The purpose of this paper is to empirically test for submarket existence based on an understanding of the residential rental housing market in Ghana.

Based on extant literature and market observations, the authors provide key concepts and an overview of the residential rental market dynamics in Ghana. Reseachers appreciate that submarkets may exist in the Ghanaian rental market but have ignored the empirical testing for submarket existence due to data asymmetries. Based on real estate experts and stakeholder consultations, a priori delineation of submarkets are constructed based on spatial, structural and a nested approach. Submarket existence is tested using the Kruskal–Wallis H test and Hedonic modelling techniques.

By using fieldwork data from Accra rental market, the analysis provides credence to the conceptualisation of submarkets and how to empirically test for same. It is argued that researchers should use alternative methods to compare results to make far-reaching conclusions.

Examining the hypothesis that differential rental values exists for submarkets has implications for policy decisions to target submarket constructs differently to improve market maturity.

The research provides stakeholder investors in the rental space an understanding of market dynamics for profit maximisation, and end-users to maximise utility in deciding where to live – and as such households could benefit from making informed investment decisions on housing.

This research is one of the first attempts to empirically identify and test for submarkets existence in Ghana’s residential rental housing market.

An investigation has been performed on the improved solder wettability of oxidized aluminum (Al) with lead-free solder (96.5Sn-3.5Ag) using Ar-H₂ plasmas. The lead-free solder wettability was raised from 62.2 per cent wetting for Al oxidized in air at 250 C for 4 h to 98.4 per cent wetting of oxidized Al modified by Ar-H₂ plasmas at a certain H₂ flow rate. This study aims to gain insight on the surface characteristics of Al affecting the solder wettability with a liquid lead-free solder.

Ar-H₂ plasmas at certain H₂ flow rates are intended to reduce Al oxides on the surfaces of oxidized Al substrates both by physical bombardments via Ar plasmas and chemical reductions with H₂ plasmas, while Al substrates are exposed in Ar-H₂ plasmas to improve the solder wettability with a liquid lead-free solder.

Surface characteristics of oxidized Al substrates have been identified to play key roles for enhanced lead-free solder wettability using Ar-H₂ plasmas. A decrease in polar surface free energy and an increase in dispersive surface free energy on the surfaces of oxidized Al substrates are exploited to advance the lead-free solder wettability. Decreased composition ratios of O to Al, detected by X-ray photoelectron spectroscopy (XPS) for oxidized Al substrates, are crucial for improved lead-free solder wettability.

XPS is typically used to analyze the surface compositions of Al oxides. To provide a rapid and non-expansive method to identify the surfaces of Al substrates prior to soldering to assure lead-free solder wettability, this study proposes a measurable skill, a so-called sessile drop test method, to investigate surface free energies such as total, polar and dispersive surface free energy on the surfaces of Al substrates, to illuminate how the lead-free solder wettability of oxidized Al is improved by Ar-H₂ plasmas.

Human libraries are special libraries that give access to real persons known as “human books.” Readers “check out” human books by attending reading sessions organized by the human library. The majority of previous studies focus on reporting the achievement of human libraries, especially on reducing prejudice and promoting social inclusion. There is a dearth of research to investigate how a human library serves and interacts with society. In this regard, this study aims at examining the operation, development, opportunities and challenges of the New Taipei City Human Library (NTCHL), the first and largest human library in Taiwan.

This study adopts a triangulation methodology to collect and analyze a multitude of data. Participatory observation intends to understand the operation of the NTCHL. In-depth interview is conducted to collect the opinions of the staff of the NTCHL to identify the challenges and opportunities of the human library. Content analysis on relevant documents is performed to review the development and performance of the NTCHL.

Results indicate that the NTCHL has successfully developed a good collection of human books. The NTCHL not only provides an alternative channel of learning, but also helps build connections between community members. The number of book loans and readers has substantially increased since NTCHL' inception, indicating an increasing demand for human library services in Taiwan. While the NTCHL strives for providing readers with better and diversified services, the issues of limited involvement and commitment of human books, heavy workload and the difficulty to establish a good collection of human books need to be addressed.

