This study provides following theoretical and managerial contributions. Firstly, it proposes a methodology for comparative analysis of energy performance of Russian and foreign gold mining companies. Secondly, this study provides comprehensive analysis of main energy efficiency challenges relevant for a Russian gold mining company. Finally, in order to overcome identified challenges this research conceives a guidance for a gold mining company for implementation of energy management system based on the ISO standard.

Ulkoistuksesta luopumisen kannattavuusarviointi panimoalan yrityksessä

Ulkoistaminen on ollut pitkään yhtenä strategisen päätöksenteon osa-alueena, mutta ulkoistuksesta luopuminen on ollut vähemmän esillä. Tämä työ käsittelee lahtelaisen Teerenpeli Panimo & Tislaamo Oy:n yhden logistiikan osa-alueen ulkoistamisen ja ulkoistuksesta luopumisen välistä kannattavuutta. Tällä hetkellä ulkopuolinen yritys vastaa ravintola-astioiden pesu- ja varastointijärjestelyistä. Nyt laajentuneen toiminnan ja kasvaneen kysynnän ansiosta selvitetään ulkoistuksesta luopumisen mahdollisuutta yhtenä tulevaisuuden vaihtoehtona. Vaihtoehtoisia toimintamalleja on kaksi. Ensimmäisessä yritys investoisi omaan pesu- ja täyttöjärjestelmään ja vastaisi myös ravintola-astioiden logistiikasta kokonaisuudessaan. Näin ollen ulkopuolisen toimijan hyödyntäminen ravintolaastioiden logistiikassa jäisi pois. Toinen vaihtoehtoinen malli liittyy äskettäin markkinoilla suosiota saaneisiin niin sanottujen yksisuuntaisten ravintola-astioiden käyttöönottoon. Näitä astioita ei uudelleen pestä lainkaan, vaan käytön jälkeen hävitetään edelleen kierrätettäväksi. Diplomityön lopussa arvioidaan eri mallien välistä kannattavuutta taloudellisin perustein. Tämän lisäksi mallien välistä kannattavuutta arvioidaan taloudellisten mittareiden ulkopuolisilla tekijöillä, esimerkiksi ulkoistuksesta luopumisen vaikutuksia muuhun jäljelle jäävään yhteistyön. Lopussa annetaan myös toimintaohjeet tulevaa varten.

The roles and tasks of salespeople in Software-as-a-Service company's value-based sales process

Recent research in relationships marketing and sales and sales management emphasizes companies’ ability to create customer value as a core of all business-to-business relationships. The role of individual salespeople in business relation-ships is commonly acknowledged, but has been largely neglected in extant literature. This study offers especially more detailed perspective on salespeople’s roles and tasks in business-to-business value-based sales process. It focuses especially on Software-as-a-Service business environment. The objective of the study is to find out how salespeople can create value in Software-as-a-Service value-based sales process. It determines value-based sales process, salespeople’s roles and tasks in it, and combines value assessment in to process. The results indicate that salespeople have to adapt different selling roles and tasks in Software-as-a-Service value-based sales process to be able to support the customer’s value-in-use experience. The process itself is highly complex, consisting of multiple facets and selling behaviors, and involves relevant actors from both parties of relationship. The study concludes with a discussion of possibilities that provide interesting aspects for future research.

Data and Inventory Management in Spare Part Business: Developing Operations in the Case Company

After sales business is an effective way to create profit and increase customer satisfaction in manufacturing companies. Despite this, some special business characteristics that are linked to these functions, make it exceptionally challenging in its own way. This Master’s Thesis examines the current situation of the data and inventory management in the case company regarding possibilities and challenges related to the consolidation of current business operations. The research examines process steps, procedures, data requirements, data mining practices and data storage management of spare part sales process, whereas the part focusing on inventory management is reviewing the current stock value and examining current practices and operational principles. There are two global after sales units which supply spare parts and issues reviewed in this study are examined from both units’ perspective. The analysis is focused on the operations of that unit where functions would be centralized by default, if change decisions are carried out. It was discovered that both data and inventory management include clear shortcomings, which result from lack of internal instructions and established processes as well as lack of cooperation with other stakeholders related to product’s lifecycle. The main product of data management was a guideline for consolidating the functions, tailored for the company’s needs. Additionally, potentially scrapped spare part were listed and a proposal of inventory management instructions was drafted. If the suggested spare part materials will be scrapped, stock value will decrease 46 percent. A guideline which was reviewed and commented in this thesis was chosen as the basis of the inventory management instructions.

