AbstractThe relationships between structure and function in human knee femoral cartilage are not well-known at different stages of osteoarthritis. Thus, we characterized the depth-dependent composition and structure of normal and osteoarthritic human femoral condyle cartilage (n = 47) and related them to their viscoelastic and constituent-specific mechanical properties. We observed that, in superficial cartilage, the collagen network disorganization and proteoglycan loss were associated with the smaller initial fibril network modulus (collagen pretension). Furthermore, the proteoglycan loss was associated with the greater strain-dependent fibril network modulus (a measure of nonlinear mechanical behavior). The proteoglycan loss was also associated with greater cartilage viscosity at a low loading frequency (0.005 Hz), while the disorganization of the collagen network was associated with greater cartilage viscosity at a high loading frequency (1 Hz). Our results suggest that proteoglycan degradation and collagen disorganization reduce the pretension of the collagen network while proteoglycan degradation also increases the nonlinear mechanical response of the collagen network. Further, the results also highlight that proteoglycan degradation and collagen disorganization increase the viscosity of cartilage, but their contribution to increased viscosity occurs in completely different loading frequencies.

Published: May 2022

ABSTRACTSucculent plants possess traits that allow them to complete physiological functions under extreme environments and root are at the frontline of the stress: the drying soil. Previous works in succulent plants have reported the extraordinary reversible mechanism of root shrinkage that disconnects plants from drying soils, reestablishing the hydraulic connection when water availability is restored. Yet, this rectifier-like mechanism would require complex biomechanical and hydraulic control at organ, tissue, and cell level. In here we evaluated the changes in hydraulic and mechanical behavior of Opuntia fine roots under extreme drought stress. Using a combination of techniques, we found that fine roots get more elastic as drought stress gets more extreme, allowing cells to modify their shape while preventing permanent damage. Furthermore, we found abrupt decreases in Lpr, that coincided with increased root shrinkage, suberin deposition and structural damage inside the endodermis via lacunae formation and possibly cell wall folding. Our data suggest that, in drought stressed succulent plants, the biomechanics of organs, tissues, and possibly cell walls are deeply coupled with belowground hydraulics, highlighting the need to continue working on deciphering the physiological mechanism that governs the interplay between mechanics and hydraulics at cell level in fine roots during drought.

AbstractThe amplitude envelope of speech carries crucial low-frequency acoustic information that assists linguistic decoding. The sensory-neural Temporal Sampling (TS) theory of developmental dyslexia proposes atypical encoding of speech envelope information <10 Hz, leading to atypical phonological representations. Here a backward linear TRF model and story listening were employed to estimate the speech information encoded in the electroencephalogram in the canonical delta, theta and alpha bands by 9-year-old children with and without dyslexia. TRF decoding accuracy provided an estimate of how faithfully the children’s brains encoded low-frequency envelope information. Between-group analyses showed that the children with dyslexia exhibited impaired reconstruction of speech information in the delta band. However, when the quality of speech encoding for each child was estimated using child-by-child decoding models, then the dyslexic children did not differ from controls. This suggests that children with dyslexia encode neither “noisy” nor “normal” representations of the speech signal, but different representations.

Published: May 2022

SummaryMicrobial production of intracellular compounds can be engineered by, for example, redirecting the carbon flux towards products and increasing the cell size. Potential engineering strategies include exploiting clustered regularly interspaced short palindromic repeats interference (CRISPRi)-based tools for controlling gene expression. Here, we applied CRISPRi for engineering Acinetobacter baylyi ADP1, a model bacterium for synthesizing intracellular storage lipids, namely wax esters. We firstly established an inducible CRISPRi system for strain ADP1, which enables tightly controlled repression of target genes. We then targeted the glyoxylate shunt to redirect carbon flow towards wax esters. Secondly, we successfully employed CRISPRi for modifying cell morphology by repressing ftsZ, an essential gene required for cell division, in combination with targeted knock-outs to generate significantly enlarged filamentous or spherical cells, respectively. The engineered cells sustained increased wax ester production metrics, demonstrating the potential of cell morphology engineering in the production of intracellular lipids.
Architectural language of the Southern Fujianese traditional Chinese temple timber frame structure in West Malaysia: a cultural semiotics analysis
Authors: Koh Jing Hao , Lim Chee Men 
Published: May 2022

