The construction of ergonomic demands: application on artisan fishing using jangada fishing rafts in the beach of Ponta Negra

The present article seeks the process of construction of ergonomics demand referring to the artisan fishing activityfound in Ponta Negra beach located in the city of Natal, Brazil. The instruction/construction of demands correspond to the first stage of Work Ergonomic Analysis and allows the understanding of real issues existent in a work situation, rank them and route the providences. The demand presented on this study, features itself as a induced demand, process which some potential demands or hypothetical demands are taken to an organization, after a preview analysis of the work aimed by the study, resulting from a theoretical research (state of the art) and/or from analysis of a reference situation (state of practice), where demands hypothesis are taken in consideration about the pretended work. The demands construction process using interactional methods and techniques, observation methods and techniques and bibliographic research, researches in state of reference or document. This article demonstrates the efficiency of the methodological choice to construct real ergonomic demands and highlights the importance of social construction on that process, which main goal is to refer the ergonomic actions that allow the improvement of work and life conditions for the fishers and sustainability to Jangadeira activity.     

Universal design and accessibility: an approach of the influence of muscle strength loss in the risk of falls in the elderly

This study was conducted with older adults living in a long-stay institution in the city of Foz do Iguacu, Parana, Brazil with the objective of assessing the influence of muscle strength loss in the risk of falls. The sample consisted of 65 elderly who walk without the aid of support for locomotion, 37 women and 28 men, aged between 67 and 80 years. The risk of falls was assessed through the TUG test. To determine the handgrip strength, a hand dynamometer model Jamar ( was used, which provides the result in kg / force (kgf), being held only with the dominant hand. The results showed that in the last 12 months, only 32% of the elderly surveyed had no fall and the average handgrip strength was 24.32 ( 11.22 kgf; 40% had one fall and the average handgrip strength was 23.82 ( 10.18 kgf; 8% had two falls and the average handgrip strength was 19.48 ( 8.21 kgf and 20% had more than one fall and the average handgrip strength of 18.13 ( 7.33 Kgf., indicating that the force levels are statistically lower among elderly at high risk of falls (p> 0.05). It was concluded that the lower the force level, the greater the likelihood of falls. Thus, it is important to stress that due to the loss of muscle strength, all ergonomic hazards and architectural barriers must be removed so that older adults can perform their tasks more easily, with comfort and safety.     

Measuring educational inequalities: a method and an application to Albania

In this paper, we investigate whether educational inequalities stem from differences between families or within families. In a poor economy, schooling is costly for parents, and education is likely to be unequally distributed among siblings. Drawing on discrete ordered choice models, we present a simple method to estimate the between and within components of both the explained and unexplained variance in education. For our empirical analysis, we use the Living Standard Measurement Study survey conducted in 2002 in Albania. We explain about 40% of the total variance and find that inequalities in education are mainly due to differences between families. Differences within families are smaller and are far less easily explained.     

Remittances,Business Cycles and Poverty: The Recent Turkish Experience

We investigate whether remittances sent to Turkey by Turkish workers living in Germany are countercyclical or procyclical with Turkish and German national outputs and discuss possible reasons underlying the resulting patterns and their implications. We also take up a previously unexplored issue and discuss poverty alleviation potential of remittances at a macroeconomic level by examining the statistical properties of any co‐movements between remittances cycles and cycles in consumption spending on food and durable goods in Turkey. Our results reveal that real remittance flows from Germany to Turkey move procyclically with the real output in Turkey, and are primarily driven by (largely independent of) the developments in the Turkish economy (German economy). We also find that remittances cycles remain procyclical to the consumption cycles throughout our sample period. This direct co‐movement between the two cycles becomes synchronous, however, only after a phase shift occurring around 1992, pointing to the increasing role of the level of economic activity in Turkey as the leading determinant of remittance receipts from Germany and the declining strength of consumption smoothing motive over time. Our results all together point out a low potential for remittances sent from Germany to reduce poverty in Turkey, at least as far as the past fifteen years are concerned.     

