The main purpose of this study is to evaluate the extent of dropout students and identify the relationship between risk factors of dropout and the survival time of students.

The Kaplan–Meier estimator (KM), also known as the product-limit technique, is a nonparametric model function that is commonly used in estimating survival function events (Kaplan and Meier, 1958). The survival function's Kaplan–Meier estimators are used to estimate and graph survival probabilities as a function of time, as well as explanatory data analysis (EDA) for the survival data, including the median survival time, and compare for two or more of the survival events. In addition, Cox proportional hazards model is employed for modelling purpose.

Results of the Kaplan–Meier curves show that male students have lower survival rates than female, researchers have found that there is a difference between the survival times of the student's school types, results show students from English-based schools are higher than Arabic-based schools as suggested by the survival curve. Similarly, there is a difference between the survival times of students aging equal or greater than 25 and students aging less than 25 and survival function estimates of dropout according to high school grade marks has huge difference. These results were confirmed using log rank test as age, school type and marks were statistically significantly different while gender is not statistically significant.

There is no study of this kind from the Somalia context about the student's dropout. Subsequent to the outbreak of civil war in 1988 and the collapse of the central government in 1991, all public social services in Somalia including education centers were severely disrupted.

The statistical methods discussed in the previous section will be applied on a real dataset obtained from different offices of the university; most of the data were extracted from faculty of economics office and admission and record office. The data set comprised of 70 students from SIMAD university, consists of full-time faculty of economics students who enrolled at the university in the academic year of 2017–2018 until two years of diploma, students either complete 24 months of diploma or leave the university and that is the event of interest.

Public administration has become the victim of its own success. Public policy making and problem solving during the first three decades after WWII began from an assumption that public managers had the competence to overcome policy barriers. The ʼdo more with less” slogan was a statement of professional competence. It was adopted because many believed it was an affirmation of that competence. Now it represents a fiscal demand as a scold to those who will otherwise waste the money. What the public hears is a perverse joke. The goal must be more effective governance, by approaching fiscal stability as a strategic enterprise. The potential tools for more effective services exist and are applied by governments across the globe. Yet the public clings to failed practices (NPM) that are best when dealing with short-term issues

The paper presents results from the implementation and evaluation of a EU/WHO multi‐centre programme on the promotion of children's psychosocial development through primary health care services. The aims of the study were to develop methods for use by primary health care workers in their contact with families on issues pertaining to healthy psychosocial development in the first two years of life, to develop a training programme for primary health care workers to implement in their contact with the families, to evaluate the effectiveness of the programme and to promote the implementation of the developed intervention techniques through the network of primary health care services.

Cox's model with Weibull distribution and Cox's with exponential distribution are the most important models in reliability analysis. This paper seeks to show that, with a large sample size based on expectation maximization (EM) algorithm, both models give similar results.

The parameters of the models have been estimated by method of maximum likelihood based on EM algorithm. The objective of this analysis is to fit the modification of Cox's model with Weibull distribution and Cox's with exponential distribution, examine its performance and compare their results with Crowder et al.

A simulation study indicates that the parametric Cox's model with Weibull distribution gives similar results to Cox's with exponential distribution, especially for a large sample size. Also, the modification of the two models showed better results compared with Crowder et al., especially for the second causes of failure.

A modification of the two competing risk models has mostly been applied in failure time data and simulation data. The results of the simulation study indicate that the Weibull and exponential are suitable for Cox's model as they are easy to use and it can achieve even higher accuracy compared with other distribution models.

1. Innovative technologies, such as DS, can engage different human senses and play an important role in enhancing the store atmosphere.

2. The majority of DS networks feature content that is generic and is rarely tailored to the audience passing by the screens. As a result, digital displays are often ignored.

3. DS coupled with sensors and Artificial Intelligence allow for more relevant and personalized experiences.

4. Relevance through personalization can help retailers overcome display blindness, but challenges in terms of legal restrictions and ethical concerns exist to unlock its potential.

5. Nontouch interaction technologies, such as voice assistants, gesture controls, facial recognition, and augmented reality, present new ways of interacting with digital screens.

In this paper, the main objective will be to discuss the factors which can influence the usage of risk reducing strategies found in the literature over the past 30 years. Some of the factors which have relatively consistent effects include age, socio‐economic group, education while other factors show complex effect e.g. self‐confidence, loss‐type and product risk. On the whole, the literature on risk reduction and how it is affected is unable to provide would‐be researchers with clear guidance for questionnaire construction and research design.
