Abstract

To achieve integration of chip scale package (CSP) devices into main stream surface mount technology (SMT) assembly, various experiments have been required. In process development, experiences learned from flip chip attach and ball grid array (BGA) assembly were utilized. Key process parameters for CSP assembly were defined and some of those key factors were optimized. They will be presented in this paper. Some observations during prototype build have been documented for correlation with reliability results in the future. The requirements for further CSP assembly studies will also be addressed in this paper.

Abstract

Analysis of Philippine society has largely turned on the collectivist/individualist binary. Taking off from this dualism and from the notion and practice of siblingship (Aguilar, 2013). This chapter looks at two contemporary Filipino family films – Kung Ayaw Mo, Huwag Mo! (If You Don’t Want, So Be It) and Four Sisters and a Wedding. These films articulate and resolve the tensions, ambivalences, and conflicts between self and family, autonomy and dependence, and individualism and collectivism. This chapter also shows how the collectivism–individualism binary has broader political resonance, touches on the relationship between family and democracy, and proposes the family as a complementary point from which to theorize democracy in the Philippines.

Abstract

Purpose

Key challenges in evaluating the performance of a robotic manipulator are disturbances that rise internally and externally. Effects of non-linear disturbances like varying payload and joint friction can adversely affect the tracking performance in a robotic manipulator. This paper aims to discuss motion control of a three-link spatial manipulator using a computed torque observer-based control technique.

Design/methodology/approach

The overall motion control problem consists of derivation of kinematic and dynamic model of the manipulator followed by the control design to achieve desired manipulator response. In this study, the manipulator is subjected to uncertain varying load disturbances. The proposed motion controller compensates the effect of the disturbances and guarantees the convergence of tracking error to steady state value.

Findings

One major advantage of using observer-based control is positioning accuracy with robustness to parameter uncertainty and fast dynamics response. The performance of the proposed control technique is validated through real-time experiments conducted on the manipulator. The experiment results confirm the superior performance of the control system in achieving perfect tracking.

Originality/value

This paper demonstrates an observer-based control technique over a serial spatial manipulator which can be applied different robotic configurations under the effect of varying disturbances.

Understanding whistleblowing behavior by identifying preferred reporting channels and associated personality characteristics can aid organizations in their attempts to encourage

Abstract

Understanding whistleblowing behavior by identifying preferred reporting channels and associated personality characteristics can aid organizations in their attempts to encourage whistleblowing. The authors investigate whether both Dark Triad characteristics and gender affect whistleblowing intentions and whistleblowing channel preferences. Using a sample of undergraduate business students, the authors find individuals with higher levels of Dark Triad personality characteristics indicate that they are less likely to blow the whistle than individuals with lower levels of Dark Triad personality characteristics. They are also more likely to use non-anonymous channels over anonymous channels and individuals with lower levels of Dark Triad personality characteristics show the opposite channel preference. The authors also find women more likely to report, and when reporting, they prefer anonymous over non-anonymous channels. The results provide support for organizations in cultivating an organizational culture that promotes communication among employees and potentially includes incentives to promote whistleblowing.

Abstract

Purpose

This research aims to examine the moderating role of managerial ability on the relationship between risk-taking behavior and firms' performance.

Design/methodology/approach

This research uses 383 manufacturing firm-years listed on the Indonesian Stock Exchange as the research sample. The hypothesis test uses fixed-effect regression analysis.

Findings

The result shows that risk-taking behavior has a positive effect on firms' performance for higher managerial ability. Managerial ability provides higher knowledge, skill and information to get benefits and mitigate costs of risk-taking behavior to improve firms' performance. The role of managerial ability to make risk-taking behavior increase firms' performance occurs more for high-ability managers, dual CEO, shareholder-CEO and family CEO.

Originality/value

This research contributes to answering the conflicting arguments and filling the previous findings gap between risk-taking behavior and firm performance by considering managerial ability as a factor to create effective risk mitigation.

Abstract

The strategic management literature emphasizes the concept of business intelligence (BI) as an essential competitive tool. Yet the sustainability of the firms’ competitive advantage provided by BI capability is not well researched. To fill this gap, this study attempts to develop a model for successful BI deployment and empirically examines the association between BI deployment and sustainable competitive advantage. Taking the telecommunications industry in Malaysia as a case example, the research particularly focuses on the influencing perceptions held by telecommunications decision makers and executives on factors that impact successful BI deployment. The research further investigates the relationship between successful BI deployment and sustainable competitive advantage of the telecommunications organizations. Another important aim of this study is to determine the effect of moderating factors such as organization culture, business strategy, and use of BI tools on BI deployment and the sustainability of firm’s competitive advantage.

This research uses combination of resource-based theory and diffusion of innovation (DOI) theory to examine BI success and its relationship with firm’s sustainability. The research adopts the positivist paradigm and a two-phase sequential mixed method consisting of qualitative and quantitative approaches are employed. A tentative research model is developed first based on extensive literature review. The chapter presents a qualitative field study to fine tune the initial research model. Findings from the qualitative method are also used to develop measures and instruments for the next phase of quantitative method. The study includes a survey study with sample of business analysts and decision makers in telecommunications firms and is analyzed by partial least square-based structural equation modeling.

The findings reveal that some internal resources of the organizations such as BI governance and the perceptions of BI’s characteristics influence the successful deployment of BI. Organizations that practice good BI governance with strong moral and financial support from upper management have an opportunity to realize the dream of having successful BI initiatives in place. The scope of BI governance includes providing sufficient support and commitment in BI funding and implementation, laying out proper BI infrastructure and staffing and establishing a corporate-wide policy and procedures regarding BI. The perceptions about the characteristics of BI such as its relative advantage, complexity, compatibility, and observability are also significant in ensuring BI success. The most important results of this study indicated that with BI successfully deployed, executives would use the knowledge provided for their necessary actions in sustaining the organizations’ competitive advantage in terms of economics, social, and environmental issues.

