    This paper presents a study of new product development (NPD) processes in two large Australian organisations (National Foods and Lion Nathan) involved in the production of fast moving consumer goods. The research utilises the Australian Business Excellence Framework as a research lens for exploring NPD processes with a focus on the role of sales and operations management. A case study approach used data collected from employees in the two organisations who were involved the NPD process. The results showed a number of significant differences between the two organisations in the conduct and the effectiveness of their NPD processes. Although both organisations employed a formal Stage-Gate process, Lion Nathan did this more successfully than National Foods, perhaps because of Lion Nathan’s greater experience with using stage-gate methodology. This study highlights the importance of the role of sales and operation planning, especially in relation to collaborative demand forecasting. The importance of the leadership role was also evident particularly in relation to ensuring measurement, review, and improvement of NPD processes

    During July and August 1977, in an Amazonian rain forest area of about 1 km2 near the settlement of Araracuara, Caqueta, Colombia, Sur America, a survey of the phlebotomine sandfly fauna was carried out, using several methods of collection (Shannon traps, light traps, human bait catches and manual catches of resting sandflies with aspirators). Thirty five species of Lutzomyia were encountered (2.145 and 2.903), of which 6 species were new records for Colombia and one a new species which is described from 23 male specimens as Lutzomyia araracuarensis sp. nov. and is allocated to the Gasparviannai group. The female of Lutzomyia wagleyi (longispina group) is described for the first time. Males and females of two apparently unknown species are described and provisionally designated as Lutzomyia sp. No. 1, Araracuara, and Lu. sp.No. 2, Araracuara: Lu. sp. No. 1 is allocated to the subgenus Trichophoramyia and Lu. sp. No. 2 to the oswaldoi group. Twenty four female sandflies (5 species) were infested with mites which were identified variously to the family or generic level.Durante julio y agosto de 1977. en un área de cerca de 1 km2 de bosque lluvioso tropical de la Amazonía, cerca de la localidad de Araracuara.

    We report on multi-frequency, wideband radio observations of the Galactic Center magnetar (SGR 1745-2900) with the Green Bank Telescope for \sim100 days immediately following its initial X-ray outburst in April 2013. We made multiple simultaneous observations at 1.5, 2.0, and 8.9 GHz, allowing us to examine the magnetar's flux evolution, radio spectrum, and interstellar medium parameters (such as the dispersion measure (DM), the scattering timescale and its index). During two epochs, we have simultaneous observations from the Chandra X-ray Observatory, which permitted the absolute alignment of the radio and X-ray profiles. As with the two other radio magnetars with published alignments, the radio profile lies within the broad peak of the X-ray profile, preceding the X-ray profile maximum by \sim0.2 rotations. We also find that the radio spectral index γ\gamma is significantly negative between \sim2 and 9 GHz; during the final \sim30 days of our observations γ1.4\gamma \sim -1.4, which is typical of canonical pulsars. The radio flux has not decreased during this outburst, whereas the long-term trends in the other radio magnetars show concomitant fading of the radio and X-ray fluxes. Finally, our wideband measurements of the DMs taken in adjacent frequency bands in tandem are stochastically inconsistent with one another. Based on recent theoretical predictions, we consider the possibility that the dispersion measure is frequency-dependent. Despite having several properties in common with the other radio magnetars, such as LX,qui/Lrot1L_{\textrm{X,qui}}/L_{\textrm{rot}} \lesssim 1, an increase in the radio flux during the X-ray flux decay has not been observed thus far in other systems.Comment: 15 pages, 9 figures, 3 tables; accepted to Ap

    A 42.3-43.6 GHz spectral survey of Orion BN/KL: First detection of the v=0 J=1-0 line from the isotopologues 29SiO and 30SiO

