Initial growth and competitive ability of yellow nutsedge and irrigated rice

Weeds cause significant reduction in the irrigated rice crop yield. Cyperus esculentus (yellow nutsedge) is adapted to irrigate environment. Information on the competitive ability of the weed to the culture, and their environmental adaptation, are scarce. In this study, we sought to determine the initial growth and competitive ability of yellow nutsedge and irrigated rice, as a function of cultivar growth cycle. Initial growth and competition studies were conducted in a randomized complete design in a greenhouse in the agricultural year 2010/11. For the initial growth study, the treatments consisted of a factorial combination of a biotype of yellow nutsedge and two rice cultivars in the function of the vegetative cycle (BRS Querência: early cycle - IRGA 424: intermediate cycle) and six evaluation times (10, 20, 30, 40, 50, and 60 days after emergence). Were evaluated: plant height, leaf area, aboveground dry biomass and root dry biomass. In the competitive ability study in the replacement series, the cultivar BRS Querência (early cycle) and yellow nutsedge were utilized and tested in different proportions of competition (100:0, 75:25, 50:50, 25:75, and 0:100). Were evaluated leaf area and aboveground dry biomass. In general, rice cultivars have an adaptive value equivalent to yellow nutsedge. IRGA 424 cultivar has less height than weed, becoming the weed control more important in this cultivar. For rice crop, intraspecific competition is more important, whereas for the weed, interspecific competition is the most pronounced.

The Relationship of Organizational Culture, Employee Motivation and Innovativeness: Evidence from Finnish Technology Industries

The purpose of this thesis is to analyze the effects of tangible and intangible incentives on the dimensions of motivation and organizational innovativeness in the context of different organizational cultures. Theory suggests that an antecedent of innovativeness is individual creativity of employees, which is influenced by intrinsic motivation, flexible organizational structures, and transformational leadership. Empirical evidence for this research is derived from 424 respondents representing technology-driven industries in Finland. Data is collected through an online questionnaire and analyzed using SPSS statistics software. The results imply that intangible incentives and intrinsic motivation have an important role in determining organizational innovativeness. The positive relationships of intangible incentives, intrinsic motivation and innovativeness seem to be higher in flexible organizational cultures. As practical implications, managers should foster flexible organizational cultures that highlight employee empowerment. The motivating power of non-financial intrinsic incentives and recognition of good work should not be undermined when compared to tangible monetary rewards.

Adaptive value of ryegrass biotypes with low-level resistance and susceptible to the herbicide fluazifop and competitive ability with the wheat culture

Ryegrass is the main weed in wheat crop, causing yield loss due to competition by environmental resources. The objectives of this study were to estimate the fitness cost of ryegrass biotypes with low-level resistance and susceptible to fluazifop and to investigate the relative competitive ability of these biotypes between themselves and against the crop. Thus, fitness cost and competitive ability experiments were conducted under greenhouse conditions. For the fitness cost experiments, the low-level resistant ryegrass biotypes and those susceptible to fluazifop were used. For competitive ability, the treatments were arranged in a replacement series, with five proportions of the wheat cultivar FUNDACEP Horizonte and the low-level resistant and susceptible ryegrass biotypes 100:0, 75:25, 50:50, 25:75 and 0:100. Competitive analysis was carried out through diagrams applied to the replacement experiments and use of relative competitiveness indices. Variables evaluated were plant height, in the fitness cost experiment, and leaf area and shoot dry biomass in both experiments. The ryegrass biotypes show overall similar fitness cost and competitive ability. The wheat cultivar FUNDACEP Horizonte is superior in competitive ability to the ryegrass biotype with low-level resistance and equivalent to the susceptible biotype.

Does the resistance to glyphosate herbicide affect the competitive ability of ryegrass with soybean?

The objective this work was to investigate the competitive ability between resistant and susceptible ryegrass biotypes and of these with soybean crop. Four experiments were carried under greenhouse, in a completely randomized design with four replications, in 2011 and 2012. Treatments were arranged in additive series and replacement series assay. In each series, the proportions among ryegrass resistant and susceptible plants related to soybean were: 100:0, 75:25, 50:50, 25:75 e 0:100. Leaf area and shoot dry mass were evaluated. Competitiveness statistical analysis consisted in applying diagrams to the replacement series and alternative interpretations of the competitiveness indexes. The soybean crop had equivalent competitiveness to the susceptible ryegrass biotype and inferior to the resistant biotype, while the biotypes, both susceptible and resistant to glyphosate, present equivalent competitive ability. In general, the intraspecific competition is more harmful to ryegrass when in competition with soybean, while interspecific competition is predominant for culture.

