Alueellinen energiatehokkuusmalli

Energian kulutus ja siitä aiheutuvat haittavaikutukset lisääntyvät globaalisti, minkä johdosta tarve uusille toimintamalleille ja ajatustavoille on merkittävä. Yksi mahdollisuus vastata energian kulutuksen kasvuun on lisätä energiatehokkuutta. Energiatehokkuudella voidaan vähentää energian käytöstä aiheutuvia päästöjä kustannustehokkaasti. Tässä työssä tarkastellaan energiatehokkuutta ja sen lisäämistä alueellisella tasolla. Työssä käsitellään menetelmiä ja keinoja alueellisen energiatehokkuuden lisäämiseksi esimerkiksi kaupungeissa ja yhteisöissä. Työssä esitetään alueellisen energiatehokkuuden arviointimalli, jolla voidaan määrittää alueellisen energiatehokkuuden toteutumista ja energiaratkaisujen kannattavuutta ympäristön kannalta. Malli sisältää matemaattisesti määritettäviä tunnuslukuja, jotka kuvaavat ympäristövaikutuksia. Mallia sovelletaan Lohjan alue-tarkasteluun, jossa mallin pohjalta esitetään vaihtoehtoja energiatehokkuuden lisäämiseksi. Voidaan todeta, että arviointimalli on käyttökelpoinen ja sillä voidaan havainnol-listaa alueellista energian käyttöä ja sen energiatehokkuutta. On kuitenkin huomattava, että malli huomioi lähinnä vain ympäristövaikutuksia ja sisältää virheläh-teitä johtuen esimerkiksi käytettävissä olevan tiedon määrästä.

This review highlights historically important and recent papers on practical and theoretical aspects related to these issues. Namely, basic properties and peculiarities of such materials related to both their design and wave propagation in them, experimental verification of predictions theoretically made for them, possible practical applications and prospects in this area are considered.

Globaalin toimintaympäristön vaikutukset johdon laskentatoimen asiantuntijan työnkuvassa

Tutkimuksen tavoitteena oli selvittää, millaisia globalisaation aiheuttamia vaikutuksia näkyy suomalaisessa johdon laskentatoimessa ja johdon laskentatoimen asiantuntijoiden, eli controllereiden, työnkuvissa. Oli tärkeää selvittää, ovatko kansainväliset tekijät tuoneet jo liiallista haastavuutta controllerin työhön ja odotetaanko heiltä kenties jo liikaa. Teoriaosuudessa tutkittiin johdon laskentatoimea ja controller-toiminnon kehittymistä, sekä controllereilta vaadittavia ominaisuuksia ja piirteitä. Lisäksi globalisaatiota ja sen aiheuttamia vaikutuksia suomalaiseen johdon laskentatoimeen käytiin läpi. Tutkimus oli kvalitatiivinen ja toteutettiin haastattelemalla kahdeksaa suomalaista johdon laskentatoimen asiantuntijaa, jotka työskentelivät kansainvälisissä yhtiöissä useilla eri toimialoilla. Tutkimus osoitti kuinka kansainvälisestä ja laajasta alasta on kyse johdon laskentatoimesta puhuttaessa. Suuri joukko globaaleja tekijöitä vaikuttaa jatkuvasti controllereihin. Näiden luokittelu teemoittain osoittautui haastavaksi tehtäväksi ja on mahdotonta luoda kattava lista kaikista kansainvälisyyden tuomista vaikutuksista. Tärkeää oli havaita, ettei controller-toiminnon laajuutta koeta negatiivisena vaan ennemminkin sopivan haasteellisena asiana ja mielenkiinnon ylläpitäjänä.

