description: In this paper we estimate the impact of CAP subsidies on farm bank loans. According to the theoretical results, if subsidies are paid at the beginning of the growing season they may reduce bank loans, whereas if they are paid at the end of the season they increase bank loans, but these results are conditional on credit constraint and on the relative cost of internal and external financing. In empirical analysis we use the FADN farm level panel data for period 1995-2007. We employ the fixed effects and the GMM models to estimate the impact of subsidies on farm loans. The estimated results suggest that (i) subsidies influence farm loans and the effects tend to be non-linear and indirect; (ii) both coupled and decoupled subsidies stimulate long-term farm loans, but the long-term loans of big farms increase more than those of small farms due to decoupled subsidies; (iii) the short-term loans are affected only by decoupled subsidies, and they are altered by decoupled subsidies more for small farms than for large farms; however (v) when controlling for the endogeneity, only the decoupled payments appear to affect loans and the relationship is non-linear.

description: The merging procedure of tree-level matrix elements and the subsequent parton shower as implemented in the new event generator SHERPA will be validated for the example of single gauge boson production at the LHC. The validation includes consistency checks and comparisons to results obtained from other event generators. In particular, comparisons with full next-to-leading order QCD calculations prove SHERPA's ability to correctly account for additional hard QCD radiation present in these processes.

description: Ciliated cells serve vital functions in the body ranging from mechano- and chemo-sensing to fluid propulsion. Specialized cells with bundles dozens to hundreds of motile cilia known as multiciliated cells (MCCs) are essential as well, where they direct fluid movement in locations such as the respiratory, central nervous and reproductive systems. Intriguingly, the appearance of MCCs has been noted in the kidney in several disease conditions, but knowledge about their contributions to the pathobiology of these states has remained a mystery. As the mechanisms contributing to ciliopathic diseases are not yet fully understood, animal models serve as valuable tools for studying cilia development and how alterations in ciliated cell function impacts disease progression. Like other vertebrates, the zebrafish, Danio rerio, has numerous ciliated tissues. Among these, the embryonic kidney (or pronephros) is comprised of both monociliated cells and MCCs and therefore provides a setting to investigate both ciliated cell fate choice and ciliogenesis. Considering the zebrafish nephron resembles the segmentation and function of human nephrons, the zebrafish provide a tractable model for studying conserved ciliogenesis pathways in vivo. In this chapter, we provide an overview of ciliated cells with a special focus on MCCs, and present a suite of methods that can be used to visualize ciliated cells and their features in the developing zebrafish. Further, these methods enable precise quantification of ciliated cell number and various cilia-related characteristics.

description: The phase diagram of a polydisperse hard sphere system is examined by numerical minimization of a discretized form of the Ramakrishnan-Yussouff free energy functional. Crystalline and glassy local minima of the free energy are located and the phase diagram in the density-polydispersity plane is mapped out by comparing the free energies of different local minima. The crystalline phase disappears and the glass becomes the equilibrium phase beyond a "terminal" value of the polydispersity. A crystal to glass transition is also observed as the density is increased at high polydispersity. The phase diagram obtained in our study is qualitatively similar to that of hard spheres in a quenched random potential.

The cardiovascular risk perception of first degree relatives of individuals with premature coronary heart disease : does gender matter?
Creators: name: Burns, Susanne Lee
Publisher: name: University of British Columbia
Year: 2009

