Research questions useful characteristics

The second research question concerns characteristics of scientific research which are related to flie need for reliable conclusions. In the pre-study texts only a minority of the students (n=7) mentioned strategies scientists and the scientific community use in order to increase the reliability of research findings. The most frequently mentioned strategies were the use of different methods (n=5) and co-operation with other researchers (n=2). 

Developed frameworks are applied to the specific industry problem to monthly plan a global chemical commodity value chain by volumes and values. Sub-objectives are to elaborate characteristics and planning requirements for a global commodity value chain in the chemical industry and to develop, implement and evaluate the respective model. Research question 2 is directed to a real industry case study demonstrating the real existence of formulated requirements, showing the applicability of the developed model in reality and evaluating the model using industry data. 

It needs to be specific (this is the same as the first characteristic of a useful research question - see Section 3.3). 

Does the new drug alter SBP more than placebo " This version of the research question has several useful characteristics ... 

Each study in a clinical development program addresses one or more research questions (we noted in the previous chapter that it is a good idea to limit the number of research questions in any given trial). In Chapter 3 we also noted two characteristics that a research question must possess to be considered useful ... 

Defining the study population is critical in determining the immediate criteria for enrollment in a clinical trial and ultimately, if the results can be apphed to the general population. The research question, hypothesis, and study design are used to identify the characteristics of participants who are eligible for the trial. 

The second research question refers to the number of variables included in the models. As stated above, impact speed is the most important predictor for injury severity and mortality. However, it is known, for example, that fatality risk can be predicted more precisely using pedestrian age in addition to impact speed [6]. Thus, considering the spectrum of variables coded in the databases, it is important to identify potential explanatory variables beyond impact speed that could improve the predictive accuracy of the models. Possible explanatory variables include vehicle kinematics (e.g., collision speed), vehicle characteristics (e.g., height of the front bumper), and pedestrian physiology (e.g., age). 

The objective of the study is to uncover the nature and characteristics, antecedents, and consequences of supply chain collaboration from multiple theoretical perspectives. To achieve this, the current study aims to shed light on the role of lOS use in supply chain collaboration by investigating the following research questions ... 

The protocol involving NaOAc-HOAc at pH 5 was first proposed and used by Jackson (1958) to remove carbonates from calcareous soils to analyze soil cation exchange characteristics (Grossman and Millet, 1961). Other researchers used HOAc for the extraction of metals from sediments and soils (Nissenbaum, 1972 Mclaren and Crawford, 1973). Tessier et al. (1979) first used the NaOAc-HOAc solution at pH 5 to dissolve the carbonate fraction from sediments. Since then, the NaOAc-HOAc buffer has been widely used as a specific extractant for the carbonate phase in various media (Tessier et al., 1979 Hickey and Kittrick, 1984 Rapin et al., 1986 Mahan et al., 1987 Han et al., 1992 Clevenger, 1990 Banin et al., 1990). Despite its widespread use, this step is not free from difficulties, and further optimization is required in its application. Questions arise with regard to this step in the elemental extraction from noncalcareous soils, the dissolution capacity and dissolution rates imposed by the buffer at various pHs, and the possibility that different carbonate minerals may require different extraction protocols (Grossman and Millet, 1961 Tessier et al., 1979). 

Scientific progress has resulted in the continual development and evolution of useful and powerful techniques, such as multiparameter flow cytometry and image analysis, to answer questions of cellular maintenance and function (and the impact chemicals may exert) for the benefit of human health. Multiparameter flow cytometry provides researchers with a capacity to simultaneously examine multiple cellular characteristics on thousands of cells in a relatively short period of time.
