Abstract

Capacity development in fragile environments in Africa has often proven to be a complex undertaking. This has largely been because of existing knowledge gaps on what exactly causes fragility of states, the economy and society. The liberal peace development model that generally informs post‐conflict reconstruction and capacity development has a limited conception of fragility by narrowly focusing on the national dimensions of the problem, promoting donor‐driven solutions, emphasizing minimal participation of beneficiary actors in the identification and prioritization of capacity development needs, and by subcontracting the design and management of projects and programs. The resulting capacity development impact has generally been disappointing. In the absence of homegrown strategic plans, stakeholder participation and ownership, international development partners have all too often addressed capacity gaps by financing training, supply of equipment and professional exchanges of parliamentarians and parliamentary staffers. These efforts usually achieved their presumed number targets but tended to ignore addressing the larger issues of political economy within which capacity development take place. However, the recent re‐conceptualization of parliamentary capacity development as a development of nationally owned, coordinated, harmonized, and aligned development activities seems to be gaining growing attention in Africa. As the experience of Rwanda eloquently demonstrates, capacity development is essentially about politics, economics and power, institutions and incentives, habits and attitudes – factors that are only partly susceptible to technical fixes and quantitative specifications. These structural factors have to be negotiated carefully and tactfully.

Abstract

Presents two models. Model I deals with some characteristics of a single unit system with a sensing device and two types of repairmen. The unit is attached to a sensing device which completely monitors the operating or non‐operating status of the unit. The regular repairman is always available with the system and inspects the operation of the sensing device. If the device is not working, then an expert repairman is called to the system and the operational status of the unit is now monitored by the expert repairman. It is assumed that the failure of the unit, repair of the regular, expert and the status of the sensing device are stochastically independent random variables each having an arbitrary distribution. Several important results have been derived including profit with some applications. In model II, a two‐unit cold standby system with pre‐inspection is considered. In this model, first the regular repairman inspects every unit that fails to ascertain whether he is able to repair it or not. If he can repair it, he proceeds; otherwise an expert repairman is called. An analytical approach to find the optimum interchanging time of units by giving rest to the operative unit is obtained.

Abstract

Roots of global Terrorism are in ‘failed’ states carved out of multiracial empires after World Wars I and II in name of ‘national self‐determination’. Both sides in the Cold War competed to exploit the process of disintegration with armed and covert interventions. In effect, they were colluding at the expense of the ‘liberated’ peoples. The ‘Vietnam Trauma’ prevented effective action against the resulting terrorist buildup and blowback until 9/11. As those vultures come home to roost, the war broadens to en vision overdue but coercive reforms to the postwar system of nation states, first in the Middle East. Mirages of Vietnam blur the vision; can the sole Superpower finish the job before fiscal and/or imperial overstretch implode it?

Abstract

Purpose

This paper aims to examine the characteristics of banks that were the target of intervention in the form of bailout or failure during the financial crisis and, of those subjected to intervention, what characteristics distinguish those that received bailout funds from those that were deemed failures.

Design/methodology/approach

The study estimates a series of logit regressions in an effort to identify the causes of regulatory intervention while controlling for bank-level characteristics and the economic and regulatory environment.

Findings

The empirical results indicate that many of the same characteristics associated with banks receiving bailout funds are similar to the characteristics associated with failed banks. However, non-performing loans increased the likelihood of failure, but reduced the likelihood of a bank receiving Capital Purchase Program (CPP) funds, suggesting that regulatory authorities discriminated in their use of CPP funds based on the quality of a bank’s asset portfolio. Further, those banks located in states with limits on de novo branching and those banks that are part of a multi-bank holding company structure were less likely to fail but were more likely to receive CPP funds.

Originality/value

This paper provides a comprehensive analysis of regulatory intervention in the banking industry during the late 2000s financial crisis and the impact of different banking organizational structures, economic circumstances, and financial fragility on the likelihood of a bank failing or receiving bailout funds.

The purpose of this paper is to study repairable consecutive‐k‐out‐of‐n: systems with r repairmen and a sensing device.

Abstract

Purpose

The purpose of this paper is to study repairable consecutive‐k‐out‐of‐n: systems with r repairmen and a sensing device.

Design/methodology/approach

The system can either be a circular C(k, n: G) system or a linear C(k, n: G) system. The working time and the repair time of each component in the system and the sensor detection time are exponentially distributed. Every component after repair is perfect. Each component is classified as either a key component, or an ordinary one according to its priority role to system's repair. A sensing device is introduced to detect the failure of each component in the system in advance and completion of repair of components. If the repair is completed, the sensor will send the component to standby according to its priority. The state transition probabilities of the system are derived using the definition of generalized transition probability. To obtain the reliability and availability Laplace transform techniques have been used.

Findings

The Kolmogorov‐Feller forward equations are derived for both linear and circular systems. Reliability and MTTF of both the systems are derived using Laplace transforms. Numerical examples are given in detail to demonstrate the theoretical results and these verify the validity of the studied system.

Research limitations/implications

A consecutive‐k‐out‐of‐n system consists of a sequence of n‐ordered components along a line or a circle such that the system is good if and only if at least k consecutive components in the system are good. Each component in the system is classified as key component or ordinary component according to its priority in system functioning. By using a sensing device the failure can be detected in advance.

Originality/value

This study indicates that by using a sensing device we can detect the failure in advance. Thus, the reliability and MTTF of the system can be improved.

