description: This article analyzes economic tradeoffs among harvest date, fertilizer applied, nutrient removal, and switchgrass yield as they vary with respect to input and output prices. Economic sensitivity analyses suggest that higher biomass prices lead to earlier harvest. Optimal harvest time occurs beyond time of maximum yield because nutrient removal in the biomass is an important economic consideration. Switchgrass price premia that reflect the cost of nonoptimal harvest time are driven by standing crop yield loss, nutrient removal, storage loss, and opportunity cost. These price premia could provide a mechanism to compensate producers for alternative harvest times and aid with logistics management.

Driver Understanding of the Flashing Yellow Arrow and Dynamic No Turn on Red Sign for Right Turn Applications
Creators: name: Casola, Elizabeth
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Since their introduction to the 2009 Edition of the Manual on Uniform Traffic Control Devices, flashing yellow arrows (FYA) have had significant success in communicating the permissive turn message. While widely used for the permissive left turn maneuver, agencies recently have been utilizing flashing yellow arrows for the use with right turn applications as drivers interact with crossing pedestrians. As pedestrian conflicts are a concern during the permissive green phase, there is additional worry for the potential interaction between a pedestrian and vehicle turning right on red. This research explores the existing driver comprehension of permissive right turns during both green and red phases through static evaluation and microsimulation. Proposed traffic devices including the FYA and the Dynamic No Turn on Red sign were evaluated in relation to the existing signal and sign conditions implemented in the field.
In comparing the proposed FYA to the existing circular green signal, the survey evaluation determined a statistically significant increase in drivers’ yielding responses when interacting with the FYA as opposed to the circular green. Through application of the VISSIM program, it was determined that right turning speeds with the FYA present were significantly lower than when interacting with solely the circular green. Both the static evaluation and microsimulation determined a strong similarity between the existing circular red and R10-11 sign and the proposed dynamic no turn on red sign which verifies the strong understanding drivers have of the message and the sign itself.

description: The traditional education consists of teacher and the student and a “space”
where the teacher can give lessons. These spaces might have started as under
the tree moving into outdoors classroom with furniture and then into the
enclosed classrooms (four-walled space with rows of furniture). How can new
spaces unfold the layers of playfulness and haptic experience and utilize them to
enrich early childhood education? This thesis is based on envisioning new
spaces through storytelling. Presented in a series of children books that set-up a
mind frame, which helps to better understand the children needs and
behaviors. The design strategy is to create poetic and haptic spaces through
storytelling and sculpting in imaginative narratives to help children learn and
play in more attuned environments.

Does the Way Parents Fight Matter? Parents' Conflict Resolution Styles and Children's Internalizing and Externalizing Problems
Creators: name: Craft, Alexandrea L.
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Although the negative associations between marital conflict and children’s adjustment are well documented, less is known about how marital conflict styles (e.g., engagement, withdrawal, problem solving and compliance) are related to children’s developmental outcomes. The present study seeks to determine what types of parents’ conflict styles, during the child’s first year of life, are related to children’s behavioral outcomes in the first grade. Analyses examine the hypothesis that more conflictual conflict resolution styles of parents during a child’s infancy will predict poorer child outcomes over time. In addition, given the growing literature documenting the first year of life as a particularly sensitive period in children’s development, the proposed study will explore the effect of parents’ conflict resolution styles in the child’s first year of life on child outcomes at age six, controlling for concurrent levels of conflict. Lastly this study will explore the interaction of parents’ conflict resolution style in predicting children’s outcomes. Conflict resolution style and children outcomes were examined in a sample of 153 working-class, first-time parents and their children. Participants were recruited through prenatal classes at hospitals and birth clinics, as well as through Women, Infants, and Children (WIC) offices in Western Massachusetts.
Does the Elicitation Mode Matter? Comparing Different Methods for Eliciting Expert Judgement
Creators: name: Cruickshank, Claire
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: An expert elicitation is a method of eliciting subjective probability distributions over key parameters from experts. Traditionally an expert elicitation has taken the form of a face-to-face interview; however, interest in using online methods has been growing. This thesis compares two elicitation modes and examines the effectiveness of an interactive online survey compared to a face-to-face interview. Differences in central values, overconfidence, accuracy and satisficing were considered. The results of our analysis indicated that, in instances where the online and face-to-face elicitations were directly comparable, the differences between the modes was not significant. Consequently, a carefully designed online elicitation may be used successfully to obtain accurate forecasts.

