An Investigation of the Factors Affecting Innovation Performance in Chain and Independent Hotels

SUMMARY

The failure rate of new service projects is high, because the knowledge about how innovations should be developed is limited. In the last decade, several studies have investigated the success factors associated with service innovations (e.g., Atuahene-Gima, 1996; de Brentani, 2001; Storey and Easingwood, 1998). However, no research in new service development (NSD) has addressed the question of whether chain affiliated and independently operated service firms have different approaches for developing successful innovations. The majority of past new service development (NSD) success studies have concentrated on the financial service sector, which is generally represented by large corporate organizations. The findings of this study indicate that the factors which impact on the performance of NSD depend on the organizational relationship of hotels-chain affiliation or independent operation. The study's results suggest that market attractiveness, process management, market responsiveness and empowerment predict NSD success within chain affiliated hotels. While empowerment and market attractiveness are also related to NSD success in independent hotels, this is also linked to effective marketing communication, employee commitment, behaviour based evaluation, training of employees and marketing synergy.

Does organizational creativity always drive market performance?

This study develops and tests arguments that the relationship between organizational creativity and market performance is channeled through new product development (NPD) capability, and that the indirect effect of creativity on performance, via NPD capability, is conditional upon levels of environment dynamism and market responsiveness. The proposed relationships are tested on a sample of 221 small‐ and medium‐sized enterprises (SMEs) in a major sub‐Saharan African market. Findings from the study indicate that process and product NPD capabilities partially mediate the effect of novelty and usefulness elements of organizational creativity on market performance. The study further finds that while environment dynamism weakens the indirect effects of novelty and usefulness of organizational creativity, via process and product NPD capabilities, on market performance, the effects are strengthened under conditions of greater responsiveness to target market needs. A theoretical contribution from this study is the finding that how organizational creativity dimensions drive market performance is more complex than previously thought: it depends on whether or not organizational creativity components are first used to develop an organization's process and product innovation capabilities, and whether target market environment conditions are dynamic and an organization has ability to respond to target market demands.     

A knowledge sharing framework for black,grey and white box supplier configurations in new product development

Managing supplier collaboration is increasingly cited as a key success factor in new product development (NPD) performance. Knowledge sharing between customer and supplier is a critical issue to manage collaboration but one which has only been partially investigated in the inter-organisational NPD context. This means that the specific characteristics of knowledge sharing according to the three classical supplier involvement configurations (black box: design is supplier driver, grey box: joint design and white box: design is customer driven) are still largely unknown. This research proposes to fill this gap by presenting a conceptual framework for knowledge sharing according to the supplier involvement configuration. Knowledge sharing integrates knowledge transfer, translation and transformation. A qualitative methodology based on cross-case comparisons of six projects in two companies is used. This research shows that the dynamics of knowledge sharing depend on each configuration. Thus, for black box projects, knowledge translation is a prerequisite for knowledge transfer. For grey box projects, knowledge transfer and translation are initiated simultaneously in a continuous loop. For white box projects, knowledge transfer is the key activity and potentially generates knowledge translation. The results suggest that managers should pay attention to translation activities which are critical for the success of co-development projects.

地震荷载下反倾层状岩质边坡倾倒变形破坏规律及数值模拟研究

为了掌握不同地震荷载作用下的边坡稳定性能,采用振动台试验并结合离散元数值模拟对典型反倾层状岩质边坡进行了分析,对地震作用下反倾层状岩质边坡的动力响应特性和变形破坏规律进行了研究。结果表明：1)边坡的顶部和坡面首先出现变形,边坡开始出现层间错动导致最终彻底破坏;2)地震波频率对边坡的变形破坏有着显著影响,不同频率正弦波作用于边坡时,边坡上各个地方的加速度响应状况各不相同;3)在频率较小的正弦波作用下边坡的顶部及坡面浅表部松动变形,在频率较大的正弦波作用下边坡内部出现横向拉张裂缝,拉张裂缝会导致边坡的崩塌溃坏;4)在数值模拟分析边坡的加速度响应情况时,从边坡底部到顶部,随着高程的不断增加,其加速度放大系数增长幅度逐渐增加;5)地震波不仅影响边坡上监测点位加速度响应的大小,同时还对不同高程下其加速度响应变化情况产生影响。研究结果显示了边坡加速度响应数值模拟分析与振动台模型试验结果的一致性,所得结论对工程施工参数设计具有一定的借鉴价值。
