Authors: Mao Qiushuo , Liu Xiaoguang , Li Yan , Jiang Yue , Sun Jialin 
Published: January 2021

AbstractTo improve UiO‐66’s adsorption capacity towards methylene blue (MB) of low concentrations, an efficient modulator, butyric acid, has been successfully employed to regulate its defect levels using a modulation method. The butyric acid regulated UiO‐66 has higher degree (6.08 %) of defects, larger mass loss (8.63 %) from 248 to 440 °C, lower BDC2−/Zr molar ratios (0.86) and higher specific surface area (1186 m2/g) than those (5.86 %, 6.98 %, 0.90, and 1024 m2/g, respectively) of the most studied acetic acid modulated one. Furthermore, its SEM images also show the near‐spherical shapes and the formation of many wrinkles/grooves on the outer rough surfaces. Hence when the concentration of MB is as low as 40 mg/L, it can still reach a higher adsorption capacity (143 mg/g) than the mostly studied acetic acid modulated one. The saturated adsorption capacity of UiO‐66 (Butyric acid) almost reaches 765 mg/g, much better than other adsorption materials. In comparison, the acetic acid regulated one shows slightly lower specific surface areas, less defective structures, smoother surface and more polyhedral shapes. It thus reaches a smaller adsorption capacity of about 97 mg/g despite in a rather short time (∼5 min). The underlying mechanism for the above different adsorption behaviors is also addressed. Overall, it is suggest that the butyric acid can significantly change the defect levels in UiO‐66 and thus improve its MB adsorption uptake.
Agroecology and Climate Change Adaptation: Farmers’ Experiences in the South African Lowveld
Authors: Zazu Cryton , Manderson Anri 
Published: January 2021

AbstractMotivated by interest to increase the resilience of smallholder farmers to adapt to climate change through uptake of agroecology, two community development organizations commissioned a project evaluation upon which this book chapter is written. The chapter discusses how smallholder farmers were experiencing implementing agroecology, trying to understand the reasons for adopting such an approach to farming. The chapter also explores and problematizes the relationship between trends in adoption of agroecology and the smallholder farmers’ awareness of climate change and adaptation. The chapter confirms that agronomic and income generation are the key reasons for adoption of agroecology. Most of the farmers reminisced about how their crop yields had declined and soils no longer producing enough to feed the family. Other motivating factors for uptake of agroecology included lack of employment, limited income sources, access to health organic foods, and medicinal value of herbs grown. The chapter further concluded that the correlation between adoption of agroecology and farmers’ awareness of it as a climate change adaptation measure is generally weak. Smallholder farmers adopted agroecology more for responding to issues of food security, than any conscious desire to adapt to climate change. Implications of this observation is that practitioners working with smallholder farmers need to rethink their approaches and design of interventions to integrate climate change education and learning, so that strong connections between the agroecological practices promoted and adaptation to climate change are made. Such an approach has potential to improve the sustainability and value of the agroecological practices adopted.
“Conservation Agriculture,” Possible Climate Change Adaptation Option in Taita Hills, Kenya
Authors: Motaroki Lilian , Ouma Gilbert , Kalele Dorcas 
Published: January 2021

AbstractThe vicious cycle of food insecurity in Kenya and Africa at large is partly attributed to the high reliance on rainfed agriculture, which makes production systems vulnerable to the adverse impacts of climate change and variability. Conservation agriculture (CA) has been disseminated as a climate-smart practice that operates on three main principles to realize the multiple benefits of making crop production systems more resilient to climate change impacts, enhancing food security, and providing environmental services, such as carbon sequestration. As a major source of livelihood in the Taita Hills, agriculture is constrained by climate change owing to its rainfed nature. The yield and environmental and economic benefits of CA make it a suitable alternative approach to sustainable agricultural intensification, which is fundamentally different from conventional approaches based on intensive tillage and often disrupts ecosystem functions. This chapter provides the rationale for enhancing the adoption of CA in the Taita Hills by evaluating the current challenges affecting crop production, the role of CA in addressing the challenges and its potential benefits, and the barriers that must be overcome in order to promote its wide-scale adoption. A number of constraints appear to hinder the wide-scale adoption of CA in the Taita Hills, including lack of awareness, tenure-related issues, and weak policy and institutional support. Addressing these constraints will help catalyze investments for upscaling CA in the Taita Hills, with potential for replication in other parts of the country.
Open topological recursion relations in genus 1 and integrable systems
Authors: Gomez Oscar Brauer , Buryak Alexandr 
Published: January 2021

