Abstract

Purpose

This paper aims to investigate the importance of auditing for election privacy via issues that appear in the state-of-the-art implementations of e-voting systems that apply threshold public key encryption (TPKE) in the client such as Helios and use a bulletin board (BB).

Design/methodology/approach

Argumentation builds upon a formal description of a typical TPKE-based e-voting system where the election authority (EA) is the central node in a star network topology. The paper points out the weaknesses of the said topology with respect to privacy and analyzes how these weaknesses affect the security of several instances of TPKE-based e-voting systems. Overall, it studies the importance of auditing from a privacy aspect.

Findings

The paper shows that without public key infrastructure (PKI) support or – more generally – authenticated BB “append” operations, TPKE-based e-voting systems are vulnerable to attacks where the malicious EA can act as a man-in-the-middle between the election trustees and the voters; hence, it can learn how the voters have voted. As a countermeasure for such attacks, this work suggests compulsory trustee auditing. Furthermore, it analyzes how lack of cryptographic proof verification affects the level of privacy that can be provably guaranteed in a typical TPKE e-voting system.

Originality/value

As opposed to the extensively studied importance of auditing to ensure election integrity, the necessity of auditing to protect privacy in an e-voting system has been mostly overlooked. This paper reveals design weaknesses present in noticeable TPKE-based e-voting systems that can lead to a total breach of voters’ privacy and shows how auditing can be applied for providing strong provable privacy guarantees.

Abstract

THE BODLEIAN LIBRARY at the beginning of the eighteenth century is described in some detail in the diary kept by Zacharias Conrad von Uffenbach during his visit to England in 1710, when he was accompanied by his younger brother Johann Friedrich. Though the diary is, in M. R. James's phrase, full of ‘girdings and sniffings’, it also contains keen observations and intelligent criticisms, and the remarks are those of a scholar.

Abstract

Kerala is considered to be the must-see locations in a life time of a tourist. Tourism has become an important vital cog in the economy of the state of Kerala. The state boasts of an excellent road and rail networks, lakes and natural canals and the backwaters. The study was done in the back water destinations – Alappuzha, Kollam, Kottayam and Kuttanad. The study was carried out to learn about the relationship between the brand name of the backwater tour operator, the offers they give and the selection of backwater destination post-COVID-19. This descriptive study was conducted through a survey method. The study used qualitative approach by using a questionnaire and the total sample composed of 400 respondents. Analysis was done with the help of chi-square. The researcher found that there exists a significant relation between offers in tour package and backwater destination, but there is no significant relation existing between brand name and selection of a backwater destination.

Abstract

Purpose

Although previous studies noted the importance for organizations in establishing an innovation strategy, few have examined innovation orientation as a multidimensional knowledge configuration. Therefore, this study draws on the valuable theoretical underpinnings of the resource-based view and information processing theory to examine the mechanism through which an organization's innovation orientation (IO) and team unlearning (TU) can impact new product development (NPD) success.

Design/methodology/approach

A causal model was developed in order to analyze the role of innovation orientation and team unlearning on NPD success. This proposed model and several hypotheses were gauged using data from 255 NPD team members from Taiwanese high-tech and traditional companies.

Findings

The results indicate that both IO and TU relate to outcomes. Specifically, this study demonstrates that it is insufficient that firms simply establish the configurations needed to enhance their IO and TU, firms also need to find out the correct mechanism to enhance NPD success. The relationships between IO, TU and NPD success were fully mediated by team information processing.

Originality/value

This report sheds light on the importance of innovation orientation and team unlearning in today's NPD process and uncovers the underlying mechanism through which IO and TU contribute to NPD success. It also offers precise advice for the assessment of management of team information-processing to boost the performance of new products.

Abstract

Purpose

The purpose of this paper is to compare the governance structures of two distinctive governance forms: the family firm and the leveraged buyout (LBO). The paper also explores the relative performance of these two organizational forms over the course of the economic business cycle.

Design/methodology/approach

The paper provides a theoretical treatment of the family firm and the LBO using the stewardship perspective and agency theory. The analysis anticipates the board structure for each organizational form and relates family firm and LBO governance to performance over the business cycle.

Findings

From a conceptual treatment, the family‐owned concern exhibits board characteristics reflecting the longer‐term orientation of the firm, with boards empowered to include non‐economic, as well as economic, goals. LBOs are structured to maximize shareholder value over a shorter time horizon. LBOs may take advantage of expansionary environments whereas family firms may be better prepared for economic down‐cycles.

Research limitations/implications

The paper takes a holistic approach to contrasting two organizational forms that fit their respective theoretical frames and compares some of their more salient governance characteristics and performance over the business cycle.

Practical implications

Managers and boards can structure governance to manage the business cycle. Stakeholders can selectively engage firms that portray vital governance characteristics for their benefit and may also pressure boards and top management to make necessary governance improvements.

Originality/value

The paper offers an introductory comparison between family firms and LBOs in terms of governance and managing the firm over the business cycle. This paper makes the case that some organizational forms are better suited to certain types of economic climates.
