Motivating techniques within Irish and American manufacturing and service companies in the Northwest of Ireland

In today’s world, many companies are concentrating on both their technology and human resources to provide them with their competitive advantage. Hence, understanding what motivates people is particularly important for managers in order to develop and sustain a competitive edge. As a result, numerous theories have been advanced to help our understanding of the subject matter and from these theories many motivational methods have evolved to enhance motivation within the workplace. In addition, research has been conducted on the various types of motivational techniques utilised by companies within Ireland. However, very little research has been completed within specific geographical regions in Ireland concerning the types of motivational techniques implemented at different job levels and their impact on employees work performance. Thus the objective of this research was to identify the motivational techniques utilised at different job levels within large manufacturing and service companies in the Northwest of Ireland and examine how these techniques influence the performance levels of employees. Furthermore, the study examined if these companies have changed from traditional ways of motivating employees to newer techniques. The research methodologies used to undertake the research included interviews with the HR managers and questionnaires completed by different employees at various job levels within the participating companies. Overall the conclusions were varied. Many different types of motivation techniques were found within the study’s participating companies. Irish companies are improving their motivational techniques, however most of these techniques are only used within higher job levels. In contrast to their American counterparts, a variety of motivational techniques are utilised and implemented at all job levels. On a more positive note, the majority of these motivational techniques do increase performance levels at all job levels. From the extensive primary and secondary research conducted, the thesis concludes by offering a number of recommendations to assist companies in further development of their motivational techniques for all job levels. These recommendations hope to augment the success of companies through an enhanced motivated workforce.

Improving the effort concept: a revision of the traditional approach in the context of controlled Dynamic Stochastic Environments

The objective of this paper is to re-evaluate the attitude to effort of a risk-averse decision-maker in an evolving environment. In the classic analysis, the space of efforts is generally discretized. More realistic, this new approach emploies a continuum of effort levels. The presence of multiple possible efforts and performance levels provides a better basis for explaining real economic phenomena. The traditional approach (see, Laffont, J. J. & Tirole, J., 1993, Salanie, B., 1997, Laffont, J.J. and Martimort, D, 2002, among others) does not take into account the potential effect of the system dynamics on the agent's behavior to effort over time. In the context of a Principal-agent relationship, not only the incentives of the Principal can determine the private agent to allocate a good effort, but also the evolution of the dynamic system. The incentives can be ineffective when the environment does not incite the agent to invest a good effort. This explains why, some effici

Is there a common factor for vision?

In cognition, common factors play a crucial role. For example, different types of intelligence are highly correlated, pointing to a common factor, which is often called g. One might expect that a similar common factor would also exist for vision. Surprisingly, no one in the field has addressed this issue. Here, we provide the first evidence that there is no common factor for vision. We tested 40 healthy students' performance in six basic visual paradigms: visual acuity, vernier discrimination, two visual backward masking paradigms, Gabor detection, and bisection discrimination. One might expect that performance levels on these tasks would be highly correlated because some individuals generally have better vision than others due to superior optics, better retinal or cortical processing, or enriched visual experience. However, only four out of 15 correlations were significant, two of which were nontrivial. These results cannot be explained by high intraobserver variability or ceiling effects because test-retest reliability was high and the variance in our student population is commensurate with that from other studies with well-sighted populations. Using a variety of tests (e.g., principal components analysis, Bayes theorem, test-retest reliability), we show the robustness of our null results. We suggest that neuroplasticity operates during everyday experience to generate marked individual differences. Our results apply only to the normally sighted population (i.e., restricted range sampling). For the entire population, including those with degenerate vision, we expect different results.

Organizational configurations of strategic choices and strategic management accounting

This is the first study to adopt a configurational paradigm in an investigation of strategic management accounting (SMA) adoption. The study examines the alignment and effectiveness of strategic choice and strategic management accounting (SMA) system design configurations. Six configurations were derived empirically by deploying a cluster analysis of data collected from a sample of 193 large Slovenian companies. The first four clusters appear to provide some support for the central configurational proposition that higher levels of vertical and horizontal configurational alignments are associated with higher levels of performance. Evidence that contradicts the theory is also apparent, however, as the remaining two clusters exhibit high degrees of SMA vertical and horizontal alignment, but low performance levels. A particular contribution of the paper concerns its demonstration of the way that the configurational paradigm can be operationalised to examine management accounting phenomena and the nature of management accounting insights that can derive from applying the approach.