This study contributes significantly to the existing literature that will assist future BI researchers especially in achieving sustainable competitive advantage. In particular, the model will help practitioners to consider the resources that they are likely to consider when deploying BI. Finally, the applications of this study can be extended through further adaptation in other industries and various geographic contexts.

Abstract

Purpose

Some of the major concerns since the implementation of smart meters (prepaid meters) in some parts of Ghana is how electricity consumers have benefited from data obtained from these meters by providing important statistics on electricity-saving advice; this is one of the key demand-side management methods for achieving load reduction in residential homes. Appliance shifting techniques have proved to be an effective demand response strategy in load reduction. The purpose of this paper is therefore to help consumers of electricity understand when and how they can shift some appliances from peak to off-peak and vice versa.

Design/methodology/approach

The research uses an analysis technique of Richardson et al. (2010). In their survey on time-of-use surveys to determine the usage of electricity in households as far as appliance shifting was concerned, this study allowed for the assessment of how the occupants’ daily activities in households affect residential electricity consumption. Fell et al. (2014) modeled an aggregate of electricity demand using different appliances (n) in the household. The data for the peak time used in this study were identified from 05:00 to 08:00 and 17:00 to 21:00 for testing the load shifting algorithms, and the off-peak times were pecked from 10:00 to 16:00 and 23:00. This study technique used load management considering real-time scheduling for peak levels in the selected homes. The household devices are modeled in terms of controlled parameters. Using this study’s time-triggered loads on refrigerators and air conditioning systems, the findings suggested that peak loads can be reduced to 45% as a means of maintaining the simultaneous quality of service. To minimize peak loads to around 35% or more, Chaiwongsa and Wongwises (2020) have indicated that room air conditioning and refrigerator loads are simpler to move compared to other household appliances such as cooking appliances. Yet in conclusion, this study made a strong case that a decrease in household peak demand for electricity is primarily contingent on improvements in human behavior.

Findings

This study has shown that appliance load shifting is a very good way of reducing electrical consumption in residential homes. The comparative performance shows a moderate reduction of 1% in load as was found in the work done by Laicaine (2014). The results, however, indicate that load shifting to a large extent can be achieved by consumer behavioral change. The main response to this study is to advise policymakers in Ghana to develop the appropriate demand response and consumer education towards the general reduction in electrical load in domestic households. The difficulty, however, is how to get the attention of consumer’s on how to start using appliances with less load at peak and also shift some appliances from off-peak times. By increasing consumer knowledge and participation in demand response, it is possible to achieve more efficiency and flexibility in load reduction. The findings were benchmarked with existing comparison studies but may benefit from the potential production of structured references. However, the findings show that load shifting can only be done by modifying consumer actions.

Research limitations/implications

It should be remembered that this study showed that the use of appliances shifting in residential homes results in load reduction benefits for customers, expressed as savings in electricity prices. The next step will be to build on this cost/benefit study to explain and measure how these reductions transform into net consumer gains for all Ghanaian households.

Practical/implications

Load shifting will include load controllers in the future, which would automatically handle electricity consumption from various appliances in the home. Based on the device and user needs, the controllers can prioritize loads and appliance usage. The algorithms that underpin automatic load controllers will include knowledge about the behaviors of groups of end users. The results on the time dependency of activities may theoretically inform the algorithms of automatic demand controllers.

Originality/value

This paper addresses an important need for the country in the midst of finding solutions to an unending energy crisis. This paper presents demand response to the Ghanaian electricity consumer as a means to help in the reduction of load in residential homes. This is a novel research as no one has at yet carried out any research in this direction in Ghana. This paper has some new information to offer in the field of demand in household electricity consumption.

Abstract

Purpose

E-commerce live streaming is a new influencer advertising method that allows influencers to interact directly with consumers on e-commerce platforms. Although evidence suggests that influencer live-streaming advertisements (ads) on social media can increase consumers’ buying impulses, little research examined how this similar but new advertising method on e-commerce platforms may influence consumers’ urge to buy impulsively. This study explores the role of influencer credibility, celebrity effect, perceived entertainment, trust and perceived usefulness on consumers’ attitudes toward influencer ads and their urge to buy impulsively.

Design/methodology/approach

A questionnaire containing seven constructs was developed and distributed to participants using a convenient sample and snowball sampling approach. The constructs were measured based on validated measurement items from the literature and adjusted according to this study’s focus. A total of 236 valid responses were obtained from the survey and used for data analysis. A partial least squares structural equation modeling approach was employed for parameter estimation and model testing.

Findings

The empirical results show that all constructs influenced consumers’ urge to buy impulsively via attitude toward influencer ads. The proposed research model explains 61.7% of the variance in attitude toward influencer ads and 19.4% of the urge to buy impulsively.

Originality/value

This is an early study investigating the relationship between influencer advertising and impulse buying. The results provide valuable insights into improving the design of influencer ads and marketing strategies.

Highlights

  1. I-eIB model tests the mechanism of influencer ads on consumers’ buying impulse.

  2. Consumers’ attitude towards influencer ads affects their urge to buy impulsively.

  3. Influencer credibility affects consumer attitude via celebrity effect as a mediator.

  4. Trust affects consumer attitude via perceived usefulness as a mediator.
