TY - JOUR. T1 - Expression profiles during honeybee caste determination.. AU - Evans, J. D.. AU - Wheeler, D. E.. PY - 2001. Y1 - 2001. N2 - BACKGROUND: Depending on their larval environment, female honeybees develop into either queens or workers. As in other polyphenisms, this developmental switch depends not on genomic differences between queens and workers but on the differential expression of entire suites of genes involved with larval fate. As such, this and other polyphenic systems can provide a novel tool for understanding how genomes and environmental conditions interact to produce different developmental trajectories. Here we use gene-expression profiles during honeybee caste determination to present the first genomic view of polyphenic development. RESULTS: Larvae raised as queens or workers differed greatly in their gene-expression patterns. Workers remained more faithful than queens to the expression profiles of younger, bipotential, larvae. Queens appeared to both downregulate many ...
When you start a new job, its normal to spend the first day working out whos who in the pecking order, information that will come in handy for making connections in the future. In an fMRI study published in Neuron, researchers at DeepMind and UCL provide insights into how we acquire knowledge about social hierarchies, and reveal the specific mechanisms at play when that hierarchy is our own (as compared to that of another person).
The period of Anglo-Saxon Warfare spans the 5th Century AD to the 11th in England. Its technology and tactics resemble those of other European cultural areas of the Early Middle Ages, although the Anglo-Saxons, unlike the Continental Germanic tribes such as the Franks and the Goths, do not appear to have regularly fought on horseback. Although much archaeological evidence for Anglo-Saxon weaponry exists from the Early Anglo-Saxon period due to the widespread inclusion of weapons as grave goods in inhumation burials, scholarly knowledge of warfare itself relies far more on the literary evidence, which was only being produced in the Christian context of the Late Anglo-Saxon period. These literary sources are almost all authored by Christian clergy, and thus do not deal specifically with warfare; for instance, Bedes Ecclesiastical History of the English People mentions various battles that had taken place but does not dwell on them. Thus, scholars have often drawn from the literary sources from ...

Toy preference and associated gross and fine motor movements of preschool orthopedically handicapped children were evaluated in a free-play situation. Fifteen children between 3 and 5 years of age and representing two separate classes served as subjects. The study was conducted for 7 weeks in the subjects classroom. Sessions were scheduled 2 times per week in each class, each lasting 1 hour. Twenty toys were evaluated using a modified version of the procedure developed by the University of Kansas Living Environments Group. Measurement of movement behavior associated with toy play involved application of a movement glossary developed by the experimenter. A Wilcoxon two-sample rank test revealed no significant differences for either gender, age, or ambulation (ambulatory versus nonambulatory) in relation to toy preference or nature of movement demonstrated. Analysis revealed that subjects spent considerable time using toys in a manner which did not correspond to their design. It was recommended ...
Sex differences in toy preferences in children are marked, with boys expressing stronger and more rigid toy preferences than girls, whose preferences are more flexible. Socialization processes, parents, or peers encouraging play with gender-specific toys are thought to be the primary force shaping s …
From figure 1 it can be seen that under a range of plausible combinations of selective advantage to being Anglo-Saxon and intermarriage rate (see below), the proportion of immigrant Y-chromosomes rises from 20% or less immediately following migration to greater than 50% in 15 generations. We consider 50% to be a conservative estimate of the proportion of Y-chromosomes in the present-day English gene pool that originate among Anglo-Saxon migrants in the fifth century (Weale et al. 2002; Capelli et al. 2003). Fifteen generations marks the upper limit for the duration of an Anglo-Saxon/British apartheid-like social structure since, by assuming an intergenerational time of between 25 and 30 years, this is the approximate time span between the initial immigration in the middle of the fifth century and the laws of Alfred the Great (issued around AD 890), which do not contain any indications of legal status differences between Britons and Anglo-Saxons (Whitelock 1979). Although others have reported a ...
Social hierarchy formation is strongly evolutionarily conserved. Across species, rank within social hierarchy has large effects on health and behavior. To investigate the relationship between social rank and stress susceptibility, we exposed ranked male and female mice to social and non-social stressors and manipulated social hierarchy position. We found that rank predicts same sex social stress outcomes: dominance in males and females confers resilience while subordination confers susceptibility. Pre-existing rank does not predict non-social stress outcomes in females and weakly does so in males, but rank emerging under stress conditions reveals social interaction deficits in male and female subordinates. Both history of winning and rank of cage mates affect stress susceptibility in males: rising to the top rank through high mobility confers resilience and mice that lose dominance lose stress resilience, though gaining dominance over a subordinate animal does not confer resilience. Overall, we ...