Balanced Scorecardin ja palkitsemisen hyödyntäminen palvelutuotannon johtamisessa

Suorituskyvyn johtamista on tutkittu paljon teollisuustalouden näkökulmasta. Sen sijaan palvelutuotannon näkökulmasta katsottuna tutkimustyö on vasta aluillaan. Iso osa yritysten liiketoiminnasta muodostuu palvelujen tuottamisesta, joten palvelutuotannon merkitys on tänä päivänä varsin keskeisessä roolissa. Suorituskyvyn johtaminen tarvitsee rinnalleen kannustavia palkitsemismalleja. Oikein toteutettuna palkitseminen ohjaa strategian mukaisiin tavoitteisiin ja parantaa organisaation tuloksellisuutta. Palkitseminen tulee kuitenkin nähdä riittävän monipuolisena kokonaisuutena. Parhaimmillaan se sitouttaa, motivoi ja kannustaa työntekijöitä entistä parempiin suorituksiin. Epäonnistuessaan sillä on monia negatiivissa vaikutuksia. Se saattaa lisätä epäoikeudenmukaisuuden tunnetta, jolloin työilmapiiri heikkenee sekä poissaolot ja vaihtuvuus lisääntyvät. Tässä tutkimuksessa on keskitytty palvelutuotannon organisaation tutkimiseen. Tutkimuksessa selvitettiin, mitä tekijöitä tulee huomioida logistiikkasektorin palvelutuotannon organisaation onnistumista mitattaessa ja palkitessa. Tutkimus toteutettiin case-organisaatiossa konstruktiivista tutkimusotetta hyödyntäen. Tiedonkeruumenetelmänä käytettiin puolistrukturoituja haastatteluja. Tutkimuksessa rakennettiin suorituskykyä mittaava mallimittaristo ja suorituskykyä tukeva palkitsemismalli. Mittariston viitekehyksenä käytettiin Balanced Scorecardia. Tulosten perusteella voidaan todeta, että palvelutuotannon erityispiirteet tulee huomioida mittaristoa rakennettaessa. Asiakkaan rooli tulee palvelutuotannossa korostuneesti esiin. Lisäksi on huomioitava kohdeorganisaation omat strategiset tavoitteet. Mittaristoon tulee ottaa tulosmittareita, ennakoivia mittareita ja ympäristön muutosta selittäviä mittareita. Palkitsemismalleja tulee tutkia sekä aineellisen että aineettoman palkitsemisen näkökulmista. Aineellisessa palkitsemisessa tulee huomioida suoritukseen perustuva palkitseminen. Aineettomassa palkitsemisessa puolestaan on huomioitava yksilölliset tarpeet, jotka perustuvat henkilökohtaisiin ominaisuuksiin ja arvomaailmaan.

Social Solidarity and Fear of Crime - Community and Individual Approaches in Responses to Mass Violence after School Shootings