    We have surveyed molecular line emission from Orion BN/KL from 42.3 to 43.6 GHz with the Green Bank Telescope. Sixty-seven lines were identified and ascribed to 13 different molecular species. The spectrum at 7 mm is dominated by SiO, SO2, CH3OCH3, and C2H5CN. Five transitions have been detected from the SiO isotopologues 28SiO, 29SiO, and 30SiO. We report here for the first time the spectra of the 29SiO and 30SiO v=0 J=1-0 emission in Orion BN/KL, and we show that they have double-peaked profiles with velocity extents similar to the main isotopologue. The main motivation for the survey was the search of high-velocity (100-1000 km/s) outflows in the BN/KL region as traced by SiO Doppler components. Some of the unidentified lines in principle could be high-velocity SiO features, but without imaging data their location cannot be established. Wings of emission are present in the v=0 28SiO, 29SiO and 30SiO profiles, and we suggest that the v=0 emission from the three isotopologues might trace a moderately high-velocity (~30-50 km/s) component of the flows around the high-mass protostar Source I in the Orion BN/KL region. We also confirm the 7 mm detection of a complex oxygen-bearing species, acetone (CH3COCH3), which has been recently observed towards the hot core at 3 mm, and we have found further indications of the presence of long cyanopolyynes (HC5N and HC7N) in the quiescent cold gas of the extended ridge.Comment: 27 pages, 3 figures, accepted by Ap

    A call for a wider perspective on sustainable forestry: introduction to the Special Issue on The Social Impacts of Logging

    Get PDF
    Global demand for timber is projected to grow and much of this timber will continue to be sourced from natural forests. As these forests, particularly in the tropics, tend to be inhabited by the world's most marginalized communities, the social impacts of logging require more attention within policy, practice and research. This Introduction to the Special Issue of International Forestry Review on The Social Impacts of Logging compiles evidence that the overwhelmingly negative social impacts of logging are systemic. As logging companies fail to fulfill their social obligations, and elite capture is common, the extent to which local communities benefit from logging operations is minimal, while long-term, harmful effects on livelihoods, social fabric and safety are severe. Logging operations reinforce and often exacerbate pre-existing inequities, particularly for women and Indigenous people. Weak governance, a lack of transparency and poor participation procedures partially explain this unfavourable situation. However, logging will only achieve better social outcomes if underlying power-imbalances are tackled.Horizon 2020(H2020)748242Global Challenges (FSW

    A strongly magnetized pulsar within grasp of the Milky Way's supermassive black hole

    Full text link
    The center of our Galaxy hosts a supermassive black hole, Sagittarius (Sgr) A*. Young, massive stars within 0.5 pc of SgrA* are evidence of an episode of intense star formation near the black hole a few Myr ago, which might have left behind a young neutron star traveling deep into SgrA*'s gravitational potential. On 2013 April 25, a short X-ray burst was observed from the direction of the Galactic center. Thanks to a series of observations with the Chandra and the Swift satellites, we pinpoint the associated magnetar at an angular distance of 2.4+/-0.3 arcsec from SgrA*, and refine the source spin period and its derivative (P=3.7635537(2) s and \dot{P} = 6.61(4)x10^{-12} s/s), confirmed by quasi simultaneous radio observations performed with the Green Bank (GBT) and Parkes antennas, which also constrain a Dispersion Measure of DM=1750+/-50 pc cm^{-3}, the highest ever observed for a radio pulsar. We have found that this X-ray source is a young magnetar at ~0.07-2 pc from SgrA*. Simulations of its possible motion around SgrA* show that it is likely (~90% probability) in a bound orbit around the black hole. The radiation front produced by the past activity from the magnetar passing through the molecular clouds surrounding the Galactic center region, might be responsible for a large fraction of the light echoes observed in the Fe fluorescence features.Comment: ApJ Letters in pres

    Parametric Oscillation of a Moving Mirror Driven by Radiation Pressure in a Superconducting Fabry-Perot Resonating System

    Full text link
    A moving pellicle superconducting mirror, which is driven by radiation pressure on its one side, and by the Coulomb force on its other side, can become a parametric oscillator that can generate microwaves when placed within a high-Q superconducting Fabry-Perot resonator system. A paraxial-wave analysis shows that the fundamental resonator eigenmode needed for parametric oscillation is the TM011 mode. A double Fabry-Perot structure is introduced to resonate the pump and the idler modes, but to reject the parasitic anti-Stokes mode. The threshold for oscillation is estimated based on the radiation-pressure coupling of the pump to the signal and idler modes, and indicates that the experiment is feasible to perform.Comment: 30 pages, 6 figures, part of proceedings of FQMT 2011 conference in Prague, Czech Republi