description: Planned CMB Stage IV experiments have the potential to measure the effective number of relativistic degrees of freedom in the early Universe, $N_\text{eff}$, with percent-level accuracy. This probes new thermalized light particles and also constrains possible new-physics interactions of Dirac neutrinos. Many Dirac-neutrino models that aim to address the Dirac stability, the smallness of neutrino masses or the matter--anti-matter asymmetry of our Universe endow the right-handed chirality partners $ν_R$ with additional interactions that can thermalize them. Unless the reheating temperature of our Universe was low, this leads to testable deviations in $N_\text{eff}$. We discuss well-motivated models for $ν_R$ interactions such as gauged $U(1)_{B-L}$ and the neutrinophilic two-Higgs-doublet model, and compare the sensitivity of SPT-3G, Simons Observatory, and CMB-S4 to other experiments, in particular the LHC.

description: Several studies have shown that traditional vegetables have high market potential and contribute substantially to household incomes and nutrition. Until recently however, the scientific and donor community often give less attention to research on traditional vegetable crop value chains. The resurgence of traditional vegetables’ importance in human nutrition is accompanied by a need to understand the interactions among various actors in their value chain to determine ways to add value to produce and improve marketing efficiency. Based on a multistage cross-sectional survey of 240 respondents in Malawi and Mozambique, this study employed participatory evaluation and market research to identify potential outlets and target crops, and define value chain processes, including choice of market outlets and mode of farmer-buyer linkages. Traditional vegetable sales contributed about 35% and 30% of smallholders’ income in Malawi and Mozambique respectively. Linkages between value chain actors were found to be weak; mostly based on spot market transactions, except for those between retailers and supermarkets, which were based on relationship marketing.

description: The hadronic structure function of the photon F_2^gamma is measured as a function of Bjorken x and of the factorisation scale Q^2 using data taken by the OPAL detector at LEP. Previous OPAL measurements of the x dependence of F_2^gamma are extended to an average Q^2 of 767 GeV^2. The Q^2 evolution of F_2^gamma is studied for average Q^2 between 11.9 and 1051 GeV^2. As predicted by QCD, the data show positive scaling violations in F_2^gamma. Several parameterisations of F_2^gamma are in agreement with the measurements whereas the quark-parton model prediction fails to describe the data.

description: Distintictive features of supersolids show up in their rotational properties. We calculate the moment of inertia of a harmonically trapped dipolar Bose-Einstein condensed gas as a function of the tunable scattering length parameter, providing the transition from the (fully) superfluid to the supersolid phase and eventually to an incoherent crystal of self-bound droplets. The transition from the superfluid to the supersolid phase is characterized by a jump in the moment on inertia, revealing its first order nature. In the case of elongated trapping in the plane of rotation we show that the the moment of inertia determines the value of the frequency of the scissors mode, which is significantly affected by the reduction of superfluidity in the supersolid phase. The case of isotropic trapping is instead well suited to study the formation of quantized vortices, which are shown to be characterized, in the supersolid phase, by a sizeable deformed core, caused by the presence of the sorrounding density peaks.

description: Delays in the process of diagnosing and treating cancer are common and lead to confusion and undesirable outcomes. Care coordinators are often embedded within the system of care to manage follow-up care. Electronic and real-time reminder systems can be used to support the care coordinator’s work, but electronic health record (EHR) usability is known to be poor. This study, completed in collaboration with the Department of Veterans Affairs (VA) Connecticut Healthcare System, evaluated the Cancer Coordination and Tracking System (CCTS), an EHR-linked, web-based tool for cancer care management.
A set of expert-driven and user-driven usability engineering methods was applied to comprehensively identify and analyze usability problems within the system. Ten current CCTS users were engaged in the study to help identify problem. 101 (62.3%) problems were identified through expert-driven methods, 56 (34.6%) were identified by user-driven methods, and 5 (3.1%) were identified through both types of methods. The list of 162 unique problems were prioritized and twelve high priority problems were highlighted. Design recommendations were developed to address each of these high priority problems.

description: We study the decay $ϕ\toγK^+K^-$ taking into account the scalar mesons production $ϕ\toγ(f_0+a_0) \toγK^+K^-$ and the final state radiation. We note that the relative sign between the final state radiation amplitude and the scalar meson production amplitude is fixed in the $K^+K^-$ loop model which describes data on the $ϕ\to γf_0\toγππ$ and $ϕ\toγa_0\toγπη$ decays. As consequence this model predicts the definite interference between the final state radiation and the scalar resonance production amplitudes. We calculate the mass spectra of the $ϕ\toγK^+K^-$ decay and the differential cross-sections for $e^+e^-\toϕ\toγK^+K^-$ and for $e^+e^-\toϕ\toγK^0\bar K^0$ reactions.

