Drought, Domestic Budgeting and Wealth Distribution in Sahelian Households

DEVELOPMENT AND CHANGE, Issue 5 2000
Matthew Turner
Over the past twenty-five years, Sahelian households have experienced recurrent harvest failure and greater reliance on remittances from migratory wage labour. Household subsistence has become less dependent on household grain stores and more on the liquidation of individual wealth stores. This study investigates how these broader changes have affected struggles between household members over obligations to support the household in the Zarmaganda region of western Niger. As the land-derived leverage of male patriarchs has declined and household dependence on individual wealth stores has increased, domestic budgeting has become more contested. Household heads make case-by-case moral claims on other household members during times of grain shortage. Women and subordinate males invoke Islamic law, which accords primary provisioning responsibility to the household head, to protect their individual wealth in times of grain deficit. This article investigates the nature of these budgetary struggles, showing how individuals' decisions to contribute individual wealth to support the household are best understood as highly situated, affected not only by the specific material conditions of the household but also the interplay of the moral, structural, and individualistic imperatives that derive from one's position within the household. Using reconstructed livestock wealth histories for the members of fifty-four households in western Niger, this study investigates the material consequences of these struggles. Male heads of corporate households, the historic managers of the household's land and agricultural labour, have lost wealth relative to their wives and married male subordinates since the drought of 1984.

The cranial morphology of Kayentachelys, an Early Jurassic cryptodire, and the early history of turtles

ACTA ZOOLOGICA, Issue 3 2010
Eugene S. Gaffney
Abstract Gaffney, E.S. and Jenkins, F.A., Jr. 2010. The cranial morphology of Kayentachelys, an Early Jurassic cryptodire, and the early history of turtles. , Acta Zoologica (Stockholm) 91: 335,368 The skull morphology of Kayentachelys aprixGaffney et al., 1987, a turtle from the Early Jurassic Kayenta Fm of northern Arizona, demonstrates the presence of cryptodiran synapomorphies in agreement with Gaffney et al. (1987, 1991, 2007), and contrary to the conclusions of Sterli and Joyce (2007), Joyce (2007), Sterli (2008), and Anquetin et al. (2008). Specific characters found in Kayentachelys and diagnostic of cryptodires include the processus trochlearis oticum, the curved processus pterygoideus externus with a vertical plate, and the prefrontal,vomer contact, which are confirmed as absent in the outgroups, specifically the Late Triassic Proganochelys. The Joyce (2007) analysis suffers from the reduction of the signal from skull characters, with a consequently greater reliance on shell characters, resulting in pleurodires being resolved at various positions within the cryptodires. Kayentachelys reveals what a primitive cryptodire would be expected to look like: a combination of primitive and derived characters, with the fewer derived characters providing the best test of its relationships to other turtles. Although incompletely known, the Mid-Late Jurassic Condorchelys, Heckeremys, and Eileanchelys may be early cryptodires close to Kayentachelys. We confirm the Late Triassic Proterochersis as a pleurodire, dating the pleurodire,cryptodire split as Late Triassic or earlier. [source]


Investigating the Incidence of type i errors for chronic whole effluent toxicity testing using Ceriodaphnia dubia

ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 1 2000
Timothy F. Moore
Abstract The risk of Type I error (false positives) is thought to be controlled directly by the selection of a critical p value for conducting statistical analyses. The critical value for whole effluent toxicity (WET) tests is routinely set to 0.05, thereby establishing a 95% confidence level about the statistical inferences. In order to estimate the incidence of Type I errors in chronic WET testing, a method blank-type study was performed. A number of municipal wastewater dischargers contracted 16 laboratories to conduct chronic WET tests using the standard test organism Ceriodaphnia dubia. Unbeknownst to the laboratories, the samples they received from the wastewater dischargers were comprised only of moderately hard water, using the U.S. Environmental Protection Agency's standard dilution water formula. Because there was functionally no difference between the sample water and the laboratory control/dilution water, the test results were expected to be less than or equal to 1 TUc (toxic unit). Of the 16 tests completed by the biomonitoring laboratories, two did not meet control performance criteria. Six of the remaining 14 valid tests (43%) indicated toxicity (TUc > 1) in the sample (i.e., no-observed-effect concentration or IC25 < 100%). This incidence of false positives was six times higher than expected when the critical value was set to 0.05. No plausible causes for this discrepancy were found. Various alternatives for reducing the rate of Type I errors are recommended, including greater reliance on survival endpoints and use of additional test acceptance criteria. [source]


