description: Using recent advances in the stochastic production frontier framework, this paper presents an empirical analysis of technical, allocative and economic efficiency of a sample of organic and conventional cotton farms located in Greece. The results suggest that both farm types in the sample examined are technically, allocatively and economically inefficient. Farmer's age and education and farm size are important factors in explaining differentials in efficiency estimates. In comparative terms, organic farms exhibit lower efficiency scores vis-à-vis their conventional counterparts in terms of technical and economic efficiency; regarding allocative efficiency both farm types are almost equally inefficient. Low efficiency scores in both types of farming may be attributed to the respective intervention policies of the last 20 years.

description: We investigate the effect of coupling between translational and internal degrees of freedom of composite quantum particles on their localization in a random potential. We show that entanglement between the two degrees of freedom weakens localization due to the upper bound imposed on the inverse participation ratio by purity of a quantum state. We perform numerical calculations for a two-particle system bound by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered lattice. We illustrate that the coupling has a dramatic effect on localization properties, even with a small number of internal states participating in quantum dynamics.

description: If agricultural output results from non-separable multiproduct technologies, environmental regulation can change the set of possible output combinations. This will be important when regulation affects the quality composition of a crop. As a result, market and welfare changes have to be assessed in technology-related markets. We present a model that serves to estimate the economic impacts in such instances and use it in the assessment of pesticide regulation in the U.S. apple industry. Impacts for four pesticide cancellation scenarios are assessed. It is shown that changes in the quality of a crop lead to significant market reallocation effects.

description: Onset of small-amplitude oscillatory and both small- and finite-amplitude steady double-component convection arising due to component different boundary conditions in an infinite slot is studied for various slot orientations to the gravity. The main focus is on two compensating background gradients of the components. The physical mechanisms underlying steady and oscillatory convection are analyzed from the perspective of a universally consistent understanding of the effects of different boundary conditions.

description: We present new measurements of the clustering of stellar mass-complete samples of $\sim40,000$ SDSS galaxies at $z\sim0.03$ as a joint function of stellar mass and specific star formation rate (sSFR). Our results confirm what Coil et al. (2017) find at $z\sim0.7$: galaxy clustering is a stronger function of sSFR at fixed stellar mass than of stellar mass at fixed sSFR. We also find that galaxies above the star-forming main sequence (SFMS) with higher sSFR are less clustered than galaxies below the SFMS with lower sSFR, at a given stellar mass. A similar trend is present for quiescent galaxies. This confirms that main sequence scatter, and scatter within the quiescent sequence, is physically connected to the large-scale cosmic density field. We compare the resulting galaxy bias versus sSFR, and relative bias versus sSFR ratio, for different galaxy samples across ${0

description: Factors unique to the turkey industry suggest that conclusions concerning market structure and demand specification drawn from aggregate poultry data cannot necessarily be extrapolated to the turkey industry. The Wu-Hausman endogeneity test is used to examine demand specifications and industry structure specifically for turkey meat. In contrast to general poultry, quantity-not price-is found to be predetermined in demand models that use annual turkey data. Quarterly demand analysis suggests this result stems from biological cycles that limit a producer's ability to react to price change and the use of a weighted average for determining price and quantity.

description: Use of the Tobit model for estimation of adult equivalent scale (AES) parameters and expenditure equations presupposes that zero observations represent exclusively corner solutions. This paper tests for the underlying causes of zero observations and estimates accordingly the AES parameters, the household size in adult equivalents and the resulting expenditure equations and consumption profiles. The empirical application concerns Greek household "soft" and "hard" cheese consumption. The statistical results indicate that for the examined cheese categories the "double hurdle participation" model adjusted for non-normality and heteroskedasticity is the appropriate model for the estimation of AES parameters and expenditure equations.

