The dynamics of technological change in UK retail banking services: An evolutionary perspective 总被引：1，自引：0，他引：1
Davide Consoli 《Research Policy》2005,34(4):461-480
The purpose of this paper is to elaborate an evolutionary perspective on the process of structural change that has characterized the banking industry in the United Kingdom (UK). For this purpose, the evolution of retail financial services is contrasted against the backdrop of the implementation and development of information and communication technologies (ICTs). The paper delves into the sources and the effects of technological change in banking over a long-term perspective (1840s-1990s) to point out the significance of the opportunities and the constraints that have shaped the growth and development of this industry. This is interpreted as a three-stage evolutionary process driven by intertemporal coordination across several complementary domains, including activities of production, business organization, consumption and the underlying regulatory setting. It is concluded that the evolution of UK retail banking displays the characteristics of a distributed process of innovation in which developers of technologies, service suppliers and customers contribute to the process of structural change of the industry. 相似文献

In a contemporary clinical laboratory it is very common to have to assess the agreement between two quantitative methods of measurement. The correct statistical approach to assess this degree of agreement is not obvious. Correlation and regression studies are frequently proposed. However, correlation studies the relationship between one variable and another, not the differences, and it is not recommended as a method for assessing the comparability between methods.
In 1983 Altman and Bland (B&A) proposed an alternative analysis, based on the quantification of the agreement between two quantitative measurements by studying the mean difference and constructing limits of agreement.
The B&A plot analysis is a simple way to evaluate a bias between the mean differences, and to estimate an agreement interval, within which 95% of the differences of the second method, compared to the first one, fall. Data can be analyzed both as unit differences plot and as percentage differences plot.
The B&A plot method only defines the intervals of agreements, it does not say whether those limits are acceptable or not. Acceptable limits must be defined a priori, based on clinical necessity, biological considerations or other goals.
The aim of this article is to provide guidance on the use and interpretation of Bland Altman analysis in method comparison studies.Key words: Bland-Altman, agreement analysis, laboratory research, method comparison, correlation of data 相似文献

An extended model based on the theory of planned behaviour (TPB) was used to study Chinese English as a foreign language (EFL) students’ in-class participation. The model included the core TPB constructs (behavioural intentions, attitudes, subjective norms, and perceived behavioural control/self-efficacy) and 2 additional constructs (foreign language classroom anxiety and face-saving) frequently discussed in the literature about Chinese EFL classroom dynamics. A total of 199 Chinese students enrolled in a Sino-American international branch campus were surveyed. The results of a partial least squares (PLS) path modelling analysis revealed that attitudes, subjective norms, perceived behavioural control/self-efficacy, and face-saving explained 46% of the variance in intentions to participate in English in class. Perceived behavioural control/self-efficacy fully mediated the negative indirect effect of foreign language classroom anxiety on intentions. Pedagogical implications and future directions are discussed for implementation purposes. 相似文献

ABSTRACT This paper reports on findings from an exploratory investigation about parents’ perceived role of the Facebook Like in sharenting (i.e., sharing about their children on social media) by drawing on the qualitative results of an online survey. Findings show that the majority of participants think that getting a Like on a picture of one’s child can encourage a parent to share more about him/her because of two main understandings of this paralinguistic cue: the Like as a received validation of one’s parenting, or as a metric of connection with important people, causing emotional reactions in the receivers. Several parents, though, judge the Like as more commonly being important for others, explaining this difference in terms of internal characteristics. This study aims to extend our understanding of the motivations behind sharenting by taking into account the role of the Like in this practice and highlighting how parents position themselves in such an exchange of digital photo-sharing and feedback. As communication does not happen in a vacuum, we advance that research on parents’ photo-sharing behavior online may benefit from considering whether and how social media liking can foster and shape interpersonal communication between posters and recipients. 相似文献

