Finite element method for analyzing effects of porous baffle on liquid sloshing in the two-dimensional tanks
Authors: Gao Hangduo , Yin Zhao , Liu Jun , Zang Quansheng , Lin Gao 
Published: October 2020

Purpose
The purpose of this paper is to analyze the liquid sloshing behaviors in two-dimensional tanks with various porous baffles under the external excitation.

Design/methodology/approach
Adopting the finite element method (FEM) and control variable method to study the impacts of the height, length, number, location, shape, porous-effect parameter of the porous baffle, the external load frequency and the shape of the tank on the liquid sloshing response.

Findings
The amplitude of the free surface can be reduced effectively when the baffle opening is appropriate. The anti-sway ability of the system increases in pace with the baffle’s height growing. Under the same conditions, the shapes of the baffles have an important effect on improving the anti-sway ability of the system.

Originality/value
As there exist the differences of the velocity potential between each side of the porous baffle, which means that there are two different velocity potentials at a point on the porous baffle, the conventional finite element modeling technologies are not suitable to be applied here. To deal with this problem, the points on the porous baffle are regarded as two nodes with the same coordinate to model and calculate.

Authors: R. Vijay , S. Manoharan , S. Nagarajan , D. Lenin Singaravelu 
Published: October 2020

Purpose
The purpose of this study is to deals with the effect of premixed dual metal sulfides (tin disulfide + iron disulfide) as a replacement for antimony trisulfide on the tribological performance of brake friction materials.

Design/methodology/approach
In this study, brake friction materials were developed by using premixed dual metal sulfides as a replacement for antimony trisulfide in the formulation. The brake friction materials were developed in the form of standard brake pads as per the industrial practice. Thermal stability was measured for varying ingredients and developed brake pads using thermogravimetric analysis. The physical, mechanical and thermal properties of the developed brake pads were tested as per the industrial standards. The tribological properties were analyzed using the Chase test as per SAE J661. Worn surface analysis was done using a scanning electron microscope.

Findings
The experimental results indicate that the brake pads filled with premixed dual metal sulfides had good thermal stability, physical, chemical and mechanical properties with stable friction and less wear rate due to better lubrication preventing friction undulations.

Originality/value
This paper explains the influence of premixed dual metal sulfides as a replacement for antimony trisulfide in brake pads formulation to enhance the tribological performance by preventing friction undulations.

Mechanical behaviour and interface evaluation of hybrid MIM/PBF stainless steel components
Authors: Mehmeti Aldi , Penchev Pavel , Lynch Donal , Vincent Denis , Maillol Nathalie , Maurath Johannes , Bajolet Julien , Wimpenny David Ian , Essa Khamis , Dimov Stefan 
Published: October 2020

Purpose
The paper reports an investigation into the mechanical behaviour of hybrid components produced by combining the capabilities of metal injection moulding (MIM) with the laser-based powder bed fusion (PBF) process to produce small series of hybrid components. The research investigates systematically the mechanical properties and the performance of the MIM/PBF interfaces in such hybrid components.

Design/methodology/approach
The MIM process is employed to fabricate relatively lower cost preforms in higher quantities, whereas the PBF technology is deployed to build on them sections that can be personalised, customised or functionalised to meet specific technical requirements.

Findings
The results are discussed, and conclusions are made about the mechanical performance of such hybrid components produced in batches and also about the production efficiency of the investigated hybrid manufacturing (HM) route. The obtained results show that the proposed HM route can produce hybrid MIM/PBF components with consistent mechanical properties and interface performance which comply with the American Society for Testing and Materials (ASTM) standards.

