Purpose

This research aims to assess how well the e-governance initiative aligns with its design expectations and on-ground realities for property management to redevelop Delhi, the mega-city of India. Additionally, the study proposes strategic interventions to address any gaps identified, aiming to improve the project’s effectiveness and success.

Design/methodology/approach

The research employs a singular exploratory case study methodology to scrutinise the e-governance initiative undertaken by the Government of India to confer property rights. Specifically, the study utilises a qualitative research approach known as design-reality gap (DRG) analysis. The study draws from primary and secondary sources using a mixed-methods data collection strategy. Primary data are gathered through a purposeful and snowball sampling method involving direct engagement with respondents, whilst secondary data are sourced from the project portal.

Findings

The investigation reveals a substantial disparity between the planning and execution phases of e-governance projects. This incongruity predominantly manifests in the domains of process, staffing and skills, as well as objectives and values. The study further finds that strategic collaboration amongst stakeholders and the sustainability of decisions are the most critical factors in ensuring the success of e-governance initiatives and bridging the DRG of e-governance projects.

Research limitations/implications

This research highlights the complex challenges faced by e-governance projects in technical, human and organisational aspects. The successful implementation and sustainability of these projects require effective strategies to overcome challenges, which management should proactively identify and act on. To improve services, beneficiaries should be encouraged to provide feedback and suggestions, as they play a crucial role in service enhancement. A dynamic feedback loop would be established by creating a two-way interaction between beneficiaries and service providers, leading to iterative service improvement. It is important to note that the study’s findings are more illustrative than conclusive due to the moderate sample size, reflecting its limitations.

Originality/value

The research contributes to the scholarly discourse on e-governance and policy implementation by comprehensively examining the alignment between conceptual design and real-world execution. It also introduces a normalised scale for the DRG framework, mapping its dimensions to deduce specific outcomes. This innovative approach enhances the research’s originality and value, offering insights applicable in both academic and practical domains.

目的本研究旨在评估电子政务倡议在重新开发印度特大城市德里的过程中,在物业管理方面与其设计预期和实际情况的吻合程度。此外,本研究还提出了战略干预措施,以弥补发现的任何不足,从而提高项目的有效性和成功率。 设计/方法/途径 本研究采用了一种独特的探索性案例研究方法,对印度政府为赋予产权而采取的电子政务举措进行了仔细研究。具体而言,本研究采用了一种定性研究方法,即设计-现实差距(DRG)分析法。本研究采用混合方法的数据收集策略,从第一手和第二手资料中获取数据。原始数据是通过有目的的滚雪球式抽样方法收集的,其中包括与受访者的直接接触,而二手数据则来自项目门户网站。这种不协调主要体现在流程、人员配备和技能以及目标和价值观等方面。研究进一步发现,利益相关者之间的战略合作和决策的可持续性是确保电子政务举措取得成功和弥合电子政务项目 DRG 的最关键因素。这些项目的成功实施和可持续发展需要有效的战略来克服挑战,管理层应积极主动地发现这些挑战并采取行动。为了改进服务,应鼓励受益者提供反馈和建议,因为他们在改进服务方面发挥着至关重要的作用。通过在受益人和服务提供者之间建立双向互动,可以建立一个动态反馈回路,从而不断改进服务。值得注意的是,由于样本量适中,研究结果更多的是说明性的,而不是结论性的,这也反映了研究的局限性。研究还引入了 DRG 框架的标准化量表,通过映射 DRG 框架的各个维度来推断具体结果。这种创新方法提高了研究的原创性和价值,提供了适用于学术和实践领域的见解。

