Incumbent audit firm-provided tax services and the clients with low financial reporting quality

This study investigates whether incumbent audit firm-provided tax services enhance or impair the likelihood of acknowledging client companies’ low financial reporting quality. In particular, we examine the association between tax-related fees and the likelihood of timely restatements, and internal control weakness disclosures among a sample of US companies that all have misstatements in financial information. The empirical findings indicate that companies paying higher tax-related fees are less likely to disclose SOX 404 internal control weakness disclosures, implying that underlying control problems are unacknowledged when incumbent audit firm provided tax-related fees are higher. However, the findings suggest that just providing both audit and tax-related services does not have an impact on audit quality per se, but rather it is the magnitude of the tax-related fees in particular that counts. We also find some evidence suggesting that companies paying higher tax-related fees have higher likelihood of restatement lags, whereas companies paying smaller tax-related fees to their audit firm restate financial statements in a timelier manner. Overall, the findings suggest that audit scrutiny of client companies with low quality financial reporting is weaker when the magnitude of tax-related fees is higher.

Warranty Practices and Costs in the Industry of Welding Machines Manufacturing

The objective of the master’s thesis is to define the warranty practices and costs in the welding machines manufacturing company and do a proposal for a warranty policy based on the practices and costs. The study include a disquisition of the warranty practices in the subsidiaries and distributor sales. The disquisition of the warranty practices introduces the information relates to warranty period, warranty costs, including repair, spare part and other costs, the practices with the replaced parts, the utilization rate of the eWarranty system and information relates to special arrangements in the warranties. The warranty costs are defined besides the group level also separately per regions and product families. From some product families the disquisition is done per products. In this study is also done a proposal for a warranty policy for the company. The proposal speaks out the length of warranty period, the compensation of the warranty costs, the practices with replaced parts and usage of eWarranty system.

Studies of Eu- and Yb-induced Reconstructions on the Si(100) Surface

This thesis presents experimental studies of rare earth (RE) metal induced structures on Si(100) surfaces. Two divalent RE metal adsorbates, Eu and Yb, are investigated on nominally flat Si(100) and on vicinal, stepped Si(100) substrates. Several experimental methods have been applied, including scanning tunneling microscopy/spectroscopy (STM/STS), low energy electron diffraction (LEED), synchrotron radiation photoelectron spectroscopy (SR-PES), Auger electron spectroscopy (AES), thermal desorption spectroscopy (TDS), and work function change measurements (Δφ). Two stages can be distinguished in the initial growth of the RE/Si interface: the formation of a two-dimensional (2D) adsorbed layer at submonolayer coverage and the growth of a three-dimensional (3D) silicide phase at higher coverage. The 2D phase is studied for both adsorbates in order to discover whether they produce common reconstructions or reconstructions common to the other RE metals. For studies of the 3D phase Yb is chosen due to its ability to crystallize in a hexagonal AlB2 type lattice, which is the structure of RE silicide nanowires, therefore allowing for the possibility of the growth of one-dimensional (1D) wires. It is found that despite their similar electronic configuration, Eu and Yb do not form similar 2D reconstructions on Si(100). Instead, a wealth of 2D structures is observed and atomic models are proposed for the 2×3-type reconstructions. In addition, adsorbate induced modifications on surface morphology and orientational symmetry are observed. The formation of the Yb silicide phase follows the Stranski-Krastanov growth mode. Nanowires with the hexagonal lattice are observed on the flat Si(100) substrate, and moreover, an unexpectedly large variety of growth directions are revealed. On the vicinal substrate the growth of the silicide phase as 3D islands and wires depends drastically on the growth conditions. The conditions under which wires with high aspect ratio and single orientation parallel to the step edges can be formed are demonstrated.

Kiinteistönvälittäjän vastuu vanhan asunnon kaupassa

Tutkielman tarkoituksena oli selvittää kiinteistönvälittäjän vastuuta vanhan asunnon kaupassa, kun toisena osapuolena on kuluttajan asemassa oleva yksityishenkilö. Työn perustana on kiinteistönvälittäjän toimintaa ohjaava voimassa oleva lainsäädäntö. Tutkimusaineistona käytettiin lisäksi kirjallisuutta ja viime vuosien oikeuskäytäntöä. Kiinteistönvälittäjän vastuu kaupan osapuolille perustuu joko sopimus- tai vahingonkorvausvastuuseen riippuen siitä, onko vahinkoa kärsinyt toimeksiantaja vai tämän vastapuoli. Vastuu edellyttää virhettä välittäjän toiminnassa, joka on tuottamuksen lisäksi syy-yhteydessä aiheutuneeseen vahinkoon. Välittäjän toimissa on virhe, jos se ei vastaa sovittua tai laissa säädettyä.

Magneto-V1: um programa para o cálculo de correções diamagnéticas e de momentos magnéticos efetivos

A new computer program has been developed to help the users of force methods for magnetic moment determination. It provides a user-friendly interface for the calculation of corrected magnetic susceptibilities of paramagnetic materials and enables the user to simulate a number of chemical formulations for the sample under study. The program is written in the Perl scripting language and runs on a Unix platform.
