Analyzing Job Tenure Factors in Private and Public Companies in Albania by Using Cox Proportional Hazards Model

A R T I C L E I N F O A B S T R A C T Article history: Received: 04 December, 2019 Accepted: 23 January, 2020 Online: 20 March, 2020 Job tenure is an important factor for both employees and employers. Sometimes, for employees, this time is a criterion in starting new job, and also for employers when they have to hire new employees. It measures the length of time that employees have been in their current job or with their current employer. Analyzing factors, which affect the job tenure, is important for companies, as well as for employee. Job tenure is a duration concepts, so we have applied survival analysis to model the tenure for Albanian employees, in several different private and public companies. First, Kaplan-Meier method is used to estimate the survival function for time. Then Cox proportional hazards model is used to assess the impact of the predictors in job termination. This study demonstrated the important role that the current age of the employee, the age at which he started the job, salary, gender, position, education, marital status and years of work in front of the current position may have on job tenure.
Transient Thermal Analysis in an Intermittent Ceramic Kiln with Thermal Insulation: A Theoretical Approach

Increasing the thermal efficiency of drying and firing processes of ceramic products plays an important role for industries that want to remain competitive in the market. Thus, this work aims to evaluate the influence of the type and thickness of thermal insulations, applied on the external sidewalls of an intermittent ceramic kiln, on heat transfer, temperature distribution in the insulating material, maximum external surface temperature, and energy gain, compared to the kiln without thermal insulation. All proposed mathematical formulations are based on the energy conservation, and mathematical procedures are implemented in Microsoft Excel software. Here, it was tested four types of thermal isolators: fiberglass, rockwool, calcium silicate, and ceramic fiber. Results indicate that the greater the thickness of the thermal insulation, the lower the maximum external surface temperature and the greater the energy gain when compared to the kiln without thermal insulation. In addition, fiberglass is the insulating material, among the four types analyzed, which provides greater energy gain and greater reduction in maximum external surface temperature.

The Ping Pong Robot to Return a Ball Precisely ~ Trajectory Prediction and Racket Control for Spinning Balls

We are developing a ping-pong robot “FORPHEUS” that can play table tennis with humans representing the harmony between humans and machines. In order to accurately return the ping-pong ball, the robot must perform the following tasks: predicting the trajectory of the ball before and after hitting the racket and determining the movement of the racket (velocity and direction to return the ball). The spin of the ball must be taken into account in those tasks because it has a major impact on the ball trajectory and the racket movement. However, we could not consider the effect of the ball spin because a standard industrial camera (80 fps) which doesn't have sufficient flame rate is being used. Therefore, we propose a new method to estimate the rotational velocity of the ball with a standard flame rate camera and how to improve the accuracy of the return point. For the sake of the proposed method, the ping-pong robot can return 36.5 cm more accurately than the conventional one. As a result, human-machine harmony increases, especially for ping-pong beginners.
IMPACT OF ORGANIC CHROMIUM ON SOME PRODUCTIVE PERFORMANCES AND PHYSIOLOGICAL RESPONSES OF GROWING BARKI LAMBS

This study was conducted to evaluate the effect of chromium methionine on some productive performances and physiological responses of growing Barki lambs. Thirty-three lambs averaged 35.37 kg body weight; 5 months old were divided into 3 similar groups of 11 animals according to their live weight. The three groups were assigned at random to the three experimental groups as follow: G1: control ration without chromium, G2: control ration with 1.50 mg chromium/head/day, G3: control ration with 3 mg chromium/head/day. The growth trial was conducted for 90 days. Lambs were weighed every two weeks before morning feeding after 15 h of fasting. Body weight gain was recorded and daily feed intake was calculated. Dry matter (DM), total digestible nutrients (TDN) and digestible crude protein (DCP) intake were calculated. Feed efficiency ratio was calculated. Results indicated that, either G2: 1.50 mg /head/day or G3: 3 mg /head/day Cr supplementation had no effects on the digestibility of DM, OM, CP , EE and DCP, but G3 (3 mg /head/day). But had significant (P<0.05) increase on digestibility of CF, NFE and TDN compared with G2 and control group. At the same time Cr supplementation did not affect onglobulin, creatinine, ALT and AST in blood plasma. Furthermore, no effect on urea. At the same time G3 (3 mg /head/day) Cr supplementation led to increase protein, albumin and blood glucose compared with G2 and control group. In addition, Cr supplementation had no effects on rumen pH, Total volatile fatty acids (TVFA’s) and ammonia concentrations at zero time and at 4 hours post feeding. At the same time G2 (1.50 mg /head/day) or G3 (3 mg Cr/head/day) had significant (P<0.05) increase total weight gain and average daily gain. Thus, Cr supplementation in G2 and G3 improved feed efficiency. From the present results it can be concluded that supplementation of Cr in organic form led to positive effect on deferent performances as a result of improving physiological responses.
Clinical and Morphological Profile in Breast Carcinoma Patients in a Tertiary Care Hospital, SMS Medical College, Jaipur, Rajasthan Authors

