The purpose of this paper is to report the outcome of a city‐wide survey of teenagers’ views on their health, and compare this with the outcomes of a science‐oriented health intervention called LifeLab, a hospital‐based classroom aimed at developing teenagers’ attitudes towards their health and that of their future children.

A questionnaire survey of 597 14‐year olds across the city of Southampton was conducted to gauge their views and behaviour in relation to their own health. The views of 37 students who took part in innovative, hospital‐based, hands‐on LifeLab activities were compared with those of their peers six months after the intervention to analyse long‐term impacts of the experience. Interviews were carried out with ten LifeLab students to gain further insights.

The intervention created a wider appreciation among students that food they eat now could affect their long‐term health and the health of their future children. Students became significantly more interested in studying science beyond compulsory schooling, and in considering science and healthcare career options.

Although results were statistically significant, the intervention sample was quite small, and further data collection is ongoing. The city‐wide student response rate of 29 per cent was fairly low.

This study has shown that a carefully structured hospital‐based classroom visit, and associated science lessons can have a marked effect on student engagement with health‐related issues, and an impact on their consideration of their career choices.

The hospital‐based classroom is an innovative approach to improving teenagers’ knowledge and attitudes towards their health. The paper's findings should be of interest to a range of educational stakeholders including teachers, local education authorities and local politicians concerned with health education matters.

The purpose of this paper is to examine the medium‐term tenure option, in capital valuation terms, through an empirical study of 232 households in 39 tenement properties in Barkinsalle and Saukakahuta, two neighborhoods of Minna, Nigeria widely associated with poor households.

An empirical approach was used. Data were obtained through questionnaires from six real estate firms and 232 households in the study area. The tenancy statuses, rental values, contract rents, terms and durations of tenancies were some of the data elicited.

Using contemporary valuation techniques it was affirmed that a typical medium‐term lease from 2009 to 2018 would produce substantial capital value between N59,000.00 (US$393.33) and N90,000.00 (US$600.00).

This research is limited only to cases where profit rent advantages are clearly established. The institutional settings needed to sustain leasehold profit rents have to be identified.

Tenants need valuation advice on medium‐term leasehold rights with promises of profit rent advantages. There is need to sensitize both landlords and tenants as to the mutual benefits.

Properly harnessed, the capital value amount could support access to micro‐credit, an essential tool for sustainable fight against urban poverty, through some established financial institutions and special public agencies in Nigeria.

No previous study of Minna had verified, quantitatively and empirically, that medium‐term leases under the parameters empirically specified in the paper would produce such substantial capital values.

The rising concern for the accuracy of residential valuations in Nigeria has created the need for key stakeholders in the residential property markets in the study areas to know the level of accuracy of valuations in order to make rational residential property transactions, amongst other purposes.

A blend of descriptive and causal designs was adopted for the study. Data were collected via structured questionnaire administered to 179 estate surveying and valuation (ESV) firms in the study areas using census sampling technique. Analytical techniques such as median percentage error (PE), mean and relative importance index (RII) analysis were employed in the analysis of data collected for the study.

The study found that valuation accuracy is greater in the residential property market in Abuja than in Minna, with inappropriate valuation methodology as the most significant cause of valuation inaccuracy.

The practical implication of this study is that a reliable databank should be established for the property market to provide credible transaction data for valuers to conduct accurate valuations in these cities. Strict enforcement of national and international valuation standards by the regulatory authorities as well as retraining of valuers on appropriate application of valuation approaches and methods are the recommended corrective measures.

No study has comparatively examined the accuracy of valuations in two extremely different residential property markets in the country using actual valuation and transaction prices.

Research in tourism and hospitality industry marketing has identified many highly effective applications of social media. However, studies in the existing literature do not enable a comprehensive understanding of this phenomenon because they lack a theoretical foundation. Therefore, this study systematically reviewed the literature from the perspective of the task-technology fit (TTF) theory. The purpose of this paper is to map out what is known about social media use in tourism and hospitality marketing and what areas need further exploration.

A descriptive cumulative review of the literature obtained 99 articles published in tourism and hospitality journals from 2010 to 2019.

