Mental disorders lead to difficulties in social, occupational and marital relations. Failure to detect mental disorder denies patients potentially effective treatment. This study aimed to assess the prevalence and nature of mental disorders at the primary care settings and the recognition of these disorders by the attending physicians. Over a period of eight weeks, consecutive and consenting patients who attended three randomly selected primary health care facilities in Sagamu Local Government Area of Ogun state were recruited and administered a questionnaire that included a socio-demographic section and Patient Health Questionnaire (PHQ). A total of 412 subjects took part in the study. Subject age ranged from 18-90 years with a mean age of 52.50±21.08 years. One hundred and seventy-six (42.7%) of the subjects were males. A total of 120 (29.1%) of the subjects had depressive disorder, 100 (24.3%) had anxiety disorder, 196 (47.6%) somatoform disorder and 104 (25.2%) met the criteria for an alcohol related problem. The PHC physicians were only able to diagnose disorders relating to mental health in 52 (12.6%) of the subjects. Health and work situations accounted for more than three-quarters of the causes of stress experienced by the subjects. We conclude that there is a high prevalence of mental disorders among patients seen in primary care settings and that a significant proportion of them are not recognized by the primary care physicians. Stress relating to health, work and financial problems is common among primary health care attendees. Physicians in primary health care should be alert to the possibility and the impact of undetected psychiatric morbidity.

This study aims to examine the role of libraries in stimulating access to information concerning environmental justice issues. This study also provides valuable insights into libraries’ contributions to addressing environmental justice concerns and informs strategies for maximizing their impact in this critical area.

In conducting this study the role of academic librarians at the Federal University of Technology Ikot Abasi, Akwa Ibom State, Nigeria, using a descriptive design and qualitative research method. The population for this study consists of academic librarians who were chosen due to their expertise in information access and their potential impact on environmental justice initiatives within the academic community. Data were collected through focus group discussions with the participating academic librarians.

The findings of this study underscore the critical role of addressing information disparities within the context of environmental justice, emphasizing the transformative potential of information access in empowering communities. The analysis reveals a consensus among respondents regarding the multifaceted role of librarians in addressing environmental justice. Librarians are perceived not only as information custodians but also as active contributors to community engagement, awareness and social change. This study identifies both challenges and opportunities for libraries to enhance awareness of environmental justice issues among their patrons. While existing resources related to environmental justice in the library’s collection are generally viewed positively, there is consensus among participants that there is room for improvement. Finally, this study acknowledges gaps in the current collection regarding information on environmental justice. It underscores the need for up-to-date multimedia resources focusing on local issues and representing diverse perspectives.

Collaboration with scholars from diverse fields such as environmental science, sociology and public policy could enrich the understanding of the complex intersections between information access, environmental justice and librarianship.

Librarians have a responsibility to promote information access and environmental justice by curating relevant resources, promoting information literacy, engaging with communities, advocating for change, addressing digital access and equity issues, fostering cultural competence and collaborating with other stakeholders.

This study presents a compelling and forward-thinking perspective that underscores the critical role of librarians in addressing environmental challenges and fostering social equity.

As one of the buzzwords in the present age with considerable impacts in tertiary institutions, social media use in online teaching, learning and information dissemination have been extensively discussed in extant literature. This paper aims to explore the existing campus sustainability appraisal (CSA) tools to identify the length at which social media has been used, especially in environmental sustainability indicators’ selection and empirical verification.

The methodology is mainly based on a desktop study involving comprehensive review and content analysis of existing CSA tools’ documents. Webpage content analysis of selected sustainability monitoring and tracking system in higher education institutions was also conducted.

The tools' content analysis reveals insufficient utilization of social media data and platforms in campus sustainability environmental-dimension indicators selection. To bridge this identified research gap, social media user-generated content for appraising the campus-wide environmental sustainability indicators preference in tertiary institutions was proposed.