IOWA Students with Autism: Who are they, how are they served, and are they achieving? October 2012

The Iowa Department of Education completed two studies in 2011-2012. The studies addressed several areas of need: (a) identifying students likely on the Autism Spectrum, (b) examining where large numbers of students on the Autism Spectrum are attending school, (c) evaluating the services being provided to students and the location of those services, (d) determining the extent to which services are evidence-based, (e) determining if services are sufficient to effect change needed to reach performance levels needed to access life opportunity, (f) understanding the kinds of problems being addressed through the Individualized Education Programs (IEPs) for the students identified, (g) examining the severity of behavior problems in the sample, and (h) examining academic proficiency and growth for students likely to be on the Autism Spectrum.

Review of Cold In-Place Recycled Asphalt Concrete Projects, HR-392, 1998

Highway Research Project HR-392 was undertaken to evaluate cold in-place asphalt recycled (CIR) projects in the State of Iowa. The research involved assessment of performance levels, investigation of factors that most influence pavement performance and economy, and development of guidelines for CIR project selection. The performance was evaluated in two ways: Pavement Condition Indices (PCI, U.S. Corps of Engineers) were calculated and overall ratings were given on ride and appearance. A regression analysis was extrapolated to predict the future service life of CIR roads. The results were that CIR roads within the State of Iowa, with less than 2000 annual average daily traffic (AADT), have an average predicted service life of fifteen to twenty-six years. Subgrade stability problems can prevent a CIR project from being successfully constructed. A series of Dynamic Cone Penetrometer (DCP) tests were conducted on a CIR project that experienced varying levels of subgrade failure during construction. Based on this case study, and supporting data, it was determined that the DCP test can be used to evaluate subgrades that have insufficient stability for recycling. Overall, CIR roads in Iowa are performing well. It appears that the development of transverse cracking has been retarded and little rutting has occurred. Contracting agencies must pay special attention to the subgrade conditions during project selection. Because of its performance, CIR is a recommended method to be considered for rehabilitating aged low volume (<2000 AADT) asphalt concrete roads in Iowa.

Resident health-related quality of life in Swiss nursing homes.

BACKGROUND: Health-related quality of life (HRQOL) levels and their determinants in those living in nursing homes are unclear. The aim of this study was to investigate different HRQOL domains as a function of the degree of cognitive impairment and to explore associations between them and possible determinants of HRQOL. METHOD: Five HRQOL domains using the Minimum Data Set - Health Status Index (MDS-HSI) were investigated in a large sample of nursing home residents depending on cognitive performance levels derived from the Cognitive Performance Scale. Large effect size associations between clinical variables and the different HRQOL domains were looked for. RESULTS: HRQOL domains are impaired to variable degrees but with similar profiles depending on the cognitive performance level. Basic activities of daily living are a major factor associated with some but not all HRQOL domains and vary little with the degree of cognitive impairment. LIMITATIONS: This study is limited by the general difficulties related to measuring HRQOL in patients with cognitive impairment and the reduced number of variables considered among those potentially influencing HRQOL. CONCLUSION: HRQOL dimensions are not all linearly associated with increasing cognitive impairment in NH patients. Longitudinal studies are required to determine how the different HRQOL domains evolve over time in NH residents.

Toiminnan laadun parantaminen organisaation itsearvioinnilla – tutkimus Suomen puolustusvoimien tulosyksiköissä

