Competing for attention: The effects of jealousy on preference for attention‐grabbing products
Authors: Huang Xun (Irene) , Dong Ping , Wyer Robert S. 
Published: January 2017

AbstractJealous individuals often harbor feelings of aggression toward both their relationship partner and their rivals. However, jealousy can also have quite different effects that have implications for people's product preferences. Five experiments converge on the conclusion that jealousy induces a desire to recapture attention from one's partner and that this desire generalizes to unrelated situations in which the partner is not involved. Thus, jealousy increases people's preferences for attention‐grabbing products and this is true even when the public display of the products could bring negative attention. The effect of jealousy only occurs when the products are consumed in public. Finally, the influence of jealousy on product evaluations is distinguished from that of other negative emotions such as envy and feelings of powerlessness.

Authors: Salman Michael S. , Klassen Samantha F. , Johnston Janine L. 
Published: January 2017

AbstractBackground: Recurrent ataxia is encountered infrequently in clinical pediatric neurology practise and presents with diagnostic challenges. It is caused by several disorders. Our aims were to describe the epidemiology and clinical features in children with recurrent ataxia. Materials and Methods: A retrospective review was undertaken in 185 children with chronic ataxia, who presented during 1991 to 2008. Several databases were searched to ensure optimum ascertainment. Patients with brain tumors or isolated disorders of the peripheral nerves or vestibular system were excluded. Results: Recurrent ataxia was reported in 21 patients. Their age range was between 6 and 32.75 years (males=12). The crude period prevalence rate for the 18-year study period was 7.44/100,000. Eight patients had episodic ataxia and seven had inflammatory and metabolic disorders. In the rest the etiology was unknown. Many patients presented with ataxia, dizziness, and vertigo. The frequency and duration of the ataxic episodes varied from several per day to one every few months. Other clinical features included developmental delay and seizures. Neuroimaging in episodic ataxia was normal and abnormal in inflammatory or metabolic disorders. Acetazolamide provided symptomatic relief in patients with episodic ataxia, while steroids were beneficial in patients with an inflammatory etiology. One child with a metabolic disorder died. Conclusions: Recurrent ataxia is an uncommon presentation in children and mortality is rare. Genetic, metabolic, and inflammatory disorders should be considered in these patients. Neuroimaging is essential. Acetazolamide in selected patients provides good symptomatic relief.
On the Global Gaussian Lipschitz Space
Authors: Liu Liguang , Sjögren Peter 
Published: January 2017

AbstractIt is well known that the standard Lipschitz space in Euclidean space, with exponent α ∈ (0, 1), can be characterized by means of the inequality , where is the Poisson integral of the function f. There are two cases: one can either assume that the functions in the space are bounded, or one can not make such an assumption. In the setting of the Ornstein–Uhlenbeck semigroup in ℝn, Gatto and Urbina defined a Lipschitz space by means of a similar inequality for the Ornstein–Uhlenbeck Poisson integral, considering bounded functions. In a preceding paper, the authors characterized that space by means of a Lipschitz-type continuity condition. The present paper defines a Lipschitz space in the same setting in a similar way, but now without the boundedness condition. Our main result says that this space can also be described by a continuity condition. The functions in this space turn out to have at most logarithmic growth at infinity.
Magic in Historical Theory and Practice
Authors: MAXWELL-STUART P. G. 
Published: January 2017

Collected essays are a popular and useful way of throwing light on their proclaimed subject matter or period, and of bringing recent research to a more general audience. They are, of course, inevitably limited in their scope, although this does not necessarily imply that they are at all parochial. ‘Europe’ is a frequent and obvious geographical limitation imposed upon matter dealing with magic and witchcraft, and ‘early modern’ a common chronological set of termini. Thus, the recent Oxford handbook of witchcraft (2013) declares itself confined – a very broad confinement – to early modern Europe and Colonial America. Bengt Ankarloo and Stuart Clark's earlier Athlone history of witchcraft and magic in Europe (1999–2002) again takes Europe as its principal theatre, although its spread over six volumes allows the editors to begin with the ancient Middle East and extend chronologically to the twentieth century. By adding ‘in the West’ to the title of his collection, Collins therefore appears to be confining himself geographically (although ‘the West’ is remarkably large), while ‘from antiquity to the present’ extends to his contributors a brave allowance of time in a single volume. This volume, then, more or less follows an established pattern for this kind of scholarly work. How far does it succeed in matching the endeavours and achievements of its predecessors?
Reducing Political Bias in Political Science Estimates
Authors: Zigerell L. J. 
Published: January 2017

