Droplet deformation by short laser-induced pressure pulses
Authors: Reijers Sten A. , Snoeijer Jacco H. , Gelderblom Hanneke 
Published: September 2017

When a free-falling liquid droplet is hit by a laser it experiences a strong ablation-driven pressure pulse. Here we study the resulting droplet deformation in the regime where the ablation pressure duration is short, i.e. comparable to the time scale on which pressure waves travel through the droplet. To this end, an acoustic analytic model for the pressure, pressure impulse and velocity fields inside the droplet is developed in the limit of small density fluctuations. This model is used to examine how the droplet deformation depends on the pressure pulse duration while the total momentum to the droplet is kept constant. Within the limits of this analytic model, we demonstrate that when the total momentum transferred to the droplet is small the droplet shape evolution is indistinguishable from an incompressible droplet deformation. However, when the momentum transfer is increased the droplet response is strongly affected by the pulse duration. In this later regime, compressed flow regimes alter the droplet shape evolution considerably.
Centennial to millennial hydroclimatic fluctuations in the humid northeast United States during the Holocene
Authors: Shuman Bryan N. , Burrell Sara A. 
Published: September 2017

AbstractPaleoclimate records indicate that the hydroclimate of the northeast United States changed continuously during the Holocene, but the signals of multi-century variations have been difficult to distinguish from local effects and noise. Systematic replication of the signals can help diagnose the patterns of change. Here, we use ground-penetrating radar (GPR) and sediment core analyses to extend and compare the regional network of lake-level records. We reconstruct the histories of two lakes in northeast Pennsylvania, which show that multi-century hydrologic changes observed in coastal New England extended to the Susquehanna River watershed. Correlations with isotopic and marine temperature records (r>0.65) indicate that high temperatures coincided with low water at 4.9–3.8 and 2.8–2.0 ka. Widely recognized Holocene events at ca. 4.2 and 2.7 ka, therefore, may have shared similar ocean-atmosphere dynamics in this region. Low water levels in Pennsylvania from ca. 5.5–4.9 ka, however, demonstrate that other multi-century changes had different patterns. At ca. 5.5 ka, anti-phased inland and coastal hydrologic changes followed a sharp temperature decline and produced drought possibly as far inland as the Great Lakes. The long-term increase in water levels since then underscores that current pluvial conditions in the region probably lack a Holocene precedent.
ON THE ORDER STRUCTURE OF REPRESENTABLE FUNCTIONALS
Authors: TARCSAY ZSIGMOND , TITKOS TAMÁS 
Published: September 2017

AbstractThe main purpose of this paper is to investigate some natural problems regarding the order structure of representable functionals on *-algebras. We describe the extreme points of order intervals, and give a non-trivial sufficient condition to decide whether or not the infimum of two representable functionals exists. To this aim, we offer a suitable approach to the Lebesgue decomposition theory, which is in complete analogy with the one developed by Ando in the context of positive operators. This tight analogy allows to invoke Ando's results to characterize uniqueness of the decomposition, and solve the infimum problem over certain operator algebras.
How can research partnerships better support local development? Stakeholder perceptions on an approach to understanding research partnership outcomes in the Canadian Arctic
Authors: Brunet Nicolas D. , Hickey Gordon M. , Humphries Murray M. 
Published: September 2017

ABSTRACTUnderstanding the benefits and outcomes of Canada's public investment in Arctic science and associated community–researcher partnerships represents a significant challenge for government. This paper presents a capital assets-based approach to conceptualising northern research partnership development processes and assessing the potential outcomes. By more explicitly considering the pre- and post-partnership asset levels (that is, social, human, physical, financial and natural assets) for different collaborators, the potential benefits and challenges associated with community–researcher partnerships can be collaboratively assessed. In order to help refine this approach, we conducted a survey of those involved in developing and maintaining community–researcher partnerships across Arctic Canada. Results indicate that the proposed approach could be useful for research funding agencies seeking to better understand partnership outcomes and promote more effective community–researcher interactions. Challenges include adequately capturing the qualitative nature of different capital assets, pointing to future research and policy needs. Better understanding the role of research in northern development has the potential to improve northern research, policy and practice.
Effects of cognitive remediation on negative symptoms dimensions: exploring the role of working memory