Laajoilla kyselylomaketutkimuksilla on tutkittu organisaation itsearvioinnin käyttöönoton motiiveja, käyttöä ja käytön hyötyjä 1990-luvulla ja 2000-luvun alussa. Organisaation itsearviointia on myös tutkittu laatupalkintomallien soveltamisen yhteydessä. Kolmas tutkimussuuntaus, johon myös tämä tutkimus sisältyy, on organisaation itsearvioinnin tutkiminen erilaisissa asiayhteyksissä. Tämän tutkimuksen tarkoituksena on lisätä tietoa ja ymmärrystä organisaation itsearvioinnista ja sen vaikuttavuudesta tutkimalla, miten organisaatiota itsearvioidaan maavoimien valmiusyhtymissä ja Maasotakoulussa. Näissä neljässä paikallistutkimuksessa käytin tutkimusotteena tapaustutkimuksen mukaista tutkimusstrategiaa. Aiempien tutkimuksien tulosten perusteella tärkein yhdistävä tekijä toiminnan parantamisessa on pyrkimys kokonaisvaltaisuuteen toiminnan laadun parantamisessa ja erinomaisuuden tavoittelussa. Osin kokonaisvaltaisuuteen sisältyviä ja sitä tukevia tekijöitä ovat jatkuvan parantamisen periaatteen käyttäminen ja oppivan organisaation edellyttämien toimintaedellytyksien luominen ja niiden huomioon ottaminen toiminnassa. Edelleen yhteisenä tekijänä ovat johdon sitoutumisen ja osallistumisen vaikutukset työntekijöiden osallistumiseen ja sitoutumiseen. Teorian perusteella olen arvioinut muodostuvan kolme organisaation itsearvioinnin strategisen tason johtamiskäytäntöä, jotka ovat ”Laatupalkinnon hakeminen”, ”Toiminnan ja tulosten arviointi” sekä ”Toiminnan kypsyyden arviointi”. Tutkimuksen tulosten perusteella organisaation itsearvioinnin vaikuttavuuden merkityskokonaisuus on selitettävissä viiden teeman avulla. Koko tutkimusaineiston yhdistäväksi vaikuttavuuden teemaksi, josta myös organisaation itsearvioinnin vaiheistus saa tukea, muodostuu teema ”organisaation itsearviointi ja tulosjohtaminen”. Tämän teeman perusteella organisaation itsearvioinnin vaikuttavuus perustuu itsearvioinnin käyttämiseen sekä tulosyksikön sisäisenä että johdon strategisen tason itsearviointina osana tulosjohtamista. Samoin teema ”ollaanko samaa perhettä” löytyy jokaisesta tutkimuskohteena olleesta tulosyksiköstä. Teeman perusteella vaikuttavuus perustuu siihen, että organisaation itsearvioinnin tilaisuus koetaan sosiaalisena tapahtumana ja organisaation itsearviointi vahvistaa työntekijöiden osallistumista ja sitoutumista toiminnan laadun parantamiseen. Vaikuttavuuden teemoissa ”poistetaan kivi kengästä, ja hiertäminen loppuu siihen”, ”strateginen valinta” ja ”henkilöstön työhyvinvoinnin edistäminen” organisaation itsearvioinnin vaikuttavuus on tulosyksikkökohtainen. Organisaation itsearvioinnista haetaan vaikuttavuutta organisaation itsearvioinnista saatavien tulosten nopealla toimeenpanolla. Vaikuttavuuteen pyritään systemaattisella eri organisaation tasoilla tehtävillä toiminnan kuvauksilla, mihin liittyy laatupalkinnon hakeminen. Vaikuttavuuteen voidaan myös päästä työpistelähtöisesti henkilöstön johtamisen ja hallinnon kautta. Vaiheistettua organisaation itsearviointia voidaan käyttää osana tulosjohtamista. Muita keskeisiä tutkimustuloksia ovat organisaation itsearvioinnin välittömät ja välilliset vaikutukset. Tutkimuksen tulosten perusteella teen suositukset organisaation itsearvioinnin johtamiskäytännöistä ja organisaation itsearvioinnin vaiheistuksesta osana tulosyksikön tulosjohtamista. Kolmas suositus käsittää organisaation itsearvioinnin käytön palautejärjestelmänä.

Fast and sensitive supercritical fluid chromatography - tandem mass spectrometry multi-class screening method for the determination of doping agents in urine.

