Precipitation Variability and Probabilities of Extreme Events in the Eastern Mediterranean Region (Latakia Governorate-Syria as a Case Study)

This study aimed at analysis of the general-index change for the mean annual and seasonal precipitation in six stations in Latakia Governorate (Syria). The data of precipitation were collected for 40 consecutive years (1970–2010) in order to figure out the extent of the changes and variability in precipitation rates and the impact of this change on changes in the potential density that might cause extremely high or low precipitation rates according to Gumbel distribution of the extreme precipitation rates. Results revealed a decrease of the annual precipitation rates in all stations, the reduction in precipitation ranged from 46 to 210 mm during the whole period of the study. Spring, however, recorded the highest and statistically significant reduction, which reached 46–210 mm, while winter precipitation increased by 21–82 mm. Spring also has witnessed a decrease of about 3–9% of the total annual precipitation as compared to winter precipitation which increased by 5–8% of the total. The potential density of extremely high winter precipitation rates increased in all stations as indicated from Gumbel distribution in winter, and a greater increase took place in the probabilities of occurrence of the extremely low spring precipitation rates. This shows significant probability of occurrence of drought during spring season. By contrast, probabilities of winter precipitation rates increased more, thus winter is relatively more humid than before and spring is relatively drier than before.

PENGARUH BEBAN KERJA, KOMPETENSI SERTA KOMPENSASI TERHADAP PRESTASI KERJA KARYAWAN HOTEL EXCELTON PALEMBANG

This study aims to determine the Effect of Workload, Competence and Compensation on Employee Performance at Excelton Hotel Palembang. The data used in this study are primary and secondary data, with data collection techniques carried out through questionnaire distribution to 68 employees of the Excelton Hotel Palembang. The analysis technique used is multiple linear analysis techniques that are processed using the help of the computer program Statistics Product and Service Soulution (SPSS 22). From the results of the study there is a positive and significant influence of Workload, Competence and Compensation on Employee Performance at the Excelton Hotel Palembang, which is indicated by the Regression model = 38.016 + 0.850X1 + 0.427X2 + 0.657X3 + e. Simultaneous correlation between the Work Load independent variable (X1), Competency independent variable (X2), Compensation independent variable (X3) to Work Performance dependent variable (Y) equals 0.724 means that there is a strong and positive directional relationship. Partial correlation of Workload (X1) to Work Achievement (Y) equals 0.562 means that there is a fairly strong and positive relationship in the same direction, partial correlation of Competence (X2) to Work Achievement (Y) equals 0.581 means that there is a strong enough relationship and positive direction, partial correlation Compensation (X3) to Job Performance (Y) equals 0.613 means that there is a strong and positive directional relationship. This can be seen from the large coefficient of determination which is quite strong at 50.8% so there are still 49.8% of variables that cannot be examined. From the results of data conducted by researchers known Workload (X1), Competence (X2), Compensation (X3) significantly influence Work Performance (Y) of Excelton Hotel Palembang Employees with a calculated F value of 23,480 and a significant probability of 0.00 <0, 05. Workload (X1) has a significant effect on Work Performance (Y) with a calculated T value of 3.496 and a significant probability of 0.001 <0.05. Competence (X2) has a significant effect on Job Performance (Y) with a calculated T value of 2.033 and a significant probability of 0.04 <0.05. Compensation (X3) has a significant effect on Job Performance (Y) with a calculated T value of 2.776 and a significant probability of 0.007 <0.05.

Magnitude and nucleation time of the 2017 Pohang Earthquake point to its predictable artificial triggering

A damaging Mw5.5 earthquake occurred at Pohang, South Korea, in 2017, after stimulating an enhanced geothermal system by borehole fluid injections. The earthquake was likely triggered by these operations. Current approaches for predicting maximum induced earthquake magnitude ($${M}_{\max }$$ M max ) consider the volume of the injected fluid as the main controlling factor. However, these approaches are unsuccessful in predicting earthquakes, such as the Pohang one. Here we analyse the case histories of induced earthquakes, and find that $${M}_{\max }$$ M max scales with the logarithm of the elapsed time from the beginning of the fluid injection to the earthquake occurrence. This is also the case for the Pohang Earthquake. Its significant probability was predictable. These results validate an alternative to predicting $${M}_{\max }$$ M max . It is to monitor the exceedance probability of an assumed $${M}_{\max }$$ M max in real time by monitoring the seismogenic index, a quantity that characterizes the intensity of the fluid-induced seismicity per unit injected volume.

