrial transition process and industrial solution offering. Regarding the industrial transition process, the aim is to understand the supplier view on the process and its execution and to determine the challenges related to the transition process. The industrial solution offering is discussed by its elements and characteristics, as well as management. Furthermore, a special type of build-own-operate-transfer business model is presented and its suitability in the industrial context analyzed. The study includes findings achieved by qualitative methods and from four case companies. Based on the results, it is tentatively suggested that in the industrial solution business, the transition from product to solution business is not a linear project but an evolving process that varies according to customer needs, which suggests that companies need to possess an ability to develop new business models for different customer needs. The industrial solution offering is dynamic as it evolves in collaboration according to the prevailing and latent customer needs, which suggest restructuring of the organization from a product-centric to a customer-centric one. Furthermore, based on the findings, the concept of industrial solutions is defined as an ongoing relational process to satisfy a customer’s particular business or operational requirements, and the concept of industrial solution offering as an entity comprising the customized goods, services, collaboration, and finance needed to fulfill the industrial solution. Finally, the study offers several managerial implications for industrial managers involved in the transition and management of the solution business and its offering.

Railways, Airports and Sea Container Operators as Publicly Listed Companies – Financial Performance and Shareholder Value Creation Perspective

Logistics infrastructure and transportation services have been the liability of countries and governments for decades, or these have been under strict regulation policies. One of the first branches opened for competition in EU as well as in other continents, has been air transports (operators, like passenger and freight) and road transports. These have resulted on lower costs, better connectivity and in most of the cases higher service quality. However, quite large amount of other logistics related activities are still directly (or indirectly) under governmental influence, e.g. railway infrastructure, road infrastructure, railway operations, airports, and sea ports. Due to the globalization, governmental influence is not that necessary in this sector, since transportation needs have increased with much more significant phase as compared to economic growth. Also freight transportation needs do not correlate with passenger side, due to the reason that only small number of areas in the world have specialized in the production of particular goods. Therefore, in number of cases public-private partnership, or even privately owned companies operating in these sub-branches have been identified as beneficial for countries, customers and further economic growth. The objective of this research work is to shed more light on these kinds of experiments, especially in the relatively unknown sub-branches of logistics like railways, airports and sea container transports. In this research work we have selected companies having public listed status in some stock exchange, and have needed amount of financial scale to be considered as serious company rather than start-up phase venture. Our research results show that railways and airports usually need high fixed investments, but have showed in the last five years generally good financial performance, both in terms of profitability and cash flow. In contrary to common belief of prosperity in globally growing container transports, sea vessel operators of containers have not shown that impressive financial performance. Generally margins in this business are thin, and profitability has been sacrificed in front of high growth – this also concerns cash flow performance, which has been lower too. However, as we examine these three logistics sub-branches through shareholder value development angle during time period of 2002-2007, we were surprised to find out that all of these three have outperformed general stock market indexes in this period. More surprising is the result that financially a bit less performing sea container transportation sector shows highest shareholder value gain in the examination period. Thus, it should be remembered that provided analysis shows only limited picture, since e.g. dividends were not taken into consideration in this research work. Therefore, e.g. US railway operators have disadvantage to other in the analysis, since they have been able to provide dividends for shareholders in long period of time. Based on this research work we argue that investment on transportation/logistics sector seems to be safe alternative, which yields with relatively low risk high gain. Although global economy would face smaller growth period, this sector seems to provide opportunities in more demanding situation as well.

