“Brick & Mortar” Education and “Real World” Experience: Assessing HRM Alumni Perceptions of their Early Professional Development

In this research we examined the extent to which three distinct human resource management (HRM) undergraduate programs provide coverage of the 13 core content areas specified by the Society for Human Resource Management (SHRM) and explored the usefulness of various ways of learning including their undergraduate coursework, an internship, and previous work experience as related to early professional development. Based on perceptions of HRM alumni, the findings reveal that the three curricula provided significant differences in levels of proficiency in seven of the core areas and in perceived usefulness of the learning methods. Implications for HRM curriculum development and students’ professional development are discussed

The Impact of Passing the Professional in Human Resources Exam on Early Career Success for Undergraduates Entering the Human Resource Field

This study investigates the impact of passing the Professional in Human Resources (PHR) certification exam on the early career success of recent college graduates. Data were gathered from alumni of three Midwestern universities who earned an undergraduate degree in business administration (i.e., BBA) with a major in human resources. The survey was designed to measure early career success indicators including finding a job in the HR field, starting salary, and number of promotions. Results reveal that the probability of one’s first job after graduation being in human resources was significantly greater for those who had passed the PHR exam compared with those who did not pass or did not take the exam. Passing the PHR exam was not associated with significant differences in starting salary or early career promotions. Implications, study strengths and limitations, and suggestions for future research are discussed

Evaluation of the burden of HPV-related hospitalizations as a useful tool to increase awareness: 2007–2017 data from the sicilian hospital discharge records

In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = −9.9%, p < 0.001). The median age for cervical cancer was 45 years old, with an increasing value from 43 to 47 years (p < 0.001). The age classes with greater decreases in hospital admissions for invasive cancers were women aged 35 years or more (APC range from −5.5 to −9.86) and 25–34 years old (APC = −11.87, p < 0.001) for women with cervical carcinoma in situ. After ten years for vaccine introduction and sixteen years for cervical cancer screening availability, a relatively large decrease in hospital admissions for cervical cancer and other HPV-related diseases in Sicily was observed. Some clinical characteristics of hospitalization, such as increasing age, are suggestive clues for the impact of preventive strategies, but further research is needed to confirm this relationship

“Dirty” Workplace Politics and Well-Being: The Role of Gender

We build and empirically test an integrative model of gender, workplace politics, and stress by integrating social role theory and prescriptive gender stereotypes with the transactional theory of stress. To examine the effect of gender on the relation between exposure to non-sanctioned political influence tactics (NPITs; e.g., self-serving and socially undesirable behaviors such as manipulation and intimidation) and stress outcomes, we employed a daily diary design with 64 employed adults over the course of 12 working days. In support of our hypotheses, exposure to NPITs––that is, “dirty politics”––elicited a threat appraisal that, in turn, related to the activation of negative emotions. Moreover, unlike men, women who reported higher levels of NPITs experienced heightened levels of threat appraisal and ultimately negative emotions. We demonstrate that pairing social role theory with the transactional theory of stress is a useful approach for researchers interested in better understanding gender differences in the occupational stress process. Anyone interested in reducing stress in the workplace is encouraged not only to reduce the occurrence of NPITs, but also to consider ways to reduce the threat associated with them, especially for women

Pro-invasive stimuli and the interacting protein Hsp70 favour the route of alpha-enolase to the cell surface

Cell surface expression of alpha-enolase, a glycolytic enzyme displaying moonlighting activities, has been shown to contribute to the motility and invasiveness of cancer cells through the protein non-enzymatic function of binding plasminogen and enhancing plasmin formation. Although a few recent records indicate the involvement of protein partners in the localization of alpha-enolase to the plasma membrane, the cellular mechanisms underlying surface exposure remain largely elusive. Searching for novel interactors and signalling pathways, we used low-metastatic breast cancer cells, a doxorubicin-resistant counterpart and a non-tumourigenic mammary epithelial cell line. Here, we demonstrate by a combination of experimental approaches that epidermal growth factor (EGF) exposure, like lipopolysaccharide (LPS) exposure, promotes the surface expression of alpha-enolase. We also establish Heat shock protein 70 (Hsp70), a multifunctional chaperone distributed in intracellular, plasma membrane and extracellular compartments, as a novel alpha-enolase interactor and demonstrate a functional involvement of Hsp70 in the surface localization of alpha-enolase. Our results contribute to shedding light on the control of surface expression of alpha-enolase in non-tumourigenic and cancer cells and suggest novel targets to counteract the metastatic potential of tumours

