Small firm networks: a successful approach to innovation?   总被引:3,自引:0,他引:3  
This paper considers the increasing trend of inter–working among small firms. Networks of small firms co–operate in certain activities, such as marketing, purchasing, R&D, training or manufacturing. But does co–operation lead to innovation? To answer this question published evaluations of small firms co–operating for mutual benefit are reappraised. Inter–working among small firms is then investigated further by interviewing three network brokers. The brokers were funded by regional governments and they facilitated co–operation between small firms. These semi–structured discussions explored the key characteristics of successful networks, the responsibilities of the broker and the level of innovation occurring. Networking is primarily a competitive response. It needs to evolve into a mechanism to enable small firms to develop innovative products and processes jointly. Small firms may have to rethink their approach to co–operation, and their motives for initiating inter–working if they are to benefit fully from co–operation.  相似文献

In this study, we investigate the impact of IFRS adoption in Europe and Australia on the relevance of book value and earnings for equity valuation. Using a sample of 3488 firms that initially adopted International Financial Reporting Standards (IFRS) in 2005, we are able to compare the figures originally reported for the 2004 fiscal years to the IFRS figures that were provided in 2005 as the 2004 IFRS comparative figures. As part of the inquiry, we introduce a cross-product term, equal to the product of EPS and BVPS, into the traditional linear pricing models. The estimated coefficient on the cross-product term is statistically significant and negative, as theory suggests in the presence of important nonlinearities. Further, there is increased non-linearity in the data subsequent to IFRS adoption, with the increase being most pronounced for firms in Common Law countries. With non-linear effects controlled for, there is no observed change in price relevance for firms in either Code Law or Common Law countries, contradicting the results from the linear pricing models. The results also suggest that the distribution of measurement errors becomes more similar across Code Law and Common Law countries after the adoption of IFRS, removing one difference between these groups. Thus, IFRS enhances comparability, an inference that would not be possible had we confined the analysis only to linear pricing models.  相似文献

Product pictures with “headless” decorative models, whose heads have been cropped out of the pictures, are often used in online retailing. This article reports findings from three experiments comparing attitudes for clothing displayed in pictures with cropped and uncropped male and female models, focusing on the moderating effects of consumer and model gender and the mediating effects of product self‐referencing. Results indicate that the effects on product attitudes are moderated by the gender of both models and consumers and mediated by self‐referencing. Pictures with uncropped male models result in more positive product attitudes, irrespective of consumer gender. For product pictures with female models, male consumer attitudes are also more positive for products displayed with uncropped models. In fact, attitudes are only more positive for clothing shown with cropped, “headless” models when both models and consumers are female. Implications of the findings for research and practitioners are discussed.  相似文献

An increased focus on international and national levels of society to meet the transportation needs of older people and people with disabilities is realized through legislation, directives and guidelines on accessibility. This paper examines effects of removing physical barriers according to current Swedish governmental accessibility directives on older peoples’ perceptions of outdoor environments (usability) and on their mobility and perceived safety as pedestrians. This paper also focuses on municipal planners’ views on the implementation of improved accessibility. A before–after study, using both qualitative and quantitative methods, is conducted. The results from the questionnaires show that older peoples’ overall satisfaction with the outdoor environment has increased after implementation; however no differences are found if physical barriers specifically are considered. Older peoples’ mobility is also unchanged; nevertheless, fewer respondents are stating difficulties in walking due to barriers in the outdoor environments as reason to avoid outdoor mobility. Problems do remain after implementation, for example concerning safety/security-related issues and inaccessible entrances and indoor environments.  相似文献

This paper describes a diagnostic tool for assessing relative impact weights of time-dependent information on an impression or judgment and illustrates its use in the area of order effects. A novel and somewhat counterintuitive finding, based on applying this tool, is that the bit of information associated with the greatest impact weight is not necessarily the bit of information associated with the greatest relative impact weight. At the heart of this tool is the ability to compute precisely the relative impact weights associated with each piece of information, which are, in general, different from the actual impact weights associated with each piece of information. This provides the opportunity to determine relative impact weights under various assumptions about, and theories of, or related to, impression formation. In turn, this diagnostic information may be used to deepen understanding of a particular theory or, perhaps, to propose or define new theory.  相似文献

Objective: Apart from improved health outcomes, treatment convenience per se may have a value to individuals. This is sometimes referred to as process utility and can be estimated in terms of willingness-to-pay (WTP) or quality-adjusted life-years (QALYs). Previous research has produced multiple studies on QALY gains and WTP estimates of insulin-related attributes. There are, however, significant variations between studies, and it is not clear to what extent the value is a reflection of the true preferences or a consequence of the methodological approach. The aim of this study is to estimate the preferences for treatment attributes associated with basal insulin (administration frequency, administration flexibility, and treatment-induced weight gain) using both QALYs—elicited using time trade-off (TTO) and WTP—among a sample of the Swedish general population and among a sample of the Swedish diabetes population.