title: How localizing management affects subsidiary performance: evidence from South Korean multinational enterprises
Creators: name: Lee, Joonghak
Publisher: name: University of Reading
Year: 2025

description: This thesis investigates the crucial role of localizing management, deployment of short�term expatriates, subsidiary digitalization and subsidiary CEO experience in enhancing 
subsidiary performance within Multinational Enterprises (MNEs). It comprises three 
interrelated studies that provide a holistic view of the strategies that MNEs can adopt to 
optimize their operations in foreign markets. The first paper explores the implications of 
localizing management on subsidiary performance by considering local staffing and 
delegation of autonomy concurrently. Drawing on data from 117 subsidiaries of 20 South 
Korean MNEs, it reveals that local staffing and autonomy delegation complement each 
other, enhancing subsidiary performance when applied in tandem. Building upon this 
finding, the second study further investigates the impact of sub-components of localizing 
management (i.e., local staffing and autonomy delegation) within the evolving global 
context marked by rapid political, social, economic, and technological changes. Empirical 
analysis shows that the deployment of short-term expatriates can offset the positive 
effects of autonomy delegation on subsidiary performance. However, the paper also 
demonstrates that digitalization can mitigate these drawbacks, underscoring its 
importance in improving subsidiary performance. Lastly, the third study proposes a novel 
approach to select and develop subsidiary CEOs by focusing on their experience. Through 
a comprehensive literature review and empirical analysis, it highlights the significance of 
continuity and interaction in CEO experience, complementing the traditional emphasis 
on accumulated time. The study proposes an innovative model to conceptualize CEO 
experience with nationality, international experience and functional background, 
revealing the most effective CEO experience profiles that contribute to high subsidiary 
performance. Collectively, these papers enhance our understanding of the strategic 
significance of localizing management and CEO experience in MNEs, offering both 
theoretical insights and practical guidance for MNEs aiming to improve subsidiary 
performance. This thesis contributes to the broader field of international business by 
addressing the complexities of localizing management and identifying the dimensions of 
CEO experience that can enhance subsidiary performance in a rapidly evolving global 
landscape.

description: We propose a novel Bayesian method to analytically continue observables to real baryochemical potential $μ_B$ in finite density QCD. Taylor coefficients at $μ_B=0$ and data at imaginary chemical potential $μ_B^I$ are treated on equal footing. We consider two different constructions for the Padé approximants, the classical multipoint Padé approximation and a mixed approximation that is a slight generalization of a recent idea in Padé approximation theory. Approximants with spurious poles are excluded from the analysis. As an application, we perform a joint analysis of the available continuum extrapolated lattice data for both pseudocritical temperature $T_c$ at $μ_B^I$ from the Wuppertal-Budapest Collaboration and Taylor coefficients $κ_2$ and $κ_4$ from the HotQCD Collaboration. An apparent convergence of $[p/p]$ and $[p/p+1]$ sequences of rational functions is observed with increasing $p.$ We present our extrapolation up to $μ_B\approx 600$ MeV.

description: The low energy (<10 keV) X-ray emission of the Soft Gamma-ray Repeater SGR1806-20 has been studied by means of four XMM-Newton observations carried out in the last two years, the latter performed in response to a strong sequence of hard X-ray bursts observed on 2004 October 5. The source was caught in different states of activity: over the 2003-2004 period the 2-10 keV flux doubled with respect to the historical level observed previously. The long term raise in luminosity was accompanied by a gradual hardening of the spectrum, with the power law photon index decreasing from 2.2 to 1.5, and by a growth of the bursting activity. The pulse period measurements obtained in the four observations are consistent with an average spin-down rate of 5.5x10e-10 s/s, higher than the values observed in the previous years. The long-term behavior of SGR1806-20 exhibits the correlation between spectral hardness and spin-down rate previously found only by comparing the properties of different sources (both SGRs and Anomalous X-ray Pulsars). The best quality spectrum (obtained on 6 September 2004) cannot be fitted by a single power law, but it requires an additional blackbody component (kT=0.79 keV, R_BB = 1.9 (d/15 kpc)^2 km), similar to the spectra observed in other SGRs and in Anomalous X-ray Pulsars. No spectral lines were found in the persistent emission, with equivalent width upper limits in the range 30-110 eV. Marginal evidence for an absorption feature at 4.2 keV is present in the cumulative spectrum of 69 bursts detected in September-October 2004.

description: We discuss the effect of subdividing the ratchet potential on the performance of a tiny Brownian heat engine that is modeled as a Brownian particle hopping in a viscous medium in a sawtooth potential (with or without load) assisted by alternately placed hot and cold heat baths along its path. We show that the velocity, the efficiency and the coefficient of performance of the refrigerator maximize when the sawtooth potential is subdivided into series of smaller connected barrier series. When the engine operates quasistatically, we analytically show that the efficiency of the engine can not approach the Carnot efficiency and, the coefficient of performance of the refrigerator is always less than the Carnot refrigerator due to the irreversible heat flow via the kinetic energy.