Simply being at the bottom of the social heap directly alters the body, BBC News reports. The headline is based on a study in which researchers used female monkeys to simulate social hierarchies.. Monkeys of low social status were found to have biomarkers indicating poor immune function and possible increased vulnerability to infection.. The researchers arranged the monkeys into social groups and observed behaviours for two years to determine the social hierarchy. They then mixed-up the groups so that some of the monkeys were introduced into other groups as the new girl. This effectively meant that the newbie monkey was stripped of all social status.. They then took blood samples to look at any effect this had on the immune system. The study found that social rankings in the monkey groups had an effect on white blood cells involved in fighting off disease. These findings suggested that the stress of a lower social ranking may increase inflammation and reduce resistance to infection and ...
Social hierarchy exists in almost all social species and affects everything from resource allocation to the development of intelligence. Previous studies showed that status within a social hierarchy influences the perceived fairness of income allocation. However, the effect of ones social status on economic decisions is far from clear, as are the neural processes underlying these decisions. In this study, we dynamically manipulated participants social status and analyzed their behavior as recipients in the ultimatum game, during which event-related potentials (ERPs) were recorded. Behavioral results showed that acceptance rates for offers increased with the fairness level of offers. Importantly, participants were less likely to accept unfair offers when they were endowed with high status than with low status. In addition, cues indicating low status elicited a more positive P2 than cues indicating high status in an earlier time window (170 - 240 ms), and cues indicating high status elicited a more
In the course of the fifth century, the Roman farms and villas of lowland Britain were replaced by the new, distinctive settlements of Anglo-Saxon communities. This volume presents a major synthesis of the evidence, now rapidly growing, for such settlements from across England and throughout the Anglo-Saxon period. Its aim is to explore what this evidence reveals about the communities who lived in them and whose daily lives went almost wholly unrecorded. The book examines the appearance, life-cycles and function of their buildings; the relationship of Anglo-Saxon settlements to the Romano-British landscape and to later medieval villages; the role of ritual in daily life; what distinguished rural from urban; and the relationship between farming regimes and settlement forms. A central theme throughout the book is the impact on rural producers of the rise of lordship and markets, and how this impact is reflected in the remains of their settlements.
Ranking high in the social hierarchy is a good predictor of robust health - in both monkeys and humans.. Being at the bottom of the social ladder is generally a predictor of bad health: research shows that poor people die sooner and have more disease than rich people, even when you account for factors like lack of access to health care.. But the data on social hierarchy and health - including studies in primates other than humans - contains a paradox for males: high status is linked with high levels of testosterone, and high testosterone can in turn lower immunity and increase disease risk. So, why is high rank consistently associated with good health? A new study in baboons sheds new light on the connections.. (Click here to read more).

This article explores the social sustainability of the basic water agenda. It does so through a biopolitical analysis of water narratives from eThekwini municipality, South Africa, where a policy of Free Basic Water (FBW) has been implemented. The article addresses the question of what water is and does and shows that water and water governance are productive of lifestyles, peoples self-understanding and how they view their place in the social hierarchy. The analysis brings to light that a differentiated management system, that provides different levels of water services to different populations and individuals, becomes part of (re)producing social hierarchies and deepens divisions between communities. Based on these findings, the article argues that while the basic water agenda has brought successful results globally and remains important in terms of guaranteeing health and survival for the most vulnerable, it should not be confused with efforts of social sustainability.