PurposeThis paper aims to explore the psychological, emotional and equity implications of compulsory acquisition, evaluate the adequacy of compensation in mitigating those consequences and assess the sustainability of cash compensation for future generations.Design/methodology/approachA case study approach was operationalised to investigate the experiences of 40 project-affected persons (PAPs) four years after a compulsory acquisition project in Ghana’s New Akrade-Mpakadan region for the construction of a railway line. These perspectives were analysed through descriptive statistics and thematic analyses using the NVivo software. Figures and a holistic framework were adopted to report the identified issues.FindingsOverall, only 25% of PAPs received formal communication prior to the acquisition, and only 10.3% have been fully compensated four years later. Despite the acquiring body initiating the marking of properties and compensation assessment in 2019, no payments were made until 2021. This induced emotional responses of distress, loss, uncertainty, stress and sadness, which was further exacerbated by feelings of hopelessness because there was no platform to voice concerns or pursue arbitration. Although PAPs were only offered compensation in the form of single monetary payments, a third would have preferred re-settlement.Research limitations/implicationsBy exploring the emotional and psychological effects of compulsory land acquisition, the study adds a new dimension to understanding its consequences. This may spark more interest, debate and discourse amongst researchers and policymakers and lead to the creation or enhancement of existing policy and legal measures to address the needs of PAPs in compulsory acquisition projects in developing countries.Originality/valueThe financial consequences of eminent domain are well documented, but this study explored the psychological, emotional and equity implications of the practice under conditions of weak regulatory frameworks. The adequacy of single lump-sum compensations was also explored to highlight preferred alternatives to ensure fairness for generations unborn.
本文旨在探讨强制征用对心理、情感和公平的影响,评估补偿是否足以减轻这些后果,并评估现金补偿对后代的可持续性。 采用案例研究法,调查了加纳新阿克拉德-姆帕卡丹地区为修建一条铁路线而实施强制征用项目四年后 40 名受项目影响者(PAPs)的经历。通过使用 NVivo 软件进行描述性统计和专题分析,对这些观点进行了分析。总的来说,只有 25% 的 PAPs 在收购前得到了正式的沟通,只有 10.3% 的 PAPs 在四年后得到了充分的补偿。尽管收购机构于 2019 年启动了财产标记和补偿评估工作,但直到 2021 年才支付任何款项。这引发了痛苦、损失、不确定性、压力和悲伤等情绪反应,由于没有表达关切或寻求仲裁的平台,绝望感进一步加剧了这种情绪。虽然 PAPs 只获得了单一的货币补偿,但有三分之一的 PAPs 更倾向于重新安置。研究的局限性/影响通过探讨强制土地征用的情感和心理影响,本研究为了解其后果增添了一个新的维度。这可能会引发研究人员和政策制定者更多的兴趣、辩论和讨论,从而制定或加强现有的政策和法律措施,以满足发展中国家强制征地项目中 PAPs 的需求。本研究还探讨了一次性补偿的适当性,以强调确保公平对待后代的首选方案。

Purpose

Meetings with colleagues are an essential activity in workplace collaboration. The iterative nature of collaborative work demands spaces that team members can access quickly and easily. Creating suitable meeting spaces will become more critical if the hybrid work model continues and the workplace environment becomes the hub for face-to-face collaborative time, learning and training. Workspace and fit-out is expensive so it is crucial that the investment in meeting spaces supports employees’ collaboration activities.

Design/methodology/approach

This paper presents a case study of a corporate organisation undertaken in New Zealand to investigate how employees from two business units use their workspace to collaborate within their own team and across other teams in their organisation. The study uses ethnographic techniques, including participant observation and in-depth face-to-face interviews.

Findings

The findings show that the frequency and nature of small group work in collaboration was underestimated in the initial planning of the new workspace. Although participants found the design and fit-out of the formal meeting rooms supportive of collaborative work, the meeting rooms were in high demand, and it was difficult to find a room at short notice. The breakout spaces were confusing because they lacked key design attributes identified by the participants as conducive to small group work. Design shortfalls together with fit-out features perceived as supportive of collaborative work are identified.

Originality/value

The research reports on employees’ perceptions and experiences across two functionally diverse business units, reflecting their different needs and concerns.