We find evidence of divergent validity and differences in the willingness to pay estimates from the single-bound and multiple-bound data.

Quantum Elliptic Vortex in a Nematic-Spin Bose-Einstein Condensate

description: We find a novel topological defect in a spin-nematic superfluid theoretically. A quantized vortex spontaneously breaks its axisymmetry, leading to an elliptic vortex in nematic-spin Bose-Einstein condensates with small positive quadratic Zeeman effect. The new vortex is considered the Joukowski transform of a conventional vortex. Its oblateness grows when the Zeeman length exceeds the spin healing length. This structure is sustained by balancing the hydrodynamic potential and the elasticity of a soliton connecting two spin spots, which are observable by in situ magnetization imaging. The theoretical analysis clearly defines the difference between half quantum vortices of the polar and antiferromagnetic phases in spin-1 condensates.

description: Some suppliers of broilers without giblets (WOG) offer customers a choice between paying Urner Barry's WOG quote or a formula price based on futures prices. From a buyer's perspective, the formula price examined in this study is second-degree stochastic dominant. The formula price allows the seller to set perfect cross-hedges of WOGs with corn and soymeal. Stochastic dominance and mean variance results suggested that the seller's dominant strategy would shift from the Urner Barry quote to the hedged formula price as risk aversion increased. Input-based formula pricing may be usefully extended to other industries.

description: In MENA, household food insecurity, which is closely related to poverty and undernourishment, is most severe in rural areas and concentrated within Iraq, Sudan, and Yemen. 25% of the MENA population may be poor and 7% undernourished. The key to increased national and household-level food security is pro-poor growth, driven by export-oriented, labor-intensive sectors. Agricultural sector policies should be subordinate to the pro-poor growth goal and not to the goal of food self-sufficiency. Such a strategy requires conflict resolution; macroeconomic stability; physical and human capital accumulation; reliance on markets and the private sector, and diffusion of ecologically friendly farming practices.

Phenomenology of Dirac Neutrinogenesis in Split Supersymmetry

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In Split Supersymmetry scenarios the possibility of having a very heavy gravitino opens the door to alleviate or completely solve the worrisome "gravitino problem'' in the context of supersymmetric baryogenesis models. Here we assume that the gravitino may indeed be heavy and that Majorana masses for neutrinos are forbidden as well as direct Higgs Yukawa couplings between left and right handed neutrinos. We investigate the viability of the mechansim known as Dirac leptogenesis (or neutrinogenesis), both in solving the baryogenesis puzzle and explaining the observed neutrino sector phenomenology. To successfully address these issues, the scenario requires the introduction of at least two new heavy fields. If a hierarchy among these new fields is introduced, and some reasonable stipulations are made on the couplings that appear in the superpotential, it becomes a generic feature to obtain the observed large lepton mixing angles. We show that in this case, it is possible simultaneously to obtain both the correct neutrino phenomenology and enough baryon number, making thermal Dirac neutrinogenesis viable. However, due to cosmological constraints, its ability to satisfy these constraints depends nontrivially on model parameters of the overall theory, particularly the gravitino mass. Split supersymmetry with m_{3/2} between 10^{5} and 10^{10} GeV emerges as a "natural habitat" for thermal Dirac neutrinogenesis.

