Abstract

Purpose

Vertical-cavity surface-emitting laser (VCSEL) is a high-performance semiconductor device made of unique epitaxial layers grown on n-type GaAs or InP substrates. The VCSEL’s thermal resistance, Rth, is an essential metric that reflects its thermal properties and dependability. The purpose of this paper is to develop packaging for 1 mm2 VCSEL chips made of a variety of materials, such as ceramic, lead frame and printed circuit board (PCB)-based packaging, as well as provide an idea or design that can withstand and perform well in terms of Rth and heat dissipation during operation. SolidWorks 2017 and AutoCAD Mechanical 2017 software were used to publish all thoughts and ideas, including the size dimensions (x, y and z) and material choices for each package.

Design/methodology/approach

Following the modelling and material selection, the next step is to use the Ansys Mechanical Structural FEA Analysis software to simulate all packaging for Rth and determine which packaging produced the best result, therefore, determining the heat dissipation for each packing. All parameters were used based on the standard cleanroom requirement for the industrial manufacturing backend process, where the cleanroom classification is 10,000 particles (ISO 7). The results demonstrated that the ceramic and lead frame provided good Rth values of 7.3 and 7.0 K/W, respectively, when compared to the PCB, which provided more than 80 K/W; thus, the heat dissipation for PCB packaging also increased.

Findings

As a result of the research, it was determined that ceramic and lead frame packaging are appropriate and capable of delivering good Rth and heat dissipation values when compared to PCB. In comparison to PCB, which requires numerous modifications, such as adding via holes and a thermal bar in an attempt to lower the Rth value, neither packaging requires improvement. Ceramic was chosen for development based on Rth's highest performance, with the actual device consisting of a lead frame and PCB. The Zth measurement test was carried out on a ceramic package, and the Rth result was comparable to the simulation result of 7.6 K/W, indicating that simulation was already proved for research and development.

Originality/value

The purpose of this study is to determine which proposed packaging design would give the highest Rth performance of a 1 mm2 chip as well as the best heat dissipation. In comparison to other studies, VCSEL packaging used the header and window cap as package components with a wavelength of 850 nm, and other VCSEL packaging developments used the sub mount on ceramic package with an output power ranging from 500 mW to 2 W, whereas this study used a huge wavelength and an output power of 4 W.

Abstract

Purpose

The purpose of this paper is to present the investigation of damage severity of reinforced concrete (RC) beam subjected to increasing fatigue loading using intensity of acoustic emission (AE) signal.

Design/methodology/approach

Together 17 RC beams with dimension of 150 × 150 × 750 mm were prepared. Third point loading fatigue test was performed based on load at the first crack (Pcr) and the ultimate static load (Pult). The frequency of 1 Hz was used with the increasing fatigue loadings, 0.5Pcr (P1), 0.8Pcr (P2), 1.0Pcr (P3), 0.2Pult (P4), 0.5Pult (P5) and 0.6Pult (P6). The damage severity of crack for each phase of loading allowed the identification of the crack modes of the beams, namely, Zone A (no significant emission), Zone B (minor), Zone C (intermediate), Zone D (follow-up) and Zone E (major).

Findings

The intensity analysis indicated clear trend with respect to crack propagation in the beam and, hence, can be used to monitor the crack occurrence in the beam.

Originality/value

The intensity analysis has been carried out for the beam subjected to increasing fatigue loading. The analysis was based on the AE data obtained from channel basis and located event.

Abstract

Purpose

The purpose of this paper is to evaluate mentoring behaviours in a public medical school in Malaysia and examine factors associated with those mentoring behaviours. The study is important because effective mentoring promotes the personal and professional growth of mentees.

Design/methodology/approach

A cross-sectional study was conducted with a population of 632 medical students. The authors used the Mentor Behaviour Scale (MBS) to measure four domains of mentoring behaviour: mentoring relationship structure, engagement, autonomy support and competency support. The authors evaluated the scoring of these domains as high, moderate or low scores.

Findings

A total of 508 (80.4 per cent) medical students in Years 2–5 participated in this study. Mentoring relationship structure, engagement and competency support were perceived as moderate scores, whereas autonomy support was perceived as a low score. Students in the early phases of study had better attitudes regarding mentoring behaviours. More frequent meetings and longer duration of meetings were significantly associated with better attitudes towards mentoring behaviour.

Originality/value

This paper evaluates contemporary mentoring behaviours in a Malaysian public medical school and contributes to non-western literature on mentoring. These behaviours were reflected in the four domains of the theory-based MBS.

Abstract

Purpose

This paper aims to explore the level of hibah knowledge among Muslims in Kedah and investigate its determinants, consisting of education level, education stream, religiosity, social influence and social media.

