Applicant Reactions to Artificial Intelligence in the Selection Process

The use of advanced technology such as artificial intelligence (AI) in the selection process has become an increasingly popular practice within organizations. However, little research has examined how applicants react to these new procedures and how those reactions may affect outcomes such as perceptions of fairness, organizational attraction, and job pursuit intentions. Previous research has suggested that the use of technology in the selection process may lead to more negative outcomes when compared to using traditional selection procedures such as face-to-face interviewing. The purpose of this study is to examine applicant reactions to the use of advanced decision-making technologies in the selection process, such as artificial intelligence systems that make hiring decisions. Determining how applicants react to the use of technology in the selection process serves to help organizations better understand how these practices affect job seekers’ perceptions of the organization. The results of this study may help organizations weigh the pros and cons of using computer information systems to select applicants instead of using a traditional selection procedure

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae)

Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood whilst maintaining the same mode of locomotion throughout life. These ontogenetic characteristics stimulate biomechanical questions about the strategies that allow emus to cope with their rapid growth and locomotion, which can be partly addressed via scaling (allometric) analysis of morphology. In this study we have collected pelvic limb anatomical data (muscle architecture, tendon length, tendon mass and bone lengths) and calculated muscle physiological cross sectional area (PCSA) and average tendon cross sectional area from emus across three ontogenetic stages (n = 17, body masses from 3.6 to 42 kg). The data were analysed by reduced major axis regression to determine how these biomechanically relevant aspects of morphology scaled with body mass. Muscle mass and PCSA showed a marked trend towards positive allometry (26 and 27 out of 34 muscles respectively) and fascicle length showed a more mixed scaling pattern. The long tendons of the main digital flexors scaled with positive allometry for all characteristics whilst other tendons demonstrated a less clear scaling pattern. Finally, the two longer bones of the limb (tibiotarsus and tarsometatarsus) also exhibited positive allometry for length, and two others (femur and first phalanx of digit III) had trends towards isometry. These results indicate that emus experience a relative increase in their muscle force-generating capacities, as well as potentially increasing the force-sustaining capacities of their tendons, as they grow. Furthermore, we have clarified anatomical descriptions and provided illustrations of the pelvic limb muscle–tendon units in emus

Therapeutic touch for healing acute wounds

Background Therapeutic Touch (TT) is an alternative therapy that has gained popularity over the past two decades for helping wounds to heal. Practitioners enter ameditative state and pass their hands above the patient’s body to find and correct any imbalances in the patient’s ’life energy’ or chi. Scientific instruments have been unable to detect this energy. The effect of TT on wound healing has been expounded in anecdotal publications. Objectives To identify and review all relevant data to determine the effects of TT on healing acute wounds. Search methods For this fourth update, we searched The Cochrane Wounds Group Specialised Register (searched 27 January 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1); Ovid MEDLINE (2010 to January Week 2 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, January 26, 2012); Ovid EMBASE (2010 to 2012 Week 03); and EBSCO CINAHL (2010 to January 6 2012). Selection criteria All randomised or quasi-randomised controlled trials, which compared the effect of TT with a placebo, another treatment, or no treatment control were considered. Studies which used TT as a stand-alone treatment, or as an adjunct to other therapies, were eligible. Data collection and analysis One author (DO’M) determined the eligibility for inclusion of all trials in the review. Both authors conducted data extraction and evaluation of trial validity independently. Each trial was assessed using predetermined criteria. Main results No new trials were identified for this update. Four trials in people with experimental wounds were included. The effect of TT on wound healing in these studies was variable. Two trials (n = 44 & 24) demonstrated a significant increase in healing associated with TT, while one trial found significantly worse healing after TT and the other found no significant difference. All trials are at high risk of bias. Authors’ conclusions There is no robust evidence that TT promotes healing of acute wounds

The relationship of the neo-angiogenic marker, endoglin, with response to neoadjuvant chemotherapy in breast cancer

Endoglin (CD105) is upregulated in endothelial cells of tissues undergoing neovascularisation. A greater number of CD105-positive vessels predicts poor survival in breast cancer. We examine whether CD105 expression predicts response to neoadjuvant chemotherapy. Fifty-seven women (median age 50 years, range 29–70) received neoadjuvant chemotherapy for operable breast cancer. Immunohistochemical staining using monoclonal antibodies to CD105 and CD34 was performed on pretreatment biopsies and post-treatment surgical specimens. Individual microvessels were counted in 10 random fields at × 200 magnification. Median counts were correlated with clinical and pathological response using the Mann–Whitney U-test. Forty-five out of fifty-seven patients (79%) responded clinically, 22 (39%) responded pathologically. On pretreatment biopsies, clinical responders had significantly lower median CD105-positive vessel counts than nonresponders (median counts 5 and 9.3/high-power field (hpf), median difference=4.0/hpf, 95% CI 0.5–8.0/hpf, P=0.02). For pathological responders and nonresponders, median counts were 4.8 and 5.5/hpf (median difference –0.5/hpf, 95% CI=−2.5–2.0/hpf, P=0.77). CD34 expression (total microvessel density) did not correlate with response. Pretreatment CD105 expression predicts for clinical response to chemotherapy, with a lower initial count being favourable. Patients with high baseline new vessel counts or increased counts after conventional therapy may benefit from additional antiangiogenic therapy

MOSAIC (MOthers' Advocates In the Community): protocol and sample description of a cluster randomised trial of mentor mother support to reduce intimate partner violence among pregnant or recent mothers

Background : Intimate partner violence (IPV) is prevalent globally, experienced by a significant minority of women in the early childbearing years and is harmful to the mental and physical health of women and children. There are very few studies with rigorous designs which have tested the effectiveness of IPV interventions to improve the health and wellbeing of abused women. Evidence for the separate benefit to victims of social support, advocacy and non-professional mentoring suggested that a combined model may reduce the levels of violence, the associated mental health damage and may increase a woman\u27s health, safety and connection with her children. This paper describes the development, design and implementation of a trial of mentor mother support set in primary care, including baseline characteristics of participating women.Methods/Design : MOSAIC (MOtherS\u27 Advocates In the Community) was a cluster randomised trial embedded in general practice and maternal and child health (MCH) nursing services in disadvantaged suburbs of Melbourne, Australia. Women who were pregnant or with infants, identified as abused or symptomatic of abuse, were referred by IPV-trained GPs and MCH nurses from 24 general practices and eight nurse teams from January 2006 to December 2007. Women in the intervention arm received up to 12 months support from trained and supported non-professional mentor mothers. Vietnamese health professionals also referred Vietnamese women to bilingual mentors in a sub-study. Baseline and follow-up surveys at 12 months measured IPV (CAS), depression (EPDS), general health (SF-36), social support (MOS-SF) and attachment to children (PSI-SF). Significant development and piloting occurred prior to trial commencement. Implementation interviews with MCH nurses, GPs and mentors assisted further refinement of the intervention. In-depth interviews with participants and mentors, and follow-up surveys of MCH nurses and GPs at trial conclusion will shed further light on MOSAIC\u27s impact.Discussion : Despite significant challenges, MOSAIC will make an important contribution to the need for evidence of effective partner violence interventions, the role of non-professional mentors in partner violence support services and the need for more evaluation of effective health professional training and support in caring for abused women and children among their populations.<br /
