An evaluation of Nigerian ports post-concession performance

Purpose: The quest for efficiency is claimed to be the major objective of port privatisation and this has led many ports in Africa to undertake port reforms. Based on this, Nigerian ports were concessioned and operations were handed over in one scoop to private operators between 2006 and 2007. This paper is looking to investigate in the reform that took place in a very short period of time improved the performance of Nigerian ports. This paper is also looking to provide a model for future evaluation. Research Approach: A window based DEA model with panel data will be employed to measure pre- and post concession Nigerian ports' performance to determine efficiency gains from port reform. Secondly, to demonstrate how concession influence efficiency, a DEA based Malmquist productivity Insex will be used to determine the sources of (in)efficiency by decomposing the efficiency into frontier shift effects and catch-up effects. Findings and Originality: The results revealed that none of the ports is hundred percent efficient before and after concession but rather a tremendous increase in throughput and ship traffic after the reform in most of the ports. Apapa port is the most efficient while Calabar and Warri are inefficient although there were fluctuations in efficiency in all the ports. The research is inconclusive because it is still ongoing Although some studies have investigated the relationship between port efficiency and privatisation however several gaps still exist as the studies are skewed in favour of container ports in the developed world, mainly in Europe. Therefore, the need arises to critically look at the overall efficiency of national port system to enhance the efficiency of global transport chain. Research Impact: The study will contribute to existing literature on port performance being the first to evaluate the post concession performance of a major maritime player in Sub-Saharan Africa. It will contribute to the never- ending debate by the Academia on the effect of ownership or privatisation on efficiency from the perspective of port institutional reforms in the third world countries Practical Impact: It will benefit the Federal Government of Nigeria as a reference document of the first five years of the port reform policy and help the Government to intervene in areas of observed inefficiencies and make adjustments where possible. On the part of the "Landlord" NPA it will help them in the performing their regulatory role by identifying the operators who are making inefficient use of the resources allocated to them and provide the basis for future evaluation. Finally, it will give the various stake holders in the Maritime Industry a full grasp of the effect of concession in a Nation's port as Nigeria is the first country in the world to hand over terminal operations in all her ports in one scoop

Opportunities for Producing Table Grapes in Egypt for the Export Market: A Decision Case Study

The Barakat Fruit Farm desires to increase their share of the exportable grape market in Egypt. Unfortunately, the grape cultivars currently cultivated by the farm bear fruit after the early market window to the European Union when prices are high. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case encourages students to think outside of traditional production techniques to arrive at solutions that are viable from both crop culture and financial standpoints.Decision case, horticulture, agriculture economics, grape production, Production Economics, Teaching/Communication/Extension/Profession, Q10, Q11,

Processed Chili Peppers for Export Markets: A Capital Budgeting Study on the AgroFood Company

The AgroFood Company, which currently exports fresh chili peppers to European clients, desires to expand the product mix offered. The company, as it expands its production of fresh peppers for export, has an increasing supply of grade 2 peppers that are unmarketable in Egypt. However, an attractive market for processed frozen chili peppers exists in Europe. To expand their client base, capitalize on a value added product, and minimize product waste, the AgroFood Company desires to develop processing practices for chili peppers produced in Egypt. The AgroFood Company would like to identify its options in the processed pepper market. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case will provide students with an opportunity to evaluate the merits of business expansion into a high capacity, automated mechanical processing facility for grade 2 vegetables.Decision case, horticulture, agriculture economics, chili pepper production, protected vegetable production, Crop Production/Industries, Food Security and Poverty, Production Economics,

The strategic impact of airline group diversification: the cases of Emirates and Lufthansa

The airline industry is a diverse sector, requiring the support of a varied range of ancillary businesses such as maintenance, catering and travel agencies to carry out its activities. Many of these supporting businesses demonstrate the potential to drive wider profit margins despite generating lower revenues than the airlines themselves, making them attractive investment opportunities in a sector prone to volatile and often lacklustre trading. This study investigates two of the largest diversified airline groups, Germany's Lufthansa Group and Dubai's Emirates Group, each adopting a distinct approach towards diversification that may serve as a model for airline groups worldwide. The areas investigated were Cargo, Maintenance, Catering and Travel Services. The research found that whilst diversification may not always present the most attractive option financially, strategic factors can often outweigh such concerns. Business units studied were found to have variable prospects; particularly in the case of Catering, a sector on the rise – versus in-house Maintenance, which for airlines, is likely to see decline. The pursuit of third party revenue streams to offset weak internal trading and growth in competencies were found to be the key drivers of success. Interplay between segments was also apparent, showing that a well-organised diversification strategy can achieve robust cross-functional benefits and deliver significant value to the parent organisation

Urinary Tubular Injury Biomarkers Are Associated With ESRD and Death in the REGARDS Study.

