ALTERNATIVE DISPUTE RESOLUTION AND PEACE MAKING FOR RESOLVING AGRIBUSINESS AND FOOD MANAGEMENT CONFLICT RESOLUTION IN THE FREE TRADE AREA OF THE AMERICAS GRASS ROOTS INITIATIVES WITH INTERNATIONAL APPLICATIONS
The FTAA (Free Trade Area of the Americas) will bring together 35 countries with five different languages and over 300 ethnic and cultural groups. As trade, cultural discourse, and other joint efforts develop between countries, private organizations, public entities and individuals, many disputes will arise. In a few countries, the rule of law can solve these disputes effectively. In most others, the rule of law cannot work because of political, social or even criminal events. As NAFTA showed, developing a successful and efficient dispute resolution mechanism is an important component of developing a successful working relationship of the agreement among all the parties and countries. Other Trade Agreements including NAFTA and WTO have found that the successful functioning of these agreements require all private and public parties to think carefully about resolving disputes ahead of time and setting up a number of alternative processes to be used by the parties. Only in Government-to-Government disputes is the system quite simple. Otherwise, there are several models which have been developed in the U.S. and other American countries which can assist in resolving agribusiness and food management conflict resolution in rural communities. Grass roots initiatives with international applications, disputes over land, grazing rights, homes, credit issues and financial resources can be a serious impediment to growth. In Arizona, U.S. and the Americas, this has caused large dollar value disputes, ill will, riots and even death. In both rural and agricultural based Arizona, U.S. and the Americas, this presentation highlights methodology and courses being developed to solve some of these conflicts.Agribusiness, International Relations/Trade,

Transgenerational effects alleviate severe fecundity loss during ocean acidification in a ubiquitous planktonic copepod
Ocean acidification (OA) caused by anthropogenic CO2 emission is projected for thousands of years to come, and significant effects are predicted for many marine organisms. While significant evolutionary responses are expected during such persistent environmental change, most studies consider only short-term effects. Little is known about the transgenerational effects of parental environments or natural selection on the capacity of populations to counter detrimental OA effects. In this study, six laboratory populations of the calanoid copepod Pseudocalanus acuspes were established at three different CO2 partial pressures (pCO2 of 400, 900 and 1550 μatm) and grown for two generations at these conditions. Our results show evidence of alleviation of OA effects as a result of transgenerational effects in P. acuspes. Second generation adults showed a 29% decrease in fecundity at 900 μatm CO2 compared to 400 μatm CO2. This was accompanied by a 10% increase in metabolic rate indicative of metabolic stress. Reciprocal transplant tests demonstrated that this effect was reversible and the expression of phenotypic plasticity. Furthermore, these tests showed that at a pCO2 exceeding the natural range experienced by P. acuspes (1550 μatm), fecundity would have decreased by as much as 67% compared to at 400 μatm CO2 as a result of this plasticity. However, transgenerational effects partly reduced OA effects so that the loss of fecundity remained at a level comparable to that at 900 μatm CO2. This also relieved the copepods from metabolic stress, and respiration rates were lower than at 900 μatm CO2. These results highlight the importance of tests for transgenerational effects to avoid overestimation of the effects of OA
Epistemic Logic Programs with World View Constraints
An epistemic logic program is a set of rules written in the language of Epistemic Specifications, an extension of the language of answer set programming that provides for more powerful introspective reasoning through the use of modal operators K and M. We propose adding a new construct to Epistemic Specifications called a world view constraint that provides a universal device for expressing global constraints in the various versions of the language. We further propose the use of subjective literals (literals preceded by K or M) in rule heads as syntactic sugar for world view constraints. Additionally, we provide an algorithm for finding the world views of such programs
