Employment and absenteeism in working-age persons with multiple sclerosis

Aims: To better understand the impact of the clinical course of multiple sclerosis (MS) and disability on employment, absenteeism, and related factors.

Materials and methods: This study included respondents to the North American Research Committee on Multiple Sclerosis Registry spring 2015 update survey who were US or Canadian residents, aged 18–65 years and reported having relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), or primary progressive MS (PPMS). The RRMS and SPMS participants were combined to form the relapsing-onset MS (RMS) group and compared with the PPMS group regarding employment status, absenteeism, and disability. Multivariable logistic regression was used to examine the relationship between employment-related outcomes and factors that may affect these relationships.

Results: Of the 8004 survey respondents, 5887 (73.6%) were 18–65 years of age. The PPMS group (n?=?344) had a higher proportion of males and older mean age at the time of the survey and at time of diagnosis than the RMS group (n?=?4829). Female sex, age, age at diagnosis, cognitive and hand function impairment, fatigue, higher disability levels, ≥3 comorbidities, and a diagnosis of PPMS were associated with not working. After adjustment for disability, the employed PPMS sub-group reported similar levels of absenteeism to the employed RMS sub-group.

Limitations: Limitations of the study include self-report of information and the possibility that participants may not fully represent the working-age MS population.

Conclusions: In MS, employment status and absenteeism are negatively affected by disability, cognitive impairment, and fatigue. These findings underscore the need for therapies that prevent disability progression and other symptoms that negatively affect productivity in persons with MS to enable them to persist in the workforce.     

Water Resources in the Asia-Pacific Region: Managing Scarcity

Irrigation, together with improved crop varieties and substantial growth in fertiliser use in the late 1960s through the early 1980s, was a key factor in stimulating strong agricultural growth in much of the Asia-Pacific region. New sources of water are increasingly expensive to exploit, but irrigation continues to be a major catalyst for agricultural growth. In the face of increasing degradation, the maintenance of the water resource base must be a high priority policy objective. This paper reviews the management of water resources in the Asia-Pacific region, for countries with significant irrigated area: Cambodia, China, Indonesia, Korea-DPR, Republic of Korea, Laos, Malaysia, Mongolia, Myanmar, Philippines, Thailand and Vietnam.     

Dealing with Wicked Issues: Open Strategizing and the Camisea Case

The purpose of this article is to demonstrate, based on an extensive study of the Shell-led Camisea gas project in Peru, how what we believe to be a new approach to dealing with stakeholders, focusing on sense-making and combining industry dynamics and stakeholder empowerment, was developed. The project’s success was measured by the fact that, unlike similar projects around the world, it did not meet with major opposition during its 4-year life span. Those involved in the Camisea project succeeded in creating an open approach to building stakeholder relationships, allowing them to navigate through a number of diverse and challenging socio-political and ecological issues. An integral part of Shell’s approach was acting upon its commitment to high standards of operation and values. The insights from this case clearly indicate that stakeholder management and theorizing can profit from a less controlled, open and sense-making oriented strategizing with stakeholders.     

An oligopoly model of ocean liner shipping

In this paper I develop a simultaneous equations oligopoly model of the regulated international ocean liner shipping industry. The firms act as a cartel to determine price jointly and then set their own quality levels to maximize individual profits. The cartel does not attain monopoly profits, because each conference member myopically determines quality without regard for overall cartel profits. The results indicate that an increase in the number of firms in the cartel will increase both cartel price and quality level. An increase in price will also lead to an increase in quality level.I would like to thank Professors Alamarin Phillips, Robert Summers, and Bruce Allen for their helpful comments on earlier research for my dissertation in the Economics Department of the University of Pennsylvania on which this work is based. I am especially grateful to Professor Lawrence J. White for his encouragement and valuable suggestions at various stages of my work.     

CEO Share Ownership and Firm Value

This study examines the effect of CEO ownership on firm performance. The findings suggest that CEO ownership and firm performance are jointly determined. Firm performance affects CEO ownership positively and in turn, CEO ownership has a positive effect on firm performance. Our results also show that firms managed by founder CEOs have better performance and that the CEO duality structure is beneficial in a turbulent environment.     

What Belongs in a Constitution?

The essay argues that the content of constitutions should derive from its political functions: granting stability and legitimacy to government. There are three main candidates for inclusion in constitutions: regime arrangements, human rights, and general credo. All constitutions must include institutional arrangements. The level of detail and entrenchment may vary. There are important reasons for including Bills of rights in constitutions, but attention should be given to their mode of entrenchment and enforcement. Credos should only be included in constitutions if they are widely shared. In principles, constitutions should specify their modes of amendment and enforcement. If a society cannot have a widely-agreed constitution, it may be better to defer its enactment until such broad agreement is possible.     

The Effect of Subsidized Housing on Values of Adjacent Housing

This is a case study of the effect of subsidized housing on the value of adjacent non-subsidized housing. Four townhouse clusters in Fairfax County, Virginia, were selected for study because of the high degree of homogeneity between clusters. The clusters are all in the same community but vary in distance from subsidized housing. Sale prices were analyzed using a regression model which included distance from subsidized housing as an independent variable. Based on the results of the regression analysis, the authors conclude that the subsidized housing had a negative impact on the values of adjacent properties.
