The paper aims to explore the long-term prospects of mobile broadband adoption in a developing country. The supply-side and demand-side policy measures are recommended to counter the challenges to broadband adoption.

Methodologically, this study uses document analysis to explain secondary data including growth statistics, trade literature and previous scholarly research. Based on the growth statistics of broadband and the informed market insights, the research discusses the prevailing market threats and recommends counter measures to improve the long-term prospects of broadband propagation.

The growth of mobile broadband is settling down in Pakistan due to various barriers like cost, literacy, security and unavailability of local content. Collaborative efforts are required by the government, the service providers and the people to enhance the adoption of broadband service and secure economic benefits of the broadband.

The research offers useful implications for managers and policymakers in Asian and African developing countries; the policy measures discussed here may serve as guidelines for them in the design of their own policies regarding broadband supply and demand.

The study makes an effort to examine the broadband growth in a developing country on the basis of both quantitative and qualitative aspects. The research endeavors to fill the gap on the particular scholarship of research covering potential uptake of broadband services and the effects of constraining elements to broadband adoption in a developing country.

This paper aims to present a technique that has been developed to study the wear in the camshaft and tappet. The engine manufacturers use the most suitable materials, lubrication additives and surface coatings to minimize friction in all the components of the engine. Reduced friction results in less wear of critical engine components. The researchers are constantly trying to find an improved lubrication formula which reduces the wear and friction coefficient at a considerably low price. In this regard, the cam follower interface is of much importance because most of the wear occurs in this interface.

The tappets and the cam lobes are analyzed to determine wear. A two-dimensional optical surface profilometer is used to measure the tappet wear, and a high-resolution linear variable differential transformer is used for the measurement of cam lobes. Tests are conducted on Mercedes Benz engine OM 646 under constant camshaft speed, constant inlet lubricant temperature and constant lubricant pressure to study the oil rheology on cam tappet wear.

The results show that the wear occurs on the cam tappet interface, which is almost a linear phenomenon, and it increases with use.

Customized jigs were made to measure wear of camshaft and tappet.

Spatio-temporal variations in precipitation pattern of district Sargodha is one of the most significant researchable questions because of the massive reliance on rainfall for agricultural practice in the study area. The pattern of current rainfall in the study area is unexpectedly changed. The purpose of the present study is to examine the changing precipitation pattern and to link it with climate change.

The study was conducted by using rainfall data of the past 30 years collected from 8 meteorological stations around the study area. The averages of rainfall on monthly basis were temporally arranged, and the fluctuation trends were studied using GIS and statistics. The temporal data of rainfall were compared and contrasted with the precipitation normals of the study area from 1981to 2010. The rainfall deviation in the present study was calculated. The spatial pattern of rainfall was plotted by interpolating the eight points of Punjab around the study area for the first two decades, whereas the past decade was analysed by incorporating five more points of Tehsils in the existing eight. The spatial and statistical representation of data were examined by compare and contrast with the previous findings.

The rainfall in the study area showed remarkable changes in magnitude and spatiality. The rainfall in the district is on the rise, whereas the spatial pattern of rainfall is becoming more complex and anomalous in character. This paper provides convincing evidence about the impact of climate change on the magnitude and spatial patterns of precipitation in the study area.

It will be helpful for understanding the shifts in the rainfall pattern in future as well as for the preparation of response to the issue of climate change and its impacts.

The current manuscript, for the very first time, provided detailed insights about the precipitation pattern shifting during the last 30 years in district Sargodha, Punjab, Pakistan. Furthermore, agricultural sector would likely get severally affected because of seasonal changes in climatic factors like rainfall and have strong food security implications. The current findings will be useful to manage the climate change-related issues in Pakistan and helpful for the policy makers to design a coping strategy for climate change impacts.

Gridded management in the public service supply is still in the experience exploratory stage, and this paper aims to analyze the inherent logic and operation mode of the gridding mechanism of the public supply based on the existing theory study and practices, and verify its efficiency so as to come to the conclusion whether it could be promoted to a wider range.

The methodology applied in this paper was case study/deductive induction.

The grid model in the public service supply needs to be demonstrated completely in theoretical logic and operation principles before it is promoted across the country. Meanwhile, full support of the government is required in terms of service concept, function distribution, technical parameters and infrastructure.

The inherent logic and operation mode of the gridding mechanism of the public service supply needs enough practice tests. The practical test of efficiency analysis of the gridding mechanism of the public service supply is not enough.

This paper validated whether the gridding mechanism that originated from China’s urban management can be promoted to all over the country in the public service supply. It provides references for government policy.

This paper constructs a gridded management model for public service provision in urban and rural areas on the basis of an analysis of the plight of traditional model of public service provision, thus delivering the same standard of public service for both urban and rural areas through optimization of resource allocation without requiring more supply and fundamental change to the content of service.

