Reply to Cerling et al.

As we previously noted (White et al. 2010), Cerling and colleagues’ (2010, 2011) model for interpreting the relationship between paleosol carbon isotope values and percentage of woody plant cover differs substantially from that used in all previous studies, including those by the coauthors of Cerling et al. 2010 (Cerling 1984; Fox and Koch 2003; Kingston 2007; Levin et al. 2008; Wynn 2004). Their new model has two serious deficiencies. First, they use data from sites with sandy soils that are known to support lower grass biomass than finegrained fertile soils (Bell 1982; Sankaran et al. 2005). This results in lower δC values. Second, they include deep forest sites that have extremely negative δC values due to the closed canopy effect, which shifts the C3 end-member value to lower values than applicable to drier settings relevant here. Thus, their model underestimates percentage of woody cover when applied to Ardipithecus ramidus–bearing sites characterized by fine-grained distal floodplain soils formed on fertile volcanic parent materials. In their current critique (Cerling et al. 2014, in this issue; Dominguez-Rodrigo 2014, comment by Tim D. White), they use a variety of configurations of eastern African soil isotopic data, but they still have not considered the relationship between soil properties and tree-grass ratios. In Cerling et al.’s (2011) modern African data, soil δC values appear on average 2‰ lower on sites that probably represent sandy soils, such as those formed on weathered Basement Complex rocks, coastal sands, Kalahari sands, or high-energy floodplains. Cerling et al. (2014, in this issue, fig. 1) show a “cumulative probability distribution” of woody cover from Aramis that differs from their previous reconstruction (Cerling et al. 2010). Their original presentation had Aramis woody cover “average” 17%, with a 2–standard deviation (SD) range of 0%–35%, which means virtually all localities would have been grassland. In the revised estimate based on eastern African control data, Aramis woody cover “averages” 25%, with a 2-SD range of 5%–45%. This is a modest but meaningful difference, because the latter suggests a greater mosaic of habitats. However, as discussed above, it is probable that their model still underestimates woody cover in the Aramis member sites. We have consistently concluded that the range of habitats
Expanding the boundaries of work—family research: A review and agenda for future research

Given the dominance of work—family research within the context of the United States and a disparate and fractured understanding of the dynamic interplay between work and family for those who live and work beyond the borders of the United States, we review and synthesize 219 empirical work—family studies that have targeted employees outside of the United States. Our review answers four questions about international work—family research. First, what constitutes the work—family interface and is there consensus about how to measure it? Second, what theories have researchers used to explain the work—family interface? Third, which antecedents and consequences of the work—family interface are common across countries and which are unique to particular countries? Fourth, what can we learn from this review that will inform future research in this area? Based on our review, a universal theoretical framework that integrates both work—family conflict and facilitation is provided. Future research directions are also discussed.
Cardioprotection evoked by remote ischaemic preconditioning is critically dependent on the activity of vagal pre-ganglionic neurones

Aims Innate mechanisms of inter-organ protection underlie the phenomenon of remote ischaemic preconditioning (RPc) in which episode(s) of ischaemia and reperfusion in tissues remote from the heart reduce myocardial ischaemia/reperfusion injury. The uncertainty surrounding the mechanism(s) underlying RPc centres on whether humoral factor(s) produced during ischaemia/reperfusion of remote tissue and released into the systemic circulation mediate RPc, or whether a neural signal is required. While these two hypotheses may not be incompatible, one approach to clarify the potential role of a neural pathway requires targeted disruption or activation of discrete central nervous substrate(s). Methods and results Using a rat model of myocardial ischaemia/reperfusion injury in combination with viral gene transfer, pharmaco-, and optogenetics, we tested the hypothesis that RPc cardioprotection depends on the activity of vagal pre-ganglionic neurones and consequently an intact parasympathetic drive. For cell-specific silencing or activation, neurones of the brainstem dorsal motor nucleus of the vagus nerve (DVMN) were targeted using viral vectors to express a Drosophila allatostatin receptor (AlstR) or light-sensitive fast channelrhodopsin variant (ChIEF), respectively. RPc cardioprotection, elicited by ischaemia/reperfusion of the limbs, was abolished when DVMN neurones transduced to express AlstR were silenced by selective ligand allatostatin or in conditions of systemic muscarinic receptor blockade with atropine. In the absence of remote ischaemia/reperfusion, optogenetic activation of DVMN neurones transduced to express ChIEF reduced infarct size, mimicking the effect of RPc. Conclusion These data indicate a crucial dependence of RPc cardioprotection against ischaemia/reperfusion injury upon the activity of a distinct population of vagal pre-ganglionic neurones.