Carbon pricing and its effect on company profitability

In order to reach the 2°C climate target, the carbon price should rise significantly in order for it to be financially rewarding for companies to reduce their emissions. This research aims to find how a significant increase in the carbon price would affect the profitability of companies. Prior research has not found consensus on how regulatory policies affect companies. This research looks at profitability factors of carbon pricing through a mix of related issues such as the carbon risk, carbon pricing mechanisms and cost pass-through of additional costs. The research is quantitative and examines financial data and emissions data regarding scope 1 and scope 2 emissions on 328 European companies. The data analysis method utilised is a sensitivity analysis conducted as a scenario analysis. Different price increases and cost pass-through rates are tested to see how company profitability is affected. As the companies are distributed between 9 sectors and 53 industries, the results vary. The industries that are found to be affected by an increase in carbon pricing show drastic negative changes in profitability. The results complement prior research identifying the most carbon-intensive industries, but also provide some new insights on industries that may be affected by carbon pricing. Industries related to manufacturing, electricity and energy are partly significantly impacted, but also industries related to tourism and food show potential signs of impact when an increased carbon price is introduced.

How to reach more potential global b2b customers to Finnish high tech company websites

This thesis examines the optimization of a website in terms of creating website visibility and interesting and attractive online information, with the aim of finding ways how the case company can increase the number of online visitors for the websites, who would even-tually contact the case company, and become customers. The theoretical part concentrates on website visibility, academic knowledge about search engine optimization, integrated marketing communications, website effectiveness and influence tactics (mostly non-coercive) in an online b2b buying context. The empirical part included an experiment of two weeks on the case website. Search engine optimization requires the most relevant key terms and keywords to be selected and carefully implemented to meta descriptions of the most informational pages. The information visible to visitors on these pages was also opti-mized to make it interesting and purposeful for the targeted audience. The most suitable influence tactics were implemented to certain pages to attract the website visitors to con-tact the case company. The results suggest that relevant key terms in meta descriptions do improve, or maintain the same high, ranking a page has on search engine result pages, but this is not directly connected to the amount of visitors to the website. The number of visi-tors does not either affect the amount of customer contacts the company received during the experiment period.

A Drop of Success – Internationalization Readiness of a Young Finnish Company

This study analyzes a young Finnish micro-sized firm that is attempting to reach internationalization readiness in the pre-internationalization stage. The purpose of this research is to analyze and better understand how a young firm reaches internationalization readiness in the pre-internationalization stage. Small firm internationalization is a vastly researched topic. Little emphasis has been placed on the specific antecedents that help the firm reach internationalization readiness in the pre-internationalization stage. The contribution of this research is thus two-fold. First, the research contributes to known theories of firm internationalization. Second, the research further extends knowledge related to how firms reach internationalization readiness specifically in the pre-internationalization stage. The theoretical background of the research involves the traditional stage theory (Uppsala model), pre-internationalization stage theory, international entrepreneurship theory and dynamic capabilities theory. With the help of these four relevant theories, empirical data was collected. The research method utilized in this study was a qualitative single case study combined with critical realist philosophy. The data analysis of this research was conducted using abduction in order to allow freedom in the analysis of the research findings. The empirical data was collected through semi-structured, face-to-face interviews. The key respondents in this study were the two managers of the case company. The findings of this study revealed four important themes from the case company’s perspective towards reaching internationalization readiness in the pre-internationalization stage. Extensive knowledge of the home market and target market were the two most important themes in this research. The next most relevant theme for reaching internationalization readiness in the pre-internationalization stage was the managers’ previous international business experiences. The final theme affecting the firm’s ability to reach internationalization readiness was the firm’s specific resources. Even though the research findings of this study are case sensitive, the research insights and explanations have the potential to be transferred to similar firms and contexts. Future research should therefore aim towards more longitudinal studies in which the context is emphasized. This should include a variety of firms in similar stages of internationalization and contexts. Future studies of this kind would be of great benefit to academia.

Improving purchasing process for small purchases at a manufacturing company in chemical industry

