A survey on CIO concerns-do enterprise architecture frameworks support them?

The challenge of IT management is today considerable. In industry, the organizational role of the Chief Information Officer (CIO) has been promoted as the owner of these challenges. In spite of a general acceptance of the problems associated with the responsibilities of the CIO, very little academic research has been conducted on the issues and constraints of this role. In order to address these shortcomings, this article presents the results of a survey in which Swedish CIOs have prioritized their most important concerns. In academia, a response to the IT system management challenges has presented itself in the discipline of Enterprise Architecture. The article argues that the CIO role is the primary stakeholder of Enterprise Architecture, so his/her need for decision support should guide Enterprise Architecture research and framework development. Therefore, the article presents a brief review over how well two existing Enterprise Architecture frameworks address the surveyed concerns of the CIO. Results from the survey indicate that the three highest prioritized concerns of CIOs are to decrease the cost related to the business organization, to improve the quality of the interplay between the IT organization and the business organization and to provide new computer-aided support to the business organization. The comparison between the CIOs' prioritization and the foci of the frameworks shows some discrepancies. The largest disharmony lies in the lack of decision support for issues related to the IT organization. Furthermore, support for explicitly estimating and managing costs is lacking within the frameworks.     

D2D通信中Chief UE应用的研究

Chief UE的作用是辅助实现D2D通信与蜂窝网络通信更好地无缝切换并且提高通信的质量。对Chief UE的概念进行了详细描述,并且对于其在切换中的作用进行了相应的阐述和论证:在传统D2D通信的基础上,定义了其中一个性质稳定良好的UE为Chief UE,进行D2D连接的内部管理和通信,并且在需要切换时,能够进行通行保持直到整个通信切换的完成和结束。将具有Chief UE的D2D切换同不具有Chief UE的D2D切换进行了相应的对比和论述,以更好地论证Chief UE存在的必要性。

When and why technology leadership enters the C-suite: An antecedents perspective on CIO presence

Building on the concept of dynamic managerial capabilities, we set out to advance scholarly understanding of the antecedents of the presence of technology leadership in the form of the chief information officer (CIO) in the top management team. We derive a holistic framework from the literature of dynamic capabilities and introduce into that literature the concept of adaptation pressures. We suggest that external and internal dimensions that pertain to information technology, comprising an environmental, structural, and strategic dimension, intensify the pressure on a firm to adapt. The pressure to adapt increases the likelihood that the firm will add a CIO to its top management team. In turn, the presence of a CIO can direct a firm toward exploration as a way to relieve the adaptation pressure. Results from regression analyses of a longitudinal data set covering 503 large U.S. firms from 2006 to 2017 confirm our hypotheses. This study contributes to the literature of both information systems and strategy by clarifying the antecedents of technology leadership in the C-suite and explicating how environmental, structural, and strategic factors can act as such antecedents. Moreover, this study reinforces the notion that IT leadership can induce strategic change.     

Characteristics of alcohol-related fatal general aviation crashes

BACKGROUND: The effects of alcohol on piloting performance have been studied extensively. Information describing alcohol-related aviation crashes, however, is scant. METHODS: We developed a data system for fatally injured pilots in Maryland, New Mexico, and North Carolina by linking autopsy data from the state medical examiner offices and crash investigation reports from the National Transportation Safety Board. Alcohol-related crashes are defined as those in which the pilot had a blood alcohol concentration of 20 mg/dL or greater. Differences between alcohol- and non-alcohol-related crashes were assessed with regard to pilot characteristics, crash circumstances, and human factors. RESULTS: The National Transportation Safety Board recorded 313 general aviation crashes fatal to the pilot in the three states between 1985 and 2000. Of these crashes, 255 (81%) were matched successfully with medical examiner records. Alcohol testing results were available for 233 of the fatally injured pilots. Of those tested for alcohol, 25 (11%) had blood alcohol concentrations > or =20 mg/dL (mean=75 +/- 64 mg/dL). The majority of alcohol-related crashes (52%) occurred at night (7p.m. to 6a.m.), compared with 28% of other crashes (P < 0.01). Alcohol-related crashes were significantly more likely than other crashes to have involved continued flight under visual flight rules (VFR) into instrument meteorological conditions (IMC) (32% versus 12%, P < 0.01), and flawed decisions (64% versus 41%, P = 0.03). CONCLUSIONS: Distinctive epidemiological patterns are exhibited in alcohol-related fatal general aviation crashes. Alcohol appears to play a particularly important role in crashes involving flight under VFR into IMC.     

Pathways to being CIO: The role of background revisited

This study examines the relationship between the background of an organization’s top information systems executive or chief information officer (CIO) and what a CIO does. It provides a somewhat different picture of the much discussed relative merits of a CIO’s background. Findings indicate that a technical background has little relationship to what the CIO does once they become CIO. Where they are hired from, however, does relate to reporting line, business focus, and how and with whom they spend their time once hired. These findings will enable more effective CIO hiring and development activities, and inform future research.

莫高窟第281窟大都督王文通供养像补正——兼论敦煌服饰研究中的一些问题

本文通过考察莫高窟第281窟的所有供养人像,认为“大都督王文通供养像”应该是窟内南壁现存隋代供养人像东起第二身,而非一直被学界认为的西壁南侧较大一身男子像。由此提出敦煌服饰研究中所使用的出版物图片或壁画临摹品等存在的一些问题,认为研究应基于对壁画本体的反复辨识,将图像置于洞窟的原生语境中进行考察,以得到更加真实而全面的结论。