description: The presence of premature atherosclerosis or a clinical cardiac event in a first degree relative is a significant independent risk factor predisposing a person to the development of cardiovascular, peripheral vascular or cerebrovascular disease. First degree relatives (FDRs) of coronary heart disease patients have an increased risk of death from coronary disease compared to those without a family history. Appreciation or perception of one's personal risk for coronary heart disease may be integral to the adoption of a healthful lifestyle or the need for behaviour change. Knowledge of one's risk for heart disease does not always lead to the adoption of healthful lifestyle behaviour that may reduce one's risk. This may be due to a discrepancy between an individual's perception of his or her risk and the actual risk for developing disease. Inaccurate perceptions of personal risk, whether they are over or underestimated, may reduce the likelihood of incorporating healthful lifestyle changes. Applying a descriptive correlational design, 118 individuals participating in the Family Atherosclerosis Counseling and Testing Study, underwent a cardiovascular risk factor assessment including laboratory, anthropometric and behavioural measures. Participants also were asked to give their personal subjective risk estimates. Subjective risk perception estimates were then compared to an objective epidemiological risk estimate, the Framingham risk score, to determine the level of the participant's accuracy. Data analysis determined the relationship between level of accuracy (accurate, over-estimation, or under-estimation) and the influence of gender of the FDR (the participant), gender of the index patient, the kinship relationship to the index patient, and the variables of age and education. The results revealed that participants varied in their level of risk perception accuracy with 51.3% being accurate, 47.9% as over-estimating, and 0.9% under-estimating their risk. Education was not associated with risk perception accuracy but age was significantly associated. The average age of those with accurate risk perceptions was 36.7 years (s.d. = 13.4) compared with over-estimators who were 43.9 years of age (s.d. = 12.4), on average (p = .003). The gender of the FDR and of the index patient was not associated with risk perception accuracy. The kinship relationship of the FDR to the index patient was significant: 63.3% of siblings over-estimated their risk compared to 31.5% of children (p = .001). Further study of the metabolic status and anthropometric markers suggested that over-estimators may indeed be accurate in their perception of their risk; the Framingham risk score may not be a sensitive measure of this population's risk.

description: In this paper we estimate the income distributional effects of the common agricultural policy (CAP) for farmers and landowners. Using a unique farm level panel data set from the FADN for the period 1995-2007 we employ the fixed effects, the Heckman selection bias and the GMM estimators to estimate income distributional effects of CAP subsidies. The results do not confirm the theoretical hypothesis that landowners benefit a large share of the CAP subsidies. According to our estimates, farmers gain between 60% to 95%, 80% to 178% and 86% to 90% of the total value of coupled crop/animal, coupled RDP and decupled payments, respectively. The CAP subsidies are only marginally capitalised in land rents. Our results suggest that rental rates are more responsive to structural variables and show a strong time dependency, suggesting the presence of rigidities in the EU rental markets, which constraint the adjustment of land rents to market signals and thus reduce landowners' gains from the CAP.

description: Electronic states and magnetic properties of single $Mn$ impurity and dimer doped in narrow-gap and wide-gap $III$-$V$ semiconductors have been studied systematically. It has been found that in the ground state for single $Mn$ impurity, $Mn$-$As(N)$ complex is antiferromagnetic (AFM) coupling when $p$-$d$ hybridization $V_{pd}$ is large and both the hole level $E_{v}$ and the impurity level $E_{d}$ are close to the midgap; or very weak ferromagnetic (FM) when $V_{pd}$ is small and both $E_{v}$ and $E_d$ are deep in the valence band. In $Mn$ dimer situation, the $Mn$ spins are AFM coupling for half-filled or full-filled $p$ orbits; on the contrast, the Mn spins are double-exchange-like FM coupling for any $p$-orbits away from half-filling. We propose the strong {\it p-d} hybridized double exchange mechanism is responsible for the FM order in diluted $III$-$V$ semiconductors.

In particular we derive, in the presence of general fluxes, the effective N=1 supergravity theory associated to the type IIA orientifolds with D6 branes, compactified on $T^6/(Z_2 \times Z_2)$. We construct explicit examples with different features: in particular, new IIA no-scale models, new models with cosmological interest and a model which admits a supersymmetric AdS$_4$ vacuum with all seven main moduli ($S, T_A, U_A,A=1,2,3$) stabilized.

description: Taxing sugar-sweetened beverages (SSBs) has been proposed as a means to improve U.S. diet and health and generate revenue to address obesity-related issues. A related concern is that children’s intake of SSBs, a third that of milk consumption in the late 1970s, now equals milk consumption. Displacing milk by SSBs may shortchange the buildup of bone mass, increasing the risk of fractures and osteoporosis in later life. Accordingly, we examine the effects that a 20- percent SSB tax and a 20-percent milk price subsidy would have on the diet and health of American children. We estimated US beverage demand systems and used the estimated demand elasticities to examine the impacts of the hypothetical SSB tax and milk subsidy. Our results suggest that a 20-percent tax-induced increase in soda price alone would reduce calorie intakes by 40 calories a day among children, lowering the obesity rate from 16.1 percent to 13.4 percent and the overweight rate from 32 percent to 26.9 percent. When a 20-percent price subsidy for milk is bundled with the SSB tax, children would on average decrease their calorie intake (21 calories a day) and increase their calcium intake, but the overweight and obesity rates would actually increase by around 2 percent. The seemingly contradiction between the two averages, lower calories and higher obesity, is due to the fact that the majority of children (90 percent) remain unchanged in their weight classification under the price interventions but on average reduce their calorie intake. Six percent of children increase their calorie intake and gain enough weight to cross the overweight threshold, whereas four percent of children decrease their calorie intake to improve from being overweight to healthy weight. Therefore, when averaging the effects of the price interventions, we found a decrease in calorie intake and higher overweight and obesity rates.