Published: September 2017

BackgroundRecent theories suggest that poor working memory (WM) may be the cognitive underpinning of negative symptoms in people with schizophrenia. In this study, we first explore the effect of cognitive remediation (CR) on two clusters of negative symptoms (i.e. expressive and social amotivation), and then assess the relevance of WM gains as a possible mediator of symptom improvement.MethodData were accessed for 309 people with schizophrenia from the NIMH Database of Cognitive Training and Remediation Studies and a separate study. Approximately half the participants received CR and the rest were allocated to a control condition. All participants were assessed before and after therapy and at follow-up. Expressive negative symptoms and social amotivation symptoms scores were calculated from the Positive and Negative Syndrome Scale. WM was assessed with digit span and letter-number span tests.ResultsParticipants who received CR had a significant improvement in WM scores (d = 0.27) compared with those in the control condition. Improvements in social amotivation levels approached statistical significance (d = −0.19), but change in expressive negative symptoms did not differ between groups. WM change did not mediate the effect of CR on social amotivation.ConclusionsThe results suggest that a course of CR may benefit behavioural negative symptoms. Despite hypotheses linking memory problems with negative symptoms, the current findings do not support the role of this cognitive domain as a significant mediator. The results indicate that WM improves independently from negative symptoms reduction.

Objectives: Internationally, funders require stakeholder involvement throughout health technology assessment (HTA). We report successes, challenges, and lessons learned from extensive stakeholder involvement throughout a palliative care case study that demonstrates new concepts and methods for HTA.Methods: A 5-step “INTEGRATE-HTA Model” developed within the INTEGRATE-HTA project guided the case study. Using convenience or purposive sampling or directly / indirectly identifying and approaching individuals / groups, stakeholders participated in qualitative research or consultation meetings. During scoping, 132 stakeholders, aged ≥ 18 years in seven countries (England, Italy, Germany, The Netherlands, Norway, Lithuania, and Poland), highlighted key issues in palliative care that assisted identification of the intervention and comparator. Subsequently stakeholders in four countries participated in face–face, telephone and / or video Skype meetings to inform evidence collection and / or review assessment results. An applicability assessment to identify contextual and implementation barriers and enablers for the case study findings involved twelve professionals in the three countries. Finally, thirteen stakeholders participated in a mock decision-making meeting in England.Results: Views about the best methods of stakeholder involvement vary internationally. Stakeholders make valuable contributions in all stages of HTA; assisting decision making about interventions, comparators, research questions; providing evidence and insights into findings, gap analyses and applicability assessments. Key challenges exist regarding inclusivity, time, and resource use.Conclusion: Stakeholder involvement is feasible and worthwhile throughout HTA, sometimes providing unique insights. Various methods can be used to include stakeholders, although challenges exist. Recognition of stakeholder expertise and further guidance about stakeholder consultation methods is needed.
How Often Must We Re-Invent the Wheel? Reflections on the Most Efficient Structure of Prosecution Offices in International Courts and Why It is Not Generally Used
Authors: BIRN RUTH BETTINA 
Published: September 2017

AbstractAre historians or other country specialists needed in the investigation and prosecution of crimes under international law? Experiences at international tribunals, from the Nuremberg Trials to the present, offer different answers to this question. This article argues that country specialists are indispensable and demonstrates how, time and again, in international or national settings, practical necessities have led to structural models in which lawyers, investigators and country specialists work together. A ‘best practices’ model for interdisciplinary investigations adopted by a group of national and international prosecution units is presented in detail. When creating new international tribunals, the UN did not incorporate this model. What is needed for future tribunals is a structural framework of the Office of the Prosecutor, which includes country specialists.
The Job Market for Justice: Screening and Selecting Candidates for the International Court of Justice

Published: September 2017

AbstractOver the past few decades, states have granted greater independence and authority to international courts, yet still retain their ability to control who sits on the bench. This article examines how governments use their power of judicial nomination and appointment in the context of the International Court of Justice (ICJ) and assesses the relative influence of three factors on states’ vote choices for ICJ candidates: the candidates’ probability of (in)sensitivity to political considerations; their qualifications; and the role of interstate politics. Drawing on a new dataset of candidates nominated for election to the ICJ between 1949 and 2010, we demonstrate that electing states base their initial vote choices largely on the same set of factors within both bodies that elect ICJ judges: the United Nations General Assembly and Security Council. In particular, professional experiences signaling a probability of insensitivity to political considerations reduce a candidate's expected vote share. A candidate's qualifications, on the other hand, do not appear to make a considerable difference in winning more votes. Finally, the amount of support during the nomination stage is highly correlated with vote share, suggesting that considerable screening occurs prior to nomination and that the number of nominations received facilitates co-ordination of vote choice across states.
The multifaceted role of inhibitory interneurons in the dorsal lateral geniculate nucleus
Authors: COX CHARLES L. , BEATTY JOSEPH A. 
Published: September 2017

