Since the late 1970s, occupant fatalities in U.S. large truck accidents have generally shifted from truck occupants to occupants of other vehicles (primarily autos and light trucks). This paper analyzes that shift by estimating a regression model of a death ratio (other vehicle occupant fatalities to truck occupant fatalities) using annual time-series data for the 1975-1999 period. The regression includes two ratio explanatory factors-car size to truck size, and nontruck vehicle miles to truck vehicle miles-and one non-ratio explanatory variable, the proportion of young drivers. The vehicle size ratio has a statistically significant negative relationship with the death ratio (i.e., an increase in the size ratio contributes to a shift from other vehicle occupant deaths to trucker deaths); and the vehicle miles ratio has a significant positive association with the fatality ratio (i.e., an increase in the vehicle miles ratio promotes a shift from trucker fatalities to other vehicle occupant fatalities). The proportion of young drivers has a significant negative relationship with the fatality ratio.

Existing literature has explored the role of mindfulness and mind-wandering on creative processes. However, it has overlooked the diversity in the creative domains as well as the experience of the artist while accounting for their relationship. In the present study, mindfulness and mind wandering- deliberate and spontaneous were explored among performing artists, i.e. musicians, theatre artists, and dancers. The study also looked at the artists’ experience in their field. After an initial screening using a creativity tool, 66 performing artists were recruited, following which two self-report indices that assessed mind wandering and mindfulness were administered. The data collected was subjected to quantitative data analysis in SPSS. A Oneway ANOVA showed significant effect of the creative domain on mindfulness for the three groups, with a significant difference between musicians and dancers. Among the musicians, a significant negative relationship between mind wandering spontaneous and years of experience was seen. Among the dancers, there was a significant positive association between mind wandering spontaneous, mind wandering deliberate and years of experience. The current study highlighted the need to approach the study of creativity using a contextual perspective. Keywords: Creativity, Dance, Music, Theatre.

The present study examined the role of self-enhancement and self-criticism in the relationship between physical activity and anxiety. A total of 305 students from Chinese universities, ranging in age from 18 to 36, completed a questionnaire package comprising a physical activity questionnaire, a self-enhancement strategies scale, a level of self-criticism scale, and a short form of state and trait anxiety scale. Findings highlighted that physical activity had a significant negative correlation with anxiety (r = −0.31, p < 0.01), a significant positive association with self-enhancement (r = 0.43, p < 0.01), and a significant negative relationship with self-criticism (r = −0.14, p < 0.05). It was also found that anxiety was significantly predicted by self-enhancement (−0.21, p < 0.01) and self-criticism (0.44, p < 0.01). Moreover, the mediation model supports the mediation of self-enhancement and self-criticism between physical activity and anxiety in university students. The findings suggest that interventions aimed at promoting physical activity and enhancing the self-system should be worthy strategies for reducing students’ anxiety.

Some economic problems facing by any economy are addressed such that minimum levels of these are acceptable. Inflation and unemployment are among such macroeconomic issues of which certain minimum level of both are accepted by economists. Nature of relationship between unemployment and inflation is important in economic literature. This study was performed to find this nature for a developing country. Time series data on both variables was analyzed for Pakistan from 1974 to 2010. ADF test was applied for detection of non-stationary. Problem of non-stationary was detected when variables were at level, which was eliminated by taking variables at first difference. Johansen co-integration confirmed one cointegration vector, which suggested the presence of long run relation between variables. VECM was used to find short and long run estimates. A short run relation was witnessed when unemployment worked as dependent variable and inflation as explanatory variable. This model was in equilibrium and thirty five percent disequilibria were adjusted annually as ECT value suggested. Inflation had a significant positive association with unemployment in study period. This study supported the Locus critique as opposed to Phillips curve hypothesis. Policy makers should pay special attention to this relationship between inflation and unemployment when they are going to design macroeconomic policies for Pakistan’s economy.

The Relationship

This study is set to ascertain the relationship between the use of e-payment products and the value of currency in circulation in Nigeria. An ex-post facto research design was adopted in the investigation. A least square regression analysis was carried out on a time-series data. The objective was to ascertain relationships between the variables, whether positive or negative and to determine its significance. The outcome of the study indicates that only REMITA and WEBPAY have an inverse but significant negative relationship with currency in circulation in Nigeria. At the same time, the use of ATM and POS maintained a positive and significant relationship. This isn’t surprising considering ATM and POS machines are verified sources of cash withdrawals in Nigeria. Presently, due to the relatively low use of e-payment products, their influence on monetary policy has been insignificant. The Central bank of Nigeria has not recorded a decrease in currency in circulation followed by an increase in the use of e-payment products; instead, it is recorded that between 2009 and 2018, the value of currency in circulation grew by about 97.18%. It is important to stress the fact that any innovation takes time to mature and become accepted in the market. It might be too soon to complain. We ought to expect that in the future, e-money products could be made more acceptable as regular payment instruments. Following this, their influence on monetary policy could be increased. This depends on the extent to which it will substitute the currency in circulation. This means that a developing nation like Nigeria needs to monitor the trend of development of e-money on the market and the increasing degree of use by institutions and clients. Lastly, the regulatory authorities need to develop the capacity to manage an e-money driven economy more closely and more carefully.

