The influence of occupational communities on buyer behavior

In this paper, we proposed a broader conceptualization of buyer behavior that takes into consideration the role occupational communities and cultures play in the interpretation of industrial marketers’ communications and in the formation of opinions about products, suppliers and solutions. From a theoretical point of view, our paper is grounded in the literature on occupational communities – which is an influential research stream within social sciences, organization studies and industrial relations – and in consumer culture theory – which has highlighted the relevance for marketing theory and practice of variously defined communities of consumers. Methodologically, this paper proposes the adoption of interpretive methods that require researcher field-work and socialization into the occupational community to be investigated. On the managerial side, we show that key marketing decisions, including segmentation, positioning and targeting, may be improved when adopting an occupational community theoretical perspective.
Combined Impact of Acute Exposure to Ammonia and Temperature Stress on the Freshwater Mussel Unio pictorum

Nitrogen compounds, particularly ammonia, and temperature are suspected major stressors for aquatic organisms, but little is known about their impact on globally declining freshwater mussels (Unionoida). In this study, we tested the combined effects of ammonia and temperature stress on painter’s mussel (Unio pictorum) survival, filtration behavior, hemocyte abundance, hemocyte mortality and glycogen energy status, at concentrations ranging from 0.3 to 9.0 mg·L−1 total ammonia nitrogen (NH4-N) in 96 h acute exposures at two temperatures, 17 °C and 25 °C and a pH of 8.8. The results indicate a low sensitivity of U. pictorum to elevated ammonia concentrations after short-term exposure, although effects on cell morphology were evident and delayed mortality occurred at the highest test concentration. Most pronounced effects were observed for sublethal physiological endpoints due to elevated temperature, but no synergistic effects with ammonia were evident. Temperature increase resulted in significant effects on tissue glycogen, hyalinocyte mortality and clearance rates. Hemocyte mortalities showed a linear dependency on initial mussel activity as measured by their clearance rate. Since the main stressors tested in this study, ammonia and temperature, are predicted to increase in most freshwater ecosystems, their impact on other freshwater mussel species including different life-stages should be comprehensively assessed.
Diurnal and seasonal fish horizontal migrations in the Sulejów reservoir, Poland

Horizontal fish migrations in the Sulejów reservoir were studied acoustically. The SIMRAD EY500 echo sounder was used with transducer looking horizontally at three sites of the reservoir located along its longitudinal axis. Fish began to migrate horizontally in June and stopped in October. The diurnal cycle was very well pronounced, with fish going to open water at night and coming back to littoral in early morning. The timing of migrations was correlated with light conditions; the longer were nights the longer fish stayed off shore. Starting from August, apart from diurnal migrations between pelagial and littoral also some movement of fish towards the upper part of the reservoir was noted. It has been hypothesised that it was caused by unfavourable environmental conditions in the lower part of the reservoir, where the Microicystis aeruginosa bloom was observed, and the oxygen concentrations were much lower than in the upper part. These observations confirm that acoustics provides a good tool for controlling behaviour of fish, that are essential indicators of the water quality.
Effects of a cognitive-behavioral intervention targeting weight stigma: A randomized controlled trial.

OBJECTIVE To test the effects of a cognitive-behavioral intervention for weight bias internalization (WBI; i.e., self-stigma) combined with behavioral weight loss (BWL). METHOD Adults with obesity and elevated WBI were randomly assigned to BWL alone or combined with the Weight Bias Internalization and Stigma Program (BWL + BIAS). Participants attended weekly group meetings for 12 weeks, followed by 2 biweekly and 2 monthly meetings (26 weeks total). Changes at Week 12 on the Weight Bias Internalization Scale (WBIS) and Weight Self-Stigma Questionnaire (WSSQ) were the principal outcomes, with changes at Week 26 assessed as secondary outcomes. Other outcomes included changes in mood, body image, eating behaviors, self-monitoring, and weight. RESULTS Seventy-two participants were randomized (84.7% female, 66.7% Black, mean age = 47.1 ± 11.5 years) Linear mixed models showed no significant differences between the BWL + BIAS and BWL groups in WBIS changes at Week 12 (-1.3 ± 0.2 vs. -1.0 ± 0.2) or week 26 (-1.5 ± 0.2 vs. -1.3 ± 0.2). BWL + BIAS participants had greater reductions in WSSQ total scores at Week 12 (p = .03), with greater changes on the self-devaluation subscale at Weeks 12 and 26 (p ≤ .03). BWL + BIAS participants reported significantly greater benefits on measures of eating and self-monitoring. Percent weight loss at Week 26 did not differ significantly between groups (BWL + BIAS = -4.5 ± 1.0%, BWL = -5.9 ± 1.0%, p = .28). CONCLUSION A psychological intervention for WBI produced short-term reductions in some aspects of weight self-stigma in persons with obesity.

