- 2017
-
In: Proceeding of the Spring Servitization Conference. - Birmingham, UK : Aston university. - 9781854494184 ; , s. 172-181
-
Conference paper (peer-reviewed)abstract
- Purpose: Industrial services have traditionally been provided for free to support product sales. Nowadays, many manufacturers have built a profitable service business while others are struggling to improve their service profitability. Overall, most research focus on service infusion in the value proposition or servitization of the organization. Far less attention has been given to how firms start to charge for free services. The purpose of this research is to increase understanding of how manufacturers change the revenue model for individual services from free to fee. Design/Methodology/Approach: The research was performed as a two-stage research project involving a multiple case study followed by an action research project. First, a multiple case study was performed in eight firms. Data was collected through interviews and workshops with the participating firms. Second, an action research study was performed with a manufacturer working with changing the revenue model for individual services from free to fee. Findings: The current study identified a process with three stages for shifting from service for free to service for fee. The first step is turning the service from a cost center to a profit center. The second step is to create service scenarios for a service business. The third step is to implement specific strategies to break free from free service. The present research identified three specific service scenarios and four strategies to break free from free service. Originality/Value: The change of business model has been an essential step in most models for service infusion and for the transition from service for free to service for fee. The present study expands on the process on a detailed level followed by manufacturers to turn individual services from free to service for fee.

Butenes and butadiene in urban air
- 1992
-
In: The science of the total environment. ; 116, s. 195-201
-
Journal article (peer-reviewed)abstract
- Samples of urban air hydrocarbons were taken on specifically made adsorbent cartridges and analysed by gas chromatography after thermal desorption. The four isomeric butenes and 1,3-butadiene were favourably resolved and separated from the abundant alkanes on an aluminium oxide PLOT column. The concentrations of butadiene, reflecting outdoor urban exposure, were in the range of 0.5-5 micrograms/m3. An approximate 1:4 ratio was observed between butadiene and propene which both originate predominantly from vehicle exhaust. The four butenes made up approximately 50% of the propene concentration in exhaust-polluted air, with methylpropene greater than 1-butene greater than trans-2-butene greater than cis-2-butene. Petrol vapour contributed less than exhaust but about five times more to the 2-butenes than to methylpropene and 1-butene. The highest exposure levels of butadiene and butenes were consistently observed in the vicinity of exhaust pipes and petrol-fuelled vehicles.

Determination of Volatile Hydrocarbons in Urban Air
- 1992
-
Doctoral thesis (other academic/artistic)abstract
- In the complex hydrocarbon mixture in urban air, the alkenes and arenes are of particular interest with respect to impact on health and environment. Knowledge of hydrocarbon concentrations in urban air is essential for the assessment and prevention of health hazards and photochemical oxidant formation. Hydrocarbons in urban air were sampled on specially made triple-layer adsorbent cartridges. Easily carried equipment was used for the sampling. After thermal desorption, the hydrocarbons were analyzed by gas chromatography. An aluminium oxide column effected the separation of C2-C6 alkenes. Detection was generally by flame ionization but optional photoionization detection was found to be advantageous for the selective detection of alkenes and alkadienes in the C3-C5 region. A recently introduced technique based on differential optical absorption spectroscopy (DOAS) was compared with the gas chromatographic method for the determination of benzene and toluene in air. Proportions and exposure levels of hazardous hydrocarbons were determined in urban air. Ethene, propene, 1,3-butadiene and benzene made up approximately 5, 2, 0.5 and 6 per cent by weight of non-methane hydrocarbons. The composition was different for cold-start and high-speed emissions. Among the four isomeric butenes, the 2-butenes were prominent in petrol vapour and methylpropene in exhaust. The composition of pentenes was similar in petrol vapour and petrol exhaust. Concentrations of butadiene, reflecting outdoor urban exposure, were in the range of 0.5-5 mg/m3. The exposure of commuters to 22 volatile aromatic hydrocarbons of petrol exhaust was 5-10 times higher in cars than in trains. Generally, urban roadside concentrations of hydrocarbons decreased more than 10-fold with increased distance from motor traffic.

