We analyzed data from the Wisconsin Longitudinal Study (N = 6390) to investigate how common an emerging adulthood-type lifestyle (e.g., delayed marriage and childbearing, pursuit of higher education) was in the late 1950s and early 1960s, and what the long-term psychological-health correlates were of such a lifestyle. Cluster analyses of marital, childbearing, educational, and occupational variables from 1957 (high school graduation) to 1964 generated six clusters that we labeled: fast-starters (early marriage and childbearing, little education beyond high school, virtually all employed), very-educated/partnered (mean educational attainment well into graduate school and among the earliest to get married), moderately educated/family oriented (mean years of education somewhat shy of a bachelor's degree, early marriage and childbearing), educated singles (late marriage and childbearing, if at all, averaging a bachelor's degree; most prototypical of emerging adulthood), work/military first (little education past high school, late marriage and childbearing), and military/professional aspiration (envisioning career requiring college education and pursuing one)...

Mechanical objects have important practical applications in the fields of quantum information and metrology as quantum memories or transducers for measuring and connecting different types of quantum systems. The field of electromechanics is in pursuit of a robust and highly coherent device that couples motion to nonlinear quantum objects such as superconducting qubits. Here, we experimentally demonstrate a high-frequency bulk acoustic wave resonator that is strongly coupled to a superconducting qubit using piezoelectric transduction with a cooperativity of 260...

Alysson E Light, Kimberly Rios, Kenneth G DeMarree
The current research examines factors that facilitate or undermine goal pursuit. Past research indicates that attempts to reduce self-uncertainty can result in increased goal motivation. We explore a critical boundary condition of this effect-the presence of alternative goals. Though self-regulatory processes usually keep interest in alternative goals in check, uncertainty reduction may undermine these self-regulatory efforts by (a) reducing conflict monitoring and (b) increasing valuation of alternative goals...

Martin Kitchener, Aoife M McDermott, Simon Cooper
Purpose While critical approaches have enriched research in proximate fields, their impact has been less marked in studies of healthcare management. In response, the 2016 Organizational Behaviour in Health Care Conference hosted its first-ever session dedicated to the emergent field of critical healthcare management studies (CHMSs). The purpose of this paper is to present five papers selected from that conference. Design/methodology/approach In this introductory paper, the authors frame the contributions as "green shoots" in a field of CHMS which contains four main furrows of activity: questioning the taken-for-granted; moving beyond instrumentalism; reflexivity and meanings in research; and challenging structures of domination (Kitchener and Thomas, 2016)...

Heshouwu, derived from the root of Polygonum multiflorum (=Fallopia multiflora), is widely used in the Chinese medicine market as a traditional tonic. The emergence of heshouwu material with a human shape reflects a pursuit of its supplementing effects. However, reports of Heshouwu toxicity have repeatedly surfaced in recent years, attracting widespread concern. To clarify the situation surrounding the safety and efficacy of Heshouwu, this research utilizes a systematic review of the text and illustrations in historical bencao (materia medica) literature to investigate the origin, botanical characteristics, actions and processing of Heshouwu, as well as the origin and historical evolution of Baishouwu ("white Heshouwu")...

REVIEW
Ainhoa Nieto Gutierrez, Patricia H McDonald
G protein-coupled receptors (GPCRs) constitute the largest and most diverse protein family in the human genome with over 800 members identified to date. They play critical roles in numerous cellular and physiological processes, including cell proliferation, differentiation, neurotransmission, development and apoptosis. Consequently, aberrant receptor activity has been demonstrated in numerous disorders/diseases, and as a result GPCRs have become the most successful drug target class in pharmaceuticals treating a wide variety of indications such as pain, inflammation, neurobiological and metabolic disorders...

Insights from preclinical and clinical studies have attempted to highlight the importance of modified lipoprotein particles in the pathogenesis of cardiovascular diseases (CVD). However, evidence is not conclusive. Since there is a relative dearth of clinical research in collecting useful information from traditional advanced lipoproteins testing, this present editorial introduces the aim of a special issue on modified lipoproteins as potential biomarkers for CVD. This issue aims at gathering a selection of insightful articles that address major challenges related to potential clinical use of modified lipoproteins as new CVD biomarkers...

Developing a facile and reliable method for the fabrication of transition metal chalcogenides is a vital and endless pursuit of scientific and technological disciplines. In this work, we develop a one-pot solution approach to obtain copper selenide nanostructures with different morphologies and crystal structures (Cu2Se nanoparticles, CuSe nanoplates and CuSe2 nanosheets). In comparison to previously reported methods, our method did not use expensive and very toxic raw materials. After detailed studies of reaction conditions, including temperature, reaction time, and feeding amount of surfactants and precursors, we found that the feeding ratio of precursors played a key role in the crystal structures and morphologies of the final products...