The Role of Annual Flowering Plant Strips on a Melon Crop in Central Spain. Influence on Pollinators and Crop

Planting flower strips adjacent to crops is among the habitat-management practices employed to offer alternative floral resources to pollinators. However, more information is needed to understand their potential spill-over of pollinators on nearby insect-pollinated crops. Over the course of two consecutive years, the suitability of a flower mixture of 10 herbaceous plants for pollinators was evaluated on a weekly basis, in a randomized block design of two melon plots (10 × 10 m2) with or without 1 m-wide flower strips. Floral coverage and pollinator visits to the plant species, as well as pollinator visits and the yield and quality of the crop, were assessed. Additionally, the selected mixture was tested for 1 year in a commercial field in order to ascertain how far the flower strip could influence visitors in the crop. The most suitable species for a flower strip in central Spain based on their attractiveness, floral coverage and staggered blossom were Coriandrum sativum L. , Diplotaxis virgata L. , Borago officinalis L. and Calendula officinalis L. The flower strip can act as either pollinator competitor or facilitator to the crop, depending on their floral coverage and/or the predominant species during the crop bloom period. The concurrence of blooming of the rewarding plant C. officinalis with the melon crop should be avoided in our area. In the commercial field, the bee visitation rate in the melon flowers decreased with the distance to the flower strip. No influence of the specific flower strip evaluated on crop productivity or quality was found.
Genetic Landscape of Nonobstructive Azoospermia and New Perspectives for the Clinic

Nonobstructive azoospermia (NOA) represents the most severe expression of male infertility, involving around 1% of the male population and 10% of infertile men. This condition is characterised by the inability of the testis to produce sperm cells, and it is considered to have an important genetic component. During the last two decades, different genetic anomalies, including microdeletions of the Y chromosome, karyotype defects, and missense mutations in genes involved in the reproductive function, have been described as the primary cause of NOA in many infertile men. However, these alterations only explain around 25% of azoospermic cases, with the remaining patients showing an idiopathic origin. Recent studies clearly suggest that the so-called idiopathic NOA has a complex aetiology with a polygenic inheritance, which may alter the spermatogenic process. Although we are far from a complete understanding of the molecular mechanisms underlying NOA, the use of the new technologies for genetic analysis has enabled a considerable increase in knowledge during the last years. In this review, we will provide a comprehensive and updated overview of the genetic basis of NOA, with a special focus on the possible application of the recent insights in clinical practice.
Video on Mobile Phones as an Effective Way to Promote Sustainable Practices by Facilitating Innovation Uptake in Mali

A challenge for researchers and other developers of new technologies in agriculture is to find ways of communicating their results and recommendations. This challenge is particularly acute in regions in which farmers have limited access to education and where illiteracy is widespread, such as in the rural areas of Mali. One approach that shows potential, yet remains largely unused by extension services, is the dissemination of educational videos on mobile phones with video and Bluetooth technology (3G mobile phones). It has been shown that the conditions are suitable for this approach to be used in Mali, with 3G mobile phones widely available in the region but there is little empirical evidence of its acceptance and potential impact. This article aims to explore the potential of video on mobile phones as a tool to facilitate the diffusion of new agricultural technologies in Western Africa. Three videos showing agricultural innovations for sustainable production were shown and shared with 200 farmers in twelve villages in Mali. The villages were revisited 10 months later and farmers were asked about their experiences with the videos that had been shared and their previous knowledge of the innovations shown in them. Of the farmers who had watched one of the videos (N=148), 60.1% had adopted at least one of the videos’ innovations. Mobile-phone videos could be accessed by people who had previously received limited access to information sources, such as younger women, and video based information was found to be understandable for illiterate farmers. These results show that mobile-phone videos could enhance information transfer and thereby expand outreach. The use of video on mobile phones is a novel approach to farmer-to-farmer exchange and has tremendous potential for enhancing dissemination programs or specific research and development projects to enable more resilient, inclusive and democratic systems.
Optimization of Shortest-Path Search on RDBMS-Based Graphs

Calculation of the shortest path between two nodes in a graph is a popular operation used in graph queries in applications such as map information systems, social networking services, and biotechnology. Recent shortest-path search techniques based on graphs stored in relational databases are able to calculate the shortest path efficiently, even in large data using frontier-expand-merge operations. However, previous approaches used a sequential bidirectional search method that causes a bottleneck, thus degrading performance. The repeated use of an aggregate SQL function also degrades performance. This paper proposes a parallel bi-directional search method using multithreading. In addition, an efficient optimization method is proposed that uses B-tree indexing instead of an aggregate SQL function. Various experiments using synthetic and real data reveal that the proposed optimization technique performs more efficiently than conventional methods. As the size of data in practical applications continues to grow, these optimizations will enable the shortest path in a graph to be found quickly and accurately.
Genomic Analysis of Mycobacterium tuberculosis Isolates and Construction of a Beijing Lineage Reference Genome

