    • The nature of the self, self‑regulation and moral action: implications from the Confucian relational self and Buddhist non‑self

      Chu, Irene; Vu, M.C. (Springer, 2021-05)
      The concept of the self and its relation to moral action is complex and subject to varying interpretations, not only between different academic disciplines but also across time and space. This paper presents empirical evidence from a cross-cultural study on the Buddhist and Confucian notions of self in SMEs in Vietnam and Taiwan. The study employs Hwang’s Mandala Model of the Self, and its extension into Shiah’s non-self-model, to interpret how these two Eastern philosophical representations of the self, the Confucian relational self and Buddhist non-self, can lead to moral action. By demonstrating the strengths of the model, emphasizing how social and cultural influences constrain the individual self and promote the social person leading to moral action, the paper extends understanding of the self with empirical evidence of the mechanisms involved in organizational contexts
    • Solution processed PVB/mica flake coatings for the encapsulation of organic solar cells

      Channa, I.A.; Chandio, A.D.; Rizwan, M.; Shah, A.A.; Bhatti, J.; Shah, A.K.; Hussain, F.; Shar, Muhammad A.; AlHazaa, A. (2021-05-12)
      Organic photovoltaics (OPVs) die due to their interactions with environmental gases, i.e., moisture and oxygen, the latter being the most dangerous, especially under illumination, due to the fact that most of the active layers used in OPVs are extremely sensitive to oxygen. In this work we demonstrate solution-based effective barrier coatings based on composite of poly(vinyl butyral) (PVB)and mica flakes for the protection of poly (3-hexylthiophene) (P3HT)-based organic solar cells (OSCs)against photobleaching under illumination conditions. In the first step we developed a protective layer with cost effective and environmentally friendly methods and optimized its properties in terms of transparency, barrier improvement factor, and bendability. The developed protective layer maintained a high transparency in the visible region and improved oxygen and moisture barrier quality by the factor of ~7. The resultant protective layers showed ultra-flexibility, as no significant degradation in protective characteristics were observed after 10 K bending cycles. In the second step, a PVB/mica composite layer was applied on top of the P3HT film and subjected to photo-degradation. The P3HT films coated with PVB/mica composite showed improved stability under constant light irradiation and exhibited a loss of <20% of the initial optical density over the period of 150 h. Finally, optimized barrier layers were used as encapsulation for organic solar cell (OSC) devices. The lifetime results confirmed that the stability of the OSCs was extended from few hours to over 240 h in a sun test (65◦C, ambient RH%) which corresponds to an enhanced lifetime by a factor of 9 compared to devices encapsulated with pristine PVB.
    • The scope of carer effects and their inclusion in decision-making: A UK-based Delphi study

      Al-Janabi, H.; Efstathiou, N.; McLoughlin, C.; Calvert, M.; Oyebode, Jan R. (BMC, 2021)
      Background and objective: Health and social care may affect family carers’ health and wellbeing in addition to patients’ lives. It is recommended that such impacts (carer effects) are considered in decision-making. However, the scope of carer effects and range of decisions where carer effects should be considered is uncertain. This study aimed to identify (i) how different categories of healthcare and social care were perceived to impact on family carers and (ii) whether there was consensus about when carer effects should be formally considered in decision-making contexts. Methods: A Delphi study was conducted with 65 UK-based participants with expertise in dementia, mental health, and stroke. Participants considered two broad forms of ‘interventions’ (patient treatment and replacement care) and two broad forms of ‘organisational change’ (staffing and changes in timing/location of care). Participants assessed the likely impacts of health and social care on family carers and whether impacts should be considered in decision-making. The survey was conducted remotely at two time points. Results: Participants predicted widespread impacts from interventions and organisational changes on different domains of family carers’ lives, with ‘emotional health’ the most likely outcome to be affected. Patient treatment and replacement care services (‘interventions’) were associated with positive impacts across all domains. Conversely, timing/location changes and staffing changes (‘organisational changes’) were perceived to have mixed and negative impacts. There was widespread support (80-81%) for considering carer effects in research studies, funding decisions, and patient decision-making. Conclusion: This study highlights a perception that carer effects are widespread and important to consider in economic evaluation and decision-making. It highlights the particular need to measure and value effects on carers’ emotional health and the need to use a societal perspective to avoid cost shifting to family carers when introducing interventions and making organisational changes.
    • Resilient and Sustainable Supply Chain Networks: A Case Study of the Perishable Food Industry in the US