Objectives: Breast cancer is the most common malignancy in females. Data on breast cancer profile of patients in Rajasthan is scant. Patients have different clinical and morphological presentation and each case require appropriate strategy for screening, diagnosis and treatment purpose. This study is conducted to find out clinical stage at which the patients presented, to assess the clinicomorphological spectrum of breast cancer patients and to correlate histological grade (Richardson bloom score) with clinical stage of disease. Method: This prospective study was carried out on 100 newly diagnosed cases of breast carcinoma. Every eligible surgical specimens of breast carcinoma received in department of pathology. Results: Mean age of patients was found to be lower compared to western countries. Many of the patients were from rural background and patients often presented with longer duration of symptoms and advanced clinical stage. Left side was more frequently involved. The tumour was commonly of higher grade . The more advanced stages were associated with higher grade at time of diagnosis. Conclusion: Breast cancer occurs in younger age females in India including Rajasthan. Considering the younger age of presentation and decreased affordability of patients, mammography might be a less effective screening test due to higher density of breast in young age, which decreases the sensitivity of mammography. Patients are mostly from rural background and present more frequently with advanced stage breast cancer. Most Patients presented with advanced stage of breast carcinoma. A statistically significant positive correlation was seen between Histological grade and clinical stage of breast cancer. Awareness campaigns, breast self-examination, improved access to diagnostic resources and health care are important measures that should be undertaken for early diagnosis particularly in rural areas.
Intelligent Parallel Mixed Method Approach for Characterising Viral YouTube Videos in Saudi Arabia

In social networking platforms, comprehending vi-rality, exemplified by YouTube, is of great importance, which helps in understanding what characteristics utilised to create content along with what dynamics involved in contributing to YouTube’s strength as a platform for sharing content. The current literature surrounding virality problem appears sparse concern-ing development theories, investigations regarding empirical facts, and an understanding of what makes videos go viral. The over-arching objective is to understand deeply the phenomena of viral YouTube videos in Saudi Arabia, hence we propose an intelligent convergent parallel mixed-methods approach that begins, as an internal step, by a qualitative thematic analyses method and an NLP-based quantitative method independently, followed by training an unsupervised clustering model for integrating the internal analysis outputs for deeper insights. We have empirically analysed some trended YouTube videos along with their contents, for studying such phenomena. One of our main findings revealed that boosting entertainments, traditions, politics, and/or religion issues when making a video, that is associated in somehow with sarcastic or rude remarks, is likely the preeminent impulse for letting a regular video go viral.

The aim of the Primitive Feature Extraction (PFA) project 1 is to demonstrate that feature extraction and analysis of EO data makes it possible to exploit the large volumes of various types of satellite data more efficiently, and through this to foster the scientific analysis of mission wide data sets. The project addresses emerging methods and tools for data product features and information extraction, in view of possible implementations for enriching data description and easing the use of archived data[1]. For this purpose, a number of EO data exploitation scenarios are being implemented to test the possibility of systematically extracting EO product features and demonstrate the usefulness of the performed feature extraction in the data selection process, both for the scientist and for the users of EO products. The project has selected to implement feature extractors for forest mapping, urban mapping, algal blooms and flood mapping. The entire EO archives from optical and SAR sensors will be processed using the ESA toolboxes BEAM and NEST[2] on the Calvalus Hadoop cluster[3]. Products are searched using content based image retrieval (CBIR) on single images and time series images[4].
DOES DIFFERENTIATION STRATEGY MODEL MATTER? DESIGNATION OF ORGANIZATIONAL PERFORMANCE USING DIFFERENTIATION STRATEGY INSTRUMENTS – AN EMPIRICAL ANALYSIS

Considering pursuing the differentiation strategy makes enable the organization to earn its success and to create, capture and sustain economic value. Despite this importance, it is relatively absentminded in empirical studies at the conceptual level. In response to this gap, the purpose of this paper is conceptualizing differentiation strategy model, developing the instruments of differentiation strategy, and testing the relationship between dimensions of the value chain, differentiation in the supply, competitive advantages, and organizational performance, using data from a sample of 123 manufacturing organizations. On this study, quantitative methods were applied to measure the proposed relationships, and questionnaires were used as a tool in gathering primary data. Relationships proposed in the framework were tested using structural equation modeling. The results of this study indicated that pursuing the differentiation strategy leads on increasing competitive advantage and improving organizational performance. Also, it pointed out that the manufacture organizations’ success is determined by their ability to be flexible on strategic planning and on integrating internal and industrial settings factors on differentiation strategy creating. This research contributes to strategic literature clarifying a successful differentiation model helping the practitioners on increasing the ability and knowledge on pursuing the differentiation strategy.
Attacks Classification and a Novel IDS for Detecting Jamming Attack in WBAN

