Mechanisms for enhancing the use of social media for knowledge sharing by the construction professionals

Purpose This paper aims to investigate the mechanisms for transforming construction professionals’ intentions into use of social media (SM) for knowledge sharing (KS). The objectives are to: identify the common types of SM platforms used by the construction professionals for KS; identify the key problems influencing transformation of the construction professionals’ intentions into use of SM for KS; identify the factors mitigating the problems; and provide recommendations for enhancing construction professionals’ use of SM for KS. Design/methodology/approach The data was collected through semi-structured interviews with Australian construction professionals and analysed using grounded theory (GT). The outcomes of the analyses formed a framework for the enhancement of SM use for KS. Findings The findings show that private SM followed by enterprise SM are more appealing to the construction professionals for KS compared to public SM; and uncertainties about users’ privacy/confidentiality and the quality of the shared knowledge adversely affect the transformation of the construction professionals’ intentions into use of SM for KS. Three types of trust are identified as the mitigators of the identified problems. A framework is proffered to enhance SM use for KS by construction professionals. Originality/value This paper contributes to the construction literature by developing a GT to explain the factors which impact the transformation of the construction professionals’ intentions into use of SM for KS. Additionally, the practical contribution of this study is the provision of framework constituting recommendations for the enhancement of SM use for KS.
Occurrence, Distribution and Identification of Viruses Infecting Some Cucurbits Across Major Cucurbit-Growing Areas in Cross River State, Nigeria

Cucurbits are group of plants which belonged in the Cucurbitaceae family and constitute one of the most important vegetables for human consumption throughout the world. A survey conducted between January to March 2021 across major cucurbit-growing area in Cross River State revealed wide spread virus infection of these crops, surveyed plants showed mosaic, mottle and leaf deformation symptoms. This research was aimed at identifying viruses infecting some cucurbits in the study areas. Twenty four samples showing virus like symptoms were collected and tested against ACP-ELISA and RT-PCR. Result obtained from ACP-ELISA showed that 20 out of 24 samples collected tested positive to universal potyvirus antisera, the gene sequence analysis revealed that samples were predominantly infected with Algerian watermelon mosaic virus representing 40% of total viruses detected followed by Morroccan watermelon mosaic virus representing 15% of total viruses detected followed by Papaya ringspot virus, Zucchini tigre mosaic virus, Watermelon mosaic virus and Soybean mosaic virus representing 10% each for total viruses detected and finally Potato virus Y representing 5% of total virus detected. This survey is an accurate and timely detection and will form the basis for mitigating yield losses resulting from virus infection on cucurbits. This is the first report of wide scale detection of viruses infecting cucurbits in Nigeria.
Evaluation of the Equity and Regional Management of Some Urban Green Space Ecosystem Services: A Case Study of Main Urban Area of Xi’an City

Urban green spaces can provide many types of ecosystem services for residents. An imbalance in the pattern of green spaces leads to an inequality of the benefits of such spaces. Given the current situation of environmental problems and the basic geographical conditions of Xi’an City, this study evaluated and mapped four kinds of ecosystem services from the perspective of equity: biodiversity, carbon sequestration, air purification, and climate regulation. Regionalization with dynamically constrained agglomerative clustering and partitioning (REDCAP) was used to obtain the partition groups of ecosystem services. The results indicate that first, the complexity of the urban green space community is low, and the level of biodiversity needs to be improved. The dry deposition flux of particulate matter (PM2.5) decreases from north to south, and green spaces enhance the adsorption of PM2.5. Carbon sequestration in the south and east is higher than that in the north and west, respectively. The average surface temperature in green spaces is lower than that in other urban areas. Second, urban green space resources in the study area are unevenly distributed. Therefore, ecosystem services in different areas are inequitable. Finally, based on the regionalization of integrated ecosystem services, an ecosystem services cluster was developed. This included 913 grid spaces, 12 partitions, and 5 clusters, which can provide a reference for distinct levels of ecosystem services management. This can assist urban managers who can use these indicators of ecosystem service levels for planning and guiding the overall development pattern of green spaces. The benefits would be a maximization of the ecological functions of green spaces, an improvement of the sustainable development of the city, and an improvement of people’s well-being.
Efficacy of Video-Based Forearm Anatomy Model Instruction for a Virtual Education Environment