Culture Shock in a Global World: Factors Affecting Culture Shock Experienced by Expatriates in Oman and Omani Expatriates Abroad

The purpose of the paper is to investigate various forms of culture shock experienced by people who visit a foreign country for the first time. The study further documented various forms of culture shock such as communication, dress, religion, food, and language etc., and also proposed mechanisms to handle it. The data were collected from 110 respondents through a series of semi-structured interviews with Omani nationals and expatriates currently working in the Sultanate of Oman. The respondents were selected from a wide variety of demographic, socioeconomic and organizational backgrounds to reflect the true multinational workforce structure in Oman. The interviews were conducted by adopting a three-step process. One of the major findings of this research study is that both Omanis and expatriates who travel abroad encountered cultural shock. The study also concluded that most respondents were affected (culture shock) by religious and traditional issues, whereas factors such as individualism vs. collectivism, power distance, rules and weather patterns did not affect them much. This study also documented fourteen different categories of culture shock that can be experienced by people while visiting foreign cultures.
Scanning Electron Microscopy and Energy-Dispersive X-Ray Microanalysis of Set CEM Cement after Application of Different Bleaching Agents

Introduction: The present study evaluated the element distribution in completely set calcium-enriched mixture (CEM) cement after application of 35% carbamide peroxide, 40% hydrogen peroxide and sodium perborate as commercial bleaching agents using an energy-dispersive x-ray microanalysis (EDX) system. The surface structure was also observed using the scanning electron microscope (SEM). Methods and Materials: Twenty completely set CEM cement samples, measuring 4×4 mm2, were prepared in the present in vitro study and randomly divided into 4 groups based on the preparation technique as follows: the control group; 35% carbamide peroxide group in contact for 30-60 min for 4 times; 40% hydrogen peroxide group with contact time of 15-20 min for 3 times; and sodium perborate group, where the powder and liquid were mixed and placed on CEM cement surface 4 times. Data were analyzed at a significance level of 0.05 through the one Way ANOVA and Tukey’s post hoc tests. Results: EDX showed similar element distribution of oxygen, sodium, calcium and carbon in CEM cement with the use of carbamide peroxide and hydroxide peroxide; however, the distribution of silicon was different (P<0.05). In addition, these bleaching agents resulted in significantly higher levels of oxygen and carbon (P<0.05) and a lower level of calcium (P<0.05) compared to the control group. SEM of the control group showed plate-like and globular structure. Sodium perborate was similar to control group due to its weak oxidizing properties. Globular structures and numerous woodpecker holes were observed on the even surface on the carbamide peroxide group. Conclusion: The mean elemental distribution of completely set CEM cement was different when exposed to sodium perborate, carbamide peroxide and hydrogen peroxide.
Teaching efficacy beliefs of national board certified physical educators

The National Board of Professional Teaching Standards offers a voluntary advanced certification for K-12 teachers. The majority of teachers who pursue this professional development program live in the USA, although there are National Board Certified teachers across the globe. This study examined National Board Certified Physical Education Teachers’ (NBCPETs) teaching efficacy beliefs. In total, 334 NBCPET participants completed a demographic questionnaire and survey that included the Teacher Efficacy Scale. From that group, 65 were randomly selected and interviewed. Participants described perceptions of their abilities to influence learning and perceptions of how their teaching effectiveness compared to non-board certified physical educators. Teacher Efficacy Scale scores of respondents revealed strong Personal Teaching Efficacy (PTE), and their PTE scores were higher than their General Teaching Efficacy scores. Most NBCPETs expressed confidence in their abilities to influence student learning. Emerging themes related to their perceptions about their own teaching success were as follows: differentiated instruction, persistence, connection with and care for students, and work in a content area conducive to influencing students. While comparing their own teaching effectiveness with non-NBCPETs, most participants articulated a propensity to reflect on practice, a deeper understanding of and commitment to teaching effectiveness, and greater motivation to excel.
In Vitro Characterization and Mosquito (Aedes aegypti) Repellent Activity of Essential-Oils-Loaded Nanoemulsions

The nanoemulsions composed of citronella oil, hairy basil oil, and vetiver oil with mean droplet sizes ranging from 150 to 220 nm were prepared and investigated both in vitro and in vivo. Larger emulsion droplets (195–220 nm) shifted toward a smaller size (150–160 nm) after high-pressure homogenization and resulted in higher release rate. We proposed that thin films obtained from the nanoemulsions with smaller droplet size would have higher integrity, thus increasing the vaporization of essential oils and subsequently prolonging the mosquito repellant activity. The release rates were fitted with Avrami’s equations and n values were in the same range of 0.6 to 1.0, implying that the release of encapsulated limonene was controlled by the diffusion mechanism from the emulsion droplet. By using high-pressure homogenization together with optimum concentrations of 5% (w/w) hairy basil oil, 5% (w/w) vetiver oil (5%), and 10% (w/w) citronella oil could improve physical stability and prolong mosquito protection time to 4.7 h due to the combination of these three essential oils as well as small droplet size of nanoemulsion.
Comparison of tibolone and 17beta-estradiol administration on the expression of zonula occludens-1, occludin, glial fibrillary acidic protein and c-fos levels in the brain cortex and hippocampus of female rats.