description: MAXI J1820+070 is a newly-discovered black hole X-ray binary, whose dynamical parameters, namely the black hole mass, the inclination angle and the source distance, have been estimated recently. \emph{Insight}-HXMT have observed its entire outburst from March 14th, 2018. In this work, we attempted to estimate the spin parameter~$a_*$, using the continuum-fitting method and applying a fully-relativistic thin disk model to the soft-state spectra obtained by \emph{Insight}-HXMT. It is well know that $a_*$ is strongly dependent on three dynamical parameters in this method, and we have examined two sets of parameters. Adopting our preferred parameters: $M$ = $8.48^{+0.79}_{-0.72}~M_\odot$, $i=63^\circ\pm3^\circ$ and $D=2.96\pm0.33$ kpc, we found a slowly-spinning black hole of $a_*=0.14 \pm 0.09$ ($1σ$), which give a prograde spin parameter as majority of other systems show. While it is also possible for the black hole to have a retrograde spin (less than 0) if different dynamical parameters are taken.
Sraffa come “classico”: un esercizio congetturale

Subjects: SECS-P/01 Economia politica

description: La congettura che qui si propone è che in Produzione di merci Sraffa abbia inteso ripristinare il programma analitico, proprio degli economisti classici, di una teoria del valore-lavoro, superando il fallimento provocato dalla esplicita considerazione dei beni-capitali che ha reso impossibile la “riduzione” dei prezzi di produzione a valori-lavoro mediante misura del “lavoro morto” in essi contenuto. La congettura è condotta in tre momenti successivi. Anzitutto si ricostruisce il paradigma del valore-lavoro dei classici per mostrare come esso fosse rigorosamente esatto nel caso di una produzione “a solo lavoro”. In seguito si mostra come Sraffa avrebbe potuto operare per fondare un’analisi altrettanto rigorosa del valore-lavoro nonostante la presenza dei beni-capitali sulla base del punto di vista del prodotto netto complessivo per imputare al valore monetario di questo il solo “lavoro vivo” (equazione di neo-valore). Infine si suggerisce che Sraffa potrebbe essersi mosso proprio nella direzione di cui sopra, come sembrano alludere i suoi appunti di lavoro che progressivamente vengono alla luce. La conclusione della congettura è che, comunque giudicasse Sraffa (cosa che, al momento, è argomento opinabile), Produzione di merci può essere letta anche come la diretta prosecuzione della teoria del valore-lavoro degli economisti classici che risolve la difficoltà provocata dalla presenza dei beni-capitali impossibili a ridursi rigorosamente a quantità di “lavoro morto”.

description: A fast and exact algorithm is developed for the spin +-2 spherical harmonics transforms on equi-angular pixelizations on the sphere. It is based on the Driscoll and Healy fast scalar spherical harmonics transform. The theoretical exactness of the transform relies on a sampling theorem. The associated asymptotic complexity is of order O(L^2 log^2_2(L)), where 2L stands for the square-root of the number of sampling points on the sphere, also setting a band limit L for the spin +-2 functions considered. The algorithm is presented as an alternative to existing fast algorithms with an asymptotic complexity of order O(L^3) on other pixelizations. We also illustrate these generic developments through their application in cosmology, for the analysis of the cosmic microwave background (CMB) polarization data.

Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s}$ = 13 TeV $pp$ collisions with the ATLAS detector
Creators: name: ATLAS Collaboration

description: A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W$, $Z$, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically decaying $Z$ boson. The analyzed dataset corresponds to an integrated luminosity of 139 fb$^{-1}$ of proton-proton collision data produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s}$ = 13 TeV and collected by the ATLAS experiment between 2015 and 2018. The data are found to be consistent with predictions from the Standard Model. The results are interpreted as limits at 95% confidence level on model-independent cross sections for processes beyond the Standard Model. Limits are also set on the production of charginos and neutralinos for a Minimal Supersymmetric Standard Model with an approximate $B$-$L$ symmetry. Charginos and neutralinos with masses between 100 GeV and 1100 GeV are excluded depending on the assumed decay branching fractions into a lepton (electron, muon, or $τ$-lepton) plus a boson ($W$, $Z$, or Higgs).