目的与同事会面是工作场所协作中必不可少的活动。协作工作的迭代性质要求团队成员能够快速、方便地使用会议空间。如果混合工作模式继续下去,工作场所环境成为面对面协作、学习和培训的中心,那么创造合适的会议空间将变得更加重要。工作空间和装修费用昂贵,因此对会议空间的投资必须能够支持员工的协作活动。本文介绍了一项在新西兰进行的企业组织案例研究,旨在调查两个业务部门的员工如何利用工作空间在自己的团队内部以及组织内其他团队之间开展协作。研究采用了人种学技术,包括参与观察和面对面的深入访谈。研究结果研究结果表明,在新工作空间的最初规划中,小组合作的频率和性质被低估了。虽然与会者认为正式会议室的设计和装修有利于协作工作,但会议室的需求量很大,很难在短时间内找到会议室。分组讨论空间令人困惑,因为它们缺乏与会者认为有利于小组工作的关键设计特 征。原创性/价值这项研究报告了两个职能不同的业务单位的员工的看法和经验,反映了他们不同的需求和关注点。

Purpose

Land value in urban areas in India is influenced by regulations, bylaws and the amenities associated with them. Planning interventions play a significant role in enhancing the quality of the neighbourhood, thereby resulting in a change in its value. Land is a distinct commodity due to its fixed location, and planning interventions are also specific to certain locations. Consequently, the factors influencing land value will vary across different areas. While recent literature has explored some determinants of land value individually, conducting a comprehensive study specific to each location would be more beneficial for making informed policy decisions. Therefore, this article aims to examine and identify the critical factors that impact the value of residential land in the National Capital Territory of Delhi, India.

Design/methodology/approach

The study employed a combination of semi-structured and structured interview methods to construct a Relative Importance Index (RII) and ascertain the critical determinants affecting residential land value. A sample of 36 experts, comprising property valuers, urban planners and real estate professionals operating within the National Capital Territory of Delhi, India, were selected using snowball sampling techniques. Subsequently, rank correlation and ANOVA methods were employed to evaluate the obtained results.

Findings

Location and stage of urban development are the most critical determinants in determining residential land values in the National Capital Territory of Delhi, India. The study identifies a total of 13 critical determinants.

Practical implications

A scenario planning approach can be developed to achieve an equitable distribution of values and land use entropy. A land value assessment model can also be developed to assist professional valuers.

Originality/value

There has been a lack of emphasis on assessing the impact of planning interventions and territorial regulation on land values in the context of Delhi. This study will contribute to policy decision-making by developing a rank list of planning-based determinants of land value.

目的印度城市地区的土地价值受到法规、附则和相关便利设施的影响。规划干预在提高社区质量方面发挥着重要作用,从而导致其价值发生变化。土地因其位置固定而成为一种独特的商品,规划干预措施也针对特定地点。因此,影响土地价值的因素在不同地区会有所不同。虽然近期的文献单独探讨了土地价值的一些决定因素,但针对每个地点进行全面研究将更有利于做出明智的决策。因此,本文旨在研究并确定影响印度德里国家首都直辖区住宅用地价值的关键因素。 这项研究采用了半结构式和结构式访谈相结合的方法来构建相对重要性指数(RII),并确定影响住宅用地价值的关键决定因素。采用滚雪球式抽样技术选取了 36 位专家,包括在印度德里国家首都直辖区工作的房地产估价师、城市规划师和房地产专业人士。研究结果在决定印度德里国家首都直辖区住宅土地价值时,地理位置和城市发展阶段是最关键的决定因素。研究共确定了 13 个关键决定因素。实际意义可以制定情景规划方法,以实现价值和土地利用熵的公平分配。还可以开发一个土地价值评估模型,为专业估价师提供帮助。原创性/价值在德里的背景下,规划干预和领土监管对土地价值的影响评估一直缺乏重视。本研究将通过制定一份基于规划的土地价值决定因素排名表,为政策决策做出贡献。

Purpose

The purpose of this study was to develop and validate a scale to assess the influence of Higher Educational Facilities for the growth of education in higher education institutions.