      Mishra, Jyoti L.; Hussain, Zahid I.; Barber, Kevin D.; Drabble, Brian; Chiwenga, Kudzai D. (University of BradfordFaculty of Management, Law and Social Sciences, 2019)
      Contemporary supply chain management (SCM) issues are multiplex and continually evolving catalysed by complexities and dynamism. The perishable food industry exemplifies this phenomenon, driven by globalisation, technological advancements and a highly competitive business environment. Inescapably, food supply chains are increasingly operating as supply chain networks (SCN). SCNs are typified by a higher level of interdependence and connectivity amongst firms, consequently evolving from dyad and triad relationships, which have dominated SCM research. These changes generate divergent risks and vulnerabilities that perturb perishable food supply chains in unconventional ways. Thus, the purpose of this empirical study is to investigate how firms within a perishable food supply chain network can build resilience and sustainability. The research focuses on advancing the management of fast-moving consumer goods (FMCG). Methodologically, an empirical qualitative study is undertaken within a food manufacturer (focal firm) and 18 independent firms operating across all tiers of its SCN. Applying a pragmatic philosophical positioning, the study draws concepts from key supply chain theories to investigate the phenomena. The investigation uses Nicolini’s Zooming in and Zooming out as an analytical lens. The zooming in and out is established by shifting analytical lenses and re-positioning actors’ praxis, to ensure certain facets of their actions are fore-grounded while others are put in a background position and contrariwise moving the background to the foreground. The purpose of this technique is to draw meaning from everyday practices and trace the actions of actors across the entire SCN. The results uncover four distinct but intertwined main categories; whose subtle and often ignored interplay is crucial in attaining SCN resilience and sustainability. These main categories are Collaboration, Power Dynamics, SCN Culture and Information Systems. Current supply chain literature argues that collaboration is an essential enabler of resilience and sustainability. Building on this, the findings make a significant contribution by teasing out the intangible and predominately unacknowledged antecedents and salient sustaining factors of effective SCN collaboration. Furthermore, the study develops a resilience and sustainability (RS) matrix, which renders different impacts and outcomes of varying levels of SCN collaboration between firms operating in a perishable food SCN. Therefore, this thesis contributes knowledge towards constructing resilient and sustainable perishable food SCNs by proffering pragmatic propositions. These aim to address challenges facing industry stakeholders and ignite pertinent future research avenues for scholars.
    • Design of a self-learning multi-agent framework for the adaptation of modular production systems

      Scrimieri, Daniele; Afazov, S.M.; Ratchev, S.M. (2021)
      This paper presents the design of a multi-agent framework that aids engineers in the adaptation of modular production systems. The framework includes general implementations of agents and other software components for self-learning and adaptation, sensor data analysis, system modelling and simulation, as well as human-computer interaction. During an adaptation process, operators make changes to the production system, in order to increase capacity or manufacture a product variant. These changes are automatically captured and evaluated by the framework, building an experience base of adjustments that is then used to infer adaptation knowledge. The architecture of the framework consists of agents divided in two layers: the agents in the lower layer are associated with individual production modules, whereas the agents in the higher layer are associated with the entire production line. Modelling, learning, and adaptations can be performed at both levels, using a semantic model to specify the structure and capabilities of the production system. An evaluation of a prototype implementation has been conducted on an industrial assembly system. The results indicate that the use of the framework in a typical adaptation process provides a significant reduction in time and resources required.
    • A systematic review to identify research priority setting in Black and minority ethnic health and evaluate their processes

