Published: December 2017

AbstractSeveral authors have suggested a deep symmetry between the psychological processes that underlie our ability to remember the past and make predictions about the future. The judgment of recency (JOR) task measures temporal order judgments for the past by presenting pairs of probe stimuli; participants choose the probe that was presented more recently. We performed a short-term relative JOR task and introduced a novel judgment of imminence (JOI) task to study temporal order judgments for the future. In the JOR task, participants were presented with a sequence of stimuli and asked to choose which of two probe stimuli was presented closer to the present. In the JOI task, participants were trained on a probabilistic sequence. After training, the sequence was interrupted with probe stimuli. Participants were asked to choose which of two probe stimuli was expected to be presented closer to the present. Replicating prior work on JOR, we found that RT results supported a backward self-terminating search model operating on a temporally-organized representation of the past. We also showed that RT distributions are consistent with this model and that the temporally-organized representation is compressed. Critically, results for the JOI task probing expectations of the future were mirror-symmetric to results from memory, suggesting a forward self-terminating search model operating on a temporally-organized representation of the future.

PurposeThe role of entrepreneurship has changed to include issues beyond economic growth. This has turned attention toward the drivers of entrepreneurial intentions across entrepreneurship types, particularly in sustainable entrepreneurship. The purpose of this paper is to examine the drivers of entrepreneurial intentions in sustainable entrepreneurship. In particular, the paper aims to extend the existing intention models to include work values and attitudes toward sustainability, thereby bringing the model into the context of sustainable entrepreneurship.Design/methodology/approachUsing a quantitative research design, data were collected in three European countries through anonymous questionnaires. The data consist of responses from 393 university students.FindingsThe results show that attitude toward sustainability and perceived entrepreneurial desirability enhance sustainability-oriented entrepreneurial intentions. Moreover, adding sustainability into the regression equation adds explanation power, hence suggesting that the theory of planned behavior needs to be adapted when applied to sustainable entrepreneurship. Attitudes toward sustainability are positively impacted by altruism, while perceived entrepreneurial desirability is driven by intrinsic and extrinsic rewards.Research limitations/implicationsThe study focuses on one particular type of entrepreneurship and one particular age group.Originality/valueThe paper contributes to the entrepreneurship literature by applying the entrepreneurial intention model to sustainable entrepreneurship. The results imply that it may be the time to consider the variance in entrepreneurial opportunities in intention models as well as the need to address the conflict between work values. The results show that sustainability-oriented entrepreneurial intentions are driven by attitudes toward sustainability and perceived entrepreneurial desirability. These two attitudes are driven by altruism and extrinsic rewards, and, especially, extrinsic reward plays an opposite role in both drivers of sustainability-oriented entrepreneurial intentions.
Audit costs of small cities in an unregulated audit market environment
Authors: Brown Ken W. , Margavio Thomas M. 
Published: December 2017

This study provides public administrators with an introduction into research of the determinants of audit fees. A working knowledge of external audit cost determinants can help public administrators hone their evaluation skills for use in audit-procurement. Most prior research on audit cost determinants has focused on the few hundred cities in the nation with populations exceeding 50,000. As a result, this study investigated the audit costs incurred by small cities with populations less than 50,000.
Besides providing a glimpse of small-city auditing practices, the study tested the significance of the Single Audit Act in audit-fee determination. Missouri municipalities with populations between 2,000 and 50,000 provided the sample for the study. Because Missouri is one of the few states in the nation that neither legislates nor monitors municipal auditing, it represents an unregulated audit market in which town officials decide on the need for an audit, the firm to conduct the audit, and the process by which the audit firm is selected. The results of a nine-variable regression model suggested that the size of the town, the existence of a city administrator, the complexity of the town's operation, the method of accounting, the timing and completion time of the audit, and audit-firm specialization in municipal auditing were important determinants of audit fees.

Published: December 2017

AbstractTo develop a robust tool for Chinese commercial wines’ varietal, regional, and vintage authentication, phenolic compounds in 121 Chinese commercial dry red wines were detected and quantified by using high‐performance liquid chromatography triple‐quadrupole mass spectrometry (HPLC‐QqQ‐MS/MS), and differentiation abilities of principal component analysis (PCA), partial least squares discriminant analysis (PLS‐DA), and orthogonal partial least squares discriminant analysis (OPLS‐DA) were compared. Better than PCA and PLS‐DA, OPLS‐DA models used to differentiate wines according to their varieties (Cabernet Sauvignon or other varieties), regions (east or west Cabernet Sauvignon wines), and vintages (young or old Cabernet Sauvignon wines) were ideally established. The S‐plot provided in OPLS‐DA models showed the key phenolic compounds which were both statistically and biochemically significant in sample differentiation. Besides, the potential of the OPLS‐DA models in deeper sample differentiating of more detailed regional and vintage information of wines was proved optimistic. On the basis of our results, a promising theoretic design for wine authentication was further proposed for the first time, which might be helpful in practical authentication of more commercial wines.Practical ApplicationThe phenolic data of 121 Chinese commercial dry red wines was processed with different statistical tools for varietal, regional, and vintage differentiation. A promising theoretical design was summarized, which might be helpful for wine authentication in practical situation.

