Ice nucleation activity of bacteria isolated from snow compared with organic and inorganic substrates

Environmental context. Biological ice nucleators have been found to freeze water at very warm temperatures. The potential of bio-aerosols to greatly influence cloud chemistry and microphysics is becoming increasingly apparent, yet detailed knowledge of their actual role in atmospheric processes is lacking. The formation of ice in the atmosphere has significant local, regional and global influence, ranging from precipitation to cloud nucleation and thus climate. Ice nucleation tests on bacteria isolated from snow and laboratory-grown bacteria, in comparison with those of known organic and inorganic aerosols, shed light on this issue. Abstract. Ice nucleation experiments on bacteria isolated from snow as well as grown in the laboratory, in comparison with those of known organic and inorganic aerosols, examined the importance of bio-aerosols on cloud processes. Snow samples were collected from urban and suburban sites in the greater Montreal region in Canada (45°28′N, 73°45′W). Among many snow bacterial isolates, eight types of bacterial species, none belonging to known effective ice nucleators such as Pseudomonas or Erwinia genera, were identified to show an intermediate range of ice nucleation activity (–12.9 ± 1.3°C to –17.5 ± 2.8°C). Comparable results were also obtained for molten snow samples and inorganic suspensions (kaolin and montmorillonite) of buffered water solutions. The presence of organic molecules (oxalic, malonic and succinic acids) had minimal effect (<2°C) on ice nucleation. Considering experimental limitations, and drawing from observation in snow samples of a variety of bacterial populations with variable ice-nucleation ability, a shift in airborne-species population may significantly alter glaciation processes in clouds.
Correlation of plasma fibrinogen and mean platelet volume in patients of sepsis to the severity of sepsis and its outcome

Background: The prognostic value of mean platelet volume (MPV) and plasma fibrinogen level in terms of survival in patients with sepsis and septic shock is still incompletely documented. The aim of the present study was to find a correlation between MPV and plasma fibrinogen with the severity of sepsis and mortality. Methods: Three hundred eleven patients having quick sequential organ failure assessment score 2/3, systolic blood pressure ≤100 mmHg, respiratory rate ≥22/minute and altered mentation <15 (Glasgow coma scale) were included for this prospective observational study. Acute physiology and chronic health evaluation (APACHE) II score, MPV on days one and four, fibrinogen on days one and seven were tested. The number of days of intensive care unit (ICU), and hospital stay, in-hospital mortality was recorded. Categorical and continuous variables were tested using the chi-square test/Fisher’s exact test and analysis of variance/Kruskal-Wallis H test respectively. Results: The mean plasma fibrinogen at day one and day seven was significantly higher in patients who had septic shock and in expired patients. The mean MPV at day four was significantly higher in patients who expired compared to those who survived. The mean MPV on day four was significantly higher compared to the mean MPV at day one in patients who expired. Conclusions: Fibrinogen level at admission is the predictor of mortality in patients with sepsis or septic shock. An increase in MPV was strongly correlated with mortality and can be used as a prognostic indicator.
How does a single community grant multiple social licences for a problematic metro project? Reflections from a dynamic perspective

ABSTRACT Gaining a social licence to operate (SLO) is important to ensure a smooth-going metro project, yet few relevant studies exist. Using a small but eventful case from Nanjing, China, this study considers how a metro station construction project is assigned overlapping and fluid social licences by a local community and how these social licences interact with the project. The analytical framework is underpinned by two ‘continuum’ theories, one developed by Thomson and Boutilier and one by Dare et al. , and incorporates the perspective of the project life cycle and movements of social resistance. The results reveal that a uniform, community-level SLO diverged into multiple SLOs with different characteristics. However, the changes in the SLO were decoupled from the life cycle of the metro project, as work was not only halted due to opposition but also resumed amidst such opposition. The governmental interventions, manipulative resistance and unqualified impact assessments were the main driving forces in the dynamic procedure. Based on the results and analysis, we highlight several policy implications.
Photo Elicitation and the Sociology of Taste: A Review of the Field, Empirical Illustrations, Arguments for A “Return to Photography”

ABSTRACT The recent flourishing of visual methods is not mirrored in studies of taste. This paper engages with photo elicitation (PE), which Bourdieu applied in Distinction, but never elaborated on. We conducted systematic photo-interviewing in arts, fiction and architecture. After reviewing the relevant literature, we highlight illustrative findings and discuss the potential of PE. In studies of taste, PE helps in bridging “social worlds”, and can unveil class-based repertoires for understanding culture. It provides entry to tacit knowledge, and aids comparisons. Importantly, when two methods, PE and oral interviewing, are used in combination, this significantly helps substantiate our findings.
Theoretical Evaluation of the Melting Efficiency for the Single-Screw Micro-Extrusion Process: The Case of 3D Printing of ABS

