Envisioning the Indigenised university for sustainable development
Authors: Mbah Marcellus Forh , Ajaps Sandra , Johnson Ane Turner , Yaffa Sidat 
Published: May 2022

Purpose
While the possibility of a university fostering sustainable development is present in the extant literature and policy documents, the idea still warrants further consideration. Therefore, this paper aims to identify the nature and outcomes of the university’s engagement with Indigenous communities and perceptions of Indigenous knowledge systems in both academic and non-academic activities, and what might be required to foster the university’s contributions towards sustainable development.

Design/methodology/approach
A qualitative case study of the only public university in The Gambia was conducted, including non-university actors. Interviews and focus group discussion methods were used, and these enabled close collaboration between researchers and participants, and the latter were empowered to describe their perceptions of reality.

Findings
Three major sets of findings emerged from the analysis of the transcripts from interviews and focus group discussions with the university and community members. These are the limited nature of and outcomes from university–community engagement, the sustainable outcomes of Indigenous practices and ideas for Indigenising university engagement for sustainable development.

Practical implications
Particular implications of the study that underpins this paper can be underscored; these include: a contribution to the literature on ways of connecting Indigenous communities with universities, and to a conceptualisation of the Indigenised university; a provision of insights into the connectivity between university community engagement, Indigenous knowledge systems and sustainable development; the creation of a context for subsequent studies on practical steps that universities might take in the direction of epistemic justice and sustainable development for all; and heightening the intractability of theoretical and philosophical issues of epistemology, knowledge ecology and epistemological justice, as they reveal themselves in practice, in complex situations.

Originality/value
Matters of the university reaching out to Indigenous peoples have yet to find their way into conceptualisations of the university for sustainable development. This paper addresses this gap in the existing literature by advancing possibilities for the Indigenised university for sustainable development to emerge.

Authors: Oborah James Omatule 
Published: May 2022

PurposeThere is considerable efforts by government and various agencies towards the development of information and communication technology (ICT) skills in the developing nations. The efforts include the procurement and deployment of ICT devices and curriculum development; but, these are not yielding the ultimate results as the digital divide continue to widen regionally. This calls for innovation in teaching and learning in ICT. The study assessed the effectiveness of infusion approach to teaching and learning in the tertiary education level. This approach utilises a framework and student-centred approach for which its effectiveness as an instructional delivery was tested for efficacy.Design/methodology/approachThe study adopted quasi-experimental design with pretest and posttest comparison to assess the treatment given. Performance was measured quantitatively through online assessment.FindingsThe results showed a phenomenal effectiveness of infusion approach to teaching and learning of general ICT skills as the participants achieved very high performance at the end of the instructional period.Research limitations/implicationsThis research is based on general ICT skills and covers a regional cross-section of Nigeria.Practical implicationsAdoption of infusion approach to teaching and learning in ICT would close the prevailing knowledge gaps in the development of ICT skills.Social implicationsThis infusion approach would close the prevailing digital divide, thereby enhancing societal well-being.Originality/valueThis is a novel approach to the development of ICT skills, which would enhance teaching and learning in ICT.

Published: May 2022

PurposeHow to extract useful information from a very large volume of literature is a great challenge for librarians. Topic modeling technique, which is a machine learning algorithm to uncover latent thematic structures from large collections of documents, is a widespread approach in literature analysis, especially with the rapid growth of academic literature. In this paper, a comparison of topic modeling based literature analysis has been done using full texts and abstracts of articles.Design/methodology/approachThe authors conduct a comparison study of topic modeling on full-text paper and corresponding abstract to assess the influence of the different types of documents been used as input for topic modeling. In particular, the authors use the large volumes of COVID-19 research literature as a case study for topic modeling based literature analysis. The authors illustrate the research topics, research trends and topic similarity of COVID-19 research by using Latent Dirichlet allocation (LDA) and topic visualization method.FindingsThe authors found 14 research topics for COVID-19 research. The authors also found that the topic similarity between using full-text paper and corresponding abstract is higher when more documents are analyzed.Originality/valueFirst, this study contributes to the literature analysis approach. The comparison study can help us understand the influence of the different types of documents on the results of topic modeling analysis. Second, the authors present an overview of COVID-19 research by summarizing 14 research topics for it. This automated literature analysis can help specialists in the health and medical domain or other people to quickly grasp the structured morphology of the current studies for COVID-19.
Board dynamics and board tasks empowered by women on boards: evidence from Italy
Authors: Slomka-Golebiowska Agnieszka , De Masi Sara , Paci Andrea 
Published: May 2022

Purpose
This study aims to examine the effects of board dynamics produced by reaching a certain proportion of women on board tasks (monitoring, strategy and advisory).

