Business experience or Financial Literacy? Which one is better for opportunity recognition and superior performance?
Authors: Anwar Muhammad , Shuangjie Li , Ullah Rizwan 
Published: January 2020

AbstractRecognition of useful opportunities is very crucial for small and medium‐sized enterprises' (SMEs') survival and growth in the competitive environment. However, the majority of SMEs cannot easily recognize new opportunities in the turbulent markets due to a lack of managerial competencies and knowledge. Several studies have been carried out to unleash the determinants of opportunity recognition that configure SMEs' success, but the results are disjointed. In particular, the mediating role of opportunity recognition between business experience, financial literacy, and SME performance has been missed. This study aims to test if either financially literate or experienced managers can recognize new opportunities that result in high performance. For testing the hypotheses, we surveyed 232 Pakistani SMEs from the manufacturing, trading, and service sectors. After performing the structural equation modeling, we found that financial literacy and business experience are the substantial prognosticators of opportunity recognition and SMEs' performance. Opportunity recognition shows a partial mediating role between financial literacy and SMEs performance as well as between business experience and SMEs performance. However, this research endorses that business experience is more vital for high performance as compared to financial literacy whereas in terms of opportunity recognition financial literacy is more crucial as compared to experience. This study recommends the enterprises to hire the financially literate and experienced managers as both display a prominent role in the identification of opportunities and high performance. Further implications are discussed.

Published: January 2020

AbstractGiven that entire industries face sustainability challenges, it is important to understand the dynamics that lead “firms‐in‐an‐industry” to engage in sustainable product innovation. To provide more insight into the question of how innovation activities spread from individual firm action to an industry‐wide engagement, this paper examines the automobile industry and the development of electric vehicles (EVs). The analysis covers automobile incumbents over a crucial decade for EV development in the industry, focusing on the different strategic motives that especially the so‐called “first movers” used to justify their earlier engagement. We find that EVs became a core pillar of the incumbents' technology strategies through a combination of coercive, normative, and mimetic pressures. Yet, the strategic motives to engage in EVs stayed poles apart between different companies. The insights from our study are relevant for those interested in the diffusion of sustainable product innovation and in incumbent behaviour in sustainability transitions.

AbstractPurposePrevious studies provide inconsistent interpretations of the effect of inherited genetic factors on the survival and prognosis of patients with breast cancer. The aim of this study was to examine the effect of germline BRCA1 and BRCA2 mutation on survival and subsequent breast events in Chinese women who underwent breast‐conserving surgery.MethodsA retrospective review of the clinical and pathological records was performed in patients diagnosed with primary invasive breast cancer between 2005 and 2018 in the cancer registry database. Clinicopathological data and data regarding treatment and outcomes, including date and site of disease progression, were collected. The survival outcomes and independent risk factors were conducted using SPSS.ResultsOverall, a total of 501 patients who underwent breast‐conserving surgery were identified and subjected to analyses, of which 63 cases with BRCA1 or BRCA2 mutation. The median age at diagnosis was 41 (range, 24‐74) for carriers and 37 (range, 17‐84) for noncarriers. After a median follow‐up time of 61 months (range, 8‐161) and 70 months (range, 0‐153), respectively, in carriers and noncarriers, the overall survival (P = .173) and disease‐free survival (P = .424) were not significantly different. Analogously, there was no significant difference between the two groups about the outcomes of ipsilateral breast tumor recurrence (P = .348), yet the contralateral breast cancer (CBC) was overt worse than noncarriers (P < .001). When adjusted to confounding factors, BRCA mutation was the only independent risk factors to CBC (HR = 7.89, P = .01).ConclusionIn this study, BRCA mutation carriers have higher risk of CBC. And, BRCA mutation is the only independent risk factor to CBC. Therefore, intensive surveillance and follow‐up as well as more effective individual prevention are urgent. Decisions on alternatively effective prevention, especially the prevention of CBC, are urgent and should take into account patient prognosis and preferences.

