Do innovation and human capital explain the productivity gap between small and large firms?

Empirical evidence is compelling that large firms are more productive than small firms. The hypothesis in this paper is that the productivity differences between small and large firms are associated with two of the main determinants of a firm’s performance: the human and technological capital that firms incorporate. We suggest that the contribution of these factors in explaining the productivity-size gap might not only be due to the fact that large firms make a more extensive use of them, but also because large firms obtain higher returns from their investment in human and technological capital. The evidence we obtain for a comprehensive sample of Spanish manufacturing firms (1990-2002) supports this hypothesis, which has important implications for the effectiveness of policies designed to improve productivity in SMEs by stimulating innovation and the use of more skilled workers.

Aplicatiu per gestionar la informació administrativa, tècnica i comptable per una empresa constructora

Les tendencies del mercat actual i futur obliguen a les empreses a ser cada vegada més competitives. Tota empresa que desitgi competir en el mercat actual ha de considerar la informació com un dels seus principals actius. Per aquesta raó, és necessari que l’empresa disposi dels sistemes d’informació adequats per ser gestionada. En les pimes ( petites i mitjanes empreses ), i en la majoria dels casos, la seva informació es troba repartida en diversos aplicatius informàtifcs. Això comporta principalment una duplicitat de dades, costos de manteniment i possibles errades en la informació. Dins del sector de les pimes, es troben empreses contructores d’un volum petit o mig, les quals enmagatzemen molta informació tècnica i de planificació per desemvolupar els seus projectes. Aquesta necessitat els hi suposa, tenir un aplicatiu eficient per la gestió i seguiment de la producció de les seves tasques i per altra banda l’aplicatiu necessari com qualsevol pime a nivell administratiu i comptable. L’objectiu principal d’aquest treball és generar un aplicatiu que integri la informació administrativa, comptable i tècnica per una empresa constructora. Amb l’assoliment d’aquest objectiu l’empresa constructora guanya temps en l’entrada i accés a les dades, evita la seva duplicitat i redueix el seu manteniment. En resum, redueix els costos de l’empresa i augmenta la seva seguretat en la informació. Un el mercat, existeixen aplicatius anomenats ERP ( Enterprise resource planning o sistemes de planificació de recursos ) els quals la seva gran virtud es la integració de les dades. Aprofitant aquests aplicatius i seleccionant-ne el més adequat, s’ha generat la part de gestió i planificació necessària per l’empresa constructora integrant-la i personalitzant-la en els processos existents de l’aplicació ( comptabilitat, ventes, compres, recursos humans, magatzems, etc… ) Entre les conclusions més rellevants obtingudes en aquest treball, voldriem destacar la millora i reducció d’entrada, accés i manteniment de la informació, l’històric que proporciona l’eina i per tan la millora de la gestío i planificació de l’empresa.

Mikroyrittäjä ja yrityksen kasvu

Tämän tutkimuksen tarkoituksena on selvittää mitkä tekijät ovat mikroyrityksen kasvun edellytyksenä ja mitkä tekijät ovat kasvun esteinä. Tutkimuksen taustalla on mikroyritysten yleisesti vähäinen kasvuhalukkuus. Tässä tutkimuksessa yrittäjien kasvuaikomuksia tarkastellaan kasvun prosessimalliin tukeutuen ja mikroyritysten kasvuun vaikuttavia tekijöitä tarkastellaan Perrenin mikroyrityksen kasvuun vaikuttavien tekijöiden mallin avulla. Tutkimuksessa on käytetty kvalitatiivista tutkimusmenetelmää. Tutkimus on toteutettu haastattelututkimuksena, jossa on haastateltu mikroyrittäjiä Päijät-Hämeessä Lahden ja Hollolan alueilla. Tämän tutkimuksen mukaan mikroyritysten kasvuun vaikuttavat yrittäjän tahtotila ja kyky yrityksen kehittämiseen sekä yrittäjän riskinottokyky että suotuisat ympäristölliset olosuhteet. Näiden tekijöiden puuttuminen estää kasvun. Yrityksen kasvua estäviä muita tekijöitä ovat tutkimuksen mukaan mikroyritysten liiallinen paikallisuus, yhteistyön vähäisyys sekä yrittäjän liiallinen kietoutuminen liiketoimintaan että toiminnan liian vähäinen strateginen suunnittelu.

