Abstract. Crop phenology exerts measurable impacts on soil surface
properties, biophysical processes and climate feedbacks, particularly at
local or regional scales. Nevertheless, the response of surface biophysical
processes to climate feedbacks as affected by sowing date in winter wheat
croplands has been overlooked, especially during winter dormancy. The
dynamics of leaf area index (LAI), surface energy balance and canopy
temperature (Tc) were simulated by a modified SiBcrop (Simple Biosphere) model under two
sowing date scenarios (early sowing, EP; late sowing, LP) at 10 stations in
the North China Plain. The results showed that the SiBcrop model with a modified
crop phenology scheme well simulated the seasonal dynamic of LAI, Tc,
phenology and surface heat fluxes. An earlier sowing date had a higher LAI with
earlier development than a later sowing date. But the response of Tc to
the sowing date exhibited opposite patterns during the dormancy and active-growth periods: EP led to higher Tc (0.05 K) than LP in the dormancy
period and lower Tc (−0.2 K) in the growth period. The highest difference
(0.6 K) between EP and LP happened at the time when wheat was sown in EP but
was not in LP. The higher LAI captured more net radiation with a warming
effect but partitioned more energy into latent heat flux with cooling. The
climate feedback of the sowing date, which was more obvious in winter in the
northern areas and in the growing period in the southern areas, was
determined by the relative contributions of the albedo radiative process and
partitioning non-radiative process. The study highlights the surface
biophysical process of land management in modulating climate.
A global climatology of the ocean surface during the Last Glacial Maximum mapped on a regular grid (GLOMAP)

Abstract. We present a climatology of the near-sea-surface temperature (NSST) anomaly and the sea-ice extent during the Last Glacial Maximum (LGM, 23 000–19 000 years before present) mapped on a global regular 1∘×1∘ grid. It is an extension of the Glacial Atlantic Ocean Mapping (GLAMAP) reconstruction of the Atlantic NSST based on the faunal and floral assemblage data of the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) project and several recent estimates of the LGM sea-ice extent. Such a gridded climatology is highly useful for the visualization of the LGM climate, calculation of global and regional NSST averages, and estimation of the equilibrium climate sensitivity, as well as a boundary condition for atmospheric general circulation models. The gridding of the sparse NSST reconstruction was done in an optimal way using the Data-Interpolating Variational Analysis (DIVA) software, which takes into account the uncertainty in the reconstruction and includes the calculation of an error field. The resulting Glacial Ocean Map (GLOMAP) confirms the previous findings by the MARGO project regarding longitudinal and meridional NSST differences that were greater than today in all oceans. Taken at face value, the estimated global and tropical cooling would imply an equilibrium climate sensitivity at the lower end of the currently accepted range. However, because of anticipated changes in the seasonality and thermal structure of the upper ocean during the LGM as well as uneven spatial sampling, the estimated cooling and implied climate sensitivity are likely to be biased towards lower values.
A spectral approach to estimating the timescale-dependent uncertainty of paleoclimate records – Part 2: Application and interpretation
Authors: Dolman Andrew M. , Kunz Torben , Groeneveld Jeroen , Laepple Thomas 
Published: April 2021

Abstract. Proxy climate records are an invaluable source of information about the earth's climate prior to the instrumental record. The temporal and spatial coverage of records continues to increase; however, these records of past climate are associated with significant uncertainties due to non-climate processes that influence the recorded and measured proxy values. Generally, these uncertainties are timescale dependent and correlated in time. Accounting for structure in the errors is essential for providing realistic error estimates for smoothed or stacked records, detecting anomalies, and identifying trends, but this structure is seldom accounted for. In the first of these companion articles, we outlined a theoretical framework for handling proxy uncertainties by deriving the power spectrum of proxy error components from which it is possible to obtain timescale-dependent error estimates. Here in Part 2, we demonstrate the practical application of this theoretical framework using the example of marine sediment cores. We consider how to obtain estimates for the required parameters and give examples of the application of this approach for typical marine sediment proxy records. Our new approach of estimating and providing timescale-dependent proxy errors overcomes the limitations of simplistic single-value error estimates. We aim to provide the conceptual basis for a more quantitative use of paleo-records for applications such as model–data comparison, regional and global synthesis of past climate states, and data assimilation.

Published: April 2021

El presente escrito reflexiona, desde Uruguay, sobre el Choque como dispositivo relacional y performático para ponerlo a funcionar en la vía pública. El Choque es una práctica corporal híbrida, donde confluyen diferentes ritmos que podemos nombrar como de raíz africana y que nos permite pensar y accionar en torno a los mandatos de masculinidad, los cuerpos normados, la captura del placer y la fiesta como potencia colectiva. El texto aborda algunas ideas iniciales sobre estos temas desde un cuerpo que suda, grita y se manifiesta en palabras. Con la convicción de que es necesario una búsqueda de la potencia de lo común y la relevancia que la danza puede tener en estos procesos de germinación de otras corporalidades.

ABCDEFG (1994) do coreógrafo, bailarino e realizador Russell Dumas é um filme de um dueto dançado. Este filme é pensado aqui como um projecto de corporalidade autónomo. Uma exposição sobre particularidades na obra de Russell Dumas determinantes para a realização do filme em causa, a saber — a do trabalho do bailarino; a da interacção dos bailarinos e dos bailarinos com o coreógrafo; e a da relação entre o dueto desempenhado e a realização do filme —, permite uma análise sobre a especificidade própria da relação que o observador pode estabelecer com o objecto/acontecimento ABCDEFG (1994).
Pretende-se detectar zonas de indeterminação e indiscernabilidade que permitem, no fluxo de inferências de cada percepção, situarmo-nos num território de experimentação da permanente e plástica reconstrução do espaço topológico do corpo.

