Effects of ocean acidification on the larvae of a high-value pelagic fisheries species, mahi-mahi Coryphaena hippurus
No full textNegative impacts of CO₂-induced ocean acidification on marine organisms have proven to be variable both among and within taxa. For fishes, inconsistency confounds our ability to draw conclusions that apply across taxonomic groups and highlights the limitations of a nascent field with a narrow scope of study species. Here, we present data from a series of 3 experiments on the larvae of mahi-mahi Coryphaena hippurus, a large pelagic tropical fish species of high economic value. Mahi-mahi larvae were raised for up to 21 d under either ambient seawater conditions (350 to 490 μatm pCO₂) or projected scenarios of ocean acidification (770 to 2170 μatm pCO₂). Evaluation of hatch rate, larval size, development, swimming activity, swimming ability (U[subscript crit]), and otolith (ear stone) formation produced few significant effects. However, larvae unexpectedly exhibited significantly larger size-at-age and faster developmental rate during 1 out of 3 experiments, possibly driven by metabolic compensation to elevated pCO₂ via a corresponding decrease in routine swimming velocity. Furthermore, larvae had significantly larger otoliths at 2170 μatm pCO₂, and a similar but non-significant trend also occurred at 1200 μatm pCO₂, suggesting potential implications for hearing sensitivity. The lack of effect on most variables measured in this study provides an optimistic indication that this large tropical species, which inhabits the offshore pelagic environment, may not be overly susceptible to ocean acidification. However, the presence of some treatment effects on growth, swimming activity, and otolith formation suggests the presence of subtle, but possibly widespread, effects of acidification on larval mahi-mahi, the cumulative consequences of which are still unknown.This is the publisher’s final pdf.

Ribat-i Mahi (Khurasan-i Razavi, Iran): Evidence of a Saljuq Building Inscription
No full textThe ruin of Ribat-i Mahi has long been identified as an important site of the Middle Islamic period in Khurasan. Its position on the caravan route between Mashhad (Tus) and Marv fits with the development of long-distance relations between the Abbasid and the Timurid period. During the Saljuq period, this route saw major building activities, of which the caravanserai of Ribat-i Sharaf and the gateway of Do Barar are important remains. Ribat-i Mahi also figures in the secondary literature on Islamic architecture. It is frequently dated to the early 5th/11th century, on the basis of an episode transmitted by the 9th/15th century author Hafiz-i Abru. However, a stylistic comparison with Ribat-i Sharaf and with buildings in Marv (Turkmenistan) demonstrates that the extant ruin should be attributed to the Saljuq period. This dating receives new support from a photograph held in the Gulistan Palace archive. The picture, dated 1311/1893-94, shows the gate of Ribat-i Mahi with an inscription that has now vanished. In the text, the name of Sanjar b. Malikshah can clearly be identified. Parts of his royal titulature are subject to discussion, as well as the name of another person, who is probably to be identified with the vizier Sadr al-Din Muhammad b. Fakhr al-Mulk b. Nizam al-Mulk. From his biographical dates as they appear in written sources, the construction of Ribat-i Mahi would most likely to be dated between 500/1106-07 and 511/1117-18