AbstractObjectivesNumerous systematic reviews investigating the efficacy of platelet‐rich plasma (PRP) in treating knee osteoarthritis (OA) have been recently published. The purpose of the present study was (1) to perform an overview of overlapping systematic reviews investigating PRP for knee OA via evaluating methodological quality and risk of bias of systematic reviews and (2) to provide recommendations through the best evidence.MethodsA systematic search of systematic reviews published through Feb 2017 was conducted using the MEDLINE, EMBASE and Cochrane Library. The methodological quality and risk of bias of included systematic reviews were assessed by AMSTAR instrument and ROBIS tool respectively. Best evidence choice procedure was conducted according to the Jadad decision algorithm. The systematic reviews with high quality of methodology and low risk of bias were selected ultimately.ResultsTen systematic reviews were eligible for inclusion. The Jadad decision making tool suggested that the reviews with highest AMSTAR score should be selected. According to the ROBIS tool, there were 4 systematic reviews with low risk of bias and 6 with high risk of bias. As a result, two systematic reviews conducted by Dai et al and Meheux et al with highest AMSTAR score and low risk of bias were selected as the best evidence.ConclusionsThe present overview demonstrates that PRP is an effective intervention in treating knee OA without increased risk of adverse events. Therefore, the present conclusions may help decision makers interpret and choose PRP with more confidence.

AbstractSafe preservation of the remnant stomach during distal gastrectomy in patients who have undergone distal pancreatectomy is important. During distal pancreatectomy, the splenic artery that supplies arterial blood to the cardiac part of stomach is resected. Previous reports suggested that blood flow to the remnant stomach may be insufficient when supplied by only the left inferior phrenic artery. In the present case, a 79‐year‐old woman who underwent distal pancreatectomy with splenectomy 20 years before she was diagnosed with gastric cancer and referred to our hospital. We performed laparoscopic distal gastrectomy and Roux‐en‐Y reconstruction because preoperative CT scan indicated a developed left inferior phrenic artery. To evaluate the blood supply, we employed indocyanine green fluorescence and were able to safely preserve the remnant stomach. Our experience suggests that indocyanine green fluorescence is potentially useful for evaluating blood flow to the remnant stomach.

AbstractBackgroundVery long‐term follow‐up of oral implants is seldom reported in the literature.PurposeTo assess oral implant failure rates and marginal bone loss (MBL) of patients followed up for a minimum of 20 years.Materials and MethodsImplants placed in patients followed up for 20+ years were included. Descriptive statistics, survival analyses, generalized estimating equations were performed. Three‐hundred implants were randomly selected for MBL.Results1,045 implants (227 patients) were included. Implant location, irradiation, and bruxism affected the implant survival rate. Thirty‐five percent of the failures occurred within the first year after implantation, and another 26.8% in the second/third year. There was a cumulative survival rate of 87.8% after 36 years of follow‐up. In the last radiological follow up, 35 implants (11.7%) had bone gain, and 35 implants (11.7%) presented at least 3 mm of MBL. Twenty‐six out of 86 failed implants with available radiograms presented severe MBL in the last radiological register before implant failure.ConclusionsMost of the implant failures occurred at the first few years after implantation, regardless of a very long follow up. MBL can be insignificant in long‐term observations, but it may, nevertheless, be the cause of secondary failure of oral implants in some cases.
Phengaris (Maculinea) teleius butterflies select host plants close to Myrmica ants for oviposition, but P. nausithous do not
Authors: Wynhoff Irma , van Langevelde Frank 
Published: December 2017

