丁广义割圆序列的线性复杂度

Minimal polynomials and linear complexity of binary Ding generalized cyclotomic sequences of order 2 with the two-prime residue ring Zpq are obtained by Bai in 2005. In this paper, we obtain linear complexity and minimal polynomials of all Ding generalized cyclotomic sequences. Our result shows that linear complexity of these sequences takes on the values pq and pq-1 on our necessary and sufficient condition with probability 1/4 and the lower bound （pq - 1）/2 with probability 1/8. This shows that most of these sequences are good. We also obtained that linear complexity and minimal polynomials of these sequences are independent of their orders. This makes it no more difficult in choosing proper p and q.

管理层风险特质、董事会治理与科技保险参保意愿

本文综合行为金融、公司治理和公司金融理论构建科技保险参保意愿影响因素的理论模型,并基于浙江省635家高新技术企业的问卷调查数据进行实证检验。结论表明:第一,管理层风险偏好和管理层风险认知对高新技术企业科技保险参保意愿具有显著影响:风险喜好型管理者更倾向于采取风险自担策略,抑制科技保险需求;而较高的风险认知则有助于提升企业购买科技保险的意愿。第二,良好的董事会治理有助于提升企业风险管理,独立董事占比越高,企业购买科技保险的意愿越强。第三,管理层风险认知在董事会独立性与企业参保意愿之间发挥部分中介作用,这意味着董事会治理可以通过影响管理层风险认知,间接作用于企业的风险管理决策。

Editorial H-score as a metric of inner authenticity for national scientific journals—Pilot study for the field of pedagogy

There is evidence that national scientific journals are important for local communities despite their limited audience due to national languages and topics, like in pedagogy. However, it is not easy to assess the level of scientific rigour of local journals, as most do not have available scientometric data and are often published in minority languages. We hypothesize that a possible manifestation of a latent trait of inner authenticity of the scientific journal (meaning the journal is accepted by a community interested in developing the field which conducts internationally accepted research) could be H-index of the editorial board members. To test this approach, we evaluated H-index and gender of editorial board members (n = 490) from 17 Czech and Slovak national science-oriented scientific pedagogical journals which were not indexed or indexed in Erih+ or Scopus, and compared this with the five lowest-rated journals from the same field indexed in the Web of Science (WoS) database. The H-index of editorial board members was somewhat higher in indexed journals with those from WoS showing higher scores, and the number of board members with no discernable H-index was far greater in non-indexed journals. Editorial boards of journals indexed in WoS were mostly male, compared to a dominance of women on boards of non-indexed journals. Acknowledging the limited sample, it appears that the H-index of editorial board members may be a way to value national scientific journals.
