Sexual Dimorphism in Stature (SDS), jealousy and mate retention

Previous research has investigated the manner in which absolute height impacts on jealousy and mate retention. Although relative height is also important, little information exists about the potential influence of sexual dimorphism in stature (SDS) within established relationships. The current study investigated the relationship between SDS and the satisfaction, jealousy and mate retention behaviors reported by men and women. Heterosexual men ( n = 98) and women ( n = 102) completed a questionnaire. Men in high SDS relationships reported the lowest levels of cognitive and behavioral jealousy, although the impact of SDS on relationship satisfaction was less clear. SDS was not associated with the overall use of mate retention strategies; SDS did however affect the use of three specific strategies (vigilance, monopolization of time, love and care). SDS did not affect women's relationship satisfaction, jealousy (cognitive, behavioral, or emotional) or the use of mate retention strategies (with the exception of resource display)

Data Scraping as a Cause of Action: Limiting Use of the CFAA and Trespass in Online Copying Cases

In recent years, online platforms have used claims such as the Computer Fraud and Abuse Act (“CFAA”) and trespass to curb data scraping, or copying of web content accomplished using robots or web crawlers. However, as the term “data scraping” implies, the content typically copied is data or information that is not protected by intellectual property law, and the means by which the copying occurs is not considered to be hacking. Trespass and the CFAA are both concerned with authorization, but in data scraping cases, these torts are used in such a way that implies that real property norms exist on the Internet, a misleading and harmful analogy. To correct this imbalance, the CFAA must be interpreted in its native context, that of computers, computer networks, and the Internet, and given contextual meaning. Alternatively, the CFAA should be amended. Because data scraping is fundamentally copying, copyright offers the correct means for litigating data scraping cases. This Note additionally offers proposals for creating enforceable terms of service online and for strengthening copyright to make it applicable to user-based online platforms

Height, Relationship Satisfaction, Jealousy, and Mate Retention

Male height is associated with high mate value. In particular, tall men are perceived as more attractive, dominant and of a higher status than shorter rivals, resulting in a greater lifetime reproductive success. Female infidelity and relationship dissolution may therefore present a greater risk to short men. It was predicted that tall men would report greater relationship satisfaction and lower jealousy and mate retention behavior than short men. Ninety eight heterosexual men in a current romantic relationship completed a questionnaire. Both linear and quadratic relationships were found between male height and relationship satisfaction, cognitive and behavioral jealousy. Tall men reported greater relationship satisfaction and lower levels of cognitive or behavioral jealousy than short men. In addition, linear and quadratic relationships were found between male height and a number of mate retention behaviors. Tall and short men engaged in different mate retention behaviors. These findings are consistent with previous research conducted in this area detailing the greater attractiveness of tall men

A systematic review of reported reassortant viral lineages of influenza A

BACKGROUND: Most previous evolutionary studies of influenza A have focussed on genetic drift, or reassortment of specific gene segments, hosts or subtypes. We conducted a systematic literature review to identify reported claimed reassortant influenza A lineages with genomic data available in GenBank, to obtain 646 unique first-report isolates out of a possible 20,781 open-access genomes. RESULTS: After adjusting for correlations, only: swine as host, China, Europe, Japan and years between 1997 and 2002; remained as significant risk factors for the reporting of reassortant viral lineages. For swine H1, more reassortants were observed in the North American H1 clade compared with the Eurasian avian-like H1N1 clade. Conversely, for avian H5 isolates, a higher number of reported reassortants were observed in the European H5N2/H3N2 clade compared with the H5N2 North American clade. CONCLUSIONS: Despite unavoidable biases (publication, database choice and upload propensity) these results synthesize a large majority of the current literature on novel reported influenza A reassortants and are a potentially useful prerequisite to inform further algorithmic studies.

Teaching Accounting and Finance to non-specialists: revealing the students' perspective on the learning experience

This study is concerned with the non-specialist accounting and finance students’ perspective on the usefulness, scope, and practical application of relevant modules within their program of study. It also evaluates relevant teaching and learning approaches adopted by accounting academics teaching non-specialist - instead of introductory - accounting modules, through revealing the students' perceptions on the effectiveness of these approaches in creating a high quality learning experience. Lectures' teaching competencies are rated first in terms of importance for their learning experience by the vast majority of students. Issues relevant to the curricula's 'real world' application, as well as, the development of clear links between lecture material and assessment practise, engrossed considerable attention by the respondents. Education technology and reading material on the other hand appeared to be of prior importance for a smaller number of students

Two leaf beetles new to Florida (Coleoptera: Chrysomelidae)

Specimens recently submitted to the first author for identification turned out to represent two species of leaf beetles previously unknown from Florida, one of which is new to the eastern United States and the other new to the continental United States

Commerical (terrestrial) and modified solar array design studies for low cost, low power space applications

The suitability of commercial (terrestrial) solar arrays for use in low Earth orbit is examined. It is shown that commercial solar arrays degrade under thermal cycling because of material flexure, and that certain types of silicones used in the construction of these arrays outgas severely. Based on the results, modifications were made. The modified array retains the essential features of typical commercial arrays and can be easily built by commercial fabrication techniques at low cost. The modified array uses a metal tray for containment, but eliminates the high outgassing potting materials and glass cover sheets. Cells are individually mounted with an adhesive and individually covered with glass cover slips, or clear plastic tape. The modified array is found to withstand severe thermal cycling for long intervals of time

Investigation into the effect of plasma pretreatment on the adhesion of parylene to various substrates

A procedure is described for using argon and oxygen plasmas to promote adhesion of parylene coatings upon many difficult-to-bond substrates. Substrates investigated were gold, nickel, kovar, teflon (FEP), kapton, silicon, tantalum, titanium, and tungsten. Without plasma treatment, 180 deg peel tests yield a few g/cm (oz/in) strengths. With dc plasma treatment in the deposition chamber, followed by coating, peel strengths are increased by one to two orders of magnitude

Suspension Design, Modeling, and Testing of a Thermo-Acoustic-Driven Linear Alternator

The Score-Stove™ generates electricity from a wood-burning cooking stove using a thermo-acoustic engine (TAE) that converts heat to sound through a linear alternator (LA). This paper introduces a prototype hemitoroidal suspension that was refined into a segmented trapezoidal shape that gave a higher cyclic life for the LA and includes a critical evaluation that compares a theoretical analysis with experimental results. The results show an improvement from the 40% efficiency of a standard loudspeaker used in reverse as an LA to 70–80% efficiency with the new suspension and a double Halbach array magnetic topology