AbstractMany lycaenid butterfly species have interactions with ants, with 12% obligatorily depending on two sequential sources of larval food, namely host plants and host ants. When host plants are abundant but the density of host ant nests is relatively low, most host plants have no host ant nest in their vicinity and are thus unsuitable for larval survival. Obligatorily myrmecophilous female butterflies, whose caterpillars feed on ant larvae, would have a comparative advantage if they deposit eggs on host plants in the proximity of a host ant nest. However, this ant‐mediated oviposition has been hotly debated. In an open‐air insectory experiment, we tested whether oviposition is ant‐mediated or not for two obligatory myrmecophilous butterfly species, Phengaris (Maculinea) nausithous Bergsträsser and Phengaris teleius Bergsträsser (Lepidoptera: Lycaenidae). Female butterflies could select host plants close to either no ant nest or a nest of one of the two Myrmica species (Hymenoptera: Formicidae) that are thought to be their host ant. Our results support ant‐mediated oviposition in P. teleius, but also indicate that there is no preference for either of the Myrmica species. More eggs were deposited and more caterpillars were found on long flowerheads close to Myrmica ant nests than on those without nests. Our findings suggest that ant presence is more important than flowerhead phenology for females of P. teleius. In contrast, P. nausithous females were not attracted by ants but preferred long flowerheads with a low percentage of green coloration. With these findings, this study contributes to better understanding of the habitat requirements of two highly specialized butterfly species.
Where should I lay my eggs? Oviposition choices of a shelter‐building moth and the shifting danger of being parasitized
Authors: Morse Douglass H. 
Published: December 2017

AbstractYoung unable to move freely depend on their parents to place them in sites with superior resources or protection from unfavorable factors. The preference‐performance hypothesis holds that females should oviposit on sites that maximize the performance of their offspring. Shelters may provide their inhabitants with superior food resources, protection from enemies, and ameliorated physical factors. Accordingly, one might predict that females would prefer shelters to alternatives, since they might provide enemy‐free space. However, Herpetogramma theseusalis (Walker) (Lepidoptera: Crambidae) fern moths oviposited both in shelters constructed on sensitive ferns (Onoclea sensibilis L., Dryopteridaceae) and on exposed fern pinnae, perhaps as a bet‐hedging tactic. The moths laid eggs on the outer parts of the shelters, but after hatching the young caterpillars moved toward the center of the shelters, often beyond the reach of their common larval parasitoid, Alabagrus texanus (Cresson) (Hymenoptera: Braconidae). Although caterpillars in both areas grew at the same rate, those in shelters were parasitized less frequently than those on exposed pinnae. However, shelters senesced from the center to the periphery, depriving the caterpillars of progressively more of their food source and eventually forcing them into the open, potentially increasing their vulnerability. But numbers of wasps decreased simultaneously; hence, most caterpillars were not exposed until danger from the parasitoids had greatly diminished. Thus, offspring of females ovipositing in shelters experienced superior success, consistent with the preference‐performance hypothesis, but through lowered mortality via use of enemy‐free space, rather than superior feeding conditions.
A field study with geometrid moths to test the coevolution hypothesis of red autumn colours in deciduous trees

Published: December 2017

AbstractRed autumn colouration of trees is the result of newly synthesized anthocyanin pigments in senescing autumn leaves. As anthocyanin accumulation is costly and the trait is not present in all species, anthocyanins must have an adaptive significance in autumn leaves. According to the coevolution hypothesis of autumn colours, red autumn leaves warn herbivorous insects – especially aphids that migrate to reproduce in trees in the autumn – that the tree will not be a suitable host for their offspring in spring due to a high level of chemical defence or lack of nutrients. The signalling allows trees to avoid herbivores and herbivores to choose better host trees. In this study the coevolution hypothesis was tested with four deciduous tree species that have red autumn leaf colouration – European aspen (Populus tremula L.) (Salicaceae), rowan (Sorbus aucuparia L.) (Rosaceae), mountain birch [Betula pubescens ssp. czerepanovii (NI Orlova) Hämet‐Ahti], and dwarf birch (Betula nana L.) (Betulaceae), and with two generalist herbivores, the autumnal moth [Epirrita autumnata (Borkhausen)] and the winter moth [Operophtera brumata (L.)] (both Lepidoptera: Geometridae). Anthocyanin concentrations of autumn leaves were determined from leaf samples and the growth performance parameters of the moth larvae on the study trees were measured in the spring. Trees with higher anthocyanin concentration in the autumn were predicted to be low‐quality food for the herbivores. Our results clearly showed that anthocyanin concentration was not correlated with the growth performance of the moths in any of the studied tree species. Thus, our study does not support the coevolution hypothesis of autumn colours.
Drought stress affectsSolanum lycopersicumsusceptibility toBactericera cockerellicolonization
Authors: Huot Ordom Brian , Tamborindeguy Cecilia 
Published: December 2017

