Early Degradation

Acid rain as an important environmental issue has negative impact on bitumen performance, thereby shortening the service life of bituminous pavements. Rapid industrial and economic developments causes negative changes in the environment, including acid rain. Acid rain consisting of sulphuric acid and nitric acid has adverse effects on bituminous pavements. Both these acids react with the bitumen and adversely effect’s the properties of the bitumen leading to degradation of pavements at early stage of life. Early degradation of such pavements can be reduced to some extent by using waste plastic in bituminous surface course. Besides acid rain puts an adverse effect on the properties of bitumen, it also percolates deep down in the various down layers of pavements and reduces the serviceability of our pavements & its foundation. Waste plastic such as PET water bottles cannot only prevents the early degradation of pavements but also can prevents entry of acid rain into deep down layers of pavement as it absorbs acid rain water which makes it hydroscopic as because of it acid rain water does not percolate deep down into below pavement layers. In this paper, interaction between constituents of acid rain and bitumen is being investigated by analyzing the effect of sulphuric acid and nitric acid on control mix (mix without plastic content) & 6% WPET mix (mix with 6% waste plastic PET content) by using Marshal stability test. Also, it’s evaluated how improvement in bituminous surface course can be done by using waste plastic on acid rain area’s so that our pavements show good safety & serviceability.

This research to analyze the impact of closure policy Teleju brothel by Pekanbaru govermentin 2010. Guidelines for works are Pekanbaru Local Regulations No. 12 of 2008 on Social Order-liness. Closure this brothel inflicts positive and negative impact for society.The research wasconducted to obtain early stage formula for the government to take action against the prostitu-tion activities. This research uses policy research approach with a qualitative method, becausein prostitution activities and prohibition by goverment is an assessment that needs to be done byanalyzing documents and unstructured interview.The results showed that after the closing of the Teleju brothel have an impact on the deploy-ment of a prostitution and affect the economy of the surrounding residents. Government seeksto tackle prostitution in Pekanbaru by moving the brothel, conduct regular raids and providetraining. The effort is considered to be less than the maximum because the handling is not basedon the root of the problem and not programmed properly. There are several causes of failure ofgovernment to overcome the prostitution problem in Pekanbaru, including: policy content isless focus on the prostitution problem, the government did not proceeds with data, lack of finan-cial support, contra productive programs between local government with the police and TNI,and the policy object is difficult to be given understanding.

This study was based on the findings during teaching and learning process at FKIP Universitas Dehasen Bengkulu (the Faculty of Educational Science and Teacher Training of Dehasen University of Bengkulu). There was a phenomenon of declining of good character value and morality. This is because of the misused of advancing technology by students that brings negative impact on the students' character and morality. This phenomenon was especially found among new students of FKIP (Faculty of Educational Science and Teacher Training) on their early stage of study. At the meeting of Educational Profession (Profesi Pendidikan) course, we did early observation by making contract with the new student.. They generally still brought their local character and moralor their old behavior. This could be seen, for example, they talked to their lecturers and seniors impolitely or often used their local language.  Everyone's patience was needed in dealing withthis phenomenon. As the lectures progressed, especially Educational Profession course, we tried to internalize character values toward the students. This had positive impact for them. Today, they are found to be more polite, for example, they greet their lecturers and seniors when they meet them. This study dealt with character values such as: religious, discipline, honest, hard work, responsible, love peace, appreciate achievements, and friendly or communicative. This Exploratory study which was done to internalize character value of the students, has positive impact, this can be seen fromthepositive progress of students' character. Students who already have good character will keep learning to have better personality. This wil affect their future job, especially if they become teachers.

Nitration of biodiesel from Jatropha curcas oil using mixture of HNO3 and H2SO4 had been done in an attempt to obtain a cetane improver or cetane number enhancer. The nitration was carried out by varying the numbers of moles of sulphuric acid, nitric acid, temperature and time. The process was conducted in a round bottom flask reactor that equipped with a magnetic stirrer and a ball cooler on a water batch. The mixture of H2SO4 and HNO3 was placed in the reactor and subsequently added slowly with biodiesel drop by drop. The results showed that increasing the mole numbers of sulphuric acid tends to reduce the yield or volume and total N of nitrated biodiesel. Increasing the number of moles of nitric acid tends to increase the yield, but decrease the value of total N. While increasing of temperature and reaction time tends to reduce the yield and total N. From FTIR spectra product was estimated as a mixture of esters of alkyl nitrates and nitro. From the testing of cetane number it can be predicted that nitrated biodiesel potentially as cetane improver.

Accreditation Standards

Purpose – The purpose of this paper is to contribute to the debate on the quality and accreditation of management education by examining the fit between the characteristics of current management academics in Portugal and recognised accreditation standards. For purposes of comparison, the authors use both general Portuguese teaching accreditation standards and specific international standards for management education. Design/methodology/approach – The authors analyse indicators of staff career positioning, tenure status, full time vs part-time, age, degree qualifications, field of training, level of academic inbreeding, internationalisation, research activity, professional activity, and the number of hours taught per week. The authors also examine the relationship between them, in light of accreditation standards, for all academic staff teaching in management degrees submitted for compulsory accreditation by the Portuguese accreditation agency. Findings – The reality found in this study shows gaps between the actual attributes of management academics and what can be considered appropriate attributes, according to the general consensus found in the literature and which is duly mirrored in common “qualified faculties” accreditation standards by Portuguese and international standards (AACSB, AMBA and EQUIS). Research limitations/implications – The findings relate to the Portuguese situation and the analysis developed should be extended to other contexts. Also, while the data, which were collected through a census, has a wide national scope, it only covers one academic year. Practical implications – This work has policy setting implications for degree accreditation and for developing capacity during the transitional periods when universities implement the mandatory minimum standards. It can also help universities to benchmark themselves against their peers as a diagnostic tool for elaborating improvement plans. Social implications – The massification of higher education has led to legitimate concerns about the quality of the services provided, and consequently accreditation procedures were devised to restore trust. However, policy makers must be aware of the impacts of their actions, namely the effects of degree accreditation, as their goals need to be achieved with the minimum negative impact on academic work. Originality/value – The authors work sheds light on the characteristics of those who teach management and how they align with the current accreditation policies that affect academia globally and, in the process, presents empirical evidence from Portugal, which is at a relatively early stage in the accreditation process.

This study analyzes the performance of a credit-based mobility management scheme considering travelers’ budgeting behaviors for credit consumption under uncertainty. In the scheme, government agencies periodically distribute a certain number of credits to travelers; travelers must pay a credit charge for driving to complete their trips. Otherwise, they can take public transit free of credit charge. Consequently, within a credit-releasing cycle, travelers must budget their credit consumption to fulfill their mobility needs. Such budgeting behaviors can be viewed as a multistage decision-making process under uncertainty. Considering a transportation system with a credit scheme, we propose parsimonious models to investigate how the uncertainty associated with individual mobility needs and the subsequent travelers’ credit-budgeting behavior influence the multistage equilibrium of the transportation system, as well as the performance of the credit scheme on managing the transportation system. Both analytical and numerical results suggest that travelers tend to restrict their credit consumption in the early stage of a credit-releasing cycle to hedge against the risks associated with using up all credits, which compromises the performances of credit-based schemes. Moreover, a negative attitude toward risk aggravates the discrepancy between the credit consumption of the early and late stages. Last, we propose a contingency credit scheme to mitigate the negative impact incurred by travelers’ budgeting behaviors.
