Instrumento para medir la felicidad en la provincia de Camaná - Arequipa, Perú
No full textEn la actualidad, el bienestar no puede ser medido solo en términos de riqueza, por lo que se
han incorporado los aspectos subjetivos. Para su medición, la Organización para la
Cooperación y el Desarrollo Económicos (OCDE) ha establecido lineamientos que permiten,
a los países, hacer comparables los resultados con el fin de desarrollar políticas públicas
eficaces. En el Perú, no se encontró evidencia de que exista una medición de bienestar
subjetivo por parte del Estado para este fin. Por ello, el propósito de esta investigación es
determinar el nivel de bienestar subjetivo de los pobladores de la provincia de Camaná, que
permita desarrollar propuestas en beneficio de la población. Para lograr este objetivo, la
presente investigación es de carácter transversal, no experimental, descriptivo y con un
enfoque cuantitativo. De una población de 46,897 habitantes, se seleccionó una muestra de
226 personas entre hombres y mujeres mayores de 18 años, quienes fueron encuestadas. El
instrumento utilizado para la investigación fue el cuestionario de Bienestar Autorreportado
(BIARE), elaborado por el Instituto Nacional de Estadística y Geografía de México (INEGI),
basado en los lineamientos dictados por la OCDE. Con este instrumento se pudo obtener
información que permitió identificar las variables que predominan en las personas que

In Peru, no evidence has been found of the existence of subjective well-being measurement

determine the subjective well-being level of the inhabitants of the Camana province and
develop a proposal that will benefit the population. To achieve this objective, the present
research is of a transversal nature, not experimental, it is descriptive with a quantity
approach. From a population of 46 897 habitants, a sample of 226 people was selected among
men and women over 18 years of age, who were surveyed. The instrument used for this
investigation was the self-reported well-being (BIARE) survey, developed by the National
Institute of Statistics and Geography of Mexico (INEGI), based on the OCDE’s parameters.
With this instrument we were able to obtain information that allowed us to identify the
variables that prevail in the people that showed low levels of life satisfaction to elaborate
recommendations to help the local government develop projects for its betterment

O mal-estar dos desempregados: uma medição do efeito do desemprego individual e contextual sobre a satisfação com a vida no México
No full textThis article presents new evidence on the relationship between unemployment and subjective well-being in Mexico. Using data from the Self-Reported Well-Being Survey and a happiness equation, differences in well-being derived from employment status and the context of the local labor market are analyzed. The results reveal a deterioration in life satisfaction associated with unemployment, with this reduction being more than twice that caused by income loss. Additionally, an increase in the unemployment rate reduces well-being, particularly among people with basic education. However, in regions with high informality, subjective wellbeing is not significantly affected by unemployment.Este artículo presenta nueva evidencia sobre la relación entre el desempleo y el bienestar subjetivo en México. A partir de datos de la Encuesta de Bienestar Autorreportado y utilizando una ecuación de felicidad, se analizan las diferencias en bienestar derivadas de la condición laboral y el contexto del mercado laboral local. Los resultados revelan un deterioro en la satisfacción con la vida asociado al desempleo, siendo esta reducción más del doble que la causada por la disminución de ingresos. Asimismo, el aumento de la tasa de desempleo reduce el bienestar, particularmente entre personas con educación básica. No obstante, en regiones de alta informalidad, el bienestar subjetivo no se ve afectado de manera significativa por el desempleo.Este artigo apresenta novas evidências sobre a relação entre o desemprego e o bem-estar subjetivo no México.

Os resultados revelam um declínio na satisfação com a vida associado ao desemprego, sendo essa redução mais que o dobro da causada pela perda de renda. Além disso, o aumento da taxa de desemprego reduz o bem-estar, particularmente entre pessoas com educação básica. No entanto, em regiões de alta informalidade, o bem-estar subjetivo não é significativamente afetado pelo desemprego

