CEO servant leadership and firm innovativeness in hotels

Purpose Drawing on the theories of servant leadership and upper echelons, this paper aims to highlight the mechanisms through which CEO servant leadership enhances firm innovativeness in hotels. This study aims to test a multiple mediation model by considering the mediating role of encouragement of participation (EoPART) – a high-performance human resources (HR) practice – and employees’ voice (EVOICE) in sequence. Design/methodology/approach Data were collected from HR managers of 34 hotels in the hospitality industry in Spain, which represents an important international tourist destination. Two methods of rigorous data analysis were used (partial least squares [PLS], structural equation modeling and fuzzy-set qualitative comparative analysis [fs/QCA]), which enabled robust findings to be produced with minimal sample size requirements. Findings CEO servant leadership had a positive indirect effect on firm innovativeness in hotels, via the sequential application of EoPART and EVOICE. Research limitations/implications The findings provide new HR-related insights regarding the encouragement of firm innovativeness in hotels: CEOs can boost innovativeness in their hotels through the development of EoPART systems, which in turn favor EVOICE. Originality/value This is one of the first studies to analyze whether CEO servant leadership has an impact on innovativeness in hotels. Moreover, this study is the first to show the internal mechanisms (EoPART, EVOICE) through which CEO servant leadership encourages hotel innovativeness.
Spectrum allocation issues affecting remote sensing for the 2007 World Radiocommunication Conference (WRC-07)

The 2007 World Radiocommunication Conference will consider a number of possible changes to the International Radio Regulations that have a direct bearing on remote sensing interests throughout the world. Compatibility studies were completed to determine the interference environment for passive sensors in the 1400-1427 MHz, 10.6-10.68 GHz, 23.6-24 GHz, 31.3-31.5 GHz, 36-37 GHz, 50.2-50.4 GHz, and 52.6-54.25 GHz passive bands for WRC-07 Agenda Items 1.2, 1.17 and 1.20. Studies were also completed in support of an extension to the active sensing allocation around 9.5-9.8 GHz in support of Agenda Item 1.3. The results of these studies and the outlook for the remote sensing issues at WRC-07 are discussed.
Finetuning Convolutional Neural Networks for visual aesthetics

Inferring the aesthetic quality of images is a challenging computer vision task due to its subjective and conceptual nature. Most image aesthetics evaluation approaches focused on designing handcrafted features, and only a few adopted learning of relevant and imperative characteristics in a data-driven manner. In this paper, we propose to attune Convolutional Neural Networks (CNNs) for image aesthetics. Unlike previous deep learning based techniques, we employ pretrained models, namely AlexNet [12] and the 16-layer VGGNet [20], and calibrate them to estimate visual aesthetic quality. This enables exploiting automatically the inherent information from much larger scale and more diversified image datasets. We tested our methods on AVA and CUHKPQ image aesthetics datasets on two different training-testing partitions, and compared the performance using both local and contextual information. Experimental results suggest that our strategy is robust, effective and superior to the state-of-the-art approaches.
Sexual Transmission of HIV-1 Among Serodiscordant Couples in Porto Alegre, Southern Brazil

Background: A cohort of 93 heterosexual HIV serodiscordant couples with no prior antiretroviral use were identified in a large referral center from February 2000 to January 2006 in southern Brazil. Methods: Review of clinic records retrospectively identified 56 cases of untreated index cases whereas 37 couples were identified prospectively. Demographics, medical, and laboratory data were obtained. During follow-up, 41/93 index cases (44%) initiated antiretrovirals (ARVs) and from 52 without ARV use, 4 were lost to follow-up. Median viral loads were used to compare transmitters versus nontransmitters (Mann-Whitney test). Results: Sixty-seven (72%) index cases were female (49% identified during ante-natal care). Unprotected sexual intercourse as a risk factor for HIV-1 infection was significantly higher as compared to intravenous drug use (P < 0.0001) in female index partners but not in male index cases. Sexually transmitted diseases were identified in 22 cases (24%). Six HIV-1 seroconversions occurred (6.5%). In all cases index partners were not using ARVs at the time of seroconversion. Among 26 couples with a male index case, there were 4 seroconversions (15%) and among 67 female index cases there were 2 seroconversions (3%). All seroconversions occurred with virus loads >1000 copies/mL. Eight female index cases (22%) reported no condom use. Conclusions: Heterosexual transmission occurred more frequently from HIV-infected males to females (rate ratio 3.5; CI, 95% 0.8–16.5 P = 0.259), although without statistical significance, probably because of the small sample. Transmitters showed significantly higher median viral loads (P = 0.042) suggesting that heterosexual transmission of HIV is more a function of viral load than gender of index case. ARV use may play a role in the prevention of HIV-1 heterosexual transmission. Other factors may be involved and should be further evaluated in larger cohorts.
Does the messenger matter? Studying the impacts of scientists and engineers interacting with public audiences at science festival events

Over the past decade, science festival expos have emerged as popular opportunities for practicing scientists to engage in education outreach with public audiences. In this paper, a partial proportional odds model was used to analyze 5,498 surveys collected from attendees at 14 science expos around the United States. Respondents who report that they interacted with a scientist rated their experiences more positively than those who reported no such interaction on five categories: overall experience, learning, inspiration, fun, and awareness of STEM careers. The results indicate that scientists can positively affect audience perception of their experience at these large-scale public events.
Examining the associations of perceived community racism with self-reported physical activity levels and health among older racial minority adults.