Published: January 2020

AbstractDeveloping effective and eco‐friendly antimicrobials and pesticides has become a highly important issue. The repellent, insecticidal and antimicrobial activity of essential oils (EOs) isolated by hydrodistillation from dried leaves of the three Eucalyptus species (E. cloeziana, E. umbellata and E. benthamii) were investigated. During GC/MS analysis, α‐pinene (47.36 %), 1,8‐cineol (38.53 %) and α‐pinene (35.31 %) were identified as major components of E. cloeziana, E. umbellata and E. benthamii, respectively. The EOs from E. cloeziana exhibited the longest effective protection time (465 min, at 50.0 % w/w) for humans among the EOs studied. The effective protection time was 30 min and 300 min at concentrations of 12.5 % (w/w) and 25.0 % (w/w), respectively. Fumigating insecticidal activity of EOs from three Eucalyptus species was tested by airtight fumigation in conical flask, which indicated that essential oils had a highly and rapidly insecticidal activity on Culex pipiens quinquefasciatus. The antimicrobial activity of EOs was evaluated by using disc diffusion and agar dilution methods. There was no significant difference in the antibacterial activity of EOs from E. cloeziana and E. umbellate and they had the same MICs (20 mL/L) on Staphylococcus aureus, Salmonella typhi, Bacillus subtilis and Escherichia coli. E. benthamii had the worst microbial inhibitory effect among the three Eucalyptus essential oils and the MIC value for the test species is 40 mL/L except for Rhodotorula Harrison (10 mL/L).

Published: January 2020

AbstractA new concept, referred to as key‐lock catalyst, is presented in this article. Soot combustion ceria catalysts were prepared combining hard (polymethylmethacrylate colloidal crystals) and soft (Pluronic F127) templates, tuning the porosity of ceria in different size ranges to match the morphology of soot aggregates. The catalysts porosity was characterized in detail by N2 adsorption‐desorption isotherms and Hg‐porosimetry. XRD and H2‐TPR characterization ruled out that differences in activity are related neither with crystallographic nor with redox properties. As a proof of key‐lock catalyst concept, an optimum key‐lock ceria catalyst was synthesized by combining large macropores (100–300 nm) with mesopores (10–30 nm), because they fit to the large soot aggregates and to primary soot particles sizes, respectively. The best soot combustion activity of the optimum key‐lock catalyst is attributed to the optimum transfer of ceria active oxygen from catalyst to soot. The catalytic results confirmed that all ceria catalysts prepared with different porosity oxidize NO to NO2 at the same rate, and the NO2‐assisted soot combustion pathway is not affected by tuning ceria porosity. This double‐templated synthesis and the key‐lock concept opens a new synthesis approach to design noble‐metal free soot combustion catalysts based on the highly effective active oxygen mechanism.

Published: January 2020

AbstractThe dry tray pressure drop (ΔPd) is a design parameter that provides preliminary information about the total pressure drop. This work aimed to assess correlations for ΔPd prediction for different types of trays without downcomer and to evaluate the effects of the free area ratio (φ) and the hole diameter (d) on ΔPd. Assessment was performed by comparing results of several correlations with those from an experimentally validated computational fluid dynamics simulation. The study shows that the correlations of Červenka and Kolář, Bennett, Agrawal and Cook, and Stichlmair and Mersmann predicted the dry pressure drop satisfactorily. The correlation of Bennett, Agrawal and Cook can be recommended for the prediction of ΔPd for a wide range of geometries and operation conditions. Also, φ has a higher influence on ΔPd than d.
Divergent 2‐Chloroquinazolin‐4(3H)‐one Rearrangement: Twisted‐Cyclic Guanidine Formation or Ring‐Fused N‐Acylguanidines via a Domino Process

Published: January 2020

AbstractA highly efficient 2‐chloroquinazolin‐4(3H)‐one rearrangement was developed that predictably generates either twisted‐cyclic or ring‐fused guanidines in a single operation, depending on the presence of a primary versus secondary amine in the accompanying diamine reagent. Exclusive formation of twisted‐cyclic guanidines results from pairing 2‐chloroquinazolinones with secondary diamines. Use of primary amine‐containing diamines permits a domino quinazolinone rearrangement/intramolecular cyclization, gated through (E)‐twisted‐cyclic guanidines, to afford ring‐fused N‐acylguanidines. This scalable, structurally tolerant transformation generated 55 guanidines and delivered twisted‐cyclic guanidines with robust plasma stability and an abbreviated total synthesis of an antitumor ring‐fused guanidine (4 steps, 55 % yield).
Screening young adult cancer survivors with the PROMIS Depression Short Form (PROMIS‐D‐SF): Comparison with a structured clinical diagnostic interview
Authors: Recklitis Christopher J. , Blackmon Jaime E. , Chang Grace 
Published: January 2020