Small and Large Scale Dynamics in the Milky Way

This thesis contains dynamical analysis on four different scales: the Solar system, the Sun itself, the Solar neighbourhood, and the central region of the Milky Way galaxy. All of these topics have been handled through methods of potential theory and statistics. The central topic of the thesis is the orbits of stars in the Milky Way. An introduction into the general structure of the Milky Way is presented, with an emphasis on the evolution of the observed value for the scale-length of the Milky Way disc and the observations of two separate bars in the Milky Way. The basics of potential theory are also presented, as well as a developed potential model for the Milky Way. An implementation of the backwards restricted integration method is shown, rounding off the basic principles used in the dynamical studies of this thesis. The thesis looks at the orbit of the Sun, and its impact on the Oort cloud comets (Paper IV), showing that there is a clear link between these two dynamical systems. The statistical atypicalness of the orbit of the Sun is questioned (Paper I), concluding that there is some statistical typicalness to the orbit of the Sun, although it is not very significant. This does depend slightly on whether one includes a bar, or not, as a bar has a clear effect on the dynamical features seen in the Solar neighbourhood (Paper III). This method can be used to find the possible properties of a bar. Finally, we look at the effect of a bar on a statistical system in the Milky Way, seeing that there are not only interesting effects depending on the mass and size of the bar, but also how bars can capture disc stars (Paper II).

International Advanced Water Technologies Centre, IAWTC/LADEC and LUT 2013 : Questionnaire Responses from Russian Drinking Water and Wastewater Treatment Plants

In this report, information is published concerning Russian water and wastewater treatment plants. The information is based on a questionnaire sent to 70 water and wastewater treatment plants in 2012-2013. The questionnaire was prepared by the International Advanced Water Technologies Centre (IAWTC) and Lahti Development Company (LADEC). The questions dealt with an assessment of the present state, the need for changes, renovation, investments, and how to improve the efficiency of the operation by training and investments. A significant need to renew the old pipelines, constructions, and processes was clearly evident. The aggregated answers can be utilized in Russia as internal benchmarking in order to arrange training and plant visits, which were requested in many of the answers. Sharing this open report with the respondents can aid networking and awareness of HELCOM requirements which relate to waste water treatment plants discharging their waste water directly or indirectly into the Baltic Sea. The aim of this report is to provide information for Finnish small and medium size companies (SMEs) as regards possible water related exportation to different parts of Russia.

Axotomy increases NADPH-diaphorase activity in the dorsal root ganglia and lumbar spinal cord of the turtle Trachemys dorbigni

Seven days after transection of the sciatic nerve NADPH-diaphorase activity increased in the small and medium neurons of the dorsal root ganglia of the turtle. However, this increase was observed only in medium neurons for up to 90 days. At this time a bilateral increase of NADPH-diaphorase staining was observed in all areas and neuronal types of the dorsal horn, and in positive motoneurons in the lumbar spinal cord, ipsilateral to the lesion. A similar increase was also demonstrable in spinal glial and endothelial cells. These findings are discussed in relation to the role of nitric oxide in hyperalgesia and neuronal regeneration or degeneration.

Aberrant crypt foci and colon cancer: comparison between a short- and medium-term bioassay for colon carcinogenesis using dimethylhydrazine in Wistar rats

Aberrant crypt foci (ACF) in the colon of carcinogen-treated rodents are considered to be the earliest hallmark of colon carcinogenesis. In the present study the relationship between a short-term (4 weeks) and medium-term (30 weeks) assay was assessed in a model of colon carcinogenesis induced by dimethylhydrazine (DMH) in the rat. Six-week-old male Wistar rats were given subcutaneous injections of DMH (40 mg/kg) twice a week for 2 weeks and killed at the end of the 4th or 30th week. ACF were scored for number, distribution pattern along the colon and crypt multiplicity in 0.1% methylene-blue whole-mount preparations. ACF were distinguished from normal crypts by their larger size and elliptical shape. The incidence, distribution and morphology of colon tumors were recorded. The majority of ACF were present in the middle and distal colon of DMH-treated rats and their number increased with time. By the 4th week, 91.5% ACF were composed of one or two crypts and 8.5% had three or more crypts, while by the 30th week 46.9% ACF had three or more crypts. Thus, a progression of ACF consisting of multiple crypts was observed from the 4th to the 30th week. Nine well-differentiated adenocarcinomas were found in 10 rats by the 30th week. Seven tumors were located in the distal colon and two in the middle colon. No tumor was found in the proximal colon. The present data indicate that induction of ACF by DMH in the short-term (4 weeks) assay was correlated with development of well-differentiated adenocarcinomas in the medium-term (30 weeks) assay.

