Abstract
Purpose
Stretch fabrics are employed to create compression in garments for medical, sports, and fitness applications. Although potential correlations between wearing compression garments and physiological or performance metrics have been studied, such correlations require knowledge of the actual compression caused by garments. The purpose of this paper is to demonstrate, compare, and contrast different methods for measuring compression delivered by an exemplar compression garment.
Design/methodology/approach
The exemplar compression garment is a plain jersey knit maternity band. The compression delivered by this garment was determined via three different methods – Tekscan pressure mapping system, Hohenstein Measurement System (HOSY), and a fabric-based analytical model employing uniaxial fabric tensile data.
Findings
HOSY and the fabric-based model, assuming a circular cross section for the garment, provided comparable results for compression versus garment height. However, these methods did not capture the varying compression delivered at different transverse locations when the subject was noncircular in cross section. Assuming an elliptical cross section, the fabric-based model predicted results that were comparable to those measured by the Tekscan system: for example, compressions were approximately 130-160 percent greater at the hip, and approximately 60-100 percent lower at the posterior, than HOSY revealed. Further, the Tekscan system allows the effect of movement on compression to be captured.
Originality/value
This paper compares and contrasts three compression measurement methods and demonstrates the importance of angular position and height dependencies. Further, the fabric-based model is presented as a tool to assist design of compression garments.

Abstract
We develop a Bayesian approach for modeling brain activation and connectivity from functional magnetic resonance image (fMRI) data. Our approach simultaneously estimates local hemodynamic response functions (HRFs) and activation parameters, as well as global effective and functional connectivity parameters. Existing methods assume identical HRFs across brain regions, which may lead to erroneous conclusions in inferring activation and connectivity patterns. Our approach addresses this limitation by estimating region-specific HRFs. Additionally, it enables neuroscientists to compare effective connectivity networks for different experimental conditions. Furthermore, the use of spike and slab priors on the connectivity parameters allows us to directly select significant effective connectivities in a given network.
We include a simulation study that demonstrates that, compared to the standard generalized linear model (GLM) approach, our model generally has higher power and lower type I error and bias than the GLM approach, and it also has the ability to capture condition-specific connectivities. We applied our approach to a dataset from a stroke study and found different effective connectivity patterns for task and rest conditions in certain brain regions of interest (ROIs).

Abstract
Finding answers to questions raised in a given debate presents scholars with the opportunity to not only provide a firmer path toward a resolution to the debate at hand, but also the opportunity to employ somewhat atypical methodological approaches. Specifically, when investigating different facets of a given debate, the opportunity presents itself to (1) employ competing hypotheses, (2) integrate theoretical frameworks, and (3) identify boundary conditions.

Abstract
The Library Association of Ireland issued last month the first number of An Leabharlann, their new official journal. The title, for those of us who do not speak the language of Erin, means The Library. It is an extremely interesting venture which will be followed by librarians on the mainland with sympathetic curiosity. In particular our readers would be interested in the first of a series of articles by Father Stephen J. Brown, S.J., on Book Selection. The worthy Father lectures on this subject at University College, Dublin, in the Library School. It is mainly concerned with what should not be selected, and deals in vigorous fashion with the menace of much of current published stuff. No doubt Father Brown will follow with something more constructive. Mr. T. E. Gay, Chairman of the Association, discusses the need for a survey of Irish libraries and their resources. We agree that it is necessary. The Net Books Agreement, the Council, Notes from the Provinces, and an article in Erse—which we honestly believe that most of our Irish friends can read—and an excellent broadcast talk on the Library and the Student by Miss Christina Keogh, the accomplished Librarian of the Irish Central Library, make up a quite attractive first number. A list of broadcast talks given by members of the Association is included.

Abstract
Purpose
Weber emphasized the informal structure, followers' power, and time in charismatic leadership; yet the extant literature either overlooks or underplays the significance of each of these facets. The aim of this paper is to revisit Weber's conceptualizations of charisma and illuminate these facets, thus creating new avenues for the contemporary charismatic leadership research.
Design/methodology/approach
The focus of this research is on analysis of Weber's conceptualization of charisma. The analysis of selected quotes is grounded within contemporary discourse in order to illustrate how three overlooked facets may propel future research on charismatic leadership.
Findings
By revisiting Weber's seminal work, the paper illustrates several historical findings and identifies research opportunities that are yet to be addressed by contemporary study in charismatic leadership. In doing so, the paper generates a set of propositions as an impetus for future exploration.
Research limitations/implications
To address the three proposed questions, researchers should focus their attention on the exploration of charisma outside of the formal bureaucracy, the dynamic power relations between leaders and followers, and the temporally bound nature of charisma. Given the nature of these questions, researchers may also consider alternative research methods such as in-depth case studies and narratives in order to more fully capture the dynamic and unpredictable nature of charisma in complex contexts.
Originality/value
Contemporary research largely overlooks or underplays the issues of time, the informal structure, and followers in the study of charisma. Through analysis of Weber's writings, this paper brings to the forefront these issues, and thus provide rich opportunities for future research on charismatic leadership.

