Authors: Che Embi Nor Azizan , Kassim Salina , Ramlee Roslily , Wan Husain Wan Rohaida
Published: October 2021

Housing affordability is important to ensure houses are affordable to everyone across all income categories, whether they are in the low-income, middle-income (M40), or high-income group. Building housing projects on waqf land will help increase the supply of affordable houses, especially targeted at the M40 group, while also addressing the shortage of affordable housing for the M40 cohort. This study analyses public perceptions of house characteristics and relate these factors to affordable housing prices. The independent variables are location, infrastructure, facilities, size, design and quality. By applying a quantitative research design, the study aims to understand the relationship between various demanded housing characteristics vis-a-vis the price of the house. A sample of 261 usable responses was analysed using the Structural Equation Modelling (SEM). The results show that house size is not statistically significant in influencing the housing price, while location, infrastructure and design of the house are positively significant factors. These findings are expected to provide important inputs to the relevant authorities on factors that are critical in influencing the prices of housing projects built on waqf land in Malaysia.

Authors: Jamaludin Mohamad Hafiz , Ismail Suriatini , Ismail Norziha
Published: October 2021

The index is considered an important benchmark and is a decision-making tool in the financial and capital markets, as well as in the property market. In Malaysia, continuous monitoring of property price movements is important as almost half of banking exposure is on property. Further, NAPIC has published indicators displaying the performance of property such as MHPI and PBO-RI. However, indicators regarding the price of commercial property are still less widely published in Malaysia. This study was conducted to develop indicators related to the price of commercial property, especially to shop property. This study has focused on the state of Penang as a study area. The literature review methodology is used to identify existing methods and practices used in developing the index of commercial property both in Malaysia and internationally. In determining the appropriate form of hedonic functions for the development of PSPI, analysis of dependent and independent variables was performed. Meanwhile, the development of the index is based on the Laspeyres hedonic model which is the same as the development of MHPI and PBO-RI. The development of PSPI will be able to help the industry and investors to make decisions and benchmark the performance of shop. This is also one of the pilot studies in Malaysia to form an indicator of commercial property.

Authors: Lim Wendy Wen Xin , Burhan Burhaida , Mohd Diah Mohd Lizam
Published: October 2021

Housing is a country’s biggest asset. Hence, the pattern of the housing price index (HPI) is an important topic to gain insight into the housing market while identifying the prevailing housing issues. The determinants of housing price vary for each city and state based on the different characteristics in each location. Accordingly, HPI should consider the property’s quality differences. Besides, national HPI is insufficient and restricted to the housing price at the state level. Thus, the study focused on constructing a specified HPI model for different cities, districts, and states. Effective HPI can give parties a better idea of the current property market situation and act as an analytical tool in managing the sector. Specifically, the study aims to examine the relationship between the heterogeneity housing attributes and housing prices of the terraced properties in Johor Bahru, Malaysia. Additionally, the study provides detailed information on the key determinants of the housing price variation in Johor Bahru. Hedonic price analysis is useful in constructing HPI, expressing housing price as a function of vector property characteristics. Furthermore, HPI is constructed based on the yearly indices and by pooling the data into certain periods. The results show the percentage of variance explained by the factors of HPI for the terraced properties in Johor Bahru. Correspondingly, the underlying correlation between the tested housing attributes with the housing price is explained through the analysis results.

Published: October 2021

Maintenance data for government buildings in Putrajaya, Malaysia, consists of a vast volume of data that is divided into different classes based on the functions of the maintenance tasks. As a result, multiple interactions from stakeholders and customers are required. This necessitates the collection of data that is specific to the stakeholders and customers. Big data can also forecast for predictive maintenance purposes in maintenance management. The current data practise relies solely on well-structured statistical data, resulting in static analysis and findings. Predictive maintenance under the Big Data idea will also use non-visible data such as social media and web search queries, which is a novel way to use Big Data analytics. The metamodel technique will be used in this study to evaluate the predictive maintenance model and faulty events in order to verify that the asset, facilities, and buildings are in excellent working order utilising systematic maintenance analytics. The metamodel method proposed a predictive maintenance procedure in Putrajaya by utilising the big data idea for maintenance management data.

