An open-graded friction course (OGFC) is a special type surface layer of traditional Dense Graded Hot Mix Asphalts (DGHMA) pavement that is increasingly being used around the world due to its various benefits, such as, frictional, safety and environmental, etc. In this research, selective laboratory OGFC properties were statistically modeled depends on mix design inputs for two purposes or aims; mix inputs significant and prediction the OGFC properties according mix inputs.  Principally, Indirect Tensile Strength (ITS), water sensitivity (TSR), and permeability (K) were selected from mechanical, durability, and volumetric properties, respectively as an output property; they represent the dependent variables for each model. While, fillers as conventional mineral filler or Ordinary Portland Cement (CMF, or OPC), binder content (BC), and polymer content (SBS) are represented inputs or the independent variables for all models. The generated models offered a vital achievable tool for prediction (e.g., their R² are 0.781, 0.82 1and 0.820, respectively, for the mentioned model’s properties), also it helped to scale the significant of each independent variable (e.g., filler type significantly affect water sensitivity properties, its correlation was 0.752). This study reveals that the statistical modeling is achievable and offers a dynamic tool to describe the characteristics and performance of OGFC mixture in term volumetric, mechanical and durability properties.

Latency is an important factor when conducting teleoperated missions. This study investigates the effects of latency on a set of dependent variables: performance (measured by time and number of errors), subjective workload, trust, and usability. These measures were tested in a simulated search-and-rescue mission over two levels of two independent variables. One independent variable was the number of robots – one or two (within-subject), and the other independent variable was latency – simulations with and without latency (between-subject.) The significant effect of the independent variables on the dependent variables were checked using repeated measure two-way ANOVA with a confidence level of 95%. The data determined any significant effects that latency and/or the number of robots had on such factors as errors, dependability, reliability, harmful outcomes, temporal demand, and frustration.

Background: Patient’s satisfaction is one of indicators measured in the hospital minimum service standards. In Installation of Inpatient (IRNA) of Haji Surabaya hospital, there are 17 indicators, but only nine are met (52.94%). One of them is patients’ satisfaction level amounted to 74.35% out of the standard (82%). The high number of complaints on nurses’ competence in providing services causes the unachieved patients’ satisfaction. There were 61 complaints from 2014 to 2017.Aim: This study aimed to analyze the influence of nurses’ responsiveness to patients’ satisfaction of in-patient installation (IRNA) at Haji Surabaya Hospital.Method: The questionnaires used Likert scale 1-5 for independent variables and dependent variables. The scoring scales for the independent variable or nurses’ responsiveness range from strongly disagree to strongly agree. Meanwhile, the scoring scale for the dependent variable ranges from very dissatisfied to very satisfied.Results: The findings indicated that there was a significant influence of responsiveness on patients’ satisfaction amounted to 0.003 (<α = 0.05). This indicated that the better assessment on the nurses’ responsiveness is, themore satisfied the patients are at in-patient installation (IRNA), Haji Surabaya Hospital.Conclusion: It can be concluded that more than 20% of responses was satisfied with the nurses’ responsiveness. The hospital needs to hold a human resource training especially a nurse-patient therapeutic communication training for maintaining the service quality at the hospital.Keywords: hospitalization, patient, responsiveness, satisfaction

Open-graded friction course (OGFC) has been used in the United States for more than 50 years. In 2000, National Center for Asphalt Technology (NCAT) research led to a recommended mix design procedure for a new-generation OGFC, but the work involved only one aggregate source. Therefore, NCAT is in the process of refining this design procedure to ensure that it is applicable to other aggregate types used in surface mixes throughout the United States. The objectives of NCAT's current research are to refine and field validate the new-generation OGFC mix design procedure. This work has led to several experiments. Several objectives have been identified that need to be addressed. Superpave® technology and use of the Superpave gyratory compactor (SGC) need to be incorporated into the mix design procedure. The Cantabro test for durability and resistance to stone loss needs to be adapted to SGC-prepared specimens and performance parameters established. The asphalt draindown test (AASHTO T 305-97), which was developed for stone-matrix asphalt mixtures, also needs to be evaluated for applicability to OGFC mixtures. In addition, a method for effectively evaluating air void criteria needs to be investigated. On the basis of the research conducted in this study, 50 gyrations of the SGC was selected as the design compactive effort during mix design. Also, the use of SGC-prepared samples during the Cantabro test appears to be a reasonable alternative to use of Marshall-compacted samples.

