Critical Success Factors for SMEs: An Empirical Study in the UK Chemical Distribution Industry
Authors: Lampadarios Evripidis 
Published: June 2016

<p>The UK chemical distribution industry, which is a well-established, fragmented, subject to strong consolidation, significant part of the chemical industry and a major contributor to the UK economy and employment, remains largely unexplored, with no research in the factors contributing to SMEs success. This is the first study to identify the factors critical to small business success and provide an integrative perspective in the specific industry. The research is based on the opinions of owners and very senior managers (Managing Directors, Directors, CEOs and CFOs), an approach extensively used by other researchers. A total of 180 SMEs fulfilling the criteria of this study are identified with 118 owners/managers participating, generating a very satisfactory response rate of 65.5%. Regulatory Compliance, Entrepreneurial Orientation, Customer Relations Management, Market and Product development, Prior Work Experience and Management Skills, Human Capital, Economic Environment and Strategic Planning are established as critical success factors (CSFs). Findings suggest that success is a multidimensional phenomenon where both firm-internal and firm-external factors need to be optimal simultaneously; satisfying one or two factors does not necessarily guarantee success. Strong interrelationships are also revealed amongst the critical and non-critical success factors. The paper contributes towards the integration of SMEs success factors theories and provides guidelines to various stakeholders and policy-makers to improve strategy formulation and decision-making process in supporting chemical distribution SMEs.</p>

Este trabalho teve por objetivos avaliar o efeito de dosagens de fósforo no crescimento de mudas de palmiteiro, bem como determinar o teor de macro e micronutrientes do sistema radicial e aéreo dessa planta. O ensaio foi conduzido em casa de vegetação. Os tratamentos foram quantitativos e eqüidistantes, constituídos por: T1-testemunha solo sem adição de fósforo (P); T2-90 mg.kg-1; T3-180 mg; T4-270 mg.dm-3; T5-360mg dm-3; T6-450 mg.dm-3; T7-540 mg.dm-3; T8-630 mg.dm-3; de P respectivamente. Decorridos 12 meses da semeadura, foram avaliadas variáveis: altura e biomassa aérea, radicial e total, pela análise nutricional dos tecidos. Os resultados indicam que houve crescimento de plantas jovens de palmiteiro para todos os parâmetros avaliados. O crescimento em altura e o aumento da biomassa aérea das plantas jovens de palmito foram até a dosagem de 540 mg.dm-3 de fósforo. A resposta foi positiva para o desenvolvimento da biomassa radical até a dosagem de 450 mg.dm-3, sendo que o desenvolvimento de biomassa total foi alcançado com a dosagem de 540 mg.dm-3 de fósforo. Para os teores de macro na biomassa aérea obteve-se a seguinte seqüência, respectivamente: N > Ca > K > Mg > P>S; e micronutrientes Fe > Mn > Zn > B > Cu; e para radical: N > Ca > Mg > S > K > P; Fe > Mn > Zn > B > Cu, sendo que os teores de P não alteraram os teores de nutrientes na planta.

O Inventário Florístico-Florestal do Estado de Santa Catarina tem por objetivo inventariar e analisar a composição florística e a estrutura horizontal e vertical dos remanescentes florestais do Estado, registrar a diversidade arbórea das florestas e coletar dados sobre as espécies vegetais ameaçadas de extinção. A cobertura florestal de seu território de 95.443 km² é inferior a 30%, porém, extremamente reduzida e fragmentada na sua região oeste do eEstado. Nesse estudo-piloto, foram implantadas 74 unidades amostrais de 2000 m² cada, distribuídas aleatoriamente numa área de 41.380 km² nos domínios da Floresta Ombrófila Mista. Além da análise usual da estrutura horizontal e vertical, os dados de densidade foram utilizados para a construção de uma matriz de densidades (espécie/parcela) que foi submetida à Análise de Correspondência Corrigida (ACC). Os resultados do levantamento indicam Myrtaceae, Lauraceae e Fabaceae como famílias mais abundantes, seguidas de Asteraceae e Solanaceae. O levantamento registrou 133 espécies com DAP ≥ 10cm, 101 espécies com DAP <10cm ≥1cm e 105 espécies com DAP menor que 1cm. Existe um número restrito de espécies muito freqüentes, enquanto 120 espécies ocorrem em menos de dez das 74 unidades amostrais e 46 espécies são presentes em apenas uma unidade. Os resultados da Análise de Correspondência mostram dois conjuntos de unidades amostrais, um caracterizado por espécies da Floresta Ombrófila Mista, outro com forte influência de espécies da Floresta Estacional Decidual. Este agrupamento se fez presente com nitidez dentro da grande região geográfica originalmente identificada como região da Floresta Ombrófila Mista e dos Campos Naturais. Os dois grupos mostram-se distintos quanto à sua estrutura e flora. Este resultado propõe a necessidade de novos levantamentos para verificar se realmente existe uma diferenciação florística ao longo dessa linha divisória, preliminarmente estabelecida. As próximas fases do Inventário Florestal de Santa Catarina poderão contribuir para verificação dessa hipótese.