OBJECTIVES To compare the effect exerted by oral tibolone or intramuscular 17β-estradiol administration on the expression of ZO-1, occludin, GFAP and c-fos levels in the brain cortex and hippocampus of ovariectomized rats. RESULTS Immunostaining for ZO-1 and occludin revealed similar staining patterns between controls and tibolone rats and between controls and E2 rats. When staining in tibolone and E2 rats were compared both for ZO-1 and occludin, staining patterns were again identical. Positive staining for the GFAP was detected in the controls, tibolone rats and E2 rats. Staining was more intense in the tibolone rats than controls and in the E2 rats than controls. In sections from the controls, tibolone rats and E2 rats, number of reactive cells for c-fos were 1.75±0.25, 3.75±0.36 and 4.50±0.50, respectively. There was a statistically significant difference between the three groups (p=0.0001). Comparison of tibolone and E2 rats revealed no statistically significant difference (p=0.246). CONCLUSIONS It is well known that natural hormones like E2 regulate brain development and function. Our results provide further information on the mechanism of action of tibolone in the brain cortex and hippocampus. These results will allow us to continue with further studies with different post-ovariectomy intervals, because tibolone can be proposed as an attractive alternative for hormone replacement therapy, acting as a neuroprotective agent for the prevention of neurodegenerative diseases in menopausal women.
Traffic- and Thermal-aware Adaptive Beltway Routing for three dimensional Network-on-Chip systems

The distribution of traffic and temperature in a high-performance three dimensional Network-on-Chip (3D NoC) system become more unbalanced because of chip stacking and applied minimal routing algorithms. To regulate the temperature under a certain thermal limit, the overheated nodes are usually throttled by run-time thermal management (RTM). Therefore, the network topology becomes a Non-Stationary Irregular Mesh (NSI-Mesh) and leads to heavy traffic congestion around the throttled nodes. Because of the traffic imbalance in the network, the system performance degrades sharply as temperature rises. In this paper, a Traffic- and Thermal-aware Adaptive Beltway Routing (TTABR) is proposed to balance both the distribution of the traffic and temperature in the network. The proposed TTABR can be applied to NSI-Mesh and regular mesh. The experimental results show that the proposed TTABR can achieve more balanced both traffic and temperature distribution, and the network throughput is improved by around 3.4~113% with less than 18% area overhead.
Effects of Topographical and Edaphic Factors on Tree Community Structure and Diversity of Subtropical Mountain Forests in the Lower Lancang River Basin

We investigated community structure and tree species diversity of six subtropical mountain forests in relation to 11 topographical and edaphic factors in Lower Lancang River Basin, Yunnan Province, China, based on a census of all trees with diameter at breast height ≥5 cm in 45 0.06-ha plots. The forests were as follows: a river valley monsoon forest, semi-humid evergreen broad-leaved forest, monsoon evergreen broad-leaved forest, mid-mountain humid evergreen broad-leaved forest, summit mossy dwarf forest, and warm needle-leaved forest. Owing to the variation in microenvironment, forest structure (tree density, mean height, mean diameter at breast height, mean basal area at breast height) and tree diversity indices (the number of species, Margalef richness, Shannon-Wiener diversity, Simpson’s index, and Pielou’s evenness) differed significantly among forest types but did not differ among sites. We recorded a total of 5155 canopy trees belonging to 204 tree species, 104 genera, and 50 families at three sites, and the co-occurrence of tree species between adjacent communities was higher. A clear forest community distribution along an altitudinal gradient suggested that elevation was important in tree species distribution. Ordination identified elevation, slope degree, slope position, soil pH, organic matter, total nitrogen, and available nitrogen as significant explanatory variables of tree species distribution and showed that elevation was more important than the rest of the environmental variables in affecting local woody plant distribution. Understanding relationships between tree species distribution and environmental factors in subtropical mountain forests of the Lower Lancang River Basin would enable us to apply these findings to forest management and vegetation restoration.
Consumer Satisfaction and Repatronage Intentions Following a Business Failure: The Importance of Perceived Control with an Organizational Complaint