PurposeThis paper examines the relationship between traditional timber frame structure and the diasporic identity of the Southern Fujianese Chinese community in West Malaysia. It analyses the cultural semiotics of Southern Fujianese traditional Chinese temple timber frame structure architectural language. This study addresses the under-examined domain of Chinese cultural identity representation through the architecture of traditional Chinese temples in Malaysia. It seeks to understand its underlying structure and process involved in revealing its disposition within the cultural phenomena from the perspective of Chinese cultural semiotics.Design/methodology/approachSelected Southern Fujianese traditional Chinese temples in West Malaysia built between the 18th to the 19th century that retain the traditional timber frame structure were investigated through field survey and focused publication review. Historical interpretive analysis and typological analysis supplement the cultural semiotics analysis to assess the timber frame structure attributes concerning architectural language expressions.FindingsFindings reveal that the architectural language signifiers of the structural disposition of the timber framework and its corresponding formal articulation establish a clear statement of the Southern Fujian Chinese cultural identity.Originality/valueThe evaluation of the cultural identity signifiers helps to understand the underlying structure and process of the Chinese cultural semiotics in architecture. Results of this research substantiate the significance of timber frame structure in preserving the architectural heritage of the Southern Fujianese traditional Chinese temples. They provide important references for conservation and cultural studies of such building typology.
Reducing the constraints to school access and progress: assessing the effects of a scholarship program in rural Malawi
Authors: Hunsaker Stephen , Baum Donald R. , Ducos Katy 
Published: May 2022

PurposeThe study aims to provide insight on the potential effectiveness of demand-side financing for catalyzing improved educational outcomes in Malawi; and, given the extent of cost-related constraints to school contexts in other low-income countries, the results have relevance for education policy decisions more broadly.Design/methodology/approachThis study utilizes a non-equivalent groups research design to compare the educational experiences and outcomes of two student groups – those who did and those who did not receive a needs-based scholarship to attend secondary school and college in the Dowa, Kasungu, and Lilongwe Districts of Malawi. The authors assess impacts across a range of short and medium-term outcomes, including: school attendance, withdrawal, attainment, graduation, employment status, employment quality, and post-schooling income.FindingsThe scholarship substantially reduces the household cost of participation in school, and reduces the distance travelled to school. As a result, scholarship recipients attain between 1 and 1.5 years of additional schooling and graduate at higher rates. In terms of post-schooling outcomes, recipients are in higher wage-earning occupations after leaving school. Overall, results suggest that scholarships are an effective demand-side strategy for improving educational attainment, progression, and potentially longer-term labor market outcomes.Originality/valueThe study adds new evidence on policy approaches for expanding access to educational opportunities and increasing labor market outcomes in a context (Malawi specifically and sub-Saharan Africa more broadly) where evidence on such demand-side interventions is still growing.

PurposeUnderstanding students’ preferences for teaching and course design is important for educators in higher education when planning courses and teaching activities. The purpose of this study was to explore changes in occupational therapy students’ preferences for teaching and courses across the three-year study program.Design/methodology/approachA total of 263 students participated in a longitudinal study, where preferences were measured with the Approaches and Study Skills Inventory for Students. The data were analyzed with linear mixed effect models for repeated measures.FindingsThe results indicated no significant changes in preferences for courses and teaching over the three-year period. Also, there were no significant differences between the six involved study programs. Preferences for the courses and teaching type “supporting understanding” were associated with higher age and higher study effort. Preferences for the courses and teaching type “transmitting information” were associated with lower age and female gender.Originality/valueIn summary, the findings of this study suggest that preferences for teaching and courses are stable and may be challenging to alter during a three-year undergraduate study program.

Authors: Leong Lai-Ying , Hew Jun-Jie , Wong Lai-Wan , Lin Binshan 
Published: May 2022

PurposeMobile payment (m-payment) has existed for over 25 years; however, there is no standard framework to guide scholars and practitioners in advancing m-payment research in the digital accelerated era. With this, this study aims to develop an m-payment framework and to analyse the evolution of m-payment research from 1997 to 2021. These were achieved by identifying the motor themes, basic and transversal themes, the emerging/declining themes and the highly developed but isolated themes. In addition, the publication trends of m-payment research were also identified.Design/methodology/approachA total of 1,999 articles of m-payment were identified from the Scopus database and 8,125 keywords were grouped into 483 word groups for the co-word analysis. Thematic networks were generated based on density and centrality. Performance analysis was performed on the themes of the four quadrants in the strategic diagrams. The m-payment framework was then developed based on the evolution map and a practical guide was built from the framework.FindingsThe m-payment framework consists of four dimensions, namely behaviour, technology, risk, and context. Some themes were declining while at the same time, m-payment remains strongly relevant and can stand the test of time. Several new themes have emerged in the 2013–2021 sub-periods.Research limitations/implicationsThis study is limited in that the study only investigates from the context of m-payment.Practical implicationsThis study has provided a research framework (i.e. the m-payment framework) with a practical guide for scholars and practitioners to refer to, thus enabling them to embark on future studies without any hassle. The m-payment framework was developed based on empirical data using science mapping analysis of 1,999 articles.Social implicationsThe proposed m-payment research framework contributes towards more understanding of m-payment ten, usage amongst consumers and thus will help to reduce the rate of COVID-19 infection because m-payment is a contactless payment. Hence, the study may help in creating a safer and healthier society amid the unprecedented pandemic.Originality/valueThis study developed the m-payment framework based on empirical co-word analysis. A practical guide to extending the framework is also provided to guide the scholars and practitioners. Moreover, the evolution map for m-payment was created to understand the evolution of m-payment research. Practitioners may conduct market studies to unveil the factors that contribute to consumers' behaviours in m-payment in order to gain more understanding of the reasons behind their behaviours.
Integrating the dialectic perspectives of resource-based view and industrial organization theory for competitive advantage – a review and research agenda
Authors: Nayak Bishwajit , Bhattacharyya Som Sekhar , Krishnamoorthy Bala 
Published: May 2022