The “Aesthetics of Existence” in the Last Foucault: Art as a Model of Self-Invention
Authors: Ratiu Dan Eugen 
Published: April 2021

Abstract
This article discusses the “aesthetics of existence” developed by Foucault in the late “ethical” stage of his work, aiming to clarify its complex significance through its relationships with ethics, critique, and, in particular, art as a model of self-invention. The main claims are that aesthetics of existence is a new type of self-formation molded by technologies inspired not only by the ancient ethical self-formation but also by modern art understood as creative self-production; thus, aesthetics of existence is an active form of aesthetic education, in the particular sense of an ontological self-formation. To argue these claims, the author advances a line of analysis alternative to typical readings, which see it as related exclusively to the ancient “art of living” or its modern revival in the Nietzschean project of self-fashioning. The focus is instead on the Baudelairean and Kantian roots of Foucault’s work—modernity as a critical attitude and the transgressive art of the self of the dandy—as keys to understand the reframing by him of the art of living into a modern aesthetics of existence. This appears as a critical-transgressive invention of the self, which could contribute to constituting new subjectivities and alternative norms for the entire social body.

Introduction: Preparing future mothers for the birth of newborn is an important part of birth preparedness counseling and one of major responsibility of health care provider.
Objectives: The aim of this study was to assess awareness of antenatal mothers for birth preparedness and complication readiness and find association of awareness with socio demographic variables.
Methodology: This descriptive study was conducted using cross sectional research design. Total 200 antenatal mothers were selected using the purposive sampling technique who was attending antenatal OPD at Pt. B. D. Sharma PGIMS, Rohtak, and Haryana, India. Data was collected by using semi structured questionnaire.
Result: The majority of antenatal mothers were belongs to age group of 18-25 years and were secondary level educated. Most of antenatal mothers (54%) had poor knowledge of birth preparedness and complication readiness. Chi square test showed a significant association among awareness level of antenatal mothers with age (0.002*), educational level of self (0.003*) and husband (0.000*), gravida (0.03*), time to reach to health care facility (0.015*) and mode of transportation in emergency (0.005*). Odd ratios showed that antenatal mother who did not done their antenatal register had a 0.81 times more chances for less awareness than registered mothers.
Conclusion: Awareness of antenatal mothers for birth preparedness and complication readiness was poor. There are various hindering factors which must be explored for betterment of maternal outcome and success of birth preparedness and complication readiness programs.

Published: April 2021

Introduction: In developing countries, malnutrition is a major public health concern. Infant and young child feeding (IYCF) is a set of well-known, common and scientific recommendations for optimal feeding of newborn and children under two years of age including initiation of breastfeeding within one hour of birth, exclusive breastfeeding for first six months, after which appropriate and safe complementary foods should be given along with continuing breastfeeding up to two years of age and beyond.
AIM: To find out the epidemiological association of IYCF practices in rural area of Bareilly district.
Material and methods: The study was conducted in rural area of Bareilly, Uttar Pradesh from January 2020 to February 2020 in children aged ≤ 1 year.
Results: There were significant associations (p< 0.05) between pre-lacteal feed and age of mother, sex of child, education of father and religion.
Conclusion: There have been considerable developments in the status of IYCF practices in Bareilly. However exclusive breastfeeding was not fully practiced. Hence promotion of IYCF is needed.

A future agenda for environmental restorative justice?
The challenges of developing meaningful environmental regulation to protect communities and the environment have never been greater. Environmental regulators are regularly criticised for failing to act hard and consistently, in turn leading to demands for harsher punishments and more rigorous enforcement. Whilst acknowledging the need for strong enforcement to address wantonly destructive practices threatening communities and ecosystems, we argue that restorative approaches have an important role. This article explores a future agenda for environmental restorative justice through (1) situating it within existing scholarly and practice-based environmental regulation traditions; (2) identifying key elements and (3) raising particular theoretical and practical challenges. Overall, our vision for environmental restorative justice is that its practices can permeate the entire regulatory spectrum, going far beyond restorative justice conferences within enforcement proceedings. We see it as a shared and inclusive vision that seeks to integrate, hybridise and build broader ownership for environmental restorative justice throughout existing regulatory practices and institutions, rather than creating parallel structures or paradigms.
Why an atmosphere of transhumanism undermines green restorative justice concepts and tenets

Why an atmosphere of transhumanism undermines green restorative justice concepts and tenets
Arising from the notions of green criminology and green victimology, green restorative justice can be defined as a restorative justice focused on environmental harm. Harm in this case is understood as criminalised and non-criminalised, and as individual and collective behaviours damaging the ecosystems and the existence of human and non-human beings. Impacts of environmental harm affect health, economic, social and cultural dimensions, and will be experienced in the short, medium and long term. Within this framework, after linking restorative justice to green criminology and green victimology, I will argue that the current weight of the cultural and social movement of transhumanism constitutes an obstacle to the development of restorative justice in this field. The reason is that it fosters individual narcissism, together with the idea of an absence of limits in what is considered technological progress. This progress is seen as inevitable and good per se, and promotes the perception of a lack of social and moral accountability. This reasoning will lead to some final reflections on how restorative justice has to constantly reinvent itself in order to keep creating a critical and inclusive justice of ‘otherness’. By doing so, restorative justice must join the current interdisciplinary conversation on biopolitics and bioethics.