Business intelligence and management control

The purpose of this study is to explore the possibilities of utilizing business intelligence (BI)systems in management control (MC). The topic of this study is explored trough four researchquestions. Firstly, what kind of management control systems (MCS) use or could use the data and information enabled by the BI system? Secondly, how the BI system is or could be utilized? Thirdly, has BI system enabled new forms of control or changed old ones? The fourth and final research question is whether the BI system supports some forms of control that the literature has not thought of, or is the BI system not used for some forms of control the literature suggests it should be used? The study is conducted as an extensive case study. Three different organizations were interviewed for the study. For the theoretical basis of the study, central theories in the field of management control are introduced. The term business intelligence is discussed in detail and the mechanisms for governance of business intelligence are presented. A literature analysis of the uses of BI for management control is introduced. The theoretical part of the study ends in the construction of a framework for business intelligence in management control. In the empirical part of the study the case organizations, their BI systems, and the ways they utilize these systems for management control are presented. The main findings of the study are that BI systems can be utilized in the fields suggested in the literature, namely in planning, cybernetic, reward, boundary, and interactive control. The systems are used both as the data or information feeders and directly as the tools. Using BI systems has also enabled entirely new forms of control in the studied organizations, most significantly in the area of interactive control. They have also changed the old control systems by making the information more readily available to the whole organization. No evidence of the BI systems being used for forms of control that the literature had not suggested was found. The systems were mostly used for cybernetic control and interactive control, whereas the support for other types of control was not as prevalent. The main contribution of the study to the existing literature is the insight provided into how BI systems, both theoretically and empirically, are used for management control. The framework for business intelligence in management control presented in the study can also be utilized in further studies about the subject.

Assessing the Competitive Ability of Rhynchosia capitata; an Emerging Summer Weed in Asia

Rhynchosia capitata is a newly emerging threatening weed of summer crops in many Asian countries. We conducted 2-yr experiments to evaluate R. capitata competition with mungbean under irrigated conditions. Rhynchosia capitata was allowed to compete with mungbean for 0, 3, 4, 5, 6, 7 weeks after planting and for full crop season. The competitive ability of R. capitata was assessed by measuring its dry weight, micro and macro nutrient contents and uptake; and its effects on mungbean growth and yield parameters. The results showed that full season weed competition produced highest dry weight of R. capitata and its macro and micronutrient contents and uptake. Yield and yield components of mungbean decreased in a linear fashion with increase in competition period of Rhynchosia capitata. Full season competition of R. capitata reduced the seed yield of mungbean by 49% and 46% during 2011 and 2012 respectively. In conclusion, damaging effect of R. capitata intrusion on mungbean yield is associated with duration of its presence in crop, accumulation of dry matter and the nutrient uptake by R. capitata, which otherwise should be available to crop.

COMPETITIVE ABILITY OF CANOLA HYBRIDS WITH WEEDS

ABSTRACTThe objective of the study was to assess the relative competitive ability of canola hybrids in the presence of turnip (Raphanus sativus) and ryegrass (Lolium multiflorum) in different ratios of plants in the mixture. The experiments were conducted in a greenhouse, in a completely randomized design with four replications. Treatments were arranged in ratios of canola against turnip or ryegrass: 100:0, 75:25, 50:50, 25:75 and 0:100. Competitive analysis of the species was accomplished by means of diagrams usually applied to replacement series and also by the relative competitiveness indices. Fifty days after the emergence of the species, measurements of leaf area and shoot dry mass were performed. There was a competition between canola hybrids and weeds, with reduction for all variables. There was a differential competitive ability among canola hybrids in the presence of turnip and/or ryegrass. Canola hybrid Hyola 433 was more competitive in the presence of turnip than Hyola 61, 76 and 571 CL. Hyola 61, 76, 433 and 571 CL do not differ in terms of competition ability when growing with ryegrass.

