In the current study, we used a qualitative approach to investigate relevant beliefs and norms associated with codeine and promethazine hydrochloride cough syrup (CPHCS) consumption, initiation, and perceived addiction among 48 alternative school students who identified themselves as current CPHCS users. In general, both boys and girls believed that CPHCS addiction started during an individual's initial consumption. A majority of both groups reported that their second CPHCS event was initiated during the same or next day after their first event. Our findings suggest that friends and an innovative form of hip-hop music called "screw" are strong reinforcers of CPHCS use. 相似文献

A population of 72 bifocal wearers was studied to determine the relationship between VDT (video display terminal) placement for those who reported musculoskeletal pain and those who did not. The mean hours worked was 50.4 minutes (p=0.003) greater for those who reported head/neck pain versus those who did not and 48.6 minutes (p=0.004) greater for those who reported shoulder/arm pain that those who did not. There was no statistically significant difference between the means of monitor height, distance, or angle for those who reported pain symptoms versus those who did not. This study indicates that, self reported pain symptoms are correlated with hours of VDT work and that there appears to be a threshold at approximately five hours for pain symptoms among bifocal wearers. No such correlation can be made for monitor placement 相似文献

This study explores how online publics are engaging with organizations by creating and sharing brand-related content online, outside corporate-controlled communication environments. This research employs a quantitative content analysis of memes shared on the social networking site Imgur to reveal how user-generated content conveys meaning about organizations. The analysis reveals brand-centric memes are generally classified as orphan memes, or memes that have distinct textual and visual characteristics separating them from established or emerging meme families. Memes about organizations are neither an overwhelming reflection of biting criticism or support, but rather a reflection of online public engagement with organizations that primarily use humor and textual brand features (or quiddities) to convey their commitment and satisfaction with the organization and unite meme families. 相似文献

ABSTRACT This study explored and conceptualised service users’ experiences in online outreach projects supported by the Hong Kong SAR government. Fifteen active users were interviewed. The study used thematic analysis to explore service users’ experiences that might not have been possible without technology. Participant utterances were non-mutually-exclusively tagged with a specific theme. Each utterance reflected an aspect of user experience which combined a technical component with a service-need component. Six themes were identified, including: (i) Personalised newsfeeds help identify service information and news, (ii) Online status indicators improve service accessibility, (iii) Online communications enable a disinhibition effect, (iv) Asynchronous communications facilitate continual feedback loops, (v) Incomplete communicative modalities may cause misunderstanding and (vi) Asynchronous communication may disrupt conversations. The findings reveal that there are middle-level concepts between broad social work concepts and ever-changing technology. Implications for research and practice are discussed. 相似文献

We consider the invertibility (injectivity) of a nonparametric nonseparable demand system. Invertibility of demand is important in several contexts, including identification of demand, estimation of demand, testing of revealed preference, and economic theory exploiting existence of an inverse demand function or (in an exchange economy) uniqueness of Walrasian equilibrium prices. We introduce the notion of “connected substitutes” and show that this structure is sufficient for invertibility. The connected substitutes conditions require weak substitution between all goods and sufficient strict substitution to necessitate treating them in a single demand system. The connected substitutes conditions have transparent economic interpretation, are easily checked, and are satisfied in many standard models. They need only hold under some transformation of demand and can accommodate many models in which goods are complements. They allow one to show invertibility without strict gross substitutes, functional form restrictions, smoothness assumptions, or strong domain restrictions. When the restriction to weak substitutes is maintained, our sufficient conditions are also “nearly necessary” for even local invertibility. 相似文献

Abstract This study reports on the short-term effects of an educational programme for immediate supervisors on employees' back pain problems. The course was designed to help supervisors more efficiently deal with employees returning to work after being treated for back pain. Forty-seven supervisors who had personnel either undergoing treatment for back pain problems or were candidates for this treatment were invited to attend a one-day course. This educational package consisted of information about back pain and stressed specific behaviours which supervisors could use to help their employees successfully return to work. The results showed that 78% of the supervisors found the course to be satisfactory enough to recommend it to a colleague without hesitation. Furthermore, independent ratings made by the supervisors and their employees suggested that supervisors complied with the recommended programme. Returning employees, moreover, gave their supervisors significantly higher ratings of support than a control group whose supervisors had not attended the educational programme. It was concluded that an educational programme which alters specific supervisory behaviours may be an effective method of assisting employee return to work after treatment for back pain. Further research is needed to determine the long-term effects of such a programme on absenteeism due to illness. 相似文献

This paper discusses an example of community action mounted in a rural region of New South Wales, Australia, in response to proposals by the State Government to rationalise agricultural research stations operated by the Department of Primary Industries. Informed by a Foucaultian understanding of power and the concept of governmentality, neoliberalism is theorised as being the broad governmental context in which rationalisation proposals were put forward. Recent literature drawing on this theoretical perspective has emphasised that neoliberalism is enacted through a relationship of power, and is not monolithic or inevitable. Neoliberalism is always negotiated by those seeking to govern and those who are the object of such governmental actions. This paper analyses how plans to rationalise publicly funded agricultural research stations were opposed by those seeking to keep research facilities open in the case study area. The paper discusses the methods and scope of community action and, drawing on interviews, identifies a series of discourses articulated by campaigners. Non-local actors were depicted as uncaring and insensitive. In contrast, campaigners discussed the emergence of a ‘city-country divide’ in domestic politics; the need for specialist agricultural knowledge given the region's unique geographical location; and local impacts of an economic, social and emotional nature. Central were discourses of maintaining community, tradition, and continuity in unique local places defined by their climate, biophysical environment and economy. These were ‘counter-geographies’ that sought (successfully, it would transpire) to disrupt the state's imagined geography of a homogenous and flexible administrative space in which research services could be relocated wherever most efficient. Important too were embodied resistances to the way rural industries and people were subjected. Campaigners refused to accept preferred codes of neoliberal behaviour (particularly mobility and rationality) and instead demanded respect for their careers, families and communities. Important considerations are suggested for further research on impacts and negotiations of neoliberalism. This study particularly highlights the successes—as well as contradictions and limitations—of arguments that construct rural places as socialised, unique and unfairly treated (by governments), in opposition to metropolitan dominance and ‘placeless’ neoliberalism. 相似文献

The cognitive and behavioral status at age six years of 185 children of adolescent mothers (60.5% boys) were assessed using the mother (CBCL) and teacher (TRF) report forms of the Child Behavior Checklist and the Bracken Basic Concepts Scale. There was evidence for impairment in all areas of functioning. More than half of the sample exceeded the borderline clinical cutoff (T = 60) on either the CBCL or TRF Total Problem score, and nearly half the sample had Bracken scores that were more than 1 SD below the normative mean. Only 26.9% of the children were in the normal range on all three measures. These results are discussed in terms of implications for social work practice with children and adolescent mother families. 相似文献
