地理标志农产品生产质量控制行为分析——基于新疆地理标志水果405户果农的调查

以新疆405户地理标志果农问卷调查数据为依据,运用二元Logistic回归模型对其生产质量控制行为的影响因素进行分析,结果表明：生产者的预期收益、对地理标志水果操作规程的了解程度、是否参加农民专业合作经济组织、是否得到技术指导、是否参加质量培训、政府监管力度与是否得到政府资金支持等影响因素是显著性变量。表14,参12。

Children's family change: reports and records of mothers, fathers and children compared

Family change, when adults depart or arrive around children, raises policy issues. Its measurement depends upon the evidence collected and from whom. This paper compares British children's histories obtained from fathers and mothers. The evidence, on one birth cohort of parents, comes from two sources: the National Child Development Study and the ONS Longitudinal Study. The resulting account of family change is not substantially different between parents. There is some under-reporting of children not living with their fathers. This is due to under-reporting by those included in the studies and to under-representation in them of absent fathers and lone parents.     

Design of continuous long slot leaky-wave antenna for millimeter wave application

A simple and efficient design scheme of the continuous long slot leaky-wave antenna is developed. The key steps involved in the scheme are summarized. First, the cut-off frequencies of slot waveguides with different slot offsets are obtained by 3D finite-difference time-domain (FDTD) method. Second, the attenuation function αra is estimated by the aperture distribution, and the attenuation function αrs is determined by the slot radiation.Finally, the attenuation function αra is combined with the attenuation function αrs by the coefficient K. And an example in Ka band is presented. Moreover, the return loss of the E-plane Tee-junction (ET) and the radiation pattern of leaky-wave antenna are simulated. The scheme is verified by comparing with the experimental result.

In Search of Resonance

In this paper I explore the possibility of a complementary relationship between action research and the management and systems sciences. A range of purposes that action researchers and management and systems scientists pursue is initially set out. The paper then explores whether this diversity of purposes and the ways they recommend people to proceed may come together in a new whole that is greater than the sum of its parts. A potentially useful realization of this for practice is a reflexive process of critique, choice, and action, which is elaborated on. The paper then investigates what view of holism arises from the preceeding discussions.

An analytic hierarchy process model of group consensus

In group decision making, a certain degree of consensus is necessary to derive a meaningful and valid outcome. This paper proposes a consensus reaching model for a group by using the Analytic Hierarchy Process （AHP）. It supports people to improve their group consensus level through an updating of their judgments. In this model, a moderator suggests the most discoraant aeclslon manet to update his judgment in each step. The proposed consensus reaching model allows decision makers to accept or reject the suggestion from the moderator. This model ensures that the judgment updating is effective and the final solution will be of acceptable consistency. Finally, a numerical example is given to illustrate the validity of the proposed consensus reaching model.
