Item validity of the physical demands from the Dictionary of Occupational Titles for the functional capacity evaluation of clients with chronic back pain

This study assessed the item validity of 15 of the physical demands from the Dictionary of Occupational Titles (DOT), as evaluated in a new approach to functional capacity evaluation (FCE) for clients with chronic back pain, the Gibson Approach to FCE (GAPP FCE). Fifty-two occupational therapists were sent the specifications of the items in the GAPP FCE procedures and were asked to rate the items in terms of item-objective congruence, relevance and difficulty. A response rate of 59.2% was obtained. The majority of the therapists agreed that most of the items were congruent with the objectives based on the definition of the physical demands from the DOT. The items evaluating Balancing and Pushing and Pulling had the lowest item-objective congruence. The evaluation of Balancing and the Lifting, Carrying and Pushing and Pulling of loads greater than light-medium weight (10–16 kg) were not considered significantly relevant. Concerns were raised about the difficulty and safety of the evaluation of Lifting, Carrying and Pushing and Pulling with clients with chronic back pain, particularly if the therapist evaluates the manual handling of medium to heavy loads. These results may have implications for other FCEs, particularly those which are based on the DOT, or when assessing clients with chronic back pain.

The role of audiometry in the prevention of occupational deafness

The research set out to test three main hypotheses derived from a summary of literature relevant to the use of audiometry in industry. These hypotheses were: (1) performing audiometry increases the probability that hearing protectors, once issued, will be worn; (2) audiometry is considered by workers to be evidence of their employer's concern for their welfare; (3) audiometry is associated with common law claims by workers against employers for alleged occupational deafness. Six subsidiary hypotheses were also developed. Four methods of data collection were used: (1) attitude questionnaires were administered to samples of workers drawn from an industrial company performing audiometry and two industrial companies not performing audiometry; (2) a postal questionnaire was sent out to industrial medical officers; (3) surveys were undertaken to assess the proportion of the workforce in each of eight industrial companies that was wearing personal hearing protectors that had been provided; (4) structured interviews were carried out with relevant management level personnel in each of five industrial companies. Factor analysis was the main statistical analytic technique used. The data supported all three main hypotheses. Audiometry was also examined as an example of medical screening procedure. It was argued that the validation of medical screening procedures requires the satisfaction of attitudinal or motivational validation criteria in addition to the biological and economic criteria currently used. It was concluded that industrial audiometry failed to satisfy such attitudinal or motivational criteria and so should not be part of a programme of screening for occupational deafness. It was also concluded that industrial audiometry may be useful in creating awareness, amongst workers, of occupational deafness. It was argued that the only profitable approach to investigating the role of audiometry in preventing occupational deafness is to study the attitudes and perceptions of everyone involved.

Entrepreneurship in the neighborhood:shifting patterns of economic activities in residential neighborhoods in five dutch cities

Cities are oftentimes seen as undergoing a process of "emergence" in the "new economy." However, this process has largely remained empirically underdetermined. This article examines the intra-city geography of emerging businesses in newly dominant sectors of the urban economy. The change in dominant sectors coincides with a shift towards small- and medium-sized businesses, creating new economic opportunities for urban residential areas. The residential neighborhood is introduced as a place where supply and demand side drivers operate to attract or limit such new economic activity. Allen Scott's perspective of the cognitive-cultural economy is used to analyze which neighborhoods are flourishing sites of the cognitive-cultural sectors. His perspective on industries that are on the rise in urban environments and their growth potential proves very valuable. Social demographic characteristics on the level of the neighborhood are used as predictors of the composition of the local economy. The analyses show that in particular wealthy, gentrified neighborhoods are more prone than others to becoming "hubs" of the cognitive-cultural economy. However, disadvantaged neighborhoods may under certain conditions serve as incubators for business start-ups as they offer low-rent office spaces. This has important consequences for their future economic growth potential as well as the distribution of successful businesses in the city. © 2013 Urban Affairs Association.

Az innováció hatása a vállalati teljesítményre és versenyképességre (The impact of innovation activities on firm's performance and competitiveness)

A tanulmány az innovációnak a vállalati teljesítményre és a versenyképességre gyakorolt hatását vizsgálja, valamint a magyarországi innováció gazdasági környezetének néhány elemét próbálja feltérképezni a Budapesti Corvinus Egyetem Versenyképesség Kutató Központjának 2009-es felmérése alapján. A termékinnováció fontos szerepet játszik a versenyképes vállalatok sikerében, azonban - elsősorban adatbázisunk keresztmetszeti jellege miatt - az eljárásinnovációról ezt nem tudjuk megállapítani. Ugyancsak nem találtunk szignifikáns kapcsolatot az innováció és a termelékenység között. Az innovatív vállalatok nagyobb valószínűséggel vesznek részt a külkereskedelemben, nagyobb arányban vannak külföldi tulajdonban, s az innovációs folyamat során leginkább saját tudásbázisukra támaszkodnak. Az innováció egyik fő hátráltató tényezőjének tartják az állam szerepét, gyakran néznek szembe finanszírozási problémákkal és a piaci szereplők új termékek iránti igénytelenségével. _____ The paper deals with the impact of innovation on performance and competitiveness based on firm-level data. The research is based on a survey conducted by the Competitiveness Research Centre at Budapest Corvinus University. According to the econometric analysis, the firms that are more innovative are export oriented and foreign owned. Product innovation has an eminent role in competitiveness, but no significant relationship was found between innovation and productivity. As for sources of innovation, internal ones are more important than universities, customers or open sources. Firms themselves perceive legislation and taxation as highly important factors that hamper their innovation activity.