BackgroundThe current study was conducted to evaluate the Patient‐Reported Outcomes Measurement Information System Depression Short Form (PROMIS‐D‐SF) as a screening measure for young adult cancer survivors (YACS) compared with a structured diagnostic interview.MethodsA total of 249 YACS (aged 18‐40 years) completed the PROMIS‐D‐SF and Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (SCID). Based on the SCID, participants were classified as having: 1) an SCID depression diagnosis; 2) depression symptoms without an SCID diagnosis; or 3) no depression symptoms. Receiver operating characteristic analyses evaluated PROMIS‐D‐SF and SCID concordance and the sensitivity and specificity of PROMIS‐D‐SF cutoff t ‐scores.ResultsThe PROMIS‐D‐SF had overall good agreement with the SCID for both depression diagnosis (area under the curve, 0.89) and the presence of depressive symptoms (area under the curve, 0.83). A PROMIS‐D‐SF cutoff t‐score of ≥53.2 came closest to meeting study criteria for detecting a SCID depression diagnosis (sensitivity ≥0.85 and specificity ≥0.75), with a sensitivity of 0.81 and a specificity of 0.74. For identifying survivors with depression symptoms, a t‐score cutoff value of 49.4 was found to have slightly superior sensitivity (0.84) and inferior specificity (0.64). In hypothetical screening examples, these cutoff scores led to moderate levels of missed cases (15%‐19%) and a high percentage of clinical referrals that were unnecessary by SCID criteria (56%‐70%).ConclusionsThe PROMIS‐D‐SF demonstrated moderately strong concordance with depressive diagnoses and symptoms measured by the SCID, but cutoff t‐scores did not meet study criteria for clinical screening. The PROMIS‐D‐SF may be useful for assessing depression in YACS, but the limitations in its sensitivity and specificity identified in the current study are likely to limit its usefulness as a stand‐alone screening instrument in this population.

BackgroundPatients with cancer who are treated with immune checkpoint modulators (ICMs) have their health‐related quality of life (HRQOL) measured using general patient‐reported outcome (PRO) tools. To the authors' knowledge, no instrument has been developed to date specifically for patients treated with ICMs. The objective of the current study was to develop a toxicity subscale PRO instrument for patients treated with ICMs to assess HRQOL.MethodsInput was collected from a systematic review as well as patients and physicians experienced with ICM treatment. Descriptive thematic analysis was used to evaluate the qualitative data obtained from patient focus groups and interviews, which informed an initial list of items that described ICM side effects and their impact on HRQOL. These inputs informed item generation and/or reduction to develop a toxicity subscale.ResultsFocus groups and individual interviews with 37 ICM‐treated patients generated an initial list of 176 items. After a first round of item reduction that produced a shortened list of 76 items, 16 physicians who care for patients who are treated with ICMs were surveyed with a list of 49 patient‐reported side effects and 11 physicians participated in follow‐up interviews. A second round of item reduction was informed by the physician responses to produce a list of 25 items.ConclusionsTo the authors' knowledge, this 25‐item list is the first HRQOL‐focused toxicity subscale for patients treated with ICMs and was developed in accordance with US Food and Drug Administration guidelines, which prioritize patient input in developing PRO tools. The subscale will be combined with the Functional Assessment of Cancer Therapy–General (FACT‐G) to form the FACT‐ICM. Prior to recommending the formal use of this PRO instrument, the authors will evaluate its validity and reliability in longitudinal studies involving substantially more patients.
Efficient Plastic Waste Recycling to Value‐Added Products by Integrated Biomass Processing
Authors: Beydoun Kassem , Klankermayer Jürgen 
Published: January 2020

AbstractThe industrial production of polymeric materials is continuously increasing, but sustainable concepts directing towards a circular economy remain rather elusive. The present investigation focuses on the recycling of polyoxymethylene polymers, facilitated through combined catalytic processing of polymer waste and biomass‐derived diols. The integrated concept enables the production of value‐added cyclic acetals, which can flexibly function as solvents, fuel additives, pharmaceutical intermediates, and even monomeric materials for polymerization reactions. Based on this approach, an open‐loop recycling of these waste materials can be envisaged in which the carbon content of the polymer waste is efficiently utilized as a C1 building block, paving the way to unprecedented possibilities within a circular economy of polyoxymethylene polymers.

