Innovation Study

PurposeResponsible innovation (RI) and social innovation (SI) are two fields of innovation study experiencing burgeoning policy, practice and research interest. Despite this rapid rise in popularity, the scholarly literature in these two related areas of innovation study remains quite separate, stymieing the growth of shared research insights. The purpose of this paper is to propose a pragmatic, process-based framework that lends itself to advancing systematic research in both fields while retaining their distinct identities.Design/methodology/approachThis conceptual paper outlines an analogy-inspired framework that builds on the logical thinking put forward by Philosopher Willard Van Orman Quine in 1962. It focusses on key processes that cross-cut both fields.FindingsReflexivity, collaboration and design are identified as three broad core processes that span both the RI and SI fields and form the basis of an integrative framework that highlights the scope for cross-field research pollination.Originality/valueThe literature that draws these two fields together is virtually non-existent. The paper uses analogy to facilitate awareness of the parallels between these two areas of innovation study. The integrative framework put forward in the paper is of value for advancing cumulative research in innovation fields of critical importance to the society.

Traction Power

The existing problems of the traction power-supply system (i.e., the existence of the neutral section and the power quality problems) limit the development of railways, especially high-speed railways, which are developing rapidly worldwide. The existence of the neutral section leads to the speed loss and traction loss as well as mechanical failures, all of which threaten the fast and safe operation of the train and the system. Meanwhile, the power quality problems (e.g., the negative sequence current, the reactive power, and the harmonic) can bring a series of problems that cannot be ignored on the three-phase grid side. In response, many researchers have proposed co-phase power-supply schemes to solve these two problems simultaneously. Given that the auto-transformer (AT) power-supply mode has become the main power-supply mode for the high-speed railway traction power-supply system, it has a bright future following the rapid development of the high-speed railway. In addition, there is no co-phase power-supply scheme designed for AT power-supply mode in the existing schemes. Therefore, the main contribution of this paper is to propose a specifically designed power-supply mode more suitable for the AT, as well as to establish the control systems for the rectifier side and the inverter side. In addition, for the proposed scheme, the operation principle is analyzed, the mathematical model is built, and the control system is created, and its functionality is verified by simulation, and its advantages are compared and summarized finally. The result proves that it can meet functional requirements. At the same time, compared with the existing co-phase power-supply scheme, it saves an auto-transformer in terms of topology, reduces the current stress by 10.9% in terms of the current stress of the switching device, and reduces the power loss by 0.25% in terms of the entire system power loss, which will result in a larger amount of electricity being saved. All of this makes it a more suitable co-phase power-supply scheme for the AT power-supply mode.

This paper investigates the situation of residential kitchen ventilation and individual exposure in China and attempts to reduce the exposure through organizing local make-up airflow. Measurements were conducted in a kitchen chamber to reproduce the real exposure to the cooking-generated particles under the mode of natural make-up airflow surveyed. Measurements results show that an individual cooking in a kitchen could be exposed to a concentration of airborne particles at ∼10 mg/m3 within a simplified cooking process of oil heating, in the case of an experimental kitchen chamber with an open window or closed window/door. Local make-up airflow through upward make-up air supply or downward make-up air supply was further investigated to determine the effectiveness for reduction of the exposure level. When the air-supply velocity at the outlet of the upward make-up air supply or downward make-up air supply mode was well defined, the individual exposure level could be reduced by 2–3 orders of magnitude, as compared to the baseline case when all the make-up air was from open window. Intake fraction of cooking-generated particles could be as low as ∼10−5 and ∼10−6 under the two modes. This finding has illustrated that well-organized local make-up airflow could largely reduce an individual’s exposure to the cooking-generated particles in Chinese residential kitchen.

Cultivating students who have innovated abilities is not only an age requirement but also the focus of engineering education. In engineering education, according to the studies and practices for a very long time, this article establish "three-dimension" innovation talents development model which can improve students’ abilities of self-study and help them fit the society better after their graduation. The seven aspects are teaching method, learning approach, teaching material constructs, auxiliary answering strategy, teaching evaluation, students develop environment and innovation channels. “Three-dimensional” innovation talents development model is designed according to students’ character and their best innovation study result .And it can actually form a three-dimensional layered training model includes “General-form Teaching”, “Extensions Expand” and “Elites Cultivating”. The effect of the practice of "three-dimensional" innovation talents development model is very obvious.

Knowledge integration played a major and centre role in the process of organizations knowledge innovation. Study on the knowledge integration contents and process in organization has important significance. There are four contents of knowledge integration in organization knowledge innovation: knowledge integration between different knowledge main bodies; different knowledge levels; the new and original knowledge system; personal study, team study and organization study. The paper discussed the process of knowledge integration toward organization knowledge innovation based on lify-cycle theory and divided the process into four stages: embryonic stage, development stage, mature stage and diffusion stage. The paper analyzed the knowledge value in different life cycle stages and the result indicates that the knowledge in mature stage is the most valuable.