The purpose of this study was to examine consumers' perceptions of control regarding complaints to organizations. Participants were 134 people recruited to write genuine letters of complaint to organizations that had recently failed them. Consumers' perceptions of their communicative control were examined as they related to satisfaction with organizational recovery efforts and intent to do business with organizations in the future. Results indicated that providing evidence that a person made an impact on an organization through his or her complaint led to increased satisfaction with an organizational response and higher intent to do business with an organization in the future.
Gender and regional differences in risk perception: results from implementing the Seveso II Directive in Sweden

This paper attempts to investigate whether there are gender and regional specific differences in risk perception in three municipalities in Sweden. It focuses on differences between gender and region with regard to risk perception, issues of trust and credibility as well as attitudes towards local industry and emergency response behaviour. This study is based on results from a larger study investigating the Seveso II Directive in Sweden. The aim of this paper is to investigate how gender and regional differences appear and in what way they should be taken into consideration when it comes to implementing national laws that deal with information to the public. The results show that there are differences between gender consistent with earlier findings, and also that there are regional differences which may influence the risk communication effort. Men tend to report having more knowledge of the industrial activities in their community and estimate the possible effect of an accident to be smaller than do women. Regional comparisons show that there are local variations with regard to estimated knowledge and the credibility of a source. Attempts are made to explain the gender differences from a power/influence perspective, and attribute the local variations to specific cultural contexts.
Influence of beclomethasone and salmeterol on the perception of methacholine-induced bronchoconstriction.

BACKGROUND Patient evaluation of asthma severity and medication needs is mostly based on respiratory symptoms and may be influenced by changes in perception of bronchoconstriction-induced sensations. However, the influence of asthma medication on the ability to perceive symptoms is still to be documented. This study evaluated the effects of short-term and regular use of salmeterol on the perception of methacholine-induced bronchoconstriction (MIB) in subjects with mild asthma, using inhaled salbutamol on an "as required" basis (n=15), and in subjects with moderate asthma, using daily inhaled beclomethasone (mean daily dose, 640 microg; n=15) in addition to salbutamol to control their asthma. METHODS Methacholine challenges (MC) were performed at entry into the study, and then before, 1, and 12 h following inhalation of 50 microg of salmeterol or a placebo, after a 15-day baseline period; and after 4 weeks of twice daily use of those treatments. The measurements were then repeated with the alternate treatment after a 15-day washout period. Finally, a last MC was performed after another 15-day washout period. For each MC, the perception score of bronchoconstriction-associated breathlessness at 20% fall in FEV1 (PS20) was evaluated on a modified Borg scale from 0 to 10. RESULTS Subjects using regular beclomethasone had a higher baseline PS20 than those using only salbutamol (means: 3.06 0.06 and 2.01+/-0.07, p=0.0001). Short- and long-term use of salmeterol did not change significantly the PS20 compared with placebo (p>0.05) in either group (with or without corticosteroid). Although there were some intraindividual variations, mean PS20 did not vary significantly throughout the study. CONCLUSION These observations show that the perception of bronchoconstriction-associated breathlessness is not influenced by regular use of salmeterol. Patients using inhaled corticosteroids show a greater perception of MIB.
The Statistical Inevitability of Stability‐Diversity Relationships in Community Ecology

In this article, we explain an often overlooked process that may significantly contribute to positive correlations between measures of species diversity and community stability. Empirical studies showing positive stability‐diversity relationships have, for the most part, used a single class of stability (or, more accurately, instability) measures: the temporal variation in aggregate community properties such as biomass or productivity. We show that for these measures, stability will essentially always rise with species diversity because of the statistical averaging of the fluctuations in species' abundances. This simple probabilistic process will operate in the absence of any strong species interactions, although its strength is driven by the relative abundances of species, as well as by the existence of positive or negative correlations in the fluctuations of species. To explore the possible importance of this effect in real communities, we fit a simple simulation model to Tilman's grassland community. Our results indicate that statistical averaging might play a substantial role in explaining stability‐diversity correlations for this and other systems. Models of statistical averaging can serve as a useful baseline for predictions of community stability, to which the influences of both negative and positive species interactions may then be added and tested.
Hepatobiliary fascioliasis: sonographic and CT findings in 87 patients during the initial phase and long-term follow-up.

OBJECTIVE The purpose of our study was to describe the initial and long-term imaging findings in hepatobiliary fascioliasis. CONCLUSION Most patients with fascioliasis have typical hepatobiliary imaging findings. It is important to know that residual fibrotic or necrotic foci may remain for years after cure. Long-term complications are rare in fascioliasis, and malignancy or cirrhosis related to the disease has not been observed.