The conflict resolution behaviors of occupational therapy students as a function of the personality types, demographic characteristics and contextual factors

Interpersonal conflicts have the potential for detrimental consequences if not managed successfully. Understanding the factors that contribute to conflict resolution has implications for interpersonal relationships and the workplace. Researchers have suggested that personality plays an important and predictable role in conflict resolution behaviors (Chanin & Schneer, 1984; Kilmann & Thomas, 1975; Mills, Robey & Smith, 1985). However, other investigators have contended that contextual factors are important contributors in triggering the behavioral responses (Shoda & Mischel, 2000; Mischel & Shoda, 1995). The purpose of this study was to investigate the relationships among personality types, demographic characteristics and contextual factors on the conflict resolution behaviors reported by graduate occupational therapy students (n = 125). ^ The study design was correlational. The Myers Briggs Type Indicator (MBTI) and the Thomas-Kilmann (MODE) Instrument were used to establish the personality types and the context independent conflict resolution behaviors respectively. The effects of contextual factors of task vs. relationship and power were measured with the Conflict Case Scenarios Questionnaire (CCSQ). One-way ANOVA and linear regression procedures were used to test the relationships between personality types and demographic characteristics with the context independent conflict behaviors. Chi-Square procedures of the personality types by contextual conditions ascertained the effects of contexts in modifying the resolution modes. Descriptive statistics established a profile of the sample. ^ The results of the hypotheses tests revealed significant relationships between the personality types of feeling-thinking and sensing-intuition with the conflict resolution behaviors. The contextual attributes of task vs. relationship orientation and of peer vs. supervisor relationships were shown to modify the conflict behaviors. Furthermore, demographic characteristics of age, gender, GPA and educational background were shown to have an effect on the conflict resolution behaviors. The knowledge gained has implications for students' training, specifically understanding their styles and use of effective conflict resolution strategies. It also contributes to the knowledge on management approaches and interpersonal competencies and how this might facilitate the students' transition to the clinical role. ^

Campus Design: Locating a new center of international studies

FIU's campus master plan should portray an overall concept of the University's vision. Its design should represent a distinctive sense of institutional purpose. Its architecture should support the campus design in the realization of an ideal academic environment. The present master plan of Florida International University (FIU) offers neither a clear typology of architectural elements nor adequate relationships and connections between buildings. FIU needs to enhance its master plan with an architectural and urban vocabulary that creates a better environment. This thesis will examine FIU's present master plan, explaining the history of its development. Further, it will critically examine the quality of the campus, highlighting the success and failure of its various parts. The unrealized potential of the campus' original vision will be juxtaposed to the built reality. In addition, FlU's planning strategies will be parallel with the planning of several master plans of American universities. Finally, this thesis will propose a set of criteria for the inclusion of a new building in the campus master plan. The Center of International Study will be the catalyst that would bring into focus the university's vision. As a means to prove the validity of these criteria, a new location for the center of international studies will be selected, and a schematic architectural proposal will be made.

The sexual division of labor : the impact of organizational change upon group cohesion and the creation of occupational identity

The purpose of this research is to identify the impact of recent organizational change upon the culture of firefighting. The experiences of female firefighters were utilized as a measure of cultural change. A purposive sample of twenty-seven male and female firefighters were interviewed in a semi-structured format about their experiences in the fire service. This research found that the culture of firefighting has adjusted to the presence of previously excluded groups by forging a division among the identities and roles of male and female firefighters. The white, male firefighters, who have traditionally constituted a majority of the workforce, have continued to identify with traditional firefighter roles and reported high levels of cohesion. In contrast, the female firefighters showed a greater variance in their identification with traditional roles and decreased levels of cohesion with the main body of the group.

Detecting stealthy attacks: Efficient monitoring of suspicious activities on computer networks

Stealthy attackers move patiently through computer networks - taking days, weeks or months to accomplish their objectives in order to avoid detection. As networks scale up in size and speed, monitoring for such attack attempts is increasingly a challenge. This paper presents an efficient monitoring technique for stealthy attacks. It investigates the feasibility of proposed method under number of different test cases and examines how design of the network affects the detection. A methodological way for tracing anonymous stealthy activities to their approximate sources is also presented. The Bayesian fusion along with traffic sampling is employed as a data reduction method. The proposed method has the ability to monitor stealthy activities using 10-20% size sampling rates without degrading the quality of detection.
