From IRIOP to the JOB Annual Review: The past and future of a venerable outlet
Authors: Harvey Paul , Dasborough Marie 
Published: February 2017

SummaryAs incoming co‐editors, we introduce the 2017 International Review of Industrial and Organizational Psychology (IRIOP) Annual Review Issue. We begin this editorial with a brief history of IRIOP, from its creation as a book series in 1986 to the present issue—its fifth as an annual Journal of Organizational Behavior publication. We also summarize several changes we will be implementing, including expanded page limits for submissions and a name change. Most importantly, we then introduce the six manuscripts that appear in this issue. These papers, selected by former editors Gerard Hodgkinson and Kevin Ford, carry on the tradition of high‐quality, impactful reviews that IRIOP has published for the past 30 years.

Objectives/HypothesisLocal anesthetic with epinephrine is commonly injected into the nasal mucosa during functional endoscopic sinus surgery (FESS). Systemic absorption of epinephrine following local injection may occur, resulting in a mild sympathetic response. This study seeks to determine whether an exaggerated sympathetic response to epinephrine is demonstrated in patients undergoing FESS treated preoperatively with established pharmacologic beta (β) adrenoceptor blockade.Study DesignA retrospective analysis of adult patients undergoing FESS at a tertiary care university hospital.MethodsThe primary outcome was the occurrence of an exaggerated hypertensive response within the first hour of surgical time defined by a relative increase (>20%) in the first measured intraoperative systolic blood pressure (SBP) prior to induction of anesthesia, or a single SBP value above 200 mm Hg. A mixed effects logistic regression model was developed to identify independent predictors of an exaggerated hypertensive response and describe the variance in the outcome attributable to the surgeon and anesthesiologist.ResultsThere were 2,051 patients identified. Independent predictors of an exaggerated intraoperative hypertensive event included: preoperative β‐blocker use (adjusted odds ratio [AOR]: 3.33), female gender (AOR: 1.92), body mass index (AOR: 1.03), lower baseline SBP (AOR: 0.93), and advanced age (AOR: 1.03). The C statistic for the model was 0.8881.ConclusionsPreoperative β‐blocker use is an independent predictor of an exaggerated hypertensive response within the first hour of operative time. An exaggerated hypertensive effect should be anticipated in patients presenting for FESS with established pharmacologic β‐blockade, and caution should be applied to use of epinephrine‐containing solutions.Level of Evidence4.

Soil Reserves of Potassium: Release and Availability to Lolium perenne in Relation to Clay Minerals in Six Cropland Soils from Eastern China
Authors: Li Ting , Wang Huoyan , Chen Xiaoqin , Zhou Jianmin 
Published: February 2017

AbstractAn 8‐month greenhouse experiment with ryegrass (Lolium perenne L.) examined the relationship between the dynamics of potassium (K) reserves in soil and changes in clay minerals, using X‐ray diffraction. The capacity of soil to release K was consistent with its ability to supply it and was the highest in the soil samples collected from Laiyang (H1T2a), Harbin (H1T1) and Beibei (H2T4), followed by the sample from Jiangyan (H1T2b), and the lowest in the samples from Gao'an (H2T3a) and Wangcheng (H2T3b). Removal of soil K decreases the intensity of reflections for illite and increases that for interstratified clay minerals. The centre of gravity values of the clay fractions was significantly negatively correlated to the depletion of soil K reserves, as ascertained through chemical extraction or through plant action. The quantitative regression equations between the centre of gravity values and the dynamics of soil reserves of K can be used for predicting the release and plant availability of K even without growing a crop.