A hibridação de espécies de eucalipto possibilita a obtenção de híbridos mais produtivos e com alta eficiência de absorção e/ou utilização de nutrientes, dependendo das espécies combinadas. Neste contexto, o presente trabalho, conduzido na região do Vale do Jequitinhonha, Minas Gerais, teve por objetivos: determinar a produtividade, o conteúdo e a eficiência de utilização de N, P, K, Ca e Mg de híbridos interespecíficos de Eucalyptus spp. Para tanto, mediu-se o diâmetro à altura do peito (DAP) de todas as árvores presentes em cada parcela, e abateram-se três árvores com diâmetro correspondente ao da árvore média. Procedeu-se à cubagem das árvores pelo método de Smallian, utilizando a altura, o diâmetro e a espessura de casca na base e a 25, 50, 75 e 100 % da altura comercial. O peso de material fresco do lenho, da casca, das folhas e dos galhos foi determinado no campo, e desses componentes se coletaram amostras para determinação do peso da matéria seca. As amostras do tronco consistiram de discos coletados, com casca, na base e a 25, 50, 75 e 100% da altura comercial. As amostras de tecido vegetal foram analisadas para: N, P, K, Ca e Mg. Os resultados obtidos não indicaram diferenças significativas para a produção de biomassa de copa entre os híbridos de eucalipto em conseqüência de apresentarem mesma idade. Entretanto, a produção de biomassa de tronco apresentou diferenças significativas sendo os híbridos de Eucalyptus urophylla S. T. Blake proveniente de polinização natural mais produtivo em 50 e 69% em comparação aos híbridos de Eucalyptus urophylla W. Hill. Ex Maiden com Eucalyptus grandis Dehnh.e de Eucalyptus urophylla com descendentes do cruzamento de Eucalyptus camaldulensis com Eucalyptus grandis respectivamente. Além disso, aqueles híbridos foram os que alocaram maior quantidade de biomassa no tronco (92,3%) em relação à copa (7,7%), e ainda foram os mais eficientes na absorção e utilização de N, P, K, Ca e Mg. Concluiu-se que: 1) híbridos de Eucalyptus urophylla provenientes de polinização natural ou controlada não apresentam diferença na produção de biomassa de copa quando avaliados numa mesma idade; 2) a polinização controlada de Eucalyptus urophylla com Eucalyptus grandis e com descendentes do cruzamento de Eucalyptus camaldulensis com Eucalyptus grandis reduz a produção de biomassa de tronco; 3) híbridos de Eucalyptus urophylla provenientes de polinização natural são mais produtivos e mais eficientes na absorção e utilização de N, P, K, Ca e Mg e 4) híbridos de Eucalyptus urophylla provenientes de descendentes do cruzamento de Eucalyptus camaldulensis com Eucalyptus grandis são menos produtivos e menos eficientes na absorção e utilização de N, P, K, Ca e Mg.

La participation du client au sein d’un environnement commercial : exploration des dispositifs et de l’initiative client dans un lieu attachant
Authors: Bonnemaizon Audrey , Debenedetti Alain , Mérigot Philippe 
Published: June 2016

La littérature limite généralement la participation du consommateur dans les lieux commerciaux aux dispositifs technologiques encadrés que propose la grande distribution, négligeant ainsi les autres éléments constitutifs du lieu (spatiaux, sociaux, symboliques) et la potentialité d’une participation initiée par le client. Cette recherche ethnographique réalisée dans un restaurant parisien dévoile trois formes de participation qui contribuent au positionnement du lieu et qui impliquent des degrés de matérialité et d’initiative variés : la « participation-appropriation », la « participation-contribution », et la « participation-transmission ». Elle contribue à la compréhension de la participation du client, et plus spécifiquement au sein de lieux commerciaux suscitant des liens affectifs forts.
Forcing of the overturning circulation across a circumpolar channel by internal wave breaking