Lizzie Duke, Reporter. With the recent news that Pierce College Puyallup is infested with mice and rats, an inside look at the animals attending the college was definitely necessary.. There are many technical differences between rats and mice. Rats are much bigger than mice (about three times the size). Mice are more social than rats and have hairy tails while rats dont. Mice also scent mark, which is for their social hierarchy. Since rats have no social hierarchy, they dont feel the need to pee on things as much. The Fancy Mouse was the only kind of mouse PetSmart had for observing purposes. Its a tiny creature with massive ears, strongly resembling Jerry from Tom and Jerry, only smaller and less cartoony.. The mice spent a lot of time twitch cleaning themselves, running their hands down their little noses. This action is unbearably cute, especially when coupled with their little squeaks. According to one PetSmart worker, mice are very clean, but their environment isnt.. They are also vary ...
To investigate the role of social hierarchy in the behavior of Nlgn3y/- mice and their wild-type (Nlgn3y/+) littermates, we analyzed the behavior of mice from litters consisting of both genotypes (MGH) in comparison to litters in which male mice were all of the same Nlgn3y/+ genotype (SGH). As previously reported (Radyushkin et al., 2009; Fischer and Hammerschmidt, 2011), Nlgn3y/- mice from MGH emitted fewer ultrasonic vocalizations during courtship in comparison to Nlgn3y/+ from MGH [Nlgn3y/+ 22.2 ± 3.5 s and Nlgn3y/- 9.8 ± 2.8 s, P = 0.007, F(18,16) = 1.49; Fig. 2A]. Additionally, in the tube test, Nlgn3y/- mice from MGH lost more frequently when competing against Nlgn3y/+ mice from MGH (Nlgn3y/+ 72.9% ± 9.8% and Nlgn3y/- 29.4% ± 10.3%; P = 0.0074; Fig. 2B), suggesting that they are socially submissive to their wild-type littermates (Wang et al., 2011). In groups of mice with a stable social hierarchy, there is a correlation between ranking in courtship vocalization and in the tube test ...
The Anglo-Saxons did not settle in an abandoned landscape on which they imposed new types of settlement and farming, as was once believed. By the late 4th century the English rural landscape was largely cleared, generally occupied by dispersed farms and hamlets, each surrounded by its own fields but often sharing other resources in common (called infield-outfield cultivation).[115] Such fields, whether of prehistoric or Roman origin, fall into two very general types, found both separately and together: irregular layouts, in which one field after another had been added to an arable hub over many centuries; and regular rectilinear layouts, often roughly following the local topography, that had resulted from the large-scale division of considerable areas of land. Such stability was reversed within a few decades of the 5th century, as early Anglo-Saxon farmers, affected both by the collapse of Roman Britain and a climatic deterioration which reached its peak probably around 500, concentrated on ...
Recent work analysing the Y chromosome and mitochondrial DNA of people now living in Britain and on the continent has provided some insight into how population movements might have occurred during the Sub-Roman period. A 2002 study from University College London (Weal et al.) was interpreted as showing that there may have indeed been substantially large scale Anglo-Saxon migration to central and eastern England (accounting for 50-100% of the population at the time in Central England). [6] However, a more complete study in 2003 (Capelli et al.), suggests that the results interpreted as indicating that there may have been substantially less Anglo-Saxon migration to other regions of England, and that the transition between England and Wales is more gradual than the earlier study suggested. The study also provides evidence that all areas of the British Isles have some pre-Anglo-Saxon genetic component. It was also unable to find discernible difference in the Y-chromosomes of the presumed modern day ...