Published: October 2021

This research uses principal negotiation theory to identify further a dispute emerging between the state asset manager, the central government, and the special local government, the sultanate government. This study examines the dispute resolution and the implementation of the dispute resolution between applying the Yogyakarta Privileges Act to the management of State Property. This research uses study literature, secondary data and then is analyzed qualitatively. This study explains that dispute resolution outside the court is more effective and efficient in managing state property. The costs incurred are enormous, and the time required is extensive. Therefore, it is better to immediately design policies, breakthroughs, and arrangements for resolving disputes between state property and sultanate ground. This study was conducted in the Indonesian context. However, the study's findings may not be generalizable to State Asset Management in other countries, especially the Western ones. These findings are likely to have significant implications for State Asset Management in designing and implementing how to resolve dispute problems in asset management in the unique region of Yogyakarta.

Published: October 2021

The plan to relocate the Indonesian capital from Jakarta to East Kalimantan Province in 2024 requires a significant amount of 442 trillion Rupiah to construct various new capital infrastructure such as roads for transportation. This study aims to analyze the funding scheme for new capital road construction projects in Indonesia using two alternative financing, namely the National Budget and Public-Private Partnership (PPP). This study used quantitative methods with a scenario analysis approach to determine the best funding scheme based on regional economic growth and financial viability. This study did not consider the project management factors during the construction period and the quality factors of the roads built during the concession period. The results showed that road construction projects in the new capital city can be implemented using two financing schemes. The National Budget financing scheme will increase the percentage of the budget deficit to GDP in the first five years of development. The financing scheme through PPP can help the government overcome the budget deficit but requires the resilience of the government's budget during the project concession period.

Published: October 2021

Heritage property value is an important economic indicator to a country. Thus, it is imperative that the value is derived from an accurate and reliable method of valuation. However, in Malaysia, there are no specific standards that can be referred to for conducting an assessment for heritage property valuation. Thus, this paper fills the gap by reviewing five provisions of the Malaysian laws and four provisions of the international laws that are related to heritage property valuation. Thematic analysis of the documents is undertaken by using five keywords that relate to heritage property valuation, namely: definition, factors, method, procedure and type of values. Out of nine legal documents analysed, Valuation of Specialised Public Service Assets has the most information needed as a guidance for heritage property valuation.

The electrical contact resistance significantly affects the efficiency of thermoelements. In the case of high doped thermoelectric materials, the tunneling mechanism of conductivity prevails at metal-semiconductor interface, which makes it possible to obtain a contact resistance of less than 10-8 Ohm•m2. Low resistance values significantly complicate its experimental determination. Work present three techniques and a measuring stand for the investigation of contact resistance. The techniques are based on the measurement of the total electrical resistance, which consists of transient contact resistance and the resistance of the thermoelectric material with its subsequent exclusion. The developed techniques differ in the arrangement of the investigated contacts on the samples, in the methods of measurement and processing of the obtained results, and make it possible to determine the specific contact resistance of the order of 10-10 Ohm•m2.

Temperature response of a material to an external electric field is the main method for electrocaloric effect study in ferroelectrics. In this work, for 0.65 PbFe2/3W1/3O3 – 0.35 PbTiO3 solid solution as a model object, it is shown that with an increase in the electric field strength, current filamentation effect can occur. It leads to formation of local regions of increased conductivity in the sample. The associated thermal effect have short characteristic times, due to the small volume of the filament. They are comparable to the times of the electrocaloric response of the material, and can lead to significant errors in the detection of the electrocaloric effect.

The Use of a Formative Pedagogy Lens to Enhance and Maintain Virtual Supervisory Relationships: Appreciative Inquiry and Critical Review
Authors: Jordan Chloe Louanne , Sathaananthan Thillainathan , Celi Leo Anthony , Jones Linda , Alagha M Abdulhadi
Published: October 2021

Background

Virtual supervisory relationships provide an infrastructure for flexible learning, global accessibility, and outreach, connecting individuals worldwide. The surge in web-based educational activities in recent years provides an opportunity to understand the attributes of an effective supervisor-student or mentor-student relationship.