description: A systematic investigation has been performed to elucidate effects of Rare-Earth (RE) type and local atomic configuration on magnetic properties of icosahedral quasicrystal (iQC) and their cubic approximants (2/1 and 1/1 ACs) in the ternary Cd-Mg-RE (RE = Gd, Tb, Dy, Ho, Er, and Tm) systems. At low temperatures, iQC and 2/1 ACs exhibit spin-glass-like freezing for RE = Gd, Tb, Dy, and Ho, while Er and Tm systems do not show freezing behaviour down to the base temperature ~ 2 K. The 1/1 ACs exhibit either spin-glass-like freezing or antiferromagnetic (AFM) ordering depending on their constituent Mg content. The Tf values show increasing trend from iQC to 2/1 and 1/1 ACs. In contrast, the absolute values of Weiss temperature for iQCs are larger than those in 2/1 and 1/1 ACs, indicating that the total AFM interactions between the neighboring spins are larger in aperiodic, rather than periodic systems. Competing spin interactions originating from the long-range Ruderman-Kittel-Kasuya-Yoshida mechanism along with chemical disorder of Cd/Mg ions presumably account for the observed spin-glass-like behavior in Cd-Mg-RE iQCs and ACs.

description: Food insecurity can generate nutritional problems such as iron deficiency anemia, which in countries like Honduras is a moderate public health problem. The AgroSalud project is enhancing the iron content of beans and rice in order to improve the iron intake of vulnerable groups, especially children under five years and pregnant women. Iron- biofortified rice and beans together can reduce the deficit in iron intake by more than a 100% depending on the age group, farmer adoption and other variables. This, in turn, would increase the number of healthy (disability-adjusted life years, DALYs) years that the Honduran population could live.

description: Charged particle multiplicities in proton-proton collisions measured in the LHCb detector at a centre-of-mass energy of $\sqrt s$=7 TeV in different windows of pseudorapidity $η$, in the forward region of the vertex detector are studied by using different statistical distributions. Three distributions are compared with the data and the moments of the distributions are calculated. The data constituting two sets, one of minimum bias events and another of hard QCD events are analysed. The distributions considered derive from different functional forms based on underlying interaction dynamics. The analysis complements the multiplicity analysis done by LHCb in terms of Monte Carlo event generators. The present analysis is from a different perspective, using statistical distributions.

description: Given their 2.2 microsecond lifetime, muons must be accelerated fairly rapidly for a neutrino factory or muon collider. Muon bunches tend to be large. Progress in fixed field, alternating gradient (FFAG) lattices to meet this challenge is reviewed. FFAG magnets are naturally wide; low momentum muons move from the low field side of a gradient magnet to the high field side as they gain energy. This can be exploited to do double duty and allow a large beam admittance without unduly increasing the magnetic field volume. If the amount of RF must be reduced to optimize cost, an FFAG ring can accommodate extra orbits. I describe both scaling FFAGs in which the bends in each magnet are energy independent and non-scaling FFAGs in which the bends in each magnet do vary with muon energy. In all FFAG designs the sum of the bends in groups of magnets are constant; otherwise orbits would not close. Ways of keeping the accelerating beam in phase with the RF are described. Finally, a 1 MeV proof of principle scaling FFAG has been built at KEK and began accelerating protons in June 2000 with a 1 kHz repetition rate.

description: Consumers’ consumption patterns could be affected by food safety information, however, it is more important to consider where the food safety issue occurs. If the food safety issue happens in other countries, in other words, it outbreaks out of the target market, negative information may be beneficial; in contrast, if the food safety issue occurs within the market, results may consistent with previous studies. Based on this assumption, this paper reinvestigates the impacts of AI media coverage and BSE cases on the demand of meat in U.S. market. Estimated results provide supports for our assumption, i.e., AI information has positive effect on poultry and turkey demands in short term, and BSE affect beef demand negatively.