The financial sector is considered as vital in the process of growth of economies both developed and developing. Economists and researchers have sough to investigate the relationship between duo with conflicting and incnclusive results. Hence, in a developing country like Nigeria, the results remains same. Example,  Akinlo (2010) finds a significant positive relationship between development of the financial sector and economic growth. Other studies like Nyong (1997) find a significant negative relationship between finance and economic growth.Therefore, this study seeks to re-examine the relationship between Nigeria’s finance and economic growth using annual time series data from 1981 to 2015. Similarly, it seeks to find out if there exist a structural break in the data and whether it matters in determining the relationship between finance and economic growth.The study finds a signifcant negative relationship between finance and econmic growth after accounting for structural break  and that inclusion of break in the estimated model enhance its performance.The study recommends that future macroeconomic studies should check for breaks and if present be considered in estimation of such models.

This study is an endeavor to examine joint determination of prices, money supply and output in Pakistan during 1975-2019 by using macro-economic model and annual time series data. Three Stage Least Square (3SLS) method is utilized to estimate simultaneous model of prices, money supply and output nexus. Our results strongly support significant positive association between prices and money supply thus supports monetarist view that growth in money supply causes inflation and rising behavior of prices is detrimental to real output. The accelerated inflation has obstructed real output and reduced output levels has further caused jump in price levels during the investigated period. The empirical results also supports significant bi-directional relationship between prices and money supply. Prudent monetary policy is need of hour to stabilize prices in order to minimize its adverse impacts on real output.

This study empirically investigates the effects of macroeconomic disequilibrium on educational development in Nigeria. The study employed time series data between 1980 and 2017. Autoregressive Distributed Lag method of estimation was employed. The result revealed that the variables stationarity test were mixed between the first difference I(I) and level I(0). The cointegration result shows that there exist long run relationship between the variables. The result revealed that Balance of payment, Poverty, Debt rate inflation and unemployment exhibited negative relationship with educational development. The estimation result showed that all explanatory variables account for 88% variation of educational development in Nigeria. It is therefore recommended that government should fast track policies that can stabilize inflation and exchange rate in the country. Also, Policies must be formulated to reduce poverty and unemployment.

This study examined the relationship between budget deficit and economic growth in Ethiopia using time series data for the period 1991 to 2019 by applying the ARDL bounds testing approach. The empirical results indicate that budget deficit and economic growth in Ethiopia have a negative relationship in the long run, and have a weak positive association in the short run. In line with this, in the long run, a one percent increase in the budget deficit causes a 1.43 percent decline in the economic growth of the country. This result is consistent with the neoclassical view which says budget deficits are bad for economic growth during stimulating periods. Moreover, in the long run, the variables trade openness and inflation have a positive impact on Ethiopian economic growth, and on the other hand, the economic growth of Ethiopia is negatively affected by the nominal exchange rate in the long run. Apart from this, in the long run, gross capital formation and lending interest rates have no significant impact on the economic growth of the country. Therefore, the study recommends the government should manage its expenditure and mobilize the resources to generate more revenue to address the negative impact of the budget deficit on economic growth.

Research on health and political behavior has identified a significant mental health-participation gap that is likely to have important consequences for political equality. Yet such consequences remain by and large unexplored. Inspired by 60 years of empirical research on public opinion, media and policy, this article proposes a roadmap for research on the political representation of mental health. It advances a number of research questions around 1) opinion formation and issue emergence and evolution, 2) multiple and complementary societal signals that can influence policy makers’ issue attention and policy change, and 3) different conceptions of representation and their consequences for public attitudes and political participation. The article also provides a preliminary attempt at addressing whether mental health spending incorporates signals from public preferences for spending on mental health services or policy problems. Making use of time-series data on spending on mental health services by local authorities in England between 1994 and 2013, the analysis finds no statistical association between spending and policy problems and reveals a negative relationship between spending and public preferences, suggesting that if spending is reacting at all to preferences, it misrepresents them. This article invites scholars to collect more data and produce more research that will guide interventions to help overcome stigma and participation challenges that undermine political equality as one of the key principles of democracy.

The Relationship

Purpose – The purpose of this paper is to investigate the relationship between FDI and economic growth. Two models have been used to analyse the time series data on Pakistan from 1970 to 2012. This paper contributes to the existing literature by examining the different empirical methods to estimate the relationship between FDI and economic growth. The vector error correction model (VECM) results suggest that FDI depends on the economic growth but this relationship is not true vice versa. The second model showed that FDI, human capital and exports are important factors of economic growth. However, the negative relationship between interactive variables (FDI and human capital) and economic growth indicates that low level of human capital affect the economic growth of Pakistan. Design/methodology/approach – Used time series data (1970-2012) for empirical analysis. Findings – The VECM results suggest that FDI depends on the economic growth but this relationship is not true vice versa. The second model showed that FDI, human capital and exports are important factors of economic growth. However, the negative relationship between interactive variables (FDI and human capital) and economic growth indicates that low level of human capital affect the economic growth of Pakistan. Research limitations/implications – The limitations of this empirical paper are as follows: it would be better to use secondary school enrolment (per cent) to measure human capital instead adult literacy rate. Similarly, the non-availability of R & D data on Pakistan limited the scope of the paper to measure the role of absorptive capacity of domestic and its relationship with FDI. The results of this paper are specifically related to Pakistan and cannot be generalized to other countries. Practical implications – This empirical study implies that Pakistan should improve its economic growth. The robust policies are required to increase the literacy rate of the country. Higher human capital will attract more FDI into the economy and may reduce the unemployment. This would increase the national output of the country and their national income level. Presently, Pakistan is going through war on terror and foreign firms are reluctant to invest. A stable and secure business environment will ultimately inject foreign direct investment into Pakistan. Originality/value – This paper is first time analyse the time series data to explore the relationship between FDI and economic growth. A new approach has been used called VECM.