Probability of willingness to pay road pricing based on the perspective of households in Jakarta

The determination of tariff is necessary for a city willing to implement electronic road pricing such as Jakarta. Therefore, this study was conducted to investigate the effect of household characteristics on the willingness and probability to pay more than IDR 20,000. The focus was on those commuting to work within the city where the majority of people work in the formal sector. Moreover, the Willingness to Pay IDR 20,000 was proposed as a variable while age, number of family members, income, vehicle ownership and the work type were used as the explanatory variables. The results showed the general effect of households in receiving ERP rates was low as indicated by the 16.9% recorded. However, family with total members of 4-5 people and owning a vehicle was observed to have a partially great and significant probability to increase the willingness to pay tariffs > IDR 20,000 while those earning income <IDR 5 million and working as private employees were discovered to have contributed negatively and significantly even though the probability was small. There is, therefore, the need for a comprehensive study when determining tariffs and the amount is recommended to be more expensive than public transport.

Probabilistic analysis of the active earth pressure on earth retaining walls for c-ϕ soils according to the Mazindrani and Ganjali method

The determination of the earth pressure coefficients (K) in geotechnical engineering is one of the most critical procedures in designing earth retaining walls. However, most earth pressure theories are made for either clay or sands, where the c-ϕ soils are the least analysed. In this paper, an analysis of the earth pressure for drained mixed soils based in Mazindrani and Ganjali (J Geotech Geoenviron Eng 123:110–112, 1997) theory was carried out. Earth pressure coefficients are generally used in a deterministic way and can represent designs under an inadmissible risk. Therefore, Reliability-based design arises as an essential tool to deal with soil variability as one of the main aspects of the geotechnical uncertainties. The influence of the soil variability in the active earth pressure for a c-ϕ soil was performed through probabilistic analysis concerning the Ka coefficient of variation (Cv) of both shear strength parameters. The sensitivity analysis shows a Cv in which the cohesion begins to have a more significant correlation with Ka than the friction angle. The results show an increase of the statistical Ka concerning the deterministic value as the soil variability and the soil slope (β) increase. Although the statistical value does not increase significantly, a statistical analysis on gravity walls and sheet pile walls in c-ϕ soils shows a significant probability of failure (pf) increase. The pf obtained through the c-ϕ variability can be considered inadmissible even if the required FS are met.

Analysis of calculating level of service for pedestrians

In this paper, several methods of the assessment of pedestrian objects operation based on the level of service are reviewed. Today, there is a problem that should be assessed, particularly how pedestrian paths respond the level of service. Assessment of this level is the most widespread method of determination the objects` quality that relate to the pedestrian operations. Places, where a significant probability of conflict between different flows and their users, are often called intersections. Moreover, on such intersections, particularly with complex road conditions and on which the movement of cyclists, cars, and different vehicles is present, road users face with complicated situations when every of them should be sure in his safety and forecast further actions and decisions of other road users. The most widespread and generally accepted methods of assessment of level of service on pedestrian path, particularly: Highway capacity manual 2000 method, Australian method, method of the trip quality, Landice model and common approach analysis. Vehicles, signal delay, and interaction of pedestrians and cyclists were determined as the main factors that have impact on the level of service of pedestrians at the intersections. Analysis of different methods in the paper allows assessing and identifying the level of service determining the characteristics that could help in solving the questions concerning the comfort of pedestrian movement. In the range of these methods, the principles of vehicles movement and interaction with pedestrians are also reviewed. Other methods relate more to the design of the objects of pedestrian environment than factual movement of pedestrians. To form the whole understanding of the methodology of determination of the level of service of pedestrian objects, we should analyze and compare the values, obtained by different methods.

The Effect of Motivation, Work Ethos and Work Discipline on Teacher Work Productivity at Madrasah Ibtidaiyah Negeri (MIN) Binjai

Madrasah Ibtidaiyah (MI) is the most basic level educational institution which is a continuation of the Raudhatul Athfal (RA) or Kindergarten (TK) level in formal education in Indonesia, which is managed by the Ministry of Religion. The problem is whether partially and simultaneously Motivation, Work Ethic and Work Discipline on Teacher Work Productivity. The technique in the research was carried out by means of a questionnaire by distributing a list of questions to respondents as many as 40 teachers. The research shows that the Fcount value is 544.007 with a significant level of 0.00. Because Fcount 544.007> Ftable 2.87 and the significant probability is much smaller than 0.05, namely 0.00 t table 1.688 with a significant 0.046 < 0.05, meaning that partially there is a positive and significant effect of Work Motivation on Work Productivity. The results of the work ethic variable test, the value of tcount -3.848 < t table 1.688 with a significant 0.000> 0.05, meaning that it is partially influential but not significant on work ethics on work productivity. The result of the work discipline variable test, tcount 4,912 > t table 1,688 with a significant 0,000 > 0.05, meaning that partially there is a positive and significant influence of Work Discipline on Work Productivity. While the adjusted R square is 0.977, this means that 97.8% of the variation in Work Productivity can be explained by the independent variable Work Motivation, Work Ethic, Work Discipline, while the rest (100% - 97.7% = 2.3%) can be explained by other independent variables.
