Pattern of road traffic injuries in Ghana: Implications for control

Road traffic injuries and fatalities are increasing in Ghana. Police-collected crash and injury data for the period 1994-1998 were aggregated and analyzed using the MAAP5 accident analysis package developed by the Transport Research Laboratory, U.K. Published results of recent transport-related epidemiological and other surveys provided an additional data source. According to the 1994-1998 police data, road traffic crashes were a leading cause of death and injuries in Ghana. The other leading causes of death and injuries are occupational injuries which involve nonmechanized farming and tribal conflicts. The majority of road traffic fatalities (61.2%) and injuries (52.3%) occurred on roads in rural areas. About 58% more people died on roads in the rural areas than in urban areas, and generally more severe crashes occurred on rural roads compared with urban areas. Pedestrians accounted for 46.2% of all road traffic fatalities. The majority of these (66.8%) occurred in urban areas. The second leading population of road users affected was riders in passenger-ferrying buses, minibuses and trucks. The majority of these (42.8%) were killed on roads that pass through rural areas. Pedestrian casualties were overrepresented (nearly 90%) in five regions located in the southern half of the country. Efforts to tackle pedestrian safety should focus on the five regions of the country where most pedestrian fatalities occur in urban areas. Policies are also needed to protect passengers in commercially operated passenger-ferrying buses, minibuses and trucks because these vehicles carry a higher risk of being involved in fatal crashes.     

DEUS CARITAS EST: THE SOCIAL MESSAGE OF POPE BENEDICT XVI

The first encyclical letter of Pope Benedict XVI contains many surprises, not least among which are observations about the nature of justice, the limits of the state, and the purpose and character of charitable organisations. This article analyses the encyclical by highlighting some of its underlying theological and philosophical influences as well as its practical implications for how Christians think about approaching poverty and the political order.     

Spatial inequality and household poverty in Ghana

The study analyses district-level consumption inequality in Ghana, explores the relative contribution of within- and between-district inequalities to national inequality and examines the relationship between household poverty and inequality. The last three rounds of the Ghana Living Standard Survey are used. We observe that the contribution of within-district inequality to national inequality is higher than inequality between districts. Also, district-level consumption inequality shows a significant effect on household poverty, but with varying signs. We surmise that the variation in signs is as a result of the state of economic activity and factors that affect both poverty and inequality.

Hiring an innovative workforce: A necessary yet uniquely challenging endeavor

To increase innovative performance in work settings, most scholars agree that organizations need both an environment that is supportive of creativity as well as employees with high levels of creative potential. Substantial research effort has been aimed at understanding work contexts that facilitate creative thinking, yet less is known regarding how to most effectively recruit and hire creative talent. To fill this knowledge gap and guide future research efforts, we discuss the KSAOs most predictive of creative potential as well as the means and methods for assessing this potential. In addition, we explore the challenges to quantifying successful innovation, proposing that creative achievement represents a unique and specialized form of organizational performance. Supplementing this discussion we provide recommendations for obtaining high-quality, substantive criterion data. We conclude with a brief discussion on recruitment and long-term selection strategies for innovation.     

The systematic pricing of market sentiment shock

ABSTRACT

We show that market sentiment shocks create demand shocks for risky assets and a systematic risk for assets. We measure a market sentiment shock as the unexpected portion of the University of Michigan Consumer Sentiment Index’s growth. This shock prices stock returns in arbitrage pricing theory framework at 1% after controlling for market, size, value, momentum, and liquidity risk factors. Its premium lowered the implied risk aversion by 97.9% to 11.46 between 1978 and 2009 in our sentiment consumption-based capital-asset-pricing model. Merton’s [1973. “An Intertemporal Capital Asset Pricing Model.” Econometrica 41: 867–887]. intertemporal capital-asset-pricing model reconfirms our finding that this market sentiment shock is a systematic risk factor that provides investment opportunities.     

Segmentation Analysis of the Volunteering Preferences of University Students

The purpose of this article is to explore how universities can increase volunteering among their students. To accomplish this objective, conjoint anlaysis was undertaken to determine the different underlying needs and preferences that drive the volunteering behavior of students. From this data, four need‐based segments are identified and discussed. Strategies are then formulated to meet the needs and preferences of each segment as a means to increase volunteering on campuses.
