一种OFDM系统中频率同步的改进算法

针对传统的频率同步方法中估计精度与估计范围的矛盾,提出了一种改进的频率同步算法。该算法通过两次频率偏移估计,可以同时获得大的估计范围和高的估计精度,而且对训练序列没有其他限制,可以提高系统数据传输效率。通过仿真,验证了该算法的有效性。     

中国主要省区物质资本与人力资本利用效率及投资取向

要实现区域的可持续发展,提高资源利用效率是一个根本性的问题。而作为主要生产资源的物质资本与人力资本的利用效率就具有更重要的意义。文章以经济增长理论为依据,利用生产函数分析了中国主要省区物质资本与人力资本对经济增长的贡献率,发现1990年代之后大多数省区的人力资本贡献率已超过了物质资本的贡献率,说明经济增长方式已发生了由外延式向内涵式的很好转变。进一步根据生产者均衡理论,计算了主要省区物质资本与人力资本的利用效率,发现大部分省区的利用效率没有达到最优状态,但1990年代以来利用效率在不断提高。在此基础上,计算了通过提高两项资本利用效率可带来的GDP增长潜力,发现当利用效率达到最高时GDP可增长近24%。由此给出了各省区物质资本与人力资本投资比例的调整方向。

Mindfulness-based training interventions for employees: A qualitative review of the literature

We provide a comprehensive qualitative review of 67 published studies that have examined mindfulness-based training interventions conducted with employees. The findings indicate that the most common research designs were the pre-test/post-test only design (35.8%) and the randomized waitlist control group design (26.9%). About two-thirds of the studies included a control group (61.2%), with approximately three-quarters (75.6%) of these studies using random assignment. Of the 63 studies that used a conventional experimental design, the majority (65.1%) included only one follow-up assessment, most often immediately after training. Results indicated a great degree of heterogeneity in terms of program content, although many studies used some adaptation of Kabat-Zinn's (1990) Mindfulness-Based Stress Reduction (41.8%), an approach with a strong evidentiary base with clinical populations. All training programs incorporated practice, most (85.1%) used multiple methods of delivering the training material, and training varied considerably in total duration, session length, and the number of training sessions. Our review also found that the intended purpose of mindfulness-based training for employees was most commonly the reduction of stress/strain (80.6%), although a wide range of other targeted outcomes were documented. Based on our findings, we offer suggestions for future research aimed at advancing our understanding of mindfulness-based training interventions with employees.

Consumer response to service brand physical elements: Using a semantic priming task to explore implicit understanding of service brand meaning

Consumers' responses to design features involve both conscious and non-conscious information processing. The current research therefore argues that a combination of explicit and implicit measures should be used to assess consumer understanding of service brand meaning conveyed by a service brand's physical elements. However, most methods traditionally used to evaluate design meaning are explicit methods, based on conscious cognitive processes. The current research addresses this gap by documenting how understanding of service brand meaning conveyed by a service brand's physical elements can be tapped by an implicit measure. More specifically, it aims to investigate the extent to which a greater ability to decode meaning conveyed by design features results in differences in implicit understanding of service brand meaning. This research uses a Semantic Priming Task to assess associative strength between brand meaning and a service brand's physical elements. Results (N = 157) show that command of the design language, captured by design acumen and involvement in the product category, results in greater ability to implicitly understand brand meaning conveyed by a service brand's physical elements, and moderates the implicit-explicit relationship. Results suggest that combining implicit and explicit measures may help practitioners in charge of creating brand's physical elements, especially when associations between design types and brand impressions are not constant across product categories.     

Will AI ever sit at the C-suite table? The future of senior leadership

As the sophistication of artificial intelligence (AI) systems develop and AI becomes a key element of organizational strategy across a wide spectrum of industries, new demands are being placed on senior leaders. To understand the growing challenges leaders will face in the age of AI, we conducted interviews with 33 senior leaders in several countries across a wide range of industries. Our research highlights key capabilities and skills that leaders will require. Underlying these capabilities is a mindset oriented toward continuous learning and self-development, which will enable ongoing and rapid adaptation to change. Our findings identified the following key capabilities: digital know-how, data-driven focus, networking, ethics, and agility. To successfully navigate the coming era, senior leaders will need to focus on reskilling the workforce, recruiting and retaining highly skilled talent, building an intrapreneurial culture, and managing unprecedented changes in technologies and the nature of work.
