Purpose
This study aims to provide a detailed characterization of Argentinean exporting wineries using a new rich firm-level data set to understand how capabilities and business strategies differ ...among firms with different levels of involvement in the export market.
Design/methodology/approach
A survey was distributed among all wineries along all wine regions of Argentina; the 45-min questionnaire was answered by 230 wineries, a representative sample with a response rate of 26.3% of the total population of Argentinean wineries. The survey assessed the interaction between wineries’ dynamics and characteristics and their participation in export markets. In the comparative analysis, the results are presented by dividing the sample into four categories according to the export intensity of the wineries.
Findings
High-intensity exporting wineries in Argentina differ from other Argentinean wineries in several dimensions. In particular, the most internationalized Argentinean wineries are the most endowed with higher capabilities; they follow a specific business model emphasizing product differentiation, quality upgrading, brand building and the development of distribution channels. Exporting wineries from Argentina adopt business practices that differ from those that prevail among wineries that only target the domestic market. They have developed firm capabilities such as human capital and technology to play a critical role in quality upgrading for their participation in global wine markets.
Originality/value
To the best of the authors’ knowledge, this paper is the first to study the Argentinean exporting wineries using a firm-level sizeable representative sample.
PurposeUsing the behavioural perspective as a theoretical complement of rational models, this paper examines factors that influence the decision of producing organic ...wines.Design/methodology/approachBased on a quantitative analysis of 687 wineries belonging to Denomination of Origin in Spain, the authors empirically examine the sequential relationships between manager's personality and winery and institutional level factors, on organic wine production activity and winery export performance.FindingsThis paper investigates the direct and indirect sequential relationships between wineries' factors including an organic production activity and two dimensions of export performance, namely: volume-based and value-based performance. The results of a sequential model provide evidence that openness to experience, a manager's personality trait, has a positive causal relationship with organic wine production.Practical implicationsThis paper offers richer insights into the factors leading wine production managers to change from conventional to organic production methods. Specifically, the study shows that wine production managers are susceptible to make decisions to whether produce organic wine or not that may not be consistent with the current theoretical models based on economic efficiency (i.e. comparing costs and benefits). Instead, these decisions are, in part, based on their personality traits. Future research could study how the functional attribute affects the willingness to produce organic wines.Originality/valueThis study contributes to a new strategic implication of organic wine production activity and export performance linkage in behavioural and traditional theoretical perspectives. These findings are valuable for policy makers in the wine sector, as they can better inform and guide policies directed to identify organic production support programs.
There are arguably potential wage gains from exports in developing countries. Export markets bring about opportunities for firms and successful exporting firms translate some of the benefits of ...exports to workers via employment and wage premia. Using comparable data for 61 developing and low‐income countries, we document the prevalence of the export wage premia worldwide. With an extensive literature review, we identify four major drivers of the wage premia: exporting firms hire more skilled workers, utilize more sophisticated machines, buy higher quality material inputs and are more productive than non‐exporting firms. Our empirical analysis confirms the worldwide prevalence of these mechanisms and, furthermore, establishes a strong link to the estimated wage premia.

The concentration of greenhouse gases in the atmosphere plays an important role in the radiative effects in the Earth's climate system. Therefore, it is crucial to increase the number of atmospheric ...observations in order to quantify the natural sinks and emission sources. We report in this paper the development of a new compact lightweight spectrometer (1.8 kg) called AMULSE based on near infrared laser technology at 2.04 µm coupled to a 6-m open-path multipass cell. The measurements were made using the Wavelength Modulation Spectroscopy (WMS) technique and the spectrometer is hence dedicated to in situ measuring the vertical profiles of the CO₂ at high precision levels (σ
= 0.96 ppm in 1 s integration time (1σ)) and with high temporal/spatial resolution (1 Hz/5 m) using meteorological balloons. The instrument is compact, robust, cost-effective, fully autonomous, has low-power consumption, a non-intrusive probe and is plug & play. It was first calibrated and validated in the laboratory and then used for 17 successful flights up to 10 km altitude in the region Champagne-Ardenne, France in 2014. A rate of 100% of instrument recovery was validated due to the pre-localization prediction of the Météo-France based on the flight simulation software.