Methods: Data was collected using web-based surveys which were distributed to members of internet panels. The WTP survey presented five hypothetical scenarios with an offer to pay the incremental cost to receive basal insulin with improved attributes. The TTO survey presented six hypothetical scenarios where the respondent could choose between living for the rest of his/her life with diabetes and receiving treatment with a basal insulin with certain attributes or live for a shorter time with full health. The scenarios were combined with either a basal or a basal–bolus treatment regimen. Results from the TTO analysis were translated into monetary estimates using a threshold value of SEK500,000 per QALY.

Results: In total, 2012 responses were included. The ratings of the attributes were almost identical, irrespective of method for the general population, while it differed to some extent for the diabetes population. The methods produced the same value for flexibility, but the estimates generated with the TTO approach were higher for one less injection and avoided weight gain. The general population assigned a higher utility gain to convenience attributes, while the diabetes population assigned a higher utility gain to avoiding weight gain.

Limitations: About a quarter of the respondents did not accept the scenario in the WTP survey, i.e. protesters.

Conclusions: The ranking of the attributes was generally independent of evaluation method, but the TTO method resulted in similar or higher values compared to the WTP method.  相似文献

This paper investigates how the organizational life-cycle stage of the firm and the existence of venture capital investors affect the use of management control systems. The study consists of three types of management control systems, i.e. business planning, budgeting and management control techniques. Our empirical analyses are based on a survey questionnaire of 105 Finnish firms operating in all industries at different life-cycle stages. The results indicate that the business planning and use of management control techniques differ between the organizational life-cycle stage of the firm and the existence of venture capital investors. However, the existence of venture capital investors is also essential in maturity and revival firms while the earlier literature emphasizes their role in start-up and growth firms. Our results remain the same after conducting various robustness checks.  相似文献

This research introduces attitude towards the endorsement as a mediating variable in the relationships between celebrity source and endorsement factors and brand attitude. It also includes perceived celebrity motive, a variable rarely studied in the previous literature, as an endorsement factor. In a survey study, respondents evaluated four celebrity endorsement campaigns. Mediation analyses show that attitude towards the endorsement mediates the effects of three variables on brand attitude; these variables are celebrity expertise, celebrity–brand fit, and perceived celebrity motive. Moreover, results show that if consumers perceive that the celebrity was motivated to do the endorsement not only by money but also by product quality, this has a significant positive effect on attitude towards the brand.  相似文献

ABSTRACT

Though organizations increasingly collaborate with social media influencers, such as bloggers and videobloggers, little is known as to how the contextual cues related to sponsored content affect the authenticity perception of the social media influencers among audience members. This study explores how positive and negative priming of sponsored content shapes the authenticity perception of the vlogger among its audience members. Four different manipulation conditions were constructed to study a U.S. based travel vlog on Qualtrics, with data collected via Amazon’s Mechanical Turk. A theory-guided content analysis of 211 open viewer responses was conducted to compare perceptions of authenticity between the manipulation groups. The results verified the significance of priming: the same sponsored content can result in opposite reactions among the audience members depending on the positive/negative valence of the introductory text attached, highlighting the central importance of strategic communication related to the perception of sponsored content. The results also point out the importance of audience member engagement for experienced authenticity: The manipulation of audience participation with the vlog had a stronger effect on the perception of authenticity of the vlogger than the positive/negative valence of the introductory text.  相似文献

ABSTRACT

Sharing economy businesses require extensive trust-based communication between users and service providers to facilitate users’ positive persuasion processes. Based on Aristotle’s rhetorical theory, this study identifies three key persuasive cues (credibility, emotional bonding, and accommodation characteristics) and validates their roles in establishing users’ trust in an Airbnb setting. The moderating role of interactivity is further analyzed. Research findings from a survey sample of 171 Airbnb users indicate that persuasive cues are positively associated with trust in Airbnb hosts, which significantly leads to Airbnb brand trust. Interestingly, the moderating role of interactivity is only found in the relationship between emotional bonding and trust in Airbnb hosts. This study contributes to a better understanding of the factors that affect users’ trust building in the sharing economy context, and it offers guidance for platform providers to better operate their businesses by highlighting the important roles of persuasive cues and interactivity in users’ trust-building processes.  相似文献