The analysis suggests that to understand social media use in tourism marketing, researchers and practitioners in the industry must clarify the following four issues: the control variables, longitudinal analyzes and TTF concepts that should be used in future studies; the fitness of social media platforms for tourism marketing; how various social media platforms differ in terms of performance outcome; and the digital divide in the use of social media for tourism.

An integrated framework was developed to identify constructs and to understand their relationships. Recent studies in this domain are discussed; theoretical and practical suggestions and implications for future research are given.

This study aims to empirically validate an innovative work behaviour-enhancing model of employability in small- and medium-sized enterprises (SMEs), and to examine possible moderating effects of age.

Data have been collected from 487 pairs of employees and their immediate supervisors who worked in 151 SMEs. Structural equation modelling (SEM) has been used to investigate the predictive validity of employability on innovative work behaviour using a multi-source approach. The moderating effect of employee age on the relationship between, on the one hand, self-ratings and supervisor ratings of employability, and, on the other hand, innovative work behaviour has been tested using multi-group SEM.

Results suggest that self-rated employability correlates positively with supervisor-rated innovative work behaviour, and that supervisor-rated employability correlates positively with self-rated innovative work behaviour. Age appeared to have a weak influence on the relationship between employability and innovative work behaviour; more specifically, in case of a higher age, the relationship was stronger.

The cross-sectional design is a limitation of this study. Another limitation relates to the generalizability of the study findings outside the context in which the research has been undertaken. The relational meaning of employee age might be different in other cultures.

Supervisors appear to play an essential role in providing an age-friendly working life for employees. Moreover, as SMEs often do not employ professionals to manage human resources, supervisors themselves have to carry the responsibility to encourage aging employees to develop themselves the enhancing innovative work behaviour.

This study is the first to investigate the predictive validity of employability on innovative work behaviour and the effects of age on this relationship.

The purpose of this paper is to shed new light on carrying out “at-home” ethnography by building and extending the notion of roles as boundary objects, and to elucidate how evolving roles mediate professional identity work of the ethnographer.

In order to theorize about how professional identities and identity work play out in “at-home” ethnography, the study builds on the notion of roles as boundary objects constructed in interaction between knowledge domains. The study is based on two ethnographic research projects carried out by high-level career switchers – corporate executives who conducted research in their own organizations and eventually left to work in academia.

The paper contends that the interaction between the corporate world and academia gives rise to specific yet intertwined roles; and that the meanings attached to these roles and role transitions shape the way ethnographers work on their professional identities.

These findings have implications for organizational ethnography where the researcher’s identity work should receive more attention in relation to fieldwork, headwork, and textwork.

The study builds on and extends the notion of roles as boundary objects and as triggers of identity work in the context of “at-home” ethnographic research work, and sheds light on the way researchers continuously contest and renegotiate meanings for both domains, and move from one role to another while doing so.

Non-value adding activities or waste have been a major challenge for the construction industry. Researchers worldwide have investigated how such activities can be reduced or overcome in the industry. However, much has not been done regarding waste in the production process of building blocks. Therefore, this study aims to investigate the various waste in sandcrete blocks production process (SBPP). The study also aims to find out the causes of the waste and their impacts on the factory performance.

To achieve the aims of this study, a qualitative study was conducted in five sandcrete blocks firms in Minna. Physical observation and interviews were the main instruments used for data collection. The data obtained were analyzed through content analysis. Samples of blocks (low standard only) were also taken to the laboratory for compressive and porosity tests. Thereafter, questionnaires were administered to other sandcrete blocks producers in six firms. The essence of this was to investigate the applicability of the identified waste in other factories in the study context and for further data analysis.

Typical forms of waste in SBPP are excessive stocking of sand and cement, long distance covered from the store to the mixing or production location, excessive quantity or over design of materials and over vibration or compaction of the newly produced blocks. It is anticipated that adoption of lean concepts, tools and techniques in the production of sandcrete blocks will help to eradicate the identified waste in the process and stimulate a future state value stream mapping (VSM). The practicality of the expected future state VSM is presently being investigated by one of the five firms in the study context.

The findings of the study mainly provide further insights on the various process waste in Nigerian sandcrete blocks production.