Conclusions regarding the relative importance of different independent variables in a statistical model have meaningful implications for theory and practice. However, methods for determining relative importance have yet to extend beyond statistical models with a single dependent variable and a limited set of multivariate models. To accommodate multivariate models, the current work proposes shifting away from the concept of independent variable relative importance toward that of parameter estimate relative importance (PERI). This paper illustrates the PERI approach by comparing it to the evaluation of regression slopes and independent variable relative importance (IVRI) statistics to show the interpretive and methodological advantages of the new concept and associated methods. PERI’s advantages above standardized slopes stem from the same fit metric that is used to compute PERI statistics; this makes them more comparable to one another than standardized slopes. PERI’s advantages over IVRI stem from situations where independent variables do not predict all dependent variables; hence, PERI permits importance determination in situations where independent variables are nested in dependent variables they predict. We also provide recommendations for implementing PERI using dominance analysis with statistical models that can be estimated with maximum likelihood estimation combined with a series of model constraints using two examples.

A relationship between human personality and preferred locations have been a long conjecture for human mobility research. In this paper, we analyzed the relationship between personality and visiting place with Poisson Regression. Poisson Regression can analyze correlation between countable dependent variable and independent variable. For this analysis, 33 volunteers provided their personality data and 49 location categories data are used. Raw location data is preprocessed to be normalized into rates of visit and outlier data is prunned. For the regression analysis, independent variables are personality data and dependent variables are preprocessed location data. Several meaningful results are found. For example, persons with high tendency of frequent visiting to university laboratory has personality with high conscientiousness and low openness. As well, other meaningful location categories are presented in this paper.

   The humor advertisement is important for every types of marketer. The main aim of the study is to analyze the impact of humor advertisement on the brand purchasing strategy of consumers. This study used descriptive research design by testing the hypothesis with dependent and independent variables. The questionnaire based survey has been undertaken upon the sample of 136 respondents. Furthermore, data analysis has been carried forward with the help of SPSS through regression and correlation. The results reveal that there is no significant relationship exists between the independent variable (humor advertisement) and the dependent variables (brand attitude, brand memories, purchase intention). There is low correlation between humor advertisement and brand attitude that shows p<0.1. Industries have been spending huge amount of money on humor advertisement but the study has also revealed that there is no significant changes in brand purchase strategy of consumer by appealing humor advertising. Test results of correlation and regression shows that humor advertisement can’t make brand purchase strategy. Therefore study of consumer behavior is important to create brand purchase strategy and spending nature of consumer towards advertised products.

Studies that analyze the actions carried out by paddle tennis players during the point are scarce. The present investigation characterizes every action in which a stroke by a pair in a defensive position sends the ball over the position of a pair in an offensive position. It is a descriptive and observational study of quantitative methodology. The sample consisted of 1324 actions, statistical analysis units, from the women’s circuit in the 2018 World Padel Tour (WPT) season. For this study, various situational, dependent, and independent variables were analyzed. The results showed the number of times the categories of each variable occurred, as well as the significant relationships between the independent variable kind of hit and the dependent variables “actions that facilitate the possible change of position” (AFPCP) and “incidences in the game” (IG). The conclusion is that the lob is the most effective kind of hit (CSR = 4.9) to achieve the offensive position (CSR = 11.4), even if the point does not finish (CSR = 5.8), leading to more position exchanges during the same point in the AFPCP. These findings are of great interest since they give information about how and why certain behaviors produce a certain result.