This study investigates a human library in Taiwan, but human libraries in different places are different in some aspects because those human libraries' social contexts are different. Future studies are recommended to compare the similarities and differences between different human libraries systematically. Furthermore, this study identifies the benefits of the human library but human library's effectiveness is not quantified and evaluated. Future studies may conduct quantitative assessments to fill the research gap.

Human libraries must strive for providing better and diversified services to readers, but there are implications for workload and administration. The experience of the NTCHL may cast light on the future development of human libraries in Taiwan and other countries around the world.

This study shows that the NTCHL has brought a couple of benefits to the society of Taiwan. First, the NTCHL provides readers with an alternative experience of reading. This is an effective way to transmit informal or tacit knowledge. Second, building connections between community members was another benefit of the NTCHL. As modern people are becoming more accustomed to virtual life on the internet which suppresses interpersonal communication, the NTCHL represents an effective platform for communication and sharing of interpersonal experiences.

The novelty of this study is the use of triangulation methodology to investigate the operation, development, opportunities and challenges of the first and largest human library in Taiwan. The findings of this study may cast light on the future development of human libraries in Taiwan and other countries.

The purpose of this study is to develop resin composite materials composed of polycaprolactone (PCL) acrylates and hydroxyapatite (HA) nanoparticles for ultraviolet digital light projection (DLP) three-dimensional (3D) printing technique.

Two PCL-based triacrylates, namely, glycerol-3 caprolactone-triacrylate (Gly-3CL-TA) and glycerol-6 caprolactone-triacrylate (Gly-6CL-TA) were synthesized from ring-opening polymerization of ε-caprolacton monomer in the presence of glycerol and then acrylation was performed using acryloyl chloride. 3D printing resins made of Gly-3CL-TA or Gly-6CL-TA, 5% HA and 3% of photoinitiator 2,4,6-Trimethylbenzoyl-diphenyl-phosphineoxide were then formulated. The surface topography, surface element composition, flexural strength, flexural modulus, cytotoxicity and degradation of the PCL-based scaffolds were then characterized.

Resin composite composed of Gly-3CL-TA or Gly-6CL-TA and 5% (w/w) of HA can be printed by 405 nm DLP 3D printers. The former has lower viscosity and thus can form a more uniform layer-by-layer structure, while the latter exhibited a higher flexural strength and modulus after being printed. Both composite materials are non-cytotoxic and degradable.

This study provides a direction of the formulation of environment-friendly resin composite for DLP 3D printing. Both resin composites have huge potential in tissue engineering applications.

This study analyzed the relationships among sub-factors of mindfulness and two anti-consumption lifestyles caused by personal and social/environmental concerns. This study also investigated the pursuit of authenticity mediating this relationship.

A survey based on self-administered questionnaires and structural equation modeling was used to analyze the collected data via Statistical Product Service Solutions (SPSS) 23 and Analysis of MOment Structure (AMOS) 23. Multiple mediation analysis was adopted to investigate the mediating role of authenticity dimensions via SPSS PROCESS macro.

The relationship between mindfulness and anti-consumption behavior was generally positive. Except for describing and non-judgment, most facets of mindfulness were positively related to anti-consumption patterns. Only the indirect effect of authentic living (AL) was significant in the impact of mindfulness on anti-consumption behavior.

To the authors' knowledge, this study is the first to examine the link between mindfulness and anti-consumption and potential mechanism of anti-consumption – authenticity seeking, extending knowledge about mindfulness and providing insights for environmentalists, public decision-makers, marketers and consumers.

Consumer behaviors in internet are changing over time. The purpose of this paper is to propose and examine a research model that describes the repurchase behavior for the legal and paid music products of physical genre and online genre. The consumption value theory is used to develop the research model. Comparison of physical genre with online genre is presented. Implications and suggestions are addressed.

The research model is examined empirically. The research targeted music product consumers who had purchasing experience in the past one year. The research results are obtained, and the findings are revealed on the basis of 728 valid music product consumers.

The functional, emotional and epistemic value are the significant driving factors, though it shows a limited distinction for the two types. In comparing of the concepts of designed functional value, physical music consumers tend to have a stronger enthusiasm in music consumption. Social value and conditional value are not the predicators of repurchase satisfaction, implying that the music consumption is self-oriented for any normal amusement. The epistemic value shows significant on all levels of significance for the physical type, whereas insignificant if a = 0.01 for the type of online.

