UNCERTAINTY AND ORIENTATION TOWARDS ERRORS IN TIMES OF CRISIS. THE IMPORTANCE OF BUILDING CONFIDENCE, ENCOURAGING COLLECTIVE EFFICACY

that is affecting the organizational behavior reflected by individuals, teams and organizations. In the crisis, individuals work under the threat of the insecurity of maintaining their jobs, the distrust and competition with members of their team in the event of a possible layoff, uncertainty about the future of the organization or the evaluation of the attractiveness of their characteristics of employability in the labor market (Tabernero, Briones & Arenas, 2011). Rosen, Ivanova and Knauper (2014) argue that maintaining a state of uncertainty implies distrust regarding the occurrence of an expected outcome, which affects the motivation to achieve a goal. It has also been shown that living with high levels of uncertainty is associated with a higher likelihood of negative physiological and psychological consequences of stress and greater anxiety, depression and lower quality of life (Arce, 2012; Stuckler & Basu, 2013). Many decisions are made under stress—choosing the correct answer on a test or an emergency exit—and many of these decision-making situations generate stressful solutions in themselves—stock exchange dealers who make decisions that put other people’s money at risk (Starcke & Brand, 2012). Thus, stress and decision-making are inextricably linked, both at the behavioral level and the neuronal level. Being exposed to stress and its trigger reactions influences the quality of decisions and can have a negative effect on health. And if the context in which decisions are made makes us feel excluded, the decisions can be irrational and even self-destructive (Briones, Tabernero & Arenas, 2007). For this reason, a number of articles have been appearing in the news related to the cognitive and affective variables that determine decision-making in crisis. Recently, the newspaper El País (2014) presented a paper entitled “Making business decisions without being carried away by emotions“ and the editorial Conecta (2013) published a book entitled “Your money and your brain.

Client Violence and Its Negative Impacts on Work Attitudes of Child Protection Workers Compared to Community Service Workers

This study investigated the prevalence of client violence toward child protection workers and its negative impacts on the work attitudes of those workers compared with community service workers in South Korea. This study is based on the assumption that child protection workers are more vulnerable to violence than are community service workers because of the unique characteristics of the roles they play. Results of the data, drawn from a sample of 413 child protection workers and community service workers, found that client violence was more prevalent against child protection workers and that the negative impacts of this violence on work attitudes were more clearly highlighted for child protection workers. Based on the results of this study, implications for preventing client violence and lessening its negative impacts on work attitudes of child protection workers were identified.
A Meta-Analytic Review of Corporate Social Responsibility and Corporate Financial Performance

The relationship between corporate social responsibility (CSR) and corporate financial performance (CFP) has long been a central and contentious debate in the literature. However, prior empirical studies provide indefinite conclusions. The purpose of this study is to review systematically and quantify the CSR–CFP link in a meta-analytic framework. Based on 119 effect sizes from 42 studies, this study estimates that the overall effect size of the CSR–CFP relationship is positive and significant, thus endorsing the argument that CSR does enhance financial performance. Furthermore, this work sheds light on the causal relationship between CSR and CFP. Subsequent financial performance is associated with prior social responsibility, while the reverse direction is not supported. This finding supports the instrumental stakeholder theory. As predicted, the meta-analysis results indicate that the measurement strategies of the two key constructs of CSR and CFP explain some variations of the CSR–CFP relationship. Last, this study examines the moderating effect of the environmental context on the CSR–CFP link. This work proposes that CSR in the developed world, with a relatively mature institutional system and efficient market mechanism, will be more visible than CSR in the developing world. The results show that the CSR–CFP relationship is stronger for firms from advanced economies than for firms from developing economies.
Sulfoacetate Is Degraded via a Novel Pathway Involving Sulfoacetyl-CoA and Sulfoacetaldehyde in Cupriavidus necator H16

Bacterial degradation of sulfoacetate, a widespread natural product, proceeds via sulfoacetaldehyde and requires a considerable initial energy input. Whereas the fate of sulfoacetaldehyde in Cupriavidus necator (Ralstonia eutropha) H16 is known, the pathway from sulfoacetate to sulfoacetaldehyde is not. The genome sequence of the organism enabled us to hypothesize that the inducible pathway, which initiates sau (sulfoacetate utilization), involved a four-gene cluster (sauRSTU; H16_A2746 to H16_A2749). The sauR gene, divergently orientated to the other three genes, probably encodes the transcriptional regulator of the presumed sauSTU operon, which is subject to inducible transcription. SauU was tentatively identified as a transporter of the major facilitator superfamily, and SauT was deduced to be a sulfoacetate-CoA ligase. SauT was a labile protein, but it could be separated and shown to generate AMP and an unknown, labile CoA-derivative from sulfoacetate, CoA, and ATP. This unknown compound, analyzed by MALDI-TOF-MS, had a relative molecular mass of 889.7, which identified it as protonated sulfoacetyl-CoA (calculated 889.6). SauS was deduced to be sulfoacetaldehyde dehydrogenase (acylating). The enzyme was purified 175-fold to homogeneity and characterized. Peptide mass fingerprinting confirmed the sauS locus (H16_A2747). SauS converted sulfoacetyl-CoA and NADPH to sulfoacetaldehyde, CoA, and NADP+, thus confirming the hypothesis.
A process of rumour scotching on finite populations