This thesis was conducted on assignment by a multinational chemical corporation as a case study. The purpose of this study is to find ways to improve the purchasing process for small purchases at the case company. The improvements looked after are mainly cost and time savings. Purchasing process is the process that starts from the requisition of goods or services and ends when the invoice is paid. In this thesis the purchases with value less than 1000€ are considered to be small. The theoretical framework of the thesis consists of general theoretical view of costs and performance of the purchasing process, different types of purchasing processes and a model for improving purchasing processes. The categorization to small and large purchases is the most important followed by the division between direct and indirect purchases. Also models that provide more strategic perspective for categorization were found to be useful. Auditing and managerial control are important parts of the purchasing process. When considering the transaction costs of purchasing from the costs–benefits perspective large and small purchases should not have the same processes. Purchasing cards, e-procurement and vendor managed inventory are seen as an alternative to the traditional purchasing process. The empirical data collection was done by interviewing the company employees that take part of the purchasing process in their daily work. The interviews had open-ended questions and the answers were coded and analyzed. The results consist of process description and assessment as well as suggestions for potential improvements. At the case company the basic purchasing process was similar to the traditional purchasing process that is entirely done with computers and online. For some categories there was already more sophisticated e-procurement solutions in use. To improve the current e-procurement based solutions elimination of authorization workflow and better information exchange can be seen as potential improvements for most of the case purchases. Purchasing cards and a lightweight form of vendor managed inventory can be seen as potential improvements for some categories. Implementing the changes incurs at least some cost and the benefits might be hard to measure. This thesis has revealed that the small purchases have potential for significant cost and time savings at the case company.

Geochemistry and mineralogical association of heavy metal contaminants in fine grained sediment, Welland River, Southern Ontario /

This investigation of geochemistry and mineralogy of heavy metals in fine grained (<63^m) sediment of the Welland River was imdertaken to: 1) describe metal dispersion patterns relative to a source, identify minerals forming and existing at the outfall region and relate sediment particle size to chemistry; 2) to delineate sample handling, preparation and evaluate, modify and develop analytical methods for heavy metal analysis of complex environmental samples. Ajoint project between Brock University and Geoscience Laboratories was initiated to test a contaminated site of the Welland River at the base of Atlas Speciality Steels Co. Methods were developed and utilized for particle size separation and two acid extraction techniques: 1) Partial extraction; 2) Total extraction. The mineralogical assessment identified calcite, dolomite, quartz and clays. These minerals are typical of the carbonate-shale rock basement of the Niagara Peninsula. Minerals such as, mullite and ferrocolumbite were found at the outfall region. These are not typical of the local geology and are generally associated with industrial pollutants. Partial and total extraction techniques were used to characterize the sediments based on chemical distribution, elemental behaviour and analytical differences. The majority of elements were lower in concentration in the partial extraction technique; suggesting these elements are bound in an acid extractable phase (exchangeable, organic and carbonate phases). The total extraction technique yielded higher elemental concentrations taking difficult oxides and silicates into solution. Geochemical analyses of grain size separates revealed that heavy metal (Co, Ni, V, Mn, Fe, Ba) concentrations did not increase with decreasing grain size. This is a function of the anthropogenic mill scale input into the river. The background elements (Sc, Y, Sr, Mg, Al and Ti) showed an increase in concentration to the finest grain size suggesting that it is directly related to the local mineralogy and geology. Dispersion patterns ofmetals fall into two distinct categories: 1) the heavy metals (Co, Cu, Ni, Zn, V and Cr), and 2) the background elements (Be, Sc, Y, Sr, Al and Ti). The heavy metals show a marked increase in the outfall region, while the background elements show a significant decrease at the outfall. This pattern is attributed to a "dilution effect" ofthe natural sediments by the anthropogenic mill scale sediments. Multivariant statistical analysis and correlation coefficient matrix results clearly support these results and conclusions. These results indicate the outfall region ofthe Welland River is highly contaminated with to heavy metals from the industrialized area of Welland. A short distance downstream, the metal concentrations return to baseline geochemical levels. It appears, contaminants rapidly come out of suspension and are deposited in close proximity to the source. Therefore, it is likely that dredging the sediment from the river may cause resuspension of contaminated sediments, but may not distribute the sediment as far as initially anticipated.

Sample preparation and heavy metal determination by atomic spectrometry /

Microwave digestions of mercury in Standards Reference Material (SRM) coal samples with nitric acid and hydrogen peroxide in quartz vessels were compared with Teflon® vessel digestion by using flow injection cold vapor atomic absorption spectrometry. Teflon® vessels gave poor reproducibiUty and tended to deliver high values, while the digestion results from quartz vessel show good agreement with certificate values and better standard deviations. Trace level elements (Ag, Ba, Cd, Cr, Co, Cu, Fe, Mg, Mn, Mo, Pb, Sn, Ti, V and Zn) in used oil and residual oil samples were determined by inductively coupled plasma-optical emission spectrometry. Different microwave digestion programs were developed for each sample and most of the results are in good agreement with certified values. The disagreement with values for Ag was due to the precipitation of Ag in sample; while Sn, V and Zn values had good recoveries from the spike test, which suggests that these certified values might need to be reconsidered. Gold, silver, copper, cadmium, cobalt, nickel and zinc were determined by continuous hydride generation inductively coupled plasma-optical emission spectrometry. The performance of two sample introduction systems: MSIS™ and gas-liquid separator were compared. Under the respective optimum conditions, MSIS^"^ showed better sensitivity and lower detection limits for Ag, Cd, Cu, Co and similar values for Au, Ni and Zn to those for the gas-liquid separator.