Originality/value
The manufacturing of hybrid components, especially by combining the capabilities of additive manufacturing processes with cost-effective complementary technologies, is designed to be exploited by industry because they can offer flexibility and cost advantages in producing small series of customisable products. The findings of this research will contribute to further develop the state of the art in regards to the manufacturing and optimisation of hybrid components.
Building an OER program based on stakeholder feedback
Authors: Petrich Marisa 
Published: October 2020

PurposeThis study aims to outline a library-led open educational resource (OER) training program for faculty and an assessment of barriers to OER adoption on campus. This study examines program assessment data (including faculty-reported needs to increase the likelihood of OER adoption) and analyzes a community-focused outreach strategy for a new OER program.Design/methodology/approachThis program took a user-centered approach to developing campus support services for OER that specifically sought to address local needs and challenges. It intentionally incorporated strategies related to faculty motivation and satisfaction.FindingsAlthough this faculty incentive program did not require OER adoption, a high number of voluntary OER adoptions occurred and participants showed interest in sharing information about OER across campus. Information about barriers to adoption informed future services.Practical implicationsThis paper presents an adaptable model to launch new OER services and encourage a culture of using affordable course materials.Originality/valueThis project gathered information and identified collaborators to help build a sustainable, community-oriented OER program. The program focused early efforts on collecting and incorporating stakeholder feedback rather than moving directly to strategies focused on adopting or creating OER. It offers a model for other libraries to follow in creating sustainable practices.
Does corporate social responsibility initiative restrain young people from irregular migration in sub-Saharan Africa? Evidence from Nigeria’s oil-producing communities
Authors: Uduji Joseph Ikechukwu , Okolo-Obasi Elda Nduka 
Published: October 2020

Purpose
The purpose of this paper is to critically examine the multinational oil companies’ (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on irregular migration urge of rural youths in the oil-producing communities.

Design/methodology/approach
This paper adopts a survey research technique, aimed at gathering information from a representative sample of the population, as it is essentially cross-sectional, describing and interpreting the current situation. A total of 2,100 households were sampled across the Niger Delta region of Nigeria.

Findings
The results from the use of a combined propensity score matching and logit model indicate that GMoU model has made significant impact in dissuading young people from irregular migration drive.

Practical implications
This implies that if the MOCs increase the CSR intervention on young development initiatives that focus on creation of jobs and provision of financial and other resources that support local entrepreneurs, the push factors that compel youth irregular migration in sub-Saharan Africa would be deterred.

Social implications
The fight against irregular migration of African youths and subsequent demise by sea, deserts and along the Mediterranean route can only succeed if cluster development boards of GMoUs are able to draw on young people to participate fully in the CSR intervention plans and programmes.

Originality/value
This research adds to the literature on multinational enterprises’ CSR initiatives in sub-Saharan Africa and rationale for demands for social projects by host communities. It concludes that business has an obligation to help in solving problems of public concern.
A learner-centric model of learning organizations
Authors: Akella Devi 
Published: October 2020

Purpose
This paper aims to contribute by placing the missing “learner agent” within the entire process of learning. To understand under what social conditions, it is possible to develop autonomous learners who are conscious of self, able to reflect on their identities, roles and responsibilities, to learn and develop professionally, in alignment with the organizational goals and objectives.

Design/methodology/approach
The paper uses empirical data from a higher educational institution to provide insights on how it might be possible to intervene to incorporate workspaces which allow learner agent reflection resulting in individual and organizational learning processes, devoid of power exercises and manipulation strategies.

Findings
The empirical findings reveal the crucial role of learner agents, and positive outcomes associated with learning that happens be an autonomous choice and process, with minimal structural influence. The relevance of reflection, personal identity, social conditions, dialogic third spaces and transformation opportunity structures in developing lifelong learners, learning societies and democratic learning organizations is emphasized.

Research limitations/implications
This study suggests plausible directions in which the model of learning organizations can move forward, in the form of designing transformation structures or workspaces where learner agents have the opportunity to reflect on their tacit knowledge, job responsibilities and functions in an autonomous manner to generate learning, which is democratic and un-contested in nature.

Originality/value
The significance of learner agent in the entire learning process is demonstrated, to place forward a learner-centric model of learning organization where structure and agency harmoniously merge to form one common ground, where individual learning becomes organizational learning with no hidden power dynamics. Empirical evidence is provided to demonstrate how learning can be a win–win situation for all organizational groups.