      Iqbal, Halima; West, J.; Haith-Cooper, Melanie; McEachan, R.R.C. (PLOS ONE, 2021-05)
      Background: Black, Asian and minority ethnic communities suffer from disproportionately poorer health than the general population. This issue has been recently exemplified by the large numbers of infection rates and deaths caused by covid-19 in BAME populations. Future research has the potential to improve health outcomes for these groups. High quality research priority setting is crucial to effectively consider the needs of the most vulnerable groups of the population. Objective: The purpose of this systematic review is to identify existing research priority studies conducted for BAME health and to determine the extent to which they followed good practice principles for research priority setting. Method: Included studies were identified by searching Medline, Cinnahl, PsychINFO, Psychology and Behavioral Sciences Collection, as well as searches in grey literature. Search terms included “research priority setting”, “research prioritisation”, “research agenda”, “Black and minority ethnic”, “ethnic group”. Studies were included if they identified or elicited research priorities for BAME health and if they outlined a process of conducting a research prioritisation exercise. A checklist of Nine Common Themes of Good Practice in research priority setting was used as a methodological framework to evaluate the research priority processes of each study. Results: Out of 1514 citations initially obtained, 17 studies were included in the final synthesis. Topic areas for their research prioritisation exercise included suicide prevention, knee surgery, mental health, preterm birth, and child obesity. Public and patient involvement was included in eleven studies. Methods of research prioritisation included workshops, Delphi techniques, surveys, focus groups and interviews. The quality of empirical evidence was diverse. None of the exercises followed all good practice principles as outlined in the checklist. Areas that were lacking in particular were: the lack of a comprehensive approach to guide the process; limited use of criteria to guide discussion around priorities; unequal or no representation from ethnic minorities, and poor evaluation of their own processes. Conclusions: Research priority setting practices were found to mostly not follow good practice guidelines which aim to ensure rigour in priority setting activities and support the inclusion of BAME communities in establishing the research agenda. Research is unlikely to deliver useful findings that can support relevant research and positive change for BAME communities unless they fulfil areas of good practice such as inclusivity of key stakeholders’ input, planning for implementation of identified priorities, criteria for deciding on priorities, and evaluation of their processes in research priority setting.
    • An exploration of migrant women’s perceptions of public health messages to reduce stillbirth in the UK: a qualitative study

      Stacey, T.; Haith-Cooper, Melanie; Almas, Nisa; Kenyon, C. (2021-05)
      Background: Stillbirth is a global public health priority. Within the United Kingdom, perinatal mortality disproportionately impacts Black, Asian and minority ethnic women, and in particular migrant women. Although the explanation for this remains unclear, it is thought to be multidimensional. Improving perinatal mortality is reliant upon raising awareness of stillbirth and its associated risk factors, as well as improving maternity services. The aim of this study was to explore migrant women’s awareness of health messages to reduce stillbirth risk, and how key public health messages can be made more accessible. Method: Two semi-structured focus groups and 13 one to one interviews were completed with a purposive sample of 30 migrant women from 18 countries and across 4 NHS Trusts. Results: Participants provided an account of their general awareness of stillbirth and recollection of the advice they had been given to reduce the risk of stillbirth both before and during pregnancy. They also suggested approaches to how key messages might be more effectively communicated to migrant women. Conclusions: Our study highlights the complexity of discussing stillbirth during pregnancy. The women in this study were found to receive a wide range of advice from family and friends as well as health professionals about how to keep their baby safe in pregnancy, they recommended the development of a range of resources to provide clear and consistent messages. Health professionals, in particular midwives who have developed a trusting relationship with the women will be key to ensuring that public health messages relating to stillbirth reduction are accessible to culturally and linguistically diverse communities.
    • Towards a multidimensional approach to measure quality and safety of care in maternity units in Oman

