Relative Performance Feedback Information and Happiness

This paper studies the effect of providing relative performance feedback information, when agents are rewarded according to their absolute performance, on individual performance, as well as on individual affective response. In a laboratory set-up, agents perform a real effort task and are asked to rate their happiness , arousal and feeling of dominance . Control subjects learn only their absolute performance, while the treated subjects additionally learn whether they are performing above or below the average subject in the group. Performance is 17 percent higher when relative performance feedback is provided. Furthermore, although the feedback increases the performance independent of the content of the information (i.e. performing above or below the average), the content is determinant for the affective response. When subjects are treated, the inequality in happiness and feelings of dominance between those subjects performing above and below the average increases by 11 and 6 percentage points, respectively.
Regular solutions to the fractional Euler alignment system in the Besov spaces framework

We here construct (large) local and small global-in-time regular unique solutions to the fractional Euler alignment system in the whole space [Formula: see text], in the case where the deviation of the initial density from a constant is sufficiently small. Our analysis strongly relies on the use of Besov spaces of the type [Formula: see text], which allow to get time independent estimates for the density even though it satisfies a transport equation with no damping. Our choice of a functional setting is not optimal but aims at providing a transparent and accessible argumentation.
Older people , video games and the European French-language press A topic model approach on a study about deviance , discipline and self-improvement

Over the past few years, the French mainstream press has paid more and more attention to “silver gamers”, adults over sixty who play video games. Th is article investigates the discursive and normative paradigms that underlie the unexpected enthusiasm of the French mainstream press for older adults who play video games. We use mixed methods on a corpus of French, Swiss and Belgian articles that mention both older people and video games. First, we produce topics, that is, sets of words related by their meanings and identifi ed with a Bayesian statistical algorithm. Second, we cross the topic model results with a discursive analysis of selected articles. We preface the topic modeling’s conclusions with a discussion of the representations of older people and video games in European French-language mainstream media. Our analysis explores how the press coverage of older people who play video games simultaneously erases moral panic about video games and reinforces the discourse of “successful ageing”.
Potential for the development of aquaculture in Africa

Aquaculture production in Africa has remained low despite the huge potential that exists on the continent. In order for this potential to be realized, it is necessary to refocus the direction of aquaculture development. This paper concludes that for further growth to occur it is necessary to: (i) widen the range of production systems; (ii) increase production intensities and efficiencies; (iii) develop management technologies for indigenous species that target local niche markets; (iv) put more emphasis on marketing and processing of high value products; (v) promote policy research on how aquaculture production can respond to changing macroeconomic policies; and (vi) accelerate the disengagement of government from activities that can best be done by the private sector.
The Need for a Software Process Improvement Model for the Medical Device Industry

Software is becoming an increasingly important aspect of medical devices and medical device regulation. Software enables highly complex systems to be built. However, complexity is the enemy of safety, therefore strict adherence to well documented processes is important within the domain of medical device software. Medical devices can only be marketed if compliance and approval from the appropriate regulatory bodies (e.g. the Food and Drug Administration (FDA)) is achieved. This paper outlines the development of a software process improvement (SPI) model specifically for the medical device industry. The paper details how medical device regulations may be satisfied by adopting relevant practices from the Capability Maturity Model Integration ( CMMI®).

Preferences for Alternative-Fuel Vehicles of Lease Car Drivers in the Netherlands

In this paper we aim to get insight into preferences of Dutch lease car drivers for alternative fuel vehicles (AFVs) and their characteristics. Since AFVs are either not yet available on the market or have only very limited market shares, we have to rely on stated preference research. We perform a state-of-the-art conjoint analysis, based on data obtained through an online choice experiment among Dutch lease car drivers. Results show that under current tax regulations the average lease car driver is indifferent between the conventional technology, flexifuel and the hybrid car, while negative preferences exist for the plug-in hybrid, the electric and the fuel cell car. When current tax regulations would be abolished, strong negative preferences would result for all AFV’s, and especially for the electric and fuel cell car. Increases in driving range, reductions in refuelling time, and reductions in additional detour time for reaching an appropriate fuel station, increase AFV preferences substantially. On average the gap between conventional technologies and AFVs remains large, however. We also find that there is considerable heterogeneity in preferences of lease car drivers, and that various market segments and potential early adopters can be identified. In this respect the most interesting finding is that preferences for electric and fuel cell cars decrease substantially, and willingness to pay for driving range increases substantially, when annual mileage increases. Annual mileage also has a substantial impact on sensitivity to monthly costs. We therefore use simulations to assess market shares of electric and fuel cell cars for different annual mileage categories. We find that people with a relatively low annual mileage are more likely to adopt than people with a relatively high annual mileage, regardless of driving range and monthly costs. For the fuel cell car we find similar results, although when driving range is high and cost differences are large, lease car drivers with a high annual mileage appear more likely to adopt a fuel cell car than those with a relatively low annual mileage.
Structural and magnetic characterization of Co 2+ substituted nano structured Copper-Zinc spinel ferrite