Organic phosphorus speciation and pedogenesis: analysis by solution 31P nuclear magnetic resonance spectroscopy

EUROPEAN JOURNAL OF SOIL SCIENCE, Issue 6 2007
R. W. McDowell
Summary Changes in phosphorus (P) during soil development are central to the understanding of labile P for plant productivity and soil P management. We used NaOH-EDTA extraction with 31P nuclear magnetic resonance spectroscopy (31P NMR), sequential P fractionation, and general soil chemical characterization to better our understanding of P dynamics within two chronosequences (Manawatu and Reefton) and one Basalt maturity sequence under original native vegetation. With time, orthophosphate and orthophosphate monoesters tended to increase with organic C to a maximum of about two-thirds of NaOH-EDTA-extractable P in young soils (16 000 years in the Reefton chronosequence), but gradually declined thereafter to about one-third of NaOH-EDTA-extractable P in the oldest soils (130 000 years old). This coincided with a depletion of P from primary minerals (e.g. apatite) and readily available P for plant production. This depletion of inorganic P resulted in a greater reliance on organic P cycling via mineralization, hence the depletion of the normally recalcitrant monoester-P pool. Concomitantly, the build-up of labile P species (diesters and pyrophosphate) and scyllo - over myo -inositol hexakisphosphate occurred as soils developed, and might be attributed to microbial activity, including scavenging for P. This work highlights the importance of organic P cycling during pedogenesis. [source]


BREAKING DOWN BUSINESS VALUATION: THE USE OF COURT-APPOINTED BUSINESS APPRAISERS IN DIVORCE ACTIONS*

FAMILY COURT REVIEW, Issue 4 2006
Donna TumminioArticle first published online: 11 SEP 200
This Note advocates for greater reliance on court-appointed business appraisers in divorce proceedings. After exploring the history of court-appointed experts in American jurisprudence and addressing the specific problems that arise when valuing a business, this Note demonstrates how neutral business appraisers can assist courts in assessing a highly technical matter while simultaneously providing both courts and parties with an accurate, reliable source of information. The Note further provides suggestions for when the appointment of a neutral appraiser may be beneficial. The second section of this Note addresses technical matters that the court must deal with in selecting a reliable expert, including where the court derives its power to appoint a neutral expert, what standards the court should use in appointing the expert, and who should pay the cost of the expert's appointment.

Reach-scale geomorphology affects organic matter and consumer ,13C in a forested Piedmont stream

FRESHWATER BIOLOGY, Issue 6 2007
D. M. WALTERS
Summary 1. We investigated the spatial (longitudinal position and reach geomorphology) and seasonal (spring and autumn) influences on the variation of ,13C among organic matter sources and consumers in a forested Piedmont river, South Carolina, U.S.A. 2. Six sites were sampled along a continuum and varied in basin area from approximately 30 to 300 km2. Sites fell into two geomorphic categories (i) high-gradient, rock bed (,rock') or (ii) low-gradient, sand bed (,sand') sites. 3. Variation in ,13C was more strongly related to reach geomorphology than longitudinal position. ,13C of biofilm and consumers was consistently enriched at rock sites. Leaf litter (i.e. coarse particulate organic matter, CPOM) ,13C did not vary with bed type. There was significant ,13C enrichment at rock sites for biofilm, seston, fine benthic organic matter (FBOM), and eight of nine consumer trophic guilds (e.g. grazing invertebrates, insectivorous fishes). ,13C of biofilm and four trophic guilds was also positively correlated with drainage area, but the magnitude of enrichment was less than between bed types. 4. ,13C was generally enriched in spring, but this varied among organic matter types, consumers, and by bed type. CPOM and seston were enriched in spring, FBOM was enriched in autumn, and biofilm showed no trend. Five consumer guilds were enriched in spring, and only one fish guild, generalised carnivores, showed enrichment of muscle tissue in autumn. 5. Consumer ,13C enrichment at rock sites suggests greater reliance on algal carbon than for consumers at sand sites, but we also found ,13C enrichment of biofilm at rock sites. Thus, differences in consumer ,13C between bed types could be related to (i) increased consumption of biofilm at rock compared with sand sites, or (ii) consumption of biofilm at rock sites that is enriched relative to biofilm at sand sites or (iii) both mechanisms. 6. ,13C signatures in local food webs appear to respond to processes operating at multiple spatial scales. Overall downstream enrichment of biofilm and consumers was disrupted by strong local effects related to bed morphology. These results suggest that human alteration of channel habitat will have corresponding effects on stream food webs, as assessed by changes in ,13C. [source]


Do uninformed crossed and internalized trades tap into unexpressed liquidity?