ABSTRACTPolitical science researchers have flexibility in how to analyze data, how to report data, and whether to report on data. A review of examples of reporting flexibility from the race and sex discrimination literature illustrates how research design choices can influence estimates and inferences. This reporting flexibility—coupled with the political imbalance among political scientists—creates the potential for political bias in reported political science estimates. These biases can be reduced or eliminated through preregistration and preacceptance, with researchers committing to a research design before completing data collection. Removing the potential for reporting flexibility can raise the credibility of political science research.
Assessing Undergraduate Student Learning in Political Science: Development and Implementation of the “PACKS” Survey
Authors: Sydnor Emily , Pankiewicz Nicole 
Published: January 2017

ABSTRACT
This article describes the creation and implementation of a new online assessment program (“PACKS”) for the department of politics at the University of Virginia. It discusses the benefits of online assessments, including the ease of administration, minimal faculty involvement, ability to link assessment data to existing student data (e.g., GPA and courses completed), and ability to track student progress over time. The assessment can be easily adapted for use by other departments in the social sciences and by other colleges and universities. The authors discuss the drawbacks to this type of assessment, including the challenge of obtaining the highest number of respondents. They recommend using a strong incentive to ensure full participation, such as an advising hold that prevents students from registering until they complete the assessment. The authors contend that implementing survey-based assessment tools is an ideal way for departments to meet their accrediting institutions’ assessment requirements.
SUDDEN VERSUS SLOW DEATH OF CITIES
Authors: Downey Davia C. , Reese Laura A. 
Published: January 2017

AbstractThis paper constitutes a follow-up to an argument made during the late fall of 2005 that posited that many of the approaches and responses to sudden natural disasters might be effectively applied to areas experiencing more chronic economic decay. Using census, budgetary, and political data, including an analysis of planning and development documents, the paper addresses the following research questions:•What were the economic and social trajectories of Detroit and New Orleans prior to their respective disasters?•How did the responses to the hurricane impact New Orleans?•Despite the attention given to New Orleans, why do current conditions differ little from Detroit?The findings suggest that Detroit and New Orleans were clearly both highly distressed cities, with large minority populations and significant inequality prior to Katrina, although Detroit’s situation was arguably more severe. Significant media attention and investment in New Orleans appeared to follow in the wake of the hurricane. However, looking at federal and state investment in context suggests that it was not as high as might have been expected and implementation delays may well have lessened its impact. It is not at all clear that the response in New Orleans changed its economic trajectory much beyond that of Detroit, suggesting that the response to sudden disaster might not have aided the slow death of Detroit.

SummaryAn exploratory survey to phenotypically characterize indigenous chicken populations was carried out in Metekel zone of Northwestern Ethiopia in April 2013. A total of 69 males and 244 females were sampled to record their qualitative and quantitative traits. Eight quantitative and 16 qualitative variables were measured. Sampling included three districts representing different agroecological zones. Coefficient of variation for quantitative variables ranged from 6.38 to 52.37 percent in male sample populations and 4.59–21.4 percent in females. The chi-square tests for plumage colour of the neck, ear lobe colour and skeletal variant type were highly significant (χ2&lt; 0.05). The correct classification percentage from discriminant analysis was 93.73 and 98.41 percent for male and female sample populations, respectively, indicating the homogeneity of the chicken populations within districts. The stepwise discriminant analysis identified five variables for male and three variables for female sample populations, which had the highest discriminating power. Canonical analyses showed that differences in body measurements between indigenous chicken populations were highly significant (P &lt;0.0001). The results obtained from on-farm performance evaluation indicated that the average age at first lay of hens, number of chicks weaned and mean number of eggs laid per bird per year were 5.5 months, 6.5, 50.1, respectively. This information will constitute the basis for further characterization and development of conservation strategies for indigenous chicken populations of Northwestern Ethiopia.

