Influence Analysis of Dissatisfaction , Situational Condition , and Switching Costs on the Switching Behavior of Telkomsel Postpaid Card Customers in Batam City

The intense competition in the Indonesian telecommunications industry has resulted in a price war and then raises the level of consumer churn. Churn is a representation of switching behavior from consumers. Switch Behavior is caused by three factors namely consumer dissatisfaction, perceptions of situational conditions, and switching costs. This study aims to determine the significance of the influence of these three factors on the switching behavior of postpaid card Telkomsel’s customers in Batam city. Population in this research is all Telkomsel telecommunication service consumers residing in the geographical area of Batam. The method of determining the sample is quota sampling with a sample size of 400 samples, and data collection was done through a questionnaire. Testing research hypothesis was done using logistic regression analysis technique with SPSS 24.0 version software tool. The result of the research shows that: (1) consumer dissatisfaction has a significant influence on switching behavior Telkomsel’s postpaid subscriber in Batam city, (2) perception of situational condition has a significant influence on switching behavior of Telkomsel postpaid customer in Batam city. (3) Switching cost does not have a significant effect on switching behavior of Telkomsel’s postpaid subscriber in Batam city. 4) The greatest influence factor is the predictor of situational conditions. 5) In relation to the results where switching costs have no significant effect on switching behavior of Telkomsel’s postpaid subscriber in Batam city, it becomes very significant when it comes to procedural and financial switching costs. It is strongly suspected due to the relational switching cost. The result of this research can help the telecommunication industrial management to state the right marketing strategy to win the competition on the telecommunication industrial market especially in Batam city. In connection with the results and discussion in this study, it is expected that further research should examine more specific indicators of dissatisfaction and focus on the dimension of the response of service failure. In addition, it is hoped that further research will be conducted to find other factors that also contribute to the effect of switching behavior to obtain a more complete model of consumer switching.
Impact of the Parameterization of IEEE 802 . 15 . 4 Medium Access Layer on the Consumption of ZigBee Sensor Motes

This paper presents an analysis of the impact that the parameterization of the CSMA/CA algorithm (employed by IEEE 802.15.4 Medium Access Layer) has on the consumption of ZigBee motes. For this purpose, the study introduces an analytical model that permits to compute the mean drain current of low duty cycle sensor motes. The results show that the energy required by the re-association process required after a packet loss cannot be neglected when setting the values of CSMA/CA parameters. Keywords-IEEE 802.15. 4, ZigBee, CSMA/CA
Triangle-free reserving

Abstract This paper argues that all reserving methods based on claims triangulations (the “triangle trick”), no matter how sophisticated the subsequent processing of the information contained in the triangle is, are inherently inadequate to accurately model the distribution of reserves, although they may be good enough to produce a point estimate of such reserves. The reason is that the triangle representation involves the compression (and ultimately the loss) of crucial information about the individual losses, which comes back to haunt us when we try to extract detailed information on the distribution of incurred but not reported (IBNR) and reported but not settled (RBNS) losses. This paper then argues that in order to avoid such loss of information it is necessary to adopt an approach which is similar to that used in pricing, where a separate frequency and severity model are developed and then combined by Monte Carlo simulation or other numerical techniques to produce the aggregate loss distribution. A specific implementation of this approach is described, whose core feature is a method to produce a frequency model for the incurred but not reported claim count based on the empirical distribution of delays (delay = the time between loss date and reporting date), after adjustments to make up for the bias towards smaller delays. The method also produces a kernel severity model for the individual losses, from which the severity distribution of each year of occurrence can be derived. By combining the frequency and severity model in the usual way (e.g. through Monte Carlo simulation), an aggregate model for IBNR and UPR losses can be produced. As for RBNS losses, we suggest using one of the many methods to analyse the distribution of IBNER (incurred but not enough reserved) factors to produce a possible distribution of outcomes. A case study based on real-world liability claims is used to illustrate how the method works in practice. Also, in a first step towards validating the method for calculating IBNR and comparing it with existing methods, a series of experiments with artificial data sets was undertaken, which show a drastic reduction in the prediction error of both the IBNR claim count and the IBNR total amount with respect to the standard chain ladder method. And what is perhaps most promising, the experiments show that the distribution of IBNR reserves is much closer (in terms of the Kolmogorov-Smirnov distance) to the “true” one than that based on Mack's method in the way it is normally applied. The method promises therefore a more accurate assessment of the uncertainty around reserves.
IMPACT OF RANDOM BROADCAST OF THE INTERNET ON HUMAN HEALTH : A FIELD STUDY ON AL-NAJAF CITY

