The dependent variable

This study proposes the application of Ensemble Decision Tree Boosted (EDT Boosted) model for forecasting the surface chloride concentration of marine concrete Cs. A database of 386 experimental results was collected from 17 different sources covering twelve variables was used to build and verify the predictive power of the EDT model.

The focus of this study is to investigate its optical and conductive properties under different conditions of doping environments, temperature and polymerization conditions. Optical characterization technique such as UV-Visible spectroscopy is developed to carry out the investigation. The developed nanofibers have been demonstrated to possess optical and conductive properties to be dependent on doping variables. Study of these optical properties could prove very useful in the development of electrochromic devices and gas sensors.

This study has explored the impact of the community integration of ATDs (Australian Trained Doctors) and OTDs (Overseas Trained Doctors) in rural and remote communities on their quality of life (QOL) and its resultant effect on their retention by developing a model of research linking QOL as the intervening variable between community integration (the independent variable) and retention (the dependent variable). A national survey of 279 rural and remote GPs was conducted between September and December 2010.

The scope of research examining the meaning and meaningfulness of work is rather broad; I therefore believe it is necessary to first provide an overview of research approaches before describing my own approach. Depending on the definition of the concept of the meaning of work they used, researchers took various approaches. According to one group of researchers, the meaning of work and the meaningfulness of work is necessarily a subjective matter, with the meaning of work defined intrinsically (coming from the individual) (e.g. Simon, 1997; Isaksen, 2000).

In addition, one of the attributes of microcredit programs is that the target clients are women. Therefore, this research also investigates the role of gender in participation in microcredit. In particular, this research examines whether the female household heads can have better accessibility to microcredit sources than the male counterparts. This objective is conducted using models with binary dependent variable such as Probit or Logit.

These results even led to running a second regression with a change in the independent and dependent variable to gain more insights. Although there is much information about facility spending and the rising expenses in college athletics, there is not much correlational data to date. The results from this study can help give collegiate athletic departments more information and a more holistic picture of the relationships between these important variables before they start investing in a new major facility.

Human immunodeficiency virus type 1 protein R (HIV-1 Vpr) promotes nuclear entry of viral nucleic acids in nondividing cells, causes G2 cell cycle arrest and is involved in cellular differentiation and cell death. Vpr subcellular localization is as variable as its functions. It is known, that consistent with its role in nuclear transport, Vpr localizes to the nuclear envelope of human cells. Further, a reported ion channel activity of Vpr is clearly dependent on its localization in or at membranes.

Endoplasmic reticulum-associated degradation of newly synthesized glycoproteins has been demonstrated previously using various mammalian cell lines. Depending on the cell type, glycoproteins bearingMan9 glycans and glycoproteins bearing Man5 glycans can be efficiently degraded. Awide variety of variables can lead to defective synthesis of lipid-linked oligosaccharides and, therefore, in mammalian cells, species derived fromMan9GlcNAc2 orMan5GlcNAc2 are often recovered on newly synthesized glycoproteins. ...

CONSTRUCTION OF UPPER AND LOWER SOLUTIONS FOR SINGULAR DISCRETE INITIAL AND BOUNDARY VALUE PROBLEMS VIA INEQUALITY THEORY ¨ HAISHEN LU AND DONAL O’REGAN Received 25 May 2004 We present new existence results for singular discrete initial and boundary value problems. In particular our nonlinearity may be singular in its dependent variable and is allowed to change sign. 1. Introduction An upper- and lower-solution theory is presented for the singular discrete boundary value problem −∆ ϕ p ∆u(k − 1) = q(k) f k,u(k) , k ∈ N = {1,...

AN ASYMPTOTIC RESULT FOR SOME DELAY DIFFERENCE EQUATIONS WITH CONTINUOUS VARIABLE CH. G. PHILOS AND I. K. PURNARAS Received 14 October 2003 We consider a nonhomogeneous linear delay difference equation with continuous variable and establish an asymptotic result for the solutions. Our result is obtained by the use of a positive root with an appropriate property of the so-called characteristic equation of the corresponding homogeneous linear (autonomous) delay difference equation.

Dependent variable: The measure of change observed because of the independent variable. It is important to decide how you are going to measure the change.
