The effectiveness of vocationally oriented multidisciplinary rehabilitation (ASLAK®) amongst public sector employees

In Finland, vocationally oriented medical rehabilitation (ASLAK®) is a common preventive rehabilitation measure with the primary goal of preserving and improving work ability. The ASLAK® programme has been used for almost 30 years, although limited data exist on its effectiveness. The aims of this study were to determine whether the increased risk of work disability predicts the participants’ likelihood to be granted ASLAK® rehabilitation and to assess the effectiveness of the programme in decreasing the risk of work disability and modifying health-risk behaviours. This study is a part of the on-going Finnish Public Sector Study conducted by the Finnish Institute of Occupational Health. Data on 53 416 employees (81% women) were gathered from employers’ records, national health registers and repeated survey responses. During the 5-year follow-up, increased levels of the risk factors for work disability did not predict participation in the rehabilitation programme. During the 2.8-year followup (range 0.04–5.0 years), the risk of long-term work disability (sick leave >90 days or retirement) overall or, more specifically, due to musculoskeletal or mental diseases did not differ between the rehabilitants who participated in ASLAK® in 1997–2005 and their propensity score matched controls. There was no evidence of ASLAK® being effective in changing participants’ health-risk behaviours or in improving perceived general or mental health. The results suggest that potential participant recognition, mainly taking place in occupational health care, may fail to identify those with a higher risk of work disability. No evidence on the effectiveness of the programme was found in the study cohort when measured by the selected indicators.

Finnish Institutional Innovation Support Policies from Russian Entrepreneurs' Perspective: Establishing Cross-Border Technology Oriented Start-Up Firm

The purpose of this thesis is to study how Russian entrepreneurs perceive Finnish institutional environment and innovation support policies provided in the country, as well as to present a practical example in form of a case study of one technology oriented start-up firm which was established in Finland by Russian entrepreneurs. The empirical research of the thesis is conducted qualitatively in two parts. First part is conducted through online questionnaire with open questions in order to review the perceptions of Russian entrepreneurs in general. Second part is based on personal interviews with case company’s founders with the focus on the process of establishing the company in Finland. In the first part of the empirical research, five Russian start-up firms were contacted, and four responses were received. All of these responses were qualified for further analysis. The findings of the first part of the research reveal that Russian entrepreneurs have rather positive attitudes towards Finnish institutional innovation support policies. However, most of the entrepreneurs stated that they are unlikely to create their presence in Finland. As an outcome of the second part of the research, the process of establishing a case company in Finland is illustrated. In order to be able to establish companies in Finland, Russian entrepreneurs who have a permanent residence outside European Economic Area (EEA) are required to apply for a permission to perform business operations in the country. In addition, the established company must engage in improving the economical stand of the country by creating new work places, raising tax revenues, develop technologies and generate innovations in the country.

A new approach to evaluate imperfection sensitivity in asymmetric bifurcation buckling analysis

A direct procedure for the evaluation of imperfection sensitivity in bifurcation problems is presented. The problems arise in the context of the general theory of elastic stability for discrete structural systems, in which the energy criterion of stability of structures and the total potential energy formulation are employed. In cases of bifurcation buckling the sensitivity of the critical load with respect to an imperfection parameter e is singular at the state given by epsilon =0, so that, a regular perturbation expansion of the solution is not possible. In this work we describe a direct procedure to obtain the relations between the critical loads, the generalized coordinates at the critical state, the eigenvector, and the amplitude of the imperfection, using singular perturbation analysis. The expansions are assumed in terms of arbitrary powers of the imperfection parameter, so that both exponents and coefficients of the expansion are unknown. The solution of the series exponents is obtained by searching the least degenerate solution. The formulation is here applied to asymmetric bifurcations, for which explicit expressions of the coefficients are obtained. The use of the method is illustrated by a simple example, which allows consideration of the main features of the formulation.

Analysis of Regular and Irregular Dynamics of a Non Ideal Gear Rattling Problem

This paper presents a study on the dynamics of the rattling problem in gearboxes under non-ideal excitation. The subject has being analyzed by a number of authors such as Karagiannis and Pfeiffer (1991), for the ideal excitation case. An interesting model of the same problem by Moon (1992) has been recently used by Souza and Caldas (1999) to detect chaotic behavior. We consider two spur gears with different diameters and gaps between the teeth. Suppose the motion of one gear to be given while the motion of the other is governed by its dynamics. In the ideal case, the driving wheel is supposed to undergo a sinusoidal motion with given constant amplitude and frequency. In this paper, we consider the motion to be a function of the system response and a limited energy source is adopted. Thus an extra degree of freedom is introduced in the problem. The equations of motion are obtained via a Lagrangian approach with some assumed characteristic torque curves. Next, extensive numerical integration is used to detect some interesting geometrical aspects of regular and irregular motions of the system response.