How do tariffs impact gender inequality? Using harmonized household survey and tariff data from 54 low- and middle income countries, this paper shows that protectionism has an anti-female bias. On ...average, tariffs repress the real incomes of female headed households by 0.6 percentage points relative to that of male headed ones. Female headed households bear the brunt of tariffs because they derive a smaller share of their income from and spend a larger share of their budget on agricultural products, which are usually subject to high tariffs in developing countries. Consistent with this explanation, the anti-female bias is stronger in countries where female-headed households are underrepresented in agricultural production, are more reliant on remittances, and spend a comparatively larger share of their budgets on food than male-headed ones.

This paper reports on experimental and theoretical investigations of atypical temperature-dependent photoluminescence properties of multi-stacked InAs quantum dots in close proximity to InGaAs ...strain-relief underlying quantum well. The InAs/InGaAs/GaAs QD heterostructure was grown by solid-source molecular beam epitaxy (SS-MBE) and investigated via photoluminescence (PL), spectroscopic ellipsometry (SE), and picosecond time-resolved photoluminescence. Distinctive double-emission peaks are observed in the PL spectra of the sample. From the excitation power-dependent and temperature-dependent PL measurements, these emission peaks are associated with the ground-state transition from InAs QDs with two different size populations. Luminescence measurements were carried out as function of temperature in the range of 10–300 K by the PL technique. The low temperature PL has shown an abnormal emission which appeared at the low energy side and is attributed to the recombination through the deep levels. The PL peak energy presents an anomalous behavior as a result of the competition process between localized and delocalized carriers. We propose the localized-state ensemble model to explain the usual photoluminescence behaviors. The quantitative study shows that the quantum well continuum states act as a transit channel for the redistribution of thermally activated carriers. We have determined the localization depth and its effect on the application of the investigated heterostructure for photovoltaic cells. The model gives an overview to a possible amelioration of the InAs/InGaAs/GaAs QDs SCs properties based on the theoretical calculations.
Bacterial pathogens often deliver effectors into host cells using type 3 secretion systems (T3SS), the extremity of which forms a translocon that perforates the host plasma membrane. The T3SS encoded ...by Salmonella pathogenicity island 1 (SPI-1) is genetically associated with an acyl carrier protein, IacP, whose role has remained enigmatic. In this study, using tandem affinity purification, we identify a direct protein-protein interaction between IacP and the translocon protein SipB. We show, by mass spectrometry and radiolabelling, that SipB is acylated, which provides evidence for a modification of the translocon that has not been described before. A unique and conserved cysteine residue of SipB is identified as crucial for this modification. Although acylation of SipB was not essential to virulence, we show that this posttranslational modification promoted SipB insertion into host-cell membranes and pore-forming activity linked to the SPI-1 T3SS. Cooccurrence of acyl carrier and translocon proteins in several γ- and β-proteobacteria suggests that acylation of the translocon is conserved in these other pathogenic bacteria. These results also indicate that acyl carrier proteins, known for their involvement in metabolic pathways, have also evolved as cofactors of new bacterial protein lipidation pathways.

IFMIF-DONES is a facility under construction in Granada, whose main goal is the validation and characterization of materials under a fusion prototypic irradiation field. This field is created by the ...interaction of a high energy intense continuous deuteron beam and a flowing liquid lithium target. The requirements imposed on the beam at the interaction point are a complex trade-off among the scientific experimental needs for the materials irradiation defined at the top-level requirements (20 dpa in a volume of 0.3 dm3 and 50 dpa in 0.1 dm3), and the technical constraints of several systems such as the Accelerator Systems, the Lithium Systems, and the Test Systems. Recent simulations with the initial definition of beam-on-target requirements showed the necessity of redefining them in order to fulfill the irradiation needs. This contribution will address the main challenges to gather the inputs for the definition and reassessment of the beam-on-target requirements. A comparison detailing the main changes compared to the previous ones will be given, together with a short overview of the studies ongoing by different systems to analyze the impact of each beam-on-target requirements on the performance of the whole facility.

We report on the generation of photon pairs at 1550 nm from free-standing epitaxially grown self-assisted micrometre long GaAs nanowires. The efficiency of the spontaneous parametric down-conversion ...process has a rate of 320 GHz/Wm normalized to the transmission of the setup, the pump intensity, and the volume of the nanostructure. GaAs is a high index dielectric that can support electromagnetic Mie modes, therefore we model how shorter nanowires could improve the second-harmonic signal and we found that sub-micro long nanowires (600 nm length and 250 nm diameter) can support quality factors up to 15 at the pump wavelength (780 nm). We anticipate that the near field enhancement compared to micrometre long nanowires will boost the second-harmonic generation and, correspondingly, the biphoton rate efficiency.