Suorituskyvyn mittaaminen lasi- ja alumiinirakentamisen pk-yrityksissä

Diplomityön taustana oli oletus suorituskyvyn mittaamisen vähäisyydestä lasi- ja alumiinirakentamisen pk-yrityksissä. Tämän takia haluttiin tutkia mitataanko suorituskykyä ja jos mitataan, miten sitä tehdään sekä minkälainen järjestelmä sopisi kyseisille yrityksille. Lasi- ja alumiinirakentamisen suorituskyvyn analysoinnin tilannetta kartoitettiin haastattelututkimuksella, jossa kävi ilmi, että se tosiaan on vähäistä. Tutkimukseen osallistuneissa yrityksissä seurattiin pääasiassa liiketaloutta ja tulosta, ja näitäkin suppeasti. Laajemmalle mittaamiselle todettiin kuitenkin olevan tarvetta. Tämän jälkeen haastattelututkimuksen pohjalta suunniteltiin työssä mukana olleelle Case-yritykselle mittaristo. Suunnitteluvaiheessa valittiin yrityksen visioiden ja strategian mukaisesti neljä mitattavaa suorituskyvyn osa-aluetta ja näille mittarit. Mittariston suunnittelun jälkeen siirryttiin rakennusvaiheeseen. Järjestelmäksi valittiin SAKE, joka on helppokäyttöinen ja erityisesti pk-yritysten tarpeisiin suunniteltu työkalu. Tämän suorituskyvyn mittariston avulla lasi- ja alumiinirakentamisen yritykset voivat tehostaa toimintaansa ja ulottaa suorituskyvyn mittauksen osa-alueilla joita ei aiemmin ole huomioitu.

Physicochemical and sensory changes in aged sugarcane spirit submitted to filtering with activated carbon filter

Sugarcane spirit is a drink considered as a national symbol of Brazil. It is produced by large producers and by about 30 thousand small and medium home-distilling producers dispersed throughout the country. The copper originating from the home-distillers can become a serious problem since at high concentrations in beverages it may cause serious human health problems. Therefore, the objective of this study was to investigate the influence of the activated carbon used in commercial filters on the physicochemical and sensory characteristics of aged sugarcane spirit. Analyses of copper, dry extract, alcoholic degree, higher alcohols, volatile acids, aldehydes, esters, furfural, and methanol were performed. The sensory evaluation was performed by seven selected trained judges, who analyzed the yellow color, woody aroma and flavor, and intensity of alcoholic aroma and flavor of the cane spirit before and after the filtration process. The sensory tests were carried out using a 9 cm non-structured intensity scale. A reduction was observed in all compounds analyzed physicochemically, except for the esters, which increased after filtration. This increase is probably due to the esterification of the alcohols and acids present. According to the sensory results obtained, a reduction was observed in the intensity of the yellow color, aroma, and wood flavor characteristics, the major characteristics of the aging process.

Measurement of social value creation with non-financial measures

This research examines the concept of social entrepreneurship which is a fairly new business model. In the field of business it has become increasingly popular in recent years. The growing awareness of the environment and concrete examples of impact created by social entrepreneurship have encouraged entrepreneurs to address social problems. Society’s failures are tried to redress as a result of business activities. The purpose of doing business is necessarily no longer generating just profits but business is run in order to make a social change with the profit gained from the operations. Successful social entrepreneurship requires a specific nature, constant creativity and strong desire to make a social change. It requires constant balancing between two major objectives: both financial and non-financial issues need to be considered, but not at the expense of another. While aiming at the social purpose, the business needs to be run in highly competitive markets. Therefore, both factors need equally be integrated into an organization as they are complementary, not exclusionary. Business does not exist without society and society cannot go forward without business. Social entrepreneurship, its value creation, measurement tools and reporting practices are under discussion in this research. An extensive theoretical basis is covered and used to support the findings coming out of the researched case enterprises. The most attention is focused on the concept of Social Return on Investment. The case enterprises are analyzed through the SROI process. Social enterprises are mostly small or medium sized. Naturally this sets some limitations in implementing measurement tools. The question of resources requires the most attention and therefore sets the biggest constraints. However, the size of the company does not determine all – the nature of business and the type of social purpose need to be considered always. The mission may be so concrete and transparent that in all cases any kind of measurement would be useless. Implementing measurement tools may be of great benefit – or a huge financial burden. Thus, the very first thing to carefully consider is the possible need of measuring value creation.