Design/methodology/approach
Using a panel of 35 listed companies belonging to FTSE-MIB index, for the years 2008–2015, the hypotheses can be tested by applying random effect regressions. The introduction of gender board quota law in Italy has created a quasi-natural experiment that is applied in the study.

Findings
This research provides evidence that reaching 33% women on boards, which is the threshold mandated by the Italian gender board quota law, makes a difference for strategy tasks but not for monitoring tasks. This proportion of women on boards creates the board dynamics necessary to empower all board members, allowing the varied knowledge, skills, backgrounds and personal qualities to be leveraged and used in strategy tasks. For monitoring tasks, obtaining a proportion of 20% women on boards, as a first threshold enforced by the law, is enough to voice their opinion during board meetings and challenge management.

Originality/value
The results show that each set of board tasks requires different dynamics trigged by a specific proportion between a minority (women) and a dominant subgroup (men). To enhance monitoring tasks performance, it is enough to reach a proportion between men and women which makes the women less isolated and more inclined to speak up during the board meetings. In the case of strategy tasks, the improved performance is achieved when the dominant group enticed to hear women’s opinions and responsive to various perspectives. This paper expands the debates going beyond monitoring tasks, showing the importance of board dynamics for engagement in strategy and advisory tasks.
Design, analysis and method of foot trajectory generation for quadruped robots in swing-stance phase
Authors: Biswal Priyaranjan , Mohanty Prases Kumar 
Published: May 2022

Purpose
Legged walking robots have numerous advantages over the wheel or tracked robots due to their strong operational ability and exposure to the complex environment. This paper aims to present details about the mechanical formation and a new conceptual elliptical trajectory generation discussed throughout the paper of the quadruped robot.

Design/methodology/approach
Initially, a realistic CAD model of the four-legged robot is developed in Solidwork-2019. The proposed model’s forward and inverse kinematics equations are deduced using Denavit–Hartenberg parameters. Based on geometry and kinematics, manipulability and obstacle avoidance are investigated. A method of galloping trajectory is proposed for aiming the increase of upright direction impulse, which is produced by ground reaction force at each step frequency. Furthermore, the locomotion equation of the ellipse trajectory is derived by setting transition angle polynomial of free-fall phase, stance phase and swing phase and the constraints.

Findings
Finally, a successive simulation on a 2D sagittal plane is performed to check and verify the usefulness of the proposed trajectory. Before the development of the full quadruped, a single prototype leg is generated for experimental verification of the dynamic simulations.

Originality/value
The proposed trajectory is novel in that it uses force tracking control, which is intended to improve the quadruped robot’s robustness and stability.
Enhancing fluxes through the mevalonate pathway in Saccharomyces cerevisiae by engineering the HMGR and β‐alanine metabolism

Published: May 2022

SummaryMevalonate (MVA) pathway is the core for terpene and sterol biosynthesis, whose metabolic flux influences the synthesis efficiency of such compounds. Saccharomyces cerevisiae is an attractive chassis for the native active MVA pathway. Here, the truncated form of Enterococcus faecalis MvaE with only 3‐Hydroxy‐3‐methylglutaryl coenzyme A reductase (HMGR) activity was found to be the most effective enzyme for MVA pathway flux using squalene as the metabolic marker, resulting in 431‐fold and 9‐fold increases of squalene content in haploid and industrial yeast strains respectively. Furthermore, a positive correlation between MVA metabolic flux and β‐alanine metabolic activity was found based on a metabolomic analysis. An industrial strain SQ3‐4 with high MVA metabolic flux was constructed by combined engineering HMGR activity, NADPH regeneration, cytosolic acetyl‐CoA supply and β‐alanine metabolism. The strain was further evaluated as the chassis for terpenoids production. Strain SQ3‐4‐CPS generated from expressing β‐caryophyllene synthase in SQ3‐4 produced 11.86 ± 0.09 mg l−1 β‐caryophyllene, while strain SQ3‐5 resulted from down‐regulation of ERG1 in SQ3‐4 produced 408.88 ± 0.09 mg l−1 squalene in shake flask cultivations. Strain SQ3‐5 produced 4.94 g l−1 squalene in fed‐batch fermentation in cane molasses medium, indicating the promising potential for cost‐effective production of squalene.
Measuring the American farm size distribution
Authors: Lacy Katherine , Orazem Peter F. , Schneekloth Skyler 
Published: May 2022