Emotional intelligence and multicultural project leadership in Finnish-Chinese MNC context

The main goal of this thesis was to examine how the emotional intelligence skills and multicultural project leadership style of a project manager interrelate and affect the success of a project. The research methods used are literature review in theoretical part of the thesis and semi-structured interviews in empirical part of the thesis. This study is a single case study i.e. one case company was selected to be the secondary level of analysis. Within the case company, four project managers were selected as research units to form the primary level of analysis. Literature review formed the basis for the empirical research and the interview questions were derived from the literature. Findings from the interviews were mirrored against the literature review findings, based on which both conclusions and generalisations could be made. Thus, both deductive and inductive methods were utilised to get more complete picture about the research topic. In the first part of the literature review the general leadership theories and the project leadership terminology are introduced as a background for the concept of emotional intelligence and the integrated leadership model. Emotional intelligence and its interrelation to different leadership concepts are discussed during the literature review. Chinese cultural aspects affecting the way of making business, and the multicultural leadership styles of the Finnish project managers are introduced in the following part of the literature review. It was found that the most successfully used multicultural leadership styles in Finnish-Chinese context are synergistic and polycentric, and these require emotional intelligence skills. In the empirical part on this thesis the findings from the semi-structured interviews are introduced, discussed and analysed. Interviews were done in private meeting rooms, and they were recorded and transcripted to add reliability and validity. Although the sample was only four project managers, the results show that the sample is quite saturated as the responses to several questions followed the same pattern. It was found that Finnish project managers in the case company are democratic and take cultural differences into account in their project leadership. Both synergistic and polycentric leadership styles are used with Chinese team members. Emotional intelligence capabilities and the emphasis of those differ a bit depending on the interviewee. Though, the results show that EI skills and the multicultural project leadership style used in Chinese context are interrelated. The findings from the literature review and the empirical research in this thesis are similar. Though, there is need for further research as the sample was small, and this thesis is a single case study. It is recommendable to make a multi-company study with larger sample of project managers. Also multi-industry perspective is recommendable for further research.

Strategic narratives and competitive advantage : do winners speak differently?

Concepts, models, or theories that end up shaping practices, whether those practices fall in the domains of science, technology, social movements, or business, always emerge through a change in language use. First, communities begin to talk differently, incorporating new vocabularies (Rorty, 1989), in their narratives. Whether the community’s new narratives respond to perceived anomalies or failures of the existing ones (Kuhn, 1962) or actually reveal inadequacies by addressing previously unrecognized practices (Fleck, 1979; Rorty, 1989) is less important here than the very phenomena that they introduce differences. Then, if the new language proves to be useful, for example, because it helps the community solve a problem or create a possibility that existing narratives do not, the new narrative will begin circulating more broadly throughout the community. If other communities learn of the usefulness of these new narratives, and find them sufficiently persuasive, they may be compelled to test, modify, and eventually adopt them. Of primary importance is the idea that a new concept or narrative perceived as useful is more likely to be adopted. We can expect that business concepts emerge through a similar pattern. Concepts such as “competitive advantage,” “disruption,” and the “resource based view,” now broadly known and accepted, were each at some point first introduced by a community. This community experimented with the concepts they introduced and found them useful. The concept “competitive advantage,” for example, helped researchers better explain why some firm’s outperformed others and helped practitioners more clearly understand what choices to make to improve the profit and growth prospects of their firms. The benefits of using these terms compelled other communities to consider, apply, and eventually adopt them as well. Were these terms not viewed as useful, they would not likely have been adopted. This thesis attempts to observe and anticipate new business concepts that may be emerging. It does so by seeking to observe a community of business practitioners that are using different language and appear to be more successful than a similar community of practitioners that are have not yet begun using this different language as extensively. It argues that if the community that is adopting new types of narratives is perceived as being more successful, their success will attract the attention of other communities who may then seek to adopt the same narratives. Specifically, this thesis compares the narratives used by a set of firms that are considered to be performing well (called Winners) with those of set of less-successful peers (called Losers). It does so with the aim of addressing two questions: - How do the strategic narratives that circulate within “winning” companies and their leaders differ from those circulating within “losing” companies and their leaders? - Given the answer to the first question: what new business strategy concepts are likely to emerge in the business community at large? I expected to observe “winning” companies shifting their language, abandoning an older set of narratives for newer ones. However the analysis indicates a more interesting dynamic: “winning” companies adopt the same core narratives as their “losing” peers with equal frequency yet they go beyond these. Both “winners” and “losers” seem to pursue economies of scale, customer captivity, best practices, and securing preferential access to resources with similar vigor. But “winners” seem to go further, applying three additional narratives in their pursuits of competitive advantage. They speak of coordinating what is uncoordinated, adopting what this thesis calls “exchanging the role of guest for that of host,” and “forcing a two-front battle” more frequently than their “loser” peers. Since these “winning” companies are likely perceived as being more successful, the unique narratives they use are more likely to be emulated and adopted. Understanding in what ways winners speak differently, therefore, gives us a glimpse into the possible future evolution of business concepts.