ACCOUNTING & FINANCE, Issue 2 2009
The case of Nokia
G10; G15; G24 Abstract Crossed and internalized upstairs trades are analysed in a dataset in which institutional investors can be identified. Earlier findings that upstairs trading is uninformed, taps into unexpressed liquidity, and does not affect market quality are revisited. The permanent price effect of crossings and internalized upstairs trades is significantly lower than that of limit order book trades due to the fact that the least informed institutional trades are routed upstairs. Crossed and internalized trades affect the depth and transaction costs in the limit order book and a greater reliance is placed on the upstairs market when liquidity is low and volatility is high.

The Cat and Mouse Game at the Mexico-U.S. Border: Gendered Patterns and Recent Shifts1

INTERNATIONAL MIGRATION REVIEW, Issue 2 2008
Katharine M. Donato
This paper provides new insights into the process of undocumented border crossing by examining both men and women in the process. We investigate differences in the ways in which men and women make their way across the well-guarded Mexico-U.S. border, and the extent to which men and women by the end of the 1990s were similar to, or different from, their counterparts who crossed before 1986 and the implementation of immigration policy designed to reduce undocumented migration. We find substantial differences in how men and women crossed the border without legal documents and in their chances of being apprehended. Our analysis makes clear that shifts in U.S. immigration policy after 1986 have led to women's greater reliance on the assistance of paid smugglers to cross without documents but men were more likely to cross alone. Moreover, immediately after 1986, women on first U.S. trips faced higher risks of being apprehended compared to women who migrated in the early 1980s, but men faced lower risks. After accumulating some U.S. experience, however, both women and men faced lower risks of being detected after 1986 compared to earlier in that decade. [source]


Variation in Heat-shock Proteins and Photosynthetic Thermotolerance among Natural Populations of Chenopodium album L. from Contrasting Thermal Environments: Implications for Plant Responses to Global Warming

JOURNAL OF INTEGRATIVE PLANT BIOLOGY, Issue 11 2008
Deepak Barua
Abstract Production of heat-shock proteins (Hsps) is a key adaptation to acute heat stress and will be important in determining plant responses to climate change. Further, intraspecifc variation in Hsps, which will influence species-level response to global warming, has rarely been examined in naturally occurring plants. To understand intraspecific variation in plant Hsps and its relevance to global warming, we examined Hsp content and thermotolerance in five naturally occurring populations of Chenopodium album L. from contrasting thermal environments grown at low and high temperatures. As expected, Hsp accumulation varied between populations, but this was related more to habitat variability than to mean temperature. Unexpectedly, Hsp accumulation decreased with increasing variability of habitat temperatures. Hsp accumulation also decreased with increased experimental growth temperatures. Physiological thermotolerance was partitioned into basal and induced components. As with Hsps, induced thermotolerance decreased with increasing temperature variability. Thus, populations native to the more stressful habitats, or grown at higher temperatures, had lower Hsp levels and induced thermotolerance, suggesting a greater reliance on basal mechanisms for thermotolerance. These results suggest that future global climate change will differentially impact ecotypes within species, possibly by selecting for increased basal versus inducible thermotolerance. [source]


European Manifesto on Basic Standards of Health Care For People with Intellectual Disabilities

JOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 1 2004
M. M. Meijer
Abstract An invitational conference organized by the Netherlands Society of Physicians for Persons with Intellectual Disabilities (NVAVG) and the European Association of Intellectual Disability Medicine (MAMH), in collaboration with the Erasmus Medical Center's Department of Specialist Training for Physicians for People with Intellectual Disabilities, had as its aim the development and issuance of an European manifesto on adequate health care for people with intellectual disabilities (ID). This paper provides an overview of the basis for the conference and the manifesto and lays out recommendations for the implementation of the manifesto's main points. The group's product, the European Manifesto on Basic Standards of Health Care for People with Intellectual Disabilities, summarizes the core elements of adequate health care for individuals with ID, and offers guidance on how Europe's nations may address deficiencies in health provision for people with ID. The manifesto's main points include a call for greater available and accessible health care, increasing the competencies in ID of health professionals, educators, and researchers, a greater reliance on a multidisciplinary approach to health care, more specialist services, and a proactive emphasis on personal health management.