      Mohammed, Mohammed A.; Faisal, Muhammad; Al Nadabi, Waleed K.A. (University of BradfordFaculty of Health Studies, 2019)
      Improving the quality and safety of maternity services is an international top agenda item. This thesis describes the progress towards the development of a multidimensional approach to measure the quality and safety of care in ten maternity units in Oman based on three of the five dimensional Patient Safety Measurement and Monitoring Framework (PSMMF) which include measuring "past harm" and "anticipation and preparedness”. The three monitoring approaches used in this research are: (1) measuring the patient safety culture (2) measuring patient satisfaction (3) and monitoring caesarean section rates. The specific objectives of the research are to (1) measure patient safety culture level, (2) examine the association between nurse’s nationality and patient safety culture, (3) validate an Arabic language survey to measure maternal satisfaction about the childbearing experience, (4) measure patient satisfaction about the childbearing experience, and (5) to examine caesarean section rates across maternity units using statistical process control charts. This thesis started with four systematic reviews that focused on (1) the use of patient safety culture for monitoring maternity units (2) the available interventions to improve patient safety culture (3) Arabic surveys available for measuring maternal satisfaction and (4) the use of statistical process control charts for monitoring performance indicators. The overall conclusion from these reviews that these approaches are being increasingly used in maternity, found feasible and useful, and there are areas that need attention for future work. Five field studies were conducted to address the research aim and objectives. Patient safety culture was measured by a cross-sectional survey of all staff in the ten maternity units. It was found that safety culture in Oman is below the target level and that there is wide variation in the safety scores across hospitals and across different categories of staff. Non-Omani nurses have a more positive perception of patient safety culture than Omani nurses in all domains except in respect of stress recognition and this difference need further investigation and needs to be considered by designers of interventions to enhance patient safety culture. Using two existing validated English surveys, an Arabic survey was developed, validated, and used to measure maternal satisfaction with childbirth services. It was found that the new survey has good psychometric properties and that in all the ten hospitals, mothers were satisfied with the care provided during child delivery but satisfaction score varied across hospitals and groups of participants. Caesarean section rate in the last 17 years was examined using statistical process control charts to understand the variation across the ten hospitals. It was found that caesarean section rate is above the rate recommended by the World Health Organisation. Special cause variations were detected that warrant further investigation. In conclusion, the field studies demonstrated that it is feasible to use the three approaches to monitor quality and safety in maternity units. However, further work is required to use these data to enhance the quality and safety of care. Additionally, future work is needed to cover the other three dimensions of the PSMMF.
    • Development and Feasibility of a Measure of Self in Dementia

      Smith, Sarah J.; Oyebode, Jan R.; Surr, Claire A.; Bradley, Rosemary J.
      Methods A standardised measurement tool was developed by identifying aspects of self that can be measured, and research methods that are effective at investigating self in people without dementia. The measure consists of three sets of illustrated ‘I am…’ statements representing Activities, Traits and Physical Characteristics, and Relationships and Occupations. Participants were asked to (i) sort these according to whether each was ‘just like me’, ‘a bit like me’ or ‘not at all like me’ (ii) sort their ‘just like me’ choices to identify the statement most like them; (iii) describe memories associated with this statement. The measure was tested with 20 people with dementia to inform refinement. The refined measure was tested for reliability and validity by comparing results from five people with dementia and six age-matched people without dementia. Results Outcome measures were strength, complexity and quality of self and an ‘episodicity’ score reflecting the descriptive richness of memories. The initial administration to 20 people indicated that the measure was suitable for people with mild to moderate dementia, and the outcomes were meaningful and reliable. An ‘Observational Framework’ was developed to enable measurement of self via gestures and expressions of people with limited verbal abilities. The second study indicated that the new measure has good test-retest reliability, but convergent validity was not demonstrated. Participants with dementia demonstrated strength, complexity and quality of self scores comparable to participants without dementia. The results suggest that providing visual cues bypasses the cognitive processes required for effortful recall.
    • Optimum power transfer in RF front end systems using adaptive impedance matching technique