Demands of the Internet services have been increased and grown in the last one decade. Due to absence and weakness of the fiber optic infrastructure in some countries like Iraq. Thus, most of the Internet Service Provider (ISP) used alternative solutions such as wireless broadcasting via central towers based on free frequencies wireless devices ( broadband). Concern on the spread of wireless internet services is growing, considering the lack of control and regulation of this technology, particularly with the plenty of reports of illnesses associated with Wireless Broadcasting and spread devices used for internet broadcast in homes and companies. In this work, we conducted field measurements in an Iraqi city that has more than 1250 towers within 28824 km2. This area is large but is mostly an empty desert, so the concentration of these towers is only about 500 km2. All towers use a free license frequency (5 GHz) to broadcast the internet. The present study took 63 days to finish. It started on 6th October and finished on 7th December. The obtained measurements were compared with international standards of wireless broadcasting for individuals and businesses. The main objective of this research is to verify an Electric Magnetic field (EMF) which is associated with Internet broadcasting from internet towers that do not exceed international standards. Therefore, Internet Broadcasting does not have negative effects on human health specifically to those who lived near the towers.
Return migration and self-employment: is there a ‘jack-of-all-trades’ effect?

With reference to Lazear’s Jack-of-all-Trades Hypothesis, I examine whether migrants are more likely to choose self-employment upon return because of the diverse work experience they gained abroad. The endogeneity between migration, human capital investment and self-employment is addressed by exploiting plausibly exogenous cohort and regional variation in the decision to migrate in the context of Egypt, retrospective and parental labor market information. Return migrants’ higher propensity to be and to generate jobs as self-employed is shown to proceed from participating in significantly more occupations over their work history than non-migrants. In line with Lazear’s framework, estimates confirm that entrepreneurship can be learned, and that exposure to multiple occupations matters for being and creating jobs as self-employed.

Intergovernmental cooperation in a dynamic environment : An analysis of the development of intergovernmental agreements and its explanations in subnational Switzerland

In 2008, the Neugestaltung des Finanzausgleichs und der Aufgabenteilung zwischen Bund und Kantonen (NFA) took effect and through it Switzerland’s intercantonal cooperation was strengthened in selected policy areas. The corresponding revised articles of the constitution even stipulate federal instruments to force cantons to enter into intercantonal agreements. While the new provisions can be judged as safeguards against national centralization, especially cantonal legislatures periodically expressed serious reservations about a further empowerment of institutions of horizontal resp. executive federalism. Two questions are crucial in this debate: Has the reform really resulted in a denser net of intercantonal agreements? And if so, how did the cantonal legislatures react to the increased institutionalization and importance of the socalled concordats? The paper is able to answer the first question by investigating the development of intercantonal agreements in Switzerland, especially for the recent period since the NFA took effect. It is further able to draw deeper insights into the working of intercantonal contractual cooperation. Thereby, updated data on the intensity of intercantonal cooperation is presented and analyzed. Two major findings result: The NFA did not result in an increase of intercantonal agreements, and intercantonal contracting is mainly driven by functional and only subordinately by political-institutional and partisan factors. The paper will close with an outlook on how to tackle the second question concerning the reaction of the cantonal legislatures to the NFA, i.e. its mere “threat” of further intercantonalization as well as its actual entry into force.
News and Investor Sentiments: The Impact on Trading Behavior

This study examines and compares the sentiment effect driven by trading and news information on market returns and volatility, as well as the applicability of news sentiment in portfolio construction. This article employs linguistic analysis to construct the market aggregate news sentiment index (MANSI), drawn from daily financial news about Taiwan listed firms, and we form the investor sentiment index (SI) by following Baker and Wurgler (2006). The evidence shows that MANSI has a stronger influence on market trading behavior than investor sentiment. The results also reveal that the news sentiment effect is more profound during market expansion periods, consistent with the findings in Chung, Hung and Yeh (2012) and Stambaugh, Yu and Yuan (2012). The cross-sectional portfolio analyses suggest that conditional on the lower news sentiment, smaller, more volatile and less profitable stocks generate higher returns. In addition, we develop long-short portfolios on the basis of size, volatility, and profitability and show that the previous MANSI state is a significant determinant of portfolio returns. In addition, MANSI has more influence on the trading behavior of foreign institutional investors and dealers, while investor sentiment reveals a stronger influence on domestic institutional traders. The results suggest that news sentiment can be an effective proxy for market returns and volatility and can be applied in portfolio construction.
Arab Israeli Teachers Working in Jewish Schools and Jewish Teachers Working in Arab Israeli Schools

