Aim/Purpose: The main aim of this study is to identify the factors that influence the continuance intention of use of innovative systems by non-academic employees of a private university and associated academic institutions in Bangladesh. Background: The targeted academic institutions have introduced many new online services aimed at improving students’ access to information and services, including a new online library, ERP or online forum, and the jobs-tracking system (JTS). This research is focused only on the JTS for two reasons. First, it is one of the most crucial systems for the Daffodil Family, as it enables efficient working across many institutes spread across the country and abroad. Second, it is employed in a wide variety of organisational institutes, not just the university. This study aims to discover negative factors that lead to a decrease in users’ intentions to continue using the system. The ultimate goal is to improve the motivation among administrative staff to use technology-related innovation by reducing or eliminating the problems. Methodology: G* power analysis was employed to determine the expected sample size. A questionnaire survey was conducted of 211 users of a new job tracking system from a private university in Bangladesh, to collect data for testing the suggested research model. The data was analysed using the structural equation technique, which is a powerful multivariate analysis mechanism. Contribution: This research contributes to the body of literature and helps better understand users’ continuance intention in the post-implementation phase of the JTS. It complements the micro-level examinations of continuance intention of using IT, by building on our understanding of the phenomenon at the individual level. Specifically, this study examines the role of technostress where organisations invest in IT to make their users more comfortable with innovative and new technologies like the JTS. Findings: This research develops a theoretical advancement of the expectation-confirmation theory, with implications for IT managers and senior management dealing with IT-related behaviour. All proposed hypotheses were supported. Specifically, the predictors of exhaustion – work overload, work–life balance, and role ambiguity – are significant. The core factors for satisfaction, perceived usefulness, and confirmation, are also found to be significant. Finally, satisfaction and exhaustion significantly influence continuance intention, in both positive and negative ways. Recommendations for Practitioners: This study gives an idea about some of the difficulties that people face when implementing new and innovative IT, particularly in academia in Bangladesh. It offers insights into strategies the management may want to follow when implementing new technology like the JTS. This study suggests strategies to increase satisfaction and reduce technostress among new users to enhance organisational support for change. Recommendation for Researchers: Methodologically, the study provides researchers about the technique that reduces the threat of the common method bias. First, it created a psychological separation between criterion and predictor variables. Second, the threat of common method variance was actively controlled by modelling a latent method factor and by using marker variables that researchers can use in their work. This study complements the micro-level examinations of continuance intention of using IT by building on our understanding of the phenomenon at the individual level. Researchers can extend this model by integrating other theories. Impact on Society: The findings of the study indicate that work overload, work–life conflict, and role ambiguity create tiredness, leading to lower user satisfaction with the system. Perceived usefulness and confirmation have an increasingly similar effect on users’ satisfaction with the system and their subsequent continuance intention. These findings tell university administrators what measures they should take to improve continuance intention of using innovative technology. Future Research: Future studies could conceptualise a five-factor personality model from the personal perspective of users. This model can also be extended by including the dimensions of absorptive capacity, i.e., the dynamic capabilities of users. Absorptive capacity of understanding, assimilating, and applying might influence the user’s perception of usefulness and confirmation of using JTS.

The Mediterranean Institute for Biodiversity and Ecology (IMBE, Aix-Marseille University, Aix-en-Provence, France), in its research group "Macroecology and Biogeography of Global Change (MacroBio)" has a PostDoc position open for applications. The post has a duration of 36 months, the initial contract is made for 18 months, being extended based on an assessment of performance. The position is funded by the European Commission through the FP7 Research Project LUC4C and affiliated to the French National Scientific Research Centre (CNRS).

The main topic is to improve the way LULCC processes are represented in the DGVM LPJmL through enhanced soil and vegetation process representation. Work should improve the model's capacity to project climate-LULCC interactions for the computation of net climate effects, and ecosystem services. One focus is on the representation of diverse agricultural management systems, cropland abandonment/afforestation and forest management, in order to develop ways to account for their effects on biochemical cycles and biophysics.

Post-doctoral scientist position is open for the project "Towards an integrated prediction of Land & Sea Responses to global change in the Mediterranean Basin" (LaSeR-Med), which focusses on integrated socio-ecological modelling. The duration of the contract is initially one year, with a possible extension for a second year, depending on the initial results. The post-doc will be based within the Mediterranean Institute of marine and terrestrial Biodiversity and Ecology (IMBE) in Aix-en-Provence, France. The project is part of the Labex OT-Med (http://www.otmed.fr/).