A R T I C L E I N F O A B S T R A C T Article history: Received: 01 January, 2020 Accepted: 16 February, 2020 Online: 09 March, 2020 Wireless Body Area Network (WBAN) aims to monitor patient’s health remotely, by using mini medical sensors that are attached on the human body to collect important data via the wireless network. However, this type of communication is very vulnerable to various types of attacks, poses serious problems to the individual’s life who wears the nodes. In this paper, we present a new classification of the most dangerous attacks based on different criteria, which gives us a clear vision of how attacks affect a WBAN system. Moreover, this classification will help us to specify the strength and the weakness of each attack in order to facilitate the development of a new intrusion detection system (IDS). In the second part of this work, we develop a novel IDS for detecting three types of jamming attacks in WBAN. The proposed methodology is based on the network parameters as an indicator to differentiate the normal case from the abnormal case like false alert or attack state. Through simulation analysis that was applied on Castalia platform by using OMNET++ as a simulator, proves that the proposed IDS have a great effect for detecting the presence of jamming attack in the network.
PC VIRUS ATTACKS IN SMALL FIRMS: EFFECTS OF RISK PERCEPTIONS AND INFORMATION TECHNOLOGY COMPETENCE ON PREVENTIVE BEHAVIORS

While Information Technology (IT) is undeniably useful in improving organizational efficiency, it is also vulnerable: a virus attack can interrupt the work of many employees. Human behaviors, practices and errors are possible causes of a computer virus attack and the consequent infections. Even if preventive behavior is studied in health psychology and other fields, the prevention of personal computer (PC) virus attacks is a fairly new area of research. In this study it is hypothesized that both risk perception of actions that might cause a virus attack and IT self-rated competencies influence the implementation of behaviors aiming to prevent virus attacks. It is also hypothesized that risk perception is related to IT competencies. Employees ( (cid:1) = 134) working in four organizations participated in the study by completing a questionnaire. Structural equation modeling was used to test the model. Results show that risk perception does not have a significant effect on preventive behaviors; in contrast, IT competencies influence the actual preventive behaviors and are related to the perception of risk of virus attacks.
EFFECT OF SOWING DATE VIS-A-VIS VARIETY OF RAPESEED AND MUSTARD ON GROWTH, YIELD AND APHID INFESTATION IN GANGETIC PLAINS OF WEST BENGAL

Oilseed and oil has assumed an importance of their own in the economy of the country as well as in the life of people for balanced nutrition. Among the different oilseed crops, rapeseed and mustard holds a key place in Indian agriculture. In West Bengal, it is the most important oilseed crop occupying an area of 4.1 lakh hectares with a production of 4.20 lakh tonnes (Anonymous, 2012). The predominant rapeseed and mustard varieties of West Bengal are B-9 and B-85 respectively with an average yield of 1021 kg ha (Anonymous, 2012). These varieties are very old and needed to be replaced by the new high yielding varieties. In Gangetic plains of West Bengal where winter is short and cropping intensity is high, the choice of rapeseed and mustard variety is very critical. In this case cultivation of improved short duration high yielding varieties of rapeseed and mustard can be the solution to increase the production (Ozer and Oral, 1997; Sharma and Manchanda, 1997) and make the rapeseed and mustard cultivation more profitable.

Objectives: This study aimed to identify and study most properties of the specific and general health-relatedquality-of-life (HRQoL) in prostate cancer patients, as well as creating a new measurement scale for assessing QoLamong prostate cancer patients.Methodology: A cross sectional (descriptive) study was conducted to evaluate General Quality of life in patientswith prostate cancer. A sample of 100 prostate cancer patients from Al-Amal National hospital for cancermanagement and Oncology Center in Baghdad Medical City. This study applied format of General World HealthOrganization Quality of Life-BERF questionnaire. The methods used descriptive statistics to evaluate the GeneralQoL-Improvements, as well as inferential statistical methods were used such that (Wilcoxon Signed Rank,McNemar). Results: Patients with prostate cancer have different assessment concerning general QoL, and have instability oftheir daily life cycle, within a moderate level. Regarding Specific QoL, overall result showed moderate assessmentof quality of life,nbut some domains showed worse assessment than others specially (sexual confidence, sexualintimacy and prostate specific antigen (PSA) concern domains). Other domains accounted moderate responses andthose were (urinary control, masculine and self-esteem, heath worry, cancer control, informed decision and outlook),while (marital affection, sexual intimacy and regret) accounted high responding, therefore, prostate cancer patientshave instability of their daily life cycle, within a moderate level. A new measurement scale was created using factoranalysis technique on WHO HRQoL BREF and specific HRQoL of prostate cancer patients
CMTC-486622-MS Surfactant and a Mixture of Surfactant and Nanoparticles Stabilized- CO2/Brine Foam for Gas Mobility Control and Enhanced Oil Recovery