A fast atom bombardment mass spectrometry study of tris (3, 6-dioxaheptyl) amine-alkali metal halide complexes and hydrogen bonded complexes

The objective of this thesis was to demonstrate the potential of fast atom bombardment mass spectrometry (FABMS) as a probe of condensed phase systems and its possible uses for the study of hydrogen bonding. FABMS was used to study three different systems. The first study was aimed at investigating the selectivity of the ligand tris(3,6-dioxaheptyl) amine (tdoha) for the alkali metal cations. FABMS results correlated well with infrared and nmr data. Systems where a crown ether competed with tdoha for a given alkali metal cation were also investigated by fast atom bombardment. The results were found to correlate with the cation affinity of tdoha and the ability of the crown ether to bind the cation. In the second and third studies, H-bonded systems were investigated. The imidazole-electron donor complexes were investigated and FABMS results showed the expected H-bond strength of the respective complexes. The effects of concentration, liquid matrix, water content, deuterium exchange, and pre-ionization of the complex were also investigated. In the third system investigated, the abundance of the diphenyl sulfone-ammonium salt complexes (presumably H-bonded) in the FABMS spectrum were found to correlate with qualitative considerations such as steric hindrance and strength of ion pairs.

Metal complexes involving pyridoxine and pyridoxamine

Solid complexes of pyridoxine with Mn(II) , Cd(II) and Zn(II) have been isolated, as well as compounds containing Cu(II), Ni(II), Co(III), Cd(II) and Zn(II), and pyridoxamine in various protonated forms. Infrared spectra provide evidence for protonation at the pyridine nitrogen site in the complexes, but not in the neutral vitamins and the complexes of anionic pyridoxamine. Thus the complexed vitamins are in zwitterionic forms, with chelation probably occurring through the phenolate oxygen and either the amino or the hydroxy group at the 4' position.

Molecular mechanics calculations on some phosphine oxide metal complexes in aqueous and organic solvents

Molecular mechanics calculations were done on tetrahedral phosphine oxide zinc complexes in simulated water, benzene and hexane phases using the DREIDING II force field in the BIOGRAF molecular modeling program. The SUN workstation computer (SUN_ 4c, with SPARK station 1 processor) was used for the calculations. Experimental structural information used in the parameterization was obtained from the September 1989 version of the Cambridge Structural Database. 2 Steric and solvation energies were calculated for complexes of the type ZnCl2 (RlO)2' The calculations were done with and without inclusion of electrostatic interactions. More reliable simulation results were obtained without inclusion of charges. In the simulated gas phase, the steric energies increase regularly with number of carbons in the alkyl group, whereas they go through a maximum when solvent shells are included in the calculation. Simulated distribution ratios vary with chain length and type of chain branching and the complexes are found to be more favourable for extraction by benzene than by hexane, in accord with experimental data. Also, in line with what would be expected for a favorable extraction, calculations without electrostatics predict that the complexes are better solvated by the organic solvents than by water.

Reactions of polyhalogenated aromatic compounds and related ethers with metal/ammonia solutions

This work contains the results of a series of reduction studies on polyhalogenated aromatic compounds and related ethers using alkali metals in liquid ammonia. In general, polychlorobenzenes were reduced to t he parent aromatic hydrocarbon or to 1 ,4-cyc1ohexadiene, and dipheny1ethers were cleaved to the aroma tic hydrocarbon and a phenol. Chlorinated dipheny1ethers were r eductive1y dechlorinated in the process. For example, 4-chlorodipheny1- ether gave benzene and phenol. Pentach1orobenzene and certain tetrachlorobenzenes disproportionated to a fair degree during the reduction process if no added proton source was present. The disproportionation was attributed to a build-up of amide ion. Addition of ethanol completely suppressed the formation of any disproportionation products. In the reductions of certain dipheny1ethers , the reduction of one or both of the dipheny1ether rings occurred, along with the normal cleavage. This was more prevalent when lithium was the metal used . As a Sidelight, certain chloropheno1s were readily dechlorinated. In light of these results, the reductive detoxification of the chlorinated dibenzo-1,4-dioxins seems possible with alkali metals in l iquid ammonia.
