基于椭圆球面波函数的数字带通滤波器设计

为设计频谱性能优良的有限冲激响应(FIR)数字带通滤波器,从窗函数的性质及选择指标出发,分析了椭圆球面波函数(PSWF)作为窗函数的优势;在此基础上根据数字滤波器设计的原理和要求,选择0阶基带椭圆球面波函数作为窗函数设计数字带通滤波器,并利用微分方程状态转移矩阵逼近的PSWF求解算法,给出了基于PSWF的FIR数字带通滤波器设计方法。理论分析和仿真结果表明：PSWF数字带通滤波器具有较低的设计复杂度,与Kaiser滤波器和Blackman滤波器相比,其旁瓣衰减有超过7 dB的优势,且具有与两种滤波器相当的通带波纹波动和过渡带宽。     

Knowledge of campaign finance regulation reduces perceptions of corruption

We use an experimental survey design to measure how campaign finance regulation influences perceptions of political corruption and trust in politicians when citizens are exposed to information about regulation. Unlike most observational studies, results of this experimental study suggest that knowledge of campaign finance regulation substantially reduces citizens’ perceptions of corruption but has only limited effect on trust in politicians. Findings have crucial implications for public policy. At a time when public cynicism about politics is high, a significant reduction in perceptions of political corruption through successful dissemination of campaign finance regulation would be a boost to the legitimacy of democracies.

Personality and older consumers’ green behaviour in the UK

The UK government has set an ambitious target of reducing greenhouse gas emissions by 80% before 2050. An interesting segment that could help to achieve this is older consumers, due to their growing numbers. There seems to be a lack of attention, in the research looking specifically at different age categories of older consumers’ green behaviour, and whether their level of greenness can be explained by their personality. Using Socioemotional Selectivity Theory and Time Perspective, the research presented here was designed to provide an exploratory analysis of how the green behaviour of older consumers is explained by their personality types. Based on the responses of 204 older consumers in the UK, our results find the openness personality trait to be positively linked to green behaviour, whilst the extraversion personality trait is negatively related to green behaviour. Although the level of green behaviour increased with older consumers’ age, this did not reach significance.     

Barriers to the investment in the Concentrated Solar Power sector in Morocco: A foresight approach using the Cross Impact Analysis for a large number of events

The Scenario Analysis methods have often been used by policy makers as an instrument to manage uncertainty and to support the shaping of long-term economy policies. In this research, we apply Scenario Analysis in order to identify the barriers affecting the decision to invest in the Concentrated Solar Power (CSP) sector in Morocco. Our results aim at facilitating the process of defining different paths in strategic political and policy actions. Using data from a survey on a panel of experts, the Cross Impact Analysis (CIA) and the Cross Impact Matrix System (SMIC) techniques are applied. The advantage of these techniques is that they allow including in the analysis the interlinkages between the events that will define the future scenarios. However, their limitation is that the number of events analyzed cannot be too high since the information collected from the experts increases exponentially according to the number of events introduced. We thus expand our analysis with a new methodological approach, combining the use of prospective and statistics techniques. This approach allows addressing the mentioned limitation and applying these techniques, initially restricted to 6 events in its common application, to a large number of events. The results show that uncertainty and informality would be key factors in promoting the arrival of companies in this sector. Additionally, regarding companies that already have a presence in Morocco’s renewable energy sector, an increase in activity would be achieved through improvements in the easing of financial and legal barriers.     

Scenarios and design: Scoping the dialogue space

This paper examines the intersections between two futures-oriented domains of practice and research: scenario planning and design. Both are practice-led, with uneasy but productive relationships with theorizing. Exploring their relations offers ways to address challenges faced by interdisciplinary management research, which struggles to connect research and practice. The authors describe how they brought the two fields together. We outline how we convened, designed and facilitated the fourth Oxford Futures Forum held in May 2014. This event brought together leading practitioners and researchers in a collective inquiry based on self-organizing, generative and reflexive making and dialogue. How participants engaged, from responding to the invitation to take part, as well as their practical and discursive encounters with one another during the event, threw up similarities and differences between the two fields. We present nine themes that capture the links and spaces between design and scenarios, yet suggest that they are not a straightforward overlap or a simple relationship, but rather a range of interactions between the fields, including feeding in, bridging, tension and repulsion. The paper's contribution is to suggest how scenario planning can engage with design, resulting in new opportunities for research and projects. These modes of engagement provide a framing to explore dialogues between other management disciplines.     

环境意识与企业形象塑造

可持续发展的思想和社会市场营销观念已成潮流。为适应市场需求的变化和环境管理的要求,寻 求市场机会和避免环境威胁,必然要求企业树立环境意识,履行应尽的社会责任,并融入、体现在企业 形象塑造中。在企业识别系统中贯穿“环境形象”设计是企业形象塑造的关键。     

虚拟企业与耗散结构理论

作为系统论的新发展,耗散结构理论主要研究一个系统从无序向有序,从低序向高序转化的机理、条件和规律。将耗散结构理论的思想和方法用于解决管理领域的问题,需要满足耗散结构的一般性判据。虚拟企业是多个企业自发形成的一种自组织结构,具有耗散结构的特征。虚拟企业系统中的耗散结构特征表现在开放性、远离平衡态和序参量的存在。