This paper aims to develop a fuzzy logic-based algorithm to predict the intermetallic compound (IMC) size and mechanical properties of soldering material, Sn96.5-Ag3.0-Cu0.5 (SAC305) alloy, at different levels of temperature. The reliability of solder joint in materials selection is critical in terms of temperature, mechanical properties and environmental aspects. Owing to a wide range of soldering materials available, the selection space finds a fuzzy characteristic.

The developed algorithm takes thermal aging temperature for SAC305 alloy as input and converts it into fuzzy domain. These fuzzified values are then subjected to a fuzzy rule base, where a set of rules determines the IMC size and mechanical properties, such as yield strength (YS) and ultimate tensile strength (UTS) of SAC305 alloy. The algorithm is successfully simulated for various input thermal aging temperatures. To analyze and validate the developed algorithm, an SAC305 lead (Pb)-free solder alloy is developed and thermally aged at 40, 60 and 100°C temperature.

The experimental results indicate an average IMCs size of 5.967 (in Pixels), 19.850 N/mm² YS and 22.740 N/mm² UTS for SAC305 alloy when thermally aged at an elevated temperature of 140°C. In comparison, the simulation results predicted 5.895 (in Pixels) average IMCs size, 19.875 N/mm² YS and 22.480 N/mm² UTS for SAC305 alloy at 140°C thermally aged temperature.

From the experimental and simulated results, it is evident that the fuzzy-based developed algorithm can be used effectively to predict the IMCs size and mechanical properties of SAC305 at various aging temperatures, for the first time.

Acceptance and use of mobile shopping as the preferred shopping medium is becoming the new normal today. The proliferation of mobile shopping practices follows unsteady growth patterns in different countries. Despite challenges of price, quality and privacy matters, young consumers still lead the race to engage in mobile shopping activity in developing countries. This research investigates the determinants that either support or hinder the mobile shopping intentions of aspirant young consumers in Pakistan.

The present research applies a consumer-centric approach to the technology adoption framework to unearth the behavioral patterns of these young consumers in Pakistan. Employing the structural equation modeling technique, this research examines the significant effect of structural assurance, perceived risk, trust and various unified theory of acceptance and use of technology (UTAUT) model constructs on behavioral intention to engage in mobile shopping.

This research examines the significant effect of structural assurance, perceived risk, trust and various UTAUT model constructs on behavioral intention to engage in mobile shopping. Results also demonstrate a significant moderating effect of structural assurance and prior shopping experience on the relationship between perceived risk, trust and mobile shopping intentions. Further, the mobile shopping patterns for the male and female segment indicate a significant difference for perceived risk, trust structural assurance and social influence. The research contributes to the growing body of knowledge which advocates the application of consumer-centric customized model approach to explore various factors that either facilitate or impede the adoption of mobile shopping in a developing economy.

The study validates the need to enforce structural assurance mechanism for facilitating mobile shopping in a developing country. It also offers practical implications for online businesses and marketers striving to attract and retain more mobile customers.

The study offers practical implications for online businesses and marketers striving to attract and retain more mobile customers.

This study offers fresh insights about driving elements and impediments of mobile shopping behavioral intentions. Structural assurance and prior shopping experience appear to influence the mobile shopping behavior through direct and indirect effect.

This study aims to develop a Sharīʿah-compliance rating mechanism for the Islamic financial services industry (IFSI), with a special focus on banking. The banking sector is taken as the area of focus due to its leadership role in the volume of global Sharīʿah-compliant assets.

The objectives of the Islamic financial system (IFS) are selected as the basis for ratings. A range of performance indicators (leading to achievement of the objectives) is grouped into four broader categories and used in the study to allocate scores with a sum total of 100. Special considerations – including the amount of resources required in performing an activity, suitability of prevailing business conditions, the degree of compulsion/discretion in performing a task and linkage with the essence of the IFS – were taken into account in the allocation of scores.

This study groups multiple performance measures into four categories, including portfolio construction (deposits mechanism, participatory and asset-based modes of financing), access to finance (service to the less-privileged and sector screening), reputation (disclosures and stakeholders’ survey) and Sharīʿah governance (Sharīʿah supervision and controls, charitable operations, human resources, product development and organization). The Portfolio, Audit, Reputation and System (PARS) rating system is then developed.

A Sharīʿah-compliance rating system is helpful in measuring the progress towards goal achievement of the IFS and in gaining stakeholders’ trust. It is also important for Sharīʿah boards and regulators in policy formulation, for management in addressing weaknesses and taking corrective measures and potentially for standard-setting bodies.