AbstractIntrinsic interneurons within the dorsal lateral geniculate nucleus (dLGN) provide a feed-forward inhibitory pathway for afferent visual information originating from the retina. These interneurons are unique because in addition to traditional axodendritic output onto thalamocortical neurons, these interneurons have presynaptic dendrites that form dendrodendritic synapses onto thalamocortical neurons as well. These presynaptic dendrites, termed F2 terminals, are tightly coupled to the retinogeniculate afferents that synapse onto thalamocortical relay neurons. Retinogeniculate stimulation of F2 terminals can occur through the activation of ionotropic and/or metabotropic glutamate receptors. The stimulation of ionotropic glutamate receptors can occur with single stimuli and produces a short-lasting inhibition of the thalamocortical neuron. By contrast, activation of metabotropic glutamate receptors requires tetanic activation and results in longer-lasting inhibition in the thalamocortical neuron. The F2 terminals are predominantly localized to the distal dendrites of interneurons, and the excitation and output of F2 terminals can occur independent of somatic activity within the interneuron thereby allowing these F2 terminals to serve as independent processors, giving rise to focal inhibition. By contrast, strong transient depolarizations at the soma can initiate a backpropagating calcium-mediated potential that invades the dendritic arbor activating F2 terminals and leading to a global form of inhibition. These distinct types of output, focal versus global, could play an important role in the temporal and spatial roles of inhibition that in turn impacts thalamocortical information processing.

AimThe aim of this study was to determine if the problem-solving therapy (PST) helps control metabolic variables in patients with type 2 diabetes mellitus (T2DM) who show depressive and anxiety symptoms.BackgroundT2DM is a chronic-degenerative multifactorial disease. It is considered one of the main public health problems in the world, and it represents an important social and economic burden. It is frequently associated with major depression and anxiety disorders, which are related with high glycated hemoglobin (HbA1c) concentrations and poor metabolic control.MethodWe initially included 123 patients diagnosed with T2DM from five primary care centers (PCC) in Mexico City. HbA1c, central glucose, and lipid profile were measured in each patient. In addition, the Kessler psychological distress scale (K-10), the Beck Depression Inventory, and the Beck Anxiety Inventory were applied at the beginning and, to those who continued, at the end of the PST, as well as four months later.FindingsIn total, 36 patients completed the PST and the follow-up. There was a significant decrease in depressive and anxiety symptoms (P&lt;0.001), as well as in total cholesterol (P=0.002), HbA1c(P=0.05), and low-density lipoprotein (LDL) (P=0.022). The PST helps reduce depressive and anxiety symptoms and may help stabilize glucose and cholesterol up to four months. Further studies on this area are recommended. If our findings are confirmed, the PST could help improve the quality of life of thousands of individuals with psychiatric-metabolic co-morbidity who only visit PCC.

Abstract
In Senegal, damage caused by insect pests is a major obstacle to seasonal stability and an increase in cabbage production. Little is known about the spatial and temporal distribution of cabbage pests, which makes the design of management recommendations to small-scale farmers challenging. The objectives of this study were to: (i) evaluate the status of insect pests observed in cabbage farmers’ fields; (ii) give information on the spatial and temporal distribution of key pests and (iii) assess the effect of temperature, insecticide applications, and host crop abundance on their incidence. A total of 116 cabbage fields were monitored for insect pests and related damage over four crop cycles, from October 2012 to May 2014, in the main vegetable producing area of Senegal (Niayes). The diamondback moth Plutella xylostella (L.) was by far the most important pest present in all the fields and with high levels of incidence (37.1% infested plants), particularly in the latter part of the dry season in the South of Niayes (50% infested plants). The cabbage webworm Hellula undalis (F.) was mainly observed in the early dry season in the south of Niayes, with an incidence of up to 12.5% infested plants. More surprising was the detection of the tomato fruit worm Helicoverpa armigera (Hübner), with damage of up to 9.4% of cabbage heads. The incidence of sucking pests such as whiteflies Bemisia tabaci (Gennadius), or aphids (including Lipaphis pseudobrassicae (Davis, 1914), Myzus persicae (Sulzer) or Brevicoryne brassicae (L.)) was generally low. The incidence of P. xylostella increased significantly with the number of insecticide applications, indicating that control deployed by growers was ineffective. The incidence of H. undalis did not depend on the number of insecticide applications, but significantly increased with host crop abundance and decreased with temperature. This study is a first step towards developing alternative pest management strategies in the framework of sustainable vegetable production systems.
Copying informal institutions: the role of British colonial officers during the decolonization of British Africa
Authors: SEIDLER VALENTIN 
Published: September 2017

