Spoort de OV-studentenkaart met de wensen in de markt?

Hoeveel en welke studenten zijn voorstander respectievelijk tegenstander van de OV-studentenkaart en waarom? Dit waren enkele van de vragen die, voorafgaand aan de invoering van de verplichte OV-kaart (januari 1991), zijn onderzocht in voorjaar 1989 bij een steekproef van 931 studerenden aan het MBO, HBO en WO. Als theoretisch kader bij de analyse van deze vragen is gebruik gemaakt van het onderscheid dat Abell maakt in klantengroepen, klantenfuncties en alternatieve techno1ogieën en van het Fishbein en Ajzen attitudemodel. Het bleek destijds dat de helft van de studerenden de kaart een onaantrekkelijk nieuw produkt vond. Deze tegenstanders haddeneen reis- en vervoersgedrag waardoor zij zeer weinig openbaar vervoerskosten maakten. Dit kwam ofwel omdat men weinig reisde (men woont dicht bij ouders en studieplek), ofwel omdat men wel veel reisde maar dit met eigen vervoer deed (autobezitters en meerijders, motor- of bromfiets). Beide groepen zouden er door de invoering van de kaart, bij ongewijzigd reis- en vervoersgedrag, financieel op achteruit gaan vanwege de korting op de basisbeurs. Compensatie van de financië1e achteruitgang door bet substitueren van eigen vervoer door openbaarvervoer werd problematisch geacht omdat men de bereikbaarheid van de reisdoelen met openbaar vervoer als slecht beoordeelde. Vergeleken met de tegenstanders reisden de voorstanders reeds veel met openbaar vervoer zodat zij financieel (vrijwel) quitte zouden spelen of er op vooruit zouden gaan. Uit de intenties tot verandering in reisgedrag bleek dat er vooral een toename van het reisgedrag met het openbaar vervoer te verwachten was in de daluren (bezoeken aan familie, vrienden, recreatiedoelene.d.) en niet in de spits. Als belangrijkste conclusie van de resultaten kan genoemd worden dat wanneer een niet-verplichte OV-kaart geïntroduceerd zou zijn tegen een hogere prijs dan de huidige korting op de basisbeurs, dit beter zou hebben gespoord met de wensen in de markt dan de huidige verplichte OV-kaart

The Key to Successful Euromarketing: Standardization or Customization?

Using a framework that incorporates notions from economics and consumer behavior, this paper examines the similarities and differences with respect to consumers and marketing infrastructure in the countries of the European Union. The conclusion is that there are tremendous differences in income levels and income spending patterns among the countries of the European Union and also major differences with respect to consumer values and lifestyles. Furthermore, the distribution and retailing environments as well as the media, differ considerably from one country to the other. The perspective of completely standardized marketing strategies for the whole European Union is still far removed. If a consumer homogenization process is taking place at all, such a process is likely to be slow. Suppliers (i.e., manufacturers and retailers) adopting Euro-oriented marketing strategies will contribute more to the emergence of the `European Consumer' than the autonomous cultural homogenization process

Storage versus substrate limitation to bole respiratory potential in two coniferous tree species of contrasting sapwood width

Abstract Two coniferous tree species of contrasting sapwood width (Pinus ponderosa L., ponderosa pine and Pseudotsuga menziesii Mirb., Douglas-fir) were compared to determine whether bole respiratory potential was correlated with available storage space in ray parenchyma cells and/or respiratory substrate concentration of tissues (total nitrogen content, N; and total non-structural carbohydrate content, TNC). An increment corebased, laboratory method under controlled temperature was used to measure tissue-level respiration (termed respiratory potential) from multiple positions in mature boles (>100-years-old). The most significant tissue-level differences that occurred were that N and TNC were two to six times higher for inner bark than sapwood, TNC was about two times higher in ponderosa pine than Douglas-fir and there was significant seasonal variation in TNC. Ray cell abundance was not correlated with sapwood respiratory potential, whereas N and TNC often were, implying that respiratory potential tended to be more limited by substrate than storage space. When scaled from cores to whole boles (excluding branches), potential net CO 2 efflux correlated positively with live bole volume (inner bark plus sapwood), live bole ray volume, N mass, and TNC mass (adjusted R 2 > >0.4). This relationship did not differ between species for N mass, but did for live bole volume, live bole ray volume, and TNC mass. Therefore, N mass appeared to be a good predictor of bole respiratory potential. The differences in net CO 2 efflux between the species were largely explained by the species' relative amounts of whole-bole storage space or substrate mass. For example, ponderosa pine's inner bark was thinner than Douglas-fir's, which had the greater concentration of ray cells and TNC compared with the sapwood. This resulted in ponderosa pine boles having 30-60% less ray volume and 10-30% less TNC mass, and caused ponderosa pine net CO 2 efflux/ray volume and net CO 2 efflux/ TNC mass to be 20-50% higher than Douglas-fir. In addition, because inner bark respiratory potential was 2-25 times higher than that of sapwood, ponderosa pine's thinner inner bark and deeper sapwood (relative to Douglas-fir) caused its bole net CO 2 efflux/live bole volume to be 20-25% lower than that of similarlysized Douglas-fir trees

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

• A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration rates radially and vertically within stems. • Respiration of inner bark was 2–3 times greater than sapwood, and 50–70% higher in outer than inner sapwood. Inner bark and outer sapwood released > 40% more CO2 at treetops than at bases. Trends were robust for CO2 production on a core dry‐mass, volume, or total carbon basis. By contrast, CO2 production on a nitrogen basis showed almost no significant variation. • This in vitro technique provided an effective index for relative differences in respiration within tree stems. Discrepancies between in vitro and in vivo measurements might be related to the gaseous environment in stems. The estimated within‐stem gradients in respiration were possibly determined by enzyme quantity and availability and could be useful in scaling to whole‐trees

A randomised controlled trial of nurse-managed trial conclusion following early phase cancer trial participation

The effect of a nurse-managed intervention, for early phase cancer trial participants at trial conclusion, on psychosocial outcomes was evaluated at two cancer centres in the Midlands, England using a randomised controlled trial. It involved 117 patients who were participating in an early phase cancer clinical trial. It was a nurse-managed trial exit, which included a trial exit interview, trial feedback information leaflet and telephone follow-up compared with standard care at trial conclusion. Psychological distress at 1 week and 4–6 weeks post-trial conclusion, patient's knowledge and understanding and patient's satisfaction were assessed. The results showed there was no significant difference between the two groups regarding scores for anxiety and depression at time one and time two. There is some suggestion that the intervention reduced anxiety from trial conclusion to follow-up (P=0.27). Patients in both groups felt they had contributed to cancer research through trial participation. However, intervention patients were more likely to feel that they knew how the trial was going (P<0.001), knew how other people in the trial were doing (P=0.001), had all the feedback they needed about the trial they took part in (P<0.01) and knew how they would be followed up (P=0.02). Patient satisfaction with the intervention was high (median score=4.5 where 5 is greatest satisfaction). In conclusion, nurse-managed trial conclusion led to positive outcomes for patients who had recently completed a clinical trial
