Application of qualitative research in management (why, when and how) Qualitative research has been increasingly used in all sciences. In this paper we will discuss about the applications of qualitative research methods in management sciences. The differences between quantitative and qualitative researches will be clarified and the statistical methods which are suitable for such researches will...

Whole-body averaged specific absorption rate (WBASAR) is used as a metric for human protection from whole-body exposures. The frequency at which the WBA-SAR becomes maximal is called “resonance frequency”. The present study proposes a scheme to estimate WBA-SAR at the resonance frequency based on an analogy between a human and a quarter-wavelength monopole antenna. Specifically, WBA-SAR can be ...

Currently, the best performing models for Chinese word segmentation (CWS) are extremely resource intensive in terms of annotation data quantity. One promising solution to minimize the cost of data acquisition is active learning, which aims to actively select the most useful instances to annotate for learning. Active learning on CWS, however, remains challenging due to its inherent nature. In th...

This essay focuses on metadiscourse, a name for elements of texts that convey meanings other than  those  that  are  primarily  referential.    The  essay  provides  some  theoretical  background  to the  study  of  metadiscourse,  briefly  reviews  a  taxonomy  of  metadiscourse,  and  explores  four reasons why the study of metadiscourse is interesting and important: (a) Such study shows how ...

most people are interested to know the effects of hazards on their life, health and environment. we have decided to answer the question “why hazards science?” in each issue of the journal. the necessity of raising this question isn’t based on the activity of the present magazine entitled hazards science (though the scientific approach we adopt here is a new combined approach), but the numerous ...

data envelopment analysis (dea) is an efficient method to perform evaluation of units. in dea we try to evaluate units with undesirable factors in input & outputs by satisfaction function, testing some models. on the other hand benefiting this concept, we can identify non-efficient units. also we can recognize why these units are inefficient and calculate the reason of their inefficiency and ho...

In this paper we discuss the Wireless Mesh Network developed in the scope of the IBBT Wireless Building Automation project. This WMN is designed as a high datarate wireless backbone interconnection between the other wireless networks used in the WBA architecture. We will demonstrate that switched Ethernet is a technology that, with minimal effort, can be used as a base for WMNs. We will also ta...