The adoption and modification of this study’s proposed approach by tertiary institutions, especially in sub-Saharan African countries, could help address most campus-wide environmental challenges raised, commented on and discussed on social media.

This study contributes to knowledge gaps by revealing the extent of social media utilization in extant tools. With the expanding utilization of different social media platforms by various tertiary institutions worldwide, their administrators' responsibility is to put these social media data into fair use.

This study investigates building information modelling (BIM) penetration in quantity surveying (QS) practice by examining the significance attached to the benefits and barriers of BIM adoption, BIM capabilities and future directions of BIM in QS processes. A popular opinion amongst construction researchers is that BIM has the capacity to revolutionize the industry. The study draws-out information in the literature regarding discipline-specific penetration of BIM.

Snowball sampling method was used to obtain information through a survey questionnaire. A total of 73 participants, largely quantity surveyors in Western Australia, took part in the study. Reductionist methodology was used to identify key variables of QS-BIM competencies that are most significant statistically.

BIM does not impose additional difficulties to traditional QS processes. Adherence to standard method of measurement and limited market demand do not hinder BIM deployment significantly. Quantity surveyors are able to use BIM to support their professional services once definitive design models are involved. In addition, the study identifies BIM penetration barriers to include constraints caused by centralised database management and interoperability issues, limitations imposed by market drivers, lack of in-house expertise to manage modelling needs and limited capability in software management.

Future opportunities for skill development are in the areas noted in the findings. Whilst many studies have reported resistance and widespread scepticism amongst some construction disciplines regarding BIM adoption, this study finds BIM penetration in QS practice is considerable, a direction that could trigger further novel innovations.

The methodology reported in the study is novel. In addition, findings from the study inspires other discipline-specific studies to articulate their BIM-penetration trends so that t broad areas of construction can develop a balanced strategy around BIM and innovation development.

A section of project management literature attributes overruns to estimators’ deceit and delusion. An example of this is Flyvbjerg’s theorisation of strategic misrepresentation and optimism bias. To show that such a notion is not true entirely, the study elicits evidence relating to how costs of projects often fluctuate erratically as prices of construction materials change throughout contract cycle times. The purpose of this paper is to examine the causal relationships between persistent changes in prices of construction materials and project’s outturn costs.

The authors obtained and analysed price data of construction materials published in a Nigerian national daily in the 16 years between 2000 and 2015. Additional data were obtained from a quantity surveying firm to validate the archival data on material prices, and to compare the firm’s robust database of project estimates and the corresponding outturn costs of specific building elements (detailed in the study). The goal of the analysis is to explore spontaneity and causal impact in the relationship between changes in prices of construction materials and project costs. Kolmogorov-Smirnov and Anderson-Darling tests were used to obtain the probability distributions of the causal relationships.

Findings show disproportionate positive correlations between changes in material prices and outturn costs in Nigeria. An important dimension to this, however, is that although fluctuations in material costs often trigger variations to project costs, outturn price only accounts for about one-third of actual cost variability. Recovery of costs, not least profit making, under these conditions is a complex process.

This paper concludes that dynamism in cost attributes is neither a deceit nor a delusion; understanding and tolerating them is not a systemic weakness, rather an essential key to project success and stakeholder satisfaction. Findings from the study also bring measured certainties to the transformation of variable costs into fixed price outcomes, an important consideration that will help contract estimators and project managers to understand the likelihood of fluctuation in material costs and how these might trigger variability in project costs.

Painting of buildings predates civilization. The primary purpose was to add beauty or aesthetics to the built environment. It was also to showcase the level of civilization, taste and fashion drive of the people. However, modern findings have proved that paint (when applied as a finishing coat on buildings) can elongate the service life of such buildings due to some characteristic properties it contains and modern additives that are included at production stage. This paper aims to examine some of the properties inherent in paint through which resistance to failure and better performance is enhanced, aesthetics is maintained and maintenance is reduced. It also examines whether these qualities subsist in all environments. Particular attention is given to its resistance to the impact of saline air when used around the Atlantic Ocean.