Rumour spreading is a ubiquitous phenomenon in social and technological networks. Traditional models consider that the rumour is propagated by pairwise interactions between spreaders and ignorants. Only spreaders are active and may become stiflers after contacting spreaders or stiflers. Here we propose a competition-like model in which spreaders try to transmit an information, while stiflers are also active and try to scotch it. We study the influence of transmission/scotching rates and initial conditions on the qualitative behaviour of the process. An analytical treatment based on the theory of convergence of density-dependent Markov chains is developed to analyse how the final proportion of ignorants behaves asymptotically in a finite homogeneously mixing population. We perform Monte Carlo simulations in random graphs and scale-free networks and verify that the results obtained for homogeneously mixing populations can be approximated for random graphs, but are not suitable for scale-free networks. Furthermore, regarding the process on a heterogeneous mixing population, we obtain a set of differential equations that describes the time evolution of the probability that an individual is in each state. Our model can also be applied for studying systems in which informed agents try to stop the rumour propagation, or for describing related susceptible–infected–recovered systems. In addition, our results can be considered to develop optimal information dissemination strategies and approaches to control rumour propagation.
A Comparison of FFS Disk Allocation Policies

The 4.4BSD file system includes a new algorithm for allocating disk blocks to files. The goal of this algorithm is to improve file clustering, increasing the amount of sequential I/O when reading or writing files, thereby improving file system performance. In this paper we study the effectiveness of this algorithm at reducing file system fragmentation. We have created a program that artificially ages a file system by replaying a workload similar to that experienced by a real file system. We used this program to evaluate the effectiveness of the new disk allocation algorithm by replaying ten months of activity on two file systems that differed only in the disk allocation algorithms that they used. At the end of the ten month simulation, the file system using the new allocation algorithm had approximately half the fragmentation of a similarly aged file system that used the traditional disk allocation algorithm. Measuring the performance difference between the two file systems by reading and writing the same set of files on the two systems showed that this decrease in fragmentation improved file write throughput by 20% and read throughput by 32%. In certain test cases, the new allocation algorithm provided a performance improvement of greater than 50%.
Karyotypic conservatism in samples of Characidium cf. zebra (Teleostei, Characiformes, Crenuchidae): Physical mapping of ribosomal genes and natural triploidy

Basic and molecular cytogenetic analyses were performed in specimens of Characidium cf. zebra from five collection sites located throughout the Tietê, Paranapanema and Paraguay river basins. The diploid number in specimens from all samples was 2n = 50 with a karyotype composed of 32 metacentric and 18 submetacentric chromosomes in both males and females. Constitutive heterochromatin was present at the centromeric regions of all chromosomes and pair 23, had additional interstitial heterochromatic blocks on its long arms. The nucleolar organizer regions (NORs) were located on the long arms of pair 23, while the 5S rDNA sites were detected in different chromosomes among the studied samples. One specimen from the Alambari river was a natural triploid and had two extra chromosomes, resulting in 2n = 77. The remarkable karyotypic similarity among the specimens of C. cf. zebra suggests a close evolutionary relationship. On the other hand, the distinct patterns of 5S rDNA distribution may be the result of gene flow constraints during their evolutionary history.
Microfabricated coupled inductors for DC-DC converters for microprocessor power delivery

High-current, low-voltage power converters with fast transient response are needed for powering digital systems such as microprocessors. Microfabricated coupled inductors for such power converters are discussed. A four-phase microfabricated magnetic structure with 14 nH of inductance per phase has been fabricated for a 5 MHz, 5 V-to-1 V, 10 A dc-dc converter. The first prototype devices have been built with nickel-iron (NiFe) cores and copper conductors on a silicon substrate. Small-signal measurements on the inductors have been performed and predictions have been confirmed. A model for analyzing the performance of coupled inductors is presented. The devices have been implemented in a prototype converter and the measured performance is compared with the predicted results.
Dynamic pricing and profit maximization for the cloud with geo-distributed data centers