In Israel, there is a separation between the Jewish education system and the Arab Israeli education system. The decision for this separation has both practical and ideological explanations. There are those who claim that the demographic realities dictate this separation. However it is revealing that the policy since the founding of the state was to strengthen and preserve the Jewish identity amongst the Jewish sector, and a coming to terms with the national identity of the Arab Israeli pupils. The ideological component is the more important of the two; this is evidenced by the fact that even in places where it would be possible to establish a combined education system, like in mixed cities (Tel Aviv-Yaffo, Haifa, Jerusalem, Acco, Lod, and Ramla), there is a complete separation between the two systems. This separation exists in every part of the education system although it is the most severe in the State-religious and Haredi education. There it is backed by instructions at the highest level that “advise” in no uncertain terms against the hiring of Arab Israeli teachers. This reality has many implications both on the educational level and on the overall societal level. On the educational level, it intensifies the fluctuations in supply and demand for teachers due to the limitations it creates in moving from sector to sector. On the
COMPARATIVE PRE-WEANING PERFORMANCE OF 75 % LARGE WHITE YORKSHIRE CROSSBRED PIGS OF FIFTH AND SIXTH FILIAL GENERATION

The overall birth weight of fifth and sixth filial generations of 75% Large White Yorkshire crossbred were 1.14 ± 0.02 and 1.22 ± 0.02 kg respectively. The birth weight of male and female pigs of fifth generations were 1.15 ± 0.02 and 1.13 ± 0.02 kg and sixth generations were 1.24 ± 0.03 and 1.19 ± 0.02 kg respectively. The weaning weight of overall, male and female piglets at 42 days of age for the fifth were 7.52 ± 0.15, 7.34 ± 0.19 and 7.72 ± 0.24 kg and sixth generation were 8.25 ± 0.20 kg, 8.08 ± 0.28 kg and 8.36 ± 0.31 kg, respectively. The pre-weaning weight gain of overall, male and female piglets up to 42 days of age for the fifth generation were 151.53 ± 3.43, 147.58 ± 4.39 and 156.89 ± 5.47 g/day and sixth generation were 169.08 ± 4.56, 164.85 ± 6.01 and 173.58 ± 6.91 g/day, respectively. There was 7.02%, 9.71 % and 11.58% improvement in overall birth weight, weaning weight and pre-weaning growth rate of sixth generation compared to fifth generation. Sex had significant effect on weaning weight and pre-weaning weight gain but had no influence on birth weight of piglets.
Analyzing Tobacco , Alcohol , and Substance Use among Kurdish Adolescents in South Eastern Turkey : A Test of Hirschi ’ s Social Bonding Theory

The proposed study contributes to our understanding of social bonding theory’s explanatory power among Kurdish teenagers by focusing on its applications in a non-western, Turkish Islamic society. There is no literature testing the relationship between social bonding theory and delinquency among Kurdish teenagers. Involvement in minor delinquency is dependent variable for this research project. Findings suggest a strong relationship between the Gülen movement and Kurdish adolescents’ probability of involvement in minor delinquent activities. Several directions for future research on Hirschi’s social bonding theory are recommended and some implications are drawn for deterring Kurdish adolescents from becoming involved in delinquent actions.
Using Experience Sampling Methodology to Advance Entrepreneurship Theory and Research

The authors propose the use of experience sampling methodology (ESM) as an innovative methodological approach to address critical questions in entrepreneurship research. ESM requires participants to provide reports of their thoughts, feelings, and behaviors at multiple times across situations as they happen in the natural environment. Thus, ESM allows researchers to capture dynamic person-by-situation interactions as well as between- and within-person processes, improve the ecological validity of results, and minimize retrospective biases. The authors provide a step-by-step description of how to design and implement ESM studies beginning with research design and ending with data analysis, and including issues of implementation such as time and resources needed, participant recruitment and orientation, signaling procedures, and the use of computerized devices and wireless technologies. The authors also describe a cell phone ESM protocol that enables researchers to monitor and interact with participants in real time, reduces costs, expedites data entry, and increases convenience. Finally, the authors discuss implications of ESMbased research for entrepreneurs, business incubators, and entrepreneurship educators.
The Rate of Crater Degradation and Topographic Evolution on the Moon: Results from the Maria and Initial Comparisons with the Highlands

Impact cratering dominates the landscape evolution of the Moon since the emplacement of the maria, with new craters being created and subsequently degraded by smaller impactors. New topographic measurements of the Moon in the last decade using laser altimetry (LOLA) and stereo photogrammetry (LROC and the Kaguya TC) enable improved characterization of how craters and other landforms evolve. The degradation state of craters is particularly useful for quantitatively assessing how quickly the lunar surface changes because craters have a regular and characteristic initial morphometry and form randomly in space and time.
PREDICTORS WITH SENSITIVE SUBSPACE ROBUSTNESS By

