Abstract

Purpose

The purpose of this study is to examine the standards, strategies, support and challenges of digital preservation in institutional repositories in academic libraries in Ghana.

Design/methodology/approach

The research was qualitative. Data used for analysis were drawn from interviews with respondents selected purposively from eight Ghanaian academic libraries.

Findings

A key finding of the study was that although the academic libraries had operational directions for digital preservation activities in the institutional repositories, available standards and practices for ensuring long-term preservation seem to be unsuitable.

Research limitations/implications

Recommendations based on findings included development of comprehensive digital preservation policies to provide mandate and direction to preservation of the libraries digital collections, development of disaster plans, adequate funding, staff development and support from management.

Originality/value

The study has demonstrated the need for academic libraries in Ghana to have and develop good digital preservation standards for sustaining the institutional repositories to help in realizing its benefits.

This study investigates information flow of market constituents and global indices at multi-frequencies.

Abstract

Purpose

This study investigates information flow of market constituents and global indices at multi-frequencies.

Design/methodology/approach

The study’s findings were obtained using the Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (I-CEEMDAN)-based cluster analysis executed for Rényi effective transfer entropy (RETE).

Findings

The authors find that significant negative information flows among sustainability equities (SEs) and conventional equities (CEs) at most multi-frequencies, which exacerbates diversification benefits. The information flows are mostly bi-directional, highlighting the importance of stock markets' constituents and their global indices in portfolio construction.

Research limitations/implications

The authors advocate that both SE and CE markets are mostly heterogeneous, revealing some levels of markets inefficiencies.

Originality/value

The empirical literature on CEs is replete with several dynamics, revealing their returns behaviour for diversification purposes, leaving very little to know about the returns behaviour of SE. Wherein, an avalanche of several initiatives on Corporate Social Responsibility (CSR) enjoin firms to operate socially responsible, but investors need to have a clear reason to remain sustainable into the foreseeable future period. Accordingly, the humble desire of investors is the formation of a well-diversified portfolio and would highly demand stocks to the extent that they form a reliable portfolio, especially, amid SEs and/or CEs.

研究目的

本研究擬審查多頻率的及為市場成份的信息流和全球指數。

研究設計/方法/理念

研究人員使用基於改良完全集合經驗模態分解自適應噪聲(Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise)的聚類分析法,取得Rényi有效轉移熵,藉此得到研究結果。

研究結果

我們發現、於大部份多頻率,在持續性股票和傳統股票間有顯著的負信息流動,這會增加多樣化的益處。這些信息流大部份是雙向的,這強調了股票市場成份及其全球指數在構建投資組合上的重要性。

研究的局限/啟示

我們認為持續性股票市場和傳統股票市場大多為異質市場,這顯示了市場的低效率,而且這低效率的程度頗大。

研究的原創性/價值

關於傳統股票的實證性文獻裡是充滿了變革動力的,這顯示了它們以多樣化為目的的回報行為。這使我們對關於持續性股票的回報行為、認識變得實在太少了。於此,大量的企業社會責任的新措施不斷提醒各公司、要本著企業社會責任的理念去營運;但投資者需清晰明白他們為何需在可見的將來保持可持續性。因此,他們卑微的願望是一個較好的多樣化投資組合得以形成,故此他們高度要求股票要有組成可靠投資組合的性質和能力,特別是在持續性股票和/或傳統股票當中。

Abstract

Purpose

Knowledge of the effect of various cash-flow factors on expected project profit is important to effectively manage productivity on construction projects. This study was conducted to develop and test the sensitivity of a Machine Learning Support Vector Regression Algorithm (SVRA) to predict construction project profit in Ghana.

Design/methodology/approach

The study relied on data from 150 institutional projects executed within the past five years (2014–2018) in developing the model. Eighty percent (80%) of the data from the 150 projects was used at hyperparameter selection and final training phases of the model development and the remaining 20% for model testing. Using MATLAB for Support Vector Regression, the parameters available for tuning were the epsilon values, the kernel scale, the box constraint and standardisations. The sensitivity index was computed to determine the degree to which the independent variables impact the dependent variable.

Findings

The developed model's predictions perfectly fitted the data and explained all the variability of the response data around its mean. Average predictive accuracy of 73.66% was achieved with all the variables on the different projects in validation. The developed SVR model was sensitive to labour and loan.

Originality/value

The developed SVRA combines variation, defective works and labour with other financial constraints, which have been the variables used in previous studies. It will aid contractors in predicting profit on completion at commencement and also provide information on the effect of changes to cash-flow factors on profit.

Abstract

Purpose

The purpose of this study is to determine the extent to which total quality management (TQM) initiatives can improve the quality of services delivery at the medical records unit of the Korle-Bu Teaching Hospital (KBTH) to help meet the expectations and aspirations of patients and customers of the hospital.