      Alibakhshikenari, M.; Virdee, B.S.; Azpilicueta, L.; See, C.H.; Abd-Alhameed, Raed A.; Althuwayb, A.A.; Falcone, F.; Huyen, I.; Denidni, T.A.; Limiti, E. (Nature Publishing Group, 2021-06)
      Matching the antenna’s impedance to the RF-front-end of a wireless communications system is challenging as the impedance varies with its surround environment. Autonomously matching the antenna to the RF-front-end is therefore essential to optimize power transfer and thereby maintain the antenna’s radiation efficiency. This paper presents a theoretical technique for automatically tuning an LC impedance matching network that compensates antenna mismatch presented to the RF-front-end. The proposed technique converges to a matching point without the need of complex mathematical modelling of the system comprising of non-linear control elements. Digital circuitry is used to implement the required matching circuit. Reliable convergence is achieved within the tuning range of the LC-network using control-loops that can independently control the LC impedance. An algorithm based on the proposed technique was used to verify its effectiveness with various antenna loads. Mismatch error of the technique is less than 0.2%. The technique enables speedy convergence (< 5 µs) and is highly accurate for autonomous adaptive antenna matching networks.
    • Analysis of the combinatory effect of uniaxial electrical and magnetic anisotropy on the input impedance and mutual coupling of a printed dipole antenna

      Bouknia, M.L.; Zebiri, C.; Sayad, D.; Elfergani, I.; Alibakhshikenari, M.; Rodriguez, J.; Abd-Alhameed, Raed A.; Falcone, F.; Limiti, E. (IEEE, 2021)
      The main objective of this work is to investigate the combinatory effects of both uniaxial magnetic and electrical anisotropies on the input impedance, resonant length and the mutual coupling between two dipoles printed on an anisotropic grounded substrate. Three different configurations: broadside, collinear and echelon are considered for the coupling investigation. The study is based on the numerical solution of the integral equation using the method of moments through the mathematical derivation of the appropriate Green’s functions in the spectral domain. In order to validate the computing method and evaluated Matlab® calculation code, numerical results are compared with available literature treating particular cases of uniaxial electrical anisotropy; good agreements are observed. New results of dipole structures printed on uniaxial magnetic anisotropic substrates are presented and discussed, with the investigation of the combined electrical and magnetic anisotropies effect on the input impedance and mutual coupling for different geometrical configurations. The combined uniaxial (electric and magnetic) anisotropies provide additional degrees of freedom for the input impedance control and coupling reduction.

The article contains data that shows the resilience of this service during the Covid19 pandemic and provides evidence that this type of service is beneficial for patient care.
    • 3D-FISH analysis of the spatial genome organization in skin cells in situ

      Mardaryev, Andrei N.; Fessing, Michael Y. (2020-04)
      Spatial genome organization in the cell nucleus plays a crucial role in the control of genome functions. Our knowledge about spatial genome organization is relying on the advances in gene imaging technologies and the biochemical approaches based on the spatial dependent ligation of the genomic regions. Fluorescent in situ hybridization using specific fluorescent DNA and RNA probes in cells and tissues with the spatially preserved nuclear and genome architecture (3D-FISH) provides a powerful tool for the further advancement of our knowledge about genome structure and functions. Here we describe the 3D-FISH protocols allowing for such an analysis in mammalian tissue in situ including in the skin. These protocols include DNA probe amplification and labeling; tissue fixation; preservation and preparation for hybridization; hybridization of the DNA probes with genomic DNA in the tissue; and post-hybridization tissue sample processing.
    • Modelling corporate bank accounts

