The noise caused by the movement of users on their chairs in the work environment may indicate structural weaknesses and risk, and still significantly reduce productivity by increasing employees stress level. By understanding the activities to be developed in a work place one may understand what should be necessary to a good development, thereafter a search for improvement of labor activity with the aim of better use of resources in the operation of product use may be done. The analysis of the incremental variation of noise in professional chairs aims to identify its origin and the time the emission of noise starts during the period of use, its development and the major causative agents. Determining the characteristics of the sound of different materials and adjustments mechanisms of the chair can determine how different materials interact with each other. The measurement of these noises in an acoustic isolated room using directional microphones, if recorded and analyzed properly makes it possible to investigate and orientate to suspect elements in order to propose solutions and identify the quality of other similar chairs. Based on the results recommendations can be established for the orientation of users, managers and people responsible for the acquisition of the products, inducing them to review the employment of materials and the choice of the processes of production. These aspects are not covered in the Brazilian ergonomics norms and standards in the use of chairs. 相似文献

The raccoon is often considered a synanthropic species; however, most urban research on this species has been restricted to urban parks or green spaces. Little is known about the persistence of synanthropic characteristics in the raccoon within the urban matrix. We examined density, den selection, home range size, habitat selection, and survival for adult raccoons (Procyon lotor) during summer (June?CAugust) and autumn (September?CNovember) in two residential neighborhoods, Linthicum located inland, and Riviera Beach on a peninsula in the Potomac river, in Southern Maryland. Den site selection varied by gender (P?=?0.0002) and study site (P?=?0.052), and study site interacted with gender (P?=?0.0063), with female raccoons denning preferentially on the ground and male raccoons in human structures in Riviera Beach while in Linthicum females denned preferentially in trees and males avoided human structures. Seasonal home range size was larger for males (P?<?0.0001) than females at both sites. Habitat selection varied at different hierarchical levels, and between gender, season and site. Intersite differences in habitat selection were apparent at the second order and third order scale. Aquatic and urban habitat was ranked high and woodland consistently lowest in second order scale at Riviera Beach while urban habitat was consistently ranked lowest at Linthicum where woodland ranked highest. Between the hierarchal scales (2nd and 3rd order) a difference in habitat selection occurred at Linthicum only where urban habitats ranked lowest at 3rd order. The differences in patterns of habitat selection we observed between two urban sites at different hierarchical scales suggest that resource selection is dependent upon the specific characteristics of the site and that raccoons exhibit variable responses to changes in landscape features. Finally, male survival tended to be lower (P?=?0.079) than female survival in both study sites. Our results reveal that raccoons can continue to exhibit synanthropic characteristics within the urban matrix even in areas with little natural habitat. This ability to adjust to different levels of development allows the raccoon to occur throughout most parts of the urban landscape, which has important management implications for human-raccoon conflicts and disease management. 相似文献

We examine the measurement of individual poverty in an intertemporal context. Our aim is to capture the importance of persistence in a state of poverty and we characterize a corresponding individual intertemporal poverty measure. Our first axiom requires that intertemporal poverty is identical to static poverty in the degenerate single-period case. The remaining two properties express decomposability requirements within poverty spells and across spells in order to reflect the persistence issue. In addition, we axiomatize an aggregation procedure to obtain an intertemporal poverty measure for societies and we illustrate our new index with an application to EU countries. 相似文献

In this article, we attempt to conceptualize the historical development and the governance structure of the transnational organic cotton network from Benin. We aim to discover how the organic cotton production‐consumption network is governed locally and internationally. Existing bodies of literature on international agricultural production networks, in particular the Global Value Chains (GVC) perspective, focus on economic dimensions, but find it difficult to incorporate the sustainability dimension. We favour widening the concept of GVCs beyond economics by acknowledging and including environmental rationalities and the representatives of their interests, not as external elements, but rather as co‐governing or co‐structuring factors (or actors) of sustainable value chains. Our findings reveal that beyond the traditional producer versus buyer dualism, intermediate stakeholders, namely transnational and local environmental NGO networks, are instrumental in the construction, maintenance and transformation of the organic cotton network. It is also apparent that farmers' leaders play an important role in mediating and (re)building trust among organic farmers, though they exert insufficient vertical power in the organic cotton network to control it. 相似文献

Student of Color often reference racial microaggressions when asked to describe their post-secondary experience. The racial battle fatigue framework assists in understanding the cumulative, negative effect of racial microaggressions on psychological, behavioral, and physiological outcomes. This paper assesses the racial battle fatigue framework for African American and Mexican American college students and the impact of coping on racial stress. Results demonstrate that racial microaggressions negatively impact stress responses for African American and Mexican Americans differently, but coping may help alleviate the impact of racial battle fatigue. Universities can address racial microaggressions and negative health outcomes by educating campus constituents about racial microaggressions, addressing Whiteness, and providing education about adaptive coping strategies. 相似文献

Each generation of immigrants has its own challenges; for example, how to maintain already constructed identities among first generation immigrants and how to construct identities of the second generation of immigrants. Numerous literature suggests that the previous studies on these topics have been conducted within larger cities such as London, Glasgow or Edinburgh. This article examines how Muslim immigrants in a small city maintain and modify some aspects of their religious and cultural identities. The data consist of 30 interviews conducted with first and second generation of Muslim immigrants in Scotland, analysis of which suggests the size of the city does not appear to affect daily Muslim practices nor their ability to maintain Muslim identity. Rather, access to shared spaces, such as Inverness Masjid and the local halal meat shop, become critical to how Muslim's maintain and modify their identity in a new place. 相似文献

For some time, it has been argued that stories articulated by leaders are an important vehicle for exercising influence, but stories of leadership might also serve as a means for developing leadership potential. One critical activity involved in leadership is vision formation, which involves constructing and communicating a future state that guides followers in “making sense” of complex organizational events. Like leader visions, analyzing stories also, by nature, evokes sensemaking processes. As a result, analyzing stories of leadership may provide a natural means for practicing the art of sensemaking. In the present investigation, undergraduates were asked to read six short stories about incidents of either pragmatic or charismatic leadership in business settings. After reading each story, questions were asked to encourage sensemaking of story events, causes, and emotions. Participants were subsequently asked to formulate visions for leading a secondary school –– a transfer task. It was found that stronger visions were produced when participants were asked to analyze both story events and the causes of these events. The implications of these findings for the use of leadership stories in leader development initiatives are discussed. 相似文献

We propose that the purposeful sharing of strategic decisions and the process of making and taking those between the dominant coalition of an organization (Strategic Shared Leadership or SSL thereafter), initiated and supported by a focal strategic leader or small team, engenders Organizational Dynamic Capabilities (ODCs) though the transfer of individually-residing DCs within the SSL team, the transformation -co-creation of novel ones and their embeddedness-institutionalization within the organization. It also enhances organizational cognition which mediates the relationship by enriching co-created ODCs and their capacity to deliver reliably change through sensing, seizing and reconfiguring. Accordingly, SSL serves as a co-creator and key predictor of the emergence of ODCs. This helps address the challenges of DCs to marry stability with change, be predictable and to be capable of predicting. 相似文献
