Eutectic Sn‐Ag solder is being considered as a potential replacement for Sn‐Pb solders. A potential drawback to using the eutectic Sn‐Ag solder is its higher melting point, 221°C, compared with the eutectic Pb‐Sn solder. Owing to its higher melting temperature, the eutectic Sn‐Ag solder is also being considered for automotive under‐the‐hood applications, which experience high temperature environments. Electronic components and/or circuit boards are often coated with Pb‐bearing solder to facilitate soldering operations. Soldering Pb‐bearing solder coated components and/or boards with eutectic Sn‐Ag solder will result in joints contaminated with Pb. In this study, the effects of Pb contamination on eutectic Sn‐Ag solder joints were investigated using three ternary alloys made by incorporating some Pb into eutectic Sn‐Ag solder. These ternary alloys all showed a peak at 178°C in heating curves obtained using Differential Scanning Calorimetry (DSC), which resulted from the ternary eutectic composition in the Sn‐Ag‐Pb system. The Pb phases in the ternary alloys were found to be dispersed throughout the microstructure. A practical implication of Pb contamination in eutectic Sn‐Ag solder joints is that the service temperature of such joints would be limited by the lower melting temperature of the ternary eutectic phase.

This paper extends previous research by reexamining the difference in cross‐sectional variability of Japanese and U.S. price‐to‐earnings (PE) ratios. A simple model is developed to decompose the variance of the PE ratio into three components: the variance of the price‐to‐book (PB) ratio, the variance of the book‐to‐earnings (BE) ratio and the covariance of the PB and BE ratios. We analyze the behavior of the cross‐sectional variability of the PE ratio and its components and compare the behavior of these ratios across the U.S. and Japanese markets. We find that the cross‐sectional variability of the PE ratio in the Japanese market is consistently lower than that of the PB ratio and the converse is true for the U.S. market. The cross‐sectional variability of PE ratios in Japan is lower than that in the U.S. and the converse is true for the PB ratio. Our results are inconsistent with those reported by Bildersee et al. and indicate that the main factor causing the differences between the cross‐sectional variability of PE ratios and PB ratios is the high negative covariance of the PB and BE ratios.

The defective coin problem involves the identification of a defective coin, if any, and ascertaining the nature of the defect (heavier/lighter) from a set of coins containing at the most one defective coin, using an equal‐arm‐pan‐balance. An algorithmic analysis of the problem is considered. The solution strategy to minimise the number of weighings required to detect the defective coin is based on a problem reduction approach involving successive decomposition of the problem into subproblems until it is trivially solved. The algorithm is capable of generating all possible optimal solutions.

Purpose – The purpose of this research is to investigate the relationship of lead (Pb) and zinc (Zn) contents in sediment of Faunus ater (F. ater) population density and to analyze the relationship between Pb and Zn accumulation in F. ater with F. ater density in Reuleng River, Leupung, Aceh Besar.

Design/Methodology/Approach – Sampling was conducted in November 2016 until January 2017. Density of F. ater was analyzed by density formula while its relationship to Pb and Zn in sediments and F. ater was conducted by correlation analysis method.

Findings – The results showed that correlation between Pb and Zn in sediments and in F. ater varies at each locations on every month of sampling. Pb and Zn content in sediments found a fluctuating relationship in each month of sampling with density of F. ater. Correlation of Pb content in sediments with F. ater density showed a medium correlation in January 2017 with r-value = 0.665. Zn in sediment has a very strong correlation to F. ater density in November 2016 with r-value = 0.891. Pb in F. ater has a medium correlation to F. ater density in January 2017 with r-value = 0.436. Furthermore, accumulation of Zn in F. ater to its density does show some apparent correlation in each month of sampling.

Research Limitation/Implications – This research gives information about the relationship of Pb and Zn contents in sediment to density of F. ater and to analyze correlation of Pb and Zn in F. ater to density of F. ater in Reuleng River, Leupung, Aceh Besar district.

Originality/Value – This is the first time research is conducted about on the correlation between lead and zinc to obtain the density of F. ater.