BACKGROUND Racial health disparities are more pronounced among older adults. Few studies have examined how racism influences health behaviors. This study's purpose was to examine how opportunities for physical activity (PA) and community racism are associated with older racial minorities' reported engagement in PA. We also investigated how PA levels influenced health. METHODS We analyzed survey data obtained from a health assessment conducted in 3360 households in Texas, USA, which included items pertaining to PA, community characteristics, and health. RESULTS Our sample contained 195 women and 85 men (mean age 70.16), most of whom were African American. We found no direct relationship between opportunities and PA. Results suggested that perceived community racism moderated this association. When community racism was low, respondents found ways to be active whether they perceived opportunities or not. When community racism was high, perceived lack of opportunities significantly impeded PA engagement. We found the expected association between PA and health. CONCLUSIONS Results suggested that negative effects of community racism were counteracted through increased opportunities for PA.

Rationale for Chemotherapy, Immunotherapy, and Checkpoint Blockade in SCLC: Beyond Traditional Treatment Approaches

Introduction: Small cell lung cancer (SCLC) is an aggressive malignancy that although initially sensitive to chemo- and radiation therapy, inevitably relapses resulting in poor survival. Increasing evidence suggests that immune responses against SCLC cells make immunotherapy a viable therapeutic approach. Furthermore, preclinical data have shown that certain chemotherapeutic regimens may augment the immunotherapeutic response in SCLC. This review discusses current evidence supporting immunotherapy for SCLC, progress made, and ongoing clinical trials. Methods: We searched PubMed and abstracts presented at recent oncology congresses for publications on the clinical benefit of immunotherapy/checkpoint blockade for treatment of SCLC. Results: Preliminary data from ongoing clinical trials in SCLC have shown that some antiangiogenic agents, vaccines, and immunomodulators, including interferon-&agr; and immune checkpoint blockers (i.e., anticytotoxic T-lymphocyte-associated antigen-4 [CTLA-4] antibodies) may be efficacious as single agents and in combination with standard-of-care regimens. Notably, in a phase II trial, ipilimumab—a fully human anti-CTLA-4 monoclonal antibody recently approved for treatment of unresectable or metastatic melanoma—demonstrated encouraging results when used as part of a chemoimmunotherapeutic regimen in patients with SCLC. Ipilimumab is undergoing further investigation in this population. Conclusions: Treatment options for SCLC are limited and prognosis poor, emphasizing the need for novel treatments. Although current strategies successfully induce a response, the response is not durable. Evidence of an immune response in SCLC and a better understanding of the immunosuppressive tumor environment support the combinatorial use of immunomodulators, such as ipilimumab, with traditional chemotherapy regimens to improve patient outcomes and potentially sustain the effect from chemotherapeutic induction.
Dynamic mode stability analysis of surface relief VCSELs under strong RF modulation

We demonstrate that a carefully designed fundamental-mode stabilized vertical-cavity surface-emitting laser (VCSEL) using a shallow surface relief can maintain a large sidemode suppression ratio (SMSR) under strong radio frequency modulation. A number of VCSELs emitting at 850 nm, with different surface relief and oxide aperture diameters, have been experimentally investigated. For certain combinations of these diameters, the SMSR exceeds 30 dB at 2- and 5-GHz operation, even for as much as 15 dBm of input modulation power.
Top Management Team Characteristics and Financial Reporting Quality

The accounting literature often views managers as individuals whose financial reporting decisions are determined by their economic incentives and individual characteristics. However, managers typically work in a team and most decisions have at least some input from other members of the team. This study examines the impacts of two top management team (TMT) characteristics on financial reporting quality. The results indicate that background homogeneity and long-shared working experience are each distinctly related to a higher likelihood of restatements. Additional tests document that team homogeneity and shared experience also are positively associated with discretionary accruals for firms with income-increasing earnings management incentives. Moreover, the impact of TMTs on financial reporting quality varies with the proportion and tenure of independent directors. These findings indicate that top management team characteristics are important determinants of financial reporting quality. JEL Classifications: G34; M14; M41; M54.
Transcriptional Properties of Ptx1 and Ptx2 Isoforms