The aim of this study was to examine community and individual approaches in responses to mass violence after the school shooting incidents in Jokela (November 2007) and Kauhajoki (September 2008), Finland. In considering the community approach, responses to any shocking criminal event may have integrative, as well as disintegrative effects, within the neighborhood. The integration perspective argues that a heinous criminal event within one’s community is a matter of offence to collectively held feelings and beliefs, and increases perceived solidarity; whereas the disintegration perspective suggests that a criminal event weakens the social fabric of community life by increasing fear of crime and mistrust among locals. In considering the individual approach, socio-demographic factors, such as one’s gender, are typically significant indicators, which explain variation in fear of crime. Beyond this, people are not equally exposed to violent crime and therefore prior victimization and event related experiences may further explain why people differ in their sensitivity to risk from mass violence. Finally, factors related to subjective mental health, such as depressed mood, are also likely to moderate individual differences in responses to mass violence. This study is based on the correlational design of four independent cross-sectional postal surveys. The sampling frames (N=700) for the surveys were the Finnish speaking adult population aged 18–74-years. The first mail survey in Jokela (n=330) was conducted between May and June 2008, approximately six months from the shooting incident at the local high-school. The second Jokela survey (n=278) was conducted in May–June of 2009, 18 months removed from the incident. The first survey in Kauhajoki (n=319) was collected six months after the incident at the local University of Applied Sciences, March– April 2009, and the second (n=339) in March–April 2010, approximately 18 months after the event. Linear and ordinal regression and path analysis are used as methods of analyses. The school shootings in Jokela and Kauhajoki were extremely disturbing events, which deeply affected the communities involved. However, based on the results collected, community responses to mass violence between the two localities were different. An increase in social solidarity appears to apply in the case of the Jokela community, but not in the case of the Kauhajoki community. Thus a criminal event does not necessarily impact the wider community. Every empirical finding is most likely related to different contextual and event-specific factors. Beyond this, community responses to mass violence in Jokela also indicated that the incident was related to a more general sense of insecurity and was also associating with perceived community deterioration and further suggests that responses to mass violence may have both integrating and disintegrating effects. Moreover, community responses to mass violence should also be examined in relation to broader social anxieties and as a proxy for generalized insecurity. Community response is an emotive process and incident related feelings are perhaps projected onto other identifiable concerns. However, this may open the door for social errors and, despite integrative effects, this may also have negative consequences within the neighborhood. The individual approach suggests that women are more fearful than men when a threat refers to violent crime. Young women (aged 18–34) were the most worried age and gender group as concerns perception of threat from mass violence at schools compared to young men (aged 18–34), who were also the least worried age and gender group when compared to older men. It was also found that concerns about mass violence were stronger among respondents with the lowest level of monthly household income compared to financially better-off respondents. Perhaps more importantly, responses to mass violence were affected by the emotional proximity to the event; and worry about the recurrence of school shootings was stronger among respondents who either were a parent of a school-aged child, or knew a victim. Finally, results indicate that psychological wellbeing is an important individual level factor. Respondents who expressed depressed mood consistently expressed their concerns about mass violence and community deterioration. Systematic assessments of the impact of school shooting events on communities are therefore needed. This requires the consolidation of community and individual approaches. Comparative study designs would further benefit from international collaboration across disciplines. Extreme school violence has also become a national concern and deeper understanding of crime related anxieties in contemporary Finland also requires community-based surveys.

Evaluation of novel programs in health counseling – their effectiveness in the oral health of young children, and their acceptance by parents and professionals in public dental service.

Aim and design: To evaluate family-based health counseling for young children, and to study the significance of adding parental self-care or the training of professionals to the programs. The effectiveness and acceptability of the programs were evaluated by comparing two new programs with an earlier one. Subjects and methods: The study was carried out in Vantaa, which was divided into three study areas. The subjects consisted of children born in 2008, particularly fi rstborn children, while children born in 2006 formed the historical control. The fi rst of the new programs emphasized oral hygiene and use of fl uoride, and the second program focused on proper diet and use of xylitol. The main outcome measure was mutansstreptococci (MS) in the dental biofi lm of two-year-olds, and the opinions of parents and dental professionals were evaluated using questionnaires. Results: The programs found wide acceptance among dental professionals. There were no group-related differences found in the MS scores of the two-year-olds. However, all groups combined, father’s advanced level of education and child’s proper use of xylitol were associated with negative MS scores. In the opinion of parents, the oral healthcare guidance at least somewhat met their expectations. Conclusions: The present fi ndings suggest that providing training and support for professionals in health education is important. The addition of parental self-care to supplement programs aimed at young children does not improve the program, although it may improve parental readiness to change their own health habits. Counseling for families might be best carried out through a routine patient-centered program.

Modularity in Health and Social Services: Perspectives on Organization and Management