Objective

The aim of this study is to compare the published literature (through a critical review) with our collective experiences (using small-scale appreciative inquiry [AI]) in an effort to structure and identify the dilemmas and opportunities for virtual supervisory and mentoring relationships, both in terms of stakeholder attributes and skills as well as providing instructional recommendations to enhance virtual learning.

Methods

A critical review of the literature was conducted followed by an AI of reflections by the authors. The AI questions were derived from the 4D AI framework.

Results

Despite the multitude of differences between face-to-face and web-based supervision and mentoring, four key dilemmas seem to influence the experiences of stakeholders involved in virtual learning: informal discourses and approachability of mentors; effective virtual communication strategies; authenticity, trust, and work ethics; and sense of self and cultural considerations.

Conclusions

Virtual mentorship or supervision can be as equally rewarding as an in-person relationship. However, its successful implementation requires active acknowledgment of learners’ needs and careful consideration to develop effective and mutually beneficial student-educator relationships.

Harnessing the Electronic Health Record and Computerized Provider Order Entry Data for Resource Management During the COVID-19 Pandemic: Development of a Decision Tree (Preprint)
Authors: Luu Hung S , Filkins Laura M , Park Jason Y , Rakheja Dinesh , Tweed Jefferson , Menzies Christopher , Wang Vincent J , Mittal Vineeta , Lehmann Christoph U , Sebert Michael E
Published: October 2021

BACKGROUND

The COVID-19 pandemic has resulted in shortages of diagnostic tests, personal protective equipment, hospital beds, and other critical resources.

OBJECTIVE

We sought to improve the management of scarce resources by leveraging electronic health record (EHR) functionality, computerized provider order entry, clinical decision support (CDS), and data analytics.

METHODS

Due to the complex eligibility criteria for COVID-19 tests and the EHR implementation–related challenges of ordering these tests, care providers have faced obstacles in selecting the appropriate test modality. As test choice is dependent upon specific patient criteria, we built a decision tree within the EHR to automate the test selection process by using a branching series of questions that linked clinical criteria to the appropriate SARS-CoV-2 test and triggered an EHR flag for patients who met our institutional persons under investigation criteria.

RESULTS

The percentage of tests that had to be canceled and reordered due to errors in selecting the correct testing modality was 3.8% (23/608) before CDS implementation and 1% (262/26,643) after CDS implementation (P<.001). Patients for whom multiple tests were ordered during a 24-hour period accounted for 0.8% (5/608) and 0.3% (76/26,643) of pre- and post-CDS implementation orders, respectively (P=.03). Nasopharyngeal molecular assay results were positive in 3.4% (826/24,170) of patients who were classified as asymptomatic and 10.9% (1421/13,074) of symptomatic patients (P<.001). Positive tests were more frequent among asymptomatic patients with a history of exposure to COVID-19 (36/283, 12.7%) than among asymptomatic patients without such a history (790/23,887, 3.3%; P<.001).

CONCLUSIONS

The leveraging of EHRs and our CDS algorithm resulted in a decreased incidence of order entry errors and the appropriate flagging of persons under investigation. These interventions optimized reagent and personal protective equipment usage. Data regarding symptoms and COVID-19 exposure status that were collected by using the decision tree correlated with the likelihood of positive test results, suggesting that clinicians appropriately used the questions in the decision tree algorithm.

BACKGROUND

This article presents the modeling and development of a Knowledge Based System, supported by the use of a virtual conversational agent called Dóris. Using natural language processing resources, Dóris collects the clinical data of patients in care in the context of urgency and hospital emergency.

OBJECTIVE

The main objective is to validate the use of virtual conversational agents to properly and accurately collect the data necessary to perform the evaluation flowcharts used to classify the degree of urgency of patients and determine the priority for medical care.

METHODS

The agent's knowledge base was modeled using the rules provided for in the evaluation flowcharts comprised by the Manchester Triage System. It also allows the establishment of a simple, objective and complete communication, through dialogues to assess signs and symptoms that obey the criteria established by a standardized, validated and internationally recognized system.