This study presents a comprehensive quantitative Sharīʿah-compliance rating mechanism, taking into consideration the objectives of the IFS – equitable distribution of wealth and financial stability, in addition to Sharīʿah-compliance in operations. Development of Sharīʿah-compliance quality ratings for Islamic banking is essential to gain customers’ trust; the suggested methodology is thus a contribution to the literature on Islamic finance.

The purpose of this paper is to present an analysis of current practices of Islamic mortgages in the light of the principles of Islamic financial system, to document divergences – if any. A subsidiary goal is to develop an Islamic Mortgage Model (IMM) based on Musharakah principles.

The author documents theoretical underpinnings of risk-return sharing from the Shari’ah perspective. A comparative study of conventional and Islamic mortgages is completed; existing practice of Islamic mortgages analyzed in the light of Musharakah principles and divergences identified. IMM is developed after taking divergences and Musharakah principles into considerations. A housing case is used to highlight differences (in financial terms) under multiple methods and scenarios.

Study documents multiple divergences from Musharakah principles in the existing practice of Islamic mortgages including ignorance of market pricing in the negotiation of rentals and trading of equity units, and transfer of all ownership risks and rewards (vacancy, damage, destruction and market) to one partner (i.e. customer). Practice is divergent from principles in the area of economic substance. Modified IMM is developed by taking into account Musharakah principles; and differences highlighted by calculating financial figures – to determine financial rights and liabilities of the parties.

Divergence from the principles of risk-return sharing leads to failure in the achievement of Islamic finance objective of equitable distribution of wealth. Moreover, protection of capital for financier reduces the market abilities to achieve financial stability by matching credit expansion with the rise in the real economy. Shari’ah boards and regulators, as well as, management of Islamic banking industry are expected to incorporate proposed changes in-practice for the realization of Islamic finance objectives.

This study contributes to Islamic finance literature in the area of risk-return sharing. Based on important objectives of Islamic finance – equitable distribution of wealth and financial stability – divergences identified and a modified IMM in the light of Musharakah principles is presented. Descriptive rules are transformed into financial figures to document financial rights and liabilities of the concerned parties.

This study aims to evaluate the role of the prevailing currency systems in achieving (or departing from) the socio-economic objectives of a progressive and just society; i.e. featuring stability and equitable distribution of wealth.

After documenting historical developments in currency systems, the study reviews the Islamic perspective on the matter. Features of an ideal currency system are listed and then a critical evaluation of existing currency systems – fiat, banking and cryptocurrency – is undertaken.

It is found that existing currency systems – fiat, banking and cryptocurrency – are not compatible with the socio-economic objectives of a forward-looking, progressive society, which upholds transparency and justice as its core values. The study documents that Sharīʿah norms have no preference or dislike for any of the existing currency systems. Any prudent currency system compatible with the objectives of the Islamic financial system (i.e. stability and equitable distribution of wealth) is acceptable. A single international reserve currency (with country-specific legal tendering) is subject to the risk of destabilisation across global markets.

This paper recommends autonomy of central banking, the spending of seigniorage for the welfare of community members, development of asset-backed currencies (following ṣukūk structures), as well as multiple international reserve currencies and joining of hands by professionals and Sharīʿah scholars to design a currency system compatible with the Islamic financial system. This paper’s recommendation is against the adoption of cryptocurrency that lacks the backing of real assets.

The study contributes to the literature by evaluating the compatibility of existing currency systems in the achievement of socio-economic objectives of a welfare state which seeks to uphold justice and equitable resource distribution as core values in the financial system.

Islamic capital markets, i.e. ICMs, featured as socially responsible investments, less levered and more reflective of the real sector, are a recent development in financial markets showing an impressive growth and offering the potential for portfolio diversification benefits. The purpose of this study is to understand the long-run integration of ICMs in the Asia/Pacific region.

This sample includes ICMs of Asia/Pacific region (such as Pakistan, India, China, Japan, Thailand, Malaysia and Indonesia) for 280 weeks between 2011 and 2016. Selected indexes are FTSE Islamic except for Pakistan and Indonesia. Evidence was obtained through the application of correlation, unit root, Johansen cointegration and Granger causality tests.

This study documents the results of the integration of ICMs based on developmental stage, geographic location, economic cooperation and shared religious beliefs/civilization. Partial support was observed for all hypotheses: integration of markets based on economic grouping, location, economic treaties and shared civilization. The Japanese market was the most integrated, while the Indian and Malaysian markets are the least. Evidence supports the shift of leadership role from advanced markets to emerging markets.

Selected diversification opportunities are available for global Islamic as well as conventional investors. This study recommends closer cooperation among Muslim majority countries of the region, as well as the effective use of economic cooperation treaties for joint economic growth and prosperity.

This study contributes to the literature by providing evidence on the integration of ICMs in an economically important region (Asia/Pacific) that is witnessing an increasing role in the global gross domestic product and international trade.