AbstractThe paper is devoted to the open topological recursion relations in genus 1, which are partial differential equations that conjecturally control open Gromov-Witten invariants in genus 1. We find an explicit formula for any solution analogous to the Dijkgraaf-Witten formula for a descendent Gromov-Witten potential in genus 1. We then prove that at the approximation up to genus 1 the exponent of an open descendent potential satisfies a system of explicitly constructed linear evolutionary PDEs with one spatial variable.
Supersymmetric space-time symmetry breaking sources
Authors: Anderson Louise , Roberts Matthew M. 
Published: January 2021

Abstract
We construct new families of deformed supersymmetric field theories which break space-time symmetries but preserve half of the original supersymmetry. We do this by writing deformations as couplings to background multiplets. In many cases it is important to use the off-shell representation as auxiliary fields of the non-dynamical fields must be turned on to preserve supersymmetry. We also consider backgrounds which preserve some superconformal symmetry, finding scale-invariant field profiles, as well as $$ \mathcal{N} $$
N
= 2 theories on S3. We discuss how this is related to previous work on interface SCFTs and other holographic calculations.

Published: January 2021

AbstractAdults with major depressive disorder (MDD) with psychotic features (delusions and/or hallucinations) have more severe symptoms and a worse prognosis. Subclinical psychotic symptoms are more common in adolescents than adults. However, the effects of psychotic symptoms on outcome of depressive symptoms have not been well studied in adolescents. Depressed adolescents aged 11–17 with and without psychotic symptoms were compared on depression severity scores at baseline and at 28- or 42-week follow-up in two large UK cohorts. Psychotic symptoms were weakly associated with more severe depression at baseline in both cohorts. At follow-up, baseline psychotic symptoms were only associated with depressive symptoms in one sample; in the other, the effect size was close to zero. This supports the DSM5 system of psychotic symptoms being a separate code to severity rather than the ICD10 system which only allows the diagnosis of psychotic depression with severe depression. There was no clear support for psychotic symptoms being a baseline marker of treatment response.

Published: January 2021

Abstract
Background
There was a significant decrease in stroke admissions during the first phase of the COVID-19 pandemic. There are concerns that stroke patients have not sought medical attention and in the months after the lockdown suffer recurrent severe strokes. The aims of this study were to investigate how stroke admission rates and distributions of severity varied before, during and after the lockdown in a representative Norwegian hospital population.

Methods
All patients discharged from Akershus University Hospital with a diagnosis of transient ischemic attack (TIA) or acute stroke from January to September 2020 were identified by hospital chart review.

Results
We observed a transient decrease in weekly stroke admissions during lockdown from an average of 21.4 (SD 4.7) before to 15.0 (SD 4.2) during and 17.2 (SD 3.3) after (p < 0.011). The proportion of mild ischemic and haemorrhagic strokes was also lower during lockdown with 66% before, 57% during and 68% after (p = 0.011).

Conclusion
The period of COVID-19 lockdown was associated with a temporary reduction in total admissions of strokes. In particular, there were fewer with TIA and mild stroke. Given the need to prevent the worsening of symptoms and risk of recurrence, it is necessary to emphasise the importance to seek medical care even in states of emergency.
Use of a novel camera trapping approach to measure small mammal responses to peatland restoration

Published: January 2021

AbstractSmall mammals, such as small rodents (Rodentia: Muroidea) and shrews (Insectivora: Soricidae), present particular challenges in camera trap surveys. Their size is often insufficient to trigger infra-red sensors, whilst resultant images may be of inadequate quality for species identification. The conventional survey method for small mammals, live-trapping, can be both labour-intensive and detrimental to animal welfare. Here, we describe a method for using camera traps for monitoring small mammals. We show that by attaching the camera trap to a baited tunnel, fixing a close-focus lens over the camera trap lens, and reducing the flash intensity, pictures or videos can be obtained of sufficient quality for identifying species. We demonstrate the use of the method by comparing occurrences of small mammals in a peatland landscape containing (i) plantation forestry (planted on drained former blanket bog), (ii) ex-forestry areas undergoing bog restoration, and (iii) unmodified blanket bog habitat. Rodents were detected only in forestry and restoration areas, whilst shrews were detected across all habitat. The odds of detecting small mammals were 7.6 times higher on camera traps set in plantation forestry than in unmodified bog, and 3.7 times higher on camera traps in restoration areas than in bog. When absolute abundance estimates are not required, and camera traps are available, this technique provides a low-cost survey method that is labour-efficient and has minimal animal welfare implications.
Induction of spermatogenesis in men with hypogonadotropic hypogonadism
Authors: Morris Guy C. , Lloyd-Evans Esther , Cahill David J. 
Published: January 2021

Abstract
Purpose
We compared our clinical experience to international standards, assessed by response to treatment and pregnancy rates to ensure our results were comparable.

Methods
Men presenting with azoospermia related to hypogonadism were recruited into a treatment programme which was managed by one person over 8 years in a secondary care facility. Treatment followed published management plans using urinary gonadotropins. Data were collected on success rates in spermatogenesis, as well as variables which might predict success, and costs. Statistical analysis used non-parametric methods.