Published: June 2016

AbstractThe hypothesis that the impingement of mesoscale eddy flows on small‐scale topography regulates diapycnal mixing and meridional overturning across the deep Southern Ocean is assessed in an idealized model. The model simulates an eddying circumpolar current coupled to a double‐celled meridional overturning with properties broadly resembling those of the Southern Ocean circulation and represents lee wave‐induced diapycnal mixing using an online formulation grounded on wave radiation theory. The diapycnal mixing generated by the simulated eddy field is found to play a major role in sustaining the lower overturning cell in the model, and to underpin a significant sensitivity of this cell to wind forcing. The vertical structure of lower overturning is set by mesoscale eddies, which propagate the effects of near‐bottom diapycnal mixing by displacing isopycnals vertically.
Long‐term assessment of Aqua MODIS radiance observation using comparisons with AIRS and IASI

AbstractThis paper presents a detailed comparison between Atmospheric Infrared Sounder (AIRS) and Moderate Resolution Imaging Spectroradiometer (MODIS) measurements over the period 2003–2013 and also between MODIS and Infrared Atmospheric Sounding Interferometer (IASI) for the years 2007–2014. For this study AIRS and IASI high spectral resolution data are degraded to MODIS broadband spectral resolution and MODIS fields of view are averaged within the AIRS and IASI footprints. Using spatially uniform scenes, the brightness temperature differences (ΔBT) between MODIS and AIRS are analyzed as a function of scene temperature, scan angle, and solar zenith angle. In general, the measurements of the two sensors are in good agreement (ΔBT less than ±0.2 K) with little or no dependence on the scene temperature. A small dependence is found for the scan angle, where ΔBT varies off nadir up to about ±0.4 K; dependence on the solar zenith angle is also observed, with ΔBT varying up to ±0.5 K. Finally, the variation of ΔBT over time is stable with BT trending less than 0.02 K/yr, with exception of ΔBT for MODIS bands 33 and 35 in the 2011–2013 timeframe. This behavior, which is also identified in MODIS/IASI comparisons, correlates to adjustments in that timeframe of the MODIS nonlinear calibration coefficients.

AbstractAccurate information about aerosol vertical distribution is needed to reduce uncertainties in aerosol radiative forcing and its effect on atmospheric dynamics. The present study deals with synergistic analyses of aerosol vertical distribution and aerosol optical depth (AOD) with meteorological variables using multisatellite and ground‐based remote sensors over Kanpur in central Indo‐Gangetic Plain (IGP). Micro‐Pulse Lidar Network‐derived aerosol vertical extinction (σ) profiles are analyzed to quantify the interannual and daytime variations during monsoon onset period (May–June) for 2009–2011. The mean aerosol profile is broadly categorized into two layers viz., a surface layer (SL) extending up to 1.5 km (where σ decreased exponentially with height) and an elevated aerosol layer (EAL) extending between 1.5 and 5.5 km. The increase in total columnar aerosol loading is associated with relatively higher increase in contribution from EAL loading than that from SL. The mean contributions of EALs are about 60%, 51%, and 50% to total columnar AOD during 2009, 2010, and 2011, respectively. We observe distinct parabolic EALs during early morning and late evening but uniformly mixed EALs during midday. The interannual and daytime variations of EALs are mainly influenced by long‐range transport and convective capacity of the local emissions, respectively. Radiative flux analysis shows that clear‐sky incoming solar radiation at surface is reduced with increase in AOD, which indicates significant cooling at surface. Collocated analysis of atmospheric temperature and aerosol loading reveals that increase in AOD not only resulted in surface dimming but also reduced the temperature (∼2–3°C) of lower troposphere (below 3 km altitude). Radiative transfer simulations indicate that the reduction of incoming solar radiation at surface is mainly due to increased absorption by EALs (with increase in total AOD). The observed cooling in lower troposphere in high aerosol loading scenario could be understood as a dynamical feedback of EAL‐induced stratification of lower troposphere. Further, the observed radiative effect of EALs increases the stability of the lower troposphere, which could modulate the large‐scale atmospheric dynamics during monsoon onset period. These findings encourage follow‐up studies on the implication of EALs to the Indian summer monsoon dynamics using numerical models.
Microfluidic observation of the onset of reactive‐infitration instability in an analog fracture

Published: June 2016

AbstractReactive‐infiltration instability plays an important role in many geophysical problems yet theoretical models have rarely been validated experimentally. We study the dissolution of an analog fracture in a simple microfluidic setup, with a gypsum block inserted in between two polycarbonate plates. By changing the flow rate and the distance between the plates, we are able to scan a relatively wide range of Péclet and Damkhöhler numbers, characterizing the relative magnitude of advection, diffusion, and reaction in the system. We quantify the characteristic initial wavelengths of the perturbed fronts during the onset of instability. The results agree well with theoretical predictions based on linear stability analysis, thus experimentally validating current reactive‐infiltration instability theory and opening new opportunities for experimental assessment of mineral reactivity.