Hankinnan prosessien systemaattinen kehittäminen

Tämän pro gradu -tutkielman tavoitteena oli standardoida ja kehittää hankinnan prosesseja systemaattisesti. Prosessien standardoiminen edesauttaa organisaation itseohjautuvuutta ja parantaa organisaation kyvykkyyttä. Tämä tutkielma tuottaa uutta tutkimustietoa tutkimusaukkoon hankinnan prosessien systemaattisesta kehittämisestä. Tutkielman teoriaosassa käsitellään prosessiajattelua, ISO 9001 standardin vaikutusta hankintatoimintaan, tunnistetaan hankinnan prosesseja ja esitetään erilaisia hankinnan prosesseihin soveltuvia LEAN Six Sigma kehitystyökaluja. Tutkielman empiirinen osio on toteutettu toimeksiantona suurelle teollisuusyritykselle. Tämän tutkielman empiirisessä osiossa on yhdistelty kvalitatiiviselle ja kvantitatiiviselle tutkimukselle ominaisia tutkimusmetodologioita. Tutkimusmetodologioiden yhdisteleminen tuottaa lisäarvoa tutkielman toteutukselle ja parantaa työn luotettavuutta. Tässä tutkielmassa käytetyt tutkimusmenetelmät koostuvat kvantitatiiviselle tutkimukselle ominaisesta kyselystä hankinnan prosessien nykytilan selvittämiseksi sekä kvalitatiivisen tutkimuksen tutkimusmenetelmille ominaisesta tapaustutkimuksesta. Kyselyn avulla muodostettiin analyysi hankinnan prosessien nykytilasta, jonka pohjalta toimeksiantajayritykselle ehdotettiin kehitettäviä hankinnan prosesseja. Lopulliseksi kehityskohteeksi valittu prosessi määriteltiin aivoriihessä kerätyn tiedon perusteella kehityspotentiaalin esille tuovasta nelikentästä. Kehitettävä prosessi asemoitui samalla tapaustutkimuksella tutkittavaksi tapaukseksi. Kehitettäväksi prosessiksi valittiin saapuvan tavaran vastaanotto ja visuaalinen tarkastaminen. Prosessia kehitettiin mallintamalla ja LEAN Six Sigma menetelmiä hyödyntäen. Prosessimallinnuksen sekä LEAN Six Sigma menetelmien tueksi kerättiin tietoa aivoriihistä ja teemahaastatteluista. Tutkielman tuloksena toimeksiantajayritys sai kokonaiskuvan hankinnan prosessien nykytilasta, kehitetyn tavoiteprosessin ja työohjeen saapuvan tavaran vastaanotolle ja visuaaliselle tarkastukselle sekä jatkossa hankinnan prosessien standardoimista ja kehittämistä helpottavan hankinnan prosessin systemaattisen kehittämismallin. Hankinnan prosessin systemaattinen kehittämismalli on uutta tutkimustietoa, joka asemoituu hankinnan prosessien kehittämisen tutkimusaukkoon. Hankinnan prosessin systemaattista kehittämismallia ei tämän tutkielman pohjalta voida yleistää, koska tutkielma on toteutettu toimeksiantajayrityksen lähtökohdista. Johtopäätöksenä voidaan todeta, että toimeksiantajayritys, muut organisaatiot sekä tutkimuskenttä tarvitsevat lisää tietoa hankinnan prosessien kehittämisestä. Hankinnan prosessien kehittämistä tulisi tutkia enemmän ja erityisesti tässä tutkielmassa esitettyä kehittämismallia tulisi jatkossa testata niin, että kehittämismallin toimivuus voitaisiin yleistää.

O mercado brasileiro do século XIX: uma visão por meio do comércio de cabotagem

The Brazilian market in the XIX century: an approach through the cabotage commerce. The maritime commerce consisted of the main way of circulation of the goods between the Brazilian provinces until the second half of century XIX. Although the relatively big importance of the flows of commerce with the exterior, we note significant exchange of goods by sea between the Brazilian regions since the colonial period. A part of these exchanges derived from products destined in last instance to the foreigner or imported of the exterior. However, another part elapsed of national goods that had not arrived at be exported to the international market. Many goods for the colonial and imperial consumption had circulated by the Brazilian coasts in expressive sums. From the information raised for the imperial period, especially the decades of 1860 and 1870, we verify that most of the goods commercialized between the provinces consisted of national products destined to the internal consumption.

The "hot money" phenomenon in Brazil

Because of its high interest rates, Brazil attracts more and more speculative capital flows, called "hot money", under the form of foreign loans, direct or portfolio investments. Actually, the country is directly involved in a carry-trade strategy that tends to appreciate the real, what penalizes the Brazilian exportations of manufactured products. Moreover, capital inflows are extremely volatile, and their departure, causing a fall in loans granted to the Brazilian private banks, could provoke a dangerous burst of the speculative bubble they have contributed to form in the Brazilian real estate sector.

A graphic explanation on how a tax on exports neutralizes the Dutch disease without costs to exporters

The adequate way of neutralizing the Dutch disease is the imposition of a variable tax on the export of the commodity that originates the disease. If such tax is equivalent to the "size" of the Dutch disease, it will shifts to the right its supply curve of the commodity in relation to the exchange rate, giving the existing domestic supply and the international demand, the exchange rate will depreciate at the value of the tax, and the equilibrium exchange rate will move from the "current" to the "industrial" equilibrium.