Genes related to RNA processing and translation showed higher rates of expression in young larvae (first and second instars) than in older larvae (Table 1). RNA helicase was strongly expressed by young larvae, as was an RNA-binding protein and translation elongation factor 2. Interestingly, two heat-shock proteins also were overexpressed in the youngest larvae. One shows a significant match to the Hsp70 family, whereas the second matches Hsp90. Heat-shock proteins are named for their ubiquitous presence following hyperthermy and other stresses [12], but members of this group have a more general role as molecular chaperones, and are involved in the assembly of newly translated proteins [13]. Hsp90 appears to be involved in the assembly of steroid hormone receptors [13]. Expression analyses on a more precise time scale, and at the level of specific tissues, should help determine whether the covariance between the expression of Hsps and agents involved in RNA processing reflects a joint role in ...
Being at the very top of a social hierarchy may be more costly than previously thought, according to a new study of wild baboons led by a Princeton University ecologist. A new study has found that in wild baboon populations, the highest-ranking, or alpha, males have higher stress-hormone levels than the highly ranked males below them, known as beta males -- even during periods of stability.

A growing number of countries are introducing some form of nurse prescribing. However, international reviews concerning nurse prescribing are scarce and lack a systematic and theoretical approach. The aim of this review was twofold: firstly, to gain insight into the scientific and professional literature describing the extent to and the ways in which nurse prescribing has been realised or is being introduced in Western European and Anglo-Saxon countries; secondly, to identify possible mechanisms underlying the introduction and organisation of nurse prescribing on the basis of Abbotts theory on the division of professional labor. A comprehensive search of six literature databases and seven websites was performed without any limitation as to date of publication, language or country. Additionally, experts in the field of nurse prescribing were consulted. A three stage inclusion process, consisting of initial sifting, more detailed selection and checking full-text publications, was performed independently

Frequently, when following vigorous and often repeated flushing of follicles at egg retrieval they fail to yield eggs, it is ascribed to Empty Follicle Syndrome. This is a gross misnomer, because all follicles contain eggs. So why were no eggs retrieved from the follicles? Most likely it was because they would/could not yield the eggs they harbored.This situation is most commonly seen in older women, women who have severely diminished ovarian reserve, and in women with polycystic ovarian syndrome (PCOS). In my opinion it is often preventable when an optimal, individualized and strategic protocol for controlled ovarian stimulation (COS) is employed and the correct timing and dosage is applied to the hCG trigger shot.Normally, following optimal ovarian stimulation, the hCG trigger shot is given for the purpose of it triggering meiosis (reproductive division) that is intended to halve the number of chromosomes from 46 to 23 within 32-36 hours. The hCG trigger also enables the egg to signal ...
CHAPTER IV.. THE JUDICIAL SYSTEM OF THE ANGLO-SAXONS.. SECTION I. Trial by Jury unknown to the Anglo-Saxons.. IN his admirable edition of Blackstones Commentaries,1 Mr. Sergeant Stephen says, that When the Anglo-Saxon memorials are carefully scrutinized, we find them to be such as even to justify a doubt whether trial by jury (in any sense approaching to our use of that term) did actually exist among us at any time before the Norman Conquest. This statement is, I believe, short of the truth. It may be confidently asserted that trial by jury was unknown to our Anglo-Saxon ancestors; and the idea of its existence in their legal system has arisen from a want of attention to the radical distinction between the members or judges composing a court, and a body of men apart from that court, but summoned to attend it in order to determine conclusively the facts of the case in dispute. This is the principle on which is founded the intervention of a jury; and no trace whatever can be found of such an ...