Key factors in U.S. Government support of business internationalization in Finland Case: U.S. Embassy in Helsinki

This study discusses the importance of government intervention for companies and the expansion of national innovation systems. The purpose of the study is to examine the impact which the U.S. Embassy in Helsinki can have on Finnish businesses through their business support programs and events. The embassy has shifted focus in recent years with the creation of an innovation center and increased business services. The study has sub-objectives to discover the critical factors for producing impact, host and home based factor interaction, and effects produced by these initiatives. The theoretical background of the study consists of literature relating to the concepts of national innovation systems and government intervention. The empirical research conduct for this study is based on interviews with experts from the environment surrounding the U.S. Embassy in Helsinki, Finland and participation in embassy events. The data was collected between March 2014 and September 2015. Seven interviews were conducted; five with representatives of the U.S. Embassy and two with related organizations. Thematic analysis was used to categorize and interpret interview and observation data. The use of an impact radar was implemented as a basis for analysis. This study finds that the internationalization of national innovation systems provides interesting opportunities and challenges for national governments. The opportunity to provide services to foreign companies by an embassy in a stable environment opens the possibility to create positive notice and relations with the host country. The increased connections and inputs to the national innovation system of the home country have the potential to increase knowledge absorption and create positive growth. The most effective way for governments to encourage businesses is to create incentives and reduce barriers. The services are best aimed at small to medium sized companies in the early stages of development. The findings of this report suggest that the most critical factors for producing impact on companies are the ability to disseminate information effectively, the ability to create a positive image of the country, the ability to foster effective networks between the two countries, and the ability to facilitate the internationalization of companies. In the best cases, the embassy is able to create incentives to internationalize to the United States and reduce barriers which are encountered by companies. Future research is necessary to fully understand the impact of business services provided by an embassy can have on the political and economic relations of countries, and on particular industry sectors. The institutional setting provided by the embassy’s focus on business relations provides a rich environment for further study in a number of areas.

Barriers to Service-sector SME Internationalization in the EU Business Environment

The service sector in the global world is constantly growing: in Europe, they account currently approximately for 70 per cent of the total economy. Yet service internationalization is rather a new phenomenon: services have been traditionally seen as local entities, which also explains why research on service internationalization has properly begun only few decades ago. Even though the Single European Market allows free service movement between Member States, services do not move as actively as desired: approximately only one fifth of services are involved in cross-border trade. Therefore, the main purpose of this thesis is to analyze the barriers to service-sector SME internationalization in the EU business environment. To address the research purpose, the internationalization of service-sector SMEs in the EU area is first described and thereafter, the barriers to service-sector SME internationalization in the European context are mapped and analyzed from intra- and extra-firm perspectives. In order to understand the topic area and the phenomenon, a short glance is first taken into Europe as a business environment for service industries: the market characteristics and benefits of the common free trade area for service industries are described. Also earlier literature on service internationalization and barriers to international service trade are discussed. Due to low previous research activity on barriers specifically to international service trade, the discussion is improved by presenting general findings of barriers to SME internationalization. This research is conducted with qualitative methods: there is only a limited amount of previous research and qualitative methods provide a way of gathering in-depth information and reaching understanding from respondents’ perspectives. The evidence presented in the study was collected through six semi-structured interviews with six different small or medium sized international service firm representatives that all had the first-hand knowledge regarding their company’s process of delivering services from home market to other European countries. The results of the study provide a detailed description and analysis of intra- and extra-firm barriers to service-sector SME internationalization in the context of EU and indicate that in general, internal firm-specific barriers have a greater impact in determining firm’s possibilities to be engaged in cross-border service trade – external barriers played a smaller role. What might explain these results is that first of all, the study has full focus on service firms of smaller size and internal barriers tend to be particularly effective to SMEs as their resources, skills and capabilities are often limited, which limits internationalization possibilities. Second, the results may indicate that EU’s internal market and the free trade concept function quite well from service firms’ perspective, and the low service movement rate may be rather caused by firm’s own competences and resource-related difficulties than directly by flaws in the market. The results complete earlier literature and provide new and more detailed knowledge of barriers to cross-border service trade in the context of Europe. They also indicate that service internationalization should be observed separately from internationalization of traditional manufacturing firms due to unique service-specific characteristics. The findings of this study are particularly beneficial for small or medium sized service firm managers as it provides knowledge of delivering services across borders in Europe and of barriers that relate to that process.