Control of Drosophila imaginal disc development by rotund and roughened eye: differentially expressed transcripts of the same gene encoding functionally distinct zinc finger proteins
The Drosophila rotund gene is required in the wings, antenna, haltere, proboscis and legs. A member of the Rac family of GTPases, denoted the rotund racGAP gene, was previously identified in the rotund region. However, previous studies indicated that rotund racGAP was not responsible for the rotund phenotypes and that the rotund gene had yet to be identified. We have isolated the rotund gene and show that it is a member of the Kruppel family of zinc finger genes. The adjacent roughened eye locus specifically affects the eye and is genetically separable from rotund. However, roughened eye and rotund are tightly linked, and we have therefore also isolated the roughened eye transcript. Intriguingly, we show that roughened eye is part of the rotund gene but is represented by a different transcript. The rotund and roughened eye transcripts result from the utilization of two different promoters that direct expression in non-overlapping domains in the larval imaginal discs. The predicted Rotund and Roughened Eye proteins share the same C-terminal region, including the zinc finger domain, but differ in their N-terminal regions. Each cDNA can rescue only the corresponding mutation and show negative effects when expressed in each others domain of expression. These results indicate that in addition to the differential expression of rotund and roughened eye, their proteins have distinct activities. rotund and roughened eye act downstream of early patterning genes such as dachshund and appear to be involved in Notch signaling by regulating Delta, scabrous and Serrate
Left ventricular mechanical dispersion by tissue Doppler imaging: a novel approach for identifying high-risk individuals with long QT syndrome
Forutsigelse av livstruende hjerterytmeforstyrrelser
Hjertespesialist og forsker Kristina Hermann Haugaa har i sin doktorgrad funnet en ny metode som kan brukes til å forutsi hvilke pasienter som kommer til å få alvorlige hjerterytmeforstyrrelser: Ultralyd av hjertet med ny metode kan avsløre hvem som har risiko for hjerterytmeforstyrrelser og hvem som ikke har det.
Plutselig hjertedød på grunn av hjerterytmeforstyrrelser er en av de vanligste dødsårsakene i Norge og i den øvrige vestlige verden. Den største risikogruppen er personer som har hatt hjerteinfarkt. Plutselig hjertedød hos yngre skyldes ofte arvelige hjertesykdommer.
I avhandlingen “Prediction of cardiac ventricular arrhythmias by echocardiography in patients at risk” undersøker Kristina Haugaa både yngre pasienter med arvelige hjerterytmeforstyrrelser og pasienter som har gjennomgått hjerteinfarkt med den nye metoden for hjerteultralyd. Pasientene ble fulgt i over to år etter hjerteinfarkt. Studiene viser at ujevn hjertekontraksjon er en risikomarkør for å få hjerterytmeforstyrrelser og at den nye metoden vurderer risikoen bedre enn dagens metoder. Med bedre risikovurdering kan man bedre fordele resursene for behandling. Behandlingen innebærer oftest at pasientene i tillegg til medisin får operert inn en automatisk hjertestarter. Den nye metoden som er brukt i avhandlingen vil kunne forbedre utvelgelsen av pasienter med høy risiko for død slik at disse kan utstyres med hjertestarter
Zfh1, a somatic motor neuron transcription factor, regulates axon exit from the CNS
AbstractMotor neurons are defined by their axon projections, which exit the CNS to innervate somatic or visceral musculature, yet remarkably little is known about how motor axons are programmed to exit the CNS. Here, we describe the role of the Drosophila Zfh1 transcription factor in promoting axon exit from the CNS. Zfh1 is detected in all embryonic somatic motor neurons, glia associated with the CNS surface and motor axons, and one identified interneuron. In zfh1 mutants, ventral projecting motor axons often stall at the edge of the CNS, failing to enter the muscle field, despite having normal motor neuron identity. Conversely, ectopic Zfh1 induces a subset of interneurons—all normally expressing two or more “ventral motor neuron transcription factors” (e.g. Islet, Hb9, Nkx6, Lim3)—to project laterally and exit the CNS. We conclude that Zfh1 is required for ventral motor axon exit from the CNS