Sustainability is a pressing challenge of governance and public financial management. One key element of sustainable governance is the role of citizens. Participatory budgeting (PB) is a participatory tool with which citizens can influence public administration. PB is a democratic process that grants people real power over real money and it has spread around the world. This special issue explores the role of PB in the context of sustainable governance. In this editorial, the authors aim to approach PB as a form of sustainable governance.

In this editorial, the authors collaborate in the analysis of how PB is implicated in the public management of complex social, economic and ecological issues. The authors identify key dimensions of internal and external sustainability based on prior research. The authors approach these dimensions as an internal–external nexus of sustainable governance in which organizational and financial sustainability are the internal dimensions and socio-political and environmental sustainability are the external dimensions.

Even though PB can be seen as one tool for citizen participation, it has the potential to foster sustainability in multiple ways. PB, as a form of sustainable governance, requires a financially and administratively sustainable organizational process that results in the institutionalization of PB. It also includes thorough consideration of socio-political and environmental sustainability impacts of PB.

Academics are actively studying PB from various perspectives. However, most of this work has approached PB from the viewpoints of design and results of PB, and less is known about its institutional settings. PB has not yet been adequately studied in the context of sustainability, and there is a need to scrutinize PB as a form of sustainable governance.

This paper aims to study the interplay between a risk-averse national brand manufacturer's (NBM) selling mode decision and a risk-neutral e-platform's private brand (PB) introduction decision.

A game theory model is used to solve selling mode decision, that is whether transform the selling mode from the wholesale mode to the marketplace mode, and PB introduction decision, that is, whether introduce the PB.

The results show that for the NBM, under certain condition, the NBM's selling mode decision is not affected by the e-platform's PB introduction decision. High revenue-sharing rate is conducive only when the difference in consumer preference between the PB and the national brand (NB) is small. The NBM's risk aversion will improve the applicability of the marketplace mode. For the e-platform, high PB preference of consumers and risk-averse behavior of the NBM is not conducive to PB introduction. For the supply chain, scenarios that the NB monopolizes the market under the wholesale mode and PB introduction under the marketplace mode should be prevented. PB introduction under the wholesale mode will become the only equilibrium with the increase of risk aversion of the NBM. Finally, the authors extend the scenario that consumers prefer the PB and the e-platform is risk-averse enterprise and find that PB introduction under the wholesale mode is detrimental to the NBM but beneficial to the supply chain. The impact of consumers' PB preference on the e-platform's PB introduction is opposite to the basic model. The impact of the e-platform's risk aversion on game equilibrium is opposite to that of the NBM's risk aversion.

This paper is first to study selling mode decision and PB introduction decision when considering enterprises' risk-averse attitude.

With the advent of the second wave of COVID-19 pandemic, there is a need to analyse the scenario of panic buying (PB) behaviour of the customers which was evident in the first wave. This paper aims to examine the PB scenario as well as the moderating effect of past buying experience (PBE) on PB in the second wave of the COVID-19 pandemic.

This study is based on the theories of stimulus–organism–response model and the competitive arousal model. Based on these theories, this paper investigates how panic situation created by external stimuli such as perceived scarcity (PS), perceived risk (PR), news in media (NM) and social learning affect the perceived arousal (PA) among people which in turn influence the PB behaviour of customers. Data were collected from 253 customers from different parts of India. Structural equation modelling is used to analyse the moderating effect of PBE on the PB in the second wave of COVID-19 pandemic.

The results indicate that the PS, PR and NM continue to be strong predictors of a buyer for PA. However, the PB is not reinforced by the moderation effect of PBE.

This paper investigates the consumers’ PB behaviours in the wake of third wave of COVID-19 pandemic which add to the existing literature of COVID-19 pandemic. Moreover, this study also examines how previous buying experience can moderate the PB behaviour of the customers in subsequent phases of COVID-19 pandemic. This supports the potential effectiveness of self-regulation as an intervention strategy for reducing PB behaviours during the COVID-19 pandemic.