The study provides knowledge on how lean thinking can be adopted to identify and reduce waste in SBPP. Such knowledge may be beneficial to the present and prospective sandcrete blocks producers. The study also provides insight on how the overall cost of production of sandcrete blocks and the quantity of CO₂ that is being released into the atmosphere in the production process can be reduced. The VSM in the proposed framework also serves as a tool that can be globally adopted for waste identification by producers of other forms of blocks such as bricks.

This paper satisfies all the tenets of originality as it has not been previously published and all the information obtained from other studies have been duly referenced. The study is also original as it is first in the study context to propose for a lean framework that can be used to reduce waste in SBPP.

Construction process is complex and traditionally fragmented; thus, it is almost impossible to have a project completed without changes to the original plan or the construction process. The purpose of this study is to identify and examine the causes of variation orders, ascertain their effects and establish the cost and time performance implication as a result of variation orders.

This study obtained information from 90 construction stakeholders on 30 completed educational building projects to ascertain the causes and effects of variation orders on project delivery using questionnaire survey. In addition to this, a pro forma document was designed to obtain the project characteristics, cost and time data from these 30 completed educational building projects. Factor analysis was used to categorise the causes of variation orders, while severity index was used to examine their effects on project delivery. The hypothesised statement was tested using paired t-statistics to examine whether a statistically significant difference existed between variation orders, cost and time performance of the projects.

The study identified 13 main factors as causes of variation orders and the results revealed that the most frequent effects of variations were increase in construction costs, time, client dissatisfaction, increase construction project rework and demolition and project abandonment. The results also showed that variation orders had significant effects on both cost and scheduled performance of the educational building projects with average cost and time escalation of 33.95 and 29.45 per cent of the original project cost and time, respectively, for the entire projects studied, while average cost implication of variation orders is 23.79 per cent.

The findings in this study will be of assistance to government agencies and management of public works in higher institutions of learning in managing variations in construction projects. The study will also add to the current literature on the impact of variation orders on educational building projects in developing countries. Finally, it will create the much-needed awareness on the severity and implication of change or variation orders on project delivery.

The study identified and examined the causes of variation orders, ascertained their effects and established the cost and time effects of the causes of variation order on project performance. This will assist project initiators, contractors, consultants and other stakeholders to fully appreciate and understand the significant effects of variation orders on project performance.

The purpose of this paper is to examine the factors affecting the academic outcome of real estate students in a specialized Federal University in Nigeria. Furthermore, this paper investigates the phenomenon of publication bias in the extant literature as such evidence poses severe threats to the validity of empirical findings on factors affecting the degree outcome of undergraduate students.

The standard statistical approach adopted was to examine whether the reported coefficient estimates from ten empirical studies (105 observations) are independent of their standard errors by employing both ordinary least squares (OLS) and weighted least squares (WLS). In this paper, this approach enabled evidence of publication bias in the cited literature to be refuted. In addition, data were also collected on the academic measure and demographic information of 449 students who graduated between 2005 and 2011. For the purpose of analysis, the study utilized a stepwise logistic regression technique to examine the factors impacting on the degree outcome of real estate students.

The results of the OLS and WLS regression indicate that there is no significant evidence of any empirical effect of publication bias in the extant literature. The results of the logistic regression also revealed that grade point average, gender differences, prior knowledge of real estate discipline and potential difference in year of enrollment impact on students’ academic performance in terms of their ability to graduate at first attempt. In addition, factors such as age, marital status, high school grade and geopolitical/ethnic background of undergraduate real estate students do not influence their opportunities to graduate at first attempt from the university.

This paper focuses only on one specialized university of technology offering a bachelor’s program in real estate in Nigeria, so as to remove any extraneous factor(s) that could be present in the other institutional settings where students have completed such program. Extending similar study to tertiary institutions in Nigeria that share similar geographical characteristics and institutional settings can produce far-reaching generalization.

This paper contributes to the scanty literature on factors affecting the academic performance of students in an undergraduate real estate program in Nigeria. A scientific element of novelty in this paper is the evidence of the absence of the underlying effect of publication bias in the extant literature on students’ academic outcome in tertiary institutions. Findings from this study serve as the basis for university officers to monitor significant transitions in real estate students’ academic progress, so as to identify those who are unlikely to graduate at first attempt early at the entrant level. Generally, the outcome of this research could provide faculty and admission officers in tertiary institutions with complementary information in arriving at an informed decision in a non-discriminatory admission process.
