Physical workload during firefighting in Chilean volunteers

The study was performed in a sample of 39 firemen. The state of health for each fire fighter was evaluated by means of a clinical examination and also through some specific exams. Aerobic capacity was estimated as an indicator of physical fitness. In each load, cardiac frequency and oxygen consumption were measured under a steady state condition. Additionally, body composition was calculated using a Tanita professional scale. Physical effort at work was determined by measuring cardiac frequency using a telemetric unit. Evaluations were carried out during night shifts, registering information under the following conditions: night shifts without emergency, fire simulation, training exercises and real fire fighting. In general terms, it is possible to state that fire fighters are healthy according to the result of the clinical examination. However, it is very important to highlight that 70% of the firemen consume alcohol and 80% were smokers. The average aerobic capacity of the sample was 2.6 l/min or 34.5 ml/kg/min. In terms of overweight and obesity, the body mass index was 25.7, whereas the percentage fat mass reached an average of 22.9 %. The cardiovascular load in the night shifts without emergencies did not surpass 40%, which in Chile is considered the highest limit for sustained work. However, during training, simulations and real fires, the firemen had higher cardiac frequencies, reaching peak levels close to 100% cardiovascular load.     

Nomadictates: Staging Roots and Routes in The Essaouira Gnawa Festival

The aim of this paper is to study Moroccan music festivals, especially the Essaouira Gnawa festival, against the existing theories on globalization, while contributing new concepts (nomadictates, recurrents and exclusives, wes-turn/eas-turn modernity) aimed at overcoming the reductionism and totalitarianism of the cultural imperialism thesis with regard to artefacts and cultural texts. The grotesque circulation of western cultural artefacts is justifiably judged to be agonizing for cultural theorists who want to be sure that the unequal transmissions of products across the world will not harm the local cultural, linguistic, and economic capital of the less dominant other (Hall, 1992 Hall, S. (ed.) (1992). Encoding/decoding, Culture, media, language: Working papers in cultural studies, 1972–79 (London: Routledge). [Google Scholar]). We will examine music and festivity in relation to world flows, while holding the argument that the appropriation of western artefacts locally has always been part of a not-so-novel process of mobility of what we call world cultural nomadictates (nomadic dictates). To drive this idea home, we will open the discussion at hand on to existing controversies around notions of place, authenticity, and circulation. The Essaouira festival of Gnawa music and the cosmopolitan Gnawa artist Hakmoun are employed as examples to cover the translocal dynamics of cultural nomadism, whereby humans and objects vacillate constantly between roots and routes.     

Residual Responses to Change Patterns of Autocorrelated Processes

This article studies the residual behaviour of various stationary processes in the presence of change patterns. Three types of change patterns are considered, Additive Outliers, Innovative Outliers and Level Shift. The knowledge of the residual behaviour is important for monitoring production processes. A new method of residual process control is proposed, the patterns chart. In addition to the advantage of detecting change patterns, it distinguishes their nature. The patterns chart's performance is compared to the performance of the special causes control (SCC) chart based on average run length. The results show that the proposed method performs better than a SCC chart. A real case study illustrates that the patterns chart has all the desirable properties of a SCC chart and it overcomes the negative ones.     

On a theorem of graybill

Graybill (1976) gives a theorem for testing variance components in balanced random models. Unfortunately, the theorem does not hold true. We pin down the reason that causes the theorem to fail and give a correct version of it.     

House Demolition and Mental Health: Victims and Witnesses

This research examines the immediate effects of losing one's home and witnessing the demolition of others' houses on the mental health of Palestinian adults and children. The loss group consisted of 47 adults whose homes were demolished, the witness group of 24 adults who witnessed the house demolition, and the control group of 33 adults. The groups were compared for their anxiety, depression, and paranoiac symptoms. In addition, 38 children in the loss group, 36 children in the witness group, and 50 children in the control group were compared for their psychological symptoms. The results showed that adults who were exposed to house demolition showed a higher level of anxiety, depression, and paranoiac symptoms than the witness and control groups. The children in the loss group showed a higher level of psychological symptoms than the children in the witness and control groups. The witness group differed from the control group in having more depression among women and more psychological symptoms among children. Women suffered more from anxiety, depression, and paranoiac symptoms than men in the loss and witness groups but not in the control group.     

Metaphors we discriminate by: Naturalized themes in Austrian newspaper articles about asylum seekers

With specific reference to the use of metaphor in Austrian newspaper reports on the arrival of Kurdish asylum seekers in Italy in January 1998, this study suggests ways in which cognitive metaphor theory can be given a stronger socio-political dimension. The dominant metaphors portray the asylum seekers as water, as criminals, or as an invading army. The repeated use of these themes in relatively fixed lexical and syntactic forms and across all the newspapers seems to indicate that they have become accepted as the 'natural' way of describing the situation. It will be argued that the 'naturalization' of particular metaphors can contribute to a blurring of the boundaries between the literal and the non-literal.     

Understanding the Elusive Black Box of Dynamic Capabilities

A major challenge for managers in turbulent environments is to make sound decisions quickly. Dynamic capabilities have been proposed as a means for addressing turbulent environments by helping managers extend, modify, and reconfigure existing operational capabilities into new ones that better match the environment. However, because dynamic capabilities have been viewed as an elusive black box, it is difficult for managers to make sound decisions in turbulent environments if they cannot effectively measure dynamic capabilities. Therefore, we first seek to propose a measurable model of dynamic capabilities by conceptualizing, operationalizing, and measuring dynamic capabilities. Specifically, drawing upon the dynamic capabilities literature, we identify a set of capabilities—sensing the environment, learning, coordinating, and integrating—that help reconfigure existing operational capabilities into new ones that better match the environment. Second, we propose a structural model where dynamic capabilities influence performance by reconfiguring existing operational capabilities in the context of new product development (NPD). Data from 180 NPD units support both the measurable model of dynamic capabilities and also the structural model by which dynamic capabilities influence performance in NPD by reconfiguring operational capabilities, particularly in higher levels of environmental turbulence. The study's implications for managerial decision making in turbulent environments by capturing the elusive black box of dynamic capabilities are discussed.     

The willingness to emigrate in six MENA countries: The role of post-revolutionary stress

This paper studies the determinants of emigration from six Middle East and North Africa (MENA) countries in light of the Arab Spring of 2011. The aim is to determine if the economically unfortunate events which occurred as a result of the Arab Spring, resulted in a brain drain for many countries. The paper's analysis is conducted using the Arab Transformation Project dataset of the year 2014 by employing an ordered probit model. The paper's main conclusion is that sentiments of unhappiness appear to be the primary determinant of the willingness to emigrate. Other post-revolutionary feelings include lack of trust and political and democratic discontent, which highly encourage the willingness to emigrate. In addition, socio-economic factors, such as being young, male, and highly educated, contribute to the willingness to emigrate. However, married individuals are less likely to consider emigration.