Design/methodology/approach

The first step in the process of scale development is to generate an item pool containing as many items as possible which captures the construct of interest. A total of 111 items were constructed for the initial try-out of the scale measuring the construct of higher educational facilities. This rating scale was based on the Likert-type was designed, where each item had to be rated on a five-point scale. The scale consisted of a few items involving the dimensions of infrastructure, quality assessment and quality assurance regard to the vision actualization.

Findings

Higher Educational Facilities Scale (HEFS) was developed by the investigator and designed in the format of a 5-point rating scale of the Likert type. There are different phases identified for the scale construction. In the first phase, items are created and the content’s validity is determined. The scale is constructed in the second phase. Pre-testing the questions, administering the survey, reducing the number of items and determining how many factors the scale captures are all steps in the scale construction process. The number of dimensions, reliability and validity are all verified in the third phase, scale evaluation. In developing the scale, the content and face validity was ascertained. The reliability of the scale and its three subscales were established. This scale has potential value for policymakers to assess the perception held by the religious faculty members working in higher education institutions.

Originality/value

The research is part of the doctoral thesis by Dr Deepa Thomas under the supervision of Dr Fr. Joseph C. C. and the co-supervision of Dr Kennedy Andrew Thomas. The purpose of the scale is to assess the higher educational facilities of in institutions of higher Education. Quality, excellence and service are the vision and purpose of higher education institutions to provide ample opportunities and good facilities for their beneficiaries, thus creating tremendous changes in the Indian education scenario.

本研究的目的是开发并验证一个量表,以评估高等教育设施对高等教育机构教育发展的影响。设计/方法/途径量表开发过程的第一步是生成一个项目库,其中包含尽可能多的项目,以捕捉感兴趣的建构。在测量高等教育设施构念的量表的初步尝试中,共构建了 111 个项目。这个评分量表是基于李克特量表设计的,每个项目都必须用五点量表来评分。研究结果 高等教育设施量表(HEFS)由研究者编制,采用李克特式 5 点评分量表。量表的编制分为不同的阶段。在第一阶段,创建项目并确定内容的有效性。在第二阶段构建量表。对问题进行预先测试、实施调查、减少项目数量以及确定量表所包含的因素数量都是量表构建过程中的步骤。量表的维数、信度和效度都将在第三阶段,即量表评估中得到验证。在编制量表的过程中,要确定内容效度和表面效度。量表及其三个分量表的信度已经确定。本量表对政策制定者评估高等教育机构宗教教职人员的看法具有潜在价值。该量表旨在评估高等教育机构的高等教育设施。质量、卓越和服务是高等教育机构的愿景和宗旨,为受益者提供充足的机会和良好的设施,从而为印度的教育状况带来巨大的变化。

Purpose

Foreign direct investment in the real estate (FDIRE) sector is required to bridge the gap between investment needed and domestic funds. Further, foreign direct investment is gaining importance because other sources of raising finance such as External Commercial Borrowing and foreign currency convertible bonds have been banned in the Indian real estate sector. Therefore, the objective of the study is to explore the determinants attracting foreign direct investment in real estate and to assess the impact of those variables on foreign direct investments in real estate.

Design/methodology/approach

Johansen cointegration test, vector error correction model along with variance decomposition and impulse response function are employed to understand the nexus of the relationship between various macroeconomic variables and foreign direct investment in real estate.

Findings

The results indicate that infrastructure, GDP and tourism act as drivers of foreign direct investment in real estate. However, interest rates act as a barrier.

Originality/value

This article aimed at exploring factors attracting FDIRE along with estimating the impact of identified variables on FDI in real estate. Unlike other studies, this study considers FDI in real estate instead of foreign real estate investments.

