This paper examines the legislative recruitment of women from conservative Islamist parties. It questions the common assumption that generally all Islamist parties are equally hostile to political participation and representation of women. For this purpose, two of the electorally most successful Islamist groups in the MENA region are compared, namely the Egyptian Muslim Brotherhood (MB) and its Moroccan offshoot, the Party of Justice and Development (PJD). The article seeks an explanation for diverging trends in female candidacy between these conservative religious movements, using the traditional supply and demand model of candidate selection. It argues that the less centralized and the more institutionalized parties (as is the case with the PJD) seem to be better equipped to facilitate women’s candidacy than the more oligarchic ones (the MB). In order to fully grasp the reasons behind the diverging trends in the nomination of female candidates from both Islamist parties, cultural factors are scrutinized as well. The article highlights the limits of the supply and demand model of candidate selection, which cannot explain instances of unexpected change in recruitment strategies based on external interference. Furthermore, it does not provide us the means to assess the impact of individual candidates’ ‘feminist credentials’ on overall female representation.

This chapter examines the progress of women's participation and representation in the House of Commons. It first considers women's descriptive representation in the House of Commons over the last century, with emphasis on the differences in the proportion of women Members of Parliament (MPs) elected by the main political parties. It explains improvements in the numbers of women MPs in the last decade or so, together with the party asymmetry, by reference to the supply and demand model of political recruitment. It then reviews arguments for women's equal participation in politics, taking into account how women's descriptive representation intersects with symbolic and substantive representation. It also discusses resistance to the claim that women's representation matters and concludes with an analysis of the masculinized nature of the political institution that women MPs inhabit, along with the recommendations made in the 2016 The Good Parliament report.

This contribution takes a look back at the supply and demand model of selection and recruitment, developed by Joni Lovenduski and Pippa Norris in Political Recruitment: Gender, Race and Class in the British Parliament (1995). The core understanding of this model was that candidate selection was an interactive process in which both selectors and aspirants affected outcomes that were organized in several sets of institutions. The model illuminates power in particular institutions – British political parties – and was designed to examine the various effects of the selection process. This contribution reflects on the model and puts forward ideas and arguments about what might be done differently, taking into account the theoretical and methodological innovations of the succeeding generation of scholars who have used the model. It also identifies remaining challenges for research on candidate selection and suggests that the supply and demand model is sufficiently flexible that it can still travel across national, system and party boundaries.

In this paper a regional supply and demand model for hospital admissions is developed which can be used for policymaking and planning purposes. It incorporates spatial factors such as travel-time costs into a model of market equilibrium in which waiting time acts implicitly as the equilibrating device. By distinguishing travel-time costs or distances it is shown that both supply and demand within local markets strongly influence admissions in a way which cannot be observed on aggregated levels: the tension between supply and demand is cushioned by a strong redistribution of patients. The model encompasses several well-known models for patient flows and hospital utilization originating in regional economics.

The growing problem of obesity in the U.S. has prompted calls for government action, including the imposition of a "fat tax." The author uses microeconomic theory and a cost-benefit framework to explore the pros and cons of a fat tax. She applies theories of rational and irrational consumer decision-making to obesity-related consumption decisions and presents a simple supply and demand model to suggest the likely consequences of a fat tax. The author concludes that, before implementing a fat tax, additional research is needed to determine if a fat tax is merely the latest fad or a significant policy initiative that will make real contributions to correcting a major health problem in the United States.

AbstractReplication stress is a common feature of cancer cells, and thus a potentially important therapeutic target. Here we show that CDK-induced replication stress is synthetic lethal with mutations disrupting dNTP homeostasis in fission yeast. Wee1 inactivation leads to increased dNTP demand and replication stress through CDK-induced firing of dormant replication origins. Subsequent dNTP depletion leads to inefficient DNA replication, Mus81-dependent DNA damage, and to genome instability. Cells respond to this replication stress by increasing dNTP supply through Set2-dependent MBF-induced expression of Cdc22, the catalytic subunit of ribonucleotide reductase (RNR). Disrupting dNTP synthesis following Wee1 inactivation, through abrogating Set2-dependent H3K36 tri-methylation or DNA integrity checkpoint inactivation results in critically low dNTP levels, replication collapse and cell death, which can be rescued by increasing dNTP levels. These findings support a ‘dNTP supply and demand’ model in which maintaining dNTP homeostasis is essential to prevent replication catastrophe in response to CDK-induced replication stress.

This study examines mergers in two-sided markets using a structural supply-and-demand model that employs data from the 1996–2006 merger wave in the US radio industry. In particular, it identifies the conflicting incentives for merged firms to exercise market power on both listener and advertiser sides of the market, and disaggregates the effects of mergers into changes in product variety and advertising quantity. Specifically, it finds 0.2 percent listener welfare increase (+0.3 percent from increased product variety, and −0.1 percent from decreased ad quantity) and 21 percent advertiser welfare decrease (−17 percent from changes in product variety, and −5 percent from decreased ad quantity).

Energy as a strategic resource has become a crucial world issue, to sustain future economic growth and survival. The world depends for 95% of its total energy demand, on fossil fuel, supplies of which are limited, while world energy demand is increasing steadily along with population and economic growth. The West depends heavily on oil from the Middle East, and this has placed OPEC countries in a position to demand a twentyfold increase in crude oil prices in nine years. Alternative energy sources are discussed, but the world is still heading for a crisis due to imbalance between energy supply and demand. The energy situation in South Africa differs somewhat because local coal provides 80% of total energy requirements, and stringent conservation measures have achieved large reductions in oil consumption, while uranium, electricity generation and oil-from-coal technologies make the country less vulnerable than most other western countries.Energie as 'n strategiese hulpbron het wereldwyd krities geword, om toekomstige ekonomiese groei en oorlewing te verseker. Vir 95% van sy totale energieverbruik is die wereld afhanklik van fossielbrandstof, waarvan voorrade beperk is, terwyl die wereldvraag na energie steeds met bevolkings- en ekonomiese groei styg. Die Weste moet na die Midde-Ooste opsien vir olie, en dit het OPEC-lande in staat gestel om ruoliepryse in nege jaar twintigvoudig te verhoog. Alternatiewe energiebronne word bespreek, maar die wereld stuur steeds af op 'n krisis weens wanbalans tussen energievraag en -aanbod. Die energiesituasie in Suid-Afrika verskil ietwat omdat plaaslike steenkool 80% van totale energie benodig, verskaf, terwyl streng besparingsmaatreels groot vermindering in olieverbruik meegebring het, en uraan-, elektrisiteit- en olie-uitsteenkool-tegnologiee die land minder kwesbaar maak as meeste ander Westerse lande.