AbstractInstitutional reforms in developing countries often involve copying institutions from developed countries. Such institutional copying is likely to fail, if formal institutions alone are copied without the informal institutions on which they rest in the originating country. This paper investigates the role of human actors in copying informal institutions. At independence, all British African colonies imported the same institution intended to safeguard the political neutrality of their civil services. While the necessary formal provisions were copied into the constitutions of all African colonies, the extent to which they were put into practice varies. The paper investigates the connection between the variation in the legal practice and the presence of British colonial officers after independence. A natural experiment around compensation payments to British officers explains the variation in the number of officers who remained in service after independence. Interviews with retired officers suggest that the extended presence of British personnel promoted the acceptance of imported British institutions among local colleagues.
Fehlbelastungen im Studium

Published: September 2017

Zusammenfassung. In zwei Studien wurde die aus dem Arbeitskontext stammende Irritationsskala an den universitären Kontext angepasst. Die studentische Irritationsskala erfasst die subjektiv wahrgenommene kognitive und emotionale Belastung im Studium. Im Vergleich zum Original wurden in einer ersten Studie in zwei Befragungen (N = 348, N = 121) für die Subskala emotionale Irritation zwei Items entfernt und eines neu formuliert. In der zweiten Studie (N = 903) wurde die zweifaktorielle Struktur der Skala mittels konfirmatorischer Faktorenanalyse bestätigt. Die internen Konsistenzen sind sehr gut (kognitive Irritation: α = .85, emotionale Irritation: α = .91). Die Zusammenhänge mit anderen Konstrukten fielen weitgehend erwartungsgemäß aus. Studiumsspezifische Belastungsfaktoren wie die wahrgenommene Prüfungsbelastung korrelierten signifikant mit mindestens einer der beiden Subskalen. Es steht somit ein ökonomisches und valides Verfahren zur Erkennung belastungsbezogener Beanspruchungsfolgen im Studium zur Verfügung.
News Consumption and Its Unpleasant Side Effect
Authors: Boukes Mark , Vliegenthart Rens 
Published: September 2017

Abstract. Following the news is generally understood to be crucial for democracy as it allows citizens to politically participate in an informed manner; yet, one may wonder about the unintended side effects it has for the mental well-being of citizens. With news focusing on the negative and worrisome events in the world, framing that evokes a sense of powerlessness, and lack of entertainment value, this study hypothesizes that news consumption decreases mental well-being via negative hedonic experiences; thereby, we differentiate between hard and soft news. Using a panel survey in combination with latent growth curve modeling (n = 2,767), we demonstrate that the consumption of hard news television programs has a negative effect on the development of mental well-being over time. Soft news consumption, by contrast, has a marginally positive impact on the trend in well-being. This can be explained by the differential topic focus, framing and style of soft news vis-à-vis hard news. Investigating the effects of news consumption on mental well-being provides insight into the impact news exposure has on variables other than the political ones, which definitively are not less societally relevant.

AbstractBackground:The effects of obesity surgery on serum and adipose tissue fatty acid (FA) profile and FA metabolism may modify the risk of obesity-related diseases.Methods:We measured serum (n=122) and adipose tissue (n=24) FA composition and adipose tissue mRNA expression of genes regulating FA metabolism (n=100) in participants of the Kuopio Obesity Surgery Study (KOBS, age 47.2±8.7 years, BMI 44.6±6.0, 40 men, 82 women) before and one year after obesity surgery. As part of the surgery protocol, all the subjects were instructed to add sources of unsaturated fatty acids, such as rapeseed oil and fatty fish, into their diet. The results were compared with changes in serum FA composition in 122 subjects from the Finnish Diabetes Prevention study (DPS) (age 54.3±7.1 years, BMI 32.2±4.6, 28 men, 94 women).Results:The proportion of saturated FAs decreased and the proportion of n-3 and n-6 FAs increased in serum triglycerides after obesity surgery (allP<0.002). Weight loss predicted changes in quantitative amounts of saturated FAs, monounsaturated FAs, n-3 and n-6 FAs in triglycerides (P<0.002 for all). Moreover, the changes in adipose tissue FAs reflected the changes in serum FAs, and some of the changes were associated with mRNA expression of elongases and desaturases in adipose tissue (allP<0.05). In line with this the estimated activity of elongase (18:1 n-7/16:1 n-7) increased significantly after obesity surgery in all lipid fractions (allP<4 × 10−7) and the increase in the estimated activity of D5D in triglycerides was associated with higher weight loss (r=0.415,P<2 × 10−6). Changes in serum FA profile were similar after obesity surgery and lifestyle intervention, except for the change in the absolute amounts of n-3 FAs between the two studies (P=0.044).Conclusions:Beneficial changes in serum and adipose tissue FAs after obesity surgery could be associated with changes in endogenous metabolism and diet.