PurposeAcademic dialogue related to ‘organizational performance’ in strategic management has primarily centred around the industrial organization theory (IO) and resource-based view (RBV). Both perspectives, though conceptually dialectic, have served as primary competing theories governing research studies in the domain of strategic management. However, the confluence of these theoretical perspectives has not been adequately explored to advance a shared view of competitive advantage. This study aims to explore the likelihood of embedded commonalities between RBV and IO.Design/methodology/approachA bibliometric analysis was conducted to visualize the intellectual map of studies and knowledge development encompassing these theories. This was followed by a comprehensive literature review to understand how the business environment (BE) and organizational capabilities have contributed towards attaining competitive advantage.FindingsThis study established that connecting the intellectual boundaries of these theoretical perspectives would facilitate better comprehension of the processes and outcomes in organizations. Integrating the knowledge emerging out of this methodological blend, a convergence framework connecting the intellectual boundaries of both theories was presented.Practical implicationsThe framework that emerged from this study would help in better understanding of organizational behaviour from a dual theoretical lens. It would also motivate future studies to consider RBV and IO as complementary theories rather than the current narrative of competing theories.Social implicationsThis study added to the efforts to achieve equilibrium between the BE and internal capabilities of organizations so as to maximize positive social externalities.Originality/valueThis study contributed to the limited attempts to leverage shared knowledge from a dual perspective using a comprehensive literature review in sequential combination with bibliometric analysis.
Family social capital as a driver to leverage challenged transgenerational entrepreneurship
Authors: Iturrioz-Landart Cristina , Aragón-Amonarriz Cristina , Cabrera-Suárez M. Katiuska 
Published: May 2022

PurposeThe purpose of the study is to unveil the key role of family social capital (FSC) as a driver for transgenerational entrepreneurship (TE) in the specific contexts of challenged successor-driven entrepreneurship.Design/methodology/approachThe paper adopts a multi-case study methodology. Guided by three theoretical propositions, three TE case studies are analyzed. Drawing on ten in-depth interviews with at least three different informants from each intra-family succession case study, evidence about this particularly complex phenomenon was obtained.FindingsThe paper highlights the effect of FSC as the key familiness driver to leverage challenged successor-driven entrepreneurship. The paper underscores the systemic and dynamic network of multiple exchanges required to construct successor’s own pool of knowledge resources and to support familiness and thus the competitive advantage of the family firm (FF).Practical implicationsDifferent scenarios are illustrated, and specific lessons are provided for successors and families that face TE opposition in intra-family succession, regarding the restoration of damaged FSC and involving non-family stakeholders in the successor-driven entrepreneurship. In these cases, opposition to successor-driven entrepreneurship may help to develop successor’s leadership abilities.Originality/valueFocusing on a specific intra-family succession context where successor-driven entrepreneurial initiatives face stakeholder opposition, the paper highlights the specific role played by FSC in the successor knowledge construction in specific contexts of challenged intra-family succession.
Board role performance and sustainability reporting practices: managerial perception-based evidence from Uganda
Authors: Tumwebaze Zainabu , Bananuka Juma , Orobia Laura A. , Kinatta Moses Munyami 
Published: May 2022

Purpose
The purpose of this study is threefold: first, to examine among the board role performance attributes, which ones are critical for sustainability reporting practices; second, to establish the relationship between the overall board role performance and sustainability reporting practices; and third, to establish the relationship between board role performance and the three dimensions of sustainability reporting practices.

Design/methodology/approach
This study is correlational as it aims to establish relationships. Data were collected within a period of one year. Usable questionnaires were received from 48 financial services firms in Uganda.

Findings
On average, financial services firms in Uganda follow the Global Reporting Initiative sustainability reporting standards to the extent of 64%. The study results also indicate that board role performance is significantly associated with sustainability reporting practices. Board role performance is more associated with social sustainability reporting than environmental and economic sustainability reporting. In terms of board roles, service role is more associated with the sustainability reporting practices than the control and strategic role of the board.

Practical implications
The board has to provide the necessary support to management by passing decisions aimed at improving sustainability reporting practices and providing the necessary resources such as budgets for training of staff in sustainability reporting standards. Policymakers may require companies to prepare sustainability reports annually.

Originality/value
This study provides insights on the initial understanding of the link between board role performance and sustainability reporting practices. This study sheds more light on the relationship between board role performance and the dimensions of sustainability reporting. The study further enlightens the academic community and practice on which board roles are critical for enhanced sustainability reporting. This study therefore posts that it is no longer a matter of having board members but, rather, the role these board members play.