One of the challenges for single-screw micro-extrusion or additive manufacturing (AM), thus 3D printing, of polymers is controlling the melting efficiency so that energy and equipment costs can be minimized. Here, a numerical model is presented for AM process design, selecting acrylonitrile–butadiene–styrene (ABS) as viscoelastic reference polymer. It is demonstrated that AM melting is different compared to conventional melting due to variation in extrusion dimensions, leading to a different balance in heating by conduction and viscous heat dissipation as caused by the shearing between the melt layers in the associated film layer near the barrel. The thickness of this melt film layer is variable along the screw length, and it is shown that simplified models assuming an overall average value are too approximate. It is highlighted that the screw frequency, pitch angle and compression ratio are important process parameters to control the point of melt finalization. In addition, the power-law index reflecting the shear thinning nature of the polymer melt is showcased as a key parameter. Moreover, AM process results assuming constant and temperature dependent specific heat capacities and thermal conductivities are compared. The current work opens the door for on-line AM process control, addressing all relevant operating and material parameters.
Predicting college students’ intention to purchase local food using the theory of consumption values

ABSTRACT While extensive research has been conducted on local food and consumer behavior, there is little research investigating college students’ intention regarding purchasing local food. The purpose of this study is to examine the factors that motivate college students to purchase local food. The theory of consumption values, which uses five primary values to explain buying behavior, is applied in this study. In addition, this study also identified a significant moderator, place attachment, on the relationship between consumption values and consumers’ behavioral outcomes. The survey was distributed to college students enrolled in a university in the southeastern United States. The results present that emotional, functional, and epistemic values are significantly related to the intention to consume local food whereas social and conditional values are not. Moreover, place attachment significantly moderated the relationship between social value and intention to consume local food. Significant theoretical and managerial implications are discussed.
nuSTORM at CERN: Feasibility Study

The nuSTORM collaboration is presented in the addendum. Abstract nuSTORM (“Neutrinos from Stored Muons”) is a short-baseline neutrino project based on a low-energy muon decay ring. The scientiﬁc objectives of nuSTORM are: to make detailed and precise measurements of neutrino-nucleus interactions not only as a service to the long- and short-baseline neutrino oscillation programmes but also as a means of studying the nucleus using a weak probe and seeking evidence for non-standard interactions; and to take forward the search for light sterile neutrinos should the results of the Short Baseline Neutrino (SBN) programme at FNAL indicate that such a programme is required. The feasibility of implementing nuSTORM at CERN has been studied by the nuSTORM group as part of the CERN Physics Beyond Colliders study. An outline of the proposed siting of nuSTORM at CERN is presented. The SPS would provide the primary beam and offers a credible location for fast extraction towards a suitable green ﬁeld site
Cognitive Neuroscience of Visual Working Memory

This chapter takes the perspective that ‘working memory’ refers to a class of behaviours that can be accomplished by the coordinated recruitment of sensory-, representational-, action-, and control-related mechanisms and representations. There is no working memory system, per se. This idea is illustrated with findings from cognitive neuroscience, with an emphasis on studies of human working memory with functional magnetic resonance imaging and electroencephalography, and on simulations of human behaviour with recurrent neural network modelling. Understanding principles of attention and oculomotor control are central to understanding the selection of stimulus information and its retention ‘in’ working memory, as well as for the moment-to-moment prioritization of subsets of the contents of working memory. Recent research from a dynamical systems perspective suggests a principled framework for understanding how, and under what circumstances, knowledge from long-term memory is recruited to support working memory performance. An important challenge for contemporary cognitive neuroscience is to develop an accepted procedure for assessing when multiple regions can be shown to represent stimulus-specific information, whether these regions are all supporting the same function, or perhaps different functions that nonetheless all entail the active representation of the same information.
Trauma-Informed Self-Care for Child and Youth Care Workers

This article presents a framework for understanding, developing, and applying a trauma-informed approach to staff, team, and organizational self-care in youth serving organizations. The article draws on current research in the areas of Adverse Childhood Experiences (ACE), Trauma-Informed Care (TIC), Trauma Stewardship, resilience, and The Sanctuary Model. This approach will help child and youth care workers to develop a long lasting, effective trauma-informed self, team, and organizational care plan. The first article focuses on worker traumainformed self-care, and the second on team and organizational approaches. Since there are limits as to what can be comprehensively covered in a short article, I will supply an extensive list of key references and resources relevant to self, team, and organizational care. Many of these are directly downloadable from the Internet. Thus, I do not attempt to answer all the issues but encourage readers to explore the various resources and ideas and apply them where relevant to the readers, their team, and organizations.
Immigration Attitudes and White Americans’ Responsiveness to Rising Income Inequality