Applicants should hold a doctoral degree in physics, chemistry, microbiology, geosciences, environmental sciences or a related field of science. They should be familiar with modelling biogeochemical interactions between ecosystems and capable to further develop existing numerical ecosystem models. Programming skills (C) and modelling experience are therefore mandatory. Knowledge of R and of Unix/Linux environment will be an advantage. The candidate should have good written and oral communication skills. For work, good skills in the English language will be essential.

The project:

Terrestrial and marine ecosystems are connected through groundwater, river discharge and nutrient outflows (especially N and P). River catchments in the Mediterranean are N-intensive regions, mostly due to intensive agriculture in the North and to crop N2 fixation or food & feed import in the South. The fraction of nutrient reaching the sea constitutes significant anthropogenic forcing of many marine biological processes. For simulating the dynamics of the first levels of the marine food web (from nutrients to jellyfishes), the ocean biogeochemical model, Eco3M-MED, used and developed by the Mediterranean Institute of Oceanography (MIO) within OT-Med, currently uses N and P measurements at river mouths, e.g. for the Rhône.

In order to estimate the impacts of global change on the functioning of marine ecosystems, the project aims at modeling the dependency of N and P outflows to the Mediterreanean sea toward land management. Land management is modelled as part of the agro-ecosystem model LPJmL (Bondeau et al., 2007), that has been especially adapted to the Mediterranean cropping systems (Fader et al., 2015). Among others, LPJmL simulates the daily carbon and water cycles, and the river discharges to the sea. Following existing approaches in the scientific literature, the post-doc will implement the nutrient N and P transfer in LPJmL, covering the net nutrient inputs to the river catchments by accounting for the processes occurring at the agro-ecosystem level (N2 biological fixation, fertilization, atmospheric deposition) and the net food and feed imports. Since only a minor fraction of the net nutrient inputs from Mediterranean basins reaches the sea, the retention along the nutrient cascade will have to be added to the LPJmL river routing scheme, similarly to the method used by the Riverstrahler model. Once the nutrient transfers have been introduced into LPJmL, simulations will be validated using current climate and land use forcing for comparisons with the existing observations from river outlets. Finally, future conditions will be assessed by using the model with scenarios of changing regional climate and land use / land management.

Your application:

Applications should contain a suitable motivation letter describing your anticipated role in the project, a CV, a list of scientific publications and the names of at least two scientists that can be contacted for references. They must be sent to Ms. Gabriela Boéri (gabriela.boeri@imbe.fr). Please prepare your application as a single file in pdf-format.

Questions about the project or the position can be directed to Dr. Alberte Bondeau (alberte.bondeau@imbe.fr).

A new EU BON acknowledging data article provides a virtual species set as a valuable tool in biodiversity monitoring. 

Abstract

Predicting species potential and future distribution has become a relevant tool in biodiversity monitoring and conservation. In this data article we present the suitability map of a virtual species generated based on two bioclimatic variables, and a dataset containing more than 700,000 random observations at the extent of Europe. The dataset includes spatial attributes such as: distance to roads, protected areas, country codes, and the habitat suitability of two spatially clustered species (grassland and forest species) and a wide-spread species.

A new editorial, published in the Journal of Apllied Ecology looks at modelling and monitoring as methods for adaptive biodiversity management in the 21st century.

Abstract: 

With increasing threats on biodiversity, informed conservation decisions need to be based on currently observed and future predicted trends of biodiversity (Pereira, Navarro & Martins 2012; Guisan et al. 2013). In this regard, two essential components supporting informed biodiversity conservation decisions are good monitoring data to assess recent and ongoing trends (Collen et al. 2013; Pereira et al. 2013) and robust models to anticipate possible future trends (Pereira et al. 2010a; Akc
akaya et al. 2016). Models benefit from robust monitoring data sets, that is repeated observations of biodiversity, as they need data to be fitted or validated, but models can also help assess data representativeness (e.g. by highlighting any bias), support proper data collection (e.g. covering the relevant gradients) or be used to make more effective use of biodiversity observations (Guisan et al. 2006, 2013; Ferrier 2011).

Three-dimensional electron diffraction (3D-ED) is a powerful technique for crystallographic characterization of nanometre-sized crystals that are too small for X-ray diffraction. For accurate crystal structure refinement, however, it is important that the Bragg diffracted intensities are treated dynamically. Bloch wave simulations are often used in 3D-ED, but can be computationally expensive for large unit cell crystals due to the large number of diffracted beams. Proposed here is an alternative method, the `scattering cluster algorithm' (SCA), that replaces the eigen-decomposition operation in Bloch waves with a simpler matrix multiplication. The underlying principle of SCA is that the intensity of a given Bragg reflection is largely determined by intensity transfer (i.e. `scattering') from a cluster of neighbouring diffracted beams. However, the penalty for using matrix multiplication is that the sample must be divided into a series of thin slices and the diffracted beams calculated iteratively, similar to the multislice approach. Therefore, SCA is more suitable for thin specimens. The accuracy and speed of SCA are demonstrated on tri-iso­propyl silane (TIPS) pentacene and rubrene, two exemplar organic materials with large unit cells.