Abstract Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis, kills over 1 million people worldwide annually. Development of drug resistance (DR) in the pathogen is a major challenge for TB control. We conducted whole-genome analysis of seven Taiwan M. tuberculosis isolates: One drug susceptible (DS) and five DR Beijing lineage isolates and one DR Euro-American lineage isolate. Developing a new method for DR mutation identification and applying it to the next-generation sequencing (NGS) data from the 6 Beijing lineage isolates, we identified 13 known and 6 candidate DR mutations and provided experimental support for 4 of them. We assembled the genomes of one DS and two DR Beijing lineage isolates and the Euro-American lineage isolate using NGS data. Moreover, using both PacBio and NGS sequencing data, we obtained a high-quality assembly of an extensive DR Beijing lineage isolate. Comparative analysis of these five newly assembled genomes and two published complete genomes revealed a large number of genetic changes, including gene gains and losses, indels and translocations, suggesting rapid evolution of M. tuberculosis. We found the MazEF toxin–antitoxin system in all the seven isolates studied and several interesting mutations in MazEF proteins. Finally, we used the four assembled Beijing lineage genomes to construct a high-quality Beijing lineage reference genome that is DS and contains all the genes in the four genomes. It contains 212 genes not found in the standard reference H37Rv, which is Euro-American. It is therefore a better reference than H37Rv for the Beijing lineage, the predominant lineage in Asia.
Exploring Lexical-Semantic Knowledge in the Generation of Novel Riddles in Portuguese

We describe an effort towards the automatic generation of novel riddles in Portuguese, ultimately with humour value. Riddle generation ﬁts in the common architecture of a NLG system and may follow different models, described here, all based on features of a concept, acquired from a lexical-semantic knowledge base. Generated riddles were manually assessed by humans, who rated them as fairly interpretable, surprising, and novel, even if with low humour potential.
Concrete Preliminary Damage Inspection by Classification of Terrestrial Laser Scanner Point Clouds through Systematic Threshold Definition

This paper presents a novel approach for automatic, preliminary detection of damage in concrete structures using ground-based terrestrial laser scanners. The method is based on computation of defect-sensitive features such as the surface curvature, since the surface roughness changes strongly if an area is affected by damage. A robust version of principal component analysis (PCA) classification is proposed to distinguish between structural damage and outliers present in the laser scanning data. Numerical simulations were conducted to develop a systematic point-wise defect classifier that automatically diagnoses the location of superficial damage on the investigated region. The method provides a complete picture of the surface health of concrete structures. It has been tested on two real datasets: a concrete heritage aqueduct in Brooks, Alberta, Canada; and a civil pedestrian concrete structure. The experiment results demonstrate the validity and accuracy of the proposed systematic framework for detecting and localizing areas of damage as small as 1 cm or less.
Modeling the distribution and seasonality of Neogloboquadrina pachyderma in the North Atlantic Ocean during Heinrich Stadial 1

Fossil shells of planktonic foraminifera serve as the prime source of information on past changes in surface ocean conditions. Because the population size of planktonic foraminifera species changes throughout the year, the signal preserved in fossil shells is biased toward the conditions when species production was at its maximum. The amplitude of the potential seasonal bias is a function of the magnitude of the seasonal cycle in production. Here we use a planktonic foraminifera model coupled to an ecosystem model to investigate to what degree seasonal variations in production of the species Neogloboquadrina pachyderma may affect paleoceanographic reconstructions during Heinrich Stadial 1 (∼ 18–15 cal ka B.P.) in the North Atlantic Ocean. The model implies that during Heinrich Stadial 1 the maximum seasonal production occurred later in the year compared to the Last Glacial Maximum (∼ 21–19 cal ka B.P.) and the preindustrial era north of 30∘N. A diagnosis of the model output indicates that this change reflects the sensitivity of the species to the seasonal cycle of sea ice cover and food supply, which collectively lead to shifts in the modeled maximum production from the Last Glacial Maximum to Heinrich Stadial 1 by up to 6 months. Assuming equilibrium oxygen isotopic incorporation in the shells of N. pachyderma, the modeled changes in seasonality would result in an underestimation of the actual magnitude of the meltwater isotopic signal recorded by fossil assemblages of N. pachyderma wherever calcification is likely to take place.
Molecular Evolution of the Glutathione S-Transferase Family in the Bemisia tabaci Species Complex