Cloud providers often choose to operate datacenters over a large geographic span, in order that users may be served by resources in their proximity. Due to time and spatial diversities in utility prices and operational costs, different datacenters typically have disparate charges for the same services. Cloud users are free to choose the datacenters to run their jobs, based on a joint consideration of monetary charges and quality of service. A fundamental problem with significant economic implications is how the cloud should price its datacenter resources at different locations, such that its overall profit is maximized. The challenge escalates when dynamic resource pricing is allowed and long-term profit maximization is pursued. We design an efficient online algorithm for dynamic pricing of VM resources across datacenters in a geo-distributed cloud, together with job scheduling and server provisioning in each datacenter, to maximize the profit of the cloud provider over a long run. Theoretical analysis shows that our algorithm can schedule jobs within their respective deadlines, while achieving a time-average overall profit closely approaching the offline maximum, which is computed by assuming that perfect information on future job arrivals are freely available. Empirical studies further verify the efficacy of our online profit maximizing algorithm.
Scheduling to Optimize Cache Utilization for Non-Volatile Main Memories

In power and size sensitive embedded systems, non-volatile memories (NVMs) are replacing DRAM as the main memory since they have higher density, lower static power consumption, and lower costs. Unfortunately, these technologies are limited by their endurance and long write latencies. To minimize the main memory access time and extend the lifetime of the NVM, we optimally schedule tasks by an ILP formulation. We also present a heuristic, Concatenation Scheduling, to solve large problems in a reasonable amount of time. Our experimental results show that when compared with list scheduling, concatenation scheduling can reduce the total memory access time by an average of 9.99% and increase the lifetime of the NVM by 26.66%. When compared with list scheduling, ILP can reduce the total memory access time by an average of 12.39% and increase the lifetime of the NVM by 38.74%.
Prescriptions for measuring and transporting local angular momenta in general relativity

For observers in curved spacetimes, elements of the dual space of the set of linearized Poincare transformations from an observer’s tangent space to itself can be naturally interpreted as local linear and angular momenta. We present an operational procedure by which observers can measure such quantities using only information about the spacetime curvature at their location. When applied by observers near spacelike or null infinity in stationary, vacuum, asymptotically flat spacetimes, there is a sense in which the procedure yields the well-defined linear and angular momenta of the spacetime. We also describe a general method by which observers can transport local linear and angular momenta from one point to another, which improves previous prescriptions. This transport is not path independent in general, but becomes path independent for the measured momenta in the same limiting regime. The transport prescription is defined in terms of differential equations, but it can also be interpreted as parallel transport in a particular direct-sum vector bundle. Using the curvature of the connection on this bundle, we compute and discuss the holonomy of the transport law. We anticipate that these measurement and transport definitions may ultimately prove useful for clarifying the physical interpretation of the Bondi-Metzner-Sachs charges of asymptotically flat spacetimes.
Changes in developmental body weight as a function of toluene exposure

Inhalant abuse is a globally prevalent health issue with particular concerns about substance-abusing pregnant women. In both animal models and clinical case reports of toluene exposure, the primary physiological outcome measure of prenatal inhalant exposure is low birth weight (BW). However, the effect of prenatal toluene exposure on animal BW varies widely in the literature. To clarify this effect and investigate possible design moderators of pup BW, a systematic review and meta-analytic techniques were applied to the existing peer-reviewed animal literature of prenatal and postnatal exposure models to the inhaled solvent toluene. Of 288 studies screened, 24 studies satisfied the inclusion criteria. Evaluation of these studies indicated that toluene exposure was negatively associated with pup BW (d = −0.39), with external inhaled concentration, route of administration, day of weighing, and toluene exposure magnitude moderating this association. Investigators doing animal studies should be cognizant of these factors before investigating the reproductive and developmental outcomes associated with prenatal and postnatal toluene exposure.
First-Principles Calculations of the Adsorption Property of C6H7N and C7H9N on Pd-doped TiO2 Anatase (1 0 1)

In this work, we proposed a novel Pd-doped TiO2 anatase (1 0 1), material as the gas sensing material to detect typical lung cancer volatile organic compounds: aniline (C6H7N) and o-toluidine (C7H9N). After analyse the adsorption structure, charge transfer, the density of states and band structure, it is found that Pd-TiO2 presents good gas sensing properties to C6H7N and C7H9N. The single doped Pd atom acts as the active site to interact with the gas molecules, which causes the electron redistribution and the change of conductivity of adsorption system. According to the different change characteristics of conductivity upon different gas molecules adsorption, Pd-TiO2 material can not only realize high gas sensitivity, but also realizes selectivity to C6H7N and C7H9N. The calculation results play a guiding role to prepare high-performance Pd-TiO2 material gas sensor in experiment.
PKR Inhibition Rescues Memory Deficit and ATF4 Overexpression in ApoE ε4 Human Replacement Mice