description: Despite significant advances in understanding nephron segment patterning, many questions remain about the underlying genes and signaling pathways that orchestrate renal progenitor cell fate choices and regulate differentiation. In an effort to identify elusive regulators of nephron segmentation, our lab conducted a high-throughput drug screen using a bioactive chemical library and developing zebrafish, which are a conserved vertebrate model and particularly conducive to large-scale screening approaches. 17β-estradiol (E2), which is the dominant form of estrogen in vertebrates, was a particularly interesting hit from this screen. E2 has been extensively studied in the context of gonad development, but roles for E2 in nephron development were unknown. Here, we report that exogenous estrogen treatments affect distal tubule composition, namely, causing an increase in the distal early segment and a decrease in the neighboring distal late. These changes were noted early in development but were not due to changes in cell dynamics. Interestingly, exposure to the xenoestrogens ethinylestradiol and genistein yielded the same changes in distal segments. Further, upon treatment with an estrogen receptor 2 (Esr2) antagonist, PHTPP, we observed the opposite phenotypes. Similarly, genetic deficiency of the Esr2 analog, esr2b, revealed phenotypes consistent with that of PHTPP treatment. Inhibition of E2 signaling also resulted in decreased expression of essential distal transcription factors, irx3b and its target irx1a. These data suggest that estrogenic compounds are essential for distal segment fate during nephrogenesis in the zebrafish pronephros and expand our fundamental understanding of hormone function during kidney organogenesis.

description: In a model for leptogenesis based on spontaneous breaking of Lorentz and CPT symmetry [1-3], we examine the consistency of using the approximation of plane-wave solutions for a free spin-(1/2) Dirac (or Majorana) fermion field propagating in a Friedmann-Lemaitre-Robertson-Walker space time augmented with a cosmic time-dependent (or, equivalently, a temperature-dependent) Kalb-Ramond (KR) background. For the range of parameters relevant for leptogenesis, our analysis fully justifies the use of plane-wave solutions in our study of leptogenesis with Boltzmann equations; any corrections induced by space-time-curvature are negligible. We also elaborate further on how the lepton asymmetry is communicated to the Baryon sector. We demonstrate that the KR background (KRB) does not contribute to the anomaly equations that determine the baryon asymmetry a) through an explicit evaluation of a triangle Feynman graph and b) indirectly, on topological grounds, by identifying the KRB as torsion (in the effective string-inspired low energy gravitational field theory).

title: Cultural constraints in digital adaptation: state ownership, agents, and newspaper organisations in China
Creators: name: Zhao, Wei
Publisher: name: University of Glasgow
Year: 2025

description: This study examines the digital adaptation of China’s state-owned newspaper firms, with a particular focus on the cultural constraints shaping their organisational capabilities for digital growth. Drawing on theories from organisational studies, media management, and media innovation, it investigates ownership as a key structural factor influencing cultural dynamics, which in turn affects the innovation capabilities of Chinese newspaper firms.

Through a multi-case study of three Beijing-based national industry newspapers, this research identifies three common cultural phenomena: self-identification as state media, symbolic compliance in policy engagement, and the accepted norm of “co-creation” between journalists and advertisers. Despite their shared state ownership, each newspaper firm exhibits distinct organisational cultures shaped by agent owners—supervisory entities responsible for exercising ownership rights on behalf of the state. By embedding their own institutional priorities and interests into organisational practices, these agent owners refract the influence of state ownership, generating varied cultural dynamics across Chinese newspaper firms. Building on this, the study further explores the motivations behind Chinese newspaper firms’ innovative behaviours, identifying three primary drivers—self-drive, state compliance, and change aversion—that either facilitate or hinder digital adaptation. The interplay of these motives, with state ownership playing a significant role, reveals a misalignment of values, goals, and expectations among policymakers, agent owners, press management, and practitioners. These cultural constraints have been limiting the innovation capabilities of Chinese newspaper firms in their pursuit of digital transformation and genuine engagement with the state-led media convergence strategy.