Knowledge, Attitudes and Behaviors of Traditional Health Practices Among Cambodian Women (15-35 Years) Living In Massachusetts
Creators: name: Dou, Nan
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Cambodian immigrants have become a large population group in the United States since late 1970s. Traditional heath practices and alcohol consumption during pregnancy and lactation have both been associated with risks of maternal and child health in previous research. However, these associations have never been investigated in the Cambodian immigrant population. The mechanism for the potential interaction is that the traditional health practice, the use of sraa t’nam, which is an alcohol concoction usually consumed during postpartum period, may increase risks for both mothers and children. Sraa t’nam is the traditional alcohol and drinking alcohol during pregnancy and while lactation is not recommended. This study examined the knowledge, attitudes and behaviors of traditional health practices among Cambodian women aged between 15-35 years old living in Massachusetts. Health insurance, acculturation and food security scores were not independently associated with the dependent variable. The odds of ‘ever used sraa t’nam’ were higher (OR 1.67, CI 1.10, 2.51, p<0.05) with every one unit or one person increase in household size, after adjusting for covariates. Similarly, women with at least one child had a 4.54 odds (CI 1.24, 16.5) of reporting that they 'ever used psraa t’nam’ compared to women with no children (p<0.05)  U.S.-born women (OR 0.12, CI 0.02, 0.83, p<0.05) and those with more than a high school education (OR 0.13, CI 0.02, 0.71, p<0.05) had lower odds of having  'ever used (psraa t’nam’. Age was independently associated with having ‘ever used sraa t’nam’ (OR 1.32, CI 1.01, 1.74, p<0.05); for every year older,  the odds of ever using sraa t’nam increased by 0.32 units. In summary, women who lived in larger households, had at least one child, were foreign-born, had less education, or were older in age had higher odds of reporting that they had ‘ever used sraa t’nam’. Univariate analyses tested for associations between intention to breastfeed, age, smoking status, and intention to use sraa t’nam. Age was positively associated with the intention to breastfeed (OR=1.26, p<0.05), and smoking was also positively associated with the intention to breastfeed (OR=4.81, p<0.05).
Integrating Cover Crop Mixtures and No-Till for Sustainable Sweet Corn Production in the Northeast

Year: 2018

description: Fall-planted forage radish (Raphanus sativus L. longipinnatus) cover crops have shown successful weed suppression and recycling of fall-captured nutrients. This research evaluated the nutrient cycling and weed suppressive benefits of forage radish cover crop mixtures to develop an integrated system for no-till sweet corn (Zea mays L. var rugosa) production that improves crop yield and soil health. Treatments included forage radish (FR), oats (Avena sativa L.) and forage radish (OFR), a mixture of peas (Pisum sativum subsp arvense L.), oats and forage radish (POFR), and no cover crop control (NCC). Subplots were assigned to nitrogen fertilizer treatments to evaluate N sufficiency and timing: 0 kg N ha-1 as the control, 28 kg N ha-1 at side-dress, and 56 kg N ha-1 with application split between planting and side-dress. Results indicated that POFR and OFR provided improved N cycling and sweet corn yield compared with FR and NCC. Early season N from decomposing cover crop residue was sufficient to eliminate the need for N fertilizer at sweet corn planting, thereby reducing input costs and risks of environmental pollution.

description: We solve a truncated system of coupled Dyson-Schwinger equations for the gluon and ghost propagators in SU($N_c$) Yang-Mills theories in Faddeev-Popov quantization on a four-torus. This compact space-time manifold provides an efficient mean to solve the gluon and ghost Dyson-Schwinger equations without any angular approximations. We verify that analytically two power-like solutions in the very far infrared seem possible. However, only one of these solutions can be matched to a numerical solution for non-vanishing momenta. For a bare ghost-gluon vertex this implies that the gluon propagator is only weakly infrared vanishing, $D_{gl}(k^2) \propto (k^2)^{2κ-1}$, $κ\approx 0.595$, and the ghost propagator is infrared singular, $D_{gh}(k^2) \propto (k^2)^{-κ-1}$. For non-vanishing momenta our solutions are in agreement with the results of recent SU(2) Monte-Carlo lattice calculations. The running coupling possesses an infrared fixed point. We obtain $α(0) = 8.92/N_c$ for all gauge groups SU($N_c$). Above one GeV the running coupling rapidly approaches its perturbative form.