TAO Conceptual Design Report: A Precision Measurement of the Reactor Antineutrino Spectrum with Sub-percent Energy Resolution
No full textThe Taishan Antineutrino Observatory (TAO, also known as JUNO-TAO) is a
satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). A
ton-level liquid scintillator detector will be placed at about 30 m from a core
of the Taishan Nuclear Power Plant. The reactor antineutrino spectrum will be
measured with sub-percent energy resolution, to provide a reference spectrum
for future reactor neutrino experiments, and to provide a benchmark measurement
to test nuclear databases. A spherical acrylic vessel containing 2.8 ton
gadolinium-doped liquid scintillator will be viewed by 10 m^2 Silicon
Photomultipliers (SiPMs) of >50% photon detection efficiency with almost full
coverage. The photoelectron yield is about 4500 per MeV, an order higher than
any existing large-scale liquid scintillator detectors. The detector operates
at -50 degree C to lower the dark noise of SiPMs to an acceptable level. The
detector will measure about 2000 reactor antineutrinos per day, and is designed
to be well shielded from cosmogenic backgrounds and ambient radioactivities to
have about 10% background-to-signal ratio. The experiment is expected to start
operation in 2022

No full textThe Jiangmen Underground Neutrino Observatory (JUNO) features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector. Some of JUNO's features make it an excellent location for 8B solar neutrino measurements, such as its low-energy threshold, high energy resolution compared with water Cherenkov detectors, and much larger target mass compared with previous liquid scintillator detectors. In this paper, we present a comprehensive assessment of JUNO's potential for detecting 8B solar neutrinos via the neutrino-electron elastic scattering process. A reduced 2 MeV threshold for the recoil electron energy is found to be achievable, assuming that the intrinsic radioactive background 238U and 232Th in the liquid scintillator can be controlled to 10-17g/g. With ten years of data acquisition, approximately 60,000 signal and 30,000 background events are expected. This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter, which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework. If Δm221= 4.8 × 10-5(7.5 × 10-5) eV, JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3σ (2σ) level by measuring the non-zero signal rate variation with respect to the solar zenith angle. Moreover, JUNO can simultaneously measure Δm221using 8B solar neutrinos to a precision of 20% or better, depending on the central value, and to sub-percent precision using reactor antineutrinos. A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Δm221reported by solar neutrino experiments and the KamLAND experiment
TAO Conceptual Design Report: A Precision Measurement of the Reactor Antineutrino Spectrum with Sub-percent Energy Resolution
No full textInternational audienceThe Taishan Antineutrino Observatory (TAO, also known as JUNO-TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). A ton-level liquid scintillator detector will be placed at about 30 m from a core of the Taishan Nuclear Power Plant. The reactor antineutrino spectrum will be measured with sub-percent energy resolution, to provide a reference spectrum for future reactor neutrino experiments, and to provide a benchmark measurement to test nuclear databases. A spherical acrylic vessel containing 2.8 ton gadolinium-doped liquid scintillator will be viewed by 10 m^2 Silicon Photomultipliers (SiPMs) of >50% photon detection efficiency with almost full coverage. The photoelectron yield is about 4500 per MeV, an order higher than any existing large-scale liquid scintillator detectors. The detector operates at -50 degree C to lower the dark noise of SiPMs to an acceptable level. The detector will measure about 2000 reactor antineutrinos per day, and is designed to be well shielded from cosmogenic backgrounds and ambient radioactivities to have about 10% background-to-signal ratio. The experiment is expected to start operation in 2022
Feasibility and physics potential of detecting B solar neutrinos at JUNO
No full textInternational audienceThe Jiangmen Underground Neutrino Observatory (JUNO) features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector. Some of JUNO's features make it an excellent location for B solar neutrino measurements, such as its low-energy threshold, high energy resolution compared with water Cherenkov detectors, and much larger target mass compared with previous liquid scintillator detectors. In this paper, we present a comprehensive assessment of JUNO's potential for detecting B solar neutrinos via the neutrino-electron elastic scattering process. A reduced 2 MeV threshold for the recoil electron energy is found to be achievable, assuming that the intrinsic radioactive background U and Th in the liquid scintillator can be controlled to 10 g/g. With ten years of data acquisition, approximately 60,000 signal and 30,000 background events are expected. This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter, which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework. If eV , JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3 (2 ) level by measuring the non-zero signal rate variation with respect to the solar zenith angle. Moreover, JUNO can simultaneously measure using B solar neutrinos to a precision of 20% or better, depending on the central value, and to sub-percent precision using reactor antineutrinos. A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of reported by solar neutrino experiments and the KamLAND experiment