AbstractRecent outbreaks in plant diseases associated withLiberibacterpathogens have impacted large areas of western and southern North America. The increase in frequency and severity of drought could render plants more susceptible to the colonization by insect vectors. Experiments were conducted in a laboratory setting to evaluate the influence of water scarcity on drought stress of tomato plants,Solanum lycopersicumL. (Solanaceae). Weekly water treatment of 200, 100, and 50 ml resulted in unstressed (control, Ψw = −0.55 MPa), lowly drought‐stressed (LDS, Ψw = −0.70MPa), and moderately drought‐stressed (MDS, Ψw = −0.87MPa) plants, respectively. By controlling for both water availability and plant drought stress, the effect of drought stress onS. lycopersicumsusceptibility to potato psyllid,Bactericera cockerelli(Šulc) (Hemiptera:Triozidae), was evaluated. In a no‐choice experiment,MDSplants had significantly moreB. cockerellinymphs than control plants. However, plant susceptibility toB. cockerellicolonization was not due to the oviposition preference forMDS, but rather to the higherB. cockerellinymphal survival onMDSthan on control plants. Nymphal survival ofB. cockerellionMDSplants was consistently and significantly higher than on control plants. Throughout all nymphal stages,B. cockerellihad higher survival onMDSplants than on control plants. Drought stress not only enhancedB. cockerellisurvival onS. lycopersicumbut it also resulted in 60% more adults produced on water‐stressed plants than on control plants. Therefore, as adults can move from plant to plant, drought stress could increaseB. cockerelli's dispersion potential. Although plant drought stress improvedB. cockerellisurvival, it did not affectB. cockerellioviposition. No difference in number of offspring was found betweenB. cockerelliadults that developed onMDSvs. control plants. These results might be relevant toB. cockerellioutbreaks andLiberibacterepidemics.

BackgroundThe attributable fraction of influenza virus detection to illness (INF‐AF) and the duration of symptoms as a surveillance inclusion criterion could potentially have substantial effects on influenza disease burden estimates.MethodsWe estimated rates of influenza‐associated influenza‐like illness (ILI) and severe acute (SARI‐10) or chronic (SCRI‐10) respiratory illness (using a symptom duration cutoff of ≤10 days) among HIV‐infected and HIV‐uninfected patients attending 3 hospitals and 2 affiliated clinics in South Africa during 2013‐2015. We calculated the unadjusted and INF‐AF‐adjusted rates and relative risk (RR) due to HIV infection. Rates were expressed per 100 000 population.ResultsThe estimated mean annual unadjusted rates of influenza‐associated illness were 1467.7, 50.3, and 27.4 among patients with ILI, SARI‐10, and SCRI‐10, respectively. After adjusting for the INF‐AF, the percent reduction in the estimated rates was 8.9% (rate: 1336.9), 11.0% (rate: 44.8), and 16.3% (rate: 22.9) among patients with ILI, SARI‐10, and SCRI‐10, respectively. HIV‐infected compared to HIV‐uninfected individuals experienced a 2.3 (95% CI: 2.2‐2.4)‐, 9.7 (95% CI: 8.0‐11.8)‐, and 10.0 (95% CI: 7.9‐12.7)‐fold increased risk of influenza‐associated illness among patients with ILI, SARI‐10, and SCRI‐10, respectively. Overall 34% of the estimated influenza‐associated hospitalizations had symptom duration of >10 days; 8% and 44% among individuals aged <5 and ≥5 years, respectively.ConclusionThe marginal differences between unadjusted and INF‐AF‐adjusted rates are unlikely to affect policies on prioritization of interventions. HIV‐infected individuals experienced an increased risk of influenza‐associated illness and may benefit more from annual influenza immunization. The use of a symptom duration cutoff of ≤10 days may underestimate influenza‐associated disease burden, especially in older individuals.
Acute exposure to high‐induction electromagnetic field affects activity of model peripheral sensory neurons

Published: December 2017

AbstractExposure to repetitive low‐frequency electromagnetic field (LF‐EMF) shows promise as a non‐invasive approach to treat various sensory and neurological disorders. Despite considerable progress in the development of modern stimulation devices, there is a limited understanding of the mechanisms underlying their biological effects and potential targets at the cellular level. A significant impact of electromagnetic field on voltage‐gated calcium channels and downstream signalling pathways has been convincingly demonstrated in many distinct cell types. However, evidence for clear effects on primary sensory neurons that particularly may be responsible for the analgesic actions of LF‐EMF is still lacking. Here, we used F11 cells derived from dorsal root ganglia neurons as an in vitro model of peripheral sensory neurons and three different protocols of high‐induction magnetic stimulation to determine the effects on chemical responsiveness and spontaneous activity. We show that short‐term (<180 sec.) exposure of F11 cells to LF‐EMF reduces calcium transients in response to bradykinin, a potent pain‐producing inflammatory agent formed at sites of injury. Moreover, we characterize an immediate and reversible potentiating effect of LF‐EMF on neuronal spontaneous activity. Our results provide new evidence that electromagnetic field may directly modulate the activity of sensory neurons and highlight the potential of sensory neuron‐derived cell line as a tool for studying the underlying mechanisms at the cellular and molecular level.