We consider an approach to training machine learning systems that are fair in the sense that their performance is invariant under certain perturbations to the features. For example, the performance of a resume screening system should be invariant under changes to the name of the applicant or switching the gender pronouns. We connect this intuitive notion of algorithmic fairness to individual fairness and study how to certify ML algorithms as algorithmically fair. We also demonstrate the effectiveness of our approach on three machine learning tasks that are susceptible to gender and racial biases.
WHAT ABOUT YOU ? THE CROSS-LEVEL IMPACT OF EMPLOYEE LOYALTY AND PERFORMANCE ON STUDENT

The purpose of this study is to examine links between, on the one hand, employee satisfaction, loyalty and performance, and on the other, the relationship between customer satisfaction and loyalty, as well as their inter-relationship. We conducted a study with employees (53 employees) and students (262 students) across seven departments of a private university in a developing European country. In order to test the cross-level effects of employee-level constructs on student-level constructs, a multilevel analysis was conducted using hierarchical linear modeling. The results confirmed the positive effect of employee satisfaction on employee loyalty and employee performance, but not the impact of the employees’ loyalty on their performances. At the same time, the results showed that students’ satisfaction was positively related to loyalty. Finally, the results showed that, unlike employee performance, employee loyalty at the level of the department had a positive and significant impact on the students’ loyalty and also enhanced the effect of students’ satisfaction
Spring 4-20-2018 Summer Camp as a Force for 21 st Century Learning : Exploring Divergent Thinking and Activity Selection in a Residential Camp Setting

This study investigated change in divergent thinking (DT), an indicator of creative potential, at 2 genderspecific residential summer camps. Additionally, this study examined whether the change in DT varied by gender and by the type of activities campers self-select. Quantitative methods, using a quasiexperimental design was used in order to understand differences in camper scores. A total of 189 youth, 100 girls, 89 boys, between the ages of 9 and 14 years participated in the current study. Participants were administered a modified version of Guilford's (1967) alternate uses task, a measure of DT, in which respondents were asked questions such as name all of the uses for a brick or name all of the uses for a plate before the camp session started, and then again at the end of the two-week session. Results indicate overall mean significant increases in DT across all scoring methods of fluency, flexibility, and originality. Participants who self-selected 1 or more artistic activities (e.g., drama, arts and crafts, dance) had significant increases on the tasks as opposed to participants who did not select any artistic activities (e.g., basketball, baseball, archery). Finally, girls significantly increased across all scoring methods, whereas boys slightly increased in fluency and flexibility but not in originality. These results indicate residential summer camp may provide a creativity “benefit” for youth in attendance, especially those who participate in certain activities. Practitioners should use this study to understand their own programming in terms of creativity, activity offerings, and camp culture.

Health Promotion program to Improve the Lifestyle of School Children Living in Slum Areas in Helwan Governorate 1

The school years are a time when the foundations of a healthy lifestyle are formed and when health promotion programs are likely to have the greatest impact. The aim of this study was to evaluate the effect of health promotion program on improving lifestyle of school children living in slum areas. Design: A quasi –experimental design was used. Setting: The study was conducted at two governmental primary schools in Azbat Elwalda, in Helwan Governorate Sample: A stratified multi-stage cluster random sample was used for selection of school children in slum areas ,the total number of governmental primary schools in Azbat Elwalda are ( 3 ),two were chosen randomly. One class from fifth grade and one from sixth grade were selected randomly from each school. The total number of children for two schools were 200 (both sexes). Tools: 3 tools were used 1) A structured interviewing questionnaire was used to assess students socio-demographic characteristics, students' perception of social and physical environment of school, students’ common health problems during the past two years and students’ knowledge about healthy life style . These tools were used before and after program. 2) A physical examination to assess the student from head to toe. 3) An observational checklist for assessing in and out school's environment. Results: the study confirms that diseases of respiratory system had the highest frequencies among the students as follows: less than two fifths for common cold, more than one third for tonsillitis and bronchitis and more than one quarter for influenza. There was difference between before and after program implementation concerning students’ health promoting life style, perception of social and physical school environment. The differences were statistically significant for all of variables (P = < 0.001). Conclusion: The study concluded that students perception improved toward their social, physical school environment and their knowledge about healthy life style after implementing the health promotion program . This improvement was proved statistically . Recommendations : The study recommended that a health promotion program are strongly needed to school children to improve their lifestyle especially school children living in slum areas and the necessity of improving school environmental sanitation for the promotion of students health.