Subjects: SECS-P/01 Economia politica

description: This paper presents a New Economic Geography model with distortionary taxation and endogenized trade costs. Tax revenues finance a public good, infrastructure. We show that the introduction of costly public investment in infrastructure increases agglomerative tendencies. With
respect to the regions' sizes, in the periphery, the price-index for manufacturing goods decreases, whereas for the core, the price-index is rather high since the distortionary effect of taxes dominates. 'Free riding' ¡ or, in terms of regional policy, externally funded infrastructure investment; is beneficial for the periphery, which can devote all its tax revenue to local
demand support, generating a positive home market effect and driving the catch-up process.

description: Countries in Southern Africa have engaged in a variety of trade liberalization initiatives. For example, South Africa and the European Union (EU) negotiated a free trade agreement (FTA) in 1999. The EU unilaterally opened its markets to the least developing countries, which includes some of the countries in the region, in 2001 under its “Everything But Arms” (EBA) initiative. Although not formally established, countries in the region have discussed a SADC FTA. In this paper, we use a multi-country, computable general equilibrium (CGE) model to analyze the impact of trade liberalization on countries, sectors, and factor. To focus on trade flows among countries in Southern Africa, the model includes seven countries in the region (South Africa, Botswana, Malawi, Mozambique, Tanzania, Zambia, and Zimbabwe), the rest of SADC, the rest of Sub-Saharan Africa, and five other aggregate regions (the EU, High-Income Asia, Low-Income Asia, North America, and the rest of the world). First, we analyze the FTA between South Africa and the EU. Then, we consider how the rest of Southern Africa might respond: (1) by enforcing a SADC FTA; (2) by exploiting advantages of unilateral access to the EU in addition to a SADC FTA; and (3) by entering an FTA with the EU and other SADC countries. We find that trade creation dominates trade diversion for the region under all FTA arrangements. Some SADC economies are slightly hurt by the FTA between the EU and South Africa while others slightly gain. Overall, the agreement is not a beggar thy neighbor policy. Unilateral access to the EU is more beneficial, in terms of real GDP and real absorption, for SADC countries than a SADC FTA. However, reciprocal reforms, under an EU-SADC FTA dominate unilateral access to the EU because they require more structural adjustment. Finally, we find that South Africa is not large enough to serve as a growth pole for the region. Access to EU markets provides substantially bigger gains for the other SADC countries than access to South Africa.

description: With the aid of an intertemporal, multi-region general equilibrium model, we study issues of agricultural trade liberalization, growth and capital accumulation in the context of a world economy moving towards a multi-polar structure. We specifically focus on Turkey, the European Union, the Middle East, and the Economies in Transition; and study alternative scenarios of formation of customs unions and increased trade orientation. The model is based on intertemporal general equilibrium theory with Ramsey-type dynamics. The world economy is fully endogenized within a 9-region specification, with Turkey, EU, Middle East and the Transition Economies constituting as one of the indigenous regions. A key feature of the model is its explicit recognition of both the commodity and foreign capital flows across regions in an endogenous setting, and its explicit portrayal of the out-of-steady state dynamics under an intertemporal optimization framework. We explore the short- versus the long-run economic impacts of alternative trade and investment policies on agricultural production, foreign trade, resource allocation, accumulation, consumer welfare, and income distribution in the regions of analysis. Our results reveal significant gains from increased bilateral trade between the identified regions, and further underscore the crucial importance of financing commodity trade deficits in sustaining the accumulation patterns.

description: Measuring the abundance of organisms is essential to provide information to ecology and biodiversity conservation. Hardly ever, the probability of detecting an animal during a survey is near one. Overlooking this observational process can lead to biased estimates of population size and vital rates. In this study, through Bayesian modeling, I evaluated the effects of temperature, precipitation, wind, humidity, and phenology in determining changes in the detection probability of the common wall lizard, for which studies on the factors determining detection probability are currently not available. Additionally, I tested for two possible interactions: date-temperature and date-humidity, in order to assess if the relationships of these variables with detection probability vary through the sampling season. Detection probability was highest earlier in the season (April) and between 24 and 28 degrees. Rainfall during the survey showed a negative effect on detection probability. In contrast, cumulative precipitation in the 24 hours before the survey showed a positive relationship, indicating that lizards are easier to detect in surveys after rainy days. Furthermore, date and temperature showed a positive interaction, indicating that the relationship between detectability and temperature changed over the sampling season. Date and humidity showed a negative interaction: late in the sampling season, detectability was higher with lower humidity, however, this relationship was not found in the early season. Future studies can consider multiple sites to evaluate the extent of variation in the drivers of detection probability and to assess the factors related to abundance.