Organizations that provide health and social services operate in a complex and constantly changing environment. Changes occur, for example, in ageing, technology and biotechnology, and customers’ expectations, as well as the global economic situation. Organizations typically aim to adapt the changes by introducing new organizational structures and managerial practices, such as process and lean management. Only recently has there been an interest in evaluating whether organizations providing health and social services could apply modularity in order to respond to some of the changes. The concept of modularity originates from manufacturing, but is applied in many other disciplines, such as information technology and logistics. However, thus far, the literature concerning modularity in health and social services is scarce. Therefore the purpose of this thesis is to increase understanding concerning modularity and the possibilities to apply modularity in the health and social services context. In addition, the purpose is to shed light on the viewpoints that are worth taking into account when considering the application of modularity in the health and social services context. The aim of the thesis is to analyze the way in which the modular structures are applied in the health and social services context and to analyze what advantages and possible barriers, as well as managerial concerns, might occur if modularity is applied in the health and social services context. The thesis is conducted by using multiple methods in order to provide a broad aspect to the topic. A systematic literature review provided solid ground for pre-understanding the topic and supported the formulation of the research questions. Theoretical reasoning provided a general overview of the special characteristics of the health and social services context and their effect on application of modularity. Empirical studies concentrated on managerial concerns of modularity particularly from the perspective of health and social services for the elderly. Results of the thesis reveal that structures in products, services, processes, and organizations are rather modular in health and social services. They can be decomposed in small independent units, while the challenges seem to occur especially in the compatibility of the services. It seems that health and social services managers have recognized this problem and they are increasingly paying attention to this challenge in order to enhance the flexible compatibility of services. Advantages and possible barriers of modularity are explored in this thesis, and from the theoretical perspective it could be argued that modularity seems to be beneficial in the context of health and social services. In fact, it has the potential to alleviate several of the challenges that the health and social services context is confronting. For example, modular structures could support organizations in their challenging task to respond to customers’ increasing demand for heterogeneous services. However, special characteristics of the health and social services context create barriers and provide significant challenges in application of modularity. For example, asymmetry of information, negative externalities, uncertainty of demand, and rigid regulation prevent managers from extensively drawing benefits from modularity. Results also reveal that modularity has managerial implications in health and social service. Modularity has the potential to promote and support new service development and outsourcing. Results also provide insights into network management and increases managerial understanding of different network management strategies. Standardization in health and social services is extensive due to legislation and recommendations. Modularity provides alternative paths to take an advantage of standardization while still ensuring the quality of the services. Based on this thesis, it can be concluded, both from a theoretical perspective and from empirical results concerning modularity in health and social services, that modularity might fit well and be beneficial. However, the special characteristics of the health and social services context prevent some of the benefits of modularity and complicate its application. This thesis contributes to the academic literature on the organization and management of health and social services by describing modularity as an alternative way for organizing and managing health and social services. In addition, it contributes to the literature of modularity by exploring the applicability of modularity in the context of health and social services. It also provides practical contribution to health and social services managers by evaluating the pros and cons of modularity when applied to health and social services.

Life-related negative customer emotions in real estate agent encounters

The goal of this study was to explore how do customers’ life-related negative emotions affect real estate business. This was divided into two research questions: 1. What life-related negative emotions can be recognised in real estate customer encounters? 2. How do the recognised emotions affect customer encounters and the realtor’s work? 3. How can the realtor take the emotions into account in customer service? The theoretical background consists of two main lines of study: emotions and customer encounters. A wide literary review on emotions research was conducted from a cognitive psychology point of view, focusing on negative emotions. Emotions research was then combined into the field of customer encounters. Qualitative study was chosen as the methodological basis of the study. Empirical material of this study was collected through in-depth interviews with 13 successful Finnish real estate agents. Narrative research was used as a method for the study. Four life-related emotion categories were recognized in real estate customer encounters: sadness, anger, anxiety and shame. These emotions rose from issues varying from death of a close one to divorce and from major changes in life stages to deep emotional attachment to an old home. The study also found that these incidental negative emotions do affect customer encounters and realtors’ work. The emotions affected the decision making of customers and sometimes overshadowed reason. Some emotions made the customer passive and slow to make any decisions, while others made their decision making fast and hasty. Even though the incidental emotions might not have had anything to do with the real estate deal, they could affect the outcome of the customer encounter and the whole real estate deal. Interestingly enough, the study found that not all successful real estate agents knowingly serve customers in an emotional level. The study does, however, suggest that in fact it may be an ethical decision of the customer server to take into account the emotional state of the customer. Attending to the emotional side of customers does not only increase pleasantness of the customer encounter, but may improve and balance customer decision making and prevent hasty decisions possibly leading to improved customer satisfaction. This study also gave practical managerial implications to customer service providers on how negative incidental emotions can be attended to in a customer encounter. This study could be useful not only to real estate agents, but also in other types of customer service, especially with vulnerable populations or other types of home-related business.