Published: January 2017

SummaryDevelopment of the livestock industry and its role in poverty alleviation in developing countries depends on how adaptive the production systems are to changing global environmental and economic trends. This paper characterizes dairy production systems in India, Tanzania, Kenya and Nicaragua, and describes the genetic and breeding technologies that hold promise for the advancement of global development goals. The dairy value chain has been prioritized for development under the CGIAR research programme on Livestock and Fish in Tanzania (East Africa), India (South Asia) and Nicaragua (Latin America), while ILRI is involved in research on dairy development in Kenya. In all the countries, a large number of smallholder farmers operating mixed crop–livestock production systems play a significant role in dairy production. In Tanzania, Kenya and Nicaragua, milk is predominantly produced by cattle of genotypes that differ both across countries and among production systems within the same country. In India, buffaloes contribute to a larger proportion of the national milk than cattle. Information on productivity per animal and on optimal genotypes to utilize within the smallholder production systems of all the countries is however limited. Crossbreeding and artificial insemination were identified as the most widely utilized breeding and reproductive technologies. Only in Kenya is there a national organization conducting livestock recording and monitoring productivity, however, the proportion of the dairy cattle population enrolled in the recording system is small (&lt;2.5 percent). In all the countries, enhanced and adequately planned use of breeding and reproductive technologies, complemented with the relevant infrastructure, is needed to sustainably increase dairy productivity. The capacities of actors in the dairy value chain need to be developed in order to properly implement and manage improvements.

SummaryGoats make up the largest group of ruminant livestock in Nigeria and are strategic in bridging animal protein supply gap and improving the economy of rural households. The hypervariable region 1 (HVR1) of the caprine mitochondrial genome was investigated to better understand genetic diversity important for improving selection for animal breeding and conservation programs. We sequenced and analysed the mitochondrial DNA (mtDNA) HVR1 in 291 unrelated indigenous Nigerian goats (West African Dwarf (WAD), Red Sokoto (RSO) and Sahel (SAH)), randomly sampled from around the country, and compared them with the HVR1 sequences of 336 Indian goats and 12 other sequences in five different species in the genusCapra(C. falconeri, C. ibex nubiana, C. aegagrus, C. cylindricornisandC. sibirica). A total of 139 polymorphic sites from 291 individuals were captured in 204 haplotypes. Within and among population variations were 77.25 and 22.74 percent, respectively. Nigerian goats showed high genetic diversity (0.87) and high FST values, and separate from Indian goats and other wild species. Haplogroups in WAD separates it from RSO and SAH concomitant with a different demographic history. Clear genetic structure was found among Nigerian goat breeds with appreciable variation in mtDNA HVR1 region. This study grouped Nigerian goat breeds into two major groups suggesting two different demographic origins for Northern and Southern breeds. High genetic admixing denotes different maternal origins and in contrast to evidence from goats from Levant and Central Asia, where goats were originally domesticated.

Published: January 2017

SummaryThe goal of this study was to characterize the Hamra goat population and to determine if Hamra goats of Beni Arouss and Rommani regions belong to the same population. Eleven morphometric traits of 157 Hamra animals (94 from Beni Arouss and 63 from Rommani) were used for this study. Overall, heart girth, body length, height at withers (HaW), height at rump (HS), chest depth (ChD), pelvis width (PW), chest width (CW), cannon circumference, head length (HeL), head width (HeW) and horn length (HL) of Hamra goats averaged 81.3, 61.5, 64.8, 65.3, 40.9, 19.3, 20.2, 9.67, 28.0, 26.3 and 23.4 cm, respectively. The effect of region was significant only on HaW, PW, HeL, HeW and HL, indicating certain homogeneity among goats of the two regions. Moreover, the inter region variance component ranged from 0 percent (absence of variability) for HS, CW, ChD and ChD to 18.5 percent for HeL, suggesting that the variability of body measurements between Beni Arouss and Rommani regions is very low. The factor analysis revealed four factors, which accounted for 73.5 percent of the total variance. The most discriminant variables between the two populations were HeL, HeW, PW and CW. The Mahalanobis distance between the two populations was 1.197, suggesting that there was genetic exchange between the two populations. The discriminant analysis showed that 80.9 percent of Rommani and 50.0 percent of Beni Arouss individuals were classified into their respective population. Results obtained will help in developing improvement and preservation strategies for the Hamra goat population.