AbstractThis paper develops a measure of farm size as a share‐weighted sum of farm sizes, called the Share Weighted Size Index (SWSI), which introduces new evidence of farm consolidation from 1959 to 2017. Our Share Weighted Size Index provides more reasonable estimates of the entire farm size distribution than simple averages and is useful for comparing farm size across crops at one point in time or for comparing farm sizes for a given crop over time. Although previous measures have relied on confidential or hard‐to‐access farm‐level records, the Share Weighted Size Index is derived exclusively from publicly available Census of Agriculture data. Unlike average farm size, the Share Weighted Size Index reveals consistent evidence of rising farm size, the importance of returns to scale for most commodities, and the rising importance of specialization on a small number of crops within farms. Contrary to past studies that argued rising off‐farm wages increase farm size, we find evidence that proximity to off‐farm opportunities results in smaller farms.

AbstractBackgroundThe prevalence of elderly patients with resectable colorectal peritoneal metastases (CRPM) is increasing. This study aimed to compare short and long‐term outcomes of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for CRPM in patients above and below 70 years of age.MethodsThis was a retrospective, 10‐year analysis of 90‐day major morbidity and mortality, and long‐term survival.ResultsThirty‐two (21.3%) of 150 consecutive patients who underwent CRS and HIPEC during the study period were aged 70 and older. PCI (P = 0.04), perioperative chemotherapy use (P < 0.01) and organ resections (rectum P = 0.04, diaphragm P = 0.03) were less in the over 70 group. There was no significant differences in major morbidity (P = 0.19) and mortality (P = 0.32). There was also no difference in 5‐year overall survival (OS) (≥70: 26% vs. <70: 39%; P = 0.68) and disease‐free survival (DFS) (≥70: 25% vs. <70: 14%; P = 0.22). Age above 70 was not independently associated with worse OS (HR 1.55, P = 0.20) and DFS (HR 1.07, P = 0.81).ConclusionThe surgical management of CRPM appears safe and feasible in this elderly population. Appropriate selection of elderly patients for such radical intervention is reinforced by the comparable survival with those under 70.

AbstractPurposeTo investigate the effect of polyquaternium‐1 (PQ)‐preserved and benzalkonium chloride (BAK)‐preserved travoprost eye drops on viability of primary human conjunctival goblet cell (GC) cultures and on secretion of mucin and cytokines. Furthermore, to evaluate the physicochemical properties of the branded travoprost eye drop Travatan® and available generics.MethodsThe effect of travoprost eye drops was evaluated on GC cultures. Cell viability was assessed through lactate dehydrogenase (LDH) and tetrazolium dye (MTT) colorimetric assays. Mucin secretion was evaluated by immunohistochemical staining. Secretion of interleukin (IL)‐6 and IL‐8 was measured using BD Cytometric Bead Arrays. pH, viscosity, droplet mass, osmolality and surface tension were measured for all included eye drops.ResultsIn the LDH assay, BAK travoprost caused significant GC loss after 2 hrs of incubation compared to the control. PQ travoprost caused no GC loss at any time point. Both PQ‐ and BAK travoprost caused secretion of mucin to the cytoplasma. No difference in IL‐6 and IL‐8 secretion was identified compared to controls. The pH values for the generics were lower (pH 6.0) than the pH value for Travatan (pH 6.7; p < 0.0001). The viscosity was lowest for Travatan, while the mean droplet mass was higher for Travatan (35 mg) than the generics (28–30 mg; p ≤ 0.0318). The osmolality and surface tension did not differ between the eye drops investigated.ConclusionBAK travoprost caused GC loss, indicating that PQ preservation may be preferable in treatment of glaucoma. Furthermore, physicochemical properties of branded and generic travoprost eye drops can not be assumed to be identical.

