Actuarial evaluation of government of Punjab pension fund liabilities

Mestrado em Actuarial ScienceO Governo de Punjab (GoPb) organizou um plano de pensões de benefícios definidos para os seus funcionários permanentes. Além de atender aos pagamentos anuais dos benefícios de pensão, o GoPb contribui igualmente para um fundo de reserva designado Punjab Pension Fund (PPF). O Punjab Pension Fund foi estabelecido ao abrigo da lei designada Punjab Pension Fund Act 2007. A principal função do PPF é gerir os fundos disponibilizados pelo GoPb para atender às responsabilidades com pensões dos seus funcionários. Este trabalho tem por finalidade essencial fazer uma análise dos aspetos mais significativos do PPF, dada a importância que este fundo tem para o Governo da província, atualmente e no futuro. Detalhando um pouco mais, pode dizer-se que o trabalho foi desenvolvido com base nos seguintes objetivos: i. Realizar uma avaliação atuarial do Fundo de Pensões do Governo de Punjab; ii. Realizar projeções de fluxo de caixa do Fundo de Pensões do Governo de Punjab nos próximos cinco anos; iii. Fazer recomendações relativamente aos requisitos de financiamento para o Fundo de Pensões, com base nos resultados obtidos em i. e ii.; iv. Realizar uma análise de sensibilidade das principais premissas com efeitos sobre as projeções das responsabilidades com pensões e demais fluxos financeiros; v. Identificar as medidas reformadoras que permitam colocar a taxa de contribuição do plano de pensão existente a um nível aceitável; vi. Propor a estrutura de um novo plano de pensão, destinado aos futuros contratados.This actuarial investigation carried out of the Government of Punjab Pension Scheme liabilities as at the valuation date. To summarize, the work was developed with the following main objectives: i. Conduct an actuarial valuation of Punjab Government Pension Fund; ii. Carry out cash flow projections of Punjab Pension Fund over the next 5 years; iii. Make recommendations for funding requirements for Pension Fund based upon above findings; iv. Carry out sensitivity analysis of key assumptions on pension liability and cash flow projections; v. Identifying reform contours to bring contribution rate of the existing pension scheme at a manageable level; vi. Propose a structure for a new pension scheme for new hires.info:eu-repo/semantics/publishedVersio

Antecedents of job satisfaction: A study of telecom sector

This study is based on the assumption that “a happy worker is a productive workerâ€. The research was conducted to identify the significance of those factors that lead towards job satisfaction and commitment of employees working in the telecom sector of Pakistan. The associations among pay and benefits, performance appraisal system, career development and management, supervision and collegiality and open communication (independent variables) were investigated with job satisfaction (dependent variable). The relationship between job satisfaction (dependent variable) and job commitment (outcome) was also hypothesized. Through questionnaire survey responses from 221 employees working at managerial and non-managerial positions were collected, which showed the significant association of supervision and collegiality and open communication on job satisfaction. Furthermore, job satisfaction was also found highly correlated and dependent upon job commitment. Managerial implications and conclusions are presented based upon these results.Labor and Human Capital,

Helping children to understand particulate nature of matter

Whenever I taught about the particulate nature of matter in solids, liquids and gases, I often had difficulty explaining this abstract concept to my students. The students, in turn, had much difficulty conceptualizing the structure and behavior of the particles, which ultimately led to difficulties in understanding the complex configuration of particles in matter at various levels. This article focuses on studies that reveal students’ alternative frameworks for the particulate nature of matter in solids, liquids and gases. Also, I suggest factors that contribute to these alternative frameworks, incorporating my own experiences in developing an understanding of this concept. Finally, in light of these alternative conceptions and difficulties, I consider strategies for effectively teaching this abstract concept

An application of control charts in manufacturing industry

The range control chart and the X bar control chart are the well known and the most popular tools for detecting out- of-control signals in the Statistical Quality Control (SQC). The control charts has shown his worth in the manufacturing industry. In this study we have applied the range and the X bar control charts to a product of Swat Pharmaceutical Company. The variables under study were weight/ml, Ph, Citrate % and the amount of fill. Besides the X bar control chart, the exponentially weighted moving average control chart and the multivariate Hotelling's T2 control chart were applied to the same data

Equivalent Binary Quadratic Form and the Extended Modular Group

Extended modular group $\bar{\Pi}=$, where R:z\rightarrow -\bar{z}, \sim T:z\rightarrow\frac{-1}{z},\simU:z\rightarrow\frac{-1}{z +1} , has been used to study some properties of the binary quadratic forms whose base points lie in the point set fundamental region $F_{\bar{\Pi}}$ (See \cite{Tekcan1, Flath}). In this paper we look at how base points have been used in the study of equivalent binary quadratic forms, and we prove that two positive definite forms are equivalent if and only if the base point of one form is mapped onto the base point of the other form under the action of the extended modular group and any positive definite integral form can be transformed into the reduced form of the same discriminant under the action of the extended modular group and extend these results for the subset \QQ^*(\sqrt{-n}) of the imaginary quadratic field \QQ(\sqrt{-m}).Comment: Paper contains two figures and twelve page

Near-capacity iterative decoding of binary self-concatenated codes using soft decision demapping and 3-D EXIT charts

In this paper 3-D Extrinsic Information Transfer (EXIT) charts are used to design binary Self-Concatenated Convolutional Codes employing Iterative Decoding (SECCC-ID), exchanging extrinsic information with the soft-decision demapper to approach the channel capacity. Recursive Systematic Convolutional (RSC) codes are selected as constituent codes, an interleaver is used for randomising the extrinsic information exchange of the constituent codes, while a puncturer helps to increase the achievable bandwidth efficiency. The convergence behaviour of the decoder is analysed with the aid of bit-based 3-D EXIT charts, for accurately calculating the operating EbN0 threshold, especially when SP based soft demapper is employed. Finally, we propose an attractive system configuration, which is capable of operating within about 1 dB from the channel capacity