      Fry, John; Griguta, V.; Gerber, L.; Slater-Petty, H.; Crockett, K. (2021)
      We discuss the modelling of corporate bank accounts using a proprietary dataset. We thus offer a principled treatment of a genuine industrial problem. The corporate bank accounts in our study constitute spare, irregularly-spaced time series that may take both positive and negative values. We thus builds on previous models where the underlying is real-valued. We describe an intra-monthly effect identified by practitioners whereby account uncertainty is typically lowest at the beginning and end of each month and highest in the middle. However, our theory also allows for the opposite effect to occur. In-sample applications demonstrate the statistical significance of the hypothesised monthly effect. Out-of-sample forecasting applications offer a 9% improvement compared to a standard SARIMA approach.
    • Targeting the TGF-β signaling pathway for resolution of pulmonary arterial hypertension

      Sharmin, Nahid; Nganwuchu, Chinyere C.; Nasim, Md. Talat (2021)
      Aberrant transforming growth factor-β (TGF-β) signaling activation is linked to pulmonary arterial hypertension (PAH). BMPR2 mutations perturb the balance between bone morphogenetic protein (BMP) and TGF-β pathways, leading to vascular remodeling, narrowing of the lumen of pulmonary vasculature, and clinical symptoms. This forum highlights the association of the TGF-β pathway with pathogenesis and therapeutic approaches.
    • The role of peer effects in corporate employee welfare policies

      Rind, A.A.; Akbar, Saeed; Boubaker, S.; Lajili-Jarjir, S.; Mollah, S. (Wiley, 2021)
      This paper investigates the role of peer effects in the employee welfare policies of organizations. Using US panel data for a sample of 11,451 firm-year observations from 1996 to 2017, we find that firms’ employee welfare decisions are driven by their peers and show that peer firms play a significant role in defining corporate employee welfare policies. Our findings are robust to various sensitivity checks, including alternative definitions of employee welfare, alternative peer proxies, and several identification strategies. Our additional analysis shows that herding behavior is prevalent in followers, who mimic leaders' behavior, but we do not find any such relationship for industry leaders. Further, we show the evidence suggesting that mimetic and normative isomorphic pressures are driving the peer effects. Finally, we document the economic consequence of peer mimicking in employee welfare policies. Our findings on firms’ peer effects and herding behavior have policy implications.
    • An Investigation of Group Key Management with Mobility Protocol for 5G Wireless Mobile Environment. A Case analysis of group key management security requirements with respect to wireless mobile environment of different proposed solutions

      Abd-Alhameed, Raed A.; Shepherd, Simon J.; Noras, James M.; Eya, Nnabuike N. (University of BradfordSchool of Engineering and Informatics, 2019)
      Group communication, security and 5G technology present a unique dimension of challenges and security remains crucial in the successful deployment of 5G technology across different industry. Group key management plays a vital role in secure group communication. This research work studies various group key management schemes for mobile wireless technology and then a new scheme is proposed and evaluated. The main architecture is analysed, while the components and their roles are established, trust and keying relationships are evaluated, as well as detailed functional requirements. A detailed description of the main protocols required within the scheme is also described. A numerical and simulation analysis is employed to assess the proposed scheme with regards to fulfilling the security requirement and performance requirements. The impact of group size variation, the impact of mobility rate variation are studied with regards to the average rekeying messages induced by each event and 1-affects-n phenomenon. The results obtained from the simulation experiments show that the proposed scheme outperformed other solutions with a minimal number of rekeying messages sent and less number of affected members on each event. The security requirements demonstrate that backward and forward secrecy is preserved and maintained during mobility between areas. Finally, the research work also proposes a 5G-enabled software-defined multicast network (5G-SDMNs), where software-defined networking (SDN) is exploited to dynamically manage multicast groups in 5G and mobile multicast environment. Also, mobile edge computing (MEC) is exploited to strengthen network control of 5G-SDMN.
    • Two-dimensional turbulent burst examination and angle ratio utilization to detect scouring/sedimentation around mid-channel bar