AbstractDespite evidence of internal waves in the NW Iberian upwelling region, their action and role on nutrient supply dynamics and phytoplankton community structure remain unexplored. A multidisciplinary approach, combining analysis of Synthetic Aperture Radar (SAR) images acquired during the summer months of 2008–2011, together with high‐frequency samplings carried out in the Ría de Vigo in August 2013 during spring (CHAOS1) and neap tides (CHAOS2), was used to characterize: (1) the internal wave activity, (2) its influence on mixing and nutrient supply, and (3) its role on phytoplankton community. SAR images revealed that internal waves were more energetic during spring tides. Turbulent mixing was higher during CHAOS1‐springs (Kz =1.3 [1.0–2.0, 95% confidence interval] × 10−3 m2 s−1) compared to CHAOS2‐neaps (Kz = 0.7 [0.5–1.0] × 10−3 m2 s−1), and as a result nitrate diffusive fluxes were approximately fourfold higher (35 [17–73] mmol m−2 d−1) during CHAOS1‐springs. The sampling covered a transition from relaxation‐stratification (CHAOS1‐springs) to intensifying upwelling (CHAOS2‐neaps) conditions, resulting in nitrate supply (including both diffusive and advective fluxes) being about 50% higher during CHAOS2‐neaps. The phytoplankton community, which was overwhelmingly dominated by diatoms in both cruises, exhibited a shift in species composition, with an increase in the abundance of large Chaetoceros spp. during CHAOS2‐neaps. About 50% of the primary production in the ecosystem during periods of upwelling relaxation‐stratification could be sustained by enhanced nitrate diffusive fluxes during spring tides. Therefore, even in coastal upwelling regions, turbulent mixing driven by internal waves could play an important role in controlling phytoplankton productivity and community structure.

AbstractPhytoplankton are critical component of the food web in most large rivers and estuaries, and thus identifying dominant controls on phytoplankton abundance and species composition is important to scientists, managers, and policymakers. Recent studies from a variety of systems indicate that ammonium (
) in treated wastewater effluent decreases primary production and alters phytoplankton species composition. However, these findings are based mainly on laboratory and enclosure studies, which may not adequately represent natural systems. To test effects of effluent high in ammonium on phytoplankton at the ecosystem scale, we conducted whole‐river–scale experiments by halting discharges to the Sacramento River from the regional wastewater treatment plant (WWTP), and used a Lagrangian approach to compare changes in phytoplankton abundance and species composition in the presence (+EFF) and absence (−EFF) of effluent. Over 5 d of downstream travel from 20 km above to 50 km below the WWTP, chlorophyll concentrations declined from 15–25 to ∼2.5 μg L−1, irrespective of effluent addition. Benthic diatoms were dominant in most samples. We found no significant difference in phytoplankton abundance or species composition between +EFF and −EFF conditions. Moreover, greatest declines in chlorophyll occurred upstream of the WWTP where
concentrations were low. Grazing by clams and zooplankton could not account for observed losses, suggesting other factors such as hydrodynamics and light limitation were responsible for phytoplankton declines. These results highlight the advantages of conducting ecosystem‐scale, Lagrangian‐based experiments to understand the dynamic and complex interplay between physical, chemical, and biological factors that control phytoplankton populations.
Recipient vessels for microsurgical flaps to the abdomen: A systematic review
Authors: Gurunluoglu Raffi , Rosen Michael J. 
Published: February 2017

AbstractBackgroundLarge soft tissue defects of the abdominal wall resulting from various reasons may require free tissue transfer.MethodsA literature search of PubMed and Cochrane electronic databases was conducted to identify articles involving abdominal wall reconstruction (AWR) with microsurgical flap. Number of cases, etiology, and reconstruction site, type of microsurgical flap and recipient vessels were analyzed.ResultsThirty‐eight articles published between 1983 and 2016 reported on 149 patients undergoing free flap AWR. TFL was used in 43 patients (28.8%), LAD in 43 (28.8%), and ALT in 28 (18.7%). Conjoined ALT and TFL flap was reported in 24 patients (16.1%). The inferior epigastric artery/vein were the most commonly utilized recipient vessels (n = 43 patients). Intraperitoneal vessels were used in 18 cases, the gastroepiploic vessels being the most common (n = 9). Femoral vessels were used directly or along with a vein graft in 14 patients. AV loop or vein graft was reported in 46 patients. Great saphenous vein rerouting was used in 8 cases. DLCF vessels were used in 2 patients to support an AV loop or directly the pedicle of a microsurgical flap. The internal thoracic vessels were used in only 3 patients.ConclusionsThe current review analyzed articles on AWR using microsurgical flaps with a special emphasis on the recipient vessels. The literature review demonstrated that there is no standard approach to repair a complex abdominal defect given the diversity of patient population. The choice of microsurgical flap and selection of recipient vessels should be tailored to the individual patient's circumstances.