Nano particles of Cu0.61-xCoxZn0.39Fe2O4 (0 ≤ x ≤ 0.5) synthesized through sol-gel auto combustion method. Nitrates of elements and citric acid are used as starting materials. X-ray Diffraction, Thermo Gravimetric Analysis and Vibrating Sample Magnetometer are used to analyze the properties. Effect of variation in the Co substitution and its impact on particle size, lattice constant, density, cation distribution, ferritization temperature, associated water content, magnetic properties like saturation magnetization(MS), coercivity(HC) and remanent magnetization(Mr) is observed. Lattice parameter increases with increasing Co +2 concentration whereas X-ray density, bulk density decreases with the Co +2 content. In Cation distribution the Co and Cu ion show preference towards octahedral B-site, Zn occupy A site whereas Fe occupy both A and B site. Cation redistribution takes place for x > 0.3. Saturation magnetization increases from (x ≤ 0.3). For x > 0.3, Ms decreases suggesting that significant canting exists at B site. However, coercivity, magnetocrystalline anisotropy and remanant magnetization increases with the Co 2+ substitution.
Competency Management: Balancing Between Commitment and Control **

This study investigated the relationships between commitment and control approaches and the use of competency management by adopting the theory of planned behavior. Questionnaires were filled out by 43 human resource experts working in different organizations. We expected components of the theory of planned behavior to mediate the relationship between commitment and control approaches and the use of competency management (behavior). Regression analysis showed that perceived behavioral control mediated the relation between commitment approach and behavior. Furthermore, the data revealed that attitude towards competency management was more positive and perceived behavioral control was higher when competency management was implemented with a commitment instead of a control approach. Subjective norm was strongly related to behavior. Based on the results, for competency management to be frequently used, we argue for increased behavioral control, and for an organizational climate in which competency management is widely accepted.
The effects of high liquid water content on thunderstorm charging

Charge transfer to a riming graupel target during interactions with ice crystals has been investigated in the laboratory. When liquid water contents sufficiently high to cause wet growth are achieved, the charge transfer falls to values which are insignificant to thunderstorm electrification. The implications of this null result to a recent analysis of thunderstorm-charging processes by Williams et al. (1991) are discussed.

TRIGGERED STAR FORMATION AROUND MID-INFRARED BUBBLES IN THE G8.14+0.23 H ii REGION

Mid-infrared shells or bubbles around expanding H ii regions have received much attention due to their ability to initiate a new generation of star formation. We present multi-wavelength observations around two bubbles associated with a southern massive star-forming region G8.14+0.23, to investigate the triggered star formation signature on the edges of the bubbles by the expansion of the H ii region. We have found observational signatures of the collected molecular and cold dust material along the bubbles and the 12CO(J = 3–2) velocity map reveals that the molecular gas in the bubbles is physically associated around the G8.14+0.23 region. We have detected 244 young stellar objects (YSOs) in the region and about 37% of these YSOs occur in clusters. Interestingly, these YSO clusters are associated with the collected material on the edges of the bubbles. We have found good agreement between the dynamical age of the H ii region and the kinematical timescale of bubbles (from the 12CO(J = 3–2) line data) with the fragmentation time of the accumulated molecular materials to explain possible “collect and collapse” process around the G8.14+0.23 region. However, one cannot entirely rule out the possibility of triggered star formation by compression of the pre-existing dense clumps by the shock wave. We have also found two massive embedded YSOs (about 10 and 22 M☉) which are associated with the dense fragmented clump at the interface of the bubbles. We conclude that the expansion of the H ii region is also leading to the formation of these two young massive embedded YSOs in the G8.14+0.23 region.
The metabolic syndrome of ω3-depleted rats. I. Liver data