Abstract The glutathione S-transferase (GST) family plays an important role in the adaptation of herbivorous insects to new host plants and other environmental constrains. The family codes for enzymes that neutralize reactive oxygen species and phytotoxins through the conjugation of reduced glutathione. Here, we studied the molecular evolution of the GST family in Bemisia tabaci, a complex of >35 sibling species, differing in their geographic and host ranges. We tested if some enzymes evolved different functionality, by comparing their sequences in six species, representing five of the six major genetic clades in the complex. Comparisons of the nonsynonymous to synonymous substitution ratios detected positive selection events in 11 codons of 5 cytosolic GSTs. Ten of them are located in the periphery of the GST dimer, suggesting a putative involvement in interactions with other proteins. Modeling the tertiary structure of orthologous enzymes, identified additional 19 mutations in 9 GSTs, likely affecting the enzymes’ functionality. Most of the mutation events were found in the environmentally responsive classes Delta and Sigma, indicating a slightly different delta/sigma tool box in each species. At a broader genomic perspective, our analyses indicated a significant expansion of the Delta GST class in B. tabaci and a general association between the diet breadth of hemipteran species and their total number of GST genes. We raise the possibility that at least some of the identified changes improve the fitness of the B. tabaci species carrying them, leading to their better adaptation to specific environments.
Grazing the Commons: Global Carbon Emissions Forever?

This paper presents the results from our investigation of the per-capita, long- term relation between carbon dioxide emissions and gross domestic product (GDP) for the world, obtained with the use of a new, exible estimator. Consistent with simple economic growth models, we find that regional, population-weighted per- capita emissions systematically increase with income (scale effect) and usually de- cline over time (composition and technology effect). Both our in-sample results and out-of-sample scenarios indicate that this negative time effect is unlikely to compen- sate for the upward-income effect at a global level, in the near future. In particular, even if China's specialization in carbon-intensive industrial sectors would come to a halt, recent trends outside China make a reversal of the overall global trend very unlikely.
Net hepatic release of glucose from precursor supply in ruminants: a meta-analysis

For their glucose supply, ruminants are highly dependent on the endogenous synthesis in the liver, but despite the numerous studies that evaluated hepatic glucose production, very few simultaneously measured hepatic glucose production and uptake of all precursors. As a result, the variability of precursor conversion into glucose in the liver is not known. The present study aimed at investigating by meta-analysis the relationships between hepatic glucose net release and uptake of precursors. We used the FLuxes of nutrients across Organs and tissues in Ruminant Animals database, which gathers international results on net nutrient fluxes at splanchnic level measured in catheterized animals. Response equations were developed for intakes up to 41 g DM intake/kg BW per day of diets varying from 0 to 100 g of concentrate/100 g DM in the absence of additives. The net hepatic uptake of propionate, α-amino-N and l-lactate was linearly and better related to their net portal appearance (NPA) than to their afferent hepatic flux. Blood flow data were corrected for lack of deacetylation of the para-aminohippuric acid, and this correction was shown to impact the response equations. To develop response equations between the availability of precursors (portal appearance and hepatic uptake) and net glucose hepatic release, missing data on precursor fluxes were predicted from dietary characteristics using previously developed response equations. Net hepatic release of glucose was curvilinearly related to hepatic supply and uptake of the sum of precursors, suggesting a lower conversion rate of precursors at high precursor supply. Factors of variation were explored for the linear portion of this relationship, which applied to NPA of precursors ranging from 0.99 to 9.60 mmol C/kg BW per h. Hepatic release of glucose was shown to be reduced by the portal absorption of glucose from diets containing bypass starch and to be increased by an increased uptake of β-hydroxybutyrate indicative of higher body tissue mobilization. These relationships were affected by the physiological status of the animals. In conclusion, we established equations that quantify the net release of glucose by the liver from the net availability of precursors. They provide a quantitative overview of factors regulating hepatic glucose synthesis in ruminants. These equations can be linked with the predictions of portal absorption of nutrients from intake and dietary characteristics, and provide indications of glucose synthesis from dietary characteristics.
S EARCHING FOR LOCAL CONTACT CONSTRAINTS BY THE QUASI-NEWTON METHODS IN THE FINITE ELEMENT PROCEDURES FOR CONTACT-IMPACT PROBLEMS

The essential part of the solution of a contact problem in the finite element method is to locate probable contact areas reliably and efficiently. Most contact searching algorithms are based on the definition of master and slave contact surfaces, when the slave nodes/integration points are checked on against master segments for penetration. The present paper deals with the local search problem which comprises the calculation of the exact position of the slave node/integration point with respect to a given master segment. Since the analytical solution for finding the distance does not exist for a general quadrilateral contact segment, the itera- tive numerical procedure is solved. Several methods for the solution of non-linear algebraic systems are tested: the Newton-Raphson procedure, the least square projection, the steepest descent method, Broydens method, BFGS method, DFP method and the simplex method. The effectiveness of methods is tested by means of a contact-impact problem of two colliding thick plates, for which analytical solution is available.