Despite decades of rising inequality, there has been little observed increase in American public support for redistribution. This is puzzling because majorities of Americans profess to be aware of and opposed to high inequality. I argue that this lack of responsiveness is not due to public ignorance of, nor apathy toward, inequality but rather, in part, to negative feelings toward immigrants, a growing, politically salient, and negatively stereotyped “out-group” that is widely viewed as a target of redistributive spending. To test this, I combine data on state-level income inequality with survey data from the 1992 to 2016 Cumulative ANES. I find that growing inequality can prompt support for redistribution but that this depends, in part, on peoples’ immigration attitudes. Overall, these results suggest that immigration has important implications for economic redistribution in an era of high, and rising inequality.
Prevalence of JAK2 V617F Mutation in Iranian Patients with Myeloproliferative Neoplasms

Background and Aim: Multiple lines of evidence have been suggested that JAK2 is likely the main candidate gene responsible for the pathogenesis of myeloproliferative neoplasms. The V617F mutation in the pseudokinase domain of JAK2 protein has been detected in a majority of patients. We aimed to evaluate the frequency of this somatic missense substitution among Iranian patients with myeloproliferative neoplasms. Methods Peripheral blood samples were collected from patients with myeloproliferative neoplasms across different regions of Iran. The JAK2 V617F mutation was identiﬁed by allele-speciﬁc PCR. To confirm the PCR results, randomly selected positive and negative samples were sequenced. Results: Among 72 identified patients, 45 (62.5%) were found to harbor JAK2 V617F. The frequencies of the mutation ranged 100% for primary myelofibrosis, 75% for chronic myelogenous leukemia, 67% for polycythemia vera, 62.5% for myelodysplastic/myeloproliferative neoplasms, and 52% for essential thrombocythemia. Our findings revealed that the mutation was more common among men in comparison with women and the correlation between the mutation and gender was statistically significant (p-value<0.01). Additionally, the presence of JAK2 V617F was associated with older ages (p-value =0.009). Conclusion: The JAK2 V617F mutation was detected in 62.5% of patients with myeloproliferative neoplasms. We have shown that this single acquired point mutation was presented in at least half of the patients. Hence, it seems that the identification of JAK2 V617F mutation in myeloproliferative neoplasms can be very effective in disease diagnosing and management. *Corresponding Author: Mohammad Hamid; Email: hamidi@pasteur.ac. ir Please cite this article as: Hamid M, Shahbaz Z.

Stress and family relationships among college student parents: A mixed methods study

College student parents represent a unique population because they are typically low-income, accrue more debt than traditional students, and must balance the role of student and parent. Using a mixed methods design, this study examined the relation between college student parents’ stress and distress in their relationships with their children and examined how parents managed their multiple roles. Parent participants (n = 80; 54 mothers, 26 fathers; M age = 28.74 years, SD = 4.72) completed an online survey and a subsample (n = 14) participated in semi-structured interviews. Results revealed that college student parents experience a variety of stressors that spillover into their relationships with their children and these associations appear more detrimental for father-child relationships. However, in-depth qualitative interviews not only highlighted the various sources of stress (e.g., time demands, multiple roles), but also revealed internal and external resources that college student parents draw on to help cope with stressors. Findings suggest that program efforts to strengthen the co-parenting relationship and to help college student parents more effectively manage their stress may be beneficial for improved parent-child relationships.
Persistence and fate of 2,3,4,6‐tetrachlorophenol and pentachlorophenol in limnocorrals

Three separate limnocorral experiments were conducted to assess the fate and effects of a commercial 2,3,4,6‐tetrachlorophenol (TeCP) formulation (DIATOX®; 19.4% TeCP, 4.8% pentachlorophenol [PCP], 75.8% “inert” buffers) in an aquatic ecosystem. Nominal treatment concentrations for experiments 1 and 2 were 0.075 and 0.75 mg active ingredient (a.i.)/L and 0.75 and 1.50 mg a.i./L DIATOX®, respectively, with three replicates of each treatment. Pesticide was applied in the morning for experiment 1 and in the evening for experiment 2. For Experiment 3, unreplicated concentrations of 0.1, 0.25, 0.5, 1.0, 2.0, 4.0, and 7.3 mg a.i./L DIATOX® were chosen; pesticide was applied in the evening. In all three experiments, the pesticide was applied as a single, uniform surface treatment. Both TeCP and PCP dissipated rapidly from the water of treated limnocorrals. Times to 50% dissipation for TeCP and PCP in the integrated water column were generally similar within experiments but ranged from 0.4 to 1.1 d following the morning application of experiment 1 to 3.4 to 7.3 d following the evening applications of experiments 2 and 3. The faster initial dissipation of TeCP and PCP from the water following the morning application implicated photolysis as the primary degradation mechanism, as did the faster dissipation of chlorophenols from the surface layer than from other water depths during experiment 2. Aqueous dissipation rates for both compounds from the integrated water column were similar in all three experiments after the initial mixing period (1–4 d); the three‐experiment average first‐order rate coefficient for either compound after day 4 was 0.09/d. From a mass balance perspective, the majority of the chlorophenols remained in the water column. Neither compound accumulated in the sediments to any significant extent (< 0.1% of applied mass), but sediment‐associated residues did dissipate at a considerably slower rate than residues in the water column. From 97 to >99% of the applied chlorophenols had dissipated from the water of treated enclosures by the end of the various experiments (42–63 d).
Degree of Counterion Binding of Alkylpyridinium Halide Micelles: Its Relation to Micelle Shape and Size