The Ptx (Pitx) family of homeobox transcription factors comprises Ptx1, Ptx2 and Ptx3. Ptx1 and Ptx2 are expressed in the stomodeum and its derivatives including the pituitary, as well as in mesodermal derivatives, whereas Ptx3 is expressed in one neuronal lineage of the brain and in the eyes. A large set of downstream target genes have been identified for Ptx1 in the pituitary gland where it acts as a pan-pituitary regulator of transcription. In particular, Ptx1 contributes to promoter- and lineage-specific transcription by interaction with cell-restricted factors such as SF-1, Egr-1, Pit1, and the basic helix-loop-helix heterodimer NeuroD1/Pan1. We describe the cloning from pituitary cells and the characterization of a Ptx1 isoform, named Ptx1b, generated by alternative promoter usage. The two Ptx1 and two Ptx2 isoforms have similar in vitro DNA binding specificities and they all activate transcription driven by a panel of pituitary promoters, including those for proopiomelanocortin, αGSU, LHβ, FSHβ, GnRH-R, TSHβ, PRL, and GH. Also like Ptx1, the Ptx1b, Ptx2a, and Ptx2b transcription factors synergize with the structurally unrelated factors SF-1, Egr-1, Pit1, and NeuroD1/Pan1 to activate promoter-specific transcription. In conclusion, the pituitary transcriptional activities of the four Ptx isoforms do not appear to be dependent on the variant N-termini of these factors.
The Unintended Consequences of Accounting Harmonization in a Transition Country: A Case Study of Management Accounting of Private Czech Companies

The paper addresses the impact of adoption of International Financial Reporting Standards on the mutual relations between financial and management accounting of private Czech companies under foreign control. Being acquired by a parent company, a subsidiary loses its independence and faces institutional duality, as it must respond to the parent’s directives and is simultaneously confronted with local pressures. Using data from a survey, the logistic regression model provides evidence that subsidiaries under foreign control steadily integrate IFRS-based principles into their management accounting subsystems. The study extends current research on the integration of management and financial accounting by identifying a special case from a transition country where management accounting of subsidiaries converges with financial accounting of parents. A radical change in the traditional organization of management accounting is the strategic response of subsidiaries to the constraints of the local regulatory framework for financial reporting and taxation. However, aligning subsidiary practices with the parent’s goals is conditioned by the existence of a functioning compensation scheme of the subsidiary’s management with reference to IFRS-based results.
[Validity and reproducibility of a questionnaire on physical activity and non-activity for school children in Mexico City].

OBJECTIVE To assess the validity and reproducibility of a self-reported questionnaire on physical activity and inactivity, developed for children aged 10-14 in Mexico City. MATERIAL AND METHODS Between May and December 1996, a self-reported physical activity and inactivity questionnaire was developed and applied twice to a sample of 114 students aged 10 to 14, from a low and middle income population of Mexico City. The children's mothers completed the same questionnaire, and two 24-hour recalls of physical activity were used for comparison. Statistical analysis consisted of central tendency and dispersion measures and Pearson's correlation coefficient. RESULTS Correlations between hours per day spent in physical activity and inactivity from the children's questionnaire and the 24-hour recall data, were 0.03 for moderate activity, 0.15 for vigorous activity, and 0.51 (p = 0.001) for watching television, adjusted by age, gender, town, and illness prior to the administration of the questionnaire. Compared to the 24-hour recall data, the questionnaire overestimated the time spent watching television, reading or participating in vigorous activity, and underestimated the time engaged in moderate activity. Statistically significant (p < 0.05) six-month reproducibility values were observed for watching television (r = 0.53), sleeping (r = 0.40), moderate (r = 0.38), and vigorous activity (r = 0.55). CONCLUSIONS Among children of Mexico City aged 10-14, the questionnaire showed acceptable validity in estimating the time watching television, and acceptable reproducibility of the time watching television, vigorous and moderate activity.
Differences between recognition and resolution acuity in patients undergoing macular hole surgery.

PURPOSE The present investigation compared recognition acuities (ETDRS chart) with resolution acuities (Landolt-C chart) in a sample of patients with idiopathic macular holes (MH). Traditionally, visual acuity in a clinical setting is measured with a letter chart. Yet, the ability to recognize a letter differs from a resolution task, such as detecting the direction of a gap in a ring. It was hypothesized that resolution acuity would be more impaired than recognition acuity in patients with MH, because component cues in letter optotypes are not available in Landolt-Cs. METHOD Visual acuities of 23 patients with MH (age range, 52-82) were tested, using standard ETDRS and Landolt-C charts. Optical coherence tomography was used to confirm the diagnosis of MH. RESULTS Acuities correlated strongly, before and after surgery (r = 0.92 and r = 0.95, respectively). However, paired t-tests determined that resolution acuity was significantly more impaired at both time points than was recognition acuity (P < 0.001). Using Bland-Altman plots, the limits of agreement between the two acuity types indicated that resolution acuity differed from recognition acuity by up to five lines before surgery and up to 3 lines after surgery. CONCLUSIONS ETDRS and Landolt-C acuities differ in a clinically significant way in patients before and after MH surgery. Measuring recognition acuity by reading letters may lead to an overestimate of visual ability at the retinal level in patients with MH by including compensatory top-down cognitive processes that are unavailable for resolution tasks.
Bone response to hydroxyapatite‐coated and commercially pure titanium implants in the human arthritic knee