AbstractMittels Phagen‐Display wurden Peptide identifiziert, die materialspezifische Adsorption zeigen und effektiv zwischen Cellulose als Hauptbestandteil von Papier und dem Toner eines mit einem handelsüblichen Laserdrucker gedruckten Musters unterscheiden können. Diese genetisch selektierten 12mer‐Peptide können selektiv entweder nicht bedruckte Cellulose oder gedruckte Tonerstrukturen beschichten. Weiterhin wird eine chemische Ligation mit Triazolindion genutzt, um z. B. Farbstoffe und funktionale Peptide selektiv auf einer Oberflächenbeschichtung zu befestigen. Diese Methode bietet einen einfachen Zugang zur Funktionalisierung von Mustern auf papierbasierten Materialien, wodurch neue Wege zur Realisierung kostengünstiger diagnostischer oder biomedizinischer Geräte aufgezeigt werden können.

Published: June 2016

AbstractThis study presents a full operation and optimization of a mixing unit; an innovative approach is developed to address the behaviour of gas–liquid mixing by using electrical resistance tomography. The validity of the method is investigated by developing the tomographic images using different numbers of baffles in a mixing unit. This technique provided clear visual evidence of better mixing that took place inside the gas−liquid system and the effect of a different number of baffles on mixing characteristics. For optimum gas flow rate (m3/s) and power input (kW), the oxygen absorption rate in water was measured. Dynamic gassing‐out method was applied for five different gas flow rates and four different power inputs to find out mass transfer coefficient (KLa). The rest of the experiments with one up to four baffles were carried out at these optimum values of power input (2.0 kW) and gas flow rate (8.5 × 10−4 m3/s). The experimental results and tomography visualizations showed that the gas−liquid mixing with standard baffling provided near the optimal process performance and good mechanical stability, as higher mass transfer rates were obtained using a greater number of baffles. The addition of single baffle had a striking effect on mixing efficiency, and additions of further baffles significantly decrease mixing time. The energy required for complete mixing was remarkably reduced in the case of four baffles as compared with without any baffle. The process economics study showed that the increased cost of baffle installation accounts for less cost of energy input for agitation. The process economics have also revealed that the optimum numbers of baffles are four in the present mixing unit, and the use of an optimum number of baffles reduced the energy input cost by 54%. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.

Published: June 2016

ABSTRACTHighly ordered honeycomb‐patterned polystyrene surfaces are efficiently prepared by static breath figure method. The structured arrays can be obtained by casting a dilute solution polymer on glass substrates under various conditions. Tetrahydrofuran and chloroform are used as solvent to form cavities of several micrometers. The analysis of the surfaces indicates nonlinear relation between concentration and pore size in this system. Voronoi tessellations of the polystyrene surfaces at different relative humidity (RH) are achieved, and each conformational entropy determined. Optimum parameters of concentration and RH are obtained for both solvents. Analysis of hole size distribution and conformational entropy demonstrates the high order of the films obtained. This is a promising method for the fabrication of homogeneous and highly porous films from polystyrene. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44004.
Determination of reactivity ratios for the copolymerization of poly(acrylic acid‐co‐itaconic acid)

Published: June 2016

ABSTRACTMonomer reactivity ratios are important parameters used in copolymerization kinetics to predict the rate of polymerization, copolymer composition and monomer sequence length, and by extension, molecular weight and distribution of the final product. Batch aqueous solution copolymerizations of acrylic acid (AA) and itaconic acid (IA) are performed at various feed compositions. Polymerizations are categorized into low (<11 wt %) conversion and higher (< 30 wt %) conversion data sets for analysis. Due to the limited solubility of IA in the reaction mixture, the feed composition of IA in all polymerizations is constrained to lower than 25 mol %. Conversion is determined by gravimetric methods, and copolymer composition via 1H‐NMR spectroscopy. All data are analyzed using the error‐in‐variables model (EVM) method. Two analyses are used, one with the EVM approach and another with a novel Direct Numerical Integration (DNI) coupled with the EVM method. The DNI/EVM approach yields values of rAA = 0.36 and rIA = 1.62 for the reactivity ratios. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44014.
