Abstract

Purpose

The purpose of this paper is to examine the effects of several structural shocks in oil prices on the Vietnamese economy and answer three key research questions: Is there a relationship between oil price shocks and macroeconomic indicators in Vietnam? How do different types of oil price impulses affect Vietnamese inflation and economic performance? To what extent do structural shocks in oil prices explain variations in Vietnam’s macroeconomic indicators?

Design/methodology/approach

Lower triangular Cholesky decomposition is performed on a short-term impact matrix in a two-block structural vector autoregressive model. The data set is defined monthly, from January 2000 to December 2021. The contributions of structural shocks in oil prices to the domestic variances are analysed using variance decomposition methods. In this study, both forecast error variance decomposition and historical decomposition are used.

Findings

The consequences of oil price fluctuations on Vietnamese output and inflation depend on different sources of oil price shocks. In comparison, oil supply shocks have an insignificant effect on both domestic industrial output and consumer price index inflation; however, positive shocks in aggregate and precautionary oil demands increase these domestic indicators substantially and sustainably. An analysis of variance decompositions reveals that supply-side oil shocks have very limited explanatory power for variations in domestic variables. Nevertheless, the contributions of unanticipated demand-side booms to domestic variations in the past and projected forecasts are considerable.

Research limitations/implications

The findings from this research uncover potential risks for Vietnam’s economic prospects if the consequences of oil price shocks are not managed effectively.

Originality/value

Given the lack of economic sensitivity to supply-side oil shocks and the strong response to shifts in oil demands, greater pressure on the domestic economy is likely when Vietnam increases its dependence on oil imports.

Abstract

Purpose

The purpose of the study is to design economical shock tube. It is an instrument used for experimental investigations not only related to shock phenomena but also for the behavior of the material when it is subjected to high-speed flow. The material used here in this shock tube is stainless steel ss304 and aluminum. A shock tube consists of two sections, namely, the driver and the driven. The gas in the driven and driver is filled with atmospheric air and nitrogen, respectively, under the predominant condition.

Design/methodology/approach

The focus of the study is on the design and fabrication of shock tubes. a shock tube is a research tool to make an aerodynamic test in the presence of high pressure and temperature by generating moving normal shock waves under controlled conditions.

Findings

The main necessity for instrumentation in the shock tube experiment is to know the velocity of the moving shock wave from which the other parameters can be calculated. the pressure transducers are located in the shock tube in various locations to measure aerodynamic parameters in terms of pressure.

Originality/value

The main objective of this project work is to make an experimental setup to produce supersonic velocity with the readily available material in the market in a highly safe manner.

Abstract

Purpose

The purpose of this explorative study is to investigate through the lens of gender the role of career shocks in career advancement experiences in academia. By taking a contextual approach, this study increases understanding of the role of the academic career script as a potential boundary for career shock implications.

Design/methodology/approach

The authors studied career advancement experiences of a cohort of 75 men and women associate professors in the Netherlands via biographical interviews and conducted theoretically informed inductive analysis.

Findings

The analysis revealed the ambiguities and contradictions in the role of most career shocks in career advancement experiences. Failure to fit the majority of career shocks into the “rigid” academic career script generates discretionary latitude in handling shocks. These shocks pose unique barriers – and to a lesser extent unique benefits – to women's perceived opportunities for career advancement.

Practical implications

Academic organizations should focus on cultivating more inclusive work environments with respect to career shocks. The 75 diverse biographies offer leverage to challenge traditional notions of academic career advancement.

Originality/value

This paper extends “structure and agency” literature on career building by showing how career shock implications are inherently contextual in the academic setting. Gendered support provisions for handling career shocks offer a novel explanation for the numerical minority of women in academic leadership.

Abstract

Purpose

The COVID-19 crisis caused a high level of job insecurity, layoff and low employment opportunities. It generated a worldwide shock, which might have a long-lasting effect on individuals' careers. Changes might occur in terms of individuals’ career choices, objectives, perception of career success and preferences in terms of industries and work arrangements. This study aims to examine crisis-induced career shock among the workforce, which might be translated into changes or doubts related to career choices, objectives and perception of career success, and to analyze individuals' preferences in terms of industries and work arrangements. It focuses mainly on investigating variations among the workforce, based on gender, education level and ethnic origin. These variations are also examined regarding job insecurity, layoff and perceived employability.

Design/methodology/approach

Frequency counts, percentages, mean ranking, independent t-test and analysis of variance (ANOVA) were used for a sample of 317 workers in the United Arab Emirates (UAE). Three research questions were developed and examined, which are: (1) is there a variation in the workforce, based on gender, education level and ethnic origin concerning crisis-induced career shock (specifically changes related to career choices, objectives and career success? (2) Is there a variation among the workforce related to career preference per industry and work arrangement? If yes, is there a difference in the workforce-based gender, education level and ethnic origin? And (3) is there a variation in the workforce, based on gender, education level and ethnic origin concerning job insecurity, layoff and perceived employability?

Findings

The findings revealed that career shock was significantly higher among pre-university respondents (specifically, doubts about career choices and perceived career success). As for career preferences per industry, e-business, media and marketing had significant values for all respondents, with e-business as the top-rated choice except for Emiratis who rated it as their third choice. Education was the choice of both men and women. The choices related to other industries (e.g. Healthcare, information, communication technology, etc.) and work arrangements (telework) varied significantly based on gender, education and ethnic origin. Men seem to worry more than women about losing their job as well as Emiratis compared to expatriates, and university-level respondents compared to pre-university.