Liiketoimintatiedonhallinnan hyödyntämisen esteet päätettäessä palveluista. Case: Kunnalliset pelastustoimen liikelaitokset ja eriytetyt taseyksiköt

Pelastuslaitosten liiketoimintatiedonhallinnalla, tietoperusteisuudella ja tietojohtamisella on tulevaisuudessa merkittävä rooli päätettäessä palveluista. Julkisen pelastustoimen kuntien liikelaitoksina ja eriytettyinä taseyksiköinä toimivien pelastuslaitosten haasteet tulevat olemaan jatkossa tehokkaiden ja vaikuttavien palveluiden strategisessa johtamisessa ja suunnittelussa. Näistä asioista päättäminen on kriittinen vaihe onnistumisen kannalta. Päätöksenteko eri tasoilla tarvitsee tuekseen toiminnasta ja palveluista kanavoitua analysoitua tietoa. Asiakastarpeesta lähtevä vaikuttavuus ja laatu korostuvat. Liiketoimintatiedonhallinta ja tietoperusteisuus haastavat pelastuslaitoksen johtamisjärjestelmän. Johtamisen kyvykkyys ja henkilöstön osaaminen ovat tietoperusteisuuden ja tiedonhallinnan keskiössä. Systemaattisen liiketoimintatiedonhallinnan ja tietoperusteisuuden erottaa perinteisestä virkamiehen tietojen hyväksikäytöstä käsitteen kokonaisvaltaisuus ja järjestelmällisyys kaikessa tiedollisessa toiminnassa. Tämä kattaa tietojärjestelmät, mittarit, prosessit, strategian suunnitelmat, asiakirjat, raportoinnin, kehittämisen ja tutkimuksen. Liiketoimin-tatiedonhallinta ja tietojohtaminen linkittävät kaiken toisiinsa muodostaen keskinäisriippuvaisen yhtenäisen järjestelmän ja kokonaisvaltaisen ymmärryksen. Tutkimukseni on laadullinen tutkimus jossa tiedon keruu ja analysointi on toteutettu toisiaan tukevilla tutkimusotteilla. Metodologia nojaa teorialähtöiseen systemaattiseen analyysiin, jossa on valikoituja osia sisällön analyysistä. Tutkimuksessa on käytetty aineisto- ja menetelmätriangulaatioita. Tutkimuksen aineisto on kerätty teemahaastatteluilla valittujen kohde pelastuslaitosten asiantuntijoilta palveluiden päätös- ja suunnittelutasolta, johtoryhmistä ja joh-tokunnista. Haastatteluja varten tutkija on tutustunut kohdepelastuslaitosten palveluita mää-rittävään tiedolliseen dokumentaatioon kuten palvelutasopäätöksiin ja riskianalyyseihin. Ai-neisto keruun kohteiksi valikoitui pääkaupunkiseudun alueen pelastuslaitokset: Helsingin kaupungin pelastuslaitos sekä Itä-, Keski- ja Länsi-Uudenmaan pelastuslaitokset. Tulosten mukaan pelastuslaitosten keskeiset liiketoimintatiedonhallinnan esteet muodostuvat johtamisen ongelmista, organisaation muutosvastarinnasta ja päätöksenteon tietoperusteen puutteesta. Nämä ilmenevät strategisen johtamisen puutteina, vaikuttavuuden mittaamisen sekä tiedon jalostamisen ongelmina. Keskeistä tiedollista yhdistävää ja linkittävää tekijää ei tunnisteta ja löydetä. Tiedollisessa liiketoimintatiedonhallinnan prosessityössä voisi olla tulos-ten mukaan mahdollisuuksia tämän tyhjiön täyttämiseen. Pelastuslaitoksille jää tulevaisuudessa valinta suunnasta johon ne haluavat edetä tiedonhal-linnan, tietojohtamisen ja tietoperusteisuuden kanssa. Tämä vaikuttaa kehitykseen ja tavoitteeseen keskeisistä palveluiden päätöksentekoa tukevista johtamis- ja tietojärjestelmistä, tietoa kokoavista ja luovista dokumenteista sekä organisaation joustavasta rakenteesta. Tietoprosessiin, tiedon prosessimaiseen johtamiseen ja systemaattiseen tiedonhallintaan meneminen vaikuttaa tutkimuksen tulosten mukaan lupaavalta mahdollisuudelta. Samalla se haastaa pelauslaitokset suureen kulttuuriseen muutokseen ja asettaa uusien vaikuttavuusmittareiden tuottaman tiedon ennakoivan hyväksynnän vaateen strategiselle suunnittelulle. Tämä vaatii pelastuslaitosten johdolta ja henkilöstöltä osaamista, yhteisymmärrystä, muutostarpeiden hyväksyntää sekä asiakkaan asettamista vaikuttavuuden keskiöön.

