    Functional relations modulate the responsiveness to affordances despite the impact of conflicting stimulus-response mappings

    The study investigated how conflicting stimulus-response mappings influenced affordance processing given a manipulation of the functional relations. Participants performed a task involving consistent-inconsistent stimulus-response mappings: Implicit Relational Assessment Procedure (IRAP). They were instructed to confirm or to deny a relation between words and tool-objects (consistent blocks) or to provide non-conventional responses (inconsistent blocks). The relations between stimuli could functionally match (e.g., Kitchen- Spatula) or not (e.g., Kitchen- Hammer), as well as the spatial relations (e.g., a match or a mismatch between participants' hand response and the tool-object orientation). The results showed faster reaction times (RTs) when functional relations between stimuli matched both in consistent and inconsistent blocks. Differences in RTs and accuracy between consistent and inconsistent blocks were only found when the functional relation between stimuli matched. No modulation of the performance was observed for mismatching functional relations and spatial relations between blocks. These results support the hypothesis that the responsiveness to affordances is strongly modulated by matching functional relations, despite the impact of conflicting stimulus-response mappings

    Characterization of the optical and X-ray properties of the northwestern wisps in the Crab Nebula

    We have studied the wisps to the north-west of the Crab pulsar as part of a multi-wavelength campaign in the visible and in X-rays. Optical observations were obtained using the Nordic Optical Telescope in La Palma and X-ray observations were made with the Chandra X-ray Observatory. The observing campaign took place from 2010 October until 2012 September. About once per year we observe wisps forming and peeling off from (or near) the region commonly associated with the termination shock of the pulsar wind. We find that the exact locations of the northwestern wisps in the optical and in X-rays are similar but not coincident, with X-ray wisps preferentially located closer to the pulsar. This suggests that the optical and X-ray wisps are not produced by the same particle distribution. Our measurements and their implications are interpreted in terms of a Doppler-boosted ring model that has its origin in magne- tohydrodynamic (MHD) modelling. While the Doppler boosting factors inferred from the X-ray wisps are consistent with current MHD simulations of pulsar wind nebulae (PWN), the optical boosting factors are not, and typically exceed values from MHD simulations by about a factor of 3.Comment: 11 pages, 12 figure

    Joint Responsibility for the Operationof the Enterprise: Workplace Reform at BHP New Zealand

    Get PDF
    Ryan's (1994 )framework for understanding the essential components of workplace reform ties management notions of quality and continuous improvement- key 'drivers' in New Zealand business today- to union concerns about shared decision-making and joint responsibility between management and labour. The purpose of the present paper is to use a 'grounded theory' approach to further develop and illustrate that framework, drawing on a recent case study of workplace reform at BHP New Zealand Steel's Glenbrook plant between 1990 and 1994. Case study data on the company's Business Improvement Programme (BIP) shows what 'joint responsibility' actually means in terms of the development of business strategy and work practices built round quality on a day-to-day basis

    Saving the Planet by Cutting Corporate Taxes: A Comparative Case Study Analysis

    Get PDF
    This Article examines corporate tax trends in the context of the press¬ing global issue of climate change. Multinational corporations play a huge role in the global economy. We argue that the role of for-profit corporations should not be limited to making short-term profits for their shareholders. If corporations benefit from corporate tax reduc¬tions, some of that benefit should be shared with society. This Article explores the connection between climate change and corporate activity through a new lens: corporate tax policy. It expands the current inquiry about the impact of taxes on corporations by connecting that discussion to the impact of multinational corporate activity on the global environment. To date, while research has been done on the interaction between corporate tax avoidance and corporate social responsibility, no research has examined the connection between the global trend of corporate tax rate cuts and the increasingly important influence of corporate environmental social responsibility. This Article begins to fill that gap by making a qualitative inquiry into the interac¬tion between effective corporate tax rates, corporate tax cuts, and cor¬porate social responsibility

    Creative industries, new business formation and regional economic growth

    The present study explores the impact exerted by a series of factors and processes including creativity, IPR activities, new business formation and the provision of amenities on economic growth for 103 Italian provinces (NUTS 3) over the period between 2001 and 2006. Provincial growth rates are measured alternatively by value added growth and employment growth. Findings show a positive effect of the increase in the number of firms active in the creative industries, net entry, and a greater provision of leisure amenities on regional economic growth. A large portion of employment in the manufacturing, mining, and energy sector, and a high relative number of university faculties are found to lead to slower economic growth, whereas trademarks, patents, cultural amenities and industrial districts do not affect economic growth. Finally, the share of legal immigrants is found to have a positive impact on employment growth

    Major clinical results of mentoplasty: a systematic review

    Introduction: In the context of oral and maxillofacial surgery, orthognathic surgery (OS) is used to improve the patient's facial appearance and to correct maxillary and mandibular deformities resulting from malocclusions, disease, or trauma. Objective: It was carried out a concise systematic review of the main clinical approaches to genioplasty (genioplasty), as well as the results of more current clinical studies, to show the state of the art of this surgery. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from February 2022 to May 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 108 articles were found. In total, 68 articles were fully evaluated and 23 were included and evaluated in this study. And of the total of 23 articles, only 09 articles were developed as the main clinical results. A total of 16 articles were excluded because they did not meet the GRADE classification, and 45 were excluded because they were at risk of bias. Mentoplasty represents one of the most common auxiliary procedures and may be associated with corrective surgery for dentofacial dysmorphisms. However, care must be taken with mental nerve injuries, asymmetries, and intraoperative bleeding are the main immediate complications of mentoplasty, and to minimize these risks, the ultrasonic piezoelectric osteotomy with the selective cutting of the mineralized structure stands out. Furthermore, one-piece mentoplasty based on a three-dimensional impression model proved to be very successful for the natural modeling of the mandible. Also, it has been shown that the use of piezotomes is advantageous in mentoplasty surgery compared to traditional surgical instruments. In the context of hylotherapy, the results of the study indicate slightly less residual edema at 18°C temperature on the 30th postoperative day. Finally, in orthognathic surgery, a fibrinolytic shutdown is significantly amplified by tranexamic acid
