文章选取浙江大学管理学院为对象,研究了高校会计数智化培养改革演变过程中的意义建构范式。研究发现,案例对象的改革演进先后经历了人才改革培养方案制定、智能财务专业成立起步、产学研贯通协同育人等三个阶段,各阶段的意义建构范式分别是:受限的意义建构、介于受限与导向明确之间的意义建构、导向明确的意义建构。研究认为:意义建构活动能够提升各利益相关方的认知,并以此为指导,调整人才培养实施行为,进而影响到高校会计数智化人才培养改革的实施效果;其中,促发因素表现出由外到内,由被动到主动,由短期到可持续的演变规律;意义建构的控制主体表现出逐步下沉,控制程度逐渐降低,控制作用非线性的变化规律;意义建构的接受主体呈现出活跃度由低向高、由管理层向基层教师、由学校向校外企业逐渐转化的变化规律。

In engineering applications, probabilistic reliability theory appears to be presently the most important method, however, in many cases precise probabilistic reliability theory cannot be considered as adequate and credible model of the real state of actual affairs. In this paper, we developed a hybrid of probabilistic and non-probabilistic reliability theory, which describes the structural uncertain parameters as interval variables when statistical data are found insufficient. By using the interval analysis, a new method for calculating the interval of the structural reliability as well as the reliability index is introduced in this paper, and the traditional probabilistic theory is incorporated with the interval analysis. Moreover, the new method preserves the useful part of the traditional probabilistic reliability theory, but removes the restriction of its strict requirement on data acquisition. Example is presented to demonstrate the feasibility and validity of the proposed theory.

超声内镜检查术(endoscopic ultrasound,EUS)已广泛应用于多种消化系统疾病的诊治,但其对微血管血流及组织灌注判断方面的局限性也限制了其进一步发展。随着第二代造影剂的出现,造影增强谐波超声内镜检查术(contrast-enhanced harmonic endoscopic ultrasound,CH-EUS)技术也应运而生,其在微血管的可视化、局灶性良恶性病变的鉴别、肿瘤的分期以及疾病治疗的指导等多个方面均表现出巨大的应用潜力。对CH-EUS在胃肠道上皮下病变、胰腺病变、胆道疾病、内脏血管疾病及腹腔淋巴结相关疾病等多种消化系统疾病诊断中的应用及最新研究进展作一综述。

The analytical solution for an annular plate rotating at a constant angular velocity is derived by means of direct displacement method from the elasticity equations for axisymmetric problems of functionally graded transversely isotropic media. The displacement components are assumed as a linear combination of certain explicit functions of the radial coordinate, with seven undetermined coefficients being functions of the axial coordinate z. Seven equations governing these z-dependent functions are derived and solved by a progressive integrating scheme. The present solution can be degenerated into the solution of a rotating isotropic functionally graded annular plate. The solution also can be degenerated into that for transversely isotropic or isotropic homogeneous materials. Finally, a special case is considered and the effect of the material gradient index on the elastic field is illustrated numerically.

A study on the zero-forcing beamforming （zFBF） scheme with antenna selection at user terminals in downlink multi-antenna multi-user systems is presented. Simulation results show that the proposed zFBF scheme with receiver antenna selection （zFBF-AS） achieves considerable throughput improvement over the zFBF scheme with single receiver antenna. The results also show that, with multi-user diversity, the zFBF-AS scheme approaches the throughput performance of the zFBF scheme using all receiver antennas （zFBF-WO-AS） when the base station adopts semi-orthogonal user selection （SUS） algorithm, and achieves larger throughput when the base station adopts the Round-robin scheduling algorithm. Compared with zFBF-WO-AS, the proposed zFBF-AS scheme can reduce the cost of user equipments and the channel state information requirement at the transmitter （CSIT） as well as the multiuser scheduling complexity at the transmitter.

职业教育教师激励机制对促进教师自我实现、赋予职业教育特定的价值理念、推动社会对职业教育类型属性的认可和促进职业教育教师身份的自我认同具有重要作用。以双因素理论为支撑,职业教育教师激励机制要不断满足保健因素,减少或消除教师的不满情绪;强化激励因素,激发教师的主动性、积极性和创造性。在具体实践中,职业教育教师激励机制的实施需要按照职业教育类型化认知形成激励机制建设的根本导向,根据职业教育教师的发展需求形成激励机制建设的诱导性因素,建立符合职业教育教师激励机制发展所需要的激励制度架构,探索“指导—服务”式的整体激励机制运行推进策略并提供全方位的激励机制实施支持保障。

The macroscopic deformed potential energies for super-heavy elements z = 110,112,114,116,118 are determined within a generalized liquid drop model (gLDM). A quasi-molecular mechanism is introduced to describe the deformation of a nucleus in the gLDM and the shell model simultaneously. The macroscopic energy of a twocenter nuclear system in the gLDM includes the volume-, surface-, and Coulomb-energies, the proximity effect at each mass asymmetry, and accurate nuclear radius. The shell correction is calculated by the Strutinsky method and the microscopic single particle energies are derived from a shell model in an axially deformed Woods-Saxon potential with the quasi-molecular shape. The total potential energy of a nucleus can be calculated by the macro-microscopic method as the summation of the liquid-drop energy and the Strutinsky shell correction. The theory is applied to predict the fusion barriers of the cold reactions 64Ni + 208Pb → 272110*, 70zn + 208Pb → 278112*, 76ge + 208pb → 284114*,82Se + 208Pb → 290116*, 86Kr + 208Pb → 294118*. It is found that the neck in the quasi-molecular shape is responsible for the deep valley of the fusion barrier. In the cold fusion path, double-hump fusion barriers could be predicted by the shell corrections and complete fusion events may occur.