This study shows the possibility offered by modern ultra-high performance supercritical fluid chromatography combined with tandem mass spectrometry in doping control analysis. A high throughput screening method was developed for 100 substances belonging to the challenging classes of anabolic agents, hormones and metabolic modulators, synthetic cannabinoids and glucocorticoids, which should be detected at low concentrations in urine. To selectively extract these doping agents from urine, a supported liquid extraction procedure was implemented in a 48-well plate format. At the tested concentration levels ranging from 0.5 to 5 ng/mL, the recoveries were better than 70% for 48-68% of the compounds and higher than 50% for 83-87% of the tested substances. Due to the numerous interferences related to isomers of steroids and ions produced by the loss of water in the electrospray source, the choice of SFC separation conditions was very challenging. After careful optimization, a Diol stationary phase was employed. The total analysis time for the screening assay was only 8 min, and interferences as well as susceptibility to matrix effect (ME) were minimized. With the developed method, about 70% of the compounds had relative ME within the range ±20%, at a concentration of 1 and 5 ng/mL. Finally, limits of detection achieved with the above-described strategy including 5-fold preconcentration were below 0.1 ng/mL for the majority of the tested compounds. Therefore, LODs were systematically better than the minimum required performance levels established by the World anti-doping agency, except for very few metabolites.

Sheep production as a Senecio spp. control tool

Since poisoning by Senecio spp. is one of the main causes of cattle death in southern Brazil, control of these plants is a priority for the local livestock production. After the pasture has been mowed, grazing by 16 sheep was efficient for controlling Senecio brasiliensis and Senecio madagascariensis populations in a 5.5-hectare area that had long been severely infested with these species. A total of 28,629 plants among S. brasiliensis (flower-of-souls, 10,122) and S.madagascariensis (fireweed, 18,507) were almost completely eliminated in a two-year period. The number of sheep was kept at 3.0 stock units/ha, but a variable number of cattle were temporarily stocked according to pasture availability. The major sanitary practice applied to the sheep was anthelmintic administration. Liver biopsies taken from sheep and cattle before and after experimental period didn't reveal any change associable with seneciosis. The performance levels of the sheep were comparable to those observed in flocks managed under traditional extensive grazing systems in southern Brazil.

Hallinto-oikeuksien suorituskyvynmittauksen ja tavoiteasetannan kehittämismahdollisuudet

Suomen hallintotuomioistuinten mittaristotyöryhmä on laatinut oikeusasioiden hallintaa parantavan käsittelyn viivästymisestä varoittavan hälytysjärjestelmän sekä luokitellut asiat työmäärään perustuen. Luokille on laadittu työmäärää kuvaavat painokertoimet. Tämän diplomityön tavoitteena on tutkia asiahallintajärjestelmään tehtyjen uudistusten mahdollistamia suorituskyvynmittauksen ja tavoiteasetannan kehittämismahdollisuuksia asiavirtauksen näkökulmasta. Tavoitteeseen pääsemiseksi selvitetään työmääräpainotuksen vaikutuksia hallinto-oikeuksien suorituskyvyn tunnuslukuihin sekä analysoidaan hallinto-oikeuksien suorituskykyä työmääräpainotuksella vuosina 2009-2012. Raportti sisältää tutkimuksen aihetta käsittelevän teoriakatsauksen ja kohdeorganisaatiota tutkivan empiirisen osuuden. Empiirinen osuus perustuu vahvasti kvantitatiiviseen tutkimukseen. Tutkimuksen tuloksena havaittiin, että työmääräpainotus kaventaa hallintooikeuksien välisiä suorituskykyeroja, mutta huomattavia eroja esiintyy myös työmääräpainotuksilla tarkasteltuna. Hallinto-oikeuksien suorituskyvyissä esiintyy eroja sekä oikeuksien välillä että oikeuksien sisällä eri vuosina. Analysoimalla nykyisiä suorituskyvyn mittauksen ja tavoiteasetannan käytäntöjä, voidaan esittää neljä kehittämisen painopistettä: 1) tavoiteasetannan tekeminen pidemmälle tähtäimelle, 2) mittauksen ja seurannan painopiste toteutuneesta ennakointiin, 3) suorituskyvyn tunnusluvut vastaamaan työmääräpainotusta ja 4) tavoitetasojen yhdenmukaistaminen. Näiden havaittujen kehittämispainopisteiden ja suorituskykyanalyysien pohjalta luotiin vaihtoehtoinen tapa mitata suorituskykyä ja asettaa tavoitteita. Kehittämisehdotusta havainnollistettiin erilaisten skenaarioiden avulla. Työ tarjoaa hyödyllistä tietoa hallinto-oikeuksien suorituskyvystä ja siitä millaisia mahdollisuuksia asianhallinnan uudistukset tuovat hallinto-oikeuksien suorituskyvyn kehittämiseen ja seurantaan.