This paper aims to figure out the potential impact of Big Data (BD) on Critical Success Factors (CSFs) of Customer Relationship Management (CRM). In fact, while some authors have posited a relationship between BD and CRM, literature lacks works that go into the heart of the matter.Through an extensive up-to-date in-depth literature review about CRM, twenty (20) CSFs were singled out from 104 selected papers, and organized within an ad-hoc classification framework. The consistency of the classification was checked by means of a content analysis. Evidences were discussed and linked to the BD literature, and five propositions about how BD could affect CRM CSFs were formalized.Our results suggest that BD-enabled CRM initiatives could require several changes in the pertinent CSFs. In order to get rid of the hype effect surrounding BD, we suggest to adopt an explorative approach towards them by defining a mandatory business direction through sound business cases and pilot tests. From a general standpoint, BD could be framed as an enabling factor of well-known projects, like CRM initiatives, in order to reap the benefits from the new technologies by addressing the efforts through already acknowledged management paths. 相似文献

Knowledge Intensive Business Services (KIBS) are intermediary firms which specialise in knowledge screening, assessment and evaluation, and trade professional consultancy services. The remarkable rise of this broad class of activities is perceived by many as the natural by-product of modern knowledge economies within which increasing specialisation induces the need for professional agents in the markets for external knowledge. This paper addresses critically a conceptual flaw in the specialised literature which portrays KIBS as a homogeneous group of activities. Using official data on occupational information in the United States we observe and analyse high variety across KIBS sectors’ occupational structures and skill requirements. 相似文献

In an informal study, two versions of a story involving probability are introduced to undergraduates. The findings reveal that students have troubles detecting equal probabilities in a sampling scheme without replacement in which no information on earlier draws is available. 相似文献

This study investigated two different expressions of the so-called curse of knowledge in primary school children: hindsight bias and outcome bias. Further, it explored the possible predictive function of false belief understanding in reducing these biases. Ninety-one children aged 7, 9, and 11 years (middle- to upper-middle class) were administered classical first- and second-order false belief tasks as well as hindsight and outcome bias tasks in a within-subjects design, while controlling for cognitive level. Both biases were found at all ages. Second-order false belief understanding seemed to reduce outcome bias but not hindsight bias. These findings indicate that the curse of knowledge is a multifaceted construct with potential relevant implications for learning in children. 相似文献

Ultrasonography(US) and the new applications US elastography(USE) and contrast-enhanced US(CEUS) are used in the screening of thyroid nodules,for which fine-needle aspiration biopsy(FNAB) is the best single diagnostic test.The aim of the study was to compare the sensitivity,specificity,positive predictive value(PPV),and accuracy of the four examinations in nodules with cytological and histological diagnoses.The study used data from US,FNAB,USE(elasticity(ELX 2/1) index),and CEUS(Peak index and time to peak(TTP) index) evaluated in 73 thyroid nodules in 63 consecutive patients likely to undergo surgery.Cytological-histological correlation was available for 38 nodules.No correlation emerged between nodule size and cytological results.A significant(P=0.03) positive correlation between cumulative US findings and cytological results was found.In addition,significant correlations between cumulative US findings and cytology(P=0.02) and between cumulative US findings and histology(P<0.0001) were found.US showed the best specificity and PPV,and FNAB the best sensitivity.There was no significant difference in the ELX 2/1 index,Peak index,or TTP index among nodules subdivided according to cytological scores.No significant correlation was found between ELX 2/1 index,Peak index,and TTP index,on the one hand,and nodule size,US cumulative findings,cytology,and histology on the other hand.The sensitivity of the ELX 2/1 index was high,but its specificity was very low.The accuracy and PPV of USE were lower than those of the other procedures.Only the correlation between Peak index and cumulative US findings reached a value close to significance.Our ultimate aim is to minimise unnecessary thyroidectomy.US and FNAB continue to play a central diagnostic role.The use of a US score showed high specificity and PPV.The specificity of FNAB was low in this selected series because of the numbers of indeterminate cytological responses.USE and CEUS are innovative techniques that need to be standardized.The ELX 2/1 index,Peak index,and TTP index seem to be unrelated to histology.The best statistical data on USE and CEUS concerned their sensitivity and PPV,respectively.At present,USE and CEUS are too time-consuming and of limited utility in selecting patients for surgery. 相似文献