This study challenges the conventional view of China’s state-owned media system by critically uncovering the underexplored yet pivotal role of agent owners. It further advances media innovation research by proposing a novel motivation-based framework to decode organisational cultures and behaviours within Chinese newspaper firms, drawing on valuable empirical data. The findings call for further academic and regulatory inquiry into the power boundaries of agent owners and their conflicts of interest with Chinese newspaper firms, offering insights to mitigate agency loss in China’s media governance and address the institutional constraints on media innovation.
Public health impacts of naturally-derived particulate matter : a case study of Asian dust in southwestern British Columbia
Creators: name: Bennett, Charmian Margaret
Publisher: name: University of British Columbia
Year: 2009

description: The adverse public health impacts of anthropogenically-derived particulate matter have been well documented, with measureable increases in both morbidity and mortality rates associated with high particulate matter pollution events. Most current research has focused on the health impacts of anthropogenically-derived particulate matter, and there is a distinct scarcity of literature that examines the role of naturally-derived particulate matter and adverse health impacts in the urban context. This study of a Gobi desert dust event in British Columbia, Canada, in spring of 1998 provided a unique opportunity to identify the adverse health effects related to naturally-derived particulate matter in a large urban setting. Respiratory and cardiac hospitalizations were examined for a three-year period (January 1997 to December 1999), with the Gobi dust event occurring in late April 1998. A meteorological analogue was identified for spring 1997 in order to identify the public health impacts associated with anthropogenically-derived particulate matter and those impacts associated with the presence of the Gobi desert dust. Results indicate that this Gobi dust event was not associated with an excess of hospitalizations for the Fraser Valley region. Peak particulate matter concentrations of Gobi desert dust in the airshed were only associated with an additional two or three hospitalizations for respiratory and cardiac illnesses, and these increases were not distinguishable from the 'normal' variability in hospitalization rates. Despite high particulate matter concentrations, fine particle size, presence of heavy metals in the dust and extended exposure periods, it appears that the Gobi desert dust event was not associated with significant risk to public health in the Fraser Valley, British Columbia. Therefore it is concluded that naturally-derived particulate matter is more benign than particulate matter of anthropogenic origin, and thus poses a low risk to health for the general public.

description: In this work we introduce a metal-oxide bond-energy model for alloy oxides based on pure-phase bond energies and bond synergy factors that describe the effect of alloying on the bond energy between cations and oxygen, an important quantity to understand formation and stability of passive films. This model is parameterized for binary cation-alloy oxides using density-functional theory energies and is shown to be directly transferable to multi-component alloy oxides. We parameterized the model for alloy oxide energies with metal cations that form the basis of corrosion resistant alloys, including Fe, Ni, Cr, Mo, Mn, W, Co, and Ru. We find that isoelectronic solutes allow quantification of pure-phase bond energies in oxides and that the calculated bond energy values give sensible results compared to common experience, including the role of Cr as the passive-layer former in Fe-Ni-Cr alloys for corrosion applications. Additionally, the bond synergy factors give insights into the mutual strengthening and weakening effects of alloying on cation-oxygen bonds and can be related to enthalpy of mixing and charge neutrality constraints. We demonstrate how charge neutrality can be identified and achieved by the oxidation states that the different cations assume depending on alloy composition and the presence of defects.

description: In this paper, two AI mitigation strategies are examined, quarantine and vaccination. Meanwhile, associated welfare changes are evaluated by using FASOM. Results found that changes of total national welfare of U.S are insignificant with or without vaccination. Once comes to livestock producers, impacts become significant although magnitudes are small. For example, under 20% demand shocks, vaccination strategy dominates no vaccination at the production, market and national level. However, vaccination has no advantage when there is no demand shifts.

description: Bulk and single-particle properties of hot hyperonic matter are studied within the Brueckner-Hartree-Fock approximation extended to finite temperature. The bare interaction in the nucleon sector is the Argonne V18 potential supplemented with an effective three-body force to reproduce the saturating properties of nuclear matter. The modern Nijmegen NSC97e potential is employed for the hyperon-nucleon and hyperon-hyperon interactions. The effect of the temperature on the in-medium effective interaction is found to be, in general, very small and the single-particle potentials differ by at most 25% for temperatures in the range from 0 to 60 MeV. The bulk properties of infinite matter of baryons, either nuclear isospin symmetric or a beta-stable composition which includes a non-zero fraction of hyperons, are obtained. It is found that the presence of hyperons can modify the thermodynamical properties of the system in a non-negligible way.