Kuka luottaa ja mihin strategisessa kumppanuudessa? Case pankki ja kiinteistönvälitys

Tässä tutkielmassa tarkastellaan luottamuksen roolia kahden yrityksen välisessä yhteistyössä sekä sitä miten luottamus yhteistyössä rakentuu. Tavoitteena on selvittää mihin luottamus yhteistyössä kohdistuu ja mikä on henkilöityvän ja ei-henkilöityvän luottamuksen rooli. Tutkimuksen käytännöllinen tavoite on löytää keinoja, joilla yritysten johto voisi edesauttaa luottamuksen rakentumista. Lisäksi tarkastellaan sitä näyttääkö luottamuksella olevan vaikutusta yhteistyön toimivuuteen ja tuloksellisuuteen. Tämä laadullisen tutkimuksen teoreettinen osuus toteutettiin kirjallisuus-katsauksena. Empiirinen aineisto koostui haastatteluista, jotka toteutettiin molemmissa kohdeyrityksissä ja analysoitiin. Tutkimuksen tuloksena voidaan todeta, että luottamus on toimivan ja tu-loksellisen yhteistyön perusedellytys. Luottamus ilmenee sekä henkilöiden välisenä luottamuksena että ei-henkilöityvänä luottamuksena, jolloin se kohdistuu yritykseen, jonka kanssa yhteistyötä tehdään. Luottamus kohdistuu sekä toisen osapuolen kyvykkyyteen että hyväntahtoisuuteen. Tulosten perusteella ei pysty sanomaan onko henkilöityvällä luottamuksella tai ei-henkilöityvällä luottamuksella suurempi vaikutus yhteistyön toimivuuteen ja tuloksellisuuteen. Henkilöityvä luottamus ja ei-henkilöityvä luottamus eivät kuitenkaan kompensoi toisiaan. Tulosten perusteella näyttää siltä, että yhteistyö on tuloksellisinta kun osapuolet luottavat paitsi henkilöihin, joiden kanssa he yhteistyötä tekevät, myös kumppaniyrityksen brändiin, strategiaan sekä kaupalliseen kilpailukykyyn. Luottamusta rakentaa haastateltujen mukaan henkilösuhteiden lisäksi avoin ja selkeä tiedottaminen, ammattitaito, vuorovaikutus ja säännöllinen yhteydenpito, hyvät kokemukset ja saatu palaute, positiivinen asenne ja sitoutuminen, ongelmanratkaisukyky ja lupausten pitäminen. Yritysten johto voi rakentaa luottamusta mahdollistamalla ja vahvistamalla edellä mainittuja tekijöitä ja prosesseja.

Service paradox in a product oriented company: A service business development case

The master´s thesis had three aims; to develop a service portfolio, to support the management of services through the developed portfolio, and evaluate effects of service differentiation strategy on the future selection of services. The product oriented case company in service paradox is Hilti (Suomi) Oy, which is entering systematic service management era, supported by the late strategic change. Low return on service business investments is referred as service paradox. The project was carried out as a case study, where the primary information source was twenty-one conducted interviews. The theory part focuses on marketing logics, service strategies, and categorization of services. The empirical part contributes in solving the aim related research questions. As a result of the case study a service portfolio was created, next further steps in service management were suggested, and the effect on selection of services by service differentiation strategy was evaluated. The main goal of creating service portfolio contributes to systematic management of services, which required revising at the case company.

The duality of tactical thought : a study of how Swedish land forces' commanders view tactics in irregular warfare

This is a sociological study of the views of officers in the Swedish Army and its Amphibious Forces on tactics in Irregular Warfare (IW), in particular, Counterinsurgency (COIN). IW comprises struggles, where the military weaker part uses an indirect approach with smaller units and integrates the civilian and military dimensions in a violence spectrum including subversion, terrorism, Guerrilla Warfare and infantry actions. IW is the main armed warfare style in insurgencies. COIN is the combined political, military, economic, social and legal actions in counter insurgencies. Data has been collected by means of interviews with almost all (n =43) officers, who were either commanding battalions or rifle and manoeuvre companies while undergoing training for general warfare and international operations. The main theoretical and methodological inspiration is the traditional one for research on social fields, inaugurated by the French sociologist Pierre Bourdieu. The statistical technique used is Multiple Correspondence Analysis. As a background and context base, an inquiry inspired by the Begriffsgechichte (Conceptual History) tradition explores the genesis and development of understandings of the term Irregular Warfare. The research question is outlined as; “how can contemporary Swedish military thought on tactics in Irregular Warfare be characterized using descriptive patterns, mapped in relation to background factors and normative standards? The most significant findings are that there are two main opposing notions separating the officers’ views on tactics in Irregular Warfare: (1) a focus on larger, combat oriented and collectively operating military units versus smaller and larger, more intelligence oriented and dispersed operating units, and (2) a focus on military tasks and kinetic effects versus military and civilian tasks as well as “soft” effects. The distribution of these views can be presented as a two-dimensional space structured by the two axes. This space represents four categories of tactics, partly diverging from normative military standards for Counterinsurgency. This social space of standpoints shows different structural tendencies for background factors of social and cultural character, particularly dominant concerning military backgrounds, international mission experiences and civilian education. Compared to military standards for Counterinsurgency, the two tactical types characterized by a Regular Warfare mind-set stands out as counter-normative. Signs of creative thought on military practice and theory, as well as a still persistent Regular Warfare doxa are apparent. Power struggles might thus develop, effecting the transformation to a broadened warfare culture with an enhanced focus also on Irregular Warfare. The result does not support research results arguing for a convergence of military thought in the European transformation of Armed Forces. The main argument goes beyond tactics and suggests sociological analysis on reciprocal effects regarding strategy, operational art, tactics as well as leadership, concerning the mind-set and preferences for Regular, Irregular and Hybrid Warfare.