Exposure of commuters to volatile aromatic hydrocarbons from petrol exhaust
- 1991
-
In: The science of the total environment. ; 108, s. 225-233
-
Journal article (peer-reviewed)abstract
- Twenty-two volatile aromatic hydrocarbons were determined in the air of an automobile during commuting. Sampling was made on Tenax cartridges and laboratory determinations were carried out using thermal desorption combined with temperature-programmed capillary gas chromatography. Selected hydrocarbons representative of petrol exhaust were determined in the automobile and in an electric commuter train during eight parallel commuter trips. In the automobile, the concentrations of benzene were 35-70 micrograms/m3 and those of total aromatic hydrocarbons 200-400 micrograms/m3. The petrol exhaust levels were 5-10 times higher in the automobile than in the compartment of the commuter train.

Photoionization assessment of C3-C5 alkadienes and alkenes in urban air
- 1992
-
In: Journal of Chromatography. ; 591, s. 358-361
-
Journal article (peer-reviewed)abstract
- Hydrocarbons from samples of traffic-polluted urban air were separated by gas chromatography on an aluminium oxide column and assessed simultaneously by photoionization detection (PID) and flame ionization detection (FID) after effluent splitting. The 10.2 eV photoionization detector selectively detects alkadienes and alkenes but not alkanes and alkynes in the C3-C5 region. The maximum PID/FID response ratio for alkadienes and alkenes is also obtained in this region. The analytical system as a whole is particularly favourable for the C3-C5 alkenes. Analytical data are given for propadiene, 1,3-butadiene, propene, butenes and pentenes.

In: Chemosphere. ; 24, s. 135-140
-
Journal article (peer-reviewed)abstract
- Hydrocarbons of particular toxicological interest were determined in Scandinavian urban air as their fraction of total hydrocarbons except methane. Samples were taken on triple-layer adsorbent cartridges and the C2-C8 hydrocarbons were analyzed by gas chromatography on an Al2O3/KCl column. The approximate ratios 10:4:1 were observed for ethene, propene and butadiene. The proportion of these combustion-derived alkenes was low for cold starts, and highest for fast traffic.

Selective assessment of C2-C6 alkenes in air by adsorption sampling and gas chromatography
- 1991
-
In: Journal of environmental analytical chemistry. ; 45, s. 39-44
-
Journal article (peer-reviewed)abstract
- A system is described for the specific determination in air of ethene, propene, the four isomeric butenes, cyclopentene and the six isomeric pentenes. The butenes, pentenes and hexenes are well separated from the commonly occurring matrix of alkanes in much higher concentrations. Field samples were taken using easily carried equipment consisting of an air pump connected to an adsorbent cartridge. An advantageous combination of triple-layer adsorbents was found to be Tenax + Carbotrap + Carbosieve S-III. In the laboratory, the hydrocarbons were thermally desorbed into a cold trap. The trap was directly linked to the aluminium oxide PLOT column which effected the alkene separations.

Journal article (peer-reviewed)abstract
- Purpose Almost everything consumers buy in a store has a package. At point of purchase, the first moment of truth, the package functions as a silentsalesman. Once the purchase is made, the product is consumed in the second moment of truth. The purpose of this paper is to create a betterunderstanding of how customers evaluate different aspects of the package in the first and second moments of truth.Design/methodology/approach An empirical investigation is conducted on how customers experience three different packages for everydaycommodities in the first and second moments of truth. Causal modeling is used to analyze the impact of different benefits of a package onto customersatisfaction and loyalty.Findings It was found that both benefits and attributes can have different roles in affecting customer satisfaction and loyalty in different parts of theconsumption cycle. Furthermore, the results show that there are significant differences for the impacts of customer satisfaction on loyalty in the firstmoment of truth compared to the second moment of truth.Practical implications By applying a consumption system approach, it is possible for managers to design a package that can attract customers inthe first moment of truth and at the same time create customer satisfaction in the second moment of truth.Originality/value The research shows that the role of certain benefits and attributes can be different in the purchase and use situation. Previously,this has been modeled separately but by operationalizing the first and second moment of truth in the same model the true effects of various benefitsand attributes can be identified