A trip has separated. A visitor becomes sick on the trip. A concession stand is backed up at lunch time. Occurrences like these are commonplace within an amusement park, and every time this event occurs it could develop main line backup. Together with the proper queue management technology set up, queue managers may acquire real-time alerts via text or email to inform them whenever a queue has fallen from sync, enabling them to control accordingly. Though theme parks may seem to the outsider like utter chaos, successful areas are finely tuned operations that benefit top-notch customer care and make every effort to supply it, particularly when it concerns waiting lines. Consult with a queue management expert in what intelligent queue management technology can perform for your amusement park.. ...
In this paper the following queueing system is investigated: A single server facility operates on a First Come First Served (FCFS) basis with Poisson arrivals and exponential service distribution. An arriving customer may either join the end of the queue or he may chose to balk at no cost. It is assumed that a customer who balks never returns to the system. Customers are risk neutral, have identical cost per unit of service and waiting time, and receive a given identical benefit at the instant of their service completion. Since waiting time is an increasing function of the queue length, and since service time is exponentially distributed, customers behavior is of a control limit type: There is a reservation length (equivalent to the reservation wage concept in Search Theory) such that an arriving customer joins the queue if and only if the queue is shorter than this value. Moreover, Naors assumptions guarantee that a customer who joins the queue will not balk at a latter time since his position in the

An order controller stores each received event in a separate entry in one of at least two queues with a separate counter value set from an arrival order counter at the time of storage, wherein the arrival order counter is incremented after storage of each of the received events and on overflow the arrival order counter wraps back to zero. The order controller calculates an absolute value of the difference between a first counter value stored with an active first next entry in a first queue from among the at least two queues and a second counter value stored with an active second next entry in a second queue from among the at least two queues. The order controller compares the absolute value with a counter midpoint value to determine whether the first counter value was stored before the second counter value.
Your job is to be a leader, not a boss, not a dictator. Leadership is a huge responsibility.

We refer to the collectivist consciousness as simian in that it may be viewed as a regression to our ancestral primate life in a group or herd, in a paradise where nature produced the fruits/food, and work did not matter, but obedience to social order did, If the social hierarchy was disobeyed, the rebels were expelled from paradise and were condemned to an exile where they had to work for their living….. Thou shalt labour…etc. Further allegory might be drawn from the need for a Saviour to lead these unfortunates back to their paradise. For the simians, being expelled from the social order and having to work was a punishment. For the Individualist, it was - and still is - an opportunity for self-fulfillment and enrichment ...
Modeling depression in animals is based on the observation of behaviors interpreted as analogue to human symptoms. Typical tests used in experimental depression research are designed to evoke an either-or outcome. It is known that explorative and coping strategies are relevant for depression, however these aspects are generally not considered in animal behavioral testing. Here we investigate the Flinders Sensitive Line (FSL), a rat model of depression, compared to the Sprague-Dawley (SD) rat in three independent tests where the animals are allowed to express a more extensive behavioral repertoire. The multivariate concentric square field T (MCSF) and the novel cage tests evoke exploratory behaviors in a novel environment and the home cage change test evokes social behaviors in the re-establishment of a social hierarchy. In the MCSF test, FSL rats exhibited less exploratory drive and more risk-assessment behavior compared to SD rats. When re-exposed to the arena, FSL, but not SD rats, increased ...
What makes a population healthy? The economic structure of a nation may be the most important determinant of the health of its citizens. People living in countries or regions where the economic gap between the rich and poor is small are healthier than those living in countries or regions where the gap is larger.. Dr. Stephen Bezruchka, an Emergency Room physician and senior lecturer at the University of Washington, has extensively researched population health and social hierarchy.. We need to think of health as the expression of our lifes experiences. We all know the physical effect that stress has on our minds and bodies, our immune system and our ability to fight disease. The reason poorer people have poorer health has something to do with the basic nature of living in poverty, Bezruchka comments.. The effects of class and social ranking affect your parents physiology and thus your biology at a very early age. Studies suggest that the critical time for health is from conception to age ...

