Being tough doesn’t always pay off: The culture of honor vs dignity in negotiation
Early work on cross-cultural negotiation has focused on East-West differences. In the current study we investigate the negotiation scripts employed by Middle Eastern negotiators, more specifically Iranian negotiators, in an intracultural interaction, compared to North American negotiators. We examine how the Iranian worldviews, beliefs, norms, and social behavior influence their goals and aspirations, negotiation tactics, and ultimately final outcome. We formulated our hypotheses based on the theory of honor-dignity cultures and illustrate how the importance of preserving and maintaining honor influences the Iranian negotiation strategies in business dealings. Our results illustrate that consistent with the culture of honor, Iranian negotiators are more likely to be competitive, express emotions, and employ distributive tactics compared to Canadian negotiators. Moreover, this competitive mindset leaves Iranian negotiators at a disadvantage as the overall joint gain is significantly lower than Canadian negotiators
Behavioral Mimicry in Chinese and Canadian Negotiations: Frequency, Duration and Impact
Negotiation literature stresses the importance of mimicry in improving relational and economic outcomes. Yet, there is a dearth of work examining how culture influences the display and impact of mimicry in negotiations. In this research, we systematically coded behavioral mimicry among Chinese and Canadian dyadic, intracultural, video-taped negotiations. Using cultural theories of high/low context communication, and individualism/collectivism, we predicted and found that low-context, individualistic Canadian negotiators were more direct in their behavioral mimicry by exhibiting higher frequency of postural mimicry, than Chinese negotiators. In contrast, Chinese negotiators were more indirect in their displays of mimicry via longer durations of mirrored postures. Interestingly, gender moderated the effects of culture on the frequency and duration of mimicry. Mimicry led to higher joint gains, only when dyads did not attend to the indirect meanings of the mimicked behaviors. We discuss implications of behavioral mimicry in cross-cultural negotiations
The Utility of Amnioinfusion in the Prophylaxis of Meconium-Stained Amniotic Fluid Infectious Morbidity
Objectives: To evaluate the utility of intrapartum amnioinfusion (AI) in reducing the infectious morbidity of patients with meconium-stained fluid (MSF). Previous studies have shown increased intraamniotic infection (IAI) and postpartum endometritis (PPE) rates in patients with MSF. Intraamniotic infection has been reduced with the prophylactic administration of ampicillin–sulbactam in MSF. Intraamniotic infection and PPE have been reduced with the use of AI in patients with clear fluid. No investigators have specifically examined the efficacy of AI in reducing meconium-stained, amniotic-fluid-associated infectious morbidity
Multivariate Hierarchical Modelling of Household Air Pollution
This is the author accepted manuscript. The final version is available from the Statistical Modelling Society via the link in this recordExposure to household air pollution has been attributed to an estimated 3.8 million deaths per year. A major contributor to this exposure is the reliance on various polluting fuels for cooking by almost half of all households in low and middle-income countries. We present a multivariate hierarchical model for surveys of the proportion of people relying on each fuel type, for the period 1990-2017, addressing several challenges with modelling the data including incomplete surveys and sampling bias.Natural Environment Research Council (NERC)World Health Organizatio
A new model for magnetoreception
Certain migratory birds can sense the earth's magnetic field. The nature of
this process is not yet properly understood. Here we offer a simple explanation
according to which birds literally `see' the local magnetic field: Our model
relates the well-established radical pair hypothesis to the phenomenon of
Haidinger's brush, a capacity to see the polarisation of light. This new
picture explains recent surprising experimental data indicating long lifetimes
for the radical pair. Moreover there is a clear evolutionary path toward this
field sensing mechanism: it is an enhancement of a weak effect that may be
present in many species.Comment: 8 pages, 5 figures, version of final published pape
Household cooking fuel estimates at global and country level for 1990 to 2030
Household air pollution generated from the use of polluting cooking fuels and technologies is a major source of disease and environmental degradation in low- and middle-income countries. Using a novel modelling approach, we provide detailed global, regional and country estimates of the percentages and populations mainly using 6 fuel categories (electricity, gaseous fuels, kerosene, biomass, charcoal, coal) and overall polluting/clean fuel use – from 1990-2020 and with urban/rural disaggregation. Here we show that 53% of the global population mainly used polluting cooking fuels in 1990, dropping to 36% in 2020. In urban areas, gaseous fuels currently dominate, with a growing reliance on electricity; in rural populations, high levels of biomass use persist alongside increasing use of gaseous fuels. Future projections of observed trends suggest 31% will still mainly use polluting fuels in 2030, including over 1 billion people in Sub-Saharan African by 2025
Sexual reproduction and two different encystment strategies of Lingulodinium polyedrum (Dinophyceae) in culture