The research model is applied for the two contrariety product types, and to make a comparison, trying to understand the reasons why music fans are still willing to spend money on music products and what factors make them choose between product genres. After fluctuation and alternation of the music industry within this decade, this research provides a reference and correlated results for the future studies for the related studies, especially for the prosperous physical parallel imports items and online music.

The aim of this paper is to examine the effects of light controlling system that combined high refractive particles (n-TiO₂ [titanium dioxide – TiO₂]) and tartrazine lake dye (TL dye) on thickness, flexural strength, flexural modulus and surface details of the 3D-printed resin.

Influences of different concentrations of n-TiO₂ and TL dye in light-cured resin formulations for 3D printing (3DP) application were evaluated, including curing thickness, flexural strength and surface details under scanning electron microscopy.

The polymerization thickness of samples containing both n-TiO₂ and TL dye was lower compared to samples with TL dye solely. Samples containing more n-TiO₂ and more TL dye exhibited lower flexural strength and modulus. Ramp models showed that for samples containing 1 per cent TL dye, when their n-TiO₂ content increased from 1 to 5 per cent, surface laminate structures became sharper. However, when the TL dye content doubled to 2 per cent, the surface laminate structures were indefinite compared to 1 per cent TL dye-containing counterparts.

In visible-light 3DP, light controlling system in cooperate dye with high refractive particles provides better energy distribution and scattering control. High refractive particles, dyes and light exposure time had influenced the surface resolution and mechanical properties of the 3DP products.

The COVID-19 pandemic had a disastrous impact on a substantial number of Filipino seafarers. The government agencies played a crucial role in helping the seafarers. This paper aims to explore the challenges that the Filipino seafarers faced amid the pandemic and initially evaluate the Philippine government’s countermeasures.

This paper reviewed academic literature and secondary data to identify and analyze the impact of the COVID-19 pandemic on seafarers. To identify the full range of policies and measures that have been adopted by the Philippines’ government amid the pandemic to mitigate the impact on seafarers, an extensive survey of various sources was conducted. Furthermore, an analytic hierarchy process (AHP) survey was conducted from seafarers' perspective to analyze the priority of these government initiatives.

This study identifies four key challenges for seafarers during the pandemic: crew change crisis, healthcare shortages, certification and the derived problems including financial and mental health issues. Notably, mental health problems are prevalent but receive limited government attention. Despite the government’s efforts to assist seafarers, the AHP survey identifies crew change assistance as the most crucial issue, possibly impacting all others.

This paper recognizes the significant information regarding aid in recovery management and provides much-needed assistance to seafarers during the pandemic and similar crisis situations. It bridges the research gaps and contributes knowledge to the government, stakeholders and various entities such as shipping companies, ship management firms and seafarers' manning agencies.

With the diverse, heterogeneous nature of relationships being a key characteristic of service supply chains, their management is an important area for consideration. This is particularly true in the maritime logistics industry, yet the factors that lead to this heterogeneity are less well understood. This paper aims to explore the structure of relationships within the maritime logistics network and determine why they vary.

Interviews were carried out with 41 practitioners involved in the Taiwanese maritime logistics network. The data from these interviews were analyzed using thematic analysis and quasi-quantification.

The interviews identify that structural holes exist within this maritime logistics network, and that these particularly influence the relationships within this sector with ports being significantly affected. However, five factors are particularly identified that can further impact the strength of these relationships. Often, weak links between ports and both cargo owners and freight forwarders emerge as value-added services are provided by the network.

The findings are framed in a Taiwanese context, where cultural and political norms may give different results to other geographical regions. The research also limits consideration to containerized flows.

By providing detailed insights into relationship structures within the maritime logistics network, managers can take steps to develop appropriate links with other members of the network, reflecting upon the factors that lead to heterogeneity.

This paper expands knowledge on logistics service supply chains, identifying the importance of relationships in a derived demand environment. For maritime researchers, specific factors leading to relationship heterogeneity in the network are detailed, to inform future research.