Rough and smooth commercially pure (c.p.) titanium implants and hydroxy‐apatite‐coated (HA‐C) implants were inserted in arthritic human knees and left in situ in order to compare the response of bone to these three implants. Radiographic examination alone could not determine if bone apposition had occurred. After 3 and 6 months, histomorphometric analyses of undecalcified sections, 10 μm thick, revealed a statistical significance in the amount of bone apposition to rough‐surfaced and HA‐C implants as compared with smooth uncoated implants. Most of the rough‐surfaced c.p. titanium implants and the HA‐C implants had achieved bone apposition on the order of 50%. No statistically significant differences in apposition were seen between the rough‐surfaced and HA‐C implants. The smooth c.p. titanium implants were mostly encapsulated in fibrous tissue.
An updated and upgraded L1CAM mutation database

The L1 syndrome is an X‐linked recessive disease caused by mutations in the L1CAM gene. To date more than 200 different mutations have been reported, scattered over the entire gene, about 35% being missense mutations. Although it is tempting to consider these missense mutations as being disease‐causing, one should be careful in drawing any firm conclusions, unless there is additional supporting information. This is in contrast to truncating mutations, which are always considered to be disease‐causing, unless they involve truncations close to the gene stop codon. In order to allow conclusions to be drawn on the disease‐causing nature of L1CAM (missense) mutations, we have updated and upgraded our LICAM mutation database with more pathogenicity data and clinical information collected from the literature or generated by our own research. As a result, the renewed database offers condensed scientific information, allowing conclusions to be drawn on the pathogenicity and severity of LICAM mutations based on multiple factors.

Identification of D3 and σ Receptors in the Rat Striatum and Nucleus Accumbens Using (±)‐7‐Hydroxy‐N,N‐Di‐n‐[3H]Propyl‐2‐Aminotetralin and Carbetapentane

Abstract: Cross‐reactions between dopamine D3 and σ receptor ligands were investigated using (±)‐7‐hydroxy‐N,N‐di‐n‐[3H]propyl‐2‐aminotetralin [(±)‐7‐OH‐[3H]DPAT], a putative D3‐selective radioligand, in conjunction with the unlabeled σ ligands 1,3‐di(2‐tolyl)guanidine (DTG), carbetapentane, and R(−)‐N‐(3‐phenyl‐1‐propyl)‐1‐phenyl‐2‐aminopropane [R(−)‐PPAP]. In transfected CCL1.3 mouse fibroblasts expressing the human D3 receptor, neither DTG nor carbetapentane (0.1 µM) displaced (±)‐7‐OH‐[3H]DPAT binding. R(−)‐PPAP (0.1 µM) displaced 39.6 ± 1.0% of total (±)‐7‐OH‐[3H]DPAT binding. In striatal and nucleus accumbens homogenates, (±)‐7‐OH‐[3H]DPAT labeled a single site (15–20 fmol/mg of protein) with high (1 nM) affinity. Competition analysis with carbetapentane defined both high‐ and low‐affinity sites in striatal (35 and 65%, respectively) and nucleus accumbens (59 and 41%, respectively) tissue, yet R(−)‐PPAP identified two sites in equal proportion. Carbetapentane and R(−)‐PPAP (0.1 µM) displaced ∼20–50% of total (±)‐7‐OH‐[3H]DPAT binding in striatum, nucleus accumbens, and olfactory tubercle in autoradiographic studies, with the nucleus accumbens shell subregion exhibiting the greatest displacement. To determine directly (+)‐7‐OH‐[3H]DPAT binding to σ receptors, saturation analysis was performed in the cerebellum while masking D3 receptors with 1 µM dopamine. Under these conditions (+)‐7‐OH‐[3H]DPAT labeled σ receptors with an affinity of 24 nM. These results suggest that (a) (±)‐7‐OH‐[3H]DPAT binds D3 receptors with high affinity in rat brain and (b) a significant proportion of (±)‐7‐OH‐[3H]DPAT binding consists of σ1 sites and the percentages of these sites differ among the subregions of the striatum and nucleus accumbens.