ABSTRACTThe use of enzymes as catalyst in polyesters production enables the creation of new materials for use in biomedical applications. In this work, a polyester derived from ω‐pentadecalactone was synthesized. The polymer synthesis was performed using lipase Novozym 435 as catalyst and several solvents at 70 °C. The use of a closed variable volume reactor allowed the use of solvents with a boiling point lower than the reaction temperature, without affecting the ratio of solvent to monomer. Yields above 49 wt% and high molecular weights were obtained for all tested solvents. Dichloromethane (DCM) and chloroform were used as solvents for the evaluation of water content on enzyme and reaction time over the properties of final polymer. The amount of water on enzyme has a direct influence on reaction yields though higher molecular weights were obtained in reactions with lower water content. Yields of around 90 wt% were obtained in 6 h of reaction and molecular weights up to 42,300 and 51,900 g mol−1 were obtained in 2 h of reactions using DCM and chloroform as solvents. © 2016 Wiley Periodicals, Inc.

ABSTRACTProline may work efficiently in water as catalyst of aldol reactions if it is hydrophobically activated. In this work, we have maximized this hydrophobic activation by the preparation of linear alternating copolymers of hydrophobic phenylmaleimide and a vinylpyrrolidone derivative bearing proline. These copolymers were water soluble above pH 5.0 and, unlike the free proline, exhibited efficient catalysis at pH 7.0. Moreover, they catalyzed and presented enantioselectivity in an aggregated form at pH 4.0 (close to the isoelectric point, IEP, of the polymer). This enantioselectivity has been related to the exclusion of water at this IEP. To control the size and stabilize the aggregates, PEG grafted copolymers were prepared by the incorporation of a PEG‐macromer (2–10 mol%), which rendered stable nano‐aggregates in water at the IEP. At this pH they catalyzed the aldol reaction in a higher rate than the non‐grafted polymer, but the enantioselectivity was decreased. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Published: February 2017

ABSTRACTThis work reports on the consequences of concatenation of two twin macrocycles on the gelation behavior of coordination polymers obtained via ring‐opening metathesis polymerization (ROMP) initiated by 2nd generation Grubbs' catalyst. The influence of concatenation is evaluated by comparison with the behavior of a non‐interlocked model complex under the same reaction conditions. The suitability of the choice of the non‐interlocked model complex is discussed in terms of molecular structure and effective molarity (EM). It is found that concatenation has a primary role in the gelation process, resulting in lower critical gelation concentrations for the endotopic, interlocked complex compared with the exotopic, non‐interlocked one. © 2016 Wiley Periodicals, Inc.

Published: February 2017

AbstractWhat will happen when methane is at a temperature of 1500 K? On the first glance the answer seems to be obvious ‐ methane will decompose into hydrogen and one of the forms of carbon. Yes. However is does not do so at very high pressure, when novel reaction pathways become possible. The latest experimental results and theoretical calculations show that methane and heavier hydrocarbons are, remarkably enough, stable under extreme pressures and temperatures. Even more, experiments confirm the possibility of abiogenic synthesis of natural gas at 5.0 GPa and 1500 K. The review summarizes published results of theoretical and experimental investigations of possible pathways under the conditions of pressure and temperature that prevail in the Earth's upper mantle for the formation of (1) particular species of hydrocarbon molecules, and of (2) complex hydrocarbon systems. The results raise fundamental questions on the genesis of hydrocarbons.

Published: February 2017

AbstractThe influence of some newly synthesized pyridinium salts on the structural behavior of two lipid matrices formed with POPC or POPE was investigated by using SAXD. The structural impact / evolution of temperature scans were determined on samples prepared with different pyridinium salts / lipid helper molar ratio compositions, in water. In POPC based samples most complexes showed a strong sensitivity to the presence of pyridinium salts, mostly destructive of the long range order. A clear dependence of the structural behavior was correlated with pyridinium salt concentration. In POPE based samples the conformation of the hydrophobic part of such pyridinium salts seems to have a significant impact on the overall matrix structural behavior.