Abstract
Purpose
The purpose of this study is to examine the effect of the religiosity of the chief executive officer (CEO) on Indonesian banks’ performance.
Design/methodology/approach
The research method used was a review of the annual reports of banking companies in Indonesia from 2015 to 2019 and a web-based search to determine the religiosity of the CEOs. This study comprised 88 banking companies in Indonesia that come under the supervision of the Financial Services Authority.
Findings
The results of this study show that banks led by religious CEOs had better financial performance, as measured by their ROA and ROE, than those led by not very spiritual CEOs. These results indicate the importance of religiosity in organizations, especially at the top management level, for achieving better bank performance.
Practical implications
This research results show that religiosity plays an essential role in the banking business sector. This research adds to the literature on CEOs’ characteristics based on their religiosity and the concomitant effect on banking performance.
Originality/value
This study shows how individual religious beliefs influence the corporate behavior of top management, particularly the CEOs, and why this is crucial for organizational decision-making. This study measures an individual's religiosity (i.e. a CEO) based on that individual's actions in their workplace environment.

Abstract
Faith-based nonprofit organizations often do not track the transformational outcomes of programs because these outcomes are considered intangible and difficult to quantify. Bible League International’s (BLI) Board of Directors commissioned the development of an instrument to assess the transformative impact of BLI’s programs. This was accomplished in collaboration with the Metadigm Group. From field interviews and from relevant literature, three measurement domains emerged: Program Participant Outcomes, Worker Capacity and Affiliation, and Program Function. In pilot tests, qualitative methods were used to refine the instrument. Due to time and budgetary restraints, the project ended prior to conducting reliability studies. This case study presents factors driving faithbased nonprofits to measure transformational outcomes, exposes some of the methodological challenges in accessing transformational outcomes, and provides an approach to developing an instrument to quantify transformational outcomes

Abstract
Purpose
The financial crisis has been something of a turning point in the regulatory response to financial crime around the world. The failure of light‐handed regulation and risk assessment by both industry and regulators made the operation of financial regulatory agencies almost untenable, often leading to calls for their replacement by more effective agencies. The purpose of this paper is to assess the nature of this regulatory challenge.
Design/methodology/approach
The paper discusses some of the case studies that have emerged from the dark side of regulatory and enforcement policies in recent times.
Findings
A culture of minimal regulation of financial markets meant that many undesirable practices (such as insider trading, foreign corrupt practices, tax avoidance, money laundering and other frauds) were able to avoid detection until public outrage led to regulatory and prosecutorial agencies being prompted into action following the collapse of financial markets.
Research limitations/implications
More detailed studies of particular institutions will be necessary; this will become possible as the current financial crisis subsides.
Originality/value
This paper explores some of the factors behind this state of affairs and makes policy recommendation in regard to the need for more effective internal controls and monitoring measures within the modern financial corporation.

Abstract
Purpose
This study aims to explore the relationship between risk governance characteristics (chief risk officer [CRO], chief financial officer [CFO] and senior directors [SENIOR]) and regulatory adjustments (RAs) in Organization for Economic Cooperation and Development public commercial banks.
Design/methodology/approach
Using principal component analysis (PCA) and regression models, the research analyzes a representative data set of these banks.
Findings
A significant negative correlation between risk governance characteristics and RAs is found. Sensitivity analysis on the regulatory Tier 1 capital ratio and the total capital ratio indicates mixed outcomes, suggesting a complex relationship that warrants further exploration.
Research limitations/implications
The study’s limited sample size calls for further research to confirm findings and explore risk governance’s impact on banks’ capital structures.
Practical implications
Enhanced risk governance could reduce RAs, influencing banking policy.
Social implications
The study advocates for improved banking regulatory practices, potentially increasing sector stability and public trust.
Originality/value
This study contributes to understanding risk governance’s role in regulatory compliance, offering insights for policymaking in banking.