AIMS: Poverty kills children. This study assesses the relationship between poverty and child mortality rates (CMRs) in 71 societies from three world regions to determine whether some countries, relative to their region, neglect their children. METHODS: Spearman rank order correlations were calculated to determine any association between the CMR and poverty data, including income inequality and gross national income. A current CMR one standard deviation (SD) above or below the regional average and a percentage change between 1988 and 2010 were used as the measures to assess the progress of nations...

Recently, there has been an increasing focus on the pursuit of targets considered to be less-druggable that offer potential for development of promising new therapeutic agents for the treatment of diseases with large unmet medical need, particularly in the areas of oncology and virology. However, conducting drug discovery campaigns in "beyond Rule of 5" (bRo5) chemical space presents a significant drug design and development challenge to medicinal chemists to achieve acceptable oral pharmacokinetics. Retrospective analysis of past successes and failures in drug discovery bRo5 may shed light on the key principles that contribute to the oral bioavailability of successful bRo5 compounds and improve the efficiency of drug design for future projects...

This article explores upper secondary school students' understandings and experiences of health in Denmark, where public health promotions appeal to pleasure. Health promotion thereby taps into capitalist society's 'imperative of enjoyment', which reproduces ideological fantasies about the fulfilment of desires through the consumption of health. Based on qualitative empirical material produced through participatory and visual methods during fieldwork conducted in 2012, the analysis shows that relations between healthiness and pleasure are conflated and paradoxical: the students try to fit into society not only by being healthy, but also by enjoying healthiness; but if they fail pleasure, they fail healthiness and experience a loss of individual social value...

The salmon louse (Lepeophtheirus salmonis [Krøyer]) is an ectoparasitic copepod that causes disease in farmed Atlantic salmon (Salmo salar) and may play a role in the decline of some wild salmonid populations. Controlling lice infestations is a major cost for the salmon industry; this has stimulated the pursuit of alternative approaches to controlling them. One such approach involves determining, and then disrupting, the sensory cues used by the parasite to find its host. In this context, we examined the behavioural responses of lice copepodids to light flicker-simulating light reflecting from the sides of the salmon host and/or the shadows cast by fish passing overhead-and water-soluble chemicals released from the skin of the salmon...

Scientific research at universities has a crucial role in leveraging a country's innovative potential. Sectors that require greater investments in technology for the development of their research, such as biotechnology, need to be aware of the frontier state-of-the-art technology and the knowledge incrusted within it. Although the information available in scientific articles is well explored in academic environment, the patent literature, where much of the technological information is present, is still poorly accessed...

The history of resistance training research began with anecdotal ideas and a slow growth of research from the late 1890s through the 1970s. The mid-1970s were a nexus point when resistance training studies evolved from just strength assessments to importance in physiological systems, physical health, and physical performance capabilities for individuals interested in physical fitness through to those seeking elite athletic performances. The pursuit of understanding program design and what mediated successful programs continues today as new findings, replication of old concepts, and new visions with the latest technologies fuel both our understanding and interest in this modality...

Perfluorinated carboxylic acids (PFCAs) of different carbon chain lengths are chemicals of concern to human health and their removal, using conventional remediation technologies, is challenging. The present paper pursuits thermal and photo-induced degradation of PFCAs (F(CF2)nCOOH, n = 1-9) under various concentrations of four different acids (HNO3, H2SO4, HCl, and H3PO4) covering a range of strong acidic to basic pH. For thermal-induced experiments, the temperature was set at 40 °C, 60 °C, and 80 °C at acid strengths of 0...

Cloud cover is inevitable in optical remote sensing (RS) imagery on account of the influence of observation conditions, which limits the availability of RS data. Therefore, it is of great significance to be able to reconstruct the cloud-contaminated ground information. This paper presents a sparse dictionary learning-based image inpainting method for adaptively recovering the missing information corrupted by thick clouds patch-by-patch. A feature dictionary was learned from exemplars in the cloud-free regions, which was later utilized to infer the missing patches via sparse representation...

OBJECTIVE: Physical activity is important for maintaining health throughout the lifespan. However, adherence to PA regimens is poor with approximately 50% of older adults terminating activity intervention programs within 6 months. In this study we tested whether gray matter volume and white matter microstructural integrity prior to the initiation of a PA intervention predicts PA adherence. METHODS: 159 adults aged 60-80 years were randomly assigned to a moderate-intensity aerobic walking condition or a non-aerobic stretching and toning condition...