The research adopted a qualitative and quantitative approach with empirical analysis in examining the performance of paint used in salt laden environment.

It shows that paint used in an environment where saline air and salt is prevalent begins to deteriorate after two years and requires repainting as against the established norm of five to seven years (5‐7) in areas that are not exposed to saline air. The impact of saline air is significant at p<0.01.

Maximum life span of current paint products in the area is determined to provide adequate information for the preparation of maintenance schedule for painted exterior. Paint with higher resistance to salt attack is required to enhance the longevity of painted exterior in areas at close proximity to sources of salt. Specifying current available paint for exterior finish will be uneconomical and non‐compatible with the principle of sustainability.

The authors made a fresh attempt at investigating the life's span of paint used as exterior finish in salt laden area around the Atlantic Ocean due to the peculiarity of the stresses of the tropical region on external finishes. It also compared the result with existing researches. Differences in paint performance are established.

The popularity of Building Information Modelling (BIM) has improved tremendously in recent years. The business sense it makes to construction small to medium‐sized (SME) organizations has also become vitally important, especially when the deliverables of BIM potentials are becoming more explicit than they were several years ago. Moreover, there is adequate evidence to suggest that an early adoption of BIM by construction SME organizations could mean marked sustainable business advantage to them. The purpose of this paper is to initiate a long‐term study on how BIM triggers market improvements in the Australian construction industry, to establish the specific impact of these on construction industry's contribution to Australian economy, also to develop a simple model on the cost of implementing BIM in a typical construction SME.

This research relies on evidence from literature to identify different operational models of construction organizations, namely; matrix, divisional, functional and networked business models. A definite approach was taken to articulate some contributory concepts and rationales which drive organizational response to technological changes across the identified four categories of organization structure models. Focus group discussion was the primary research method for this study, while additional data were collected from public sources. Respondents and data were sourced from two firms selected from each type of organization model. In the end, 24 industry practitioners from a range of Australian construction SME businesses that provide software and technical support services, consultancy and contracting services took part in the study.

Analysis of 32 sample cases revealed that BIM implementation costs were mostly defined by a range of cost variables, including software acquisition and technical support, hardware, training, services and implementation contingencies. On the average, software costs accounted for about 55 percent of total implementation costs. This particular cost descriptor was about five to seven times more than the cost of hardware (depending on the level of sophistication of operations, expected implementation outcomes and whether new hardware were used or existing installation were upgraded with BIM compliant drivers). The study also found that training cost was a third of software costs, while the average total cost of services, recruitment and contingencies, all added together, was about 5 percent of total implementation costs. In the end, a linear model was developed to predict the cost of BIM implementation in construction SMEs.

A preliminary version of this study has been presented in the 2010 edition of the International Conference on Information Technology in Construction (CIB W078). As a study in a new direction, it focuses on specific organization models and their unique responses to drivers of change. While other studies have looked into macro implementation of BIM, mostly without considering the peculiarity and dynamics of organization structure, this study has focused on construction SME businesses offering a wide range of services.

The purpose of this study is to evaluate the quality and sensory properties of cookies produced from wheat flour using avocado puree as fat substitute.

Cookies were produced from wheat flour using avocado puree as fat substitute in ratio 0%, 25%, 50%, 75% and 100%, respectively. The formulation of margarine and avocado puree blends was done by using D-Optimal Mixture Design. In all, 20 samples were produced from each substitution level and analyses were done in triplicates to obtain mean values using standard methods. Means were separated by Duncan’s multiple range test, and significances were accepted at less than 5% confidence level (p < 0.05). Proximate and functional analyses were conducted on the flour samples, while cookie samples were subjected to proximate and sensory analyses.