Design/methodology/approach

This research adopted the survey strategy as its research design. The total study population consisted of 114 medical records staff of the KBTH. Questionnaires and personal observations were employed as the data collection instruments. The study recorded a response rate of 98 per cent. Data gathered from respondents were analysed in qualitative terms.

Findings

The overall finding of this study was that, although the medical records department of the KBTH had a fair degree of understanding on the benefits of TQM to records management service delivery, the exiting values for TQM did not meet the framework of good TQM practice, principles and standards.

Research limitations/implications

Even though the subjects for the study were from the biggest hospital in Ghana, the findings of this study may not be generalised to the whole country.

Practical implications

The study has demonstrated the need for the medical records department of the KBTH to have and develop good TQM standards to improve the quality of services to patients and varied customers of the hospital.

Originality/value

The literature reviewed indicated that this study is a maiden attempt to examine how TQM initiatives including sensitivity, customer satisfaction, commitment of top management, team work, effective leadership and participatory management, people development and effective and open communication can improve the quality of medical records service delivery at the KBTH in Ghana.

Abstract

Purpose

The purpose of this paper is to explore the extent to which digital preservation facilitate the implementation of electronic government, open data and the right to information.

Design/methodology/approach

A case study research which chronicles the link between transparency and data availability. It makes use of a theoretical framework based on the open archival information system to analyse, explain, clarify and justify the application of open data, electronic government and the right to information.

Findings

The paper argued that e-government, open data and the RTI will remain elusive if a digital preservation infrastructure is not pursued. Within the context of e-government, the paper adumbrated that government agencies can incorporate e-government legislations into their digital preservation activities, precisely because the relationship between digital preservation and e-government have always been symbiotic. It alluded to the fact that an obligation will be placed on all public authorities and private agencies covered by the RTL law to create, keep and organise an effective and efficient system of record keeping, so as to give meaning to the right to information when citizens apply for information.

Practical implications

Future research should examine closely the implication of open data government within the context of digital preservation. Whilst digital preservation looks forward to the longevity of digital records and its accessibility, open data focusses on the utility of these records through online services, reuse and distribution for the purposes of transparency and citizens’ participation.

Originality/value

The application of digital preservation to open data in this paper appears to be more relevant at a time when most governments of the world are striving to obtain data to fight poverty, achieve universal primary education, fight HIV and foster maternal health. Its originality can further be established from the symbiotic relationship between digital preservation and electronic government, open data and the right to information.

Abstract

Purpose

This study aims to investigate the cyber security awareness and policies within corporate organisations in Ghana.

Design/methodology/approach

Using both quantitative and qualitative approaches underpinned by questionnaire and document analysis, data were collected from 100 participants centred on cyber security awareness and information policies.

Findings

The study underscored that, although corporate organisations had a good knowledge of IT, their awareness of cyber security remains limited. It observed that most organisations in Ghana are not integrating legal aspects into their information security policies. It proposed the need to increase the security awareness of corporate organisation, particularly because of the vulnerabilities they are exposed to.

Research limitations/implications

The implication of the paper with respect to theory, practice and future research lies in the recommendations the authors have proffered, such as the implementation of security awareness training programme, need assessment and the outsourcing of qualified service providers.

Practical implications

The study is useful for policy makers in the management of Ghana’s IT infrastructure.

Originality/value

This study is being undertaken at a period when Ghana has made progressive development and giant steps in the IT industry compared to its counterparts in sub-Saharan Africa. The developed nature of Ghana’s IT infrastructure requires the development of policies for cyber security to prevent data loses and protect the national infrastructure from threats. Undertaking a study on cyber security in an environment where cyber issues are hardly discussed is worthwhile.

Abstract

Purpose

The authors examine the effect of supply chain resilience (SCR) on supply chain performance (SCP) while considering the moderating effect of supply chain network complexity (SCNC) on the nexus between SCR and SCP of manufacturing firms.

Design/methodoqlogy/approach

The quantitative research approach and explanatory research design were utilised for this study. A sample of 345 manufacturing firms in the Accra metropolis was drawn. The partial least square structural equation modelling was employed.

Findings

Findings from the study revealed that SCR has a significant positive effect on SCP. However, SCNC had a significant negative moderating effect on the relationship between SCR and SCP.

Practical implications

The authors advocate that manufacturing firms are prone to stronger impact from complex networks that mitigate the already existing positive relationship between SCR and SCP and is dependent on the context in which the study is executed, and the extent to which resilience strategies are robust. Thus, the SCNC has an adverse impact on how well partners interact and how well the supply chain functions.