I think we should start by jettisoning the notion -- a central dogma of neoclassical economics -- that economic efficiency is entirely or even primarily about allocational efficiency. It just isnt so. Allocational efficiency matters, but in the organization of the economy, the opportunity costs of trade-offs on the putative frontier of production possibilities are normally dominated by the inframarginal problems of controlling production processes by means of social hierarchies using operational models and feedback from error to manage in an administrative sense. Waste and depletion are necessary costs and learning from experience, particularly from a non-local public vantage point (as illustrated in the antibiotic example), poorly conceptualized in the opportunity cost framework and the misplaced faith in the information processing capacity of Hayekian market prices. Do you honestly think the externality of reducing the effectiveness of legitimate antibiotic treatment could be priced ...
Weaning is a physiological and unavoidable period in mammals life but, at the same time, it is extremely stressful. There are several stressors in animal life at this age, both psychosocial and physical: separation from the sow and the littermate, dietary and environmental change, a new social hierarchy with unknown piglets. The result is a severe impairment of intestinal integrity. The intestinal mucosa is the first line of defense against pathogens. The mucosal epithelium is an enterocytes monolayer, columnar cells linked together by protein bridges (the tight junctions) that avoids the uncontrolled passage of molecules and pathogens. Stressors cause the disruption of a large part of these bridges and affect the intestinal barrier function. This is at the basis of the increase in post-weaning pathologies, toxemia, and infections. Even if there are no clinical signs, it is demonstrated that there are heavy repercussions on growth performance throughout pigs productive life, not only during ...

Sharp Objects brings art to the television screen. If some of David Lynchs work paints a beautiful suburban environment with awful hiding in the cracks, then HBOs Sharp Objects doesnt hide evil. Based on Gillian Flynns debut 2006 novel by the same name, Sharp Objects is about Camille Preaker (portrayed by Amy Adams), a reporter who goes back to her hometown of Wind Gap, Missouri to report on the brutal murder of a young girl, and another who has gone missing.. The setting of the series is like True Detective season 1 setting, but Id say it surpasses TD. An ugly green, grimy place and a kind of place that you would drive past on a road trip. It would give you a strange feeling but the town, for how isolated it feels, has its own social hierarchy, and it is like its own little world. To compare it to David Lynchs work again, Twin Peaks is a place of ethereal beauty of Americana and Wind Gap is a suburban hell on earth, unafraid to show its true nature..

TY - JOUR. T1 - On a generic class of two-node queueing systems. AU - Adan, I.J.B.F.. AU - Mandjes, M.R.H.. AU - Scheinhardt, W.R.W.. AU - Tzenova, E.I.. PY - 2009. Y1 - 2009. N2 - This paper analyzes a generic class of two-node queueing systems. A first queue is fed by an on-off Markov fluid source; the input of a second queue is a function of the state of the Markov fluid source as well, but now also of the first queue being empty or not. This model covers the classical two-node tandem queue and the two-class priority queue as special cases. Relying predominantly on probabilistic argumentation, the steady-state buffer content of both queues is determined (in terms of its Laplace transform). Interpreting the buffer content of the second queue in terms of busy periods of the first queue, the (exact) tail asymptotics of the distribution of the second queue are found. Two regimes can be distinguished: a first in which the state of the first queue (that is, being empty or not) hardly plays a role, ...
A scheduler for a network processor includes a scheduling queue in which weighted fair queuing is applied. The scheduling queue has a range R. Flows are attached to the scheduling queue at a distance D from a current pointer for the scheduling queue. The distance D is calculated for each flow according to the formula D=((WF FS)/SF), where WF is a weighting factor applicable to a respective flow; FS is a frame size attributable to the respective flow; and SF is a scaling factor. The scaling factor SF is adjusted depending on a comparison of the distance D to the range R.
Id: queue.inc,v 1.5 1995/01/17 13:38:39 billl Exp $ COMMENT Handle a synaptic queue used to store spike arrival times for subsequent activation of a synapse after a delay. Actually the time that is stored is (arrival + delay). This is necessary because several spikes may arrive during the course of synaptic activation. These times must be kept track of if they are to influence subsequent events. A queue uses FIFO (first in, first out; cf stack -, FILO) which allows times that are stored to be picked up in the order that they are stored. This is NOT a general use queue. In particular the function of this queue depends on the use of 1e20 as a default never time that is used by both popq and pushq to determine if the queue is exhausted.
