This article describes and highlights the potential contributions that the constructs multifinality, work hope, and possible selves make for designing career counseling interventions and for better understanding possible career‐related factors associated with academic engagement and achievement among urban minority youth. Multifinality may serve as a superordinate orientation because it conceptualizes development as discontinuous and relatively plastic, allowing for youth deemed at risk to follow more hopeful pathways. Work hope and possible selves emphasize the utility of providing urban minority youth with space to answer questions related to what they might achieve and do in the future and who they might become. Together, multifinality, work hope, and possible selves provide a hopeful conceptual framework for career researchers and practitioners. 相似文献

Musicians have long been hampered by the challenge in turning sheet music while their hands are occupied playing an instrument. The sight of a human page turner assisting a pianist during a performance, for instance, is not uncommon. This need for a page turning solution is no less acute during practice sessions, which account for the vast majority of playing time. Despite widespread appreciation of the problem, there have been virtually no robust and affordable products to assist the musician. Recent progress in assistive technology and electronic reading devices offers promising solutions to this long-standing problem. The objective of this paper is to survey the technology landscape and assess the benefits and drawbacks of page turning solutions for musicians. A full range of mechanical and digital page turning products are reviewed. 相似文献

The placement of nasogastric (NG) tubes is known to be prone to error and may lead to serious issues for patient safety and wellbeing. In some instances these have been catastrophic and resulted in the death of the patient. This study sought to explore the potential risks associated with this procedure through the use of systematic prospective risk assessment. The research team used the Prospective Hazard Analysis (PHA) toolkit developed by Ward et al (2010) . The study has shown a wide number of risks that cover equipment design, work organisation, and training issues. The link between equipment design and training provides an important example of the need for a systematic approach to reducing errors and improving resilience in this aspect of healthcare. 相似文献

‘North East India’ composed of different ethnicity is plagued with ethnic assertions and regionalism with that of centuries of alienation. Development is one big issue that need to be address in the region. The North East India after decades of independence is still lagging behind in term of socio, economic, education, political, cultural and social development. A deeper study reveals that movement for separate homeland, regionalism, tribalism, ethnic clash, crime, mass poverty, etc in the region are caused by backwardness of the region. The distinct geo-ethnic and socio-historical characters of North-East India constitute the hotbed of ethnic strife and extreme radicalism. The solution lies partly in resolving the conflict between primordial ethnic loyalties or ‘ethno-nationalism’ and the ‘nationalism of the nation state’, and partly a conscious and voluntary effort to resist corruption and unholy alliance between the militants and the politicians in the region. In any case, ethnic reconciliation would result in the reduction of ethnic violence of all kinds and would eventually restore law and order in the region. When the civil governance in the region will be spared from combating militancy or appeasing the militants, the whole energy of the government would be for strengthening the institutions of local self-government, which act as potential agents of development in the conflict-ridden states of the North-East India. 相似文献

Multiple deployments, a prominent characteristic of operations Enduring Freedom, Iraqi Freedom, and New Dawn, have been linked to increased risk for various mental health conditions. It is also well known that military transitions, such as a change of duty station or discharge, are an inevitable part of military life. While military transitions can be stressful for any service member or veteran, those with mental health conditions face additional challenges. Transition stress can exacerbate a mental health condition that in turn hinders ability to manage the transition, resulting in a cycle of stress. As a result, those receiving mental health care while transitioning often experience difficulty continuing treatment post-transition. This article describes a unique and innovative transition coaching program designed to address this emerging issue. 相似文献

Recent progress in the study of migration history in Japan has cast new light on the influx of Koreans to Japan just after the end of the Second World War in August 1945. Both the Japanese Government and the Supreme Commander for the Allied Powers called this migration illegal entry or smuggling, and tried to suppress it., One important question remains to be solved about this migration; namely; how was it prohibited? Before the Immigration Control Act (1951) was enshrined, and at a time when Koreans in Japan still held Japanese citizenship, how were the authorities able to regard Korean migration to Japan illegal? How did this migration became a political and social problem? Focusing on the legislation process and performance of the law, this article attempts to answer these questions. Politics, legislation, and social interaction all contributed to making the ethnic and legal category of Korean in postwar Japan. 相似文献

ABSTRACTThis paper provides a detailed picture of the sources and types of informal support available to centenarians, depending on their housing and care arrangements. Participants were 112 centenarians and 96 primary contacts of centenarians enrolled in the population-based Second Heidelberg Centenarian Study. Findings indicate that children of centenarians were their primary source of support in daily life. Those without living children had overall less help. Most frequently reported was help with administrative tasks, regardless of centenarians’ residence or living arrangement. All other types of help (e.g., with activities of daily living and housework) were reported by about one-third and were mostly provided by children; centenarians without children were more likely to have friends/neighbors involved in some of these tasks. The one category reported by a third of the centenarians regardless of residence, living arrangements, or presence of a child was help with socializing/companionship. Findings constitute an important step toward identifying and meeting the support needs of centenarians and their families. Policy implications are discussed. 相似文献

In this paper we incorporate a linear demand function to model the price-volume causal relationship into stochastic cost-volume-profit (CVP) analysis. We assume that the objective function is to maximize expected profit; other objective functions are also discussed and compared. A linear stochastic model follows from which probabilistic statements can be easily obtained if the random variables are assumed to be multivariate normal. The basic framework is shown to be a special case of project value maximization where project value is the cash flow of the project discounted for time and risk according to the capital asset pricing model. Moreover, an intertemporal extension that considers inventory is developed. In summary, a new approach to stochastic CVP analysis that incorporates the management decision process in an uncertain environment is developed. 相似文献

Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications
that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD.
This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults
(n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which
persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent
ADHD. 相似文献
