Managing grid impacts from increased electric vehicle adoption in African cities.

Electric vehicles are pivotal for global climate solutions, particularly in emerging markets like Africa. Despite the continent's clean energy potential, electric vehicle adoption faces unique challenges due to inefficiencies and reliability issues of distribution power grids. Here, we analyze the impacts of expanding electric vehicle fleets-private, commercial, and paratransit-on Nairobi's power grid.

Past and future of human developmental biology.

Research directly on human embryos has gone through cycles of interest and neglect. The recent revitalization, including the making of 'human developmental biology', depended on fresh supplies of material and demand for medically relevant work. Human studies relied on mice but rejected simple extrapolation from this model mammal.

'Managing values' in health economics modelling: Philosophical and practical considerations.

Stakeholder involvement has been proposed as a key strategy for appropriately managing value-laden decisions or 'value judgments' in health economics modelling. Philosophers of science, however, conceive of stakeholder involvement in research in conflicting ways, and also propose alternative strategies for 'managing values' in science. Furthermore, all proposed strategies for managing values in science raise philosophical questions and practical challenges that are difficult to resolve.

Species Choice and Model Use: Reviving Research on Human Development.

While model organisms have had many historians, this article places studies of humans, and particularly our development, in the politics of species choice. Human embryos, investigated directly rather than via animal surrogates, have gone through cycles of attention and neglect. In the past 60 years they moved from the sidelines to center stage.

Having a chat and then watching a movie: how social interaction synchronises our brains during co-watching.

How does co-presence change our neural experience of the world? Can a conversation change how we synchronise with our partner during later events? Using fNIRS hyperscanning, we measured brain activity from 27 pairs of familiar adults simultaneously over frontal, temporal and parietal regions bilaterally, as they co-watched two different episodes of a short cartoon. In-between the two episodes, each pair engaged in a face-to-face conversation on topics related to the cartoon episodes. Brain synchrony was calculated using wavelet transform coherence and computed separately for real pairs and shuffled pseudo) pairs.

Multifocal contact lens success predictability.

Purpose: The current multi-study analysis combined data from three studies to quantify the relationship between the initial reaction to soft multifocal contact lens (MFCL) design types at dispensing and evaluate the predictability of overall vision satisfaction (OVS) and intention to purchase (ITP) after 1 week of wear.

Method: Three prospective studies tested MFCLs over 1-week of wear following the same protocol, using a range of potentially predictive ratings at dispensing, and both OVS and ITP at 1-week as an indicator acceptance level. In each study, two of MyDay® multifocal, clariti® 1 day multifocal, Biofinity® multifocal (worn as a daily disposable lens) or 1 DAY ACUVUE® MOIST MULTIFOCAL were dispensed for 1-week of daily wear.

Gendering the beginning of life: Taiwanese gay fathers' navigation of preimplantation genetic diagnosis-assisted sex selection in transnational third-party reproduction.

Preimplantation genetic diagnosis (PGD) has been used not only to avoid genetic diseases and increase conception success rates but also to perform non-medical sex selection, particularly in the surging cross-border reproductive care (CBRC). In the context of commercialised biomedicine, assisted reproductive technologies, such as lifestyle sex selection, have been tailored to meet intended parents' preferences. However, there is a lack of analysis on how individuals' reproductive decisions on PGD-assisted sex selection were shaped within the sociocultural norms and CBRC.

A Novel Hybrid Technique Combining Improved Cepstrum Pre-Whitening and High-Pass Filtering for Effective Bearing Fault Diagnosis Using Vibration Data.

Rolling element bearings (REBs) are an essential part of rotating machinery. A localised defect in a REB typically results in periodic impulses in vibration signals at bearing characteristic frequencies (BCFs), and these are widely used for bearing fault detection and diagnosis. One of the most powerful methods for BCF detection in noisy signals is envelope analysis.

Combining isotope ratios for provenancing Viking Age iron artefacts in the British Isles: a pilot study.

Stable and radiogenic isotope analysis - particularly using lead isotope analysis (LIA) - has previously been shown to be a useful tool for the provenancing of ancient metal artefacts of silver and copper and its alloys, but less progress has been made in the provenancing of iron artefacts, despite their importance and frequency in the archaeological record. In this pilot study we investigate for the first time the possibilities of iron isotope analysis in combination with trace strontium isotope analysis and LIA for the provenancing of iron objects believed to be from the Viking Age in the British Isles. Previous studies have shown that analysis of each of these isotopes can contribute to provenancing iron artefacts, but they are not individually resolutory.

Using intersectionality to study gender and antimicrobial resistance in low- and middle-income countries.

Different sexes and genders experience differentiated risks of acquiring infections, including drug-resistant infections, and of becoming ill. Different genders also have different health-seeking behaviours that shape their likelihood of having access to and appropriately using and administering antimicrobials. Consequently, they are distinctly affected by antimicrobial resistance (AMR).