Unreported aspects in the sexual cycle of the marine dinoflagellate Lingulodinium polyedrum (Stein) Dodge were described. Our observations included the description of two types of hypnozygote formation, because culture planozygotes were observed to encyst in two different ways: an ecdysal sexual stage or a spiny resting cyst. Phosphate deficiency was the main nutritional condition required for fusing gamete pairs to form resting cysts, whereas replete conditions prevented their appearance and favored the formation of ecdysal sexual forms. Mating experiments revealed the existence of two sexual types (+/−), which were enough to explain resting cyst appearance (simple heterothallism). Morphological aspects and timing of gamete mating, fusion, and the efficiency of encystment under different external levels of nitrate and phosphate were analyzed after isolating and monitoring individual pairs of fusing gametes. The staining of sexual stages showed that nuclear fusion was completed at the same time as the cytoplasmic fusion. After 1 to 2 h, the planozygotes presented one quadrolobulated nucleus. Germination of ecdysal sexual stages occurred after <24–72 h, whereas excystment of resting cysts was dependent on the studied parental cross and took place after 2–4 months. Newly germinated cells from both types of cysts had a similar, big, U-shaped nucleus. Twenty-four to 48 h after excystment, the germlings divided by desmoschisis, a process before which enlargement of the nucleus was observed.Postprin
Global household energy model: a multivariate hierarchical approach to estimating trends in the use of polluting and clean fuels for cooking
This is the final version. Available on open access from Wiley via the DOI in this recordIn 2017 an estimated 3 billion people used polluting fuels and technologies as their primary cooking solution, with 3.8 million deaths annually attributed to household exposure to the resulting fine particulate matter air pollution. Currently, health burdens are calculated using aggregations of fuel types, e.g. solid fuels, as country-level estimates of the use of specific fuel types, e.g. wood and charcoal, are unavailable. To expand the knowledge base about impacts of household air pollution on health, we develop and implement a Bayesian hierarchical model, based on Generalized Dirichlet Multinomial distributions, that jointly estimates non-linear trends in the use of eight key fuel types, overcoming several data-specific challenges including missing or combined fuel use values. We assess model fit using within-sample predictive analysis and an out-of-sample prediction experiment to evaluate the model's forecasting performance.Natural Environment Research Council (NERC)World Health Organizatio
Endocrine disruptors and abnormalities of pubertal development
Onset and development of puberty is regulated by the neuroendocrine system. Population-based studies worldwide have observed secular trends towards earlier puberty development. These changes are apparently caused by environmental factors such as improved socio-economic status, improved health care and nutrition. However, they may also partly result from endocrine-disrupting chemicals in the environment. Epidemiological studies have investigated the relationship between pubertal development and exposure to endocrine-disrupting chemicals (polychlorinated biphenyls, polybrominated biphenyls, 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane, phthalate esters, furans and the pesticide endosulfan). Associations with both perinatal and postnatal exposure have been reported. Studies in experimental animals support some of these findings and point to differential endocrine regulatory mechanisms linked to pubertal development acting in the perinatal and the pre-pubertal period. Pubertal development is naturally associated with growth and body composition. There is increasing evidence for a link between prenatal development and pubertal onset. In girls born small for gestational age (SGA), pubertal onset and age at menarche often are advanced, especially if there has been an extensive catch-up growth during the first months of life. In utero growth retardation may have multiple causes including exposure to xenobiotic substances as was suggested for some endocrine-disrupting chemicals. An abnormal perinatal environment of children born SGA may alter the endocrine status and the sensitivity of the receptors for endocrine and metabolic signalling that may have effects on maturation of brain and gonads. However, the causal pathways and the molecular mechanisms that may link the pubertal growth pattern of children born SGA, pubertal development and endocrine-disrupting chemicals need further study
Who stops the sweatshops? Our neglect of the injustice of maldistribution
Researchers have attempted to hold fashion, beauty and toy industries’ promotion of narrow beauty ideals responsible for the injustice of body dissatisfaction. We advocate for reform by calling upon the industries to represent plus-sized and older models (e.g., on catwalks) as antidotes to narrow beauty ideals; citing evidence that the use of such models are no less profitable. This attempts to address what Fraser (1995) calls the injustice of misrecognition. This advocacy however not only masks another injustice these industries perpetuate: maldistribution (Fraser, 1995), but it can actively worsen it. This is most poignantly exemplified by the 250 million sweatshop workers in the Global South working in these industries. Those of us advocating against these industries’ injustices, are encouraged to join People and Planet in their campaign to use universities’ vast purchasing power for sweatshop reform. This is one small way to advocate against maldistribution, redressing the imbalance