Children's Self-Regulation during Reward Delay
Creators: name: Fontaine, Abigail
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Individuals who display high levels of reward sensitivity are motivated by and respond to reward related cues, thus exhibiting more approach-motivated behaviors. A majority of the research on physiological indices of reward sensitivity in relation to self-regulatory abilities has focused on adults or adolescents, with relatively little work examining these associations in children. Thus, the current study sought to examine whether a common neural measure of reward sensitivity, left frontal electroencephalogram (EEG) asymmetry, assessed in early childhood was predictive of children’s later self-regulation abilities in the context of reward delay. Emerging inhibitory control skills were also examined as a potential moderator of the association between reward sensitivity and self-regulation. The frontal asymmetry measure of reward sensitivity was assessed at Time 1, when children were between the ages of 4 and 7 years old. The Time 2 visit occurred 18-24 months later, at which point children completed a flanker task to assess inhibitory control and a lock-box task to measure two components of self-regulation: behavioral control (i.e., task effort and attentional focus) and emotion regulation (i.e., expressions of anger). Children with average levels of reward sensitivity showed the highest levels of overall effort (collapsed across low, moderate, and high effort scores) and the lowest levels of weak effort. Additionally, inhibitory control iv moderated the relation between reward sensitivity and effort such that children with low reward sensitivity and strong inhibitory control showed the highest levels of overall and moderate effort as well as the lowest levels of weak effort. There were no significant associations between reward sensitivity, inhibitory control, and attentional focus or anger expression. These results suggest that EEG frontal asymmetry is a useful physiological marker of reward sensitivity when predicting specific types of regulatory abilities in children.

description: We investigate the off-forward matrix element of the light cone vector operator for a dressed quark state in light-front Hamiltonian perturbation theory. We obtain the corresponding splitting functions in a straightforward way. We show that the end point singularity is canceled by the contribution from the normalization of state. Considering mixing with the gluon operator, we verify the helicity sum rule in perturbation theory. We show that the quark mass effects are suppressed in the plus component of the matrix element but in the transverse component, they are not suppressed. We emphasize that this is a particularity of the off-forward matrix element and is absent in the forward case.

Impact of Bodyweight on Tissue-Specific Folate Status, Genome Wide and Gene-Specific DNA Methylation in Normal Breast Tissues from Premenopausal Women
Creators: name: Frederick, Armina-Lyn
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Obesity has reached an epidemic level in the United States. A number of epidemiological studies have established obesity as a critical risk factor for postmenopausal breast cancer (post-BC), whereas a reverse association holds prior to menopause. A significant scientific gap exists in understanding the mechanism(s) underpinning this epidemiological phenomenon, particularly the reverse association between obesity and premenopausal breast cancer (pre-BC). This study aimed to understand how folate metabolism and DNA methylation informs the association between obesity and pre-BC. Fifty normal breast tissue samples were collected from premenopausal women who underwent reduction mammoplasty. We developed and measured the breast tissue folate by a Lactobacillus Casei microbiological assay, and the DNA methylation of LINE-1, a biomarker of genome-wide methylation, and the promoter methylation and gene expression of SFRP1, a tumor suppressor, were measured by pyrosequencing and real-time PCR. We found a high BMI is associated with increased folate level in the mammary tissue, with an increase of 2.65 ng/g of folate per every 5-unit increase of BMI (p < 0.05). The LINE-1 DNA methylation was significantly associated with BMI (p < 0.05), and marginally associated with folate concentration (p = 0.087). For the 8 CpG sites analyzed in the promoter region of the SFRP1 gene, no associations were observed for either BMI or tissue folate (p > 0.05), although a high expression of SFRP1 was observed in subjects with high BMI or high folate (p < 0.05). This study demonstrated that, in premenopausal women, obesity is associated with an increased mammary folate status, genome-wide DNA methylation and SFRP1 gene expression, indicating that the improved folate and epigenetic status is potentially responsible for the reverse association between obesity and pre-BC. More studies are warranted to further understand how obesity mediates pre-BC via altering folate metabolism and DNA methylation.