Published: January 2020

AbstractLithium‐ion batteries (LIBs) providing high energy and power densities as well as long cycle life are in high demand for various applications. Benefitting from its high theoretical specific charge capacity of ≈4200 mAh g−1 and natural abundance, Si is nowadays considered as one of the most promising anode candidates for high‐energy‐density LIBs. However, its huge volume change during cycling prevents its widespread commercialization. Si/C‐based electrodes, fabricated through top‐down mechanical‐milling technique and etching, could be particularly promising since they can adequately accommodate the Si volume expansion, buffer the mechanical stress, and ameliorate the interface/surface stability. In this Review, the current progresses in the top‐down synthesis of Si/C anode materials for LIBs from inexpensive Si sources via the combination of low‐cost, simple, scalable, and efficient ball‐milling and etching processes are summarized. Various Si precursors as well as etching routes are highlighted in this Review. This review would be a guide for fabricating high‐performance Si‐based anodes.
An assessment of chamber 14C methodologies for sampling aquatic CO2 evasion
Authors: Billett Michael F. , Garnett Mark H. , Leith Fraser I. 
Published: January 2020

AbstractThe development of new methods to directly measure the radiocarbon age of dissolved and evaded aquatic carbon dioxide has enhanced our ability to understand carbon transport and cycling in the soil–water–atmosphere system. One of the methods involves collecting enough carbon dioxide for radiocarbon dating by allowing carbon dioxide to outgas from the water surface into an enclosed floating chamber, with the gas subsequently trapped onto a zeolite molecular sieve cartridge. There are, however, several different methodological approaches that can be used for the collection of floating chamber samples, and it is currently unknown whether these different approaches influence the isotopic (stable carbon and radiocarbon) composition of the measured sample. Here, we evaluate four different floating chamber approaches and compare the stable and radiocarbon composition of the evaded carbon dioxide. Chamber conditions varied considerably with the different methodologies, with for example, maximum chamber CO2 concentration ranging from approximately 400–6,300 ppm during sampling. Despite the varying chamber conditions, our results indicate no significant differences in the 14C age of evasion (range: 1,276–1,364 years before present) with any of the methodological approaches (in chambers where atmospheric carbon dioxide had been excluded). This confirms the methodologies are both robust and widely applicable.
Aspects of bridge‐ground seismic response and liquefaction‐induced deformations

Published: January 2020

SUMMARYConsiderable bridge‐ground interaction effects are involved in evaluating the consequences of liquefaction‐induced deformations. Due to seismic excitation, liquefied soil layers may result in substantial accumulated permanent deformation of sloping ground near the abutments. Ultimately, global response is dictated by the bridge‐ground interaction as an integral system. However, a holistic assessment of such response generally requires a highly demanding full three‐dimensional (3D) model of the bridge and surrounding ground. As such, in order to capture a number of the salient involved mechanisms, this study focuses on the longitudinal seismic performance of a simpler idealized configuration, motivated by details of an existing bridge‐ground configuration. In this model, a realistic multilayer soil profile is considered with interbedded liquefiable/nonliquefiable strata. The effect of the resulting liquefaction‐induced ground deformation is explored. Attention is given to overall deformation of the bridge structure due to lateral spreading in the vicinity of the abutments. The derived insights indicate a need for such global analysis techniques, when addressing the potential hazard of liquefaction and its consequences.
Assessment of CO2‐enhanced oil recovery and associated geologic storage potential in the Michigan Northern Pinnacle Reef Trend

Published: January 2020

AbstractThis paper provides an improved estimate of CO2‐EOR (where CO2 is carbon dioxide and EOR is enhanced oil recovery) and CO2 storage potential for depleted oil fields in Michigan's northern pinnacle reef trend (NPRT). Our methodology is based on capturing data on reservoir performance from reefs currently undergoing CO2‐EOR operations in the NPRT (referred to as ‘monitored reefs’), and then applying them to other reefs within the NPRT (referred to as ‘catalog reefs’). For each monitored reef, we calculate fractional primary recovery, fractional incremental EOR recovery, net utilization ratio, and storage efficiency factor. The corresponding incremental oil recovery from EOR, storage capacity until end of EOR, and total CO2 injection needs are then estimated for each catalog reef and combined (over all monitored reefs) using a weighted averaging procedure. These weights are related to a statistical similarity measure that is calculated between each monitored reef and each catalog reef based on a number of variables related to production data, formation type, or descriptive geologic attributes. For the entire NPRT catalog of 383 reefs as used in this study, our results indicate 118 million (MM) stock tank barrels (STB) (1.88 × 107 Sm3) of incremental oil from EOR operations, corresponding to 49 MM metric tons (MT) of CO2 storage and 266 MM MT of total CO2 injection. However, approximately one‐third of the reefs provide two‐thirds of the potential for CO2‐EOR and geologic storage, assuming an economic threshold of 0.5 MM STB (80 000 Sm3) of incremental oil from EOR. © 2020 The Authors.