RESULTS

Thus, in addition to verifying the applicability of Artificial Intelligence techniques in a complex domain of health care, a tool is presented that helps not only in the perspective of improving organizational processes, but also in improving human relationships, bringing professionals and patients closer. The system's knowledge base was modeled on the IBM Watson platform.

BACKGROUND

With 1.6 billion users in 2021, TikTok has become the world's fastest-growing social media application ever since its first launch. Because of the explosion of information on it during the COVID-19 pandemic, more and more patients search for information on urinary tumors on TikTok.

OBJECTIVE

We aim to evaluate the quality and reliability of urinary tumor-related videos on TikTok by using robust assessing scales and share our thoughts based on the results for better public health promotion.

METHODS

We retrieved videos on bladder, prostate, and kidney cancer from TikTok. Each video's length and descriptions, hashtags, number of views/likes/comments, forms of expression, and the uploader's profile were included. Three validated assessment instruments: the Hexagonal Radar Schema, the Health on the Net Code scale, and the DISCERN instrument, were used for evaluating the quality and reliability of the information. All misinformation was counted and categorized. Univariate analysis of variance was performed for analyzing the results. The Post-Hoc least significant difference test was conducted to explore further explanation.

RESULTS

Out of 167 retrieved videos, only 61 (36.53%) met the inclusion criteria. Amongst them, 36.07% were misinformative, and the most common type was using outdated data. More than half of the videos could provide good (> 1 point) content on the diseases' symptoms and examinations. However, the definition and outcomes were poorly addressed (tied at 21.31 %). The HONcode scale and the DISCERN instrument revealed a consistent conclusion that most videos on TikTok were of poor to mediocre quality. Videos published by media agencies were statistically better than those posted by others in terms of reliability and overall score (P = .003 and .008, respectively). 86.89% of videos had at least two unexplained medical terms. Among them, healthcare professionals like to use professional terms most (mean = 5.28 words).

CONCLUSIONS

Most videos on urinary tumors on TikTok are of poor to medium quality and reliability. However, videos posted by media agencies enjoyed great public attention and interaction. Medical practitioners could improve the video quality by cooperating with media agencies and avoiding unexplained terminologies.
A New Digital Assessment of Mental Health and Well-being in the Workplace: Development and Validation of the Unmind Index (Preprint)
Authors: Sierk Anika , Travers Eoin , Economides Marcos , Loe Bao Sheng , Sun Luning , Bolton Heather
Published: October 2021

BACKGROUND

Unmind is a workplace, digital, mental health platform with tools to help users track, maintain, and improve their mental health and well-being (MHWB). Psychological measurement plays a key role on this platform, providing users with insights on their current MHWB, the ability to track it over time, and personalized recommendations, while providing employers with aggregate information about the MHWB of their workforce.

OBJECTIVE

Due to the limitations of existing measures for this purpose, we aimed to develop and validate a novel well-being index for digital use, to capture symptoms of common mental health problems and key aspects of positive well-being.

METHODS

In Study 1A, questionnaire items were generated by clinicians and screened for face validity. In Study 1B, these items were presented to a large sample (n=1104) of UK adults, and exploratory factor analysis was used to reduce the item pool and identify coherent subscales. In Study 2, the final measure was presented to a new nationally representative UK sample (n=976), along with a battery of existing measures, with 238 participants retaking the Umind Index after 1 week. The factor structure and measurement invariance of the Unmind Index was evaluated using confirmatory factor analysis, convergent and discriminant validity by estimating correlations with existing measures, and reliability by examining internal consistency and test-retest intraclass correlations.

RESULTS

Studies 1A and 1B yielded a 26-item measure with 7 subscales: Calmness, Connection, Coping, Happiness, Health, Fulfilment, and Sleep. Study 2 showed that the Unmind Index is fitted well by a second-order factor structure, where the 7 subscales all load onto an overall MHWB factor, and established measurement invariance by age and gender. Subscale and total scores correlate well with existing mental health measures and generally diverge from personality measures. Reliability was good or excellent across all subscales.

CONCLUSIONS

The Unmind Index is a robust measure of MHWB that can help to identify target areas for intervention in nonclinical users of a mental health app. We argue that there is value in measuring mental ill health and mental well-being together, rather than treating them as separate constructs.