Foraging and ranging behavior during a fallback episode: Hylobates albibarbis and Pongo pygmaeus wurmbii compared

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 4 2009
Erin R. Vogel
Abstract Periodic episodes of food scarcity may highlight the adaptive value of certain anatomical traits, particularly those that facilitate the acquisition and digestion of exigent fallback foods. To better understand the selective pressures that favored the distinctive dental and locomotor morphologies of gibbons and orangutans, we examined the foraging and ranging behavior of sympatric Hylobates albibarbis and Pongo pygmaeus wurmbii during an episode of low fruit availability at Tuanan, Kalimantan Tengah, Indonesia. We found that Hylobates ranged 0.5 km day,1 or 33% farther than did Pongo, but the overall daily ranging of both species did not vary as fruit availability decreased by as much as 50%. Among gibbons, we observed dietary switching to fallback foods; in particular, there was a progressively greater reliance on figs, liana products, and unripe fruit. Orangutans relied heavily on unripe fruit and fracture-resistant bark and pith tissues. Despite these divergent fallback patterns, the stiffness of fruit mesocarp consumed by Hylobates and Pongo did not differ. We discuss canine and molar functional morphology with respect to dietary mechanics. Next, to contextualize these results, we discuss our findings with respect to forest structure. The rain forests of Southeast Asia have been described as having open, discontinuous canopies. Such a structure may inform our understanding of the ranging behavior and distinctive locomotion of apes in the region, namely richochetal brachiation and quadrumanous clambering. Our approach of integrating behavioral ecology with physical measures of food may be a powerful tool for understanding the functional adaptations of primates.

Internal vs. external learning in new product development: effects on speed, costs and competitive advantage

R & D MANAGEMENT, Issue 3 2000
Eric H. Kessler
The purpose of this study was to investigate how different technology sourcing strategies throughout the new product development process influenced innovation speed, development costs, and competitive advantage. We studied 75 new product development projects from ten large, U.S.-based companies in several industries. Results indicated that: (1) more external sourcing during the early (i.e., idea generation) stage was related with lower competitive success; (2) more external sourcing during the later (i.e., technological development stage was related with slower innovation speed; and (3) development costs tended to rise with greater reliance on external sources of technology, but this result was not statistically significant.

Audiovisual Speech Perception in Elderly Cochlear Implant Recipients,

THE LARYNGOSCOPE, Issue 10 2005
Marcia J. Hay-McCutcheon PhD
Abstract Objectives/Hypothesis: This study examined the speech perception skills of a younger and older group of cochlear implant recipients to determine the benefit that auditory and visual information provides for speech understanding. Study Design: Retrospective review. Methods: Pre- and postimplantation speech perception scores from the Consonant-Nucleus-Consonant (CNC), the Hearing In Noise sentence Test (HINT), and the City University of New York (CUNY) tests were analyzed for 34 postlingually deafened adult cochlear implant recipients. Half were elderly (i.e., >65 y old) and other half were middle aged (i.e., 39,53 y old). The CNC and HINT tests were administered using auditory-only presentation; the CUNY test was administered using auditory-only, vision-only, and audiovisual presentation conditions Results: No differences were observed between the two age groups on the CNC and HINT tests. For a subset of individuals tested with the CUNY sentences, we found that the preimplantation speechreading scores of the younger group correlated negatively with auditory-only postimplant performance. Additionally, older individuals demonstrated a greater reliance on the integration of auditory and visual information to understand sentences than did the younger group Conclusions: On average, the auditory-only speech perception performance of older cochlear implant recipients was similar to the performance of younger adults. However, variability in speech perception abilities was observed within and between both age groups. Differences in speechreading skills between the younger and older individuals suggest that visual speech information is processed in a different manner for elderly individuals than it is for younger adult cochlear implant recipients.