Who uses tips as a reward for service and when? An examination of potential moderators of the service-tipping relationship

Consumers in many countries often give voluntary payments of money (tips) to the workers who have served them. These tips are supposed to be a reward for service and research indicates that they do increase with customers’ perceptions of service quality. This paper contributes to the service-tipping literature by examining numerous potential moderators of this relationship in two studies. Results indicate that the service-tipping relationship is robust across meal type, day of week, sex and race of server as well as customers’ alcohol consumption, education, income, race, worship frequency, and hospitality work experience, but that it is stronger for older consumers than for younger ones and for parties with large bills than for parties with smaller bills. The practical and theoretical implications of these and other findings are discussed.     

Email subject lines and response rates to invitations to participate in a web survey and a face-to-face interview: the sound of silence

This paper investigates the relationship between blank and non-blank email subject lines on levels of response to a solicitation to participate in an interview, and on participation in a web survey. Email use has grown substantially in recent years, presenting significant opportunity to the empiricist seeking research respondents. However, response to emails may be low because growth in the sheer volume of messages that individuals receive per day has led to a sense of ‘email overload’, and faced with the challenge of personal email management, many recipients choose to ignore some messages, or do not read them all fully. Drawing on information gap theory, we expected that sending an invitation with a blank subject line would induce a sense of curiosity in recipients that would improve email response and willingness to participate in research studies. However, findings from research with two samples with different propensities to participate in research (academics and business owners) revealed that an email invitation with a blank subject line does not increase overall response rates to a web survey and a face-to-face interview over either an informative subject line or a provocative subject line, but that it does prompt a greater number of active refusals. Based on this finding, recommendations for researchers are outlined.     

Rehabilitation programs for elderly women inpatients with schizophrenia

This study aims to describe rehabilitation and resocialization methods we believe to be appropriate for application to female patients with schizophrenia, in a psychiatric unit with a predominantly older population. We briefly describe the unit and the interventions used as an example of the proposed rehabilitation and resocialization methods applied. The article provides an overview to guide accurate intervention, particularly in inpatient women, in different types of cognitive impairment under the broad category of schizophrenia. Our clinical approach includes a token economy approach, cognitive remediation therapy, and social skills training. The token economy intervention is particularly directed to patients that present with a high mental deterioration and/or debility. Cognitive remediation training is applicable to subjects with both cognitive and social dysfunction, but that do not possess signs of an organic cerebral illness or of substance abuse. Social skills training can be the third step to resocialization, training verbal and nonverbal communication competencies.     

Modeling stock markets’ volatility using GARCH models with Normal,Student’s <Emphasis Type=Italic>t</Emphasis> and stable Paretian distributions

As GARCH models and stable Paretian distributions have been revisited in the recent past with the papers of Hansen and Lunde (J Appl Econom 20: 873–889, 2005) and Bidarkota and McCulloch (Quant Finance 4: 256–265, 2004), respectively, in this paper we discuss alternative conditional distributional models for the daily returns of the US, German and Portuguese main stock market indexes, considering ARMA-GARCH models driven by Normal, Student’s t and stable Paretian distributed innovations. We find that a GARCH model with stable Paretian innovations fits returns clearly better than the more popular Normal distribution and slightly better than the Student’s t distribution. However, the Student’s t outperforms the Normal and stable Paretian distributions when the out-of-sample density forecasts are considered.     

The Access/Impact Problem and the Green and Gold Roads to Open Access: An Update

The research access/impact problem arises because journal articles are not accessible to all of their would-be users; hence, they are losing potential research impact. The solution is to make all articles open access (OA, i.e., accessible online, free for all). OA articles have significantly higher citation impact than non-OA articles. There are two roads to OA: the “golden” road (publish your article in an OA journal) and the “green” road (publish your article in a non-OA journal but also self-archive it in an OA archive). About 10% of journals are gold, but over 90% are already green (i.e., they have given their authors the green light to self-archive); yet only about 10–20% of articles have been self-archived. To reach 100% OA, self-archiving needs to be mandated by researchers’ employers and funders, as they are now increasingly beginning to do.