Design Space Exploration for MPSoC Architectures

Multiprocessor system-on-chip (MPSoC) designs utilize the available technology and communication architectures to meet the requirements of the upcoming applications. In MPSoC, the communication platform is both the key enabler, as well as the key differentiator for realizing efficient MPSoCs. It provides product differentiation to meet a diverse, multi-dimensional set of design constraints, including performance, power, energy, reconfigurability, scalability, cost, reliability and time-to-market. The communication resources of a single interconnection platform cannot be fully utilized by all kind of applications, such as the availability of higher communication bandwidth for computation but not data intensive applications is often unfeasible in the practical implementation. This thesis aims to perform the architecture-level design space exploration towards efficient and scalable resource utilization for MPSoC communication architecture. In order to meet the performance requirements within the design constraints, careful selection of MPSoC communication platform, resource aware partitioning and mapping of the application play important role. To enhance the utilization of communication resources, variety of techniques such as resource sharing, multicast to avoid re-transmission of identical data, and adaptive routing can be used. For implementation, these techniques should be customized according to the platform architecture. To address the resource utilization of MPSoC communication platforms, variety of architectures with different design parameters and performance levels, namely Segmented bus (SegBus), Network-on-Chip (NoC) and Three-Dimensional NoC (3D-NoC), are selected. Average packet latency and power consumption are the evaluation parameters for the proposed techniques. In conventional computing architectures, fault on a component makes the connected fault-free components inoperative. Resource sharing approach can utilize the fault-free components to retain the system performance by reducing the impact of faults. Design space exploration also guides to narrow down the selection of MPSoC architecture, which can meet the performance requirements with design constraints.

Development and Effect Analysis of the Asteri Consultative Auditing Process - Safety and Security Management in Educational Institutions

The Finnish legislation requires for a safe and secure learning environment. However, the comprehensive, risk based safety and security management (SSM) and the management commitment in the implementation and development of the SSM are not mentioned in the legislation. Multiple institutions, operators and researchers have studied and developed safety and security in educational institutions over the past decade. Typically the approach has been fragmented and without bringing up the importance of the comprehensive SSM. The development needs of the safety and security operations in universities have been studied. However, in universities of applied sciences (UASs) and in elementary schools (ESs), the performance level, strengths and weaknesses of the comprehensive SSM have not been studied. The objective of this study was to develop the comprehensive, risk based SSM of educational institutions by developing the new Asteri consultative auditing process and study its effects on auditees. Furthermore, the performance level in the comprehensive SSM in UASs and ESs were studied using Asteri and the TUTOR model developed by the Keski-Uusimaa Department for Rescue Services. In addition, strengths, development needs and differences were identified. In total, 76 educational institutions were audited between the years 2011 and 2014. The study is based on logical empiricism, and an observational applied research design was used. Auditing, observation and an electronic survey were used for data collection. Statistical analysis was used to analyze the collected information. In addition, thematic analysis was used to analyze the development areas of the organizations mentioned by the respondents in the survey. As one of the main contributions, this research presents the new Asteri consultative auditing process. Organizations with low performance levels on the audited subject benefit the most from the Asteri consultative auditing process. Asteri may be usable in many different types of audits, not only in SSM audits. As a new result, this study provides new knowledge on attitudes related to auditing. According to the research findings, auditing may generate negative attitudes and the auditor should take them into account when planning and preparing for audits. Negative attitudes can be compensated by producing added value, objectivity and positivity for the audit and, thus, improve the positive effects of auditing on knowledge and skills. Moreover, as the results of this study shows, auditing safety and security issues do not increase feelings of insecurity, but rather increase feelings of safety and security when using the new Asteri consultative auditing process with the TUTOR model. The results showed that the SSM in the audited UASs was statistically significantly more advanced than that in the audited ESs. However, there is still room for improvement in the ESs and the UASs as the approach to the SSM was fragmented. It can be assumed that the majority of Finnish UASs and ESs do not likely meet the basic level of the comprehensive, risk based the SSM.