Design/methodology/approach

This study is quantitative in nature. Questionnaires were distributed to collect data from Muslims in Alor Setar, Kedah. In total, 195 questionnaires were collected and data were analyzed using descriptive analysis, correlation analysis and multiple regression analysis.

Findings

The study finds that Muslims in Alor Setar, Kedah have good knowledge of hibah. Further, education stream, religiosity, social influence and social media were identified as significant factors that influence their knowledge of hibah.

Research limitations/implications

The first limitation is its narrow focus in surveying Muslims only in Alor Setar, Kedah. The second limitation is the limited number of determinants used in investigating hibah knowledge among Muslims and the techniques used in analyzing the data. Despite these limitations, the study’s findings provide invaluable insights into the factors influencing hibah knowledge among Muslims in Alor Setar, Kedah.

Practical implications

This study provides insights regarding the significant personal factors and environmental factors to increase Muslims’ knowledge of hibah. The link between the Islamic education stream and hibah knowledge provides a clear indication that Islamic education can curb the economic problems caused by the substantial amounts of frozen and unclaimed assets in Malaysia. A significant relationship between the environmental factors (social influence and social media) and hibah knowledge also implies that the government and private agencies related to Islamic estate planning and management may use these significant determinants as part of the marketing strategy to increase the usage of hibah as an alternative tool for estate planning.

Originality/value

This study contributes to a better understanding of Muslims’ knowledge about hibah. The government and related agencies in Islamic estate planning and management can now gain better insights into Muslims’ level of knowledge about hibah and the factors influencing their knowledge of hibah as an effective tool for Islamic estate planning and management. Hence, more effective strategies can be recommended to enhance the knowledge of Muslims on hibah. The findings of this study should be of value to the government in its effort to address the increasing number of frozen estates in Malaysia.

Abstract

Purpose

Successfully fostering employee ecological behaviors can reduce the environmental impacts of an organization while boosting performance. This paper aims to investigate the factors and organizational strategies for employees to engage in ecological behaviors.

Design/methodology/approach

The study uses a qualitative method. Academicians from four top-ranked research universities from Malaysia participated in semi-structured interviews.

Findings

The in-depth analysis of the interviews identified several factors (environmental attitude, feedback, green self-efficacy, leadership role, organizational culture and employee empowerment) and strategies (incentives; top management support; creating environmental knowledge and awareness; rules and regulations; and sustainability advocates) for promoting ecological behavior in the workplace.

Research limitations/implications

This study was limited to Malaysian public research universities. Future research could investigate additional variables that might influence employee ecological behavior. Implications include policymaking, which emphasizes boosting environmental factors among academicians.

Originality/value

Research studies on employee ecological behavior are minimal. This research contributes to the literature by discussing how different stimuli and strategies are used in the top four-ranked green universities of Malaysia for ecological behavior in the workplace.

Abstract

Purpose

This study aims to examine the three dimensions of market orientation, namely, customer orientation, competitor orientation and inter-function coordination, which influence the accountability in the financial and social performance of tourism operators in large touristic cities.

Design/methodology/approach

In total, 95 usable questionnaires as the required data were collected from the top managers of four- and five-star hotels in Iran.

Findings

Partial least squares (PLS) results confirm that customer orientation and inter-function coordination influence both the financial and social performance of the hospitality sector yet reveal that competitor orientation has no significant relationship with social performance.

Research limitations/implications

These findings not only highlight the compatibility of PLS with various forms of statistical analyzes but also furthers the current understanding of hospitality networks in megacity economies, where literature are scarce.

Practical implications

The findings of this study can help policymakers, tourism associations and practitioners enhance the accountability and sustainable financial and social performance of the hospitality industry in megacities. This study proposes some unique measurements for the social and financial performance of the hospitality sectors.

Originality/value

The paper states some new measurements for the social performance of the hospitality sectors. In addition, measuring the impacts of market orientation on the financial and social aspects of hotels is totally unique.

Abstract

Purpose

This study aims to examine the structural power wielded by the audit committee (AC) and the various bases of its power, whilst also exploring the behavioural tactics used by the AC to leverage its power in the oversight of the external audit.

Design/methodology/approach

Empirical evidence was drawn from semi-structured interviews with external auditors and AC members in Malaysia.

Findings

The AC’s structural power is derived from its formal and network position in the organisation. The AC possesses three forms of organisational-based power (legitimate, coercive and informational) resultant from its formal position, and these combine with the AC’s personal power (will and expert). The AC uses its personal power base to develop trusting relationships and to promote the exchange of information with other key corporate governance actors in the network position. Furthermore, the AC applies at least four behavioural tactics (assertiveness, ingratiation, rationality and coalition formation) to exercise its bases of power.

Originality/value

This study attempts to describe the AC’s structural sources of power, its organisational and personal power bases, and the behavioural tactics it uses when exerting its power.