Results
Of 16 men with HH, 14 achieved spermatogenesis, and 9 had sperm cryopreserved. Of those 14, 6 were successful in achieving a pregnancy with their partner from assisted conception (including ICSI) and one after natural conception. Factors identified to identify men likely to be successful in treatment were whether testicular volume was larger at onset of gonadotropins (median 10 mL) with a trend towards greater success if the cause developed after puberty. Mean treatment costs per man treated amounted to GP£4379/UD$5377 (figures for September 2020).

Summary
Success rates from this treatment should exceed 70% in most clinical settings. The likelihood of success improves when testicular volume exceeded 10 mL at initiation of treatment and a trend exists whereby success is more likely whereby when hypogonadism developed after puberty. Treatment costs are at a level likely to benefit quality of life, supporting the delivery of this treatment and where necessary and possible, funding it in line with other fertility treatments. This treatment should be available much more widely as a management option for men with hypogonadism, allowing them to father a biological child, rather than using donor sperm.
Characterization and identification of Au pathfinder minerals from an artisanal mine site using X-ray diffraction
Authors: Nzulu Gabriel , Eklund Per , Magnuson Martin 
Published: January 2021

AbstractGold-associated pathfinder minerals have been investigated by identifying host minerals of Au for samples collected from an artisanal mining site near a potential gold mine (Kubi Gold Project) in Dunkwa-On-Offin in the central region of Ghana. We find that for each composition of Au powder (impure) and the residual black hematite/magnetite sand that remains after gold panning, there is a unique set of associated diverse indicator minerals. These indicator minerals are identified as SiO2 (quartz), Fe3O4 (magnetite) and Fe2O3 (hematite), while contributions from pyrite, arsenopyrites, iridosmine, scheelite, tetradymite, garnet, gypsum and other sulfate materials are insignificant. This constitutes a confirmative identification of Au pathfinding minerals in this particular mineralogical area. The findings suggest that X-ray diffraction could also be applied in other mineralogical sites to aid in identifying indicator minerals of Au and the location of ore bodies at reduced environmental and exploration costs.
The role of dyadic interactions between CEOs, chairs and owners in family firm governance
Authors: Sievinen Hanna Maria , Ikäheimonen Tuuli , Pihkala Timo 
Published: January 2021

AbstractThe objective of this case-based study is to understand how the dyadic interaction between the key governance actors can influence the decision-making aimed at directing and controlling a family firm. The study provides evidence that dyadic interaction at the back stage of the formal governance process can offer a privileged position for the family firm owners who serve on the board, and the non-family member Chair of the Board, to influence decision-making before, after and between board meetings. The cases studied suggest that dyadic interactions can serve as preparation for formal board processes and complement and clarify them, yet they also have the potential to conflict with them. Dyadic interaction is also shown to offer important relational and emotional benefits that may not necessarily be achieved through larger group interaction. The findings suggest that although the actors can self-regulate their behaviour through informal rules, the rules may imperfectly address one risk of dyadic interaction—the reduced cognitive conflict among the board.

Published: January 2021

AbstractDue to the fact that strontium (Sr) is not involved in the scope of supervision of drinking water in China, the Sr concentration in public drinking water and its related health risks have been neglected for a long time. In this research, public drinking water samples were collected from 314 cities across the country to reveal the concentration and spatial distribution of Sr in public drinking water. In addition, the Monte Carlo method (a statistical simulation method) was applied to evaluate the Sr intake from drinking water and human health risks among different age groups and different regions. As shown in the results, the Sr was in the concentration range of 0.005–3.11 mg/L with a mean value of 0.360 mg/L. There were significant differences in the Sr concentration in different regions; in general, it was high in the north and low in the south. The Sr intakes of infants, children, teens, and adults from drinking water were 0.273, 0.503, 0.633, and 0.784 mg/day, respectively. There was a significant positive correlation between Sr concentration in drinking water and bone mineral density (BMD) in the elderly. Especially, the correlation coefficients (r) between Sr concentration and the BMD of the elderly whose age fell in the range of 60–70 years were 0.692 (male) and 0.483 (female). In addition, the Sr concentration in drinking water was positively correlated with the incidence of children’s rickets (r = 0.411), while the Ca/Br ratio was negatively correlated with the incidence of children’s rickets (r = − 0.410). According to the health risk assessment, among people of different ages, infants’ hazard index (HI) value was the highest. The mean value and 95th percentile value were 0.066 and 0.247. Non-carcinogenic risk of Sr through drinking water among different people in different regions was less than 1, which meant no significant damage to human health. This study is the first time to systematically investigate Sr in public drinking water across the whole country. More importantly, the conclusions can be applied to risk control and management of public drinking water.
An approach to achieve overall farm feed efficiency in pig production: environmental evaluation through individual life cycle assessment
Authors: Soleimani Tara , Gilbert Helene 
Published: January 2021

Abstract
Purpose
Use a holistic individual life cycle assessment (LCA) to investigate possible mitigation of environmental impacts through optimisation of overall farm feed efficiency by combining animal selection for feed efficiency and formulation of diets with minimum environmental impacts tailored to pig nutritional requirements.