Theory of Attractive Quality and Life Cycles of Quality Attributes
- 2011
-
In: The TQM Journal. - Bingley, UK : Emerald Group Publishing Limited. - 1754-2731 .- 1754-274X. ; 23:2, s. 235-246
-
Journal article (peer-reviewed)abstract
- Purpose – The purpose of this study is to shed further light on the dynamics of quality attributes, as suggested by the theory of attractive quality. The study aims to investigate the existence of the life cycle for successful quality attributes and to identify alternative life cycles of quality attributes.Design/methodology/approach – The research is based on two surveys in which a total of 1,456 customers (708 in 2003 and 748 in 2009) participated in the classification of quality attributes. In particular, the study investigated how customers perceived 24 particular packaging attributes at two points in time, in 2003 and 2009.Findings – The study identified three life cycles of quality attributes: successful quality attributes, flavor-of-the-month quality attributes, and stable quality attributes. The research also extends the theory of attractive quality by identifying the reverse movement of certain quality attributes; that is, that a quality attribute can take a step backwards in the life cycle of successful quality attributes through, for instance, a change in design.Originality/value – The paper provides empirical evidence for the existence of several alternative life cycles of quality attributes. The results of the empirical investigation increase the validity of the theory of attractive quality, which is important, given the limited amount of research that has attempted to validate the fundamentals of the theory of attractive quality.

Idea Generation : Customer Co-creation versus Traditional Market Research Techniques
- 2011
-
In: Journal of Service Management. - : Emerald Group Publishing Limited. - 1757-5818 .- 1757-5826. ; 22:2, s. 140-159
-
Journal article (peer-reviewed)abstract
- The purpose of this paper is to understand the differences between proactive and reactive market research techniques during the development of new market offerings. The study focused on the financial and innovative performance of traditional market research techniques, such as focus groups and in‐depth interviews, in comparison to more co‐creation‐oriented techniques that are designed to capture customers' value‐in‐use.Design/methodology/approachThe study was a two‐stage process. Study I, an empirical investigation of 195 development projects in European companies, examined how these companies use different market research techniques and how this relates to the profit margins of new products and services. Study II designed an experiment with 50 users of a consumer good and evaluated the contribution of different market research techniques, based on the degree of originality and customer value.FindingsSignificant differences were found, in terms of both content and originality, between the technique based on customer co‐creation and the two traditional market research techniques (Study II). These findings can help to explain why the relationship between the use of market research techniques and profit margin (Study I) is stronger for co‐creation techniques than it is for traditional market research techniques.Originality/valueDespite empirical evidence that the application of market research techniques based on co‐creation can lead to original ideas, there is a lack of valid studies regarding how co‐creation techniques perform in relation to more traditional methods of collaboration with customers.

Consumer Perception at Point of Purchase : Evaluating Proposed Package Designs in an Eye-tracking Lab
- 2010
-
In: Journal of Business & Retail Management Research. - : Journal of Business & Retail Management Research. - 1751-8202 .- 2056-6271. ; 5:1, s. 41-50
-
Journal article (peer-reviewed)abstract
- In today’s retail environment, consumer products are increasingly competing for customers’ attention. Research has shown that 60–80% of purchasing decisions are influenced in-store. Thus, packaging that stands out from competitors gains a competitive advantage. This study investigates the use of eye-tracking as a method to evaluate and design packaging with better Point-of-Purchase qualities. An eye-tracking laboratory was used and shoppers were recruited for three rounds of experiments. In total, 128 participants were recruited in order to assess the potential of eye-tracking. Results show that, when taking some methodological constraints into account, eye-tracking complements traditional methodologies with further insights when investigating the Point-of-Purchase qualities of packaging.