Sporadic Alzheimer's disease (AD) is an incurable neurodegenerative disease with clear pathological hallmarks, brain dysfunction, and unknown etiology. Here, we tested the hypothesis that there is a link between genetic risk factors for AD, cellular metabolic stress, and transcription/translation regulation. In addition, we aimed at reversing the memory impairment observed in a mouse model of sporadic AD. We have previously demonstrated that the most prevalent genetic risk factor for AD, the ApoE4 allele, is correlated with increased phosphorylation of the translation factor eIF2α. In the present study, we tested the possible involvement of additional members of the eIF2α pathway and identified increased mRNA expression of negative transcription factor ATF4 (aka CREB2) both in human and a mouse model expressing the human ApoE4 allele. Furthermore, injection of a PKR inhibitor rescued memory impairment and attenuated ATF4 mRNA increased expression in the ApoE4 mice. The results propose a new mechanism by which ApoE4 affects brain function and further suggest that inhibition of PKR is a way to restore ATF4 overexpression and memory impairment in early stages of sporadic AD. SIGNIFICANCE STATEMENT ATF4 mRNA relative quantities are elevated in ApoE4 allele carriers compared with noncarrier controls. This is true also for the ApoE ε4 human replacement mice. ApoE4 mice injected with PKR inhibitor (PKRi) demonstrate a significant reduction in ATF4 expression levels 3 h after one injection of PKRi. Treatment of ApoE4 human replacement mice with the PKRi before learning rescues the memory impairment of the ApoE4 AD model mice. We think that these results propose a new mechanism by which ApoE4 affects brain function and suggest that inhibition of PKR is a way to restore memory impairment in early stages of sporadic AD.
Teaching Grammar and Testing Grammar in the English Primary School: The Impact on Teachers and their Teaching of the Grammar Element of the Statutory Test in Spelling, Punctuation and Grammar (SPaG)

Abstract The research examined the impact on teachers of the grammar element of a new statutory test in Spelling, Punctuation and Grammar (SPaG) in primary schools in England. The research aimed to evaluate the nature and the extent of changes to the teaching of grammar and to wider literacy teaching since the introduction of the test in 2013. The research explored teachers’ responses to teaching grammar to a statutory test format, and how teachers implemented rapid curriculum change in their classrooms. The research sought to learn the perspectives of teachers as they adjusted to new English assessments and new expectations for children’s language in the primary school. This paper draws on teacher interviews (n = 16) and an online survey of teaching staff (n = 170). Teachers discuss their knowledge, understanding and enjoyment of grammar at their own level, and their skills for teaching pupils; they also discuss their observations of how pupils have responded to explicit grammar teaching and the grammar test. The data give some insights into the processes for teachers of applying new requirements for teaching and testing grammar, and how teachers strive to make grammar accessible to children. The findings discussed in this paper are: (1) since the introduction of the statutory SPaG test in primary schools, time spent teaching decontextualised and contextualised grammar has increased significantly; (2) grammar is now taught explicitly and formally as a classroom literacy routine; (3) the test format influences grammar teaching content and approaches; (4) teachers observe that pupils enjoy learning grammar and taking the test; (5) teachers disagree about the extent to which explicit grammar teaching and testing have a positive impact on pupils’ language and literacy skills; (6) teachers feel more confident about teaching grammar.
Factors that influence engagement in pre-proceedings practice: presenting the roles of professionals working within the family justice system through personal narratives

Public discourse around changes introduced as part of a drive to tackle spending on welfare, reflect a less than tolerant attitude towards welfare generally, but more specifically towards parents who require state involvement to care safely for their children. The introduction of a deadline of 26 weeks for the completion of care proceedings, together with a clear steer to resolve disputes wherever possible prior to making an application to court has introduced further instrumental approaches to working with parents. In this paper we explore practitioner experiences and understandings of working within the new legislative frameworks and consider the dominant cultural narratives they are working within. However, in some cases professionals felt able to challenge the economic narrative of the pre-proceedings protocol, and they experienced the legal and policy changes as an opportunity to engage in a helping alliance with families with the provision of support that otherwise they would not have been able to offer.
Structural Types for the Factorisation Calculus

The factorisation calculus of Jay and Given-Wilson, a fundamental model of pattern matching, introduces the factorisation combinator, whose behaviour is conditional on the structure of its arguments. This combinator is typeable with polymorphic types such as System F types; this system does not have the property of type assignment decidability. We develop a new type system for the factorisation calculus, the structural type system, which augments Curry types with structural modifiers. These structural modifiers carry information sufficient to type the factors of an application solely from the type of the application itself. With this, we are able to develop a principal types algorithm, and show soundness and completeness properties. We apply our type system to the theory of typed self-interpretation. Jay and Palsberg introduce an extension to the factorisation calculus which supports typed self-interpretation, again without decidable type assignment. We modify their calculus in order to preserve the properties of the principal types algorithm while retaining the self-interpreting terms. In this way we show the existence of a self-recogniser and self-enactor for a statically-typed calculus with decidable type inference.