Methods
A linear multi-objective optimisation method was used to combine diet optimisation tailored to meet the representative nutritional requirements of genetic lines with environmental optimisation of the environmental impacts of the diet. Environmental optimisation was obtained by weighting the environmental impacts of the diet in a single environmental impact score. An individual trait-based LCA model with a cradle-to-farm-gate system boundary and functional unit of 1 kg live pig at the farm gate was applied to genetic lines selected for high (LRFI, high feed efficient line) and low (HRFI, low feed efficient line) feed efficiency data. The production traits of each individual animal in response to the optimised diets were simulated with InraPorc® and imported into the individual LCA model to assess global warming potential (GWP), terrestrial acidification potential (AP), freshwater eutrophication potential (EP), and land occupation (LO) of the overall farm feed efficiency approach.

Results and discussion
Integrating selection for feed efficiency, nutritional requirements of genetic lines (HRFI and LRFI) and environmental diet optimisation resulted in overall mitigation of environmental impacts. Compared to the conventional diet, the environmental score of the optimised tailored diets was reduced by 5.8% and 5.2% for LRFI and HRFI lines, respectively. At the general production system level, the environmental impacts decreased by an average of 4.2% for LRFI and 3.8% for HRFI lines compared to environmental impacts of the lines fed the conventional diet (P < 0.05). The HRFI line with its optimised tailored diet had fewer impacts than the LRFI line with the conventional diet, except for EP. Individual LCA revealed high correlations between environmental impacts and feed efficiency and protein deposition traits.

Conclusions
Implementation of overall farm feed efficiency would effectively mitigate environmental impacts. A holistic economic evaluation of the resulting trade-off between diet costs and pig performances is now needed to design a comprehensive tool to orientate selection and formulation decisions for sustainable pig production systems.

AbstractDespite successful recanalization of large-vessel occlusions in acute ischemic stroke, individual patients profit to a varying degree. Dynamic susceptibility-weighted perfusion and dynamic T1-weighted contrast-enhanced blood-brain barrier permeability imaging may help to determine secondary stroke injury and predict clinical outcome. We prospectively performed perfusion and permeability imaging in 38 patients within 24 h after successful mechanical thrombectomy of an occlusion of the middle cerebral artery M1 segment. Perfusion alterations were evaluated on cerebral blood flow maps, blood-brain barrier disruption (BBBD) visually and quantitatively on ktrans maps and hemorrhagic transformation on susceptibility-weighted images. Visual BBBD within the DWI lesion corresponded to a median ktrans elevation (IQR) of 0.77 (0.41–1.4) min−1 and was found in all 7 cases of hypoperfusion (100%), in 10 of 16 cases of hyperperfusion (63%), and in only three of 13 cases with unaffected perfusion (23%). BBBD was significantly associated with hemorrhagic transformation (p < 0.001). While BBBD alone was not a predictor of clinical outcome at 3 months (positive predictive value (PPV) = 0.8 [0.56–0.94]), hypoperfusion occurred more often in patients with unfavorable clinical outcome (PPV = 0.43 [0.10–0.82]) compared to hyperperfusion (PPV = 0.93 [0.68–1.0]) or unaffected perfusion (PPV = 1.0 [0.75–1.0]). We show that combined perfusion and permeability imaging reveals distinct infarct signatures after recanalization, indicating the severity of prior ischemic damage. It assists in predicting clinical outcome and may identify patients at risk of stroke progression.
Coronavirus biopolitics: the paradox of France’s Foucauldian heritage
Authors: Arminjon Mathieu , Marion-Veyron Régis 
Published: January 2021

AbstractIn this short paper we analyse some paradoxical aspects of France’s Foucauldian heritage: (1) while several French scholars claim the COVID-19 pandemic is a perfect example of what Foucault called biopolitics, popular reaction instead suggests a biopolitical failure on the part of the government; (2) One of these failures concerns the government’s inability to produce reliable biostatistical data, especially regarding health inequalities in relation to COVID-19. We interrogate whether Foucaldianism contributed, in the past as well today, towards a certain myopia in France regarding biostatistics and its relation to social inequalities in health. One might ask whether this very data could provide an appropriate response to the Foucauldian question: What kind of governance of life is the pandemic revealing to us?