INTRODUCTION As virtual education becomes more widespread, particularly considering the recent COVID-19 pandemic, studies that assess the impact of online teaching strategies are vital. Current anatomy curriculum at Paul L. Foster School of Medicine consists of self-taught PowerPoint material, clinical vignette-centered team-based learning (dry lab), and prosection-based instruction (wet lab). This study examined the impact of video-based muscle model (VBMM) instruction using a student-designed forearm muscle model on anatomy quiz scores and student perceptions of its effectiveness with regards to learning outcomes. METHODS Students divided into Group 1 (54 students) and Group 2 (53 students) were assessed prior to and following a 3.5-minute video on anterior forearm compartment musculature using the muscle model. Group 1 began by completing a pretest, then received VBMM instruction, and then completed a posttest prior to participating in the standard dry lab and 1 hour wet lab. Group 2 completed the wet lab, then received the pretest, VBMM instruction, and posttest prior to participating in the dry lab. Both groups took an identical five-question quiz covering locations and functions of various anterior forearm muscles each time. RESULTS Mean scores were higher than no formal intervention with exposure to VBMM instruction alone (0.73 points, P = .01), wet lab alone (0.88 points, P = .002), and wet lab plus VBMM instruction (1.35 points, P= <.001). No significant difference in scores was found between instruction with VBMM versus wet lab alone (P = 1.00), or between either instruction method alone compared to a combination of the two methods (P = .34, .09). Student survey opinions on the VBMM instruction method were positive. CONCLUSION VBMM instruction is comparable to prosection-based lab with regards to score outcomes and was well received by students as both an independent learning tool and as a supplement to cadaveric lab. When compared to either instruction method alone, the supplementation of VBMM with cadaveric prosection instruction was best. VBMM instruction may be valuable for institutions without access to cadaveric specimens, or those looking to supplement their current anatomy curriculum.
How diverse is hotel website accessibility? A study in the central region of Portugal using web diagnostic tools

Accessible tourism is a very important growth market that should not be ignored by the tourism industry, not only due to legal obligations and social responsibility but also because of business opportunities. However, people with special needs face various constraints in accessing tourism products. The absence of accessible information is one of the main barriers that people with special needs face when they intend to travel. The Internet represents one of the most important information sources in tourism. However, a limited number of studies examine the use of the Internet in the accessible tourism market, specifically website accessibility. To extend knowledge in this field, this study aims to analyse the website accessibility of hotels and Pousadas de Portugal located in the Central Region of Portugal. A sample of 306 websites was analysed based on Web Content Accessibility Guidelines (WCAG) 2.0, using automatic web diagnostic tools (AccessMonitor and TAW). This analysis was performed considering the A, AA and AAA conformance levels of WCAG. Findings reveal that the web accessibility level of the hotels analysed is low, with the ‘Perceivable’ and ‘Robust’ guidelines being the most critical. Moreover, there are differences in the web accessibility levels in terms of hotel category. Contrary to what was expected, the higher category hotels present the lowest level of web accessibility. These results can help hotel managers and web designers to improve communication with an important growth market – accessible tourism.
Effect of Harvest Time and Fruit Firmness on Red Drupelet Reversion in Blackberry

Red drupelet reversion (RDR) is a postharvest disorder of blackberries (Rubus L. subgenus Rubus Watson) in which fully black drupelets revert to red after harvest. This disorder can negatively impact consumer perception of fresh-market blackberries. The cause of RDR is hypothesized to be related to intracellular damage sustained because of mechanical and environmental stress during and after harvest. Cultivars differ in susceptibility to this disorder; and cultural factors, including nitrogen rate, harvest and shipping practices, and climate during harvest, influence RDR severity. In this 2-year study, seven genotypes (cultivars and advanced selections) developed in the University of Arkansas System Division of Agriculture (UA) blackberry breeding program, with a range of fruit textures, were evaluated to determine whether firmness was correlated with RDR. In addition, fruit was harvested at four different times (7:00 am, 10:00 am, 1:00 pm, and 4:00 pm) to investigate whether harvest time influences RDR. All seven genotypes were harvested at the four times on two harvest dates per year and evaluated for RDR and firmness after 1 week of cold storage (5 °C). Fruit harvested early in the day had less RDR, with 7:00 am harvests having the least RDR in both years. Significant genotypic differences in RDR and fruit firmness were found in each year. Firmness was negatively correlated with RDR in 2018 and 2019. These results indicate that growers may be able to reduce the prevalence of RDR by choosing cultivars with firm fruit texture and harvesting early in the day.
Low-Powered Photodetector Based on Two-Dimensional InS0.3Se0.7/WS2 Heterostructure