Migrant Necropolitics at the Table: Civilized Cannibalism in Mahi Binebine\u27s \u3cem\u3eCannibales\u3c/em\u3e
No full textIn Cannibales, the Maghrebi Francophone author Mahi Binebine revisits the encounter between the so-called “cannibals” and the European colonizer in the context of illegal immigration where bodies become commodities exchangeable for social improvements creating a different form of cannibalism. It is no longer the usual dichotomy between the civilized and the savage that is at work but rather a “civilized” European imperialist who feeds himself on a migrant’s flesh. This article argues that this representation works as a “colonial fragment” from the past but contextualized in today’s globalization. Binebine’s morbid depiction of an ambivalent postcolonial cannibalistic encounter translates as a representation of migrants in terms of cannibalistic necropolitics. The illegal migrant has no choice but to be swallowed by a narcissistic exocannibalism which seeks to incorporate what it feeds on to a total unity suggesting a bleak future not only for illegal migrants but for globalization as possibly devouring itself
SLOTTING ALLOWANCES: EMPIRICAL EVIDENCE ON THEIR ROLE IN NEW PRODUCT LAUNCHES
No full textThe retail practice of charging a fee to stock new products is a relatively new but growing phenomenon. Termed a "slotting allowance", it has attracted considerable scrutiny because of uncertainty about its purposes and consequences. We propose and statistically test several hypotheses to assess the degree of empirical support for each of several extant explanations. Slotting allowances, we find, are charged by relatively large retailers who have an informational advantage over the manufacturer about the likely success of the new product. This result apparently contradicts theorizing about the "informational" content of slotting fees, as well as other pro- and anti-competitive explanations. We also find support for the claim that when retailers fear that manufacturers will not provide post-launch support, they pay relatively high wholesale prices.Industrial Organization, Marketing,
THE PRICE OF LAUNCHING A NEW PRODUCT: EMPIRICAL EVIDENCE ON FACTORS AFFECTING THE RELATIVE MAGNITUDE OF SLOTTING ALLOWANCES
No full textSlotting allowances are a relatively recent trend, particular to the retail food industry. These allowances are lump-sum up-front transfer payments from manufacturer to retailer when the manufacturer launches a new product. The practice has attracted some scrutiny because of uncertainty about its purposes and consequences. We draw from the extant literature to identify factors that potentially influence the relative magnitude of slotting allowances. Based on analysis of primary survey data from retailers and manufacturers, we observe that the charging and paying of slotting allowances is seemingly affected by the relative strength of the players. Among retailers, the relative magnitude of slotting fees increases with retailers' informational advantage over the manufacturer about the likely success of the new product. Similarly, the relative magnitude of slotting fees paid is lower for manufacturers who have a strong market share position. We discuss the theoretical, managerial and public policy implications of our findings

Among retailers, the relative magnitude of slotting fees increases with retailers' informational advantage over the manufacturer about the likely success of the new product, even when retailers recognize that the product is likely to be successful. Additionally, and consistent with the first finding, retailers with lower costs (i.e., potentially more efficient and powerful retailers) received higher slotting allowances. Furthermore, retailers charge higher slotting fees, even when concerns about manufacturers' fulfilling postlaunch advertising commitments are minimal, implying that relatively powerless manufacturers are asked to provide credible commitments regarding postlaunch activitiesare asked to pay relatively high slotting fees. Among manufacturers, the relative magnitude of slotting fees paid is lower for those who have a strong market share position. We discuss the theoretical, managerial, and public policy implications of our findings.Slotting Allowances, Information Asymmetry, New Product Introductions, Retail Food Industry

Oranga whānau, oranga niho: The oral health status of 5-year-old Māori children. A case study
No full textResearch has shown that the oral health of Māori is far worse than non-Māori across all
age groups. The objective of this research study was to assess the dental wellbeing of
5-year olds with a specific focus on Māori children currently residing in the Hamilton City
region. In addition, this research focused on the impact that social, economic, cultural
and environmental factors have on oral health. A total of 32 participants were invited to
take part in this research: 15 5-year-old children from three selected schools, 15 (of the
children's) caregivers and 2 dental therapists who work in the Hamilton City region.
The findings indicated that overall Māori children and children of lower socio-economic
status had a much higher prevalence of dental caries (tooth decay) than non-Māori
children and children of higher socio-economic status. A number of contributing factors
were shown to be responsible for this disparity including the cultural inappropriateness
of oral health services and resources, affordability, role-modelling, parental awareness
and education, and the transient nature of families.
It was found that no one strategy or intervention will achieve dramatic improvements in
Māori oral health as a concerted effort is required by Local and Central Government, the
Health Sector and Māori communities
