    A growing body of research reveals that lesbian, gay, bisexual, transgender, and queer (LGBTQ) people experience a disproportionate amount of mental health challenges when compared with those who are heterosexual and cisgender. LGBTQ people, in general, have a higher prevalence of suicidal thoughts, attempts, and completions (Hatzenbuehler, 2011); depression and anxiety (Cochran, Sullivan, & Mays, 2003), and substance use and abuse (Marshal et al., 2008). LGBTQ people are more likely than heterosexual or cisgender people to have histories of childhood sexual abuse (Balsam, Lehavot, Beadnell, & Circo, 2010) and are more likely to be homeless (Rosario, Schrimshaw, & Hunter, 2012).This is true of young LGBTQ people as well. Studies find that young adults under 24 years of age who identify as LGBTQ, have a higher likelihood of depression and suicide than heterosexual youth (Marshal et al., 2013), are more likely to engage in self-harming behaviors (Jiang et al., 2010), and have increased rates of being a victim of bullying (Berlan, Corliss, Field, Goodman, & Austin, 2010) than their heterosexual counterparts

    A Critical Assessment of the Traditional Residential Real Estate Broker Commission Rate Structure

    While real estate brokers have long set their fee as a straight percentage of a home's sale price, this formula is an anomaly and a primary reason why such fees may be inflated by more than $30 billion annually. Although competitive pressures ordinarily produce a fee structure reflecting costs, real estate broker commissions are strangely unrelated to either the quantity or quality of the service rendered or even to the value provided. Rather, this fee has been based solely on the price of the home. (It is as if divorce lawyers set their fee as a flat percentage of a client's net value, irrespective of whether the divorce was amicable without kids or involved bitterly contested custody and other issues . Oddly, not only is there no evidence that it is any more costly to sell higher-priced homes than median-priced properties, but it is possible that the opposite may be true! Furthermore, the straight percentage fee formula creates little incentive for real estate agents to provide home buyers or sellers with additional value. The article analyzes five elements of the traditional residential real estate broker rate structure, the most important of which are: 1) setting fees as a percentage-of-sale-price, 2) letting the seller's broker set the fee received by the buyer's broker, and 3) refusing to unbundle the price of a full package of services. After explaining the conditions under which such rate elements would be justified, this article finds that those conditions do not generally exist in the real estate brokerage market. Moreover, it identifies more than a half dozen harms that the rate elements cause to home buyers and sellers. For example, buyers are often not alerted to attractive homes because the rate structure leads traditional agents to intentionally avoid showing them. Meanwhile, many buyers do not even consider negotiating the fee paid to their broker because the rate structure causes them to believe their brokers' services cost them nothing. After this criticism, the article suggests that consumers would benefit most from a fee-for-service approach, combining flat fees, hourly fees, and bonuses, including percentages of extra value created, and it identifies currently available examples of some of these options. After reviewing eight reasons why incumbents are able to protect the current structure, the article suggests four questions that consumer media should teach consumers to ask to help undermine the industry's protectionist practices.Other Topics

    Autonomous learning and reproduction of complex sequences: a multimodal architecture for bootstraping imitation games

    This paper introduces a control architecture for the learning of complex sequence of gestures applied to autonomous robots. The architecture is designed to exploit the robot internal sensory-motor dynamics generated by visual, proprioceptive, and predictive informations in order to provide intuitive behaviors in the purpose of natural interactions with humans

    The Late Natufian at Raqefet Cave: The 2006 Excavation Season

    Get PDF
    A long season of excavation took place at Raqefet cave during the summer of 2006. In the first chamber we exposed an area rich with Natufian human burials (Locus 1), a large bedrock basin with a burial and two boulder mortars (Locus 2), an in situ Natufian layer (Locus 3), and two areas with rich cemented sediments (tufa) covering the cave floor (Loci 4, 5). The latter indicate that at the time of occupation the Natufian layers covered the entire floor of the first chamber. During the ensuing millennia, these were washed away and/or removed by later visitors to the cave. We found in the cave and the terrace almost 80 human-made bedrock holes (most of which are commonly but somewhat erroneously termed mortars and cupmarks). Several contained in situ Natufian remains, and at the top of one a human skeleton was unearthed. The variety of the HBHs, in terms of shape and dimensions indicates that they were used in many ways, some of which could not have been for food or mineral processing. The paper provides results of on-going studies regarding the burials, the HBHs, the flint assemblage, the faunal remains, the ground stone industry, the bone tools and the beads. It also presents aspects of geoarchaeology and ground penetrating radar analyses. Some of the detailed plans and sections were prepared by the use of photogrammetry

    Stability of average roughness, octahedrality, and strong diameter 2 properties of Banach spaces with respect to absolute sums

    Get PDF
    We prove that, if Banach spaces XX and YY are Ī“\delta-average rough, then their direct sum with respect to an absolute norm NN is Ī“/N(1,1)\delta/N(1,1)-average rough. In particular, for octahedral XX and YY and for pp in (1,āˆž)(1,\infty) the space XāŠ•pYX\oplus_p Y is 21āˆ’1/p2^{1-1/p}-average rough, which is in general optimal. Another consequence is that for any Ī“\delta in (1,2](1,2] there is a Banach space which is exactly Ī“\delta-average rough. We give a complete characterization when an absolute sum of two Banach spaces is octahedral or has the strong diameter 2 property. However, among all of the absolute sums, the diametral strong diameter 2 property is stable only for 1- and āˆž\infty-sums.Comment: 19 pages, 2 figure

    Survival and Phenology of \u3ci\u3eAgrilus Planipennis\u3c/i\u3e (Coleoptera: Buprestidae) Reared on a Newly Developed Artificial Diet Free of Host Material

    The final phase in the development of an artificial diet that contains no ash host material and the phenology of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Bupresidae) on that diet are documented. A diet containing powdered ash phloem exists, but host material introduces potential variability and contamination, and the cost and effort needed to collect and process it can be high. The post-embryonic development of A. planipennis was evaluated on four artificial diets lacking host material, and effects of variations in diet layer thickness and moisture content were also investigated. The best diet and rearing method resulted in 67.8% survival to pupation and 51% to adult. Larval size and development rate were comparable to published accounts for emerald ash borer larvae developing on susceptible host plants. Important advances include reduction of antimicrobial components to the lowest functional level; change of protein sources from wheat germ, brewerā€™s yeast, and casein to soy flour and casein; reduction of diet moisture content to 50%; and adding a fresh layer of diet to spent diet half-way through larval development. The artificial diet represents a step toward the development of a standardized mass- production system for A. planipennis

    A Developmental Approach for low-level Imitations

    Get PDF
    Historically, a lot of authors in psychology and in robotics tend to separate "true imitation" and its related high-level mechanisms which seem to be exclusive to human adult, from low-level imitations or "mimicries" observed on babies or primates. Closely, classical researches suppose that an imitative artificial system must be able to build a model of the demonstrator's geometry, in order to reproduce finely the movements on each joints. Conversely, we will advocate that if imitation is viewed as a part of a developmental course, then (1) an artificial developing system does not need to build any internal model of the other, to perform real-time and low-level imitations of human movements despite the related correspondence problem between man and robot and, (2) a simple sensory-motor loop could be at the basis of multiples heterogeneous imitative behaviors often explained in the literature by different models