Originality/value

This is the first study that quantitatively investigates the SCR impact on SCP in the presence of SCNC of manufacturing firms in the context of a developing economy. The study redefines SCNC from earlier studies.

Abstract

Purpose

Despite the economic growth in Ghana, the manufacturing industry faces numerous challenges in their supply chains. The study aims to investigate the mediated-moderated role of supply chain technological innovation (SCTI) in the relationship between supply chain resilience (SCR) and supply chain performance (SCP) of manufacturing firms. By exploring this relationship, the study seeks to provide insights that can help manufacturing firms overcome the challenges they face and improve their overall supply chain performance.

Design/methodology/approach

The quantitative research approach and explanatory research design were utilised. A sample of 345 manufacturing firms was drawn from a population of 2495 manufacturing firms in the Accra metropolis. Analysis of this study was performed using the Partial Least Squares Structural Equation Modelling (PLS-SEM).

Findings

It was revealed that SCTI positively mediates the nexus between SCR and SCP. However, we document that SCTI negatively moderates the nexus. It is instructive to advocate that a mere presence of a more enhanced SCTI is not enough to improve upon SCP of manufacturing firms, but should be a channel through which SCR can improve SCP.

Practical implications

This study highlights the need for managers of firms to prioritise investment in technological innovation as a means of enhancing SCR and ultimately improving supply chain performance. By understanding the SCTI mediated-moderated relationship between SCR and SCP, supply chain managers, logistics managers, operation managers, as well as procurement managers can develop more effective strategies to optimise their operations. This study provides valuable insights for managers and policymakers in developing and implementing supply chain resilience strategies that take into account the important role of SCTI.

Originality/value

The originality of the study lies in exploring the mediated-moderated effect of technological innovation on the nexus between resilience and performance of supply chains in developing economies, where firms often face unique challenges such as infrastructure limitations, political instability and economic uncertainty. By investigating the interplay of SCTI between SCR and SCP, researchers can develop new insights and strategies to help navigate these challenges and achieve success.

Abstract

Purpose

What people understand by climate change can differ depending on whether and how the change affects their livelihoods. It is largely documented that farmers who depend on rainfall to cultivate crops understand climate change as a change in climatic elements, especially rainfall which negatively affects crop production. However, studies on how people whose livelihoods do not directly depend on climate change understand it, whether and how the changes affect their livelihoods and whether and how they are coping to the change are limited in the literature. This paper aims to therefore determine perspective of traders of climate change and how they cope.

Design/methodology/approach

The data collection took place in Accra, which is the capital city of Ghana. Thousand traders who sold unprocessed and processed food as well as manufactured goods took part in the study. Questionnaires which were largely open-ended were administered. SPSS version 16 was used to analyse the data. In addition, some of the interview responses were included verbatim to support study participants view on some issues.

Findings

The majority of the respondents engaged in trading of manufactured goods. The respondents understood climate change as prolonged dry season and changes in rainfall pattern. About 97 per cent of the respondents said climate change had negatively impacted their trading activities, and almost all respondents (91 per cent) who were affected by climate change livelihoods were also affected such that they were unable to meet their basic needs. About 23 per cent have adopted coping strategies by depending on friends, relatives and engaging in menial jobs, and 63 per cent adopted no coping strategy.

Originality/value

It seems that rural farmers may have more options than urban traders during climate change. This can mean that research and policy efforts towards adaption to climate change should not focus only on farmers but traders as well.

Abstract

Purpose

This study was conducted to identify, summarise, analyse and categorise mobile device applications (Apps), relevant to the construction industry and to explore their uses and exposure levels.

Design/methodology/approach

The research method involved reviewing literature and searching for Apps. The construction Apps were found by developing key phrases. These key phrases were used to develop search strategies, which were then used to find the construction Apps. The Apps found were categorised based on the similarity of their uses.

Findings

The 136 Apps identified were summarised, analysed, and categorised into 11 groups of distinct construction operations and tasks. The “Design and Drawing Apps”, “Measurement and Estimation Apps”, “Management Apps”, “All Round Apps” and “Construction Site Apps” recorded 29, 28, 26, 21 and 11 numbers of Apps, respectively. The Autodesk Sketchbook, GPS Field Area Measure, MagicPlan, Measure and TSheets were the top five in terms of the number of downloads. These Apps in terms of their exposure levels in the construction industry record 4.76%, 2.38%, 0.52%, 0.48% and 0.42%, respectively.

Originality/value

This paper provides a catalogue of the continuum of construction Apps for a wide variety of construction operations/activities which are available for construction professionals and provide guidance on their uses to assist in selecting appropriate Apps for specified operation/tasks/activities in the construction industry. Construction professionals may benefit from increased productivity, efficiency and ease of working.