Johdon laskentatoimen ohjaus- ja hallintajärjestelmien hyödyntäminen yritysverkostoissa

Tutkimuksen aiheena on johdon laskentatoimen ohjaus- ja hallintajärjestelmien hyödyntäminen yritysverkostoissa. Yritysten välisten suhteiden hallinnassa käytettävät menetelmät koostuvat pääasiassa johdon laskentatoimen ja suorituskyvyn mittaamisen menetelmistä. Verkostojen ohjaus ja hallinta on tärkeää, koska se on verkostojen tehokkaan toiminnan kriittinen menestystekijä ja kilpailuedun lähde. Suorituskyvyn mittaamisella, johdon laskentatoimella ja johdon kontrollitehtävällä on keskenään riippuvuussuhteet, joiden pitäisi toimia sopusoinnussa. Suorituskyvyn mittaamisen ja johdon laskentatoimen tutkimus yritysten verkostoympäristöissä on kohtalaisen tuore ilmiö, jonka vuoksi aihealueen tutkimus on vielä varsin pirstaleista ja hajanaista. Tämän vuoksi tutkimuksen tavoite on muodostaa selkeä kokonaiskuva siitä kuinka johdon laskentatoimen ohjaus- ja hallintajärjestelmiä voidaan hyödyntää yritysverkostojen ohjauksessa ja hallinnassa. Tutkimuksessa myös selvitetään mitä haasteita näiden menetelmien hyödyntämiseen yritysverkostoissa sisältyy. Tutkimusaineistona on käytetty aikaisempia tutkimuksia sekä tutkimusta varten tehtyjä haastatteluita. Tutkimukseen haastateltiin neljästä yritysverkostosta henkilöitä, jotka vastasivat verkoston toiminnasta. Haastatteluiden avulla pyritään täydentämään kirjallisuuskatsauksen pohjalta luotua teoriaa ja selvittämään kuinka verkoston ohjaus- ja hallinta hoidetaan haastateltavissa verkostoissa, millä menetelmin ja mitä haasteita siihen liittyy. Verkostotoimintaan soveltuvien menetelmien ja suorituskykymittareiden kehittäminen on hankalaa, koska jokaisen verkoston tarpeet ja haasteet ovat erilaiset. Uusien menetelmien kehittämiselle ei nähdä tarvetta, vaan kyse on olemassa olevien menetelmien soveltamisesta verkostonäkökulmasta. Menetelmät on rakennettu yksittäisen yrityksen mittaamiseen, joten ne eivät sovellu sellaisenaan käytettäväksi verkostoihin, vaan niitä täytyy kehittää verkoston yksilöllisten tarpeiden mukaan. Tämä vaatii kuitenkin verkostolta osaamista ja halua kehittyä. Verkostojen haasteet liittyvät sekä yritystasolle että verkostotasolle. Yritysten tuottaman informaation, laskentajärjestelmien, tietotaidon, resurssien ja kehityshalun tulee olla hyvällä tasolla, jotta koko verkoston mittaaminen onnistuu luotettavasti. Lisäksi verkostotoiminta pitää sisällään laskentateknisiä, menetelmiin ja informaation vaihtamiseen liittyviä haasteita. Verkostoympäristön laskentatoimen tutkimuksessa ei ole yhtenäistä, laajasti hyväksyttyä teoriaa, koska tutkimussuuntaukset ja –tulokset ovat moniulotteisia ja vaihtelevia.