Injecting carbon dioxide (CO2) into oil reservoirs has the potential to enhance oil recovery (EOR) and mitigate climate change by storing CO2 underground. Despite successes in using CO2 to enhance oil recovery, mobility control remains a major challenge facing CO2 injection projects. The objective of this work is to investigate the potential of using surfactant and a mixture of surfactant and nanoparticles (NPs) to generate foam to reduce gas mobility and enhanced oil recovery. A newly developed anionic surfactant and a mixture of the surfactant and surface modified silica NPs were used to assess the ability of generating a stable foam at harsh reservoir conditions: sc-CO2 and high temperature. Dynamic foam tests and coreflood experiments were conducted to evaluate foam stability and strength. To measure the mobility of injected fluids in sandstone rocks, the foam was generated by co-injection of sc-CO2 and surfactant, as well as a mixture of surfactant and NPs at 90% quality. The coreflood experiments were conducted using non-fractured and fractured sandstone cores at 1550 psi and 50C. Surfactant alone and mixtures of surfactant and NPs were able to generate foam in porous media and reduce CO2 mobility. The mobility reduction factor (MRF) for both cases was about 3.5 times higher than that of injecting CO2 and brine at the same conditions. The coreflood experiments in non-fractured sandstone rocks showed that both surfactant and a mixture of surfactant and NPs were able to enhance oil recovery. The baseline experiment in the absence of surfactant resulted in a total recovery of 71.50% of the original oil in place (OOIP). Using surfactant brought the oil recovery to 76% of the OOIP. The addition of NPs to surfactant resulted in a higher oil recovery still, 80% of the OOIP. In fractured rocks, oil recoveries during secondary production mechanisms for the mixture, the surfactant alone, and sc-CO2 alone were 12.62, 8.41 and 7.21% of the OOIP, respectively. Large amounts of oil remain underground following primary and secondary oil production schemes. CO2 has been widely used to enhance oil recovery. However, its high mobility might result in unfavorable and unsuccessful projects. The use of specially designed surfactants and the synergistic effect of surfactant
Validation of an Instrument and Measurement of Employee Work-Life Policies, Psychological Empowerment, and Job Commitment of Academic Staff in Universities

This study used a structural equation modelling approach to assess the association between employee work-life policies, psychological empowerment, and academic staff job commitment in universities in Cross River State, Nigeria. Three null hypotheses were formulated to guide the study following a descriptive survey research design. Multistage sampling procedure was adopted in the selection of 315 academic staff from two universities in the study area. “Work-Life Policies, Psychological Empowerment and Job Commitment Questionnaire (WPPEJCQ)” was used as the instrument for data collection. The construct validity of the instrument was ascertained through an Exploratory Factor Analysis (EFA) using the Principal Component Analysis (PCA). The Kaiser-Meyer-Ohlin of . 894 and the Bartlett coefficient of 7795.820 were obtained. Several fit indices of Confirmatory Factor Analysis were used to accept the model such as RMSEA=. 031, TLI=. 969, CFI=. 971 and many others. The null hypotheses were all tested using Path analysis. Findings revealed, among others, that there is a significant effect of work-life policies on the affective (β=.774,t=21.636,p<.05), continuance (β=.450,t=8.932,p<.05), and normative (β=490,t=9.967,p<.05) dimensions of academic staff commitment; furthermore, psychological empowerment has a significant effect on the affective (β=.795,t=23.199,p<.05), continuance (β=.501,t=10.261,p<.05) and normative (β = .520, t = 10.795, p< .05) dimensions of staff commitment; and there is a significant composite effect of work-life policies and psychological empowerment on the affective, continuance, and normative commitment levels of academic staff in universities. Based on these findings, conclusions and recommendations were made
Application of Double Hurdle Model on Effects of Demographics for Tea Consumption in China

The purpose of this study is to investigate the effects of demographic variables on tea consumption in China. A total of 12,745 samples collected from the China Health and Nutrition Survey in 2011 and a double hurdle model were used to analyze the effects of demographic variables on the extent of tea participation and consumption quantity for men and women. The results of this study indicate that the effects of demographic variables differ between genders in terms of tea participation decisions and consumption quantity decisions. For men, education, family size, region, and employment status were found to exert different effects on participation and consumption quantity decisions; for women, age, education, region, employment status, having elderly individuals in the home, and urbanization exerted different effects on their tea participation and consumption decisions. The most obvious difference between variables affecting men and women pertained to age, family size, and having elderly individuals in the home. The perspectives of each gender, coupled with the double hurdle model used in this study, offer important insights.