Second-generation rats depleted in long-chain polyunsaturated omega3 fatty acids were recently proposed as a novel animal model for the metabolic syndrome. In the present study, a dietary deprivation of omega3 acids for 3-7 months was found sufficient to provoke in 6-week-old normal rats the same alteration of the fatty acid content and profile of liver phospholipids and triglycerides as that otherwise prevailing in the second-generation omega3-depleted rats, with emphasis on a severe decrease in their omega3 fatty acid content, alterations in the relative contribution of and ratio between selected long-chain polyunsaturated omega6 fatty acids, saturated and monodesaturated fatty acids and precursors of nervonic acid, and liver steatosis. When the omega3-depleted rats were exposed, after the first 7 months of the present experiments and for 2-4 weeks to a diet supplemented with 5% (w/w) flaxseed oil, most of these hepatic variables returned towards or beyond control values. In both the omega3-depleted rats and control animals, however, the eventual exposure to the flaxseed oil-enriched diet failed to suppress liver steatosis and, on the contrary, provoked a further increase in liver triglyceride content. It is proposed, therefore, that the present approach represents a simple and realistic animal model to study the consequences of omega3-depletion. Moreover, the results suggest that to oppose such consequences, e.g. liver steatosis, it may be necessary to combine the dietary supply of omega3 acids with a suitable control of food intake, in both qualitative and quantitative terms.
De inzetbaarheid van mannelijke en vrouwelijke werknemers : kenmerken van invloed

Verslag van een verkennend onderzoek onder 2501 Nederlandse werknemers naar de kenmerken die een rol spelen bij de inzetbaarheid van mannelijke en vrouwelijke werknemers. Het werken aan de interne inzetbaarheid blijkt bij zowel mannen als vrouwen toe te nemen als zij werken in een bedrijf met een ondernemingsraad, op basis van een vaste aanstelling en in een hogere functie. Bij mannen leiden een hogere leeftijd en het werken in een klein bedrijf tot minder activiteit. Bij vrouwen hebben een deeltijdaanstelling en de zorg voor jonge kinderen een negatieve invloed. De externe mobiliteit blijkt bij mannen en vrouwen lager als zij een vaste aanstelling of een hogere leeftijd hebben. Verder zijn mannen uit bedrijven met een OR minder mobiel en wisselen vrouwen met een hogere opleiding juist vaker van werkgever. Het inzetbaarheidsbeleid van werkgevers blijkt zich primair te richten op vaste medewerkers die in een volledige baan en in hogere functies werken. Werknemers die hiervan afwijken, lopen daardoor een achterstand op.
On the Flow of $\Box R$ Weyl-Anomaly

An important aspect of Weyl anomalies is that they encode information on the irreversibility of the renormalisation group flow. We consider, $\Delta \bar b = \bar{b}^{\textrm{UV}} - \bar{b}^{\textrm{IR}}$, the difference of the ultraviolet and infrared value of the $\Box R$-term of the Weyl anomaly. The quantity is related to the fourth moment of the trace of the energy momentum tensor correlator for theories which are conformal at both ends. Subtleties arise for non-conformal fixed points as might be the case for infrared fixed points with broken chiral symmetry. Provided that the moment converges, $\Delta \bar{b}$ is then automatically positive by unitarity. Written as an integral over the renormalisation scale, flow-independence follows since its integrand is a total derivative. Furthermore, using a momentum subtraction scheme (MOM) the 4D Zamolodchikov- metric is shown to be strictly positive beyond perturbation theory and equivalent to the metric of a conformal manifold at both ends of the flow. In this scheme $\bar{b}(\mu)$ can be extended outside the fixed point to a monotonically decreasing function. The ultraviolet finiteness of the fourth moment enables us to define a scheme for the $\delta {\cal L} \sim b_0 R^2$-term, for which the $R^2$-anomaly vanishes along the flow. In the MOM- and the $R^2$-scheme, $\bar{b}(\mu)$ is shown to satisfy a gradient flow type equation. We verify our findings in free field theories, higher derivative theories and extend $\Delta \bar{b}$ and the Euler flow $\Delta \beta_a$ for a Caswell-Banks-Zaks fixed point for QCD-like theories to next-to-next-to leading order using a recent $\langle G^2G^2 \rangle$-correlator computation.
A 2400 yr Mesoamerican rainfall reconstruction links climate and cultural change