Published: February 2017

AbstractSolvatochromic and solvatofluoric behaviour of three coumarin rhodamine hybrid dyes (Cou‐Rhod1, Cou‐Rhod2 and Cou‐Rhod3) have been studied in ten different solvents with varying polarity. The pH (1‐10) study was done to investigate the spirocyclic ring opening. All the dyes show charge transfer phenomenon in local as well as charge transfer excitation. The non‐linear optical properties of coumarin rhodamine hybrid dyes were studied using solvatochromic method (highest value of αCT for Cou‐Rhod1=2.44 X 10−23; highest value of βCT for Cou‐Rhod2=0.14 X 10−28 and the highest value of γ for Cou‐Rhod2=0.02 X 10−34) and computational (highest value of α0 for Cou‐Rhod3=9.89 X 10−23; highest value of β0 for Cou‐Rhod1=0.90 X 10−28 and highest value of γ for Cou‐Rhod3=5.10 X 10−34) approach. As the non‐radiative rate constant increases quantum yield of the dyes decreases. Correlation of calculated radiative lifetime (τ), radiative (Kr) and non‐radiative rate constant (Knr) has been made to explain the quantum yield of dyes using Strickler‐Berg equation. The charge transfer behaviour, structural parameters and non‐linear optical properties of the dyes are well described by DFT and TD‐DFT calculations.

AbstractA porphyrin based catalytic system with three metals of Manganese, Zinc and Iron and quaternary ammonium salt as co‐catalyst showed very high selectivity for CO2 fixation reaction of different epoxide monomers for synthesizing cyclic carbonates. The reaction showed quantitative yields under solvent‐free and atmospheric pressure. Quaternary ammonium salts were able to catalyse these reactions singlehandedly, thus their mole ratios were decreased to investigate metalloporphyrins effect. After three cycles of reusing, this catalytic system showed minor reduction in activity and no weight loss. Also, manganese porphyrin has high ability to convert bifunctional epoxides (yield 98% in 4h) and vegetable oil by CO2 (yield 99% in 30h) to cyclic carbonates at ambient condition.
Prediction and Characterization of Alkaline‐Earth (M=Be, Mg, Ca, Sr, and Ba) Metallacyclopentadienes and Relevant Derivatives
Authors: Sun Zhi , Launder Andrew M. , Schaefer Henry F. 
Published: February 2017

AbstractAlkaline‐earth metallacyclopentadienes are an active area of research in synthetic chemistry, notable for their roles as precursors of key cyclopentadiene derivatives. However, experimental characterization is limited due to their challenging synthesis and subsequent isolation. Herein, we report systematic theoretical studies of MC4H4 (M=Be, Mg, Ca, Sr, Ba) rings and experimentally relevant complexes. Benchmarking against CCSD(T) and experiment shows reasonable performance for the B3LYP, BP86, and M06‐2X density functionals in predicting the equilibrium geometries, thermochemistry, and vibrational spectra of these species. NICS indices and extra cyclic resonance energies confirm that the compounds in question possess antiaromatic character. For both the bare MC4H4 rings and larger complexes, the Be‐containing compounds were found to be the most strongly bound species. Such viability is explained via ring strain, electron densities, natural bond orders, and orbital analyses. Given that the second least viable Mg complex has been reported in recent experiments, synthesis and characterization of the other group IIA analogs are anticipated.

AbstractThe valorization of cheap and readily available biomass‐based wastes such as various straws, husks, shells and peels, moreover, so far unprecedented, commercial and household wastes produced on large scale, i. e. spent coffee grounds and cooked tea leaves waste were processed as raw materials for the production of levulinic acid, a C5‐platform molecule. The results obtained by applying conventional and microwave dielectric heating at 170 °C were compared. It was revealed that depending on the source, the average product yields were 10–25 wt% when 2 M aqueous sulfuric acid solution was used. By applying microwave irradiation the reaction time can be significantly reduced (30 min instead of 8 h) without a decrease in product formation. The influence of the feedstock's water content on the formation of levulinic acid was investigated revealing that the drying process having significant energy needs can be eliminated from the procedure.