description: In the face of climate change, a number of climate variables such as temperature, precipitation, wind speed, humidity and solar radiation tend to affect water resources. This has led to changes in soil moisture, reduced stream run off, reduced ground water recharge and increased transpiration which ultimately causes deterioration of on-farm water resources. Deteriorating water resources at farm level as a result of climate change has led to decreased crop yields in sub Saharan Africa and threatens food security, livelihoods as wells as water security. Understanding factors affecting farmers’ perception of climate change effects on water resources is key in informing policies that can transform smallholder agriculture in Africa to be more resilient to the effects of climate change. This study assesses farmers’ climate change perceptions on water resources at farm-level in Kakamega County, Kenya. Using data collected from 159 farm households in Kakamega County, ordered probit was employed to assess factors affecting farmers’ perception of climate change based on water resources. The results indicate that gender, farm size, distance to the main water source, extension services, access to climate change information through radio and wealth status significantly explained levels of farmers’ perception of climate change based on water resources. The findings inform policies aimed at increasing awareness of climate change effects on on-farm water resources and consequently enhance adaptive water management strategies among smallholder farmers.

description: We present an ultrafast neural network (NN) model, QLKNN, which predicts core tokamak transport heat and particle fluxes. QLKNN is a surrogate model based on a database of 300 million flux calculations of the quasilinear gyrokinetic transport model QuaLiKiz. The database covers a wide range of realistic tokamak core parameters. Physical features such as the existence of a critical gradient for the onset of turbulent transport were integrated into the neural network training methodology. We have coupled QLKNN to the tokamak modelling framework JINTRAC and rapid control-oriented tokamak transport solver RAPTOR. The coupled frameworks are demonstrated and validated through application to three JET shots covering a representative spread of H-mode operating space, predicting turbulent transport of energy and particles in the plasma core. JINTRAC-QLKNN and RAPTOR-QLKNN are able to accurately reproduce JINTRAC-QuaLiKiz T i,e and n e profiles, but 3 to 5 orders of magnitude faster. Simulations which take hours are reduced down to only a few tens of seconds. The discrepancy in the final source-driven predicted profiles between QLKNN and QuaLiKiz is on the order 1%-15%. Also the dynamic behaviour was well captured by QLKNN, with differences of only 4%-10% compared to JINTRAC-QuaLiKiz observed at mid-radius, for a study of density buildup following the L-H transition. Deployment of neural network surrogate models in multi-physics integrated tokamak modelling is a promising route towards enabling accurate and fast tokamak scenario optimization, Uncertainty Quantification, and control applications.

description: We prove the Mumford--Tate conjecture for those abelian varieties over number fields whose extensions to C have attached adjoint Shimura varieties that are products of simple, adjoint Shimura varieties of certain Shimura types. In particular, we prove the conjecture for the orthogonal case (i.e., for the $B_n$ and $D_n^R$ Shimura types). As a main tool, we construct embeddings of Shimura varieties (whose adjoints are) of prescribed abelian type into unitary Shimura varieties of PEL type. These constructions implicitly classify the adjoints of Shimura varieties of PEL type.

description: We present quantum dimer models in two dimensions which realize metallic ground states with Z2 topological order. Our models are generalizations of a dimer model introduced in [PNAS 112,9552-9557 (2015)] to provide an effective description of unconventional metallic states in hole-doped Mott insulators. We construct exact ground state wave functions in a specific parameter regime and show that the ground state realizes a fractionalized Fermi liquid. Due to the presence of Z2 topological order the Luttinger count is modified and the volume enclosed by the Fermi surface is proportional to the density of doped holes away from half filling. We also comment on possible applications to magic-angle twisted bilayer graphene.