目的 房地产行业需要外国直接投资(FDIRE)来弥补投资需求与国内资金之间的缺口。此外,由于印度房地产行业已禁止外部商业借款和外币可转换债券等其他融资渠道,因此外国直接投资的重要性日益凸显。因此,本研究的目的是探讨吸引外国对房地产直接投资的决定因素,并评估这些变量对外国对房地产直接投资的影响。研究结果结果表明,基础设施、国内生产总值和旅游业是外国对房地产直接投资的驱动因素。原创性/价值本文旨在探讨吸引外国直接投资的因素,并估计已确定的变量对房地产外国直接投资的影响。与其他研究不同的是,本研究考虑的是房地产领域的外国直接投资,而不是外国房地产投资。

Purpose

With the increased demand for the application of technology in property activities, there is a growing need for property professionals adept in using digital technology. Hence, it is important to assess the competence of academia in equipping property professionals with digital technology skills. This study, therefore, assesses property academics in Australian universities to identify their level of knowledge and use of digital technology applicable to the property industry.

Design/methodology/approach

Online questionnaire surveys were administered to 22 out of 110 property academics contacted through the Australia Property Institute (API) database to achieve this aim. The collected data were analysed using mean score ranking and ANOVA.

Findings

The study found that apart from databases and analytics platforms such as Corelogic RP data, price finder and industry-based software such as the Microsoft Office suite and ARGUS software, the academics were not knowledgeable in most identified and sampled proptech tools. Similarly, most proptech tools were not used or taught to the students. It was also found that early career academics (below five years in academia) were the most knowledgeable group about the proptech tools.

Research limitations/implications

Relying on the API database to contact property academics potentially excludes the position of property academics who may not be affiliated or have contacts with API, hence, the findings of this study should be generalised with caution.

Practical implications

The study bears huge implications for the property education sector and industry in Australia; a low knowledge and use of nascent tools such as artificial intelligence, machine learning, blockchain, drones, fintech, which have received intense interest, reveals some level of skill gap of students who pass through that system and may need to be upskilled by employers to meet the current day demand.

Originality/value

In response to the clamour for technology-inclined property professionals, this paper presents itself as the first to assess the knowledge levels and application of digital technology by property academics.

目的随着在物业活动中应用科技的需求日益增加,对善于使用数码科技的物业专业人员的需求也与日俱增。因此,评估学术界在培养物业专业人员掌握数字技术技能方面的能力非常重要。因此,本研究对澳大利亚大学的房地产学者进行了评估,以确定他们对适用于房地产行业的数字技术的了解和使用水平。为实现这一目标,我们通过澳大利亚房地产协会(API)数据库联系了 110 名房地产学者,并对其中的 22 名进行了在线问卷调查。研究结果研究发现,除了 Corelogic RP 数据、价格搜索器等数据库和分析平台以及微软办公套件和 ARGUS 软件等基于行业的软件外,学者们对大多数已识别和抽样的物业技术工具并不了解。同样,大多数 Proptech 工具也没有被使用或教授给学生。研究的局限性/启示依赖于 API 数据库与房地产学者取得联系,可能会排除那些可能与 API 无关或没有联系的房地产学者,因此,应谨慎归纳本研究的结果。实践意义本研究对澳大利亚的房地产教育部门和行业具有重大意义;对人工智能、机器学习、区块链、无人机、金融科技等新生工具的了解和使用程度较低,这引起了人们的浓厚兴趣,揭示了通过该系统学习的学生在某种程度上存在技能差距,雇主可能需要提高他们的技能,以满足当前的需求。原创性/价值为了响应对技术型房地产专业人士的需求,本文首次对房地产学者的数字技术知识水平和应用进行了评估。