The results of this study revealed that the values of loose bulk density, packed bulk density, oil absorption density, water absorption capacity, swelling power, solubility and dispersibility of the flours at p < 0.05 are 0.3–0.4 g/ml, 0.5–0.7 g/ml, 16.9%–94.0%, 39.7%–80.6%, 461.2%–618.2%, 6.0%–29.8% and 69.0%–82.8%, respectively. The moisture, protein, fat, total dietary fiber, total ash and carbohydrate contents of the cookies at p < 0.05 are 3.6%–16.7%, 6.5%–9.9%, 2.5%–19.2%, 1.7%–1.9%, 1.1%–3.0% and 65.0%–70.7%, respectively. The taste, color, crispiness, texture and overall acceptability of the cookies at p < 0.05 are 7.4–7.8, 6.9–7.5, 7.2–7.9, 7.3–7.7 and 7.4–8.3, respectively. The sensory scores showed that panelists preferred the taste, crispiness and texture of the cookies produced from wheat flour using avocado puree as fat substitute at varying proportion. The sensory characteristics of sample WF⁴ (100% avocado puree) were rated overall best in all the parameters tested followed by sample WF³ (75% avocado puree). Hence, this study established the possibility of producing cookies from wheat flour using avocado puree as fat substitute without a negative impact on the sensory characteristics and the consumers’ acceptability.

The cookies produced from this study are not meant for vegetarians because eggs were added in the formulations and recipes but could be valuable to ovo-vegetarians that may take food with eggs without restriction. The major challenge of this study was that avocados are very expensive in much of the world, so this is only suitable and viable where there is an excess of the fruit.

This study examined the use of avocado puree as fat substitute in cookie production. Effects of avocado puree on proximate composition and functionality of cookies produced from wheat flour were also determined. This approach was novel, and it will encourage the use of avocado for value-added in industrial food production.

Edible insects are considered as a novel food in western countries, with their introduction to cuisine having to overcome major barriers, such as disgust. The studies related to acceptance of entomophagy have exponentially grown since 2015. However, such studies generally focus on people older than 18 years old. The purpose of this study is to assess the perceptions of youngsters towards edible insects.

A survey associated with an optional tasting session was conducted to record opinion of 151 youngsters in Belgium (9–17-year-olds).

Many respondents are acquainted with entomophagy and had already eaten insect-based food. Most youngsters associated insects as snacks and salty foods, and they agreed to consume processed insects (falafel) during the tasting session. Tasters had to evaluate the falafel, and higher ratings were recorded in male respondents, as highlighted in studies including adults. More negative evaluations would be expected among older respondents if unprocessed insects were served, as they were more willing to consume processed insects than entire insects. Finally, attitudes towards entomophagy evolved positively after the tasting session. Such events are consequently recommended to promote entomophagy across western youngsters.

Few studies explored the attitude of western youngsters towards entomophagy. This paper aims to fill this gap by focusing on this young component of the Belgian population.

The purpose of this paper is to target on individual perceptions of BIM practice in terms of BIM benefits, critical success factors (CSFs) and challenges in Chongqing which represented the less BIM-developed metropolitan cities in China.

Adopting a questionnaire-survey approach followed by statistical analysis, the study further divided the survey population from Chongqing into subgroups according to their employer types and organization sizes. A further subgroup analysis adopting statistical approach was conducted to investigate the effects of employer type and organization size on individual perceptions.

Subgroup analysis revealed that governmental employees held more conservative and neutral perceptions toward several items in BIM benefit, CSFs and challenges. It was inferred that smaller organizations with fewer than 100 full-time employees perceived more benefits of BIM in recruiting and retaining employees, and considered more critical of involving companies with BIM knowledge in their projects.

This study contributed to the body of knowledge in managerial BIM in terms that: it extended the research of individual perceptions toward BIM implementation by focusing on less BIM-mature regions; it contributed to previous studies of influencing factors to BIM practice-based perceptions by introducing factors related to organization type and sizes; and it would lead to future research in establishing BIM climate and culture which address perceptions and behaviors in BIM adoption at both individual and organizational levels.