Practical implications

This study contributes to highlighting variations related to career shock and career preferences per industry among the workforce based on gender, education level and ethnic origin. This can help organizations in these industries to have a portrait of the situation in the employment market to be able to develop relevant interventions. This research provides insights for managers and HRM practitioners.

Originality/value

This study contributes to expanding research on career and career shocks in a context of a crisis. It responded to authors who called for more research about career shocks, as well as their implication for specific target groups, by examining variations based on gender, education level and ethnic origin.

Abstract

Purpose

The purpose of this paper is to generalize Yeh and Zhang's 2004 random threshold failure model for deteriorating systems.

Design/methodology/approach

An N‐policy was adopted by which the system was replaced after the Nth failure.

Findings

The model was found to have practical applications in warranty cost analysis.

Originality/value

By identifying the instance of a shock as the failure of the system and the threshold times as the warranty period offered and changing the definition of lethal shock (system failure in this case) as the occurrence of a shock within a threshold period in our generalized model, one can study the renewing warranty cost analysis.

Abstract

UK regional data on GDP and the GDP deflator are analysed to extract information on underlying demand and supply shocks as well as aggregate demand and supply shocks. Identification is achieved using long run restrictions, based on a theoretical model. The main results are that the supply shocks are almost completely symmetric across UK regions and that there is no evidence of these shocks being propagated slowly across the regions.

Abstract

Purpose

The main purpose of this paper is to investigate the dynamic effects of the oil price shocks on Iran’s inflation in the period 1993:2–2018:2

Design/methodology/approach

The main purpose of this paper is to investigate the dynamic effects of the oil price shocks on Iran’s inflation in the period 1993:2–2018:2 using the time-varying parameter vector autoregressive (TVP-VAR) model. The dynamics of the results enable us to study the amount and severity of the impact of the oil price shocks on inflation with the distinction of the sanctioned and non-sanctioned periods. The volume of oil export is used to identify the effective oil sanctions. The period is divided into sanctioned and non-sanctioned periods by Markov switching model.

Findings

The results show that the pass-through of oil price shocks into Iran’s inflation are time-varying, and there are significant differences at sanction period from other time horizons. An increase in oil price has a positive effect on inflation and its effects are stronger during the sanctions period. It is also observed that the producer price index is more sensitive to changes in the oil price than the consumer price index. The necessity of the government’s earnest efforts to improve international relations to lift the sanctions, along with diversification of exports, and making the economy of Iran independent of oil revenues is obvious.

Originality/value

In addition to the exogenous oil price shocks, Iran’s economy faces numerous restrictions for its oil exports due to the sanctions. The main purpose of this paper is to investigate the dynamics effects of the oil price shocks on Iran’s inflation in the period 1993:2–2018:2 using the time-varying parameter vector autoregressive (TVP-VAR) model. The dynamics of the results enable us to study the amount and severity of the impact of the oil price shocks on inflation with the distinction of the sanctioned and non-sanctioned periods. The volume of oil export is used to identify the effective oil sanctions.

Abstract

Purpose

Through addressing female academics in four public universities in Egypt, the author of this paper aims to answer the question: How do female academics cope with the career shock resulting from the spread of COVID-19?

Design/methodology/approach

The author used a qualitative research method through semi-structured interviews with 32 female academics from four public universities selected from among 26 public institutions of higher education in Egypt. Thematic analysis was subsequently used to determine the main ideas in the transcripts.

Findings

The findings assert that the following three strategies: heroism, cronyism and temporalism are used by female academics in the Egyptian context to cope with the career shocks they feel during the time of COVID-19. The findings assert that female academics try to reassert their professionalism in their academic duties and familial obligations even after the spread of COVID-19. Moreover, they tend to use forms of cronyism behaviour to alleviate the effect of the career shock, mostly via hypocritical phrases. Furthermore, the thought that COVID-19 is a temporary stage helps female academics to actively accept their challenging new work conditions.

Originality/value

This paper contributes by filling a gap in human resources management and higher education in which empirical studies on the career shock of female academics have been limited so far.

Abstract

We document how inflation expectations evolved in the United States during the fall of 1933 using narrative evidence from historical news accounts and the forecasts of contemporary business analysts. We find that inflation expectations, after rising substantially during the spring of 1933, moderated in the fall in response to mixed messages from the Roosevelt Administration. The narrative accounts and our econometric model connect the dramatic swings in output growth in 1933 – the rapid recovery in the spring and the setback in the fall – to these sudden movements in inflation expectations.

Abstract

Taking a gender-sensitive approach, this study examines the socio-economic and institutional drivers of household vulnerability to the shocks occasioned by the COVID-19 pandemic. The study employs country-level panel data for Nigeria. Data collected were analysed using descriptive statistics, Pearson's chi-square, and ordered logistic regression. The study found significant heterogeneity in vulnerability to the COVID-19 shocks between the male-headed households (MHHs) and female-headed households (FHHs) (p < 0.1). The econometric results reveal that in the MHHs, the geographical location, livelihood diversification, and ownership of television were the significant drivers of vulnerability to COVID-19–related shocks. In the FHHs, credit constraints, household size, value of the household assets, geographical location, ownership of television and radio, and experiences of previous shocks were found to be significant drivers of vulnerability to COVID-19–related shocks. This study provides insights for designing inclusive social protection interventions and gender-sensitive COVID-19 recovery policies.