description: The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories have been developed to tackle the issue. Partial wave dynamics is the systematic tool to decode the underlying physics and reveal the properties of those resonances. It is extremely powerful and helpful for our understanding of the non-perturbative regime, especially when dispersion techniques are utilized simultaneously. Recently, plenty of exotic/ordinary hadrons have been reported by experiment collaborations, e.g. LHCb, Belle, and BESIII, etc.. In this review, we summarize the recent progress on the applications of partial wave dynamics combined with chiral effective field theories and dispersion relations, on related topics, with emphasis on $ππ$, $πK$, $πN$ and $\bar{K}N$ scatterings.

description: The objective of this paper is to present a survey of trade issues in agriculture from the perspective of developing countries. Developing countries are a large percentage of the World Trade Organization (WTO) membership, and agriculture is critical for their economic growth, poverty alleviation, food security, and environmental sustainability. First, this paper identifies trends in production, consumption, and trade of food and agriculture over the last four decades. Some of the significant developments food and agricultural trade is the emergence of oilseeds and fruits and vegetables, which are becoming the main exports from developing countries, replacing traditional exports such as sugar, coffee and cocoa. The trends show also a worsening of developing countries' net trade position due in part to income growth and population pressures, but also to economic policies in general, and trade policies in particular, both in developing and industrialized countries. Second, this paper focuses on some of the main development issues linked to the WTO agricultural negotiations. The objective is to align the different legal components and subcomponents of the negotiations under the Agreement on Agriculture, with developing countries' final objectives of sustainable economic growth, poverty alleviation, and food security. This paper concludes that the problems for developing countries are not mainly legal constraints under the AoA, but the lack of financial and human resources and institutional capabilities. To link negotiations to their development goals, developing countries must consider the issue of funding. Finally, developing countries, most of which have embarked in unilateral liberalization over the last decade, should ask significant down-payments in the reduction of the higher levels of protection and subsidies in industrialized countries.
Study abroad as contested space of global and local discourses : Japanese male students’ study abroad experiences in Vancouver

description: This qualitative study examined Japanese students' study abroad experiences in Vancouver. I conceptually framed study abroad as contested space where global and local (national) discourses converge and shape these students' experience. Based on this conceptual understanding of study abroad, I reviewed three global and local (national) discourses that were relevant to Japanese students' study abroad experiences: neocolonialism, "internationalization," and nihonjinron (discussions of Japanese uniqueness). These three discourses were monitored throughout Japanese students' study abroad experiences to examine how they would shape these students' experiences and how these students would negotiate to construct their experiences in the midst of these discourses. Furthermore, as the sub-theme of the study, I examined Japanese students' study abroad experiences in terms of Edward Said's (1995) hope for the creation of non-essentialist, nondominative, and non-coercive form of knowledge. I examined the possibility of study abroad experience as a transformative educational experience that helps students decipher the hegemonic and ideological limitations on their knowledge of "race" and nation. From May to November 1999,1 conducted participatory observations and semi-structured interviews with seventeen Japanese male students who had resided in Vancouver for more than six months. The data suggested that the three discourses of necolonialism, "internationalization," and nihonjinron (discussions of Japanese uniqueness) were manifested to shape the Japanese students' experiences. I argued that as a consequence of the manifestation of these three discourses, the Japanese students rendered "Canadians" into the "Other." Furthermore, this bi-polar and essentialist understanding of "Self and "Others" led to their objectification and commodification of "Canadians" as a medium for "internationalizing" themselves. I conclude that study abroad experiences in Vancouver was not effective in helping the Japanese students go beyond the global (neocolonial) and local (national) ideological discourses. Rather, the study suggested that the Japanese students' study abroad experiences reinforced their preconceived sense of human difference, leading them to view "Canadians" as discontinuous from "us," which enabled them to commodity them merely as a medium for "internationalizing" themselves. Given the findings of the study, I suggest for employing a postcolonial perspective in the examination of foreign students' study abroad experience. I also call for critical re-evaluation of study abroad experiences of foreign students, in particular, Japanese students and for the attempt to turn study abroad into a transformative learning opportunity that helps students move beyond hegemonic imperial discourses of "race" and nation.