Abstract

Purpose

This study aims to conceptualize the basic Islamic marketing (IM) process according to Shari’ah, addressing some of the queries raised by scholars on halal and marketing.

Design/methodology/approach

A qualitative approach and content analysis have guided to shape segmentation, targeting and positioning (STP) with the help of secondary data from conventional and IM. Required Qur’anic verses and hadiths have been galvanized to shape STP in line with empirical evidence, showing potential marketing implications.

Findings

This study has accepted Islamic resources to segment markets, mentioning mankind, non-Muslims, Muslims, generic, halal and Islamic products. It has proposed to target mankind, non-Muslims markets with generic and halal products. Muslim marketers can target the pious Muslim consumers with Islamic products. For positioning, the halal certification has been suggested for the non-Muslim marketers and Islamization is for Muslim marketers. The whole process has been conceptualized in a single framework.

Practical implications

Marketers can have many product development ideas and basic guidelines and scholars may be able to sense some queries as to IM.

Social implications

This study has shown how inter-religious relationships can be harmonized with carrying out marketing functions to keep the social fabric following the Qur’anic verses.

Originality/value

This study has outlined the IM process as per Muslim and non-Muslim marketers’ needs under Shari’ah. Besides, it has answered some questions on halal and IM that has been hardly addressed before.

Abstract

Purpose

The purpose of this study is to investigate the impact factors towards the use of mobile banking among the asnaf for efficient zakat payments by using the unified theory of acceptance and use of technology (UTAUT2) model with additional constructs such as religiosity, attitude and trust (initial trust model) in the Malaysian context.

Design/methodology/approach

The structural equation modelling is used to analyse the data collected from 470 asnaf in Selangor, Malaysia, using the survey methodology.

Findings

This study highlights factors that could influence the asnaf to adopt financial technology (fintech) in order for them to enjoy the benefit of efficient zakat distribution by the zakat institutions.

Research limitations/implications

This study only investigates and contributes added value from the Malaysian context. While it may be similar to other countries that share similar demographic profiles, it might differ for countries that do not have any demographic similarities with Malaysia.

Practical implications

The result of this study highlights the significant factor that practitioners (zakat institutions) in Malaysia could improve fintech adoption and at the same time enhance the efficiency of zakat distribution for the asnaf.

Social implications

This research is basically addressing Islamic social financing. Thus, this study has social implications to address the society's poverty eradication scheme pertaining to the efficiency of zakat institutions in Malaysia for the speedier zakat payments to the asnaf. However, other emerging issues also arise particularly in using the zakat funds by the zakat institutions. By right whatever expenditure that the institutions use from the zakat funds need to have the consent from the asnaf because of their religious and legal rights. Hence, this new gap found from the findings of this study could be further explored by other researchers in future studies especially focusing on the drive towards more efficient administration by the zakat institutions of Malaysia in particular and other zakat institutions spread over Muslim countries elsewhere.

Originality/value

This study found that the UTAUT2 model is rarely used and adopted in investigating technology acceptance and adoption especially when it is related to religious matters such as zakat. Indeed, the findings of this study could be acknowledged as something of original value and significance, therefore contributes to the body of knowledge in this field.

Abstract

Purpose

The purpose of this study is to identify Halal hotel attributes demanded by the Russian Muslim travelers. Following this, the study aims to investigate whether gender and types of travelers influence the demand for Halal hotel attributes.

Design/methodology/approach

Semi-structured interviews were conducted to localize the list of Halal hotel attributes for the Russian business context. A self-administrated online questionnaire was designed, distributed and collected from 191 Russian Muslim customers, who have stayed at Halal hotels in the past 12 months. Data analysis includes a t-test and analysis of variance.

Findings

The study revealed a list of Halal attributes demanded by Russian Muslim customers. Also, the findings indicate that the list of the attributes demonstrated the differences in the requested attributes between gender and types of travelers.

Research limitations/implications

The study came across three main limitations. The first was that the respondents surveyed were leisure tourists. Second, the majority of the respondents have university degrees. Third, the research sample is limited to approximately 200 respondents. This research primarily contributes to tourism and hospitality management, and consumer behavior literature, as this is the first study yielding insights on a new demographic: Russian Muslim tourists.

Practical implications

The study provides a clear understanding of the Halal hotel attributes demanded by Russian Muslims that can help hotel managers to accommodate the needs of this group while, at the same time, meeting the requirements of guests of different religions.

Social implications

The study contributes to improving social relationships within the Russian Federation as it improves society’s understanding of the life principles of Muslims.

Originality/value

This is the first study investigating the demand for Halal attributes by Russian Muslim tourists. By partly covering the empty research field on this topic, the study provides meaningful direction to future research of the Russian hotels’ Halal services from both supply and demand perspectives.