From electromotive force measurements with surfactant and halide ion-selective electrodes, we obtained the degree of counterion binding (β) of dodecylpyridinium bromide (DPB) and iodide (DPI) and tetradecylpyridinium bromide (TPB) micelles in aqueous sodium halide solutions with concentrations of 0 - 20 mM. Under a geometrical consideration the micelle shapes and the surface densities of head group (s-1) of these micelles were deduced from aggregation numbers evaluated from their relationships to the added salt concentration previously reported. The spherical micelles of TPB having the shape of an oblate ellipsoid had a constant β, 0.76, independently of s-1. In the case of the spherical micelles of DPB, β was found to be 0.79 for sphere-shaped micelles and 0.82 for ellipsoidal ones. For DPI we obtained β values of 0.84 and 0.99 for the spherical micelles with the shape of an oblate ellipsoid and the rodlike micelles, respectively. From these dependences of β on micelle shape and s-1, we conclude that β of micelles investigated increases in the order of sphere-shaped < oblately ellipsoidal < rodlike micelles but is independent of the micelle size unless the micelle shape changes.
Music and mindfulness meditation: Comparing four music stimuli composed under similar principles

Mindfulness meditation has frequently used sound and music as an important component. However, research on effective music stimuli is scarce. After a series of studies evaluating the most effective, useful, and preferred auditory stimuli, we were interested in exploring whether these effective musical features were transferred to new music. In this study, we evaluate our original music stimuli with three new stimuli composed under similar principles. Non-musician and musician participants (N = 114) in a multisite study evaluated their mindfulness state after listening to four music stimuli, and rated their usefulness and preference. Results from a repeated-measures analysis of variance (ANOVA) at each site indicated no significant difference in mindfulness effectiveness. Friedman’s ANOVAs for the usefulness of the music stimuli showed similar non-significant results in both sites. A mixed model among sites did not show significant differences among groups. Preference rankings were not significantly different for non-musicians, but musicians did show a statistically significant preference of the Original stimuli over Stimulus 2, probably due to sound quality. These results indicate the feasibility of transferring previously researched and effective musical features to new stimuli. Identifying the effective “active ingredients” of music interventions may be one way of supporting evidence-based practice in music therapy.
A standardized database of Marine Isotopic Stage 5e sea-level
proxies on tropical Pacific Islands

Marine Isotope Stage 5 deposits have been reported on many tropical Pacific islands. This paper presents a database compiled through the review of MIS 5e (last interglacial – LIG) coral reef records from islands belonging to French Polynesia (Anaa, Niau, Makatea, Moruroa, Takapoto, Bora Bora), the Hawaiian Islands (Oahu, Lanai, Midway Atoll), Tuvalu, Kiribati (Christmas Island, Tarawa), the Cook Islands (Mangaia, Atiu, Mitiaro, Mauke, Pukapuka, Rakahanga, Rarotonga), Tonga, Samoa, the Federal States of Micronesia, the Mariana Islands, the Marshall Islands (Enewetak, Bikini), New Caledonia, Papua New Guinea, the Solomon Islands, Vanuatu, Fiji and Niue. Studies reporting other sea-level indicators dated to other Pleistocene interglacials and Holocene sea-level indicators were not inserted in the database but are included in this data description paper for completeness. Overall, about 300 studies concerning Pleistocene and Holocene sea-level indicators have been reviewed, and finally 163 age data points and 94 relative sea-level (RSL) data points from 38 studies on the MIS 5e have been inserted in the database. An additional 155 age data points have been reviewed; i.e. the tropical Pacific islands database contains 318 age data points. The main sea-level indicators include emerged coral reef terraces, but also reef units recovered in drill cores from a few islands, thus reflecting the diversity of tectonic settings and sampling approaches. Future research should be directed towards better constrained RSL reconstructions, including more precise chronological data, more accurate elevation measurements and a better refinement of the palaeo-water-depth significance of coralgal assemblages. The database for tropical Pacific islands is available open access at this link: https://doi.org/10.5281/zenodo.3991672 (Hallmann and Camoin, 2020).