No brute facts: The Principle of Sufficient Reason in ordinary thought.

The Principle of Sufficient Reason (PSR) has been an influential thesis since the earliest stages of western philosophy. According to a simple version of the PSR, for every fact, there must be an explanation of that fact. In the present research, we investigate whether people presuppose a PSR-like principle in ordinary judgment.

Patient and Public Involvement in Health Economics Modelling Raises the Need for Normative Guidance.

Patient and public involvement in health economics research and health technology assessment has been increasing for some time; however, patient and public involvement in health economics modelling is a more recent development. One reason to advance this type of involvement is to help appropriately manage the social and ethical value judgements that are required throughout model development and interpretation. At the same time, patient and public involvement in health economics modelling raises numerous practical and philosophical issues that invite discussion and debate.

Rational learners and parochial norms.

Parochial norms are narrow in social scope, meaning they apply to certain groups but not to others. Accounts of norm acquisition typically invoke tribal biases: from an early age, people assume a group's behavioral regularities are prescribed and bounded by mere group membership. However, another possibility is rational learning: given the available evidence, people infer the social scope of norms in statistically appropriate ways.

Familiarity with, perceptions of and attitudes toward butterflies of urban park users in megacities across East and Southeast Asia.

Perceptions of, and attitudes toward, wildlife are influenced by exposure to, and direct experiences with, nature. Butterflies are a conspicuous and ubiquitous component of urban nature across megacities that are highly urbanized with little opportunity for human-nature interactions. We evaluated public familiarity with, perceptions of and attitudes toward butterflies across nine megacities in East and Southeast Asia through face-to-face interviews with 1774 urban park users.

Patronage, partnership, voluntarism: Community-based health insurance and the improvisation of universal health coverage in Senegal.

The turn towards Universal Health Coverage (UHC) in the past decade raises the question of the role of the state, following years of state withdrawal and a fragmented approach to public health. Senegal introduced its version of UHC, Couverture Maladie Universelle (CMU) in 2013 and this paper explores early efforts to fund it through the establishment of community-based health insurance (CBHI). The paper draws on ethnographic research at mutual health organisations, or mutuelles de santé as they are commonly referred to in francophone countries, which manage CBHI.

Pluralizing measurement: Physical geodesy's measurement problem and its resolution.

Derived measurements involve problems of coordination. Conducting them often requires detailed theoretical assumptions about their target, while such assumptions can lack sources of evidence that are independent from these very measurements. In this paper, I defend two claims about problems of coordination.

An exploration of parental age in relation to parents' psychological health, child adjustment and experiences of being an older parent in families formed through egg donation.

Research Question: Is parental age associated with parents' psychological health, couple relationship satisfaction and child adjustment in egg donation families, and how do parents think and feel about their age in relation to parenting?

Design: Seventy-two families with a child born after IVF egg donation were included. Mothers were aged between 32 and 51 years and fathers between 31 and 61 years when the target child was born. When the child was aged 5 years, parents were interviewed and asked to complete questionnaire assessments of parenting stress, anxiety, depression, marital quality and child adjustment.

Perceived stress during the prenatal period: assessing measurement invariance of the Perceived Stress Scale (PSS-10) across cultures and birth parity.

Maternal prenatal stress places a substantial burden on mother's mental health. Expectant mothers in low- and middle-income countries (LMICs) have thus far received less attention than mothers in high-income settings. This is particularly problematic, as a range of triggers, such as exposure to traumatic events (e.

Did Einstein predict Bose-Einstein condensation?

The successful prediction of new phenomena by scientific theories has gained much interest in philosophy. I will discuss a case that is often taken to be such a successful prediction within physics: Bose-Einstein condensation. The common story goes: the phenomenon was predicted in 1925 by Einstein, and the prediction was confirmed in 1995 ​at JILA and MIT.

The particularity of freedom and recovery from addiction in practice: On the therapeutic limitations of generalising addiction science.

Addiction science is very often cast as an indispensable source of political justification and clinical resources for engaging addicts therapeutically rather than punitively. It is said to promote an image of overcoming addictions as projects of recovery from disease or mental disorder rather than merely a repudiation of one's formerly troubled ways. Thusly, it is said to inform more compassionate and effective approaches to fostering constructive personal change than merely blaming and punishing addicts for their difficulties.

The Brazilian Green Revolution.

This article analyzes the critical geopolitics of knowledge production in Brazil during the 20 century. It offers a critical appraisal of recent calls to decolonize political geography by locating the role played by actors and institutions in the Global South within the broader narrative of the Green Revolution. Historical accounts of the Green Revolution have only recently started to incorporate perspectives of and attribute agency to actors in the Global South.
