This paper aims to study the design and characterization of a 3D printed tetrakaidecahedron cell-based acoustic metamaterial. At present, the mitigation of low-frequency noise involves the utilization of spatially demanding materials for the absorption of sound. These materials lack the ability for targeted frequency control adjustments. Hence, there is a requirement for an approach that can effectively manage low-frequency noise using lightweight and durable materials.

The CAD model was created in SolidWorks and was manufactured using the Digital Light Processing (DLP) 3D printing technique. Experimental study and numerical simulations examined the metamaterial’s acoustic absorption. An impedance tube with two microphones was used to determine the absorption coefficient of the metamaterial. The simulations were run in a thermoviscous module.

The testing of acoustic samples highlighted the effects of geometric parameters on acoustic performance. Increment of the strut length by 0.4 mm led to a shift in response to a lower frequency by 500 Hz. Peak absorption rose from 0.461 to 0.690 as the strut diameter was increased from 0.6 to 1.0 mm. Increasing the number of cells from 8 to 20 increased the absorption coefficient and lowered the response frequency.

DLP 3D printing technique was used to successfully manufacture tetrakaidecahedron-based acoustic metamaterial samples. A novel study on the effects of geometric parameters of tetrakaidecahedron cell-based acoustic metamaterial on the acoustic absorption coefficient was conducted, which seemed to be missing in the literature.

The essence of responsibility in leadership can help to integrate course of action of policy makers and Corporate Social Responsibility (CSR). This will augment meaningfulness of the humanity in human in the present era of isolationism, when everyone is becoming the part of the race. However, the precise criterion of different contexts of behaviour for Corporate Social Performance (CSP) that the pioneers or leaders understood and demonstrate the accountability is uncertain. This ambiguity and multiple dimensions of responsible leadership (RL) present in the current literature are concurring. Gaps identified indicates that there should be a methodical research on the impact of such leadership on the societal and firm level of outcomes. By following interpretivism approach in research, this paper relies on the content analysis of speeches, welcome stories, biographies and recorded interviews of selected business leaders and entrepreneurs in India. This research study identifies four different dimensions of orientation that leaders practice while fulfilling their responsibility and envisioning CSR. The limitation of this study is that it tries to map the leader's orientation under a cultural spectrum, but its findings still provide major insights for the future perspective of research based on the RL matrix model. The outcome of this study will be useful for the leaders to recognise the dimensions of responsible leadership for creating value addition in their style and practices. The model identified envisages practical implications of the corporate social responsibility theory.

Notes how rapid urbanization is transforming the developing world – creating cities, which on the one hand offer opportunities for global economic activity, but on the other hand are beset with serious local civic, economic and social problems. New networks based on information and communication technologies are increasingly being woven into the fabric of these cities supporting the connectedness of powerful groups both within the city and between cities around the world. These flows of global information and communication between powerful groups in the city involved in global economic activity coexist with intense face‐to‐face interactions at the local level. Bangalore in South India presents a major case study of this global/local interaction, being a focal point for software development in the Asian region and globally, but also beset with local problems of civic deficiencies, growing poverty and income inequality. Explores some of the issues which arise as Bangalore serves as a nexus that links global and local networks of exchange. Examines two Bangalore networks which typify global and local duality: the network of software firms located in high technology enclaves in and around the city, and the ostracised network of the slum dwellers of Bangalore, gradually being brought into mainstream discussions of governance in the city. Finds considerable similarities between global networks and local networks and outlines some of these dynamics.

The banking sector requires a major comeback with the series of bank frauds that has shook the nation. The rising non-performing assets (NPAs) and corporate frauds find their roots in the top-level management or executive levels. The purpose of this study to analyse the behavioural component with corporate governance lapses for creating a trail and to what extent it can contribute to forensic analysis to help reduce and prevent fraud in the future.

This study is investigative in nature. This study uses case study approach by taking into account the major Advance–NPA–Fraud cases over period of 2010–2022. RBI data for bank advances, NPAs and advances-relate frauds from 2005 to 2019 were studies and interpreted for creating a trend and pattern for the reduction and prevention of frauds.

The authors found that behavioural factors and personalities affect the systems and culture of the company, thereby giving a jolt to the corporate governance mechanisms along with various entities like depositors, consumers and shareholders.

Assessing the behavioural aspects for risk mitigation remains unexplored in the banking sector. The personality dimension can help in contributing to comprehending the mental aspects and the reasons behind the combination of dark triads with economic offences.

This study is beneficial to all the beneficiaries of the banking sector and the economy at large in understanding the implications of risks because of patterns formed by emotions and vulnerability towards economic and fugitive economic crimes.