Photodetectors based on two-dimensional (2D) materials have great potential applications in the field of new energy, such as fuel cells, solar cells, and other fields. Van der Waals (vdW) heterojunction photodiodes are expected to be one of the promising applications of two-dimensional materials due to the photoelectric properties without consideration of lattice mismatch. High-efficiency photoelectric sensors based on two-dimensional materials have great significance to reducing the energy consumption of devices. Here, we build a complex vdW heterostructure by combining InS0.3Se0. 7 with another suitable 2D material WS2. Few-layer graphite was used as electrodes to enhance the optoelectronic performance of indium monochalcogenides. Evident photocurrent is observed in the InS0.3Se0. 7/WS2 vdW heterostructure device arising from the formed p–n junction at the interface. The uniformity and photoresponse of the InS0.3Se0. 7/WS2 vdW heterostructure has been further investigated by the photocurrent mapping. It shows that the entire photovoltaic current was originated from the InS0.3Se0. 7/WS2 vdW heterojunction by scanning photocurrent microscope images. Furthermore, the response speed is enhanced at small bias voltage. The transient photoresponse can be well reproduced in almost 100 cycles, indicating the good repeatable optoelectronic performance. Our study indicates that the as-prepared InS0.3Se0. 7/WS2 vdW heterostructures are attractive building blocks for photodetectors application. Our findings will open up a new way to further develop high-performance, low-power, and energy-efficient photodetectors based on indium monochalcogenides.
Exploring Children’s Values Questionnaire: Measurement, Gender, and Age Issues

Values are conceptualized as the standards individuals use to determine the status of events and actions and are considered to influence individuals’ behaviours, reasoning, and perceptions. Based on a synthesis of six school-based student values enhancement programs, this paper reports on the development of the Children’s Values Questionnaire (CVQ). This Questionnaire was conceptualized as composing of seven dimensions: Self-Concept; Behaviour; Healthy Life; Social; School Climate; Emotional Intelligence; World View and 26 related sub-dimensions. A total of 848 co-educational students (52% male, 48% female) from Years (Grades) 4 to 7, ages 9 to 13+ years, across 11 Australian schools completed the 95-item CVQ Questionnaire. The Cronbach alpha coefficient of the instrument was 0.94, indicating that the questionnaire had good internal consistency. The inter-correlation between its seven dimensions clustered at Pearson r = 0.55. An exploratory factor analysis was supportive of the CVQ’s theoretical construct (Norm Fit Index of the data to the theoretical construct, 0.09). Girls rated themselves higher than boys (p < 0.001) on items related to Playing by the Rules, Responsibility, Creativity, Empathy, and Communication, and boys rated themselves higher than girls on Physical Activities items (p < 0.001). Older students (Years 6 and 7) compared to younger students (Years 4 and 5) demonstrated greater discernment and differentiation of context (p < 0.05), the growing influence of peer friendship in their value beliefs and an increase in confidence in social settings (p < 0.001). The relationship of the CVQ to Schwartz’s Universal Valued Goals is reported in the paper, along with examples of the application of the CVQ in schools.
Disain dan Validitas E-Modul Interaktif Berbasis Konflik Kognitif untuk Remediasi Miskonsepsi Siswa pada Konsep Gaya

Student misconceptions occur because students build their own concepts from their own environment without the help of experts, therefore, students' initial knowledge that is not the same as expert opinion is what causes misconceptions. This study aims to produce an interactive conflict-based cognitive e-module to remediate misconceptions and improve students' understanding of concepts about force. This type of research is design or development research using the Plomp model, with 3 phases, namely; (1) preliminary research, (2) development phase and (3) assessment phase. This research is limited to the expert review development phase. The preliminary research was conducted by reviewing 5 journals about the problems of students' misconceptions on the concept of force. At the development phase, e-module design, self-evaluation, and expert review of the e-module prototype are carried out. The data were obtained from the self-evaluation assessment sheet by three researchers and the validation sheet by three physics lecturers. Based on the preliminary research, it was found that there were problems in understanding the concept of students in the material of force. Therefore, a cognitive conflict-based emodule was designed that could improve students' conceptual understanding. The self-evaluation results of the emodule design showed that the e-module design was in the very good category with an average of 93.4. The results of the expert's study showed that the e-module design was in a very valid category with an average of 85.6.
Evaluation of the Steam Explosion Pretreatment Upon the Anaerobic Digestion of Water Hyacinth Biomass: Influence on Liquid and Solid Fractions

Biochemical methane potential tests were performed to evaluate the effects of steam explosion on the liquid and solid substrates of thermal hydrolysis pretreatment applied to water hyacinth biomass. The operational conditions of the thermal hydrolysis applied the combination of two temperatures (170 and 210 oC) and two cooking times (5 and 30 min). The higher solubilization factor was 22.9% for the sample pretreated at 210 oC and 30 min followed by steam explosion effect (TH + SE). Steam explosion, temperature and time were, in order of importance, the more effective operational conditions for the biomass solubilization. The sample 210 oC - 5 min TH + SE presented the higher methane production increase, in relation to the raw substrate, resulting in a increment factor of 2.43, for the solid sample. The higher methane production increase for the liquid sample was on a factor of 1.67, for sample 210 oC - 30 min TH + SE. The higher biomethanization increase considering both biomass factors (solid + liquid) was obtained for the pretreatment 170 oC - 30 min TH + SE. A combined model confirmed the hydrolysis limitation for the solid samples biodegradation; however, it was not clear for the prediction on the liquid samples. Micrographs evidenced the morphological changes of the solid substrate with the solubilization increase. Particle size reduction was the most effective effect of the pretreatment on the substrate morphology. Porosity increment was observed only in the surface of the sample 210 oC - 30 min TH + SE.
The Evolution of Internal Auditing at a Central Bank: The Maltese Experience