Abstract

Purpose

The purpose of this paper is to study the combined effect of human error, common‐cause failure, redundancy, and maintenance policies on the performance of a system composed of three‐state devices.

Design/methodology/approach

Generalized expressions for time‐dependent and steady state availability of a generalized maintainable three‐state device parallel system subjected to human errors and common‐cause failures are developed in the paper under two maintenance policies: Type I repair policy (i.e. only the completely failed system is repaired); and Type II repair policy (i.e. both partially and completely failed system is repaired). The Markov method is used to develop general and special case expressions for state probabilities, and system time‐dependent and steady state availabilities.

Findings

In the case of three‐state devices, it is demonstrated that by increasing the number of redundant devices in parallel do not necessarily lead to the improvement in the system availability. In fact, the availability of the system depends significantly on the dominant failure mode of the devices (i.e. short‐mode or open‐mode). When comparing the effect of maintenance policies on the system availability, it is observed that the Type II repair policy does not lead to an improvement in the system availability. Furthermore, it is observed that both human error and common‐cause failure independently lead to lower system availability.

Practical implications

This study will help maintenance engineers and reliability practitioners to become aware of the combined impact of redundancy, human error, common‐cause failure, and maintenance policies on the performance of the three‐state device systems. Consequently, they will make better maintenance related decisions in organizations such as oil refineries and power stations that use three state devices quite extensively.

Originality/value

Most of the past models have independently studied the effects of redundancy, human error, and common‐cause failure on maintainable system made up of three‐state devices. This effort is one of the first attempts to study the combined effects of all these factors in a parallel system composed of three state devices.

Findings

Reliability measures have been computed for different types of configuration. It generalized the results for purely series and purely parallel configurations.

Research limitations/implications

This research may be beneficial for industrial system performances whereas a k-out-of-n-type configuration exists.

Practical implications

Not sure as it is a theoretical assessment.

Social implications

This research may not have social implications.

Originality/value

This work is the sole work of authors that have not been communicated to any other journal before.

Abstract

Purpose

The purpose of this study is to develop Markovian model to obtain the transient probabilities to determine mean-time-to-failure and reliability function and further steady state availability of the repairable system. As the system parameters are uncontrollable factors; thus the life times, repair times and recovery/reboot time are assumed to be as uncertain or fuzzified distributions.

Design/methodology/approach

The fuzzy approach is introduced to investigate the reliability measures of load sharing repairable system which consists of two operating units and one standby unit. On the failure of an operating component, it is instantly spotted, located and sent for recovery procedures with coverage probability. In case of imperfect recovery, reboot takes place.

Findings

On the basis of extension principle and mathematical programming approach, the authors establish membership functions for system characteristics with the help of α-cuts. To demonstrate the practical validity of the proposed fuzzified model, numerical illustrations are performed.

Originality/value

The model proposed for reliability analysis may cheer up the continuance of the work towards more applications in repairable systems. Therefore, the reader is provided with useful intuition into the nature of fuzzy computations and practical amendments while measuring ambiguous data.

Abstract

Purpose

Drawing on variables cited in the turnaround literature, this study aims to explore whether information contained within annual reports is useful in distinguishing between distressed companies that enact a turnaround and those that fail.

Design/methodology/approach

This study develops a discriminant model to identify distressed companies that have turnaround potential.

Findings

Analysis of the results reveals that successful turnarounds are associated with the severity of the distressed state, its determinants, with the extent of change in the distressed state since the previous year, and firm size.

Originality/value

This article is of use in identifying what information is useful in annual reports.

Abstract

Purpose

The purpose of this paper is to deliberate the system reliability of a system in combination of three subsystems in a series configuration in which all three subsystems function under a k-out-of-n: G operational scheme. Based on computed results, it has been demonstrated that copula repair is better than general repair for system better performance. The supplementary variable approach with implications of copula distribution has been employed for assessing the system performance.

Design/methodology/approach

Probabilistic assessment of complex system consisting three subsystems, multi-failure threats and copula repair approach is used in this study. Abbas Jubrin Bin, V.V. Singh, D.K. Rawal, in this research paper, have analyzed a system consisting of three subsystems in a series configuration in which all three subsystems function under a k-out-of-n: G operational scheme. The supplementary variable approach with implications of copula distribution has been employed for assessing the system performance. Based on computed results, it has been demonstrated that copula repair is better than general repair for system better performance.

Findings

In this analysis, four different cases of availability are analysed for Gumbel–Hougaard family copula and also four cases for general repair with similar failure rates are studied. The authors found that when failure rates increase, the system availability decreases, and when the system follows copula repair distribution, the system availability is better than general repair.

Research limitations/implications

This research may be implemented in various industrial systems where the subsystems are configured under k-out-of-n: G working policy. It is also advisable that copula repair is highly recommended for best performances from the system. On the basis of mean time to system failure (MTSF) computations, the failure rate which affects system failure more needs to be controlled by monitoring, servicing and replacing stratagem.

Practical implications

This research work has great implications in various industrial systems like power plant systems, nuclear power plant, electricity distributions system, etc. where the k-out-of-n-type of system operation scheme is validated for system operations with the multi-repair.

Originality/value

This work is a new work by authors. In the previously available technical analysis of the system, the researchers have analyzed the repairable system either supplementary variable approach, supplementary variable and system which have two subsystems in a series configuration. This research work analyzed a system with three subsystems with a multi-repair approach and supplementary variables.