The strong interaction of high-energy electrons with a crystal results in both dynamical elastic scattering and inelastic events, particularly phonon and plasmon excitation, which have relatively large cross sections. For accurate crystal structure refinement it is therefore important to uncover the impact of inelastic scattering on the Bragg beam intensities. Here a combined Bloch wave–Monte Carlo method is used to simulate phonon and plasmon scattering in crystals. The simulated thermal and plasmon diffuse scattering are consistent with experimental results. The simulations also confirm the empirical observation of a weaker unscattered beam intensity with increasing energy loss in the low-loss regime, while the Bragg-diffracted beam intensities do not change significantly. The beam intensities include the diffuse scattered background and have been normalized to adjust for the inelastic scattering cross section. It is speculated that the random azimuthal scattering angle during inelastic events transfers part of the unscattered beam intensity to the inner Bragg reflections. Inelastic scattering should not significantly influence crystal structure refinement, provided there are no artefacts from any background subtraction, since the relative intensity of the diffracted beams (which includes the diffuse scattering) remains approximately constant in the low energy loss regime.

Maximizing the performance of crystal monochromators is a key aspect in the design of beamline optics for diffraction-limited synchrotron sources. Temperature and deformation of cryo-cooled crystals, illuminated by high-power beams of X-rays, can be estimated with a purely analytical model. The analysis is based on the thermal properties of cryo-cooled silicon crystals and the cooling geometry. Deformation amplitudes can be obtained, quickly and reliably. In this article the concept of threshold power conditions is introduced and defined analytically. The contribution of parameters such as liquid-nitro­gen cooling efficiency, thermal contact conductance and interface contact area of the crystal with the cooling base is evaluated. The optimal crystal illumination and the base temperature are inferred, which help minimize the optics deformation. The model has been examined using finite-element analysis studies performed for several beamlines of the Diamond-II upgrade.

Lecithin:cholesterol-acyl-transferase (LCAT) plays a major role in cholesterol metabolism as it is the only extracellular enzyme able to esterify cholesterol. LCAT activity is required for lipoprotein remodelling and, most specifically, for the growth and maturation of HDLs. In fact, genetic alterations affecting LCAT func- tionality may cause a severe reduction in plasma levels of HDL-cholesterol with important clinical consequences. Although several hypotheses were formulated, the exact molecular recognition mechanism between LCAT and HDLs is still unknown. We employed a combination of structural bioinformatics procedures to deepen the insights into the HDL-LCAT interplay that promotes LCAT activation and cholesterol esterification. We have generated a data-driven model of reconstituted HDL (rHDL) and studied the dynamics of an assembled rHDL::LCAT supramolecular complex, pinpointing the conformational changes originating from the interaction between LCAT and apolipoprotein A-I (apoA-I) that are necessary for LCAT activation. Specifically, we propose a mechanism in which the anchoring of LCAT lid to apoA-I helices allows the formation of a hydrophobic hood that expands LCAT active site and shields it from the solvent, allowing the enzyme to process large hydrophobic substrates.

Hi all,

I'm trying to model the clock of a clock doubler. The doubler consists of a delay cell and an XOR gate, which generates a pulse on both the rising and falling edge of the input clock. I've created a simple module to evaluate this. In this case, DEL1 and XOR2 are standard library cells. There is a don_touch constraint on both library cells as well as on clk_d.

module top (
input wire clk,
output reg Q);

//Doubler
wire clk_d;
wire clk_2x;
DEL1 u_delay (.I(clk),.Z(clk_d));
XOR2 u_xor (.A1(clk),.A2(clk_d),.Z(clk_2x));

//FF for connecting the clock to some leaf:
always @(posedge clk_2x) Q<=~Q;

endmodule

My SDC looks like this:

create_clock [get_ports {clk}] -name clk_i -period 100
set_clock_latency -rise 0.1 [get_pins u_xor/Z]
set_clock_latency -fall 0.4 [get_pins u_xor/Z]
create_generated_clock -name clk_2x -edges {1 1 2 2 3} -source clk [get_pins u_xor/Z]

The generated clock is correctly generated but the pulse width is zero. I would be expecting that the pulse width is the difference between fall and rise latency but is not applied:

report_clocks:

report_clocks -generated:

clk_2x is disconnected from the FF after syn_generic. What can I do to model some minimum pulse width? Will innovus later on model this correctly with the delay of DEL1?