SummaryThe study was aimed to identify, characterize and describe the phenotypic variation of indigenous goose populations in Bangladesh. The research was conducted at Sylhet Sadar Upazilla in Sylhet district and encompassed about 141 geese (74 brown type and 67 white type). Least Square Mean ± SE of body length, wing span, shank length, beak length and head length of mature indigenous goose were 73.47 ± 0.95, 134.53 ± 1.38, 9.27 ± 0.09, 8.88 ± 0.10 and 6.42 ± 0.02 cm, respectively. Males were significantly (p&lt; 0.01) higher than their female counterparts for all morphometric traits but no significant differences (p&gt; 0.05) were found between two types. The body weight of indigenous goose at day old, 2-week, 1-month, 2-month and 10-month of age were 95.45 ± 0.88, 148.59 ± 1.55, 407.34 ± 7.27 gm, 1.19 ± 0.03 kg and 3.65 ± 0.06 kg, respectively. Males were significantly (p&lt; 0.01) heavier than females in all age groups except day old gosling but no significant difference (p&gt; 0.05) were observed for body weights between two types of goose. Egg weight, egg length, egg width, incubation period, clutch size, number of eggs in a breeding season and age at first egg were 131.85 ± 1.70 gm, 7.40 ± 0.02 cm, 5.22 ± 0.02 cm, 30.30 ± 0.07 days, 7.42 ± 0.08, 20.52 ± 0.38 and 313.22 ± 3.03 days, respectively. The number of eggs in a breeding season of brown type were significantly (p&lt; 0.05) higher than that of white type goose. This study provides a bench mark for the morphometric traits and performance of goose in Bangladesh.
Redox potential as a master variable controlling pathways of metal reduction by Geobacter sulfurreducens
Authors: Levar Caleb E , Hoffman Colleen L , Dunshee Aubrey J , Toner Brandy M , Bond Daniel R 
Published: January 2017

Abstract
Geobacter sulfurreducens uses at least two different pathways to transport electrons out of the inner membrane quinone pool before reducing acceptors beyond the outer membrane. When growing on electrodes poised at oxidizing potentials, the CbcL-dependent pathway operates at or below redox potentials of –0.10 V vs the standard hydrogen electrode, whereas the ImcH-dependent pathway operates only above this value. Here, we provide evidence that G. sulfurreducens also requires different electron transfer proteins for reduction of a wide range of Fe(III)- and Mn(IV)-(oxyhydr)oxides, and must transition from a high- to low-potential pathway during reduction of commonly studied soluble and insoluble metal electron acceptors. Freshly precipitated Fe(III)-(oxyhydr)oxides could not be reduced by mutants lacking the high-potential pathway. Aging these minerals by autoclaving did not change their powder X-ray diffraction pattern, but restored reduction by mutants lacking the high-potential pathway. Mutants lacking the low-potential, CbcL-dependent pathway had higher growth yields with both soluble and insoluble Fe(III). Together, these data suggest that the ImcH-dependent pathway exists to harvest additional energy when conditions permit, and CbcL switches on to allow respiration closer to thermodynamic equilibrium conditions. With evidence of multiple pathways within a single organism, the study of extracellular respiration should consider not only the crystal structure or solubility of a mineral electron acceptor, but rather the redox potential, as this variable determines the energetic reward affecting reduction rates, extents, and final microbial growth yields in the environment.
Patterns of bacterial diversity in the marine planktonic particulate matter continuum

Published: January 2017

Abstract
Depending on their relationship with the pelagic particulate matter, planktonic prokaryotes have traditionally been classified into two types of communities: free-living (FL) or attached (ATT) to particles, and are generally separated using only one pore-size filter in a differential filtration. Nonetheless, particulate matter in the oceans appears in a continuum of sizes. Here we separated this continuum into six discrete size-fractions, from 0.2 to 200 μm, and described the prokaryotes associated to each of them. Each size-fraction presented different bacterial communities, with a range of 23–42% of unique (OTUs) in each size-fraction, supporting the idea that they contained distinct types of particles. An increase in richness was observed from the smallest to the largest size-fractions, suggesting that increasingly larger particles contributed new niches. Our results show that a multiple size-fractionation provides a more exhaustive description of the bacterial diversity and community structure than the use of only one filter. In addition, and based on our results, we propose an alternative to the dichotomy of FL or ATT lifestyles, in which we differentiate the taxonomic groups with preference for the smaller fractions, those that do not show preferences for small or large fractions, and those that preferentially appear in larger fractions.

AbstractStem cell therapy represents a promising strategy in regenerative medicine. However, cells need to be carefully preserved and processed before usage. In addition, cell transplantation carries immunogenicity and/or tumourigenicity risks. Mounting lines of evidence indicate that stem cells exert their beneficial effects mainly through secretion (of regenerative factors) and membrane-based cell–cell interaction with the injured cells. Here, we fabricate a synthetic cell-mimicking microparticle (CMMP) that recapitulates stem cell functions in tissue repair. CMMPs carry similar secreted proteins and membranes as genuine cardiac stem cells do. In a mouse model of myocardial infarction, injection of CMMPs leads to the preservation of viable myocardium and augmentation of cardiac functions similar to cardiac stem cell therapy. CMMPs (derived from human cells) do not stimulate T-cell infiltration in immuno-competent mice. In conclusion, CMMPs act as ‘synthetic stem cells’ which mimic the paracrine and biointerfacing activities of natural stem cells in therapeutic cardiac regeneration.