Droughts are a recurring feature of Mexican climate, but few high-resolution data are available to test for climate-change forcing of Mesoamerican civilizations. We present a quantitative 2400 yr rainfall reconstruction for the Basin of Mexico, from a precisely dated and highly resolved speleothem, that documents highly variable rainfall over the past 2400 yr. Dry conditions peaked during a 150-yr-long late Classic (ca. 600–900 CE) (Common Era) mega drought that culminated at 770 CE which followed centuries of climatic drying that spanned the fall of the city of Teotihuacan ca. 550 CE. The wettest conditions in the 1450s CE were associated with fl ooding in the Basin of Mexico. Our data suggest that rainfall variability was likely forced by the El Nino–Southern Oscillation, and impacts on spring-fed irrigation agriculture may have been a stressor on Mesoamerican civilizations.
On Ext2 between Weyl modules for quantum GLn

In the study of highest weight categories, the class of Weyl modules Δ(λ) and their duals ∇(λ) are of central interest; this is for example motivated by the problem of finding the characters of the simple modules. Weyl modules form the building blocks for the category [Fscr ](Δ), whose objects have a filtration 0 = M0 [les ] M1 [les ] … [les ] Mi−1 [les ] Mi = M with quotients isomorphic to Δ(λ) for various λ. Knowing Extr(Δ(λ), Δ(μ)) is essential for the understanding of this category. In [3, 13], we determined Ext1 for Weyl modules of SL(2, k) and q-GL(2, k) over an infinite field k of characteristic p > 0. Here we are able to extend these results to determine Ext2 for Weyl modules in both these cases (see Theorem 4 · 6). Moreover, this also gives Ext2 between any pair of Weyl modules Δ(λ), Δ(μ) for q-GL(n, k) (where n [ges ] 2) such that both λ and μ have at most two rows or two columns, or where they differ by some multiple of a simple root (see Section 7). Consider (for simplicity) polynomial representations of degree d for GL(n, k). A partition of d which has at most two rows is uniquely determined by the difference in the row lengths, which we use as a label for the partition. In this case our main result is
Subaltern studies: Advancing critical theory in ICT4D

Critical research has been advocated as capable to uncover multiple contradictions in ICT-induced development processes. This paper explores the potential of subaltern studies to contribute to the generation of critical theory in ICT4D. Following the postcolonial thought of Partha Chatterjee, the paper proposes a vision of subalternity centred on technologies of rule that concur to devoicing the marginalised. The theory is used to examine the computerisation of a large Indian social protection scheme, illustrating how processes of digitalisation, formally aimed at the empowerment of recipients, actually resulted in the systematic crystallisation of alienating power structures in the programme. This resulted in the further de-voicing of the wageseekers that the scheme should have empowered, casting doubt on the image of a pro-poor “digital India” represented in mainstream narratives. Used as analytical framework, subalternity theory makes it possible to represent the views of the devoiced and marginalised, hence contributing to enacting the emancipatory purpose of critical theory in ICT4D.
Safety management in repair, maintenance, minor alteration, and addition works : knowledge management perspective

Safety of repair, maintenance, alteration, and addition (RMAA) works have long been neglected because RMAAworks are often minute and only last for a short period of time. With rising importance of the RMAA sector in many developed societies, safety of RMAA works has begun to draw attention. Many RMAA contracting companies are small- and medium-sized enterprises (SMEs) that do not have comprehensive safety management systems. Existing safety legislation and regulations for new construction sites are not fully applicable to RMAAworks. Instead of relying on explicit and well-established safety systems, tacit safety knowledge plays an extremely important role in RMAA projects. To improve safety of RMAAworks, safety knowledge should be better managed. However, safety knowledge is difficult to capture in RMAA works. This study aims to examine safety management practices of RMAA contracting companies to see how safety knowledge of RMAA projects is managed. Findings show that RMAA contracting companies undertaking large-scale RMAA projects have more initiatives of safety management. Safety management of small-scale RMAA works relies heavily on the motivation of site supervisors and self-regulation of workers. Better tacit knowledge management improves safety performance. To enhance safety capability of RMAA contracting companies, a knowledge sharing culture should be cultivated. The government should provide assistance to SMEs to implement proper safety management practices in small-sized projects. Potentials of applying computer software technology in RMAA projects to capture, store, and retrieve safety information should be explored. Employees should be motivated to share safety knowledge by giving proper recognition to those who are willing to share.