AbstractLoving‐kindness and compassion meditation (LKCM) was a promising intervention for improving life satisfaction, but previous findings have been inconsistent. The current study provides a systematic review and meta‐analysis, including 23 empirical studies on LKCM with life satisfaction as an outcome variable. The primary meta‐analysis indicated that LKCM significantly enhanced life satisfaction in pre‐post design (g = 0.312, k = 15, n = 451), but the significance disappeared in the additional meta‐analysis based on randomized controlled trials (g = 0.106, k = 6, n = 404). Moderator analyses found significant effects for type of control (i.e., the effects of LKCM were inferior to active control group, but superior to waitlist condition), but not for other moderators (i.e., participant type, previous meditation experience, specific protocol, components of LKCM, combination with mindfulness mediation, and intervention length). Narrative review identified self‐compassion and positive emotions as important mediators. The practice time of LKCM had indirect but not direct association with life satisfaction. The findings supported that LKCM is promising in increasing life satisfaction, but more studies are needed to investigate the effects with more rigorous designs. Future studies should investigate other potential mechanisms and clarify whether LKCM change the reality or the perception of life.
The many metaphysical commitments of secular clinical ethics: Expanding the argument for a moral–metaphysical proceduralism
Authors: Brummett Abram , Eberl Jason T. 
Published: May 2022

AbstractThe rich moral diversity of academic bioethics poses a paradox for the practice of giving moral recommendations in secular clinical ethics: How are ethicists to provide moral guidance in a pluralistic society? The field has responded to this challenge with a “procedural approach,” but defining this term stirs debate. Some have championed a contentless proceduralism, where ethicists work only to help negotiate resolutions among stakeholders without making any moral recommendations. Others have defended a moral proceduralism by claiming that ethicists should make moral recommendations that are grounded in bioethical consensus (e.g., relevant law, policy, professional consensus statements, and bioethics literature), which is secured using moral principles such as respect for persons or justice. In contrast, we develop a moral–metaphysical proceduralism by identifying many metaphysical commitments in points of secular bioethical consensus. The moral–metaphysical view of secular clinical ethics is important because it challenges the discipline to accept the substantive philosophical foundations required to support giving moral recommendations in a pluralistic context, which may lead to further insights about the nature of the field.
Co‐developmental trajectories of parental involvement: Relations to academic achievement and externalizing and internalizing problems among Chinese elementary schoolchildren
Authors: Guo Nan , Huebner Eugene Scott , Tian Lili 
Published: May 2022

AbstractBackgroundParental involvement is an important multi‐faceted factor in children's academic performance and school behaviour. However, most prior studies have involved cross‐sectional designs, with few studies exploring the co‐developmental nature of various parental involvement characteristics over time and their associations with children's academic achievement, externalizing, and internalizing problems.AimsThis study explored (a) co‐developmental trajectories of seven parental involvement characteristics in elementary schoolchildren, and (b) relations to children's academic achievement, externalizing, and internalizing problems.Sample and methodsA total of 3553 Chinese elementary schoolchildren (Mage = 9.90, SD = .72; 53.9% boys) completed relevant measures on 4 occasions at 6‐month intervals. Parallel process latent class growth modelling was used for examining study hypotheses.ResultsFour co‐developmental trajectories of parental involvement were identified: ‘High motivation and involvement’, ‘Low motivation and involvement’, ‘Incongruent motivation and involvement’, and ‘Incongruent motivation and high involvement’. The highest academic achievement and fewest externalizing and internalizing problems were observed for schoolchildren in the ‘High motivation and involvement’ class, followed by those who were in the ‘Incongruent motivation and high involvement’ and ‘Incongruent motivation and involvement’ classes, and finally, schoolchildren were the ‘Low motivation and involvement’ class.ConclusionsThe identification of heterogeneous trajectories with differential outcomes highlights the importance of individual differences considerations in understanding the co‐developmental patterns of parental involvement, suggesting that specific interventions need to be formulated for differing groups.
The dimensions underlying first impressions of older adult faces are similar, but not identical, for young and older adult perceivers
Authors: Twele Anita C. , Mondloch Catherine J. 
Published: May 2022

AbstractFirst impressions based on facial cues have the potential to influence how older adults (OAs), a vulnerable population, are treated by others. The present study used a data‐driven approach to examine dimensions underlying first impressions of OAs and whether those dimensions vary by perceiver age. In Experiment 1, young adult (YA) and OA participants provided unconstrained, written descriptions in response to OA faces. From these descriptors, 18 trait categories were identified that were similar, but not identical, across age groups. In Experiment 2, YA and OA participants rated OA faces on the trait words identified for their age group in Experiment 1. In separate principal components analyses, dimensions of sternness and confidence emerged for both groups. In Experiment 3, YA and OA participants rated these same faces on new words encompassing traits, emotion cues, and other appearance cues. Correlations between these ratings and factor scores showed that sternness is analogous to approachability for both age groups. Confidence is analogous to competence for both age groups and related to perceived age/health/attractiveness. Confidence was related to shyness for YAs but dominance for OAs. The current research has implications for a lifespan perspective on first impressions and informs functional accounts.