description: The rapid proliferation of new users and items on the social web has aggravated the gray-sheep user/long-tail item challenge in recommender systems. Historically, cross-domain co-clustering methods have successfully leveraged shared users and items across dense and sparse domains to improve inference quality. However, they rely on shared rating data and cannot scale to multiple sparse target domains (i.e., the one-to-many transfer setting). This, combined with the increasing adoption of neural recommender architectures, motivates us to develop scalable neural layer-transfer approaches for cross-domain learning. Our key intuition is to guide neural collaborative filtering with domain-invariant components shared across the dense and sparse domains, improving the user and item representations learned in the sparse domains. We leverage contextual invariances across domains to develop these shared modules, and demonstrate that with user-item interaction context, we can learn-to-learn informative representation spaces even with sparse interaction data. We show the effectiveness and scalability of our approach on two public datasets and a massive transaction dataset from Visa, a global payments technology company (19% Item Recall, 3x faster vs. training separate models for each domain). Our approach is applicable to both implicit and explicit feedback settings.

description: It is shown that dynamics of the interface between ideal fluid and light viscous fluid is exactly integrable in the approximation of small surface slopes for two-dimensional flow. Stokes flow of viscous fluid provides a relation between normal velocity and pressure at interface. Surface elevation and velocity potential of ideal fluid are determined from two complex Burgers equations corresponding to analytical continuation of velocity potential at the interface into upper and lower complex half planes, respectively. The interface loses its smoothness if complex singularities (poles) reach the interface.

description: Research from sub-Saharan Africa has examined female motivations for having multiple, age-disparate and transactional sexual partners, but little is known about who girls turn to for specific needs. We report on a participatory tool, Ascertaining Sexual Relationship Types (ASERT), used with out-of-school adolescent girls (AG) aged 15-19 and young women (YW) aged 20-24 in three Tanzanian locations (Dar, Iringa, Mbeya). The range of sexual partner types described by the 6 groups was broader than previously documented. Of thirteen types identified, eight were age-disparate, each providing a distinct benefit, mainly structural; the remaining five were similar in age to respondents, mostly fulfilling socio-emotional needs and aspirations. The 13 types varied by lifecycle stage, socio-economic status, and potential HIV risk to AGYW. Such partner type data should inform HIV prevention programs targeted to AGYW and emphasizes the need to reach disadvantaged girls in more precise ways, and ideally before age-disparate relationships begin.

description: The anisotropy splitting in the ground state of the single-molecule magnet [Mn4O3Br(OAc)3(dbm)3] is studied by inelastic neutron scattering as a function of hydrostatic pressure. This allows a tuning of the anisotropy and thus the energy barrier for slow magnetisation relaxation at low temperatures. The value of the negative axial anisotropy parameter $D_{\rm cluster}$ changes from -0.0627(1) meV at ambient to -0.0603(3) meV at 12 kbar pressure, and in the same pressure range the height of the energy barrier between up and down spins is reduced from 1.260(5) meV to 1.213(9) meV. Since the $\rm Mn-Br$ bond is significantly softer and thus more compressible than the $\rm Mn-O$ bonds, pressure induces a tilt of the single ion Mn$^{3+}$ anisotropy axes, resulting in the net reduction of the axial cluster anisotropy.

description: We report the results of a pilot program for a Green Bank Telescope (GBT) MUSTANG Galactic Plane survey at 3 mm (90 GHz), MGPS90. The survey achieves a typical $1σ$ depth of $1-2$ mJy beam$^{-1}$ with a 9" beam. We describe the survey parameters, quality assessment process, cataloging, and comparison with other data sets. We have identified 709 sources over seven observed fields selecting some of the most prominent millimeter-bright regions between $0°< \ell < 50°$ (total area $\approx 7.5 °^2$). The majority of these sources have counterparts at other wavelengths. By applying flux selection criteria to these sources, we successfully recovered several known hypercompact HII (HCHII) regions, but did not confirm any new ones. We identify 126 sources that have mm-wavelength counterparts but do not have cm-wavelength counterparts and are therefore candidate HCHII regions; of these, 10 are morphologically compact and are strong candidates for new HCHII regions. Given the limited number of candidates in the extended area in this survey compared to the relatively large numbers seen in protoclusters W51 and W49, it appears that most HCHII regions exist within dense protoclusters. Comparing the counts of HCHII to ultracompact HII (UCHII) regions, we infer the HCHII region lifetime is 16-46% that of the UCHII region lifetime. We additionally separated the 3 mm emission into dust and free-free emission by comparing with archival 870 $μ$m and 20 cm data. In the selected pilot fields, most ($\gtrsim80$%) of the 3 mm emission comes from plasma, either through free-free or synchrotron emission.