PurposeStudies showed that stakeholders want the construction sector’s organisations to be more accountable and transparent regarding social and environmental issues through corporate social responsibility (CSR). There is a paucity of literature regarding CSR implementation in the construction sector, especially in developing countries like South Africa. Hence, the study evaluated CSR’s merits and hindrances and suggested solutions to enhance its implementation in the South African construction sector of Mpumalanga Province.Design/methodology/approachThe researchers employed a questionnaire survey method to collect data from 68 useable respondents in the South African construction sector of Mpumalanga Province. The main section of the questionnaire was divided into three parts, each addressing an objective mean item score ranking technique.FindingsFindings show management lacks willingness, absence of recognition for implementing CSR at tender adjudication, professionals regard CSR as a “soft issue,” inadequate ability to carry out CSR initiatives and lax CSR knowledge emerged as the key issues hindering construction stakeholders, especially construction companies, from participating in CSR in South Africa. The research suggests initiatives to enhance CSR in the construction industry.Originality/valueThe study shows that the findings can be used to improve the implementation of CSR engagement and possibly enhance a policy to stimulate friendly CSR in the South African construction sector.
目的研究表明,利益相关者希望建筑行业的组织通过企业社会责任(CSR)在社会和环境问题上更加负责和透明。有关在建筑行业,尤其是南非等发展中国家实施企业社会责任的文献很少。因此,本研究评估了企业社会责任的优点和阻碍因素,并提出了在南非姆普马兰加省建筑行业加强实施企业社会责任的解决方案。 研究人员采用问卷调查法,从南非姆普马兰加省建筑行业的 68 名可用受访者那里收集数据。研究结果表明,管理层缺乏意愿、在投标评审中缺乏对企业社会责任实施的认可、专业人士将企业社会责任视为 "软问题"、实施企业社会责任倡议的能力不足以及企业社会责任知识匮乏是阻碍南非建筑业利益相关者(尤其是建筑公司)参与企业社会责任的关键问题。该研究提出了在建筑行业加强企业社会责任的倡议。原创性/价值该研究表明,研究结果可用于改进企业社会责任参与的实施,并有可能加强南非建筑行业促进友好型企业社会责任的政策。

PurposeThe Heating, Ventilation and Air Conditioning (HVAC) system is a significant energy consumer in built environments, and the building energy consumption could be minimised by optimising HVAC controls. Hence, this paper aims to investigate the applicability of Variable Refrigerant Flow (VRF) air conditioning systems for optimising the indoor comfort of buildings in Sri Lanka.Design/methodology/approachTo address the research aim, the quantitative approach following the survey research strategy was deployed. Data collected through questionnaires were analysed using descriptive statistical tools, including Mean Rating (MR), Relative Important Index (RII) and Standard Deviation (SD).FindingsThe findings revealed that VRF systems are popularly used in Sri Lankan apartment buildings. Furthermore, energy efficiency and comfort were recognised as the most significant top-ranked benefits, while ventilation issues and initial cost were recognised as significant challenges. Moreover, the allocation of trained technicians and provision of proper ventilation through a Dedicated Outdoor Air System (DOAS) were highlighted as applicable mitigation strategies for the identified challenges in VRFs.Practical implicationsThe study recommends VRF systems as a suitable technology to ensure energy efficiency, reduce GHG emissions and achieve climate performance within the built environment. The opportunities for adopting VRF systems for developing countries could be explored based on the research findings. The identified challenges would assist the design engineers and facilities professionals to devise suitable strategies to mitigate issues of VRF systems in developing countries.Originality/valueThis research provides empirical proof of the energy efficiency and comfort aspects of VRFs. The study has explored and recommended VRF technology as a beneficial application to overcome the persistent energy crisis in developing countries.
目的暖通空调(HVAC)系统是建筑环境中的重要能源消耗,通过优化暖通空调控制可以最大限度地降低建筑能耗。因此,本文旨在研究变制冷剂流量(VRF)空调系统在优化斯里兰卡建筑物室内舒适度方面的适用性。通过调查问卷收集的数据使用描述性统计工具进行分析,包括平均值(MR)、相对重要指数(RII)和标准偏差(SD)。此外,能效和舒适度被认为是最重要的优势,而通风问题和初始成本被认为是重大挑战。此外,针对 VRF 系统所面临的挑战,还强调了分配训练有素的技术人员和通过专用室外空气系统 (DOAS) 提供适当通风的适用缓解策略。可以根据研究结果探索发展中国家采用 VRF 系统的机会。已确定的挑战将有助于设计工程师和设施专业人员制定适当的策略,以缓解发展中国家的 VRF 系统问题。研究探讨并推荐了 VRF 技术,认为它是克服发展中国家持续能源危机的有益应用。