The Role of Influential Actors in Fostering the Polarized COVID-19 Vaccine Discourse on Twitter: Mixed Methods of Machine Learning and Inductive Coding (Preprint)
Authors: Hagen Loni , Fox Ashley , O'Leary Heather , Dyson DeAndre , Walker Kimberly , Lengacher Cecile A , Hernandez Raquel
Published: October 2021

BACKGROUND

Since COVID-19 vaccines became broadly available to the adult population, sharp divergences in uptake have emerged along partisan lines. Researchers have indicated a polarized social media presence contributing to the spread of mis- or disinformation as being responsible for these growing partisan gaps in uptake.

OBJECTIVE

The major aim of this study was to investigate the role of influential actors in the context of the community structures and discourse related to COVID-19 vaccine conversations on Twitter that emerged prior to the vaccine rollout to the general population and discuss implications for vaccine promotion and policy.

METHODS

We collected tweets on COVID-19 between July 1, 2020, and July 31, 2020, a time when attitudes toward the vaccines were forming but before the vaccines were widely available to the public. Using network analysis, we identified different naturally emerging Twitter communities based on their internal information sharing. A PageRank algorithm was used to quantitively measure the level of “influentialness” of Twitter accounts and identifying the “influencers,” followed by coding them into different actor categories. Inductive coding was conducted to describe discourses shared in each of the 7 communities.

RESULTS

Twitter vaccine conversations were highly polarized, with different actors occupying separate “clusters.” The antivaccine cluster was the most densely connected group. Among the 100 most influential actors, medical experts were outnumbered both by partisan actors and by activist vaccine skeptics or conspiracy theorists. Scientists and medical actors were largely absent from the conservative network, and antivaccine sentiment was especially salient among actors on the political right. Conversations related to COVID-19 vaccines were highly polarized along partisan lines, with “trust” in vaccines being manipulated to the political advantage of partisan actors.

CONCLUSIONS

These findings are informative for designing improved vaccine information communication strategies to be delivered on social media especially by incorporating influential actors. Although polarization and echo chamber effect are not new in political conversations in social media, it was concerning to observe these in health conversations on COVID-19 vaccines during the vaccine development process.

Resilience in 2021—Descriptive Analysis of Individuals Accessing Virtual Mental Health Services: Retrospective Observational Study (Preprint)
Authors: Graziani Grant , Kunkle Sarah , Shih Emily
Published: October 2021

BACKGROUND

Psychological resilience has been extensively studied by developmental researchers, and there is a growing body of literature regarding its role in psychiatry and psychopathology research and practice. This study contributes to this growing literature by providing real-world evidence on the relationship between resilience and clinical symptoms among a large sample of employed Americans.

OBJECTIVE

This study aimed to describe resilience levels in individuals accessing Ginger, a virtual mental health system, in addition to the association of resilience with demographic characteristics, baseline depression, and anxiety symptoms.

METHODS

We conducted a retrospective observational study of 9165 members who signed up for Ginger and completed a baseline survey between January 1 and August 5, 2021. We used multivariate regression models to test for associations between baseline resilience and other member characteristics.

RESULTS

Baseline resilience scores centered on a mean of 23.84 (SD 6.56) and median of 24 (IQR 8) out of 40, with 81.0% (7424/9165) of the sample having low resilience at baseline. Despite having relatively higher resilience scores, members with no or mild depression or anxiety still had low resilience scores on average. Self-reported suicidal ideation was associated with lower resilience.

CONCLUSIONS

Overall, members had low baseline resilience, similar to resilience levels observed in trauma survivors in prior studies. Younger members and those with higher levels of depression and anxiety at intake reported lower levels of resilience at baseline. Notably, members with no or mild depression or anxiety still had low resilience scores on average, suggesting a need for mental health support among individuals who might not typically be recommended for treatment based on traditional clinical assessments, such as the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder scale (GAD-7). Two suggestions for topics of future research are to develop treatment recommendations based on the Connor-Davidson Resilience Scale and to understand the interaction between resilience levels and symptom-based outcome measures, such as the PHQ-9 and the GAD-7.