Purpose: The main objectives of this article are to assess how the governance and operational structures that constitute the internal Audit Function (IAF) of the Central Bank of Malta (CBM), have evolved and grown over the years. Design/Methodology/Approach: This study adopted a qualitative, mixed-method approach to ascertain the achievement of these objectives. Semi-structured interviews were carried out with six major players who, to varying degrees, acted as catalysts fuelling such evolution. The selection encompassed both current and ex-IAF officials deployed in various hierarchical positions. These interviews were then backed by an analysis of the CBM Annual Reports and any available unpublished internal audit documentation. Findings: The findings indicate that the core objectives of the IAF remained, in essence, unchanged over the years except for being broadened to enhance organisational value, to meet increasing client expectations and closely align with developments in the profession. As a result, stakeholder perceptions of the IAF improved from being negative and invasive to becoming generally respectful and appreciative. Practical Implications: Audits had to decrease in number over the years as most audits had become considerably more complex and therefore more labour intensive and time-consuming. Staff turnover decreased when more emphasis was placed on staff development, training and career management. Originality/value: The vicissitudes of the IAF history to date, particularly the major historical milestones found to have spurred the various stages in the IAF evolution, may also prove insightful for the IAFs of other financial institutions.
Reassessing species boundaries in the Syagrus glaucescens complex (Arecaceae) using leaf anatomy

The Syagrus glaucescens complex comprises three species: Syagrus glaucescens Glaz. ex Becc. , Syagrus duartei Glassman, and Syagrus evansiana Noblick. Recently, a new population of S. evansiana that possesses a high degree of endemism was reported in the Serra do Cabral mountain. Here we intend to study the leaf anatomy of the S. glaucescens complex and confirm whether this newly found population (from now on called Syagrus aff. evansiana) belongs to S. evansiana or not. Specimens were collected to investigate their leaf anatomy, which showed distinct differences between S. aff. evansiana and S. evansiana. The midrib anatomy revealed novelties for the S. glauscecens complex, proving useful for species diagnosis. Features such as accessory vascular bundles around the vascular system of the midrib and the number of collateral bundles are diagnostic for species identification. In addition, morphological and anatomical analyses indicated a correlation with the species occurrence. We found greater similarity between S. glaucescens and S. duartei, while S. evansiana and S. aff. evansiana are more alike. Here, we propose a new identification key based only on the leaf anatomy. Despite their morphological similarities, S. aff. evansiana and S. evansiana presented differences in leaf anatomy, which — when associated with their geographical isolation — suggests a fourth taxon in the complex.

Validation of a new patient-reported outcome measure of balance recovery confidence (BRC) for community-dwelling older adults: a study protocol

Abstract Background Patient-reported outcome measures (PROMs) provide clinicians a greater understanding of patients’ perceived ability in their physical performance. Existing PROMs on falls efficacy provide meaningful information about the perceived ability in older people to perform common activities of daily living without falling. However, the perceived ability to recover balance from a slip, a trip, or volitional movements has been inadequately assessed. Balance recovery confidence relates to the judgment of self-reactive ability. The scale of balance recovery confidence (BRC) is a new PROM that measures perceived balance recovery self-efficacy. The purpose of the study protocol is to describe the first psychometric evaluation of BRC’s measurement properties. Objective This study is a validation phase of a newly developed PROM conducted in Singapore. Methods Two hundred community-dwelling older adults, aged 65 years and older, will complete five self-reported instruments (BRC, Activities-specific Balance Confidence Scale, Falls Efficacy Scale-International, Late-Life Function and Disability Instrument-Function and Global Perceived Effect) and three performance measures (Hand strength dynamometer, 30-second Chair Stand, Mini BESTest). Classical test theory methods will assess acceptability, data completeness, targeting of the items, scaling assumptions, internal consistency reliability and construct validity. Factor analysis will establish unidimensionality. Rasch analysis will evaluate item fit, differential item functioning, response scale ordering, targeting of persons and items and the reliability. Results The findings from this study will be published in peer-reviewed journals and presented at national and international conferences in rehabilitation-specific context. Conclusions This is the first validation study of BRC. The study will give confidence among clinicians and researchers to use the BRC in fall management research and clinical practice.