      Khan, M.A.; Sharma, N.; Pu, Jaan H.; Aamir, M.; Pandey, M. (Springers, 2021-07)
      River morphological dynamics are complex phenomena in natural and environmental flows. In particular, the sediment transport around braid mid-channel bars has not gained enough understanding from previous research. The effect of submergence ratio on the turbulence behavior in the proximity of the bar has been investigated in this study. The spatial distribution of turbulent flow in the proximity of bar has been studied by plotting the depth-averaged two-dimensional contours of turbulent kinetic energy. The high value of TKE has been observed in regions just downstream from the bar. It is due to the vortex shedding occurring in that region. The interaction of sweep and ejection events have been analyzed using the parameter Dominance Function obtained from the ratio of occurrence probability of ejection events to the occurrence probability of sweep events. This outcome indicates that the depth averaged parameter Dominance Function has successfully predicted the high scouring region which makes it an ideal parameter for analyzing the scour phenomena in real-world water management projects. The high scouring zone lies in the close proximity of the bar. This shows that the scouring effect from the bar is limited to its close region. The magnitude of scouring occurring at the upstream region of the bar also increases with the increment of submergence ratio. The relationship of quadrant event inclination angles with the sediment transport occurring in the proximity of bar has been also studied, where an Angle Ratio parameter has been utilized for linking the bed elevation change with the inclination angle. The results indicate that the AR parameter has been successfully tested in this study to show its competence to represent the turbulent burst-induced bed sedimentation and scouring.
    • Social media analytics for end-users’ expectation management in information systems development projects

      Banerjee, S.; Singh, J.P.; Dwivedi, Y.K.; Rana, Nripendra P. (2021)
      This exploratory research aims to investigate social media users’ expectations of information systems (IS) products that are conceived but not yet launched. It specifically analyses social media data from Twitter about forthcoming smartphones and smartwatches from Apple and Samsung, two firms known for their innovative gadgets. Tweets related to the following four forthcoming IS products were retrieved from 1st January 2020 to 30th September 2020: (1) Apple iPhone 12 (6,125 tweets), (2) Apple Watch 6 (553 tweets), (3) Samsung Galaxy Z Flip 2 (923 tweets), and (4) Samsung Galaxy Watch Active 3 (207 tweets). These 7,808 tweets were analysed using a combination of the Natural Language Processing Toolkit (NLTK) and sentiment analysis (SentiWordNet). The online community was quite vocal about topics such as design, camera and hardware specifications. For all the forthcoming gadgets, the proportion of positive tweets exceeded that of negative tweets. The most prevalent sentiment expressed in Apple-related tweets was neutral but in Samsung-related tweets was positive. Additionally, it was found that the proportion of tweets echoing negative sentiment was lower for Apple compared with Samsung. This paper is the earliest empirical work to examine the degree to which social media chatter can be used by project managers for IS development projects, specifically for the purpose of end-users’ expectation management.
    • The optimal configuration of IT-enabled dynamic capabilities in a firm’s capabilities portfolio: A strategic alignment perspective

      Majhi, S.G.; Anand, A.; Mukherjee, A.; Rana, Nripendra P. (2021-05)
      Although IT-enabled dynamic capabilities (ITDCs) add value to firms operating in turbulent and rapidly changing environments, firms face several challenges in developing, deploying, and maintaining the right portfolio of ITDCs. Since ITDCs are not uniformly advantageous, firms need to make strategic decisions in order to accomplish the complex task of achieving optimal ITDC configurations. This conceptual paper draws on the strategic alignment perspective to identify the optimal configuration of ITDCs for a firm based on its business strategy orientation indicated by the Miles and Snow typology. This paper first explicates the theoretically ideal configurations of ITDCs based on the competitive strategy patterns associated with each Miles and Snow archetype and then develops a model for measuring the strategic fit of ITDCs. This paper contributes to the literatures on ITDCs and strategic alignment by identifying optimal ITDC configurations and by conceptualizing the strategic fit of ITDCs respectively.