The Use of Performance-based Remuneration: High versus Low-growth Firms

AUSTRALIAN ACCOUNTING REVIEW, Issue 3 2010
Julie Walker
This study analyses the CEO remuneration structure and level for 100 Australian-listed entities. Consistent with expectations, it finds that high-growth firms pay their CEOs a greater proportion of performance-based pay, when equity-based rewards only are considered. High-growth firms also place greater reliance on market and/or non-financial performance standards for the award of performance-based pay. The extent to which performance-based remuneration is used as a component of CEO pay is positively associated with firm size and growth options. Other potential determinants of performance-based pay, such as financial performance, are not significantly associated with the use of performance-based remuneration. [source]


Microeconometric analysis of wine grape supply contracts in Australia,

AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 1 2005
Iain Fraser
This paper examines wine grape supply contracts used in the main grape growing regions of Australia. An empirical analysis provides insight into specific aspects of contract design and implementation. Statistical analyses of sample data reveal differences between regions in contract specifications. Lower quality grape growing regions place a greater reliance on grape quality assessment to determine bonus/penalty payments compared to higher quality regions. Contracts in higher quality regions place greater emphasis on explicit winery involvement and direction in vineyard management. Results indicate that longer duration contracts are more inclusive in terms of the number of clauses included. Evidence of risk shifting (i.e., winery to grower) for high quality grapes is reported, where the price received by growers is determined by the bottle price of the wine produced. [source]


The Origins of the British Commonwealth Strategic Reserve: The UK Proposal to Revitalise ANZAM and the increased Australian Defence Commitment to Malaya

AUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 4 2004
Hiroyuki Umetsu
At the end of 1952 the UK proposed to revitalise the ANZAM arrangement by concentrating it more closely on the defence of British interests in Malaya. Hitherto ANZAM had focused almost completely upon planning for the wartime defence of sea communications in the Southwest Pacific. This article explains why the UK sought to revitalise ANZAM, and why Australia accepted the British proposal. The British proposal arose from the adoption by the UK of a strategy of nuclear deterrence which led it to project both a future reduction of British conventional forces available for overseas commitments, and a greater reliance upon Commonwealth partners for the protection of British interests in Malaya. It also represented an attempt to reduce the value of the ANZUS security treaty, signed in early September 1951. Australia accepted the British proposal that Commonwealth partners should shoulder a heavier burden in Malaya as a way of preserving the value of ANZUS and of adjusting to the future reduction of the British military presence in Asia.

Adaptations Of Skeletal Muscle To Prolonged, Intense Endurance Training

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 3 2002
John A Hawley
SUMMARY 1. Endurance exercise induces a variety of metabolic and morphological responses/adaptations in skeletal muscle that function to minimize cellular disturbances during subsequent training sessions. 2. Chronic adaptations in skeletal muscle are likely to be the result of the cumulative effect of repeated bouts of exercise, with the initial signalling responses leading to such adaptations occurring after each training session. 3. Recently, activation of the mitogen-activated protein kinase signalling cascade has been proposed as a possible mechanism involved in the regulation of many of the exercise-induced adaptations in skeletal muscle. 4. The protein targets of AMP-activated protein kinase also appear to be involved in both the regulation of acute metabolic responses and chronic adaptations to exercise. 5. Endurance training is associated with an increase in the activities of key enzymes of the mitochondrial electron transport chain and a concomitant increase in mitochondrial protein concentration. These morphological changes, along with increased capillary supply, result in a shift in trained muscle to a greater reliance on fat as a fuel with a concomitant reduction in glycolytic flux and tighter control of acid,base status. Taken collectively, these adaptations result in an enhanced performance capacity. [source]


Working with older people: implications for schema theory

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 3 2003
Ian A. James
Working with older people requires therapists to examine issues regarding information processing often not dealt with by therapists working with younger patients. It is suggested that these processing issues may be especially salient to therapists working with older people, owing to their greater reliance on their theoretical knowledge of memory (declarative, procedural, working etc.) and neuropsychology. The present paper draws on this more holistic background, and presents a theory designed to facilitate therapy in general: particularly schema focused therapy for both the young and old. Employing knowledge and models routinely used in an older people's setting, this paper redefines schemata in terms of networks of information and memories rather than viewing them solely as self-referent beliefs (e.g. I am worthless; I am inadequate). This change in perspective allows us to see schemata more validly as elaborate structures, composed of many elements, including behavioural, emotional and visceral features. A rationale in support of this holistic perspective is outlined, together with a review of its implications in terms of schema assessment and change techniques.