IntroductionUrinary neutrophil gelatinase-associated lipocalin (uNGAL) and urinary kidney injury molecule-1 (uKIM-1) are established markers of subclinical acute kidney injury. In persons with reduced estimated glomerular filtration rate (eGFR) and albuminuria who are at high risk for end-stage renal disease (ESRD) and death, the associations of these urinary markers with incident ESRD or death is an area of active investigation.MethodsAmong 1472 black and white participants from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study with eGFR ≤60 ml/min per 1.73 m2 (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] cystatin, 2012) and albumin-to-creatinine ratio (ACR) ≥30 mg/g, we evaluated the associations of baseline uNGAL and uKIM-1 with progression to ESRD and all-cause death. Cox models were sequentially adjusted for urinary creatinine, traditional risk factors, C-reactive protein, ACR, and eGFR.ResultsThere were 257 ESRD events and 819 deaths over a median follow-up of 5.7 and 6.5 years, respectively. In demographic adjusted models, higher levels of uNGAL were associated with increased risk of ESRD and death, but these associations were attenuated in fully adjusted models including baseline eGFR for both ESRD (hazard ratio [HR] = 1.06 per doubling, 95% confidence interval [CI] 0.98-1.14) and death (HR = 1.04, 95% CI = 1.00-1.08). Higher levels of uKIM-1 were associated with increased risk of ESRD and death in demographic-adjusted models, and although attenuated in fully adjusted models, remained statistically significant for both ESRD (HR = 1.24 per doubling, 95% CI = 1.08-1.42) and death (HR = 1.10, 95% CI =1.03-1.19).ConclusionIn this cohort of high-risk patients with baseline eGFR ≤60 ml/min per 1.73 m2 and albuminuria, renal tubular injury is associated with higher mortality and progression to ESRD. Further studies are necessary to investigate the mechanism underlying this increased risk

Creating the ‘ethics industry': Mary Warnock, in vitro fertilization and the history of bioethics in Britain

Recent decades have seen a shift in the management and discussion of biomedicine. Issues once considered by doctors and scientists are now handled by a diverse array of participants, including philosophers, lawyers, theologians and lay representatives. This new approach, known as ‘bioethics', has become the norm in regulatory committees and public debate. In this article, I argue that bioethics emerged as a valued enterprise in Britain during the 1980s because it fulfilled, and linked, the concerns of several groups. My analysis centres on the moral philosopher Mary Warnock, who chaired a government inquiry into human fertilization and embryology between 1982 and 1984, and became a strong advocate of bioethics. I detail how Warnock's promotion of bioethics tallied with the Conservative government's desire for increased surveillance of hitherto autonomous professions – while fulfilling her own belief that philosophers should engage in public affairs. And I also show that Warnock simultaneously promoted bioethics to doctors and scientists as an essential safeguard against declining political and public trust. This stance, I argue, framed bioethics as a vital intermediary between politics, the public, and biomedicine, and explains the growth and endurance of what the Guardian identified as an ethics industry

Calibration uncertainty in molecular dating analyses: there is no substitute for the prior evaluation of time priors

Calibration is the rate-determining step in every molecular clock analysis and, hence, considerable effort has been expended in the development of approaches to distinguish good from bad calibrations. These can be categorized into a priori evaluation of the intrinsic fossil evidence, and a posteriori evaluation of congruence through cross-validation. We contrasted these competing approaches and explored the impact of different interpretations of the fossil evidence upon Bayesian divergence time estimation. The results demonstrate that a posteriori approaches can lead to the selection of erroneous calibrations. Bayesian posterior estimates are also shown to be extremely sensitive to the probabilistic interpretation of temporal constraints. Furthermore, the effective time priors implemented within an analysis differ for individual calibrations when employed alone and in differing combination with others. This compromises the implicit assumption of all calibration consistency methods, that the impact of an individual calibration is the same when used alone or in unison with others. Thus, the most effective means of establishing the quality of fossil-based calibrations is through a priori evaluation of the intrinsic palaeontological, stratigraphic, geochronological and phylogenetic data. However, effort expended in establishing calibrations will not be rewarded unless they are implemented faithfully in divergence time analyses

Organisational Trust: A Case Application in the Air Transport Sector.

From a management perspective, it is important to know what the likely feedback effects of efficiency drives might be on levels of employee trust. This paper looks to apply this important question to a case application in the air transport sector by testing the use of recent efficiency measures in a case sample of air transport companies using a modified aggregate trust model. The findings of this study suggest efficiency creating tactics do not lead to resentment and conditions of mistrust in themselves. Rather, occupational group (flight crew/non-flight crew), airline type (FSA,LCC, Charter), and level of seniority (management/non-management level) all have a more important bearing on the employee-employer relationship. Pre-existing labour agreements and legacy arrangements with senior and certain occupational groups were found to have a more damaging effect on the trust relationship than anything else. An underlying level of resentment and defensiveness has developed due to historical agreements being changed and have been observed most notably among FSAs, flight-crew and middle-management staff. The mediating role of the unions in the employee-employer trust relationship was found to be insignificant among the sampled air transport organisations