This study emphasises the impact of external stimuli like PS, PR and media coverage on PB behaviour, marketers and policymakers should manage to avoid triggers. Although PBE may not moderate PB during a pandemic, it can play a significant role in future buying behaviour. Anticipating potential triggers and designing effective marketing strategies that cater to customers' needs can help manage PB behaviour during disasters or pandemics. In addition, promoting conscious consumption awareness and self-regulation practices among customers can help manage PB behaviour, benefit the environment and society and make customers more responsible buyers.

To the best of the authors’ knowledge, this study examines the PB behaviour of customers during the second wave of COVID-19 pandemic for the first time. This study also investigates the moderating effect of PBE on the PB behaviour of customers during a pandemic which is new and significant that extends the literature on PB behaviour during a pandemic.

This research aims to examine the introduction of participatory budgeting (PB) in local governments in two Francophone countries, namely, Benin and Niger, and how local contextual factors influence its practices.

The research employs a multiple case study design with a comparative approach to analyze the introduction and practices of participatory budgeting across selected municipalities in Benin and Niger. Hopper (2017) and Lassou et al.’s (2018) notion of “pragmatism” within neopatrimonialism is mobilized to analyze the data from sources including interviews and documents. The analysis is conducted at both the country and local government levels.

Participatory budgeting took roots in a number of municipalities. Its introduction and adoption has promoted participatory governance especially from traditionally marginalized segments of society (e.g. women); albeit to varying degrees, in the face of the prevailing national neopatrimonial context. Furthermore, despite donor's push for a standardized model of PB implementation, actual practices took varying shapes, a consequence of differing local conditions and circumstances.

In terms of limitation, it was not possible to access a number of research participants sought, particularly in Niger. But access to key documents from government, donors and civil society organizations help mitigate this to a large extent.

A major practical implication is the importance of adaptation to local socio-economic contexts and circumstances. As shown in the study, a blanket introduction and implementation of PB across societies based on a standardized model is unlikely to succeed and be sustained in the long run. A great deal of flexibility is required to accommodate indigenous realities on the grounds.

The study contributes to shed light on public sector budgeting regarding participatory budgeting practices in an under-researched setting: Francophone Africa.

The purpose of this research is to identify and test selected economic and organisational factors influencing the sustainability of participatory budgeting (PB) in Slovakia.

The data were collected from websites and publicly available documents from all local governments with urban municipality status in Slovakia, for a total of 155 municipalities, 59 of which have established a participatory budget. The main method applied was correlation analysis.

The findings indicate: (1) a weak inverse correlation between debt level and the continuous existence of PB in municipalities; (2) a moderate direct correlation between the duration of PB in a municipality and integration of PB in its programme budgeting; (3) a moderate direct correlation between the duration of PB in a municipality and the political experience of the mayor.

The findings are derived from a quantitative analysis of cases localised in a single country, and therefore interpretation requires an awareness of the context of local democracy in Slovakia. In this regard, any generalisation beyond the context under study needs to be considered with caution.

This research fills a gap in the role of PB in the context of sustainability, especially in the context of a post-communist country like Slovakia. It applies a quantitative approach to the analysis of PB, which is relatively rare in this field of study (qualitative case studies are predominant in PB research).

The purpose of this paper is to explore elites' prevalence in the process of participatory budgeting (PB) in a Ukrainian municipality.

The paper draws on the elite control and capture literature to examine the occurrence of unintended consequences resulting from the process of PB. Data for this case study are derived from document analysis and semi-structured interviews.

This study demonstrates how the involvement of a non-governmental organisation (NGO) promoted PB in a Ukrainian municipality. In the process of orienting politicians and administrators to PB, its normative benefits tend to be prioritised, whilst very little attention has been paid to making inhabitants aware of their role in the process of participatory decision-making. Although PB is intended to propagate good governance and accountability, it has in fact turned out to be a means of promoting corruption and furthering the personal interests of rent-seeking actors.

The paper demonstrates how elites can capture and control PB in the context of emerging economies, thereby preventing its propagated benefits of ensuring equality, justice and emancipation in local communities from being realised.

Exploring PB in Ukraine, the authors urge that caution should be exercised with regard to the wholesale adoption of externally/NGO-propagated ideas. Each emerging economy context is distinct, and an appreciation of this uniqueness is key to the success of PB reforms in different countries.