Introducing Relational Values as a Tool for Shark Conservation, Science, and Management

Relational values (RV) are values that arise from a relationship with nature, encompassing a sense of place, feelings of well-being (mental and physical health), and cultural, community, or personal identities. With sharks, such values are formed by diverse groups that interact with these animals and their ecosystems, either physically or virtually, whether a scientist, student, fisher, or media-viewer. Further, these user groups may overlap or come into conflict over management plans, media portrayals of sharks, and their conservation status. Although scientists have not explicitly aimed to assess RV through sharks, qualitative studies of shark fishers, tourism operators, tourists, and the public, as well as historical and archeological accounts, can be interpreted through an analytical lens to reveal values which can also be defined as relational. To this end, this review considers studies capturing RV alongside those of economic value (increasingly, the value of a shark is appraised by their financial value in shark tourism) and the social and cultural roles of sharks. Based on these studies and the broader RV literature, we then outline a workflow for how RV can be leveraged in scientific inquiry, equitable resource management, and education. We conclude that via collaborative assessments of RV, with implicit inclusion of multiple values of sharks and by acknowledging their importance to all parties involved in user conflicts, the RV framework can lead to a constructive dialog on polarizing conservation and management issues. By illuminating shared values, and/or revealing dichotomies of values ascribed toward certain areas or objects, this framework can provide inroads to mediation, seeking to conserve or even restore relationships with nature, and their derived values as much as is possible. This approach can yield unexpected knowledge, solutions, and compromises in an increasingly complex conservation landscape

Spitzer Observations of IC 2118

IC 2118, also known as the Witch Head Nebula, is a wispy, roughly cometary, ~5 degree long reflection nebula, and is thought to be a site of triggered star formation. In order to search for new young stellar objects (YSOs), we have observed this region in 7 mid- and far-infrared bands using the Spitzer Space Telescope and in 4 bands in the optical using the U. S. Naval Observatory 40-inch telescope. We find infrared excesses in 4 of the 6 previously-known T Tauri stars in our combined infrared maps, and we find 6 entirely new candidate YSOs, one of which may be an edge-on disk. Most of the YSOs seen in the infrared are Class II objects, and they are all in the "head" of the nebula, within the most massive molecular cloud of the region.Comment: Accepted to Ap

Cryptic Leishmania infantum infection in Italian HIV infected patients

<p>Abstract</p> <p>Background</p> <p>Visceral leishmaniasis (VL) is a protozoan diseases caused in Europe by <it>Leishmania (L.) infantum</it>. Asymptomatic <it>Leishmania </it>infection is more frequent than clinically apparent disease. Among HIV infected patients the risk of clinical VL is increased due to immunosuppression, which can reactivate a latent infection. The aims of our study were to assess the prevalence of asymptomatic <it>L. infantum </it>infection in HIV infected patients and to study a possible correlation between <it>Leishmania </it>parasitemia and HIV infection markers.</p> <p>Methods</p> <p>One hundred and forty-five HIV infected patients were screened for the presence of anti-<it>Leishmania </it>antibodies and <it>L. infantum </it>DNA in peripheral blood. Statistical analysis was carried out by using a univariate regression analysis.</p> <p>Results</p> <p>Antibodies to <it>L. infantum </it>were detected in 1.4% of patients. <it>L. infantum </it>DNA was detected in 16.5% of patients. Significant association for PCR-<it>Leishmania </it>levels with plasma viral load was documented (p = 0.0001).</p> <p>Conclusion</p> <p>In our area a considerable proportion of HIV infected patients are asymptomatic carriers of <it>L. infantum </it>infection. A relationship between high HIV viral load and high parasitemic burden, possibly related to a higher risk of developing symptomatic disease, is suggested. PCR could be used for periodic screening of HIV patients to individuate those with higher risk of reactivation of <it>L. infantum </it>infection.</p

Cryo-electron tomography of cells: connecting structure and function

Cryo-electron tomography (cryo-ET) allows the visualization of cellular structures under close-to-life conditions and at molecular resolution. While it is inherently a static approach, yielding structural information about supramolecular organization at a certain time point, it can nevertheless provide insights into function of the structures imaged, in particular, when supplemented by other approaches. Here, we review the use of experimental methods that supplement cryo-ET imaging of whole cells. These include genetic and pharmacological manipulations, as well as correlative light microscopy and cryo-ET. While these methods have mostly been used to detect and identify structures visualized in cryo-ET or to assist the search for a feature of interest, we expect that in the future they will play a more important role in the functional interpretation of cryo-tomograms