description: The level of quasi-stationary planetary wave (QSW) activity in the Antarctic winter stratosphere provides insights into the likely behavior of the ozone hole in the following spring months. Observation of an anomalously large amplitude of the QSW in winter stratospheric temperatures is an indicator that strong disturbances to the polar vortex are likely to occur, and may lead to large reductions in both the area of the Antarctic ozone hole area and the overall amount of stratospheric ozone that is depleted. In the sudden stratospheric warming (SSW) preconditions in 2019, the maximum QSW amplitude over Antarctica in August was approximately 12 K, which was only 2 K less than conditions prior to the unprecedented major Antarctic SSW in 2002. Under these conditions, the Antarctic SSW in 2019 has the potential to become a major SSW. The additional factors disturbing the Antarctic stratosphere in 2019 was anomalously warm sea surface temperatures (SSTs) in the central tropical Pacific Ocean and western Indian Ocean, and the descending easterly phase of the Quasi-Biennial Oscillation. The combination of these factors - the large amplitude of the QSW, the warm tropical SSTs and transitioning phase of the QBO - has the potential to cause the early disruption of the ozone hole and reduce the overall level of ozone depletion in 2019, and may also have important regional consequences for weather conditions in the Southern Hemisphere.

The Ironic Effects of Perspective-Taking on Reactions toward Illegal Immigrants
Creators: name: Adelman, Levi
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Illegal or undocumented immigration is a political hot-button issue in the United States and around the world. This study investigated social psychological factors that influence reactions toward illegal immigrants. Drawing on America’s identity as a nation of immigrants and on research showing positive effects of perspective–taking on intergroup relations, this research asks how reminders of one’s ingroup history in the U.S. and perspective-taking impact Americans emotional responses to illegal immigrants and their support for pro- and anti-immigration policies. Additionally, this research investigates whether the effects of reminders of one’s ingroup history and perspective-taking depend on people’s political orientation. Results show that the combination of thinking about one’s ingroup history and taking the perspective of illegal immigrants actually leads to more negative reactions toward illegal immigrants. Furthermore, this effect appears to be driven by conservatives as opposed to liberals. These findings raise questions about which public discourses about illegal immigration would create a consensus based on humanitarian ideals, and which discourses would increase polarization. These findings also add to the growing literature on the limitations of perspective-taking as an intervention to reduce prejudice.

description: African Indigenous Vegetables (AIVs) have the potential to contribute substantially to food and nutrition security in Kenya because of their high nutritious value for alleviating the wide spread hidden hunger. However there is a limited pool of knowledge on the AIV-innovations, this exploratory study introduces a graph-theoretic method for assessing linkages between organisations along the AIV value chains with an aim of identifying pathways of interactions between organisations. Information sharing, knowledge and resource flows were used as proxies to connote linkage. Empirical results show that the linkages between the organisations do exist, the pathway in the AIV value chain was found to be top-down approach, the organsations giving grants set the agenda with the research organisations after which information, knowledge and resource flows were passed to the marketing and extension service organisation. Then next can the processing and policy organisation and finally to the producer organisations. In this system, the producer organisation did not demand for information, knowledge and resources and thus the agenda was set for them, implying that there limited information sharing, knowledge and resource flows along the ALV value chain organisations. The role of policy is creating an enabling environment - in this study interpreted as access to information, knowledge and resources - is critical in ensuring that the organisation along the value chain have access to the information and resources needed to promote the production and utilisation of these vegetables. The envisioned optimal pathway then would be one that provides for a feedback mechanism and may not follow a linear one-sided module. Strengthening and empowering producers, extension service and marketing organisations is critical for the uptake and adaptation of inclusive innovations and technologies along the AIV value chains.
Irreducible mass and energetics of an electromagnetic black hole

description: The mass-energy formula for a black hole endowed with electromagnetic structure (EMBH) is clarified for the nonrotating case. The irreducible mass $M_{\mathrm{irr}}$ is found to be independent of the electromagnetic field and explicitly expressable as a function of the rest mass, the gravitational energy and the kinetic energy of the collapsing matter at the horizon. The electromagnetic energy is distributed throughout the entire region extending from the horizon of the EMBH to infinity. We discuss two conceptually different mechanisms of energy extraction occurring respectively in an EMBH with electromagnetic fields smaller and larger than the critical field for vacuum polarization. For a subcritical EMBH the energy extraction mechanism involves a sequence of discrete elementary processes implying the decay of a particle into two oppositely charged particles. For a supercritical EMBH an alternative mechanism is at work involving an electron-positron plasma created by vacuum polarization. The energetics of these mechanisms as well as the definition of the spatial regions in which thay can occur are given. The physical implementations of these ideas are outlined for ultrahigh energy cosmic rays UHECR) and gamma ray bursts (GRBs).
